The specific outcome Assessment Modal of acupuncture and Tuina treatment for pain / 国际中医中药杂志

Acupuncture and Tuina are the main non-drug therapies for low back pain, which are recommended by the guidelines. Acupuncture and Tuina can alleviate pain, which is regarded as conditional specific outcome, and improve mental, emotional problems, as non-conditional specific outcomes. There are some problems of the outcome assessment of acupuncture and Tuina treatment for pain such as insufficient evaluation of specific effect and unclear evaluation of characteristic outcome. Therefore, the key to above problems is to construct a Specific ouTcomE Assessment Modal of acupuncture and Tuina treatment for pain (STEAM-A&T) based on the qualitive and quantitative methods. By describing the experience, narrative expression, feelings and needs of patients who receiving acupuncture and Tuina treatment, the item banks of acupuncture and Tuina treatment effect are constructed, and the characteristic outcome of acupuncture and Tuina for pain will be screened, and then the relationship model among outcomes is constructed and optimized, which reflected the characteristics of acupuncture and Tuina for pain from multiple dimensions, multiple levels and multiple views. We reveal the relationship between the outcome of acupuncture and Tuina for pain. It will provide a new theory and methods for the construction of specific outcome assessment modal of Traditional Chinese Medicine.

[Quality-based soil fertility quality assessment of American ginseng main production areas in Shandong province].

The soil fertility quality is one of the most critical indicators of soil productivity. It directly affects the yield, quality and agricultural efficiency of Chinese medicinal materials. In order to establish the American ginseng planting soil fertility quality evaluation method based on the effective components of American ginseng, Wendeng district, Weihai city, Shandong province, the main producing area of American ginseng, was cited as a case for the study. Twenty-two 4-years American ginseng sampling sites are located at 7 towns. The samples of soil and plant root were collected in the autumn of 2017-2019. The saponin contents of American ginseng and 11 soil chemical properties were measured. The minimum data set(MDS) for assessment of the quality of soil fertility quality was established by correlation analysis and principal component analysis. The evaluation indexes were normalized by membership function. Soil quality index(SQI) that indicates soil comprehensive fertility quality level was calculated according to the critical value of membership function and weight value of each soil index in MDS. The results showed that the total saponin(Rg_1+Re+Rb_1) content of American ginseng in samples ranged from 1.76% to 7.94%. The yield of 8 plots in 2019 ranged from 3 818.7 kg·hm~(-2) to 8 996.4 kg·hm~(-2). MDS includes organic matter, alkaline nitrogen, exchangeable calcium, exchangeable magnesium, effective iron, effective copper, and effective zinc. Based on the mean of 4.825% of total saponin, threshold value of SQI for the region was determined to be 0.15, and 86.36% of soil samples in the county were above the threshold value. The methods and parameters are applicable to selection of high quality American ginseng planting sites and guiding rational fertilization. It also provides a reference for the evaluation of soil fertility quality of other medicinal plants.

To investigate the effect of acid and alkali stress on ginsenoside content of Panax ginseng, adventitious roots culture in bioreactors were incubated for 30 d and pH value was adjusted. Ginsenoside content increased by reducing or raising the pH in culture medium, the muxium ginsenoside content was determined on the 5th days after acid treatment and on the 7th days after alkali treatment. The result of histochemical localization of ginsenoside revealed that the red color from light to dark were found in the adventitious root tissue, and ginsenoside mainly located in the pericycle cells where appeared the dark red color.

Effects of several factors on cell growth and ginsenoside accumulation of Panax ginseng suspension culture / 中国中药杂志

To improve cell suspension culture system of Panax ginseng, the dynamic of cell growth and medium consumption were studied, and the effects of filter on the culture vessel, revolution number, and inoculation density on cell growth and ginsenoside accumulation were also investigated. The maximum cell growth and ginsenoside accumulation was found on the 20th days of suspension culture, therefore, 20 days were confirmed as a suitable culture period for mass production of ginsenoside. Cell growth and ginsenoside content were promoted when the culture vessel had a ventilated filter. Revolution speed during suspension culture affected cell growth, but not ginsenoside content, a peak of ginsenoside productivity was found in the treatment of 120 r x min(-1). Inoculation density also influenced cell growth and ginsenoside accumulation, inoculation density of 6 g was better than other inoculation densities, the ginsenoside content and productivity were up to 12.8 mg x g(-1) DW and 146.6 mg x L(-1), respectively.

Cultivation of protocorms of Dendrobium candidum in air-lift bioreactors / 中国中药杂志

<p><b>OBJECTIVE</b>To explore the factors affecting the growth of protocorms of Dendrobium candidum and substance synthesis in a reactor, in order to provide a new method for mass production of raw materials of D. candidum.</p><p><b>METHOD</b>Protocorms in vitro were used as experimental materials to study the effect of inoculum volume, light intensity and air volume on the growth of protocorms of D. candidum and the accumulation of polysaccharide and dendrobine in a 3 L-air lift balloon type bioreactor.</p><p><b>RESULT</b>After 30 days of cultivation in a bioreactor, protocorms became dark green and grew well at the inoculum volume of 10 g x L(-1). The polysaccharide content in protocorms showed no difference at various inoculum volumes; whereas the dendrobine content showed differences (with the highest treatment at the inoculum volume of 10 g x L(-1)), particularly the productions of polysaccharide and alkaloid reached the maximum at the inoculum volume of 10 g x L(-1). The condition of 1 600 lx of light intensity was the most favorable for the growth of protocorms. Though light played a role of improving the accumulation of polysaccharide in protocorms of D. candidum, it could inhibit the accumulation of dendrobine. Polysaccharide content and production were better under light conditions of 1 600 and 2 400 lx than dark conditions. Despite the maximum dendrobine content in dark conditions, the dendrobine production showed the maximum in the light condition of 1 600 lx due to poor growth of protocorms. Protocorms grew well and became dark green at the air volume of 0.2 vvm (air volume culture volume per minute) , which was better than at 0.1 and 0.3, with maximum polysaccharide and dendrobine contents and productions.</p><p><b>CONCLUSION</b>In a 3 L-air lift balloon type bioreactor with a working volume of 2 L, the conditions of 10 inoculum volume, 1 600 lx light intensity and 0.2 air volume were favorable for the growth of protocorms and the production of dendrobine. This demonstrates that the cultivation of D. candidum and substance synthesis in a reactor is an effectie approach for mass production of polysaccharide and dendrobine.</p>
