Objective To observe the inhibitory effect of pyridoxine hydrochloride (PN) combined with common chemotherapeutics on mice hepatoma cells H22 in vitro. Methods MTT assay was used to determine the effects of PN in combination with 10 different antineoplastic agents on H22 cells, and immuno-histochemistry was used to observe the distribution of PN in H22 cells and morphologic changes of the cells before and after PN treatment. Results After 24 hours incubation with 5 mmol/L PN, the treated cells expanded apparently with nucleus chipping. PN entered the tumor cell and was mainly condensed in cytoplasma and H22 cells were sensitive to PN. When administered concomitantly with chemotherapic agents, most of the combinations showed antagonistic effects while a few of the combinations were additive. For instance, doxorubicin (ADM) used in combination with PN inhibited cell proliferation with an IR value (IR=0.63) much lower than ADM alone (IR=0.71, P<0.01), and the CI value was less than 0.9, which indicated an antagonistic effect. However, PN in combination with ifosfamide (ICTX) showed additive effect (CI>0.9), and the IR value (IR=0.60) in combined group was higher than that (IR=0.40) in ICTX group (P<0.05). Conclusion PN treatment could increase the intracellular PLP level and result in growth inhibition and cell death, and combined administration of PN and ICTX might be a potential method to improve efficacy and to reduce toxic effects while a co-administration of PN and ADM should be avoided.

Objective To study on the value and safety of early endoscopic retrograde cholangiopan-creatography (ERCP)and endoscopic sphincterotomy (EST) in acute biliary pancreatitis. Methods Ninety-two patients with acute biliary pancreatitis underwent early ERCP (within 72 hours) and received endoscopic therapy (ERCP group). Another 40 patients with acute biliary pancreatitis were treated conservatively without ERCP (control group). The disappearance of abdominal pain, decrease of serum amylase level, the mean days and costs of hospitalization and complications were observed in all patients. Results In ERCP group, all patients were performed EST, stones in 72 choledocholithiasis patients had been removed with net-basket or air pocket. Ten cases of severe acute biliary pancreatitis received endoscopic pancreatic duct stents drainage. Ninety two cases of acute biliary pancreatitis received endoscopic nasal catheter bile drainage. The days of the disappearance of abdominal pain, the decrease of serum amylase levels, the cost of the hospitalization and the days of the hospitalization were significantly shorter in the early ERCP group than in the control group. The mortalities in ERCP and control group were 8. 3% and 33. 3% respectively. Conclusion Early ERCP endoscopic therapy is a safe procedure has the superiorities in lowering the mortality, hospital days and expense.

AIM: To compare the tumorigenecity of H22 cells transfected with TNF-? gene and its mutants (secreted TNF-? mutant, S-TNFm, transmembrane TNF-? mutant, TM-TNFm and wild type of TNF-?, Wt-TNF) in vivo . METHODS: Three kinds of mouse liver cancer cell line H22 expressing TNF-? and its two mutants were mixed with untransfected H22 at different effector/target ratio separately. The growth of tumor was examined after injection of 2.5?10 5 (100 ?L) mixed H22 tumor cells into mice. The lymphocyte infiltration in the site of tumor and the expression of Fas on tumor cells were detected by immunohistochemistry. RESULTS: The tumorigenecity of H22 cells transfected with TNF-? gene and its mutants was significantly weakened ( P

This study aims to develop a method for determination of beta-elemene, curcumol, germacrone and neocurdione in the volatile oil of Curcuma phaeocaulis, and to provide the basis of the quality control method for the volatile oil of C. phaeocaulis and the related preparations. Based on GC-MS, the 4 main compounds were simultaneously determined, with the internal standard n-tridecane. The Agilent 19091S-433 column (0.25 microm x 250 microm x 30 m) was adopted at the temperature of 250 degrees C, the programmed temperature method (60 degrees C for 1 min, 5 degrees C x min x to 110 degrees C for 5 min, 1 degrees C x min(-1) to 140 degrees C, 5 degrees C x min(-1) to 160 degrees C, 10 degrees C x min(-1) to 240 degrees C) was used. Helium gas was used as the carrier gas at a constant flow rat of 1 mL x min(-1), with an injection volume of 1 RL. Mass spectra were taken at 70 eV; the ion-source temperature was 200 degrees C. The relation time and character acteristic ions for each target compound were determined by full scan mode and SIM, and m/z 85.1, 93.1, 121.1, 107.1 and 180.1 were the detection ions of n-tridecane, beta-elemene, curcumol, germacrone and neocurdione. As a result, beta-elemene, curcumol, germacrone and neocurdione were all detected with good separation. They were all in a good linear relationship within each concentration scope. The average recovery rates were in the range of 98.2%-101%. So, the method can be used to control the quality of the volatile of C. phaeocaulis Val. and the preparations related.

