ObjectiveTo elucidate the potential mechanisms by which the classic prescription Anmeidan alleviates cognitive impairment in insomnia model rats through metabolic profiling. MethodsA total of 60 SD rats were randomly divided into six groups： blank group， model group， low-， medium-， and high-dose Anmeidan groups， and the Suvorexant group， with 10 rats in each group. Except for the blank group， the insomnia model was established in all other groups via intraperitoneal injection of para-chlorophenylalanine. The Suvorexant group was administered Suvorexant solution （30 mg·kg^-1·d^-1） by gavage， while the low-， medium-， and high-dose Anmeidan groups received Anmeidan decoction （4.55， 9.09， 18.18 g·kg^-1·d^-1） by gavage. The blank group received an equivalent volume of normal saline. The open field test was used to assess spatial exploration and anxiety/depressive-like behaviors in rats. Serum levels of epidermal growth factor （EGF）， brain-derived neurotrophic factor （BDNF）， and vasoactive intestinal peptide （VIP） were measured using enzyme-linked immunosorbent assay （ELISA）. Untargeted metabolomics was employed to identify differential metabolites in rat serum， and systematic biological methods were applied to analyze the potential targets and pathways of Anmeidan. ResultsCompared to the blank group， the model group exhibited significant reductions in total distance traveled， average speed， number of entries into the central area， time spent in the central area， and frequency of upright events （P<0.01）， along with significant decreases in VIP， EGF， and BDNF levels （P<0.05，P<0.01）. A total of 100 differential metabolites were identified between the model and blank groups. Compared to the model group， the low-， medium-， and high-dose Anmeidan groups showed significant increases in total distance traveled， average speed， number of entries into the central area， time spent in the central area， and frequency of upright events （P<0.05，P<0.01）， as well as a significant increase in VIP levels （P<0.05，P<0.01）. Anmeidan significantly reversed abnormal changes in 67 metabolites compared to the model group. A combined analysis identified 134 potential targets of Anmeidan， with network topology analysis suggesting that Caspase-3， B-cell lymphoma 2 （Bcl-2）， nuclear transcription factor-κB （NF-κB）， interleukin-1β （IL-1β）， interleukin-2 （IL-2）， matrix metalloproteinase-9 （MMP-9）， and Toll-like receptor 4 （TLR4）， among others， may serve as key targets of Anmeidan. Kyoto Encyclopedia of Genes and Genomes （KEGG） pathway analysis revealed major enriched pathways， including the cyclic adenosine monophosphate （cAMP） signaling pathway， hypoxia inducible factor-1 （HIF-1） signaling pathway， and IL-17 signaling pathway. ConclusionThis study demonstrates that Anmeidan can recalibrate abnormal metabolic profiles in insomnia model rats to mitigate cognitive impairment， with its mechanisms of action potentially involving the regulation of immune-inflammatory responses， energy metabolism， and apoptosis-related pathways.

AIM: To investigate the relationship between Apelin and δ-like ligand 4(DLL4)expression levels and clinical stage and efficacy in patients with neovascular glaucoma(NVG).METHODS: A total of 96 NVG patients(96 eyes)who were admitted to our hospital from January 2022 to March 2024(NVG group)and 96 cataract patients(96 eyes)who underwent cataract surgery in our hospital during the same period(control group)were selected. NVG patients were divided into stage Ⅰ group(22 eyes), stage Ⅱ group(47 eyes)and stage Ⅲ group(27 eyes)according to the clinical stage; furthermore, patients were divided into ineffective group(20 eyes)and effective group(76 eyes)according to efficacy. Aqueous humor Apelin and DLL4 levels were detected by enzyme-linked immunosorbent assay. The influencing factors of the efficacy in NVG patients were analyzed by multivariate unconditional Logistic regression analysis, the evaluation efficiency of aqueous humor Apelin and DLL4 levels on the efficacy in NVG patients was analyzed by receiver operating characteristic(ROC)curve.RESULTS: Compared with the control group, aqueous humor Apelin and DLL4 levels in the NVG group were increased(all P<0.001). Aqueous humor Apelin and DLL4 levels in the stage Ⅰ, stage Ⅱ and stage Ⅲ groups increased in turn(all P<0.001). The effective rate of 96 NVG patients was 79.2%(76/96). Compared with the effective group, aqueous humor Apelin and DLL4 levels in the ineffective group increased(all P<0.001). Clinical stage III, high intraocular pressure, high Apelin and DLL4 were independent risk factors for ineffective treatment in NVG patients(all P<0.05). The area under the curve of the combined evaluation of aqueous humor Apelin and DLL4 levels in evaluating the efficacy of NVG patients was 0.874, which was greater than 0.790 and 0.786 of aqueous Apelin and DLL4 levels alone(all P<0.05).CONCLUSION: Aqueous humor Apelin and DLL4 levels in NVG patients increase, which relate to the increase of clinical stage and poor efficacy, and the combination of aqueous humor Apelin and DLL4 levels is more effective in evaluating the efficacy of NVG patients.

