Objective:To investigate the feasibility of transcatheter edge-to-edge repair (TEER) using a short-clip strategy for patients with moderate-to-severe or greater degenerative mitral regurgitation caused by commissural prolapse.Methods:This retrospective study included patients with severe mitral regurgitation secondary to commissural prolapse who underwent TEER at the Second Affiliated Hospital of Zhejiang University School of Medicine between September 2022 and July 2024. Preoperative clinical and imaging data, intraoperative details, procedural outcomes, and 1-month postoperative follow-up results were collected.Results:A total of 19 patients were enrolled, aged (74.1±6.1) years, including 12 males. Among them, 10 patients had external commissural prolapse, and 9 patients had internal commissural prolapse. Preoperatively, all patients exhibited severe mitral regurgitation (4+), with an effective regurgitant orifice area of (0.55±0.17) cm2, left atrial volume of (104.77±36.57) ml, left ventricular end-diastolic volume of (102.29±32.47) ml, left ventricular end-diastolic dimension of (5.34±0.59) mm, and prolapse width of (1.18±0.34) cm. All procedures utilized short clips (NTR or NTW clips) to target the prolapsed commissural region and were completed successfully without intraoperative complications. At 1-month follow-up, no mortality, stroke, single-leaflet device attachment, myocardial infarction, or unplanned mitral reintervention occurred. Mitral regurgitation severity improved to ≤2+ in all patients, with left atrial volume of (74.49±33.83) ml, left ventricular end-diastolic volume of (85.90±18.05) ml, and left ventricular end-diastolic dimension of (4.93±0.37) mm (all P<0.05). Conclusion:The short-clip strategy, focusing on precise clip placement at the commissural interface, is feasible and effective for TEER in patients with severe mitral regurgitation due to commissural prolapse.

Inflammatory bowel disease (IBD) is a progressive and destructive chronic intestinal inflammatory disease. Fatigue is one of the most common symptoms of IBD patients, which has a negative impact on the quality of life of patients. Its subjectivity and complexity make it difficult for clinicians to evaluate. Fatigue is always overlooked in clinical works. The mechanism of fatigue is unclear and there is no effective therapy to alleviate fatigue in IBD for now. We mainly review the research progress of influencing factors and therapy of fatigue in IBD patients to help clinicians have better awareness of fatigue.

Objective:To explore the effect of the pharyngeal pressure feedback training on pharyngeal constriction in persons with swallowing disorders caused by brainstem lesions.Methods:Twenty patients with disordered swallowing caused by a brainstem lesion were randomly divided into a control group and an intervention group, each of 10. Both groups received routine swallowing training including oral sensorimotor training, neuromuscular stimulation and balloon catheter dilation, while the intervention group was additionally provided with two weeks of pharyngeal pressure feedback training. Before and after the treatment, both groups were evaluated in terms of the peak pressure of superior and inferior pharyngeal constriction, endoscopically and also using the functional oral intake scale.Results:There was no significant difference between the two groups in any measure before the intervention. Afterward, both groups had improved significantly by all of the measurements, but the average peak upper pharyngeal pressure, the average intake scale score and the endoscopy results of the intervention group were all significantly better than the control group′s averages.Conclusions:Pharyngeal pressure feedback training can significantly relieve swallowing disorders caused by brainstem lesions.

s] Objective To evaluate the effect of comprehensive schistosomiasis control measures with focus on total removal of cattle and sheep in Junshan District,Yueyang City. Methods The retrospective review and field survey were implemented in the pilot villages in Junshan District. The data of Schistosoma japonicum infection status of human,cattle,sheep and Oncome-lania hupensis snails,and density of snails were gathered and modeled in the period of 2006 to 2016. Results The prevalence of schistosome infection in residents in the pilot villages decreased from 3.44％ in 2006 to 0.59％ in 2012(F = 14.501,P =0.013). After removal of all the cattle and sheep in 2013,the prevalence of schistosome infection in the residents decreased to zero in 2016(F=14.148,P=0.033). The density of living snails decreased from 0.8833/0.1 m2 in 2006 to 0.3088/0.1 m2 in 2012(F=76.250,P=0.005). Conclusion The comprehensive schistosomiasis control strategy with focus on cattle and sheep removal is remarkably effective.

Objective: This study aimed to compare and analyze the functional differences between peripheral blood mono-cyte-derived dendritic cells (DCs) of Helicobacter pylori-positive and H. pylori-negative patients with gastric cancer. Methods:H. py-lori infection was detected in 84 patients with gastric cancer in our hospital from January 2011 to October 2012 by the 14C-urea breath test. DCs were generated from monocytes isolated by an adherent method from the two groups of patients and cultured in the presence of rhIL-4, rhGM-CSF, and rhTNF-α. Furthermore, the expression of surface marker molecules was determined by fluorescence-activat-ed cell sorting analysis. The cytotoxicity of DCs pulsed T cells against gastric carcinoma cell was assessed by the lactate dehydroge-nase-releasing assay. The secretion of IL-12 and IFN-γin the supernatant was determined by enzyme-linked immunosorbent assay. Re-sults:No difference was observed in the morphological change of the maturation process. The mean expression of CD1a, CD80, CD83, CD86, and HLA-DR molecules in DCs of H. pylori-infected patients was higher than that in DCs of H. pylori-negative group, and the differences were statistically significant except for CD1a and HLA-DR. The cytotoxicity activities, IL-12 release, and IFN-γrelease in the H. pylori-positive group were significantly higher than those in the H. pylori-negative group (P<0.05). Conclusion:H. pylori infec-tion has no effect on the morphological change of the maturation process of monocyte-derived DCs. These data clearly demonstrate that monocyte-derived DCs of H. pylori-infected patients with gastric cancer can induce stronger maturation and activation than those of H. pylori-negative patients.
