Cavernous transformation of portal vein accounts for about 40％ in children portal hypertension.Compared with other causes of portal hypertension disease cavernous transformation of portal vein presents early age of disease onset,high risk of bleeding and normal liver function.Because the pathology is relatively simple and most children have no other diseases,so a reasonable treatment of the disease has decisive significance.The current concept for diagnosis and treatment of the disease is different between home and abroad,Controlling upper gastrointestinal bleeding is the main purpose in out country.Reliving hypersplenism,improving liver blood supply and quality of life are much important abroad,The article aims to summarize latest foreign literature to introduce latest research for the disease abroad.

Objective Galangin is a natural flavonoid with antineoplastic activity .SIRT1 is an important member of Sirtuin family which parcitipate in many physiological process .The aim of this study was to investigate the effect of SIRT 1 on HepG2 cell apop-tosis induced by galangin . Methods HepG2 cells were pre-treated with SIRT1 inhibitor EX-527 for 2 hours, and then galangin for 24 hours.DMSO solvent control group, EX-527 treatment group, galangin treatment group and EX-527 and galangin co-treatment group were established.Hoechst 33342 staining, flow cytometry and western blot were performed to detect the apoptosis of HepG2 cells.After regu-lating the expression of SIRT1 in HepG2 cells with RNA interference and transfection of exogenous genes , these cells were treated with ga-langin for 24 hours.Negative control group , vector control group , SIRT1 knock down group , blank control group , blank vector group ,and SIRT1 upregulation group were established .Western blot and Flow cytometry were performed to detect the apoptosis of HepG 2 cells. Results The apoptosis rate and the gray level ratio of shear band of PARP 1 and GAPDH that of galangin group [(11.62± 0.55) %, 0.89±0.01]and EX-527+galangin group[(25.75±0.61) %, 1.15±0.06] were all increased(P<0.01),when these were compared with DMSO solvent control group [(2.49±0.22) %, 0.06±0.00];and those in EX-527+galangin group were also markedly increased compared with galangin group (P<0.01).The result of western bolt was that the gray level ratio of PARP 1 and GAPDH of SIRT1 knocked down group(0.06±0.01) was markedly decreased compared with vector control group (1.11±0.05)and without adenovi-rus infection group (1.10±0.04)(P<0.01).The apoptosis rate and the gray level ratio of shear band of PARP 1 and GAPDH that of SIRT1 knocked down group were markedly increased compared with vector control group and without adenovirus infection group ( P<0.01).The gray level ratio of PARP1 and GAPDH of SIRT1 up-regulated group (1.63±0.04) was markedly increased compared with blank control group (0.89±0.02) and without plasmid transfection group (0.87±0.03) (P<0.01).The apoptosis rate and the gray lev-el ratio of shear band of PARP 1 and GAPDH that of SIRT1 up-regulated group were markedly decreased compared with blank control group and without plasmid transfection group (P<0.01). Conclusion SIRT1 inhibited galangin-induced apoptosis in HepG2 cells.

ObjectiveTo evaluate the efficacy of modified ultrafiltration (MUF) combined with conventional ultrafiltration (CUF) for cardiac valve replacement in patients with severe valve disease.MethodsOne hundred and eight NYHA Ⅲ or Ⅳ patients with severe valve disease,aged≥ 18 yr,weighing 50-80 kg,scheduled for elective cardiac valve replacement under cardiopulmonary bypass (CPB) were randomized into CUF group ( n =56) and CUF combined with MUF group (CMUF group,n =52).MUF was performed at the end of CPB,and the flow and time was 400 ml/min and 15-20 min respectively.Arterial blood samples were taken for blood gas analysis and for measurement of the plasma IL-6 and IL-8 concentrations after induction of anesthesia (T1),at the beginning of CUF (T2),at the end of GUF (T3),at the beginning of MUF (T4),at the end of MUF (T5),and at 2,8 and 24 h after the termination of CPB (T5-8).The oxygenation index was calculated and the airway pressure was recorded at T5 8.The amount of urine output during operation,the amount of urine output and volume of chest tube drainage within 24 h after operation,extubation time,packed red blood cell (PRBC) transfusion and duration of stay in ICU were recorded.ResultsCompared with CUF group,the hematocrit at T5,6 and oxygenation index at T7,8 were significantly increased,extuhation time was significantly shortened,and the amount of urine output and volume of chest tube drainage within 24 h after operation and PRBC transfusion were significantly reduced ( P ＜0.05),and no significant change was found in the plasma IL-6 and IL-8 concentrations,airway pressurc,amount of urine output during operation,and the duration of stay in ICU in group CMUF ( P ＞ 0.05).ConclusionCombination of MUF and CUF during CPB can be used for cardiac valve replacement in patients with severe valve disease,improve the function of organs after operation and reduce homologous blood transfusion.

