This study aimed to collect and document the ethnopharmacological data on herbal remedies, which traditionally used by Palestinian healers in the rural areas of the West Bank area for the treatment of infertility in males and females. METHODS: Using a semi-structured questionnaire, an ethnopharmacological survey of medicinal plants used for the treatment of infertility in the West Bank area of Palestine was investigated. This survey involved 51 traditional healers which were interviewed in rural areas from 9 Palestinian regions. RESULTS: Information about 31 plants used in the treatment of infertility in females and 24 plants used in the treatment of infertility in males were collected. This information including names of plants, parts used, mode and methods of preparation which were obtained from 51 traditional healers interviewed in rural areas of 9 regions of the West Bank/Palestine. This investigation is the first scientific work in the Middle East area which collected information about herbal remedies used by local Palestinian traditional healers for the treatments of infertility in males and females. The highest Frequency of Citation (FC) of herbal remedies used in case of infertility in females, were 98.04% for pollen grains from Ceratonia siliqua, 88.24% for Anastatica hierochuntica fruits and 84.31% for Parietaria judaica leaves, while the highest Frequency of Citation (FC) of herbal remedies used in case of infertility in males were 96.08% for Ferula hermonis roots, 88.24% for Phlomis brachyodon leaves and 86.27% for Phoenix dactylifera pollen grains. CONCLUSION: Herbal healers in the West Bank area of Palestine have a wide range of herbal remedies used in case of infertility in males and in females. Unfortunately, most of them lack scientific evidence of pharmacological or toxicological nature. Therefore, the information obtained in this study can serve as a scientific base for further investigations to determine their efficacy and safety which might contribute to better integration of Palestinian traditional medicine into the global health system in the future.

This present study was designed to elucidate this protective activity in a rat model with streptozotocin (STZ)-induced DN and to explore the possible underlying mechanism. METHODS: Adult Sprague Dawley (SD) rats were induced to develop DN through intraperitoneal injection of STZ (60 mg/kg). Animals were orally administered saline, WSJPR at 7.5, 15, 30 g/kg, and valsartan (25 mg/kg) daily for 8 weeks. Blood and 24-h urine samples of each rat were collected for biochemical examination at 2-week intervals. Microcirculatory blood flow in the renal cortex and hemorheology index were also measured. At the end of 8 weeks, all rats were sacrificed to obtain the kidney tissues for histological examination and reverse transcription polymerase chain reaction (RT-PCR) was used to analyze the transcriptional levels of nephrin and podocin genes. RESULTS: WSJPR could improve serum total protein (TP) and albumin (ALB), reduce the excretion rates of urine-TP (U-TP), urine-ALB (U-ALB) and urine urea nitrogen (UUN) (P < 0.05), although it did not significantly alter the hyperglycemia. In addition, treatment with WSJPR could strongly reduce blood flow, erythrocyte aggregation index, and ameliorate microcirculation. In histological measurement, WSJPR-treated rats showed a significant amelioration in glomerular hypertrophy and mesangial expansion. By RT-PCR, we found WSJPR up-regulated the nephrin and podocin expression at mRNA levels. CONCLUSION: This study suggested that WSJPR could effectively relieve renal damage and improve renal function of DN rats by ameliorating metabolism disorder and increasing the gene expression of nephrin and podocin, which might be a useful approach for the treatment of DN.

Distal acupoint and peri-incisional stimulation are both used for relieving acute postoperative pain in hospital. Our objective was to assess and compare the effects of distal and peri-incisional stimulation on postoperative pain in open abdominal surgery. METHODS: MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials and Chinese databases CNKI and Wanfangdata were searched to identify eligible randomized controlled trials. Intensity of postoperative pain, opioid consumption and related data were extracted and analyzed using a random effects model. Risk of bias was assessed. Subgroup analyses were conducted when data were enough. RESULTS: Thirty-five trials were included, in which 17 trials studied distal stimulation, another 17 trials studied peri-incisional stimulation and one studied the combination of the two approaches. No studies that directly compared the two approaches were identified. Subgroup analysis showed that both distal and peri-incisional stimulation significantly alleviated postoperative resting and movement pain from 4 h to 48 h after surgery by 6 to 25 mm on a 100 mm visual analogue scale. Peri-incisional stimulation showed a better reduction in postoperative opioid consumption. No studies compared the effects of the combined peri-incisional and distal stimulation with either mode alone. Overall the quality of evidence was moderate due to a lack of blinding in some studies, and unclear risk of allocation concealment. CONCLUSION: Both distal and peri-incisional modes of stimulation were effective in reducing postoperative pain. Whether a combined peri-incisional stimulation and distal acupuncture has superior results requires further studies.

