RESUMEN
Kidney renal clear cell carcinoma (KIRC) is a highly immune-infiltrated kidney cancer with the highest mortality rate and the greatest potential for invasion and metastasis. Solute carrier family 11 member1 (SLC11A1) is a phagosomal membrane protein located in monocytes and plays a role in innate immunity, autoimmune diseases, and infection, but its expression and biological role in KIRC is still unknown. In this study, we sought to investigate the potential value of SLC11A1 according to tumor growth and immune response in KIRC. TIMER and UALCAN database was used to analyze the expression feature and prognostic significance of SLC11A1 and its correlation with immune-related biomarkers in KIRC. Proliferation, migration, and invasion were measured using colony formation, EdU, and transwell assays. Role of SLC11A1 on KIRC tumor growth was examined by the xenograft tumor model in vivo. Effects of KIRC cells on macrophage polarization and the proliferation and apoptosis of CD8+ T cells were analyzed using flow cytometry assays. Herein, SLC11A1 was highly expressed in KIRC tissues and cell lines. SLC11A1 downregulation repressed KIRC cell proliferation, migration, invasion, macrophage, and lymphocyte immunity in vitro, as well as hindered tumor growth in vivo. SLC11A1 is significantly correlated with immune cell infiltration and immune-related biomarkers. In KIRC patients, SLC11A1 is highly expressed and positively correlated with the immune-related factors CCL2 and PD-L1. SLC11A1 induced CCL2 and PD-L1 expression, thereby activating the JAK/STAT3 pathway. SLC11A1 deficiency constrained KIRC cell malignant phenotypes and immune response via regulating CCL2 and PD-L1-mediated JAK/STAT3 pathway, providing a promising therapeutic target for KIRC treatment.

BACKGROUND: Insulin-like growth factor 2 mRNA-binding protein 2 (IGF2BP2) has been confirmed to play oncogenic role in many cancers. However, the role and mechanism of IGF2BP2 in bladder cancer (BCa) still deserves to be further revealed. METHODS: The mRNA and protein levels of IGF2BP2 and neuronilin-1 (NRP1) were detected by real-time quantitative PCR (RT-qPCR) and western blot. Cell proliferation, apoptosis, migration and invasion were determined using colony formation assay, EdU assay, CCK8 assay, flow cytometry and transwell assay. Xenograft tumor model was conducted to evaluate the role of IGF2BP2 in vivo. THP-1-M0 macrophages were co-cultured with the condition medium (CM) of BCa cells to induce polarization. M2 macrophage polarization was assessed by detecting the mRNA levels of M2 macrophage markers using RT-qPCR and measuring the proportion of M2 macrophage markers using flow cytometry. Moreover, MeRIP and RIP assay were performed to assess m6A level and the interaction between IGF2BP2 and NRP1. RESULTS: IGF2BP2 and NRP1 were upregulated in BCa tissues and cells. IGF2BP2 knockdown suppressed BCa cell growth and metastasis, as well as inhibited BCa tumor growth. After THP-1-M0 macrophages were co-cultured with the CM of BCa cells, the levels of M2 macrophage markers were markedly enhanced, while this effect was abolished by IGF2BP2 knockdown. IGF2BP2 level was positively correlated with NRP1 level, and it could increase NRP1 mRNA stability. NRP1 overexpression reversed the suppressive effect of IGF2BP2 knockdown on M2 macrophage polarization and BCa cell progression. CONCLUSION: m6A-reader IGF2BP2 enhanced M2 macrophage polarization and BCa cell progression by promoting NRP1 mRNA stability.

OBJECTIVE: To explore the effect of the "internet + health education system" in nursing care after stapler circumcision. METHODS: A total of 260 patients underwent stapler circumcision in the Outpatient Department of our hospital from January 2022 to July 2022, of whom 130 received routine nursing after operation (the control group), and the other 130 internet + medical nursing service based on the internet + health education system (the experimental group). We followed up the patients on the 1st, 3rd, 7th and 30th day after surgery, recorded their Visual Analogue Scale (VAS) scores within 24 hours postoperatively, their satisfaction scores with surgery and nursing, the incidence of complications and falloff of the stapler nails, and compared them between the two groups. RESULTS: The postoperative VAS scores of the patients and the incidences of postoperative edema, bleeding, infection and other complications were significantly lower (P < 0.05), the falloff of the stapler nails markedly sooner, and the patients' satisfaction scores with surgery and nursing service remarkably higher (P < 0.05) in the experimental than in the control group (P < 0.05). CONCLUSION: The application of the internet + health education system in nursing care after stapler circumcision can impart relevant knowledge to the patients, enhance their self-care ability, effectively reduce postoperative complications, and improve the patients' satisfaction with surgery and nursing service.

