Objective To investigate the effect of cinobufacini on inhibiting colorectal cancer metastasis by regula-ting the polarization of M2 macrophages.Methods THP-1 was induced into M0 type macrophages.The condi-tioned medium of HCT116 cells was collected to stimulate M0 type macrophages.The polarization of M2 type mac-rophages was observed by flow cytometry,real-time quantitative PCR and ELISA experiments.The conditioned me-dium of M0 type macrophages and HCT116-Mφ cells was collected to stimulate HCT116 cells.The ability of migra-tion and invasion was observed by wound healing assay and Transwell assay.The effect of cinobufacini on the via-bility of HCT116 cells was detected by CCK-8 assay.The conditioned medium of HCT116 and HCT116+cinobufa-cini was collected to stimulate M0 type macrophages.The polarization of M2 type macrophages was observed by flow cytometry,real-time quantitative PCR and ELISA experiments.The conditioned media of HCT116-Mφ cells and(HCT116+cinobufacini)-Mφ cells were collected to stimulate HCT116 cells.The changes of migration and inva-sion ability were observed by wound healing assay and Transwell assay.Results After stimulation of M0 type mac-rophages in HCT116 cell conditioned medium,the morphology of M0 macrophages turned into fusiform cells,the proportion of CD11b+CD206+cells increased,and the expression of M2 macrophage markers IL-10 and TGF-β in-creased.The migration and invasion ability of HCT116 cells were significantly enhanced after stimulation in the conditioned medium of HCT1 16-Mφ cells.After the addition of cinobufacini,not only the polarization proportion of M2 macrophages decreased,but also the metastatic effect mediated by M2 macrophages was inhibited.Conclusion HCT116 cells can induce the polarization of M2 macrophages,while cinobufacini can inhibit the tumor metastasis mediated by M2 macrophages by inhibiting the polarization of M2 macrophages.

Inhibition of M2-type macrophage-mediated migration and epithelial mesenchymal transition in colorectal cancer by bufalin / 安徽医科大学学报

Objective To investigate the role of bufalin(BU)in inhibiting M2-type macrophage-mediated colorec-tal cancer metastasis.Methods Human acute leukemia mononuclear cells(THP-1)were differentiated into M0 macrophages using phorbol ester induction(PMA)for 48 hours.The M0 macrophages were then treated with IL-4 and IL-13 medium.Surface markers and morphological changes were observed through ELISA,morphology,and RT-qPCR experiments.RT-PCR and ELISA experiments were conducted to detect the surface markers TGF-β and IL-10 of M2 macrophages.The secretion level of IL-6 in the supernatant of M2 macrophages and colorectal cancer cells HCT116 was compared using ELISA.Additionally,the effect of conditioned medium on colorectal cancer cell HCT116 was assessed through Transwell,Wound healing,RT-qPCR,and Western blot experiments.Subsequent-ly,bufalin was added to the conditioned medium and the changes in AKT/PI3K protein,migration,and epithelial-mesenchymal transition ability in HCT116 were observed using Western blot,Transwell,Wound healing and RT-qPCR experiments.Results THP-1 were successfully differentiated into M2 macrophages.The activation of AKT/PI3K protein in HCT116 cells was induced by the secretion of IL-6 from M2 macrophages,which in turn promoted the migration and epithelial-mesenchymal transition ability of the HCT116 cells.The migration and epithelial-mes-enchymal transition mediated by M2 macrophages in HCT116 cells were effectively inhibited by Bufalin.Conclu-sion The release of IL-6 from M2 macrophages activates the AKT/PI3K signaling pathway in colorectal cancer cells,thereby promoting their migration and epithelial-mesenchymal transition capacity.Moreover,bufalin exhibits inhibitory effects on this effect.

