ObjectiveTo screen suitable packaging and storage conditions for small packaged Alismatis Rhizoma decoction pieces, laying the foundation for developing standardized storage, maintenance techniques and determining shelf life. MethodsUsing the accelerated stability test method, the small packaged decoction pieces of Alismatis Rhizoma were placed in polyethylene plastic bags, aluminum foil polyethylene composite bags, and cowhide coated paper bags under temperature of (40±2) ℃ and relative humidity of (75±5)% conditions, the quality testing was conducted at the end of the 0th, 1st, 2nd, 3rd, and 6th month, respectively. Using long-term stability test method, an orthogonal experiment was designed to investigate storage conditions, packaging materials, and packaging methods. At the end of the 0th, 1st, 3rd, 6th, 9th, 12th, 18th, and 24th month, the quality of small packaged Alismatis Rhizoma decoction pieces was tested under different packaging and storage conditions(including 2 packaging methods:vacuum packaging and sealed packaging, 3 storage conditions:room temperature, cool, and modified atmosphere, 3 packaging materials:cowhide coated paper bag, aluminum foil polyethylene composite bag, and polyethylene plastic bag). Then, the G1-entropy weight method combined with orthogonal experiment was used to analyze the quality changes of the decoction pieces under different packaging and storage conditions to identify optimal packaging and storage conditions. The quality testing indicators for Alismatis Rhizoma decoction pieces were expanded beyond those specified in the 2020 edition of the Pharmacopoeia of the People's Republic of China. In addition to the existing indicators(characteristics, moisture content, extractives, and the total content of 23-acetyl alisol B and 23-acetyl alisol C), new indicators including color value, water activity, total triterpenoid content, and alisol B content have been added. ResultsThe accelerated stability test results indicated that the quality of small packaged Alismatis Rhizoma decoction pieces was more stable when packaged in aluminum foil-polyethylene composite materials compared to cowhide-coated paper bags and polyethylene plastic bags. Analysis of the long-term stability test results using the G1-entropy weight method combined with orthogonal experiment revealed that storage conditions had the greatest impact on both raw and salt-processed products, followed by packaging materials, while the packaging method had the least influence. For both types of small packaged Alismatis Rhizoma decoction pieces, modified atmosphere storage demonstrated superior efficacy compared to cool storage or room temperature storage. Storage in aluminum foil-polyethylene composite bags was superior to polyethylene plastic bags or cowhide-coated paper bags. However, the stability of sealed raw products was better than vacuum-packed ones, whereas vacuum-packed salt-processed products exhibited greater stability than their sealed counterparts. ConclusionBased on the results of the quality changes of small packaged Alismatis Rhizoma decoction pieces under different storage conditions, it is recommended that the suitable storage packaging conditions for small packaged raw products are sealed packaging with aluminum foil polyethylene composite bags and controlled atmosphere storage, and the suitable storage and packaging conditions for small packaged salt-processed products are vacuum packaging with aluminum foil polyethylene composite bags and controlled atmosphere storage.