Objective Introduce a technique for creating 3-dimensional (3D) brain models of subdural electrodes , ideal for demonstrating the space-relationship of seizure localization and eloquent cortices , and discuss its usefulness for presurgical evaluation of epileptic patients. Methods Patients with medically intractable epilepsy were underwent a thorough preoperative MR brain scan including a T1-weighted high-resolution 3D sequence. Intraoperative photographs were taken with the digital camera. After the surgical implantation of subdural electrodes for epileptic zone localization , the thin-slice CT scan of the electrodes were taken and coregistered to preoperative brain 3D MR images in the Medtronic StealthMerge software environment. After the iEEG monitoring , multiple habitual seizures were recorded , eloquent areas were also identified by electrical stimulation of the cortex. The epileptic zone and the eloquent areas were marked on the subdural electrodes respectively. Then, 3D tessellations of the epileptic zone and the eloquent areas were rendered. Results Six patients (4 male, 2 female) were enrolled in this study. The mean time of iEEG monitoring was 13.7 days. After the coregistration of postoperative CT with preoperative 3D MRI , the 3D stereoscopic reconstruction provided an accurate representation of the implanted electrodes with highly detailed visualization of the underlying anatomy. The visual comparison between 3D reconstructions and intraoperative photographs indicated a good correspondence. The patients were followed for 3 to 6 months after the secondary operation , and had continuing improvement in seizure control. Conclusions The results indicate that the 3D reconstruction of subdural electrodes can reveal the precise localization of subdural electrodes , and can be useful for the presurgical evaluation of epileptic patients.

Obiective:To elucidate the phenotype and the genotype-phenotype correlations in Chinese patients with X-linked adrenoleukodystrophy(X-ALD).Methods:Clinical features of 40 Chinese patients with X-ALD were studied and mutation spectrums were investigated by polymerase chain reaction (PCR) and sequencing. Results:Among these patients, four were siblings from two unrelated families, the others were unrelated. There were 31 cases with childhood cerebral (CCALD), 8 cases with adolescent cerebral (ACALD) and 1 case with adrenomyeloneuropathy (AMN). Visual impairment, which presented in 12 cases (30%), was the most common initial symptom. Nine (69%) of 13 cases who had hydrocortisone and ACTH measured showed adrenal insufficiency. By follow-up date, 19 cases (47.5%) were dead. The interval from onset to death varied from 1 to 6 years and the average were 3.3 years. The mean age at death was 10.5 years. Eleven cases (27.5%) were in vegetable state. The mean interval from onset to apparently vegetable state was 2.8 years (range from 1 to 6 years). Four cases had progressive neurological disability. Four cases were lost follow-up. One case with CCALD and one case with ACALD progressed slowly. The courses of the disease of these two patients were 5 years and 15 years respectively. Thirty five mutations were identified in 40 cases. Most were located within exon 1-3 (40%, 16/40) and exon 6-8 (42%, 17/40). There is a distinct clustering of missense mutations in exon 6 (17%, 7/40). Five types of mutations were associated with CCALD, three with ACALD and a missense mutation was identified in the patients with AMN. The two patients with long disease courses had a missence mutation c.1559 T>A and a nonsense mutation c.1785 G>A respectively. The siblings with similar manifestations and onset age were observed in two families, whose mutations were c.887 A>G and c.1028 G>T. Conclusion:The phenotypes, disease severity and rate of neurodegeneration could not be predicted by the nature of mutations.
