RESUMEN

OBJECTIVE: Renal calculi are solid crystals that form in the kidneys and cause severe pain and discomfort. This study aims to investigate risk factors for postoperative recurrence of renal calculi in elderly patients and provide background knowledge on the prevalence and management of renal calculi in this demographic. METHODS: The clinical data of 123 elderly patients with renal calculi were included from 1 June 2021 to 1 June 2023 for their 6-month follow-up study. The patients were divided into recurrence group and non-recurrence group according to whether they had recurrence after surgery. The general sociological characteristics and disease-related characteristics of the two groups were counted. Logistic regression equation was used to calculate differences, and the influencing factors of postoperative recurrence in elderly patients with kidney stones were obtained. A receiver operating characteristic (ROC) curve was drawn to analyse the value of the factors in predicting postoperative recurrence in patients with kidney stones. RESULTS: A total of 123 elderly patients with renal calculi were enrolled. The patients were divided according to the presence or absence of stone recurrence into the recurrence group (25 cases, 20.33%) and the non-recurrence group (98 cases, 79.67%). Postoperative water intake, excessive intake of animal protein, exercise and postoperative complications significantly differed between the recurrence group and the non-recurrence group (p < 0.001). Logistic regression analysis showed that the above-mentioned indicators were the influencing factors of postoperative recurrence. The area under the curve (AUC) values of postoperative water intake (AUC = 0.767), animal protein intake (AUC = 0.752), exercise (AUC = 0.707) and postoperative complications (AUC = 0.727) were statistically significant, and they were identified as the most important factors with high sensitivity and specificity and were of high value in predicting postoperative recurrence of renal calculi. CONCLUSIONS: Elderly patients with kidney stones are prone to recurrence after surgery. Influencing factors should be given attention, and corresponding measures should be formulated for intervention as soon as possible.

RESUMEN

OBJECTIVES: To explore the effects of a 'Rebuilding Myself' intervention on enhancing the adaptability of cancer patients to return to work. METHODS: A single-center, single-blind, randomized controlled trial design was used. Eligible patients who were receiving routine hospital treatment were recruited from the university-affiliated hospital in our city. Patients in the control group only received usual care, while patients in the intervention group received additional 'Rebuilding Myself' intervention. Adaptability to return to work, self-efficacy of returning to work, mental resilience, quality of life and work ability were measured at baseline, the 6th and 12th of the intervention. The general estimation equations were used to compare the overall changes of each outcome index between the two groups at different time points. Considering that there may be patient shedding and rejection, Per-Protocol and Intention-to-Treat analysis were used to analyze the data in this study. RESULTS: There were statistically significant differences between the two groups of patients in the cancer patients' adaptability to return to work, self-efficacy to return to work, mental resilience, work abilities, the physical, emotional, cognitive function, fatigue, insomnia and overall health status dimensions of quality of life (P < 0.05). And no significant difference was found in other dimensions (P > 0.05). The group effect, time effect, and interaction effect of patients' return to work adaptability and return to work self-efficacy were statistically significant in both groups (P < 0.05). Mental resilience, working ability, and quality of life had obvious time effect and interaction effect (P < 0.05). CONCLUSION: This intervention could improve cancer patients' adaptability to return to work, self-efficacy to return to work, mental resilience, work abilities and quality of life. And it can be further expanded to improve the adaptability of patients to return to work, then to help patients achieve comprehensive rehabilitation. IMPLICATIONS FOR CANCER SURVIVORS: The application of 'Rebuilding Myself' interventions can effectively improve the adaptability of cancer patients returning to work. TRIAL REGISTRATION: This study was registered at the Chinese Clinical Trial Registry (Registration number: ChiCTR2200057943) on 23 March, 2022.

RESUMEN

BACKGROUND: Obstructive sleep apnea hypopnea syndrome (OSAHS) refers to the apnea and hypopnea caused by partial or complete obstruction of the upper airway collapse during sleep. The cryogenic plasma tonsillectomy is mostly used for the clinical treatment of children with OSAHS. AIMS: The objective of this meta-analysis is to investigate the clinical efficacy of cryogenic plasma tonsillectomy for OSAHS in children. MATERIALS & METHODS: The literature search was conducted through China National Knowledge Infrastructure (CNKI), Wanfang Database, Embase, PubMed, and Web of Science databases. The search was from the establishment of each database to June 2022. Randomized controlled trials (RCTs) meeting the criteria for partial/total cryo-plasma tonsillectomy for treating patients with obstructive sleep apnea-hypopnea syndrome in children were included, with data extracted. The meta-analysis was performed using the Stata 16.0 and Review Manager 5.4. Seven RCTs were included in this study. RESULTS: The results showed that the partial/complete cryo-plasma tonsillectomy in the experimental group had a better therapeutical effective rate than the control group of patients treated with conventional surgery [Odds ratio (OR) = 2.181, 95% CI: 1.306-3.645, P < 0.05]. Also, in terms of postoperative adverse reactions, the number of adverse reactions in the experimental group was significantly lower than in the control group (OR = 0.445, 95% CI: 0.287-0.689, P = 0.001). The analysis of surgical efficacy showed that the operative time, intraoperative blood loss, and postoperative pain score were all significantly lower than those of the control group. Furthermore, further analysis of the apnea-hypopnea index (AHI) and the lowest oxygen saturation (LSaO2) of the two groups showed that the cryo-plasma tonsillectomy treatment had higher LSaO2 levels than conventional treatment [Standardized mean difference (SMD) = 0.380, 95% CI: 0.094-0.667, P = 0.009]. CONCLUSION: The application of cryo-plasma tonsillectomy can significantly improve the treatment effect of OSAHS, reducing adverse reactions.

