视网膜静脉阻塞(RVO)是最常见的致盲性视网膜血管疾病之一,常继发黄斑水肿(ME),从而造成患者严重的视功能损害。RVO继发ME(RVO-ME)视网膜和脉络膜改变中的光相干断层扫描生物学标志物在RVO-ME患者的病情评估、疗效评价、视力预测等方面有重要的临床价值,其中视网膜内层结构紊乱、外界膜和椭圆体带的完整性、黄斑中心凹视网膜厚度改变是评价视力预后的可靠指标;强反射点、视网膜下液和视网膜内液可作为反映炎症水平的重要参数;中界膜征和急性黄斑旁中心中层视网膜病变是判断视网膜缺血程度的客观依据;脉络膜血管指数和脉络膜厚度变化也在评估病情进展方面存在潜在的优势。准确地把握RVO-ME相关光相干断层生物学标志物的特点,有利于其在RVO-ME临床诊断和治疗中的合理、精准运用,并有助于进一步深入探究该疾病的发病机制。

针对现有马铃薯收获机摆动筛式薯土分离筛装置破皮率和分离输送效率两者难以平衡的问题,对马铃薯输送分离作业进行了室内试验,确定了影响马铃薯破皮率和分离输送效率的主要作业参数。以马铃薯在摆动分离筛上的最大跳跃高度和分离时间为指标进行室内单因素试验和正交试验。单因素试验表明:马铃薯在摆动分离筛上最大跳跃高度与马铃薯质量、曲柄转速呈正相关,与筛杆间距、筛面倾角呈负相关;分离时间与筛杆间距呈正相关,与马铃薯质量、曲柄转速、筛面倾角呈负相关;筛杆材料65Mn-橡胶表现较好。正交试验表明:影响马铃薯最大跳跃高度的主次顺序为筛杆材料>筛杆间距>筛面倾角>曲柄转速;影响马铃薯分离时间的主次顺序为筛面倾角>筛杆间距>曲柄转速>筛杆材料;较优的分离筛参数组合为曲柄转速200r/min、筛面倾角21.7°、筛杆材料65Mn-橡胶、筛杆间距50mm。得到的试验数据和结论可为马铃薯输送分离装置的结构改进和参数优化提供参考。

In our study, we determined the efficacy of bortezomib-based induction therapy followed by autologous stem cell transplant （ASCT） in newly diagnosed and relapsed/refractory （R/R） multiple myeloma （MM） patients and compared the advantages of early versus late transplant. We used a retrospective analysis to examine 62 patients, including 46 cases of newly diagnosed MM （early transplant group） and 16 cases of relapsed/refractory MM （late transplant group）. All of these patients received bortezomib-based induction therapy followed by ASCT. The efficacy and side effects of the treatment regimen were analyzed. Patients＇ overall survival （OS） and progression-free survival （PFS） times were determined. The ratio of complete remission to near-complete remission （CR/nCR） was 69.5% versus 56.2% （P=0.361）, respectively, for the early transplant group versus the late transplant group, respectively, after receiving bortezomib-based induction therapy; the overall response rates of the two group were 91.3 % and 81.2 %, respectively （P=0.369）. After receiving ASCT, the CR/nCR of the two groups increased to 84.8% and 81.3%, respectively. The median time required for neutrophil engraftment of the early transplant group and the late transplant group was 11 and 14.5 days, respectively （P=0.003）; the median time required for platelet engra^nent was 13 and 21.5 days （P=0.031）, respectively. There were no significant differences in the toxic side effects observed during induction therapy and ASCT between the two groups. The OS of the two groups was not statistically different （P=0.058）. The PFS of the early transplant group and the late transplant group was 41.6 and 26.5 months, respectively （P=0.008）. Multivariate analysis demonstrated that the time of receiving ASCT, the types of M protein, and the International Staging System （ISS） stage were all independent factors that influenced PFS. In conclusion, patients in a suitable condition for ASCT should be recommended to have an early ASCT i

生态环境部发布的HJ 1082—2019《土壤和沉积物六价铬的测定碱溶液提取-火焰原子吸收分光光度法》于2020年6月正式实施,是目前国内唯一的法定土壤和沉积物Cr(Ⅵ)测定方法。然而现有研究发现,修复后的Cr(Ⅵ)污染土壤测定结果存在假阳性或负偏差的问题。针对其中与溶解性Cr(Ⅲ)、淋洗剂(柠檬酸盐)和还原剂(FeSO_(4)、Na_(2)S_(2)O_(5)、Na_(2)S和CaS_(x))相关的问题进行研究,结果表明:修复过程中产生的Cr(Ⅲ)在整个修复和检测过程中均处于过饱和状态,导致检测结果出现较小正偏差,存在误判风险。土壤对Cr(Ⅲ)的吸附作用对降低检测正偏差至测定下限以下起着至关重要的作用。柠檬酸盐能显著促进Cr(Ⅲ)溶解,可能导致正偏差。修复后土壤中残留的大量还原剂会在碱消解或pH调节过程中将提取的Cr(Ⅵ)还原为Cr(Ⅲ),导致显著的负偏差。火焰原子吸收分光光度法(FAAS)检测的正偏差程度较小且存在较大不确定性,不能抵消残留还原剂产生的负偏差。