In our preliminary study, β-catenin conditional activation (cAct) mice that specifically over-express β-catenin gene in cartilage chondrocyte exhibits osteoarthritis-like phenotype in the lumbar disc and knee joint. Therefore, we used the mice to model FJ-OA and test the potential curative effect of Velvet Antler Polypeptide (VAP) on this mice model. METHODS: We tested the effect of VAP on β-catenin conditional activation mice, and used Cre negative littermates as controls. Micro-CT, histology and histomorphometry analysis were performed to evaluate the curative effect of VAP on mice facet joint-like phenotype. Expression of β-catenin and collagen II was detected by immunohistochemistry (IHC) and western-blot., MMP13, ADAMTS4 and ADAMTS5 was detected by immunofluorescence (IF). RT-PCR analysis was preformed to detect mRNA expression of cartilage degrading enzymes, such as MMP13, ADAMTS4 and ADAMTS5. RESULTS: Results of micro-CT (μCT) analysis showed that VAP could partially reverse lumbar disc osteophyte formation observed in β-catenin(ex3) mice. Histology data revealed VAP partially improved facet joint cartilage tissue invades. Histomorphometry analysis showed an increase in total cartilage area after VAP treatment. IHC show that VAP reduced β-catenin protein levels and moderately up-regulated collagen II protein levels. RT-PCR and IF data showed that VAP down-regulated the expression of extracellular matrix synthesis (ECM) degradation enzymes MMP13, ADAMTS4 and ADAMTS5. CONCLUSION: Taken together, VAP may modulate ECM by inhibits MMP13, ADAMTS4 and ADAMTS5 via Wnt /β-catenin signaling pathway. Velvet Antler Polypeptide may be a potential medicine for FJ-OA.

The aim of this cross-sectional survey was to analyze yoga-associated adverse effects and their correlates. METHODS: A cross-sectional anonymous national online survey among German yoga practitioners (n = 1702; 88.9% female; 47.2 ± 10.8 years) was conducted from January to June 2016. Participants were queried regarding their yoga practice, i.e. yoga styles used, length and intensity of yoga practice, practice patterns, and whether they had experienced acute or chronic adverse effects of their yoga practice. Independent predictors of acute or chronic adverse effects were identified using multiple logistic regression analyses. RESULTS: Ashtanga yoga (15.7%), traditional Hatha yoga (14.2%), and Sivananda yoga (22.4%) were the most commonly used yoga styles. 364 (21.4%) yoga users reported 702 acute adverse effects, occurring after a mean of 7.6 ± 8.0 years of yoga practice. The most commonly reported yoga practices that were associated with acute adverse effects were hand-, shoulder- and head stands (29.4%). Using Viniyoga was associated with a decreased risk of acute adverse effects; practicing only by self-study without supervision was associated with higher risk. One hundred seventy-three participants (10.2%) reported 239 chronic adverse effects. The risk of chronic adverse effects was higher in participants with chronic illnesses and those practicing only by self-study without supervision. Most reported adverse effects concerned the musculoskeletal system. 76.9% of acute cases, and 51.6% of chronic cases reached full recovery. On average 0.60 injuries (95% confidence interval = 0.51-0.71) per 1000 h of practice were reported, with Power yoga users reporting the highest rate (1.50 injuries per 1000 h; 95% confidence interval = 0.98-3.15). CONCLUSIONS: One in five adult yoga users reported at least one acute adverse effect in their yoga practice, and one in ten reported at least one chronic adverse effect, mainly musculoskeletal effects. Adverse effects were associated with hand-, shoulder- and head stands; and with yoga self-study without supervision. More than three quarters of of cases reached full recovery. Based on the overall injury rate per 1000 practice hours, yoga appears to be as safe or safer when compared to other exercise types.

