Objective To quantitatively evaluate the efficacy of radiofrequency technology in the facial rejuvenation. Methods Six Chinese female volunteers received five times treatments at 4 days interval with the Slimager radiofrequency device on one side of their face, the other side as a control. After that, we evaluated the clinical efficacy by patients, clinicians, and professional measuring Angel Software, respectively. Results The results showed that the skin looseness and rhytides improved significantly after treatment (20 days). Patients and doctors were satisfied with the efficacy. Data measurements showed that the face levitated by 2.4 mm, the nasolabial fold levitated by 2.2 mm after the treatment. Conclusions The radiofrequency technology is a safe, non-invasive and non-surgical treatment method, which is effective for tightening skin, eliminating rhytides, and rejuvenating face.

Objective To study the effect of danshao shugan granule combined with metformin in treatment of nonalcoholic fatty liver and its effects on lipid and uric acid metabolism.Methods 80 patients of nonalcoholic fatty liver who received therapy from February 2014 to February 2015 in our hospital were selected as research objects.According to random number table,those patients were divided into the observation group (n=40) cases in each group and the control group (n=40).The control group was treated with metformin, while the observation group was treated with danshao shugan granule combined with metformin.Then blood lipid level, FBG, FINS, IR, SUA level, SOD, MDA level, therapeutic effect of two groups after treatment were compared.Results After treatment, TG,TC in observation group was significantly less than the control group (P<0.05); FBG, FINS, IR, SUA levels in the observation group were significantly lower than the control group ( P<0.05 ); SOD level higher than the control group, MDA level significantly less than the control group (P<0.05); The total effective rate of observation group was statistically higher than that in the control group (P<0.05).Conclusion Danshao shugan granule combined with metformin is well for nonalcoholic fatty liver,which can improve the glucose, lipid, uric acid metabolism and insulin resistance, and can protect the liver function.

Objective To evaluate the efficiency and preliminary results of transcatheter closure of perimembrane ventricular septal defects (PMVSD) using Amplartzer occluder device in children.Methods There were 5 children using transthoracic echocardiography(TTE) to confirm the PMVSD before the intervention. The diameters of the PMVSD were measured by angiography; Each of the children were treated with Amplartzer occluder device for transcatheter closure of PMVSD under TTE and fluoroscopy. The TTE and elec-trocardiograph(ECG)、chest X-ray were performed 24 hours,1 and 3、6 months after the procedure to evaluate the therapeutic effect. Results The mean diameter of the PMVSDs measured by angiography was 5.0?2.4 mm(Ranging from 2.5 to 8.3 mm). The mean diameter of the occluder selected was 7.4?3.2 mm(Ranging from 4 to 10 mm). The success rate was 100%, and no complication occurred during the procedure. No residual shunts were found by angiography immediately after the procedure in all cases. There were no malpositions of occluder and no residual shunts in the 5 cases by TTE after the procedure 24 hours , 1 and 3、 6 months. There were no cardiac arrhythmia found by ECG. It showed that both pulmonary vascularity were improved.Conclusions Transcatheter closure of perimembrane ventricular septal defects using Amplartzer occluder device is an efficient therapy for children with PMVSD. The operation is simple with a high success rate of placement and a good occlusion effect. Further studies of long term results are required.

Objective To evaluate graft regeneration and influencing factors after right lobe adult living donor liver transplantation (LDLT) using MSCT.Method Sixty-three living recipients were included in this study.We measured graft volume periodically by using MSCT and IQQA-Liver workstation.The liver regenerative ratio (LRR) of different stages of recipients after LDLT was calculated and compared,and stepwise regression analysis was done to set up the regression equation.Result Within 0.5 month after LDLT,graft volume was increased rapidly,and LRR reached maximum [(106.11 + 30.90)％],then decreased slowly.There was significant difference in LRR among 0.5,1 month and 3,6 months after LDLT (P＜0.05).The following factors,including whether the graft containing middle hepatic vein or not,age and sex of recipients,had no significant influence on LRR after LDLT (P＞0.05).The status of liver function of recipients preoperatively had significant influence on LRR 0.5 month after LDLT (P＜0.05).There was significantly negative correlation between the graft volume and LRRs of recipients at different stages after LDLT (P ＜ 0.05).Regression equation could be derived.Conclusion Most evident graft regeneration occurs in early stage after adult LDLT.There are many and different factors influencing graft regeneration at the different stages after LDLT.Graft volumetric measurement by using MSCT is a valid modality to evaluate graft regeneration after LDLT.

