OBJECTIVE:To investigate the application effect of PDCA circulation method in clinical pharmaceutical care. METHODS:According to the method of PDCA cycle,clinical pharmaceutical care quality and satisfaction degree of physicians, nurses and patients in 2013 were investigated to find out the problems;the reasons were analyzed and countermeasures were made out,checked and implemented. Finally,the quality of clinical pharmaceutical care,the medical staff and patient's satisfaction with clinical pharmaceutical care were compared before and after the implementation of PDCA circulation. RESULTS:Due to the poor quality of clinical pharmaceutical care and low satisfactory degree of our hospital,we formulated related countermeasures,such as enhancing the medication service skill of clinical pharmacists in obstetrics and gynecology department,extending the coverage of pharmaceutical ward round,developing the pharmaceutical care for patients with high risk pregnancy or underwent assisted repro-duction,strengthening communication and propaganda of medical staff and patients. After the implementation of countermeasures, the quality indicators of clinical pharmaceutical care were improved in 2014,compared to 2013,such as the number of patients in-cluded in pharmaceutical ward round increased from 445 to 1 780;total number of reasonable medication intervention suggestion in-creased from 14 to 29;that of pharmaceutical consultation increased from 8 to 23;the satisfaction degree of medical staff and pa-tients improved from 55.93% and 45.95% to 100% and 92.10%,respectively. CONCLUSIONS:PDCA circulation can significant-ly improve the quality of clinical pharmaceutical care and satisfactory degree of our hospital,and promote pharmaceutical care of our hospital.

Objective AMI is a prevalent global health condition.This study assessed the effects of PLGF and VEGF in a rat model of post-AMI.Methods Wistar rats underwent LAD ligation and injection of VEGF,PLGF,VEGF + PLGF,antiVEGFR1,anti-VEGFR2,anti-VEGFR1 + anti-VEGFR2,IgG2α,or saline,into the infarct border zone.We also set up a pseudo-operation group.Two weeks later,heart function was detected by hemodynamic and geometry,then the hearts were dis sected and HE stained.We assessed vW factor and α-SMA by immunohistochemistry and cardiomyocyte apoptosis rate by TUNEL.Results Rats in the VEGF + PLGF group performed significantly well in cardiac function,had weaker LV remodeling and less cardiomyocyte apoptosis.There were no obvious changes in VEGF group.The use of VEGFR1/VEGFR2 antibody didnt deteriorate the rat's cardiac function.More new-born arteries were seen in PLGF and VEGF + PLGF rats,and change wasnt found in other groups.Lastly,the most angiogenesis,the least left ventricular remodeling and the best heart function were observed in VEGF + PLGF group.Conclusion Earlier intervention with PLGF or VEGF + PLGF can improve heart function in rats with AMI; VEGF alone didnt improve heart function.VEGFR1/VEGFR2 antibody didnt aggravate the rat's heart function.This indicates that left ventricular and coronary remodeling may involve other factors.

Purpose To analyze the gait of patients following reconstruction of posterior cruciate ligament(PCL) and posterolateral corner(PLC).Methods Between March 2007 and April 2008,16 patients with combined PCL and PLC injuries-deficient knee underwent the reconstruction with allograft.Dial test were performed before surgery,and gait analysis and dial test were assessed 1 year after reconstruction.Sixteen healthy volunteers were used as controls.Results There are no differences in the time-distance factors and kinematics between patients and controls(P>0.05).The torque of knee extension revealed significant difference between patients and controls(P<0.01).Mean abtorsion angle of the patients increased 16.5°±6.2° before surgery;whereas the angle increased-4.4°±7.8° 1 year after surgery(P<0.01).The maximal mean abtorsion angnlation from gait analysis was 14.1°±15.7° and from dial test was 29.7°±1 5.2°,respectively.There was a strong linear correlation(r=0.9671,P<0.05)between the outcomes from dial test and gait analysis.Conclusion After reconstruction of the PCL and PLC,the gait of patients became almost normal 1 year after operation,except the torque of knee extension.

ObjectiveTo examine the relationship between HIF-1αt and VEGF expression and the clinicopathological characteristics in hypopharyngeal squamous cell carcinoma. Methods The expression status of HIF-1α and VEGF were examined by immunohistochemistric method (IHC) in 62 tumor tissue and 19 paracancerous normal tissue.The relationships between the expression of HIF-1α and VEGF and clinicopathological characteristic were analyzed. Results HIF-1αt and VEGF expression were higher in hypopharyngeal carcinoma tissues than those in paracancerous normal tissues (66. 1％:26. 3％ ;x2 =18. 02,P ＜0. 05 ;67. 7％ : 31.6％ ; x2 =19.22, P ＜ 0. 05 ). The expression intensity of HIF-1 α was related to T stage, N stage and TNM stage ( x2 =4. 23,5.83,9.94,all P ＜0. 05). The expression intensity of VEGF was related to metastasis, T stage, N stage and TNM stage (x2 =5.62,7. 38,15.75,4. 29 ,all P ＜0. 05 ). There was minus relationship between overall survival and expression level of HIF-1 α and/or VEGF (x2 =29. 25, P＜0.01; x2 =24.88, P＜ 0.01 ).On multivariate analysis,HIF-1α expression and T stage were independent prognostic factors for overall survival (x2 =4.80,5.74, all P＜0. 05).ConclusionsHIF-1α and VEGF may be considered as a parameter in evaluation of progression, metastasis and prognosis of hypopharyngeal carcinoma and also may be a direction of molecular target therapy.

Background Retinopathy of prematurity is mainly due to retinal neovascularization.Objective This laboratory work was to evaluate the efficacy of different dosage of avastin for inhibiting retinal neovascularization.Methods Ninety 7-day-old clean C57BL/J6 mice were randomized into six groups as follows:air control group,hyperxia control group,hyperxia BSS group and avastin groups.C57BL/J6 mice in air control group were raised in regular air environments.The fifty mice were fed under the environment with 75％ ±2％ oxygen for 5 days to establish the retinal neovascularization models.The 1.25,2.50 and 5.00 g/L avastin (0.5 μl) were injected inteavtreally in forty-five mice models as low,moderate and high dosage avastin groups respectively,and 0.5 μl BSS was used at the same way in fifteen models as hyperxia BSS group.The mice were sacrificed in the 17-day-old age using excessive anesthesia method and the retina sections were prepared for the calculation of the numbers of vascular endothelial cell nuclei broken retinal inner membrane after hemotoxylin and eosin staining.The expression of CD34 in the retina was detected by immunochemistry.The morphology and distribution of retinal neovascular vessel in various groups were observed using retinal flat.The use of the animals followed the Regulations for the Administration of Affairs Concerning Experimental Animals by State Science and Technology Commission.Results The numbers of cell nuclei broken the inner limiting membrane was significant increased in the hyperxia group compared with the air control group( P＜0.01 ),and those in difference doses of avastin were considerably reduced in comparison with hyperxia BSS group (P＜0.01) and hyperxia group (P＜0.01 ).The decrease of numbers of cell nuclei broken the inner limiting membrane was obvious in low dose of high dose of avastin compared with low dose of avastin (P＜0.05 ).CD34 was positively expressed in retina internal membrane of hyperxia group.Retinal flat revealed the regular distribution and normal structure of retinal vessels in air control group and avastin groups.However,retinal and vitreous cavity neovascularization,leakage and enlarged non-perfusion regions in the perimeter of the retina were seen in hyperxia group and hyperxia BSS group. Conclusions Intravitreal injection of avastin can arrest retinal angiogenesis in oxygen-induced retinal neovascularization models in a dose-dependent manner.
