Objective: To explore the determinants for health-seeking behavior of the residents after cough for more than 3 weeks in Yiwu, Zhejiang Province, in order to provide reference for prevention and control of respiratory diseases. Methods: A multi-stage cluster random sampling method was used to recruit the community residents aged 5 years and above in Yiwu. A face-to-face questionnaire survey was conducted to collect demographic information, features of cough and health-seeking behaviors in the past month. The multivariate logistic regression model was employed to analyze the associated factors for health-seeking behavior after a cough for more than 3 weeks. Results: Among 6 374 residents investigated, 152 cases had a cough for more than 3 weeks in the past month, accounting for 2.48%. They were( 45.00±21.15 ) years old, including 70 ( 46.05% ) males and 82 ( 53.95% ) females. About 58.55% ( 89 ) of them sought medical treatment. The results of multivariate logistic regression analysis showed that females ( OR=2.100, 95%CI: 1.005-4.391 ), middle school education level ( OR=0.406, 95%CI: 0.168-0.983 ), family annual income of 100 000 to 199 999 yuan ( OR=2.993, 95%CI: 1.215-7.373 ) were associated factors for health-seeking behavior after a cough for more than 3 weeks. Conclusion The rate of health-seeking behavior after a cough for more than 3 weeks among the residents in Yiwu is 58.55%, which is associated with gender, education level and income.

OBJECTIVETo investigate the coverage rate of primary immunization of measles containing vaccine (MCV1) among migrant children in Yiwu,Zhejiang province.

METHODSHousehold cluster sampling survey and probability proportion to size sampling method were adopted. A total of 967 migrant children born from 1st July 2007 to 1st July 2010 and their caregivers were selected as target population. Standard face-to-face interviews were conducted to investigate the subjects' knowledge, attitude, practice (KAP) of immunization, MCV1 vaccination and determinants. Multi-variable weighted average score method was adopted to evaluate the result of our survey on KAP. Kaplan-Meier analysis was adopted to assess the coverage of MCV1 and Cox regression analysis was adopted to explore the influencing factors associated with the coverage of MCV1.

RESULTSOut of the 967 children, 104 were born in 2007, accounting for 10.8%; 301 were born in 2008, accounting for 31.1%; 343 were born in 2009, accounting for 35.5% and 219 were born in 2010, accounting for 22.6%. Among the surveyed caregivers, 71.9% (695/967) were mothers and 90.2% (872/976) were migrant from other provinces. According to the result of survey on KAP among caregivers, 56.2% (543/967) scored ≥ 4 points on knowledge, 75.8% (734/967) scored ≥ 4 points on attitude and 48.7% (471/967) scored ≥ 4 points on behavior. 86.6% (838/967) of surveyed caregivers' education levels were under junior middle school.85.9% (831/967) of the migrant children were born in hospitals.36.3% (351/967) of the surveyed families' household income were under 2000 yuan per month.32.7% (316/967) of surveyed caregivers waited less than 15 min for immunization for each time. Coverage rate of MCV1 was 85.9% (831/967; 95%CI: 83.7%-88.1%). The timely coverage rates at 8 months, 12 months, and 24 months were 58.8% (569/967; 95%CI: 55.5%-62.1%), 88.2% (853/967; 95%CI: 86.0%-90.4%) and 98.6% (953/967; 95%CI: 97.8%-99.4%), respectively. The average age of MCV1 immunization for each birth cohort between 2007 and 2010 were 10.4, 10.1, 10.1 and 9.3 month, respectively; without statistical significance (χ(2) = 0.722, P = 0.398). According to the analysis by Cox regression, the caregivers aged ≤ 25 years (24.3% (235/967), RR = 1.520 (95%CI: 1.280-1.800)), the caregivers' education level above college (2.8% (27/967), RR = 3.841 (95%CI: 2.287-6.451)), delivered in county-level hospital (49.4% (478/967), RR = 6.048 (95%CI: 4.311-8.485)), household income > 4000 yuan per month (21.7% (210/967), RR = 1.366 (95%CI:1.163-1.604)), the average score of attitude towards immunization ≥ 4 points (75.9%(734/967), RR = 2.613 (95%CI: 1.026-6.655)), the average waiting time for each vaccination ≤ 15 min (32.7% (316/967), RR = 2.116 (95%CI: 1.341-3.339)) were the important factors to improve the timely immunization coverage rate of MCV1 among migrant children.

