Objective To retrospectively analyzed the current application of warfarin in hospitalized patients with non-valvular atrial fibrillationand ( NVAF), explore the key role of clinical pharmacists in warfarin medication. Methods A retrospective survey of anticoagulant therapy for 179 hospitalized patients with non-valvular atrial fibrillation in Renming Hospotal of Wuhan University from January to December 2013 was retrived,including the usage of warfarin for NVAF and new-onset atrial fibrillation,dosage,international normalized ratio(INR),hemorrhage event and so on.The simple factor like the age,complicated chronic diseases and previous cerebrovascular events on the use of warfarin was explored. Results The total response rate to anticoagulants was 85.6% for patients with high risk of stroke(27.3% with warfarin and 58.3% with antiplatelet therapy),who are recommended to use warfarin,patient were treated with anti-thrombotic therapy.The total of 19.1% of the patients with new-onset atrial fibrillation used warfarin as therapy.The whole monitoring rate of INR was 89.8%,and the good control rate was 11.9%. Univariate analysis showed that some high risk factors such as age and high blood pressure affected the usage of warfarin. Conclusion The anti-thrombotic therapy for NVAF patients in the hospital is good,but usage of warfarin for those with new-onset atrial fibrillation is low,which couldn't reach the INR standard. More attention should be taken by the clinic pharmacists in effective managing the use of anticoagulant to build a safe,economic and effective medication system for warfarin application.

To ensure the safety of the commercially available chenpi, a convenient and fast analytical method was developed for the determination of 133 pesticide residues in chenpi using gas chromatography-tandem mass spectrometry (GC-MS/MS). In this study, different extraction solvents, redissolution solvents and adsorbents were tested according to the recovery and purification effect to obtain a modified QuEChERS method. The samples were extracted with acetonitrile. During the clean-up step, octadecyl-modified silica (C18) and graphitized carbon black (GCB) were selected, and aminopropyl (NH2) was used instead of primary secondary amine (PSA) because of its weaker ion exchange capacity which had little effect on the recovery of ditalimfos. Samples were quantified by matrix-matched calibration with internal stan-dards. All pesticides showed good linearity in the respective range, both with values of r2 >0.99. The average recoveries of the pesticides spiked samples ranged from 70.0% to 112.2% with the RSDs of 0.2%–14.4%. The modified QuEChERS method was validated and applied to twenty real samples. Five pesticides were found in eight batches, but no pesticide exceeded the maximum residue limits (MRL, MRL reference to European commission).

Aim To make a research of rats with focal cerebral ischemia/reperfusion injury on pathological changes in brain and the changes of AQP4 and related proteins, in order to explore the relationship between AQP4 and brain edema. Methods Adult male SD rats, weighting 250~300 g, were randomly divided in-to Sham group and cerebral ischemia/reperfusion ( I/R) injury model group. The I/R model group was di-vided into the I/R-6 h, 12 h, 24 h, 48 h-four time point groups. The animal model of the right MCA is-chemia/reperfusion was established by suture method in mature SD rats. The nerve symptom score was con-ducted in the corresponding time points. Then, the permeability of brain tissue was detected by EB stai-ning;TTC staining was conducted to observe the cere-bral infarction volume;the dry wet weight method was used to detect the changes of brain water content; im-munohistochemical( IHC) , WB and RT-PCR were ap-plied to detect the expression of AQP4 , and the related factors at different time points of the model rats after is-chemia-reperfusion around infarcts. Results Com-pared with the Sham group, then ever function score of the rats in I/R model groups were much higher. With the increase of the reperfusion time, the cerebral in-farction volume, brain tissue permeability and the brain water content were also increased. IHC results showed that AQP4 expression gradually rose with widen distribution. WB and RT-PCR results verified the in-creasing level of AQP4 expression. The detection of the related proteins expression showed apparent changes. The expression of MMP-9 was increased, while the Oc-cludin and JAM-1 expression showed a decreasing trend. The I/R-48 h model group showed the most ob-vious differences in the expression of the related pro-teins and mRNA ( P <0. 01 vs Sham, respectively ) . Conclusion Accompanied with the aggravating cere-bral injury after cerebral ischemia/reperfusion, the ex-pression of AQP4 and MMP-9 level were activated, while the degradation of TJPs, Occludin and JAM-1, was increased. These factors are combined to make the formation of brain edema. This study makes a further research on the formation mechanism of the early stage for cerebral edema on I/R model and offers a potential for intervention in the filed of looking for a reliable drug therapy on cerebral edema.
