ObjectiveTo explore the pathological mechanism-syndrome-treatment patterns of approved Chinese patent medicines （CPMs） that treat collateral disorders， providing a reference for the principle of "treating different diseases with the same therapy" in collateral pathology. MethodsCPMs that apply treatment strategies based on collateral disorders were identified from the Pharmacodia database by extracting information from the "efficacy" or "indications" sections of drug package inserts. A database was established to extract the names and compositions of the CPMs， as well as their indications， related traditional Chinese medicine （TCM） symptoms， disease locations （affected areas）， and pathological factors. Frequency statistics were performed. Using the Apriori algorithm， an association rule analysis was conducted on CPMs and disease-location combinations related to the top three most frequent pathological factor combinations. Core formulas for these combinations were identified and analyzed through drug network analysis and MCODE module clustering. ResultsA total of 660 CPMs targeting collateral disorders were retrieved， involving 299 indications， 323 TCM symptoms， 21 disease locations， 19 pathological factors， and 124 pathological factor combinations. The most frequent pathological factor combinations were blood stasis （involved in 109 CPMs， 16.52%）， exogenous wind （外风） -cold-dampness （involved in 43 CPMs， 6.52%）， and qi deficiency-blood stasis （involved in 42 CPMs， 6.36%）. Analysis of the core formulas for these combinations revealed common ingredients such as Honghua （Carthami Flos）， Chuanxiong （Chuanxiong Rhizoma）， Danggui （Angelicae Sinensis Radix）， and Dilong （Pheretima）. ConclusionCollateral disorders involve a wide range of pathogenesis and represent a fundamental mechanism in the onset and development of various diseases， characterized by obstruction and stagnation. The primary therapeutic principle is unblocking of the collaterals. Blood stasis obstructing the collaterals is the core pathological basis， and the strategy of activating blood circulation and resolving stasis to unblock the collaterals should be central to the treatment. The core medication pattern involves combining blood-activating and stasis-resolving herbs with insect-derived medicinals that unblock collaterals. Exogenous wind is often the initiating patholo-gical factor in colla-teral disorders， and the appropriate addition of wind-dispelling herbs can enrich the treatment strategies for such conditions.

Objective To analyze cognition,attitude,behavior status and influencing factor of neurological nurses for early rehabilitation of stroke.Methods A tatol of 182 neurological nurses from 8 tertiary hospitals in Urumqi were selected as the research subjects to investigate the cognition,attitude from December 2022 to June 2023,and behavior status of neurology nurses for early rehabilitation of stroke and analyze their influencing factors.Results The scores of 182 neurological nurses during early rehabilitation of stroke were(72.57士6.79),the scoring rate was 72.57％,which was in the middle level.The average score of attitude was(89.62±2.94),and the scoring rate was 89.62％,which was at a high level.The average score of behavior was(62.08±21.50),and the scoring rate was 62.08％,which was in the middle level.Multivariate regression analysis showed that age was the influence factor of nurses'early rehabilitation cognition dimension and attitude dimension(P＜0.05);The influence factors of nurses'early rehabilitation behavior were their professional title and whether stroke had occurred among relatives and friends(P＜0.05).Conclusion Neurological nurses have a positive attitude towards early rehabilitation of stroke,but they do not implement nursing measures enough.It is suggested that rehabilitation nursing training courses should be set up to encourage nurses to update their knowledge and strengthen their self-learning so as to improve nursing behavior and improve nursing quality.

Objective To explore the clinicopathological and immunohistochemical features of nephrogenic adenoma(NA).Methods Clinical data of NA patients diagnosed in the Department of Pathology,Zhongshan Hospital,Fudan University from July 2016 to October 2022 were collected and analyzed to explore their clinicopathological features.Results A total of 13 NA cases were enrolled.There were 11 males and 2 females.Organs involved:ureter(n=7),bladder(n=5),bladder and ureter(n=1),renal pelvis(n=2).NA patients performed as ureteral stenosis(6/7),rough bladder wall(3/5),and renal pelvis polyp(2/2).The typical microscopical features of NA were tubular(13/13)and papillary(4/13)structures,covered with cuboidal or columnar epithelium(13/13),or a mixed hobnail-spike eosinophilic epithelium(12/13);the interstitium was loose,containing varied amounts of vasculature and inflammatory cells(13/13).Immunohistochemistry revealed specific expressions of CK7,PAX-8,CK19 and CK8.Conclusions NA is a rare neoplasm of the urinary system with unique histological features.NA has the risk of misdiagnosis and over-treatment,and the potential of recurrence and malignant conversion.The diagnosis of NA depends on pathology,and the immunohistochemistry can be helpful for its pathological diagnosis.

