Methods: The shape and formation of superior lumbar triangle were observed from the external surface of posterior abdominal wall. The grouping patterns and courses of subcostal nerve, iliohypogastric nerve and ilioinguinal nerve passing the front of superior lumbar triangle were also observed.

从腹后壁外面观察腰上三角的形态及构成，由其内面观察经过该三角前方的肋下神经、髂腹下神经和髂腹股沟神经的组合形式及走行，并分别测量其与第12肋下缘的距离。

The two other main branches of the dorsal ramus are the intermediate branch, which sends fibers into the longissimus muscle,and the lateral branch, which innervates the iliocostalis muscle, the thoracolumbar fascia, the skin of the lower back and buttock, and the sacroiliac joint.29,136,137 At the superomedial border of the trans-verse processes where the lumbar medial branches are most amenable to blockade, these nerves are in such close proximity that anesthetizing any one of them will almost invariably lead to blockade of the others branches of the primary dorsal rami.

背侧支另外的两个分支是支配最长肌的中间支及支配髂肋肌、胸腰筋膜和下腰部皮肤，臀部及骶髂关节的外侧支。在横突上内侧缘，内侧支容易被阻滞，在此处的神经彼此距离很近，阻滞一支即可将其他背侧支一齐阻滞。

Objective To introduce the clinical olwer, ation of cutaneous distribution of the ilioinguinal nerve on the labia major and diagnosis and local injection treatment of its neuralgia.

目的 介绍髂腹股沟神经在大阴唇皮肤分布区的临诊观察及神经痛的诊断与局部注射的治疗方法方法选择门诊确诊为髂腹股沟神经痛或股后皮神经痛累及其会阴支的女性患者共28人计31侧，细查计刺痛觉的变化以确定诊断及两神经分布区的范围采取强的松龙25mg+2％利多卡因或1％普鲁卡因5～10ml注射最大可能致病部位结果注射后数分钟检查麻醉范围。

BACKGROUND: Iliosacral screw fixing the sacroiliac joint after reduction can provide the stability of the pelvis.

背景：骶髂螺钉直接固定复位后的骶髂关节，可提供足够的骨盆稳定性，其生物力学稳定性优于其他常用的内固定。

Study of applied anatomy of the infrarenal abdominal aorta will supplement the domestic data of abdominal aortic anatomy.

根据影像学资料得到的数据分析得出：肾动脉下腹主动脉的前后径为15.53±2.39mm，左右径为15.03±2.09mm；左髂总动脉终端的直径为8.47±1.05mm，右髂总动脉终端的直径为8.59±1.17 mm。

Methods To dissect fifty health adult corpses(33 male ,17 female)and measure the corpses height, the length of the infrarenal abdominal aorta,the length of left and right common iliac arteries. The aortic diameter of the position on the infrarenal abdominal aorta is measured and the height is compared between the lelt and right renal artery at the same time.

方法采用50具健康成人尸体标本(男性33例，女性17例)，测量身高，解剖左右肾动脉、肾动脉下腹主动脉、左右髂总动脉及股动脉分叉部，分别测量肾动脉下腹主动脉至左右股动脉分叉部的长度，测量左右髂总动脉长度，测量肾动脉平面腹主动脉的直径，比较左右肾动脉位置的高低。

Objective: To analyze the clinical characteristics of diagnosis and therapy of pyogenic sacroiliitis. Methods: 4 cases were analyzed retrospectively and reported; and related literatures were reviewed.

目的：回顾分析4例误诊为强直性脊柱炎的化脓性骶髂关节炎的病例，探讨化脓性骶髂关节炎的临床表现、诊断、治疗方法。

In this experiment, we were successful to establish the finite element model of pelvis after subtotal sacrectomy. The calculated result was similar with the reference. The model could be used to evaluate different ways to reconstruct the sacroiliac joint.

成功建立了保留骶髂关节活动的骶骨次全切除术后骨盆的有限元模型，计算结果与文献中报道的结果较好地吻合，可认为有效，能够用于各种骶髂关节重建方式的有限元评价。

The distances between inferior margin of 12th rib and the 3 above-mentioned nerves were all measured. Results: The superior lumbar triangle was quadrilateral (55%), triangular (35%) or irregular (5%). If the 12th rib was too short, the upper border of the triangle would be the 11th rib (5%). Four grouping patterns of the 3 nerves were found in front of the triangle, and the average distance between inferior margin of 12th rib and the 3 nerves was (16.92±6.32)mm,(59.49±14.97)mm and (112.49±17.15)mm, respectively.

结果：腰上三角的形态可为四边形(55%)、三角形(35%)和不规则形(10%)，该三角的上界可完全由第11肋(5%)构成；肋下神经、髂腹下神经和髂腹股沟神在腰上三角前方有4种不同的组合形式，三神经与第12肋下缘的平均距离分别为(16.92±6.32)mm、(59.49±14.97)mm、(112.49±17.15)mm。

ObjectiveTo find out the reason of sacro-iliac articulation malposition misdiagnosed as single prolapse of lumbar intervertebral disc, define the essential point of diagnosing sacro-iliac articulation malposition, and choose the best treatment.

目的明确骶髂关节错位误诊单纯腰椎间盘突出症的原因，确认骶髂关节错位的诊断要点，以便选择最佳的治疗方法。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.
