RESUMO
Objective To observe the effects of Chinese herbal compounds (alkaloid of Coptidis Rhizoma 40%, total saponin of panax notoginseng 35%, and polysaccharide of Ophiopogonis Radix 25%) on levels of blood glucose, fructosamine, and insulin of diabetic rats, and explore mechanism of action.Methods Ten rats were randomly chosen as blank control group, and other rats were used to establish diabetic rat models by STZ intraperitoneal injection. Successfully molding rats were randomly divided into Chinese herbal compounds high, medium, low dose groups, metformin group, and model group, 10 rats in each group. Each rat received gavage for continuous 4 weeks. Then rat blood was collected by cutting head and taking caudal vein. FBG was detected by glucose oxidase method;insulin level was detected by radio-immunity double antibody method;fructosamine content was detected by fructosamine method.Results Compared with the blank control group, model group the levels of FBG, froctosamine content increased, while fasting insulin level were lower after 4 weeks'medication. Compared with the model group, the levels of FBG, froctosamine content in Chinese herbal compounds high and medium dose groups and metformin group were lower, while fasting insulin level increased after 4 weeks'medication (P<0.05).Conclusion TCM herbal compounds can increased the basic insulin level by decreasing the contents of FBG and fructosamine.
RESUMO
Objective To investigate the influence of bifidobacterium on inflammatory response of brain traumatic injury patients.Methods According to the sequence of patients'admission time,a total of 60 patients with traumatic brain injury were randomly divided into the research group and the control group,30 cases in each group.The research group was fed intestinal nutrient solution combined with bifidobacterium,and 1 × 108cfu/d bacteria every day.The control group was skimpily given enteral nutrient solution.The WBC counts,C-reactive protein (CRP) and interleukin-6 (IL-6),GCS score and infection status,ICU length of stay and 30 days mortality in the 1 st,5th,10th,15th day of enteral nutrition were recorded by health care professionals.Results The leukocyte count,CRP and inflammatory factors IL-6 of the research group were significantly lower than those in the control group in the 15th day of enteral nutrition[(8.02 ± 2.47) × 109/L vs (10.54 ± 3.98) × 109/L,(28.02 ± 9.43) mg/L vs (70.54 ± 13.92) mg/L,(61.02 ± 22.43) ng/L vs (83.52 ± 14.94) ng/L; t =5.474,6.231,9.343,P =0.029,0.049,0.001] ;The GCS score of the two groups gradually increased,and which of the first 10 days had no significant differ ence between the two groups.In the 15th day of enteral nutrition,GCS score of the research group was significantly higher than the control group [(12.02 ± 2.12) point vs (10.12 ± 4.94) point,t =9.744,P =0.000].The incidence rate of infection of research group was significantly lower than that of the control group,but ICU length of stay shortened (16/30 vs 27/30,x2 =9.610,P =0.002).No significant difference was observed in 30-day mortality between the two groups.Conclusion Adding an appropriate amount of probiotics in enteral nutrition on regular basis can significantly reduce the body's inflammatory response and the incidence of infection in patients,shorten hospitalization days.
RESUMO
This paper discussed the random growth model of the capillaries in its growing process, analyzed the relations between the growth of the capillaries, the metabolism of the organism tissue, and micro environmental condition and secretion of the growth factors. Furthermore, the paper discussed the growth law of the capillaries in the porous silk fibroin films (PSFF) in order to provide a theoretical basis for the designing and making of the new biomaterial of the PSFF more suitable for the growth of the cells and capillaries.
