The Development of Chinese Herbal Formulae for Non-severe COVID-19 Based on Artificial Intelligence Technology and Investigation of Its Action Mechanisms / 中医杂志

ObjectiveTo develop traditional Chinese medicine （TCM） formulae for the treatment of nonsevere coronavirus disease 2019 （COVID-19） and to explore its anti-inflammatory mechanism. MethodsThe dysregulated signaling pathways were determined in macrophages from bronchoalveolar lavage fluid of COVID-19 patients and in lung epithelial cells infected with SARS-CoV-2 in vitro based on transcriptome analysis. A total of 102 TCM formulae for the clinical treatment of nonsevere COVID-19 were collected through literature. The pathway-reversing rates of these formulae in macrophages and lung epithelial cells were evaluated based on signature signaling pathways， and the basic formula was determined in conjunction with TCM theory. The commonly used Chinese materia medica for nonsevere COVID-19 were summarized from the 102 TCM formulae as abovementioned. And together with the screening results from the Pharmacopoeia of the People's Republic of China， a “Chinese materia medica pool” was esta-blished for the development of TCM formulae for COVID-19. The regulatory effects of each herb on signaling pathways were obtained based on targeted transcriptome analysis. Oriented at reversing dysregulated signaling pathways of COVID-19， the calculation was carried out， and the artificial intelligent methods for compositing formulae， that are exhaustive method and parallel computing， were used to obtain candidate compound formulas. Finally， with reference to professional experience， an innovative formula for the treatment of nonsevere COVID-19 was developed. The ethanol extract of the formula was evaluated for its anti-inflammatory effects by detecting the mRNA expression of interleukin 1b （Il1b）， C-X-C motif chemokine ligand 2 （Cxcl2）， C-X-C motif chemokine ligand 10 （Cxcl10）， C-C motif chemokine ligand 2 （Ccl2）， nitric oxide synthase 2 （Nos2）， and prostaglandin-endoperoxide synthase 2 （Ptgs2） using reverse transcription-quantitative polymerase chain reaction （RT-qPCR） in RAW264.7 cells treated with lipopolysaccharide （LPS）. ResultsIn macrophages and lung epithelial cells， 34 dysregulated signaling pathways associated with COVID-19 were identified respectively. The effects of the 102 formulae for clinical treatment of nonsevere COVID-19 were evaluated based on the dysregulated signaling pathways and targeted transcriptome， and the result showed that Yinqiao Powder and Pingwei Powder （银翘散合平胃散， YQPWP） ranked first， reversing 91.18% of the dysregulated signaling pathways in macrophages and 100% of the dysregulated signaling pathways in lung epithelial cells. Additionally， YQPWP had the function of scattering wind and clearing heat， resolving toxins and removing dampness in accordance with the pathogenesis of wind-heat with dampness in COVID-19. It was selected as the basic formula， and was further modified and optimized to develop an innovative fomula Qiaobang Zhupi Yin （翘蒡术皮饮， QBZPY） based on expert experience and artificial intelligence in composing formulae. QBZPY can reverse all the dysregulated signaling pathways associated with COVID-19 in macrophages and lung epithelial cells， with the reversing rates of 100%. The chief medicinal of QBZPY， including Lianqiao （Fructus Forsythiae）， Xixiancao （Herba Siegesbeckiae） and Niubangzi （Fructus Arctii）， can down-regulate multiple signaling pathways related with virus infection， immune response， and epithelial damage. RT-qPCR results indicated that compared with the model group， the QBZPY group down-regulated the mRNA expression of Il1b， tumor necrosis factor （Tnf）， Cxcl2， Cxcl10， Ccl2， Nos2 and Ptgs2 induced by LPS in RAW264.7 cells （P＜0.05 or P＜0.01）. ConclusionBased on targeted transcriptome analysis， expert experience in TCM and artificial intelligence， QBZPY has been developed for the treatment of nonsevere COVID-19. The ethanol extract of QBZPY has been found to inhibit mRNA expression of several pro-inflammatory genes in a cellular inflammation model.

