Schizophrenia (SZ) stands as a severe psychiatric disorder. This study applied diffusion tensor imaging (DTI) data in conjunction with graph neural networks to distinguish SZ patients from normal controls (NCs) and showcases the superior performance of a graph neural network integrating combined fractional anisotropy and fiber number brain network features, achieving an accuracy of 73.79% in distinguishing SZ patients from NCs. Beyond mere discrimination, our study delved deeper into the advantages of utilizing white matter brain network features for identifying SZ patients through interpretable model analysis and gene expression analysis. These analyses uncovered intricate interrelationships between brain imaging markers and genetic biomarkers, providing novel insights into the neuropathological basis of SZ. In summary, our findings underscore the potential of graph neural networks applied to multimodal DTI data for enhancing SZ detection through an integrated analysis of neuroimaging and genetic features.

The development of polysaccharide conjugate vaccines, which convert polysaccharide antigens into T-cell-dependent immunogens through covalent conjugation with protein carriers, represents a critical strategy for enhancing immune protection in infants and young children. Globally licensed conjugate vaccines currently employ carrier proteins including Tetanus Toxoid, Diphtheria Toxoid, and Cross-Reacting Material 197. Recent advances have focused on three key areas: novel carrier protein discovery, optimized conjugation strategies, and evaluation of immune interference during co-administration of multivalent formulations. These efforts aim to achieve broader serotype coverage, prolonged protective efficacy, and simplified immunization schedules. This review synthesizes recent progress in carrier protein development, encompassing vaccine design principles, manufacturing processes, safety profiles, and epidemiological effectiveness. Furthermore, it critically examines current selection criteria for carrier proteins, their clinical applications, and persistent challenges, providing strategic insights to inform future conjugate vaccine development and immunization policy optimization in China.

Objective To investigate the effect of transcutaneous electrical acupoint stimulation(TEAS)on postoperative sore throat(POST)in patients undergoing double-lumen bronchial intubation based on general anesthesia.Methods A total of 103 patients,45 males and 58 females,aged 18-64 years,BMI 18-28 kg/m2,ASA physical status Ⅰ-Ⅲ,who received selective operation of double-lumen bronchial intubation under general anesthesia were selected.The patients were divided into two groups using the random number table method:TEAS group(n = 51)and control group(n = 52).In the TEAS group,TEAS on Tiantu acupoint and bilateral Hegu acupoints started 30 minutes before anesthesia induction,and the stimulation lasted until the patients were sent to the recovery room.In the control group,electrodes were placed on the same acupoints without electrical stimulation.The Mallampati grade,number of tracheal intu-bation attempts,compression of cricoid cartilage,resistance during intubation,and double-lumen endobron-chial tube(DLT)retention time were recorded.The incidence and severity of POST,VAS pain scores of sore throat,and the incidence of hoarseness 1 hour,6,and 24 hours after extubation were recorded.Results Compared with the control group,the incidence of POST,the incidence of POST level 1,and VAS pain scores of sore throat were significantly decreased 1 hour,6,and 24 hours after extubation(P＜0.05),the incidence of POST level 2 was significantly decreased 6 hours after extubation in the TEAS group(P＜0.05).There were no significant differences in the situations related to tracheal intubation,and the inci-dence of hoarseness 1 hour,6,and 24 hours after extubation between the two groups.Conclusion The transcutaneous electrical acupoint stimulation on Tiantu acupoint and bilateral Hegu acupoints can signifi-cantly reduce the incidence and severity of postoperative sore throat,and VAS pain scores of sore throat in patients undergoing double-lumen bronchial intubation.

Objective To investigate the effect of vitamin D(VD)on intestinal flora in spontaneously diabetic rats.Methods Zucker diabetic fatty rats(ZDF rats)were randomised to control(Con)group,VD control(VD)group,model(T2DM)group,and VD intervention(VD+T2DM)group.Fasting blood glucose profiles and oral glucose tolerance levels were determined in rats of each group.16S rDNA sequencing was used to assess changes in rat intestinal flora.OTU analysis(Venn diagram),α diversity analysis(chao1,observed species,PD whole tree,and shannon and simpson),βdiversity analysis(principal coordinate analysis(PCoA)),flora structure,and colony species variability analysis(linear discriminant analysis and influence factor(LEfSe)analysis)were also performed.Results VD intervention significantly improved fasting blood glucose levels and insulin resistance in T2DM rats(P＜0.05).α diversity showed no significant differences in chao1,observed species,PD whole tree,and shannon and simpson indices between T2DM and VD+T2DM groups(P＞0.05).β diversity analysis showed that the VD+T2DM group had more species similarity to the Con group than the T2DM group.The dominant bacteria of rat intestinal flora in each group were significantly different.In comparison to the T2DM group,the VD+T2DM group showed a decrease in abundance of Bacteroidetes and increases in abundances of Firmicutes and Clostridium XIVa.Conclusions VD improves fasting glucose elevation and insulin resistance in T2DM rats.VD improves the structure of intestinal flora,decreases Bacteroidetes,and elevates Firmicutes and Clostridium XIVa abundances in T2DM rats.

