  • Effectiveness of arthroscopic microfracture combined with osteochondral autologous transplantation for large area cartilage injury of femoral condyle of knee

    ObjectiveTo explore the effectiveness of arthroscopic microfracture combined with osteochondral autologous transplantation (OAT) in treatment of large area (4-6 cm2) cartilage injury of the femoral condyle of knee.MethodsBetween March 2016 and June 2017, 22 patients of large area cartilage injury of the femoral condyle of knee were treated with arthroscopic microfracture combined with OAT. There were 16 males and 6 females with an average age of 22-60 years (mean, 38.6 years). The cause of injury was traffic accident in 8 cases and sports injuries in 14 cases. The disease duration was 1-6 months (mean, 3.4 months). There were 15 cases of medial femoral condyle injuries and 7 cases of lateral condyle injuries. The area of cartilage defect was 4-6 cm2 (mean, 4.98 cm2). According to the International Cartilage Repair Society (ICRS) classification, 9 cases were rated as grade Ⅲ and 13 cases as grade Ⅳ. Eighteen cases were combined with meniscus injuries. Preoperative visual analogue scale (VAS) score was 6.36±1.25 and Lysholm score was 36.00±7.77.ResultsAll incisions healed by first intention. All patients were followed up 2-3 years with an average of 2.3 years. At 2 years after operation, the VAS score was 1.27±0.94 and the Lysholm score was 77.82±6.21, which were significantly improved when compared with those before operation (t=16.595, P=0.000; t=21.895, P=0.000). At 2 years after operation, MRI showed that the cartilage defect was repaired well.ConclusionArthroscopic microfracture combined with OAT can be used to treat large area cartilage injury of the femoral condyle of knee, and the good early effectiveness can be obtained.

  • Effectiveness and safety of thrombolytics for patients with ST-segment elevation myocardial infarction in China: a network meta-analysis

    ObjectiveTo systematically review the effectiveness and safety of thrombolytics for treating ST-segment elevation myocardial infarction (STEMI) in China by network meta-analysis.MethodsThe PubMed, EMbase, The Cochrane Library, Web of Science, CBM, WanFang Data, and CNKI databases were searched for randomized controlled trials (RCTs) of thrombolytics for Chinese patients with STEMI from inception to October 2016. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Statistical analysis was performed by WinBUGS 1.4.3 software and R 3.3.1 software.ResultsA total of 32 RCTs involving 3 164 patients with 7 types of thrombolytics were included. The results of network meta-analysis showed: the urokinase had lower reperfusion rate than tenecteplase (rhTNK-tPA), reteplase, alteplase, and pro-urokinase (all P values <0.05), however, had higher mortality or major adverse cardiovascular events rates than rhTNK-tPA, reteplase, alteplase, and pro-urokinase (all P values <0.05), and higher incidence of non-intracranial hemorrhage than those of alteplase and pro-urokinase (both P values <0.05). The incidence of intracranial hemorrhage had no statistical differences among different thrombolytics (all P values >0.05). The results of area under the cumulative ranking curve which ranked effectiveness of all thrombolytics showed that rhTNK-tPA had the best effectiveness and urokinase had the relative worst effectiveness among different thrombolytics.ConclusionsThe current evidence shows that domestic rhTNK-tPA may be effective in thrombolytic treatment. Due to limited quality and quantity of the included studies, more high-quality studies are needed to verify the above conclusion.

  • Application of methylene blue staining for precise positioning of small esophageal leiomyoma during video-assisted thoracoscopic surgery via one utility port

    Objective To develop a novel methylene blue staining technique to localize small esophageal leiomyomas (<1.5 cm) and evaluate its feasibility. Methods Between January 2013 and October 2016, 9 patients with small esophageal leiomyomas (<1.5 cm) underwent thoracoscopic enucleation in Tongji Hospital. There were 5 males and 4 females with an average age of 51 years. We preoperatively injected 0.5–1.0 ml methylene blue in the submucosa adjacent to the tumors under the guidance of gastroscope. Then, we transferred the patients to the operating room. Results Staining was successful in 9 patients. The unstained tumor was exposed after the blue-stained mediastinal pleura and overlying muscle were incised longitudinally during video-assisted thoracoscopic surgery via one utility port. No abnormalities were detected in the esophageal mucosa. No major complications, such as esophageal leakage or esophageal diverticulum occurred. Conclusion Endoscopic methylene blue staining is safe and feasible for localizing small esophageal leiomyomas during video-assisted thoracoscopic surgery via one utility port. This method will enable enucleation precise and easy.
