Screening Effective Sites of Momordicae Semen-Epimedii Folium and Anti-lung Cancer Mechanism of Its Prescription / 中国实验方剂学杂志

ObjectiveTo preliminarily confirm the effective anti-lung cancer sites of Momordicae Semen and Epimedii Folium and study their mechanism of action. MethodOn the basis of preliminary research， the extraction method of Momordicae Semen and Epimedii Folium was optimized and the effective parts were screened under the guidance of pharmacological effects. Different ethanol elution and water elution sites of Momordicae Semen and Epimedii Folium were obtained through adsorption and elution with D101 macroporous resin. The methylthiazolyldiphenyl-tetrazolium bromide （MTT） colorimetric assay was used to detect the effects of total drug extracts and different elution sites on the proliferation of various tumor cell lines， and to screen for the optimal elution site and tumor sensitive strains. Flow cytometry was used to detect the effect of the elution sites of Momordicae Semen and Epimedii Folium on intracellular reactive oxygen species （ROS） and apoptosis in A549 cells. Western blot was used to compare the expressions of tumor protein 53 （p53）， Bcl-2-associated X protein （Bax）， cysteinyl aspartate specific proteinase-3 and 9 （Caspase-3 and Caspase-9） proteins in A549 cells. ResultThe inhibitory effect of Momordicae Semen on the proliferation of A549 cells was better than the kernel of Momordicae Semen， with 50% inhibitory concentration （IC50） being （86.83±2.88） mg·L-1 and （95.10±18.13） mg·L-1， respectively. The effect of total extracts of Epimedii Folium on A549 anti proliferation IC50 value was （4.71±0.81） mg·L-1. The IC50 values of the 40%， 60%， and 80% ethanol and anhydrous ethanol eluted macroporous resins of the total extracts of Momordicae Semen and Epimedii Folium inhibiting A549 proliferation were （45.32±4.38）、 （14.95±0.73）、 （17.07±1.76）、 （14.46±2.35）、 （51.7±2.26）、 （12.37±0.67）、 （20.29±0.93）、 and （3.43±0.91） mg·L-1， respectively. Compared with the normal group， the 1∶1 combination of Momordicae Semen and Epimedii Folium inhibited A549 cell proliferation in a time-dependent and concentration-dependent manner. Compared with the normal group， 50 mg·L-1 of the combination of Momordicae Semen and Epimedii Folium significantly increased intracellular ROS expression （P<0.01）. Compared with the normal group， 12.5， 25， 50 mg·L-1 of the combination of Momordicae Semen and Epimedii Folium significantly increased the expression of A549 cell apoptosis （P<0.01）. Compared with the normal group， 25， 50 mg·L-1 of the combination of Momordicae Semen and Epimedii Folium significantly increased the expression of p53 in A549 cells （P<0.01）. Compared with the normal group， 12.5， 25， 50 mg·L-1 of the combination of Momordicae Semen and Epimedii Folium significantly increased the expression of Bax （P<0.01）. Compared with the normal group， 50 mg·L-1 of the combination of Momordicae Semen and Epimedii Folium significantly reduced the expressions of Caspase-3 and Caspase-9 （P<0.01）. ConclusionThe anti-tumor effect of Momordicae Semen is better than that of the kernel of Momordicae Semen. The anti-tumor substances of Momordicae Semen and Epimedii Folium mainly concentrate in the 60% ethanol to anhydrous ethanol elution site. A549 cells are sensitive to the 1∶1 combination of Momordicae Semen and Epimedii Folium， which can effectively inhibit the cell proliferation. The mechanism may be related to increasing the generation of ROS in A549 cells， promoting their apoptosis， increasing the expressions of apoptotic proteins such as p53 and Bax， and reducing the expressions of Caspase-3 and Caspase-9.

Stellera chamaejasme extract against multidrug resistance of breast cancer cell line MCF-7 / 中国中药杂志

