颞骨骨折性面瘫的临床和实验观察

为探讨影响颞骨骨折性面瘫预后的主要因素和面神经减压术的意义，总结分析了６４例面瘫预后的主要相关因素。制作面瘫实验西式，测定面神经骨管开放组和非开放线面神经膨胀率，并行电镜观察。结果表明，影响预后的主要因素是否行面神经减主及手术时机。骨管开放组面神经膨胀率显著大于非开放组，非开放组纤维损伤谋生时机提示早期行面神经减压术有 利于面神经功能恢复。     

Expression of Clara cell 10-kDa protein (CC10) in congenital diaphragmatic hernia

Clara cell 10 kDa protein (CC10) has been thought to be fairly specific to Clara cells and a major secretory protein that is both synthesized and released from Clara cells. In the present study, morphometric analyses of the immunohistochemical expression of CC10 were carried out on the bronchioles of human neonates with congenital diaphragmatic hernia (CDH) and then compared with morphometric analyses from a gestationally and postnatally age-matched control group in order to clarify the immaturity of Clara cells in CDH lungs. No difference was found in CC10 expression between the affected side and the unaffected side of the lungs in the CDH group. However, compared with the lungs of the control group, the CDH group showed a significant decrease in CC10 expression, namely, the ratio of CC10-positive cells per bronchiole, per unit perimeter of bronchiole, and per unit bronchiolar surface area. These results suggest that in the lungs of CDH cases, a possible delay in either functional maturation or the development of CC10 synthesis by the bronchioles may exist, and this retardation of functional maturation of the airway is also considered to play a role in the postnatal respiratory insufficiency observed in CDH patients.

神经肌电检测对单侧喉返神经损伤预后的评价

目的 探讨喉神经肌电位综合指标对声带麻痹预后的估价作用。方法 检测91例甲状腺手术单侧声带麻痹患者的喉神经电图及肌电位,按病程分成4组;分析各组恢复与未恢复声带运动的患者喉神经肌电位特征,以“95％可信区间”计算神经肌电位预后评估标准。结果 病程2个月内组最大诱发电位幅度明显低于2个月以上的其他各组,差异具有显著性意义(P<0.05),而2-4个月与4-6个月组的组间差异无显著性(P>0.05),故将病程2-6个月计为一组。2个月内组自然恢复与未恢复患者分别为2、11例,以引出诱发电位且无错向再生电位作为预后良好判断指标,准确率为92％(12/13)。2-6个月组恢复与未恢复患者各为11、48例,恢复者最大诱发电位幅度明显大于未恢复者,差异有显著性意义(P<0.01)。以引出诱发电位且电位幅度大于26.4％作为预后良好的判断标准,准确率90％(53/59);结合无错向再生电位综合判断预后,准确率为93％(55/59)。6个月以上组19例无论神经肌电位检查结果如何,声带运动均无恢复。结论 将神经肌电位进行综合分析,分别判断不同病程的声带麻痹的预后,可提高预后判断的准确率。     

甲状腺手术喉返神经损伤规律及治疗的探讨

目的 探讨甲状腺手术喉返神经损伤的规律及中早期神经减压的疗效。方法 甲状腺手术喉返神经损伤单侧声带麻痹87例,其中行喉返神经探查65例,非手术治疗22例。探查术中观察喉返神经损伤部位、类型、程度及神经肌肉形态;对缝扎、粘连伤行神经减压治疗14例。治疗前后以喉镜、嗓音声学参数、肌电图检查等评价治疗效果。结果 探查发现喉返神经被缝线结扎、瘢痕粘连压迫、断离分别占43％(28/65)、9％(6/65)、48％(31/65)。损伤部位以近环甲关节处多见,占75％(49/65);甲状腺中下部占25％(16/65)。病程半年以内者喉内肌及损伤处远端神经干萎缩并不严重,病程越长萎缩变性越明显。神经切断伤上述改变较缝扎伤及压迫伤更为明显;但病程18个月喉内肌仍可见肌纤维组织结构。病程3个月内神经减压10例中9例声带恢复了不同程度的内收及外展功能;病程3个月以内1例、3-5个月4例神经减压术后声带未恢复运动,但均恢复了正常的肌张力、肌体积,声带振动及黏膜波对称,嗓音亦恢复正常。非手术治疗组声嘶有改善,但嗓音未恢复正常,声带亦未恢复运动。结论 通过喉返神经探查初步揭示甲状腺手术喉返神经损伤的规律,中早期喉返神经减压术能恢复声带生理性运动功能。     

