ObjectiveTo investigate the characteristics of gray matter structure and clinical symptoms in patients with Alzheimer's disease （AD） comorbid with apathy （AD-A）. MethodsThe study included 30 patients with AD-A， 30 AD disease patients without apathy （AD without apathy， AD-NA）， and 30 healthy controls （HCs） matched in gender， age， and years of education. All participants underwent a comprehensive neuropsychological assessment and magnetic resonance imaging （MRI） scans. Voxel-based morphometry （VBM） was used to analyze changes in gray matter volume among the three groups. Additionally， the correlation between the identified abnormal brain regions and apathy scale scores was analyzed. ResultsThere were no statistically significant differences among the three groups in terms of age， gender， years of education， or total intracranial volume. Compared with the HCs group， both the AD-A and AD-NA groups showed significantly lower scores in cognitive function （P<0.001）. The AD-A group exhibited significantly higher apathy scale scores compared with the AD-NA group （P<0.001）. Compared with the AD-NA group， the AD-A group showed reduced gray matter volume in the bilateral caudate nucleus， left orbitofrontal cortex， lingual gyrus， inferior frontal gyrus， superior frontal gyrus， entorhinal cortex， right middle frontal gyrus and posterior cingulate cortex （FWE-corrected， P<0.05 for all）. Compared with the HCs group， the AD-A group exhibited reduced gray matter volume in the bilateral middle temporal gyrus， left fusiform gyrus， calcarine sulcus， postcentral gyrus， right inferior frontal gyrus and supramarginal gyrus （FWE-corrected， P<0.05 for all）. Compared with the HCs group， the AD-NA group showed reduced gray matter volume in the left precuneus， inferior temporal gyrus， and right inferior temporal gyrus （FWE-corrected， P<0.05 for all）. In the AD-A group， changes in the gray matter volume of the left caudate nucleus （r= -0.557， P=0.002） and right middle frontal gyrus （r=-0.620， P=0.001） were negatively correlated with the apathy evaluation scale （AES） scores. ConclusionPatients in the AD-A group exhibited significant atrophy in the frontal-temporal-basal ganglia circuit， and the degree of gray matter atrophy was correlated with the severity of apathy.

[摘 要] 目的：探讨胰岛素样生长因子2 mRNA结合蛋白3（IGF2BP3）、尿苷二磷酸-葡萄糖醛酸脱羧酶1（UXS1）在肝细胞癌（HCC）中的表达特征、预后价值及两者协同作用的分子机制。方法：整合UALCAN、cBioPortal、ENCORI、TISCH2、GDSC等公共数据库的转录组数据，对IGF2BP3和UXS1进行表达、预后评估、功能富集及药物敏感性等分析。收集GEO数据库的单细胞RNA测序（scRNA-seq）数据，分析细胞通信、单细胞代谢评分，系统解析IGF2BP3-UXS1轴在HCC中的具体作用。结果：IGF2BP3、UXS1在HCC组织中均显著高表达，且高表达患者总生存期显著缩短（均P < 0.05）。采用CRISPP技术敲除IGF2BP3或UXS1后，多种HCC细胞的增殖能力受到明显抑制。scRNA-seq分析揭示了IGF2BP3、UXS1在肝细胞等细胞类型中的广泛表达分布，前者在细胞分化晚期上调，后者则在细胞分化早、中期高表达。IGF2BP3、UXS1高表达组均显著激活了MIF通路，同时IGF2BP3的高表达削弱了成纤维细胞的相互作用，而UXS1的高表达则增强了T细胞的信号转导功能。IGF2BP3与UXS1在表达相关性中存在显著的正相关（r = 0.432，P < 0.05）。沉默IGF2BP3结合位点会导致UXS1表达水平变化（F = 0.333）。功能富集分析提示，IGF2BP3与UXS1协同调控能量代谢、蛋白质翻译等生物学过程。在IGF2BP3或UXS1高表达的细胞亚群中，发现两者与多个糖代谢相关通路存在显著关联。IGF2BP3、UXS1高表达的患者对优普色替等药物表现出显著的敏感性，还对药物那维托克等表现出显著的耐药性。结论： IGF2BP3、UXS1在HCC中高表达，两者通过调控糖代谢重编程的协同作用促进HCC恶性生物学行为。

