Circulating methylated Septin 9 and ring finger protein 180 for noninvasive diagnosis of early gastric cancer.

Background: Gastric cancer (GC) has a poor prognosis due to patients often being diagnosed at an advanced stage, when metastasis has already occurred. To improve the 5-year survival rate and reduce the number of cancer-related deaths in patients with GC, noninvasive methods for early detection need to be developed. This study aimed to evaluate the value of circulating methylated Septin 9 () and ring finger protein 180 () for the early diagnosis of GC.

Effectiveness of fibrin sealant as hemostatic technique in accelerating ESD-induced ulcer healing: a retrospective study.

Objectives: Healing of gastric endoscopic submucosal dissection (ESD)-induced ulcer is critical for patient recovery. During ESD treatment, submucosal incisions are made with an electrosurgical knife to accomplish en bloc resections of superficial lesions. Nevertheless, excess electrocoagulation may decrease the blood supply of ESD-induced ulcer and delay the ulcer healing.

[Comparison of two gastric cancer screening schemes in a high-risk population].

Objective: To evaluate the effects of two gastric cancer screening schemes for early detection of gastric cancer in a high-risk population.

Methods: A cluster random sampling method was used to select local residents aged 40-69 years from Linqu County, Shandong Province. "Serum pepsinogen initial screening combined with further endoscopic examination (PG scheme)" and "direct endoscopic examination (endoscopy scheme)" were conducted.

[Comparison study of endobronchial ultrasound-guided transbronchial needle aspiration and transbronchial needle aspiration for the diagnosis of hilar and mediastinal lesions].

Objective: To compare the values of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) and TBNA for the diagnosis of hilar and mediastinal lesions.

Methods: The clinical data of 100 patients who underwent EBUS-TBNA (n=50) and TBNA (n=50) between January 2010 and May 2011 were retrospectively reviewed, and the results and complications were recorded.

Results: A total of 121 lesions in the 100 patients were evaluated, the sample yeilds of EBUS-TBNA and TBNA were 90.

Adrenomedullin ameliorates the development of atherosclerosis in apoE-/- mice.

Adrenomedullin (ADM) is a multifunctional peptide regulating cardiovascular homeostasis. We studied the role of ADM in the pathogenesis of atherosclerosis by investigating changes in ADM and its receptors - calcitonin receptor-like receptor (CRLR) and receptor activity-modifying proteins (RAMPs) - in aorta of apoE-/- mice and the effect of exogenous ADM administration. ApoE-/- mice were fed an atherogenic diet for 4 weeks, and apoE-/-+ADM mice were additionally given subcutaneous injections of ADM, 300ng/kg/h, for 4 weeks.

The myocardial response to adrenomedullin involves increased cAMP generation as well as augmented Akt phosphorylation.

In this work we aimed to observe (1) the changes in adrenomedullin (AM) and its receptor system - calcitonin receptor-like receptor (CRLR) and receptor activity modifying proteins (RAMPs) - in myocardial ischemic injury and (2) the response of injuried myocardia to AM and the phosphorylation of Akt to illustrate the protective mechanism of AM in ischemic myocardia. Male SD rats were subcutaneously injected with isoproterenol (ISO) to induce myocardial ischemia. The mRNA levels of AM, CRLR, RAMP1, RAMP2 and RAMP3 were determined by RT-PCR.