Objective To predict the lymph node metastasis status of patients with invasive pulmonary adenocarcinoma by constructing machine learning models based on primary tumor radiomics, peritumoral radiomics, and habitat radiomics, and to evaluate the predictive performance and generalization ability of different imaging features. Methods A retrospective analysis was performed on the clinical data of 1 263 patients with invasive pulmonary adenocarcinoma who underwent surgery at the Department of Thoracic Surgery, Jiangsu Province Hospital, from 2016 to 2019. Habitat regions were delineated by applying K-means clustering (average cluster number of 2) to the grayscale values of CT images. The peritumoral region was defined as a uniformly expanded area of 3 mm around the primary tumor. The primary tumor region was automatically segmented using V-net combined with manual correction and annotation. Subsequently, radiomics features were extracted based on these regions, and stacked machine learning models were constructed. Model performance was evaluated on the training, testing, and internal validation sets using the area under the receiver operating characteristic curve (AUC), F1 score, recall, and precision. Results After excluding patients who did not meet the screening criteria, a total of 651 patients were included. The training set consisted of 468 patients (181 males, 287 females) with an average age of (58.39±11.23) years, ranging from 29 to 78 years, the testing set included 140 patients (56 males, 84 females) with an average age of (58.81±10.70) years, ranging from 34 to 82 years, and the internal validation set comprised 43 patients (14 males, 29 females) with an average age of (60.16±10.68) years, ranging from 29 to 78 years. Although the habitat radiomics model did not show the optimal performance in the training set, it exhibited superior performance in the internal validation set, with an AUC of 0.952 [95%CI (0.87, 1.00)], an F1 score of 84.62%, and a precision-recall AUC of 0.892, outperforming the models based on the primary tumor and peritumoral regions. Conclusion The model constructed based on habitat radiomics demonstrated superior performance in the internal validation set, suggesting its potential for better generalization ability and clinical application in predicting lymph node metastasis status in pulmonary adenocarcinoma.

Objective:To explore the correlation between clinical classification and genotype and prognosis among Chinese children with Very-long chain acyl-CoA dehydrogenase deficiency (VLCADD).Methods:A Chinese pedigree affected with VLCADD admitted at the First People′s Hospital of Yunnan Province in February 2019 was selected as the study subject. The characteristics of disease onset, diagnosis and treatment and prognosis were retrospectively analyzed. Relevant literature was also systematically searched and reviewed.Results:The proband, a 1-year-old boy, had the clinical manifestations of frequently vomiting, hypoglycemia, abnormal liver function and myocardial enzymes. Tandem mass spectrometry screening showed significantly elevated C14, C14: 1, C16: 1, C16: 2, C18 and C14/C8. Genetic testing revealed that he has harbored compound heterozygous variants of the ACADVL gene, namely c. 664G>A (p.G222R) and c. 1345G>A (p.E449K), which were respectively derived from his father and mother. The child was diagnosed with VLCADD cardiomyopathy type and deceased 2 weeks later. Literature review has identified 60 Chinese children with VLCADD. The clinical classifications were mainly cardiomyopathy type and liver disease type, which accounted for 73.3% (43/60). The combination of ACADVL gene variants were correlated with the clinical classifications of VLCAD. Children with one or two loss-of-function (LOF) mutations showed more severe clinical manifestation and a higher mortality. Cardiomyopathy type had the poorest prognosis, with a mortality rate of 76.9% (20/26). C14: 1 may be used as an indicator for the diagnosis of VLCADD, but cannot be used for clinical subtyping and prognosis evaluation. The c. 1349G>A (p.R450H) variant had the highest frequency among the Chinese patients, accounting for 10.8% (13/120). Conclusion:The clinical classifications of VLCADD are strongly correlated with the prognosis, and LOF mutations are more common in those with severe clinical manifestations. c. 1349G>A (p.R450H) may be the most common variant among the Chinese patients, and early screening and diagnosis can greatly improve the prognosis of patients.

