Objective To explore the effect of different doses of anthracycline on preoperative chemotherapy of breast cancer.Methods In 40 cases of breast cancer patients using small doses of anthracycline therapy, and classified as the control group, the other 40 patients using high-dose anthracycline therapy, and classified as observation group.Then observe two groups of patients were compared;the patients were in our hospital from January to December 2016 were treated.Results The total effective rate was 82.5% in the observation group and 62.5% in the control group, the difference between the two groups was statistically significant (P<0.05).The incidence of adverse reactions in the observation group was 0, the control group was 27.5%, and the incidence of adverse reactions in the two groups was statistically significant (P<0.05).Conclusion Different doses of anthracyclines on the clinical effect of chemotherapy before surgery for breast cancer research found that different the clinical effect of different doses produced by E100C and E75C, E100C can improve the treatment effect of the patients, and reduce the occurrence of toxicity, so it is worthy of reference.

Objective To study the mechanism of FTY720 on type Ι diabetic rats. Methods The typeⅠdiabetes rat model was established by feeding male SD rats with high energy urea and injecting into the abdominal cavity with low dose cephalosporins (STZ, 30 mg/kg). In the following, the treated rats were divided into two groups: model group and FTY720 group. Another group of untreated rats was assigned as normal control group. FTY720 group was given 1 mg/kg FTY720, the normal control group and model group was given the equal amount of water. Results The cardiac function of FTY720 group was recovered markeyly. FTY720 activated the expression of vascular endothelial cells S1P1 , diabetes and reduced the expessions of S1P3 and PKCβ Ⅱand it restored the migration ability of diabetes cardiovascular endothelial cell , as well as the abnormally elevated cardiovascular endothelial cells induced by high sugar permeability. Conclusion The S1P1 and S1P3 cut is an important reaction pathway to the complications of diabetes and cardiovascular dysfunction. FTY720 may reduce the damage to core blood vessels caused by diabetes , and pathological angiogenesis which functionally depends on the PKCβⅡ signaling pathways. Therefore, FTY720 may provide a potential therapy for cardiovascular function impaired by diabetes.

Inhibitory effects of the O - ( 1 - ethoxvl - butyl ) berbarmine (EBB) on cultured fibroblast was studied by observating calmodulin (CaM ) content of cultured fibroblast with ELISA and DNA content at each phase of cell cycle with flow - cvtometerv. The CaM con-tent in the test group . compared to control . decreased markedly and DNA content increased significantly in the G0+Gi phase but reduced in the S phase. These results suggested that inhibitory mechanism of EBB on fibroblast proliferation may be closely related to CaM decrease in cells.

The course arrangement,teaching contents and means and other items were investigated and analyzed in this research of teaching evaluation of professional teachers in military medical university.The results showed that the levels of post-oriented education teaching were increasing in updating ideas and accumulating experiences in recent years.However,there still existed a few problems such as too much basal theories,lack of real army circs in the contents and little practice in the manners.Therefore,the quality of post-oriented education in military medical university is expected to be developed to a higher level.

Objective:To evaluate the expression of vascular endothelial growth factor C(VEGF-C),Epstein-Barr virus(EBV) latent membrane protein 1(LMP1),cyclooxygenase-2 (COX-2) in nasopharyngeal carcinoma(NPC).Method:LMP1, COX-2 and VEGF-C were detects by immunohistochemical staining for 57 case NPC tissue.Result:The positives rates of LMP1,COX-2 and VEGF-C detected by immunohistochemical staining were 49.1%(28/57), 75.4%(43/57)and 59.6%(34/57), respectively. The expression of LMP1, COX-2 and VEGF-C were correlated to each1 other in NPC(P<0.05).Conclusion:LMP1 and COX-2 may induce expression of VEGF-C directly or LMP1 induce expression of VEGF-C by induce COX-2 expression, may contribute to lymph metastasis and develop NPC.

A questionnaire was used to survey the perspective of the 22 mentors,24 students, 27 graduate students and 27 public health units on the competence of MPH student. The result showed that the practice skill,analyzing skill,program plan and practice skill,and emergency reaction abil-ity got more attention. This suggested that to the training of MPH,the training objective should focus on the ability to resolve problems; the curriculum should focus on the characters of public health and on the practice training.

