Objective To evaluate the long-term efficacy of transjugular intrahepatic portosystemic shunt(TIPS)with bare stents and Fluency covered stents in the treatment of portal hypertension,and to discuss its clinical value.Methods The clinical data of 29 patients with intractable ascites or esophagogastric fundus varices rupture and hemorrhage caused by cirrhotic portal hypertension,who received TIPS with bare stents and covered stents at the First Affiliated Hospital of Xinjiang Medical University of China(25 patients)and the Lishui Municipal Central Hospital of China(4 patients)between August 2012 and December 2017,were retrospectively analyzed.The patients were regularly followed up to check the survival status.The postoperative cumulative shunt patency rate and cumulative survival rate of the patients were analyzed by Kaplan-Meier method.Results The technical success rate of TIPS was 100％.The mean portal vein pressure was decreased from preoperative(40.21±3.24)cmH2O to postoperative(24.55±3.55)cmH2O(P＜0.05).The patients were followed up for 5.1-10.5 years.The postoperative 1-,3-,5-,7-year primary cumulative patency rates of the shunt were 89.7％,75.9％,75.9％ and 52.5％,respectively.The postoperative 5-,7-,9-and 10-year cumulative survival rates were 100％,66.9％,66.9％ and 33.4％,respectively.The incidence of hepatic encephalopathy was 13.8％(4/29).Conclusion Using bare stents combined with Fluency covered stents for TIPS is clinically safe and effective in the treatment of portal hypertension.This technique carries higher long-term shunt patency rate and low incidence of hepatic encephalopathy.Therefore,it can be used as a substitute for Viatorr stent when necessary.(J Intervent Radiol,2024,33:295-299)

Background::There is a need for effective and safe therapies for psoriasis that provide sustained benefits. The aim of this study was to assess the efficacy and safety of tildrakizumab, an anti-interleukin-23p19 monoclonal antibody, for treating moderate-to-severe plaque psoriasis in Chinese patients.Methods::In this multi-center, double-blind, phase III trial, patients with moderate-to-severe plaque psoriasis were enrolled and randomly assigned (1:1) to receive subcutaneous tildrakizumab 100 mg or placebo at weeks 0 and 4. Patients initially assigned to placebo were switched to receive tildrakizumab at weeks 12, 16, and every 12 weeks thereafter. Patients in the tildrakizumab group continued with tildrakizumab at week 16, and every 12 weeks until week 52. The primary endpoint was the Psoriasis Area and Severity Index (PASI 75) response rate at week 12.Results::At week 12, tildrakizumab demonstrated significantly higher PASI 75 response rates (66.4% [73/110] vs. 12.7% [14/110]; difference, 51.4% [95% confidence interval (CI), 40.72, 62.13]; P <0.001) and Physician’s Global Assessment (60.9% [67/110] vs. 10.0% [11/110]; difference, 49.1% [95% CI, 38.64, 59.62]; P <0.001) compared to placebo. PASI 75 response continued to improve over time in both tildrakizumab and placebo-switching to tildrakizumab groups, reaching maximal efficacy after 28 weeks (86.8% [92/106] vs. 82.4% [89/108]) and maintained up to 52 weeks (91.3% [95/104] vs. 87.4% [90/103]). Most treatment-emergent adverse events were mild and not related to tildrakizumab. Conclusion::Tildrakizumab demonstrated durable efficacy through week 52 and was well tolerated in Chinese patients with moderate-to-severe plaque psoriasis.Trial registration::ClinicalTrials.gov, NCT05108766.

