ABSTRACT

As a Chinese saying goes, "good Chinese medicinal material makes good medicine", the quality of Chinese herbal medicines is related to the development prospect of Chinese medicine industry in China. With the rapid development of new technologies such as traceability methods and monitoring instruments, it is imperative to integrate and innovate traditional Chinese herbal medicines with new-generation information technology in view of the quality problems existing in the current production and circulation of Chinese herbal medicines, and it is of great significance for the construction of traceability system to ensure the quality and safety of Chinese herbal medicines and to promote the industry of Chinese herbal medicines to move towards high-quality development. This paper reviews the development history of the traceability system of Chinese herbal medicines in China, takes the influencing factors of the quality of Chinese herbal medicines as the entry point, and proposes that the construction of the traceability system should satisfy the traceability requirements of the characteristics of Chinese herbal medicines and their traditional medication experience. By analyzing the influencing factors of the quality of Chinese herbal medicines, it is pointed out that focusing on the influencing factors to build a traceability system is of great significance for targeting the problematic links at a later stage and exploring the interrelationship between environmental factors and the quality of Chinese herbal medicines. Based on the previous explorations, the author summarizes the system framework, functional modules and practical applications of the traceability system of Chinese herbal medicines, and looks forward to the development of a traceability system with risk early warning function and expert decision-making function in its functional development. Finally, based on the factors affecting the quality of Chinese herbal medicines, the author puts forward several thoughts on construction of the traceability system, and makes an in-depth analysis and puts forward a solution for the current situation that a unified, standardized and universal traceability system has not yet been built, with a view to providing ideas and references for the construction of traceability system of Chinese herbal medicines.

ABSTRACT

ObjectiveTo explore the mechanism of Zhuangyao Tongluo Formula(壮腰通络方,ZTF) in delaying intervertebral disc degeneration. MethodsM1 macrophages were induced from THP-1 cells using LPS, IFN-γ and PMA. The induced M1 macrophages were then co-cultured with nucleus pulposus cells in a transwell system. Fetal bovine serum was used as the control serum, and the effects of different concentrations (5%, 10%, 15%, 20%) of serum from rats treated with ZTF on the activity of M1 macrophages and nucleus pulposus cells were analyzed using MTT assay. Experiment 1 was established, including the nucleus pulposus cell control group, M1 macrophage control group, nucleus pulposus cell + ZTF group, nucleus pulposus cell + TNF control group, nucleus pulposus cell + TNF + ZTF group, co-culture group, and co-culture + ZTF group. The levels of IL-1β, and IL-18 in the culture supernatant were detected using ELISA. The mRNA expression of IL-1β and IL-18 in nucleus pulposus cells was detected using qPCR. Additionally, the expression of GSDMD protein in nucleus pulposus cells was detected using cell immunofluorescence. In experiment 2, co-culture groups were constructed using TNF-α overexpression (OE) or empty vector (EV) plasmids, including co-culture group, TNF-EV + co-culture group, TNF-EV co-culture group + ZTF, co-culture + ZTF group, TNF-OE co-culture group + ZTF, and TNF-OE + co-culture group. The mRNA and protein expression of TNF-α in M1 cells in each group were detected using qPCR and WB. ResultsThe ZTF with 10% serum was selected for subsequent experiments. The results of experiment 1 showed that compared to the control group of nucleus pulposus cells, there was no statistically significant difference in the levels of IL-1β, IL-18, mRNA, and GSDMD expression in the nucleus pulposus cells + ZTF group (P>0.05). However, the TNF-α + co-culture group showed a significant increase in IL-1β, IL-18 levels, mRNA, and GSDMD expression (P<0.01). When compared to the co-culture group, the ZTF+ co-culture group showed a significant decrease in IL-1β, IL-18 levels, mRNA, and GSDMD expression (P<0.01). The results of experiment 2 showed that there was no statistically significant difference in TNF-α mRNA and protein expression between the empty vector plasmids + co-culture group and the co-culture group (P>0.05). Compared to the empty vector + co-culture group, the expression of TNF-α mRNA and protein was significantly reduced in the empty vector co-culture + ZTF group (P<0.01). Compared to the co-culture group and the empty vector + co-culture group, the expression of TNF-α mRNA and protein was significantly reduced in the co-culture + ZTF group (P<0.01). Compared to the co-culture + ZTF group, the expression of TNF-α mRNA and protein significantly increased in the overexpression vector co-culture + ZTF group (P<0.01). Compared to the overexpression vector co-culture + ZTF group, the expression of TNF-α mRNA and protein significantly increased in the overexpression vector co-culture group (P<0.01). ConclusionZTF serum can inhibit the TNF-α-induced apoptosis of nucleus pulposus cells and delay lumbar disc degeneration by reducing the expression of TNF-α in M1 macrophages.

