Objective To study the change of the structural and biological properties of the cardiovascular tissue after cell extracting. Methods The native and treated pulmonary cusp and pulmonary artery wall were evaluated by HE stain, ETVG stain, immunochemistry stain and scan electron microscopy. The contents of the main macro-molecules were measured. The content and position of calcium was investigated by subcutaneous implantation in a rat model. Results The acellularization procedure resulted in an almost complete removal of the original cells while the construction of the matrix remained. The contents of colleagen and elastin increased while soluble GAG reduced. The content of calcium in acellular tissue by xenogenic implantation was less obviously than that in fresh one. Conclusion A suitable acellularization procedure can remove all cells and most soluble proteins, and matrix remains nearly intact, so as to alleviate obviously calcification via xenogenic implantation in vivo.

Objective To investigate the effect on the differentiation of bone marrow mesenchymal stem cells (BMSC) with non-contact co-culture with mechanical stimulated ligament fibroblasts. Methods A cyclic 10% uniaxia strain at 1 Hz was applied on rat pelvic ligament fibroblasts, then were co-cultured with BMSC for 3, 6 and 12 days in non-contact condition. The protein expression of collagen Ⅰ ,Ⅲ in BMSC were detected by SP method and revealed by the mean gray value. The mRNA expressions of collagens type Ⅰ and type Ⅲ in the BMSCs were measured with real-time (RT)-PCR ,and the results were indicated by the ratio between the mRNA and glyceraldehyde-3-phosphate dehydrogenase (GAPDH) . Results (1) Protein expression; after 3 days co-culture with pelvic ligament fibroblasts, expression of collagen Ⅰ and Ⅲ in BMSC are 82. 4 ± 3. 4 and 76. 8 ± 2. 5. When compared with 80. 2 ± 2. 6 and 74. 6 ± 1. 1 in BMSC without co-culture, there was no significant difference (P > 0. 05) . After 6 days co-culture with pelvic ligament fibroblasts, the expression of collagen Ⅰ and Ⅲ of 126. 6 ±2. 2 and 118. 6 ± 1. 4 in BMSC were significantly higher than 82. 7 ±3. 0 and 76. 2 ± 1. 3 in BMSC without co-culture (P < 0. 05). Similarly, after 12 days co-culture with pelvic ligament fibroblasts, the expression of collagen Ⅰ and Ⅲ of 135. 3 ±3. 4 and 128. 7 ± 2. 6 in BMSC were significantly higher than 86. 6 ± 1. 3 and 81. 8 ± 1.4 in BMSC without co-culture (P <0.05). (2)mRNA expression:after 3 days co-culture with pelvic ligament fibroblasts , the mRNA expression of type Ⅰ and type Ⅲ collagens in BMSC are 2. 10 ±0. 20 and 1. 20 ±0. 30. When compared with mRNA expression of 2. 01 ±0. 12 and 1. 13 ±0.21 in BMSC without co-culture, no significant difference were observed (P > 0. 05). After 6 days co-culture with pelvic ligament fibroblasts , the mRNA expressions of type Ⅰ and type Ⅲ collagens mRNA were 5. 60 ±0. 21 and 2. 61 ±0. 20, which were significantly higher than 3. 70 ±0. 33 and 1. 82 ± 0. 14 in BMSC without coculture (P < 0. 05). After 12 days co-culture with pelvic ligament fibroblasts, the mRNA expressions of type Ⅰ and type Ⅲ collagens of 5. 91 ±0.31 and 2. 92 ±0. 23 were significantly higher than 4. 04 ±0. 21 and 2. 04 ±0. 13 in BMSC without co-culture (P <0. 05). Conclusion Non-contact co-culture with mechanical stretch stimulated ligament fibroblasts, it might promote synthesis of types Ⅰ and Ⅲ collagen in rat BMSCs and induced BMSC differentiated into pelvic ligament fibroblasts.

Objective To better promote the health education and health promotion among patients with chronic disease, general practitioners (GPs) in the community should master the knowledge of non-communicable diseases (NCDs). This paper aimed to describe the current situation of GPs' knowledge about prevention and treatment of NCDs. Methods Self-designed questionnaires were issued to 1 077 GPs in community health service centers, and all GPs finished the questionnaire without assistance. The content of questionnaire includes the general information of GPs and six questions focusing on NCDs. Results Overall, 1 076 GPs completed the questionnaire, and the response rate was 99.9% (1 076/1 077). With regard to the six questions about NCDs, 90.4% (973/1 076) of GPs were well aware of the diagnosis of hypertension. Apart from that, the knowledge of diabetes mellitus (60.9%, 655/1 076), factors related to NCDs (70.2%, 755/1 076), the concepts of mental illness (52.0%, 560/1 076) and the clinical significance of tumor markers (87.9%, 946/1 076) among GPs were adequate, while more than half of the GPs did not know a lot about home oxygen therapy. Conclusion The mastering level of knowledge about prevention and treatment of NCDs among GPs varies that they need further improvement.

Objective The aim of this study is to evaluate clinical application of BODE (body mass index, airflow obstruction, dyspnea, and exercise capacity) index in patients with chronic obstructive pulmonary disease (COPD). Methods Forty patients with stable COPD in Xuanwu Hospital of Beijing during September 2003 to December 2007, were recruited in the study, including 25 men and 15 women, aged 38 to 85 years (with a mean of 62 ± 13 years). BODE index was measured for each patient, one year and three years after recruitment, respectively. Severity of COPD, including number and duration of episodes, length of each hospital stay and times of hospitalization due to acute exacerbation of COPD (AECOPD), were recorded. All data were statistically analyzed with SPSS 13.0 software for windows. Results ①There was a remarkable difference in COPD severity between patients with BODE score equal to or greater than five and these with less than five (P <0.01 ). ①BODE score inversely correlated with forced expired volume at the first second ( FEV1 ) in COPD patients (P < 0.01 for those with BODE score equal to or greater than five and P <0.05 for these with BODE score less than five, respectively). ③BODE score positively correlated with number and duration of acute exacerbation, length of hospital stay and times of hospitalization due to AECOPD (P <0. 01 for those with BODE score equal to or greater than five and P < 0. 05 for those with BODE score less than five, respectively). For patients with COPD, their BODE score in the first year positively correlated with that in the third year ( r = 0.834, P < 0.01 ). Conclusions BODE index is a better indicator to evaluate their condition severity in patients with COPD.
