BACKGROUND:Deep muscle stimulation has the effects of releasing muscle adhesion,relieving muscle spasm,improving and restoring muscle compliance and elasticity.Electromyographic biofeedback therapy can promote nerve recovery and improve lower limb motor function and gait. OBJECTIVE:To observe the effect of the effect of deep muscle stimulation combined with electromyographic biofeedback therapy on the spasm of the triceps surae and gait changes after stroke by using a digital muscle detector and three-dimensional gait analysis system. METHODS:A total of 72 patients who met the inclusion criteria were selected from the Rehabilitation Department of the First Affiliated Hospital of Guangdong Pharmaceutical University from October 2020 to October 2023.And they were enrolled and randomly divided into two groups(n=36 per group):a control group and a combined group.The control group received routine rehabilitation therapies,electromyographic biofeedback and pseudo deep muscle stimulation,while the combined group received true deep muscle stimulation treatment on the basis of the control group,five times per week,for 4 consecutive weeks.The oscillation frequency and dynamic stiffness of the affected gastrocnemius muscle,active range of motion of the ankle dorsiflexion muscle,electromyographic signal of the tibialis anterior muscle,Fugl-Meyer assessment of the lower limbs,and three-dimensional gait analysis parameters were statistically analyzed before and after treatment in two groups. RESULTS AND CONCLUSION:After treatment,oscillation frequency and dynamic stiffness values of the inner and outer sides of the affected gastrocnemius muscle in both groups of patients were significantly reduced compared with before treatment(P<0.05),and the combined group showed a more significant decrease compared with the control group(P<0.05).The active range of motion of the ankle dorsiflexion muscle,electromyographic signal of the tibialis anterior muscle,and Fugl-Meyer scores after treatment were significantly increased or improved compared with before treatment(P<0.05),while the combined group showed a more significant increase or improvement compared with the control group(P<0.05).In terms of gait parameters,the walking speed,frequency,and stride in both groups of patients were significantly increased compared with before treatment(P<0.05),while the combined group showed a more significant increase compared with the control group(P<0.05).The percentage time of support phase on the healthy side was shortened compared with before treatment(P<0.05),while the combined group showed a more significant decrease compared with the control group(P<0.05).In addition,there was no significant difference between the two groups except for the percentage of healthy side support(P>0.05).To conclude,the combination of deep muscle stimulation and electromyographic biofeedback can effectively alleviate triceps spasm in the short term after stroke,improve ankle dorsiflexion function,enhance lower limb motor function,and improve gait.The treatment effect is significant and worthy of clinical promotion and application.

Objective To examined gene mutations in thymic carcinoma (TC) patients and to explore prognostic correlates and potential targets for therapy. Methods We retrospectively included TC patients in Sichuan Cancer Hospital between January 2015 and Febuary 2021.Whole-exome sequencing was performed on tumor tissues from TC patients and their control peripheral blood samples, and the raw data were subjected to bioinformatics analysis and statistical analysis. Results We finally included 24 TC patients with 16 males and 8 females at a median age of 55 (42-74) years. The highest frequency of single nucleotide mutations in this cohort were in the TTN gene (42%), HSPG2 (29%), and OBSCN (29%). Higher frequency of copy number variations occurred in ZNF276 gene (54%, loss), BEND3 (50%, loss), DHODH (50%, loss), and VAC14 (50%, loss). Microsatellite instability (MSI) phenotype was found in 25% of the patients, and the mean tumor mutation burden (TMB) was 9.86. Conclusion This study is the first comprehensive analysis of the mutation profile of thymic carcinoma in China to date. The mutation frequencies of TTN, OBSCN, and ZNF276 genes were high. The biomarker analysis suggests that patients may benefit from immunotherapy and have a long effective survival.

Objective: To construct an evaluation index system of oral health literacy for children's parents, so as to provide an index system for the evaluation of oral health literacy for children's parents in China. Methods: The evaluation index system of oral health literacy for children's parents was designed based on literature review and semi-structured interview. Experts from oral prevention and pediatric oral medicine were invited to participate in two-round Delphi consultations. The indicators were scored and screened according to the importance, and the weight determined using analytic hierarchy process. The effectiveness of the consultation was evaluated by positive coefficient, authority coefficient and coordination coefficient. Results: Twenty-four experts participated in the consultation, including 6 males and 18 females. There were 21 experts with a master degree, 3 experts with a doctor degree, and 20 experts with vice senior professional titles and above. The recovery rates of the two rounds of consultations were 96.00% and 100.00%, the authority coefficients were 0.866 and 0.917, the Kendall's coefficient of concordance were 0.120 and 0.156 (both P<0.05), and the coefficient of variation was 0.15-0.38 and 0.03-0.17, respectively. The final evaluation index system included 3 primary indicators, 11 secondary indicators and 40 tertiary indicators. The primary indicators were basic knowledge and concepts related to oral health, promoting lifestyle and behaviors related to oral health, and maintaining basic skills related to oral health. Conclusion The evaluation index system of oral health literacy for children's parents has been established in this study and needs to be further applied and evaluated.