ABSTRACT

ObjectiveIn recent years, with the sharp decline of wild resources in Arisaematis Rhizoma and Pinelliae Rhizoma and the immaturity of medicinal cultivation technology, their adulterants have appeared frequently in the market, and the main identifying characteristics have mostly disappeared in the circulation of medicinal materials. Therefore, there is an urgent need to establish a molecular identification method that can quickly and effectively identify the specificity of Arisaematis Rhizoma and Pinelliae Rhizoma. MethodAfter comparison of the rbcL sequences of Arisaematis Rhizoma,Pinelliae Rhizoma, and their adulterants, the specific enzyme cleavage sites Hae Ⅲ and Dra Ⅰ of Arisaematis Rhizoma and Pinelliae Rhizoma, respectively, were selected and identified by polymerase chain reaction-restriction fragment length polymorphism(PCR-RFLP). The main system conditions of PCR-RFLP reaction were established and optimized, and their durability and the ability to detect genuine, adulterants, and mixed counterfeits were investigated. ResultThe PCR-RFLP identification method of Arisaematis Rhizoma and Pinelliae Rhizoma was established. After specific primer amplification, Arisaematis Rhizoma and Pinelliae Rhizoma could be digested by Hae Ⅲ and Dra Ⅰ-restricted endonucleases respectively, at annealing temperature of 54 ℃, the number of cycles of 35, and the amount of DNA template of 3-30 ng, producing two fragments or small cut fragments with a single band between 100-250 bp, whereas the mixed counterfeits were not cleaved and both showed a band at 250 bp. The method is highly accurate in identifying adulterants and mixed counterfeits of Arisaematis Rhizoma or Pinelliae Rhizoma. ConclusionThe PCR-RFLP method developed in this study allows for the rapid identification of Arisaematis Rhizoma and Pinelliae Rhizoma.

ABSTRACT

Fracture is one of the common diseases in the department of orthopaedics and traumatology. Jiegu Qili Tablets(Capsules) are a Chinese patent medicine commonly used to treat fractures in clinical practice, which has been included in the Class A drugs of the catalog of medicines covered by the National Medical Insurance System. However, no consensus or guideline has yet been developed to guide clinicians based on an evidence-based approach in detail, which has severely limited the clinical value of this drug. According to the guiding principle of evidence as the key, consensus as the supplement, and experience as the reference, a consensus was developed in strict accordance with the steps stipulated in the expert consensus on clinical applications of proprietary Chinese medicines. Based on literature review and questionnaire survey, the consensus was a timely summary of the existing clinical evidence on the treatment of fractures with Jiegu Qili Tablets(Capsules), and incorporated the treatment experience of a number of clinical experts. The preparation process took more than a year and the consensus(GS/CACM 293-2021) was officially released by the China Association of Chinese Medicine in September 2021, with the participation of multidisciplinary experts from 27 organizations of Chinese and Western medicine and research institutions. This article introduces the background and objectives of the consensus in detail, and describes the main process of proposal, drafting, expert consensus, and consultation. In particular, 5 consensus recommendations and 12 consensus suggestions are formed with regard to the key issues of indications, treatment timing, dose, duration, and safety in the clinical application of Jiegu Qili Tablets(Capsules) for the treatment of fractures, which guide and standardize the rational use by clinicians and improve the accuracy and safety of drugs.

