Effects of Huangqin Tang on NLRP3/Caspase-1 pathway in mice model of ulcerative colitis / 中国中药杂志

The aim of this study was to explore the effects of Huangqin Tang(HQT) on the NLRP3/Caspase-1 signaling pathway in mice with DSS-induced ulcerative colitis(UC). C57BL/6J mice were randomly divided into a blank group, a model group(DSS group), and low-, medium-and high-dose HQT groups(HQT-L, HQT-M, and HQT-H), and western medicine mesalazine group(western medicine group). The UC model was induced in mice. Subsequently, the mice in the HQT-L, HQT-M, HQT-H groups, and the western medicine group were given low-, medium-, high-dose HQT, and mesalazine suspension by gavage, respectively, while those in the blank and DSS groups were given an equal volume of distilled water by gavage. After 10 days of administration, the body weight, DAI scores, and colonic histopathological score of mice in each group were determined. The levels of IL-6, IL-10, IL-1β, and TNF-α in serum were determined by ELISA. The mRNA expression of NLRP3 and Caspase-1 in colon tissues was determined by RT-qPCR. The protein expression of NLRP3 and Caspase-1 in colon tissues was detected by immunohistochemistry. The results showed that compared with the blank group, the DSS group showed decreased body weight of mice and increased DAI scores and intestinal histopathological score. Compared with the DSS group, the HQT groups and the western medicine group showed improved DAI scores, especially in the HQT-M, HQT-H, and the western medicine groups(P<0.05). The intestinal histopathological scores of the HQT groups and the western medicine group significantly decreased, especially in the HQT-M, HQT-H, and the western medicine groups(P<0.05). In addition, compared with the blank group, the DSS group showed elevated expression of NLRP3 and Caspase-1 in colon tissues, increased serum levels of IL-6, IL-1β, and TNF-α, and decreased IL-10 level. Compared with the DSS group, the HQT groups and the western medicine group displayed decreased expression of NLRP3 and Caspase-1 in colon tissues, reduced serum levels of IL-6, IL-1β, and TNF-α, and increased IL-10 level. The improvement was the most significant in the HQT-H group and the western medicine group(P<0.01). In conclusion, HQT may reduce the expression of NLRP3 and Caspase-1 in colon tissues, reduce the se-rum levels of IL-6, IL-1β, and TNF-α, and increase the expression of IL-10 by regulating the classic pyroptosis pathway of NLRP3/Caspase-1, thereby improving the symptoms of intestinal injury and inflammatory infiltration of intestinal mucosa in DSS mice to achieve its therapeutic effect.

OBJECTIVE: To evaluate the efficacy of the Shugan Jieyu capsule on improving sleep and emotional disorder during Coronavirus disease 2019 (COVID-19) convalescence. METHODS: We conducted a randomized, double-blind, placebo-controlled trial, and recruit 200 COVID-19 convalescence patients and then divide the subjects into two groups respectively: the experimental group ( 100) and the control group ( 100). Patients in the control group were given doses as a placebo, while those in the experimental group were given Shugan Jieyu capsule. The investigators mainly observed the differences between the two groups before and after treatment in terms of the rate of reduction and the rate of efficiency in Hamilton Depression Scale (HAMD-17) total scores from baseline, and recorded the scores of Hamilton Anxiety Scale (HAMA), Patient Health Questionnaire-15 (PHQ-15), Insomnia Severity Index (ISI) and Treatment Emergent Symptom Scale at 2 week, the 4 week and the 6 week respectively after treatment, and compared the differences between the groups. And the occurrence of adverse events was recorded. RESULTS: After 6-week treatment, there were statistically significant differences in the rate of reduction as well as efficiency in HAMD-17 scores, HAMA Total Scores, PHQ-15 Score, ISI Score from baseline in the experimental group and control group (< 0.05). There were 4 adverse events in the experimental group and 1 in the control group. CONCLUSION: Shugan Jieyu capsule could significantly improve sleep and emotional disorder in patients during COVID-19 convalescence.

