Conclusion: To improve the level of human health, it needs to take comprehensive measures.

Second primary malignancies are more likely to occur in the multiple myeloma patients .Most of them are Acute myeloid leukemia ( AML) or Myelodysplastic syndrome ( MDS) .The incidence in male or those multiple myeloma patients who is less than 60 years old are more than female or those multiple myeloma patients who are bigger than 60 years old.In recent years,studies of multiple myeloma secondary to leukemia and other tumors are gradually increasing ,but the mechanism and treatment are still unclear .These diseases have the follow-ing characteristics such as progress rapidly ,high mortality rate and low complete remission rate after chemothera-py.

Objective To investigate the effect of early life stress on the locomotion and concentration of corticosterone in peripheral blood in adult rats.Methods Maternal deprivation and isolation were used in the model of early life stress. Chronic stress was used in adult rats.Open field test was used for the measurement of locomotion activity. ELISA was used to measure the concentration of corticosterone in peripheral blood.Results The total activity time of locomotion[(296.96±6.63)s, (291.06±8.40)s;P＜0.01] and the concentration of corticosterone [(15.51±2.41)nmol/L,(11.27±2.49)nmol/L;P＜0.05]were increased in adult rats by maternal deprivation. The total activity distance [(23231.29±2030.35)mm,(14042.81.06±2875.34)mm;P＜0.05] and time[(296.39±3.48)s,(259.18±4.71)s;P＜0.01]were increased after chronic stress which was used in adult rats in which maternal deprivation were used before. The concentration of corticosterone[(20.60±1.83)nmol/L,(14.49±1.37)nmol/L;P＜0.01]was also increased in the same condition.Conclusions The concentration of corticosterone and locomotion activity of adult rats can be increased by early life stress. The reaction of HPA axis for chronic stress was improved by early life stress.

Objective To assess the clinical value of transcatheter arterial chemoembolization(TACE) for the treatment of metastatic liver leiomyosarcoma(MLL).Methods CT triphasic scanning and TACE were performed in 8 patients with MLL,which was proved by fine-needle aspiration biopsy and immunohistochemical study.A follow-up of 1-3 years was conducted.Based on the enhancement degree of the hepatic lesion and the DSA manifestations of the lesion,which were observed both before and after TACE,and also on the survival time,the therapeutic effectiveness was evaluated.Results Of the eight cases,single metastasis was seen in 3 and multiple metastasis in 5.Excellent result was obtained in 6 cases and good result in 2 cases.Based on the imaging findings,marked effect was seen in 3 cases,good effect in 4 cases and no improvement in one case.The surviva1 rate at 1,2 and 3 years was 87.8%,50.0% and 37.8% respectively.Conclusion TACE is a safe and effective treatment for MLL.

Objective To investigate the relationship between matrix metalloproteinase-9 (MMP-9) gene-1562 C/T polymorphism and hemorrhagic transformation (HT) from (IS) in Chinese Han population in Henan province.Methods The promoter-1562 C/T gene polymorphism in 84 IS patients with HT and 138 age-and sex-matched IS patients without HT were tested by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP).The genotypes and alleles frequencies of-1562 C/T polymorphism were analyzed.Results The frequency of CT and TT genotype and T allele was lower in IS patients with HT than in IS patients without HT (17.86％ (15cases) vs.30.43％ (42 cases),8.93％ (15 cases) vs.15.94％ (44 cases),x2=4.326 and 4.458,P=0.037 and 0.035).The relative risk for HT from IS was decreased in patients with T allele than those withCTandTTgenotype[0.517 (95％CI:0.278-0.961) vs.0.497 (95％CI:0.255-0.967)].Conclusions The MMP-9 gene-1562C/T polymorphism may be related to hemorrhagic transformation of in Chinese Han population in Henan province.The T allele is a protective factor for hemorrhagic transformation of in the population.