Several of these species are sources of natural products with biological activities that are still unknown. In this study, we evaluated the antimicrobial activity of 90 extracts derived from native Atlantic Forest tree species against Staphylococcus aureus, an important human and veterinary pathogen. METHODS: Extracts from native Atlantic Forest tree species were evaluated for their antimicrobial activity against S. aureus by in vitro standard methods. Phytochemical fractionation of the extract from Maclura tinctoria was performed by liquid-liquid partitioning. LC-DAD-ESI-MS was used for identification of constituents in the most active fraction. Damage of cells and alterations in the permeability of cell membrane were determined by atomic force microscopy (AFM) and crystal violet uptake assay, respectively. In vivo antimicrobial activity was evaluated using Galleria mellonella larvae infected with S. aureus with survival data collected using the Kaplan-Meier method. RESULTS: Among the organic or aqueous extracts tested here, 26 showed biological activity. Eight species showed relevant results, with a minimum inhibitory concentration (MIC) below 1 mg/mL. Antibacterial activity was registered for three species for the first time. An organic extract from Maclura tinctoria leaves showed the lowest MIC (0.08 mg/mL). Fractionation of this extract by liquid-liquid partitioning led to obtaining fraction 11FO d with a MIC of 0.04 mg/mL. This fraction showed strong activity against veterinary S. aureus isolates and contributed to the increased survival of Galleria mellonella larvae infected with S. aureus ATCC 29213. The bacterial surface was not altered by the presence of 11FO d, and no cell membrane damage was detected. The LC-DAD-ESI/MS analyses identified prenylated flavonoids as the major constituents responsible for the antibacterial activity of this active extract. CONCLUSION: A fraction enriched in prenylated isoflavones and flavanones from M. tinctoria showed in vitro and in vivo efficacy as antistaphylococcal agents. These findings justify the need for further research to elucidate the mechanisms of action of these compounds.

This study further explored the antitumor effects of apiole derivatives AP-02, 04, and 05 in COLO 205 cancer cells. METHODS: Human breast (MDA-MB-231, ZR75), lung (A549, PE089), colon (COLO 205, HT 29), and hepatocellular (Hep G2, Hep 3B) cancer cells were treated with apiole and its derivatives in a dose-dependent manner. Flow cytometry analysis was subsequently performed to determine the mechanism of AP-02-induced G0/G1 cell cycle arrest. The in vivo antitumor effect of AP-02 (1 and 5 mg/kg, administered twice per week) was examined by treating athymic nude mice bearing COLO 205 tumor xenografts. The molecular mechanisms of AP-02-induced antitumor effects were determined using western blot analysis. RESULTS: AP-02 was the most effective compound, especially for inhibition of COLO 205 colon cancer cell growth. The cytotoxicity of AP-02 in normal colon epithelial (FHC) cells was significantly lower than that in other normal cells derived from the breast, lung or liver. Flow cytometry analysis indicated that AP-02-induced G0/G1 cell cycle arrest in COLO 205 cells but not in HT 29 cells (< 5 μM for 24 h, **p < 0.01). Tumor growth volume was also significantly inhibited in AP-02 (> 1 mg/kg)-treated athymic nude mice bearing COLO 205 tumor xenografts compared to control mice (*p < 0.05). Furthermore, G0/G1 phase regulatory proteins (p53 and p21/Cip1) and an invasion suppressor protein (E-cadherin) were significantly upregulated, while cyclin D1 was significantly downregulated, in AP-02-treated tumor tissues compared to the control group (> 1 mg/kg, *p < 0.05). CONCLUSIONS: Our results provide in vitro and in vivo molecular evidence of AP-02-induced anti-proliferative effects on colon cancer, indicating that this compound might have potential clinical applications.

