ObjectiveTo investigate the mechanism of Baihuan Xiaoyao Decoction （Xiaoyaosan added with Lilii Bulbus and Albiziae Cortex） in alleviating depression-like behaviors of juvenile rats by regulating the polarization of microglia. MethodSixty juvenile SD rats were randomized into normal control， model， fluoxetine， and low-， medium-， and high-dose （5.36， 10.71， 21.42 g·kg-1， respectively） Baihuan Xiaoyao decoction groups. The rat model of juvenile depression was established by chronic unpredictable mild stress （CUMS）. The sucrose preference test （SPT） was carried out to examine the sucrose preference of rats. Forced swimming test （FST） was carried out to measure the immobility time of rats. The open field test （OFT） was conducted to measure the total distance， the central distance， the number of horizontal crossings， and the frequency of rearing. Morris water maze （MWM） was used to measure the escape latency and the number of crossing the platform. The immunofluorescence assay was employed to detect the expression of inducible nitric oxide synthase （iNOS， the polarization marker of M1 microglia） and CD206 （the polarization marker of M2 microglia）. Real-time polymerase chain reaction was employed to determine the mRNA levels of iNOS， CD206， pro-inflammatory cytokines ［tumor necrosis factor （TNF）-α， interleukin （IL）-1β， and IL-6］ and anti-inflammatory cytokines （IL-4 and IL-10） in the hippocampus. Western blotting was employed to determine the protein levels of iNOS and CD206 in the hippocampus. The levels of IL-4 and IL-6 in the hippocampus were detected by enzyme-linked immunosorbent assay. ResultCompared with the normal control group， the model rats showed a reduction in sucrose preference （P<0.05）， an increase in immobility time （P<0.05）， decreased motor and exploratory behaviors （P<0.05）， and weakened learning and spatial memory （P<0.05）. In addition， the model rats showed up-regulated mRNA and protein levels of iNOS and mRNA levels of IL-1β， IL-6， and TNF-α （P<0.05）. Compared with the model group， Baihuan Xiaoyao decoction increased the sucrose preference value （P<0.05）， shortened the immobility time （P<0.01）， increased the motor and exploratory behaviors （P<0.05）， and improved the learning and spatial memory （P<0.01）. Furthermore， the decoction down-regulated the positive expression and protein level of iNOS， lowered the levels of TNF-α， IL-1β， and IL-6 （P<0.01）， promoted the positive expression of CD206， and elevated the levels of IL-4 and IL-10 （P<0.01） in the hippocampus of the high dose group. Moreover， the high-dose Baihuan Xiaoyao decoction group had higher sucrose preference value （P<0.01）， shorter immobility time （P<0.01）， longer central distance （P<0.01）， stronger learning and spatial memory （P<0.01）， higher positive expression and protein level of iNOS （P<0.01）， lower levels of TNF-α， IL-1β， and IL-6 （P<0.05， P<0.01）， lower positive expression and mRNA level of iNOS （P<0.05）， and higher levels of IL-4 and IL-10 （P<0.05， P<0.01） than the fluoxetine group. ConclusionBaihuan Xiaoyao decoction can improve the depression-like behavior of juvenile rats by inhibiting the M1 polarization and promoting the M2 polarization of microglia in the hippocampus.

ObjectiveTo retrospectively analyze the effect of modified Shugan Dingji Decoction （疏肝定悸汤） on the occurrence of endpoint events in patients with paroxysmal atrial fibrillation of liver constraint and qi stagnation. MethodsA retrospective cohort study was conducted using the electronic medical record database of Longhua Hospital affiliated to Shanghai University of Traditional Chinese Medicine to screen and include patients with paroxysmal atrial fibrillation of liver constraint and qi stagnation from January 1st， 2018， to December 31th， 2021. The included patients were divided into an exposure group and a non-exposure group， each consisting of 100 cases， based on whether they received modified Shugan Dingji Decoction. General information of the patients including age， gender， body mass index， duration of illness and comorbidities， medication history， cardiac structure and function indicators such as left atrial diameter， left ventricular end-diastolic diameter， stroke volume and ejection fraction， and the occurrence of endpoint events assessed through 24-hour dynamic electrocardiography or electrocardiogram to determine the recurrence of paroxysmal atrial fibrillation were collected. Kaplan-Meier （K-M） curves and Log-Rank tests were used to conduct survival analysis on the occurrence of endpoint events in the two groups of patients. Univariate and multivariate Cox regression analyses were used to analyze the impact of various factors on entry into endpoint events. Additionally， a safety assessment was performed by comparing liver and kidney function indicators before and after treatment. ResultsIn the non-exposure group， a total of 49 cases （49.0%） experienced endpoint events， while in the exposure group， there were 26 cases （26.0%）. The Log-rank test indicated significant difference between the two groups （χ2=11.211， P=0.001）. Univariate Cox regression analysis showed that age， duration of illness， hypertension， diabetes， chronic heart failure， left atrial diameter， stroke volume， and the use of modified Shugan Dingji Decoction may be the influencing factors for the occurrence of endpoint events in patients with paroxysmal atrial fibrillation of liver constraint and qi stagnation （P＜0.05 or P＜0.01）. Multivariate Cox regression analysis showed that the risk of endpoint events in the exposure group was significantly lower than that in the non-exposure group （P＜0.01）. Patients with a duration of illness ＞12 months had a significantly higher risk of endpoint events compared to those with a duration of illness ≤12 months （P＜0.01）. Patients without concomitant hypertension had a lower risk of endpoint events compared to those with hypertension （P＜0.05）. Patients with left atrial diameter ＞40 mm had significantly higher risk of endpoint events than those with left atrial diameter ≤40 mm （P＜0.01）. There was no statistically significant difference in liver and kidney function indicators between the two groups before and after treatment （P＞0.05）. ConclusionThe use of modified Shugan Dingji Decoction is a protective factor for patients with paroxysmal atrial fibrillation of liver constraint and qi stagnation， which can help to reduce the recurrence and progression of atrial fibrillation. Long duration of illness， concomitant hypertension， and enlarged left atrial diameter are risk factors for patients to experience endpoint events.

