We report a case involving an 85-year-old man who underwent laparoscopic radical prostatectomy for prostate cancer in 2011. During follow-up, he required long-term use of a penile clamp to manage urination due to permanent severe stress incontinence. In February 2023, he presented with a painless cystic mass in the scrotum. Upon pressing the mass with hand, fluid drained from the external urethral orifice, causing the mass to shrink in size, although it returned to its original size a few hours later. Urography and cystoscopy showed a globular urethral diverticulum located anteriorly. The patient underwent surgical excision of the diverticulum along with urethroplasty. Postoperatively, the urinary stress incontinence persisted, but he declined any further surgical intervention. An artificial urinary sphincter is currently the first-line treatment for male urinary incontinence. However, devices such as penile clamps can serve as an alternative when considering surgical suitability or cost. It is important to note that these devices can lead to serious complications such as urethral erosion, stricture, or diverticulum. Therefore, caution is advised when using such devices, and they should be removed periodically at short intervals.

OBJECTIVE: To detect and analyze the expression and clinical significance of long non-coding RNA tyrosine kinase non-catalytic region adaptor protein 1-antisense RNA1 (NCK1-AS1) in patients with acute myeloid leukemia (AML). METHODS: 89 AML patients and 23 healthy controls were included from the People's Hospital Affiliated to Jiangsu University. Real-time quantitative polymerase chain reaction (RT-qPCR) was used to detect the expression levels of NCK1-AS1 and NCK1 in bone marrow samples. The relationship between the expression of NCK1-AS1 and the clinical characteristics of patients were analyzed, as well as the correlation between NCK1-AS1 and NCK1. RESULTS: The expression level of NCK1-AS1 in all AML, non-M3 AML and cytogenetically normal AML (CN-AML) patients was significantly higher than that in the control group (P < 0.01, P < 0.05, P < 0.01, respectively). In non-M3 AML, patients with high NCK1-AS1 expression had a significantly lower hemoglobin level than those with low NCK1-AS1 expression (P =0.036), furthermore, NCK1-AS1 ^high patients had shorter overall survival than NCK1-AS1^low patients (P =0.0378). Multivariate analysis showed that NCK1-AS1 expression was an independent adverse factor in patients with non-M3 AML ( HR =2.392, 95% CI :1.089-5.255, P =0.030). In addition, NCK1 expression was also significantly upregulated in all AML, non-M3 AML and CN-AML patients compared with controls (P < 0.01, P < 0.01, P < 0.001, respectively). There was a certain correlation between NCK1-AS1 and NCK1 expression (r =0.37, P =0.0058). CONCLUSION High expression of NCK1-AS1 in AML indicates poor prognosis of AML patients.

Photodynamic immunotherapy is a promising strategy for cancer treatment. However, the dysfunctional tumor vasculature results in tumor hypoxia and the low efficiency of drug delivery, which in turn restricts the anticancer effect of photodynamic immunotherapy. In this study, we designed photosensitive lipid nanoparticles. The synthesized PFBT@Rox Lip nanoparticles could produce type I/II reactive oxygen species (ROS) by electron or energy transfer through PFBT under light irradiation. Moreover, this nanosystem could alleviate tumor hypoxia and promote vascular normalization through Roxadustat. Upon irradiation with white light, the ROS produced by PFBT@Rox Lip nanoparticles in situ dysregulated calcium homeostasis and triggered endoplasmic reticulum stress, which further promoted the release of damage-associated molecular patterns, enhanced antigen presentation, and stimulated an effective adaptive immune response, ultimately priming the tumor microenvironment (TME) together with the hypoxia alleviation and vessel normalization by Roxadustat. Indeed, in vivo results indicated that PFBT@Rox Lip nanoparticles promoted M1 polarization of tumor-associated macrophages, recruited more natural killer cells, and augmented infiltration of T cells, thereby leading to efficient photodynamic immunotherapy and potentiating the anti-primary and metastatic tumor efficacy of PD-1 antibody. Collectively, photodynamic immunotherapy with PFBT@Rox Lip nanoparticles efficiently program TME through the induction of immunogenicity and oxygenation, and effectively suppress tumor growth through immunogenic cell death and enhanced anti-tumor immunity.

