Abstract:
  Objective  The aim is to analyze the spatial-temporal correlation of dysentery incidence in 31 provinces, municipalities and autonomous regions in China from 2004 to 2016, and to predict the short-term incidence of dysentery in China.  Methods  Data about the incidence of dysentery from 2004 to 2016 was collected. Arcgis and Geoda were used to create visualized grading maps and analyze spatial correlation. The auto-regressive integrated moving average model (ARIMA)was used to predict the incidence of dysentery in 2017 and evaluate the prediction accuracy of the model.  Results  The incidence of dysentery in China declined with each passing year from 2004 to 2016. The incidence of dysentery in the western region was significantly higher than the eastern region, except high incidence rate in Beijing and Tianjin. There was no significantly global correlation in the incidence rate, but there was local aggregation. Qinghai had turned from high-level aggregation to low-level accumulation. Inner Mongolia and Shanxi had changed from no local aggregation to low-high accumulation. Shaanxi has long been high-high, and the southeast coastal areas had been low-low accumulation for a long time. The optimal model ARIMA (1, 0, 0) (2, 1, 1)12 was established to predict the incidence of dysentery, and the prediction results were roughly consistent with the observations.  Conclusion  The incidence of dysentery from 2004 to 2016 is not spatially mobile but clustered. The incidence of dysentery in Beijing, Tianjin, Shaanxi and most of the western regions is severe. The ARIMA model is suitable for forecasting the incidence of short-term dysentery. And our analysis may help prevent and control the incidence of dysentery in China.

Abstract:
  Objective  The aim is to analyze the spatial epidemiological characteristics for human infection with avian influenza H7N9 in Fujian Province, so as to provide scientific evidence for developing and adjusting related control strategies.  Methods  The epidemiological data of human infection with H7N9 avian influenza in Fujian Province, from 2013 to 2017 was analyzed by SAS 9.2, ArcGIS 10.3 and SaTScan 9.4 software.  Results  There were a total of 108 cases and 28 deaths reported in Fujian Province, up to December 31, 2017. The case fatality rate was 25.93%.96.30% of cases were sporadic. There were more incidences in winters and springs, more incidences in rural areas. The global spatial autocorrelation and high/low clustering analysis indicated that clusters at the county level were in the shore areas (Z=3.74, P < 0.001; Z=5.26, P < 0.001). The cities of Changle, Fuqing, Jinjiang and Siming were the high-high clustered areas and local hot-points. There were two clusters, from December 2014 to March 2015, the most likely cluster regions was centered around Zhangpu County with a radius of 63.04 km (RR=4.72, LLR=11.41, P < 0.001). The secondary cluster regions was centered around Fuqing City with a radius of 81.98 km (RR=4.07, LLR=7.96, P=0.037).  Conclusions  Human infection with avian influenza H7N9 in Fujian Province is spatially and temporally clustered. The measures of prevention and control should be focused on high incidence seasons and key regions, and the surveillance of etiology should be strengthened.

Abstract(234) HTML (155) PDF(24)
Abstract:
  Objective  To investigate the effect of genetic variants in STAT4 and its interaction with exercise on the pathological characteristics of patients with liver cancer.  Methods  In the 601 new patients with primary liver cancer, multivariate Logistic regression model was used to analyze the genetic association with the risks of advanced stage and portal vein tumor thrombosis at first diagnosis for patients. The multiplicative interaction term and the "Delta" method were used to evaluate the multiplicative and additive interactions, respectively.  Results  Under the dominant model, the rs897200 variant showed a marginally statistical association with the risk of advanced liver cancer at first diagnosis for patients (adjusted OR=0.64, 95% CI: 0.41-1.01, P=0.057). Carriers of the rs1031507 CC+AC genotype had a lower risk of advanced liver cancer than those with the AA genotype (adjusted OR=0.63, 95% CI: 0.40-0.99, P=0.046). In the crossover analysis, compared with the patients who carried the rs897200 CT+CC genotype and had exercise, the TT genotype carriers being lack of exercise showed an increased risk of advanced cancer (OR=3.71, 95% CI: 1.97-6.98, P < 0.001). Similarly, the rs1031507 AA genotype and the lack of exercise jointly increased the risk of advanced cancer (OR=3.78, 95% CI: 2.01-7.13, P < 0.001). However, no statistical interactions between the genetic factors and exercise were observed for liver cancer stages.  Conclusion  The genetic variants in STAT4, rs897200 and rs1031507, solely or jointly with exercise, affect the clinical stage of liver cancer at patients' first diagnosis.

