Objective To explore the mechanism of endotoxemic injury in kidneys and protective effect of dexamethasone on renal cells.Methods Fifty-four eighteen-day Wistar rats were divided into control,endotoxemic(LPS)and dexamethasone groups randomly,18 rats in every group.Rats in control group were injected intraperitoneally with the same volume(0.1 mL)of 9 g/L sodium chloride as other two groups.All rats in LPS group were injected with a single bolus of LPS(4 mg/kg).The rats in dexamethasone group received LPS(4 mg/kg)and dexamethasone(5 mg/kg).Then they were sacrificed at 6,24 and 72 hours after injection.The ultrastructure was observed by electron microscope.Results In LPS group,glomerular basement membrane became thick and foot processes had coalescent partly,mitochondrial cristae became dissolved in proximal tubular endothelial cells and microvillus of distal tubular diminished at 6,24 hours after LPS injection.The morphological changes of apoptosis were found in the proximal tubular at 72 hours after LPS injection.These changes were in dexamethasone group.Conclusion Apoptosis participates in LPS injury of kidneys and dexamethasone have protective effect on injuried renal cells.

UNLABELLEDTo investigate the clinical and pathological characteristics, treatment, and The data of 12 patients prognosis of synchronous primary cancer of the endometrium and ovary. Methods with synchronous primary cancer of the endometrium and ovary were retrospectively reviewed . Results Eight patients had the same histological type of endometrioid carcinoma in both uterus and ovary, 4 patients had different histological types in uterus and ovary. Synchronous primary cancer of the endometrium and ovary was difficult to be dignosed preoperatively. All ovarian tumors were small with an average diameter of 7 cm. Infertility was common among these patients(40.7%). Most of them had early stage I lesion (66.7%). endometrioid carcinomas was the main pathologic type (66.7%). All patients were treated surgically followed by chemotherapy with a 3-year survival rate of 66.7% (8/12).

CONCLUSIONSynchronous primary endometrium and ovary cancer is a specific kind of tumor different from either the primary endometrium carcinoma or ovary carcinoma, and usually can be detected in early stage with a good prognosis.

T cell immune receptor with Ig and ITIM domains (TIGIT), a promising new target in cancer immunotherapy, plays a critical role in limiting adaptive and innate immunity against tumors. The extracellular domain of human TIGIT was used to immune BALB/c mice, and a new anti-human TIGIT chimeric antibody (c7D3) was developed. The mice in this study were used in accordance with the international guidelines for the care and use of laboratory animals, and the animal study was approved by the Institutional Animal Ethics Committee of AbMax Biotechnology. The biological activity of c7D3 was studied. The results showed that c7D3 exhibited high affinity for TIGIT and effectively inhibited the interaction between TIGIT and its ligands. Cell-based assays indicated that c7D3 induced strong luciferase signaling in TIGIT/CD155 signaling reporter assay and enhanced cytokine secretion in a T cell stimulation assay. The data showed that c7D3 has high binding affinity and excellent blocking bioactivity, supporting the further advancement for therapeutic application.

Objective: To study the antibacterial activity in vitro of Xiyanping injection combined with cefoxitin, cefuroxime, ceftriaxone, cefmenoxime, amikacin, levofloxacin and meropenem against staphylococcus aureus, escherichia coli, klebsiella pneumoniae, pseudomonas aeruginosa and acinetobacter bauman.Methods: Minimum inhibitory concentration (MIC) of the 7 kinds of antimicrobial agents used individually or combined with Xiyanping injection on germs were determined respectively on 96 plates by using the agar dilution method and the checkerboard method.Fractional inhibitory concentration index (FICI) was calculated to evaluate the antibacterial activity of Xiyanping injection combined with the 7 kinds of antimicrobial agents in vitro.Results: MIC of Xiyanping injection combined with cefoxitin was the same as that of cefoxitin used individually on escherichia coli.MIC of levofloxacin combined with Xiyanping injection showed no difference with that of levofloxacin used individually on klebsiella pneumoniae.Besides, Xiyanping injection could increase the MIC of the other antimicrobial agents on germs.Conclusion: Xiyanping injection combined with antimicrobial agents on staphylococcus aureus, escherichia coli, klebsiella pneumoniae shows antagonistic and irrelevant relationship.

OBJECTIVETo investigate the clinicopathological features of primary gastrointestinal non-Hodgkin's lymphomas (PGI-NHL) and their prognostic values.

METHODSThe clinical and pathological data of 216 patients diagnosed as PGI-NHL from Zhejiang Cancer Hospital were analyzed retrospectively. χ² test, log-liner model analysis, COX proportional hazard regression analysis and Life-table survival analysis were used to analyze the survival status of the patients by SAS 8.2 software, and Log-rank test was performed to couple the overall survival rates with different prognostic factors.

