Objective:To investigate the protective mechanism of cerium oxide nanoparticles(CeO2 NPs)against acute pancreatitis(AP),with a focus on their antioxidant and anti-inflammatory properties.Methods:CeO2 NPs were characterized by transmission elec-tron microscopy(TEM)and dynamic light scattering.In in vitro experiments,cell counting Kit-8(CCK-8)assay,flow cytometry,and Western blotting were used to validate the role of CeO2 NPs in preventing the apoptosis of pancreatic acinar cells.In in vivo experi-ments,C57BL/6 mice were divided into control group,AP group,AP+CeO2 group,SAP group,and SAP+CeO2 group to investigate the mechanism of action of CeO2 NPs in alleviating inflammation and oxidative stress in AP mice.Results:CeO2 NPs demonstrated rela-tively good stability and biocompatibility,with a particle size of(50±4)nm on TEM.In vitro experiments showed that CeO2 NPs sig-nificantly reduced the apoptosis of pancreatic acinar cells by alleviating lipid peroxidation and maintaining mitochondrial membrane potential.In vivo experiments showed that CeO2 NPs could reduce the serum levels of amylase,lipase,and inflammatory cytokines(in-terleukin-6 and tumor necrosis factor-α).This result might be related to the regulation of the IKK/P53/Bcl-2 pathway.CeO2 NPs re-duced the production of reactive oxygen species and enhanced anti-oxidant response by regulating the Nrf-2 signaling pathway.Con-clusion:CeO2 NPs exert anti-inflammatory and antioxidant effects by regulating the IκB kinase/tumor protein p53/B-cell lymphoma 2(IKK/P53/bcl-2)and nuclear factor erythroid 2-related(Nrf-2)signaling pathways,thereby showing promising potential for the treatment of AP.

OBJECTIVE: To explore the clinical characteristics and genetic etiology of a child with Oral-facial-digital syndrome type Ⅰ(OFDSⅠ). METHODS: A child with OFDSⅠ who received treatment at the Women and Children's Hospital Affiliated to Ningbo University in March 2023 was selected as the study subject. A retrospective research method was used to collect the clinical data of the child. Peripheral venous blood samples were collected from the child, her parents and sister. Genomic DNA was extracted, and whole exome sequencing (WES) was performed. Candidate variants were validated using Sanger sequencing for familial verification. According to the Standards and Guidelines for the Interpretation of Sequence Variants developed by the American College of Medical Genetics and Genomics (ACMG) (hereinafter referred to as the "ACMG Guidelines"), the pathogenicity of the candidate variant was rated. This study was approved by the Medical Ethics Committee of Ningbo University Affiliated Women and Children's Hospital (Ethic No.: EC 2024-063). RESULTS: The child was a prematurely born female with deformities of the oral cavity, fingers, and toes. She was admitted to the Neonatal Department of the Hospital where she was born due to shortness of breath 15 minutes after birth. The WES results indicated that the child has harbored a heterozygous c.710dup (p.Y238Vfs*2) frameshifting variant of the OFD1 gene. Sanger sequencing confirmed that neither of the child's parents nor her sister had carried the same variant. According to the ACMG guidelines, the variant was rated as pathogenic (PVS1+PS4_Moderate+PM2-Supporting+PM6_Supporting+PP4). CONCLUSION Children with OFDSⅠ have clinical features such as oral, finger, and toe deformities. The c.710dup (p.Y238Vfs*2) variant of the OFD1 gene probably underlay the OFDSⅠ in this child. Above result has enriched the mutational spectrum of the OFD1 gene.

This paper summarized the key points and methods in terms of the establishment of the guideline working group and the management of conflict of interests， trying to provide reference for the development of clinical practice guidelines for Chinese patent medicine （CPM）. The establishment of the working group is the first important step for developing CPM guidelines. Considering the characteristics of the clinical practice guidelines for CPM， this study suggests that the three key elements of ‘multidisciplinarity’， ‘clinical relevance’ and ‘geographical representativeness’ should be put focus on when forming the working group. The guideline advisory committee， clinical expert group， evidence systematic evaluation group， secretary group and the external review group should be established. All group members should clarify the conflict of interest， and the process and management method of the conflict of interest should be clearly reported.

