Objective To explore the effect of early weight-bearing functional exercise on the postoperative function and satisfaction of patients with anterior talofibular ligament rupture.Methods Sixty patients with anterior talofibular ligament rupture admitted to Nanchang Hongdu Hospital of Traditional Chinese Medicine from June 2022 to June 2024 were included.According to the random number table method,the patients were divided into conventional group and early weight-bearing group,with 30 cases in each group.The American Orthopedic Foot and Ankle Society ankle-hindfoot scale(AOFAS-AHS)scores,Cumberland ankle instability tool(CAIT)scores,joint position sense active(JPSA)and joint position sense passive(JPSP)of ankle joint before and after the operation,and postoperative satisfaction of two groups of patients were compared.Results Six months after the operation,the AOFAS-AHS scores and CAIT scores of two groups were significantly higher than those before the operation,and the JPSA and JPSP were significantly lower than those before the operation(P＜0.05).The AOFAS-AHS score and CAIT score of patients of early weight-bearing group were significantly higher than those of conventional group,while the JPSA and JPSP were significantly lower than those of conventional group(P＜0.05).The satisfaction rate of patients of early weight-bearing group was significantly higher than that of conventional group(76.6％vs.66.6％,x2=6.205,P＜0.001).Conclusion Early weight-bearing functional exercise can improve the postoperative function of patients with anterior talofibular ligament rupture and enhance their postoperative satisfaction.

Objective:We conducted a quality analysis and a survey of current situation of portable blood glucose meters from hospitals and patient sources in Zhejiang Province..Methods:The study is a retrospective cross-sectional study that included 252 portable blood glucose meters, of which 35 portable blood glucose meters (4 in provincial hospitals, 29 in municipal hospitals, and 2 in county-level hospitals) selected for the "Zhejiang Province Portable Blood Glucose Meter Flight Quality Control Inspection" project in April 2023, 126 portable blood glucose meters collected for the "Zhejiang Hospital Portable Blood Glucose Meter Whole Hospital Comparison" project in January 2024, and 91 portable blood glucose meters collected from patients in the "Zhejiang Hospital Home Portable Blood Glucose Meter Convenience Service" project from 2021 to 2023. By comparing the blood glucose results with the reference analyzer, evaluate the qualification rate of portable blood glucose meters between hospitals and patients, imported and domestic brands, and analyze the distribution of blood glucose concentration intervals for unqualified portable blood glucose meters. Conduct a survey questionnaire on the use of portable blood glucose meters by patients to analyze their trust in the results, quality control execution rate, comparison awareness rate, and comparison execution rate.Results:The overall qualification rate of portable blood glucose meters in hospitals (95.7%) was higher than that of portable blood glucose meters use by patients (70.3%), and the difference was statistically significant ( χ 2=31.94 , P<0.001). Among the unqualified blood glucose meters, the unqualified blood glucose concentration is mainly concentrated in the high concentration range (65.9%). Among imported brands, the qualification rate of blood glucose meters from hospitals(99.3%) is higher than that from patients(74.0%), and the difference is statistically significant ( χ 2=36.97, P<0.001). Meanwhile, 75% of patients fully trust the detection results of the blood glucose meter, but its instrument qualification rate is 69%. The awareness rate of patients regarding the comparison of portable blood glucose meters is 73%, but the execution rate of quality control and standard comparison of portable blood glucose meters by patients is 0. Conclusion:The quality of portable blood glucose meters in Zhejiang Province is uneven, with the highest pass rate for portable blood glucose meters from hospitals. Patients have weak awareness of quality control and comparison of portable blood glucose meters.

