RESUMO

Presently, the improvement of soil organic matter is the basis to ensure food security, but the accumulation and transformation characteristics of soil phosphorus (P) as affected by organic matter remain unclear. The accumulation, transformation, and migration characteristics of soil P in different soil layers of vegetable fields were researched under the application of organic materials. Six treatments were set up in the experiment:control (no fertilization), traditional fertilizer application by farmers, biochar, chicken manure, food waste, and straw application. Available phosphorus (Olsen-P), water-soluble phosphorus (CaCl2-P) content, soil phosphorus forms, soil organic matter (SOM), and pH were determined during the pepper harvest period. In the 0-5 cm and 5-10 cm soil layers, the available phosphorus content of traditional fertilization of farmers was higher, and the available phosphorus content of the four organic materials was in the order of straw > biochar > chicken manure > food waste. Compared to that with food waste, the straw and biochar treatments increased soil available phosphorus by 59.6%-67.3% and 29.1%-36.9%, respectively. The straw treatment could easily enhance the soil labile P pool, and soil labile P in the 0-5 cm soil layer increased by 47.3% and 35.1% compared with that under the chicken manure and food waste treatments, respectively. With the increase in soil depth, the proportion of available phosphorus in the chicken manure treatment decreased the least, and available phosphorus of the 20-30 cm soil layer accounted for 55.9% of the topsoil layer but only accounted for 16.0%-34.0% under treatment with the other three materials. Compared with that under the traditional fertilization of farmers, the pH significantly increased by 0.18-0.36 units after the application of organic fertilizer, and the pH of the chicken manure and food waste treatments was significantly higher than that of biochar and straw (P < 0.05). SOM content under the biochar treatment significantly increased by 7.7%-17.6% compared to that under the other three organic materials. Among the four organic materials, the straw treatment boosted the labile P pool the most, which was conducive to the rapid increase in plant-available P. Phosphorus was most likely to migrate downward under the chicken manure treatment. In the field management based on soil fertility enhancement, the application of biochar could not only improve soil pH and SOM but also avoid excessive accumulation of phosphorus in the surface layer, which decreases environmental risks.

RESUMO

The clinical value of Chinese patent medicine is the core direction of the development of the traditional Chinese medicine industry. The precise clinical positioning determines the way to prove the value of the drug, and is a key link to highlight the clinical value. This paper presented a case study of clinical positioning for Chinese patent medicine, namely Qizhi Tongluo capsules, and the key technical framework of precise clinical positioning of Chinese patent medicine, which was manifested as a comparison of prescription target spectral effect, discovery of core value of prescription, and confirmation of clinical positioning trial. The technical framework was designed to address a range of issues in the realm of precise clinical positioning. Before the clinical positioning trial, based on the multi-component, multi-target, and multi-phenotype data of prescription and clinical indication, the multi-omics network analysis technology was used to identify the core value of the traditional Chinese medicine varieties and predict the potential clinical advantages. Then, based on the predicted clinical advantages, reasonable efficacy indicators were selected, and the clinical efficacy was judged and verified by dynamic and flexible innovative clinical trials to improve the success rate of clinical positioning. This research paradigm integrates "omics technology" with "evidence-based" principles and follows the "precise evidence-based" concept. This research aims to provide a new strategy and method for the precise medication and positioning of Chinese patent medicine with traditional Chinese medicine characteristics after being put into the market and provide more technical thinking for traditional Chinese medicine to move towards precise medicine.

