Adropin attenuates pancreatitis­associated lung injury through PPARγ phosphorylation­related macrophage polarization.

Acute pancreatitis (AP)­associated lung injury (ALI) is a critical complication of AP. Adropin is a regulatory protein of immune metabolism. The present study aimed to explore the immunomodulatory effects of adropin on AP­ALI. For this purpose, serum samples of patients with AP were collected and the expression levels of serum adropin were detected using ELISA. Animal models of AP and adropin knockout (Adro­KO) were constructed, and adropin expression in serum and lung tissues was investigated. The levels of fibrosis and apoptosis were evaluated using hematoxylin and eosin staining, Masson's staining and immunohistochemistry of in lung tissue. M1/M2 type macrophages in the lungs were detected using immunofluorescence staining, western blot analysis and reverse transcription­quantitative PCR. As shown by the results, adropin expression was decreased in AP. In the Adro­KO + L­arginine (L­Arg) group, macrophage infiltration, fibrosis and apoptosis were increased. The expression of peroxisome proliferator­ activated receptor γ (PPARγ) was downregulated, and the macrophages exhibited a trend towards M1 polarization in the Adro­KO + L­Arg group. Adropin exogenous supplement attenuated the levels of fibrosis and apoptosis in the model of AP. Adropin exogenous supplement also increased PPARγ expression by the regulation of the phosphorylation levels, which was associated with M2 macrophage polarization. On the whole, the findings of the present study suggest that adropin promotes the M2 polarization of lung macrophages and reduces the severity of AP­ALI by regulating the function of PPARγ through the regulation of its phosphorylation level.

[Germplasm resource evaluation of Chrysanthemi Indici Flos based on color and chemical components].

This study explored the correlation between color and chemical components of Chrysanthemi Indici Flos(CIF), aiming at providing a reference for its procurement, evaluation, and breeding. Colorimeter and ultra-performance liquid chromatograph(UPLC) were used to determine the color(lightness-shade chromaticity value L~*, red-green chromaticity value a~*, yellow-blue chromati-city value b~*) and chemical components(cynaroside, linarin, luteolin, apigenin, and chlorogenic acid) of 84 CIF germplasms, respectively. Diversity analysis, correlation analysis, regression analysis, and cluster analysis were performed. The results showed that the color and chemical components of CIF were diversified. Chlorogenic acid was in significantly positive correlation with L~* and b~* and significantly negative correlation with a~*. Cynaroside and grey relational grade γ_i of chemical components were in significantly po-sitive correlation with b~* and L~*, respectively, whereas linarin, luteolin, and apigenin had no significant correlation with L~*, a~*, or b~*. The 84 CIF germplasms were clustered into 4 clades. In addition, germplasms in clade Ⅲ had higher γ_i and total color value(E~*_(ab)) than those in other clades, with the best quality and color, and a germplasm with the highest quality, bright yellow color, and highest content of linarin was screened out in this clade. Thus, CIF with bright yellow color had high content of cymaroside and chlorogenic acid and thereby high quality. In summary, the color can be used to quickly predict the quality of CIF. Our results provided data for the evaluation of CIF quality by color and a reference for its procurement and breeding.

Clinical observation and risk assessment after splenectomy in hepatolenticular degeneration patients associated with hypersplenism.

