Immunoglobulin G4-related disease (IgG4-RD) is a rare systemic immune-mediated disorder characterized by infiltration of IgG4-positive plasma cells and multiorgan fibrosis. Among them, cases with multiple pancreatic cystic lesions as the prominent manifestation are relatively rare, and they are easily misdiagnosed as pancreatic tumors or pancreatitis in clinical practice. Herein, we report one patient with IgG4-RD admitted to Peking Union Medical College Hospital. The patient initially presented with multiple pancreatic cystic lesions and aneurysmal dilatation of the abdominal aorta, accompanied by markedly elevated serum IgG4 levels. Combined with pathological findings from submandibular gland biopsy, the diagnosis of IgG4-RD was ultimately established. After treatment with a regimen of glucocorticoids combined with cyclophosphamide, the patient′s condition improved. Meanwhile, we performed a literature review of cases with IgG4-RD-related pancreatic cystic lesions, aiming to improve clinicians′ understanding of this rare disease phenotype.

ObjectiveThis paper used the AGREE Ⅱ guideline evaluation tool to evaluate the quality of 14 clinical guidelines for acute myocardial infarction，aiming to provide reference for the formulation and improvement of the guidelines. MethodsClinical guidelines and expert consensus related to acute myocardial infarction were searched by web search. The search period ranges from January 1，2019 to November 1，2024 in CNKI，VIP，Wanfang Data，SinoMed，Web of Science，OVID， the International Guidelines Collaboration Network （GIN），the UK National Institute for Health and Clinical Excellence （NICE），Yimaitong， and other platforms. Three researchers independently screened the literature and used AGREE Ⅱ to score the screening results. After ensuring that the researchers have a consistent understanding of each guideline，the quality of the guidelines was evaluated. After that，the ratings were analyzed by layer according to the issuing agency，category，method of formulation，and funding situation and compared longitudinally by rating time. The clinical guidelines and expert consensus were compared in terms of content and evidence. ResultsA total of 14 guidelines and consensus were included. The results of AGREE Ⅱ in the six areas in descending order were scope and purpose （62.82%±10.43%），rigor （62.40%±12.77%），editorial independence （62.11%±22.26%），participants （61.42%±11.65%），clarity of expression （59.98%±9.62%），and application （52.94%±16.90%） . Eleven of the guidelines were at level B， and three were at level A. In the stratified analysis，the score of the guideline formulated by the Chinese Medical Doctor Association was lower. There was little difference between the scores of Chinese/Western and Western medicine guidelines. The average score of the guidelines was higher than the consensus. Funded guidelines and consensus scores were higher. In the longitudinal comparison，the highest number of guidelines were developed in 2020 and 2021，while those developed in 2023 scored the highest. In the differential comparison analysis，the content of the guidelines was more comprehensive， and the evidence level was higher，while the content of the consensus was more novel， and the evidence was less. ConclusionThe AGREE Ⅱ score of the clinical guidelines for acute myocardial infarction is generally moderate，and there is room for improvement in terms of applicability. At the same time，the content quality of expert consensus should be improved，and more efforts should be made to develop and apply Chinese medicine guidelines for complications such as heart failure and microcirculatory obstruction after acute myocardial infarction.