The effects of natural polysaccharide supramolecular hydrogel on bacteriostatic activity and biofilm clearance of berberine / 药学学报

Taking berberine (BBR) as an example, to study whether the supramolecular hydrogel formed by berberine and lotus root starch (Nelumbo nucifera Gaertn; LRS), a natural polysaccharide, affects the inhibition to Staphylococcus aureus and the ability of biofilm clearance. The chemical structure and rheological properties of BBR@LRS gel were characterized by infrared spectroscopy and rheometer. The in vitro release of supramolecular hydrogel was observed at pH = 1.2 and pH = 7.4. Broth dilution method and biofilm clearence experiment were used to observe the bacteriostasis and biofilm clearance respectively. Cytotoxicity test and in vitro hemolysis test were used to evaluate the biosafety preliminarily. The results showed that the LRS polysaccharide hydrogel could encapsulate BBR, and there was an interaction between them. The BBR@LRS gel had good rheological properties and biosafety, and played a role in solubility enhancement and slow release of BBR, which was stronger than BBR in inhibiting the growth of Staphylococcus aureus and clearing biofilm. This study provides reference for the effect of natural polysaccharide supramolecular hydrogels on biological functions of active components of traditional Chinese medicine.

Effect of acupotomy intervention on the morphology and ultrastructure of rectus femoris muscle in rabbits with knee osteoarthritis / 中国骨伤

OBJECTIVE@#To observe the effect of acupotomy on the morphology and ultrastructure of rectus femoris muscle in rabbits with knee osteoarthritis and to reveal the possible therapeutic mechanism involved in the effect of acupotomology on the treatment of knee osteoarthritis(KOA).@*METHODS@#Twenty-four male New Zealand rabbits aged 6 months and weighed (2.0±0.5) kg were randomly divided into blank group, model group and acupotomy group, 8 rabbits in each group. KOA model was established by modified Videman method with left hind limb extended plaster immobility for 6 weeks. In acupotomy group, the transfascial focal points of quadriceps femoris muscle were released by acupotomy under the guidance of Jingjin theory for 4 times and once a week, and the treatment points include Hedingci, Binwaixia, Binneixia. Blank group and model group were fed normally without intervention. One week after the end of the intervention, the pennation angle(PA), muscle thickness(MT), cross-sectional area(CSA) and strain ratio(SR) of rectus femoris were measured by ultrasound. HE staining was used to observe the changes of the tissue morphology, the number of muscle fibers and the average area of muscle fibers. The myofibril of rectus femoris, sarcomere and myofilament were observed by transmission electron microscope.@*RESULTS@#The PA of rectus femoris muscle in the blank group was (9.05±0.21)°. The MT was(1.09±0.09) cm and the CSA was(1.30±0.01) cm2. The PA of rectus femoris muscle in the model group was (3.06±0.15)°. The MT was (0.71±0.02) cm and the CSA was(0.77±0.02) cm2. The PA of rectus femoris muscle in the acupotomy group was (6.94±0.28)°. The MT was (0.80±0.05) cm and the CSA was(0.94±0.03) cm2. The muscle PA, MT and CSA of rectus femoris in the model group were significantly smaller than those in the blank group (P<0.05). Those in acupotomy group were significantly increased compared with those in model group (P<0.05). The SR of rectus femoris muscle was 1.19±0.02 in the blank group, 3.50±0.05 in the model group and 1.99±0.07 in the acupotomy group. The elastic SR of the model group was significantly higher than that of the blank group (P<0.05). These in acupotomy group was significantly lower than that in model group(P<0.05). The results of HE staining showed:in blank group, the fascicles of rectus femoris were arranged neatly, the number of beam of muscle fibers within the fixed visual field was 94.38±3.50 and the average CSA was(0.75±0.22) mm2. In model group, the fascicles of rectus femoris with different sizes were disorganized with a small amount of inflammatory cell infiltration, the number of beam of muscle fibers within the fixed visual field was 196.63±2.62 and the average CSA was(0.26±0.03) mm2. Compared to the blank group, a significant increase in the number of muscle fibers in the fixed field in the model group (P<0.05) and the average CSA decreased significantly(P<0.05). In acupotomy group, the rectus femoris fascicles in the acupotomy group tended to be arranged in a more orderly manner, with the inflammatory cells decreased, the number of beam of muscle fibers within the fixed visual field was 132.88±4.61 and the average CSA was(0.70±0.07) mm2. Compared to the model group, a significant decrease in the number of muscle fibers in the fixed field in the model group(P<0.05) and the average CSA increased significantly(P<0.05). The results of transmission electron microscope showed:compared with the blank group, the overall arrangement of the myofibrils of the rectus femoris in the model group was less structured. There was fracture between the muscle fibers and the sarcomere, the myofilaments were disordered, and the fracture of the Z line was discontinuous. Compared with the model group, the myofibrillar texture of rectus femoris in acupotomy group was clearer, and the Z line was more continuous.@*CONCLUSION@#Based on the jingjin theory, the release of quadriceps femoris by acupotomy can effectively improve the morphology and structure of rectus femoris, and promote the repair and reconstruction of chronic skeletal muscle injury in rabbits with KOA, which may be one of the mechanisms of acupotomy in the treatment of KOA.

