Chemical Components of Traditional Chinese Medicine in Treating Alzheimer's Disease and Its Mechanism： A Review / 中国实验方剂学杂志

Alzheimer's disease （AD） is one of the most common diseases in the elderly population. Its etiology involves multiple pathogenic factors and pathological links such as abnormal deposition of β amyloid protein （Aβ）， hyperphosphorylation of Tau protein， abnormalities of the cholinergic system， oxidative stress， and inflammatory response. However， its specific pathogenesis has not been clarified， and no specific therapeutic drugs have been found. In recent years， more and more studies have paid attention to the potential of chemical components of traditional Chinese medicine （TCM） in the treatment of AD. However， the diversity and complexity of the chemical components of TCM may have a positive impact on multiple pathological links of AD. Researchers have isolated many active components from TCMs， and the effects of treating AD have been confirmed by modern pharmacological studies. Through literature analysis， this article found that the main chemical components of TCM with anti-AD effects were saponins （31%）， flavonoids （24%）， polysaccharides （20%）， lactones （8%）， alkaloids （7%）， phenols （3%）， and other compounds （7%）. Among them， ginsenoside， notoginsenoside， epimedium flavones， puerarin， baicalein， schisandra polysaccharide， angelica polysaccharide， ganoderma lucidum polysaccharide， pachyman， huperzine A， berberine， andrographolide， curcumin， emodin， and gastrodin have been extensively studied in terms of their anti-AD effects， and their mechanisms of pharmacological action have been involved in many aspects of AD pathogenesis. This article reviews the anti-AD activities and possible mechanisms of chemical components of TCM， so as to provide a reference for the development of new drugs for the prevention and treatment of AD.

Clinical application and stability of hydromorphone in an implantable imfusion system:research advances / 国际药学研究杂志

Hydromorphone(HM),appeared in the Chinese market in 2013 is a more potent opioid analgesic than morphine and is used for moderate to severe pain. Micro-invasive drug administration methods,including continuous infusion and patientcon?trolled analgesia(PCA),will provide hopes for controlling the outbreak of pain and improving patients' satisfaction. At present ,hydro?morphone is the most commonly used drug for the treatment of acute pain,chronic pain and cancer pain. However,we should also con?sider the stability and compatibility of hydromorphone in the implantable infusion system that is most commonly used in these patients. The purpose of this paper is to review the clinical application and stability(changes in color,pH and concentration)of hydromor?phone in different infusion systems so as to provide the basis of rational clinical application.

Literature Analysis of Moxifloxacin-induced Adverse Drugs Reactions in 3 445 Cases / 中国药房

OBJECTIVE:To investigate the characteristics and regularity of moxifloxacin-induced adverse drug reaction(ADR) and provide reference for the rational clinical use of drugs. METHODS:Retrieved from CNKI (2005-2014) about the moxifloxa-cin-induced ADR,3 445 cases and the related ADR information were statistically analyzed. RESULTS:Moxifloxacin-induced ADR had a certain relationship with gender,and the male had a high incidence,especially the elderly patients. ADR could appear within 10 min;the clinic features were allergic reaction,the nervous system and digestive system at most. CONCLUSIONS:Great impor-tance should be attached to ADR monitoring and rational use of drug to reduce or avoid the occurrences of moxifloxacin-induced ADR.

MODEST HYPOTHERMIA PROVENTS APOPTOSIS IN A NEONATAL RAT MODEL OF HYPOXIC-ISCHEMIC BRAINDAMAGE / 药物分析学报

Objective Recent studies in neonatal animals have shown that even slightly decreasing in brain or core temperature could ameliorate the damage resulting from hypoxic-ischemia insults. But the influence of hypothermia which had been used after the end of hypoxia-ischemia of the model hypoxia-ischemia brain damage(HIBD)was unknown. This research wanted to investigate whether hypothermia of defferent begin time after HIBD still could protect the brain in neonatal rats. Methods Pericranial temperatures were adjusted to 31 C in neonatal rats immediately or 2h after the end of hypoxia-ischemia(HI),the number of apoptosis cells in HIBD rats' brain had been counted,rat pups' storing food ability had been observed. Results Apoptosis increased obviously when rat pups were 8 days old, while hypothermia reduced apoptosis ,and postponed apoptosis expression in group that 31 C hypothermia was used immediately or 1h after the end of HI,and hypothermia improved the rat pups' storing food ability. This effect was more obviously in the group that hypothermia was used immediately after the HI than in the group that hypothermia was used 1h after the HI. But the protective effect was not clear in the group that hypothermia was used 2 h after the HI. Conclusion Hypothermia which was used within 1h after the end of HI could protect the HIBD neonatal rat pups brain, this effect was more obviously in the hypothermia be used early after the end of HI group than in the hypothermia be used late after the end of HI group.

THE CLINICAL ANALYSIS OF 32 CASES OF CHILDREN SMALL CEREBRAL ABSCESS / 西安交通大学学报(医学版)

32 cases of children small cerebral abscess di-agnosed with CT scaning are reported. The maxi-mum diameter of the enhancement area was 2. 2cm. 29 cases did not give a history of infection. In30 cases, Epileptic seizures were usually the Initialand main symptoms, but local neurological signswere usually absent. All of the cases were treatedby antibiotic therapy. The duration of the therapyin most childhood patients was 2～3 months exceptthree who were over 3 months.
