Acupuncture combined with auricular point sticking for girls aged 3-8 years with incomplete precocious puberty: a randomized controlled trial / 中国针灸

OBJECTIVE@#To observe the efficacy and safety of acupuncture combined with auricular point sticking for girls aged 3-8 years with incomplete precocious puberty (IPP).@*METHODS@#Sixty girls with IPP were randomly divided into an observation group (30 cases, 2 cases dropped off) and a control group (30 cases, 2 cases were eliminated). The girls in the control group were treated with healthy diet and proper exercise for 12 weeks. On the basis of the treatment in the control group, the girls in the observation group were treated with acupuncture combined with auricular point sticking. The acupuncture was applied at Sanyinjiao (SP 6), Guanyuan (CV 4), Guilai (ST 29), etc., the needles were retained for 20 min, acupuncture was given twice a week (once every 3 days). The auricular point sticking was applied at Luanchao (TF2), Neishengzhiqi (TF2), Neifenmi (CO18), Yuanzhong (AT2,3,4i), etc., twice a week. The treatment was given for 12 weeks. Before treatment, after treatment and in follow-up after 12 weeks of treatment completion, the Tanner stage of breast, serum contents of sex hormone (luteinizing hormone [LH], follicle-stimulating hormone [FSH], estradiol [E2]) were observed. The ovarian volume, the number of follicles with diameter>4 mm, and the uterine volume were measured by abdominal color Doppler ultrasound. In addition, the safety of the observation group was evaluated.@*RESULTS@#Compared with before treatment, the Tanner stage of breast in the observation group was improved after treatment and in follow-up (P<0.05); after treatment and in follow-up, the Tanner stage of breast in the observation group was better than that in the control group (P<0.05). Compared with before treatment, the serum levels of LH and E2 in the observation group were increased (P<0.05), and the volume of bilateral ovaries was larger (P<0.05) in follow-up. Compared with before treatment, the serum contents of LH, FSH and E2 in the control group were increased (P<0.05), the volume of bilateral ovaries was larger (P<0.05), and the number of follicles was increased (P<0.05) after treatment and in follow-up. The serum levels of LH, FSH and E2 in the observation group were lower than those in the control group (P<0.05), the volume of bilateral ovaries was smaller than that in the control group (P<0.05), and the number of follicles was lower than that in the control group (P<0.05). Compared with before treatment, the uterine volume in the two groups was larger in follow-up (P<0.05). There was no statistically significant difference between the two groups after treatment and in follow-up (P>0.05). During the treatment, 3 cases in the observation group had slight abdominal pain and subcutaneous blood stasis, without serious adverse reactions.@*CONCLUSION@#Acupuncture combined with auricular point sticking could improve the Tanner stage of breast, reduce the level of sex hormone, slow down the development and maturation of ovary and follicle, and control the degree and speed of sexual development in girls aged 3-8 years with IPP.

Pathogenic characterization of Klebsiella pneumoniae resistant to carbapenems and polymyxin / 中华预防医学杂志

Objective: Analysis and investigation of pathogenic characteristics of polymyxin-and carbapenem-resistant Klebsiella pneumoniae (PR-CRKP). Methods: A total of 23 PR-CRKP strains isolated from clinical specimens from the General Hospital of Southern Theater Command from March 2019 to July 2021 were retrospectively collected, Whole-genome sequencing was performed on 23 PR-CRKP strains, resistance genes were identified by comparison of the CARD and the ResFinder database, high-resolution typing of PR-CRKP strains was analyzed by core genomic multilocus sequencing (cgMLST) and single nucleotide polymorphism (SNP); polymyxin resistance genes were determined by PCR and sequencing. Results: All PR-CRKP strains were KPC-2 producing ST11 types. cgMLST results showed that the evolutionary distance between the PR-CRKP strains and Klebsiella pneumoniae in mainland China was 66.44 on average, which is more closely related than foreign strains; the 23 PR-CRKP strains were divided into 3 main subclusters based on SNP phylogenetic trees, with some aggregation among Clade 2-1 in the isolation department and date. The two-component negative regulatory gene mgrB has seven mutation types including point mutations, different insertion fragments and different insertion positions. Conclusion: The close affinity of PR-CRKP strains indicate the possibility of nosocomial clonal transmission and the need to strengthen surveillance of PR-CRKP strains to prevent epidemic transmission of PR-CRKP.

