Objective Objective To study the application of oral ranitidine to MRCP. Methods 20 healthy subjects, including 12 males and 8 femals, were performed with random double-blind MRCP examination by 1.5T MR machine. Two experienced radiologist assessed the results. Results Without any side effect, the proximal end and distal end of the common bile duct, bile-cyst were displayed well (P

Multi-drug resistance (MDR) of cancer cells is a major cause of failure of chemotherapy in cancer treatment. Most MDRs are caused by overexpression of P-glycoprotein (P-gp) which effuses chemotherapeutic agents out of cells. Nano drug delivery systems (NDDS) have been valued for their characteristics including drug targeting, slow-releasing, and long circulation time in the body. Through mechanisms such as non-specific endocytosis and receptor-mediated endocytosis, NDDS can inhibit P-gp at the gene and protein level, leading to improved concentrations of chemotherapeutic drugs in cancer cells, and therefore reverse MDR.

Objective To observe the effects of camellia oil on the development of allergic contact dermatitis in mice. Methods Mice models of allergic contact dermatitis were established with dinitrofluo-robene (DNFB). Then, certain concentrations of camellia oil and halcinonide were used topically on the ears of mouse models twice daily for 6 days. Skin specimens were obtained from the treated ears and subjected to histology examination and pathological analysis. RT-PCR was performed to detect the mRNA expressions of interleukin 2 (IL-2) and interferon γ (IFN-γ) in the skin tissues. Results Allergic contact dermatitis was successfully induced by DNFB in mice with a marked increase in the mRNA expression of IL-2 and IFN-7. There was a slight decrease in the ear swelling degree, inflammatory reaction intensity, number of infiltrating inflammatory cells, and pathological severity in camellia oil-treated mice and halcinonide-treated mice compared with glycerinetreated mice. Camellia oil and halcinonide also induced different degrees of reduction in the mRNA expression of IL-2 and IFN-γ in inflammatory tissues. Conclusion Camellia oil can alleviate the pathological damage and down-regulate the expression of IL-2 and IFN-7 in mice with DNFB-induced allergic contact dermatitis.

Since 2007,in order to comply with the hospital's strategic development and construction of the subjects,our hospital treat the research project management as the starting point,through the establishment of a sound project management and funding approaches; strengthen project process management,implement the total quality control; use of information technology tools to improve project management effectiveness.After several years of implementation,the number of our hospital's research projects above provincial and ministerial level has gradually increased,manyhigh level of SCI papers are emerging,and discipline construction has also been effectively carried out,all of which have promotedour research strength,the development of medical teaching and research.Therefore,we will continue to strengthen project management,and fully mobilize the initiative staff awareness of service,make full use of scientific information systems in future scientific research management to boost hospital disciplines.

The authors analyzed the current predicament of medical human resources and seek the deficiencies and problems that exist in the medical moral education system .Based on this , this paper pointed out that it should change the medical ethics education ideas , enhance medical ethics cultural identity; based on the health industry demand , broaden the content of the medical ethics education;to develop a new mode of medical ethics education , perfect the evaluation system of medical ethics and health industry demand , provide new guidance for medical eth-ics education .

Objective To investigate the application effect of quality control management in the prevention of indwelling catheter associated urinary tract infection in intensive care unit (ICU) patients. Methods Cases of patients stayed in the department of ICU undergoing indwelling catheter over 10 d were selected by using time stage sampling method. Totally 136 cases of patients were selected from January 1, 2012 to December 31, 2012, as the control group. A total of 145 cases of patients were selected from January 1, 2013 to December 31, 2013, as the performance group. Cases in performance group were taken standardized training and quantify the performance appraisal on the basis of measures in the control group. The urine routine was tested and bacterial was cultured at indwelling catheter 3 d, 7 d and 10 d, respectively. The indwelling catheter associated urinary tract infections of the two groups were compared. Results After the implementation of the performance appraisal management, the incidences of indwelling catheter associated urinary tract infection at 3 d, 7 d and 10 d were 4.8%(7/145), 19.3% (28/145) and 32.4% (47/145), respectively. Within each quarter, the incidence of indwelling catheter associated urinary tract infection was rising with indwelling catheter time prolonged. And the incidences of the first and second quarter were higher than three and four quarter. The incidences of indwelling catheter associated urinary tract infections at 3 d, 7 d and 10 d in the performance group were lower than the control group, the differences were statistically significant (χ2=4.494, 30.660 and 49.307, P < 0.05). Conclusions Standardized training of nursing staff in ICU and implementation of performance appraisal management could effectively improve the enthusiasm and sense of responsibility of the nurses, and effectively reduce the incidence of indwelling catheter associated urinary tract infection.

Background and purpose:The incidence of lung cancer with brain metastasis tends to go up. The technique of intensity-modulated radiotherapy (IMRT) with simultaneous integrated boost (SIB) for tumor bed is a new treatment choice for patients with brain metastasis. This study aimed to investigate the feasibility of IMRT combined with SIB for tumor bed in the treatment of brain metastases of lung cancer by exploring its short-term clinical effect and treatment-related toxicities.Methods:Thirty-two patients who were diagnosed as having lung cancer with 1-4 brain metastases were prospectively collected. All the brain metastases were treated with whole brain 5 ifelds IMRT (40 Gy/20 f) combined with SIB (50 Gy/20 f). The dosage distribution within the target volume and dose-volume histogram were evaluated. Meanwhile, the overall response rate of radiotherapy, thelocal tumor control rate, 1-year survival rate, treatment-related acute and late toxicities were also calculated.Results:All patients were treated with IMRT successfully. The rate of Grade 2 vomitting, nausea, epilepsy was 9.4%, 15.6%, and 12.5%, respectively. Two cases had Grade 2 cognitive impairment, 4 cases had Grade 2 memory injury, and 2 cases had Grade 3 memory injury. There were no any Grade 4 events of acute and late toxicities. The overall response rate of radiotherapy was 71.9%. The local tumor control rate was 96.9%, and 1-year survival rate was 44%.Conclusion:It is feasible to use 5 ifelds IMRT (40 Gy/20 f) combined with SIB (boosting 10 Gy, i.e. total dose 50 Gy/20 f) for the treatment of brain metastases of lung cancer.
