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.

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.

Objective: To understand the knowledge, attitude and behavior of HIV/AIDS prevention and treatment of freshmen in Jiangsu Colleges, so as to provide evidence for carrying out HIV/AIDS prevention and treatment propaganda among young college students. Methods: A total of 2 538 freshmen in 8 colleges in Jiangsu province were surveyed by cluster sampling, and anonymous self-reported questionnaire survey was carried out. Valid questionnaires were collected and analyzed. Results: Among 2 538 students valid, the total awareness rate of the eight items of new HIV/AIDS basic knowledge which provided to the public by the State (referred to the new eight items) was 85.74%, the awareness rate of boys was higher than that of girls’(88.21%, 84.34%)(P<0.05), the rate of college students of science was higher that of those of arts(87.31%, 83.67%)(P<0.05). the general awareness rate of other knowledge was 72.14%, and the rate of boys was higher than that of girls(75.00%, 70.53%)(P<0.05). As for "whether eating with the AIDS-affected patients may be affected with AIDS/HIV", boys and students of science were more rational(58.3%, 55.1%; 50.4%, 50.9%)(P<0.05). 50.08% students approved of having sexual behavior before marriage, and the rate of boys was higher than that of girls(69.00%, 39.40%)(P<0.01). 71.24% of the students thought that condoms should be used consistently in sex behaviors, and the proportion of female students (80.76%) was much higher than that of male students(54.37%), and the rate of the students of science was higher than that of students of arts(73.36%, 69.63%)(P<0.05). 6.03% students had received consult and test of AIDS. 40.34% of the untested students were willing to receive the test but didn’t know where to go. 1.34% students were afraid of receiving the test because of fear. The most popular ways of HIV/AIDS publicity among students are micro films(76.32%), lectures(66.67%) and peer education(60.80%). Conclusion It is suggested to publicize HIV/AIDS knowledge among students according to different gender and subject characteristics and combining multimedia, with emphasis on strengthening the publicity of HIV/AIDS epidemiology,treatment and related information, and attaching importance to sexual health education among young students.

OBJECTIVETo analyze the five-year effectiveness of the people living with HIV/AIDS who initially received highly active antiretroviral therapy (HAART) in Jiangsu province.

METHODSHIV/AIDS initially received HAART from 1 Jan 2005 to 31 May 2014 in Jiangsu province with the CD4(+)T cell count tested in baseline, 6 months, 1 year, 2 years, 3 years, 4 years and 5 years after treatment initiation were selected. According to their retrospectively collected baseline and follow-up data, statistical analysis was performed using SPSS 16.0 software to analyze the variation of CD4(+)T counts and its impact factors in different times after treatment initiation.

RESULTSA total of 200 patients were included. A total of 134 patients were men, and 66 were women, the ratio of male to female was 2.03: 1; mean age was (39.7 ± 10.3) years old; 69.0% (138/200) of the patients married; 53.0% (106/200) as the most were infected with HIV through heterosexual transmission, and followed by men who have sex with men (MSM) (25.5%, 51/200); taken together as 78.5% (157/200).58.5% (117/200) were treated in the CDC. The mean (95%CI) baseline CD4(+)T cell count of cases was 106.9 (93.3-120.5) cells/µl; the CD4(+)T count tested in 6 months, 1 year, 2 years, 3 years, 4 years and 5 years after treatment initiation were 107.3, 152.9, 221.6, 260.0, 281.3 and 316.4 cells/µl more than baseline respectively; the CD4(+)T count after treatment initiation has increased over time (F = 201.06, P < 0.01) . The mean(95%CI) CD4(+)T count tested in 5 years after treatment initiation can increase to 540.7(445.4-635.9) cells/µl with a baseline CD4(+)T count more than 200 cells/µl, but in the subgroups with a baseline CD4(+)T count less than or equal to 50 cells/µl, 51-100 cells/µl, 101-150 cells/µl and 151-200 cells/µl, it only can reach to 431.4 (375.9-487.0), 400.0 (339.9-460.2), 380.3 (330.6-430.0) and 412.1 (369.3-454.8) cells/µl respectively. The mean (95%CI) CD4(+)T count tested in 5 years after treatment initiation with 1 baseline symptom categories can increase to 449.2 (392.2-506.2) cells/µl, while 409.1(317.8-500.5)cells/µl in the subgroup with baseline symptom categories more than or equal to 2. The CD4(+)T after treatment increased slowly associated with a lower baseline CD4(+)T count level and more baseline symptom categories (F values were 3.96 and 2.35, P < 0.01).

CONCLUSIONIt has a remarkable effectiveness for HIV/AIDS treatment in Jiangsu province. The patients with a baseline CD4(+)T count more than 200 counts/µl have a better immune function recovery.

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.

