Objective To compare the effect of different cryoprotectants and different concentrations on controlled?rate freezing of human ovarian tissues. Methods Ovarian tissues were sampled from 15 patients undergoing benign ovarian tumor surgery. Cortical slices were frozen by controlled?rate freezing using three cryoprotectants,propanediol,ethanediol,and dimethylsulphoxide,and the concentration of each cryoprotectant was 1.5 mol/L or 2.0 mol/L. Cortical slices obtained from each patient were processed with each cryopreservation procedure simultaneously. Morphology of fol?licles was studied by light and electron microscopy and the normal rate was compared with that of the fresh tissues from the patient. Results There were no significant differences in distribution of follicles of different developmental stages between each group(P<0.05). Light microscopy showed 1.5 mol/L EG and 2.0 mol/L EG groups had the best freezing effect,and the difference in the morphologically normal rate of follicles was not statisti?cally significant compared to fresh controls(P>0.05). However,the difference was statistically significant for 1.5 mol/L PROH,2.0 mol/L PROH, 1.5 mol/L DMSO and 2.0 mol/L DMSO groups(P<0.05). Electron microscopy showed the oocyte quality declined after controlled?rate freezing pro?cedure. However,the statistical analysis was not conducted due to little data. The viability of granulosa cells was significantly declined after all the freezing procedures compared to that of the fresh control tissues(P<0.01). The number of morphologically normal granulosa cells was slightly higher in the tissues which had been cryopreserved with 2.0 mol/L PROH and 1.5 mol/L EG,but no significant differences were found between any of two frozen groups(P>0.05). Conclusion Controlled?rate freezing using 1.5 mol/L EG as the cryoprotectant can better save oocytes and granulosa cells. It is a preferable freezing procedure for ovarian tissues.

Objective To observe the correlation between lipoprotein-associated phospholipase A2(Lp-PLA2) levels and coronary artery disease (CAD), extent of angiographic coronary artery lesions and risk factors of CAD in the elderly. Methods Plasma levels of Lp-PLA2, triglyceride (TG), total cholesterol(TC), low density lipoprotein(LDL-C), high density lipoprotein cholesterol (HDL-C) and high sensitivity C-reactive protein(hs-CRP) were measured in 67 elderly patients with angiographic CAD meanwhile in 23 normal controls without angiographic coronary artery lesions. The extent of coronary artery lesions was evaluated according to the number of vessel lesions (divided into single, double and triple-vessel lesions) and Gensini scoring system. Then the relationship between Lp-PLA2 and CAD was assessed. Results The plasma levels of Lp-PLA2 were significantly higher in the CAD group than in the controls [(352.7 ± 129.0) vs. (204.0 ± 59. 7) μg/L, P < 0. 01]. Lp-PLA2 levels increased with the number of coronary artery lesions and Gensini score, then were positively correlated with age(r= 0. 25, P<0. 05) ,TC(r=0. 33, P<0. 01) ,LDL-C(r=0.27, P< 0. 05),apoB(r=0. 36, P<0. 01). The levels of LP-PLA2 and LP(a) were associated with CAD by using stepwise regression analysis. Conclusions In the eldly, the levels of LP-PLA2 are much higher in angiographic CAD, and these may reflect the severity of CAD. LP-PLA2 is a risk factor for CAD.

Objective: To study the hypoglycemic activity of polysaccharides from Tremella aurantialba mycelium (TMP). Methods: The anti-hyperglycemic effect of TMP was investigated in normal mice and diabetic rats induced by alloxan in comparison with phenformin and acarbose. Results: TMP not only decreased serum glucose level in normal mice, but also in diabetic rats. After i.g.TMP to hyperglycemic rats for 1w, the glucose and TG in serum were decreased obviously , but serum TC did not change remarkably. After i.g. 100 mg/(kg ?d) TMP to hyperglycemic rats for 23 d, liver glycogen and BLA did not change significantly, but serum glucose was reduced obviously compared with the control . Conclusion: TMP has obvious hypoglycemic activity and can reduce hyperlipemic complications.

Objective To explore mood disorders after left and right cerebral hemisphere injury,to search for possible mechanisms and to provide the basis for designing rehabilitation protocols and assessing prognosis.Methods Fifty-one cases with brain injury were recruited from a rehabilitation center and divided into left and right hemisphere injury groups with 26 and 25 cases,respectively.Hamilton rating scale for depression (HRSD) scores were analyzed. Results The left hemisphere patients had significantly higher HRSD total scores and higher scores indicating 15 kinds of mood disorders (depression,feelings of guilt,suicidal thoughts etc.).Right hemisphere injury patients had significantly higher diurnal variation,depersonalization or derealization and paranoid symptoms. Conclusions The lateralization of the cerebral hemispheres may display itself in mood and emotion.After left or right hemisphere injury,the depression presentation is different,so treatment,prognosis assessment and psychological intervention should be different for left and right hemisphere injuries.
