ObjectiveAge-related macular degeneration （AMD） is one of the leading causes of low vision and blindness in people over 50 years old， and dry AMD （dAMD） is one type for which there is currently no clear treatment. On the basis of the diagnosis and clinical characteristics of dAMD in traditional Chinese and Western medicine， this paper evaluated the fitting degrees of existing animal models of dAMD with clinical characteristics according to the evaluation methods of animal models， and put forward suggestions and prospects. MethodsLiterature on animal models of dAMD was searched against database， and the characteristics of the models were assigned according to the diagnosis criteria of diseases and syndromes of traditional Chinese and Western medicine， and the fitting degrees of the models with clinical characteristics were analyzed and evaluated. ResultsAt present， the animal models of dAMD are mainly established targeting complement factors， chemokines， oxidative damage， lipid/glucose metabolism， and natural strains. Most of the models can simulate the major pathological changes of dAMD， showing the fitting degree of 25%-50% with clinical characteristics in Western medicine. However， the evaluation of traditional Chinese medicine （TCM） syndromes， especially the evaluation of secondary syndromes， is missing， and the models present low fitting degrees with the clinical characteristics in TCM. ConclusionExisting animal models of dAMD are mostly established under the guidance of Western diagnostic standards， which reproduce the main disease characteristics of Western medicine and lack observation of TCM syndromes. Future studies can pay attention to the intervention factors and evaluation systems of spleen deficiency Qi deficiency and liver-kidney Yin deficiency syndrome and build the animal model of dAMD with integration of disease and syndrome based on clinical characteristics of traditional Chinese and Western medicine.

ObjectiveTo explore the possible mechanism of the Yiqi Jiedu formula （YQ） in treating ischemic stroke （IS） from the perspective of the microbial-gut-brain axis （MGBA）. MethodRats were randomly divided into five groups， with six in each group， including sham surgery group， model group， and low， medium， and high dose YQ groups （1， 5， and 25 mg·kg^-1）. Except for the sham surgery group， all other groups were established with a middle cerebral artery occlusion （MCAO） model using the thread occlusion method. The success of modeling was determined through neurobehavioral scoring， and the protective effect of YQ on IS was evaluated. Then， the changes in gut microbiota before and after MCAO modeling and YQ administration were compared using 16S rDNA sequencing technology， and the possible biological pathways related to the effect of this formula were analyzed. The expression of inflammatory factors such as interleukin-6 （IL-6）， interleukin-17A （IL-17A）， and interleukin-10 （IL-10） in serum was detected by enzyme-linked immunosorbent assay （ELISA）. Western blot was used to detect the expression of tight junction proteins ZO-1 and Occludin in brain and intestinal tissue， and hematoxylin-eosin staining （HE） was used to observe pathological changes in the cerebral cortex and colon， so as to validate the possible mechanism of action. ResultYQ significantly improved the neurobehavioral score of MCAO rats （P<0.01） and played a good regulatory role in intestinal microbial disorders caused by enriched pathogens and opportunistic pathogens during the acute phase. Among them， significantly changed microorganisms include Morgentia， Escherichia Shigella， Adlercreutzia， and Androbacter. Bioinformatics analysis found that these bacteria may be related to the regulation of inflammation in the brain. Compared with the blank group， the detection of inflammatory factors in the serum of IS model rats showed an increase in inflammatory factors IL-6 and IL-17A （P<0.01） and a decrease in the content of anti-inflammatory factor IL-10 （P<0.01）. Compared with the model group， the content of inflammatory factors IL-6 and IL-17A in the serum of the treatment group decreased （P<0.05）， and that of anti-inflammatory factor IL-10 increased （P<0.01）. The expression results of barrier proteins ZO-1 and Occludin in brain and intestinal tissue showed that the expression levels of both decreased in IS model rats （P<0.05）， while the expression levels of both increased in the treatment group （P<0.05）. ConclusionAcute cerebral ischemia can lead to an imbalance of intestinal microbiota and damage to the intestinal barrier， and it can increase intestinal permeability. YQ can regulate intestinal microbiota imbalance caused by ischemia， inhibit systemic inflammatory response， and improve the disruption of the gut-blood brain barrier， preventing secondary cascade damage to brain tissue caused by inflammation. The MGBA may be an important mechanism against the IS.