Historical Evolution and Modern Research Progress of Processing of Scutellariae Radix / 中国实验方剂学杂志

By consulting ancient herbal books and modern literature， this paper systematically sorted out and researched the processing history， relevant processing norms in recent years， modern processing technology， chemical composition changes of processed products and their pharmacological mechanism of Scutellariae Radix， in order to provide a basis for the further development of Scutellariae Radix decoction pieces. According to the textual research of ancient books， there were many kinds of processing auxiliary materials of Scutellariae Radix， such as wine， vinegar， salt， honey， pig bile and so on， among which the wine processing was the most diverse and detailed， and the processed products such as raw products， stir-fried products， wine-processed products， fried charcoal products were still in use. The modern processing techniques of Scutellariae Radix mainly focus on the processing aspects of softening and slicing， wine processing and charcoal frying， and the research methods are relatively unified. At present， it is found that the changed chemical constituents of Scutellariae Radix after processing are flavonoids， polysaccharides， volatile oils and trace elements， etc. Pharmacological effects of processed products are hemostasis， antibacterial， anti-inflammatory， antioxidant， analgesic and antipyretic， treatment of lung diseases， treatment of colitis， etc. However， in the studies of Scutellariae Radix processing， there is a lack of research on the structural changes of chemical components caused by processing and a comprehensive comparative study on the pharmacological effects of various processed products. Based on this， it is suggested to carry out systematic research on the processing technology to processing mechanism， further explore the relationship between the change rule of material basis and pharmacological action before and after processing of Scutellariae Radix， and deepen the exploration of molecular mechanism and clinical application of processed products of Scutellariae Radix， in order to clarify the scientific connotation of the processing mechanism of Scutellariae Radix， and lay a foundation for the subsequent expansion of the application of Scutellariae Radix decoction pieces and the formulation of processing standards.

ObjectiveTo analyze the antidepressant quality markers（Q-Marker） of Bupleuri Radix（BP） before and after vinegar-processing by ultra-performance liquid chromatography-quadrupole-time-of-flight mass spectrometry（UPLC-Q-TOF-MS）， multivariate statistical analysis and network pharmacology. MethodUPLC-Q-TOF-MS was used to analyze the chemical basis of raw and vinegar-processed products of BP， and principal component analysis（PCA） orthogonal partial least squares-discriminant analysis（OPLS-DA） were used to identify the differential components in BP that changed significantly before and after vinegar-processing， which were regarded as candidate quality markers（Q-Marker）. Then the disease-drug-component-target network related to antidepressant effect of BP was constructed by network pharmacology， and the antidepressant Q-Marker of raw and vinegar-processed products of BP was determined. Rats were randomly divided into blank group， model group， fluoxetine group（2.67 mg·kg-1） and total saponin group（0.72 mg·kg-1）， except the blank group， rats in the other groups were subjected to chronic unpredictable mild stress（CUMS）. Three weeks after the start of modeling， rats in each administration group were given the corresponding dose of drugs once a day for 4 weeks， and rats in the blank and model groups were given normal saline with dose of 10 mL·kg-1. At 1 day before modeling， 21 days and 28 days after administration， body mass weighing， sucrose preference test and open field test were performed on each group . After 28 days of administration， real-time fluorescence quantitative polymerase chain reaction（Real-time PCR） was used to detect the mRNA expression levels of phosphatidylinositol 3-kinase（PI3K）， protein kinase B（Akt）， mammalian target of rapamycin（mTOR）， glycogen synthase kinase-3β（GSK-3β）， forkhead box transcription factor O3a（FoxO3a） and β-catenin in hippocampal tissues of rats in each group， while protein expression levels of PI3K， Akt， mTOR and FoxO3a in hippocampal tissues of rats in each group were detected by Western blot. ResultThere were 19 components in BP showed significant changes before and after vinegar-processing， and 9 components such as saikosaponin A， saikosaponin B1， saikosaponin B2， saikosaponin C and saikosaponin D were identified as potential Q-Marker through S-plot differential marker screening. Combined with the disease-drug-component-target network， saikosaponin A， saikosaponin B1， saikosaponin B2 and saikosaponin D were identified as antidepressant Q-Marker of raw and vinegar-processed products of BP. According to the results of pharmacodynamic tests， after 28 d of administration， compared with the blank group， the body mass， sucrose preference index and open field total score of rats in model group， fluoxetine group and total saponin group decreased significantly（P<0.01）. Compared with the model group， the body mass， sucrose preference index and open field total score in total saponin group increased significantly（P<0.01）. Compared with the blank group， mRNA expression levels of PI3K， Akt， mTOR and β-catenin in hippocampus of rats in the model group decreased significantly（P<0.05）， while mRNA expression levels of GSK-3β and FoxO3a increased significantly（P<0.05）. Compared with the model group， mRNA expression levels of PI3K， Akt， mTOR and β-catenin in hippocampus of rats in the total saponin group were increased significantly（P<0.05）， while mRNA expression levels of GSK-3β and FoxO3a decreased significantly（P<0.05）. Compared with the blank group， the protein expression levels of Akt and mTOR in hippocampus of the model group decreased significantly（P<0.01）， while the protein expression levels of PI3K and FoxO3a increased significantly（P<0.01）. Compared with the model group， the expression level of Akt in hippocampus of the total saponin group increased significantly（P<0.01）， the mTOR expression level was increased but not statistically significant， while the protein expression levels of PI3K and FoxO3a decreased significantly（P<0.01）. ConclusionThe chemical constituents of BP changed greatly after vinegar-processing， and the antidepressant Q-Marker of raw and vinegar-processed products of BP was determined by chemical basis， pharmacodynamics， network pharmacology and signaling pathway， which provided a reference for further research on quality control， pharmacodynamic substance basis and processing mechanism of BP.

