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.

OBJECTIVETo study the effects of educational background of men who have sex with men (MSM) on their high risk sexual behaviors and the HIV/STI infection rates.
METHODSDuring July to November of 2009 and March to October of 2010, snowball and convenience sampling methods were adopted to recruit MSM from MSM venues and via the internet in Changzhou city of Jiangsu province, and finally 659 MSM were conducted a questionnaire survey and serological testing. According to the educational background of MSM, they were divided into 3 groups, that is, junior high school group (206 cases), high school group (254 cases), and university group (199 cases). The questionnaire mainly includes information on social demography, sexual behaviors, condom use, etc. Blood samples were collected for HIV and syphilis spirochete detection, and urine samples were also collected in 291 MSM who were recruited during July to November of 2009 for neisseria gonorrhoeae and chlamydia trachomatis nucleic acid detection. χ(2) test and other statistical analysis methods were used to compare the characteristics of sexual behaviors and HIV/STI infections in 3 groups.
RESULTSOf the 659 valid questionnaires returned, junior high school group, high school group, and university group accounted for 31.3% (206 cases), 38.5% (254 cases) and 30.2% (199 cases). Places where MSM of different education levels most often to seek sexual partners, were significantly different. Junior high school group and high school group mostly went to bath house/sauna club (56.3%, 116 cases) and bar (34.8%, 88 cases) for partners, respectively, while the university group sought partners mainly through the internet (41.1%, 81 cases) (χ(2) = 99.35, P < 0.05). 53.4% (109/204) of the junior high school group had anal sex with men in the last 6 months, which was higher than that of high school group (67.7%, 172/254) (χ(2) = 9.74, P < 0.05) and university group (72.7%, 144/198) (χ(2) = 16.04, P < 0.05) . A total of 54.4% (111/204) of the junior high school group had sex with women in the last 6 months, which was higher than that of university group (38.6%, 76/197) (χ(2) = 10.10, P < 0.05) , but was not statistically significantly different from that of high school group (46.9%, 119/254) (χ(2) = 2.59, P = 0.11) . The rates of condom use with men at the last anal sex in junior high school group (73.4%, 80/109) , high school group (78.0%, 131/168) and university group (73.9%, 105/142) were similar. The rates of condom use with women in the last intercourse in junior high school group, high school group and university group were 51.8% (57/110), 54.6% (65/119) and 61.8% (47/76), respectively(χ(2) = 1.88, P = 0.39) . In junior high school group, high school group and university group, the infection rates of HIV were 9.2% (19/206), 10.6% (27/254) and 5.6% (11/197) (χ(2) = 3.68, P = 0.16), the positive rates of neisseria gonorrhoeae were 3.8% (3/79), 3.4% (4/117) and 0.0% (0/95) (χ(2) = 3.85, P = 0.14), the positive rates of chlamydia trachomatis were 5.1% (4/79), 9.4% (11/117) and 4.2% (4/95) (χ(2) = 2.70, P = 0.26). The infection rate of syphilis in junior high school group was 19.9% (41/206), which was higher than high school group (12.2%, 31/254) (χ(2) = 5.11, P < 0.05) and university group (10.2%, 20/197) (χ(2) = 7.45, P < 0.05 ).
CONCLUSIONThere was no obvious correlation between education level and high risk sexual behaviors;MSM with lower education level were at higher risk of infection of syphilis.

