Objective To elucidate the protective effect of leukocyte depletion on the myocardium during the settings of myocardial reperfusion injury. Methods Twenty patients undergoing cardiopulmonary bypass with continuous infusion of blood cardioplegia were randomized into two groups:the control group (n=10) with no leukocyte depletion filter used, and the experimental group (n=10) with the use of leukocyte depletion filter on the bypass circuit. The blood cells count before and after the filtration were measure...
Abstract： Objective To introduce the new procedure of endobronchial ultrasoundguided transbronchial needle aspiration (EBUSTBNA) for staging lung cancer and diagnosing thoracic diseases, in order to determine its value in the evaluation of thoracic diseases. Methods We retrospectively reviewed the data of all patients examined with EBUSTBNA our institution between September 2009 and May 2010. Among the patients, there were 75 males and 31 females with an average age of 62.3 years old. Based on their primary indication, we divided all the 106 patients into three categories. (1) There were 76 patients with known or bly suspected lung cancer. Enlarged mediastinal lymph nodes on radiographic examination of the chest (≥1.0 cm) were detected in all the patients. (2) There were 22 patients with enlarged mediastinal lymph nodes or mediastinal masses of unknown origin. (3) There were 8 patients with pulmonary mass located close to the central airways. Results (1) 76 patients underwent EBUSTBNA for known or bly suspected lung cancer. Among them, 58 patients were confirmed to have mediastinal lymph nodes metastasis on EBUSTBNA. Sixteen in the 18 patients with negative EBUSTBNA underwent thoracoscopy or thoracotomy for pulmonary resection and mediastinal lymph node dissection. Postoperative pathology confirmed that 12 patients did not have metastatic nodes, 2 patients had metastatic nodes and 2 other patients had benign lesions within the lung. The diagnostic sensitivity, specificity and accuracy of EBUSTBNA for the mediastinal staging of lung cancer were 96.66%(58/60), 100.00%(12/12) and 97.22%(70/72), respectively. (2) 22 patients underwent EBUSTBNA for the evaluation of mediastinal adenopathy or mass in the absence of any identifiable pulmonary lesion. Among them, 7 had malignancy, 13 had benign diseases on EBUSTBNA and the sensitivity of EBUSTBNA in distinguishing malignant mediastinal diseases was 87.50% (7/8). (3) 8 patients with pulmonary mass located close to the central airways were accessed by EBUSTBNA. Definite diagnosis was achieved in 7 patients, and lung cancer was detected in 6 patients. The sensitivity and the diagnostic accuracy of EBUSTBNA for the diagnosis of unknown pulmonary mass was 85.71%(6/7) and 87.50%(7/8), respectively. All the procedures were uneventful, and there were no complications. Conclusion EBUSTBNA is a highly effective and safe procedure. We believe that EBUSTBNA should be used routinely in the diagnosis and staging of thoracic diseases.
Objective To investigate the clinical effects and the brain protection effect of different cardiopulmonary bypass in treating descending aortic aneurysms. Methods From January 2001 to December 2008, 65 patients were diagnosed to have descending aortic aneurysm with magnetic resonance imaging (MRI) in our hospital. Among them, there were 56 males and 9 females whose age was between 15 and 71 years old with an average of 48.1 years. The disease process ranged from 6 days to 4 months (19.0±6.5 d ). Preoperative diagnosis showed that there were 41 cases of DeBakey type Ⅲinterlayer, 9 cases of Marfan syndrome with postoperative complications of type Ⅲ interlayer, 7 cases of pseudoaneurysm and 8 cases of true aneurysm. We adopted artificial blood vessel repair patch to repair the damaged point of the descending aorta in 2 cases, performed vascular aneurysm resection and artificial vessel replacement on 63 patients, and carried out descending aorta replacement and intercostal artery grafting in 18 cases. Results Among the 65 cases of cardiopulmonary bypass patients, there were 13 cases of left heart bypass, 12 cases of heart bypass, 30 cases of deep hypothermic circulatory arrest (DHCA) with total body retrograde perfusion (TBRP) and 10 cases of modified separate perfusion of upper and low body. Cardiopulmonary bypass time, DHCA time, retrograde perfusion time, upper body circulatory arrest time and low body circulatory arrest time were respectively 51-212 min, 18-75min, 18-73 min, 21-31 min, and 39-67 min. No death occurred during the operation, and there were no brain complications or complications of paralysis among all the patients. Two patients died after operation because of renal failure. Conclusion Good results can be achieved by selecting different method of cardiopulmonary bypass based on the anatomical location and range of the thoracic descending aortic aneurysms. The selection criteria should be favorable to the surgical operation and organ protection.
