Objective: To verify by retrospective analysis the performance of applying dual-parametric (T2 weighted image [T2WI] and diffusion weighted image [DWI]) and multi-parametric (T2WI, DWI, and dynamic contrast enhance [DCE]) evaluation systems of Vesical Imaging-Reporting and Data System (VI-RADS) in the magnetic resonance imaging (MRI) diagnosis of bladder cancer.
Methods: The imaging and clinical data of bladder cancer patients who underwent bladder MRI examination in the Department of Urology of our hospital between January 2020 and December 2021 were collected. A total of 215 bladder cancer patients, among whom there were 183 males and 32 females with an average age of (67.60±11.42) years, were included. The bladder cancer diagnosis of all the cases was verified by pathology analysis of tissue samples. Two radiologists, who were double-blinded, scored multiple sequences separately. Then, a comparative analysis was made on the diagnostic performance of dual-parametric and multi-parametric VI-RADS diagnostic scores. The diagnostic test with receiver operator characteristic (ROC) curves and Cohen's Kappa were used to evaluate the diagnostic efficacy and consistency.
Results: The area under the curve (AUC) and 95% confidence interval (CI) of the multi-parametric VI-RADS evaluation system by the two radiologists in the overall population were 0.878 (0.830-0.925) and 0.856 (0.805-0.907), while those for the bi-parametric VI-RADS evaluation system were 0.889 (0.844-0.934) and 0.856 (0.805-0.907), showing no statistically significant difference. No significant difference was observed in the subgroup analysis of patients who underwent transurethral resection of bladder tumor (TURBT). Furthermore, the Kappa values for inter-rater agreement between of the two radiologists were 0.694 and 0.546 (with the VI-RADS score≥3 defined as being positive) and 0.693 and 0.712 (with the VI-RADS score≥4 defined as being positive) in multi-parametric and bi-parametric evaluation, respectively (all P<0.001).
Conclusion: The bi-parametric VI-RADS scoring system can achieve a diagnostic efficacy comparable to that of the multi-parametric scoring system, offering an alternative to patients who are unable to undergo contrast-enhanced MRI due to allergic reaction to contrasts.

Liver cancer is one of the leading causes of cancer-related deaths worldwide. However, all liver cancer treatment options currently available fail to achieve a complete cure. Recently, research on pyroptosis has attracted significant attention from researchers in the field of cancer therapy. Pyroptosis is an inflammatory cell death closely related to oxidative stress caused by reactive oxygen species (ROS). The induction of pyroptosis can lead to the inhibition of tumor proliferation and the improvement of tumor immune responsiveness and is considered a novel therapeutic mechanism that can be utilized to develop new cancer therapies. Sonodynamic therapy (SDT), which involves a synergistic application of sonosensitizers and low-intensity focused ultrasound to generate cytotoxic ROS, demonstrates certain advantages and potentials in the treatment of liver cancer. However, liver cancer treatment utilizing SDT is still in the stage of preclinical research, and the specific conditions of ultrasound treatment, the biological effects, and the mechanisms of action are not fully understood. In this review, we discussed the potential of utilizing pyroptosis in liver cancer treatment, the mechanism of cancer therapy with ROS generated by SDT, and the latest findings concerning SDT from clinical and basic research. We discussed the utilization of SDT to force the accumulation of ROS in tumors to exceed the cytotoxicity threshold. Thus, SDT promotes pyroptosis and enhances the immune response to cancer. Furthermore, we discussed the prospects for applying the mechanism of SDT-induced pyroptosis in cancer therapy, thereby providing a better theoretical and experimental foundation for the clinical translation of SDT for liver cancer treatment.

No significant difference was observed between the two groups. Kaplan-Meier survival analysis showed that the median survival time (defined as the duration of patent access) was 670.00 (468.99, 871.01) days in the catheter group and 450.00 (339.24, 560.76) days in the AV access group, with the catheter group outperforming the AV access group.

