Correlation between negative life events and suicide attempts among Yi adolescents with HIV/AIDS in Liangshan Prefecture.

OBJECTIVE: To investigate the incidence of suicide attempts among adolescents with HIV/AIDS in Liangshan Prefecture, Sichuan Province, as well as the correlation between negative life events, sleep, exercise, drug therapy and suicide attempts. METHODS: A total of 180 Yi adolescents aged 11-19 years with HIV/AIDS in a county of Liangshan Prefecture, Sichuan Province, China, were investigated by census. The main outcome indicators included the incidence of suicide attempts and whether negative life events, sleep, exercise, drug therapy and other factors were related to suicide attempts. RESULTS: We found that the incidence rate of suicide attempts among Yi adolescents with HIV/AIDS in Liangshan Prefecture was 13.9%. Negative life events were a risk factor for suicide attempts (OR = 1.047, p < 0.001, 95% CI 1.027-1.067). In the factors of negative life events, adaptation was a risk factor for suicide attempts (OR = 1.203, p = 0.026, 95% CI 1.022-1.416), and academic pressure showed a tendency to be a risk factor for suicide attempts (OR = 1.149, p = 0.077, 95% CI 0.985-1.339). However, the punishment factor, interpersonal stress factor and loss factor had no significant correlation with suicide attempts. There was no significant correlation between sleep, exercise, drug therapy and suicide attempts. CONCLUSION: The proportion of suicide attempts among Yi adolescents with HIV/AIDS in Liangshan Prefecture is high and should be considered. Negative life events are independent risk factors for suicide attempts, and it is necessary to strengthen the screening and early intervention for suicide attempts in HIV/AIDS adolescents with definite negative life events.

ObjectiveTo explore the mental health status and its influencing factors among middle school students in Xide County， Liangshan Yi Autonomous Prefecture， and to provide references for mental health interventions for local middle school students. MethodsUsing a cross-sectional study design， one junior middle school and one senior middle school in Xide County， Liangshan Prefecture， Sichuan Province， were randomly selected on September 16， 2021， and two classes per grade in each school involving 288 students were recruited. Subjects were assessed using Patients' Health Questionnaire Depression Scale-9 item （PHQ-9）， Generalized Anxiety Disorder Scale-7 item （GAD-7）， PTSD Checklist for DSM-5 （PCL-5）， Multidimensional Scale of Perceived Social Support （MSPSS） and UCLA Loneliness Scale （ULS-3）. Then the scores of above scales were compared among middle school students with different demographic characteristics， and binary Logistic regression analysis was conducted to screen the influencing factors of post-traumatic stress disorder (PTSD） symptoms. ResultsAmong the respondents， 17.71% （95% CI： 0.133~0.221）， 8.68% （95% CI： 0.054~0.120）， 2.78% （95% CI： 0.009~0.047） and 45.83% （95% CI： 0.400~0.516） were reported to have symptoms of depression， anxiety， PTSD and loneliness， respectively. Students in senior middle school scored lower on PCL-5 and ULS-3 than those in junior middle school ［（6.46±8.91） vs. （8.87±9.42）， t=2.202， P<0.05； （4.67±1.65） vs. （5.60±1.88）， t=4.431， P<0.01］. Regression analysis denoted that depressive symptoms （OR=7.630， P<0.05） and anxiety symptoms （OR=3.789， P<0.01） were risk factors for PTSD symptoms among middle school students. ConclusionThe middle school students in Xide County， Liangshan Yi Autonomous Prefecture suffer a high prevalence rate of depressive symptoms and loneliness， and those in junior middle school are more likely to feel a sense of strong loneliness， furthermore， depressive symptoms and anxiety symptoms are risk factors for PTSD symptoms.

Comparative analysis of antigen coding genes in 15 red cell blood group systems of Yunnan Yi nationality in China: A cross-sectional study.

