Objective:To investigate an effective paradigm to test false belief understanding for the Autism. Method:By comparing the multimedia animation presentation and the traditional presentation, 20 autistic children's false belief understanding was analyzed as well as the normal children's.Results:Animation presentation was really helpful to both groups, especially for the children with autism. The performance might be underestimated due to the application of the traditional presentation in false belief tasks.Conclusion:The autistic children's theory of mind can be measured much closer to the truth if the more apt tasks are considered.

Objective To compare curative effects between laparoscopic oviduct-sparing operation and medical interventional treatment for the management of tubal pregnancy.Methods A total of 63 patients with tubal pregnancy were randomly divided into two groups.One group underwent laparoscopic salpingotomy and aspiration of the gestational sac content, while the other group underwent intra-tubal injection of methotrexate(MTX).Curative effects of the two procedures were compared.Results Laparoscopic oviduct-sparing operation was successfully performed on one session in 31 out of 32 patients,the success rate being 96.9%.Medical interventional treatment was conducted successfully in 24 out of 31 patients,23 of whom received one dose of MTX and 1 of whom received two doses,the success rate being 77.4%.There was no statistical difference between the two groups in success rates (?~2=3.765,P=0.052).The time for serum ?-hCG to normal levels was significantly shorter in patients receiving laparoscopic oviduct-sparing operation(9.1?2.1 d) than in patients receiving interventional treatment(26.3?3.9 d)(t=-20.974,P=0.000).Conclusions Both laparoscopic oviduct-sparing operation and medical interventional treatment can effectively preserve affected oviduct for patients with tubal pregnancy.As compared with medical interventional treatment,laparoscopic oviduct-sparing operation has a broader range of indications,less side effects,and a shorter recovery time of serum ?-hCG.

AIM To express recombinant human cytochrome P450 3A4 mutants CYP3A4.3, CYP3A4.4, CYP3A4.5 and CYP3A4.18, and to employ them for in vitro metabolism studies of CYP3A4. METHODS Use Bac-to-Bac baculovirus expression system to recombinant baculovirus carrying cDNA of CYP3A4 mutants CYP3A4.3, CYP3A4.4, CYP3A4.5 and CYP3A4.18. Spodoptera frugiperda 9 (Sf9), cells were co-infected by recombinant viruses of CYP3A4 mutants, human NADPH-P450 oxidoreductase and cytochrome b5 to obtain recombinant proteins CYP3A4.3, CYP3A4.4, CYP3A4.5 and CYP3A4.18 with metabolic activity. RESULTS The mRNA transcription of CYP3A4 mutants in Sf9 cells were validated by RT-PCR. Testosterone and 7-benzyloxy-4-(trifluoromethyl) coumarin were metabolized by the lysates of Sf9 cells infected by the recombinant viruses. CONCLUSION CYP3A4 mutants CYP3A4.3, CYP3A4.4, CYP3A4.5 and CYP3A4.18 with metabolic activity were successfully expressed by baculovirus-insect cell expression system. The results indicated that recombinant CYP3A4. 5 showed lower activity comparing to the wild type protein towards testosterone, while CYP3A4. 18 with higher activity, and for CYP3A4.3 and CYP3A4.4 showing similar activity to the wild type protein.

Primary biliary cirrhosis(PBC) is a chronic,progressive cholestatic liver disease of unknown cause that usually affects middle-aged women.Ursodeoxycholic acid(UDCA)is the first selected drug to PBC which has definite effect.Treament of PBC with UDCA combined with immunodepressant become presents research focuses.Liver transplantation is the only treatment of the final stage of PBC.

Objective:In occurrence and development process oflung cancer, the only known angiogenesis is one element ofthe growth, proliferation and aversion oftumor cells.VEGF, MMP-2 and MMP-9 play important role in the development and aversion ofA549 cell.This experiment is to reveal the effect ofLingqi Capsule on expression VEGF, MMP-2 and MMP-9 in A549 cell and mechanism ofanti-tumor.Methods:Medicated serum was prepared with serum-pharmacology methods, the the effect ofmedicated serum on VEGFmRNA and protein expressions ofMMP-2 and MMP-9 was detected by RT-PCR technology and immunohistochemistry respectively.Results:It suggested that the VEGF mRNAcorrect value ofthe administration group was respectively(0.804?0.020),(0.836?0.022)and(0.914?0.009),the blank control group was(0.905? 0.033)and positive control group was(0.766?0.014).Difference between the administration group and the blank control group was significant(P

The content of geniposide in Compound Zhizi Granules was determined With TLC-scanner. The optimum experiment design obtained with orthogonal test could eliminate the disturbance of other components. The result was satisfactory.

Objective A solution of serial communication in Multi-Axis Controller which uses programmable multi-axis controller (PMAC) as down processor and PC as up processor is introduced. By the PComm32.dll provided with Delta Tau Data Systems Inc., the serial communication between PC and PMAC is realized based on .NET. Methods In order to realize the programming techniques of serial communication, a new method that managed codes invoked the unmanaged codes in Common Language Runtime environment by using Platform Invocation Services was adopted. The serial communication program was designed by using the program language C#. Besides the single axis locomotion,the debugging procession of the multi-axis joint locomotion was also recounted based on the five-DOF robot. Results The results indicated that the serial communication between PC and PMAC was completely realized. Conclusion The developed serial communication software module is of good correctness, stability and reliability, and also shows that the software is convenient and easy to use, which can accord with system requirements.

Angiotensin converting enzyme (ACE) gene is one of the major candidate genes for genetic susceptibility to kidney disease,but there is still a controversy on the correlation between ACE gene polymorphism and kidney disease.In this paper,the research on the correlation between ACE gene polymorphism and kidney disease in children is reviewed.

Homocysteine(Hcy) is an intermediate product of methionine metabolism.It is considered that Hcy is an independent etiological factor of cardiovascular disease,and blood Hcy level is closely related to many diseases.Patients with kidney disease may have different levels of homocysteine.The study has found that Hcy may not only be related to kidney damage,but also make the risk of cardiovascular disease in patients with kidney disease increased.The relationship between Hcy and kidney disease is briefly introduced in this article in order to provide a new basis for prevention,diagnosis and treatment of kidney disease and complications.

There are 5 literatures related to the clinical applications of cancer vaccination in hematologieal malignancies in the 18th annual meeting of the European Hematology Association (EHA).This article provides an overview of these literatures that helps to understand how cancer vaccination can be explored for future clinical interventions.