Background: Both hepatolenticular degeneration (HLD) and viral hepatitis B (HBV) can cause hypersplenism, but whether splenectomy is needed or can be performed in HLD patients associated with hypersplenism is still controversial. At present, HLD combined with hypersplenism has not been listed as the indication of splenectomy. Objective: This study aimed to investigate the efficacy, risks, and postoperative complications of splenectomy in HLD patients associated with hypersplenism. Methods: We retrospectively analyzed the clinical data of 180 HLD patients with hypersplenism who underwent splenectomy in the Department of General Surgery, First Affiliated Hospital of Anhui University of Traditional Chinese Medicine, from January 2001 to December 2015. To evaluate the efficacy of splenectomy, the hemogram of white blood cells (WBC), red blood cells (RBC), platelets (PLT), and the liver function indexes including alanine aminotransferase, aspartate aminotransferase, and total bilirubin were recorded before surgery and 1, 3, 5, 7, and 14 days after surgery. In addition, the clinical data of 142 HBV patients with hypersplenism who underwent splenectomy over the same period were also recorded and compared with that of HLD patients. In particular, aiming to assess the risks of splenectomy in HLD, we also compared postoperative complications and 36-month mortality between the two groups. Result: The level of WBC, RBC, and PLT were all elevated after splenectomy in both the HLD group and the HBV group. However, there was no significant difference in the variation of hemogram after splenectomy between the two groups (P > 0.05). Similarly, the variation of liver function indexes showed no statistical difference between the two groups. In terms of the incidence of postoperative complications including abdominal bleeding, pancreatic leakage, portal vein thrombosis treatment, incision infection, lung infection, and 36-month mortality, there were no significant differences between the two groups. Conclusion: After splenectomy, the hemogram as well as liver function in the HLD group improved a lot and showed a consistent tendency with that in the HBV group. Meanwhile, compared to the HBV group, there was no significant difference in the incidence of postoperative complications in the HLD group. All these results indicate that splenectomy in HLD patients combined with hypersplenism is completely feasible and effective.

Development and Validation of a Clinical Prediction Model for Complicated Appendicitis in the Elderly.

Background: For elderly patients with mild clinical symptoms of uncomplicated appendicitis(UA), non-surgical treatment has been shown to be feasible, whereas emergency surgical treatment is recommended in elderly patients with complicated appendicitis(CA), but it is still challenging to accurately distinguish CA and UA before treatment. This study aimed to develop a predictive model to assist clinicians to quickly determine the type of acute appendicitis. Methods: We retrospectively studied the clinical data of elderly patients with acute appendicitis who visited the First Affiliated Hospital of Anhui University of Traditional Chinese Medicine from January 2012 to January 2022. The patients were divided into UA group and CA group, and the general conditions, medical history, physical examination, laboratory examination and imaging examination were compared between the two groups, and SPSS 26.0 and R 4.0.2 software were used to establish CA clinic. Predict the model, and validate it internally. Results: The clinical data of 441 elderly patients with acute appendicitis were collected, 119 patients were excluded due to incomplete clinical data or other diseases. Finally, 332 patients were included in the study and divided into UA group (n = 229) and CA group (n = 103). By analyzing the clinical data of the two groups of patients, the duration of abdominal pain [OR = 1.094, 95% CI (1.056-1.134)], peritonitis [OR = 8.486, 95% CI (2.017-35.703))] and total bilirubin [OR = 1.987, 95% CI (1.627-2.426)] were independent predictors of CA (all p < 0.01). The model's Area Under Curve(AUC) = 0.985 (95% CI, 0.975-0.994). After internal verification by Bootstrap method, the model still has high discriminative ability (AUC = 0.983), and its predicted CA curve is still in good agreement with the actual clinical CA curve. Conclusion: We found that a clinical prediction model based on abdominal pain duration, peritonitis, and total bilirubin can help clinicians quickly and effectively identify UA or CA before treatment of acute appendicitis in the elderly, so as to make more scientific clinical decisions.

Conjugated linoleic acid ameliorates hepatic steatosis by modulating intestinal permeability and gut microbiota in ob/ob mice.

