Objective To investigate induction of apoptosis of human ovarian cancer CoC1 cells by 5-allyl-7-gen-difluoromethylenechrysin(ADFMChR)in vitro,and its molecular mechanism. Methods The proliferative and growth inhibition of CoC1 cells treated with ADFMChR was respectively measured using(3,4,5-dimethylthiazol-2-yl)2,5-diphenyl tetrazolium bromide(MTT)colorimetric assay and clone-formation in soft agar assay. The apoptosis of CoC1 cells induced by ADFMChR was determined by DNA agarose gel electrophoresis assay. Effect of ADFMChR on PPAR-γ, Bcl-2. Bax protein expression level of CoC1 cells was detected by western blotting. Results The proliferation of CoC1 cells could be significantly inhibited by ADFMChR in a dose-dependent manner. The IC50 was 7. 76 μmol/L The ladder-shaped band could be shown in DNA agarose gel electrophoresis after treatment with ADFMChR at 30. 0 μmol/L for 48 h and the ladder-shape band disappeared with GW9662. Western blot analysis showed that expression of PPAR-γ and Bax proteins were up-regulated and protein levels of Bcl-2 were depressed after treatment with ADFMChR in a concentration-dependent fashion. However,the effects of ADFMChR on Bcl-2 and Bax proteins were blocked or diminished in the presence of GW9662. Conclusions The effect of ADFMChR on induction of apoptosis in CoC1 cells may be mediated by activation of PPAR-γ, sequentially accompanied by reducing of protein levels of Bcl-2 and increasing of Bax expression.

To investigate the relationship of between p21wAF1 and PCNA expression and the patients' prognosis in breast carcinoma. MethodExpression of p21wAF1 and PCNA was determined by S-P immunohistochemical technique in 152 patients with breast carcinoma. ResultsPositive immunostaining of p21WAf1was detected in 61(40.1% ) primary breast carcinoma, in which 43(70.5% ) were low expression, and 18(29.5% ) over expression of 152 PCNA positive cases, 69(45% ) expressed with low index and 83(55% )expressed with high index. p21wAf1 expression level was correlated with tubule formation (γs＝ 0.341, P＜0.01 ),nuclear atypia(γs=0.516, P＜0.01), mitosis(γs=0.351, P＜0.01)and histological grade(γs=0.415, P＜0.01)in breast cancer tissue. Univariate analysis demonstrated less disease-free survival in patients with higher p21WAF1 (x2 = 6.92, P＜ 0.01 ) and PCNA (x2 = 5.14, P＜0.05)expression than in those with lower expression. The survival term of the patients with p21WAF1 -/PCNA low index, p21wAF1 +/PCNA low index, p21WAF1 +/PCNA high index and p21WAF1 -/PCNA high index groups was successively shortened. Conclusions( 1 ) Combined detection of p21wAF1/PCNA is helpful to judge the proliferating activity of the tumor cells and the patients prognosis. (2) Different expression level of p21WAF1in breast carcinoma is probably related the different regulating directions.

Objective To detect the expression of human epithelial growth factor receptor 2 (HER-2) in advanced lung adenocarcinoma with epithelial growth factor receptor (EGFR) mutation, and to explore the potential of HER-2 as a therapeutic target for drug resistance in patients with EGFR mutations. Methods HER-2 is commonly expressed in the advanced lung adenocarcinoma with EGFR mutations, mainly in the cell membrane. Results The overexpression rate of HER-2 protein in tissues of advanced lung adenocarcinoma with EGFR mutations was 33.3%(28/84). The overexpression rate of HER-2 protein in patients>50 years of age was 40.3%(27/67), which was significantly higher than that of patients ≤50 years of age [5.9 % (1/17)], the difference was statistically significant (χ2=7.227, P=0.007). The overexpression rate of HER-2 protein in patients with high pathological differentiation [44.4 % (8/18)] was higher than that in patients with poor pathological differentiation [30.3%(20/66)], but the difference was not statistically significant (χ2=1.273, P=0.259). The overexpression of HER-2 protein in patients with EGFR 21 exon mutation [40.5 % (17/42)] was significantly higher than that of EGFR19 exon mutation [25.0%(10/40)], but the difference was not statistical significance (χ2=2.222, P=0.136). Conclusions The overexpression rate of HER-2 protein in advanced lung adenocarcinoma patients with EGFR mutation is high, which is related to the age and tumor differentiation. HER-2 is expected to be a potential therapeutic target for drug resistance patients with EGFR mutations.

