Objective:To investigate the influencing factors of participation in free health check-up among community residents.Methods:From 2012 to 2022 Xinzhuang Community Health Service Center of Shanghai Minhang district provided 5 free health check-up for local residents, once every 2 years. Among 5 904 eligible community residents with a mean age of (66.01±5.87) years, 682 (11.55 %), 912 (15.45 %), 842 (14.26 %), 934 (15.82 %), 1 061 (17.97 %) and 1 473 (24.95 %) participated in 5, 4, 3, 2, 1 and 0 health check-ups during 10 years, respectively. The influencing factors of participant frequency were analyzed with multivariate logistic regression model.Results:Multivariate logistic regression analysis showed that age 65 years and above ( OR=0.685, 95% CI: 0.625-0.751, P<0.001), exercising once a week or more ( OR=1.142, 95% CI: 1.031-1.266, P=0.011), and underweight ( OR=0.665, 95% CI:0.496-0.891, P=0.006) were independent factors influencing the participant in free health check-up among community residents. Conclusion:Community residents with older age or underweight are less likely to participate free health check-up, while those with frequent exercise like to participate.

Objective:To explore the risk factors of all-cause death in hypertensive patients in the community.Methods:A cohort of 4 049 hypertensive patients who participated in annual health checkups at Xinzhuang Community Health Service Centre of Shanghai Minhang district from January to December 2012 were enrolled in the study. All-cause death was the endpoint event of this study, and patients were divided into a fatal group and a survival group. The collection date for the endpoint event was December 2022. A multivariate Cox regression model was used to analyse the independent risk factors of all-cause mortality among hypertensive patients in the community.Results:Among 4 049 patients aged (67.9±7.1) years, 1 856 (45.8%) were males. There were 610 cases in the fatal group and 3 439 cases in the survival group. Multivariate Cox proportional regression showed that male gender ( HR=1.446, 95% CI: 1.200-1.742, P<0.001), older age ( HR=1.130, 95% CI: 1.118-1.143, P<0.001), higher waist-to-height ratio ( HR=8.117, 95% CI: 2.235-29.481, P=0.001), positive urinary protein ( HR=2.974, 95% CI: 2.202-4.016, P<0.001), high fasting blood glucose ( HR=1.070, 95% CI: 1.012-1.131, P=0.017), and history of stroke ( HR=1.819, 95% CI: 1.414-2.340, P<0.001) were independent risk factors for all-cause mortality in hypertensive patients, while exercise≥1/week ( HR=0.816, 95% CI: 0.668-0.996, P=0.046) and taking lipid-lowering medications ( HR=0.459, 95% CI: 0.223-0.947, P=0.035) were protective factors for all-cause mortality. Conclusion:For hypertensive patients, male gender, older age, higher waist-to-height ratio, positive urinary protein, high fasting blood glucose, and history of stroke are risk factors for all-cause mortality, while exercise≥1/week and taking lipid-lowering medications are protective factors.

Objective:To analyze the association between sleep status and ambulatory blood pressure monitoring indicators in community-dwelling hypertensive patients.Methods:It was a cross sentional study. Hypertensive patients who underwent 24-hour ambulatory blood pressure monitoring from May 2021 to April 2023 in Shanghai Xinzhuang Town were enrolled. The demographic information and sleep status of patients were obtained from the questionnaire. A TM-2430 blood pressure monitor was used to measure 24-hour ambulatory blood pressure, and the relevant indicators, including blood pressure level and blood pressure coefficient of variation were documented. The association between sleep status and blood pressure indicators was analyzed with multivariate linear regression model.Results:A total 1 135 patients aged (65.07±12.61) years were enrolled, and 473 (41.67%) of whom were males. The sleep time was<7 hours in 76 cases, 7- 8 hours in 219 cases and >8 hours in 840 cases; the bedtime was earlier than 22∶00 in 415 cases, between 22∶00 and 23∶00 in 474 cases and later than 23∶00 in 246 cases; the wake-up time was before 6∶00 in 230 cases, between 6∶00 and 7∶00 in 521 cases and after 7∶00 in 384 cases. Multivariate linear regression analysis showed that after controlling for gender and age, the sleep time was negatively associated with diurnal, noctumal and 24-hour diastolic blood pressure levels (all P<0.05), and positively associated with diurnal and noctumal systolic blood pressure coefficient of variation, noctumal diastolic blood pressure coefficient of variation, and 24-hour systolic blood pressure coefficient of variation (all P<0.05).The bedtime was positively associated with diurnal, noctumal and 24-hour diastolic blood pressure (all P<0.05), diastolic blood pressure (all P<0.05); and negatively associated with diurnal systolic blood pressure coefficient of variation, diurnal diastolic blood pressure coefficient of variation, noctumal systolic blood pressure coefficient of variation, 24-hour systolic blood pressure coefficient of variation, and 24-hour diastolic blood pressure coefficient of variation (all P<0.05). The wake-up time was positively associated with diurnal systolic blood pressure, diurnal, noctumal and 24-hour diastolic blood pressure (all P<0.05), and positively associated with diurmal systolic blood pressure and diastolic blood pressure (both P<0.05). Conclusion:Sleep status is closely associated with ambulatory blood pressure monitoring indicators in community-dwelling hypertensive patients.

