Impact of lockdown policies during the COVID-19 outbreak on a trauma center of a tertiary hospital in China.

BACKGROUND: Coronavirus disease 2019 (COVID-19) is a major and costly public health emergency. AIM: To investigate the impact of China's lockdown policies during the COVID-19 outbreak on the level I trauma center of a tertiary comprehensive hospital of Traditional Chinese Medicine. METHODS: All patients admitted to our trauma center during a lockdown in 2020 and the same period in 2019 were enrolled. We collected data on demographics, daily visits, injury type, injury mechanism, injury severity score, and patient management for comparative analysis. RESULTS: The total number of patients in the trauma center of our hospital decreased by 50.38% during the COVID-19 Lockdown in 2020 compared to the same period in 2019. The average number of trauma visits per day in 2019 was 47.94, compared to 23.79 in 2020. Comparing the patients' demographic data, loss of employment was the most predominate characteristic in 2020 compared to 2019, while there was no significant difference in gender, age, and marital status between both periods. During the lockdown period, the proportion of traffic accident-related injuries, injuries due to falls greater than 1.5 m, and mechanical injuries decreased significantly, whereas the proportion of injuries caused by falls less than 1.5 m, cuts, assault, bites, and suicidal tendencies and other injuries increased relatively. In addition, the proportion of patients with minor injuries increased and serious injuries decreased during the lockdown. The hospitalization rate increased significantly, and there was no significant difference in emergency surgery and death rates. CONCLUSION: The lockdown policies during the COVID-19 outbreak significantly altered the number and mechanism of traumatic events in our hospital, which can be monitored regularly. Our results suggest that mandatory public health prevention and control measures by the government can reduce the incidence of traumatic events and the severity of traumatic injuries. Emergency surgery and mortality rates remain high, increased because of factors such as family injury and penetrating injury, and hospitalization rates have increased significantly. Therefore, our trauma center still needs to be fully staffed. Finally, from the perspective of the injury mechanism, indoor trauma is a major risk during a lockdown, and it is particularly important to develop prevention strategies for such trauma to reduce the medical burden of the next catastrophic epidemic.

Efficacy of Danggui Buxue decoction on diabetic nephropathy-induced renal fibrosis in rats and possible mechanism.

OBJECTIVE: To observe the efficacy of Danggui Buxue decoction (, DBD) on diabetic nephropathy-induced renal fibrosis in rats, and to study the possible mechanism. METHODS: Sixty male Goto Kakizaki (GK) rats were randomly assigned to the model group, gliquidone group, astragaloside IV group, and high-, medium- and low-doses DBD groups. After 8 weeks, changes in body weight, blood glucose, serum creatinine, serum urea nitrogen, and total cholesterol were observed. Changes in transforming growth factor-ß1 (TGF-ß1), Smad3, and Smad5 pathways and the expression of the fibrosis-related proteins collagen IV (col IV), α-smooth muscle actin (α-SMA), and vimentin were assessed. The degree of renal fibrosis was observed by immunohistochemistry and Mason staining. The expression of interleukin 6 (IL-6), interleukin 10 (IL-10), tumor necrosis factor (TNF-α), and C-reactive protein (CRP) in the kidneys was assessed using enzyme linked immunosorbent assay. RESULTS: Our experiments showed that DBD effectively reduced blood glucose, blood urea nitrogen, and creatinine levels after 8 weeks of administration, improved renal function in diabetic rats, alleviated renal fibrosis, and reduced the renal tissue levels of IL-6, IL-10, TNF-α, and CRP. Furthermore, DBD decreased the expression of TGF-ß1, Smad3, col IV, α-SMA, and vimentin in renal tissues and increased the expression of Smad5. CONCLUSIONS: DBD ameliorates diabetic renal interstitial fibrosis by modulating the TGF-ß1/Smads pathway.