Abstract:
  Objective  To identify the relationship between a set of long non-coding RNA (lncRNA) signature and the prognosis of diffuse large B-cell lymphoma (DLBCL) patients, so as to evaluate their prognostic significance.  Methods  LncRNA expression profiles and clinical data of DLBCL patients were extracted from the gene expression omnibus (GEO) database: GSE31312 (n=424, training set) and GSE10846 (n=295, validation set). In the training set, a set of 8-lncRNA signature associated with the overall survival (OS) of DLBCL patients was established through least absolute shrinkage and selection operator (LASSO) combined with stability selection method and multivariate Cox regression analysis.Based on this 8-lncRNA signature, the patients in each data set could be classified into high-risk group and low-risk group. The survival curves of patients in both groups were compared by log-rank test. Then three Cox proportional hazard models, namely, international prognostic index (IPI), lncRNA signature and IPI+lncRNA signature model were constructed. The incident/dynamic receiver operating characteristic (ROC) curves method was applied to evaluate and compare their predict accuracy.  Results  A total of 8 lncRNAs related to the prognosis of DLBCL were found.In the training and validation sets, the difference of survival curves between high-risk group and low-risk group was statistically significant respectively (training set: χ2=73.1, P < 0.001, validation set: χ2=13.4, P < 0.001), the difference of C-index between IPI+lncRNA signature model and either of the other two models were also statistically significant (training set: IPI+lncRNA vs. IPI: Z=76.536, P < 0.001; IPI+lncRNA vs. lncRNA: Z=17.714, P < 0.001;validation set: IPI+lncRNA vs. IPI: Z=42.427, P < 0.001; IPI+lncRNA vs. lncRNA: Z=30.587, P < 0.001).  Conclusions  The 8-lncRNA signature can be used as a composite prognostic biomarker of DLBCL. Besides, lncRNA combined with IPI has better prognostic predict ability than IPI alone.

Abstract:
  Objective  The aim is to understand the underestimation of body weight status and its associated factors among overweight and obese adults in China.  Methods  Nationally representative data were collected in 2013 by the China Chronic Disease and Risk Factor Surveillance which used a multistage stratified cluster sampling method. A total of 87 552 overweight and obese adults aged ≥ 18 years old were included. Demographic characteristics, weight perception and disease status were obtained from in-person interviews. Height, weight and blood pressure were measured through physical examination. Venous blood samples were obtained and assayed for fasting plasma glucose, 2-hour oral glucose tolerance test, total cholesterol, triglycerides, low-density lipoprotein cholesterol and high-density lipoprotein cholesterol. Complex sampling was weighted and multiple logistic regression models were used for analyzing.  Results  Among overweight and obese adults, 74.7% (95% CI: 73.3%-76.1%) underestimated their weight status. The mild underestimation rate was 60.7% (59.6%-61.7%) while the severe was 14.0% (13.1%-14.9%). The aged, low education level, low annual income, rural area and obesity were risk factors for both weight status underestimation and severe underestimation (all P < 0.05). Awareness of having hypertension and dyslipidemia were protective factors (all P < 0.05).  Conclusions  Most overweight and obese adults in China underestimated their own weight status, which was affected by age, education and income level, awareness of having chronic diseases and other factors. Targeted interventions should be carried out for different characteristic groups.

  Objective  The aim is to investigate the association between body mass index (BMI) and risk of all-cause mortality among patients with type 2 diabetes.  Methods  A total of 17 638 patients with type 2 diabetes registered in the management of National Basic Public Health Services in two areas of southern and northern Jiangsu were recruited. Cox proportional risk regression model was used to calculate the hazard ratio(HR) value and 95% confidence interval (95% CI) of different BMI groups in the follow-up period.  Results  The subjects were followed up for a total of 77 451 person-years with an average duration of 4.39 years, and 1 274 patients died during the follow-up period. The number of death in low weight group (BMI < 18.5 kg/m2), normal weight group (18.5 kg/m2 ≤ BMI < 24 kg/m2), overweight (24 kg/m2 ≤ BMI < 28 kg/m2) and obese group (BMI ≥ 28 kg/m2) were 39, 575, 484 and 176 respectively.The corresponding mortalities were 15.6%, 9.5%, 6.2% and 5.1%, respectively. Compared to normal weight group, the adjusted HR of all-cause mortality in low weight, overweight and obese group were 1.66 (95% CI: 1.20-2.30), 0.68 (95% CI: 0.61-0.77), 0.58 (95% CI: 0.48-0.68), respectively.  Conclusions  Low-weight patients have the highest risk of all-cause mortality compared with normal counterparts, while both overweight and obese people have a lower risk of death. Overweight and obesity may reduce the risk of all-cause mortality in type 2 diabetic patients.

