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.

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 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)

Objective:The transjugular or transfemoral approach is used as a common method for hepatic venous pressure gradient (HVPG) measurement in current practice. This study aims to confirm the safety and effectiveness of measuring HVPG via the forearm venous approach.Methods:Prospective recruitment was conducted for patients with cirrhosis who underwent HVPG measurement via the forearm venous approach at six hospitals in China and Japan from September 2020 to December 2020. Patients' clinical baseline information and HVPG measurement data were collected. The right median cubital vein or basilic vein approach for all enrolled patients was selected. The HVPG standard process was used to measure pressure. Research data were analyzed using SPSS 22.0 statistical software. Quantitative data were used to represent medians (interquartile ranges), while qualitative data were used to represent frequency and rates. The correlation between two sets of data was analyzed using Pearson correlation analysis.Results:A total of 43 cases were enrolled in this study. Of these, 41 (95.3%) successfully underwent HVPG measurement via the forearm venous approach. None of the patients had any serious complications. The median operation time for HVPG detection via forearm vein was 18.0 minutes (12.3~38.8 minutes). This study confirmed that HVPG was positively closely related to Child-Pugh score ( r = 0.47, P = 0.002), albumin-bilirubin score ( r = 0.37, P = 0.001), Lok index ( r = 0.36, P = 0.02), liver stiffness ( r = 0.58, P = 0.01), and spleen stiffness ( r = 0.77, P = 0.01), while negatively correlated with albumin ( r = -0.42, P = 0.006). Conclusion:The results of this multi-centre retrospective study suggest that HVPG measurement via the forearm venous approach is safe and feasible.

Objective:To analyze the results of the practice test and formal test of the annual professional proficiency test for residents in 2022, to investigate related influencing factors and the effectiveness of the practice test, and to propose the measures for improving the results of the annual professional proficiency test.Methods:The scores of the annual professional proficiency test were analyzed for 202 residents who participated in the test in 2022, and the data on sex, education background, type of personnel, whether they passed the medical licensing examination, and practice test scores were analyzed to investigate related influencing factors. SPSS 23.0 and GraphPad Prism 8 were used for the chi-square test, the t-test, the one-way of variance, and the Fisher's exact test. A multiple linear regression analysis was used to identify influencing factors, and a Pearson correlation analysis was also performed. Results:The scores of the annual professional proficiency test for 202 residents were normally distributed with the highest number of the residents with a score of 90-99 points and the lowest number of the residents with a score of <70 points. The residents who passed the medical licensing examination had a significantly higher score of the annual professional proficiency test than those who failed the examination ( t=2.87, P=0.005), and the residents who passed the three practice tests had a significantly higher score of the annual professional proficiency test than those who failed the practice tests ( P<0.05). The score of the second practice test, the score of the third practice test, and the passing of medical licensing examination were independent influencing factors for the score of annual professional proficiency test ( R2=0.236, R2=0.201, F=6.60, P<0.05). The correlation analysis showed that the scores of the three practice tests were positively correlated with the final score ( r=0.189, 0.373, and 0.311, P<0.05). Conclusions:Improving the passing rate of medical licensing examination and strengthening pre-examination practice tests can help to improve the score of annual professional proficiency test. At the same time, it is necessary to improve the quality of training through the measures such as strengthening the homogenization management of different types of students, improving the attention and enthusiasm of all levels, and accelerating the construction of question banks.

