Objective To investigate the application validity of the adjusted norm of WAIS-RC in the identification of intellectual disability.Methods128 patients with mental retardation (MR) were chosen for identification of the intellectual disability, measured their full scale IQs (FIQ) according to the original norm, calculated their four-subtest short forms FIQ respectively by Tellegen way according to the original standard norm and the new adjusted norm, then compared and analyzed the outcomes.ResultsThe short forms FIQ according to the original and the new norm had high correlation to full forms FIQ (P<0.01). The average of the short forms FIQ was higher than full forms FIQ according to the original norm (P<0.01), showing no significant difference according to the new norm(P＞0.05). In severe intelligence defected group according to full forms IQ, the grade classification corresponding rate of short forms FIQ according to the new norm was 0.00%, as well as the original norm. That in medium and mild intelligence defected groups was higher than that of original norm(P＜0.01).ConclusionThe test validity of adjusted norm short forms of WAIS-RC is superior to the original norm, but not suitable for severe intelligence defected.

Objective To investigate the effects of exercise training(ET)on the expression of glucogen synthase kinase 3 bate(GSK 3?)in the adipose tissues of insulin resistant(IR)rats on a high fat diet(HFD). Methods Thirty male Wistar rats were randomly divided into a control group(n=10)and a model group(M group,n=20).Insulin resistance was established by feeding a HFD to the M group for 4 w,while rats in the control group were fed a normal diet.The IR rats were then randomly divided into two subgroups:an IR group and an ET group.All rats in the IR and ET groups were fed a HFD,but ET was administrated to the ET group for 6w.The expres- sion of GSK 3?protein in the rats'epididymis adipose tissue was detected using Western blotting,and body weight (BW),the concentrations of serum triglyceride and cholesterol(TG and TC),fasting plasma glucose(FPG)and serum insulin(FINS),as well as insulin sensitivity index(ISI)were regularly detected.Results Compared with the con- trol group,BW and the concentrations of serum TG and TC,FPG and FINS in the model group were significantly in- creased(P＜0.05),while ISI was decreased(P＜0.01).Compared with the control group,there was no difference in GSK 3 protein expression in the ET group,but the expression of GSK 3?protein in the ET group was obviously de- creased in comparison with that in the IR group(P＜0.05).Conclusion ET can ameliorate IR by decreasing GSK 3?protein expression in adipose tissues and enhancing the ingestion of glucose and the synthesis of glycogen.

OBJECTIVE To explore the role of gecko crude peptides (GCPs) in the proliferation, apoptosis, migration and lymphangiogenesis of human hepatocellular carcinoma cells (HepG2) and human lymphaticendothelial cells (HLECs) in vitro. METHODS The 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay was used to evaluate the anti- proliferative effect of GCPs and siRNA-VEGF-C on HepG2 cells, Hoechst 33258 staining and flow cytometry were performed to analyze cycle and apoptosis. The migration and invasion ability of cells were assayed by transwell chamber experiment and wound-healing assay. The protein and mRNA expressions of vascular endo?thelial growth factor-C (VEGF-C) and CXC chemokine receptor-4 (CXCR4) were detected by q-PCR, immunofluorescence, Western blot. The protein expressions of the extracellular signal regulated kinase (ERKI/2), c-Jun N-terminal kinase (JNK), p38-mitogen activated protein kinases (p38 MAPK), serine/threonine kinase (Akt) and phosphatidylinositol- 3- kinase (PI3K) were detected by western blot. The anti-lymphangiogenesis effect of GCPs on the HLECs was analyzed using an in vitro tube-formation assay. The protein and mRNA expressions of vascular endothelial growth factor receptor-3 (VEGFR-3) and stromal cell-derived factor-1 (SDF-1) were detected by q-PCR, Western blot. RESULTS GCPs and siRNA-VEGF-C inhibited HepG2 proliferation, invasion and migration, and the most obvious inhibitory effect was both synergistic effects. Thus, GCPs suppressed HLECs proliferation, migration and tube-like structure formationin a dose- dependent manner, and had inhibitory effect of tumor- induced lymphangiogenesis in vitro. Additionally, we found that GCPs and siRNA- VEGF- C decreased the expressions of MMP-2, MMP-9, VEGF-C, CXCR4, phospho-ERK1/2, phospho-P38, phospho-JNK and PI3K in HepG2 cells. Moreover, GCPs had a dose-dependent depressive effecton the expressions of VEGFR- 3, SDF- 1 in HLECs. CONCLUSION The low expression of VEGF- C mediated by siRNA-VEGF-C and GCPs inhibit tumor proliferation, invasion and migrationby suppressing the MAPK signaling pathway through reduced levels of VEGF-C, and GCPs inhibit tumor lymphangiogenesis by suppressing the CXCR4/SDF-1 signaling pathway through suppressed VEGF-C/VEGFR-3.
