ABSTRACT
Objective: To understand the current situation of long working hours exposure of couriers in Zhejiang Province, and to analyze the influence of long working hours exposure levels on their occupational stress and depression symptoms, and provide a basis for promoting the physical and mental health of couriers. Methods: From September to December 2021 , 1159 couriers from Zhejiang Express Transport Companies were selected as respondents by cluster sampling, and their basic information were collected. The occupational stress and depression symptoms of the couriers were assessed using the Core Occupational Stress Scale (COSS) and the Patient Health Questionnaire-9 (PHQ-9). The effects of long work hours (>48 h per week) on the occupational stress and depression symptoms of the couriers were analyzed. Results: The average age of 1159 courier in Zhejiang Province was (33.24±8.42) years, the average weekly working hours were (63.21±18.77) h, and 75.15% (871/1159) were long-term workers. The detection rates of occupational stress and depression symptoms in courier were 32.44% (376/1159) and 32.53% (377/1159), respectively. There were significant differences in the detection rates of occupational stress and depression symptoms among couriers with different ages, educational background, marital status, monthly average income, length of service, position or post, shift status, drinking status, and average weekly working hours (P <0.05). The adjusted logistic regression analysis showed that, after adjusting for the influence of confounding factors such as age, educational background, marital status, monthly average income, length of service, position or post, shift status and drinking status, compared with the weekly working hours ≤48 h, weekly working hours of 63-77 h, 78-92 h, ≥93 h were the risk factors for occupational stress (OR=1.547, 95%CI: 1.019-2.350; OR=1.886, 95%CI: 1.184-3.006; OR=2.338, 95%CI: 1.188-4.062) and depression symptoms (OR=1.897, 95%CI: 1.258-2.860; OR=2.041, 95%CI: 1.290-3.230; OR=4.978, 95%CI: 2.551-9.715) of couriers (P<0.05) . Conclusion: Long working hours could increase the risk of occupational stress and depression symptoms among couriers. It is necessary to arrange working hours reasonably to reduce the occurrence of occupational stress and depression symptoms of couriers.

OBJECTIVE@#To compare the therapeutic effect on type 2 diabetes mellitus (T2DM) complicated with angina pectoris of coronary heart disease between the combined therapy of acupuncture and western medication and the simple administration of western medication.@*METHODS@#A total of 134 patients with T2DM and angina pectoris of coronary heart disease were randomly divided into two groups, i.e. an acupuncture plus medication group (67 cases, 3 cases dropped off) and a medication group (67 cases, 4 cases dropped off). The routine western medication was used according to symptoms in the patients of both groups. In the acupuncture plus medication group, on the base of medication, acupuncture was applied to Jianshi (PC 5), Quchi (LI 11), Neiguan (PC 6), etc. The needles were retained for 20 min in each treatment and 3 treatments of acupuncture were required weekly. The treatment was given consecutively for 8 weeks in the two groups. Separately, before and after treatment, the symptom scores of TCM were observed and the indexes were detected, including glycolipid metabolism [fasting plasma glucose (FPG), 2-h plasma glucose (2hPG), glucosylated hemoglobin (HbA1c), triacylglycerol (TG) and total cholesterol (TC)], islet β cell function [homeostasis model assessment-β (HOMA-β), homeostasis model assessment-IR (HOMA-IR), fasting insulin (FINS) and insulin sensitivity index (ISI)], cardiac function indexes [cardiac output (CO), early diastolic peak velocity/late diastolic peak velocity (E/A), left ventricular end diastolic diameter (LVEDD) and left ventricular ejection fraction (LVEF)], as well as electrocardiogram QT dispersion (QTd). Besides, the clinical therapeutic effects were compared between the two groups.@*RESULTS@#After treatment, the TCM symptom scores and the values of FPG, 2hPG, HbA1c, TG, TC, HOMA-IR, FINS, E/A and LVEDD as well as QTd were all lower than those before treatment in the two groups (@*CONCLUSION@#The combined therapy of acupuncture and medication is effective in treatment of T2DM complicated with angina pectoris of coronary heart disease. Such therapy effectively improves glucolipid metabolism, islet β cell function, cardiac function and myocardial blood supply. Its curative effect is better than the simple administration of western medicine.

ABSTRACT
The paper was aimed to investigate the association of VDR polymorphisms with tacrolimus (FK506) concentration in Chinese renal transplant recipients. A total of 114 renal transplant recipients receiving tacrolimus were genotyped for VDR rs1540339 and rs2853559 by Agena Bioscience MassARRAY® system and CYP3A5*3 by PCR-RFLP method. Trough concentrations of tacrolimus on day 7 after renal transplantation were collected from clinical data. Statistical analysis was performed with Spearman's correlation, Mann-Whitney U test and Kruskal-Wallis H test. The dose-adjusted concentration of tacrolimus in VDR rs2853559 GA and GG carriers were considerably higher than that of AA carriers. After stratification by CYP3A5*3 genotypes, VDR rs2853559 GA and GG carriers had a higher dose-adjusted tacrolimus concentration than that in AA carriers in CYP3A5 nonexpresser. CYP3A5*3 and VDR rs2853559 explained 45.6% variability of tacrolimus C0/D. In CYP3A5 non-expressers, VDR rs2853559 explained 14.4% variability of tacrolimus C0/D. The results illustrated that VDR rs2853559 polymorphisms was associated with tacrolimus concentrations, and the determination of this SNP may be useful for individualized medicine of tacrolimus.