Evaluation of genetic diversity of ginseng fruit color germplasm resources: based on SSR analysis / 中国中药杂志

Illumina Xten was employed for shallow sequencing of Panax ginseng(ginseng) samples, MISA for screening of SSR loci, and Primer 3 for primer design. Polymorphic primers were screened from 180 primers. From the successfully amplified polymorphic primers, 15 primers which featured clear peak shape, good polymorphism, and ease of statistics were selected and used to evaluate the genetic diversity and germplasm resources of 36 ginseng accessions with different fruit colors from Jilin province. The results showed that red-fruit ginseng population had high genetic diversity with the average number of alleles(N_a) of 1.031 and haploid genetic diversity(h) of 0.172. The neighbor-joining cluster analysis demonstrated that the germplasms of red-fruit and yellow-fruit ginseng populations were obviously intermixed, and pick-fruit ginseng germplasms clustered into a single clade. The results of STRUCTURE analysis showed high proportion of single genotype in pick-fruit ginseng germplasm and abundant genotypes in red-fruit and yellow-fruit ginseng germplasms with obvious germplasm mixing. AMOVA revealed that genetic variation occurred mainly within populations(62.00%, P<0.001), and rarely among populations(39%, P<0.001), but homogenization was obvious among different populations. In summary, pink-fruit ginseng population may contain rare genotypes, which is the basis for breeding of high-quality high-yield, and multi-resistance varieties, genetic improvement of varieties, and sustainable development and utilization of ginseng germplasm resources.

According to the analysis of research institutions, National Institutes for Food and Drug Control and China Pharmaceutical University possessed the largest number of Chinese and English papers, respectively, but there was less cooperation between them. The analysis of keywords in Chinese and English papers showed that the research contents of the safety of T. wilfordii mainly focused on clinical monitoring, mechanism, dosage form improvement, quality standard, component analysis, monomer research, efficiency and toxicity reduction, etc. Metabonomics, tripterine, and the underlying mechanism of toxicity were the research hotspots in the future. At present, the research on the toxicity of T. wilfordii is still under development. It is necessary to highlight the in-depth research and strengthen the inter-group and inter-region cooperation of authors or institutions to provide references for the research on the toxicity of T. wilfordii.

Application of teaching method for the interpretation of acupoint names in the course of Science of Meridians and Acupoints / 中国针灸

The paper summarizes the valuable experience of the famous teachers of all generations in the teaching & research room of meridians and acupoints of Beijing University of CM. The shortcomings are presented when the acupoints are explained in accordance with the flowing route of meridians in classroom teaching of Science of Meridians and Acupoints. Hence, it is proposed that the acupoint names should be interpreted specially for the acupoints distributed on the same meridians or adjacent ones. It is suggested to emphasize the correlation of each acupoint with its adjacent ones from the perspective of the cultural connotation of acupoint names, and then, the differences and similarities in their clinical indications can be analyzed. Eventually, a new approach to the classroom teaching of Science of Meridians and Acupoints may be provided to guide the excavation of traditional cultural connotation and establish the cultural self-confidence and professional identity.

Cadmium-induced hormesis effect in medicinal herbs improves the efficiency of safe utilization for low cadmium-contaminated farmland soil.

