ObjectiveTo investigate the effect of high-definition transcranial direct current stimulation (HD-tDCS) combined with upper limb robot on upper limb dysfunction in patients with ischemic stroke. MethodsFrom January, 2023 to March, 2024, 56 inpatients with upper limb dysfunction after ischemic stroke were selected from Zhejiang Rehabilitation Medical Center, and divided into control group (n = 28) and experimental group (n = 28) randomly. All the patients received comprehensive treatment and upper limb robot training, while the control group received sham HD-tDCS and the experimental group received HD-tDCS, for four weeks. They were assessed with Fugl-Meyer Assessment-Upper Extremities (FMA-UE), Wolf Motor Function Test (WMFT) and modified Barthel Index (MBI) before and after treatment. The cortical amplitude, cortical latency and central motor conduction time (CMCT) of transcranial magnetic stimulation motor-evoked potential (MEP) were recorded, and a correlation analysis was conducted. ResultsThe scores of FMA-UE, WMFT and MBI, and MEP cortical amplitude, cortical latency and CMCT improved in both groups after treatment (t > 3.177, P < 0.01), and they were better in the experimental group than in the control group (t > 3.610, P < 0.01). The scores of FMA-UE and WMFT negatively correlated with MEP cortical latency and CMCT, and positively correlated with MEP cortical amplitude (|r| > 0.448, P < 0.001). ConclusionHD-tDCS is effective on upper limb motor function and activities of daily living for patients with ischemic stroke, and can improve corticospinal motor conduction.

Objective:To explore the effects of a tiered-categorized-integrated training model in standardized neurology residency training.Methods:This controlled before-and-after study enrolled 109 residents who rotated in the Department of Neurology of Renji Hospital of Shanghai Jiao Tong University School of Medicine from January 2023 to June 2024. Among them, 43 residents from January to July 2023 were assigned to control group to receive the traditional training model, while 66 residents from August 2023 to June 2024 were assigned to observation group to follow the competency-oriented tiered-categorized-integrated training protocol. In the observation group, the residents were categorized into neurology specialty and non-neurology specialty groups to follow a competency-based hierarchical and progressive training approach with systematical optimization and resource integration in terms of faculty allocation, training activities, and assessment evaluations. The effectiveness of the models was evaluated through semi-annual assessments (for neurology specialty), routine assessments and end-of-rotation assessments (for non-neurology specialty), and 360-degree evaluations. SPSS 26.0 was used to perform chi-square tests and t-tests. Results:The non-neurology specialty residents in the observation group significantly outperformed the control group in the total score of end-of-rotation assessments [(90.93±4.21) vs. (86.08±8.98), P=0.004], theoretical examinations [(16.47±2.47) vs. (13.55±5.34), P=0.003], clinical skills [(9.32±0.47) vs. (9.00±0.58), P=0.004], and case analysis [(86.75±5.95) vs. (82.64±11.20), P=0.047]. The neurology specialty residents in the observation group showed a significantly higher physical examination score than the control group [(87.50±8.66) vs. (75.00±8.17), P=0.040]. Furthermore, in the 360-degree evaluation, the observation group exhibited better performance in certain assessment indicators of core competencies, including professional ability, patient management, professionalism, and communication and cooperation ( P<0.05). Conclusions:The tiered-categorized-integrated training model helps residents to better grasp basic knowledge and skills in rotations, and also enhances their core competencies such as professional ability, patient management, and communication and cooperation. This model provides a replicable practical solution for clinical departments to achieve efficient and precise rotation management within the constraints of limited resources.

Objective:To assess the core competencies of internal medicine residents undergoing standardized residency training and to explore the effectiveness of core competency evaluation on mobile devices.Methods:The mobile formative evaluation module was developed based on the "Xueyiku" teaching management platform. From January to December 2023, clinical teachers were asked to evaluate 150 internal medicine residents based on the "Resident Core Competency Milestone Evaluation System in China Consortium of Elite Teaching Hospitals", and the results were analyzed using non-parametric tests.Results:Among the six core competencies of internal medicine residents, professionalism received the highest score, whereas teaching skill received a lower score (97.50 vs. 90.00; H=167.31, P<0.001). Second-year residents had significantly higher scores than first-year residents (93.00 vs. 90.00; P<0.001), but similar scores to third-year residents (93.00 vs. 93.00; P>0.05). In addition, there was no significant difference in score among residents with different medical education backgrounds ( P>0.05). Conclusions:More emphasis should be placed on improving the teaching skills of internal medicine residents, along with the implementation of tiered progressive training. The mobile core competency evaluation is an effective means for assessing the comprehensive skills of residents in a timely manner.

