Purpose: The aim of this study was to investigate the feasibility of an intelligent handheld ultrasound (US) device for assisting non-expert general practitioners (GPs) in detecting carotid plaques (CPs) in community populations. Methods: This prospective parallel controlled trial recruited 111 consecutive community residents. All of them underwent examinations by non-expert GPs and specialist doctors using handheld US devices (setting A, setting B, and setting C). The results of setting C with specialist doctors were considered the gold standard. Carotid intima-media thickness (CIMT) and the features of CPs were measured and recorded. The diagnostic performance of GPs in distinguishing CPs was evaluated using a receiver operating characteristic curve. Inter-observer agreement was compared using the intragroup correlation coefficient (ICC). Questionnaires were completed to evaluate clinical benefits. Results: Among the 111 community residents, 80, 96, and 112 CPs were detected in settings A, B, and C, respectively. Setting B exhibited better diagnostic performance than setting A for detecting CPs (area under the curve, 0.856 vs. 0.749; P<0.01). Setting B had better consistency with setting C than setting A in CIMT measurement and the assessment of CPs (ICC, 0.731 to 0.923). Moreover, measurements in setting B required less time than the other two settings (44.59 seconds vs. 108.87 seconds vs. 126.13 seconds, both P<0.01). Conclusion Using an intelligent handheld US device, GPs can perform CP screening and achieve a diagnostic capability comparable to that of specialist doctors.

Mutations in the cyclin-dependent kinase-like 5 gene (CDKL5) cause a severe neurodevelopmental disorder, yet the impact of truncating mutations remains unclear. Here, we introduce the Cdkl5^492stop mouse model, mimicking C-terminal truncating mutations in patients. 492stop/Y mice exhibit altered dendritic spine morphology and spontaneous seizure-like behaviors, alongside other behavioral deficits. After creating cell lines with various Cdkl5 truncating mutations, we found that these mutations are regulated by the nonsense-mediated RNA decay pathway. Most truncating mutations result in CDKL5 protein loss, leading to multiple disease phenotypes, and offering new insights into the pathogenesis of CDKL5 disorder.

Objective:To observe the effect of auricular pressure beans(APN)combined with Compound Tung-Leaf Burn Oil(CTBO)on perioperative anxiety and pain in patients undergoing circumcision.Methods:This study included 100 patients undergo-ing circumcision with the disposable circumcision anastomosis stapler in our hospital from August 2023 to November 2023,of whom 50 received routine circumcision nursing care(the control group)and other 50 APN combined with compound CTBO in addition(the ob-servation group).We compared between the two groups the anxiety scores before any intervention,30 minutes before and 24 hours and 10 days after operation,the pain scores 24 hours postoperatively and at the first change of wound dressing,the frequency of 3-day post-operative sleep awakenings,the incidence of complications,and the satisfaction of the patients.Results:Totally,94 patients com-pleted the study,46 in the observation and 48 in the control group.The anxiety scores exhibited no statistically significant difference between the two groups of patients before any intervention(P>0.05),but were markedly lower in the observation than in the control group at 30 minutes before and 24 hours and 10 days after surgery(P<0.05),and so were the pain scores24 hours after surgery and at the first change of wound dressing(P<0.05),and the frequency of 3-day postoperative sleep awakenings(P<0.05).The satis-faction rate of the patients was remarkably higher(P<0.05)while the incidence of complications significantly lower in the observation group than in the control(P<0.05).Conclusion:Auricular pressure beans combined with Compound Tung-Leaf Burn Oil can ef-fectively alleviate perioperative anxiety,reduce postoperative pain and improve satisfaction of the patients undergoing circumcision.