OBJECTIVE: To assess the clinical effectiveness of acupoint application (AP) of Guan Xin Su He Pill (, GXSHP) for patients with chronic stable angina pectoris (CSAP). METHODS: This study was carried out in 3 local hospitals in Chengdu, China. After baseline evaluation, eligible patients were randomly assigned to the placebo application for acupoints (PAA) group or the herbal application for acupoints (HAA) group. Patients in the HAA group underwent AP with herbal powder, which was mainly GXSHP, and patients in the PAA group underwent AP with sham drugs. For each treatment session, unilateral acupoints including Neiguan (PC 6), Danzhong (RN 17), Xinshu (BL 15) and Jueyinshu (BL 14), were stimulated for both groups. AP was performed 3 times a week with a 2-day interval for 4 weeks. The primary outcome was the frequency of angina pectoris attacks per week, while the secondary outcomes included angina pain intensity measured by the Visual Analogue Scale (VAS), dose of rescue oral drugs (nitroglycerin), scores on the Seattle Angina Questionnaire (SAQ), Self-Rating Anxiety Scale scores (SAS) and Self-Rating Depression Scale scores (SDS). Clinical outcomes were measured at week 0, 4 and 8. The safety of AP of GXSHP treatment for CSAP were assessed. RESULTS: A total of 121 patients were enrolled. Baseline characteristics were comparable across the 2 groups. After treatment, the angina attack numbers in the HAA group were significantly reduced from 11.00 to 4.81 (P<0.05). While, for PAA group, the angina frequency was not significantly improved (baseline 10.55; post-treatment 11.05). The HAA group had significantly fewer angina attacks than the PAA group (P<0.05). Pain intensity measured by VAS in HAA group was significantly reduced from 4.06 to 3.02 (P<0.05). While, for PAA group, the VAS was significantly increased (baseline 3.62; post-treatment 3.96; P<0.05). Clinical outcomes showed better improvement after treatment in the HAA group than in the PAA group in terms of oral administration of rescue drugs, SAS, SDS and SAQ scores (P<0.05). The adverse events were also reported. CONCLUSION AP of GXSHP is a safe and effective treatment for CSAP patients (Registration No. NCT02029118).

This study investigated the molecular markers of DS-1-47, a component of an implantation- promoting traditional Chinese medicine consisting of Astragalus mongholicus, Atractylodes macrocephala, Scutellaria baicalensis and Dipsacales, in an attempt to clarify the molecular mechanism and action targets of DS-1-47. Controlled ovarian stimulation (COS) method was used to establish the implantation dysfunction models of mice. Animals were divided into normal pregnant group, COS model group and DS-1-47 group. Laser capture microdissection-double dimensional electrophoresis-mass spectrum (LCM-DE-MS) was used to analyze the uterine protein molecules that were possibly involved in the promotion of implantation. Twenty-three proteins in DS-1-47 group were significantly changed as compared to those in COS model group, with 7 proteins down-regulated and 16 proteins up-regulated. Except for some constituent proteins, the down-regulated proteins included collagen α-1 (VI) chain, keratin 7, keratin 14, myosin regulatory light chain 12B, myosin light polypeptide 9, heat shock protein β-7, and C-U-editing enzyme APOBEC-2; the up-regulated proteins included apolipoprotein A-I, calcium regulated protein-3, proliferating cell nuclear antigen, L-xylulose reductase, and calcium binding protein. These 23 proteins that were regulated by DS-1-47 represented a broad diversity of molecule functions. The down-regulated proteins were associated with stress and immune response, and those up-regulated proteins were related to proliferation. It was suggested that these proteins were important in regulating the uterine environment for the blastocyst implantation. By identification of DS-1-47 markers, proteomic analysis coupled with functional assays is demonstrated to be a promising approach to better understand the molecular mechanism of traditional Chinese medicine.

OBJECTIVEThe purposes of our study were to investigate the association between maternal urinary phthalate metabolites and the levels of inhibin B (INHB) and insulin-like factor 3 (INSL3) in the cord blood in a Chinese pregnant population.

METHODSMaternal urine samples in the third trimester of pregnancy of 69 participants were collected and stored, and the samples of cord blood (10 ml) were collected at delivery between June 2011 and September 2012 in a comprehensive hospital of gynecology and obstetrics in Tianjin, China.Four phthalate metabolites, monomethyl phthalate (MMP), monoethyl phthalate (MEP), monobutyl phthalate (MBP), and mono-2-ethylhexyl phthalate (MEHP) were measured in the urine samples using liquid chromatography-tandem mass spectrometry. The levels of INHB, INSL3 in the cord blood were tested by ELISA. Associations of phthalate exposure with INHB and INSL3 levels were determined by spearman correlation and multiple regression model analysis.

RESULTSThe median concentrations of observed metabolites in descending order were 49.74 µg/L for MMP, 24.96 µg/L for MEHP, 19.52 µg/L for MEP and 17.73 µg/L for MBP. The median concentrations of INHB and INSL3 were 89.09 and 106.21 ng/L.Significant negative associations between INHB and MMP(β' = -0.252), MEP(β' = -0.363) or the sum value (∑PAEs) (β' = -0.346) were found by the multiple regression model analysis. For INSL3, only the sum value (β' = -0.313) was inversely significantly associated with the levels of INSL3 in the cord blood.

CONCLUSIONSMaternal urinary phthalate metabolites were associated with INHB and INSL3 in the cord blood in a Chinese population.