The Single-Nucleotide Polymorphism of miR-27a rs895819 and the Expression of miR-27a in Helicobacter pylori-Related Diseases and the Correlation with the Traditional Chinese Medicine Syndrome.

Aims: The study aims to explore the effects of the single-nucleotide polymorphism of miR-27a and its expression in Helicobacter pylori (H. pylori)-related diseases and the relationship between gastric pathology and traditional Chinese medicine (TCM). Methods: Subjects were classified into six histopathological groups and five TCM syndrome groups. All specimens underwent H. pylori detection through rapid urease test and methylene blue staining. Histopathological characteristics were observed by hematoxylin-eosin. The expression of miR-27a and its genotype were, respectively, detected by Quantitative Real-Time PCR and direct sequencing. Results: H. pylori promoted the malignant evolution of gastric mucosa and were involved in the formation of TCM syndrome. In H. pylori-positive patients, the frequency of miR-27a CT genotype at the rs895819 locus and its expression in the gastric cancer group were higher than those in other pathological groups. TCM syndrome had a close relationship with histopathological changes, and patients with spleen-qi deficiency syndrome had a higher risk of gastric cancer than other syndromes, regardless of H. pylori infection. Conclusion: The C allele at miR-27a rs895819 locus may be an oncogene in gastric cancer. High levels of miR-27a could play an important role in gastric malignant evolution, especially cancerization. There is a certain connection between TCM syndrome and pathological changes of the gastric mucosa to some extent, where patients with SQD syndrome had a higher risk of GC.

Efficacy and safety of Qingre-Chushi therapies in active ulcerative colitis: A network meta-analysis.

BACKGROUND: Ulcerative colitis (UC) is a chronic inflammatory disease with an increasing incidence in the world. Qingre-Chushi therapies (QC) can alleviate clinical symptoms. Therefore, a network meta-analysis was conducted to systematically evaluate the efficacy and safety of QC in the treatment of active UC patients. METHODS: 7 databases were screened and relevant randomized controlled trials were selected. The tools of Cochrane Handbook and the GRADE system were conducted to assess the quality of outcomes. Pooled risk ratio or standard mean difference was calculated with 95% credible interval for outcomes measurement using the random-effects model. The surface under the cumulative ranking curve (SUCRA) was performed to rank the treatments. The larger SUCRA scores, the more effective interventions. RESULTS: A total of 3560 articles were identified and 21 studies including 1829 participants were included for further analysis. Totally, 9 therapies regimens were compared: oral mesalazine, mesalazine enema, mesalazine suppository, oral mesalazine + mesalazine enema, oral QC, oral QC + oral mesalazine, QC enema, oral QC + QC enema, and oral mesalazine + QC enema. Based on the SUCRA plot, oral QC + oral mesalazine was the best treatment in inducing clinical response; oral QC + QC enema had the best efficacy in the improvement of Mayo scores and alleviating abdominal pain; oral mesalazine + mesalazine enema was the optimal therapy in the endoscopic improvement and reducing diarrhea; QC enema + oral mesalazine was the best option in preventing bloody stool. CONCLUSION: This study confirmed the efficacy and safety of QC in treating active UC and suggested that the combination of oral medications with topical can achieve more benefits.

Pharmacological treatments of Chinese herbal medicine for irritable bowel syndrome in adults: A network meta-analysis of randomized controlled trials.

