| 1 | Oxygenation,inflammatory response and lung injury during one lung ventilation in rabbits using inspired oxygen fraction of 0.6 vs.1.0显示文摘Maintaining adequate oxygenation during one-lung ventilation(OLV) requires high inspired oxygen fraction(FiO_2).However,high FiO_2 also causes inflammatory response and lung injury.Therefore,it remains a great interest to clinicians and scientists to optimize the care of patients undergoing OLV.The aim of this study was to determine and compare oxygenation,inflammatory response and lung injury during OLV in rabbits using FiO_2 of 0.6 vs.1.0.After 30 minutes of two-lung ventilation(TLV) as baseline,30 rabbits were randomly assigned to three groups receiving mechanical ventilation for 3 hours:the sham group,receiving TLV with 0.6 FiO_2;the 1.0 FiO_2 group,receiving OLV with 1.0 FiO_2;the 0.6 FiO_2 group,receiving OLV with 0.6 FiO_2.Pulse oximetry was continuously monitored and arterial blood gas analysis was intermittently conducted.Histopathologic study of lung tissues was performed and inflammatory cytokines and the mRNA and protein of nuclear factor kappa B(NF-κB) p65 were determined.Three of the 10 rabbits in the 0.6 FiO_2 group suffered hypoxemia,defined by pulse oximetric saturation(SpO_2) less than 90%.Partial pressure of oxygen(PaO_2),acute lung injury(ALI) score,myeloperoxidase(MPO),tumor necrosis factor-a(TNF-α),interleukin-6(IL-6),mRNA and protein of NF-kB p65 were lower in the 0.6 FiO_2group than in the 1.0 FiO_2 group.In conclusion,during OLV,if FiO_2 of 0.6 can be tolerated,lung injury associated with high FiO_2 can be minimized.Further study is needed to validate this finding in human subjects. | Zeping Xu Lianbing Gu Qingming Bian Pengyi Li Lijun Wang Jingyuan Zhang Yanning Qian | 2017 | The Journal of Biomedical Research2017，31，1： | 7 |

| 3 | 支气管阻塞器用于胸腔镜下肺癌术患者单肺通气的效果(英文)显示文摘Objective:The aim of this study was to observe the effect of endobronchial blocker tube in the pulmonary carcinoma with video-assisted thoracic surgery.Methods:Forty patients of pulmonary carcinoma with video-assisted thoracic surgery were randomly assigned into two groups with twenty cases each:endobronchial blocker tube group(group 1) and double-lumen endobronchial tube group(group 2).After anesthesia was induced,in group 1,single lumen tube was intubated at first,and then endobronchial blocker tube intubated to left or right primary bronchus under the guidance of fiber-optic bronchoscope according to operational necessary,injected 2-4 mL air to blocker balloon and blocker one lateral primary bronchus for one-lung ventilation necessarily;while in group 2,the position of double-lumen endobronchial tube was confirmed with fiber-optic bronchoscope after intubation.Blood samples were collected before anesthesia induction,double lumen ventilation,at the one-lung ventilation of 5 min,30 min,60 min,120 min and 180 min,SBP,DBP,HR,SpO2,partial pressure of end tidal carbon dioxide(PetCO2),pH,PaO2,PaCO2,PaO2/FiO2 were recorded.Results:Forty cases' intubations were all successful.There were no differences in SBP,DBP,HR,SpO2,PetCO2,pH,PaCO2 between two groups in different points(P > 0.05).Paw in group 1 was lower than group 2,PaO2 and PaO2/FiO2 in group 1 was higher than group 2 in the one lung ventilation of 5 min,30 min,60 min,120 min and 180 min.Conclusion:The endobronchial blocker tube can meet the request of video-assisted thoracic surgery,with the special advantages of simple insertion,lower airway and better oxygenation.Endobronchial blocker tube offer a new way for one-lung ventilation in the pulmonary carcinoma with video-assisted thoracic surgery. | Lairong Sun Lianbing Gu Bihui Ren Ninglei Qju Lijun Wang | 2011 | The Chinese-German Journal of Clinical Oncology2011，10，4： | 1 |
| 4 | 老年食管癌患者围术期T淋巴细胞亚群的变化(英文)显示文摘Objective:The aim of the study was to observe and compare the trend of T-lymphocyte subsets in the elder and adult esophageal carcinoma patients postoperatively. Methods: Forty-four esophageal carcinoma patients, classified as ASA physical status I-II, were divided into two groups. Twenty-two patients aged than 65 years were grouped as elder patient group, and the rest twenty-two patients, served as adult patient group, were younger than 60 years old. The jugular venous blood samples were collected before induction of anesthesia (T1) as baseline, after completion of surgery (T2), on the first, second and fifth postoperative days (T3, T4 and T5), respectively. The blood counts of CD3+, CD4+ and CD8+T-lymphocyte were measured by flow cytometer. Results: Compared with the baseline level, the blood CD3+, CD4+ and CD4/CD8 levels were significantly decreased immediately after surgery, on the first and second postoperative days in the two groups (P<0.01), which returned to baseline values on the fifth postoperative day (P>0.05). On the fifth postoperative day, CD3+, CD4+ and CD4/CD8 levels in adult group were significantly higher than those in elder group (P<0.05). Conclusion: The postoperative immune function in elder patients recovered more slowly than that in adult. | Lairong Sun Lianbing Gu Zongli Shen Yueqing Zhu Yanning Qian | 2010 | The Chinese-German Journal of Clinical Oncology2010，9，4： | 0 |
