Objective: To study the status and identify the determinants of outpatient service utilization of rural floating population in Beijing who have different accumulated residence time.Methods: The survey data of rural floating population health and health care services in Beijing in 2014 were used, and the migrant population aged 18 years and above were taken as the research object.Whether to use outpatient service within two weeks was taken as dependent variable, gender, age, education level, self-assessment score of socioeconomic status, accumulated residence time in Beijing, health insurance, average household income, suffering from high blood pressure or diabetes as independent variables.Logistic regression model was used to analyze the influencing factors.Results: The average age of the research object was 36.7 years, with mostly secondary education.The average accumulated residence time in Beijing was 8.4 years.The two-week prevalence rate was 10.3%, the two-week visiting rate calculated by person-time was 6.0%.The Logistic regression model suggested that, socioeconomic status, accumulated residence time and suffering from high blood pressure or diabetes were statistically significant determinants of outpatient service utilization.Conclusion: The research object is a younger and less educated population, their health status is better and outpatient service utilization is lower.It is found that people who have longer accumulated residence time in Beijing have lower outpatient service utilization.This is because people with longer residence time have lower age-adjusted two-week prevalence rate.This is also because people with longer residence time have larger proportion of taking continuous measures under doctor's advice.It does not mean people with longer residence time have lower utilization of medical service.The residence time variable plays the role of proxy variable.It can solve the problem of variables' endoge-neity.At the same time, it can reflect the influence to outpatient services utilization of some determinants,which are not included in the model but varies with residence time.

Objective To construct the luciferase reporter gene vector of cell division cycle 2 (Cdc2) gene promoter and determine its transcriptional activity. Methods Primers were designed based on human Cdc2 promoter sequence from UCSC software. Then Cdc2 promoter from human genome DNA was replicated. After pGL3-Basic vector and Cdc2 promoter were digested with restriction enzymes SacⅠand XhoⅠseparately, Cdc2 promoter was inserted into pGL3-Basic vector. The recombinant plasmid named pGL3-Cdc2-promoter was transiently co-transfected into U2OS cells with control vector pRL-SV40, and then the activity of dual luciferase was detected. Results pGL3-Cdc2-promoter was constructed successfully. The restriction analysis and sequencing proved the entirely correct sequencing results. The luciferase activity was higher in pGL3-Cdc2-promoter/pRL-SV40 group than that of pGL3-Basic/pRL-SV40 group (1.591 5±0.199 8 vs 0.049 9±0.010 4). Conclusion pGL3-Cdc2-promoter can be transcribed and activated in U2OS cells. This study provided an important basis for screening and evaluation of anticancer drugs.

Ossification of the posterior longitudinal ligament (OPLL) is common clinical spinal disorders often occurring in the cervical spine,with the main symptom being nerve compression.The specific mechanism of OPLL remains unclear,but genetic factors,single nucleotide polymorphisms (SNPs),mechanical stimulation,metabolism abnormality might be involved in the etiology of the disease.Multiple genetic and environmental factors may contribute to the development of OPLL.OPLL has prominent genetic characteristic,and it is associated with SNPs of several genes.Here we review the SNPs of several genes (COL11A2,BMP-2,TGF-?1,TGF-?3,NPPS,COL6A1 and Runx2) which contribute to the development of OPLL,hoping to lay a foundation for future study.

Tyrosine kinase inhibitors (TKIs) are used as the primary first-line treatment for advanced hepatocellular carcinoma, and the combination of immune checkpoint inhibitors (ICIs) and angiogenesis inhibitors have also been recommended as first-line treatment recently. For hepatocellular carcinoma patients with portal vein tumor thrombus, hepatic artery infusion chemotherapy (HAIC) is supported by progressively more evidence in improvement in the overall survival benefit. Based on relevant literatures and combined with clinical practices, the authors investigate the clinical application and development trends of TKIs, ICIs and HAIC in the first-line treatment for advanced hepatocellular carcinoma.