Objective To summarize our experience of using rigid bronchoscopy in the managent of patients with tracheobronchial disease. Methods From Sep.2002 to Nov.2007, 44 patients of tracheobronchial disease（31 men，13 women, median age 51.9 years) underwent rigid bronchoscopic operations. All procedures were carried out under general anesthesia with high frequency jet ventilation. After the rigid bronchoscope was placed in the main trachea through the mouth , the airway was checked out firstly, and then the lesion was removed by repeated freezing, argon plasma coagulation, cauterization or mechanical ablation, and a stent maybe implanted while needed. Results All 54 procedures were accomplished endoscopically without mortality or major morbidity (16 clearence,19 core out,8 scar clearance,3 foreign body removal, 8 stent insert or removal).The lesion located at trachea in 19 cases, at carina in 4 cases,at left main bronchus in 11 cases and at right main bronchus in 10 cases. There were 17 benign diseases and 27 malignant diseases. There were 3 slight complications. 16 patients compliating with benign disease were followed-up and 1 patient was missed,there was no tumor recurrence except 3 patients complicating with tracheal scar who received reoperations during 4-44 (mean 23.0) months follow-up period. Of the 27 malignant cases,23 patients were followed-up and 4 patients were missed, the follow-up period were 5-58(mean 27.1)months.3 patients died in one months after operation of other disease; the other patients all survived more than one month,especially 7 patients who received radical resection of the tumor survived more than one year. Conclusions These data show that rigid bronchoscope can be applied safely and effectively in the management of tracheobronchial disease.

Abstract: Objective To summarize the clinical experiences of videoassisted thoracoscopic surgery (VATS) lobectomy performed on a series of 300 consecutive patients, and report the results of a 3year followup. Methods We retrospectively analyzed the clinical data of 300 consecutive patients who underwent VATS lobectomy from September 2006 to December 2009 in the Department of Thoracic Surgery, People’s Hospital of Peking University. Of the 300 patients, there were 159 males and 141 females with the age ranged from 18 to 86 years (58.30±13.90 years). Preoperative diagnosis showed that there were 266 patients of mass in the lung, 22 of bronchiectasis, 5 of cyst/abscess in the lung, 3 of pulmonary sequestration, 2 of fungus infection, and 2 of pneumothorax. We assessed the perioperative variables by standard descriptive statistics and estimated the 3year survival rate by KaplanMeier analyses. Results Sixtysix patients were diagnosed to have benign diseases and 234 patients were with malignancies. A percentage of 81.82% (54/66) of the benign patients had infectious diseases, and the majority of the malignancies was nonsmall cell lung cancer (213 patients), especially adenocarcinomas which comprised 73.08% (171/234) of all the malignancies. A total of 273 patients accomplished VATS lobectomy, of whom 27 patients required conversion to thoracotomy at a conversion rate of 9.00%(27/300). In the VATS lobectomy accomplished group, the mean operation time was 317±088 h, and the blood loss was 225.70±195.20 ml. Benign surgery took significantly less time (t=2.280, P=0.0032) and had shorter drainage time(t=1.392, P=0.0304) than those of malignancies. Dense adhesions between lymph nodes and blood vessels was the primary reason for conversion to thoracotomy in 17 patients at a percentage of 62.96%(17/27). Bleeding was the second reason for conversion in 5 patients at a percentage of 1852%. The patients in the upper lobe lobectomy group showed significantly higher risk of conversion compared with those in the nonupper lobe surgery group (χ2=6.131, P=0.013), while gender (χ2=1.182, P=0.277), pathology (χ2=0.210, P=0.647) and the tumor located in left or right side(χ2=2.933, P=0.087) didn’t influence the risk of conversion. The result of the 3year followup showed that there was no reoccurrence of symptoms in patients with benign diseases; Nonsmall cell lung cancer patients had a 3year survival rate of 0.87 with the 95% confidence interval (CI) from 0.77 to 0.96, and pathologic stage I patients at 0.91 with the 95%CI from 0.85 to 0.98. Conclusion VATS lobectomy is safe and effective. This research shows that domestic technologies of VATS lobectomy and its midterm results have reached the international standard.