ObjectiveTo observe the effects of Yiqi Huoxue Jiedu formula(YHJF) on immune cell exhaustion in the spleen of septic mice and to explore and validate its potential intervention targets. MethodsMice were randomly divided into the sham-operated, model, low-dose YHJF(4.1 g·kg-1), and high-dose YHJF(8.2 g·kg-1) groups. Except for the sham-operated group, a cecal ligation and puncture(CLP) procedure was performed to establish a mouse sepsis model. The treatment groups received oral administration of the corresponding doses, while the sham-operated and model groups received an equal volume of physiological saline. After the intervention, the 7-day survival rate of each group was recorded, and spleen samples were collected 72 h post-intervention, and the spleen index was calculated. Terminal deoxynucleotidyl transferase deoxyuridine triphosphate(dUTP) nick end labeling(TUNEL) staining was used to detect apoptosis in spleen cells. Enzyme-linked immunosorbent assay(ELISA) was performed to measure the levels of interleukin(IL)-4 and IL-10 in the serum. Transcriptomics and metabolomics were used to screen for differentially expressed genes(DEGs) and differential metabolites in the spleen, followed by bioinformatics analysis to identify key targets. Real-time quantitative polymerase chain reaction(Real-time PCR), flow cytometry, and multiplex immunofluorescence were used to verify the expressions of key genes and proteins. ResultsThe high-dose YHJF group significantly improved the 7-day survival rate of septic mice(P0.05). Compared with the sham-operated group, the model group showed a significant increase in apoptosis of spleen cells and a decrease in the spleen index at 72 h post-modeling, with markedly elevated peripheral serum IL-4 and IL-10 levels(P0.01). Compared with the model group, the high-dose YHJF group showed a reduction in apoptosis of spleen cells, an increase in the spleen index, and a significant decrease in peripheral serum IL-4 and IL-10 levels(P0.05). Spleen transcriptomics identified 255 DEGs between groups, potentially serving as intervention targets for YHJF. Gene Ontology(GO) enrichment analysis revealed that DEGs were mainly involved in biological processes such as natural killer(NK) cell-mediated positive immune regulation, cell killing, cytokine production, positive regulation of innate immune cells, and interferon production. Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway enrichment analysis showed that DEGs were mainly involved in cytokine-cytokine receptor interactions, viral protein interactions with cytokines and cytokine receptors, chemokine signaling pathway, and nuclear transcription factor-κB(NF-κB) signaling pathway. Protein-protein interaction(PPI) network analysis identified CD160, granzyme B(GZMB), and chemokine ligand 4(CCL4) as key targets for YHJF in treating sepsis. Metabolomics identified 46 differential metabolites that were significantly reversed by YHJF intervention, and combined transcriptomics and metabolomics analysis identified 17 differential metabolites closely related to CD160. Pathway enrichment revealed that these metabolites were mainly involved in glycerophospholipid metabolism, arachidonic acid metabolism, glycosylphosphatidylinositol(GPI) anchor biosynthesis, linoleic acid metabolism, and α-linolenic acid metabolism pathways. Verification results showed that, compared with the sham-operated group, the model group exhibited significantly elevated CD160 mRNA expression level in the spleen, along with markedly decreased CCL4 and GZMB mRNA expression, and had a significant increase in CD160 expression on the surface of natural killer T(NKT) cells in the spleen(P0.01). Compared with the model group, the high-dose YHJF group had a significant decrease in CD160 mRNA expression in the spleen, a significant increase in CCL4 and GZMB mRNA expressions. Further flow cytometry and immunofluorescence revealed that compared with the sham-operated group, CD160 expression on the surface of splenic NKT cells in the model group was significantly increased(P0.01), while high-dose YHJF intervention significantly reduced CD160 expression(P0.01). ConclusionYHJF may alleviate NKT cell exhaustion in sepsis by downregulating the expression of the negative co-stimulatory molecule CD160, and this regulatory effect is closely related to fatty acid metabolism pathways. This study provides new insights and targets for further exploration of strengthening vital Qi and detoxifying strategy to improve immune cell exhaustion in acute deficiency syndrome of sepsis.

OBJECTIVE To investigate the targeting effect of folic acid-modified crebanine nanoparticles (FA-Cre@PEG- PLGA NPs, hereinafter referred to as “NPs”) combined with ultrasound irradiation on M109 cells in vitro and in vivo after administration, and explore the anti-tumor mechanism. METHODS CCK-8 assay was used to detect the inhibitory effect of NPs combined with ultrasound irradiation on the proliferation of M109 cells, and the best ultrasound time was selected. Using human lung cancer A549 cells as a control, the targeting of NPs combined with ultrasound irradiation to M109 cells was evaluated by free folic acid blocking assay and cell uptake assay. The effects of NPs combined with ultrasound irradiation on the migration, invasion, apoptosis, cell cycle and reactive oxygen species (ROS) levels of M109 cells were detected by cell scratch test, Transwell chamber test and flow cytometry at 1 h after 958401536@qq.com administration; the changes of mitochondrial membrane potential (MMP) were observed by fluorescence inverted microscope. A mouse subcutaneous tumor model of M109 cells was constructed, and the in vivo tumor targeting of NPs combined with ultrasound irradiation was investigated by small animal in vivo imaging technology. RESULTS NPs combined with ultrasound irradiation could significantly inhibit the proliferation of M109 cells, and the optimal ultrasound time was 1 h after administration. The free folic acid could antagonize the inhibitory effect of NPs on the proliferation of M109 cells, and combined with ultrasound irradiation could partially reverse this antagonism. Compared with A549 cells, the uptake rate of NPs in M109 cells was significantly higher (P<0.01), and ultrasound irradiation could promote cellular uptake. NPs combined with ultrasound irradiation could inhibit the migration and invasion of M109 cells and block the cell cycle in the G0/G1 and G2/M phases. Compared with control group, the apoptosis rate of M109 cells and ROS level were increased significantly (P<0.01), while the MMP decreased significantly (P<0.01) in the different concentration (100, 200, 300 μg/mL) groups of M109 cells. Compared with the mice in non-ultrasound group, the fluorescence intensity and tumor-targeting index of the tumor site in the 0 h ultrasound group were significantly enhanced (P<0.05 or P<0.01). CONCLUSIONS NPs combined with ultrasound irradiation have a strong targeting effect on M109 cells in vitro and in vivo, the anti-tumor mechanism includes inhibiting cell migration and invasion, blocking cell cycle, and inducing apoptosis.

