唇裂术止血减张固定器的研制和实验与临床研究

目的：为了减少唇裂修复术中出血，便于手术操作，缩短手术时间，相对地减少手术的危险性。方法：利用压迫止血及滑杆的原理，自行设计制作了唇裂术止血减张固定器，经过动物实验证实，在2h以内不会对组织有任何不可逆损伤，并成功地应用于唇裂修复术中。结果：临床应用68例，与传统止血方法比较，术中出血明显减少，便于手术操作，而且安全可靠，在2h以内不会对上唇组织有任何不可逆损伤，手术的危险性相对地减少。结论：应用唇裂术止血减张固定器进行唇裂修复术，术中出血明显减少．手术时间明显缩短，手术的危险性相对地减少，对减轻术后切口瘢痕有利，值得临床推广应用。

实验性小肠动脉出血的垂体后叶素灌注治疗

经动脉导管灌注垂体后叶素治疗１０条犬小肠出血的实验研究结果表明，垂体后叶素灌注治疗的效果与出血部位累及的血管大小及出血速率有关。还提示垂体后叶素对较大血管引起的出血灌注治疗无效，其引起血管的收缩作用主要在末梢小血管。     

An analysis of fluid loss during transcervical resection of submucous myomas

Objective: To determine the contribution of several variables to fluid loss during transcervical resection of submucous myomas.Design: An observational study using multiple linear regression analyses.Setting: A university-affiliated training hospital and a university department of clinical epidemiology and biostatistics.Patient(s): Patients with submucous myomas.Intervention(s): Transcervical resection of submucous myomas and monitoring of fluid loss.Main Outcome Measure(s): Patient age, uterine enlargement, treatment with GnRH analogues or 8-ornithine-vasopressin, type of anesthesia, number of myomas, intramural extension of the myoma (type of myoma), and operating time were tested as variables.Result(s): Only intramural extension of the myoma and operating time were obviously related to fluid loss. For the other variables, such a relation was weak at best. The relation between fluid loss and operating time was not modified by any of the other variables.Conclusion(s): Because fluid loss is an important limiting factor in the transcervical resection of submucous myomas, special attention should be paid to reduction of the operating time and preoperative assessment of the intramural extension of the myoma to guide appropriate patient selection.     

26例前置胎盘分娩方式临床分析

[目的 ]探讨前置胎盘分娩方式的选择及分娩过程中减少出血的方法。 [方法 ]对 2 6例前置胎盘病例的发病率、诊断方法、胎盘分型、分娩方式、出血情况及剖宫产术子宫切口方式与出血的关系几个方面进行回顾性分析。[结果 ]2 6例中手术率为 96 .1 5 % ,阴道分娩率为 3.85 % ,1例阴道分娩出血量为 6 0 0mL ,剖宫产术平均出血量为 6 74 .5 5mL ;剖宫产术中切口方式选择推开胎盘与避开胎盘出血量比较 ,差异无显著性 (P >0 .0 5 ) ,切开胎盘与推开胎盘出血量比较及切开胎盘与避开胎盘的出血量比较 ,差异均有显著性 (P均 <0 .0 1 )。[结论 ]剖宫产术可成为前置胎盘终止妊娠的主要方法 ,同时原则上应避开胎盘选择切口     

早期鼻饲生大黄粉防治重型颅脑损伤后上消化道出血的临床研究

目的研究重型颅脑损伤后早期鼻饲生大黄粉对防治上消化道出血的作用.方法选择GCS3～8分重型颅脑损伤患者90例,随机选45例(实验组)伤后早期(24～48h)鼻饲生大黄粉,另45例(对照组)未予生大黄粉治疗.所有患者其他治疗措施均基本相同.结果39例患者出现上消化道出血.其中实验组14例,有13例上消化道出血治愈,治愈时间(7.6±2.5)d;对照组25例,有16例上消化道出血治愈,治愈时间(13.4±3.3)d.实验组上消化道出血率和上消化道出血治愈平均时间均显著低于对照组(P＜0.05),而上消化道出血治愈率显著高于对照组(P＜0.05).结论早期鼻饲生大黄粉能有效防治重型颅脑损伤后并发上消化道出血,值得临床推广应用.     

新式非脱垂子宫阴式全子宫切除术45例报告

目的探讨非脱垂子宫经阴道改良切除的可行性及方法。方法将103例子宫肌瘤、子宫腺肌瘤、功能性子宫出血等需行全子宫切除术的患者随机分为两组，常规经腹式全子宫切除术(腹式组)58例，经阴道全子宫切除术(阴式组)45例，比较两种手术方法的优劣。结果阴式组较腹式组手术时间短，术中出血少，术后痛苦少；48h内肛门排气阴式组40例(88．9％)，腹式组31例(53．4％)；平均住院天数阴式组5．1d，腹式组7．1d。结论新式非脱垂子宫的阴式全子宫切除术相对于经腹式全子宫切除术有一定的优势，但要严格选择其手术适应证。     

Primary aortoduodenal fistula caused by duodenal tuberculosis without an abdominal aortic aneurysm: Report of a case

A 66-year-old man died of massive gastrointestinal hemorrhage caused by a fistula between the third portion of the duodenum and the abdominal aorta. An autopsy revealed that duodenal tuberculosis had resulted in the development of a fistula into the aorta with no pathological changes, and no active pulmonary tuberculosis was found. Duodenal tuberculosis and primary aortoduodenal fistula (ADF) without an aneurysm are both extremely rare. Thus, we report herein a unique case of primary aortoduodenal fistula without an abdominal aortic aneurysm, but associated with duodenal tuberculosis, and review the current literature.     

Atypical Allergic Colitis in Preterm Infants

ABSTRACT. Two atypical cases of colitis due to cow's milk protein intolerance (CMPI) are reported, affecting preterm infants. One developed a toxic dilatation of the colon and responded well to a casein hydrolysate based feed. The second presented insidiously and failed to tolerate a casein hydrolysate, but responded well to a chicken-based modular feed.
