Objective:To investigate the effect of TFu on FRH-0201 cell and to test new drugs for the chemotherapy of cholangiocarcinoma.Methods:Morphological changes were observed by light microscopy and fluorescence microscopy.The effect of TFu on FRH-0201 cell was examined by clone formation.Cell cycle and apoptosis were examined by flow-cytometric analysis.DNA ladder was used to detect apoptosis.To compare the drug susceptibility of TFu with 5-Fu and several other common drugs by MTT colorimetric assay.Results:TFu significantly inhibited the proliferation and clone formation of FRH-0201 cell line within concentration of 0.016~4mmol/L.The inhibition ratio was dependent on ascending concentration and time,and that is higher than 5-Fu with the same concentration.The morphological character of apoptosis was observed.Flow cytometric analysis indicated that TFu induced a G_1 phase arrest and apoptosis more than 5-Fu.ADM,DDP and TFu were the sensitive drugs to FRH-0201 cel line,and the combination of them can reach the highest inhibition ratio.Conclusion:These results suggests that TFu can more significantly inhibited the proliferation of FRH-0201 cell line than 5-Fu.The mechanism may be related to the cell cycle arrest in association with apoptosis,which may provide a new approach for treating cholangiocarcinoma.

Objective To discuss influence of evidence-based nursing on compliance and quality of life of patients with coronary heart disease after percutaneous coronary intervention (PCI). Methods From January to September, 2010, 86 patients with coronary heart disease undergoing percutaneous coronary intervention therapy were randomly divided into the study group and the control group with 43 patients in each group. Two groups of patients underwent percutaneous coronary intervention therapy and routine care after related check-up, and the study group was given comprehensive and systemic evidence-based nursing intervention on the basis of routine care. Medical compliance and life quality and other clinical indicators of the two groups of patients were comparatively analyzed. Results Compared with the control group, fully compliance rate of the study group was significantly higher, and partical compliance rate decreased significantly. At the same time, score of neurological function, psychological function, social function and other aspects of material life were significantly increased in the study group. Conclusions Application of evidence- based nursing has significant meaning for improving compliance and life quality of coronary heart disease patients undergoing percutaneous coronary intervention, which is worthy of further clinical promotion and application.

OBJECTIVE: To establish a RP-HPLC method for concentration determination of m-nisoldipine (m-Nis) in the plasma of rhesus monkeys.METHODS: The analysis was performed on a C18 column at 30℃ with a mobile phase of methanol-water (63∶37) at a flow rate of 1.0ml/min.The detection wavelength was 236nm.The sensitivity was 0.05AUFS and the internal standard was nimoldipine.RESULTS: The detectable concentration of m-Nis showed good linearity in the range of 1.75～ 448?g/L.The average recovery of extraction was 84.1%(RSD=4.09%), and the average recovery of method was 98.7%(RSD=2.76%).The processed plasma samples remained stable in quality after having been stored for 7 days, and the plasma remained stable in quality through repeated freeze thawing or stored at low temperature.CONCLUSION: The present method is highly sensitive and reproducible, as well as convenient, which can be used for concentration determination of m-Nis in the plasma of rhesus monkeys.

Objective:To compare suicide attempters with community-based controls for more specific prevention strategies.Method:From the list of suicide attempters of three general hospitals 2 years before, 363 of 786 attempters (48.5%) were found. We collected a control group matched for sex, age and location of residence and compared the life events for the past two years, life quality, family cohesion and adaptability of the past month, and impulsivity and aggressiveness.Result:The two groups were similar in sex, age, family income, marital status, occupation and health insurance status. But the suicide attempt group had less education, had more prominent impulsive and aggressive in traits, had higher levels of hopelessness, more negative life events and greater distress from negative life events in the two years after their attempt. They had poorer life quality and lower family cohesion and adaptability for the past month. They had also more severe depressive symptoms in the prior week.Conclusion:Two years after their suicide attempt, the attempters still have substantial differences from normal controls. They are a distinct high-risk subgroup that deserves specific interventions.
