BACKGROUND: Clinical and epidemiological data well defines the role of atherosclerotic risk factors in pathogenesis of aortic stenosis. Especially dyslipidemia with elevated total and LDL cholesterol levels exerts certain histopathological changes on calcified valve tissue. Exact role of HDL in this process is not known. OBJECTIVE: To evaluate the lipid profiles of patients with mild aortic valve stenosis with special focus on HDL; HDL subspecies, serum apoA1 levels, HDL related PON1 and PAF-AH enzyme activities and to correlate this with disease progression rates. METHOD: 42 patients (26 female; 16 male), with calcific aortic valve stenosis were enrolled in the study. Serum fasting lipid parameters, HDL subspecies (HDL2, HDL3), serum apoA1 levels and HDL related PON1 and PAF-AH enzyme activities were determined. All participants underwent detailed follow-up transthoracic echocardiography examination. RESULTS: Among 42 study participants mean serum total cholesterol level was 195 ± 27.3 mg/dl, LDL-c level was 123 ± 19.1 mg/dl, HDL-c level was 44 ± 10.3 mg/dl and total cholesterol/HDL-c ratio was 4.64 ± 1.13. Basal peak aortic jet velocity (Vmax2) was 2.67 ± 0.39 m/sec, mean pressure gradient (Pmean2) was 15.6 ± 5.5 mmhg. Annual progression rate in peak aortic jet velocity (Vmax) was 0.23 ± 0.17 m/sec, in mean pressure gradient (Pmean) was 3 ± 2.1 mmhg. Annual progression rate in Pmean was most strongly correlated with serum HDL-c level and total/HDL-c ratio (r=-0.528 and 0.505; <0.001 and 0.001 respectively). Progression in Vmax values was positively correlated with serum LDL-c level and total/HDL-c ratio while negatively correlated with serum HDL-c levels (r=0.328, 0.499 and -0.464; P=0.034, 0.001 and 0.002 respectively). Among HDL subspecies HDL2 was the predominant type. HDL2 levels were found to be positively correlated with progression rates. There was no significant correlation between apolipoprotein A1 level and annual progression rate. Serum PON1 activity level was determined to be negatively correlated to doppler echocardiographic progression parameters while HDL related PAF-AH activity was independent of disease progression. CONCLUSION: Present study demonstrated a positive correlation between disease progression and serum total cholesterol/HDL-c ratio. Serum HDL-c level was inversely correlated with hemodynamic progression. The majority of HDL was HDL2 subtype. Among HDL related enzymes PON1 enzyme activity exhibited an inverse correlation with disease progression.

This review aimed to summarize the epidemiology (incidence, prevalence and morality) and risk factors of inflammatory bowel disease (IBD). IBD is a chronic, relapsing, inflammatory disorder of the gastrointestinal tract and includes Crohn's Disease (CD) and ulcerative colitis (UC). IBD has increasing incidence and prevalence in most of countries and becomes a global emerging disease. A westernized lifestyle or habits and some environmental factors have been found to contribute to the pathogenesis of IBD. The relevant risk factors include Smoking, hygiene hypothesis, microorganisms, appendectomy, medication, nutrition, and stress have all been found to be associated with the modality of IBD, but results are inconsistent on this issue in available studies. Therefore, more studies are required to identify and understand the environmental determinants of IBD.

OBJECTIVE: To evaluate the relationship between BRAF mutation and factors influencing the prognosis of papillary thyroid microcarcinoma (PTMC). METHODS: Clinical data from patients with PTMC were subjected to retrospective analysis. A total of 86 patients were included, and the BRAF(V600E) mutation was identified in surgically dissected tissues. RESULTS: The incidence of BRAF mutation in patients with PTMC was 65.1% (56/86). Both univariate and multivariate analyses indicated a correlation between BRAF mutation and lymph node metastasis (P = 0.057). For patients with tumors ≤ 10 mm in diameter, BRAF mutation had no effect on lymph node metastasis (P > 0.05). No lymph node metastasis was found in patients with tumors ≤ 5 mm in diameter. CONCLUSION: BRAF gene mutation is an independent predictive risk factor for central lymph node metastasis in patients with PTMC. For patients with preoperative BRAF mutation positivity, it is important to perform central lymph node dissection (CLND) and lymphatic and adipose tissues should be routinely removed. However, in patients without BRAF mutation and tumors ≤ 5 mm in diameter, the necessity of prophylactic CLND should be reevaluated.