INTRODUCTION: Plenty of clinical studies have suggested the value of Chinese herbal medicine (CHM) for patients with irritable bowel syndrome (IBS), but their efficacy and safety have not been systematically concluded yet. This article aimed to compare and rank the therapeutic effect and safety of CHM with routine pharmacotherapies and placebo in the treatment of IBS. METHODS: Randomized controlled trials regarding CHM to treat IBS were searched in six databases from inception to Jan 31, 2020. A network meta-analysis was conducted to analyze the data of included publications. The quality assessment was assessed by Cochrane Handbook and GRADEpro software. The risk ratio was calculated for dichotomous outcomes while the standardized mean difference was used for continuous variables with 95% credible intervals. A Funnel plot was performed to evaluate publication bias. The surface under the cumulative ranking curve was conducted to rank the included interventions. Data were analyzed with STATA 15.0 and Review Manager 5.3. RESULT: 3194 records were searched, and 28 eligible trials involving 3323 patients ere identified. Compared with conventional therapies and placebo, Jianpi-Chushi therapy showed significant improvement in adequate relief and IBS symptom severity scale; Shugan-Jianpi therapy showed the best efficacy in relieving the abdominal pain and abdominal distension; Wenshen-Jianpi therapy had a better effect on avoiding adverse effects and improving stool character. CONCLUSION: This study confirmed that CHM could be beneficial for patients with IBS in relieving their clinical symptoms and should be recommended as alternative therapies. The quality of evidence in this study based on the GRADE system was "low".

Efficacy and safety of non-pharmacological interventions for irritable bowel syndrome in adults.

BACKGROUND: Although nonpharmacological interventions (NPI) for irritable bowel syndrome (IBS) have been applied clinically, their relative efficacy and safety are poorly understood. AIM: To compare and rank different NPI in the treatment of IBS. METHODS: Five electronic databases were searched from their inception to January 12, 2020. Data of included publications were analyzed using network meta-analysis (NMA). Quality of endpoints were assessed by tools of the Cochrane Handbook and the GRADEpro software. Pooled relative risk or standardized mean difference with their corresponding 95% confidence intervals were used for statistical analysis. Surface under the cumulative ranking curve (SUCRA) probability value was conducted to rank the examined interventions. Sensitivity analysis was performed to verify the robustness of results and test the source of heterogeneity. RESULTS: Forty randomized controlled trials with 4196 participants were included in this NMA. Compared with routine pharmacotherapies and placebo, acupuncture and cognitive behavioral therapy (CBT) had better efficacy in relieving IBS symptoms. Based on the SUCRA values, acupuncture ranked first in improving overall clinical efficacy and avoiding adverse effects. CBT ranked first in lowering the scores of IBS symptom severity scale, self-rating anxiety scale and self-rating depression scale. CONCLUSION: This study confirmed the efficacy and safety of NPI for improving IBS symptoms, which to some extent recommended several interventions for clinical practice.

Different Traditional Herbal Medicines for the Treatment of Gastroesophageal Reflux Disease in Adults.

BACKGROUND/AIMS: Traditional Herbal Medicines (THM) have been being used for gastroesophageal reflux disease (GERD) for a long time, but clinical evidence is still scarce. We evaluated different THM prescriptions for GERD in adults. METHODS: Data added to nine online databases from their inception to November 30, 2019, were systematically searched. All relevant randomized controlled trials (RCTs) were included and were combined with Bayesian network analysis. The Cochrane Collaboration's risk of bias tool and GRADE profiler version 3.6 were respectively employed to evaluate the quality of evidence of outcomes. RESULTS: Seventeen publications involving 1441 participants were retrieved. The results of our analysis suggested that Jianpi therapy+proton pump inhibitors (PPIs) and Ligan Hewei therapy respectively ranked first in overall clinical efficacy and efficacy under gastroscope; Ligan Hewei therapy+PPIs was the optimum intervention in the improvement of acid regurgitation and heartburn. CONCLUSION: This research indicates that Ligan Hewei therapy and Jianpi therapy, or these therapies separately combined with PPIs, should be recommended as appropriate complementary and alternative treatments based on the specific characteristics of GERD. However, additional well-designed RCTs with high methodological quality are still needed for future research.