Both morbidity and mortality of gastric cancer are in the front rank among malignant tumors.At present,enhanced CT is served as an important imaging method for preoperative diagnosis and assessment of gastric cancer,but it is mostly based on morphological evaluation and unable to perform quantitative analysis.The functional imaging technology represented by energy spectral CT and CT perfusion imaging has a variety of quantitative parameters,which is expected to make up for the shortcomings of conventional CT.The review introduces the basic principles of energy spectral CT and CT perfusion imaging,and summarizes their applications in the diagnosis,pathological classification,grading,staging and efficacy prediction of gastric cancer,aiming to improve the understanding of functional CT imaging for the pretreatment assessment in gastric cancer.

Background/Aims: Metabolic dysfunction-associated steatohepatitis (MASH) is an unmet clinical challenge due to the rapid increased occurrence but lacking approved drugs. Autophagy-related protein 16-like 1 (ATG16L1) plays an important role in the process of autophagy, which is indispensable for proper biogenesis of the autophagosome, but its role in modulating macrophage-related inflammation and metabolism during MASH has not been documented. Here, we aimed to elucidate the role of ATG16L1 in the progression of MASH. Methods: Expression analysis was performed with liver samples from human and mice. MASH models were induced in myeloid-specific Atg16l1-deficient and myeloid-specific Atg16l1-overexpressed mice by high-fat and high-cholesterol diet or methionine- and choline-deficient diet to explore the function and mechanism of macrophage ATG16L1 in MASH. Results: Macrophage-specific Atg16l1 knockout exacerbated MASH and inhibited energy expenditure, whereas macrophage-specific Atg16l1 transgenic overexpression attenuated MASH and promotes energy expenditure. Mechanistically, Atg16l1 knockout inhibited macrophage lipophagy, thereby suppressing macrophage β-oxidation and decreasing the production of 4-hydroxynonenal, which further inhibited stimulator of interferon genes(STING) carbonylation. STING palmitoylation was enhanced, STING trafficking from the endoplasmic reticulum to the Golgi was promoted, and downstream STING signaling was activated, promoting proinflammatory and profibrotic cytokines secretion, resulting in hepatic steatosis and hepatic stellate cells activation. Moreover, Atg16l1-deficiency enhanced macrophage phagosome ability but inhibited lysosome formation, engulfing mtDNA released by pyroptotic hepatocytes. Increased mtDNA promoted cGAS/STING signaling activation. Moreover, pharmacological promotion of ATG16L1 substantially blocked MASH progression. Conclusions ATG16L1 suppresses MASH progression by maintaining macrophage lipophagy, restraining liver inflammation, and may be a promising therapeutic target for MASH management.

Background/Aims: The accuracy of endosonographers in diagnosing gastric subepithelial lesions (SELs) using endoscopic ultrasonography (EUS) is influenced by experience and subjectivity. Artificial intelligence (AI) has achieved remarkable development in this field. This study aimed to develop an AI-based EUS diagnostic model for the diagnosis of SELs, and evaluated its efficacy with external validation. Methods: We developed the EUS-AI model with ResNeSt50 using EUS images from two hospitals to predict the histopathology of the gastric SELs originating from muscularis propria. The diagnostic performance of the model was also validated using EUS images obtained from four other hospitals. Results: A total of 2,057 images from 367 patients (375 SELs) were chosen to build the models, and 914 images from 106 patients (108 SELs) were chosen for external validation. The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of the model for differentiating gastrointestinal stromal tumors (GISTs) and non-GISTs in the external validation sets by images were 82.01%, 68.22%, 86.77%, 59.86%, and 78.12%, respectively. The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy in the external validation set by tumors were 83.75%, 71.43%, 89.33%, 60.61%, and 80.56%, respectively. The EUS-AI model showed better performance (especially specificity) than some endosonographers.The model helped improve the sensitivity, specificity, and accuracy of certain endosonographers. Conclusions We developed an EUS-AI model to classify gastric SELs originating from muscularis propria into GISTs and non-GISTs with good accuracy. The model may help improve the diagnostic performance of endosonographers. Further work is required to develop a multi-modal EUS-AI system.

