Long-term exposure to air pollutants and new-onset migraine: A large prospective cohort study.

Backgrounds: Short-term exposure to air pollutants increases the risk of migraine, but the long-term impacts of exposure to multiple pollutants on migraine have not been established. The aim of this large prospective cohort study was to explore these links.

Methods: A total of 458,664 participants who were free of migraine at baseline from the UK Biobank were studied.

Manifestation of acute peritonitis and pneumonedema in scrub typhus without eschar: A case report.

Background: Scrub typhus is an acute infectious disease caused by rickettsia infection. The diagnosis is based on eschar, and clinical manifestations can range from asymptomatic to multiorgan dysfunction.

Case Summary: We report the case of a 35-year-old man living in Zhuhai, Guangdong, China, who had repeated high fever with a maximum body temperature of 40.

Chlorin e6-loaded sonosensitive magnetic nanoliposomes conjugated with the magnetic field for enhancing anti-tumor effect of sonodynamic therapy.

In sonodynamic therapy (SDT), when Chlorin e6 (Ce6) accumulates in tumor tissues, its anti-tumor effect can be achieved by ultrasound activation. To increase the local drug concentration of Ce6 in tumor cells, we had established a novel drug delivery system, Ce6-loaded sonosensitive magnetic nanoliposome (Ce6/SML), which realized the targeting delivery by the external magnetic field. It was worth mentioning that the targeting release of Ce6/SML and the activation on Ce6 could be achieved simultaneously by ultrasound of SDT.

Combined PET/CT with thoracic contrast-enhanced CT in assessment of primary cardiac tumors in adult patients.

Background: F-FDG PET/CT is a key molecular imaging modality to noninvasively assess and differentiate benign and malignant cardiac tumors. However, few benign cardiac tumors can be characterized by increased F-FDG uptake, which makes differential diagnosis difficult. This study sought to retrospectively evaluate whether combined F-FDG PET/CT with thoracic contrast-enhanced CT (CECT) helps in assessing primary cardiac tumors in adult patients, compared with CECT or PET/CT alone.

Concomitant coronary and renal revascularization improves left ventricular hypertrophy more than coronary stenting alone in patients with ischemic heart and renal disease.

Percutaneous transluminal renal artery stenting (PTRAS) has been proved to have no more benefit than medication alone in treating atherosclerotic renal artery stenosis (ARAS). Whether PTRAS could improve left ventricular hypertrophy (LVH) and reduce adverse events when based on percutaneous coronary intervention (PCI) for patients with coronary artery disease (CAD) and ARAS is still unclear. A retrospective study was conducted, which explored the effect of concomitant PCI and PTRAS versus PCI alone for patients with CAD and ARAS complicated by heart failure with preserved ejection fraction (HFpEF).

Medial Compartment Decompression by Fibular Osteotomy to Treat Medial Compartment Knee Osteoarthritis: A Pilot Study.

Compared with high tibial osteotomy and total knee arthroplasty, the authors found a simpler surgical procedure, partial fibular osteotomy, could effectively relieve knee pain and also correct the varus deformity for patients with medial compartment knee osteoarthritis (OA). From January 1996 to April 2012, a total of 156 patients with medial compartment OA were treated by proximal fibular osteotomy in the authors' hospital. A 2-cm-long section of fibula was resected 6 to 10 cm below the fibular head.

Decrease of glomerular filtration rate may be attributed to the microcirculation damage in renal artery stenosis.

Background: The decrease of glomerular filtration rate has been theoretically supposed to be the result of low perfusion in renal artery stenosis (RAS). But the gap between artery stenosis and the glomerular filtration ability is still unclear.

Methods: Patients with selective renal artery angiogram were divided by the degree of renal artery narrowing, level of estimated glomerular filtration rate (eGFR), respectively.

[Value of preventive tracheotomy in patients with acute cervical spinal cord injury].

Objective: To evaluate the value of preventive tracheotomy in patients with acute cervical spinal cord injury.

Methods: A retrospective analysis was performed on 54 cases of severe C4-C8 cervical spinal cord injury patients undergoing anterior fixation. They were classified as A and B according to the criteria of American Spinal Injury Association.

[Analysis of coronary rotational atherectomy related complications].

Objective: To analysis the complications of coronary rotational atherectomy and evaluate the safety of this procedure.

Method: A total of 250 rotational atherectomy cases from April 1994 to February 2012 were screened retrospectively and 22 cases patients (8.8%) with rotational atherectomy-related complications were included in this analysis.

Perioperative aortic dissection rupture after endovascular stent graft placement for treatment of type B dissection.

Background: The perioperative aortic dissection (AD) rupture is a severe event after endovascular stent graft placement for treatment of type B AD. However, this life-threatening complication has not undergone systematic investigation. The aim of the study is to discuss the reasons of AD rupture after the procedure.

Application of triangular vector to functionally reconstruct the medial collateral ligament with double-bundle allograft technique.

Purpose: The purpose of this study was to present a novel medial collateral ligament (MCL) reconstruction technique and investigate the clinical outcomes of this surgical procedure.

Methods: From July 2006 to June 2009, 56 patients with medial instability of the knee were treated with MCL reconstruction and followed up for 33 months on average. These patients were divided into 2 groups based on whether anterior cruciate ligament (ACL) injury was present: 27 patients had isolated MCL injury, whereas 29 patients had combined MCL-ACL injury.

Effect of atorvastatin therapy on borderline vulnerable lesions in patients with acute coronary syndrome.

Introduction: It is still controversial whether borderline lesions with a vulnerable plaque should be stented early or simply treated pharmacologically. No data exist concerning the potential effects of statin therapy on borderline vulnerable lesions in patients with acute coronary syndrome (ACS).

Material And Methods: Fifty patients with ACS whose culprit lesions were classified as "borderline lesions" were enrolled.

[Vulnerable plaque burden post pharmacological and interventional treatments in patients with acute coronary syndrome and borderline lesion: intravascular ultrasound follow up results].

Objective: To compare the efficacy and safety between the interventional and conservative treatment options for borderline vulnerable plaque lesion in acute coronary syndrome (ACS) patients by intravascular ultrasound (IVUS).

Methods: A total of 100 ACS patients [78 male, age 43 - 74 (60.4 ± 14.

[Intravascular ultrasound-guided interventional therapy for borderline lesions in patients with acute coronary syndrome].

Objective: To assess the efficacy and safety of intravascular ultrasound (IVUS)-guided interventional therapy for borderline lesions in patients with acute coronary syndrome (ASC).

Methods: Thirty-one ASC patients with borderline lesions (coronary artery stenosis between 40%-70% confirmed by coronary arteriography [CAG]) and a minimal lumen area (MLA) of the infarction related artery(IRA) < or =4.0 mm(2) shown by IVUS underwent percutaneous coronary intervention (PCI).

Poly[diaqua-μ-oxalato-μ-pyrazine-2-carbox-yl-ato-lanthanum(III)].

In the title complex, [La(C(5)H(3)N(2)O(2))(C(2)O(4))(H(2)O)(2)](n), the La(III) ion is coordinated by one N and three O atoms from two pyrazine-2-carboxylate ligands, by four O atoms from two oxalate ligands and by two O atoms of two water molecules, displaying a distorted bicapped square-anti-prismatic geometry. The carboxyl-ate groups of pyrazine-2-carboxyl-ate and oxalate ligands link the lanthanum metal centres, forming layers parallel to (10). The layers are further connected by inter-molecular O-H⋯O and N-H⋯O hydrogen-bonding inter-actions, forming a three-dimensional supra-molecular network.