Objective To compare the detection rates of X-ray,ultrasound,computed tomography(CT)and cone beam CT(CBCT)for submandibular gland calculi in different positions,and to explore the auxiliary value of 3-dimensional visualization technology in diagnosis and treatment of submandibular gland calculi.Methods The X-ray,ultrasound,CT and CBCT examination data of 113 patients with submandibular gland calculi at General Hospital of Ningxia Medical University from Nov.2014 to Mar.2021 were retrospectively analyzed.The detection rates and overall detection rates of the 4 imaging methods for calculi in different positions were compared.Mimics 19.0 software and CBCT data were used for 3D reconstruction imaging,visually displaying the location,size,morphology,and number of calculi from a visual perspective.Results There was no significant difference in the total detection rate of submandibular gland calculi between CBCT and CT(98.2％[111/113]vs 95.6％[108/113],P＞0.05),but both were significantly higher than that of X-ray(65.5％,74/113)and ultrasound(73.5％,83/113).The detection rates of ultrasound for calculi in the anterior and middle ducts were the lowest(63.6％[21/33]and 72.2％[26/36],respectively),which were significantly different from those of CBCT(97.0％[32/33]and 100.0％[36/36],respectively)and CT(93.9％[31/33]and 97.2％[35/36],respectively)(all P＜0.05).The detection rate of X-ray for calculi in the posterior duct was significantly lower than that of ultrasound,CBCT,and CT(40.9％[18/44]vs 81.8％[36/44],97.7％[43/44],and 95.5％[42/44],all P＜0.01).After CBCT data were imported into Mimics 19.0 software,submandibular gland calculi with different sizes,shapes,or numbers were successfully visualized and reconstructed.The reconstructed image was clear,and anatomical position relationship between the calculi and the mandible was visualized.Conclusion CBCT has good application value in the diagnosis of submandibular gland calculi and can replace traditional CT for the diagnosis of sialolithiasis.Clinically,CBCT examination can be directly performed for accurate diagnosis of calculi in the posterior duct which are not detected by double coincidence diagnosis but are indicated by ultrasound.For calculi in the anterior and middle ducts,X-ray and CBCT are preferred.Visualization technology helps clinical patient education and the development of personalized preoperative treatment plans.

Objective To evaluate the clinical application value of medical tissue glue in the treatment of acute hemoptysis by bronchial arterial embolization(BAE).Methods The clinical data of 78 patients who underwent emergency BAE for hemoptysis were retrospectively collected.Among them,18 patients who underwent embolization with medical tissue glue were selected as a study group,and other 18 patients who underwent embolization with absorbent gelatin sponge particles and spring coil were selected as a control group.The technical success rates,average surgical operation time,average surgical cost,postoperative hemoptysis recur-rence rate,and incidence of adverse reactions of the two groups were compared and analyzed.Results The technical success rates of the two groups were both 100％.There were no statistically significant differences in recurrence rate of postoperative hemoptysis and incidence of adverse reactions between the two groups(P＞0.05).The average surgical operation time of study group and control group were 53.4 min[(53.4±2.2)min]and 65.4 min[(65.4±2.8)min],and the average surgical cost were 3 651 yuan[(3 651±102.7)yuan]and 5 094 yuan[(5 094±136.3)yuan],respectively.Compared with the control group,the average surgical operation time and aver-age surgical cost of the study group were shorter,and the differences were statistically significant(P＜0.05).Conclusion Compared with absorbent gelatin sponge particles combined with spring coil embolization,the use of medical tissue glue for embolization is also safe and effective in the treatment of acute hemoptysis patients by BAE.The average surgical operation time is shorter,and the surgical cost for patients is lower.It is worth promoting in clinical practice.

Objective:To investigate the application effect of the comprehensive innovative teaching model with "3D printed model combined with visual surgical simulation" as the core in the clinical teaching of extremity bone defects.Methods:The physicians who participated in the clinical management of patients with extremity bone defects in Department of Orthopedics, Peking University Third Hospital, from March 2019 to December 2021 were selected as subjects and were divided into standardized training group with 52 physicians and refresher physician group with 58 physicians. Teaching and training was performed for the special disease of extremity bone defects, including basic knowledge teaching, dressing change for infected wounds, multidisciplinary discussion, digital surgical simulation, and practical surgical operation. The assessment indices for teaching quality included the assessment of theoretical knowledge and clinical skills, the objective evaluation of the clinical ability of patient management, and an investigation of the degree of satisfaction. SPSS 22.0 was used for the t-test and the chi-square test. Results:After training, both groups had significant increases in the assessment scores of theoretical knowledge [(32.4±6.7）and (42.2±3.8)] and clinical practice skills [(19.6±2.0), (20.8±2.2), (20.5±2.5), (21.5±2.3)]( P<0.05). After training, the standardized training group had significant increases in the scores of six objective evaluation indicators [(8.3±0.8) vs. (6.9±1.1), (7.4±0.7) vs. (6.3±1.5), (7.2±1.3) vs. (5.0±1.4), (7.9±1.2) vs. (4.0±1.5), (8.4±0.8) vs. (6.4±1.6), (40.3±2.6) vs. (28.6±2.4)]( P<0.01), while the refresher physician group had significant improvements in four aspects, i.e., the understanding of extremity bone defects [(8.1±0.9) vs. (7.2±1.1)], the self-confidence in facing complex extremity bone defects [(8.1±1.2) vs. (6.6±0.9)], spatial thinking ability in repair surgery for bone defects [(8.6±0.8) vs. (7.3±0.9)], and overall clinical performance in actual management of patients with bone defects [(41.4±2.3) vs. (37.3±1.8)] ( P<0.01). The satisfaction score for this comprehensive innovative teaching model was (95.3±3.2) points in the standardized training group and (94.8±2.8) points in the refresher physician group. Conclusions:The comprehensive innovative teaching model with "3D printed model combined with visual surgical simulation" as the core can significantly improve the basic knowledge and clinical skills of physicians in a short period of time and meet the needs for learning surgical techniques and advanced diagnosis and treatment concepts among refresher physicians.

