Objective:To make a preliminary application of the assessment system for cancer pain management and find insuffi-ciency in the clinical practice of cancer pain diagnosis and treatment. Methods:Data from 41 doctor questionnaires, 43 nurse question-naires, 50 patient questionnaires, and 12 ward questionnaires from the tumor departments of 3 hospitals were analyzed, and the insuffi-ciency in cancer pain management was determined. The wards in the tumor and non-tumor departments related to oncology were as-sessed using rank test, and differences between the 2 wards were investigated. Results:The average scores of doctor, nurse, and wards were 85.41±5.93, 88.46±5.09 and 83.75±3.11, respectively, whereas patient score was 68.67±7.14. To further analyze the patient subsys-tem by converting into a hundred-mark system, the effectiveness and safety scores for the pain management was 81.69±7.71. However, patients' opinion score on pain treatment was only 55.78±11.37. The score of tumor departments was 82.22±2.03, whereas related non-tumor departments had a score of 39.27 ± 3.58. Wilcoxon W value was at 120.0 with P<0.01 after rank test. Conclusion:Education on patients' opinion on cancer pain management should be promoted in the tumor wards, and continuous education on cancer pain diagno-sis and treatment is needed in the non-tumor departments relative to oncology.

Objective To investigate the effectiveness and safety of intranasal different dose of dexmedetomidine for pediatric echocardiography sedation and to discuss the factors concerning recovery.Methods In a single-blinded randomized clinical trial,183 children were studied with a range of 2months and 33 months of age,and American Society of Anesthesiologists(ASA) physical status Ⅰ to Ⅱ.Those children were divided randomly into one of three groups.Groups D1,D2,and D3,which were received intranasal dexmedetomidine 1.0,1.5,and 2.0 μg/kg,respectively.The induction time,recovery time,examination time,and total sedation time were compared.The success rate of sedation and the occurrence of any side-effects with the drug were compared.Sex,age,weight,dose,induction time,and examination time were used as independent valuations,the recovery time was used as dependent valuation,and then the multiple linear regression analysis was performed to filtrate and formulate the valuable factors influencing recovery time.Results The induction time had no significantly difference among groups (P ＞ 0.05).The recovery time of group D3 was longer than group D1 and group D2 (P ＜ 0.05).The total sedation time of group D3 was longer than group D1 (P ＜ 0.05).The success rate of sedation and the incidence of sideeffects had no significantly difference among groups (P ＞0.05).Children's weight and medicine dose were found to affect recovery time.Conclusions Intranasal dexmedetomidine 1 ～ 2 μg/kg could be used effectively and safely in children undergoing echocardiography examination.Weight and dose were considered as key indexes to predict recovery time.

Objective To evaluate the pharmacodynamics of oral chloral hydrate sedation for echocardiography in pediatric patients with congenital heart disease (CHD).Methods Two hundred ASA physical status Ⅱ-Ⅳ pediatric patients with CHD, aged 5-620 days,scheduled for elective echocardiography,were enrolled in the study.The dose of oral chloral hydrate was set at 50 mg/kg in the first pediatric patient.The oral dosage was determined by up-and-down sequential experiment.Each time the oral dose increased/decreased by 10％ in the next pediatric patient.The pharmacodynamics was analyzed based on the dose-response model to determine the 50％ effective dose (ED50),95％ effective dose (ED95) and 95％ confidence interval (95％ CI) of chloral hydrate for sedation.The covariates (age,gender,time period of administration,fasting time,sleeping at 2 h before sedation,premature and cyanotic CHD) were introduced into the dose-response model,and the effect of each covariate on the pharmacodynamics of chloral hydrate sedation was evaluated.Results The ED50 of chloral hydrate for sedation during echocardiography was 42.2 mg/kg (95 ％ CI 40.2-44.2 mg/kg), ED95 was 67.4 mg/kg (95％ CI 53.7-81.1 mg/kg) in the pediatric patients with CHD.Each covariate provided no effect on the pharmacodynamics of chloral hydrate sedation (P ＞ 0.05).When fasting time and premature were introduced into the dose-response model,95％ CI of the slope of dose-response curve included 0.When age which was stratified was introduced into the dose-response model,it was difficult to fit or the data seriously deviated from the clinical data.Conclusion The ED50 and ED95 of chloral hydrate for sedation during echocardiography were 42.2 mg/kg (95％ CI 40.2-44.2 mg/kg) and 67.4 mg/kg (95％CI 53.7-81.1 mg/kg),respectively,in the pediatric patients with CHD.Gender,time period of administration,sleeping before sedation and cyanotic CHD do not affect the pharmacodynamics of oral chloral hydrate sedation,while the effect of age,fasting time and premature needs further determination.

Background: Hepatocyte nuclear factor 4α (HNF4α) plays an important role in the development of liver,and studies demonstrate that it is correlated with the pathogenesis of hepatocellular carcinoma (HCC).However,the regulatory effect of HNF4α on expression of vascular endothelial growth factor (VEGF) in human HCC cell lines and tube formation of human umbilical vein endothelial cell (HUVEC) is not yet clear.Aims: To investigate the effect of HNF4α on expression of VEGF in human HCC cell lines and tube formation of HUVEC.Methods: Lentiviral vector overexpressed HNF4α was constructed,and then transfected into HepG2 and SMMC-7721 cells (experimental group),cells transfected with lentiviral blank vector and cells without transfection were served as negative control group and blank control group,respectively.The mRNA and protein expressions of HNF4α,VEGF were detected by qRT-PCR and Western blotting,respectively.The conditioned media of HepG2 and SMMC-7721 cells were co-cultured with HUVEC,and number of HUVEC tube formation was measured.Results: HepG2 and SMMC-7721 cells with stable overexpression of HNF4α were successfully established.Compared with negative control group and blank control group,mRNA and protein expressions of VEGF in experimental group were significantly decreased (P＜0.05),and number of HUVEC tube formation was significantly decreased (P＜0.05).Conclusions: HNF4α can significantly inhibit the expression of VEGF in HepG2 and SMMC-7721 cells and tube formation of HUVEC.

OBJECTIVETo evaluate the effect of integrative medical treatment (IMT) with serial Chinese recipes on quality of life (QOF) of rehabilitation stage in SARS patients.

METHODSEighty-five SARS patients of rehabilitation stage were enrolled in the clinical study. They were divided into the IMT group (62 patients received serial Chinese recipes and western medicine) and the control group (23 patients received western medicine alone). The serial Chinese recipes were given according to patients' syndrome, one dose per day for oral intake for 3 weeks. QOF scoring in patients was observed.

RESULTSQOF scoring in the IMT group before treatment was not significantly different from that in the control group. After 3 weeks treatment, it improved to some extent in both groups, but the improvement in the IMT group was superior to that in the control group in respect of total score and score of psychologic emotional factors.

CONCLUSIONSerial Chinese recipe could improve QOF of rehabilitation stage in SARS patients.
