In order to find out a new pathway for utilizing heterosis of Zinnia elegans and accelerate breeding process, the mechanism of anther development of a male sterile line was explored. Backcross, sibmating, selling of fertile plants and testcross with inbred lines were analyzed and identified in the field, and cytology was observed. Recessive nucleus male sterile line AH209AB capable of being a maintainer was obtained by successive backcrosses with male sterile plants and fertile F1 plants as male parents. Cytological and anatomical studies indicated that：（1） The wall of normal anther was constituted of four layers of cells such as epidermis, powder chamber wall, middle level and tapetum cells. The process in meiosis of pollen mother cell in Zinnia elegans was normal and cytoplasm divided simultanously. Mature pollen grain was tricellular type. （2） The petal of male sterile plant degraded as a thread-like structure, the stamens were villiform in appearance and no pollens were formed. The result showed that the anther of male sterile plant no longer proceed to differentiate spore mother cell and the pollen sac after the formation of the tissue of sporogenous cells, there was no evident boundary between tapetum cell, middle lamella and inner wall of PMC, tapetal cells did not develop from the very beginning. So the abortion type was completely structural male sterility. The male sterile line belongs to non-sporange male sterile type and is of great use in F1 seeds production.

Mammalian target of rapamycin(m TOR) inhibitor as an attractive drug target with promising antitumor effects has been widely investigated. High quality clinical trial has been conducted in liver transplant(LT) recipients in Western countries. However, the pertinent studies in Eastern world are paucity. Therefore, we designed a clinical trial to test whether sirolimus can improve recurrence-free survival(RFS) in hepatocellular carcinoma(HCC) patients beyond the Milan criteria after LT. This is an open-labeled, single-arm, prospective, multicenter, and real-world study aiming to evaluate the clinical outcomes of early switch to sirolimus-based regimens in HCC patients after LT. Patients with a histologically proven HCC and beyond the Milan criteria will be enrolled. The initial immunosuppressant regimens are center-specifc for the frst 4-6 weeks. The following regimens integrated sirolimus into the regimens as a combination therapy with reduced calcineurin inhibitors based on the condition of patients and centers. The study is planned for 4 years in total with a 2-year enrollment period and a 2-year follow-up. We predict that sirolimus conversion regimen will provide survival benefts for patients particular in the key indicator RFS as well as better quality of life. If the trial is conducted successfully, we will have a continued monitoring over a longer follow-up time to estimate indicator of overall survival. We hope that the outcome will provide better evidence for clinical decision-making and revising treatment guidelines based on Chinese population data.

目的了解我国住院极早产儿(very preterm infant,VPI)宫外生长迟缓(extrauterine growth restriction,EUGR)的发生率及影响因素。方法采用多中心前瞻性调查研究方法,纳入2019年9月至2020年12月我国7个地区28家医院新生儿科的2514例VPI临床资料,根据纠正胎龄36周或出院时的体重评估是否发生EUGR,分成EUGR组(n=1189)和非EUGR组(n=1325)。比较两组VPI的临床特征,探讨EUGR的发生情况及相关因素。结果以体重评价,EUGR的发生率为47.30%(1189/2514)。多因素logistic结果显示,恢复出生体重后平均体重增长速率快和住院第1周累计热卡高是EUGR的保护因素(P<0.05),小于胎龄儿、达全肠内营养所需时间长、累计禁食时间长、开始添加母乳强化剂时的母乳量少及达到全强化的所需时间长、中-重度支气管肺发育不良是EUGR发生的危险因素(P<0.05)。结论尽早达全肠内营养,及时强化母乳喂养,增加生后第1周的热卡摄入,提高体重增长速率,以及防治中-重度支气管肺发育不良对降低VPI EUGR的发生率至关重要。