PURPOSE: To explore the role of serum interleukin-16 (IL-16) in the occurrence of multiple myeloma (MM) and after the success chemotherapy and its clinical significance. METHODS: 52 cases of MM patients, 30 cases of AML patients and 30 healthy volunteers from Jan. 2011 to Jan. 2015 were collected in this study. There was 39 MM patients received chemotherapy. Among those, 24 patients received VAD regimen chemotherapy and 15 patients received BD regimen chemotherapy. Serum IL-16, cystatin C (Cys-C), lactate dehydrogenase (LDH) and levels of β2-microglobulin (β2-MG) were detected before and after the therapy of MM patients. And those results were compared to that of patients with acute myelogenous leukemia (AML) and normal people respectively. RESULTS: The levels of serum IL-16, Cys-C, LDH and β2-MG in MM group were remarkably higher than that of normal control. It was of statistical significance of this difference (P<0.05). Levels of serum IL-16, Cys-C and LDH of MM patients who received therapy were all lower than that of patients before therapy. The serum IL-16 and β2-MG of 52 patients by preliminary diagnosis were analyzed through Pearson correlation analysis before they received therapy. The results showed that there was positive correlation between levels of IL-16 and β2-MG (r=0.782, P<0.01). CONCLUSIONS: A high serum IL-16 level detected in newly diagnosed MM patients and its correlation with known factors of disease activity as well as the decrease of IL-16 after chemotherapy suggest that IL-16 may be implicated and a potential therapeutic target for MM.

INTRODUCTION: Acquired erythroblastopenia (AE) is a rare clinical situation. It is characterized by the reduction of erythroid precursors in the bone marrow together with the low reticulocyte counts in the peripheral blood. BACKGROUND: Main secondary causes of AE are drugs, Parvovirus B19 and other infectious reasons, lymphoid and myeloid neoplasia, autoimmune diseases, thymoma and pregnancy. The aim of this study is to assess the frequencies and clinical associations of AE via analyzing 12340 bone marrow samples in a retrospective manner. MATERIAL AND METHOD: Bone marrow aspirations which were obtained from patients who applied to Hacettepe University Hematology Clinic between 2002 and 2013, were analyzed retrospectively. RESULTS: Thirty four erythroblastopenia cases were found. Patients ranged in age from 16 to 80 years with a median of 38 years. Fifteen patients were men (44%) and nineteen were women (56%). In these patients, detected causes of erythroblastopenia were MDS, idiopathic pure red cell aplasia (PRCA), parvovirus infection, post chemotherapy aplasia, plasma proliferative diseases, copper deficiency due to secondary amyloidosis, fever of unknown origin, hemophagocytic syndrome, enteric fever and legionella pneumonia. We found that between those reasons the most common causes of erythroblastopenia are MDS (17.7%) and idiopathic PRCA (17.7%). DISCUSSION: As a result, erythroblastopenia in the bone marrow may be an early sign of MDS. In those AE cases possibility of being MDS must be kept in mind as it can be mistaken for PRCA. CONCLUSION: To conclude, in adults MDS without excess blast is one of the most common causes of erythroblastopenia in clinical practice and in case of erythroblastopenia the presence of MDS should be investigated.

BACKGROUND: Giant cell tumor of bone (GCTB) is a relatively rare tumor of bone, characterized by numerous multinucleated cells, severe osteolysis, and local recurrence. PURPOSE: To explore the role of S-phase kinase-interacting protein 2 (Skp2), cyclin-dependent kinase inhibitor p27, and the transcription factor E2F-1 expression in the development of GCTB, and the relationship of expression of these proteins with tumor recurrence. METHODS: Forty-four patients with GCTB were selected and demographic and clinical data were collected. The levels of Skp2, p27, and E2F-1 protein expression were immunohistochemically assessed in surgical specimens. RESULTS: Skp2, p27, and E2F-1 proteins were detected in the nuclei of mononuclear stromal cells. Positive Skp2 expression was observed in 66% (29/44) of GCTB patient samples, and positive p27 expression was found in 39% (17/44) of samples. Within almost all GCTB patients, there was an inverse correlation between Skp2- and p27-positive tumor cells. Positive expression of E2F-1 was present in 28 of 44 (64%) patients. In addition, expression of skp2 and p27, infiltration of soft tissues, and surgical operation were significantly associated with recurrence in patients with GCTB. CONCLUSION: The immunohistochemical assessment of Skp2, p27 and E2F-1 may be useful in the diagnosis of GCTB and prediction of its prognosis.

