ObjectiveTo explore the potential mechanism of different processed products of Baiyaojian and its compound Xiangmei pills in rats with ulcerative colitis（UC） by comparing the pharmacodynamic and metabolomic differences. MethodEighty SD rats were acclimatized and kept for 3 d， and randomly divided into 8 groups［blank group， model group， mesalazine group（0.4 g·kg^-1）， Baiyaojian group（1.89 g·kg^-1）， stir-fried Baiyaojian group（1.89 g·kg^-1）， carbonized Baiyaojian group（1.89 g·kg^-1）， and Xiangmei pills low and high dose groups（1.89， 5.67 g·kg^-1）］， with 10 rats in each group. Rats in the blank group were administered physiological saline by gavage， and rats in the remaining 7 groups were orally administered 5% dextran sodium sulfate（DSS） solution daily for 8 consecutive days to induce UC model. After successful modeling， each dosing group was given the corresponding dose of drug solution by gavage， and the blank and model groups were given equal amounts of saline by gavage， and the drug was administered continuously for 8 d. Then serum levels of tumor necrosis factor-α（TNF-α）， interleukin（IL）-6， IL-10 and IL-1β were measured by enzyme-linked immunosorbent assay（ELISA）， hematoxylin-eosin（HE） staining was used to observe the histopathological changes of colon tissue， the proportion of T helper 17 cells（Th17） and regulatory T cells（Treg） in the peripheral blood of rats in each group was detected by flow cytometry. The endogenous metabolites in serum of rats were detected by ultra performance liquid chromatography-quadrupole/electrostatic field orbitrap high-resolution mass spectrometry（UPLC-Q-Exactive Orbitrap MS）， and the differential metabolites were characterized by combining principal component analysis（PCA） and orthogonal partial least squares-discriminant analysis（OPLS-DA）， and were analyzed according to the variable importance in the projection（VIP） value>1.0 and P<0.05， and potential metabolic pathways were analyzed according to Human Metabolome Database（HMDB）. ResultCompared with the blank group， the colon tissue of the model group was congested and the mucosa was ulcerated， the colon length was significantly reduced（P<0.01） and the quality was significantly increased（P<0.05）， the proportion of Th17/Treg in the peripheral blood and the serum levels of TNF-α， IL-6 and IL-1β were significantly increased， while the IL-10 expression wassignificantly reduced（P<0.05， P<0.01）. Compared with the model group， the colon tissue of UC rats in each treatment group was improved with scattered ulcers， reduced inflammatory cell infiltration， significantly increased colon length， and significantly decreased mass（P<0.05）， the proportion of Th17/Treg in the peripheral blood decreased， the expression of TNF-α，IL-6 and IL-1β was significantly reduced（P<0.05， P<0.01）， while the IL-10 expression was significantly increased（P<0.01）. The therapeutic effect of different administration groups on UC was in the order of high dose group of Xiangmei pills>low dose group of Xiangmei pills>carbonized Baiyaojian group>stir-fried Baiyaojian group>Baiyaojian group. And a total of 26 differential metabolites were screened in the metabolomics results. Compared with the blank group， 14 differential metabolites were up-regulated and 5 metabolites were down-regulated in the model group， and 14， 9， 14， 12 and 17 metabolites could be recalled in the Baiyaojian group， stir-fried Baiyaojian group， carbonized Baiyaojian group， Xiangmei pills low and high dose groups. The main metabolic pathways involved were citrate cycle pathway， pantothenic acid and coenzyme A biosynthesis pathway， aromatic hydrocarbon receptor（AhR） signaling pathway， glycolysis/gluconeogenesis pathway. ConclusionThe therapeutic effect of Baiyaojian on UC is significantly improved after charcoal stir-frying， and the efficacy is more prominent when combined with Angelicae Dahuricae Radix and Mume Fructus Carbonisata， which can provide a basis for the development of Baiyaojian compound preparations.

