Objective To explore the value of oral contrast-enhanced ultrasonography (OCEUS) combined with contrast-enhanced CT in predicting preoperative T staging in patients with gastric cancer. Methods A retrospective analysis was conducted on 80 patients with gastric cancer confirmed via endoscopic biopsy or postoperative pathology at the First People’s Hospital of Jining from January 2021 to November 2024. The cohort included 56 males and 24 females, aged 38-79 years, with a median age of 55.9 years. All patients underwent both OCEUS and contrast-enhanced CT within one week prior to surgery. T staging of gastric cancer was determined using OCEUS, contrast-enhanced CT, or their combination. The results were compared with pathological T staging, and statistical differences in accuracy were analyzed. Results Pathological T staging identified T1 in 9 cases, T2 in 16 cases, T3 in 42 cases, and T4 in 13 cases. OCEUS indicated T1 in 6 cases, T2 in 14 cases, T3 in 50 cases, and T4 in 10 cases, with an accuracy rate of 80.0%. Contrast-enhanced CT indicated T1 in 4 cases, T2 in 12 cases, T3 in 52 cases, and T4 in 12 cases, with an accuracy rate of 75.0%. The combination of OCEUS and contrast-enhanced CT indicated T1 in 6 cases, T2 in 15 cases, T3 in 47 cases, and T4 in 12 cases, with an accuracy rate of 87.5%. The combined approach demonstrated significantly higher accuracy in preoperative T staging compared to either method alone (P < 0.05). Conclusion The combination of OCEUS and contrast-enhanced CT improves the accuracy of preoperative T staging in gastric cancer patients, providing valuable support for their diagnosis and treatment.

【Objective】 To develop a clinical prediction model based on ⁶⁸Ga-prostate-specific membrane antigen-11 (⁶⁸Ga-PSMA-11), positron emission tomography/computed tomography (PET/CT) and multiparametric magnetic resonance imaging (mpMRI) parameters to stratify prostate cancer patients undergoing targeted biopsy, so as to avoid unnecessary systematic biopsy. 【Methods】 A total of 96 clinically significant prostate cancer (csPCa) patients who underwent ⁶⁸Ga-PSMA-11 PET/CT and mpMRI prior to prostate targeted biopsy with systematic biopsy during Jan.2020 and Feb.2023 in Nanjing Drum Tower Hospital were retrospectively analyzed.By univariate and multivariate logistic regression analyses, maximum standard uptake value (SUVmax) in ⁶⁸Ga-PSMA-11 PET/CT and minimum apparent diffusion coefficien (ADCmin) in mpMRI, as well as clinical parameters were evaluated to identify the independent predictors correlative with the effective diagnosis of targeted biopsy, and a clinical prediction model was constructed. 【Results】 Multivariate logistic regression analysis showed that SUVmax (OR=0.878, 95%CI: 0.804-0.959, P=0.004) and ADCmin (OR=1.005, 95%CI:1.001-1.010, P=0.027) were independent predictors of the effective diagnosis of targeted biopsy alone.The sensitivity, specificity, accuracy and area under the receiver operator characteristic curve (AUC) of the model were 0.80, 0.80, 0.83 and 0.84, respectively. 【Conclusion】 The clinical prediction model based on ⁶⁸Ga-PSMA-11 PET/CT and mpMRI parameters is helpful to improve the effective diagnosis of targeted biopsy alone, and has practical value to stratify patients with csPCa so as to safely avoid systematic biopsy and effectively balance the benefits and risks.

