AIM:To examine which anesthesia general or local is more effective for penetrating keratoplasty(PKP).METHODS:Patients with indications for PKP(n=141)were enrolled in a prospective study and randomly divided into general anesthesia group(group A,70 eyes)and local anesthesia group(group B,71 eyes).Patients received optical PKP(group A1,30 eyes;group B1,30eyes)or therapeutic PKP(group A2,40 eyes;group B2,41 eyes).Measurement of anterior chamber treatment time(T)for PKP patients and the ratio(R)of the area of the pupils to that of recipient graft region.T and R values,as well as perioperative and postoperative complications,were compared between groups A and B using t-test orχ***:Patients were followed for 2wk after PKP.T was(13.45±8.64)min for group A and(7.36±5.24)min for group B,a statistically significant difference(P<0.001).The R value for group A was stable during the operation,while for PKP patients in group B the value initially increased then gradually decreased to normal after *** group B,extrusion of intraocular contents occurred in 5 eyes,and iridal prolapse occured in 11cases;no perioperative complications occurred in group *** rate for fungal keratitis was 13.04%in group B and 0%in group ***:Under general anesthesia,pupils remaine stable during PKP and perioperative complications are *** anesthesia gives more time to treat pathological changes in the anterior chamber and treatment success rate is higher.

Science in China,Ser.B 1983年第6期26卷 648-661页

作者：姚伯初王光宇 no.2 Marine Geological Investigation Brigade Ministry of Geology and Mineral Resources Guangzhou

Based on the results from prospcction of seismic sonobuoy and two-ship refraction measurement, structural characteristics for earth crust of South China Sea Basin are analyzed: very thick crustal Layer 1, normal crustal Layer 2 and abnormally thin crustal Layer 3 are observed, with Layer 3 increasing continuously in thickness towards NS direction from the centre of the basin, and the earth crust becoming thick accordingly. These structural characteristics are in conformity with Cenozoic sea spreading mode inferred from magnetic anomaly. Finally, possible causes that account for these characteristics are discussed.

Hemodynamic effects of the spiral flow guider on small-diameter vascular graft

引用

水动力学研究与进展（A辑） 2015年第6期30卷 685-691页

作者： ZHANG Zhi-guo ZHU Ming ZHANG Ming SHI Xiao-hao DENG Lin-hong Institute of Biomedical Engineering and Health Sciences Changzhou University Thoracic and Cardiovascular Surgery Changzhou NO.2 Hospital

Small-diameter vascular grafts are in large demand for coronary and peripheral bypass procedures, but present products still fail in long-term clinical application. Hence, A new type of small-diameter vascular graft(SDVG) is designed with a spiral flow guider to induce spiral blood flow and thus improve the local hemodynamic performance. In present article, to investigated how the spiral flow guider influenced the hemodynam ic performance of this new SDVG, via computational fluid dynamics(CFD). The numerical results demonstrate that: 1) the spiral flow guider could indeed make the blood flow rotate; 2) the blood velocity near the vessel wall and wall shear rate(WSR) w ere greatly enhanced; 3) the number of the helical turns had obvious non-positive correlation with the hemodynamic performan ce of the new graft. It is believed that the increased blood velocity near the wall and the WSR are conductive to anti-throm bosis and anti-hyperplasia, hence the graft patency rate for long-term clinical use can be improved. Present study may also h elp better understand the optimal design of the spiral flow guider for the purpose of prolonging the long-term patency rate of th e SDVG.

An Exploration into the West Henan Large Sliding Structure in the South of the North China Plate

引用

Acta Geologica Sinica(English Edition) 2000年第2期74卷 241-245页

作者： LIU Chuanxi no.2 Party Henan Coalfield Geological Bureau100 Longmen RoadLuoyang 471023Henan

The West Henan large sliding structure is located in the southern part of the North China plate. It is a planar structural feature of a relatively large scale. To its northwest lie the Taihang Mountains, and to the southwest the Funiu Mountain. In the east it extends between the broad plain and hilly land. Formed in the early Indosinian Period, its main sliding surface is the coal seam II|, with the sliding direction from NW to SE, and a sliding area of about 23,000 km2. Affected by the big sliding, the coal seam II|, in West Henan occurs in the state of powder, and thickens to the SE. Some small penetrating sliding structures were developed over II| in the early Yanshanian Period, causing a disorder on the south border of the North China coal-accumulating basin in the late Palaeozoic Era. An exploration into the West Henan large sliding structure is of great importance in the geological study.
