[Rapid identification of the different constituents in Fructus Schisandrae Chinensis before and after processing by UHPLC-QTOF/MS~E combining with metabonomics].

This study was performed to use UHPLC-QTOF/MSE technology to rapidly search and identify variations of chemical ingredients between Fructus Schisandrae Chinensis and its processed products. The present study provides a basis for the study of Chinese herbal medicine processing with a focus on the impact of processing on chemical components. Using a time-dependent data scan mode (MSE) couple with metabolomics technology, we acquired accurate data and identified the potential chemical markers.

Evaluation of MDCK cell-derived influenza H7N9 vaccine candidates in ferrets.

Avian-origin influenza A (H7N9) viruses emerged as human pathogens in China in early 2013 and have killed >100 persons. Influenza vaccines are mainly manufactured using egg-based technology which could not meet the surging demand during influenza pandemics. In this study, we evaluated cell-based influenza H7N9 vaccines in ferrets.

Clinico-pathological features and prognosis of invasive micropapillary carcinoma compared to invasive ductal carcinoma: a population-based study from China.

Background: Invasive micropapillary carcinoma (IMPC) of the breast is a rare subtype of breast cancer that is associated with a high incidence of regional lymph node metastases and a poor clinical outcome. However, the clinico-pathological features and prognostic factors of IMPC are not well understood.

Patients And Methods: A total of 188 IMPC cases and 1,289 invasive ductal carcinoma (IDC) cases were included.

Rosiglitazone protects against palmitate-induced pancreatic beta-cell death by activation of autophagy via 5'-AMP-activated protein kinase modulation.

Promoting beta-cell survival is crucial for the prevention of beta-cell failure in diabetes. Thiazolidinediones, a widely used drug to improve insulin sensitivity in clinical practice, is found to have a protective effect on islet beta-cell. To date, the mechanism underlying the protective role of thiazolidinedione on beta-cell survival remain largely unknown.

[Separation of PM2.5 from coal combustion with phase change].

The influence of two methods of gas moisture conditioning on removal efficiency of PM2.5 from coal combustion with addition of atomized droplets and steam was investigated. The particles size distribution and number concentration were measured in real time by electrical low pressure impactor (ELPI).
