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.

ObjectiveTo analyze the changes in infectious disease reporting timeliness before and after the implementation of the National Infectious Disease Intelligent Surveillance and Early Warning Pre-position Software (hereinafter referred to as “the pre-position software”) at Baoding Maternal and Child Health Hospital, and to evaluate its effectiveness in shortening reporting time and improving reporting timeliness. MethodsCase data of infectious diseases submitted by Baoding Maternal and Child Health Hospital to the National Disease Prevention and Control System during January to July 2024 (pre-implementation) and January to July 2025 (post-implementation) were selected. Overall differences in reporting timeliness between the two periods were compared, and stratified comparative analyses were performed by month, weekdays versus weekends/holidays, disease type, and population characteristics. ResultsBefore and after the implementation of the pre-position software, the hospital reported 623 and 587 infectious disease cases, respectively. Among the total 1 210 cases, 49.26% (596/1 210) had a reporting timeliness of <10 h. The highest number of reported cases fell into the 1 to <5 h range, accounting for 31.24% (378/1 210). There was a statistically significant difference in the composition of reported cases by reporting timeliness for infectious diseases in the hospital before and after the use of the pre-position software (χ2=27.38, P<0.001). Compared with January to July 2024, the median reporting timeliness in January to July 2025 was shortened by 3.77 h, and the difference was statistically significant (Z=-3.50, P<0.001). In April (the fourth month after implementation), the median reporting timeliness was shortened by 9.00 h (Z=-3.17, P=0.002). On non-working days (Saturdays and Sundays), it was shortened by 7.64 h (Z=-5.69, P<0.001), and on public holidays, it was shortened by 7.21 h (Z=-3.71, P<0.001). For class C infectious diseases, the median time was shortened by 3.49 h (Z=-3.05, P=0.002). For scattered children, it was shortened by 4.95 h (Z=-3.78, P<0.001). All differences were statistically significant. ConclusionAfter the implementation of the pre-position software, the reporting timeliness for infectious diseases at Baoding Maternal and Child Health Hospital is shortened, with particularly notable reductions observed in April, on non-working days, for Class C infectious diseases, and for scattered children, indicating the reporting timeliness is improved. This study provides empirical references for the promotion and application of this software in medical institutions.
