OBJECTIVES: The percentage of failure of endodontically treated maxillary molars is relatively high; one main reason is that the second mesiobuccal canal (MB2) is missing. Some techniques have been proposed for detection of the MB2. This study was aimed at assessing the diagnostic accuracy and agreement of the dental microscope and cone-beam computed tomography (CBCT) in comparison with microcomputed tomography (micro-CT) for detection of the MB2 of maxillary first molars in vitro. MATERIALS AND METHODS: This in vitro, experimental study evaluated 71 permanent maxillary first molars that were stored in 100% humidity at room temperature. The teeth were mounted in 9 silicone dental arches to the level of their cementoenamel junction (8 teeth in each arch). The blocks underwent CBCT in a XG3D scanner. Access cavity was then prepared, and the teeth were inspected by a surgical microscope for negotiation of the MB2. Also, micro-CT images were obtained from the teeth to serve as the gold standard. CBCT and micro-CT images were observed by two examiners twice with a 2-week interval. RESULTS: The frequency of the MB2 detected by dental microscope was significantly lower than micro-CT ( < 0.001) and CBCT ( = 0.008); no significant difference existed between micro-CT and CBCT in this respect. The sensitivity, specificity, positive predictive value, and negative predictive value of CBCT for detection of MB2 were 92.6%, 100%, 100%, and 81%, respectively. CONCLUSION: CBCT is superior to the dental microscope for detection of the MB2 of maxillary first molars and can be used for this purpose in the clinical setting with adequate accuracy.

OBJECTIVE: To study the value of pelvic floor ultrasonography in evaluating pelvic floor dysfunction (PFD) after total hysterectomy for cervical cancer. METHODS: All the enrolled patients were given 4D pelvic floor ultrasound examination before and after surgery. The results of ultrasonic examination and the parameters of four-dimensional ultrasonic examination before and after surgery were analyzed, and the quality of life of the patients before and after surgery was evaluated. RESULTS: Postoperatively, the posterior angle of bladder and urethra, the rotation angle of urethra, the decreased value of bladder neck, and the distance between bladder neck and pubic symphysis were (122.60 ± 9.53)°, (136.47 ± 14.67)°, (58.90 ± 18.19)°, (18.14 ± 7.32) mm, and (2.76 ± 0.46) cm, significantly greater than the preoperative (89.90 ± 9.59)°, (107.30 ± 9.96)°, (27.59 ± 10.96)°, (13.27 ± 5.69) mm, and (2.24 ± 0.21) cm ( < 0.05). Postoperative detrusor muscle thickness, bladder neck movement, residual urine volume, and bladder rotation angle (4.48 ± 0.82) mm, (0.64 ± 0.17) cm, (12.82 ± 2.69) ml, (12.11 ± 2.43)° were significantly higher than those of preoperative (3.70 ± 0.64) mm, (0.43 ± 0.18) cm, (4.83 ± 1.07) ml, (4.30 - 1.19)° ( < 0.05). The scores of emotional function, psychological function, social function, and physiological function were (2.35 ± 0.75) points, (2.45 ± 0.66) points, (2.30 ± 0.77) points, and (2.19 ± 0.71) points, significantly higher than those of (1.01 ± 0.50) points, (1.25 ± 0.54) points, and (1.00 ± 0.57) points before surgery, (1.05 ± 0.46) ( < 0.05). CONCLUSIONS: The application of pelvic floor ultrasonography to detect pelvic floor dysfunction after total hysterectomy can clearly display the anatomical structure of the pelvic floor, which is conducive to disease prevention and treatment. Four-dimensional pelvic floor ultrasound can clearly show the postoperative pelvic floor function, which is worthy of clinical promotion and reference.

