ABSTRACT
Objective@#To investigate the experience of child sexual abuse (CSA) and depressive symptoms among young men who sex with men (YMSM) in Guangzhou, and then to explore the impact of CSA on depressive symptoms.@*Methods@#A convenient sampling method was used to recruit MSM. YMSM who aged 18-24 and have lived in Guangzhou for more than 3 months were included in this study. Data on demographic characteristics, homosexual partners seeking behaviors, sexual orientation, CSA experience and depression were collected through an electronic questionnaire. χ 2 tests were used to compare the proportion of CSA and depressive symptoms among YMSM with different characteristics. Logistic regressions were preformed to assess the impact of CSA on depression.@*Results@#The proportion of CSA experience and depressive symptoms among participants were 31.51% (115/365) and 47.95% (175/365), respectively. Participants with junior high school education or lower and who sought homosexual partners offline reported(75.00%,62.22%) a higher proportion of depressive symptoms( χ 2=7.97，4.19， P <0.05). After adjusting for factors e.g. ethnicity, residence, resident duration in Guangzhou, studentship, education, monthly income, sexual orientation and homosexual partners seeking behaviors, the multivariable Logistic regression model showed that YMSM with CSA experience (a OR=1.81, 95%CI =1.12-2.93) were more likely to have depressive symptoms than those without CSA experience.@*Conclusion@#The prevalence of CSA experience and depressive symptom is relatively high among YMSM in Guangzhou, and CSA experience is associated with higher risk of depressive symptoms. More attention should be paid to strengthen the psychological intervention for YMSM, especially for those who experienced CSA, so as to reduce the risk of depression and improve mental health among YMSM.
ABSTRACT
The popularization of medical insurance in Panama has been basically completed. The coverage of health insurance is high, but with the problem of polarization. The major causes of death in Panama are is chemic heart disease, stroke, AD and diabetes. In recent years, the chronic kidney disease and COPD are increasing significantly. Panamanian native medicine, considered as complementary and alternative medicine, is recognized by local laws and usedby most of indigenous groups and rural people. Traditional Chinese Medicine (TCM) in Panama is at the starting stage, and there is no relevant legislation. However, this country attaches great importance to indigenous traditional medicine, and more and more people gradually accept it. TCM has great development potential in this country. It is suggested to promote the development of TCM in Panama. By culture as the pathway, exploring various forms of cooperation and exchange, taking the research and development of traditional herbal medicine as the breakthrough point, and increasing the spead of acupuncture usage, etc.
ABSTRACT
Objective@#To examine the prevalence and associated factors of seeking casual male sexual partners among men who have sex with men (MSM) students in Guangzhou, and to provide a reference for health education and intervention.@*Methods@#A cross-sectional study was conducted to recruit 189 MSM students aged 18 and 28 via voluntary counseling and testing (VCT) clinics, Lingnan partners and Zhitong charity from May 2017 to April 2018. An anonymous electronic questionnaire was administrated to collect information on sociodemographic and sexual behavior characteristics. Chi-square test and non-conditional Logistic regression analysis were performed to explore the associated factors of casual homosexual behavior among MSM students.@*Results@#In the past 6 months, 63.49% (120/189) of them reported casual male partners, and the rate of consistent condom use was 61.67%(74/120). Multivariate Logistic regression analysis showed that participants who had multiple sex partners in the past 6 months were more likely to seek male casual partners(aOR=9.13, 95%CI=4.27-19.53). Individuals who used recreational drugs before sex were at a higher risk of having casual sex behaviors(aOR=3.06, 95%CI=1.08-8.62). MSM students who had steady homosexual partners had a lower risk to seek casual sex(aOR=0.43, 95%CI=0.19-0.98).@*Conclusion@#The proportion of seeking casual male sexual partners among MSM students in Guangzhou was relatively high. The publicity and education should be strengthened among those who had multiple sex partners, with no steady homosexual partners and used recreational drugs before sex, to reduce the casual sex behaviors.
