An 87-year-old male with old myocardial infarction was referred to the hospital due to left femur neck fracture and intermittent dizziness. Significant 2:1 atrioventricular block was demonstrated on initial electrocardiogram (Figure 1). Transthoracic echocardiography showed reduced left ventricular function (LVEF = 47%) with regional wall motion abnormality of right coronary artery (RCA) and left circumflex coronary artery (LCx) artery. Coronary angiography showed patent previous proximal RCA and distal LCx stents. Temporary pacemaker was inserted initially and the patient was planned for permanent pacemaker insertion after the surgery.

Aminoacyl-t RNA synthetases（Amino ARSs） are essential enzymes that perform the first step of protein synthesis. Beyond their original roles, Amino ARSs possess non-canonical functions, such as cell cycle regulation and signal transduction. Therefore, Amino ARSs represent a powerful pharmaceutical target if their non-canonical functions can be controlled. Using Amino ARSs-specific primers, we screened m RNA expression in the spinal cord dorsal horn of rats with peripheral nerve injury created by sciatic nerve axotomy. Of 20 Amino ARSs, we found that phenylalanyl-t RNA synthetase beta chain（FARSB）, isoleucyl-t RNA synthetase（IARS） and methionyl-t RNA synthetase（MARS） m RNA expression was increased in spinal dorsal horn neurons on the injured side, but not in glial cells. These findings suggest the possibility that FARSB, IARS and MARS, as a neurotransmitter, may transfer abnormal sensory signals after peripheral nerve damage and become a new target for drug treatment.

Gastrectomy is the main treatment option for gastric cancer patients. Laparoscopic approach has become popular as an alternative to open method during the last decades, and clinical trials have revealed safety and feasibility in the short-and long-term outcomes of laparoscopic gastrectomy. The aim of this review is to summarize the results of prospective clinical trials and propose future perspectives for laparoscopic gastrectomy.

Two popular traditional join algorithms and their parallel versions are introduced. When designing join algorithms in serial computing environment, decomposing inner relation is considered as the right direction to save disk I/Os. However, two different decomposition algorithms are compared, such as inner vs. outer decomposition first algorithms for tuple-based and block-based nested loop joins, showing that the proposed approach is 20% better than general approach. Also lemmas are proved, when we have to use the outer decomposition first parallel join algorithms.
