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.
The 12th Asian Conference on Pharmacoepidemiology (ACPE) has been successfully held from October 11st to 13rd, 2019 in Kyoto, Japan. More than 600 representatives from 33 countries and regions participated in the meeting. The arrangement of this conference mainly included: education session program, contributed papers report, symposium and poster presentation, which provided good opportunity for participants to communicate. Moreover, it promoted the dissemination and utilization of advanced methods and technologies of global pharmacoepidemiology, especially in Asia region, and provided technical support in order to ensure the safety and efficacy of public. Moreover, it was the first time that the symposium on herbal and Traditional Medicines has been set up in the ACPE. This paper introduced the main details of the contents
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。
目的:探讨B超监测下输尿管镜治疗输尿管结石的临床疗效及可行性。方法:2007年12月~2008年12月采用B超监测下输尿管镜治疗输尿管结石患者34例,结石位于上段4例,中段11例,下段19例。结果:一次性碎石治愈者33例,一次性碎石成功率97%,手术时间(40±15)min,术后2~7天排尽结石,术后住院平均时间3.5(2～5)天。结论:B超监测下输尿管镜治疗输尿管结石对于手术操作者易于随时动态观察结石情况,对于大于0.4 cm的碎石块无遗漏,增加术中一次碎石成功率,可行性高。
Suture broken, knot slipping and tissue tearing are the main reasons of wound closure failure in clinical operation. Based on this, we simulated the suturing and healing operation by using a biological materials testing machine and investigated the tensile properties before and after knotting, relaxation property and friction property of three common sutures: silk, polyglactin 910 and polypropylene. Results show that the tensile property decreased after knotting. The tensile strength of polyglactin 910 and elongation of polypropylene were the largest. During the relaxation process, the sutures relaxed the most in the first 2 hours. The relaxation from less to more was: polyglactin 910, silk and polypropylene. Coating or monofilament could obviously reduce the surface roughness of sutures, and thus reduce the friction force of the suture-suture interface. The friction force of the suture-suture interface increased with the increasing load but did no change with the increasing velocity. The results can provide an important theoretical basis for the optimizations of suture design and knotting operation.
目的：讨论剖宫产瘢痕妊娠的早期正确诊断方法和适当的治疗措施。方法：回顾性分析我院35例剖宫产瘢痕妊娠病例的临床表现、超声影像和治疗方法。结果：33例病例经血βhCG测定、B超或彩超确诊，2例行清宫术或诊刮术时发生大出血，后经彩超修正诊断。31例接受药物、清宫等保守性治疗，4例接受介入治疗，所有病例均好转或痊愈。结论：广大临床医师对剖宫产瘢痕妊娠认识的提高，以及超声检查技术的发展，使早期明确诊断和成功保守治疗该病成为可能。