Objective:To investigate the efficacy of endoscopic sclerotherapy for internal hemorrhoids and its effects on patients' bowel function.Methods:A total of 111 patients who received endoscopic sclerotherapy at Xi'an No. 3 Hospital from September 2019 to August 2020 were retrospectively included in this study. Clinical efficacy, postoperative complications, perianal discomfort, and abnormal defecation were compared among patients with grade Ⅰ, Ⅱ, and Ⅲ internal hemorrhoids at 1, 4, 8, 12 weeks, and 6 months after surgery.Results:After 6 months of follow-up, the overall response rate was 77.48% (86/111), and the cure rate was 77.17% (79/111). The response rate and cure rate for rectal bleeding were 83.75% (67/80) and 80.00% (64/80), respectively. The response rate and cure rate for prolapse were 82.46% (47/57) and 75.44% (43/57), respectively. There were no statistically significant differences in the response rates and cure rates for rectal bleeding and prolapse symptoms among patients with grade Ⅰ, Ⅱ, and Ⅲ internal hemorrhoids at each follow-up time point (all P>0.05). Among the 111 patients, 27.93% (31/111) experienced perianal discomfort, and 40.54% (45/111) reported abnormal defecation. The incidences of perianal discomfort and abnormal defecation were not statistically significant among patients with grade Ⅰ, Ⅱ, and Ⅲ internal hemorrhoids (both P>0.05). In patients with gradeⅠ and Ⅱ internal hemorrhoids, perianal discomfort symptoms began to improve 4 weeks after surgery, while symptoms of abnormal defecation started to improve 1 week after surgery. Conclusions:Endoscopic sclerotherapy has a good clinical efficacy for rectal bleeding and prolapse symptoms in patients with grade Ⅰ, Ⅱ, and Ⅲ internal hemorrhoids. Additionally, it improves perianal discomfort and abnormal defecation by identifying the anal canal transition zone in patients with internal hemorrhoids.

Objective:To apply the Timed Up and Go Test(TUGT)to investigate the correlation between motor function, emotional state, cognitive function, and sleep quality among elderly individuals in the Chinese community.Methods:A cross-sectional study was conducted, involving 739 subjects aged 60 to 90 years, who were randomly recruited from December 2021 to August 2023 across Beijing, Tianjin, Zhejiang, Guangdong, and Hainan Provinces in China.Basic demographic information was collected, and the TUGT was utilized to assess motor function.Based on the TUGT time(t), the subjects were divided into three groups: normal motor function group, mild motor abnormality group, and significant motor abnormality group.Cognitive function was evaluated using the Chinese Revised Mini-Mental State Examination(MMSE), while the Patient Health Questionnaire Depression Scale(PHQ-9)was employed to measure the degree of depression.Additionally, the Epworth Sleepiness Scale(ESS)was used to assess excessive daytime sleepiness.The correlation between subjects' motor function and their cognitive abilities, mood, and sleep was subsequently analyzed.Results:Systolic blood pressure, heart rate, PHQ-9, MMSE, and ESS scores were identified as significant factors influencing TUGT time.Specifically, TUGT time was positively correlated with PHQ-9 and ESS scores, while exhibiting negative correlations with systolic blood pressure, heart rate, and MMSE scores.Additionally, TUGT time was negatively correlated with the MMSE subcomponents of orientation, immediate memory, and verbal ability.All observed differences were statistically significant(all P<0.05).Logistic regression analysis indicated that an increase in the PHQ-9 score was associated with an odds ratio( OR)of 1.099(95% CI: 1.045-1.155, P<0.001)(mild motor abnormality group)and 1.150(95% CI: 1.066-1.242, P<0.001)(Significant motor abnormality group).Additionally, a reduction in the MMSE score was observed, with an OR of 0.939(95% CI: 0.886-0.995, P<0.001)(mild motor abnormality group)and 0.793(95% CI: 0.729-0.862, P<0.001)(Significant motor abnormality group).Furthermore, an increase in the ESS score was noted, with ORs of 1.139(95% CI: 1.094-1.186, P<0.001)(mild motor abnormality group)and 1.203(95% CI: 1.132-1.279, P<0.001)(Significant motor abnormality group).These findings suggest that these variables are independently related to decreased motor function. Conclusions:Depression, cognitive impairment, and excessive daytime sleepiness are independent risk factors for motor dysfunction among elderly individuals in community settings.The Timed Up and Go Test TUGT can be utilized for the early screening of motor function decline in this population.

