普外科住院患者营养状况评价

目的　调查本院 2 0 0 2～ 2 0 0 3年间普外科住院患者的营养状况。方法　采用多项营养评价指标测定 4 0 12例非急诊住院患者营养状况 ,分析年龄、疾病等因素与营养状况之间关系。结果　各项指标进行营养评价得出本院普外科非急诊患者营养不良的发生率分别是 :BMI 2 1 3% ,TSF5 0 6 % ,MAC 2 0 5 % ,AMC 2 1 2 % ,SGA 38 0 % ,MNA 2 0 8% ,ALB 2 4 2 % ,PA 35 4 % ,TLC 5 5 8%。 >6 0岁组老年患者、消化道疾病患者及恶性肿瘤患者营养不良发生率分别高于≤ 6 0岁患者、消化道外疾病患者及良性疾病患者 ,差异有显著性 (P <0 0 5 )。结论　本院普外科住院患者的营养不良发生率为 2 0 5 %～ 5 5 8% ,不同的营养评价指标得出的营养不良发生率不同。     

复杂LC术中胆管损伤的预防:附272例报告

随着腹腔镜胆囊切除术（LC）的广泛开展及技术水平的日益提高，LC已被认为是胆囊切除的金标准。手术适应证逐渐扩宽，这也对手术者提出了更高的要求。内江市第六人民医院在1997年3月至2006年3月9年间共行LC手术1378例，其中复杂LC 272例，结合临床经验及教训就有关问题进行分析讨论。[第一段]     

The laterally extended medial hemisoleus flap for reconstruction of a tibial wound in the distal third of the leg

A soleus flap as a local reconstructive option for soft-tissue coverage of a tibial wound in the distal third of the leg has never been well recognized. In a 2-year period, seven patients underwent reconstruction of a less extensive tibial wound (4 × 3 to 10 × 4 cm) in the distal third of the leg after orthopedic trauma with the laterally extended medial hemisoleus flap. The flap was elevated with emphasis on the preservation of the most distal perforators from the posterior tibial vessels to the flap as possible while allowing adequate rotation of the flap to cover the exposed tibia and/or hardware and on the possible preservation of foot planter flexion by reconstruction of the proximal Achilles’ tendon. In this series, there was no total or partial flap loss. All patients healed their tibial wounds primarily with reliable soft-tissue coverage, evidenced fracture healing, and good cosmetic outcome during follow-up. Thus, the laterally extended medial hemisoleus flap described by the author can be a reliable option for soft-tissue coverage of a less extensive tibial wound in the distal third of the leg. It offers a more cost-effective approach for managing this unique problem and can be performed by most reconstructive surgeons without microsurgical expertise.     

Vitapex糊剂用于患儿根尖诱导成形术的护理配合

根尖诱导成形术（apexficaotion，AP）是指牙根未完全形成之前，在消除感染或尖周炎症的基础上，用药物诱导根尖部牙髓和俄根尖周组织，使牙根继续发育并使根尖形成，行永久性充填。2002年-2005年我科将Vitapex糊剂用于儿童患牙行根尖诱导成形术，效果较好：现将护理配合介绍如下。     

几种手性药物对映体的HPLC分离与生物样品分析

使用ＣＨＩＲＡＬ－ＡＧＰ柱，通过优化色谱条件，以ＨＰＬＣ法对３种手性药物ＳＦＺ－４７〔（±）－３Ｈ－１，２－二氢－２－（４－甲基苯胺基）－甲基－１－吡咯里嗪酮〕，ＫＭＢＺ－００９〔（±）－反式－４－苯基－５－（邻氯苄基）－吡咯烷酮－２〕和地丙苯酮〔（±）－２′－（２－羟基－３－（特戊胺基）丙氧基）－３－苯基苯丙基酮〕进行了对映体的直接分离，达到良好的分离效果．在此基础上测试了动物血浆样品中ＳＦＺ－４７的对映体，对其药物动力学的对映体选择性进行了初步研究．     

Localizing and photosensitizing mechanism by tetra(3-hydroxyphenyl)porphin in vivo on human malignant melanoma xenografts in athymic nude mice

Observations on time-dependent localization of tetra(3-hydroxyphenyl)porphin (3-THPP) in human malignant melanoma transplanted to athymic nude mice from 1 to 120 h after intraperitoneal (i.p.) 10 mg kg^–1 b.w. administration were made by means of fluorescence microscopy. Fluorescence was found on the membrane of the melanoma cells and in the cytoplasm with a peak fluorescence intensity at 24 h post-injection of 3-THPP. The growth of the tumour cells was obviously inhibited at an early stage after PCT. Morphological changes of the tumour at various intervals after treatment by PCT with 3-THPP were also observed. Diffuse degeneration of the tumour cells with swelling of mitochondria and endoplasmic reticulum, heterochromatin aggregation and margination, etc., and subsequently diffuse necrosis with little or no the background of tumorous vascular response were found at an early stage after PCT. On the other hand, it was also observed that the necrosis of the melanoma areas was caused as a consequence of tumorous vascular injury at a later stage after PCT. Thus, two tumoricidal processes caused by PCT with 3-THPP were seen: a direct phototoxic action on tumour cells at an early stage after PCT and an indirect effect secondary to tumorous vascular injury at a later period after PCT.