Osteoporotic proximal humeral fracture (OPHF) is one of the common osteoporotic fractures in the aged, with an incidence only lower than vertebral compression fracture, hip fracture, and distal radius fracture. OPHF, secondary to osteoporosis and characterized by poor bone quality, comminuted fracture pattern, slow healing, and severely impaired shoulder joint function, poses a big challenge to the current clinical diagnosis and treatment. In the field of diagnosis, treatment, and rehabilitation of OPHF, traditional Chinese and Western medicine have accumulated rich experience and evidence from evidence-based medicine and achieved favorable outcomes. However, there is still a lack of guidance from a relevant consensus as to how to integrate the advantages of the two medical systems and achieve the integrated diagnosis and treatment. To promote the diagnosis and treatment of OPHF with integrated traditional Chinese and Western medicine, relevant experts from Orthopedic Expert Committee of Geriatric Branch of Chinese Association of Gerontology and Geriatrics, Youth Osteoporosis Group of Orthopedic Branch of Chinese Medical Association, Osteoporosis Group of Orthopedic Surgeon Branch of Chinese Medical Doctor Association, and Osteoporosis Committee of Shanghai Association of Integrated Traditional Chinese and Western Medicine have been organized to formulate Expert consensus on the diagnosis and treatment of osteoporotic proximal humeral fracture with integrated traditional Chinese and Western medicine ( version 2024) by searching related literatures and based on the evidences from evidence-based medicine. This consensus consists of 13 recommendations about the diagnosis, treatment and rehabilitation of OPHF with integrated traditional Chinese medicine and Western medicine, aimed at standardizing, systematizing, and personalizing the diagnosis and treatment of OPHF with integrated traditional Chinse and Western medicine to improve the patients ′ function.

Acute pancreatitis is a common acute abdomen with a variety of causes and natural course.The incidence rate is increasing year by year.Some patients may develop severe acute pancreatitis,with serious complications and a high risk of death.Therefore,early prediction of the severity of the patient's condition and active treatment are beneficial to reduce the severity and mortality rate of patients and improve the prognosis of patients.In order to predict the severity of acute pancreatitis,many prediction methods have emerged in the clinic,including acute C-reactive protein,urea nitrogen,thyroid hormone,hematocrit,inflammatory factors,visceral fat area,pancreatic necrosis volume,APACHEⅡ,Ranson score,BISAP,EPIC,MCTSI,etc.This article summarizes the serological indicators,imaging methods and scoring systems that can be used to predict severe acute pancreatitis,focusing on their characteristics and limitations.

Objective:To analyze the feasibility and clinical efficacy of reperfusion-expanding-thrombectomy-stenting (RETS) technique in the endovascular treatment of acute carotid artery tandem lesion.Methods:The general clinical data of 88 patients with carotid artery tandem lesion who received emergency endovascular treatment from January 2018 to December 2020 in Department of Neurology, Linyi People′s Hospital were reviewed, the Modified Rankin Scale (mRS) was used as the evaluation standard for the prognosis of patients at 90 days after endovascular treatment, and the clinical data were analyzed, including the recanalization (modified thrombolysis in cerebral infarction ≥2b), perioperative complications and 90-day prognosis, and good prognosis was defined as a mRS score of 0-2.Results:A total of 88 patients with tandem carotid artery disease were included,48 of whom were treated with RETS technique, 40 were treated with anterograde approach. Compared with antegrade recanalization, RETS technique had significant differences in the time from puncture to recanalization [(72.06±17.29) min vs (98.88±26.09) min, t=-5.56, P<0.001] and the primary recanalization rate [35/48(73.0%) vs 21/40(52.5%),χ2=3.93 ,P=0.047], with statistically significant difference. There was no significant difference in clinical prognosis and surgical complications between the two methods (all P>0.05). Conclusions:RETS technique can shorten the operation time and increase the primary recanalization rate. RETS technique is safe and feasible for the treatment of carotid tandem lesions.

Intrinsically disordered proteins (IDPs) are proteins or protein regions that fail to get folded into definite three-dimensional structures but participate in various biological processes and perform specific functions. Defying the traditional protein "sequence-structure-function" paradigm, they enrich the protein "structure-function" diversity. Ubiquitous in organisms, they show extreme hydrophilicity, charged amino acids, and highly repetitive amino acid sequences, with simple arrangement. As a result, they feature highly variable binding affinities and high coordination, which facilitate their functions. IDPs play an important role in cell stress response, which can improve the tolerance to a variety of stresses, such as freezing, high salt, heat shock, and desiccation. In this study, we briefed the characteristics, classifications, and identification of IDPs, summarized the molecular mechanism in improving cell stress resistance, and described the potential applications.
