ABSTRACT
Objective@#To understand the incidence and related factors of HIV-1 drug resistance among HIV/AIDS patients experiencing treatment failure in Jiangsu province, China.@*Methods@#The HIV/AIDS integrated prevention and control data information management system of China were used to collect the basic data of patients, blood specimens were collected from patients who had antiretroviral therapy (ART) failure with ≥12 months and older than 18 years in 2016 in Jiangsu, excluding cases with missing information, 713 cases were enrolled in this study. HIV-1 RNA was extracted, and then pol gene region was amplified and sequenced. The obtain sequences were submitted to Stanford University HIV Drug Resistance Database to interpret and analyse HIV-1 drug resistance and sub-types. Multivariate logistic regression model was used to explore the related factors of drug resistance.@*Results@#A total of 579 subjects were amplified successfully, male accounted for 85.66% (496 cases), and the median age was 39 years old. The main route of infection was sexual transmission (553 cases, 95.51%). A total of 331 patients with drug resistance gene mutation were detected, drug resistance mutation rate was 57.18%. Compared with patients with baseline CD4+T cell count >500 cells/μl, patients with CD4+T cell count in 201-500 cells/mm3 and ≤200 cells/μl had a higher incidence of genetic drug resistance, the odds ratio was 3.33 and 6.87, respectively. Compared with patients with treatment less than 24 months, patients treated for 25-48 months had a higher incidence of drug resistance, the odds ratio was 1.88. Compared with patients infected by CRF07_BC strains, patients infected by CRF01_AE strains were associated with higher incidence of drug resistance, the odds ratio was 2.22 and 3.32, respectively. Protease inhibitor (PI) resistance mutations, nucleoside reverse transcriptase inhibitor (NRTI) and non-nucleoside reverse transcriptase inhibitor (NNRTI) were found in 3.80%, 33.16% and 53.37% of patients, respectively. 31.95% of patients harbored NRTI and NNRTI resistance mutations simultaneously. M184V/I and K103N/Q were the highest frequency of NRTI and NNRTI resistance mutation, the prevalence of M184V/I and K103N/Q were 28.15% and 22.28%, respectively.@*Conclusion@#The status of HIV-1 drug resistance mutations are complex and diverse among patients experiencing failure of ART in Jiangsu. Patients with lower baseline CD4+T cell count, longer treatment time and HIV-1 CRF01_AE and B strains infection were associated with higher incidence of drug resistance mutation.
ABSTRACT
At present, China's AIDS testing increased rapidly, but there are still many people living with HIV do not recognize their status, thus postponing the antiviral treatment time. HIV self-testing (HST) is an effective method to expand the testing, not only simple operation, easy to get a result, effectively protect the detection privacy, expand the selection of testers, suit to the entire population, but also the premise and basis of other AIDS comprehensive prevention measures, all over the world are promoting it. Because the HST has controversies in the window period, price and before and after controversial, and our country is in the initial stage of HST, so it is not to develop related policies, but more and more countries are in accordance with their own situations are modified or developed to allow to use rapid detection of AIDS policy to regulate the field. This paper analyzed and summarized the advantage and influence factors of HST promotion, HST believes that in the long term, the advantages outweigh the disadvantages, we need to formulate relevant policies, and improve the sensitivity of the kit, shorten the window period of time, production and promotion of operation standard of video, specification and testing the operating practices, preventing and reporting the possible social harm, investigation and understanding of the needs of the people of the crowd, to maximize the advantages of HST, find more infection, so as to curb the epidemic of AIDS.
ABSTRACT
<p><b>OBJECTIVE</b>To understand the economic burden caused by antiretroviral treatment for people living with HIV/AIDS and influencing factors in Nanjing.</p><p><b>METHODS</b>People living with HIV/AIDS were divided into two groups, HIV infected patients and AIDS patients. The data about their direct medical expenditure, direct non-medical expenditure and indirect economic loss in the past year were collected. Univariate and multivariate analysis were conducted to identify the potential influencing factors.</p><p><b>RESULTS</b>The median of direct medical expenditure and total costs for 133 HIV infected patients were 1,200 yuan RMB and 1,972 yuan RMB respectively. The median of direct medical expenditure and total costs for 145 AIDS patients were 1 060 yuan RMB and 2 826 yuan RMB respectively. The differences in direct medical expenditure and total costs between HIV infected patients and AIDS patients showed no statistical significance. The results from univariate analysis indicated that the sample source influenced total costs significantly. Multivariate analysis showed that onset time and CD level were negatively correlated with direct medical expenditure. The patients infected through heterosexual contact had more direct medical expenditure than those infected through homosexual contact. The patients receiving HIV test in hospitals had more direct medical expenditure than those receiving volunteer counseling and testing.</p><p><b>CONCLUSION</b>Further efforts should be made to expand HIV testing and treatment coverage in order to detect HIV infections as early as possible. Early antiretroviral treatment should be given to HIV infected patients to maintain their immunity and reduce their medical expenditure.</p>

The study was to observe the therapeutic effect of HJ-1 NO--HFJV respirator on treating pulmonary edema caused by seawater drowning. Seawater was infused into the rabbit's lung to establish the animal model of pulmonary edema caused by seawater drowning(PE-SWD). Then the animals were divided into three groups: simple PE-SWD model as control group, treat group(animal model treated with HFJV respirator and four medicines) and HFJV respiratior plus NO group. Pao2, Sao2 and pH were measured by the blood-gas analyzer. The survival time and seawater drowing-respiratiory distress syndrom(SW-RDS) were observed. The results showed that Pao2, Sao2 in NO group were remarkably higher than that of PE-SWD control group, and the survival time was longer than that of medicine treated group and the incidence of SW-RDS decreased to zero. We assume that HJ-1 NO-HFJV respirator is efficient on treating pulmonary edema.