Objective To investigate whether BPA and its substitutes BPAF,BPB,and BPS can induce lipid accumulation in hepato-cytes.Methods HL-7702 cells were treated with BPA,BPAF,BPB,or BPS for 24 h.Lipid droplet accumulation in cells was observed via oil red O staining,and triglyceride content was determined through the GPO-PAP chemical-enzymatic method.In addition,qRT-PCR was used to detect the expression of triglyceride synthesis-related genes.Results Red lipid droplets of different sizes could be observed in the BPA,BPAF,BPB,and BPS groups.The intracellular triglyceride content increased significantly under 1 and 50 μmol/L BPA,10 and 50μmol/L BPAF,1,10,and 50μmol/L BPB,and 50μmol/L BPS.LIPIN2 mRNA expression level increased significantly under 10μmol/L BPAF,10μmol/L BPB,and 1 and 10μmol/L BPS.DGAT2 mRNA expression increased significantly under 50μmol/L BPA,10μmol/L BPAF,10 and 50μmol/L BPB,and 1μmol/L BPS.Conclusion BPAF,BPB,and BPS can increase intracellular triglyceride synthesis by upregulating LIPIN2 and DGAT2 mRNA expression,leading to intracellular fat accumulation and increased triglyceride con-tent in HL-7702 cells.

ObjectiveTo investigate the monitoring status and epidemiological characteristics of foodborne disease pathogens in Baoshan District， Shanghai so as to improve early detection and warning capabilities of foodborne diseases outbreaks， and to provide a scientific basis for the prevention and control of foodborne diseases. MethodsAnal swabs or fecal samples from food-borne diarrhea cases were collected from two sentinel surveillance medical institutions in Baoshan District of Shanghai during 2019 and 2021. Salmonella， diarrheagenic Escherichia coli， Shigella， Vibrio parahaemolyticus， campylobacter and norovirus were tested in anal swabs and fecal samples， and all the testing results were statistically analyzed. ResultsA total of 1 693 cases were reported， among which 1 693 anal swabs and fecal samples were collected， with a male-to-female ratio of 1.04∶1. The largest number of cases was from the age group of 45-64 years （504 cases）. The highest number of reported cases was among retirees （762 cases）. The high-incidence period of the diseases was in summer and autumn， with the highest number of cases associated with meat and meat products （566 cases）. The primary location of exposure was at home （1 260 cases）. The detection rate of pathogenic bacteria and virus was 21.32%， among which campylobacter accounted for the largest proportion （10.28%）. The peak incidence rate was from May to September. The detection rate of norovirus was 13.29%， with a higher incidence in winter and spring. The predominant serotype of Salmonella was Salmonella enteritidis （41.82%）， and the predominant local serotype of diarrheagenic Escherichia coli was EAEC （50.52%）. Campylobacter was mainly represented by jejuni （81.61%）， and the predominant type of norovirus was GⅡ （60.87%）. ConclusionCampylobacter has the highest proportion among foodborne pathogens causing foodborne diseases in Baoshan District， followed by diarrheogenic Escherichia coli. And norovirus GⅡ type is the predominant virus. Appropriate prevention and control measures should be taken based on the characteristics of each pathogen's epidemiology.

Objective:To investigate the characteristics and influencing factors of esophageal stenosis after endoscopic submucosal dissection (ESD) for early esophageal carcinoma.Methods:Patients who underwent ESD in the Digestive Endoscopy Center of the Second Affiliated Hospital of Army Medical University from January 2011 to December 2018 were included. The data were obtained from medical records and follow-up. The influencing factors of stenosis were determined by single factor and Cox regression analysis.Results:A total of 654 patients underwent ESD and 79 (12.1%) of them developed postoperative esophageal stenosis. The median time of stenosis development was 27 (17, 43) days. The morphology and lesion circumferential proportion were independent factors for the occurrence of stenosis after ESD. The stenosis incidence of type Ⅱa was 6.601 times (95% CI: 1.518-28.709, P=0.012) compared with that of type Ⅱc. The incidence of stenosis in lesions with 75%-<100% and 100% circumference was 17.408 times (95% CI: 8.009-37.839, P<0.001)and 52.439 times (95% CI: 23.905-115.029, P<0.001) respectively compared with that of patients <75%. Among the 79 patients, 27 had severe stenosis, and the lesion circumferential proportion was an independent factor for stenosis. Compared with the group of lesion circumferential proportion of less than 75%, the incidences of stenosis of lesion circumferential proportion of 75%-<100% and 100% were 7.775 (95% CI: 1.977-30.577, P=0.003) and 70.062 (95% CI: 19.879-246.926, P<0.001) times respectively. Conclusion:The morphology and lesion circumferential proportion are two independent factors for the occurrence of esophageal stenosis after ESD. Additionally, lesion circumferential proportion is an independent factor for the occurrence of severe esophageal stenosis after ESD.
