Objective To establish an individualized nomogram model and evaluate its efficacy to provide a possible evaluation basis for the prognosis of lower third and abdominal part of oesophageal adenocarcinoma (EAC). Methods Lower third and abdominal part of EAC patients from 2010 to 2015 were chosen from the SEER Research Plus Database (17 Regs, 2022nov sub). The patients were randomly allocated to the training cohort and the internal validation cohort with a ratio of 7∶3 using bootstrap resampling. The Cox proportional hazards regression analysis was used to determine significant contributors to overall survival (OS) in EAC patients, which would be elected to construct the nomogram prediction model. C-index, calibration curve and receiver operating characteristic (ROC) curve were performed to evaluate its efficacy. Finally, the efficacy to evaluate the OS of EAC patients was compared between the nomogram prediction model and TNM staging system. Results In total, 3945 patients with lower third and abdominal part of EAC were enrolled, including 3475 males and 470 females with a median age of 65 (57-72) years. The 2761 patients were allocated to the training cohort and the remaining 1184 patients to the internal validation cohort. In the training and the internal validation cohorts, the C-index of the nomogram model was 0.705 and 0.713, respectively. Meanwhile, the calibration curve also suggested that the nomogram model had a strong capability of predicting 1-, 3-, and 5-year OS rates of EAC patients. The nomogram also had a higher efficacy than the TNM staging system in predicting 1-, 3-, and 5-year OS rates of EAC patients. Conclusion This nomogram prediction model has a high efficiency for predicting OS in the patients with lower third and abdominal part of EAC, which is higher than that of the current TNM staging system.

As people’s attention to health continues to increase, the market demand for traditional Chinese medicine (TCM) is growing steadily. The quality and safety of Chinese medicinal materials have attracted unprecedented social attention. In particular, the issue of exogenous harmful residue pollution in TCM has become a hot topic of concern for both regulatory authorities and society. The Chinese Pharmacopoeia 2025 Edition further refines the detection methods and limit standards for exogenous harmful residues in TCM. This not only reflects China’s high-level emphasis on the quality and safety of TCM but also demonstrates the continuous progress made by China in the field of TCM safety supervision. Basis on this study, by systematically reviewing the development history of the detection standards for exogenous harmful residues in TCM and analyzing the revisions and updates of these detection standards in the Chinese Pharmacopoeia 2025 Edition, deeply explores the key points of the changes in the monitoring standards for exogenous harmful residues in TCM in the Chinese Pharmacopoeia 2025 Edition. Moreover, it interprets the future development directions of the detection of exogenous residues in TCM, aiming to provide a reference for the formulation of TCM safety supervision policies.

Objective To assess the tear film stability and morphological characteristics of the tarsal gland in myopic children.Methods In this prospective descriptive study,myopic children who performed refractive examinations in the Pediatric Ophthalmology & Refraction Clinic,Jinan Mingshui Eye Hospital from November 2021 to November 2022 were in-cluded.An Ocular Surface Disease Index(OSDI)questionnaire survey was carried out;tear meniscus height(TMH),non-invasive first breakup time(NIf-BUT)and images of the tarsal glands were obtained by OCULUS Keratograph 5M compre-hensive ocular surface analyzer.In addition,the atrophy and tortuosity of tarsal glands were scored to analyze the tear film stability and clinical characteristics of tarsal glands in myopic children.Results A total of 48 myopic children(91 eyes)aged from 7 to 16(10.25±2.23)years were recruited,including 27 males(56.25％)and 21 females(43.75％).The aver-age TMH was(0.19±0.04)mm(95％CI:0.18-0.19)and the average NIf-BUT was(5.40±2.62)s(95％CI:4.90-5.94);the TMH was positively correlated with NIf-BUT(r=0.223,P=0.034).The tarsal gland atrophy score was 1(0,1).The tortuosity score of the upper and lower tarsal gland was 0(0,1)and 0(0,0),respectively,with a statistically significant difference(Z=3.692,P＜0.001).In all subjects,49 eyes(53.85％)had tarsal gland atrophy,and 37 eyes(40.66％)had tarsal gland tortuosity.There were significant differences in TMH and NIf-BUT between children aged＜12 years and children aged ≥12 years(both P＜0.05).There was a significant difference in TMH between children with an OSDI score＜13 and children with an OSDI score ≥ 13(t=2.305,P=0.026).There was a significant difference in NIf-BUT between mild and moderate myopia children(t=2.300,P=0.024);the spherical equivalent was positively correlated with NIf-BUT(r=0.283,P=0.023).Conclusion Children with mild to moderate myopia show low tear film stability and a certain proportion of abnormal morphology in tarsal glands.In addition to the refractive status of children,attention should also be paid to ocular surface health in the refraction clinic.

