Resident doctor standardization training is the base of dermatologist training. We set up the specialist standardization training system according to our hospital's training practice. The dermatolo-gist standardization training mode was set up through tutor responsibility rule , internet learning platform and problem-based learning methods. The teaching level for dermatologists was upgraded by using above methods.

Objective:To investigate the impact of recombinant flagellin targeting TLR5 and NLRC4 simultaneously or respectively on innate immune cells in mice. Methods: Induction,expression,purification and identification of recombiant FliC,which were FliC(activating both TLR5 and NLRC4);FliCΔ90-97(unable to activate TLR5),FliC-L3A(unable to activate NLRC4),FliCΔ90-97:L3A(unable to activate both TLR5 and NLRC4). The mice were divided into five groups,namely group FliC,FliC-L3A,FliCΔ90-97,FliCΔ90-97:L3A and PBS,which were injected with 100μl PBS or 10μg recombinant flagellin intraperitoneally,three mice in each group. 12 h later,the mice were executed using dislocation of cervical vertebra and the splenic and peritoneal cells were isolated. The spleen was grinded into single-cell suspension. The proportion of neutrophils,NK cells,DCs and the expression level of CD80 and CD86 on DCs were evaluated with flow cytometry. Results:Group FliC,group FliC-L3A and group FliCΔ90-97 shared the similar proportion of neutrophils in peritoneal cavity ( P>0. 05 ) , and all of which were significantly higher than group PBS and group FliCΔ90-97 ( P<0. 01),and NK cells also showed the similar trend. Compared with group FliCΔ90-97 and FliCΔ90-97:L3A,the mean fluorescence intensities(MFIs) of CD80 and CD86 in group FliC and FliC-L3A increased significantly(P<0. 01). The proportion of Treg in spleen was highest among all groups. Conclusion:Activation of TLR5 and NLRC4 had similar chemotaxis of neutrophils and NK cells. The ex-pression of CD80 and CD86 on DCs were upregulated after stimulation by flagellin and TLR5-dependent. Activation of TLR5,but not NLRC4,increased the proportion of Treg in spleen.

Objective:To develop an HPLC method for the determination of capsaicine, dihydrocapsaicin, imperatorin and isoim-peratorin in Guanjie Jietong plasters. Methods:A CAPCELL PAK C18 column was used as the chromatographic column, and the flow rate was 0. 8 ml·min-1. The mobile phase A consisted of methanol-acetonitrile(1∶1), the mobile phase B was of 1% phosphoric acid. The detection wavelength was 280 nm and 254 nm, respectively. Results:There was a good linear relationship between the con-centrations and the peak areas within the range of 0. 298-5. 956μg(r=0. 9998) for capsaicine, 0. 152-3. 044μg(r=0. 999 6) for di-hydrocapsaicin, 0. 018-0. 352 μg(r=0. 999 5) for imperatorin and 0. 010-0. 204 μg(r=0. 999 3) for isoimperatorin. The average re-covery was 97. 8%(RSD=1. 02%), 97. 0%(RSD=0. 76%), 96. 6%(RSD=0. 65%) and 98. 1%(RSD=1. 35%), respectively. Conclusion:The method is convenient, accurate, sensitive and repeatable, which can be used in the determination of capsaicine, di-hydrocapsaicin, imperatorin and isoimperatorin in Guanjie Jietong plasters.

OBJECTIVE:To improve the preparation of compound menthol spray and study its stability.METHODS:The liquor compound menthol spray was changed to emulsified ones by the solubilizing action of tween80.The stability of emulsified compound menthol spray(ECMS)was observed in airtight container at room temperature(25?2)℃.RESULTS:ECMS was stable within2wks in airtight container at room temperature.CONCLUSION:ECMS is stable in property,convenient in stor?age,and accords with pharmaceutical quality standards.

0.05).However,the level of PRG-1 protein in cerebral cortex of experimental group was significantly higher than that of control group at 7 d(t=2.347,P=0.041).Conclusion The up-regulated expression of PRG-1 in cerebral cortex may be associated with the recurrent neonatal seizure-induced brain damage.

Objective To study a feasible technology plan for information communication between doctors and patients.Methods Based on three-layer B/W/S and Windows2003 Server,MS SQL Server was used for database administration.The Apache Tomcat 5.5 was adopted as Web server and Web services were realized by using JSP(Java Server Page).Results Health care information was collected and integrated in medical information platform of clinical department which was connected into Internet directly.The information platform established communication way between doctors and patients and it had functions for chief complaint,diagnosis,reservation and revisit.Conclusion Communication between doctors and patients are realized.

Objective To investigate the effects of celastrol on the expressions of macrophage migration inhibitory factor(MIF)and matrix metalloproteinase-9(MMP-9)in the aorta of apoE gene knockout mice with earlier atherosclerosis.Methods Eight-week-old ApoE gene knockout male mice were divided randomly into control group and celastrol treatment group(n=6 in each group).The mice in celastrol group were given.celastrol(2 mg?kg-1?d-1)by intraperitoneal injection for 4 weeks;and the mice in control group were only given equivalent amount of dimethyl sulfoxide(DMSO).HE staining of root aorta were used to observe the histomorphological changes and measure the size of plaque in ApoE-/-mice.The expressions of MIF and MMP-9 were detected by immunological histochemical method.Results The area of lipid plaque in the mice treated with celastrol was significantly smaller than that of the control(P

The battlefield rescuing unit of the current model is always restricted by some factors such as regional environments in wartime rescuing action and peacetime disaster relief, which can lead to failure of following and deploying action, so that wounded persons can not be rescued at the first time. Aiming at the special circumstances, a forward first-aid unit composed of five doctors and nurses should be established to give emergency medical rescue with rescuing emergent equipments and medicine packed in portable packages such as portable respiring machine, defibrillator and oxygen device at the battlefront. In this way, success rate of rescuing wounded persons would be increased obviously, while mortality rate and deformity rate would be decreased greatly.

Objective To investigate the effects of liver X receptor agonist on the expressions of C-reactive protein and CD40 ligand and smooth muscle cell ?-actin in the aorta of ApoE gene knockout mice with earlier atherosclerosis. Methods Male ApoE gene knockout mice (8-week old) were divided randomly into control group and T0901317 treatment group (n=6 in each group). The mice in T0901317 group were administered intraperitoneally with T0901317 at the dose of 20 mg?kg-1?d-1 for 4 weeks. Mice in the control group were only given equivalent amount of dimethyl sulfoxide (DMSO). The expressions of C-reactive protein and CD40 ligand and smooth muscle cell ?-actin were detected by immunological histochemical method. Results The expressions of C-reactive protein and CD40 ligand in the atherosclerotic plaque in the aortic wall were significantly lower in T0901317 group as compared with those in the DMSO control group (P0.05). Conclusion Liver X receptor agonist may reduce the formation of atherosclerotic lesions by inhibiting the inflammation and the expressions of C-reactive protein and CD40 ligand in the aorta of ApoE gene knockout mice.

100 U/ml and treated for 48 h,the inhibitory ratio of the HepG2 cells was raised to (39.08?2.32)%,which were not further elevated with the increase of dose or elapse of treatment time. HepG2 cells apoptosis was induced by thrombin.in a dose-and time-dependent manner when the dose was between 25 to 100 U/ml. However,there was no significant difference in the apoptosis of different groups when the dose was higher than 100 U/ml and the time exceed 48 h. Conclusion Higher doses of thrombin can inhibit the proliferation of HepG2 cells,and lead to cell apoptosis. The both effects are increased in a dose-and time-dependent manner when the dose is