Background: Conjugated linoleic acid (CLA) is an effective supplement for reducing fat mass, but its effect on hepatic steatosis remains controversial. Objective: This study aims to evaluate the effect of CLA on liver fat accumulation, inflammation, gut microbiome, and intestinal barrier integrity. Design: Wild-type (WT) mice and ob/ob (OB) mice were randomly divided into four groups according to the treatment with/without 1% CLA: WT, WT mice treated with CLA (WT-CLA), OB, and OB mice treated with CLA (OB-CLA). Lipid metabolism and hepatic fat accumulation were evaluated by changes in histological and biochemical parameters. Gene expressions related to liver inflammation and intestinal barrier integrity were examined. The effect of CLA on the gut microbiota population was investigated. Results: The body weight, fatty tissue mass, and serum lipid levels of the WT-CLA group and OB-CLA group were separately lower than those of the WT group and OB group, but the livers of the WT-CLA group had more fatty lipids, higher triglyceride properties, and saturated fatty acid (FA) composition than those of the WT group, which was contrary to the effect of CLA on OB mice. Real time quantitative PCR results showed that CLA increased hepatic inflammation and intestinal permeability in the WT mice, while it significantly decreased the mRNA expression of liver TNF-α, IFN-γ, and IL-1ß and markedly ameliorated intestinal tight junction proteins in the OB mice. The gut microbiota testing indicated a higher abundance of beneficial bacteria (e.g., Lachnoclostridium, Roseburia, Dubosiella, Oscillibacter, and Anaerostipes) and a lower abundance of pro-inflammatory bacteria (e.g., Tyzzerella and Alistipes) in the OB-CLA group than those of the OB group. Correlation analysis suggested that gut microbiota correlated with liver inflammation, intestinal permeability, and hepatic FA composition. Conclusion: CLA potentially contributed to ameliorating hepatic steatosis in OB mice via modulating liver inflammation, intestinal permeability, and gut microbiota, which suggests CLA is more suitable for people with obesity or overweight.

[Electroacupuncture pretreatment alleviates apoptosis of renal tubular epithelia cells by down-regulating expression of TRPC6 in hyperglycemic mice].

OBJECTIVE: To observe the effect of electroacupuncture (EA) pretreatment on apoptosis of renal tubular epithelial cells in mice with hyperglycemia, so as to explore its mechanisms underlying protecting the kidney from hyperglycemia-induced injury. METHODS: Eighty male C57BL/6 mice were equally and randomly divided into control, model, EA and sham EA groups. The hyperglycemia model was established by intraperitoneal injection of streptozocin (STZ, 50 mg·kg-1·d-1) for 5 consecutive days. Before modeling, EA (2 Hz/15 Hz, 0.3-0.5 mA) was applied to bilateral "Zusanli" (ST36) and "Shenshu" (BL23) for 30 min, once daily for 7 days, while mice in the sham EA group were treated with the same acupoints but without electrical stimulation. The blood glucose values were measured after fasting for 6 hours after 3 days of modeling. The degree of renal tissue injury was observed by microscope after H.E. staining, and the apoptosis level of renal tubular epithelial cells observed by TUNEL staining. The expression levels of transient receptor potential channel 6 (TRPC6) and related apoptotic proteins Caspase-3, Bax and Bcl-2 in the renal tissue were detected by Western blot and immunohistochemistry, separately. RESULTS: Compared with the control group, the blood glucose content and the expression levels of TRPC6, Caspase-3 and Bax proteins, as well as the level of the renal apoptotic cells were significantly increased (P<0.001, P<0.000 1), while the expression level of Bcl-2 protein and the ratio of Bcl-2/Bax were remarkably decreased in the model group (P<0.000 1). In comparison with the model and sham EA groups, the blood glucose content, percentage of apoptotic cells and the expression levels of TRPC6, Caspase-3 and Bax were significantly decreased (P<0.01, P<0.000 1, P<0.05, P<0.001), and the expression level of Bcl-2 and the ratio of Bcl-2/Bax were apparently increased in the EA group (P<0.01, P<0.05, P<0.001). HE statin showed abnormal dilation of the capillary lumen and disappearance of the proximal tubules in the model group, which was relatively milder in the EA group. CONCLUSION: EA pretreatment can lower blood glucose level and reduce renal apoptosis in hyperglycemia mice, which may be related to its effects in down-regulating the expression of TRPC6 and Caspase-3 and up-regulating the ratio of Bcl-2/Bax.

Total Ginsenoside Extract from Panax ginseng Enhances Neural Stem Cell Proliferation and Neuronal Differentiation by Inactivating GSK-3β / 中国结合医学杂志