Compared to other soil remediation technologies, Cd-contaminated farmland soil with low cadmium accumulation (LCA) plant-based safe utilization is more catered to developing countries with food in high demand. Hormesis, which describes the fortification of plant growth performance by a low level of environmental stress, can be innovatively used to achieve increases in crop yield and plant functional components, thus amplifying the safe utilization efficiency of low Cd-contaminated soil by LCA plants. In the present study, the growth and physiological responses of Polygonatum sibiricum, a traditional Chinese medicinal herb, were investigated under laboratory conditions of gradient Cd dosage concentrations and times. As a result, the growth performance of P. sibiricum reached the peak of an inverse U-shaped curve of hormesis under e0 mg kg-1 and 9 months of Cd stress, with elevations in tuber biomass (medicinal part), plant height and polysaccharide content (medicinal components) of 143%, 25% and 90%, respectively. Meanwhile, trace Cd accumulation (0.41 mg kg-1) in the tuber guaranteed medicinal edible safety. In addition, Cd-induced hormesis in P. sibiricum was verified to be overcompensated by antioxidation systems. In conclusion, such 'win-win' results, including low Cd accumulation and enhancement of plant pharmaceutical value, provided medicinal herbs with a possibility for safe soil utilization.

Effects and mechanisms of nitrogen fertilizers on soil and tritrophic interactions in Chinese medicinal plants ecosystem / 中国中药杂志

Nitrogen is one of the most frequently used fertilizers in growth of Chinese medicinal plants(CMP). As in many other ecosystems, CMP ecosystem is also composed of plant-herbivore-natural enemy(tritrophic) interactions. Nitrogen fertilizer influences the growth and reproduction of CMP, and it is also able to heavily shape the ecosystem functions of CMP ecosystem through bottom-up forces. Understanding the specific effects of nitrogen fertilizer towards each trophic level will be beneficial to improve the resistance of CMP to herbivore and enhance the control efficiency of nature enemies to herbivore, and eventually, maximize the yield and quality of CMP. Most papers published on nitrogen use in plants focused mainly on the impact of nitrogen fertilization on CMP yield and quality. Influences of nitrogen application on CMP ecosystem get little attention at present. Therefore, this review summed up the potential effects of nitrogen fertilization on CMP ecosystem from perspectives of soil and tritrophic interactions. First of all, nitrogen fertilizer might decrease soil microbial biomass and altered the community structures of soil bacteria, fungi and protozoa. Negative effects of nitrogen fertilizer were found on biodiversity of soil bacteria and protozoa. Different fungi species respond differently to nitrogen fertili-zers. Nitrogen deposition can also decrease the soil pH. Decreases in soil microbial diversity and soil acidification can cause negative effects on CMP growth. In addition, nitrogen fertilizer could regulate the pest resistance of CMP including constitutive and inducible resistance. Both positive and negative effects of nitrogen application were found on pest resistance of CMP. Moreover, the development and predation of natural enemies were influenced by nitrogen deposition. Nitrogen influences natural enemies in many ways including plant volatiles, plant nutrient and structure and the supplementary food quality. Nectar and honeydew of plants and preys serve as important food source for natural enemies especially in early season when preys are still not available. Finally, the interactions between herbivores and their natural enemies were also shaped by nitrogen fertilizer in many aspects like increasing the nutritional content of prey and changing control efficiency of natural enemies. Some herbivores have evolved a strategy to sequester secondary metabolites which they absorbed from plant during their feeding. Studies showed that sequestration efficiency of secondary metabolites in prey could also be regulated by nitrogen. Parasitic, emergence, reproduction rate and longevity of parasites were found positively correlated with nitrogen deposition. Hopefully this study will shed light on practicable and economical application of nitrogen in cultivation of CMP.

