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 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 study the clinical significance of liver pathological changes in patients with rheumatic heart valve disease (rheumatic heart disease, RHD). Methods: Forty one patients with RHD and tricuspid valve incompetence in 30 patients underwent heart valve replacement. Light microscopy and H 800 transmission electron microscopy were used to observe liver tissue harvested by biopsy performed before institution of cardiopulmonary bypass. Results: Typical pathological changes of liver as the following: (1) Changes of liver intercellular substance including sinusoid widening, blood stasis, liver fibroplasia. (2)Hepatocyte changes: hepatocyte swollen, mitochondria swollen, crest disappearence, hepatocyte degeneration and necrosis. There was correlation between liver pathological changes and magnitude of tricuspid valve regurgitation. Conclusion: To improve liver pathological changes, it is important to operate on patients with rheumatic heart diseases and tricuspid valve incompetence as early as possible and to eliminate tricuspid valve regurgitation.

Objective:To study the change of plasma cyclic nucleotide in patients of rheumatic heart disease with pulmonary hypertension and to evaluate the relationship between plasma cyclic nucleotides and hemodynamics. Methods:Plasma cGMP and cAMP were examined by radioimmunoassay, hemodynamic data were obtained with Swan Ganz catheter and the HP compact configurable monitors. Results:Plasma cyclic nucleotide increased in patients of rheumatic heart disease with pulmonary hypertension and had an obvious correlation with the level of PAPM, PVR, PAWP and CI. Conclusion:Increased cAMP and cGMP is one of the pathophysiological characters of pulmonary hypertension, cAMP and cGMP, as the second messenger, may play an important regulating role in the development of pulmonary hypertension.

Objective To observe the clinical effects of radiotherapy and/or chemotherapy in the treatment of nasal and Waldeyer ring natural killer (NK)/T cell lymphoma and to analyze the prognostic factors.Methods Between January 20,2000 and December 21,2010,109 patients with nasal NK/T cell lymphoma and 21 patients with Waldeyer ring NK/T cell lymphoma were admitted to our hospital; the diagnosis was confirmed by immunohistochemistry.According to the Ann Arbor staging system,116 patients were classified as stage Ⅰ E,and 14 as stage Ⅱ E.Thirty patients received radiotherapy alone;2 patients received chemotherapy alone; 98 patients received radiochemotherapy.Results The follow-up rate was 100％.Seventy-eight patients were followed up for at least 5 years.The complete remission (CR) rate was 89.2％ in all patients.The CR rates of stage Ⅰ E patients and stage Ⅱ E patients were 88.8％ and 92.9％,respectively (x2 =0.02,P =0.837).The CR rates of patients receiving radiotherapy alone and patients receiving radiochemotherapy were 86％ and 96％,respectively (x2 =1.44,P =0.230).The five-year overall survival (OS) rate and disease-free survival (DFS) rate of all patients were 58.0％ and 57.2％,respectively.The five-year OS rates of stage Ⅰ E patients and stage Ⅱ E patients were 60.6％ and 36.3％,respectively (x2 =0.25,P =0.615) ;the five-year DFS rates of stage Ⅰ E patients and stage Ⅱ E patients were 59.7％ and 36.3％,respectively (x2 =0.21,P =0.648).The five-year OS rates of patients receiving radiotherapy alone and patients receiving radiochemotherapy were 70.0％ and 48.4％,respectively (x2 =0.01,P =0.933) ; the five-year DFS rates of patients receiving radiotherapy alone and patients receiving radiochemotherapy were 65.6％ and 48.4％,respectively (x2 =0.09,P =0.764).The grade 3-4 toxicity rates of radiotherapy alone and radiochemotherapy were 6.7％ and 54.1％,respectively (x2 =41.38,P=0.002).The radiation dose to the primary lesion and Eastern Cooperative Oncology Group (ECOG) score were correlated with OS (x2 =3.1 8,P =0.005 ; x2 =2.97,P =0.008).Conclusions The clinical effect of radiochemotherapy is similar to that of radiotherapy alone in the patients with stage ⅠE and ⅡE nasal and Waldeyer ring NK/T cell lymphoma,but radiochemotherapy has higher toxicity than radiotherapy alone.The radiation dose to the primary lesion and ECOG score are the influential factors for OS.

Objective The long-term effects of cell transplant on cardiac function are unknown. Therefore, we tested the survival and functional impact of rat autologous smooth muscle cells up to 12 weeks after transplant into infracted hearts. Methods Autologous smooth muscle cells were acquired from the ductus deferens of adult Sprague-Dawley rats(weight,300g), and cultured for 4 weeks before transplant. 4 weeks after left coronary artery ligation, the cultured cells(4?10 6 , n=10), marked with 5-bromo-2'-deoxyuridine(BrdU), or culture medium alone(n=10) were injected directly into infarcts of the heart. Cardiac function was assessed by echocardiography before and 12 weeks after transplantation. BrdU in the cells and smooth muscle cells were identified by immunohistochemical staining technique using monoclonal antibodies against BrdU and ?-smooth muscle actin. Results Grafted autologous smooth muscle cells were presented in infarcts and formed musclelike tissue. They thickened the wall of the left ventricle〔(2.36?0.31) vs (1.03?0.11)mm,P
