Objective To study the anti-tumor effect of tenacissoside H on Lewis lung cancer mice, and explore its impacts on immune function of tumor-bearing mice. Methods Mice was injected Lewis lung cancer cells subcutaneously to the right axilla. Thirty successful tumor-bearing mice were randomly divided into model group, the cyclophosphamide (CTX) group and tenacissoside H group, 10 mice in each group. Three days after inoculation, mice were intraperitoneally injected by normal saline, CTX and tenacissoside H respectively every two days, 0.2 mL in each mouse. On the 21st day, the eyeballs were extracted and blood was drawn, tumor tissue, spleen and thymus were taken and weighted to calculate tumor inhibition rate, spleen index and thymus index, and the contents of IL-2 and IL-10 were detected by ELISA. Results The tumor weights of CTX group and tenacissoside H group were lower than that of the model group with significant difference (P<0.05), and the tumor inhibition rates were 54.12%, 25.68%. The thymus index and spleen index of tenacissoside H group increased, but that of CTX group decreased significantly. Compared with the model group, the IL-2 level of tenacissoside H group was significantly increased, while the IL-10 level decreased. Conclusion Tenacissoside H can inhibit growth and metastasis of Lewis lung cancer, regulate the expression of IL-2 and IL-10, and improve the immune function of tumor-bearing mice.

Objective Acute respiratory dysfunction (ARD) can occur after aortic surgery with the use of cardiopulmonary bypass and deep hypothermic circulation arrest, but relatively little is known about acute respiratory dysfunction in the patients with type A aortic dissection. This study aims to analyze the independent risk factors of acute respiratory dysfunction after A type aortic dissection surgery and to assess possible prevention and treatment option in the future. Methods Clinical data of the 252 patients including 193 male patients and 59 female patients who underwent type A aortic dissection surgery from February 2009 to October 2010 were collected. The mean age was 47 years. Postoperative acute respiratory dysfunction was defined as oxygenation impairment (PaO2/FiO2 < 150) that occurred within 72 h of surgery except pleural effusion, cardiogenic pulmonary edema, pneumonia, pulmonary embolism and haemato-/ pneumothorax. There were 187 acute A type aortic dissection patients and 65 chronic type A aortic dissection patients. Clinical characteristics including age, gender, weight, height, history of hypertension, history of smoking, preoperative complications such as preoperative shock and acute renal failure, pericardial effusion, previous cardiac surgery, time from event to surgery, malperfusion syndrome, cardiopulmonary time, cross-clamp time,deep hypothermia circulation arrest time, surgical procedure, duration of intensive care unit stay and postoperative complications including tracheotomy, dialysis dependent renal failure and hospital mortality were gathered. Arterial blood analysis, chest X ray, ventilator parameters, number of blood transfusion and flood balance were assayed after operation. All the factors were evaluated by means of univariate and multivariate logistic regression analysis to identify relative risk factors of ARD. Results Acute respiratory dysfunction occurred in 32 (12.7% ) patients. The in-hospital mortality was significant difference between acute respiratory dysfunction group and non- acute respiratory dysfunction group (P < 0.05). The value of BMI, incidence of acute aortic dissection, preoperative SBP level, cardio-pulmonary bypass time, aortic clamp time and total arch replacement in acute respiratory dysfunction group were significantly higher than the values in non- acute respiratory dysfunction group. Multivariate Logistic regression analysis showed blood transfusion more than 10 units and cardio-pulmonary bypass time more than 160 minutes were independent risk factors of early stage acute respiratory dysfunction after type A aortic dissection surgery.Conclusion Acute respiratory dysfunction after type A aortic dissection was a severe early stage postoperative complication and was associated with in-hospital mortality. The patients in acute aortic dissection were prone to have acute respiratory dysfunction. The independent risk factors of acute respiratory dysfunction included blood transfusion more than 10 units and cardio-pulmonary bypass time more than 160 minutes.

OBJECTIVE To investigate the protective effect of velvet antler polypeptides(VAP)on hydrogen peroxide( H2 O2 )-induced injury in vascular endothelial cells and the possible mechanism.METHODS The EVC-304 cells cultured invitrowere incubated with H2 O2 for another 12 h after pretreat-ment with VAP 20,40 and 80 mg·L-1 for 24 h. Cell viability was determined by MTT assay, Hoechst333258 staining was used to observe cell morphology,the activity of superoxide dismutase (SOD)and the level of malondialdehyde( MDA)were detected with kits and the expression of heat shock protein(HSP70)and caspase 3 was detected by Western blotting. RESULTS Compared with the normal control group,the cell survival rate was decreased significantly in H2 O2 injury group( P ﹤0.01),cell shrinkage,chromatin condensation,and nuclear fragmentation were seen,the intracellular SOD activity decreased while MDA content increased(P﹤0.01),and caspase 3 and HSP70 expression increased(P﹤0.01). Compared with H2 O2 group,the cell survival rate in VAP 20,40 and 80 mg·L-1 pre-treatment groups increased significantly(P﹤0.01),the apoptosis ratio declined from(25.3±1.0)% to (15.2±1.2)%,(10.3±0.9)% and(7.9±1.4)%(P﹤0.01),the SOD activity increased to 19.2±0.5,22.3± 1.7 and(24.9±0.6)kU·g-1 protein(P﹤0.01),MDA concentration decreased to 1.51±0.2,1.48±0.3 and (1.02±0.1)μmol·g-1 protein(P﹤0.01),and the expression of caspase 3 and HSP70 declined significant-ly(P﹤0.01). CONCLUSION VAP has exert protective effect on H2 O2-induced injury in vascular endothe-lial cells. The possible mechanism might be related to improvement of intracellular oxidative stress level.

Aim To investigate the mechanism of protection of reperfused ischemic heart by Gross Saponin Tribulus Terrestris(GSTT).Methods Hearts of 40 SD rats were isolated,linked to Langendorff perfusion apparatus,and randomly divided into 5 equal groups:control group,to be perfused with modified Kreb-Henseleit(K-H) buffer for 170 min;ischemia /reperfusion(I/R) group,to be perfused with K-H buffer for 20 min,exposed to ischemia for 30 min,and then reperfused with K-H buffer for 120 min;Chelerythrine group,to be perfused with K-H buffer with Chelerythrine,a PKC? antagonist for 20 min,exposed to ischemia for 30 min,and then reperfused with K-H buffer with Chelerythrine for 120 min;GSTT group,perfused with K-H buffer with GSTT for 20 min,exposed to ischemia for 30 min,and then reperfused with K-H buffer with GSTT for 120 min;and GSTT+Chelerythrine group,perfused with K-H buffer with GSTT+Chelerythrine for 20 min,exposed to ischemia for 30 min,and then reperfused with K-H buffer with GSTT+Chelerythrine for 120 min.The heart rate,mean aortic pressure and CK-MB were measured 20 min after the stabilization of perfusion,and 60 or 120 min after reperfusion.After the stop of reperfusion,hearts were sliced into 1-mm-thick transverse sections and incubated in triphenyltetrazolium chloride solution(TTC) to determine infarct size.The phosphorylation level and translocation of PKC? from hearts were determined by western blot analysis.Results GSTT significantly reduced infarct size from 63.2%?4.7% in controls to 37.2%?15.7%.And GSTT could reinforce PKC? translocate from cytoplasm to cellular membrane.Chelerythrine abolished these effects.Conclusion GSTT protects the heart from I/R injury partially by activating PKC?.
