Objective To explore the relationship between self-efficacy and health behavior among stroke survivors.Methods Self-efficacy for Managing Chronic Disease 6-item Scale and Health Promoting Lifestyle Profile II were used to measure 96 stroke survivors’ self-efficacy and health behaviors.Pearson correlation analysis was used for the analysis of correlation.Results The mean score of overall health behaviors was (2.41±0.33).Pearson’s correlation coefficient between self-efficacy and health behavior was 0.36 (P<0.05).Conclusions The health behaviors of stroke survivors were at the intermediate or lower level and their self-efficacy was at the intermediate level.In order to help stroke survivors to improve their health behaviors,self-efficacy should be enhanced by specific health education.

This study is to report the preparation of complexes of Ad5 and anionic liposomes (AL-Ad5), the amplification of adenoviruses with enhanced green fluorescent protein (eGFP) reporter gene performed by HEK 293 cells, the adenoviral vectors purified by cesium chloride gradient centrifugation, and the titer of adenovirus determined by cytopathic effect (CPE) method, hexon capsid immunoassay and quantitative-PCR (Q-PCR), separately. The prescription and experiment conditions were optimized by central composite design (CCD). The complexes of Ad5 and AL-Ad5 were formulated by the calcium-induced phase change method. The morpholopy, particle size and zeta potential were detected by dynamic light scattering (DLS) and transmission electron microscopy (TEM), respectively. Additionally, the bicolourable fluoresce-labeled complexes (F(labeled)-AL-Ad5) were prepared and their intracellular location in MDCK cells was detected by confocal laser scanning microscopy (CLSM). The results indicate that the complexes of AL-Ad5 exhibited a uniform distribution with a particle size of 211 +/- 10 nm and a zeta potential of -41.2 +/- 2.2 mV. The result of CLSM demonstrates that the intracellular location of red fluoresce-labeled adenovirus was consistent with that of green fluoresce-labeled liposomes suggesting that the naked adenovirus was well encapsulated by the anionic liposomes in complexes of AL-Ad5.

Objective:To analyze the molecular characteristics of dengue virus (DENV) strains circulating in Shantou city in 2018 and 2019 for elucidating the reasons causing strikingly different dengue fever epidemics during the two years and understanding the transmission characteristics and routes of DENV, and to provide reference for the prevention and control of dengue fever.Methods:Detection of viral nucleic acid contents and amplification and sequencing of E gene were carried out on 872 samples positive for DENV acid in 2018 and 2019. Phylogenetic trees were constructed based on the E gene sequences to analyze the homology of DENV strains. The sources and transmission routes of the strains were also analyzed. Results:A total of 99 sequences of DENV E gene were acquired, including 68 DENV-1 sequences and 31 DENV-2 sequences. The cases of dengue fever were sporadic in 2018. Phylogenetic tree showed the strains isolated in 2018 were from multi-sources and closely related to those found in Guangzhou city and Southeast Asia area. Dengue fever outbreaks occurred in 2019 and most of the prevalent strains were from a single source, which was speculated to be Cambodia. Conclusions:Dengue fever in Shantou city was mainly caused by imported strains of the same year rather than by local strains in previous years. DENV strains in Shantou might be traced back to Southeast Asia area and transmitted to Shantou through many routes.

OBJECTIVETo explore the relationship between angiotensinogen (AGT) gene M235T and TCM syndrome type in essential hypertension (ET) patients.

METHODSThe gene mutation frequency of AGT M235T in 168 ET patients and 42 nomotensive (NT) subjects were determined using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) technique.

RESULTSThere was a significant difference in AGT M235T gene mutation between patients of Gan-fire exuberant type and those of yin-yang deficiency type (P < 0.01), homozygote type TT appeared with higher frequency. Multivariate regression linear analysis demonstrated that the genotypes of AGT M235T was correlated with the prognosis of ET to a certain degree.

CONCLUSIONGene mutation of AGT M235T may be associated with the genesis and development of ET, and the TCM syndrome type of ET has its own intrinsic molecular biological background.

Objective To study the pathological characteristics of interleukin-16 (IL-16) and CXC chemokine receptor 3 (CXCR3) in pulmonary artery of smokers with normal lung function and smokers with chronic obstructive pulmonary disease (COPD). Methods We examined surgical specimens from three groups of subjects undergoing lung resection for localized pulmonary lesions: group NS(nonsmokers with normal lung function, n=10); group S (smokers with normal lung function, n=13); group COPD (smokers with stable COPD, n=10). The clinical datas including blood gas analysis, pulmonary function,BMI, smoking index, BODE index, six-minute-walk distance (6MWD), Medical Research Council dyspened scale (MRC), St. George Respiratory Questionnaire (SGRQ) were recorded in all subjects before the operation. We applied technique of hematoxylin-eosin staining to observe pathomorphological changes of the pulmonary arteries. The concentration of IL-16 in lung tissues were measured by ELISA. Muscularized arteries were examined with immunohistochemical methods to identify T-lymphocytes (CD_3), CD_4 T-lymphocytes, CD_8 T-lymphocytes, IL-16, CXCR3. The correlation of IL-16 and CXCR3 in muscnlarized arteries in smokers with stable COPD were analysed. Results (1) The group COPD showed the highest concentration of IL-16 in lung tissue (P <0. 01) . The concentration of IL-16 in group S was higher than group NS (P<0.05). (2) Both in group S and group COPD, the percentage of the muscularized arteries that contained CXCR3 and IL-16 were increased as compared with group NS (P < 0. 01). Moreover there were statistical significance have been observed between group COPD and group S(P < 0.01). (3) The intensity of IL-16 infiltrating the muscularized arteries in group COPD showed a positive correlation with CD_3~+ T-lymphocytes, CD_8~+ T-lymphocytes, CXCR3 (r=0.639,0. 803,0. 696; P < 0. 05 or P < 0. 01), smoking index, BODE index (r= 0.737,0. 704; P < 0. 05). There was inverse relationship between the content of IL-16 in the muscularized arteries in group COPD and forced expiratory volume in one second% predicted (FEV_1 % Pred) and 6MWD (r=-0.803,-0.787; P<0.01). We also found the intensity of CXCR3 infiltrating the muscularized arteries in group COPD showed a positive correlation with CD_3~+ T-lymphocytes,CD_8~+ T-lymphocytes(r=0.650,0.767; P<0.05), smoking index, BODE index (r=0.650,0.767; P< 0.05). There was inverse relationship between the content of CXCR3 in the muscularized arteries in group COPD and FEV_1 % Pred and 6MWD (r=-0.778,-0.774;P<0.01). Conclusions (1) Both in group S and group COPD, IL-16 and CXCR3 were mainly expressed in lymphocytes which were correlated with CD_8~+ T-lymphocytes infiltrating the muscularized arteries. There were some suggestion that IL-16 prohaly recruited CD_8~+ T-lymphocytes into muscularized arteries by enhancing the expression of CXCR3. (2) The intensity of IL-16 and CXCR3 were correlated with the index of clinical and pulmonary function that suggested pulmonary arterial inflammation might be one of the key factors associated with the progression of COPD, and inhibiting the pulmonary artery inflammation played an important role in prevention and cure of COPD.