Objective To research the early effects and side-effects of the local advanced nasopharyngeal carcinoma patients using intensity-modulated radiotherapy(IMRT)combined with concurrent chemotherapy.Methods From January 2005 to January 2007,60 patients with nasopharyngeal carcinoma of stage m-IV b were received IMRT combined with concurrent chemotherapy in our center.Sixty patients were divided into paclitaxel concurrent group(32 patients)and cisplatin concurrent group(28 patients).The prescribing doses of the primary tumor were 68-72 Gy for each group.The patients of paclitaxel concurrent group patients of the cisplatin concurrent group got earlier radiodennatitis and radiation-induced mucositis but also got significantly higher rate of radiodermatitis,radiation-induced mucositis,radiation-induced leucopenia and gastrointestinal toxicity,as well as the loss of weight.No significant difference was found on liver and renal funcfons between two groups.Four patients(12.5%)of the paclitaxel concurrent group were broken-off,which was much better than the cisplatin concurrent group.There was no significant difference on the specific length of break-off time,the 2-year overall survival rate and the 2-year diseaee-free survival rate between two groups.Conclusions IMRT combined with concurrent chemotherapy of paclitaxel liposome for local advanced nasopharyngeal carcinoma results in less side-effects and better tolerance than IMRT combined with concurrent cisplatin chemotherapy.

Objective To compare two different gastric tube insertion methods on neonatal pain responae.Methods From April to July 2010,47 neonatal patients underwent gastric tube insertion in the neonatal department of our hospital were randomly classified into two groups:the nasal gastric tube insertion group(28 cases) and the oral gastric tube insertion group( 19 cases).Neonatal pain score and incidence of complications during gastric tube insertion between both groups were compared.Results The mean rank of pain scores were significantly higher in the nasal gastric tube insertion group than in the oral gastric tube insertion group.The incidence of pain and complications were higher in the nasal gastric tube insertion group than in the oral gastric tube insertion group.Conclusions The impact of oral gastric tube insertion on neonatal pain response is not significant,and few complications occur during oral gastric tube insertion,so it is worthy of clinical application.

BACKGROUND: Epidemiologic studies have shown an association between higher insulin levels and coronary artery disease, and metabolic studies have associated insulin resistance and compensatory hyperinsulinemia with non-insulin-dependent diabetes mellitus, hypertension, obesity,and lipid disorders.OBJECTIVE: To investigate the relationship between insulin resistance (IR) and erythrocyte insulin receptors (EIRs) in the patients with cerebral infarction (CI).DESIGN: Case-control trial.SETTING: Department of Neurology, China-Japan Union Hospital of Jilin University.PARTICIPANTS: From January 2004 to October 2004, 40 patients with CI, who were in-patients in China-Japan Union Hospital of Jilin University,were selected for the study. Meanwhile, 30 healthy doctors or nurses were recruited as normal controls.METHODS: The levels of blood glucose and serum insulin under fasting and 2-hour after oral glucose tolerance test (OGTT) were detected in the 40 patients with CI and 30 healthy doctors or nurses. Fasting blood glucose multiplied by fasting serum insulin was insulin resistance index (IRI). The number of insulin receptors and their binding affinity on every erythrocyte were determined using modified Gambhir's method. The correlation between the number of EIRs and IRI was analyzed.MAIN OUTCOME MEASURES: Comparison of CI group with controlRESULTS: Data of 40 patients with CI and 30 controls were analyzed, and under fasting and 2-hour after OGTT: The level of serum insulin under fasting and blood glucose, serum insulin at 2-hour after OGTT in CI group were higher than those in normal group [(13.30±5.15), (9.85±4.36) mU/L,(8.27±1.65), (6.32±1.37) mmol/L, (75.21±21.12), (28.26±6.31)mU/L,P ＜ 0.01,EIRs: The number of insulin receptors with high and low affinity and maximum specific binding rate in the patients with CI were significantly less than those in normal group [20.30±4.50, 23.80±4.10; 2 223.80±509.30,2 610.10±435.10; (10.62±3.55)%, (13.21±2.94)%, P ＜ 0.01]. Multiple linear regression analysis and correlation analysis showed the numbers of two types of EIRs in the patients with CI were negatively correlated with IRI (r=-0.458, -0.439, P ＜ 0.01, both).CONCLUSION: Insulin resistance can lead to cerebral infarction. Decrease in insulin receptors may play an importance role in cerebral infarction induced by insulin resistance.
