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.

Objective To study the role of hydrogen sulfide (H2S) in the effect of SB203580 on proliferation and apoptosis of hepatic stellate cells and the effects of H2S on expressions of collagenⅠand collagenⅢmRNA in hepatic stel-late cells. Methods There were five groups of HSC-T6 cells in this study including control group (DMEM medium contain-ing10%fetal bovine serum), dimethyl sulfoxide (DMSO) group, sodium hydrosulfide (NaHS)group,SB203580 (SB)group and SB+NaHS group. MTT method was used to detect the cell proliferation and inhibition rate of HSC-T6 cells treated by SB203580 and H2S. The apoptotic rate of HSC-T6 cells was detected by flow cytometry with annexin V-FITC/PI double staining. RT-PCR was used to detect the expressions of collagenⅠand collagenⅢmRNA in HSC-T6. Results The apop-totic rate of HSC-T6 cells was significantly higher in SB group and SB+NaHS group than that of control group, and the rate was significantly higher in SB+NaHS group than that of SB group (P＜0.05). There was no significant difference in the apop-totic rate of HSC-T6 cells between DMSO and NaHS groups than that of control group. The expressions of collagenⅠand col-lagenⅢmRNA were found in five groups of cells. There was a higher expression of collagenⅠand collagenⅢmRNA in NaHS group than that of control group (P＜0.05). The expressions of collagenⅠand collagenⅢmRNA were significantly lower in SB group and SB+NaHS group than those of control group and NaHS group (P＜0.05). Conclusion H2S activated P38MAPK signal pathway. And P38MAPK was specifically blocked by SB203580 in HSC-T6 cells, which inhibited the cell proliferation stimulated by H2S and promoted the apoptosis.

Objective To investigate the clinical curative effect and safety of ultrasound-guided lauromacrogol injection and ethanol injection in treating hepatic hemangiomas.Methods A total of 60 patients with hepatic hemangioma were randomly and equally divided into lauromacrogol group (n=30) and ethanol group (n=30).Ultrasound-guided lauromacrogol injection and ultrasound-guided ethanol injection were performed for the patients of lauromacrogol group and the patients of ethanol group,respectively.The clinical curative effect and the incidence of adverse reaction of the two groups were evaluated,and the results were compared between the two groups.Results No statistically significantly difference in clinical curative effect existed between the two groups (P=0.489,P＞0.05).The incidence of adverse effects in the ethanol group was significantly higher than that in the lauromacrogol group,and the difference was statistically significant (x2=5.963,P=0.03,P＜0.05).Conclusion For the treatment of hepatic hemangiomas,ultrasound-guided lauromacrogol injection carries quite the same curative effect as ultrasound-guided ethanol injection does,but lauromacrogol injection has less untoward effects and lower pain rate,besides,injection of lauromacrogol can be well tolerated by the patients.Therefore,the method of ultrasound-guided lauromacrogol injection is worthy of clinical application.

OBJECTIVETo investigate the role of the PI3K/Akt signaling pathway in hydrogen sulfide-induced alterations in expression of collagen I and collagen III in hepatic stellate cells.

METHODSIn vitro cultured rat hepatic stellate cells (HSC-T6) were treated with hydrogen sulfide, or left untreated for use as controls, and divided into groups for treatment with different inhibitors for the various factors involved in the PI3K/Akt signaling pathway. Reverse transcription-PCR was used to measure Collagen I and collagen III mRNA expression. Western blotting was used to detect the protein expression of PI3K and p-Akt, which are upstream proteins of the PI3K/Akt pathway.

RESULTSCompared with the untreated control cells, the hydrogen sulfide treated cells showed elevated expression of collagen I mRNA (F =14.635, P less than 0.05), collagen III mRNA (F =14.620, P less than 0.05), PI3K protein (F =26.672, P less than 0.05), and p-Akt (F =23.522, P less than 0.05). Compared to the cells treated with hydrogen sulfide alone, the cells treated with the various inhibitors showed lower expression of collagen I mRNA (F =14.635, P less than 0.05), collagen III mRNA (F=14.620, P less than 0.05), PI3K protein (F =26.672, P less than 0.05), and p-Akt protein (F =23.522, P less than 0.05).

CONCLUSIONHydrogen sulfide can activate the PI3K/Akt pathway and elevate the expression of collagen I and collagen III in rat hepatic stellate cells.
