This study aimed to investigate the anti-fatigue effect and mechanism of Lubian(Cervi Penis et Testis) on kidney Yin deficiency and kidney Yang deficiency mice. After one week of adaptive feeding, 88 healthy male Kunming mice were randomly divided into a blank group, a kidney Yin deficiency model group, a kidney Yin deficiency-Panacis Quinquefolii Radix(PQR) group, kidney Yin deficiency-Lubian treatment groups, a kidney Yang deficiency model group, a kidney Yang deficiency-Ginseng Radix et Rhizoma(GR) group, and kidney Yang deficiency-Lubian treatment groups, with eight mice in each group. The kidney Yin deficiency model and kidney Yang deficiency model were prepared by daily regular oral administration of dexamethasone acetate and hydrocortisone, respectively, and meanwhile, corresponding drugs were provided. The mice in the blank group received blank reagent. The treatment lasted 14 days. The exhaustive swimming time was measured 30 min after drug administration on the 14th day. On the 15th day, blood was collected from eyeballs and the serum was separated to determine the content of lactic acid(LD), blood urea nitrogen(BUN), lactate dehydrogenase(LDH), cyclic adenosine monophosphate(cAMP), and cyclic guanosine monophosphate(cGMP). The liver was dissected to determine the content of liver glycogen and the protein expression of phosphoinositide 3-kinase(PI3K) and protein kinase B(Akt). Compared with the kidney Yang deficiency model group, the kidney Yang deficiency-Lubian treatment groups showed increased body weight(P<0.05), relieved symptoms of Yang deficiency, decreased cGMP content(P<0.01), increased cAMP/cGMP(P<0.01), prolonged exhausted swimming time(P<0.01), reduced LD(P<0.01), elevated BUN content(P<0.01), increased liver glycogen content(P<0.01), and increased protein expression of PI3K and Akt in the liver(P<0.05). Compared with the kidney Yin deficiency model group, the kidney Yin deficiency-Lubian treatment groups showed increased body weight(P<0.01), relieved symptoms of Yin deficiency, increased content of cGMP(P<0.01), decreased cAMP/cGMP(P<0.01), prolonged exhausted swimming time(P<0.01), decreased LD(P<0.01), decreased BUN content(P<0.01), increased liver glycogen content(P<0.01), and increased protein expression of PI3K(P<0.05) and Akt in the liver(P<0.05). To sum up, Lubian can regulate Yin deficiency and Yang deficiency and increase glycogen synthesis by affecting the PI3K-Akt pathway, thereby exerting an anti-fatigue role.

Properties of new exotic traditional Chinese medicinal Vernonia amygdalina leaves:a literature research / 中国中药杂志

The leaves of Vernonia amygdalina Delile of the family Asteraceae(also known as "bitter leaf"), rich in biological activities, are used as both medicine and food for a long time in West tropical Africa. They have been introduced into Southeast Asia and Fujian and Guangdong provinces of China in recent years. However, little is known about the properties of the plant in traditional Chinese medicine(TCM), which limits its combination with other Chinese medicinal herbs. In this study, 473 articles on V. amygdalina leaves were selected from PubMed, Web of Science, CNKI, Wanfang Data and VIP to summarize their components, pharmacological effects and clinical research. V. amygdalina leaves presented anti-microbial, hypoglycemic, anti-hypertensive, lipid-lowering, anti-tumor, anti-inflammatory, antioxidant, and other pharmacological effects. On the basis of the theory of TCM properties, the leaves were inferred to be cold in property and bitter and sweet in flavor, acting on spleen, liver, stomach and large intestine and with the functions of clearing heat, drying dampness, purging fire, removing toxin, killing insects and preventing attack of malaria. They can be used to treat dampness-heat diarrhea, interior heat and diabetes, malaria, insect accumulation and eczema(5-10 g dry leaves by decoction per day and an appropriate amount of crushed fresh leaves applying to the affected area for external use). Due to the lack of TCM properties, V. amygdalina leaves are rarely used medicinally in China. The determination of medicinal properties of the leaves is conducive to the introduction of new exotic medicinal herbs and the development of new TCM resources, which facilitated further clinical application and research and development of Chinese medicinal herbs.

Traditional Chinese medicine health care from "long term taking" drugs in Shen Nong's Classic of Materia Medica / 中国中药杂志

"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.

Finally, compared with the model group, the expressions of nNOS mRNA of paeoniflorin groups(30 mg•kg⁻¹ and 15 mg•kg⁻¹) (P<0.01, P<0.01) and albiflorin groups(30 mg•kg⁻¹) were significantly decreased(P<0.05). Compared with the model group, the protein exprsssions of BDNF of paeoniflorin group(30 mg•kg⁻¹) and albiflorin group(30 mg•kg⁻¹) were obviously increased(P<0.05). Albiflorin and paeoniflorin have the effects of smooth the liver and dispel stagnation, the mechanism has the relevant with adjusting and controlling the expression of NO and BDNF in hippocampus.

Effects of Shaoyao Gancao decoction on contents of amino acids and expressions of receptors in brains of spastic paralysis rats / 中国中药杂志

To explore the effects of Shaoyao Gancao decoction on contents of amino acids and expressions of receptors in the brains of spastic paralysis rats, the spastic paralysis rat models of stroke convalescence were made by line tethering method. Baclofen was used as the control group, and the experiment group received Shaoyao Gancao decoction at 3∶1 proportions. After 3 weeks, the neurobehavioral scores, muscular tension and pain threshold were measured and compared. High performance liquid chromatography (HPLC) was used to detect the contents of GABA, Gly, Glu, Asp in cerebral cortex. The protein expressions of GABA receptors Aα1, B； NMDA receptor NR1, NR2A and NR2B in cerebral cortex were determined by immunohistochemistry assay. The results showed that the Shaoyao Gancao decoction at 3∶1 proportion could improve the spastic paralysis state after stroke, significantly improve neurological symptoms (P<0.01), decrease muscular tension (P<0.01) and improve pain threshold (P<0.05) as compared with model group. Simultaneously, the contents of inhibitory amino acids GABA and Gly were increased significantly (P<0.01), while with a decrease tendency in excitatory amino acids Glu and Asp (with no statistical significance). In addition, it could significantly increase the protein expressions of neurotransmitter GABA receptors Aα1, and B (P<0.05); reduce the expressions of neurotransmitter NMDA receptors NR1, NR2A and NR2B (P<0.05). These results suggested that the Shaoyao Gancao decoction at 3：1 proportion could effectively relieve spasm and pain. The mechanism might be associated with increasing the contents of inhibitory amino acids and increasing the expressions of their receptors in spastic paralysis rats after stroke, which would consequently enhance the signal transduction of inhibitory amino acids. Meanwhile, there was a decrease tendency in excitatory amino acids, although no significant effect was observed, and it could suppress the expressions of excitatory amino acids receptors, thus weaken the excitatory signal transduction. Thereby the neurotoxicity was relieved eventually. These findings indicated that Shaoyao Gancao decoction could regulate the balance of neurotransmitter system to relieve the spasticity, and eventually achieve tendon tonifying and spasm relieving effect.