OBJECTIVE: To explore the clinical manifestations, diagnosis, pathological features and treatment of small-cell carcinoma of the prostate (SCCP). METHODS: We conducted a retrospective analysis of the clinical and pathological data of 2 cases of confirmed SCCP treated from November 2017 to March 2018, and reviewed relevant literature. RESULTS: Both the patients had the symptoms of frequent, urgent and difficult urination, with an elevated level of PSA and gradesâ ¡ï¼â ¢ enlargement of the prostate at palpation. One underwent prostate puncture biopsy and the other received transurethral 1470 laser vaporization resection of the tumor. Postoperative pathology indicated prostate adenocarcinoma accompanied by SCCP in both of the cases. One of them was treated by etoposide-platinum (EP) chemotherapy and died of systemic multiple organ failure 20 months after diagnosis, while the other underwent endocrine therapy and has lived with tumor up to the present day. CONCLUSION: The incidence rate of SCCP is low, its malignancy is high, and its prognosis is poor. The average survival of the patient is about 7 to 10 months after diagnosis. Currently there is no effective management of the dissease, except by relying on the experience of the treatment of small-cell lung cancer, with chemotherapy as the main option.

OBJECTIVE: To evaluate the efficiency of the four domestic language models, ERNIE Bot, ChatGLM2, Spark Desk and Qwen-14B-Chat, all with a massive user base and significant social attention, in response to consultations about PCa-related perioperative nursing and health education. METHODS: We designed a questionnaire that includes 15 questions commonly concerned by patients undergoing radical prostatectomy and 2 common nursing cases, and inputted the questions into each of the four language models for simulation consultation. Three nursing experts assessed the model responses based on a pre-designed Likert 5-point scale in terms of accuracy, comprehensiveness, understandability, humanistic care, and case analysis. We evaluated and compared the performance of the four models using visualization tools and statistical analyses. RESULTS: All the models generated high-quality texts with no misleading information and exhibited satisfactory performance. Qwen-14B-Chat scored the highest in all aspects and showed relatively stable outputs in multiple tests compared with ChatGLM2. Spark Desk performed well in terms of understandability but lacked comprehensiveness and humanistic care. Both Qwen-14B-Chat and ChatGLM2 demonstrated excellent performance in case analysis. The overall performance of ERNIE Bot was slightly inferior. All things considered, Qwen-14B-Chat was superior to the other three models in consultations about PCa-related perioperative nursing and health education. CONCLUSION: In PCa-related perioperative nursing, large language models represented by Qwen-14B-Chat are expected to become powerful auxiliary tools to provide patients with more medical expertise and information support, so as to improve the patient compliance and the quality of clinical treatment and nursing.

OBJECTIVE: To explore the safety and effectiveness of the "scarless" circumcision technique (a modified sleeve-style circumcision method) that preserves the original appearance, providing a more suitable surgical option for patients with redundant prepuce. METHODS: Clinical data of patients who underwent "scarless" circumcision at the Eastern Theater Command General Hospital from April 2022 to March 2023 were collected, with patients who underwent conventional circumcision (single-use stapler method) during the same period serving as the control group. The two groups were compared in terms of operation time, postoperative recovery time, incidence of postoperative complications, and patient satisfaction rates after surgery. RESULTS: The operation time for the study group was significantly longer than that of the control group; there was no significant difference in pain scores on the day of surgery between the two groups, but the pain scores on postoperative days 1, 3, and 7 were lower in the study group than in the control group; the postoperative recovery time was significantly shorter in the study group than in the control group; regarding postoperative complications: the control group had higher rates of edema, incision infection, and wound dehiscence than the study group. A satisfaction survey conducted 30 days postoperatively showed higher satisfaction in the study group than in the control group. CONCLUSION: The "scarless" circumcision technique that preserves the original appearance is safe and effective for patients with simple redundant prepuce and is a new surgical method with value for widespread adoption.