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 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:To investigate the efficacy of phenolamine in the treatment of sepsis-induced myocardial dysfunction and its effect on cardiac function, myocardial injury index, and hemodynamics in patients.Methods:The clinical data of 79 patients with sepsis-induced myocardial dysfunction who received treatment in Huangshi Central Hospital, Edong Healthcare Group from February 2017 to February 2020 were retrospectively analyzed. These patients were divided into a control group (without phenolamine treatment, n = 41) and an observation group (with phenolamine treatment, n = 38) according to whether they received phenolamine treatment or not. Clinical efficacy, cardiac function, myocardial injury index, and hemodynamic index pre- and post-treatment were compared between the two groups. Results:There was no significant difference in 28-day mortality rate between the two groups ( P > 0.05). Intensive care unit length of stay and mechanical ventilation duration in the observation group were (9.33 ± 3.52) days and 83.00 (28.50, 138.00) hours, which were significantly shorter than (12.17 ± 4.15) days and 111.00 (47.50, 169.00) hours in the control group ( t = 3.26, Z = -2.27, both P < 0.05). The response rate in the observation group was significantly higher than that in the control group [81.58% (31/38) vs. 60.98% (25/41), χ2 = 4.05, P < 0.05]. After 7 days of treatment, the left ventricular ejection fraction in each group was significantly increased, and the left ventricular end-diastolic diameter and left ventricular end-systolic diameter in each group were significantly decreased compared with before treatment (all P < 0.05). After 7 days of treatment, the left ventricular ejection fraction in the observation group was significantly higher than that in the control group ( t = 3.29, P < 0.05), and left ventricular end-diastolic diameter and left ventricular end-systolic diameter were significantly lower than those in the control group ( t = 5.94, 11.21, both P < 0.05). N-terminal pro-brain natriuretic peptide and cardiac troponin I levels in each group were significantly decreased with time (both P < 0.05). At 24 and 72 hours and 7 days after treatment, N-terminal pro-brain natriuretic peptide and cardiac troponin I levels in the observation group were significantly lower than those in the control group (both P < 0.05). After 7 days of treatment, heart rate in each group decreased significantly compared with that before treatment (both P < 0.05), mean arterial pressure, cardiac index, and stroke output index in each group increased significantly compared with those before treatment (all P < 0.05). After 7 days of treatment, heart rate in the observation group was significantly lower than that in the control group ( t = 4.90, P < 0.05), and mean arterial pressure, cardiac index, and stroke output index in the observation group were significantly higher than those in the control group ( t = 4.37, 3.23, 6.01, all P < 0.05). Conclusion:Phentolamine can improve hemodynamics, reduce myocardial injury and improve cardiac function in patients with sepsis-induced myocardial dysfunction.

Objective:To analyze blood transfusion and prognostic factors of extracorporeal membrane pulmonary oxygenation (ECMO) for the treatment of respiratory and circulatory failure.Methods:The clinical data of 80 patients with respiratory and circulatory failure who received treatment in Huangshi Central Hospital from March 2016 to July 2021 were retrospectively analyzed. According to 28-day prognosis, these patients were divided into death group ( n = 44) and survival group ( n = 36). The general data, blood transfusion during the process of ECMO, vital signs, laboratory indicators, ventilation time, and length of hospital stay were compared between the two groups. The factors affecting death during the process of ECMO were analyzed. Results:There were no significant differences in sex, age, body mass index, complications, the cause of respiratory and circulatory failure, and the mode of ECMO between the two groups (all P > 0.05). Preoperative Acute Physiology and Chronic Health Evaluation II score, creatinine, procalcitonin and lactic acid levels in the survival group were (22.36 ± 3.71) points, (79.17 ± 9.29) μmol/L, (2.77 ± 0.79) ng/L, (2.74 ± 0.36) mmol/L, respectively, which were significantly lower than (34.27 ± 4.98) points, (94.16 ± 10.23) μmol/L, (3.69 ± 1.10) ng/L, (5.18 ± 0.42) mmol/L, respectively in the death group ( t = -11.89, -6.79, -5.62, -27.53, all P < 0.001). There were no significant differences in preoperative respiratory frequency, diastolic pressure, systolic pressure, heart rate, oxygenation index (PaO 2/FiO 2) and C-reactive protein between the two groups (all P > 0.05). The volume of blood transfused on the day of undergoing ECMO, the volume of blood transfused on the day of withdrawing ECMO, the volume of blood transfused during the whole process of ECMO, duration of ventilation, and the incidence of complications related to ECMO were(98.74 ± 16.28) mL, (37.23 ± 10.36) mL, (398.79 ± 67.81) mL, (210.39 ± 20.21) hours, 38.89% (14/36), respectively, which were significantly lower than (160.17 ± 23.14) mL, (48.26 ± 12.25) mL, (600.23 ± 70.12) mL, (320.14 ± 18.21) hours, 79.55% (35/44), respectively in the death group ( t = -13.43, -4.29, 4.94, 25.25, χ2 = 13.79, all P < 0.001). The length of hospital stay in the survival group was longer than that in the death group [(20.14 ± 5.36) days vs. (14.17 ± 4.23) days, t = 5.56, P < 0.001). Acute Physiology and Chronic Health Evaluation II score, procalcition level, the volume of blood transfused on the day of ECMO, duration of ventilation, and the volume of blood transfused during the whole process of ECMO are risk factors for death after ECMO, while length of hospital stay is a protective factor for ECMO. Conclusion:Preoperative evaluation of Acute Physiology and Chronic Health Evaluation II score, continuous blood transfusion during the whole process of ECMO, grasping the opportunity of ventilation and preventing against complications of ECMO are the keys to increasing the survival rate of patients with respiratory and circulatory failure.
