This study employed bioinformatics to screen the feature genes related to efferocytosis in diabetic kidney disease(DKD) and explores traditional Chinese medicine(TCM) regulating these feature genes. The GSE96804 and GSE30528 datasets were integrated as the training set, and the intersection of differentially expressed genes and efferocytosis-related genes(ERGs) was identified as DKD-ERGs. Subsequently, correlation analysis, protein-protein interaction(PPI) network construction, enrichment analysis, and immune infiltration analysis were performed. Consensus clustering was conducted on DKD patients based on the expression levels of DKD-ERGs, and the expression levels, immune infiltration characteristics, and gene set variations between different subtypes were explored. Eight machine learning models were constructed and their prediction performance was evaluated. The best-performing model was evaluated by nomograms, calibration curves, and external datasets, followed by the identification of efferocytosis-related feature genes associated with DKD. Finally, potential TCMs that can regulate these feature genes were predicted. The results showed that the training set contained 640 differentially expressed genes, and after intersecting with ERGs, 12 DKD-ERGs were obtained, which demonstrated mutual regulation and immune modulation effects. Consensus clustering divided DKD into two subtypes, C1 and C2. The support vector machine(SVM) model had the best performance, predicting that growth arrest-specific protein 6(GAS6), S100 calcium-binding protein A9(S100A9), C-X3-C motif chemokine ligand 1(CX3CL1), 5'-nucleotidase(NT5E), and interleukin 33(IL33) were the feature genes of DKD. Potential TCMs with therapeutic effects included Astragali Radix, Trionycis Carapax, Sargassum, Rhei Radix et Rhizoma, Curcumae Radix, and Alismatis Rhizoma, which mainly function to clear heat, replenish deficiency, activate blood, resolve stasis, and promote urination and drain dampness. Molecular docking revealed that the key components of these TCMs, including β-sitosterol, quercetin, and sitosterol, exhibited good binding activity with the five target genes. These results indicated that efferocytosis played a crucial role in the development and progression of DKD. The feature genes closely related to both DKD and efferocytosis, such as GAS6, S100A9, CX3CL1, NT5E, and IL33, were identified. TCMs such as Astragali Radix, Trionycis Carapa, Sargassum, Rhei Radix et Rhizoma, Curcumae Radix, and Alismatis Rhizoma may provide a new therapeutic strategy for DKD by regulating efferocytosis.

Recent advances in multimodality treatment offer excellent opportunities to rethink the paradigm of perioperative management for locally advanced esophageal squamous cell carcinoma. One treatment clearly doesn't fit all in terms of a broad disease spectrum. Individualized treatment of local control of bulky primary tumor burden (advanced T stage) or systemic control of nodal metastatic tumor burden (advanced N stage) is essential. Given that clinically applicable predictive biomarkers are still awaited, therapy selection guided by diverse phenotypes of tumor burden (T vs. N) is promising. Potential challenges regarding the use of immunotherapy may also boost this novel strategy in the future.

