规划是人工智能研究的一个重要方向,具有极其广泛的应用背景.近年来,研究重点已经转移到动态不确定性环境中的规划问题.该文将部分可观察马尔可夫决策过程(POMDP)和过程性推理系统(PRS)的优点相结合,提出一种对动态不确定环境具有更全面适应能力的持续规划系统———POMDPRS.该系统利用PRS的持续规划机制,交叉地进行规划与执行,在一定条件下提高了动态环境中POMDP决策的效率;另一方面,用POMDP的概率分布信念模型和极大效用原理替代PRS的一阶逻辑信念表示和计划选择机制,大大增强了处理环境不确定性的能力.

Background： G-protein β-polypeptide 3 （GNB3） is a β subunit isoform of G-protein that plays important role in signal transduction of membrane G-protein coupled receptors （GPCRs）. The GNB3 splice variant C825T （rs5443） is associated with risk for essential hypertension （EH） and efficacy of therapeutic drugs targeting GPCRs. It is unknown whether the polymorphism is associated with blood pressure （BP） response to telmisartan or amlodipine, two widely prescribed antihypertensive drugs. Methods： A total of 93 subjects initially diagnosed as EH were recruited and underwent a 4-week treatment with telmisartan （42 patients） or amlodipine （51 patients） monotherapy. Both baseline and after-treatment BP were measured. GNB3 C825T polymorphism was genotyped by polymerase chain reaction-restriction fragment length polymorphism. Results： Baseline systolic BP （SBP） and diastolic BP （DBP） were comparable among C825T genotypes in both telmisartan and amlodipine treatment groups. Patients with the CT or TT genotypes showed significantly lower body mass index （BMI） as compared with CC homozygotes in both groups （P 〈 0.05, respectively）. GNB3 825TT homozygotes showed significantly higher alier-treatment DBP and mean arterial presstire （MAP） than those carrying at least one 825C allele （P 〈 0.01） in the telmisartan treatment group. No difference in after-treatment SBE DBP, and MAP levels among C825T genotypes was observed in the amlodipine treatment group. No significant difference in absolute changes in BP levels was observed among the genotypes in either treatment group. Conchlsion： The GNB3 C825T splice variant is associated with the DBP-lowering effect of telmisartan but not amlodipine in Chinese EH patients.
