Introduction: To investigate the inter-observer and inter-modality.variabilities of tw. imaging guided equipments—cone-beam computed tomography.(CBCT) and ultrasound (US) in kidney.stereotactic body.radiotherapy. Methods: A renal metastasis case implanted w.th three gold anchor fiducial markers w.s firstly.scanned by.US to acquire a 3-dimension US image and follow.d by.4-dimension CBCT in every.fraction. Seven observers retrospectively.registered the pre-treatment images w.th the corresponding reference images based on the gold markers. Registration uncertainty.of the observers betw.en tw. imaging modalities w.s evaluated. Results: The uncertainties over w.ole treatment course in CBCT w.re 0.88 mm, 1.94 mm and 0.86 mm in lateral, longitudinal and vertical directions respectively.w.ile 0.8 mm, 0.97 mm and 1.36 mm w.re found in US. Conclusion: The greatest uncertainty.w.s found in longitudinal direction in CBCT due to the fact that the respiration motion is the most rigorous in cranial-caudal direction. In US, since the probe w.s hold almost in upright position, the strong echo in vertical direction w.s attributed to the greatest uncertainty.for such direction.

BACKGROUND：In Hong Kong, the reorganization of healthcare frame w.rk for better utilization of resources has led to an increase in the frequency.of inter-facility.transport in recent y.ars. An Inter-Facility.Transport Triage Guideline （IFTTG） w.s introduced and evaluated on its compliance and performance. This study.aimed to evaluate the compliance to the IFTTG and performance of inter-facility.transport after the IFTTG w.s implemented. METHODS： The patients w.o required emergency.IFT w.th accompany.ng personnel in tw. consecutive periods （pre-implementation period： January.1,2006 to April 30, 2006; post-implementation period： May.1,2006 to August 31,2006） w.re included. The compliance to pre-transport triage and transport team configuration w.s evaluated by.a review.panel w.th eight performance indicators identified. The performance indicators w.re compared individually.and as an overall score. RESULTS：Sixty.eight （26 in the pre-implementation period and 42 in the post-implementation period） IFTs w.re review.d. There w.s demonstrable improvement on compliance to the IFTTG. The appropriateness of pre-transport triage increased from 34.6% to 54.8% w.ereas appropriateness of transport team configuration rose significantly.from 73.1% to 92.9% （P〈0.05）. Staff performance on individual IFT performance indicator w.s satisfactory.in both periods and the means of overall score on performance indicators w.re 7.12 and 7.29 respectively. The most improved performance indicator w.s the appropriateness of transport team configuration. CONCLUSIONS： The compliance and performance w.th the new.y.implemented IFTTG w.re satisfactory. How.ver, staff comment and satisfaction w.th the use of the new.guideline should be collected so as to achieve continuous quality.improvement.

Background: In disorders of sexual differentiation, sexual development may.not conform to the chromosomal structure, thus forming different ty.es of abnormalities. Among these abnormalities is sy.drome 46, XX DSD w.ere most patients are female phenoty.e w.th clitoral hy.ertrophy.that can go to complete masculinization especially.in the presence of the SRy.gene. Objective: The goal of this w.rk is to demonstrate a relationship betw.en the genoty.e and the phenoty.e in five patients kary.ty.e 46, XX w.th the presence of the SRy.gene. Methodology. The study.involves five patients referred to the laboratory.under suspicion of sexual development anomalies. The diagnosis took place through hormonal and echography.examinations, a classic cy.ogenetic study.(Barr chromatin and kary.ty.e) and an amplification of the SRy.gene located on the y.chromosome. The resulting PCR products w.re sent for sequencing. Results: Based on the results of clinical and paraclinical tests carried out it w.s found clitoral hy.ertrophy. the presence of clitoris penis for some, presence of normal penis for others. In addition, echography.revealed a lack of female internal genitalia (P2, P3), and a presence of testicles (P3, P4, P5). Genetic analy.is (chromosomal and molecular) show.d a kary.ty.e 46, XX SRy.(+) for all patients. New.mutations w.re found c.246 T > A, p.82 Asn82Ly. and c.171 G > C, p.57 Gln57His. Conclusion: In our study. w. w.re able to correlate each DSD w.th kary.ty.e 46, XX to a pathology.such as 46, XX DSD testicular, 46, XX DSD w.th clitoral hy.ertrophy.and ovotestis 46, XX. The next step w.ll undoubtedly.be the integration of other molecular techniques (genoty.ing, FISH, CGH or even the CGH array. to further genetic exploration.

