Abstract:
Objective To investigate whether elevated level of high sensitivity C-reactive protein (hsCRP) at baseline is associated with an increased risk of upper gastrointestinal cancer among smokers in Kailuan cohort. Methods Levels of hsCRP were tested and demographic information and risk factor data were collected at baseline for all subjects (2006-2007). Multivariable Cox proportional hazards regression models were used to analyze the association between baseline levels of hsCRP and upper gastrointestinal cancer. Results A total of 38 549 smokers from the Chinese Kailuan cohort were enrolled in the study in July 2006. Median follow-up time was 8.1 years. A total of 123 new upper gastrointestinal cancer cases were diagnosed and were divided into three groups according to the level of hsCRP (<1 mg/L,1-3 mg/L and >3 mg/L). The eight years cumulative incidence of upper gastrointestinal cancer was 278/100 000, 339/100 000 and 484/100 000 in these 3 groups, respectively ((口恶)2=6.48,P=0.039). Compared to smokers with lower hsCRP levels (<1 mg/L), smokers with the highest hsCRP levels (>3 mg/L) had significantly increased risk of upper gastrointestinal cancer (HR=1.64, 95% CI:1.05-2.56, P=0.028) after adjusting for gender, age, drinking, BMI, diabetes, work environment and education degree. Compared to smokers with lower hsCRP levels (<1 mg/L), smokers with the highest hsCRP levels (>3 mg/L) had significantly increased risk of upper gastrointestinal cancer (HR=1.71, 95% CI:1.08-2.70, P=0.022) in the population of smokers aged 45 years old and above. Conclusions Elevated levels of hsCRP at baseline might increase the risk of upper gastrointestinal cancer in smokers.

Abstract:
Objective To assess the effectiveness of dietary inflammatory index (DⅡ) in pregnant women and the association between DⅡ and serum high-sensitivity C-reactive protein (hs-CRP) in the second trimester of pregnancy and the risk of gestational diabetes mellitus (GDM). Methods A prospective cohort study was conducted at the First Affiliated Hospital of Anhui Medical University for pregnant women. A total of 336 women with singleton pregnancy and without obvious symptoms of infection in 16-20 gestational weeks were enrolled in the study. DⅡ and serum hs-CRP concentration were measured in 16-20 gestational weeks. DⅡ was derived from individual dietary intake obtained by 3 consecutive 24-hour recalls using a validated algorithm. The participants were followed up until delivery and the pregnancy outcomes were recorded. Results A total of 110 observations (32.74% of the total 336 observations) had elevated hs-CRP (>3 mg/L). The risk of developing GDM among women in the elevated hs-CRP compared with the normal hs-CRP was 1.96(95% CI:1.03-3.75). The significant positive relationship was showed between DⅡ and hs-CRP during the second trimester of pregnancy (r=0.20,P=0.003). Three groups were divided according to tertiles of DⅡ. The lowest (most anti-inflammtory) tertile was the referent. The risk of developing GDM increased across the tertiles (i.e., with increasing inflammatory potential):odds ratio (tertile2)=3.66 (95% CI:1.11-12.12); odds ratio (tertile3)=5.99 (95% CI:1.85-19.41). Conclusions The DⅡ is a novel tool that characterizes the inflammatory potential of diet for pregnant women. A higher DⅡ is prospectively associated with a higher risk of GDM, with association with serum hs-CRP. Promotion of a healthy diet exhibiting anti-inflammatory properties may contribute to prevent GDM.

Abstract:
Objective To explore the epidemiological characteristics of elderly unintentional fall-related injuries (EUFI) in Guangzhou and to provide evidence for scientific preventive strategies of EUFI. Methods Data on EUFI was collected from the first diagnosed cases in the injury surveillance hospitals in Guangzhou from 2014 to 2016 and demographic and characteristics of injuries were analyzed. Spearman's correlation was used to examine the associations between daily meteorological factors and the number of cases of EUFI. Logistic regression was performed to identify the risk factors for EUFI. Results A total of 4 451 EUFI cases were reported in Guangzhou from 2014 to 2016, accounting for 50.80% of all unintentional injuries in the elderly, with the sex ratio of male to female 1:1.67. Most EUFI occurred in autumn (27.68%). The most common place where falls occurred was at home (73.58%). The common injuries caused by fall were bruise (48.51%) and fractures (30.67%) respectively. Most of fall injuries were mild (62.39%). Daily wind speed, pressure and rainfall were positively correlated with the number of daily EUFI cases, while daily average temperature and sunshine hours were negatively correlated with daily EUFI (all P<0.05). The risk factors of EUFI were female, aged ≥ 70 years, immigrants, and cold temperature (all P<0.05). Conclusions Fall is the main cause of unintentional injuries in the elderly in Guangzhou. Cold temperature has adverse impact on EUFI, while the older women and immigrants are high-risk population. It is important to take targeted preventive measures and intervention to avoid EUFI.