RESULTSTotally, the age of onset was 8 to 89 years with the median age of 56.5 years. Male versus female was 1.27∶1(121∶95). The most frequently involved location was stomach (147 cases, 68.1%), followed by ileocecus (25 cases, 11.6%), large intestine (20 cases, 9.3%), small intestine (17 cases, 7.9%) and multiple GI involvement (5 cases, 2.3%). 182 cases were classified as B cell lymphomas, 22 cases as T cell lymphomas, and 12 cases not classified exactly due to insufficient data. The 3-year and 5-year survival rates of the patients were 69.4% and 53.3%, respectively. Univariate analysis revealed that age＞60 years, ECOG≥2, high LDH level, stage Ⅲ-Ⅳ, IPI≥2, T cell type and intestinal involvement were predictors for poor prognosis. IPI≥2, T cell type and intestinal involvement were independent adverse predictors for prognosis by multiple COX proportional hazard regression analysis. Among different treatment groups, cases received chemotherapy combined with local radiotherapy gained the best survival status.

CONCLUSIONB-cell lymphoma was the main pathological type in PGI-NHL; IPI≥2, T-cell type and intestinal involvement are independent adverse predictors for prognosis; chemotherapy combined with local radiotherapy might be the choice of approach for advanced stage and aggressive PGI-HNL.

Purpose To study the clinical features, immunophenotypes and prognostic factors of primary breast diffuse large B-celllymphoma (PBDLBCL). Methods The clinical pathological data of 49 cases of PBDLBCL during January 2006 to December 2016 were retrospectively analysed, and the basic clinical and pathologic data, pathologic types and the immunohistochemical slides by EnVision method for staining were summarized. Results 47 cases were women and 2 cases were men. The age ranged from 24 to 79 year old with the median age of 48 year old. On microscopic observation, tumor cells were large to medium-sized which characterized as diffuse infiltration between the lobules of mammary gland, around the duct, interstitial and fat tissue, some were single file cord pattern. The immunophenotype showed 37 cases were of non-GCB, 12 cases were GCB type. Ki-67 index were greater than 40％. According to Ann Arbor staging, 16 cases were stage I EA, 28 cases were stage Ⅱ EA, 5 cases were stage Ⅳ E. IPI score: 30 cases with 0 ～1 score, 10 cases with 2 score, 9 cases with 3 score. Patients were followed up from 5 to 146 months, The 3-year overall survival (OS) rate was 51.2％ and 5-year OS rate was 36.7％, Single factor analysis showed that there were statistically significant difference in clinical stage, levels of LDH, IPI score, BCL-2 protein expression, and BCL-6 protein expression in 3 and 5 years of OS rate. The multiple factor analysis of Cox regression showed that the increase of IPI risk classification was the independent adverse prognostic factor of primary breast diffuse large B-cell lymphoma. Conclusion The diagnosis of PBDLBCL is confirmed by pathological biopsy and immunohistochemical markers. The immunophenotype was mainly non-GCB type. Comprehensive treatment including surgery, chemotherapy and radiotherapy is appropriate. The prognosis should be comprehensively evaluated by multiple factors. IPI increase risk classification is the independent adverse prognostic factor.

BACKGROUNDWe investigated the pathogenesis of atherosclerosis in diabetes, and detected the expression of scavenger receptor CD36 in monocytes in patients with type 2 diabetes.

METHODSAccording to the criteria by WHO, diabetic patients were classified into two groups: well controlled diabetic patients (WCP) and poorly controlled diabetic patients (PCP). The expression of CD36 protein and mRNA were evaluated by flow cytometry and reversal transcription polymerase chain reaction (RT-PCR). Plasma levels of accumulation of oxidized LDL (oxLDL) were directly measured by sandwich enzyme-linked immunosorbent assay (ELISA) method.

RESULTSFlow cytometry and RT-PCR showed that the mean fluorescence intensity (MFI) of CD36 in monocyte and CD36 mRNA were significantly higher in the PCP and WCP in comparison with healthy controls (P<0.01). CD36 MFI and mRNA in the PCP were increased by 78% and 36% compared to the WCP. In both groups, CD36 MFI and mRNA were significantly higher in patients with diabetic atherosclerosis in comparison with those without diabetic atherosclerosis (P<0.05). No significant difference was found in CD14 expression between the groups (P>0.05). The concentrations of plasma oxLDL were higher in the PCP group compared to WCP and control group (P<0.05), whereas oxLDL average values did not differ significantly between WCP and control groups (P>0.05). In the WCP and PCP groups, oxLDL levels were higher in patients with diabetic atherosclerosis than those without diabetic atherosclerosis (P<0.05).

CONCLUSIONSThe increased expression of scavenger receptor CD36 may be one of the mechanism of accelerated atherosclerosis in diabetic. The poorly controlled diabetes patients are at higher risk for the vascular complications than the well controlled diabetic patients.
