[Objective]To discuss the clinical outcomes of low-energy tibial plateau fractures treated with arthroscopy-assisted operative management and locked by LCP.[Method]From January 2006 to March 2007,15 patients with tibial plateau fractures(SchatzkerⅠ,Ⅱ)were reduced with arthroscopy-assisted and treated by LCP and bone defects were filled with homogeneous allograft bone.[Result]With follow-up visits for 12～26 months,all cases were healed.According to creiteria of Rasmussen,excellent were in 10 cases,good in 4 cases,fair in 1 case,with the rate of being excellent and good added up to 93%.[Conclusion]LCP fixation is an effective technique for the low-energy tibial plateau fractures treatment with the advantage of less invasion,steadier fixation and lower complication rate.Arthroscopy-assisted operative management can help to reduce reduction loss from intra-articular more precisely to reach a higher union rate.It is also a preferable method for low-energy tibial plateau fracutures treatment(SchatzkerⅠ、Ⅱ).

Objective To investigate the role of anti apoptosis gene bcl 2 in the survival of cultured uveal melanoma UM cells. Methods Antisense oligodeoxynucleotides (AS ODN) bcl 2 were delivered with cationic lipid to primary cultured UM cells. The inhibitory effect of AS ODN bcl 2 on proliferation of UM cells was examined by 3, 4,5 Dimethyliazol 2,5 diphenyl tetrazolium bromide (MTT) method. Using DNA ladder to determine if the UM cells had been apoptotic. Bcl 2 expression was detected by RT PCR and Westernblot technics. Results The effect of AS ODN bcl 2 in inhibiting the proliferation of cultured UM cells had opposite relation to dosage. It down regulated the mRNA and protein level of bcl 2 gene, and the sense ODN didn′t have this effect. Conclusion AS ODN bcl 2 can down regulate bcl 2 expression, inhibits UM cells proliferation and induces apoptosis.

Objective To investigate the protective effects of mild hypothermia on cells in the CA_1 region of the hippocampus in gerbils following global ischemia-reperfusion injury(IRI),and to explore their mechanism. Methods IRI models were established in 75 gerbils.Any changes in TUNEL positive cells and the expression of Bax and Cytochrome C were then observed in normothermic(N) ,hypothermic(H)and sham(S) groups through immu- nohistochemistry methods.Results In the H group(as compared with the N group)apoptotic cells in the CA_1 sub- field of the hippocampus significantly decreased.The expression of Bax and Cyt C at 3 h,6 h and 1 d were de- creased,and the expression fastigium was delayed.Conclusion Mild hypothermia can moderate and delay cell ap- optosis,and its mechanism might be related with reducing and delaying the expression of Bax and Cyt C released by mitochondria.

Objective To explore the protective effect of L-carnitine on neonates with myocardial injury caused by as?phyxia. Methods Forty-four neonates with myocardial injury caused by asphyxia were randomly divided into L-carnitine treatment group (21 cases) and control group (23 cases). Patients in control group were received routine treatment and pa?tients in treatment group were given L-carnitine 0. 1 g/(kg · d) on the basis of routine treatment for 7 days. Symptoms and physical signs were observed before therapy and during the treatment in two groups. Before and after the treatment, plasma levels of free L-carnitine and cardiac troponin I (cTnI) were detected with the method of colorimetric assay and chemilumi?nescent, respectively. Results The clinical effective rate was significantly higher in treatment group than that of control group (90.48%vs 60.87%, P<0. 05). Compared with the control group, there was a significantly higher plasma concentra?tion of free L-carnitine in treatment group after treatment [(27.00±5.69)μmol/L vs (13.20±3.04)μmol/L, P<0.05]. In treat?ment group, plasma concentration of free L-carnitine was significantly higher after treatment than that of pre-therapy [(14.87 ± 3.95)μmol/L,P<0.05]. Compared with the control group, there was a significantly lower plasma concentration of cTnI after treatment in treatment group [(0.025±0.006)μg/L vs (0.046±0.010)μg/L, P<0.05]. In the treatment group, there was a significant correlation between decreased plasma concentration of cTnI and increased plasma concentration of free L-carnitine (r=0.899, P<0.05). Conclusion Administration of L-carnitine can effectively decrease the abnormal plasma lev?el of cTnI in neonates with myocardial injury caused by asphyxia, and thereby protect the myocardium.

By Silica gel, Sephadex LH-20 and other materials for isolation and purification and by physicochemical methods and spectral analysis for structural identification, 23 compounds were isolated and identified from ethyl acetate portion of alcohol extract solution of Osmanthus fragrans fruits. Their structures were identified as nicotinamide (1), D-allitol (2), 5-hydroxymethyl-2-furancarboxaldehyde (3), acetyloleanolic acid (4), benzoic acid (5), ergosta-7,22-dien-3-one (6), beta-sitosterol (7), borreriagenin (8), cerevistero (9), c-veratroylglycol (10), methyl-2-O-beta-glucopyranosylbenzoate (11), 3', 7-dihydroxy-4'-methoxyisoflavon (12), umbelliferone (13), caffeic acid methyl ester (14), oleanolic acid (15), (-) -chicanine (16), dillapiol (17), 3beta,5alpha, 9alpha-trihydroxyergosta-7-22-dien-6-one (18), 2alpha-hydroxy-oleanolic acid (19), betulinic acid (20), betulin (21), 3, 3'-bisdemethylpinoresinol (22), and lupeol (23). All compounds were isolated from the osmanthus fruit for the first time. Except for compounds 4, 7, 15, 19, 23, the rest ones were isolated from the this plant for the first time.