ABSTRACT

With the effects of activating blood and resolving stasis, and moving Qi to relieve pain, Jingtong Granules is widely used in the treatment of cervical radiculopathy in China. Long-term clinical application and related evidence have shown that the prescription has ideal effect in alleviating the pain in neck, shoulder, and upper limbs, stiffness or scurrying numbness, and scurrying pain caused by this disease. However, there is a lack of consensus on the clinical application of Jingtong Granules. Therefore, clinical first-line experts and methodology experts from all over the country were invited to compile this expert consensus. This expert consensus is expected to guide clinicians to use Jingtong Granules in a standardized and reasonable way, improve clinical efficacy, reduce medication risks, and benefit patients. First, according to the clinical experience of experts and the standard development procedures, the indications, syndrome characteristics, clinical advantages, and possible adverse reactions of Jingtong Granules were summarized. Then, through face-to-face interview of clinical doctors in traditional Chinese medicine and western medicine and survey of the clinical application, the clinical problems were summed up, and the consensus was reached with the nominal group method to form the final clinical problems. Third, evidence retrieval was carried out for the clinical problems, and relevant evidence was evaluated. The GRADE system was employed to rate the quality of evidence. Fourth, 5 recommendation items and 3 consensuses items were summarized with the nominal group method. Opinions and peer reviews on the consensus content were solicited through expert meetings and letter reviews. The final consensus includes the summary of evidence on the clinical indications, effectiveness, and safety of Jingtong Granules, which can serve as a reference for clinicians in hospitals and primary health institutions.

ABSTRACT

OBJECTIVE@#To investigate whether Salvianolic acid A (SAA) can restore cartilage endplate cell degeneration of intervertebral discs and to identify the mechanism via regulation of micro-RNA.@*METHODS@#Cartilage endplate cells were isolated from lumbar intervertebral disc surgical samples and were treated with serum containing a series of concentrations of SAA (2, 5, and 10 ?M) for 24, 48, and 72 h to identify a proper dose and treatment time of SAA. The effect SAA on interlenkin-1β (IL-1β)-induced extracellular matrix degradation of cartilage endplate cells were analyzed by Alcian blue staining and assessment of the expression levels of ADAMTS-5, MMP3 and Col2a1. Further, the potential target miRNAs were preliminarily screened by micro-RNA sequencing combining qRT-PCR and Western blot, and then, the miRNAs mimics and inhibitors were used to verify the regulatory effect of SAA on potential target miRNAs.@*RESULTS@#The 10 μM SAA treatment for 48 h significantly enhanced the viability of cartilage endplate cells, and increased Col2a1 expression and glycosaminoglycan accumulation that were repressed by IL-1β, and reduced the effect of IL-1β on ADAMTS-5, and MMP3. Screening analysis based on micro-RNA sequencing and Venny analysis identified the downstream micro-RNAs, including miR-940 and miR-576-5p. Then, the miR-940-mimic or miR-576-5p-mimic were transfected into CEPCs. Compared with the SAA group, the expression of ADAMTS-5 and MMP3 increased significantly and the expression of COL2A1 obviously decreased after overexpression of miR-940 or miR-576-5p in CEPCs.@*CONCLUSION@#Salvianolic acid A attenuated the IL-1β-induced extracellular matrix degradation of cartilage endplate cells by targeting regulate the miR-940 and the miR-576-5p.

