Objective To explore the role of microRNA-145-5p(miR-145-5p)in the regulation of inflammatory response and oxidative stress process in cellular model of atherosclerosis.Methods Human monocytic leukemia THP-1 cells-derived foam cells were constructed in vitro.Then,the relative expression of miR-145-5p in the model and control groups of cells were detected by qRT-PCR.TargetScan database was used to predict the targeting relationship between miR-145-5p and Toll-like receptor 4(TLR4).The 293T cells were divided into wild-type+mimic group,wild-type+mimic negative control(NC)group,and mutant+mimic group,mutant+mimic NC group,and dual luciferase assay was employed to verify the targeting relationship of miR-145-5p and TLR4.Foam cells were cultured in vitro and divided into miR-145-5p mimic group,mimic NC group,miR-145-5p inhibitor group,and inhibitor NC group according to the corresponding treat-ments.The expression of TLR4 at mRNA and protein levels was detected by qRT-PCR and Wes-tern blotting.The contents of TNF-α,IL-1β and IL-6 were detected by ELISA.Biochemical reagent kits were applied for generation of reactive oxygen species(ROS),content of MDA and activity of SOD.Results The expression of miR-145-5p was significantly reduced in the model group than the control group(0.29±0.01 vs 1.00±0.08,t=11.180,P<0.01).Dual luciferase assay showed that luciferase activity was significantly lower in the miR-145-5p mimic group than the mimic NC group(t=8.612,P<0.01).Compared with the mimic NC group,the mimic group had obviously lower mRNA and protein levels of TLR4 and contents of TNF-α,IL-1β,lL-6,ROS and MDA,and higher miR-145-5p expression level and SOD activity(P<0.05,P<0.01).The treatment of inhibi-tor resulted in increased TLR4 mRNA and protein levels and TNF-α,IL-1β,IL-6,ROS and MDA contents,and decreased miR-145-5p expression and SOD activity when compared with the above levels in the inhibitor NC group(P<0.05,P<0.01).Conclusion MiR-145-5p inhibits inflamma-tion and oxidative stress in cellular model of atherosclerosis by targeting TLR4.

OBJECTIVETo investigate the association between programmed death 1 (PDCD1) gene polymorphism and dilated cardiomyopathy (DCM).
METHODSTwo single nucleotide polymorphisms (SNPs) of the PDCD1 gene, rs2227981, rs2227982, were genotyped and detected in 340 DCM patients and 401 healthy controls using the method of polymerase chain reaction-restriction fragment length polymorphism (PCRRFLP). The genotype frequencies and allele frequencies of SNPs were compared between DCM patients and normal controls.
RESULTSThe genotype and allele distributions of rs2227982 were significantly different between the patients with DCM and the controls. The frequencies of TT genotype and T allele of rs2227982 were higher in the patients than those in the controls (35.3% vs. 23.4%, P < 0.01, OR=2.37, 95%CI: 1.57-3.57; 58.5% vs. 47.4%, P < 0.01, OR=1.58, 95%CI: 1.28-1.93, respectively). No association was observed for rs2227981 between the DCM patients and the controls.
CONCLUSIONrs2227982 in PDCD1 gene is association with DCM in Chinese Han population, which supported PDCD1 as a susceptibility gene for DCM. TT genotypes and T allele in rs2227982 may be associated with significantly increased risk of DCM.

Objective:Applying bibliometrics to analyze the research history, hotspots and trends of Traditional Chinese Medicine (TCM) interventions in edema-related diseases, and to provide reference for the revision of diagnostic and therapeutic criteria for edema in TCM.Methods:The literature about edema treated with TCM was retrieved from CNKI, Wanfang, VIP, CBM from 1 st. Jan 1995 to 25 th. May 2022. CiteSpace and VOSviewer softwares were used to draw the knowledge map, and analyze the co-occurrence relationship and clustering characteristics of the institution, author, keywords and mechanism hotspots. Results:Totally 3 198 articles were included. The annual number of documents issued generally shows a spiral rise trend. Liaoning University of Chinese Medicine published the most articles. Core authors published the most articles were Sun Wei (13 articles); the team with the highest cooperation intensity was Yang Hongtao's team; keywords formed 7 clusters. Hotspot mechanisms included metabolic disorders, immune balance, anti-inflammation, calcium and phosphorus metabolism. Keywords in the past 7 years were membranous nephropathy, chronic heart failure, diabetes, lymphedema etc.Conclusions:The attention paid to the intervention of TCM in the field of edema is generally on the rise, and has decreased in the past two years. The research categories focus on the experience of famous doctors, clinical trials, and mechanistic studies, and nephropathy-related edema has been the focus of research; diabetic nephropathy, chronic heart failure, metabolomics, and immunotherapy are expected to be the focus of attention in the next stage.

