Objective To investigate mother-to-child transmission of HIV-1 and the factors that affect transmission. Methods 136 children who were born to HIV positive mothers in a high HIV prevalence region were interviewed and blood samples were examined for anti-HIV anti-HGV and HIV RNA or HIV DNA. Results Among 136 children who were born to HIV positive mothers, 50 were infected with HIV. The MTCT rate was 36.8% (50/136). Thirty eight DNA fragments of HIV-1 gag gene P17 obtained from HIV-1 seropositive mothers were amplified by PCR from uncultured peripheral blood mononuclear cells (PBMCs). Sequence analyses showed that all of them were HIV-1 B subtype. The HIV vertical transmission rate among mothers with AIDS (67.4%, 31/46) was significantly greater than among those with HIV alone (21.1%, 19/90), P

Objective To estimate the clinical features of hepatitis B virus (HBV) and hepatitis C virus (HCV) co-infection among acquired immune deficiency syndrome (AIDS) patients and the interaction of lamivudine (3TC) contained antiretroviral therapy (ART) with hepatitis virus replication.Methods From 2004 to 2010,199 human immunodeficiency virus (HIV)/HBV coinfected patients admitted to Zhongnan Hospital of Wuhan University were enrolled,including 76 cases of HIV/HBV/HCV triple infection and 123 cases of HIV/HBV dual infection.Hepatitis B surface antigen (HBsAg) and hepatitis B core antibody (anti-HBc) were detected routinely.HBV DNA,HCV RNA before and after ART with 3TC and incidence of end-stage-liver-diseases in two groups were compared.Categorical data were analyzed by chi-square test,and measurement data were compared by t test.Results Positive rates of HBV DNA in HIV/HBV and HIV/HBV/HCV coinfection group before treatment were 45.5 ％ (56/123) and 25.0 ％ (19/76),respectively (x2 =8.429,P=0.004).The levels of HBV DNA in the two groups before treatment were (5.61±1.88) lg copy/mL and (4.70±1.84) lg copy/mL,respectively (t=2.589,P=0.003).After ART with 3TC,detectable rate of HBV DNA in HIV/HBV/HCV group decreased to 9.2％ (7/76),which was significantly lower than pretreatment (x2 =6.681,P=0.010),but serum HCV RNA increased significantly from 56.6％ (43/76) pretreatment to 72.4％ (55/76) post-treatment (x2 =4.136,P=0.042).The incidence of end-stage-liver-diseases in HIV/HBV/HCV co-infected group was significantly lower than that of HIV/HBV dual infection group (18.8 per 1000 person years vs 42.1 per 1000 person years; x2 =4.459,P =0.035) during an average of 5.6 years of follow up.Conclusion It is possible that there are interactions between HBV and HCV when the two viruses are co infected.The timing of patient enrollment might be an impact factor on study results.

Forty-two patients with type 2 diabetes (DM group),23 type 2 diabetic patients with unstable angina pectoris (DM + UAP group),and 36 healthy subjects (control group) were enrolled in this study.Serum samples were collected for determining serum concentrations of vascular endothelial growth factor (VEGF),Angiopoietin (Ang)-1,Ang-2,angiogenin,angiostatin,basic fibroblast growth factor,and platelet-derived growth factor-BB using protein array technology.The results showed that there were no significant differences in serum concentrations of all 7 angiogenic factors between control group and DM group.Whereas,serum concentrations of V EGF and Ang-2 were significantly increased in DM + UAP group compared with control group [(3 532.10 ± 1 813.72vs 2 444.50 ± 1 152.21) pg/ml,(286.90-± 217.01 vs 171.92 ± 106.63) pg/ml,both P＜0.01].Pearson's correlation analysis revealed that serum concentrations of all 7 angiogenic factors were not related to HbA1C,fasting and 2 h postprandial plasma glucose,triglycerides,high density lipoprotein cholesterol,as well as low density lipoprotein cholesterol.