Abstract:
Objective To establish a predictive model of fall injury of minors in urban and rural areas in Jiangsu Province, and predict the occurrence of fall injury in urban and rural areas in order to offer reference of preventing and controlling minors fall injury. Methods The minors fall cases of urban and rural areas in Jiangsu Province from 2006 to 2014 were collected and grouped by monthly occurrence. The data from 2006 to 2013 was used as the fitting samples, and the data for 2014 was used as the forecast samples. The seasonal autoregressive integrated moving average model (SARIMA model) was established and analyzed by statistical software SPSS 18.0. Results Through the process of modeling, the ultimately fitting model was SARIMA(0,1,1) (0,1,1)12 and SARIMA(0,1,1) (1,1,0)12 for urban and rural areas, respectively. The model diagnosis showed the residual error was white noise, and the Box-Ljung test for the model showed Q statistic was not statistically significant, so the model fitted the data well. In 2014, the average relative error between predicted value and observed value was 11.89% in urban, the corresponding average relative error in rural was 2.10%. The predicted results of the two places were nearly in accordance with the observations. Conclusions SARIMA model could forecast accurately for the falls of minors cases in Jiangsu Province, thus it can provide reliable data base in order to prevent and control cases of fall injury of minors more timely and scientifically.

Abstract:
Objective To investigate the interactions among factors influencing the fracture of hospitalized children in Hunan province, so as to provide targeted measures for the prevention of pediatric fractures. Methods The interactions among factors influencing children's fracture were screened and analyzed by the log linear model. Results There were significant difference in the cure rate ((口恶)2=51.036, P<0.001),the duration of hospital stay (H=67.101,P<0.001) and the hospitalization expenses (H=46.282,P<0.001) of different types of fracture of hospitalized children. There were interactions between the causes of fracture and types of fracture.The fall injury was easy to cause the fracture of the ulna or radius, and the traffic accident was prone to the fracture of the tibia or fibula. There were interactions among gender, age and causes of fracture.The most common causes of fracture among 0 to 3 years old boys were traffic accidents and falls. There were interactions among gender, age, and types of fracture. 0 to3 years old children, regardless of the gender, were less inclined to the fracture of ulna, radius or humerus. Conclusions Targeted measures should be taken to prevent children from fracture according to the age, gender, causes of fracture and types of fracture.The log-linear model can be used to analyze the interactions among multiple variables, and it is suitable for exploratory research.

Abstract:
Objective To explore the genetic polymorphisms of interleukin-17 (IL-17), toll-like receptors 4 (TLR4) and purnergic receptor P2X7 (P2X7) in association with the chronic obstructive pulmonary disease (COPD). Methods A case-control study was performed by recruiting 152 COPD cases from the Third People's Hospital of Nantong from June 2015 to May 2016. Healthy controls were selected from a group of people attending the physical examination and were frequency-matched to the cases by sex and age. Genotyping was performed by using the TaqMan allelic discrimination technology. The association was estimated by using odds ratio (OR) and 95% confidence interval (CI). Results After the Bonferroni correction, the polymorphisms of rs2275913 and rs763780 in IL-17 gene, rs10759932 and rs2737190 in TLR4 gene, and rs1718119 in P2X7 gene were significantly associated with the altered risks of COPD (all P<0.05). Individuals carrying rs2275913 allele A had a reduced risk of COPD, with the OR of 0.62(95% CI:0.46-0.86). Individuals carrying rs763780 allele C had an increased risk, with the OR of 1.96(95% CI:1.29-2.98). Individuals carrying rs10759932 allele C had a reduced risk, with the OR of 0.49(95% CI:0.34-0.73). Individuals carrying rs2737190 allele G had a reduced risk, with the OR of 0.51(95% CI:0.37-0.71). Conclusions Genetic polymorphisms of IL-17, TLR4 and P2X7 were significantly associated with the altered risks of COPD.

