Background and Aims:Spontaneous isolated superior mesenteric artery dissection(SISMAD)is a relatively common type of visceral artery dissection,typically presenting with acute abdominal pain.In severe cases,it may lead to intestinal ischemia or even necrosis.With the widespread use of imaging techniques such as CT angiography(CTA),the detection rate of SISMAD has significantly increased.However,there is still controversy regarding its optimal treatment strategy,especially in choosing between conservative management and endovascular intervention,as no unified standard currently exists.This study aimed to compare the short-and medium-term outcomes of the two treatment modalities by retrospectively analyzing the clinical data of SISMAD patients treated at our center in order to provide evidence for individualized treatment decisions.Methods:A retrospective analysis was conducted on 174 patients diagnosed with SISMAD at Ningbo Second Hospital between January 2018 and December 2023.Among them,30 patients received conservative treatment,and 144 underwent endovascular intervention(including stent implantation alone or in combination with coil embolization of the false lumen).All patients were diagnosed using CTA or superior mesenteric artery angiography and classified accordingly.Patients were followed up at 1 month and 1 year after treatment to assess clinical symptom relief and radiological outcomes,including dissection remodeling and stent patency.Results:In the conservative group,the symptom relief rate was 90.0%at 1 month and 92.8%at 1 year;in the interventional group,the corresponding rates were 99.3%and 98.6%.The difference in symptom relief at 1 month was statistically significant(P=0.016),while the difference at 1 year was not(P>0.05).Subgroup analysis by classification showed that the interventional group generally had higher symptom relief rates than the conservative group across all types.However,none of the differences reached statistical significance(all P>0.05).The conservative group showed poorer symptom control in type Ⅲpatients,including one death.The technical success rate of endovascular treatment was 99.3%,with no cases of stent displacement or occlusion within 1 year.The complete remodeling rate was 86.8%,and the stent patency rate was 100.0%.Some patients had minor mural thrombus formation within the stent without evidence of flow obstruction.Conclusion:Endovascular intervention offers a high technical success rate and favorable short-and medium-term efficacy in SISMAD patients,particularly for type Ⅱ and Ⅲ cases with compromised true lumen perfusion.Treatment strategies should be tailored based on the dissection type and the degree of true lumen compression to improve clinical outcomes and reduce associated risks.

Objective:To explore the effect of ultrasound-guided stellate ganglion block (SGB) combined with cognitive behavioral therapy for insomnia (CBT-I) in the treatment of chronic insomnia.Methods:A total of 69 patients with chronic insomnia admitted to the Nanjing First Hospital from January 2023 to February 2024 were selected and randomly divided into the CBT-I alone group (simple group, 34 cases) and the SGB combined with CBT-I group (combined group, 35 cases) using a random number table. Both groups received treatment for 8 weeks. The simple group was treated with CBT-I twice a week, 1 hour each time. The combined group, on the basis of the simple group, received ultrasound-guided SGB with 4 ml of 1% lidocaine, which was performed once a day, alternately on the left and right sides, for 7 consecutive days each time, with a total of 14 injections in the 1st and 5th weeks. One week before treatment and 8 weeks after treatment, the Pittsburgh Sleep Quality Index (PSQI) and sleep diary were used to record patients′ subjective sleep quality; Actigraph was used to record objective sleep status; the Self-rating Anxiety Scale (SAS) and Self-rating Depression Scale (SDS) were used to assess patients′ emotional status. Adverse reactions such as hoarseness, pneumothorax, bleeding, and infection were recorded.Results:After 8 weeks of treatment, the effective rate was 76.5%(26/34) in the simple group and 94.3%(33/35) in the combined group, with a statistically significant difference (χ 2=8.433, P<0.05). Before treatment, there was no significant difference in PSQI scores between the two groups ( P>0.05). After 8 weeks of treatment, the PSQI scores of both groups were lower than those before treatment, and the PSQI score of the combined group was lower than that of the simple group, with a statistically significant difference ( P<0.05). Before treatment, there were no significant differences in sleep parameters from sleep diaries and Actigraph between the two groups (all P>0.05). Compared with before treatment, after treatment, the total sleep time and time in bed were prolonged, and sleep efficiency, the proportion of deep sleep, and the proportion of rapid eye movement sleep were increased in both groups; these indicators in the combined group were better than those in the simple group, with statistically significant differences (all P<0.05). Compared with before treatment, the sleep onset latency was shortened and the number of awakenings was reduced in both groups after treatment, and the combined group was better than the simple group, with statistically significant differences (all P<0.05). Before treatment, there were no significant differences in SAS and SDS scores between the two groups (all P>0.05). After treatment, the SAS and SDS scores of both groups were lower than those before treatment, and the SAS and SDS scores of the combined group were lower than those of the simple group, with statistically significant differences (all P<0.05). During treatment, 2 cases in the combined group developed hoarseness, which relieved spontaneously after 2 hours, and no other complications occurred. Conclusions:Ultrasound-guided SGB combined with CBT-I can significantly improve the nighttime sleep quality of patients with chronic insomnia.

The contents recorded in the rotation registration manual is not only the quantitative indicators for evaluating the quality of residency training, but also the important basis for training assessment and issuance of training certificates. In order to solve the problems of data authenticity, information delay, and repeated entry in the rotation registration manual for residency training, Shanghai East Hospital, Tongji University, launched a project to dock the electronic rotation registration manual with the hospital information system. Through the establishment of the project team, the development of working mechanisms, and the implementation of the project, data analysis was used for process reformation and system optimization, so as to continuously improve management efficiency and medical safety while solving problems and form a set of implementation system with reference significance in practice.

This article describes the experience of implementing the informatization construction of teaching supervision for standardized residency training in Shanghai East Hospital, Tongji University, and discusses the means to improve teaching activity supervision, such as management informatization and internet technology. This study aims to ensure the efficiency and work quality of supervision, optimize the process and resource allocation of supervision, and lay a solid foundation for improving the quality of residency training and teaching in the hospital (especially the key indicators for residency training and teaching quality, including the supervision rate of teaching activities and the completion rate of teaching activities) and establishing a sound system and the assets of teaching data in residency training.