Objective:To explore the correlation between choline,betaine,dimethylglycine,methionine and tri-methylamine oxide,metabolites related to the methionine cycle in carbon metabolism,and preeclampsia(PE)in di-chorionic diamniotic(DCDA)twin pregnancy.Methods:175 pregnant women with twin pregnancies who under-went regular prenatal examinations were registered in Peking University Third Hospital from July 2017 to April 2019 were included as the study subjects.According to whether PE had occurred,they were divided into non-PE group(138 cases)and PE group(37 cases).The fasting peripheral blood of pregnant women during the second trimester of pregnancy was collected,and the metabolites were quantitatively analyzed by ultra-high performance liquid chromatogrey-triple quadrupole tandem mass spectrometry(UHPLC-QqQ MS).The basic characteristics and plasma metabolite concentrations were compared between PE group and non-PE group.Poisson regression was used for plasma metabolite-related PE relative risk(RR)analysis,and receiver operating characteristic(ROC)curve was used to evaluate the accuracy of PE model prediction.Results:①Compared with the non-PE group,the rate of elderly pregnant women was higher,the concentration of betaine was lower,and the concentra-tion of choline was higher in PE group.The differences were statistically significant(P＜0.05).②Poisson regres-sion analysis showed that in the model adjusted for all confounding factors,there was a positive correlation be-tween maternal choline levels and PE risk(RR＞1,P＜0.05).The risk of PE occurrence increased as the in-crease of choline levels(Ptrend＜0.05).Betaine levels were negatively associated with PE risk(RR＜1,P＜0.05).The risk of PE occurrence decreased as the increase of betaine level(Ptrend＜0.05).There was no corre-lation between plasma levels of dimethylglycine,methionine and trimethylamine oxide and the risk of PE.③Pois-son regression analysis showed that the relative risk of PE was lowest when the plasma betaine/choline ratio was highest(RR0.32,95％Cl 0.14-0.75).When the dimethylglycine/betaine ratio was in the thirdpercentile,the risk of PE was increased in pregnant women(RR 2.53,95％Cl 1.01-6.32).(4)ln terms of PE prediction,the AUC combined with general risk factors and methionine metabolites was 0.80.Conclusions:Maternal choline and be-taine levels in the second trimester are related to the occurrence of PE in DCDA twin pregnancy,and provide a new idea for early prediction and intervention of PE.It is still necessary to expand the sample size to further verify and explore the mechanism.

Objective:To detect the expression levels of laboratory of genetics and physiology 2 (LGP2), retinoic acid inducible gene I (RIG-I) and melanoma differentiation associated gene 5 (MDA5) in children with hand, foot and mouth disease (HFMD), and to explore their possible clinical significance in HFMD.Methods:Fifty children with HFMD, who visited Second Affiliated Hospital of Xi′an Jiao Tong University, Xi ′an Children′s Hospital and Xi ′an Central Hospital from May 2020 to May 2021, were selected as the research subjects, and 20 children with physical examination at the same age during the same period were selected as the control group.Children with HFMD were divided into enterovirus 71 (EV-A71) type and coxsackievirus A6 (CV-A6) type according to the results of pathogen detection, and then divided into mild group and severe group according to the severity of the disease.The relative mRNA expression levels of LGP2, RIG-I and MDA5 in each group, and the correlation among the three proteins were compared and analyzed.Results:Among 50 cases of HFMD, 26 cases were EV-A71 type (16 cases were mild and 10 cases were severe) and 24 cases were CV-A6 type (17 cases were mild and 7 cases were severe). There was no significant difference in age and sex between HFMD group and control group ( P>0.05). The relative expression levels of LGP2 mRNA in EV-A71 and CV-A6 HFMD cases were 2.37(1.78, 3.25)% and 1.88 (1.35, 3.13)%, lower than that in control group [2.97(2.61, 3.55)%]. Only the difference between CV-A6 HFMD children and control group was statistically significant ( Z=-2.310, P=0.021). The relative expression levels of RIG-I mRNA in EV-A71 and CV-A6 HFMD cases were 9.95 (7.79, 14.62)% and 9.78(7.04, 15.83)%, lower than that in control group [18.47(13.00, 21.07)%]. The differences were all statistically significant ( P<0.05). The relative expression levels of MDA5 mRNA in EV-A71 and CV-A6 HFMD cases were 4.41(2.82, 5.99)% and 3.98 (2.18, 7.41)%, lower than that in control group [5.10(3.52, 7.71)%], but the differences were not statistically significant.There were no significant differences in the relative expression levels of the three indicators between the mild and severe groups of children with EV-A71 or CV-A6 HFMD.The expression levels of LGP2, RIG-I and MDA5 mRNA were highly correlated( P<0.001). Conclusion:The relative expression levels of LGP2, RIG-I and MDA5 mRNA in children with HFMD are decreased in different degrees than those in normal children.And there is a correlation among them.

Pulmonary blast injury has become the main type of trauma in modern warfare, characterized by externally mild injuries but internally severe injuries, rapid disease progression, and a high rate of early death. The injury is complicated in clinical practice, often with multiple and compound injuries. Currently, there is a lack of effective protective materials, accurate injury detection instrument and portable monitoring and transportation equipment, standardized clinical treatment guidelines in various medical centers, and evidence-based guidelines at home and abroad, resulting in a high mortality in clinlcal practice. Therefore, the Trauma Branch of Chinese Medical Association and the Editorial Committee of Chinese Journal of Trauma organized military and civilian experts in related fields such as thoracic surgery and traumatic surgery to jointly develop the Clinical treatment guideline for pulmonary blast injury ( version 2023) by combining evidence for effectiveness and clinical first-line treatment experience. This guideline provided 16 recommended opinions surrounding definition, characteristics, pre-hospital diagnosis and treatment, and in-hospital treatment of pulmonary blast injury, hoping to provide a basis for the clinical treatment in hospitals at different levels.
