Objective To investigate the expression of Ki-67 antigen and Survivin in epithelial ovarian tumor and their relationship.Methods Immunohistochemical assay SP method)was used to examine the expression of Ki-67 antigen and Survivin in 24 cases of benign and 47 cases of malignant epithelial ovarian tumor.Results The staining reaction of Ki-67 was mainly confined to the cellular nucleus.Ki-67 index in malignant tumor(19.59?16.48) was significantly higher than that in benign epithelial ovarian tumor(0.17?0.20)(P

Objective To observe the effects of triptolide(TPL) on the anti-oncogene-APC gene of acute lymphoblastic leukemia cell line Jurkat in vitro. Methods The effects of TPL on proliferation Jurkat cells were assayed by using cell culture, MTT. The effects of TPL on APC gene of Jurkat cells were analyzed by nested methylation specific PCR and RT-PCR. The effects of TPL on the proteinum expression of APC gene were detected by Western blotting analysis. Results Following the treatment of TPL, the cell proliferation rate was degraded as the treatment concentration increased and the culture time extended. The effects were dose and time-dependent. The 48 hour IC50 was 19.7 ng/ml. TPL can reverse hypermethylation of APC gene,and induce the expression of the mRNA and the proteinum. Conclusion Low dose TPL could depress the proliferation rate of Jurkat. The possible mechanism might be its reversing the hypermethylation of APC gene and activiting the expression of APC gene.

Objective To investigate the proliferation inhibition and the apoptosis induction effect of brucine on human chronic myeloid leukemia cell line HL-60 cells.Methods HL-60 cells were exposed to various dosages of brucine 24,48,72 h respectively,MTT method was used to assay the growth inhibition effect of brucine on HL-60 cells and the IC50 of brucine was evaluated at the same time.The morphology was observed by AO/EB stains.The cell apoptosis and cell cycle was tested by flow cytometry with Annexin V-FITC/PI double staining and PI labeling respectively.Results The results indicated that the brucine displayed significant anti-proliferative effect on HL-60 cells in a dose-and time-dependent manner,with IC50 value of 211.8 μg/ml(24 h),107 μg/ml(48 h),83 μg/ml(72 h)respectively.The most significant inhibition was observed at 320 μg/ml for 48 h.In this condition,apoptosis morphology was induced by brucine with nuclear chromatin condensation,most of the nuclears were orange stained and condensation-like or bead-like,which was consistent with the Annexin V-FITC/PI results.The cell apoptosis rates were(2.1±1.1)%,(21.3±1.2)%,(38.6±1.3)%,(58.5±4.1)%,(75.3±0.87)%and(66.2±0.75)%in different dose of brucine,respectively.At the same time,the cell cycle analysis results showed that the cell ratio in G0/G1 phase was decreased while in G2/M and sub-G0 phases was increased,comparing with blank control group.Conclusion Brucine can inhibit cell growth dramatically,which may be related to the cell apoptosis and the cell cycle arrest.

Objective To assess the efficacy and safety of intracoronary stenting in the acute phase of unstable angina pectoris (UAP). Methods Fifty-five patients with UAP were randomized to early (Group Ⅰ, n=29) and delayed interventional treatment (Group Ⅱ, n=26). Coronary angiography and stenting were performed within 48 hours in Group Ⅰ and 7-10 days later in Group Ⅱ. Procedural success rate, time interval from admission to angina relief and duration of hospitalization were recorded. Cardiac events within 30 days were observed as well. Results Clinical characteristics and angiographic features were similar between the two groups. There was no significant difference in the procedural success rate (93% versus 96%), but the cardiac event rate within 30 days was significantly lower in Group Ⅰ than in Group Ⅱ (0% versus 9.2%, P<0.05). The time interval from admission to angina relief (4.4±3.1 days versus 5.7±2.9 days) and the duration of hospitalization (8.8±3.2 days versus 13.5±3.1 days) were significantly reduced in Group Ⅰ (both P<0.05). Conclusions Intracoronary stent implantation is effective and safe in the acute phase of UAP. Early percutaneous coronary intervention results in rapid improvement in symptomatology and a shorter hospitalization. Its long-term effect has to be confirmed in a future randomized study.

Objective To study the effect of alprostadil combined with epalrestat and methylcobalamin in the treatment of type 2 diabetic peripheral neuropathy.Methods From January 2014 to June 2016,120 patients with type 2 diabetic peripheral neuropathy in the First People's Hospital of Baiyin were randomly divided into two groups according to the random number table method.64 patients of the observation group were given the treatment of alprostadil,epalrestat combined with methylcobalamin.56 patients of the control group were given the treatment of alprostadil and methylcobalamin.And the two groups were treated for 4 weeks.The blood glucose,clinical symptoms,adverse reaction,nerve conduction velocity index were compared between the two groups before and after treatment.Results The fasting blood glucose and 2-hour postprandial blood glucose of the two groups after treatment were significantly decreased (t =18.20,17.61,15.75,23.69,all P < 0.05),and the conduction velocity of the common peroneal nerve,the median nerve and the ulnar nerve in the observation group were significantly higher than those in the control group (t =1.989,2.638,3.026,2.187,2.619,1.997,all P < 0.05).The total effective rate of the observation group was significantly higher than that of the control group(95.3% vs.82.1%,x2 =4.54,P <0.05).There were no statistically significant differences in the blood glucose and the incidence rate of adverse reactions between the two groups (t =0.267,0.176,0.695,0.658,x2 =1.356,all P > 0.05).Conclusion Alprostadil combined with epalrestat and methylcobalamin in the treatment of type 2 diabetic peripheral neuropathy has good effect.
