ABSTRACT
Objective:To investigate the clinical efficacy of the Guanxinning tablet on the prethrombotic state in older adults with stable angina pectoris.Methods:In this study, 80 elderly patients with coronary heart disease and blood stasis admitted to our hospital between December 2019 and December 2021 were selected as the study subjects, and were randomly divided into a control group and an observation group(40 cases each). The control group was treated with Aspirin alone, and the observation group was treated with the Guanxinning tablet in addition to aspirin.Differences in traditional Chinese medicine(TCM)syndrome scores, weekly angina attacks and intervals between attacks, von Willebrand factor(vWF), thrombomodulin(TM), and granule membrane protein-140(GMP-140)levels between the two groups were compared.Results:There was no statistically significant difference in TCM syndrome scores between the observation group and the control group before treatment(11.34±2.2 vs.11.8±2.3, t=0.184, P=0.856), but there was a statistically significant difference between the observation group and the control group after treatment(6.5±1.8 vs.8.4±2.0 points, t=4.230, P=0.000). The number of weekly angina attacks and the interval between attacks in the observation group were significantly decreased compared with the control group, and the difference was statistically significant(all P<0.01). The levels of molecular markers of the prethrombotic state(vWF, TM and GMP-140)in the observation group were more favorable than those in the control group, with statistical significance(all P<0.05). Conclusions:The Guanxinning tablet can improve angina pectoris symptoms in elderly patients with coronary heart disease and effectively improve the expression of molecular markers of the prethrombotic state.
ABSTRACT
Objective To compare the accuracy of somatosensory evoked potentials(SSEPs), motor evoked potentials(MEPs), regional cerebral oxygen saturation(rSO2)and multimodal monitoring in monitoring cerebral ischemia in patients undergoing carotid endarterectomy(CEA). Methods Eighty American Society of Anesthesiologists physical status Ⅱ or Ⅲ patients of both sexes, aged 46-76 yr, scheduled for elective CEA, were enrolled in the study. SSEPs, MEPs and rSO2were monitored during CEA. The event of intraoperative cerebral ischemia was defined as:(1)SSEP escape latency prolongation of 10% and∕or amplitude decrease of 50%;(2)disappearance of MEP amplitude;(3)decrease in rSO2>20% of the baseline value;(4)When multimodal monitoring was applied, the event of intraopera-tive cerebral ischemia could be defined as long as one variable previously described met the condition. The gold standard of perioperative cerebral ischemia was defined as:(1)the National Institutes of Health Stroke Scale score≥4 at 1, 3 and 5 days after operation than before operation was considered as neurologi-cal dysfunction;(2)cranial CT showed a new ipsilateral cerebral focal ischemia, and postoperative in-tracranial hemorrhage diseases were excluded. Results Five cases developed cerebral ischemia after opera-tion. The sensitivity and specificity of SSEPs in predicting cerebral ischemia were 80% and 83%, respec-tively;MEPs 80% and 80%, respectively; SSEPs+MEPs 100% and 79%, respectively; rSO260% and 93%, respectively;SSEPs+MEPs+rSO2100% and 7%, respectively. Decrease in rSO2> 20% of the base-line value was consistent with SSEP escape latency prolongation of 10% and∕or amplitude decrease of 50%in diagnosis of cerebral ischemia(Kappa value 0.67, P<0.01); decrease in rSO2>20% of the baseline value was consistent with disappearance of MEP amplitude in diagnosis of cerebral ischemia(Kappa value 0.54, P<0.01). Conclusion rSO2has a good agreement with SSEPs and MEPs in diagnosis of cerebral ischemia during CEA; combination of SSEPs and MEPs produces better accuracy in monitoring cerebral is-chemia.
