  • Current status and research progress of medical therapy for high-grade gliomas

    High-grade gliomas are the most common malignant primary central nervous system tumors with poor prognosis. The operation based on the principle of maximum safe resection of tumors, combined with radiation therapy and chemotherapy, is the primary treatment method. This treatment only delays the progression of high-grade gliomas, and almost all patients eventually develop disease progression or relapse. With the development of molecular biology, immunology, and genomics, people have a deeper understanding of the pathogenesis of gliomas. Targeted therapy, immunotherapy, and other comprehensive treatments are expected to become potential treatments for high-grade gliomas. This article reviews the current status of medical treatment of primary and recurrent high-grade gliomas, and the research progress of high-grade gliomas in targeted therapy and immunotherapy.

  • Direct Coronary Stenting vs. Conventional Stenting in Treating Coronary Heart Disease: A Meta-Analysis

    Objective To assess the safety and effectiveness of direct stenting (DS) versus conventional stenting (CS) with predilation in clinical practice. Methods Such databases as PubMed, EMbase, The Cochrane Library (Issue 3, 2011), CBM, VIP and CNKI were searched from the date of their establishment to April 2011, to collect the randomized controlled trials (RCTs) on DS vs. CS. The quality of RCTs was critically appraised, and the data were extracted and cross-checked by two reviewers independently. Meta-analyses were conducted using RevMan 5.0 software. Results A total of 24 RCTs involving 6 666 patients were included. The results of Meta-analyses showed that DS took shorter operative time compared with CS (MD=–3.36, 95%CI –4.41 to –2.30, Plt;0.000 01) with acute gain (luminal diameter) during operation (MD=–0.01, 95%CI –0.04 to 0.02, P=0.64). But there were no significant differences in the incidence of major adverse cardiac events during six-month follow-up (OR=0.89, 95%CI 0.69 to 1.14, P=0.35) and restenosis (OR=1.02, 95%CI 0.82 to 1.26, P=0.88). Conclusion Current evidence shows that DS is not superior to CS. This conclusion still needs to be further proved by well-designed and large scale RCTs with longer follow-up duration.

  • Application and research progress of subtalar distraction bone block arthrodesis in treatment of calcaneus fracture malunion

    Objective To review the application and research progress of subtalar distraction bone block arth-rodesis in the treatment of calcaneus fracture malunion. Methods The recent literature concerning the history, surgical technique, postoperative complication, indications, and curative effect of subtalar distraction arthrodesis with bone graft block interposition in the treatment of calcaneus fracture malunion was summarized and analyzed. Results Subtalar distraction bone block arthrodesis is one of the main ways to treat calcaneus fracture malunion, including a combined surgery with subtalar arthrodesis and realignment surgery for hindfoot deformity using bone block graft. The advantage is on the base of subtalar joint fusion, through one-time retracting subtalar joint, the posterior articular surface of subtalar joint implants bone block can partially restore calcaneal height, thus improving the function of the foot. Compared with other calcaneal malunion treatments, subtalar distraction arthrodesis is effective to correct complications caused by calcaneus fracture malunion, and it can restore the height of talus and calcaneus, correct loss of talocalcaneal angle, and ease pain. Conclusion Subtalar distraction bone block arthrodesis has made remarkable progress in the treatment of calcaneus fracture malunion, but it has the disadvantages of postoperative nonunion and absorption of bone block, so further study is needed.

  • Safety analysis of thulium laser in thoracoscopic pulmonary wedge resection

    Objective To explore the feasibility and safety of 2 μm thulium laser in thoracoscopic wedge resection. Methods The clinical data of 137 patients who underwent thoracoscopic wedge resection with thulium laser (as a thulium laser group, 64 patients, including 22 males, 42 females, average age of 58.39±10.40 years) and staplers (as a stapler group, 73 patients, including 33 males, 40 females, average age of 60.79±10.96 years) in thoracic Department of Xuanwu Hospital between April 2016 and August 2018 were retrospectively analyzed. In the study, the intraoperative blood loss, the operative time, chest tube duration, daily amount of fluid leak, hospital stay and hospitalization costs were compared between two groups. Results The intraoperative blood loss of the thulium laser group (16.05±23.67 mL) was significantly shorter or lower than that of the stapler group (28.56±32.09 mL) (P=0.011). Besides, the post operation hospital stay and hospitalization costs of the thulium laser group (4.72±2.49 d, 37 127.33±9 302.14 yuan) were also significantly shorter or lower than those of the stapler group (5.67±2.02 d, 49 545.76±13 831.93 yuan) (P=0.015, P=0.000). Furthermore, no statistical difference was found between the thulium laser group and the stapler group in the operative time (116.38±41.91 min vs. 108.36±47.25 min), total hospital stay (10.13±2.98 d vs. 11.05±3.26 d), daily amount of fluid leak (138.38±72.23 mL vs. 152.7±77.54 mL), chest tube duration (2.89±2.34 d vs. 3.52±1.48 d) and the frequency of postoperative fever (0.89±1.55 times vs. 1.23±1.70 times). Conclusion Applying 2 μm thulium laser to thorascopic wedge resection is safe and feasible. Besides, 2 μm thulium laser can achieve a similar result to that of the standard technique by using staplers.
