Objective: To investigate the expression of HSP-27,-60 and -90 in gastric cancer and its clinical significance. Methods:66 cases of gastric carcinoma was detected by immunohistochemistry HSP-27,60 and 90 of the expression and clinical significance of combined with clinical and pathological characteristics, tumor cell proliferation and survival analysis of three kinds of heat shock protein expression. Results: HSP-27,-60 and -90 were highly expressed in gastric cancer tissues. HSP-27 expression and tumor size (pT,P=0. 026),organ metastasis (pM,P=0. 046) and pathological staging (P=0. 041),HSP-27 staining intensity and lymph node status were significantly correlated ( pN, P=0. 042 ) . HSP-60 expression was associated with gender ( P=0. 011),and HSP-60 staining intensity was associated with age (P=0. 027) and tumor grade (P=0. 031). There was no correlation between HSP-90 expression and the clinical pathological parameters of this study; however, the intensity of HSP-90 staining was significantly correlated with tumor size (P=0. 020,pT). Single factor analysis showed that HSP-90 was significantly associated with longer survival (P=0. 033). Multivariate analysis demonstrated that HSP-90 was highly expressed as an independent prognostic factor for gastric cancer (P=0. 026). Conclusion: the HSP-27,-60 and -90 and some clinical pathological parameters. These parameters is very important for the treatment of patients with gastric cancer. The high expression of HSP-90 in patients with gastric cancer were inde-pendent prognostic indicators.

OBJECTIVETo investigate the effect of Xianxiong decoction on the mice with acute lung injury induced by lipopolysaccharide.

METHODEighty female ICR mice were randomly divided into 8 groups: model group, Xianxiong decoction group, Daxianxiong decoction group, Xianxiong decoction group without Kansui Radix group, Xianxiong decoction group without Glycyrrhizae Radix et Rhizoma group, Glycyrrhizae Radix et Rhizoma and Kansui Radix group, normal group and control group. Animals of each group, except normal group, were undertaken intraperitoneal injection and intranasal inhalation of lipopolysaccharide (LPS) on day 1, 2, 3 to establish acute lung injury (ALI) model. 30 min after modeling, 0.2 mL corresponding drugs were administrated to each mice, dexam ethasone and normal saline were given to the mice of control group and normal group respectively. White blood cell in blood, neutrophil percentage of blood and bronchoalveolar lavage fluid (BALF) supernatant, the ratio of wet and dry lung tissue ( W/D), histopathological changes of lung tissue were estimated. Sixty ICR mice were randomly divided into normal, model, control, high, middle and low dose Xianxiong decoction groups and were modeled in the same way. ELISA was applied to detect the level of NF-kappaB, TNF-alpha and IL-6 in BALF, PCR for NF-kappaB and TNF-alpha mRNA in lung tissue, and Western blot for NF-kappaB and TNF-alpha. Half of 20 ICR mice were administrated with Xianxiong decoction of its maximum tolerant normal saline.

RESULTCompared with model group, the number of WBC in blood of Xianxiong decoction group mice decreased (P < 0.01), percentage of neutrophils in both blood and BALF decreased as well (P < 0.01, P < 0.05); it also significantly reduced the ratio of W/D (P < 0.01); and found the alveolar wall, the number of inflammatory cells infiltrating improved, compared with model group. Xianxiong decoction reduced the level of NF-kappaB, TNF-alpha and IL-6 in BALF (P < 0.01, P < 0.01, P < 0.05); its high and low dose groups only found TNF-alpha level declined. Five mice died 24 h after administration of Xianxiong decoction which indicated its toxicity when other influential factors were considered.

CONCLUSIONXianxiong decoction is effective on the ALI mice induced by LPS, but it is of toxicity at 3 g x mL(-1).
