Objective To investigate the prognostic factors for patients with hepatitis B virus-related acute-on-chronic liver failure,and to provide a basis for clinical diagnosis and treatment.Methods A total of 172 patients with hepatitis B virus (HBV)-related acute-on-chronic liver failure who were admitted to The First Hospital of Jilin University from January 1,2006 to January 1,2016 and had complete medical records and follow-up data were enrolled,and a retrospective analysis was performed for their clinical data and laboratory markers to determine prognostic factors.The independent-samples t test was used for comparison of continuous data between groups,the chi-square test was used for comparison of categorical data between groups,and a multivariate logistic regression analysis was performed for the indices determined to be statistically significant by the univariate analysis to screen out independent risk factors for the prognosis of patients with HBV-related acute-on-chronic liver failure.Results The multivariate logistic regression analysis was performed for the indices determined to be statistically significant by the univariate analysis,and the results showed that the prognostic factors were total bilirubin (TBil),prothrombin time activity (PTA),Na +,total cholesterol (TC),Child-Turcotte-Pugh (CTP) score,age ≥50 years,the presence of liver cirrhosis,bilirubin-enzyme separation,and complications.The multivariate regression analysis was performed for the complications determined to affect prognosis by the univariate analysis,and the results showed that the complications as risk factors were hepatic encephalopathy,hepatorenal syndrome,and infection.Conclusion TBil,PTA,Na +,TC,CTP score,age ≥50 years,the presence of liver cirrhosis,bilirubin-enzyme separation,and complications are independent risk factors for the prognosis of patients with HBV-related acute -on-chronic liver failure.Liver failure patients with hepatic encephalopathy,hepatorenal syndrome,and infection tend to have poorer prognosis.Therefore,early judgment of the prognosis of patients with liver failure is of great importance in the prevention and treatment of related complications.

In this paper, according to the requirement of the focused sound field measurement, a focused sound field measurement system was established based on the LabVIEW virtual instrument platform. The system can automatically search the focus position of the sound field, and adjust the scanning path according to the size of the focal region. Three-dimensional sound field scanning time reduced from 888 hours in uniform step to 9.25 hours in variable step. The efficiency of the focused sound field measurement was improved. There is a certain deviation between measurement results and theoretical calculation results. Focal plane--6 dB width difference rate was 3.691%, the beam axis--6 dB length differences rate was 12.937%.

To investigate vincristine-induced dopaminergic neurons toxicity and mechanism, and explore the molecular target to reduce the toxicity, zebrafish was chosen as a model animal, based on RT-PCR, Western blotting, whole mount in situ immunofluorescence and other technical means. The results showed that the transcription levels of tyrosine hydroxylase gene and dopamine transporter protein gene were inhibited. Furthermore, the number of dopaminergic neurons was decreased by vincristine. Autophagy was suppressed and beclin1 gene expression was inhibited in a dose-dependent manner by vincristine in larval zebrafish. Up-regulated beclin1 partly reduced vincristine-induced neurotoxicity, and down-regulated beclin1 increased toxicity. Beclin1 plays an important role in vincristine-induced dopaminergic neurons toxicity.

Objective To observe the change characteristics of serum prealbumin and cholinesterase in the liver cirrhosis pa-tients ,and to discusses the determination of these two indicators in diagnosis ,treatment and prognosis of clinical significance in pa-tients with liver cirrhosis .Methods A total of 45 liver cirrhosis patients diagnosis in our hospital from July to December 2013 were recruited into study group ,at the same time 98 healthy people were recruited into control group .The Hitachi 7170 automatic bio-chemical analyzer was used to detected serum prealbumin and cholinesterase ,the former was detected by immunoturbidimetry meth-od ,the latter was detected by butyryl glucosinolates choline bottom method .The levels and abnormal rates of the two indicators be-fore and after treatment in the study group were compared with those of the control group .Results The serum prealbumin and cho-linesterase at different stage in the study group were significant lower than those of the control group(P<0 .05) .The abnormal rate of serum prealbumin after treatment was significant different with those among and before treatment in patients with cirrhosis (χ2 =10 .08 ,P<0 .05) ,but there were no significant difference on cholinesterase(P>0 .05) .Conclusion The serum prealbumin is a sensitive indicator of liver cell damage ,its change could reflect the condition of treatment and development status ,which has im-portant clinical significance on judging the prognosis of patients with liver cirrhosis .

