Research on the Relationship between New Risk Factors and Traditional Risk Factors and Its Interaction with Natural Disasters： A Case Study between Population Urbanization and Natural Disasters in County-Level Administrative Units in China

Traditional risk factors fall into four categories： natural disasters, public health, accidents during production and social security. The four types of risks are called as public safety issues by the government of China. New risk factors are the ones that are connected to human discoveries and more attention to them, which is called locking risk. What is more, such risk factors will continue to emerge with the development of human society. Currently, traditional risk factors have not been eliminated, while new risks have emerged gradually. There are countless relations between new risks and global climatic changes. Therefore, figuring out the relationship between new risks, global climatic changes as well as natural disasters is of great importance. This study takes China as an example. The population data at county level in China in 1991, 2000 and 2009 （including rural population, urban population and total population of three） were selected. By calculating the urbanization rate of the population, the rate of urbanization at county level in China in three years was drawn. And it is superimposed with the disaster zoning in China to analyze the correlation between population changes and natural disasters and reveal the magnitude of disaster effects caused by population urbanization. It can provide the basis for the disaster chain risk assessment under the gnidanee of the regional law of China＇s natural disaster chain and lay the foundation for the study of the relationship between new risk factors and traditional risk factors. So, risks governance can be perfectly combined with developing the green economy during the development of human society, and ultimately, the goal of harmony between human and nature can be achieved.

Panax notoginseng saponins improve recovery after spinal cord transection by upregulating neurotrophic factors

Saponins extracted from Panax notoginseng are neuroprotective, but the mechanisms underlying this effect remain unclear. In the present study, we established a rat model of thoracic（T10） spinal cord transection, and injected Panax notoginseng saponins（100 mg/kg） or saline 30 minutes after injury. Locomotor functions were assessed using the Basso, Beattie, and Bresnahan（BBB） scale from 1 to 30 days after injury, and immunohistochemistry was carried out in the ventral horn of the spinal cord at 1 and 7 days to determine expression of nerve growth factor（NGF） and brain-derived neurotrophic factor（BDNF）. Our results show that at 7–30 days post injury, the BBB score was higher in rats treated with Panax notoginseng saponins than in those that received saline. Furthermore, at 7 days, more NGF- and BDNF-immunoreactive neurons were observed in the ventral horn of the spinal cord of rats that had received Panax notoginseng saponins than in those that received saline. These results indicate that Panax notoginseng saponins caused an upregulation of NGF and BDNF in rats with spinal cord transection, and improved hindlimb motor function.

A traditional Chinese herbal medicine compound preparation versus interventional therapy after resection of small hepatocellular carcinoma:22-year follow-up

OBJECTIVE:To compare the long-term effectiveness of compound Ruanjianhugan(RJH)tablets and interventional therapy(IT) in patients after resection of small hepatocellular carcinoma(HCC).METHODS:A retrospective study was conducted in 399 patients after resection of small HCC who were admitted between January 1987 and December 2008 in the Department of Hepatobiliary Surgery and Center of Minimlly Invasive Surgery,First Affiliated Hospital of Guangxi Medical University.Four groups were based on different therapy modes:a TCM-only(TCMO) group,a TCM combined with interventional therapy(TCM-IT) group,an interventional therapy-only(ITO) group,and a simple operation(SO) group.Prognostic factors were correlated with overall survival(OS) and OS rates were calculated with the Kaplan-Meier method,and multivariate analyses for factors affecting survival were evaluated by the Cox proportional hazard model.RESULTS:The median OS was 151.20 months in the TCM-IT group,43.87 months in the ITO group,and 20.77 months in the SO group.All survival rates of the TCMO group were higher than those of the other three groups(>50%).The 5-,10-,and 15-year OS in the TCMO and ITO patients were 83.94%,45.50%,and 71.22% and 33.34%,55.58%,and 9.26%,respectively(risk ratio,0.209;95% confidence interval,0.126-0.347;P=0.000).Multivariate analysis revealed that the independent risk factors were therapy mode(P=0.000),sex(P=0.005),family history(P=0.011),TNM Classification of Malignant Tumor staging(P=0.000),medical care-seeking behavior(P=0.021),and maximum diameter(P=0.030).CONCLUSION:Long-term oral use of compound RJH tablets may improve OS for small HCC after resection compared with IT.

