ObjectiveTo explore the pharmacological mechanism involved in the treatment of allergic cough (AC) by Xiaoer Huatan Zhike granules (XEHT) based on proteomics and network pharmacology. MethodsAfter sensitization by intraperitoneal injection of 1 mL suspension containing 2 mg ovalbumin (OVA) and 100 mg aluminum hydroxide, a guinea pig model of allergic cough was constructed by nebulization with 1% OVA. The modeled guinea pigs were randomized into the model, low-, medium- and high-dose (1, 5, 20 g·kg-1, respectively) XEHT, and sodium montelukast (1 mg·kg-1) groups (n=6), and another 6 guinea pigs were selected as the blank group. The guinea pigs in drug administration groups were administrated with the corresponding drugs by gavage, and those in the blank and model groups received the same volume of normal saline by gavage, 1 time·d-1. After 10 consecutive days of drug administration, the guinea pigs were stimulated by 1% OVA nebulization, and the coughs were observed. The pathological changes in the lung tissue were observed by hematoxylin-eosin staining. The enzyme-linked immunosorbent assay was performed to measure the levels of C-reactive protein (CRP), interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), superoxide dismutase (SOD), and malondialdehyde (MDA) in the bronchoalveolar lavage fluid (BALF) and immunoglobulin G (IgG) and immunoglobulin A (IgA) in the serum. Immunohistochemistry (IHC) was employed to observe the expression of IL-6 and TNF-α in the lung tissue. Transmission electron microscopy was employed observe the alveolar type Ⅱ epithelial cell ultrastructure. Real-time PCR was employed to determine the mRNA levels of IL-6, interleukin-1β (IL-1β), and TNF-α in the lung tissue. Label-free proteomics was used to detect the differential proteins among groups. Network pharmacology was used to predict the targets of XEHT in treating AC. The Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis was performed to search for the same pathways from the results of proteomics and network pharmacology. ResultsCompared with the blank group, the model group showed increased coughs (P<0.01), elevated levels of CRP, TNF-α, IL-6, and MDA and lowered level of SOD in the BALF (P<0.05, P<0.01), elevated levels of IgA and IgG in the serum (P<0.05, P<0.01), congestion of the lung tissue and infiltration of inflammatory cells, increased expression of IL-6 and TNF-α (P<0.01), large areas of low electron density edema in type Ⅱ epithelial cells, obvious swelling and vacuolization of the organelles, karyopyknosis or sparse and dissolved chromatin, and up-regulated mRNA levels of IL-6, IL-1β, and TNF-α (P<0.01). Compared with the model group, the drug administration groups showed reduced coughs (P<0.01), lowered levels of CRP, TNF-α, IL-6, and MDA and elevated level of SOD in the BALF (P<0.05, P<0.01), alleviated lung tissue congestion, inflammatory cell infiltration, and type Ⅱ epithelial cell injury, and decreased expression of IL-6 and TNF-α (P<0.01). In addition, the medium-dose XEHT group and the montelukast sodium group showcased lowered serum levels of IgA and IgG (P<0.05, P<0.01). The medium- and high-dose XEHT groups and the montelukast sodium showed down-regulated mRNA levels of IL-6, IL-1β, and TNF-α and the low-dose XEHT group showed down-regulated mRNA levels of IL-6 and TNF-α (P<0.05, P<0.01). Phospholipase D, mammalian target of rapamycin (mTOR), and epidermal growth factor receptor family of receptor tyrosine kinase (ErbB) signaling pathways were the common pathways predicted by both proteomics and network pharmacology. ConclusionProteomics combined with network pharmacology reveal that XEHT can ameliorate AC by regulating the phospholipase D, mTOR, and ErbB signaling pathways.