Comparison of accuracy of intraocular lens calculation formulas in cataract eyes with prior radial keratotomy and axial length longer than 28mm / 国际眼科杂志(Guoji Yanke Zazhi)

AIM: To compare the accuracy of different intraocular lens(IOL)calculation formulas in cataract patients with axial length longer than 28mm and a history of radial keratotomy(RK).METHODS: Retrospective study. The medical records of 19 cataract patients(29 eyes)after RK and with axial length longer than 28mm who underwent cataract surgery from January 2011 to July 2020 in Beijing Tongren Hospital were analyzed. The absolute error(AE)of the difference among three different formulas was calculated. AE refers to the absolute value between the actual spherical equivalent after cataract surgery and the spherical equivalent predicted by the IOL formula. The AE values of the three formulas and the percentages of eyes with AE≤0.5, 0.75, 1.0, and 2.0D were calculated and compared.RESULTS: The AE values of the three formulas were significantly different(χ2=8.759, P=0.013). The Barrett True-K formula had the smallest median AE, which was only 0.62(0.20, 1.15)D, followed by the Haigis formula 0.76(0.34, 1.26)D, and the Holladay 1(D-K)formula had the largest 1.01(0.49, 1.62)D. The percentages of affected eyes with AE ≤0.5, 0.75, 1.0, and 2.0D for the Barrett True-K formula were 48%, 59%, 69%, and 93%, which were equal to or higher than the other two formulas.CONCLUSION: The Barrett True-K formula is more recommended among the three formulas for cataract patients after RK and with axial length longer than 28 mm.

Analysis of therapeutic mechanism of Liushen Wan against colitis-associated colorectal cancer based on network pharmacology and validation in mice / 南方医科大学学报

OBJECTIVE@#To explore the therapeutic mechanism of Liushen Wan (LSW) against colitis-associated colorectal cancer (CAC) by network pharmacology.@*METHODS@#TCMSP, BATMAN-TCM, CNKI, PubMed, Genecards, OMIM, and TTD databases were used to obtain the related targets of LSW and CAC. The common targets of LSW and CAC were obtained using Venny online website. The PPI network was constructed using Cytoscape 3.8.2 to screen the core targets of LSW in the treatment of CAC. GO and KEGG enrichment analysis were conducted using DAVID database. The therapeutic effect of LSW on CAC was evaluated in a C57BL/6J mouse model of AOM/DSS-induced CAC by observing the changes in body weight, disease activity index, colon length, and size and number of the tumor. HE staining and RT-qPCR were used to analyze the effect of LSW on inflammatory mediators. Immunohistochemistry and TUNEL staining were used to evaluate the effect of LSW on the proliferation and apoptosis of AOM/DSS-treated colon tumor cells. Immunohistochemistry and Western blotting were used to detect the effects of LSW on the expression of TLR4 proteins in CAC mice.@*RESULTS@#Network pharmacology analysis identified 69 common targets of LSW and CAC, and 33 hub targets were screened in the PPI network. KEGG pathway enrichment analysis suggested that the effect of LSW on CAC was mediated by the Toll-like receptor signaling pathway. In the mouse model of AOM/DSS-induced CAC, LSW significantly inhibited colitis-associated tumorigenesis, reduced tumor number and tumor load (P < 0.05), obviously improved histopathological changes in the colon, downregulated the mRNA levels of proinflammatory cytokines, and inhibited the proliferation (P < 0.01) and promoted apoptosis of colon tumor cells (P < 0.001). LSW also significantly decreased TLR4 protein expression in the colon tissue (P < 0.05).@*CONCLUSION@#LSW can inhibit CAC in mice possibly by regulating the expression of TLR4 to reduce intestinal inflammation, inhibit colon tumor cell proliferation and promote their apoptosis.

Objective: To analyze the clinical characteristics, treatment response, and prognosis of newly diagnosed symptomatic multiple myeloma (MM) patients with systemic light chain amyloidosis (AL) . Methods: The clinical data of 160 patients with newly diagnosed MM treated at the First Affiliated Hospital of Soochow University from January 1, 2017 to October 31, 2018, were retrospectively analyzed. According to the histopathological biopsy results of bone marrow, skin, and other tissues, the patients were divided into two groups according to whether amyloidosis was combined or not, namely, the MM+AL group and the MM group. The clinical characteristics and treatment responses of the two groups were compared. Results: Among the 160 patients with newly diagnosed MM, there were 42 cases in the MM+AL group and 118 cases in the MM group. In terms of clinical features, the involved light chain and non-involved light chain (dFLC) in the MM+AL group was significantly higher than that in the MM group (P=0.039) . After induction treatment, the MM+AL group had a higher overall response rate (85.7%vs 79.7%, P<0.05) and higher excellent partial response (76.2%vs 55.1%, P<0.05) . After a median follow-up of 26 (0.25-41) months, there was no significant difference in the progression free survival and overall survival (OS) between the two groups (P>0.05) . The OS of patients in autologous hematopoietic stem cell transplantation group was better than that in non transplantation group (P<0.05) .The prognosis of patients with cardiac involvement in the MM+AL group was significantly worse than that in the MM group and MM+AL group without cardiac involvement (P<0.001) , with a median OS of only 13 months. Conclusion: The differential diagnosis between the MM+AL and MM groups requires histopathology, particularly for patients with significantly increased dFLC. The overall remission rate of patients in MM+AL group after 4 courses of induction chemotherapy was higher than that in MM group. The prognosis of patients with cardiac involvement in MM+AL group was poor.

