Objective To discuss the surgical treatment for huge hepatoblastoma in children,and the technique of hepatectomy without blockade of the blood supply to the remained liver lobes.Methods We reviewed 12 cases of huge hepatoblastorna who had been operated from July 2001 to January 2009 in our hospital.The mean age of the children was 3.2 years(range,11 months to 12 years).The diameter of the tumor was from 10 to 23 cm.3～7 cycles of chemotherapy was routinely administrated before operation.When the tumor reduced to a certain size that radical resection could be performed safely,regular hepatectomy was conducted.Hepatoblastoma resection without blocking the blood supply to the remained liver lobes was performed in every patient.Results The operations were successfully accomplished in all the 12 children.5 cases received right trihepatectomy (segment Ⅳ,Ⅴ～Ⅷ),4 cases received right hemihepatectomy(segment Ⅴ～Ⅷ),and the other 3 cases received Ⅳ,Ⅶ,Ⅷ segmentectomy,right Ⅴ,Ⅵ segmentectomy,and left hemihepatectomy respectively.The intraoperative hemodynamic parameters were stable,and there was no perioperative mortality.Postoperative chemotherapy wag routinely administrated.The follow-up period varied from 2 to 92 months.11 children survived and were disease free,among those 6 children have survived for more than 5 years.One child had brain and lung metastasis 5 months post operation,and died 7 months post operation. Conclusion Preoperative chemotherapy administrated to children with huge hepatoblastoma can reduce the tumor size and render tumor reseetable.Hepatoblastoma resection without blocking the blood supply to the remained liver lobes is a safe and feasible surgical technique.

OBJECTIVETo evaluate the clinical effect of removing dampness and purgative (RDP) method in treating acute, subacute and chronic severe hepatitis.

METHODSOne hundred and twenty cases of severe hepatitis were randomly assigned to 2 groups, 60 patients in the control group were treated with routine Western medicine, 60 patients in the treatment group were treated with the same Western medicine plus Chinese medicine prescribed based on RDP principle orally and/or via enema. Fourteen days of treatment constituted one therapeutic course, and patients were treated for 3 courses. Changes of clinical symptoms and signs, complication occurrence, liver function, serum markers of hepatitis B virus, and some biological indexes were observed and compared. The case fatality rate was compared after a 6-month follow-up.

RESULTSThe total effective rate and marked improving rate in the treatment group was 71.7% (43/60 cases) and 48.3% (29/60 cases) respectively, while those in the control group, 51.7% (31/60 cases) and 20.0% (12/60 cases) respectively, showing significant difference between the two groups (P < 0.05). After treatment, the clinical symptoms and signs were relieved and complications were reduced in the treatment group, showing marked improvement as compared with that in the control group (P < 0.05). ALT, AST, TBil, quantitative titer of HBV-DNA and HBeAg decreased markedly, and ALB, prothrom-base activity (PTA) and total cholesterol (TC) increased significantly in both groups after treatment (P < 0.01). Significant difference was found in AST, TBil, PTA and quantitative titer of HBV-DNA between the two groups (P < 0.05, P < 0.01). In the 6-month follow-up, the case fatality rate was 23.3% (14/60 cases) in the treatment group, significantly lower than that in the control group (P < 0.05), which was 41.6% (25/60 case)

CONCLUSIONRDP treatment is helpful to improve the prognosis of patients with severe hepatitis, it is one of the effective measures for enhancing the efficacy of comprehensive treatment.

To evaluate the role of murine fibrinogen like protein 2 (mfgl2) /fibroleukin in lung impairment in Severe acute respiratory syndrome (SARS), a murine SARS model induced by Murine hepatitis virus strain 3 (MHV-3) through trachea was established. Impressively, all the animals developed interstitial pneumonia with extensive hyaline membranes formation within alveoli, and presence of micro-vascular thrombosis in the pulmonary vessels. MHV-3 nucleocapsid gene transcripts were identified in multiple organs including lungs, spleen etc. As a representative proinflammatory gene, mfgl2 prothrombinase expression was evident in terminal and respiratory bronchioles, alveolar epithelia and infiltrated cells in the lungs associated with fibrin deposition and micro-vascular thrombosis. In summary, the established murine SARS model could mimic the pathologic characteristics of lungs in patients with SARS. Besides the physical damages due to virus replication in organs, the up-regulation of novel gene mfgl2 in lungs may play a vital role in the development of SARS associated lung damage.

Four triterpenoids were isolated and purified from the 95% ethanol extract of Maytenus guangxiensis by silica gel column chromatography, Sephadex LH-20 column chromatography, MCI column chromatography and preparative RP-HPLC. Their structures were determined from their physicochemical properties and spectral data. They were identified as maytguanone A (1), maytguanone B (2), 11α-methoxyurs-12-ene-1β,3β-diol (3), lup-20(29)-ene-3β,11α-diol (4). Compounds 1 and 2 are new triterpenoids, along with compounds 3 and 4 were isolated from M. guangxiensis for the first time. The cytotoxicity of compounds 1, 3 and 4 was evaluated using the MTT procedure with three cancer cell lines. The results show that compound 3 displayed good inhibitory effects against HeLa, with an IC₅₀ of 10.68 μmol·L^-1.

BACKGROUNDAlthough video-assisted radical operation for lung cancer has been widely accepted for treatment of nonsmall cell lung cancer (NSCLC), the debate over video-assisted thoracic surgery (VATS) segmentectomy still remains. This study analyzed the clinical outcomes using VATS segmentectomy for stage I NSCLC patients to explore the safety and efficacy of VATS segmentectomy for Ia NSCLC.

METHODSRetrospective review was conducted of patients who underwent VATS segmentectomy for clinical stage I NSCLC at Shanghai Chest Hospital between November 2009 and May 2012. VATS segmentectomy was performed on 36 patients. Analyses of the patient group were performed on patient demographics and clinical characteristics, intraoperative parameters, complications, and postoperative survival.

RESULTSThirty-five of thirty-six patients underwent VATS segmentectomy with only one conversion to open thoracic surgery. There was one peri-operative mortality from the segmentectomy group and all other patients are alive with a median follow up of 327 days. The mean volume of chest tube drainage after operation for segmentectomy was 1021.4 ml. Among other parameters, the mean blood loss was 162.5 ml (50.0 - 1600.0 ml), the mean operation time 124.8 minutes (75.0 - 271.0 minutes), chest tube duration 4.1 days (2 - 8 days), and the mean length of hospital stay 6.2 days (4 - 11 days). There was one (2.8%) locoregional recurrence after segmentectomy. Two patients successfully underwent bilateral segmentectomies and are still disease free.

CONCLUSIONFor patients with stage I NSCLC, VATS segmentectomy offers a safe and equally effective option and can be applied to complicated operations such as bilateral segmentectomy.
