高强度聚焦超声消融治疗子宫肌瘤时妊娠一例报告并文献复习

高强度聚焦超声(high-intensity focused ultrasound,HIFU)消融治疗子宫肌瘤作为一种新的非侵入性的治疗方式,已越来越广泛地用于子宫肌瘤的治疗。但是对于HIFU治疗时妊娠的处理及妊娠结局鲜有文献报道。本文报道1例HIFU消融治疗子宫肌瘤时妊娠的病例,结合文献复习,探讨子宫平滑肌瘤对妊娠的影响、子宫平滑肌瘤不同处理方式对妊娠的影响、HIFU消融治疗子宫肌瘤时机选择的问题、HIFU消融治疗子宫肌瘤若同时合并妊娠时胎儿去留的问题以及近期HIFU消融治疗子宫肌瘤后对流产手术操作的影响等,以期对HIFU治疗子宫肌瘤的适应证、选择合适的治疗时间及术后选择合适的妊娠时机展开讨论。

目的 探讨非脱垂子宫经阴道与经腹全切术的临床比较。方法 2000年5月～2001年1月对阴式子宫全切术 (TVH)28例及腹式子宫全切术 (TAH)35例分为两组进行手术 ,对临床指标进行观察比较。结果 28例TVH手术均成功。平均重量255g(120～510g)。与TAH手术比较 ,其术后病率、肛门排气时间及术后住院天数有显著性差异 ( p<0.001及 p<0.05) ,但其手术时间及术中出血量无显著性差异 ( p>0.05)。结论 随着微创手术的开展 ,利用阴道天然孔道 ,经阴道切除较大的子宫是有效和安全的 ,手术的成功与术者经验、技术及子宫活动度有关 ,有合适器械也是手术成功的因素。     

特殊部位异位妊娠的临床分析

目的探讨特殊部位异位妊娠的临床特点，误诊原因及治疗原则。方法对1996年1月至2003年12月诊治的256例特殊部位异位妊娠进行回顾性分析。结果特殊部位异位妊娠发生率占同期异位妊娠的3．36％，术前诊断率48．4％，所有的患者均行手术。视术中情况进行不同的处理，所得标本均经病理切片证实，全部患者愈后良好。结论特殊部位异位妊娠的临床表现不典型，容易漏诊误诊，一旦怀疑本病应尽早住院，及时明确诊断并手术，患者愈后良好。     

Pharmacological studies on siculine syrup. II: effects on smooth,skeletal and cardiovascular muscle preparations

Earlier pharmacological screening showed that siculine syrup (a traditional herbal remedy purported to be useful in the prevention and treatment of sickle cell pain – crises, due to sickle cell anaemia – SCA) had antisickling and analgesic activities as well as antimicrobial and diuretic effects. SCA is an important haemoglobinopathy in Africa and many other communities/countries worldwide, with relatively high morbidity and mortality. The present study was to determine the effects of the extract on various isolated muscle preparations – smooth, skeletal and cardiovascular. Siculine (4–20 µg/mL), like acetylcholine (40–400 µg/mL), contracted the isolated rat uterus concentration dependently. Similar effects were observed with the guinea‐pig ileum and rabbit jejunum (2–20 µg/mL). In contrast to these effects, the direct (muscle) and indirect (nerve) stimulations of rat phrenic nerve–diaphragm were relaxed by siculine (4 and 8 µg/mL) and d ‐tubocurarine (0.8 µg/mL). Siculine also concentration‐dependently decreased both the rate and force of contraction of guinea‐pig atria and rabbit heart and also resulted in a fall in cat blood pressure in a manner similar to those of acetylcholine. The possible therapeutic and/or toxicological consequences of these effects including the hypotensive activity is noteworthy since siculine syrup is used by the local population for the prevention and treatment of sickle cell pain crises.

妇女妊娠期及分娩前后子宫肌层的超微结构研究

扫描电镜（ＳＥＭ）和透射电镜（ＴＥＭ）观察证明，妇女非妊娠期子宫肌层内存在有胶原纤维网（ＣＦＮ）。妊娠中期和晚期及分后ＣＦＮ出现以时相性崩解和重建为主要特征的改建过程以适应子宫生理性能的巨大变化和功能需要。平滑肌细胞，成纤维细胞，肌纤维母细胞，巨噬细胞，中性白细胞及肥大细胞参与改建过程。它们既参与ＣＦＮ的溶解和吸收，又参与其重新形成，显示双重形态和功能。还对ＣＦＮ改建的机理，参与细胞间的相互作用，     

分娩期子宫破裂64例分析

目的 分析分娩期子宫破裂的发病原因及预防措施。方法 回顾分析1985年8月至2001年12月，16a间64例分娩期子宫破裂的临床资料。结果 子宫收缩剂使用不当3l例，占48．4％；胎先露下降受阻13例，占20．3％；子宫疤痕16例，占25％；阴道助产4例，占6．3％。初产妇10例(10．9％)；经产妇54例(89．1％)。结论 降低分娩期子宫破裂发生率关键在于加强计划生育工作及围生期保健，严格掌握子宫收缩剂的适应证及剂量；严格首次剖宫产指征；严密观察产程，及时处理异常分娩。

Inhibitory effects of chlorpheniramine and astemizolum on contraction of isolated rat and rabbit uteri induced by oxytocin and PGF2α

Summary The contraction of isolated rat and rabbit uteri induced by oxytocin and PGF_2α was markedly inhibited by chlorpheniramine (Chl) and astemizolum (Ast), both of which also decreased the resting tension of uteri, and their spontaneous contraction. The inhibitory effects of both drugs were dose-dependent. At high concentrations, Chl 7.4× 10^-4 mol/L and Ast 10^-4 mol/L could counteract the contraction of the uteri induced by Oxy and PGF_2α, and their spontaneous contraction as well. They decreased the resting tension to the lower level. The mechanism of their non-special relaxed action on uteri could not be completely explained only by their H₁-receptor blocking action. Whether they act by blocking calcium channel or by inhibiting calmodulin (CaM) remains to be further explored.