Objective:Non-alcoholic fatty liver disease(NAFLD)is a common metabolic disorder in overweight and obese children,and its etiology and pathogenesis remain unclear,lacking effective preventive and therapeutic measures.This study aims to explore the association between whole blood copper,zinc,calcium,magnesium and iron levels and NAFLD in overweight and obese children aged 6 to 17 years,providing a scientific basis for the prevention and intervention of early NAFLD in overweight and obese children. Methods:A cross-sectional study design was used to collect relevant data from overweight and obese children who visited the Hunan Children's Hospital from January 2019 to December 2021 through questionnaire surveys.Fasting blood samples were collected from the subjects,and various indicators such as blood glucose,blood lipid,and mineral elements were detected.All children were divided into an overweight group(n=400)and a NAFLD group(n=202).The NAFLD group was divided into 2 subgroups according to the ALT level:A non-alcoholic fatty liver(NAFL)group and a non-alcoholic steatohepatitis(NASH)group.Logistic regression analysis was used to analyze the association between minerals(copper,zinc,calcium,magnesium,and iron)and NAFLD,NAFL and NASH. Results:A total of 602 subjects were included,of whom 73.6%were male,with a median age of 10(9,11)years,and a body mass index(BMI)of 24.9(22.7,27.4)kg/m2.The intergroup comparison results showed that compared with the overweight group,the NAFLD group had higher levels of age,BMI,diastolic blood pressure(DBP),systolic blood pressure(SBP),triglyceride(TG),low density lipoprotein(LDL),alanine transaminase(ALT)and aspartate aminotransferase(AST),and lower level of high density lipoprotein(HDL).The NAFL group had higher levels of age,BMI,DBP,SBP,ALT,and AST,and lower levels of HDL compared with the overweight group.The levels of age,BMI,DBP,SBP,TG,LDL,ALT,and AST of NASH were higher than those in the overweight group,while the level of HDL was lower than that in overweight group(all P<0.017).After adjusting for a variety of confounders,the OR of NAFLD for the highest quantile of iron was 1.79(95%CI 1.07 to 3.00)compared to the lowest quantile,and no significant association was observed between copper,zinc,calcium,and magnesium,and NAFLD.The subgroup analysis of NAFLD showed that the OR for the highest quantile of iron in children with NAFL was 2.21(95%CI 1.26 to 3.88),while no significant association was observed between iron level and NASH.In addition,no significant associations were observed between copper,zinc,calcium,and magnesium levels and NAFL or NASH. Conclusion:High iron level increases the risk of NAFLD(more likely NAFL)in overweight and obese children,while copper,zinc,calcium,magnesium,and other elements are not associated with the risk of NAFLD in overweight and obese children.

Objective:Non-alcoholic fatty liver disease(NAFLD)has significant genetic susceptibility.Adipocytokines play a crucial role in NAFLD development by participating in insulin resistance and hepatic steatosis.However,the association between adipocytokine pathway genes and NAFLD remains unclear.This study aims to explore the association of gene polymorphisms in the adipocytokine pathway and their interactions with NAFLD in obese children. Methods:A case-control study was conducted,dividing obese children into NAFLD and control groups.Peripheral venous blood(2 mL)was collected from each participant for DNA extraction.A total of 14 single nucleotide polymorphisms(SNP)in the adipocytokine pathway were genotyped using multiplex PCR and high-throughput sequencing.Univariate and multivariate Logistic regression analyses were used to assess the association between SNP and NAFLD in obese children.Dominant models were used to analyze additive and multiplicative interactions via crossover analysis and Logistic regression.Generalized multifactor dimensionality reduction(GMDR)was used to detect gene-gene interactions among the 14 SNPs and their association with NAFLD in obese children. Results:A total of 1 022 children were included,with 511 in the NAFLD group and 511 in the control group.After adjusting for age,gender,and BMI,multivariate Logistic regression showed that PPARG rs1801282 was associated with NAFLD in the obese children in 3 genetic models:heterozygote model(CG vs CC,OR=0.58,95%CI 0.36 to 0.95,P=0.029),dominant model(GG+CG vs CC,OR=0.62,95%CI 0.38 to 1.00,P=0.049),and overdominant model(CC+GG vs CG,OR=1.72,95%CI 1.06 to 2.80,P=0.028).PRKAG2 rs12703159 was associated with NAFLD in 4 genetic models:heterozygous model(CT vs CC,OR=1.51,95%CI 1.10 to 2.07,P=0.011),dominant model(CT+TT vs CC,OR=1.50,95%CI 1.10 to 2.03,P=0.010),overdominant model(CC+TT vs CT,OR=0.67,95%CI 0.49 to 0.92,P=0.012),and additive model(CC vs CT vs TT,OR=1.40,95%CI 1.07 to 1.83,P=0.015).No significant multiplicative or additive interaction between PPARG rs1801282 and PRKAG2 rs12703159 was found in association with NAFLD.GMDR analysis,adjusted for age,gender,and BMI,revealed no statistically significant interactions among the 14 SNPs(all P>0.05). Conclusion:Mutations in PPARG rs1801282 and PRKAG2 rs12703159 are associated with NAFLD in obese children.However,no gene-gene interactions among the SNP are found to be associated with NAFLD in obese children.