ABSTRACT

Objective : To study the effect of temperature and light intensity on photosynthetic fluorescence parameters, volatile oil content, and growth of Atractylodes lancea and provide reference for the rational selection of cultivation environment for A. lancea. MethodWe determined the photosynthetic indexes (such as net photosynthetic rate, water use efficiency, and carboxylation rate), light response curve, CO2 response curve, fluorescence parameters, and the content of four volatile oils in A. lancea under two temperature treatments (32 °C and 22 °C) and two light treatments (full light and shade). ResultThe net photosynthetic rate and water use efficiency of A. lancea under high temperature + strong light were significantly higher than those under high temperature + weak light and low temperature + strong light. The ability of A. lancea to use weak light at low temperature was the strongest, while the utilization rate of weak light under strong light significantly reduced. The photosynthetic rate of A. lancea at low temperature was more susceptible to light intensity and CO2 concentration than that at high temperature. The maximum photosynthetic rate and apparent quantum efficiency under weak light were significantly higher than those under strong light. The photoreaction efficiency at high temperature was higher than that at low temperature. The total amount of volatile oil in A. lancea treated with high temperature + weak light was the highest, reaching 4.582%. Compared with high temperature + strong light, high temperature + weak light significantly increased the content of hinesol and β-eudesmol in A. lancea by 91.7% and 35.7%, respectively, and low temperature + strong light significantly increased the content of hinesol by 87.5%. The content of β-eudesmol in low temperature + weak light treatment was significantly lower than that in high temperature + weak light treatment. ConclusionTThe growth of A. lancea was affected by the interaction between temperature and light. The light and temperature conditions required for the accumulation of volatile oil were not consistent with those suitable for the growth and development of A. lancea. A. lancea responded to the changes of light and temperature conditions by regulating the synthesis and accumulation of volatile oil.

ABSTRACT

Traditional Chinese medicine has unique advantages in the treatment of degenerative bone and joint diseases, and its widely used in clinical practice. In recent years, many scholars have conducted a large number of basic studies on the delay of intervertebral disc degeneration by herbal compound and monomeric components from different perspectives. In order to further elucidate its mechanism of action, this paper summarizes the in vivo and in vitro experimental studies conducted at the level of both herbal compound and single components, respectively, in order to provide references for the basic research on the treatment of lumbar intervertebral disc degeneration by Chinese medicine. A summary shows that commonly used herbal compound prescriptions include both classical prescriptions such as Duhuo Jisheng Decoction, as well as clinical experience prescriptions such as Yiqi Huoxue Recipe. Angelicae Sinensis Radix, Chuanxiong Rhizoma, Rehmanniae Radix Praeparata, Achyranthis Bidentatae Radix, and Eucommiae Cortex were used most frequently. Tonic for deficiency and blood stasis activators were used most frequently. The most utilized monomeric components include icariin, ginsenoside Re, salvianolic acid B and aucubin. The main molecular mechanisms by which herbal compound and monomeric components delay of lumbar intervertebral disc degeneration include improving the intervertebral disc microenvironment, promoting the synthesis of aggregated proteoglycans and type Ⅱ collagen in the intervertebral disc, reducing the degradation of the extracellular matrix, and inhibiting apoptosis in the nucleus pulposus cells, etc. The main signaling pathways involved include Wnt/β-catenin signaling pathway, MAPK-related signaling pathway, mTOR signaling pathway, Fas/FasL signaling pathway, PI3 K/Akt signaling pathway, NF-κB signaling pathway, JAK/STAT signaling pathway, and hedgehog signaling pathway, etc.

ABSTRACT

Circular RNAs (circRNAs) are a type of endogenous non-coding RNAs discovered recently, which are produced by models such as circularization driven by intron pairing and are regulated by related regulatory factors. An important biological function of circRNAs is to act as a molecular sponge to make the level of microRNAs significantly change in a short period of time. A number of studies have shown that circRNAs are closely associated with ischemic stroke. Therefore, a better understanding of the function of circRNAs and its regulatory mechanism will help to explore the expression of circRNAs in early ischemic stroke and its molecular mechanism in the occurrence and development of ischemic stroke, so as to establish an early warning model to realize the early detection, early diagnosis and early treatment of ischemic stroke. This article reviews the definition, biological characteristics, and expression changes and roles of circRNAs after ischemic stroke.

