Frailty is an important problem influencing the health of elderly.Frailty syndrome assessment is helpful to identify the frailty status and to enhance the targeted intervention.This paper mainly reviewed the research progress of frailty syndrome tools for the elderly abroad,so as to provide evidence for developing specific frailty syndrome assessment tool for Chinese elderly people.

Objective To explore the prevalence and relationship of urinary incontinence and depression among elderly female patients.Methods A total of 118 female patients older than 60 years old were interviewed face to face.The prevalence of urinary incontinence and depression were estimated using the International Consultation on Incontinence Questionnaire Urinary Incontinence Short Form-Chinese (ICIQ-SF-Chinese) and Geriatric Depression Scale-15 (GDS-15).Linear regression and Spearman correlation were used to identify the relationship between urinary incontinence and depression.Results Urinary incontinence was found in 27.1％ (32/118),and depression was in 39.0％ (46/118) of the survey population.Urinary incontinence with depression was found in 13.6％ (16/118) of the overall population.Urinary incontinence was positively correlated with depression,r=0.211,P＜0.05.The frequency of entertainment and urinary incontinence were significantly related to depression symptoms,P＜0.05.Conclusions Urinary incontinence appears to possess an additive effect on incidence of depression,which seriously affects both physical and mental health of patients.Clinicians should give patients health education and intervention measures at early stage.

Objective To investigate the current status about nursing undergraduate students' knowledge,attitude and practice (KAP)regarding nosocomial infection.Methods The self-administered questionnaires were employed to survey 108 undergraduate nursing students on the basis of a simple random sampling method.Results In the knowledge dimension,the nursing students earned 78.3％ of accuracy rate when responding to the questionnaires.The students also demonstrated positive attitudes towards nosocomial infection and occupational safety,particularly the female students.In terms of practice,the students performed relatively poor as 36.1％ of the students were unclear about the classification of medical garbage and 22.2％ of the students used their non-clean hands to touch their eye-glasses.Conclusions The undergraduate nursing students have demonstrated adequate knowledge and proper attitude towards nosocomial infection and occupational safety,however,some behaviors need to be changed.Nursing schools and hospitals should be aware of these findings and provide more training programs regarding nosocomial infection and occupational safety so that they can help students formulate good habits to prevent and control nosocomial infection.

Aim To investigate the effects of 3 ,5 ,2 ’ , 4’-tetrahydroxychalcone (P40) on urate excretion, as well as mRNA and protein expressions of renal URAT1 and GLUT9 in hyperuricemic mice. Methods Sixty Kunming mice were randomly divided into six groups:normal control group, hyperuricemic group ( model group), P40 2. 0, 4. 0, 8. 0 mg·kg-1 groups and positive control group. All drugs were administered in-tragastrically to mice for 5 doses. Hyperuricemic mice were induced by intraperitoneal injection of uric acid (0. 15 g·kg-1 body weight) for 3 times. The urate levels were assayed with the phosphotungstic acid method. The mRNA and protein expressions of GLUT9 and URAT1 were determined by RT-PCR and Western blot. Results P40 at a dose of 4. 0 and 8. 0 mg · kg-1 significantly reduced the serum urate levels in a dose-dependent manner, when compared with untreat-ed hyperuricemic mice ( P<0. 05 or 0. 01 ) . The he-patic urate contents decreased in untreated-and treated-hyperuricemic mice as compared with normal mice ( P<0. 01 ) . Furthermore, P40 had no influence on the renal URAT1 mRNA and protein expression levels, while it could down-regulate renal GLUT9 protein ex-pression but not mRNA expression in hyperuricemic mice. Conclusion P40 possesses potent uricosuric effects associated with urate reabsorption by down-regu-lating the protein expression of GLUT9 in kidney.