Objective:To comparae the accuracy of imaging examination in preoperative parathyroid localization, and the safety and effect of total parathyroidectomy on secondary hyperparathyroidism complicated by chronic renal failure.Method:A total of 257 patients with secondary hyperparathyroidism who underwent total parathyroidectomy at the Department of General Surgery , Zhongshan Hospital, Dalian University from Mar 2012 to Mar 2022 were analyzed retrospectively.Result:Six hundred fourty parathyroid glands were found by color Doppler ultrasound and 954 parathyroid glands were by enhanced CT before the operation. Among them, the number of patients with accurate location of all 4 parathyroid glands by color Doppler ultrasound was 54, while that by enhanced CT was 216. The parathyroid detection rate by enhanced CT was significantly higher than that of color Doppler ultrasound ( χ2=325.480, P<0.001), and the accuracy rate was significantly higher tnan that of color ultrasound ( χ2=215.146, P<0.001). The average values of iPTH before operation, on the day after operation, on the 1st day and 7th day after operation were (1 880±890), (137±82), (66±46) and (34±23) pg/ml, respectively. The clinical symptoms of all patients were significantly relieved. Conclusions:Enhanced CT is superior to color Doppler ultrasound in the overall detection rate and individual localization accuracy of preoperative parathyroid localization. Total parathyroidectomy is safe and reliable in the treatment of secondary hyperparathyroidism complicated by chronic renal failure.

OBJECTIVE: To summarize the clinical features and biological characteristics of Helsmoortel Van der Aa syndrome (HVDAS) due to hotspot mutations of the ADNP gene in order to facilitate early diagnosis. METHODS: Clinical data and result of genetic testing for a girl with HVDAS due to hotspot mutation of the ADNP gene was summarized. Related literature was also reviewed. RESULTS: The patient, a 2-year-old girl, had presented with growth retardation, facial dysmorphism, psychomotor and language delay and recurrent respiratory infections. Whole exome sequencing revealed that she has harbored a heterozygous c.2496_2499delTAAA (p.Asn832Lysfs*81) variant of the ADNP gene, which was not found in either of her parents. CONCLUSION Although the typical features of the HVDAS have included intellectual disability and autism spectrum disorders, growth retardation and premature primary tooth eruption may also be present. In addition, the phenotypic difference among individuals carrying hot spot variants of the ADNP gene was not prominent.

Purpose: Mixed-lineage leukemia protein 4 (MLL4/KMT2D) is a histone methyltransferase, and its mutation has been reported to be associated with a poor prognosis in many cancers, including lung cancer. We investigated the function of MLL4 in lung carcinogenesis. Materials and Methods: RNA sequencing (RNA-seq) in A549 cells transfected with control siRNA or MLL4 siRNA was performed. Also, we used EdU incorporation assay, colony formation assays, growth curve analysis, transwell invasion assays, immunohistochemical staining, and in vivo bioluminescence assay to investigate the function of MLL4 in lung carcinogenesis. Results: We found that MLL4 expression was downregulated in non–small cell lung cancer (NSCLC) tissues compared to adjacent normal tissues and tended to decrease with disease stage progression. We analyzed the transcriptomes in control and MLL4- deficient cells using high-throughput RNA deep sequencing (RNA-seq) and identified a cohort of target genes, such as SOX2, ATF1, FOXP4, PIK3IP1, SIRT4, TENT5B, and LFNG, some of which are related to proliferation and metastasis. Our results showed that low expression of MLL4 promotes NSCLC cell proliferation and metastasis and is required for the maintenance of NSCLC stem cell properties. Conclusion Our findings identify an important role of MLL4 in lung carcinogenesis through transcriptional regulation of PIK3IP1, affecting the PI3K/AKT/SOX2 axis, and suggest that MLL4 could be a potential prognostic indicator and target for NSCLC therapy.

Population bioequivalence (PBE) is a statistical approach recommended by FDA to evaluate the consistency of particle size distribution of numerous nanoparticle products.However, when particle size distribution (PSD) profile exhibits multiple peaks or other complex distributions, the traditional descriptors D50 and SPAN are no longer suitable to describe PSD.Earth mover''s distance (EMD) is a new statistical metric for assessing the difference between distributions.In this study, we used EMD to measure the discrepancy between PSD and then PBE was applied to perform statistical test to establish equivalence.Our results showed that the proposed method can effectively reject an unequivalent product and pass an equivalent product, thus indicating its helpfulness in guiding the optimization of formulation and preparation process.

