OBJECTIVE:To explore the effects of Compound Ligusticum chuanxiong drop pill on hemorheology and blood gas in model rats with diabetic nephropathy(DN). METHODS:60 rats were randomly divided into normal control group,model group, positive control group [Irbesartan tablet,0.013 g/(kg·d)] and Compound L. chuanxiong drop pill high-dose,medium-dose,low-dose groups [0.4,0.2,0.1 g/(kg·d)],10 in each group. Except for normal control group,rats in other groups were given high-sugar high-fat feed and intraperitoneally injected streptozotocin to reduce DN model. After 7 d modeling,rats in each group received relat-ed drugs intragastrically,once a day,10 mL/kg;normal control group and model group received equal volume of purified water in-tragastrically. After 64 d,hemorheology indicators [whole blood viscosity(high-shear,medium-shear and low-shear),plasma viscosi-ty,whole blood reduced viscosity] and blood gas indicators(carbon dioxide partial pressure,oxygen partial pressure,hemoglobin content,oxygen saturation,ratio of oxygenated hemoglobin to total protein) of rats were determined,hematoxylin-eosin staining was used to observe the pathological changes in kidney tissue. RESULTS:Compared with normal control group,hemorheology indi-cators and carbon dioxide partial pressure in model group were significantly increased(P<0.05 or P<0.01),oxygen partial pres-sure,hemoglobin content,oxygen saturation,ratio of oxygenated hemoglobin to total protein were significantly decreased(P<0.05 or P<0.01),with severe kidney damage. Compared with model group,except the improvement of carbon dioxide partial pressure, oxygen partial pressure,hemoglobin content in rats were not significant in Compound L. chuanxiong drop pill low-dose group,the above-mentioned indicators in other medicine groups were significantly improved(P<0.05 or P<0.01);the kidney tissue damage was improved to varying degree. CONCLUSIONS:Compound L. chuanxiong drop pill can significantly improve the hemorheology indicators of DN model rats,reduce blood viscosity,improve microcirculation and capacity of the blood to transport oxygen,and has certain improvement effect on kidney tissue morphology of DN rats.

Objective To study the effect of caveolin-1 on renal injury and the expression of tight junction proteins in MRL/lpr mice kidney.Methods The mice were divided into 4 groups:5 mice in the normal control group (BALB/c mice);the MRL/lpr lupus mice (n=18) were randomly divided into the MRL/lpr group in which 6 mice were included;the negative control group in which 6 mice were included;the caveolin1 transfection group in which 6 mice were included.The changes of urine protein,the levels of urea (BUN) and creatinine (Cr) were detected.The expressions of claudin-5,occludin,ZO-1 and caveolin-1 protein were determined by western bloting.Analysis of variance was used to determine statistical significant differences between the two groups.A significance level of 0.05 was considered as signigicant.Results Compared with the control group,24 h urine protein [(2 894±437) mg,(412±72) mg],BUN [(8.7±1.5) mmol/L,(6.9±0.4) mmol/L],Cr [(106±22) μmol/L,(85±4) μmol/L] were significantly increased,level of caveolin-1 protein increased (265±17,61±6),the level of occludin (114±12,190±12),claudin-5 (60±5,80±6) and ZO-1 (98±11,206±15) protein decreased in the MRL/lpr group (P＜0.05).After caveolin-1 transfection,the levels of urinary protein [(1 253±249) mg,(2 894±437) mg],BUN [(6.5±1.3) mmol/L,(8.7±1.5) mmol/L],Cr [(78±17) μmol/L,(106±22)μmol/L] were significantly decreased,and the levels of occludin (218±16,114±12),claudin-5 (87±6,60±5)ZO-1 (313±17,98±11) were increased (P＜0.05).Conclusion The expression of caveolin-1 protein in the renal tissues of lupus nephritis increases.Caveolin-1 can reduce the expression of tight junction proteins and contribute to progres-sion of lupus nephritis.
