ABSTRACT

In recent years, coronary microvascular disease (CMVD), a main type of ischemic heart disease with high incidence and low diagnosis rate, has become a new research hotspot and received much clinical attention. The etiology of CMVD is complex and the symptoms are various. Traditional Chinese and Western medicine have different opinions on its pathogenesis and treatment plan. Western medicine believes that CMVD is related to structural abnormalities (such as microvascular remodeling, vascular invasion, lumen obstruction, sparse vascular vessel and perivascular fibrosis) and functional abnormalities (such as endothelial dysfunction, smooth muscle cell dysfunction, microvascular constriction, microvascular spasm, inflammation and autonomic nervous dysfunction) of coronary microvascular vessels as well as the extravascular factors (such as heart rate and blood pressure). In clinics, conventional western medicines are usually used for empirical treatment, but with undesirable effects. Traditional Chinese medicine (TCM) believes that CMVD belongs to the category of "chest impediment", "heart pain" and "collateral disease", and the common syndromes include Qi deficiency and blood stasis, Qi stagnation and blood stasis, Qi and Yin deficiency, congealing cold in heart vessel, heart and spleen deficiency, blood stasis obstructing collaterals, combined phlegm and blood stasis, and liver and kidney deficiency, with a variety of treatment methods. Specifically, Chinese patent medicines, self-designed prescriptions, modified classical prescriptions and TCM characteristic therapies have achieved certain effects. This review discussed the risk factors, pathological mechanism, TCM etiology and pathogenesis and traditional Chinese and Western medicine treatment of CMVD, to provide reference for the study and treatment of CMVD.

ABSTRACT

Shexiang Baoxin pills (SBP) are prescribed based on Suhexiang Pills derived from the Formulary of the Bureau of Taiping People's Welfare Pharmacy (《太平惠民和剂局方》) in the Song Dynasty. As the classic Chinese patent medicine in warming and dredging with aromatics, SBP have been widely used in clinical treatment for 30 years by virtue of their unique efficacy in coronary atherosclerotic heart disease (CHD). Angiogenesis is a biological process in which the body activates angiogenesis-related factors in the body to act on endothelial cells under local vascular injury, tumor growth, local inflammation, and other stimuli to promote the proliferation, migration, and infiltration of endothelial cells, and form new sprouting or non-sprouting blood vessels. As a new strategy for ischemic diseases such as CHD, therapeutic angiogenesis is of great significance in the prevention and treatment of CHD in promoting angiogenesis of ischemic myocardium and establishing effective collateral circulation. However, for the atherosclerotic plaque and tumor, angiogenesis promotion is a risk factor for accelerating the disease progression. Therefore, safe and effective regulation of ischemic myocardial angiogenesis has become the focus of the current prevention and treatment of CHD. Studies in recent years have shown that SBP can intervene in angiogenesis with multiple pathways and targets, which can exert therapeutic angiogenesis effect on CHD and also inhibit atherosclerotic plaque and tumor angiogenesis to varying degrees. This study reviewed the experimental and clinical trials on the regulatory effect of SBPs on angiogenesis in CHD to provide references for the research on Chinese medicine intervention in angiogenesis of CHD.

ABSTRACT

Objective:To evaluate the clinical efficacy and safety of compound glycyrrhizin combined with tripterygium wilfordii polyglycosides for psoriasis.Methods:Literature search was conducted in CNKI, Wanfang, VIP databases, Sinomed, PubMed, the Cochrane Library and Embase with the deadline of September 28th, 2020. The randomly controlled trials of compound glycyrrhizin combined with tripterygium wilfordii polyglycosides in treating psoriasis was included. The publication bias and methodology quality of RCTs were evaluated according to the Cochrane 5.0.1 bias risk assessment method. The RevMan 5.3 software was used for meta analysis.Results:Ten studies with 961 patients were included, with the experimental group ( n=486) and the control group ( n=475). The results of meta-analysis showed that the total effective rate [ OR=3.16, 95% CI (2.00-4.99), P<0.001], the cure rate [ OR=2.56, 95% CI (1.94-3.61), P<0.001], the recurrence rate [ OR=0.15, 95% CI (0.04-0.60), P=0.007], the total incidence of adverse reactions [ OR=0.53, 95% CI (0.34-0.82), P=0.004], the incidence of abnormal liver function [ OR=0.17, 95% CI (0.06-0.47), P=0.001] in the experimental group were better than those in the control group. There was no significant difference on the incidence of adverse reactions of digestive tract ( P>0.05) or lower extremity or facial edema ( P>0.05) between both groups. Conclusions:Compound glycyrrhizin combined with tripterygium wilfordii polyglycosides is effective in the treatment of psoriasis than tripterygium wilfordii polyglycosides alone, and can reduce the recurrence rate and the incidence of adverse reactions. However, a large number of large samples and high-quality studies are still needed.

