[Objective]To study the techqiue and method of using in-situ replantation of dead bone to treat infected nonunion of femur. [Method] Debridement and removal of dead bone were carried out in 2 patients who had a chunk of dead bone and multiple sinus without involucrum formation.Sterilized sequester was replanted in-situ,tibia traction was performed and continual Kawashima's irrigation was applied with sensitive antibiotic after surgery.[Result]The time of bone healing in 1 case was ten months.The patient was followed up for 42 months,there was no recurrence of osteomyelitis.The time of bone healing in another case was about 12 months,he was followed up for 30 months,there was also no recurrence in this patient.[Conclusion]Traumatic osteomyelitis complicated with a massive sequester and nonunion could be cured by process which included debridement,in-situ replantation of sterilized death bone,continual washing as well as comprehesive treatment.It could achive the two primary purposes,inflammation cure and bone healing.Among these methods,improved Kawashima's irrigation is the most important method for inflammation cure and bone union.

Objective:To observe effects of electroacupuncture at Jiaji(EX-B_2)on phosphorylated extracellular signal regulated kinase(ERK)and neurokinin-1(NK-1)in dorsal horn of the complete Freund's adjuvant arthritis rat,so as to study possible mechanism of electroacupuncture analgesia from the point of view of signal conduction.Methods:Eighty Wistar adult male rats were randomly divided into normal control group,simple electroacupuncture(EA)group,model 30 min group,model 24h group,model 48 h group,EA 30min group,EA 24h group,and EA 48h group,10 rats in each group.Inflammatory pain rat model was established by injection of complete Freund's adjuvant into left hindpaw.EA was given at bilateral L_3～L_5 Jiaji(EX-B_2).The pain threshold was determined and phosphorylated ERK and NK-1 expressions in the spinal cord were detected by immunohistochemical technique.Results:The pain threshold significantly decreased(all P

Objective:To investigate the effect of ischaemia preconditioning (IP) on function of the transplanted lungs.Methods:Rat orthotopic left lung transplantation (OLT) was performed using the cuff anastomosis technique.The rats were divided into two groups ① CONT (n=16):OLT without IP.② IP (n=15):OLT plus IP.Results:In IP group blood gas exchange and recipient survivals were significantly improved and extravascular water content decreased compared with CONT group.Conclusion:Ischaemia preconditioning not only ameliorates graft injury but inhibits graft dysfunction after OLT.

Objective To study the effects of Shen-fuinjection onthe activity of β-adrenoreceptor in SD rats with cardiopulmonary resuscitation. Method The exprimerit was done at emergency medical lab of Shanghai Changzheng hospital.Cardiac arrest was induced thngh asphyxiation(succinylcholine)and ice-cold 0.5 mol/L KCI in rats,and resuscitation began at five minutes after cardiac orrest.In this experiment,seventy-two male SD rats were randomizly divided into 9 groups:control group(sham group),routine treatment(O.5 h,2 h,4 h,6 h) groups.and Shen-fu treatment(O.5 h,2 h,4 h,6 h),and each group had 8 rats.Rats of Shen-fh treatment groups were injected with shen-fu(20 mL/kg,20 mL/h)during CPR.3H-prazosln Wag used to determine the activity of β-adrenoreceptor in myocyte. The data of the statistic analysiswere presentedin the for mofmeaj14-standard(4-5)deviation.One-way ANOVA was used for muhig Toup comparison,and t-test for comprarison between two groups.Results[3-adrenoreeeptor reached peak at0.5 h after CPR(247.81±8.91)fmol/mg,reached the lowest level at 4 h(104.17 4-13.87)fmol/mg,and returned to the normal level at 6 h(178.53±10.42)fmol/mg.In the eady period.-adrenorecepter activity in control group[O.5 h:(259.91-4-18.09)finol/mJ was similar to that in Shenfu treatment groups(P>O.05).In the late phase,adrenoreeeptor activity in the Shen-fu treatment groups[2 h:(173.04±18.77)fmol/mg,4 h:(148.72±13.88)finoL/mg]was significantly hi#er than that in the control groups(P<0.05).Conclusiom After CPR, ceplor activity firstly rises and then declines,and Shenfu injection Call significantly increase adrenoreceptor activity of mrs in the later period after CPR.

In order to improve the effectiveness of continuing medical education in military comprehensive hospital , we trans-formed the idea of continuing medical education , regulated the system , strengthened the hardware , paid more attention to the manage-ment, provided different ways for continous medical education .With the practice of continuing medical education , we should design a scientific management system and diversified activities to impove continous medical education .The article elaborated the practice of new transitional pattern of continuing medical education in our hospital in order to provide some references for the optimization of con -tinous medical education in comprehensive military hospitals .

The paper focuses on the (Primary Diagnosis at Grassroots Level,PDGL),and the current pilot situation and consequence of PDGL,analyzes the problems during the progresses,and dissects the conflicts of interest among the relative stakeholders.At last,the paper provides the corresponding countermeasures to the future development of PDGL.

Objective To explore the epidemic trend of malaria in Jinan City so as to provide the evidence for improving the prevention and control of malaria. Methods The surveillance and annual report data of malaria were collected and analyzed epidemiologically in Jinan City from 1989 to 2013. Results The prevalence of malaria was low in Jinan City from 1989 to 2013. Totally 179 cases of malaria were reported and 14 cases 7.82% were locally infected and 165 cases 92.18% were imported. Conclusion Most malaria cases were imported since the disease was basically eliminated in Jinan City. The overseas workers from high prevalence areas of malaria should be well managed.

AIM:To study the parameters of supercritical CO_2 extraction of essential oil from valeriana efficinalis by orthogonal design. METHODS: Four factors,such as extraction pressure,extraction temperature,extraction time and separation temperature were chosen by the observation of orthogonal design,each factor was assigned to three levels.Bornyl acetate content was selected as a marker in a position to determine optimal extraction. RESULTS: Pressure and temperature were the main factors in effecting the extraction of bornyl acetate,extraction time was minor factor relatively. CONCLUSION: The optimal extraction is as follow,parameters were extraction pressure:12 MPa,extraction temperature:45 ℃,extraction time:1 hour,separation temperature:35 ℃,it gave the best recoveries of essential oils and bornylacetate.
