机械球磨法制备吲哚美辛包合物及其溶解性研究

目的 研究机械球磨法制备的吲哚美辛(Indometacin,IMC)包合物对其溶解度及溶出度的影响。方法 采用机械球磨法制备IMC/羟丙基-β-环糊精(HP-β-CD)和IMC/阿拉伯半乳聚糖(AG)包合物体系。通过相溶解度实验、差示扫描量热法、X射线衍射法、红外光谱、扫描电子显微镜、体外溶出和稳定性实验等对制备的包合物进行考察。结果 相溶解度实验及表征实验表明IMC以无定型状态按照摩尔比1∶1被包合在辅料空腔中,包合物体系被成功制备且明显提高了药物的体外溶出速率。结论 IMC/HP-β-CD和IMC/AG包合物对IMC均有良好的增溶效果。     

Effect of the labour roadmap on anxiety,labour pain,sense of control,and gestational outcomes in primiparas

Background and purposeThe pain and uncertainty of the labour process can lead to anxiety. Birth ball exercises are one of the pain relief methods for the labour process. This study aimed to explore the outcomes of the use of the labour roadmap with birth balls in primiparas.Materials and methodsThis randomized controlled trial involved Chinese women between the gestational ages of 37–42 weeks who were randomly assigned to the experimental or control group. The outcomes of labour pain, anxiety, and self-control were collected using the Short-Form McGill Pain Questionnaire, visual analogue scale-anxiety, and Labor Agentry Scale, respectively.ResultsThe study found improvements in anxiety, pain, and self-control (P < 0.05), as well as the duration of the first stage of labour (P < 0.05) in the intervention group, but there were no significant differences in the duration of the second and third stages of labour, volume of bleeding, or the 1-min Apgar score between the two groups (P = 0.09, 0.07, 0.06, 0.63, respectively).ConclusionThe labour roadmap was effective for improving self-control, reducing pain and anxiety during labour, and accelerating the first stage of labour.     

真菌球型真菌性鼻窦炎的CT特征及诊断

目的探讨真菌球型真菌性鼻窦炎的CT特征及其在临床中的诊断意义。方法选择2006年8月～2008年5月行鼻内镜手术治疗并经组织病理学检查证实为真菌球型真菌性鼻窦炎的25例患者,对其临床资料及影像学资料进行总结,并以组织病理学结果作为标准分析评价CT扫描对真菌球型真菌性鼻窦炎的诊断价值。结果24例（96%）均为单侧单窦病变,1例（4%）为双侧单窦病变;上颌窦占92%,蝶窦占8%。真菌球型真菌性鼻窦炎CT表现：病变鼻窦内全部充满软组织密度影,密度不均匀的软组织影53.8%,密度均匀的软组织影46.2%;钙化斑或点68.0%。病变鼻窦骨质增生硬化100%,病变上颌窦窦口或内侧壁骨质受压吸收破坏72.0%。此外还有上颌窦口阻塞并扩大（72.0%）及液平面、气泡等（32.0%）。鼻窦CT扫描术前诊断的总体准确率为84.0%。结论真菌球在鼻窦CT除表现为特征性的密度不均匀软组织影及钙化斑或点外,还可表现为密度均匀的软组织影,并同时可伴有骨质增生硬化、窦口阻塞并扩大及上颌窦口和（或）内侧壁骨质受压吸收破坏等。CT扫描对真菌球型真菌性鼻窦炎的术前筛选及诊断有着十分重要的作用,但最终确诊仍需依据组织病理学检查。     

两种巩膜瓣切口羟基磷灰石眼座一期植入比较

目的比较半球形巩膜瓣和花瓣样巩膜瓣羟基磷灰石（HA）眼座一期植入的手术效果。方法将43例（43眼）随机分为两组,分别采用半球形巩膜瓣（20眼）和花瓣样巩膜瓣（23眼）均为HA眼座I期植入治疗术后随访6月～1年。结果半球形巩膜瓣HA植入组1眼并发伤口裂开,经药物治疗后14d愈合;花瓣样巩膜瓣HA植入组1眼并发结膜伤口轻度裂开,药物治疗后10d愈合。半球形巩膜瓣组3眼不同程度残留上睑凹陷。花瓣形巩膜瓣组1眼出现残留上睑凹陷。结论巩膜花瓣形切口HA植入,手术方法简便,术中不破坏眼外肌正常位置及眶脂肪,保留后部巩膜,防止植入物后移、并发症少、恢复快。     

分娩球配合音乐在产程中的应用

[目的]观察分娩球配合音乐在产妇第一产程中使用的效果.[方法]随机抽样选择我院2008年4月-2008年7月住院分娩的产妇60例作为观察组,60例为对照组.观察组在临产后子宫收缩间歇期由助产士(师)负责指导产妇坐在分娩球上,室内播放背景音乐;对照组采取自由体位.[结果]观察组产妇疼痛缓解的效果比对照组好,第一产程和总产程比对照组短,经阴道分娩率比对照组高,剖宫产率比对照组低,经比较均有统计学意义(P<0.05).[结论] 应用分娩球配合音乐可缓解疼痛,加速产程进展,提高阴道分娩率,降低剖宫产率.     

The efficacy of cotton ball packing after endoscopic sinus surgery: A prospective,randomized, controlled trial

ObjectiveThe blocking of airflow into sinonasal cavity may decrease postoperative crusting and the development of adhesions. The purpose of this study was to investigate the efficacy of cotton ball packing in patients following endoscopic sinus surgery (ESS).MethodsThirty nine patients with chronic rhinosinusitis requiring the same extent of ESS were included. As a part of postoperative care, the patients were instructed to perform a nasal saline irrigation and apply a nasal spray in each nostril, and then informed to put a cotton ball in a one side of nostril, and the other side was kept to be empty as a control. Patients’ subjective symptoms, patients’ pain while receiving sinonasal cavity debridement, time required to perform debridement, and postoperative wound healing were evaluated.ResultsAlthough cotton ball packing resulted in less discomfort for postnasal drip, rhinorrhea, headache, and facial pain than no packing, there were no statistically significant differences between the groups. The cotton ball packing was associated with significantly less pain on while performing postoperative debridement, therefore less time was needed to perform debridement. The cotton ball packing appears to improve wound healing within the sinus cavities up to 1 month postoperatively.ConclusionThe use of the cotton ball packing after ESS results in significantly less formation of crusts and adhesions, leading to decreasing pain and time during postoperative debridement and promoting faster wound healing.
