Background: There is no gold standard for the diagnosis and monitoring of inflammatory bowel disease (IBD).As immune system plays crucial role in the pathogenesis of IBD,some immune-specific serum antibodies are considered to be useful tools for the diagnosis and differential diagnosis of the disease.Aims: To investigate the clinical significance of serum antibodies,including anti-Saccharomyces cerevisiae antibody (ASCA) and perinuclear anti-neutrophil cytoplasmic antibody (pANCA) in IBD.Methods: Serum samples were obtained from 91 consecutive IBD patients from Feb.2015 to May 2016 at the First Affiliated Hospital of Soochow University.Of them,52 were Crohn's disease (CD) and 39 were ulcerative colitis (UC).Serum samples of 36 non-IBD patients were served as controls.ASCA-IgG and ASCA-IgA were detected by ELISA,and pANCA by indirect immunofluorescence assay.Using clinical diagnosis as gold standard,crosstabs statistics was performed to measure the diagnostic accuracy of ASCA and pANCA,and ROC curve,Pearson Chi-square test and Fisher's exact test were employed for analyzing the correlations of these two serum antibodies with IBD,CD,UC,and the location of the disease.Results: Both serum ASCA-IgG and IgA were correlated with CD (AUC=0.626 and 0.614),while UC was correlated with ASCA-IgA only (AUC=0.486).Serum pANCA had relevance to IBD (r=0.342),CD (r=-0.262) and UC (r=0.614);its sensitivity and specificity for IBD and UC were superior to those for CD (P＜0.05).In CD patients,ASCA-IgG was associated with terminal ileal disease (P＜0.05),and pANCA was associated with colonic involvement (P＜0.05).In UC patients,both ASCA-IgG and IgA were correlated with terminal ileal disease (P＜0.05).Conclusions: Serum ASCA and pANCA may be helpful for discrimination between CD and UC when the diagnosis of IBD is established.Furthermore,they are closely associated with the disease location,ASCA is related with the terminal ileal disease and pANCA is related with colonic involvement.

"Treatment after discovery" is the most effective way to prevent and treat AIDS by far.Although Yunnan Province has made remarkable achievements in the three wars of AIDS prevention and control,it faced realistic obstacles of slow updating of knowledge,shortage of full-time medical staff,unstable team and poor trans-provincial treatment system in the implementation of "treatment after discovery".This paper analyzed these obstacles from the perspective of bioethics,reflected the ideological roots of the unfulfilment to the HIV / AIDS population's dignity identify and human rights protection,and further put forward countermeasures and suggestions.

Objective:To explore the level of tibial growth plate chondrocyte mitophagy in young rats with chronic renal failure (CRF) and its effect on chondrocyte apoptosis.Methods:Male 4-week-old Sprague-Dawley rats were randomly divided into two groups according to random number table method: normal control group ( n=20, intragastric administration with distilled water) and CRF group ( n=20, given adenine suspension 150 mg·kg -1·d -1). All the young rats were sacrificed after continuous gavage for 6 weeks. The length of tibia was measured on X ray film, the width of tibia growth plate was measured and compared on histological section, and the apoptosis rate of chondrocytes in growth plate was detected by terminal deoxynucleotidyl transferase-mediated dUTP-biotin nick end labeling (TUNEL) assay. The growth plate chondrocytes of two groups were isolated and cultured to the third generation in vitro, and the apoptosis rate of chondrocytes was detected by TUNEL assay. The co-localization of mitochondria and autophagy lysosomes in chondrocytes was observed by double fluorescence staining. Western blotting was used to detect the level of mitochondrial marker protein translocate of the outer mitochondrial membrane-20 (Tom-20) and autophagy marker light chain-3 protein (LC-3). The mitophagy of growth plate chondrocytes was observed by transmission electron microscope. Results:Compared with the normal control group, the tibia length of CRF group was shorter [(27.32±5.81) mm vs (35.43±3.61) mm, t=5.226, P<0.001], and the relative width of growth plate in histological section was narrower (0.56±0.19 vs 1.00±0.21, t=6.744, P<0.001). The apoptosis rate of chondrocytes in growth plate in CRF group was higher than that in the normal control group (17.2%±4.8% vs 5.1%±3.4%, t=6.505, P<0.001). The apoptosis rate of chondrocytes cultured in vitro in CRF group was higher than that in the normal control group (11.8%±6.2% vs 3.1%±1.2%, t=4.357, P<0.001). The result of double influorescence staining showed that there was co-localization between mitochondria and autophagy lysosomes in CRF group. Western blotting results showed that the levels of LC-3 protein ( t=8.944, P<0.001) and Tom-20 protein ( t=6.708, P<0.001) in CRF group were lower than those in the normal control group. Conclusion:The level of tibial growth plate chondrocyte mitophagy in young rats with CRF increases, which will lead to a decrease in the number of mitochondria, an increase in the apoptosis and a decrease in the number of chondrocytes, and eventually lead to dysplasia of tibia.

