Advances in systemic immune inflammatory indices in non-small cell lung cancer: A review.

Lung cancer is one of the most prevalent cancers globally, with non-small cell lung cancers constituting the majority. These cancers have a high incidence and mortality rate. In recent years, a growing body of research has demonstrated the intricate link between inflammation and cancer, highlighting that inflammation and cancer are inextricably linked and that inflammation plays a pivotal role in cancer development, progression, and prognosis of cancer. The Systemic Immunoinflammatory Index (SII), comprising neutrophil, lymphocyte, and platelet counts, is a more comprehensive indicator of the host's systemic inflammation and immune status than a single inflammatory index. It is widely used in clinical practice due to its cost-effectiveness, simplicity, noninvasiveness, and ease of acquisition. This paper reviews the impact of SII on the development, progression, and prognosis of non-small cell lung cancer.

Migrated Hem-o-Lok clips in the neobladder with giant stone formation: a case report.

INTRODUCTION: Neobladder urolithiasis is a rare but important delaying complication of orthotopic urinary diversion. We report a case of Hem-o-Lok (HOLC) migration into the neobladder with giant stone formation after orthotopic neobladder cystectomy. CASE REPORT: We report a case of a 57-year-old man with frequent urination and occasional discharge of stones 3 years after a laparoscopic orthotopic neobladder cystectomy. Computed tomography revealed a large round 3.5 cm calculus. An endoscopic neocystolitholapaxy was performed, and a Hem-o-Lok was found in the center of the stone. CONCLUSION: We described the case presentation, treatment and analysis of etiology of stone formation to avoid such complication.

A combined model based on CT radiomics and clinical variables to predict uric acid calculi which have a good accuracy.

The aim of this study was to develop a CT-based radiomics and clinical variable diagnostic model for the preoperative prediction of uric acid calculi. In this retrospective study, 370 patients with urolithiasis who underwent preoperative urinary CT scans were enrolled. The CT images of each patient were manually segmented, and radiomics features were extracted. Sixteen radiomics features were selected by one-way analysis of variance (ANOVA) and least absolute shrinkage and selection operator (LASSO). Logistic regression (LR), random forest (RF) and support vector machine (SVM) were used to model the selected features, and the model with the best performance was selected. Multivariate logistic regression was used to screen out significant clinical variables, and the radiomics features and clinical variables were combined to construct a nomogram model. The area under the receiver operating characteristic (ROC) curve (AUC), etc., were used to evaluate the diagnostic performance of the model. Among the three machine learning models, the LR model had the best performance and good robustness of the dataset. Therefore, the LR model was used to construct the nomogram. The AUCs of the nomogram model in the training set and validation set were 0.878 and 0.867, respectively, which were significantly higher than those of the radiomics model and the clinical feature model. The CT-based radiomics model based has good performance in distinguishing uric acid stones from nonuric acid stones, and the nomogram model has the best diagnostic performance among the three models. This model can provide an effective reference for clinical decision-making.

Application of a novel computer-assisted surgery system in percutaneous nephrolithotomy: A controlled study.

BACKGROUND: Most complex renal stones are managed primarily with percutaneous nephrolithotomy (PCNL). However, PCNL is still a great challenge for surgeons because of poor comprehension on complex adjacent structures. Novel techniques are required to assist in planning and navigation. AIM: To apply and evaluate the Hisense computer-assisted surgery (CAS) system in PCNL. METHODS: A total of 60 patients with complex renal stones were included. Thirty patients in the CAS group had three-dimensional (3D) virtual models constructed with the CAS system. The model assisted in planning and navigating in the CAS system. Thirty patients in the control group planned and navigated as standard PCNL, without the application of the CAS system. Success rate of one attempt, operation time, initial stone-free rate, decrease in hemoglobin, and complications were collected and analyzed. RESULTS: There were no statistically significant differences in the baseline characteristics or planning characteristics. The success rate of one puncturing attempt (90% vs 67%, P = 0.028) and the initial stone-free rate (87% vs 63%, P = 0.037) were significantly higher in the CAS group. However, there were no statistically significant differences in the operation time (89.20 ± 29.60 min vs 92.33 ± 33.08 min, P = 0.859) or in the decrease in hemoglobin (11.07 ± 8.32 g/L vs 9.03 ± 11.72 g/L, P = 0.300) between the CAS group and the control group. No statistically significant differences in the incidence of complications (Clavien-Dindo grade ≥ 2) were found. CONCLUSION: Compared with standard PCNL, CAS-assisted PCNL had advantages in terms of the puncturing success rate and stone-free rate. The Hisense CAS System was recommended to assist in preoperative planning and intraoperative navigation for an intuitive, precise and convenient PCNL.

