Objective To investigate the effects of quercetin on the proliferation of mammary cancer cell in vitro. Methods Effects of quercetin on the cell proliferation was tested in ER-positive MCF-7 cell and ER-negative MDA-MB231 cell by MTT measurement. And to evaluate the estrogen-like effect of quercetin and its relation with the estrogen-receptor by pure estrogen receptor antagonist ICI 182, 780 as a tool. Cell cycle was examined by flow cytometry. Result Quercetin (10～50 ?mol/L) stimulated proliferation of ER-positive MCF-7 cell compared with solvent control, whereas ER-negative MDA-MB231 cell proliferation effect was inhibited, and the cell cycle was impulsed from G1 to S, DNA synthesizing was inhanced, PI was also increased. The above function on boosting MCF-7 cell proliferation can be inhibited by adding estrogen receptor antagonism ICI182, 780. Conclusion Quercetin has the estrogen-like activities through the estrogen response pathway.

To investigate and analyze the factors which influence the public attitudes towards autopsy after accidental deaths.The study has carried on an investigation among 386 individuals in random,with a questionnaire named "The cognition of the public whether to carry on the autopsy after accidental deaths".Using the statistical methods of the Logistic Regression analysis and optimum regression analysis to analyze the recycling questionnaires.Through the diagnosis,we found there are four main factors which influence public opinion upon the autopsy after accidental deaths,the knowledge of autopsy,the believing in autopsy,years of schooling and family financial circumstances.

Objective To study the inhibitory effects of wild-type p53 on gastric cancer cell lines BGC-7901 and to explore the importance of wild-type p53 in gene therapy for gastric cancer. Methods Adenoviral vector with exogenous wild-type p53 gene was transfected into the gastric cancer cell line BGC-7901 which harbours a mutation in codon 204 of the p53 gene.The transfer efficiency and expression effect of p53 were examined by immunohistochemistry and in situ hybridization. The growth of BGC-7901 cells in vitro was determined by cell counting and MTT assay. Flow cytometric analysis was used for observing cell cycle.Results Transfer efficiency reached 100% in BGC-7901 cells when adenovirus infection ability was over 100MOI. 3 days after transfection, the introduction of exogenous wild-type p53 into the tumor cells resulted in decreased expression of the protein of mutant p53 and increased level of mRNA of wild-type p53 gene. The growth of the BGC-7901 cells was significantly slower after transfection with wild-type p53 gene than that before transfection. The percentage of G 1/G 0 phase of the cells with exogenous wild-type p53 gene was much higher than that of the cells without exogenous wild-type p53 gene.It was 56 47% and 79 40% respectively(P

Objective To investigate the changes of urinary brush border membrane enzymes and serum cystatin C (Cys C) in newborns in order to develop early diagnostic indicators for sclerema neonatorum (SN) renal dysfunction.Methods Sixty-night cases with sclerema neonatorum and 30 cases of normal newborns were enrolled in this study.Of all sclerema neonatorum cases,39 cases were mild and 30 cases were moderate to severe sclerema neonatorum.Immunoca talytic assay method was adapted to detect the level of urinary brush border membrane.The levels of serum Cys C,blood urea nitrogen (BUN),creatinine (Cr) and urinary β32 microglobulin (β2-MG) in two groups were also measured.Results The levels of urinary brush border membrane enzyme,β2-MG and serum Cys C in sclerema neonatorum group were (40.09 ± 7.29) U/L,(4.65 ± 1.33) mg/L and (1.84 ± 0.32) mg/L,higher than those in control group ((23.19 ± 5.62) U/L,(2.49 ± 0.77) mg/L and (1.07 ± 0.25) mg/L; t =10.34,7.47 and 10.55,P ＜ 0.01).The levels of urinary brush border membrane enzyme and serum Cys C in moderate to severe sclerema neonatorum group were (42.06 ± 7.59) U/L and (1.93 ± 0.34) mg/L,higher than those in the mild group ((38.57 ± 6.70) U/L,(1.77 s0.29) mg/L;t =2.24,2.11,P ＜0.05).The abnormality rates of urinary brush border membrane enzyme and serum Cys C in sclerema neonatorum group were 79.7％ (55/69) and 72.5％ (50/69),higher than β2-MG abnormal rate (52.2％ (36/69),x2 =12.95,12.11,P ＜ 0.01).In sclerema neonatorum group,urinary brush border membrane enzyme was positively correlated with β2-MG (r =0.560,P ＜ 0.01),and serum Cys C was positively correlated with BUN,Cr (r =0.314,0.287,P ＜ 0.05).Conclusion Renal injury is common in SN.Urinary brush border membrane enzyme and serum Cys C are served as the diagnostic parameters for early detection of renal injury in SN.

Objective To evaluate the relationship between the expressions CyclinD1 and nm23H1 and the response to neoadjuvant chemotherapy (NACT) in cervical carcinoma. Methods 100 patients with cervical cancer were enrolled in this study. These patient were randomly divided into two groups. The observed group were treated by neoadjuvant chemotherapy followed by radical hyterectomy and lymphonectomy. The other 50 cases were treated by operation as control group. The expression of CyclinD1 and nm23H1 were examined by immunohistochemistry using post-operation specimens. Results The total response rate of neoadjuvant chemotherapy was 75 %( CR+PR). The expression rate of CyclinD1 was 76 % in experimental group, and 54 % in control group(P 0.05). Conclusion The neoadjuvant chemotherapy was helpful for the patients with local advanced stage of cervical carcinoma. CyclinD1 may be one of the path of NACT, but nm23H1 may not related to NACT.
