Academic Journal of Second Military Medical University 1981;0(04):-
An experimental model of isolated rabbit working hearts was used to investigate whether supplementing cardioplegic solution with oxygen free radical scavengers exerts protective effect on ischemic and reperfusad heart.Animal hearts wero randomly divided into two groups : simple cardioplegic solution was used in the control group ; cardioplegic solution was supplemented with superoxide dismutase plus catalase in the experimental group.Following 120 min of ischemic arrest and 30 min of reperfusion, recoveries of LVPSP, LVEDP, LV + dp/dt max and LV-dp/dt max, expressed as percentage of preischemic control valu-S, and tissue ATP contjnt w-r significantly better (P
2.Chest wall resection and reconstruction:an update
Academic Journal of Second Military Medical University 2000;0(08):-
Chest wall resection and reconstruction remains a severe challenge for reconstructive surgeons,which often leads to conservative treatment regimens in clinical practice,consequently resulting in poor outcomes(high morbidity and mortality).In recent 20 years,advances in muscle flap surgery and availability of chest reconstructive prosthesis have encouraged the surgeons to take an active attitude toward chest wall resection;many "unresectable" lesions now have a chance to be resected and cured.This article reviews the problems concerning the principles for chest wall resection,reconstruction,prosthesis selection,etc.in chest wall reconstruction.
3.Endoscope in radical operation for esophageal cancer:current status
Academic Journal of Second Military Medical University 2001;0(09):-
Traditional operation for esophageal cancer includes esophagectomy and digestive tract reconstruction,which is associated with more postoperative complications and high mortalities due to severe trauma.Endoscopic surgery(including thoracoscope,mediastinoscope,and laparoscope) for radical resection of esophageal cancer has mild operative trauma,less bleeding and mild postoperative pain,resulting in less postoperative complications and low mortalities.This article analyzes the current status of endoscopic surgery in radical operation of esophageal cancer and the existing problems,providing reference for the development of minimally invasive surgery of esophageal cancer.
4.Role of FOXP3 in tumor immunity
Academic Journal of Second Military Medical University 2001;0(09):-
FOXP3,a member of the forkhead/winged-helix family,exerts its immunosupression effect by regulating the development,differentiation and maturation of CD4+ CD25+ regulatory T cells(Treg).Treg plays an important role in immune escape mechanism in oncology research.This article reviews the expression of FOXP3 in various types of tumors and its role in tumor immunology and immunotherapy.
5.Neurotoxicity of intrathecal doxepin in rats
Chinese Journal of Anesthesiology 2012;32(3):311-313
Objective To investigate the neurotoxicity of intrathecal (IT) doxepin in rats.Methods Twenty-four adult male Wistar rats weighing 250-300 g in which intrathecal micro-catheter was successfully implanted without complications were randomly divided into 4 groups ( n =6 each):control group ( group N ) and 3 doxepin groups receiving IT doxepin 40,20 and 10 mmol/L 0.2 μl/g respectively (groups D40,D20,D10 ).In N group normal saline was injected IT instead of doxepin.The animals were killed at 6 h after IT administration.The lumbar segment of the spinal cord was removed for microscopic examination and determination of myelin basic protein (MBP) content in the spinal cord using a double-antibody sandwich (ELISA).Results The severity of neuronal damage and decrease in MBP content in the spinal cord induced by IT doxepin were dose-dependent.Conclusion The neurotoxicity induced by IT doxepin is dose-dependent.
6.The expression of Fas ligand in esophageal carcinoma and its clinic significance.
Chinese Journal of Thoracic and Cardiovascular Surgery 2001;17(2):87-89
Objective: To determine the expression of Fas ligand (FasL) in the patients with esophageal carcinoma and its clinic significance. Methods: The expression of FasL was measured by immunohistochemical technique in 30 patients with esophageal cancer. The numbers of tumor infiltrationg (TIL) were accounted by immunohistochemically stained CD45. Results: 76.6% of specimen expressed FasL. The difference of FasL expression was significant between each TNM stage. There was a negative correlation between the number of TIL and the expression of FasL. Conclusion: The expression of FasL in esophageal carcinoma may correlate with its invasion and metastasis.
7.Current advance of non-invasive positive-pressure ventilation treating upper airway obstructive diseases in children
Chinese Journal of Applied Clinical Pediatrics 2014;29(16):1258-1260
The non-invasive positive-pressure ventilation(NPPV) play an important role in treating patient with upper airway obstructive diseases.The use of NPPV in children has significantly increased in recent years internationally.Nevertheless,the paediatric NPPV support in China was less reported.This review aimed to clarify the indications,efficacy and technical methods in NPPV,and therefore searched papers including clinical studies,reviews and guidelines focusing on children with upper airway obstructive diseases who were treated on NPPV.The review concluded that NPPV is a treatment choice for patient who has upper airway obstruction and can not be solved by surgery.The NPPV avoids the impairment to the body caused by recurrent hypoxemia and arousals,decreases the rate of intubation and improves the quality of life.NPPV need to be preformed in a professional children's medical center.Education and training for the parent is the key point of improving treatment compliance.
8.Application of high flow nasal cannula oxygen in pediatrics
Chinese Journal of Applied Clinical Pediatrics 2021;36(9):708-711
Respiratory support is the treatment of respiratory diseases.Currently, the commonly used methods of respiratory support include nasal catheter oxygen or mask oxygen, noninvasive and invasive ventilation, etc.High flow nasal cannula oxygen (HFNC) is a new kind of therapy, which was commonly used in preterm infants as the instead of continuous positive airway pressure (CPAP). However, in recent years, HFNC is more commonly used in children′s intensive care unit and general wards.In this paper, the efficacy and safety of HFNC in pediatric are reviewed.

To explore the causes and treatment of arrhythmia during the peri-operative period of thoracic surgery, 566 patients undergoing pulmonary surgery were included for a retrospective analysis. Among them, 121 patients were complicated by arrhythmia. With timely treatment, the arrhythmia was controlled in all patients. The causes of arrhythmia after pulmonary surgery were old age, heart and lung diseases, abnormal ECG before operation, and long operation time.

Objective To summarize and discuss the therapeutic strategies of mechanical ventilation for severe thoracic trauma complicated by acute respiratory distress syndrome (ARDS). Methods Ninely-four patients with severe thoracic trauma complicated by ARDS, in whom mechanical ventilation were instituted and multiple methods in addition to routine treatment, were analysed. Results Eight of them died, with a total mortality of 8.5%. After Jan. 1995, by using small tidal volume mechanical ventilation, the use of mechanical ventilation was maintained for 6.8?2.2 days(P
