Objective To explore the effect of labels management on high-risk drugs. Methods Labels management group was established, to be responsible for use and storage of high-risk drugs. The management methods included taking analysis on adverse nursing events, designing and making labels in drug storage and use, and making a field survey on adverse nursing events before and after the management. Result After manipulation of the labels management, the number of adverse nursing events of drug use fell from 35 to 0. Conclusion Drug storage and use with special, standard labels is effective in preventing nursing adverse events in high risk drugs.

OBJECTIVE:To prepare psoralen liposome gel and to conduct a quan titative investigation about its drug re?lease model in vitro.METHODS:Taken psoralen liposome gel that of the same concentration as the control group,the model of drug release in vitro of the testing group was evaluated by dialyzing method and the stability of its drug release after storage for3weeks at4℃was studied as well.RESULTS:Compared with the control group,the testing group showed significant slow-releasing and long-acting effects and the drug release followed the Higuchi(k=4.67%h -1/2 )diffusion model in the first3hours and a zero order drug release model(k=0.74%h -1 )3hours later;The drug release of the control group followed the Higuchi(k=7.18%h -1/2 )diffusion model of within24hours;The drug release model and the envelop rates of the testing group remained stable within the storage date.CONCLUSION:This preparation is characterized by slow drug releasing in vitro and good stability.

Objective To establish a hydrogen peroxide-impaired model of rat cerebral microvascular endothelial cells in vitro, and observe the protective effect of serum containing Naoyian. Method Rat cerebral microvascular endothelial cells were treated with six concentrations of hydrogen peroxide at four time points. The optimum injury condition of hydrogen peroxide was determined by MTT chromatometry. Then the cultured cells pretreated with serum containing Naoyian and pyrrolidine dithiocarbamate(PDTC) were interfered with hydrogen peroxide in suitable concentration and time, and OD of the treated cells was measured by MTT chromatometry. Results The cultured cells were injured obviously by hydrogen peroxide in 0 125mmol/L for 30min. The OD of the cells pretreated with 5% serum containing Naoyian and 50?mol/L PDTC were significantly higher than that of the cells without pretreatment (P

Objective To investigate the possible roles of serum bilirubin and uric acid in the course of carotid artery intima thicken/plaque formation. Methods Patients with ischemic cerebral vascular disease were divided into the control group, intima thicken group and plaque formation group according to the carotid artery intimamedia thickness (IMT) examination by B-mode ultrasound. The serum bilirubin and uric acid were detected by Automatic Chemistry Analyzer. Results The serum level of uric acid of (391.22 ± 27.52) μmol/L in intima thicken group was significantly higher than that in the control group and plaque formation group((307.32 ± 13.68)μmol/L and (327.84 ± 17.96)μmol/L, P ＜ 0.05). The serum level of indirect bilirubin and total bilirubin in plaque formation group was (10.96 ± 0.58) μmol/L and (15.91 ± 0.71) μmol/L respecitively, which were significantly lower than those in the control group ((15.09 ± 2.21) μmol/L and (20.59 ± 2.43) μmol/L,respectively) and the intima thicken group((15.09 ± 2.21) μmol/L and (20.59 ± 2.43) μmol/L, respectively) (Psignificantly lower than that of (5.70 ± 0.28) μmol/L in the control group(P ＜ 0.05). Conclusions Bilirubin and uric acid play different roles in carotid artery plaque formation during different stage.