Chinese Expert's Perspectives on Andrological Diseases Responding Specifically to Traditional Chinese Medicine / 中国实验方剂学杂志

In recent years， the incidence rate of andrological diseases has shown a significant growth trend. Considering the unavailability of a perfect theoretical system for andrology in traditional Chinese medicine （TCM） and the complex pathogenesis despite of the limited types of andrological diseases， it is necessary to improve the clinical efficacy of andrological diseases so as to satisfy the needs of patients. Therefore， the China Association of Chinese Medicine （CACM） organized the andrologists of TCM and western medicine and the outstanding young clinicians to discuss the andrological diseases responding specifically to TCM or integrated TCM and western medicine， such as chronic prostatitis， male infertility， benign prostatic hyperplasia， erectile dysfunction， and premature ejaculation， determine their diagnostic criteria in western medicine， and standardize the specifications for TCM diagnosis and treatment based on syndrome differentiation， thus formulating recognized and integrated diagnosis and treatment protocols. Apart from proposing suggestions on the treatment of such andrological diseases with TCM and western medicine， the experts have also figured out the andrological diseases responding specifically to TCM， the optimal intervention time of TCM and western medicine， and the suitable measures including surgery. The resulting consensus helps to better guide the formulation of accurate， personalized， and optimized treatment plans in clinical practice and improve the diagnosis and treatment effects of andrological diseases by giving full play to the advantages of TCM， which will in turn contribute to further innovation and development of TCM.

Mechanism of Wenshen Yangxue Prescription Improving Endometrial Receptivity of Aged Female Mice by Regulating PI3K/Akt/FoxO3A Signaling Pathway / 中国实验方剂学杂志

Objective:To explore the effective components， targets， and possible mechanisms of Wenshen Yangxue prescription in improving endometrial receptivity of aged female mice based on network pharmacology and experimental verification. Method:Based on Bioinformatics Analysis Tool for Molecular mechANism of Traditional Chinese Medicine （BATMAN-TCM） and Integrative Pharmacology-based Research Platform of Traditional Chinese Medicine， the components and targets of Wenshen Yangxue prescription were retrieved， and the targets of ovulatory dysfunctional infertility were collected from the Online Mendelian Inheritance in Man （OMIM） and GeneCards with "anovulatory sterility" and "anovulatory infertility" as keywords. The protein-protein interaction （PPI） network was constructed based on STRING and the core targets of Wenshen Yangxue prescription against ovulatory dysfunctional infertility were screened by Cytoscape， followed by Gene Ontology （GO） term enrichment and Kyoto Encyclopedia of Genes and Genomes （KEGG） pathway enrichment of the core targets in DAVID database. Then， the "medicinal-component-target-pathway" network was established and the core targets were verified by animal experiment. Result:A total of 253 components and 326 targets of Wenshen Yangxue prescription， 819 disease targets， and 74 common targets were screened out. The common targets were mainly involved in the biological processes such as positive regulation of nitric oxide biosynthetic process， positive regulation of cell proliferation， response to estradiol， aging， response to oxidative stress， and angiogenesis. The GO term of response to oxidative stress and five of the top 20 KEGG pathways were analyzed. According to the "medicinal-component-target-biological process/pathway" network， 41 chemical components in 20 medicinals participated in hypoxia inducible factor-1 （HIF-1） signaling pathway， tumor necrosis factor （TNF） signaling pathway， forkhead box O （FOXO） signaling pathway， Toll-like receptor （TLR） signal pathway， and phosphatidylinositol 3-kinase/protein kinase B （PI3K/Akt） signaling pathway by affecting 35 targets. The results of animal experiment showed that the prescription could increase the expression of PI3K， phosphorylated PI3K （p-PI3K）， Akt， phosphorylated Akt （p-Akt）， forkhead box O3A （FoxO3A）， and phosphorylated FoxO3A （p-FoxO3A） in uterus of aged female ICR mice. Conclusion:Wenshen Yangxue prescription interferes with oxidative stress and PI3K/Akt/FoxO3A signaling pathway by influencing Akt1， dual oxidase 2 （DUOX2）， epidermal growth factor receptor （EGFR）， heme oxygenase-1 （HMOX1）， myeloperoxidase （MPO）， and other targets， thereby improving endometrial receptivity of aged female mice.

