Obesity and its related metabolic diseases have become a major global public health threat, and its rising incidence significantly increases the risk of cardiovascular and cerebrovascular diseases, diabetes and other complications. Pancreatic lipase is a key enzyme that converts food-borne lipids into triglycerides and fatty acids, and the effective inhibition of its activity has become an important strategy for the treatment of obesity. This paper discusses the screening methods of pancreatic lipase inhibitors, and summarizes and reviews the basic principles, advantages and disadvantages and application status of traditional screening methods, modern new screening methods and virtual screening methods. In view of the problems faced by the screening methods of pancreatic lipase inhibitors, future research urgently needs to move towards a collaborative innovation path of multi-technology integration, intelligent screening and complex systematization of traditional Chinese medicine, so as to open up new research paradigms.

Fecal microbiota transplantation （FMT） has been widely used in the treatment of gastrointestinal disorders， particularly Clostridium difficile infection， while there are few reports of its application in the diagnosis and treatment of cirrhotic ascites. This article reports a case of a patient with cirrhotic ascites and chronic diarrhea who received FMT with oral capsules， demonstrating significant short-term efficacy without any adverse reactions， in order to provide a reference for the application of FMT in the treatment of liver diseases.

ObjectiveTo explore the mechanism of modified Xiehuangsan in treating tic disorders （TD） based on microglial polarization and the Toll-like receptor 4 （TLR4）/myeloid differentiation factor 88 （MyD88）/nuclear factor （NF）-κB pathway. MethodsSeventy-two Sprague-Dawley （SD） rats were randomly assigned into six groups： control， model， tiapride （0.025 g·kg^-1）， and low-， medium-， and high-dose （12， 24， 48 g·kg^-1， respectively） modified Xiehuangsan， with 12 rats in each group. Except the control group， the other groups received intraperitoneal injection of 3，3'-iminodipropionitrile （IDPN） for 7 consecutive days for the modeling of TD. After successful modeling， the control and model groups were given normal saline via gavage， and the other groups were administrated with corresponding drugs by gavage. After 28 days of continuous intervention， rat behaviors were observed， and the modified Xiehuangsan group showing the best anti-TD effect was selected for deciphering the treatment mechanism. Hematoxylin and eosin staining was conducted to observe morphological changes in the rat striatum. Immunohistochemistry was employed to detect the expression of CD16 and CD206 in the striatum. Real-time PCR was employed to measure the mRNA levels of interleukin-1β （IL-1β）， tumor necrosis factor-α （TNF-α）， IL-4， TLR4， MyD88， and NF-κB p65 in the striatum. Western blot was employed to determine the protein levels of ionized calcium-binding adapter molecule 1 （Iba1）， Fc receptor family for immunoglobulin （Ig）G type Ⅲ （CD16）， mannose receptor （CD206）， TLR4， MyD88， and NF-κB p65 in the striatum. ResultsCompared with the control group， the model group showed increased stereotyped behaviors， locomotor activity， total movement distance， and movement speed， shortened resting time （P<0.01）， and noticeable pathological changes in the striatum. Compared with the model group， the tiapride group and modified Xiehuangsan groups exhibited reduced stereotyped behavior， locomotor activity， total movement distance， and movement speed， prolonged resting time （P<0.05， P<0.01）， and alleviated pathological changes in the striatum. Among the modified Xiehuangsan groups， the high-dose group had the best intervention effect and the mildest pathological changes. Therefore， the high-dose group was selected for further research. Compared with the control group， the modeling of TD increased Iba1 and CD16 expression （P<0.05， P<0.01）， up-regulated the mRNA levels of IL-1β and TNF-α （P<0.05， P<0.01）， down-regulated the mRNA level of IL-4 （P<0.05）， up-regulated the mRNA and protein levels of TLR4 and MyD88 （P<0.05， P<0.01）， and up-regulated the protein level of NF-κB p65 （P<0.01）. Compared with the model group， modified Xiehuangsan reduced Iba1 and CD16 expression （P<0.05， P<0.01）， up-regulated the protein level of CD206 （P<0.05， P<0.01）， down-regulated the mRNA levels of IL-1β and TNF-α （P<0.05）， up-regulated the mRNA level of IL-4 （P<0.01）， and down-regulated the mRNA and protein levels of TLR4， MyD88， and NF-κB p65 （P<0.05， P<0.01）. ConclusionModified Xiehuangsan demonstrated a definite therapeutic effect on TD in rats. It may reduce neuroinflammation in TD rats by regulating the polarization of microglia in the striatum via the TLR4/MyD88/NF-κB signaling pathway.

