OBJECTIVE: To modify the design of the Achilles tendon-scar composite flap into the Z-shape and to apply it into clinic situations to correct the tendon-scar contracture after burn and other injures. METHODS: According to degree of contracture and strephenopedia, the central limb of Z-shaped design lay in contracture line of posterior ankle area just over the Achilles tendon and extended 8 to 12 cm in length. Lateral limbs extended 5 to 8 cm and usual angles of the Z-shape was 60 degrees. The two tendon-scar composite flaps were made and slipped along the central limb between them. From March 1994 to August 1999, seven patients with Achilles tendon scar contracture were operated with this method. RESULTS: Excellent relieving of the Achilles tendon-scar contractue was achieved. No such complications happened as ischemia and necrosis of the flaps. CONCLUSION: The Z-shaped tendon-scar composite flap is practical in clinics. It is characterized by abundant blood supply, easily procedure and reliable result.
As an advanced mode of diagnosis and treatment, day surgery is widely carried out in foreign countries. Although it started late in China, it has been gradually valued and vigorously promoted in medical and health field in recent years. The effective implementation of day surgery in hospital cannot be separated from the strong support of performance management system. Through introducing the performance management experiences in promoting day surgery mode in West China Hospital of Sichuan University, this article discusses how to construct an effective whole-course performance management system for day surgery combined with operation management through three mechanisms: the management committee mechanism, the operation management mechanism and the performance assessment mechanism, which are based on the structure-process-outcome dimensions of quality management system, at the three levels of hospital, department and position, so as to provide a reference for developing day surgery in China.

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.

【摘要】 目的 探討深吸氣量（inspiratory capacity，IC）與慢性阻塞性肺疾病（chronic obstructive pulmonary disease，COPD）患者臨床特征的相關性。 方法 2009年12月-2010年6月納入84例穩定期COPD患者，測定6分鐘步行試驗（6-minute walk test，6MWT）、圣喬治生活問卷評分（St George′s respiratory questionnaire，SGRQ）及肺功能檢查:第1秒用力呼氣容積（forced expirotovy volume in one second，FEV1）、IC、IC與肺總量（total lung capacity，TLC）比值（IC/TLC）等相關指標，并進行相關性分析。 結果 6MWT值與FEV1無明顯直線相關（r=0.14，Pgt;0.1）；6MWT值與FEV1≥60%無明顯直線相關（r=0.16，Pgt;0.1）；6MWT值與IC值呈正的直線相關（r=0.317，Plt;0.01）；6MWT值與IC/TLC值呈正的直線相關（r=0.274，Plt;0.01）；SGRQ值與FEV1呈負的直線相關（r=-0.307，Plt;0.01）；SGRQ值與IC值無直線相關（r=-0.001，Pgt;0.25）；SGRQ值與IC/TLC值無直線相關（r=-0.003，Pgt;0.25）。 結論 對COPD患者，IC比FEV1更準確地反映患者的運動耐量的程度，FEV1比IC更準確地反映患者呼吸困難的嚴重程度。【Abstract】 Objective To explore the relationship between the inspiratory capacity (IC) and clinical characters of stable chronic obstructive pulmonary disease (COPD). 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 investigate the prognostic differences and decision-making role in postoperative radiotherapy of four molecular subtypes in pT1-2N1M0 stage breast cancer. Methods The clinicopathological data of 1526 patients with pT1-2N1M0 breast cancer treated at West China Hospital of Sichuan University between 2008 and 2018 were retrospectively analyzed. χ2 test was used to compare the clinicopathological features among patients with different molecular subtypes. Kaplan-Meier survival analysis and log-rank test were used to draw the survival curves and compare the overall survival (OS) and breast cancer-specific survival (BCSS) among patients with different molecular subtypes. Cox regression model was used to determine the influencing factors of OS of patients after radical mastectomy. Results Among the 1526 patients with pT1-2N1M0 breast cancer, there were 674 cases (44.2%) of Luminal A subtype, 530 cases (34.7%) of Luminal B subtype, 174 cases (11.4%) of human epidermal growth factor receptor 2 (Her-2) overexpression subtype, and 148 cases (9.7%) of triple-negative subtype. The 5-year OS rates of Luminal A, Luminal B, Her-2 overexpression and triple negative patients were 98.6%, 94.3%, 95.5% and 91.2%, respectively (χ2=11.712, P=0.001), and the 5-year BCSS rates were 99.3%, 94.6%, 95.5% and 92.5%, respectively (χ2=18.547, P<0.001). Multiple Cox regression analysis showed that menstrual status [hazard ratio (HR)=0.483, 95% confidence interval (CI) (0.253, 0.923), P=0.028] and whether endocrine therapy [HR=2.021, 95%CI (1.012, 4.034), P=0.046] were prognostic factors for the 5-year OS rate of breast cancer patients after radical mastectomy (P<0.05). However, it failed to reveal that Luminal subtypes and postoperative radiotherapy were prognostic factors for the 5-year OS rate (P>0.05). Conclusions In pT1-2N1M0 breast cancer patients, the 5-year OS rate and 5-year BCSS rate in triple-negative patients are the lowest. The relationship between Luminal classification, postoperative radiotherapy and survival in patients after radical mastectomy needs further study in the future.
