Objective To investigate muscle mass reduction and the effect of exercise training intervention in non-obese patients with type 2 diabetes (T2DM). Methods A total of 324 non-obese patients with T2DM admitted to the First Affiliated Hospital of Xinjiang Medical University were enrolled from February 2023 to February 2025. Dual-energy X-ray absorptiometry was adopted to detect and analyze the data of appendicular skeletal muscle index (ASMI). Non-obese T2DM patients were classified into an observation group (n=162, receive sports training intervention) and a control group (n=162, receiving routine exercise intervention) by adopting random number grouping criteria. Both groups were intervened for 3 months. The muscle mass indicators [ASMI, body mass index (BMI), and body fat rate], exercise ability [6-minute walking distance (6MWD), grip strength, and one-leg standing time], metabolic indicators [fasting plasma glucose (FPG), glycosylated hemoglobin (HbA1c), and homeostasis model assessment insulin resistance index (HOMA-IR)], and quality of life [Diabetes Quality of Life Scale (DQOL)] were compared between the two groups to evaluate the effectiveness of sports training intervention. Results A total of 324 non-obese T2DM patients were enrolled, including 123 cases with reduced muscle mass (37.96%). There were no significant differences in the baseline data and the proportion of patients with muscle mass reduction between the two groups before intervention (P>0.05). After intervention, the ASMI, 6MWD, grip strength, and one-leg standing time in the observation group were higher or longer than those of the control group (P<0.05), while the body fat rate, FPG, HbA1c, HOMA-IR and DQOL scores were lower than those of the control group (P<0.05). Conclusion The incidence of muscle mass reduction is relatively high among non-obese T2DM patients, and exercise training intervention has significant effects on improving muscle mass, metabolic status, exercise capacity and quality of life in non-obese T2DM patients.

Methods: On May 14, 2025, AEFI case data and vaccination data for the domestic bivalent HPV vaccine among female students in primary, junior, and senior high schools in Hebei Province from 2022 to 2024 were collected from the China Disease Control and Prevention Information System and the Hebei Provincial Immunization Program Information Management System, respectively. Statistical analysis was performed by using descriptive and analytical epidemiological methods, with intergroup comparisons conducted by using the Chi square test or Fisher s exact probability test. Results: From 2022 to 2024, a total of 817 900 doses of the domestic bivalent HPV vaccine were administered to female students in primary, junior, and senior high schools in Hebei Province. A total of 68 AEFI cases were reported, comprising 57 common vaccine reactions, 7 rare vaccine reactions, 3 coincidental events, and 1 psychogenic reaction. The overall AEFI reporting rate was 8.31 per 100 000 doses, 4 cases (2.30/100 000 doses), 31 cases (8.73/100 000 doses), and 33 cases (11.41/100 000 doses) were reported in 2022, 2023, and 2024, respectively, with a statistically significant difference across years ( χ 2=10.97, P <0.01). The reporting rates for common and rare vaccine reactions were 6.97 per 100 000 doses and 0.86 per 100 000 doses, respectively. The AEFI reporting rates were 15.14 per 100 000 doses among primary school girls and 8.20 per 100 000 doses among secondary school girls, though the difference was not statistically significant (Fisher s exact test, P =0.30). The reporting rate was higher after the first dose (10.91/100 000 doses) than after the second dose (5.96/100 000 doses; χ 2=5.85, P =0.02).The second quarter recorded the highest AEFI reporting rate at 11.21 per 100 000 doses. The majority of AEFI cases (56 cases, 82.35%) occurred within 24 hours post vaccination. Conclusion The domestic bivalent HPV vaccine demonstrates a favorable safety profile among female students in Hebei Province, with a low overall AEFI reporting rate that consisted predominantly of general reactions and occasional cardiac related reactions.

