OBJECTIVE:To systematically review the efficacy and safety of Magnesium isoglycyrrhizinate injection versus 4 comnon medicines in the treatment of drug-induced liver damage,and to provide evidence-based reference for clinic treatment. METHODS:Retrieved from PubMed,EMBase,Cochrane Library,CBM,CJFD,Wanfang Database and VIP Database,random-ized controlled trials (RCT) about Magnesium isoglycyrrhizinate injection versus other medicines in the treatment of drug-induced liver damage were enrolled. Meta-analysis was performed by using Rev Man 5.3 software after literature selection,data extract and quality assessment. RESULTS:A total of 13 RCTs were included,involving 1 093 patients. Results of Meta-analysis showed clini-cal effective in magnesium isoglycyrrhizinate group was significantly higher than tiopronin group[RD=0.29,95%CI(0.17,0.42), P<0.001] and diammonium glycyrrhizinate group [RD=0.07,95%CI(0.01,0.12),P=0.02],compared with glutathione group and compound ammonium glycyrrhetate group,there were no significant differences ;incidence of adverse reactions in magnesium iso-glycyrrhizinate group was significantly lower than diammonium glycyrrhizinate group [RD=-0.07,95%CI(-0.11,-0.03),P<0.001] and compound ammonium glycyrrhetate group[RD=-0.21,95%CI(-0.38,-0.04),P=0.02],compared with triopro-nin group and glutathione group,there were no significant differences among 3 groups. CONCLUSIONS:Magnesium isoglycyrrhiz-inate injection has better efficacy and safety than other 4 commons hepatoprotective medicines in the treatment of drug-induced liver damage. Due to the limit of methodological quality,more large-scale and long-term follow-up studies with strict designed are need-ed for the further verification of the conclusion.

OBJECTIVE: To investigate the expression of monocyte chemotactic protein-1 (MCP-1) and its receptor CC chemokine receptor-2 (CCR-2) in coronary atherosclerosis plaques between sidden coronary death (SCD) and non-SCD. Methods The expression levels of MCP-1 and CCR-2 in SCD group, coronary atherosclerosis group (non-SCD), control group (normal coronary artery) were detected by immunohistochemistry. RESULTS: Positive rates of MCP-1 among the three groups were 78%, 47%, and 0%, respectively, with significant expressing differences between each two groups (P<0.05). Positive rates of CCR-2 among three groups were 72%, 47%, and 0%, respectively, with significant expressing differences between the SCD group and coronary atherosclerosis group as well as between the SCD group and control group (P<0.05), but with no significant expressing difference between coronary atherosclerosis group and control group (P>0.05). CONCLUSION Overexpression of MCP-1 and CCR-2 in coronary atherosclerotic plaques is closely correlated with SCD.

OBJECTIVETo analyze the changes of patients with type 2 diabetes in different stages in glucagon (GC) and free fatty acid (FFA) in fasting, OGT and L-Arg experiments, and discusses the role of pancreatic alphabeta cells in diabetes pathogenesis by studying the relations among indexes such as glucagon (GC), free fatty acid (FFA) and blood glucose (BG), insulin, insulin homeostasis model (HOMA) and glucose metabolism hormone secretion curve, in order to provide theoretical basis for the treatment of diabetes.

METHODStudy objects were divided into the T2DM group (45 cases), the IGT group (28 cases) and the NGT group (30 cases) for an OGTT experiment and then an L-Arg experiment on the next day. Under the fasting state, their blood glucose (FBG), insulin (F), glucagon (FGC), free fatty acid (FFA) were detected to calculate HOMA-beta, insulin sensitivity index (ISI) and HOMA-IR of different groups. Meanwhile, efforts were made to calculate different time quantum detected in OGTT and L-Arg experiments and area under the curve AUC(BG), AUC(INS) and AUC(GC).

