Objective To evaluate the effect of rediological intervention on thrombotic membranous obstructive Budd-Chiari syndrome(TMOB-CS) .Methods Seventeen cases of TMOB-CS were treated with mutliple stent inplantation to press the thrombus with PTA.Results The inferior vena cave(IVC) pressure declined from(29.4?3.13)cm H 2 O to (3.45?3.20)cm H 2 O after the multiple stent inplantation.There was no severe complication such as pulmonary thrombembolism occurrence in this series.All the patients had been followedup for 3 to 40 months and showed good results.Conclusion Multiple stent inplantation pressing the thrombus with PTA can be used to treat the patients with TMOB-CS.

Objective To build the method of computerized case classification,for the purpose of perfecting the diseases typing and classification,and supporting the management based on the quality and expenses of the disease.Methods 875 cases were defined into two types.Eight parameters were selected for non-surgery cases,namely the disease diagnosis,severity at admission,and age.For surgery cases,five parameters were defined,namely the disease diagnosis,operative quantity,and severity at admission.Then Fisher function was called into play to obtain the function descriminant equation,realizing computerized classification.Results The rate of matching was 86.2％ between computerized classification and manual classification.The high accuracy of function descriminant equation proves the satisfactory outcomes of the classification.Collusion The computerized classification is satisfactory in its outcomes,and therefore it can better quality of care and cost management of diseases in clinical practice.

Objective To explore the effect of application of continue performance test (CPT) in screening of attention deficit hyperactivity disorder( ADHD ). Methods Thirty-five children with ADHD and65 normal children had been applied with CPT and Conner questionnaire test. Used rank sum test to examine the outcome, established receiver operating characteristic (ROC) curve, analyzed the most valuable index among various data, formulated abnormal critical value, and carried on a consistency check between CPT screening outcome and clinical diagnosis outcome. Results Each CPT index of 35 children with ADHD was obviously higher than those of normal children(P＜ 0.05 ). Most indexes' area under the ROC curve exceeded 0.7, reactive time of VST was the highest among each index which achieved 0.915. It was high conformity between CPT screening outcome and clinical diagnosis outcome (Kappa = 0.935 ). Conclusion CPT can be applied in ADHD screening.

Object To study the microwave assisted procedure for the extraction of baicalin from root of Scutellariae baicalensis Georgi Methods An MSP 100D domestically made microwave sample preparation system with a maximum power of 850 watts was used. The effects of solvents, pressure/temperature of solvents and microwave radiation time on the yield of baicalin were studied by orthogonal experimental design. Results The optimal experimental conditions were extraction at 70% of microwave power with 30 times of 35% ethanol at a constant heating pressure/temperature of 0.15 MPa for 30 s. Conclusion The microwave assisted extraction not only takes a shorter time with better parallel results, but also gave an increased yield of about 10% as compared with ultrasonic extraction.

BACKGROUND:Craniotomy for severe traumatic brain injury is required to maintain the integrity of the dura mater. The artificial dura mater is now a common dural repair material, and looking for the ideal artificial dura mater is the exploring direction of neurosurgery.
OBJECTIVE:To explore the application of colagen sponge artificial dura in severe traumatic brain injury
METHODS:A retrospective analysis of 96 patients with severe head injury was performed, including 32 cases of the artificial dura with tightly suturing as the control group, and 64 cases of the artificial dura of colagen sponge without suturing as the experimental group. Operating time for hematoma clearance, blood loss, postoperative mechanical ventilation time, ICU monitoring time, the total number of hospitalized days as wel as time interval from hematoma clearance to cranioplasty, operative time for cranioplasty, blood loss, and Glasgow Coma Scale scores after dural damage and 6 months postoperatively in the two groups were measured.
RESULTS AND CONCLUSION:The same purpose was achieved in the two groups. The amount of bleeding during hematoma clearance, postoperative mechanical ventilation time, monitoring time in ICU, the total number of hospitalized days and Glasgow Coma Scale score of 6 months postoperatively showed no significant difference between the two groups (P> 0.05). But operative time for hematoma clearance and cranioplasty as wel as blood loss in the second operation were statisticaly significant between two groups (P< 0.05). The colagen sponge artificial dura in severe traumatic brain injury can fuly play a good role in reducing intracranial pressure, keeping brain functions, shortening operative time, and improving outcomes of patients, which has similar effects to tightly suturing the dura and creates favorable conditions for the folowing cranioplasty.

Objective To evaluate the utility of modified Z-stent in treatment for Budd-Chiarisyndrome (BCS). Methods A retrospective study was used in twelve BCS patients treated in twohospitals. The Doppler examination was carried out in all patients preoperatively, so as to confirm thenature of the lesion and chose correct type of endovascular modified Z-stent. Under DSA monitoring formembranotomy and dilation of the inferior vena cava(IVC), after that, insert the marked modified Z-stent to IVC correctly, and put the non-stent part to hepatic vein orifice. The cavography and hepaticvenography should confirm the position of the Z-stent. All of 12 patients with membranous obstructionof the IVC(MOVC) or segmental obstruction of the IVC (SOVC)were underwent modified Z-stentplacement. Results The IVC pressure (IVCP) before smd after membranotomy (dilation) were 27.33± 4.12cmH2O and 18.67 ± 5.07cmH2O (P＜0.01). Comparing with dilation and putting stent group,the IVCP decreased from 18.67 ± 5.07cmH2O to 11.42 ± 2.11 cmH2O ( P ＜ 0.01 ). The modffied Z-stent could avoid hepatic vein orifice getting compression and resist the retraction of IVC throughly infollowing-up period of 2.5 years. Conclusion s The endovascular treatment of BCS with modified Z-stent is more effective and safer to prevent thrombosis. Further study will be required to observe theirlong term effects.

4-Hydroxybutyric acid (4HB) is a psychotropic drug used for polymer synthesis such as poly (4-hydroxybutyric acid) (P4HB) and poly (3-hydroxybutyric acid-co-4-hydroxybutyric acid) (P3HB-co-4HB). 1,4-butanediol (BD) can be converted to 4-hydroxybutyric acid by alcohol dehydrogenase (DhaT) and aldehyde dehydrogenase (AldD). In this study, high efficiency promoters including T7 promoter and P(Re) promoter were cloned to increase expression of dhaT and aldD, and thus accelerate the conversion from BD to 4HB. A. hydrophila 4AK4 (pZQ01), the recombinant strain under the control of T7 promoter, produced 6.00 g/L 4HB from 10 g/L BD with the productivity increased by 43.20%. While A. hydrophila 4AK4 (pZQ04), the strain under the control of T7 promoter, produced 4.87 g/L 4HB from 10 g/L BD, and the productivity was increased by 16.23%. Thus, the gene expression was increased by T7 and P(Re) promoters, leading to an accelerated biosynthesis of 4HB.

This study aims to investigate the change of plasma concentration of digoxin (DIG) in rats with ovariectomy. Twelve female SD rats were randomly assigned into ovariectomized group and sham group (n = 6). All rats plasma was collected after a single dose of 2 mg x kg(-1) DIG administrated orally, serum DIG concentration was determined by LC-MS/MS. The level of P-gp in the intestinal was analyzed by Western blotting. Pharmacokinetic calculations were performed on each individual using DAS 2.0 practical pharmacokinetic software. Compared with the sham group, C(max) of ovariectomized group decreased significantly (P < 0.01). There was no significant difference of AUC(0-t), and the level of P-gp was elevated in ovariectomized group. It was found that C(max) of DIG was significantly reduced after ovariectomy, and the change was associated with the decreased level of estrogen, which contributes to the increased level of P-gp.
