Objective To analyse the relationship and mechanism between chronic periodontitis (CP) and IgA nephropathy (IgAN) by establishing animal model of chronic periodontitis and IgA nephropathy in SD rats.Methods Eighty health male SD rats were divided into four groups,control group (A,n=20),IgAN group (B,n=20),CP group (C,n=20),CP accompanied with IgAN group (D,n=20).CP model was established by ligating silk suture and besmeared pathogenic bacterium in rats dental cervix.Experimental IgAN model was established by lavage of bovine serum albumin (BSA) and injection of lipopolysaccharide (LPS) and carbon tetrachloride (CCl4).Ten rats were sacrificed in every group at the end of week 8 and 12.The blood,urine,kidney tissue samples were examined.The observation index included proteinuria,kidney and liver function,renal tissue pathology and periodontal tissue pathology.The data were statistically analysed.Results Animal models were established successfully.The levels of Scr and BUN in group A,B,C were not obvious difference,but that in group D was higher than the other third groups at 8 weeks (P ＜ 0.05).The levels of Scr and BUN in group D and group B were significantly higher than that in group A,meanwhile that in group D was significantly higher than that in group B at 12 weeks(P ＜ 0.05).The levels of 24 h urine protein in B,C,D groups were higher than that in group A at 8 weeks(P ＜ 0.05),but at 12 week,that in group D was higher than that in group B and C (P ＜ 0.05).At 8 weeks,glomeruli had little mesangial broadening and renal interstitium had mild hyperplasia of fibrous tissue in group B and D,and that in the group D significantly was heavier than that in group B.The focal varying degrees were glomerular mesangial proliferation hardening,glomerular mesangial broadening,focal segmental sclerosis,and diffuse or focal inflammatory cell infiltration in D group at the end of week 12.The score of PAS between group A and group C had no statistical significance.The scores of PAS in group B and D were higher than that in group A (P ＜ 0.01),and that in group D was higher than that in group B (P ＜ 0.01).Obvious inflammation of periodontal tissue was observed in group C and D,and modified sulcus bleeding index (MBI) were higher than that in group A and B,and MBI in group D was significantly higher than that in group C (P ＜ 0.01).Conclusions The model can be used to research the change of biochemistry and pathology and observe the relationship between chronic periodontitis and IgAN.This study shows that there is relationship between chronic periodontitis and IgAN.Chronic periodontitis maybe make more serious pathology damage in kidney by inflammation mechanism.

Currently, bacterial resistance situation in health care settings is very serious in China, and the prevalence of a variety of common multidrug-resistant bacteria and pan-resistant bacteria are relatively high. Drug-resistant bacteria in Gram-positive bacteria are mainly methicillin resistant Staphylococcus aureus ( MRSA ) and macrolide-resistant Streptococcus, while glycopeptide-resistant enterococci are still at a low level.The clonal distribution of MRSA and mechanisms of Streptococcus resistance in China are different from those in European and American countries.Cephalosporins and quinolones resistance are the marked characteristic of Enterobacteriaceae with a high occurrence over 60%. Carbapenem-resistant Klebsiella pneumoniae shows a rapid upward trend, and producing KPC-2 type carbapenemases is the main mechanism of its resistance.Resistance in Pseudomonas aeruginosa is relatively stable, with resistant rates ranging from 20%to 30%.Multi-drug resistant Acinetobacter baumannii is a big problem in clinic.More than 50% Acinetobacter baumannii strains are resistant to carbapenems and cephalosporins, and tigecycline-resistant Acinetobacter baumannii is increasing.This paper systematically reviews the status and characteristics of bacterial resistance in last five years with referring to the surveillance data of antimicrobial resistance and the findings of related mechanisms.

Objective To investigate the role of Twist and vascular endothelial growth factor (VEGF)in the development of epithelial ovarian cancer and their relationship with clinical pathological features.Methods The expressions of Twist and VEGF were detected by immunohistochemical staining (SP)method in 80 cases of epithelial ovarian cancer and 10 paired cases of normal ovarian tissue.Results In the 80 cases of ovarian cancer tissues,the positive expression rate of Twist and VEGF in epithelial ovarian cancer was 85% and 86.25%,respectively,which were remarkably higher than those in normal ovarian tissues (P <0.01).The expressions of Twist and VEGF were closely associated with clinical stages,pathological grades and lymph node metastasis,but not correlated with age or pathological patterns (P >0.05).There was a significant correlation between the expressions of Twist and VEGF in epithelial ovarian cancer (r =0.646,P <0.01).Conclusion The high expressions of Twist and VEGF may play a potential role in the occurrence,development and invasion process of epithelial ovarian cancer.

This study was aimed to explore the mechanism ofZi-Bu Pi-Yin Recipe (ZBPYR) on autophagy and endoplasmic reticulum stress (ERS) to improve spleen-yin deficiency diabetes-associated cognitive decline (DACD). Rats were randomly divided into the control (cont) group, the diabetes (DM) group, the spleen-yin deficiency (pi) group, the spleen-yin deficiency diabetes (piDM) group, and the spleen-yin deficiency diabetes + ZBPYR treatment (ZBPYR) group. The expression of microtubule-associated protein 1A/1B-light chain 3 (LC3Ⅱ), inositol-requiring enzymeα (IRE1α), c-Jun N-terminal kinase (JNK) were observed by western blot. The results showed that the expression of LC3Ⅱ in the DM group, pi group and piDM group decreased compared with the cont group (P < 0.05); and the expression of LC3Ⅱ of the ZBPYR group increased compared with the DM group and piDM group (P < 0.05). Compared with the cont group, the p-IRE1α of the DM group and piDM group, as well as p-JNK1 in the pi group and piDM group were increased (P < 0.05). The p-IRE1α and p-JNK1 of the ZBPYR group were decreased compared with the DM group and piDM group (P < 0.05). It was concluded that ZBPYR improved spleen-yin deficiency DACD by regulating autophagy and ERS.
