Opioids were widely applied to analgesia and treatment of coughing, diarrhea, anxiety and sleepless. Opioids had toxic effects while playing pharmaceutical roles with oxidative injury as one of the most important toxic effects. Multi-organ or systems in our body were more liable to be damaged either by opioids reduced concentration of glutathione, the reductant or antioxidant, or by increased concentration of reactive oxidative species. To further clarify the research progress in opioids induced oxidative injury is very important towards opioids applications as well as prevention and cure of drug abuse.

OBJECTIVE:To evaluate the safety of acyclovir in the treatment of liver-transplanted children with EB-viremia. METHODS:Retrospectively analysis was conducted for the general information of 10 liver-transplanted children with EB-viremia, preoperative donor and recipient EBV infection and treatment,tacrolimus dose and plasma concentration before and after interven-tion,platelets,serum creatinine and white blood cell levels before and after treatment,and the recurrence were followed-up. RE-SULTS:Biliary atresia was the primary disease for all the children,EB virus polymerase chain reaction(EBV-PCR)was positive, and there was no routine testing for donor HBV infection;6 cases reduced the tacrolimus dose,4 remained unchanged,and 9 cas-es of plasma concentrations reduced after intervention,9 were negative and 2 recoveried. There were no significant differences in the platelets,serum creatinine and white blood cells before and after treatment(P>0.05). CONCLUSIONS:Acyclovir can be used in the treatment of liver-transplanted children with EB-viremia,with good safety.

In present study, standard method and standard operation practice for measuring the activities of influenza neuraminidase and its inhibitors have been established. The accuracy and stability of the method has been evaluated. Standard operation is as following: 10 microL sample, 30 microL neuraminidase and 60 microL substrate are added to one well of a 96-well plate, and then incubated at 37 degrees C for 1 h. The reaction was stopped with NaOH before fluorescence intensity determination. One unit of neuraminidase is defined as the amount of enzyme that produces 1 nmol 4-MU in 1 h under above conditions. The inhibition accuracy is indicated by an uncertainty measurement of 6.51 x 10(-12), and its stability was reaffirmed by determination of oseltamivir acid. In this study, systematic assessment of neuraminidase inhibitory assay not only provided theoretical basis of its application in drug discovery, but also made preliminary attempt to use uncertainty measurement as a parameter in biological measurement.

ObjectiveTo observe the curative effect of alprostadil combined with cilostazol in treatment of patients with lower limb atherosclerosis.MethodsSixty-two patients with lower limb atherosclerosis were divided into cilostazol group (cilostazol 100 mg,2 times a day,oral) and therapeutic alliance group (cilostazol 100 mg,2 times a day,oral; alprostadil 10 μ g dissolved in 100 ml intravenous infusion of 0.9％ sodium chloride,once a day) by random number table with 31 cases each.The changes of ankle-brachial index (ABI),distance of 6-minute walk test(6-MWT) and the dorsal blood flow were compared before and after treatment.Results | After treatment,the distance of 6-MWT,ABI and the level of dorsal blood flow were significantly improved in two groups (P ＜ 0.05 or ＜ 0.01 ).Distance of 6-MWT and the level of dorsal blood flow in therapeutic alliance group was significantly higher than that in cilostazol group after treatment [(425.4±138.5) m vs.(379.5±124.6) m,(0.77±0.18) ml/ (s·cm2) vs.(0.66±0.14) ml/( s· cm2)] ( P＜0.05 ).The total effective rate in the treatment of cold feel in therapeutic alliance group was significantly higher than that in cilostazol group [ 87.5％(21/24) vs.61.9％( 13/21 ) ](P＜ 0.05).Conclusion Alprostadil combined with cilostazol is safe and effective in treating lower limb atherosclerosis.

Objective To investigate the inhibition effect of silencing Ku80 gene combined with irradiation on growth of esophageal cancer xenografs. Methods shRNA-Ku80 vector was constructed.The expression of Ku80 protein was inhibited by shRNA-Ku80 vector by using Western blotting. 20 BALB/c nude mice were randomly divided into 4 groups, including control group, radiation group, shRNA-Ku80 group and combined group. The growth of esophageal cancer xenografs was observed. The expression of Ku80 was examined in esophageal cancer xenografs by IHC. Results Effective target sequence was selected. The growth of esophageal cancer xenografs was inhibited by shRNA-H2 and radiation, especially in combined group. The inhibition rate of growth in three groups above was 32.0% , 39. 9% and 68. 9% ,respectively. The expression of Ku80 was reduced to 58% by shRNA-H2 in esophageal cancer xenografs ( t = 3.77, P ＜ 0. 05 ). Conclusions Combination of silencing Ku80 and radiation could enhance radiotherapeut effect of esophageal cancer xenografs.