Abstract The global prevalence of non-suicidal self-harm (NSSI) among adolescents is becoming increasingly severe. Traditional mental health services are struggling to meet the growing social demand due to limited resource allocation and service accessibility. The rapid development of artificial intelligence (AI) technology provides a new technological path. The article systematically reviews the research progress of AI technology in adolescent NSSI, demonstrating key technologies such as machine learning, natural language processing, and deep learning in predicting NSSI risk prediction, emotion recognition and online intervention for adolescents. However, challenges remain, including algorithm bias, data privacy protection, model interpretability and ethical decision making. Future research should focus on multi disciplinary collaborative cooperation based on artificial intelligence to build a safe, effective and sustainable digital psychological intervention system, so as to provide innovative strategies and technical support for the early warning and intervention of NSSI behavior in adolescents.

Vitrification cryopreservation technology converts the liquid water in biological samples into glassy solids through ultra-rapid cooling. In this review, the core research of vitrification cryopreservation technology was mainly reviewed, such as the optimization of cryoprotectant formulations, the improvements to temperature control methods, the innovative carrier designs and the improvements to rewarming technology. The application status and issues in the fields of organ preservation, tumor research, reproductive medicine and rare cell preservation were also summarized. By combining the technical principles with glassy state detection methods, a theoretical basis was provided for optimizing the technical system and expanding application scenarios, thereby promoting its large-scale application in clinical and biological sample libraries.

Gastric cancer （GC） has an insidious onset and is mostly diagnosed in the middle and late stages after clinical detection. It is one of the malignant tumors with high incidence and mortality rates in the world. At present， the treatment plans are optimized mainly in terms of surgery， radiotherapy， and intervention， while the endpoints of clinical trials， such as patients' overall survival， progression-free survival， and disease-free survival， are still unsatisfactory. Therefore， effectively delaying the dynamic inflammation-cancer transformation has become an urgent bottleneck in the prevention and treatment of GC. In 1920s， Professor Otto Warburg discovered the phenomenon that tumor cells can accelerate glycolysis. Since then， the abnormal metabolic network inside tumor cells has gradually entered into researchers' view， and the hot academic research topic of metabolic reprogramming has been proposed. Tumor cells can meet their own energy consumption and adapt to external changes by adjusting their metabolic pathways to achieve rapid proliferation. In recent years， traditional Chinese medicine （TCM） is resolutely pursuing innovation in inheritance and the continuous refinement of research has led to the precision-oriented transition of TCM theories. Therefore， linking TCM with the treatment of tumors and precancerous diseases has certain research connotations. The searching and review of the publications in this field revealed that the number of publications in tumor-related metabolism increased dramatically， while there were only a few studies using TCM as a therapeutic solution. The research group has long been committed to the study of precancerous lesions of gastric cancer （PLGC） in Chinese and Western medicine. This article explained the dynamic process of inflammation-cancer transformation from the perspective of spleen deficiency-Qi stagnation-collateral stasis. The molecules of hypoxia-inducible factor （HIF）-1α， cancer-Myc （c-Myc）， apolipoprotein E （APOE） and pyruvate kinase M2 （PKM2） were selected to reflect the biological connotation of inflammation-cancer transformation. The current achievements of TCM in regulating the metabolic reprogramming to intervene in inflammation-cancer transformation were summarized， with a view to providing more information for TCM to intervene in the inflammation-cancer transformation of gastric mucosa.

Objective To investigate the correlation between levels of intercellular adhesion molecule-1 (ICAM-1), platelet surface P-selectin (CD62P), and inflammatory factors and cerebral artery stenosis in patients with acute cerebral infarction (ACI). Methods A total of 305 patients with ACI complicated with cerebral artery stenosis admitted to Zhongwu Hospital of Suqian City and Xinyi People's Hospital from January 2021 to December 2023 were selected as the research subjects. According to the degree of cerebral artery stenosis, they were divided into grade I group (stenosis degree<50%, n=85), grade II group (stenosis degree of 50%-75%, n=128), and grade III group (stenosis degree>75%, n=92). Sixty-eight ACI patients without cerebral artery stenosis during the same period were included in the reference group. The levels of serum inflammatory factors [C-reactive protein (CRP), tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), and interleukin-8 (IL-8)], ICAM-1 and CD62P were compared among the four groups. Spearman analysis was used to analyze the correlation between each factor and degree of cerebral artery stenosis. Results The levels of CRP, TNF-α, IL-6, IL-8, ICAM-1 and CD62P in the grade I, II and III groups were higher than those in the reference group. The levels of these factors were higher in the grade II and III groups than those in the grade I group, while the levels of various factors were higher in the grade III group than those in the grade II group (P<0.05). Spearman analysis showed that CRP, TNF-α, IL-6, IL-8, ICAM-1, and CD62P were positively correlated with the degree of cerebral artery stenosis in patients with ACI complicated with cerebral artery stenosis (P<0.05). Conclusion The levels of serum inflammatory factors, ICAM-1 and CD62P are significantly correlated with cerebral artery stenosis degree in patients with ACI.