The combined endoscopic CO2 laser posterior cordectomy and total arytenoidectomy for treatment of bilateral vocal cord paralysis

The combined endoscopic CO₂ laser posterior cordectomy and total arytenoidectomy for treatment of bilateral vocal cord paralysis Upper airway obstruction, because of bilateral vocal cord paralysis, presents a serious challenge to the Otolaryngologist. Various surgical techniques have been advocated for the management of patients with vocal cord paralysis. Among these techniques, the individual use of laser CO₂ arytenoidectomy and posterior cordotomy has gained wide acceptance. In this report, we describe our experience in the management of bilateral vocal cord paralysis by combining posterior partial cordotomy as described by Dennis and Kashima, with total arytenoidectomy as described by Ossoff et al. We report the long‐term results in the management of 18 patients treated in our department during the last 8 years.     

术中面神经监测的动物实验与临床研究

目的：探讨术中面神经监测的参数与面神经减压术后面瘫的预后之间的关系。方法：对15只健康新西兰家兔30侧面神经及21例周围性面瘫患者进行术中面神经监测，术后随访6个月以上，使用χ^2检验评估术中监测的情况与减压术后面瘫的预后之间的关系。结果：15只家兔30侧面神经监测中不同个体的面神经阈值几乎均为0．05mA，在面神经的水平段、垂直段、颞骨外段其阈值也几乎均为0．05mA。21例面瘫患者，术中肌电图(EMG)引出者14例，其中13例减压术后面瘫的预后好，1例测舌差；EMG未引出者7例，其中1例减压术后面瘫的预后好，6例预后差。结论：术中面肌EMG的阈值能够较客观、稳定地评估面神经的功能。术中面肌EMG能否引出可以辅助预测面神经减压术后面瘫的预后情况，EMG能引出者预后好，反之则差。     

创伤性膈疝的X线与CT诊断分析

目的分析X线与CT在创伤性膈疝中的诊断价值及影像特点。方法对经X线、CT检查的35例创伤性膈疝患者(经手术证实)进行回顾性分析。结果①创伤性膈疝多发生于左侧膈肌,该组病例中X线与CT对该病的诊断符合率分别为68.6%和100%。②CT不仅可以明确诊断膈疝,还可判断膈破裂口的位置、大小、疝入物内容。③判断多脏器复合受损情况:CT在诊断肺挫裂伤方面与X线无显著性差异(P>0.05);CT在诊断液气胸、腹腔积液方面明显优于X线(分别为P<0.01,P<0.05);X线在诊断肋骨骨折方面明显优于CT(P<0.01);X线对肝、脾、脑、肾等实质性脏器的损伤方面无诊断价值。结论X线、CT在诊断创伤性膈疝中有着极其重要的作用,且CT是一种更敏感的检查方法,对创伤性膈疝的早期诊断及治疗、挽救患者生命有重大的意义。     

Hyperglycemia, hyperlipemia, and periodic paralysis: a case report of new side effects of clozapine

1. 1. This case report of a Chinese male schizophrenic patient describes new side effects that have not been documented previously for patients treated with clozapine. At certain doses of clozapine, the patient showed direct adverse reactions, which include a combination of hyperglycemia, hyperlipemia, and periodic paralysis.

2. 2. In a four-year study of this patient who had no previous episodes of diabetes in his or his family history, the authors found that these symptoms disappeared upon withdrawal of clozapine and relapsed with re-treatment of the drug.

3. 3. This study indicates that hyperglycemia, hyperlipemia, and periodic paralysis may need to be monitored on patients treated with clozapine.
