Background Delirium is a common and deleterious complication in critically ill patients after surgery. The purpose of this study was to determine the incidence and risk factors of delirium in critically ill patients after non-cardiac surgery, and to investigate the relationship between the serum cortisol level and the occurrence of postoperative delirium. Methods In a prospective cohort study, 164 consecutive patients who were admitted to the surgical intensive care unit after non-cardiac surgery were enrolled. Baseline characteristics and perioperative variables were collected. Blood samples were obtained on the first postoperative day and serum cortisol concentrations were measured. Delirium was assessed using the Nursing Delirium Screening Scale until the seventh postoperative day or the disappearance of delirious symptoms. Results Postoperative delirium occurred in 44.5% of patients （73 of 164）. The median time to first onset of delirium is 0 （range 0 to 5 days） and the median duration of delirium is 3 （1 to 13） days. Independent risk factors of postoperative delirium included increasing age （odds ratio （OR） 2.646, 95% confidence interval （C/） 1.431 to 4.890, P=-0.002）, a history of previous stroke （OR 4.499, 95%C/1.228 to 16.481, P=-0.023）, high Acute Physiology and Chronic Health Evaluation II score on surgical intensive care unite admission （OR 1.391, 95%C/1.201 to 1.612, P 〈0.001）, and high serum cortisol level on the 1st postoperative day （OR 3.381, 95%CI 1.690 to 6.765, P=-0.001）. The development of delirium was linked to higher incidence of postoperative complications （28.8% vs. 7.7%, P 〈0.001）, and longer duration of hospitalization （18 （7 to 74） days vs. 13 （3 to 48） days, P 〈0.001）. Conclusions Delirium was a frequent complication in critically ill patients after non-cardiac surgery. High serum cortisol level was associated with increased incidence of postoperative delirium.

Rheumatic heart disease is still highly prevalent in .developing countries where the incidence of coronaryartery disease （CAD） is also arising. Consequently the occurrence of coexistent CAD and mitral stenosis （MS） dominantly caused by rheumatic fever is more frequent in these countries. Comorbidities such as pulmonary and renal dysfunction occur frequently in these aging populations. Off-pump surgery is widely applied in patients with concomitant CAD and severe comorbidities due to lower incidence of postoperative morbidity. Closed mitral commissurotomy （CMC） is a well established treatment for patients with mitral stenosis. We report here a case of moderate stenosis combined with seriously diffuse 3-vessel CAD and severe chronic obstructive pulmonary disease （COPD） in an elder male treated with off-pump coronary artery bypass （OPCAB） plus CMC.

Background The temporal response to off-pump anteroapical aneurysm plication has not been well defined. We have evaluated the long-term clinical and functional results of this technique and compared the efficacy with the patch modeling repair. Methods From March 2005 to May 2010, 163 （115 men and 48 women） consecutive patients were operated on for post-infarction left ventricular aneurysm （LVA）, 54 patients underwent patch remodeling （group A） and 109 patients underwent off-pump anteroapical aneurysm plication repair （group B）. All patients had simultaneous coronary revascularization, other operative procedures included septoplasty in eight and ablation of ventricular tachycardia in six. Follow-up ranged from 1 to 5 years, short-term and mid-term outcomes, including complications, cardiac function, and mortality, were assessed. Results Early mortality was 1.8% for all patients （group A 1 death vs. group B 2 deaths, not significant （NS））. Peri-operative support included intraaortic balloon pumping in 16 （9.8%）, （group A 6 patients vs. group B 10 patients, NS） and inotropic drugs in 84 （51.5%）, （group A 34 vs. group B 50, NS）. During a mean follow-up of （3.7±0.8） years, eight patients died, with four due to cardiac-related causes. No patient required transplantation, and two required use of an implantable cardioverter-defibrillator for ventricular tachycardia. Survival at 1 and 5 years was 95% and 86%, respectively. It did not differ significantly between group A and group B. Functional class improved from 2.90±0.59 to 1.65±0.54 among the mid-term survivors （P 〈0.001）, with no significant difference between the two groups. Pre-operative risk factors for mortality or poor function were ejection fraction （EF）〈0.35 （OR=7.9, 95% CI 1.6-40.0）; congestive heart failure （CHF）（OR=4.4, 95% CI 1.0-19.0）; end-systolic volume index （ESVI）〉80 ml/m2 （OR=3.7, 95% CI 1.0-14.0）; and advanced age 〉70 years （OR=2.4, 95% CI 1.0-12.0）.

The perforating phase leads to complex and diverse hydraulic fracture propagation behaviors in laminated shale formations. In this paper, a 2D high-speed imaging scheme which can capture the interaction between perforating phase and natural shale bedding planes was proposed. The phase field method was used to simulate the same conditions as in the experiment for verification and hydraulic fracture propagation mechanism under the competition of perforating phase and bedding planes was *** results indicate that the bedding planes appear to be no influence on fracture propagation while the perforating phase is perpendicular to the bedding planes, and the fracture propagates along the perforating phase without deflection. When the perforating phase algins with the bedding planes, the fracture initiation pressure reserves the lowest value, and no deflection occurs during fracture propagation. When the perforating phase is the angle 45°, 60°and 75°of bedding planes, the bedding planes begin to play a key role on the fracture deflection. The maximum deflection degree is reached at the perforating phase of75°. Numerical simulation provides evidence that the existence of shale bedding planes is not exactly equivalent to anisotropy for fracture propagation and the difference of mechanical properties between different shale layers is the fundamental reason for fracture deflection. The findings help to understand the intrinsic characteristics of shale and provide a theoretical basis for the optimization design of field perforation parameters.

We present a study of the dwarf elliptical galaxy NGC 855 using the narrow-band Hα and Spitzer data. Both the Hα and Spitzer IRAC images confirm star-forming activity in the center of NGC 855. We obtained a star formation rate （SFR） of 0.022 and 0.025Mo yr^-1, respectively, from the Spitzer IRAC 8.0 μm and MIPS 24 #m emission data. The HI observation suggests that the star-forming activity might be triggered by a minor merger. We also find that there is a distinct IR emission region in 5.8 and 8.0 μm bands, located at about 10＂ away from the nucleus of NGC 855. Given the strong 8.0 μm but faint Hα emission, we expect that it is a heavily obscured star-forming region, which needs to be confirmed by further optical spectroscopic observations.
