Objective To observe the protective effect of different doses of left carnitine on cardiomyocyte function in children with viral myocarditis.Methods94 cases of children with viral myocarditis were selected and divided into observation group and control group according to the random number table, 47 cases in each group.Both groups were treated with fructose 1,6-diphosphate(100~250mg/kg, add 150mL of 10% glucose in intravenous infusion, 1times/d) combined with left carnitine.Large dose group of left carnitine 100 mg/kg, low dose group 50mg/kg, all added 150mL of 5% glucose intravenous infusion, 1 times/d.The total effective rate, creatine kinase(CK), creatine kinase isoenzyme (CK-MB),lactate dehydrogenase (LDH), cardiac ejection fraction(EF), ventricular short axis shortening (FS) And the total incidence of adverse reactions were compared between two groups.ResultsThe total effective rates of two group were 93.62% and 87.23%.The level of CK,CK-MB,LDH in two groups were significantly decreased after treatment of two weeks(P<0.05), EF, FS were increased after treatment of two weeks(P<0.05).There was no significant difference in CK, CK-MB, LDH, EF and FS between the high dose group and the low dose group after treatment of two weeks.The overall incidence of adverse reactions in the high dose group was 25.53%, which was lower than that in the low dose group (8.51%,P<0.05).ConclusionThe use of low-dose left carnitine in children with viral myocarditis can effectively remove free radicals, protect cardiomyocyte function and improve myocardial energy metabolism and cardiac function, and safer than high-dose groups.

ObjectiveTo evaluate the various methods of choledochoplasty in the repair of major bile duct defects in Mirizzi syndrome.MethodsThis is a retrospective study on 3 patient with Mirizzi syndrome with a large bile duct defect.These defects were repaired by using a vascular gastric pedicle patch in our department from July 2008 to November 2011.The authors searched the domestic medical literature on surgical repair for Mirizzi syndrome in the past ten years.The patients were treated by various surgical methods,and they were analyzed according to the Csendes Classification.ResultsThere were no surgical complications in our three patients.There was one patient with a Csendes type Ⅲ,while the remaining 2 patients were with Csendes type Ⅳ.At a median follow- up of 2.5 years,no patient developed signs of chronic cholangitis.In the medical literature,there were 93 patients who were with Csendes type Ⅰ ; and 58 patients were treated by cholecystectomy only,while 35 patients were treated by partial cholecystectomy plus mucosal ablation.Of the 40 patients with type Ⅱ,29 patients were treated by direct fistula repair,9 patients by pedicle gallbladder flap and 2 patients by pedicle round ligament.Of the 20 patients with type Ⅲ,9 patients were treated by pedicle gallbladder flap.1 patient by pedicle round ligament,3 patients by pedicle gastric flap and 7 patients by Rouxen- Y hepaticojejunostomy.For the 5 patients with type Ⅳ,they were treated by Roux-en- Y hepaticojejunostomy.Of these 159 patients,postoperative complications included biliary fistula (n=1 ),upper gastrointestinal bleeding (n=1),and biliary stricture (n=1).All the remaining patients were cured.ConclusionIn patients with Mirizzi Syndrome,the choice of treatment depends on the size of the fistula.For patient with a major tissue defect in the common hepatic duct,a pedicle vascular gastric flap is a good treatment.

AIM: To investigate the effect of T-bet plasmid gene transfer to airway on allergen induced airway inflammation in a murine asthmatic model. METHODS: A mouse asthma model was established by sensitization with ovalbumin (OVA). Forty C57BL/6 mice were divided into 4 groups (10 mice in each group): the normal control group (group A), the asthmatic model group (group B), the pcDNA3 plasmid group (group C), and the pcDNA3-T-bet group (group D). The animals in group B, C and D were sensitized and challenged with OVA. The animals in group A were applied with normal saline. pcDNA3 plasmid at dose of 50 μg was intranasally administered at 24 h before intranasal challenges to the mice in group C, and the 50 μg pcDNA3-T-bet plasmid for the mice in group D. Bronchial alveolar lavage fluid (BALF) was collected and lung tissues were resected at 48 h after OVA challenge for later assay. RESULTS: After administration with pcDNA3-T-bet plasmid, high level of T-bet expression at 48 h was detected in the lung tissue by Western blotting. In pcDNA3-T-bet treated asthmatic models, histological evaluation revealed the significant suppression of eosinophil peribronchial and perivascular infiltration, and reduction of epithelial damage. The numbers of eosinophils, neutrophils and lymphocytes in BALF from pcDNA3-T-bet treated mice were significantly reduced compared to those in asthmatic control group (P<0.05). The level of IL-4 in BALF was significantly decreased in pcDNA3-T-bet group compared to that in asthmatic control group (P<0.05), while the level of IFN-γ in BALF was significantly increased in pcDNA3-T-bet group. No significant change of inflammation cells and cytokines in pcDNA3 plasmid group and asthmatic control group was observed (P>0.05). CONCLUSION: Intranasal pcDNA3-T-bet plasmid transfer inhibits asthmatic airway inflammation in the murine asthmatic model, suggesting a new therapeutic strategy for allergic asthma.
