HIV/AIDS has posed an increasingly serious issue in China. In recent years, Chinese government has taken further intensified efforts to combat HIV/AIDS with high-level political commitment, supportive policy development, increased financial allocation, large-scale of governmentled initiatives, expanded international cooperation and great involvement of non-governmental organizations. Meanwhile gaps and challenges coexist impacting the implementation and the results of national HIV/AIDS programs. Thus, further government efforts are needed to improve and tailor the actions to meet the requirement of HIV/AIDS control in China.

Objective: To analyze the mental health status of the Chinese Medical Team (CMT) members and its influencing factors. Methods: A total of 1 015 members of the CMT were recruited and surveyed by using a self-administered questionnaire and 12-item General Health Questionnaire (GHQ-12) from May 10 to June 10, 2018. Multivariable logistic regression models were used to identify risk factors for mental health problems. Results: A total of 808 subjects completed the questionnaire and an estimated 25.9% of them were suspected to have mental health problems (GHQ-12≥3). Logistic model analysis indicated that family life (OR=1.928, 95%CI: 1.162-3.197), domestic work status (OR=2.069, 95%CI: 1.210-3.538), father’s health status (OR=1.703, 95%CI: 1.060-2.736), disease symptoms (OR=2.087, 95%CI: 1.363-3.194), captain (OR=1.996, 95%CI: 1.128-3.532), cultural differences (OR=2.439, 95%CI: 1.621-3.671) were the risk factors for mental health. Age (OR=0.736, 95%CI: 0.571-0.949), leisure activities (OR=0.654, 95%CI: 0.490-0.872) were the protective factors. Drinking habits (OR=7.439, 95%CI: 1.290- 42.900), loneliness (OR=4.094, 95%CI: 2.438-6.875), and respect from the hospital (OR=0.783, 95%CI: 0.610-1.004) were relative to mental health problems. Conclusion CMT members have certain mental health problems, especially young members and captains. Therefore, interventions should be implemented to improve the mental health of CMT members and to promote the development of foreign aid work.

Objective To investigate the current situation of clinical nurses′ rights & interests maintenance and occupational stress in Hengyang, and explore the relationship between nurses′rights&interests maintenance and occupational stress.Methods Totally 690 nurses from ten secondary and tertiary hospitals in Hengyang were surveyed during August and September 2015 by general information questionnaires, nurses′rights & interests maintenance questionnaire and nurses occupational stress scale.Results The scores of nurses′rights & interests maintenance and nurses′occupational stress were (3.47±0.67), (3.21±0.95). The score and dimension scores of nurses′rights&interests maintenance were negative correlated with the total score and factor scores of nurses′occupational stress (r=-0.263- -0.425,P< 0.01). Job stress, one child or not, age, role adaptation, monthly income were indicated as predictive factors of rights & interests maintenance of nurses. Conclusions Rights & interests maintenance and occupational stress of nurses has a significant correlation, therefore, the medical and health institutions should further implement relevant laws and regulations; protect rights and interests of nurses from different aspects to reduce occupational stress;and stabilize the nursing team and promote development of nursing career.

Objective To explore the efficacy and safety of HAA regimen (homoharringtonine,cytarabine and aclarubicin) in the treatment of 150 newly diagnosed adult acute myeloid leukemia (AML).Methods All patients entered the study from May 1999 to June 2008 were treated with HAA regimen. Coxsurvival analysis was used to estimate the survival rate and differences between M1/M2 and M4/M5 were compared with 2-sided log-rank test. Results Out of the 150 patients, 121 (81%) achieved complete remission (CR). After the first course, CR rate was 68%. The CR rates of 97%, 84% and 38% were achieved in patients with favorable, intermediate and unfavorable cytogenetics, respectively. For the patients with CR, the median follow-up time was 16.5 ( 1.5-100.5 ) months, and the estimated 3-year survival rate was 45%. The estimated 3-year relapse free survival rate was 52% for the 121 patients with CR.Conclusions HAA regimen may be an efficacious and safe regimen with a good toleration in the induction therapy for newly diagnosed AML, and a high CR rate could be achieved with only one or two courses.