ABSTRACT
Objective To investigate the effects of Naoxintong Capsule treatment on the carotid artery intima media thickness(IMT),plasma beta thromboglobulin(beta TG),P-selectin(CD62p)and plasminogen activator inhibitor 1 (PAI 1)in elderly patients with type 2 diabetes mellitus and subclinical atherosclerotic vascular disease.Methods In retrospective study,110 cases of elderly patients with type 2 diabetic vascular diseases were selected and admitted as study subjects from June 2014 to May 2015.They were randomized into observation group and control group(n=55,each).All patients were given routine treatment.The patients in the observation group were treated with Naoxintong Capsule.The levels of plasma β-TG,CD62p and PAI 1 were measured and compared between two groups.Results Before treatment,there were no significant differences in IMT,PAI 1,β-TG and CD62p levels between the two groups(P＞0.05).After treatment,the observation group versus control group showed an improved four parameters of carotid artery IMT(1.31 ±0.26)mm vs.(1.44±0.26)mm,PAI 1(2.23 ±0.48)μg/L vs.(2.56 ±0.61)μg/L,β-TG(29.76 ± 10.24)μg/L vs.(35.98 ± 10.35)tμg/L,CD62p(162.3 ± 21.5)ng/L vs.(176.96 ± 20.3)ng/L(t=4.058,3.965,11.293,14.624 respectively,all P ＜ 0.05) with statistically significant differences.Conclusions Naoxintong Capsule treatment of type 2 diabetic patients with subclinical atherosclerotic vascular disease can reduce carotid intima-media thickness,decrease platelet releasing activity and lower the oxidative stress reaction.Thereby,it protects the vascular endothelium,and alleviates subclinical atherosclerotic vascular disease in the elderly type 2 diabetic patients.

ABSTRACT
Objective To investigate influence of amlodipine /atorvastatin on atherosclerosis in the elderly with hypertension and hyperlipidemia.Methods Totally 108 cases with hypertension and hyperlipidemia in our hospital were randomly divided into control group and observation group (n =54 each).The control group received conventional antihypertensive treatment such as diuretics,angiotensin-converting enzyme inhibitors,calcium antagonists; the observation group received amlodipine and atorvastatin combination tablet as add-on therapy to the above drugs for 6 months.The blood lipid level and carotid artery ultrasound detection results were observed and compared between the two groups after treatment.Results The levels of TC[(4.23 ± 0.79)mmol/L vs.( 5.32 ±1.23)mmol/L],TG[(1.53±0.35) mmol/L vs.(5.32± 1.23) mmol/L],LDL-C [(3.19 ± 0.59)mmol/L vs.(4.07±0.79)mmo1/L]were decreased,while HDL-C [(1.53±0.95)mmol/L vs.(1.32±0.83)mmol/L]were increased in observation group after treatment as compared to control group (all P ＜0.05).After carotid artery ultrasonography,the LN[( 1.61± 0.76) scores vs.( 2.24 ± 0.89) scores ] and IMT [(0.76 ± 0.22)mm vs.(0.98 ± 0.28)mm] levels were lower in observation group after treatment than in control group (P＜0.05).Conclusions Amlodipine/atorvastatin combination can reduce blood lipids and alleviate atherosclerosis.It is suitable for elderly patients with hypertension and hyperlipidemia.
ABSTRACT
Objective Looking into the causes of self-regeneration obstacle of the wild Phellodendron amurense population in order to provide the reference for the sutdy of the germination mechanism. MethodsThe germination and seedling growth were observed by taking cabbage, wheat, and P. amurense as the tested objects and the sarcocarp and seed of P. amurense were extracted by alcohol and ethyl ether. Results The extract in sarcocarp and seed of P. amurense could decrease the germination rate of cabbage, wheat, and P. amurense seed, also inhibit the seedling growth in different levels. The inhibitory effect was getting stronger and stronger following the concentration increased. The ethyl ether extract showed the best inhibitory effect, while the water extract had no significant effect. The embryo, emdosperm, and cotyledon of P. amurense were extracted by distilled water, and among them the cotyledon had the strongest inhibition. Conclusion There are some substances with the better inhibitory effect in the sarcocarp and seed of P. amurense, which can inhibit the growth of itself and other plants significantly. The substance with the inhibitory effect exits mainly in cotyledon.
