Abstract
The pathogenesis of granulomatous rosacea (GR), the only variant of rosacea, is unclear. To investigate the differences between GR and non-granulomatous rosacea (NGR) in clinical characteristics, histopathological changes and gene expression for the purpose of providing new ideas on the pathogenesis of rosacea. A total of 30 GR and 60 NGR patients were included. Their clinical and histopathological information was collected retrospectively, and the characteristics of immune cell infiltration were investigated by multiple immunohistochemical staining. RNA sequencing and transcriptome analysis were performed on three pairs of skin samples from GR and NGR patients, respectively. Then, the expressions of candidate genes that were potentially associated with granuloma formation were verified by immunohistochemical staining. It was found that GR patients were more prone to the occurrence of rosacea in the forehead, periocular and perioral skin (p = 0.001, p < 0.001, p = 0.001), and presented more severe papules and pustules when compared with NGR patients (p = 0.032). For histopathological features, the inflammatory cells primarily infiltrated around hair follicles in the GR group and around blood vessels in the NGR group. In addition, the neutrophils were richer (p = 0.036) and the expression levels of CD4+ , CD8+ and CD68+ cells were higher (p = 0.047, p < 0.001, p < 0.001) in the GR group than in the NGR group. In addition, the GR group had apparent collagen hyperplasia (p = 0.026). A total of 420 differentially expressed genes (DEGs) were detected, and bioinformatics analysis showed that the DEGs were enriched in neutrophil activation, adaptive immune response and other biological processes. Lastly, the candidate genes related to neutrophil activation and collagen hyperplasia, i.e., Cathepsin S (CTSS), Cathepsin Z (CTSZ) and matrix metalloproteinases 9 (MMP9), were confirmed to be highly expressed in the GR group. The clinical and histopathological features of GR exhibited a very diverse pattern compared with NGR, and the underlying mechanisms may be related to neutrophil activation and collagen hyperplasia.

Abstract
Purpose To explore the predictive value of computed tomography (CT) imaging features and CT-based texture analysis in assessing inflammatory infiltration in pancreatic ductal adenocarcinoma (PDAC). Methods A total of 43 patients with PDAC confirmed by surgical pathology were included in the study. The clinical, radiological, surgical, and pathological features of the patients were analyzed retrospectively using the chi-square test or Spearman's correlation. Receiver operating characteristic (ROC) curves were utilized to assess the overall predictive ability of the tumor enhancement degree on triphasic contrast-enhanced CT images for the inflammatory infiltration degree in PDAC. Furthermore, all CT data were uploaded to the RadCloud platform for region of interest (ROI) delineation and feature extraction. Then, the Variance Threshold and SelectKBest algorithms were used to find the optimal CT features. Binary logistic regression was employed to analyze the selected features in all three contrast-enhanced CT phases, and regression equations were formulated. ROC analysis was performed to evaluate the predictive effectiveness of each equation. Results The analysis revealed a statistically significant correlation between the degree of differentiation and radiological findings such as necrosis and cystic degeneration, vascular invasion, and the presence of ascites (P < 0.05). The enhancement degree of the tumor in both the arterial and venous phases was significantly correlated with the inflammatory infiltration degree (P < 0.05); however, the areas under the ROC curve (AUCs) of arterial and venous enhancement were 0.570 and 0.542, respectively. Regression equations based on the texture features of triphasic contrast-enhanced tumors were formulated, and their AUCs were 0.982, 0.643, and 0.849. Conclusion Conventional radiological features are not significantly correlated with the degree of inflammatory infiltration in PDAC. The enhancement degrees in both the arterial phase and venous phase were statistically correlated with the inflammatory infiltration level but had poor predictive value. The texture features of PDAC on contrast-enhanced CT may show a better assessment value, especially in the arterial phase.

