Objective To investigate the vaccination status and vaccination willingness of novel coronavirus in HIV/AIDS population in Yunnan.Methods From October 2021 to June 2022,a questionnaire survey was conducted among 2180 HIV/AIDS patients in Kunming,Qujing,Yuxi,Zhaotong,Puer,Baoshan,Lincang,Honghe,Wenshan,Xishuangbanna,Dali,Dehong and Nujiang prefectures.The questionnaire included age,sex,education,nationality,education level,vaccination,adverse reactions within 7 days after the vaccination,safety of COVID-19 vaccine,awareness of effectiveness,vaccination willingness and so on.Results Among the subjects,2109 completed 3 injections,accounting for 96.74%,and 71 were not vaccinated,accounting for 3.26% .Within 7 days of inoculation,local adverse reactions occurred in 116 cases,accounting for 5.50%,and systemic adverse reactions occurred in 56 cases,accounting for 2.66% .Injection site pain,fatigue and muscle pain accounted for the highest proportion of adverse symptoms in different sex,age and the Han nationality,while the proportion of minority adverse reactions was very low,and there was no difference among the different sex and age(P>0.05).The main reasons for the reluctance of HIV/AIDS population to be vaccinated were(recommended by doctors)that HIV/AIDS patients could not be vaccinated(67.61%)and may have serious adverse reactions after the vaccination(19.72%).The factors affecting the vaccination were found by logistic regression analysis,whether they were worried about infecting novel coronavirus(OR = 0.121,95% CI = 0.083~0.640,P<0.001)and how much they knew about COVID-19 vaccine(OR = 28.932,95% CI = 15.469~54.115,P<0.001),safety of vaccination(OR = 13.953,95% CI = 4.819~40.404,P<0.001)and belief in the preventive effect of vaccine(OR = 14.017,95% CI = 4.752~41.348,P<0.001)were significant factors affecting vaccination.Among the 13 prefectures and cities,Dehong(20),Zhaotong(21)and Lincang(14)had the largest number of unvaccinated people.Conclusion After the mass vaccination,the rate of adverse reaction in HIV/AIDS population is low,the symptoms are mild,the correct and scientific advice and guidance from doctors and the full understanding of the harmfulness of the disease,the safety,prevention and effectiveness of the vaccine are the key to complete vaccination and put an end to vaccine hesitancy.

BACKGROUND:
This study aimed to evaluate the correlation between long non-coding RNA (lncRNA)-related single nucleotide polymorphisms (SNPs) and susceptibility to silicosis.
METHODS:
First, RNA-sequencing (RNA-seq) data were comprehensively analyzed in the peripheral blood lymphocytes of eight participants (four silicosis cases and four healthy controls) exposed to silica dust to identify differentially expressed lncRNAs (DE-lncRNAs). The functional SNPs in the identified DE-lncRNAs were then identified using several databases. Finally, the association between functional SNPs and susceptibility to silicosis was evaluated by a two-stage case-control study. The SNPs of 155 silicosis cases and 141 healthy silica-exposed controls were screened by genome-wide association study (GWAS), and the candidate SNPs of 194 silicosis cases and 235 healthy silica-exposed controls were validated by genotyping using the improved Mutiligase Detection Reaction (iMLDR) system.
RESULTS:
A total of 76 DE-lncRNAs were identified by RNA-seq data analysis (cut-offs: fold change > 2 or fold change < 0.5, P < 0.05), while 127 functional SNPs among those 76 DE-lncRNAs were identified through multiple public databases. Furthermore, five SNPs were found to be significantly correlated with the risk of silicosis by GWAS screening (P < 0.05), while the results of GWAS and iMLDR validation indicated that the variant A allele of rs1814521 was associated with a reduced risk of silicosis (OR = 0.76, 95% CI = 0.62-0.94, P = 0.011).
CONCLUSION
The presence of the SNP rs1814521 in the lncRNA ADGRG3 is associated with susceptibility to silicosis. Moreover, ADGRG3 was found to be lowly expressed in silicosis cases. The underlying biological mechanisms by which lncRNA ADGRG3 and rs1814521 regulate the development of silicosis need further study.

OBJECTIVE To establish an analytical method based on ultra-performance liquid chromatography-quadrupole-time- of-flight mass spectrometry (UPLC-Q-TOF/MS) combined with UNIFI platform for rapid identification of the chemical constituents in Abrus cantoniensis Hance. METHODS The chromatographic separation was performed on ACQUITY PRM HSS T3 FIT column for gradient elution with the mobile phase consisted of 0.1% formic acid aqueous solution-acetonitrile. The flow rate was 0.3 mL/min, and injection volume was 2 μL. Electrospray ionization was used to collect the mass spectrometry data of the chemical constituents of A. cantoniensis Hance with full information tandem mass spectrometry technology in positive and negative ion modes. The chemical constituent database of A. cantoniensis Hance was established. Targeted and non-targeted analyses were conducted based on UNIFI platform, and chemical constituents were further identified in combination with accurate molecular mass, secondary fragment ion information and equivalence with reference substances and literature data, etc. RESULTS Totally 46 compounds of A. cantoniensis Hance were successfully identified, including 19 flavonoids, 8 triterpenoids, 3 alkaloids, 5 organic acids and 11 other components. Among them, 11 compounds were firstly found in A. cantoniensis Hance, and 9 compounds were confirmed by reference substance. CONCLUSIONS The analytical method based on UPLC-Q-TOF/MS combined with UNIFI platform can quickly identify the chemical constituents of A. cantoniensis Hance. Flavonoids and triterpenes are the main components in A. cantoniensis Hance.

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.
