ABSTRACT

"Taking drugs for a long term" is a qualitative expression of medication method based on the efficacy and safety of Chinese medicine, and the study on it is conducive to the full utilization of the efficacy and rational use of drugs. There are 148 drugs that can be taken for a long time recorded in Shen Nong's Classic of Materia Medica, accounting for 41% of the total drugs. This paper analyzed three-grade classification, natural qualities, four properties and five flavors, and efficacy features of the "long-term taking" drugs(LTTD), thus exploring the herbal source of traditional Chinese medicine health care and the rationality of effect accumulation by long-term taking. It was found that there were more than 110 top-grade LTTD in Shen Nong's Classic of Materia Medica, most of which were herbs, with sweet flavor, flat property, and no toxicity. The efficacies were mainly making body feel light and agile(Qingshen) and prolonging life. Eighty-three LTTD were included in the Chinese Pharmacopoeia(2020 edition). In the modern classification, tonic LTTD accounted for the most, followed by damp-draining diuretic LTTD and exterior-releasing LTTD. Twenty LTTD were included in the "List of Medicinal and Edible Products" and 21 were in the "List of Products Used for Health-care Food", involving in various modern health care effects, such as enhancing immunity, assisting in reducing blood lipids, and anti-oxidation. Shen Nong's Classic of Materia Medica is the classic source of traditional Chinese medicine health care, and its medication thought of taking drugs for a long term to accumulate effects has guiding significance for the regulation of sub-health and chronic diseases nowadays. The efficacy and safety of LTTD have been examined in practice for a long time, and some of the drugs are edible, which is unique in the whole cycle of health-care service, especially in line with the health-care needs in the aging society under the concept of Big Health. However, some records in the book are limited by the understanding of the times, which should be scientifically studied according to the Chinese Pharmacopoeia and the related regulations and technical requirements, under the attitude of eliminating falsifications and preserving the truth and keeping the right essence, so as to achieve further improvement, innovation, and development.

ABSTRACT

@#Objective:To study the molecular biology mechanisms of Wistar rats after spinal cord injury, and find out key microRNAs. Methods:A total of 15 Wistar rats were divided into control group (<italic>n</italic> = 3) and spinal cord injury group (<italic>n</italic> = 12). The latter group was divided into four hours, three days, seven days and 14 days subgroups, with three rats in each subgroup. Microarray 3.0 was used to investigate microRNA expression profiles of Wistar rats with spinal cord injury. Bioinformatics was used to predict microRNAs playing key regulatory roles, and to predict target genes. Reverse transcription real-time quantitative polymerase chain reaction (RT-qPCR) was applied to detect the expression of miR-20a-3p. Western blotting was employed to detect the signal transducer and activator of transcription (STAT) 3 level. The correlation between target protein and microRNA expression trend in each group was analyzed. The key microRNA was inhibited in the neurons. The relationship between target protein expression and axon growth was observed with immunofluorescence. Results:In the rats with spinal cord injury, totally 658 microRNAs had changed at least once. In all the altered microRNAs, miR-20a-3p was upregulated obviously. It predicted that the target gene of miR-20a-3p was STAT3 via application of bioinformatics analysis. The expression trend of STAT 3 and miR-20a-3p in spinal cord was opposite. After the inhibition of miR-20a-3p, the expression of STAT3 in neurons was unregulated and axonal growth was extended. Conclusion:The upregulation of miR-20a-3p leads to downregulation of STAT3, and miR-20a-3p is one of the key targets in the treatment of spinal cord injury.

ABSTRACT

The quality control of traditional Chinese medicine provides the premise of its modernization and globalization. Currently, the dual quality control based on chemical benchmark and effect benchmark has been recognized domestically and internationally. Research efforts have lead to establishment of a series of effective quality control methods based on chemical components, medicinal properties, microscopic characteristics, material constituents and pharmacodynamic targets. In the study of quality control based on chemical benchmarks, fruitful results on fingerprints, DNA barcodes, and quality markers have been achieved. However, due to a variety of factors, such as growth period, origin, growth environment and preparation process of traditional Chinese medicine, the quality control of traditional Chinese medicine based on chemical benchmarks remains difficult to fully reflect the quality of traditional Chinese medicine. At present, there is still a dispute on how to accurately reflect the quality of traditional Chinese medicines based on chemical benchmarks. For example, the index components selected in the Chinese medicine quality standards are difficult to totally reflect all the components of Chinese medicine, and the relevance between the index components versus therapeutic effect is not yet clear. In view of the complex signal network by cascade reaction and crosstalk of multi-signaling pathways within an organism, and the coordinated regulation of multi-components and multi-targets of traditional Chinese medicine, there may be different components regulating the same signal network or situations where the amount of certain chemical components within a range is not sufficient to cause a change in the signal network. Therefore, the quality control of traditional Chinese medicine based on the effect benchmark may be a useful supplement to the quality standard of traditional Chinese medicine. This paper proposes a Q-biomarker research strategy based on the effect benchmark in order to provide a methodological reference for the quality control research of traditional Chinese medicine.

