Autoimmune pancreatitis is a special type of chronic pancreatitis that can lead to abnormal pancreatic exocrine function in patients. Autoimmune pancreatitis comorbid with pancreatic exocrine insufficiency has a complex pathogenesis， and there is limited research on this topic， leading to the lack of understanding of such patients in clinical practice. This article introduces the epidemiology of autoimmune pancreatitis， briefly describes the pathogenesis of pancreatic exocrine insufficiency caused by autoimmune pancreatitis， and summarizes the various detection methods for pancreatic exocrine function， nutritional assessments， lifestyle management， and drug therapy， in order to strengthen the understanding of autoimmune pancreatitis comorbid with pancreatic exocrine insufficiency and improve the clinical diagnosis and treatment of pancreatic exocrine insufficiency.

BACKGROUND:Although researchers have noted that fibroblast growth factor receptor 1 shows great potential in rheumatoid arthritis bone destruction,there is a lack of reviews related to the potential mechanisms of fibroblast growth factor receptor 1 in rheumatoid arthritis bone destruction. OBJECTIVE:To comprehensively analyze the mechanism of fibroblast growth factor receptor 1 in bone destruction in rheumatoid arthritis by reviewing the relevant literature at both home and abroad. METHODS:We searched the CNKI database using the Chinese search terms"fibroblast growth factor receptor 1,rheumatoid arthritis,bone destruction,bone cells,osteoblasts,osteoclasts,chondrocytes,macrophages,synovial fibroblasts,T cells,vascular endothelial cells."PubMed database was searched using the English search terms"fibroblast growth factor receptor 1,rheumatoid arthritis,bone destruction,osteocytes,osteoblasts,osteoclasts,chondrocytes,macrophages,synovial fibroblasts,T cells,endothelial cells."The search period focused on April 1992 to January 2024.After screening the literature by reading titles,abstracts,and full texts,a total of 82 articles were finally included for review according to inclusion and exclusion criteria. RESULTS AND CONCLUSION:Fibroblast growth factor receptor 1 was found to be widely expressed in bone tissue-associated cells,including osteoblasts,osteoclasts,and osteoclasts.Fibroblast growth factor receptor 1 affects bone remodeling and homeostasis by regulating the function of these cells,as well as promoting the onset and progression of bone destruction in rheumatoid arthritis.Fibroblast growth factor receptor 1 is involved in the inflammatory response of synovial fibroblasts and macrophages and regulates angiogenesis of endothelial cells in synovial tissues.Fibroblast growth factor receptor 1 promotes bone destruction in several ways.Fibroblast growth factor receptor 1 may be a potential causative agent of bone destruction in rheumatoid arthritis and provides a reference for further research on its therapeutic targets.

Objective To propose a whole-life cycle management model for valvular heart disease (VHD), systematically elucidate its underlying logic and implementation pathways, and concurrently review and analyze its preliminary application outcomes. Methods Since 2020, West China Hospital of Sichuan University has established a management system encompassing "assessment-decision-intervention-follow-up", including: (1) a risk-stratified, tiered management pathway; (2) six core functions ("promotion, screening, prevention, diagnosis, treatment, and rehabilitation") coordinated by disease-specific managers; (3) an intelligent decision support information platform; and (4) a collaborative network of multidisciplinary teams and regional academic alliances. To evaluate the effectiveness of this management model, we retrospectively included three cohorts: (1) the population screened by echocardiography from 2020 to 2024, analyzing the detection rate of aortic valve disease and risk stratification; (2) patients enrolled in the whole-life cycle management from April 2021 to December 2024, assessing follow-up outcomes, hospital satisfaction, and changes in quality of life; (3) patients who underwent transcatheter aortic valve replacement (TAVR) from January 2022 to January 2024, evaluating the one-year all-cause mortality rate, perioperative complications, and improvements in New York Heart Association (NYHA) classification. Results Between 2020 and 2024, a total of 583 874 individuals underwent echocardiographic screening. A total of 48 089 patients with aortic valve disease were identified, including 3 401 (7.1%) high-risk patients, 18 657 (38.8%) moderate-risk patients, and 26 031 (54.1%) low-risk patients. Among them, 2 417 patients were enrolled in whole-life cycle management. Patient satisfaction scores showed a yearly increase, rising from 73.89 points before 2020 to 93.74 points in 2024. The 1-year mortality rate in the TAVR cohort decreased to 5.3%, significantly lower than the 8.2% observed under early standard management between 2014 and 2019 (P<0.01). Conclusion Through process optimization and resource integration, the VHD whole-life cycle management model has demonstrated significant effectiveness in standardizing diagnostic and follow-up procedures, enhancing patient satisfaction and quality of life, and reducing mortality. These outcomes highlight its practical value for broader implementation in China.

