Objective To explore the effect of community comprehensive rehabilitation on quality of life in patients with stroke sequelae under the family medical service mode. Methods From October, 2013 to October, 2014, 51 patients with stroke sequelae received compre-hensive rehabilitation intervention for three months, including rehabilitation training, rehabilitation guidance, health education and psycho-logical counseling. They were assessed with modified Barthel index (MBI), WHO-Disability Assessment Schedule (WHO-DASⅡ), Short Form 36 Health Survey Questionnaire (SF-36), Brain Injury Community Rehabilitation Outcome Scales (BICRO-39), Self-rating Anxiety Scale (SAS), Self-rating Depression Scale (SDS) before and after intervention. Results The scores of physical functionning, role physical, general health, mental health, social functioning and the total score in SF-36 increased after intervention (t>2.072, P<0.05). The scores of so-cial contact, locomotivity, self handling transaction ability and the total score in BICRO-39 decreased after intervention (t>2.434, P<0.05), as well as the scores of getting along with people, housework and society and participation in WHO-DAS II (t>2.507, P<0.05). Conclusion In the community health service, comprehensive rehabilitation guided by multidisciplinary rehabilitation team can facilitate to improve the quality of life in patients with stroke sequela.

Objective To explor the value of Tei index for evaluation the cardiac function of patients with chronic heart failure(CHF).Methods Tei index in 60 patients with CHF(CHF group) and 30 normal controls(control group) were evaluated and compared with the levels of NT-ProBNP and the NYHA class,and the sensitivity and specificity of Tei index for CHF diagnosis were appraised.Results (1) Tei index in CHF group was significantly higher than that in control group.When Tei index was more than and equal to 0.45,the sensitivity,specificity,positive predictive value,and negative predictive value of Tei index for diagnosing CHF were 85.6％,90.4％,89.8％ and 78.0％.(2)There was a remarkable positive correlation between Tei and Log NT-ProBNP(r =0.84,P ＜ 0.01).(3)There were significant differences in Tei index among NYHA Ⅱ,Ⅲ,Ⅳ class [(0.47 ± 0.06),(0.56 ± 0.08),(0.64 ±0.13)].Conclusion Tei index can be used to diagnose CHF and evaluate the degree of it.

Objective To explore the effects of repetitive transcranial magnetic stimulation (rTMS) on the motor function of lower limbs of patients with cerebral infarction.Methods Sixty stroke survivors with lower limb dysfunctionwere randomly assigned to an rTMS treatment group or a control group,each of 30.Both groups were given routine medication and rehabilitation treatment,while the treatment group was additionally provided with 4 weeks of rTMS treatment of the contra-lesional M1 at 1 Hz and 90％ motor threshold.The Fugl-Meyer motor assessment (FMA) and maximum walking speed (MWS) were used to assess both groups before and after the treatment and 2 weeks later.Adverse reactions were also recorded.Results Before the intervention,no differences were found between the two groups.After the treatment and two weeks after that,significant improvement was observed in the average FMA and 10 m MWS of both groups,with significantly more improvement in the treatment group than among the controls.No obvious adverse reactions were observed in either group.Conclusions rTMS can improve the motor function of the affected lower limbs of stroke patients safely.

Background:Accumulating evidence links colorectal cancer (CRC) with the gut microbiota.Fusobacterium nucleatum (F.nucleatum) has been revealed to be involved in the development of CRC, however, the mechanism of F.nucleatum in mediating colorectal tumorigenesis is still poorly understood.Aims:To investigate the effect and potential mechanism of F.nucleatum on CRC.Methods:Wild type C57BL/6 mice and APC(Min/+) mice characterized by multiple intestinal neoplasia were used in this animal study.After administered with F.nucleatum intragastrically and/or 1,2-dimethylhydrazine (DMH, a carcinogen) subcutaneously, the aberrant crypt foci (ACF) and colonic tumor were counted at 8th and 20th week, respectively.Structural alteration of intestinal microbiota and mucosal immune factors were detected in wild type C57BL/6 mice receiving different interventions by using Roche 454 GS FLX pyrosequencing and Bio-Plex ProTM cytokine assay, respectively.Results:In DMH-treated wild type C57BL/6 mice or APC(Min/+) mice, number of ACF and colonic tumor in those administered with F.nucleatum were significantly higher than those without (P<0.05).F.nucleatum colonization significantly altered the lumen microbial structure, with decreased Cyanobacterium and increased Tenericutes and Verrucomicrobia (P all <0.05).Furthermore, F.nucleatum up-regulated expressions of tumor-related immune factors in colonic mucosa, such as IL-21, IL-22, IL-31 and CD40L (P<0.05).Conclusions:F.nucleatum colonization in intestine may prompt colonic tumorigenesis in mice via inducing intestinal dysbiosis and modulating tumor-related immune factors expression.

In order to authenticate the components of antler powder in the market, DNA barcoding technology coupled with cloning method were used. Cytochrome c oxidase subunit I (COI) sequences were obtained according to the DNA barcoding standard operation procedure (SOP). For antler powder with possible mixed components, the cloning method was used to get each COI sequence. 65 COI sequences were successfully obtained from commercial antler powders via sequencing PCR products. The results indicates that only 38% of these samples were derived from Cervus nippon Temminck or Cervus elaphus Linnaeus which is recorded in the 2010 edition of "Chinese Pharmacopoeia", while 62% of them were derived from other species. Rangifer tarandus Linnaeus was the most frequent species among the adulterants. Further analysis showed that some samples collected from different regions, companies and prices, contained adulterants. Analysis of 36 COI sequences obtained by the cloning method showed that C. elaphus and C. nippon were main components. In addition, some samples were marked clearly as antler powder on the label, however, C. elaphus or R. tarandus were their main components. In summary, DNA barcoding can accurately and efficiently distinguish the exact content in the commercial antler powder, which provides a new technique to ensure clinical safety and improve quality control of Chinese traditional medicine
