RESUMEN
We aimed to study the articles and applied prescriptions of Moutan Cortex in Synopsis of theGolden Chamber, summarize and analyze its laws on the disease location and disease nature, and analyze its compatibility, dosage and processing laws. Based on the knowledge of Moutan Cortex by Zhongjing, we found that the kidney, bladder, uterus and intestine involved in Zhongjing's application of peony bark prescription, which belongs to the disease of "lower abdomen" in Huangdi Nei Jing. And the prescription of Moutan Cortex mainly focused on the syndromes of "depression" and "blood stasis", which are characterised by five kinds: water depression, dampness depression, stasis-heat, blood stasis and ecchymosis. and the compatibility rule of Zhongjing application of Moutan Cortex is analyzed accordingly. In addition, the study found that as the downward movement of the disease position, the amount of Moutan Cortex increased, and the processing of the problem followed the principle of "if disease is slow onset, the Moutan Cortex heart should be removed, but if disease is acute, Moutan Cortex heart should be kept". Finally, we combined modern clinical application of Moutan Cortex with modern pharmacological research, in order to expand the scope of clinical application of Moutan Cortex and "the same treatment of different diseases" to provide theoretical guidance.
RESUMEN
Cervical cancer is a gynecological malignant tumor with a high incidence in the world. With the insidious onset and lack of obvious symptoms and signs in the early stage， 13% of cervical cancer patients are diagnosed in the advanced stage of the disease， and the 5-year survival rate of metastatic cervical cancer is only 16.5%. So far， surgery and radiotherapy/chemotherapy are still the basic means for the treatment of cervical cancer. However， with the emergence of toxicity， drug resistance， and other side effects， there are still some limitations in the clinical application of these therapies. In recent years， natural compounds represented by polysaccharides have been found to have a significant anti-cervical cancer effect， which has attracted extensive attention from researchers in China and abroad. Widely distributed in the roots， stems， leaves， flowers， and fruits of higher plants， plant-based polysaccharides are important components of natural polysaccharides， as well as multimers with a complex structure and biological response regulators， which have been widely studied in the fields of cancer， cardiovascular， endocrine， and other diseases. This study reviewed the research on the anti-cervical cancer effect and mechanism of natural plant-derived polysaccharides by consulting the literature in the past 20 years to bring breakthroughs in the research and development of anti-cervical cancer new drugs. Through the literature review， the results indicated that natural plant-derived polysaccharides could exert anti-tumor effects by inhibiting cell proliferation， promoting apoptosis， inhibiting invasion and migration， promoting autophagy， arresting cell cycle of cervical cancer cells， regulating epithelial-mesenchymal transition （EMT）， resisting oxidative stress， inhibiting tumor angiogenesis， improving immunomodulatory activity， and regulating signaling pathways. It should be noted that in the current research on natural plant-derived polysaccharides against cervical cancer， the bioavailability of some natural polysaccharides is low and a considerable proportion of the research is limited to the in vitro experiment. Therefore， it is urgent to carry out more clinical experimental studies on the anti-cervical cancer of natural plant-based polysaccharides to obtain a more reliable theoretical and practical basis.
RESUMEN
Endothelial cells in the inner wall of blood vessels respond to physical and chemical signals of the body by regulating vascular homeostasis， vascular tension， cell adhesion， cell proliferation， coagulation resistance and inflammatory factors， to maintain the stability of blood vessels. Angiogenesis is the key condition for tumor evolution， and the pathological mode of tumor angiogenesis provides nutrients and oxygen for tumor growth and promotes its proliferation. In recent years， endothelial cells have participated in tumor vascular infiltration and driven angiogenesis， which is considered to be the point link in tumor metastasis. By regulating metabolic remodeling， vascular endothelial cells provide the materials and energy needed in the process of tumor angiogenesis， and their abnormal metabolic characteristics facilitate their adaption to the changes of tumor microenvironment， which is often regarded as an important basis for tumor angiogenesis. The ''Yin fire'' theory in traditional Chinese medicine， originating from Huangdi's Internal Classic （Huang Di Nei Jing）， originally meant Yin deficiency generates internal heat， and belonged to the category of fire of internal injury. After the deduction and changes by physicians over the ages， the pathogenesis of ''spleen and stomach Qi deficiency-Yin fire rising-Qi and fire disharmony'' was gradually formed. The pathogenesis of metabolic remodeling of endothelial cells manifests the pathological characterization of Yin fire in an objective way， which is consistent with the disease state of uncontrolled and hyperactive tumor neovascularization. Changes in spleen and stomach Qi deficiency as well as imbalance of Qi movement lead to the failure of water and food in distribution， and thus metabolic disorders occur. Long term retention turns in phlegm and blood stasis， which combat with blood vessels， and result in abnormal local environment （formation of tumor microenvironment）， adverse pulse channel （imbalance of endothelial cell metabolism）， and tumor neovascularization. Under the guidance of ''Yin fire'' syndrome elements and by focusing on the correlation between Qi and fire， prescriptions are made based on the treatment method of ''strengthening the body and regulating Qi'' to regulate the metabolic function of endothelial cells， thus achieving a relatively balanced state of the body and inhibiting tumor angiogenesis. As a result， this study， centering on the metabolic remodeling of endothelial cells and ''Yin fire'' theory， elucidated the academic ideas， with the purpose of providing some theoretical support for the intervention of tumor vascularization by Chinese medicine.
RESUMEN
Objective To investigate the interventional effect of multidimensional strategy to reduce the incidence of neonatal ventilator-associated pneumonia.Methods The patients who were admitted to the NICU department and received mechanical ventilation (MV) for more than 48 hours from October 2012 to September 2014 were recruited. The control group received the experienced interventions from October 2012 to September 2013, neonates from October 2013 to September 2014 were recruited as the intervention group receiving multidimensional controlling strategy, including bundle care, education, pro-cess and outcome surveillance and feedback on the practices. The compliance of before-after implementation of interventions were quantitatively evaluated,and the rate of VAP was compared between the two groups.Results The compliance rate of hand hygiene and the qualiifed rate of sputum suction, oral care, drain condensation from ventilator circuit, semi-recumbent posi-tion, and preventing of stress-ulcers were increased 17.0%, 11.4%, 14.7%, 18.2%, 37.5% and 56.3% respectively after implemen-tation of multidimensional strategy, and had statistical difference (χ2=36.47-294.36,P0.05). The VAP rate was 41.7 cases per 1000 MV-days during control group and 19.7 cases per 1000 MV-days during intervention group, had statis-tical signiifcance (P0.05). ConclusionThe multidimensional strategy can effectively prevent the incidence of VAP.