Objective:To investigate the clinical efficacy of 3D printed metal augment or tibial prosthesis for reconstruction of large bone defects in total knee arthroplasty (TKA) and knee revision surgery.Methods:A total of 7 patients (7 knees) with TKA or knee revision who were admitted to the Department of Orthopaedics of the Second Affiliated Hospital of Zhejiang University School of Medicine with large bone defects from July 2018 to December 2023 were retrospectively analyzed, including 4 patients with TKA and 3 patients with knee revision. There were 3 males and 4 females, aged 58.7±7.6 years (range, 54-68 years), 3 patients with left knee and 4 patients with right knee. All the patients had bone defects in the knee joint (AORI type III), 2 cases had bone defects only in the femur, 4 cases had bone defects only in the tibia, and 1 case had bone defects in both the tibia and femur, which were treated with personalized reconstruction using 3D printing. Hip-knee-ankle angles, American Knee Society score (KSS) before and after surgery were compared, and postoperative complications were observed.Results:All patients successfully completed the operation, and the operation time was 189.3±35.5 min (range, 125-240 min). Complex TKA was performed in 4 cases with surgical times of 175, 195, 210, and 240 min, and revision surgery was performed in 3 cases with surgical times of 125, 180, and 200 min, respectively. Intraoperative blood loss was 114±24.4 ml (range, 100-150 ml). Five cases used 3D printed metal augment, and two used 3D printed one-piece tibial components. All patients were followed up for 2, 2, 5, 6, 7, 20, 57 months, respectively. The KSS of the five patients at 3 months postoperatively were 56, 61, 66, 56, and 56 points, respectively, greater than the preoperative scores of 35, 44, 36, 27, and 41 points. The KSS functional scores of the five patients at 3 months postoperatively were 45, 45, 45, 30, and 45 points, respectively, which were greater than the preoperative scores of 30, 30, 15, 20, and 20 points. The hip-knee-ankle angle was 181.8°±3.4° (range, 177.9° to 188.0°) at the final follow-up and 175.8°±12.4° (range, 153.3° to 192.1°) before surgery, with no significant difference ( t=-1.230, P=0.242). At the final follow-up, the 3D printed component was well integrated with the bone surface, the prosthesis was securely positioned, and the force lines of the lower limbs were normal. There were no postoperative complications such as poor wound healing, infection, fat liquefaction, nerve injury, deep vein thrombosis of lower limbs, knee joint stiffness, periprosthesis infection and loosening. Conclusion:Using 3D printed metal augment or tibial prosthesis to reconstruct the huge bone defect in TKA and revision has a satisfactory early clinical effect, satisfactory joint function and good surgical safety.

