Objective To sum up the experiences of tongue repair after radical operation of tongue carcinoma with free forearm flap in the last two years. Methods The clinical data of 26 patients underwent forearm free flap transfer for tongue repair from February 2002 to February 2004 were retrospectively analysed . Results Among the 26 grafted forearm flaps, 25 survived. Only one flap occurred arterial thrombosis and necrosis after the second operation.All the patients were followed up for 6 months to 2 years. Reconstruction tongues had suitable volume and shape as well as perfect movement ability. Conclusion Free forearm flap was suitable to repair the tongue defect after radical operation of tongue caicinoma. The rate of operation success was high, and reconstructed tongues could basically meet patient's normal life.

The data analysis of food supervision needs to reflect the integration of food safety and possible trend based on the fun-damental test data of stressed foods and their products. With the assessment and analysis on potential resources of hazard elements, the integrate management support of food safety could be achieved. The data management could be organized and evaluated through plan, collection, treatment and display, which might be assisted to establish data-link with process mining to enforce the prospect of food safety background and trend and to provide the support of food safety management.

Objective To determine the main predictors of circulatory crisis after replantation in patients with severed distal finger so as to establish the theoretic basis in reducing the morbidity of circulatory crisis. Methods 65 severed distal fingers underwent replantation were respectively reviewed. All the clinical parameters including age, sex, dominant hand or finger, preservation of the severed finger, platelet level, ischemia duration, cause of injury, manner of venous drainage, repair of artery, order of reparation and plane of division were investigated as predictive risk factors for circulatory crisis of finger after replantation. In order to find the risk factors of circulatory crisis, the data was dealt with t test, ?2 test, analysis for variance or multivariate Logistic regression analysis. Results 13 replanted finger suffered from impaired circulation in 65 fingers. Univariate analysis demonstrated that many factors were significantly correlated with the circulatory crisis of finger, such as the manner of venous drainage(?2=6.714,P=0.035), the cause of injury (?2=9.049,P=0.011), the preservation of severed finger(?2=6.452,P=0.040), the age(?2=14.838,P=0.001), the platelet level(uc= 2.961, P=0.003). The multivariate Logistic regression analyses showed that platelet level (OR=1.015, P=0.030), the age(OR=0.349, P=0.031) and the manner of venous drainage(OR=0.278,P=0.036) were the significant independent predictors for circulatory crisis. The incidence of circulatory crisis in patients less than 6 years old was 61.5%, significantly higher than any other age group(P

Objective To study the effect of tail-suspending on myostatin(MSTN)expression in the soleus muscle of rats.Methods The MSTN mRNA levels in soleus muscle of tail-suspended and normal control rats were measured and compared.Results The MSTN mRNA in soleus muscle of tail-suspended rats was 2.2 times(hind limb unloading for 14 days)and 3.5 times(hind limb unloading for 30 days) higher than that in normal control rats (P<0.05).The relative wet weight of the soleus muscle in tail-suspended rats was decreased by 11%(unloading 14 days)and 1 9%(unloading 30 days),respectively,compared with that in normal control rats.Conclusion The expression of MSTN mRNA is elevated in the soleus muscle of tail-suspended rats,probably due to atrophy of the soleus muscle.

Objective To improve the management and utilization of hospital sterilizing devices. Method Strict and operable managerial system was established. Result Hospital sterilizing devices behaved well. Conclusion Just like the purchase, utilization and maintenance of large-scale equipments, the ones of hospital sterilizing devices also should be integrated to optimize their performances.

According to the recognition of medical engineering department after the army reform,this paper puts forward some suggestions on the transform and development of medical engineering function.

Objective To explore the surgical technique of applying the third retrograde 3rd dorsal metacarpal artery island flap with d orsal metacarpal superficial vein i n order to expand the repairing range of the3rd dorsal metacarpal artery island flap and increase the survival of the flap.Methods After 1999,13cases of the dorsal and pulp soft tissue defect of the 3rd and 4th fingers were designed to be repaired with the third dorsal metacarpal artery island fla p with dorsal metacarpal superficia l vein.The flap pedicle carried the 3rd dorsal cutaneous nerve and superficial metacarpal vein.The flap axis extended proximally 6cm along the original axis.The flap was harvested according to t he axis of the superficial vein.Results All flaps survived completely and2cases seemed survived as vein flaps.Consclusions This surgical technique can be used t o expand the re-pairing range of the 3rd dorsal metac arpal artery island flap,and be suitable to repair the dorsal and pulp soft tissue defcts of the 3rd and 4th finge rs.The one stage operation is simple,practical and effective.

The traditional treatment of abdominal aortic aneurysm was open surgery.In the 1990s,endovascular abdominal aortic aneurysm repair (EVAR) began to emerge.In the early stage,this kind of minimally invasive method was applied in highly selected patient cohort due to the limitation of anatomic conditions of patients,age of patients and shortage of available endovascular devices.The indications for open surgery which were used in this new kind of therapeutic modality also influenced the outcomes.As the technique became mature and the properties of endogarft were developed,endovascular treatment can be used to treat more complex pathologies and the results were improved.However,several challenges were rising,including dealing with complex proximal aneurismal neck,intra-and post-operative endoleak,abdominal aortic aneurysm compromising branched arteries and ruptured abdominal aortic aneurysm.To solve these problems,chimney technique,fenestrated stent,branched stent and the sandwich technique had been invented and developed.It is believed that endovascular treatment for abdominal aortic aneurysm could be applied more widely under vascular surgeons' efforts.