Introduction: There are few analyses of the 15 red blood group system antigen coding genes found in the Yunnan Yi nationality. This has caused many poteintial dangers relating to clinical blood transfusion. In this report, the coding genes and distribution of 15 blood group antigens system in the Yi nationality were tested and compared with those of Han nationality and other ethnic minorities. Methods: The samples came from the healthy subjects in the first people's Hospital of Qujing, Yunnan Province. Two hundred and three Yunnan Yi and 197 Han nationality individuals were included. Thirty-three blood group antigens with a low frequency from the 15 blood group systems of Yunnan Yi blood donors were genotyped and analyzed by PCR-SSP. Sanger sequencing was used to detect A4GALT from the Yunnan Yi nationality. The χ 2 test was used to analyze observed and expected values of gene distribution to verify conformation to the Hardy-Weinberg equilibrium law. Fisher's exact test was used to analyze gene frequency distribution, and the statistical significance was set at p < 0.05. Results: The ABO blood group examination results for the Yi nationality and the local Han nationality in Qujing City, Yunnan Province, showed the majority were type A and type O, while the least prevalent was type AB. RhD+ accounts for more than 98% of the Yi and Han populations. There was a significant difference in ABO blood group antigen distribution between these two nationalities (p < 0.05), but there was no significant difference in the composition ratio of D antigen in the Rh blood group system (p > 0.05). Compared with Tibetan (Tibet), Zhuang (Nanning), and Dong (Guangxi), the gene distribution frequencies of Rh blood group system phenotype CC were significantly lower in the Yunnan Yi nationality (p < 0.05). There were significant differences in six erythrocyte phenotypic antigens in the Yi nationality in Yunnan compared with Han nationality, such as LW(a-b-), JK(a-b+), MMSs, Di(a-b+), Wr(a-b-), and Kp(a-b+) (p < 0.05). There were gene phenotypes with a low frequency in the four rare blood group systems: LW, MNS, Wright, and Colton. Several different mutation types occurred in the P1PK blood group system's A4GALT gene. Conclusion: Yunnan Yi nationality has a unique genetic background. There are some significantly different distributions of blood group system genes with a low frequency in different regions and groups in China. Multiple mutations in the A4GALT gene of the P1PK blood group system may be related to their environment and ethnic evolution.

Cardiac Disease Associated Genetic Variants in Yi Nationality in Regions with High Incidence of Yunnan Sudden Unexplained Death.

ABSTRACT: Objective To explore the association of cardiac disease associated genetic variants and the high incidence of Yunnan sudden unexplained death （YNSUD） in Yi nationality. Methods The genomic DNA was extracted from peripheral blood samples collected from 205 Yi villagers from YNSUD aggregative villages （inpatient group） and 197 healthy Yi villagers from neighboring villages （control group）. Fifty-two single nucleotide variants （SNVs） of 25 cardiac disease associated genes were genotyped using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry （MALDI-TOF-MS）. The SPSS 17.0 was used to analyze data. The pathogenicities of variants with differences between the two groups that have statistical significance were predicted by protein function prediction software PolyPhen-2 and SIFT. All villagers from inpatient group were given electrocardiogram （ECG） examination using a 12-lead electrocardiograph. Results The allele frequency and the genotype frequency of missense mutation DSG2 （rs2278792, c.2318G>A, p.R773K） of pathogenic genes of arrhythmogenic right ventricular cardiomyopathy （ARVC） in inpatient group was higher than that in control group （P<0.05）. Abnormal ECG changes were detected in 71 individuals （34.6%） in the inpatient group, among which 54 individuals carried R773K mutation, including clockwise （counterclockwise） rotation, left （right） axis deviation, ST segment and T wave alteration and heart-blocking. Conclusion Definite pathogenic mutations have not been found in the 52 cardiac disease genes associated SNVs detected in Yi nationality in regions with high incidence of YNSUD. The cause of high incidence of YNSUD in Yi nationality needs further study.

Identification of Active Compounds From Yi Nationality Herbal Formula Wosi Influencing COX-2 and VCAM-1 Signaling.

The Yi nationality herbal formula Wosi is used in China as a folk medicine to treat arthritis and related diseases. Despite its widespread use, the active ingredients, and pharmacological mechanisms are not performed. This is the first time to identify the active compounds from Wosi with the aim at providing the potential effect of Wosi and exploring its underlying anti-inflammatory mechanism in monosodium urate crystals (MSU)-induced arthritis rats. In this study, anti-hyperuricemia effect was assessed by reducing the serum uric acid levels and increasing uric acid excretion in the urine for the hyperuricemia rat model. Wosi significantly suppressed the degree of joint swelling and improved the symptoms of inflammation induced by MSU crystals. The inhibition of IL-2, IL-1ß, IFN-γ, and IL-6 secretion and IL-10 increase in the serum were also observed. This study also focuses on the screening of the main compounds from Wosi against cyclooxygenase for anti-inflammatory properties using molecular docking. The result showed 3-O-[α-L-pyran rhamnose(1-3)-ß-D-pyran glucuronic acid]- oleanolic acid, 3-O-(ß-D-pyran glucuronic acid)-oleanolic acid-28-O-ß-D-pyran glucoside, and 3-O-[α-L-pyran rhamnose(1-3)-ß-D-pyran glucuronic acid]-oleanolic acid-28-O-ß-D-pyran glucoside with a higher binding affinity for COX-2 than COX-1 which indicated relatively higher interaction than COX-1. The preferential selectivity toward inhibiting COX-2 enzyme over COX-1 of three compounds from Wosi were evaluated using in-vitro cyclooxygenases 1 and 2 (COX-1/2) inhibition assays. Meanwhile, the down-regulated protein expression of COX-2 and VCAM-1 in synovial tissue sections from ankle joints of experiments rats were confirmed by immunohistochemistry analysis after the Wosi treatment. In conclusion, three oleanolic acid glycosides were implied as mainly efficient compounds in Yi nationality herbal formula Wosi for arthritis therapy via selectively influencing COX-2 and VCAM-1 signaling.

