Objective:To study the effects of enhanced breastfeeding management on the neurodevelopmental outcomes of preterm infants in neonatal intensive care unit (NICU).Methods:From January to December 2020, preterm infants with gestational age (GA) ≥32 weeks admitted to NICU of our hospital were randomly assigned into the enhance group and the control group. Breast-feeding education using WeChat and routinely playing recorded mother's sound to the infants were carried out in the enhance group, while conventional management was carried out in the control group. Breastfeeding status was followed up regularly in both groups. Mental development index (MDI) and psychomotor development index (PDI) at 6-month of corrected GA were measured using Infant Intelligence Development Scale.Results:A total of 109 cases were included in the enhance group and 118 cases in the control group. The breast-feeding rates in the enhance group were significantly higher than the control group at discharge, 3-month and 6-month of corrected GA [88.1% (96/109) vs. 61.0% (72/118), 90.8% (99/109) vs. 67.8% (80/118), 88.1% (96/109) vs. 61.9% (73/118)] ( P<0.05). MDI and PDI at 6-month of corrected GA in the enhance group were significantly higher than the control group [(106.2±10.7) vs. (101.9±11.4), (103.4±13.7) vs. (99.5±11.6)] ( P<0.05). Conclusions:Enhanced breast-feeding management is helpful improving the breast-feeding rate of preterm infants in NICU and beneficial to the neurodevelopment of preterm infants.

The therapeutic efficacy of Danshen and Jiangxiang in the treatment of ischemic stroke (IS) is relatively significant. Studying the mechanism of action of Danshen and Jiangxiang in the treatment of IS can effectively identify candidate traditional Chinese medicines (TCM) with efficacy. However, it is challenging to analyze the effector substances and explain the mechanism of action of Danshen-Jiangxiang from a systematic perspective using traditional pharmacological approaches. In this study, a systematic study was conducted based on the drug-target-symptom-disease association network using complex network theory. On the basis of the association information about Danshen, Jiangxiang and IS, the protein-protein interaction (PPI) network and the "drug pair-pharmacodynamic ingredient-target-IS" network were constructed. The different topological features of the networks were analyzed to identify the core pharmacodynamic ingredients including formononetin in Jiangxiang, cryptotanshinone and tanshinone IIA in Danshen as well as core target proteins such as prostaglandin G/H synthase 2, retinoic acid receptor RXR-alpha, sodium channel protein type 5 subunit alpha, prostaglandin G/H synthase 1 and beta-2 adrenergic receptor. Further, a method for screening IS candidates based on TCM symptoms was proposed to identify key TCM symptoms and syndromes using the "drug pair-TCM symptom-syndrome-IS" network. The results showed that three TCMs, namely Puhuang, Sanleng and Zelan, might be potential therapeutic candidates for IS, which provided a theoretical reference for the development of drugs for the treatment of IS.