Objective To explore the significance of milk fat globule-epidermal growth factor 8(MFGE8)and the polarization of macrophage M1/M2 in peripheral blood for assessing neurological deficits in patients with stroke.Methods A total of 120 patients diagnosed with stroke in the Second Central Hospital of Baoding from January 2021 to December 2022 who did not die during the follow-up period were selected as the study subjects.They were divided into two groups based on the outcomes of their neurological function recovery:a favorable prognosis group(68 patients)and an unfavorable prognosis group(52 patients).The differences of blood biochemical indices,the concentrations of MFGE8 in peripheral blood,and the M1 to M2 macrophage ratio were compared in both groups;The National Institutes of Health Stroke Scale(NIHSS)was used to evaluate the extent of neurological damage;Multivariate Logistic regression was used to analyze the influencing factors of neurological function recovery in stroke patients and the predictive value of patient prognosis;Spearman correlation analysis was used to explore the correlation between MFGE8 and the degree of neurological function impairment in patients.Results The levels of MFGE8 and proportion of M2 macrophages in the favorable prognosis group were significantly higher than those in the unfavorable prognosis group[MFGE8(ng/L):1 587.69±389.28 vs.1 008.78±456.89,proportion of M2 macrophages:(6.54±1.28)%vs.(3.21±0.89)%,both P<0.05],conversely,the proportion of M1 macrophages in the favorable prognosis group was significantly lower than that in the unfavorable prognosis group[(2.32±0.36)%vs.(6.54±1.28)%,P<0.05].Multiple Logistic regression analysis identified age,high-density lipoprotein cholesterol(HDL-C),low-density lipoprotein cholesterol(LDL-C),high-sensitivity C-reactive protein(hs-CRP),levels of MFGE8,length of hospital stay,NIHSS score,and the M1/M2 macrophage ratio as independent risk factors for neurological function recovery in stroke patients[odds ratio(OR)and 95%confidence interval(95%CI)were 1.23(1.05-1.44),0.78(0.64-0.95),2.44(1.40-4.21),1.95(1.12-3.38),0.24(0.10-0.58),1.25(1.04-1.48),1.45(1.07-1.94),1.23(1.05-1.44),Pvalues were 0.01,0.01,0.00,0.02,0.00,0.02,0.01,0.00 respectively].Spearman correlation analysis demonstrated a significant negative correlation between MFGE8 levels and neurological deficits(r=-0.32,P=0.00),whereas the M1/M2 macrophage ratio was significantly positively correlated with neurological deficits(r=0.41,P=0.00).Receiver operator characteristic curve(ROC curve)analysis indicated that the MFGE8 level could predict poor prognosis in stroke patients with area under the curve(AUC)=0.797,95%CI was 0.718-0.876,P=0.000;the optimal cut-off value being 1 123.8 ng/L with a sensitivity of 79.4%and specificity of 69.2%.Conclusion MFGE8 levels and the polarization of M1/M2 macrophages in peripheral blood are crucial for evaluating and influencing the recovery of neurological deficits in stroke patients.

