Objective To evaluate the short-term effects of comprehensive health management interventions for stroke high-risk population screening on the prevention and treatment of ischemic stroke, and to provide reference and basis for improving and exploring health management and prevention strategies for stroke high-risk population. Methods From 2018 to 2022, 13 community health service centers in Jiading District, Shanghai were selected in the present study. Based on information push platform, stroke risk assessment and health intervention follow-up were conducted for community residents through convenience sampling. The residents were divided into a full course intervention group (intervention group) and a routine intervention group (control group) according to different health intervention measures and forms. The incidence of ischemic stroke in the two groups of survey subjects was tracked within 36 months. Results A total of 52144 subjects were included in the study. The total number of patients in the full course intervention group was 14227, with an incidence density of 577.32/100 000 (556.49/100 000-598.12/100 000), which was lower than that of the conventional intervention group (37 917), with an incidence density of 1 485.47/100 000 (1 464.99/100 000-1 505.94/100 000) (χ²=2490.212, P<0.001). The relative risk of the full course intervention group was 0.39, and the relative risk of stroke risk factors in the full course intervention group from low to high was 0.33, 0.43, 0.45, and 0.49, respectively. The incidence density of males in the full course intervention group was 660.76 (627.46/100 000 - 694.05/100 000), with a relative risk of 0.43, and the incidence density of female patients was 509.71/100 000 (483.37/100 000 - 536.05/100 000), with a relative risk of 0.35. The overall incidence density of the population under 62 years old gourp, 62-75 years old group and over 75 years old group was 197.45/100 000 (173.09/100 000 -221.80/100 000), 608.36/100 000 (580.19/100 000-636.54/100 000), and 1 025.06/100 000 (958.51/100 000-1 091.61/100 000), with relative risks of 0.51, 0.44, and 0.38, respectively. Conclusion Comprehensive health management measures can effectively reduce the short-term risk of ischemic stroke, and should be further promoted and improved to enhance the effectiveness of stroke prevention and control.

Objective: To construct a risk prediction model for pediatric metabolic dysfunction associated steatotic liver disease (MASLD), so as to provide practical tool for the early identification of high risk children. Methods: A healthy cohort of children in Southwest China was established from January 2021 to April 2025. A nested case-control study design was used to include 507 cases MASLD group and 507 cases in non MASLD group. Data on physical measurements, blood biochemical parameters, and liver ultrasound indicators were collected. Conditional Logistic regression was used to analyze the relationship between individual variables and MASLD, Lasso regression was applied for multivariable screening, and a high risk prediction model was constructed and presented in the form of a nomogram. Internal validation was performed using 10 repeated ten fold cross validations to assess model discrimination, accuracy, sensitivity, and specificity. Results: Logistic regression analysis showed that MASLD was associated with central obesity ( OR=22.11, 95%CI =15.62-31.29), apolipoprotein B ( OR=30.24, 95%CI =12.42-73.63), increased hepatorenal echo ( OR=326.00, 95%CI =183.87-578.01), hepatomegaly ( OR=24.98, 95%CI =16.66-37.46) (all P <0.05). The Lasso regression jointly selected 6 key variables, including hepatorenal echo, central obesity, hepatomegaly, right liver lobe inclination, body mass index, and alanine amino transferase. The results of cross validation showed that the average area under the curve (AUC) was 0.999 5, the average accuracy was 98.74%, and the sensitivity and specificity were 98.21% and 99.22% respectively, indicating a good predictive effect of the model. Conclusion The risk prediction model for high risk MASLD among children based on ultrasound and clinical indicators has good prediction effect, which is helpful for the early identification and risk stratification of pediatric MASLD.

OBJECTIVE To investigate the anti-inflammatory effect of electroacupuncture in mice with chronic obstructive pul-monary disease(COPD)and its underlying mechanisms.METHODS Forty C57BL/6 mice were randomly divided into normal group,model group,electroacupuncture(EA)group,vagotomy group,and vagotomy+EA group,with 8 mice in each group.Except for the normal group,all groups were exposed to cigarette smoke for 12 weeks to establish a COPD model.After model establishment,the vagotomy group and the vagotomy+EA group underwent left cervical vagotomy before EA.EA treatment was performed at the Feishu(BL13)and Zusanli(ST36)acupoints once daily for 20 minutes for a total of 14 days.After EA,the pulmonary ventilation function of the mice was detected by a pulmonary function analysis system;lung tissue pathology was observed by HE staining;the levels of inter-leukin(IL)-6,tumor necrosis factor-α(TNF-α),IL-10,and transforming growth factor-β(TGF-β)in lung tissue were detected by ELISA;the expression of CD86 and CD206 proteins in lung tissue was detected by Western blot;the distribution of F4/80+CD86+(M1 type)and F4/80+CD206+(M2 type)cells in lung tissue was determined by flow cytometry;the expression of CD86 and CD206 in lung tissue was observed by immunofluorescence.RESULTS Compared with the normal group,the model group showed significantly decreased lung function(P<0.01),obvious lung pathological damage,increased M1 proportion,IL-6,TNF-α,CD86 content and expression(P<0.05,P<0.01),and decreased M2 proportion,IL-10,TGF-β,CD206 content and expression(P<0.01).Compared with the model group,the EA group showed varying degrees of improvement in lung function and pathology;the M1 proportion,IL-6,TNF-α,and CD86 were reduced(P<0.05,P<0.01),while the M2 proportion,IL-10,TGF-β,and CD206 were increased(P<0.05,P<0.01).The vagotomy group showed worsened lung function and pathology,increased IL-6,TNF-α,and CD86 content and expression(P<0.05,P<0.01),and decreased IL-10,TGF-β,and CD206 content and expression(P<0.05,P<0.01).Compared with the EA group,the vagotomy+EA group showed increased M1 proportion,IL-6,TNF-α,and CD86 content and expression(P<0.01),and decreased M2 proportion,IL-10,TGF-β,and CD206 content and expression(P<0.05,P<0.01).CONCLUSION EA at Feishu(BL13)and Zusanli(ST36)acupoints can improve lung function and pulmonary inflammation in COPD mice,promoting the polarization of alveolar macrophages from M1 to M2,which is mediated by the vagus nerve.

