Methods A randomized controlled trail was carried out in 41 patients. The medication design was based on the findings that the half life time of salvianolate was less than 2 h and its time of clearance uas 12 h. The treatment group (n=20) was treated with salvianolate at the dose of 200 mg, intravenous drip, twice a day, and the control group (n=21) with salvianolate at the dose of 200 mg, intravenous drip, once a day. The curative effects of salvianolate on angina pectoris (with syndrome of heart-blood obstruction) in the two groups was compared.

通过大量的试验研究提出了注水水质调控方法，通过以采油二厂七中东八道湾组油藏为主，分析了水质控制指标的变化带来的注水井吸水能力的变化，预测了注水井的伤害半径以及吸水能力变化的半衰期。

The maximum absorption peak was at long wavelength (＞650nm), extinction coefficient achieves 10〓 degree, which was one degree higher than HpD. The study has revealed that CPD photosensitizer appeared blue movement under the relevant body environment. The spectra parameters provided basis for selecting light source of PDT. Measurement system which measured singlet oxygen and its quantum yields within the infare range had been set up and the quantum yields of singlet oxygen for CPD were reported: the quantum yields of singlet oxygen for CPD〓 was the highest (φ=0.83) while he quantum yields of singlet oxygen for CPD〓 was the lowest (φ=0.83). Photobleaching's half life time was studied.

给出了此类光敏剂的光谱指认和光谱参数：其吸收光谱峰值位于长波红光区(＞650nm)，摩尔消光系数达10〓LmoL〓cm〓量级，比血卟啉衍生物高出一个数量级；研究揭示了此类光敏剂在近似体内环境下光吸收的蓝移现象，为光动力治疗光源的选择提供了依据；建立了在近红外光谱区中测定敏化单态氧的光谱和量子产率测量系统，报导了该类光敏剂敏化单态氧的量子产率，其中CPD〓的单态氧量子产率最高(φ＝0.83)，CPD〓的单态氧量子产率最低(φ＝0.51)；测定了二氢卟吩类光敏剂的光漂白半衰期。