ABSTRACT

<p><b>OBJECTIVE</b>To compare the effects between fast acupuncture and retaining acupuncture for the cervical type of cervical spondylosis.</p><p><b>METHODS</b>Sixty patients were randomized into a fast acupuncture group and a retaining needle group, 30 cases in each one. The acupoints in the two groups were Fengchi (GB 20), Jiaji (EX-B 2, C, C, C) and Jianjing (GB 21), Jianjing 1 (Extra) and Jianjing 2 (Extra). The needles in the fast acupuncture group were out afterarrival, while those in the retaining needle group were retained for 30 min, three times a week, once the other day. One week was seen as a course and the treatment was given for 2 courses. The indices were observed before and after treatment, including Northwick Park neck pain questionnaire (NPQ), short-form McGill pain questionnaire (SF-MPQ) [pain rating index (PRI), visual analogue scale (VAS) and present pain intensity (PPI)]. The effects were compared in the two groups.</p><p><b>RESULTS</b>After treatment, the NPQ score was lower than that before treatment in the two groups (both<0.01), and that in the fast acupuncture group was better (<0.01). All the items of SF-MPQ decreased compared with those before treatment in the two groups (all<0.01), with the better results of PRI sensation score and PRI total score in the fast acupuncture group (both<0.05). The PRI feeling score, VAS score, and PPI score were not significantly different after treatment between the two groups (all>0.05). The total effective rate in the fast acupuncture group was 83.3% (25/30), not significantly different from 76.7% (23/30) in the retaining needle group (>0.05).</p><p><b>CONCLUSION</b>Fast acupuncture and retaining needle are both effective for the cervical type of cervical spondylosis, which can apparently improve the clinical symptoms. Fast acupuncture is superior to retaining acupuncture.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To observe the injury in rat primary cultured neurons induced by Abeta(1-40) and the protective effects of combination of ginseng and ginko extracts.</p><p><b>METHOD</b>Primary neurons were induced by Abeta(1-40) to establish the cell model of toxic injury. Using flow cytometry with Annexin V-FITC/PI double staining, MTP assay, transmission electron microscopy and Western blot, the appropriate concentration and duration of AP for cell model establishment were determined. The effects of extracts of ginseng and ginko (EGGB)on cellular proliferative activity, apoptotic rate, ultrastructure and caspase-3 expression were detected.</p><p><b>RESULT</b>The apoptotic rate was increased significantly after neurons were induced by 1 micromol x L(-1) Abeta(-40) for 24 h (P < 0.01). EGGB (5, 50 mg L(-1)) significantly enhanced the proliferative activity (P < 0.05). Meanwhile, EGGB (50 mg L(-1)) inhibited neuronal apoptosis and caspase-3 overexpression and improved cellular ultrastructure remarkably (P < 0.05, P < 0.01).</p><p><b>CONCLUSION</b>Abeta(1-40) could significantly induce primary cultured neurons to apoptosis in vitro. EGGB showed beneficial neuroprotective effects against neuronal apoptosis, which might be due to improving the structures of neuron and its subcellular organelles, enhancing cellular proliferative activity and inhibiting caspase-3 overexpression in neurons.</p>

ABSTRACT

AIM: To investigate the effects of Shuguan Capsule on myocardial blood flow (MBF) and myocardial oxygen consumption (MOC) in anesthetized dogs. METHODS: Coronary blood flow (CBF) of twenty-five thoracotomized dogs was detected by electromagnetic flow meter and the MBF was calculated. While the oxygen content in the artery (AO2 ) and in the coronary venous sinus (VO2) was determined with blood oxygen analysis.Moreover, the other cardiac hemodynamic parameters, such as heart rate (HR), femoral arterial blood pressure (BP), were observed by physiological polygraph. RESULTS: It was found that Shuguan Capsule (48.5 mg/kg and 194 mg/kg) could significantly increase the MBF, and then decease the coronary artery resistance. Furthermore, Shuguan Capsule could also lower the AO2, but increase the VO2, which led to the decreased MOC. CONCLUSION: Shuguan Capsule exhibits the effects to keep the balance between blood supply and oxygen consumption in the heart by modulating the coronary resistance and by reducing MOC in dogs.

ABSTRACT

Alzheimers disease (AD) is a progressively and retrogressively neurodegenerative disorder characterized by two hallmarks: senile plaques (SP) and neurofibrillary tangles (NFTs). The studies of animal models, which are crucial to the further study of AD, will promote the understanding of the etiology, mechanisms and medicine screening. Although the animal models such as experimental injury, normal aging and compound types could represent the cognitive deficit, they lack the essential neuropathological characteristics of AD. Senescence accelerated mouse / prone 8 is one of relatively practical and stable models. The most enchanting focus of AD models is transgenic mice that provide new carriers for the research of pathogenic forms of specific genes and metabolites thereof in vivo. As therapies of AD evolve from symptomatic treatment to causative treatment,so must the animal models of AD.
