Objective To observe the antibacterial activity of artificial antimicrobial peptides (AMPs) to Blastomyces albicans, E. coli and Staphylococcus aureus in oral infection in vitro. Methods The AMPs were dissolved into PBS or sterilized saliva, then the inhibi-tion of different concentration AMPs to E. coil was evaluated by tube testing. The inhibition effect of different concentration of AMPs to Staph-ylococcus aureus and Blastomyces albicans were evaluated by antibiotic-susceptive test paper. Results When the concentration of AMPs added to broth of E. coli is from 150μmol/L to 300μmol/L , the bacterium count is 0 while the number in control is 6700 ～ 9200cfu/ml. At 100μg/tablet AMPs, the diameter of inhibitor zones of Staphylococcus aureus and Blastomyces albicans are 13mm and 11 mm. At 300μg/ tablet, the diameter are 16 mm and 17mm. AMPs dissolved in PBS and saliva have similar antimicrobial activity. Gonclusions The AMPs is effective to prevent Blastomyces albicans, E. coli and Staphylococcus aurcus in oral infection in vitro.

[Objective]To introduce a new technique of ankle arthrodesis with trephine by lateral approach and evaluate its clinical effects.[Method]Ankle arthrodesis with trephine was performed in 20 patients with serious lesions.Lateral incision was adopted and osteotomy of fibula facilitated the exposure of the fusion site.A trephine of appropriate diameter was used for bi-osteotomy,thus inside the trephine gaining two bone blocks were then rotated 90? and replanted in situ.The pruned fibula was fixed with screws as on-lay!grafting.Proper cast was utilized postoperatively to maintain a functional position.[Result]The average follow-up period was 26 months(ranged from 6 months to 4 years).All the wounds healed well at 2 weeks and the callus appeared 4 weeks postoperatively.Sufficient pain relief was obtained in all patients at 12 weeks and appearance improved greatly.A solid union was achieved in all cases through the radiograph.[Conclusion]The use of trephine in ankle fusion by lateral approach is proved to be a simple technique with high union rate.The main advantages of the technique over other methods of arthrodesis include: excellent exposure by regular incision;less disturbance of the original joint,thereby preserving normal height of the joint and length of the extremity;no need for extra graft through in-situ grafting of the bone blocks and rigid on-lay grafting of lateral malleolus for high primary stability.

Objective To observe and analyse the application effect and value of problem based learning (PBL) combined evidence-based learning (EBL) in emergency medicine clinical teaching.Methods A total of 53 clinical medicine students were selected.The combined teaching method was applied in emergency clinical teaching.After the end of the teaching,the teaching effectiveness survey and theory test of the combined teaching group was performed,and the theory test scores was compared with the traditional teaching group.Results The combined teaching method could stimulate learning enthusiasm,improve learning efficiency,the abilities of selfstudy,literature retrieval,and the ability to analyze and solve problems.77.4％ of students thought this new teaching method had good application value in clinical teaching.Furthermore,the excellent rate of the theory test scores combined teaching group was better than traditional teaching group (41.5％ vs 15.6％,x2 =7.868,P =0.007).Conclusions The PBL joint EBL pedagogy can overcome diadvantages of tradional teaching and provide higher interest,ability of self-study as well as higher teaching quality of the medical students.It will be worth to spread in medical clinical teaching.

Objective To investigate the significance of I?B kinase-?(IKK-?) and the protective effect of Ligustrazini(Lig) in acute lung injury(ALI) induced by hemorrhagic shock(HS) in rabbits. Methods Thirty rabbits were randomly divided into three groups: HS plus endotoxin group(n=10), Lig treatment group(n=10) and the normal group(n=10). In situ hybridization and immunohitochemistry combined with in situ quantitative analysis were used to detect the distribution and relative contents of IKK-? and NF-?B in lung tissues. The plasma concentration of tumor necrosis factor-?(TNF-?) was measured by ELISA. Morphological change of the lung was observed by light microscopy. Results Compared with the normal group, the expression levels of IKK-?(0.223?0.080), NF-?B(0.162?0.021), and TNF-?(809.33?201.6) were obviously increased in HS plus endotoxin group(P

Inheirted metabolic disodrers(IMD)involves in multiple substance dysbolism,which usually results in irreversible neurological lesions because of various categories and complicated clinical manifestations.In resent years,IMD became one of the hot spots in medical domain around the world,original diagnostic technique and management progressed unceasingly.This paper provides an overview of the traditio-nal detection and treatment about IMD,and reviews the new techniques such as gene analysis,gene chip,organ transplantation and enzyme replacement therapy at the same time.

Traumatic coagulopathy is a serious complication of tissue damage caused by trauma.In clinic,it easily develops into multiple system organ failure and results in high mortality.Traumatic coagulopathy is a plurality of blood coagulation disorder,its pathogenesis is extremely complex and involves tissue damage,blood coagulation,anticoagulation and fibrinolysis,inflammation and many other pathophysiological aspects.An in-depth study on the pathogenesis of traumatic coagulopathy is very important to improve clinical effect.This paper tries to do a review of recent study progress from pathophysiological mechanisms and hopes to provide reference for clinical work.

OBJECTIVE:To analysis the volatile components in wild strains of Rabdosia rubescensin in Jiyuan area. METH-ODS:Headspace solid phase microextraction (HS-SPME) was conducted to extract the volatile components in 43 wild species of R. rubescens,GC-MS was conducted to identify the components,and peak area normalization method was conducted to calculate the relative content of the components. RESULTS:The variety and relative contents of the volatility components in 43 wild species had obvious differences and the ranges of species number and relative content was from 0 to 11 and from 0 to 84.03% respectively. Caryophyllene,caryophyllene oxide,dihydroactinidiolide,phytone and patchouli alcohol were main components which existed in a variety of different strains of volatile components of R. rubescens,and were mainly composed of terpenes,ketones,alcohols and es-ters. In addition,fatty acids such as palmitic acid,oleic acid and linoleic acid were contained in a few individual varieties. CON-CLUSIONS:The internal quality in 43 wild species of R. rubescens has certain differences.
