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 analysis the etiology and molecular classification of brucella strains isolated in Guangdong province in 2010.Methods The strains of 19 brucella were verified and identified by some methods including traditional biology phenotype confirmation,PCR amplification and pulsed field gel electrophoresis (PFGE).Results On phenotype level,4 strains were brucella melitensis biovar 1,2 strains were brucella suis biovar 3,and the rest were brucella melitensis biovar 3,which were specific B genes positive strains,and the PFGE typing similar values ranging from 67.9％ to 100％.In addition to the four strains from Zhuhai for the outbreak,the homology was 100％,and the rest were sporadic cases.Conclusions Brucella cases,in Guangdong province,are highly sporadic and dispersed outbreaks.Compared with a few years ago,it shows species diversification,and brucella melitensis biovar 3 is still the dominant serotype.PFGE can be used to distinguish the three species of brucella,but it can't effectively distinguish the allotypes.

BACKGROUNDNon-valvular atrial fibrillation is associated with an increased risk of ischemic stroke; however, the appropriate intensity of anticoagulation therapy for Chinese patients has not been determined. The purpose of this study was to compare the safety and the efficacy of standard-intensity warfarin therapy, low-intensity warfarin therapy, and aspirin therapy for the prevention of ischemic events in Chinese patients with non-valvular atrial fibrillation (NVAF).

METHODSA total of 786 patients from 75 Chinese hospitals were enrolled in this study and randomized into three therapy groups: standard-intensity warfarin (international normalized ratio (INR) 2.1 to 2.5) group, low-intensity warfarin (INR 1.6 to 2.0) group and aspirin (200 mg per day) group. All patients were evaluated by physicians at 1, 3, 6, 9, 12, 15, 18, 21 and 24 months after randomization to obtain a patient questionnaire, physical examination and related laboratory tests.

RESULTSThe annual event rates of ischemic stroke, transient ischemic attack (TIA) or systemic thromboembolism were 2.6%, 3.1% and 6.9% in the standard-intensity warfarin, low-intensity warfarin and aspirin groups, respectively (P = 0.027). Thromboembolic event rates in both warfarin groups were significantly lower than that in the aspirin group (P = 0.018, P = 0.044), and there was no significant difference between the two warfarin groups. Severe hemorrhagic events occurred in 15 patients, 7 (2.6%) in the standard-intensity warfarin group, 7 (2.4%) in the low-intensity warfarin group and 1 (0.4%) in the aspirin group. The severe hemorrhagic event rates in the warfarin groups were higher than that in the aspirin group, but the difference did not reach statistical significance (P = 0.101). The mild hemorrhagic and total hemorrhagic event rates in the warfarin groups (whether in the standard-intensity warfarin group or low-intensity warfarin group) were much higher than that in the aspirin group with the annual event rates of total hemorrhages of 10.2%, 7.6% and 2.2%, respectively, in the 3 groups (P = 0.001). Furthermore, there was no significant difference in all cause mortality among the three study groups.

CONCLUSIONIn Chinese patients with NVAF, the warfarin therapy (INR 1.6 - 2.5) for the prevention of thromboembolic events was superior to aspirin.