Abstract:
Objective To analyze the characteristics of rpoB gene mutation in rifampicin-resistant mycobacterium tuberculosis isolate from Yunnan province. Methods This study selected 102 mycobacterium tuberculosis isolates and 1 strain of H37Rv standard mycobacterium tuberculosis. The fragments of rpoB gene including rifampicin resistance determining region were amplified by polymerase chain reaction (PCR), followed by sequencing. Results were analyzed by MEGA 5 software. Results The coincidence rate of rifampicin-resistant genotype and phenotype was 92.00%(69/75). There were 11 species of mutations which affect amino acid sequence. All mutations were point mutations, among which, 92.96% were single codon mutations and 7.04% were combination mutations. The top 3 codon mutations were rpoB531 (43.66%), rpoB526 (26.76%) and rpoB516 (9.86%), accounting for 80.28% of all mutations tested. There was no difference in rpoB gene mutations in clinical isolates from new patients and retreatment patients. There was a difference in the composition of rpoB mutations in MDR-TB and rifampicin resistant. Conclusions The detection of rpoB mutations in Yunnan Province can be used as an important indicator for rifampicin-resistant screening. The rpoB gene mutations may not be affected by previous administration of rifampicin and the duration of administration, while isoniazid may affect the molecular mechanism of rpoB gene mutations in Mycobacterium tuberculosis.

Abstract:
Objective To explore the relationship of plasma interleukin 6(IL-6) concentration with HCV RNA, liver function in hepatitis C patients and investigate the role of cytokines in chronic HCV infection. Methods 138 patients with persistent HCV infection and 152 uninfected controls were selected in this study. The plasma IL-6 level and HCV viral load were detected by enzyme linked immunosorbent assay (ELISA) and fluorescence quantitative polymerase chain reaction (FQ-PCR) respectively. The spearman correlation and partial correlation analyses were used to explore their correlations with liver function indexes. Results The chronic HCV infected patients had higher plasma IL-6 level than that of healthy controls (t=-3.066, P=0.002). The IL-6 concentration had a positive correlation with alanine aminotransferase (ALT), aspartate aminotransferase (AST) (before the adjustment:rALT=0.186, PALT=0.001, rAST=0.177. PAST=0.003; after the adjustment:rALT=0.200, PALT=0.001, rAST=0.127, PAST=0.039). The HCV viral load was positively correlated with the IL-6 level in chronic hepatitis C patients (before the adjustment:r=0.199, P=0.019; after the adjustment:r=0.200, P=0.025). Conclusions The plasma IL-6 may be associated with HCV infection and chronic level. The findings provided more insights into the immune mechanism for the development of HCV infection.

Abstract:
Objective To investigate the self-rated health status and influencing factors among the elderly in Jianyang City. Methods Based on the household health survey in 2015, the elderly aged 60 years and over were included in the analysis. Multi-level logistic model based on the level of town, family and individual was applied to examine the factors influencing the elderly's self-rated health. Results Among the 6 525 old people included in the study, 2 013(30.9%) individual evaluated their health status as good, 3 389(51.9%) as general, 1 123(17.2%) as poor. Multilevel model indicated that the self-rated health clustered in town and family level. Age, education, marriage, chronic disease, reporting illness within 2 weeks, depression, smoking, drinking, acquiring health knowledge, utilization of preventive service, family relationship and living condition were influencing factors of self-rated health in old people. Conclusions The self-evaluated health is affected by various factors.More attention should be paid to the elderly with low education level, poor living condition, poor health situation, lack of health care awareness, weak social support and depression. Comprehensive interventions on the level of region, family and individual should be considered to promote the health condition of the elderly.

Abstract:
Objective To study the risk factors of severe early childhood caries (SECC) among 5 years old children in Guangzhou, and to provide theoretical evidence for developing scientific and effective interventions. Methods 1:1 matched case-control study was conducted in 244 cases with SECC and 244 controls with no caries based on population survey. Univariate and multivariate conditional Logistic regressions were used to analyze the factors influencing SECC. Results Multivariate conditional Logistic regression showed that low birth weight (OR=3.08, 95% CI:1.00-9.43, P=0.049), high birth weight (OR=2.30,95%CI:1.06-4.97,P=0.035) regular eating sweets (OR=2.17, 95% CI:1.07-4.44, P=0.033), habit of eating sweets before bedtime (OR=1.80, 95% CI:1.08-2.98, P=0.023), parent age (OR=0.05, 95% CI:0.28-0.87, P=0.015) were risk factors for the occurrence of SECC among 5 years old children in Guangzhou. Conclusions Parents should pay more attention to children's deciduous caries, and good eating habits should be developed from younger age for reducing SECC occurrence.

