AIM： TO observe the effects of pre-moxibustion on apoptosis and proliferation of gastric mucosal cell in rats with stress-induced ulcer, and to analyze the relationship between those effects and the expression of heat-shock protein 70 （HSP70）. METHODS： Sixty healthy Sprague Dawley rats were randomly assigned into four groups, namely group A, B, C and D. The animal model of stress ulcer was established by water immersion and restraint stress. The rats in group A, B, and D served as the restraint, model, and non-acupoint controls, respectively, while those in group C received moxibustion at Zusanli and Uangmen points. Immunohistochemical methodology was used to detect the expression of HSP70, apoptosis index （AI, × 10^-6/μm^2） and proliferation index （PCna-LI, × 10^-6/μm^2）. The mucosal expression of transforming growth factor α （TGF-α） was detected by radioimmunoassay. RESULTS： IVloxibustion at Zusanli and Liangmen points significantly decreased the gastric injury and the apoptosis of gastric mucosal cells, while markedly increased the mucosal expression of TGF-α and HSP70 as well as the proliferation of gastric mucosal cells. Compared with group A, ulcer index （UI）（26.8 ± 9.8 vs 12.0 ± 5.9, P 〈 0.01）, AI （9.6 ± 4.2 vs 4.4 ± 2.6, P 〈 0.05） and expression of HSP70 （9.6 ± 4.2 vs 4.4 ± 2.6, P 〈 0.05） were significantly increased, but the content of TGF-α （104.7 ± 51.2 pg/mL vs 254.0 ± 86.9 pg/mL, P 〈 0.01） and PCna-LI （6.9 ± 4.7 vs 14.9 ± 4.6, P 〈 0.05） were significantly decreased in group B. However, ulcer index values （UI） and AI were obviously lower in group C compared to groups B and D （14.1 ± 5.4 vs 26.8 ± 9.8 and 26.2 ± 7.7, P 〈 0.01, 3.0 ± 1.6 vs 9.6 ± 4.2 and 8.2 ± 5.2, P 〈0.05, respectively）, but content of TGF-α （237.0 ± 72.6 pg/mL vs 104.7 ± 51.2 pg/mL and 154.1 ± 61.3 pg/mL, P 〈0.01） and expression of HSP70 （0.13 ± 0.03 vs 0.08 ± 0.06 and 0.06 ± 0.04, P 〈 0.05） were higher in group C. Furthermore, the PCna-LI was significantly higher in group C than in

Poultry Manure Compost Alleviates the Phytotoxicity of Soil Cadmium: Influence on Growth of Pakchoi (Brassica chinensis L.)

引用

Pedosphere 2010年第1期20卷 63-70页

作者： CHEN Han-Song HUANG Qiao-Yun LIU Li-na CAI peng LIANG Wei LI Ming Key Laboratory of Subtropical Agriculture and Environment of Ministry of Agriculture Huazhong Agricultural University Wuhan 430070 (China) State Key Laboratory of Agricultural Microbiology Huazhong Agricultural University Wuhan 430070 (China)

The growth performance of pakchoi （Brassica chinensis L.） in relation to soil cadmium （Cd） fractionations was investigated to evaluate the remediating effect of poultry manure compost on Cd-contaminated soil. A yellow-brown soil （Alfisol） treated with various levels of Cd （0 50 mg Cd kg^-1 soil） was amended with increasing amounts of compost from 0 to 120 g kg^-1. Compost application transformed 47.8%-69.8% of soluble/exchangeable Cd to the organic-bound fraction, and consequently decreased Cd uptake of pakchoi by 56.2%-62.5% as compared with unamended soil. Alleviation of Cd bioavailability by compost was attributed primarily to the increase of soil pH and complexation of Cd by organic matter including dissolved organic matter. In general, the improvement of pakchoi performance was more pronounced in higher Cd-contaminated soil. Addition of large amount of compost also favored the anti-oxidative capability of pakchoi against Cd toxicity. This low cost remediation method seems to be very effective in the restoration of Cd-eontaminated soils.

Understanding Qi Running in the Meridians as Interstitial Fluid Flowing via Interstitial Space of Low Hydraulic Resistance

引用

Chinese Journal of Integrative Medicine 2018年第4期24卷 304-307页

Qi, blood and the meridians are fundamental concepts in Chinese medicine（CM）, which are components of the human body and maintain physiological function. Pathological changes of qi, blood and meridians may lead to discomfort and disease. Treatment with acupuncture or herbal medicine aims to regulate qi and blood so as to recover normal function of the meridians. This paper explores the nature of qi as well as compares and correlates them with the structures of the human body. We propose a conceptualization of qi as being similar to the interstitial fluid, and the meridians as being similar to interstitial space of low hydraulic resistance in the body. Hence, qi running in the meridians can be understood as interstitial fluid flowing via interstitial space of low hydraulic resistance.