In order to explore the clinical effect of color Doppler ultrasonography in the diagnosis of subacute thyroiditis, a method for the diagnosis of subacute thyroiditis by color Doppler ultrasonography was proposed. From November 2019 to November 2020, 90 patients with subacute thyroiditis in our hospital were selected as the experimental group; 90 healthy people were selected as the control group during the same period. Both groups were diagnosed by color Doppler ultrasonography and compared. The experimental results showed that patients with subacute thyroiditis showed mild to moderate enlargement of the involved thyroid gland, and local or diffuse inhomogeneous hypoechoic areas may appear in bilateral or unilateral thyroid glands: irregular edges, unclear boundaries, no "ball feel," mottled changes, and accompanied by tenderness. The blood flow signal around the hypoechoic area is rich, and the internal blood flow signal is less. There was no significant increase in the blood flow velocity of the superior thyroid artery on the affected side. Color Doppler ultrasound not only is simple, economical, and non-invasive but also has a good diagnostic accuracy for subacute thyroiditis, which can provide an important basis for clinical diagnosis and treatment and is worthy of popularization and application.

OBJECTIVE: To explore the application value of low-dose CT and MRI in the evaluation of soft tissue injury in tibial plateau fractures. METHODS: This study included 89 patients with high suspicion of TPF and KI admitted to our hospital from July 2015 to May 2021. After arthroscopy, 81 patients were diagnosed with FTP combined with KI. The Schatzker classification based on X-ray and CT plain scan combined with three-dimensional reconstruction was recorded, and the soft tissue injury was recorded according to the MRI examination of the affected knee joint. RESULTS: With the results of pathological examination and arthroscopic surgery as the gold standard, the results of MRI and pathological examination and arthroscopic examination were in good agreement (Kappa = 0.857, 0.844), and CT was moderately in agreement (Kappa = 0.697, 0.694). In KI examination, CT and MRI had no difference in the evaluation of ligament injury and bone injury ( > 0.05), but MRI had better diagnostic effect on meniscus injury ( < 0.05). Finally, the satisfaction survey showed that patients in the CT group were more satisfied with clinical services ( < 0.05). CONCLUSION: Both CT and MRI have certain diagnostic value for occult tibial plateau fractures, among which CT examination is more advantageous for trabecular bone fractures, MRI examination is more advantageous for cortical bone fractures, and MRI examination can improve occult tibial plateau fracture inspection accuracy.

In order to solve the problem of the difference in the diagnostic effect of different sequences of magnetic resonance imaging (MRI) examinations for anterior and posterior cruciate ligament injuries, the author proposes an MRI rehabilitation method to relieve anterior cruciate ligament injury in dancers. This method retrospectively analyzed the clinical data of 60 patients with knee anterior and posterior cruciate ligament injuries in our hospital, and all patients were diagnosed with knee anterior and posterior cruciate ligament injuries. All patients underwent MRI 3D sequence and 2D sequence examination successively to compare anatomical measurements. This study aimed at comparing the measurements of the posterior cruciate ligament (PCL) and anterior cruciate ligament (ACL) between the two examination sequences; comparing the diagnosis; comparing the grading and judgment of the anterior and posterior cruciate ligament injuries of the knee joint between the two inspection sequences; and comparing the diagnostic coincidence rates of the two examination sequences in the complete tear of the anterior and posterior cruciate ligaments of the knee. Experimental results show that, in terms of PCL and ACL, the angle, thickness, and length of two-dimensional MRI examination were significantly different from those of MRI examination and anatomical measurement ( < 0.05); for PCL and ACL, the angle, thickness, and length of 3D MRI were not significantly different from anatomical measurements ( > 0.05). The diagnostic accuracy of 2D MRI was 83.33%, which was lower than 95.00% of 3D MRI ( < 0.05). There was no significant difference in the grading of anterior and posterior cruciate ligament injuries between the two examination sequences ( > 0.05). The diagnostic coincidence rates of 3D MRI and 2D MRI for complete tear of the anterior and posterior cruciate ligaments were 95.55% and 80.00%, respectively ( < 0.05). In conclusion, three-dimensional MRI examination can obtain higher diagnostic value for patients with knee joint anterior and posterior cruciate ligament injury.

In order to solve the problems of inaccurate information collection, incomplete information collection, and inconsistency of collected images in traditional sports injury collection methods, an application method of moving target information perception technology in intelligent supervision system is proposed. By judging and analyzing the potential motion damage posture of the motion posture intelligent tracking images, the collected motion intelligence tracking images are judged. The intelligent tracking image matrix can make up for the shortcomings of traditional images that are not connected, complete the identification, detect potential damage in time, and take targeted preventive measures and means. Finally, according to the target detection algorithm and target tracking algorithm, combined with OpenCV computer vision library and QT image library, an intelligent video surveillance target tracking simulation system is developed. The algorithm studied in this paper is to realize the target tracking function of the intelligent video surveillance system. Through the comparison of experimental results, the design method can accurately collect damage attitude information, without calculating continuous values, and the use of three-dimensional images in the positioning process can analyze the damage attitude from multiple angles.

