This study predicts the quality markers(Q-markers) for the cough-relieving and phlegm-expelling effects of Kening Granules based on pharmacodynamics, plasma drug chemistry, network pharmacology, and pharmacokinetics. Strong ammonia solution spray and phenol red secretion assays were employed to evaluate the cough-relieving and phlegm-expelling effects of Kening Granules. Twentysix absorbed prototype components of Kening Granules were identified by ultra high performance liquid chromatography coupled with QExactive Plus quadrupole/Orbitrap high resolution mass spectrometry(UHPLC-Q-Exactive Plus Orbitrap HRMS). Through network pharmacology, 11 potential active components were screened out for the cough-relieving and phlegm-expelling effects of Kening Granules. The 11 components acted on 40 common targets such as IL6, TLR4, and STAT3, which mainly participated in PI3K/Akt, HIF-1, and EGFR signaling pathways. Pharmacokinetic quantitative analysis was performed for 7 prototype components. Three compounds including azelaic acid, caffeic acid, and vanillin were identified as Q-markers for the cough-relieving and phlegm-expelling effects of Kening Granules based on their effectiveness, transmissibility, and measurability. The results of this study are of great significance for clarifying the pharmacological substance basis, optimizing the quality standards, and promoting the clinical application of Kening Granules.

In this study,nine hybridoma cells secreting monoclonal antibodies against deltamethrin were prepared,and the monoclonal antibody 4D4E11 with best sensitivity was selected to develop indirect enzyme-linked immunosorbent assay (ic-ELISA) and gold nanoparticle-based lateral flow immunoassay (LFIA) for detection of deltamethrin. The optimal working buffer for ic-ELISA was 0.01 mol/L phosphate buffer (pH 7.4) containing 0.2 mol/L NaCl and 20％ methanol,while 0.01 mol/L phosphate buffer (pH 7.4) containing 1 mol/L NaCl,5‰Tween-20 and 10％methanol for LFIA. Under the optimal conditions,the half inhibition concentration (IC50) and limit of detection (IC10) of ic-ELISA were 10.60 ng/mL and 1.43 ng/mL respectively,and the limit of detection of the developed LFIA was 0.5μg/mL. The developed ic-ELISA and LFIA showed no cross-reactivities (CRs) with eight kinds of analogues of deltamethrin,which indicated the excellent specificity of proposed immunoassays. The average recoveries of the ic-ELISA in spiked tomato,cabbage and lettuce samples were 79.8％-92.6％with relative standard deviations of 0.8％-5.5％. The detection results of LFIA were consistent with the spiked concentrations in the range of 1-5 mg/kg. Meanwhile,the results of ic-ELISA and LFIA showed close correlation with high performance liquid chromatography (HPLC) in the test of blind lettuce samples. The experimental results demonstrated that the two immunoassays proposed here were suitable for rapid detection of deltamethrin with high sensitivity and high accuracy.

Objective:To investigate the effect of TCP1 expression on the proliferation and the accumulation of intracellular drug of HL60/A and HL60 cells and its possible molecular mechanism.Methods:Lentiviral transfection technology was used to construct HL60/A and HL60 cells with knocked down or overexpressed TCP1 and their control cells.The efficiency of knockdown and overexpression was evaluated by Western blot.The cell proliferation was detected by CCK-8 assay.The intracellular drug accumulation was detected by laser confocal detection and flow cytometry.The expression levels of MRP1,P-gP and p-AKT were evaluated by flow cytometry and Western blot.Results:After TCP1 was knocked down,the proliferation ability of HL60/A cells was significantly reduced,the accumulation of intracellular drug was significantly increased and the expression of MRP1 and P-gP protein were decreased.After TCP1 was overexpressed,the proliferation ability of HL60 was significantly increased,the accumulation of intracellular drug was significantly decreased and the expression of MRP1 and P-gP protein were increased.Intervention of LY294002 significantly antagonized the promotion on cell proliferation,the inhibition on intracellular drug accumulation and the expression of MRP1 and P-gP mediated by TCP1 overexpressing in HL60 cells.Conclusion:TCP1 can promote cell proliferation,improve the expression of MRP1 and P-gP by activating PI3K/AKT signal,and reduce intracellular drug accumulation.