ABSTRACT

The plants of Bletilla are one of the groups in Orchidaceae with the highest economic value. As the traditional Chinese medicinal material, Bletillae Rhizoma exhibits excellent efficacy in hemostatic, antibiosis, detumescent, anticancer activities and regenerating tissue to heal wound, which has great development potential. However, Bletillae Rhizoma is mainly collected from wild resources. At present, the quantity of wild resources of Bletilla plants has sharply decreased and is far from meeting the needs. Resource appraisal and breeding and cultivation of excellent germplasms of Bletilla plants are important for scientific utilization of the resources of the genus. This paper reviewed the following researches of Chinese Bletilla resources: species and distribution, genetic diversity, active ingredient evaluation, breeding, as well as seeding production and cultivation techniques. Suggestions were also provided in further researches on the resources evaluation, sustainable development and efficient utilization of Chinese Bletilla plants.

ABSTRACT

Cor pulmonale rat models were induced by a single intraperitoneal injection of monocrotaline(MCT), and the sham group received a single intraperitioneal injection of normal saline. After the model rats received intragastric administration of Qishen Yiqi droplet(QS) for 6 weeks, the contents of adenylate(ATP, ADP and AMP) in right myocardial tissues were measured by HPLC, and then the metabolism changes in myocardium of cor pulmonale rats with QS were investigated. The results showed that ATP, ADP, and AMP were well separated, with a good linearity within a certain range of concentration; and the recovery rates were within the range of 90%-108%. As compared with model group, the level of ATP was significantly elevated in high-dose treatment group; ADP contents showed an increasing trend and AMP contents showed a decreasing trend, indicating that QS could significantly improve energy metabolism system in myocardium. By using the HPLC, a qualitative and quantitative analysis method was given for the determination of ATP, ADP and AMP contents in myocardium, providing a method for energy metabolism measurement in biological samples.

ABSTRACT

To study the protective effect of Danqi Piantan capsule ( DPC) and its antelope horn substitution (DPCAS) on the cerebral ischemia, in order to preliminary study the possibility of replacing antelope horn with artificial bezoar. In this study, the left middle cerebral artery occlusion (MCAO) was adopted. Totally 150 SD rats were randomly divided into 5 groups: the sham operation group, the model group, the Danqi Piantan capsule (DPC) group (0.246 g x kg(-1) x d(-1)), the Danqi Piantan capsule without antelope horn (DPCRA) group (0.246 g x kg(-1) x d(-1)), the Danqi Piantan capsule without antelope horn and with double artificial bezoar (DPCDB) group (0.246 g x kg(-1) x d(-1)). The MCAO model was prepared 1 h later after the administration on the 5th day. At 24 h after the operation, the inner canthus blood was collected to determine the serum superoxide dismutase (SOD) activity and the endothelin (ET) content. At 72 h after the operation, the cerebral infarct size and the cerebral index were determined by TTC-staining. The fluorescent quantitative PCR method was used to detect brain Bcl-2, Caspase-3, IL-1β, P-selectin, E-selectin, ICAM-1 mRNA expressions. The mmunohistochemical method was used to detect ICAM-1, IL-1β, TNF-α, IL-6 expressions in ischemic penumbra. According to the results, compared with the model group, DPCDB and DPC groups showed almost consistent results, indicating both of the two group can significantly improved cerebral infarction index and cerebral index (P < 0.05), increase the serum SOD activity (P < 0.05), decrease the serum ET level and Caspase-3 expression, IL-1β, P-selectin, E-selectin, ICAM-1 mRNA expressions in brain tissues (P < 0.05) and expressions of ICAM-1, IL-1,6, TNF-α, IL-6 positive cells in ischemic penumbra (P < 0.05) and increase the Bcl-2 expression (P < 0.05). The DPCRA group showed much lower impacts on indexes than DPCDB and DPC groups. This suggests that DPCDB and DPC reveal similar efficacies and antelope horn in Danqi Piantan capsule can be substitutes by artificial bezoar.
