The effects of antisense oligonucleotides of c-fos and c-jun on the proliferation of CNE-2Z cells and on the expression of protein kinase C-? (PKC-?) were investigated. With the interpoising of Lipofectin(LP), the CNE-2Z cells were added with antisens oligonucleotides of c-fos and c-jun. MTT method was used to test the cell proliferation and flow cytometry (FCM) to the PKC-a expression. The results showed that the inhibition of antisense oligonucleotides of c-fos and c-jun to CEN-2Z cells was gradually enhanced with its concentration and prolonging time increasing and that its lowest effective concentration of LP was 1.7 X 10~(-6)?g/ml, the lowest effective concentration was of antisense oligonucleotides of c-fos and c-jun 1.7 x 10~(-5)?g/ml, and the most effective time was 20 hours after treatment. The fluoresence of PKC-a and percentage of positive cells in the groups treated by antisense oligonucleotides of c-fos and c-jun decreased significantly. The results indicated that the autisense oligonucleotides of c-fos and c-jun could inhibit the proliferation of CNE-2Z ceUs the expression of PKC-?.

Objective To evaluate the clinical features and prognosis of patients with complete left bundle branch block(CLBBB)following transcatheter device closure of ventricular septal defect(VSD)closure. Methods Clinical feathers of 11 patients with postoperative CLBBB in Department of Pediatric Cardiology,Guangdong General Hospital from January 2011 to December 2013 were collected and reviewed retrospectively. They were treated with dif-ferent protocol based on the appeared time of CLBBB occurrence and clinical symptoms. The patients were followed up, and the prognosis was recorded. Results The median age of 11 patients was 3. 9 years(3. 4 to 17. 5 years old). The median interval of intervention therapy to first attack of CLBBB was 2. 8 months(1 day to 25. 4 months). CLBBB oc-curred within 1 week to 1 month postoperatively in 4 patients,another 1 case suffered from CLBBB between 1 week to 1 month postoperatively,meanwhile 6 cases underwent CLBBB after 6 months postoperatively. The longest term of CLBBB attack postoperatively was 25. 4 months in 1 patient. The electrocardiograms on 5 patients returned to normal by only drug treatment. However,3 patients failed to recover with drug therapy,2 of them undertaken surgical procedure to re-move the occluder associated with VSD repair,1 patient recovered to normal and another converted to incomplete right bundle branch block. One of them refused to undertake surgical procedure and still bothered with persistent CLBBB. Another 3 cases did not receive special treatment due to the later attack of CLBBB(≥6 months)without clinical symp-toms. By the end of observation,the electrocardiogram(ECG)in 4 patients returned to normal,4 patients presented with persistent CLBBB. One patient's ECGs were presented with right bundle branch block. After ECG successfully returning to normal ECG by drug therapy,2 patients relapsed during follow - up,and 1 of them developed to an enlarging left ven-tricle and heart failure which led to death. Conclusions CLBBB may occur in short or long - term after VSD closure. ECG may become normal after early and appropriate treatment postoperatively. Systolic dyssynchrony and cardiac dys-function may be caused by persistent CLBBB. Therefore,patients with CLBBB after VSD closure should be treated ap-propriately without delay,and more frequent and longer follow - ups are required.

BACKGROUND: AG490 is a newly found JAK kinase inhibitor, which can compete with receptor tyrosine kinase for binding site to block JAK/STAT pathway, inhibit rejection-related cytokine activation such as interferon-gamma (IFN-γ) ultimately inhibiting rejection.OBJECTIVE: To evaluate the possibility and prospect of the AG490 as a potential immunosuppressor, explore its basic mechanism in comparison with Cyclosporine A (CsA).DESIGN, TIME AND SETTING: Comparative observation was performed at the Institute of Urinary Surgery, Fujian Union Hospital from October 2007 to April 2008.MATERIALS: AG490 was purchased from Sigma, USA.METHODS: Human peripheral blood lymphocyte (both T and B) were harvested from 8 healthy donors. Lymphocyte were isolated by density gradient method and cultured with phytohemagglutinin, interleukin-2 (IL-2) or mixed lymphocyte culture to induce human lymphocyte proliferation. MAIN OUTCOME MEASURES: ELISA was used to detect the concentration of IL-2, IFN-γ and IL-6 in different culture systems with the tyrphostin (AG490), CsA or FK506. RESULTS: IL-2 and IFN-γ in culture systems of phytohemagglutinin, IL-2 or mixed lymphocyte culture were inhibited by AG490 (P < 0.05), but IL-6 was not suppressed by AG490 (P < 0.05). This effect was similar to clinical CsA or FK506. CONCLUSION: AG490 may be a potential immunosuppressor.

ObjectiveTo study the efficacy of transcatheter arterial chemoembolization (TACE) combined with surgical resection in the treatment of ruptured hepatocellular carcinoma (HCC).MethodsThe clinical data of 26 patients who presented with ruptured HCC to our hospital from January 2008 to December 2011 were retrospectively studied. These patients received TACE (n=19),surgical resection (n=7),and surgical resection after TACE (n=8).ResultsShock in the 19 patients who received TACE was promptly corrected and the vital signs were stabilized.On subsequent CT,the tumors shrunk in size.Salvage liver resection was carried out in 8 patients 1 month after TACE.After treatment,AFP decreased or became normalized,thus the treatment results were good. A one-stage liver resection was carried out in 7 patients. One patient died after operation and peritoneal metastases occurred in 4 patients. Conclusions TACE stopped bleeding from ruptured HCC efficaciously,reduced the need for open exploration,and improved the rate of resection of HCC.TACE combined with surgical resection significantly lowered the rate of abdominal tumor metastases.

A method for determination of 6 plant growth regulators by high performance liquid chromatography-tandem mass spectrometry ( HPLC-MS/MS ) coupled with isotope-coded derivatization was developed. d0-10-Methyl-acridone-2-sulfonyl piperazine ( d0-MASPz, light form) and d3-10-methyl-acridone-2-sulfonyl piperazine ( d3-MASPz, heavy form ) were prepared as isotope-coded derivatization reagents for carboxyl compound. The carboxyl plant growth regulator standards and real samples were derivatized by d0-MASPz and d3-MASPz, respectively. The obtained solutions were mixed at a certain ratio, and then injected for HPLC-MS/MS analysis. The light and heavy derivatives were monitored with transitions of [M+H]+m/z 208. 2 and [M+H]+ m/z 211. 2,respectively. With heavy derivative as internal standard for corresponding light derivative, the global isotope internal standard quantification for 6 plant growth regulators was achieved. The results indicated that the proposed isotope-coded derivatization method could provide relative quantitative data with adequate linearity in a 10-fold dynamic range ( R=0 . 9991 ) . The detection and quantitation limits were 0. 19-0. 34 μmol/L and 0. 53-0. 96 μmol/L, respectively. The relative standard deviations were ≤3 . 8%, and the accuracies ranged from 97 . 5% to 103 . 8%.
