生脉复律汤辅助治疗非ST段抬高型心肌梗死并室性早搏的疗效及对动态心电图指标、血清NF-κB、IL-6水平的影响

目的 探讨生脉复律汤辅助治疗非ST段抬高型心肌梗死(NSTEMI)并室性早搏(VPB)的疗效及对动态心电图指标、血清核因子κB(NF-κB)、白细胞介素-6(IL-6)、肌钙蛋白I(cTnI)水平的影响。方法 2020年4月—2021年4月在医院确诊的80例NSTEMI并VPB气阴两虚证患者,采用简单随机分组将所有纳入患者分为观察组40例和对照组40例。对照组给予盐酸胺碘酮片治疗,观察组在对照组的基础上给予生脉复律汤辅助治疗。治疗1个月后,分析比较两组患者临床治疗效果,比较治疗前后动态心电图指标[全部正常R-R间期标准差(SDNN)、每5 min R-R间期的标准差(SDANNI)、正常相邻R-R间期差值的均方根(rMSSD)、正常相邻R-R间期差值>50 ms的百分比(PNN50)]、中医证候评分、血清NF-κB、IL-6、cTnI水平差异,并记录治疗期间两组患者不良反应发生情况。结果 治疗后观察组患者临床治疗有效率显著高于对照组(P<0.05);治疗后两组患者的中医证候评分、动态心电图指标、血清NF-κB、IL-6、cTnI水平均减少程度明显优于对照组(P<0.05);观察组患者治疗过程中不良反应发生率为明显低于对照组(P<0.05)。结论 生脉复律汤辅助辅助治疗NSTEMI并VPB气阴两虚证患者有显著的治疗效果,能通过改善患者体内炎症微环境,修复患者心肌损伤,改善患者的心脏功能,且能有效降低不良反应。

复方丹参片合生脉饮抗小鼠心肌缺氧缺血作用研究

目的:观察复方丹参片与生脉饮合用对急性心肌缺氧缺血的作用,为临床应用提供一定实验依据。方法:采用异丙肾上腺素致小鼠急性心肌缺氧模型考察复方丹参片与生脉饮合用对小鼠存活时间的影响,并初步观察量效时效关系;采用垂体后叶素致小鼠急性心肌缺血模型考察二者合用对相关生化指标的影响。结果:复方丹参片与生脉饮合用单次给予,可明显延长心肌缺氧小鼠耐缺氧存活时间,效果优于分别给予,1h左右即有显著药效,起效较缓,作用维持时间较长;并可改善心肌缺血小鼠相关生化指标,包括降低血清丙二醛(MDA)含量及肌酸激酶(CK)、乳酸脱氢酶(LDH)活力,降低心脏组织中MDA、Ca2+、NO含量,升高超氧化物岐化酶(SOD)活力。结论:复方丹参片与生脉散合用对急性心肌缺氧缺血有明显保护作用,具有起效较缓,作用持久的特点。

Sensitivity of Some Biological Objects to Repetitive Submicrosecond Microwave Pulses

The effect of repetitive pulsed microwaves （10 GHz, pulse duration of 100-300 ns, pulse repetition rate of 4-25 pulse per second, peak power density of 0.04-3.5 kW/cm^2） on mastocytoma P815, Ehrlich carcinoma, normal spleen cells and wound healing was investigated. It was found that short-time irradiation with an intensity of 0.9-1.5 kW/cm^2 inhibited proliferation of tumor cells in vitro, whereas at same time it contributes to proliferation of normal spleen cells in vitro. The repetitive pulsed microwaves with an intensity of 0.04-1.5 kW/cm^2 stimulated healing of skin wounds and ulcerations in mice. The effects showed a dependence on the pulse repetition rate and irradiation intensity.

Biomechanical effect of major extremity vessels in choosing repair methods for peripheral artery injury

Objective： To investigate the biomechanical effect of major extremity vessels to choose appropriate repair methods for vascular injuries of the extremities. Methods ： The data of 385 patients （337 males and 48 females, aged 18-71 years, mean = 32.6 years ） including 403 injured vessels, who suffered from vascular injuries of the extremities and were treated in our hospital from October 1960 to August 2005, were studied retrospectively in this article. We compared the results of different repair methods for the defect of vessels and evaluated different injured vessels for repairing arterial injuries with anastomosis and venous graft, respectively. Results： A significant difference was found between the defect lengths of the arteries repaired with anastomosis and venous graft （ P 〈 0. 0001 ）. The upper limits of the confidence interval in the defect lengths of the brachial artery, the femoral artery and the popliteal artery were 3.43 cm, 2. 38 cm and 2. 42 cm, respectively, when repaired with anastomosis. The lower limits were 2.16 cm, 2.16 cm and 1. 63 cm, respectively, when repaired with venous graft. The defect length of each artery repaired with venous graft had linear correlation with the graft length. Conclusion - Because of the longitudinal biomechanical difference of different options of repair arterial injuries. human peripheral vessels, are necessary for different arterial injuries.