Objective To assess the feasibility of laryngeal mask anesthesia under spontaneous ventilation in pulmonary resection with uniportal video-assisted thoracoseopic.Methods Forty patients with pulmonary masses were randomized into two groups(n =20 in each group) to undergo pulmonary resection with uniportal videoassisted thoracoscopic,full implementation of thoracoscopic lobectomy and mediastinal lymph node dissection.Patients in two groups were induced by intravenous anesthesia,and the skin of the fifth intercostal space were infiltrated with ropivacaine.Patients in two both groups were maintained by intravenous ancsthesia and sevoflurane anesthesia.Muscle relaxants were administered in endotracheal inmbation group but not in the LMA group.Patients in the LMA group and tracheal intubation group underwent with spontaneous breathing and one-lung ventilation respectively.Results No significant differences were found in surgery time,intraoperative lowest SpO2,preoperative PaCO2,1-h postoperative blood gas analysis between the two groups.The anesthesia induction time,extubation time,and the stay time for the recovery of anesthesia and postoperative hospital stay were significantly shorter than those in the tracheal intubation group.The increments in MAP and HR after intubation operation were smaller than those in the LMA group.The total dosage of sulfentanyl and propofol per kg in the LMA group were significantly less than those in the control group.The PaCO2 after pulmonary resection and the intraoperative maximum level of PETCO2 in the former group were significantly higher than those in the tracheal intubation group,however the incidence of throat discomfort and the hospitalization cast were significantly decreased.Conclusion In view of patient rehabilitation and in hospitalization cast,laryngeal mask anesthesia under spontaneous ventilation in uniportal video-assisted thoracoscopic surgery was better than the procedure performed under intubation anesthesia.

OBJECTIVE To find out the main commonly encountered pathogen and antibiotic resistance in hospital infection in Department of Neurosurgery. METHODS Clinic samples from Jun 2005 to Jun 2007 were collected and drug sensitive test was taken.RESULTS The most commonly encountered pathogens of infection were Gram-negative bacillI(83.1%),including Klebsiella pneumoniae(25.0%),Escherichia coli(19.1%),andAcinetobacter baumannii(10.3%). The three kinds of pathogens had heavy resistance to at least 8 kinds of antibiotics. The resistance rates to imipenem and ofloxacin were the lowest (6.8% and 32.4%). CONCLUSIONS The pathogens isolated from Departmentof Neurosurgery are Gram-negative bacilli which have multiple antibiotic resistance. The key prevention measures of infection are to control prophylatcic usage of the third generation cephalosporins,strengthen environmental microbial monitoring,hand sterilization and cleaning among the medical staff.

Objective To investigate the effects of rehabilitation intervening in different stage on activities of daily living of old stroke patients. Methods 74 old cases were divided into 3 group according to the time from onset of stroke to rehabilitation intervention: group A (＜3 months), group B (3～6 months), and group C (>6 months). They were treated with routine rehabilitation for 2 months and assessed with Barthel Index before and after rehabilitation. Results All the patients improved their ADL significantly after rehabilitation (P=0.000), and those in group A improved more than in group C (P<0.05). There was no significant difference between group A and B, and group B and C (P>0.05). Conclusion The rehabilitation can effectively improve the ADL of old stroke patients. The early the rehabilitation intervenes, the better the ADL is.

Objective To analyze and compare efficacy and safety of different chemotherapy regimens in the treatment of elderly patients with advanced gastric cancer. Methods 60 elderly patients admitted to our hospital with advanced gastric cancer were selected as research subjects , and divided into experimental group and control group depending on the treatment of chemotherapy. The experimental group were treated with Gio oxaliplatin (SOX), and patients in the control group accepted Olivier Elizabeth, leucovorin and fluorouracil (FOLFOX6) treatment. Compare and analyze the efficacy of the two groups after two cycles of therapy. Results By chemotherapy, recent efficiency and disease control rate were not significantly different (P>0.05) between the two groups;and there was also no significant difference in the incidence of adverse reactions,such as adverse reactions, fatigue weakness, gastrointestinal reactions, hand-foot syndrome, oral mucositis (P > 0.05). Conclusion The efficacy was equivalent between FOLFOX6 chemotherapy SOX test group and the control group in the treatment of elderly patients with advanced gastric , and there was no significant difference in the incidence of adverse reactions.
