Objective:To evaluate effect of telephone follow-up combined with written instruction on compliance and Helicobacterpylori (H.pylori) eradication in patients with H.pylori infection.Methods:A total of 160 H.pylori positive patients were randomly divided into an experimental group and a control group (n=80 in each group).Ml the patients got the guide instruction named the guidance of clinical medication for H.pylori infection patients before the treatment.The patients in the experimental group were added individualized follow-up with telephone.The compliance,eradication ofH.pylori,adverse events,and satisfaction were compared between the 2 groups.Results:The eradication rate of H.pylori in the perprotocol analysis for the experimental group and control group were 64.4％ (47/73) and 56.5％(35/62),respectively (P=0.380),while in the intention-to-treat analysis,the rates were 58.8％ (47/80) and 43.8％ (35/80,P=0.082),respectively.The compliance rate in the experimental group was significantly higher than that in the control group (91.3％ vs 77.5％,P＜0.05).There was significant difference in patients' satisfaction in good ones (75.3％ vs 51.6％) and poor ones (5.5％ vs 21.0％) between the 2 groups (P＜0.05).There were 11 patients in the experimental group and 36 patients in the control group,who appeared adverse reactions such as nausea,bad breath,abdominal distention,poor appetite,and defecation habit change during the process of eradicating H.pylori,but the occurrence rate in the experimental group was obviously lower than that in the control group (15.1％ vs 58.1％,P＜0.05).Conclusion:The telephone follow-up cannot increase the H.pylori eradication rate,but it can improve compliance and satisfaction for the patients and relieve adverse effects.

Background and purpose:miR-101 has been reported to be down-regulated in gastric cancer, colorectal cancer, breast cancer as well as prostate cancer acting as a tumor suppressor gene. However, its function in ovarian cancer is still unknown. The aim of this study was to investigate whether miR-101 can suppress cell growth and invasion of ovarian cancer cells by targeting DNMT3A, so as to reveal molecular mechanism to inhibit ovarian cancer. Methods:Quantitative real-time palymerase chain reaction (qRT-PCR) method was employed to detect the expression of miR-101 in ovarian cancer and cancer adjacent normal ovarian tissues. SKOV3 cells were transfected with miR-101 mimics, and DNMT3A siRNA was transfected as a positive control. Then Western blot was used to detect the expres-sion of DNMT3A protein regulated by miR-101 in SKOV3 cells. The growth and invasion ability of SKOV3 cells were evaluated by MTT and Transwell invasion assays.Results:qRT-PCR showed that miR-101 was down-regulated in ovarian cancer tissues. Western blot showed that the level of DNMT3A protein was inhibited by restored miR-101 or knock-down of DNMT3A in SKOV3 cells. Following transfection of miR-101 mimics or knock-down of DNMT3A for 48, 72 and 96 h respectively, MTT assay showed that theD values were signiifcantly lower than the control group, (P<0.05). After transfection of miR-101 mimics or knock-down of DNMT3A for 36 h, Transwell invasion assay showed that the numbers of cells through the basement membrane was (105±7) and (107±13), respectively, which are signiifcantly different from the control group (213±11), indicating invasion of SKOV3 cells signiifcantly slowed down (P<0.05).Conclusion:miR-101 suppresses cell growth and invasion by targeting DNMT3A in ovarian cancer.