Chop and Grp78 genes are key genes in endoplasmic reticulum stress(ERS).To explore the gene alteration of Chop and Grp78 in embryo with spina bifida,we studied Chop and Grp78 gene expression by qRT-PCR in neural tube of rat with spina bifida in E12 and primary cultured neuroepithelial stem cells(NEP).We found higher expression of both Chop and Grp78 in neural tube of rat with spina bifida than normal rats.While Chop and Grp78 genes were up-regulated after NEP differentiated into neuron.The up-regulation of Chop and Grp78 genes in neural rube of rat and NEP might be involved in the abnormal apoptosis in spina bifida related with ERS.And we found the primary culture of NEP provided a good model for embryo early development research.

Objective To probe into the burden of caregivers of patients with Alzheimer' s disease (AD) ,coping styles and the correlation. Methods A survey involving 143 caregivers of patients with AD was conducted with Caregivers' Burden Scale and a simple Coping Style Questionnaire to analyze the burden of caregivers of AD and the characteristics of their coping styles and discuss the correlation. Results The burden of the caregivers of patients with AD was at intermediate level the score was 46. 96 ±7. 28. 78. 32% of the caregivers had intermediate burden. Both the grade of the positive coping and that of the negative coping of the caregivers of patients with AD were higher than the domestic norm (P < 0.01); the positive coping styles of the caregivers of patients with AD were negatively related with their burden while nursing; their negative coping styles were positively related with their burden while nursing (P < 0.01). Conclusion The burdens while nursing are related with their coping styles. In the aspect of nursing activity, caregivers should be encouraged to adopt positive coping styles.

Objective of the study is to explore how to apply ARIMA model in prediction of outpatients headcount,describe the modeling process,build the prediction model,and verify its applicability to serve decision making for hospital management.Methods Data originates from the outpatient statements of the HIS integrated statistics and management decision making support system.The data collection ranges from the monthly outpatients headcount from 1999 to 2005,in which the monthly data from 1999 to 2004 were used to build the time sequence model,and those of 2005 to verify the model so built.The statistic software was programmed with SPSS13.0.Results The ARIMA(1,0.1)(0,1,1)12 model was built by megns of model identification,parameter estimate.inspection/diagnosis,and model appraisal.This model features high fitting precision,as the relative error or outpatients headcount for the year is 6.85%,and that for the months ranges from-3.15%to-9.80%,with the actual values falling within the 95%upper and lower thresholds of the prediction results.Conclusion This study proves that ARIMA model fits the purpose of outpatients headcount prediction.In the meantime,prediction of such headcount should also take into account such factors as the data volume,hospital environment and patient satisfaction.

Objective To analyze factors influencing the incidence of deep venous thrombosis (DVT) and discuss the prevention and treatment of DVT in hip fracture patients. Methods The present study enrolled 531 patients who received surgery between June, 2008 to June, 2010 for hip fractures. They were 242 men with a mean age of 56. 2 years and 289 women with a mean age of 65.2 years. There were 336 femoral neck fractures, 183 femoral intertrochanteric fractures, and 12 femoral subtrochanteric fractures. The associations between DVT incidence and fracture type, plasma D-Dimer, sex, age and preoperative duration of immobilization were statistically analyzed. Inferior yens cava filters were used for patients who suffered DVT while surgery was performed. Results The total incidence of DVT was 10. 4% in this series. DVT occurred in 21 cases of femoral neck fracture, 34 cases of femoral intertrochanteric fracture and 0 case of femoral subtrochanteric fracture. All DVT events happened before surgery. DVT incidence had no significant associations with age or sex (P =0. 347 and 0. 376, respectively), but did with plasma D-Dimer, fracture type and preoperative duration of immobilization (P = 0. 002, 0. 017 and 0. 037, respectively). All the 55 DVT patients underwent a successful surgery. Conclusions The DVT incidence in hip fracture patients may have no significant associations with age or sex, but may do with plasma D-Dimer, fracture type and preoperative duration of immobilization. Inferior vena cava filters can ensure a successful internal fixation of the fracture and an uneventful postoperative rehabilitation.

Objective To investigate the diagnostic value of low field MRI for adenomyosis. Methods MRI features of adenomyosis pathologically proved in 18 cases were retrospectively analysed.Results 15 cases were diffusive adenomyosis,the junctional zones of uterus were exteusive thickened to 12.0～32.6 mm,mean 16.2 mm,diffusive high signal intensity distributed over in myometrium which was low signal intensity in 11 cases,it was typical “snowing sign”,lower signal intensity in the myometrium in another 4 cases on T 2WI and fat-suppression imaging. A little high signal intensity was found in 6 cases on T 1WI. 3 cases were focal adenomyosis(adenomyoma), 4 lesions totally. The adenomyoma’s boundaries were not distinct and their shapes were roundish or irregular. The lesions were low signal intensity or diffusive high signal intensity distributed in the low signal intensity fields on T 2WI and fat-suppression imaging. A little high signal intensity was found in 2 lesions on T 1WI. Conclusion T 2WI and fat-suppression imaging of low field MRI are very useful techniques of the diagnosis of adenomyosis.
