Objective To assess the safety of transeptal puncture(TSP)guided by transthoracic echocardiography(TEE)in percutaneous transcatheter closure of patent foramen ovale(PFO).Methods From March 2022 to December 2022,our department performed TSP guided by TEE in 45 patients with PFO who were unable to pass through the PFO with transcatheter standard technique.After guiding the delivery of the sheath,the foramen ovale was occluded.Results PFO closure with TSP technique guided by transthoracic echocardiography was successfully finished in all the 45 patients,with an operative time of(15.0±3.7)min.No complications such as arrhythmia or cardiac perforation happened immediately and at 12 h after surgery.All the patients recovered and were discharged on the next day after surgery.All the 45 patients were followed up by outpatient echocardiography and dynamic electrocardiogram at 3 months after surgery,and no complications such as intracardiac shunt,pericardial effusion,atrial fibrillation,aortic regurgitation,or arrhythmia were observed.Conclusion TSP guided by TEE is safe and feasible,and it can be used as a supplementary method for complex PFO.

Objective:To analyze the effect of comprehensive rehabilitation intervention on the physical functioning of frail elderly persons.Methods:A total of 318 frail elderly persons were randomly divided into a control group ( n=164) and an observation group ( n=154) to test different interventions. Propensity score matching was used to balance the baseline information between the two groups 1∶1. A total of 200 cases were successfully matched, with 100 cases in each group. Both groups received drug treatment and routine nursing, while the observation group was additionally provided with comprehensive rehabilitation. Before and after 4 weeks of the treatment, both groups were evaluated using visual analogue scale (VAS) scoring for their perception of pain intensity, hand grip strength, gait speed, 6-minute walking distance (6MWD), 5 sit-up time, and the timed up and go test (TUGT). Results:There were no significant differences between the groups in any of the measurements before the experiment. Afterward, all of the outcome measures except gait speed were significantly better among the experimental group than among the controls, on average.Conclusions:Comprehensive rehabilitation can relieve pain, improve the walking, handgrip strength and exercise endurance of the frail elderly.

Objective:To investigate the conversion of stromal vascular fraction (SVF) in the microenvironment of radiation-induced skin injuries to provide guidance for clinical applications.Methods:Based on a random number table, C57BL/6N mice were categorized into four groups: the blank control, negative control, acute injury, and chronic injury groups, with each group containing 25 mice. The backs of mice in the blank control, acute injury, and chronic injury groups were exposed to 15 Gy X-ray irradiation. Then, the mice in the negative control, acute injury, and chronic injury groups were injected subcutaneously with the SVF derived from B6/G-R mice. The survival of these mice was observed 1, 3, 7, 14, and 21 d after the injection through fluorescence tracing and in vivo imaging. Accordingly, the clinical SVF injection regimens were optimized based on the experimental result of mice. Finally, local SVF injection was performed on different frequencies for patients in different wound conditions, with the efficacy being observed. Results:The fluorescence of SVF was observed from the tissue slices of the acute injury, chronic injury, and negative control groups 14 d post-injection. The result showed that the fluorescence intensity of SVF 1, 3, and 7 d post-injection was in the order of the negative control group > the acute injury group > the chronic injury group. The acute injury group ranked at the top and the chronic injury group remained at the bottom 14 d after the injection. The fluorescence of SVF in each group was barely detected 21 d after the injection. Compared to the negative control group, the acute injury group exhibited statistical differences only 14 d post-injection ( t = 4.11, P < 0.05), while the chronic injury group displayed statistical differences 1, 3, 7, and 14 d after the injection ( t = 3.88-5.74, P < 0.05). Furthermore, the acute injury group exhibited significantly higher fluorescence intensity of SVF than the chronic injury group ( t = 4.73-8.38, P < 0.05). The half-life of SVF for the negative control, acute injury, and chronic injury groups was 6.336, 6.014, and 2.163 d, respectively. As indicated by the application of SVF transplantation based on traditional surgical protocols in the clinical trial, SVF can significantly promote wound repair, with earlier SVF transplantation being more beneficial for wound healing. Conclusions:The conversion of SVF differs in the microenvironments of acute and chronic radiation-induced skin injuries. This can serve as an essential guide for the administration timing and injection frequency of SVF in clinical applications.

