Purpose:To study the efficiency and safety on vinorelbine combined with capecitabine in the treatment of metastatic breast cancer. Methods:Twenty-eight patients with measurable lesions of metestetic breast cancer received vinorelbine 6 mg/m 2 d 1-5 civ,cycles were repeated every 21 days. Patients received capecitabine for 2-4 cycles at the same time. All patients received more than one course of chemotherapy regimens and 19 patients had adriamycin and (or) paclitaxel treatment. Results:Thirteen patients received two cycles treatment and fifteen patients received four cycles of treatment. Complete response in one patient,partial response in six patients,minor response in seven patients,stable response in seven patients and progressive disease in seven patients were observed. Overall responsed rate was 50%.The common side effects were neutronpenia,hand-foot syndrome,skin pigmentation,fatigue. Conclusions:The combination of vinorelbine and capecitabine in the treatment of metastatic breast cancer was effective and the toxicities were tolerable. It is possible that this regimen is an ideal second line chemotherapy for metastatic breast cancer.

Objective To explore the influencing factors of late diagnosis for newly diagnosed HIV/AIDS positive patients in Guangxi in 2015.Methods The CD4 + T lymphocytes count which was first detection for newly diagnosed HIV/AIDS positive patients in Guangxi during 2015 was collected.Data were statistically analyzed.Results We collected 8 586 newly diagnosed HIV/AIDS whose median CD4+ T lymphocytes counts was 237.5 cells/μl,and 43.12％ of them had less than 200 cells/μl.Gender,age,occupation,marriage,nation,education,route of transmission,types of testing and region had effects on late HIV diagnosis(all P ＜ 0.05).Logistic analysis found that risk factors associated with the late diagnosis of HIV were male(OR =1.851,95％ CI:1.673-2.048),migrant worker (OR =1.387,95％ CI:1.242-1.549),education below middle and secondary school(OR =1.619,95％ CI:1.400-1.873),currently married(OR =1.207,95％ CI:1.075-1.354),divorced or widowed(OR =1.508,95％ CI:1.309-1.738).Voluntary testing was a protective factor.Conclusions The prevalence the late diagnosis of HIV was high in Guangxi in 2015,it is crucial for related departments to enhance the testing and screening effort for HIV/AIDS.

OBJECTIVETo study on the chemical constituents of Lobelia chinensis.

METHODThe coloumn chromatographic techniques were applied to isolate constituents, and their structures were elucidated by means of spectral data analysis.

RESULTSixteen compounds were isolated and identified as daucosterol (1), diosmetin (2), apigenin (3), chrysoeriol (4), loteolin (5), hesperidin (6), loteolin-7-O-beta-D-glucoside (7), apigenin-7-O-beta-D-glucoside (8), linarin (9), diosmin(10), 5,7-dimethoxy-8- hydroxycoumarin (11), palmitinic acid (12), lacceroic acid (13), stearic acid (14), beta-sitosterol (15), daucosterol (16).

CONCLUSIONAll of these compouds were obtained from L. chinensis for the first time.

Objective: To observe the changes of Notch signaling pathway related molecule expression in hippocampus of rats with stagnation of liver qi and spleen deficiency syndrome and to explore the regulatory effect of Xiaoyaosan. Methods: Male SD rats were randomly divided into four groups: normal group, model group, model+xiayaosan group and model+fluoxetine group, each group had 12 rats. The stagnation of liver qi and spleen deficiency model was established by chronic immobilization stress for 21 days. Detection of Nissl bodies by Nissl staining, expression of NICD, Hes1, Hes5 and Jad1 were detected by Fluorescent quantitative PCR and Western-blot method. Results: Compared with the normal group, the number of Nissl bodies in the model group decreased significantly (P ＜ 0.01), which showed that Xiaoyaosan and fluoxetine could reverse it (P ＜ 0.01). The expression of Notch signaling pathway-related protein in model group was significantly lower than that in normal group (P ＜ 0.01), which showed that Xiaoyaosan and fluoxetine could reverse the expression of NICD, Hes5 and Jag1 protein (P ＜ 0.05, P ＜ 0.01). Compared with the normal group, the expression of each gene in the model group decreased (P ＜ 0.01), which showed that Xiaoyaosan and fluoxetine could reverse the expression of NICD, Hes1 and Hes5 mRNA (P ＜ 0.05, P ＜ 0.01). Conclusion: The hippocampal neurons of rats with stagnation of liver qi and spleen deficiency syndrome were damaged and the Nissl bodies were reduced, the expression of each protein and gene in Notch signaling pathway decreased. Xiaoyaosan may play a therapeutic role by regulating the expression level of hippocampal related molecules to protect neurons.

