ObjectiveTo observe the effect of functional pelvic floor muscle training on pelvic floor muscle function, incontinence symptoms and quality of life in female patients with stress urinary incontinence (SUI). MethodsFrom February, 2024 to July, 2025, 40 female patients with SUI were recruited from Beijing Bo'ai Hospital and advertisements. They were randomly divided into control group (n = 20) and experimental group (n = 20). The control group received conventional pelvic floor muscle contraction and relaxation training, and the experimental group received functional pelvic floor muscle contraction and relaxation training, for eight weeks. The data of pelvic floor muscle strength, pelvic floor muscle surface electromyography (sEMG), 1-hour urine pad test and Incontinence Quality of Life questionnaire (I-QOL) were collected before and after training. The compliance rate was counted after training. ResultsOne case dropped down in the control group and three cases dropped down in the experimental group. After treatment, the pelvic floor muscle strength increased in both groups (|Z| > 3.317, P < 0.01), the pre-resting average value, sustained contraction average value and durable contraction average value of sEMG improved in the control group (|t| > 2.731, P < 0.05), the mass of 1-hour urine pad significantly reduced (t > 9.215, P < 0.001) and the I-QOL score significantly increased (|t| > 13.229, P < 0.001) in both groups; compared with the control group, the pelvic floor muscle strength significantly increased (Z = -2.281, P = 0.023), the mass of 1-hour urine pad significantly reduced (t = 4.215, P < 0.001), the I-QOL score significantly increased (t = -4.501, P < 0.001), and the compliance rate significantly increased (Z = -2.798, P < 0.01) in the experimental group . ConclusionFunctional pelvic floor muscle training can significantly improve pelvic floor muscle strength, incontinence symptoms and quality of life in female patients with SUI.

ObjectiveTo explore the potential mechanism underlying electroacupuncture therapy with the midnight-noon ebb-low method with hour-prescription for chronic obstructive pulmonary disease （COPD） with lung-qi deficiency syndrome from the perspective of brain and muscle basic helix-loop-helix ARNT-like 1 （BMAL1） as well as neutrophil extracellular traps （NETs）. MethodsThe experiment was conducted in two phases. For the therapeutic effectiveness observation， 24 rats were randomly allocated into control group 1， model group 1， midnight-noon electro-acupuncture group 1 and conventional electro-acupuncture group， with 6 rats per group. Rat models of COPD with lung-qi deficiency syndrome were established via cigarette smoke exposure combined with intratracheal instillation of lipopolysaccharide （LPS）. After successful modelling， rats in midnight-noon electro-acupuncture group 1 received electro-acupuncture at acupoints "Taiyuan （LU 9）"， "Feishu （BL 13）" and "Zusanli （ST 36）" during 05：00—07：00， 30 minutes per treatment once every other day for 14 consecutive days （7 sessions in total）. Rats in the conventional electro-acupuncture group received identical electroacupuncture manipulation at random daytime hours （08：00—18：00）. Pulmonary function parameters including forced expiratory volume in 0.3 second （FEV_0.3）， forced vital capacity （FVC） and FEV_0.3/FVC ratio were detected. Pulmonary histopathological changes were observed via hematoxylin-eosin （HE） staining. Plasma levels of pro-inflammatory factors interleukin-1β （IL-1β） and tumor necrosis factor-α （TNF-α）， as well as pulmonary reactive oxygen species （ROS） content， BMAL1 protein expression and the levels of neutrophil extracellular traps （NETs） biomarkers such as myeloperoxidase （MPO）， neutrophil elastase （NE）， and citrullinated histone H3 （CitH3） in lung tissue were determined. For the mechanistic verification phase， 36 rats were divided into control group 2， model group 2， midnight-noon electro-acupuncture group 2， overexpression empty group， overexpression BMAL1 group and overexpression with midnight-noon electro-acupuncture group， with 6 rats in each group. At the 5th week of model construction， rats in the overexpression BMAL1 group and overexpression with midnight-noon electro-acupuncture group received intratracheal instillation of 100 μl adenoviral suspension carrying overexpressed Bmal1 gene. Rats in the overexpression empty group were injected with an equal titer and equal volume of blank adenovirus without the Bmal1 coding sequence into the lung at the identical time point. Midnight-noon electro-acupuncture group 2 and overexpression with midnight-noon electro-acupuncture group were consistent with the aforementioned protocol. Finally， pulmonary levels of MPO， NE and CitH3 were measured in all groups. ResultsCompared with the control group 1， the model group 1 exhibited decreased FEV_0.3， FVC and FEV_0.3/FVC ratio， elevated plasma IL-1β， TNF-α and pulmonary ROS levels， downregulated lung BMAL1 protein expression， and increased contents of MPO， NE and CitH3 （all P＜0.05）； typical NETs-like structures with sparse granular substances attached to fibrous networks were observed under scanning electron microscopy； HE staining revealed damaged alveolar architecture accompanied by inflammatory cell infiltration. Compared with model group 1， both the midnight-noon electro-acupuncture group 1 and conventional electro-acupuncture group achieved obvious improvements in all above indicators， with superior therapeutic effects in midnight-noon electro-acupuncture group 1 （P＜0.05）. Consistently， midnight-noon electro-acupuncture group 1 showed more prominent alleviation of NETs-like structure formation and lung pathological injury compared to the conventional electro-acupuncture group. Mechanistic validation results demonstrated that compared with model group 2， the average optical density of MPO as well as the protein levels of MPO， NE and CitH3 were markedly reduced in midnight-noon electro-acupuncture group 2， overexpression BMAL1 group and overexpression with midnight-noon electro-acupuncture group （P＜0.05）； furthermore， these parameters were significantly lower in the overexpression with midnight-noon electro-acupuncture group than in midnight-noon electro-acupuncture group 2 （P＜0.05）. ConclusionElectro-acupuncture based on the midnight-noon ebb-low method with hour-prescription may alleviate pulmonary inflammation in COPD by upregulating the expression of clock protein BMAL1 and inhibiting excessive accumulation of NETs in lung tissue.