Objective:To analyze the factors influencing postoperative complications and survival in patients undergoing hepatectomy for primary liver cancer (PLC).Methods:Two hundred and eighty-eight patients with PLC who underwent hepatectomy at Tianjin Medical University Cancer Hospital from April 2018 to December 2020 were prospectively enrolled, including 235 males and 53 females, aged (58.5±9.5) years. Nutritional evaluations included the nutritional risk screening 2002 (NRS-2002), patient-generated subjective global assessment (PG-SGA), and physical metrics such as body mass index, handgrip strength, arm circumference, mid-arm muscle circumference (MAMC), and triceps skinfold thickness (TSF). Based on the occurrence of postoperative complications during hospitalization including abdominal infection, bleeding, bile leakage, intra-abdominal fluid accumulation, pulmonary infection, intestinal fistula, and wound dehiscence, patients were divided into two groups: the complication group ( n=205) and the non-complication group ( n=83). Multivariate logistic regression analysis was performed to identify the factors related to postoperative complications, while Cox proportional hazards regression was used to evaluate the impact of various variables on postoperative survival. Survival analysis was conducted using the Kaplan-Meier method, and differences in survival rates were compared using the log-rank test. Results:Compared with the non-complication group, patients in the complication group had a significantly longer postoperative hospital stay [13(8, 16) d vs. 7(5, 9) d], higher proportions of low MAMC [34.1% (24/83) vs. 20.0% (41/205)], lower grip strength [28.9% (24/83) vs. 17.6% (36/205)], higher incidence of intraoperative blood loss ≥200 ml [44.6% (37/83) vs. 22.0% (45/205)], and greater proportion of resection involving ≥3 liver segments [45.8% (38/83) vs. 26.3% (54/205)] (all P<0.05). Multivariate logistic regression analysis identified the low MAMC ( OR=2.01, 95% CI: 1.09-3.71, P=0.025), intraoperative blood loss ≥200 ml ( OR=2.75, 95% CI: 1.55-4.90, P=0.001), and resection involving ≥3 liver segments ( OR=2.02, 95% CI: 1.15-3.55, P=0.015) as independent risk factors for postoperative complications in patients undergoing hepatectomy for PLC. Multivariate Cox regression analysis revealed that low TSF ( HR=1.94, 95% CI: 1.01-3.72, P=0.047), low handgrip strength ( HR=2.23, 95% CI: 1.29-3.88, P=0.004), and resection involving ≥3 liver segments ( HR=1.96, 95% CI: 1.15-3.36, P=0.014) were risk factors associated with poor survival after surgery. Conclusions:Low MAMC, intraoperative blood loss ≥200 ml, and resection involving ≥3 liver segments are risk factors for postoperative complications in patients undergoing hepatectomy for PLC, while low TSF, reduced handgrip strength, and resection involving ≥3 liver segments are predictors of poor postoperative survival.

BACKGROUND:A novel aggregation induced luminescence fluorescence probe based on the mechanism of intramolecular motility restriction can be used for the detection of disease markers,tumor diagnosis,and bacterial imaging recognition.OBJECTIVE:To prepare a near-infrared Ⅱ nanoprobe called FA-DSPE-PEG-AIE@NPs based on aggregation-induced luminescence,and to explore its potential of targeted fluorescence imaging and photothermal therapy for prostate cancer.METHODS:Lecithin,polyethylene glycol phospholipids,folate polyethylene glycol phospholipids,and aggregation induced luminescent molecule 2TT-oC26B were used as raw materials.The folate-targeted nanoprobe FA-DSPE-PEG-AIE@NPs were prepared by nanoprecipitation method,and basic characterization of the nanoprobe was detected.PC3 human prostate cancer cells and human umbilical vein endothelial cells were selected as experimental objects.The cytotoxicity and phototoxicity of FA-DSPE-PEG-AIE@NPs were detected.PC3 human prostate cancer cells were selected as the experimental objects.Flow cytometry and calcein/propidium iodide staining were used to assess the efficacy of photothermal therapy.PC3 human prostate cancer cells were injected subcutaneously into the abdomen of BALB/C nude mice to establish a tumor model,and nanoprobes FA-DSPE-PEG-AIE@NPs were injected into the tail vein.The mice were immediately subjected to near-infraced Ⅱ fluorescence imaging.12 hours later,the tumor was irradiated by laser for 5 minutes,and the photothermal treatment effect was observed within 14 days.RESULTS AND CONCLUSION:(1)The nanoprobes FA-DSPE-PEG-AIE@NPs with a mean diameter of(171.0±0.3)nm showed a well-defined spherical morphology.The nanoprobe had a wide absorption spectrum and tail emission extending to the near-infrared Ⅱ which emitted a bright near-infrared Ⅱ fluorescence signal under laser irradiation.(2)The nanoprobes FA-DSPE-PEG-AIE@NPs had low cytotoxicity and high phototoxicity.The results of flow cytometry and calcein/propidium iodide staining showed that nanoprobes FA-DSPE-PEG-AIE@NPs had an obvious photothermal killing effect on human prostate cancer cells.(3)The nanoprobes FA-DSPE-PEG-AIE@NPs successfully achieved near-infrared Ⅱ fluorescence imaging of mouse blood vessels and the maximum enrichment time of the tumor was 12 hours.The vessel widths of the hind leg and single blood vessels of abdomen were estimated to be 0.63 mm and 0.42 mm.The tumor volume of mice was significantly smaller after 14 days of treatment.(4)The results show that nanoprobes FA-DSPE-PEG-AIE@NPs can achieve near-infrared Ⅱ fluorescence imaging and photothermal therapy of prostate cancer effectively,which may provide a new method for early diagnosis and combined treatment of prostate cancer.