Objective To investigate the effects of single and combined exposure to ozone and nitrogen dioxide on airway injury and inflammatory levels in mice. Methods Eighty BALB/C mice were randomly divided into eight groups:four were sensitized model groups(the control group,the O3 group,the NO2 group and the O3+NO2 group based on the way of exposure) ,the other four were non-sensitized groups. The concentration of O3 was 0.16 mg/m3,NO2 was 0.30 mg/m3. Mice were exposed 2 hours every day for 7 consecutive days. Mice were sacrificed in the exposure end and cell counting and cytokine measurement from bronchoalveolar lavage fluid(BALF) were performed. Results In the sensitized groups,neutrophil proportion and IL-6 were significantly increased except the control group and IL-2 and MDA were also significantly increased in the O3 group and the O3+NO2 group(P

Forty-seven patients with congenital heart disease and pulmonary hypertension were treated surgically. Among them, 31 were male and 16 female. The age ranged from 2 to 47(13. 7? 11. 2) years. Gongenital heart abnormalities included ventricular septal defect (VSD) in 20, huge atrial septal defect (ASD) in 1, VSD+ASI) in 12, VSD with patent ductus arteriosus (PDA) in 6, endocardial cushion in 2, VSD with aortopulmonary septal defect (APSD) in 1, double outlet right ventricle with PDA in 1 and total anomalous pulmonary venous connection in 1. Right heart catheterization was performed in 15 cases. The mean pulmonary artery pressure was (73 ? 24)mmHg, total pulmonary resistance was (78. 0 ?61. 2)kPa/(L/s). There were 7 cases examined in operation. Their mean pulmonary artery pressure was (55?13)mmHg. The others were examined by echocardiography. The mean pulmonary artery pressure was (49?15)mmHg. All patients were treated pre-op-eratively with oxygen inhalation therapy, hyperbaric oxygenation, prostaglandin E1 , respectively according to the degree of pulmonary hypertension. During cardiopulmonary bypass, pulmonary artery perfusion was performed with protective solution containing aprotinin for lung protection. Vasoactive drugs were routinely administrated postoperatively. There were 2 operative deaths with hospital mortality rate of 4. 3%. The cause of deaths was severe low cardiac output syndrome. The postoperative morbidity rate was 4. 3%. Our conclusion is proper peri-operative management could reduce post-operative mortality and morbidity for congenital heart disease with pulmonary hypertension.

Objective:To probe the effect of prenatal ethanol exposure on the mitochondrial protein expression in fetal mouse cerebrum. Methods:Pregnant CD-1 mice were given 5.0 g/kg ethanol intragastrically from pregnant days (PD) 6-15. Fetal cerebral mitochondria were isolated on PD 18. The overall mitochondrial protein was applied to two-dimensional gel electrophoresis. Differentially expressed protein spots were cut off and identified by matrix-assisted laser desorption ionization time-of-flight (MALDI-TOF) mass spectrometry. Activities of respiratory chain complex Ⅳ(72.3%?4.6% of control)and ATP synthase, and ATP content in the fetal cerebral cells were measured. Results:Expressions of some constructional and functional proteins were altered by in utero ethanol exposure. Activities of respiratory chain complex Ⅳ and ATP synthase (80.3%?5.1% of control)were both decreased. ATP content (67.9%?3.9% of control) in the cerebral cells was reduced in the in utero ethanol exposure fetuses. Conclusion:In utero ethanol exposure affects the mitochondrial protein expression of fetal mouse cerebrum, even in the tissue without obvious morphological malformations, which may be a possible mechanism of behavioral defects found in children with prenatal ethanol exposure.