Interaction of Cyclooxygenase-2 with Helicobacter pylori Induces Gastric Chronic Nonresolving Inflammation and the Formation of Syndrome of Internal Block of Static Blood in Helicobacter pylori-Related Gastric Diseases.

Cyclooxygenase-2 (COX-2) is an inducible enzyme stimulated by various inflammatory factors (IFs). Chronic gastritis is a classic model of "inflammation-cancer transformation" and Helicobacter pylori-related gastric diseases (HPGD) are specific ones of this model. Traditional Chinese Medicine (TCM) syndromes could play a predictive role in gastric histopathological evolution. To search for early warning evidence about "inflammation-cancer transformation," this study is about to explore interaction of COX-2 with Helicobacter pylori (Hp) in HPGD with different TCM syndromes. All included subjects underwent endoscopy and biopsy. Hp infection was detected by rapid urease test and methylene blue staining. Histopathological characteristics and COX-2 expression in gastric mucosa (GM) were, respectively, observed by hematoxylin-eosin and Elivision™ plus. SPSS 18.0 and Stata 11.0 statistical software packages were used for statistical analysis. Results of immunohistochemical staining in this study showed COX-2 expression in Hp-positive patients was stronger than that in Hp-negative ones. Spearman' analysis indicated that degrees of both Hp infection and COX-2 expression were positively correlated with those of gastric inflammation and inflammatory activity. Compared with the relative normal group, both severe dysplasia group and gastric carcinoma group had more severe Hp infection and COX-2 expression. Compared with the nonsyndrome, syndrome of internal block of static blood (IBSB) had higher scores in semiquantitative analysis of COX-2 protein expression among TCM groups. Moreover, multivariate logistics regression analysis suggested that patients with Hp infection could increase the risk of IBSB. These results indicated that COX-2 interacting with Hp could play an important role in transforming gastric chronic nonresolving inflammation into carcinoma in subjects with HPGD, as well as inducing the formation of IBSB. HPGD together with IBSB could be an early warning evidence for GM with histopathological evolution from benign to malignant.

Potential SARS-CoV-2 3CL protease inhibitors selection from TCMSP platform by molecular docking approach / 中草药

Objective: To identify potential SARS-CoV-2 3CL protease inhibitors from the traditional Chinese medicine systems pharmacology database and analysis platform (TCMSP) by molecular docking approach. Methods: To alternate extensive compounds experimental screening processes, a Computer-Aided Drug Design (CADD) based molecular docking technology was performed to explore existing drug repurposing possibilities. Molecular docking model with Schrodinger suit 2018 was used to evaluate the binding abilities between TCMSP 13 143 compounds and SARS-CoV-2 3CL protease receptor-binding domain (PBD ID 6LU7), which involving in mediating viral replication and transcription functions. According to the constructed docking system, potential compounds were screened according to docking score, oral bioavailability (OB), and drug-likeness (DL). At last, a compounds-herb-target organ-function network was constructed. Results: Compared with 6LU7 original ligand docking score (-7.734), a total of 498 compounds were identified with lower docking score against 6LU7 targets. These compounds were further reduced to 60 high-priority compounds, based on OB (more than 30) and DL (more than 0.18). Meanwhile, these 60 compounds were found to interact with the amino acid residues (GLU166, GLY143, ASP187, CYS145, GLN189, LEU141, etc.) which were critically involved in the 6LU7 domain mainly by hydrogen-bonded interaction. The network exploring results revealed that these potential compounds were mainly attributed to Glycyrrhizae Radix et Rhizoma, Mori Cortex, Rhododendron dauricum, Polygoni Cuspidati Rhizoma et Radix, and Plantaginis Herba, etc., which associates with acute lung syndromes induced by SARS-CoV-2, with the effect of clearing heat and removing toxin, relieving cough and dispelling phlegm and lung-draining and relieving asthma. Conclusion: Molecular docking method provides a useful tool for the screening of SARS-CoV-2 3CL protease inhibitors from TCMSP platform.

