The preventive effects of different doses of atorvastatin on contrast-induced acute kidney injury after CT perfusion.

Background: Contrast-induced acute kidney injury (CI-AKI) is a severe complication among patients receiving intravascular contrast media. The purpose of this study was to investigate the preventive effects of pretreatment of atorvastatin at intensive doses on CI-AKI after computed tomography (CT) perfusion.

Methods: The levels of serum creatinine (SCR), blood urea nitrogen (BUN), Cystatin C (CysC), estimated glomerular filtration rate (eGFR), high-sensitivity C-reactive protein (hs-CRP), and interleukin-6 (IL-6) in patients were compared between the observation group receiving 40 mg/kg atorvastatin and the control group receiving 20 mg/kg atorvastatin before and 72 h after CT examination.

Anti-Müllerian Hormone Accelerates Pathological Process of Insulin Resistance in Polycystic Ovary Syndrome Patients.

Insulin resistance (IR) is one of the most common features of polycystic ovary syndrome (PCOS), which is related to obesity. Whether increased anti-Müllerian hormone (AMH) levels in PCOS are involved in the pathogenesis of insulin resistance remains unclear. We investigated serum levels of leptin and AMH along with basic clinical and metabolic parameters in 114 PCOS patients and 181 non-PCOS women.

Diagnosis and treatment of pheochromocytoma in urinary bladder.

Objective: To study the diagnosis and treatment of pheochromocytoma in urinary bladder.

Methods: Six cases of bladder pheochromocytoma were studied. Four cases showed hypertension, 3 of which were paroxysmal hypertension during urination.

[Treatment of wide-necked cerebral aneurysms using stent and balloon-assisted technique].

Objective: To discuss the avail of balloon and stent-assisted Guglielmi detachable coil (GDC) placement in treatment of wide-necked cerebral aneurysm.

Methods: Eighty-seven patients with 92 wide-necked aneurysms undergone endovascular procedures using the balloon and stent-assisted remodeling technique. Respectively, appropriate Neuroform stents delivered with a 5 mm landing zone on either side of the aneurysm neck, the microcatheter entered through the interstice, aneurysms were embolized at one or several times.

[3-dimension computed tomography angiography and digital subtraction angiography in diagnosis of intracranial aneurysm: a comparative study].

Objective: To compare the appliance values off 3-dimension computed tomography (CTA) and digital subtraction angiography (DSA) in diagnosis of intracranial aneurysm (ICA).

Methods: Eighty-six with subarachnoid hemorrhage underwent 2-D DSA, and 3-DCTA and 3-D DSA, both including maximum intensity projection (MIP) and multiple planner reconstruction (MPR), volume rending (VR). The accuracy, misdiagnosis rate, and missed diagnosis rate of these 3 techniques were compared.