CONCLUSIONThe coverage of MCV1 were obviously delayed among migrant children in Yiwu, Zhejiang province. We suggest that the investigation of migrant children should be strengthened and remind or recall mechanism for immunization should be established. Increasing the open days for immunization clinics and reducing the waiting time for vaccination could also improve the coverage and timeliness of the MCV vaccination.

BACKGROUND: The tumor necrosis factor recepter associated factor (TRAF) 6 is an important intracellular adapter protein that plays a pivotal role in activating multiple inflammatory and immune related processes induced by cytokines. TRAF6 represents a strong candidate susceptibility factor for sepsis. We investigated whether polymorphisms at the TRAF6 gene are associated with the susceptibility to and severity of sepsis. METHODS: A hospital-based case-control study was conducted with 255 patients with sepsis and 260 controls who were recruited from Zhengzhou, China. Haplotype tagging single nucleotide polymorphisms (htSNPs) were selected from the HapMap database and genotyped using the SNPstream genotyping platform. The associations with the susceptibility and disease severity of sepsis were estimated by logistic regression, and adjusted for age, sex, smoking, drinking, chronic diseases status, APACHEII score and critical illness status. RESULTS: A total of 13 TRAF6 SNPs were tagged by 7 htSNPs. Five htSNPs (rs5030490, rs5030411, rs5030416, rs5030445 and rs3740961) were genotyped in the case control study. Genotype frequencies of the htSNPs were conformed to the Hardy-Weinberg equilibrium in both patients and controls. No significant association was found between the 5 htSNPs and the susceptibility to and severity of sepsis. Compared with the main haplotype -11120A/-10688T/-9423A/805G/12967G, no certain haplotype was associated with the significantly susceptibility to or severity of sepsis. CONCLUSION: TRAF6 gene polymorphisms might not play a major role in mediating the susceptibility to and severity of sepsis in the Chinese population. A larger population-based case-control study is warranted.

Purpose: Systemic inflammatory response is a critical factor that promotes the initiation and metastasis of malignancies including pancreatic cancer (PC). This study was designed to determine and compare the prognostic value of neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), monocyte-to-lymphocyte ratio (MLR), and fibrinogen-to-albumin ratio (FAR) in resectable PC and locally advanced or metastatic PC. Materials and Methods: Three hundred fifty-three patients with resectable PC and 807 patients with locally advan-ced or metastatic PC were recruited in this study. These patients were classified into a training set (n=758) and a validation set (n=402). Kaplan-Meier survival plots and Cox proportional hazards regression models were used to analyze prognosis. Results: Overall survival (OS) was significantly better for patients with resectable PC with low preoperative PLR (p=0.048) and MLR (p=0.027). Low FAR, MLR, NLR (p < 0.001), and PLR (p=0.003) were significantly associated with decreased risk of death for locally advanced or metastatic PC patients. FAR (hazard ratio [HR], 1.522; 95% confidential interval [CI], 1.261 to 1.837; p < 0.001) and MLR (HR, 1.248; 95% CI, 1.017 to 1.532; p=0.034) were independent prognostic factors for locally advanced or metastatic PC. Conclusion The prognostic roles of FAR, MLR, NLR, and PLR in resectable PC and locally advanced or metastatic PC were different. FAR showed the most prognostic power in locally advanced or metastatic PC. Low FAR was positively correlated with OS in locally advanced or metastatic PC, which could be used to predict the prognosis.
