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.
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.
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.
We report a 50-year-old man with mediastinal tumor. The patient received the thoracoscopic resection for mediastinal tumor with the operative time of 1 h and intraoperative blood loss of 10 mL. The final diagnosis after surgical excision was an ectopic papillary thyroid carcinoma. The patient recovered well without surgery-related complications, and was discharged on the 2nd day after the operation. No recurrence was found during the follow-up. We also reviewed relevant literature to explore the clinical features, diagnosis, and treatment of ectopic thyroid carcinoma.
ObjectiveTo explore and analyze the related influencing factors for common intraoperative complications during CT-guided percutaneous radiofrequency ablation of pulmonary tumor. MethodsWe retrospectively analyzed the clinical data of the patients who underwent CT-guided percutaneous radiofrequency ablation of pulmonary tumor in our hospital from December 2018 to December 2019, and analyzed the influencing factors for complications. ResultsA total of 106 patients were enrolled. There were 58 (54.7%) males and 48 (45.3%) females aged 46-81 (68.05±8.05) years. All patients successfully completed the operation. The operation time was 47.67±16.47 min, and the hospital stay time was 2.45±1.35 d. The main intraoperative complications were pneumothorax (16.0%, 17/106) and intrapulmonary hemorrhage (22.6%, 24/106). Univariate analysis showed that the number of pleural punctures had an impact on the occurrence of pneumothorax (P=0.00). The length of the puncture path (P=0.00), ablation range (P=0.03) and ablation time (P=0.00) had an impact on the occurrence of intrapulmonary hemorrhage. Multivariate logistic regression analysis showed that the size of the lesion (OR=17.85, 95%CI 3.41-93.28, P=0.00) and the number of pleural punctures (OR=0.02, 95%CI 0.00-0.11, P=0.00) were independent influencing factors for the occurrence of pneumothorax. The length of the puncture path (OR=15.76, 95%CI 5.34-46.57, P=0.00) was the independent influencing factor for the occurrence of intrapulmonary hemorrhage. ConclusionPercutaneous radiofrequency ablation of pulmonary tumor is safe and with a high success rate, but intraoperative complications are affected by many factors, so the surgeons should be proficient in operating skills to avoid complications.

Conclusion In order to avoid the occurrence of adverse reactions, Danshen injection production process should be strictly controlled, and indications should be considered carefully in clinical medication.
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.
ObjectiveTo review the progress of hip fracture treatment in children.MethodsLiterature about the hip fracture treatment in children was extensively reviewed and summarized in terms of anatomy and blood supply, fracture classification, surgical treatment principles, and complications.ResultsThe anatomical structure of children’s hips and the characteristics of peripheral blood supply constantly change with age. Delbet classification is the most classic classification of hip fracture in children. Children’s age and Delbet classification have significant effects on surgical treatment strategies and post-fracture complications. The timing of surgical treatment, accurate anatomical reduction, and appropriate internal fixation can effectively improve the prognosis and reduce the incidence of complications. Common complications include osteonecrosis of the femoral head, coxa vara, premature physeal closure, and nonunion. Conclusion There are still some controversies on the treatment concept and internal fixation choice for children’s hip fracture. So it is necessary to further study the anatomy and blood supply characteristics of children’s hip, improve the selection and application skills of internal fixation devices, so as to avoid serious complications.
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. Two reviewers independently screened literature, extracted data and assessed risk bias of included studies. Statistical analysis was performed using Stata 14.0 software.ResultsA total of 33 randomized controlled trials with 2 855 students were included. The results showed that students in EBM combined with PBL group obtained better scores of specialized theory (WMD=6.87, 95%CI 5.08 to 8.66, P<0.001), skills examination (WMD=10.57, 95%CI 8.98 to 12.16, P<0.001) and case analysis (WMD=9.79, 95%CI 4.71 to 14.88, P<0.001), comparing with those in LBL group. Besides, EBM combined with PBL method improved students’ overall ability including independent learning capability, clinical thinking ability, problem-solving capability, literature exploring capacity, communication and presentation skills and team-work ability.ConclusionsApplication of EBM combined with PBL method can improve clinical teaching quality.
