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 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.

OBJECTIVETo evaluate the operation time and clinical effect of three types of materials (i.e., total-etching adhesive, self-etching adhesive, resin-modified glass ionomer cement) that are used to bond removable thermoplastic appliances.

METHODSThirty malocclusion patients (156 attachments) with removable thermoplastic appliances were randomly divided into three groups, with 10 individuals each. Attachments of groups A and B were bonded using 3M Adper Single Bond 2 and 3M Adper Easy One, respectively; both adhesives utilized 3M Z350 nano composite resin. Attachments of group C was directly bonded using GC Fuji Ortho LC. The operation time of each attachment was recorded. Failure rates of adhesion were evaluated during adhesion, 1 month after treatment, and 6 months after treatment.

RESULTSThe operation time of group C was shorter than those of groups A and B (P<0.01). Significant difference of adhesion failure rates was not found among the three groups (P>0.05). No significant difference of adhesion failure rates was also observed in different times of the same group (P>0.05).

CONCLUSIONThe attachment stability of the three types of materials achieved satisfactory effects. However, the operation method of resin-modified glass ionomer cement is more concise and suitable for clinical promotion.

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 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.

Objective To evaluate donor remnant liver regeneration and influencing factors at different stages after right lobe adult living donor liver transplantation (LDLT) using multi-slice spiral computed tomography (MSCT).Methods 68 living donors were included in this study,We did CT volumetric measurement of the liver by using IQQA-Liver workstation.Liver regenerative ratio (LRR) at different stages of donors after LDLT were calculated and compared,correlation coefficient and stepwise regression analysis were calculated.Results The difference between LRRs at different stages after LDLT were significant (F =3.323,P =0.009),there were significant difference between LRR of 7-day and 1-month,3-month (respectively t =-2.065,-2.214,all P ＜ 0.05).The inclusion of middle hepatic vein and donor gender had no influence on LRR (respectively t =0.600,-0.622,1.464,0.926,-1.228,0.624,-0.688,0.131,all P ＞ 0.05).There were negative correlation between the remnant liver volume and LRRs (P ＜ 0.05).Conclusions MSCT is a valid modality to evaluate remnant liver regeneration after LDLT.Most evident remnant liver regeneration occurs in early stage after adult LDLT.