This study explored the effect and underlying mechanism of Stellera chamaejasme extract(SCE) on multidrug resistance of breast cancer. The chemotherapy-sensitive breast cancer cell line MCF-7 and adriamycin(ADR)-resistant cell line MCF-7/ADR were used as experimental subjects. MTT assay was used to detect cell proliferation activity. Pi staining was used to detect the cell cycle. 4',6-Diamidino-2-phenylindole, dihydrochloride(DAPI) staining and flow cytometry were used to detect apoptosis. Dansylcadaverine(MDC) staining and GFP-LC3B-Mcherry adenovirus transfection were used to detect autophagy. The protein expression of Bcl-2, Bax, caspase-9, caspase-3, LC3B, p62, and Beclin-1 was detected by Western blot. The results showed that SCE could significantly inhibit the proliferation of both sensitive and resistant breast cancer cell lines. The drug resistance factor was 0.53, which was significantly lower than 59 of ADR. Meanwhile, the proportion of sensitive/resistant cells in the G_0/G_1 phase increased significantly after SCE treatment. In addition, DAPI staining showed that a series of apoptosis phenomena such as nuclear pyknosis, staining deepening, and nuclear fragmentation appeared in sensitive/resistant cell lines after SCE administration. Moreover, the results of flow cytometry double staining showed that the proportion of apoptotic cells in sensitive/resistant cell lines increased significantly after SCE administration. Besides, Western blot showed that the protein expression levels of caspase-3, caspase-9, and Bcl-2 significantly decreased and the expression level of Bax protein significantly increased in both breast cancer cell lines after SCE administration. Furthermore, SCE could also increase the positive fluorescent spots after MDC staining and yellow fluorescent spots after GFP-LC3B-mcherry transfection, and up-regulate the expression levels of autophagy-related proteins LC3B-Ⅱ, p62, and Beclin-1 in breast cancer cells. In summary, SCE may play the role of anti-multidrug resistance by blocking the cell cycle of breast cancer multidrug-resistant cells, blocking autophagy flow, and ultimately interfering with the apoptosis resistance of drug-resistant cells.

Neutralization against SARS-CoV-2 Delta/Omicron variants and B cell response after inactivated vaccination among COVID-19 convalescents / 医学前沿

Emerging SARS-CoV-2 variants have made COVID-19 convalescents susceptible to re-infection and have raised concern about the efficacy of inactivated vaccination in neutralization against emerging variants and antigen-specific B cell response. To this end, a study on a long-term cohort of 208 participants who have recovered from COVID-19 was conducted, and the participants were followed up at 3.3 (Visit 1), 9.2 (Visit 2), and 18.5 (Visit 3) months after SARS-CoV-2 infection. They were classified into three groups (no-vaccination (n = 54), one-dose (n = 62), and two-dose (n = 92) groups) on the basis of the administration of inactivated vaccination. The neutralizing antibody (NAb) titers against the wild-type virus continued to decrease in the no-vaccination group, but they rose significantly in the one-dose and two-dose groups, with the highest NAb titers being observed in the two-dose group at Visit 3. The NAb titers against the Delta variant for the no-vaccination, one-dose, and two-dose groups decreased by 3.3, 1.9, and 2.3 folds relative to the wild-type virus, respectively, and those against the Omicron variant decreased by 7.0, 4.0, and 3.8 folds, respectively. Similarly, the responses of SARS-CoV-2 RBD-specific B cells and memory B cells were boosted by the second vaccine dose. Results showed that the convalescents benefited from the administration of the inactivated vaccine (one or two doses), which enhanced neutralization against highly mutated SARS-CoV-2 variants and memory B cell responses. Two doses of inactivated vaccine among COVID-19 convalescents are therefore recommended for the prevention of the COVID-19 pandemic, and vaccination guidelines and policies need to be updated.

Renin-angiotensin system inhibitor is associated with the reduced risk of all-cause mortality in COVID-19 among patients with/without hypertension / 医学前沿

Consecutively hospitalized patients with confirmed coronavirus disease 2019 (COVID-19) in Wuhan, China were retrospectively enrolled from January 2020 to March 2020 to investigate the association between the use of renin-angiotensin system inhibitor (RAS-I) and the outcome of this disease. Associations between the use of RAS-I (angiotensin-converting enzyme inhibitor (ACEI) or angiotensin receptor blocker (ARB)), ACEI, and ARB and in-hospital mortality were analyzed using multivariate Cox proportional hazards regression models in overall and subgroup of hypertension status. A total of 2771 patients with COVID-19 were included, with moderate and severe cases accounting for 45.0% and 36.5%, respectively. A total of 195 (7.0%) patients died. RAS-I (hazard ratio (HR)= 0.499, 95% confidence interval (CI) 0.325-0.767) and ARB (HR = 0.410, 95% CI 0.240-0.700) use was associated with a reduced risk of all-cause mortality among patients with COVID-19. For patients with hypertension, RAS-I and ARB applications were also associated with a reduced risk of mortality with HR of 0.352 (95% CI 0.162-0.764) and 0.279 (95% CI 0.115-0.677), respectively. RAS-I exhibited protective effects on the survival outcome of COVID-19. ARB use was associated with a reduced risk of all-cause mortality among patients with COVID-19.