Objective To explore the relationship between ATP content in CD4+ T lymphocytes and acute rejection after liver transplantation(LT). Methods This study contained 77 patients who received LT from February to October 2009, They were divided into AR (acute rejection) and NAR (non-acute rejection) groups while 56 healthy people were enrolled to serve as the control group.Blood specimens were collected preoperatively and at 1, 2 and 4 weeks postoperatively. For the AR group, specimens were also collected on the day when AR occurred and 1 week after steroid bump together with that of the healthy people. ImmuKnowTM test kits for immune cell function were used to assay the ATP value. Results ATP values within CD4+T lymphocytes were elevated significantly in each group compared with those preoperatively. Peak level was reached in the AR group and was significantly higher than that of the contemporary NAR group (P＜0.05). ROC curve analysis showed that the obvious elevation of the ATP value within CD4+ T lymphocytes 1 week postoperatively had better sensitivity and specificity in diagnosing AR. The ATP sensitivity rate for early AR was 84.6 %and specificity rate 81 %. The ATP value within CD4+ T lymphocytes on the day of AR occurrence had a positive relationship with the rejection acting index(RAI), while relative index (r) was 0. 876(P＜0.05). After the steroid dump treatment, AR in all the patients was reversed and the ATP value declined significantly as compared with the control group and the day when AR occurred(P＜0. 05).Conclusion During the postoperative period, the dynamic change of ATP value within CD4 + T lymphocyte had a close relationship with acute rejection after liver transplantation. Thus, it might be used as a feasible and noninvasive monitoring index for diagnosing AR and the effectiveness of the anti-rejection treatment.

Objective To understand the prevalence and the factors associated with depression and anxiety among patients attending the community-based methadone maintenance treatment(MMT) program.Methods 9 MMT clinics in 3 provinces were randomly selected,in which 1 301 MMT patients who met the criteria of recruitment were all interviewed.A cross-sectional study by administrative questionnaire was employed to investigate the demographics,drug abuse and MMT treatment status of the respondents.The 1301 respondents were also evaluated for depression and anxiety by SDS(Self-Rating Depression Scale) and SAS(Self-Rating Anxiety Scale) respectively.ANOVA and multivariate linear regressions analysis was used to verify the factors associated with depression and anxiety respectively.Results The prevalence of depression and anxiety among the MMT patients were 38.3%(498/1 301) and 18.4%(239/1 301).The multivariates linear regression analysis indicated that at the level of ?=0.05,gender,employment status were associated with depression,while gender,employnment status,educational level,drug abuse and methadone daily dosage were associated with anxiety.Conclusions There are certain proportions of MMT clients who suffer from depression and anxiety.The MMT clinic staff should put more emphasis on the efforts to reduce psychological disorders and its potential risks by enhancing psychological councelling,intervention and social support towards the MMT patients.

Objective To investigate the effect of U50488H on the ultrastructure and organ function in septic shock rats. Methods Forty SD male rats were randomly(random number) divided into 5 groups: sham group, septic shock group, U50488H+septic shock group, nor-BNI+U50488H+septic shock group, and nor-BNI+septic shock group, with 8 rats in each group. Cecal ligation and puncture (CLP) was performed to induce septic shock in the septic shock group. Rats in the U50488H+septic shock group were treated with U50488H injection by intravenous at the shock point, and other procedures were the same as the septic shock group. Rats in the nor-BNI+U50488H+septic shock group were treated with nor-BNI injection by intravenous 3.5 h after abdomen closed, and other procedures were the same as the U50488H+septic shock group. Except for U50488H injection, rats in the nor-BNI+septic shock group received procedures the same as the nor-BNI+U50488H+septic shock group. Albumin, cardiac troponin I (cTnI) and N terminal pro B type natriuretic peptide (NT-proBNP) in serum were measured at abdomen-closed, 3, 6, and 12 h after CLP. The changes of histology and ultramicro structure under electron microscope of lung, heart, liver and kidney of rats were observed at 12 h after CLP. Statistical analysis was performed using SPSS 19.0. Comparison among groups was carried out using ANOVA, and Student's t-test was used for multiple comparisons as post-hoc. Results At 6 and 12 h of CLP, serum albumin of the septic shock group were significantly lower than those of the sham group (P<0.01), while those in the cTnI and NT-pro BNP groups were higher at 3, 6, and 12 h of CLP (P<0.01). Compared with the septic shock group, serum albumin of the U50488H+septic shock group increased significantly (P<0.01), whereas the serum levels of cTnI and NT-pro BNP decreased remarkably at 3, 6 and 12 h of CLP (P < 0.05, P < 0.01, respectively). Compared with the sham group, the alveolar wall was severely damaged, the alveolar septum and blood vessel wall were thickened obviously; the myocardial fiber was swollen, necrotic, and the infiltration of central granulocyte was increased significantly; hepatocyte showed edema, vacuolar-like steatosis, fatty degeneration, spotty and focal necrosis; and slight edema and vacuolar degeneration were found in the glomerulus endothelial in the septic shock group. Compared with the septic shock group, the ultrastructural damage of the lung, heart, liver and kidney of the U50488H+ septic shock group was significantly improved. All the above effects of U50488H could be blocked by nor-BNI (a selective κ-opioid receptor antagonist) (P<0.01). Conclusions U50488H can promote the recovery of serum albumin, and protect organ function in septic shock rats.