Today, available chemical drugs have shown severe complications during hydatid cyst surgery. Here we investigated theefficacy and safety of Curcuma longa (C. longa) essential oil (CLEO) against hydatid cysts protoscoleces. METHODS: Here, the collected protoscoleces from fertile hydatid cysts were exposed to different concentrations of the CLEO (50-200 μl/mL) for 5-30 min in vitro and ex vivo. In addition, male NIH mice (48 mice) were applied to examine the safety of CLEO. RESULTS: All protoscoleces were completely killed in 5th min of treatment to the doses of 200 μl /mL of CLEO. On the other hand, in the 10th min of treatment, CLEO entirely killed 100% of protoscoleces at the dose of 100 μL/mL. Other doses of CLEO, but, revealed a postponed activity. Although CLEO at the doses of 50, and 100 μL/mL exhibited no similar effect in the ex vivo analysis; but, at the dose of 200 μL/mL and an exposure time of 5 min, approximately 100% of protoscoleces were destroyed into the cyst. We found that after intra-peritoneal injection of the CLEO for 14 days, although blood and biochemical parameters were changed; but there was no significant difference in comparison with the control group (p > 0.05). CONCLUSION: This research demonstrated that C. longa revealed the promising scolicidal effects against protoscoleces in vitro and in vivo, of course, after additional tests; it might be considered as an herbal scolicidal drug in order to decrease the threat of discharge of protoscoleces through hydatid cyst surgery. Nevertheless, supplementary studies will be desired to prove the current findings by examination the essential oil in a clinical setting.

Juglans mollis has been reported as having antioxidant activity, which could attenuate the damage caused by I/R. We evaluated whether a methanolic extract of Juglans mollis (JM) exhibits nephroprotective activity in a Wistar rat model of I/R injury. METHODS: Four groups of six rats were used: Sham, I/R, JM, and JM + I/R. Two groups were dosed with JM (300 mg/kg) for 7 days before I/R. I/R injury was induced by clamping the renal hilums for 45 min and then reperfusing the kidneys for 15 h. Blood samples were taken to evaluate the levels of alanine aminotransferase (ALT), blood urea nitrogen, creatinine, superoxide dismutase (SOD), malondialdehyde (MDA), interleukin 1β (IL-1β), IL-6, and tumor necrosis factor α (TNF-α). RESULTS: The levels of creatinine, ALT, MDA, IL-1β, IL-6, and TNF-α were lower in JM + I/R than in I/R rats, whereas SOD level only was higher in JM + I/R than in Sham rats. No biochemical or histological damage was observed in JM rats compared with Sham rats; however, less histological damage was observed in JM + I/R rats compared with I/R rats. CONCLUSIONS: To our knowledge, this is the first report of nephroprotective activity of J. mollis against damage induced by I/R. This activity may be related to decreased levels of proinflammatory cytokines (IL-1β, IL-6, and TNF-α) and modulation of oxidative stress markers (SOD and MDA) observed in the present study.

There is an urgent need for assessment and evaluation of the antibacterial properties against wound pathogens of honeys that have not yet been tested. METHODS: Ten Saudi honeys collected from different geographical locations were screened initially for their antibacterial potential against methicillin-resistant Staphylococcus aureus (MRSA) and methicillin-sensitive Staphylococcus aureus (MSSA) by the agar well diffusion method. Manuka honey (UMF-12) was used for comparison. Of the tested honeys, the honey that exhibited the greatest antibacterial activity in the agar well diffusion assay was further evaluated for its minimum inhibitory concentration (MIC) against ten MRSA clinical isolates and three American Type Culture Collection (ATCC) reference strains by the microbroth dilution method. RESULTS: Locally produced honeys exhibited variable antibacterial activity against the tested isolates in the agar well diffusion assay. They were unable to exhibit antibacterial activity against MSSA and MRSA at 25% dilutions (w/v) in catalase solution. However, Sumra and Talha honeys showed a zone of inhibition at 50% dilutions (w/v) in catalase solution. This finding means that both honeys possess weak non-peroxide-based antibacterial activity. Moreover, Sumra honey showed a larger inhibition zone at 50 and 25% dilutions (w/v) in distilled water than Manuka honey against both MSSA and MRSA. This result demonstrates that Sumra honey has more hydrogen peroxide-related antibacterial activity or total antibacterial activity than Manuka honey. In addition, MIC results obtained through a microbroth dilution assay showed that Sumra honey inhibited the growth of all MRSA clinical isolates (n = 10) and reference strains [MRSA (ATCC 43300) and MSSA (ATCC 29213)] at lower concentrations (12.0% v/v) than those required for Manuka honey-mediated inhibition (14.0% v/v). This result means that Sumra honey has more peroxide or synergistic antibacterial activity than Manuka honey. An equivalent MIC (15.0% v/v) was observed for E. coli (ATCC 25922) between Manuka honey and Sumra honey. CONCLUSIONS: Sumra honey may be used as an alternative therapeutic agent for infected wounds and burns, where additional hydrogen peroxide-related antibacterial activity is needed. In the future, the physiochemical characteristics of Sumra honey may be evaluated and standardized.

