[Objective]To evaluate the factors causing loosening of instrumentation and the progressive deformities after treating thoracolumbar bemivertebra with segmental instrumentation,and analyze the outcomes and strategies of reversion.[Method]A retrospective study was made in 7 cases with loosening of instrumentation and the progressive deformities secondary to operation on thoracolumbar hemivertebra in our hospital.There were 3 males and 4 females,with age range of 1.8~13 years.Preoperative mean Cobb's angles of scoliosis was 34.1?,and kyphosis was 40.2?.All cases were treated with posterior reversion.[Result]The failure factors of primary surgery were resulted from:failure of single hemivertebra resection(4 cases),shortage of segments fixation and bone graft(5 cases),unsatisfactory selection of instrumentation(2 cases),failure of manipulation in young children(2 cases),segment fixation without fusion(1 case).Postoperative mean Cobb's angle of scoliosis was 12.6?,with correction rate of 63.0%,and kyphosis was 17.3?,with correction rate of 56.9%.The revision cases were followed up for 18 to 28 months and showed that all patients got satisfactory cosmetic correction and fine fusion.No neurological complication or infection occurred,no implant failure were verified at the final radiographic evaluation.[Conclusion]The reasons for postoperative loosening of instrumentation and the progressive deformities includs:free from hemivertebrectomy,inappropriate segments fixation and bone graft,unsatisfactory selection of instrumentation,impropermanipulation in young children,fixation without fusion.If the above-mentioned five reasons of reversion strategies have been considered and avoided,the clinical results will be satisfactory.

Objective To investigate the cause and development of atrioventricular block (AVB) occurred during and after transcatheter closure of ventricular septal defect (VSD), and to explore its feasible prevention and treatment. Methods From Mar, 2005 to Dec, 2005, 157 patients who suffered from congenital VSD underwent transcatheter interventional occlusion. Transient Ⅲ degree AVB occurred in 2 patients during the transcatheter therapy and Ⅱ degree AVB in 2 patients and Ⅲ degree AVB in 3 patients were observed 4 hours to 8 days after the therapy. Two of them suffered from Adams-Stokes syndrome. All patients were treated by intravenous injection of glucocorticosteroid, diuretic and dehydrator. One of them was also treated with temporary pacing. Results AVB did not re-occurred after the transcatheter closure in 2 patients who suffered from transient Ⅲ degree AVB during the transcatheter interventional therapy. The cardiac rhythm in 3 patients who suffered from Ⅲ degree AVB after the transcatheter closure reverted to sinus rhythm in 7, 8 and 18 days after the operation respectively. However, 2 of them suffered recurrent Ⅲ degree AVB after discharge, and one of them could not be restored to sinus rhythm. Three patients who suffered from the Ⅱ degree AVB resumed to sinus rhythm in 5, 7 and 8 days after the transcatheter closure respectively, and the type Ⅰ and the type Ⅱ of Ⅱ degree AVB alternated before the rhythm completely reverted. Conclusion AVB is a frequent complication during and after transcatheter closure of VSD. AVB occurred after transcatheter occlusion should be treated actively, or it may become permanent AVB. Improving the cardiac transcatheter interventional device and technique can prevent the high degree AVB in certain degree.

OBJECTIVE:To investigate the study of traditional Chinese medicine (TCM) in the treatment of chloasma,and to provide reference for clinical treatment and study of chloasma. METHODS:Retrieved from CBM,Wanfang database,CNKI and VIP,usingchloasmaas subject,the literatures of TCM therapy were collected during Jan. 2003-Dec. 2012. Bibliometric meth-od was adopted to analyze included literatures statistically in respects of publication amount,periodicals,research institution,litera-ture types,citing references,other periodicals citatien times,fund support,distribution of provinces and cities. RESULTS:During 2005-2012,the amount of the literatures increased slowly. Among top 10 journals in the list of publication amount,only Chinese Journal of Aesthetic Medicine was not TCM journal and took up the first place. Among top 7 research institutions in the list of publi-cation amount,TCM colleges took up predominant place,followed by TCM hospitals. The types of the literatures were mainly case report,contrastive study before and after treatment,group-divided control study;the amount of group-divided control studies increased gradually year by year. The references cited were mainly English literatures. There were 82 literatures which were cited by other periodicals more than 10 times;the highest time of other periodical citation per literature was 47 times;only 11 literatures were supported by fund. The institutions of literatures authors were distributed in 32 provinces,cities and autonomous regions of China,mainly in the eastern coastal areas. CONCLUSIONS:More and more attention has being paid to TCM therapy for chloas-ma,but the scope and depth of the studies were inadequate. From the point of view of modern medicine,we can explore the patho-logical TCM mechanism and the treatment method of shortening the course of disease.