BACKGROUND: Studies over the past decade have shown that competitive endogenous RNA (ceRNA) plays an essential role in the tumorigenesis and progression of clear cell renal cell carcinoma (ccRCC). Meanwhile, immune checkpoint blocker is gradually moving towards the first-line treatment of ccRCC. Hence, it's urgent to develop a new prediction model for the efficiency of immunotherapy. At present, there is no study to reveal the effect of ceRNA network on the efficiency of immunotherapy for ccRCC. METHODS: To systematically analyze the effect of ceRNA hub genes in ccRCCon immune response, we constructed prognosis models based on ceRNAs and immune cells, respectively. We constructed ceRNA network using hypergeometric distribution test and correlation analysis with R script based on The Cancer Genome Atlas (TCGA) database. We then applied the Cibersort algorithm to simulate the infiltration overview of immune cells in kidney renal clear carcinoma (KIRC) samples. Prognosis-related immune cells were screened and a predictive model of these cells was constructed. Prognosis-related immune cells and ceRNA hub genes were performed with co-expression analysis. Finally, qRT-PCR and immunofluorescence assays were performed to validate the results. RESULTS: The construction of ceRNA related prognosis model contained 8 hub genes, including RELT, MYO9B, KCNN4, SIX1, OTOGL, MALAT1, hsa-miR-130b-3p, and hsa-miR-21-5p. The area under the receiver operating characteristic curve (AUC) was 0.77 at 5 years. For the construction of immune cells prognosis model, 3 immune cells (T cells regulatory, Macrophages, Mast cells resting) were adopted, and the AUC was 0.65 at 5 years. We then merged the two models by correlation analysis and co-expression analysis. Finally, we found that KCNN4 positively correlates with T cells regulatory (Tregs) and negatively correlates with mast cells resting significantly. Furthermore, higher expression of KCNN4 may lead to a higher potential for immune evasion and lower efficiency for immune checkpoint inhibitors (ICIs). CONCLUSIONS: Generally, this is the first study to assess the prognostic value of immune related ceRNA hub genes in ccRCC, and KCNN4 was finally demonstrated to be a key regulatory factor with strong correlation with Tregs and mast cells resting.
RESUMEN
BACKGROUND: Tumorigenic phenotype of M2 tumor-associated macrophages promote tumor progression in response to exosomes cues imposed by tumor cells. However, the effect and underlying mechanisms of clear cell renal cell carcinoma (ccRCC)-derived exosomes (ccRCC-exo) on instructing macrophages phenotype remains unclear. METHODS: Macrophages were cocultured with ccRCC-exo and then evaluate the polarization of macrophages and migration of ccRCC cells. The effect and mechanism of lncRNA AP000439.2 overexpressed or deleted exosomes on macrophages M2 polarization were examined. Xenograft tumor mice model was used for in vivo validation. RESULTS: The ccRCC-exo significantly activated macrophages to M2 phenotype presented by increased expression of transforming growth factor-beta (TGF-ß) and interleukin 10 (IL-10) at mRNA and protein levels, and these M2 macrophages in turn facilitating the migration of ccRCC cells. LncRNA AP000439.2 was highly enriched in the ccRCC-exo. Overexpression of exosomal AP000439.2 promoted M2 macrophage polarization whereas AP000439.2-deficient exosome had the opposite effects. Nuclear-localized AP000439.2 directly interacted with signal transducer and activator of transcription 3 (STAT3) proteins and phosphorylated STAT3 in macrophages. RNA-Seq results showed overexpression of AP000439.2 activated NF-κB signaling pathway. Silencing of STAT3 suppressed overexpression of AP000439.2-induced up-regulation of TGF-ß and IL-10 expression, and p65 phosphorylation. AP000439.2-deleted exosome inhibited tumor growth in vivo. CONCLUSION: Exosomes from ccRCC deliver AP000439.2 to promote M2 macrophage polarization via STAT3, thus enhancing ccRCC progression, indicating exosomal AP000439.2 might be a novel therapeutic target in ccRCC.