Abstract
Type 2 diabetes mellitus (T2DM) is a metabolic risk factor associated with non‐alcoholic liver disease (NAFLD). Schisandrin B (Sch B) is a promising agent for NAFLD. However, the actions of Sch B on diabetes‐associated NAFLD and the underlying mechanisms are not characterized. This study aimed to assess whether Sch B has beneficial effects on T2DM‐associated NAFLD. Sch B (50 mg/kg, gavage) was administrated to C57BL/KSJ db/db mice for 2 weeks. Body weight, liver weight, blood glucose, and insulin resistance were measured. Serum lipid level and liver function were detected using the biochemistry analyzer. Quantitative Real‐Time PCR assay was used to evaluate mRNA levers of lipid metabolism genes. Terminal‐deoxynucleoitidyl Transferase Mediated Nick End Labeling (TUNEL) staining was performed to measure apoptosis in the liver. Pathological analysis and immunohistochemistry assessment were used to analyze hepatic steatosis and inflammatory infiltration. Sch B supplementation significantly decrease body weight, related liver weight, blood glucose, and serum insulin, and improved insulin resistance in db/db mice. Sch B obviously corrected NAFLD phenotypes including lipid deposition, steatohepatitis, and high levels of hepatic enzymes and serum lipid. In addition, mRNA levels of Sterol response element‐bind protein 1c (SREBP‐1c), fatty acid synthetase (Fasn), and acetyl‐CoA carboxylase (ACC) were markedly downregulated by Sch B treatment. TUNEL‐positive cells were also decreased by Sch B. Furthermore, Sch B inhibited the Kupffer cells, IL‐1β, and TNF‐α infiltration to the liver. Sch B ameliorated insulin resistance and lipid accumulation under high glucose conditions, which was partly associated with its inhibition of apoptosis and anti‐inflammatory actions.

Abstract
Oral candidiasis is one of the most common types of fungal infection caused by Candida albicans (C. albicans). The present study aims to investigate the antifungal effects of phloretin (a dihydrochalcone flavonoid) against the C. albicans pathogenicity. In this work, we treated C. albicans SC5314 with 37.28, 74.55, or 149.10 μg/mL (equivalent to 0.5×, 1× or 2× MIC) phloretin in vitro. Besides, we established a mice model of oral candidiasis by a sublingual infection of C. albicans suspension (1 × 107 colony-forming unit/mL), and mice were treated with phloretin (3.73 or 7.46 mg/mL, which were equivalent to 50× or 100× MIC) twice a day starting on day one post-infection. The results showed that the MIC of phloretin against C. albicans was 74.55 μg/mL. Phloretin exerted antifungal activity by inhibiting the biofilm formation and suppressing the yeast-to-hyphae transition upon the downregulation of hypha-associated genes including enhanced adherence to polystyrene 1, the extent of cell elongation gene 1, hyphal wall protein 1 gene, and agglutinin-like sequence gene 3. Next, phloretin repressed the secretion of proteases and phospholipases via reducing the expression of protease-encoding genes secreted aspartyl proteases (SAP)1 and SAP2, as well as phospholipase B1. Subsequently, the in vivo antifungal activity of phloretin was testified by the reverse of the enhanced lesion severity, inflammatory infiltration, and the increased colony-forming unit counts caused by C. albicans of tongue tissues in oral candidiasis mice. In conclusion, phloretin suppressed the pathogenicity and virulence factors against C. albicans both in vivo and in vitro.

Abstract
BACKGROUND In chronic kidney disease, the activation of the renin-angiotensin-aldosterone system (RAAS) and renal inflammation stimulates renal fibrosis and the progression to end-stage renal disease. The low levels of vitamin D receptor (VDR) and its activators (VDRAs) contribute to worsen secondary hyperparathyroidism and renal fibrosis. METHODS The 7/8 nephrectomy model of experimental chronic renal failure (CRF) was used to examine the anti-fibrotic effects of treatment with two VDRAs, paricalcitol and calcitriol, at equivalent doses (3/1 dose ratio) during 4 weeks. RESULTS CRF increased the activation of the RAAS, renal inflammation and interstitial fibrosis. Paricalcitol treatment reduced renal collagen I and renal interstitial fibrosis by decreasing the activation of the RAAS through renal changes in renin, angiotensin receptor 1 (ATR1) and ATR2 mRNAs levels and renal inflammation by decreasing renal inflammatory leucocytes (CD45), a desintegrin and metaloproteinase mRNA, transforming growth factor beta mRNA and protein, and maintaining E-cadherin mRNA levels. Calcitriol showed similar trends without significant changes in most of these biomarkers. CONCLUSIONS Paricalcitol effectively attenuated the renal interstitial fibrosis induced by CRF through a combination of inhibitory actions on the RAAS, inflammation and epithelial/mesenchymal transition.

