Objective To investigate the clinical characteristics of stasis-toxin pathogenesis in patients with non-small cell lung cancer(NSCLC)of blood stasis and qi stagnation type,and to explore the interventional mechanism of adjuvant therapy with Bufei Huayu Decoction.Methods Seventy-eight patients with NSCLC of blood stasis and qi stagnation type admitted to the Department of Respiratory Medicine of Liu'an Hospital of Traditional Chinese Medicine from January 2021 to September 2022 were selected as the NSCLC group,and 71 volunteers who underwent physical examination during the same period served as the healthy control group.The clinical characteristics of stasis-toxin pathogenesis in the NSCLC group were observed,and the differences in the indicators of coagulation function were compared between NSCLC group and the healthy control group.According to the therapy,the NSCLC patients were divided into Bufei Huayu Decoction group(40 cases)and conventional treatment group(38 cases).The conventional treatment group was treated with conventional chemotherapy,while Bufei Huayu Decoction group was treated with Bufei Huayu Decoction together with conventional chemotherapy.Three weeks constituted one course of treatment,and the treatment lasted for 2 courses.The changes of traditional Chinese medicine(TCM)syndrome scores,Karnofsky Performance Status(KPS)score,coagulation function,immune function,serum nitric oxide(NO),vascular endothelial growth factor(VEGF)level in Bufei Huayu Decoction group and conventional treatment group were observed before and after treatment.Moreover,the clinical efficacy of the two groups and the occurrence of adverse reactions were compared during the treatment period.Results(1)NSCLC patients were classified into the clinical stages Ⅲ and Ⅳ and the pathological types of squamous carcinoma and adenocarcinoma,had the high proportion of KPS scores lower than 70,and were scored with high TCM syndrome scores,suggesting that the illness condition of patients with NSCLC was serious.Compared with the healthy control group,plasminogen time(PT)and thrombin time(TT)in NSCLC patients were significantly shortened,and levels of fibrinogen(FIB)and D-dimer(D-D)were significantly increased,and the differences were statistically significant(P<0.01).(2)After 6 weeks of treatment,the total effective rate and total stability rate of Bufei Huayu Decoction group were 32.50%(13/40)and 85.00%(34/40),which were significantly superior to those of the conventional treatment group[versus 13.16%(5/38)and 60.53%(23/38)],and the differences were statistically significant(P<0.05).(3)After 3 weeks of treatment,obvious improvement was presented in the scores of all the TCM symptoms of fatigue,chest distress and shortness of breath,stabbing pain in the chest,and blood stasis in the vessels and collaterals of Bufei Huayu Decoction group and in the scores of the fatigue,chest distress and shortness of breath of the conventional treatment group when compared with those before treatment(P<0.05).After 6 weeks of treatment,all of the TCM syndrome scores of the two groups were improved compared with those before treatment and after three weeks of treatment(P<0.05).The intergroup comparison showed that except for the scores of chest distress and shortness of breath after 3 weeks of treatment,the effect on improving all of the TCM syndrome scores in Bufei Huayu Decoction group was significantly superior to that in the conventional treatment group after 3 and 6 weeks of treatment(P<0.05 or P<0.01).(4)After 6 weeks of treatment,the levels of coagulation function indicators of PT,TT,FIB and D-D in the Bufei Huayu Decoction group were significantly improved compared with those before treatment(P<0.05),while only FIB and D-D in the conventional treatment group were improved compared with those before treatment(P<0.05).The intergroup comparison showed that Bufei Huayu Decoction group had stronger effect on improving the levels of PT,FIB and D-D than the conventional treatment group(P<0.05).(5)After 6 weeks of treatment,the serum NO and VEGF levels in both groups were significantly lower than those before treatment(P<0.05),and the effect on lowering serum NO and VEGF levels of the Bufei Huayu Decoction group was significantly superior to that of the conventional treatment group(P<0.01).(6)After 6 weeks of treatment,the immune function parameters of CD3+,CD4+ levels and CD4+/CD8+ ratio in the Bufei Huayu Decoction group were increased(P<0.05)and CD8+level was decreased(P<0.05)as compared with those before treatment,whereas CD3+,CD4+ levels and CD4+/CD8+ ratio in the conventional treatment group were decreased(P<0.05)and CD8+ level was increased(P<0.05).The intergroup comparison showed that the effect of Bufei Huayu Decoction group on the increase of CD3+,CD4+ levels and CD4+/CD8+ ratio and the effect on the decrease of CD8+ level were significantly superior to those of the conventional treatment group(P<0.01).