4.Expression and significance of Maspin, vascular endothelial growth factor in endometrioid adenocarcinoma
Chinese Journal of Postgraduates of Medicine 2010;33(24):3-5
ObjectiveTo analyze the expression and clinical significance of Maspin, vascular endothelial growth factor (VEGF) in endometrioid adenocarcinoma tissue samples. MethodsForty-nine cases of endometrioid adenocarcinoma, 12 cases of atypical hyperplasia of endometrium and 15 cases of normal endometrium were selected. Immunohistochemistry was used to study the expression of Maspin,as well as VEGF. ResultsThe expression of Maspin was none in normal endometrium,while the positive rates of Maspin in atypical hyperplasia of endometrium (41.7%, 5/12 ) and endometrioid adenocarcinoma (59.2%,29/49) were ascending, there was statistical significance among the three groups (P<0.01 ). The positive rates of VEGF in normal endometrium ( 13.3%, 2/15 ), atypical hyperplasia of endometrium ( 33.3%, 4/12 ),endometrioid adenocarcinoma (67.3% ,33/49) also were ascending (P< 0.01 ). The expression of Maspin was related with the FIGO stage in endometrioid adenocarcinoma (P=0.034), and the expression of VEGF was related with the myometrial invasion(P = 0.036). There was positve correlation between the expression of Maspin and VEGF (r = 0.307,P<0.05). ConclusionsThe expression of Maspin, VEGF in tumor tissue has a significant correlation with the level of invasion of endometrioid adenocarcinoma. The expressions of Maspin,VEGF apparently play an essential role in the development and invasion of endometrioid adenocarcinoma.
5.Feature subset selection based on mahalanobis distance: a statistical rough set method
Journal of Pharmaceutical Analysis 2008;20(1):14-18
In order to select effective feature subsets for pattern classification, a novel statistics rough set method is presented based on generalized attribute reduction. Unlike classical reduction approaches, the objects in universe of discourse are signs of training sample sets and values of attributes are taken as statistical parameters. The binary relation and discernibility matrix for the reduction are induced by distance function. Furthermore, based on the monotony of the distance function defined by Mahalanobis distance, the effective feature subsets are obtained as generalized attribute reducts. Experiment result shows that the classification performance can be improved by using the selected feature subsets.
6.Contrast of efficacy between floxuridine and 5-fluorouracil for gestational trophoblastic tumor
Cancer Research and Clinic 2013;25(8):550-551,554
Objective To compare the efficacy and adverse reactions between floxuridine (FUDR) and 5-fluorouracil (5-Fu) treatment of gestational trophoblastic tumor.Methods 111 trophoblastic tumor patients of Ⅱ-Ⅲ stage including 62 cases of in vasive mole and 49 cases of choriocarcinoma were analyzed retrospectinely.The patients were divided into FUDR+KSM group (55 cases) and 5-Fu+KSM group (56 cases).FUDR was according to 23 mg/kg·d phleb instillation,keeping 8 hours,KSM was according to 6 μg/kg·d phleb instillation,keeping 4 hours.5-Fu was according to 26 mg/kg·d phleb instillation,keeping 8 hours.KSM was according to 6 μg/kg·d phleb instillation,keeping 4 hours.Both the two programs were 8 days.Results The cure rate was 98 % (54/55) in FUDR+DSM group,and that was 96 % (54/56) in 5-Fu+KSM group.The incidence rates of phlebophlogosis,dental ulcer and alopecie in the FUDR+KSM group were obviously lower than those in 5-Fu+KSM group [29.1% (16/55) vs 85.7 % (48/56),54.5 % (30/55) vs 98.2 %(55/56),21.8 % (12/55) vs 89.3 % (50/56),all P < 0.05].Both the FUDR+KSM group and the 5-Fu+KSM group bad significant differences at phlebophlogosis dental ulcer and alopecie in Ⅲ stages.Conclusion The curative effect of the FUDR is aimilar with the 5-Fu,but the drug consumption of the FUDR is less.The incidence rates of dental ulcer,alopecie,and phlebophlogosis are less,but myelosuppression and alvi profluvium are rcscmble between the two sets.
7.Effect of the Modified Baoyuan Tang on Macrophage Phagocytosid in Restrained Stress Mice
Chinese Mental Health Journal 1988;0(06):-
Objective: To investigate the effect of the modified Baoyuan Tang (BYT) with different doses on macrophage phagocytosis in restrained stress mice Method: 80 mice were randomly divided into 4 groups receiving different dose of BYT (stress only, 5g/kg, 10g/kg, 15g/kg) Using the intracellular phagocytosis in vivo to assess the phagocytosis ratio (Ph R) and phagocytosis index (Ph I) Result: The Ph R was highest in 10g/kg group The average of Ph I was also highest in 10g/kg group, but the difference between 10g/kg group and 5g/kg group had no statistic significance Conclusion:BTY 10g/kg has the best protective effect for decreased phagocytosis caused by restrained stress in mice
8.Negative Regulation of Toll-like Receptors Signaling Pathways
Progress in Biochemistry and Biophysics 2006;0(12):-
Toll-like receptors (TLRs) are key mediators of both innate and adaptive immunity by recognizing and eliciting responses to invading pathogens. The activation of TLRs must be stringently controlled in order to avoid exaggerated expression of signaling components as well as pro-inflammatory cytokines that can devastate the host,resulting in chronic inflammatory diseases,autoimmune disorders and aid in the pathogenesis of TLR-associated diseases. Therefore,it is essential that negative regulators act at multiple levels within TLR signaling cascades in order to synchronize the activation and negative regulation of signal transduction to limit potentially harmful immunological consequences. A summary of the various mechanisms employed by negative regulators of TLRs signaling to ensure the appropriate modulation of both immune and inflammatory responses was provided.
9.Correlation analysis on RA-based measurement of BMD and DEXA
China Medical Equipment 2014;(7):52-53,54
Objective: To investigate the correlation between BMD based on DR and DEXA. Methods: A total of 30 cadaver hand specimens were measured by bone mineral density measurement software based on RA developed by us and Hologic QDR-2000. Results: The overall results of F test were significant so that the data were analyzed by SPSS16 statistical software(r=0.7798, P<0.05). It is moderately and highly correlated between RA and DEXA. Conclusion: Self-developed software has a bright future because it is accurate and cheaper compared to foreign software.
10.Dynamic Determination of Active Ingredients in Introduced Echinacea purpurea
World Science and Technology-Modernization of Traditional Chinese Medicine 2014;(8):1858-1861
This study was aimed to analyze the dynamic accumulation of active ingredients of Echinacea purpurea. Contents of cichoric acid and total polyphenols in different parts through the whole growth process were determined by HPLC and colorimetry. The results showed that the content of total polyphenol changed little in annual plant. There were differences in content of cichoric acid of different parts in different periods. And the content reached the maximum at flowering stage. It was concluded that the harvest stage depended on the content of cichoric acid. The results provided theoretical basis for induced plant in Shandong province.
