The relation between the critical radius and the particle size distribution for generalized Ostwald type ripening processes whereby the mass transfer coefficient is modelled by a power law was derived. The critical radius is determined by the growth rate, the mass transfer coefficient and the mass balance, and is independent of whether the limiting stationary growth regime has been obtained.

Objective To investigate the efifcacy of interferon alpha (IFNα) followed by nucleotide analogues (NAs) treatment in patients with negative hepatitis B e antigen (HBeAg), undetectable serum HBV-DNA and low hepatitis B surface antigen (HBsAg) levels.Methods The enrolled HBeAg-negative chronic hepatitis B patients had undetectable HBV-DNA level (HBV-DNA<1000 copies/mL for at least 12 months) and low HBsAg level (HBsAg≤2000 U/mL) with long-term NAs treatment. These patients switched their therapy sequentially from NAs regimens to IFNα for 48 weeks. The treatment response was evaluated in terms of serum HBV DNA load, serological HBV markers, liver function tests and routine blood test before treatment and 12, 24 and 48 weeks of treatment. The patients were followed up for 24 weeks after treatment. The primary endpoint was HBsAg loss or seroconversion and HBsAg<10 U/mL. Logistic regression analysis was conducted to examine relevant predictive factors. Receiver operating characteristic curve was used to evaluate the value of prior HBeAg seroconversion and on-treatment HBsAg dynamics in predicting HBeAg seroconversion than in HBsAg persistence group (χ2=9.527,P=0.002). HBsAg loss was more likely in the patients who had HBsAg decline at least 0.5 log U/mL from baseline at week 12 of treatment (χ2=16.576,P<0.001). The area under the ROC curve for prediction of HBsAg loss was 0.810 (95 %CI, 0.686 to 0.935,P<0.001).Conclusions The HBeAg-negative chronic hepatitis B patients with positive virological response and low HBsAg level after NAs treatment are more likely to achieve HBsAg clearance when switched to IFNα treatment. Prior HBeAg seroconversion and on-treatment HBsAg dynamics are useful in predicting and guiding IFNα sequential therapy.

Objective To investigate the effects and mechanism of different dosage of fluvastatin on the prevention of heart muscle ischemia reperfusion injury in rabbits.Method Thirty-five rabbits were randomly divided into 5 groups with 7 rabbits in each: sham group,myocardial ischemia reperfusion control group,low dosage of fluvastatin pretreatment group (2 mg/kg,Group F1),middle dosage of fluvastatin pretreatment group(5 mg/kg,Group F2) and large dosage of fluvastatin pretreatment group(20 mg/kg,Group F3).The left ventricular systolic pressure(LVSP),the max rate of rise of left ventricular pressure(?dp/dt_(-max)) and left ventricular end-diastolic pressure(LVEDP) were detected during the experiment.At the end of reperfusion,the infarct size and area at risk were defined by Evans blue and TTC staining,and the levels of myocardial nitrogen monoxidum(NO) and nitricoxide synthase(NOS) were measured.Result Compared with the ischemia reperfusion group,the indexes of heart function improved significantly,the level of myocardial NO was increased significantly and the myocardial infarct size was decreased significantly in the groups F2 and F3.There was no significant difference between the group F1 and ischemia reperfusion group.Conclusion Fluvastatin exerts a cardioprotective effect against myocardial ischemia reperfusion injury in rabbits.NO is likely involved in this protective mechanism.

Objective To survey the current status of job stressor and exhaustion among nursing staff in the catheter room of grade Ⅲ-A general hospitals and to look for regularities.Methods 178 nursing staff coming from catheter room,operating room,and outpatient department of Shenzhou Hospital and Fengtian Hospital accepted questionnaires of Chinese Nursing Stressor Scale and Exhaustion Scale in Spring 2010.Results Chinese Nursing Stressor Scale indicated that scores of subitem and total score of job stressor in the catheter room were significantly higher than those in the outpatient department; however,there were no significant differences in scores of subitem and total score of job stressor between catheter room and operating room.On the other hand,Exhaustion Scale showed that scores of emotional exhaustion and job unconcerned feeling in the catheter room were significantly higher than those in the outpatient department,but scores of job achieved feeling in the catheter room were significantly lower than those in the outpatient department.There were no significant differences in Exhaustion Scale between catheter room and operating room nurses.Conclusions Job stressor and exhaustion were serious among nursing staff in the catheter room of grade Ⅲ-A general hospitals,which should cause the attention of management department.

AIM: To investigate the effects of fluvas-tatin on expression of intercellular adhesion molecule-1 after myocardial ischemia-reperfusion in rabbits with hyper-lipidemia. METHODS: 30 rabbits which were gastric perfusion administered intralipid were randomly divided into 3 groups ( n - 10 in each) : IR ( ischemia-reperfusion) group, S (sham-operation) group and F (fluvastatin 10 mg?kg-1 ) group. Electrocardiography and cardiac function were recorded during the experiment. At the end of reperfusion, ischemic area and infarct size were defined by Evans blue and triphenyltetrazolium chloride staining. The expression of ICAM-1 in myocardium was measuredby RT-PCR. RESULTS: After ischemia-reperfusion, the expression of ICAM-1 mRNA in myocardial and infarct size decreased and cardiac function significantly improved in F group compared with IR group. CONCLUSION: The increase of expression of ICAM-1 mRNA in myocardial may be one of the important factors in inducing myocardial ischemia-reperfusion injury. The myocardial protective mechanism of fluvastatin maybe attribute to its effect on decreasing the expression of ICAM-1 mRNA in myocardial .
