OBJECTIVETo investigate gay identity status of men who have sex with men(MSM) in Xinjiang, and analyze its association with sexual behaviors.

METHODSFrom May to August in 2013, an anonymous questionnaire survey with convenience sampling was conducted among MSM in Urumqi, Kashgar, Aksu and Yining cities of Xinjiang. Those who were ≥ 16 years of age and claimed to have male-to-male sex behaviors were eligible for the survey. A total of 1 467 participants were recruited. Chi square analysis was performed for examining the association between ego-identity, social-identity and relevant sexual behaviors. Selected variables associated with ego-identity, social-identity in the univariate analysis were subsequently assessed in a multivariate analysis using logistic regression.

RESULTSThe MSM with positive ego-identity accounted for 44.7% (656/1 467), and positive social-identity accounted for 29.1% (427/1 467). For ego-identity, Uyghur MSM were less positive than Han MSM (OR (95%CI) was 0.43 (0.32-0.58) ) ; those who were over 20 years of age when accepting their sexual orientation were less positive than those who were younger than 20 years of age when accepting their sexual orientation (OR (95%CI) was 0.61 (0.47-0.80) );and homosexuals were more positive than bisexuals (OR (95%CI) was 1.98 (1.50-2.61) ). For social-identity, Hui MSM were less positive than Han MSM (OR (95%CI) was 0.61 (0.42-0.88) ); those whose education level was higher than college were less positive than those with junior high education (OR (95%CI) was 0.60 (0.40-0.89) ); famers/herdsmen were more positive than students (OR (95%CI) was 4.17 (2.13-8.17) ); the divorced/widowed were more positive than the singles (OR (95%CI) was 2.40 (1.34-4.29) ); those who were over 20 years of age when accepting their sexual orientation were less positive than those who were younger than 20 years of age when accepting their sexual orientation (OR (95%CI) was 0.59 (0.44-0.81) ). Among the MSM with negative ego-identity and negative social-identity, the proportion of planning to get married with women was 66.8% (267/400) and 76.5% (306/400), respectively, which were higher than those with positive ego-identity (33.2% (133/400)) and positive social-identity (23.5% (94/400)) ; their proportion of intending to have offspring was 62.0% (287/463) and 73.4% (340/463), respectively, which were higher than those with positive ego-identity and social-identity (38.0% (176/463), 26.6% (123/463)) (χ(2) = 39.61 and 7.90, respectively, both P values were <0.05). Among the MSM with negative social-identity, the proportion of looking for male sexual partners in toilets or parks was 18.1% (188/1 040), in bathhouse or sauna was 17.3% (180/1 040), and through internet was 82.0% (853/1 040), which were higher than those with positive social-identity (8.9% (38/427), 9.8% (42/427) and 61.6% (263/427)) (χ(2) = 66.78, P < 0.01).

CONCLUSIONIn 2013, the gay identity of MSM in Xinjiang was relatively poor, and the factors associated with it included ethnicity, occupation, marital status and education level. The MSM with negative identity tended to involve in risk sexual behaviors, and had increased risk of HIV infection.

