Objective To investigate the role of survivin and P53 in apoptosis of gastric adeno- carcinoma,as well as its relationship with the clinicopathologic features and the prognosis.Methods The gas- tric tissue microarrays were composed of those from 100 cases of gastric cancer and 30 controls.At these tissue microarrays,expressions of survivin and P53 were investigated immunohistochemically,and tumor cell apoptosis index was examined by TUNEL method.Of the 100 cases,47 cases were followed-up from 14 months to 13 years,in which the survival was analyzed.Results Two paraffin-embedded gastric carcinoma tissue micro- arrays were successfully constructed,including 114 and 116 tissue spots,respectively.Immunohistochemical analysis showed that survivin was expressed in 78 cases (78%).No expression of survivin was detected in control tissue (P0.05).In the 47 cases with followed-up data,univariant analysis revealed that the survival was correlated with invading of vessel and nerve,TNM stages,and expression of survivin.The histological grades and expression of P53 were not related to prognosis.However,Cox stepwise proportional hazards analysis showed that only TNM staging and survivin status retained significant independently in prospecting prognosis.Conclusions The expression of survivin was associated with the pathologic features,TNM stages and prognosis in gastric carcinoma,indicating that overex- pression of survivin may be a poor prognosis factor for gastric carcinoma.

Objective To identify the interaction between nuclear localization signal-retinoic acid receptor α (NLS-RARα) and Ubiquilin 1(UBQLN1). Methods The recombination expression plasmids pGBKT7-NLS-RAR and pACT2-UBQLN1, which expressed bait-protein NLS-RARα and target protein UBQLN1 respectively, were cotransformated into yeast AH109. The interaction of the expression plasmids in the living cells was investigated by yeast two-hybrid assay. HA-tagged fusion protein (pCMV-HA-NLS-RARα) expression vector and Myc-tagged fusion protein (pCMV-Myc-JTV1) expression vector were constructed, identified, and cotransfected respectively into human embryo kidney 293 cells(HEK293). The interaction was detected by co-immunoprecipitation.Results Blue clones were found on yeast AH109 plate cotransformated with pGBKT7-NLS-RARα and pACT2-UBQLN1. Double restriction enzyme digestion showed that pCMV-HA-NLS-RARα and pCMV-Myc-JTV1 were successfully constructed. Then HA-NLS-RAR protein was immunoprecipitated by anti-HA polyclonal antibody and the expression of Myc-UBQLN1 was tested by Western blot with anti-Myc monoclonal antibody from immunoprecipitated complex. Conclusion The interaction between NLS-RARα and UBQLN1 can be verified by yeast two-hybrid assay and co-immunoprecipitation.

This study was aimed to verify the effects of staged sequential therapy on expressions of matrix metalloproteinase-9 (MMP-9) and its inhibitor TIMP-1 within lung tissues in asthmatic rats with the airway remodeling, by applying a series of tests such as the immunohistochemistry, western blot and real-time fluorescent quantitative PCR. SD rats were randomly divided into 7 groups, which were the asthmatic group (Group X), the normal group (Group Z), the No. 1 sequential therapy group (Group A1), the No. 2 sequential therapy group (Group A2), the No. 3 sequential therapy group (Group A3), the montelukast group (Group M), and the budesonide group (Group B). The asthmatic model was established in each group except Group Z, by sensitization with both ovalbumin (OVA) and aluminium hydroxide via injection at the 1st, 8th and 15th day in a 22-day duration, followed by OVA aerosol inhalation every other day for 8 weeks for asthma activation. At the 8th day after the asthmatic model was established, Group A1 was orally given Ma-Xing Er-Chen Tang (MXECT) during acute phase while given normal saline (NS) during catabasis and stable phase; Group A2 was given MXECT during acute phase, and given modified Jin-Shui Liu-Jun Jian (JSLJJ) during catabasis as well as given NS during stable phase; Group A3 was given MXECT during acute phase, and given modified JSLJJ during catabasis as well as given Liu-Wei Di-Huang (LWDH) Powders during stable phase;Group M was given salbutamol via aerosol inhalation after stimulation, while orally given montelukast during catabasis and stable phase; Group B was given salbutamol via aerosol inhalation after stimulation, while given inhaled budesonide during catabasis and stable phase; Group X was given NS. After the 7-week intervention, the immunohistochemistry, western blot and real-time quantitative PCR were applied to analyze the location and quantitative expression of MMP-9 and TIMP-1, so as to find out the biological mechanism on expressions of MMP-9 and TIMP-1 in lung tissues of asthmatic rats from molecular levels to gene levels. The results of immunohistochemistry, western blot and real-time fluorescent quantitative PCR showed as follows. Compared with Group Z, the contents of MMP-9 and TIMP-1 increased significantly within lung tissues in Group X. Compared with Group X, the contents of MMP-9 and TIMP-1 decreased within lung tissues of asthmatic rats in each treatment group. It was concluded that the expression of MMP-9 and TIMP-1 elevated during asthma. TCM staged sequential therapy can regulate the ratio between MMP-9 and its inhibitor so as to block the airway remodeling, by decreasing the expression of MMP-9 and its inhibitor within lung tissues in asthmatic rats. This is one of the important action mechanisms.
