Objective To investigate the expression and significance of IDO and c-myc in bladder urothelial carcinoma.Methods IDO mRNA expression from fresh tumor and mucosa specimens from 20 cases were detected by fluorescence quantitative PCR,and SP was used to detect the IDO,c-myc protein in paraffin-embeded specimens from 84 cases and mucosa specimens from 22 cases.Results In bladder urothelial carcinoma,IDO,c-myc protein expression level had no relationship with age and sex.Expression of IDO protein in invasive bladder urothelial carcinoma was significantly higher than that of no-invasive (x2 =5.600,P =0.018).With the increase of the histological grade (x2 =20.268,P =0.000) and UICC stage (x2 =12.075,P =0.007),the positive expression rate of IDO protein was increased.There was not positive expression of c-myc protein in normal bladder tissue,but in bladder urothelial carcinoma,44 cases (52.4 ％) were positive expression (x2 =10.733,P =0.001).The expression of c-myc protein had no relationship with the histological classification,histological grade and UICC stage.In bladder urothelial carcinoma tissue,IDO protein expression level was positively correlated with c-myc protein expression (r =0.205,P =0.047),and was positively correlated with the histological classification,histological grade and UICC stage (r =0.258,P =0.018; r =0.491,P =0.000; r =0.365,P =0.001).Expression of IDO mRNA in bladder urothelial carcinoma (7.696 1±1.745 2) was significantly higher than that in normal bladder tissue (6.397 0±1.205 1)(t =2.367,P =0.023).The average expression level of IDO mRNA in bladder urothelial carcinoma of Ta-T1 stage was 6.803 4±1.567 5,which was significantly lower than that in T2-T4 stage (9.183 8±0.690 3) (t =4.955,P =0.000).The average expression levels of IDO mRNA in grade Ⅰ,Ⅱ,Ⅲ bladder urothelial carcinoma were 7.058 7±1.771 5,7.934 2±1.530 5,9.290 7±0.574 5,respectively,which were increased with the grade increasing (t =2.729,P =0.011).Conclusions The high expression of IDO correlates with bladder urothelial carcinoma progression,and expression of c-myc is irrelevant with bladder urothelial carcinoma progression,but maybe associate with bladder urothelial carcinoma occurrence.IDO may be a predictive factor of prognosis.IDO and c-myc may be therapeutic target in the treatment of bladder urothelial cancer.

Objective To investigate the expression and significance of bin 1,C-myc in bladder urothelial carcinoma.Methods SP method was used to detect the expression of bin 1,C-myc protein in paraffin specimens from bladder urothelial carcinoma of 84 cases and mucosa of 11 cases,and its relationship with clinical pathological charac-teristics was analyzed.Results The positive expression rate of bin1 in normal bladder tissues was 81.81%,that in bladder urothelial carcinoma was 46.43%,the difference was not significant (χ2 =4.873,P=0.051).No expression of C-myc was observed in normal bladder tissue ,the positive expression rate of C-myc in bladder urothelial carcinoma was 52.38%,the difference was statistically significant (χ2 =10.733,P=0.001).The expression of bin1 in invasive bladder urothelial carcinoma was significantly lower than the non-infiltrating type(χ2 =7.685,P =0.007),with increased histological grade and UICC stage ,the positive rate of bin1 expression decreased (χ2 =15.817,P=0.000;χ2 =11.104,P=0.010).The expression of C-myc had no relationship with the histological classification ,histological grade and UICC stage .Correlation analysis showed that the expression of bin 1 was negatively correlated with histologi-cal classification,histological grade and UICC stage (r=-0.302,P=0.005;r=-0.411,P=0.000;r=-0.302, P=0.005).With the increased expression of bin1,C-myc expression decreased,but the difference was not statistical-ly significant.Conclusion Low expression of bin1 or loss of bin1expression were associated with the progression of bladder urothelial carcinoma , the expression of C-myc was related with bladder urothelial carcinoma lesions .The results suggest that bin1 may be predictive factor for prognosis of urinary bladder urothelial carcinomas ;bin1,C-myc may be viewed as molecular targets for tumor chemotherapy .

Objective To observe the effects ofXiaotan Sanjie Decoction on ultramicrostructure in MKN-45 human gastric cancer orthotopic xenograft;To discuss its mechanism for gastric cancer. Methods MKN-45 human gastric cancer cell line was used to establish subcutaneous tumor model in nude mice as an experimental model which passed three generations of tumor source. Then OB glue was used to establish human gastric cancer orthotopic xenograft model. 40 model nude mice were divided into control group, model group (received gavage with saline),Xiaotan Sanjie Decoction group (received garage withXiaotan Sanjie Decoction) and Tegafur group (received gavage with Tegafur), 10 mice in each group. Mice in the control group were under normal diet, without medicine intervention. After 6 weeks of treatment intervention, tumor weight was detected, inhibitory rate was calculated, the ultrastructural changes of gastric cancer cells were detected through transmission electron microscopy.Results The tumor weight inXiaotan Sanjie Decoction group was significantly lower than that in control group and model group (P<0.05,P<0.01). The tumor inhibition rate was 46.2%. Under the electron microscope, MKN-45 gastric cancer cells strain changed to typical apoptosis.ConclusionXiaotan Sanjie Decoction can lead to apoptosis effects on MKN-45 human gastric cancer orthotopic xenografts. All evidences indicate that inducing apoptosis may be one of the most important mechanisms ofXiaotan Sanjie Decoction in treating gastric cancer.

A total of 100 insomniacs were randomly divided into intervention and contrast groups (n=50 each).The contrast group took only alprazolam while the intervention group received both alprazolam and other comprehensive regimens,including acupuncture,psychotherapy and traditional Chinese medicine.One course of treatment lasted 10 days for both groups and 6 courses were offered.After comprehensive interventions,as compared with contrast group,the scores of Pittsburgh Sleep Quality Index (PSQI) and Athens Insomnia Scale (AIS) decreased obviously in intervention group (P ＜ 0.05).And the curative rate (46％) and the total efficacious rate (96％) of intervention group were higher than those of contrast group (P ＜ 0.05).
