Objective To explore the value of B-type natriuretic peptide (BNP) predicting cardiac events after noncardiac surgery in the aged patients. Methods The level of BNP, the score of Goldman analysis and the cardiac risk grade of ACC/AHA guideline were analyzed in 274 aged patients for cardiac outcome after noncardiac surgery. Results Preoperative BNP concentration>100 pg/ml,score of Goldman≥13,and the high or moderate risk grade by ACC/AHA guideline were related with cardiac events. There was no significant difference in the index such as sensitivity,specificity, accuracy,positive predictive value and negative predictive value for cardiac events between BNP level and cardiac risk grade. Compared with the score of Goldman, BNP was more sensitive (100% vs 55.6%)and negatively predictive (100% vs 96.3%) for cardiac events. Conclusion The risk of cardiac events after noncardiac surgery could be predicted with the level of BNP before operation in the aged patient.

OBJECTIVETo investigate the effect of a modified technique for repairing secondary defect of unilateral cleft lip.
METHODSThe incision line was designed along the oral-nasal contour line. The lateral crus of nasal alar were rotated and repositioned in order to reconstruct the nasal sill and base. V-Y plasty was performed with a muco-cartilage flap inside the nasal cavity to reset the alar cartilage backwards and correct the nasal deformity.
RESULTSSatisfactory results were achieved in all 69 patients with this modified technique. The post-operative scar was inconspicuous.
CONCLUSIONSThis modified technique with advantages of contour line incision and alar cartilage backward re-reposition is a good option for the repair of secondary defect of unilateral cleft lip.

OBJECTIVESTo observe the effects of pioglitazone on morphological changes and connective tissue growth factor (CTGF) expression of the transforming growth factor beta (TGF b)-induced rat hepatic stellate cells (HSCs) in vitro, and to investigate the anti-fibrotic mechanism of pioglitazone.
METHODSCultured rat HSCs were divided into a no-treatment control group, a TGF b-treated group, and a TGFb plus different dosage pioglitazone-treated group. The morphological changes of the cultured HSCs were observed. The expression of CTGF was assessed by immunohistochemistry and flow cytometry. The level of collagen type III in the culture supernatant was measured by ELISA.
RESULTSTGFb induced morphological changes, and increased the expressions of CTGF and collagen type III of the HSCs (P less than 0.05). Pioglitazone prevented the TGFb induced morphological changes of the HSCs. The expression of CTGF and the levels of collagen type III in the pioglitazone group were lower than the TGF b-treated group (P less than 0.05). This prevention effect was dose-dependent (P less than 0.05).
CONCLUSIONPioglitazone blocks the excretion of CTGF and collagen type III of cultured HSCs, preventing the development of liver fibrosis.

OBJECTIVETo analysis the efficacy and safety of lamivudine (made in China) therapy for 52 weeks in adolescent patients with chronic hepatitis B (CHB).
METHODSOne hundred and five teenage CHB patients were treated with lamivudine 100 mg once daily for 52 weeks. Patients with elevated ALT at baseline were in group 1 and those with normal ALT were in group 2. The changes of HBV DNA, HBV seromarkers and ALT at the end of 12, 24 and 52 weeks after lamivudine therapy were compared with those at baseline. Adverse events were recorded and evaluated.
RESULTSAt the end of 52 weeks of lamivudine therapy, HBV DNA-ve, HBeAg loss and anti-HBe seroconversion were observed in 92.0%, 24.4% and 22.0% in group 1 patients and 76.1%, 14.2% and 14.2% in group 2 patients respectively. No significant differences were found between two groups. At 12, 24 and 52 weeks, normalization rates of ALT were 59.0%, 66.7% and 76.0%, normal ALT with undetectable HBV DNA were 44.9%, 64.1% and 70.7% at the same time. During 52 weeks lamivudine treatment 26 mild adverse events were observed in 18 patients.
CONCLUSIONLamivudine can inhibit HBV replication rapidly and normalize ALT in majority adolescent CHB patients. HBeAg loss or seroconversion of anti-HBe was observed in some of these patients. All patients in this study were safety and well tolerated.