Objective:To investigate the value of three-dimensional (3D) T 1WI structural images using different acceleration methods including parallel acquisition technique, joint compressed sensing (uCS) technique, and artificial intelligence-assisted compressed sensing (ACS) technique for brain region segmentation. Methods:In this cross-sectional study, fifty patients (female: n=25, age range: 13 to 87 years old) at Corning Hospital of Ningbo University from July to September 2023 were prospectively and consecutively collected. All the subjects underwent brain MRI. Six groups of 3D T 1WI structural images were obtained using different acceleration technique and parameters, including 3D T 1WI without acceleration factor (3D-T 1WI group), 3D T 1WI with parallel acquisition technique with acceleration factor 3 (3D-T 1WI-PI-3 group), 3D T 1WI with uCS technique with acceleration factor 4.5 and 6.9 (3D-T 1WI-uCS-4.5 group, 3D-T 1WI-uCS-6.9 group), 3D T 1WI by ACS technique with acceleration factors of 3 and 5 (3D-T 1WI-ACS-3 group, 3D-T 1WI-ACS-5 group). T 2WI fluid-attenuated inversion recovery (FLAIR) images were also acquired. Subjective scores (cerebral grey matter and white matter clarity scores, clarity scores of cerebral white matter degeneration lesions in relation to the surrounding white matter, and Gibbs artifact scores) and objective metrics [signal-to-noise ratio (SNR), contrast-to-noise ratio (CNR), cerebrospinal fluid signal homogeneity, peak signal-to-noise ratio (PSNR), structural similarity index (SSIM), and natural image quality evaluator (NIQE)] were used to evaluate image quality in different groups. Totally 109 brain regions were segmented and volumes were measured using the uAI Research Portal image analysis tool. Kappa or intraclass correlation coefficient ( ICC) was used to evaluate the agreement of subjective and objective evaluation indexes between the 3D-T 1WI-PI-3 group, 3D-T 1WI-uCS-4.5 group, 3D-T 1WI-uCS-6.9 group, 3D-T 1WI-ACS-3 group, 3D-T 1WI-ACS-5 group, and 3D-T 1WI group. Kappa or ICC value>0.70 was considered as good agreement. Results:The acquisition time for the 3D-T 1WI group, 3D-T 1WI-PI-3 group, 3D-T 1WI-uCS-4.5 group, 3D-T 1WI-uCS-6.9 group, 3D-T 1WI-ACS-3 group, and 3D-T 1WI-ACS-5 group were 527, 204, 169, 95, 133, 90 s, respectively. Subjective evaluation showed that the 3D-T 1WI-uCS-4.5, 3D-T 1WI-ACS-3, and 3D-T 1WI-ACS-5 groups had excellent agreement with the 3D-T 1WI group in terms of the distribution of cases of cerebral grey matter and white matter clarity scores, respectively (all Kappa value=1.000); The distribution of cases of clarity score of cerebral white matter lesions and surrounding white matter in the 3D-T 1WI-PI-3 group, 3D-T 1WI-uCS-4.5 group, and 3D-T 1WI-ACS-3 group were in good agreement with that of the 3D-T 1WI group ( Kappa values of 0.775, 0.701, and 0.777, respectively); the distribution of the number of cases of the Gibbs artifact score of the 3D-T 1WI-uCS-4.5, 3D-T 1WI-ACS-3, and 3D-T 1WI-ACS-5 groups was in good agreement with the 3D-T 1WI group (all Kappa value=1.000). Objective evaluation showed the CNR of the images in the 3D-T 1WI-PI-3, 3D-T 1WI-uCS-4.5, and 3D-T 1WI-uCS-6.9 groups were in good agreement with those of the 3D-T 1WI group ( ICC of 0.720, 0.759, and 0.752, respectively); PSNR and SSIM were in good agreement among the 3D-T 1WI-PI-3 group, 3D-T 1WI-uCS-4.5 group, 3D-T 1WI-uCS-6.9 group, 3D-T 1WI-ACS-3 group, and 3D-T 1WI-ACS-5 group (PSNR: ICC=0.854; SSIM: ICC=0.851). NIQE of 3D-T 1WI-PI-3 group, 3D-T 1WI-uCS-4.5 group, and 3D-T 1WI-ACS-3 group images were in good agreement with the 3D-T 1WI group ( ICC value of 0.866, 0.727, 0.753, respectively). The ICC values of the volume of each segmented brain region among the 3D-T 1WI-PI-3, 3D-T 1WI-uCS-4.5, 3D-T 1WI-uCS-6.9, 3D-T 1WI-ACS-3, 3D-T 1WI-ACS-5 group and the 3D-T 1WI group images showed decreased in order (all ICC≥0.62).

This article reviews the current research status of masculinity in prostate cancer patients, aiming to provide a basis for medical staff to help prostate cancer patients establish positive and diverse masculinity, improve mental health, and also provide reference for promoting relevant research in China.

Objective To explore the ART willingness and influencing factors of male HIV/AIDS patients in a special prison area in Shanghai. Methods The information was collected from face-to-face questionnaire survey of HIV/AIDS patients conducted from July 1, 2019, to December 31, 2019. Data was analyzed by univariate and multivariate analysis. The influence of social demographic characteristics, basic situation of detention, AIDS epidemiology, knowledge of AIDS ART, and family awareness on the willingness of anti-virus treatment was investigated. Results A total of 121 HIV / AIDS patients were investigated in this study. The results of multivariate analysis showed that HIV / AIDS patients who were less likely to receive ART included patients with multiple custody, patients with ART knowledge score less than 8, patients whose family members were unaware of their HIV infection, patients thought that they met the treatment standard but had no symptoms and did not need to take medicine, and patients thought that they could discontinue taking medicine at will. Conclusion A variety of factors have an impact on ART willingness of HIV/AIDS patients in custody. It is suggested that HIV / AIDS patients should be provided with more targeted ART knowledge training and social care and family support as far as possible.

