Autophagy is a powerful process for removing such proteins and for maintaining homeostasis.However,autophagy dysfunction has also been implicated in the pathogenesis of vari-ous neurodegenerative diseases,including Parkinson 's disease (PD).Recent studies have shown that TFEB could regulate au-tophagy and lysosome function through regulating the expressionof the relatedgenes.Thus,TFEB plays a key role in the occur-rence of Parkinson's disease.Therefore,this article will make a review of the regulatory mechanism of TFEB and its role in Par-kinson's disease.

Objective:To understand the cognition and training status of basic life support among medical staff in Linfen, Shanxi Province, and to provide reference for the development of targeted training strategies and programs.Methods:A questionnaire survey was conducted among medical staff in 12 county hospitals in Linfen, Shanxi Province by convenience sampling method. The survey included the general characteristics of departments and medical staff, previous basic life support training assessment and cognitive status.Results:A total of 839 medical staff were included, 756 (90.1%) completed the survey, 183 (24.2%) were doctors and 573 (75.8%) were nurses. Most personnel lacked awareness of environmental safety, emergency response system start-up, adequate compression, airway management, and electrical defibrillation.Conclusions:The cognitive status of basic life support of medical staff in Linfen county is not optimistic. It is necessary to construct an applicable precision training course and retraining assessment system to improve the cognitive level and practical operation ability.

OBJECTIVE To establish the fingerprint of Pinghuo tea standard decoction and a method for determination of multi-component to clarify the transfer relationship of quantities and quality from pieces and standard decoction. METHODS Fifteen batches of Pinghuo tea standard decoction were prepared and the extract rate was determined； the fingerprint of the preparation was established by using high-performance liquid chromatography（HPLC）； the similarity evaluation and the determination of common peaks were performed， and chemometric analysis was performed； the same method was used to determine the content of indicator components and the transfer rate was calculated. The chromatographic column was Venusil C18 column with mobile phase consisted of acetonitrile-0.1% phosphoric acid solution （gradient elution）； the column temperature was 30 ℃， and the detection wavelengths were 238 nm （0-37 min， 85-102 min） and 330 nm （37-85 min） at a flow rate of 1.0 mL/min with an injection volume of 10 μL. RESULTS The similarity of HPLC fingerprints for 15 batches of Pinghuo tea standard decoction was not lower than 0.968. A total of 24 common peaks were calibrated and 9 peaks were recognized， which were as follows neochlorogenic acid （peak 3）， chlorogenic acid （peak 6）， geniposide （peak 9）， glycyrrhizin （peak 10）， galuteolin （peak 11）， isochlorogenic acid A （peak 14）， luteolin （peak 21）， kaempferol （peak 23） and glycyrrhizic acid （peak 24）. Cluster analysis， principal component analysis and orthogonal partial least squares discriminant analysis showed consistent results， all of which could classify the 15 batches of samples into three categories. The linear range of indicator components in 15 batches of Pinghuo tea standard decoction， such as geniposide， luteolin， isochlorogenic acid A， glycyrrhizin， and glycyrrhizic acid， were 0.020 580-0.411 600， 0.001 617-0.080 850， 0.006 076-0.607 600， 0.005 125-0.071 740， and 0.017 288-0.432 200 mg/mL， respectively； RSDs of precision， repeatability， stability and recovery rate tests were all not higher than 4% （n＝6）. The mass fractions ranged 3.227 9-10.002 2， 0.297 4-0.554 6， 3.350 1-6.159 6， 0.720 6-1.073 3， 2.003 1-3.030 1 mg/g； transfer rates from the pieces and standard decoction were 19.762 8%-35.840 5%， 12.123 3%-21.254 0%， 46.097 2%-82.869 4%， 58.708 8%-91.629 6%， 39.114 3%-63.710 6%. The transfer rates of the extract from 15 batches of Pinghuo tea standard decoction ranged from 61.15%-84.68%. CONCLUSIONS Established HPLC fingerprint and content determination methods in this study are simple and accurate， which can provide reference for the quantitative value transfer study， quality control， clinical application and the development of subsequent formulations of Pinghuo tea standard decoction.
