Objective:To investigate the uptake patterns of 18F-fluorodeoxy glucose ( 18F-FDG) in the endometrium using positron emission tomography (PET) imaging and to differentiate these from stage IA endometrial cancer. Methods:From September 2022 to April 2024, a prospective inclusion of 354 women without gynecological diseases and no hormone usage who underwent 18F-FDG PET-CT examinations at the affiliated hospital of Qingdao University were set as the physiological group, while a group containing 42 cases of Stage IA endometrial carcinoma was also set. The physiological group was divided into five groups based on the menstrual cycle: menstrual period, proliferative phase, ovulatory phase, secretory phase, and menopausal phase. The images were analyzed using visual and quantitative measurements; quantitative analysis indicators were standardized uptake value maximum (SUVmax) and the region of interest/liver ratio (R/L value). Receiver operating characteristic (ROCs) curve was used to determine the optimal cutoff values for SUVmax and R/L value. A clinical model was established using binary logistic regression, and ROC curves were drawn to evaluate the predictive performance of the model. Results:The uptake of 18F-FDG in the endometrium exhibited cyclical variations throughout different physiological phases, with higher uptakes observed during the menstrual and ovulation phases (SUVmax values of 6.66±3.26 and 3.89±1.21, respectively), which are significantly higher than those in the proliferative phase [median SUVmax of 2.54 (2.02, 3.47)], secretory phase (SUVmax of 2.55±0.86), and menopausal phase [SUVmax median of 2.04 (1.69, 2.29)]. During the menstrual and ovulation phases, the radiotracer accumulation patterns were triangular in 105 cases, oval in 32 cases, and round-like in 2 cases. All 42 cases of endometrial cancer showed 18F-FDG uptake, with radiotracer accumulation patterns being round-like in 17 cases, oval in 10 cases, triangular in 9 cases, and irregular in 6 cases. There were statistically significant differences in the shapes of radiotracer concentration between the menstrual, ovulatory periods, and endometrial carcinoma (both P＜0.001). The SUVmax and R/L values in menstrual period and ovulatory period were significantly lower than that in endometrial carcinoma group ( P＜0.001). During the menstrual phase, the optimal cutoff values for SUVmax and R/L in distinguishing between endometrial and endometrial cancer were 12.59 and 3.81, respectively, with corresponding AUCs of 0.885 and 0.842. After incorporating endometrial uptake morphology into the model, the AUCs was improved to 0.969 and 0.948, respectively. During the ovulatory phase, the optimal cutoff values for SUVmax and R/L were 5.96 and 2.85, respectively, with AUCs of 0.984 and 0.968. After integrating endometrial uptake morphology into the model, the AUCs were increased to 0.999 and 0.998, respectively. Conclusions:The 18F-FDG PET imaging of the endometrium shows higher uptake during the menstrual and ovulatory periods, primarily triangular in shape; endometrial carcinoma uptake is significantly higher than the physiological uptake during the menstrual and ovulatory periods, mainly in circular, oval, and irregular shapes. When SUVmax≥5.96, R/L≥2.85, combined with the physiological cycle of the subjects and the morphological characteristics of the radiotracer concentration, it is possible to effectively differentiate between physiological uptake and Stage IA endometrial carcinoma.

