  • The relationship between the diabetic retinopathy and the changes of erythrocyte deformability,erythrocyte membrane phospholipid and spectrin

    Objective To explore the relationship between the diabetic retinopathy (DR) and the changes of erythrocyte deformability(ED),erythrocyte membrane phospholipid and spectrin. Methods One hundred and eight patients with non-insulin dependent diabetes mellitus were divided into DR group(55 cases)and nonDR(NDR)group(53 cases).The changes of erythrocyte filtration index(EFI),erythrocyte membrane phospholipid and spectrin dimers(SP-D)and spectrin tetramers (SP-T)were measured in patients of DR and NDR groups and compared with the results of 53 cases of normal control group. Results The EFI,SP-D, SP-D/SP-T,sphingomyelin (SM) /phophatidylcholine(PC)were higher,and SPT,SM,PC,phophatidylserine(PS)and phatidylethanolamine(PE)were lower in patients with DR than those in control and NDR patients (F=8.467~18.925,q=6.845~12.627,Plt;0.001).The changes of all indicators in proliferative DR(PDR) patients were more obvious than those in background DR(BDR) patients(t=5,825-15.443,Plt;0.001).The EFI in DR patients was positively correlated to SM/PC,SP-D and SP-D/SP-T(Plt;0.01),negatively correlated to SM,PC,PE,PS and SP-T(Plt;0.01). Conclusions The decrease of ED caused by the abnormalities of erythrocyte membrane phospholipid and spectrin might participate in the occurance and development of DR,and correlated to the degree of pathologic changes.

  • The Effect of Oral Xiaoyan Lidan Tablets on The Bile Composition in Patients with Intrahepatic Bile Duct Stones

    ObjectiveTo observe the effects of oral Xiaoyan Lidan tablets(XYLDT) on the bile composition(total bile acids, cholesterol, phospholipids) in patients with intrahepatic duct stones after common bile duct exploration(CBDE) with T tube drainage, to explore its possible preventive effects on stone recurrence. MethodsForty consecutive patients with intrahepatic bile duct stones who underwent CBDE with T tube drainage were randomly divided into experi mental group and control group. XYLDT were administrated at day 4 after surgery in experimental group(n=20), while none of medication were given in control group(n=20). 2 mL of bile was collected through T tube in both groups at day 1, 2, 3, 7, 14, and 21 postoperatively. Total bile acids(TBA), cholesterol(CHO), and phospholipids(PLIP) in bile were measured, and TBA/CHO ratio and PLIP/CHO ratio were calculated respectively. The results were statistical analyzed. ResultsThe demographic data in both groups including age, gender, height, weight, preoperative concomitant diseases, operative time, postoperative complications, hospital stays, serum total bilirubin, direct bilirubin, alanine aminotransferase(ALT), aspartate aminotransferase(AST), and amylase were not significantly different(P > 0.05). The measurements of TBA, CHO, PLIP, and the ratio of TBA/CHO and PLIP/CHO in bile were not significant on day 1, 2, and 3 after surgery in both groups(P > 0.05). In experimental group, the TBA, CHO, and PLIP on day 7, 14, and 21 after surgery were significantly increased compared with the control group(P < 0.05). The ratio of TBA/CHO on day 7, 14, and 21 was 2.17±0.29, 2.29±0.44, and 2.59±0.58, the ratio of PLIP/CHO was 2.03±0.68, 2.84±0.64, and 2.86±0.77, respectively, which were also significantly increased compared with the control group(P < 0.05). ConclusionsOral XYLDT can increase the secretion of TBA, CHO, and PLIP, elevate the TBA/CHO and PLIP/CHO ratio, and change the bile composition which may increase the dissolution of cholesterol in the bile. Presumably, oral XYLDT may have preventive effects in the recurrence of intrahepatic bile duct stones.