ABSTRACT
Objective@#To understand prevalence and determinants of prior HIV testing among male students who have sex with men (MSM) in Guangzhou,and to provide a reference for improving their HIV set.@*Methods@#Students who were MSM were recruited in Guangzhou from May 2017 to April 2018. Data on socio-demographic characteristics, sexual behavior, AIDS prevention service access and HIV testing history were collected. Multivariate non-conditional logistic regression was conducted to explore determinants with HIV testing.@*Results@#The median age of 223 students who were MSM was 22 years old (interquartile: 20-23). About 65.47% (146/223) of them had a history of HIV testing. Multivariate non-conditional logistic regression showed individuals who sought sexual partners online (OR=3.24, 95%CI=1.32-7.98), had anal sex in the last 6 months (OR=2.73, 95%CI=1.26-5.93), and had received AIDS prevention services(OR=2.87, 95%CI=1.51-5.34) were more likely to have a history of HIV testing. @*Conclusion@#Prior HIV testing among student MSM in Guangzhou was relatively low. Intervention should be tailored targeting student MSM who seek sexual partners offline, have only oral sex in the past 6 months, and receive no AIDS prevention services in the past year to expand the coverage of HIV testing.
ABSTRACT
Teaching model plays an important role in clinical education. Problem based learning (PBL) model, with an outstanding feature of stimulating the learning enthusiasm of students, was applied by many American colleges. American College of Acupuncture&Oriental Medicine (ACAOM) combined PBL teaching model with traditional lecture based learning (LBL) model, which had achieved good results. In this article, PBL model and its characters were explored via qualitative case analysis, to provide reference for universities and colleges of traditional Chinese medicine on clinical education.
ABSTRACT
Objective To investigate the reasons and the methods of prevention and cure for serious complications of radiofrequency ablations in the treatments of hepatocellular carcinomas. Methods A total of 410 patients with BCLC at A or B stage of hepatocellular carcinomas in our hospital were enrolled between November 2014 and June 2009. These patients underwent a total of 504 times radiofrequency ablations for the treatments of liver lesions. This retrospective study analysed the reasons and the strategies of prevention and cure for the serious complications. Results In the patients with a total of 504 times radiofrequency ablations, 2 patients had massive hemorrhage caused by puncture injuries, 2 patients had the tumors which were close to the liver capsules and 1 patient had bile peritonitis caused by the injury of thermal ablation on the gallbladder. The maximum diameter of tumor was 5 cm. That tumor was close to the gallbladder. 2 patients had needle tract metastases caused by incompletely needle path ablations. 1 of the 2 patients had a tumor near the liver capsule, and the other patient had un-enough temperature for needle path ablation. Tumor outbreaks were happened in 2 patients. 1 of the 2 patients had a tumor which was located in the liver capsule and close to the portal vein. The other patient had a 12 cm diameter tumor with rich blood supplement. 2 patients had liver abscesses. 1 of the 2 patients had a tumor near the ascending colon, and the other patient had diabetes. 1 patient had colonic perforation caused by thermal ablation. The tumor in that patient was located in the right hepatic lobe segment and adjacent to the ascending colon. The incidence of serious complications was 1.98% (10/504). Conclusions The incidence of the serious complications of radiofrequency ablations for the treatments of hepatocellular carcinomas is relatively low. The main reasons for the serious complications were direct injuries caused by punctures, heat radiation injuries, tumors adjacent to large blood vessels, gallbladders and intestines, tumors with abundant blood supplement, needle paths fail to cross normal liver tissues, low scores of liver function, weak immune system and diabetes. The key points for avoiding and reducing the serious complications are preoperative evaluations of patients' basic situations, choices of appropriate puncture channels and control ranges of ablations when tumors are close to important blood vessels, intestines and gallbladders.
ABSTRACT
Objective To investigate the antitumor effects of total glycoside of Cimicifuga dahurica (TGCD) in vivo and in vitro, and further explore its mechanisms. Methods The anti-tumor activity in vitro was determined by MTT assay and the anti-tumor activity in vivo was evaluated using experimental mouse tumor (S180) model and human tumor (A549) xenografts in nude mice. After treatment, A549 cell apoptosis and morphologic change were evaluated by Annexin V/PI flow cytometry and HE staining. Results Inhibitory concentration 50% (IC50) of TGCD on A549, HepG2, HL60, Eca-109 and MDA-MB231 cells were 20.3, 27.1, 21.2, 23.4 and 32.7 ?g/mL respectively. Administration of TGCD (100 or 200 mg/kg) inhibited S180 solid tumor development in mice, the inhibition rates were 42.8% and 54.6% respectively. Administration of TGCD (100 or 200 mg/kg) inhibited A549 tumor growth with a T/C (mean value of treated group/mean value of control group) value of 58.1% and 52.2% respectively. In addition, increased percentage of apoptotic cells induced by TGCD in human A549 nude mice xenografts and the histopathological changes including cell shrinkage and condensation of chromosomes were observed. Conclusion TGCD has demonstrated antitumor bioactivity both in vitro and in vivo, which may be related to its effects of inducing apoptosis activity.
