AIM:Given the uncertain impact of osmotic pressure on embryoid body(EB)differentiation,this study aimed to investigate the effects of increased osmotic pressure on EB differentiation and explore the potential relation-ship between this process and cadherin.METHODS:Polhethylene glycol 300(PEG 300)was used to increase the os-motic pressure of the culture medium used for cultivating EBs under both high osmotic pressure and standard culture condi-tions.The experimental design included a control group,an experimental group(hypertonic group),groups treated with varying concentrations of PEG 300,and an experimental group treated with an inhibitor.Western blot,RT-qPCR,AM/PI staining,CCK-8,and immunocytochemical staining was used to analyze the cell viability and the expression of CDH1 and CDH2 markers of the three germ layers,and pluripotency markers within the EBs.RESULTS:Hypertonicity did not af-fect cell viability.Significant differences were observed in the expression of the cadherin proteins CDH1 and CDH2 in EBs between the experimental and control groups;however,no cleartrend towards an EMT shift was observed.Specifically,CDH2 expression was significantly down-regulated in experimental group,showing a clear correlation with variations in os-motic pressure.Moreover,compared with control group,pluripotency markers in the EBs from experimental group exhibited significantly higher expression levels from the 2nd day to the 5th day.A substantial increase in the expression of mesoder-mal markers was also observed;however,a downward trend was observed for ectodermal markers in experimental group.Intervention using SB431542,which up-regulates CDH2 expression by affecting TGF-β signaling,reversed the expression trend of mesodermal and ectodermal markers in experimental group.CONCLUSION:Elevated osmotic pressure appears to enhance the mesodermal differentiation efficiency in EBs,possibly correlating with CDH1 and CDH2 changes induced by osmotic pressure.Therefore,this study emphasizes the significant role of osmotic pressure in stem cell applications.

Objective To determine the proper storage environment by comparing the activity of adipose-derived stem cell (ADSC) at 10％ PRP,10％ HS and 0.9％ NaCl.Methods ADSC was isolated and cultured.Then the ADSC was stored in 10％ PRP,10％ HS,and 0.9％ Nacl at room temperature (RT,about 26 ℃C) for 2 hours.After that the proliferation ability,survival rate and differentiation ability of the cells were detected.Finally storage media of ADSC was determined.Results Compared with 0.9％ NaCl,ADSC showed a better proliferation and higher differentiation ability at 10％ PRP and 10％ HS;besides,the survival rates of two groups were higher than the group of 0.9％Nacl.Among these groups,the survive rate of 10％ HS and 10％ PRP were 78.08％ and 75.68％ respectively,while it was 62.34％ in 0.9％ NaCl group.Conclusions 10％ HS is more suitable for short-term preservation of ADSC.

Objective To evaluate the efficacy of intratympanic steroid therapy compared with systemic ster‐oid therapy on the treatment of idiopathic sudden sensorineural hearing loss (ISSNHL) patients with damaged glu‐cose tolerance .Methods Fifty first -diagnosed unilateral ISSNHL patients with damaged glucose tolerance were randomized devided equally to the intervention group (intratympanic steroid therapy) or the control group (systemic steroid therapy) ,all patients received conventional drug therapy simultaneously .Pure-tone hearing threshold tests were performed in all patients every 3 days after the first time ,and repeated measures anova was used to assess effects of hearing recovery accompanied with time .Results The mean hearing threshold in the control group de‐creased from 85 .4 ± 5 .6 dB to 48 .2 ± 4 .9 dB ,while in the intervention group it decreased from 84 .8 ± 5 .6 dB to 31 .7 ± 4 .6 dB .Total effective rate in the intervention group (84 .00% ,21/95) was higher than that in the control group (68 .00% ,17/25)(P<0 .05) .Conclusion The intratympanic steroid therapy is more effective than systemic steroid therapy in the treatment of ISSNHL patients with damaged glucose tolerance .

Conclusion PCT,CRP,WBC are of diaGnostic siGnificance for early diaGnosis of neonatal infection,and PCT has hiGh sensitivity and specificity of diaGnosis of neonatal infectious diseases.

Salmonella enterica serovar Choleraesuis strain C500 is a live, attenuated vaccine that has been used in China for over 40 years to prevent piglet paratyphoid. The objective of this study was to evaluate the potential of attenuated Salmonella enterica serovar Choleraesuis C500 strain with a delta asd mutant as an effective live vaccine vector by the Asd+ balanced-lethal host-vector system. Here, we compared the characteristics of S. enterica serovar Choleraesuis delta asdC500 strain with the parent C500 strain, including phenotype, growth rate, virulence, safety, and expression for heterologous antigen. The mean generation times of delta asdC500 mutant, the vector control delta asdC500 (pYA3493), and the parent avirulent C500 vaccine strain in Luria broth were 30.7, 28.1, and 27.9 min, respectively. The fermentation patterns of theses three strains on different carbohydrates, and the levels of production of H2S, were similar. The O and H antigens of delta asdC500 mutant, delta asdC500 (pYA3493) and delta asdC500 (pYA-F1P2) were 6,7:C:1,5, identical to the parent strain C500. By the method of Reed and Muench, groups of mice were challenged by the intraperitoneal route with different amounts of delta asdC500 (pYA3493) or the parent C500 strain, and the virulence of delta asdC500 (pYA3493) with LD50 of 1.1 x 10(7) CFU was a little lower than C500 with LD50 of 4.4 x 10(6) CFU. All piglets inoculated with delta asdC500 (pYA3493) or C500 survived, and no signs of disease were observed during the entire experimental period. No major differences were found in these two groups. In addition, the recombinant pYA-F1P2 plasmid was very stable in the recombinant delta asdC500 (pYA-F1P2) strain, which expressed secretorily a large amount of the recombinant filamentous hemagglutinin type I domain and pertactin region 2 domain antigen (rF1P2) of Bordetella bronchiseptica. In this study, we have shown that the delta asdC500 mutant had a series of biological characteristics similar to the parent vaccine strain C500. Furthermore, the strain could express secretorily a large amount of heterologous antigen. It is likely that this Salmonella expression and delivery system could be easily adapted to develop multivalent recombinant Salmonella vaccines against infectious agents using the Asd+ balanced-lethal host-vector system.