Objective: To evaluate the diagnostic value of transient elastography, aspartate aminotransferase-to-platelet ratio index (APRI), and fibrosis index based on 4 factors (FIB-4) for liver fibrosis in children with non-alcoholic fatty liver disease (NAFLD). Methods: A retrospective study was conducted on 100 cases of nonalcoholic fatty liver disease in Hunan Children's Hospital between August 2015 to October 2020 to collect liver tissue pathological and clinical data. The receiver operating characteristic curve (ROC curve) was used to analyze the diagnostic value of liver stiffness measurement (LSM), APRI and FIB-4 in the diagnosis of different stages of liver fibrosis caused by NAFLD in children. Results: The area under the ROC curve (AUC) value of LSM, APRI and FIB-4 for diagnosing liver fibrosis (S≥1) were 0.701 [95% confidence interval (CI): 0.579 ~ 0.822, P = 0.011], 0.606 (95%CI: 0.436 ~ 0.775, P = 0.182), and 0.568 (95%CI: 0.397 ~ 0.740, P = 0.387), respectively. The best cut-off values were 6.65 kPa, 21.20, and 0.18, respectively. The AUCs value of LSM, APRI, and FIB-4 for diagnosing significant liver fibrosis (S≥ 2) were 0.660 (95% CI: 0.552 ~ 0.768, P = 0.006), 0.578 (95% CI: 0.464 ~ 0.691, P = 0.182) and 0.541 (95% CI: 0.427 ~ 0.655, P = 0.482), respectively. The best cut-off values were 7.35kpa, 24.78 and 0.22, respectively. The AUCs value of LSM, APRI and FIB-4 for the diagnosis of advanced liver fibrosis (S≥ 3) were 0.639 (95% CI: 0.446 ~ 0.832, P = 0.134), 0.613 (95% CI: 0.447 ~ 0.779, P = 0.223) and 0.587 (95% CI: 0.411 ~ 0.764, P = 0.346), respectively. The best cut-off values were 8.55kpa, 26.66 and 0.27, respectively. Conclusion: The transient elastography technique has a better diagnostic value than APRI and FIB-4 for liver fibrosis in children with NAFLD.

The naphthaquinones are widely distributed in plants. They are usually in higher plants, but a few of them were also found in microorganisms. There is a lot of research showing that they had multiple pharmaco-activities such as cytotoxic, antioxidant, anti-inflammatory and antibacterial activities, etc. In recent years, they have attracted extensive attention at home and abroad especially in terms of the anti-tumor activity. For further research, 69 new natural naphthoquinones reported in the last five years (2013-2017) were reviewed. They were divided into five major types: simple 1,4-naphthoquinones, furan and pyran naphthoquinones, 1,2-naphthoquinones, naphthohydroquinones and naphthoquinone polymers, which showed cytotoxic, antioxidative, anti-inflammatory and antibacterial biological activities, et al. The research of these compounds in the future was also proposed.

OBJECTIVETo explore the molecular mechanism of exocrine immune inflammatory injury of Sjögren's Syndrome and the intervention of Banxia Qinlian Decoction (BQD).

METHODSTotally 18 female NOD mice were randomly divided into the model group, the positive drug group, and the BQD group, 6 in each group. Six female BALB/c mice were recruited as a blank control group. Mice in the blank control group and the model group were gavaged with deionized water at the daily dose of 0.1 mL/10 g body weight. Tripterygium Tablet was administered by gastrogavage to mice in the positive group at the daily dose of 10 mg/kg. BQD was administered by gastrogavage to mice in the BQD group at the daily dose of 60 g crude drugs/kg. After 12 weeks of medication, mice were sacrificed. Their eyeballs were excised and blood collected. Tissues of bilateral parotids and submandibular glands were kept. mRNA transcriptional levels of IL-17, IL-6, type 3 muscarinic acetylcholine receptors (M3R), aquaporin protein-5 (AQP5) were detected by RT-PCR. Expression levels of M3R and AQP5 protein were detected by Western blot. Protein expression levels of IL-17 and IL-6 were detected by ELISA.

RESULTSCompared with the normal group, mRNA transcriptional levels and protein expression levels of IL-17, IL-6, M3R, and AQP5 were significantly up-regulated in the model group (P < 0.01). Compared with the model group, mRNA transcriptional levels and protein expression levels of IL-17, IL-6, M3R, and AQP5 were significantly down-regulated in the positive drug group and the BQD group with statistical difference (P < 0.01, P < 0.05). Compared with the BQD group, mRNA-transcriptional levels of IL-17, IL-6, and M3R, as well as M3R and AQP5 protein expression levels were significantly down-regulated in the positive drug group (all P < 0.01).

CONCLUSIONThe molecular mechanism of BQD in inhibiting SS exocrine neurotoxic injury might be possibly related to regulating Th17/IL-17 immune inflammatory way.
