In February 2025, a local cluster outbreak caused by the D8 genotype Measles virus (MV) was first discovered in Henan Province. Epidemiological investigations and laboratory testing were conducted, including the collection of serum and throat swabs for MV IgM antibody and nucleic acid detection, virus isolation and genetic homology analysis. Measures such as close contact tracing, vaccination rate assessment and supplementary immunization activities were implemented, successfully preventing broader community transmission. A total of three cases were reported during the outbreak, including one imported-related adolescent and two secondary local adult cases. All cases presented with typical symptoms such as fever and rash. Both adult cases were complicated by pneumonia, with one case developing into severe pneumonia. MV genotyping showed that the two secondary cases were both the D8 genotype, with the viral sequences being completely homologous to the Kazakhstan strain. Among the close contacts, 98.2% were adults, and 142 individuals received emergency vaccination.

Sleep disorders are characterized by abnormal amounts of sleep and unusual behavior during sleep.Long-term sleep disorders can lead to the disruption of normal social functioning or neurological conditions.In recent years,the role of sound wave therapy in improving sleep quality has attracted much attention.This article aims to review the research progress related to the role of sound wave therapy in enhancing sleep quality,cognitive function,and alleviating fatigue in patients with sleep disorders in hopes of contributing to clinical applications.

Ischemic stroke （CIS） refers to ischemic necrosis or softening of localized brain tissue caused by cerebral blood circulation disorders， ischemia and hypoxia. The incidence of CIS is the highest among cerebrovascular diseases. Reduced supply of oxygen and nutrients leads to severe loss of neurons and deficits in brain function in stroke patients. Developing treatments for ischemic stroke remains an important challenge in clinical medicine. The antioxidant N-acetylcysteine （NAC） is a precursor of glutathione， and evidence from animal models of ischemic stroke and some clinical studies suggest that NAC can effectively protect the brain from ischemic damage. In this paper， the mechanism of NAC in CIS is described from various aspects， such as anti-oxidation， inhibition of inflammation， protection of cerebral nerve and mitochondrial function， stabilization of arterial plaque and thrombolytic function， aiming to explore the relationship between NAC and CIS in depth from the basic level， and to provide a theoretical basis for the further application of NAC in the prevention and treatment of patients with ischemic stroke.

OBJECTIVE To investigate the mechanism of anti-colorectal cancer growth and metastasis-related effects of Astraga-lus mongholicus Bunge-Curcuma aromatica-Paridis Rhizoma(Qi-Zhu-Zao)pairing through PERK/eIF2α/ATF4 signaling pathway mediating endoplasmic reticulum stress.METHODS Twenty-four BALB/c male mice were randomly divided into sham-operated group,model group,5-FU(5-fluorouracil)group(25 mg·kg-1),and Qi-Zhu-Zao high dose group(5.85 g·kg-1),Qi-Zhu-Zao low dose group(2.925 g·kg-1)(n=6)to construct a mouse model of colorectal cancer in situ transplantation tumor,and the inter-vention effect of Qi-Zhu-Zao combination on tumor growth was assessed by the change of tumor volume size after 15 days of administra-tion;the intervention effect of Qi-Zhu-Zao combination on tumor growth was assessed by H&E.Pathological staining was used to eval-uate the effect of Qi-Zhu-Zao combination on the liver and tumor tissues of mice.The changes of MDA,SOD and GSH-Px levels were detected by enzyme-linked immunosorbent assay(ELISA);the expression of PERK/eIF2α/ATF4 signaling pathway and EMT-related proteins were detected by protein immunoblotting(Western blot).RESULTS Compared with the model group,the tumor volume was significantly reduced(P＜0.000 1),liver and spleen metastases were less pronounced in the Qi-Zhu-Zao high-dose group,and his-topathological staining results of liver tissue and tumor produced changes in oxidative stress indicators SOD,MDA,and GSH-Px,up-regulation of ER stress-related proteins p-PERK,p-IF2α,and ATF4,etc.,upregulated the protein expression levels of E-Cadherin,downregulated N-Cadherin,Vimentin,and Snail,and inhibited the EMT process(P＜0.01 or P＜0.05).CONCLUSION In this paper,we investigated the regulatory mechanism related to the inhibition of colorectal cancer growth and metastasis by the combination of Qi-Zhu-Zao trigonal medicine,and demonstrated that it may inhibit the growth and metastasis of colorectal cancer by activating the PERK/eIF2α/ATF4 pathway to induce sustained ER stress and affect the EMT process of colorectal cancer.

