Postprandial drowsiness is a clinical condition characterized by pronounced drowsiness after meals， while The Inner Canon of Yellow Emperor （《黄帝内经》） associates this condition with wei qi （defensive qi）. By analyzing the original texts of The Inner Canon of Yellow Emperor and perspectives from many medical professionals， it is found that the transition between wakefulness and sleep depends on the mutual induction of yin and yang， and that the two pathways of wei qi circulation intersect at the spleen and stomach. Based on this， the core pathogenesis of postprandial drowsiness is proposed to be either upper jiao obstruction or spleen-stomach dysfunction， leading to the stagnation of wei qi internally， then the mutual induction of yin and yang causes inward invasion of wei qi in the body， resulting in drowsiness； at this stage， the stagnated and inward invasive wei qi converges at the spleen and stomach， then merges into the circulation of zang-fu organs， rerouting through the Foot Taiyang Meridian， forming a circulation pattern described as "circulating from yin to yang". Treatment should focus on the root and branch simultaneously， with the primary goal of regulating the circulation of wei qi； facilitating its transition from yin to yang to restore the sleep-wake cycle. By proposing the model of wei qi circulating from yin to yang， this study offers novel insights on the understanding of postprandial drowsiness.

Objective:To explore the role of serum cholinesterase (CHE) levels in the prognosis of patients with acute decompensated heart failure (ADHF).Methods:Total of 244 consecutive patients with ADHF who were admitted to the emergency department and were successfully discharged were prospectively enrolled from January 2018 to June 2020. Patients were divided into groups according to the first and third quartile of CHE level and the clinical data, laboratory tests and other nutritional indices were recorded after discharge, and then were followed up. The primary end points were the composites of cardiovascular death and hospitalization for worsening HF (composite end points). The secondary end points were all-cause mortality and cardiovascular death. Cox proportional risk analysis, time-dependent Cox regression model or stratified cox regression were used to identify the risk of primary and secondary endpoints. Clinical, biomarker and the compound models of clinical and biomarker were constructed. Kaplan-Meier method was used to plot the survival curves of different groups and compare their differences. Receiver Operating characteristics (ROC) curves were used to compare the area under the curve for CHE levels and other nutritional or prognostic indicators to identify composite end-point events.Results:During a follow-up period of 350(100,683) days, 158 patients reached the composite end points. In the multivariable Cox analysis, cholinesterase level was significantly associated with the composite end points after adjustment for major confounders. Cox proportional risk analysis or time-dependent Cox regression model showed that CHE level was significantly associated with the composite end points, all-cause mortality and cardiovascular mortality in both clinical, biomarker and composite models (all P< 0.05). A Kaplan–Meier analysis revealed that patients with low cholinesterase levels had significantly greater risk of reaching the composite end points than those with middle or high cholinesterase levels (78.1% vs 66.7% vs. 46.7%, P<0.001); Cholinesterase level showed the largest area under the receiver operating characteristic curve (AUROC) of 0.736 (95% CI, 0.664-0.888) for prediction of the composite end points among other nutritional indices. The AUROC of the Global Meta-Analysis Group Chronic Heart Failure (MAGGIC) Risk Score for prediction of the composite end points was increased from 0.704 to 0.762 ( P=0.038), when cholinesterase level was added. Conclusions:Cholinesterase may serve as a simple and effective prognostic marker for predicting adverse outcomes in ADHF patients.

Objective:To study the clinicopathological features of Sjogren′s syndrome (SS) with liver injury and to improve the understanding of this disease.Methods:Forty-nine patients with SS complicated with liver injury were collected from Beijing Ditan Hospital, Capital Medical University from October 2008 to January 2022. All patients underwent ultrasound-guided liver biopsy, and all specimens were stained with HE. The histopathologic characteristics were observed and the pathologic indexes were graded. Immunohistochemical stains for CK7, CK19, CD38, MUM1 and CD10 were performed by EnVision method; and special histochemical stains for reticulin, Masson′s trichrome, Rhodanine, Prussian blue, periodic acid Schiff (PAS) and D-PAS stains were conducted .Results:The age of patients ranged from 31 to 66 years, including 3 males and 46 females. SS combined with drug-induced liver injury was the most common (22 cases, 44.9%), followed by autoimmune liver disease (13 cases, 26.5%, including primary biliary cholangitis in eight cases, autoimmune hepatitis in 3 cases, and PBC-AIH overlap syndrome in 2 cases), non-alcoholic fatty liver disease (NAFLD, 9 cases, 18.4%) and other lesions (5 cases, 10.2%; including 3 cases of nonspecific liver inflammation, 1 case of liver amyloidosis, and 1 case of porto-sinusoidal vascular disease). Among them, 28 cases (57.1%) were associated with obvious interlobular bile duct injury, mainly in SS combined with PBC group and drug-induced liver injury group. Twenty-three cases (46.9%) were associated with hepatocyte steatosis of varying degrees. In SS with autoimmune liver disease group, ISHAK score, degree of fibrosis bile duct injury, bile duct remodeling, lymphocyte infiltration of portal area, and plasma cell infiltration, MUM1 and CD38 expression; serum ALP and GGT, IgM; elevated globulin; positive AMA, proportion of AMA-M2 positive and IgM positive were all significantly higher than those in other groups(all P<0.05). Serum ALT, direct bilirubin and SSA positive ratio in SS combined with drug liver group were significantly higher than those in other groups(all P<0.05). The serum total cholesterol level in SS combined with PBC group ( P=0.006) and NALFD group ( P=0.011) were significantly higher than those in other groups ( P<0.05). Conclusions:The pathologic manifestations of SS patients with liver injury are varied. The inflammatory lesions of SS patients with autoimmune liver disease are the most serious, and the inflammatory lesions of SS patients with non-alcoholic fatty liver disease and non-specific inflammation are mild. Comprehensive analysis of liver histopathologic changes and laboratory findings is helpful for the diagnosis of SS complicated with different types of liver injury.