Objective To predict the pharmacological effect and targets of main chemical components of Lindera aggregata, and construct the multi-target network. Methods The potential targets and pathways of linderene acetate, isocembrol, laurolitsine, β-humulene, chamazulene, laurotetanine, and lindestrenolide, selected as the representative compounds of oils, alkaloids, and furan sesquiterpene lactones from Linderae Radix, were predicted by methods of network pharmacology. The pharmacodynamic effects of main chemical constituents of L. aggregata was analyzed by data integration. Results The in silico prediction results showed that seven compounds of L. aggregata affected 20 related pathways through 40 potential targets. The pathways were involved in several links including inflammatory, analgesic, gastrointestinal movement regulation, anti-oxidation, antitumor, liver injury protection, and immunoregulation. The various components showed common targets, pathways, and pharmacodynamic effects and had different emphases. Conclusion The pathways related to L. aggregata oils, alkaloids, and furan sesquiterpene lactones were connected by the common targets, showing the synergistic effect of different compounds by acting on multi-targets and multi-pathways. This study provides references for systematic exploration on the pharmacological actions and mechanisms of L. aggregata.

Objective To explore the clinical characteristics, pathological features and prognostic factors of patients with acquired immune deficiency syndrome (AIDS) related lymphoma (ARL).Methods The clinical characteristics, treatment regimen and survival status were retrospectively analyzed.At a ratio of 1∶2, 106 general non-Hodgkin lymphoma (NHL) cases were included after matching for demography and clinical characteristics with 53 ARL patients.Chi-square test was used for statistical analysis.Overall survival was analyzed using Kaplan-Meier curves.Cox regression was used for multivariant analysis.Results The predominant pathologic type of ARL was diffuse large B cell lymphoma (60.4%, 32/53).B cell lymphoma accounted for 88.7% (47/53) and T cell lymphoma accounted for 11.3% (6/53).Patients in ARL group (62.3%, 33/53) had lower proportion of receiving radiotherapy or chemotherapy compared with patients in general NHL group (94.3%, 100/106) (χ2=26.58, P<0.05).ARL group had lower hepatitis B surface antigen (HBsAg) positivity rate compared with general NHL group (1.9% vs 26.4%, χ2=14.26, P<0.05).No other characteristic was found significantly different between these two groups.The survival time of ARL and general NHL patients was (6.0±1.3) months and (48.0±10.0) months, respectively (t=8.13, P<0.01).The 1-year, 2-year, 3-year and 5-year survival rates of ARL patients were 39.6%, 32.7%, 27.7% and 20.1%, respectively, while those of general NHL patients were 79.2%, 56.8%, 42.4% and 25.0%, respectively.Of the 33 ARL patients and 100 general NHL patients who received anti-NHL treatment, the 1-year survival rates were 60.6% and 83.0%, respectively (χ2=4.040, P=0.043), the 2-year survival rates were 53.5% and 60.5%, respectively (χ2=0.003, P=0.096), the 3-year survival rates were 48.1% and 45.9%, respectively (χ2=0.288, P=0.59), the 5-year survival rates were 39.1% and 27.5%, respectively (χ2=0.798, P=0.372).Multivariate analysis revealed that anti-NHL therapy and international prognostic index score were independent predictors for prognosis (both P<0.05).Conclusions Diffuse large B cell lymphoma is the predominant pathologic type of ARL.ARL patients has significantly lower survival rate compared with general NHL patients.Combination of anti-HIV therapy and anti-lymphoma therapy in individuals with ARL can prolong their survival time.