Study on the objectivity and biological mechanism of Psoralea corylifolia Linn.'s 'Great dryness damages the liver' / 药学学报

According to the theory of 'Xingben Dazao' of Psoralea corylifolia Linn. (BL), the susceptible syndromes and biomarkers of liver injury caused by BL were searched. Rat models of kidney-yin deficiency syndrome (M_yin) and kidney-yang deficiency syndrome (M_yang) were established, and all animal experimental operations and welfare following the provisions of the First Affiliated Experimental Animal Ethics and Animal Welfare Committee of Henan University of Traditional Chinese Medicine (No. YFYDW2020017). The results showed that BL significantly decreased the body weight, water intake, and urine weight of M_yin rats and increase the organ indexes of the liver, testis, adrenal gland, and spleen and the expression of alanine aminotransferase (ALT). Meantime, BL significantly increased the urine weight of M_yang rats and decreased the expression of ALT and aspartate aminotransferase (AST). Hematoxylin and eosin (HE) staining showed that BL could aggravate inflammatory infiltration of hepatocytes in rats with M_yin and alleviate liver injury in rats with M_yang. Metabolomics identified 17 BL co-regulated significant differential metabolic markers in M_yin and M_yang rats. Among them, 8 metabolites such as glutamine, quinolinate, biliverdin, and lactosylceramide showed opposite trends, mainly involving cysteine and methionine metabolism, tyrosine metabolism, tryptophan metabolism, purine metabolism, sphingolipid metabolism, glycerol phospholipid metabolism, glutamine metabolism, and other pathways. M_yin/M_yang may be the susceptible constitution of BL for liver damage or protection, which may be related to the regulation of amino acid metabolism and sphingolipid metabolism. The study can provide some experimental data support for the safe and accurate use of BL in the clinical practice of traditional Chinese medicine.

Objective:To evaluate the application effect of the "group-based" teaching assistant (TA) guidance model in homogenized clinical skill training.Methods:A pilot study was conducted on the cardiopulmonary resuscitation training course, and 32 students majoring in clinical integrative Chinese and Western medicine (five-year program) who were admitted to Shanghai University of Traditional Chinese Medicine in 2018 were randomly divided into control group ( n = 16) and TA group ( n = 16). The control group received traditional teaching methods, and the TA group was further divided into subgroups A, B, C, and D, with four graduate TAs providing group-based teaching. The groups were compared in terms of their satisfaction and test scores. SPSS 25.0 was used for t-test and analysis of variance. Results:The satisfaction survey showed that compared with the control group, the TA group had significantly higher degree of satisfaction with the increased practical opportunities, clinical skill practical ability, learning effect, and overall satisfaction. The immediate test showed that there was no significant difference in test score between the TA group (85.19±2.93) points and the control group (82.75±4.52) points. The test 30 days later showed that the TA group (83.50±5.13) points had a significantly higher test score than the control group (74.68±3.87) points, and the control group had a significantly lower test score than that in the immediate test ( P <0.001); however, there was no significant difference in the TA group's score between the immediate test and the test 30 days later. Conclusion:The "group-based" TA guidance model has a good effect in homogenized clinical skill training, and has a stable long-term effect, with high student satisfaction.

OBJECTIVE: To primarily explore the effect and mechanism of Wenshen Yangxue decoction in promoting follicular development in elderly female mice. METHODS: Fifty Institute of Cancer Research mice were randomly divided into blank, controlled ovarian hyperstimulation (COH), low-dose Wenshen Yangxue decoction, medium-dose Wenshen Yangxue decoction, and high-dose Wenshen Yangxue decoction groups, with 10 mice in each group. The number of ovulations, number of fertilizations, mitochondrial adenosine triphosphate (ATP) level, and mitochondrial DNA (mtDNA) of oocytes in each group were compared. Reverse transcription-polymerase chain reaction and Western blotting were used to detect the mRNA and protein expression levels of silent information regulator 3 (Sirt3) and forkhead transcription factor O1 3a (FOXO3a). RESULTS: Wenshen Yangxue decoction significantly increased the number of ovulations in mice (P < 0.05) and promoted the formation of fertilized eggs. The ATP level and mtDNA copy number of mice oocytes in the high-dose groups were significantly higher than those in the COH group (P < 0.05). Wenshen Yangxue decoction significantly increased the mRNA and protein levels of Sirt3 and FOXO3a in mouse oocytes. CONCLUSION: Wenshen Yangxue decoction promoted the development of follicles in elderly female mice, increased the number of ovulations and improved fertility. Its mechanism may be related to increased mitochondrial energy metabolism and regulation of the Sirt3/FOXO3a pathway.