Research Progress on Application and Mechanism of Traditional Chinese Medicine in Gout / 中国实验方剂学杂志

Gout is the second largest metabolic disease after diabetes, with a high incidence worldwide. Gout is a common and complex arthritic disease that, if left untreated, can damage joints and, in severe cases, lead to kidney stones and even life-threatening kidney failure. Although western medicine has also made significant achievements in the treatment of gout, it is often accompanied by gastrointestinal reactions, liver injury and other adverse reactions, and is prone to relapse after drug withdrawal, making the radical treatment of gout a difficult problem. Traditional Chinese medicine (TCM) used in gout have relatively long history, TCM has the characteristics of multiple ingredients targets, not only can produce related enzyme activity by inhibiting the uric acid(UA) and lowering uric acid generation, also can reduce uric acid by promoting uric acid excretion, except the uric acid reduction most applied in gout neighborhood of TCM can effectively reduce joint inflammation. TCM is mild, and the incidence of adverse reactions in the treatment of gout is significantly lower than that of western medicine. Some TCM can even play a role while protecting the kidney, so TCM is expected to solve the problem of treating gout. In recent years, a large number of studies have been conducted on the application of TCM in the gout neighborhood at home and abroad. By summarizing the studies on the application of TCM in the gout disease in the past 10 years, the mechanism of action and material basis have been summarized and analyzed, in the hope of providing references for the studies on the prevention and treatment of gout by TCM.

Efficacy of Jianpi Liqi therapy for functional dyspepsia: A meta-analysis of randomized, positive medicine-controlled trials.

BACKGROUND: We performed this meta-analysis to assess the efficacy and safety of Jianpi Liqi therapy (JLT), a traditional Chinese medicine therapy, in treating functional dyspepsia (FD). METHODS: We systematically searched 13 databases from their inception to 15th, May 2019. Eligible studies were randomized controlled trials (RCTs) that compared JLT medicine with conventional pharmacotherapy (CP) in treating patients with FD. Cochrane Collaboration tool, Review Manager 5.3 and STATA 11.0, GRADE profiler 3.6 were used for evaluating risk of bias, analyzing, and assessing quality of evidence respectively. RESULTS: After exclusions, 15 RCTs including a total of 1451 participants were included for analysis. We found evidence that JLT had better efficacy than CP (domperidone, omeprazole, esomeprazole, mosapride, lansoprazole, compound digestive enzymes, lactasin tablets) for FD (OR 0.34; 95% CI 0.26, 0.45; P < .00001). Moreover, JLT had more improvement on symptoms including abdominal pain, abdominal distention, early satiety, belching, poor appetite, and fatigue compared with CP. In addition, serious adverse events were not observed in treatment courses. CONCLUSION: This meta-analysis suggested that JLT appears to have better efficacy in treating FD compared with CP. It may be an effective and safe therapy option for patients with FD. Though, more large-sample and strictly designed RCTs are needed to confirm our findings.PROSPERO registration number: CRD42019133241.

Effects of Shengmai Jianghuang San on intestinal flora in nude mice with radio resistant cells of nasopharyngeal carcinoma / 中国中药杂志

Modern pharmacological studies have shown that Shengmai San has the effects of enhancing immunity and improving blood circulation, and Curcumae Longae Rhizoma(Jianghuang) has anti-inflammatory, anti-cancer, anti-oxidation and other functions. Shengmai San combined with Jianghuang is a new research direction in the study of anti-tumor of traditional Chinese medicines. The main treatment for nasopharyngeal carcinoma is radiation therapy, but radiation therapy can cause a variety of side effects, and it also changes the composition of the intestinal flora. In this study, the 16 s rDNA sequencing platform was used to perform macro-sequence sequencing of the intestinal flora samples of nude mice bearing the veins of Shengmai Jianghuang San, and then the results of intestinal flora data were analyzed to investigate the effect of Shengmai Jianghuang San on tumors. The results showed that Shengmai Jianghuang San combined with irradiation could enhance the therapeutic effect of tumor treatment. Radiation therapy would reduce the total number and diversity of intestinal flora in nude mice, and also change the structure of the flora. Shengmai Jianghuang San could protect the diversity of colonies, and also partially restore the colony imbalance caused by irradiation. This study provides a research idea for Shengmai Jianghuang San as a sensitizing adjuvant for radiotherapy of nasopharyngeal carcinoma.

