Objective To analyze the clinical efficacy and safety of amiodarone in the treatment of the elderly patients with ventricular arrhythmia.Methods 136 elderly patients with ventricular arrhythmia were randomly divided into the observation group (n =68cases) and control group (n =68cases).The observation group was given amiodarone by intravenous to treat the elderly ventricular arrhythmia,and patients in the control group were treated with combination therapy.After treatment for 4 weeks,the treatment outcomes were observed and compared.Results The obvious effective rate and total effective rate of the observation group was 51.47％,92.65％).which were significantly higher than those in the control group (51.47 ％,92.65 ％) (P ＜ 0.05).There was no significant difference in the incidence rate of adverse effect between the two groups (P ＞ 0.05).Conclusion Amiodarone has good clinical effect in treatment of elderly patients with ventricular arrhythmia,it is worthy of clinical use.

Objective To make recommendations on the development of private hospitals,by means of investigation and analysis of their business operations.Methods Quantitative and descriptive analysis were used to study business operation data from 2011 to 2013 of the 172 private hospitals,in order to learn their present status and development trends.These data were compared with public hospitals in average to identify problems.Results The revenue and expenditure of theses private hospitals increased at a fast pace,with a revenue growth rate of 22.0% and an expenditure growth rate of 15.7% in 2013.Number of visits gradually improved,with an increase of 12.9%.But the rate of bed occupancy was only 68.1%,lower than the average of public hospitals.Conclusions In view of the low resource utilization,the authors recommend such hospitals to improve hospital management systems,and uphold the integrity of business,so as to compete with public hospitals differentially.

Eight phenolic compounds were isolated from Rhododendron phaeochrysum var. agglutinatum and their sructures were identified as phaeochrysin (1), (2R)-4-(3',4'-dihydroxyphenyl) -2-butanol (2), (-) -rhododendrol (3), rhododendrin (4), (+) -isolariciresinol (5), (-) -lyoniresinol (6), lyoniresinol-9'-O-β-D-xylopyranoside (7), and dihydrodehydrodiconiferyl-3a-O-α-L-rhamnopyranoside (8). Compound 1 is new, and compounds 2, 5-8 were isolated from this plant for the first time.

Objective To explore the reference values of peak expiratory flow (PEF) for 4.0-14.0 years old children in Chengdu.Methods From November 2011 to May 2012,a total of 446 healthy children were enrolled in this study.PEF was measured using expiratory peak velocimeter and lung function meter.Children's age,sex,height and weight were recorded.Impact factors for PEF were investigated by multiple stepwise regression analysis.Results The PEF detected by expiratory peak velocimeter and lung function meter had a good correlation (r =0.920,P ＜ 0.01).Boys own higher peak expiratory flow rate than girls.The level of PEF had the best correlation with height,next was weight and age.The level of PEF increased with the increase of height,age.Some children PEF value was less than 80％ lower limits of lower limits of normal.The PEF could be obtained from height and age.Conclusions Males and females PEF can be calculated according to children's height.Set up the PEF equation about the expiratory peak velocimeter and lung function meter.

Phthalate esters (PAEs)are by far the most widely used plasticisers and are categorized as high and low,depending on their molecular weight.Because of their extensive use,humans are most likely exposed to PAEs in the workplace and home environment through direct as well as indirect sources.Injection,inhalation,intravenous injection and skin absorption are potential pathways of expo-sure.With respect to health effects,phthalates are often classified as endocrine disruptors because of their ability to interfere with the endocrine syste m in the body.Furthermore,PAEs possess reproductive toxicity because of their influence on development of the reproductive system in infancy and development and differentiation of germ cells in adults.PAEs promote pathogenesis and development of liver cancer by activating peroxisome proliferator-activated receptor (PPAR)and DNA methylation.In addition, PAEs,which inhibit the i mmune functions of macrophages and pro mote hypersensitive response,pos-sess immunotoxicity.PAEs are also carcinogens that promote pathogenesis and development of cancers including breast,ovarian and so me other cancers.

