1.Analysis of the effect of pcDNA3.1 on house keeping gene expression
Journal of Chongqing Medical University 2003;0(06):-
Objective:To investigate the effect of pcDNA3.1 vector on house keeping gene expression and set guide to further study work in using pcDNA3.1. Methods:5 cell lines were transfected with pcDNA3.1,48 h post transfection total RNA was extracted and applied for real time PCR to detect the RNA level of GAPDH、 ?-actin、18sRNA difference.Meanwhile,extract total protein and analyze the GAPDH and?-actin expression by Western blot.Results:RNA and protein levels all show of a decrease in 5 cell lines after transfection,with the most obviously ?-actin.Conclusion:pcDNA3.1 might have non specifinhibition effect to cell,when using pcDNA3. 1 for gene function research,it is not recommend to use ?- actin as reference gene.
3.Protection on intestinal mucosa barrier during perioperative period of esophageal cancer.
Chinese Journal of Gastrointestinal Surgery 2011;14(9):671-673
Intestinal mucosa plays important roles in digestion, absorption and substance exchange between organism and external environment. Meanwhile, it is the largest immune organ and mucosal barrier, including mechanical, biological and immune barrier. A variety of diseases, especially postoperative complications, are associated with the damage of mucosal barrier. Esophageal cancer surgery is complex and many perioperative factors, especially hypoperfusion and fasting, may affect the integrity of intestinal barrier. Understanding of the mechanism of intestinal barrier (mechanical, biological and immune barrier), the physiological function of probiotics, and the benefit of early enteral nutrition to intestinal barrier are important components to achieve fast recovery after surgery for esophageal cancer.

4.Mechanisms of perihematoma tissue injury after intracerebral hemorrhage
International Journal of Cerebrovascular Diseases 2009;17(2):110-114
The morbidity and mortality of intracerebral hemorrhage (ICH) are very high. Brain injury involves in several mechanisms after ICH, including the direct tissue destruction by the mechanical force on brain tissue surrounding the hernatoma in the process of hematoma formation, the release of clot-derived factors (thrombin, hemoglobin degradation products), inflammatory response and complement cascade reaction, etc. This article reviews the above mechanisms
5.Risk factors for airway management after tracheal extubation in old patients
Chinese Journal of Primary Medicine and Pharmacy 2011;18(18):2469-2470
ObjectiveTo investigate the risk factors for airway management after tracheal extubation in old patients. Methods280 patients underwent general anesthesia were enrolled in the study. The procedure of anesthesia induction and maintenance were in the routine method. The patients were with tracheal extubation under clinical standards after operation. Dyspnea was recorded after tracheal extubation. They were divided into dyspnea group and general group. Twelve perioperative variables, ten variables in operation and six post-operative variables of two groups were compared respectively. ResultsThe incidence of dyspnea after tracheal extubation was 8.6%. Analysis identified that obesity( BMI ≥25kg/m2 ), preoperative lung disease and without postoperative neostigmine were the significant risk factors for dyspnea. ConclusionBMI≥25kg/m2 ,preoperative lung disease and without antagonist muscular relaxant were the main risk factors for dyspnea after tracheal extubation in old patients.
6.Perioperative Stroke
International Journal of Cerebrovascular Diseases 2008;16(5):347-352
Strokc is one of the most feared perioperative complications.This article systematically reviews the incidence, mechanisms, risk factors stratification,and relief of perioperative stroke.Aiming at the risk factors and pathogeneses,it is hopeful to improve from the aspect of operative methods.techniques,and medication,and thus to decrease the risks of perioperative stroke and improve prognosis.
