ABSTRACT
Starting from the inheritance and development of Chinese philosophy of life and Traditional Chinese Medicine (TCM) wisdom through the Chinese narrative medicine practice, this paper discussed the inheritance and correspondence relationship between the text reading ability in Chinese narrative medicine practice and the "four diagnostic" in TCM wisdom, narrative regulation and the "mind-body philosophy" in TCM, as well as the narrative wisdom and the "Tao produces one" in the Chinese philosophy of life. By analyzing the stories of contemporary doctors’ practice of narrative wisdom, this paper clarified that the Chinese narrative medicine system is a new model of medical education and clinical practice constructed by absorbing the essence elements of Chinese traditional life wisdom and TCM culture, and integrating the concept of western narrative medicine. It advocated for Chinese scholars to actively build the discipline of "narrative traditional Chinese medicine", constantly translate and introduce the achievements to foreign countries, and create a good narrative ecology of TCM.
ABSTRACT
Objective@#To investigate the characteristics, temporal trend of silicosis, and provide basis for risk assessment and precise prevention and control of occupational diseases.@*Methods@#Using descriptive statistics to analyze the reported cases of silicosis by SPSS 20.0 software. Reported silicosis cases, the constituent ratio, the incidence age and the working age at onset were analyzed by a linear trend test. Analyzing the variation trends of regional, industry, economic type and enterprise scale distributions by the chi-square trend test. Moreover, using Moran's I method for spatial autocorrelation analysis and trend-surface analysis.@*Results@#(1) During 2006 to 2015, Guangdong province had reported 1, 428 cases of silicosis, mainly gathered in Foshan, Zhongshan, Guangzhou, Shenzhen, which included 1391 male cases accounting for 97.41%. And the average incidence age was 45 (39, 51) . The average working age of onset was 9 (5.5, 15) . In economic type distribution, the private economy took the main part, accounting for 59.1%. In enterprise scale distribution, it was dominated by small and medium enterprises (SMEs) , accounting for 32.4% and 37.3% respectively. In industry distribution, most cases were gathered in materials and mining industry, accounting for 32.1% and 22.9% respectively. (2) The number of silicosis cases, the incidence age and the working age of onset showed a rising trend (P<0.01) . Meanwhile, the constituent ratios of medium-sized enterprises and building materials industry were increasing (P<0.05) . The annual variation trends of regional, economic type and age distributions were not statistically significant (P> 0.05) . (3) The spatial distribution trend showed an inverted U type, which was firstly raised and then declined from south to north and from east to west. The distribution characteristic demonstrated some high-high cluster areas, including Chancheng, Nanhai, Shunde, Panyu, Dongguan, Pengjiang, and Zhongshan. While Wuhua showed a high-low outlier form (P<0.01) .@*Conclusion@#Silicosis cases, age and working age of onset were on the rise, as well as the industry and enterprise scale distributions of occupational diseases presented a certain trend in Guangdong province from 2006 to 2015. There were high-high cluster and high-low outlier phenomena in spatial distribution with spatial correlation. Therefore, our work of silicosis epidemic trend and distribution may provide some bases for the occupational disease risk assessment and control.
ABSTRACT
Objective To investigate the content of cadmium in shellfish in Guangdong Province and make dietary exposure assessment of cadmium in shellfish.Methods The shellfish samples were collected from Pearl River Delta,Eastern and Western Guangdong Province using random sampling method.Point assessment method was used to evaluate the exposure of dietary cadmium intake from shellfish.The risk of dietary cadmium exposure from shellfish were evaluated.Results Three hundred and seven samples were included in the analysis.The median concentration of cadmium in shellfish was 0.630 mg/kg and the exceeding standard rate was 23.8％ (73/307).The exceeding standard rates in Eastern Guangdong,Western Guangdong and Pearl River Delta were 19.4％ (13/67),23.5％ (16/68),and 25.6％ (44/172),respectively.The corresponding median concentration of cadmium were 0.530,0.806 and 0.853 mg/kg,and the difference was not statistically significant (x2 =0.94,P ＞ 0.05).The average (P50) and high level (P97.5) daily intake of cadmium from shellfish by the total survey population was 0.957 μg/d,and 4.511 μg/d,respectively.The monthly intake of cadmium associated with shellfish calculated from average and P97.5 exposure doses accounted for 1.91％ and 9.02％ of PTMI,respectively.Conclusion The cadmium content of some shellfish in Guangdong Province exceeded the standard.However,the cadmium intake from shellfish by the survey population was not high.
ABSTRACT
Objective To investigate the effect of Buyanghuanwu decoction(BYHWD) on the expression of growth-associated protein 43(GAP-43) and synaptophysin(SYP) after focal cerebral ischemia in mice.Methods Focal cerebral ischemia was induced by 30 min of middle cerebral artery occlusion followed by reperfusion.BYHWD (20 g/kg) was administered orally 24 h after ischemia and once a day.The neurological score and the corner test were used to evaluate sensorimotor function on 1,3,7,and 14 days after ischemia.The expression of GAP-43 and SYP in the ischemic boundary zone was determined by immunohistochemistry 14 days after ischemia.Results Compared with the model group,BYHWD significantly ameliorated neurological dysfunction at 3,7 and 14 days and reduced the number of right turn at 7 and 14 days after ischemia(P ＜ 0.05).The average optical density of GAP-43 and SYP was 0.217 ±0.012 and 0.278 ±0.019 at the boundary zone in model group 14 days after ischemia,respectively.BYHWD also significantly increased the immunoreactivity of GAP-43 (0.250 ± 0.013)and SYP(0.323 ± 0.017) (P＜ 0.01).Conclusion BYHWD promotes axonal regeneration and synaptic plasticity in the ischemic boundary zone,which may contribute to functional recovery after focal cerebral ischemia.
