The study was aimed to explore the relationship between infection of Helicobacter Pylorus (H. Pylorus) and etiology of idiopathic thrombocytopenic purpura (ITP) and evaluate whether H. Pylorus eradication can increase platelet count in patients with ITP. The data-bases of cqvip, Wanfang, TsingHua TongFang, CNKI and PubMed were searched, inclusion and exclusion criteria and heterogeneity test were determined. The studies of H. Pylorus infection and ITP were investigated with fixed effect mode Meta-analysis. Relationship between H. Pylorus infection and etiology of ITP, H. Pylorus eradication and curative effect of ITP were comprehensively and quantitatively evaluated. OR > 1 indicated that factor of exposure was the risk factor of disease; OR < 1 suggested that factor of exposure was the protective factor of disease; OR = 1 revealed that there were no correlation between factor of exposure and diseases. 95%CI was the confidence interval of total OR. The results showed that a total of 211 cases and 210 controls from 5 studies was included to evaluate the exposure of H. Pylorus between ITP patients and controls, the pooled OR was 1.73 (95%CI = 1.12 - 2.67); a total of 458 cases and 305 controls from 13 studies was included to evaluate the relationship between H. Pylorus eradication and curative effect of ITP, the pooled OR was 6.53 (95%CI = 4.44 - 9.61). It is concluded that H. Pylorus infection plays a role in the etiology of ITP. Eradication of H. Pylorus increases platelet count in patients with ITP. H. Pylorus eradication can be used as the first line measure to treat H. Pylorus-positive ITP.

Objective To investigate the CT and MRI features and morphology classification of intraductal papillary mucinous neoplasm of the bile duct (IPMN-B).Methods A total of 18 patients with IPMN-B proved by pathology were retrospectively analyzed.Out of 18 patients,16 patients underwent enhanced and non-enhanced CT,13 underwent contrast enhanced MR,and 11 out of 13 underwent both CT and MRI.IPMN-B was classified into 4 types:typical IPMN-B,cystic-forming IPMN-B,non-tumor IPMN-B and invasive IPMN-B,according to imaging findings and gross pathological findings.Results Typical IPMN-B (9 cases):tumors were distributed along the bile ducts,both upstream and downstream bile ducts were obviously dilated.Cystic-forming IPMN-B (5 cases):single or multiple tumors were found in aneurysmal dilatation of bile ducts.Non-tumor 1PMN-B (2 cases):no mass was found in the widely dilated bile ducts with smooth bile duct wall.Invasive IPMN-B (2 cases):tumors protruded into the dilated bile ducts causing jagged wall of bile duct,with accompanied abnormal density or signal intensity outside the bile ducts.Bile duct dilatations were shown in all 18 cases,and tumors were shown in 16 cases.In 2 cases no mass was displayed in widely dilated bile ducts.CT density of the tumor was lower than that of liver parenchyma,and higher than that of the bile and intraductal mucin.Signal intensity of the tumor was higher than that of stones,and lower than that of bile and intraductal mucin at MR T2WI.All tumors showed high intensity on DWI.Tumors showed mild to moderate enhancement after injection of contrast agent,CT density or signal intensity of the tumors were lower than that of the liver parenchyma during all three phases of contrast-enhanced CT or MRI.Conclusion IPMN-B has some specific CT and MR imaging features,which are helpful for the diagnosis and classification of IPMN-B.

