梅罗综合征和螺旋体感染的关系

用Ｗａｒｔｈｉｎ－Ｓｔａｒｒｙ螺旋体特殊染色法及透射电镜观察，分别在１９例肉芽肿性唇炎和５例梅罗综合征（ＭＲＳ）病人的病变组织内发现有螺旋体存在，并对其在光，电镜下的形态和在病变组织内的分布部位进行了描述。经用大刘量青霉素治疗１１例病人，１０例有效。本结果为ＭＲＳ的发可能和螺旋体感染有关的推测提供了依据。     

二尖瓣狭窄的外科治疗(附85例报告)

本文报告1972年8月至1987年8月我院85例风湿性二尖瓣(犭央)窄或伴有轻度关闭不全病人的外科手术疗效。80例行闭式扩张术,5例行直视扩张术。贵州地区病人体型较小,瓣膜损害较重。瓣口扩张2.8～3.5cm,较一般要求偏小。手术后近期疗效较好。     

RETINOBLASTOMALACTIC DEHYDROGENASE OF AQUEOUS HUMOUR AND ITS ISOENZYMES

Lactic dehydrogenase (LDH) activity in aqueoushumour and serum was measured of 24 patients withretinoblastoma, senile cataract, glaucoma, and cho-roid melanoma in addition to LDH isoenzyme fractions. The results were compared with those of the20 normal children. The ratio of aqueous humourLDH to serum LDH was 4.32+2.80, and that ofisoenzymes LDH4 to LDHl was greater than l. Theresults of our study suggested that the total LDHactivity and isoenzyme fractions in the aqueoushumour is of value in the diagnosis of retinobla&toma.     

缺血－再灌注兔心肌肌浆网自由基的测定

应用电子自旋共振波谱仪（ＥＳＲ）直接检测了缺血－再灌注兔心肌肌浆网自由基的变化，以探讨肌质网系统与氧自由基的关系。实验中将２０只兔随机分为再灌注对照组、超氧化物歧化酶（ＳＯＤ）组、ＡＴＰ－氯化镁组和人参皂甙Ｒｅ组。实验结果，ｇ值２．００４６处为半醌自由基波谱，其相对浓度各组依次为７８．９４±２．１２６，１４．４６±２．８６，２０．６５±７．６５，１４．６６±３．６７（ｘ±ＳＤ），对照组与用药组均有显著性差异（Ｐ＜０．０５），表明缺血－再灌注兔心肌肌浆网产生大量的自由基，用ＥＳＲ可以直接检测到半醌自由基，外源性高能磷酸盐制剂ＡＴＰ－氯化镁及人参皂甙Ｒｅ与超氧化物歧化酶一样，发挥清除兔心肌肌浆网自由基的作用。     

活动翼矫治器的研制与初步应用

目的评价活动翼矫治器的设计原理与矫治效能。方法应用活动翼矫治器对588例错畸形病例进行矫治。对2001年～2004年的389例进行研究,分析其疗效、疗程、复诊次数、弓丝使用等情况。结果病例完成时间为4～15个月,平均为8.13个月。复诊次数4～13次,平均7.55次。平均每例上颌使用弓丝1.95根、下颌1.98根。仅11例病例使用口外支抗。结论活动翼矫治器是一种新研发的高效能矫治器,能够明显缩短疗程、减少复诊次数、减少弓丝用量     

甘温除热法治疗多脏器功能不全综合征高热的临床体会

多脏器功能不全综合征（MODS）是重症监护病房（ICU／EICU）病房常见的危重症，目前中医对于MODS高热的治疗多以清热解毒、清热凉血、清热通腑等去实热的治法为主，而以甘温除热为主的反治法退热的论述并不多见。作者通过具体病案说明甘温除热法对于MODS高热治疗的理论基础和应用体会，突出阐明代表方剂补中益气汤甘温除热的机理并不在于针对某种或某几种难治细菌有特定的抗菌作用，而是针对多数MODS后期高热产生的病因病机是因虚致热这一特点，治病求本。     

间隙连接蛋白家族新成员Cx36

Cx36是哺乳动物间隙连接蛋白(connexin,Cx)家族γ亚类的第一个成员,它参与形成间隙连接,介导相邻细胞间的物质和信息的直接交换。间隙连接是神经系统构成电突触的结构基础,参与调控神经冲动信息的传递和复杂神经网络的整合,而Cx36是唯一一个在神经系统中优先表达的Cx,因此成为电生理研究领域的热点。就Cx36的发现过程、结构和定位进行了总结,并着重介绍它在神经系统中的功能和调节机制。     

术中使用缓释型5-FU对于进展期结肠癌的疗效研究

随着生活水平的提高,恶性肿瘤的发病率也逐年增高,最新资料统计表明,目前全球结肠直肠癌病人每年有100万之多[1]。在我国其发病率近年来也呈明显上升趋势,到目前为止,结肠直肠癌病人的术后5年生存率也一直徘徊在50%左右[2]。因而如何有效地进行结肠肿瘤治疗,无论是在手术还是在其他辅助治疗方面都值得我们深入地探讨和研究。     

Treatment of severe subglottic laryngotracheal stenosis using hyoid graft with sternohyoid muscle flap]

OBJECTIVE: To evaluate the possibility and reliability of the hyoid-sternohyoid graft transfer in the correction of server subglottic laryngotracheal stenosis, and delineate the operation skills and clinical results. METHODS: Seven patients with severe subglottic stenosis underwent laryngotracheal reconstruction using the hyoid grafts with sternohyoid muscle flaps (HG-SHMF). Five of these patients had traumatic subglottic stenosis, one with scar tissue of unknown etiology arising in the subglottic region, another with tracheal narrowing caused by inhalation of hydrochloric acid. RESULTS: All seven patients were successfully decannulated with moderate good voice. The average time from reconstruction to decannulation was 15.4 months. The stent was endoscopically removed with a range of 3 to 22 months; the mean time required for stenting was 9.6 months. Two patients who received additional salvage reconstruction procedures because of graft or stent displacement were extubated with improved voices and satisfactory airway. CONCLUSIONS: The HG-SHMF transfer was a single-stage reconstruction, relatively simple procedure that can restore an adequate airway and a good voice. Patients undergoing laryngotracheal reconstruction with HG-SHMF must have regular, long-term follow-up since graft displacement and recurrent granulation tissue or scar reformation can cause restenosis after an initially successful surgery. This procedure should be used in a large number of patients to further test its reliability.
