横断面

Objective To investigate the impact of delivery on the sexuality of primiparous women in China,and the association with delivery type.

目的 了解产后各种不同类型性生活质量问题的发生率，以及分娩方式与产后性生活质量的关系。方法采用横断面研究方法，对在重庆医科大学临床学院产科分娩活婴的 4 6 0例初产妇的产科住院记录和产后 6个月内的性生活资料进行分析。

This study was aimed to investigate the impact of childbirth on the sexual health of primiparous women in China, understand the incidence of women s sexual problems after childbirth, common types and identify factors associated with dyspareunia.

中文摘要：为了解分娩对我国初产妇性健康的影响、产后各种不同类型性问题的发生率以及与性交疼痛发生的相关因素，我们采用横断面研究方法，对2000年11月至2001年7月期间在重庆医科大学临床学院产科分娩活婴的所有初产妇（n=796）进行门诊调查。

Transverse section al anatomy and clinical significance of the pterygopalatine space

方法选用成年尸体头颈部20例制成连续横断面，观察翼腭间隙及其结构的解剖学关系，利用游标卡尺及求积仪分别测量其长径、宽径和面积。

The regurgitant volume was calculated by temporally integrating the instantaneous flow volume rate of each frame during systole.

建立了基于经食道旋转扫描二维和经胸实时三维超声多普勒血流图像获取方法和图像插值、配准算法获得体数据，经多维重建描述二尖瓣反流速度的空间分布，立体观察返流的时相、方向、反流束长度、面积、体积、空间传播和严重程度等；通过重建反流后的速度场，从血流动力学角度分析了二尖瓣反流的性质，计算偏心反流束的湍流强度，利用反流束角度和湍流强度对计算结果进行修正；基于实时三维彩色多普勒成像技术，利用控制体原理对二尖瓣反流束在反流瓣口横断面的速度分布进行空间与时间积分获得二尖瓣偏心性反流的每搏反流量。

The "daVinci representation"(right panel of Figure 6) is a comprehensive visual representation of the scoliotic spine that illustrates the orientation of the planes of maximum curvature of the 3 spine segments in the transverse view. The center of the circular plot is the point where the central hip vertical axis (CHVA, CHVA is a true vertical bisecting the bi-femoral head axis, often considered to represent the physiological center of balance of the spine-pelvic unit) intersects the transverse plane and every arrow radiating from the center represents a spine segment (PT, MT, and TL/L).

圆的圆心是位于髋中心的Z轴与横断面相交点(CHVA，CHVA是双侧股骨头连线重点的垂线，通常作为脊柱-骨盆单元生理平衡的中点)及每个箭头发自表示脊柱节段的中心。

Results:Fractures were demonstrated definitely with transaxial imaging,SSD and MPR in all patients.The length,shape,direction and displacement of fractures,the appearance,size and space location of detached bone fragments,and dislocation of joint were displayed stereoscopically by SSD.Joint disruption and detached bone fragments within joint could be best viewed by MPR.

结果：所有病例CT横断面、SSD和MPR像均明确地显示了骨折，SSD像立体地显示了骨折线的长短、形态、走向，碎骨片的形态、大小、空间位置以及骨折的移位和关节对位状况，跨关节MPR像显示关节受累和关节腔内游离碎骨片更佳。

Fruit ovoid-oblong to subcylindrical, glabrous; mericarps subpentagonal in cross section; ribs 5, acute, narrowly winged; vittae small, numerous, obscure when mature.

果卵球形长圆形到次圆筒形，无毛；分果爿近五角形在横断面上；棱5，锐尖，狭翅；油管小，成熟时许多，阴暗。

Fruit ovoid or ellipsoid, slightly laterally compressed; mericarps subpentagonal in cross section; ribs 5, filiform, prominent, acute-ridged, almost narrowly winged; vittae 1 in each furrow, 2 on commissure.

果卵球形或椭圆体，稍侧面压扁；分果爿近五角形在横断面上；棱5，丝状，突出，锐尖使成脊状，几乎狭翅；油管每棱槽1，在合生面上2。

Seed subterete in cross section, face deeply sulcate.

种子在横断面近圆柱状，表面具深槽。

Plasma specific antibodies IgA, IgG, IgM to Cpn were measured by microimmunofluorescence test. A group of individuals with Cpn specific IgA (titler:32) suggested chronic Cpn infection were compared with a group of control subjects with IgA (titler:32). Blood specimens were drawn for determination of serum lipids and Cpn antibodies. And the serum lipids profile were compared in the two groups.

横断面研究方法；采用微量免疫荧光法检测血浆中肺炎衣原体特异性抗体，以肺炎衣原体IgA升高（滴度≥1：32）的125名健康体检者为研究组，以性别、年龄近似但IgA必抗体效价不升高（滴度：32）的64名同期体检者为对照组，比较2组血清总胆固醇、甘油三酯水平的差异。