Objective:To investigate the effects of the "TECK" (theoretical class, experimental course, case discussion, and knowledge reinforcement) teaching model oriented by post competency in clinical pathology internship teaching.Methods:The intern students from 2015 to 2019 in the pathology direction of clinical medicine in the School of Pathology, Qiqihar Medical College, who were enrolled in the internship from 2019 to 2023, were selected as the research objects.We enrolled 32 medical students from grades 2017, 2018, and 2019 (research group) and 24 medical students from grades 2015 and 2016 (control group) who would participate in pathology internships. The control group adopted the traditional internship mode, while the research group adopted the competency-oriented "TECK" teaching mode. After the internship, the two groups were compared for internship assessment score and surveyed for post competency. With the use of SPSS 18.0 statistical software. Continuous data were presented as (mean±standard deviation) and t-test was used for comparison between groups. Count data were expressed in the number of cases, and chi-square test was used for comparison between groups.The significance level α was 0.05. Results:The research group showed significantly higher scores of skill assessment (82.81±4.20 vs. 79.58±5.09) and pathological diagnosis assessment (80.28±4.23 vs. 76.21±4.58) than the control group (both P<0.05), with no significant difference in the score of theoretical knowledge ( P>0.05). In terms of post competency, the research group was superior to the control group in clinical skills and medical care ability (12.38±0.94 vs. 11.35±0.76), disease prevention and health promotion ability (6.28±0.92 vs. 4.48±0.93), interpersonal communication and information management ability (19.81±1.09 vs. 17.00±1.28), and teamwork and scientific research ability (11.44±1.27 vs. 9.25±0.87; all P<0.05). There were no significant differences between the two groups in core values and professional literacy and medical knowledge and lifelong learning (both P>0.05). Conclusions:In undergraduate internships, the competency-oriented "TECK"teaching mode can significantly improve students' clinical operation and pathological diagnosis ability, and effectively cultivate their abilities of clinical skills and medical care, disease prevention and health promotion, interpersonal communication and information management, teamwork and scientific research.

BACKGROUND: Significant brain volume deviation is an essential phenotype in children with neurodevelopmental delay (NDD), but its genetic basis has not been fully characterized. This study attempted to analyze the genetic factors associated with significant whole-brain deviation volume (WBDV). METHODS: We established a reference curve based on 4222 subjects ranging in age from the first postnatal day to 18 years. We recruited only NDD patients without acquired etiologies or positive genetic results. Cranial magnetic resonance imaging (MRI) and clinical exome sequencing (2742 genes) data were acquired. A genetic burden test was performed, and the results were compared between patients with and without significant WBDV. Literature review analyses and BrainSpan analysis based on the human brain developmental transcriptome were performed to detect the potential role of genetic risk factors in human brain development. RESULTS: We recruited a total of 253 NDD patients. Among them, 26 had significantly decreased WBDV (<-2 standard deviations [SDs]), and 14 had significantly increased WBDV (>+2 SDs). NDD patients with significant WBDV had higher rates of motor development delay (49.8% [106/213] vs . 75.0% [30/40], P  = 0.003) than patients without significant WBDV. Genetic burden analyses found 30 genes with an increased allele frequency of rare variants in patients with significant WBDV. Analyses of the literature further demonstrated that these genes were not randomly identified: burden genes were more related to the brain development than background genes ( P  = 1.656e -9 ). In seven human brain regions related to motor development, we observed burden genes had higher expression before 37-week gestational age than postnatal stages. Functional analyses found that burden genes were enriched in embryonic brain development, with positive regulation of synaptic growth at the neuromuscular junction, positive regulation of deoxyribonucleic acid templated transcription, and response to hormone, and these genes were shown to be expressed in neural progenitors. Based on single cell sequencing analyses, we found TUBB2B gene had elevated expression levels in neural progenitor cells, interneuron, and excitatory neuron and SOX15 had high expression in interneuron and excitatory neuron. CONCLUSION Idiopathic NDD patients with significant brain volume changes detected by MRI had an increased prevalence of motor development delay, which could be explained by the genetic differences characterized herein.

