Acute lung injury （ALI） is one of the most common and critical diseases in clinical practice， with extremely high morbidity and mortality， seriously threatening human life and health. The pathogenesis of ALI is complex， in which the inflammatory response is a key factor. Studies have shown that NOD-like receptor protein 3 （NLRP3） inflammasomes are involved in ALI through mechanisms such as inflammation induction， increased microvascular permeability， recruitment of neutrophils， oxidative stress， and pyroptosis， playing a key role in the occurrence and progression of ALI. Therefore， regulating NLRP3 inflammasomes and inhibiting the release of inflammatory factors can alleviate the damage in ALI. At present， ALI is mainly treated by mechanical ventilation and oxygen therapy， which have problems such as high costs and poor prognosis. In recent years， studies have shown that traditional Chinese medicine （TCM） can reduce the inflammatory response and the occurrence of oxidative stress and pyroptosis by regulating the NLRP3 inflammasome， thus alleviating the damage and decreasing the mortality of ALI. Based on the relevant literature in recent years， this article reviews the research progress in TCM treatment of ALI by regulating NLRP3 inflammasomes， discusses how NLRP3 inflammasomes participate in ALI， and summarizes the active ingredients， extracts， and compound prescriptions of TCM that regulate NLRP3 inflammasomes， aiming to provide new ideas for the clinical treatment of ALI and the development of relevant drugs.

Objective To analyze the evaluation value of the standard deviation of erythrocyte volume distribution width(RDW-SD),erythrocyte volume distribution width standard deviation and platelet ratio(RPR)and erythrocyte volume distribution width standard deviation and lymphocyte ratio(RLR)in the de-compensation stage of cirrhosis in primary biliary cholangitis(PBC).Methods The blood routine indexes of 68 patients with PBC admitted and treated in this hospital from January 2019 to June 2021 were retrospective-ly analyzed and divided into the compensation stage(n=36)and decompensation stage(n=32)according to the diagnostic standard.2 mL venous blood was extracted from the patient on an empty stomach in the early morning.The red blood cell(RBC),mean corpuscular volume(MCV),hemoglobin(Hb),hematocrit(HCT),mean erythrocyte hemoglobin content(MCHC),RDW-SD,white blood cell(WBC),neutrophil absolute value(N#),lymphocyte absolute value(L#),platelet count(PLT),mean platelet volume(MPV),platelet volume distribution width(PDW),etc.were detected.The platelet to lymphocyte ratio(PLR),RPR and RLR were calculated.The influencing factors of decompensation stage of PBC cirrhosis were analyzed by binary logistic regression,and the receiver operating characteristic(ROC)curve was used to analyze the diagnostic values of different indicators in the decompensation stage of PBC cirrhosis.Results There were statistically significant differences in age,RBC,Hb,HCT,RDW-SD,L #,PLT,RPR and RLR between the compensation group and decompensation group in PBC cirrhosis(P＜0.05).The binary logistic regression analysis showed that the age[odds ratios(OR)=1.087,95％confidence intervals(CI):1.015-1.165,P＜0.05],RDW-SD(OR=1.144,95％CI:1.030-1.270,P＜0.05)and RLR(OR=1.041,95％CI:1.007-1.075,P＜0.05)were the independent risk factors for progressing to the decompensation stage in the patients with PBC cirrhosis com-pensation stage.The ROC curve analysis showed that the areas under ROC curve(AUC)of RDW-SD,RPR and RLR for the diagnosis alone of decompensation stage of PBC cirrhosis were 0.726,0.778 and 0.798,re-spectively,and the differences were not statistically significant(P＞0.05).Conclusion Combined with the age factor,regular monitoring of RDW-SD,RPR and RLR levels has a high predictive value for the develop-ment of PBC cirrhosis compensation stage to decompensation stage.