OBJECTIVETo explore the methods for repair of facial and cervical scars after burn.
METHODSOne hundred and two patients with facial and cervical scars as a result of burn injury were repaired by unilateral or bilateral deltopectoral flaps after expansion with pedicles. First, facial scars were excised and contractures were released to restore eye, mouth and nose to normal anatomical position. The facial scar flaps were overturned to join with the pedicles of deltopectoral flap for closing the wounds. The residual wounds were repaired by delayed flaps without pedicles 3 weeks later.
RESULTSAmong 102 patients, the flaps survived well in 94 cases, and blood supply insufficiency was found in distal end of unilateral flap in 7 cases (depigmentation after primary healing ). Necrosis of unilateral flap occurred in one patient, and it healed after skin grafting.
CONCLUSIONExpanded deltopectoral flap is efficacious procedure for repair of massive cervical and facial scars.

OBJECTIVETo investigate the efficacy and safety of diisopropylamine dichloroacetate in the treatment of nonalcoholic fatty liver diseases (NAFLD).
METHODSA randomized, double-blind, dose-paralleled control trial was carried out with NAFLD patients. The patients were randomly assigned to 2 groups treated with either a high dosage (120 mg/d) or a low dosage (60 mg/d) of diisopropylamine dichloroacetate for 8 weeks and the efficacy and safety of the drug were examined.
RESULTS127 cases were recruited for the trial, 63 in the high dosage group, and 64 in the low dosage group. No case dropped out in the trial but four cases were eliminated (4/127, 3.1%). The final number in this trial was 123, with 61 in the high dosage group and 62 in the low dosage group. After 8 weeks of treatment, the overall improvement of clinical symptoms in the high dosage and in the low dosage group was 87.8% and 79.6%, respectively. ALT normalization was found in 55.7% and 69.4% of the cases in the two groups, serum lipids were lowered in 67.2% and 67.7% and ultrasound grading of the liver alteration severity was lowered in 51.7% and 43.5% in the two groups. The differences found between the two groups were of no statistical significance. One case from each group was found having an adverse drug reaction of dryness of the mouth (1.6%). No severe adverse drug reactions were found.
CONCLUSIONDiisopropylamine dichloroacetate could be used as a safe and effective drug in the treatment of nonalcoholic fatty liver diseases.

OBJECTIVETo study the specific cellular immunoresponse of peripheral blood lymphocytes in the chronic hepatitis B patients treated with different doses of recombinant hepatitis B vaccine.
METHODSSeventy-two chronic hepatitis B patients who did not use any anti-HBV drugs within 6 months were randomized into 3 groups (90 micrograms, 60 micrograms, and placebo) in a ratio of 1:1:1. The patients in different groups were treated with different doses of recombinant hepatitis B vaccine in combination with IFN alpha 1b 50 micrograms with 3 times a week for 24 weeks. All patients were followed up for 24 weeks (W24). HBV DNA, HBeAg and liver functions were detected at different time points, and the number of cells that secrete IFN-gamma were detected by ELISPOT.
RESULTSThere were no significant difference in ELISPOT positive ratio among the 3 groups on baseline detection. At W24, 12 cases, 12 cases, and 7 cases showed ELISPOT positive in the group of 90 micrograms, 60 micrograms, and placebo. The proportion of patients who were ELISPOT positive was higher in the groups treated with recombinant hepatitis B vaccine (including the dose of 90 micrograms and 60 micrograms) than that in the placebo group (P=0.0446). HBV DNA turned negative in 6/24 of the patients treated with recombinant hepatitis B vaccine (at both the doses of 90 micrograms and 60 micrograms), and HBeAg/Anti-HBe seroconversion or HBeAg became negative in 7/24 of them. In the placebo group, none of the patients showed undetectable HBV DNA, HBeAg/Anti-HBe seroconversion or HBeAg disappearance. At the 24W of follow up, in the patients who were ELISPOT positive, HBV DNA became undetectable in 4 of the patients treated with recombinant hepatitis B vaccine (at doses of 90 micrograms and 60 micrograms), and HBeAg/Anti-HBe seroconversion or HBeAg disappearance were found in 9 of the cases. In the placebo group, none of the cases showed undetectable HBV DNA, and only 1 case had HBeAg/Anti-HBe seroconversion.
CONCLUSIONThe recombinant hepatitis B vaccine may increase the function of specific T lymphocytes in patients with chronic hepatitis B. There were no significant differences between the patients treated with the dose of 90 micrograms and 60 micrograms hepatitis B vaccine.
