Objective To construct the fibroblast-specific non-viral vector pcDNA3-CEP-BMP-2 containing collagen 1A2 enhancer and promoter,and to validate the enhancement of BMP-2 expression in the human dermal fibroblasts by this vector,compared with the routine non-viral BMP2 vector. Methods The sequences for collagen 1A2 enhancer and promotor,and BMP-2 gene were ligated into the pcDNA3 plasmids.The plasmids were transfected into human skin fibroblasts and vein endothelial cells by means of cationic liposomes.The expressions of the plasmids in these two kinds of cells were detected by RT-PCR.The osteogenic phonotypes of fibroblasts were determined.(Results)pcDNA3-CEP-BMP-2,which contained collagen 1A2 enhancer and promoter could enhance the BMP-2 expression in the fibroblasts but not in vein endothelial cells.Osteogenetic phenotypes were more obvious in the fibroblasts transfected with pcDNA3-CEP-BMP-2 than in pcDNA3-BMP-2-transfected ones. Conclusion Collagen 1A2 enhancer and promoter can enhance BMP2 expression in fibroblasts.

Objective To identify the prevalence of different amyloid types in renal biopsies.Methods The renal biopsies of 205 patients diagnosed as renal amyloidosis from January 1990 to December 2011 were reassessed.Immunohistochemistry was performed with a penal of antibodies directed against λ-light chain,κ-light chain,amyloid A,fibrinogen,transthyretin,apolipoprotein A1,and lysozyme.Immune electron microscopy and gene analysis were performed when the results of immunohistochemistry were indeterminate.Results Among 205 patients,190 cases (92.7％) were classified as immunoglobulin light chain amyloidosis (AL),1 (0.5％) case as amyloid A amyloidosis and 1 (0.5％) case as fibrinogen A α-chain amyloidosis.The amyloid types of remaining 13 (6.3％) cases were undetermined.In the AL patients,the distribution of λ and κ was 6.6∶1.Conclusion AL is the most common form of renal amyloidosis in China,with a predominant light chain type of λ.

OBJECTIVETo study a feasible method of measuring right ventricular pressure by catheterization in mice.

METHODSMeasuring the right ventricular pressure and the pulmonary artery pressure by homemade PE pipe through venous cannula in external jugular vein, using catheterization in mice with powerlab multimodal biometric signal recording system.

RESULTSForty-six out of 51 mice were experimented with this method smoothly and got a total success rate of 90.2%. Thirty of 33 normal mice and 16 of 18 mice with pulmonary arterial hypertension (PAH) were catheterized successfully. The right ventricular pressure were as follow: systolic blood pressure: (23.4 +/- 5.7) mmHg in normal group vs (32.2 +/- 2.8) mmHg in mice with PAH, diastolic blood pressure: (3.7 +/- 2.6) mmHg vs (3.8 +/- 2.0) mmHg, mean pressure: (12.0 +/- 3.7) mmHg vs (14.9 +/- 2.3) mmHg. After autopsy for those 5 failed cases, we found that 2 cases were into the inferior vena cava, another 2 cases pierced the right auricle and the last one punctured the axillary vein into the chest wall.

CONCLUSIONMeasuring the right ventricular pressure through venous cannula in external jugular vein with homemade PE pipe in mice gets not only a high success rate but also help to save time. Moreover, this method can be popularized easily. It is a good and feasible method for measuring right ventricular pressure in mice.

0.05).Conclusions ATP-TCA could be used to individualize chemotherapy by selecting agents for particular patients of cervical cancer.The expression of GST-? and TS protein might be useful biomarkers to predict the resistance to DDP and 5-FU in patients with cervical cancer.

