OBJECTIVE:To investigate the composition and medication regularities of prescriptions for Treatise on Febrile Dis-eases. METHODS:The prescriptions included in Treatise on Febrile Diseases were collected and inputted into TCM inheritance platform system(V2.5)software,and prescription database was established. The medication and the compatibility regularity of pre-scriptions were excavated using the function of software integration. RESULTS & CONCLUSIONS:83 kinds of TCM involved in 112 prescriptions ranked by frequency,among which 24 ingredients were used more than 4 times. Commonly used TCM groups were summarized to evolve 16 key groups and 8 new prescriptions. Four properties of TCM are mainly the property of“Wen and Han”,and five tastes mostly are“Sweet,Bitter,Spicy”. TCM with the property of“Wen and Sweet”taste are more than those with the property of“Wen and Spicy”,and TCM acting on spleen are more than those acting on lung.

Parkinson′s disease (PD) is the most common age-related neurodegenerative disease, which has the effects on the patients′ quality of life and brings a huge burden to the society and family. The pathological feature of PD is the abnormal accumulation of alpha-synuclein (α-syn) in the brain of substantia nigra-striatum, mediating the death of dopaminergic neurons. However, further studies have found that α-syn mediates the abnormal function of astrocytes leading to the destruction of the blood-brain barrier and the release of inflammatory factors caused by microglia, which are related to the pathogenesis of PD. Therefore, neurons, glial cells, and blood vessels as a whole named neurovascular unit can better reflect the pathophysiological environment of PD and reveal the PD pathogenesis. Studies have detected the ways of α-syn transmission, such as prion-like, tunneling nanotubes, exosomes, are connected with the pathogenesis and progression of PD. The Braak stage and the prospective cohort of early PD provide a view that the peripheral α-syn to the central nervous system may be an another important way to mediate the pathogenesis and progression of PD. The research about the abnormal aggregation and spread of α-syn can provide the new theory for the pathogenesis of PD and the new disease modifying therapy of PD. This article reviews the role of abnormal aggregation and transmission of α-syn in the pathogenesis of PD.

Objective To explore the improvement of cognitive impairment in patients with mild and moderate vascular cognitive impairment( VCI) treated with cerebralcare granule ( CG) and basic treat-ment.Methods From October in 2014 to December in 2016 year,143 cases of VCI patients were admitted from six hospitals in some areas of Hebei Province as the research objects,and divided into CG treatment group (experimental group,n=98) and conventional treatment group (control group,n=66).Three months and six months after treatment,the score of mental state examination ( MMSE) ,the Montreal cognitive assess-ment scale ( MoCA) and the daily living capacity scale( ADL) of the two groups were compared after 3 and 6 moths of treatment.Results ①The total score of MMSE in the experimental group was higher than that of the control group for six months after treatment, and the difference was statistically significant ( ( 23. 76 ± 4.02) vs (21.52±5.13),P<0.05).②Six months after treatment,the total score of MoCA ((21.06±4.66) vs (18.32±5.20)) and visual spatial/executive function((3.05±1.37) vs (2.42±1.66)),calculation force ((2.24±0.84) vs (1.83±1.05)) and orientation ability((5.20±1.12) vs (4.06±1.35)) scores in the ex-perimental group were significantly higher than those in the control group (P<0.05) .③Six months after treat-ment,the ADL score in the experimental group was lower than that before treatment,and the difference was statistically significant((24.96±8.74) vs (29.20±11.55),P<0.05);while there was no significant difference in the ADL score between the experimental group and the control group after 6 months (P>0.05).Conclusion CG can improve cognitive function in mild to moderate VCI patients,mainly in visual space/execution func-tion,calculation ability and orientation ability,and with the extension of treatment time,the curative effect is more obvious.
