Objective:To investigate the present situation of medical students′medical ethics education and fur-ther to put forward countermeasures for medical colleges and universities. Method:With the methods of question-naire, literature and interview, medical students of the second grade and above in Xi′an Jiaotong University, Xin-jiang University and Xinjiang Medical University were investigated. SPSS 20. 0 was used to establish a database and frequency analysis method was used to analyze data. Results:It is suggested that some medical students′ motiva-tion to be a doctor is pure and the professional ethical identity is correct. There exist problems in the evaluation of ethics anomie behaviors. The students lack of cognition of medical ethics but pay more attention to medical technol-ogy. Most of the medical students think that clinical practice education and the model demonstration of teachers are conducive to medical ethics education. Conclusion: Universities can develop their own medical ethics education mode through various forms of classroom education, the involvement of old professors in teaching, strengthening learning of medical laws, daily ideological education by counselors and the construction of campus spiritual civiliza-tion.

Objective To analyze implementation outcomes of the new health reform policy at a provincial hospital for the past six months.Methods Trend analysis,factor analysis and ratio analysis approaches were used in monthly surveillance,along with comparative study of the data before and after the reform,to probe into impacts of the new policy on hospital operations.Results Medical income increased by 22.09％,mainly contributed by volume growth (22.28％) of medical services; Medical income dropped by 0.16％ due to pricing policy factors; medicine proportion deceased by 4.84％; following the reform,the income per outpatient and inpatient increased by 12.32％ and 5.35％ respectively.Conclusion Following the drug zero profit policy and rise of the charging standards for medical treatment service at the hospital,the growth of total income mainly comes from growing volume of medical services instead of pricing policy factors.The new health reform is conducive to optimizing the hospital's income structure and raising value to doctors' technical service.

Objective To explore the effects of inducible co-stimulator (ICOS) gene on the cytotoxic activity of cytokine-induced killer (CIK) cells against cholangiocarcinoma cells. Methods CIK-ICOS cells were obtained by stable transfecting ICOS genes into CIK cells through the adenovirus vector whereas untransfected and EGFP-transfected CIK cells were treated as controls. The proliferation and apoptosis of different CIK cells, as well as their cytotoxicity against cholangiocarcinoma cells in the three groups were detected. The expressions of IFN-T, IL-2 and TNF-α in the supernatant of different CIK cells were measured by ELISA. SCID mice with cholangiocarcinoma were randomly divided into CIK group, CIK-EGFP group, CIK-ICOS group and normal saline group. The cytotoxic activity of CIK-ICOS cells against cholangiocarcinoma cells in vivo was observed. Results CIK-ICOS cells displayed better proliferation than CIK cells and CIK-EGFP cells. At day 20 and 23 of culture, the apoptosis rate of CIK-ICOS cells was 0.69% and 0.89%, respectively, while that of the CIK cells was 2.90% and 4.92%. The cytotoxic effect of CIK-ICOS cells at different E: T ratio against cholangiocarcinoma cells was significantly stronger than that of CIK cells and CIK-EGFP cells (F=13.37, 6.46, 25.51, P<0.05). The concentration of IFN-γ in CIK-ICOS cultured supernatant was (49.50±4.73)μg/L, which was significantly higher than that in the cultured supernatant of CIK cells [(30.53±3.73)μg/L] and CIK-EGFP cells [(30.12±2.64)μg/L](F=38.89, P<0.05). The growth of cholangiocarcinoma was significantly slower in CIK-ICOS group than that in CIK group and CIK-EGFP group, whereas the necrosis area of tumor was larger and the CIK cells in CIK-ICOS group was more than those in the other two groups. Conclusions CIK cells had the function of killing cholangiocarcinoma cells in vitro and in vivo. After ICOS genes were transfected into CIK cells, the survival time of CIK cells in vitro was prolonged and the proliferation of CIK cells was enhanced, as well as the secretion of IFN-γ was increased so that the cytotoxicity of CIK cells against cholangiocarcinoma cells in vitro and in vivo was enhanced.

Objective To study the clinical,pathological and genetic features of myofibrillar myopathy caused by BAG3 gene mutation.Methods The clinical features and pathological findings of a patient with myofibrillar myopathy were analyzed.Genomic DNA of the patient was extracted from peripheral blood and the next generation sequencing was performed to explore the mutation of genes about myopathies.Results The patient presented with nine-year-old onset myopathy characterized by progressive difficulty for squatting,rigid spine and muscle atrophy in the limbs symmetrically.Peripheral neurogenic damages were found on electromyography.On muscle biopsy,myogenic and neurogenic damages with rimmed vacuoles appeared,and the deposited materials were positive for sarcoglycan,dystrophin-R and dystrophin-C.There was a reported heterozygous mutation in the exons of the BAG3 gene (c.626C ＞ T).Conclusion There is no specificity of clinical manifestation in myofibrillar myopathy,and the diagnosis of this disease mainly depends on muscle biopsy and genetic screening.

OBJECTIVE To investigated the impact of age,sex and season on the morbidity of allergic rhinitis(AR)and noninfectious,nonallergic rhinitis(NINA).METHODS The clinical data of the patients with AR and NINA was analyzed from Oct.2003 to Oct.2005.Factors such as age,sex, etc were taken into consideration.RESULTS The highest morbidity age of AR was 10～19 years, and that of NINA was 30～39 years.The morbidity of allergic rhinitis in men was higher than that in women before 20 years old,while there was no sexual difference of nonallergic rhinitis.About 61.6% of patients diagnosed with AR developed their condition before 20 years old,about 66.5% of patients diagnosed with NINA developed their condition after 20 years old.The number of patients with AR increased markedly from July to November, while there was no seasonal diversity of NINA. CONCLUSION There were obviously differences between AR and NINA of age,sex and seasons, which implied different pathologic mechanism between these two types.

OBJECTIVE: To observe the efficacy of allergen blocking nasal spray (ABNS) , combined with seawater spray (SS) and myrtol standardized capsules (MSS), in patients with rhinitis sicca. METHOD: Patients diagnosed as rhinitis sicca were randomly divided into 2 groups: ABNS+SS group and SS group. In ABNS+SS group, patients used ABNS and SS four times per day and MSS twice per day. In SS group, patients used the same medicine except ABNS. Both group were observed for 14 days. The visual analog scale (VAS) of dryness, the endoscopy evaluation score (EES) and the tolerability of the spray were compared between the 2 groups. RESULT: There were 30 patients included in each group. The VAS and EES were improved in both groups after 2 weeks' treatment. The improvement of VAS and EES in ABNS+SS group was significantly superior to SS group (VAS: P < 0.01, EES: P < 0.05). There were only 2 patients complaint of slight discomfort when using ABNS, which did not disturb the treatment. CONCLUSION There is good efficacy of allergen blocking nasal spray (ABNS), combined with seawater spray (SS) and myrtol standardized capsules (MSS), in patients with rhinitis sicca.