Objective To understand the status of recent infected and newly reported HIV cases in Jiangsu province. Methods Information including general demographic,mode of transmission and sample source of newly reported HIV infected cases was collected. Corresponding serum or plasma samples were collected and tested with BED-CEIA. Proportions of recent HIV infections among different populations were calculated,and associated factors of recent HIV infection calculated. Results Among cases infected through different channels as homosexual,heterosexual and needles sharing,the proportions of recent infections were 29.19%,17.40% and 21.75%, respectively. Statistically significant difference was seen between different populations(P<0.05). Compared with female cases,male cases were more likely to be recent infected(OR=1.569,95%CI:1.168-2.107). Compared with cases older than 35 years of age,the ones that younger than that age were more likely to be recently infected(OR=1.556,95%CI:1.289-1.879). Compared with cases who remained single,those married cases were more likely to be long-term infections(OR=0.789, 95%CI:0.649-0.960). Compared with patients identified by hospitals,the recent HIV infections were more likely to be found through voluntary counseling programs and testing(OR=2.278,95%CI:1.853-2.801),project-based surveillance programs(OR=2.409,95%CI:1.860- 3.120),and unpaid blood donation sites(OR=2.911,95%CI:2.118-4.001)(P<0.05). Conclusion Proportion of MSM ranked 1st in the newly reported HIV cases in Jiangsu province. Related HIV case-finding programs should be strengthened to reduce the secondary transmission.

Objective To understand the compliance of highly active anti-retroviral therapy (HAART) and influencing factors in people living with HIV/AIDS (PLWHA) in Nanjing. Methods PLWHA receiving HAART in No. 2 Hospital of Nanjing during May-June 2014 were recruited in this study. Self-administrated questionnaire was used to collect the data about HAART compliance and socio-demographic characteristics of PLWHA surveyed. Descriptive and multivariate statistical analysis were conducted to examine the effects of the factors on self-reported HAART adherence. Results A total of 276 PLWHA were surveyed,According to the evaluation criterion of Center for Adherence Support Evaluation (CASE),252 cases showed good compliance (91.3%). logistic regression analysis revealed that smoking,progress of the disease and side effects,reminding of taking drug and age were correlated with self-reported HAART adherence. Conclusion It is suggested to strengthen the education about antiviral therapy compliance in PLWHA with mild infection and those who are smokers and young,suffer from side effects,have no reminding methods for taking drug.

Objective:Comparing with the external fixator technique, investigate the clinical effect of fixator-assisted plating technique for treatment distal femoral valgus deformity in adolescent.Methods:A retrospective analysis of the relevant data of 22 patients (25 limbs) with acute correction of distal femoral valgus deformities from July 2015 to June 2019, according to the difference of the final fixation, they were divided two groups. The fixator-assisted plating group, including 8 patients (9 limbs), 5 boys and 3 girls, 5 left and 2 right, 1 bilateral, the physis were closed in 4 cases and opened in 4 cases, age 14.04±1.99 years (11.7-18 years). The external fixator group, including 14 patients (16 limbs), 6 boys and 8 girls, 8 left and 4 right, 2 bilateral, the physis were closed in 9 cases and opened in 5 cases, age 13.33±1.88 years (10.1-16.5 years). Measuring the mechanical axis deviation (MAD) and the mechanical lateral distal femur angle (mLDFA) in full length standing AP view X-ray of the lower limb pre and post operation. Recording the changed of limb length discrepancy (LLD) before and after surgery and the knee range of motion at 6 weeks, 3 months, 6 months and the last follow up post operation. The Kolcaba comfort status scale was used to evaluate the comfort of two groups at 2 weeks, 6 weeks, 3 months, 6 months and the last follow up. Meanwhile recorded the healing time of osteotomy sites and the complications.Results:The difference in general information between the two groups was not statistically significant. The fixator-assisted plating group followed up mean 26 months (range, 12-40 months), the healing time were 4.00±0.66 months, the mLDFA mean 73.33°±4.12° before surgery and 87.89°±1.69° after surgery and there was significant difference ( t=10.582, P<0.05). The external fixator group followed up mean 36 months (range, 22-42 months), the healing time were 4.00±0.66 months, the mLDFA mean 73.31°±3.95° before surgery and 87.31°±1.54° after surgery and there was significant difference ( t=14.118, P<0.05). The MAD were in the normal range in all patients after surgery, and there were no significant difference about healing time of the osteotomy sites and postoperative mLDFA between the two groups ( t=1.514, P=0.150; t=0.845, P=0.411). Comparing with the knee function, the fixator-assisted plating group was better at 6 weeks, 3 months, 6 months after surgery but there was no difference at the last follow up. Also, the fixator-assisted plating group felt more comfortable at 2 weeks, 6 weeks, 3 months, 6 months and there was no difference at the last follow up. All the patients with external fixator have mild pin sites infection and there were no obvious complications in patients with plate. Conclusion:The fixator-assisted plating technique can accurately correct the valgus deformity with satisfactory healing of the osteotomy in distal femoral compare with the external fixator technique, but the patients feel more comfortable and the knee joint function recovers faster and no risk of pin site infection, the clinical results was satisfactory with fewer complication.