AIM To investigate the effects of Ginkgo biloba extract on hearing function,cochlear morphology and autophagy-related protein expression in a rat model of presbycusis.METHODS Forty-five rats were randomly divided into the control group,the model group and the low,medium and high dose G.biloba extract groups(10,20 and 30 mg/kg),with 9 rats in each group.The rat model of presbycusis was established by intraperitoneal injection of 500 mg/kg D-galactose(D-gal).Eight weeks after the corresponding administration,the rats had their changes of hearing threshold detected by the auditory brainstem evoked potential(ABR);their morphological changes of cochlear hair cells,stria vascularis(SV)and spiral ganglion cells observed by HE staining;their number of hair cells inside and outside the cochlea detected by immunofluorescence staining;their ultrastructure changes of cochlear hair cells observed by transmission electron microscopy;and their expression of autophagy-related proteins in cochlea tissue detected by Western blot.RESULTS Compared with the control group,the model group displayed increased ABR threshold(P<0.01);more severely damaged inner and outer hair cells,spiral ganglion cells and SV,decreased SV thickness and numbers of spiral ganglion cells,inner and outer hair cells and autophagosomes(P<0.01);decreased protein expressions of Beclin1 and LC3 Ⅱ and ratio of LC3 Ⅱ/LC3 Ⅰ in cochlear tissue(P<0.01),and higher P62 protein expression(P<0.01).Compared with the model group,the medium and high dose G.biloba extract groups shared decreased ABR thresholds(P<0.01);improved morphology of inner and outer hair cells and SV in the cochlea,normalized,morphology of spiral ganglion cells,and increased SV thickness and the numbers of spiral ganglion cells,inner and outer hair cells and autophagosomes(P<0.05,P<0.01);increased protein expressions of Beclin1 and LC3 Ⅱ and the ratio of LC3 Ⅱ/LC3 Ⅰ in the cochlea(P<0.01),and decreased P62 protein expression(P<0.01).CONCLUSION The protective effects G.biloba extract on hearing function and cochlear cells in the rat model of presbycusis may be associated with the up-regulated expression of Beclin1 and LC3 Ⅱ proteins and down-regulated P62 protein expression in cochlear tissues.

ObjectiveTo understand the mortality trends among residents of Fuling District， Chongqing， before and after theCOVID-19 outbreak， and to provide references for the government to formulate disease prevention and control policies and measures. MethodsData on mortality and population in Fuling District from 2017 to 2022 were collected to analyze population mortality and standardized mortality rates， and to compare the changes in the causes of death by year and before and after the pandemic. ResultsFrom 2017 to 2022， the crude mortality rate in Fuling District showed an upward trend （APC=3.04%， P<0.05）， while the standardized mortality rate showed a downward trend （APC=-6.47%， P<0.01）. The mortality rate of males was higher than that of females （P<0.05）， with different age groups having different causes of death composition. The highest proportion of deaths in 0-year-old group was from infectious diseases， maternal and neonatal diseases， and nutritional deficiencies， the highest proportion of deaths in the 1‒24 age group， with the exception of those aged 5‒9， was from injuries， and the main cause of death for residents aged 25 and above was chronic diseases. The mortality rate of mental and behavioral disorders rose from the 13th to the 9th place. According to the epidemic situation of COVID-19， there were no changes in the top five causes of death among the entire population. The motility rate of endocrine， nutritional and metabolic diseases rose from the sixth to the fifth place in male population， and the motility rate of malignant tumor rose from the 3rd to the 2nd place in female population. ConclusionThere are no changes in the top five causes of death among the entire population of Fuling District before and after the COVID-19 outbreak. Chronic diseases remain the main cause of death. It is necessary to control the risk factors for cardiovascular and cerebrovascular diseases such as hypertension， diabetes， and dyslipidemia， and to curb the rising trend of mortality rates from strokes and acute myocardial infarction. For deaths caused by accidental injuries， targeted health education should be conducted for different populations.

Objective To evaluate the methodological and reporting quality of published guidelines/consensus for childhood autism(CA),providing a basis for formulating domestic CA guidelines.Methods We searched databases including CNKI,Wanfang Data,SinoMed,Medlive,PubMed,national institute of health and clinical excellence(NICE),national guideline clearinghouse(NGC),and Scottish intercollegiate guidelines network(SIGN)for Chinese and foreign guideline/consensus on childhood autism published before February 1,2024.Two researchers independently evaluated the methodology and reporting quality of the guideline/consensus using the Appraisal of Guidelines Research and Evaluation Ⅱ(AGREE Ⅱ)and Reporting Items for Practice Guidelines in Healthcare(RIGHT)tools.Results After literature screening,19 CA guidelines/consensus were included,comprising 11 guidelines,7 consensus,and 1 expert recommendation,with 9 domestic and 10 foreign articles.The AGREE Ⅱ evaluation scores for the six domains were as follows:scope and purpose(91.1％±4.5％),stakeholder involvement(86.8％±6.7％),rigour of development(83.0％±10.2％),clarity of presentation(84.3％±6.2％),applicability(82.7％±13.3％),and editorial independence(65.4％±21.8％).The RIGHT checklist reported rates for the seven domains were:basic information(87.6％±11.0％),background(87.6％±13.8％),evidence(81.1％±22.6％),recommendation(71.1％±38.4％),review and quality assurance(83.5％±16.7％),funding and declaration and management of interests(48.7％±29.4％),and other information(64.4％±11.8％).The domain with the lowest score for methodological quality was"editorial independence"and for reporting quality,it was"funding and declaration and management of interests".The reporting rate of domestic articles(26.2％±1.5％)was significantly lower than that of foreign articles(52.6％±2.2％),with a statistically significant difference(P<0.05).Conclusion The overall quality of current childhood autism guidelines/consensus requires improvement.During the formulation and reporting of guidelines/consensus,strictly adhering to AGREE Ⅱ and RIGHT is imperative,and it is essential to clearly report funding sources and conflicts of interest.

