Objective:To investigate the change of the serum IL-18, sFas and sFasL levels in patients with severe burn and its correlation with the morbid condition and outcome Methods:Thirty patients, including three fatal cases, had burn with a total burn surface area (TBSA) of 30% or more 45 healthy volunteers were as control group The serum IL-18, sFas and sFasL levels were measured by enzyme-linked immunosorbent assay (ELISA) at various time points ( 1, 3, 5, 7, 14, 21, 28 and 35 days) burn later Results:Compared with control group, the levels of IL-18, sFas and sFasL of patients increased significantly after burn (P

OBJECTIVE:To obverse the efficacy and safety of tolynicate and napthylacetic acid and atorvastation combined with Danshen injection in the treatment of alcoholic hyperlipemia syndrome. METHODS:21 patients with alcoholic hyperlipemia syndrome were enrolled. All patients were given maintaining acid-base balance,oxygen inhalation and other conventional treatment. Based on it,they were orally given 75 mg Tolynicate and napthylacetic acid tablet,3 times a day+20 mg Atorvastatin calcium tab-let,once a day+4 ml Compound danshen injection,adding into 150 ml 5% Glucose injection by intravenous infusion,once a day. The treatment course for both groups was 30 d. Clinical efficacy,ALT,AST,TBIL,TC,TG,RBC and Hb before and after 6, 12,18,24 and 30 d,and incidence of adverse reactions were observed. RESULTS:After treatment,the total effective rate was 95.3%and incidence of adverse reactions was 28.5%. The ALT,AST and TBIL after 6,12,18,24 and 30 h and TC and TG after 18,24 and 30 h were significantly lower than before and gradually decreased by time;RBC and Hb after 12,18,24 and 30 h were significantly higher than before and gradually increased by time,the differences were statistically significant(P<0.05). CON-CLUSIONS:tolynicate and napthylacetic acid and atorvastation combined with Danshen injection is effective in the treatment of al-coholic hyperlipemia syndrome,with good safety.

Objective To investigate the change of insulin-like growth factor Ⅱ(IGF-Ⅱ) and its relation with infection in severely burned patients.Methods RIA method was used to determine the serum IGF-Ⅱ level in patients with severe burn.Results Compared with control group, the level of IGF-Ⅱ was increased significantly at 5 postburn days , and persistent 35 days (P0 05).Conclusion IGF-Ⅱ is involved in the pathogenesis of burn , and closely correlated with the infection after burn.

Objective To explore the levels of neuron-specific enolase(NSE)in serum and cerebrospinal fluid(CSF) of children with convulsion,and its significance to the diagnosis of neuronal damage was evaluated.Methods Sixty patients were enrolled,and they were divided into 4 groups:non-nervous system disease group,peripheral nervous system disease group,brief convulsion group,and prolonged/status convulsion group.The levels of NSE in serum and CSF were detected in 4 groups,and the electroencephalography(EEG) and computed tomography/magnetic resonance imaging(CT/MRI) examinations were taken to observe the changes in patients with convulsion.Results The levels of NSE in serum and CSF of children with convulsion increased significant,especially in the prolonged/status convulsion group.Changes of NSE levels in serum and CSF were similar.Meanwhile,significant changes were found in EEG between the brief convulsion group and prolonged/status convulsion group;but no significantly changes were found in CT/MRI between the 2 groups.Conclusions NSE detection might be valuable to the diagnosis for neuronal damage in early time.The changes of NSE levels are similar to those in EEG,which are more sensitive than the changes in CT/MRI.It is very important to combine the NSE detection in serum or CSF and EEG examination in early time after convulsion for judgement to the neuronal damage and prognosis.

