Objective:To explore the value of the vesical imaging-reporting and data system (VI-RADS) score based on multiparametric MRI (mpMRI) combined with quantitative tumor MRI parameters in assessing the muscle invasion of bladder cancer.Methods:The study was a case-control study. The data of 87 bladder cancer patients confirmed by pathology who underwent mpMRI of the bladder were retrospectively collected from the First Medical Center of Chinese PLA General Hospital between January 2019 and April 2023 The pathological findings were used as the gold standard to categorize them into the muscle invasive bladder cancer (MIBC) group (29 cases) and non-muscle invasive bladder cancer (NMIBC) group (58 cases). Quantitative parameters were measured based on preoperative mpMRI images, including the length of tumor bladder wall contact, the perpendicular distance between the bladder tumor and the tangent of the bladder wall, the maximal diameter of the bladder tumor, and the volume of the bladder tumor. Bladder cancer was classified according to the VI-RADS scoring criteria. The Mann-Whitney U test was used for intergroup comparisons. Multivariate logistic regression analysis was performed to obtain the independent risk factors related to muscle invasion of bladder cancer and to establish the model. The receiver operating characteristic curves were analyzed for MRI quantitative parameters and logistic regression models, and area under the curve (AUC) comparisons were performed using the DeLong test. Results:The differences in tumor bladder wall contact length, perpendicular distance from the tumor to the tangent line of the bladder wall, maximum diameter, bladder tumor volume, and the VI-RADS scores were statistically significant between the MIBC group and the NMIBC group ( P<0.05). Multifactorial logistic regression analysis showed that tumor bladder wall contact length ( OR=21.07, 95% CI 3.56-124.89, P=0.001) and VI-RADS score ( OR=11.90, 95% CI 3.53-40.12, P<0.001) were the independent risk factors for evaluating the muscle invasion of bladder cancer. The difference between the VI-RADS score and the tumor bladder wall contact length for assessing muscular infiltration of bladder cancer had AUCs of 0.802 (95% CI 0.704-0.899) and 0.759 (95% CI 0.652-0.865). The combined model of VI-RADS score combined with tumor bladder wall contact length had an AUC of 0.891 (95% CI 0.812-0.970), which was higher than the diagnostic efficacy of applying tumor bladder wall contact length or VI-RADS score alone ( Z=3.05, 2.37, P=0.002, 0.018). Conclusion:Tumor contact length with the bladder wall is an independent risk factor for assessing muscle invasion of bladder cancer and the combination of VI-RADS score may enhances diagnostic accuracy.

Objective:To analyze the condition of subclinical atherosclerosis (SCA) in patients with psoriatic arthritis (PsA) and to provide a reference for better management of the associated cardiovascular risk in patients with PsA.Methods:Based on the cohort of PsA patients (PKUPsA) in the Department of Rheumatism and Immunology, Peking University First Hospital, 240 PsA patients without previous clinical atherosclerotic disease between July 2018 and June 2024 were included. The demographic data traditional cardiovascular disease risk factors, PsA related indicators and medications were collected when all patients were entered into the cohort. Increased intima-media thickness and/or arterial plaque formation in bilateral carotid arteries examined by ultrasonography are defined as the presence of SCA. Based on this, patients were divided into SCA and no SCA groups, and the two groups were compared and analyzed. Statistics were performed using the Mann-Whitney U test, independent sample t test, χ2 test and Logistic regression analysis. Results:Eighty-five of 240 patients (35.4%) had SCA, including 55 (22.9%) with cIMT thickening and 51 (21.2%) with carotid plaque. Compared with the PsA patients without SCA, patients with SCA were older [55.0 (42.0, 62.5) vs. 42.0(35.0, 53.0) year of age, Z=-4.90, P<0.001], had longer disease course of arthritis [4.6 (1.0, 10.1) vs. 3.0(1.0, 6.1) years, Z=-1.98, P=0.048], more patients with combined hypertension [34.1%(29/85) vs. 15.5%(24/155), χ2=11.08, P<0.001], hyperlipidemia [47.1%(40/85) vs. 27.1%(42/155), χ2=1.22, P=0.002] and the taking of statins [14.1%(12/85) vs. 5.8%(9/155), χ2=4.75 , P=0.029], hypoglycemic agents [10.6%(9/85) vs. 3.9%(6/155), χ2=4.23, P=0.040] and antihypertensive drugs [17.6%(15/85) vs 6.5%(10/155), χ2=7.37, P=0.007]. They also had a higher blood glucose level[5.37 (5.17, 6.09)mmol/L vs. 5.26(4.97, 5.67)mmol/L, Z=-2.82 , P=0.005], low-density lipoprotein [(3.05± 0.76)mmol/L vs. (2.78±0.75)mmol/L, t=2.60, P=0.010] and blood uric acid level[351 (312, 412)μmol/L vs. 333(279, 408)μmol/L, Z=-2.10, P=0.036]. Multivariate analysis showed that older [ OR (95% CI) =1.059 (1.033, 1.086), P<0.001], increased low density lipoprotein [ OR (95% CI) =1.519 (1.018, 2.267), P=0.041] and increased blood uric acid levels [ OR (95% CI)=1.004 (1.001, 1.007), P=0.017] were an independent risk of SCA in PsA patients. Conclusion:More than 1/3 of PsA patients with SCA without past history of clinical atherosclerosis with SCA, advanced age, increased blood low density lipoprotein level, and elevated uric acid level are independent risk factors for PsA with SCA, so attention should be paid to the assessment and management of cardiovascular-related risk. Early intervention can help to improve patient prognosis.