Targeting of inflammatory pathways with R2CHOP in high-risk DLBCL.

Diffuse large B-cell lymphoma (DLBCL) is the most common lymphoma, and front line therapies have not improved overall outcomes since the advent of immunochemotherapy. By pairing DNA and gene expression data with clinical response data, we identified a high-risk subset of non-GCB DLBCL patients characterized by genomic alterations and expression signatures capable of sustaining an inflammatory environment. These mutational alterations (PIM1, SPEN, and MYD88 [L265P]) and expression signatures (NF-κB, IRF4, and JAK-STAT engagement) were associated with proliferative signaling, and were found to be enriched in patients treated with RCHOP that experienced unfavorable outcomes. However, patients with these high-risk mutations had more favorable outcomes when the immunomodulatory agent lenalidomide was added to RCHOP (R2CHOP). We are the first to report the genomic validation of a high-risk phenotype with a preferential response towards R2CHOP therapy in non-GCB DLBCL patients. These conclusions could be translated to a clinical setting to identify the ~38% of non-GCB patients that could be considered high-risk, and would benefit from alternative therapies to standard RCHOP based on personalized genomic data.

In vitro inhibition by 79 herb injectables of nine human cytochrome P450 isoenzymes: a systematic evaluation of herb-drug interactions / 药学学报

Seventy-nine injectable herb extractions have been approved by the Chinese Food and Drug Administration (CFDA) and are frequently administered intravenously for various diseases. Unfortunately, herb-drug interactions are under-investigated and sometimes overlooked in the clinic. In the present investigation the in vitro inhibition of 9 drug metabolizing enzymes including CYP1A, CYP2A6, CYP2B6, CYP2C8, CYP2C9, CYP2C19, CYP2D6, CYP2E1, and CYP3A was assessed using an appropriate probe substrate for each enzyme with human liver microsomes. Metabolite formation was quantified using a validated and sensitive high-performance liquid chromatography-tandem mass spectrometry (LC-MS/MS) assay. The IC50 of each herb extract was estimated using a concentration range from 5% to 0.5%, and the time-dependent inhibition of the nine CYP450 isoenzymes was also determined. Of the 79 approved iv herb injectables, 37 inhibited CYP1A, 24 inhibited CYP2A6, 41 inhibited CYP2B6, 36 inhibited CYP2C8, 31 inhibited CYP2C9, 41 inhibited CYP2C19, 13 inhibited CYP2D6, 25 inhibited CYP2E1, and 42 inhibited CYP3A with 50% or greater inhibition at a test concentration of 5% (v/v). IC50 differences were noted between pre-incubation or co-incubation assays with HLM for 30 min, with the time-dependent inhibitory (TDI) effects were observed with 2 injectables on CYP1A, 5 injectables on CYP2A6, 5 injectables on CYP2B6, 6 injectables on CYP2C8, 1 injectable on CYP2D6 and 6 injectables on CYP3A. Collectively, the results demonstrate that potential herb-drug interactions (HDIs) can occur with the concomitant use of herb injectables and prescription drugs that are cleared by CYP450 enzymes, and further investigation is warrant for the clinical relevance of these interactions.

