Aim To observe the action of estrone on the hippocampal neuronal apoptosis induced by NMDA in vitro and to analyse the mechanism underlying the neuroprotection of estrone. Methods The methods of both morphological analysis and cell viabilities were used, and Western blot was also used to analyce the role of antitoxiciy of estrone. Results The cultures were conformed with fluorescent dye of Hoechst 33258 and NeuN. About 31.6% neurons were induced into apoptosis by NMDA(300 ?mol?L~ -1 +glycine 5 ?mol?L~ -1 ,compared with control group, P0.05). MTT test also showed that estrone can protect cultures from apoptosis induced by NMDA, it can raise the cell viabilities exposed to NMDA. Western blot showed that activities of caspase-3 can be inhibited by estrone, the segments of caspase-3 can diminished after application of estrone together with NMDA. Conclusion Estrone had neuronal protection, this role maybe relate to the inhibition of caspase-3, a common pathway in apoptosis. The results can provide some clues to the explovation of the clinical use of estrone and to the development of a neuronal protective drug.

Objective To observe the eriects of integrated traditional Chinese and western medical nursing on postoperative complications of rectal cancer.Methods 56 patients with rectal cancer treated with Miles operation were randomly divided into a control group and a treatment group.The control group was nursed with conventional western medicine,and the treatment group was nursed according to syndrome differentiation of TCM plus conventional western medicine.Results The postoperative complications of the treatment group were significantly fewer than the control group.Conclusion Integrated traditional Chinese and western nursing of perioperative patients with rectal cancer can reduce complications and improve quality of life of patients.

Objective To observe effects of integrated western and Chinese nursing on postoperative complications of breast cancer. Methods 53 patients with breast cancer who were treated with radical mastectomy, were randomly divided into two groups. The control group was treated with conventional western medicine nursing, and the treatment group was treated with syndrome differentiation nursing based on the control group. The postoperative complication of two groups was observed.Results The postoperative complication of the treatment group were significantly lower than the control group.Conclusion Integrated western and Chinese nursing of perioperative patients with breast cancer, can reduce complications and improve quality of life of patients.

Based On current situation of experimental teaching and managementin our college,this paper raised some concrete approaches of imlxoving experimental teaching levels to strengthen lab construction and experimental teaching quality

With the development of neuroimaging the detection rate of basilar artery tortuosity is significantly high.The occurrence and development processes of basilar artery tortuosity are affected by age,basilar artery length,vertebral artery dominance,and other factors.Basilar artery tortuosity may influence the blood supply of posterior circulation and cause brainstem and cranial nerve pressure leading to clinical symptoms.

By analyzing the problems existing in the practice of doctor -patient communication , respectively discusses the speech act theory before the implementation of the implementation of doctor -patient communication oral English training , implementation , and after implementation of the positive role: instant help medical students to master a large number of medical English vocabulary;In view of the students come from different areas , instant help correct the pronunciation and intonation;Benefit based on speech act theory to guide the student to carry on the different roles played in English oral practice helps students to adopt direct and indirect speech act theory and the method of the oral English practice for communication;To improve medical students′professional recognition;To strengthen the medical students′sense of mission .

OBJECTIVE:To observe the clinical efficacy of compound glycyrrhizin combining desloratadine in the treat?ment of chronic urticaria.METHODS:103patients with chronic urticaria were randomly divided into treatment group which were treated with compound glycyrrhizin plus desloratadine and controlled group which were treated with single desloratadine.The courses of treatment for both groups were2weeks.RESULTS:The total effective rates of the treatment group and the controlled group were96.15%and82.35%,respectively.There were significant differences between the2groups(P

Objective To explore the occurrence, clinical feature and the associatrd factors of Sjogren' s syndrome(SS) complicated with Idiopathic Pulmonary Fibrosis(IPF) to build up knowledge for early diagnosis. Methods The clinical characteristics of 160 cases damitted SS patients collected from January 2002 to August 2008 were retrospectively investigated including RF, chest - X, ESR, blood -gas analysis,pulmonary function tests,chest HRCT,ANA and so on. Results The patients with IPF accounted for 33.12% of total SS patients, including 12 cases of male. These patients presented strongly positive ANA,strongly positive RF etc,especially in the male. Conclusion The occurrence of SS - IP was related to the disease' s activity. FHRCT and pulmonary function test should taken early in order to get early diagnosis and treatment.

Objective Applying a reliable precise method to assess the mitotic index of cardiomyocytes,to disclose of disclosure the mechanism implicated in cardiomyocytes proliferation. Methods H9c2(2-1) cardiomyocytes were originally developed from rat BD1X heart(ATCC).These cells were cultured on coverslips.Double immunofluorescence staining with monoclonal antibodies(1:100) against phospho-histone H3 and ?-sarcomeric actin was performed on the cultured cells.Anti-mouse IgG FITC was used as the secondary antibody for the H3P antibody,and anti-mouse IgM Cy3 was used as the secondary antibody for the ?-sarcomeric actin.DNA was visualized with Hochest 33342.All photographs were taken with an Olympus fluorescence microscope. Results The cytoplasm of cardiomyocytes appeared red,the mitotic chromosomes green with distinct shape,and Hochest 33342-stained nuclei blue.Conclusion Our method is the reliable and exact means to observe and assess cardiomyocytes mitosis.