Mechanisms of Compound Kushen Injection for the treatment of bladder cancer based on bioinformatics and network pharmacology with experimental validation / 中国天然药物

Bladder cancer is the most common malignancy of the urinary system. Compound Kushen Injection (CKI) is a Chinese medicinal preparation that has been widely used in the treatment of various types of cancers in the past two decades. However, the pharmacological effect of CKI on bladder cancer is not still completely understood. In the current study, network pharmacology combined with bioinformatics was used to elucidate the therapeutic mechanism and potential targets of CKI in bladder cancer. The mechanism by which CKI was effective against bladder cancer was further verified in vitro using human bladder cancer cell line T24. Network pharmacology analysis identified 35 active compounds and 268 target genes of CKI. Bioinformatics data indicated 5500 differentially expressed genes associated with bladder cancer. Common genes of CKI and bladder cancer suggested that CKI exerted anti-bladder cancer effects by regulating genes such as MMP-9, JUN, EGFR, and ERK1. Functional enrichment analysis indicated that CKI exerted therapeutic effects on bladder cancer by regulating certain biological processes, including cell proliferation, cell migration, and cell apoptosis. In addition, Kyoto Encyclopedia of Genes and Genomes enrichment analysis implicated pathways related to cancer, bladder cancer, and the PI3K-Akt signaling pathway. Consistently, cell experiments indicated that CKI inhibited the proliferation and migration of T24 cells, and induced their apoptosis. Moreover, RT-qPCR and Western blot results demonstrated that CKI was likely to treat bladder cancer by down-regulating the gene and protein expression of MMP-9, JUN, EGFR, and ERK1. CKI inhibited the proliferation and migration, and induced the apoptosis of T24 bladder cancer cells through multiple biological pathways and targets. CKI also exhibited significant effects on the regulation of key genes and proteins associated with bladder cancer. Overall, our findings provide solid evidence and deepen current understanding of the therapeutic effects of CKI for bladder cancer, and further support its clinical use.

Study on alleviating effect of Glycyrrhizae Radix et Rhizoma on Psoraleae Fructus-induced liver injury based on network pharmacology and cell experiments / 中国中药杂志

This study was designed to explore the alleviating effect and mechanism of Glycyrrhizae Radix et Rhizoma against Psora-leae Fructus-induced liver injury based on network pharmacology and cell experiments. The active components of Glycyrrhizae Radix et Rhizoma and Psoraleae Fructus were first retrieved from the Encyclopedia of Traditional Chinese Medicine(ETCM), Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform(TCMSP), Comparative Toxicogenomics Database(CTD), and literature and further screened by SwissADME. The obtained 25 potential toxic components of Psoraleae Fructus and 29 flavonoids in Glycyrrhizae Radix et Rhizoma were input into the SwissTargetPrediction for target predication. A total of 818 targets related to liver injury were screened out based on GeneCards and MalaCards, and 91 common targets of Psoraleae Fructus, Glycyrrhizae Radix et Rhizoma, and liver injury were obtained from Venny. STRING was applied for constructing the PPI network, and Metascape for analyzing the biological processes and signaling pathways that common targets participated in. Cytoscape was used to construct the component-target-disease network and component-target-pathway network for Glycyrrhizae Radix et Rhizoma against Psoraleae Fructus-induced liver injury. The predicted core targets were proto-oncogene tyrosine-protein kinase(SRC), phosphatidylinositol 4,5-bisphosphate 3-kinase subunit alpha(PIK3 CA), RAC-alpha serine/threonine-protein kinase(AKT1), etc, with PI3 K-AKT signaling pathway, MAPK signaling pathway, apoptosis, Toll-like receptor signaling pathway, and NF-κB signaling pathway mainly involved. Following the scree-ning of the main toxic and pharmacodynamic components, the pharmacodynamic effects were investigated by cell experiments. The results showed that licochalcone A was mainly responsible for alleviating coryfolin-induced liver injury, licochalcone B for coryfolin-and psoralidin-induced liver injury, and echinatin for corylifolinin-and bakuchiol-induced liver injury. The preliminary revealing of the alleviating effect of Glycyrrhizae Radix et Rhizoma on Psoraleae Fructus-induced liver injury and the prediction of related mechanisms will provide reference for further mechanism research and reasonable clinical compatibility.

