ObjectiveTo investigate the clinical efficacy of points injection of mouse nerve growth factor in treating sciatic nerve injury.MethodAcupuncture point injection of injectable mouse nerve growth factorwas performed in 60 patients with sciatic nerve injury. Points Huantiao(GB30)and Zusanli(ST36)were selected. Treatment was given once daily, for a total of 30 times. Sensory and motor functions were assessed (MS and SS) and electromyography (EMG) was performed before and after treatment to compare motor nerve conduction velocities (MCV) and sensory nerve conduction velocities (SCV) in the injured nerves and EMG changes in the musclescontrolled by the injured nerves.ResultAfter treatment, nerve function was restored to more than S3M3, with an efficacy rate of 81.7%, in 49 patients. Neuro-electrophysiological study showed that regenerative potentials occurred, accounting for 71.7%,in43patients. Denervated potentials were fewer after treatment than before; there was a significant difference (P<0.05). The mean MCV value increased after treatment compared with before; there was a significant difference (P<0.05). ConclusionAcupuncture point injection of mouse nerve growth factor can markedly improve sensory and motor functions in the regions controlled by the injured sciatic nerve. It provides an effective way to promote the repair of sciatic nerves and the reconstruction of limb function after the nerves are injured.

Objective To investigate the changes of cholesterol efflux,the scavenger receptor class B type Ⅰ(SR-BI) protein expression in THP-1 maerophage derived foam cells treated with Lippolysaecharide (LPS), and to discover the role of NF-κB pathway in this process.Methods The foam cells were treated with LPS along or treated with N-p-Tosyl-L-phenylalanine chloromethyl ketone(TPCK) for 24 h.The protein levels of SR-BI and intranuclear NF-κB p65 were measured by Western blotting.Cellular lipid accumulation was determined by high performance liquid ehromatograpby analysis.Cholesterol efflux was determined by FJ-2107P type liquid scintillator.Results The expression of SR-BI was decreased after treated with LPS,while the intranuclear NF-κB p65 protein level was increased by LPS.The results also showed that cellular lipid accumulation was increased ,while the cellular cholesterol efflux was decreased in THP-1 maerophage derived foam cells after exposed to LPS for 24 h and these changes can be reversed partly by pretreatment with TPCK.Conclusion LPS could down-regulate the expression of SR-BI, promote the accumulation of lipid and decrease cellular cholesterol efflux in THP-1 maerophage derived foam cells ,which should be related to the TLR4/NF-κB dependent pathway.

OBJECTIVE:To systematically review the efficacy and safety of Moxifloxacin(MFX)in the treatment of acute ex-acerbation of chronic bronchitis (AECB),and provide evidence-based reference for Tational use of MFX. METHODS:Retrieved from PubMed,EMBase,Cochrane Library,Medline,CBM,CJFD,VIP and Wanfang Database,the relevant conference proceed-ings and grey literature were also hand-searched,randomized controlled trials(RCT)about MFX(test group)versus other antibiot-ics (control group) in the treatment of AECB were collected. Meta-analysis was performed by using Rev Man 5.2 software with ITT analysis and PP analysis after literature selection,data extraction and quality evaluation. RESULTS:Totally 14 RCTs were in-cluded,involving 6 058 patients. Results of PP analysis showed,the clinical effective rate in test group was similar to that of con-trol group [RR=1.02,95%CI(1.00,1.04),P=0.06],while bacteria clearance rate was significantly higher than control group [RR=1.07,95%CI(1.04,1.11),P<0.001]. Results of ITT analysis showed,the clinical effective rate in test group was significantly high-er than control group [RR=1.03,95%CI(1.00,1.06),P=0.03],while there was no significant difference in the bacteria clearance rate [RR=1.02,95%CI(0.92,1.12),P=0.73] and the incidence of adverse reactions [RR=0.97,95%CI(0.87,1.08),P=0.52] be-tween 2 groups. CONCLUSIONS:The efficacy of MFX is not inferior to other antibiotics in the treatment of AECB,safety is simi-lar to other antibiotics.

OBJECTIVE:To explore the feasibility of using international index of rational drug use for the intervention and evaluation of rational use of antimicrobial agents during perioperative period in patients undergoing thyreoidectiomy.METHODS:The patients in the common surgical department were divided into intervention group and non-intervention group.An intervention control study was performed before intervention(from Mar.to Aug.in 2007)vs.after intervention(from Mar.to Aug.in 2008)on the synchronously discharged thyreoidectomy patients with the international index of rational drug use as references.RESULTS:After prophylactic use of antibiotics in the intervention group,the average antimicrobial application time was decreased from 6.83 days to 2.50 days,the average hospital stay of patients was decreased from 8.24 days to 7.15 days,the average hospitalization fee decreased from 1 895.99 yuan to 1 375.26 yuan,the cost of antibacterials decreased from 852.11 yuan to 538.53 yuan,and the proportion of the cost of antibacterials in the total hospitalization cost reduced slightly.However,all the indexes in the non-intervention group showed little change.CONCLUSION:It is effective and feasible to adopt the international index of rational drug use in the intervention and evaluation of rational use of antimicrobial agents during perioperative period.

Objective:To purify and characterize the major antigenic components of sand swimming crab,and provide theoretical evidences for the research of standardization of allergenic vaccine.Methods:The crude extract of Linnaeus was prepared using classical method, and electrophoresis of SDS-PAGE was used to separate the proteins of each group. The allergen proteins of 26 crab were identified using Western blot. To distinguish between the primary allergen proteins and secondary allergen proteins, FPLC(Gel Chromatography and ion exchange chromatography) was used to filtrate and identify the allergen protein.Results:SDS-PAGE analysis revealed that sand swimming crab proteins were composed of at lease 9 discrete protein bands, which molecular weight ranging from 13 000 to 90 000. Major bands were of 20 900, 24 200, 27 100, 29 200, 33 700, 38 900, 48 700, 74 700, 89 100 respectively. Western blot assay indicated that the crude extract reacted with sera obtained from 26 crab allergenic subjects and contained 5 allergen bands altogether, and the bands of 74 400 and 48 700 were the major allergenic components. The positive rates of the two major allergen proteins were both 100%, indicating the allergenic components maintained the immunocompetence after yielding from chromatography.Conclusion:The 74 400 and 48 700 bands are the major allergens of sand swimming crab. The major allergen proteins can be purified by chromatography.
