Objective To investigate the effects of liver function and tumor markers by nucleoside analogues Entecavir on patients with liver cirrhosis after hepatitis B.Methods 90 patients with liver cirrhosis after hepatitis B were selected, according to the different drugs were divided into experimental group and control group.Liver function and levels of tumor markers were compared after experiment.Results Two groups of patients with male to female ratio, average age, course of disease, no significant difference in general data of hepatitis B virus DNA content, comparable (P>0.05);Compared with the control group, the experimental group HBV DNA level is low, the negative rate was significantly higher (P<0.05);Compared with the control group, the experimental group ALT, AST and TBiL levels were significantly increased(P<0.05), ChE, AlB were significantly decreased (P<0.05);Compared with the control group, the experimental group CEA, AFP, CA125 and lower CA199 levels (P<0.05).Conclusion Nucleoside drugs can significantly improve liver function in patients with liver cirrhosis after hepatitis Band tumor markers indicators, and it is significance for treatment of liver cirrhosis after hepatitis.

Objective To explore the application value of ultra -high frequency ultrasound in detection of femoral artery stenosis in rabbits.Methods Twenty-four healthy male New Zealand white rabbits (body weight 2.5 -3.0 kg) were randomly divided into three groups , 8 rabbits in each group.Preparation of femoral atherosclerosis model : the rabbits were fed with high fat diet for 4 weeks, 8 weeks and 12 weeks after femoral artery balloon injury , respectively.The changes of cholesterol level were observed .We used ultra-high frequency ultrasonic probe to observe the femoral artery , to assess the diameter stenosis rate and peak systolic velocity (SPV) at the symptomatic side, and the histological areal stenosis was evaluated.Results 1.The blood cholesterol levels were increased after fed high cholesterol diet , with a significant difference among the groups (P <0.001); 2.There was a stenosis to a different degree in the modeling artery after fed high cholesterol diet for 4 wks, 8 wks, and 12 wks, and the stenosis degree was increased gradually .At 12 w, the degree of stenosis was higher than that at 4 w and 8 w, respectively, showing statistical significance ( P <0.001).At the symptomatic side, the peak systolic flow velocity was increased , and it was higher at 12 w than that at 4w and 8 w, respectively.3.With the extension of time, the arterial stenosis rate was increased along with the time course (P <0.05). Conclusions 1.High fat diet combined with balloon injury can cause varying degrees of rabbit femoral artery stenosis ; 2. Ultrahigh frequency ultrasound can clearly show different degrees of rabbit femoral artery stenosis , and can be used for detecting the lesions in animal models of peripheral vascular diseases .

ObjectiveTo explore causes and prevention experience for neuropsychopathic symptoms after liver transplantation.MethodsThe clinical data of 62 patients who underwent transplantation in our hospital were retrospectively analyzed for the causes of neuropsychopathy symptoms and treatment experience was Summarized.ResultsSixteen patients(25.8％ ) had psychiatric symPtoms after liver transplantation in three weeks,four of them more severe.The common clinical manifestation was sleep disorders,mania,anxiety,depression,delirium and change of cognition.The pre-operation encephalopathy history,liver function,blood loss,time in the ICU after surgery,post-operation infection and the concentration of immunosuppressive agents were risk factors for psychiatric symptoms.All patients were cured.ConclusionsPsychiatric symptoms are commonly seen after liver transplantation and have a variety of etiology and clinical manifestations.Psychological counseling should be strengthened.The appropriate therapeutic measures for different etiology can improve patient outcomes.

