后前位的

Diagnosis, degree of preoperative lordosis in the neutral position, and degree of preoperative sagittal alignment in flexion and extension were studied as risk factors for postoperative kyphosis.

诊断，术前中立位前凸角度和屈曲、伸展位矢状位序列成角被研究作为术后后凸畸形的危险因素。

在三类限定词中，中位限定词是最关键的。所谓前位限定词是指那些可以位于中位限定词之前的限定词，所谓后位限定词是指那些可以位于中位限定词之后的限定词。例如： all the four teachers 所有这四位教师前中后上述限定词的位置是固定的，不能掉换，就是说它们必须按"前位—中位—后位"的顺序排列。以此类推，如果出现两个限定词，则只能按前位—中位，前位—后位或中位—后位的顺序排列。

The results indicate that the fixation methods for supracondylar fractureshould b that:(1) The fixation with the flexion angle of 9O°in the pronator position is adopted if the medial side presents displacement and the lateral periosteum is broken and the "hinge"of the medial periosteum remained unbroken.

表明肱骨髁上骨折的固定方法宜采用：①若内侧移位，外侧骨膜破裂，内侧骨膜"铰链"完整，则采用屈曲90°旋前位固定；②若外侧移位，内侧骨膜破裂，外侧骨膜"铰链"完整，则采用屈90°旋后位固定；③若内外侧骨膜完全破裂，不论是内侧移位，还是外侧移位，宜采用旋后位固定。

This article studied differences in postpartum fatigue and birth outcomes between women who pushed immediately and those who delayed pushing during the second stage of labor. Data were collected from primiparous women in their 38th to 42nd gestational week who did not receive epidural analgesia during labor and were free of complications during pregnancy. Using a quasi-experimental design, 72 participants selected by convenient sampling were assigned based on individual participant's preference to either an experimental or control group. For the experimental group, pushing was delayed until the point after full cervical dilation at which the mother felt a strong physical pushing reflex, the fetal head had both descended to at least the +1 level in the pelvis and turned to the occiput anterior position, and uterine contractions were at least 30 mmHg. For the control group, the physician instructed mothers to begin pushing after full cervical dilation at the point when the fetal head was in the occiput anterior position and uterine contractions were at least 30 mmHg.

本研究目的在探讨初产妇女第二产程立即用力与延迟用力对产后疲惫及生产结果的影响，收案对象为怀孕38-42周初产妇女、待产期间未施打硬脊膜外麻醉，且怀孕期间无任何合并症，於待产期间向其解释研究目的及收案方法后予以收案，采类实验设计法，以方便取样并依个案之意愿分派於实验组及控制组，实验组於子宫颈完全扩张后等到强烈想用力的感觉、胎头位到达坐骨棘连线下1公分以下、胎头位置转到枕前位、子宫收缩规律强度至少30mmHg才教导向下用力；控制组於子宫颈完全扩张后即教导向下用力，共收案72位。

Among the 45 neurons generating phasic firing, 8 (17.78﹪) neurons could still be induced phasic firing after treatment with 1×10-2 μg/mL SVHRP and 37 (82.22﹪) neurons had no responses to the stimulation. The AP firing of neurons was dramatically different after treatment with SVHRP (P＜0.01, n=45). Among the 7 repetitive firing neurons, all of them could only generate 1 or 0 AP instead of repetitive firing when SVHRP was applied. The number of APs was 14.57±1.00 and 0.57±0.20 before and after SVHRP treatment (P＜0.01, n=7). The AP rheobase was (75.10±8.99) pA and (119.85± 12.73) pA before and after 1 × 10-4 μg/mL SVHRP application, respectively (P＜0.01,n=8). The AP threshold was increased from (-41.17±2.15) mV to (-32.40±1.48) mV after 1×10-4 μg/mL SVHRP treatment (P＜0.01,n=8). The peak amplitude of AP was (68.49±2.33) mV for the neurons before treatment with 1×10-4 μg/mL SVHRP and (54.71±0.81)mV after treatment (P＜0.01, n=8). These results showed that SVHRP could decrease the AP firing frequency, increase the AP rheobase and threshold, but decrease the AP peak amplitude of hippocampal neurons.

在产生位相放电的45个细胞中，有8个细胞在SVHRP处理后仍可以诱发出位相放电(占17.78﹪)；37个细胞在SVHRP处理后无法诱导出位相放电(占82.22﹪)，SVHRP处理后动作电位的产生与处理前相比，有显著差异(P＜0.01，n=45)；在产生重复放电的7个细胞中，在1×10-2μg/mL SVHRP作用后均不能再次诱发出重复放电，而是产生一个动作电位或不再产生动作电位，药物处理前产生的动作电位个数为14.57±1.00，SVHRP处理后产生动作电位的个数为0.57±0.20，二者之间有显著性差异(P＜0.01，n=7)。1×10-4 μg/mLSVHRP处理后，诱发动作电位产生的基强度由(75.10±8.99)pA增加到(119.85±12.73)pA(P＜0.01，n=8)；阈电位由(-41.17±2.15)mV升至(-32.40±1.48)mV(P＜0.01，n=8)；动作电位峰值由(68.49±2.33)mV下降至(54.71±0.81)mV(P＜0.01，n=8)。

Compared with standard images,bony images showed bony thorax more clearly,especially the ribs overlapped by heart and the subphrenic structures,and soft tissue images showed lung lesions more clearly.Conclusion DR energy subtraction chest films can show rib fracture and lung lesions clearly,and it is of diagnostic value for the patients of chest trauma and small lung lesions.
