Objective: To study the influence of gallic acid (GA) on the migration of human gastric carcinoma SGC-7901 cells, and to explore its mechanism.Methods: The human gastric carcinoma SGC-7901 cells were cultured and divided into control group and 3.125, 6.250, 12.500, 25.000, 50.000,100.000 mg·L-1 GA groups. The inhibitory rates of proliferation of SGC-7901 cells in various groups were examined by MTT assay;the migration abilities of SGC-7901 cells in various groups were measured with scratch assay;the expression levels of vascular of endothelial growth factor (VEGF) in various groups were detected by immunocytochemistry.Results: Compared with control group, the inhibitory rates of proliferation of SGC-7901 cells in different doses of GA groups were significantly increased in a dose-dependent manner(F=59.451,P<0.01).Compared with control group, the wound healing rates in different doses of GA groups were significantly decreased (P<0.01).Compared with control group, the expression levels of VEGF protein in 12.500 and 25.000 mg· L-1 GA groups were decreased (P<0.05).Conclusion: GA could inhibit the proliferation and migration of SGC-7901 cells through down-regulating the expression levels of VEGF protein.

Object To study the effects of artemisinin and its analogue artemisunate on the proliferation of human breast cancer MCF-7 cell line, as well as their mechanism comparatively. Methods The inhibition of cell proliferation was determined by SRB method. Cell cycle was determined by flow cytometry (FCM) analysis. Apoptosis was confirmed by sub-G 1 cells content and DAPI method. Results The cell cycle of MCF-7 was changed greatly when treated 24 h with either 10 ?mol/L artemisinin or 1 ?mol/L artemisunate, the distribution of MCF-7 cells among S phase was reduced greatly, while inereased during G 0+G 1. However, artemisinin had weaker effect on the proliferation of MCF-7 cell, while artemisunate effectively inhibited the proliferation of MCF-7, the IC 50 was 0.31 ?mol/L. Apoptosis induced by 1 ?mol/L artemisunate was stronger than that by 10 ?mol/L artemisinin, too. Conclusion The inhibitory effect of artemisunate on the proliferation of tumor cell is stronger than that of artemisinin in vitro.

Purpose:To evaluate two different methods of radiotherapy, which affect the results of cervical cancers treated and complications of the rectum or bladder. Methods:From July 1991 to December 1996, 124 cases of cervical cancer were randomly allocated into two groups. Group A (59 cases:stage Ⅰ 1, Ⅱa 12, Ⅱb 30, Ⅲa 11, Ⅲb 5) received 45—55 Gy of external radiation(ER) to the parametrium and 50—65 Gy of intracavitary irradiation (4—5 Gy per fraction, 2 fractions per week). Group B(65 cases: stage Ⅰ 2, Ⅱa 15, Ⅱb 29, Ⅲa 10, Ⅲb 9) received 26—40 Gy ER to the whole pelvic and 30—40 Gy of intracavitary irradiation (4—5 Gy per fraction, 2 fractions per week), an additional 15—29 Gy ER to the parametrium. Results:In group A, 3 year and 5 year survival rates were 81.4% and 71.7%. In group B, they were 84.6% and 70.8%. The rates of complication for the rectum were 25.4%(3 year) and 21.7%(5 year) in group A, 10.8%(3 year) and 8.3%(5 year) in group B. The rates of rectal complication( P

Objective To investigate the risk factors of gallbladder neoplastic polyps,to determine the proper surgical indications,and to understand more about the clinical characteristics of gallbladder adenoma.Methods The clinical data of 748 patients diagnosed to have polypoid lesion of gallbladder (PLG) and underwent cholecystectomy from January 1998 to December 2012 in the Second Affiliated Hospital of Zhejiang University School of Medicine were retrospectively reviewed.Results Among 748 patients,340 had abdominal symptoms.Postoperative histopathology showed non-neoplastic polyps (n =659),gallbladder adenoma (n =68),gallbladder cancer (n =15) and no polyps (n =6).The mean diameters of the nonneoplastic lesions and the neoplastic polyps were (9.38 ± 3.44) mm and (14.55 ± 5.71) mm,respectively (P ＜ 0.01).The average age of the patients with non-neoplastic lesions was (44.14 ± 11.42) years and (47.39 ± 12.82) years in those with neoplastic polyps (P ＜ 0.05).The proportion of solitary PLG was 41.4％ (253/611) and 59.59％ (47/79) for the non-neoplastic lesions and the neoplastic polyps respec tively (P ＜ 0.01).The size of PLG (13.34 ± 4.18 mm vs.20.07 ± 8.19 mm,P ＜ 0.05) and the age of the patient (45.78 ± 11.66 years vs.54.13 ± 15.82 years,P ＜0.05) between the gallbladder adenoma and gallbladder cancer groups were significantly different.Gallbladder adenoma or dysplasia was identified in 66.7％ (10/15) of gal1bladder cancer specimens.Conclusions Patients with PLG and with abdominal symptoms,large size (≥ 10 mm),old age (≥50 y) and solitary polyp are indications for cholecystectomy.Gallbladder adenoma may develop to gallbladder cancer within 10 years.