RESULTObvious overall differences were observed in FFA and FGC of the three groups. FGC of each group was negatively correlated with HOMA-beta and ISI. Among all of the 103 study objects, FGC was positively correlated with FBG and HOMA-IR and negatively correlated with HOMA-beta and ISI, with no correlation with FINS; FFA was positively correlated with FBG, HOMA-IR and negatively correlated with FINS, HOMA-beta, ISI. FGC and FFA were positively correlated in the T2DM group and the IGT group, but with no statistical correlation in the NGT group. The sequence of the three study objects was T2DM > IGR > NGT in AUC(GC) in the OGTT experiment and T2DM > IGR > NGT in in AUC(GC) in the L-Arg experiment, with the significant positive correlation between AUC(GC) and AUC(BG) and significant negative correlation with AUC(INS).

CONCLUSIONGlucagon and free fatty acid of T2DM and IGT patients increased, which was positively correlated with blood glucose and HOMA-IR and negatively correlated with INS, HOMA-beta and ISI. The increase in glucagons of T2DM and IGT patients indicated inappropriate secretion of pancreatic alphabeta cells among patients with type 2 diabetes.

Background:CXC chemokine receptor type 2(CXCR2)is a member of G protein coupled receptor superfamily,and is mainly involved in the growth of tumor,angiogenesis and the pathogenesis of inflammatory diseases. Studies showed that CXCR2 was associated with the pathogenesis of inflammatory bowel disease(IBD),but the exact role has not yet been clarified. It was found that the interaction of interleukin-8(IL-8)with CXCR1 and CXCR2 played an important role in the pathogenesis of IBD. Aims:To investigate the expressions and significance of CXCR2 and IL-8 in patients with IBD. Methods:A total of 121 IBD patients in active stage from October 2013 to December 2014 at Zhongnan Hospital of Wuhan University were enrolled and assigned into Crohn’s disease(CD)group and ulcerative colitis(UC)group. Seventy healthy subjects were served as controls(HC). Expressions of IL-8 mRNA and CXCR2 mRNA in peripheral blood and intestinal mucosal tissue were determined by real-time PCR;expression of CXCR2 protein in intestinal mucosal tissue was determined by Western blotting. Results:In peripheral blood,expression of IL-8 mRNA in UC group was significantly higher than that in HC group(P = 0. 017),while expressions of CXCR2 mRNA in CD,UC and HC groups were not significantly different (P = 0. 285). In intestinal mucosal tissue,expressions of IL-8 mRNA in CD,UC and HC groups showed no significant difference(P = 0. 206),while expressions of CXCR2 mRNA in CD and UC groups were significantly higher than that in HC group(P = 0. 002;P < 0. 001),and expression of CXCR2 mRNA in UC group was significantly higher than that in CD group(P = 0. 005);expressions of CXCR2 protein in UC and CD groups were higher than that in HC group(P = 0. 049 P =0. 080). Conclusions:Expressions of CXCR2 mRNA and protein in intestinal mucosal tissue of patients with IBD, especially UC are significantly increased. Down regulation of CXCR2 expression in intestinal mucosa may provide a new target for treatment of UC. IL-8 is significantly highly expressed in peripheral blood of patients with UC,which suggests that IL-8 might be related mainly with UC.

Objective To analyze implementation outcomes of the new health reform policy at a provincial hospital for the past six months.Methods Trend analysis,factor analysis and ratio analysis approaches were used in monthly surveillance,along with comparative study of the data before and after the reform,to probe into impacts of the new policy on hospital operations.Results Medical income increased by 22.09％,mainly contributed by volume growth (22.28％) of medical services; Medical income dropped by 0.16％ due to pricing policy factors; medicine proportion deceased by 4.84％; following the reform,the income per outpatient and inpatient increased by 12.32％ and 5.35％ respectively.Conclusion Following the drug zero profit policy and rise of the charging standards for medical treatment service at the hospital,the growth of total income mainly comes from growing volume of medical services instead of pricing policy factors.The new health reform is conducive to optimizing the hospital's income structure and raising value to doctors' technical service.

