Objective To explore the optimal screw fixation of anterior column lag screw fixation in the treatment of acetabular anterior column fractures by finite element method.Methods Firstly,CT scanning images from one healthy adult volunteer (male 30),were transferred into Materialise Mimics Innovation Suite 16.0 software,then three-dimensional (3D) models of pelvic were reconstructed and stored in stereolithography format.Then Imageware 12.0 software (EDS,USA) was used to produce the optimal and safe channel of the screw for acetabulum anterior column fixation.Three types of screw fixation were generated,i.e.(1) geometric algorithm screw channel,(2) in-out-in channel,(3) free screw channel.Secondly,all model data were transferred into Ansys 12.0 software to establish the finite element model.Gravity load were defined as 600 N,1 200 N,and 2 400 N,and the Von Mises the parameters of peak stress and deformation were recorded.Results Respectively load of 600 N,1 200 N,2 400 N force to normal hip and geometric algorithm screw channel, in-out-inscrew channel,free screw channel,the comparison between groups of hip by stress and hip deformation,with a given loading force of hip by stress and hip deformation increase gradually,the two were positively correlated,including screw by stress at slightly higher than that of normal hip,while the stress of hip by geometric algorithm screw channel andin-out-inscrew channel were similar,and that by free screw channel increased significantly.There was no significant difference between groups in the hip deformation.With a given loading force (600 N,1 200 N,2 400 N) on geometric algorithm screw channel、 in-out-inscrew channel and free screw channel,the deformation is gradually increased,and there were positively correlated.With the stress on geometric algorithm screw channel,it was significantly reduced compared with the latter two,and in-out-in screw channel suffered the biggest stress.Conclusion Through the finite element analysis,the geometric algorithm screw channel can be used as a safe and effective way for acetabulum anterior column fracture.

Objective: To investigate the antimotion sickness effects of ginsenosides combined with dexamethasone in rats. Methods: Fifty SD rats were randomly divided into 5 groups: normal saline, scopolamine-treated, ginsenosides-treated, dexamethasone-treated and ginsenosides plus dexamethasone-treated groups. There were 10 rats in each group. The rats in each group were fed with corresponding ingredients respectively, and then the rats were exposed to abnormal acceleration for one hour. The motion sickness index, the level of kaolin consumption and the course and time of spontaneous activity were observed. Results: The motion sickness index and the level of kaolin consumption of acceleration-exposed rats in ginsenosides plus dexamethasone-treated group were significantly lower than those in normal saline group. And the course and time of spontaneous activity of acceleration-exposed rats in ginsenosides plus dexamethasone-treated group were significantly higher than those in normal saline group. The level of body weight increment of acceleration-exposed rats in ginsenosides plus dexamethasone-treated group was significantly higher than that in dexamethasone-treated group. Conclusion: Ginsenosides combined with dexamethasone can significantly increase tolerance to acceleration of rats, and the drug combination can decrease side effects of methylprednisolone, such as body weight loss.

Objective To investigate the clinical significance and relationship of preS1, HBV DNA and HBV-M. Methods PreS1 and HBV-M was detected by ELISA method,and HBV DNA was detected by PCR. Then the results were analyzed. Results In HBV patients,the positive rates of preS1 and HBV DNA had no statistically significant ,they had fine dependability. The detection rate of preS1 in HBeAg(+) group(80.3%) and HBeAg(+)group( 56.3% ) had statistically significant. In some patients,though HBeAg had become negative, HBV still replicated. In HBV DNA replicated patients(≥103 copies/ml) ,the detection rate of HBeAg and preS1 were 51.5% and 70.9% ,they had statistically significant. Conclusion HBV DNA and PreS1 had fine dependability,preSl could reflect the replication of HBV sensitively than HBeAg,it could be used as a reliable new marker of HBV replication in vivo.

Objective To investigate the correlation between serum tumor markers levels with the disease condition activity and the tumor occurrence in the patients with rheumatoid arthritis(RA).Methods Serum tumor marker CA199,CA153 levels were de-tected in 35 patients with RA (RA group)and 31 healthy controls(normal control group).ESR and CRP were examined and the disease activity (DA)was assessed by the DAS28 score in the RA group.The serum tumor markers levels and the positive rates were compared between the RA group and the normal control group.The correlation between the serum tumor markers levels with ESR,CRP and DAS28 score was analyzed.Results Serum levels and positives rate of CA199,CA153 in the RA group were higher than those in the control group(P <0.05).The serum CA153 level had a positive correlation with the ESR,CRP and DAS28 score in the RA group(P <0.05),but the serum CA199 level had no significant correlation with them.Conclusion The serum levels and positive rates of CA199 and CA199 could be increased in the patients with RA,moreover the increase of serum CA153 level is corre-lated with DA of RA.Therefore the serum tumor marker CA153 level may be used as one of reference indexes for evaluating the DA in the patients with RA.

Objective To summarize the MSCT signs and the key points of differential diagnosis of sclerosing mesenteritises (SM) which were misdiagnosed by clinical and CT,to reduce the misdiagnosis rate.Methods Clinical and MSCT data of 23 misdiagnosed SM patients were analyzed retrospectively.The misdiagnosed diseases,misdiagnosed causes,and differential diagnosis were analyzed.Results SM were mainly misdiagnosed as tumor and infective inflammation.The main causes of misdiagnosis and differential diagnostic features were listed as follows.(1)SM didn't have specific clinical manifestations.(2)The density of the adipose tissue in mesentery increasedmisty mesentery.A clear demarcation between the lesion and the surrounding normal fatty tissue could be differentiated from infective inflammation.(3)The mass-like false capsule had space-occupying effect of displacement of the surrounding structures.However, the blood vessels were encapsulated by the mass-like false capsule with fat ring around, which could be differentiated from fat-containing tumors.(4)The soft mass was formed at the root of the mesentery.The fat halo sign and mild enhancement of the mass can be differentiated from lymphoma and carcinoid.Conclusion SM is easily misdiagnosed both in clinical practice and medical imaging.Recognition of differential diagnostic features of MSCT can reduce the misdiagnosis rate.
