目的交流肝脏外伤非手术治疗的病例选择与治疗体会。方法对该院57例非手术治疗的肝脏外伤病例资料进行回顾性分析。结果57例肝脏外伤患者中55例经非手术治疗后痊愈出院，另2例在治疗过程中经中转手术治愈，全组病例无一例死亡。结论对经过严格选择的肝脏外伤病例进行非手术治疗，疗效肯定，也是安全可行的。CT检查在病例选择中具有非常重要的作用。
Objective To investigate the effectiveness of double-needle suture for mixed meniscus tear repair under arthroscope. Methods Between April 2006 and January 2011, 22 patients with mixed meniscus tear were treated with double-needle suture under arthroscope. There were 14 males and 8 females, aged 18-41 years (mean, 31.3 years). All injuries were caused by sports. The time between injury and admission ranged from 2 days to 4 years (median, 11 months). International Knee Documentation Committee (IKDC) score was 42.5 ± 15.2, Lysholm score was 45.5 ± 13.5, and Tegner score was 2.9 ± 1.6. Seventeen cases complicated with anterior cruciate ligament injury. Results Healing of incision by first intention was achieved in all patients. No injury of nerve and blood occurred. The patients were followed up 12-48 months with an average of 27.6 months. According to Barrett et al. standard, 19 cases (86%) got clinical healing. The IKDC, Lysholm, and Tegner scores were improved to 77.1 ± 8.9, 79.8 ± 9.9, and 6.8 ± 1.6 respectively at last follow-up, showing significant differences when compared with preoperative scores (P lt; 0.05). Conclusion Arthroscopic meniscus repair using double-needle suture can provide good effectiveness because it has high firmness.
Based on the guidelines of the diagnostic test systematic review, this study elaborated the statistical processing of the pooling of data detailed in the systematic review of diagnostic test, discussed the methods for identification and handling of the heterogeneity, evaluated the advantages and disadvantages of the index of the accuracy in diagnostic tests, and proposed the identification method of the publication bias. It also took the data from the published article entitled “Diagnostic Value of ProGRP and NSE for Small Cell Lung Cancer: A Meta-Analysis” as an example for analysis and illustration, which presented clearly the data processing and interpretation of the systematic review of diagnostic test, in order to provide references for clinical researchers to study and conduct the systematic review of diagnostic test.
Objective To analyze the effectiveness of flexible internal fixation with locking plate for distal femoral fractures. Methods Between January 2015 and June 2016, 21 cases of distal femoral fractures were treated. There were 5 males and 16 females with an average age of 62 years (range, 32-88 years). Injury was caused by falling in 14 cases, by traffic accident in 5 cases, and by falling from height in 2 cases. The fractures located at the left side in 13 cases and the right side in 8 cases. Twenty cases were fresh closed fractures and 1 case was open fracture. According to AO/Association for the Study of Internal Fixation (AO/OTA) typing, there were 5 cases of type 33-A1, 3 of type 33-A2, 8 of type 33-A3, 2 of type 33-C2, and 3 of type 33-C3. The time from injury to operation was 3-13 days (mean, 6.5 days). Results All operation incisions healed primarily. Eighteen patients were followed up 12-24 months (mean, 16 months). All fractures healed, and the healing time was 8-24 weeks (mean, 16.6 weeks). The articular surface was smooth and the thigh length was recovered. No screw loosening, plate breakage, valgus or varus of the knee, stiff of the knee or non-unions occurred during follow-up. There was no significant difference in visual analogue scale (VAS) score between at 6 and 12 months after operation (P>0.05), and the difference was significant bewteen the other time points (P<0.05). There were significant differences in the range of motion of knee between 1 month and 3, 6, 12 months (P<0.05); there was no significant difference between 3, 6, and 12 months (P>0.05). There were significant differences in the Neer scores between 1, 3, 6, and 12 months after operation (P<0.05). According to Neer score criteria, the results were excellent in 12 cases and good in 6 cases at 12 months after operation. Conclusion Flexible internal fixation with locking plate for distal femoral fractures can get good functional recovery.