【Abstract】 Objective To explore the biomechanical properties of a new intramedullary controlled dynamicnail ing (ICDN). Methods Ten pairs of specimens of adult femurs, with the age of 18 to 55 years, were divided into twogroups (groups A1 and B2, n=10). The length of the specimens was (438 ± 10) mm , and the external diameter was (26.4 ± 1.5) mm. The specimens of the two groups were osteotomized transversely after the biomechanical test. ICDNs and GK nails were randomly implanted into the femurs, respectively (groups A2 and B2). Torsional, bending and axial compressive tests were made in each group, and the effect of dynamic compression between the fracture fragments was tested. Results The resistance to compression of groups A1, B1, A2 and B2 were (0.19 ± 0.18) × 106, (0.22 ± 0.12) × 106, (1.67 ± 0.68) × 106 and (0.86 ± 0.32) × 106 N/mm, respectively. There was statistically significant difference between groups A2 and B2 (P lt; 0.01). The bending stiffnesses of coronal section of groups A1, B1, A2 and B2 were (0.94 ± 0.25) × 103, (1.10 ± 0.21) × 103, (0.70 ± 0.22) × 103, (0.64 ± 0.21) × 103 N/mm, respectively. The bending stiffness of sagittal plane of groups A1, B1, A2 and B2 were (1.06 ± 0.26) × 103, (0.96 ± 0.25) × 103, (0.67 ± 0.25) × 103, (0.61 ± 0.18) × 103 N/mm, respectively. There were no statistically significant differences between groups A1 and B1 or between groups A2 and B2 (P gt; 0.05). When the torque was 5 Nm, the torsional stiffness of groups A1, B1, A2 and B2 were (4.00 ± 2.54), (4.76 ± 1.93), (0.50 ± 0.63), (0.35 ± 0.31) Nm/°, respectively. When the torque was8 Nm, the torsional stiffness of groups A1, B1, A2 and B2 were (4.30 ± 3.27), (3.94 ± 2.01), (0.42 ± 0.52), (0.36 ± 0.18) Nm/°, respectively. There were statistically significant differences between groups A1 and A2 or between groups B1 and B2 (P lt; 0.05), and no statistically significant difference between between groups A2 and B2 (P gt; 0.05). The average maximal pressure generated between the fracture fragments which were fixed with ICDN was 21.6 N, and the pressure between the fracture fragments which were fixed with GK nail ing could not be tested. Conclusion The design of ICDN conforms to the special anatomical structure of the femur. ICDN could provide a completely different structure, a different fixation principal and a more balancedfixation than GK nail. ICDN incorporates the flexible and rigid fixation, which is l ikely to be the trend of the fracture fixation.
Objective To analyze the efficacy of breast-conserving surgery with adjuvant radiation therapy (BCS+RT) vs. mastectomy (MAST) for early breast cancer among young Chinese patients. Methods Young female breast cancer patients (≤40 years old) treated at West China Hospital of Sichuan University between January 1st, 2008, and December 31st, 2019 were analyzed for clinical staging, molecular subtypes, surgical techniques, and prognostic assessments using follow-up data. Results Of 974 eligible patients in this study, 211 underwent BCS+RT and 763 underwent MAST. The Kaplan-Meier analyses indicated that there was no significant difference in the 5-year locoregional recurrence-free survival rate (99.1% vs. 99.4%, P=0.299), distant metastasis-free survival rate (97.9% vs. 96.4%, P=0.309), breast cancer-specific survival rate (100.0% vs. 97.0%, P=0.209), or overall survival rate (99.4% vs. 96.8%, P=0.342) between patients who underwent BCS+RT and those who underwent MAST. The multiple Cox proportional hazards regression analyses revealed that the treatment approach (BCS+RT or MAST) did not significantly predict locoregional recurrence-free survival (P=0.427), distant metastasis-free survival (P=0.154), breast cancer-specific survival (P=0.155), or overall survival (P=0.263). Subgroup analyses showed that there was no statistically significant difference in survival outcomes between BCS+RT and MAST in different clinical stages or molecular subtypes. Clinical stage and molecular subtype should also not be regarded as independent factors in deciding the treatment approach. Conclusions Receiving BCS+RT or MAST treatment does not affect the survival outcomes of young early-stage breast cancer patients, showing similar efficacy across various clinical stages and molecular subtypes. Choosing BCS+RT is considered safe for early-stage young female breast cancer patients eligible for breast conservation.
