Objective To investigate the awareness and utilization of community family doctor services of residents in Beijing and analyze its influential factors.Methods Multistage random sampling was adopted to enroll residents in Beijing from eight community health centers in Haidian District, Xicheng District and Daxing District,to investigate the awareness and utilization of community family doctor services.Customized questionnaires were recovered for descriptive statistics and influential factor analysis.Results All the 3 008 effective questionnaires were recovered.The results found that 92.2% of the residents used community family doctor services.Higher utilization rates of community family doctor services was found among those residents of chronic diseases,those with their family′s annual average outpatient expenses in the medium level,those with their first choice of medical visits in the community health centers,and those who are aware of family doctor service.Services of the most frequent use in the recent year were physical examination and follow-up phone call(87.3% and 73.4% respectively);those of lower frequency were door-to-door service,health assessment,preventive health care,physical examination,health education and consulting,and rehabilitation service.Factors of statistical significance on utilization of community health services were health condition,financial condition and awareness of community family doctor service(P<0.05).Conclusions Residents in Beijing have a high awareness and utilization of community family doctor services,yet some items of services are seldom used.Health condition,financial condition and awareness of community family doctor service are major influential factors for utilization of community health services.

Vasohibin-1 (VASH1),which is induced in response to angiogenic stimuli such as vascular endothelial growth factor (VEGF) and fibroblast growth factor (FGF)-2,has recently been isolated as a novel negative feedback inhibitor of angiogenesis.Several studies have demonstrated that VASH1 plays important roles in the development of various tumors and it would potentially be a biomarker and a candidate for molecular targeted therapy for patients with cancer in the future.

Objective To learn the awareness,attitude and behavior changes of medical workers to the family doctor service and the influential factors on their utilization of such service since the service is in place.The purpose is to provide theoretical basis to establish the family doctor service model and the incentive mechanism in line with the development of community health service in Beijing.Methods Eight community health centers were sampled randomly from three representative areas of Haidian,Xicheng and Daxing districts,which were grouped randomly as one intervention group and one control group.All the medical workers surveyed were subj ect to the research.The control group was managed as to the existing management mode,and the intervention group was classified and managed according to the new family doctor service model.A questionnaire survey was made to collect data from the baseline and final stages.Comparisons were made among the districts,institutions,and before-after intervention of the institutions themselves to evaluate the effects of the service model and incentive mechanism.Results The survey found a higher awareness by medical workers to such service,higher recognition and satisfaction, and lower rate of services provided by medical workers.The logistic regression analysis found the influential factors for willingness of medical workers to work as family doctors,include group difference, workload changes after signoff as family doctors,residents′acceptance of the community first visit system,recognition or not for whether a family should have a community service team,residents′acceptance,and the general comments on family doctor service (P< 0.05 ).Conclusions Higher incentives of community doctors to embrace family doctor service,calls for the medical workers to change their perception,better incentive mechanism and greater promotion efforts for family doctors′services.

Objective To explore the role of the SerpinB5 and β-catenin in occurrence and development of the primary hepatocellular carcinoma (HCC). Methods The expressions of SerpinB5 and β-catenin protein and mRNA in carcinoma tissues and paracancerous tissues of 60 patients with primary HCC were detected by immumohistochemistry and real-time quantitative reverse transcriptional polymerase chain reaction (RT-PCR) methods. Results The positive expression rate of SerpinB5 protein and SerpinB5 mRNA in carcinoma tissues were significantly lower than those in paracancerous tissues:25.0%(15/60) vs. 63.3%(38/60) and 1.12 ± 0.43 vs. 5.19 ± 0.39, and there were statistical differences (P<0.01). The positive expression rate of β-catenin protein and β-catenin mRNA in carcinoma tissues were significantly higher than those that in paracancerous tissues: 65.0%(39/60) vs. 31.7%(19/60) and 4.23 ± 0.25 vs. 1.19 ± 0.17, and there was statistical difference (P<0.01). Decreased SerpinB5 expression was associated with higher serumα-fetoprotein level, larger tumor size, poor differentiation, advanced TNM stage, capsule invasion and tumor thrombosis (P < 0.01 or 0.05). Increased β-catenin expression was associated with poor differentiation, advanced TNM stage, capsule invasion and tumor thrombosis (P < 0.01 or < 0.05). The correlation analysis result showed that SerpinB5 had negative correlation withβ-catenin (carcinoma issues:r=-0.346, P=0.001;paracancerous tissues:r=-0.258, P = 0.024). Conclusions The abnormal expression of SerpinB5 and β-catenin may contribute to the progression and biologically malignant behavior of primary HCC, and SerpinB5 and β-catenin exists synergistic effect in the occurrence and development of primary HCC.