Objective To investigate the mechanism of Mi-362 targeting Six1 inhibiting proliferation and migration of cer-vical cancer cells. Methods The expression levels of microRNA-362 in cervical cancer tissues and adjacent tissues were measured in 142 patients with cervical cancer in our hospital. At the same time,Hela cancer cell group,microRNA-362 mimics group and mi-croRNA-362 inhibitor group were set up to determine the viability of cancer cells,the number of monoclonal formation of cancer cells,the apoptotic rate of cancer cells,cell cycle,the number of perforations,and the levels of microRNA-362 and Six1 in cervical cancer fluid of Hela. Results The expression level of miR-362 in cervical cancer tissue was lower than that in adjacent tissue(P<0. 05). The higher the infiltration of lymphatic vessel space,pathological stage,TNM stage,lymph node metastasis and depth of infil-tration,the lower the expression rate of miR-362(P<0. 05).

The number of clones formed in the miR-362 mimics group was lower than that in the Hela cancer cell group(P<0. 05),and the number of clones formed in the miR-362 inhibitor group was higher than that in the Hela cancer cell group and the miR-362 mimimics group(P<0. 05). The apoptotic rate of miR-362 mimics group was higher than that of Hela cancer cell group(P<0. 05),and that of miR-362 inhibitor group was lower than that of Hela cancer cell group and miR-362 mimics group(P<0. 05). The G1 phase in the miR-362 mimics group was higher than that in the Hela cancer cell group(P<0. 05),and the G1 phase in the miR-362 inhibitor group was lower than that in the Hela cancer cell group and the miR-362 mimimics group(P<0. 05). The number of cell membrane penetration in the miR-362 mimics group was lower than that in the Hela cancer group(P < 0. 05),and that in the miR-362 inhibitor group was higher than that in the Hela cancer group and the miR-362 mimimics group(P<0. 05). The expression level of miR-362 in the miR-362 mimics group was higher than that in the Hela cancer cell group(P<0. 05),and the expression level of miR-362 in the miR-362 inhibitor group was lower than that in the Hela cancer cell group and the miR-362 mimics group(P<0. 05). The expression level of Six1 in the miR-362 mimics group was lower than that in the Hela cancer cell group(P<0. 05),and that in the miR-362 inhibitor group was higher than that in the Hela cancer cell group and the miR-362 mimics group(P<0. 05). Conclusion miR-362 plays an important inhibition in the occurrence and development of cervical cancer,and its mechanism is related to the inhibition of prolifer-ation,migration and invasion of cancer cells by microRNA-362 through negative regulation of Six1.

Objective:To explore the clinical effects of early bed-out intervention based on enhanced recovery after surgery (ERAS) in elderly patients with hip fracture.Methods:Totally 80 patients with hip fracture admitted in Zhejiang Taizhou Hospital from January 2017 to December 2018 were selected and divided into observation group ( n=40) and control group ( n=40) according to the random number table. Patients in the control group received conventional nursing care, while patients in the observation group received early ERAS-based bed-out interventions. The incidence of adverse events, including pulmonary infection, abdominal pain and constipation, was compared between the two groups within 2 weeks. Postoperative hip joint function, daily living activities and quality of life were evaluated in the two groups. Results:The incidence of pulmonary infection, urinary tract infection, bloating, constipation and deep vein thrombosis (DVT) in lower limbs in the observation group was lower than that in the control group, and the difference of total complication rate was statistically significant ( P<0.05) . The hip joint function, daily life activity and quality of life scores in the observation group were higher than those in the control group, and the differences were statistically significant ( P< 0.05) . Conclusions:Early ERAS-based bet-out interventions taken for elderly patients with hip fracture can reduce the incidence of postoperative adverse events, and improve their hip joint function, daily activities and quality of life.