Objective To determine the audiological characteristics in 832 deaf children with biallelic causative mutations in GJB2 ,SLC26A4 gene .Methods The 832 patients received deafness gene screening ,553 were GJB2 gene biallelic causative mutations ,279 were SLC26A4 gene biallelic causative mutations .Patients were divided into four groups according to ages of hearing loss onset :<1 ,1~3 ,3~6 ,6~12 years old ,and the audiological character-istics and prevalence of GJB2 ,SLC26A4 gene mutations at different ages of onset .Results The prevalence of GJB2 gene mutations at four groups was 37 .97% (210/553) ,38 .34% (212/553) ,16 .27% (90/553) ,7 .41% (41/553) ,re-spectively ;the prevalence of SLC26A4 gene mutations at four groups was 25 .45% (71/279) ,44 .80% (125/279) , 20 .07% (56/279) ,9 .67% (27/279) ,respectively .The difference between GJB2 and SLC26A4 gene was significant(P=0 .001) .The prevalence of profound hearing loss with GJB2 gene mutations at four groups were 66 .67% (140/210) ,61 .32% (130/212) ,47 .78% (43/90) ,41 .46% (17/41) ,respectively .The difference was significant (P=0 .004) ,while the difference in 279 patients with SLC26A4 gene mutations was not statistically significant (P= 0 . 083) .Conclusion The age of hearing loss onset in patients with biallelic causative mutations in GJB 2 or SLC26A4 gene refers to 0~3 years -old ,hearing loss in patients with GJB2 ,SLC26A4 gene mutations gives priority to pro-found .The age of hearing loss onset is smaller ,the ratio of profound hearing loss is higher .Patients with severe and profound hearing impairment should be performed the genetic testing when the age of onset under 12 .

Objective To evaluate the changes of the right atrium,right ventriculum,left atrium and left ventriculum after transcatheter closure of atrial septal defect(ASD) during a short to mid-term follow-up.Methods The right ventricular end-diastolic anterior-posterior diameter(RVEDD),right atrial long diameter(RADl),right atrial transverse diameter(RADt),left ventricular end-diastolic ante-posterior diameter(LVEDD),left ventricular end-diastolic volume(LVEDV) and left atrial anterior-posterior diameter(LAD) in 36 patients with secundum ASD were measured before ASD closure,after 3 days,3 months and 6 months of ASD closure with transthoracic echocardiography(TTE).Results RVEDD,RADl and RADt were significantly decreased,while LVEDD,LVEDV and LAD significantly increased 3 days after ASD closure.During 3 months follow-up,RVEDD,RADl and RADt continuously became smaller;LVEDD,LVEDV and LAD continuously became larger.At 6 months,RVEDD was significantly smaller and LVEDD,LVEDV were significantly larger than those at 3 months.No remarkable difference of RADl,RADt and LAD was found between 6 months and 3months follow-up.Conclusion Transcatheter closure of ASD not only decreases the preload of right heart and causes right atrium and right ventriculum become smaller,but also improves the geometry of left heart and causes the narrowed left atrium and left ventriculum gradually return to almost normal status.

Objective To explore the attitude and knowledge towards elderly among undergraduate nursing student , and to investigate the factors which influencing their willingness to work with elderly . Methods A total of 112 freshmen and junior nursing students were chosen by convenience method as sample in one university and surveyed by demographic questions , the Kogan′s Attitude toward Older People ( KAOP) and the Palmore′s Facts on Aging Quiz 1 ( FAQ 1).Results 85.7% of participates had not learned the aging knowledge systematically , and 75.0% presented interest in aged people while 65.2% showed willingness to work for elderly .All students showed a positive attitude towards elderly ( KAOP >102 ) , and the freshmen acquired (145.5 ±11.3) scores while junior students gained (132.9 ±11.9) scores (t=5.6,P<0.05). Meanwhile, freshmen obtained (12.0 ±2.3) scores for the knowledge of aging whilst junior students achieved (12.9 ±2.5) scores (t=-2.0,P<0.05).The age of students had positive correlation with the knowledge of aging, but negative correlation with attitude towards elderly (r =0.231, -0.374,respectively;P <0.05). Students who were more interested in elderly showed more willingness to work for elderly (r=0.314,P<0.01). Conclusions Undergraduate nursing students have a positive attitude towards elderly , and have shortage of aging knowledge , which implied that we should change the curriculum model to improve the right view and interest toward elderly , and cultivate more excellent geriatric nursing students .
