Objective To explore the effect of Angiotensin Ⅱreceptor inhibitor on proliferation and apoptosis and cell cycle of human en-dometrial cancer cell line induced by estrogen.Methods Human endometrial cancer cells,ishikawa were cultured,and then treated with different concentrations of estrogen or saralasin.Cell proliferation was examined using MTT,and cell cycle and apoptosis were determined us-ing flow cytometry.Results Saralsin inhibited the proliferation of ishikawa cells.After treated with saralasin at 10 min after estrogen induc-tion,cycle was arrested at G1/G0 phase and S phase was reduced in ishikawa cell with significant difference between treatment group and control group.An increase in early apoptosis and late apoptosis occurred at 10min after treatment.Conclusion Saralsin inhibits endometrial cancer cell ishikawa proliferation,induces apoptosis and accumulation in G1/G0 phase in vitro.Therefore,saralsin may be helpful for the treat-ment of endometrial cancer.

AIM:To improve the standard of quality control of Yiqi Zhixue Granule(Radix Codonopsis,Radix Astragali,Rhizoma Atractylodis macrocephalae,etc.) METHODS: In the prescription,both Radix codonopsis and Radix Astragali were identified by HPLC.Folium mahoniae was distinguished by TLC.Rhizoma Bletillae was authenticated by microscope.Morever,RP-HPLC method was adopted to determine the astragaloside content in the productions,using a column of C_(18),the column temperature was at 35(?C),acetonitrile-water(32∶68) as a mobile phase,he flow rate was 1.0 mL/min,and ELSD as detection in which the tube temperature was set at 102(?C) and the air flow was at 2.8 mL/min,the impactor was chosen off. RESULTS: The established identification methods were simple and proper,reflecting a good specificity,while the determination method was accurate and reliable,which showed the recovery of 97.95%,RSD=2.21%(n=9),the intermediate precision of RSD=2.67%(n=3),the robustness of RSD=3.67%(n=3) between columns,and the LOQ of 0.539 2 ?g,RSD=2.92%(n=5). CONCLUSION: The improved standard of quality control of Yiqi Zhixue Granule is not only practical but capable of effectively controlling the quality of the medicine as well.

Objective To study the relationship between the expression of p16 protein and the biological behavour of thyroid tumor. Methods The expression of p16 protein was examined in fifty cases of thyroid tumor by immunohistochemical staining technique(SABC method). The relationship between p16 protein expression and tumor size, pathological type, differention grading and clinical stage of thyroid tumors were analysed. Results In thyroid adenoma, p16 protein expression was detected in 13 out of 15 cases(86.7%); in thyroid carcinoma p16 protein was expressed only in 16 out of 35 cases(45.7%), the difference was significant(P

Objective:Mobile X-ray radiographic Units to appear in the clinical application of high voltage circuit judge special case of failure, the analysis in order to provide effective and reliable service basis. Methods: Preliminary judgment based fault location fault code, using stepwise exclusion analyze, judge, and determine the cause of the failure lies. Results:The high-voltage inverter element models of mobile DR, the driver circuit, the output voltage discharge waveform judgment and other issues have a better understanding, to facilitate the exclusion of equipment failure. Conclusion:Special case of X-ray radiographic Units failure high voltage circuit analysis and troubleshooting, especially for the inverter circuit analysis, X-ray radiographic appear to take timely and appropriate repair method when high pressure overload.