Standardized reporting is a crucial factor affecting the use of patient guidelines （PGs）， particularly in the reporting and presentation of recommendations. This paper introduced the current status of PG reporting， including the research on PG content and presentation formats， and provided comprehensive recommendations for PG reporting from aspects such as overall framework， recommendations， presentation format， and readability. First， the presentation of PG recommendations should include clearly defined clinical questions， recommendations and their rationale， and guidance on how patients should implement the interventions； for specific content in the PG， such as level of evidence， level of recommendation， it is recommended to explain in text the reasons for giving different levels of recommendation， i.e.， to present the logic behind giving the level of recommendation to the patient； additional information needed in the recommendation framework should be supplemented by tracing references or authoritative textbooks and literature that support the recommendations. Subsequently， the PG text should be written based on the Reporting Checklist for Public Versions of Guidelines （RIGHT-PVG） reporting framework. Finally， to enhance readability and comprehension， it is recommended to refer to the Patient Education Materials Assessment Tool （PEMAT） for translating PG content. To enhance the readability of PGs， it is suggested to present the PG content in a persona-lized and layered manner.

Since the concept of patient versions of guidelines （PVGs） was introduced into China， several PVGs have been published in China， but we found that there is a big difference between the concept of PVG at home and abroad， and the reason for this difference has not been reasonably explained， which has led to ambiguity and even misapplication of the PVG concept by guideline developers. By analyzing the background and purpose of PVGs， and the understanding of the PVG concept by domestic scholars， we proposed the term patient guidelines （PGs）. This refers to guidelines developed under the principles of evidence-based medicine， centered on health issues that concern patients， and based on the best available evidence， intended for patient use. Except for the general attribute of providing information or education， which is typical of common health education materials， PGs also provide recommendations and assist in decision-making， so PGs include both the patient versions of guidelines （PVG） as defined by the Guidelines International Network （GIN） and "patient-directed guidelines"， i.e. clinical practice guidelines resulting from the adaptation or reformulation of recommendations through clinical practice guidelines.

At present， the process and methodology of patient guidelines （PGs） development varies greatly and lacks systematic and standardised guidance. In addition to the interviews with PG developers， we have sorted out the relevant methodology for the adaptation and development of existing clinical practice guideline recommendations and facilitated expert deliberations to achieve a consensus， so as to finally put forward a proposal for guidance on the process and methodology for the development of PGs. The development of PGs can be divided into the preparation stage， the construction stage， and the completion stage in general， but the specific steps vary according to the different modes of development of PGs. The development process of Model 1 is basically the same as the patient version of the guideline development process provided by the International Guidelines Network， i.e.， team formation， screening of recommendations， guideline drafing， user testing and feedback， approval and dissemination. The developer should also first determine the need for and scope of translating the clinical practice guideline into a patient version during the preparation phase. Model 2 adds user experience and feedback to the conventional clinical practice guideline development process （forming a team， determining the scope of the PG， searching， evaluating and integrating evidence， forming recommendations， writing the guideline， and expert review）. Based on the different models， we sort out the process and methods of PG development and introduce the specific methods of PG development， including how to identify the clinical problem and how to form recommendations based on the existing clinical practice guidelines， with a view to providing reference for guideline developers and related researchers.

Objective:To analyze the epidemiological characteristics of norovirus (NoV) acute gastroenteritis (AGE) outbreaks caused by GII.17[P17] variant in China, 2022.Methods:Information and specimens of AGE outbreaks between January and December 2022 were collected. NoV RNA was detected in all specimens by real-time RT-PCR. The viral genome of the positive specimens were amplified, sequenced and analyzed.Results:Between January and December 2022, 360 AGE outbreaks were reported cumulatively, of which 266 outbreaks successfully obtained genotype results. GII.17 [P17] was one of the main genotypes and detected in 34 outbreaks (12.78%, 34/266), with the highest number of outbreaks detected in spring (6 outbreaks in March and 7 outbreaks in May), mainly in childcare facilities and primary schools (61.76%, 21/34). According to the result of NoV genotype analysis in different age groups, 14 strains of GII.17 [P17] in this study belonged to Cluster III b and SC III branch of Cluster III (Kawasaki308) in the capsid region and polymerase region, respectively, and both belonged to the same cluster as the variant strain (GZ41621 strain) that caused the NoV AGE outbreaks in China during the 2014/15 season. Compared to reference strains of Cluster I, Cluster II and Cluster III a, Cluster III b was provided with 22 amino acid mutations in VP1. The main amino acid changes in the subgroup of Cluster III b including the virus strains isolated in this study were at T294I and Q299R of antigen epitope A, an insertion mutation occurred at antigen epitope D, H353Q at the site I of the human histo-blood group antigen receptor binding site. The selection pressure analysis detected a large number of negative selection sites, indicating that negative selection plays an important role in the evolution of VP1 genes.Conclusions:GII.17 [P17] was one of the primary genotypes responsible for NoV diarrhea outbreaks in China in 2022. Phylogenetic analysis had revealed that it still belonged to the same cluster as the novel GII.17 [P17] variant (strain GZ41621) that caused NoV epidemics in China during the 2014/15 season, exhibiting minor amino acid variations at the potential epitope.

