ABSTRACT
Yigongsan， derived from QIAN Yi’s Key to Therapeutics of Children’s Diseases in the Song Dynasty， is a classic pediatric prescription that is included in the Catalogue of Ancient Classic Prescriptions （the Second Batch of Pediatrics） released by the National Administration of Traditional Chinese Medicine in 2022. This paper verifies and analyzes the historical origin， composition， dosage， processing， decoction method and efficacy of Yigongsan by systematically combing ancient books and modern documents. As a result， Yigongsan is composed of five herbs： Panax ginseng， Poria cocos， Atractylodes macrocephala， Citrus reticulata and Glycyrrhiza uralensis， of which P. cocos should be peeled， A. macrocephala is fried with soil， G. uralensis is roasted with honey while P. ginseng and C. reticulata are raw products. According to the dosage of ancient and modern times， each medicinal herb must be ground into fine powder， 1.6 g for each， added with 300 mL of water， 5 pieces of Zingiber officinale， and 2 Ziziphus jujuba， decocted together to 210 mL， and taken before meals. In ancient books， Yigongsan is used to treat vomiting， diarrhea， spleen and stomach deficiency， chest and abdominal distension， and lack of appetite， etc. Modern research showed that Yigongsan could also be used in the diseases of immune system， respiratory system， blood system， etc.， involving infantile anorexia， asthma， anemia， tumors and so on.
ABSTRACT
Alzheimer's disease(AD)is a neurode-generative disease with complex pathological mecha-nism characterized by accumulation of amyloid plaques and neurofibrillary tangles in the brain.Increasing evi-dence suggests that vascular dysfunction due to endothe-lial cell injury may have a pathogenic role in the occur-rence and development of AD.Malfunction of the blood-brain barrier caused by endothelial cell dysfunction is associated with the accumulation of several neurotoxic molecules within brain parenchyma,a reduction in cerebral blood flow,amyloid-β transfer and hypoxia,especially at the early stages of the disease.At the same time,it can-not be ignored that the peripheral arterial vascular endo-thelial cell dysfunction also seems to be closely related to the risk and the severity of symptoms of AD.Some mole-cules are thought to be messengers connecting the central and peripheral endothelial cells.Peripheral and central vascular endothelial cells communicate with each other and influence the progression of AD through some common mechanisms.In this review,we provide an ap-praisal of the endothelial cell dysfunction in cerebral and systemic vasculature,and give the evidence that vascular pathology is inextricably linked to disease onset and pro-gression of AD.
ABSTRACT
Objective To investigate the methods of diagnosis and treatment of acute lower gastrointestinal massive bleeding. Methods Retrospective analysis was made on diagnozing and treating of 21 patients with acute lower gastrointestinal massive bleeding Results Within a total of 21 cases,bleeding was controlled by conservative treatment in 6 cases(28.6%),supermesenteric angiography showe positive findings in 92.8% and the interventional therapy was applied successfully in 84.6%. no recurrence was observed after Ⅰ month to 4 year follow up. Conclusions Patients with acute lower gastrointestinal massive bleeding should be treated firstly by conservatie method,uncontrollable bleeding should be evaluated by selective supermesenteric angiography;after the bleeding artery was recongnized by angiography,the intervention embolotherapy should be taken;the patients whose angiography are negative and bleeding cannot be controlled should be operatded