RESUMO

Phosphogypsum (PG) contains a lot of soluble phosphate (PO43--P) and fluorine ion (F-), which seriously has hindered the sustainable development of the phosphorous chemical industry. In this study, a new burning raw material (BRM) as an intermediate product in the cement production process was used for PO43--P and F- stabilize in PG. The stabilizing mechanism of PO43--P and F- were investigated by Fourier Transform infrared spectroscopy (FT-IR), X-ray diffractometer (XRD), Scanning Electron Microscopy (SEM), X-ray fluorescence (XRF) and X-ray spectroscopy system (XPS). The effect of PG and BRM weight ratio, solid-to-liquid ratio, reaction time, and reaction temperature on the concentrations of PO43--P and F- were studied. The results showed that the concentration of F- in the PG leaching solution was 8.65 mg/L and the stabilizing efficiency of PO43--P was 99.78%, as well as the pH of the PG leaching solution was 8.12 when the weight ratio of PG and BRM was 100:2, and the solid to liquid ratio was 4:1, reacting for 24 h at the temperature of 30 â„ƒ. PO43--P and F- were mostly solidified as Ca5(PO4)3F, CaPO3(OH), Ca5(PO4)3(OH), Ca2P2O7·2H2O, CaSO4PO3(OH)·4H2O, CaF2, and CaFPO3·2H2O. Leaching test results indicated that the concentrations of PO43--P, F- and heavy metals were less than the integrated wastewater discharge standard (GB8978-1996). This study provides a new harmless treatment method for PG.

RESUMO

The construction of the comprehensive evaluation index system of the famous classical formula preparations after the marketing has both theoretical and practical significance. In this study, literature related to the post-marketing comprehensive evaluation of traditional Chinese medicine(TCM) compound preparations was retrieved from China National Knowledge Infrastructure(CNKI), China Science and Technology Journal Database(VIP), Wanfang Data Knowledge Service Platform(WanFang) and SinoMed from January 1, 2000 to April 30, 2022. CiteSpace 6.1.R2, a scientometrics software, was used to visualize the keywords involved, and to analyze the dynamic evolution trend and research hotspots in this field. Then, the existing comprehensive post-marketing evaluation index system of TCM compound preparations was screened and extracted, and the research status was systematically analyzed by mathematical statistics. It was found that there were problems such as the generalized boundaries between assessment dimensions and assessment elements, the lack of data sources for individual evaluation indexes, unset weight of some index system and insufficient application degree. In addition, according to the characteristics of famous classical formulas, the authors discuss the importance of evidence evaluation based on combination of disease and syndrome, pharmacovigilance of famous classical formulas preparations, and whole-process quality control of famous classical formulas, and put forward the construction strategy of comprehensive post-marketing evaluation of the famous classical formula preparations, which is oriented by clinical value, centered on evidence evaluation, and guaranteed by the whole-process quality control.

RESUMO

In this study, ultra-performance liquid chromatography-quadrupole/time-of-flight mass spectrometry(UPLC-Q-TOF-MS) and gas chromatography-mass spectrometry(GC-MS) were combined with non-targeted metabonomic analysis based on multivariate statistics analysis, and the content of five indicative components in nardosinone was determined and compared by UPLC. The main chemical components of Nardostachyos Radix et Rhizoma with imitative wild cultivation and wild Nardostachyos Radix et Rhizoma were comprehensively analyzed. The results of multivariate statistical analysis based on liquid chromatography-mass spectrometry(LC-MS) and GC-MS were consistent. G1 and G2 of the imitative wild cultivation group and G8-G19 of the wild group were clustered into category 1, while G7 of the wild group and G3-G6 of the imitative wild cultivation group were clustered into category 2. After removing the outlier data of G1, G2, and G7, G3-G6 of the imitative wild cultivation group were clustered into one category, and G8-G19 of the wild group were clustered into the other category. Twenty-six chemical components were identified according to the positive and negative ion modes detected by LC-MS. The content of five indicative components(VIP>1.5) was determined using UPLC, revealing that chlorogenic acid, isochlorogenic acid A, isochlorogenic acid C, linarin, nardosinone, and total content in the imitative wild cultivation group were 1.85, 1.52, 1.26, 0.90, 2.93, and 2.56 times those in the wild group, respectively. OPLS-DA based on GC-MS obtained 10 diffe-rential peaks. Among them, the relative content of α-humulene and aristolene in the imitative wild cultivation group were extremely significantly(P<0.01) and significantly(P<0.05) higher than that in the wild group, while the relative content of 7 components such as 5,6-epoxy-3-hydroxy-7-megastigmen-9-one, γ-eudesmol, and juniper camphor and 12-isopropyl-1,5,9-trimethyl-4,8,13-cyclotetrade-catriene-1,3-diol was extremely significantly(P<0.01) and significantly(P<0.05) lower than that in the wild group, respectively. Therefore, the main chemical components of the imitative wild cultivation group and wild group were basically the same. However, the content of non-volatile components in the imitative wild cultivation group was higher than that in the wild group, and the content of some volatile components was opposite. This study provides scientific data for the comprehensive evaluation of the quality of Nardostachyos Radix et Rhizoma with imitative wild cultivation and wild Nardostachyos Radix et Rhizoma.

