Protecting the Lithium Metal Anode for a Safe Flexible Lithium-Air Battery in Ambient Air.

The flexible Li-air battery (FLAB) with ultrahigh energy density is a hopeful candidate for flexible energy storage devices. However, most current FLAB operate in a pure oxygen atmosphere, which is limited by safety and corrosion issues from the metallic lithium anode and has thus greatly impeded the application of FLAB. Now, inspired by the protection effect of the umbrella, a stable hydrophobic composite polymer electrolyte (SHCPE) film with high flexibility, hydrophobicity, and stability was fabricated to protect the lithium anode.

An Illumination-Assisted Flexible Self-Powered Energy System Based on a Li-O Battery.

The flexible Li-O battery is suitable to satisfy the requirements of a self-powered energy system, thanks to environmental friendliness, low cost, and high theoretical energy density. Herein, a flexible porous bifunctional electrode with both electrocatalytic and photocatalytic activity was synthesized and introduced as a cathode to assemble a high-performance Li-O battery that achieved an overpotential of 0.19 V by charging with the aid of solar energy.

[Combined use of occluder plus bare stent in the treatment of aortic dissection with tear at the area of visceral branches].

Objective: To evaluate the novel method of combinedly use of occluder and bare stent in the treatment of aortic dissection with distal tear at visceral branches.

Methods: From April 2010 to September 2012, 6 patients (5 male and 1 female patients, aged from 29 to 62 years, mean 47.2 years) were diagnosed as Stanford type B aortic dissection that been revealed by CT angiography.

[Assessment of hepatic reserve function of cirrhosis liver using dynamic SPECT (99m)Tc-galactosyl human serum albumin scintigraphy].

Objective: To evaluate the effectiveness of dynamic SPECT (99m)Tc-galactosyl human serum albumin (GSA) scintigraphy on the assessment of reserve function of cirrhosis liver.

Methods: From January 2010 to December 2011, 55 patients with cirrhosis liver were enrolled in this study. The case numbers of male and female were 43 and 12 respectively and the age was (51 ± 9) years (ranging from 35 to 69 years).

The influence of interpreters' professional background and experience on the interpretation of multimodality imaging of pulmonary lesions using 18F-3'-deoxy-fluorothymidine and 18F-fluorodeoxyglucose PET/CT.

Objective: Based on the results of a recently accomplished multicenter clinical trial for the incremental value of a dual-tracer (18F-FDG and 18F-FLT), dual-modality (PET and CT) imaging in the differential diagnosis of pulmonary lesions, we investigate some issues that might affect the image interpretation and result reporting.

Methods: The images were read in two separate sessions. Firstly the images were read and reported by physician(s) of the imaging center on completion of each PET/CT scanning.

[Application of inferior vena cava filters in prevention of peri-operative pulmonary embolism in patients with bone fracture combined with deep venous thrombosis: a report of 572 cases].

Objectives: To evaluate the application of inferior vena cava filter (IVCF) in prevention of peri-operative pulmonary embolism in patients with bone fracture combined with deep venous thrombosis (DVT).

Methods: From July 2007 to April 2011, 572 cases of bone fractures consequent with DVT that confirmed by Duplex were deployed IVCF to avoid fatal pulmonary embolism in the para-operative period. There were 318 male and 254 female patients with a mean age of (51±23) years (ranging from 16 to 94 years).

Review of clinical investigation on recurrence of gastric cancer following curative resection.

Objective: To discuss the present status and progress of clinical research on recurrence of gastric cancer after surgery, including patterns, clinicopathologic factors, prognosis, detection, diagnosis, prevention, and treatment strategies.

Data Sources: The data used in this review were mainly from PubMed articles published in English from 2000 to August 2011. The search terms were "gastric cancer" and "recurrence".

Predictive factors improving survival after gastric and hepatic surgical treatment in gastric cancer patients with synchronous liver metastases.

Background: The prognosis for patients with gastric cancer and synchronous liver metastases is very poor. However, a standard therapeutic strategy has not been well established. The clinical benefit and prognostic factors after hepatic surgical treatment for liver metastases from gastric cancer remain controversial.
