Objective: To analyze the epidemiological characteristics of mumps in Shanxi Province from 2014 to 2023, so as to provide scientific evidence for targeted prevention strategies. Methods: Mumps case data in Shanxi Province were obtained from the China Information System for Disease Prevention and Control. Descriptive epidemiological analysis and age-period-cohort (APC) analysis were carried out on the reported incidence of mumps from 2014 to 2023. Results: A total of 44 360 mumps cases were reported in Shanxi Province from 2014 to 2023, with an average annual incidence rate of 11.78/100 000. The incidence rates were high during 2017-2019, which were 21.00/100 000, 16.76/100 000, and 19.51/100 000, respectively. Males had a higher incidence rate (13.50/100 000) than females (9.98/100 000). Children aged 5-9 years were the most affected group, accounting for 47.29% of total cases. In 2017 and 2019, incidence rates among the 5-15-year-old group were particularly high, reaching 155.08/100 000 and 131.78/100 000, respectively. The APC model age effect, period effect and cohort effect of the reported incidence rate in the high-incidence population aged 0-20 years all had statistical significance ( P <0.05). The age-relative risk ( RR ) decreased from 1.75 in the 0-year-old group to 0.33 in the 20-year-old group, and the birth cohort RR decreased from 2.58 in 1994 to 0.26 in 2023. The morbidity risk of the population aged 0-20 years showed a trend of first increasing and then decreasing over time, among which it was the highest in 2017 ( RR =1.23) and the lowest in 2023 ( RR =0.29). Conclusions Shanxi exhibits cyclical mumps epidemics, with school-aged children as the high-risk population. School health management work should be carried out, and the surveillance of mumps in high-risk areas and the routine vaccination of two doses of mumps-containing vaccines for eligible children should be strengthened.

Sustained inflammatory responses are closely related to various severe diseases, and inhibiting the excessive activation of inflammasomes and pyroptosis has significant implications for clinical treatment. Natural products have garnered considerable concern for the treatment of inflammation. Huanglian-Wumei decoction (HLWMD) is a classic prescription used for treating inflammatory diseases, but the necessity of their combination and the exact underlying anti-inflammatory mechanism have not yet been elucidated. Inspired by the supramolecular self-assembly strategy and natural drug compatibility theory, we successfully obtained berberine (BBR)-chlorogenic acid (CGA) supramolecular (BCS), which is an herbal pair from HLWMD. Using a series of characterization methods, we confirmed the self-assembly mechanism of BCS. BBR and CGA were self-assembled and stacked into amphiphilic spherical supramolecules in a 2:1 molar ratio, driven by electrostatic interactions, hydrophobic interactions, and π-π stacking; the hydrophilic fragments of CGA were outside, and the hydrophobic fragments of BBR were inside. This stacking pattern significantly improved the anti-inflammatory performance of BCS compared with that of single free molecules. Compared with free molecules, BCS significantly attenuated the release of multiple inflammatory mediators and lipopolysaccharide (LPS)-induced pyroptosis. Its anti-inflammatory mechanism is closely related to the inhibition of intracellular nuclear factor-kappaB (NF-κB) p65 phosphorylation and the noncanonical pyroptosis signalling pathway mediated by caspase-11.

