A total of 1342 individuals underwent physical examinations according to the criteria of metabolic syndrome of International Diabetes Federation (IDF) in 2005.And 314 patients with metabolic disorders were screened for diabetes by standard meal and methods oral glucose tolerance test (OGTT).Newly diagnosed diabetics was 12 (4.1％ ) vs.17 (5.8％) respectively.No significant difference existed between two methods (P =0.332).Kendall's (τ)b =0.313,Kendall's (τ)c =0.208 and Gamma coefficient =0.580 (P =0.000).The mixed meal method was correlated with OGTT,Kappa =0.258 (P =0.000) and two methods were consistent.Diabetic screening should be stressed in the subjects with metabolic abnormalities.And the detecting efficiency of postprandial plasma glucose is similar to OGTT.

Objective To find out a quick,simple and convenient method of determining the viability of Oncomelania hupen-sis. Methods O. hupensis snails were stained for 30 minutes by 0.05%water soluble dye neutral red,0.5%methylene blue,red ink,methylene blue-eosin-borax(MEB)and 0.4%trypan blue,respectively. The soft tissue samples of the snails were observed by a stereoscopic microscope after crushing their shells. Results The vital snails were stained and the dead were unstained in the neutral red. The vital and dead snails were unstained in methylene blue. However,the vital and dead snails were stained in red ink. The partial vital and dead snails were stained in MEB. The vital snails were stained and the partial dead were stained in trypan blue. Conclusion The use of 0.05%water soluble dye neutral red is simple,rapid and accurate in determination of the viability of O. hupensis.

Totally 1136 individuals aged over 40 underwent health check up in March to May 2009. Fasting blood glucose, 2-h post-challenge blood glucose, glycated hemoglobin A1c ( HbA1c), total cholesterol, triglyceride, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol and serum uric acid were measured. The diagnosis of metabolic syndrome was based on the International Diabetes Federation Criteria. The results shows that total body fat, region body fat indices, blood pressure, blood glucose and serum uric acid levels increased with the age ( P < 0.01) . The prevalence rate of metabolic syndrome in this group of individuals were 15. 1% (171/1136) , and increased with age (P<0.01). The most common combination of metabolic syndrome was central obesity-hypertension-dyslipidemia (40. 9% , 70/171). Unconditional logistic regression revealed that waist-hip-ratio, body mass index and uric acid were the risk factors for metabolic syndrome.

BackgroundOptic nerve injury lead to apoptosis of retinal ganglion cells ( RGCs ), and its mechanism of apoptosis is endoplasmic reticulum stress (ERS). So, decreasing of ERS may protect the injury of RGCs. ObjectiveThe present study was to investigate the mechanisms of endoplasmic reticulum stress(ERS) and the protective effects of human umbilical cord blood stem cells on partial optic nerve crush injury. MethodsThe optical nerves were crushed with a 40 g clip by holding for 60 seconds to establish the partial optical nerve injury model in the left eyes of 102 SPF SD rats,and 10 μl of mRNA and 10 μl of nerve growth factor were injected into the vitreous immediately after the establishment of the model. The morphological changes of retinal ganglion cells(RGCs) were examined under the light microscope after 3,7,14,21 and 28 days and the RGCs number was calculated. The apoptosis rates of RGCs were detected by the TUNEL technique after 3, 12,24,45,72 hours and 1 week. The expression levels of GRP78 mRNA and CHOP mRNA were detected by reverse transcription polymerase chain reation (RT-PCR). This procedure followed the Regulations for the Administration of Affair Concerning Experimental Animals by Hunan Provincial Science and Technology Committee.Results The number of RGCs was significantly decreased with the prolongation of time of optical nerve injury in the model injury group,whereas the number of RGCs in the human cord blood cells group was reduced at a slower rate( Ftime =20. 100,P =0. 007 ). At various time points after the injection of human cord blood cells, the survival of RGCs was evidently increased in comparison with the model group(P＜0. 01 ). The apoptosis rate of RGCs was considerably elevated with injury time prolongation both in the model group and human cord blood cells group,but no apoptosis was seen from 3-24 hours after operation,and only a small amount of apoptotic cells were found in the human cord blood cells group from 48 hours through 1 week than in the model group(P＜0. 01 ). In the human cord blood cells group,GRP78 mRNA level was significantly higher and the CHOP mRNA level was significantly lower than those in the injury group at identical time points(P＜0. 01 ). ConclusionsIn the rat optic nerve partial crush model,ERS induces the apoptosis of RGCs. Human umbilical cord blood stem cells can protect RGCs from ERS injury by inhibiting apoptosis.

Objective To investigate the role of microRNA-129-5p (miR-129-5p) in the regulation of epithelial-mesenchymal transition (EMT) of human peritoneal mesothelial cells (HPMCs) isolated from peritoneal dialysate effluents and TGF-β1 induced HPMCs line.Methods The isolated cells were cultured from peritoneal dialysate effluents overnight of 10 patients just started PD and 12 patients with PD over 6 months.Taqman PCR assay was used to determine the expression of miR-129-5p in the HPMCs.Moreover,the expression of miR-129-5p in HPMCs induced by 5 μg/L TGF-β1 for 0-72 h was also detected by Taqman PCR.HPMCs were pre-transfected with miR-129-5p precursor (pre-mir-129-5p) to overexpress miR-129-5p,then incubated with TGF-β1 for 48 h,and the expression of EMT associated gene and protein was detected by real-time PCR,Western blotting and immunofluorescence,respectively.Furthermore,the effect of TGF-β1 on the expression of Smad interacting protein-1 (SIP1) and the regulation of pre-miR-129-5p on the SIP1 expression also were investigated.Results MiR-129-5p expression significantly down-regulated in the HPMCs isolated from PD patients over 6 months than from PD start patients(P ＜ 0.01).Similarly,TGF-β1 remarkably decreased miR-129-5p in HPMCs lines on time-dependent manner (P ＜ 0.01).Pre-mir-129-5p dramatically restored the expression of epithelial marker E-cadherin,while inhibited the expression of Vimentin,a mesenchymal marker,in HPMCs induced by TGF-β1 (all P ＜ 0.01).In addition,TGF-β1 increased SIP1 expression in HPMCs time dependently,while the high level of SIP1 protein was obviously repressed after transfected of pre-miR-129-5p (P ＜ 0.01),but there was no obvious change of its mRNA expression.Conclusion MiR-129-5p modulates EMT formation of HPMCs in PD process,possibly by posttranscriptional inhibition of SIP1.Targeting miR-129-5p/SIP1 may provide a new approach for the prevention and treatment of peritoneal fibrosis during PD.
