Objective: To evaluate the relationship between IL-1 gene polymorphisms and coal workers’ pneumoconiosis and silicosis susceptibility. Methods: We searched published full-text from PubMed, Web of Science, CNKI, VIP and Wanfang to collect case-control study on IL-1 gene polymorphisms with coal workers’ pneumoconiosis and silicosis susceptibility. Eight articles, including 10 case-control studies were included in our study. All analyses were performed using the Stata version 12.0 software. Results: The IL-1RA (+2018) TC or CC variant genotypes were associated with coal workers’ pneumoconiosis and silicosis risk (OR=1.65, 95%CI: 1.11-2.46) . In further stratified analyses, the IL-1RA (+2018) TC or CC variant genotypes were associated with an increased silicosis risk (OR=2.07, 95%CI: 1.45-2.95) , which were also associated with increased coal workers’ pneumoconiosis and silicosis risk in Caucasians (OR=1.74, 95%CI: 1.22-2.47) . No significant association between IL-1β (+3953) , IL-1β (-511) , IL-1α (+4845) and coal workers' pneumoconiosis and silicosis risk was found either in the overall study or in the stratified analysis. Conclusion These findings suggested that IL-1RA (+2018) may modify coal workers’ pneumoconiosis and silicosis susceptibility. Further replication studies with large sample sizes are warranted to re-evaluate the relationship between IL-1RA (+2018) and coal workers’ pneumoconiosis and silicosis risk.

Objective To investigate the detection rates of cervical cancer and cervical precancerous lesions in rural women in Jiangsu province and to provide evidence for the prevention and treatment of cervical cancer.Methods According to the differences in economic geography,and the allocation of health resources,according to the project implementation status,data integrity and cervical cancer screening methods,two cancer screening program were randomly selected from rural women in Liuhe in south of Jiangsu,Qidong in center of Jiangsu,and Sihong in north of Jiangsu,the detection rate of cervical precancerous lesions,and the project of cervical cancer screeningdata were analyzed from 2014 to 2015.Results The average detection rate of cervical cancer among rural women in Jiangsu province from 2014 to 2015 was 35.23/10 million,the average detection rate of cervical precancerous lesions of 49.20/10 million.The detection rate of cervical carcinoma was the highest in Sihong(58.65/10 million),the minimum was six county (18.72/10 million),and cervical cancer detection rate was 26.02/10 million in Qidong.Conclusion The average detection rate of cervical cancer among rural women in Jiangsu province is higher than that of some provinces and cities,but is still lower than high incidence provinces.The detection rate of cervical cancer in Sihong county is relatively high,which may be related with underdeveloped economic in the region,and the spread of cervical cancer screening work is late and women~ health awareness is weak.

The etiology of pneumoconiosis is relatively clear, but the pathogenic mechanism is not fully understood, and there is no effective cure for pneumoconiosis. Clarifying the pathogenesis of pneumoconiosis and exploring relevant markers can help screen high-risk groups of dust exposure, and relevant markers can also be used as targets to intervene in the process of pulmonary fibrosis. The in-depth development of genomics, transcriptomics and proteomics has provided a new way to discover more potential markers of pneumoconiosis. In the future, the combination of multi-omics and multi-stage interactive analysis can systematically and comprehensively identify key genes (proteins) , metabolites and metabolic pathways in the occurrence and development of pneumoconiosis, build a core regulatory network, and then screen out sensitive markers related to early diagnosis and treatment of pneumoconiosis. This article summarizes the research progress of pneumoconiosis markers from the perspective of multi-omics, hoping to provide more basic data for the early prevention and diagnosis of pneumoconiosis, pathogenesis research, and therapeutic intervention.

Objective:Regulatory quantitative trait loci (regQTL) theory can help to evaluate the regulation function of single nucleotide polymorphisms (SNPs) on crucial biological signals from a three-dimensional perspective. The aim of this study was to investigate the effect of these regQTL-SNPs on the susceptibility of lung cancer.Methods:Based on the regQTL theory, using the database of identified lung cancer regQTL-SNPs, we screened the SNPs that may function as regQTL in the reported susceptible regions of lung cancer by genome-wide association study(GWAS), and a two-stage case-control study was conducted (screening stage: 2 331 lung cancer cases and 3 077 healthy controls; validation stage: 626 lung cancer cases and 667 healthy controls) to definite the association of related regQTL-SNPs with the susceptibility of lung cancer.Results:A total of 8 regQTL-SNPs were screened in the reported susceptible regions of lung cancer by GWAS. Among which, 3 SNPs were significantly associated with the risk of lung cancer ( P<0.05) in the screening stage. Further validation results indicated that the variant T allele of rs6998591 in ADRA1A was significantly associated with increased risk of lung cancer (additive model: OR=1.33, 95% CI:1.01-1.74, P=0.040). In addition, the variant G allele of rs11202916 in ACTA2 was significantly associated with decreased risk of lung cancer (recessive model: OR=0.71, 95% CI:0.52-0.96, P=0.026). Stratified analysis indicated that the variant T allele of rs6998591 significantly increased lung squamous cell carcinoma risk (additive model: OR=1.53, 95% CI: 1.01-2.32, P=0.043), while the variant G allele of rs11202916 significantly decreased lung adenocarcinoma risk (additive model: OR=0.83, 95% CI: 0.69-0.98, P=0.031). Gene-environment interaction analysis indicated that the risk of developing lung cancer increased by 235% in smoking individuals carrying rs6998591 variant T allele compared with those non-smoking individuals carrying no rs6998591 variant T allele( OR=3.35,95% CI:2.10-5.34, P<0.001). Conclusion:There are two regQTL-SNPs that could significantly affect the susceptibility of lung cancer in the GWAS reported susceptible regions of lung cancer.