Objective To explore the changes in trace elements and amino acid profiles in serum of patients with hepatocellular carcinoma(HCC) providing a reference for clinical diagnosis and treatment.Methods A total of 104 patients with HCC who underwent surgical treatment in the Department of Hepatobiliary Surgery of our hospital from January 2024 to April 2024 were selected as the study group, and 139 patients with benign biliary diseases during the same period were selected as the control group. Atomic absorption spectrometry was used to detect the levels of six trace elements (copper, zinc, calcium, magnesium, iron, and lead) in the serum of both groups, and liquid chromatography-tandem mass spectrometry was used to measure the concentrations of 21 amino acids.Results Compared with the control group, the serum copper level in the HCC group was significantly increased (P<0.05), while the levels of zinc and iron were significantly decreased (P<0.05). Amino acid profile analysis revealed that, compared with the control group, the concentrations of tyrosine, methionine, and phenylalanine in the HCC group were increased (P<0.05), while the concentrations of valine, leucine, isoleucine, glutamine, and arginine were decreased (P<0.05). Further analysis of the correlation between trace elements and amino acids with statistical differences between the groups showed that copper was negatively correlated with valine and leucine (P<0.05), while zinc and iron were positively correlated with valine, leucine, and isoleucine (P<0.01).Conclusions Imbalances in trace elements and amino acid metabolism changes are common in patients with HCC, and there may be an intrinsic connection between the two.

Objective To investigate the potential mechanisms of anti-dizziness drugs in treating motion sickness.Methods Literature mining was utilized to obtain commonly used drugs for the treatment of dizziness.Corresponding targets for motion sickness were identified using databases such as GeneCards and literature,while the Herb database was used to obtain targets corresponding to drugs.Venn diagrams were employed to find the intersection of drug treatment targets,and the DAVID database was used for KEGG and GO analysis to determine the pathways corresponding to these targets.Sankey diagram tools were used to obtain the number of significant pathways corresponding to each target,thereby identifying core targets.The TCMSP database and literature were used to acquire the effective chemical components corresponding to each drug,and core components were determined based on the number of corresponding drugs.The intersection with core targets was taken to identify corresponding targets.The HPA database,along with single-cell transcriptomics and spatial transcriptomics,was used to determine the distribution of corresponding targets in brain neurons.Finally,AutoDock was used to determine the docking status between core effective components and core targets.Results A literature database was used to obtain 13 high-frequency drugs for treating dizziness,with 379 corresponding targets after deduplication.Databases and literature provided 1198 high-credibility targets corresponding to motion sickness,with 89 intersection targets between drugs and diseases.GO enrichment analysis yielded 1237 significant entries,including positive regulation of miRNA transcription,and KEGG enrichment analysis identified 51 neural function-related signaling pathways,such as the neuroactive ligand-receptor interaction pathway and the glutamatergic synapse pathway.Sankey diagrams identified 18 core genes,including MAPK3,AKT1,MAPK1,PRKCA,and INSR;drug component analysis determined beta-sitosterol as the core component,which can form good molecular docking with MAPK14,Bcl-2,and PRKCA.Conclusion Anti-dizziness drugs possess the potential to treat motion sickness and may exert neuroprotective effects through neural function-related pathways such as the neuroactive ligand-receptor interaction pathway and the glutamatergic synapse pathway.beta-sitosterol,as a core natural compound,can interact with proteins related to neural function and warrants further research and exploration.

