Objective To investigate the expression of inhibitors of apoptosis (IAPs) in non-small cell lung cancer (NSCLC) patients and its clinical significance. Methods The mRNA expression level and protein level of survivin, hIAP-1 (human IAP-1), hIAP-2 (human IAP-2), and XIAP (X chromosome-linked IAP) in 36 NSCLC patients and 36 controls were analyzed by semi-quantitative reverse transcription polymerase chain reaction (RT-PCR) and Western blotting, respectively. Results High survivin mRNA expression were detected in 32 out of 36 patients, but not in controls. 26/36 NSCLC showed high XIAP mRNA expression and were significantly higher than those with benign diseases (P

Objective To investigate the preventive effects of aspirin on liver metastases of colorectal cancer in mice and study the mechanisms.Methods Twenty BALB/c mice were divided into the control group and the experimental group according to the random number table with 10 mice in each group.Mice in the control group were fed with saline each day at a concentration of 0.2 mL/d for 60 days,while mice in the aspirin group were fed with aspirin each day at a concentration of 30 μg/(g · d) for 60 days.Then C26 colon cancer cells were injected into the spleen and then the spleen was cut to establish mice model of colon cancer liver metastasis.The C26 colon cancer cells were divided into 2 groups.C26 colon cancer cells in the control group remained untreated,and C26 colon cancer cells in the experimental group were treated with aspirin at a concentration of 10 mmol/L for 24 hours.The scratches and transwell assays were conducted to observe the effects of aspirin on the invasion and metastasis of C26 colon cancer cells.The expressions of epithelial-mesenchymal transition (EMT)-related genes were detected using RT-PCR and Western blot.All data were analyzed using the Student t test.The survival curve was drawn by Kaplan-Meier method,and the survival analysis was done by Log-rank test.Results The numbers and weights of hepatic metastatic tumors were 4.8 ± 1.9 and (504 ± 107) mg in the control group and 2.6 ± 1.6 and (362 ± 67) mg in the experimental group,with significant difference between the 2 groups (t =2.840,3.584,P ＜ 0.05).The 1-month survival rate was 80％ in the experimental group,which was significantly higher than 40％ of the control group (x2=4.418,P ＜ 0.05).The results of pathological examination showed that tumor cell heteromorphism was reduced by aspirin.The results of scratches experiment showed an obvious migration of C26 colon cancer cells in the control group at 24 hours later,while no C26 colon cancer cells migrated in the experimental group.The numbers of C26 colon cancer cells penetrated the Watrige were 253 ± 21 in the control group and 148 ± 13 in the experimental group,with significant difference between the 2 groups (t =5.101,P ＜0.05).The relative mRNA expression of the E-cadherin and the Vimentin were 0.002 ±0.001 and 1.005 ±0.286 in the control group and 0.005 ± 0.001 and 0.270 ± 0.168 in the experimental group,with significant difference between the 2 groups (t =-4.606,4.942,P ＜ 0.05).The relative protein expressions of the E-cadherin and the Vimentin were 0.473 ±0.179 and 0.787 ± 0.118 in the control group and 1.585 ± 0.410 and 0.280 ± 0.133 in the experimental group,with significant difference between the 2 groups (t =-5.542,6.355,P ＜ 0.05).Conclusion Aspirin inhibits liver metastasis of colon cancer and promote the survival ratio of mice.Aspirin can up-regulate the expression of E-cadherin and down-regulate the expression of Vimentin,which inhibits EMT and reduces the invasion and metastasis of tumor cells.