ObjectiveTo explore the mechanism and pathway of Gandou Fumu decoction （GDFMD） in the development of liver fibrosis in Wilson's disease （WD）. MethodFirst， 30 TX-j mice were randomly divided into the model group， high-dose， medium-dose， and low-dose GDFMD groups， and penicillamine group， with six mice in each group， and another six wild-type mice were used as the normal group. The high-dose， medium-dose， and low-dose GDFMD groups were intragastrically administered drugs of 13.92， 6.96， 3.48 g·kg-1. In the penicillamine group， 0.1 g·kg-1 of penicillamine was given by intragastric administration. The model group and the normal group were given equal volume of normal saline， once a day， for four consecutive weeks. Samples were collected four weeks after gavage， and enzyme-linked immunosorbent assay （ELISA） was used to detect type Ⅲ procollagen peptide （PCⅢ）， collagen type Ⅳ （Col Ⅳ）， hyaluronic acid （HA）， and laminin （LN）. Hematoxylin-eosin （HE）， Masson， and picric acid-Sirus red collagen （Sirus Red） staining were used to observe the histopathological changes of liver fibrosis. Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR）， immunohistochemistry， and Western blot were used to observe the expressions of α-smooth muscle actin （α-SMA） and collagen type Ⅰ （Col Ⅰ）， which were related to the activation of hepatic stellate cells （HSCs）. The expression of miR-29b-3p was observed by Real-time PCR. The expression of Unc-51-like kinase 1 （ULK1） and its downstream-related factors were observed by Western blot. The downstream genes of miR-29b-3p were verified by the dual luciferase reporter gene detection method. ResultCompared with the normal group， the four items of liver fibrosis （PCⅢ， Col Ⅳ， HA， and LN） in the model group were significantly abnormal （P<0.01）， and the pathology was significantly abnormal. The expression of HSC activation-related indicators including α-SMA and Col Ⅰ， as well as α-SMA mRNA and Col Ⅰ mRNA was up-regulated （P<0.05， P<0.01）， and miR-29b-3p expression was down-regulated （P<0.01）. ULK1， p-ULK1， autophagy-related gene 13 （Atg13）， p-Atg13， Beclin-1， FAK family kinase-interacting protein of 200 kDa （FIP200）， activating molecule in BECN1-regulated autophagy protein 1 （AMBKA1）， and microtubule-associated protein 1 light chain 3Ⅱ/Ⅰ（LC3Ⅱ/Ⅰ） were up-regulated （P<0.05， P<0.01）. p62 protein expression was down-regulated （P<0.01）. Compared with the model group， the four items of liver fibrosis in the high-dose， medium-dose， and low-dose GDFMD groups and the penicillamine group were significantly improve （P<0.01）， and the pathological conditions were improved. The expression of HSC activation-related indicators including α-SMA and Col Ⅰ， as well as α-SMA mRNA and Col Ⅰ mRNA was down-regulated （P<0.05， P<0.01）， and the expression of miR-29b-3p was up-regulated （P<0.01）. ULK1， p-ULK1， Atg13， p-Atg13， Beclin-1， FIP200， AMBKA1， and LC3Ⅱ/Ⅰ were down-regulated （P<0.05， P<0.01）， and p62 protein expression was up-regulated （P<0.01）. The prediction software predicted that there was a binding site between miR-29b-3p and ULK1. The dual-luciferase reporter gene detection method indicated that the luciferase activity of the ULK1-WT plasmid-transfected cell group was reduced when miR-29b-3p mimics were co-cultured （P<0.01）. ConclusionGDFMD can regulate ULK1-mediated autophagy by up-regulating miR-29b-3p and further exert its anti-hepatic fibrosis effect in Wilson's disease.