Objective:To compare the efficacy of body posture combined with pharmacotherapy and pharmacotherapy alone in the treatment of chronic subdural hematoma(CSDH).Methods:Firstly, retrospective case series study was conducted. Thirty cases of CSDH that had received body posture combined with pharmacotherapy at Department of Neurosurgery, Huashan Hospital Affiliated to Fudan University from December 2016 to October 2020 were studied retrospectively. Twenty-seven patients were male, and 3 patients were female. The age of patients ( M(IQR)) was 66(16) years (range:28 to 84). Nineteen patients had unilateral hematoma, and 11 patients had bilateral hematoma. All patients received pharmacotherapy and body posture therapy that was to raise their lower limbs 20 to 30 cm with leg lift pad and get abdominal compressed with customized abdominal belt in supine position. Patients were required to maintain the body posture as much as possible, with the maximum to 16 to 18 hours per day. Patients with unilateral hematoma should tilt the head to the affected side and avoid tilting it to the opposite side. For patients with bilateral hematoma, there was no need for head lateralization. Patient were treated with oral dexamethasone and atorvastatin simultaneously. The preliminary efficacy of body posture combined with pharmacotherapy was determined by hematoma improvement rate which was analyzed by Clopper-Pearson method. Then, the multi-center, prospective, randomized controlled trial had carried out in 9 medical centers from August 2020 to November 2021. The stratified block randomization method was adopted. Patients were randomized in a ratio of 1∶1 to either receive pharmacotherapy alone(the control group) or body posture combined with pharmacotherapy(the experiment group) for 3 months and followed up for 6 months. Effective treatment was defined as complete absorption of hematoma, or the hematoma volume decreased by more than 10 ml and Markwalder grading scale score had improved by more than 1 point compared to the baseline. The efficacy rate and surgery conversion rate at 3 months and recurrence at 6 months were observed. Comparison between groups was performed with paired sample t test, Mann-Whitney U test, χ2 test, corrected χ2 test, or Fisher exact probability method. Logistic regression was used to compare the effective rate and operation rate between the two groups. Results:In the respective study, 30 patients completed follow-up 13 to 353 days after treatment. At the last follow-up, the incidence of almost complete absorption or significantly absorption of hematoma (hematoma volume was significantly reduced accompanied by symptom improvement) was 93.3%. The 95% CI for the incidence that analyzed by the Clopper-Pearson method was 77.9% to 99.2%. One hundred and six patients were enrolled in the multicenter study. Fifty-five patients underwent body posture combined with pharmacotherapy. The age was 74(17) years (range:26 to 92). Thirty-nine patients were males and 16 were females. Fifty-one patients underwent pharmacotherapy alone. The age was 69(12) years (range:48 to 84). Thirty-seven patients were males and 14 were females. The length of body posture recorded in diary card was (15.7±2.3) hours(range:7.6 to 19.3 hours). The efficacy rate in the body posture combined with pharmacotherapy group and pharmacotherapy alone group were 83.6% (46/55) and 56.9% (29/51), respectively at 3 months. The result of the logistic regression analysis showed that the efficacy of body posture combined with pharmacotherapy group was better than that of pharmacotherapy alone group ( OR=3.88,95% CI:1.57 to 9.58, P=0.003). Surgery rate in the body posture combined with pharmacotherapy group and pharmacotherapy alone group were 5.5% (3/55) and 21.6% (11/51) respectively. The result of Logistic regression showed that the pharmacotherapy alone group was more likely to be converted to surgery ( OR=0.21,95% CI:0.05 to 0.80, P=0.023). At the 6 months, no recurrence of cases was found in the body posture combined with pharmacotherapy group. However, the recurrence rate of pharmacotherapy alone group was 6.3% (3/48), there was no significant difference between the two groups ( P>0.05). Conclusion:The effect of body posture combined with pharmacotherapy for chronic subdural hematoma is better than that of pharmacotherapy alone.

Epilepsy is one of the most common chronic brain diseases,and taking anti-seizure medications(ASMs)is the main treatment method.When patients with epilepsy achieve long-term remission,gradually reducing ASMs has become a common concern for both patients and doctors.However,there is significant heterogeneity in current research on withdrawal of epilepsy medication.This article provides a literature review on whether patients with epilepsy who have been taking ASMs for a long time without seizures can be withdrawn,how long it takes to withdraw without seizures,how to withdraw medication,recurrence and prognosis after withdrawal,and factors affecting recurrence and prognosis.

Objective:To explore the establishment, implementation, and application effect of the annual progressive assessment mode for standardized training of resident physicians in a medical laboratory base.Methods:Since 2020, the base has improved the annual progressive assessment system through assessment system establishment, question bank construction, routine assessment, rotation examination, and annual examination. This new assessment mode was adopted for the residency trainees enrolled in the base after 2020. The control group consisted of seven residency trainees enrolled before 2020, while the experimental group comprised 13 trainees enrolled in 2020 and later. The two groups were compared based on the rotation and annual examination scores of second- and third-year trainees, as well as their academic achievements. Additionally, teaching outcomes of the base before and after 2020 were analyzed. The t test, rank-sum test, and Fisher's exact test were performed using SPSS 27.00. Results:There were no significant differences in age, sex, and education level between the two groups. The experimental group showed significantly higher scores than the control group in theory assessment ( P<0.001 for second-year trainees and P=0.008 for third-year trainees) and skill assessment ( P<0.001 for second-year trainees and P=0.038 for third-year trainees) in rotation examination, as well as in theory assessment (both P<0.001) and skill assessment (both P<0.001) in annual examination. The improvement was particularly pronounced among second-year trainees. The trainees of the experimental group submitted 17 case reports in three years, and won awards at national conferences, provincial conferences, and institutional case speech competitions. In a national academic conference, the trainees won the second prize of "Excellent Case". Since 2020, we have been granted with our first teaching reform project and published our first teaching article. To date, we have obtained five teaching reform projects, published six teaching articles, and won multiple awards in provincial and institutional teaching competitions. Conclusions:The establishment of the annual progressive assessment mode is critical for training high-quality laboratory physicians, and puts forward higher requirements for residency training teachers.