Ginsenoside Rg1 improves cognitive capability and affects the microbiota of large intestine of tree shrew model for Alzheimer's disease.

Ginsenoside Rg1 (Rg1) is traditional Chinese medicine with neuroprotective activity. Previous studies have demonstrated that Rg1 improves Alzheimer's disease (AD) and alters gut microbiology, but its mechanism remains to be elucidated, and thus far, its use in the treatment of AD has not been satisfactory. The present study investigated the improvement effects of Rg1 and its association with the microbiota of the large intestine. Following treatment with Rg1 in AD tree shrews, the treatment group demonstrated significantly shorter escape latency and crossed a platform more frequently in a water maze test. Western blotting demonstrated that Rg1 inhibited the expression of ß-secretase 1, while increasing microtubule-associated protein 2 and Fox-3 in the hippocampus. Immunohistochemical analysis revealed that Rg1 decreased the expression of amyloid ß, tau phosphorylated at serine 404 and pro-apoptotic factor Bax, while increasing the expression of Bcl-2 in the hippocampus and cortex. High throughput sequencing of 16S rRNA demonstrated that Rg1 altered the microbiota abundance of the large intestine. In conclusion, Rg1 affected the expression of apoptosis proteins, possessed a neuroprotective effect and may have a close association with the microbiota of large intestine by significantly reducing the abundance of Bacteroidetes and increasing the energy requirement of tree shrews.

Mechanism of Shaofu Zhuyu Decoction in treatment of EMT induced dysmenorrhea based on network pharmacology and molecular docking / 中国中药杂志

Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform(TCMSP) and Bioinformatics Analysis Tool for Molecular Mechanism of Traditional Chinese Medicine(BATMAN-TCM) were searched for the effective components and targets of Shaofu Zhuyu Decoction. The relevant targets for endometriosis(EMT) and dysmenorrhea were retrieved from the Comparative Toxicogenomics Database(CTD), Therapeutic Target Database(TTD), GeneCards, and DisGeNET with the terms of "endometriosis" and "dysmenorrhea". Cytoscape 3.8.0 was employed to construct the drug-active component-therapeutic target network. A protein-protein interaction(PPI) network was established by STRING 11.0. Analyze Network, the plug-in in the Cytoscape 3.8.0, was used to calculate the topological parameters of the nodes and screen out the critical proteins in the network. The potential therapeutic targets were imported into RStudio and subjected to Gene Ontology(GO) and Kyoto Encyclopedia of Genes and Genomes(KEGG) enrichment analyses with clusterProfiler package. Finally, the AutoDock Vina(Vina) platform was used for molecular docking to predict the binding degree of the main active components of Shaofu Zhuyu Decoction to key targets. As revealed by the screening results, 136 active components and 380 targets of Shaofu Zhuyu Decoction were obtained. Additionally, there were 1 627 targets related to EMT and 142 targets related to dysmenorrhea with 107 common targets, and 42 potential therapeutic targets of Shaofu Zhuyu Decoction for the treatment of EMT-induced dysmenorrhea. The targets such as interleukin 6(IL6) and prostaglandi-nendoperoxide synthase-2(PTGS2) were pivotal in the biological network of Shaofu Zhuyu Decoction intervention in EMT-induced dysmenorrhea, which involved multiple signaling pathways, including inflammation, hormones, and those promoted cell proliferation [e.g., mitogen-activated protein kinase(MAPK) and phosphatidylinositol-3 kinase(PI3 K)-protein kinase B(AKT)]. The results of molecular docking showed that the active components of Shaofu Zhuyu Decoction had good binding capacities to key targets such as IL6 and PTGS2. The findings of this study demonstrated that Shaofu Zhuyu Decoction could treat EMT-induced dysmenorrhea through multiple targets and multiple pathways, which could provide new ideas for investigating the underlying mechanism of Shaofu Zhuyu Decoction in the treatment of EMT-induced dysmenorrhea.

