BACKGROUND:The landing error scoring system test is a standard for assessing the risk of non-contact injuries and has not yet been developed for Chinese college soccer programs. OBJECTIVE:To establish a test evaluation standard for the landing error scoring system to provide a basis for evaluating the risk of non-contact injuries in college soccer students. METHODS:A prospective cohort study was designed in which 219 athletes from 10 college soccer teams were tested with the standard landing error scoring system,and the subjects were followed up by questionnaires and medical examinations for non-contact injuries of the lower extremities and trunk for 1 year after testing to determine sex differences and assessment criteria for the landing error scoring system test indicators. RESULTS AND CONCLUSION:The total score of the landing error scoring system was(8.22±1.65)points for 219 subjects,(8.29±1.74)for males and(8.07±1.44)for females,with no significant difference between males and females(P>0.05).Within 1 year after the test,the overall injury rate of 219 subjects was 10.05%and the morbidity rate was 15.98%;the injury rate of male subjects with non-contact injury of the lower limbs and trunk was 12.75%and the morbidity rate was 20.13%;the injury rate of female subjects with non-contact injury of the lower limbs and trunk was 4.29%and the morbidity rate was 7.14%.There were no significant differences in the injury rate between men and women(P<0.05).The total score of the landing error scoring system was higher in the injury group than in the non-injury group[(9.50±1.14)vs.(8.08±1.64),P<0.01];for male subjects,the total score of the landing error scoring system was higher in the injury group than in the non-injury group[(9.63±1.12)vs.(8.09±1.73),P<0.01].The area under the curve for the total score of the landing error scoring system was 0.773(P=0.000),which had a diagnostic value for the risk of non-contact injury of the lower extremities and trunk in male subjects,with a best cut-off point of 8.5,sensitivity of 0.842,specificity of 0.623,positive likelihood ratio of 2.233,negative likelihood ratio of 0.254,relative risk factor of 8.400,and odds ratio of 8.816;the total score of the landing error scoring system was not applicable for assessing the risk of non-contact injury of the lower extremities and trunk in female subjects.To conclude,the landing error scoring system test can be used as a criterion to assess the risk of non-contact injury to the lower extremity and trunk in Chinese college male soccer players,with an optimal cut-off point of 8.5.The risk of non-contact injury to the lower extremity and trunk is 8.40 times higher in male athletes with a landing error scoring system test score of≥8.5 than in male athletes with a score of<8.5.

Temporomandibular joint (TMJ) diseases are common clinical conditions. The number of patients with TMJ diseases is large, and the etiology, epidemiology, disease spectrum, and treatment of the disease remain controversial and unknown. To understand and master the current situation of the occurrence, development and prevention of TMJ diseases, as well as to identify the patterns in etiology, incidence, drug sensitivity, and prognosis is crucial for alleviating patients′suffering.This will facilitate in-depth medical research, effective disease prevention measures, and the formulation of corresponding health policies. Cohort construction and research has an irreplaceable role in precise disease prevention and significant improvement in diagnosis and treatment levels. Large-scale cohort studies are needed to explore the relationship between potential risk factors and outcomes of TMJ diseases, and to observe disease prognoses through long-term follw-ups. The consensus aims to establish a standard conceptual frame work for a cohort study on patients with TMJ disease while providing ideas for cohort data standards to this condition. TMJ disease cohort data consists of both common data standards applicable to all specific disease cohorts as well as disease-specific data standards. Common data were available for each specific disease cohort. By integrating different cohort research resources, standard problems or study variables can be unified. Long-term follow-up can be performed using consistent definitions and criteria across different projects for better core data collection. It is hoped that this consensus will be facilitate the development cohort studies of TMJ diseases.

Objective:To explore the predictive value of the change rate of parathyroid hormone (PTH) after total thyroidectomy (TT) for hypoparathyroid function.Methods:A total of 182 patients with thyroid tumor who underwent TT from Jan. 2018 to Jun. 2023 in the Department of Otolaryngology, Head and Neck Surgery, Second Hospital of Shanxi Medical University were retrospectively selected as the study objects. The clinical and surgical data of the patients were collected, and the key factors associated with postoperative hypoparathyroidism were screened by multi-factor analysis. The change rate of serum PTH was calculated during perioperative period (before operation, at the end of operation, 1 and 3 days after operation). Receiver operator curve (ROC) was used to analyze the predictive value of PTH change rate in all patients.Results:Whether temporary hypoparathyroidism (THP) or permanent hypoparathyroidism (PHP), both were closely related to TT+ bilateral central lymph node dissection ( χ2=33.764, 9.235, P < 0.05) and parathyroid resection ( χ2=6.512, 58.999, P < 0.05). The change rate of PTH in HP patients was significantly higher than that in normal patients ( F=15.993, 16.830, 19.024, P < 0.05), and on the first and third day after surgery, the change rate of PTH in PHP patients was significantly higher than that in THP patients ( t=7.955, 9.023, P < 0.05). The predicted area under curve (AUC) of THP or PHP in different patient populations is different with the change rate of PTH in different periods. For patients with TT+ bilateral central lymph node dissection and parathyroidectomy, the change rate of PTH at the end of surgery was significantly higher than the change rate of PTH at 3 days after surgery for the AUC with PHP ( Z=5.433, 4.923, P < 0.05) . Conclusion:Perioperative PTH has good predictive value for THP and PHP in TT patients, especially in TT+ bilateral central lymph node dissection and parathyroidectomy.

