OBJECTIVE:To study the improvement effects of baicalein against myocardial ischemia/reperfusion(I/R)injury in rats. METHODS:I/R injury model was induced by Langendorff method. Isolated heart of 40 rats were randomly divided into nor-mal group(continuous perfusion),model group(perfusion withdrawal 20 min)and baicalein high,medium and low concentration groups (K-H solution of baicalein 40,10 and 2.5 μmol/ml 10 min before perfusion withdrawal). The myocardial infarction rate, the activity of creatine kinase(CK)and lactate dehydrogenase(LDH)in coronary effluent liquid,SOD activity and MDA content, GSH/GSSG and apoptosis rate of cardiac muscle cell in myocardial tissue were detected. RESULTS:Compared with normal group, the myocardial infarction rate,apoptosis rate of cardiac muscle cell,the activities of CK and LDH and the content of MDA in myo-cardial tissue were increased in model group,while SOD activity and GSH/GSSG of myocardial tissue decreased(P<0.01). Com-pared with model group,the isolated myocardial infarction rate and the activities of CK and LDH in baicalein low and medium con-centration groups decreased,while SOD activity increased(P<0.05 or P<0.01);apoptosis rate of cardiac muscle cell and the con-tent MDA of myocardial tissue decreased significantly in medium concentration group,while GSH/GSSG increased (P<0.05 or P<0.01);those indicators had no significant change in high concentration group(P>0.05). CONCLUSIONS:Baicalein has cer-tain improvement effect on myocardial I/R injury in rats,and its mechanism may be associated with antioxidant and anti-apoptosis effect of baicalein.

Objective To investigate the prognostic significance of follicular lymphoma international prognostic index (FLIPI) and FLIPI2 in Chinese FL patients for better prognostic model.Methods 63 newly diagnosed FL patients who received rituximab plus CHOP (cyclophosphamide,doxorubicin,vincristine and prednisone)-like chemotherapy from January 2003 to December 2010 were retrospectively analyzed according to FLIPI and FLIPI2 scoring system.Results According to FLIPI,31 patients (49.2 ％) were stratified into the low risk group (0-1 point),24 (38.1％) into the intermediate risk group (2 points),and 8 (12.7 ％) into the high risk group (3-5 points).As for FLIPI2 scoring,17 cases (27.0 ％) were classified in low risk group (0 point),42 cases (68.3 ％) in intermediate risk group (1-2 points),and 4 cases in high risk group (3-5 points).The overall response rates and 2-year progression free survival (PFS) rates of the three risk groups were 93.5 ％ (29/31),91.7 ％ (22/24),75.0 ％ (6/8) (P =0.27),and 85.7 ％,75.2 ％,58.8 ％ (Log-rank =1.063,P =0.59) respectively in FLIPI.In terms of FLIPI2,the overall response rates and 2-year PFS rates of the three groups were 100.0 ％ (17/17),90.7 ％ (39/42),50.0 ％ (2/4) (P =0.01) and 92.9 ％,74.0 ％,33.3 ％ (Log-rank =7.075,P =0.03).Conclusion FLIPI2 presents more robust prognostic significance than FLIPI in disease progression perspective for FL patients treated with R-CHOP like regimens in this study.

Objective To examin and analyze the structure, ultrastructure and the circulation of the spleen ellipsoid in the soft-shelled turtle, Pelodiseus sinensis. Methods Twelve turtles were used and observed by light- and electron-microscopy and injection of ink suspension in this study. Results The spleen white pulp was consisted of the periarteriolar lymphatic sheath (PALS) and periellipsoidial lymphatic sheath (PELS). There was no lymphoid nodule in the spleen. Red pulp included splenic cords and splenic sinusoids. The marginal zone was not found in the turtle spleen. When the central arteriole left out of the PALS, it divided into several ellipsoid capillaries which were surround by the PELS. The end of the ellipsoid capillary opened directly to the splenic cord and the blood cells then entered into the splenic sinusoid through the gap between the endothelial cells. The ellipsoid capillary was consisted of simple cuboidal epithelium with an uncompleted basement membrane. The ellipsoid wall was consisted of supporting cells,ellipsoid-associated cells and reticular fibres. Lymphocytes and red cells were always found on the ellipsoid wall. After 40min of the injection of ink suspesion, much carbon particles of ink were restricted on the wall. Conclusion The ellipsoid capillary in the soft-shelled turtle, just like the high endothelial venule, was the important passage of the lymphocytes and blood cells going out and into the lymph tissue. The splenic circulation in the turtle belongs to the opening model.

Objective To investigate the effect of microcireulation blood flow and altering immunity by Chuanxiongqin,ulinastain and thymosin α1 on sepsis patients.Methods 90 patients were randomly divided into 3 groups(n=30),namely ICU group,Chuanxiongqin group,ulinastain and thymosin α1 group.HLA-DR/CD14+and IL-6,TNF-α,Lac,DD were measured.Results (1)DD showed no significant difference at every time point between ICU group and ulinastain+thymosin α1 group(P＞0.05).DD decreased in Chuanxiongqin group,and was significantly different from the others on the third day.(2)Lac unchanged significantly at every time point in ICU group(P＞0.05).Lac in Chuanxiongqin group and ulinastain+thymeain α1 group tended to decrease,and was statistically different from ICU group on the second day.(3)IL-6 and TNF-α tended to increase at every time point in ICU group(P＜0.05).In ulinastain+thymosin α1 group,IL-6 and TNF-α returned to the level before treatment,HLA-DR/(D14+increased significantly,and was higher than Chuanxiongqin group and ICU group statistically.Conclusion Chuanxiongqin could ameliorate circulation;ulinastsin and thymosin α1 could depress IL-6,TNF-α.So ulinastain and thymosin α1 might protect the immunity of sepsis patients.