Abstract:
  Objective  To investigate the prevalence and related factors of type 2 diabetes mellitus(T2DM) and its associated renal insufficiency in adult residents of a community in Shanghai.  Methods  A total of 9 257 residents aged 20-75 years old in a community of Shanghai were selected by random cluster sampling. All participants were interviewed to complete questionnaires, physical examination, examination of blood, urine and common biochemical indicators for T2DM, renal insufficiency and other related factors. Then the SPSS 19.0 software was used for analysis.  Results  Of the 9 257 respondents, eligible data of 8 207 subjects were enrolled in the study. The prevalence of T2DM was 12.7% (95% CI: 12.0%-13.4%), and the prevalence of its associated renal insufficiency was 15.4% (95% CI: 12.3%-18.4%), and majority of patients (65.8%) were in the early stage. Among the T2DM patients in this survey, the prevalence of renal insufficiency in obese patients was higher than that in patient with the normal body mass index. Logistic regression analysis showed that elder (OR=1.35), central obesity (OR=1.50), hyperuricemia (OR=2.51) were independent risk factors related with renal insufficiency in T2DM patients.  Conclusions  Renal insufficiency has become one of the important public health problems in T2DM patients. It shows a more urgent need for early prevention and control of CKD to prevent the incidence of end-stage renal disease and related complications in T2DM patients with advanced age, obesity, and hyperuricemia.

Abstract:
  Objective  To further explore the relationship between blood lipid and arterial stiffness by complex blood lipid profiles.  Methods  431 subjects with hypertensions or inpatients with suspension of atherosclerosis-related diseases were included. The subjects were grouped into Group A (no history of hypertension and dyslipidemia), Group B (with history of dyslipidemia but not hypertension), Group C (with history of hypertension but not dyslipidemia) and Group D (with history of hypertension and dyslipidemia). The profiles of atherogenic index of plasma(AIP), non-high density lipoprotein-cholesterol (non-HDL-C), TC/HDL-C and atherogenic index (AI) were calculated based on lipid indexes of total cholesterol (TG), triglyceride (TG), high density lipoprotein-cholesterol (HDL-C) and low density lipoprotein-cholesterol (LDL-C). Brachial-ankle pulse wave velocity (baPWV) as well as blood lipid profiles were analyzed with comparisons and correlation analyses among groups.  Results  Total TC, TG, HDL-C, AIP, AI, non-HDL-C and TC/HDL-C were different with statistical significance (all P < 0.05). Multivariate linear partial correlation analysis of hypertensions showed that TG, HDL-C, AIP, AI, TC/HDL-C (all P < 0.05), but not TC, LDL-C and non-HDL-C (all P>0.05) were correlated to baPWV.  Conclusion  The blood lipid profiles of AI, AIP and TC/HDL-C may be correlated to baPWV, which may better reflect the trend of blood lipid and arterial stiffness in hypertensions.

Abstract:
  Objective  To explore the influencing factors of readmission in coronary heart disease patients with heart failure by constructing a multilevel Cox regression model.  Methods  A total of 1 433 coronary heart disease patients with heart failure were consecutively enrolled, from two hospitals in Shanxi Province from January, 2014 to December, 2017. Patients' medical records (including baseline data, examination and treatment) were recorded and patients were followed up. The median follow-up period was 23 months. Univariate Cox regression analysis and mutivariate Cox regression analysis were used to screen the independent variables. Two-level Cox regression model was used to analyze the influencing factors.  Results  Rehospitalization occurred in 436(30.4%) cases. Two-level Cox regression model showed that advanced age(HR=1.010, 95% CI: 1.001-1.019, P=0.032), male(HR=1.234, 95% CI: 1.009-1.509, P=0.040), physical labor(HR=1.458, 95% CI: 1.036-2.050, P=0.030), urban medical insurance (HR=1.513, 95% CI: 1.120-2.043, P=0.007), and prolonged QRS interval (HR=1.004, 95% CI: 1.001-1.008, P=0.018) were independent risk factors for readmission coronary heart disease patients with heart failure. High urine specific gravity(HR=0.000, 95% CI: 0.000-0.059, P=0.021) was a protective factor.  Conclusions  The age, gender, occupation, urban medical insurance, QRS intervall, and urine specific gravity are influencing factors of readmission in coronary heart disease patients with heart failure. Strengthening clinical nursing and monitoring and perfecting social security system can reduce the occurrence of patients' rehospitalization.