Objective To explore the long-term efficacy of percutaneous pulmonary valve implantation(PPVI)and the durability of the domestic self-expanding Venus P valve.Methods A total of 8 patients with post-surgical right ventricular outflow tract(RVOT)dysfunction,who were admitted to hospital from October 2014 to July 2016 and deemed anatomically suitable for PPVI with self-expanding valve,were included prospectively.Clinical,imaging,procedural and follow-up data were analyzed.The survival rates,perioperative and long-term complication rates,long-term efficacy of PPVI,and long-term function of Venus P in 8 patients were evaluated.The immediate procedural results were evaluated by clinical implant success rate,which is defined as successful valve implantation with echocardiography-assessed pulmonary regurgitation＜moderate and peak trans-pulmonary pressure gradient＜40 mmHg.Results A total of 8 patients were included,with 7 females,aged 14 to 36 years.The initial diagnosis included post-surgical Tetralogy of Fallot(5 cases),post-surgical Trilogy of Fallot(1 case),post-surgical Quadricuspid pulmonary valve stenosis(1 case)and post-surgical Double-Outlet Right Ventricle(1 case).The indications of PPVI included RVOT-pulmonary obstruction and regurgitation(1 case)and isolated regurgitation(7 cases).Clinical implant success was achieved in all of the 8 patients with firmly fixed valve,and there were no such complications as valve detachment,displacement or stent fracture.All patients experienced significant symptom relief after the procedure.The right ventricular end-diastolic volume index(RVEDVi)measured by CMR 6 months after PPVI showed a significant decrease compared to preprocedural values[(89.99±13.85)ml/m2 vs.(144.93±11.28)ml/m2,P=0.001].Postoperative pulmonary regurgitation were significantly improved or disappeared in all patients,and there was no statistically significant difference in the average peak pressure gradient measured by echocardiogram between preoperative and the latest follow-up[(23.25±8.39)mmHg vs.(18.75±6.28)mmHg,P=0.210].Over an average follow-up period of(9.25±0.71)years,1 case of infective endocarditis occurred 5 years after PPVI.During the follow-up,no death,deterioration of heart failure,malignant arrhythmia or other serious complications were observed.All patients completed 8-year follow-up,and 3 completed 10-year follow-up.All patients were graded as NYHA functional class one at the latest follow-up.Conclusions PPVI using the domestically produced self-expanding Venus P is safe and feasible for the treatment of patients with post-surgical RVOT dysfunction and suitable anatomy.Our study confirms the long-term efficacy and durability of Venus P from multiple perspectives,and no severe stent fracture occurred without pre-stent implantation in the native RVOT.

Patients with congenital heart disease combined with right ventricular outflow tract malformations often leave varying degrees of pulmonary regurgitation and/or obstruction after surgical/interventional correction.With the continuation of time,the significant increasement of the right ventricular volume load will affect patients'quality of life and survival,which may require multiple pulmonary valve replacements.Compared with high-risk surgery,percutaneous pulmonary valve implantation is a less invasive,safer and more effective interventional valve replacement technology,which can improve patients' long-term prognosis.With the progress of technology and the improvement of instruments,the indications of percutaneous pulmonary valve implantation have gradually expanded,and have gradually become an alternative treatment of surgical thoracic valve replacement.Combined with the latest research progress of percutaneous pulmonary valve implantation,this paper discusses the change of indications,optimal timing of intervention and instrument selection in recent years.

Objective:To analyze the characteristics of transabdominal bowel ultrasound (TBUS) in immune checkpoint inhibitor-related colitis (IRC) and their correlation with endoscopic manifestations.Methods:A cross-sectional study was conducted. Clinical data from 10 patients with IRC treated at Peking Union Medical College Hospital from January 2022 to January 2024 were collected. The ulcerative colitis endoscopic index of severity (UCEIS) and Limberg classification were used to assess the severity of colonoscopy and TBUS examinations, respectively. Kendall's tau-b method was applied for correlation analysis between UCEIS scores and Limberg classification.Results:All the 10 patients were male with a median age of 65 years (59-74 years). The majority had lung cancer (8 patients) and all were in advanced stages, with 6 patients in stage Ⅲ and 4 in stage Ⅳ. They all received anti-programmed death 1 (PD-1) /anti-programmed death ligand 1 (PD-L1) combined with chemotherapy, among whom 2 patients were combined with anti-angiogenic drug treatment. The median time from the first immunotherapy to the onset of IRC was 1.50 (0.25-12.00) months; the median time from IRC treatment to clinical symptom relief to G1 was 2.45 (0.50-8.00) weeks. Nine patients were in the active phase, mainly G3 (8 patients) ; 1 was in the remission phase after treatment. TBUS showed that among the 9 active IRC patients, the entire colon was mainly involved (7 patients), with combined small intestine involvement (3 patients) ; the main manifestations were thickening of the bowel wall, with the thickest bowel wall being 7.0 (5.0-8.0) mm, mainly located in the sigmoid colon (3 patients) and descending colon (3 patients) ; increased bowel wall blood flow signals (Limberg classification 2-4) occurred in 7 patients; 3 active patients had perienteric fat wrapping, and 2 had blurred bowel wall stratification. The Kendall's tau-b correlation coefficient r between the entire colon UCEIS scores and Limberg classification was 0.891 ( P = 0.003), and the Kendall's tau-b correlation coefficient r between the colon segment UCEIS scores and Limberg classification was 0.690 ( P < 0.001) . Conclusion:During the active phase, the left colon of IRC is more severe in TBUS, which mainly manifests as the thickening bowel wall and increased blood flow signals, and the TBUS has good correlation with colonoscopy evaluation.