目的评估上腔静脉闭塞(SVCO)血液透析患者应用经皮右心房穿刺和隧道袖带导管插入以及建立外周动静脉(AV)通路的情况,并为血管资源有限的患者重建血管通路提供循证支持:方法:纳入 SVCO 患者。方法:入选 SVCO 患者,然后根据患者的个人偏好为其实施右颈部经皮穿刺导管插入术或外周动静脉通路构建术。患者被相应地分为导管组和房室通路组。在双 C 臂数字减影血管造影术的引导下,在右臂静脉或上腔静脉残端进行穿刺。然后通过导丝插入门静脉分流器 RUPS100,用导丝的硬端穿刺右心房,使闭塞的上腔静脉急剧再通。随后,对阻塞性上腔静脉病变进行球囊扩张,并植入隧道式袖带导管。在 AV 入路组中,通过静脉造影术评估侧支静脉和超声波评估外周血管后,根据患者的血管条件和个人喜好建立自体 AV 管瘘或移植。记录人口统计学信息和临床结果,如主要通路和主要辅助通路的通畅情况,并监测并发症的发生率。将通畅时间定义为存活时间,进行卡普兰-米尔存活率分析,比较两组患者的通畅率:共有 45 例 SVCO 患者接受了血管通路重建手术。其中,导管组 21 例,动静脉通路组 24 例。所有患者都成功建立了血管通路并接受了血液透析,手术过程中未出现相关并发症或死亡。在平均(471.22±125.94)天的随访期内,导管组在6个月和12个月时的主要通畅率分别为95.2%和85.7%,主要辅助通畅率分别为100%和95.2%。在 6 个月和 12 个月时,动静脉通路组的主要通畅率分别为 79.2% 和 62.5%,主要辅助通畅率分别为 95.8% 和 87.5%。两组之间无明显差异。Kaplan-Meier 生存分析显示,导管组的中位生存时间(定义为通畅时间)为 670.00 (468.99, 871.01) 天,而 AV 通路组为 450.00 (339.24, 560.76) 天,导管组优于 AV 通路组。导管组的一次通畅率优于房室入路组(P=0.049)。另一方面,两组的主要辅助通畅率无明显差异:结论:通过经皮导管插入右心房上腔静脉残端或建立外周房室通路,可为 SVCO 患者建立长期血管通路。先建立房室通路,再进行导管插入术的综合方案有望改善长期血管通路的总持续时间,延长透析患者的总生存期,这为中心静脉资源枯竭患者重建透析通路提供了新思路。

Objective: To investigate the impact of the precise dissection and reconstruction of the prostate apex and bladder neck urethra during radical prostatectomy on the improvement in postoperative urinary control in patients with prostate cancer.
Methods: A retrospective study was conducted. A total of 131 prostate cancer patients who underwent robot-assisted radical prostatectomy at our institution between January 1, 2023 and December 31, 2023 were enrolled. The subjects were divided into two groups, with 64 in the experimental group and 67 in the control group. Patients in the experimental group underwent radical prostatectomy in a modified approach, while those in the control group underwent conventional radical prostatectomy. Propensity score matching was employed to match the two groups at a 1-to-1 ratio based on age, body mass index (BMI), preoperative prostate specific antigen (PSA), prostate volume, Prostate Imaging Reporting and Data System (PI-RADS) scores, biopsy Gleason score, and preoperative urinary control status. After matching, we compared the preoperative baseline data, surgical margin positivity rates, and urinary control status at 3 months post operation between the two groups. Urinary control was assessed before and after surgery using the International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form (ICIQ-UI SF) scale.
Results: A total of 56 pairs of patients were successfully matched between the experimental group and the control group through 1-to-1 propensity score matching. At 3 months after surgery, the median score for ICIQ-SF scale of the experimental group was 7.0 points, while that of the control group was 9.5 points, with the difference being statistical significant (P<0.05). There was no significant difference in the positive rate of incision margins between the experimental group and the control group. Multiple linear regression analysis showed that both the prostate volume and the Gleason score in the experimental group were positively correlated with the ICIQ-UI SF scores 3 months after surgery (P<0.05), while the age of patients in the control group was positively correlated with ICIQ-UI SF score 3 months after surgery (P<0.05).
Conclusion: Precise dissection and reconstruction of the prostate apex and bladder neck urethra during radical prostatectomy significantly improve the postoperative urinary control of patients at 3 months after surgery.

Objective: To investigate the effect of miR-2110 on the biological behaviors, such as cell proliferation, apoptosis, and metastasis, of lung adenocarcinoma (LUAD) cells by means of cell and animal experiments.
Methods: Bioinformatics websites, including ENCORI, TargetScan, miRTarBase, and Tarbase, were used to analyze the changes in the expression of miR-2110 in LUAD samples and to predict miR-2110 target. LUAD tissue samples and cells were collected and the changes in the expression of miR-2110 were verified through PCR technology. CCK-8 assay, clonogenic assay, Transwell assay, and flow cytometry were conducted to analyze alterations in the functions of LUAD cells. In addition, 10 BALB/c female nude mice aged 6 to 8 weeks were randomly divided into 2 groups, and the effect of miR-2110 on LUAD was investigated by in vivo experiments.
Results: miR-2110 was significantly decreased in LUAD tissues and cells compared with the normal lung tissues. miR-2110 overexpression inhibited the proliferation and metastasis of LUAD cells and promoted the apoptosis of tumor cells (P<0.05). Bioinformatics prediction and dual luciferase reporter gene assay results confirmed that miR-2110 could target and bind to CDT1. In addition, overexpression of CDT1 gene reversed the proliferation, metastasis, and apoptosis of miR-2110 compared with the miR-2110 overexpression group (P<0.05). Nude mice in vivo experiments showed that miR-2110 overexpression significantly decreased the expression of Ki67, a tumor proliferation index, and vimentin and MMP9, two metastasis indices, compared with the control group.
Conclusion: miR-2110 can inhibit proliferation and metastasis of LUAD by targeting CDT1, providing a new rationale for the treatment of LUAD.