Intertrochanteric fracture in pregnancy- and lactation-associated osteoporosis.

Pregnancy- and lactation-associated osteoporosis (PLO) is a special form of osteoporosis, which is the result of multiple factors affecting bone metabolism. The manifestations of PLO include severe low back or hip pain in the third trimester of pregnancy and postpartum period, and some patients present with a decrease in height and even fragility fractures. We report here a 33-year-old patient who presented with a left intertrochanteric fracture after falling from standing height at 10 months postpartum. She was diagnosed with PLO because of a considerable decrease in bone mineral density. Our findings are discussed in relation to the literature. Early diagnosis and timely and appropriate therapy are particularly important for PLO. PLO should be considered in patients who complain of low back or transient hip pain during pregnancy and lactation. Discontinuing breastfeeding and supplementing calcium/vitamin D should be recommended after diagnosis of PLO is established.

Changes in Cold and Hot Syndrome and Gastrointestinal Bacterial Community Structure in Mice by Intervention with Food of Different Nature.

OBJECTIVE: To reveal the effect of foods with different natures on cold or hot syndrome and gastrointestinal bacterial community structure in mice. METHODS: Forty-five 6-week-old male ICR Kunming mice of clean grade were divided into 5 groups, 9 per group, including the control (CK), hot nature herbs (HM), Hong Qu glutinous rice wine (RW), tea rice wine (TW), and cold nature herbs (CM) groups. Distilled water or corresponding herbs were administered to mice (0.01 mL/g body weight) in the 5 groups by gastric infusion respectively, once daily for 28 d. Appearance, behavior, and serum biochemical indicators, including 5-hydroxytryptamine (5-HT), thyroid stimulating hormone (TSH), noradrenaline (NE), cyclic adenosine monophosphate (cAMP) and cyclic guanosine monophosphate (cGMP), the hot nature index, as well as the gastrointestinal bacterial community structure were analyzed in all groups after treatment. RESULTS: After supplementation for 28 d, CM and TW mice showed different degrees of cold syndrome, and HM and RW mice showed different degrees of hot syndrome. Compared with the HM and RW mice, the TSH, NE, cAMP levels and hot nature indices in the CM and TW mice were significantly decreased and 5-HT and cGMP levels were significantly increased (P<0.05). There was no obvious change in appearance or behavior in CK mice. Results of clustering analysis showed that the gastrointestinal bacterial community structures were highly similar in TW and CM mice as well as in RW and HM mice, and that they were from the same branch, respectively, when the distance was 0.02. The key microbes associated with cold syndrome were Lachnospiraceae uncultured, Lactococcus, etc., and the key microbes associated with hot syndrome were S24-7 norank, Ruminococcaceae uncultured, etc. CONCLUSION: The interventions with different nature foods could change cold or hot syndrome in mice, leading to changes in gastrointestinal bacterial community structure.

