RESUMEN
Objective To study the effect of type 2 diabetes mellitus (T2DM) on the cerebral blood vessels in Alzheimer's disease (AD), and to explore its mechanism of influence on the pathogenesis of Alzheimer's disease. Methods To generate a mouse model with AD complicated with long-term T2DM, forty 6-month-old APP/PS1 transgenic mice were fed with high-sugar and high-fat diet for 6 months, that was, when mice at 12 months of age, they were intraperitoneally injected with 1% streptozotocin solution for 4 consecutive days. Then, mice were randomly divided into 4 groups: the normal control group, AD model group, T2DM model group and AD complicated with T2DM model group, 10 mice were used in each group. The learning and memory ability of the mice were tested by the mouse step-down assay, and the vascular morphology of the mice's hippocampal CAI area was observed by ink perfusion. Then oil red 0 staining and immunofluorescent staining were applied to test the pathological indices of the hippocampal area in the model. Results Compared with the control group, AD combined with T2DM mice showed decreasing significantly abilities in the learning and memory (P<0.05), and the blood vessels in the hippocampus became thinner and the vascular density decreased. Moreover, T2DM promoted lipid deposits and vascular leak in the hippocampus of the model. Additionally, the expression of β-site amyloid precursor protein cleaving enzyme-1 (BACE-1), nuclear factor (NF)-κB and matrix metalloproteinase (MMP) -9 were increased compared with the controls in the hippocampal CAI region. Conclusion T2DM plays a negative regulatory role on learning and memory functions of mice, accelerates the onset of AD and result in cerebrovascular lesions. In addition, the abnormal expression of MMP-9 may also be one of the causes of AD vascular lesions.

RESUMEN
Objective:To analyze the syndrome characteristics and distribution regularity of patients with non-ST segment elevation myocardial infarction (NSTEMI), in order to guide clinical practice and improve the efficacy of traditional Chinese medicine. Method:Inpatients with non-ST segment elevation myocardial infarction in line with the diagnostic criteria were selected, and the frequency statistics method was used to analyze the syndrome elements and their frequency degree and distribution characteristics. Result:According to the analysis of syndrome elements and their frequency degree of 263 patients with NSTEMI, the pathogenesis of NSTEMI was mostly deficiency in origin and excess in superficiality. As for deficiency in origin, Qi deficiency (171 times, 32.39%) was the most common, which was followed by Yin deficiency (42 times, 7.95%), Yang deficiency (16 times, 3.03%), and blood deficiency (1 times, 0.19%). As for excess in superficiality, blood stasis (129 frequency, 24.4%) and phlegm turbidity (125 frequency, 23.7%) were the most common, which were followed by heat accumulation (42 frequency, 7.95%), water drinking (2 frequency, 0.38%). According to the syndrome diagnosis analysis of the combination of syndrome elements, 220 cases (83.65%) had single syndrome differentiation, 42 cases (15.97%) had two syndromes at the same time, and 1 case (0.38%) had three syndromes at the same time. Among all the syndrome types, Qi deficiency and blood stasis syndrome (94 cases, 42.7%) was the most common, which were followed by phlegm and blood stasis syndrome (46 cases, 20.9%), Qi and Yin deficiency syndrome (41 cases, 18.6%) and heart and kidney deficiency syndrome (32 cases, 14.6%). And Yang deficiency and water flooding syndrome (6 cases, 2.73%) and heart fire blazing syndrome (1 case, 0.45%) were relatively rare. According to the distribution regularity of syndrome, traditional Chinese medicine therapies were mainly for tonifying vital qi and protecting kidney Qi, with equal emphasis on removing phlegm, eliminating dampness and diuresis, activating blood circulation and removing blood stasis. Conclusion:The pathogenesis of NSTEMI is deficiency in origin and excess in superficiality. Deficiency in origin is mostly Qi deficiency and Yin deficiency, while excess in superficiality is mostly blood stasis, phlegm and heat accumulation. traditional Chinese medicine therapies are mostly for invigorating Qi and nourishing Yin, promoting blood circulation and removing blood stasis, clearing heat and resolving phlegm.
RESUMEN
Coronary heart disease (CHD) has become a major disease that seriously endangers human health. It belongs to the category of " chest obstruction" and " genuine heart pain" in Chinese medicine, and blood stasis syndrome is its core pathogenesis of CHD, which runs through the disease all the time. On the basis of more than 30 years' clinical practice and taking " blood stasis syndrome of CHD" as the research object, the research group has carried out a comprehensive, in-depth and systematic studies on diagnostic criteria, biological basis, and evidence-based evaluation. The quantitative diagnostic criteria of blood stasis syndrome of CHD were established, and the research directions of quantification and objectivity of Chinese medicine syndromes were innovated. The biological basis of blood stasis syndrome of CHD was revealed from macroscopic characterization to organ cell molecular level. When the above research results are applied in the prevention and treatment, the accuracy of diagnosis and the clinical efficacy for CHD has been improved in Chinese medicine.
RESUMEN
Objetive To investigate the effect of Qingkailing injection on the expression of Toll-like receptor 4 (TLR4), gp91phox and zonula occludens-1 (ZO-1) in cerebrovascular endothelial cells induced by hypoxia activation of microglias. Methods:BV2 microglia cells were divided into six groups. They were cultured in serum-free DMEM, while the Qingkailing groups of low, middle and high dosages were cultured with 0.0625%, 0.125% and 0.25% Qingkailing injection, respectively, and minocycline group with minocycline of 200 nmol/L. The groups other than control group underwent hypoxia for 24 hours and reoxygenation for 24 hours. Then, the medium of microglia was put into the medium of Balb/c endothelial cells for 24 hours. The cell viability of endothelial cells was measured with CCK-8, the concentration of nitric oxide (NO) was detected with colorimetry, and the experission of TLR4, gp91phox and ZO-1 was detected with Western blotting. Results:Compared with the control group, the cell viability and the expression of ZO-1 decreased in the model group (P < 0.01), while the concentration of NO and the expression of TLR4 and gp91phox increased (P < 0.05). Compared with the model group, the cell viability and the expression of ZO-1 increased in the Qingkailing groups and the minocycline group (P < 0.05), while the concentration of NO and the expression of TLR4 and gp91phox decreased (P < 0.05). Conclusion:Qingkailing injection may enhance the survival and function of cerebrovascular endothelial cells by inhibiting the hypoxia activation of microglias, reducing the expression of TLR4 and gp91phox, and increasing the expression of ZO-1.
RESUMEN
Acute altitude reaction is a stress response of organism to special altitude environmental factors such as hypoxia, low pressure, cold, dry and strong ultraviolet. As it is the most incident disease in high altitude areas, its prevention remains a problem to be solved. In China, the traditional Chinese (Tibetan) medicines have been recognized as an effective means of preventing and treating acute altitude sicknesses. Some single-recipe or compound traditional Chinese (Tibetan) medicines have been proved to be effective for acute altitude sicknesses. In this article, we will describe traditional Chinese (Tibetan) medicines of different types with efficacy in prevention and treatment of altitude sicknesses.
