Objective To observe the efficacy difference between nerve-trunk stimulation plus electroacupuncture at antagonistic points and the control group. Method Patients were randomized into group A (nerve-trunk stimulation plus electroacupuncture at antagonistic points), group B (electroacupuncture at antagonistic points), and group C (basic treatment), 45 cases in each group. The interventions were given once a day, 5 times a week, totally for 4 weeks. The changes of spasm degree and motor function of upper limb and activities of daily life were observed. Result After intervention, there were significant differences between group B and group C, and between group A and group B (P<0.05); there was a significant difference between group A and group C (P<0.01). Conclusion Compared to the control group, nerve-trunk stimulation plus electroacupuncture at antagonistic points can produce more significant efficacies in improving the spasm degree and motor function of upper limb and activities of daily life.

Objective To detect the expression of vascular endotheilal growth factor (VEGF), stromal cell-derived factor-1α (SDF-1α), and its receptor CXCR-4 in the retinopathy of diabetic rats, and to explore the relationship between those factors and diabetic-retinopathy(DR). Methods Diabetes was induced in 40 rats with a single intraperitional injection of streptozotocin(STZ). Experimental rats were randomly divided into M1 (diabetic for 1 month), M3 (diabetic for 3 months), and M5 (diabetic for 5 months) groups, and another 10 rats served as a normal control group (NC). Retinal vascular status was observed by transmission electron microscope. After retinal stretched preparation, VEGF, SDF-1α and CXCR-4 immunohistochemistry were done. Retinal VEGF, SDF-1α, and CXCR-4 mRNA were detected by semi-quantitative RT-PCR. Protein expression was measured by Western blot. Results Under transmission electron microscope, change in vascular status was found in M1 to M5 groups, but not in the NC group. The changes became increasingly serious with the prolongation of the disease. By immunohistochemistry, we found the expression of VEGF, SDF-1α, and CXCR-4 on the retina increased gradually. It increased after injecting STZ for 1 month and increased significantly after 5 months.VEGF, SDF-1α, and CXCR-4 mRNA expression increased obviously after injecting STZ for 1 month and increased significantly after 5 months. Western blot showed that protein of VEGF, SDF-1α, and CXCR-4 had no change after injecting STZ for 1 month. It began to increase in the M3 group and increased most in the M5 group. Conclusion The expression of VEGF, SDF-1α, and CXCR-4 on the retina in retinopathy of diabetic rats increases gradually with the prolongation of the disease. It is an important factor for diabetic retinopathy.

Object To investigate the relationship between plasma tumor necrosis factor ?(TNF-?) and insulin resistance in the patients with non obese type 2 diabetes.Methods The levels of plasma TNF-? and serum insulin were measured in 38 patients with type 2 diabetes and 30 healthy subjects by immuno-radioassay. Insulin sensitive index (ISI) and body mass index(BMI) were also calculated. The correlation analysis was done between TNF-? and ISI.Results ⑴ The levels of plasma TNF-? in type 2 diabetes were 30 79?6 64fmol/ml, and higher than those in controls (P
