<b>Objective:b> To investigate the rates on prevalence, awareness, treatment and control of hypertension in population older than 15 years of age in Beijing, 2013-2014. <b>Methods:b> A cross-sectional survey was conducted in Beijing between 2013-2014. Stratified multistage random sampling method was used to select representative sample of 13 057 Chinese individuals aged over 15 years, from the general population. Blood pressure was measured for three readings at sitting position after resting for at least five minutes with an average reading recorded. A standardized structured questionnaire was developed to collect history of hypertension and antihypertensive treatment. <b>Results:b> A total of 4 663 community residents aged over 15 years were hypertensive among the 13 057 individuals, with the standardized prevalence rate as 32.7%, in Beijing area. The age-standardized prevalence rates of hypertension appeared 34.6% in men and 30.8% in women. The age-and sexstandardized prevalence of hypertension rates were 33.3% in urban and 24.6% in rural areas. The prevalence of hypertension increased with age and appeared higher in men than in women, in urban than in rural residents. Among the hypertensive patients, rates of awareness, treatment and control were 66.8%, 64.6% and 31.6%, respectively. <b>Conclusion:b> High prevalence of hypertension with low rates on awareness and treatment and control, appeared in the general population of Beijing. Related strategies should be developed regarding prevention, control and management of hypertension, to reduce the burden of this disease.

<b>Objective:b> To estimate the health-adjusted life expectancy (HALE) of adults in Zhejiang province and evaluate the health status of the adults. <b>Methods:b> This study was based on the mortality data collected from Zhejiang Chronic Disease Surveillance Information and Management System, and mortality rates from the underreporting survey and self-reported health data in 2016. Hierarchical Ordered Probit (HOPIT) model was used to estimate the severity-weighted prevalence of disability. Sullivan's method was used to calculate the HALE. <b>Results:b> After adjustment by HOPIT model, the severity-weighted prevalence of disability increased significantly with age (χ(2)=5 795.81,P<0.001), and it was higher in females than in males (χ(2)=5 353.27, P<0.001). The life expectancy and self-evaluated HALE were 59.08 years and 48.68 years, respectively, in those aged ≥20 years, the difference was 10.40 years due to disability. The proportion of HALE loss due to disability in the total life expectancy was 17.61%, and it increased with age. HALE was higher in males than in females (49.21 years vs. 48.14 years), and in urban residents than in rural residents (49.92 years vs. 47.43 years). <b>Conclusion:b> The proportion of loss of HALE in the total life expectancy in adults was high in Zhejiang, and it higher in males than in females, in urban residents than rural residents. Programs on improving health care in women and rural residents should be promoted.

<b>OBJECTIVEb>A randomized trial of breast self-examination (BSE) program was carried out to evaluate whether the intensive BSE can reduce the death number of women from breast cancer.

<b>METHODSb>A total of 266,064 women (age of 30 to 64 years) associated with 519 textile factories in Shanghai had been randomly assigned to a BSE instruction group (132,979 women) or a control group (133,085 women) since 1989. Initial instruction in BSE group included demonstration of proper palpation techniques. It was followed by 2 reinforcement sessions during the subsequent 4 years including video shows, BSE instruction sessions and BSE practice under medical supervision. These activities were continued for 5 years. Attendance at all events was recorded. The cohort was followed through July 2000 for development of breast diseases, and the breast cancer cases were followed up through 2001 for vital status. The data analysis methods used included Kaplan-Meier plots, Log-rank test and Cox modeling.

<b>RESULTSb>Among women under instruction, 864 breast cancers were detected and 133 breast cancer deaths occurred, and 896 breast cancers were detected and 130 deaths recorded in the control group. The tumor size (P = 0.07), TNM stage (P = 0.39) and cumulative breast cancer mortality rate (P = 0.72) were not significantly different between the 2 groups. However, more and smaller fibroadenomas were detected in the instruction group than in the control group (P < 0.01).

<b>CONCLUSIONb>Intensive instruction in BSE can not reduce mortality rate of breast cancer, but more and smaller benign breast lumps can be detected.

