Radially polarized beams' phase filtering focal properties based on path integral analysis.

This paper introduces the path integral (PI) to the analysis of radially polarized (RP) beams' tight focusing problem. The PI makes the contribution of each incident ray on the focal region visible and then makes it possible to choose the filter's parameters more intuitively and precisely. Based on the PI, a zero point construction (ZPC) phase filtering method is realized intuitively.

[Comparation and utilization of crop-omics databases].

Omics plays an important role in life sciences, which studies all the components and their interrelations as a whole. The omics databases collected and sorted out the relevant information to support omics research. The crop-omics database, based on the major food crop information, especially on the sequencing information and data mining, is set up to improve the basic research level of crop sciences and production, which potentially benefit our grain stock.

[Surgical repair of ruptured sinus of Valsalva aneurysm to right atrium].

Objectives: To summarize the experience of surgical repair of ruptured sinus of Valsalva aneurysm to right atrium and to compare the difference between through right atrium repair and transaortic combined with right atrium approach.

Methods: Between January 2004 and December 2009, 53 patients with ruptured sinus of Valsalva aneurysm to right atrium underwent surgical repair. There were 35 male and 18 female, aged from 15 to 63 with a mean of (33 ± 9) years.

Identification of a novel lethal fibrillin-1 gene mutation in a Chinese Marfan family and correlation of 3' fibrillin-1 gene mutations with phenotype.

Background: Mutations in the fibrillin-1 gene have been identified in patients with Marfan syndrome (MFS). This study aimed to identify the molecular defects in the fibrillin-1 gene in a Chinese family with Marfan syndrome, accompanied by aortic aneurysms/dissection.

Methods: Two patients and one non-carrier in the family underwent complete physical, ophthalmic, and cardiovascular examinations.

[Rainfall redistribution in subalpine Quercus aquifolioides forest in upper reaches of Minjiang River].

Based on the meteorological data from June to September 2007, the rainfall redistribution in subalpine Quercus aquifolioides forest in the upper reaches of Minjiang River was investigated by permanent plot method. The results showed that the total rainfall outside the forest was 486.7 mm, and the throughfall, stemflow, and canopy interception accounted for 82.

[Long term outcome after pulmonary thromboendarterectomy].

Objective: To evaluate the long term effect of pulmonary thromboendarterectomy (PTE) in patients with chronic thromboembolic pulmonary hypertension (CTEPH).

Methods: From Mar 1997 to Jun 2002 at Fuwai Hospital, 14 patients with CTEPH underwent PTE and survived. One of them lost contact and the remaining 13 patients were followed up for a mean of 40 (17 - 77) months.
