Objective::To evaluate the early pregnancy loss (EPL) rates in women with and without low molecular weight heparin (LMWH) treatment during early pregnancy.Methods::A retrospective, non-randomized study was conducted at Guangzhou Women and Children’s Medical Center between June 2019 and March 2022, involving women diagnosed with polycystic ovary syndrome (PCOS). All participants conceived following standard preconception care and voluntarily chose either the control group or the LMWH intervention group during the first month of pregnancy. The intervention was administered throughout the entire first trimester. Early and final pregnancy outcomes were recorded, with a particular focus on EPL rates. In addition, venous blood samples and clinical data were collected to compare hormonal profiles, blood lipid levels, and anthropometric parameters between the two groups. Statistical analyses included the two-tailed unpaired Student’s t-test, Mann–Whitney U test, Chi-square test, and Kaplan–Meier survival analysis. A value of P < 0.050 was considered statistically significant. Results::Thirty-eight women in the LMWH group and 102 women in the control group were included. The EPL rates in the LMWH and control groups were 5.3% (2/38) and 26.5% (27/102), respectively ( χ2 = 7.582, P = 0.006, odds ratio ( OR) = 0.154, 95% confidence interval ( CI): 0.035-0.685). The age ( P = 0.005), PCOS subtype ( P = 0.012), and levels of total cholesterol ( P = 0.003), and high-density lipoprotein ( P = 0.018) were significantly different between these two groups. Continued follow-up was performed to observe the long-time effects of LMWH treatment in early pregnancy. Seventy-three patients were successfully delivered, 23 patients in the LMWH group and 50 patients in the control group. There was no significant difference between the LMWH and control groups in gestation length, bleeding during delivery, birth weight, gender of the newborn, or mode of delivery. In addition, Kaplan-Meier curve analysis revealed that LMWH treatment may decrease the risk of EPL in PCOS patients in the first trimester ( χ2 = 4.144, P = 0.040). Conclusion::LMWH treatment during early pregnancy may reduce the EPL rate in women with PCOS.

Objective: To discuss the prevalence and influential factors of stroke among population in Jiangxi Province. Methods: Four cities in urban areas and four counties in rural areas were selected firstly, in which two districts or townships were selected; and then three communities or villages were chosen from each district and township, respectively, using the simple random sampling (SRS) method. Finally 15 269 subjects aging 15 years old or above, living in Jiangxi Province ≥6 months were randomly selected to participate in this survey from November 2013 to August 2014. Information of population characteristics, life behavior way, individual disease history were collected through questionnaire survey, and height, weight, waist circumference, blood pressure, body fat rate, visceral fat index and so on were measured by instruments. Risk factors of stroke prevalence were analyzed by the unconditioned logistic regression analysis. Results: A total of 15 269 participants (6 267 males) from 15 364 eligible participants were included in the statistical analysis. Out of which, 7 793 participants came from urban areas, and their average age was (53.04±17.91) years old. In this study, 226 stroke patients (117 males) were found among15 269 participants, including 122 urban participants and 104 rural participants, whose average age was (67.76±9.74) years old. The prevalence of stroke was 1 480.12/100 000 in 2014, which was separately 1 866.92/100 000 and 1 210.84/100 000 among males and females. The prevalence of people aging (45-49) years old was 413.79/100 000 (6/1 450) , while which among people aging 75 years old and above was 3 311.62/100 000 (61/1 842) . The prevalence of stroke among residents in Jiangxi presented an uprising tendency with age increasing (linear-by-linear association χ²=62.23, P<0.01). The research showed that when other influencing factors including gender, BMI, waist circumference, pulse-pressure difference, VAI, and sleeping time in non-working days were controlled, hypertensive patients had a higher risk of stroke than people without hypertension (OR=6.88, 95%CI: 4.90-9.67), drinkers had a higher risk of stroke than non-drinkers (OR=1.56, 95%CI: 1.17-2.08), compared with people <65 years old, people aged 65-74 years old and ≥75 years old had a higher risk of stroke, the value of OR (95%CI) were 1.88 (1.36-2.59) and 1.97 (1.39-2.80), respectively, compared with people with normal body fat percentage, people whose body fat percentage on high side and people who with high body fat percentage had a higher risk of stroke, the value of OR (95%CI) were 1.71 (1.18-2.48) and 1.74 (1.18-2.56), respectively, people with sleep time >8 h had a higher risk of stroke than those with sleep time of 6-8 h. Conclusion There was a high stroke prevalence among residents in Jiangxi province. Hypertension, drinking, age, BFP and sleep duration were associated with stroke prevalence. Corresponding measures for high-risk population and risk factors should be strengthened to prevent and control the stroke.

Objective:To investigate the relationship between FA,ET-1,Hcy and VEGF in patients with pregnancy induced hypertension.Methods:Selected 80 cases of patients with pregnancy induced hypertension who were treated in our hospital from January 2013 to September 2016,divided into A group (40 cases),and preeclampsia and preeclampsia B group (40 cases),60 cases of normal late pregnant women as C group,60 cases of normal non pregnant women as D group.The plasma levels of FA,ET-1,Hcy and VEGF in each group were detected,and the correlation analysis was performed.Results:The plasma levels of FA and VEGF of group B were lowest in the four groups (P＜0.05),the plasma ET-1 and Hcy levels of group B were highest (P＜0.05).The plasma FA and VEGF levels of women with pregnancy induce hypertension were lower than those of the healthy late pregnant women.The plasma ET-1 and Hcy levels were higher (P＜0.05).The multivariate logistic regression analysis showed that FA,ET-1,Hcy and VEGF levels were risk factors for pregnancy induce hypertension.Conclusion:The elevation of plasma Hcy level caused by FA deficiency in pregnancy might be related to the development of the disease and the incidence of pregnancy induced hypertension syndrome,VEGF might be an important factor in the occurrence and development of pregnancy induced hypertension syndrome.
