The ED 50 of remimazolam was significantly higher in smoking groups than in non-smoking group ( P<0.05). The ED 50 of remimazolam gradually increased in mild, moderate and heavy smoking groups ( P<0.05). Conclusions:Smoking can decrease the sedative potency of remimazolam when combined with alfentanil in patients undergoing painless gastroscopy.

Objective To analyze the clinical efficacy of"Siming Acupoint"massage technique in the treatment of true myopia in children and adolescents,and explore the related factors influencing the therapeutic effect.Methods From January 2021 to January 2024,257 cases of children and adolescents with true myopia and 475 eyes treated and followed up at the Pediatric Massage Center of Shandong Hospital of Traditional Chinese Medicine were included in this study.And they were divided into the low myopia group(374 eyes),the moderate myopia group(76 eyes)and the high myopia group(25 eyes).The clinical efficacy was analyzed by comparing the observation indicators changes before and after the intervention.The occurrence of ineffective treatment was observed,and the related factors of ineffective treatment were explored by using univariate comparison and multivariate Logistic regression analysis.Results Clinical results showed that the effective rate of 257 children and 475 eyes was 93.05%;the effective rate of 374 eyes in the low myopia group was 98.13%;the effective rate of 76 eyes in the moderate myopia group was 81.58%;the effective rate of 25 eyes in the high myopia group was 52.00%.The score of visual fatigue symptoms after the intervention was significantly lower than that before the intervention(P<0.001);The naked eye vision after the intervention was significantly higher than that before the intervention(P<0.001);After the intervention,NRA and PRA were significantly enhanced compared with those before the intervention(P all<0.001).Risk factor analysis of ineffectiveness showed that there were 33 eyes in the ineffective group and 442 eyes in the effective group.The proportion of patients with a history of sweet tooth in the ineffective group was significantly higher than that in the effective group(P=0.020);The course of disease in the ineffective group was significantly longer than that in the effective group(P=0.001);And there were also significant differences in the degree of myopia between the two groups,the proportion of high myopia in the ineffective group was significantly higher than that in the effective group(P<0.001);The spherical diopter,equivalent spherical diopter and cylindrical diopter in the ineffective group were all significantly higher than those in the effective group(P all<0.001);The axial length of the eye in the ineffective group was significantly longer than that in the effective group(P=0.005);The naked eye vision before treatment and the corrected naked eye vision at the first treatment in the ineffective group were both worse than those in the effective group(both P<0.001);The proportion of patients with outdoor activities<2 hours/day and the proportion of patients with night sleep time<7 hours/day in the ineffective group were significantly higher than those in the effective group(P=0.022,P=0.012).Binary multivariate Logistic regression analysis showed that combined outdoor activities<2 hours/day(OR=8.270,P<0.001),equivalent spherical diopter(OR=2.724,P=0.005),and night sleep time<7 hours/day(OR=2.507,P=0.014)were the risk factors for ineffective treatment of true myopia in children and adolescents with"Siming Acupoints"massage technique.The ROC curve showed that the area under the curve for outdoor activities<2 hours/day was 0.603;The area under the curve for equivalent spherical diopter was 0.678;the area under the curve for night sleep time<7 hours/day was 0.667.Conclusion The"Siming Acupoints"massage technique may be able to improve the naked eye vision of patients,improve NRA,PRA and visual fatigue symptoms,and control the growth of axial length and equivalent spherical diopter.Outdoor activities<2 hours/day,equivalent spherical diopter,and night sleep time<7 hours/day are the risk factors for ineffective treatment of true myopia in children and adolescents with"Siming Point"massage technique.

Objective To investigate the value of the novel lymphatic contrast-enhanced ultrasound(LCEUS)and conventional venous contrast-enhanced ultrasound(VCEUS)in the differential diagnosis of benign and malignant cervical lymph nodes in patients with thyroid cancer. Methods Patients with suspected thyroid cancer underwent conventional ultrasound,VCEUS,and LCEUS examinations of cervical lymph nodes before biopsy.The diagnostic abilities of conventional ultrasound,VCEUS,and LCEUS were compared with pathological results as the golden standard. Results Forty-four patients with 52 lymph nodes were included in the final data.Thirty-eight metastatic lymph nodes were confirmed by pathological results,and 14 were benign.The diagnostic sensitivity,specificity,and accuracy were 97.37%,71.43%,and 90.38% for LCEUS,92.11%,35.71%,and 76.92% for VCEUS,and 94.74%,21.43%,and 75.00% for conventional ultrasound,respectively.The area under the curve of LCEUS analyzed by the receiver operating characteristic curve was greater than that of VCEUS(P=0.020)and conventional ultrasound(P<0.001). Conclusion LCEUS could significantly improve the differential diagnosis of cervical lymph node metastasis in the patients with thyroid cancer,providing a basis for precise clinical treatment.

Objective To compare the diagnostic value of transabdominal intestinal ultrasound (IUS) and magnetic resonance enterography (MRE) for intestinal stenosis in inflammatory bowel disease (IBD). Methods A retrospective analysis was conducted on the imaging features of 51 IBD patients who underwent both IUS and MRE at Beijing Friendship Hospital,Capital Medical University,between January 2021 and February 2025.With endoscopy as the gold standard,the diagnostic performance of the two methods was compared. Results The sensitivity (84.2% vs. 52.6%,P=0.008) and accuracy (66.7% vs. 45.1%,P=0.035) of IUS for stenosis were higher than those of MRE.In the localization of stenosis,IUS demonstrated higher sensitivity than MRE for detecting stenosis in the terminal ileum (78.6% vs. 35.7%,P=0.070) and colorectum (86.7% vs. 53.3%,P=0.060).Furthermore,IUS showed higher diagnostic accuracy than MRE for terminal ileum stenosis (70.6% vs. 29.4%,P=0.039).The intestinal wall thickness[(8.2±2.7) mm vs. (10.3±3.8) mm;t=3.20,P=0.002)] and stenosis inner diameter[(3.0±1.6) mm vs. (4.3±1.8) mm;t=2.15,P=0.035] measured by IUS were lower than those measured by MRE,with a moderate level of consistency (ICC:0.19-0.53).In addition,IUS demonstrated a higher detection rate for mesenteric fat hypertrophy (70.6% vs. 27.5%,Kappa=0.27,P=0.005),whereas MRE was more sensitive in detecting lymphadenopathy (90.2% vs. 56.9%,Kappa=0.16,P=0.080). Conclusions IUS is superior to MRE in the diagnosis and localization sensitivity for intestinal stenosis in IBD.However,the two methods showcase poor consistency in detecting and quantitating some inflammatory signs.IUS can be used as a first-line screening method for diagnosing intestinal stenosis in IBD patients,while its clinical application should be combined with specific needs to optimize diagnosis.
