Objective To determine the relationship between chronic colonic schistosomiasis and colorectal carcinoma.Methods Expression levels of c-erbB-2 and DPC4 were detected by two-step and SP immunohistochemical method respectively in normal colonic mucosa of 15 cases,in colonic mucosa of 15 cases with simple schistosomiasis,20 cases of colorectal carcinoma with schistosomiasis and 20 cases of colorectal carcinoma without schistosomiasis.Results c-erbB-2 was expressed in each group with different levels,but the level in colonic mucosa with schistosomiasis was the highest compared to other groups,which had statistical significance(P

Objective To investigate the technical charactenstics ot SYSMEX XS1000i 5-part differential automated hematological analyzer and its clinical applications.Methods 209 samples were analyzed with the analyzer of XS1000i and compared to the results from Beckman-Coulter LH750 analyzer.The main parameters from XS1000i,such as precision within-run,day to day precision and carryover contamination rates etc,were recorded respectively in 509 samples to compare the difference between the instrumental and optical examination.Results All variation coefficients of precision from XSI000i were within the manufacturer.The carryover contamination rates of WBC,RBC,Hb,HCT and PLT were 0.19%,0.93%,0,-0.88%,-0.76%,respectively.The parameters of XS1000i were correlated with the results of LH750 except basophil granulocyte.The correlation coefficients of WBC,RBC, HGB and PLT were 0.994 5,0.996 8,0.997 0 and 0.974 6 ,respectively.The sensitivity of warning flags in immature leukocytes was 100% and the specificity was 69.7%,the sensitivity of warning flags in atypical lymphocyte was 100% and the specificity was 66.7%.Especially in 3 leukocytopenia that was induced by chemotherapy in patients with leukemia who had only few immature cells existed in the peripheral blood,the parameters of XS1000i were positive,and correlated with the results of detection of minimal residual disease with flow cytometry.Conclusions The warning system of XSIO00i provides more valuable information for manual microscopic examination.If it is combined with flow cytometry,the advantages in detection of residual leukemic cell will be fully displayed.

Voltage-gated sodium channels (VGSCs) are known to be involved in the initiation and progression of many malignancies, and the different subtypes of VGSCs play important roles in the metastasis cascade of many tumors. This study investigated the functional expression of Nav1.5 and its effect on invasion behavior of human breast cancer cell line MDA-MB-231. The mRNA and protein expression of Nav1.5 was detected by real time PCR, Western Blot and immunofluorescence. The effects of Nav1.5 on cell proliferation, migration and invasion were respectively assessed by MTT and Transwell. The effects of Nav1.5 on the secretion of matrix metalloproteases (MMPs) by MDA-MB-231 were analyzed by RT-PCR. The over-expressed Nav1.5 was present on the membrane of MDA-MB-231 cells. The invasion ability in vitro and the MMP-9 mRNA expression were respectively decreased to (47.82+/-0.53)% and (43.97+/-0.64)% (P<0.05) respectively in MDA-MB-231 cells treated with VGSCs specific inhibitor tetrodotoxin (TTX) by blocking Nav1.5 activity. It was concluded that Nav1.5 functional expression potentiated the invasive behavior of human breast cancer cell line MDA-MB-231 by increasing the secretion of MMP-9.

AIM: To study the dissolution of ginsenoside Rb1,cinnamic acid and borneol in traditional Chinese medicine Shexiang Baoxin Pill(Moschus,extract of Radix et Rhizoma ginseng,Calculus Bovis artifactus,Cortex Cinnamomi,Styrax,Venenum Bufonis and Borneolum syntheticum). METHODS: The in vitro dissolution of active components in Shexiang Baoxin Pill was performed with paddle method. HPLC was used for determination of ginsenoside Rb1 and cinnamic acid,and GC for borneol. RESULTS: The analytic method above was easy to carry out,the requirement of the specificity,accuracy,precision and stability could meet the needs of experiment well; the dissolution time T50 and Td of ginsenoside Rb1,cinnamic acid and borneol were 30. 90,33. 79 min,29. 73, 37. 11 min and 42. 38,48. 51 min respectively. CONCLUSION: The dissolution rate of three active components from Shexiang Baoxin Pills was fast and the analytic methods established in this study could be used to evaluate the quality of the preparation.