Review and Prospect of Development Status of Traditional Chinese Medicine Processing Technology from 1.0 to 4.0 / 中国实验方剂学杂志

The development and application of processing technology is closely related to the quality of Chinese medicine. Currently， Chinese medicine processing is still in the mechanization stage with limited processing equipment， low levels of automation and intelligence. As a result， the imprecise control of parameters during processing leads to unstable quality of Chinese herbal pieces. However， with the arrival of the big data era and the continuous development of "Internet+"， Chinese medicine processing technology and equipment have been continuously improved and updated， and gradually shifted to the development direction of automation and intelligence. The linkage production technology of Chinese herbal pieces optimizes the separate processing equipment coupling into the production line for continuous manufacture of Chinese herbal pieces， intending to improve production efficiency. The large-scale industrialized production of Chinese herbal pieces tends towards digital technology of processing experience and online inspection technology based on machine vision， electronic nose， and electronic tongue. These technologies are crucial prerequisites for standardizing the parameters of Chinese medicine processing. And further by docking the processing process and equipment with the internet， realizing the intelligent control of the production process is an important process for the transformation and upgrading of Chinese herbal piece industry in the future. In this paper， we summarized the development characteristics of different stages of Chinese medicine processing technology， combed application and development of processing theory， the evolution of processing equipment， and problems in the current industrial development stage of Chinese medicine processing， in order to provide ideas and methods for achieving digital and intelligent innovation of processing technology as well as high-efficient and high-quality production of Chinese herbal pieces.

Protective Effects and Mechanisms of Huangqi Decoction Against Radiation-Induced Bystander Effects / Efectos Protectores y Mecanismos de la Decocción de Huangqi Contra los Efectos Secundarios Inducidos por la Radiación

SUMMARY: The 12C6+ heavy ion beam irradiation can cause bystander effects. The inflammatory cytokines, endocrine hormones and apoptotic proteins may be involved in 12C6+ irradiation-induced bystander effects. This study characterized the protective effects and mechanisms of Huangqi decoction (HQD) against 12C6+ radiation induced bystander effects. Wistar rats were randomly divided into control, 12C6+ heavy ion irradiation model, and high-dose/medium-dose/low-dose HQD groups. HE staining assessed the pathological changes of brain and kidney. Peripheral blood chemical indicators as well as inflammatory factors and endocrine hormones were detected. Apoptosis was measured with TUNEL. Proliferating cell nuclear antigen (PCNA) expression was determined with real-time PCR and Western blot.Irradiation induced pathological damage to the brain and kidney tissues. After irradiation, the numbers of white blood cells (WBC) and monocyte, and the expression of interleukin (IL)-2, corticotropin-releasing hormone (CRH) and PCNA decreased. The damage was accompanied by increased expression of IL-1β, IL-6, corticosterone (CORT) and adrenocorticotropic hormone (ACTH) as well as increased neuronal apoptosis. These effects were indicative of radiation-induced bystander effects. Administration of HQD attenuated the pathological damage to brain and kidney tissues, and increased the numbers of WBC, neutrophils, lymphocyte and monocytes, as well as the expression of IL-2, CRH and PCNA. It also decreased the expression of IL-1β, IL-6, CORT and ACTH as well as neuronal apoptosis. HQD exhibits protective effects against 12C6+ radiation-induced bystander effects. The underlying mechanism may involve the promotion of the production of peripheral blood cells, inhibition of inflammatory factors and apoptosis, and regulation of endocrine hormones.

La irradiación con haz de iones pesados 12C6+ puede provocar efectos secundarios. Las citoquinas inflamatorias, las hormonas endocrinas y las proteínas apoptóticas pueden estar involucradas en los efectos secundarios inducidos por la irradiación 12C6+. Este estudio caracterizó los efectos y mecanismos protectores de la decocción de Huangqi (HQD) contra los efectos externos inducidos por la radiación 12C6+. Las ratas Wistar se dividieron aleatoriamente en grupos control, modelo de irradiación de iones pesados 12C6+ y grupos de dosis alta/media/baja de HQD. La tinción con HE evaluó los cambios patológicos del cerebro y el riñón. Se detectaron indicadores químicos de sangre periférica, así como factores inflamatorios y hormonas endocrinas. La apoptosis se midió con TUNEL. La expresión del antígeno nuclear de células en proliferación (PCNA) se determinó mediante PCR en tiempo real y transferencia Western blot. La irradiación indujo daños patológicos en los tejidos cerebrales y renales. Después de la irradiación, disminuyó el número de glóbulos blancos (WBC) y monocitos, y la expresión de interleucina (IL)-2, hormona liberadora de corticotropina (CRH) y PCNA. El daño estuvo acompañado por una mayor expresión de IL-1β, IL-6, corticosterona (CORT) y hormona adrenocorticotrópica (ACTH), así como un aumento de la apoptosis neuronal. Estas alteraciones fueron indicativas de efectos inducidos por la radiación. La administración de HQD atenuó el daño patológico a los tejidos cerebrales y renales, y aumentó el número de leucocitos y monocitos, así como la expresión de IL-2, CRH y PCNA. También disminuyó la expresión de IL-1β, IL-6, CORT y ACTH, así como la apoptosis neuronal. HQD exhibe mecanismos protectores contra los efectos externos inducidos por la radiación 12C6+. El mecanismo subyacente puede implicar la promoción de la producción de células sanguíneas periféricas, la inhibición de factores inflamatorios y la apoptosis y la regulación de hormonas endocrinas.

After treatment， the observation group showed significantly better results in these indicators than the control group （P<0.05， P<0.01）. There was no statistically significant difference in thrombin time （TT） in the control group before and after treatment， while the observation group showed a significant prolongation after treatment （P<0.05）. There were no statistically significant differences in activated partial thromboplastin time （APTT） and prothrombin time （PT） between the two groups before treatment， and no serious adverse reactions occurred in either group. ConclusionFeining Paidu decoction combined with conventional treatment can alleviate inflammatory responses， improve hypercoagulable states， promote the absorption of pulmonary inflammation， and enhance the clinical efficacy of refractory Mycoplasma pneumoniae pneumonia in children.