OBJECTIVE: To investigate the diagnostic value of endoscopic narrow-band imaging technique in early gastric cancer and precancerous lesions. METHODS: A total of 100 patients with recurrent upper gastrointestinal symptoms in our hospital from January 2017 to January 2022 were selected and divided into group A and group B according to the random number table method, with 50 cases in each group. Group A received white light endoscopy, and group B received narrow-band imaging technology combined with endoscopy. Narrow-band imaging combined with magnifying endoscopy was used to stain the area with suspicious mucosal lesions with indigo carmine and magnified observation. RESULTS: The endoscopic image clarity of group B was significantly better than that of group A in terms of lesion outline, gastric pit, and microvascular morphology ( < 0.05). There were 10 cases of early gastric cancer, 18 cases of benign lesions, and 9 cases of gastric cancer (nonearly stage); 17 cases of precancerous lesions, 12 cases of early gastric cancer, 13 cases of benign lesions, and 6 cases of gastric cancer (nonearly stage) were diagnosed by ordinary white light endoscopy. Pathological results confirmed that among the 50 patients in group B, there were 15 cases of precancerous lesions, 11 cases of early gastric cancer, 17 cases of benign lesions, and 7 cases of gastric cancer (nonearly stage). Among the 50 patients in group A, 16 were precancerous lesions, 11 were early gastric cancer, 15 were benign lesions, and 8 were gastric cancer (non early stage). In the diagnosis of precancerous lesions and early gastric cancer, the diagnostic consistency, sensitivity, and specificity of group B were better than those of group A ( < 0.05); NBI combined with endoscopy in the diagnosis of precancerous lesions and early gastric cancer (kappa = 0.860, kappa = 0.883) was more consistent with pathological diagnosis than common white light endoscopy (kappa = 0.433, kappa = 0.535). CONCLUSION: The value of narrow-band imaging technology combined with endoscopy in the diagnosis of precancerous lesions and early gastric cancer is better than that of ordinary white light endoscopy, and it can be widely used in clinical practice.

OBJECTIVE: To investigate the meniscus characteristics of knee osteoarthritis and its guiding significance for minimally invasive surgery. METHODS: A total of 100 patients with knee meniscus sports injuries who were treated in our hospital from January 2019 to January 2022 were selected as the research subjects and were grouped according to the interval between injury and surgery, with an interval of 2 months: the early group (53 cases) within 2 months and the delayed group (47 cases) with an interval of more than 2 months. The distribution of intraoperative complications in the two groups was observed and recorded, and the changes in pain degree, joint range of motion, knee joint function, and quality of life scores before and after operation were compared between the two groups. RESULTS: The postoperative VAS score, range of motion, Lysholm score, IKDC knee subjective function score, and quality of life score were significantly improved in both groups ( < 0.05). The incidence of intra-articular cartilage injury in the delayed group was significantly higher than that in the early group ( < 0.05). The patellofemoral cartilage injury was the main part of intra-articular cartilage injury in the two groups, and the incidence of patellofemoral cartilage injury in the delayed group was significantly higher than that in the early group ( < 0.05). The cartilage damage was mainly cartilage damage, and the grades I-II and III-IV cartilage damages were significantly increased in the extension group. CONCLUSION: Meniscal injury in knee osteoarthritis has certain microscopic characteristics. In this paper, the microscopic classification of meniscus injury in knee osteoarthritis is helpful to guide microscopic surgery and improve the minimally invasive knee osteoarthritis effect of surgical treatment.

