As emerging means of cancer treatment, immunotherapy is the fourth major therapeutic strategy after surgery, chemoradiotherapy, and targeted therapy, which benefits patients a lot. It has been more than 100 years for the medical community exploring how to harness the immune system to fight cancer. Since the advent of ipilimumab in 2011, the first checkpoint inhibitor, cancer immunotherapy represented by checkpoint inhibitors has exploded. Several programmed death protein-1 and programmed cell death ligand-1 inhibitors have successively been approved to treat advanced non-small cell lung cancer in the second-line setting or even the first-line setting. But checkpoint inhibitors therapy has only achieved limited benefit at the present stage. Exploring potential predictive biomarkers and mechanisms of resistance are in need of further consideration to optimize immunotherapy.
Severe acute kidney injury usually requires renal replacement therapy. Intermittent hemodialysis, peritoneal dialysis, continuous renal replacement therapy, and prolonged intermittent renal replacement therapy are the four common modalities of renal replacement therapy. Whether one modality of renal replacement therapy is superior to another in clinical practice remains controversial. The impact of the choice of renal replacement therapy modality on the short-term and long-term prognosis of patients needs to be further explored in large-scale randomized controlled studies and a longer follow-up time. This article will discuss the development history of renal replacement therapy for acute kidney injury, the current status of its application, and the comparison of the four treatment modalities, in order to help clinicians have a deeper understanding of how to design individualized renal replacement therapy programs for patients with acute kidney injury under the guidance of the concept of precision medicine.

目的 比较经尿道前列腺剜除术（TUEP）与经尿道前列腺电切术（TURP）的疗效。 方法 2010年11月－2011年3月，收治前列腺增生（BPH）患者58例，分别采用TUEP（30例）、TURP（28例）治疗。患者年龄55～87岁，平均73岁；病程1～12年，平均5年。术前常规行直肠指检前列腺光滑无结节；经直肠前列腺彩色超声多普勒检查，测得前列腺体积为50～80 mL，平均62 mL；血清前列腺特异性抗原＜10 ng/mL。 结果 TUEP组术中出血量、术后冲洗时间均短于TURP，切除前列腺组织体积大于TURP组，差异均有统计学意义（P＜0.05）。术后拔除尿管后发生暂时性尿失禁TUEP组1例，TURP组发生2例，两组比较差异无统计学意义；两组均无永久性尿失禁发生。 结论 TUEP与TURP相比较，TUEP手术疗效好，出血少、恢复快，且并发症少。
Objective To investigate the application status of titrated oxygen therapy in patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD) by means of literature retrieving. Methods Database retrieving is taken on eight major domestic medical journals about the treatment for AECOPD patients during the period of January 2013 to December 2015. Results There were 70 articles involving the treatment of AECOPD in the eight major journals during 2013 to 2015. Oxygen therapy was not mentioned in 14 articles, oxygen therapy data were incomplete in 13 papers and relatively complete in 43 papers. None of the articals provided full description of oxygen therapy. The arterial blood gas of the patients was analyzed, and showed excessive or not enough on effect of oxygen treatment. Conclusion The clinicians did not pay enough attention to oxygen treatment for AECOPD patients, so treatment guideline and clinical pathway should be construed to standardize titrated oxygen therapy.

Waldenström macroglobulinemia (WM) is a rare indolent lymphoplasmacytic lymphoma. Bruton’s tyrosine kinase (BTK) plays a key role in the signaling pathway of WM, which has changed the way of treatment of WM. As a first-generation BTK inhibitor, ibrutinib is an early-stage treatment and a salvage treatment that can control toxicity characteristics. However, in order to overcome the resistance of the first-generation BTK inhibitors, reduce the adverse reactions caused by off-target effects, and improve the efficacy, the research and development of new BTK inhibitors has become a hot topic. This article discusses the clinical studies of the first generation and new BTK inhibitors for WM, aiming to provide a certain basis for the more rational application of BTK inhibitors in WM.
