Salvianolic Acid A Protects Neonatal Cardiomyocytes Against Hypoxia/Reoxygenation-Induced Injury by Preserving Mitochondrial Function and Activating Akt/GSK-3β Signals / 中国结合医学杂志

OBJECTIVE@#To investigate the effects of salvianolic acid A (SAA) on cardiomyocyte apoptosis and mitochondrial dysfunction in response to hypoxia/reoxygenation (H/R) injury and to determine whether the Akt signaling pathway might play a role.@*METHODS@#An in vitro model of H/R injury was used to study outcomes on primary cultured neonatal rat cardiomyocytes. The cardiomyocytes were treated with 12.5, 25, 50 μg/mL SAA at the beginning of hypoxia and reoxygenation, respectively. Adenosine triphospate (ATP) and reactive oxygen species (ROS) levels were assayed. Cell apoptosis was evaluated by flow cytometry and the expression of cleaved-caspase 3, Bax and Bcl-2 were detected by Western blotting. The effects of SAA on mitochondrial dysfunction were examined by determining the mitochondrial membrane potential (△Ψm) and mitochondrial permeability transition pore (mPTP), followed by the phosphorylation of Akt (p-Akt) and GSK-3β (p-GSK-3β), which were measured by Western blotting.@*RESULTS@#SAA significantly preserved ATP levels and reduced ROS production. Importantly, SAA markedly reduced the number of apoptotic cells and decreased cleaved-caspase 3 expression levels, while also reducing the ratio of Bax/Bcl-2. Furthermore, SAA prevented the loss of △Ψm and inhibited the activation of mPTP. Western blotting experiments further revealed that SAA significantly increased the expression of p-Akt and p-GSK-3β, and the increase in p-GSK-3β expression was attenuated after inhibition of the Akt signaling pathway with LY294002.@*CONCLUSION@#SAA has a protective effect on cardiomyocyte H/R injury; the underlying mechanism may be related to the preservation of mitochondrial function and the activation of the Akt/GSK-3β signaling pathway.

Study on TCM Dominant Diseases Based on Diagnosis Related Groups Data / 中国中医药信息杂志

Objective To screen TCM dominant diseases from service efficiency, service quality and security by taking a three-A-grade TCM hospital as example.Methods According to the diagnosis related data of the TCM hospital, the common diseases in major disease categories (MDC) were screened out. Average cost of hospitalization, average hospitalization days, antibiotic use rates, blood use rates, and mortality rates were compared with the average level of tertiary general hospitals.Results Totally 27 common diseases were screened out. Three diseases had advantages in terms of service efficiency, security and service quality; 14 diseases had security advantage; 13 diseases had advantage in service quality.Conclusion Compared with three-A-grade general hospitals, most of the common diseases in the hospital has obvious advantages in security and service quality, but the average length of hospitalization in the hospital is longer, and the average cost of most of the common diseases is higher than the general hospital, without advantages in service efficiency.

Study on Policy of Promoting the Role of Traditional Medicine in Primary Health Care Services / 中国中医药信息杂志

How to use traditional medicine to play the role of primary health care to achieve strategic objectives of universal health coverage and health for all is an important issue for traditional medical development. World Health Organization (WHO) called out that the health system should return to primary health system which was officially launched 30 years ago. "Universal Health Coverage" was list as one of the overall objectives of WHO overall program in 2014-2019. WHO advocated incorporating traditional medicine into primary health care system to promote universal health coverage. At the same time, under the new situation of returning to the "basic health care", China has accumulated rich experience in incorporating TCM into basic health care system. Chinese medicine service has been successfully incorporated into the national basic public health services in grassroots medical institutions, and Chinese medicine service capacity has also been significantly improved under the guidance of good policy.

Study on the anti-apopotosis induced by hypoxia/hypoglycemia and reoxygenation of panax notoginseng saponins in cultured rat hippocampal neurons / 中国中药杂志

<p><b>OBJECTIVE</b>To study the inhibitory effects of Panax Notoginseng Saponins(PNS) on apoptosis induced by hypoxia/hypoglycemia and reoxygenation in cultured rat hippocampal neurons.</p><p><b>METHOD</b>Apoptosis were measured by flow cytometry, intracellular free calcium concentration([Ca2+]i) was measured with confocal laser scanning microscopy, morphological changes and neuronal necrosis were observed with fluorescence microscope, and meanwhile the leakage of lactic dehydrogenase(LDH) was measured.</p><p><b>RESULT</b>Hypoxia/hypoglycemia cultures for 5 hours and reoxygenation induced neuronal apoptosis and necrosis, and significantly increased neuronal [Ca2+]i and the leakage of LDH. The effects were increased with the extending time of reoxygenation. PNS has could significantly decrease the percentage of neuronal apoptosis and necrosis, and reduce neuronal [Ca2+]i and the leakage of LDH.</p><p><b>CONCLUSION</b>PNS has inhibitory effect on neuronal apoptosis. This effect might be related to its effect of decreasing intracellular free calcium concentration.</p>