Patients with bicuspid aortic valve are often complicated with aortic dilatation. If the aortic valve is of good quality, aortic root replacement with aortic valve preservation is feasible. A 35-year-old male patient with bicuspid aortic regurgitation complicated with ascending aortic aneurysm underwent Remodeling+Ring (modified Yacoub) operation. Echocardiography showed that there was no aortic regurgitation on the 3rd day after operation, and the patient was discharged satisfactorily on the 6th day after operation. Remodeling+Ring surgery ensures the physiological movement of the aortic valve, solves the enlarged annulus, avoids the problems caused by valve replacement, and significantly improves the quality of life of patients, which is worth popularizing.

Objective:To analyze the efficacy evaluation criteria of the existing TCM treatment for edema RCT research, and to provide reference for the construction of unified standards.Methods:The batabases CNKI, WanFang Data, VIP, CBM, Pubmed and Web of Science were retrieved. The randomized controlled trials for the treatment of edema of TCM research, from September 1, 1993 to July 31, 2022, were screened and included. The content of efficacy evaluation, performed statistics on evaluation standard, the curative effect evaluation indexes, as well as standard composition, usage were extracted. We analyzed the characteristics, application and problems of the existing efficacy evaluation criterion.Results:A total of 123 Chinese articles were included. The included literature involved nephrogenic edema, cardiogenic edema, idiopathic edema, apoplexy limb edema and other edema. In recent years, randomized controlled trials on the treatment of edema by TCM have mainly used four efficacy evaluation criteria. Of which the Guidelines for Clinical Research on New Chinese Medicines (Trial) in 2002 had the highest utilization rate of 29.27%. Secondly, the utilization rate of Standard for Diagnosis and Curative Effect of TCM Diseases and Syndromes was 21.14%. The rest of the criteria were used by less than 6%. While 39.02% of the literature did not use the standards or used self-designed standards. Among the composition of efficacy evaluation indices, the application rate of TCM syndrome or symptom efficacy index was the highest (91.87%), the utilization rate of the Minnesota Living with Heart Failure Questionnaire Indicators was only 4.88%; biochemical tests accounted for a large proportion of Western medical indicators, while the measurement of edema severity was rarely applied. Conclusions:At present, the evaluation criteria of edema curative effect are diversified and insufficiently popularized, which need to be further screened and improved. It is suggested to construct a TCM edema efficacy evaluation model based on the characteristics of edema syndrome, comprehensively evaluate the efficacy from multiple dimensions such as TCM syndromes, western medicine indicators, and quality of life, and improve the scientific indicators.

BACKGROUND:
Most Chinese migrants have been faced with obstacles to getting access to local public health services. Young migrants among internal migrants make a major contribution to the economy. However, the establishment of their health records has been ignored. This research was aimed at exploring the status and associated factors of the establishment of health records among young Chinese migrants.
METHODS:
Data were obtained from the 2017 China Migrants Dynamic Survey (CMDS). Chi-square test and binary logistic regression were performed to investigate the associated factors of the establishment of health records among young Chinese migrants.
RESULTS:
Approximately 30.2% of young migrants had their health records established in inflow communities. Urban residence, medical insurance (insured), and lower average monthly household income were attributed to the establishment of more health records. Young migrants who were in northeast China and across provinces and immigrated for working or engaging in trade were less likely to have health records established. Young migrants who participated in social activities and public affairs activities and took type of people in touch as natives in the inflow area showed a higher possibility of establishing health records. Meanwhile, receiving health education and hearing about national basic public health services (BPHSs) were beneficial for establishing the health records of more young migrants.
CONCLUSION
This study showed that the health records of young migrants had a relatively low establishment rate. Sociodemographic and migration characteristics, health status, public health services, and social integration factors were all related to the health record establishment of young Chinese migrants.

Five new terpenoids, including two vibsane-type diterpenoids (1, 2) and three iridoid allosides (3-5), together with eight known ones, were isolated from the leaves and twigs of Viburnum odoratissimum var.sessiliflorum. Their planar structures and relative configurations were determined by spectroscopic methods, especially 2D NMR techniques. The sugar moieties of the iridoids were confirmed as β-D-allose by GC analysis after acid hydrolysis and acetylation. The absolute configurations of neovibsanin Q (1) and dehydrovibsanol B (2) were determined by quantum chemical calculation of their theoretical electronic circular dichroism (ECD) spectra and Rh2(OCOCF3)4-induced ECD analysis. The anti-inflammatory activities of compounds 1, 3, 4, and 5 were evaluated using an LPS-induced RAW264.7 cell model. Compounds 3suppressed the release of NO in a dose-dependent manner, with an IC50 value of 55.64 μmol·L-1. The cytotoxicities of compounds 1-5 on HCT-116 cells were assessed and the results showed that compounds 2 and 3 exhibited moderate inhibitory activities with IC50 values of 13.8 and 12.3 μmol·L-1, respectively.