Abstract:
  Objective  To explore the prevalence and influencing factors of anxiety and depression among adolescent females.  Methods  Adolescent females aged 10-19 years in Hunan Province were investigated by general information questionnaire, menstrual status questionnaire, generalized anxiety scale (GAD-7) and patient health questionnaire depression scale (PHQ-9).  Results  A total of 2 575 adolescent females were included. The prevalence of anxiety was 9.6%, while the prevalence of depression was 16.4%. Multivariate Logistic analysis showed that among the overall adolescent females, not studying at school, no physical/mental violence, longer average sleep time, no menarche were protective factors for anxiety while higher education level was risk factor; not studying at school, no physical/mental violence, no menarche were protective factors for depression while higher education level was risk factor (all P < 0.05). Among the adolescent females with menarche, not studying at school, no physical/mental violence, longer average sleep time, no dysmenorrhea in the past six months were protective factors for anxiety/depression while higher education level and irregular menstrual cycle in the past six months were risk factors (all P < 0.05).  Conclusions  There is a certain degree of anxiety and depression among adolescent females in Hunan Province. It is suggested that more interventions should be strengthened for high-risk groups.

Abstract:
  Objective  To study the predictive effect of model[GM(1, 1)] in China's maternal and child health indicators, and to predict the future maternal and child health indicators in a short-term, and provide a scientific basis for the gradual improvement of maternal and child health care services in China.  Methods  The maternal mortality rate (MMR), neonatal mortality rate (NMR), infant mortality rate (IMR) and under-five mortality rate (U5MR) were collected from 2008 to 2017 in China. Models were established and MATLAB 2018b software was used for predictive analysis.  Results  The prediction models of maternal mortality rate, neonatal mortality rate, infant mortality rate and under-five mortality rate were as follows: ${\rm{\hat x}}\left( {{\rm{k}} + 1} \right) = - 476.08{{\rm{e}}^{ - 0.09{\rm{k}}}} + 510.28({C_1} = 0.165,{P_1} = 1.000)$, ${\rm{\hat x}}\left( {{\rm{k}} + 1} \right) = - 108.43{{\rm{e}}^{{\rm{ - 0}}{\rm{.09k}}}} + 118.63({C_2} = 0.043,{P_2} = 1.000)$, ${\rm{\hat x}}\left( {{\rm{k}} + 1} \right) = - 160.60{{\rm{e}}^{ - 0.09{\rm{k}}}} + 175.50({C_3} = 0.085,{P_3} = 1.000)$, ${\rm{\hat x}}\left( {{\rm{k}} + 1} \right) = - 224.37{{\rm{e}}^{ - 0.08{\rm{k}}}} + 242.87({C_4} = 0.124,{P_4} = {\rm{ }}1.000)$, the average relative errors were as follows: 3.46%, 0.67%, 1.75% and 2.36%。  Conclusions  The GM (1, 1) is suitable for the prediction of maternal and child health indicators in China, and the fitting accuracy is high. It is predicted that the indicators will continue to decline year by year in the next three years, and relevant departments should strengthen the management work in a targeted manner.

