OBJECTIVETo observe the effects of taurine on hemorheology and oxidative stress of diabetic rats.

METHODS40 rats were divided into control group, diabetes group and treatment group at random. Diabetic model was reproduced by intraperitoneal injection of streptozotocin. After having been treated with taurine for 8 weeks, glycosylated hemoglobin (HbA1c) and the serum contents of glucose, superoxide dismutase(SOD), malondialdehyde (MDA) were measured. The changes of hemorheology in different groups were detected respectively.

RESULTSCompared with control group, the content of glucose, MDA and HbA1c in diabetic rats was increased, the activity of SOD was decreased, the levels of whole blood viscosity and the aggregation index of red blood cells and hematocrit were increased and RBC deformability index was decreased in diabetic rats. Moreover, taurine was able to apparently reduce high blood glucose and HbA1c (P < 0.05), markedly elevated the activity of SOD, lowered the content of MDA (P < 0.01); and taurine also could significantly reduce the levels of whole blood viscosity and the aggregation index of red blood cells and hematocrit in the meanwhile, and increase RBC deformability index (P < 0.05 or P < 0.01).

CONCLUSIONTaurine could enhance the ability of oxidation resistance, improve blood rheology property in diabetic rats, at the same time it could be beneficial to prevent and cure the development of diabetic blood vessel complication.

OBJECTIVETo probe into an effective method for treatment of endometriosis (EMs) and the mechanism.

METHODSRat EMs model was established and they were randomly divided into a model group, an acup-moxibustion group, a TCM group, an acupuncture and medicine group, with a control group set. The acup-moxibustion group were treated with electroacupuncture at "Xuehai (SP 10)", "Sanyinjiao (SP 6)" and moxibustion at "Guanyuan (CV 4)"; the TCM group were treated with stomach perfusion of modified Mojie Tablet in normal saline; the acupuncture and medicine group were treated with the above two methods; both the control group and the model group were bound and treated with stomach perfusion of saline. After treatment of 35 days, the greatest diameter of the ectopic tissue was measured in the rats, pathological observation of the ectopic tissue was made and matrix metalloproteinase-2 (MMP-2) expression in the ectopic tissue was determined.

RESULTSThe greatest diameter of ectopic tissue and MMP-2 expression in the ectopic tissue in the acupuncture and medicine group were significantly lower than those in the model group, the acup-moxibustion group and the TCM group (P < 0.05); and the ectopic endometrium trended to atrophy, and with necrosis of some epithelial cells.

CONCLUSIONCombination of acupuncture with medicine has a better therapeutic effect on endometriosis and down-regulates the abnormal increase of MMP-2 level to inhibit the invasion of ectopic tissue to extracellular matrix, so as to reduce the ectopic tissue, hence cure of endometriosis.

AIMTo study the effects of PKC activation on apoptosis during ischemia/reperfusion in L-6TG rat skeletal myoblasts.

METHODSCultured L-6TG cells were divided into 3 groups: control group (C), ischemia/reperfusion group (I/R), PMA + ischemia/ reperfusion group (PMA), SOD, XOD and free calcium and mitochondrial respiration in L-6TG cell were evaluated in each group. Apoptosis was detected by flow cytometer with PI staining method and agarose gel electrophoresis, the immunohistochemical method was used to determine the expression of caspase-3.

RESULTSCompared with I/R group, in PMA group, XOD , free calcium in L-6TG cell and apoptotic percentage all decreased significantly, while SOD and mitochondrial respiration in L-6TG cell increased. DNA fragmentation analysis of L-6TG cell showed no laddering pattern. The expression of caspase-3 was down regulated significantly.

CONCLUSIONActivation of PKC can lessen ischemia/reperfusion injury and apoptosis through lessening oxidative injury and mitochondrial injury, adjusting calcium dyshomeostasis and down expression of caspase-3.

AIMTo investigate the effect of pretreatment with taurine on liver injury changes and the change of tumor necrosis factor alpha and NFkappaB expression following rats limbs ischemia/reperfusion.

METHODSThe model of limbs ischemia/reperfusion injury on rats was adopted in the experiment. Wistar rats were randomized into 4 groups (n = 10): Control group, T group, I/R group and TR group. Levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST) and MDA in the plasma, MDA, MPO, calcium in liver tissues were measured by colorimetric method. The content of TNF-alpha in plasma and liver tissues was determined by radioimmunoassay. The morphologic changes were observed with HE staining. The expressions of NF-kappaBp65 in liver tissues were tested by immuno-histochemistry method.

RESULTSIt was found that against the control group, the test values of ALT, AST, et al. and expressions of TNF-alpha, NF-kappaB increased in I/R group and TR group, but values of those in TR group were lower than in I/R group.

CONCLUSIONTaurine can decrease the levels of TNF-alpha and NF-kappaB. It can mitigate the liver injury after limb ischemia/reperfusion injury in rats.