In order to explore the changes and clinical significance of serum TNF- and IL-6 and ET levels in the pathogenesis of hypertensive disorders of pregnancy (HDIP), echocardiography, and serum IL-6 and TNF- changes in pregnant women with a hypertensive disorder, a clinical analysis method was proposed. A retrospective analysis of 59 pregnant women who visited the obstetrics department of a provincial hospital was divided into 2 groups. The normal control group consisted of 32 normal, uncomplicated pregnant women; the preeclampsia group included 27 patients with systolic blood pressure > 140 mmHg and/or diastolic blood pressure > 90 mmHg who developed proteinuria after 20 weeks of gestation. The levels of TNF- and IL-6 in serum of normal pregnant women and pregnant women with preeclampsia were detected by enzyme-linked immunosorbent assay (ELISA). The results showed that compared with normal pregnant women, the serum levels of TNF- and IL-6 in the early pregnant women of Zizhi were significantly increased, and the trend of increased TNF- and IL-6 levels was related to the severity of complications. With the mean pulmonary arterypressure > 50 mmHg, the serum TNF- level of pregnant women was significantly higher than that of pregnant women with mean pulmonary arterypressure < 50 mmHg. The analysis found that the serum levels of TNF- and IL-6 in patients with hypoxic gestational hypertension were significantly increased, and the results of lung tissue immunohistochemistry also showed that serum TNF- and IL-6 levels in patients with hypoxic gestational hypertension were significantly increased. And serum TNF- and IL-6 levels were positively correlated with right ventricular systolic blood pressure (RVSP). . This study revealed that the elevated levels of serum TNF- and IL-6 are closely related to the pathophysiological process of gestational hypertension. Serum levels of TNF- and IL-6 and ET were significantly increased, and the changes of serum TNF- and IL-6 and ET levels had important clinical value for closely monitoring the severity of the disease and the development of the disease.

In order to explore the situation of ankle sports injury in physical education, the author proposed the application method of MRI in sports injury prevention in physical education. In a retrospective analysis of 28 patients with clinically diagnosed ankle injuries, taking ankle arthroscopy/incision as the standard, the sensitivity and diagnostic value of MRI examination for ankle sports injury were analyzed statistically. The result shows that 6 cases of ankle fracture were correctly diagnosed by MRI, and the diagnostic sensitivity for bone marrow contusion and edema was 100%. Among the 19 cases of clinically diagnosed ankle ligament injury, 16 cases were diagnosed by MRI, and the overall sensitivity was 84%. Of the 8 cases of calcaneofibular ligament injury, 6 cases were correctly diagnosed by MRI, with a sensitivity of 75%. . 3.0 T MRI examination has high sensitivity for ligament, tendon, and cartilage injury, which can well show ankle joint injury and provide an objective basis for early clinical treatment and rehabilitation.

OBJECTIVE: To determine the proportion of intravoxel incoherent motion diffusion-weighted images (IVIM-DWI) and three-dimensional arterial circulation markers (3D-ASL) in Ki-67 labeling index (Ki-67 LI) and glioma grading. METHODS: According to the classification of diseases of the central nervous system dealt with by WHO in 2007, patients with stage II glioma were classified as low ( = 20) and patients with stages III-IV were divided into higher levels ( = 22). Prior to surgery, brain MRI, IVIM-DWI, and 3D-ASL were performed in all patients, and the actual water molecular diffusion coefficient (), microcirculation coefficient (∗), blood flow fraction (), and cerebral blood flow (CBF) were measured. A rank sum (Mann-Whitney test) was used to compare the four upper and lower level Ki-67 LI measurements. Spearman's method is used to identify the relationship between 4 groups of quantification and Ki-67 LI. Reciprocal grafting (ROC) curves were used to measure the diagnosis of four groups of glioma grading defects. RESULTS: There were significant differences in , ∗, , and CBF between the solid region of the tumor and the normal white matter contralateral to it ( < 0.05). The significant differences of , ∗, , and CBF were shown between patients with low-grade glioma and high-grade glioma ( < 0.05). Ki-67 LI was found to have negative correlation with ( = 00.693, < 0.001) and ( = 00.539, < 0.001), but similarly correlated with CBF ( = 0.665, < 0.001) in patients with glioma. Recipient efficacy for predicting advanced and secondary glioma from , , ∗, CBF, and Ki-67 LI raises AUCs of 0.819, 0.747, 0.719, 0.836, and 0.907, respectively. CONCLUSION: IVIM-DWI has good application value for preoperative grading of glioma.