Risk factors for herb-induced liver injury / 临床肝胆病杂志

Drug-induced liver injury (DILI) is one of the common adverse drug reactions and is the main cause of withdrawal of drugs after marketing, which has attracted more and more attention of the public, and herb-induced liver injury (HILI) is a special type of DILI. In recent years, the frequent occurrence of HILI not only seriously endangers the health of patients, but also causes the controversy over the safety of traditional Chinese medicine. Therefore, this article reviews the potential risk factors for HILI from the three aspects of "patient", "drug", and "use", so as to provide a basis for the objective identification, prevention, and control of HILI and a reference for the construction of traditional Chinese medicine pharmacovigilance system represented by liver injury.

Regulation of liver fibrosis by matrix metalloproteinase/tissue inhibitor of metalloproteinase and research advances in related therapeutic drugs / 临床肝胆病杂志

Liver fibrosis is the common consequence of various chronic liver injuries and is mainly characterized by the imbalance between the production and degradation of extracellular matrix, which leads to the accumulation of interstitial collagen and other matrix components. Matrix metalloproteinases (MMPs) and their specific inhibitors, i.e., tissue inhibitors of metalloproteinases (TIMPs), play a crucial role in collagen synthesis and lysis. Through a literature review, this article reviews the experimental studies of liver fibrosis based on MMPs/TIMPs, summarizes the components that may exert an anti-liver fibrosis effect by affecting the expression or activity of MMPs/TIMPs, and attempts to clarify the mechanism of MMPs/TIMPs in regulating collagen homeostasis, so as to provide support for the development of anti-liver fibrosis drugs.

Mechanism of action of nucleotide-binding oligomerization domain-like receptor protein 3 inflammasome in liver diseases / 临床肝胆病杂志

Inflammasomes play an important role in the innate immunity of the liver; however, the excessive activation of inflammasomes can lead to liver inflammation and injury. The mechanism of nucleotide-binding oligomerization domain-like receptor protein 3 (NLRP3) inflammasome-mediated liver injury has been extensively studied. Related studies have shown that the development of various liver diseases may be associated with the excessive activation of inflammasomes, especially NLRP3 inflammasome. This article reviews inflammasomes, the activation mechanism of NLRP3 inflammasome, and the role of NLRP3 inflammasome in different liver diseases, so as to provide a reference for the treatment targets of liver diseases from the perspective of NLRP3 inflammasome.

Multidrug Resistance in Breast Cancer and Coping Strategies of Chinese Medicine： A Review / 中国实验方剂学杂志

Breast cancer， as a kind of malignant tumor with high incidence rate in female population， poses a great threat to people's health. At present， chemotherapy is the main treatment for breast cancer besides surgery and radiotherapy. However， chemotherapy is often accompanied by multidrug resistance （MDR）， which results in a series of severe consequences such as low efficacy， relapse of cancer after drug withdrawal， increased consumption of medical resources， and increased burden of medical system. Previous studies showed that the mechanism of MDR in breast cancer was quite complex， involving drug efflux， deoxyribonucleic acid （DNA） damage repair， tumor microenvironment， autophagy， epigenetic regulation， tumor stem cells， lipid metabolism， and so on. In addition， there were extensive connections among the mechanisms of MDR. Therefore， it is necessary to reveal the mechanism of MDR and develop corresponding drugs to reverse MDR， thus improving the effect of chemotherapy on treating breast cancer. Chinese medicine has the advantages of high efficiency， low toxicity， multi targets， and overall regulation. Various studies found that Chinese medicine monomer， single drug， and compound were able to reverse MDR in breast cancer by regulating the expression of drug efflux protein， promoting apoptosis， and regulating autophagy， showing the potential of anti-MDR in breast cancer. This paper summarized the research progress of the mechanism of MDR in breast cancer and the strategies of Chinese medicine in coping with MDR in breas cancer in recent years， and provided references for further research.

The predictive value of time series forecasting model in prehospital emergency medical services demand in Guangzhou / 中华急诊医学杂志