[Objective] To explore the risk factors of postoperative fever in primary aldosteronism (PA) patients. [Methods] Clinical data of 116 PA patients undergoing adrenalectomy in Peking University People's Hospital during Jan.2018 and Jul.2021 were retrospectively analyzed.Based on postoperative body temperature, the patients were divided into fever group (body temperature ≥38.0 ℃, n=41) and non-fever group (body temperature <38.0 ℃, n=75). Clinical features were analyzed between the two groups.The fever group was subdivided into low fever group (38.0 ℃≤body temperature <38.5 ℃, n=19) and high fever group (body temperature ≥38.5 ℃, n=22). The clinical data of the subgroups were compared. [Results] The incidence of postoperative fever was 35.3%.Logistic regression analysis showed that lower lowest potassium on records (OR=0.419, 95%CI: 0.196-0.894, P=0.025), lower high-density lipoprotein cholesterol (HDL-C) (OR=0.112, 95%CI: 0.018-0.687, P=0.018), and postoperative adrenal insufficiency (OR=4.158, 95%CI: 1.731-9.989, P=0.001) were independent risk factors for postoperative fever.There was no difference between the high and low fever groups.After surgery, infection occurred in 1 patient, adrenal insufficiency in 40 (34.5%) patients, but long-term follow-up indicated that no patients needed lifelong glucocorticoid replacement. [Conclusion] Fever is a common postoperative complication in PA patients, most likely due to transient adrenal insufficiency.Glucocorticoid supplementation should be administered appropriately and timely based on laboratory tests and clinical manifestations.Evaluation of adrenal function is highly recommended for patients undergoing adrenalectomy.

Objective To systematically evaluate the risk prediction model of anastomotic fistula after radical resection of esophageal cancer, and to provide objective basis for selecting a suitable model. Methods A comprehensive search was conducted on Chinese and English databases including CNKI, Wanfang, VIP, CBM, PubMed, EMbase, Web of Science, The Cochrane Library for relevant studies on the risk prediction model of anastomotic fistula after radical resection of esophageal cancer from inception to April 30, 2023. Two researchers independently screened literatures and extracted data information. PROBAST tool was used to assess the risk of bias and applicability of included literatures. Meta-analysis was performed on the predictive value of common predictors in the model with RevMan 5.3 software. Results A total of 18 studies were included, including 11 Chinese literatures and 7 English literatures. The area under the curve (AUC) of the prediction models ranged from 0.68 to 0.954, and the AUC of 10 models was >0.8, indicating that the prediction performance was good, but the risk of bias in the included studies was high, mainly in the field of research design and data analysis. The results of the meta-analysis on common predictors showed that age, history of hypertension, history of diabetes, C-reactive protein, history of preoperative chemotherapy, hypoproteinemia, peripheral vascular disease, pulmonary infection, and calcification of gastric omental vascular branches are effective predictors for the occurrence of anastomotic leakage after radical surgery for esophageal cancer (P<0.05). Conclusion The study on the risk prediction model of anastomotic fistula after radical resection of esophageal cancer is still in the development stage. Future studies can refer to the common predictors summarized by this study, and select appropriate methods to develop and verify the anastomotic fistula prediction model in combination with clinical practice, so as to provide targeted preventive measures for patients with high-risk anastomotic fistula as soon as possible.

ObjectiveTo investigate the effect and potential mechanism of caffeic acid (CA) on severe acute pancreatitis (SAP) induced by caerulein combined with lipopolysaccharide (LPS), and to provide a basis for the research on novel drugs for the treatment of SAP. MethodsC57BL/6J mice, aged 6 weeks, were divided into control group, model group, CA group, and octreotide acetate (OA) group, with 6 mice in each group. The mice in the control group were given injection of normal saline, and those in the other groups were given intraperitoneal injection of caerulein combined with LPS to establish a mouse model of SAP. At 1 hour after the first injection of caerulein, the mice in the CA group and the OA group were given intraperitoneal injection of CA or subcutaneous injection of OA at an interval of 8 hours. The general status of the mice was observed after 24 hours of modeling, and serum, pancreas, lung, and colon samples were collected. HE staining was used to observe the histopathological changes of the pancreas and lungs, and the serum levels of α-amylase, lipase, tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), alanine aminotransferase, aspartate aminotransferase, and creatinine were measured. RT-PCR was used to measure the expression of proinflammatory factors in the pancreas and lungs; myeloperoxidase (MPO) immunohistochemistry was used to observe the degree of neutrophil infiltration; Western blot was used to measure the activation of nuclear factor-kappa B (NF-κB) and the level of citrullinated histone H3 (CitH3), a marker for the formation of neutrophil extracellular traps (NETs), in the pancreas and lungs, as well as the expression level of ZO-1 in colon tissue. A one-way analysis of variance was used for comparison of continuous data between multiple groups, and the Dunnett’s t-test was used for further comparison between two groups. ResultsCompared with the control group, the model group had severe injury in the pancreas and lungs and significant increases in the activity of serum α- amylase and lipase and the levels of the proinflammatory cytokines IL-6, interleukin-1β (IL-1β), and TNF-α in serum and lung tissue (all P<0.05), as well as significant increases in NF-κB activation, neutrophil infiltration, and the formation of NETs in the pancreas and lungs (all P<0.05). Compared with the model group, the CA group had alleviated pathological injury of the pancreas and lungs and significant reductions in the activity of serum α-amylase and the levels of the proinflammatory cytokines IL-6, IL-1β, and TNF-α in serum and lung tissue (all P<0.05), as well as significant reductions in NF-κB activation, neutrophil infiltration, and the formation of NETs in the pancreas and lungs (all P<0.05). ConclusionCA can alleviate SAP induced by caerulein combined with LPS in mice, possibly by inhibiting neutrophil recruitment and the formation of NETs.

