Mature T-cell lymphoid malignancies comprise a group of heterogeneous diseases that vary in clinicopathological features, biological behavior, treatment response, and prognosis. Bone marrow (BM) infiltration is more commonly present in mature T-cell lymphoid malignancies compared with their B-cell counterparts and hence important for differential diagnosis. In this study, clinical characteristics and prognostic factors were analyzed in 225 patients with mature T-cell lymphoid malignancies treated in a single institution. These included 29 cases of T-cell lymphoproliferative disorders (T-LPD, all with BM infiltration) and 196 cases of T-/natural-killer-cell lymphoma (T/NKCL, 56 with BM infiltration and 140 without BM infiltration). The estimated 5-year overall survival (OS) rates of T-LPD and T/NKCL were 96.6% and 37.3%, respectively. T-LPD patients were less likely to exhibit poor performance status, advanced disease stage, presence of B symptoms, or abnormal level of serum β-2 microglobulin. With similar pathological characteristics, T/NKCL patients with BM infiltration showed significantly lower response rates and shorter OS than those without BM infiltration (P = 0.0264 and P<0.0001, respectively). Multivariate analysis indicated that poor performance status, advanced disease stage, elevated serum lactate dehydrogenase level, and BM involvement were independent unfavorable prognostic factors. The Glasgow Prognostic Score may be more efficient than the International Prognostic Index in predicting disease outcome in T/NKCL. In conclusion, clinical characteristics may be useful in more effectively stratifying patients with mature T-cell lymphoid malignancies.

It has been known that, the novel coronavirus, 2019-nCoV, which is considered similar to SARS-CoV and originated from Wuhan (China), invades human cells via the receptor angiotensin converting enzyme II (ACE2). Moreover, lung cells that have ACE2 expression may be the main target cells during 2019-nCoV infection. However, some patients also exhibit non-respiratory symptoms, such as kidney failure, implying that 2019-nCoV could also invade other organs. To construct a risk map of different human organs, we analyzed the single-cell RNA sequencing (scRNA-seq) datasets derived from major human physiological systems, including the respiratory, cardiovascular, digestive, and urinary systems. Through scRNA-seq data analyses, we identified the organs at risk, such as lung, heart, esophagus, kidney, bladder, and ileum, and located specific cell types (i.e., type II alveolar cells (AT2), myocardial cells, proximal tubule cells of the kidney, ileum and esophagus epithelial cells, and bladder urothelial cells), which are vulnerable to 2019-nCoV infection. Based on the findings, we constructed a risk map indicating the vulnerability of different organs to 2019-nCoV infection. This study may provide potential clues for further investigation of the pathogenesis and route of 2019-nCoV infection.

本文报道了采用一种集成了力感应和液体交换功能的微流控芯片来测量单细胞力学性能的方法。使用光学镊子操纵和定位在推力探针和力传感器探针之间的单个细胞。这两个芯片上的探针被设计用来捕获和使细胞变形。通过移动由外力驱动的推力探针,而使单个细胞变形。层流在探针之间形成液-液界面以改变细胞外环境。通过控制注入压力来改变界面的位置。通过调整两个正压力和一个负压力来平衡流动的扩散和扰动。在微流控芯片中测定了不同渗透浓度环境下的单个集胞藻(Synechocystis)菌株PCC 6803 的力学性能。在0.3~0.7 s 内实现液体交换过程,同时也显示了单个细胞的动态变形。可以在30 s 内收集不同渗透浓度下两个杨氏模量值的测量结果以及单个细胞在渗透压冲击下的动态响应。研究了野生型(WT)和突变型集胞藻细胞的动态变形,揭示了机械敏感(MS)通道的功能机制。该系统提供了一种监测单个完整细胞响应快速外部渗透变化的实时力学动力学的新方法;因此,该系统为准确描述细胞中MS通道的生理功能提供了新的机会。

据预测2030年我国人口将会达到峰值14.5亿,城市化率达到70 %,届时城市人口新增3亿,总数将超过10亿。随着总人口的持续增加以及城市人口的迅速膨胀,我国未来将会面临严峻的粮食不足问题,尤其以蛋白质为代表的营养物质将会出现严重短缺。本文针对这一问题,提出了以风力发电为能源,以煤制天然气为原料的单细胞蛋白制备新思路,新途径。此方法通过煤制天然气生产单细胞蛋白,既解决了传统煤炭利用中碳排放高、环境负荷大等缺点,实现了煤炭的升级、绿色利用,又解决了利用石油、工农业废弃物生产单细胞蛋白所产生的食品安全性等问题。另外,此方法可实现大规模工业化生产,为解决我国未来蛋白质不足提供一条绿色、高效、切实可行的新途径。

方法学创新一直是微生物组学研究的核心驱动力。我们认为在未来五到十年,微生物组的方法学体系在研究理念与技术平台方面将发生三大变革:①从监测菌群“结构”变化向监测菌群“功能/状态”变化的变革;②从细胞“群体”分析精度向细胞“个体”分析精度的转变;③从“数据分析”向“数据科学”的跨越。在这里我们针对实现上述三大方法学变革需要克服的关键科学或技术挑战,重点介绍了部分中国微生物组分析方法学研究团队及其国际合作伙伴的最新工作进展。我们相信中国微生物组计划应把握住当前这一重要机遇,通过在微生物组分析方法学前沿开展富有雄心、远见、创意与竞争力的交叉合作研究,为国际微生物组计划贡献一系列“中国制造”的新方法、新工具和新仪器。