AIM:To observe the effects of Dickkopf-3 ( Dkk-3 ) in diabetic retinopathy ( DR ) circulating blood in patients with the expression level, the Dkk - 3 development changes in the diabetic retinopathy of significance in the diagnosis of early DR.
● METHODS: Eighty - five type 2 diabetic patients, included the non - proliferative diabetic retinopathy ( NPDR ) 23 patients, proliferative diabetic retinopathy, proliferative DR ( PDR ) in patients with 30 and non-diabetic retinopathy ( NDR ) with 32 cases. The same period of healthy physical examination was selected as control group ( 80 cases ) . Serum samples were collected, and the relative expression level of Dkk-3 was detected by enzyme - linked immunosorbent assay ( ELlSA) double antibody sandwich assay. The statistical differences were compared between groups.
●RESULTS: The plasma level of Dkk - 3 ( 430. 16 ± 198. 11pg/mL) in DR patients was significantly lower than that in healthy control group (627. 48±294. 45 pg/mL; P<0. 05 ) and NDR patients ( 601. 99 ± 194. 16 pg/mL; P<0. 05). While there was no significant difference in Dkk-3 level between NDR and healthy control group ( P =0. 729). The level of PDR in patients with Dkk-3 (396. 38± 185. 59 pg/mL) was lower than that of NPDR (538. 82 ± 187. 20 pg/mL;P=0. 002).
●CONCLUSION:The decrease of Dkk-3 level may be related to the occurrence and development of diabetic retinopathy, and there is a significant correlation with PDR. Circulating blood Dkk - 3 protein in diabetic retinopathy has a certain differential efficacy, it is likely to become diabetic retinopathy patients peripheral blood test indicators.

Objective To investigate the effects of SAHA on the differentiation of human hepatocellular carcinoma(HCC)SMMC-7721 cells.Methods Cell morphology was examined by light microscopy;Cell viability was determined by MTT assay;The expression of Alpha-fetoprotein(AFP)and proliferating cell nuclear antigen(PCNA)was analyzed with immunocytochemistry;Flow cytometry(FCM)was used to investigate the cell cycle;The expression of p21 WAF1 mRNA was detected by semi-quantitative RT-PCR.Results Light microscopy showed that SMMC-7721 cells induced by SAHA underwent restorational alterations in morphology which were different from those of nontreated cells but were similar to those of normal cells;MTT assay showed that SAHA inhibited the proliferation of SMMC-7721 cells in a dose-dependent and time-dependent way;Immunocytochemistry assay showed that the expression of AFP and PCNA decreased significantly;FCM analysis showed SAHA could arrest SMMC-7721 cells at G0/G1 phase,with an accumulation of the cells at G0/G1 phase while a decrease of cells at S phase;Semi-quantitative RT-PCR detection revealed that the expression of p21 WAF1mRNA was upregulated remarkably in the cells treated with SAHA.Conclusion SAHA could induce differentiation of human HCC SMMC-7721 cells inhibiting enzymatic activity of HDAC,upregulating the expression of p21 WAFlmRNA as well as causing arrest of HCC cells at G0/G1 phase.

Objective:To observe the influence of isehemia-reperfusion(I/R)on hepatoma growth and on the expression of genes associated with tumor metastasis and recurrence(VEGF and MMP-9)in the adjacent tissues of cancer in nude mice. Methods:BALB/c nude mouse model bearing Hep3B-tumor in the liver was established and the model mice were evenly randomly into 5 groups:sham group and ischemia/reperfusion 1 h,6 h,5 d,and 7 d groups(n=8).I/R models were established by blocking porta hepatic;the sham group underwent the same treatment as the I/R model group except for blocking of porta hepatic.ALT and AST were detected in I/R 1 h and 6 h groups.Real-time-PCR was employed to detect the change of VEGF and MMP-9 in the adjacent tissues of cancer and the results were compared with that of the control group(n=6). Histopathological changes of liver were studied by H-E staining and necrotic areas were calculated in I/R 5 d and 7 d groups (n=6).The remnant tumor bearing mice were sacrificed 2 weeks after I/R to measure the volume and mass of the tumors. Results:Two weeks later,the tumor volume and mass in I/R group were increased compared with those in the sham group ([209.6?25.74]mm~3 vs[330.6?32.01]mm~3,[0.214?0.036]g vs[0.374?0.045]g,P
