ABSTRACT
【Objective】 To analyze the association of overweight and obesity with elevated blood pressure(BP) among children and adolescents in Mengzi City, in order to provide reference for making effective interventions. 【Methods】 A total of 30 classes of students in 14 schools were selected into this study by a stratified random cluster sampling method from October 2020 to September 2021. The paticipants completed a questionnaire survey, and had their height, weight and BP measured. Logistic regression analysis was used to evaluate the association of overweight and obesity with elevated BP. 【Results】 A total of 4 015 children and adolescents aged 7 - 17 years were involved in the study. The detection rate of overweight, obesity and elevated BP was 12.53%, 10.01% and 12.38%, respectively. The detection rate of elevated BP was 9.96%, 19.48% and 25.62% in normal weight, overweight and obese groups, respectively. The risk of elevated BP in the overweight and obese groups was 2.190 times(95%CI: 1.696 - 2.926, P<0.001) and 3.243 times(95%CI: 2.501 - 4.204, P<0.001) as high as that in normal weight groups. The dietary and exercise behaviors of 1 604 adolescents were analyzed, it was found that the detection rate of obesity was significntly higher in non-boarding students(15.09%) and those who consumed fresh fruits at least once a day(13.49%)(χ2=18.012, 7.225, P<0.05), the detection rate of elevated BP was significantly higher in among those who did not consume sugary beverages(16.88%), and performed moderate-to-high intensity physical exercise of 60 minutes or more ≤ 2 days per week(16.88%)(χ2=9.403, 14.921,P<0.01). 【Conclusions】 The risk of developing hypertension increases with the high prevalence of overweight and obesity and is strongly associated with multiple factors. Therefore, it is essential to conduct effective weight control and behavioral lifestyle interventions among children and adolescents.
ABSTRACT
Objective@#To know condom use negotiation with clients and regular sex partners and condom use in female sex workers (FSWs), and provide reference for the development of comprehensive HIV/AIDS intervention for FSWs.@*Methods@#The cross sectional survey was conducted in Jianshui county and Mengzi county in Honghe Hani and Yi autonomous prefecture. A total of 476 FSWs aged 16 years and above were recruited from entertainment venues, and the information about their demographic characteristics, condom use negotiation and condom use were collected by using questionnaires. Logistic regression model was used to analyze related factors of condom use after negotiation between FSWs and clients unwilling use condom.@*Results@#A total of 852 FSWs who aged (24.29±8.44) years old participated in the survey. In past month, 499 FSWs had negotiation for condom use with unwilling clients (58.6%, 499/852), after negotiation, 441 FSWs (88.4%, 441/499) had consistent condom use in each sex with the clients. In the past one month, 99 FSWs had negotiation for unwilling use condom with regular sex partners (14.4%, 99/687), after negotiation, 54 FSWs (54.5%, 54/99) had consistent condom use in each sex with regular sex partners. Among the FSWs, 266 (53.3%, 266/499) reported that they could say "It is a mandatory requirement" to persuade clients who were unwilling to use condom. 97(19.4%, 97/499) reported that they could say "There is risk for infection" to persuade clients who were unwilling to use condoms. 115 (23.1%,115/499) reported that they could say "It is a mandatory requirement" and "there is risk for infection" to persuade their unwilling clients to use condoms. 21 (4.2%, 21/499) reported that they used other strategies. 22 (4.4%, 22/499) felt that it was difficult to persuade clients to use condoms. Multivariate logistic regression analysis showed that compared with FSWs who felt difficult in persuading clients to use condoms, FSWs who felt moderate difficulty were more likely to have consistent condom use after negotiation (OR=4.00, 95%CI: 1.55-10.32) and FSWs who felt easy in persuading clients to use condoms were also more likely to have consistent condom use (OR=30.17, 95%CI: 3.22-282.44). Compared with FSWs used other strategies to persuade their clients to use condoms, FSWs who said it was a mandatory requirement were more likely to have consistent condom use after negotiation (OR=4.44, 95%CI: 1.41-14.01) and FSWs who said it was a mandatory requirement and there was risk for infection were also more likely to have consistent condom use (OR=5.52, 95%CI: 1.55-19.73).@*Conclusions@#Negotiation for condom use increased the rate of condom use in FSWs in sex with clients who were unwilling to use condom. The negotiation strategy of "It is a mandatory requirement" would promote condom use in FSWs in sex with clients who were unwilling to use condom. Besides, the negotiation strategy of saying "there is risk for infection" had additional effects.
