After a concise review of the progress and achievements of burn works in the past 40 years the auther firmly pointed out that the currently most significant causes of death in burn injury are three,Inhalation injury,Infection and Internal organ injury, abbreviated as"Three I".The precent status and problems of"Three 1"are analyzed and the auther proprosed a model for planning burn research projects.In order to achieve an significant decrease of burn mortality,the auther also highlights that the crucial point is to protect the organism from damages to the body defense mechanism after burn injury.That is to say,in all dimensions and by all means,burn research projects should mainly focus on the early protection of the ability of the body defense mechanism.

The results of early resuscitation of 104 adult patients with BSA more than 50%were studied retrospectively. Although the mean amount of fluid replaced during 48h postburn was similar to the amount calculated with our formula, there existed significant individual differences. Therefore it seems not necessary to set up a rigid fluid replacement plan. To ensure adequate tissue perfusion, the fluid replacement formula might be modified as follows: 2 ml/kg/BSA%, with urinary output 30-40 ml/h, in the first 24h; and 1.5ml/kg/BSA%, with urinary output 40-50ml/h, in the second 24h. It should be emphasized that resuscitation should be started as early as possible,and adequate amount of fluid replacement is especially important during the first 2-3h postburn.There was no obvious relationship between the incidence of visceral complications and the total amount of fluid replaced during the resuscitation. Available data indicated that the amount of fluid calculated on the basis of our formula neither increased the incidence of early pulmonary edema nor influenced its development.As far as prevention of pulmonary edema was concerned, it did not seem justifiable to restrict the amount of resuscitation fluids. It was also noted that fluid therapy alone would not prevent entirely the development of postburn renal insufficiency.

A long course of systemic treatment with CsA in therapeutic dose to prolong skin allografts may produce severe toxic effects,therefore it is not acceptable for severe burn patients.Prior studies by one of us have reported that topical treatment with CsA will prolong the life of allografts.During the period of treatment,however,blood CsA levels were detected in high concentrations,similar to systemic use.The question occurs whether the immunosuppressive effect of topically applied CsA was due to local or systemic action.Two experiments were carried out.First,two skin grafts of ACI (RT1) ratswere transplanted on both sides of the back of same LEW (RT1) rat (n=56).The bandage was kept on for the first 5 postoperative days.One graft was treated topically daily with CsA 7.5mg/day in olive oil until rejection.At the same time,the other side was treated with olive oil alone as control.,The mean survival time (MST) was 12.38?0.70 and 9.14?0.33 d.,respectively,p

BACKGROUND:At present, spinal cord injury treatment is stil the worldwide difficult problem. Using the method of stem cells transplantation to treat the spinal cord injury is one of the hotspots of spinal cord injury repair research in recent years. OBJECTIVE:To summarize the progress and application prospects of stem celltransplantation in the treatment of spinal cord injury. METHODS:A computer-based search of PubMed and CNKI was retrieved for relevant articles concerning stem celltransplantation for treatment of spinal cord injury published after 2000. The keywords were“spinal cord injury, stem cell, celltherapy”in English and Chinese, respectively. Meta-analysis and secondary literature were excluded as wel as repetitive or old literature. Final y, 52 articles were included in result analysis. RESULTS AND CONCLUSION:This article summarizes types and biological characteristics of stem cells, basic mechanism, techniques and therapeutic efficacy of stem celltransplantation in the treatment of spinal cord injury, and proposes the issues and prospects concerning the stem cells transplantation for treatment of spinal cord injury.

The general data of 48.978 burn cases collected from 16 institutes and burn center in a period of 22 years (1958-1979) were analysed. It was found that the highest incidence of burns occurred in summer and before age of 30 (78.1%). particularly in the age group of 20-24 and under 5(22.97% and 22.95% respectively). Thermal burn was the commonest cause (89.57%). The ratio between female and male was 1:3. The ratio between cases with and without third degree burns was also 1:3. The burn extent was predominently under 30% TBSA (85.10%). cases with burn larger than 70% TBSA occupied less than 3% of the total. The exposed parts of the body. i.e. head, neck and limbs, were the prevalent areas affected. The mean hospitalization period was 26.9 days. The overall mortality rate was 4.93% and LA50 75.93%(Y = 7.5588-0.0337X). The incidences of shock and sepsis were 10.85% and 7.95% respectively. It was also found that the mortality rate (in terms of LA50). and incidences of both shock and sepsis have lowered remarkably (p

[Objective] To investigate X-ray and CT manifestations of tobereulosis of ankle joint and to discuss the differentiation with other diseases.[Method]The X-ray and CT findings in 5 cases with pathalogically proved tuberculosis of ankle joint were retrospectively analyzed.The differentiation with other diseases was discussed.[Result]The lesions involved entire right ankle joint in all 5 cases,The typical signs were as follows:(1)indistlnct and erosive joint surface,insect bitten-like of bony destruction ofjotht surface,digging-like shape of cancellous bone's destruction;(2)narrowed or irregular widened joint space;(3)ostooporosis of diseased region and surrounding;(4)extensive periostoal reaction of distal fibia and fibula;(5)to form cold abscess and sinus tract.[Conclusion]The tuberculosis of ankle joint earyies certain characteristic X-ray and CT signs,CT is better than X-ray in diagnosis.Highly alert of ankle joint tuberculosis is the key of early correct diagnosis.

Tamm-Horsfall protein(THP)was determined with radioimmunoassay in the urine and blood samples of 59 burn patients.It was found that urine and blood THP was significantly decreased postburn and the degree of decresing was correlated with the extent of the burnt body surface and the severity of renal damage.The changes of THP occurred earlier than those of the routine parameters for renal damage such as BUN or Cr.It is suggested that THP determination can be used as an index for the early damage of the Henle's loop and the distal convoluted tubules after burn injury.

Electrolyte imbslance.the changes of serum aldosterone and the ratio of an-giotensin Ⅱ/arterial natriuretic peptide were studied prospectiely in 59 cases of severe burns.Meanwhile,certain parameters of renal functions were detarmined.Hypernatremia devaloped in 6 cases.On the basis of our findings,it is believed that postburn hypernatremia might result from renal dysfunction and the greatly increased mediators,which can enhance the retention of sodium,might also play an important role in the development of postburn hypernatremia.
