Objective To investigate the effects of rapamycin on renal tissue and function of rats with protein overload nephropathy and to explore the protective mechanism of losartan. Methods Experimental rat models with protein overload nephropathy, induced by intraperiotoneal injection of BSA (2. 0 g/d)into female Wistar rats, were divided into three groups: control group, rapamycin group(injected intraperitoneally with rapamycin) and losartan group(injected intraperitoneally with rapamycin and given orally with losartan). At different time points, the quantity of 24-hour urine protein and renal function were measured, and the morphologic changes of renal tissues were evaluated by HE staining and electron microscope. Results Both at day 7 and day 14, rats received BSA developed intense proteinuria. At day 7, compared with control group, 24-hour proteinuria increased markedly in rapamyein group (P<0.05). Nevertheless,proteinufia was notably alleviated in losartan group (P<0.05). At day 14, 24-hour-urine protein of rapamycin group was also significantly higher than that of the losartan group (P<0.05), but therewas no significant difference between control group and losartan group (P>0.05). Proteinuria and intratubular albumin cast formation were alleviated notably in losartan group. The fusion of focal podocytes in rapamycin group was obvious in comparison with control group. Conclusions Rapamycin can agrravate proteinuria in rats with protein overload nephropathy through changing the barrier of glomerular filtration by damaging podocytes. Furthermore, losartan can alleviate severe proteinuria induced by rapamycin.

Objective To estimate the application for the rapid identification of common clinical bacteria by MALDI-TOF MS. MethodsFour hundred and twenty-six bacteria, including Salmonella spp strains collected from Zhejiang center for disease control and prevention were collected from blood, sputum,secretion and urine in 2nd Affiliated Hospital of Zhejiang University during December 2008 to August 2009. The isolates included 76 gram positive coccus and 350 gram negative bacilli. Species identification was performed with the Vitek system, and serotypes of Salmonella and Shigella were determined by serum agglutination test. 16s rDNA gene of 91 bacteria were amplified by PCR. The RCP products were sequenced. Then the results were compared with the reported sequences from GenBank. All strains were identified by MALDI-TOF MS. Results of three identification methods were compared with each other. Results Among 426 tested isolates, identification results from Vitek system and MALDI-TOF MS for gram positive coccus and 323 out of 350 gram negative bacilli (exception for Salmonella and Shigella spp.),were identical. For 23 Salmonella and Shigella spp. , only 2 Salmonella enterica subsp, enterica serovar Typhimurium were identified the same results by the three methods. Besides, results from Vitek system and serum agglutination test for 1 Salmonella enterica subsp, enterica serovar Typhi, 3 Salmonella enterica subsp.enterica serovar Paratyphi A, 1 Salmonella enterica subsp, enterica serovar Paratyphi B, 1 Salmonella enterica subsp, enterica serovar Enteritidis, and 1 Salmonella enterica subsp, enterica serovar Bovis-morbificans were consistent with that from 16S rDNA gene sequence. Four isolates which were confirmed as S. flexneri by Vitek system and serum agglutination test were identified as Escherichia coli by both 16S rDNA gene sequence and MALDI-TOF MS. ConclusionMALDI-TOF MS could be used for rapid and accurate identification of common clinical bacteria with good repeatabihty, excepting for the Salmonella and Shigella spp.

AIM: To investigate the apoptosis in primary gastric cancer cells induced by resveratrol, and the relation between this apoptosis and expression of bcl- 2 and bax. METHODS: In in vitro experiments, MTT assay was used to determine the cell gowth inhibitory rate. Transmission electron microscopy and TUNEL staining were used to quantitatively and qualitively detect the apoptosis of primary gastric cancer cells before and after the resveratrol treatment. Immunohistochemical staining and RT - PCR was used to detect the expression of apoptosis - regulated gene bcl - 2 and bax. RESULTS: Resveratrol inhibited the growth of primary gastric cancer cells in a dose - and time - dependent manner. Resveratrol induced primary gastric cancer cells to undergo apoptosis with typically apoptotic characteristics. TUNEL assay showed that after the treatment of primary gastric cancer cells with resveratrol for 24, 48, 72, 96 hours, the apoptotic indexs were 4.93% ± 0.19%, 16.74% ± 0.43%, 27.88% ±0.36%, 36.84% ± 1.07 % respectively. Immunohistochemical staining showed that after the treatment of primary gastric cancer cells with resveratrol for 24, 48, 72, 96 hours, the positive rates of Bcl - 2 proteins were 20.68% ± 0.49%, 10.84% ±0.33%, 6.80% ± 0.34%, 3.91% ± 0.15% and the positive rates of Bax proteins were 19.79% ± 0.98%, 30.74% ±0.85%, 40.14% ± 1.17%, 60.08% ± 1.64%. After exposed to resveratrol for 24 h, 48 h, 72 h and 96 h, the density of bcl- 2 mRNA decreased progressively with elongation of time and the density of bax mRNA increased progressively with elongation of time by RT- PCR. CONCLUSION: Resveratrol is able to induce the apoptosis in primary gastric cancer. This apoptosis may be mediated by down- regulation of Bcl- 2 and up- regulation of Bax.

Objective:Based on the detection of CD4+IL17+Th17 and CD4+CD25+Foxp3+Treg cells in the peripheral blood of patients with human papilloma virus (HPV), the study analyzes the ratio of Th17 to Treg and compares the different expression of cytokine IL-17, IL-10, TGF-β, and IL-23 in the serum. Methods:From September 2014 to June 2016, 119 cases of untreated patients with cervical HPV in-fection were collected at the First Affiliated Hospital of Xinjiang Medical University, which include 46 cases of cervical cancer (CC), 43 cases with cervical intraepithelial neoplasia (CIN)Ⅱ-Ⅲ, and 30 with chronic cervicitis (CCS). The detection of HPV types classified 80 patients as high-risk and 39 as low-risk. Flow cytometry examined Treg and Th17 cells, and enzyme-linked immune sorbent assay was used to test related cytokines. Results:In the infection of high-risk cervical HPV, the rate of the CC group was 87%(40/46), which was higher than that of the CINⅡ-Ⅲgroup and the CCS group, which were 77%(33/43) and 23%(7/30), respectively. For the expression of Th17 and Treg cells in the peripheral blood and the related cytokine IL-17, IL-23, TGF-β, and IL-10 in the serum, the levels of CC group were also significantly higher than that of the other two groups, and the ratio of Th17 to Treg increased considerably with the se-verity of cervical lesions. The expression of Th17 and Treg cells in the peripheral blood of patients with high-risk cervical HPV were higher than that of patients with low-risk cervical HPV (P<0.05), which was the same for the expression of the related cytokine IL-17, IL-23, TGF-β, and IL-10 in the serum. The ratio of the Th17 to Treg of patients with high-risk cervical HPV increased remarkably (P<0.05). Conclusion:The expression of Treg and Th17 cells in high-risk patients exhibits an increasing trend, and the ratio of increased Th17 to Treg may directly participate in the process of HPV infection and immune evasion, which plays an important role in the occurrence and development of cervical cancer.