OBJECTIVE: To analyze the clinical and genetic features of three patient diagnosed with Kleefstra syndrome. METHODS: Whole exome sequencing (WES) was carried out for the probands and their parents. Suspected variants were validated by Sanger sequencing. Copy number variations (CNV) were detected by CNV-seq and validated by real-time PCR. RESULTS: Proband 1 was found to carry a de novo heterogeneous variant (c.823+1G>T) of the EHMT1 gene, which may affect its expression. Based on the guidelines of the American College of Medical Genetics and Genomics, the variant was predicted to be pathogenic (PVS1+PS2+PM2). Proband 2 was found to carry a de novo missense variant c.439C>G (p.L147V) of the EHMT1 gene, which was predicted to be likely pathogenic (PS2+PM1+PM2+PP3). Proband 3 was found to carry a heterozygous 520 kb deletion at 9q34.3 by CNV-seq. The deletion has encompassed the whole of the EHMT1 gene. Real-time PCR has detected no CNV of this region in her parents. CONCLUSION Variants of the EHMT1 gene probably underlay the disease in these patients. Genetic testing has provided a basis for their clinical diagnosis.

Objective:To investigate the MRI features of progressive multifocal leukoencephalopathy (PML) in acquired immunodeficiency syndrome (AIDS) patients, and to provide evidence for clinical diagnosis, evaluation and staging.Methods:Form Janurary 2016 to April 2018, 11 AIDS patients with clinical diagnosis of PML were enrolled at Zhongnan Hospital of Wuhan University. A total of 25 MRI examination data of 11 patients (5 patients underwent multiple examinations) were reviewed. The distribution, morphology and signal characteristics of the lesions were analyzed, and the changes of the lesions between multiple MRI examinations were compared. The lesions of all 25 MR images were staged according to MR features.Results:Typical image findings of PML included confluent, bilateral but asymmetric distributed, supratentorial white matter abnormal signal lesions. The parietal lobe was most commonly involved, followed by the frontal lobe. The lesions often showed hypointensity on T 1 and hyperintensity on T 2 weighted images. No obvious mass effect or enhancement was found. In advanced stage, multifocal white matter lesions were enlarged in size and more confluent, displaying large patchy abnormal signal intensity, with gradually involving the deep white matter, and occasionally combing with gray matter and cerebellar lesions. The disease showed heterogenous signal intensity due to necrosis in the lesion. The newly appeared lesions showed obvious diffusion restriction, demonstrating high signal intensity on diffusion weighted imaing with low apparent diffusion coefficient value. The main finding of the later stage was necrosis, with focal asymmetric brain atrophy was observed. Conclusions:PML in AIDS patients has characteristic MRI findings, and MRI features varies in different stages. MRI can be helpful in clinical diagnosis, evaluation and staging of PML.

Objective:This study aims to analyze the prognosis of patients who underwent a simultaneous operations for colorectal cancer and liver metastases, and to establish a prognostic scoring system for these patients.Methods:From January 2010 to March 2019, the clinicopathological data of patients with colorectal cancer and liver metastases simultaneously operated at Shanghai Changhai Hospital were collected. The clinicopathological prognostic factors on tumor recurrence and survival outcomes on follow-up were analyzed. Single and multiple factors Cox regression analyses were used to determine the risk factors which affected the prognosis of patients. Using the risk factors of poor prognosis on Cox analysis, 1 point was given to each risk factor. Patients were then divided into different groups according to the different total scores. The median overall survival and disease-free survival of each group were analyzed.Results:Of 234 patients included in this study, there were 126 males and 108 females. The average age was (57.4±10.8) years. The median survival was 44.85 months. The 1-, 3-, and 5-year survival rates of the whole group were 87.3%, 55.2%, and 22.9%, respectively. Primary tumor in right colon, preoperative carcinoembryonic antigen ≥200 ng/ml, multiple liver metastases, and poorly differentiated adenocarcinoma/mucinous adenocarcinoma were independent risk factors of poor prognosis. After 1 point was given to each of the above 4 items, patients were then divided into the low-risk (0-1) and high-risk (2-4) groups. The median survivals of patients in the low-risk group ( n=174) and high-risk group ( n=60) were 53 months and 29 months, respectively. The corresponding median disease-free survivals were 21.34 months and 8.48 months, respectively. The differences between the 2 groups were significant ( P<0.05). Conclusion:The results of this study preliminary established a predictive scoring system for patients with simultaneous colorectal cancer and liver which can play a role in selecting treatment options for these patients.
