Objective To investigate the effect of eosinophils(EOS)in asthmatic guinea pigs airway and explore the mechanism of antiasthma by inhaled arsenic trioxide. Methods The guinea pigs asthma models were established with ovalbumin(OVA)challenge method,2 groups received inhaled different doses of arsenic trioxide,and three control groups respectively received normal saline inhaled and high dose of arsenic trioxide by intraperitoneal injection and dexamethasone(DEX)intraperitoneally. EOS invaded and apoptosis with all of the groups were assessed after 7 days intraperitoneal injection or inhalation. Results Compared with group of inhaled normal saline, both EOS invaded and apoptosis in bronchus submuconsa were significantly different(P0.05)among groups of inhaled low dose arsenic trioxide [2.0 mg(kg?d)]and intraperitoneal injection with higher dose arsenic trioxide[5.0 kg/(kg?d)]and DEX[10 mg/(kg?d)]for these two parameters. Conclusions The mechanism of arsenic trioxide antiasthma with arsenic trioxide can decrease EOS amount in bronchial submucosa and accelerate EOS apoptosis, and relieve bronchial inflammation in asthma. For inhaled lower dose arsenic trioxide or intraperitoneal injection with high dose arsenic trioxide ,the effect of EOS is equivalent. The antiasthma effect of inhaled lower dose arsenic trioxide[2.0 mg/(kg?d)]is equivalent to intraperitoneal injection higher dose[5.0 mg/(kg?d)],and may be safe comparatively. The mechanism of antiasthma by inhaled arsenic trioxide is the same with DEX.

OBJECTIVE:To study the adhibition of misoprostol combined with palace cavity attraction tube in the treatment of painless abortion after cesarean section. METHODS:214 patients who received painless abortion after cesarean section were ran-domly divided into group A(71 case),group B(71 case)and group C(72 case). After all patients were given conventional intrave-nous anesthesia,Group A was given misoprostol 0.6 mg for oral administration in preoperative 2 h. Group B was given Misoprostol tablet 0.2 mg abrasive powder put in posterior fornix in preoperative 3 h. Group C did not give any drugs. All the groups used dis-posable suction curettage tube. The efficacies of sedation and cervical dilatation,operation time,intraoperative blood loss,recovery time,dosage of propofol and incidences of complications and adverse reactions in the 3 groups were observed. RESULTS:The op-eration time,intraoperative blood loss in group A were lower than group B and lower than group C,the differences were statistical-ly significant(P<0.05);recovery time and dosage of propofol in group A were lower than group B and C,the differences were sta-tistically significant(P<0.05),howerer,there was no significant difference between group B and C(P>0.05). The total effective rates of sedation and cervical dilatation in group A and B were significantly higher than group C,and the difference was statistical-ly significant(P<0.05),however,there was no significant difference between group A and B(P>0.05). The incidence of compli-cations in group A was lower than group B and lower than group C,and the difference was statistically significant (P<0.05). There was no significant difference in the incidence of adverse reactions among 3 groups(P>0.05). CONCLUSIONS:The efficien-cy and safety of misoprostol for oral administration or medicated vaginal suppository combined with palace cavity attraction tube in the treatment of painless abortion after cesarean section is similar,but oral administration can reduce the dosage of anesthetics,op-eration time and smaller intraoperative blood loss volume.

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 compare the dosimetric difference of volumetric modulated arc therapy (VMAT) plans for the loco-regionally advanced nasopharyngeal carcinoma (NPC) patients using 6 MV X-ray flattening filter-free (FFF) and flattening filter (FF) modes.Methods Ten previously treated patients with loco-regionally advanced nasopharyngeal carcinoma were retrospectively included and replanned using FFF and FF VMAT,respectively.Meeting all clinical criteria,the dose-volume histograms (DVH),dose distribution of target volume and organs at risk (OARs),target conformity index (CI),total monitor unites (MUs) and treatment time were compared across the plans.Results VMAT plans suing either FFF and FF modes can meet the clinical objectives.The maximum and mean target dose of FFF VMAT plans were significantly higher than that of FF VMAT plans (t =-0.31,-O.35,P ＜ O.05).Yet the planning target volume (PTV) CI of FF mode was slightly better than of FFF mode (t =5.42,P ＜0.05).The maximum doses of lenses in FFF VMAT plans were lower than that of FF VMAT plans (t =25.87,17.45,P ＜ 0.05),and other OARs displayed no significant difference.The mean total MUs of FFF and FF VMAT plans were (699 ± 16) and (628 ± 12) MUs respectively.The mean treatment time of two modes were consistent (about 2 min).Conclusions The plan qualities of FFF and FF VMAT plans were comparable and both clinically acceptable.The OARs at the edge of radiation field,such as lens,could be spared better using FFF VMAT mode.The total MUs of FFF VMAT plans were higher than FF VMAT plans,yet were delivered within the same time.

Objective To evaluate the image deformation and measurement error of rotational DSA by model experiment. Methods Five steel balls (diameter: 20 mm) were placed in a horizontal space of 30 mm, the middle of which was as the isocenter for rotational DSA acquisition. Another 5 steel balls (diameter: 10 mm) were placed in a vertical space of 30 mm with the same alignment for rotational DSA acquisition. The screen was divided into five regions and the morphological changes of the ball image were observed at each rotation angle. The experimental images of the left anterior oblique ball images at 20°, 40°and 60° among each two groups were selected and measured by automatic isocenter calibration and sphere calibration respectively, and compared with the actual diameters of balls to calculate the image magnification. Results Except the center one, other balls were of deformation at different rotation angles due to the distance to the detector leading to enlargement and reduction. With automatic isocenter calibration, only the diameter of the center ball corresponded with the actual one, the distance away from the center or the rotation angle was inversely proportional to measurement error (maximum magnification 12.42%).With sphere calibration, the measurement results in various regions at different rotation angle were basically the same, with smaller measurement error (maximum magnification 3.41%). Conclusion Placing the organ of interest in the center area can reduce image distortion in rotational DSA imaging. Selecting reasonable measuring technology according to the lesion location is helpful to control measurement errors.