[Predictive Value of Obesity Indicators for Metabolic Syndrome in Adults of Han and Yi Nationalities in Sichuan].

OBJECTIVE: To compare the predictive value of different measures of obesity for metabolic syndrome (MetS) in adult Yi and Han nationality population. METHODS: A total of 3 492 urban and rural residents in Chengdu and Liangshan Yi Autonomous Prefecture participated in this study. Demographic and laboratory data were collected. Spearman correlation analysis was used to investigate the relationship between different obesity measurement indexes and MetS. Receiver operating characteristic (ROC) curve was used to compare the predictive value between different obesity measurement indexes. RESULTS: Spearman correlation analysis showed that MetS was related to body mass index (BMI), waist circumference (WC), waist-to-hip ratio (WHR), waist-to-height ratio (WHtR), lipid accumulation index (LAP) and visceral adiposity index (VAI). The ROC curve showed that the LAP had the highest predictive value for MetS in both Yi and Han male adults, area under the curves (AUCs) >0.90; whereas WHR had the lowest predictive value. WHtR had high predictive value for MetS in both Yi and Han female adults (AUCs >0.88), VAI had the worst predictive value. CONCLUSION: Among different measures of obesity, LAP may have the optimal predictive value for MetS in male adults as do WHtR in female adults either in Yi or Han nationality. These findings should be confirmed through the measure of visceral fat volume and prospective study.

[Investigation on prevalence and risk factors of HIV/AIDS and Schistosoma japonicum, Ascaris lumbricoides and Trichuris trichiura infections in a rural community of southwestern China].

OBJECTIVE: To investigate the prevalence and risk factors of helminthic infections including Schistosoma japonicum, Ascaris lumbricoides and Trichuris trichiura and human immunodeficiency virus (HIV), and find out the association among them in a rural community of southwestern China. METHODS: A community-based cross sectional study was conducted. One town was selected randomly; the infections of S.japonicum, A.lumbricoides and T.trichiura were detected with the modified Kato-Katz thick smear method and HIV infection with the diagnostic Test Kit among all residents. A questionnaire survey was conducted to investigate the related risk factors. RESULTS: Among the participants, the infection rates of HIV, S.japonicum, A.lumbricoides and T.trichiura were 2.33%, 2.05%, 13.47% and 30.59% respectively; 7.08% (31/438) were infected with both A.lumbricoides and T.trichiura; 0.23% (1/438) were co-infected with HIV and A.lumbricoides, and the same with HIV and T.trichiura. The multivariate logistic regression analysis showed that sex (male, OR=3.26, 95% CI：0.97, 10.95) and drug abuse (OR=72.86, 95% CI：18.51, 286.76) were significantly associated with HIV infection. Home toilet was negatively related to A.lumbricoides infection (OR=0.52, 95% CI：0.27, 0.98) and T.trichiura infection (OR=0.48, 95% CI：0.28, 0.80). Compared with the people in Villages Four, the people living in Village One were at a higher risk for A.lumbricoides infection (OR=3.14, 95% CI：1.35, 7.27), and compared with the people living in Village Four, the people living in Village Two and Village Three were more likely to be infected with T.trichiura (OR=3.73, 95% CI：1.92, 7.26; OR=4.53, 95% CI：2.12, 9.68). The people aged between 11 and 20 years had a higher T.trichiura infection risk than the people aged more than 50 years (OR = 3.72, 95% CI：1.59, 8.67). There was a significant association between A.lumbricoides and T.trichiura infections (OR = 3.11, 95% CI：1.63, 5.93). There was no association between S.japonicum infection and related factors above mentioned. CONCLUSIONS: The infection rates of HIV, S.japonicum, A.lumbricoides and especially T.trichiura were rather high in this area, and therefore, the prevention and treatment of these diseases should be strengthened. Further studies on the relationship between HIV and the infections of helminths, especially S.japonicum are needed.

Objective To investigate the correlation of the polymorphisms of angiotensin Ⅱtype 1 receptor (AT1R)gene A1166C and angiotensinogen(AGT)gene M235T and blood biochemical indicators with essential hypertension(EH)in the male of Yi nationality in Yunnan province. Methods 92 hypertensive and 70 normotensive of Yi people were recruited in Yunnan province. Their basic information and blood biochemical indicators were obtained by questionnaire and standardized physical examination. The genes polymorphisms were determined by polymerase chain reaction-restriction fragment length polymorphism(PCR-RFLP)technique. Results(1)For the male EH patients of Yi nationality,1166C and 235T allele frequencies were 0.038 and 0.772. No significant differences in allele frequency or genotype frequency were observed between the two groups(P > 0.05).(2)The levels of TC,LDL-C and TG in EH were significantly higher than those in controls(P < 0.05). Conclusion The AT1R A1166C and AGT M235T polymorphisms were not related to the pathogenesis of EH in the male of Yi people. However,the high levels of TC,TG and LDL-C might be the risk factors of EH.