Abstract
OBJECTIVE Myocardial ischemia reperfusion (MI/RI) stresses the pathological process of progressive aggravation of tissue damage in ischemic myocardium. Isoflurane (ISO) is cardioprotective in MI/RI. Thus, this work aimed to identify the mechanism of isoflurane (ISO) post-treatment in MI/RI by regulating microRNA-378 (miR-378) and mitogen-activated protein kinase 1 (MAPK1). METHODS A MI/RI model was established by ligating the left anterior descending coronary artery in mice. The modeled mice were injected with ISO or miR-378 or MAPK1 to define their roles in hemodynamics, myocardial injury, cell apoptosis and inflammatory infiltration of mice. CD45, miR-378 and MAPK1 levels were detected. Dual luciferase reporter gene assay was utilized for detection of the targeting connection of miR-378 and MAPK1. RESULTS Reduced miR-378 and elevated MAPK1 existed in MI/RI. ISO elevated miR-378 to target MAPK1. ISO improved hemodynamics and myocardial injury, reduced apoptosis rate and inflammatory infiltration in MI/RI mice. Up-regulated miR-378 further enhanced the protective effect of ISO on MI/RI mice. Depleting MAPK1 reversed the effects of suppressed miR-378 on MI/RI. CONCLUSION This study highlights that elevating miR-378 strengthens the isoflurane-mediated effects on MI/RI in mice via suppressing MAPK1, which provides a potential treatment for MI/RI.

Abstract
The aim of the present study was to investigate the effects of diammonium glycyrrhizinate lipid ligand (DGLL) treatment on acute lung injury (ALI) and pulmonary edema induced by lipopolysaccharide (LPS) in Sprague-Dawley rats. Rats orally received 30, 60 and 120 mg/kg DGLL. After 1 h, the rat ALI model was established by LPS (10 mg/kg) intraperitoneal injection. After 6 h, lung injury was evaluated using hematoxylin and eosin staining techniques. Pulmonary edema was evaluated using lung wet-dry weight ratio, protein concentrations in the bronchoalveolar lavage fluid (BALF) and Evans blue (EB) extravasation in lung tissue. The expression levels of tumor necrosis factor (TNF)-α and interleukin (IL)-1β in lung tissues were measured using ELISA. Myeloperoxidase (MPO) expression levels were detected by immunohistochemical staining. Western blotting was used to measure the expression level changes of intercellular adhesion molecule (ICAM)-1, as well as adherent and tight junction proteins, including vascular endothelial (VE)-cadherin, zonula occludens (ZO)-1, occludin and junctional adhesion molecule (JAM)-1 that were associated with pulmonary inflammation and microvascular permeability. DGLL treatment significantly alleviated ALI induced by LPS, which was demonstrated by reduction of MPO-positive cells and expression levels of TNF-α, IL-1β and ICAM-1 in rat lung tissues. In addition, DGLL abrogated LPS-induced pulmonary edema, decreased the protein concentration in BALF and reduced EB extravasation. DGLL also reversed the reduced expression of VE-cadherin and tight junction proteins, including ZO-1, occludin and JAM-1 in the lung tissues caused by LPS. In conclusion, DGLL exhibits a protective effect on LPS-induced rat ALI, which is associated with the inhibition of inflammatory cell infiltration and microvascular barrier disruption. The present results provide a theoretical basis for the application of DGLL for the potential clinical treatment of ALI.

Abstract
The aim of the present study was to investigate the MRI and pathological features of Rathke cleft cysts (RCC) in the sellar region. A total of 45 RCC cases were retrospectively analyzed. RCC size, location, intracyst nodules and general signals, as well as the posterior pituitary bright spot (PPBS) were analyzed using MRI-T1 weighted images (T1WI) and T2WI. The relationship between the presence of PPBS and histopathological features was additionally evaluated. On T1WI, there were 18 cases of isointense signal, 16 cases of hyperintense signal, 9 cases of hypointense signal, 1 case of heterogeneous signal and 1 case with a stratification effect, with isointense signal in the upper part and hyperintense signal in the lower part. On T2WI, there were 5 cases of isointense signal, 27 cases of hyperintense signal, 11 cases of hypointense signal and 1 case of the stratification effect. There were 10 cases of PPBS+ and 35 cases of PPBS-. There were no significant differences in the age, sex, cyst location and size between PPBS+ and PPBS- cases. However, PPBS+ cases had significantly lower inflammation than PPBS- cases. A total of 20 cases of intracystic nodules were identified on MRI scans, most of which exhibited T2 -hypointense signals. The shape of RCC nodules varied and there were 17 cases where the nodules were non-adherent to the cyst wall. The MRI signals of RCCs varied and most nodules were floating within cysts. Intracystic nodules are characteristic features of RCCs when observed by MRI and thus are of high diagnostic value. Most patients with RCC were also PPBS-, which may be associated with an increased inflammatory response.

