This paper introduces such information of database server platform for military ″1″ hospital information system as its history, present status and progress. The IA-64 calculation platform based on open standard and Oracle 9i are also summarized. Upgrade experiment and evaluation are carried out, which all lay the foundation for the following upgrade of the server platform and can be referred to on relative functions.

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 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.

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 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.

The main component of the tea is tea polyphenols, which can inhibit the processes of carcinogenesis and development of a variety of human cancers by diverse mechanisms. Further research may provide us with more information about the anticancer activities of these promising compounds and facilitate the usage in cancer prevention and treatment.

This article unscrambled the concept of pathogenesis theory,through textual research of literatures,directly explained the concept connotation.From the relationship between pathogenesis and symptom differentiation and the innovation of pathogenesis theory of doctors in past dynasties,it demonstrated the possibility that pathogenesis theory was the innovation breakthrough point of traditional Chinese medicine theory.It proposed the conjecture that pathogenesis was the "saddle point" "sensitive point" of traditional Chinese medicine is theory,and proposed several assume about pathogenesis theory study.