Abstract:
Objective To assess early neurodevelopment of premature infants and explore its influencing factors and provide guidance on health care for premature infants. Methods A total of 859 premature infants were followed up and given early comprehensive intervention. Bayley scales of infant development (BSID-I) was used to evaluate their mental and motor development. Multivariable linear regression analysis was used to explore influencing factors of mental and motor development. Results At the corrected age of 6 months, the growth retardation rate of mental and motor development was 2.4% and 3.4%, respectively. Premature infants with birth weight ≥ 2 000 g, monthly household income ≥ 5 000 yuan and breast-feeding within the first 6 months had better mental development (all P<0.05); and those with monthly household income ≥ 5 000 yuan, breast-feeding within the first 6 months and with completed early family intervention had better motor development (all P<0.05). Multivariable linear regression analysis showed that mental development was positively correlated with breast-feeding within the first 6 months (β=2.827, 95% CI:0.348-5.305), higher birth weight (β=4.030, 95% CI:1.351-6.710) and higher monthly household income (β=2.909, 95% CI:0.352-5.465);and mental development was positively correlated with completed early family intervention (β=2.331, 95% CI:0.146-4.516) and higher monthly household income (β=2.848, 95% CI:0.156-5.541). Conclusions Breast-feeding within 6 months and early family intervention could promote neurodevelopment of premature infants. Thus, more attention should be paid to premature infants with lower birth weight and lower household income.

Abstract:
Objective To investigate the prevalence and clinical characteristics of epstein-barr (EB) virus infection in the hospital and to provide scientific theoretical basis for the prevention and treatment of EBV infection and related diseases. Methods A retrospective study was conducted among EB infected patients in our hospital from October 2015 to September 2016. The relationship between detection results and clinical data of patients were analyzed. Results The plasma samples from 1 313 patients were collected and detected for EB infection. 314 cases were found EBV-DNA positive with a total positive rate of 23.91%. The positive rates of female patients (21.60%) and male patients (25.27%) showed no significant difference ((口恶)2=2.26, P=0.133). The positive rate of EBV-DNA varied in different age groups, peaking at 1-10 and 61-70 years old. The positive rate altered by different seasons was highest (36.44%) in autumn and lowest in winter (13.00%). There was significant difference in the EB infection rate among different departments of the hospital. The top five departments with high infection rate of EB were pediatrics (40.91%), radiotherapy (39.30%), hematology (18.50%), infectious disease (16.98%) and intensive care unit (15.79%). The positive rate of EBV-DNA in different diseases was different. Conclusions Infection rate of EB virus in our hospital is comparable with that in other regions of China. The infection rate varies in different seasons, ages and departments in the hospital. The clinical manifestations of EB virus infection are complex and varied.

Abstract:
Objective To explore the effect of peroxisome proliferator-activated receptor γ (PPARγ) agonist on the level of oxidative stress and inflammation in gestational diabetes mellitus (GDM) mice. Methods The maternal gestational diabetes mouse model was established in 7-week-old C57/BL6 mice. Twenty-four GDM model mice were divided randomly into two subgroups:GDM group and rosiglitazone (RSG) intervention group. Twelve pregnant mice were selected as control group. The data of weight and glucose were detected on gestation day (GD) 10,12,14,16 and 18. Glucose oxidase-peroxidase method was used to determine the glucose levels in the blood, determination of serum insulin levels by radioimmunoassay (RIA), serum tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6) and interleukin-8(IL-8) levels were measured by enzyme linked immunosorbent assay, serum superoxide dismutase (SOD) activity levels were measured by WST-1, determination of glutathione peroxidase (GSH-Px) content by peroxidase micro assay. Results The body weight(F=306.53,P<0.001)and serum glucose (F=31.20,P<0.001) of pregnant mice were significantly different at different time (all P<0.05). The body weight and serum glucose were also affected by interaction of time and group(all P<0.05). The insulin levels of pregnant mice in each group were significantly different (F=6.33,P=0.009). The levels of oxidative stress (SOD, GSH-Px) and inflammatory factors (TNF-α, IL-6 and IL-8) in each group were significantly different (all P<0.05). Conclusions PPARγ agonist supplement can increase the levels of SOD and GSH-Px, and reduce the levels of TNF-α to improve the environment of oxidative stress and inflammation in gestational diabetes mellitus mice.