(7)In terms of the quality of life,the KPS scores of patients in the two groups after 6 weeks of treatment were significantly higher than those before treatment(P<0.05),and the effect of Bufei Huayu Decoction group on the increase of KPS scores was significantly superior to that of the conventional treatment group(P<0.01).(8)During the course of treatment,the incidence of adverse reactions such as gastrointestinal reactions and alopecia in the two groups was not statistically significant(P>0.05),while the incidence of hepatic and renal impairment,bone marrow suppression,and toxicity of oral mucosa in Bufei Huayu Decoction group was significantly lower than that of the conventional treatment group(P<0.05 or P<0.01),suggesting that Bufei Huayu Decoction group reduced the adverse reactions induced by chemotherapy to a certain extent.Conclusion Patients with NSCLC of blood stasis and qi stagnation type generally have advanced disease progression and high blood coagulation,which is consistent with the stasis-toxin pathogenesis in TCM.The use of Bufei Huayu Decoction against the stasis-toxin pathogenesis can significantly improve patients'TCM syndrome scores and coagulation function,down-regulate the levels of serum NO and VEGF,and improve the immune function,which brings about the enhancement of clinical efficacy and quality of life,and the reduction of adverse reactions caused by chemotherapy,with a high safety.

Objective Recombinase-aided polymerase chain reaction(RAP)is a sensitive,single-tube,two-stage nucleic acid amplification method.This study aimed to develop an assay that can be used for the early diagnosis of three types of bacteremia caused by Staphylococcus aureus(SA),Pseudomonas aeruginosa(PA),and Acinetobacter baumannii(AB)in the bloodstream based on recombinant human mannan-binding lectin protein(M1 protein)-conjugated magnetic bead(M1 bead)enrichment of pathogens combined with RAP. Methods Recombinant plasmids were used to evaluate the assay sensitivity.Common blood influenza bacteria were used for the specific detection.Simulated and clinical plasma samples were enriched with M1 beads and then subjected to multiple recombinase-aided PCR(M-RAP)and quantitative PCR(qPCR)assays.Kappa analysis was used to evaluate the consistency between the two assays. Results The M-RAP method had sensitivity rates of 1,10,and 1 copies/μL for the detection of SA,PA,and AB plasmids,respectively,without cross-reaction to other bacterial species.The M-RAP assay obtained results for<10 CFU/mL pathogens in the blood within 4 h,with higher sensitivity than qPCR.M-RAP and qPCR for SA,PA,and AB yielded Kappa values of 0.839,0.815,and 0.856,respectively(P<0.05). Conclusion An M-RAP assay for SA,PA,and AB in blood samples utilizing M1 bead enrichment has been developed and can be potentially used for the early detection of bacteremia.

Objective To explore the biomarkers and potential mechanisms of chronic restraint stress-induced myocardial injury in hyperlipidemia ApoE-/-mice.Methods The hyperlipidemia combined with the chronic stress model was established by restraining the ApoE-/-mice.Proteomics and bioinformatics techniques were used to describe the characteristic molecular changes and related regulatory mechanisms of chronic stress-induced myocardial injury in hyperlipidemia mice and to explore potential diagnostic biomarkers.Results Proteomic analysis showed that there were 43 significantly up-regulated and 58 sig-nificantly down-regulated differentially expressed proteins in hyperlipidemia combined with the restraint stress group compared with the hyperlipidemia group.Among them,GBP2,TAOK3,TFR1 and UCP1 were biomarkers with great diagnostic potential.KEGG pathway enrichment analysis indicated that fer-roptosis was a significant pathway that accelerated the myocardial injury in hyperlipidemia combined with restraint stress-induced model.The mmu_circ_0001567/miR-7a/Tfr-1 and mmu_circ_0001042/miR-7a/Tfr-1 might be important circRNA-miRNA-mRNA regulatory networks related to ferroptosis in this model.Conclusion Chronic restraint stress may aggravate myocardial injury in hyperlipidemia mice via ferrop-tosis.Four potential biomarkers are selected for myocardial injury diagnosis,providing a new direction for sudden cardiac death(SCD)caused by hyperlipidemia combined with the restraint stress.