Application of ZHANG Zhongjing，s Jizihuang （Egg Yolk） Prescriptions in Type 2 Diabetes Mellitus based on the Theory of “Yin Restricts Fire” and “Many Different Diseases can be Treated in the Same Way” / 中医杂志

Type 2 diabetes mellitus （T2DM） can be categorized into “xiao ke （消渴）” in traditional Chinese medicine （TCM）. The theory of “yin restricts fire” originates from Inner Canon of Yellow Emperor （《黄帝内经》） which states that “yin essence restricts chief fire”， and the crucial pathogenesis and treatment of xiao ke coincide with this theory. ZHANG Zhongjing，s three prescriptions of Jizizhuang （egg yolk） are Baihe Jizizi Decoction （百合鸡子汤）， Huanglian Ejiao Decoction （黄连阿胶汤） and Painong Powder （排脓散）， which are scattered in different chapters of Treatise on Cold Damage and Miscellaneous Diseases （《伤寒杂病论》）. By analyzing and summarizing the mechanism and characteristics of the three prescriptions， it is found that the three prescriptions are in line with the characteristics of “yin restricts fire” and the pathogenesis of T2DM. These three prescriptions are composed of Jizizhuang and different medicinals. Baihe Jizizi Decoction is composed of Jizizhuang and Baihe （Bulbus Lilii）， and can be used to treat T2DM and mental diseases. Huanglian Ejiao Decoction is composed of Jizihuang， Ejiao （Colla Corii Asini）， Shaoyao （Radix Paeoniae Alba seu Rubra）， Huanglian （Rhizoma Coptidis） and Huangqin （Radix Scutellariae）， which could be used to treat T2DM and cardiorenal system diseases. Painong Powder is composed of Jizizhuang， Shaoyao， Jiegeng （Radix Platycodonis） and Zhishi （Fructus Aurantii Immaturus）， which can be used to treat T2DM and carbuncle. Therefore， based on the theory of “yin restricts fire” and “many different diseases can be treated in the same wa”， this paper propose that the three Jizihuang prescriptions could be used in T2DM， which could provide ideas for clinical treatment.

Liver function indicators including alanine aminotransferase （ALT） and aspartate aminotransferase （AST）， and serum laminin （LN）， hyaluronic acid （HA）， pre-collagen type III （PCIII） and collagen type IV （CIV） were also detected. The protein expression of transforming growth factor β1 （TGF-β1）， Vimentin， E-cadherin， α smooth muscle actin （α-SMA） in liver tissue were detected. ResultsCompared to the blank group， the model group showed increased gray value， collagen deposition，serum ALT， AST， HA， LN and PCIII levels， decreased expression of E-cadherin， and increased expression of N-cadherin，α-SMA，Vimentin and TGF-β1 in liver tissues （P＜0.05）. Compared to the model group， the ultrasonic gray value and the proportion of collagen fiber deposition in liver of silybin group and YSJD medium- and high-dose groups decreased， and the serum ALT， AST， LN， HA and PCⅢ levels decreased. Compared to the model group， the expression of E-cadherin in liver tissues of silybin group and all three YSJD groups increased， while the expressions of N-cadherin， Vimentin， TGF-β1 and α-SMA decreased （P＜0.05）， and among them， most improvements were seen in the medium-dose YSJD group （P＜0.05）. ConclusionThe effect of YSJD on significantly reducing the extent of HF in mice caused by CCl4 may be related to its ability to regulate liver hardness and inhibit the occurrence of epithelial mesenchymal transition in mice.

Mechanism of Bielong Ruangan decoction in treatment of liver cancer based on network pharmacology and molecular docking / 中国医师杂志

Objective:To explore the key targets and mechanism of Bielong Ruangan decoction in the treatment of liver cancer based on network pharmacology and molecular docking.Methods:Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP) database, PubChem database and PharmMapper database were used to search and screen the chemical components and related targets of Bielong Ruangan decoction and the targets of liver cancer diseases. The network diagram of " Bielong Ruangan decoction-traditional Chinese medicine-active ingredient-predicted target-disease" was constructed; Protein-protein interaction (PPI) network were analyzed through String database; gene ontology (GO) enrichment analysis was performed through WebGestalt database; Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis was carried out through KEGG Orthology Based Annotation System (KOBAS) database; Molecular docking of the active components and core target proteins of Bielong Ruangan decoction was carried out by using PyMOL, Auto DockVina and other software.Results:Bielong Ruangan decoction had 67 active components, 154 liver cancer targets and 244 pathways. According to the analysis of network pharmacology, Bielong Ruangan decoction may play an anti-cancer role through key targets such as epidermal growth factor receptor (EGFR), mitogen activated protein kinase 1 (MAPK1), estrogen receptor 1 (ESR1), MAPK8, serine threonine protein kinase 1 (AKT1), MAPK14, cysteine protease 3 (CASP3), cyclin-dependent kinase 2 (CDK2), bone morphogenetic protein 2 (BMP2), aldose reductase (AKR1B1) and other key targets. KEGG enrichment analysis showed that the treatment of liver cancer by Bielong Ruangan decoction involved the regulation of vascular endothelial growth factor (VEGF) signaling pathway, tumor necrosis factor (TNF) signaling pathway, thyroid hormone signaling pathway, T cell receptor signaling pathway and other pathways. The results of molecular docking showed that the binding energy of all compounds to protein was less than -5.6 kcal/mol, indicating that each compound and each protein could bind well.Conclusions:Bielong Ruangan decoction participates in the treatment of liver cancer through " multi-component, multi-target and multi-channel" ways, and plays an anti-cancer role mainly by regulating the proliferation and invasion of tumor cells and tumor inflammatory microenvironment.

