AMPK在妊娠期糖尿病发病机制中的作用

腺苷酸活化蛋白激酶是一种重要的蛋白激酶,主要作用是协调代谢和能量平衡.腺苷酸活化蛋白激酶被激活后,在增加骨骼肌对葡萄糖摄取、增强胰岛素敏感性、增加脂肪酸氧化以及调节基因转录等方面发挥重要作用.已经证实脂联素有调节糖脂代谢的作用,但其作用机制尚不十分清楚,很可能是通过腺苷酸活化蛋白激酶介导,对脂联素信号转导通路的研究将成为进一步理解脂联素作用的关键所在.而脂联素又是妊娠期糖尿病的预测因子,所以腺苷酸活化蛋白激酶逐渐成为对妊娠期糖尿病研究中的焦点.     

Surveillance of congenital cytomegalovirus disease, 1990-1991. Collaborating Registry Group.

In January 1990, a registry was initiated for surveillance of infants with the often severe symptoms of congenital cytomegalovirus (CMV) disease. In the first 2 years, 100 cases were reported to the registry. Petechiae, the most commonly noted clinical sign, were reported for approximately 50% of infants, usually accompanied by hepatomegaly and splenomegaly. Of the various severe neurologic conditions that can result from congenital CMV infection, the most frequent was intracranial calcifications, which were noted in 43% of the cases. The most common laboratory abnormality was low platelet count, which was observed in 52% of the cases. Infants with severe neurologic damage were about twice as likely as infants with less severe damage to have most other clinical signs and laboratory abnormalities. Databases will be developed to facilitate comparisons among symptomatically infected infants and asymptomatically infected as well as noninfected infants.     

Partners in Growth: Implementing Family-Centered Changes in the Neonatal Intensive Care Unit

Although there are several forces driving changes with regard to parents within neonatal intensive care units (NICUs), they all culminate in the ideals represented in family-centered care. This article examined the variables that are perceived by parents to be barriers to their assumption of parental roles while their infants were hospitalized in the NICU. Data were used to support and implement pragmatic changes in program development and service delivery within the NICU.     

臂丛神经根性损伤膈神经移位术对青壮年患者早期呼吸功能的影响

目的研究臂丛神经损伤膈神经移位术对青壮年患者早期呼吸功能的影响.方法对16例接受膈神经移位治疗的患者,在术前、术后（10 d）进行肺功能指标的比较,同时定期进行门诊随访,观察呼吸系统自觉症状程度.结果13例术后出现了不同程度的供氧不足症状,16例全部出现一侧膈肌抬高,术后第10天肺活量（VC）、肺活量预计值百分数（VC%）分别比术前减少37.98%和26.88%,两者差异有统计学意义（tvc=11.532、tvc%=0,P＜0.01）.其它项目如残气量（RV）较术前轻度下降,肺总量（TLC）下降值达到术前肺总量的36.49%,残气量/肺总量比值（RV/TLC%）较术前上升了4.75%,上述各指标的差值均有统计学意义.1 s用力呼气量/用力肺活量比值（FEV1/FVC）和术前比基本无改变,但其差值有统计学意义.膈神经移位右侧（10例）与左侧（6例）术前、术后肺活量比较差异有统计学意义.术后随访8个月～2年,所有患者均无明显呼吸困难和胸闷等症状.结论膈神经移位术后对青壮年患者肺容量有较大的丧失,肺通气功能减弱和小气道阻力增加,但其丧失程度在机体自身代偿耐受范围内,不会导致急剧发生的严重呼吸功能障碍.建议对右侧臂丛神经根性损伤的患者,术前进行严格的肺、心功能检查,避免发生较为严重的并发症.     

A case of subcortical grey matter heterotopia presenting as bipolar disorder.

A case of previously diagnosed bipolar disorder was found to be associated with unilateral subcortical grey matter heterotopia, cortical hemiatrophy, midline shift, and ventriculomegaly on magnetic resonance imaging (MRI). The patient responded to pharmacotherapy with lithium carbonate and carbamazepine. This case dramatically illustrates the need for neuroimaging in psychiatric patients with apparently "functional" affective illness.     

Determination of pipothiazine in human plasma by reversed-phase high-performance liquid chromatography

A method is described for the determination of pipothiazine in human plasma, based on reversed-phase HPLC. The method has been applied in a pharmacokinetic study of pipothiazine in six psychiatric patients receiving repeated depot intramuscular injections for six months. A number of compounds likely to be taken concurrently by patients were tested for potential to interfere with the assay. There was no evidence of "dose-dumping" in the period following injection. Comparison of the pharmacokinetic profiles after the first and sixth injections showed no evidence of drug accumulation.     

An Analytic Model of Subminiature Auditory Sensation System for Sound Source Localization

It is reported that some types of insects have a remarkable ability to detect the direction of an incident sound even though its acoustic sensory organs are in very close proximity each other. Maybe the ears are jointed by a cuticular structure with which the separated motions can be coupled mechanically and thus be magnified. In this paper, a detailed model is setup to describe the principle of this type of localization using a mechanical coupled structure. The transfer functions and the responses of the model in terms of time and frequency are analyzed to describe the mechanism of its ability of directional hearing. This analytical model provides a method to design the experimental model for the predetermined incident sound pressure, and the analysis of this model shows that this structure have the ability to determine the direction of the incident stimulus.