OBJECTIVE: To explore the clinical diagnosis and treatment of testicular cavernous hemangioma (TCH). METHODS: We retrospectively analyzed the clinical data on a case of TCH associated with testicular torsion treated in our hospital and reviewed the relevant literature. RESULTS: The patient underwent "right orchiectomy" after preoperative examinations. Intraoperative pathology indicated testicular parenchyma infarction, and postoperative pathology showed cavernous hemangioma with hemorrhage and infarction. No recurrence was observed during 3 years of postoperative follow-up. CONCLUSION: Testicular cavernous hemangioma is an extremely rare benign tumor of the testis, and rarely associated with testicular torsion. Preoperative and intraoperative pathology provides a basis for the selection of reasonable treatment.

OBJECTIVE: To discuss the clinical diagnosis and treatment of extragonadal germ cell tumor. METHODS: We analyzed the clinical data on a case of extragonadal germ cell tumor diagnosed and treated in the General Hospital of Eastern Theater Command and reviewed the relevant literature. RESULTS: The patient was initially diagnosed with retroperitoneal tumor and treated by resection of the tumor together with the left kidney due to the large volume of the tumor, which was complicated by pancreatic injury. Postoperative pathology showed it to be extragonadal germ cell malignancy. Postoperative examination revealed space-occupying lesion in the left testis, with serum alpha fetoprotein (AFP), human chorionicgonadotropin (hCG) and lactate dehydrogenase (LDH) negative, followed by stage-two resection of the left testis, which was pathologically shown with testicular seminoma. The patient received 7 courses of cisplatin, etoposide bleomycin (PEB) regimen and was followed up for 8 years, which found no recurrence or metastasis, and the patient fathered no child during the postoperative follow-up. CONCLUSION: For patients with a history of cryptorchidism and tumors located in the central axis, special attention should be paid to physical examination of the testes, testicular ultrasonography, and determination of AFP and other indicators to identify gonadal tumor metastasis. And if so, radiotherapy and chemotherapy can be considered first to reduce surgical complications and achieve accurate management.

The discovery of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and the outbreak of coronavirus disease 2019 (COVID-19) are causing public health emergencies. A handful pieces of literature have summarized its clinical and radiologic features, whereas therapies for COVID-19 are rather limited. To evaluate the efficacy of convalescent plasma therapy in COVID-19 patients, we did this timely descriptive study. Six laboratory-confirmed COVID-19 patients were enrolled and received the transfusion of ABO-compatible convalescent plasma. The efficacy of this intervention was determined by the alleviation of symptoms, changes in radiologic abnormalities and laboratory tests. No obvious adverse effect observed during the treatment. Transfusion of convalescent plasma led to a resolution of ground-glass opacities and consolidation in patients #1, #2, #3, #4, and #6. In patients #1 and #5 who presented with SARS-CoV-2 in throat swab, convalescent plasma therapy elicited an elimination of the virus. Serologic analysis indicated an immediate increase in anti-SARS-CoV-2 antibody titers in patients #2 and #3, but not in patient #1. This study indicates that convalescent plasma therapy is effective and specific for COVID-19. This intervention has a special significance for eliminating SARS-CoV-2 and is believed to be a promising state-of-the-art therapy during COVID-19 pandemic crisis.

Nobiletin, a flavonoid found chiefly in oranges and lemons, has exhibited potential anti-proliferative and pro-apoptotic activities in various types of cancers. However, the inhibitory effect and mechanisms of nobiletin on renal cancer cells are unclear. CCK8 and plate clone formation assay were used to determine the effect of nobiletin on the proliferation of renal cancer cells, while scratch healing test was used to assay its effect on migration ability. The effect of nobiletin on the invasion of renal cancer cells was determined using Trans well chamber assay. Flow cytometry was used to determine the effect of nobiletin on apoptosis of renal cancer cells, while Western blotting assay was used to determine its effect on the expressions of JAK2/STAT3 and PI3K/Akt pathway proteins, and apoptosis-related proteins. Nobiletin inhibited the proliferation of renal carcinoma cells in a time- and dose-dependent manner. It inhibited the migration and invasion of renal cancer cells, and promoted their apoptosis. Western blot results showed that nobiletin inhibited the phosphorylations of JAK2, STAT3, PI3K, and Akt, and promoted the expressions of apoptosis-related proteins. Nobiletin inhibits the proliferation, invasion and migration of renal cell carcinoma by inhibiting JAK2/STAT3 and PI3K/Akt pathways, and promotes their apoptosis. These findings provide a new experimental basis for the application of nobiletin in the treatment of renal cancer.