Objective:To investigate the clinical application effect of Zishen Yutai Pill in patients with repeated implantation failure (RIF) undergoing frozen-thawed embryo transfer (FET) cycles.Methods:A retrospective case-control study was conducted, selecting 744 cycles of patients with RIF at the Department of Female Reproductive Medicine,State Key Laboratory of Reproductive Medicine and Offspring Health, Center for Reproductive Medicine, Institute of Women, Children and Reproductive Health, Shandong University from October 2017 to April 2023. The patients were divided into experimental group (treated with Zishen Yutai Pill, n=279) and control group (treated without Zishen Yutai Pill, n=465) based on whether Zishen Yutai Pill was added to luteal support. The pregnancy outcomes between the two groups were compared. Based on the different endometrial preparation protocols in the FET cycles, the patients were used down-regulation protocol ( n=271) or non-down-regulation protocol ( n=473). The pregnancy outcomes of the two groups in each protocol were compared. Results:There were no statistically significant differences between the two groups in terms of biochemical pregnancy rate, clinical pregnancy rate, embryo implantation rate, early miscarriage rate, late miscarriage rate, and live birth rate (all P>0.05). However, the biochemical pregnancy rate [69.0% (58/84)], clinical pregnancy rate [59.5% (50/84)], and embryo implantation rate [59.4% (57/96)] in the experimental group of the down-regulated protocol were significantly higher than those in control group [56.1% (105/187), P=0.045; 46.5% (87/187), P=0.048; 44.9% (92/205), P=0.019], with statistically significant differences. In the non-down-regulated protocol, there were no statistically significant differences in pregnancy outcomes between the two groups (all P>0.05). Conclusion:In the FET down-regulated protocol, Zishen Yutai Pill can significantly improve the clinical pregnancy rate and the embryo implantation rate in patients with RIF, thereby improving pregnancy outcomes.

Objective:To develop the Self-management Behavior Questionnaire for Middle-aged and Young Patients with Myocardial Infarction and test its reliability and validity.Methods:Using social cognitive theory, self-efficacy theory, and self-management theory as theoretical frameworks, a preliminary questionnaire was formed through literature review, semi-structured interviews, and Delphi expert consultation. Convenience sampling was used to select middle-aged and young patients with myocardial infarction from the First Affiliated Hospital of Henan University of Chinese Medicine, Henan Provincial Chest Hospital, and the Second Affiliated Hospital of Zhengzhou University from June to July 2022 for investigation, and item analysis and exploratory factor analysis of the questionnaire were conducted. From August to November 2022, middle-aged and young patients with myocardial infarction from the Heart Center of the First Affiliated Hospital of Henan University of Chinese Medicine were selected for investigation, and confirmatory factor analysis and reliability testing of the questionnaire were conducted.Results:A total of 300 and 480 questionnaires were distributed, respectively, and 280 and 468 valid questionnaires were collected, with effective response rates of 93.33% (280/300) and 97.50% (468/480), respectively. The Self-management Behavior Questionnaire for Middle-aged and Young Patients with Myocardial Infarction included 31 items. The total Cronbach 's α coefficient of the questionnaire was 0.918, the half reliability coefficient was 0.853, and the retest reliability coefficient was 0.975. The content validity index of the questionnaire level was 0.965, and the content validity index of the item level was 0.830 to 1.000. Exploratory factor analysis extracted 6 common factors with a cumulative variance contribution rate of 69.795%. Confirmatory factor analysis showed that the model fitted well and the questionnaire factor structure was stable. Conclusions:The Self-management Behavior Questionnaire for Middle-aged and Young Patients with Myocardial Infarction developed in this study has good reliability and validity, which can provide references for medical and nursing staff to evaluate the self-management behavior of middle-aged and young patients with myocardial infarction.