<b>BACKGROUNDb>The receptor tyrosine kinase-like orphan receptor 2 (ROR2) gene has been recently shown to play important roles in palatal development in animal models and resides in the chromosomal region linked to non syndromic cleft lip with or without cleft palate in humans. The aim of this study was to investigate the possible association between ROR2 gene and non-syndromic oral clefts.

<b>METHODSb>Here we tested 38 eligible single-nucleotide polymorphisms (SNPs) in ROR2 gene in 297 non-syndromic cleft lip with or without cleft palate and in 82 non-syndromic cleft palate case parent trios recruited from Asia and Maryland. Family Based Association Test was used to test for deviation from Mendelian inheritance. Plink software was used to test potential parent of origin effect. Possible maternally mediated in utero effects were assessed using the TRIad Multi-Marker approach under an assumption of mating symmetry in the population.

<b>RESULTSb>Significant evidence of linkage and association was shown for 3 SNPs (rs7858435, rs10820914 and rs3905385) among 57 Asian non-syndromic cleft palate trios in Family Based Association Tests. P values for these 3 SNPs equaled to 0.000068, 0.000115 and 0.000464 respectively which were all less than the significance level (0.05/38 = 0.0013) adjusted by strict Bonferroni correction. Relevant odds ratios for the risk allele were 3.42 (1.80 - 6.50), 3.45 (1.75 - 6.67) and 2.94 (1.56 - 5.56), respectively. Statistical evidence of linkage and association was not shown for study groups other than non-syndromic cleft palate. Neither evidence for parent-of-origin nor maternal genotypic effect was shown for any of the ROR2 markers in our analysis for all study groups.

<b>CONCLUSIONb>Our results provided evidence of linkage and association between the ROR2 gene and a gene controlling risk to non-syndromic cleft palate.

<b>BACKGROUNDb>Durable polymers used for first-generation drug-eluting stents (DES) potentially contribute to persistent inflammation and late DES thrombosis. We report the first in human experience with the rapamycin-eluting biodegradable polymer coated cobalt-chromium FIREHAWK stent with abluminal groove.

<b>METHODSb>A total of 21 patients with stable or unstable angina, or prior myocardial infarction, with single de novo native coronary stenoses < 30 mm in length in vessel sizes ranging from 2.25 to 4.0 mm were enrolled. The primary endpoint was major adverse cardiac events (MACE) at 30 days defined as the composite of cardiac death, myocardial infarction (Q and non-Q), or ischemia-driven target lesion revascularization. Secondary endpoints include device, lesion, and clinical success rates, 4-month in-stent late lumen loss by quantitative coronary angiography (QCA), proportion of uncovered or malapposed stent struts by optical coherence tomograpphy (OCT) at 4 months, and MACE at 4, 12, 24 and 36-month follow-up.

<b>RESULTSb>Device success was 95.7%, lesion and clinical success was 100.0%. There were no MACE events at 30 days. One patient died of non-cardiac hemorrhagic stroke 5 days after index procedure. At 4 months, in-stent late loss was (0.13 ± 0.18) mm, and complete strut coverage was 96.2% by OCT with 0.1% strut malapposition. At 4-month follow-up there was no additional MACE events, and a single target vessel (non-target lesion) revascularization.

<b>CONCLUSIONSb>The FIREHAWK abluminal groove biodegradable polymer rapamycin-eluting stent demonstrated feasibility, safety and efficacy in this first in human experience. OCT findings indicated excellent stent strut coverage 4 months after implantation. Larger studies are required to confirm whether the early FIREHAWK stent results translate into longer term restenosis and thrombosis benefits.