The beneficial effect of Momordica charantia on heart has been reported by in vitro and in vivo studies. However the developmental toxicity or potential risk of M. charantia on fetus heart development is largely unknown. Hence this study was designed to find out the developmental toxicity of M. charantia using zebrafish (Danio rerio) embryos. METHODS: The crude extracts were prepared from fruit and seeds of M. charantia. The Zebrafish embryos were exposed to serial dilution of each of the crude extract. The biologically active fractions were fractionated by C18 column using high pressure liquid chromatography. Fourier-transform infrared spectroscopy and gas chromatography coupled with mass spectrophotometry was done to identify chemical constituents in fruit and seed extract of M. charantia. RESULTS: The seed extract of M. charantia was lethal with LD values of 50 μg/ml to zebrafish embryos and multiple anomalies were observed in zebrafish embryos at sub-lethal concentration. However, the fruit extract was much safe and exposing the zebrafish embryos even to 200 μg/ml did not result any lethality. The fruit extract induced severe cardiac hypertrophy in treated embryos. The time window treatment showed that M. charantia perturbed the cardiac myoblast specification process in treated zebrafish embryos. The Fourier-transform infrared spectroscopy analyses revealed diverse chemical group in the active fruit fraction and five new type of compounds were identified in the crude seeds extract of M. charantia by gas chromatography and mass spectrophotometry. CONCLUSION: The teratogenicity of seeds extract and cardiac toxicity by the fruit extract of M. charantia warned that the supplementation made from the fruit and seeds of M. charantia should be used with much care in pregnant diabetic patients to avoid possible damage to developing fetus.

Its extracts showed potent in vitro antibacterial activity. However, the antibacterial components are unknown. METHODS: In this study, the stem bark of the CG plant was extracted and its antibacterial property against a panel of Gram-negative and Gram-positive bacterial strains assessed using the disk diffusion assay method. Bioassay-guided fractionation of the bioactive extracts was employed to identify bioactive constituents using both gas and liquid chromatography mass spectrometry. Chemical synthesis was used to make the analogues of gallic acid. Microplate dilution assays and scanning electron microscopy (SEM) were used to evaluate the antibacterial properties and mechanism of action of the active fractions and pure compounds. RESULTS: The most bioactive sub-fractions derived from CG comprised of ethyl gallate, gallic acid and polyphenols. Five alkyl/alkenyl gallates were synthesized. A preliminary structure-activity relationship of gallic acid derivatives was obtained using the synthetic analogues and a series of commercially available phenolic compounds. Increasing the length of alkyl chains generally increases the potency of the alkyl gallates. Introducing a double bond with restricted conformations of the C-5 side chain has little effect on the antibacterial property. SEM analysis of the effect of alkyl gallates on Staphylococcus aureus indicates that they appear to interrupt S. aureus bacterial cell wall integrity. CONCLUSIONS: The results of this research rationalise the ethnobotanical use of C. gabunensis and suggest that gallate derivatives may serve as promising antibacterial agents for the treatment of infectious diseases.

So, the aim of this work was to propagate Lunularia cruciata under in vitro condition for comparing its pharmacological properties and phytocmecial constituents with naturally grown counterparts. METHOD: Axenic culture of L. cruciata was established by propagating gemmae under in vitro condition. Appropriate culture conditions, media, and the effect of hormones on growth and development were studied. The phytochemical composition was determined by GC-MS analysis and pharmacological activity was evaluated by assessing the antioxidant and anti-diabetic activities. For the antioxidant activity ABTS [2,2'-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid)], DPPH (2,2-diphenyl-1-picrylhydrazyl) and metal chelating assays were done and for evaluation of the in vitro anti-diabetic activity α-glucosidase and α-amylase inhibitory activities were done. RESULT: Growth of L. cruciata was recorded in half strength MS media. Benzylaminopurine (BAP: 2 mg/L) and 1-Naphtheleneacetic acid (NAA: 0.5 mg/L) were the successful hormonal combination. GC-MS analysis revealed the existence of nine key compounds in both in vitro and naturally grown L. cruciata. Result of antioxidant and anti-diabetic activity showed that in vitro grown L. cruciata has a more or less similar antioxidant and anti-diabetic activities as naturally grown ones. This result confirms the possibility of using in vitro grown plants in place of naturally grown plants for research and clinical purposes.