The Effect of Exposure to Bisphenol A on Spermatozoon and the Expression of Tight Junction Protein Occludin in Male Mice.

Although bisphenol A (BPA) has been associated with impaired spermatogenesis, the mechanisms remain unclear. Tight junction occludin plays important roles in spermatogenesis. The objective of the present study was to explore the effects of BPA exposure in adolescent mice. Male mice were orally treated with low-dose (0.05 mg/kg/d), middle-dose (5.0 mg/kg/d), or high-dose (50 mg/kg/d) BPA in corn oil from postnatal day (PND) 35 to 65. Animals were killed on PND 65 and PND 125. On PND 65, the sperm count, sperm motility, and the expression of occludin showed a dose-related decline. On PND 125, the sperm count, sperm motility, and the expression of occludin were in recovery. However, there remained significant decreases in these parameters in the 50 mg/kg/d group on PND 125 compared with the control. The dose-related effects on the measured parameters and occludin expression suggest an early suppressive or damaging effect on the blood-testis barrier followed by recovery after dosing ceased. At a BPA dose of 50 mg/kg/d, recovery did not occur, suggesting that higher doses of BPA may cause irreversible damage to reproduction in male mice.

The Effects of l-Carnitine Against Cyclophosphamide-Induced Injuries in Mouse Testis.

In order to explore the possibility of l-carnitine (LC) as a protector of male fertility in chemotherapy, we observed the damage of cyclophosphamide (CTX) to Sertoli cells and the protective effect of LC on the testis Sertoli cells from such damage in this study. Healthy adult male mice were divided into three groups: chemotherapy group were injected intraperitoneally with the CTX; protective agent group were injected both LC and CTX; control group mice were injected only with isochoric physiological saline; all once a day for 5 days. After 5 days, the mice were, respectively, killed at 24 hr after the last injection. The testis and epididymis were removed. Epididymis was for sperm analysis immediately, and immunohistochemistry, RT-PCR and Western blot for the assessments of occludin, glial cell-derived neurotrophic factor (GDNF) and TGF-ß3 mRNA and protein expression. The sperm analysis of epididymis showed that CTX can significantly decrease sperm count and motility; and administration of LC resulted in significant recovery of the sperm count and sperm motility. Compared with control group, the expressions of occludin and GDNF decreased and the expression of TGF-ß3 increased significantly (p < 0.05) in the CTX group. In the LC + CTX group, the expressions of occludin and GDNF were higher than those of the CTX group and similar to those of the control group; the TGF-ß3 expression was lower (p < 0.05) than that of the CTX group and similar to that of the control group. The results of this study showed that CTX could damage the spermatogenesis and reduce the expression of occludin and GDNF, and increase the expression of TGF-ß3 in testis of mouse, which indicates CTX's damage or efficacy to testis Sertoli cells. LC could protect the Sertoli cells of testis from these damages caused by CTX, and promote or protect the spermatogenesis. In conclusion, this study provides meaningful information about the possible damage to male fertility by chemotherapeutics and potential of LC in the protection of male fertility during chemotherapy.
