Some properties of ?-BT-HRP conjugates and its periodate method of preparaton were investigated.The results of SDS-PAGE, absorption spectrum, and the observations proved that the conjugates were heterogeneous, but stable ; the good conjugates had an O.D.403nm : O.D.280nm ratio(RZ) of approximately 1.0.The periodate method used in this study was reproducible. The conjugating effect between ?-BT and HRP was high.

The zymograms of esterase(Est)and lactic dehydrogenase (LDH) isozymes fromtwo species of Aedes were studied by polyacrylamide gel electrophoresis.The zy-mograms were divided into two groups of bands, Est Ⅰ and Ⅱ, and LDH ⅠandⅡ, respectively.They exhibited some similar characteristics of sibling species,On the basis of differences of Est Ⅱ phenotypes, the two species could be distinguished from each other

Objective To study the clinical features of patients with intracranial ependymal tumour, and explore the prognostic factors which have.a significant association with the outcome. Methods Eighty-three patients with histologically proven ependymal tumour were retrospectively reviewed. The tumour location, the patients' age, the histological features, imaging characteristics, surgical management and adjuvant therapy were studied. Results In 83 cases of intracranial ependymal tumour,41 cases were infratentorial and 42 cases were supratentorial ependymal tumour, 37 patients age ≤15 years, while 46patients age ＞ 15 years. Fifty-eight patients ( 69.9% ) and 25 patients (30.1% ) had low (WHO Ⅰ - Ⅱ ) and high-grade (WHOⅢ) tumors respectively. Sixty-reven (80.7%) patients had gross total resection and 16patients ( 19.3% ) had subtotal resection. The 5-year survival rate was 81.9%( 68/83 ). The factors that were found to have a statistical significance association with the outcome were the extent of the resection and the pathologic characteristics. Conclusions Gross total resection of these tumors results in a good long-term outcome. Reoperation should be considered, if feasible, to remove residual malignant tissue. Anaplastic ependymomas carries a much poorer prognosis. Radiotherapy may play an important role in their treatment.The role of chemotherapy appears limited but can be attempted, especially in the very young, in order to avoid the deleterious effect of radiotherapy.

In this paper, we studied the kinetics of nitochondrial lactate dehydrogenase (LDH) and solubilized mitochondrial LDH in the rat liver. The apparent Km values of mitochondrial LDH and solubilized mitochondrial LDH for substrate pyruvate were 50.0 ?mol/L and 33.8 ?mol/L, and those for NADH were 35.3?mol/L and 21.4 ?mol/L, respectively. The apparent Km values of mitochondrial LDH were greater than those of solubilized nitochondrial LDH. The mitochondrial LDH in the rat liver was mainly LDH-5, which could be solubilized by 0.15 mol/L NaQ solution.

In this paper, the effect of asolectin liposome on the activity of rabbit skeletal muscle lactate dehydrogenase (LDH) is reported. The results suggested that asolectin liposome could inhibit LDH activity, KC1 could restore the enzyme activity, and NAD+ and NADH could protect the enzyme from being inhibited by asolectin liposome.

Objective To study the effect of continous subcutaneous insulin infusion (CSII) and mutiple subcutaneous insulin infusion (MSII) on type 2 diabetes mellitus during perioperation. Methods One hundred and eighty surgical patients complicated with Type 2 diabetes were randomly divided into two groups,98 cases in the CSII group (treated with CSII of novolin R) and 82 cases in the MSII group (treated with MSII of novolin R and no-volin N). Blood glucose level,the time to reach normal blood glucose level, the average dosage of insulin, the inci-dence of hypoglycemic,infection rate of incisions and inpatient days were measured in two groups before and after treatment. Results The level of fasting blood glucose after treatment in the CSII group (4.8 mmol/L (SD: 1.6)) was significantly lower than that of the MSII group (6.4 mmol/L(SD :2.1)) (t = 7.74,P < 0.05), and 2-h glucose in the CSII group (7.6 mmol/L(SD :2.3)) was significantly lower than that of the MSII group (9.3 mmol/L(SD: 2.4)) (t = 7.72, P < 0.05). The time to reach normal blood glucose level in the CSII group (4.1 days (SD: 2.9)) was shorter than that of MSII group (6.9 days (SD :2.0)) (t=2.81, P < 0.05). The average dosage of insulin in the CSII group (40.7 U(SD: 10.3)) was lower than that of the MSII group (63.2 U (SD: 17.0)) (t=3.57, P <0.05). The incidence of hypoglycemic in the CSII group (3.05%) was lower than that of the MSII group (9.20%) (χ~2 = 4.92,P < 0.05). The infection rate of incisions in the CSII group (0.0%) was lower than that of the MSII group (10.9%) (χ~2 =4.18, P < 0.05). The inpatient days in the CSII group (15.3 days (SD :7.2)) was shorter than that of the MSII group (22.5 days (SD :9.7)) (t = 3.12, P < 0.05). Conclusions Compared to multiple sub-cutaneous insulin infusion, continuous subcutaneous insulin infusion is more effective in controlling blood glucose, hypoglycemic and incision infection, thus is recommend to perioperative patients complicated with type 2 diabetes mellitus.