Objective To compare the value of contrast-enhanced ultrasound (CEUS) and conventional ultrasound (CUS) in the localization and definition of different types of uterine myomas.Methods With real-time CEUS technique, 56 patients with uterine myomas proved by pathology were observed. The accuracy between CEUS and CUS in the localization and definition of different types of uterine myomas was retrospectively analyzed. Results The accordance rates of CEUS and CUS in the diagnosis of total uterine myomas, intramural myomas, submueous and subserous myomas were 94.6% (53/56) vs 73.2%(41/56),99.3%(31/32) vs 78.1%(25/32) and 91.6%(22/24) vs 66.7%(16/24),respectively,and in the definition of number and margin of myomas were 92.8 % (104/112) vs 80.30% (90/112) and 91.9 (103/112) vs 78.6 % (88/112). The accordance rates of CEUS and CUS in the diagnosis of typical uterine myomas were 95.8% (23/24) and 87.5% (21/24),and in the diagnosis of atypical uterine myomas were 93.8%(30/32) and 62.5% (20/32),which were different in statistics (P<0.05). Conclusions CEUS is better than CUS in revealing the number and margin of different types of uterine myomas. The accordance rates of CEUS were higher than those of CUS in the diagnosis of different types of uterine myomas and atypical uterine myomas. CEUS may be a new technique in the localization and definition of uterine myomas.

Objective To investigate the effect of dexmedetomidine on postoperative renal function of patients with rheumatic heart disease following valvular heart surgery. Methods Fifty patients following valvular heart surgery were randomized into experimental group and control group,with 25 cases in each group. The patients in experimental group receiveddexmedetomidine 0.5 μg/kg infusion 15min before induction, and then 0.5 μg/(kg·h) infused to the end of surgery, while those in control group received the same amount of saline in the same way. Blood from central venous was collected before surgery, at the end of surgery, 24 h and 48 h after surgery in order to detect Src, BUN and Cys C and the length of ICU duration was also recorded. Results Src and Cys C of the patients in both groups obviously elevated 24h after surgery when compared with pre-operation , while BUN elevated at both 24 h and 48 h after surgery(P < 0.05). Compared with those in control group, Src, BUN and Cys C were lower in experimental group ( P < 0 . 05 ) , and the length of ICU duration was shorter (P < 0.05). Conclusion Dexmedetomidine could improve the postoperative renal function after valvular heart surgery and lead to a better prognosis.

Objective To investigate the hemostatic function of biological glue in renal trauma.Methods Establishment of rab-bit kidney scratch,partial nephrectomy and renal injury penetrating wound models were available with a biological glue and hemo-static powder processing,observed and recorded the amount of bleeding and bleeding time.Tissue sample were transected from the wound of kidneys in each group after a month,and the renal wound healing condition was observed by pathological examination.Re-sults The hemostatic function of biological glue was better than styptic powder,the amount of bleeding in biological glue group and hemostatic powder group of kidney scratched model were(1.39±0.09)mL,(1.77±0.44)mL,the difference was not statistically significant(P =0.115);the bleeding time were(5.02 ±0.23)s,(66.40± 7.35)s,the difference was statistically significant(P <0.01);the amount of bleeding in two models of partial nephrectomy and renal penetrating wound were(2.07±0.25)mL,(11.42± 1.33)mL;(2.01 ± 0.36)mL,(3.95 ± 0.39)mL and bleeding time were(6.16 ± 0.69)s,(139.38 ± 8.97)s;(7.68 ± 0.80)s, (144.26±9.27)s,the differences were statistically significant(P <0.01).Pathology results showed that the wounds healed well. Conclusion The hemostatic function of biological glue in renal trauma were remarkable and stable,and was worth to be further promoted.

Objective To evaluate the safety and effectiveness of immunosuppression regimens,postoperative complications,dead causes and risk factors of lung transplantation (LTx).Methods The immunosuppression regimens and clinical data of 100 patients with end-stage lung diseases receiving LTx in our hospital were retrospectively analyzed between Sept.2002 to Dec.2010.There were 72 patients subject to single LTx and 28 patients to bilateral LTx,amongst them 61 patients received LTx under circulation support,including 5 cases of cardopulmonary bypass (CPB) support and 56 cases of extracorporeal membrane oxygenation (ECMO) support.The immunosuppression regimens including Cyclosporin,mycophemolate Mofeil and corticosteroids were utilized in 53 recipients before the year of 2007,and Cyclosporin was switched to Tacrolimus in 47 patients after 2007.All the patients received Daclizumab or Basiliximab as immunosuppression induction regimens.Results The 1-,2-,3-and 5-year survival rate after LTx was 73.3％,61.6％,53.5％ and 40.7％ respectively.The mean survival time post-transplant in the patients who received Cyclosporin-based regimens and Tacrolimus-based regimens were (36.57 ± 3.44) months and (35.00 ± 2.33) months,repectively,with no significant differences (P＞0.05).The main causes of mortality included primary graft dysfunction (PGD),acute rejection (AR),bronchiolitis obliterans (BOS) and sepsis.The incidence of AR and BOS in Tacrolimus group was significantly lower than that in Cyclosporin grou (P ＜0.05),but the incidence of diabetes mellitus was significantly higher in Tacrolimus group.Analysis of Spearman rank correlation revealed that there was a direct correlation between the incidence of AR and BOS (r =0.340,P＜0.01).The use of circulation support,diagnosis of IPF,postoperative complications such as AR,BOS and infection were associated with decreased survival time postoperatively,in both univariate and multivariate proportional hazards regression models (P＜0.05).Conclusion Cyclosporin-and Tacrolimus-based regimens were both effective immunosuppression strategies postoperatively,Consummate follow-up surveillance and prompt treatment of complications were the key points in prolongation of survival time and improving quality of life after LTx.