Objective:To evaluate the diagnostic value of targeted biopsy of secondary lesion (SL) in systematic biopsy (SB) combined targeted biopsy for clinically significant prostate cancer (CsPCa).Methods:A retrospective analysis was conducted on the data of patients who underwent systematic biopsy combined target biopsy at Nanjing Drum Tower Hospital from January 2021 to February 2023, and they had at least two Prostate Imaging-Reporting and Data System (PI-RADS) score ≥3 lesions on prostate magnetic resonance imaging. The study included patients with a median age of 70 (65, 76) years old, median prostate specific antigen (PSA) was 9.1 (5.96, 13.62) ng/ml, median prostate volume was 39.1 (29.27, 53.25) ml, and median PSAD was 0.2 (0.15, 0.38) ng/ml 2.The index lesion (IL) was defined as the one with the highest PI-RADS score and SL was defined as the one with the second-highest PI-RADS score. If the two lesions had the same PI-RADS score, the one with larger maximum diameter was IL and the other one was SL. The median maximum diameter of IL and SL were 1.3 (1.06, 1.66) cm and 0.9 (0.69, 1.20) cm, respectively. The median maximum diameter ratio of IL and SL was 1.48 (1.10, 1.91), and the median maximum diameter difference of IL and SL was 0.9 (0.20, 1.89) cm. The IL in peripheral zone was found in 238 patients (62.63%) and SL in peripheral zone was found in 255 patients (67.10%). There were 204 patients (53.68%) having both IL and SL on the same side of prostate. According to the combination of PI-RADS scores of IL and SL, patients were categorized into various groups: 96 patients (25.26%) with IL3 and SL3, 79 (20.78%) with IL4 and SL3, 98 (25.78%) with IL4 and SL4, 21 (5.52%) with IL5 and SL3, 76 (20.0%) with IL5 and SL4, and 10 (2.63%) with IL5 and SL5. Targeted biopsy was performed on at least two of the most significant lesions. Comparison was performed in the detection rate of CsPCa between SB+ IL+ SL and SB+ IL (SL was omitted). To explore the factors influencing the detection rate of CsPCa, a multivariate logistic regression analysis was used. Results:The detection rate of CsPCa in this study was 78.95% (300/380) based on SB+ IL+ SL. After omitting SL target biopsy, the detection rate of CsPCa was 78.16% (297/380, P>0.05) under the condition of SB+ IL. No significant differences were noted between the two groups. The multivariate logistic regression analysis showed that PSA ( OR=1.11, 95% CI 1.05-1.20, P<0.01), prostate volume ( OR=0.98, 95% CI 0.96-0.99, P<0.01), SL maximum diameter ( OR=0.19, 95% CI 0.08-0.50, P<0.01), ratio of IL and SL maximum diameter ( OR=0.34, 95% CI 0.16-0.68, P<0.01), difference of IL and SL maximum diameter ( OR=1.50, 95% CI 1.10-2.29, P<0.05), and PI-RADS score group of IL and SL (IL3 vs. SL3 as the reference, IL4 vs. SL3 OR=4.79, 95% CI 2.21-10.91, P<0.01, IL4 vs. SL4 OR=23.11 95% CI 8.09-85.28, P<0.01, IL5 vs. SL3/4/5 OR=15.28 95% CI 5.21-48.55, P<0.01) were the influencing factors for detection rate of CsPCa. Conclusions:For patients with at least two PI-RADS score≥3 lesions on prostate magnetic resonance imaging, omitting SL can almost maintain the same detection efficacy.

[Objective] To investigate the pathological characteristics of false-positive lesions of prostate cancer on ⁶⁸Ga-PSMA-11 PET/CT based on the pathology of whole mount specimens, in order to more accurately assess the degree of malignancy within the prostate tissue and avoid overdiagnosis and unnecessary treatment. [Methods] A total of 77 patients who underwent ⁶⁸Ga-PSMA-11 PET/CT before radical prostatectomy in Nanjing Drum Tower Hospital during Jan.2018 and Dec.2022 were retrospectively analyzed.The pathology of whole mount specimens was detected.Two nuclear physicians examined all imaging plates without knowing the pathological results.Two pathological physicians completed all pathological diagnosis without knowing the imaging results.The pathological characteristics of false-positive lesions were determined by matching ⁶⁸Ga-PSMA-11 PET/CT and pathological specimens.To analyze the pathological features of false-positive lesions, true-negative lesions were randomly delineated and defined.The pathological features of false-positive and true-negative lesions were analyzed and compared using Fisher exact test. [Results] After the imaging and pathological sections were matched, 21(16.3%) false-positive lesions were identified.The pathological characteristics of the 21 false-positive lesions were as follows: 16 (76.2%) simple atrophy with cyst formation, 3(14.3%) prostatic nodular hyperplasia, and 2(9.5%) inflammation.The pathological characteristics of 21 true-negative lesions were: 13(61.9%) normal glands, 5(23.8%) prostatic nodular hyperplasia and 3(14.3%) simple atrophy with cyst formation.Fisher exact test showed that the proportion of simple atrophy with cyst formation in the pathological features of false-positive lesions and true-negative lesions was statistically significant (76.2% vs.14.3%, P<0.001). [Conclusion] Simple atrophy with cyst formation may be a characteristic pathological type of the false-positive lesions of prostate cancer on ⁶⁸Ga-PSMA-11 PET/CT.