Objective:To investigate the clinical efficacy of infra-acetabular screwing in the treatment of acetabular fractures.Methods:A retrospective analysis was conducted of the 22 patients with acetabular fracture who had been admitted to Department of Trauma and Orthopedics, The Affiliated Hospital of Traditional Chinese Medicine, Xinjiang Medical University from January 2016 to January 2019. They were 16 males and 6 females, aged from 19 to 65 years (mean, 45.2 years). According to Letournel-Judet classification, there were 2 anterior column fractures, 12 anterior plus posterior hemi-transverse fractures, 3 T-shaped fractures and 5 both-column fractures. All patients were treated with infra-acetabular screwing through the ilioinguinal approach. Recorded were the patients＇ operation time, intraoperative blood loss, reduction quality, fracture union time, hip function and complications.Results:Operation time for this cohort ranged from 115 to 285 min (mean, 160 min), and intraoperative blood loss from 360 to 1,600 mL (mean, 650 mL). By the Matta scoring, fracture reduction was assessed as excellent in 14 cases, as good in 5 cases and as poor in 3 cases, giving an excellent and good rate of 86.4% (19/22). Of this cohort, 21 were followed up from 12 to 45 months (mean, 28.5 months) and one was lost to the follow-up. The fracture healing time for 21 patients ranged from 1.6 to 3.0 months, averaging 2.2 months. No patient had fracture displacement. The Merle d’Aubigné & Postel hip scores at the last follow-up ranged from 8 to18 points (average, 16 points), giving 12 excellent, 6 good, 2 fair, and one poor cases and an excellent and good rate of 85.7% (18/21). Follow-ups observed injury to the lateral femoral cutaneous nerve in one case, deep venous thrombosis of lower limb in 2 cases, superficial wound infection in one case and traumatic arthritis in one case, yielding a total rate of compilations of 23.8% (5/21).Conclusion:Application of infra-acetabular screwing after anatomical reduction of an acetabular fracture can effectively enhance the strength of internal fixation with no risk of fracture re-displacement, conducive to early functional exercise of the patient and leading to good clinical efficacy.

[Comparison of therapeutic effect of moxibustion materials from different places and storage periods on knee osteoarthritis].

Osteoarthritis(OA) is a kind of osteoarticular degenerative disease. The most common joint involvement of OA is knee and hip joint. The incidence rate of OA increases with age. Meta analysis shows that moxibustion is superior to other therapies in treating knee osteoarthritis(KOA). In this study, the effects of moxibustion materials from different places of origin(Hubei Qichun, Henan Nanyang, Hunan) and storage periods(5, 3, 1 years) on knee osteoarthritis in rats were compared. The swelling degree of knee joint and the histopathology of knee joint cartilage were measured. The mechanism of moxibustion in the treatment of knee osteoarthritis was discussed from the perspective of Wnt/ß-catenin signaling pathway. The results showed that the swelling degree of knee joint in the moxibustion material group of Hubei Qichun and Henan Nanyang was significantly lower than that in the model group, the diffe-rence was statistically significant(P<0.05), and it was better than that in the moxibustion material group of Hunan Province; compared with the model group, the degeneration and pathological change of knee joint cartilage tissue in the moxibustion material group of different origins were alleviated to different degrees, the Mankin's score was significantly reduced, and that in the moxibustion material group of Qichun in Hubei Province and Nanyang in Henan Province was significantly reduced and better than Hunan moxibustion material group. The effect of moxibustion materials with different storage years on the swelling degree of osteoarthritis in rats was the earliest in Qichun 5-year group, and there was significant difference between Qichun 5-year group and model group after 3 days of treatment; the improvement of histopathological changes in Qichun 5-year and 3-year moxibustion materials group was better than that in Qichun 1-year moxibustion materials group. The study on the mechanism of action showed that moxibustion materials from different places could reduce the mRNA expression of ß-catenin, BMP-2, MMP-3, MMP-9 and MMP-13 genes in knee cartilage, suggesting that moxibustion could inhibit cartilage base by regulating Wnt/ß-catenin signal pathway. It may be one of the mechanisms of moxibustion in the treatment of OA.