Objective To investigate the epidemiological characteristics and changing trend of malignant tumor death in Danjiangkou City, the water source area along the middle route of South-to-North Water Diversion Project. Methods The surveillance data of cancer death cases in Danjiangkou City from 2015 to 2022 were collected, and the mortality rate, gender mortality rate, age-specific mortality rate and the rank of cancer cause of death were calculated. Joinpoint regression model was used to analyze the trend of malignant tumor mortality and standardized mortality. Annual percentage change (APC) and average annual percentage change (AAPC) were calculated to analyze the trend changes. Results From 2015 to 2022, a total of 6 254 deaths from malignant tumors were reported in Danjiangkou City, with a crude mortality rate of 178.57/100 000 and a standardized mortality rate of 152.77/100 000. There were 4 366 male deaths, and the crude mortality and standardized mortality were 244.70/100 000 and 212.87/100 000 , respectively. There were 1 888 female deaths, and the crude mortality rate and the standardized mortality rate were 109.89/100 000 and 92.69/100 000, respectively. The crude death rate of malignant tumors in the whole population in Danjiangkou City showed an increasing trend from 2015 to 2022, and the difference was statistically significant (AAPC=5.18%, t=4.07, P<0.05). The crude mortality rates of malignant tumors in both men and women showed an upward trend, and the differences were statistically significant (AAPC =5.56% and 4.35%, both P<0.05). The standardized mortality rates of malignant tumors in the whole population, women and men remained stable, and the differences were not statistically significant (AAPC=0.68, 1.59 and -0.74, all P>0.05). The trend analysis of age-specific mortality of malignant tumors showed that the age-specific mortality of malignant tumors in the whole population, men and women showed an increasing trend with age, and the differences were statistically significant (AAPC =9.22%, 9.40% and 8.53%, P<0.05). The mortality rate of malignant tumors in 0-, 1-, 10-, 45- and 70- age groups decreased year by year (AAPC =-79.62%, -7.19%, -65.99%, -8.88%, and -5.83%, all P<0.05). The mortality rate in the age group of over 75 years old showed an increasing trend (AAPC =12.24%, P<0.05), and the differences were statistically significant. The top 10 malignant tumor deaths in the whole population were lung cancer, gastric cancer, liver cancer, esophageal cancer, colorectal cancer , leukemia , pancreatic cancer , breast cancer , brain malignant tumor and cervical cancer, accounting for 88.49% of all malignant tumor deaths. Mortality rates in lung cancer (AAPC =6.75%), esophageal cancer (AAPC=11.24%), colorectal cancer (AAPC =12.95%), leukemia (AAPC=8.10%), pancreatic cancer (AAPC=15.11%), breast cancer (AAPC=13.11%) and brain malignancies (AAPC=11.16%) showed an increasing trend, and the differences were statistical significant (P<0.05). Conclusion Malignant tumor is the main cause of death in Danjiangkou City. The death rate increases year by year and increases with age. Lung cancer, stomach cancer and liver cancer are the main causes of death. Men and the elderly are high-risk groups of malignant tumors. Early detection and treatment of malignant tumors should be strengthened to reduce the incidence and death.

OBJECTIVE To estimate the quality markers of antioxidant activity for standard decoction of Schisandrae Chinensis Fructus.METHODS 15 batches of Schisandrae Chinensis Fructus standard decoctions were subjected to quality evaluation by ultra high-performance liquid chromatography(UPLC)based on single-marker(QAMS)method,before being summarized by chemometrics analysis.The antioxidant abilities of 15 batches of samples were determined by DPPH and ABTS methods,while gray correlation analy-sis(GRA)and the partial least squares regression(PLSR)methods were subsequently applied to investigating the relationship between the contents of 8 components and the antioxidant activity.Ultimately,molecule docking was utilized to explore the binding properties between candidate quality markers and the core targets of anti-oxidation,with the experimental verification being executed on the indi-vidual compound by in vitro anti-oxidation.RESULTS There was no remarkable difference between the results of QAMS and external standard method(ESM),with P valued greater than 0.05.And it was speculated that protocatechuic acid,gomisin A,schizantherin B and schisandrin B were the constituents of quality difference.Moreover,the 4 quality variation components were reckoned to be the al-ternative markers on antioxidant according to the results of GRA and PLSR.The molecule docking result also showed that 4 candidate quality markers presented good binding affinity with the antioxidant core targets.The antioxidant capacity was presumably originated from the collaborated effects by multi-components in the standard decoction of Schisandrae Chinensis Fructus.In the interim,protocate-chuic acid exhibited noteworthy antioxidant efficacy with dosage-depended manner in the results of single-compound verification,which was best conformed to the characteristics of quality markers and supposed to be the antioxidant quality marker for Schisandrae Chinensis Fructus standard decoction.CONCLUSION This research predicts the potential antioxidant substances on the basis of content deter-mination by UPLC and in vitro antioxidant assay,but also provides rational foundation for quality assessment on other preparations of Schisandrae Chinensis Fructus.