Objective To evaluate the relationship between the changes in gray matter volume ( GMV) in different brain regions in the early postoperative period and the development of chronic pain after radical mastectomy. Methods Forty-four American Society of Anesthesiologists physical status Ⅰ or Ⅱpatients, aged 25-64 yr, scheduled for elective radical mastectomy, were divided into 3 groups according to the numeric rating scale ( NRS) score within 3 months after surgery: severe chronic pain group ( NRS score≥3, group SEP), slight chronic pain group (NRS score=1 or 2, group SLP) and no chronic pain group ( NRS score=0, group NP ) . All the patients underwent whole brain MRI scan within 7 days after surgery. MRI data processing and analysis were carried out using SPM8-based VBM software package and REST 1. 8 software. Results There were 17 cases in group SEP, 10 cases in group SLP and 17 cases in group NP. Compared with group NP, GMV in the right postcentral gyrus was significantly decreased, and GMV in the right superior frontal gyrus was increased in group SEP ( P＜0. 01) . Conclusion The changes in GMV in the right postcentral and superior frontal gyrus in the early postoperative period may be related to the development of chronic pain after radical mastectomy.

Objective: To analyze the characteristics of high risk sexual behaviors and HIV infectious status among men who have sex with men (MSM) who use drugs in Tianjin in 2016. Methods: From April to December in 2016, MSM who use drugs in Tianjin were targetedly and extensively mobilized to receive testing by snowball sampling method. The inclusion criteria were as follows: men aged 18 years old and above; have had oral or anal sex with men in the last 6 months; have had drug abuse history in the last 6 months, including the use of rush poppers, 5-Methoxy-diisopropyltryptamine (5-MeO-DiPT), and Methamphetamine Synthesis substances; and with no mental disorder or mental deficiency. In this study, 302 MSMs were recruited to collect information of social demographic characteristics, drug abuse situation, sexual behavior after drug use, HIV test and the infectious status was collected through the online questionnaire, and the descriptive analysis was conducted. Results: From January to December 2016, a total of 302 subjects were recruited, among whom 194 (64.2%) aged 21-30 years old, 223 (73.8%) were unmarried and 28 (9.3%) were students. In the past 6 months, 297 (98.3%) used rush poppers, 31 (10.3%) used 5-MeO-DiPT, and 14(4.6%) used Methamphetamine Synthesis substances. The proportion of having sex after using the three types of drugs were 87.9% (n=261), 83.9% (n=26) and 92.9% (n=13), 85.5% (n=254), 87.1% (n=27) and 92.9% (n=13) of the subjects reported the sexual pleasure and sexual desire increased after using drugs, respectively. After using the three types of the drugs,58.6% (n=174), 83.9% (n=26) and 92.9% (n=13) of the subjects reported the duration of each sexual activity prolonged. In the past 3 months,48.3% (n=146) had stable sexual partners, 72.5% (n=219) had temporary sexual partners and 12.3% (n=37) had group sexual behaviors. 41 out of 302 subjects were HIV positive with the HIV positive rate at 13.6%. Conclusion Most of the MSM who use drugs were young, and always had sex when they use drugs. There is a relatively high HIV prevalence in this population.
