China Pharmacy 2016;27(10):1435-1437
OBJECTIVE:To explore the necessity of pharmaceutical care provided by clinical pharmacists during the use of ad-vertised drugs. METHODS:Through retrospectively analyzing drug advertisements permission number of which had been revoked issued by China Food and Drug Administration during Jan. 2013-Jun. 2015 statistically,the reasons for permission withdrawal were analyzed to put forward the focal point of pharmaceutical care development. RESULTS & CONCLUSIONS:A total of 46 items of permission number had been revoked,including 45 items of Chinese patent medicine (97.83%),1 item of western medicine (2.17%). The reasons for permission revoking mainly included overstating therapeutic efficacy without authorization,guaranteeing onset time,guaranteeing recovery in certain time,propagandizing drugs in the name of experts,etc. These drug advertisements sent relatively one-sided information so as to easily mislead patients and consumers to use drug irrationally. So,it is necessary to provide pharmaceutical care by clinical pharmacists about this kind of drug. The focal points of pharmaceutical care contain telling patients usage and dosage detailedly,and explaining possible ADR and relevant countermeasures;emphasizing different therapeutic efficacy,onset time and recovery time due to individual difference;strengthening prescription check and medication suitability ap-praisal,and so on.

ObjectiveTo investigate the effect of soluble β-amyloid protein (Aβ) oligomers on the expression levels of insulin signaling transduction cascades-associated proteins including insulin receptor ( InsR),insulin receptor substrate-Ⅰ( IRS-Ⅰ) and protein kinase B (PKB) of rat hippocampal neurons,and the pathogenesis of Alzheimer's disease (AD) in depth.MethodsSoluble Aβ oligomers (5 μl) were injected into the lateral ventriculus of the AD group by a microinjector under the stereotaxic apparatus.Normal saline solution ( NS,5 μl) was injected into the NS group in the same way,and the control group received the puncture without injection. It was repeated after 1 week and the behavior of all rats was evaluatedbyY-mazetestafter2weeks.Thenhippocampuswasremovedandunderwent immunohistochemical staining to detect the expression of proteins associated.ResultsCompared with the other groups,learning and memory ability of the Aβ-treated rats were impaired.To be specific,the times of learning were increased and the times of memory were decreased. However,there was no significant difference between the NS group and the control group.Besides,the expression levels of InsR,IRS-Ⅰ,and PKB were decreased in AD group showing that a mean optical density of staining on these proteins ( InsR:0.12 ± 0.0l ; IRS-Ⅰ:0.14 ± 0.02; PKB:0.12 ± 0.03 ) was reduced in contrast with that in the NS group and the control group.Whereas there was no significant difference between the NS group (0.40 ± 0.02,0.39 ± 0.06,0.38 ± 0.03,mean difference:- 0.13,- 0.13,- 0.17,all P < 0.05 ) and the control group (0.38 ± 0.07,0.35 ± 0.03,0.35 ± 0.06,mean difference:- 0.15,- 0.07,- 0.73,all P < 0.05 ).ConclusionsSoluble Aβ1-42 induced learning and memory disability of the rats.The mechanism might be that Aβ can lead to disorders of the insulin signaling transduction pathway of hippocampal neurons and decrease the expression levels of the proteins in the pathway.

Objective: To prepare and characterize the polyclonal antibody against KIAA0649 and identify the localization and the functional motif of KIAA0649. Methods: Three polypeptides were synthesized based on the bioinformatics analysis of KIAA0649 protein. New Zealand rabbits were immunized with the mixture of the three KIAA0649 peptides coupled with keyhole limpet hemocyanin ( KLH). The titer of the antisera was detected with ELISA. The antisera were purified with immuno-affinity chromatography when the titer reached 1:10~5. Western blot was performed with the purified antisera on the cell lysates of U2OS cells transfected with either Flag-KIAA0649 or KIAA0649-targeting siRNA. Immunofluorescence was performed with the purified antisera and anti-Flag antibody on the cells transfected with FlagKIAA0649. A series of Flag-K1AA0649 deletion mutants was constructed by PCR cloning. The cellular compartmentation of full-length Flag-KIAA0649 and its deletion mutants were analyzed with immunofluorescence. Results: The results of Western blot and immunofluorescence demonstrated that the antisera from the KIAA0649 polypeptides-immunized rabbits specifically recognized endogenous and exogenous KIAA0649. The full-length Flag-K1AA0649 displayed specific nuclear foci. The Flag-KIAA0649 deletion mutant containing PENF motif showed the same nuclear foci as the full length of Flag-KJAA0649, suggesting that the PENF motif could be the minimum functional motif of KIAA0649. Conclusion: We have obtained anti-KIAA0649 polyclonal antibody which will be useful for further investigation. The PENF motifcould be the minimum functional domain of KIAA0649.

Objective To investigate the effects of estrogen on mismatch repiar gene expression in colonic mucosa in vivo. Methods A total of 42 healthy individuals underwent colonoscopy were enrolled in the study. Half an hour before colonoscopy examination, blood sample was taken for determining the serum estradiol (E2) level. N ormal colonic mucosal tissues determined by naked eye under colonoscopy examination were taken in the right hemi colon to detect HMLH1 and hMSH2 gene expression by semi-quantitative RT-PCR and immunohistochemistry staining. Then the correlation of serum E2 levels with hMLH1 and hMSH2 expression in colonic mucosa was analyzed. Results A bimodal curve was presented for the correlation between serum E2 level in healthy individuals and hMLH1 expression in colonic mucosa. A strong positive correlation of E2 level with hMLH1 expression in normal colonic mucosa was observed when serum E2 level was more than 45 pg/ml (For mRNA, P=0. 003, r=0. 701; for immunohistochemistry positivity index, P=0. 000, r=0. 874).However there was no correlation between E2 level and hMSH2 expression. Conclusion High serum E2 level might increase the hMLH1 gene expression in colonic mucosa in vivo.