Objective:To investigate the effect of deacylase Sirtuin 5 in the recovery of hematopoietic stem cells(HSCs)after treated by 5-FU in mouse.Methods:Flow cytometry was used to analyze the effect of SIRT5 deletion on the proportion of hematopoietic stem/progenitor cells(HSPCs)in bone marrow(BM),the proportion of T cells,B cells and myeloid cells(TBM)in peripheral blood(PB)and spleen,and the development of T cells in thymus.Mouse were treated with 5-FU to study the effect of SIRT5 deletion on the cell cycle,apoptosis and the proportion of HSPCs in BM.The effect of SIRT5 deletion on the proliferation of HSCs was analyzed by flow sorting in vitro.Results:SIRT5 deletion did not affect the development of T cells in thymus and the proportion of TBM cells in PB and spleen compared with wild type mice.SIRT5 deletion increased proportion of HSPCs in BM.After 5-FU treatment,the proportion of HSCs in SIRT5 deletion mice was significant decreased(P＜0.05),the HSPC in SIRT5 deletion mice was activated from G0 to G1 phase(P＜0.05),and the proportion of early apoptosis increased(P＜0.05).By monoclonal culture in vitro,the ability of HSCs to form clones in SIRT5 deletion mice was decreased significantly(P＜0.05).Conclusion:SIRT5 deletion lead to a decreased the ability of HSCs to clone in vitro.SIRT5 deletion is not conducive to the recovery of HSPCs injury in mice under hematopoietic stress.

Traumatic dental injuries(TDIs)of teeth occur frequently in children and adolescents.TDIs that impact the periodontal tissues and alveolar tissue can be classified into concussion,subluxation,extrusive luxation,intrusive luxation,lateral luxation,and avulsion.In these TDIs,management of injured soft tissue,mainly periodontal ligament,and dental pulp,is crucial in maintaining the function and longevity of the injured teeth.Factors that need to be considered for management in laxation injuries include the maturation stage of the traumatic teeth,mobility,direction of displacement,distance of displacement,and whether there are alveolar fractures.In avulsion,the maturation stage of the permanent tooth,the out-socket time,storage media/condition of the avulsed tooth,and management of the PDL should also be considered.Especially,in this review,we have subdivided the immature tooth into the adolescent tooth(Nolla stage 9)and the very young tooth(Nolla stage 8 and below).This consensus paper aimed to discuss the impacts of those factors on the trauma management and prognosis of TDI to provide a streamlined guide for clinicians from clinical evaluation,diagnostic process,management plan decision,follow-up,and orthodontic treatment for tooth luxation and avulsion injuries.

Bisphenol A is a common environmental factor and endocrine disruptor that exerts a negative impact on male reproductive ability. By exploring bisphenol A-induced testicular cell death using the Institute of Cancer Research (ICR) mouse model, we found that a ferroptosis phenomenon may exist. Mice were divided into six groups and administered different doses of bisphenol A via intragastric gavage once daily for 45 consecutive days. Serum was then collected to determine the levels of superoxide dismutase and malondialdehyde. Epididymal sperm was also collected for semen analysis, and testicular tissue was collected for ferritin content determination, electron microscope observation of mitochondrial morphology, immunohistochemistry, real-time quantitative polymerase chain reaction, and western blot analysis. Exposure to bisphenol A was found to decrease sperm quality and cause oxidative damage, iron accumulation, and mitochondrial damage in the testes of mice. In addition, bisphenol A was confirmed to affect the expression of the ferroptosis-related genes, glutathione peroxidase 4 (GPX4), ferritin heavy chain 1 (FTH1), cyclooxygenase 2 (COX2), and acyl-CoA synthetase 4 (ACSL4) in mouse testicular tissues. Accordingly, we speculate that bisphenol A induces oxidative stress, which leads to the ferroptosis of testicular cells. Overall, the inhibition of ferroptosis may be a potential strategy to reduce male reproductive toxicity caused by bisphenol A.