Objective:Treat-to-target strategies for psoriatic arthritis (PsA) have been proposed for several years, however, the status of target and goal achievement in China is unknown. Therefore, we aimed to investigate the target achievement of PsA patients, and differences of treatment goals were further analyzed.Methods:A total of 360 PsA patients from Peking University First Hospital PsA patient cohort (PKUPsA) between January 2016 and March 2024 were included. We retrospectively analyzed the disease activity of patients at their enrollment. Minimal disease activity (MDA), disease activity index for PsA (DAPSA), clinical DAPSA (cDAPSA) and disease activity score based on 28 joint counts (DAS28) were evaluated. Interclass correlation coefficient (ICC) was used to test the consistency of all these assessments.Results:Three hundred and sixty patients were included in this study, with 149 females (41.4%), median age 47 (36, 57) years and duration of PsA for 2.0(1.0, 6.8) years. 129 (35.8%) patients reported family history of PsO. The most common comorbidities were hyperlipidemia (101, 28.1%) and hypertension (78, 21.7%). There were 217 (60.3%), 75 (20.8%) and 18 (5.0%) patients treated with conventional synthetic DMARDs, biologics and JAK inhibitors respectively. Forty-nine (13.6%) patients ever received intra-articular injection of glucocorticoid. Based on the different definitions, the rates of target achievement were 33.9% (MDA), 56.1% (DAPSA), 60.8% (DAS28-ESR), 63.9% (DAS28-CRP) and 64.2% (cDAPSA). The main limiting factors for MDA attainment among those who had achieved DAPSA or DAS-defined targets were pain VAS, Psoriasis Area and Severity Index (PASI), tender/swollen joint count, patient global assessment, HAQ, and number of enthesitis, based on leeds Enthesitis Index(LEI). The ICCs of these evaluation methods were 0.489~0.819 ( P<0.001). The consistency was the best between DAPSA and cDAPSA, medium between DAS28-CRP and DAS28-ESR, and worst between MDA and DAS28-CRP. Moreover, DAPSA was more consistent with DAS28 than cDASPA. MDA showed moderate consistency with all other assessments. Conclusion:33.9%~64.2% of PsA patients achieved targets based on different definitions. MDA was the most stringent target, while cDAPSA was the most loose one. In general, MDA was not well consistent with other assessments.

