Objective To study the role of tumor necrosis factor-alpha (TNF-α) and transforming growth factor-beta (TGF-β) in CTD-IDL. Methods mRNAs were extracted from lung tissues and perip-heral blood mononaclear cells (PBMCs) of CTD-ILD patients. RT-PCR was deployed to detect the percentages of TNF-α mRNA, TGF-β mRNAs; and the percentage of TNF-α, TGF-β and fibrosing parameters (hyaluronic acid, HA) was tested in serum by ELISA. The relationship between above laboratory data and image as well as pathological characteristics were analyzed. Results The percentage of TGF-β mRNA in lung tissue and PBMCs. As well as the serum TGF-β and HA increased significantly in those with interstitial lung diseases. On the other hand, the percentage of TNF-α mRNA of these patients did not increase in lung tissues and PBMCs. Conclusion TGF-β plays a role in lung interstitial fibrosis. It may be helpful to understand the degree of fibrosis in lung tissue by detecting lung tissue/PBMCs TGF-β mRNA, serum TGF-β and other fibrosis indicators.

Objective To observe the expressions of stem cell factor(SCF) and macrophage colony-stimulating factor(M-CSF) in bronchoaveolar lavage fluid(BALF) of asthmatic mouse,and the effect of bacillus calmette-guerin(BCG) intervention on them.Methods Thirty Kunming rats were randomly divided into asthmatic group,BCG intervention group and control group,each group had 10 rats.Mice were sensitized and challenged with ovalbumin (OVA) to establish asthmatic model.Asthmatic mice were injected intradermally with BCG on 7,3,1 d before sensitization.After 24 h of last challenge,BALF were collected.The total cells and eosinophils(EOS) were counted in the BALF.The SCF and M-CSF levels of BALF were determined by enzyme-linked immunosorbent assay(ELISA).Results The number of total cells and EOS [(27.06?4.25)?107 L-1,(7.58?1.30)?107 L-1]in BALF in asthmatic mice were more than those in control group[(4.93?1.43)?107 L-1,0](Pa0.05).The M-CSF level also increased noticeably in asthmatic mice[(204.30?10.39) ng/L] compared with the control group[(181.33?8.63) ng/L](P

Objective To investigate the association between hepatic fibrosis and anti-neutrophil cytoplasmic antibodies (ANCA)in the patients with schistosomiasis. Methods Totally 145 schistosomiasis patients confirmed by Jingzhou First Peo-ple's Hospital during the period of February 2014 to June 2016 were randomly selected as an experimental group,and 100 healthy people during the same period were randomly selected as a control group. The serum samples of the two groups were col-lected and the level of ANCA was detected by indirect immunofluorescence,and the levels of hyaluronic acid,laminin,procol-lagen type Ⅲ,and collagen type Ⅳ were detected by radioimmunoassay. The levels of the above indexes of the two groups were compared. Results The positive rate of ANCA was 28.96%(42/145)in the experimental group and 1.00%(1/100)in the healthy control group,and the difference between them was statistically significant(P < 0.05). The levels of hyaluronic acid, laminin,procollagen type Ⅲ and collagen type Ⅳ in the experimental group were significantly higher than those in the control group,and the differences were statistically significant(all P < 0.05),and the proportions of those with abnormal levels of hyal-uronic acid,laminin,procollagen type Ⅲ and collagen type IV in the experimental group were significantly higher than those in the control group,and the differences were statistically significant(all P < 0.05). In the experimental group,among the 42 pa-tients with ANCA positives,the proportions of those with abnormal levels of hyaluronic acid and laminin were significantly high-er than the proportions of those with ANCA negatives,and in the former,the levels of the four indicators of liver fibrosis were all higher than the normal values,and the average levels of hyaluronic acid and laminin in the patients with ANCA positives were significantly higher than those in the patients with ANCA negatives(all P < 0.05). Conclusion The patients with schistosomia-sis hepatic fibrosis could be positive for the autoimmune antibody ANCA,and ANCA may be associated with the autoimmune process of liver fibrosis.

Objective To investigate the gene-expression profile in kidney of rats during late sepsis (24hours) by using microarray technology in order to offer some clue to revealing the pathogenetic mechanism of sepsis at gene level. Method A total of 30 Wistar rats were selected and divided into model group and control group randomly(random number). The rats of control group were sham operated and the rats of model group received cecal ligature and puncture (CLP) operation. The biomarkers of renal function were assayed and the histopathological changes of kidney in rats were observed under transmission electron microscope 24 hours after operation. Gene chips containing 22 107 rat-genes cDNA were used to exmine gene-expression in kidney of septic rats to sieve the genes with different expressions with software. Data were analyzed by using SPSS version 11.0 software package.Statistical analyses of two independent samples carried out by using t -test. Results Compared with the control group, the levels of blood urea nitrogen (BUN) and creatinine (Cr) of sepsis group were higher (P ＜ 0.01 ). The histopathological changes in kidney of rats demonstrated the establishment of sepsis model successful 24 hours later.Compared with the control group, there were 325 genes with differential expression in model group. Among the known-functional genes, there were 100 up-regulated and 64 down-regulated. Sorted by biological function, the genes were mainly related to metabolism, immunoresponse, cellular signal transduction, apoptosis, ion channel,growth factor and so on. Conclusions A sequence of genes expressed differentially in kidney of rats with late sepsis. Microarray technology played an important role in the research into sepsis mechanisms.

Intestinal schistosomiasis is a kind of intravascular parasitic diseases, and chronic inflammation of colon is one of the basic pathological changes of the sickness.However, the mechanism of caveolin-1 and tight junction proteins in the pathogenesis of intestinal schistosomiasis is still unclear.Aims: To study the expressions and significances of caveolin-1 and tight junction protein occludin, claudin-1 in schistosomiasis colitis in mice.Methods: Forty BALB/c male mice were randomly divided into control group and infection group.Schistosomiasis colitis model was established by placing 40 Schistosoma Japonicum cercarie on the abdomen.Mice were sacrificed after 8 weeks.HE staining was performed.The permeability of intestinal vascular endothelium was detected by Evans blue method.The leukocyte counts in peritoneal lavage fluid were measured.qPCR was used to determine the mRNA expressions of caveolin-1, occludin, claudin-1 and eNOS in colon tissue.Western blotting and immunohistochemistry were used to detect the protein expressions of caveolin-1 and occludin.Results: Large number of egg granuloma was observed in colon submucosa and accompanied by extensive inflammatory cells infiltration in infection group.Compared with control group, content of Evans blue and leukocyte counts in peritoneal lavage fluid were significantly increased (P<0.05);mRNA expressions of caveolin-1, occludin, claudin-1 were significantly decreased (P<0.01);protein expressions and positivity rates of caveolin-1 and occludin were significantly decreased in infection group (P<0.05).Conclusions: Down-regulation of expressions of caveolin-1, occludin and claudin-1 can induce leukocyte accumulation via increasing the permeability of intestinal vascular endothelial cells, thereby involving in the development of schistosomiasis colitis.