Objective To investigate the gray matter volume(GMV)changes and molecular basis underlying antipsychotic-induced weight gain(AIWG).Methods One hundred twenty-nine first-episode schizophrenia patients from October 2019 to December 2021 were enrolled in this study.Patients with≥7%weight gain(weight gain,WG)and patients with<3%weight changes(weight stable,WS)were studied.All patients underwent T1-weighted MRI scanning at baseline and after 8 week treatment.Transcriptome-neuroimaging correlations were used to investigate brain gene profiles from the Allen Human Brain Atlas and GMV changes induced by AIWG.Results Thirty-three patients with WG and 27 with WS completed the GMV measures.Compared with baseline,the WG group showed reduced GMV in right hippocampus,left basal ganglia,and right inferior parietal lobule,etc.and increased GMV in bilateral thalamus(P<0.05).The WS group showed reduced GMV in bilateral orbital gyrus,bilateral inferior frontal gyrus and bilateral hippocampus(P<0.05).These GMV changes in WG group were spatially correlated with expression levels of 354 genes,which were exclusively enriched in Cushing syndrome,neuroinflammation and glutamatergic signaling,and Pnoc+.Conclusion The study has demonstrated increased GMV in thalamus in schizophrenia patients with AIWG which may be associated with Cushing syndrome and Pnoc+.These findings may provide important insights into the molecular mechanisms of AIWG.

Objective:To analyze the risk factors of Epstein-Barr virus(EBV)infection after allogeneic hematopoietic stem cell transplantation(allo-HSCT)and its impact on survival.Methods:The clinical data of 347 patients who underwent their first allo-HSCT in our hospital from January 2014 to June 2021 were retrospectively analyzed.Patients were divided into EBV(n=114)and Non-EBV(n=233)groups according to whether they were infected with EBV.The incidence of EBV infection after allo-HSCT was calculated,and the risk factors of EBV infection were analyzed.Results:A total of 114(32.8％)patients presented EBV infection(all peripheral blood EBV-DNA were positive).EBV infection occurred in 88 patients within 100 days after transplantation,which accounted for 77.2％of all patients with EBV infection.5 cases(1.44％)were confirmed as post-transplant lymphoproliferative disorder(PTLD).The median onset time of patients was 57(7-486)days after transplantation.Multivariate analysis showed that the use of ATG/ATG-F,occurrence of CMV viremia,and grade Ⅲ-Ⅳ aGVHD were risk factors for EBV infection.Furthermore,compared to BUCY,the use of intensified preconditioning regimens containing FA/CA was significantly increased the risk of EBV infection.Conclusion:EBV infection is a common complication after allo-HSCT.Intensified preconditioning regimens,use of ATG/ATG-F,CMV viremia and grade Ⅲ to Ⅳ aGVHD increase the risk of EBV infection after allo-HSCT.

Objective:To explore the value of Plan-Do-Check-Act (PDCA) management model in improving the quality of breast ultrasound diagnosis.Methods:From January 1 to December 31, 2021, patients undergoing breast nodule surgery in the Union Hospital, Tongji Medical College, Huazhong University of Science and Technology were selected for breast ultrasound Breast Imaging Reporting and Data System (BI-RADS) classification diagnosis and follow-up. Using pathological results as the gold standard, the malignant rate of different BI-RADS grade and the coincidence rate of ultrasound diagnosis of breast cancer before the first treatment were analyzed. PDCA cycle management mode was introduced to analyze, learn and sort out the quality of breast ultrasound diagnosis. The same method was used to follow up the breast ultrasound diagnosis in the ultrasound department of our hospital from January 1 to December 31, 2022. The results of two follow-up visits were compared.Results:Compared with 2021, the malignancy rates of category 3 and 4a BI-RADS diagnosed by ultrasonic diagnosis of breast nodules in hospitals in 2022 were closer to the malignancy rates recommended by the classification guidelines of BI-RADS (all P<0.05). There was no significant difference in the malignant rate of BI RADS 4b, 4c and 5 types of nodules (all P>0.05). In 2022, compared with 2021, the ultrasound diagnosis coincidence rate before the first treatment of breast disease increased from 90.4%(1 592/1 761) to 95.9%(1 806/1 884). Conclusions:PDCA management mode is helpful to improve the classification and diagnosis quality of breast ultrasound BI-RADS, and better assist clinical diagnosis and treatment.