Objective:To investigate the differences of integral alpha 3 (ITGA3) mRNA and protein expressions in gliomas of different grades and different cell lines, and gliomas tissues of different clinical and molecular characteristics, and evaluate their prognostic values in brain glioma patients.Methods:(1) ITGA3 mRNA expression data in the brain gliomas and clinical data of these glioma patients were obtained from The Cancer Genome Atlas (TCGA) and Chinese Glioma Genome Atlas (CGGA). The differences of ITGA3 mRNA expressions in glioma patients with different gender, ages, WHO grading, isocitrate dehydrogenase 1 ( IDH) mutation statuses, and 1p/19q co-deletion statuses were compared. Kaplan-Meier method was used to plot and compare the survival curves of patients with ITGA3 mRNA high expression and ITGA3 mRNA low expression. Receiver operating characteristic (ROC) curve was used to analyze the predictive efficiency of ITGA3 mRNA expression in survival rate of gliomas. Univariate and multivariate Cox regression analyses were used to explore the independent influencing factors for prognoses in glioma patients. The independent influencing factors for prognosis were used to construct nomograms and the calibration diagram was used to verify the reliability of nomograms in predicting the prognoses of these patients. (2) Intracellular localization of ITGA3 and ITGA3 protein expression in low- and high-grade gliomas were determined by on-line database of Human Protein Atlas (HPA). (3) Brain glioma cells U87, U118, U251 and human astrocytes SVG were cultured in vitro, and the ITGA3 mRNA and protein expressions in cells were detected by Western blotting and reverse transcription (RT)-PCR, respectively. Results:(1) In TCGA database, the ITGA3 mRNA expressions in gliomas of WHO grading II, III and IV increased successively, with significant differences (P<0.05). In CGGA database, the ITGA3 mRNA expression in glioma of WHO grading IV was statistically higher than that in glioma of WHO grading II and III ( P<0.05). In TCGA and CGGA databases, the ITGA3 mRNA expressions in glioma patients aged ≤40 years and >40 years, patients with IDH wild-type and IDH mutation, and patients with chromosome 1p/19q deletion and chromosome 1p/19q non-deletion were statistically different ( P<0.05). The survival rate of patients with low ITGA3 mRNA expression was significantly higher than that of patients with high ITGA3 mRNA expression, no matter in low-grade glioma, glioblastoma, or entire glioma samples ( P<0.05). ROC curve showed that, in TCGA database, the area under the curve (AUC) of ITGA3 mRNA in predicting 1, 3, and 5 years survival was 0.791, 0.786, and 0.708 in glioma patients; in CGGA database, the AUC of ITGA3 mRNA in predicting 1, 3, and 5 years survival was 0.661, 0.667, and 0.659. Multivariate Cox regression analysis showed that, in TCGA database, age, WHO grading, IDH mutation, chromosome 1p/19q deletion and ITGA3 mRNA expression ( HR=1.018, 95%CI: 1.006-1.030, P=0.0.003) were independent influencing factors for prognoses of glioma patients ( P<0.05); and in CGGA database, WHO grading, IDH mutation, chromosome 1p/19q deletion, and ITGA3 mRNA expression ( HR=1.445, 95%CI: 1.132-1.844, P=0.003) were independent influencing factors for prognoses of glioma patients ( P<0.05). Nomograms showed that age had the greatest influence in survival, followed by ITGA3 mRNA expression. Calibration plots showed that nomogram was reliable in predicting 1-, 3-, and 5-year survival in glioma patients. (2) Immunofluorescence localization showed that ITGA3 protein mainly aggregated in cell membrane and vesicles. Immunohistochemical staining showed that the ITGA3 protein expression in high-grade glioma tissues was obviously higher than that in low-grade glioma tissues. (3) The results of RT-PCR and Western blotting revealed that the ITGA3 mRNA and protein expressions in glioma cell lines U87, U118 and U251 were significantly higher than those in SVG cells ( P<0.05). Conclusion:The ITGA3 mRNA and protein expression levels are correlated with the malignant degrees of glioma; patients with ITGA3 mRNA low expression tend to have a high overall survival; ITGA3 mRNA expression can be used as an index to evaluate the prognoses of glioma patients.