ABSTRACT

Aim To investigate whether adiponectin is involved in the protective effect of sevoflurane preconditioning on myocardial ischemia/reperfusion (MI/R) injury. Methods C57 mice were randomly divided into four groups; the Sham Control (sham group), the MI/R-Control (model group), the MI/R-Sevopre (pretreatment group) and the APN-KO-MI/R-Sevopre (knockout pretreatment group). The plasma adiponectin level was detected 24 h after MI/R modeling. Meanwhile, the left ventricular end-systolic diameter, end-diastolic diameter and ejection fraction were measured at 24 h. In addition, TUNEL staining was used to detect the left ventricular end-systolic diameter, end-diastolic diameter and ejection fraction and the morphology and apoptosis of myocardial cells in each group were observed. What' s more, the infarct area was observed by Evans blue TTC staining. Results Compared with sham group, model group had impaired heart function, decreased ejection fraction and increased end-diastolic and end-systolic diameters. Meanwhile, the myocardial infarction area and apoptotic cells significantly increased in model group, and the plasma adiponectin level decreased. However, compared with model group, mice in sevoflurane pretreatment group had improved heart function, decreased myocardial infarction area, decreased apoptotic cells and increased plasma adiponectin levels. And then, compared with pretreatment group, sevoflurane pretreatment in knockout pretreatment group reduced Ml/R injury. Conclusion The sevoflurane pretreatment protects MI/R injury by increasing plasma adiponectin levels.

ABSTRACT

Weeds is one of the important parts of agricultural ecosystem of Chinese materia medica. Weeds is a double-edged sword with advantages and disadvantages for the cultivated medicinal plants. In this study, we firstly analyzed the positive and negative effects of weeds on the yield and quality of Chinese materia medica. We then explored the possible mechanisms for the weeds' positive effects from the aspects of interspecific relationship, soil microecological environment, light environment, natural control of pests and so on. We also summarized three basic principles of weed control, that is, "making medicinal plants and weeds coexist harmoniously, achieving the overall optimum growth of medicinal plants", "prevention first, integrated control" and "preserving beneficial weeds and increasing their beneficial effects, removing harmful weeds and control their adverse effects". Finally, we introduced several common weed ecological control technology in field of the cultivated medicinal plants in China, including technology of controlling weeds by no-tillage, stral mulch, rotation, alternative herbs, competitive crops, and allelopathy. This study is aimed to apply the ecology theory to guide weed management and control, so as to achieve the goal of advantages promotion and disadvantages elimination of weeds to cultivated medicinal plants, making weeds into treasure and to promote the sustainable and healthy development of Chinese medicinal materials production and the protection of weed diversity.

ABSTRACT

Ecological agriculture is a crucial way for agriculture of Chinese materia medica, which emphasizes the application of ecological principles in the cultivation of traditional Chinese medicine. While long-term intensive farming and modern chemical agriculture have threatened soil health, the sustainable development of ecological agriculture of Chinese materia medica is constrained. No-til-lage can reduce both frequency and intensity of tillage. Compared with conventional agriculture, no-tillage can reduce soil disturbance, maintain no-tillage for a long or permanent period and keep mulching. The application of no-tillage has a long history. More and more studies have shown that no-tillage has many advantages over conventional tillage, and the ecological and economic benefits of no-tillage are particularly outstandingin long-term. The cultivation of Chinese medicinal materials adheres to the principle of not grabbing land from farmland, making full use of the soil resources under forests, mountains and wasteland. Reducing the risk of soil loss and sustai-nable utilization are the core issues in the process of new land cultivation. No-tillage application, which not only inherits the traditional Chinese concept of natural farming, but also integrates the laws of ecological agriculture, will become the core strategies of sustainable development of Chinese materia medica ecological agriculture. This study will introduce the basic concepts and development process of no-tillage, analyze their ecological benefits in ecological agriculture of Chinese materia medica, and put forward their application strategies.

ABSTRACT

Among many factors that affect postmortem interval (PMI), temperature is undoubtedly the most important factor, but simply considering temperature in estimation of PMI has limitations. Accumulated degree days (ADD) is an important indicator related to biological growth and development, which considers two major variables, environmental temperature and elapsed time. Therefore, the establishment of mathematical model of ADD and some evaluation indicators to estimate PMI, is obviously better than single temperature variable. This article briefly describes the research history of ADD, its application in PMI estimation, and the problems it faces, to provide reference for the further development of ADD to improve the accuracy of PMI estimation.

