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 METHODS:Through retrospectively analyzing drug advertisements permission number of which had been revoked issued by China Food and Drug Administration during Jan. 2013-Jun. 2015 statistically,the reasons for permission withdrawal were analyzed to put forward the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 RESULTS & CONCLUSIONS:A total of 46 items of permission number had been revoked,including 45 items of Chinese patent medicine (97.83%),1 item of western medicine (2.17%).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 study the association between renal dysfunction and platelet parameters in elderly patients with early heart failure (HF).Methods 637 patients (350 old-aged and 287 middle-aged) with hypertension,CHD,T2DM admitted to our hospital from January 2013 to December 2014 served as a disease group and 464 subjects (229 old-aged and 235 middle-aged) selected from the 973 Aging Project in September 2007-June 2008 served as a healthy group.Their eGFR and platelets (PLT) were calculated,their plateletcrit (PCT) and mean platelet volume (MPV) were measured.Association between platelet parameters and renal dysfunction was analyzed by binary logistic regression analysis.Results The MPV and PCT were significantly lower in the old-aged disease group than in the old aged healthy group (9.78± 1.45 vs 10.66±0.78,P＜0.01;19.79 ± 6.21 vs 21.82 ± 6.04,P＜0.01).The PLT and PCT were closely associated with the eGFR in two groups (P＜0.05,P＜0.01).Binary logistic regression analysis indicated that the median and high PLT in disease group and the median PLT in healthy group were independently associated with renal dysfunction (OR=0.560,95％CI:0.315-0.996;OR=0.480,95％CI:0.262-0.879;OR=0.483,95％CI:0.249-0.936,P＜0.05).Conclusion Attention should be paid to the effect of PLT and their functional activity on renal function in treatment of early HF patients because aging-induced change of PLT and their functional activity are associated with renal dysfunction.

Objective:To evaluate the effects of magnetic attachment keepers on MRI images.Me-thods:In in vitro part,keepers of MAGFIT EX 400,MAGFIT EX 600 and MAGNEDISC 800 magnetic attachment systems were cast into standard root-caps with different alloy respectively,including nickel-chromium alloy and gold-palladium alloy,or not be cast for contrast.In in vivo part,volunteers with keepers in different position and amount were included.All the specimens and volunteers were imaged by a Siemens SONATA 1.5-T MRI scanner.Extent of the artifacts in every slice was measured.The magnitude of the artifacts and the distortion of the anatomic structures were compared.Results:All kinds of keepers being studied produced obvious MRI artifacts.The extent of MRI artifacts induced by MAGFIT EX 400 keepers,MAGFIT EX 600 keepers and MAGNEDISC 800 keepers are 158.94 mm,168.52 mm and 173.00 mm,respectively.The images of mental region,tongue,palate,jawbone and sinus were evidently obscured by artifacts in all cases.When keeper was put in the molar region,the keeper-related MRI artifact may obscure the imaging of brain,spinal cord.SE sequence with right-left frequency-encoding direction was more desirable in MRI for the patients with magnetic attachment keepers.Conclusion:Keepers of magnetic attachment system did induce obvious artifacts in MRI examination.

Objective To study the pro-invasive effect of irradiation on human glioblastoma cell line U87 and its possible mechanism.Methods Cultured U87 cells received different doses of irradiation (0,2,and 4 Gy).The change in cellular invasiveness was measured using the real-time cell analyzer system.The activities of matrix metalloproteinase-2 (MMP2) and matrix metalloproteinase-9 (MMP9) in U87 ceils were measured by gelatin zymography before and after irradiation.The content and distribution of intracellular β-catenin after irradiation were determined by immunohistochemistry.The mRNA levels of Wnt/β-catenin target genes were measured by real-time quantitative PCR.Results After irradiation,the invasiveness of U87 cells increased significantly (P ＜ 0.01),which was dose-dependent within a certain dose range; the activities of MMP2 and MMP9 in U87 cells increased significantly (P =0.031 for MMP2 ; P =0.004 for MMP9) ;the content of β-catenin in U87 cells increased significantly (P ＜ 0.01),with translocation from the cell membrane and adherens junctions to the nucleus; the mRNA levels of Wnt/β-catenin-related genes (FZD7 and TCF1) increased significantly (P ＜ 0.01),and the transcription of Wnt/β-catenin target genes,especially those related to migration and invasion such as MMP2,MMP7,MMP9,and CD44,was significantly enhanced (P ＜ 0.05).Conclusions Irradiation can promote the invasion of glioblastoma U87 cells,possibly by activating the Wnt/β-catenin pathway and enhancing the transcription of migration-and invasion-related genes.

