Septic arthritis of the sternoclavicular joint(SCJ) is a rare condition and accounts for 0.5％-1.0％ of septic arthritis.SCJ infections often require surgical intervention.Diabetes mellitus,rheumatoid arthritis,intravenous drug use,intraarticular injection and immunosuppressive disorders are predisposing factors.Staphylococcus aureus and Pseudomonas aeruginosa are the most common bacteriologies.Early diagnosis of SCJ infection requires a high index of suspicion and a confirmatory CT or MRI scan.The characteristic imaging features include intramedullary and soft tissue gas,sequestra,soft tissue swelling and destruction or widening of joint space.Management strategies have ranged from conservative antibiotic therapy to en-bloc resection of the sternoclavicular joint with or without ipsilateral pectoralis major muscle transposition.The shoulder function in most patients were well preserved.

Objective To explore the effect of cutaneous never anastomosis on sensory recovery in repairing wide spreadly soft tissue defects in dorsal hand with free anterolateral femoral flap. Methods The cases with wide spreadly soft tissue defects in dorsal hand repaired with free anterolateral femoral flap from January 2006 to December 2012 were divided into 2 groups. The control group including 15 consecutive patients from January 2006 to January 2009, whose sensation was reconstructed in routine way. Other 15 consecutive patients from Febnary 2009 to December 2012 were as research group, whose sensation was reconstructed with the suture of cutaneous nevers of anterolateral femoral flaps and forearm. All the patients were followed up for 12~24 months. Results All the free flaps survived in both groups. There were 4 cases good of sensory recovery in the control group, and it was 11 in the research group. No ulceration happened. Conclusion Cutaneous never anastomosis may result in satisfactory sensory function in the patients with wide spreadly soft tissue descts in dorsal hand repaired with free anterolateral femoral flap.

Five flavone C-glycosides were isolated from the methanol extract of the degrease seeds of Ziziphus jujuba var. spinosa though various column chromatography methods including silica gel, MPLC, and HPLC. The structures were elucidated as 6"-feruloyl- 6'''-vanillylspinosin(1), 6",6'"-diferuloylspinosin(2), spinosin(3), swertisin(4) and isoswertisin(5) based on the NMR and MS spectral data. 1 is a new compound.

Aim To investigate the protective effects of nicorandil, glutamine and metoprolol used in single and combination on the antiapoptosis ability of cardio-cytes and the expression of HSP70 after myocardial is-chemia/reperfusion injury in rats. Methods Male Wistar rats were divided randomly into seven groups:( 1 ) Sham group:in which the coronary artery was not roped;(2) I/R group:in which only 30 min ischemia and 120 min reperfusion of LAD was executed; ( 3 ) Nicorandil group; ( 4 ) Glutamine group; ( 5 ) Meto-prolol group; ( 6 ) Nic + Glu + Met ( NGM ) group;(7) low dose of Nic+Glu+Met ( NGML) group. In the pharmacological precondition groups, correspond-ing drugs were administered 30 min before I/R proto-col, and the initial drug dose in each group was 1 mg ·kg-1 . Myocardial apoptotic rates were measured with TUNEL ( terminal dexynucleotidyl transferase-mediated dUTP nick end labeling) , and the expression of apop-tosis related proteins-Bcl-2/Bax and protective pro-tein-HSP70 was detected by Western blot. ResultsIn I/R group, the apoptotic rate in ischemic region was very high ( 36.9% ± 10.3%) , and Bcl-2/Bax was very low ( 0.14 ±0.08 ) . Compared with I/R group, the apoptotic rate of pharmacological precondition groups was decreased significantly ( P <0.01 ) , and the ratio of Bcl-2 to Bax was raised ( P<0.01 ) . Com-pared with Sham group, the expression of HSP70 in-creased significantly ( P<0.01 ) in I/R group. Com-pared with IR group, the expression of HSP70 of phar-macological precondition groups was elevated ( P <0.01 ) , and the expression in NGM group was higher than in the single drug group ( P<0.01 ) . Conclusion Compared with single therapy after I/R in rat, the combination therapy of nicorandil, glutamine, meto-prolol can decrease the apoptotic rate, and the expres-sion of apoptosis related proteins is developed. In the mean time, the expression of protective protein HSP70 is elevated.

Ginkgo is one of the most successful cases of botanical drugs developed by modern science and technology during the past fifty years all over the world. At present ginkgo has been applied to the prevention and treatment of cardiovascular disease widely, and has good clinical efficacy. Type 2 diabetes has been proved to be the risk equivalents of cardiovascular disease, therefore it has an important scientific significance for looking for more effective drugs of prevention and control of diabetes. To seek more efficient and safe drug from the plant medicine which has the function of regulate blood sugar and improve insulin resistance becomes a hotspot at home and abroad. Basic and clinical studies have shown the ginkgo preparations of Chinese medicine have certain regulation effect on blood sugar and insulin resistance. In this paper, we review the mechanisms and clinical applications of ginkgo preparations on diabetes and its applications during the past 10 years.

Objective To investigate the protective effects of CBD and Nimodipine against injuries secondary to glutamate-inuced or traumatic injury in rat cortical neurons in vitro. Methods Mix-cultured cortical neurons of SD rat were subjected to either glutamate injury or mechanical damage. The degree of injury were detected by cell count of trypan blue staining and measurement of lactate dehydrogenase (LDH) activity in the culture medium. Results When combined treatment with CBD and Nimodipine was used separately, moderate protective effects against the injury of cultured cortical neurons induced by glutamate or trauma were observed, which was obvious when compared with the injured group without treatment (P<0.01). When combined treatment with CBD and Nimodipine was administered, strong protective effect were observed than that with treatment using CBD or Nimodipine alone (P<0.01). Conclusion It is suggested that CBD combined with Nimodipine are synergetic. Combined use of different excitotoxic antagonists can be fruitful in the therapeutic intervention of secondary traumatic damage.