OBJECTIVE@#To study the effects of total ginsenosides (TG) extract from Panax ginseng on neural stem cell (NSC) proliferation and differentiation and their underlying mechanisms.@*METHODS@#The migration of NSCs after treatment with various concentrations of TG extract (50, 100, or 200 µ g/mL) were monitored. The proliferation of NSCs was examined by a combination of cell counting kit-8 and neurosphere assays. NSC differentiation mediated by TG extract was evaluated by Western blotting and immunofluorescence staining to monitor the expression of nestin and microtubule associated protein 2 (MAP2). The GSK-3β/β-catenin pathway in TG-treated NSCs was examined by Western blot assay. The NSCs with constitutively active GSK-3β mutant were made by adenovirus-mediated gene transfection, then the proliferation and differentiation of NSCs mediated by TG were further verified.@*RESULTS@#TG treatment significantly enhanced NSC migration (P<0.01 or P<0.05) and increased the proliferation of NSCs (P<0.01 or P<0.05). TG mediation also significantly upregulated MAP2 expression but downregulated nestin expression (P<0.01 or P<0.05). TG extract also significantly induced GSK-3β phosphorylation at Ser9, leading to GSK-3β inactivation and, consequently, the activation of the GSK-3β/β-catenin pathway (P<0.01 or P<0.05). In addition, constitutive activation of GSK-3β in NSCs by the transfection of GSK-3β S9A mutant was found to significantly suppress TG-mediated NSC proliferation and differentiation (P<0.01 or P<0.05).@*CONCLUSION@#TG promoted NSC proliferation and neuronal differentiation by inactivating GSK-3β.

Comparison of Murraya exotica and Murraya paniculata by fingerprint analysis coupled with chemometrics and network pharmacology methods.

There are two source plants for the traditional Chinese medicine Murrayae Folium et Cacumen (MFC) in Chinese Pharmacopoeia, i.e. Murraya exotica L. and M. paniculata (L.) Jack. Herein, a chemical comparison of M. exotica and M. paniculata by high performance liquid chromatography (HPLC) fingerprint analysis coupled with chemometrics and network pharmacology was performed. The main peaks in the fingerprints were identified by liquid chromatography coupled with ion trap/time-of-flight mass spectrometry (LC-IT-TOF-MS) and authenticated by references. The chemometrics results showed that the HPLC fingerprints of these two species were clearly divided into two categories using hierarchical cluster analysis (HCA) and principal component analysis (PCA), and a total of 13 significantly differentiated markers were screened out by orthogonal partial least squares-discriminant analysis (OPLS-DA). However, the following network pharmacology analysis showed that these discriminated markers were found to act via many common targets and metabolic pathways, indicating the possibly similar pharmacological effects and mechanisms for M. exotica and M. paniculata. The above results provide valuable evidence for the equivalent use of these two plants in clinical settings. Moreover, the chromatographic fingerprint analysis coupled with chemometrics and network pharmacology supplies an efficient approach for the comparative analysis of multi-source TCMs like MFC.

[Correlations between content of linarin in Chrysanthemum indicum and climatic factors in habitats].

Chrysanthemi Indici Flos(CIF), the capitulum of Chrysanthemum indicum, is widely used in proprietary Chinese medicine and daily chemical products. At present, CIF is mainly produced from wild resources and rarely cultivated. This study aims to reveal the correlations between linarin content in CIF and climatic factors in different habitats, and provide a theoretical basis for suitable zoning and rational production of medicinal materials. The content of linarin in CIF was determined by HPLC. Grey relational analysis and Pearson correlation analysis were carried out for linarin content with climatic factors. The results showed that the content of linarin in CIF was significantly different among different habitats. The grey relational degrees of climatic factors with linarin content was in an order of average annual precipitation>annual average sunshine hours>annual average temperature>longitude>annual frost-free period>latitude>altitude. Longitude, annual average temperature and average annual precipitation had significantly positive correlations with the content of linarin in CIF, whereas latitude and altitude showed negative correlations with it. The annual frost-free period and annual average sunshine hours had no significant correlation with the content of linarin in CIF. The content of linarin in CIF varied significantly in different habitats. High longitude, low latitude, low altitude, high annual average temperature and high annual average precipitation could be used as indicators for the habitats of high-quality Ch. indicum. This study provides a reference for selecting suitable producing areas of Ch. indicum and establishing artificial cultivation system.