OBJECTIVE To evaluate the effectiveness， safety， economy， innovation， suitability and accessibility of recombinant Mycobacterium tuberculosis fusion protein （EC）， and to provide evidence for selecting skin detection methods for tuberculosis infection diagnosis and auxiliary diagnosis of tuberculosis. METHODS The effectiveness and safety of EC compared with purified protein derivative of tuberculin （TB-PPD） were analyzed by the method of systematic review. Cost minimization analysis， cost-effectiveness analysis and cost-utility analysis were used to evaluate the short-term economy of EC compared with TB-PPD， and cost-utility analysis was used to evaluate the long-term economy. The evaluation dimensions of innovation， suitability and accessibility were determined by systematic review and improved Delphi expert consultation， and the comprehensive score of EC and TB-PPD in each dimension were calculated by the weight of each indicator. RESULTS The scores of effectiveness， safety， economy， innovation and suitability of EC were all higher than those of TB-PPD. The affordability scores of the two drugs were consistent， while the availability score of EC was lower than those of TB-PPD. After considering dimensions and index weight， the scores of effectiveness， safety， economy， innovation， suitability， accessibility and the comprehensive score of EC were all higher than those of TB-PPD. CONCLUSIONS Compared with TB-PPD， EC performs better in all dimensions of effectiveness， safety， economy， innovation， suitability and accessibility. However， it is worth noting that EC should further improve its availability in the dimension of accessibility.

OBJECTIVE: To explore the clinical phenotype and genetic variant in a child with Verheij syndrome (VRJS). METHODS: A child who had presented at the Soochow University Affiliated Children's Hospital and Wujiang District Children's Hospital in July 2022 for "elevated scapula since early childhood" was selected as the study subject. Peripheral blood samples of the child and his parents were collected and subjected to whole exome sequencing. Candidate variant was verified by Sanger sequencing and bioinformatic analysis. RESULTS: The child had manifested elevated scapulae, torticollis, neck asymmetry, facial dysmorphism, dispersed café-au-lait spots, limited mobility of upper limbs and shoulder joints, and intellectual disability. Sequencing revealed that he has harbored a de novo heterozygous c.405dupT (p.Ile136Tyrfs*4) variant of the PUF60 gene. Based on the guidelines from the American College of Medical Genetics and Genomics (ACMG), this variant was classified as pathogenic (PVS1+PS2_moderate+PM2_supporting). Combined his clinical features and result of genetic testing, the child was diagnosed with VRJS due to variant of the PUF60 gene. CONCLUSION The clinical manifestations of VRJS include facial dysmorphism, intellectual disability, elevated scapulae, vertebral fusion, other skeletal malformations, without significant abnormalities of the heart, kidney, and eyes, which need to be distinguished from Klippel-Feil syndrome. Above finding has expended the mutation spectrum of the PUF60 gene and provided a reference for delineation of the genotype-phenotype correlation of the VRJS.

Objective:To investigate the safety and efficacy of modified Retzius-sparing robot-assisted laparoscopic radical prostatectomy for localized transitional zone prostate cancer.Methods:From May 2019 to February 2021, the clinical data of 284 patients with transitional zone(TZ) prostate cancer was retrospectively analyzed. Among them, 91 cases underwent modified Retzius-sparing robot-assisted laparoscopic radical prostatectomy(modified RS-RARP), and 193 cases underwent conventional robot-assisted laparoscopic radical prostatectomy (RARP). The Retzius space was directly entered during modified RS-RARP.The mean age of modified RS-RARP group and conventional RARP group was (67.8±9.1) years old and (69.5±8.4) years old, respectively. BMI of the two groups was (21.57±2.25)kg/m 2 and (21.8±1.8)kg/m 2 respectively; prostate volume was (31.2±13.5)ml and (29.3±12.9)ml respectively; preoperative PSA of the two groups were (10.2±6.1)ng/ml and (9.3±5.8)ng/ml respectively; and there was no significant difference in the above mentioned data( P>0.05). For Gleason score, there were 8 cases of score 6, 74 cases of score 7, 9 cases of score 8 in modified RS-RARP group and 21 cases of score 6, 153 cases of score 7, 19 cases of score 8 in conventional RARP group. For Clinical stage, there were 11 cases of T 1 stage, 80 cases of T 2 stage in modified RS-RARP group, and 20 cases of T 1 stage, 173 cases of T 2 stage in conventional RARP group. There was no significant difference in the above mentioned data( P>0.05). The operation time, intraoperative blood loss, ratio of transfusion, incidence of complication, positive rate of surgical margin and recovery of urinary continence were compared. Results:All 284 cases of surgery were completed. The operative time of modified RS-RARP was (89.2±10.1) minutes, which was significantly less than that of conventional RARP group[(100.5±12.3)min]. The intraoperative blood loss of the two groups was (245.0±50.0) ml and (250.0±50.0) ml respectively. The number of positive surgical margin was 14(15.4%) and 33(17.1%) respectively. There was no significant difference between the two groupsfor the above mentioned parameters( P>0.05). The ratio of urinary continence recovery in the modified RS-RARP group within 1 month was 49.45%, which was significantly higher than that of conventional RARP group (31.09%)( P<0.05). Conclusions:Compared with conventional RARP, modified RS-RARP might shorten the operation time and help the recovery of urinary continence for patients with TZ prostate cancer.