Objective There is no enzyme multiplied immunoassay technique ( EMIT) reagent for therapeutic drug monito-ring ( TDM) in our country.The aim of this study was to compare the properties of self-developed kits and commercially imported kits in TDM, and to evaluate their feasibilities for routine TDM. Methods The sensitivities, accuracies and precisions of self-developed kits, Viva-E kit and AXSYM kits were evaluated by determining the quality control samples of carbamazepine, valproic acid and phe-nobarbital.Self-developed kits, Viva-E kit and AXSYM kits were employed to determine the concentrations of clinical serum samples of 83 cases of carbamazepine, 80 cases of valproic acid and 72 cases of phenobarbital separately, and the results were compared and analyzed. Results Recoveries of carbamazepine, valproic acid and phenobarbital were more than 90% for the three different kits. The recoveries of self-developed kits for the three drugs were in the range of 98.7%-103.9% and the limits of quantification of the self-developed kits for carbamazepine, valproic acid and phenobarbital were 2, 10, 5μg/mL, respectively.Precision was lower than 10%and its average relative deviation was less than 3%after single point correction.There were good correlations (R2>0.985) and no significant statistical difference between self-developed kits and AXSYM kits (P>0.05).Upper and lower 95%limits of agreement in Bland-Altman plots were (-1.32,1.26), (-15.24,15.17) and ( -3.69,3.00) for carbamazepine, valproic acid and phenobar-bital, respectively.About 5%of the points failed in the 95%confidence interval. Conclusion The self-developed kits showed good performance and are suitable for clinical use in TDM.

AIM: To observe the effects of carvedilol on murine viral myocarditis model. METHODS: A total of 188 inbred male BALB/c mice of 4-6 weeks were divided into 4 groups: myocarditis group (group C, n=60), metoprolol treatment group (group M, n=60), carvedilol treatment group (group K, n=60), control group (group B, n=8). Myocardial histopathololgic changes were observed. The concentrations of cardiac troponin I (cTn-I) were detected by chemiluminescence immunoassay (CLIA). Western blotting was performed to analyze the contents of phosphorylated p38MAPK in myocardium. RESULTS: Metropolol and carvedilol lightened myocardial histopathololgic changes at acute stage, decreased cTn-I concentrations and myocardial phosphorylated p38MAPK value compared with myocarditis group. Treatment with carvedilol was more effective than treated with metropolol on those indexes. CONCLUSION: Carvedilol protects against viral myocarditis by inhibition of p38MAPK signal transduction pathway through blockade of β_1 and β_2 adrenergic receptors.

Objective To evaluate the impact of donor age on graft short-term outcome after right lobe adult living donor liver transplantation (LDLT).Method Thirty living recipients were divided into 2 groups according to donor age:older donor group (O group,donor age ＞50,n =5) and younger donor group (Y group,donor age ＜30,n =25).Alanine transarninase (ALT),aspartate transaminase (AST),total bilirubin (TB),prothrombin time (PT) on the postoperative day 1 to 5 and graft liver regenerative ratio (LRR) on the postoperative month 0.5,1,3,and 6 between 2 groups were determined and compared.Result TB on postoperative day 1,2,3,4 and 5 was significantly higher in O group than in Y group there were significant differences between two groups (P＜0.01).There was no significant difference of other liver function parameters 2 groups (P ＞ 0.05).There was no significant difference in LRRs on the postoperative month 0.5,1,3 and 6 months postoperatively between 2 groups after LDLT (P＞0.05).Conclusion Although allografts from older donors in LDLT have prolonged jaundice than those of their younger counterparts,after strictly preoperative evaluation,donor age has little effect on short-term outcomes of graft after LDLT.

Objective To evaluate the impact of donor age on early remnant liver function and regeneration after right lobe adult living donor liver transplantation (LDLT) donation.Methods 43 living donors were divided into 2 groups:donor age ＞ 50,n =8,and donor age ＜ 30,n =35.Alanine aminotransferase (ALT),aspartate aminotransferase (AST),total bilirubin (TB) and liver regenerative ratio (LRR) of donors between the 2 groups were compared.Results There were no significantly different in ALT,AST and TB on days 1,2,3,5 after LDLT between the 2 groups (respectively t =0.147,1.030,-0.903,0.013,0.043,1.362,0.817,0.003,1.121,0.241,1.061 and 0.943,all P＞0.05).There was significant difference between LRR on day 7 (t =-0.965,P =0.042),but the difference was not statistically significant in LRR when evaluated on day 15 after LDLT (t =0.585,P =0.385).Conclusions Remnant liver regeneration on the first week is reversely affected by donor's age after hepatectomy,while the influence of age decreases significantly after 2 weeks.

Objective To evaluate and compare liver regeneration between normal donors and recipients at the different stages after right lobe adult living donor liver transplantation (LDLT) using MSCT.Method Sixty-eight living donors and 63 recipients without complications were included in this study.We did CT volumetric measurement of the liver by using IQQA-Liver workstation.The relationship between graft volume measured by preoperative MSCT and intraoperative actual graft volume was evaluated.The liver regenerative ratio at different stages of donors and recipients after LDLT was calculated and compared.Result Preoperative measurement of total liver and grafts resulted in a mean volume of (1366.99 ± 234.75) cm3 (standard deviation) and (862.73 175.94) cm3 (VCT-right),respectively.Intraoperative volume of the grafts was (654.46 ± 151.23) ml (Vintraop).Corresponding pre-and intraoperative data were correlated significantly each other (r =0.795,P=0.000).Vintraop can be calculated with the equation:Vintraop =64.949 + 0.683 VCT-right.There was significantly difference in LRR between donors and recipients at 0.5,1,3 and 6 months after LDLT (P＜ 0.05).Conclusion The patterns of normal liver regeneration between donors and recipients after LDLT are different.The liver of donors regenerates more significantly and quickly than recipients.Liver volumetric measurement by using MSCT is a valid modality to evaluate liver regeneration after LDLT.
