    This paper proposed an improved greedy strategy suitable for robot sorting path planning to solve the problem of the traditional sequential path planning algorithm being inefficient. For the small robotic arm system， the logistics palletizing system was comprehensively reconstructed，and the sorting path of the logistics palletizing was planned by the greedy algorithm，significantly reducing the path completion time. Considering that the greedy algorithm may fall into the local optimal situation in the path planning process， this paper designed a probability density function to improve the greedy algorithm and enhance the practicability of the algorithm. The feasibility of the algorithm was verified by building the palletizing robot. The experiment results showed that the improved greedy sorting path algorithm was significantly lower than the traditional sequential scheduling algorithm in terms of total time，and the operating efficiency of the robotic arm increased by 20% - 28% on average，which verified the effectiveness of the improved greedy algorithm in palletizing and sorting path planning.

    Bisphenols（BPs）are the most common environmental endocrine disruptors，and their concentration is still increasing in the environment. Through the digestive system， respiratory system，and dermal contact，BPs enter the human body and then induce negative health effects. Breast cancer is the most common malignant tumor in women worldwide. Epidemiological and clinical data suggest that hormones，as well as endocrine disruptors， play important roles in the development and progression of breast cancer. Long- time lowdose exposure to bisphenols also promotes the development and metastasis of breast cancer. This paper described the research progress and the underlying mechanisms of BPs on promoting breast cancer metastasis，providing new thoughts on understanding breast cancer metastasis from the perspective of environmental pollutants.

    According to the research results of the influence of low- temperature stress on the growth and development of plant roots in recent years， this paper systematically elaborated the response mechanism of plant roots to low- temperature stress from the aspects of root morphology， physiological and molecular mechanisms， and root-soil environment. In addition，the regulation measures to improve the ability of plant roots to resist low temperatures were summarized from the aspects of variety，water and fertilizer operation，exogenous chemical control preparations，and microbial agents. It was suggested that phenomics （near-infrared imaging，X-ray，CT imaging，etc.） should be used to strengthen the study of the morphological structure and growth process of plant roots under low- temperature stress in the future. By combining root physiology and ecology with modern molecular biology technologies（proteome，transcriptome，metabolome，etc.），the root response mechanism in plant resistance to low temperatures should be deeply explored， and the research on root and ground interaction should be strengthened to provide a reference for a more systematic and in-depth study on the cold resistance mechanism of plant roots.
