The establishment of diabetic peripheral neuropathy model in spontaneous diabetic GK rats / 天津医药

Objective To establish a simple diabetic peripheral neuropathy (DPN) rat model with the high fat-fed in GK rats. Methods A total of 30 GK rats (7-8 weeks) were fed with high-fat diet to establish the DPN model. Thirty normal Wistar rats were fed with ordinary diet (control group). The blood-sugar value, body mass, water-intake and food-intake were monitored every week in two groups. The serum level of glycosylated hemoglobin, the right sciatic nerve conduction velocity were detected at 8, 12 and 16 weeks respectively. The left sciatic nerve was used for HE and TUNEL staining. Results The manifestations of polydipsia, polyphagia and growth retardation were gradually appeared in GK rats. After 12 and 16 weeks, the blood-sugar and glycosylated hemoglobin were significantly increased in GK rats compared with those of normal Wistar rats (P 0.05). The sciatic nerve pathological features and Schwann cell apoptosis suggested that the model of DPN was successfully established (apoptosis index, P <0.01). Conclusion GK rats fed by high-fat diet are the satisfactory models of the DPN in experimental research. And 12-week is a suitable and economical time for molding.

Clinical Observation of Warm Needling plus Chinese Medicinal Fumigation and Rehabilitation Training for Post-stroke Shoulder Pain / 上海针灸杂志

ObjectiveTo observe the therapeutic efficacy of warm needling plus Chinese medicinal fumigation and rehabilitation training in treating post-stroke shoulder pain.MethodSixty eligible patients were randomized into a treatment group (warm needling plus Chinese medicinal fumigation and rehabilitation) and a control group (rehabilitation training), 30 casesin each group. The Visual Analogue Scale (VAS), Fugl-Meyer Assessment Scale (FMA) and Barthel Index (BI) were respectively used to evaluate pain intensity, upper-limb motor function and activities of daily living, and the clinical efficacies were compared between the two groups.ResultAfter 30-day treatment, the improvements of shoulder pain intensity, upper-limb motor function and activities of daily living in the treatment group were more significant than that in the control group (P<0.05). There were no adverse events happened in the two groups.ConclusionWarm needling plus Chinese medicinal fumigation and rehabilitation training can effectively and safely mitigate shoulder pain, improve upper-limb motor function, and enhance the activities of daily living, and its therapeutic efficacy is superior to that of the control group.