Objective To explore the value of the ultrasound contrast agent in conjunction with advanced contrast imaging techniques in the evaluation of the renal cortical perfusion. Methods The animal model was established with ligating renal artery to cause the renal cortical perfusion decrease of rabbits. Real-time harmonic gray scale imaging was performed to visualize the contrast enhancement of the renal cortex. After bolus injection of contrast agent SonoVue, dynamic image was observed and recorded during the first three minutes. According to the time-intensity curve (TIC), accelerating time (AT),Peak intensity (A), time to half of peak intensity (T), difference between peak and base (PBD), slope rate of the curve (β) and the product of A and β (A·β) were obtained before and after the renal artery operation. The t test and correlation analysis was used to examine the above parameters. Results Before the renal artery operation, renal cortex enhanced rapidly and obviously, the way of the enhancement was renal artery-cortex-pyramids. After ligation of renal artery, AT prolonged evidently (P<0.001), A decreased obviously (P<0.001), T obviously shortened (P<0.001), PBD decreased markedly (P<0.001), while the decline of βinduced (P<0.002) and A·βobvious dropped(P<0.001). AT, BPD and A·βcorrelated with stenosis level of renal artery. Compared with 31%－69% group, AT prolonged evidently (P<0.001). A decreased obviously (P<0.029), PBD decreased obviously (P<0.001), A·β was dropped markedly (P<0.02) in 70%-93% stenosis group. Conclusions Contrast agent combining with developed contrast specific imaging is able to detect changes of renal cortical microcirculation sensitively with the help of analysis of TIC.

ObjectiveTo study the protective effects of terlipressin on the renal function of recipients afterlivertransplantation.MethodsAmong 35casesreceivingorthotopicliver transplantation (OLT),16 cases were given terlipressin (group T):continuous infusion of terlipressin (1mg) into the vein immediately after the operation,twice every day for 3-4 days;19 cases were given dopamine and procaine (group D):continuous infusion of dopamine (40 mg) and procaine (0.5 g) into the vein immediately after the operation,twice every day for 3-5 days.In both two groups,the serum creatinine and urea nitrogen levels were normal before the operation. Serum creatinine,urea nitrogen,serum β2 microglobulin and urine amount were determined.ResultsSerum creatinine,urea nitrogen,serum β2 microglobulin and urine amount were increased significantly at 5th day after operation in both two groups (P＜0.05).As compared with group D,urea nitrogen and serum β2 microglobulin were decreased,while the urine amount increased significantly at 5th day after operation in group D (P＜0.05).Three cases (18.8％) in group T,and10 cases (52.6％ ) in group D developed RFALT at 5th day after operation (P＜0.05).ConclusionTerlipressin can protect the renal function of recipients after liver transplantation,and it can more effectively provide good recovery conditions for the recipients who develop RFALT after liver transplantation.

Objective To explore the clinical effect of evidence-based nursing in ventilator-associated pneumonia (VAP).Methods One hundred and sixty patients with mechanical ventilation in our ICU from January 2011 to June 2013 were randomly divided into the observation group and the control group.The control group received the traditional nursing,and the observation group received evidence-based nursing on the basis of the routine nursing.The time of invasive ventilation,the duration of ventilation,the off-line time,the occurrence time of VAP,and the incidence and mortality rates of VAP were compared between two groups.Results The time of invasive ventilation,the duration of ventilation,the off-line time,the occurrence time of VAP in the observation group were respectively (3.3 ± 0.6),(10.3 ± 3.8),(2.6 ± 4.3),(9.2 ± 2.8) d,and were significantly lower or later than (5.6 ± 3.1),(13.1 ± 3.4),(6.5 ± 4.8),(4.8 ± 2.7) d in the control group,and the differences were statistically significant (t =2.58,2.63,2.86,2.79,respectively; P ＜0.05).The incidence and mortality rates of VAP in the observation group were respectively 16.9％ and 10.4％,and were significantly lower than 48.1％ and 34.9％ in the control group,and the differences were statistically significant (x2 =5.36,4.93,respectively; P ＜ 0.01).Conclusions Evidence-based nursing can significantly shorten the time of invasive ventilation,the duration of ventilation and the off-line time; and can also effectively delay and reduce the occurrence of VAP.