Objective To understand the clinical applicability and implementation of expert consensus on the implementation and removal of protective restraints in psychiatry,and to provide references for promoting the standardized practice of psychiatric protective restraints and updating the consensus.Methods By the convenience sampling method,a questionnaire survey was conducted among nurses from 480 hospitals in 30 provinces from June 15 to July 15,2024.The survey was conducted using the instrument for evaluating clinical applicability of guide-lines(version 2.0)and a self-compiled questionnaire on the clinical implementation of the restraint consensus.Results A total of 7,844 valid questionnaires were collected,with a valid questionnaire recovery rate of 93.78％.The results of clinical applicability scoring showed that the consensus had the lowest availability score(64.72％)and the highest acceptability score(76.74％).The results showed that nurses' receiving training and the level of their hospitals were the main influencing factors for scores in various dimensions(P＜0.05).4,774 participants(87.42％)believed that the application of consensus could enhance the standardization of nurses' restraint operations.The safety rate of the restraint consensus was 79.51％,and the economic ratio was 76.87％.Among the evaluators,1,739(22.17％)believed that there were implementation obstacles in the consensus.Conclusion The clinical applicability of the consensus is relatively good,and the application of the consensus helps to improve the standardization of clinical operations.In the future,efforts should be made to strengthen the promotion and training of the consensus,develop hierarchical promotion strategies according to the characteristics of medical institutions,and improve the quality of evidence for the consensus,so as to further enhance the clinical application effect of the consensus.

Objective: To observed the effect of a curcumin-based vaginal gel combined with electroporation for the treatment of vulvovaginal candidiasis (VVC) caused by Candida albicans. Methods: Temperature-sensitive in situ gels (ISG) were prepared using poloxamers 407 and 188 as matrices. The mass ratio of poloxamer 407 and poloxamer 188 was 7:1 with a gelation temperature of approximately 29°C and gelation time of 2.5 min. Results: Electroporation increased the transmucosal permeability of the model drug, doxorubicin and improved the antifungal effects of curcumin. In vitro antifungal experiments showed that the number of fungal colonies in curcumin ISG combined with electroporation was lower than that in pure curcumin ISG. In vivo pharmacodynamic experiments showed that, compared to the model group, curcumin ISG with electroporation inhibited the growth of C. albicans, alleviated vaginal mucosal edema, and reduced the inflammatory response. Conclusion Curcumin ISG combined with electroporation has substantial potential for the efficient clinical treatment of VVC.

Objective:To explore the clinical and genetic characteristics of X-linked intellectual disability associated with HUWE1 gene variants.Methods:A cases series study retrospectively analyzed the clinical data of 6 children with HUWE1 gene variants. The children were identified from the Third Affiliated Hospital of Zhengzhou University, the First Affiliated Hospital of Zhengzhou University, the First Affiliated Hospital of Henan University of Chinese Medicine, and Guangzhou Women and Children′s Medical Center of Guangzhou Medical University between April 2021 and July 2023.The data included sex, age, dysmorphic features, intellectual and motor development, seizure history, neuroimaging findings, family history, and genetic results was analyzed.Results:A total of 6 children, including 5 boys and 1 girl. The age of onset ranged from 1 day to 3 years. All children presented with varying degrees of intellectual disability, with or without motor developmental delay. Dysmorphic features were observed in 4 children, including microcephaly in 3 children. Short stature were observed in 3 children. One child was diagnosed with autism spectrum disorders and 1 child had seizures. Two boys had relevant maternal family histories of febrile seizures and mild intellectual disability, respectively. Abnormal neuroimaging findings were presented in 4 children, including cerebral dysplasia (1 child), prominent supratentorial ventricles (1 child), and mild white matter demyelination (2 children). Whole-exome sequencing identified 5 missense variants and 1 in-frame deletion variant. Five variants were novel and previously unreported (c.12290C>T, c.12701T>C, c.9875C>T, c.9641A>T and c.10313_10315del). The variants in 4 boys were maternally inherited, while the remaining 2 children had de novo variants. The child with the in-frame deletion variant (c.10313_10315del) presented with the most severe phenotype, exhibiting symptoms from 1 day of age, absent cognitive development, feeding difficulties, and congenital laryngeal chondrodysplasia. He was lost to follow-up at 3 months of age after treatment was withdrawn. The age at the last follow-up for the remaining 5 children ranged from 2 years and 10 months to 17 years. A boy with seizures died at 2 years and 10 months of age. The remaining 4 children were able to walk independently at the last follow-up, although their developmental progress was slow. Conclusions:HUWE1 gene related X-linked intellectual disability is characterized by varying degrees of developmental delay and intellectual disability, frequently accompanied by microcephaly, short stature, and occasionally by seizures and autism spectrum disorders. Missense variants are more common and the in-frame deletion variant appears to be associated with a particularly severe phenotypic presentation.

