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.
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.

Methods We retrospectively analyzed the clinical records of 82 patients with adverse reaction to intravenous infusion of Danshen injection from January 2007 to December 2010. Results Adverse reaction incidence was higher in males than females, and it mainly occurred in patients of middle or old ages. Most of the adverse reactions happened within 30 minutes of the infusion. Type-I allergic reaction was more commonly observed. 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 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.
目的 探讨不同诊断或分类标准在脊柱关节病患者之间诊断效能、临床特点。 方法 收集2000年2月－2012年8月141例脊柱关节病患者及197例类风湿关节炎、未分化关节炎患者资料。采用3种诊断标准下对141例患者分为纽约标准（NY）组、欧洲脊柱关节病研究（ESSG）组及脊柱关节病国际评估（ASAS）组，统计患者的临床表现、骶髂关节CT、MRI、实验室指标，并加入197例类风湿关节炎未分化关节炎患者，计算和比较3种诊断的敏感性、特异性。 结果 在141例脊柱关节病中，62例符合NY标准，34例符合ESSG标准，45例只符合ASAS标准。3组患者在性别、胸廓受限、附着点炎及跖（指）炎、非甾体抗炎药及慢作用药使用、炎症因子水平方面差异无统计学意义（P＞0.05）；ASAS组则较19 NY组及ESSG组患者更年轻、病程较短，且表现有外周关节炎明显高于其余两组（P＜0.05）；NY组炎性腰背痛、脊柱活动受限、HLA-B27阳性率明显高于其余两组，且使用生物制剂比例最高，达48.38；在骨盆X线、骶髂关节CT表现关节侵蚀上，NY组较其他两组更严重。NY、ESSG、ASAS分类标准敏感性依次为43.97%、47.51%、73.76%，特异性依次为100.00%、90.86%、84.26%。 结论 ASAS分类标准敏感性高，患者更年轻、病程更短，炎性腰背痛、外周关节炎是ASAS诊断中非常重要的指标；NY组脊柱活动受限及关节侵蚀最显著，HLA-B27阳性可能是预测AS很好的指标。NY标准特异性最高，敏感性最低，而ASAS标准敏感性最高，特异性最低。

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.
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 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.