A UPLC method has been developed for simultaneous determination of nine furanocoumarins of Angelica dahurics,and was used for quality evaluation of A. dahurica from different habitats. ACQUITY UPLC BEH C18 chromatographic column was employed,the separation was performed with the mobile phase consisting of acetonitrile and water,and the detection wavelength was set at254 nm. This method was used to simultaneously determine the content of xanthotoxol,oxypeucedaninhydrate,byak-angelicin,psoralen,xanthotoxin,bergapten,oxypeucedanin,imperatorin and isoimperatorin in A. dahurica from different habitats. Then,the further quality assessment of the drug was carried out by similarity evaluation,cluster analysis( CA),principal component analysis( PCA),and orthogonal partial least squares discriminant analysis( OPLS-DA). The content order of measured furanocoumarins from high to low was: oxypeucedanin>imperatorin>isoimperatorin>oxypeucedaninhydrate>bergapten>byak-angelicin>xanthotoxin>xanthotoxol>psoralen,with the mean content 2. 844,1. 277,0. 649 2,0. 216 2,0. 129 8,0. 062 68,0. 052 68,0. 019 30,0. 018 19 mg·g-1,respectively. There were difference between the batches of the drug,and the quality was influenced by smouldering sulphur based on the results of chemical pattern recognition and content determination. Finally,six active ingredients were recognized as the quality makers using OPLS-DA method. The validated UPLC fingerprint combined with chemical pattern recognition method can be used in the quality control and evaluation of A. dahurica.

Polysaccharide extracts of Astragalus membranaceus and Atractylodes macrocephala promote intestinal epithelial cell migration by activating the polyamine-mediated K+ channel.

Astragalus membranaceus (Radix Astragali, RA) and Atractylodes macrocephala (Rhizoma Atractylodis Macrocephalae, RAM) are often used to treat gastrointestinal diseases. In the present study, we determined the effects of polysaccharides extracts from these two herbs on IEC-6 cell migration and explored the potential underlying mechanisms. A migration model with IEC-6 cells was induced using a single-edged razor blade along the diameter of cell layers in six-well polystyrene plates. The cells were grown in control media or media containing spermidine (5 µmol·L-1, SPD), alpha-difluoromethylornithine (2.5 mmol·L-1, DFMO), 4-Aminopyridine (40 µmol·L-1, 4-AP), the polysaccharide extracts of RA or RAM (50, 100, or 200 mg·L-1), DFMO plus SPD, or DFMO plus polysaccharide extracts of RA or RAM for 12 or 24 h. Next, cytosolic free Ca2+ ([Ca2+]cyt) was measured using laser confocal microscopy, and cellular polyamine content was quantified with HPLC. Kv1.1 mRNA expression was assessed using RT-qPCR and Kv1.1 and RhoA protein expressions were measured with Western blotting analysis. A cell migration assay was carried out using Image-Pro Plus software. In addition, GC-MS was introduced to analyze the monosaccharide composition of both polysaccharide extracts. The resutls showed that treatment with polysaccharide extracts of RA or RAM significantly increased cellular polyamine content, elevated [Ca2+]cyt and accelerated migration of IEC-6 cells, compared with the controls (P < 0.01). Polysaccharide extracts not only reversed the inhibitory effects of DFMO on cellular polyamine content and [Ca2+]cyt, but also restored IEC-6 cell migration to control level (P < 0.01 or < 0.05). Kv1.1 mRNA and protein expressions were increased (P < 0.05) after polysaccharide extract treatment in polyamine-deficient IEC-6 cells and RhoA protein expression was increased. Molar ratios of D-ribose, D-arabinose, L-rhamnose, D-mannose, D-glucose, and D-galactose was 1.0 : 14.1 : 0.3 : 19.9 : 181.3 : 6.3 in RA and 1.0 : 4.3 : 0.1 : 5.7 : 2.8 : 2.2 in RAM. In conclusion, treatment with RA and RAM polysaccharide extracts stimulated migration of intestinal epithelial cells via a polyamine-Kv1.1 channel activated signaling pathway, which facilitated intestinal injury healing.

