1.Role of microRNA in Regulation of Hepatic Stellate Cell Biological Behavior in Liver Fibrogenesis
Chinese Journal of Gastroenterology 2015;(9):563-566
Liver fibrosis is a repair response to chronic liver injury caused by liver metabolic disorders due to many injury factors. Hepatic stellate cell(HSC)activation and proliferation play an important role in the pathogenesis of liver fibrosis. In recent years,studies showed that microRNAs(miRNA)are involved in signal transduction pathways related with HSC activation and proliferation. This article reviewed the role of miRNA in regulation of HSC biological behavior in liver fibrogenesis.

Objectives To study the effect of ubiquitin proteasome inhibitor bortezomib on apoptosis and Caspase-3 expression in human umbilical arterial vascular smooth muscle cells. Methods Human umbilical artery vascular smooth muscle cells were cultured in vitro. Different doses of bortezomib (0, 4, 10, 40nmol/L) were used to treat cell. Cell proliferation activity were detected by using CCK8 method. Western Blot assay was used to measure the expression of Pro-caspase-3 and Cleaved-PARP protein. Morphology of cells in different groups are observed by confocal microscopy and apoptosis rate were detected by flow cytometry analysis. Results Bortezomib inhibits proliferation activity of vascular smooth muscle cells. With increasing of drug concentration and treating time, cell viability are reduced (P < 0.01). Cells treated with different concentrations bortezomib for 48 h showed increased apoptosis rate (P < 0.01), decreased pro-caspase-3 protein expression and increased cleaved-PARP protein expression (P < 0.01). Laser confocal microscope found that with the increase of drug concentration, the number of apoptotic cells showed an upward trend under per high-power vision. Conclusion The ubiquitin proteasome inhibitor bortezomib may decrease the expression of pro-caspase-3 and increase Cleaved-PARP expression in human umbilical artery vascular smooth muscle cells. Additionally , it could induce apoptosis in a dose-dependent manner.

Objective To understand the health effects and indoor air pollution caused by house decoration in Shizuichan city, Ningxia province. Methods 67 households which were newly decorated were chosen in the different districts of the city. 15days, one month, two months, three months, five months, six months after the decoration finished, formaldehyde, ammonia, benzene, radon in the indoor air were monitored and the questionnaire investigation was conducted. Results After two months, ammonia concentration reached the national standard limit. After 15 days, one month, two months, the rates of exceed limit of formaldehyde were 74.62%, 65.15% and 65.67% respectively, after 3 months ( in June), it was 90.62% and after 6 months, it was 71.21%. After 6 months, benzene concentration decreased slowly. The prevalence rates of throat, eye stimulation, fatigue and so on increased as the pollutants level increased. Conclusion In the investigated city, 6 months after the decoration finished, the indoor air pollution was still serious, which indicates it is not safe to move into those newly decorated rooms, even if after 6 months.

Objective To select excellent tomato mutants by space treatment and to cultivate directly new varieties for production application and good seed resource.Methods Seeds of tomato cultivar were carried into space by scientific experiment recoverable satellite.The main agricultural characters of tomato mutant were observed and analyzed.Results Seeds of determinate growth habit tomato cultivar T10-3-2 were carried into space in 2002 by a recoverable satellite(Shenzhou 4).After cultivation and selection,two tomato variants(H1 and H2) and their offspring populations were obtained in SP2.Variations included quantitative character variations such as maturity,fruit characters and fruit trait,as well as genetic character variations such as changes from determinate growth to indeterminate growth of plant growth habits,and from the no shoulders to the green shoulders of fruits.These two kinds of changes were dominant mutations,and could inherit stably.The research also indicated that variations(amplitude,standard deviation and coefficient of variation) of each generation of two mutants,reduced along with generation increasing.It was showed these characters to be easily stable.Conclusion Tomato seeds loaded on spacecraft can truly form the tomato character variation,and the variation character may be stably inherited.

OBJECTIVE To compare coblation inferior turbinate reduction with inferior turbinectomy by evaluating the differences in the degree ofintraoperative bleeding,degree of post-operative pain,and short-term efficacy in treating inferior turbinate hypertrophy. METHODS Thirty-nine patients were involved in this study. Twenty-five underwent coblation inferior turbinate reduction,and fourteen were treated with inferior turbinectomy with debrider. Subjective symptoms and the inferior turbinate scores were assessed prior to and at 1,3 and 6 months after treatment. In the coblation group,4-6 tunnels were made in each inferior turbinate with Reflex 45 wand under local anesthesia with endoscope. In the control group,debrider was used to remove the hypertropic mucosa of inferior turbinates under endoscope, after which nasal package were used for 2 days to stop the bleeding. RESULTS Coblation inferior turbinate reduction resulted in little intraoperative bleeding and a significant reduction in post-operative pain. At the month 1 follow-up,the severity and the frequency of nasal obstruction were significantly improved in both the coblation and control group. The inferior turbinates were found to have significantly decreased in size in both groups. There was no significant difference between the two groups. At the month 3 follow-up,these improvements were also significant,and the frequency of nasal obstruction was significantly more reduced in the coblation group. The results from the month 6 follow-up conformed to those from the month 3 follow-up. CONCLUSION Coblation inferior turbinectomy is a safe procedure that is easily performed under local anesthsia and results in a significant improvement of nasal obstruction in patients with turbinate hypertrophy. The volumes of the inferior turbinates were alsosignificantly reduced. This procedure is as effective as inferior turbinectomy with debrider. The clinical benefitpersists at 6 months after the procedure.