Objective To compare the effect of postoperative between total intravenous anesthesia(TIVA)use of alfentanil and remifentanil undergoing endoscopic sinus surgery.Methods A total of 130 and thirty patients scheduled for endoscopic sinus surgery,62 males and 68 females,aged 18-64 years,BMI 18-30 kg/m2,ASA physical status Ⅰ or Ⅱ,were randomly divided into two groups:alfentanil group(group A)and remifentanil group(group R).Midazolam 0.02 mg/kg,propofol target-controlled infusion(TCI)3 μg/ml,alfentanil 20 μg/kg,and rocuronium 0.6 mg/kg were injected intravenously in group A,and target-controlled infusion of propofol combined with alfentanil was used to maintain anesthesia.Midazo-lam 0.02 mg/kg,propofol TCI 3 μg/ml,remifentanil 1 μg/kg,and rocuronium 0.6 mg/kg were injected intravenously in group R,and target-controlled infusion of propofol combined with remifentanil was used to maintain anesthesia.The number of intraoperative hemodynamic adverse reactions such as hypertension,tachycardia,hypotension,bradycardia during operation,and pain degree at 30 minutes,60 minutes,24 hours after operation,extubation time,and rescue analgesia and adverse reactions such as nausea and vomi-ting,skin pruritus,respiratory depression within 24 hours after operation were recorded.Results Compared with group R,the incidence of intraoperative hypotension in group A was significantly lower(P＜0.05),the incidence of painless in group A 30 and 60 minutes after operation was significantly higher(P＜0.05),the incidence of mild and moderate pain was significantly decreased(P＜0.05),and the recovery time was significantly prolonged(P＜0.05).There was no significant difference in rescue analgesia within 24 hours after operation.There were no significant differences in the incidence of postoperative nausea and vomiting,postoperative skin pruritus,and respiratory depression between the two groups.Conclusion In endoscopic sinus surgery,the effect of total intravenous anesthesia with alfentanil on postoperative analgesia is better than that of remifentanil,and the incidence of perioperative and postoperative adverse reactions in alfentanil is lower than that of remifentanil,while the recovery time of alfentanil is slightly longer than that of remifentanil.

Objective To investigate the possible influence of long-term antiviral therapy with entecavir on renal function in patients with chronic hepatitis B (CHB) and the sensitive indicators for early identification of renal injury. Methods A cross-sectional real-world study was conducted for the clinical data of 125 CHB patients treated with entecavir for more than 1 year (treatment group) and 44 patients with chronic HBV infection who did not receive antiviral therapy (control group), including the changes in serum creatinine (SCr), estimated glomerular filtration rate (eGFR), and the levels of urinary α1 microglobulin (α1-MG), β2 microglobulin (β2-MG), and N-acetyl-β-D-glucosaminidase (NAG). The chi-square test or the Fisher's exact test was used for comparison of categorical data between groups. The independent-samples t test was used for comparison of normally distributed continuous data between groups, and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between groups. The Logistic regression analysis was used to investigate independent influencing factors for abnormal urinary α1-MG, β2-MG, and NAG in the treatment group. Results There were no significant differences in SCr and eGFR between the treatment group and the control group ( t =0.999 and -1.259, P > 0.05), and both indices were within the normal range in these two groups. The treatment group had significantly higher abnormal rates of urinary α1-MG and β2-MG than the control group (47.2%/42.4% vs 13.6%/13.6%, χ 2 =15.693 and 12.567, both P < 0.001), and compared with the control group, the treatment group had a significantly higher proportion of patients with α1-MG or β2-MG > 2×upper limit of normal (18.4%/21.6% vs 2.3%/4.5%, both P < 0.05); however, there were no significant differences between the treatment group and the control group in the abnormal rate of urinary NAG (8.0% vs 6.8%, P > 0.05) and the proportion of patients with urinary NAG > 2×upper limit of normal (8.8% vs 6.8%, P > 0.05). Compared with the control group, the treatment group had a significantly higher proportion of patients with abnormalities in two or more indicators for renal tubular injury (33.6% vs 11.4%, χ 2 =8.519, P < 0.05), while there was no significant difference between the two groups in the proportion of patients with abnormalities in one indicator (16.0% vs 11.4%, P > 0.05). Conclusion Long-term treatment of CHB with entecavir may be associated with the risk of renal tubular dysfunction, and abnormalities in more than two indicators for renal injury may help to identify renal tubular dysfunction in patients, so as to adjust related treatment in time.