Obstetric Diseases Responding Specifically to Traditional Chinese Medicine / 中国实验方剂学杂志

In recent years， with the change in life style， social environment， and national childbearing policy， the proportion of high-risk pregnant women has increased significantly， triggering the spectrum of obstetric diseases to constantly change， which has brought new challenges to the diagnosis and treatment of obstetrics. Traditional Chinese medicine （TCM） has been proved effective in dealing with a variety of obstetric diseases， and various treatment methods are available， which can serve as alternative means for solving refractory obstetric diseases. However， most obstetric clinicians are currently less aware of the therapeutic effects of TCM， which has significantly hindered its participation in clinical treatment. Therefore， the China Association of Chinese Medicine （CACM） organized the outstanding young obstetricians of TCM and western medicine to discuss 15 obstetric diseases responding specifically to TCM or integrated TCM and western medicine， including hyperemesis gravidarum， threatened abortion， ectopic gestation， cough during pregnancy， pregnancy-induced hypertension syndrome， maternal-fetal ABO incompatibility， postpartum hypogalactia， residual pregnancy tissue in uterine cavity， puerperal infection， pantalgia after childbirth， hematoma/undesirable healing after caesarean section， postpartum urinary retention， ileus after cesarean section， pelvic floor dysfunction， and postnatal depression. The suggestions for their treatment with TCM or integrated TCM and western medicine were also proposed， aiming to provide patients with effective and personalized treatments in clinical practice and improve the diagnosis and treatment effects of obstetric diseases， thus benefiting the public. At the same time， more obstetrical clinicians are expected to understand the therapeutic effects and advantages of TCM and draw on the strengths of both TCM and western， thereby promoting the establishment of an obstetric diagnosis and treatment system with Chinese characteristics.

Application of Conditioning Regimen with Busulfan and Cyclophosphamide in Autologous Hematopoietic Stem Cell Transplantation in Multiple Myeloma / 中国实验血液学杂志

OBJECTIVE@#To evaluate the safety and efficacy of BUCY (busulfan and cyclophosphamide) conditioning regimen for autologous hematopoietic stem cell transplantation (ASCT) in patients with multiple myeloma (MM).@*METHODS@#The clinical data of 72 MM patients received transplantation in the Hematology Department of the First Affiliated Hospital of Soochow University from May 2012 to June 2015 were retrospectively analyzed. Among them, 36 patients received BUCY conditioning regimen while the others received high-dose melphalan (HDM) conditioning regimen. The complication, post-transplantation hematopoietic reconstitution and efficacy between the two groups were compared.@*RESULTS@#There were no significant differences in sex, age, isotype, stage, induction therapy, mobilization method and proportion of conditioning regimen with Bortezomib between the two groups. The median time of neutrophil engraftment for the patients in BUCY and HDM groups was 10 (8-17) and 10 (9-13) d (P=0.046), and the median time of platelet engraftment was 10 (8-18) and 11 (9-47) d (P=0.017), respectively. The transplant related mortality of the patients in both groups was 2.7%. The CR rates of the patients after ASCT (38.9% and 50.0%) were higher than those before ASCT (27.8% and 19.4%) in the two groups. For the patients in BUCY group, the median follow-up time was 45 (0-61) months. Fifteen patients (41.7%) achieved disease progression. While for the patients in HDM group, the median follow-up time was 52(0-75) months. Twenty-two patients (61.1%) achieved disease progression.@*CONCLUSION@#The BUCY conditioning regimen is a safe and effective therapy for ASCT in patients with MM. Besides, in terms of safety and efficacy, BUCY regimen is not inferior to HDM regimen. BUCY regimen may replace HDM regimen as a standard conditioning regimen for ASCT in MM.

