Objective To analyze the data of TB/HIV dual infection screening and treatment monitoring in Guangxi during 2010-2015 and to evaluate the prevention and treatment status quo and development trend.Methods The annual monitoring report forms of TB/HIV dual infection during 2010-2015 were collected for deriving the special data of AIDS in corresponding years.Then the data were conducted the comparison and trend analysis.Results The acceptance rates of HIV detection among Guangxi TB patients and the acceptance rate of TB related screening detection in patients with HIV infection/AIDS showed the increasing trend year by year (P＜0.05);the positive detection rate of two-way showed the decreasing trend year by year (P＜0.05).The patients with TB/HIV dual infection were mainly concentrated in the central area of Guangxi.The annual monitoring report table data in annual monitoring TB/HIV dual infection prevention and treatment work trended to be consistent with the twoway registration and screening data in the special report system,but the errors still existed;the rate of receiving anti-TB and anti-viral combined therapy in the patients with TB/HIV dual infection was lower,which was fluctuated from 20％ to 60％;the treatment success rate was still elevated year by year,but which was affected by death,lose and other outcomes.Conclusion The TB/HIV dual epidemic situation has already obtained a certain effect along with comprehensively promoting the dual infection prevention and control work in Guangxi area.

Objective To study the spatial and temporal mode of infectious TB transmission in Guangxi Zhuang Autonomous Region (Guangxi).Methods Data related to infectious TB case (Include smear and/or culture positive patients) in Guangxi were collected from the National Notifiable Disease Reported System (NNDRS) from 2010 to 2015.Spatial-temporal analysis and prediction were performed by SaTScan 7.0.2,GeoDa 1.8.12,R program v 3.3.1 and SPSS 19.0 software,using the time series model,Moran' s I global and local spatial autocorrelation (Empirical Bayes adjustment).Kulldorff ' s space-time scan statistics displayed by R software was used to identify the temporal and spatial trend of TB.Results The total number of infectious TB cases,collected from NNDRS was 76 151,and showing a decreasing trend on annual incidence (value of Chi-square for Linear trend=3 464.53,P-value=0.000).The forecast value of TB cases in 2016 was 7 764 (4 971-10 557),with peak in March,analyzed through the Winters' multiplicative model.The Moran' s I global Statistics was greater than 0 (0.257-0.390).TB cluster seemed to have been existed for several years.The most significant hot spots seemed to be mainly located in the central and western parts of Guangxi,shown by local spatial autocorrelation statistics and the result from space-time scanning.Counties or districts that located in the east parts of Guangxi presented the low-low relation (significant cold spots).The situation of infectious TB seemed migratory.Conclusions Our data showed an annual decreasing trend of incidence on infectious TB with temporal concentration in spring and summer.Main clusters (hot spots) were found to be located in the central and western parts of Guangxi.Hopefully,our findings can provide clues to uncover the real mode of TB transmission at the molecular-biological level.

Objective To study the features of liver damage caused by anti-TB medicines among patients with TB-HBV co-infection, in order to complement and improve the implementation of DOTs strategy in the region. Methods A historical cohort study was conducted including the process of reviewing and analyzing files of the 781 naive TB patients hospitalized from June 2004 to October 2005. Cases were divided into HBsAg (+) group and HBsAg (-) group. Results The overall damage rate among the 781 investigation cases was 20.74%, including 121 cases (74.69%) in HBsAg (+) group and 41 cases (25.31%) in HBsAg (-) group. Data showed that liver damage rate and average value of ALT and AST of HBsAg (+) group were higher than those in HBsAg (-) group. First case with liver damage in HBsAg (+) group happened on the 7th day of the treatment, while the first liver damage case happened in HBsAg (-) group was on the 16th day. The average onset in HBsAg (+) group was earlier than HBsAg (-) group for 18.09 days. The average time of liver function recovery in HBsAg (+) group was 57.02 days and in HBsAg (-) group it was 27.56 days while the appearance among HBsAg (+) group was 29.46 days later than in HBsAg (-) group. Conclusion The incidence rate of liver damage caused by anti-TB medicines was higher among HBV positive patients than those HBV negative patients. Patients co-infected with HBV infection appeared to be more serious, with higher incidence on liver damage and earlier onset, as well as with the degree of damage to the liver.

Objective: To evaluate the expression of histone H4 acetylation(Ac-H4) during the cleft palates formation induced by 2, 3, 7, 8-tetrachlorodibenzo-p-dioxin(TCDD) in C57BL/6J mice. Methods: Forty-eight pregnant C57BL/6J mice were completely randomly divided into two groups: ① TCDD group, mice were treated with 20ug/kg of TCDD on gestation day (GD) 10.5 by gastric perfusion; ② control group, mice were treated with an equivalent of corn oil. The head samples were collected and sliced in coronal plane on GD13.5, GD14.5 and GD15.5 respectively. Histone H4 acetylation in the palates were evaluated by immunohistochemical staining and Western Blot in the two groups. Results: Histone H4 acetylation was mainly expressed in the palatal epithelial cells and slightly expressed in mesenchymal cells. The expression level of histone H4 acetylation was 0.6002±0.2530, 0.9180±0.0941 and 0.8966±0.0908 respectively in control group on GD13.5, GD14.5 and GD15.5; while 1.0229±0.2779, 1.6095±0.2651 and 1.2758±0.1251 in TCDD group. There were statistically significant differences between the control group and TCDD group (P<0.05). Conclusions The histone H4 acetylation was involved in the cleft palate formation induced by TCDD in C57BL/6J mice.