ABSTRACT
This study aims to investigate the function of two SNPs (rs8904C > T and rs696G > A) in 3' untranslated region (3'UTR) of NFKBIA gene by constructing luciferase reporter gene. A patient's genomic DNA with rs8904 CC and rs696 GA genotype was used as the PCR template. Full-length 3'UTR of NFKBIA gene was amplified by different primers. After sequencing validation, these fragments were inserted to the luciferase reporter vector, pGL3-promoter to construct recombinant plasmids containing four kinds of haplotypes, pGL3-rs8904C/rs696G, pGL3-rs8904C/rs696A, pGL3-rs8904T/rs696G and pGL3-rs8904T/rs696A. Then these plasmids were transfected into LS174T cells and the luciferase activity was detected. Compared with pGL3- vector transfected cells (negative control), the luciferase activity of the four kinds of recombinant plasmids was significantly decreased (P A, the luciferase activity of the recombinant plasmids containing A allele (pGL3-rs8904C/rs696A and pGL3-rs8904T/rs696A) was about 45.1% (P P T, there were no significant differences in the luciferase activity between the recombinant plasmids containing T allele and those with C allele. Together, the luciferase reporter gene vectors containing SNPs in NFKBIA gene 3'UTR were constructed successfully and rs696G > A could decrease the luciferase activity while rs8904C > T didn't have much effect on the luciferase activity.
ABSTRACT
OBJECTIVE: To investigate the occupational stress level and its influencing factors among employees in a power supply enterprise. METHODS: By cluster stratified random sampling method,251 workers in a power supply enterprise were selected as study subjects. The Simple Occupational Stress Questionnaire and the Chinese version of Effort-Reward Imbalance( ERI) Questionnaire were used to investigate and evaluate their job demand-control( JDC) and ERI occupational stress situation respectively. The related influencing factors were analyzed. RESULTS: Among the 251 workers,the positive rates of JDC high occupational stress and ERI high occupational stress were 74. 5%( 187 /251) and 22. 7%( 57 /251),respectively. The positive rate of JDC high occupational stress was higher than that of ERI occupational stress( P < 0. 01). The multivariate logistic analysis results indicated the risk of JDC high occupational stress in married workers was higher than that in single workers( P < 0. 05),workers with day-time working > 8 hours had higher risk of JDC high occupational stress than those workers with day-time working ≤8 hours( P < 0. 05). The male workers had higher risk of ERI high occupational stress than female workers( P < 0. 05). CONCLUSION: The main occupational stress model of workers in the power supply enterprise is the JDC model. The main influencing factors were marital status,day-time working hours and gender.
ABSTRACT
This study proposes a new framework as job burden-capital model for comprehensive assessment on occupational stress. 1618 valid samples were recruited from electronic manufacturing service industry in Hunan province by self-rated questionnaires after written consent. Structural equation model analysis was employed to verify the model by the data collected. The final fitting model has satisfactory fitting goodness (CMIN/DF=5.78, AGFI=0.937, NNFI=0.960, IFI=0.968, RMSEA=0.054). Both of the measurement model and structural model have acceptable path loadings. Job burden and capital could either directly affect occupational outcomes or indirectly influence them through personality. Multi-group structural equation model analyses indicate general applicability of the model to the basic features of such population. The job burden-capital model opens up new horizons for more in-depth study on occupational stress.

The study aims to investigate the associations of SUMO4 polymorphisms with tacrolimus concentrations in Chinese renal transplant recipients. Blood samples and clinical data were collected from 132 renal transplant recipients with tacrolimus treatment. CYP3A5*3 genotypes were detected by PCR-RFLP, and SUMO4 (rs237024, rs237025) genotypes were detected by Sequenom® MassARRAY system. SUMO4 rs237024 and rs237025 genotypes were in complete linkage disequilibrium (D' = 1). The dose-adjusted concentration of tacrolimus in SUMO4 rs237024A-rs237025A (GA-GA +AA-AA) carriers was considerably higher than that in GG-GG carriers (P < 0.05). After stratification by CYP3A5*3 genotypes, SUMO4 rs237024A-rs237025A carriers (GA-GA+AA-AA) had a higher dose-adjusted tacrolimus concentration than that in GG carriers in CYP3A5 expresser (P < 0.05). The results illustrated that SUMO4 rs237024 and rs237025 polymorphisms were associated with tacrolimus concentrations, and the test of these genotypes may be useful for individualized medicine of tacrolimus.