ABSTRACT

Objective To determine the purine adenylate [adenosine triphosphate (ATP), adenosine diphosphate (ADP), adenosine monophosphate (AMP)] content in the muscles of both hind limbs of rats at different postmortem interval (PMI), calculate the changes in the total adenine nucleotide (TAN) content and the adenylic-acid energy charge (AEC), and explore their relationship with PMI. Methods Healthy rats were sacrificed by cervical dislocation and kept at 20 ℃. The muscles of their hind limbs were extracted at 0, 24, 48, 72, 96, 120, 144, and 168 h after death. Reversed-phase high performance liquid chromatography was used to determine the content of purine adenylates, the TAN and AEC of the muscles of the both hind limbs were calculated, and the related regression equations of their relationship with PMI were established. Results Within 168 h of death of rats, the trend of ATP change was different from ADP, and the content of AMP continuously increased. The TAN value gradually increased with the extension of PMI, and the AEC showed a downward trend within 168 h after death. Among them, the patterns of AEC changes with PMI were obvious, the correlation coefficient was high ( R2=0.903), and the curve fitting relationship was good; the fitting relationship between ATP, ADP, AMP, TAN and PMI was poor ( R2=0.198-0.754). Conclusion The postmortem change patterns of AEC provide new research ideas for PMI estimation in the forensic field.

ABSTRACT

To evaluate the clinical efficacy and safety of Shentong Zhuyu Decoction in the treatment of lumbar disc herniation, in order to provide evidence for its clinical application. PubMed, Cochrane Library, EMbase, CNKI, WanFang, VIP, CBM and Clinical Trials.gov databases were sysmatically retrieved. Two researchers independently searched, screened and extracted data. Randomized controlled trials in line with the inclusion criteria were included in the study. The article quality was assessed with the bias risk tool in the Cochrane Handbook. Meta-analysis was performed using RevMan 5.3. A total of 604 articles were obtained from the retrieval, and 824 patients in 9 studies were finally selected through screening. The course of treatment was about 1 month, and all of the studies were completed in China. Meta-analysis showed that the efficacy of Shentong Zhuyu Decoction in the treatment of lumbar disc herniation was better than that of the control group(RR=1.19, 95%CI[1.12, 1.26], P<0.000 01), including the comparison with Yaotongning Capsules(RR=1.10, 95%CI[1.02, 1.19], P=0.01) and diclofenac sodium tablets(RR=1.26, 95%CI[1.11, 1.44], P=0.000 4). In VAS pain score, Shentong Zhuyu Decoction had also obvious advantages(MD=-3.70, 95%CI[-6.31,-1.09], P=0.005). In addition, the number of adverse events in the Shentong Zhuyu Decoction group was lower than that in the control group. Shentong Zhuyu Decoction can effectively alleviate discomfort symptoms of patients with LDH. It has an obvious clinical efficacy and less adverse reactions. However, restricted by the quality of the included literatures, prospective, multi-center, large-sample-size randomized controlled trials are still needed to further improve the clinical evidence of the effect of Shentong Zhuyu Decoction in the treatment of LDH.

ABSTRACT

It is of great significance to carry out scientific investigation of threatened species and assess their in-situ conservation status in order to guide the conservation and management of these species within a region. In this study, we explored and assessed the biodiversity and in-situ conservation status of the threatened medicinal vascular plants(TMVPs) in central China. The results showed that there were 276 TMVPs in central China, including 18 critically endangered(CR), 77 endangered(EN), and 181 vulnerable(VU) species. Of which, 222 TMVPs were distributed in 49 national nature reserves, with an in-situ conservation rate of 80.43%. And the in-situ conservation rate of CR, EN and NR species were 83.33%, 77.92% and 81.22%, respectively. The complementary algorithm was used to select the nine national nature reserves with the highest protection and complementary contribution to the TMVPs. The cumulative protection contribution rate of these nine nature reserves was 81.98%. Fifty-four TMVPs were distributed outside of national nature reserves, while mainly distributed within 10 hotspot counties including Badong county, Hubei province, Sangzhi county, Hunan province, Jianghua Yao Autonomous county, Hunan province and so on. In general, TMVPs are well protected by the national nature reserves in central China. However, there are still some conservation gaps. It is necessary to carry out further field investigation on the species with conservation gaps and identify the gap areas, so as to provide scientific guidance for the optimization of the conservation of TMVPs in this region.