Objectives:To explore the morphological changes of the superficial and deep thoraolumbar paraspinal muscles on both convex and concave sides during rest and contraction states in patients with mod-erate adolescent idiopathic scoliosis(AIS),and their effects on scoliosis angle,to analyze the relations between scoliosis angle and the morphological changes of paraspinal muscles.Methods:21 AIS patients(thoracic Cobb angle 20°-45°,S-shaped with the main curve in thoracic segment,4 males and 17 females,aged 13.9±1.6 years old)treated in our hospital from July 2020 to December 2023 and 21 healthy subjects(7 males and 14 females,aged 14.6±1.4 years old)were prospectively enrolled.The morphological data of thoracolumbar paraspinal muscles were collected with musculoskeletal ultrasound,including the resting thickness and thick-ness during maximum voluntary isometric contraction(MVIC)of superficial erector spinae(ES)and multifidus(MF)muscles of AIS patients on both convex and concave sides(left and right sides of healthy controls).The differences in resting thickness,contraction thickness,change rate of contraction thickness,and total resting thickness and total contraction thickness(ES+MF)of superficial and deep thoracolumbar paravertebral muscles between the two groups were analyzed,and the structural characteristics of the thoracolumbar paravertebral muscles on the convex and concave sides of AIS were analyzed.The correlation between Cobb angle in tho-racolumbar segment and morphological indexes(resting thickness,contraction thickness change rates)of ES and MF muscles was analyzed,and the influence of scoliosis severity on the morphology of superficial and deep paravertebral muscle was further analyzed.Results:In AIS patients,the mean thoracic Cobb angle were 31.62°±7.68°,and mean lumbar Cobb angle were 19.52°±6.48°.Comparing with healthy controls,patients with AIS were significantly different in resting thickness,contraction thickness and thickness change rates of tho-racic paraspinal muscles on both convex and concave sides,and the resting thickness of ES in thoracic seg-ment on concave side was less than that on the convex side,which of MF was less on the convex side than on the concave side(P＜0.01).The contraction thickness of thoracic MF muscles on the convex and concave sides in S-type AIS patients was smaller than that in healthy controls(P＜0.05),while the contraction thickness of thoracic ES muscles on the convex and concave side wasn't statistically different from that of healthy con-trols,and the contraction thickness change rate of ES muscles on the convex and MF on the concave side of thoracic segment in AIS patients was significantly decreased(P＜0.05).There was no significant difference in the total resting thickness of thoracic(convex and concave)paravertebral muscles(ES+MF)between AIS patients and the corresponding segments(left and right)of control group(P＞0.05),and there was no statistically signifi-cant difference in the total resting thickness of thoracic paravertebral muscle between the convex and concave sides of AIS patients(P＞0.05).The total contraction thickness of thoracic paravertebral muscle(ES+MF)in AIS patients was lower than that in control group(P＜0.05).Compared with the control group,the resting thickness,contraction thickness and thickness change rate of lumbar MF muscle on the convex and concave sides in AIS patients were significantly reduced(P＜0.05),and the contraction thickness change rate of the lumbar ES muscle on the concave side was less than that of the control group(P＜0.05).There were no significant differ-ences in resting thickness and contraction thickness between the convex and concave paravertebral muscles in AIS patients(P＞0.05).The total resting thickness(ES+MF)and total contraction thickness(ES+MF)of lumbar(convex and concave)paraspinal muscles in AIS patients were lower than those in control group(P＜0.05).There was a significant negative correlation between the Cobb angle of the main thoracic curve and the rest-ing thickness of the thoracic MF muscle on the concave and the change rate of the contraction thickness of the thoracic ES muscle on the convex in S-type AIS patients(r=-0.53/-0.45,P＜0.05).There was no signifi-cant correlation between the Cobb angle of lumbar segment and the change rates of the resting thickness and contraction thickness of ES and MF muscles on both convex and concave sides(P＞0.05).Conclusions:In pa-tients with moderate S-type AIS,there are different muscle morphological changes in the paraspinal muscles on both convex and concave sides of the main thoracic curve,and the concave paravertebral muscle is more affected by scoliosis;The contraction function of the bilateral deep core stabilizing muscles in the lumbar re-gion is markedly decreased.Different patterns of superficial and deep muscle atrophy and contractility decline may be a key cause of spinal movement disorder and scoliosis progression in AIS patients.