Objective:Analyse the factors affecting whether the first two batches of centralized volume-based purchase of Proprietary Chinese Medicine were selected,the price difference and the rate of reduction,so as to provide a basis for improving the policy of centralized volume-based purchase of Proprietary Chinese Medicine.Methods:The first two batches of centralized volume-based purchase of Proprietary Chinese Medicine were selected for the study.Logistic regression was used to analyse the influencing factors of whether the selection was won or not.Multiple linear regression was used to analyse the influencing factors of price difference/reduction after being selected.Results:Proprietary Chinese Medicine with a high degree of acceptance by medical institutions and belonging to the category of essential medicines have a higher probability of being selected.The probability of selected products in the first batch of centralised purchase is greater for enterprises with a market share of more than 50%.In the first batch of centralized volume-based purchase of Proprietary Chinese Medicine,the price difference of injections and medicines belonging to the catalogue of essential medicines is greater.Price reductions were greater for those with low market share,low recognition by medical institutions,and a large number of enterprises in the A-competition unit and the same competition unit.In the second batch of centralised volume-based purchase of Proprietary Chinese Medicine,the price difference is greater for injections,and those with qualifications for the production of Chinese herbal medicines.the price reduction is greater in the B competitive unit.Conclusion:The centralized volume-based purchase of Proprietary Chinese Medicine has been both'quality-assured'and'price-reduced'.The centralized volume-based purchase of Proprietary Chinese Medicine has been gradually improved,and the tilt towards large enterprises has been reduced,so that the centralized volume-based purchase of Proprietary Chinese Medicine can achieve a'bottom price'.However,it is still necessary to start from the quality of identification,fair competition,and so on,and the centralized volume-based purchase of Proprietary Chinese Medicine fully linked to promote the centralized purchase of Traditional Chinese Medicine Decoction Pieces to a stable and far-reaching.

Objective:To evaluate the preventive effects of transcutaneous electrical acupoint stimulation (TEAS) on chronic pain after lumbar spine surgery.Methods:This was a secondary analysis conducted on the studies assessing the effect of TEAS on gastrointestinal function in patients undergoing lumbar spinal surgery. Fifty lumbar spinal stenosis patients of either sex, aged 50-75 yr, with a body mass index of 18.5-28.0 kg/m 2, of American Society of Anesthesiologists Physical Status cassification Ⅰ or Ⅱ, with expected operation time≥3 h, undergoing lumbar spinal surgery under general anesthesia, were enrolled and assigned into 2 groups ( n=25 each) using a random number table method: control group (C group) and TEAS group. In group C, stimulating electrodes were placed at the non-acupoint parts of the limbs, but no electrical stimulation was applied. In group TEAS, the bilateral Neiguan (PC6), Hegu (L14), Zusanli (ST36), Shangjuxu (ST37) and Xiajuxu (ST39) were stimulated with disperse-dense waves at a frequency of 2/100 Hz. The intensity of stimulation was the maximum current that patients could tolerate. The intervention was performed once a day for 30 min per session at 30 min prior to anesthesia induction and on postoperative days 1-7. Telephone follow-ups were conducted at 3, 6 and 12 months after surgery to record the occurrence of postoperative moderate-to-severe lower back pain and leg pain (Numerical Rating Scale score ≥4), and the Oswestry Disability Index (ODI) value and four-item neuropathic pain questionnaire scores. The pain-related medical visits and usage of nonsteroidal anti-inflammatory drugs were also recorded after surgery. Results:Three patients in each group were lost to follow-up. Compared with group C, the incidence of chronic low back pain was significantly decreased at 6-12 months after surgery, the ODI value and four-item neuropathic pain questionnaire scores were decreased at 12 months after surgery ( P<0.05), ODI value difference reached the minimal clinically important difference, the proportion of patients requiring medical visits due to postoperative pain and usage rate of nonsteroidal anti-inflammatory drugs were decreased at 6-12 months after surgery ( P<0.05), and no significant change in the incidence of chronic moderate-to-severe leg pain was found at each time period after surgery in group TEAS( P>0.05). Conclusions:TEAS can prevent the occurrence of chronic lower back pain and improve functional impairment in patients undergoing lumbar spine surgery.