Objective:To observe any effect of combining vibroacoustic therapy with audio-visual feedback on the swallowing and the emotional state of persons with a swallowing disorder after a brainstem stroke.Methods:Fifty brainstem stroke survivors with dysphagia were randomly divided into a control group and a combination group, each of 25. In addition to routine swallowing function training, the control group received additional direct feeding training, while the combination group was provided with vibroacoustic feeding training and swallowing stimulation from an animated audio-visual presentation. Before and after the treatment, the subjects′ swallowing function was quantified using the Standard Swallowing Assessment (SSA) scale and the Gugging swallowing screen (GUSS). The Positive and Negative Emotions Scale (PNAS) was used to quantify their emotional state.Results:After the treatment the average SSA scores of both groups had decreased significantly, while the average GUSS and PNAS scores had increased significantly. The average improvements in all three measures were significantly greater in the combination group than in the control group.Conclusion:In addition to routine swallowing function training, feeding training applying vibroacoustics and audio-visual stimulation can significantly improve the feeding function and emotional state of brainstem stroke survivors with dysphagia.

Objective:To evaluate the diagnostic performance and clinical significance of SLE-DAS in the disease activity of SLE patients in China.Methods:The clinical data of 134 patients with SLE were collected. The disease activity was evaluated by SLE-DAS, SLEDAI-2000, BILAG-2004 and PGA scoring tools. Pearson test and Spearman test were used to analyze the correlation. The receiver operating characteristic curve (ROC curve) was used to evaluate SLE-DAS, and Kappa consistency test was adapted to assess the consistency of the two scoring methods.Results:One hundred and thirty-four patients with SLE, including 7 males and 127 females, aged 13-77 years, with an average of (35±13) years were included. Among them, renal involvement was 38.1%, skin mucosal involvement was 11.2%, musculoskeletal involvement was 8.2%, blood system involvement was 13.4%, heart and lung involvement was 2.2%, neuropsychiatric involvement was 1.5%, and multisystem involvement was 3.0%. SLE-DAS was positively correlated with CRP, ESR, anti-dsDNA antibody, urinary protein (24 h) level, SLEDAI-2000, BILAG-2004 and PGA ( r=0.25, 0.34, 0.47, 0.77, 0.93, 0.94, 0.95, P<0.01); SLE-DAS was negatively correlated with PLT, Hb, C3 and C4 ( r=-0.29, -0.43, -0.41, -0.32, P<0.01). When SLEDAI-2000>5 was used as a cut point for analyzing SLE-DAS, the results showed that the area under the curve (AUC) 95% CI of SLE-DAS was 0.961 (0.927,0.995), the Yoden index was 0.845. When the cut-off value was set up to 4.65( P<0.001), the sensitivity was 98.11%, the specificity was 86.42%, and the accuracy was 91.04%. Kappa consistency test showed that kappa value was 0.819( P<0.001). Conclusions:SLE-DAS can be used to evaluate the disease activity of SLE patients and can be used as the evidence to guide treatment plan in clinical practice.

In order to improve the disaster response ability of resident physicians under standardized training, this study designed a disaster medicine curriculum of traditional Chinese and Western medicine with reference to domestic and foreign experience. The curriculum consisted of 8 modules with a total of 26 class hours. The definition and classification of disasters and the status of traditional Chinese medicine in disaster medicine were introduced. This study evaluated the teaching effect of disaster medicine curriculum of traditional Chinese and Western medicine carried out by the Emergency Trauma Center of the Seventh People's Hospital Affiliated to Shanghai University of Traditional Chinese Medicine in 84 resident physicians under standardized training. The results showed that the objective test scores of resident physicians under standardized training before and after the course were (45.00±2.51) and (76.25±2.76), respectively ( P<0.001). A questionnaire survey on the subjective understanding of knowledge related to disaster medicine of traditional Chinese and Western medicine was conducted among resident physicians under standardized training before and after the course. The results showed that the test scores before and after the course were (50.88±1.41) and (64.64±1.80), respectively ( P<0.001). This study showed that the theoretical knowledge, skills, and comprehensive ability of resident physicians under standardized training in disaster relief have been greatly improved through the disaster medicine-related curriculum, providing a reference for the establishment of disaster medical education-related curriculum of integrated traditional Chinese and Western medicine.
