为开发高效、绿色、低成本的脂肪酶应用于结构脂质的制备，从内源性（脂肪酶的来源、基因序列、空间位阻）和外源性(底物空间结构、反应介质、固定化条件及反应pH)两方面讨论了脂肪酶位置选择性的影响因素。脂肪酶催化特异性由内源性因素和外源性因素共同决定。改变底物空间结构、反应介质、固定化条件和反应pH，常被用作提高脂肪酶催化性能的处理方式。只有充分考虑内外两方面因素的影响，才能充分提高脂肪酶的位置选择性和催化效率。该综述有望为高选择性脂肪酶的开发开辟新的研究方向，为后续结构脂质的高效合成提供启发性的研究思路。 To develop efficient, green and low-cost lipases for the preparation of structured lipid, the factors affecting lipase regioselectivity were discussed in terms of both endogenous (source of lipase, gene sequence, spatial resistance) and exogenous (substrate spatial structure, reaction medium, immobilization conditions and reaction pH). The lipases catalytic specificity were determined by the endogenous and exogenous factors, and changing the substrate spatial structure, reaction medium, immobilization conditions and reaction pH, were often used as treatment ways to improve the catalytic performance of the lipase. Only by fully considering the effects of both internal and external factors, the regioselectivity and catalytic efficiency could be improved. The summarize is expected to develop new research directions for the development of highly selective lipase and provide enlightening research ideas for the subsequent efficient synthesis of structured lipid.

目的 分析压力性损伤智能化“评估-决策-控制”系统在脑血管病重症患者中的应用效果。 方法 对压力性损伤管理系统进行智能优化，将系统优化前（2018年1月-2019年12月）应用患者（2448例）设置为对照组，系统优化后（2020年1月-2021年12月）应用患者（3547例）设置为观察组，比较两组患者入科2 h内压力性损伤评估完成率、风险评估准确率、伤口评估准确率、伤口处理正确率、院内压力性损伤发生率的差异。 结果 对照组和观察组患者入科2 h内压力性损伤风险评估完成率分别为94.7%和99.0%（χ2=7.3，P=0.007），风险评估准确率分别为89.0%和96.3%（χ2=11.9，P=0.001），伤口评估准确率分别为74.0%和90.0%（χ2=4.3，P=0.037），伤口处理正确率分别为84.0%和96.0%（χ2=4.0，P=0.046），差异均有统计学意义。对照组院内压力性损伤发生率为0.04％（1/2448），观察组院内压力性损伤发生率为0（0/3547）。 结论 压力性损伤智能化“评估-决策-控制”系统，可以帮助护士准确评估、判断和记录压力性损伤，并做出合理的临床护理决策。 Abstract: Objective To analyze the application effect of pressure injury intelligent "assessment-decision-control" system in severe patients with cerebrovascular disease. Methods The pressure injury management system was optimized, and the severe cerebrovascular disease patients (2448 cases) before system optimization (January 2018-December 2019) were selected as the control group, and the severe cerebrovascular disease patients (3547 cases) after system optimization (January 2020-December 2021) were selected as the observation group. The rate of pressure injury assessment, accuracy rate of risk assessment, accuracy rate of wound assessment, correct rate of wound treatment, and incidence of in-hospital pressure injury within 2 hours of admission were compared between the two groups. Results The above indexes results between the two groups were as follows (control vs. observation): the rate of pressure injury assessment was 94.7% vs. 99.0% (χ2=7.3, P=0.007); the correct rate of risk assessment was 89.0% vs. 96.3% (χ2=11.9, P=0.001); the correct rate of wound assessment was 74.0% vs. 90.0% (χ2=4.3, P=0.037); the correct rate of wound treatment was 84.0% vs. 96.0% (χ2=4.0, P=0.046), with all the above differences having statistical significance (P