Objective:To investigate the clinicopathological characteristics of rashes in monkeypox patients through a series of skin biopsies, and examine their pathological features and the most effective tests.Methods:Patients with monkeypox virus infection admitted to Beijing Ditan Hospital from June to August 2023 were identified. Among them, 24 patients underwent skin biopsies for clinical pathological study that were included in this study. Clinical information, rash pictures, and nucleic acid test results were analyzed using histopathology, immunohistochemistry, RNAscope ? hybridization and electron microscopy. Results:All 24 patients were male, including 14 patients with concurrent human immunodeficiency virus infection. Their average age was (32.3±5.4) years. The nucleic acid test confirmed monkeypox virus infection. The clinical feature of monkeypox rashes was solitary rather than clustered distribution, with rashes occurring in similar phase, distinguishing it from herpesvirus. The rashes in these patients were mostly scattered, with an average of (13.0±11.8) rashes, and most commonly present in the perineum, face, limbs, and trunk. The three main pathological features of these rashes were ballooning degeneration of the epidermal spinous cell layer, the characteristic intra-cytoplasmic Guarnieri′s bodies and significant infiltration of inflammatory cells in whole dermal layer. Immunohistochemistry, RNAscope ? hybridization, and electron microscopy can all effectively detect the monkeypox virus. Electron microscopy showed viral replication in various types of skin cells. Conclusions:The study describes the pathological features of monkeypox virus rashes. Pathological examination of skin biopsy samples is helpful to diagnose these rashes. The study suggests that the monkeypox virus has a unique epitheliotropic affinity and can infect various types of cells in the skin.

Objective:To explore the value in differentiating Borrmann Ⅳ type gastric cancer (BT4-GC) from gastric diffuse large B-cell lymphoma (DLBCL) using a nomogram based on CT texture analysis (CTTA) and morphological characteristics.Methods:From June 2011 to December 2020, a total of 60 patients with BT4-GC and 24 patients with DLBCL were retrospectively collected in Nanjing Drum Tower Hospital Clinical College of Nanjing Medical University. Morphological characteristics were evaluated, including major location, long axis range, circumferential range, mucosal line status, and perigastric enlarged lymph nodes. CTTA parameters were calculated using venous CT images with a manual region of interest. The morphological characteristics and CTTA parameters between BT4-GC and DLBCL were compared by χ 2 test, Fisher exact test or Mann-Whitney U test. The multivariate binary logistic regression analysis was used to filter factors into the diagnostic model and construct a nomogram. The receiver operating characteristic (ROC) curve was used to evaluate the diagnostic performance of CTTA parameters and the diagnostic model in differentiating BT4-GC from DLBCL. Results:For morphological characteristics, mucosal line status showed a significant difference between BT4-GC and DLBCL (χ 2=12.99, P<0.001). For CTTA parameters, 16 parameters showed significant differences between BT4-GC and DLBCL (all P<0.05). The area under the ROC curve (AUC) of 16 CTTA parameters in differentiating BT4-GC from DLBCL was 0.662-0.833. Percentile 90 showed the highest AUC of 0.833 (95%CI 0.736-0.906). The mucosal line status (OR 4.82, 95%CI 1.21-19.25, P=0.026) and percentile 90 (OR 1.09, 95%CI 1.04-1.15, P=0.001) were brought into the diagnostic model and constructed a nomogram. The AUC of the model in differentiating BT4-GC from DLBCL was 0.898 (95%CI 0.813-0.953), sensitivity was 0.833, and specificity was 0.817. Conclusions:The nomogram based on CTTA percentile 90 and morphological characteristics mucosal line status can effectively distinguish BT4-GC from DLBCL and shows high diagnostic efficacy.