Background::The risk for chronic kidney disease (CKD) is influenced by genetic predisposition, sex, and lifestyle. Previous research indicates that coffee is a potentially protective factor in CKD. The current study aims to investigate whether sex disparity exists in the coffee–CKD association, and whether genetic risk of CKD or genetic polymorphisms of caffeine metabolism affect this association.Methods::A total of 359,906 participants from the UK Biobank who were enrolled between 2006 and 2010 were included in this prospective cohort study, which aimed to estimate the hazard ratios for coffee intake and incident CKD using a Cox proportional hazard model. Allele scores of CKD and caffeine metabolism were additionally adjusted for in a subsample with qualified genetic data ( n = 255,343). Analyses stratified by genetic predisposition, comorbidities, and sex hormones were performed. Tests based on Bayesian model averaging were conducted to ascertain the robustness of the results. Results::Coffee was inversely associated with CKD in a dose-dependent manner. The effects of coffee did not differ across different strata of genetic risk for CKD, but were more evident among slower genetically predicted caffeine metabolizers. Significant sex disparity was observed ( P value for interaction = 0.013), in that coffee drinking was only associated with the risk reduction of CKD in females. Subgroup analysis revealed that testosterone and sex hormone-binding globulin (SHBG), but not estradiol, modified the coffee–CKD association. Conclusions::In addition to the overall inverse coffee–CKD association that was observed in the general population, we could also establish that a sex disparity existed, in that females were more likely to experience the benefit of the association. Testosterone and SHBG may partly account for the sex disparity.

Copy number variations (CNVs), which can affect the role of long non-coding RNAs (lncRNAs), are important genetic changes seen in some malignant tumors. We analyzed lncRNAs with CNV to explore the relationship between lncRNAs and prognosis in bladder cancer (BLCA). Messenger RNA (mRNA) expression levels, DNA methylation, and DNA copy number data of 408 BLCA patients were subjected to integrative bioinformatics analysis. Cluster analysis was performed to obtain different subtypes and differently expressed lncRNAs and coding genes. Weighted gene co-expression network analysis (WGCNA) was performed to identify the co-expression gene and lncRNA modules. CNV-associated lncRNA data and their influence on cancer prognosis were assessed with Kaplan-Meier survival curve. Multi-omics integration analysis revealed five prognostic lncRNAs with CNV, namely

The degree of displacement, oral cleanliness, facial skin allergies and injuries, and comfort of the two groups of patients was compared.Results:The rate of tracheal displacement in the experimental group was mildly 11.2% (11/98), moderately 5.1% (5/98), and the control group was mildly 24.2% (15/62), moderately 14.5% (9/62) and severe 6.5% (4/62). The incidence of facial skin allergy and skin damage was 6.1% (6/98), 0, and the control group was 24.2% (15/62), 11.3% (7/62), the difference was statistically significant ( Z value was -4.021, χ2 value was 24.48, P<0.05). The comfort score of the test group was (1.05±1.01) points, which was significantly higher than (2.10±1.71) points of the control group ( t value was 4.920, P<0.01). Conclusions:The new type of tracheal tube fixation device "dual fixation" for critically ill patients with mechanical ventilation through oral endotracheal intubation is visually beautiful, and has good firmness and comfort. It can effectively reduce the occurrence of adverse events and has good application value.

Na?ve CD4 + T cells differentiate into a variety of T helper (Th) subsets that secrete various cytokines to exert biological effects. Th22 cells, a novel identified CD4 + T cell subset, are distinct from Th1, Th2 and Th17 cell subsets. Th22 cells express chemokine receptors CCR4, CCR6 and CCR10, and secrete multiple cytokines such as IL-22, IL-13 and TNF-α, but not IL-17, IL-4 IFN-γ; and IL-22 is considered as major effector cytokine of Th22. The understanding on functions and differentiation mechanisms of Th22 cells have been constantly improved, and Th22 cells play important roles in human common viral infections. The article reviews the current advances about the characteristics, function, differentiation of Th22 cells, the roles of Th22 cells and the key molecules in several human common viral infections, which would provide novel immune strategies for the prevention and treatment of human viral infection.

OBJECTIVE: To assess the value of chromosomal microarray analysis (CMA) to verify a fetus with partial 18p deletion signaled by non-invasive prenatal testing. METHODS: G-banding chromosomal karyotyping analysis was carried out on amniotic fluid sample of the fetus and peripheral blood samples from the parents. Amniotic DNA was also subjected to CMA analysis. The fetus was also subjected to systematic ultrasound scan. RESULTS: The fetus was found to have a karyotype of 46,XX,18p+. CMA has revealed a 5 Mb deletion at 18p11.32-p11.31, a 2.9 Mb duplication at 18p11.31-p11.23, and a 2.5 Mb duplication at 18p11.23-p11.22. No chromosomal aberration or microdeletion/microduplication was detected in either parent. CONCLUSION Non-invasive prenatal testing and CMA are both sensitive for the detection of chromosomal microdeletions and microduplications. CMA can help with clarification of genotype-phenotype correlation and facilitate prenatal diagnosis and genetic counseling for the family.