Research progress on anti-atherosclerosis effect and mechanism of flavonoids compounds mediated by macrophages / 中国中药杂志

Flavonoids are important active ingredients of traditional Chinese medicine, mainly with cardiovascular, anti-liver injury, antioxidant, antispasmodic, and estrogen-like effects. These compounds have obvious effects on the cardiovascular and cerebrovascular diseases. Macrophage-derived foam cells are the key medium in the process of atherosclerosis(AS). In plaque, allserum lipids, serum lipoproteins, and various pro-or anti-inflammatory stimulating factors, chemokines, and small bioactive molecules can significantly affect the macrophage phenotype and induce stronger pro-inflammatory or anti-inflammatory properties. Studies have shown that some flavonoids can be used for macrophages through different pathways and mechanisms, playing an anti-atherosclerosis effect to different degrees, including promotion of cholesterol efflux from macrophages, anti-foaming of macrophages, inhibition of secretion of inflammatory factors, and antioxidant modified low density lipoprotein(ox-LDL)-induced apoptosis of macrophages. Related gene regulation inclu-ded ATP-binding cassette transporter A1(ABCA1), ATP-binding cassette transporter G1(ABCG1), Toll-like receptor(TLR), and scavenger receptor(SR). In this article, we would review the recent research progress of flavonoids on anti-atherosclerosis effect me-diated by macrophage. It is expected to provide new treatment strategies for AS-related cardiovascular and cerebrovascular diseases, and provide research ideas and development directions for the use of related natural medicines and design of new products.

Objective:To observe the effect of modified Tongqiao Huoxuetang on circulating blood flow and wall shear stress of vertebrobasilar dolichoectasia (VBD) due to blood stasis and channel blockage. Method:A total of 97 patients admitted in our department from October 2017 to August 2019 were collected. The traditional Chinese medicine (TCM) syndromes were consistent with blood stasis and channel blockage, and diagnosed as VBD by magnetic resonance angiography (MRA). The patients were divided into experimental group (48 cases) and control group (49 cases). Control group was given basic therapy and placebo of TCM, while treatment group was given basic therapy and modified Tongqiao Huoxuetang for 30 days. The degree of relief of vertigo symptoms, vertigo symptom scale (VSS), activity balance confidence (ABC), transcranial doppler (TCD) bilateral vertebral artery and basilar artery blood flow velocity [systolic blood flow velocity (Vs), mean blood flow velocity (Vm), diastolic blood flow velocity (Vd)], mean blood flow differences between (MFV), pulsatility index, resistance index (RI), and wall shear force (WSS) were observed before and after treatment. Result:Compared with control group before treatment, the score of ABC scale in control group after treatment was markedly higher, while the score of VSS was significantly lower (P<0.05). However, there was no statistical significance in the score of vertigo symptom. Compared with treatment group before treatment, the symptom grade of vertigo degree and the score of VSS in treatment group after treatment were substantially lower, while the score of ABC scale was significantly higher (P<0.05). Compared with control group, the score of vertigo degree symptoms and VSS in treatment group were markedly lower, while the score of ABC scale was significantly higher (P<0.05). Compared with control group before treatment, Vm, MFV and WSS of bilateral vertebral artery in control group after treatment were substantially higher, while RI was significantly lower (P<0.05). However, there were no statistical significances in Vs, Vd and PI in control group before and after treatment. Compared with treatment group, Vs, Vd, Vm, MFV and WSS of bilateral vertebral artery in treatment group after treatment were markedly higher, while RI was significantly lower (P<0.05). However, there was no statistical significance in PI of experimental group before and after treatment. Compared with control group after treatment, Vs, Vd, Vm, MFV and WSS of bilateral vertebral artery in treatment group after treatment were substantially higher, while there was no statistical significance in PI and RI. Before and after treatment, there were similar changes in blood flow parameters of the basilar artery and bilateral vertebral artery. Conclusion:Modified Tongqiao Huoxuetang could improve the clinical symptoms of dizziness or vertigo in patients of VBD due to blood stasis and channel blockage, and the mechanism might be related to the improvement of post-circulation hemodynamics by Tongqiao Huoxuetang.