Abstract
Animal models play critical roles in exploring the pathogenesis of human diseases and designing novel therapeutic schemes. Acute experimental colitis (AEC) models have been reported to be established in mice principally by oral administration of dextran sulfate sodium (DSS). However, little knowledge is known about whether DSS can be used to induce the acute experimental enteritis (AEE). In this study, different concentrations of DSS (0%, 2%, 3%, and 5%) were used to induce AEC and AEE models in two cohorts. After the establishment of these two models, the symptoms of the mice induced by DSS were noted, the length and average weight of each colon and small intestine were measured, and hematoxylin and eosin (HE) staining was conducted for assessing the inflammatory infiltration in these models. Generally, the comparison of the inflammatory scoring between AEC and AEE models was analyzed. As a consequence, we found that, the mice with 2%-5% DSS administration in a week could develop into AEC models in two cohorts and AEE models in one cohort, followed by the signs of diarrhea, gross rectal bleeding, weight loss of the body, and shortened colon and intestine length, as compared with the control group. HE staining showed that the inflammatory scoring was dramatically increased by 3%-5% DSS in AEC models in two cohorts but slightly elevated in AEE models in one cohort. Meanwhile, as compared with the severe AEC models, the extent of inflammatory infiltration induced by 3%-5% DSS in AEE models was much milder. In conclusion, oral administration of 3%-5% DSS is a good inducer of AEC models, but not AEE models.

Abstract
Autoimmune pancreatitis (AP) is a rare autoimmune pancreatic manifestation of systemic immunoglobulin G4 (IgG4)-related sclerosing disease. Distinguishing between AP and pancreatic cancer is crucial because the clinical courses, treatments, and prognoses of these two disease entities are quite different. We herein report a case involving a 52-year-old man with subacute epigastralgia who visited our hospital for evaluation of a suspicious pancreatic mass found during esophagogastroduodenoscopy. Enhanced computed tomography (CT) revealed an enlarged lesion in the pancreatic head with encasement of hepatic vessels. The lesion also exhibited increased 18F-fluorodeoxyglucose accumulation on positron emission tomography/CT imaging, which was highly suggestive of pancreatic cancer. After open biopsy, morphologic examination showed an inflammatory infiltrate in the pancreas, which was compatible with chronic sclerotic pancreatitis. Further laboratory tests revealed an elevated serum IgG4 level, and the diagnosis of sclerotic pancreatitis was then confirmed. After corticosteroid treatment, the pancreatic lesion showed shrinkage on follow-up CT, and the serum IgG4 titer decreased to the normal range. This case suggests that clinicians should be familiar with the clinical presentations and diagnostic criteria of AP versus pancreatic cancer. An awareness of the differences between these diseases may avoid misdiagnosis and unnecessary surgical intervention.

Abstract
The aim of this study was to evaluate the effect of intralesional tamoxifen on keloids, particularly on the concentration of fibroblasts, dermal inflammatory infiltrate, and collagen degeneration. A prospective study was carried out to evaluate keloids in 13 patients of both genders pre- and post-treatment with intralesional tamoxifen. Two samples of keloid lesions were obtained by 4-mm punch biopsies during the study: the first at the time of diagnostic confirmation of keloid and the other eight weeks later at the end of intralesional tamoxifen treatment. The biopsy samples were placed in 10% buffered formalin for HE staining and morphological and morphometric study. The degree of collagen fiber reduction and inflammatory infiltration were analyzed. Student's t-test was used for statistical analysis of the mean number of fibroblasts before and following tamoxifen treatment ( P < 0.05). The degree of collagen fiber reduction and inflammatory infiltration were absent before treatment and present in 100% of cases after treatment, while the mean number of fibroblasts was significantly lower after intralesional tamoxifen treatment ( P < 0.0001). We conclude that intralesional administration of tamoxifen promoted an inflammatory stimulus and collagen fiber reduction as well as a significant reduction in the number of fibroblasts that produce collagen. Impact statement Effective treatment of keloid that is a commonly recurrent dermatosis is very difficult, even after standard treatment. Standard treatment consists of partial resection of the lesion (shaving excision), in addition to local corticosteroid injection. Therefore, there is interest in alternative forms of topical treatment, e.g., selective estrogen receptor modulators, particularly tamoxifen has demonstrated in vitro studies to be a promising drug. Nevertheless, there is scarcity of publications on the effects of intralesional tamoxifen on keloids have been found, leading us to the conception of the present study. In this study, tamoxifen has proven to be an interesting alternative drug for the topical treatment of keloid, allowing us to conclude that the intralesional application of tamoxifen in keloids promotes a variable but ever-present inflammatory stimulus, associated with intense reduction of collagen fiber, in addition to a significant decrease in the number of fibroblasts that produce collagen and are involved in disease maintenance.
