Treatment of severe diffuse cavernous hemangioma of the lower limb by combination of superficial femoral

Yin XIA, Dan SHANG, Qin LI, Xiaoqin RUN, Chenxi OUYANG, Yiqing LI, Bi JIN

《医学前沿（英文）》 2009年 第3卷 第2期   页码 240-244 doi: 10.1007/s11684-009-0031-8

摘要： Severe diffuse cavernous hemangioma of the lower limb is rarely seen among young people and sometimes can be a fatal challenge for operation. We reported a case of diffuse cavernous hemangioma involving both skin and muscles of the left lower limb and perineal region in an adolescent patient. The patient who had previously undergone a local hemangioma resection of the foot ultimately ended in superficial femoral artery ligation and supergenual thigh amputation of the left upper leg because of uncontrollable massive bleeding of anastomotic stoma.

The investigation of pressure drop in moving-beds

CHEN Yunhua, ZHU Xuedong, WU Yongqiang, ZHU Zibin

《化学科学与工程前沿（英文）》 2007年 第1卷 第2期   页码 184-189 doi: 10.1007/s11705-007-0034-4

摘要： The pressure drop of a cross-flow moving-bed was investigated in a two-dimensional rectangular apparatus. The effects of the particle velocity, the superficial gas velocity, the formation and development of cavity/raceway and voidage of particles on the pressure drop were investigated experimentally under the operational conditions of 0.09 1.35 m/s of the superficial gas velocity and 0.95 9.68 cm/min of the particle velocity. The experimental results show that the particle velocity has little influence on the pressure drop, while the phenomena of cavity and pinning occur when the cross-flow velocity is high enough. The development of a cavity or a raceway can result in three types of variations of pressure drop with time: stabilization, slight fluctuation and severe fluctuation. A cavity appears in a process cycle of formation-growing up-collapsing-fluidization at a high gas velocity. On the basis of experimental results, a model for calculating the pressure drop after a cavity occurs and a dimensionless relationship of cavity size is developed, which gives a good qualitative account of the experimental data.

摘要： The study evaluated the value of ultrasound elastography in differentiating the benign and malignant superficial lymph nodes. A total of 112 subjects, including 82 patients with enlarged lymph nodes and 30 healthy volunteers, were recruited. All the subjects were examined by B-mode ultrasonography, power Doppler ultrasonography and elastography. Most of the patients were histopathologically confirmed by needle aspiration cytology and some patients were diagnosed by clinical data combined with follow-up findings. The sensitivity, specificity and accuracy of B-mode ultrasonography were 59.8%, 76.5% and 67.1%, those of the blood flow classification by power Doppler ultrasonography 77.0%, 82.3% and 79.4% and those of elastographic classification 74.7%, 97.1% and 84.5%, respectively. The elasticity of the lymph nodes was quantitatively measured and defined as stiffness value. When the stiffness value of 2.395 was taken as the cutoff point, the sensitivity and specificity of elastography were 78.41% and 98.51%, and the Youden index reached the highest, with the value being 0.7692. The stiffness values of two indeterminate benign lymph nodes, the elastrographic findings of which were rated as patterns 2 and 3, were below the cutoff point. The elastographic findings of 10 malignant lymph nodes were also classified as pattern 2 or 3. Only one of them had the stiffness values below the cutoff point. It was concluded that ultrasound elastography is a novel, noninvasive and convenient tool for the differentiation of the nature of the superficial lymph nodes in clinical practice.

摘要： A referral patient who had previously undergone varicose vein surgery was admitted as an emergency case. On admission, the patient complained of intolerable pain, paralysis and paresthesia of the affected limb, which was characterized by acute arterial ischemia symptoms. Color Doppler of the artery of the affected limb indicated that no blood flow signal existed in the superficial femoral artery. During exploratory operation, we found that the right superficial femoral artery instead of the great saphenous vein of the affected limb had been stripped and ligated. Therefore, the intact right great saphenous vein was taken for auto-transplantation by inverse end-to-end anastomosis to the proximal and distal residual superficial femoral artery, which resulted in gradual recovery. Except for ischemic reperfusion injury, no other post-operative complications occurred after a 10 month follow-up; however, the long-term curative effect needs further observation. Here we report our treatment experience.

Mass transfer mechanisms in fixed-bed adsorption of erythromycin

SUN Ying, ZHU Jiawen, CHEN Kui, ZHU Sheng, XU Jie

《化学科学与工程前沿（英文）》 2008年 第2卷 第4期   页码 353-360 doi: 10.1007/s11705-008-0076-2

摘要： The equilibrium and kinetic characteristics of the adsorption of erythromycin to Sepabeads SP825 were determined. The equilibrium data in a batch system was well described by a Langmuir isotherm. The separation performance was investigated in a fixed-bed system with respect to the adsorption superficial velocity, ionic strength and pH. A mathematical model was used to simulate the mass transfer mechanism, taking film mass transfer, pore diffusion and axial dispersion into account. The model predictions were consistent with the experimental data and were consequently used to determine the mass transfer coefficients.

Experimental study for the stratified to slug flow regime transition mechanism of gas-oil two-phase flow in horizontal pipe

LIU Yiping, YANG Weilin, WANG Jing

《能源前沿（英文）》 2008年 第2卷 第2期   页码 152-157 doi: 10.1007/s11708-008-0012-7

摘要： Theoretical relations that predict the transition from a stratified pattern to a slug pattern, including a one-dimensional wave model that contains less empiricism than the commonly used Taitel-Dukler model, and the ideal model for stratified flow for the gas-liquid flow in horizontal pipes are presented. Superficial velocities of each phase, as the onset of slugging occurs, were predicted, and theoretical analysis was conducted on the stratified to slug flow regime transition. The friction, existing between the fluid and pipe wall, and on the interface of two phases, was especially taken into account. A theoretical model was applied to an experiment about air-oil two-phase flow in a 50 mm horizontal pipe. The effect of pipe diameter on the transition was also studied. The results show that this approach gives a reasonable prediction over the whole range of flow rates, and better agreement has been achieved between predicted and measured critical parameters.