Mechanism of Traditional Chinese Medicine in Treatment of Autism Spectrum Disorder Based on Heart and Spleen / 中国实验方剂学杂志

Autism spectrum disorder （ASD） is a common neurodevelopmental disorder in childhood， whereas there is no specific medicine at present. There are more and more researches on the treatment of ASD with traditional Chinese medicine（TCM） which the curative effect is reliable. The heart and spleen are the main viscera for the treatment of ASD， but there is still a lack of in-depth analysis of the mechanism of TCM. In order to explore the relationship between the core symptoms of ASD and the heart and spleen， this article specifically explores the theoretical origins of the heart and the spleen in the formation of the core symptoms of ASD， and to clarify the role of the heart and spleen in the occurrence and development of the two core symptoms of ASD from the perspective of TCM. In view of social communication and communication obstacles， the author puts forward and explains the language problems of children with ASD based on the functions of the heart and spleen， the theory of the viscera， the ascription of the meridians， and the classics. The mechanism of the heart and spleen in TCM about the failure of the spleen， the loss of the heart， and the endogenous phlegm. Aiming at the mechanism of the stereotyped symptoms of abnormal behaviors in children with ASD， this paper proposes and explains the TCM mechanism of constant deficiency of the spleen and dereliction of duty， leading to loss of mind， heart and spleen injury， and finally a series of stereotypes and strange syndromes due to lack of spirit. Through the analysis and excavation of TCM theory， it explores theoretical basis for ASD from the theory of heart and spleen， with a view to preliminarily constructing the theoretical framework of TCM syndrome differentiation and treatment of the deficiency of both the heart and spleen， and provide theoretical reference for TCM syndrome differentiation and treatment of ASD. The treatment of ASD from the differentiation of symptoms and signs of the heart and spleen is supported by a strong theoretical basis of TCM， and the rationale， law and prescriptions are complete， which may be the direction of screening effective TCM prescriptions for the treatment of ASD in the future.

Overview of systematic reviews on Shenmai Injection in prevention and treatment of diseases / 中国中药杂志

To summarize and evaluate the efficacy and safety of Shenmai Injection in the treatment of viral myocarditis, shock, pulmonary heart disease, coronary heart disease, neutropenia and tumor chemotherapy, so as to provide supportive evidences for clinical rational use of Shenmai Injection. By searching literatures about studies on the systematic reviews on Shenmai Injection in treatment of viral myocarditis, shock, pulmonary heart disease, coronary heart disease, neutropenia and tumor chemotherapy from the main Chinese and English databases. Primary efficacy and safety outcome measures were selected for comparative analysis and summary, and the appraisal tool of AMSTAR 2 was used to evaluate the included studies.A total of 36 systematic reviews(published from 2005 to 2020) were included, involving viral myocarditis, shock, pulmonary heart disease, malignant tumor and coronary heart disease. The number of cases included in each type of the above diseases was 3 840, 2 484, 12 702, 28 036 and 27 082, respectively. The comparison results showed that, Shenmai Injection combined with conventional/western medicine treatment groups had better efficacy than conventional/western medicine groups alone in the prevention and treatment of the above five diseases. The main adverse reactions of Shenmai Injection reported in the included studies were facial flushing, rash, palpitation, etc., but the incidence was low and the general symptoms were mild, so no special treatment was needed. Therefore, the application of Shenmai Injection on the basis of conventional treatment or western medicine treatment had better prevention and treatment efficacy of the diseases. It was suggested that more multi-center and larger sample-size randomized controlled trials should be carried out in the future, and the relevant reporting standards should be strictly followed in systematic reviews, so as to improve the scientificity and transparency of the study.

It has the pharmacological effects of protecting liver, anti-tumor, anti-fibrosis, anti-oxidation, inhibiting lipid accumulation and immunosuppression. Because of its remarkable effect of reducing enzymes and protecting the liver, it is mainly used for the treatment of various types of hepatitis in clinical application. The flavonoids, megastigmanes, alkaloids, sterols, triterpenes and other chemical constituents in S. sarmentosum are the important material basis for its pharmacological action. In this paper, the research progress on the chemical constituents and pharmacological effects of S. sarmentosum were reviewed, and the research status and research direction of S. sarmentosum were analyzed, in order to provide a reference for its further rational development and application.

Anti-inflammatory chemical constituents of Flos Chrysanthemi Indici determined by UPLC-MS/MS integrated with network pharmacology.