Objective To explore the efficacy of hypofractionated radiotherapy at different time intervals after surgery for keloid,and to analyze the factors affecting the efficacy.Methods A total of 76 patients who underwent 20 Gy/5 postoperative radiotherapy regimen in the Fifth Affiliated Hospital of Zhengzhou University from January 2021 to June 2023 were selected as study subjects,and a total of 100 keloids were divided into effective group(n=79)and recurrence group(n=21).Regular follow-up and record of the patients after radiotherapy treatment effect and adverse effects,and multivariate Logistic was used to analyze factors of recurrence in keloid patients.Results Multivariate Logistic regression analysis found that postoperative radiotherapy time and scar incision length were related to recurrence after treatment,radiotherapy within 7h of surgery was an independent risk factor for recurrence after treatment(OR＞1,P=0.022),and scar incision≤5cm was an independent protective factor for recurrence after treatment(OR＜1,P=0.028).Conclusion Surgical excision combined with hypofractionated radiotherapy is one of the effective measures to prevent and treat keloid recurrence,though keloids on the trunk may need more effective treatment options.The recurrence rate of radiotherapy initiated 7-48h after surgery is relatively the lowest,and it is worthy of clinical promotion and application.

Objective:To investigate the feasibility of improving quality of life through outcome self-reporting and clinical intervention based on the Ureteral Stent Symptom Questionnaire(USSQ)for patients with upper tract urolithiasis.Methods:We enrolled 106 patients with upper urinary tract calculi from June 2023 to June 2024 who underwent ureteral stent placement at The First Affiliated Hospital of Chongqing Medical University.We applied the USSQ to monitor the patients'outcomes through their self-reports,and used the data to inform clinical interventions.The feasibility of this USSQ-based approach for improving patients'quality of life was evalu-ated.Results:The main symptoms after ureteral stent placement were pain and hematuria,while frequency,urgency,fever,and sexual problems were less common.The USSQ score was highest on the third day after operation,and thereafter declined in all the dimensions.except the additional problem.After intervention,the total USSQ score(57.5±10.1 vs.51.6±8.9,t=2.981,P=0.004)and urinary symptom score(30.8±5.3 vs.26.7±5.6,t=3.478,P<0.001)were significantly decreased.USSQ-based outcome self-reporting and clinical intervention could reduce symptom scores and improve patients'quality of life.Conclusion:USSQ-based outcome monitoring and management are feasible and effective for improving the quality of life of patients with upper tract urolithiasis.

Turning to critical illness is a common stage of various diseases and injuries before death. Patients usually have complex health conditions, while the treatment process involves a wide range of content, along with high requirements for doctor′s professionalism and multi-specialty teamwork, as well as a great demand for time-sensitive treatments. However, this is not matched with critical care professionals and the current state of medical care in China. Telemedicine, which shortens the distance of medical professionals and the gap of disease diagnosis and treatments in various regions through electronic information, can effectively solve the current problem. Therefore, there is an urgent need to develop a standardized, high-quality visualization telemedicine round system .Therefore, experts have been organized to search domestic and foreign literature on telemedicine round for critically ill patients and to form this consensus based on clinical experiences so as to further improve the level of critical care treatments in regions.

Alzheimer′s disease is a serious neurodegenerative disorder. Approximately 80% to 90% of patients are accompanied by behavioral and psychological symptoms of dementia (BPSD), which manifest as a series of behavioral, psychological and mental abnormalities. These abnormalities can accelerate the cognitive deterioration and premature death of patients, and thus are regarded as important clinical symptoms. However, the pathogenesis of BPSD is still unknown, and treatment methods are limited. The pathogenesis of BPSD from the perspective of neuroimaging and pathophysiology, and possible treatment measures were analyzed in this article, in order to provide references for the early diagnosis and treatment of BPSD.