We aimed to evaluate the association of rs964184 of BUD13-ZNF259 gene with the risk of hemorrhagic stroke (HS). A total of 138 HS cases and 587 controls were recruited for the association of rs964184 of BUD13-ZNF259 gene with the risk of HS. Tm shift PCR was used for genotyping. We were unable to find the association of rs964184 of BUD13-ZNF259 gene with the risk of HS (P>0.05). Significant difference was found in the TG level among the three genotypes (CC: 1.51±1.02; CG: 1.68±1.10; GG: 1.90±1.11, P=0.036). The TG level showed strong correlation with rs964184 genotypes (P=0.010, correlation=0.101). Significantly higher TC, HDL-C, and LDL-C levels were observed in the case group. And no difference was found in the TG, ApoA-I, ApoB. Our case-control study supported the significant association between rs964184 genotype and the blood TG concentration, although we were unable to find association between BUD13-ZNF259 rs964184 and the risk of HS in Han Chinese.

Diffuse large B-cell lymphoma (DLBCL) is the most frequent type of non-Hodgkin's lymphoma (NHL) in adults, and approximately 50% of cases of DLBCL occur in patients above the age of 60. Although RCHOP regimen was established as the standard therapy for DLBCL patients, there are still a large number of DLBCL patients who can't bear the toxicity of doxorubicin, especially in elderly patients. Pegylated liposomal doxorubicin (PLD) offers a new strategy for elderly DLBCL patients. In our study, we reviewed 103 newly diagnosed patients with DLBCL aged between 60 years to 75 years old who were treated with RCHOP (62 cases) or DRCOP (41 cases) regimen. All the patients completed a mean follow-up period of 28 months (range, 2 to 48 months). There was no statistical difference of OS between the DRCOP (78.0%) and RCHOP (72.6%) groups (P = 0.787). And there were less grade 3-4 cardiotoxicity in patients treated with DRCOP (9.8%) than RCHOP regimen (27.4%, P = 0.029). Our findings in this study indicate that the DRCOP regimen offers similar oncologic efficacy when weighed against the standard RCHOP regimen in elderly DLBCL patients, and it might be a more secure treatment for elderly DLBCL patients who have additional risk factors for cardiac diseases.

INTRODUCTION: Sexual dysfunction and vitamin D deficiency are highly prevalent in dialysis patients. Low levels of vitamin D have been linked to many diseases. To the best of our knowledge, the relationship between vitamin D and sexual dysfunction in dialysis patients has not been previously reported in the literature. MATERIALS AND METHODS: Cholecalciferol, 50,000 IU/week, was orally administered to 37 dialysis patients with vitamin D insufficiency for 3 months followed by dosage of 10,000 IU every other week for 3 months. The Arizona Sexual Experiences Scale (ASEX), Hospital Anxiety and Depression Scale and Pittsburgh Sleep Quality Index questionnaires were filled out by all patients at baseline and at the sixth month of the study. RESULTS: Sexual dysfunction, poor sleep quality, anxiety and depression rates were 83.7%, 45.9%, 18.9% and 48.6%, respectively in all patients. ASEX total score was found to be positively correlated with age and was negatively correlated with serum 25(OH)D level and serum albumin level. After cholecalciferol treatment, 25(OH)D levels increased significantly, however no significant change was observed in any of the parameters. In multivariate linear regression analysis, age and 25(OH)D level were found to be independent predictors of ASEX total score. CONCLUSIONS: Vitamin D deficiency seems to contribute to sexual dysfunction in dialysis patients. However, it was observed in this study that; cholecalciferol replacement given to dialysis patients with vitamin D insufficiency did not result in any significant changes in sexual functions.

