Objective To investigate the incidence of cholecystolithiasis in 1iver cirrhosis and analyze its influencing factors and clinical significance. Methods We selected 128 patients with 1iver cirrhosis who were di-agnosed and treated in the First Affiliated Hospital of Henan University of Science and Technology from Oct. 2014 to Aug. 2015 as the observation group. Meanwhile, 140 cases received medical examination served as the control group. The liver cirrhosis group were divided into class A (group A), class B (group B), class C (group C) ac-cording to the Child-Pugh grades. We measured the levels of fasting serum albumin (ALB) and cholecystokinin (CCK) of all subjects. The relationship of cholecystolithiasis in 1iver cirrhosis to gender, liver function Child-Pugh classification, ascites, levels of ALB and CCK was analyzed. Results (1) Univariate analysis revealed: compared with the control group, the incidence of cholecystolithiasis in 1iver cirrhosis group was higher (35.2%vs 8.6%, P<0.05). With increase of the degree of liver damage, the incidence of cholecystolithiasis increased. And the incidence of cholecystolithiasis in group B and group C were both higher than that of group A (group A 22.9% vs group B 35.0%vs group C 50.0%, P<0.05). The incidence of cholecystolithiasis in the 1iver cirrhosis group with ascites was significantly higher than that of the control group (38.6% vs 22.2% vs 8.6%, P < 0.05). With increase of the degree of liver damage, the level of ALB in liver cirrhosis group decreased compared with the control group (P<0.05), while the level of CCK was obviously higher than that of the control group (P < 0.05). The morbidity rate did not differ between the males and females with cirrhosis (P>0.05). (2) Multiple Logistic regression analysis re-vealed that the level of ALB is the main influencing factor (P<0.05). Other factors were not statistically significant. Conclusion Cholecystolithiasis frequently occurs in patients with liver cirrhosis, which has no correlation with the gender of patient, but it correlates with liver function, ascites, the levels of ALB and CCK. Among of them, the level of ALB is the main influencing factor.

Aim To investigate the effects of isoliquiri-tigenin ( ISL) on anti-angiogenesis both in vitro and in vivo and its mechanisms. Methods We assessed the antiangiogenic activities of ISL on proliferation viabili-ty, migration and tube formation of human microvascu-lar endothelial cell line-1 (HMEC-1) in vitro. The cell proliferation viability was assessed using the Sulforho-damine B ( SRB ) assay. Modified Boyden Transwell chamber assay was done to study the effect of ISL on HMEC-1 cells migration. 2′, 7′-dichlorofluorescein di-acetate ( DCFH-DA) was used to measure the levels of intracellular reactive oxygen species ( ROS ) , which was induced by VEGF. Metalloproteinase-2 ( MMP-2 ) and metalloproteinase-9 ( MMP-9 ) expressions by HMEC-1 cells were assessed through gelatin zymogra-phy assay. HMEC-1 cells cycle was detected by flow cytometry. Moreover, we investigated the in vivo anti-angiogenic activity of ISL on chicken embryos nap al-lantoic membrane model ( CAM ) . Results ISL con-centration-dependently inhibited the growth of HMEC-1 cells as well as SW620 and A549 cells. ISL signifi-cantly and concentration-dependently suppressed the migration activity of HMEC-1 cells. Tube sample struc-ture formation further confirmed the effect of ISL on an-ti-angiogenesis. Moreover, ISL also inhibited intracel-lular ROS level, MMP-2 and MMP-9 expression by HMEC-1 cells. ISL induced endothelial cell apoptosis at a low concentration ( ISL 12 . 5 μmol · L-1 ) and blocked the cells in S phase of mitosis at higher con-centrations ( ISL 25~100 μmol·L-1 ) . Furthermore, ISL distinctly inhibited the angiogenesis of chick em-bryos in vivo. Conclusions ISL has anti-tumor and angiogenesis effects on HMEC-1 cells. The mechanism may be related to intracellular ROS scavenging and ap-optosis induction of HMEC-1 cells.

OBJECTIVE To invesigate the prevalence of SHV-producing Enterobacteriaceae isolates in Hunan Province and identify the subtype of SHV encoding gene and the epidemiological aspect of SHV-producing isolates. METHODS Isolates were collected and identified as well as subjected to ESBLs detection.PCR and DNA sequencing were used to determine the genotype of SHV enzymes.The homology of SHV-producing strains were detected by RAPD. RESULTS Twenty-six of 171 Enterobacteriaceae isolates were confirmed to produce blaSHV genes,and 5 subtypes of SHV-type ?-lactamases were determined,including 9 strains of SHV-28,7 strains of SHV-12,7 strains of SHV-1,2 strains of SHV-11 and 1 strain of SHV-5.There were 6 RAPD types in 19 isolates of SHV-producing Klebsiella pneumoniae,5 RAPD types in 5 isolates of SHV-producing Enterobacter cloacae. CONCLUSIONS SHV-12 is the predominant genotype of SHV ESBLs producing Enterobacteriaceae in Hunan Province,and clone spread has played a certain role in SHV-type ?-lactamase producing K.pneumoniae.SHV ESBLs are not found in Escherichia coli.