Objective:To investigate the bone augmentation effects of domestic decellularized porcine small intestinal submucosa (PSIS) absorbable biomembrane and domestic bovine pericardium tissue (BPT) absorbable biomembrane in guided bone regeneration (GBR) for single-tooth implantation in diabetic patients.Methods:A prospective case-control study was conducted with 48 diabetic patients who received single-tooth implant restoration at the Department of Prosthodontics, School of Stomatology. The Fourth Military Medical University, between January 2023 and January 2024. Patients were randomly assigned to the study group (PSIS group) and the control group (BPT group) using a random number table, with 24 patients in each group. GBR was performed simultaneously with the implant surgery. Cone-beam CT was used to compare the buccal-side horizontal bone gain at 6 months post-operation between the two groups. Wound healing was evaluated at 1 and 4 weeks post-operation using wound healing scores.Results:At 6 months post-operation, the buccal-side horizontal bone gain at 2 mm below the implant abutment in the study group [69.1 (55.2, 82.4) mm] and the control group [71.4 (59.8, 77.0) mm] showed no statistically significant difference ( Z=-0.25, P=0.805). The wound healing scores at 1 and 4 weeks post-operation in the study group did not differ significantly from those in the control group at the same time points (1 week: Z=-0.49, P=0.627; 4 weeks: Z=-0.61, P=0.539). Conclusions:The use of two types of domestic absorbable collagen membranes for GBR in single-tooth implantation in diabetic patients showed comparable buccal-side horizontal bone gain effects at 6 months post-operation and similar clinical outcomes for wound healing at 1 and 4 weeks post-operation in both groups. The GBR effects of PSIS and BPT are similar.

Objective To investigate the prevalence status and influencing factors of metabolic syndrome (MS) in adult patients with hypopituitarism (HP) during hospitalization. Methods The data of adult HP patients who received treatment in the hospital were collected from March 2021 to March 2024. The prevalence status of MS in adult HP patients was counted, and logistic regression analysis was adopted to analyze the influencing factors of MS in adult HP patients. Results Among the 308 adult HP patients in this study, 121 cases developed MS and 187 cases did not develop MS, and they were included in the MS group (n=148) and the non-MS group (n=232). The incidence of MS in adult HP patients was 38.95% (148/380). Compared with the non-MS group, the levels of high-density lipoprotein cholesterol, serum total cholesterol and low-density lipoprotein cholesterol in the MS group were higher, the waist circumference was larger, and the growth hormone was lower (P<0.05). After logistic regression analysis, it was found that high-density lipoprotein cholesterol (OR=1.069, 95%CI: 1.010-1.132, P=0.021), total serum cholesterol (OR=1.065, 95%CI: 1.014-1.119, P=0.012), low-density lipoprotein cholesterol (OR=1.055, 95%CI: 1.005-1.108, P=0.031), waist circumference (OR=1.063, 95%CI: 1.006-1.123, P=0.030) and growth hormone (OR=1.077, 95%CI: 1.019-1.138, P=0.009) could independently affect the occurrence of MS in adult HP patients (P<0.05). Conclusion Adult HP patients during hospitalization are often complicated with MS. High-density lipoprotein cholesterol, serum total cholesterol, low-density lipoprotein cholesterol, waist circumference, and growth hormone are factors affecting the occurrence of MS in adult HP patients.
