Background::The prevalence of type 2 diabetes mellitus (T2DM) has been rapidly growing in Chinese populations in recent decades, and the shift in eating habits is a key contributing factor to this increase. Eating out of home (EOH) is one of the major shifts in eating habits during this period. However, the influence of EOH on the incidence of T2DM among Chinese urban workers is unknown.Methods::The cross-sectional study involved an analysis of 13,904 urban workers recruited from 11 health examination centers in the major cities of China to explore the relationship between EOH and T2DM between 2013 September and 2016 March.Results::Average weekly EOH frequency ≥10 times was positively associated with increased incidence of T2DM in the sampled population (OR: 1.31 [1.11-1.54], p < 0.01), most notably in participants ≤45 years old (OR: 1.41[1.11-1.80], p < 0.01]) and in males (OR:1.26 [1.06-1.51], p < 0.01). An EOH frequency of 5 times/week appears as a threshold for a significant increase in the odds of T2DM. Weekly EOH frequency ≥5 times was associated with increased odds of T2DM in a dose-response manner in the total population and almost all subgroups ( poverall association < 0.05 and pnonlinearity ≤ 0.05). Conclusion::This study showed that a frequency of EOH (≥5 times/week) was associated with a frequency-dependent increase in the odds of T2DM urban workers in China. More nutrition promotion is needed to improve the eating behavior of Chinese urban workers to reduce T2DM risk.

Gastric ulcer(GU)is one of the common,frequently-occurring and intractable diseases of the digestive system.Spleen-stomach deficiency cold type is the most common and hard-to-cure syndrome pattern of GU,and is both a focus and a challenge in medical research.Therefore,constructing a scientific,reasonable,and clinically practical animal model of GU with spleen-stomach deficiency cold type and formulating objective and effective evaluation criteria are of great significance for in-depth research on the pathogenesis and treatment of GU.In this paper,the methods for constructing GU animal models of spleen-stomach deficiency cold type are comprehensively introduced by systematically reviewing the relevant literature.Firstly,the construction methods of pathological models of GU in Western medicine are introduced,including pyloric ligation method,water immersion-restraint stress method,ethanol-induced method,acetic acid-induced method,etc.This paper expounds the establishment methods for spleen-stomach deficiency cold syndrome type model in traditional Chinese medicine(TCM),including diet disorder method,bitter cold diarrhea method,excessive fatigue method,Qi consumption and Qi impairment method,and overeating sour-flavor method.This paper focuses on the construction methods for disease-syndrome combination GU models of spleen-stomach deficiency cold type,including two-factor modeling method and three-factor modeling method.Meanwhile,the evaluation indices of GU animal models of spleen-stomach deficiency cold type were summarized from various aspects,including animal physical signs(appearance symptoms,animal behavior,and metabolic indices),as well as tissue morphology and molecular biology-related indicators(gastric function,oxidative stress,inflammatory factors,other cytokines,four coagulation parameters,intestinal flora detection),for constructing a comprehensive evaluation system.From the perspective of prescription-based verification,this paper further analyzes the drug composition and pharmacological effects to infer the syndrome type of the treated animal model,so as to verify whether the target animal model is successfully constructed.This review aims to provide a valuable reference for establishing a syndrome-specific GU animal model that closely aligns with clinical reality and embodies the principles of Chinese medicine.This will further advance research on TCM-pattern GU syndromes and deepen the exploration of herbal medicine-based treatments for GU,ultimately promoting the clinical integration and advancement of Chinese medicine in GU therapy.

OBJECTIVE To compare anti-ischemic stroke （IS） effect of different extraction parts from Gastrodia elata， and to provide reference for screening the anti-IS effective parts of G. elata. METHODS G. elata was extracted and separated by ethanol reflux extraction and ethyl acetate extraction. The rat model of diffuse cerebral thrombosis was induced by internal carotid artery injection of arachidonic acid （AA）； the anti-IS effect of G. elata powder， ethanol extract of G. elata， residue of ethanol extract of G. elata， ethyl acetate extract of G. elata， residue of ethyl acetate extract of G. elata， gastrodin and aspirin （positive control drug） were investigated with the content of Evans blue （EB） in the ischemic brain tissue as index. RESULTS Compared with model group， aspirin， ethanol extract of G. elata and ethyl acetate extract of G. elata could significantly decrease the content of EB in the ischemic brain tissue of model rats （P＜0.05）. G. elata powder had the tendency to reduce the content of EB in the ischemic brain tissue of model rats， without statistical significance （P＞0.05）. The residue of ethanol extract of G. elata， residue of ethyl acetate extract of G. elata and gastrodin had little effect on the content of EB in the ischemic brain tissue of model rats. CONCLUSIONS Both ethanol extract of G. elata and ethyl acetate extract of G. elata have anti-IS effects， which are stronger than that of G. elata powder.

