The incidence of local recurrence after wide local excision and radiation of soft tissue sarcoma (STS) ranges from 5％ to 20％.The optimal management of locally recurrent STS must be individualized.Approaches for retreatment include wide local re-excision followed by a variety of radiation which include external-beam radiation,brachytherapy and intraoperative electron radiotherapy.Following retreatment,the likelihood of ultimate local control ranges from 37％ to 100％.However,each radiation technique could produce severe side effects,and so for selected patients,repeat irradiation may be unnecessary.

Objective To analyze the effect of one-part form mini-implant in treatment of immediately and delayed repair of edentulous space. Methods Retrospectively analyzed 80 cases of edentulous space patients in our hospital from Jan. 2009 to Jan. 2011, and divided them into the immediately repair group ( observation group) and the delayed repair group ( control group) according to time of edentulous space repair. Patients of the two groups were given permanent PFM 3 months later, and regular clinical and X-ray examinations were made to evaluated clinical efficacy and complications of the two groups. Results The score of ISQ of the observation group was higher than that in the control group with significant difference (P <0. 05); and the postoperative complications of the observation group was significantly decreased compared to the control group with a significant difference (P <0. 05). Conclusion Mini-implant used in immediately repair in edentulous space can remove pain in a short time with less postoperative complications, it has more advantages than delayed repair of edentulous space.

Objective To investigate the prevalences of metabolic disorders of glucose and lipids in the first degree relatives (FDP) of type 2 diabetic patients in Qingdao,China. Methods 1392 subjects were recruited,including 528 T2DM-FDR(parent and/or siblings have T2DM) and 864 NC-FDR(parent and siblings did not have DM). All subjects received both standard 75g oral glucose tolerance test and measurements of body weight,height,waist and hip circumference,percentage of body fat,blood pressure,blood lipid,and plasma uric acid. Results (1) The prevalence of diabetes was higher in DM-FDR than in NC-FDR (24.24% vs 17.01%,P

Objective:To examine the sodium-hydrogen exchanger(NHE-1) m RNA expression in lung of patients with congenital heart disease,and to explain the cause of pulmonary vascular remodeling.Methods:Twenty-two patients with congenital heart disease were divided into 2 groups:non-pulmonary-hypertension group(s PAP

Objective: To assess the hydrodynamic performance of C L pugestrut valve prosthesis in vitro . Methods: The leakage, steady flow and pulsatile flow of the valve prosthesis was tested in vitro with the C L standard valve and Medtronic Hall valve prosthesis as control. Results: The rate of leakage of the C L pugestrut valve was (298?66) ml/min, accorded with the demand of clinical use. The steady flow pressure drop across the C L pugestrut valve was significantly lower than the C L standard valve( P

Objective To evaluate body surface localization by virtue of lnnova CT reconstruction combined with DSA guidance in performing percutaneous fine needle biopsy of lung lesions. Methods Twenty-one patients with solid lung lesions were enrolled in this study. Before percutaneous lung needle biopsy, DSA rotation scanning was performed. Based on the reconstructed lnnova CT images, precise puncture scheme was formulated. Then, under DSA guidance, pereutaneous fine needle biopsy of lung lesions was carried out. Results A total of 41 percutaneous fine needle biopsies was made, of which definite pathologic diagnosis was obtained in 40, with a positive rate of 97.6%. Pneumothorax occurred in one patient (4.8%). Conclusion Percutaneous lung needle biopsy with the help of body surface localization, which is determined by Innova CT reconstruction images, and DSA guidance is a safe and technically-simple procedure with high accuracy in localization. It is of great value in the diagnosis of pulmonary space-occupying lesions.

BACKGROUND: Cell transplantation is a new technique to treat myocardial ischemic diseases in recent years. There are not many reports regarding smooth muscle cell(SMC) transplantation at moment.OBJECTIVE: To investigate the impact of autologous SMC transplantation on the survival and the restoration of cardiac function after myocardial infarct.DESIGN: An observatory comparative study based on experimental animals.SETTING: Institute of cardiothoracic surgery in a military medical university of Chinese PLA.MATERIALS: The study was conducted in the Institute of Cardiothoracic Surgery of the Second Military Medical University of Chinese PLA from January 2003 to June 2003. Totally 24 male adult SD rats in cleanness grade with a body mass of(300 ± 20) g were randomly divided into two groups,i. e. ,transplant group and control group with 12 rats each. All rats were fed in clean environment.METHODS: Autologous SMC was separated and extracted from the ductus deferens of SD rats by enzymic digestion for culture and amplification in vitro. BrdU-labeled autologous SMC was directly injected into the scarring tissues of cardiac infarct area induced by the ligation of anterior descending branch of left coronary artery 2 weeks ago in rats of transplant group. DMEM culture medium of same volume was injected into the rats of control group. Cardiac function was evaluated by ultrasound examination before and 4 weeks after transplantation. The survival of the transplanted SMC and its effect of vasoformation in myocardial scarring tissues were detected by immunohistochemical staining.soformation in myocardial scarring area after autologous SMC transplantation;after transplantation.RESULTS: Transplanted autologous SMC survived and formed muscle-like tissues in myocardial infarct area. Compared with control group, left ventricnlar end diastolic volume(LVEDV) of transplant group was significantly reduced( P < 0.01), left ventricular ejection fraction(LVEF) was significantly elevated( P < 0.01 ), and the vasoformation in myocardial scarring tissue was significant( P < 0.01 ).CONCLUSION: Autologous SMC transplantation can prevent ventricle enlargement after myocardial infarct, promote vasoformation in infarct area, and ameliorate cardiac function.

To investigate the electrophysiologic characteristics of f-wave amplitude and to evaluate its role in development and persistence of chronic atrial fibrillation (AF) associated with rheumatic heart disease (RHD). Methods: Epicardial mapping was performed in 44 patients with chronic AF of RHD who underwent heart valve surgery. Ten patients with supraventricular tachycardia served as the control group. Results:The f-wave amplitude of left atrium (LA) and middle and low LA posterior regions were significantly lower than those of the control group. The f-wave amplitudes of the upper, middle and low sections in LA posterior region were significantly lower than those in right atrium (RA) (P<0.05). The f-wave amplitudes were compared before and after electrocardioversion in 14 patients with chronic AF. The mean atrial electrogram amplitude during sinus rhythm was significantly higher than that during AF (P<0.01).The f-wave amplitude in left appendage was higher than that in LA posterior region (the upper,middle and the lower part),P<0.05.The f-wave amplitude in the upper section of LA was significantly higher than that in the middle section. The f-wave amplitude in AF group was not correlated to the diameter or volume of both atria. Conclusion: There are amplitudes differences between the upper, middle and lower LA,suggesting that the middle and lower sections of LA posterior wall may be the region producing anisotropy and reentrant circle.

This study tested the hypothesis that controlled reperfusion with warm blood cardioplegia containing mannitol would result in more effectively improved recovery of myocardial mitochondrial function by preventing or reducing a potentially harmful component of reperfusion. Myocardial mitochondrial function was significantly depressed after 60 min reperfusion, but slightly depressed in the controlled reperfusion group. Significantly increased MDA content and decreased SOD activity were observed after 60 min reperfusion. Hearts in the controlled reperfusion group had low MDA content and might protect the activity of SOD. The- results indicate that controlled reperfusion after ischemia provides benefit in avoiding myocardial mitochondrial reperfusion injury.
