Aim To investigate the anti-proliferative effect of salinomycin on doxorubicin-resistant human breast cancer MCF-7 /DOX cells.Methods MCF-7 and MCF-7 /DOX cells were treated or untreated with salinomycin.Cell viability was detected by MTS assay. Cell apoptosis was detected by Annexin V-FITC /PI as-say.Reactive oxygen species (ROS)was measured by DCFH-DA staining.Mitochondrial membrane potential was measured by JC-1 assay.The expression of apopto-sis related proteins BAX, BCL-2, caspase-3, and caspase-9 were evaluated by Western blot analysis. Results The cell viability was significantly reduced by salinomycin treatment in a dose-dependent manner. The flow cytometry results showed that salinomycin in-duced MCF-7 /DOX cell apoptosis,increased ROS pro-duction,and decreased mitochondrial membrane poten-tial.Furthermore,salinomycin decreased the expres-sion of BCL-2,and increased the expression of BAX, cleaved caspase-3,and cleaved caspase-9.Moreover, the antioxidant N-acetylcysteine (NAC ) markedly blocked the above effects.Conclusions Our results suggest that salinomycin-induced apoptosis in MCF-7 /DOX is associated with induction of ROS production, and activation of mitochondria apoptosis pathway, which may become a potential chemotherapeutic agent for the therapy of doxorubicin resistant breast cancer.

Objective: To make it clear whether there exists m elatonin receptor in the thyroid of human embryo. Methods: Thyr oid was collected and sliced up to be stained with methods of immunohistochemis try and in situ hybridization. Results: The thyroid tissue w as p ositively dyed, melatonin receptor mt1 and MT2 were with both immunohistoche mistry and in situ hybridization while brown granules dep osited in the membrane, plasma and nuclear of the thyroid cell were with the imm unohitochemistry. Conclusion: There exists melatonin rece ptors in human embryo thyroid, either mt1 or MT2, and they exist in the memb rane, plasma and nuclear.

We review the proceedings on the methods of how the aromatase inhibitor maintains its function, the recently developed drugs and the progress in the field of endocrine therapy for human breast cancer

Objective: To make it clear whether there exists melatonin receptor in the thyroid of human embryo. Methods: Thyroid was collected and sliced up to be stained with methods of immunohistochemistry and in situ hybridization. Results: The thyroid tissue was positively dyed, melatonin receptor mt 1 and MT 2 were with both immunohistochemistry and in situ hybridization while brown granules deposited in the membrane, plasma and nuclear of the thyroid cell were with the immunohitochemistry. Conclusion: There exists melatonin receptors in human embryo thyroid, either mt 1 or MT 2, and they exist in the membrane, plasma and nuclear.

Objective To investigate the risk factors for postoperative cognitive dysfunction (POCD) and nursing intervention in patients undergoing laparoscopic radical hysterectomy. Methods One hundred patients undergoing laparoscopic radical hysterectomy were included, surgical history, general anesthetics way, education, family factors(alone), body mass index, age, duration of anesthesia, dose of sufentanyl, hematocrit, the time for regaining orientation, dysphoria, postoperative pain degree were recorded. The occurrence of POCD was observed at 7 days (early period) and 3 months (later period) after surgery. Logistic regression analysis was used to examine the risk factors for POCD at early period and later period. Results The incidence of POCD at early period was 29.0%(29/100). Logistic regression analysis of surgical history, general anesthetics way, body mass index, age, hematocrit, the time for regaining orientation, postoperative pain degree in patients, general anesthetics way (OR=2.821, 95%CI 1.099-7.240) and postoperative pain degree(OR=2.292, 95%CI 1.129-4.654) were the significant risk factors for POCD at early period. The incidence of POCD at later period was 7.0%(7/100). Logistic regression analysis of education and family factors(alone) in patients, family factors(alone) was the significant risk factor for POCD at later period (OR=5.517, 95%CI 1.010-30.126). Conclusions General anesthetics way and postoperative pain degree are the significant predictors for POCD in patients undergoing laparoscopic radical hysterectomy during hospitalization, and family factors(alone) is the risk factor for POCD at 3 months after surgery, and active nursing intervention could reduce the occurrence of POCD.

Objective To investigate the value of MRI combined with serum CA125 test in the diagnose of ovarian tumor.Methods To investigate the MRI and serum CA125 level of healthy control group (40 cases),benign tumor group (52 cases),and the malignant tumor group (43 cases).Results Of 95 patients with ovarian masses,CA125 was detected in the malignant patients with the sensitivity of 79.3 ％,specificity of 72.6 ％ and accuracy of 75.1％.MRI was 73.8 ％,81.2 ％,and 82.6 ％ respectively.Combined with CA125 and MRI was 69.4 ％,97.3 ％,and 88.6 ％.Youden' s index of combined detection was significantly higher than single detection (MRI combined with CA125 and single MRI u =1.97,P =0.012 5,and CA125 u =1.96,P =0.012 0).Conclusion MRI combined with CA125 could improve the accuracy of diagnosis ovarian neoplasm in clinic.

Objective To investigate the relationship of glycoprotein serglycin (SRGN) expression with invasion and metastasis of breast cancer cells,and the role of microRNA in the regulation of SRGN expression.Methods Real-time quantitative polymer ase chain reaction (PCR) and Western blot were used to detect the differences in SRGN expression between higher metastasis Michigan cancer foundation-7 (MCF-7)/5-Fu breast cancer cell lines and weaker metastasis MCF-7 cell line.The siRNA interference experiment and in vitro Transwell experiment were used to detect effect of SRGN on the ability of invasion and metastasis of breast cancer cells.Bioinformatics software was used to predict miRNAs targeting SRGN,and integrated microRNA differentially expressed chip data between breast cancer cell MCF-7 versus MCF-7/5-Fu.The miRNA quantitative PCR was used to determine the differences of candi date miRNA expression.After transfection of microRNA minics,Western blot was used to test candidate microRNA target SRGN.Transwell experiment was used to test the effects of candidate microRNAs on tumor cell invasion and metastasis.Results SRGN was increased significantly in MCF-7/5-Fu cells,and the invasion and metastasis of tumor cells were inhibited when SRGN was interfered.In addition,miR181 b/c expressed in MCF-7/5-Fu cells was reduced significantly,negatively correlated with SRGN expression,and targeted SRGN expression.It inhibited invasion and metastasis of tumor cells.Conclusions MicroRNA181b/c inhibits metastasis of breast cancer by targeting SRGN.

Objective:To evaluate the effect of sacral nerve stimulation (SNS) for STC by receptor tyrosine kinase c-kit.Methods:Wistar rats were fed with diphenoxylate to make slow transit constipation(STC) rat model.Sacral nerve stimulation(SNS) for the SNS Rat Group.The studied animals were allocated into three experimental groups:STC Rat Group;SNS Rat Group;Normal Rat Group;Every group included 10 rats.The c-kit of ICC in the subserosal layer of rats were analyzed by immunohistochemistry,western blot and RT-PCR.Results:The morphological characteristics of STC Rat Group were not comparable to those of the multipolar c-Kit positive ICC seen in the subserosa of colon of normal rat.In the colon of rat,c-kit protein and c-kit gene in SNS rat group and Normal rat group was significantly higher than STC rat group detecting by western blot.Statistical differences between STC Group and SNS Rat Group were found (P＜0.05);statistical differences between STC Group and Normal Rat Group were also found (P＜0.05).There was not statistical differences between SNS rat group and Normal Rat Group.Conclusion:SNS has effective treatment for the STC rat.