RESUMO

Huocao(a traditional Chinese herbal medicine) moxibustion is a characteristic technology in Yi medicine suitable for cold-dampness diseases. Huocao, as the moxibustion material, is confusedly used in clinical practice and little is known about its quality control. In this study, UPLC method was used to establish the chemical fingerprint of non-volatile components in Huocao, and the contents of eight phenolic acids such as chlorogenic acid were determined. Multivariate statistical analysis was performed to obtain the indicator components of Huocao for quality evaluation, and thus a comprehensive evaluation system for the quality of Huocao was built. The UPLC fingerprints of 49 batches of Huocao were established, and there were 20 common peaks, of which eight phenolic acids including neochlorogenic acid and chlorogenic acid were identified. Except for three batches of Huocao, the similarity of the other 46 batches was higher than 0.89, suggesting that the established fingerprint method could be used for quality control of the medicinal herb. The correlation coefficient between entropy weight score of the eight phenolic acids and comprehensive fingerprint score in Huocao was 0.875(P<0.01), which indicated that the eight phenolic acids could be used as indicator components for the quality evaluation of Huocao. Furthermore, in multivariate statistical analysis on the common peaks of fingerprint and the contents of the eight phenolic acids, chlorogenic acid, isochlorogenic acid A and isochlorogenic acid C were screened to be the indicator components. The results revealed that the proposed method achieved a simple and accurate quality control of Huocao based on UPLC fingerprint and multi-component content determination, which provided useful data for establishing the quality standard of Huocao.

RESUMO

Gei Herba is a traditional folk herbal medicine with a variety of functions such as replenishing Qi and invigorating spleen, tonifying blood and nourishing Yin, moistening lung and resolving phlegm, activating blood and alleviating edema, moving Qi, and activating blood. The reports about the pharmacological effects of this herbal medicine have been increasing in recent years. By reviewing the ancient and modern literature about Gei Herba, we systematically organized the name, original plants, nature, taste, and functions of this herbal medicine, and summarized the modern pharmacological studies and clinical applications of Gei Herba in cardiovascular and cerebrovascular diseases. Gei Herba was first recorded in the name of "Dijiao" in the Geng Xin Yu Ce(《庚辛玉册》) written in the Ming Dynasty. It is derived from Geum japonicum var. chinense (Rosaceae) and sometimes confused with Adina rubella (Rubiaceae). This medicine had numerous synonyms in the local materia medica books. Gei Herba is widely distributed and harvested in summer and autumn, with the dried whole grass used as medicine. The historical records of the nature, taste, meridian tropism, main functions, and indications of Gei Herba are not consistent. It is generally believed that Gei Herba is pungent, bitter, sweet, cool, and has tropism to the liver, spleen, and lung meridians. Based on the effects of tonifying Qi, activating blood, and nourishing Yin, modern pharmacological studies have reported that the extracts of Gei Herba and the tannin phenolic acid compounds and triterpenoids isolated from Gei Herba have therapeutic effects on cardiovascular and cerebrovascular diseases such as hypertension, myocardial ischemia, cerebral ischemia, and vascular dementia. This study provides a reference for discovering the clinical advantages of Gei Herba and developing new drugs.