Objective To establish a rapid diagnosis method for the biological toxicity of soil, accurately and rapidly evaluate the toxicity of contaminated sites and identify the dominant pollutants. Methods Take the soil pollution of a galvanized factory as an example, while the metal concentration level was analyzed and detected, a rapid biological toxicity detection method based on the acute toxicity test of luminescent bacteria （Vibrio qinghaiensis sp.-Q67） was established, and the dominant pollutants were identified by stepwise multiple regression. Results The pollutants came from wastewater and metal plating fragments directly discharged from the manufacturing line of the factory. The concentration of those pollutants was correlated with the acute toxicity of Vibrio qinghaiensis sp.-Q67. The dominant pollutants in the study were zinc （Zn）, aluminum （Al） and copper （Cu）. Conclusion The luminescent bacteria toxicity test method based on Vibrio qinghaiensis sp.-Q67 can conveniently and rapidly assess the degree of toxic damage of polluted soil and identify the dominant pollutants and can be applied to the acute toxicity evaluation of polluted soil.

Relationship between mild cognitive impairment and time in the range of blood glucose targets and time below the target range in elderly patients with type 2 diabetes by a cognitive assessment / 中华内分泌代谢杂志

Objective:To investigate the relationship between mild cognitive impairment (MCI) and time in target range (TIR) and time below target glucose range (TBR) in elderly patients with type 2 diabetes.Methods:Ninety-five elderly patients with type 2 diabetes who were admitted to the Henan Provincial People′s Hospital from November 2017 to November 2018 were selected. Patients were assessed for cognitive function using the Montreal cognitive assessment (MoCA), and were classified into mild cognitive impairment group (MCI group) and non-mild cognitive impairment group (non-MCI group) according to the scores; all enrolled patients were scanned with a glucose monitoring system to record TIR and TBR within the first 24 hours of admission.Results:The MoCA score of the patients in the MCI group was (21.3±3.7)point, which was significantly lower than that in the non-MCI group (28.2±1.2)point, P<0.01); the TIR of the patients in the MCI group was significantly lower than that in non-MCI group [(50.6±24.5)% vs (65.8±28.7)%, P<0.01], the TBR of patients in the MCI group was significantly higher than that in the non-MCI group [(6.6±3.2)% vs (1.2±1.9)%, P<0.01]. Correlation analysis showed that MoCA score was negatively correlated with TBR ( r=-0.892, P<0.01) and positively correlated with TIR ( r=0.816, P=0.001). Multivariate linear regression analysis showed that when adjusted for diabetic duration and HbA 1C, TIR and TBR were independent risk factors for MoCA scores. Conclusion:The cognitive level of elderly patients with type 2 diabetes is closely related to TIR and TBR. At the same time, we must pay attention to TBR while increasing TIR.

Traditional Chinese medicine network pharmacology study on exploring the mechanism of Xuebijing Injection in the treatment of coronavirus disease 2019 / 中国天然药物

As a representative drug for the treatment of severe community-acquired pneumonia and sepsis, Xuebijing (XBJ) injection is also one of the recommended drugs for the prevention and treatment of coronavirus disease 2019 (COVID-19), but its treatment mechanism for COVID-19 is still unclear. Therefore, this study aims to explore the potential mechanism of XBJ injection in the treatment of COVID-19 employing network pharmacology and molecular docking methods. The corresponding target genes of 45 main active ingredients in XBJ injection and COVID-19 were obtained by using multiple database retrieval and literature mining. 102 overlapping targets of them were screened as the core targets for analysis. Then built the PPI network, TCM-compound-target-disease, and disease-target-pathway networks with the help of Cytoscape 3.6.1 software. After that, utilized DAVID to perform gene ontology (GO) function enrichment analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis to predict the action mechanism of overlapping targets. Finally, by applying molecular docking technology, all compounds were docked with COVID-19 3 CL protease(3CLpro), spike protein (S protein), and angiotensin-converting enzyme II (ACE2). The results indicated that quercetin, luteolin, apigenin and other compounds in XBJ injection could affect TNF, MAPK1, IL6 and other overlapping targets. Meanwhile, anhydrosafflor yellow B (AHSYB), salvianolic acid B (SAB), and rutin could combine with COVID-19 crucial proteins, and then played the role of anti-inflammatory, antiviral and immune response to treat COVID-19. This study revealed the multiple active components, multiple targets, and multiple pathways of XBJ injection in the treatment of COVID-19, which provided a new perspective for the study of the mechanism of traditional Chinese medicine (TCM) in the treatment of COVID-19.
