ABSTRACT
Objective:To investigate the clinical application of free/total prostate-specific antigen (f/tPSA), peripheral blood neutrophil-to-lymphocyte ratio (NLR), interleukin-6 (IL-6) and prostate health index density (PHID) detection in the early diagnosis of prostate cancer.Methods:The clinical data of 160 patients with abnormal prostate specific antigen (PSA) who were admitted to the Second Affiliated Hospital of Xuzhou Medical University from January 2020 to January 2022 were retrospectively analyzed. According to the pathological results of prostate biopsy or electrical resection, the patients were divided into prostate cancer group (68 cases) and benign prostatic hyperplasia group (92 cases), and 50 male healthy physical examiners in the Second Affiliated Hospital of Xuzhou Medical University during the same period were selected as healthy control group. All enrolled members were tested for total prostate-specific antigen (tPSA), free prostate-specific antigen (fPSA), and prostate specific antigen isoform 2 (p2PSA), IL-6 and other indicators, and the f/tPSA, prostate health index (PHI), PHID and NLR were calculated. Receiver operating characteristic (ROC) curve was plotted to compare the efficacy of each index in diagnosing and differentially diagnosing prostate cancer and benign prostatic hyperplasia.Results:The serum levels of tPSA, fPSA, p2PSA, PHI and PHID in the prostate cancer group were higher than those in the benign prostatic hyperplasia group and the healthy control group (all P < 0.05), and the serum f/tPSA was lower than that in the benign prostatic hyperplasia group and the healthy control group ( P < 0.05). The area under the curve (AUC) of PHID for the diagnosis of early stage prostate cancer was the largest [0.915 (95% CI 0.864-0.966)], followed by PHI [0.884 (95% CI 0.823-0.944)]. The sensitivity of both f/tPSA and PHI in diagnosing early stage prostate cancer was 86.80%, which was higher than other indicators; the specificity of PHID in diagnosing early stage prostate cancer was 94.00%, which was higher than other indicators. The AUC of f/tPSA for the diagnosis of benign prostatic hyperplasia was the largest [0.828 (95% CI 0.739-0.917)], followed by PHID [0.826 (95% CI 0.760-0.892)]. The sensitivity of f/tPSA in diagnosing benign prostatic hyperplasia (85.90%) was higher than other indicators, and the specificity of PHI in diagnosing benign prostatic hyperplasia (94.00%) was higher than other indicators. The AUC of fPSA, PHID, f/tPSA and p2PSA in differentiating early stage prostate cancer and benign prostatic hyperplasia were 0.752 (95% CI 0.663-0.841), 0.730 (95% CI 0.647-0.812), 0.713 (95% CI 0.623-0.803), 0.710 (95% CI 0.629-0.791), respectively, and there was no significant difference in each pairwise comparison (all P > 0.05). The sensitivity of NLR in differentiating early stage prostate cancer and benign prostatic hyperplasia was 91.20%, which was higher than other indicators, and the specificity of fPSA in differentiating early stage prostate cancer and benign prostatic hyperplasia was 94.00%, which was higher than other indicators. Conclusions:The f/tPSA, PHI and PHID detection have certain clinical values in the early diagnosis of prostate cancer, and can provide references for early diagnosis, early treatment and prognosis evaluation of high-risk population of prostate cancer.
ABSTRACT
Abstract Objective: Henoch-Schönlein purpura is a systemic vasculitis that mainly occurs in children. Renal impairment is a major complication of Henoch-Schönlein purpura, but there is no established predictive marker for renal involvement. Thus, in this study, we investigated the risk factors for renal involvement in children with Henoch-Schönlein purpura. Method: The medical records of children newly diagnosed as having Henoch-Schönlein purpura between 2005 and 2020 were reviewed retrospectively. Selected laboratory data were recorded before treatment initiation. The date and the age at diagnosis; sex; and the presence of arthralgia, gastrointestinal and renal involvement were obtained retrospectively. Results: This study included a total of 186 patients with Henoch-Schönlein purpura. Among them, 36.0% had renal involvement; 28.4% had only microscopic hematuria, 53.7% had nonnephrotic range proteinuria, and 17.9% had nephrotic-range proteinuria during follow-up. The mean age was higher (p = 0.016) and female sex was predominant (p = 0.001) in patients with renal involvement than in those without renal involvement. Blood neutrophil/lymphocyte ratio (p = 0.002) and platelet/lymphocyte ratio (p = 0.002) were significantly higher than that of the patients without renal involvement. No statistically significant differences were observed in the hemoglobin concentration, platelet count, presence of arthralgia, and gastrointestinal involvement between patients with and without renal involvement. Logistic regression analysis revealed female sex (odd ratio = 3.213) and neutrophil/lymphocyte ratio (odd ratio = 1.329) as risk factors for renal involvement. Conclusions: Female sex and high neutrophil/lymphocyte ratio were risk factors for renal involvement in Henoch-Schönlein purpura.