To compare the clinical effect of phacoemulsification and middle incision extracapsular cataract extraction ( Ml-ECCE) . METHODS: One hundred and eighty - five eyes of phacoemulsification (137 cases) and 185 eyes of 139 cases for Ml-ECCE from January 2011 to May 2013 were involved in this study. And the ratio posterior capsular rupture during surgery, visual acuity, corneal edema, corneal astigmatism and intraocular pressure post operation were followed up.RESULTS: On 1d after surgery, uncorrected visual acuity in the group of Ml-ECCE was better than that of phacoemulsification group, while from 3d; 1 and 3mo after surgery, no significant difference was found from the above two groups. On 1d postoperation, corneal edema ratio in phacoemulsification group ( 45 eyes ) was higher than that in Ml-ECCE group(20 eyes) ( X2=11. 665, P=0. 0006 ) . No significant difference was found for the ratio of posterior capsule rupture during surgery in these two surgical technique groups(X2=0. 094,P=0. 759). On 1wk;1 and 3mo after surgery, significant difference was found for the average of surgical induced corneal astigmatism between two groups (u=6. 661, 6. 880, 4. 187, P = 0. 00, respectively ). During following up, no significant difference was found for the intraocular pressure between two groups ( u=1. 858, 0. 963, 0. 471, 1. 349, 1. 388; P= 0. 063, 0. 335, 0. 638, 0. 177, 0. 165). lntraocular pressure on 1d postoperation in phacoemulsification and Ml-ECCE groups was higher than before operation ( u = 19. 86, 19. 39, P = 0. 00, respectively). And on 1wk; 1 and 3mo postoperation, intraocular pressure in the operated eyes in both groups was lower than before operation for 2~3mmHg.CONCLUSlON: Although phacoemulsification and Ml-ECCE could both get good visual rehabilitation, with similar visual outcome, no significant effect for intraocular pressure, and no severe complications, the latter one owns the advantage that easier maneuver, quicker recovery, and cheaper instruments needed, which is suitable for the hard nuclei cataract in local hospitals. Ml-ECCE is a safe, effective and easy manipulation for local hospital for large batch of cataract surgeries.

OBJECTIVEThe device of a bone age film of analysis and process was designed, can calculate the expected patient's height and identify growth level and development.

METHODSSelect the DR bone age of 100 children of 6-13 years old, used semi Lagrange algorithm of target region of interest on bone age piece (ROI) for image analysis, compared with 2 pediatric endocrinologists (A, B) who used TW3 artificial to judge bone age (two methods were detected 2 times), and report the results.

RESULTSBone age assessment process, forecast error of bone age reduced to 0.12 years.

CONCLUSIONSThis device can quickly calculate the expected patient's height and identify his growth level, improve the speed and accuracy of bone age assessment, especially in the poor medical conditions in rural and remote areas.

Objectives To study the efficacy of the two-compartment peritoneal dialysis fluid with low glucose degradation products in peritoneal dialysis (PD) patients.Methods Pubmed,EBMASE,Cochrane Library,Wanfang,VIP,CNKI,CBM and other databases were searched,at the same time the information form relevant literatures until December 2013 were searched by hand.To be eligible,studies had to be randomized controlled trials that allocated PD patients to two-compartment peritoneal dialysis fluid with low glucose degradation products (low-GPDs group) or to traditional dialysis fluid (control group).The qualities of included articles were assessed and then a meta-analysis was conducted by using RevMan 5.2 software.Results A total of 12 documents,11 studies met the inclusion criteria,and 1 059 cases were included.Meta-analysis results were as follows:(1)the low-GPDs group had higher level of CA125 in peritoneal dialysis effluent,higher residual renal function compared with that in the control group and the weighted mean difference were 19.61 (95％CI 12.04-27.18,P ＜ 0.01) and 0.78 (0.14-1.43,P=0.02),respectively; (2)There was no statistically significant difference between control and low-GPDs group in the ultrafiltration,peritonitis and plasma bicarbonate (all P ＞ 0.05); (3)Four studies showed no difference in peritoneal dialysis technique survival between the two group (P ＞ 0.05).Conclusions The two-compartment peritoneal dialysis fluid with low glucose degradation products is effective and safe,has no negative effects on the frequency of peritonitis,patient' s peritoneal member transport function and plasma bicarbonate,but it causes less mesothelial damage and has higher residual renal function in patients than conventional ones,and does not affect the technique survival time.