Objective:To explore the association between location of lower extremity deep venous thrombosis and incidence of pulmonary embolism in patients with lower extremity fracture during hospitalization.Methods:A retrospective study was conducted of the 1,620 patients who had been treated for lower extremity fracture and deep vein thrombosis from October 2014 to November 2019 at Department of Orthopaedic Trauma, Honghui Hospital. They were 726 males and 894 females, aged from 18 to 98 years (average, 64.0 years). By the anatomical location of thrombosis, they were divided into a proximal thrombosis group and a distal thrombosis group; by the laterality of thrombosis, they were divided into a bilateral thrombosis group and a unilateral thrombosis group which was further divided into a left thrombosis subgroup and a right thrombosis subgroup. The incidences of pulmonary embolism were compared between 2 corresponding groups and subgroups.Results:Pulmonary embolism occurred in 13 of the 1,400 patients with distal thrombosis and in 12 of the 220 patients with proximal thrombosis; the incidence of pulmonary embolism in the proximal thrombosis group (5.45%, 12/220) was significantly higher than that in the distal thrombosis group (0.93%, 13/1,400) ( P<0.001). Pulmonary embolism occurred in 10 of the 337 patients with bilateral thrombosis and in 15 of the 1,283 patients with unilateral thrombosis; the incidence of pulmonary embolism in the bilateral thrombosis subgroup (2.97%, 10/337) was significantly higher than that in the unilateral thrombosis group (1.17%, 15/1,283) ( P=0.017). Pulmonary embolism occurred in 5 of the 677 patients with left thrombosis and in 10 of the 606 patients with right thrombosis; the incidence of pulmonary embolism in the right thrombosis subgroup (1.65%, 10/606) was insignificantly higher than that in the left thrombosis subgroup (0.74%, 5/677) ( P=0.129). Conclusions:In patients with lower extremity fracture, those with proximal or bilateral thrombosis are more prone to pulmonary embolism than those with distal or unilateral thrombosis, but the possibility of pulmonary embolism cannot be ignored clinically in those with distal or unilateral thrombosis.

Objective To analyze the sex specific mortality in HIV/AIDS patients receiving highly active antiretroviral therapy (HAART) and risk factors in Xinjiang Uyghur autonomous region (Xinjiang),and provide evidence for the evaluation of the effect of HAART.Methods A retrospective analysis was conducted on the mortality and survival of 8 061 male cases and 6 001 female cases of HIV infection,who received HAART during July 2004-June 2013 in Xinjiang.The information of the cases were downloaded from national antiretroviral therapy reporting sub-system in national HIV/AIDS reporting system.Cox proportional hazard model was used to identify the risk factors of deaths.Results The male cases were older and had lower CD4 value at baseline compared with the female cases.The major transmission route was injecting drug use in males,but sexual contact in females.The overall mortality of the male cases was higher than that of the females,which was 10.87/100 person-years during the first three month after receiving HAART,and 7.00/100 person-years two years later in males,but 4.77/100 person-years during the first three month and 3.00/100 person-years two years later in females.The results from Cox analysis showed that the risk factors were the CD4 value at baseline and transmission route.Compared with the cases who had lower CD4 value (CD4＜200 cells/μl) at baseline,the HR for the cases who had higher CD4 value (CD4 ≥ 350 cells/μl) was 4.08 (95％ CI:2.96-5.62) in males and 5.11 (95％CI:3.16-8.35) in females.Compared with sexual transmission,the HR for IDUs was 1.99 (95％CI:1.66-2.40) in males and 1.77 (95％ CI:1.24-2.52) in females.The results of cumulative survival analysis showed that in conventional treatment group (CD4＜350 cells/μl),the five year survival rates were 81％ and 87％ for the males and females infected through sexual contact and 66％ and 75％ for the males and females infected through injecting drug use,and in early treatment group (CD4≥350 cells/μl),the five year survival rates were 97％ and 98％ for the males and females infected through sexual contact and 86％ and 97％ for the males and females infected through injecting drug use.Conclusion In Xinjiang,the higher mortality in male HIV infection cases receiving HAART was related with lower CD4 value at baseline and higher infection rate through injecting drug use.Besides the weak intention for treatment and poor compliancy would be the deeper risk factors.

