Objective:To summarize the clinical characteristics of elderly patients with stage Ⅰ diffuse large B-cell lymphoma (DLBCL) and analyze the factors associated with prognosis.Methods:A case series study was conducted by retrospectively collecting clinical data from patients aged over 60 years with newly diagnosed stage Ⅰ DLBCL across 20 medical centers in Jiangsu Province, China, between June 2010 and April 2023. The involved site, classification and treatment plan were summarized. The primary endpoints were progression-free survival (PFS) and overall survival (OS). Statistical analyses were performed using the Kaplan-Meier method, and Cox regression model.Results:The study included 255 patients with a median age of 69 years, of whom 130 (51.0%) were male, 66 (25.9%) were aged ≥75 years and 26 (10.1%) had a high Charlson Comorbidity Index (CCI) score of ≥2. Extranodal involvement was observed in 163 (63.9%) patients, with the stomach (37.4%, 61/163), intestine (19.0%, 31/163), testes (11.0%, 18/163), and breast (7.4%, 12/163) being the most frequently affected sites. The non-germinal center B-cell (non-GCB) subtype was prevalent in 63.7% of patients (142/223), with no significant difference between the nodal and extranodal groups ( P=0.681). Furthermore, 73.9% (184/249) and 11.7% (29/249) of patients received the R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, prednisone) and R-miniCHOP regimen, respectively. The overall 3-year PFS rate was 81.5%, and the 3-year OS rate was 85.6%. Patients aged ≥75 years ( HR=2.910, 95% CI 1.565-5.408, P=0.001) and/or with a CCI score ≥2 ( HR=2.324, 95% CI 1.141-4.732, P=0.020) had a significantly poorer PFS. Incorporating age ≥75 years and CCI score ≥2 into the stage-modified international prognostic index (sm-IPI) can better stratify the prognosis of elderly patients with stage Ⅰ DLBCL. The 3-year PFS rate was 48.7% in the high-risk group versus 85.7% in the low-risk group ( P<0.001). Conclusions:Our findings show that the elderly patients with stage Ⅰ DLBCL were predominantly characterized by extranodal involvement (particularly in the stomach and intestinal tract) and non-GCB subtype. Age ≥75 years and CCI ≥2 were identified as independent prognostic factors. The newly established sm-IPI-75-CCI incorporating these factors demonstrated superior prognostic discrimination compared to conventional risk assessment systems.

Objective To analyze the gonadal hormone and seminal plasma of patients with abnormal semen liquefaction and investigate the influence mechanism in order to provide guidance for the diagnosis and treatment. Methods 152 men of childbearing age were divided into two groups according to the liquefaction time (cut?off point: 60 minutes). Routine semen parameters,gonadal hormone and seminal plasma were tested and compared between the above groups. T?test was applied to compare individual gland function (pH value,neutralα?glycosidase,fructopyranose,seminal plasma zinc and citric acid) and gonadal hormone (FSH,LH,PRL,T and E2). Logistic regression analysis was adopted to probe the influencing factors for abnormal semen liquefaction. Results Seminal pH value (7.47 ± 0.13 vs. 7.32 ± 0.18),citric acid(51.12 ± 12.95 vs. 83.11 ± 33.46)and FSH (4.40 ± 1.03 vs. 4.85 ± 1.50)levels were significant different between the two groups (P < 0.05),but the other indexes showed no significant difference. Correlation regression analysis showed that semen liquefaction capacity has correlative relationship with seminal plasma fructose (OR=2.644),citric acid (OR=0.922),serum T (OR=1.029) and E2,while no correlative relationship with other indexes. Conclusions Correlation between two glands (seminal vesicle and prostate) and balance in the two hormones (T and E2) influence the liquefaction time. Specific causes should be distinguished before diagnosis.

Objective To evaluate the value of serum E2 levels during COH in predicting IVF-ET outcome. Method Data from 311 IVF-ET cycles received long protocol were collected and analyzed according to E 2 levels 5 days after stimulation:Group A (E2≤500 pmol/L), Group B (500 2 000 pmol/L). Results In groups with E2>1 000 pmol/L, the conditions of oocyte and embryo are higher than E2<1 000 pmol/L. With the increase of E2 levels, period cancellation rate increases. When E2> 2 000 pmol/L, the pregnancy rate become lowest. Conclusion E2 levels among 1 000~1 500 pmol/L during early COH predicts a better pregnancy outcome.

Objective To compare the effect of kidney-tonifying blood-activating recipe (KBR) and Aescuven Forte Tablets ( AFT) in improving the sperm quality of varicocele-induced male sterility, thus to optimize the therapeutic therapy for varicocele-induced male sterility. Methods A total of 102 varicocele-induced male sterility with abnormal sperm parameters after conservative treatment were randomized into KBR group (N=53) and AFT group ( N=49) . KBR group was given KBR plus natural vitamin E and AFT group was given AFT plus natural vitamin E, and the treatment lasted for 8 continuous weeks. Before and after treatment, the quality of seminal fluid was analyzed, sperm quantization parameters such as total number of sperm (TNS) , total number of progressive motility sperm ( TNPS) , total number of normal form sperm ( TNNS) and total number of nor mal form and progressive motility sperm ( TNNPS) were observed, and the improvement rate of sperm quantization parameter was compared. Results (1) Before treatment, the differences of TNS, TNPS, TNNS and TNNPS were insignificant between the two groups ( P>0.05) . After treatment, TNNS was not improved in AFT group ( P>0.05) , but TNS, TNPS, TNNPS were much improved in both groups ( P<0.01 compared with those before treatment) . The improvement of KBR group was superior to that of AFT group ( P<0.05) . ( 2) The improvement rate for TNS, TNPS, TNNS, TNNPS was 90.57%, 79.25%, 67.92%, 77.36%in KBR group, and was 75.51%, 73.47%, 28.57%, 61.22% in AFT group respectively. The improvement rate for TNS and TNNS in KBR group was superior to that in AFT group ( P<0.05 or P<0.01) . Conclusion Varicocele-induced male sterility patients usually have the syndrome of kidney deficiency and blood stasis, so KBR, which has the function of tonifying kidney and activating blood, has synergistic action on the effect of AFT in improving sperm quality of varicocele-induced male sterility patients.