Objective:To explore the differences in the CVD risk and lipid profiles in psoriatic arthritis (PsA) patients with different disease activity and investigate lipid management status in Chinese patients with PsA.Methods:Patients were enrolled from PKUPsA-PC cohort in Peking University First Hospital from January 2016 to January 2024. Data were collected at their first visit, including disease activity score, lipid profiles and treatment. Two modified CVD risk prediction models (modified China-PAR and modified FRS-CVD) were applied to predict the CVD risk over 10 years. All enrolled patients were subsequently stratified into low, intermediate and high-risk groups. The status of lipid target achievement was assessed based on lipid management recommendations proposed by prediction models. In addition, DAPSA was used to stratify PsA patients into remission, low, moderate and high-disease activity groups, and the differences in CVD risk and lipid profiles among PsA patients with different disease activity status were explored. The t test was used for comparison between 2 groups for measures that conformed to normal distribution; the Mann-Whitney U test was used for comparison between 2 groups for measures that were skewed; and the chi-square test was used for comparison between 2 groups for categorical data.Results:Three hundred and seven PsA patients were included in this study. They were aged 47 (36, 57) years with 121 (39.4%) female, disease duration of skin lesions of 14 (7, 23) years and disease duration of PsA for 3 (1, 8) years. There were 148 (48.2%) patients with dyslipidemia, and 38 (25.7%) of them were receiving lipid lowering drugs. By the modified China-PAR model, there were 174 (56.7%), 76 (24.8%) and 57 (18.5%) in the low-, moderate- and high-risk groups. By the modified FRS-CVD model, there were 173 (56.4%), 58 (18.9%) and 76 (24.7%) patients in the corresponding groups. According to the recommendations for lipid management based on FRS-CVD model, 80 (26.1%) patients did not achieve the target of lipid profile, including 9/174 (5.2%) in the modified model low-risk group, 20/76 (26.3%) in the intermediate-risk group, and 51/57 (89.5%) in the high-risk group, but there were only 12 (15.0%) patients receiving statin therapy. Compared with the remission and low disease activity groups, patients in the moderate-to-high disease activity group were older [50 (37, 60) years vs. 43 (35, 55) years, Z=-2.42, P=0.016]; had a higher proportion of hypertension (30.3% vs. 15.0%, χ2=9.60, P=0.002); and had lower HDL-C levels [1.1 (0.9, 1.3) mmol/L vs. 1.2 (1.0, 1.4) mmol/L, Z=-3.18, P=0.001]. Under the modified China-PAR and modified FRS-CVD risk prediction models, a higher proportion of patients with high disease activity in PsA were stratified at high 10-year CVD risk compared with the remission and low disease activity groups (29.5% vs. 19.6%, χ2=3.81, P=0.005) and (23.5% vs. 12.4%, χ2=6.00, P=0.014). Conclusion:Nearly half of the PsA patients are at medium-high risk to CVD. CVD risk is significantly higher in patients with moderate to high disease activity than in patients with remission and low disease activity. HDL-c levels are lower in patients with high disease activity. Nevertheless a quarter of patients did not achieve the target of lipid profile, and few patients are receiving statin. More attention should be paid to CVD risk evaluation and lipid management as a part of treat-to-target strategy to improve the prognosis.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

Objective To evaluate the diagnostic value of positive serum specific antibodies to Mycoplasma pneumoniae(MP)in children with Mycoplasma pneumoniae pneumonia(MPP).Methods PubMed,Cochrane Library,Embase,Sinomed,CNKI,Wanfang and VIP databases were searched for studies on the detection of MPP based on antibodies from the establishment of the database to March 31,2023.After literature screening and data extraction,STATA 16.0 software was used for Meta-analysis.Results A total of 9 literatures and 2 148 clinical samples were included.The combined sensitivities[M(95%CI)]of particle agglutination assay(PA)and enzyme-linked immunosorbent assay(ELISA)were 50%(31～69)and 88%(85～90),and the combined specificities[M(95%CI)]were 88%(76～95)and 88%(62～97).The combined diagnostic odds ratio(DOR)[M(95%CI)]were 5.61(3.30～9.53)and 43.82(12.78～150.19),and the summary receiver operating characteristic curve(SROC)area under the curve(AUC)were 0.80 and 0.88,respectively.Conclusion Serum MP specific antibody detection can be used for diagnosis and screening of children MPP,but needs to be combined with clinical symptoms improve the accuracy of the diagnosis.

Polycystic ovary syndrome (PCOS) is a common reproductive and metabolic disorder, with symptoms of menstrual disorders, hirsutisms, acne, and obesity. Studies have found that PCOS patients have a higher prevalence of anxiety, depression and sleep disorders than non-PCOS women, which may be related to the abnormal innervation. Meanwhile, it has been found that PCOS patients exhibit lower central level and higher peripheral levels of monoamine neurotransmitters (5-hydroxytryptamine, dopamine and norepinephrine). These imbalances can affect various clinical manifestations of PCOS, including the formation and development of metabolic and reproductive disorders, as well as anxiety and sleep disorders, through multiple pathways. This review summarizes recent research progress on the role of monoamine neurotransmitters in the physiological characteristics and clinical manifestations of PCOS patients, aiming to provide new insights into the neuroendocrine characteristics and pathogenesis of the syndrome.

Healthcare providers should pay attention to the oral health status of elderly diabetic patients and provide targeted nursing interventions and recommendations based on the influencing factors of oral frailty, in order to reduce its occurrence.

Pancreaticoduodenectomy (PD) is a primary surgical approach for treating mali-gnant tumors of the pancreatic head and the periampullary region. With the advance in medical technology in recent years, the long-term survival rate of patients undergoing PD has significantly improved, and the incidence of early perioperative complications has markedly decreased. However, current researches predominantly focuse on early postoperative complications, while, limited studies addressing long-term complications. Long-term complications after PD have a significant impact on patients′ quality of life and long-term survival. This authors systematically summarize the common long-term complications following PD, and explore their mechanisms, clinical manifestations, dia-gnostic methods, and treatment strategies, aiming to provide a reference for clinical practice.