Based on the results of network analysis， 24 male SPF ACR mice were randomly divided into control group， total Ginsenoside Ginseng Root group （0.08 g·kg-1） and Notoginseng total Saponins group （0.08 g·kg-1）. The corresponding drugs were given for 3 weeks. The expressions of core genes in muscle tissue were detected by real-time fluorescence quantitative PCR. Result:The 20 active components and 181 drug targets were screened from TCMSP. 33 intersecting genes of diseases and drugs were obtained when compared with GeneCards and OMIM comprehensive database using R software. 10 core genes including aryl hydrocarbon receptor （AHR）， androgen receptor （AR）， glutathione S-transferase P1 （GSTP1）， cysteine proteinase-3（Caspase-3）， cytochrome p450 enzyme 3A4 （CYP3A4）， intercellular adhesion molecule 1 （ICAM1） and nuclear factor kappa B inhibitor alpha （NFKBIA） were screened out by the algorithm of MCC. Total Ginsenoside Ginseng Root and Notoginseng total Saponins had no significant effect on GSTP1 and ICAM1 genes， but they could significantly inhibit the expressions of AHR， CYP3A4， Caspase-3， NFKBIA and AR （P<0.05，P<0.01）， and there were no significant difference in anti-fatigue effect between total Ginsenoside Ginseng Root and Notoginseng total Saponins groups. Conclusion:The mechanism of anti-fatigue of Ginseng Radix et Rhizoma and Notoginseng Radix et Rhizoma may be related to the regulation of AHR， CYP3A4 and Caspase-3 genes， and there is no significant difference in their anti-fatigue effects， through the analysis of network and experimental verification.

Analysis on Mechanisms of Modified Guipitang in Treatment of Yin-Fire Insomnia with Anxiety Based on Network Pharmacology / 中国实验方剂学杂志

Objective:To explore the mechanism of modified Guipitang in the treatment of Yin-Fire insomnia with anxiety with the help of network pharmacological analysis technology. Method:Traditional Chinese Medicine Systems Pharmacology (TCMSP) was used to screen the main components and target genes of modified Guipitang. GeneCards and Online Mendelian Inheritance in Man (OMIM) were used to establish the target gene sets of insomnia and anxiety. STRING 11.0 software was used to analyze the interaction between the overlapping genes, and Cytoscape_3.6.1 software analysis and Matthews correlation coefficient (MCC) algorithm were used to screen the core genes. Based on the results of network analysis, 48 SD female rats were randomly divided into blank control group, model group, eszopiclone tablets group (0.2 mg·kg-1·d-1), modified Guipitang low，medium，and high-dose groups (0.31，1.25，5 g·kg-1·d-1). The model of insomnia with anxiety was established by intraperitoneal injection of Para-chlorophenylalanine (PCPA) and these rats were treated with corresponding drugs for 7 days. Then the frequency, time and distance of the activities were observed in the experiment of autonomic activity. Real-time quantitative polymerase chain reaction (PCR) was used to detect the mRNA expressions of proactivated protein kinase 8 (MAPK8), RAC-alpha serine/threonine protein kinase (Akt1), mitogen-activated protein kinase 3 (MAPK3) and interleukin-6 (IL-6) in rat hippocampus. Result:A total of 228 active compounds were screened from TCMSP database and 181 intersecting genes of diseases and drugs were obtained by comparing with GeneCards and OMIM comprehensive database. 9 core genes, including MAPK3, MAPK8, Akt1 and IL-6 were identified by STRING software and MCC algorithm. Animal experiments showed that the number of activity times, time and distance of modified Guipitang in high and medium dose groups were significantly lower than those in the model group. The high and middle dose groups of modified Guipitang could significantly inhibit the mRNA expression of MAPK3, MAPK8, Akt1 and IL-6 in hippocampus（P<0.01）, while the low dose group had no significant effect. Conclusion:The mechanism of modified Guipitang in treating Yin-fire insomnia with anxiety may be related to the regulation of MAPK3, MAPK8, Akt1 and IL-6 genes.