Objective To clone the full-length sequence,subcellular localization,and analyze the expression patterns of the β-caryophyllene synthase gene(AaCPS)of Artemisia argyi,in order to lay a foundation for the gene function analysis of sesquiterpene biosynthesis pathway in A.argyi.Methods The genes annotated as CPS were selected from the transcriptome data of A.argyi.The full-length cDNA sequence of the target gene was obtained by PCR,and the coding region was analyzed using bioinformatics.A prokaryotic expression vector was constructed and transformed into Escherichia coli competent cells to express recombinant protein.A green fluorescent protein(GFP)fused expression vector was constructed,and the subcellular localization of AaCPS was observed using Agrobacterium tumefaciens transient expression method in tobacco.Real-time quantitative PCR(qRT-PCR)was used to analyze the expression patterns of the AaCPS at different harvest times(April,May,June,July).Determination of β-caryophyllene by HS-SPME-GC-MS and correlation analysis.Results The AaCPS gene was cloned from A.argyi.The full-length open reading frame(ORF)was 1647 bp,encoding 548 amino acids.The molecular weight was 63 667 Da with a theoretical pI of 5.94.AaCPS contained conserved Terpen_synth and Terpen_synth_C domains.Phylogenetic analysis indicated that AaCPS was closely related to the CPS protein of Artemisia annua.SDS-PAGE showed the presence of target protein bands between 75 000-120 000 Da(containing 28 132 Da of the labeled protein),indicating successful expression of the AaCPS protein.The protein was found to be localized in the cytoplasm.As shown by qRT-PCR,the expression of AaCPS gene showed an upward trend,reaching the highest in July.The results of HS-SPME-GC-MS showed that the content of β-caryophyllene increased gradually from April to the highest in June.It is consistent with the trend of AaCPS gene expression from April to June.Conclusion Through the cloning and analysis of AaCPS gene,a foundation has been laid for further study of the functional identification of the AaCPS gene in the sesquiterpenes biosynthesis pathway in A.argyi.

Objective:To investigate the impact of ionizing radiation(IR)on the structure and function of the testis and pro-vide some strategies for the prevention and treatment of IR-induced damage(IRD).Methods:Using radiation dose simulation,se-men analysis,hormone testing,electron microscopy and single-cell transcriptome sequencing,we assessed and analyzed a case of IRD.We established a mouse model of IRD to validate the results of single-cell sequencing,and investigated the specific biological mecha-nisms of IRD and potential strategies for its intervention.Results:IR at 1-2 Gy significantly reduced sperm concentration and mo-tility,which gradually recovered after 12 months but the percentage of morphologically normal sperm remained low.It also caused im-balanced levels of various steroid hormones,decreased testosterone and dehydroepiandrosterone sulfate,increased progesterone,prolac-tin,luteinizing hormone,and follicle-stimulating hormone.Electron microscopy revealed damages to the testis structure,including loss of germ cells,atrophy of the seminiferous tubules,nuclear membrane depression of the spermatocytes,mitochondrial atrophy and de-formation,and reduction of mitochondrial cristae.Single-cell sequencing indicated significant changes in the function of the Leydig cells and macrophages and disrupted lipid-related metabolic pathways after IRD.Administration of L-carnitine to the mouse model im-proved lipid metabolism disorders and partially alleviated IRD to the germ cells.Conclusion:Ionizing radiation can cause disorders of testicular spermatogenesis and sexual hormones and inhibit lipid metabolism pathways in Leydig cells and macrophages.Improving lipid metabolism can alleviate IRD to germ cells.