OBJECTIVE：To investigate the anti- hepatic fibrosis （HF）effects of Qiwei qinggan powder and explore its possible mechanism. METHODS ：Male Wistar rats were randomly divided into blank group ，HF model group ，Qiwei qinggan powder low-dose，medium-dose and high-dose groups [ 135，270，405 mg/（kg·d），by total amount of crude drugs] ，with 12 rats in each group. Except for blank group ，other groups were given 50％ CCl4-peanut oil solution intragastrically （2 mL/kg，twice a week ，for consecutive 8 weeks） to induce HF model. At same time ， blank group and model group were given constant volume of 0.5％ CMC-Na solution intragastrically ；administration groups were given relevant medicine intragastrically ，once a day ，for consecutive 8 weeks. General situation of rats were observedand liver morphology was observed after last administration and hepatic indexes were detected. The contents of liverfunction indexes （ALT，AST，ALP，HYP）in serum and the expression of α-SMA in hepatic tissue were determined ， and HE and Masson staining were performed to observe the histopathology. Using the difference multiple of expression quantity as the index ，TMT technology was used to screen the differentially expressed protein in medicine group （combining the liver tissue samples of Qiwei qinggan powder groups ）and HF model group. Uniprot-GOA database and KAAS ，KEGG mapper online tools were used to analyze GO and KEGG pathway enrichment. RESULTS ：The rats in the blank group were in good health ；the liver was bright red and smooth ，the liver lobules were intact ，no degeneration and necrosis ，inflammatory cell infiltration or fibrous tissue proliferation was found. Compared with blank group ，the rats in HF model group had poor diet ，depressed spirit ，disordered and lusterless fur ；the liver was dark red or yellow with rough surface ，hard texture ，inflammatory cell infiltration ，fiber tissue destruction ，bridge connection and so on ；the hepatic index ，the contents of liver function indexes and the expression of α-SMA were increased significantly （P＜0.05）. Compared with HF model group ，above symptoms of rats were improved to different extent in different dose groups of Qiwei qinggan powder ；hepatic index in Qiwei qinggan powder low-dose group ，the content of ALP in high-dose group ，the contents of ALT，AST and HYP and the expression of α-SMA in different dose groups were decreased significantly （P＜0.05）. A total of 42 differentially expressed proteins related to HF were screened ，of which 15 were up-regulated and 27 were down-regulated in expression，including fatty acid binding protein 4（FABP4），cholesterol 7α-hydroxylase（CYP7A1）. The results of enrichment analysis showed that the differentially expressed proteins were mainly enriched in extracellular space ，blood particles and other cell parts，involving the molecular functions of oxidoreductase activity and fatty acid binding ，the biological processes of the regulation of heterotypic cell adhesion ，protein activation cascade ，as well as retinol metabolism ，arachidonic acid metabolism ，PPAR and other signal pathway. CONCLUSIONS ：Qiwei qinggan powder can reduce the hepatic index ，ALT，AST，ALP and HYP contents in serum ，down-regulate the expression of α-SMA，improve the degree of inflammation and fibrosis of liver tissue ，and have a certain protective effect on rats. The anti-HF mechanism of it involves multiple targets and signal pathways ，such as FABP 4， CYP7A1 and PPAR.