Antecedentes: La púrpura de Henoch-Schönlein (PHS) es una vasculitis sistémica de vasos pequeños. El objetivo fue evaluar el índice de neutrófilos/linfocitos (INL) en sangre y el volumen plaquetario medio (VPM) en la PHS e investigar la relación con el compromiso renal y gastrointestinal.Métodos: Se incluyeron niños con PHS y controles sanos. Se evaluaron concentración de hemoglobina, recuento de leucocitos, recuento de trombocitos, INL, VPM, velocidad de sedimentación globular y proteína C-reactiva.Resultados: El INL fue significativamente mayor en los pacientes con PHS con hemorragia gastrointestinal (p < 0,001). El valor ideal de corte del INL para predecir la hemorragia gastrointestinal fue 2,05, con 93 % de sensibilidad y 62 % de especificidad. El VPM fue significativamente mayor en los pacientes con PHS con compromiso renal (p = 0,027).Conclusiones: El INL en sangre y el VPM podrían ser útiles para identificar el compromiso renal y gastrointestinal en la PHS
Background: Henoch-Schönlein purpura (HSP) is a systemic small-vessel vasculitis that occurs mainly in children. The aim was to evaluate the blood neutrophil-to-lymphocyte ratio (NLR) and mean platelet volume (MPV) in patients with HSP and to investigate the relationship with gastrointestinal and renal involvement.Methods: Children with HSP and healthy individuals as controls were included. Hemoglobin level, white blood cell count, platelet count, NLR, MPV erythrocyte sedimentation rate and C-reactive protein were evaluated.Results: There were 71 HSP children and 74 controls. NLR was significantly higher in HSP patients with gastrointestinal bleeding than without gastrointestinal bleeding (p < 0,001). The optimal cutoff value of NLR for predicting gastrointestinal bleeding was 2.05, with 93 % sensitivity and 62 % specificity. MPV was significantly higher in HSP patients with renal involvement than without renal involvement (p = 0,027).Conclusions:Blood NLR and MPV may be useful markers to identify gastrointestinal and renal involvement in HSP patients.

Objective To investigate the clinical value of preoperative neutrophil to lymphocyte ratio in predicting lymph node metasta-sis after radical resection of esophageal carcinoma. Methods The clinical data of 110 patients with esophageal carcinoma who underwent radical resection of esophageal carcinoma from February 2015 to March 2017 in our hospital were retrospectively analyzed. NLR≥4 was the critical point,all patients were divided into high NLR group(NLR≥4) in 45 cases,the low NLR group(NLR<4) 65 cases,compared two groups of patients with clinical characteristics,lymph node metastasis,and regression analysis of factors influencing lymph node metastasis af-ter radical resection of esophageal carcinoma by logistic. Results There were 87 patients with lymph node metastasis in 110 cases,among which 43 cases(95. 56％) had lymph node metastasis in 45 cases of high NLR group,and 44 cases(67. 69％) had lymph node metastasis in 65 cases in low NLR group. The number of lymph node metastasis,depth of tumor invasion and distant metastasis in the high NLR group were higher than those in the low NLR group(P<0. 05),which indicated that the preoperative NLR level was related to lymph node metastasis af-ter radical resection of esophageal carcinoma. The number of lymph node metastasis and lymph node metastasis in the high NLR group were higher than those in the low NLR group(P<0. 05). The tumor T stage(OR=1. 898,95％CI:1. 151～3. 130),NLR≥4(OR=1. 919,95％CI:1. 076～3. 422) is the independent risk factors of lymph node metastasis in patients with esophageal cancer(P<0. 05). Conclusion The preoperative NLR was higher in patients with esophageal cancer and its lymph node metastasis,the greater the risk of distant metastasis tumor the deeper the infiltrating,it is more likely,to suggest it should expand the range of lymph node dissection in the operation,the lymph node metastasis,radical dissection has certain value.