Abstract:
  Objective  To underst and the depression status of disabled elderly in rural areas and to explore its influencing factors.  Methods  Based on the data of China health and retirement longitudinal study (China health and retirement longitudinal study, CHARLS) in 2015, 836 respondents were enrolled. Order logit model was used to analyze the influencing factors of depression status of disabled elderly in rural areas of China and the heterogeneity of the sample was estimated by the degree of disability.  Results  55.74% of the disabled elderly in rural areas had mental sub-health, of which 35.05% were in general depression status and 20.69% were in poor depression status.The basic characteristics, living conditions, health status, socio-economic characteristics and intergenerational support affected the depression status of rural disabled elderly in varying degrees. There was no statistically difference in the influence of the number of children on the depression status in the total sample, but the number of daughters (OR=1.416, 95% CI: 1.055-1.901, P=0.020) and sons (OR=2.012, 95% CI: 1.579-2.564, P=0.043) had negative effect on the depression status of moderate and severe rural disabled elderly respectively. Same village with grandchildren (OR=0.732, 95% CI: 0.554-0.966, P=0.028) had statistically difference in the influence on the depression status of rural disabled elderly, it had positive effect on the depression status of severe rural disabled elderly (OR=0.527, 95% CI: 0.341-0.813, P=0.034).  Conclusion  The depression status of the disabled elderly in rural areas is affected by multiple factors. The phenomena of "raising children and preventing old age" and "more children and more happiness" are gradually disappearing. The phenomenon of "next generation relatives" still exists.

Abstract:
  Objective  To analyze the epidemiological characteristics of mumps in Hefei City from 2011 to 2016, in order to provide a basis for effective prevention of mumps.  Methods  The data of mumps in Hefei City from 2011 to 2016 was analyzed by descriptive epidemiology.  Results  There were a total of 9 678 cases of mumps in Hefei City from 2011 to 2016. The average annual incidence was 22.7/100 000, with the highest in 2013 being 40.56/100 000. Mumps had obvious seasonality with high incidence in spring. Mumps cases increased in winter but the peak was not distinct. The group with the largest number of cases was mainly students, accounting for 64.5% of the total number of cases, followed by childcare and residentially-scattered children. The average annual morbidity of nine counties existed differences(χ2=256.845, P < 0.001).  Conclusions  There was a high incidence of mumps in Hefei City from 2011 to 2016. More effective measures should be taken to prevent the incidence of mumps and reduce the spread of mumps virus.

Abstract:
  Objective  To compare epidemiology characteristics and control measures of dengue fever (DF) outbreaks in public places in Shenzhen and Hong Kong and integrate the advantages for better response to DF outbreaks.  Methods  Data of DF cases and mosquito vector surveillance in Shenzhen and Hong Kong were collected for descriptive epidemiological analysis and measures of mosquito control were compared.  Results  A total of 19DF cases were recorded in 13 d among six districts of Hong Kong, the male: female ratio was 1:0.9. In Shenzhen, 20 cases were recorded in 33 d, the cases were distributed in three sub-districts, the Male: female ratio was 1:0.82; Age difference between Shenzhen and Hong Kong was statistically significant (Z=-2.855, P=0.004). The time interval between date of onset and laboratory confirmation ranging from 5.5 to 8.5 d (median: 7d) in Hong Kong, and ranged from 1.5 to 5.4 d (median: 2 d) in Shenzhen, the difference was statistically significant (Z=-3.818, P < 0.001). On the 4th day of the outbreak, Hong Kong declared 30 d closure for anti-mosquito operations with a range of 500 m, and monthly area ovitrap index (AOI) was used to monitor the territory-wide situation of Aedes albopictus. On the 2nd day of the outbreak, Shenzhen declared source closure for mosquito control with a range of 400 m and emergency vector surveillance was conducted, using Breteau Index (BI) and Human-baited double net trap(HDN) every 3 d.  Conclusions  The nature, scale, time and place of the two local DF outbreaks in Shenzhen and Hong Kong are similar. The prevention and control system is more sensitive and prompt, the ability of early detection is stronger, mosquito vector surveillance program is more comprehensive and the frequency is higher in Shenzhen. The epidemic information dissemination and risk communication with media is more active, mosquito management and control is more professional in Hong Kong.

Abstract:
Wu Lien Teh (1879-1960), a world-renowned health and epidemic prevention expert, was a pioneer in public health and medical education in China. With his scientific ideas and methods, he extinguished the plague epidemic in northeast China which shocked the world at the beginning of the 20th century. He proposed and enriched the theory of pneumonic plague, and his work marked a milestone in the world's plague prevention and treatment. He established a scientific health and epidemic prevention system in China, promoted the reform of medical education, established modern medical institutes and hospitals, founded the Chinese Medical Association, helped reclaim the right of port quarantine, strengthened the anti-opium campaign, and promoted cultural exchanges between Chinese and western medicine. He was knowledgeable and far-sighted, and committed to the practice and research of infectious disease prevention and treatment, promoting the development of China's public health, which has a far-reaching impact on China and the world.