RESUMEN

BACKGROUND: Circular RNAs (circRNAs) are key regulators in oncogenesis and chemoresistance of human cancers. Herein, we focused on the roles of circ_0002360 in regulating lung cancer progression and cisplatin (DDP) resistance. METHODS: The detection of circ_0002360, microRNA-6751-3p (miR-6751-3p) and zinc finger protein 300 (ZNF300) was conducted via reverse transcription-quantitative polymerase chain reaction assay. Cell sensitivity was determined using cell counting kit-8 assay. Proliferation detection was performed by colony formation assay and EdU assay. The migrated cells were examined via transwell assay. Cell apoptosis analysis was carried out through flow cytometry and caspase 3 activity assay. Western blot was used to examine the protein levels. Target interaction was confirmed through dual-luciferase reporter assay and RNA immunoprecipitation assay. Circ_0002360 function in vivo was performed via xenograft tumor assay. RESULTS: Circ_0002360 was overexpressed in DDP-resistant lung cancer tissues and cells. Silencing circ_0002360 inhibited DDP resistance, proliferation and migration but enhanced apoptosis of DDP-resistant cells. Circ_0002360 could elevate ZNF300 expression. DDP resistance and lung cancer progression were also impeded by ZNF300 downregulation. ZNF300 overexpression reversed the function of circ_0002360 knockdown in DDP-resistant lung cancer cells. The regulation of circ_0002360 for ZNF300 was achieved by sponging miR-6751-3p. Circ_0002360 promoted DDP resistance in xenograft mice through mediating the miR-6751-3p/ZNF300 axis. CONCLUSION: Circ_0002360 targeted miR-6751-3p to regulate ZNF300 level, thus elevating DDP resistance and promoting the malignant progression of lung cancer cells.

RESUMEN

Dysregulation of the cell cycle and the resulting aberrant cellular proliferation has been highlighted as a hallmark of cancer. Certain traditional Chinese medicines can inhibit cancer growth by inducing cell cycle arrest. In this study we explore the effect of Hedyotis diffusae Herba-Andrographis Herba on the cell cycle of nasopharyngeal carcinoma (NPC). Hedyotis diffusae Herba-Andrographis Herba-containing serum was prepared and then added to the cell culture medium. BrdU, comet, and FUCCI assays, western blot analysis and flow cytometry analysis revealed that Hedyotis diffusae Herba-Andrographis Herba treatment significantly alters cell proliferation, DNA damage, and cell cycle distribution. Xenograft mouse model experiments were performed, confirming these in vitro findings in vivo. Treatment with Hedyotis diffusae Herba-Andrographis Herba inhibited cell proliferation, promoted DNA damage, and arrested NPC cells progression from G1 to S phase. Further examination of the underlying molecular mechanisms revealed that treatment with Hedyotis diffusae Herba-Andrographis Herba increased the expression of p53 and p21, while reducing that of CCND1, Phospho-Rb, E2F1, γH2AX, and Ki-67 both in vivo and in vitro. Conversely, the inhibition of p53 and p21 could abolish the promoting effect of Hedyotis diffusae Herba-Andrographis Herba on the NPC cell cycle arrest at the G1 phase, contributing to the proliferation of NPC cells. Hedyotis diffusae Herba-Andrographis Herba suppressed the tumor growth in vivo. Overall, these findings suggest that Hedyotis Diffusae Herba-Andrographis prevent the progression of NPC by inducing NPC cell cycle arrest at the G1 phase through a p53/p21-dependent mechanism, providing a novel potential therapeutic treatment against NPC.

RESUMEN

Prostate cancer (PCa) is a highly aggressive malignant tumor and the biological mechanisms underlying its progression remain unclear.We performed weighted gene co-expression network analysis in PCa dataset from the Cancer Genome Atlas database to identify the key module and key genes related to the progression of PCa. Furthermore, another independent datasets were used to validate our findings.A total of 744 differentially expressed genes were screened out and 5 modules were identified for PCa samples from the Cancer Genome Atlas database. We found the brown module was the key module and related to tumor grade (R2 = 0.52) and tumor invasion depth (R2 = 0.39). Besides, 24 candidate hub genes were screened out and 2 genes (BIRC5 and DEPDC1B) were identified and validated as real hub genes that associated with the progression and prognosis of PCa. Moreover, the biological roles of BIRC5 were related to G-protein coupled receptor signal pathway, and the functions of DEPDC1B were related to the G-protein coupled receptor signal pathway and retinol metabolism in PCa.Taken together, we identified 1 module, 24 candidate hub genes and 2 real hub genes, which were prominently associated with PCa progression. With more experiments and clinical trials, these genes may provide a promising future for PCa treatment.

RESUMEN

Applying the iterative stitching algorithm, we demonstrate the power of subaperture testing through experiments. Naturally the algorithm applies to flats, spherical or aspheric surfaces. We first apply it to a silicon carbide flat mirror with larger aperture than the interferometer's. The testing results help to obtain a high-precision mirror through five iterations of ion beam figuring. The second experiment is 37-subaperture testing of a large spherical mirror. Good consistence is observed between the stitching result and the full aperture test result using a Zygo interferometer. Finally we study the applicability of the algorithm to subaperture testing of a parabolic surface. The stitching result is consistent with the auto-collimation test result. Furthermore, the surface is tested with annular subapertures and also retrieved by our algorithm successfully.