BACKGROUND: Anterior cruciate ligament (ACL) rupture is the most common ligamentous injury for active adolescents and young adults each year. However, the precise etiologies of ACL injury are not fully understood. The present study was to investigate +104T/C polymorphism of growth differentiation factor 5 (GDF5) gene in patients with ACL rupture, and evaluate the effects of polymorphism on GDF5 mRNA levels in ligament of patients with ACL rupture in central China. METHODS: A total of 286 Chinese patients with ACL rupture and 500healthy controls were enrolled in this study. The +104T/C polymorphism in GDF5 gene were genotyped by DNA sequencing. GDF5 mRNA expressions levels in ligament were determined by quantitative PCR. RESULTS: The frequency of the TT genotype tended to be higher in ACL rupture group than in control group (62.6% vs. 48.0%, P< 0.001, OR = 1.81, 95% CI: 1.35-2.44). T allele of the GDF5 +104T/C polymorphism was more common in ACL rupture group than in control group (P< 0.001). Patients carrying TT genotype expressed lower levels of GDF5 mRNA than C carriers (P = 0.005) among ACL rupture. CONCLUSION: Our study indicated that GDF5 +104T/C polymorphism was associated with ACL rupture patients in central China. This is likely from decreased expressions of GDF5 mRNA. Further studies are necessary to explore the functional implication of the GDF5 +104T/C polymorphism in Chinese ACL rupture patients.

Nonalcoholic steatohepatitis (NASH) is currently one of the primary liver diseases. Recent studies have shown a clinical relation between NASH and atherosclerosis. There is much interest in these two diseases because they are both associated with great morbidity and mortality. Inflammation and the overexpression of COX-2 participate in the pathophysiology of the two diseases, and therefore simultaneous treatment is feasible. The role of the four NSAIDs, meclofenamate, mefenamate, flufenamate, and aspirin, was analyzed in a mouse model of NASH, as well as preclinical atherosclerosis induced by a high-fat diet (HFD). Six mouse groups were formed. Five of the groups were fed a high-fat diet for 6 months and one group was fed a standard diet, acting as the normality reference. Of the five groups fed a high-fat diet, four received a NSAID, each of them identified by the specific drug administered. One group received no treatment. Serum markers (cholesterol, triglycerides, ALT, and AST) and histologic changes in the aorta and liver were analyzed for the study. Aspirin significantly reduced the hepaticsteatosis. All the drugs significantly reduced the hepatic inflammatory infiltrate. In relation to atherosclerosis, there were significant reductions in all the study variables with the use of aspirin and flufenamate. The four medications were able to stop steatosis from progressing into steatohepatitis by reducing inflammation. However, aspirin was the most beneficial, simultaneously reducing steatosis, atherosclerosis, and serum cholesterol levels.

The Chronic kidney disease (CKD) is characterized by the progressive loss in renal function over a period. The progression of CKD will finally result the End Stage Renal Disease (ESRD) Symptoms which needs permanent renal replacement therapies. Therefore, control the progression of CKD is necessary. In this study, based on the theory of Traditional Chinese Medicine and the Traditional Chinese Herbology, we developed the Kangshen Oral Solution based ona combination of different herbs for extraction. By utilizing adriamycin (ARD)-induced chronic renal failure in rats as the CKD model, our results demonstrated thatadministration of the Kangshen Oral Solution reduced the kidney disease induced weight loss in rats. The Kangshen Oral Solution could also relieve the proteinuria and kidney index induced by ARD which indicated the partially restoration of the kidney function. The improved kidney function was further supported by biochemical tests for blood total protein level, albumin level as well as cholesterol, triglycerides and Creatinine. Moreover, the histology examination also confirmed the ARD induced pathological changes in kidney was relieved by Kangshen Oral Solution. Taken together, these findings suggested Kangshen Oral solution could reduce ARD-induced nephropathy in rats model and may be employed as an alternative treatment for CKD patients.

Postoperative pain is the main obstacle for safely rapid recovery of patients undergoing laparoscopic cholecystectomy (LC). In this study, we systemically evaluated the analgesic efficacy of intraperitoneal and incisional ropivacaine injected at the end of the LC. A total of 160 patients, scheduled for elective LC, were allocated into four groups. Group Sham received intraperitoneal and incisional normal saline (NS). Group IC received incisional ropivacaine and intraperitoneal NS. Group IP received incisional NS and intraperitoneal ropivacaine. Group ICP received intraperitoneal and incisional ropivacaine. At the end of the surgery, ropivacaine was injected into the surgical bed through the right subcostal port and infiltrated at the four ports. Dynamic pain by a visual analogue scale (VAS) and cumulative morphine consumption at 2 h, 6 h, 24 h, and 48 h postoperatively, as well as incidence of side-effects over 48 h after LC was recorded. Compared with those in group Sham, the time of post-anesthesia care unit (PACU) stay, dynamic VAS score (VAS-D) 2 h and 6 h postoperatively, cumulative morphine consumption 6 h and 24 h postoperatively, and incidence of nausea and vomiting 48 h after LC in group IC and ICP were less (P<0.05). Furthermore, intraperitoneal and incisional ropivacaine exerts more powerful analgesic effect than single usage with intraperitoneal or incisional ropivacaine (P<0.05). No patients exhibited signs of local anesthetic toxicity. In conclusion, intraperitoneal and incisional ropivacaine might facilitate PACU transfer and effectively and safely reduce pain intensity after LC.

