早期高危子宫内膜癌“夹心模式”序贯放化疗的疗效分析

目的评估“化疗-放疗-化疗”的“夹心模式”序贯放化疗在早期高危子宫内膜癌患者中疗效及可行性。方法回顾性分析2004年1月至2015年12月于北京大学人民医院行分期手术,分期(FIGO 2009)Ⅰ~Ⅱ期,且术后行“夹心疗法”的内膜癌患者,分析其临床病理特征,复发、生存及副反应。结果40例纳入研究,平均年龄(57±7)岁;随访51~182个月,仅1例术后66个月发生远处复发,其余均无瘤生存;5年总生存率及无疾病生存率均100%;无疾病生存期(178.7±3.3)m(95%CI:172.3~185.1);16例出现化疗副反应,仅1例发生Ⅲ度骨髓抑制;8例出现放疗副反应,其中1例发生左侧输尿管狭窄,其余为Ⅰ~Ⅱ度副反应。结论“夹心疗法”应用于早期高危内膜癌具有较好疗效,副反应可耐受。因病例数有限,有待积累病例,进一步总结。

淡豆豉的发酵工艺沿革及过程控制概述

通过查阅古籍及现代文献，对淡豆豉的历史演变、古今发酵工艺对比和关键环节控制进行了系统的梳理，分析并总结了淡豆豉的品质影响因素及其控制方法，以期为淡豆豉质量控制研究提供参考依据。经分析后发现，在淡豆豉的发酵过程中，发酵菌种、杂菌、温度和湿度等均为影响其品质的重要因素，“后酵”过程的条件控制更是被历代本草重点关注。此外，古代认可的“香美之豉”是以霉菌为优势菌发酵而成，发酵霉菌的选育和使用应是解决淡豆豉品质问题的要点。因此，基于历代本草所载 “香”和“美”的评价指标深入研究和优化菌种、温度、湿度等工艺条件对提高淡豆豉的品质具有重要意义。

Z形皮瓣及推进皮瓣修复眼睑缺损的作用探讨

目的探讨眼睑恶性肿瘤切除术中应用Z形皮瓣及推进皮瓣I期修复眼睑缺损的临床效果。方法将50例眼睑恶性肿瘤切除术患者按不同缝合方法分为两组,即对照组25例,术中直接缝合;观察组25例,术中行Z形皮瓣及推进皮瓣I期修复;比较两组眼睑修复效果。结果观察组术后皮瓣成活率96.0%、切口Ⅰ期愈合率100%、修复满意率92.0%,均高于对照组的72.0%、68.0%、56.0%,差异有统计学意义(P<0.05)。观察组术后并发症发生率低于对照组,但差异无统计学意义(P>0.05)。结论眼睑恶性肿瘤切除术中眼睑缺损修复时,采用Z形皮瓣及推进皮瓣,眼睑修复良好,患者修复满意率高,值得推广应用。     

Oncologic outcomes of pathologic T4 and T3 colon cancer patients diagnosed with clinical T4 stage disease using preoperative computed tomography scan

BackgroundThe diagnostic accuracy of computed tomography (CT) for colon cancer is low, and the preoperative risk factors for locally advanced colon cancer are unknown. This study aimed to evaluate the correlation between preoperative CT scan findings and oncologic outcomes and to identify risk factors associated with locally advanced colon cancer.Materials and methodsPatients diagnosed with clinical stage (cT) 4 colon cancer based on preoperative CT scan findings who underwent curative surgery between January 2005 and December 2015 were retrospectively studied. Patients were divided according to pathologic stage (pT) into pT3 (n = 114) and pT4 (n = 102).ResultsThe disease-free survival rate was significantly different between the pT3 and pT4 groups (88.6% vs. 68.6%, p < 0.001). The overall survival rate of the pT3 group was significantly higher than that of the pT4 group (91.2% vs. 76.5%, p = 0.002). Perineural invasion and tumor budding were identified as preoperative risk factors predisposing to pT4 staging (p = 0.044, p = 0.001).ConclusionThe survival rate of pT3 patients was significantly higher than that of pT4 patients with a preoperative cT4 diagnosis. This suggests that when planning for neoadjuvant chemotherapy in locally advanced colon cancer, preoperative CT scan findings may overestimate clinical staging and lead to inappropriate treatment. Thus, there is a need for a new modality to evaluate local advancement in colon cancer.     

Development of vaccines for Plasmodium vivax malaria

Plasmodium vivax continues to cause significant morbidity outside Africa with more than 50% of malaria cases in many parts of South and South-east Asia, Pacific islands, Central and South America being attributed to P. vivax infections. The unique biology of P. vivax, including its ability to form latent hypnozoites that emerge months to years later to cause blood stage infections, early appearance of gametocytes before clinical symptoms are apparent and a shorter development cycle in the vector makes elimination of P. vivax using standard control tools difficult. The availability of an effective vaccine that provides protection and prevents transmission would be a valuable tool in efforts to eliminate P. vivax. Here, we review the latest developments related to P. vivax malaria vaccines and discuss the challenges as well as directions toward the goal of developing highly efficacious vaccines against P. vivax malaria.