Acacia hydaspica is a natural shrub with diverse bioactivities. Acacia hydaspica ethyl acetate extract (AHE) ameliorated drug-induced cardiotoxicity in animals with anti-oxidative mechanisms. Current study aimed to evaluate the protective potential of A. hydaspica against cisplatin-induced myocardial injury. METHODS: Rats were indiscriminately distributed into six groups (n = 6). Group 1: control; Groups 2: Injected with CP (7.5 mg/kg bw, i.p, single dose) on day 16; Group 3: Treated for 21 days with AHE (400 mg/kg b.w, oral); Group 4: Received CP injection on day 16 and treated with AHE for 5 days post injection; Group 5: Received AHE (400 mg/kg b.w/day, p.o.) for 21 days and CP (7.5 mg/kg b.w., i.p.) on day 16; Group 6: Treated with silymarin (100 mg/kg b.w., p.o.) after 1 day interval for 21 days and CP injection (7.5 mg/kg b.w., i.p.) on day 16. On 22nd day, the animals were sacrificed and their heart tissues were removed. Cisplatin induced cardiac toxicity and the influence of AHE were evaluated by examination of serum cardiac function markers, cardiac tissue antioxidant enzymes, oxidative stress markers and histology. RESULTS: CP inoculation considerably altered cardiac function biomarkers in serum and diminished the antioxidant enzymes levels, while increased oxidative stress biomarkers in cardiac tissues AHE treatment attenuated CP-induced deteriorations in creatine kinase (CK), Creatine kinase isoenzymes MB (CK-MB), cardiac Troponin I (cTNI) and lactate dehydrogenase (LDH) levels and ameliorated cardiac oxidative stress markers as evidenced by decreasing lipid peroxidation, HO and NO content along with augmentation in phase I and phase II antioxidant enzymes. Additionally, CP inoculation also induced morphological alterations which were ameliorated by AHE. In pretreatment group more significant protection was observed compared to post-treatment group indicating preventive potential of AHE. The protective potency of AHE was comparable to silymarin. CONCLUSION: Results demonstrate that AHE attenuated CP induce cardiotoxicity. The polyphenolic metabolites and antioxidant properties of AHE might be responsible for its protective influence.

The aim of the study was to individually probe the profile of methanol extracts from three different parts of Zanthoxylum armatum. METHODS: The ex-vivo muscle relaxant effects of extracts were assessed in the isolated intestine, trachea and thoracic aortic rings and were compared with the positive controls and CRC were constructed. The anti-diarrheal effect of extracts was evaluated in mice by inducing diarrhea with castor oil. The extracts were also studied for acute toxicity and butyrylcholine esterase inhibition. RESULTS: The extracts from fruit, bark and leaves of Z. armatum showed inhibitory effect against the butyrylcholine esterase enzyme with percent inhibition of 50.75 ± 1.23, 82.57 ± 1.33, and 37.52 ± 1.11respectively, compared to standard serine (IC: 0.04 ± 0.001 μmol/L). The fruit and bark extracts provided 75, and 52% diarrheal protection, compared to verapamil (96%). In isolated rabbit jejunum strips, increasing addition of the extracts inhibited the spontaneous and high K precontractions with EC values of 0.71 and 3 mg/mL for fruit, EC values of 0.61 and 0.5 mg/mL for bark, EC 0.81 and 3.1 mg/mL for leaves, like verapamil. The extracts induced a concentration-dependent relaxation of the carbachol (1 μM) and high K (80 mM) precontractions with EC values of 2.4 and 0.9 mg/mL for fruit, EC values of 1.2 and 3 for leaves. The bark extract was equipotent against both contractions with EC 3.1 and 0.7 mg/mL, respectively. In the aortic rings, the fruit extract completely relaxed the phenylephrine (1 μM)-induced contractions with (EC value = 0.8 mg/ml) and a partial inhibition of high K induced contractions. The leaves extract completely relaxed the aortic contractions with (EC values = 1.0 and 8.5 mg/ml). The extracts caused no acute toxicity up to 3 g/kg dose. CONCLUSIONS: The experiments revealed that the extracts of aerial parts of Z. armatum have antidiarrheal properties in vivo and showed spasmolytic effect in intestinal and tracheal preparations with possible mechanism involving the blockage of Ca channels. These experiments provide enough justification for use of this plant in ethnomedicine in diarrhea, gut and bronchial spasms.