AIMS: To investigate how specific factors, including knowledge, attitude, use of protective devices, safety climate, workload, and nurses' behaviors can influence standard precautions in China through structural equation modeling techniques. BACKGROUND: Although a number of empirical studies have been conducted, an investigation of how multiple variables influence behaviors of standard precautions among the nurses is still needed. METHODS: The study was conducted by selecting registered nurses from 25 public hospitals that operate approximately 500 beds located in different areas of Guizhou Province in China. An anonymous, self-administered questionnaire was distributed to 1000 nurses, and 964 (96.4%) completed questionnaires were returned. exploratory factor analysis was employed to examine associations of attitudes, protective devices, safety climate, workload, and nurses' behaviors with standard precautions. The identified factors were integrated in the proposed structural equation model. FINDINGS: Protective devices had a positive and major influence on nurses' use of standard precautions. Knowledge had a positive impact on the use of standard precautions through attitude mediation, and the safety climate had a positive impact on the use of standard precautions. In contrast, increasing workload had a negative effect on the use of standard precautions. The factors affecting the use of standard precautions among nurses in order of decreasing effect size were: protective devices, knowledge, attitude, safety climate, and workload. CONCLUSIONS: This study offer valuable information for healthcare management regarding the use of standard precautions to reduce occupational exposure among nurses.

The objective of this study was to determine the combination of left ventricular ejection fraction (LVEF) and individual electrocardiographic parameters related to abnormal depolarization/repolarization or baroreceptor sensitivity that had the best predictive value for major adverse cardiac events (MACE) in patients with acute coronary syndrome (ACS). Patients with ACS who underwent coronary angiography and percutaneous coronary intervention (PCI) were included in this prospective study. Ventricular late potential (VLP), heart rate turbulence (HRT), heart rate variability (HRV), and T wave alternans (TWA) parameters were measured using 24 h Holter monitoring 2-4 weeks after onset of ACS. Initial and follow-up LVEF was measured by ultrasound. Patients were followed for at least 6 months to record the occurrence of MACE. Models using combinations of the individual independent prognostic factors found by multivariate analysis were then constructed to use for estimation of risk of MACE. In multivariate analysis, VLP measured as QRS duration, HRV measured as standard deviation of normal RR intervals, and followup LVEF, but none of the other parameters studied, were independent risk factors for MACE. Areas under ROC curve (AUCs) for combinations of 2 or all 3 factors ranged from 0.73 to 0.76. Combinations of any of the three independent risk factors for MACE in ACS patients with PCI improved prediction and, because these risk factors were obtained non-invasively, may have future clinical usefulness.

OBJECTIVES: Congenital cataract is the common cause of world blindness. It is generally inherited as an autosomal recessive trait and has various phenotypes. This study aimed to explore the gene responsible for autosomal recessive congenital cataract in a Chinese family, and to investigate the functional and cellular consequences of the mutation. METHODS: A four-generation Chinese family with autosomal recessive congenital cataract was included in the study. A genome wide scan and linkage analysis were performed in the chromosomal region of Pituitary homeobox 3 (PITX3) to identify the linked region of the genome. And sequence analysis of PITX3 gene was also investigated using BigDye Terminator mix 3.0 and SeqScape Software 2.5. RESULTS: The genome wide scan and linkage analysis identified a disease-haplotype interva. The maximum logarithm of odds LOD score was (Zmax) 3.11 at marker D10S1693 (θmax=0.00), flanked by D10S1680 and D10S467, which included the PITX3 gene. Sequencing revealed a splice site mutation, G→A, at D10S1680 and D10S467, which co-segregated with all the affected members of this family. CONCLUSIONS: The 543delG is a novel mutation in PITX3 causing an autosomal recessive congenital cataract.