OBJECTIVE:To study the therapeutic effect of Shenfu injection on sick sinus syndrome. METHODS: 125 patients with sick sinus syndrome were divided into two groups. 63 patients were given Shenfu by intravenous drip for 14 days as treatment group. The other 62 patients were given glucose insulin potassium(GIK) for 14 days as control group. The changes of clinical manifestations, electrocardiogram(ECG and DCG) and esophagus electrophysiological examination were compared between two groups with a randomized single blind design. RESULTS: Clinical therapeutic effect: The total effective rate of the treatment group was 87.3% ,while that of control group was 40.3% .There was significant difference between them(P

Objective To investigate the changes of cardiac aldosterone and mineralocorticoid receptor (MR) in Sprague-dawley (SD) rats with chronic heart failure (CHF) induced by isoproterenol (ISO). Methods The SD rats were randomly divided into CHF group (n=9) and normal control(NC) group (n=10). The experimental CHF group was induced by subcutaneous injection of ISO, and the NC group received same dose injection of sodium chloride. The heart function was evaluated with both echocardiography and hemodynamics. The contents of aldosterone in both plasma and heart were assessed by radioimmunoassay. The expression of MR was measured by Western blot and immunohistochemistry staining. Results Compared with NC group, the heart function was decreased in CHF group, the left ventricular ejection fraction was (38.8%±4.0%) in CHF and(79. 4%±4.6%), in NC group. The maximal rate of increase of ventricular pressure (+dp/dtmax) was (7164.4±502.6) mm Hg(1 mm Hg=0.133 kPa)/s in CHF and (10199.5±462.9) mm Hg/s in NC group (both P＜0. 01 ). The contents of aldosterone both in plasma and heart were higher in CHF group than in NC group [(0.63±0.06)μg/L vs. (0.3±0.07) μg/L, (0.41±0.05) μg/kgvs. (0.08±0.01)μg/kg, both P＜0. 01]. The MR expression was increased in CHF group versus in NC group (P＜0.01). Conclusions The heart function is decreased in rats with CHF induced by ISO, which is similar to dilated cardiomyopathy. The higher levels of aldosterone both in circulation and in heart as and well as MR expression upregulation in heart may play important roles in the pathogenesis of CHF induced by ISO.

The method of gene transfer into corneal endothelium was investigated to provide a foundation for the study of TGF-beta 1 gene transfer to inhibit corneal graft rejection. Two days after direct injection of pMAM TGF-beta 1 mediated by liposome into the anterior chamber of rabbits, one half of corneas were made into paraffin slides and the endothelial layer was carefully torn from the other half to make a single layer slide of endothelia. By means of immunohistochemical technique, the plasmid pMAM TGF-beta 1 expression product TGF-beta 1 in the endothelia was detected. Specific TGF-beta 1 expression was positive in the endothelia on both the paraffin slide and the single layer slide. The results showed that by direct injection into the anterior chamber, foreign plasmid DNA could be transferred into the endothelia and its expression was obtained. This may provide a foundation for further study on TGF-beta 1 participating in local induction of corneal immune tolerance.

BACKGROUND:Experiments have shown that the col agen substrate has the capability of stimulating cartilage generation, but the stimulating role of different types of col agen substrates remains controversial. OBJECTIVE:To investigate the effect of type I and type II col agen on the biological characteristics of human chondrocytes cultured in vitro. METHODS:Human chondrocytes at passage were cultured onto the ordinary culture plates (ordinary plate), type I col agen-coated culture plates (type I plate), and type II col agen-coated culture plates (type II plate). cellgrowth curves were determined by MTT method after cells were cultured for 10 days. By ELISA, PCR, and 1,9-dimethyl methyleneblue technology, type I and type II col agen and glycosaminoglycan contents were quantitatively detected in cartilage cells 28 days after culture. RESULTS AND CONCLUSION:The number of cartilage cells was the highest in type II plate, which was twice of that in type I plate and five times of that in ordinary plate. Cartilage cells in type II plate secreted the least amount of type I col agen, which showed significant differences compared with the ordinary plate (P<0.01) and had no statistical y significant difference with type I plate (P>0.01). Cartilage cells in type II plate secreted the most amount of type II col agen and glycosaminoglycan, showing significant differences compared with the other two plates (P<0.01). The cartilage cells cultured in col agen plates are better than that cultured in ordinary culture plate, type II col agen culture plate is better than type I col agen culture plate in maintaining cellshape, extending the dedifferentiation pattern, and promoting celldifferentiation.
