成本核算在医院管理中的应用和进展

目前,我国医疗总费用的增长速度大大超过了国民经济和财政收入的增长速度[1]。卫生经费投入不足,药费居高不下,政府、企业不堪重负,医疗制度改革势在必行。成本核算是医院经济管理的基础工作,核算工作的深度和层次直接影响医院成本管理的成效。1医疗成本核算的概念医疗成本是卫生服务过程中所发生的物化劳动和活劳动耗费的总和。它由以下6大类成本构成:劳务费、业务费、公务费、原材料费、固定资产折旧费和管理费。医疗成本核算是按照《医院财务制度》有关成本费用开支范围的规定,核算医院在医疗服务过程中所支出的物质消耗、劳务报酬以及有…

Interactions between membrane IgM and the cytoskeleton involve the cytoplasmic domain of the immunoglobulin receptor

Cross-linking induced interactions between the membrane form of immunoglobulin (mIg) and the cytoskeletal matrix have been described by several groups. To date, the function of mIgM association with the cytoskeleton is not yet understood. Delineation of the molecular basis of these interactions will be instrumental in elucidating their function. We have previously shown that the Igα/β heterodimer is not required for ligand-induced mIgM binding to the cytoskeleton. In this study, we have investigated the role of other B cell-specific proteins in mediating these interactions. For this, we expressed mIgM in the non-hematopoietic human cervical carcinoma cell line HeLa S3 and verified the capacity of the surface-expressed IgM to interact with the cytoskeletal matrix upon cross-linking with anti-μ chain antibodies. We show here that only the mIgM molecule itself and no other B cell-specific protein(s) is required in mediating mIgM interactions with actin filaments. In an attempt to determine the cytoskeleton-binding site of mIgM we investigated the role of the cytoplasmic tail of mIgM (KVK) in binding the receptor to actin-based microfilaments. Using mutated forms of mIgM expressed in J558L cells, we show here that KVK plays a role in mediating these interactions. The absence of KVK did not, however, completely abrogate mIgM-cytoskeletal interactions, suggesting that there are additional molecular requirements for the ligand-induced mIgM binding to the cytoskeletal matrix.

脐带夹对防止脐部感染和出血的临床与实验研究

目的应用国产脐带夹用于农村山区破伤风高发区，并经离体试验验证其可靠性。方法经湖南、江西、广西等省基层接生员临床应用、并与当地同期或前一年未用夹者进行对照；同时经离体脐带用脐带夹、气门芯或纱线结扎阻断血管后进行金黄色葡萄球菌和破伤风毒素通透试验以及测试承受气压程度试验。结果1年临床使用2296例中，无1例发生破伤风和败血症。可靠性试验结果证明，粗纱线结扎最差，气门芯虽优于前者，但不如脐带夹。结论该脐带夹由于夹持力持久有力，细菌、毒素难以通过、安全可靠，因此能降低新生儿“病从脐入”的发病率和死亡率，有利干优生优育的贯彻．这是一项花费少、收效大的简而易行的适宜技术，值得推广。     

Involvement of NMDA and NonNMDA Receptors in Motor Task--related Activity in the Primary and Secondary Cortical Motor Areas of the Monkey

The involvement of the NMDA and non-NMDA receptors in the task-relatedneuronal activity of the primary motor cortex (MI), premotorcortex (PM), supplementary motor area (SMA), and an area rostralto the SMA (pre-SMA) of two monkeys (Macace fuscata) was examinedduring performance of a trained motor task. The selective NMDAantagonist 0-2-amino-5-phosphonovaleric acid (APV) and the non-NMDAantagonist 6-cyano-7-nitroquinoxaline-2,3-dione (CNQX) wereiontophoretically applied to motor task-related neurons. A totalof 568 task-related neurons (435 movement related, 83 set related,50 mixed type) were recorded from the MI, PM, SMA, and pre-SMA,and the effects of APV and CNQX were examined in the individualneurons. In many neurons, APV selectively or preferentiallysuppressed the spontaneous discharge rather than movement-relatedactivity. In many neurons, the movement-related activity wasmore selectively or effectively suppressed by CNQX than by APV.However, the set-related activity was affected by both APV endCNQX. The neurons in layers I and II were affected more stronglyby APV end CNQX than those in layers V and VI. No correlationwas found between the magnitude of task-related activity inthe control (no drug application) period and the effectivenessof APV or CNOX. These results indicate that both NMDA and non-NMDAglutamate receptors are involved in motor task-related neuronalactivity of both primary and secondary motor areas, althoughthe contribution of these two receptors to individual neuronalactivity varies a great deal.