Objective To understand the misreporting rate regarding the routes of transmission among the reported HIV patients in Yili prefecture of Xinjiang,since 2011.Methods An investigation focusing on the route of transmission among people living with HIV/AIDS was carried out to clarify the responsible reasons for the situation.Results The overall incorrect reporting rate on the route of transmission was 10.8％.The proportion of heterosexual transmission route was over estimated by 63.8％ to 72.0％.However,the proportion of injecting drug was underestimated by 27.5％ to 22.2％.The number of cases being confirmed as through heterosexual transmission but incorrectly reported was quite high,contributing 82.6％ of all the incorrectly reported cases.Most of the patients that incorrect reported,were moved from injecting drug use to heterosexual transmission,which contributed 79.5％ of all the total incorrectly reported cases.Results from multi-factor analysis showed that the risk related to incorrect reporting was 3.64 times in males than in females.People who anticipated to receive HIV testing were 2.23 times more than those who had not.Old-age groups were 3.511,4.053,4.415 and 6.524 times higher than those people who were aged below 16 years.Conclusions The proportion of heterosexual transmission route was over-estimated while the proportion on injecting drug use was underestimated.However,the transmission pattern had changed from injecting drug use at the early epidemic stage,to current sexual transmission mode.We recommended that more attentions should be paid to patients who were males,at older age or those who had no expectation in receiving the HIV testing,during the initial following-up stage.

OBJECTIVETo analyze the mortality and risk factors among HIV/AIDS patients receiving highly active antiretroviral therapy (HAART) in the Xinjiang Uyghur Autonomous Region (XUAR).

METHODSThe objects of study were all HIV/AIDS adult patients who had received HAART in XUAR. The proceeding information was uploaded to the national ART reporting system which was a branch of the national HIV/AIDS reporting system. A retrospective cohort study was conducted among these patients who were treated during July 2004 to June 2013 in XUAR. Mortality rates and cumulative survival rates were calculated. Cox proportional hazard model was conducted to examine the risk factors for deaths.

RESULTSThe proportion for death, lost, referral and withdrawal were 8.5% (1 200/14 062), 2.5% (351/14 062), 0.9% (121/14 062)and 15.4% (2 162/14 062) respectively. The P25, P50 and P75 of baseline CD4(+)T lymphocyte was 144.00, 244.50 and 331.00/µl, respectively. The overall mortality rate was 4.98/100 person-years. The cumulative survival rate of ART treatment after 1-5 years were 0.94,0.91,0.88, 0.84 and 0.81. The mortality rate had a significant difference among different population. The male (6.58/100 person-years) was higher than the female(2.87/100 person-years), the people who infected tuberculosis (TB) (9.79/100 person-years) was higher than those non TB (4.12/100 person-years), the people whose CD4(+)T lymphocyte count less than 200/µl (7.67/100 person-years) was higher than other groups, the people who were transmitted through injection (7.61/100 person-years) was higher than those sexual transmission (3.10/100 person-years), the people whose HB less than 80 g/L (13.84/100 person-years) was higher than those more than 80 g/L (4.74/100 person-years) (χ(2) values were 154.62, 177.47, 309.73, 228.99 and 84.27. P < 0.01). The risk of death of the one with the baseline CD4(+)T lymphocyte ≤ 200/µl was 3.61 (2.73-4.78) times of the one with the baseline CD4(+)T lymphocyte >350/µl. The risk of death of the one having more than 4 baseline symptom categories was 3.62 (2.42-5.42) times of the one having less than 3 baseline symptom categories. The risk of death of the one with baseline HB ≥ 80 g/L was 2.84 (2.21-3.64) times of the one with the baseline HB <80 g/L. The risk of death of the male was 1.48 (1.25-1.75) times of the female. The risk of death of the one infected TB was 1.39(1.18-1.64) times of the one not infected TB. The risk of death of the one injecting drugs was 1.84 (1.56-2.17) times of the one not injecting drugs.

CONCLUSIONFrom 2004 to 2013, the mortality rate was low among HIV/AIDS patients receiving ART in XUAR. The mortality risk factors were low CD4 T cell count, having more baseline symptom categories, low HB level, injection drug transmission, male and TB infection, all these factors had positive correlation with death.