ABSTRACT
<p><b>OBJECTIVE</b>To understand the prevalence of high risk behaviors and influencing factors among HIV infected persons aged ≥50 years.</p><p><b>METHODS</b>Face to face questionnaire interview was conducted among the HIV infected persons selected in Jianshui, Gejiu and Mengzi counties in Yunnan province through random sampling in June 2015. The sample size was 450.</p><p><b>RESULTS</b>Among the HIV infected persons surveyed, 41.2% (122/296) had sexual behaviors with their spouses during past year, and the consistent condom use rate was 66.4% (81/122). Among the HIV infected males, 8.9% (28/313) had commercial sexual behaviors during past year, and the consistent condom use rate was 17.9% (5/28). Among the HIV infected females, 0.7% were still engaged in commercial sex service during past year. Among the 450 HIV infected persons, 32 (7.1%) reported having casual sex behaviors during past years, and the consistent condom use rate was 18.7% (6/32). The rate of commercial sexual behavior in urban residents (13.4%, 19/115) was higher than that in rural residents (4.5%, 9/198), the difference was statistically significant (χ(2)=11.715, P=0.001). The risk factors for commercial sex behaviors included lack of family and social support, aged 50-59 years, living in urban area, higher income and being male. The risk factors for using no condom included living in rural area, lower education level, lack of family and social support and higher income.</p><p><b>CONCLUSIONS</b>Risk sex behaviors are still prevalent in HIV infected people aged >50 years, which exacerbated HIV transmission. Further efforts should be focused on the education about AIDS prevention and control and promoting protected sexual behaviors. Additional effort should be done to improve the family and social support for HIV infected people aged >50 years. Moreover, comprehensive intervention for low-paid female sex workers also needs to be strengthened.</p>

Objective To evaluate the effect and safety of intravenous (IV) thrombolysis, intra-arterial (IA) thrombolysis and mechanical adjuvant intra- arterial thrombolysis (IA + MA) in treating cardiogenic cerebral embolism. Methods A total of 66 patients with cardiogenic cerebral embolism were randomly divided into IV group (n = 25), IA group (n = 18), IA + MA group (n = 23). The artery recanalization rate, NIHSS score, GCS score, BI excellent rate, symptomatic intracranial hemorrhage rate and mortality after different thrombolytic therapies were determined. The results were compared between each other among the three groups. Results In all three groups both the post-treatment NIHSS score and GCS score were significantly improved when compared with pre-treatment ones (P < 0.05). In IA + MA group the artery recanalization rate was 78.3%(18/23) and the BI excellent rate was 40%(10/25), which were significantly higher than those in IV group (P < 0.05). The symptomatic intracranial hemorrhage rate in IA group was 5.6%(1/18), which was strikingly lower than that in IV group (32%, 8/25). Analysis of the causes showed that the artery recanalization rate in patients with valvular heart disease or cardiac myxoma was rather lower, but the intracranial hemorrhage rate and mortality in these patients were much higher. Conclusion Thrombolytic therapy can improve neurological deficit in cardiogenic cerebral embolism, and the therapeutic effect of mechanical adjuvant intra- arterial thrombolysis is definitely better.
ABSTRACT
The maspin gene,a tumor suppressor gene and a member of the serpin superfamily,is isolated from mammary epithelial cells.Maspin gene plays an important role in the process of invasion and metastasis of gastric cancer.Researches show that maspin gene suppresses the occurrence,development and metastasis of gastric cancer mainly by inducing tumor cell apoptosis,inhibiting tumor angiogenesis,methylation modification,promoting homogeneity adhesion and inhibiting heterogeneous adhesion.
ABSTRACT
Objective To analyze basic data and outcomes in Chengdu Stroke Registry.Methods The stroke patients consecutively admitted to Department of Neurology,West China Hospital,Sichuan University since March 1,2002 were prospectively registered.The baseline demographic,risk factors,treatment,and outcome data was recorded with standardized stroke register form by trained specialists.The patients were followed up at seven days,one,three,six months and one year after onset of the stroke for death and disability.Results A total of 3123 consecutive patients were registered between March 1,2002 and August 31,2006,of which 65.5％ came from urban areas and 34.5％ from rural areas.The age was (63.05 ± 17.98) years old and male accounted for 60.3％.Ninety-seven percent (3028/3123) of patients completed CT or MRI scanning during hospitalization.A total of 1804 patients were included between March 2002 and September 2004,of which ischemic stroke accounted for 62.1％ (1120/1804),intracranial hemorrhage 28.4％ (513/1804),subarachnoid hemorrhage 4.0％ (72/1804) and TIA 5.5％ (99/1804).The median NIHSS score on admission was 8(3-15) points in patients with cerebral hemorrhage,and 5(2-10) points in patients with ischemic stroke.Compared with the patients with intracranial hemorrhage,patients with ischemic stroke more frequently had a history of diabetes (OR =2.427,95％ CI 1.811- 3.253,P=0.000),atrial fibrillation (OR=6.121,95％ CI3.535-10.60,P=0.000),coronary heart disease (OR=4.144,95％ CI 2.944-5.832,P =0.000) and TIA (OR=4.342,95％ CI 1.726-10.92,P =0.001 ),and less alcohol consumption ( OR =0.740,95％ CI 0.611-0.896,P =0.002 ).The proportion of in-hospital treatments were thrombolysis 0.9％,anti-platelet therapy 83.0％,mannitol 23.5％,neuroprotective agents (citicoline) 68.1％,and Chinese herbal medicine 89.7％.Case fatality rate was 10.7％ and 13.9％ respectively at 7 days and one month for patients with intracranial hemorrhage,3.0％ and 5.2％ respectively for ischemic stroke.Death or disability was 40.4％,40.3％ and 38.9％ in patients with intracranial hemorrhage and 37.1％,35.0％ and 33.4％ for ischemic stroke at the end of 3,6,12 months respectively.Conclusions Our stroke registry is featured with the largest sample,and the longest period of consecutively registration.It provides an important platform for clinical investigation of stroke.Our study suggested case fatality and disability is lower in this group than in other ethics.Above features should be considered in design of future clinical trials in China.