ObjectiveTo study the expression changes of peripheral blood monocyte human leukocyte antigen DR (HLA-DR) in patients with severe craniocerebral injury,and investigate the correlation between HLA-DR expression and infection and prognosis.MethodsNinety patients with craniocerebral injury were selected as experimental group and were divided according to the Glasgow coma scale (GCS) score after hospitalization into experimental group 1 (GCS score 13-15 scores ),experimental group 2 (GCS score 9-12 scores) and experimental group 3 (GCS score 3-8 scores) with 30 patients each,which were moderate,medium,severe craniocerebral injury,respectively.Thirty healthy people were chosen at the same period as control group.The HLA-DR expression of experimental group was detected after 1,3,7 and 14 d of admission by flow cytometry,and the HLA-DR expression of control group was detected on the day they got physical examination.The rates of infection,cure,disability,vegetative state and mortality were counted after 30 d of admission.ResultsThe HLA-DR expressions in experimental group 1 and experimental group 2 after 1,3,7,14 d of admission were (28.11 ± 2.37),(26.45 ± 1.63),(27.75 ± 1.83),(27.15 ± 2.17) MCF and (29.34 ±2.07),(27.55 ± 1.63),(28.42 ± 1.94),(29.46 ±2.12) MCF,which had no statistical difference compared with that in control group [(29.18 ± 1.91 ) MCF](P＞ 0.05).The HLA-DR expressions in experimental group 1 and experimental group 2 after 1,3,7 d of admission and control group had statistical differences compared with those in experimental group 3 after 1,3,7 d of admission [(18.02 ± 1.78),(16.05 ± 1.97 ),(20.76 ± 1.65) MCF ] (P ＜ 0.05).The HLA-DR expressions in experimental group 1 and experimental group 2 after 14 d of admission and control group had no statistical significance compared with that in experimental group 3 after 14 d of admission [ (26.13 ± 2.15) MCF](P＞ 0.05).The infection rates of experimental group 1,experimental group 2 and experimental group 3 were 0,3.6％(1/28),82.8％(24/29),respectively,while the cure rates were 100.0％ (30/30),100.0％ (28/28),10.3％ (3/29),the disability rates were 0,0,41.4％ (12/29),the vegetative state rates were 0,0,20.7％ (6/29),and the mortality were 0,0,27.6％ (8/29).There was no statistical significance in the rates of infection,cure,disability,vegetative state and mortality between experimental group 1 and experimental group 2 (P＞ 0.05 ).While there was statistical differences in the rates of infection,cure,disability,vegetative state and mortality among experimental group 1,experimental group 2 and experimental group 3 (P ＜ 0.05).ConclusionsThe HLA-DR expression changes of patients with moderate and medium craniocerebral injury after 1,3,7,14 d of admission are not significant.The HLA-DR expression of patients with severe craniocerebral injury begins to decline from 1 d after injury,declines obviously at 3 d,increases from 7 d,returns to normal level at 14 d.The decline of HLA-DR expression in patients with severe craniocerebral injury is correlated with the infection,and predicts poor prognosis.

AIM: To determine whether the eukaryotic initiation factor-4E (eIF-4E) inhibition facilitates the degradation of heparanase mRNA and alters heparanase protein expression in human colon adenocarcinoma cell line, LS-174T. METHODS: A 20-mer antisense s-oligodeoxynucleotide (asODN) targeted against the translation start site of eIF-4E mRNA were introduced into LS-174T cells by lipid-mediated DNA-transfection. eIF-4E protein and mRNA levels were detected by Western blot and RT-PCR, respectively. The mRNA levels of heparanase were determined by Northern blot. The alterations of heparanase expression were confirmed by Western blot analysis. RESULTS: The 20-mer asODN against eIF-4E specifically and significantly inhibited eIF-4E protein expression. Following eIF-4E inhibition, a significant reduction of heparanase mRNA was observed on Northern blot, and at the same time, heparanase protein expression significantly decreased as well. CONCLUSIONS: The results indicate that the inhibition of eIF-4E strongly reduces the stability of heparanase mRNA in colon adenocarcinoma cell line, LS-174T and resultes in an apparent reduction in the expression of heparanase protein.