Objective To study the feature of clinical and pathological type of Henoch-Sch(o)nlein purpura nephritis (HSPN) in children.Methods Clinical and pathological data of HSPN in 279 children were collected and retrospectively analyzed.Results Clinical manifestation of HSPN in 279 children with haematuria and proteinuria (107 cases,38.4％) was the most common type,followed by nephritic syndrome type (69 cases,24.7％),isolated proteinuria type (40 cases,14.3％),isolated hematuria type (29 cases,10.4 ％),acute glomerulonephritis type (21 cases,9.3 ％),rapidly progressive glomerulonephritis type (8 cases,2.9％),chronic glomerulonephritis type (5 cases,1.8％).According to the International Study of Kidney Disease in Children,the majority renal pathological type of HSPN were grade Ⅱ (133 cases,47.7％)and grade Ⅲ (109 cases,39.1％).The pathological changes of hematuria and proteinuria type were mainly grade Ⅱ (61 cases,57.0％) and grade Ⅲ (35 cases,32.7％),and the pathological change of nephritic syndrome type was grade Ⅲ (41 cases,59.4％).All of renal pathological changes,38.7％ (108/279) had codeposition of immunoglobulins A and M,30.8％ (86/279) had co-deposition of immunoglobulins A,G and M.The pathological change of nephritic syndrome type was more serious (x2 =35.989,P ＜ 0.05).Immune complex deposition was not correlated with renal pathologic classification (P ＞ 0.05).Conclusion The HSPN patients mainly show the type of hematuria and proteinuria and the type of nephritic syndrome.The majority renal pathological type of HSPN are grade Ⅱ and grade Ⅲ.In children with HSPN,the severity of the clinic symptoms is not completely consistent with the pathological changes.The pathological changes of nephritic syndrome type are more serious.To improve theprognosis of HSPN,we should make the treatment planning according to the clinical types and pathologic classification.

Models of throat excess-heat mice were established and different dosages of water extract of STRR were ig given to mice to observe anti-inflammatory effect and its mechanism. The activities of ALT, AST and the contents of TNF-α, T3, rT3, T4, SOD, MDA, PEG2, NO, NOS, Cr, BUN, GSH and GSH-Px in serum were tested while liver index, kidney index, spleen index and thymus index were measured. The anti-inflammatory efficacy accompanied by side effects and mechanisms of water extract of Sophorae Tonkinensis Radix et Rhizoma (STRR) in excess-heat mice were investigated to clear safety dose-dependence range and the relationship of efficacy, toxicity and syndrome. In the experiment, water extract of STRR showed a strong inhibitory effect on ear edema by croton oil in throat excess-heat mice. The activities of ALT, AST in serum and liver index were all higher than that of normal group after multiple administration. PEG2, SOD, MDA, NO, NOS, GSH and GSH-Px had obvious changes. According to the results, water extract of STRR has an anti-inflammatory effect on acute inflammation in throat excess-heat mice and it is stronger than that in normal mice. The anti-inflammatory effect of STRR is related to the reduction of inflammatory mediators release. Side effects and hepatotoxicity will be produced on clinical efficacy dosage. The mechanisms of anti-inflammation and hepatotoxicity are all in connection with oxidative damnification.

Salvianolic acid A (Sal A) is one of the most effective compounds isolated from the root of Salvia miltiorrhiza. Up to now, several studies regarding the pharmacokinetic profiles of Sal A have been reported, however there is no such study reported in monkeys, the species which is more similar to human. The aim of this study is to develop a LC-MS method for the determination of Sal A in monkey plasma and apply it to the pharmacokinetic studies of monkeys. After single intravenous administration of Sal A, the plasma concentration-time curves were observed and the main pharmacokinetic parameters were calculated. The plasma concentration at 2 min (C2 (min)) values were (28.343 ± 6.426), (45.679 ± 12.301) and (113.293 ± 24.360) mg x L(-1) for Rhesus monkeys treated with Sal A at 2.5, 5 and 10 mg x kg(-1). The area under the concentration-time curve (AUC(0-∞)) values were (3.316 ± 0.871), (5.754 ± 2.150) and (13.761 ± 2.825) μg x L(-1) x h, respectively. Furthermore, this method was improved and applied to the simultaneous determination of Sal A, Sal B and Sal C, which provided useful information for preclinical studies and clinical trials of Sal A, Sal B and Sal C.