Objective:To analyze the general situation and traditional Chinese medicine (TCM) syndrome characteristics in patients with coronavirus disease-2019（COVID-19） in Anhui province, and to provide a basis for clinical diagnosis and treatment. Method:The 144 cases of COVID-19 patients in Anhui province were collected from designated hospitals by means of multi-center cross-sectional epidemiological survey. The TCM syndrome information collection table of patients with novel coronavirus pneumonia was created to collect the general data, etiology and pathogenesis, pulse and signs, syndrome type and frequency statistics of the patients, and then summarize and analyze the main symptoms and syndrome distribution characteristics of patients with novel coronavirus pneumonia. Result:The mean age of 144 patients with COVID-19 infection was （43.54±15.91） years old, and the number of males was larger than the number of females (9/7). The age distribution and gender difference of the patients were statistically significant (P<0.05). 36.11%（52/144） of the patients had a history of travel/residence in Wuhan/Hubei province, and 63.89% (92/144) of the patients had a history of close contact with the confirmed patients. The main clinical manifestations included fever, cough, diarrhea, fatigue and poor tolerance. Light red tongue and red tongue were dominant in tongue quality, with mainly greasy coating, slippery pulse, rapid pulse and soft pulse were the main types of pulse. The main types of syndrome differentiation were the common type (76.38%, 110/144), most of which were demonstrated as dampness obstructing the lung and spleen (56.25%, 81/144). There was no significant difference in gender composition and age distribution between two groups. Conclusion:The pathogenesis of COVID-19 patients in Anhui province is closely related to the lung and spleen, and the dampness caused by pathogen of the epidemic virus is the main pathological factor of disease, which is in line with characteristics of dampness epidemic in TCM, also can see concurrently "heat, poison, stasis" for a characteristic.

Animal Model of Qi Deficiency and Blood Stasis Syndrome / 中国实验方剂学杂志

The study of traditional Chinese medicine(TCM) syndrome model started late but developed rapidly. In recent years, with the deepening of the study of TCM diseases and prescriptions, to develop the modernization of TCM, the study of TCM syndrome model has been required to be more specific and went deeper. Qi deficiency and blood stasis syndrome, as a common clinical syndrome type, often occurs in cardiovascular and cerebrovascular diseases, digestive system diseases, chronic kidney disease, cancer and other diseases. With the increase in the aging of population in China, the research on Qi deficiency and blood stasis syndrome has become a hot topic in the field of TCM due to the physical characteristics of the elderly people with multiple Qi deficiency and blood stasis. The animal models of Qi deficiency and blood stasis syndrome established in recent years were classified into pathological model, etiological model and combined disease and syndrome model. By observing the macroscopical representation, limb behavior and hemorheology of experimental animals in line with the theory of TCM, this paper evaluates the method of modeling, and provides ideas and reference for the method of modeling for Qi-deficiency and blood-stasis syndrome. The research on the model of Qi-deficiency and blood-stasis syndrome should follow the thought of cause-pulse-syndrome-treatment, namely etiology-external manifestation-pathological mechanism-syndrome differentiation and treatment, and combine the study on the TCM syndrome model with modern science, so as to standardize the development of modeling methods and build relatively improved animal models of Qi deficiency and blood stasis, and provide model support for exploring the pathogenesis of Qi deficiency and blood stasis syndrome and new treatment ideas in the future.

