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.

【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 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.
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...
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.

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.
