Objective To develop rescue device for pilots in air accidents and solve the problem that it's difficult for medical staff to carry out on-board rescue because of the height from the ground to the cockpit edge of the fighter plane. This device with hydraulic system is multi-use: it can be joined to the plane as a ladder and tied in an ambulance as a stretcher. The medical support level of air force dump and station will be improved after using it. Methods 6082 aluminium alloy for aeronautic with advanced and matured technology was utilized to weld the principal part. The fissions can be fitted together and drawn out. The cantilever with hanger was applied. The active and diagonal crutches and the separable composite structure were also used. Results With this device, two staff can board the fighter plane to carry the wounded pilot to the sliding seat which is stably controlled by hydraulic system and then after quick sliding and separating from the device, the seat become a stretcher, and thus it can avoid the second carrying to the pilot. Using this device, the rescue work on-board become faster, more steady and safer. Conclusions This device can provide on-board rescue for pilots of forced landing in air accidents and it can be configured in a new kind of outfield ambulance for both military and civilian purposes. Because of being simple in frame and light in weight, it is easy to take or transport.

To investigate the possible effects of cyclosporine A(CsA) on the T cell dependent liver injury induced by Concanavalin A (Con A) in Kunming mice,25 Kunming mice were randomly divided into five groups. Con A (doses of 10mg/kg, 20mg/kg and 40mg/kg) was administered via the tail vein to duplicate the liver injury as the ConA group; CsA subcutaneously injected twice at doses of 130mg/kg 15 hours and 1 hour respectively before ConA challenge constitutes the CsA group. Phosphate buffered saline (PBS) only served as the control group. Blood samples for tumor necrosis factor alpha (TNF ?) and alanine aminotransferase (ALT) measurement were obtained at 8 hours after ConA administration. Histopathological examination was also performed for liver tissue. The results showed that ConA induced specific liver injury in Kunming mice was successfully duplicated. CsA markedly protected the mice from Con A induced liver injury by comparing the levels of serum ALT(44?16U/L vs 341?52U/L, P

Objective To study the influence of economic level on nutrition intake and status in adult. Methods The survey of income level, and nutrition intake and status of adults in 2000 in the city and rural area of Hunan province was carried out, and was compared with the data of the first survey in 1991. Results With the income increasing, the intake of protein,calcium,iron, retinal EQ and riboflavin increased from 1991 to 2000. In the population with low and middle income, the inadequate intake of calcium, retinal EQ and riboflavin was common. With the economic level being raised, the number of people with overweight or obesity(BMI≥25) increased, especially in city. But the number of people with malnutrition (BMI

Objective:To determine the protective effect of cardio-pulmonary bypass(CPB) with autologous lung as oxygenator on CPB-relative inflammatory response.Methods:Twelve adult mongrel dogs were randomly divided into control group and study group.Cardiopulmonary bypass (CPB) using a membrane oxygenator (control group) or using the autologous lung (study group) for gas exchange was performed for 120 min in an alternating series of 12 mongrel dogs with the heart arrested for 90 min by crystalloid cardioplegia and 30 min reperfusion.The blood samples were collected at the same time point of pre-operation(T1),60 min of cardiopulmonary bypass(T2),and 1 hour(T3),2 hours(T4) after cardiopulmonary bypass. Plasma concentration of IL-6,IL-10,TNF-α were detected with ELISA.Results:The plasma levels of IL-6,IL-8,IL-10,TNF-α in each group were significantly increased at T2,T3,T4.The plasma levels of IL-6,IL-8 and TNF-α in study group were significantly lower than in the control group at T2,T3,T4.The plasma levels of IL-10 in study group were significantly higher than the levels in control group at T2,T3,T4.Conclusion:This study indicates that extracorporeal circulation with autologous lung as oxygenator could reduce the increased amplitude of plasma levels of TNF-α,IL-6 and IL-8 whereas enhance the increased amplitude of the plasma IL-10 levels that result from CPB.In other word,extracorporeal circulation with autologous lung as oxygenator possesses the effect to regulate inflammatory cytokine balance and down-regulate CPB-relative inflammatory response.
