Objective To investigate the myocardial remodeling and cardiac function effects of metoprolol combined Xinshuaining mixture for treating chronic heart failure.Methods One hundred and seventy patients with chronic heart failure was equally divided into treatment group and control group of 85 cases each,accorded to the random principle of parallelism,both groups were given conventional treatment based on metoprolol,the treatment group was added Xinshuaining mixture.Results After treatment,the effective rate in the treatment group was 95.3 ％(81/85),so that was 81.2％(69/85) in the control group,there was significant difference (P ＜ 0.05).After treatment,the level of left ventricular end-systolic volume (LVESV),left ventricular end-diastolic volume (LVEDV),heart rate (HR) in treatment group were significantly lower than those in control group [(41.36 ±7.11) ml/m2 vs.(44.32 ±6.26) ml/m2,(46.28 ± 7.56) ml/m2 vs.(55.69 ± 8.12) ml/m2,(72.25 ± 3.62) bpm vs.(78.36 ± 3.44) bpm],while the level of left ventricular ejection fraction (LVEF) and 6-minute walk test distance were significantly higher [(56.48 ±8.00)％ vs.(35.16 ± 8.21)％,(566.68 ±51.86) m vs.(476.88 ±50.99) m],there were significant differeces (P ＜ 0.05).After followed up for 3 months,the incidence of cardiac adverse reactions in treatment group was significantly lower than that in control group [3.5％ (3/85)vs.11.8％ (10/85)] (P ＜ 0.05).Conclusions Metoprolol combined Xinshuaining mixture for treating chronic heart failure can improve cardiac remodeling and heart function,thereby improve the prognosis of efficacy.While its better security should be widely applied.

BACKGROUND:During in vitro culture, dental folicle cels are easy to loss self-renewal capacity and become aging, and they are also very difficult to be purified and amplified in quantity, which limits the application of dental folicle cels in periodontal tissue engineering. OBJECTIVE:To study the osteogenic effect of immortalized rat dental folicle cels. METHODS:pSSR69-pAmpho plasmids containing SV40T-Ag were used to transfect 293 cels. Rat dental folicle cels were transfected with virus supernatant and screened by hygromycin to establish immortalized rat dental folicle cels (experimental group). Untransfected cels served as controls. RT-PCR was used to detect the osteogenic related factors (alkaline phosphatase, osteocalcin, bone morphogenetic protein 2, and Runx2) in the experimental group and control group. RESULTS AND CONCLUSION:The results showed no statistical differences between the experimental group and the control group in the expressions of alkaline phosphatase, bone morphogenetic protein 2 and Runx2 (P > 0.05). The expression of osteocalcin was significantly higher in the experimental group than the control group (P < 0.05). These findings suggest that in the late osteogenesis differentiation, immortalized rat dental folicle cels may promote the secretion of osteocalcin and then make osteoblasts early entry into the bone calcification stage.

A total of 21 papers about topical use of triamcinolone in the treatment of oral diseases were retrieved.1 7 of the 21 papers were about the treatment of oral lichen planus,3 were about recurrent aphthous ulcer and 1 was about Behcet's Syndrome.Topical use of triamcin-olone,either used alone or combined with other drugs,was effective in the treatment of oral lichen planus,recurrent aphthous ulcer and Beh-cet's Syndrome.No adverse drug reaction happened when triamcinolone was used in the patients after a short time application,while it hap-pened in the patients after prolonged-use.It may be also effective in the treatment of other allergy or immune dysfunction related oral mucosal diseases,of which more research should be carried out.

OBJECTIVE:To establish RP-HPLC combined with solid phase extraction method to determine the plasma concentration of lansoprazole.METHODS:The sample was extracted by solid phase extraction in darkness.RP-HPLC was applied using Venusil XBP-C18(200 mm?4.6 mm,5 ?m) column.The mobile phase consisted of acetonitrile-water(32:68,pH value adjusted to 7.6 with 1% ammonia water) and flow rate was 1.0 mL?min-1.The detection wavelength was set at 284 nm and column temperature was set at room temperature.RESULTS:The linear range of lansoprazole was 10～2 500 ng?mL-1(r=0.999 9) with mean recovery of 100.93%.The RSD of intra-day and inter-day were both less than 10%.CONCLUSION:The method is sensitive,convenient and rapid for the determination of lansoprazole concentration in plasma.

Objective To analyse the expression and clinical significance of 12 kinds of microRNAs (miR) in patients with ovarian cancer using public gene expression databases. Methods The microRNA expression data were screened in dataset GSE14407 and TCGA database, then 12 kinds of microRNAs were obtained including miR-10B, miR-1244, miR-622, miR-21, miR-503, Let-7D, miR-155, miR-30C, miR-17, miR-101-1, miR-186 and miR-770. The expression data of these 12 kinds of microRNAs were compared and identified to find the differential ones between normal tissue and tumors. Data of 505 ovary cancer patients were divided into two groups by age, tumor grade, clinical stage, disease location, tumor residual and microRNA expression. Kaplan-Meier survival analysis and Cox multivariate analysis were used to compare the overall survival of ovary cancer patients between two groups. Results Compared with ovary cancer, the expression levels of Let-7D and miR-101-1 were higher, but the expression levels of miR-155 and miR-770 were decreased, in adjacent tissue of ovary tumor (P<0.05). The Kaplan-Meier survival analysis result showed that lower survival rates were found in patients with age≥59 years, clinical stage (Ⅲ+Ⅳ) and lower Let-7D expression (P<0.05). The multivariate Cox regression analysis showed that the decreased expression level of Let-7D was the independent risk factor for the prognosis of ovarian cancer. Conclusion The expression of Let-7D is correlated with the prognosis of ovarian cancer, which is the independent biomarker to predict prognosis of ovarian cancer.

Liver transplantation is a valid treatment option for select patients with Hepatocellular Carcinoma HCC and end-stage liver disease. However, in approximately 20% of patients, recurrent HCC is the rate-limiting factor for longterm survival. Despite identification of clinical parameters that may stratify patients at high risk and exhaustive preoperative staging, cancer recurrence is likely the result of microscopic extrahepatic disease. With a desperate donor organ shortage, locoregional ablation techniques and resection are being employed in patients on the waiting list to serve as a bridge to OLT. Further more, some have advocated aggressive surgical resection of isolated metastasis in both the liver and extrahepatic viscera. Whether these creative strategies confer a survival advantage is unknown, requiring longterm follow-up to determine their efficacy.

Vildagliptin,a dipeptidyl peptidase-4 (DPP-4) inhibitor,is always used in combination with metformin.Data from multiple clinical trials showed that vildagliptin and metformin combination therapy can improve HbA1c,fasting blood glucose,and postprandial blood glucose without weight gain,good gastrointestinal (GI)tolerance,and no increase in the incidence of hypoglycemia.Vildagliptin increases plasma levels of glucagon-like peptide-1 ( GLP-1 ).When glucose levels are above normal fasting levels,enhanced GLP-1 levels stimulate insulin secretion.Mefformin has been shown to increase insulin sensitivity and inhibit hepatic glucose production.The effect of vildagliptin to increase plasma levels of intact GLP-1 was enhanced in patients receiving concomitant metformin.