Objective:Aanalysis the effect of booster one dose of hepatitis B vaccine after 21-32 years of primary immunization in Zhengding Country of Hebei Province.Methods:A total of 322 participants who were born between 1986 and 1996, received a full course of primary vaccination with plasma-derived hepatitis B vaccine (HepB), had no experience with booster vaccination, were HBsAg, anti-HBcnegative, had anti-HBs<10 mIU/ml, completed the booster and had laboratory results were enrolled between August 2017 to February 2018. A simple random method was uesd to randomly assigned 322 subjects to two groups, receiving a booster dose of HepB derived from either Saccharomyces cerevisiae ［HepB (SC), (151 cases)］ or Chinese hamster ovary-derived HepB ［HepB (CHO), (171 cases)］, the dose was 20 μg. Blood samples were collected 30 days after boosting and quantitatively tested for the geometric mean concentration (GMC) of anti-HBs to assess immunological effect. The related influencing factors of GMC and seroconversion rates of anti-HBs were analyzed by multiple linear regression and multivariate logistic regression models.Results:The 266 subjects (82.61%) had anti-HBs≥ 10 mIU/ml, and GMC was (131.63±12.94) mIU/ml.The seroconversion rates of anti-HBs in the anti-HBs<2.5 mIU/ml group and 2.5-10 mIU/ml group were 74.54% (161 cases) and 99.06% (105 cases), respectively ( P<0.001).The seroconversion rates of anti-HBs after one dose of HepB (CHO) was higher than that of one dose of HepB (SC), the seroconversion rates were 87.13% (149 cases) and 77.48% (117 cases), respectively ( P=0.023). Participants boostered with HepB (CHO) was the factor influencing the effect of strengthening immunization compared with boostered with HepB (SC), and OR (95% CI) was 1.91 (1.02-3.56) ( P=0.042).Compared with anti-HBs<2.5 mIU/ml, prebooster anti-HBs was between 2.5 mIU/ml and 10 mIU/ml was the related factor of seroconversion rates of anti-HBs after booster immunization, and OR (95% CI) was 36.15 (4.91-266.02) ( P<0.001). Conclusion:Participants boostered withone dose of HepB had a good immune response. Pre-booster anti-HBs concentration and a variety of vaccine were related factors of immune response.

BACKGROUND: Food safety and hygiene are currently a global health apprehension especially in unindustrialized countries as a result of increasing food-borne diseases (FBDs) and accompanying deaths. This study aimed at assessing knowledge, attitude, and hygiene practices (KAP) of food safety among street-cooked food handlers (SCFHs) in North Dayi District, Ghana. METHODS: This was a descriptive cross-sectional study conducted on 407 SCFHs in North Dayi District, Ghana. The World Health Organization's Five Keys to Safer Food for food handlers and a pretested structured questionnaire were adapted for data collection among stationary SCFHs along principal streets. Significant parameters such as educational status, average monthly income, registered SCFHs, and food safety training course were used in bivariate and multivariate logistic regression models to calculate the power of the relationships observed. RESULTS: The majority 84.3% of SCFHs were female and 56.0% had not attended a food safety training course. This study showed that 67.3%, 58.2%, and 62.9% of SCFHs had good levels of KAP of food safety, respectively. About 87.2% showed a good attitude of separating uncooked and prepared meal before storage. Good knowledge of food safety was 2 times higher among registered SCFHs compared to unregistered [cOR=1.64, p=0.032]. SCFHs with secondary education were 4 times good at hygiene practices of food safety likened to no education [aOR=4.06, p=0.003]. Above GHc1500 average monthly income earners were 5 times good at hygiene practices of food safety compared to below GHc500 [aOR=4.89, p=0.006]. Registered SCFHs were 8 times good at hygiene practice of food safety compared to unregistered [aOR=7.50, p<0.001]. The odd for good hygiene practice of food safety was 6 times found among SCFHs who had training on food safety courses likened to those who had not [aOR=5.97, p<0.001]. CONCLUSIONS Over half of the SCFHs had good levels of KAP of food safety. Registering as SCFH was significantly associated with good knowledge and hygiene practices of food safety. Therefore, our results may present an imperative foundation for design to increase food safety and hygiene practice in the district, region, and beyond.
