China Pharmacy 2017;28(16):2281-2283
OBJECTIVE:To compare the licensed pharmacist system in China and the USA,and to provide reference for im-proving pharmaceutical care and promoting public safety of drug use in China. METHODS:The relevant literatures in recent 10 years were retrieved from CJFD and Wanfang database. The differences of legal status,access qualification,legal obligations and responsibilities of licensed pharmacists in the USA and China were compared,and suggestions on improving the licensed pharma-cists system in China were put forward. RESULTS & CONCLUSIONS:At present,the problems of licensed pharmacist system in China are mainly that the legal status is not high,the access threshold is low,the legal obligations and responsibilities are not clear. However,the licensed pharmacist system in the USA has been developed for a century and formed a relatively strict legal sys-tem. Model State Pharmacy Act promulgated by National Association of Boards of Pharmacy in USA has clearly defined the access qualifications,legal obligations and responsibilities of licensed pharmacists. The pharmacy acts of the states were enacted on its blueprint. In view of current problems in China,it is necessary to learn from the above experience of the USA to improve the legal status,access qualification,legal obligations and responsibilities of licensed pharmacists and the quality of pharmaceutical care.

Objective To investigate the effect of penehyclidine (PHCD) pretreatment on Toll-like receptor 4 (TLR4) mRNA expression in the lung following acute lung injury (ALI) induced by hemorrhagic shock in rats. Methods Forty healthy SD rats of both sexes weighing 200-250 g were randomly divided into 5 groups( n = 8 each): group Ⅰ sham operation (group S); group Ⅱ ALI (group ALI); group Ⅲ, Ⅴ, PHCD 0.3,1.0, 3.0 mg/kg were given iv respectively at 30 min before hemorrhagic shock (P1-3). Hemorrhagic shock was induced by exsanguinations. MAP was maintained at 35-45 mm Hg for 60 min. The animals were killed at 4 h after resuscitation. Their lungs were removed for microscopic examination, W/D lung weight ratio and determination of TLR4 mRNA expression in the lung tissue (by RT-PCR). NF-κB p65 protein expression in the lung tissue was determined (by immuno-histochemical staining). Results Hemorrhagic shock significantly increased TLR4 mRNA and NF-κB p65 protein expression in the lung tissue and W/D lung weight ratio. Pretreatment with PHCD 1.0 or 3.0 mg/kg significantly inhibited hemorrhagic shock-induced increase in TLR4 mRNA and NF-κB p65 protein expression in the lung and W/D lung weight ratio. The lung injury was significantly ameliorated in group P2,3 as compared to group ALI. Conclusion PHCD pretreatment can attenuate ALI induced by hemorrhagic shock through down-regulation of TLR4 mRNA expression and decreasing NF-κB activity in the lung.

ObjectiveTo observe the protective effect of tetrahydroxystilbene glucoside (TSG) on rats' hippocampal neuronal damage induced by glutamate (Glu) in the culture.MethodsHippocampus was isolated from newborn SD rats and dispersedly cultured in the medium for 9 days. Neurons were incubated with TSG (5—100μmol/L) for 24h, the cells were washed twice with Lock's solution without Mg2+,then Glu 500 μmol/L was added. Thirty min later, the reaction was terminated by washing the monolayer cells twice with the Lock's solution and then cultures were kept at 37℃ for 24h. Cell viability was measured by MTT method and cell membrane damage was determined by LDH leakage; with Fluo-3/AM as an intracellular calcium indicator and added into the bathing medium, fluorescent intensity of intracellular free calcium were observed through laser scanning confocal microscopy (LSCM).ResultsAfter the treatment with 5—100μmol/L TSG for 24h, the decrease of cell viability and the increase of LDH leakage caused by Glu was obviously resisted dose dependently. TSG inhibited increase of Ca2+ in cytoplasm, compared with model group.ConclusionTSG can significantly promote the cell viability and reduce the cell membrane damage in Glu treating hippocampal neurons. The neuroprotective activities of TGS is mediated by inhibiting Ca2+ overload in cytoplasm.

Objective To obtain more information concerning polymorphism of the thyrotropin (TSHR) in Graves diseases(GD). Methods (1)A family of GD was studied (including 3 patients and 9 healthy family members)to examine SNPs of TSHR through direct sequencing of all 10 exons and part of introns. (2)In the current case-control study, 30 patients with familiar GD, 48 sporadic patients and 96 healthy control individuals were used to assess whether SNP of TSHR was associated with GD. Genomic DNA was extracted from peripheral leukocytes isolated from ACD-anticoagulated blood. Ten exons were amplified by PCR, using primers designed by ourselves. After purifying, the products were sequenced. Results Eight polymorphisms were found. There was a novel polymorphism in exon 8. There were no significant differences between patients and controls. Conclusions These findings suggested that the novel and other polymorphisms of the TSHR gene may not be responsible for GD. There are racial differences in the distribution of polymorphisms of TSHR gene.

Objective To explore the therapeutic effect of phenylethanoid glycosides on cyclophosphamide (CTX)-induced dyszoospermia in mice and to preliminary elucidate the mechanisms involved in the process. Methods Phenylethanoid glycoside was extracted by ethanol extraction.Forty male BALB/C mice were randomly divided into control group,model group,low dose of phenylethanoid glycosides group (50 mg· kg-1 )and high dose of phenylethanoid glycosides group (100 mg·kg-1 ).Except control group,the dyszoospermia mouse model was established by peritoneal injection of CTX at the daily dose of 80 mg· kg-1 ,once daily for successive 5 d. After modeling, phenylethanoid glycosides were intragastrically administered at corresponding doses to each phenylethanoid glycosides group.Equal volume of normal saline was given to the mice in control group and model group by gastrogavage.All the medication was performed once daily for successive 30 d.The testis tissue was obtained 24 h after the last intragastric administration.The level of testosterone in the testis tissue homogenate was determined by enzyme linked immunosorbent assay.The sperm counts, the motility rates, and the teratospermia rates in various groups were compared.The morphological changes of the testis tissue were observed using HE staining.Results Compared with control group, the sperm count and the motility rate were decreased, the teratospermia rate was increased,and the testosterone level in the testis tissue homogenate was decreased in model group(P<0.01).Compared with model group,the sperm counts and the motility rates were increased,the teratospermia rates were decreased, and the testosterore levels in the testis tissue homogenate were increased in phenylethanoid glycosides groups (P<0.05 or P<0.01).The histological results showed atrophy and degeneration of seminiferous tuble,thicker seminiferous epithelium and azoospermic lumina in model group;the number of seminiferous epithelial layers was increased and the seminiferous cells orderly arranged, and many sperms were found in the tubules in phenylethanoid glycosides groups.Conclusion Phenylethanoid glycosides has obviously therapeutical effect on CTX-induced dyszoospermia in mice,and its mechanisms might be correlated with recovering the testosterone level.
