The timing of the initial collision between the South and North China blocks constraining from the sediments in the eastern Sichuan Basin.

In this study, detrital zircon U-Pb geochronology, trace element and Hf isotopic compositional data from the Early-Middle Triassic clastic rocks in the eastern Sichuan Basin were obtained to distinguish the sediment provenance and constrain the timing of the initial collision between the South China and North China blocks. Detrital zircons from the Early Triassic Feixianguan Formation clastic rocks yield one major age peak at 2476 Ma and three minor age peaks at 1886, 802 and 304 Ma. These detrital zircons may be derived from the South China Block.

The Use of Mobile Health Applications to Improve Patient Experience: Cross-Sectional Study in Chinese Public Hospitals.

Background: The proliferation of mobile health apps has greatly changed the way society accesses the health care industry. However, despite the widespread use of mobile health apps by patients in China, there has been little research that evaluates the effect of mobile health apps on patient experience during hospital visits.

Objective: The purpose of our study was to examine whether the use of mobile health apps improves patient experience and to find out the difference in patient experience between users and nonusers and the characteristics associated with the users of these apps.

The Outpatient Experience Questionnaire of comprehensive public hospital in China: development, validity and reliability.

Objective: The objective of this study is to describe the development of the Outpatient Experience Questionnaire (OPEQ) and to assess the validity and reliability of the scale.

Design: Literature review, patient interviews, Delphi method and Cross-sectional validation survey.

Setting: Six comprehensive public hospitals in China.

Hypothesizing that histone deacetylase inhibitors can be used to reverse multiple drug resistance.

It is well known that the mechanism of action of chemotherapeutic drugs and their ability to induce multidrug resistance (MDR) are of relevance to cancer treatment. Although MDR is a multifactorial process, the main obstacle is the expression of multidrug-efflux pumps that lowers the intracellular drug levels. P-glycoprotein (P-gp) is the longest identified efflux pump.

Correlation between MDR1 methylation status in the promoter region and MDR1 genetic polymorphism in 194 healthy Chinese Han subjects.

Aims: To investigate the correlation between the methylation status in the MDR1 promoter region and the MDR1 genetic polymorphism.

Methods: A total of 194 unrelated subjects (105 men and 89 women) with a median age of 26 years were enrolled in this study. DNA was extracted and PCR-RFLP was performed for C1236T, C3435T and G2677T/A polymorphism genotyping.

Influence of osmotic distillation on membrane absorption for the treatment of high strength ammonia wastewater.

Osmotic distillation (OD) was found to be a coupled process in membrane absorption (MA) for the treatment of high strength ammonia wastewater. As a result, ammonia could not be concentrated in absorption solution(AS) as expected. The inhibition of the coupled OD in MA process was investigated as well as various factors affecting the inhibition.