Effect of Liangxue Huoxue decoction on intestinal flora and NLRP3/caspase-1/GSDMD signaling pathway in mice model of sepsis-induced acute kidney injury / 中华危重病急救医学

Objective:To investigate the effect of Liangxue Huoxue decoction on intestinal flora, intestinal barrier and NOD-like receptor protein 3 (NLRP3)/caspase-1/gasdermin D (GSDMD) pyroptosis signaling pathway in mice model of sepsis-induced acute kidney injury (AKI).Methods:The model of AKI was established by cecal ligation and perforation (CLP). Thirty male C57BL/6 mice were randomly divided into sham operation group (Sham group), sepsis group (CLP group) and sepsis+Liangxue Huoxue decoction (CLP+LXHX group), with 10 mice in each group. Mice in Sham group only underwent laparotomy. Two hours before model establishment, mice in CLP+LXHX group were treated with Liangxue Huoxue decoction (6 g/kg) by gavage; mice in Sham group and CLP group were given equal volume of normal saline by gavages. After 24 hours of modeling, all mice were sacrificed under anesthesia, and the colon and kidney tissues and fresh feces in the colon were taken. The pathological changes of kidney and colon were observed by hematoxylin-eosin (HE) staining under light microscope. Real-time polymerase chain reaction (RT-PCR) was used to detect inflammatory factors (interleukins, IL-1β and IL-18) in renal tissue. The expressions of NLRP3, caspase-1 and GSDMD were detected by Western blotting. The changes of intestinal flora in mice were detected by 16S rDNA high-throughput sequencing.Results:Compared with the Sham group, the inflammatory cell infiltration of the kidney tissue was increased and the kidney became vacuolated in CLP group, the mRNA expressions of IL-1β, IL-18, and the protein expressions of NLRP3, caspase-1 and GSDMD were significantly increased in CLP group, the species richness of intestinal microflora decreased significantly, the relative abundance of Enterococcus and Escherichia-Shigella increased significantly, and the relative abundance of Ileibacterium, Alloprevotella, Lachnospiraceae, Klebsiella and Parasutterella increased significantly in CLP group. Compared with CLP group, Liangxue Huoxue decoction can significantly reduce the pathological changes of kidney and colon tissue, reduce the pathological score (1.75±0.43 vs. 3.50±0.50 for kidney tissue, 1.25±0.43 vs. 4.50±0.50 for colon tissue, both P < 0.05), improve the composition of intestinal flora, reduce the relative abundance of Enterococcus and Escherichia-Shigella, and significantly increase the relative abundance of Lactobacillus and Akkermansia. In addition, Liangxue Huoxue decoction can significantly reduce mRNA expressions of IL-1β and IL-18 in kidney tissue [IL-1β mRNA (2 -ΔΔCt): 1.59±0.05 vs. 4.61±0.88, IL-18 mRNA (2 -ΔΔCt): 1.69±0.17 vs. 2.86±0.63, both P < 0.05] and the protein expressions of NLRP3, caspase-1 and GSDMD (NLRP3/GAPDH: 0.71±0.04 vs. 0.89±0.01, caspase-1/GAPDH: 1.04±0.04 vs. 1.48±0.04, GSDMD/GAPDH: 0.90±0.01 vs. 1.41±0.02, all P < 0.05). Conclusions:Liangxue Huoxue decoction has obvious protective effect on AKI induced by sepsis. It can improve intestinal barrier by regulating intestinal flora, thereby inhibiting the activation of NLRP3/caspase-1/GSDMD signaling pathway in kidney tissue and reducing the expression of proptosis-related inflammatory factors.

Dachengqi decoction reduces inflammatory response and promotes recovery of gastrointestinal function in patients with mild acute pancreatitis by regulating the intestinal microbiota / 中华危重病急救医学