Flos Chrysanthemi Indici (FCI), the flower of Chrysanthemum indicum L., is a common functional food and a well-known traditional Chinese medicine (TCM) for the treatment of inflammatory diseases. Previous studies have revealed that FCI has anti-inflammatory activity, but little is known about its anti-inflammatory chemical profile. In this study, the potential anti-inflammatory constituents of FCI were investigated by ultra-high-performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry (UPLC-Q-TOF/MS) combined with the network pharmacology approach, and further confirmed on a LPS activated RAW264.7 macrophage model. As a result, a total of forty-two compounds, including thirty-two flavonoids, nine phenolic acids and one sesquiterpene, were identified. Among them, fourteen compounds including eight flavonoids (11, 17, 24, 28, 32, 39, 41 and 42) and six caffeoylquinic acids (3, 4, 5, 13, 15 and 20) were recognized as potential key anti-inflammatory constituents of FCI through network pharmacology analysis, because they accounted for 92% of the relative peak area in the UPLC-Q-TOF/MS chromatogram and acted on 87 of 97 the inflammatory targets of FCI. However, only 16 targets were shared between the flavonoids and caffeoylquinic acids, indicative of both acting on more different targets. Further the anti-inflammatory effects of the fourteen constituents were validated with the decreased levels of NO, TNF-α, IL-6 and PGE2 in RAW264.7 macrophage cells treated with LPS. Our results indicated that both flavonoids and caffeoylquinic acids were responsible for the anti-inflammatory effect of FCI through synergetic actions on multi-targets. Moreover, 3,5-dicaffeoylquinic acid (15), luteolin (24) and linarin (28) were the most important active constituents of FCI and could be selected as chemical markers for quality control of FCI. Overall, the findings not only explore the anti-inflammatory chemical constituents of FCI, but also provide novel insights into the effective constituents and mechanism of TCMs.

CONCLUSIONS: Qihuang decoction combined with enteral nutrition can promote the absorption of enteral nutrition with improving the immune and reducing complications of infection.

[Study on wild tending of Chrysanthemum indicum].

To provide theoretical basis for the formation of Chrysanthemum indicum resource and quality,the differences in biology,ecology,yield and quality of Ch. indicum population in the wild tending,the cultivated and the wild were analyzed and compared in this study. The results showed that in the aspect of biology,there was no significant difference between the condition of wild tending and cultivated Ch. indicum at the height of plant,both were significantly higher than wild Ch. indicum. In the aspect of ecology,in the condition of wild tending is less likely to occur water logging than cultivated Ch. indicum. In the condition of wild tending is less likely to occur plant diseases and insect pests than Ch. indicum in the condition of wild. In the aspect of production,the average output of the sample of the condition of wild tending was significantly higher than that the condition of artificial cultivation and wild quadrat. There was no significant difference between the three kinds of condition on the traits of capitulum dichasium,the content of buddleoside of the wild tending Ch. indicum was significantly higher than that of 0. 80% required by the Chinese Pharmacopoeia( 2015 edition). Therefore,the artificial supplement and the appropriate artificial management of wild tending is a mode of production to increase the population density of Ch. indicum and obtain high quality and high yield medicinal materials.

[Effect of Chrysanthemum indicum on absorption characteristics of Cd and its effect on quality of medicinal materials].

The Cd stress of Chrysanthemum indicum was treated by different concentrations of Cd Cl2 solution in the culture substrate. The content of Cd in different parts of Ch. indicum and the content of buddleoside and the total flavonoids in Ch. indicum were determined. The absorption characteristics of Cd elements in Ch. indicum were analyzed. And the influence of Cd elements on the quality of the herbs. The results showed that the application of soil Cd in the range of 0-100 mg·kg~(-1) had no significant effect on the biomass of Ch. indicum,and the root-shoot ratio showed a decreasing-increasing-decreasing trend. The content of Cd in different parts of Ch. indicum was significantly different,and the content of aboveground part was higher than that of underground part. The enrichment factors of Cd elements in different parts of Ch. indicum are different. The enrichment coefficient of aboveground parts is larger than that of underground parts. The whole parts and plants show an increase first and then decrease,and the overall enrichment factor is greater than1. The transfer coefficient of the aerial part/underground part of Ch. indicum showed a decreasing-increasing-decreasing-increasing trend with the increase of the amount of Cd applied in the soil,and the transfer coefficient was higher than 1. The contents of buddleoside and total flavonoids in Ch. indicum after Cd stress treatment were lower than the control,and the overall performance was lower and then increased,but it was still significantly lower than the control,indicating that Cd pollution directly led to the decrease of chemical quality of Ch. indicum.