Effects of electroacupuncture of different frequencies on electromyography, NOS and ICC of colon in rats with slow transit constipation / 针灸推拿医学（英文版）

Objective: To observe the effects of electroacupuncture (EA) of different frequencies on transmission function, electromyography, nitric oxide synthase (NOS) content and interstitial cells of Cajal (ICC) expression of colon in rat models with slow transit constipation (STC). Methods: Of the 50 healthy male Wistar rats, 10 were randomly selected as a normal group and fed with ordinary diet, and the remaining 40 rats were fed with the diet added with the compound diphenoxylate at a dose of 8 mg/(kg·bw) each day for continuous 120 d. The 40 successfully established STC rat models were randomly divided into a model group, a low-frequency EA group (2 Hz), a high-frequency EA group (100 Hz), and a variable-frequency EA group (2 Hz/100 Hz), with 10 rats in each group. Rats in the normal and the model groups were not given any treatment; the low-frequency EA and the high-frequency EA groups were given EA at Tianshu (ST 25), Zusanli (ST 36) and Zhigou (TE 6) with continuous wave at the designated frequency, and the variable-frequency EA group received sparse-dense wave (2 Hz/100 Hz) EA at the same acupoints, once a day for a total of 15 d. After treatment, the colonic transmission function, electromyography, NOS content and ICC expression (calculated by the difference in the area of the C-kit positive cells) of the rats in each group were measured. Results: For the colonic transmission function, compared with the normal group, the first black stool excretion durations of rats in the other groups were significantly prolonged (all P<0.05); compared with the model group, the first black stool excretion durations of rats in the three EA groups were significantly shortened (all P<0.05), which was significantly shorter in the variable-frequency EA group than in the low-frequency EA and high-frequency EA groups (both P<0.05). For the colonic electromyography, compared with the normal group, the amplitude was significantly increased and the frequency was accelerated in rats of the other groups (all P<0.05); compared with the model group, the amplitude was significantly reduced and the frequency was slowed down in the three EA groups (both P<0.05); compared with the low-frequency EA and the high-frequency EA groups, the amplitude was reduced and the frequency was significantly reduced in rats of the variable-frequency EA group (both P<0.05). Compared with the normal group, the colonic NOS contents were significantly increased in the other groups (all P<0.05); compared with the model group, the NOS contents were significantly reduced in the three EA groups (all P<0.05); compared with the low-frequency EA and the high-frequency EA groups, the content was significantly reduced in the variable-frequency EA group (all P<0.05). For the area of rat colonic C-kit-positive cells, compared with the normal group, the areas were significantly reduced in rats of other groups (all P<0.05); compared with the model group, the areas were increased significantly in the three EA groups (all P<0.05); compared with the low-frequency EA group, the area was increased significantly in the variable-frequency EA group (P<0.05). Conclusion: EA, especially EA at the 2 Hz/100 Hz variable-frequency, has a positive treatment effect on the STC model rats. It may improve rats' colonic function by regulating the electromyography, NOS content and ICC expression of colon.

Correlation Analysis of " Toxin Damaging Brain Collaterals" from Glymphatic System / 中国实验方剂学杂志

The collaterals are branches of the meridians and vessels system, and have the roles of connecting upper-lower and interior-exterior portions of the body, the characteristics of two-way flow in supporting the operation of Qi and blood, and the functions of material exchange and metabolism. The brain is the intersection of the Yang meridians. Crisscross brain collaterals permeate Qi and blood to enrich the brain, and spread Yang Qi, in order to warm the brain-mind, and provide material basis and source power to the " brain governing mind" . Under pathological conditions, cerebral collaterals are blocked, and toxic pathogens are endogenous, resulting in " toxin damaging brain collaterals" . This theory is not only applied to the study of stroke pathogenesis, but also extended to other encephalopathy, such as dementia, which promoted the development of the theory of pathogenesis in traditional Chinese medicine. Recently, a " glymphatic system" was discovered in the brain, which is an exchange flow system of cerebrospinal fluid-brain interstitial fluid mediated by astrocyte. The glymphatic system transports nutrients and neuroactive substances, such as glucose, lipids, electrolytes and apolipoprotein E in the cerebrospinal fluid, to brain tissue, and also removes metabolic products (such as lactic acid), soluble proteins (such as β-amyloid protein and Tau protein) from the brain and foreign bodies, which are important liquid flow systems that maintain the homeostasis of the brain. The discovery of the glymphatic system provides a new perspective for the study of pathological mechanism of neurological diseases, and may become a new target for interventions in neurological diseases, such as cerebrovascular diseases and neurodegenerative diseases. As a widely distributed cerebral metabolic waste removal way and material delivery system, the lymphatic system may be the biological foundation of " brain collateral" disease, and a cross point of understanding on " toxin impairing brain collaterals" by Western and traditional Chinese medicine. The study based on the glymphatic system will give a more rational explanation on " toxic damage to brain collaterals" .

