ObjectiveTo investigate the quality of life (QOL) of old patients with cardiovascular diseases in community. Methods100 old patients with cardiovascular diseases in Xiluoyuan, Beijing were investigated with WHOQOL-BREF. ResultsThe QOL-BREF scores in the dimensions of physical health, psychology, social relationships, and environment were (53.21±11.50), (53.27±15.99), (54.29±14.41) and (57.65±15.30) respectively. There was not significant difference between self-rating scores and scores in four dimensions of QOL-BREF (P>0.05). There was not significant difference of QOL-BREF scores in four dimensions between male and female, nor the ones whether complicated with diabetes (P>0.05). The incidence of satisfaction was 31% for QOL, 23% for health, and 62% for the healthy system as self-report. ConclusionThe QOL of the patients is related to diseases.

BACKGROUND:Tol-like receptor (TLR) and its signaling pathway play an important role in autoimmune diseases, hypersensitivity, inflammation, apoptosis and transplant rejection; however, its effects on immune pathogenesis of Henoeh-Schonlein purpura in children have not been fuly elucidated. OBJECTIVE:To investigate the TLR2 expression in peripheral blood mononuclear cels in children with Henoeh-Schonlein purpura and its correlation with immune response. METHODS: Sixty-four children with Henoeh-Schonlein purpura were divided into two groups: non-renal damage group (n=36) and renal damage group (n=28). Meanwhile, another 30 healthy children subjected to health examination acted as control group. Flow cytometry and florescent quantitative PCR were employed to detect TLR2 protein and mRNA expression in peripheral blood mononuclear cels, respectively. ELISA was used to detect plasma interferon-γ and interleukin-4 levels and transforming growth factor β and interleukin-10 levels secreted from Treg cels. RESULTS AND CONCLUSION:Levels of interferon-γ and interferon-γ/interleukin-4 in the children with Henoeh-Schonlein purpura were significantly lower than those in the control group (P < 0.05), while the level of interleukin-4 was higher than the control group (P < 0.05). The expression of TLR2 protein and mRNA was significantly higher in the Henoeh-Schonlein purpura children than the healthy children (P < 0.05) and significantly higher in the renal damage group than the non-renal damage group (P < 0.05). Compared with the control group, the levels of interleukin-10 and transforming growth factor β were significantly higher in the children with Henoeh- Schonlein purpura (P < 0.05). These findings indicate that Henoeh-Schonlein purpura children have increased levels of TLR2 protein and mRNA in the peripheral blood mononuclear cels, and exhibit immune imbalance. TLR2 is involved in the pathogenesis of Henoeh-Schonlein purpura, and transforming growth factor β can be used to evaluate Treg immune response and provide reference for diagnosis, treatment of prognosis of Henoeh-Schonlein purpura children.

Acidolysis kinetics on the process of the hydrolysis acidification by using glucose as the only energy sources was researched.It was concluded that the acidolysis kinetics constants are V_(max)=8.45d~(-1) and K_s=1089mg/L,under the circumstances of a temperature 37℃?0.5℃and the influent pH value 6.5.The results show that the rate of anaerobic acidification process is greater than that of completed an- aerobic or anoxic process.

Objective To investigate correlation between post-stroke depression (PSD) and multiple factors during onset of acute cerebral infarction. Methods Depression was measured with Hamilton Depression Rating Scales (HAMD) in 58 patients with acute cerebral infarction, and their neurological function were evaluated by neurological function defect (NFD) score. Their immunoglobulin G (IgG) index was calculated and level of nitric oxide (NO) in cerebrospinal fluid (CSF) was measured. Lesion and nature of cerebral infarction in 58 patients with acute stroke were located by CT. All the data were statistically analyzed with student-t test and ? 2 test, as well as linear regression model. Results Seventeen of 58 patients of stroke appeared PSD with an occurrence rate of 29.3%. Occurrence rate of PSD was significantly higher in patients with cerebral infarction than in those with cerebral hemorrhage  2=4.86, P

OBJECTIVE:To evaluate the research of antidepressive agents from the literatures perspectively in order to develop antidepressive agents in China.METHODS:The literatures about antidepressive agents recorded in PubMed database from Jan.1st,1998 to Oct.31th,2008 were analyzed with bibliometric methods.RESULTS:A total of 17784 literatures on antidepressive agents were recorded and the total number increased slowly.A total of 96 literatures were collected from Chinese literatures which increased rapidly in recent years.34 literatures among 74 literatures during 1998～2007 are in English and 40 in Chinese involved 56 institutes and 51 magazines.Literatures collected from Beijing took up the greatest proportion.CONCLUSION:It is needed to enlarge investment and scale of scientific research on antidepressive agents continuously.

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 investigate the clinical phenotype, genotype and ultrastructural features in a pedigree with autosomal recessive congenital ichthyosis. Methods Patients were examined for clinical manifestation. PCR was carried out to amplify all the 15 exons and adjacent splice sites of TGM1 gene followed by bidirectional sequencing. Skin samples were taken by biopsy from the back of the proband, fixed in 3% glu-taraldehyde for transmission electron microscopy. Results The proband presented an intermediate clinical phenotype between lamellar ichthyosis (LI) and non-bullous congenital ichthyosiform erythroderma (NCIE), while his brother manifested as a collodion baby. A C551T heterozygous mutation which located in the third exon of TGM1 gene and resulted in a substitution of arginine by cysteine at codon 143 (R143C), was detected in the proband, his brother and father. Meanwhile, another heterozygous C-to-T transition at position 759 causing a substitution of serine by phenylalanine at codon 212 (S212F), was noted in the proband, his brother and mother. Electron microscopy revealed not only features of ichthyosis congenital type Ⅲ but also those of ichthyosis congenital type Ⅱ in lesions of the proband. Conclusions The patients in this pedigree carry compound heterozygous mutations, i.e. R143C, a hot missense mutation, as well as a de novo mutation S212F. The proband, who harbors mutations in the TGM1 gene, shows electron microscopic features characteristic not only of ichthyosis congenital type Ⅱ but also of ichthyosis congenital type Ⅲ.

Objective To assess the characteristic of left ventricular(LV) twist changed from infancy to the elder,in order to determine the normal value of LV twist in different age group.Methods After acquired basal and apical LV short-axis images in 293 healthy volunteers (aged 15 days to 72 years) by 2-dimensional echocardiography, speckle tracking echocardiography was used to analysis LV twist motion offline.The peak apical rotation (PAr), peak basal rotation (PBr), peak LV twist (Ptw), peak LV twist normalized by LV length ( PtwN), peak untwisting velocity ( PutwV), isovolumic untwisting% ( Iutw% ) in different group were compared.Results Reliable LV twist measurements were obtained in 274 volunteers.Different LV twist values were noted according to age.Ptw increased gradually with advancing age, when normalized by LV length, PtwN showed higher values before 3 years old and 25 to 45 years old.PutwV increased with aging from infancy to 25 years old, and leveled off from 25 to 45 years old, then decreased with advancing age.Iutw% was lowest before 3 years old,and increased gradually from 25 to 45 years old,then decreased with aging.Conclusions speckle tracking echocardiography can be used to noninvasively and exactly assess LV twist with high feasibility.The effect of aging on LV twist may reflect the process of maturational and adaptive modulation of LV torsional biomechanics from infancy to the elder.