Recent clinical studies have shown that mutation of phosphatase and tensin homolog deleted on chromosome 10 (PTEN) gene in cancer cells may be associated with immunosuppressive tumor microenvironment (TME) and poor response to immune checkpoint blockade (ICB) therapy. Therefore, efficiently restoring PTEN gene expression in cancer cells is critical to improving the responding rate to ICB therapy. Here, we screened an adeno-associated virus (AAV) capsid for efficient PTEN gene delivery into B16F10 tumor cells. We demonstrated that intratumorally injected AAV6-PTEN successfully restored the tumor cell PTEN gene expression and effectively inhibited tumor progression by inducing tumor cell immunogenic cell death (ICD) and increasing immune cell infiltration. Moreover, we developed an anti-PD-1 loaded phospholipid-based phase separation gel (PPSG), which formed an in situ depot and sustainably release anti-PD-1 drugs within 42 days in vivo. In order to effectively inhibit the recurrence of melanoma, we further applied a triple therapy based on AAV6-PTEN, PPSG@anti-PD-1 and CpG, and showed that this triple therapy strategy enhanced the synergistic antitumor immune effect and also induced robust immune memory, which completely rejected tumor recurrence. We anticipate that this triple therapy could be used as a new tumor combination therapy with stronger immune activation capacity and tumor inhibition efficacy.

Objective To explore the effects of HPV16 E6 on genes and signaling pathways in cervical epithelial cells and to screen genes associated with oncogenic transformation.Methods HUCEC models infected with HPV16 E6 were constructed,and transcriptome sequencing was performed to screen for differentially expressed genes(DEGs),which were subjected to Gene Ontology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG)enrichment to analyze the differential signaling pathways.RT-qPCR was used to validate major differentially down-regulated expressed genes.After predicting the major differentially expressed proteins by molecular docking analysis,the expression of major differential genes in HUCEC cell model was verified by RT-qPCR and Western blotting.In addition,RT-qPCR and Western blotting were used to further verify the expression of major differential genes in cervical cancer cell lines,SiHa and CaSki.Results A total of 55 genes with more than two-fold differential expression were screened.The results centering on down-regulated genes showed that the negatively regulated differential gene was mainly enriched in redox processes;KEGG enrichment analysis revealed that it was mainly associated with carbohydrate metabolism and cancer.RT-qPCR results showed that the down-regulated differential expression trends of the selected 10 genes were basically consistent with the sequencing results.Molecular docking analysis predicted an interaction between DHRS2 and HPV16 E6,and RT-qPCR and Western blotting confirmed that HPV16 E6 down-regulated DHRS2 mRNA(P<0.01)and protein(P<0.05)and ETV5 protein expression(P<0.01).In SiHa and CaSki cells,compared with the control group,the mRNA and protein expression of DHRS2 was downregulated and positively correlated with the trend of P53 protein expression(P<0.05).Conclusion HPV16 E6 can mediate oncogenic transformation of cervical cells and promote cervical carcinogenesis through downregulating DHRS2 expression.
