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 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 .

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 investigate the feasibility of differentiating human umbilical cord blood stem cells into hepatocytes. Methods Thirty-six BALB/c nude mice were randomly divided into experimental group and control group(18 in each of the group), and experimental group was again randomly divided into group A, B and C (six in each of the group). The mice in experimental group and control group were exposed to 350 cGy radiation produced by 60Co. After 3 h, karyocytes at different concentrations in the fresh human umbilical cord blood were injected into the mice in experimental group A, B, C via their tail veins, and the equal volume of normal sodium (NS) was also injected into control group via tail veins. After one month, carbon tetrachloride (CCl4) was injected into experimental group A, B and control group via abdominal cavity, and the equal volume of normal sodium was injected into experimental group C. After two months, immunohistochemistry and reverse transcriptase polymerase chain reaction (RT-PCR) were used to detect the expressions of human cytokeratin-18 (CK18), cytokeratin-19 (CK19) and albumin (ALB) in liver tissues of all mice. Results The expressions of CK18, CK19 and ALB in injured liver tissues were all positive, and the expressions of experimental group B were higher than those of experimental group A (P

?AlM: To evaluate the clinical effects of excimer laser phototherapeutic keratectomy ( PTK) assisted by anterior segment optical coherence tomography ( OCT ) in the treatment of corneal anterior diseases.
?METHODS:There were 28 eyes of 15 patients who were diagnosed as corneal anterior diseases, on which excimer laser phototherapeutic keratectomy was performed from September 2012 to September 2013. The patients were checked up by anterior segment OCT before operation forauxiliarily judging types and depths of the disease to direct setting parameters such as cutting depths and diameters etc. in PTK. Follow-up of 6mo were included in this study. They were observed cornea condition, uncorrected visual acuity, spherical equivalent and haze at 6, 15d, and 1, 2, 3 and 6mo post-operatively.
?RESULTS: At postoperation, corneal condition of all patients were impoved more or less, that is, the outbreak was under control, or seizure frequency decreased obviously. There were no statistic differences between preoperation and postoperation on the changes of uncorrected visual acuity, spherical equivalent and haze (P>0. 05).
? CONCLUSlON: ln patients with corneal anterior diseases, excimer laser phototherapeutic keratectomy assisted by anterior segment OCT in the treatment of corneal anterior diseases can get rid of the lesion effectively and accurately and receive better treatment effect. But it is necessary to control the cutting depth avoiding postoperative hyperopia.

AIM: To analyze the associated factors of poor vision after phacoemulsification operation.
METHODS:Clinical data of cases with poor vision after cataract phacoemulsification combined with IOL implantation from 341 patients(418 eyes) during Jan. 2015 to Jan. 2016 in our hospital were collected and logistic correlation analyzed.
RESULTS: The incidences of postoperative low vision were 10. 3% for one month after operation. Forty-three eyes were reported low vision, and 41 of 43 the patients with postoperative low vision had fundus oculi disease before operation, which included 20 eyes ( 48. 8%) with age-related macular degeneration, 16 eyes(39. 0%) with diabetic retinopathy, 3 eyes ( 7. 3%) with glaucomatous optic neuropathy, 1 eye(2. 4%) with pathologic myopia of retinopathy and 1 eye ( 2. 4%) with branch retinal vein occlusion.
CONCLUSION: The associated factors of poor vision after phacoemulsification operation are preoperative eye diseases and the nuclear hardness, and preoperative eye diseases may be the main causes of postoperative low vision. Comprehensive examination should be attached importance to, and be careful in the operation to decrease the harm for visual performance.
