AIm： To investigate the correlation between systemic hemodynamics and splanchnic circulation in recipients with cirrhosis undergoing living-donor liver transplantation （LDLT）, and to clarify how systemic hemodynamics impact on local graft circulation after LDLT.mETHODS： Systemic hemodynamics, indocyanine green （ICG） elimination rate （K,cG） and splanchnic circulation were simultaneously and non-invasively investigated by pulse dye densitometry （PDD） and ultrasound. Accurate estimators of optimal systemic hyperdynamics after LDLT [i.e., balance of cardiac output （CO） to blood volume （BV） and mean transit time （mTT）, defined as the time required for half the administered ICG to pass through an attached PDD sensor in the first circulation] were also measured. Thirty recipients with cirrhosis were divided into two groups based on clinical outcomes corresponding to postoperative graft function.RESULTS： Cirrhotic systemic hyperdynamics characterized by high CO, expanded BV and low total peripheral resistance （TPR） were observed before LDLT. TPR reflecting cirrhotic vascular alterations was slowly restored after LDLT in both groups. Although no significant temporal differences in TPR were detected between the two groups, CO/BV and m＇IT differed significantly. Recipients with good outcomes showed persistent cirrhotic systemic hyperdynamics after LDLT, whereas recipients with poor outcomes presented with unstable cirrhotic systemic hyperdynamics and severely decreased KICG. Systemic hyperdynamic disorders after LDLT impacted on portal venous flow but not hepatic arterial flow.CONCLUSION： We conclude that subtle systemic hyperdynamics disorders impact on splanchnic circulation, and that an imbalance between CO and BV decreases portal venous flow, which results in critical outcomes.

Calcitriol-induced hypercalcemia in a patient with granulomatous mycosis fungoides and end-stage renal disease

World Journal of Nephrology 2013年第2期2卷 44-48页

An 86-year-old man, diagnosed as having mycosis fungoides in may 2008 and treated with repeated radiation therapy, was admitted to our hospital for initiation of hemodialysis due to end-stage renal disease(ESRD) in April 2012. On admission, his corrected serum calcium level was 9.3 mg/d L, and his intact parathyroid hormone level was 121.9 pg/mL(normal range 13.9-78.5pg/mL), indicating secondary hyperparathyroidism due to ESRD. After starting hemodialysis, urinary volume diminished rapidly. The serum calcium level increased(12.7 mg/dL), and the intact parathyroid hormone level was suppressed(m L), while the 1,25-dihy-droxyvitamin D3(calcitriol) level increased(114 pg/mL, normal range: 20.0-60.0 pg/m L) in June 2012. The possibilities of sarcoidosis and tuberculosis were ruled out. Skin biopsies from tumorous lesions revealed a diagnosis of granulomatous mycosis fungoides. The serum soluble interleukin-2 receptor levels and the degrees of skin lesions went in parallel with the increased serum calcium and calcitriol levels. Therefore, the patient was diagnosed as having calcitriol-induced hypercalcemia possibly associated with granulomatous mycosis fungoides. Granulomatous mycosis fungoides is rare, and its association with calcitriol-induced hypercalcemia has not been reported. Careful attention to calcium metabolism is needed in patients with granulomatous mycosis fungoides, especially in patients with ESRD.

Differential and total cross sections of the γp→π0p and the γd→π0pn reaction were measured for photon energies between 640 and 1 150 meV. The data have been compared with SAID and mAID model calculations. π0 photoproduction on the deuteron shows a strong suppression of the 2nd resonance which is clearly seen in the γp→π0p reaction.

2003年9月25日(世界时)十胜近海地震(m_w～8.0)随后的GPS时间序列揭示出了显著形变。我们采用“网络反演滤波”技术,对震后30天内后续断层滑动的时空演变进行了反演。后续断层滑动集中在同震破裂带附近,即在2003年地震断裂带、1968年十胜近海地震和1973年根室近海地震震源区之间的位置。反演表明,2003年地震断裂带中断层滑动速率衰减迅速,而周围地区衰减速度较慢。后续断层滑动地区的应力一速度路径大致遵循dr/d 1n(v)～0.6 mPa,这暗示着稳态速度强化摩擦。尽管不能排除其他的解释,但在沿走向的方向上,同震破裂和后续断层滑动互补的空间模型还是可能表明了摩擦特征的空间变化。

为了研究西太平洋地区的构造形变特征,在此建立了一个连续的GPS跟踪网络,并命名为西太平洋整体GPS网络(WING)。1995年至1997年3月该网共建有10个新站点。我们利用该网1995年7月到1996年10月的观测资料和国际GPS地球动力学服务(IGS)全球站的数据来估算各站点的日坐标,并采用自由基准方法以获取最优基线解。为了将估算的坐标归算到地球参考框架上,我们根据Heki(1996)的估算结果,假设筑波IGS站点正相对稳定的欧亚板块以约2cm/a的速度向西运动。我们发现:(1)海洋板块内各站点的运动速度与刚性板块运动模型吻合得很好;(2)板块边界附近站点的运动受到板块边界形变的影响。在这些板块边界中,马里亚纳和冲绳海沟的弧后隆起(扩张)清晰可辨;(3)位于东亚地区的各站点正相对稳定的欧亚板块向东到东南方向运动,反映了印度板块和亚洲板块北向碰撞的长距离效应。