Objective To assess the clinical significance of antibodies against cyclic citrullinated peptide(anti - CCP) in a cohort of patients with juvenile idiopathic arthritis (JIA). Methods The anti - CCP was tested by an enzyme linked immunosorbent assay (ELISA) in serum samples from 22 patients with JIA(9 boys, 13 girls), with a mean age of 9.1 years(range 1.1 - 16). As control groups, anti - CCP were also tested in sera of 20 healthy children, and 30 adult patients with rheumatoid arthritis(RA). Results Positive anti - CCP were found in sera of 2 patients with JIA(9.1 %), both with lower titre comparing with those of adult patients with anti - CCP positive. In the control groups, none of healthy children was positive for anti - CCP, but 16/30(53. 3%) adults with RA showed anti - CCP positivity. Conclusion Anti - CCP can be detected in children with JIA, but are less frequently present than in adults with RA, so anti - CCP has limited diagnostic value to JIA.

Objective:To investigate the changes of default network functional connectivity (FC) in resting state of patients with insomnia disorder (ID).Methods:Fifty-six patients with insomnia disorder and fifty healthy controls were recruited. All subjects were assessed with Pittsburgh sleep quality index (PSQI), insomnia severity index (ISI), Epworth sleepiness score (ESS) and Hamilton depression scale (HAMD-17). All subjects were scanned with resting state functional magnetic resonance imaging (rs-fMRI). SPM12 and CONN18b were used to preprocess rs-fMRI data on MATLAB (R2013b).The medial superior frontal gyrus was defined as the seed point, and the differences in the functional connection strength of the two groups of subjects were compared. Pearson correlation analysis was performed between the FC value of the brain area with statistical significance and scores of PSQI and ISI.Results:(1)FC analysis showed that compared with the control group, patients with ID had abnormal default mode network (DMN) connection, as follows: FC of left medial superior frontal gyrus and left central anterior gyrus (MNI: x, y, z=-30, -15, 51) and anterior cingulate gyrus (MNI: x, y, z=-6, 24, 36), FC of right medial forehead between the last gyrus and the left central anterior gyrus (MNI: x, y, z=-48, -6, 48), FC of left anterior cuneiform and the left central back (MNI: x, y, z=-54, -18, 54) and left superior occipital gyrus (MNI: x, y, z=-21, -69, 30), FC of right precuneus and left central posterior gyrus (MNI: x, y, z=-60, -21, 48) was enhanced. The FC of left anterior cuneiform lobe and the right middle frontal gyrus (MNI: x, y, z=42, 33, 42) and the right angular gyrus (MNI: x, y, z=54, -51, 45), FC of right precuneus and left inferior temporal gyrus (MNI: x, y, z=-51, -12, -42) was weakened. (2)With the left medial superior frontal gyrus as the seed point, FC values in anterior cingulate gyrus ( r=0.451, 0.338, both P<0.01) and left anterior central gyrus ( r=0.324, 0.402, both P<0.05) were positively correlated with PSQI and ISI scores. With the right precuneus as the seed point, FC value of left posterior central gyrus was positively correlated with PSQI( r=0.333, P=0.013) and ISI scores( r=0.418, P=0.008), while FC value of left inferior temporal gyrus was negatively correlated with PSQI( r=-0.662, P=0.001) and ISI scores( r=-0.402, P<0.01).With the left precuneus as the seed point, FC value of left superior occipital gyrus was positively correlated with PSQI( r=0.438, P=0.001) and ISI scores( r=0.495, P=0.011). Conclusion:Patients with ID may have changes in the functional connection of multiple networks. The decrease of FC in DMN may be one of the potential causes of insomnia. The increase in FC between DMN and the visuospatial attention network may be the core of the mechanism of damage to the brain function network of insomnia link.
