Asymptomatic Pulmonary Embolism After Shoulder Arthroscopy: Case Report and Literature Review.

Background: Pulmonary embolism (PE) is extremely rare after shoulder arthroscopy. However, early identification of the situation deserves attention due to its potential risk of causing death. By now, it is still difficult to detect the PE without symptoms and clear sources during the perioperative period.

"Median paralyzing dose" and "multiple regression analysis", a new viewpoint to the research method of spinal cord injury.

Introduction: Spinal cord impact is a mature method for building models of spinal cord injury (SCI). However, a common problem is that the degree of elicited paralysis may not be identical even though animals receive the same impact. We hypothesize that this difference may be caused by the difference in the secondary injury mechanism of SCI and there might be an impact dosage named "median paralyzing dose (PD)", similar as the "median lethal dose (LD)" in pharmacology.

Safe range of shortening the middle thoracic spine, an experimental study in canine.

Purpose: To determine the safe range of shortening the spinal column at middle thoracic spine and to observe the changes in blood-spinal cord barrier (BSCB), microglia/macrophage activation and inducible nitric oxide synthase (iNOS) activity after shortening-induced spinal cord injury.

Methods: Dogs were allocated to four groups. Group A (control) underwent laminectomy of T7 without shortening the spinal column.

Treatment of inadvertent subclavian artery cannulation with a percutaneous vascular closure device.

Inadvertent puncture of the subclavian artery is an uncommon but potentially fatal complication of the commonly performed internal jugular vein catheterization. We report a case of accidental subclavian artery catheterization close to the vertebral artery during internal jugular venous cannulation, which was successfully managed in the interventional suite with catheter removal and use of a vascular closure device.

Magnetic compression technique for colonic anastomosis in rats.

Background: Magnetic compression technique (MCT) is useful for construction of digestive tract anastomoses in pigs and dogs. This study determined the efficacy of MCT for performing colonic anastomosis in rats.

Methods: Twenty male Sprague-Dawley rats (230-280 g) were randomly apportioned to a study group that underwent colonic anastomosis with MCT or a control group subjected to hand-sewn colonic anastomosis.

Magnetic Anastomosis Rings to Create Portacaval Shunt in a Canine Model of Portal Hypertension.

Purpose: This study evaluated a novel magnetic compression technique (magnamosis) for creating a portacaval shunt in a canine model of portal hypertension, relative to traditional manual suture.

Methods: Portal hypertension was induced in 18 dogs by partial ligation of the portal vein (baseline). Six weeks later, extrahepatic portacaval shunt implantation was performed with either magnetic anastomosis rings, or traditional manual suture (n = 9, each).

A novel magnetic compression technique for small intestinal end-to-side anastomosis in rats.

Background: Magnetic compression technology is a safe and convenient digestive tract reconstruction technique in large animals. The purpose of this study was to verify the feasibility of using the micromagnetic ring for construction of small intestinal end-to-side anastomosis in rats.

Methods: Thirty male Sprague-Dawley albino rats were randomly divided into two groups: a study group that underwent small intestinal anastomosis with micromagnetic ring and a control group that had hand-sewn anastomosis.

Carbon Monoxide-Releasing Molecule-2 Inhibits Connexin 43-Hemichannel Activity in Spinal Cord Astrocytes to Attenuate Neuropathic Pain.

Carbon monoxide-releasing molecule (CORM-2) acts as a carbon monoxide (CO) deliverer in a more controlled manner without altering carboxyhemoglobin level and exerts potential function in inhibiting inflammation and/or acute nociception. However, the regulatory mechanism of CORM-2 on spinal nerve ligation (SNL)-induced neuropathic pain is not currently clear. Our study aims to investigate the role of CORM-2 in neuropathic pain and the underlying mechanism.

Effects of the Zhikang capsule on healing of the flap after radical breast cancer surgery.

This study aimed to investigate the effect and mechanism of trauma flap healing promoted by the Zhikang capsule after radical breast cancer surgery. The enrolled breast cancer patients were randomly divided into two groups: treatment and observation. The patients in the treatment group were treated with the Zhikang capsule in addition to the conventional dressing changes, while patients in the observation group underwent only the regular dressing changes.