Aim To explore the antidepressant effect and the mechanism of self-made prescription of strengthening spleen and replenishing Qi ( SMP-SS-RQ) . Methods The depression model of chronic un-predictable mild stress ( CUMS ) was established in mice. The animals were randomly divided into control group, model group, SMP-SSRQ low, middle and high dose groups (8, 16, 32 mg·kg-1), with 12 mice for each group. The control group and the model group were given the same volume of saline, and other groups were given corresponding dose of SMP-SSRQ. Animals of each group were administered by gavage twice a day for two weeks. Behavioral indexes of mice were deter-mined by open field experiment, sugar consumption test, forced swimming test and tail suspension test. Quantitative real-time PCR (qPCR) and Western blot were respectively performed to detect mRNA and pro-tein expression levels of Igsf11 , Pdia2 and Sec14 l2 inprefrontal cortex and hippocampus. Results Com-pared with model group, depressed mice' s horizontal mobile score, upright number and the sugar water pref-erence index increased and FST as well as TST de-creased in all SMP-SSRQ groups(P<0.05). The de-pression symptoms in mice were obviously improved by SMP-SSRQ therapy. Low and high doses of SMP-SSRQ significantly reduced mRNA and protein expression lev-el of Igsf11 , Pdia2 and Sec14 l2 in the prefrontal cortex and hippocampus of the depressed mice, presenting significant statistical difference compared with model group ( P<0.05 ) . Conclusions SMP-SSRQ can ef-fectively improve mouse depressive behavior, and its mechanism may be related to the down-regulation of Igsf11 , Pdia2 and Sec14 l2 in mouse prefrontal cortex and hippocampus.

Q-markers in Naoxintong Capsules by using multivariable statistical and "components-targets-diseases" network analysis / 中草药

Objective This study aimed to establish an integral quality control method for Naoxintong capsules based on the theory of quality markers (Q-marker) in traditional Chinese medicine via multivariable statistical calculation and "active compounds-targets" network construction. Methods Multi-statistical methods were firstly carried out to explore the specific components from different batches of Naoxintong Capsules. The "Q-markers-targets-pathways-diseases" network was constructed using the Bioinformatics Analysis Tool for Molecular Mechanism of Traditional Chinese Medicine (BATMAN-TCM) online analysis tool, and biological information annotations were made. Moreover, a simultaneously determination method for Q-markers was established by using ultra-high performance liquid chromatography (UPLC). Results Nine compounds were chose as the Naoxintong Q-markers capsules including mulberroside A, hydroxysafflor yellow A, paeoniflorin, ferulic acid, calycosin-7-glucoside, rosemary acid, salvianolic acid B, formononetin, and tanshinone IIA. To verify the prediction, target network construction analysis was performed and indicated that the nine Q-markers mainly targeted five proteins which were PTGIS, PTGS2, CHRNA10, ENPP1, and ADORA2A. Methodological validation showed that the established UPLC method had good linear relationship (r<0.999), and all RSD values were lower than 3% in the repeatability, stability, and precision test. Conclusion Based on the multivariate statistics, network pharmacology analysis, and UPLC multi-component quantitative analysis, a multi-angle analysis method for effective components can be established for the integral quality control of Naoxintong Capsules.