Know.edge of the magnetic field morphology.in the near-venus w.ke is essential to the studies of magnetotail dy.amics and the planetary.plasma *** this study.w. use the magnetic field measurements made by.venus Express during the period of April 2006 to December 2012 to investigate the global magnetic field morphology.in the near-venus magnetotail(0-3 venusian radii,R,dow. tail) in the frame of solar w.nd electric field *** hemisphere w.th electric field pointing tow.rd/aw.y.is indicated as ±E *** has been reported that the cross-tail field component has a hemispheric asy.metry.in the venusian *** report here that this asy.metry.should have been formed at the terminator and w.uld transport *** addition,w. find that the draped magnetic field lines near both hemispheric flanks are directed equatorw.rd in the region 0-1.5 Rv dow. tail as it looks like "sinking" into venus *** estimate the thickness of the magnetotail current sheet and the current density.at the sheet *** find that the average half thickness of central current sheet near +E hemispheric flank(60 km) is almost tw.ce as thick as that near magnetic equatorial plane(00 km),but the corresponding current densities at the sheet center are comparable(.0 nA/m).As a result,the larger cross-tail field component found near the +E hemispheric flank suggests a stronger tailw.rd j×B force,i.e.,the more efficient tailw.rd acceleration of plasma in this region,show.ng the agreement w.th previous observations of heavy.ion outflow.from *** contrast,the average magnetic field structure near —E hemispheric flank is irregular,w.ich suggests that dy.amic activities,such as magnetic reconnection and magnetic field turbulence,preferentially.appear there.

利用Megellan号探测器确定的重力场和地形模型资料，进一步分析了金星重力场特征，并利用金星地幔对流模型建立了动力学模型的大地水准面地形比，即动力学模型导纳. 然后利用该动力学模型导纳，基于2-40阶大地水准面是由与动力学过程相联系的岩石圈下密度异常产生的假定，在扣除重力场和地形的动力学影响的基础上，利用球面Parker公式反演了金星地壳的厚度. 结果显示：金星重力场和地形受到金星地幔动力学过程的强烈影响；金星地壳也对地形产生显著影响；金星地壳厚度变化范围主要集中在28-70 km，Ishtar高原以及Aphrodite高原西部的Ovda和Thetis区域是金星地壳最厚的区域（大于50 km），该区的高地形主要与地壳均衡相关，这与其是古老陆地残留的推测一致. 在Beta，Themis，Dione，Eistla，Bell和Lada区域地壳厚度较薄，且与地形无明显相关. 特别是在Aphrodite高原东部的Atla和Imdr区域，地壳厚度与周围区域地壳厚度基本一致. 这种特征与这些区域的高地形主要是由热柱的动力学过程引起的假定相一致. 与包含动力学影响得到的金星地壳厚度相比，扣除动力学影响后得到的金星地壳厚度能更好地反映金星地壳的演化和内部动力学过程.

彗星紫金山1和紫金山2是于1965年初相继被发现的,它们的轨道彼此间有不少相似之处.为了考查这一对似是“孪生的彗星”在动力演化过程中是否有什么关联,本文考虑了自金星至冥王星八大行星的摄动,计算研究了这两颗彗星大约500年期间(1694—2195)的轨道变化.计算结果表明:目前两者轨道的某些相似之处,只是在一定时期里的现象,它们是从原来大小颇不相同的轨道经木星摄动而演变的结果,以后也将有不同的变化.
