[ ABSTRACT] AIM:To investigate the effect of Ginkgo biloba extract ( GBE) on diabetic retinopathy ( DR) and its possible mechanism in rats .METHODS:Goto-Kakizaki ( GK) rats were used as a DR model, and were treated with different doses of GBE.Normal Wistar rats were used as the control.Blood glucose and retina barrier injury were analyzed, respectively.Ganglion cell apoptosis was detected by TUNEL staining.Moreover, the protein expression of nuclear factor E2-related factor 2( Nrf2) , ERK, Bcl-2 and P53, and ERK phosphorylation were examined by Western blot.RESULTS:GBE reduced blood glucose in the DR rats, attenuated retina barrier injury, and decreased the apoptosis of ganglion cells. Furthermore, the expression of Nrf2 and Bcl-2, and phosphorylation of ERK were increased after GBE treatment, whereas P53 expression was decreased.CONCLUSION:GBE protects ganglion cells against apoptosis in DR rats, which may be through activation of Nrf2/ERK pathway and regulating Bcl-2 and P53 expression.

Objectives The aim of the study was to detect the frequency of B regulatory cells (Breg)and the correlation between Breg and T regulatory cells (Treg) in pancreatic cancer patients,and to investigate its role in pathogenesis of pancreatic cancer.Methods 50 pancreatic cancer patients and 21 healthy controls were enrolled.CD19+CD24hiCD38hi Breg and CD4+CD25high Treg was also determined via flow cytometry.The correlation between Breg and Treg was analyzed by Spearman correlation test.Results Upregulation of CD19+CD24hiCD381hi Breg was associated with pancreatic cancer progression.Furthermore,this B cell subset was positively correlated with the frequency of CD4 + CD25high Treg cells.Conclusions Together,CD19 + CD24hiCD38hi Breg cells are significantly elevated in pancreatic cancer patients,indicating this B cell subset might play an vital role in clinical progression of pancreatic cancer.The significant positive correlation between Breg and Treg may suggest CD 1TCD24hiCD38hi Breg are affecting tumor progression through Treg cells.

Objective:To observe the changes of glyeemia, urine protein, serum creatinine, blood urea nitrogen and glycosylated hemoglobin in diabetic nephropathy rats and treating effects of Xiaokekang. Methods: Streptozotocin (STZ) was abdominally administered and was feeded by high lipid diet to establish diabetic nephropathy model in rats. Animals were divided into three groups: model group, Xiaokekang treatment group and normal group. Changes in glycemia, serum lipids, serum creatinine, blood urea nitrogen were measured at the 8th, 12th and 16th week after STZ injection. Glycosylated hemoglobin was measured at the 16th weeks after STZ injection. Results: Glycemia, serum lipids, serum creatinine were higher at the 8th, 12th and 16th week compared with normal group. Serum creatinine was higher at the 12th and 16th week, and glycosylated hemoglobin was also highter than that of the normal group. Xiaokekang reduced these changes. Conclusion: Xiaokekang can reduce glycemia, serum lipids and protect renal function.

Objective To investigate and validate the expression profiles of Ppp3cb and Ppm1g through differential proteomic analysis of hippocampal tissue in NHE1 gene knockout mice with proteomic analysis.Method ① Six 2-week-old NHE1 knockout mice were selected as the model group,and 6 wild-type mice of the same age served as the control group,and their genotypes were detected by agar-gel electrophoresis.Open field test and forced swimming test were used to evaluate the behaviors of mice in the model group and control group,and epileptic seizure was graded according to Racine scoring.② Tandem mass spectrometry was employed to screen the differential proteins in the hippocampus tissues from the model group and the control group.Then the obtained differential proteins were annotated and enriched in the Gene Ontology(GO)database.Search tool for the retrieval of interesting genes(STRING)database was used to analyze protein-protein interaction(PPI)among different proteins.③ The transcriptional and translational levels of Ppp3cb and Ppm1g were detected by qPCR and Western blotting,respectively,and their expression levels in the tissues were observed with immunohistochemistry.Results ① NHE1 was not expressed in the model group.The mice of the model group had shorter total movement distance(P=0.007 3)and less crossing cells(P＜0.000 1)in open field test,and longer period of immobility in forced swimming test(P＜0.000 1)when compared with those from the control group.② When fold change ≥1.2 times and P＜0.05 were set as the significant threshold for differential expression,845 differentially expressed protein sites were detected in the hippocampus,among which 9 proteins(including Ppm1g)were up-regulated and 7 ones(including Ppp3cb)were down-regulated.Gene Ontology(GO)functional analysis showed that after NHE1 knockout,the most significant differences were observed in the concentration of molecular function(MF)related to protein serine/threonine phosphatase activity,concentration of cellular component(CC)related to the plasma membrane,and concentration of biological process(BP)related to negative regulation of biological processes and immune system processes.STRING analysis indicated that the differential proteins Ppp3cb and Slc9a1 directly acted,Ppm1g indirectly acted through Ppp3cb and Slc9a1,and Ppp3cb and Ppm1g interacted.③The transcriptional and translational levels of Ppp3cb were decreased,and its expression level was reduced in the tissues,while those of Ppm1g were increased,and its expression was elevated in the tissues(P＜0.05).Conclusion In the hippocampus of NHE1 gene knockout mice,the expression of differential protein Ppp3cb is down-regulated and that of Ppm1g is up-regulated,which provide a basis for further study on their involvement in the pathogenesis of epilepsy.

OBJECTIVETo elucidate the epidemic condition and molecular subtyping of ciprofloxacin and cefotaxime co-resistant Salmonella Indiana (S. Indiana) isolated from retail chicken carcasses in six provinces of China.

METHODSA total of 2 647 Salmonella strains isolated from retail chicken carcasses collected from six provinces of China were subjected to antimicrobial susceptibility testing. All Salmonella isolates co-resistant to ciprofloxacin and cefotaxime were further characterized by serotyping, extended-spectrum beta-lactamases (ESBLs) producing strains screening and pulsed field gel electrophoresis (PFGE) typing.

RESULTSAmong 2 629 Salmonella isolates tested, 227 (8.52%) isolates were co-resistant to ciprofloxacin and ceftazidime/cefotaxime (Beijing: 11.67% (99/874), Jilin: 8.20% (60/726), Guangdong: 1.39% (7/502), Jiangsu: 15.61% (42/260), Shaanxi: 8.56% (16/186), Inner Mongolia: 0 (0/81)), and 224 of them were identified as S. Indiana. 213 (95.10%) isolates of S. Indiana were ESBLs producing strains. All ciprofloxacin and cefotaxime co-resistant S. Indiana isolates developed a multi-drug resistant profile and 17.86% (40/224) of them were resistant to all antibiotics tested except carbapenems, and 50.89% (114/224) of them resistant to 9 antibiotics, additionally, 25.45% (57/224) of them showed multi-drug resistance to 8 antibiotics. All ciprofloxacin and cefotaxime co-resistant S. Indiana isolates were divided into 32 PFGE clusters and 150 PFGE patterns. Strains of S. Indiana from same or different sampling site and time seemed to either share the same PFGE patterns or be differential to each other in different regions.

CONCLUSIONThe results indicated that chicken carcasses collected from parts of China were heavily contaminated by ciprofloxacin and cefotaxime co-resistant S. Indiana and could serve as an important reservoir of ciprofloxacin and cefotaxime co-resistant Salmonella. Molecular subtyping results indicated that cross contamination or common pollution source might be in these strains.
