China Pharmacy 2016;27(30):4197-4199
OBJECTIVE:To explore consumers’perceptions for pharmaceutical care by community pharmacist when purchas-ing OTC drugs. METHODS:Semi-structured interview was conducted for 100 consumers who were recruited in Xingqing District, Jinfeng District and Xixia District of Yinchuan,Ningxia Hui Autonomous Region,their expection for pharmaceutical care by com-munity pharmacists was summarized. RESULTS:Totally 100 residents were interriewed,and 97 completed a full interview with ef-fective interview rate of 97%. Consumers still did not clearly on distinguishing the OTC drugs. The majority of consumers chosen OTC drugs were based on experience and brand,a handful of consumers were under the guidance of community pharmacists. Con-sumers were most concerned about the efficacy,adverse reactions and drug quality in using OTC drugs. Most consumers were not satisfied with the pharmaceutical care in purchasing OTC drugs. Nevertheless,due to a lack of medicine knowledge,consumer had a great demand for pharmaceutical care and willingness to accept it. Low professional level of community pharmacist and staff in current community pharmacy and lack of effective communication between pharmacist and consumer were the obstacles of develop-ing pharmaceutical care. CONCLUSIONS:Because of their distrust on competence of community pharmacist,consumers seek less pharmaceutical care of OTC drugs at community pharmacy though they had expectations on pharmaceutical care of OTC drugs by community pharmacist. Consumers’rely on self-choice of drugs make them exposed to more drug risks.

Objective To explore the mechanisms of recovery from aphasia by using speech-activated single photon emission computed tomography(SPECT)brain imaging.Methods The SPECT brain imaging of 7 aphasic patients caused by various brain disorders were performed while they were at rest and performing oral reading,respec- tively,with an one-day interval.A semi-quantitative analysis of regional cerebral blood flow(rCBF)was conducted using region of interesting(ROI).The change of rCBF before and after reading was calculated and compared to ana- lyze the role of both hemispheres in the recovery from aphasia.Results It was found that the activation pattern of brain region was associated with the speech performance of the patients.The activated brain regions were mainly loca- ted at the left hemisphere in 5 patients whose reading capacity was relatively better,and mainly at the right hemi- sphere in the other 2 patients who had poor performance in reading.Conclusion After a focal lesion of the left hemisphere,the recovery of speech function might be mainly attributed to the repair of the damaged left hemisphere language network.When the left-hemispheric centers were permanently impaired,the brain would recruit some right- hemisphere regions for speech processing,but this strategy was less effective than the repair of the original speech-rel- evant network.

This study was aimed to investigate the protective effect of catalpol against high glucose induced injury on vascular endothelial cells (ECV-304). ECV-304 cells were culturedin vitro. MTT method was applied to detect cell viability. NO and LDH level were measured by spectrophotometer method. The effect of catalpol against high glucose induced injury on ECV-304 was observed. The results showed that there were no obvious changes in cell viabilities of ECV-304 cultured in normal concentration of glucose medium among groups with different concentrations of catalpol. Compared with the control group, cell viability was significantly decreased (P< 0.01), the NO secretion was significantly reduced (P< 0.01), the LDH level was increased obviously (P< 0.01) in the high glucose (30 mmol·L-1 glucose) injury model group. The high osmotic (24.5 mmol·L-1 mannitol) group was set up as a positive control. Comparison between the low dose (1 ng·μL-1 catalpol + 30 mmol·L-1 glucose), middle dose (10 ng·μL-1 catalpol+ 30 mmol·L-1 glucose), and high glucose (30 mmol·L-1 glucose) injury model group showed no changes on cell viability and NO (P> 0.05); while the LDH level was reduced (P< 0.01). Comparison between the high dose catalpol (100 ng·μL-1 catalpol + 30 mmol·L-1 glucose) group and the high glucose model group showed that the cell viability was obviously increased (P< 0.01); NO secretion was increased (P< 0.05); and the LDH level was obviously reduced (P< 0.01). It was concluded that catalpol had protective effect against high glucose induced ECV-304 injury through the regulation of NO and LDH level. The effect of high dose was obvious.