<b>Objective:b> To investigate the economic burden of hepatitis C patients and related factors in Guangdong province. <b>Methods:b> In this study, cluster sampling method was used to select cases, including acute hepatitis C, chronic hepatitis C and liver cirrhosis cases from eligible outpatients and inpatients in 1 or 2 large general hospitals in all the 21 cities in Guangdong province. Questionnaire survey was conducted for all the hepatitis C patients to analyze their economic burden, while multivariate linear regression model was used to identify the related influencing factors. <b>Results:b> A total of 356 hepatitis C patients were enrolled in the study, with 176 outpatients (49.4%) and 180 inpatients (50.6%) respectively. The average age of the study subjects was (44.79±11.73) year-olds. The annual direct economic costs of patients with acute hepatitis C, chronic hepatitis C and liver cirrhosis were 10 703.22 (IQR: 7 396.75-16 891.91), 14 886.63 (IQR: 7 274.00-30 228.25) and 28 874.00 (IQR: 13 093.69-56 350.00) Yuan (RMB) respectively. The annual indirect costs appeared as 2 426.99 (IQR: 1 912.18-7 354.52), 3 235.99 (IQR: 1 323.81-6 619.07) and 5 442.35 (IQR: 3 235.99-10 296.33) Yuan (RMB) respectively. The annual intangible costs were 5 000.00 (IQR:2 000.00-10 000.00), 10 000.00 (IQR: 4 000.00-30 000.00) and 10 000.00 (IQR: 3 000.00-100 000.00) Yuan (RMB) respectively. The annual total costs were 22 306.17 (IQR: 14 581.24-50 569.17), 38 050.33 (IQR: 17 449.57-68 319.62) and 80 152.18 (IQR: 40 856.09-228 460.79) Yuan (RMB) respectively. Results from the multiple linear regression analysis showed that factors as: annual hospitalization days, annual number of outpatient visits, annual number of hospitalization, type of disease and the levels of the hospitals were related to the economic burden of patients with hepatitis C. <b>Conclusion:b> Patients with HCV-related diseases presented serious economic problem which calls for close attention in Guangdong province.

<b>Objective:b> Data from the surveillance program was collected, to analyze the situation of hospitalization and cases of death with recorded causes, in Shenzhen, from 1995 to 2014. Situation of hospitalization and causes of deaths were studied in Shenzhen which had been a fast-developing city with growing number of immigrants so as to provide reference for decision-making on related prevention and control strategies. <b>Methods:b> Data on hospitalizations and deaths collected from the surveillance program, were classified by both International Classification of Diseases (ICD)- 9 and ICD-10. A database was constructed with methods on related descriptive and trend analysis. <b>Results:b> Around 6.3 million inpatients were seen in the past two decades in Shenzhen. The top five diseases for hospitalization were pregnancy childbirth and puerperium complications, respiratory diseases, injury and poisoning, digestive system diseases and circulatory system diseases, that accounting for 68.4% of all the hospitalization burden. The number of inpatients increased annually, with an 11 times increase during the past two decades. Proportions for pregnancy childbirth and puerperium complications, circulatory system diseases and urinary system diseases all showed increasing (χ(2)=53 806.94, 6 893.95 and 15 383.14, P<0.01), while proportions for injuries and poisoning, respiratory diseases, digestive system diseases showed a declining trend (χ(2)=131 480.09,1 711.84 and 11 367.66, P<0.01). Number of cumulative inpatient deaths exceeded 60 000, with the top five causes as malignant tumor, circulatory system diseases, injury and poisoning, respiratory system diseases and digestive system diseases, that accounting for 82.28% of all the inpatient deaths. Deaths due to circulatory system diseases, injury and poisoning increased and then decreased. Malignant tumor and respiratory diseases-induced deaths showed an increasing trend (χ(2)=1 546.48, 309.55, P<0.01), while induced deaths from disease of the other systems showed slight changes. The overall case fatality rate showed an annual decline (χ(2)=4 378.63, P<0.01), from 2.23% in 1995 to 0.74% in 2014, with mortality attribute to tumor, circulatory system disease decreased significantly. <b>Conclusions:b> Shenzhen had been under an ageing transition, with relatively young population living in the city. Chronic diseases such as tumor gradually had become the major causes for heavy hospitalization burden on the population of Shenzhen.
