OBJECTIVE:To better carry out the pharmaceutical services in outpatient pharmacy,and provide reference for the safe,effective and rational drug use of outpatients. METHODS:Questionnaires were designed based on the related information pro-vided by consultation services of outpatient pharmacy in our hospital and referring to the related literatures to randomly select and investigate the patients of outpatient pharmacy in our hospital,and the results were statistically analyzed. RESULTS:There were to-tally 450 questionnaires,involving 417 valid questionnaires with the effective recovery of 92.67%. The questions about pharmaceuti-cal service of surveyed patients were dosage and precautions,respectively with the number of 254(60.91%)and 251(60.19%);followed by functions and indications,with the number of 234 (56.12%);besides,there were also with widespread concerns, such as drugs efficacy,medication time,and medication of elderly,children and pregnant women,etc. Among the surveyed pa-tients,20.75% were blind medication;89.45% thought the pharmacists’guidance was helpful for medication;there were still 21.35% without pharmacists’medication guidance. CONCLUSIONS:The survey shows the poor awareness of rational drug use and lacking knowledge of drugs in outpatients,they are eager for medication guidance from professional pharmacists. However,the pharmaceutical service in outpatient pharmacy needs to be improved. It is suggested to actively promote the pharmacy services by implementing points medication,adopting red and blue for warning labels,providing comprehensive drug counseling services and carrying out rational drug use education,etc.

Impulsive control disorders (ICD), as a special non-motor symptom of PD, have been widely recognized with the in-depth research on non-motor symptoms of Parkinson's disease (PD) in recent years. ICD refers to repetitive and excessive activities that are not able to resist impulse, desire drive or temptation in order to obtain pleasure regardless of the adverse consequences. Impulse control disorders are common in people with Parkinson's disease. The pathogenesis of PD combined with ICD is still unclear and may involve the joint action of multiple factors. This paper will review the epidemiology, etiology and risk factors, genetic characteristics, imaging characteristics, diagnosis and treatment of PD patients with ICD, aiming to provide a new direction for clinical early diagnosis and individualized treatment of PD patients with ICD.

Parkinson′s disease (PD) is a neurodegenerative disease commonly found in middle-aged and elderly people. It is characterized by resting tremor, bradykinesia, myotonia, and abnormal posture gait. The main pathological changes were the loss of dopaminergic neurons in the substantia nigra and the formation of Lewy bodies in the cytoplasm of the residual neurons. The main component of the Lewy bodies was α-synuclein. And why it causes the degeneration of dopaminergic neurons in the substantia nigra is not known. At present, most studies on Parkinson′s disease focus on the pathogenesis of the disease. More and more evidence shows that respiratory chain injury is a key feature of sporadic PD patients, and the proteins encoded by PD-related genes are related to the disorder of mitochondrial function. We believe that the important mechanism of the disease is impaired mitochondrial function due to environmental and (or) genetic inheritance. This article highlights new advances in mitochondrial dysfunction in Parkinson′s pathogenesis, including mitochondria and cell-mediated immunity, endoplasmic reticulum (ER)-mitochondrial axis, sirtuin-mediated mitochondrial stress response, and the role of microRNA in the etiology of PD. A deeper understanding of these mechanisms may provide inspiration for the development of new targeted therapies.

Parkinson′s disease (PD) is the second most common neurodegenerative disease in middle-aged and elderly people. In addition to motor symptoms, PD also has many non motor symptoms, such as dysosmia, constipation, cognitive impairment, etc. Among them, dysosmia is a common non motor symptom of early Parkinson′s disease. Research has confirmed that olfactory dysfunction (OD) can appear before the typical clinical symptoms of PD, which is of great significance to the diagnosis and treatment of diseases. However, at present, the pathogenesis of OD is still unclear, and the inspection methods have not been unified, and there is no complete cure. This article reviews the latest research progress of dysosmia in Parkinson′s disease.

OBJECTIVE： To study the mechanism of Prunus persica-Carthamus tinctorius couplet medicine in the treatment of osteonecrosis of the femoral head （ONFH）. METHODS： The network pharmacology was adopted. The active components of P. persica -C. tinctorius couplet medicine and ONFH target were screened through TCM systematic pharmacological analysis platform target （TCMSP）， DRAR-CPI， hnuman gene database （GeneCards） and online medelian inheritance in man （OMIM） using oral availability of compounds （OB）＞30％ and drug like （DL）＞0.18 as standard. Network topology attribute analysis software Cytoscape 3.6.0 was utilized to construct the active components-ONFH targets network. Target protein interaction network was established on the basis of STRING database， and top 5 target proteins in the list of connectivity were screened， and molecular docking server was used to predict the combination activity of active components from P. persica -C. tinctorius couplet medicine. The biological processes of target gene ontology （GO） and metabolic pathways in Kyoto encyclopedia of genes and genomes （KEGG） were enriched and analyzed by DAVID. RESULTS： A total of 44 active components were screened from P. persica -C. tinctorius couplet medicine， including baicalin， quercetin， etc.， and 78 targets related to ONFH including VEGF， VEGI， CRP， etc. Through analysis of molecular docking server， binding activity of active components of P. persica -C. tinctorius couplet medicine to target protein was strong. GO and KEGG pathway enrichment analysis showed that biological process of P. persica -C. tinctorius couplet medicine for ONFH was related with negative regulation of apoptosis process and positive regulation of nuclear factor-κB transcription factor， mainly through regulating secretory glycoprotein signaling pathway， melanogenesis signaling pathway， VEGF signaling pathway， signaling pathway of basal cell carcinoma， adenosine-activated protein kinase signaling pathway. CONCLUSIONS： This study preliminarily validates the major targets and pathways of P. persica -C. tinctorius couplet medicine for ONFH， which lay a foundation for further study on their pharmacological action.