Objective To determine if the therapeutic response to an inhaled corticosteroid is attenuated in individuals with asthma who smoke.Methods 38 outpatients with chronic stable asthma who visited during March 2008 and January 2009 were enrolled in the study. 23 cases were nonsmokers and 15 cases were smokers. All of them were treated by daily inhaled budesonide, and β2 agonist when necessary.They were required to record symptoms and peak expiratory flow every day on an asthmatic diary card. Thepatients were followed 28 days. ACT score, asthma-symptom score, Asthma Control Test ( ACT) score,pulmonary function, and peak expiratory flow were compared between the non-smoking and the smoking asthmatic patients. Results All of the patients had statistically significant increases in ACT score, mean morning and night PEF, mean forced expiratory volume in 1 second, and a significant decrease in asthmasymptom score after budesonide treatment compared with before. There were significantly greater changes inany of these parameters in the non-smokers than in the smokers. Conclusions Active cigarette smoking impairs the efficacy of short term inhaled corticosteroid treatment in asthma. This finding has important implications for the management of patients with asthma who smoke.
Objective To investigate and compare the difference between two implants of reconstructing anterior cruciate l igament (ACL) for the early heal ing of implants tunnel interface in terms of biological mechanism. Methods Fiftyfive adult New Zealand rabbits weighing 2.0-2.8 kg were selected. Patellar l igament with tibia-bone block was obtained fromthe left knee joint serving as donor site, right knee joint served as the recipient site of autograft for ACL reconstruction. Thebone block end of implant was bone-bone interface heal ing model, while the l igament end was tendon-bone interface heal ing model. The general condition of rabbits was observed after operation, the gross observation and histology observation were conducted at 2, 4 and 8 weeks after operation (n=5), and biomechanics examination was conducted at 4 and 8 weeks after operation (n=20). Results Rabbits behaved normally after operation. The gross observation indicated that ACL had complete continuity and moderate tension during experiment. Histology observation: most part of bone-bone interface was connected by fibrous tissue, while the tendon-bone interface was mainly filled by granulation tissue 2 weeks after operation; most part of bone-bone interface was bone union, and there were osteogenesis reaction and large quantity of fibroblasts in the tendonbone interface 4 weeks after operation; complete bone union was evident in bone-bone interface, and the appearance of Sharpey fibers and the formation of indirect insertion occured in part of tendon-bone interface 8 weeks after operation. Biomechanics observation: the pull-out rate for tendon-bone interface and bone-bone interface 4 weeks after operation was 85% and 15%, respectively; while it was 95% and 5% 8 weeks after operation, respectively; indicating there was a significant difference between two groups (P lt; 0.001). Conclusion In the early stage after ACL reconstruction, bone-bone interface is better than tendonbone interface in terms of intensity and speed of heal ing.
Objective To investigate the surgical effect on different types of spinal canal stenosis of retrograde degeneration. Methods The retrospective analysis was performed on 96 patients (85 males, 11 females; average age 54, range 39-71) admitted from September 2001 to January 2004 for spinal canal stenosis of retrograde degeneration. The patients were divided into five groups according to their clinical symptoms and signs and the imaging of the spinal cord. In group A, 39 patients had one segment of the spinal canal stenosis and they underwent the recessively expanding operation through the intervertebral canal by opening a window between the vertebral plates. In group B,21 patients had stenosis of the central vertebral canal of one segment and theyunderwent excision of the intervertebral disc through the window opened betweenthe vertebral plates and the recessively expanding operation.In group C, 18 patients had degenerative spinal derangement of one segment and they underwent decompression through the window opened between the bilateral vertebral plates and the recessively expanding operation, and then underwent the internal fixation and bone grafting. In group D, 11 patients had the mixed stenosis of the vertebralcanal of more than 2 segments and they underwent the recessively expanding operation through the window opened bilaterally on the diseased segment and excisionof the yellow ligament and the intervertebral disc. In group E, 7 patients had degenerative lateral curvature of the spine and they underwent the combined surgical procedures including decompression, internal fixation, and bone grafting. All the patients were followed up after operation. Results The follow-up of the 96 patients for 6-36 months with an average of 12.2 months showed that they had no postoperative complications. According to the JOA Scoring,85 patients had an excellent result, 9 had a good result, 1 had a fair result, and only 1 had a poor result. The X-ray films revealed no mistaken placing of the nails on the vertebral arch, broken nails or loosened nails. Conclusion The limited surgery and effective decompression can improve curative effects and reduce complications of spinal canal stenosis of retrograde degeneration. The imaging of the spinal cord has an important value in the choice of surgical protocols for spinal canal stenosis of retrograde.