An Exploration of Reasons for Shanghai’s Success in the OECD Program for International Student Assessment(PISA)2009

The outstanding performance of Shanghai students in the 4th Programme for International Student Assessment(PISA 2009)gained widespread attention at home and abroad.In this paper,the authors attribute this outstanding performance to three traditional factors and six modern factors.The traditional factors are high parental expectations,belief in the power of effort,and the mechanisms of personnel selection.The modern factors are the openness of Chinese education,curriculum and teaching reform,teacher training,improvement of comparatively poor schools,the financial resources allocation mechanism in compulsory education,and the reform of high school enrollment.

Mortality and recurrence of vascular disease among stroke patients treated with combined TCM therapy

OBJECTIVE:To confirm the long-term outcomes of stroke patients and determine predicting factors for death,recurrence of vascular events and poor outcome(either recurrence or death) after the use of combined TCM therapy.METHODS:This was a retrospective hospital-based cohort study and was performed in the First Affiliated Hospital of Tianjin University of Traditional Chinese Medicine in Tianjin.All subjects with stroke consecutively admitted to an inpatient ward of the Acupuncture Department from January 1,2008,to December 31,2008 were retrospectively followed through one year.The main outcomes were either a recurrence of vascular events,,mortality or both.Risk factors were recorded from medical records.Multivariate regression models were used to analyze predictors.The following independent variables were used:age,gender,hypertension,ischemic heart disease,atrial fibrillation,diabetes mellitus,carotid arterial lesions and history of stroke.RESULTS:Four-hundred and five patients were included.The 1-year mortality rate was 11.11%.23.70% of the patients had a recurrent vascular event,and 30.86% suffered a poor outcome.Multiple logistic regression analysis found that previous stroke,and advanced age were predictors of death within one year,Recurrence of vascular events was associated with carotid arterial lesions,history of diabetes and previous stroke.Long-term poor outcome was predicted by advanced age,history of diabetes,and previous stroke.CONCLUSION:Age,previous stroke,carotid arterial lesions and diabetes history seem to have different impacts on the three outcomes within one year.Our findings provide important data for planning future hospital register studies of stroke patients in TCM hospitals.

Effects of Shenlian Extracts (参莲提取物) on Atherosclerosis by Inhibition of the Inflammatory Response

Objective: Inflammation plays a critical role in atherosclerosis, and this inflammatory reaction is being intensively studied. Shenlian Extracts (参莲提取物), an active ingredient of Chinese medicinal herbs, is believed to have multiple therapeutic and preventive effects against human vascular diseases, including atherosclerosis. Our work investigated whether Shenlian Extracts serves as an anti-inflammatory agent during atherogenesis. Methods: We established a model of atherosclerosis in rabbits using balloon angioplasty and a high cholesterol diet. The effects of Shenlian Extracts on vessel structure and inflammation were assessed by hematoxylin-eosin staining of the femoral artery, measurement of inflammation-related factors in serum or vascular tissue, and radioimmunoassay. Enzyme linked immunosorbent assays (ELISA), flow cytometry and western blots were also performed. Results: We show that oral pre-treatment with Shenlian Extracts suppressed the pathological changes associated with atherosclerosis and that graded doses of Shenlian Extracts reduced total serum levels of cholesterol (90, 180 and 360 mg/kg), triglyceride (180 and 360 mg/kg), and LDL-c (90, 180 mg/kg). Various doses of Shenlian Extracts reduced serum content of TNF-α (180 and 360 mg/kg), CRP (90, 180 and 360 mg/kg) and IL-8 (360 mg/kg) (P<0.05), but led to no significant changes in IL-1β levels. Treatment with Shenlian Extracts also significantly reduced VCAM-1 levels (90 and 360 mg/kg) and IGF-1 levels (90 and 180 mg/kg) in vascular tissue but had no significant effect on ICAM-1 and MCP-1 levels. Finally, Shenlian Extracts significantly reduced the abnormal expression of CD18 in monocytes in a dose-dependent manner. Conclusion: These results suggest that Shenlian Extracts may play a direct role in preventing and treating atherogenesis by inhibiting the inflammatory reaction, providing insights into the possible mechanism underlying the anti-atherosclerotic actions of Shenlian Extracts.