BACKGROUND:
Limited published research has examined the relationships of negative life events and coping styles with sleep quality in Chinese junior high school students. We aimed to investigate the prevalence of poor sleep quality and to clarify the role of coping styles between negative life events and sleep quality.
METHODS:
A cross-sectional study of 3081 students was conducted in Ganzhou City, Jiangxi Province, Southeastern China. Adolescent Self-Rating Life Events Checklist, Simplified Coping Style Questionnaire, and Pittsburg Sleep Quality Index were applied to assess negative life events, coping styles, and sleep quality, respectively. Descriptive analyses, independent-samples t tests, one-way analyses of variance, Pearson correlation analyses, and structural equation modeling (SEM) were applied to analyze the data.
RESULTS:
The prevalence of poor sleep quality was 26.7%. Negative life events (B = 0.038, P < 0.001) and negative coping style (B = 0.049, P < 0.001) demonstrated a positive association with poor sleep quality, while positive coping style indicated a negative association with poor sleep quality (B = -0.029, P < 0.001). Interactions of negative life events and coping styles with sleep quality were not found (all P > 0.05). The association between negative life events and sleep quality was mediated by negative coping styles.
CONCLUSIONS
Our results indicated that poor sleep quality was common in these Chinese adolescents. Negative life events and negative coping style were associated with an increased prevalence of poor sleep quality, while the positive coping style was related to a decreased prevalence of poor sleep quality. A negative coping style mediated the association between negative life events and sleep quality.

ObjectiveTo investigate the characteristics of serum perfluoroalkyl substances (PFASs) exposure and potential influencing factors among community residents in Songjiang District, Shanghai. MethodsIn August 2021, residents who underwent routine health checkups in a community in Songjiang District, Shanghai were recruited as study subjects. The inclusion criteria were adult residents who had lived in the area for more than 3 years, had no occupational exposure history, no underlying diseases, were not pregnant, and were able to complete the questionnaire independently and sign the informed consent form. A questionnaire survey was conducted and venous blood samples were collected. The concentrations of 15 PFASs in serum were determined using ultra-high performance liquid chromatography-tandem quadrupole mass spectrometry (UPLC-MS/MS). Ordered multi-class logistic regression, interquartile range (IQR), and odds ratio (OR) were used to explore the influencing factors and risk magnitude of serum PFASs concentrations. ResultsOf the 15 PFASs, 14 were detected, and the detection rates of 7 PFASs were higher than 50%. The highest detected concentrations among the PFASs were PFOS (perfluorooctane sulfonate), PFOA (perfluorooctanoic acid), and PFHxS (perfluorohexane sulfonate), with median concentrations of 48.61 μg∙L-1, 37.29 μg∙L-1, and 36.51 μg∙L-1, respectively. The strongest correlation was between PFDA and PFUnDA (r=0.93, P<0.05), followed by PFOS and PFDA (r=0.86, P<0.05). Age, frequency of plastic product use, time spent indoors per day, personal annual income, tea consumption, and daily water intake were potential factors for exposure to PFASs. Among them, age was positively correlated with PFASs; tea consumption was positively correlated with PFNA and PFOA; PFHpA was negatively correlated with the frequency of plastic product use and personal annual income; and PFOS was negatively correlated with the time spent indoors per day. ConclusionThe exposure to serum PFASs among community residents in Songjiang District was relatively serious, and the main components were traditional PFOA, PFOS, and PFHx. Different sociodemographic characteristics had varying degrees of influence on the concentrations of PFASs in serum. The impact of PFASs exposure on the health of community residents deserves further investigation.

OBJECTIVE: To explore the effect of occupational high temperature exposure on type 2 diabetes( T2 DM) in male steel workers. METHODS: A cluster random sampling method was used to select 684 male steel workers,who exposed to occupational high temperature in a steel enterprise in Tangshan City,as the high temperature group,and 1 153 male steel workers without occupational high temperature exposure as the control group. The high temperature level of workers in these two groups was measured. The cumulative exposure( CE) of high temperature was calculated,and occupational health exam was performed. The multivariate logistic regression analysis and restricted cubic splines were used to analyze the relationship between high temperature CE and T2 DM. RESULTS: The prevalence of T2 DM in high-temperature group was higher than that in the control group( 13. 0% vs 7. 9%,P < 0. 05). The multivariate logistic regression analysis results showed that the risk of T2 DM in the high temperature group was higher than that in the control group after adjusting for age,body mass index,smoking,drinking,physical exercise and parents with diabetes( P < 0. 05). The 95% confidence interval was 1. 65( 1. 17-2. 33). Restricted cubic spline analysis showed that the high temperature CE was correlated with the prevalence of T2 DM in workers( P < 0. 01) and showed a linear correlation( nonlinearity test,P > 0. 05). CONCLUSION: Occupational high temperature exposure is associated with the occurrence of T2 DM in male steel workers. The male steel workers with high temperature CE show high prevalence of T2 DM risk.
