Objective:To observe the effects of Salvia Miltiorrhiza Bunge on cell proliferation and differentiation of osteoblasts in rats cultured in vitro.Methods:Osteoblasts from cranium of newborn SD rats were cultured by collagenase method.MTT was used to determine the proliferation of cultured osteoblasts affected by different concentrations of Salvia Miltiorrhiza Bunge at different time points(24,48,72 hrs after medication).Differentiating effect of different concentrations of Salvia Miltiorrhiza Bunge in the cell was evaluated through the examination of alkali phosphate(ALP) activity.Results:0.05%,0.10%,0.15% of Salvia Miltiorrhiza Bunge could enhance the cell proliferation rate(P

To investigate the influence of abnormal blood coagulating state on development of diabetic nephropathy. Methods Using radioimmunoassay and bivanlent antibody sandwich technic, the levels of plasma protein C (PC), platelet alpha-granule membrane glycoprotein (GMP-140), and factor Ⅷ: C and vWF were detected in 65 NIDDM patients and 15 normal controls. Results (1)PC level in microalbuminuric patients(DMⅡ) was significantly lower than that in normal controls and in normoalbuminuric patients (DMⅠ ), the lowest was in clinical proteinuric patients (DMⅢ); PC levels correlated negatively with urinary albumin exeretion rates(UAER). (2)The GMP-140 level was higher signifi-antly in DMn than in normal controls and in DMⅢ ; and the highest was in DMⅠ; the GMP-140 levels positively correlated with UAER. (3)There were negative correlations between PC and GMP-140、Ⅷ C-vWF. Conclusion A hyper-coagulable state occurs early in diabetic nephropathy as valuable indexes in reflecting the microangiopathy in diabetes.

Type 2 diabetic patients with the decline of urinary Tamm-Horsfall protein excretory rate showed the increment of fasting plasma homocysteine levels, suggesting that the damage of synthetic function of renal tubule may participate in the increment of homocysteine levels.

That there are so many difficulties in both of teaching and learning electrocar-diogram(ECG)is the characteristics in teaching and studying ECG. The following ways are the ef-fective methods of improving effects of classroom teaching of ECG:emphasizing the importance of ECG in clinical work at the beginning of the lecture on ECG in order that the students can understand the necessity of studying ECG and make up their mind to study ECG well;studying the teaching contents on ECG seriously and supplement the textbook appropriately;set up the link of discussion and create the condition that teacher and students work altogether;produce the slides with pictures(mainly)and words and give accounts of the pictures mainly;sum up the character-istics of all sorts of abnormal ECG and state the characteristics of presenting ECG simultaneously.

AIM: To explore the effects of high glucose a t fluctuant concentrations on glucose transport activity and expression of phosp hoinositide 3-kinase (p85) in primary cultured skeletal muscle cells. ME T HODS: Rat skeletal muscle cells were cultured at fluctuant glucose conce ntrations (5, 25mmol/L) for 48h. Then the glucose uptake and the expression of p hosphoinositude 3-kinase were measured. RESULTS: The skeletal mu s cle cells treated with fluctuant high concentration glucose showed the impairmen t of the basal and insulin-induced increase in glucose uptake and significant de crease in p85 protein expression as well as p85 mRNA. Particularly, there was a significant decrease in p85 protein and mRNA expression in the high fluctuate l evel of glucose concentration. CONCLUSION: The exposure to fluct uant high concentration of glucose inhibits glucose uptake and induces insulin r esistance in skeletal muscle cells.

Plasma VEGF level of T2DM was higher than that of normal control （NC, n=30） and progressively increases from normal albuminuria （NA, n=26） to microalbuminuria （MA,n=26） and to macroalbu-minuria （ODN, n=24） groups, The VEGF level was positively correlated with the levels of creatinine, HbA1c and UAER and, decreases after losartan treatment in groups of MA and ODN.

Objective To discuss the expression and the related factors of E-selectin in insulin-resistant(IR)rat endothelium. Methods Wistar rats were randomly divided into 3 groups: high fat feed,high fructose feed and the control feed(HF group,HG group and NC group). IR rat model was established by high fat feeding or high fructose feeding for 4 weeks and was evaluated with euglycemic clamp technique. E-selectin protein expression was detected by Western-blot analysis. Results The expression of E-selectin protein in vessel endothelium was increased in HF group and HG group compared with that in NC group (P<0.01), and higher in HF group than in HG group (P<0.05). E-selectin protein expression was correlated significantly with TG, FFA, FIns and HOMA-IR in HF group and HG group (P<0.05). Conclusions IR may cause the increased expression of E-selectin in endothelium of rats fed with high fat or fructose.

0.05).(4)The para-operation pulmonary function indexes(VC,VC%,FEV1)of the patients who had the variation of ECG were significantly lower than those of no-complication patients.(P

Objective:To observe expression and diversity of glycogen synthase (GSK)-3 and ribosome S6 protein kinase (P70S6K) in skeletal muscle of insulin resistance (IR) rat induced by high fat food and to approach the effect and significance of GSK-3 and P70S6K in IR occurrence.Methods:Forty Wistar rats aged four-week were randomly divided into normal control, high-glucose, high-fat and high-fat high-glucose groups. 8 weeks after feeding, insulin sensitivity of the rats was evaluated by hyperinsulinism euglycaemic clamps technique (ring clamp experiment), GSK-3 and P70S6K in rat skeletal muscle were measured by Western blot and epididymis fat pad weight, blood glucose, insulin, triglyceride (TG), cholesterin (TC), free fatty acids (FFAs) and hsCRP levels were also determined.Results:IR was induced, body weight (P
