ABSTRACT
ObjectiveTo explore the effects of three kinds of microbial fertilizers on the growth， yield， quality， and cadmium （Cd） accumulation of Chuanxiong Rhizoma （CX）. MethodTaking CX seeds as materials， field experiments were carried out in the main producing areas， Pengzhou and Meishan. The samples were collected during the harvesting period， and the agronomic characters and yield were determined. The contents of extract， volatile oil， and ferulic acid were analyzed by the collection method of Chinese Pharmacopoeia （2020 edition）. The content of Cd was determined by inductively coupled plasma-mass spectrometry （ICP-MS）. Data were processed by difference significance analysis， correlation analysis and cluster analysis. ResultThree kinds of microbial fertilizers with appropriate concentrations could promote the growth of CX. In terms of yield and quality， the treatment of Jinwuzong （1.50 ton/hm2， 1 ton=1 000 kg， the same below） and Cuijingyuan （1.5 L·hm-2） could increase the yield of medicinal materials by 0.92%-46.34%， while Cuijingyuan （1.8 L·hm-2） and Shenchu （15， 30 kg·hm-2） could increase the water-soluble extract of CX by 0.06%-18.79%， of which Cuijingyuan （1.8 L·hm-2） was significantly increased （P<0.01）. The alcohol-soluble extract of CX treated with Jinwuzong （0.75， 1.50， 2.25 ton/hm2）， Shenchu （15， 45 kg·hm-2）， and Cuijingyuan （1.2 L·hm-2） decreased significantly by 3.51%-22.94% （P<0.01）. The content of ferulic acid in CX treated with Jinwuzong （1.50 ton/hm2） and Shenchu （30 kg·hm-2） decreased by 2.14%-30.56%. Three kinds of microbial fertilizers had little effect on the content of volatile oil in CX. In the aspect of Cd enrichment， the concentration of Cd in rhizosphere soil of CX was increased by 11.33%-76.36% （P<0.01） after the treatment of Jinwuzong （0.75， 1.50， 2.25 ton/hm2）， Shenchu （15， 30， 45 kg·hm-2） and Cuijingyuan （1.2 L·hm-2）. However， the Cd enrichment coefficient of CX reduced by 2.58%-48.38%， the Cd content and Cd accumulation of CX decreased respectively by 9.54%-25.96% and 9.34%-18.88% via Jinwuzong （0.75 ton/hm2） and Cuijingyuan （1.8 L·hm-2）. ConclusionThree kinds of microbial fertilizers have a certain positive effect on the growth， substance accumulation， and reduction of Cd content in medicinal parts of CX， and the changes of each index are affected by the producing area and treatment method. Based on the comprehensive analysis of various indicators， Jinwuzong （0.75， 1.50 ton/hm2） can better adapt to the rhizosphere soil micro-ecological environment of CX， it can effectively reduce the content of Cd on the premise of guaranteeing the yield and quality of CX.
ABSTRACT
Alzheimer' s disease (AD) is a chronic neurodegenerative disease, which is seriously affecting people' s lives. Until now, the pathogenesis of AD is still unknown which result in its worldwide difficulties in prevention and treatment. Some studies have shown that AD might be a metabolic disease associated with glucose, lipid and energy metabolisms. Traditional Chinese medicine (TCM) believes that the spleen is acquired foundation and the origination of Qi and blood. The function of spleen is not only closely related to the metabolism of substance and energy, but also related to the aging of human body. In this article, we summarized and analyzed the interrelationship of metabolism, AD and spleen, as well as the effect of spleen-invigorating prescription on AD. The purpose of the paper is to analyze the possible mechanism of TCM treating AD from the perspective of regulating metabolism, explore the potential value of spleen-strengthening TCM in the treatment or prevention of AD, and provide new ideas for exploring the drug development and TCM therapy of AD.
ABSTRACT
The medicinal science has been plagued by drug resistance of bacteria and antibiotic medicine with side effect for years. The problem could not be solved only by the chemistry medicine treatment. For thousand years, Traditional Chinese medicine (TCM) had made a significant contribution to people's health and has played an important role in preventing and controlling bacterial infection in the near centuries. As wide sources, less side effect, and less resistant to bacterial, TCM drew a great attention in anti-infection recently. Following the literature and clinic trial reports in the lastest 15 years, we summarized the studies on the bacteria-resistance and therapy of traditional Chinese and Western medicines, and analysed the researches on the antibacterial effects of compound TCM, single Chinese herbs, and chemical components from herbs. The results will provide the new ideas on the application and development of TCM with anti-infection.
ABSTRACT
<p><b>OBJECTIVE</b>To observe the prevalence and drug tolerance of mycoplasma(Ureaplasma urealyticum and Mycoplasma hominis) in patients with urogenital inflammation.</p><p><b>METHODS</b>Three thousand and fifty-five patients with urogenital inflammation such as non-gonococcal urethritis(NGU), chronic prostatitis or pelvic inflammation from 1999 to 2003 were included. The results of mycoplasma culture and drug sensitivity test were analyzed.</p><p><b>RESULTS</b>A total of 992(32.5%) cases were mycoplasma positive in the 3,055 patients, and there was no significant difference in the yearly positive percentage in the 5 years (P < 0.05). Among them, 701(70.7%) were infected with Ureaplasma urealyticum, 44(4.4%) with Mycoplasma hominis, and 247(24.9%) with both Ureaplasma urealyticum and Mycoplasma hominis, the Ureaplasma urealyticum infection rate being much higher than that of Mycoplasma hominis and mixed infection (P < 0.01). The high colony counting(> or = 10(4) cfu/ml) in Ureaplasma urealyticum infection patients accounted for 76.7%, while Mycoplasma hominis infection represented only 18.2%. The results of drug tolerance test showed a higher sensitivity to doxycycline, pristinamycin, josamycin and tetracycline (94.3%, 96.6%, 86.5% and 97.4% respectively), and a lower sensitivity to erythromycin and ofloxacin (54.8% and 29.4% respectively).</p><p><b>CONCLUSIONS</b>Ureaplasma urealyticum and Mycoplasma hominis should be detected simultaneously and the drug tolerance test is needed for the selection of appropriate antibiotics.</p>