Objective:To study the value of autoregressive integrated moving average (ARIMA) and autoregressive (AR) models in predicting the daily number of ambulances in prehospital emergency medical services demand in Guangzhou.Methods:Matlab simulation software was used to analyze the emergency dispatching departure records in Guangzhou from January 1, 2021 to December 31, 2021. A time series for the number of ambulances per day was calculated. After identifying the time series prediction model, ARIMA(1,1,1), AR(4) and AR(7) models were obtained. These models were used to predict the number of ambulances per day. ARIMA(1,1,1) model divided the time series into the training set and test set. Prony method was used for parameter calculation, and the demands of number of ambulances of the next few months were forecasted. AR(4) and AR(7) models used uniformity coefficient to forecast the demands of number of ambulances on that very day.Results:ARIMA(1,1,1), AR(4) and AR(7) can effectively predict the number of ambulances per day. The prediction fitting error of ARIMA (1,1,1) decreased with the extension of prediction time. The mean absolute percentage error (MAPE) of forecast results of daily vehicle output of emergency dispatching within two months was less than 6% and the predicted results were almost within the 95% confidence interval. The residual analysis of the model verified that the model was significantly effective.Conclusions:ARIMA model can make a long-term within two months and effective prediction fitting of the daily vehicle output of emergency dispatching, and AR model can make a short-term and effective prediction of the daily vehicle output of emergency dispatching.

Silencing AEBP2 Inhibits the Proliferation and Migration of Hepatocellular Carcinoma Cells via the PI3K/Akt Signaling Pathway / 中国生物化学与分子生物学报

Adipocyte enhancer binding protein 2, as a component protein of Polycomb repressive complex (PRC2), is involved in the proliferation and migration of many tumor cells. However, its role in HCC is still unclear. In this study, we identify that AEBP2 was upregulated in HCC samples from the UALCAN and Kaplan-Meier Plotter database, which was correlated to the overall survival time of HCC patients. Real-time quantitative PCR and Western blotting confirmed that the expression of AEBP2 in HCC cells was higher than normal liver cells. After silencing AEBP2 in HepG2 and Huh-7 cells, the effects of the proliferation, apoptosis, migration and invasion were detected by colony formation, CCK-8, flow cytometry, scratch healing and Transwell chamber, respectively. Compared with the control group, down-regulation of AEBP2 expression inhibited the proliferation, migration and invasion in HepG2 and Huh-7 cells, as well as promoted apoptosis (P<0. 05). Immunofluorescence and Western blotting results showed that AEBP2 silencing inhibited epithelial-mesenchymal transformation (EMT) (P < 0. 05). Bioinformatics analysis showed that AEBP2 is involved the PI3K/Akt signaling pathway. Western blotting results confirmed that silencing AEBP2 down-regulated the expression levels of PI3K, p-AKT (S473), mTOR, MMP-2 and MMP-9 proteins (P<0. 05). In addition, the effects of AEBP2 silencing on HepG2 cells migration and invasion could be reversed by PI3K/Akt pathway agonist insulin-like Growth Factors (IGF-1) (P < 0. 01). In summary, our study showed that AEBP2 promoted the proliferation and migration of HCC cell by regulating PI3K/AKT pathway. This study provided a theoretical basis for the role of AEBP2 in HCC.

Effects of terpinene-4-ol on malignant behavior of colorectal cancer cells and its mechanism / 中国药理学通报

Aim To investigate the effect of terpinene 4-alcohol(T4O)on the malignant behavior of colorectal cancer cell RKO and HCT116 and the underlying mechanism. Methods RKO and HCT116 cells were treated with 0, 1, 2, 4 μmol·L-1 T4O and 4 μmol·L-1 5-Fu, respectively. The proliferation, clonal formation, apoptosis, cell cycle, migration and invasion of RKO and HCT116 cells were detected by CCK-8, colony formation, flow cytometry, wound healing and Transwell assay; the expressions of E-Cadherin, N-Cadherin, p21, CyclinB1 and cleaved-Caspase7 in each group of cells were detected by Western blot. Based on pharmacophore, the target of T4O was analyzed and then the effects of T4O on the expression and degradation rate of NR3C1 were explored. NR3C1 knockdown cells were constructed, and the effects of NR3C1 knockdown on the proliferating and migrating inhibition induced by T4O were detected by wound healing and CCK-8 assay. Results T4O significantly inhibited the proliferation, colony formation, migration and invasion of RKO and HCT116 cells, as well as induced apoptosis and G1 phase arrest(P all <0. 05). The effect of T4O was better than that induced by 5-Fu with the same dose. T4O obviously reduced N-Cadherin and Cyclin B1 expression, and elevated the E-Cadherin, p21 and cleaved-Caspase7 expression(P all <0. 05). A total of 10 targets of T4O were discovered, among which NR3C1 had the highest binding score. After T4O treatment, NR3C1 level in cells increased obviously, and the degradation rate decreased markedly(P<0.05). NRC3C1 knockdown significantly relieved the inhibitory effects of T4O on cell prolfieration and migration(P<0.05). Conclusion T4O can inhibit the malignant behavior of colorectal cancer cells RKO and HCT116 by maintaining the stability of NR3C1 protein.