Discussion on Research and Development of Following Original Methods of Famous Classical Formulas——Taking Xiebaisan as an Example / 中国实验方剂学杂志

The National Medical Products Administration intends to simplify the registration and approval process of the classic Chinese herbal compound preparations that meet the requirements, but it is a prerequisite for obtaining preferential policies that the preparation method and the route of administration are consistent with the records of ancient medical books. As most of the famous classical formulas are recorded in the medical books of the Qing dynasty and before the Qing dynasty, during the use of medicinal materials in various dynasties, the processing of herbs, dose of medicinal herbs, and the method of decocting may have changed. If researchers simply adopt modern methods to study the formula, it is easy to deviate from policy requirements. The strengthening of preliminary data survey and definition of prescription component and the medication situation of the dynasties can provide strong theoretical support for the study of famous classical formulas. Based on this, the authors take Xiebaisan as an example, which being collected in the First Batch of Catalogue of Ancient Classical Formulas. By following the principles of ancient methods, the research and development ideas of the classic Chinese herbal compound preparations were expounded from the aspects of origin of medicinal materials, processing of medicinal materials, preparation of standard decoction and quality standard of Xiebaisan granules, so as to provide a referential method for the development and research of the famous classical formulas.

[Phenolic constituents from stems of Ilex asprella].

Phytochemical investigation on Ilex asprella stems by using various chromatographic techniques led to the isolation of 18 phenolic constituents. Based on spectroscopic data analyses and/or comparison of the spectroscopic data with those in literature, these constituents were identified, including two lignans (1, 2), five phenylpropanes (3-7), six chlorogenic analogues (8-13), and five benzoic analogues (14-18). Among them, compounds 3-7, 9, 11, 13, 14, 17, and 18 were isolated from genus Ilex for the first time, and 2, 8, 10, 15, and 16 were isolated from this species for the first time. The in vitro anti-inflammatory assay results showed that compounds 8, 9, 11, 13, and 15 possessed moderate inhibition on the NO production in RAW264.7 cells with IC50 values of 51.1-85.8 µmol·L⁻¹. The present study brought preliminary reference for the clarification of therapeutic ingredients of I. asprella with anti-inflammatory efficacy and its quality evaluation.

[Comparative study on content of heavy metals in Chrysanthemum indicum and soil in different areas].

ICP-MS was used to determine the contents of five heavy metals such as lead (Pb), cadmium (Cd), mercury (Hg), arsenic (As) and copper (Cu) in Chrysanthemum indicum and soil samples. Pearson correlation and path analysis were used to analyze the effects of latitude and longitude and altitude on the content of heavy metal elements in Ch. indicum. To explore the relationship between geographical location of heavy metal content in Ch. indicum and the content of heavy metal elements in soil. The results showed that the Ch. indicum had high enrichment of Cd and had a synergistic effect on the absorption of five heavy metal elements. Elevation directly affected the accumulation of Pb and Cd in Ch. indicum and was a positive effect. The direct positive effect of latitude acts on the accumulation of Hg and Cu in Ch. indicum. The effect of longitude on the Cd content was the negative effect of longitude. The geographical location had different effects on the accumulation of heavy metal elements in Ch. indicum. There was a certain interaction between direct and indirect effects. Ch. indicum had different absorption and enrichment characteristics for different heavy metal species. When controlling the heavy metal content and medicinal material quality of Ch. indicum, we must fully consider the influence of geographical location on the quality of medicinal materials, select suitable geographic regions to carry out acquisitions, and choose a good ecological environment. Regional establishment of Chinese herbal medicine planting bases, or adopting certain agricultural measures to reduce the absorption of heavy metal elements in Ch. indicum herbs, while conducting research on chemical composition, strengthening the research on the effective forms of heavy metals, and paying attention to the safety of medicinal herbs.