METHODS: We performed comprehensive searches on Embase, Pubmed, Cochrane Library, CNKI, VIP and Wanfang databases up to June 2017 for randomized controlled trials using HXHY in the treatment of NAFLD compared with conventional treatment. RESULTS: This meta-analysis included 13 studies involving 1429 patients which 775 patients belonged to HXHY group and 654 patients belonged to conventional treatment group. The results of meta-analysis showed that HXHY can significantly improve B ultrasonic level (OR = 2.33; 95% CI:1.60, 3.40; P < 0.00001) of NAFLD compared with conventional treatment. As to lipids, HXHY was tested to be better on reduction of total cholesterol (TC) (MD = -0.38, 95% CI: - 0.48, - 0.29; P < 0.00001) and triglyceride (TG) (MD = -0.31; 95% CI: - 0.37, - 0.24; P < 0.00001) than conventional treatment. HXHY also had a greater beneficial effect on liver function in reducing alanine transaminase (ALT) (MD = -1.69; 95% CI: - 2.24, - 1.14; P < 0.00001) and aspartate transaminase (AST) (MD = -22.53; 95% CI: - 33.16, - 11.90; P < 0.00001) compared with conventional treatment. HXHY can also significantly improve the effective rate (OR = 3.55; 95% CI:2.65, 4.76; P < 0.00001) compared with conventional treatment. No serious adverse reactions were reported. CONCLUSIONS: HXHY seems to be an effective and safe therapy for NAFLD. It is suggested that further study of HXHY in the treatment of NAFLD requires trials with rigorous design, multicenter, large-scale and high-quality worldwide.

Patient safety is a concern, as DS-drug interactions and adverse events are potential complications. Since many persons with dementia buy their DS in pharmacies, we investigated Norwegian pharmacy employees' attitudes and professional practice behaviors related to DS. METHODS: We conducted a survey in eight Norwegian municipalities of pharmacy employees involved in the sale of DS. The questionnaire covered demographics and investigated attitudes toward DS, professional practice behaviors related to the sale of DS, experiences with customers with dementia, and perceived and attributed responsibilities with regard to patient safety. RESULTS: One hundred and five employees responded (response rate: 52%). Most employees regarded general practitioners (GPs) as primarily responsible for safeguarding the use of DS by persons with dementia and rated themselves less responsible. Thirty-seven percent of the employees reported personal use of DS (past or current use). Nine percent considered some of the DS to have symptomatic or prophylactic effects against dementia. Forty-eight percent confirmed that they informed customers about potential adverse events; 42% indicated that they did this sometimes. Sixteen percent checked regularly for DS-drug interactions, and two-thirds checked depending on the customers' health, the type of drug or the type of DS. One-quarter regularly asked about the co-use of prescription drugs (PD) when selling DS, while only 2% asked about the co-use of DS when dispensing PD. Only 25% reported access to independent scientific information on all or most DS sold in their pharmacy. Eight percent had experienced unsafe use of DS by persons with dementia. Six percent had been taught about counselling persons with dementia. Education level influenced professional practice behavior to some extent. CONCLUSION: Pharmacy employees do not see themselves as primarily responsible for the safe use of DS by persons with dementia. Moreover, they have limited experience with the unsafe use of DS by these persons. There is potential for improvement regarding tools and educational interventions for pharmacy employees to provide sufficient help to persons with dementia who use DS.