Lipophagy, the selective engulfment of lipid droplets (LDs) by autophagosomes for lysosomal degradation, is critical to lipid and energy homeostasis. Here we show that the lipid transfer protein ORP8 is located on LDs and mediates the encapsulation of LDs by autophagosomal membranes. This function of ORP8 is independent of its lipid transporter activity and is achieved through direct interaction with phagophore-anchored LC3/GABARAPs. Upon lipophagy induction, ORP8 has increased localization on LDs and is phosphorylated by AMPK, thereby enhancing its affinity for LC3/GABARAPs. Deletion of ORP8 or interruption of ORP8-LC3/GABARAP interaction results in accumulation of LDs and increased intracellular triglyceride. Overexpression of ORP8 alleviates LD and triglyceride deposition in the liver of ob/ob mice, and Osbpl8-/- mice exhibit liver lipid clearance defects. Our results suggest that ORP8 is a lipophagy receptor that plays a key role in cellular lipid metabolism.

In order to construct the online teaching mode of clinical clerkship course and improve the online clerkship teaching system of clinical medicine in China, based on the "3P" model, a complete set of online clinical clerkship mode has been constructed from three links of teaching, pre-class preparation, classroom teaching and after-class evaluation, and applied to clinical teaching practice of Internal Medicine. The practice suggests that students are highly satisfied and the teaching effect is good, which provides a new idea for the reform of online clerkship teaching of clinical medicine.

Neuroinflammation is a key contributor to the pathogenic cascades induced by hypoxic-ischemic (HI) insult in the neonatal brain. AD-16 is a novel anti-inflammatory compound, recently found to exert potent inhibition of the lipopolysaccharide-induced production of pro-inflammatory and neurotoxic mediators. In this study, we evaluated the effect of AD-16 on primary astrocytes and neurons under oxygen-glucose deprivation (OGD) in vitro and in mice with neonatal HI brain injury in vivo. We demonstrated that AD-16 protected against OGD-induced astrocytic and neuronal cell injury. Single dose post-treatment with AD-16 (1 mg/kg) improved the neurobehavioral outcome and reduced the infarct volume with a therapeutic window of up to 6 h. Chronic administration reduced the mortality rate and preserved whole-brain morphology following neonatal HI. The in vitro and in vivo effects suggest that AD-16 offers promising therapeutic efficacy in attenuating the progression of HI brain injury and protecting against the associated mortality and morbidity.

Objective : To investigate the relationship between vitamin D receptor (VDR) gene polymorphisms and the clinical prognosis of acute pancreatitis (AP) , and to provide a genetic basis for early identification of critically ill patients. Methods : A total of fourteen single nucleotide polymorphisms (SNPs) on the VDR gene were detected in 508 AP patients by using improved ligase detection reaction (imLDR) technology. Unconditional Logistic regression analysis was used to explore the association of VDR gene polymorphisms with outcome ( sepsis/severe AP/death) of AP patients after adjusting for age , sex , body mass index(BMI) , smoking and drinking status and APACHE II score under different genetic models. Results : Rs12721375 GA/AA genotype had a lower risk of sepsis than GG (P = 0. 02) and the A allele had a lower risk of sepsis than G (P = 0. 009) . Rs2853559 GA and GA/AA had higher risks of sepsis than GG (P = 0. 022 and 0. 026 respectively) . Rs11168287 AA had a higher risk of severe AP than GG and GG/GA (P = 0. 030 and 0. 022 respectively) . Rs2853559 AA genotype had a higher risk of severe AP than GG and GG/GA ( P = 0. 022 and 0. 021 respectively) . The risk of death of rs11168283 CT/TT genotype was lower than that of CC (P = 0. 046) . Conclusion VDR gene polymorphisms are related to the clinical outcome of AP patients in Chinese Han population. VDR gene is involved in the progression of AP.
