Objective To observe the clinical efficacy and safety of ultrapulse CO 2 laser-assisted au-tologous epidermal grafting for the treatment of vitiligo.Methods1605patients with30660skin grafts were treated by CO 2 laser-assisted autologous epidermal grafting.Among them,782patients had localized vi-tiligo,319segmental,226general and278scattered.Epidermal grafts were harvested with negative pressure blistering method from normally pigmented skin,and recipient areas were prepared with a ultrapulse CO 2 laser.The curative effect was evaluated8weeks later.Results79.04%of the lesions were cured complete-ly,and total response rate was92.21%,with better effect in localized and scattered lesions than in other le-sions.The best results were shown in face,while the worst results shown in brow and hairline lesions.Con-clusions The advantage of combined therapy of CO 2 laser with autologous epidermal grafting in vitiligo is of easy performance,convenience,high response rate,which is worthy of large scale application.

Objective To study the convenient, safe and effective surgical intervention methods for correcting prominent wide lower face. Methods According to the wideness of mandibular angles, single or combined surgical treatments were performed by an intraoral approach under nerve block and local infiltration anesthesia, such as grinding mandibular angles, curved osteotomy of the angles and osteotomy of ascending ramus outer layer, partial masseter muscle resection, partial buccal fat pad removal and liposuction of cheek to reconstruct the whole lower face contour. Resnlts In the 71 cases followed up for 4 to 24 months, 60 cases were excellent, 9 were acceptable and 2 were unsatisfactory. The total satisfactory rate was 97 %. Conclusion According to the characteristics of prominent wide lower face, single or combined surgical treatments are performed to reconstruct the bone and soft tissue of lower face. This operative method is simple, safe and consistent with cosmetic surgery principle with little complications.

Objective To explore the long-term efficacy of botulinum toxin type A injections on facial beauty and its long-term safety.Methods A total of 33 beauty-seekers with botulinum toxin type A treatment for more than five years were reviewed as observation group,using digital muscle palpation meter (Myoton PRO) for the determination of the orbicularis oculi muscle and masseter muscle tension (F),the muscle characteristic parameters,such as muscle hardness (S) using a homemade facial questionnaire test for satisfactory rate of beauty from both beauty-seekers and physicians.At sametime,33 normal adults that never accepted botulinum toxin injection with matched age and gender were collected as control group.The same-sex indicators were dtermined and compared with using statistic analysis t test.Results The pairwised parameters of the same sex and site were comparied between the two groups;average F and S values in the observation group were lower than those of the control group,but no statistically significant difference were observed between the two groups (P＞0.05);in the observation group,average appearance age was 7.3 years younger than the control group,and the facial shape improved significantly.Conclusions Long-term and repeated application of botulinum toxin A is able to remove crow's feet and decrease the masseter and so the injection is safe with high satisfaction to beauty-seekers.

Objective To investigate the dynamic changes of plasma myoglobin(Mb),troponinⅠ(TnⅠ) and brain natriuretic peptide(BNP)levels in the course of acute myocardial infrction(AMI)and to detect the best marker for early diagnosis and outcome prediction.Methods Plasma Mb,TnⅠand BNP levels were measured in 49 patients with AMI both before and after thrombolysis therapy and 32 controls.Results Plasma levels of all the three markers were significantly higher in the AMI patients than those in the controls(P

Objective To search for the changes of T cells subpopulations and immunoglobulin and their relation-ship in children patients with simple nephrotic syndrome. Design Case-control research. Patients aud Participants 39 patients with simple nephrotic syndrome were divided into two groups:the incipient group and relapse group (6 cases were determined at the incipient and relapse time) .Thereare 28 patients in incipient group, 19 males and 9 females, at the age of 2 to 10 years old. There are20 patients in relapse group, 12 males and 8 females, at the age of 3 to 13 years old. There are 35health children in control group, 21 males and 14 females, 2～13 years old. Interventions T cells subpopulations were determined by indirect immunofluorescence of OKT linesmonoclonal antibodies. The serum IgG was determined by routine simple agar immunodiffusion tests. Results and Conclusions The CD_3~+ and CD_4~+ cells are of no change in the children patients withsimple nephrotic syndrome, and the CD_8~+ and CD_(10)~+ cells are obviously increased, the Values of CD_4~+/CD_8~+ are obviously lower than those in the control qroup, there are no difference between the incipientand relapse groups. The levels of serum IgG were decreased in the 85.3% children patients, IgM were inc-reased in 29.4% of that. The values of CD_4~+/CD_8~+ have positive correlation and negative correlationwith the levels of serum IgG and IgM respectively.

Objective:To explore the efficacy and safety of amisulpiride at low dosage combined with clozapine in the treatment of refractory schizophrenia. Methods:Totally 160 patients with refractory schizophrenia were chosen from the psychiatric department of 4 hospitals during January to September in 2014 and randomly divided into the observation group and the control group with 80 cases in each. The patients were treated with clozapine plus amisupiride or clozapine plus placebo for 12 weeks. The positive and negative syn-drome scale ( PANSS) and treatment emergent side effect scale ( TESS) was used to respectively evaluate the efficacy and the adverse effects. Results:At the weekend of the 4th, 8th and 12th week after the treatment, the clinical efficacy in the observation group was sig-nificantly better than that in the control group (all P<0. 05). The total and every factors scores of PANSS after the treatment were sig-nificantly lower than those before the treatment in both groups ( P<0. 01), and the decrease in the observation group was more signifi-cant than that in the control group (P<0. 05 or P<0. 01). There was no significant difference in the incidence of adverse effects be-tween the two groups (P>0. 05). Conclusion:Amisulpiride at low dosage combined with clozapine can significantly improve the effi-cacy in the treatment of refractory schizophrenia without added adverse effects.

Objective To evalute the effect of Ilizarov technique in the treatment of hypertrophic nonunion.Methods Form June 2008 to December 2010,12 patients with hypertrophic nonunion were treated with Ilizarov technique,including 10 males and 2 females with an average age of 46.5 years.The pathology sites of nonunion were kept as closed as possible without any bone graft during operation.As to patients who had ever been treated with plate or intramedullary nail,the hardware should be removed by minimal invasive approach.These procedures aimed to keep the vascularity of nonunion site intact.Ilizarov apparatus were preoperatively constructed.Distal segment and proximal segment of nonunion were mounted respectively with two external circle using the smooth wires and half pins.The two-circle stabilizing one segment was nominated with transosseous modules.Distal module and proximal one was connected with a pair of axial hinges.The pathology sites were gradually distracted from the seventh day postoperatively,0.25 mm/d.Accompanying with deformity correction,limb length discrepancy (LLD) also were restored simultaneously.Then,all the screws and nuts in the apparatus should be tightened,which was favourable to the callus consolidation.Results All 12 cases of nonunion healed without any bone graft.The fixator wearing time lasted 6-12 months,with an average of 8 months.Correction of deformity and LLD were achieved.The average lengthening was 3.0 cm (range,2.0-5.5 cm),the average correction angle was 23° (range,10°-30°).After 6-18 months follow-up,all the patients restored satisfactory function.Conclusion Hypertrophic nonunion can be treated successfully with Ilizarov technique.The key of successful callus distraction is strictly identifying the indications.
