Objective To investigate the therapeutic effect of distal radius fractures operation.Methods Eighty distal radius fractures patients who were treated from January 2010 to January 2011 were divided into observation group and control group by random digits table method,each group had 40 cases.The observation group was treated with plate internal fixation,the control group took closed reduction and splint external fixation.The palmar tilt,radial ulnar deviation,axial shortening before treatment and after treatment for 3 months were compared between two groups.The clinical curative effect after treatment for 1 year was compared.Results The palmar tilt,radial ulnar deviation,axial shortening before treatment between two groups had no significant difference (P ＞ 0.05).After treatment for 3 months,the palmar tilt,radial ulnar deviation,axial shortening in observation group were (17.0 ± 1.6)°,(23.0 ± 2.1)°,(1.0 ± 0.2) mm,in control group were (4.0 ± 0.8)°,(10.0 ± 1.1)°,(4.0 ± 1.1) mm,there was significant difference(P＜ 0.05).After treatment for 1 year,the excellent and good rate in observation group was 90.0％(36/40),significantly higher than that in control group [50.0％ (20/40)] (P ＜ 0.05).Conclusion Plate internal fixation in the treatment of distal radius fractures is more conductive to the wrist recovery of joint structure and function,reduce the occurrence of wrist joint dysfunction,improve the quality of life,and is worth to be applied in clinic.

Objective To explore the prognostic factors of osteosarcoma.Methods Clinical data of 32 cases with osteosarcoma were retrospectively reviewed.Sex,age,course of disease,serum level of alkaline phosphatase (AKP),tumor size,tumor site,Enneking surgical stage,surgical method and distant metastasis were statistically analyzed.Results All the patients were followed up,and 12 patients died with a median survival of 6-52 (40.28 ± 5.58) months.Overall survival rate of 3 years was 62.5％ (20/32).Univariate analysis revealed that the prognosts of osteosarcoma was significantly related to tumor site,Enneking surgical stage,surgical method and distant metastasis.Multivariate analysis suggested that Enneking surgical stage,surgical method and distant metastasis were independent prognostic factors.Conclusions Enneking surgical stage,surgical method and distant metastasis are independent prognostic factors.Early diagnosis and the radical resection of tumor can improve the prognosis.

ObjectiveTo explore salivary concentration of carcinoembryonic antigen (CEA),interleukin (IL)-6,IL-8 in oral squamous cell carcinoma and its' clinical significance.MethodsForty-two cases with oral squamous cell carcinoma were selected as experience group and 50 healthy persons as control group.ELISA method was performed to detect CEA,IL-6,IL-8 level of salivary and serum in two groups.ResultsThe salivary concentration of CEA,IL-6 and IL-8 was (62.37 ± 20.80)μ g/L,(79.12 ± 30.26)ng/L,( 834.61 ± 231.85 ) ng/L respectively in experience group,(25.72 ± 12.65 ) μ g/L,(0.58 ± 0.25 ) ng/L,(209.71 ± 67.92) ng/L in control group.There was significant difference between two groups(P＜ 0.01 ).The serum concentration of CEA,IL-6 and IL-8 was(61.15 ± 23.69)μ g/L,(58.17 ± 12.83) ng/L,(852.31 ±172.97) ng/L respectively in experience group,and IL-6 level of serum were much lower than that of salivary (P ＜ 0.05).ConclusionsCEA,IL-6 and IL-8 can be biomarkers of oral squamous cell carcinoma.Salivary detection is an ideal auxiliary diagnosis method for its simplicity and sensitivity.

The organic cation transport systems were initially recognized in studies of renal elimination.A variety of endogenous and exogenous compounds that are harmful to the body are eliminated from the kidney via glomerular filtration and/or active tubular secretion.Among those compounds are polar organic cations that require a transporter-mediated process to cross cellular membrane and be eventually excreted into the urine.The organic cation transport systems in the kidney have been recognized for several decades.Following the insight gained from the kidney,organic cation transporters (OCTs) have also been characterized in other tissues.In particular,the OCTs in the liver and in the intestine have been proposed as important determinants of drug absorption and disposition.Over the past several decades,the mechanisms of organic cation transport have been extensively characterized using in vivo models,ex vivo organ perfusions,in vitro tissue preparations and cell lines.In particular,the molecular cloning and characterization of OCTs have remarkably increased our knowledge of this important subfamily of solute carriers.In this article,we first review the molecular cloning and characterization of OCTs.We will then describe their transport mechanisms,tissue distribution and localization,and their specificity of interaction with organic cations.Regulatory mechanisms and genetic animal models will be reviewed as they provide the most important insight on this class of transporters in recent years.Finally,we will summarize genetic variation in human OCT genes and raise clinical perspectives on these important transporters.

Objective This study is to conduct an overall assessment of social function of elderly pa-tients with urinary incontinence (UI) and the factors that affect the social function exactly. Thus, some nurs-ing intervention can be put forward for the patients. Methods The investigation was carried out with inter-national consultation on incontinence questionnaire short form (ICI-Q-SF), incontinence quality-of-life scale (I-QOL) and social disability screening schedule (SDSS). Results The mean score of SDSS of patients was 4.0, this score was between patients with neurosis and patients with mental illness. The number of elderly pa-tients with UI investigated in this research who had social disability was 90. The incidence of social disability was 81.82%. Age and UI were the main factors affecting the social function of elderly patients with UI. There was significant correlation between social function and quality of life, the more serious of social disability, the poor of life quality. Conclusions Significant social disability exists in the investigated elderly patients with urinary incontinence. Some effective nursing interventions must be taken to improve the situation and increase their survival quality.

The development of cancer gene vaccineis gradually maturing,common genes mainly include cytokine gene vaccines,multi-gene combined vaccines,gene-transfered dendritic cell vaccines,and so on.In re-cent years the development of cancer gene vaccines gradually tend toward looking for gene vaccine adjuvants,or exploration of the combination of different genes to achieve a more effective therapeutic purposes.

Objective To evaluate the nursing methods of patients with ischemic cerebrovascular disease treated by intracranial stent. Methods 90 patients with ischemic cerebrovascular disease in our hospital during March 2006 to March 2010 were selected, their clinical nursing measures were summarized. Results All patients passed the treatment process, mean hospital stay was ( 19.8 ± 4.0)days. Conclusions Elaborate nursing to patients with ischemic cerebrovascular disease treated by intracranial stent can effectively reduce the average length of hospital stay.