After the compatibility of Astragali Radix and Atractylodis Macrocephalae Rhizoma, most of the effective components of Astragali Radix increase, and the bioavailability is improved. Compared with the application of the two drugs alone, it can enhance the effects of immune regulation, anti-tumor, diuresis, lung protection, regulation of flora, and intestinal protection. However, the optimal compatibility ratio of Astragali Radix- Atractylodis Macrocephalae Rhizoma pair to exert various pharmacological effects still needs to be clarified. The drug pair and related preparations are mostly used in the treatment of nephropathy, but its mechanism of action needs to be further elucidated.

Objective:To understand the mediating role of resourcefulness between perceived stress and depression in primary caregivers of stroke patients.Methods:The primary caregivers of 311 inpatients with stroke in three Class Ⅲ Grade A hospitals in Yinchuan from December 2020 to August 2021 were selected by convenience sampling and investigated with the general information form, Resourcefulness Scale (RS) , Chinese Perceived Stress Scale (CPSS) and Self-Rating Depression Scale (SDS) . SPSS 25.0 and PROCESS were used to analyze the relationship between the three, and to explore the mediating role of resourcefulness between perceived stress and depression in the primary caregivers of stroke patients.Results:In this study, 311 questionnaires were distributed, 311 questionnaires were recovered, and 308 questionnaires were valid. The primary caregivers of stroke patients scored (24.98±6.38) for perceived stress, (83.98±12.85) for resourcefulness, and (44.35±8.40) for depression. Resourcefulness was negatively correlated with perceived stress and depression scores ( r=-0.313, -0.317; P <0.01) , and perceived stress was positively correlated with depression ( r=0.425, P<0.01) . The Bootstrap method further validated that resourcefulness played a partial mediating role between perceived stress and depression, and the mediating effect accounted for 14.95% of the total effect. Conclusions:Resourcefulness is a mediating variable between the perceived stress and depression of the primary caregivers of stroke patients, and resourcefulness plays a partial mediating role between perceived stress and depression.

Objective:To analyse the material basis and potential mechanism of Acanthopanax senticosus injection (ASI) in the treatment of ischemic stroke by combining UPLC-Q/TOF-MS and network pharmacology.Methods:The chemical composition of ASI was identified by UPLC-Q/TOF-MS. The Swiss Target Prediction, GeneCards and OMIM databases were used to predict the potential targets for the action of ASI in the treatment of ischemic stroke. The String database and Cytoscape software were used to construct protein interaction network maps, and the Omicshare platform was used to perform gene ontology (GO) and KEGG enrichment analysis.

With the increasing cost of drug development and clinical trials, it is of great value to make full use of all kinds of data to improve the efficiency of drug development and to provide valid information for medication guidelines. Model-based meta-analysis (MBMA) combines mathematical models with meta-analysis to integrate information from multiple sources (preclinical and clinical data, etc.) and multiple dimensions (targets/mechanisms, pharmacokinetics/pharmacodynamics, diseases/indications, populations, regimens, biomarkers/efficacy/safety, etc.), which not only provides decision-making for all key points of drug development, but also provides effective information for rational drug use and cost-effectiveness analysis. The classical meta-analysis requires high homogeneity of the data, while MBMA can combine and analyze the heterogeneous data of different doses, different time courses, and different populations through modeling, so as to quantify the dose-effect relationship, time-effect relationship, and the relevant impact factors, and thus the efficacy or safety features at the level of dose, time and covariable that have not been involved in previous studies. Although the modeling and simulation methods of MBMA are similar to population pharmacokinetics/pharmacodynamics (Pop PK/PD), compared with Pop PK/PD, the advantage of MBMA is that it can make full use of literature data, which not only improves the strength of evidence, but also can answer the questions that have not been proved or can not be answered by a single study. At present, MBMA has become one of the important methods in the strategy of model-informed drug development (MIDD). This paper will focus on the application value, data analysis plan, data acquisition and processing, data analysis and reporting of MBMA, in order to provide reference for the application of MBMA in drug development and clinical practice.
