A duplex nested RT-PCR method for monitoring porcine epidemic diarrhea virus and porcine delta-coronavirus.

Background: Porcine epidemic diarrhea virus (PEDV) and porcine delta-coronavirus (PDCoV) are economically important pathogens that cause diarrhea in sows and acute death of newborn piglets. Moreover, the emerging PDCoV was reported to infect children. The current situation is that vaccine prevention has not met expectations, and emergency containment strategies following outbreaks cannot prevent the damages and losses already incurred.

The Efficacy of a Comprehensive Reminder System to Improve Health Behaviors and Blood Pressure Control in Hypertensive Ischemic Stroke Patients: A Randomized Controlled Trial.

Background And Objective: The health behaviors of hypertensive stroke patients in China are not satisfactory. In this study, we tested the effect of a Health Belief Model Comprehensive Reminder System on health behaviors and blood pressure control in hypertensive ischemic stroke patients after occurrence and hospital discharge.

Methods: A randomized, parallel-group, assessor-blinded experimental design yielded participation of 174 hospitalized hypertensive ischemic stroke patients.

[Decitabine Enhances the Sensitivity of Leukemia Stem Cell to Allo-NK Cell-Mediated Killing].

Objective: To investigate the allo-NK cell-mediated killing effect enhanced by decitabine on leukemia stem cells(LSC) and the underlying mechanisms.

Methods: LSC were separated from KG1a cells by using immunomagnetic beads. Allo-NK cells were isolated and purified from PBMC of healthy donors.

The effectiveness of a comprehensive reminder system in the secondary prevention of hypertensive ischaemic stroke: randomized controlled trial protocol.

Aim: The aim of this study was to determine whether the Comprehensive Reminder System based on the Health Belief Model improves health belief, health behaviours, medication adherence and blood pressure control as a means of decreasing the rate of stroke recurrence among hypertensive ischaemic stroke.

Background: Hypertensive patients having experienced recent ischaemic strokes are at high risk for stroke recurrence. Several trials attempted to improve secondary stroke prevention via patient education, however, patient outcomes remained poor.

Effectiveness of Goal-Setting Telephone Follow-Up on Health Behaviors of Patients with Ischemic Stroke: A Randomized Controlled Trial.

Background: Adopting healthy behaviors is critical for secondary stroke prevention, but many patients fail to follow national guidelines regarding diet, exercise, and abstinence from risk factors. Compliance often decreases with time after hospital discharge, yet few studies have examined programs promoting long-term adherence to health behaviors. Goal setting and telephone follow-up have been proven to be effective in other areas of medicine, so this study evaluated the effectiveness of a guideline-based, goal-setting telephone follow-up program for patients with ischemic stroke.

Psychometric Properties of the Kessler 10 Scale in Chinese Parents of Children With Cancer.

Background: The Kessler Psychological Distress Scale (K10) has been widely used in rating psychological distress in general and clinical populations. However, whether it can be used in parents of children with cancer is unknown. Still lacking is the evidence on its reliability and validity in culturally diverse groups.

Role of tumour necrosis factor-a in the regulation of T-type calcium channel current in HL-1 cells.

Increasing evidence indicates that inflammation contributes to the initiation and perpetuation of atrial fibrillation (AF). Although tumour necrosis factor (TNF)-α levels are increased in patients with AF, the role of TNF-α in the pathogenesis of AF remains unclear. Besides L-type Ca(2+) currents (IC a,L ), T-type Ca(2+) currents (IC a,T ) also plays an important role in the pathogenesis of AF.

Left ventricular deformation associated with cardiomyocyte Ca(2+) transients delay in early stage of low-dose of STZ and high-fat diet induced type 2 diabetic rats.

Background: In the early stage of diabetes, the cardiac ejection fraction is preserved, despite the existence of the subclinical cardiac dysfunction to some extent. However, the detailed phenotype of this dysfunction and the underlying mechanism remain unclear. To improve our understanding of this issue, we used low-dose STZ and high-fat diet to induce type 2 diabetic models in rats.

The relationship between hospital work environment and nurse outcomes in Guangdong, China: a nurse questionnaire survey.

Aims And Objectives: This study examines the relationship between hospital work environments and job satisfaction, job-related burnout and intention to leave among nurses in Guangdong province, China.

Background: The nursing shortage is an urgent global problem and also of concern in China. Studies in Western countries have shown that better work environments are associated with higher nurse satisfaction and lower burnout, thereby improving retention and lowering turnover rates.

[The effects of safflower injection on lipid peroxidation level and expression of heme oxygenase-1 of the rat liver with hypoxia and hypercapnia].

Aim: To investigate the changes of lipid peroxidation level and expression of heme oxygenase-1 of the rat liver with chronic hypoxia and hypercapnia, and the effects of Safflower injection (a compond of Chinese Traditional medicine).

Methods: Thirty male SD rats weighing 180 approximately 220 g were divided into three groups (n=10): control group (N group), chronic hypoxia and hypercapnia for four weeks group(F group), and Safflower injection group (H group). SOD and MDA in liver tissue were measured by spectrophotometric method.

[Study on changes of CT performance and pulmonary function in renal transplant recipients with pneumocystis pneumonia].

Objective: To investigate dynamic changes of CT performance and pulmonary function in renal transplant recipients with pneumocystis pneumonia.

Methods: A retrospective analysis was made upon the clinic data of chest CT, arterial blood gas and pulmonary function in renal transplant recipients with pneumocystis pneumonia from 2002 to 2006 in the first affiliated hospital of Wenzhou Medical College.

Results: 16 cases were enrolled, followed by average age (36 +/- 11) years, mean duration after transplantation (4.

[Effect of curcumin on pulmonary hypertension and wall collagen of pulmonary arterioles of chronic hypoxic hypercapnic rats].

Aim: To study the effect of curcumin on pulmonary arterial pressure and type I collagen of pulmonary arterioles in pulmonary hypertensive rats induced by chronic hypoxia and hypercapnia.

Methods: Thirty six rats were randomly divided into three groups: normal control group (NC), hypoxic hypercapnic group (HH) and hypoxic hypercapnia + curcumin group (HC). Collagen I in pulmonary arterioles was observed by the technique of immunohistochemistry.

[Effect of hypoxic hypercapnia on expression of COX-2 mRNA in pulmonary arterioles].

Aim: To study the effect of chronic hypoxic hypercapnia on expression of COX-2 mRNA in pulmonary arterioles.

Methods: SD rats were randomly divided into two groups: control group and hypoxic hypercapnic group. COX-2 mRNA was observed in pulmonary arterioles by the technique of in situ hybridization.
