Cardiac enlargement is an important symptom of vascular and heart disease. The cardiothoracic ratio (CTR) is an important index used to measure the size of heart. The aim of this study was to assess the relationship between aging and cardiothoracic ratio. This paper also presents an improved C-V level set method to segment lung tissue based on X-ray image, which used to automatically compute CTR. In the investigation carried out in our school, we got more than 3 120 chest radiographs from medical examination of the working population in Beijing, and we systematically studied the effects of age and gender on the CTR to obtain reference values for each group. The reference values established in this study can be useful for recording and quantifying the cardiac enlargement, so that it may be useful for calling attention to the cardiovascular diseases and the heart diseases.

By retrospective analysis method, the paper was summarized experience of clinical pharmacy of TCM. The purpose of the paper was given location of clinical pharmacists in Traditional Chinese Medicine(TCM), to clear their main status and functions, seek methods and ways to solve the problems in the process of work. The work was proceeding orderly. Good results have been achieved. The clinical pharmacists of TCM participate in clinical rational use of drugs to change the service mode ofindirect service for the patients in the past with the patients, doctors and nurses so as to make better service for people's life and health of Chinese medicine.

BACKGROUND:Behavioral problems among preschool children affect the quality of life in childhood, and it may predict psychiatric disorders in adulthood.OBJECTIVE:To investigate the correlation of behavioral problem occurrence with gender and breastfeeding in children aged 4-5 years old.DESIGN: A stratified random cluster sampling investigation.SETTING:Department of Child Health Care,Affiliated Hospital of Medical College of Qingdao University,and Department of Preventive Medicine, Medical College of Qingdao University.PARTICIPANTS:Totally 600 children (301 boys and 299 girls) aged4-5 years old from 10 kindergartens in 4 districts in Qingdao city were chosen by stratified random cluster sampling during May in 2004.They. all used to be full-term infants of natural labor.METHODS:Achenbach Child Behavior Checklist (CBCL) for parents and self-made inventory scale influencing children's behavior were adopted. Behavioral problems were dependent variables whereas feeding category and breastfeeding duration were independent variables. The effects of feeding category in the first 4 months of life and breastfeeding duration on children's behavior were examined by single factor and multiple factors logistic regression (backward selection).MAIN OUTCOME MEASURES:Breastfeeding condition, breastfeeding duration and behavioral development.RESULTS:According to intention-processing analysis, 600 children 14.2% (85/600) among the 600 children investigated. It was 17.94%(54/301) in males and 10.4% (31/299) in females,with a significant indicated that boys who had been fed on "more infant formula than problem occurrence (OR=2.72,4.29). Breastfeeding duration ≥9months was a protective factor for males (OR=0.43) Girls who feeding duration ＜ 1 month had a risk of behavioral problem ocfeeding duration were set as independent variables and with or without behavioral problems was set as dependent variable to perform multiand breastfeeding duration ≥ 9 months were the risk factors and protective factors of behavioral problem occurrence for males (OR=3.76,ioral problem occurrence for females (OR=2.55,7.79,7.79), which were tective factors of behavioral problem occurrence for males (OR=3.48,behavioral problem occurrence for females ( OR=2.49,9.81,12.89).CONCLUSION:Male is a risk factor of behavioral problems;less breastfeeding and shorter breastfeeding duration are the risk factors of behavioral problem occurrence in children aged 4 to 5 years.

Objective To explore the curative mechanism of Jieyuan (JY) Capsule on rats renal failure induced by 5/ 6 nephrectomy. Methods Chronic renal failure (CRF) rat models induced by 5/6 nephrectomy were administered with JY Capsule. The serum levels of blood urea nitrogen (BUN) and serum creatinine (Scr),hematological and biochemical indexes,and renal histological features were observed. Results JY Capsule reduced levels of BUN and Scr,ameliorated the electrolyte,increased the number of red blood cell and hemoglobin content,and alleviated pathological changes of the kidney tissue. Conclusion JY Capsule can relieve the rat CRF symptoms and postpone the progress of CRF.

Bone marrow mesenchymal stem cells (BMSCs) are a kind of pluripotent stem cells derived from bone marrows, which can not only support hematopoiesis, but also have capabilities of multidifferentiation, high-proliferation and self-renewing. They have become one of hotspots in stem cell studies. Studies on in vitro intervention with BMSCs with TCMs have made remarkable progress in recent years. According to the findings, some traditional Chinese medicines can promote proliferation of BMSCs, some can inhibit the apoptosis of BMSCs, while others can induce BMSCs to differentiate into multiple cell types, such as osteoblast. Furthermore, some studies also involved relevant action mechanisms. The authors summarized the advance in relevant studies by reference to relevant literatures of this field.