Objective To investigate the characteristics of cognitive impairment in patients with type 2 diabetes mellitus (T2DM),and to analyze the correlation of T2DM with its risk factors and serum insulin like growth factor-1 (IGF-1) levels Methods A total of 78 hospitalized patients with T2DM at our hospital from November 2011 to March 2012 were divided into the cognitive impairment group (n=39) and the non-cognitive impairment group (n=39) according to Montreal Cognitive Assessment (MoCA) scores,and general clinical data were collected.Levels of blood lipids,glycosylated hemoglobin (HbAlc),fasting blood glucose (FBG),fasting blood insulin (FBI) and other biochemical indicators were detected,insulin resistance index (HOMA-IR) scores were calculated,and serum IGF-1 levels were determined by the enzyme-linked immunosorbent assay (ELISA).Results The education levle was (8.94±4.13) years for the cognitive impairment group and (12.65[2.50) years for the non-cognitive impairment group,and there was a statistically significant difference between the two groups (P=0.004).HbAlc levels were (9.69 ± 1.25) and (7.96 ± 1.31) for the cognitive impairment group and the non-cognitive impairment group,respectively,and were statistically difference between the two groups (P =0.001).Serum IGF-1 levels were (122.60±11.56) mmol/L and (139.32±9.57) mmol/L in the cognitive impairment group and the non-cognitive impairment group,respectively,and had a statistically significant difference between the two groups (P =0.037).Additionally,compared with the non-cognitive impairment group,scores on visuospatial ability,naming,language,abstraction,delayed recall and orientation were lower in the cognitive impairment group (P＜[0.05 or 0.01).Moreover,MoCA scores were negatively correlated with TC,LDL-C,TG,HbAlc,FBI levels and HOMA IR (r=0.498,-0.411,0.414,-0.452,-0.449,-0.539,respectively,P＜0.05 for all),and positively correlated with education lcvcl and IGF 1 level (r=0.579 and 0.491,respectively,P＜0.05 for both) Conclusions Cognitive impairment caused by T2DM is prominent in visuospatial ability,language,memory and executive functions,and is closely related to poor education,poor glycemic control,dyslipidemia and insulin resistance.Furthermore,decreased serum IGF-1 levels might be a risk factor for diabetic cognitive impairment.

To determine the number average molecular mass of chitosan-oligosaccharide by u-sing the acetylacetone's method based on the color-producing reaction with amino terminal . Via the tests on the repetitiveness, accuracy and the stability, supposed this method was reliable. At the same time, the contrastive results of HPLC and the traditional K3Fe(CN)6 method indicate that the acetylacetone method was more suitable for the determination of chitosan-oligosaccharide molecular mass.

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.

Serum levels of CXC chemokine ligand 10 (CXCL10) and chemokine receptor 3 (CXCR3) were determined in 50 patients with type 1 diabetes mellitus (T1 DM) and 30 normal control subjects by ELISA method.The results showed that serum levels of CXCL10 and CXCR3 in T1DM patients were significantly higher than those in normal subjects [(258.17 ± 39.12 vs 96.47 ± 26.91) ng/L,(851.87 ± 70.04 vs 441.82 ± 72.24) pg/ml,both P＜0.05].Serum level of CXCL10 in patients dropped sequentially with durations of diabetes ＜6 weeks,≥6 weeks or ＜3 years,and ≥ 3 years,being statistically significant between groups (P＜0.05).These results suggest that serum levels of CXC10 and CXCR3 may reflect the immune activity in T1DM.

Objective This study aimed to explore the clinical characteristics and treatment of congenital central hypoventilation syndrome(CCHS),to raise awareness on the CCHS for early diagnosis and treatment.Methods The clinical data of 4 babies with CCHS were analyzed,all of the babies were repeated bruising,hypercapnia,and difficult-to-wean.After the relevant checks,we precluded the primary diseases of heart,lung and neuromuscular dysfunction that lead to low ventilation,and detected the major pathogenic genes,Phox2b of CCHS,refer to literature and diagnostic criteria of CCHS.Results Four babies all had typical clinical features of CCHS:enough ventilation when awake.But when they were asleep,their respiratory rate slowed down,hypoventilation,cyanosis and hypercapnia appeared,and they can not be awaked by hypercapnia and hypoxemia caused by hypoventilation.Genetic testing confirmed the presence of Phox2b mutations.Two infants were supported by non-invasive biphasic positive airway pressure(BiPAP),an infant was discharged home at 3 months of age with non-invasive BiPAP,and an infant was discharged home at 1 month of age.Both of them were monitored and treated at home,and showed normal development.Conclusion For babies who were repeated bruising,hypercapnia,and difficult-to-wean,but no primary diseases of heart,lung and neuromuscular dysfunction that lead to low ventilation,CCHS must be considered.Genetic testing of Phox2b can be used as an important diagnostic tool,and non-invasive BiPAP is one of the efficacious methods in the treatment of CCHS.