Objective To understand dynamic variation of CD4-Positive T-Lymphocytes counts and influencing factors among patients receiving highly active anti-retroviral therapy (HAART) in Guangxi.Methods Adult patients who received antiviral treatment for the first time after 1 January 2013 were selected.Their CD4-Positive T-Lymphocytes counts at baseline,6 months and 12 months after treatment were analyzed.By using the general linear model repeated measures ANOVA,CD4-Positive T-Lymphocytes dynamic variations and influencing factors were described and analyzed.Results The average CD4 cell counts of 4 082 patients at baseline,6th months and 12th months were (195.3 ± 155.7) cells/mm3,(331.9 ± 202.6) cells/mm3 and (380.9 ± 221.3) cells/mm3,respectively.The time specific differences in CD4-Positive T-Lymphocytes count among them were statistically significant (F=3 161.124,P=0.000).CD4-Positive T-Lymphocytes counts increased over time after treatment.The main influencing factors were sex,age,baseline CD4 cell count,medication,discontinuation of treatment or dose miss.Influenced by sex,age,medication,discontinuation of treatment or dose miss,the increased CD4-Positive T-Lymphocytes count showed a linear trend.Influenced by baseline CD4-Positive T-Lymphocytes counts and dose miss,the increase of CD4-Positive T-Lymphocytes count showed a trend which was conformed to quadratic curvilinear equation.Conclusion CD4-Positive T-Lymphocytes counts among patients receiving HAART in Guangxi were influenced by many factors.It is necessary to select the time to start treatment according to patient' s characteristics to get good outcome.

OBJECTIVETo understand the efficacy of antiviral therapy on prevention of HIV transmission and to assess the feasibility of treatment-as-prevention strategy in public health practice, among sero-discordant couples in Guangxi Zhuang autonomous region (Guangxi).

METHODSData was gathered through the AIDS prevention and control information system in Guangxi from January 1, 2008 to December 31, 2014, on HIV sero-discordant couples. Time-dependent Cox Model was used to analyze the efficacy of antiviral treatment.

RESULTSA total of 7 694 sero-discordant couples were followed and 394 appeared positive from those negative spouses. The overall HIV positive seroconversion rate was 2.5 (2.2-2.7) /100 person-year. The HIV positive sero-conversion rates were 4.3 (3.7-4.8) /100 person-year in the untreated cohort and 1.6 (1.4-1.9) per 100 person-year in the treated cohort. Rate of HIV transmission declined by 51% in the treated cohort (HR=0.49, 95%CI: 0.40-0.60) but appeared as 45% (AHR=0.55, 95%CI:0.43-0.69) after adjusting for factors as sex, age, education, marital status, occupation, transmission route and baseline CD4(+)T lymphocyte cell count. The rate of reduction in transmission was significant among couples in which the HIV-positive spouses showing the following features as: aged ≥25 years, married, farmers, with educational level of junior high school or below, baseline CD4(+)T lymphocyte cell count <500 cells/mm(3) and infection was through heterosexual intercourse.

CONCLUSIONAntiviral therapy as a prevention strategy among sero-discordant couples seemed feasible and effective in Guangxi. Expansion of the coverage on antiviral therapy would reduce the spread of HIV in married couples.
