瘢痕疙瘩的治疗进展

瘢痕疙瘩确切的发病机制尚不清楚，迄今仍没有能达到完全满意的治疗方法，目前提倡根据临床表现施以综合治疗以提高疗效，文章对多年来国内外瘢痕疙瘩治疗方法予以分类综述，为临床提供参考。     

3种常用化疗药对正常大鼠血清胃泌素及D-木糖醇浓度的影响

目的：观察3种常用化疗药对正常大鼠血清胃泌素及D-木糖醇浓度的影响。方法：将动物随机分为4组，即对照组、ETX组、5-Fu组和THP组，检测胃泌素及D-木糖醇浓度等指标。结果：3组化疗组上述指标与对照组比较，差异有统计学意义（P〈0．05，P〈0．01）。结论：正常大鼠用ETX、5-Fu和THP，血清胃泌素及D-木糖醇浓度明显减低，从临床表现、胃肠功能方面提示3种常用化疗药可导致正常大鼠脾虚证的发生。     

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.     

地震伤患者医院感染目标性监测

对某院收治的50名地震伤员进行医院感染目标性监测，有效地预防与控制医院感染的发生。通过分类安置伤员，专人目标监测，严格执行消毒隔离制度及手卫生、标准预防措施等，将医院感染发生率降至最低：仅1例重症挤压伤者发生医院感染，医院感染率为2．00％。     

噻吗洛尔与普萘洛尔治疗高血压病与心绞痛的疗效比较

劳累性心绞痛38例采用噻吗洛尔2.5-5mg, tid,共4wk;另12例采用普萘洛尔10-20mg, tid,共4wk。结果:前者显效率为79％,显著高于后者42％(P<0.05)。高血压病(Ⅰ,Ⅱ期)37例采用噻吗洛尔治疗,方法同上;另13例采用普萘洛尔20-40mg, tid,疗程亦4wk。结果:2组均有显著降压疗效(P<0.01),噻吗洛尔治疗后1h即获显效,普萘洛尔须24h才获显效。噻吗洛尔7％(5/75)、普萘洛尔4％(1/25)治疗后发生窦性心动过缓,前者被迫停药,后者未停药。     

小脑梗塞的CT和MRI诊断价值

目的 分析小脑梗塞CT和MRI表现,探讨CT和MRI对小脑梗塞的诊断价值。方法对18例小脑梗塞的CT和MRI图像进行回顾分析。结果CT和MRI不同程度显示了小脑梗塞的影像学改变,各有其特点,且与病程长短和病灶大小有关。结论MRI的影像学价值较CT更胜一筹。