Background With economic development and globalization, shift work has become prevalent across industries. Its relationship with type 2 diabetes mellitus (T2DM) attracts increasing attention. Objective To thoroughly explore the relationship between shift work and T2DM, and analyze the impacts of specific shift patterns on T2DM, so as to provide a basis for formulating reasonable shift schedules. Methods We conducted a 1:2 matched case-control study among adults (20-60 years) who ordered occupational health examinations at the Wuxi No.8 People's Hospital from November to December 2023. The case group comprised 200 T2DM patients, while the controls were 400 age-stratified matched non-diabetic individuals. General demographic characteristics, behavioral habits, medical history, and shift work exposure data (including shift patterns, frequency, and length of service) 5 years prior to diagnosis were collected through standardized questionnaires. Logistic regression adjusted for selected confounders was employed to evaluate the association between shift work and T2DM. Results The logistic regression analysis demonstrated that shift work was associated with an increased risk of T2DM. After adjusting for confounding factors, shift workers had a 3.55 times higher risk of being diagnosed T2DM compared to non-shift workers (OR=3.55, 95%CI: 1.026, 12.263). The risk varied across different shift patterns, and the three-shift two-rotation system showed the highest risk (OR=4.17, 95%CI: 1.921, 9.035), followed by the two-shift system (OR=2.94, 95%CI: 2.016, 4.281) and four-shift three-rotation system (OR=2.66, 95%CI: 1.611, 6.093). Workers with more than 3 monthly shift days had a 2.74-fold increased risk (95%CI: 1.658, 4.512) compared to non-shift workers. Additionally, working more than 8 h daily (OR=1.74, 95%CI: 1.185, 2.562) and having more than 20 years of service (OR=2.51, 95%CI: 1.581, 3.976) were both significantly associated with a higher T2DM risk. The trend tests revealed that each incremental increase in monthly shift days and length of service elevated T2DM risk by 2.61 times (95%CI: 1.813, 3.765) and 1.49 times (95%CI: 1.147, 1.931), respectively (P<0.05). Conclusion Shift work is an independent risk factor for T2DM, with three-shift two-rotation system posing the highest risk. Shift frequency, daily working hours, and length of service are all significant factors affecting the risk of T2DM. These findings support industry-specific shift policy reform and targeted glucose monitoring and health interventions are recommended for workers engaged in high-risk shift patterns (e.g., three-shift two-rotation system, frequent shifts) and those with prolonged shift work history (>20 years).

Objective To explore the mechanism of Tongdu Xingshen acupuncture,the clinical efficacy,systemic inflammatory response,blood-brain barrier and intestinal flora in patients with cognitive impairment after ischemic stroke(IS)were studied.Methods Thirty patients(3 cases shedding)with cognitive impairment after IS were included as the disease group,including patients before treatment as the disease group,patients after Tongdu Xingshen acupuncture treatment as the electroacupuncture group,and 30 healthy controls(3 cases shedding)were included as the healthy group.In the electroacupuncture group,on the basis of the basic treatment,Tongdu Xingshen acupuncture was applied,which was 30 min each time,once a day for 14 days.The MMSE,MoCA and MBI scores of the three groups were observed.The fecal and serum samples from all study subjects were collected,and 16S rDNA sequencing technology and ELISA were used to detect the changes of proinflammatory factors IL-6,IL-1β,TNF-α and S100β in serum in intestinal flora and feces.Results Compared with the healthy group,the MMSE,MoCA,and MBI score of patients in the disease group decreased significantly(P<0.05),serum proinflammatory factors and S100β protein content increased significantly(P<0.05),and the Shannon index(P<0.01)and Simpson index(P<0.001)increased significantly.Compared with the disease group,the MMSE,MoCA,and MBI score of the EA group increased significantly(P<0.05),the serum levels of proinflammatory factors and S100β decreased significantly(P<0.05),Shannon index and Simpson index decreased(P>0.05).The dominant bacterial flora in the healthy group mainly included Bacteroides,Bifidobacterium,Bacteroides,Faecalibacterium,Bifidobacteriaceae,Ruminococcaceae,and Bacteroides and other beneficial bacteria(P<0.05).The dominant flora in the disease group included Proteobacteria,Enterobacteriaceae,Escherichia,Klebsiella and other opportunistic bacteria(P<0.05),while the dominant flora in the EA group was consistent with the healthy group,the relative abundance of beneficial bacteria increased significantly(P<0.05),and the relative abundance of opportunistic bacteria decreased significantly(P<0.05).Spearman correlation analysis found that beneficial bacteria were positively correlated with clinical efficacy related indicators,but with serum proinflammatory factors and the content of S100β was negatively correlated.Conclusion Tongdu Xingshen acupuncture can regulate the diversity of intestinal flora to increase the abundance of Bacteroides,Bifidobacterium,Faecalibacterium,and other beneficial bacteria,regulate the intestinal microecological balance,Thereby regulating systemic inflammation and blood-brain barrier function,which plays a role in improving cognitive function.