RESUMO

Existing traditional Chinese medicine (TCM)-related databases are still insufficient in data standardization, integrity and precision, and need to be updated urgently. Herein, an Encyclopedia of Traditional Chinese Medicine version 2.0 (ETCM v2.0, http://www.tcmip.cn/ETCM2/front/#/) was constructed as the latest curated database hosting 48,442 TCM formulas recorded by ancient Chinese medical books, 9872 Chinese patent drugs, 2079 Chinese medicinal materials and 38,298 ingredients. To facilitate the mechanistic research and new drug discovery, we improved the target identification method based on a two-dimensional ligand similarity search module, which provides the confirmed and/or potential targets of each ingredient, as well as their binding activities. Importantly, five TCM formulas/Chinese patent drugs/herbs/ingredients with the highest Jaccard similarity scores to the submitted drugs are offered in ETCM v2.0, which may be of significance to identify prescriptions/herbs/ingredients with similar clinical efficacy, to summarize the rules of prescription use, and to find alternative drugs for endangered Chinese medicinal materials. Moreover, ETCM v2.0 provides an enhanced JavaScript-based network visualization tool for creating, modifying and exploring multi-scale biological networks. ETCM v2.0 may be a major data warehouse for the quality marker identification of TCMs, the TCM-derived drug discovery and repurposing, and the pharmacological mechanism investigation of TCMs against various human diseases.

RESUMO

This article has systematically reviewed the name, origin, scientific name, producing area, quality evaluation, harvesting and processing methods of Polygonati Odorati Rhizoma(POR) by consulting the materia medica, medical books, prescription books and modern literature, in order to provide a reference for the development of famous classical formulas containing POR. Yuzhu was first recorded in the Shennong Bencaojing under the name of Nyuwei. After that, Weirui was used as the rectification name in the subsequent dynasties, and in recent times, the name of Yuzhu is mostly used in materia medica and prescription books. In ancient times, there were different names for Yuzhu, such as Nyuwei, Weiwei and Weirui. The names of the three are similar and there was a mixed use of the same name and foreign matter in history. In the Tang dynasty, SU Jing listed Nyuwei with the effect of curing dysentery in the intermediate of herbal part of Xinxiu Bencao according to its different efficacy. However, based on Shennong Bencaojing, Mingyi Bielu and the different energy efficiency of medical prescriptions, SU Song of the Northern Song dynasty believed that the three were medicinal materials of different origins. In short, the names of the three have been unclear in history for a long time. According to the development of the time line, this paper examines the names and realities of the three, and concludes that the two(Weiwei and Weirui) are the same medicinal material, that is, Polygonatum odoratum of Liliaceae, and the Nyuwei is Clematis apiifolia of Ranunculaceae, and the source relationship of the three is clarified. The mainstream source of Yuzhu used in the past dynasties was the rhizome of P. odoratum, which was widely distributed in the wild and has a large amount of resources. The origins of Yuzhu recorded in ancient times were mainly Taishan in Shandong, Chuzhou and Shuzhou in Anhui, and Hanzhong in Shaanxi, in modern times, it was produced in northern Hebei and Shaoyang in Hunan with high quality, and in the modern times, Jiangbei Yuzhu from Haimen in Jiangsu, Anyuzhu from Nanling, Anqing and Tongling in Anhui, Guanyuzhu from Fengrun, Yutian, Zunhua, Huailai in Hebei and Suizhong, Jinxi, Jianchang, Lingyuan, Liaoyang, Haicheng, Gaiping in Liaoning, Xiangyuzhu from Shaoyang in Hunan are the authentic medicinal material. In ancient times, the quality of Yuzhu was good if it was fat and white, while in modern times, it is better with thick roots, bright yellow color, soft texture, no stiff skin and no oiliness. In ancient times, the origin processing of POR was mostly dried in the shade, but in modern times, it is mostly sun-dried or dried after steaming and rubbing. The ancient processing was mostly scraped off the skin and soaked in honey water and then steamed through, while the modern one is mostly washed and cut into thick slices for raw use. Based on the conclusion of the herbal textual research, it is suggested that the rhizome of P. odoratum of Liliaceae be used as the source for the development of famous classical formulas, and the corresponding specifications be selected according to the processing requirements of the prescription. In view of the Yiweitang in Wenbing Tiaobian, which uses the method of frying fragrance to achieve the effect of fragrant refreshing the spleen, it can be processed by referring to the stir-frying method in the current version of Chinese Pharmacopoeia.