Objective:To explore the therapeutic effect and mechanism of Dachengqi decoction on patients with mild acute pancreatitis (MAP).Methods:A parallel randomized controlled trial was conducted. Sixty-eight patients with acute pancreatitis (AP) admitted to Shanghai Traditional Chinese Medicine (TCM)-Integrated Hospital from March 2018 to February 2021 were enrolled. Referring to the condition on admission of the patients and whether they agreed to receive the Dachengqi decoction or not, they were divided into conventional treatment group and Dachengqi decoction group according to the principle of 1∶1 equal randomness. Meanwhile, 20 healthy volunteers were recruited as controls. Both groups of patients were treated with octreotide, fasting, gastrointestinal decompression, antipyretic and analgesic, anti-inflammatory, inhibition of gastric acid and pancreatic juice secretion, maintenance of electrolyte balance and other western conventional medicine. The patients in the Dachengqi decoction group received Dachengqi decoction orally on the basis of routine treatment, 100 mL each time, twice a day, for seven consecutive days. The inflammation parameters [white blood cell count (WBC), C-reactive protein (CRP), procalcitonin (PCT), interleukin-6 (IL-6)] before and after treatment and the recovery time of gastrointestinal function (first exhaust time, time to recover bowel sounds, first defecation time) of patients were recorded. 16S rRNA gene sequencing of stool samples was recorded, and normalized data were obtained after quality control and other related processing. The data were subjected to diversity analysis (Alpha diversity and Beta diversity) and linear discriminant analysis effect size analysis (LEfSe analysis) to observe changes in the gut microbiota of MAP patients. Spearman rank correlation coefficient was used to analyze the correlation between inflammatory indexes and microorganisms at the intestinal genus level. Blood, urine, stool samples, renal function, and electrocardiogram (ECG) during treatment of MAP patients were detected to assess the safety of the treatment.Results:Of the 68 patients with AP, 16 were excluded from moderate-severe AP, 4 were not collected or voluntarily abandoned treatment. Finally, 48 patients with MAP were enrolled, 24 in the conventional treatment group and 24 in the Dachengqi decoction group. The inflammation parameters levels at 7 days of treatment in both groups were significantly lower than those before treatment. CRP, PCT and IL-6 levels in the Dachengqi decoction group were significantly lower than those in the conventional treatment group [CRP (mg/L): 8.50 (3.50, 13.00) vs. 16.00 (9.25, 29.75), PCT (μg/L): 0.06 (0.03, 0.08) vs. 0.09 (0.05, 0.11), IL-6 (ng/L): 6.36 (3.96, 10.79) vs. 13.24 (6.69, 18.87), all P < 0.05]. The first exhaust time, time to recover bowel sounds and first defecation time in the Dachengqi decoction group were significantly shorter than those in the conventional treatment group [first exhaust time (days): 1.62±0.65 vs. 2.80±0.65, time to recover bowel sounds (days): 1.13±0.58 vs. 2.31±0.76, first defecation time (days): 3.12±0.75 vs. 4.39±0.76, all P < 0.05]. The analysis of intestinal microflora diversity showed that both the diversity and abundance of microbial communities were the highest in the healthy control group and the lowest in the conventional treatment group. In addition, the coincidence degree of microbial communities in healthy controls and MAP patients was small, while the coincidence degree of MAP patients among different treatment methods was relatively large. LEfSe analysis showed that Dachengqi decoction reduced the relative abundance of Escherichia coli-Shigella and Clostridium erysipelae, and increased the relative abundance of three beneficial bacteria, namely Lactobacillus, Rombutzia and Brutella. In the intestines of MAP patients, Lactobacillus mucilaginus and Lactobacillus conjunctus were significantly enriched. Correlation analysis showed that positive correlations between Escherichia coli- Shigella and the four inflammatory indicators including WBC, CRP, PCT, IL-6 were statistically significant ( r value was 0.31, 0.41, 0.57, 0.43, respectively, all P < 0.05). There was no significant correlation between other bacteria and inflammatory indicators. During the treatment, there was no obvious abnormality in blood, urine and feces, renal function and ECG of MAP patients. Conclusions:Dachengqi decoction could reduce inflammatory responses and promote recovery of intestinal microecological balance and gastrointestinal function in patients with MAP by regulating the composition of intestinal flora. No significant adverse effects were observed during the treatment period.

Effects of modified Buzhong Yiqi Decoction on intestinal microflora in a rat model of chronic obstructive pulmonary disease / 中国基层医药

Objective:To investigate the effects of modified Buzhong Yiqi Decoction on intestinal microflora in a rat model of chronic obstructive pulmonary disease. Methods:From April to June 2021, 60 specific pathogen-free Wistar rats were selected for this study. They were randomly divided into blank control, model, traditional Chinese medicine, and western medicine groups with 15 rats per group. Rat models of chronic obstructive pulmonary disease with lung and spleen deficiency were established in all groups except the blank control group. Rat models in the traditional Chinese medicine and western medicine groups were administered modified Buzhong Yiqi Decoction and synbiotics. Rat models in the model and blank control groups were identically administered 0.9% sodium chloride injection. After 7 days, the feces of rats in each group were collected for 16S rRNA sequencing of intestinal flora. Effective sequences were clustered to obtain operational taxonomic units for principal coordinate analysis, species composition analysis, and alpha diversity analysis. The effects of modified Buzhong Yiqi Decoction on the structure, diversity, and abundance changes of intestinal flora were analyzed. Results:The dominant bacteria in the traditional Chinese medicine and western medicine groups were Firmicutes, while the dominant bacteria in the blank control and model groups were Bacteroides. The dominant bacterial groups in each group were mainly Lactobacillus and Bacteroides. Alpha diversity analysis showed that the Shannon index in the community diversity indices of traditional Chinese medicine, western medicine, and blank control groups was (3.65 ± 0.35), (3.65 ± 0.36), and (3.59 ± 0.20), respectively, which were significantly higher than (3.37 ± 0.26) in the model group ( t = 2.49, 2.44, 2.60, all P < 0.05). There was no significant difference in the Shannon index among traditional Chinese medicine, western medicine, and blank control groups (all P > 0.05). The Sobs index of the traditional Chinese medicine, western medicine, and blank control group was (458.67 ± 73.11), (454.80 ± 95.13), and (525.93 ± 101.88), respectively, which were significantly higher than (337.40 ± 37.49) in the model group ( t = 5.72, 4.45, 6.73, all P < 0.05). The Sobs index in the blank control group was higher than that in the western medicine group. There was no significant difference in the Sobs index between blank control and traditional Chinese medicine groups and between western medicine and traditional Chinese medicine groups (both P > 0.05). Principal coordinate analysis revealed that compared with the blank control group, Actinomycetes decreased and Proteobacteria and Desulfurization bacteria increased at the phylum level in the model group, while compared with the blank control group, Bacteroides, Rombutzia,Trichospirillus, and Parabacteroides increased, and Prevotella, Clostridium, Brucella, and Ruminococcus decreased at the genus level. Compared with the western medicine group, Bacillus, Prevotella, Brucella, and Prevotellidae in the traditional Chinese medicine group increased, while Clostridium, Pectinobacter, Christensen, and Trichospirillus decreased in the traditional Chinese medicine group. There was a statistically significant difference in the composition of the bacterial population between groups (all P < 0.05). Conclusion:There is an imbalance in intestinal microecology in a rat model of chronic obstructive pulmonary disease. Modified Buzhong Yiqi Decoction can regulate the intestinal microecology environment, improve the structure of intestinal flora, and increase the diversity and abundance of intestinal flora.