Objective:To understand the needs of online medical community users for stroke disease information, and lay the foundation for providing medical care services that meet the needs of stroke patients.Methods:Data mining was used to examine the question records related to stroke in 3 Chinese online medical communities. The data from August 1, 2020 to July 31, 2021 were collected through the crawler code, and the themes were mined using the Latent Dirichlet Allocation (LDA) model after data cleaning and word segmentation.Results:The subject feature analysis of the online medical community question records showed that the LDA model divided 33 731 question records into 4 aspects and 8 themes of information needs, namely, symptom identification and emergency treatment (symptoms, sudden symptoms and emergency measures) , medical diagnosis and treatment (examination and treatment, medical diagnosis, surgery) , rehabilitation care (daily care, diet and medication) , and patients and caregivers' needs for psychological care knowledge (patients or caregivers' concerns about disease prognosis) .Conclusions:The research results based on LDA model can reflect the information needs of online medical community users with stroke, and provide the development direction and information support for meeting the information needs of stroke specialist care and providing structured health education.

OBJECTIVE：To obs erve the protective effect of protoca techuic aldehyde（PAL）on neurovascular unit （NVU） homeostasis damage in rats after cerebral ischemia-reperfusion injury （CIRI）. METHODS ：SD rats were randomly divided into sham operation group ，model group ，PAL high-dose and low-dose groups （10，20 mg/kg），with 11 rats in each group. Administration groups were given relevant medicine intragastrically. Sham operation group and model group were given the same volume of normal saline intragastrically ，10 mL/kg once a day ，for 5 days. After last administration ，CIRI model was induced by suture method ；the ultrastructural changes of NVU were observed by transmission electron microscope. Western blot assay was used to detect the expression of NUV related proteins （MAP-2，GFAP，AQP-4）in cerebral tissue. Immunofluorescence staining was used to observe the positive expression of above proteins in cerebral cortex. RESULTS ：Compared with sham operation group ， blood-brain barrier （BBB）structure of model group was destroyed severely ，the vascular lumen became narrower ，lateral edema of endothelial cells was severe ，and the thickness of basement membrane varied ；the nuclei of neurons were pyknosis and there was a large area of edema in the surrounding tissues ；the structure of glial cells was seriously damaged ，the cell body was shrunk and organelles were lost ；protein expression （or positive expression ）of MAP- 2 in brain tissue （or cerebral cortex ）were significantly decreased （P＜0.05 or P＜0.01），while protein expression （or positive expression ） of GFAP and AQP- 4 were increased significantly（P＜0.01）. After PAL intervention ，the rats had less BBB damage ，and the morphology of vascular lumen and basement membrane were not completely destroyed ；the damage of neurons was alleviated ，the pyknosis of neurons was decreased ， the chromatin was homogeneous and the heterochromatin was decreased；the damage of glial cell structure was alleviated protein expression of GFAP and AQP- 4（except for low-dose group） in cerebral tissue and positive expression of MAP- 2 and GFAP protein in cerebral cortex were reversed @qq.com significantly （P＜0.05 or P＜0.01）. CONCLUSIONS ：PAL can protect the stability of NVU from damage in CIRI model rats； the mechanism may be related to up-regulating the expression of MAP- 2 protein in cerebral cortex and down-regulating the expression of GFAP and AQP- 4 protein in brain tissue.

The imbalance of lipid metabolism is an important factor causing a series of metabolic diseases such as non-alcoholic fatty liver disease (NAFLD) and hyperlipidemia.Liver X receptors is a member of the nuclear receptor superfamily, which maintains cholesterol homeostasis by regulating cholesterol absorption, transport, reverse cholesterol transport, biosynthesis and other functions.It plays an important role in maintaining lipid homeostasis by regulating de novo fat synthesis to maintain the balance of fatty acids in the body.

Objective To evaluate the effects of extractive from Gastrodiae Rhizoma on acquisition, consolidation and retrieval of learning-memory function in mice;To provide some reference for clinical research and development of new drugs.Methods Male Kunming mice were randomly divided into control group, model group, positive control group and Gastrodia extractive group. Positive control group and Gastrodia extractive group were given gavage by using relevant medicine 0.2 mL/10 g, and the control group and model group were given gavage with the same amount of distilled water for 16 days. After receiving gavage for continuous 11 days, memory acquisition barrier model was induced by scopolamine;memory consolidation barrier model was induced by chloromycetin;memory retrieval barrier model was induced by EtOH. The learning-memory function was reviewed by escape latency and spatial search distance. The quadrant and distance search time percentage was detected through directional navigation test and spatial probe test in Morris water maze.Results Extractive from Gastrodia Rhizoma shortened the time for acquisition, consolidation and retrieval of learning memory about escape latency and spatial search distance (P<0.05,P<0.01), and the quadrant and distance search time percentage were prolonged (P<0.01).Conclusion Extractive from Gastrodia Rhizoa can effectively improve the acquisition, consolidation and retrieval of learning-memory function in mice.
