Objective To examine the effect of hydroxyethyl starch (HES 6%, 200/0.5) on reticuloendothelial system (RES) function in hemorrhagic shock. Methods Thirty 8 to 12-week-old Wistar rats weighing 250-350g were randomly divided into two groups: HES group ( n = 15) and control group ( n =15) . The animals were anesthetized with intraperitoneal 0.5% pentobarbital sodium 30mg ?kg-1 Bilateral common carotid arteries were exposed and cannulated for MAP monitoring and blood-letting. Blood was gradually removed until MAP dropped to 40mm Hg, which was maintained for 60min. Then same amount of HES (HES group) or Dextran (control group) was infused. The Kupffer cells were separated and purified before hemorrhagic shock (T0), at 12h (T1) 24h (T2) 48h (T3) and 72h (T4) after HES or DEX infusion, when the animals recovered from shock. Phagocytic activity of Kupffer cells (KC) was measured by counting the amount of Latex particles ingested by KC. Results At the same intervals (T1-4) there was no significant difference in phagocytic activity of KC between the two groups. There was no significant difference in phagocytic activity of KC between T0 (baseline) and T1-4 in both groups.Conclusions The phagocytic activity of Kupffer cells in not affected by removed of 20-30% blood volume which was replaced by same amount of HES.

OBJECTIVE: To investigate the absorption characteristics of dauricine in rat intestine. METHODS: In situ single-pass perfusion model was used and the concentrations of dauricine in perfusate were determined by HPLC. The effects of perfusion rates, intestinal segments and drug concentrations on the intestinal absorption of dauricine were studied. RESULTS: The absorption rate and absorption degree of dauricine increased with the perfusion rates(0.1, 0.2 and 0.4 mL · min-1)(P<0.05); the absorption rate constants of dauricine in duodenum, jejunum, ileum and colon were not significantly different(P>0.05); at high, middle and low concentrations, the drug absorption rate constants(Ka) were (2.36±0.0073) × 10-2, (3.73 ± 0.0052) × 10-2 and(5.62 ± 0.0136) × 10-2 min-1, respectively, the apparent permeation coefficients(P.,) were(2.02±0.0002) × 103, (3.10±0.0007) × 10-3 and (5.31±0.0010) × 10-3 cm · min-1, respectively, the absorption percentages(P%) were 8.66%, 10.17% and 19.06%, respectively, and the accumulate absorption amount and accumulate absorption percentages of different concentrations at different time were very low. CONCLUSION: The absorption degree of dauricine increases with perfusion rates; there is no specific absorption site in the whole rat intestinal tract; the absorption of dauricine is very poor and the active transport is involved in the absorption mechanism of dauricine.

ObjectiveTo assess the relationship between the location,quantity and leukodystrophy of cerebral infarction and vascular cognitive impairment ( VCI ),and to compare the differences of the severity and domains of cognitive impairment among the different types of cerebral infarction,which will provide the pathophysiological evidence to the mechanism for the development of VCI. MethodThe patients suffering from cerebral infarction or leukodystrophy were recruited from either the ward or clinic in Tianjin General Hospital from April 2009 to April 2010,then assessed the cognition,and classified into different groups according to the location,size,quantity,whether or not they have leukodystrophy and the severity.The Logistic regression analysis was taken with whether or not the patients have had developed to the VCI as the dependent variable,and with the location,size,quantity,whether or not they have leukodystrophy and the severity as the independent variables.The differences of the score of NIHSS,Bathel index and the level of cognitive impairment were compared among patients with different types of lesions.Moreover,the difference of the score of MoCA for each cognitive domain were compared among patients with different types of lesions.ResultsThere was a relationship between key position infarction in the subcortex and white leukodystrophy with VCI.The position infarction in the subcortex and white leukodystrophy ( grade Ⅱ and Ⅲ ) might be the independent risk factors for the VCI( OR =1.752,2.135,3.753; 95％ CI 1.533-3.821,1.541-6.787,1.432-6.821,all P ＜0.05).There were significant differences in the domains of excusive ability,attention,calculation,fluent language and orientation.The average scores of the domain of excusive ability in the subcortical group (3.40 ± 1.90) and the mix group (3.83 ± 1.27) were significantly lower than the cortical disease group(4.28 ± 0.89,t =0.050,0.857,both P ＜ 0.05 ).The average scores of the domains of attention,calculation,fluent and orientation in the mix group were significantly lower than the subcortical group and cortical disease group.ConclusionsThere is a significant association of the key infarction in the subcortex and leukodystrophy with VCI.The patients with both the subcortex infarction and leukodystrophy are susceptible to VCI.The development of VCI is depended on the position of infarction instead of the quantity and size of infarction.The development of VCI is not only related to the white matter disease but also related to the severity of the leukodystrophy.The data highlights the need to small vessel disease.The patients with subcortical lesions mainly impair the executive ability.The patients with mix lesions may have more extensive domains and more severe cognitive impairment.

Objective To Observe the influence of Zaoshi Jiedu Zhupi Sanjing (ZPSJ) Recipe on insulin sensitivity, serum resistin and inflammatory factors related to the effects of Chinese herbal compound in type 2 diabetic patients with insulin resistance. Methods A single-blind randomized controlled clinical trial was conducted. 80 patients with 2 type diabetic patients with insulin resistance were recruited into a control group and a treatment group. The treatment group was treated with ZPSJ Recipe, and the control group was treated with metformin. Results In each group before and after treatment: blood glucose, serum insulin levels, HOMA-IR were significantly decreased (t=7.14, P<0.01 ) ; between the two groups, FPG, FINS showed no significant difference, while TG TCH, HOMA-LR showed significantly differences (t=2.62, P <0.05 ). Within the two groups before and after the treatment: serum IL-6, TNF-a, hs-CRP were decreased in treatment group, (t= 1.85, P<0.05 ) , while TNF-a, hs-CRP were decreased in the control group (t=2.56, P<0.05 ) , while IL-6 did not change significantly. The serum resistin levels were not statistically changed in both groups before and after treatment. Conclusion ZPSJ Recipe can regulate blood sugar, blood fat and improve insulin sensitivity in type 2 diabetic patients with insulin resistance.

Erythropoietin(EPO) has an anti-apoptotic effect,and promotes the proliferation and differentiation of erythroid progenitor cells. Several studies have indicated that EPO can protect photoreceptor cells from the lightinduced retinal degeneration ;protect retinal neurons from ischemia-reperfusion injury and retinal ganglion cells after acute and chronic ocular hypertension; promote ganglion cell survival and axonal regeneration after optic nerve transaction; attenuate inflammation in multiple sclerosis optic neuritis; reduce the permeability of the retinal barrier and protect retinal neurons in diabetic retinopathy; enhance the stability of hypoxic retinal vessels in retinopathy of prematurity. Herein,we review the distribution of EPO and its receptor in retina,their expression in animal model of retinal diseases,and their effects and mechanisms in protection of retinal neurons and optic nerve.