Objective:To detect adverse reaction risk signals of triazole antifungal agents and provide evidences for their safe use in clinic.Methods:Adverse reaction/event reports with fluconazole, itraconazole, voriconazole, posaconazole, or isavuconazonium as the primary suspect drug were collected from the data in National Adverse Drug Reaction Monitoring System of China reported by Shandong Province from January 2004 to June 2024 and the US Food and Drug Administration Adverse Event Reporting System (FAERS) database from the first quarter of 2004 to the second quarter of 2023. Adverse reaction/event terms were standardized using the preferred term (PT) and system organ class in Medical Dictionary for Regulatory Activities 24.0. Risk signals were detected using the reporting odds ratio (ROR) method and the Bayesian confidence propagation neural network (BCPNN) algorithm. A PT was defined as an adverse reaction risk signal if the number of reports was ≥3, the lower limit of the 95% confidence interval ( CI) for ROR was >2, and the lower limit of the 95% CI for the information component ( IC) was >0. Descriptive statistical analysis was performed. Results:A total of 3 988 reports with the above 5 antifungal drugs as the primary suspect drug were collected from data in National Adverse Drug Reaction Monitoring System of China reported by Shandong Province, 822 (20.6%) of which were serious cases. Voriconazole, fluconazole, itraconazole, posaconazole, and isavuconazonium was the primary suspect drug in 1 852, 1 395, 703, 27, and 11 cases among the 3 988 reports, and in 591 (31.9%), 149 (10.7%), 59 (8.4%), 18 (66.7%), and 5 (5/11) serious cases among the 822 serious case reports, respectively. A total of 20 066 reports with the above 5 drugs as the primary suspect drug were collected in FAERS database, 9 635 (48.0%) of which were serious cases. Voriconazole, fluconazole, itraconazole, posaconazole, and isavuconazonium was the primary suspect drug in 7 758, 6 180, 2 869, 1 796, and 1 463 cases among the 20 066 reports, and in 4 295 (55.4%), 2 806 (45.4%), 1 191 (41.5%), 828 (46.1%), and 515 (35.2%) serious cases among the 9 635 serious case reports, respectively. Based on the data reported by Shandong Province and in FAERS database, 18 and 207 risk signals of adverse reaction not mentioned in the labels were identified, respectively, and 5 of them were identified in both databases, including fluconazole-induced renal impairment and voriconazole-induced oliguria, delirium, psychiatric disorders, and rhabdomyolysis. In the data reported by Shandong Province and in FAERS database, 13 and 189 reports of muscle-related disorders (rhabdomyolysis, myopathy, and myositis) were identified respectively, involving voriconazole (in 8 and 62 cases), itraconazole (in 4 and 74 cases), and fluconazole (in 1 and 53 cases).Conclusions:Renal impairment induced by fluconazole and oliguria, delirium, psychiatric disorders, and rhabdomyolysis induced by voriconazole are risk signals of adverse reaction not mentioned in the labels for triazole antifungal agents. Voriconazole, itraconazole, and fluconazole may also cause muscle-related disorders, warranting vigilance in clinical practice.

Pancreatic duct stents are essential devices for managing chronic pancreatitis,ductal strictures,and postoperative fistula.Conventional plastic and metal stents effectively facilitate pancreatic drainage but often cause infection,restenosis,or migration upon long-term implantation.An ideal stent should provide excellent biocompatibility,efficient drainage,and controllable biodegradation.With advances in material science and medical-engineering integration,stent technology has evolved from inert implantation to intelligent degradation.Biodegradable polymers and metals,particularly magnesium alloys(Mg-Zn-Mn),offer tunable mechanical strength,corrosion resistance,and in vivo degradability.Mg-2Zn-1.0Mn alloy achieves balanced strength and corrosion control through compositional optimization and surface modification.Polymeric stents such as polylactic acid and polydioxanone demonstrate favorable drainage and avoid secondary removal.Composite biodegradable stents,exemplified by the multi-rate ARCHIMEDES model,have received international approval.Supported by 3D printing and smart functionalization-such as drug-eluting or shape-memory designs-next-generation pancreatic stents may achieve integrated functions of support,repair,and tumor inhibition.Future research should emphasize interdisciplinary material design,degradation kinetics under physiological conditions,and long-term biocompatibility to accelerate clinical translation.

Objective To explore the influencing factors of immune-associated thyroid dysfunction caused by sintilimab treatment in solid tumors and construct a prediction model.Methods Medical records of patients diagnosed with solid tumors and treated with sintilimab at Peking University People's Hospital(Xizhimen Campus,Tongzhou Campus,Shijiazhuang Campus)from January 2023 to September 2024 were collected to explore the influencing factors that caused immune-related thyroid dysfunction using univariate and multifactorial binary logistic regression analyses and to establish a prediction model.The predictive effect of the model was assessed using the receiver operating characteristic(ROC)curve.Results A total of 120 patients were included,and 33 presented with immune-related thyroid dysfunction.Multifactorial logistic regression analysis revealed that thyroid-stimulating hormone(TSH)[OR=2.470,95%CI=(1.279,4.771)]and treatment cycles[OR=1.298,95%CI=(1.117,1.509)]were independent risk factors for the occurrence of immune-associated thyroid dysfunction,and the difference was statistically significant(P＜0.05).The area under the ROC curve was(0.897±0.043)[95%CI=(0.813,0.981)],the Yoden index was 0.703,and the model prediction accuracy was 86.5%.Conclusion The risk of immune-related thyroid dysfunction caused by sintilimab is high,and TSH and treatment cycle are the influencing factors,and the constructed model has certain predictive value and is of reference significance.