Pathogenesis of Metabolic Syndrome from "Qi of five Internal Organs" / 中国实验方剂学杂志

Metabolic syndrome (MS) is a group of syndromes caused by the disorder of metabolism of various substances in the body. The main clinical manifestations are dyslipidemia, central obesity, hypertension, abnormal glucose tolerance and insulin resistance. With the changes of diet structure and habits, the incidence rate of MS is increasing, and the patients are younger. It is an important factor in many diseases, such as diabetes, atherosclerosis, coronary heart disease, hyperlipidemia, cirrhosis and some cancers. MS has seriously affected people's lives and health. Central obesity and insulin resistance are recognized as important pathogenic factors. At present, the pathogenesis of MS and its components has not been fully understood. The clinical manifestations of metabolic syndrome are complex and diverse. Traditional Chinese medicine (TCM) believes that the occurrence of metabolic syndrome is related to such factors as proper diet, emotional disorders, excessive escape and little movement, old age and physical deficiency. TCM scholars have studied the pathogenesis of MS in such pathological factors as phlegm and blood stasis, such visceral functions as liver, spleen and kidney, roles of Qi and blood, and emotional factors. As the basic substance of organism, Qi is closely related to the process of metabolism. The occurrence of MS is closely related to the rise and fall of Qi moving to and from the body as well as the abnormal gasification function of the transformation of Qi. Qi is derived from the five internal organs, which are respectively called Heart Qi, liver Qi, spleen Qi, lung Qi and kidney Qi. The "Qi of the five internal organs" is involved in the whole process of the generation, transportation and excretion of the essence of the body. Based on the "Qi of five internal organs", this paper discusses the pathogenesis of MS with phlegm, blood stasis and water drink as pathological factors.

Pattern and matching technology of ecological planting for Chinese materia medica based on system level / 中国中药杂志

The ecological agriculture of Chinese materia medica(CMM) has become the most dynamic and promising new field in the global ecological agriculture. The development of ecological planting of CMM has become the national strategy of Chinese traditional medicine agriculture. It has been highly valued and has flourished throughout the country, and has formed some more mature ecological planting models of CMM. Based on the system level, this paper sorts out the common ecological cultivation patterns of CMM, and obtains five basic patterns: landscape pattern at the ecological landscape level, circulation pattern at the ecosystem level, stereo model at the bio-community level, biodiversity patterns at the level of biological populations and well-established models at the level of biological individuals. On this basis, eight common ecological planting techniques of CMM were obtained, includingwild tending techniques, fine agricultural farming techniques, directional cultivation techniques, soil improvement techniques, soil testing and fertilization techniques, mycorrhizal cultivation techniques, green control technology for pests and diseases and facility cultivation techniques.This paper aims to provide theoretical basis for scientific research and popularization and application of CMM ecological planting.