AIM: To evaluate retinal vascularization caused by the intravitreal injection of Conbercept in the treatment of a series of retinopathy of prematurity(ROP)cases in Type Ⅰ(threshold and pre-threshold period)and aggressive ROP(A-ROP).METHODS: The data of 34 ROP cases(67 eyes)treated by intravitreal injection of Conbercept(IVC)in the ophthalmology department of the Xiamen Children's Hospital from July 2017 to March 2020 were retrospectively analyzed. Reactivation, which refers to recurrence of acute phase features, occurred at any stage of the disease in the presence or absence of other diseases. RESULT: The average gestational age of the 34 children was 28.82±2.32wk. The average birth weight was 1155.18±398.22g. The lesion zone of 19 cases(37 eyes)was Zone Ⅰ. In 10 cases(20 eyes), the lesion was in Zone Ⅱ, and in 5 cases(10 eyes), the lesion was in the posterior Zone Ⅱ. The total effective rate of disease control in ROP children treated with once IVC was 73.1%(49/67), and the vascularization of Zone Ⅱ was completed. The patients showed variable changes in the vascularization in Zone Ⅲ. For the patients who received one treatment and did not reactivate, the average rate of Type Ⅰ vascularization of ROP was 9.11±2.49wk, and the A-ROP was 13.40±4.04wk. The rate of A-ROP vascularization in Zone Ⅱ was significantly longer compared to Type Ⅰ.CONCLUSION: IVC effectively completes vascularization in Zone Ⅱ.

OBJECTIVE: To study the trend of surgical type, surgical procedure and etiological distribution of upper urinary tract repair in recent 10 years. METHODS: The preoperative and perioperative variables and follow-up data of upper urinary tract reconstruction surgery in RECUTTER (Reconstruction of Urinary Tract: Technology, Epidemiology and Result) database from 2010 to 2021 were searched, collected and analyzed. The surgical type, surgical procedure, duration of hospitalization, time of operation, incidence of short-term complications, and proportion of the patients undergoing reoperations were compared between the two groups of 2010-2017 period and 2018-2021 period. RESULTS: A total of 1 072 patients were included in the RECUTTER database. Congenital factors and iatrogenic injuries were the main causes of upper urinary tract repair. Among them, 129 (12.0%) patients had open operation, 403 (37.6%) patients had laparoscopic surgery, 322 (30.0%) patients had robot-assisted laparoscopic surgery and 218 (20.3%) patients had endourological procedure. In the last decade, the total number of surgeries showed a noticeable increasing annual trend and the proportion of robot-assisted laparoscopic surgery in 2018-2021 was significantly higher than that in 2010-2017 (P < 0.001). The 1 072 patients included 124 (11.6%) cases of ileal ureter replacements, 440 (41.1%) cases of pyeloplasty, 229 (21.4%) cases of balloon dilation, 109 (10.2%) cases of ureteral reimplantation, 49 (4.6%) cases of boari flap-Psoas hitch surgery, 60 (5.6%) cases of uretero-ureteral anastomosis, 61 (5.7%) cases of lingual mucosal onlay graft ureteroplasty or appendiceal onlay flap ureteroplasty. Pyeloplasty and balloon dilatation had been the main types of surgery, while the proportion of lingual mucosal onlay graft ureteroplasty plus appendiceal onlay flap ureteroplasty had increased significantly in recent years (P < 0.05). In addition, the time of operation was significantly increased (P < 0.05) after 2018, which was considered to be related to the sharp increase in the proportion of robot-assisted laparoscopic surgery. We found that minimally invasive surgery (endourological procedure and robot-assisted laparoscopic surgery) as an independent risk factor (P=0.050, OR=0.472) could reduce the incidence of short-term post-operative complications. CONCLUSION We have justified the value of the RECUTTER database, created by the Institute of Urology, Peking University in data support for clinical research work, and provided valuable experience for the construction of other multi-center databases at home and abroad. In recent 10 years, we have observed that, in upper urinary tract reconstruction surgery, the surgery type tends to be minimally invasive and the surgery procedure tends to be complicated, suggesting the superiority of robot-assisted laparoscopic surgery.
