3D Reconstruction Method based on Medical Image Feature Point Matching.

Medical 3D image reconstruction is an important image processing step in medical image analysis. How to speed up the speed while improving the accuracy in 3D reconstruction is an important issue. To solve this problem, this paper proposes a 3D reconstruction method based on image feature point matching.

[The study on the value of using the chronic obstructive pulmonary disease and asthma physiology score to assess the severity of acute exacerbation in patients with chronic obstructive pulmonary disease complicated by type II respiratory failure].

Objective: To explore the value of the chronic obstructive pulmonary disease (COPD) and asthma physiology score (CAPS) in evaluating the severity and prognosis of patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD) complicated by type II respiratory failure.

Methods: Eighty-two cases with AECOPD complicated by type II respiratory failure between January 2005 and March 2009 were retrospectively analyzed. The severity in survivors and non-survivors was evaluated by CAPS and acute physiology and chronic health evaluation system (APACHE II score, APACHE III score), and retrospective and statistical analyses of all data were performed.

[Candida species distribution in the patients with high risk of deep fungal infections and relevant risk factors: a prospective cohort study].

Objective: To study the distribution of Candida spp. in the patients with high-risk of fungal infection and the risk factors of deep candidiasis.

Methods: A prospective cohort study was performed among 440 consecutive hospitalized patients admitted to the hematology wards, geriatric wards, and ICUs from May 2004 to April 2005.

N-(2-Formamido-eth-yl)formamide.

The complete molecule of the title compound, C(4)H(8)N(2)O(2), is generated by a crystallographic inversion center. The occurence of N-H⋯O hydrogen bonds results in the formation of a two-dimensional infinite network parallel to the (010) plane. In this plane, the hydrogen bonds define graph-set motif R(4) (4)(22) in a centrosymmetric array by the association of four mol-ecules.