With the increase in age, the oral function of older adults shows an age-related decline, which limits the types, quantity, and quality of their diet. Limited dietary intake can lead to a lack of basic nutrients needed for maintaining oral health, induce a series of oral diseases, and further aggravate the deterioration of oral functions. Oral frailty is the accumulation of mild oral function decline and is an emerging concept in the field of oral health. Currently, research on oral frailty and dietary intake mostly focuses on the impact of single-dimensional oral function decline on the dietary intake, dietary structure, and dietary satisfaction of older adults, as well as the impact of different dietary structures on the status of oral health among older adults. There is still a lack of large-sample, high-quality research on the relationship between comprehensive oral function decline and dietary intake. In addition, existing oral frailty intervention measures often place a narrow emphasis on the exercise and recovery of oral function without considering the impact of dietary intake and nutritional status on the development of oral frailty. Relevant research on taking dietary intake as an entry point or using it as a comprehensive intervention method also needs to be further explored by researchers. In the future, specialized assessment and screening of dietary status may be introduced in the routine health management practices for older adults. Furthermore, targeted intervention programs could also be proposed based on the characteristics of the oral status and the dietary intake habits of older adults, so as to prevent the functional decline related to dietary intake and nutritional supplementation. Herein, we reviewed the correlation between dietary intake and oral frailty to provide new ideas and directions for formulating comprehensive management strategies for oral frailty.

<p><strong>Objective: </strong>To investigate the clinicopathological features, immunophenotypes, molecular genetic alterations, and prognosis of succinate dehydrogenase-deficient renal cell carcinoma (SDH-RCC).</p><p><strong>Methods: </strong>A total of 11 cases of SDH-RCC diagnosed at West China Hospital, Sichuan University between 2016 and 2023 were selected for clinicopathological, immunohistochemical, and DNA sequencing analyses.</p><p><strong>Results: </strong>Among the 11 cases of SDH-RCC, there were 5 male patients and 6 female patients. The patients' ages ranged from 12 to 71 years, with an average age of 39.7 years. Among them, 5 patients had tumors located in the right kidney, 5 had tumors located in the left kidney, and 1 patient had bilateral tumors. Microscopic observation showed that the tumor cells of the SDH-RCC patients displayed a wide spectrum of structures, forming sheet-like, nested, and glandular structures. In addition, tumor cells in papillary structures were observed in some cases. The tumor cells had abundant cytoplasm, was eosinophilic, and contained flocculent materials. Intracytoplasmic vacuolations were observed in some of the cells. Among all the patients, 7 (7/11, 63.6%) showed typical low-grade features (grade 1-2 according to the International Society of Urological Pathology [ISUP]/WHO 2016 classification), and 4 (4/11, 36.4%) showed high-grade features (grade 3 according to the ISUP/WHO 2016 classification). The average ages of patients with low-grade and high-grade features were 32.1 years and 58.0 years, respectively. Immunohistochemical staining of all 11 cases demonstrated negative results for SDHB and cytokeratin 7 (CK7), and positive staining results for paired box 8 (PAX-8), fumarate hydratase (FH), and epithelial membrane antigen (EMA). Their Ki-67 index was 1%-30%. In one case, the loss of SDHB expression was also accompanied by a loss of SDHA expression. Sanger sequencing was performed to examine all the exons of <i>SDHB</i> in 7 cases.

Infertility is a global health issue, and more and more people are hoping to have babies by means of assisted reproductive technology. However, there are still many challenges in fertilization and pregnancy outcomes. Sperm quality is a key factor affecting the success rate of assisted reproduction. Therefore, sperm quality screening is crucial for achieving breakthroughs in assisted reproduction technology. At present, with its capabilities in the field of image recognition, artificial intelligence (AI) is providing new ideas and methods for sperm screening. Various attempts have been made with AI-based models to evaluate indicators such as sperm morphology, DNA quality, and motility level, and some results have been achieved. Herein, we reviewed the application of AI in sperm quality analysis and selection, providing support for the future development of AI and the improvement in the fertilization rate and outcomes of assisted reproductive technology.

Objective: To formulate a nutrition management protocol and processes for nasopharyngeal carcinoma patients undergoing chemoradiotherapy.
Methods: A nutrition management protocol and the process for nasopharyngeal carcinoma patients undergoing chemoradiotherapy were formulated on the basis of literature review and the Delphi expert consensus method.
Results: Literature analysis and two rounds of Delphi expert consultations via correspondence were conducted. The final protocol subsequently derived included 7 first-level items and 36 second-level items. The first-level items included the establishment of a nutrition management team, nutritional risk screening and nutritional status assessment, health education, the timing and method of nutritional treatment, energy and nutrient supply, nutritional monitoring, and follow-up after discharge. After summarizing the best evidence for the nutritional management protocol and classifying the evidence by different grades, the construction process of the nutrition management team and the nutrition management processes for the pre-cancer treatment period, the tumor treatment period, and the post-discharge follow-up period were formulated.
Conclusion: The nutritional management protocol and the relevant processes for nasopharyngeal carcinoma patients undergoing chemoradiotherapy formulated in this study demonstrate a certain level of scientific validity and reliability and can be further tested and applied in clinical practice.