ObjectiveTo compare the patient-reported outcomes regarding function, joint amnesia, and the quality of life after unicompartmental knee arthroplasty (UKA) and total knee arthroplasty (TKA). Methods The clinical data of patients who received UKA or TKA between September 2017 and June 2018 were retrospectively analyzed. After propensity score matching, 40 patients (40 knees) each in TKA group and UKA group were finally included in the study. There was no significant difference between the two groups in gender, age, body mass index, surgical side, preoperative knee range of motion, Western Ontario and McMaster University Osteoarthritis Index (WOMAC) score, clinical and function scores of knee society score (KSS) (P>0.05). At 2 years after operation, WOMAC score, KSS clinical and function scores were performed on the two groups of patients, and compared with preoperative ones; knee injury and osteoarthritis outcome score-physical function short form (KOOS-PS), short-form 36 health survey scale (SF-36 scale), and forgotten joint score (FJS) were also performed. Results At 2 years after operation, the total score of WOMAC, the clinical and function scores of KSS in the two groups significantly improved when compared with preoperative ones (P<0.05), but there was no significant difference in the total score of WOMAC, the individual score of WOMAC, the clinical and function scores of KSS between the two groups (P>0.05). The total KOOS-PS score in the UKA group was significantly lower than that in the TKA group (t=4.243, P=0.000), and the scores of writhing/knee rotation, kneeling, and squatting in the UKA group were significantly lower than those in the TKA group (P<0.05). The total FJS score in the UKA group was significantly higher than that in the TKA group (t=?6.334, P=0.000). In the UKA group, the scores of 7 items were significantly lower than those of the TKA group (P<0.05) including when walking over 15 minutes, when climbing stairs, when walking on uneven ground, when standing for long periods, when doing housework or gardening, when taking a walk or hiking, and when doing your favorite sport. The SF-36 scales of physiological function, energy, social function, emotional function, and mental health in the UKA group were significantly higher than those in the TKA group (P<0.05). Conclusion Compared with TKA, patients treated with UKA may have better knee function recovery, joint amnesia, and higher quality of life.

Methods Between December 2009 and June 2010, 84 patients with stable COPD were enrolled. Lung function (FEV1, IC, IC/TLC) ,6 minute walk-test (6MWT) and St George′s respiratory questionnaire (SGRQ) were examined. The relationship among FEV1, IC, IC/TLC, and the results of 6MWT and SGRQ by Pearson correlation analysis. Results There was no linear correlation between 6MWT and FEV1 （r=0.14，Pgt;0.1）, and 6MWT and FEV1≥60% （r=0.16，Pgt;0.1）. There was positive correlation between 6MWT and IC （r=0.317，Plt;0.01）, and 6MWT and IC/TLC （r=0.274，Plt;0.01）. There was negative correlation between SGRQ and FEV1 （r=-0.307，Plt;0.01）; and no linear correlation between SGRQ and IC （r=-0.001，Pgt;0.25）, and SGRQ and IC/TLC （r=-0.003，Pgt;0.25）. Conclusion In stable COPD patients, IC may be more accurate than FEV1 in refection of exercise tolerance while FEV1 may be more sensitive than IC in evaluation of dyspnea.
Objective To explore a scientific disease cost accounting. Method Disease cost accounting = disease cost accounting of clinic pathway + disease basis cost accounting. Conclusions It is the tendency with the medical reform for the social security department to pay by disease for the hospitals, as a result, both social security department and hospitals have to resort to the scientific way in terms of cost accounting of disease. And it is practical and effective by means of cost accounting for clinic pathway.