Pattern of ecological planting for Chinese materia medica based on regional distribution / 中国中药杂志

As an environment-friendly agriculture, ecological agriculture of Chinese materia medica(CMM) is being implemented in all parts of the country. Due to the stronger dependence on natural environmental conditions, ecological agriculture of CMM shows obvious regional differences in production practice. More mature CMM ecological planting patterns representative of each region were collected. It was found that common types of patterns in various regions of the country mainly included intercropping,intercropping,rotation planting mode, undergrowth planting mode, wild tending planting mode and landscape ecological planting mode. Based on the Construction Plan of National Dao-di Herbs Production Base(2018-2025) and Chinese Medicine Division, this paper systematically sorts out the pattern of ecological planting of CMM in the 8-avenue medicinal materials production areas according to the varieties and regions. The specific pattern of ecological planting of CMM included the ginseng undergrowth planting pattern in northeastern China, the bionics wild ecological planting of the Forsythia suspensa in northern China, the Fritillaria thunbergii-rice rotation in eastern China, the imitation wild planting pattern under the Polygonatum cyrtonema in central China, the planting pattern of the Fructus amomi under forest in southern China, the Ligusticum chuanxiong-rice rotation pattern in the Southwest, wild tending of Glycyrrhiza uralensis in the Northwest, and rhubarb imitation wild planting pattern in Qinghai-Tibet area. Finally, it is expected to provide reference for the screening and popularization of ecological planting patterns of other CMMs in various distribution areas.

Chinmedomics facilitated quality-marker discovery of Sijunzi decoction to treat spleen qi deficiency syndrome / 医学前沿

Sijunzi decoction (SJZD) is a Chinese classical formula to treat spleen qi deficiency syndrome (SQDS) and has been widely used for thousands of years. However, the quality control (QC) standards of SJZD are insufficient. Chinmedomics has been designed to discover and verify bioactive compounds of a variety of formula rapidly. In this study, we used Chinmedomics to evaluate the SJZD's efficacy against SQDS to discover the potential quality-markers (q-markers) for QC. A total of 56 compounds in SJZD were characterized in vitro, and 23 compounds were discovered in vivo. A total of 58 biomarkers were related to SQDS, and SJZD can adjust a large proportion of marker metabolites to normal level and then regulate the metabolic profile to the health status. A total of 10 constituents were absorbed as effective ingredients that were associated with overall efficacy. We preliminarily determined malonyl-ginsenoside Rb2 and ginsenoside Ro as the q-markers of ginseng; dehydrotumulosic acid and dihydroxy lanostene-triene-21-acid as the q-markers of poria; glycyrrhizic acid, isoglabrolide, and glycyrrhetnic acid as the q-markers of licorice; and 2-atractylenolide as the q-marker of macrocephala. According to the discovery of the SJZD q-markers, we can establish the quality standard that is related to efficacy.

Effect of fresh Gastrodia elata on gut microbiota in mice / 中国中药杂志

Gastrodia elata B1.,a traditional Chinese medicine,was frequently applied as a cure for headache or migraine. Its effects include suppressing hyperactive liver,calming endogenous wind,dredging collateralsand relieving spasm. There has been a proportion that G. elata should be added to The List of Substances That Are Traditionally Both Food and Chinese Medicinal Materials. The dry G. elata was commonly used in clinic,which have some fundamental study on efficacy and mechanism. However,fresh G. elata,which was added to herbal cuisine very often,lacks corresponding research. The interaction of diet,microbiota and human is a hot issue and lots of scholars are focusing on it. This research sequenced the 16 S rRNA of mouse cecal contents on Mi Seq platform to understand the effect of taking fresh G. elata. As the results showing,multiple probiotics grew after taking fresh G. elata extract,including Ruminiclostridium,Butyricicoccus,and Parvibacter. To contrast,some pathogens or potential pathogens,such as Escherichia/Shigella,Parasutterella,decreased. This manifests that fresh G. elata performs a positive regulation on mouse gut microbiota,especially the low-dose fresh G. elata extraction could restructure the microbiota apparently. Our result reveals that microbiota might be a new target for G. elata extract and provides an important basis for further research on the interaction between gut microbiota and pharmacological activity of G. elata.
