Background: For Stage II/III rectal cancer patients, curative resection is the primary treatment, prescribing of postoperative adjuvant chemotherapy (PAC) is regarded as a standard therapy. The interval between surgery and the initiation of PAC is usually within 8 weeks. However, the optimal cut-off is still controversial. This study aimed to explore the impact of extremely early initiation of PAC for II/III rectal cancer. Methods: Patients with Stage II/III rectal cancer treated from January 2013 to December 2015 were retrospectively collected at the Department of Tongji Hospital. According to the starting point of PAC, patients were categorized into two groups: extremely early group (The interval of PAC ≤ 2 weeks) and normal group (The interval of PAC within 3 - 5 weeks). For the sake of evaluating the effectiveness of different intervals, Overall Survival rate (OS), Progress-Free Survival rate (PFS) and Recurrence or Metastasis Rate (RMR) were analyzed, as well as the Quality of Life Score. To estimate the safety of the extremely early PAC, we evaluated the first post chemotherapy adverse reactions and defecation ability, and analyzed the variance laboratory indexes around the first postoperative adjuvant chemotherapy. Results: A total of 267 patients were included in this study. Compared to normal group (192 cases), extremely early group (75 cases) of patients attained a better tendency of OS and PFS, although there were no significant statistical differences (OS: P = 0.0930;PFS: P = 0.1058). However, the RMR was significant lower (P = 0.0452) and the Quality of Life Score was significantly higher (P = 0.0090) in extremely early group. Multivariate analysis also showed that extremely early group had better defecation ability (P = 0.0149) and less side reactions of post chemotherapy, such as vomiting (P , got a higher level of inflammatory cells (P Conclusion: For Stage II/III rectal cancer patients, extremely early to start PAC not only might be effectively prol

针对服役期满航天器再入近空间飞行环境多次解体绕流问题,发展了求解高超声速来流条件下含振动能激发热力学非平衡Navier-Stokes(N-S)方程三维双体解体物绕流问题的数值方法.根据解体物运动分离特点与方位关系,确立了两种不同的解体物双体构型.经高超声速氮气流绕圆柱、钝体计算结果与求解Boltzmann模型方程气体动理论统一算法、风洞试验等比较确认,验证了本文模型算法在求解近空间范围内含振动能激发的多体高超声速绕流问题的可行性和准确性.采用此算法研究了近空间范围内不同飞行攻角、不同间隔比下的双体构型间的气动干扰效应.结果表明,本文所设工况下,当间隔比大于一定值时,解体物之间的相互干扰效应可以忽略.这为气动融合弹道飞行航迹落区数值预报软件研制提供理论设计准则及大量近空间非规则解体物绕流气动干扰数据库.

Sulfur dioxide （SO2） gas is one of the major pollution in the atmosphere whose content is an important air quality indicator assessed by environmental monitor stations. In this paper, an ultraviolet LED is applied as light source whose centre wavelength is 300nm. Having got through the sample cell, the light is divided into the reference light and sample light with different SO2 concentration by the spectroscope. The light intensity modulation factor can be calculated by measuring the difference of spectral intensity of the two lights, thus the SO2 gas concentration is rated. The concentration calibration curve with very high linearity can be obtained by means of measuring several groups of SO2 with different concentration. This study shows that the measurement method can be applied in the measurement of SO2 concentration with low cost, anti- interference and high sensitivity.

租界化的上海是30年代左翼文学思潮的滋生地,左翼文学思潮的兴起与租界文化气候有密切关系。租界化的上海具有左翼文学思潮所必需的社会阶级构成模式和政治语境,租界的文化风尚和商人的投资,对左翼文学思潮的风行起到了推波助澜的作用,左翼文学思潮符合大部分租界作家的精神状态和租界人的文化心理。租界的文化语境,对于左翼文学现象来说,是一种“失之东隅收之桑榆”的历史安排。