Objective:To evaluate the effects of weight-bearing area compression injury of the femoral head on the prognosis of elderly acetabular fractures after open reduction and internal fixation.Methods:A retrospective analysis of 36 elderly patients with acetabular fractures treated with open reduction and internal fixation during January 2014 to January 2018 were conducted. All patients with compression injury of the weight-bearing area of the femoral head, including 22 males and 14 females with 73.2±6.5 years old (range 60-87 years old), were included. The compression injury of weight-bearing area of the femoral head was not treated. According to the Letournel-Judet classification of acetabular fractures, there were 14 cases with both-column, 12 cases with anterior column and posterior hemitransverse, 4 cases with T type, 4 cases with transverse, and 2 cases with posterior column+ posterior wall. A total of 14 cases were accompanied by acetabular joint surface compression, while 29 cases were accompanied by joint dislocation. The Merle d'Aubigné score was used to evaluate the hip function during follow-up. The Matta classification method was used to evaluate the results of acetabular fracture reduction. The Kellgren-Lawrence classification standard and Ficat-Alert staging method were used to evaluate the traumatic arthritis of the hip and femoral head necrosis, respectively. During the follow-up, the femoral head necrosis with stage III, IV, or traumatic arthritis III, IV, or with indications for joint replacement was defined as surgery failure. CT scans of the pelvis were performed before and at 2-5 days after operation. The compression size of the femoral head on the coronal and axial planes of the CT scan was calculated for the compression volume. The compression severity was divided into small (<1 cm 3), medium (1-2 cm 3) and large (>2 cm 3) according to the volume. Binary Logistic regression analysis was used to analyze whether the postoperative measurement of the femoral head compression volume was associated with the risk of surgical failure. Results:All patients were followed up for 34.7±8.9 months (range 25-54 months). There were 7 cases with large compression of femoral head, 14 cases with medium, and 15 cases with small pre-operatively. However, there were 12 cases, 10 cases and 14 cases with large, medium and small at 2-5 days after operation, respectively. Six cases were excellent reduction, 22 cases were good, and 8 cases were poor. Thus, the excellent and good rate was 78% (28/36). At the last follow-up, Merle d'Aubigné score was excellent in 2 cases, good in 8 cases, fair in 5 cases, and poor in 21 cases. The excellent and good rate was 28% (10/36). There were 20 cases with surgery failure with 56% (20/36) failure rate. There were no statistically significant differences in the patient's age, body mass index, operation duration, blood volume, fracture type, fracture reduction, combined acetabular joint surface compression, and combined joint dislocation between the two groups. However, there was a statistically significant difference in the frequency distribution of compression volume in the weight-bearing area of the femoral head after surgery (χ 2=22.047, P<0.001). In patients with large, medium, and small-volume compression of the femoral head weight-bearing area, the surgery failure rates were 92%, 80%, and 7%, respectively. The large and medium-volume compression of the femoral head weight-bearing area were independent risk factors for surgical failure. Conclusion:Open reduction and internal fixation can be used to treat elderly patients with acetabular fractures combined with femoral head compression injury. Despite satisfactory reduction for acetabular fractures, the larger volume of femoral head compression affects the clinical outcomes with extremely high rate of surgical failure within 2 years.

Objective To investigate the superinfection of human immunodeficiency virus (HIV) / hepatitis B virus (HBV) in Yining City, and to study on its prevention and control measures. Methods A total of 21 cases of HIV / HBV superinfection recorded by Yining CDC from January 2017 to October 2019 were investigated. Results In this group, the proportion of male (66.67%) was higher than that of female (33.33%), 36-60 years old and 17-35 years old (42.86% and 33.33%), junior high school and primary school and below (57.14% and 28.57%), sex workers and migrant workers (42.86% and 28.57%) were higher. The common clinical manifestations of this group were long-term fever, emaciation, general pain and so on. HIV was mainly sexually transmitted (61.90%). HBV was mainly transmitted by blood and sex (47.62% and 9.52%). The proportion of big three Yang was the highest (42.86%), followed by simple HBsAg (23.81%), small three yang (19.05%), HBsAg / anti HBC (14.29%). Conclusion In Yining City, 36-60 years old of male, junior high school and below, sex workers and migrant workers account for a relatively high proportion, and their clinical manifestations were complex, with clear features. Therefore, prevention and management should be strengthened.