Objective:To compare the effects of different test meals on postprandial triglycerides and to optimize the standard meal composition and the blood sampling protocol for the oral fat tolerance test.Methods:This study is a prospective, open-label, randomized, cross-over trial. In March 2023, 36 volunteers were recruited in Hebei General Hospital. They underwent a health examination and oral glucose tolerance test. Twenty-six healthy volunteers(11 males and 15 females) were included in this study, with an average age of(39.08±4.56) years. Each volunteer received 75 g protein meal, 75 g fat meal, 700 kcal fixed-calorie high-fat mixed meal, and a high-fat mixed meal with energy adjusted based on 10 kcal/kg body weight. A one-week washout period of regular diet was applied before each trial. Blood was collected at fasting status and 1, 2, 3, 4, 5, and 6 hours after a meal to detect serum triglycerides, total cholesterol, low density lipoprotein-cholesterol(LDL-C), high density lipoprotein-cholesterol(HDL-C), glucose, and insulin. The variations of postprandial metabolic indicators over time following the consumption of different test meals were analyzed. The disparities in postprandial metabolic responses between the two types of mixed meals were compared.Results:The protein meal, fat meal, fixed-calorie high-fat mixed meal, and adjusted-calorie high-fat mixed meal resulted in postprandial triglyceride increases of 22.45%, 115.40%, 77.14%, and 63.63%, and insulin increase of 560.43%, 85.69%, 554.18%, and 598.97%, respectively, and with reductions in total cholesterol, LDL-C, and HDL-C ranging from 5.64%-21.81%, respectively. The blood glucose changed slightly. Changes in metabolic indicators mainly occured within 4 hours. The comparison of the characteristics of postprandial triglycerides between the two high-fat mixed meals showed no statistically significant differences( P>0.05). Conclusion:A standardize protocol with a 700 kcal fixed-calorie high-fat mixed meal as test meal, and blood lipid levels measured at fasting and at 1, 2, 3, and 4 hours after consumption, can serve as an optimized approach for oral fat tolerance test.

Objective: To understand the nutritional literacy level and associated factors of primary and secondary school students in Beijing, so as to provide a scientific basis for improving student nutrition. Methods: From October 2022 to May 2023, a multi stage cluster random sampling method was employed to select a total of 14 568 primary, junior and senior high school students from 16 districts (ecluding the Economic Technological Development area) in Beijing. Through a survey questionnaire on nutritional literacy and dietary hehavior of school age children, basic information as well as data on nutritional literacy levels across four dimensions:nutrition related knowledge concepts, food selection, food preparation, and food intake dimensions were obtained. The Wilcoxon rank sum test, Kruskal-Wallis test, Spearman correlation analysis, Chi square test and binary Logistic regression were used for the analysis. Results: The median total score of nutritional literacy among primary and secondary school students in Beijing was 68.8. Approximately 26.0% of primary and secondary school students achieved nutritional literacy standards. The median scores and rates of meeting the standards for nutrition related knowledge concepts, food selection, food preparation and food intake dimensions were 23.0, 42.1%; 17.0, 27.4%; 6.5, 33.5%; 23.0, 33.3%, respectively. There were positive correlations between all pairs of the four dimensions ( r=0.33-0.49, P <0.05). The results of multiple Logistic regression analysis showed that primary school students, junior high school students, female students, suburban students, caregivers with a college education level and a bachelor s degree or above were the positive arrelation factors that promoted the achievement of nutritional literacy standards ( OR =2.21, 1.39, 1.18, 1.27, 1.42, 1.66, P <0.05). Conclusion The literacy level of primary and secondary school students in Beijing needs to be significantly improved. School stage, gender, region and caregiver s education level are associated factors.

