Predictability of retroperitoneal lymph node metastasis by using clinicopathologic variables in surgically staged endometrial cancer

The purpose of this study was to predict lymphatic involvement in endometrial cancer using clinicopathologic variables of patients treated with surgical staging. Overall, 461 patients treated with an initial surgical staging procedure including complete pelvic-para-aortic lymphadenectomy were included. The mean number of resected lymph nodes was 27 (median 26; range 15-83), and 54 patients (12%) had lymphatic involvement. Of these patients, 32 had only pelvic, 15 had both pelvic and para-aortic, and 7 had isolated para-aortic metastases. In the multivariate analysis, deep myometrial invasion (P= 0.02), lymphvascular space invasion (P= 0.001), positive peritoneal cytology (P= 0.002), and cervical involvement (P= 0.003) predicted retroperitoneal lymph node metastasis (RLN) significantly. Two hundred seventy-four patients (59.4%) had at least one of these poor prognostic factors identified by multivariate analysis. In this patient population, 53 (19.3%) had lymphatic involvement compared to 1 patient in the group of 187 patients with low-risk criteria. Ninety-eight percent of patients with RLN were predicted by this model, and with the advent of accurate diagnostic techniques, 40% of patients could be saved from undergoing lymphadenectomy.     

头皮冠状切口的并发症及其防治

目的：对采用头皮冠状切口所引发的并发症进行分析，探讨防治策略。方法：对我科2003-01～2006—07应用头皮冠状切口行颅颌面骨折修复重建、颌面部肿瘤切除与缺损修复、先天性颅颌面畸形矫正的221例中发生并发症的40例进行分析总结。结果：18例出现头皮麻木及感觉异常，9例有较宽切口瘢痕，6例出现脱发，4例发生颞窝凹陷，2例发生头皮下血肿，2例出现单侧面神经颞支损伤，1例发生鼻眶区肥厚。结论：头皮冠状切口具有切口隐蔽、面部疤痕不明显，显露充分的优点，但对其并发症也不容忽视。应根据具体情况选择合适的切口类型，术中精细的解剖、神经血管的良好保护以及正确的缝合方法可减少并发症的发生。

带隐神经交腿随意皮瓣修复足底皮肤缺损

目的 报道用带隐神经的小腿内侧带蒂随意皮瓣修复对侧足底皮肤缺损的临床效果。方法 在健侧小腿内侧隐神经走行区设计皮瓣，将隐神经保留在皮瓣中央，根据患足创面大小切取皮瓣，带深筋膜，蒂保留在胫前侧，将皮瓣缝合于患足的创面，皮瓣中的隐神经与患足足底内侧皮神经吻合，双下肢固定3周后断蒂。1997～2001年，临床应用13例。结果 用该皮瓣修复13例足底皮肤缺损均获得成功，皮瓣外形良好，术后6～12个月恢复感觉，无再破溃发生。结论 带隐神经交腿随意皮瓣切取简单，厚薄适度，不损伤知名血管，术后带感觉神经可恢复皮瓣的感觉，有效防止皮瓣再破溃。是修复足底皮肤缺损的较好方法。     

Effects of capsaicin in temporomandibular joint arthritis in rats

Temporomandibular joint (TMJ) arthritis was induced in female Lewis rats by unilateral injection of a suspension of heat-killed Mycobacterium butyricum in paraffin oil into the TMJ. Control rats received paraffin oil by the same route. Arthritic and control rats were pretreated either with capsaicin or denervation of the mandibular branch of the trigeminal nerve. Tissues were collected for neuropeptide extraction and analysed by radioimmunoassay and reverse-phase high-performance liquid chromatography. In all groups, the levels of substance P- (SP), calcitonin gene-related peptide- (CGRP) and neuropeptide Y- (NPY) like immunoreactivity (LI) were higher in the trigeminal ganglia than in the TMJs. In control rats, capsaicin significantly lowered the levels of SP-LI in the trigeminal ganglia and TMJ, but not CGRP-LI and NPY-LI. In the arthritic rats, capsaicin pretreatment significantly lowered the SP-LI and CGRP-LI in the trigeminal ganglia and TMJ, but not the NPY-LI. In the trigeminal ganglia the unilateral denervation significantly lowered SP-LI in control rats, and in arthritic rats SP-LI and CGRP-LI. On the denervated side of the arthritic TMJ, NPY-LI, SP-LI and CGRP- LI were significantly lowered as compared to the arthritic control rats and to the contralateral side. In this rat model, pretreatment with capsaicin and surgical denervation decreased the neuropeptide content in the trigeminal ganglia and the TMJ. The results clearly demonstrate a close interaction between increased neuropeptide release from sensory and sympathetic neurones after induction of arthritis in the rat.     

儿童原发性腹膜后恶性肿瘤的诊断与治疗
