The effect of TRH on endotoxic shock in rats was studied, iv 0. 22-2 mg ?kg-1 TRH significantly reversed hypotension induced by iv coli E. endotoxin (40 mg ?kg-1) into rats and caused a 4. 2 kPa rise in mean arterial pressure (MAP). MAP after TRH administered could be stablized over a higher level than control for 30 min and maintained for 3 h during observation. Interestingly enough, the MAP rose gradually in TRH-treated rats as contrast with increasingly falling of that in control group during the late shock. TRH also improved 24 h sur-vival of shock rats. The dose-response relationship could be observed between 0. 22 ~0. 67 mg ?kg-1 TRH and disappeared over a highest dose (2 mg ?kg-1). It was shown that the best dose to reverse hypotension and to improve survival was 0. 67 mg ?kg-1 TRH. Naloxone 2 mg ?kg-1 showed the nearly same effect as 0. 22 mg ?kg-1 TRH in increasing MAP, but the former had higher 24 h survival of rats than the later.

Objective To investigate the relationship between blood biochemical indicators levels (glycosylated hemoglobin and serum bilirubin) and atherosclerosis in elderly type 2 diabetic.Methods Totally 100 type 2 diabetic patients aged 62-85 years were divided into type 2 diabetes mellitus with carotid atherosclerosis group (T2DM-AS group,n=55) and type 2 diabetes mellitus group (T2DM group,n=45).Blood biochemical indicators levels (glycosylated hemoglobin and serum bilirubin) were determined and compared between the patients and the healthy controls (n=60)Results Serum levels of total cholesterol,triglyceride,low-density lipoprotein and Lp(a) were elevated in T2DM-AS group as compared with T2DM group [(5.86 ± 0.28) mmol/L vs.(4.63 ±0.32) mmol/L,(2.02±0.43) mmol/L) vs.(1.56±0.39) mmol/L,(3.74±0.76) mmol/L vs.(3.03±0.81) mmol/Land (297.3±102.2) mmol/Lvs.(203.5±110.4) mmol/L,t=20.91,5.54,4.51 and 4.40,all P＜0.05].Glycosylated hemoglobin level was higher in T2DM-AS and T2DM groups than in control group [(9.58 ± 0.47) mmol/L,(7.21 ± 0.66) mmol/L vs.(5.31 ± 0.54)mmol/L,both P＜0.05].There was a significant difference in glycosylated hemoglobin level between T2DM-AS group and T2DM group [(9.58 ± 0.47) mmol/L vs.(7.21 ± 0.66) mmol/L,t=20.9,P＜0.05].Serum bilirubin level was lower in T2DM AS group than in T2DM and control groups [(8.02±1.23)μmol/L vs.(13.72±1.64)μmol/L,(19.66±1.41)μmol/L; t=19.8,47.0,both P ＜0.05].Conclusions Glycosylated hemoglobin and serum bilirubin may promote atherosclerosis in elderly type 2 diabetic.The control of glycosylated hemoglobin and blood lipids levels may help to reduce atherosclerosis in elderly type 2 diabetic patients,which has the important clinical significance for the prevention and treatment of type 2 diabetes mellitus.

Objective To study the effect of cumulus cell apoptosis on the structure of human oocyte cultured in vitro and to probe into the reason why cumulus cell apoptosis rate can be used clinically to predict the developmental potential of oocyte. Methods Cumulus-enclosed oocyte complexes (COCs) at the GV stage were cultured in vitro. The apoptosis rate of cumulus cells for every COC was evaluated with HE staining, DAPI staining and TUNEL labeling methods. Oocytes were divided into two groups according to their cumulus cell apoptosis rate. Structure of oocytes was observed under light microscope and transmission electron microscope. Mature oocytes at MⅡ stage were fertilized and cultured in vitro for two days. Then the embryos were evaluated according to their morphology under light microscope.Results The oocytes with low cumulus cell apoptosis rate had a normal structure and a promising developmental potential, while the oocytes with high cumulus cell apoptosis rate had deformed structures and a poor developmental potential. Some deformed oocytes had uneven perivitelline space. For oocytes with a small perivitelline space, the organelle development was slow compared with those with a large perivitelline space. Some had unevenly piled organelles. Secondary lysosomes and large space probably caused by the decopmounding of lysosomes were found in the ooplasm of these oocytes. The deformed oocytes appeared to have lots of swollen mitochondria with blurred cristae and membrane. Some of these oocytes had fractured first polar bodies and abnormally thick or thin zona pellucida. The cell junctions and microvilli of cumulus cells reduced as well. Conclusion The effect of cumulus cell apoptosis on the structure of oocyte cultured in vitro was revealed. The reason why cumulus cell apoptosis rate prognosticated the developmental potential of oocyte was demonstrated in the aspect of oocyte structure.