kidney deficiency and blood stasis are believed to be the key pathogenesis of recurrent implantation failure （RIF）， and therefore， it is proposed to take kidney-supplementing and blood-invigorating as the basic treatment method， and use it by stages to assist the controlled superovulation program of in vitro fertilization-embryo transfer （IVF-ET）. The focus should be put on nourishing kidney yin， soothing the liver and invigorating blood during down-regulation period， using kidney yin-nourishing medicinals and modified Qinghao Biejia Decoction （青蒿鳖甲汤）. During the ovulation induction period， the focus should be put on nourishing kidney yang， replenishing blood， and promoting blood circulation， with self-made Bushen Culuan Formula （补肾促卵方） in modifications. After transplantation， it is suggested to put focus on tonifying the kidneys and replenishing essence， and self-made Wuzi Yanzong Guchong Decoction （五子衍宗固冲汤） in modifications can be used. At the same time， fetal protection treatment should be carried out for pregnant women， and modified Shou Tai Pill （寿胎丸） can be used to tonify the kidneys and calm the fetus.

Objective This study aimed to observe the effect of Jiang Tang San Hao Formula(JTSHF)on systemic and intestinal inflammation,as well as on the NLRP3 inflammasome in type 2 diabetic mice(T2DM),and to elucidate its anti-diabetic molecular mechanisms.Methods Four-week-old male C57BL/6 N mice were used to establish the T2DM model using a high-fat diet combined with streptozotocin injection.The diabetic mice were randomly divided into the model,metformin,and JTSHF groups.A control group was also set to provide baseline comparisons.Each group of mice was orally administered with the corresponding medication daily.The metformin group was orally administered with 0.20 g/kg metformin,the JTSHF group was orally administered with 4.26 g/kg JTSHF,and the control group and model group were orally administered with an equal amount of sterile water continuously for 8 weeks.After an 8-week drug intervention via gavage,the lipopolysaccharide(LPS),tumor necrosis factor-alpha(TNF-α),interleukin 1 beta(IL-1β),and interleukin 6(IL-6)serum and colon levels were quantified using an enzyme-linked immunosorbent assay(ELISA).The pathological morphology of the colon was observed using hematoxylin and eosin staining.NOD-like receptor protein 3(NLRP3),apoptosis-associated speck-like protein containing a caspase recruitment domain(ASC),caspase-1,zonula occludens-1(ZO-1),occludin,and G-protein coupled receptor 43(GPR43)protein expression in the colon were assessed using immunohistochemistry.The mRNA expression levels of NLRP3,ASC,caspase-1,ZO-1,Occludin,and GPR43 in the colon were detected using Real-time PCR.Results The ELISA data revealed significant differences in inflammatory markers among the groups.Compared with the model group,the JTSHF group exhibited notably reduced LPS,TNF-α,IL-1β,and IL-6 levels(P<0.05).Moreover,compared with the model group,JTSHF treatment upregulated ZO-1,occludin,and GPR43 protein and mRNA expression in the colon and downregulated NLRP3,ASC,and Caspase-1 protein and mRNA expression(P<0.05).Conclusion The inflammatory reaction of T2DM mice is apparent.JTSHF effectively alleviates the systemic and intestinal inflammatory response of T2DM mice by inhibiting the NLRP3 inflammasome and repairing the intestinal mucosal barrier,highlighting the potential molecular mechanisms of the anti-diabetes effects of JTSHF.
