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.

Objective To explore the epidemical pattern of acute schistosomiasis in Poyang Lake area so as to provide the scientific evidence for control-strategy-making. Methods The data of acute schistosomiasis in 12 counties along Poyang Lake from 1960 to 2007, including the data of 2 special investigations from 1982 to 1984 and from 1987 to 1989 were collected and analyzed with the retrospective investigation methods. Results There were 29 864 cases of acute schistosomiasis in 12 counties of Poyang Lake area from 1960 to 2007, accounting for 85.5% of the total acute schistosomiasis cases of Jiangxi Province. The largest number of cases existed in Yugan County, accounting for 18. 7%. The peak of acute schistosomiasis prevalence was in 1987 with 2 088 cases. However, the case of acute schistosomiasis declined significantly, keeping at a low level, since 1990. During the 2 special investigations, the people whose age were lower than 30 years old, were the susceptible populations of acute schistosomiasis (86. 1% and 82. 9% , respectively) , most of them were peasants and students, and the infection rates were 57. 4% and 21.2%, 61.7% and 21. 8%, respectively. Fishing and swimming were the main infection ways, with the infection rates of 43.0% and 44.9% , respectively. The peak season of infection was from April to October. Conclusions The river bank and continent of Poyang Lake are the main infection areas, the spring and autumn are the main epidemic seasons and the susceptible populations are the peasants, fishmen and young students. It is very important to enhance the comprehensive prevention and treatment measures in the key areas and population for schistosomiasis control.

Objective To investigate the performance of DNA microarray in identifying 6 common Candida spp. and validating ERG11 mutations resulting in fluconazolc-resistance in Candida albicans. Methods Oligonucleotide probes were designed and synthesized targeting the species-specific sequence in the internal transcribed spacer 2 (ITS2) region of rDNA of Candida albicans, Candida tropicalis, Candida glabrata, Candida dubliniensis, Candida parapsilosis and Candida krusei, as well as 6 sequences embracing the following mutations respectively in ERG11 gene leading to fluconazole-resistance, i.c., T541C, A 1090G, C1361T, G1537A, G1547A, and T1559C, then arranged onto a chip. Twelve 50-base-pair oligonucleotides were artificially synthesized based on the above specific sequences, and utilized to hybridize with the DNA microarray. Thirty-lbur Candida strains, including 29 C. albicans, 1 Candida tropicalis, 1 Candida glabrata,1 Candida dubliniensis, 1 Candida parapsilosis and 1 Candida krusei, were detected with microarray. Genomic DNA was extracted from these tested strains and underwent multiple PCR for the amplification of ITS2 region and ERGI 1 gene. Sequencing was performed to analyze the sequence of ERG11 in 29 strains of C. albicans and the results were compared with those of DNA microarray hybridization. Results Multiple PCR successfully produced ITS2 fragment of 307-415 bp from all the 34 strains, as well as ERG11 fragment of 1712 bp from 29 C. albicans strains. DNA microarray hybridization offered the same results in species identification of the 34 strains with their given information, as well as in mutation detection of the 29 strains of C. albicans with ERG11 sequencing results. Also, the 6 synthesized oligonucleotides containing the muta- tions were identified precisely as T541C, A1090G, C1361T, G1537A, G1547A, and T1559C, and the 6 species specific oligonucleotieds were identified correctly as C. albicans, C. tropicalis, C. glabrata, C. dubliniensis, C. parapsilosis and C. krusei Both the sensitivity and the specificity of the microarray were 100%. Conclu- sion DNA microarray is a quite reliable method to identify Candida spp. and fluconazole resistance-associ- ated mutations in the ERG11 gene of C. albicans.

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.
