Preliminary construction of evaluation index system of lumbar puncture teaching for medical students based on Delphi method and analytic hierarchy process / 中华医学教育探索杂志

Objective:To construct the evaluation index system of lumbar puncture teaching for medical students, aiming to create a scientific assessment and evaluation method covering theoretical knowledge, skill practice, and professional accomplishment, so as to comprehensively evaluate the teaching effect of lumbar puncture for medical students, and improve the practical ability of clinical skills of medical students more effectively.Methods:The evaluation index scheme of lumbar puncture teaching for medical students was initially formulated through literature review and group discussion, and 20 experts related to clinical front-line work and medicine were invited to revise the scheme by applying Delphi expert consultation and applying analytic hierarchy process to quantify the entries and establish the final index weights at all levels.Results:The valid recovery rate of both rounds of expert consultation questionnaires in this study was 100%. The second round of expert consultation was conducted without changing experts, with an authority factor of 0.88. Kendall's coefficient of harmony was 0.136 and 0.184, respectively. After two rounds of expert consultation, the evaluation index system of lumbar puncture teaching for medical students, including 3 primary indicators (theoretical knowledge, comprehensive clinical ability and professionalism), 7 secondary indicators and 22 tertiary indicators, was initially constructed.Conclusion:The evaluation index system of lumbar puncture teaching for medical students constructed in this study is scientific and credible, which can provide quantitative basis for the training and assessment of medical students, and is of great theoretical and practical significance.

Design and Implementation of the Scientific Data Management Platform of Traditional Chinese Medicine / 医学信息学杂志

Purpose/Significance To address the challenge of low willingness to share scientific data among stakeholders in the tradi-tional Chinese medicine(TCM)industry,and to promote standardization,aggregation,sharing,and application of scientific data in the field of TCM.Method/Process By adhering to national standards for scientific data submission and management,integrating technologies such as blockchain and digital watermarking,the study aims to establish atrusted process for the exchange of scientific data in the field of TCM and build a TCM scientific data management platform.Result/Conclusion This platform will provide information technology support for regional TCM scientific data exchange,and effectively improve the efficiency and willingness of scientific data exchange within the region.

Effects of fenofibrate on hepatocyte apoptosis in nonalcoholic fatty liver / 中华肝脏病杂志

<p><b>OBJECTIVE</b>To use a rat model of nonalcoholic liver disease (NAFLD) to observe effects of the peroxisome proliferator-activated receptor-a (PPAR-a) agonist fenofibrate on hepatic steatosis in nonalcoholic fatty liver and to investigate the underlying mechanism.</p><p><b>METHODS</b>Sixty-six Sprague-Dawley rats were given adaptive feeding for 1 week and then randomly allocated into the following three groups: unmodeled control (group C,n =18), untreated NAFLD model (group M, n =24), and fenofibrate-treated NAFLD model (group F, n =24).Group C rats were given a normal diet, while group M and group F rats were given a high-fat diet. After model establishment, the group F rats were treated with fenofibrate (10 mg/kg/d, intraperitoneal) and the group C and group M rats were given sham-treatment with cosolvent (5 mL/kg/d, intraperitoneal). At the end of treatment weeks 4, 6 and 8, one-third of rats in each group were euthanized.Liver tissues were assessed by hematoxylin-eosin (HE) staining to determine level of steatosis and inflammaion activity, and by terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling to measure changes in hepatocyte apoptosis index. Changes in expression levels of the PPAR-a receptor and apoptosis factors (bcl-2, bax and caspase-3) were assessed by reverse transcription-PCR and immunohistochemistry.</p><p><b>RESULTS</b>The NAFLD modeled rats showed appropriate induction of hepatic steatosis, hepatic inflammation, and hepatocyte apoptosis. Compared to the group M rats, the group F rats showed lower expression of PPAR-and bcl-2 and higher expression of bax and caspase-3 at both the mRNA and protein level.</p><p><b>CONCLUSION</b>Fenofibrate can ameliorate hepatic steatosis in an experimental rat model of NAFLD, and the mechanism may be associated with inhibition of hepatocyte apoptosis.</p>

Action of Tuina on Retro-positioning of Skull Spatial Offset in Patients with Cervical Vertigo / 针灸推拿医学（英文版）

Objective:To investigate the onset mechanism of cervical vertigo from the proprioceptive sensation and provide clinical basis for its treatment.Methods:Among the 121 cases that conformed to the diagnostic criteria of cervical vertigo,70 cases who presented with negative neck-rotation test and cervical vertigo without obvious vascular factors by transcranial Doppler(TCD)were assigned to the observation group,while 51 cases who presented with positive neck-rotation test and cervical vertigo due to spasm of vertebral basal artery or insufficient blood supply by TCD were assigned to the control group.The cases in the two groups were treated once every day,5 days make up one treatment course and the resuIts were statistically analyrzed after one treatment course.Results:The skull triaxial spatial offset of the cases in the two groups were significantly reduced after the treatment (P<＜0.01).However, there was no statistically significant difference between the skull triaxial spatial offset between the two groups (p＞0.05).It is not conclusive that the therapeutic effect in the two groups was significantly different after one treatment course.Conclusion:Tuina manipulation therapy can improve the skull spatial ofrset repositioning ability of the Patients.

Influence of Manual Manipulations on Reversal Ability of Skull Space in Patients with Vertigo / 针灸推拿医学（英文版）

Purpose: To study the influence of the manual manipulations on the reversal ability of the skull space in the patients with vertigo due to proprioceptive disturbance of the neck. Methods: By motor surveyor of skull three-dimensional space, the changes in the reversal ability of the skull space before and after the treatments with manual manipulations were observed in 72 cases of the patients with vertigo due to proprioceptive disturbance of the neck. Besides, 51 cases of vertigo due to insufficient blood supply of the cervical artery and 138 normal adults were selected as the control group. Results:After the treatments with manual manipulations, the deviation degree of the skull space in the three motor axes were all obviously decreased in the proprioceptive group, more obviously in the flexing and extending direction. The deviation degree of the skull space was also decreased in the ischemic group in the flexing and extending direction. Conclusion: Manual manipulations have the instant function to improve the proprioceptive function of the neck, and the factor of the proprioceptive disturbance also exists in the clinical onset of vertigo in pattern of insufficient blood supply of the cervical artery.
