Objective To observe the effect of functional training combined with Chinese medicine hot pack-electrotherapy on knee osteoarthritis. Methods60 patients with knee osteoarthritis were divided into two groups. The treatment group was treated with functional training combined with Chinese medicine hot pack-electrotherapy; the control group was treated with Chinese medicine herbs hot pack-electrotherapy only. They were assessed with Lysholm Knee Scale. ResultsAfter treatment, the scores of Lysholm Knee Scale improved significantly in both groups (P=0.000), and more in the treatment group than in the control group (P=0.013). ConclusionFunctional training combined with Chinese medicine hot pack-electrotherapy is an effective and safe treatment for knee osteoarthritis.

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 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 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 compare the quality of life before ischemia postconditioning and 6 months after ischemia postconditioning in patients with acute ST segment elevation myocardial infarction,and investigate the related risk factors.Methods One hundred and twenty-nine patients with acute ST segment elevation myocardial infarction were given the ischemie postconditioning.The quality of life was evaluated before ischemia postconditioning and 6 months after ischemia postconditioning by 36-item short-form health survey (SF-36) and seattle angina questionnaire (SAQ).Results In acute ST segment elevation myocardial infarction patients treated with ischemia postconditioning,the scores of SF-36 and SAQ were significantly lower at 6 months after ischemia postconditioning than those before ischemia postconditioning [SF-36:total score of body health (76.4 ± 17.3) scores vs.(56.3 ± 16.8) scores,physiologic function (75.3 ± 18.1) scores vs.(52.4 ± 19.2) scores,physiologic functional authority (75.6 ± 16.5) scores vs.(48.5 ± 20.3) scores,body pain (77.2 ± 15.4) scores vs.(58.7 ± 16.6) scores,total health state (73.6 ± 17.8) scores vs.(50.6 ± 14.7)scores,total score of mental status (77.5 ± 15.3) scores vs.(55.3 ± 17.3) scores,vitality (69.3 ± 18.1)scores vs.(43.2 ± 17.4) scores,society function (70.3 ± 17.5) scores vs.(41.3 ± 14.2)scores,affection functional authority (80.2 ± 17.4)scores vs.(63.5 ± 14.3)scores,mental health (77.6 ± 18.4) scores vs.(55.6 ± 20.1) scores,health change (76.3 ± 17.4) scores vs.(53.4 ± 16.6) scores;SAQ:body limitation of activity (78.46 ± 12.21) scores vs.(35.34 ± 15.33)scores,angina stable state (74.23 ± 8.53) scores vs.(30.12 ± 5.38) scores,angina episode state (72.34 ± 10.33) scores vs.(27.33 ± 9.12) scores,satisfaction degree of treatment (76.42 ± 12.13)scores vs.(30.56 ± 15.57) scores,knowledge of diseases (74.22 ± 9.35)scores vs.(37.25 ± 20.32) scores] (P ＜ 0.05).The results of multiple linear regression equation showed that the older,more severe vascular lesions,and lower total score of body health score before ischemia postconditioning indicated lower total score of body health,and worse quality of life after ischemia postconditioning.Conclusions The quality of life of patients with acute ST segment elevation myocardial infarction after ischemia postconditioning is significantly improved,compared with that before ischemia postconditioning.Advanced age,vascular disease and lower total scores of body health before ischemia postconditioning are independent risk factors of total scores of body health after ischemia postconditioning.

Objective To investigate the effects of target-controlled infusion (TCI)of dexme-detomidine on the median effective concentration of effect-site (Ce50 )of propofol at loss of conscious-ness (LOC)in patients.Methods Sixty-four patients,28 males and 36 females,aged 20-60 years, ASA physical status Ⅰ or Ⅱ,scheduled for elective surgery,were randomly allocated to receive dexmedetomidine of 0 ng/ml (group P),dexmedetomidine of 0.4 ng/ml (group D1),dexmedetomi-dine of 0.6 ng/ml (group D2)and dexmedetomidine of 0.8 ng/ml (group D3)for 1 5 min before TCI of propofol,n =1 6 in each group.The propofol infusion was started to provide an effect-site concen-tration of 1.0 μg/ml,and increased by 0.2 μg/ml when propofol effect-site concentration and target concentration were equilibrium until LOC.Results The Ce50 (95%CI )at loss of consciousness in groups P,D1,D2 and D3 were 2.30 (2.24-2.36)μg/ml,1.92 (1.87-1.96 )μg/ml,1.60 (1.55-1.65)μg/ml and 1.41 (1.35-1.45 )μg/ml,respectively.There was a negative correlation between the effect-site concentration of propofol-induced LOC and target concentration of dexmedetomidine (r=-0.84,P <0.01).Compared with groups P,D1 and D2,the incidence of bradycardia was higher in group D3 (P <0.05).Conclusion The Ce50 of propofol-induced LOC gradually decreases with in-creasing target concentration of dexmedetomidine.Combining propofol with dexmedetomidine of 0.4 or 0.6 ng/ml that can reduce the Ce50 of propofol-induced LOC,which is suitable for induction of an-esthesia with a lower incidence of bradycardia.

Objective To evaluate the sedative interaction between dexmedetomidine and propofol.Methods Sixty-four American Society of Anesthesiologists physical status Ⅰ or Ⅱ patients,aged 20-60 yr,with body mass index of 19.0-25.0 kg/m2,scheduled for elective surgery under general anesthesia,were allocated into 4 groups (n =16 each) using a random number table:different target concentrations of dexmedetomidine groups (D1-4 groups).Dexmedetomidine was administered by target-controlled infusion (TCI) with the Markku model.The target plasma concentrations of dexmedetomidine were 0,0.4,0.6 and 0.8 ng/ml in D1-4 groups,respectively.At 15 min of dexmedetomidine TCI,propofol was given by TCI with Schnider model,and the initial target effect-site concentration was set at 1.0 μg/ml.After the target effect-site and plasma concentrations were balanced,the target effect-site concentration of propofol was gradually increased in increments of 0.2 μg/ml until loss of consciousness (Observer's Assessment of Alertness/Sedation Scale score was 1).The model of pharmacodynamic interaction was used to analyze the sedative interaction between the two drugs.Results There was no statistically significant difference in residual sums of squares fitted by using the model of pharmacodynamic interaction between the target effect-site concentration of propofol and target plasma concentration of dexmedetomidine at loss of consciousness (P＞0.05).The linear dimensionless parameter of pharmacodynamic interaction was 0.The median effective effect-site concentration of propofol was 2.38 μg/ml at loss of consciousness,and the median effective plasma concentration of dexmedetomidine was 2.03 ng/ml at loss of consciousness.Conclusion Dexmedetomidine and propofol interact additively in terms of sedation.
