重视医院信誉 减少无形资产流失

随着市场经济和医院深化改革的不断深入,相继出现了合资医院、股份制医院以及医院集团等多种办院形式,一系列的改革都涉及到医院资产产权变动与重组问题。巳往管理者都注重医院有形资产的管理,巳经有比较完善的管理制度,而对无形资产的管理则较为忽视,尤其对比较重要的无形资产-医院信誉的认识更为薄弱。在新形势下,医院信誉对医院的生存和发展越来越显示出它的重要价值。围绕形资产-医院信誉的重要性、特点和价值以及怎样去维护和发展它提出管理建议。     

新鲜主动脉瓣与肺动脉瓣的解剖学观测及其临床意义

目的：从解剖学方面为自体肺动脉瓣替换主动脉瓣手术提供理论依据。方法：对１１例正常国人新鲜心脏标本的主、肺动脉瓣进行解剖学测量,并对结果进行对比研究。结果：①肺动脉瓣所能承受的压力虽小于主动脉瓣所能承受的压力,但其最小值（２８ｋＰａ）高于正常人体动脉压;②肺动脉瓣及肺动脉窦的各项测量数值均略大于主动脉瓣及主动脉窦,但无统计学意义（Ｐ＞０．０５）。结论：①肺动脉瓣能承受主动脉瓣位置的压力;②主、肺动脉瓣叶及主、肺动脉窦在形态、大小上是匹配的。     

Method for Carotid Artery 3-D Ultrasound Image Segmentation Based on CSWin Transformer

Precise segmentation of carotid artery (CA) structure is an important prerequisite for the medical assessment and detection of carotid plaques. For automatic segmentation of the media–adventitia boundary (MAB) and lumen–intima boundary (LIB) in 3-D ultrasound images of the CA, a U-shaped CSWin transformer (U-CSWT) is proposed. Both the encoder and decoder of the U-CSWT are composed of hierarchical CSWT modules, which can capture rich global context information in the 3-D image. Experiments were performed on a 3-D ultrasound image data set of the CA, and the results indicate that the U-CSWT performs better than other convolutional neural network (CNN)-based and CNN–transformer hybrid methods. The model yields Dice coefficients of 94.6 ± 3.0% and 90.8 ± 5.1% for the MAB and LIB in the common carotid artery (CCA) and 92.9 ± 4.9% and 89.6 ± 6.2% for MAB and LIB in the bifurcation, respectively. Our U-CSWT is expected to become an effective method for automatic segmentation of 3-D ultrasound images of CA.