Acute promyelocytic leukemia (APL) is a common myeloid leukemia. At the newly diagnosed stage, it can be fatal because of the serious complication-disseminated intravascular coagulation. With the advent and early application of all-trans retinoic acid, most APL patients can achieve a long-term survival, and only a minority of patients will develop extramedullary relapse after remission. The most common site of extramedullary relapse is central nervous system, while other sites are relatively rare. Here, we report a particularly rare APL patient who experienced extramedullary relapse with lumbar spine as the isolated site after a rather long time of remission for 16 years. At the time of relapse, the main clinical manifestations of the patient are obvious low back pain, weakness in lower limbs and limitation of activity. After treatment of local radiotherapy combined with ATRA and arsenic trioxide, the patient achieved and maintained a second complete remission by now.

METHODS: From June 2009 to June 2012, we enrolled into our study 53 cases of thoracolumbar fractures (single segment compressive or burst fractures) without neurologic injury, among whom 28 were treated by mini-open operation via Wiltse approach (group A) and 25 by conventional posterior open surgery (group B). We recorded and compared the intraoperative and postoperative performance between the two groups. RESULTS: There was no serious complications occurring during our study, such as infection, blood vessel injury, spinal cord or nerve root injury. We did not find any statistically difference between the two groups in corrected rate of Cobb's angle or vertebral body height (P>0.05). However, the mini-open method had apparent advantages over the conventional open method in operative time, intraoperative blood loss, postoperative drainage, and postoperative improvement on visual analog scale (VAS) scores at 3 days, 1 month, and 6 months after operation (P<0.05). After 9-24-month follow-up, the number of patients with low back pain in group A was less than that in group B. CONCLUSION: In the premise of strict controlling surgery indications, pedicle screw fixation via Wiltse paraspinal approach has the advantages of simple operation and less trauma in treatment of single-segment thoracolumbar fracture without neurologic injury.

This study aimed to evaluate the diagnostic value of high-frequency ultrasound examination for carpal tunnel syndrome (CTS). A total of 63 wrists from 45 patients diagnosed with CTS were selected as the study group, and 43 asymptomatic wrists of 40 cases were included as the normal control group. Parameters such as the transverse diameter, vertical diameter, cross-sectional area (CSA), and flattening rate (FR) of the carpal tunnel radioulnar joint, postular bone, and median nerve in the hamate bone hook plane were measured, and the differences between the two groups were compared. The median nerve CSA in the postular bone plate was significantly greater in the study group than in the normal control group (0.17±0.05 vs. 0.09±0.02, P<0.01), and the FR at the hook of the hamate was significantly higher in the study group (3.52±0.86 vs. 3.21±0.26, P<0.01). Our results suggest that ultrasonography can effectively provide dynamic real-time images of the wrist in addition to being painless, non-invasive, and associated with relatively low costs. Based on our findings, we believe that ultrasonography is an effective examination method for CTS. When the threshold of the median nerve CSA in the postular bone plate was set as 10 mm(2), the diagnostic sensitivity and specificity were 92% and 86%, respectively. Therefore, the median nerve CSA may represent a good clinical indicator of CTS.

OBJECTIVE: This study aimed to investigate the animal experimental and clinical results of the bone graft fusion of a posterolateral lumbar appendicular bone. METHODS: 1. Sixty rabbits were randomly divided into experimental and control groups. Posterolateral lumbar bone graft with the appendicular bone and iliac bones, respectively, was then performed on these two groups. A lumbar spine X-ray was performed on the postoperative 4(th), 8(th) and 16(th) weeks, and the gray value changes of the bone graft fusion area were measured to calculate fusion rates. Histology analysis was also performed to observe and count osteoblasts. 2. The appendicular bones of 106 patients who suffered from lumbar disorders were cut during lumbar surgery, and a posterolateral lumbar bone graft was performed. The postoperative follow-up used the Steffee criteria to evaluate clinical efficacy and the White criteria to evaluate fusion conditions. RESULTS: No significant difference was observed in the relative gray values of X-ray bone density, bone graft fusion rates, and osteoblast counts in the bone graft regions between the two groups (P > 0.05). The follow-up duration of the 106 patients were 4-8 years (6.12 years), the clinical efficacy rate was 85.85%, and the fusion rate was 83.02%. CONCLUSIONS: The animal experimental and clinical results of posterolateral lumbar bone graft fusion with autologous iliac and appendicular bones were similar.