Advances in Studies on Chinese Materia Medica for Treatment of Sepsis Based on NF-κB Signal Pathway / 中国实验方剂学杂志

Sepsis is a kind of systemic inflammatroy response syndrome (SIRS) induced by severe infection,operation,and trauma,with high mortality rate,treatment cost,and high consumption of medical resources.It has caused a great burden to the medical industry and even the national economy.Therefore,it is urgent to find effective treatment methods for sepsis.At present,the sepsis has been treated with certain drugs pointing at its pathogenesis,such as antibiotics,glucocorticoids,and vasoactive drugs.,but the therapeutic effect is not ideal,with many side effects,poor prognosis,and high clinical mortality.Based on the overall macro-dialectical thinking mode,and with the unique effect and low side effect,traditional Chinese medicine (TCM) has attracted the attention from researchers and clinicians around the world for treatment of sepsis.In recent years,some traditional Chinese medicine prescriptions,Chinese patent medicines,single Chinese medicines and active ingredients are increasingly used as new drugs to prevent and treat sepsis.Such treatment methods have been widely recognized and have reduced the mortality and inflammatory indexes of patients to a certain extent,playing an important role in the prevention and treatment of sepsis.In this paper,the actions of nuclear factor kappa B (NF-κB) signal pathway in sepsis as well as the advances in research of NF-κB signal pathway-related proteins in Chinese medicine for sepsis were reviewed.

Signal Pathways Relating to Prevention and Treatment of Airway Remodeling in Chronic Obstructive Pulmonary Disease with Traditional Chinese Medicine / 中国实验方剂学杂志

Chronic obstructive pulmonary disease (COPD) is a common respiratory disease with a high morbidity, disability and mortality. At the same time, COPD is always accompanied by pulmonary hypertension, pulmonary fibrosis, chronic pulmonary heart disease, right heart failure and other common serious complications. All of these cause serious financial burden for the family of patients. Airway remodeling plays an important role in the pathogenesis of COPD. It is the progressive development of airflow restriction that induces the main symptoms of COPD, such as cough, asthma and depression. Therefore, it is of great research value to explore the intervention of traditional Chinese medicine(TCM) in the development of COPD by alleviating airway remodeling. Studies have shown that multiple signaling pathways can induce progressive airway remodeling, and the therapeutic effect of TCM has been frequently confirmed by experimental studies. TCM often has a therapeutic effect on COPD through multi-target and multi-channel mediation. This paper mainly includes five signaling pathways that traditional Chinese medicine can intervene COPD airway remodeling, namely matrix metalloproteinases (MMPs)/tissue inhibitors of metalloproteinase (TIMPs), transforming growth factor (TGF)-beta 1/Smads, RhoA/Rho-associated kinase (ROCK), vascular endothelial growth factor (VEGF)/b-fibroblast growth factor (b-FGF) and nuclear factor (NF)-κB. This paper briefly reviews the research progress of these five signaling pathways, and discusses other signaling pathways that may be involved, in order to provide reference and ideas for future experimental research.

Method A total of 180 hemiplegia patients were randomized into 3 groups, 60 cases in balance acupuncture group, 60 cases in ordinary acupuncture group, and 60 cases in basic control group. After 1-month treatment and 3 months after the treatment, the motor function (Fugl-Meyer Assessment, FMA), balance function (Berg Balance Scale, BBS; Timed Up and Go Test, TUGT), and activities of daily living (ADL) (Barthel Index, BI) were observed.Result After 1-month treatment and 3 months after the treatment, limb function, balance ability and ADL were significantly different from those before the treatment in balance acupuncture group (P<0.01); after 1-month treatment, limb function in balance acupuncture group was significantly different from that in basic control group (P<0.05), and the differences were more statistically significant in comparing the rest indexes between the two groups (P<0.01); there were significant differences between ordinary acupuncture group and basic control group (P<0.05). Three months after the treatment, there was a significant difference in comparing balance function between balance acupuncture group and basic control group (P<0.05), and the differences were more statistically significant in comparing the rest indexes between the two groups (P<0.01), there was no significant difference in comparing balance function between ordinary acupuncture group and basic control group (P>0.05).Conclusion In combination with basic treatment, balance acupuncture works better than ordinary acupuncture and basic control in improving limb function, ADL and balance function of hemiplegia patients.