Objective:To explore any effect of supplementing telerehabilitation with wearable technology on the upper limb functioning and activity of stroke survivors.Methods:Fifty family-based stroke survivors were randomly divided into an experimental group and a control group, each of 25. In addition to routine medication, the control group was given routine rehabilitation guidance at home, while the experimental group was guided using telerehabilitation and wearable technology. The guidance lasted 20 minutes, 5 days a week for 8 weeks. Before and after the intervention, both groups′ upper limb motor functioning was evaluated using the Fugl-Meyer upper extremity assessment (FMA-UE). The modified Ashworth scale (MAS) was used to quantify hemiplegic muscle spasms, and ability in the activities of daily living was quantified using the modified Barthel index (MBI). A wireless motion capture system generated average trace error (ATE) and test execution time data.Results:There were no significant differences between the two groups before the experiment. After the 8 weeks, significant improvement was observed in both groups′ average FMA, MAS and MBI scores, with those of the experimental group significantly better, on average, than those of the control group. There was also a significant improvement in the average ATE and time data in both groups, with significantly better results in the treatment group.Conclusions:Telerehabilitation based on wearable technology can distinctly improve upper limb motor function and ability in the activities of daily living after a stroke.

Objective:This study evaluates the performance of chemiluminescence assay, which is designed to detect Hepatitis D Virus (HDV) Immunoglobulin G (IgG) antibodies.Methods:A comparative analysis was conducted among chemiluminescence anti-HDV IgG reagent, the magnetic particle-based domestic reagent A and domestic reagent B, and the Robo Gene HDV RNA kit, using 1909 HBsAg-positive plasma samples. This comparison aimed to delineate clinical specificity and detection accuracy. The anti-HDV IgG reagent precision was assessed at three different concentration levels following the Clinical Laboratory Standards Institute EP5-A2 guidelines. The specificity of the assay was validated using 200 HAV IgM positive, 545 HBsAg-positive but anti-HDV IgG-negative, 350 anti HCV positive plasma samples and 200 healthy human blood samples. Additionally, a concordance study was conducted with 545 HBsAg-positive and 37 anti-HDV IgG-positive plasma samples, comparing the anti-HDV IgG reagent against reagent A.Results:1 909 HBsAg-positive plasma samples were tested using 3 anti HDV IgG reagent and 1 HDV RNA reagent, 19 samples were identified as anti-HDV IgG-positive. The anti-HDV IgG demonstrated superior accuracy and specificity. The assay exhibited excellent precision, with intra-assay coefficient of variation (CV) values ranging from 1.57% to 4.30%, and inter-assay CV values between 1.71% and 4.67% for detecting samples at high, medium, and low concentration levels. Concordance with Reagent A showed consistent results in both positive and negative detections.Conclusion:In this study, the anti-HDV IgG reagent (chemiluminescence method) displayed outstanding specificity in detecting clinical samples and exhibited a high conformity rate with commercialized reagents, making it potentially suitable for screening anti-HDV IgG in HBsAg-positive samples.