Study on the mechanism of Taohong siwu decoction improving peripheral nerve injury induced by paclitaxel in rats / 中国药房

OBJECTIVE To explore the mechanism of Taohong siwu decoction （THD） improving peripheral nerve injury induced by paclitaxel （PTX） in rats. METHODS The effects of THD （1 g/mL drug-containing serum） and PTX （0.1 μmol/L） alone or in combination on the proliferation rate of Schwann cells line RSC96 as well as the expressions of lysosomal-associated membrane protein-2 （LAMP2）， autophagy marker protein yeast Atg 6 homolog （Beclin1）， phosphatidylinositol 3-kinase （PI3K）， protein kinase B （Akt）， and mammalian target of rapamycin （mTOR） were investigated， and then compared with autophagy promoter rapamycin and autophagy inhibitor 3-methyladenine （3-MA）. The effects of high-dose and low-dose THD on the expressions of myelin basic protein （MBP） and myelin protein zero （MPZ）， S100 calcium-binding protein （S100）， LAMP2， Beclin1， PI3K， Akt and mTOR were tested at the end of the experiment. RESULTS After treatment of THD+PTX， the proliferation rate of RSC96 cells was significantly higher than those treated with PTX alone. After treatment of THD+PTX or THD+ 3-MA， the protein expressions of LAMP2 and Beclin1 in RSC96 cells were significantly higher than those treated with PTX or 3- MA alone， while the protein expressions of PI3K， Akt and mTOR were significantly lower than those treated with PTX or 3-MA alone （P＜0.05）. Compared with model group， the protein expressions of MBP， MPZ， S100， LAMP2 and Beclin1 in sciatic nerve of rats were increased significantly in THD high-dose and low-dose groups， while the protein expressions of PI3K， Akt and mTOR were significantly decreased （P＜0.05）. CONCLUSIONS THD may activate Schwann cell autophagy by inhibiting the PI3K/Akt/ mTOR signaling pathway， thereby improving peripheral nerve injury caused by PTX.

Influence of Huayu xiaozhong decoction on inflammatory response in rats with deep vein thrombosis / 中国药房

OBJECTIVE To investigate the influence of Huayu xiaozhong decoction （HXD） on inflammatory response in rats with deep vein thrombosis （DVT）. METHODS The male SD rats were divided into control group （CK group）， model group （Model group）， HXD low-dose group （HXD-L group， HXD 10.86 mg/kg）， HXD medium-dose group （HXD-M group， HXD 21.71 mg/kg）， HXD high-dose group （HXD-H group， HXD 32.57 mg/kg）， positive control group （LMWHS group， low molecular weight heparin sodium 600 IU/kg）， silent information regulator 2 （SIRT2） inhibitor group （AK-7 group， AK-7 20 mg/kg）， HXD-M+AK-7 group （HXD 21.71 mg/kg+AK-7 20 mg/kg）， with 12 rats in each group. Except for the CK group， the DVT rat was induced by the Reyers method in other groups； after modeling， administration groups were given relevant medicine intragastrically/intraperitoneally， once a day， for consecutive 2 weeks. Twenty-four hours after the last medication， the coagulation function indexes [activated partial thromboplastin time （APTT）， thrombin time （TT）， prothrombin time （PT）， fibrinogen （FIB）] and inflammatory indexes in serum and inferior vena cava tissue [interleukin-1β （IL-1β）， IL-6， tumor necrosis factor-α （TNF-α）] of rats were detected. The formation of thrombus was observed， and the wet and dry masses of the thrombus were weighed. The protein expressions of tissue factor （TF） and SIRT2 as well as the phosphorylation and acetylation levels of nuclear factor kappa B （NF-κB） p65 in inferior vena cava tissue were detected. RESULTS Compared with CK group， APTT， TT and PT of rats in Model group were shortened significantly（P＜0.05）； the content of FIB， the levels of IL-1β， IL-6 and TNF-α， wet weight and dry weight of venous thrombus， TF protein staining score， the phosphorylation and acetylation levels of NF-κB p65 protein increased significantly （P＜0.05）； the inferior vena cava was full of thrombus， and the protein expression of SIRT2 decreased （P＜0.05）. Compared with Model group， above indexes of HXD-L group， HXD-M group， HXD-H group and LMWHS group were improved， while the improvement effects of HXD-M group， HXD-H group and LMWHS group were significantly better than those of HXD-L group （P＜0.05）. The trends of the corresponding indicators in AK-7 group were opposite to the above （P＜0.05）； AK-7 attenuated the inhibitory effect of medium-dose HXD on the inflammatory response in model rats （P＜0.05）.CONCLUSIONS HXD may inhibit the inflammatory response of DVT rats by activating SIRT2/NF-κB signaling pathway.