Metformin has been demonstrated to attenuate hyperglycaemia by modulating the gut microbiota. However, the mechanisms through which the microbiome mediates metformin monotherapy failure (MMF) are unclear. Herein, in a prospective clinical cohort study of newly diagnosed type 2 diabetes mellitus (T2DM) patients treated with metformin monotherapy, metagenomic sequencing of faecal samples revealed that Phocaeicola vulgatus abundance was approximately 12 times higher in nonresponders than in responders. P. vulgatus rapidly hydrolysed taurine-conjugated bile acids, leading to ceramide accumulation and reversing the improvements in glucose intolerance conferred by metformin in high-fat diet-fed mice. Interestingly, C22:0 ceramide bound to mitochondrial fission factor to induce mitochondrial fragmentation and impair hepatic oxidative phosphorylation in P. vulgatus-colonized hyperglycaemic mice, which could be exacerbated by metformin. This work suggests that metformin may be unsuitable for P. vulgatus-rich T2DM patients and that clinicians should be aware of metformin toxicity to mitochondria. Suppressing P. vulgatus growth with cefaclor or improving mitochondrial function using adenosylcobalamin may represent simple, safe, effective therapeutic strategies for addressing MMF.

Objective:To examine the clinical effects of the SCERTS model-based peer-mediated intervention (PMI) on the social skills of children with autism spectrum disorder (ASD) and provide new approaches to the rehabilitation treatment of ASD children.Methods:A randomized controlled study.A total of 120 children with mild-to-moderate ASD diagnosed Xi′an Traditional Chinese Medicine Hospital of Encephalopathy between April 2023 and April 2024 were selected.They were assigned to either the experimental or control group using the random number table method, with 60 cases in each group.The experimental group was treated with the SCERTS model-based PMI, whereas the control group underwent conventional rehabilitation training, comprising cognitive, language and behavioural interventions, acupuncture and other techniques.Changes in Social Responsiveness Scale (SRS), Autism Social Skills Scale (ASSS) and Autism Treatment Evaluation Checklist (ATEC) scores were observed in the 2 groups of children before and after treatment.The statistical analyses were performed using a paired-samples t-test for intra-group comparisons and an independent-samples t-test for inter-group comparisons. Results:Following 12 weeks of intervention, the SRS and ATEC scores decreased while the ASSS scores increased after treatment in both groups.The differences were statistically significant (all P<0.05).The SRS [(83.25±14.56) points] and ATEC [(79.41±15.36) points] of the experimental group were lower than those of the control group [SRS(89.80±12.69) points, ATEC(85.95±16.13) points].The ASSS score of the experimental group was higher than that of the control group [(112.77±22.42) points vs.(103.80±24.13) points] ( t=2.627, 2.274, -2.109; all P<0.05). Conclusions:The SCERTS model-based PMI is an efficacious approach for the improvement of social skills in ASD children, and thus merits further investigation and application.
