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.
Uveal melanoma is the most common primary intraocular malignancy in adults. Although it is relatively rare, it is extremely malignant, with poor treatment effect. The current treatment for primary lesions can achieve ideal local control, but there are still nearly half of the patients with distant metastasis. This article reviews the epidemiology, genetic status, diagnosis, treatment and prognosis of uveal melanoma in combination with recent advances in diagnostic and therapeutic techniques.
Metastatic renal cell carcinoma accounts for 20%-30% of newly diagnosed renal cell carcinoma and its prognosis is poor. It is not sensitive to radiotherapy or chemotherapy, and traditional cytokine therapy has limited efficacy in patient with metastatic renal cell carcinoma. In recent years, with the emergence of targeted drugs and immune checkpoint inhibitors, the survival of patients with metastatic renal cancer has been greatly improved. This article reviews treatment and research progress of metastatic renal cell carcinoma. It mainly introduces the medical treatment, including cytokine therapy, targeted therapy and emerging immunotherapy, and further analyzes the value of cytoreductive nephrectomy in the context of targeted therapy. The purpose of this article is to provide evidence for reasonable choices of treatment regimens in order to better guide clinical treatment.
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.
Objective To review the progress of treatments for old calcaneal fractures. Methods The related literature of treatments for old calcaneal fractures were reviewed and analyzed from the aspects such as the pathoanatomy, classifications, and surgical treatments. Results Old calcaneal fractures are common in clinical, the anatomical changes are very complicated. In addition to classical open reduction and internal fixation, arthrodesis, and osteotomy, techniques of minimally invasive operation, external fixator, and three-dimensional printing are more and more widely applied, treatments for old calcaneal fractures nonunion have also received increasing attention. Conclusion Although the perfect strategy for treating old calcaneal fractures has not yet been developed, great progress has been achieved recently, the personalized therapy need to be further studied, and therapies for the early stage old calcaneal fractures and old calcaneal fractures nonunion need to be further explored.

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.
ObjectivesTo systematically review the application of evidence-based medicine (EBM) combined with problem-based learning (PBL) method in clinical teaching.MethodsDatabases including WanFang Data, CNKI, VIP, CBM, PubMed and EMbase were searched to identify eligible randomized controlled trials that compared EBM plus PBL with traditional lecture based learning (LBL) method in clinical teaching from inception to March 28th, 2020.

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.
Objective To compare the safety and efficacy of thulium laser wedge resection of the lung under uniportal thoracoscopy with the other two traditional surgical methods (mechanical cutting stapler wedge resection and segmentectomy) in the treatment of small pulmonary nodules.MethodsClinical data of 125 patients with small pulmonary nodules receiving uniportal video-assisted thoracoscopic surgery from December 2017 to December 2018 in our hospital were retrospectively analyzed. Among them, 33 patients had thulium laser wedge resection (a thulium laser group), including 10 males and 23 females, with an average age of 59.21±11.31 years; 48 patients had mechanical stapling pulmonary wedge resection (a mechanical stapling pulmonary wedge resection group), including 17 males and 31 females, with an average age of 57.27±11.30 years; and 44 patients had pulmonary segmentectomy (a pulmonary segmentectomy group), including 21 males and 23 females, with an average age of 63.00±9.68 years. The surgical margin air leakage, operation time, intraoperative blood loss, postoperative hospital stay, drainage days, average daily drainage volume, fever, pain and hospitalization expenses were compared among the three groups. ResultsThe body mass index, gender, smoking history, benign and malignant pathological results, average maximum diameter of lesions and lesion location distribution were not statistically different among the three groups (P>0.05). The average age and the proportion of pleural adhesions in the thulium laser group were not statistically different from those of the other two groups (P>0.05). In the distribution of the number of lesions, the proportion of multiple lesions in the mechanical stapling pulmonary wedge resection group was higher than that of the other two groups, and there was no statistical difference between the other two groups. The intraoperative blood loss in the thulium laser group was less than that of the other two groups (P≤0.05). There was no statistical difference in the classification of surgical margin air leakage or the operation time among the three groups (P>0.05). The proportion of postoperative fever and hospitalization expenses in the thulium laser group were lower or less than those of the other two groups (P<0.05). The length of hospitalization stay and postoperative chest tube placement in the thulium laser group was significantly shorter than that of the pulmonary segmentectomy group (P<0.05), which was not statistically different from the mechanical stapling pulmonary wedge resection group (P>0.05). There was no statistical difference in the average daily drainage volume or the proportion of pain among the three groups (P>0.05). Conclusion The thulium laser wedge resection under uniportal thoracoscopy is a safe, effective and economical method for the treatment of small pulmonary nodules.