AIM: The aim of this investigation was to confirm the best operation conditions in the membrane separation of protein from the homogenate of red earthworm, Eisenia faefida. METHODS: Ultrafiltration membrane of fresh red earthworm with the cut-off of 10 000 was used as the target process, with the homogenate flux as index, the best value of operation parameters such as pressure、 temperature, surface rotation speed and feed concentration were fixed on. RESULTS: (1) The best suitable operation conditions were 0.25 MPa, 30?C , 200 r/min, pH=6.7, 33.3% (w:w) concentration and not a bit of NaCl. (2) The molecular weight distribution of protein in the homogenate of red earthworm mainly lay between 50 000～100 000. CONCLUSION: The obtained experimental results will provide pilot scale test with data support.

Objective To assess the efficacy and safety of emergency transcatheter arterial embolization in the management of intractable postpartum hemorrhage. Methods Twenty-five patients with intractable postpartum hemorrhage were undertaken superselective catheterization into the bilateral internal iliac arteries or uterial arteries to find the causes and sites of bleeding through DSA and then followed by arterial embolization with gelfoam particles. Result All of the 25 patients with obstetrical bleeding were successfully controlled by TAE, the procedure lasted for 25 - 60 min, (mean 42.5 ? 4.6 min); with both catheterization and bleeding halt successful rates of 100%. Comparison of hemoglobin and heartbeat before and after the procedure showed significance(t = 29.49, P

Objective To explore CT diagnostic values of cardiac carcinoma.Methods CT findings of cardiac cancer comfired pathologically in 50 cases were analysed.All case were examined with spiral CT.Results The thickness of gastric cardia wall was found in all 50 cases,soft tissue masses was found in 25 cases,adjacent tissue invasion was found in 18 cases and metastasis of lymph nodes was found in 33 cases.Conclusion CT is a valuable method in demonstrating the size of cardiac carcinoma,its adjacent tissue infiltration and lymph node metastasis.It plays important role in the planning of treatment in clinical practice.

Objective To evaluate the value of ultrasound-measured changes in diaphragmatic excursion (DE) in predicting successful weaning from mechanical ventilation during the spontaneous breathing trial (SBT).Methods Sixty-three patients of both sexes,who were mechanically ventilated for more than 24 h and screened for ascertained readiness to wean,aged 45-64 yr,were enrolled in the study.Bilateral DE was measured using ultrasound at 0,10 and 30 min of SBT.The patients who successfully completed 30 min of SBT were extubated.The patients were divided into either success group or failure group according to whether or not weaning was successful.Receiver operating characteristic (ROC) curves were used to evaluate the value of bilateral △DE30-10 in predicting successful weaning.Results There were 48 cases in success group and 15 cases in failure group.Bilateral △DE30-10 was significantly higher in failure group than in success group (P＜0.05).The area under the ROC curves of the right △DE30-10 in predicting successful weaning was 0.958,＜0.175 cm was used to predict successful weaning,and the sensitivity and specificity were 93.3％ and 87.5％,respectively.The area under the ROC curves of the left △DE30-10 in predicting successful weaning was 0.903,＜0.275 cm was used to predict successful weaning,and the sensitivity and specificity were 80.0％ and 89.6％,respectively.Conclusion The fight △DE30-10 measured using ultrasound can serve as an assistant index in predicting successful weaning from mechanical ventilation during SBT.
