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.

Objective To evaluate the effects of anisodamine on apoptosis in cardiomyocytes and inflammatory response in overtrained rats. Methods Twenty-four male Wistar rats, weighing 200-220 g, were randomly divided into 3 groups ( n = 8 each) : control group (group C) , overtraining group (group O) , anisodamine group (group A) . The model of overtraining-induced acute heart injury was established by exhausting swimming. Anisodamine 10 mg/kg was given intraperitoneally 20 min before overtraining in group A. Blood samples were taken at 6 h after overtraining for measurement of serum CK-MB activity. The rats were then sacrificed and myocardial tissues taken for determination of TNF-α content and NF-κB activity (by immunohistochemistry) . The apoptosis rate was detected by flow cytometry. Results The CK-MB activity, apoptosis rate, TNF-α content and NF-κB activity were significantly higher at 6 h after overtraining in groups O and A than in group C, while lower at 6 h after overtraining in group A than in group O ( P < 0.05) . Conclusion Anisodamine can inhibit apoptosis in cardiomyocytes by reducing inflammatory response in overtrained rats.

Objective To investigate the infection prevention effect of prophylactic use of antibiotics for cancer inpatients with leukocyte count ≤ 1 × 109/L.Then to provide the basis for rational use of antibiotics.Methods It was retrospectively surveyed that the infection situation and prophylactic usage of antibiotics in the 426 cancer inpatients with leukocyte count ≤ 1 × 109/L caused by radiotherapy and chemotherapy.Results In the 426 inpatients,the infection rates of patients with and without prophylactic use of antibiotics were 11.0％ and 20.9％ respectively.The difference was statistically significant (x2 =6.815,P =0.009).The leukocyte count median values of patients with and without infection were 0.73 × 109/L and 0.77 × 109/L respectively.The difference had no statistical significance(Z =-1.257,P =0.209).The main infection sites were lower respiratory tract,upper respiratory tract and gastrointestinal tract with infection rates of 48％,12％ and 11％,respectively.The top five pathogens were Klebsiella pneumonia,Enterobacter cloacae,Escherichia coli,Enterobacter aerogenes and Staphylococcus aureus.The most use of antibiotics were cephalosporin.Conclusion When the leukocyte counts of cancer inpatients are less than or equal to 1 × 109/L induced by chemotherapy and radiotherapy,reasonable prophylactic use of antibiotics can reduce hospital infection rates.

Objective To investigate the changes in trafficking of GluRl-containing AMPA (GluR1-AMPA) receptor and GluR2-AMPA receptor from cytoplasm to cell membrane in the spinal cord dorsal horn in a rat model of incisional pain.Methods Thirty-two adult male SD rats aged 6-8 weeks weighing 280-300 g were randomly divided into 2 groups:control group (group C,n =8) and incisional pain group (group Ⅰ,n =24).An 1 cm long incision was made in the plautar surface of right hindpaw according to Brennan et al.in group Ⅰ.Cumulative pain score (CPS) and paw-withdrawal threshold to yon Frey stimuli (PWT) were measured at 3 h and day 1 and 3 afar incision ( T1,2,3 ).The animals were sacrificed after pain behavior assessment.Their lumbar segments of the spinal cord (L3-6) were removed.The expression of GluR1 and GluR2 in cell membrane and cytoplasm in spinal cord dorsal horn was determined by Western blot analysis.The co-expression of Stargazing with GluR1 and GluR2 in the spinal cord dorsal horn was examined by co-immuno-precipitation.Results The CPS was increased and PWT decreased; the GluR1 expression in cytoplasm was decreased while the expression of GluR1 in cell membrane and the co-expression of Stargazing with GluR1 were up-regulated in group Ⅰ as compared with group C.There was no significant change in the expression of GluR2 in cytoplasm and cell membrane and the co-expression of Stargazing with GluR2 in group Ⅰ as compared with group C.Conclusion GluR1-AMPA receptor transfers from cytoplasm to cell membrane but GluR2-AMPA receptor does not in rats with incisional pain.

OBJECTIVETo explore the possible target and molecular mechanism of Radix Paeoniae 801 (RP801), an effective ingredient extracted from Radix Paeoniae, the Chinese herbal medicine for activating blood circulation to remove blood stasis, using experimental in vitro method by directly detecting the interaction between RP801 and endothelin-1 (ET-1).

METHODSPiezoelectric quartz crystal biosensor, namely, the quartz crystal microbalance (QCM) was used to detect the specific combining between RP801 and ET-1 by binding avidin to the pre-activated Au surface of electrode of QCM, followed by immobilizing biotinylated ET-1 to it, and adding RP801, then the binding curve was recorded. PBS washing was applied at the end of every steps of combining reaction for dissociate the non-specific absorption.

RESULTSSpecific combining of RP801 and ET-1 was found.

CONCLUSIONET-1 could possibly be one of the acting targets of RP801 in the body, that is, RP801 could combine with ET-1 to impede the binding of ET-1 with its receptor, so as to counteract the action of ET-1, dilate blood vessels and inhibit platelet aggregation.

Leukemia inhibitory factor (LIF) plays important roles in varieties of biological processes. This factor is highly conserved in mammalian animals and only one heterozygous LIF mutation was reported to cause the infertility of women. A LIF mutation was generated and the evidences were provided that the mutation of mature LIF at the 29th amino acid totally abolished its functions, including stimulation of STAT activation assayed by Luciferase reporter gene expression and EMSA experiments. In addition, the mutated LIF failed to inhibit the proliferation of M1 cells. The data indicated that the mutation of LIF did not have a dominant negative effect but lost the biological functions, suggesting that the 29th amino acid is critical for maintaining the activities of LIF.

Objective To describe a novel surgical technique for male long-segment urethral stric- ture after pelvic trauma using the intact and pedieled pendulous urethra to replace the bulbar and membra- nous urethra,and then reconstructing anterior urethra.Methods Three patients with long-segment post- traumatic bulbar and membranous urethral strictures with short left pendulous urethras who had undergone several failed previous surgeries were treated with staged pendulous-prostatic anastomotic urethroplasty fol- lowed by reconstruction of the anterior urethra.This procedure was divided into 3 stages.The first-stage sur- gery was mobilization of anterior urethra down to the coronary sulcus and then re-routing the prostatic urethra followed by pendulous-prostatic anastomotic urethroplasty with transposition of penis to perineum.The sec- ond-stage surgery was transecting the anterior urethra at the site of coronary sulcus 6 months later when it was re-vaseularized,then straightening the penis and performing urethroperineostomy.The third-stage surgery was reconstruction of anterior urethra 6 months later.Results Case 1 reported satisfactory voiding postopera- tively.Retrograde urethrography showed that the urethra was patent with no post-voiding residual urine (PVR),and bilateral vesicoureteral reflux almost disappeared.The Qmax was 18.8ml/s,and 18ml/s after the third stage surgery and at 2-year follow-up.Case 2 also had satisfactory voiding.A 22F urethral catheter could smoothly pass through the urethra,and Qmax was 19.5 ml/s with no PVR at 2-year follow-up.Case 3 underwent the first stage surgery through perineal and pubic routes.The urethrorectal and urethroperineal fis- tulas were excised and repaired simultaneously.After operation the fistulas healed,but the stenostomia resul- ting from wound infection needed further treatment.Conclusions This procedure is effective for men with complex long-segment post-traumatic bulbar and membranous urethral strictures,especially for those undergo- ing failed previous surgical treatment.
