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

As an important part of the health service security system,military medical equipment has important strategic position in wartime.Under the condition of high technology,the modern warfare has also laid higher requirement to the reliability guarantee of medical equipment.With the modernization development of military equipment,traditional medical equipment maintenance management mode does not meet the requirements of modern military medical equipment and its maintenance.Therefore,based on the reliability guarantee theory,the "Reliability Centered Maintenance(RCM)" management mode for military medical equipment is studied in order to achieve the purpose of improving the equipment reliability and the integrity of combat readiness.

Seventeen cases of postburn multiple organ failure (MOF) were studied prospectively.It was found that MOF mainly occurred in those patients with a burn area over 70% TBSA.Mortality rate of the cases of MOF was directly proportional to the number of organs involved.The incidence of pulmonary failure was the highest and the highest mortality was attributed to renal failure;MOF in the early stage after burns was mainly induced by burn shock and that in the late stage by burn wound infection.Endogenous infection seemed to be one of the important causes to precipitate the outbreak of postburn MOF.The morphological changes of the functionally failed organs were as follows:There were various degrees of cellular degeneration and necrosis.Or- ganelle changes such as swelling and vacuolization of mitochondria,enlargement of endoplasmic reticulum,gap formation of capillary endothelium etc were seen.Extravascular organ water volume of the functionally failed organs was increased.Stasis and/or hyperemia were found in the heart,the lungs,the liver and the GI,tract,but ischemia in the kidneys.The changes of the.enzyme spectrum of the myocardium,PaO2,RI,IB/DB,and DB were parallel to those of pathomorphology and extravascular organ water volume and they could reflect the severity of organ damages firly well.

Objective To study the ultrastructure of the anterior cruciate ligament.Methods Specimens were procured from seven patients with arthroscopy and observed under scanning and transmission electron microscope. Results Fibrils of normal anterior cruciate ligament arrayed in compact parallel form with waviness.Connecting fibers existed between fibrils.Diameters of fibrils were different with range of 30nm to 60nm mostly.Fibroblasts were distributed along with the fibrils.Active cells excrete filamentous collagen fibrils.Conclusion The ultrastructure of the anterior cruciate ligament was correlated with its function status.Mature fibroblasts existed in the ligament.

Objective To analyze the chest CT appearance of relapsing polychondritis with severer tracheobronchial malacia and improve diagnosis veracity.Methods Five patients with relapsing polychondritis received CT examination and the CT appearances were studied.Results The characteristic appearances in CT were throat tracheal and branch stenosis.The tracheal cartilages thickened and membranous wall was normal.Conclusions Distinguishability of CT is high,which can display the area and characteristics of the pathological changes CT examination is an efficient method of diagnosis of relapsing polychondritis,and can direct selecting treating methods.[Chinese Medical Equipment Journal,2008,29(2):84-85]

OBJECTIVE: To establish a RP-HPLC method for the determination of the content of Emodin in Fugan oral liquid.METHODS: The sample was separated on Zorbax SB-C18 column(150 mm?4.6 mm,5 ?m) with methanol-0.1%phosphoric acid solution(85∶15) as the mobile phase at a flow rate of 1.0 mL?min-1.The detection wavelength was set at 430 nm and the column temperature was 30 ℃.RESULTS: The calibration curve was linear at a range of 0.075 2 mg～0.376 0 mg(r=0.999 96) for the Emodin.The average recovery was 99.77% and the related standard deviation(RSD) was 1.03%(n=6).CONCLUSION: This method was proved to be simple,quick and reproducible and can be used for the quality control of Fugan oral liquid.

Objective: To investigate the clinical efficacy of treating herniation of lumbar intervertebral disc with electroacupuncture on Jiaji(Ex-B 2) points plus 3-D traction. Methods: To allocate 90 cases randomly into three groups and adopt therapies of 3-D traction, electroacupuncture on Jiaji(Ex-B 2) points and comprehensive method (combination of electroacupuncture on Jiaji(Ex-B 2) points and 3-D traction) and then compare the pre-treatment and post-treatment result with scores of clinical symptoms and clinical efficacy. Results: After 4-week treatment, the group of comprehensive therapy showed better effect than the other two groups. Conclusions:Electroacupuncture on Jiaji(Ex-B 2) points plus 3-D traction has positive effect on herniation of lumbar intervertebral disc.

Objective To study the influencing factors of digital image white balance of the biological microscope and the way to obtain optimized image.Methods Color temperature meter was used to measure the influences of the factors and their correlations, and SASS software was employed for statistical analysis.Results Object lens might increase the color temperature by 200 to 300 K, LBD color filter could enhance it by 400 to 1 800 K. Reducing field stop by 90% might decrease color temperature by 400 K. ND6 filter, ND25 filter and aperture diaphragm had no influences on color temperature.Conclusion The electric and optical parameters of biological microscope have to be adjusted to gain proper white balance for digital image.

An efficient and repeatable approach in transforming the foxtail millet (Setaria italica ) using Agrobacterium LBA4404 horboring the plasmid pBI121 was established. Factors affecting transformation efficiency were investigated including the genotype, explants, the density of bacteria, the duration for inoculation and co-cultivation, and the concentration of acetosyringone in the medium. The maximum transformation conditions were: the callus induced from inflorescence was used as explant; the duration for inoculation with Agrobacterium at low cell density was 30-40 min; for the co-cultivation , the suitable concentration of acetosyringone in the medium was 0.1 mmol/L, and the duration was 2 days.
