Frailty is a pre-disabled stage and associated with increased vulnerability to adverse health outcomes. Frailty has high preva-lence in older population. There are 2 principal emerging models of frailty, which are the phenotype model and the frailty index model. Many studies have developed tools to detect frailty, including self-report scales, such as PRISMA-7, Groningen Frailty Indicator (GFI), Ed-monton Frail Scale (EFS) and Simple Frailty Questionnaire (FRAIL);and single assessments, such as gait speed, timed up-and-go test, grip strength, pulmonary function test. Intervention of exercise and/or nutrition are benefical for frail older adults.

Liver metastasis is the leading cause of death from colorectal cancer.Surgical treatment is so far the best choice for the treatment of colorectal liver metastases (CRLM).However,how to suitably select an individualized chemotherapy in perioperative period and surgical time and tool is still under controversy.Therefore,the key factors of improving the prognosis of patients with CRLM include overall evaluation of the patients and their preoperative examination outcomes,dividing patients into different groups based on different therapeutic goals,understanding different therapeutic goals of each group,selecting suitable chemotherapy and targeted therapy,ensuring surgical time (synchronous or stepwise resection) and tools (minimally invasive or open surgery) through multidisciplinary team model.

Objective To observe the effects of Donepezil on cognitive function of delyed ephalophthy after acute carbon monoxide poisoning ( DEACMP) .Methods Eighty patients with DEACMP were randomly divided into control group ( 40 cases ) and treatment group ( 40 cases ) .The control group was given treatment of regular medicine, placebo and hyperbaric oxygenation.The treatment group was given treatment of regular medicine, Donepezil and hyperbaric oxygenation.The dose of Donepezil was 5.0 mg per night, and 90 d was a period of treatment.The cognitive function of patients was evaluated respectively by MMSE and Barthel Index rating scale ( BI) .And the results were compared between the two groups.Results Compared with before treatment, the MMSE and BI scores of the two groups after treatment were significantly increased (P<0.05 -0.01).And after the treatment, the MMSE and BI scores of the treatment group were significantly higher than those in the control group (P<0.05-0.01).Conclusion Donepezil can greatly improve the cognitive function of DEACMP patients, it is worthy to be clinical promoted.

Objective To explore the effect of brief group psychological counseling in promoting students psychological health of high grade in primary school. Methods Two classes were randomly selected from a primary school in a community of Pudong New Area in Shanghai from October 2014 to November 2014, with stratified cluster sampling method in 4,5 grade ( the boy 30, the girl 24) as the research object, the other 2 classes (4,5 grade 1 classes;the boy 25,the girl 31) of students as control group, in the intervention group students brief group counseling was carried out, while the control group received the routine psychological health education course. Using the mental health diagnosis test (MHT) as a psychological assessment tool, MHT scores of two groups of students and factors were analyszed by the test analysis. Results Before intervention, the intervention group and the control group in the mental health diagnosis test (MHT) had no significant difference in each factor (P>0.05). After the intervention, significant were found differences between the intervention group and the control group in MHT learning anxiety, anxiety to people, self accusation tendency, allergic tendency, body symptom, terror tendency and the total score(6.46±3.01, 8.59±3.40; 3.04±1.91, 4.45±2.43; 3.56± 2.13, 5.30 ± 2.10; 4.37 ± 1.93, 5.84 ± 2.63; 3.76 ± 2.82, 5.46 ± 3.38; 2.15 ± 2.34, 3.91 ± 3.00; 32.44 ± 13.07, 44.52±17.59)(t=-3.47、-3.38、-4.30、-3.35、-2.87、-3.40、-4.10 ,P<0.05), and the average scores in the intervention group of each factor were lower than those of control group. Conclusion Brief group psychological counseling for higher-grade students of elementary school learning anxiety group, had better interventional effect on anxiety, self-blame tendency, the overall tendency of anxiety and other fields. It will have a positive impact on the allergic tendency, body symptom, terror tendency and other fields; it needs further evaluation in large sample for long-term effect.