Objective To observe the protective function of recombinant human thioredoxin(TRX) on HeLa cell injury induced by Coxsackie virus 3m(CVB3m) and to study the inhibiting effect of TRX on viral replication. Methods We infected HeLa cells with 10TCID50 CVB3m and then protected these cells with TRX (2,5,10 mg/L). The protective group of TRX, viral group, control group of TRX, and normal control group were included. Six parallel wells were set up in each group. The cell growth was observed by methyl thiazolyl tetrazolium(MTT) and contrast phase microscope. Results The results of contrast phase microscope revealed that HeLa cells were arranged tightly and polygon in normal control group; untightly, became circle and abscission in viral group; HeLa cells morphous improved by increasing TRX concentration in TRX protective group(2,5,10mg/L). MTT results of the inhibitory ratio on cell growth of TRX(2,5,10 mg/L) control group(1.2%,2.9%,6.3%) were compared with normal control group(0), there was no significant difference(all P > 0.05); and while the inhibitory ratio on cell growth of TRX(2,5,10 mg/L) protective group(32.0%,28.0%,27.0%) was compared with virus infective group(51.7%), there was a significant difference (all P < 0.05). The inhibition study of viral replication showed that compared the inhibitory ratio on cell growth of TRX(2,5,10 mg/L) protective group(26.0%,27.0%, 10.9%) with virus infective group(60.0%), there was a significant difference(all P < 0.05). In the protective groups, there was a significant difference (all P < 0.05) between low dose groups(2,5 mg/L) and high dose groups( 10 mg/L). Conclusions The recombinant TRX(2,5,10 mg/L) may alleviate HeLa cell's injury induced by virus and the construct has no significant toxicity. TRX(2,5,10 mg/L) is effective in inhibiting virus CVB3m replication.

OBJECTIVETo explore the effects of high dose glycosides of Tripterygium wilfordii Hook. f (GTW) on the fertility of young rats.

METHODSFifty female SD young rats and 50 male SD young rats were randomly divided into the blank group and the GTW group, 25 in each. GTW was given at the daily dose of 9 mg/kg. After 12 weeks of medication, the male rats were caged together with healthy adult female rats in the ratio of 1:1. The female rats were caged together with healthy adult male rats in the ratio of 2:1. The cage process lasted for two weeks, totally for three times. The pregnant rate of female rats and the survival rate of baby rats were then observed.

RESULTSThere was no significant difference in the pregnant rate or the survival rate of baby rats in the GTW group.

CONCLUSIONHigh dose GTW showed no obvious effects on the fertility of adult rats or the growth and development of new born rats.

italic>Ardisia crispa (Thunb.) A. DC. is a traditional Miao medicinal herb with significant therapeutic effects in the treatment of sore throat, tonsillitis, edema of nephritis and bruising and rheumatism, etc. Ardisia crispa var. amplifolia and Ardisia crispa var. dielsii are varieties of A. crispa. A. crispa var. amplifolia and A. crispa var. dielsii are controversial in terms of species evolutionary relationships and taxonomic identification. In this study, we sequenced the whole genome sequences of A. crispa var. amplifolia and A. crispa var. dielsii chloroplasts using Illumina platform, assembled, annotated and characterized them, compared the structural features and degree of variation among chloroplast genomes using bioinformatics methods, and also downloaded constructing phylogenetic trees to analyze the phylogenetic relationships of chloroplasts in Primulaceae and Myrsinaceae using whole genome sequence information. The results showed that the complete chloroplast genome sequences of A. crispa var. amplifolia and A. crispa var. dielsii were 156 749 bp and 156 748 bp in length, with 132 genes annotated, including 87 protein-coding genes; the codon preference of A/U was greater than that of G/C; The differences in the coding regions of rps15 and rpoB genes in the comparative genome analysis can be used as loci for molecular identification of the two species; the differences in the coding regions of ycf1, ycf2, rpoC1, ycf3, petD and rpl16 genes in the chloroplast genome compared with those of the same genus can be used as loci for identification of the genus. In the phylogenetic results, A. crispa var. amplifolia and A. crispa var. dielsii were clustered together with 100% support, indicating that they are closely related. In this research, we analyzed the chloroplast genome structure and phylogenetic relationships of A. crispa var. amplifolia and A. crispa var. dielsii, providing an important theoretical basis for their molecular identification, genetic variation, breeding and phylogenetic analysis.