Objective:To investigate the epidemic trend and risk change of acquired immunodeficiency syndrome (AIDS) complicated with malignant tumors after combination antiretroviral therapy (cART).Methods:The types of malignant tumors in patients with AIDS at different stages of cART were analyzed among anti-human immunodeficiency virus (HIV)-positive population in Hubei Province screened in National AIDS/HIV prevention and control information system from 1st January, 2004 to 31st December, 2018. The standardized incidence ratios(SIR) of malignant tumors in AIDS patients was analyzed based on the incidence of malignant tumors in the general population in Hubei Province or China in 2013. The changes in risks for development of malignant tumors in AIDS patients at different cART stages from 2004 to 2013 and 2014 to 2018 were compared.Chi-square test was used for statistical analysis.Results:Three hundred and twenty-three out of 22 994 AIDS patients were diagnosed with malignant tumors. Non-Hodgkin lymphoma(NHL) and cervical cancer were most common types in acquired immunodeficiency syndrome-defining cancers (ADC), while liver cancers and lung cancers were the most common types in non-acquired immunodeficiency syndrome-defining cancers (NADC). The overall risk of malignancy in AIDS patients was similar to that in the general population (SIR=1.06, χ2=0.62, P=0.426). However, the risks of Kaposi sarcoma, NHL, Hodgkin lymphoma, cervical cancer, and head and face cancers (excepting nasopharyngeal cancer) in AIDS patients were significantly higher than those in the general population (SIR=834.09, 9.65, 13.33, 5.22 and 2.94, respectively, χ2=11 747.27, 625.54, 56.65, 184.21 and 13.66, respectively, all P<0.01). The risks of lung cancer, colorectal anal cancer, stomach cancer and breast cancer in AIDS patients were significantly lower than those in the general population (SIR=0.33, 0.36, 0.43 and 0.45, respectively, χ2=33.43, 12.84, 9.01 and 7.21, respectively, all P<0.05). The SIR of cervical cancer, liver cancer and colorectal anal cancer from 2014 to 2018 were 4.06, 0.43 and 0.10, respectively, which were significantly lower than those from 2004 to 2013 (7.42, 1.96 and 0.84, respectively). The differences were all statistically significant ( χ2=5.39, 19.52 and 10.86, respectively, all P<0.05). Conclusions:At present, there are no significant differences of the incidences of malignant tumors between AIDS patients and general population, but the tumor types are different. The most common malignant tumors in this region are NHL and cervical cancer, which should be noted that HIV screening among patients with such tumors is conducive to comprehensive treatment to improve the efficacy.

ObjectiveTo explore the epidemiologic features and distribution pattems of hepatitis C virus (HCV) genotype infection among HIV positive former blood donors (FBDs) and transfusion recipients in Hubei province.Methods597 serum samples from HIV-positive patients in Hubei were collected and examined for anti-HCV by enzyme-linked immunosorbent assay ( ELISA ).Reverse transcription nested polymerase chain reaction (RT-nested PCR) amplification and DNA sequencing were used to evaluate the HCV core regions.ResultsThe prevalence rates of HCV in HIV positive FBDs and transfusion recipients were 76.5％ (205/268) and 57.4％ (189/329) respectively.HCV genotypes 1b (92.8％,90/97) and 2a (7.2％,7/97 ) were detected.ConclusionsBlood donation and blood transfusion are the major modes of HIV-HCV co-infection in Hubei province.The prevalence of HCV in HIV positive transfusion recipients is lower than that in HIV positive FBDs.HCV genotypes 1b and 2a are the predominant strains among HIV-positive FBDs and transfusion recipients.

Objective To analyze the incidence,mortality and risk factors of death in human immunodeficiency virus (HIV) and hepatitis C virus (HCV) co-infected patients with combined antiretroviral therapy (cART).Methods A total of 427 HIV/HCV co-infected patients admitted to Zhongnan Hospital of Wuhan University or local disease prevention and control canters from January 2003 to December 2010 were enrolled in the study.The demographic and clinical data of patients were retrospectively studied.Cox progressive regression model was used for data analysis,and Kaplan-Meier method was used to evaluate the effect of end-stage liver diseases on the death.Results of 427 HIV/HCV co-infected patients,53 ( 12.4％ ) died during the follow-up,in which 28 (52.8％) died of liver-related diseases.Male gender ( RR =2.63,P =0.05 ),infection via blood transfusion ( RR =2.15,P =0.04),baseline CD4 + T cells ＜50 cells/μL ( RR =2.83,P =0.02),HIV RNA≥ 104copies/mL at the end of follow-up (RR =2.79,P =0.00 ) and complicated with end-stage liver disease ( RR =7.79,P =0.00) were significantly related to the death.Duration of cART ＞ 5 years is a protective factor for the death ( RR =0.03,P =0.00).Themortality of patients complicated with end-stage liver diseases was 52.7％ ( 29/55 ).Conclusion Liver disease-related death has become the leading cause of death in HIV/HCV co-infected patients,and patients with end-stage liver diseases are of high risk of death.
