Objective To investigate the protective effect and its mechanism of prescription Zu Zhong 1 Hao (a traditional Chinese medical prescription, including Astragalus membranaceus, Atractylodes macrocephala, Arisaema cure Bile, Rhizoma pinelliae, the seed of Prunus persiea , Angelica sinensis , Ligusticum Chuanxiong, Paeonia lactiflora , and Pueraria ,etc) pretreatment on focal cerebral ischemia-reperfusion in rats. Methods Sixty SD rats were randomly divided into sham-operation, ischemia-reperfusion, flunarizine and prescription Zu Zhong 1 Hao low-, medium-and high-dose groups (n=10 in each group). A rat model of focal cerebral ischemia-reperfusion was induced by suture method (ischemia for 3 hours followed by reperfusion for 24 hours). Nitric oxide (NO) was measured by the nitrate reductase method; superoxide dismutase (SOD) activity was assessed by the xanthine oxidase method; maiondialde-hyde (MDA) was determined by the thiobarbiturie acid method; and tumor necrosis factor-a(TNF-α) was detected by the enzyme-linked immunosorbent assay (ELISA) method. Results Prescription Zu Zhong 1 Hao significantly improved neurological deficits in focal cerebral ischemia-reperfusion in rats, reduced the content of NO and MDA in brain tissue, increased SOD activity, and down-regulated the expression of TNF-α. Among them, the role of the high-dose group was more significant (P<0. 01). There were also significant differences between the low-and medium-dose groups and the ischemia-reperfusion group (P<0. 05). Conclusions The pretreatment of prescription Zu Zhong 1 Hao has the protective effect on focal cerebral ischemia-reperfusion injury, and its mechanism may be associated with the decreased content of NO and MDA in brain tissue, increased SOD activity, and down-regulated TNF-α expression.

Objective To investigate the effect and safety of self-made blenderized diet used for nutritional support treatment in the ICU critically ill patients with diabetes. Methods 74 ICU critically ill patients with diabetes were randomly divided into two groups:study group and control group. The self-made blenderized diet were given to the patients in study group and enteral nutrition to the patients in control group for nutritional support treatment for four weeks. Then glucose metabolism, various nutrition indicators and gastrointestinal dysfunction were observed in these two groups. Results The fasting blood glucose and fructosamine levels were decreased significantly,while the nutritional indicators was significantly higher after treatment than at baseline in all patients. There was no significant difference in the levels of fasting blood glucose, postprandial glucose, fructosamine and nutritional indicators between two groups after treatment,so were the incidence of the hypoglycemia and gastrointestinal complications. Conclusion The self-made blenderized diet was a good enteral nutrition support therapy for ICU critically ill patients with diabetes which had a considerable effect, but more cheaper,and practical compared to the enteral nutrition emulsions.

The research aimed to investigate the therapeutic effects and mechanisms of Opuntia dillenii Haw polysaccharide (OPS) on atherosclerosis of rats. First atherosclerotic rat models were established by high-fat and high-calcium diet. Thirty days later, the rats were treated with low dosage of OPS (0.2 g x kg(-1) x d(-1)) or high dosage of OPS (0.4 g x kg(-1) x d(-1)) by intraperitoneal injection for 60 days continuously. At the end of treatment, thoracic aorta rings were prepared and vasorelaxation of rat thoracic aorta in different experiment groups were determined by using 620M multi wire myograph system in vitro. Blood and livers of rats were collected. Then plasma levels of total cholesterol (TC), triglyceride (TG) and low density lipoprotein (LDL) of rats were separately determined using whole automatic biochemical analyzer; protein level of hepatic apolipoprotein B (ApoB) and that of hepatic diglyceride acyltransferase (Dgat1) were measured by Western Blot technique. Results showed that the ability of rat thoracic aorta to relax decreased markedly in the model group compared with that in the normal group, and significant differences existed in vasorelaxation ratios induced by different concentrations of carbamylcholine chloride (Carb) between these two groups (P < 0.01). After OPS treatment, the ability of rat thoracic aorta to relax improved markedly, the vasorelaxation ratios induced by Carb at 5 and 10 μmol x L(-1) were respectively 0.34 ± 0.08 and 0.62 ± 0.15 in the group treated with low dosage of OPS, while the ratios induced by Carb at 1 and 5 μmol x L(-1) were respectively 0.54 ± 0.08 and 0.98 ± 0.02 in the group treated with high dosage of OPS, which were all significantly different with those in the model group (P < 0.01). Plasma contents of TC, TG and LDL reduced significantly by the treatments both with low and high dosages of OPS compared with those in the model group (P < 0.01). Protein level of hepatic ApoB and that of hepatic Dgat1 decreased significantly after the treatment with high dosage of OPS compared with those in the model group (P < 0.01). These results indicate that OPS can markedly improve the vasorelaxation of thoracic aorta of atherosclerotic rats and has significant anti-atherosclerotic effect; inhibiting the expression of ApoB and Dgat1 and thus decreasing the amounts of TC, LDL and TG serving as one of the molecular mechanisms of its antiatherosclerosis effect.
