Objective: To establish an accurate and rapid typing method for Rh typing of samples from patients who have received recent blood transfusions by utilizing the difference in osmotic fragility between fresh and old red blood cells. Methods: A lysing solution suitable for destroying old RBCs was prepared. Sixty-one samples collected in our hospital in 2024 with Rh typing of double groups were treated with the lysing solution to remove the old allogeneic red blood cells while preserving the patient's own fresh red blood cells, followed by repeat Rh typing tests. Results: For 61 samples with Rh typing in double groups, 41 were accurately detected identified through the red blood cell lysis method, yielding an identification rate of 67.21%. No significant difference was observed compared to the detection rate of the commonly used capillary centrifugation modified method (χ
=0.103, P>0.05). Conclusion: The red blood cell lysis method provides a novel and rapid experimental approach for clinical use in processing Rh-typed samples that are of double groups, thereby offering a basis for Rh compatibility blood transfusion.

Chronic epididymitis (CE) is a long-standing inflammatory condition of the epididymis caused by unresolved acute infections, chronic infections, medication use, or other factors. Clinically, it is characterized by persistent dull pain or a dragging sensation in one or both sides of the scrotum. The disease course typically exceeds three months and is marked by insidious onset and recurrent episodes. Current studies suggest that CE may disrupt the epididymal microenvironment through multiple pathological processes, including local inflammatory responses, oxidative stress, fibrotic remodeling, and autophagy. These alterations impair sperm maturation, transport, and capacitation, thereby contributing to male reproductive dysfunction and infertility. This review summarizes the major etiologies and pathophysiological characteristics of CE and its impact on male reproductive function. It focuses on the roles of inflammatory cytokines and related signaling pathways, oxidative stress mechanisms, and fibrotic progression in the pathogenesis of CE. Moreover, it explores targeted therapeutic strategies based on these mechanisms, aiming to provide a theoretical basis for identifying key molecular targets and signaling pathways involved in CE-induced male reproductive impairment.

Depressive disorder is a kind of mental disorder characterized by persistent and significant depressed mood, with complex etiology and high recurrence rate. At present, more precise and effective diagnostic and therapeutic approaches are still required. Increasing evidence suggests that hypoxia inducible factor-1 (HIF-1) and related pathways are involved in regulating the development and recovery of depression. HIF-1 enhances neuroplasticity, mitigates neuroinflammatory responses, alleviates oxidative stress, and modulates brain energy metabolism by influencing specific molecules associated with depression. This paper reviews pertinent domestic and international studies, examine the potential mechanisms of HIF-1 in the pathogenesis and progression of depression, and explore antidepressant treatment strategies targeting the HIF-1 signaling pathway. This article provides novel insights into elucidating the pathogenesis of depression and developing innovative therapeutic approaches.

Objective:To explore the rehabilitation effects of individual computer story-version magnanimous therapy (ICSMT) on patients with end-stage renal disease undergoing maintenance hemodialysis (MHD).Methods:A total of 120 patients with end-stage renal disease receiving MHD treatment at the Department of Nephrology Hemodialysis Center of Huadu District People's Hospital of Guangzhou from August 2022 to April 2024 were selected as the study subjects.They were randomly divided into control group ( n=60, receiving routine clinical treatment) and ICSMT group ( n=60, receiving routine clinical treatment combined with ICSMT for psychological intervention) by random number table method.The patients in the two groups were evaluated by the self-rating anxiety scale (SAS), self-rating depression scale (SDS), enterprising and magnanimous questionnaire (EMQ), the short-form-36 health survey (SF-36), and activity of daily living scale (ADL) before intervention and at 4-week post-intervention.Blood pressure, blood urea nitrogen (BUN), hemoglobin (Hb), and serum albumin (ALB) levels were also measured before the intervention and at the 4-week post-intervention.The clinical global impression scale (CGI) was used to evaluate clinical efficacy before the intervention, at the 2-week post-intervention, and at the 4-week post-intervention.Statistics analysis was performed using SPSS 29.0.1.0(171). Independent-samples t-test, paired t-test, Mann-Whitney U test and Wilcoxon signed-rank test were used for statistical analysis. Results:After 4 weeks of intervention, the SAS and SDS in the ICSMT group (49.0 (48.0, 50.0), 50.0 (49.0, 51.0)) were significantly lower than those in the control group (51.0 (50.0, 52.0), 52.0 (51.0, 53.0)) (both P<0.001). The enterprising subscore of the EMQ in the ICSMT group (35.0 (32.0, 37.0)) was significantly higher than that in the control group (31.0 (29.0, 34.0)) ( P<0.001). Furthermore, the differences of enterprising and magnanimous subscores between the two groups before and after intervention in the ICSMT group (2.0 (1.0, 4.0), 1.0 (-1.0, 2.0))were significantly higher than those in the control group (-1.0 (-1.0, 0), -1.0 (-1.2, 0)) (both P<0.05). Systolic and diastolic blood pressure values in the ICSMT group (130 (126, 134) mmHg, 85 (80, 88) mmHg)were significantly lower than those in the control group (145 (138, 152) mmHg, 93 (88, 99) mmHg)(1 mmHg=0.133 kPa) after 4 weeks of intervention(both P<0.05). After 4 weeks of intervention, the level of BUN in the ICSMT group (5.5 (3.7, 8.4) mmol/L) was significantly lower than that in the control group (9.1 (6.8, 11.4) mmol/L), while the level of Hb and ALB in the ICSMT group ((115.0±10.0)g/L, (38.3±3.2)g/L)were significantly higher than those in the control group ((104.0±12.0)g/L, (37.1±2.9)g/L) (all P<0.05). After 4 weeks of intervention, the physical functioning, role-physical, general health, vitality, social functioning, role-emotional, and mental health subscores of SF-36 in ICSMT group were all significantly higher than those in the control group (all P<0.05). After 4 weeks of intervention, the score of ADL in the ICSMT group (15.42±1.58)was significantly lower than that in the control group (16.78±2.06) ( t=-4.08, P<0.05). At the 2-week post-intervention and the 4-week post-intervention, the severity of illness (SI) and global improvement (GI) in the ICSMT group were significantly lower than those in the control group, while the efficacy index (EI) in the ICSMT group was significantly higher than that in the control group (all P<0.05). Conclusion:ICSMT can effectively promote the physical, psychological, and social functional rehabilitation of end-stage renal disease patients undergoing MHD, significantly improving their quality of life.