The current investigation is focused on the action of extracts of Quercus infectoria gall in their sub-inhibitory concentrations on the corresponding bacterial behaviours instead of killing them. METHODS: The effect of gall extracts on the quorum sensing (QS) associated virulence of multiple drug resistant Pseudomonas aeruginosa recovered from burns wounds was studied. The influence of different extracts on the production of bacterial virulence and biofilm, and expression of the genes encoding quorum sensing and exotoxin A were investigated. Quorum sensing is a crucial regulator of virulence and biofilm development in Pseudomonas aeruginosa and other medical related microbes. RESULTS: Experiments to characterise and quantify Q. infectoria gall extracts impact on the quorum sensing networks of P.aeruginosa revealed that the expression of las, rhl, and exotoxin A (ETA) genes levels including the associated virulence were reduced by the extracts at their subinhibitory concentrations. CONCLUSIONS: The obtained results indicated that extracts of Q. infectoria galls fight infections either by their inhibitory constituents, which vigorously eradicate cells or by disruption of the pathogens quorum sensing system through weakening the virulence and bacterial coordination.

The aim of this work was to investigate the effect of the extract from Agkistrodon halys venom on lipopolysaccharide (LPS)-induced myocardial injury. METHODS: Thirty male Sprague-Dawley rats were randomly assigned to three groups (10 rats per group): control group, LPS group and LPS + extract group. Rats in control and the LPS groups were intravenously injected with sterile saline solution, and rats in the LPS + extract group with the extract. After 2 h, rats of the control group were intraperitoneally injected sterile saline solution, and rats in the LPS and the LPS + extract groups were treated with LPS (20 mg per kg body weight). Levels of creatine kinase (CK) and lactate dehydrogenase (LDH) in serum were determined. Anti-inflammation of the extract was analyzed via determination of TNF-α and IL-6 in serum, and expression of TNF-α, IL-6, COX-2 and p-ERK protein in hearts. Heme oxygenase-1 (HO-1) and p-NF-κB protein expression in hearts, superoxide dismutase (SOD) activity and malondialdehyde (MDA) level in serum were used to evaluate the anti-oxidative properties of the extract. RESULTS: Extract pretreatment significantly decreased the level of serum CK and LDH, reduced the generation of inflammatory cytokines such as TNF-α and IL-6, and also reduced serum level of MDA in the LPS + extract group compared with the LPS group. In addition, the extract increased SOD activity in serum, HO-1 protein expression in hearts, and decreased TNF-α, IL-6, COX-2, p-NF-κB and p-ERK1/2 protein expression. CONCLUSION: Our results suggested that beneficial effect of this extract might be associated with an improved anti-oxidation and anti-inflammatory effect via downregulation of NF-κB/COX-2 signaling by activating HO-1/CO in hearts.

In recent years, with the increasing morbidity of diseases such as diabetes and metabolic disorders, chronic wounds have become a considerable challenge in clinical practice. Royal jelly, reported to have multifarious biological and physiological properties, has been used as a remedy for a variety of wounds since ancient times. However, the active components and mechanisms underlying the wound-healing properties of royal jelly are still largely unknown. METHODS: Water-soluble proteins of royal jelly were fractionated and investigated for the proliferative and migratory effects on human epidermal keratinocytes (HaCaT) in an in vitro wound healing model. The proteins present in bioactive fractions were characterised and quantified using Label-free protein quantification method. The potential functions of these proteins in biological systems were further analysed using bioinformatic tools. RESULTS: A protein fraction, mainly containing major royal jelly proteins 2 (MRJP2), MRJP3 and MRJP7, stimulated proliferative and migratory activities in HaCaT cells without visible cytotoxicity. It exerted the greatest effects on the growth of HaCaT cells in the first 48 h. Furthermore, when treated with this protein fraction, the closure rates of the in vitro scratch wound were significantly increased. Functional analysis indicated that MRJP2, MRJP3 and MRJP7 were associated with carbohydrate transport and metabolism. CONCLUSIONS: We fractionated the water-soluble proteins of royal jelly and identified one fraction (Fraction 2) that induced both proliferative and migratory effects on a human epidermal keratinocyte cell line. Major royal jelly proteins (MRJP2, MRJP3 and/or MRJP7) were speculated to possess potential wound-healing bioactivity. This is the first report that royal jelly may improve wound closure via MRJP-induced cellular proliferation and migration. These proteins may be valuable lead compounds for the development of novel wound healing medications. Our findings would facilitate better understanding of the wound repair mechanisms of royal jelly.
