Objective: Attention-deficit/hyperactivity disorder (ADHD) is one of the most common neurodevelopmental disorders in children and adolescents, often accompanied by motor function disorders. Sarcopenia not only has skeletal muscle dysfunction but also has neurocognitive dysfunction. At present, there is no research to explore the relationship between ADHD and skeletal muscle function. The purpose of this study is to explore whether there is a causal effect between ADHD and sarcopenia. Methods: In this study, genome-wide association study data of ADHD, appendicular lean mass (ALM), hand grip strength, and walking pace (WP) were extracted from public databases. The bidirectional two-sample Mendelian randomization (MR) method was employed to investigate the correlation between ADHD and sarcopenia-related indicators, and the inverse-variance weighted analysis as the primary analysis method. Results: Based on the forward MR analysis, a potential causal relationship exists between ADHD and ALM (odds ratio [OR]=1.020, 95% confidence interval [CI]: 1.012–1.029, p<0.001). The reverse MR analysis indicates a link between WP and the risk of ADHD (OR=2.712, 95% CI: 1.609–4.571, p<0.001), with an accelerated WP increasing the likelihood of ADHD. Nevertheless, other MR analysis results did not show significant differences. Conclusion The findings of this study indicate an intricate causal relationship between ADHD and sarcopenia, suggesting the absence of a clear link. WP may be used as one of the indicators to evaluate the risk of ADHD. At the same time, we should pay more attention to the ALM of ADHD patients.

Objective:To explore the prevalence, clinical features, genetic characteristics and prognosis of Citrin deficiency in Henan province of China.Methods:A total of 986 565 neonates screened by tandem mass spectrometry at the Third Affiliated Hospital of Zhengzhou University from January 2013 to December 2021 were retrospectively analyzed. Analysis of SLC25A13 gene variants and parental verification were carried out for neonates suspected for Citrin deficiency by next-generation sequencing. The clinical, biochemical and genetic characteristics of Citrin deficiency patients were integrated to guide the diet treatment and follow up the growth and development. Paired- t test was used to compare the amino acid levels in the peripheral blood samples before and after the treatment. Results:Nine cases of Citrin deficiency were diagnosed among the 986 565 neonates. Specific elevation of citrulline was observed in all of the 9 cases. Six variants were detected by genetic sequencing, among which c. 852_855delTATG, c. 615+ 5G>A, c. 550C>T and IVS16ins3kb were known pathogenic variants, whilst c. 1111_1112delAT and c. 837T>A were unreported previously. The detection rate for c. 852_855delTATG was the highest (61.6%, 11/18), followed by IVS16ins3kb (16.7%, 3/18). The clinical symptoms of all patients were relieved after the treatment, and the blood amino acid profile and biochemical parameters were significantly improved by gradually falling within the normal range. By June 2022, all patients had shown a good prognosis.Conclusion:The prevalence of Citrin deficiency among neonates from Henan Province by tandem mass spectrometry is 1/109 618, and the carrier rate for the pathogenic variants of the SLC25A13 gene was 1/166. The c. 852_855delTATG may be a hot spot variant among the patients. Discovery of the novel variants has enriched the mutational spectrum of the SLC25A13 gene. Above results have provided a basis for the early diagnosis, treatment, prognosis and genetic counseling for the affected families.

Purpose To investigate the clinical value of multi-center digital mammography radiomics nomogram model in predicting triple-negative breast cancer(TNBC).Materials and Methods The digital mammograms of 462 patients with pathologically confirmed breast cancer from November 2016 to March 2022 were retrospectively analyzed,including 243 cases from Yijishan Hospital of Wannan Medical College(institution 1),106 cases from Fuyang People's Hospital(institution 2)and 113 cases from Taihe People's Hospital(institution 3).According to the results of immunohistochemistry,a total of 349 breast cancer patients in institution 1 and institution 2 were randomly divided into the training group(244 cases,including 41 TNBC and 203 non-TNBC)and the validation group(105 cases,including 18 TNBC and 87 non-TNBC)according to the ratio of 7∶3,113 breast cancer patients(24 TNBC and 89 non-TNBC)from institution 3 were included in the external validation group.Comparing the mediolateral oblique and cranial cauda digital mammography images,the mammography imaging with larger lesion areas were selected,and the image segmentation and radiomics feature extraction were performed.The radiomics model was constructed by using Logistic regression.The clinicopathological parameters and radiomics scores were used to construct a nomogram.Receiver operating characteristic and decision curve analysis were used to evaluate the model performance.To compare The predictive performance between the models was compared.Results Finally,four radiomics features closely related to TNBC were selected to construct an radiomics model.The area under the curve,sensitivity and specificity of TNBC predicted by the radiomics model in training group,validation group and external test group were 0.868,90.24%and 72.91%,0.827,72.22%and 75.86%,0.837,70.83%and 78.65%,respectively.The area under the curve,sensitivity and specificity of TNBC predicted by the combined model in the training group,validation group and external test group were 0.903,80.49%and 86.70%,0.890,77.78%and 88.51%,0.870,62.50%and 85.39%,respectively.The combined model was better than the single image omics model in predicting TNBC,and the difference was statistically significant between the training group and the verification group(Z=2.061,2.064,both P<0.05),but not between the external test group(Z=1.223,P=0.221).In three group,decision curve analysis showed that the nomogram predicted a higher net benefit than the radiomics model for triple-negative breast cancer.Conclusion The radiomics model has high diagnostic efficiency in predicting TNBC,and the nomogram model combined with the radiomics score and histological grading can further improve the prediction efficiency.

Objective:The Qinzhi Zhudan formula(QZZD)exhibits a prominent therapeutic effect in the treatment of vascular dementia(VaD).This study combined a network pharmacology approach and experimental validation to identify the underlying biological mechanism of QZZD against VaD.Methods:Male Wistar rats received bilateral common carotid artery occlusion(BCCAO)surgery,and after 4 weeks of intragastric administration of QZZD,the therapeutic effect was assessed using the Morris water maze test and cerebral blood flow(CBF)assessment.Hematoxylin and eosin staining,Nissl staining,and electron microscopy were used to measure the histopathological changes in the neurons of rats.The effect of QZZD treatment on hippocampal neurotransmitters was assessed by high-performance liquid chromatography with electrochemical detection and liquid chromatography mass spectrometry.Immunofluorescence was used to observe VaD-induced microglia activation.The inflammatory cytokine levels were assessed by enzyme linked immunosorbent assay.Western blot was used to examine the TNFR1-mediated TNF pathway,which was screened out by network pharmacology analysis.Results:QZZD treatment alleviated pathological changes and neuronal damage in VaD rats and atten-uated their cognitive impairment.In addition,QZZD increased CBF and the expression of acetylcholine and 5-hydroxytryptamine in the hippocampal region.Notably,QZZD inhibited microglial activation and the expression of IL-6 and TNF-a.Network pharmacology and western blot indicated that QZZD inhibited the levels of TNFR1,NF-KBp65,p-ERK,TNF-α,and IL-6,which are related to the TNFR1-mediated TNF signaling pathway.Conclusion:QZZD clearly improved learning and memory function,reduced brain pathological damage,elevated CBF and hippocampal neurotransmitter levels,and alleviated neuroinflammation of VaD rats partly by inhibiting the TNFR1-mediated TNF pathway,indicating its potential value in the clinical therapy of VaD.
