Sixty patients with dysphagia following the acute stroke were enrolled and divided into training group and control group with 30 cases in each group.Both groups received the routine medication,but patients in training group had additional swallowing rehabilitation training.After 4 weeks,the recovery rate of swallowing function in training group was higher than that in control group [ 93 ％ (28/30) vs.63 ％(19/30),P ＜ 0.05 ] ; the incidence rate of aspiration pneumonia in training group was lower than that in control group[ 3.3％ ( 1/30 ) vs.26.7％ ( 8/30 ),P ＜ 0.05 ].The results showed that swallowing training applied to acute stroke patients with dysphasia may promote the recovery of swallowing function,reduce the complications and improve their quality of life.

Objective To explore the effect mechanism of sympathetic nerve on early developing embryo of mice. Methods The model of sympathectomy mouse was established by 6-OHDA injected intraperitoneally.The early developing mice embryo and lymphocytes in uterus were observed using histology,immunohistochemistry and ELISA methods. Results In sympathectomy mouse,the number of embryo implantation was decrease to 64.4%,endometrial lamina propria and vascellum were shortfall.The numbers of CD4~+T cell and CD8~+T cell in sympathectomy mice were larger than ones in control groups,especially,the number of CD8~+T cells at E3 and E5 differed highly(P

Jaundice is a common clinic presentation which can be caused by various benign or life-threating disorders.Charaterization by unconjugated(indirect)hyperbilirubinemia and conjugated(direct)hyperbilirubinemia may help clinic diagnosis and treatment.The reasons causing unconjugated hyperbilirubinemia include hemolytic anemias,ineffective hematopoiesis,malfunction of bilirubin absorption and combination by hepatocytes or hyperbilirubinemia after hepatitis.Moreover,liver excretion disfunction by inherited disease,hepatocellular jaundice,or various obstruction of the duct system can lead to conjugated hyperbilirubinemia.This article discusses the category of jaundice according to different serum bilirubin,which warrants to clarify the cause quickly so that treatment can begin as soon as possilble.

From the characteristics of nursing ethics and be-havior dynamic analysis, suggest to establish a focus on the humanities concern nursing ethics culture of the people-oriented, fundamentally effectively motivate nurses, specific include: respecting nurses and ethical personality differences;to establish a trust mechanism for nursing staff;meet the needs of nursing staff learning;to establish a nursing staff self management team, thus improve hospital nursing ethics management work, for the nursing staff to provide a stable and efficient working and living environment.

OBJECTIVE:To discuss the research and clinical application of drug eluting stents,in addition,to explore the effects of drug eluting stents on preventing and curing coronary restenosis. METHODS:The databases of Medline and Chinese CNKI were retrieved using computer from 1993 and 2009,and the literature was selected according to inclusion and exclusion criteria. The rapamycin eluting stent and paclitaxel eluting stent were widely used in preventing and curing in stent restenosis,the problems existed in this process were discussed. RESULTS:Drug eluting stents could prevent in stent restenosis following stent implantation,however,the problems such as poor adherence or stent fracture still occurred in clinic. CONCLUSION:Drug eluting stents exhibit efficiency and safety in preventing restenosis,but there still existed problems need to further explore.

Objective:To investigate costimulatory molecules and adhension molecules in the pathogenesis of experimental colitis in rats.Methods:Models of experimental colitis were established by enema with trinitrobenzenesulphonic acid. Prednisolone or salicylazosulfapyridine was given as treatment.Nomal rat and untreated colitis rat groups were set up as controls.Histological scoring was performed.Expression of CD11b,CD28 and CTLA-4 were detected by flow cytometry in peripheral blood,spleen and intraepithelial mononuclear cells of colon.Results:Expressions of CD11b,CD28 and CTLA-4 were high in experimental colitis. CD11b and CD28 decreseased after treatment of prednisolone or salicylazosulfapyridine,while CTLA-4 increased further,which were significant statistically.Conclusion:Adhesion molecules may have a role in the pathogenesis of experimental colitis.The dysregulation of CD28 and CTLA-4 may be one of the mechanisms in IBD.The mechanisms of prednisolone and salicylazosulfapyridine may be associated with costimulatory molecules and adhension molecules.

Objective To analyze the clinical characteristics of ulcerative colitis (UC) in elderly patients.Methods A total of 166 cases with diagnosed UC were recruited.The clinical characteristics were compared between the elderly group (n=35,≥60 years) and the young group (n =131,20 59 years).Results The number of male patients were more than female patients in both groups.The incidence of abdominal pain was significantly lower in the elderly group than in young group (P＜0.05).The number of severe patients were significantly lower in the older group than in young group.Severe UC prevalence was 27.5％ (36 cases) in the young versus 11.4％ (4 cases) in the elderly (x2 =3.89,P＜0.05).The prevalence of total colitis was lower in elderly group than in younggroup [31.4％ (11 cases) v,.51.1％ (61 cases),~ =4.31,P＜0.05],however,the prevalence of proctitis is more common in the elderly than in young group.The extra-intestinal manifestations and the ratio of receiving immune inhibitor and operation showed no significant differences between the two groups.Conclusions Compared with young group,there are a lower incidence of abdominal pain,a higher number of severe patients,a lower incidence of total colitis,and a higher incidence of proctiits in elderly group.

Objective To observe interference effect of Ambroxol (AMB) hydrochloride injection on chronic obstructive pulmonary disease in rats caused by cigarette smoking exposure.Methods Chronic obstructive pulmonary disease (COPD) rat models were established by simple cigarette smoking exposure,interfered with AMB inhalation.Rats were divided into three groups.Cell counts were examined routinely in bronchoalveolar lavage fluid (BALF).The concentrations of Matrix metalloproteinase-9(MMP-9)、interleukin-8 (IL-8) and tumor necrosis factor-? (TNF-?) in BALF were measured.Quantitative analysis of pulmonary mean linear intercept (MLI),mean alveolar numbers (MAN),pulmonary alveolar area (PAA) and the relative area of elastic fibers were measured.Results Concentrations of MMP-9,IL-8 and TNF-? in BALF of COPD rats were positively correlated with total counts of white blood cell (WBC),percentage of neutrophil and absolute counts of neutrophil in BALF.Pulmonary elastic fibers were severely damaged in COPD rats;MLI,PAA were higher than those in control group (P0.05).Conclusion Simple cigarette smoking can cause COPD in rats.MMP-9,IL-8 and TNF-? in airway and alveoli pulmonum probably participate in the destruction of elastic fibers and forming of COPD.AMB inhalation can inhibit release of IL-8 and TNF-? in airway and alveoli pulmonum of COPD rats,alleviate the inflammation of local airway caused by cigarette smoking,playing a role in preventing and curing experimental COPD of rats.
