Objective To review our clinical experiences in the treatment of big area burn accompanying in-halation injury to explore the optimal preventive measures and therapy. Methods To analyze the clinical cases con-ducted of 20 such admitted the big area burn aeeornpanying inhalation injury from 2004 to 2007. Results 18 patients (90%) were cured and 2 patients(2%) died. Conclusion The curative rate of big area burn accompanied by inha-lation injury can be enhanced by combining various treatments,including early treat,early presentive tracheotomy,ap-propriate tracheobronchial lavage,and clear traeheoobronchial secretion.

Objective To study the expressions of YKL-40 and IL-1β in the cartilage of knee osteoarthritis(KOA),and analysis the possible relationship between YKL-40,IL-1β in KOA.Methods Thirty-eight patients diagnosed with KOA were selected in this hospital as observation group.Then select 30 articular cartilage cases in the same period due to knee injury knee joint examina tion or treatment of knee joint fracture surgery patients,referred to as the control group.According to KOA radiation and arthroscopic grading standards,the observation group was divided into 16 cases of mild group,10 cases of moderate group,11 cases of severe groups.Compare the expression levels of all patients including YKL-40,interleukin-1β (IL-1β),IL 6,tumor necrosis factor-α (TNF-α),while recording Mankin score and cell mortality.Results Expression of YKL 40,IL-1β,IL-6,TNFα,Mankin scores and rate of cell death about observation group were significantly higher than control group,the indicators above in mild,moderate,severe group showed a trend of rising(all P＜0.05).And the expression levels of YKL-40 and IL-1β were significantly positive correlation (r=0.738,P=0.000).In addition, The expression levels of YKL-40 had relation with IL 6 (r=0.819,P=0.000),TNF-α (r=0.871,P=0.000) and Mankin score (r=0.832,P 0.000),cells mortality deposit (r=0.832,P=0.000).Conclusion Expression levels of YKL-40 and IL-1β were significantly increased in cartilage of knee osteoarthritis patients,and there showed a significant positive correlation between YKL-40 and IL-1β.
