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 clinical efficacy of sequential plasma perfusion of low dose plasma exchange in the pa-tients with acute on chronic liver failure (ACLF).Methods The patients with HBV related ACLF in the infection department of the Affiliated Hospital of Luzhou Medical College were divided into the plasma exchange therapy group (group A,n=114)and the low dose plasma exchange sequential plasma perfusion therapy group (group B,n=144).The group A was treated only by plasma exchange of fresh frozen plasma 2 400 mL;while the group B adopted the sequential plasma perfusion of plasma exchange,with fresh frozen plasma dosage of 1 400 mL.The changes of the liver and renal function,coagulation function and electrolyte indicators were observed in the two groups.The differences in the clinical effects and adverse reactions were compared between the two groups.Results The serum levels of ALT,TBIL and INR after treatment in the two groups were significant decreased than before treatment(P<0.05);ALB and PTA were significantly improved compared with before treatment(P<0.05);there were no signif-icant differences in serum levels of CRE,K+ and Na+ between before and after treatment.The changes of various indexes before and after treatment had no statistical differences between the two groups.The total effective rate and the mortality at 24 weeks in the group B was 66.66% and 47.22% respectively,which had no statistical differences compared with the group A.The total oc-currence rate of adverse reactions in the group B was 23.75%,which was significant lower than 35.26% in the group A with statis-tical difference (P=0.011).Conclusion Sequential plasma perfusion of plasma exchange has better clinical effect and few adverse reactions for treating the patients with ACLF,which can reduce the plasma dosage significantly.

Objective To investigate the change characteristics of serum ferritin(SF)and parathormone (PTH)levels in differ-ent stages of chronic kidney disease(CKD)and their correlation with serum beta 2-microglobulin(β2-MG).Methods The levels of serum PTH,SF andβ2-MG in different stages of CKD were detected and the detection results were compared with those in the con-trol group.The correlation between serum SF and PTH withβ2-MG in each stage of CKD was analyzed.Results The level of ser-um PTH,SF andβ2-MG in the compensation group had no statistical difference compared with the control group (P >0.05),while which had statistical differences among the decompensation group,renal failure group and uremia group (P <0.05)The correlation analysis showed that serum PTH was positively correlated with serumβ2-MG in 145 cases(r=0.92,P <0.05),and the serum SF level was also positively correlated with serumβ2-MG level(r=0.92,P <0.05).Conclusion Detecting serum PTH,SF andβ2-MG levels possesses the important clinical significance for understanding CKD condition and prognosis.

Objective To evaluate two kinds of anterior screw fixations in the treatment of odontoid fractures. Methods A total of 36 patients with D' Alonzo type Ⅱ odontoid process fractures were treated with anterior screw fixation in our department from 1999 to July 2009. There were 28 males and 8 females at mean age of 42.3 years (rang 17-59 years). According to time and surgery procedures, the patients were divided into Group A ( from 1999 to June 2005, n = 11 ) and Group B ( from June 2005 to July 2009, n = 25 ). Patients in Group A received anterior hollow screw fixation of the odontoid process monitored under G-arm or C-arm, while those in Group B received anterior screw fixation of the odontoid process assisted by Iso-C 3D navigation system. The operation time and blood loss in two groups were compared by Student' s t test and analyzed with SPSS 13.0 statistical software. X-ray examination was performed in all patients 3, 6 and 12 months after operation to observe fracture union and stability of the upper cervical spine. Results The operation time was ( 102 ± 12) min ( range, 77-148 min) in Group A and ( 104 ± 14) min ( range, 71-150 min) in Group B, with no statistical difference ( P =0.21 ). The blood loss was (465 ± 5) ml (range, 20-130 ml) in Group A and (42 ± 6) ml (range, 26-150 ml) inGroup B, with no statistical difference (P = 0.16). All patients received reexamination three months after operation, which showed no bony union or dislocation but average 40% restriction of neck rotation. One year after operation, 30 patients (83%) got fracture union and six ( 17% ) got fiber healing, with average 24% restriction of neck rotation. Conclusions There is no statistical significant differences between two groups in aspects of operation time, blood loss and fracture healing. But anterior screw fixation of the odontoid process assisted by Iso-C 3D navigation system can reduce exposure to radiation of both patients and surgeons. Furthermore, solid screws can be applied to augment the fixation intensity and thereby reduce the complications caused by non - union.