Objective:To analyze the factors influencing the poor effect of short-term electrical spinal cord stimulation in the treatment of postherpetic neuralgia (PHN).Methods:The medical records of PHN patients of either sex, aged 40-85 yr, of American Society of Anesthesiologists Physical Status classification Ⅰ or Ⅱ, who received short-term electrical spinal cord stimulation from July 2017 to July 2022, were retrospectively collected. The therapeutic effect was evaluated using the modified MacNab criteria at 3 months after operation, and the patients were divided into good efficacy group (excellent and good efficacy) and poor efficacy group (fair and poor efficacy). General information, disease course, lesion site, complicated diseases, ossification of the yellow ligament in the diseased spinal segment, severity of pain in the herpetic stage, standard antiviral therapy in the herpetic stage (for more than 7 days) and use of neurotrophic drugs in the herpetic stage (for more than 7 days) were collected. Multivariate logistic regression analysis was used to screen the influencing factors for the poor effect of electrical spinal cord stimulation in the treatment of PHN.Results:A total of 168 patients were eventually enrolled, among which 69 had poor curative effect, and the rate of poor curative effect was 41.1%. The results of multivariate logistic regression analysis showed that the patient′s age ( OR=2.230, P=0.015), course of disease ( OR=2.191, P=0.027), complication with diabetes mellitus( OR=8.859, P=0.010), ossification of ligamentum flavum at the same segment ( OR=6.602, P=0.019), severity of pain in the herpetic stage ( OR=5.788, P=0.038) and non-standard antiviral therapy in the herpetic stage ( OR=6.765, P=0.021) were the influencing factors for the poor effect of electrical spinal cord stimulation in the treatment of PHN. Conclusions:Age, course of disease, complication with diabetes mellitus, ossification of ligamentum flandum at the same segment, severity of pain in the herpetic stage and non-standard antiviral therapy in the herpetic stage are the factors influencing the poor effect of short-term electrical spinal cord stimulation in the treatment of PHN.

Objective:To evaluate the curative effect of percutaneous transhepatic choledoscopy (PTCS) in the treatment of complex intrahepatic and extrahepatic bile duct stones.Methods:Clinical data of 120 patients with complex intrahepatic and extrahepatic bile duct stones admitted to Baiyin Second People's Hospital from January 2021 to December 2021 were retrospectively analyzed, including 74 males and 46 females, aged (53.3±2.4) years old. Patients were divided the control group ( n=60) who underwent routine laparotomy and the observation group ( n=60) who underwent PTCS. Perioperative outcomes, including the intraoperative blood loss, operation time, postoperative exhaust time, stress status, liver function index [serum level of alanine aminotransferase (ALT) and aspartate aminotransferase (AST)] and postoperative complications of the two groups were compared. Results:Compared with the control group, the observation group had a shorter operation time [(1.62±0.24) h vs. (2.35±0.28) h] and postoperative exhaust time [(1.80±0.25) d vs. (2.53±0.28) d], and a decreased intraoperative blood loss [(51.21±8.23) ml vs. (119.21±8.29) ml] (all P<0.05). The serum levels of adrenaline [(119.7±12.0) ng/ml vs. (130.5±14.2) ng/ml], ALT [(70.02±2.42) U/L vs. (87.30±2.56) U/L] and AST [(188.6±24.7) U/L vs. (201.7±28.5) U/L] were lower in observation group one day after surgery (all P<0.05). The total effective rate in observation group was higher than that in control group [96.7%(58/60) vs. 83.3%(50/60), P=0.005]. The rate of complications was also lower in observation group [6.7%(4/60) vs. 36.7%(22/60), P=0.005]. Conclusion:Compared to routine laparotomy, PTCS could be more feasible for complex intra- and extrahepatic bile duct stones, considering its minimal invasiveness, less stress reaction, enhanced postoperative recovery, less disturbance of liver function, and decreased complications.