OBJECTIVE: To study the therapeutic effect of Lamiophlomis Rotata Capsule (LRC) in the treatment of type â ¢B prostatitis. METHODS: We randomly divided 225 patients with type â ¢B prostatitis into an experimental group (n =125) and a control group (n =120), the former treated orally with LRC at 3 capsules tid while the latter with tamsulosin hydrochloride sustained-release capsules at 0.2 mg qd, both for 4 weeks. We compared the therapeutic effects between the two groups of patients based on the National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI) obtained before, immediately after and at 4 weeks after medication. RESULTS: A total of 120 patients completed the treatment in the experimental group, which showed remarkable decreases as compared with the baseline in the pain score (5.30 ± 1.23 vs 14.68 ± 1.51, P<0.05), quality of life (QoL) score (6.46 ± 0.93 vs 8.52 ± 1.05, P<0.05) and total NIH-CPSI score (17.50 ± 2.77 vs 27.99 ± 2.98, P<0.05) after 4 weeks of treatment, but no significant change in the urination symptoms score (7.41 ± 1.16 vs 7.16 ± 1.04, P>0.05). The experimental group achieved even markedly lower scores than the controls in the pain symptom (5.30 ± 1.23 vs 13.67 ± 1.49, P<0.05), QoL (6.46 ± 0.93 vs 7.47 ± 0.88, P<0.05) and total NIH-CPSI (17.50 ± 2.77 vs 25.77 ± 2.01, P<0.05) but a higher urination symptoms score than the latter after medication (7.16 ± 1.04 vs 5.68 ± 1.34, P<0.05). At 4 weeks after drug withdrawal, the experimental group also showed significantly lower scores of the pain symptom (7.23 ± 1.03), QoL (6.58 ± 0.87) and total NIH-CPSI (22.18 ± 2.03) than the baseline (all P<0.05) and those in the control group (14.14 ± 0.98, 8.12 ± 0.72 and 26.89 ± 1.67) (all P<0.05). Apart from dizziness in 2 of the patients, who gave up medication halfway, no other obvious adverse reactions were observed during the experiment. CONCLUSIONS: Lamiophlomis Rotata Capsule deserves to be recommended for the treatment of type â ¢B prostatitis for its safety and effectiveness in reducing the pain and improving the life quality of the patients.

Neuropilin-1 (NRP-1) overexpression has been reported in a variety of human cancers. However, the role of NRP-1 in bladder cancer (BC) remains unclear. The aim of present study was to analyze NRP-1 protein expression in BC tissues and to assess its prognostic significance for BC. NRP-1 messenger ribonucleic acid (mRNA) and protein expression were determined by real-time quantitative reverse transcriptase-polymerase chain reaction (qRT-PCR) and immunohistochemistry in specimens of primary cancer and their adjacent noncancerous tissues in BC patients. Additionally, NRP-1 protein expression in 139 archived paraffin-embedded BC samples was analyzed by immunohistochemistry and correlated with clinicopathological characteristics and survival. Student's t test, Spearman's rank correlation, Kaplan-Meier plots, and Cox's proportional hazards regression model were used to analyze the data. By qRT-PCR and immunohistochemistry, the levels of NRP-1 mRNA and protein were significantly higher in BC, compared to that in adjacent noncancerous tissues (P<0.001). High expression of NRP-1 was significantly associated with histologic grade (P=0.016) and tumor stage (P=0.001). Multivariate analysis showed that high expression of NRP-1 was an independent prognostic factor for overall survival. Our study suggests that overexpression of NRP-1 may play an important role in the progression of BC, and NRP-1 expression may serve as a biomarker for poor prognosis for BC.
