Objective: To investigate peroxisome proliferator activated receptor ? (PPAR ?) expressions in patients with actively proliferating glomerulonephritis such as type Ⅳ lupus nephritis (LN) and cellular crescentic glomerulonephritis (RPGN). Methods: All patients were divided into 4 groups as follows: RPGN (17 cases); LN type Ⅳ (15 cases); mild mesangial proliferative IgA nephropathy (IgAN, 7 cases) and minimal change disease (MCD, 10 cases). Clinical parameters, immunohisto chemistry stain and in situ hybridization of renal biopsy specimens were performed. Results: Clinically, proteinuria and hematouria were increased and Ccr were decreased in LN and RPGN patients, and increased ESR and decreased complement C3 were found in group LN. Active index of renal specimens were significantly higher in LN and RPGN groups than in IgAN and MCD groups. Renal specimens of MCD patients showed no positive PPAR ? staining in all sections; little immunoreactivity was detected in sections of glomerular, tubular and interstitial cells from IgAN patients. Glomerular positive staining of PPAR ? in renal sections in LN and RPGN patients[(3.3?1.8) and (2.8?1.2) cells per section of glomerulus, respectively] were significantly increased compared with that in IgAN patients [(0.7?0.5) cells per section of glomerulus]. Similarly, tubular positive staining of PPAR ? in LN and RPGN patients (27.38? 12.46, 23.36?10.55) were also elevated compared with that in IgAN and MCD patients(6.51?3.49, 1.72?0.31). The relevance assay results showed positive relationship between active index and glomerular or tubular PPAR ? immunohisto chemistry staining cell numbers (0.478, P

Objective:To determine the related substances in benzalkonium chloride used as a pharmaceutical adjuvant, and com-pare the quality at home and abroad. Methods:An HPLC method was used with an ODS-HYPERSIL C18 column(250 mm × 4. 6 mm, 5 μm). The detection wavelength was 210 nm and 257 nm. The flow rate was 1. 0 ml· min-1 and the column temperature was 30℃. The injection volume was 20 ml. The mobile phase was A ( dissolving 1. 09 g sodium1-hexanesulfonate and 6. 9 g sodium dihydrogen phosphate in water, adjusting pH to 3. 5 with phosphoric acid and diluting to 1 000. 0 ml) and B ( methanol) with gradient elution. Results:The content of benzaldehyde in the samples at home and abroad was low. The content of benzyl alcohol in the samples from a-broad was qualified, which was significantly higher than that in the domestic samples. The content of benzyl chloride in the domestic samples was higher than that in the samples from abroad. Conclusion:The method is simple and fast, which is suitable for comparing the related substances of domastic and imported samples. At the same time, the study provides basis for enterprises to choose benzalko-nium chloride rationally.

Commensal microorganisms that colonize barrier surfaces of all multicellular organisms exist in harmony with their hosts and have an important effect on both immune and non-immune functions of their hosts. Numerous researches have shown that gastrointestinal microbiota being one of the most important commensal microorganisms plays a critical role in the occurrence, development and treatment of cancer. As-signing causal roles in cancer to specific microbes and microbiotas, unraveling host-microbiota interactions with environmental factors in carcinogenesis, and applying such knowledge to cancer diagnosis and treatment are areas of intensive interest. This review considers how microbes and the microbiota may amplify or miti-gate carcinogenesis, responsiveness to cancer therapeutics, and cancer-associated complications.

Objective:To compare the quality differences in benzalkonium chloride samples from domestic and abroad to provide references for the quality standard revision for benzalkonium chloride in Chinese pharmacopoeia. Methods: The ratio of alkyl compo-nents was determined according to the method described in USP 38, and the total content of benzalkonium chloride was determined ac-cording to the method recorded in Chinese Pharmacopoeia (2015 edition) and USP 38, respectively. Results:According to the results of composition ratio of alkyl, the fraction defective of domestic samples and imported samples was 100% and 50%, respectively. The content difference between the values calculated by the methods in the two pharmacopoeias showed that the total content of domestic samples changed from 3. 86% to 4. 15%, and that of imported samples changed from 1. 15% to 3. 90%. Conclusion:There are sig-nificant differences in the quality of benzalkonium chloride between domestic samples and imported samples. It is recommended that the ratio of alkyl components should be supplemented in our pharmacopoeia referring to the method in USP 38 and the total content calcula-tion formula for benzalkonium chloride should be revised to improve the quality standard for benzalkonium chloride.

ObjectiveTo investigate the effect of percutaneous coronary intervention (PCI) treatment on quality of life and prediction in patients with chronic total occlusion.Methods87 patients with chronic total occlusion who had underwent PCI to revascularization were studied. 57 cases had successfully revascularized and implanted stenting. 30 cases failed to revascularize. Their activity of living, quality of life and long prediction were observed.ResultsAfter 6～60 months follow-up, the quality of life in patients with successful revascularization was much better than that in patients who failed to revascularize. Mortality between these two groups showed no significant difference. ConclusionSuccesful revascularization by PCI on chronic total occlusion can improve quality of life.

Objective To evaluate shell vials of MHV,a combination of Madin-Darby canine kidney cells (MDCK),human epidermoid cancer cells (Hep-2) and African green monkey kidney cells (Vero),and conventional cell culture in detecting influenza viruses and enterovirus from fresh clinical specimens.Methods Specimens from patients with influenza-like illness and children with hand-foot-mouth disease were inoculated with both shell vials of MHV and MDCK/Vero.Then cytopathological effect (CPE) was examined daily.Influenza viruses and enteroviruses were detected by multiple reverse transcriptase-polymerase chain reaction (mRT-PCR).Results CPE of MDCK/Vero cells were stronger than the shell vials of MHV.The isolation rate of influenza virus by MHV was 24.6％ (34/138) and that by MDCK was 28.3％ (39/138),which was not significantly different (x2 =1.92,P＞0.05).That of enterovirus by MHV was 28.1％ (9/32) and that by Vero was 37.5％ (12/32),which was not significantly different (x2 =3.00.P＞0.05).Conclusions CPE in MDCK/Vero cells are easier to be observed than the shell vials of MHV.However,the shell vials of MHV are appropriate in public health emergencies,which can be used for isolation of influenza viruses and enterovirus in patients with respiratory symptoms.