Background and purpose: The incidence and mortality of lung cancer ranked first in China. This study aimed to describe lung cancer survival in Shanghai, and provide background information for cancer prevention and treatment evaluation. Methods: Data of lung cancer cases diagnosed during 2002-2006, follow-up information and death report were collected from Shanghai Cancer Registry. Life table method and Ederer Ⅱ were used to calculate observed survival (OS) and relative survival (RS) respectively. Related demographic characteristics and status were also analyzed to present the survival situations of the lung cancer survivors in Shanghai. Results: In this study, 41802 lung cancer cases were included in analysis. The 5-year OS and RS for lung cancer were 13.75% and 20.23% respectively, and median survival time was 318 days. Survival rate was higher among females than males, with the 5-year OS of 15.49% and 13.00% respectively. The 5-year OS was higher among suburban residents (14.25%) than urban residents (13.23%). Survival rates decreased with increasing age and advanced stage. Patients aged 0-34 had a 5-year OS of 38.21%, while patients aged above 75 had a 5-year OS of 5.48%. Patients diagnosed with stage Ⅰ had a 5-year OS of 55.47%, while patients diagnosed with stage Ⅳ had a 5-year OS of 5.27%. Survival of lung cancer patients differed by tumor histological subtype. The 5-year OS of squamous lung cancer (24.40%) was higher than other histological types, followed by adenocarcinoma (22.26%), large cell (20.27%) and small cell lung cancer (12.22%). From 1972-1976 to 2002-2006, the 5-year OS of urban male patients increased from 6.8% to 12.4%, and 5-year OS of urban female patients increased from 7.3% to 14.9%. Analysis of RS gave the similar results. Conclusion: During the past 30 years, survival rate of lung cancer patients in Shanghai improved steadily, and the survival condition is above average among different countries and areas. However, survival rate of lung cancer is still low compared with other types of cancer. Future focus should be placed on the control of tobacco smoking, early detection by low-dose helical computed tomography and targeted therapy to further improve lung cancer survival.

Objective To investigate effects of combining Traditional Chinese Medicine (TCM) diet with lifestyle interference including disease related knowledge education, movement guidance, diet management and lose weight guidance on the patients with impaired glucose regulation (IGR). Methods A total of 200cases of community IGR patients were divided into three groups randomly:67 cases in blank group , 67 cases in comparison group and 66 cases in study group. The comparison group was performed lifestyle guidance while the study group was conducted TCM diet combination with lifestyle interference. Clinical outcomes containing FBG,2h PG and BMI were compared at 18 month later among three groups. Results After 18 months, in the three groups(blank groups, the comparison group and the study group)5.97%, 29.85% and 59.09% patients reverted to normal glucose tolerance, 79.10%, 64. 18% and 37.88% patients remained IGR and 14.93%,5.97% and 3.03% patients progressed into the diabetes mellitus. FBG, 2h PG and BMI were significantly different when the comparison group compared with the study group and the blank group compared with the study group or the comparison group. Conclusions Combining TCM diet with lifestyle interference can lower the FBG and 2h PG and improve the clinical outcome for patients with IGR.

Mongolian folk medicine, the important part of Mongolian medicine, is the main means, method and weapon of disease prevention, treatment and health care. Mongolian materia medicas are the important literatures of guiding the healthy development of the modern Mongolian medicine with a long and dazzling history. Since the founding of new China, a new history chapter of Mongolian folk medicine was opened under the attention and support from all levels of party and government. This paper intends to provide comprehensive insight into the rapid development of Mongolian folk medicine. The resources, phytochemistry, quality standard, pharmacology, dosage forms reform and production were reviewed to expound the process that Mongolian folk medicine was developed from traditional practices to scientific development

Objective To study mental characteristics of children with light lead poisoning. Methods Eighty - six children with light lead poisioning and 33 control children were evaluated with WISC - R and social adaptive capacity(SAB). Results 1. Intelligence quotient( IQ)and SAB of children with light lead poisoning were lower than normal children. 2. There was also deficiency of perception factor and memory/ concentration factor among children with lead poisioning and the blood lead level had negative association with perception factor. Conclusion Light lead poisioning may affect children's IQ, especially in the perception factor and memory /concentration factor.