A method by using ?-BT-HRP conjugate to localize N-acetylcholinc receptor of neuromuscular junction was described.Thin strips of fresh muscle were incubated with ?-BT-HRP conjugate at a concentration of 1?10-7 M in Tyroid's solution and then reacted with Karnovsky's DAB medium.There were obviously brownish red positive deposits to constitute various vesicular forms seen under a light microscope. Under an electron microscope we can see positive deposits that were localized both on the presynaptic and postsynaptic membra-nes. The binding activity and reliability of a-BT-HRP were discussed.

ObjectiveTo explore the effect of doctor-nurse integration mode in treating patients with liver cirrhosis treated with endoscopic variceal ligation (EVL).Methods According to the random number table,74 patients were randomly divided into control group and experiment group with 37 in each group.The control group was given routine nursing,while the experiment group was managed by doctor-nurse integration nursing mode.The two groups were compared in respect of early re-bleeding after EVL and mastery of health knowledge.Result The mastery of health-related knowledge in the experiment group was better than the control one and the rate of re-bleeding was significantly lower (P<0.05).Conclusion The doctor-nurse integration care mode can reduce the early postoperative re-bleeding after EVL in patients with liver cirrhosis and enhance the health education awareness.

Objective To study the predictive value of acute gastrointestinal injury (AGI) grading system introduced into Sequential Organ Failure Assessment (SOFA) score in patients with severe acute pancreatitis (SAP) in order to provide a reliable clinical tool for the evaluation of prognosis of SAP.Methods Patients with acute pancreatitis admitted to ICU from July 2012 to July 2014 were enrolled for study.The criteria of exclusion were the age below 18 years old,pregnancy,or patients without consent to the treatment.A total of 63 patients with 37 males and 26 females aged (47 ± 15.3) years were included.The data of their acute physiology and chronic health evaluation (APACHE) Ⅱ score,the highest SOFA score and AGI grade within the first week,and the 28-day mortality rate were collected.Patients without AGI were defined as zero point,and AGI grade Ⅰ-Ⅳ were defined as 1-4 points.The receiver operating characteristic curve (ROC) was used to evaluate the value of APACHE Ⅱ score,SOFA score,and SOFA + AGI score in predicting the prognosis of SAP.The areas under ROC curve (AUC) of the APACHE Ⅱ score,SOFA score,and SOFA + AGI score were compared with MedCalc software,and P value less than 0.01 was considered to be statistical significance.Results (1) The 28-day mortality of the 63 patients with SAP was 20.6％ (13/63),in which 50 patients in the survival group,13 patients in the death group.The APACHEⅡ scores of two groups were (15.62 ± 4.33 vs.12.10 ± 3.74,P=0.0048),the SOFA scores were (14.77 ± 3.09 vs.9.24 ± 2.88,P ＜0.01),and the SOFA + AGI scores were (18.77 ±3.09 vs.10.74 ± 3.17,P＜0.01).(2) The AUC of APACHEⅡ score was0.748 ± 0.084 (95％ CI:0.622-0.849),the AUC of SOFA score was 0.902 ± 0.059 (95％ CI:0.801-0.962),and the AUC of SOFA +AGI score was 0.963 ± 0.037 (95％ CI,0.882-0.994);There was no significant difference in AUC between APACHE Ⅱ score and SOFA score (P =0.10),and there was statistical significance between the AUC of APACHE Ⅱ score and that of SOFA + AGI score (P =0.013),and the difference in AUC between SOFA score and SOFA + AGI score was statistically significant (P =0.008).The Youden index and the positive likelihood ratio of SOFA + AGI score system were the greatest to be 0.863 and 15.38,respectively.Conclusions SOFA scoring system has better predictive value in patients with SAP when AGI grading system was introduced into it.

Objective To evaluate the effectiveness of robot-assisted training on lower extremities of patients with stroke. Methods PubMed, Medline, EMbase, Cochrane Central Register of Controlled Trials (CENTRAL), ISI Web of Knowledge, Ovid, China National Knowledge Infrastructure (CNKI), Wanfang Data and VIP Database for Chinese Technical Periodicals were searched for the randomized controlled trials (RCTs) about robot-assisted training for lower extremities of patients with stroke from the date of establishment to March 2013. The bibliographies of the retrieved studies were also searched. 2 independent researchers evaluated the included studies using the risk of bias provided by Cochrane Library. The extracted data were analyzed by RevMan 5.1 software. Results A total of 12 trials were discovered.Compared with conventional training, the robot-assisted training increased the score of Fugl-Meyer assessment (lower extremity)(WED=3.97, 95%CI: 2.84~5.10, Z=6.89, P<0.00001) and Berg Balance Scale (WED=3.13, 95%CI: 0.80~5.45, Z=2.63, P=0.008). However,the results of stride frequency (WED=8.40, 95%CI: -0.95~17.75, Z=1.76, P=0.08) and speed (WED=0.03, 95%CI: -0.02~0.07, Z=1.18, P=0.24) were not statistically significant. According to the Jadad Score of included studies, 4 of them were of low quality and 8 of them were of high quality. Conclusion The current evidence shows that to some extent, robot-assisted training could improve the lower extremities function.