Objective To compare the efficacy,acceptability and safety of a low-volume magnisium sodicum potassium sulfate oral sulfate solution(OSS)with polyethylene glycol(PEG)electrolytes powder in bowel preparation for colonoscopy.Methods A prospective,single-blinded and single-center cohort study was conducted.The ambulatory and hospitalized 1 037 patients who underwent colonoscopy from April 2023 to January 2024 were enrolled.Participants were divided into OSS group(639 cases)and PEG group(398 cases),according to the bowel cleansing drugs taken orally.After propensity score matching(PSM),each group included 385 cases.The success rate of bowel preparation,scores of Boston bowel preparation scale(BBPS),medication taste,patients'satisfaction and the occurrence of adverse events were compared.Results The success rate of bowel preparation in the OSS group was 96.4％(371/385),higher than the 91.7％(353/385)in the PEG group,and the difference was statistically significant(P＜0.05).The total and segmented BBPS scores of the OSS group were higher than those of the PEG group,the differences were statistically significant(P＜0.05).The medication taste and patients satisfaction of the OSS group were significantly better than those of the PEG group,the differences were statistically significant(P＜0.05).There was no statistically significant difference in incidence of adverse reactions between the two groups(P=0.800).Conclusion Compared to PEG,OSS has a better intestinal cleaning effect,medication taste,and patients satisfaction.In addition,OSS has security that is not inferior to PEG.

Objective To explore the correlation between triglyceride-glucose(TyG)index and hyperuricemia in men with normal fasting blood glucose(FPG)levels.Methods A total of 309 men with normal FPG who participated in a health examination at the Ninth Medical Center of the People's Liberation Army General Hospital in April 2024 were enrolled in this study.All the subjects were divided into the normal uric acid(NUA,n=218)group and the hyperuricemia(HUA,n=91)group according to serum uric acid(SUA)levels.Results Scr,TG,weight,SBP,DBP,BMI,ALT,AST,γ-GGT,and TyG index were higher in the HUA group than in the NUA group(P<0.05).Pearson and Spearman correlation analysis showed that SUA were positively correlated with Scr,eGFR,TG,weight,SBP,DBP,BMI,ALT,AST,γ-GGT and TyG(P<0.05),and negatively correlated with HDL-C(P<0.05).Logistic regression analysis showed that after adjusting for confounding factors,TyG index remained an important influencing factor for HUA.ROC curve analysis showed that the area under the ROC curve of TyG index predicting hyperuricemia in men with normal FPG was 0.665,with an cutoff value of 8.45.Conclusions TyG index in men with normal FPG are influencing factors for hyperuricemia,indicating that hyperuricemia has a close association with insulin resistance,and is an important component of metabolic syndrome.