Genome-wide association study on susceptibility genes associated with yang-deficiency constitution: A small sample case-control study / 中国结合医学杂志

<p><b>OBJECTIVE</b>To explore susceptibility genes associated with yang-deficiency constitution using single nucleotide polymorphism (SNP) genotyping.</p><p><b>METHODS</b>Based on an epidemiological survey, 30 volunteers with yang-deficiency constitution and 30 volunteers with a balanced constitution were included according to the Classification and Determination Standards of Constitutions in Traditional Chinese Medicine. Peripheral blood was collected and DNA was extracted from white blood cells. A genome-wide association study (GWAS) was conducted by SNP 6.0 genotyping at the Beijing CapitalBio Corporation Ltd. A minimum association P-value (Fisher's exact value) of less than 10(-4) in the allele, genotype, dominant, and recessive models served as the standard for significant association of SNP with yang-deficiency constitution.</p><p><b>RESULTS</b>Among the four genetic models, a total of 42 SNPs were significantly associated with yang-deficiency constitution (Fisher's exact P-values P<10(-4)). These SNPs were adjacent to more than 20 genes, including RGS6, mGluR5, GAPDHL19, and IKZF1.</p><p><b>CONCLUSION</b>Yang-deficiency constitution exhibits the characteristics of polygenic inheritance. This pilot study suggests that the polymorphisms in RGS6, mGluR5, GAPDHL19, and IKZF1 are associated with changes in cyclic adenosine monophosphate and cyclic guanosine monophosphate levels, memory, metabolic energy status, and immune function, respectively in people with yang-deficiency constitution.</p>

Correlation Study on Chinese Medical Syndrome Types of Chronic Atrophic Gastritis Patients, Hp, and IL-1β Polymorphism / 中国中西医结合杂志

<p><b>OBJECTIVE</b>To explore the correlation between Chinese medical (CM) syndrome types of chronic atrophic gastritis (CAG) patients and Helicobacter pylori (Hp) infection, polymorphisms of IL-1B, and IL-1β.</p><p><b>METHODS</b>Totally 192 CAG patients and 202 healthy subjects (as the healthy control group) were recruited in this case-control study. The Hp infection was tested by 13C-urea breath test and colloidal gold-labeled assay (GICA). The concentration of peripheral blood IL-1β was measured by ELISA. The polymorphisms of IL-1B gene in the promoter region were analyzed using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP).</p><p><b>RESULTS</b>Pi-Wei weakness syndrome (PWWS) was dominant in CAG patients (31.77%, 61/192 cases). The Hp infection ratio in CAG patients was 53.65% (103/192 cases), of which, Pi-Wei damp-heat syndrome(PWDHS, 64.86%, 24/37 cases) and Gan-Wei disharmony syndrome (GWDS, 66.67%, 24/36 cases) were dominant. Compared with the health control group, the plasma concentration of IL-1β was obviously elevated in CAG patients with PWDHS, GWDS, and static blood obstructing collaterals syndrome (SBOCS) (all P < 0.05). Additionally, there was no difference in the distribution of polymorphisms in the promoter region of IL-1 B gene between the CAG patients and the healthy control group (P > 0.05).</p><p><b>CONCLUSIONS</b>The incidence risk of CAG was not associated with IL-1B polymorphism. But CM syndrome types of CAG patients was associated with Hp infection and peripheral blood IL-1β levels.</p>