Objective To observe the influence of cervical traction and manipulation on hemorheology of cervical vertigo patients.Methods 59 patients in outpatients of our hospital from January 2012 to August 2013 were recruited and divided into a control group(29 patients)and a treatment group(30 patients)randomly. The control group was treated with flunarizine, and the treatment group was additionally treated with cervical traction and manipulation on the basis of the control group. After 4 therapeutic causes, evaluation of cervical vertigo symptoms and functions(ESOV)were performed and hemorheological changes were observed in both groups.Results① ESOV comparison: ESOV sores in both groupswere obviously improved after the treatment than the same group before the treatment(t=11.028, 5.825,all P<0.01)the treatment group were significantly lower than that in the control group after treatment(t=3.6057,P<0.01).② hemorheology changes comparison: whole blood viscosity(high-, medium- , low shear), whole blood reduction viscosity, erythrocyte aggregation index, hematocrit in the treatment group were improved obviously after the treatment than before(t=3.356, 13.245, 3.650, 7.443, 9.912, 3.113,P<0.05 orP<0.01). The whole blood viscosity(high-, medium-shea), blood reduction viscosity, erythrocyte aggregation index in the control group were obviously improved than the before(t=2.144, 4.216, 3.287, 3.039, 6.442,P<0.05 orP<0.01). The difference between the two groups were also obvious after the treatment(P<0.05 orP<0.01).Conclusions Cervical traction and manipulation combined with flunarizine can elevate ESOV score, improve hemorheology and therapeutic effect in patients with cervical vertigo.

The procedure of occlusal treatment involves improving the morphology and the stomatognathic function.Several practical methods and morphological endpoints have been described in occlusal rehabilitation.We made a selection of these (mandibular position,oc-clusal plane,occlusal guidance,occlusal contact,face-bow transfer,use of an adjustable articulator and occlusal support)and performed a literature review to verify the existence of compelling scientific evidence for each of these.A literature search was conducted using Medline /PubMed in March 2011.Over 400 abstracts were reviewed,and more than 50 manuscripts selected.An additional hand search was also con-ducted.Of the many studies investigating stomatognathic function in relation to specific occlusal schemes,most studies were poorly designed and of low quality,thus yielding ambiguous results.Overall,there is no scientific evidence that supports any specific occlusal scheme being superior to others in terms of improving stomatognathic function,nor that sophisticated methods are superior to simpler ones in terms of clini-cal outcomes.However,it is obvious that the art of occlusal rehabilitation requires accurate,reproducible,easy and quick procedures to re-duce unnecessary technical failures and /or the requirement for compensatory adjustments.Therefore,despite the lack of scientific evidence for specific treatments,the acquisition of these general skills by dentists and attaining profound knowledge and skills in postgraduate training will be necessary for specialists in charge of complicated cases.

Objective To study the correlation between diabetes and the new discovered angiopietin-related growth factor (AGF)that participates in energy metabolism.MethodsA total of 24 male C.57BL/6 mice were divided into three groups:controlled group; fed with high-fat diet( HFD); fed with high-fat diet for 10 weeks and then treated with rosiglitazone ( HFD + RSG) ; The relative level of AGF mRNA expression in livers was measured by determining a ratio of PCR products of AGF to that of β-actin gene.Oral glucose tolerance test,and insulin resistance index (HOMA-IR) were used to measure blood glucose level and insulin sensitivity.Results Compared with the controls,the expression of AGF mRNA in liver decreased significantly in HFD group( P ＜0.05),and increased significantly in HFD + RSG group( P＜0.01 ).A negative correlation was found between AGF mRNA expression in mice livers and HOMA score ( r =-0.516,P ＜ 0.05 ).Conclusions AGF as a new hepatocyte derived circulating factor counteracts obesity and is related to insulin resistance.
