[Protective effects of perfluorocarbon combined with ligustrazine against lung ischemia-reperfusion injury in rats].

Objective: To investigate the effects of perfluorocarbon and ligustrazine in protecting the lungs against ischemia-reperfusion injury in rats.

Methds: Forty SD rats with ischemia-reperfusion lung injury were randomized equally into control, ligustrazine, perfluorocarbon, and perfluorocarbon plus ligustrazine groups and received the corresponding treatment via the tail vein 5 min before reperfusion. The lung tissues were harvested and the levels of malondialdehyde (MDA), myeloperoxidase (MPO), superoxide dismutase (SOD) and tumor necrosis factor-α (TNF-α) were detected 3 h after reperfusion.

Tuning inter-dot tunnel coupling of an etched graphene double quantum dot by adjacent metal gates.

Graphene double quantum dots (DQDs) open to use charge or spin degrees of freedom for storing and manipulating quantum information in this new electronic material. However, impurities and edge disorders in etched graphene nano-structures hinder the ability to control the inter-dot tunnel coupling, tC, the most important property of the artificial molecule. Here we report measurements of tC in an all-metal-side-gated graphene DQD.

[Study on the distribution of Chinese medical constitutions of hypertension complicated diabetes patients].

Objective: To investigate the distribution features of Chinese medical constitutions in hypertension complicated diabetes patients.

Methods: Recruited were 251 primary hypertension inpatients at the Department of Neurology and the Department of Cardiology, Mindong Hospital of Ningde City from October 2010 to March 2011. They were assigned to two groups according to whether they were complicated with diabetes, i.

[Preparation and clinical application of an intelligent determination and analysis system for glomerular filtration rate].

Objective: To prepare an intelligent determination and analysis system for renal glomerular filtration rate(GFRBMAS), and to explore its value in clinical setting.

Methods: GFRBMAS was prepared by programming with VB 6.0 software.

[Correlative study between angiotensin-converting enzyme gene polymorphism and hepatorenal syndrome].

Objective: To investigate the relationship between insertion/deletion (I/D) polymorphism of angiotensin-converting enzyme (ACE) gene and uncompensated cirrhosis of liver with hepatorenal syndrome (HRS).

Methods: ACE I/D polymorphism was detected by polymerase chain reaction amplification of DNA fragment in 56 patients of uncompensated liver cirrhosis with HRS, and 60 healthy individuals served as the controls. At the same time, alanine aminotransferase, aspartate transaminase, serum creatinine (SCr), blood urea nitrogen (BUN) and glomerular filtration rate (GFR) etc.