BACKGROUND: Previous research demonstrated that a homozygous mutation of g.136372044G>A (S12N) in caspase recruitment domain family member 9 ( CARD9 ) is critical for producing Aspergillus fumigatus -induced ( Af -induced) T helper 2 (T H 2)-mediated responses in allergic bronchopulmonary aspergillosis (ABPA). However, it remains unclear whether the CARD9S12N mutation, especially the heterozygous occurrence, predisposes the host to ABPA. METHODS: A total of 61 ABPA patients and 264 controls (including 156 healthy controls and 108 asthma patients) were recruited for sequencing the CARD9 locus to clarify whether patients with this heterozygous single-nucleotide polymorphisms are predisposed to the development of ABPA. A series of in vivo and in vitro experiments, such as quantitative real-time polymerase chain reaction, flow cytometry, and RNA isolation and quantification, were used to illuminate the involved mechanism of the disease. RESULTS: The presence of the p.S12N mutation was associated with a significant risk of ABPA in ABPA patients when compared with healthy controls and asthma patients, regardless of Aspergillus sensitivity. Relative to healthy controls without relevant allergies, the mutation of p.S12N was associated with a significant risk of ABPA (OR: 2.69 and 4.17 for GA and AA genotypes, P = 0.003 and 0.029, respectively). Compared with patients with asthma, ABPA patients had a significantly higher heterozygous mutation (GA genotype), indicating that p.S12N might be a significant ABPA-susceptibility locus ( aspergillus sensitized asthma: OR: 3.02, P = 0.009; aspergillus unsensitized asthma: OR: 2.94, P = 0.005). The mutant allele was preferentially expressed in ABPA patients with heterozygous CARD9S12N , which contributes to its functional alterations to facilitate Af -induced T H 2-mediated ABPA development. In terms of mechanism, Card9 wild-type ( Card9WT ) expression levels decreased significantly due to Af -induced decay of its messenger RNA compared to the heterozygous Card9S12N . In addition, ABPA patients with heterozygous CARD9S12N had increased Af -induced interleukin-5 production. CONCLUSION Our study provides the genetic evidence showing that the heterozygous mutation of CARD9S12N , followed by allele expression imbalance of CARD9S12N , facilitates the development of ABPA.

Objective:To characterize the injuries suffered by athletes in snow events other than alpine skiing in the Zhangjiakou Zone of the Olympic Winter Games Beijing 2022, in order to provide insights for prevention of sports injuries and preparation of large-scale winter sports events.Methods:The medical records were retrospectively collected of all athletes who had been treated at Beijing University Third Hospital Chongli within the closed loop of the Zhangjiakou Zone during the Winter Olympics and Paralympics (from November 21, 2021 to April 5, 2022). The incidence, severity and part of the injuries were analyzed, as well as the medical treatment process.Results:In the Zhangjiakou Zone, a total of 1,188 athletes participated in the Winter Olympic Games, with an injury incidence of 2.9% (34/1,188), while 420 ones participated in the Winter Paralympic Games, with an injury incidence of 1.7% (7/420). The average daily medical visits were the highest during the Winter Olympics phase (1.16 visits per day), and their emergency severity index (ESI) ranged from level 3 to level 4. The department of orthopedics was visited the most (92.7%, 38/41). Lower limb injuries accounted for the highest proportion (53.7%, 22/41), with the knee ones accounting for 36.6% (15/41) of all injuries. Most of the athletes with ESI level 3 received splint fixation (62.5%, 5/8), while those with ESI level 4 mostly received observation and follow-up (57.6%, 19/33). A total of 57 radiological examinations were performed in the 41 athletes. X-ray was used the most frequently on a single day (5.00 times) while magnetic resonance imaging was per day on average (0.16 times). The transfer time for the athletes injured was (27.4±8.8) min which was not influenced by the 4 weather conditions (cloudy, sunny, light snow, and cloudy) ( P=0.374). Conclusions:The incidence of injuries during the Beijing Winter Olympics in the Zhangjiakou Zone was lower than that in other areas of the Beijing Winter Olympics and in previous Winter Olympics. There were no serious life-threatening cases. The imaging examination resources and transfer speed in the Zhangjiakou Zone were able to meet the medical needs of athletes at all stages of the Beijing Winter Olympics and Paralympics. Athletes should pay attention to protection of their lower limbs during skiing competitions.