Based on the interleukin-17(IL-17) signaling pathway, this study explores the effect and mechanism of Bufei Decoction on Klebsiella pneumoniae pneumonia in rats. SD rats were randomly divided into the control group, model group, Bufei Decoction low-dose group(6.68 g·kg~(-1)·d~(-1)), Bufei Decoction high-dose group(13.36 g·kg~(-1)·d~(-1)), and dexamethasone group(1.04 mg·kg~(-1)·d~(-1)), with 10 rats in each group. A pneumonia model was established by tracheal drip injection of K. pneumoniae. After successful model establishment, the improvement in lung tissue damage was observed following drug administration. Core targets and signaling pathways were screened using transcriptomics techniques. Real-time fluorescence quantitative polymerase chain reaction was used to detect the mRNA expression of core targets interleukin-6(IL-6), interleukin-1β(IL-1β), tumor necrosis factor-α(TNF-α), and chemokine CXC ligand 6(CXCL6). Western blot was used to assess key proteins in the IL-17 signaling pathway, including interleukin-17A(IL-17A), nuclear transcription factor-κB activator 1(Act1), tumor necrosis factor receptor-associated factor 6(TRAF6), and downstream phosphorylated p38 mitogen-activated protein kinase(p-p38 MAPK), and phosphorylated nuclear factor-κB p65(p-NF-κB p65). Apoptosis of lung tissue cells was detected by terminal deoxynucleotidyl transferase-mediated dUTP-biotin nick end labeling(TUNEL). The results showed that, compared with the control group, the model group exhibited significant pathological damage in lung tissue. The mRNA expression of IL-6, IL-1β, TNF-α, and CXCL6, as well as the protein levels of IL-17A, Act1, TRAF6, p-p38 MAPK/p38 MAPK, and p-NF-κB p65/NF-κB p65, were significantly increased, and the number of apoptotic cells was notably higher, indicating successful model establishment. Compared with the model group, both low-and high-dose groups of Bufei Decoction showed reduced pathological damage in lung tissue. The mRNA expression levels of IL-6, IL-1β, TNF-α, and CXCL6, and the protein levels of IL-17A, Act1, TRAF6, p-p38 MAPK/p38 MAPK, and p-NF-κB p65/NF-κB p65, were significantly decreased, with a significant reduction in apoptotic cells in the high-dose group. In conclusion, Bufei Decoction can effectively improve lung tissue damage and reduce inflammation in rats with K. pneumoniae. The mechanism may involve the regulation of the IL-17 signaling pathway and the reduction of apoptosis.

Cemental tear is a rare and indetectable condition unless obvious clinical signs present with the involvement of surrounding periodontal and periapical tissues. Due to its clinical manifestations similar to common dental issues, such as vertical root fracture, primary endodontic diseases, and periodontal diseases, as well as the low awareness of cemental tear for clinicians, misdiagnosis often occurs. The critical principle for cemental tear treatment is to remove torn fragments, and overlooking fragments leads to futile therapy, which could deteriorate the conditions of the affected teeth. Therefore, accurate diagnosis and subsequent appropriate interventions are vital for managing cemental tear. Novel diagnostic tools, including cone-beam computed tomography (CBCT), microscopes, and enamel matrix derivatives, have improved early detection and management, enhancing tooth retention. The implementation of standardized diagnostic criteria and treatment protocols, combined with improved clinical awareness among dental professionals, serves to mitigate risks of diagnostic errors and suboptimal therapeutic interventions. This expert consensus reviewed the epidemiology, pathogenesis, potential predisposing factors, clinical manifestations, diagnosis, differential diagnosis, treatment, and prognosis of cemental tear, aiming to provide a clinical guideline and facilitate clinicians to have a better understanding of cemental tear.

By using paddy rice harvested between 2019 and 2023 as the research object,the volatile components of rice grains were detected by headspace solid-phase microextraction coupled with gas chromatography-triple quadrupole mass spectrometry.Qualitative analysis of the compounds was complemented by a standard mass spectrometry database and retention index,while a selected ion monitoring approach was established to quantify the contents of each component through the internal standard method.Multivariate statistical analyses including principal component analysis and orthogonal partial least squares discriminant analysis were employed to identify differential compounds related to freshness of the paddy rice.Subsequently,a classification model for identifying stored paddy rice based on volatile component analysis was developed.A total of 44 kinds of volatile compounds were identified across different harvest years,including aldehydes,alcohols,ketones,acids,esters,phenols and furans.The results of the multivariate statistical analysis revealed that the content-based orthogonal partial least squares discriminant analysis model could effectively distinguish 2023 harvested paddy rice from those harvested between 2019 and 2022 into two distinct categories.Notably,compounds such as hexanoic acid and nonanoic acid along with twelve others were identified as differential compounds based on variable improtance in projection(VIP)values exceeding 1 and p values less than 0.05.The classification model established through volatile component analysis was expected to provide a theoretical foundation for assessing the freshness of stored paddy rice.