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.

AIM:To investigate the potential mechanism of neutrophil extracellular traps(NETs)in the pla-centa during the pathogenesis of preeclampsia(PE).METHODS:Differential neutrophil infiltration in PE versus normo-tensive placentas was assessed using placental transcriptome sequencing data.Single-cell sequencing analysis of GSE173193 dataset was conducted to evaluate the expression of NETs formation-related genes in neutrophils from PE pla-centa and control placenta.Immunofluorescence and ELISA were used to measure NETs levels in placental tissues.Fol-lowing NETs generation and treatment of human extravillous trophoblast(EVT)HTR8/Svneo strain with NETs,RNA se-quencing was utilized to identify potential signaling pathways through which NETs regulate trophoblast function.RE-SULTS:Neutrophil infiltration,and expression of NETs formation critical genes,MPO(myeloperoxidase)and ELANE(elastase,neutrophil expressed),in neutrophils were significantly increased in PE placentas compared with controls.The level of NETs was elevated in PE placentas as well.The NETs significantly inhibited the migration of HTR8/Svneo cells.Disrupted F-actin arrangement,aggregate formation,and reduced paxillin expression were observed in NETs-treated HTR8/Svneo cells.Single-cell sequencing analysis revealed that focal adhesion and stress fiber pathways were down-regu-lated in the EVT of PE placenta.CONCLUSION:Neutrophil infiltration and NETs formation were increased in PE.The NETs may inhibit EVT migration by inducing stress fiber disassembly and down-regulating paxillin expression,thereby dis-rupting cytoskeletal organization and focal adhesion formation.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

Objective:To analyze the correlation between serum uric acid-to-high-density lipoprotein cholesterol ratio (UHR) and risk of all-cause death or cardiovascular disease (CVD) death among urban and rural elderly in Beijing.Methods:Based on the Beijing Healthy Aging Cohort Study, 9 022 participants with complete baseline data were enrolled, and their survival and death outcomes were followed up. Multivariable Cox proportional hazard regression model were used to analyze the associations between the UHR level and the risks of all-cause mortality and CVD mortality.Results:As of March 31, 2021, the median follow-up time M( Q1, Q3) was 6.18 (5.36, 6.75) years. There were 1 166 all-deaths, with a death density of 19.26 per 1 000 person-years, and 562 CVD deaths, with a death density of 9.28 per 1 000 person-years. After adjusting sociodemographic characteristics and lifestyle factors, multivariable Cox proportional hazard regression model showed that the risk of all-cause mortality increased by 3% ( HR=1.03, 95% CI: 1.02-1.04) and the risk of CVD mortality increased by 4% ( HR=1.04, 95% CI: 1.02-1.06) for every 1% increase in UHR. Compared with the T1 group of UHR tertiles, the T3 group had a 42% increase in the risk of all-cause death ( HR=1.42, 95% CI: 1.22-1.66) and a 53% increase in the risk of CVD death ( HR=1.53, 95% CI: 1.21-1.94). Conclusions:The UHR level is significantly associated with the risks of all-cause mortality and CVD mortality among urban and rural older adults in Beijing. The UHR level may be one of the potential predictors of death risk in community-dwelling older adults.
