ABSTRACT
Objective To investigate the effect of PGC-1 on hepatic glucose metabolism of type 2 diabetes by observing its changes in the liver of OLETF rats. Methods OLETF rats were observed,even-aged LETO rats were controled. Oral glucose tolerance test, Fasting Insulin, triglyceride and total cholesterol were measured and then the protein level of PGC-1 , phosphoenolpyruvate earboxykinase and uncoupling protein 2 of liver tissue were detected by Western blot respectively in 8,18 and 28 weeks. Results (1)OLETF rats had significantly higher levels than LETO rats, in body weight, OGTT2h blood glucose and TG at 18th, 28th week. The levels of Fasting Insulin of OLETF rats were higher while insulin sensitive index were lower than that of LETO rats at 28th week. (2)Protein expressions in the livers: PGC-1 of OLETF rats was lower than that of LETO rats at 18th and 28th week. PEPCK of OLETF rats was more while UCP2 was lower than that of LETO rats at 28th week. Conclusions OLETF rats showed pathological phenotypes of type 2 diabetes. The changes of PGC-1 , PEPCK and UCP2 in 28-weeks OLETF rat suggested that PGC-1 plays an important role in the liver glycometabolism in type 2 diabetes.
ABSTRACT
The technique of minimally invasive embedding simplifies the clinical manipulation of embeddingtherapy and relieves painful patients. The safety of minimally invasive embedding is analyzed in terms of manipula-tion apparatuses, embedding materials, operating techniques and possible adverse reactions, etc. It is expected thatthe evidence of popularizing minimally invasive embedding should be provided.

Total knee replacement surgery is commonly used in end-stage diseases of the knee. It is important for improving surgical efficacy and patient satisfaction by promoting early rehabilitation of patients and improving knee function.
ABSTRACT
Seventy cases were classified into wind-cold and wind-heat on the basis of syndrome differentiation. Acupoints of Yangming meridians of both hand and foot and points located in the face, including major points: Yangbai (GB 14), Cuanzhu (BL 2), Jingming (BL 1),Chengqi (ST 1), Dicang (ST 4), Jiache (ST 6), Juliao (ST 3), and Hegu (LI 4). Subcutaneous needling is applied. Recovery rate is 91.4%
ABSTRACT
Objective To observe the effect of long snake moxibustion on adjuvant arthritis rats, and explore its mechanism in treating rheumatoid arthritis. Methods Forty-eight Wistar rats were randomly divided into normal control group, model group, drug group and moxibustion group, 12 rats in each group. The model of adjuvant arthritis rats was induced by intracutaneously injection of complete Freud's adjuvant in the right hind foot pat of rat. Three days later, the medcine group was given Wangbi Keli, and the moxibustion group was treated with long snake moxibustion. The changes of toe swelling was observed, and the content of IL-1, TNF-a and IL-10 in serum were detected by radioimmunoassay (RIA). Results Long snake moxibustion can relieve toe swelling and decrease the level of IL-1 and TNF-p in serum (P
ABSTRACT
Objective:To explore the possible molecular mechanism of abnormal renal lipid metabolism in OLETF rats, and the effects of fenofibrate or metformin on renal local lipid metabolism. Methods: OLETF rats were randomly divided into three groups:one treated with fenofibrate, one with metformin and one without treatment. LETO rats were used as age-matched normal controls. The animals were sacrificed and the kidneys were obtained respectively at the age of 17 and 30 weeks. 24-hour urine albumin contents and TG contents in renal cortex were measured. The levels of SREBP-1 protein and mRNA in kidney were measured. FAS mRNA and ACC mRNA expressions were measured with RT-PCR. Results:OLETF rats showed characters of obesity, hyperglycemia, hyperlipidemia. At the end of thirty weeks clinical characters of renal damage appeared in OLETF rats, OLETF rats showed higher levels of 24-hour urine albumin contents than those of LETO rats. 24-hour urine albumin contents were correlated positively with TG contents in kidney. The partial correlation coefficient was 0. 870(P = 0.011) by controlling for body weight, serum lipid, blood glucose and fasting insulin concentration. OLETF rats showed higher levels of SREBP-1 protein (43. 2% , P
ABSTRACT
Objective: To explore the exact role of ghrelin in glyco-and lipo-metabolism.Methods: We compared the levels of ghrelin mRNA in gastric tissue,ghrelin in gastric tissue and plasma among LETO rats(non diabetes,n=10),OLETF rats(type 2 diabetes,n=10),OLETF/M rats(OLETF rats managed with Metformin at the dose of 100 mg/kg weight,n=10) and OLETF/F rats(OLETF rats managed with Fenofibrate at the dose of 20 mg/kg weight,n=10).The levels of ghrelin mRNA were tested by Northern blotting,and the ghrelin content in gastric tissue and plasma detected by RIA.Results: At the age of 30 weeks,the ghrelin fasting plasma levels of OLETF rats were lower than those of LETO rats(37.49?6.42 vs 58.52?5.85,P0.05).However,the fasting blood plasma ghrelin levels of OLETF/F group were more than those that of the untreated OLETF rats(62.02?7.35 vs 37.49?6.42,P