Objective To evaluate the expression of Yes-associated protein (YAP) in colorectal carcinoma and analyze its influence on tumor cell proliferation.Methods The expressions of YAP in 94paired colorectal carcinomas and pericancerous normal tissues were detected by using immunohistochemistry method.The expressions of YAP in colorectal carcinoma cell line HCT116 were inhibited with a YAP-spe-cific siRNA.Cell proliferation was then determined by methyl thiazolyl diphenyl-tetrazolium bromide (MTT) assay.Results The positive rate of YAP in colorectal carcinomas was significantly higher than that in pericancerous normal tissues [69.1％ (65/94) vs 22.3 ％ (21/94),P ＜ 0.001].The expression of YAP was associated with tumor Node Metastasis(TNM) stage and lymph node metastasis(P ＜0.05),but not associated with gender,age,tumor location and histological grade(P ＞0.05).After YAP-specific siR-NA was transfected into HCT116 using lipofectamine,the expression of YAP mRNA and protein in the experimental group were reduced by (78.2 ±2.1)％ and (81.7 ± 1.5)％,respectively,with a statistically significant difference (t =67.55,91.601,P ＜0.01).The growth of HCT116 was significantly inhibited and the reduced rate of cell proliferation was (28.1 ± 1.6) ％,(34.7 ± 2.4) ％ and (24.7 ± 1.2) ％ at the time point of 48 h,72 h and 96 h,respectively.Conclusions Expression of YAP was upregulated in colorectal carcinomas and downregulation of YAP expression could inhibit growth of colorectal carcinoma cells.YAP can be used as a new candidate target for diagnosis and treatment of a colorectal carcinoma.

Objective To study and compare the protective effects of pmtease inhibitor and corticosteroid on endotoxin-indueed acute lung injury in order to guide the choice of appropriate drugs. Method Thirty-two New Zealand rabbits were randomly divided(random number) into four groups with 8 rabbits in each, namely normal controls(C) ; lipopolysaecharide(LPS) group(L) ; ulinastatin(UTI) group(U) and dexamcthasone(DEX) group (D) .Except group C, all rabbits were injected with a dose of LPS 600 μg/kg iv. Meanwhile the rabbits in group U,group D received UTI(100 000 μ/kg), DEX(5 mg/kg), respectively. The specimens were collected 4 hours later for detecting the levels of TNF-α and NO in serum, and blood gas analysis, histological manifestations, the lung wet/dry weight ratio, lung tissue MPO and SOD activity, lung tissue MDA. Data were analyzed by ANOVA (SNK- q test), and P < 0.05 was considered as significantly different. Results Compared with group C, the lungs of the rabbits in group L had inflammatory granulocyte infdtration, diffused alveolar septum thickening and hemorrhagic spots were observed in pathological examinations. The histological changes of group U and group D were much lessened than those in group L. As groups U and D were compared with group L, there were significant differences inmany biomarkers including lung wet/dry weight ratio[(5.02±0.11),(4.93±0.13) vs.(5.37 ±0.29)],lung tissue MPO activity[(0.51 ± 0.05),(0.54±0.07) vs.(0.82 ± 0.09)] and MDA[(0.82 ±0.05),(0.81 ±0.04) vs.(0.96±0.05)], NO[(296.2± 11.7),(291.7 ± 15.8) vs.(351.8±19.6)] and TNF-α[group D(2.021 ± 0.122) vs. group L(4.999 ± 0.139)],lung tissue SOD activity[(120.3 ± 6.1),(122.6±3.5) vs.(105.1 ± 8.5)] and blood gas analysis[pH(7.30±0.23),(7.30±0.17) vs.(7.22±0.45) and PaO_2( 101.9 ± 6.8).( 102.5 ± 4.7) vs.(80.3 ± 3.3)] ; but there were no differences of above mentioned biomarkers between group U and D( P > 0.05). And there were no significant differences in PaCO_2 betweeu group U and D and group L[(37.0 ± 3.3),(37.6 ± 3.0) vs.(34.8 ± 2.3)]( P > 0.05). Conclusions The protective effects of ulinastatin on endotoxin-induced acute lung injury is comparable to those of dexamethasone, thus the former may be a clinical substitute for the latter with less side effects.

A novel polymer- overoxidized polypyrrole film chemically modified electrode (CME) as the liquid chromatography-electrochemical detector (LC-ECD) was fabricated and applicated, which could be used to determine the monoamine neurotransmitters. The experimental model of parkinsonian animal was established by using medicine. Microdialysis sampling coupled with LC-ECD was used to monitor the monoamine neurotransmitters and their metabolites in experimental animal brain in vivo under different situations. The mechanism of experimental animal's Parkinsonian disease was studied elementarily. An accurate and reliable analysis method was supplied for filting the new and the more effective medicine to cure parkinsonian disease.
