ObjectiveTo investigate the intervention effects of modified Linggui Zhugan Tang (LGZGT) on patients with obstructive sleep apnea-hypopnea syndrome (OSAHS) of the spleen deficiency and dampness obstruction with blood stasis type, reveal its possible mechanisms, and provide a theoretical basis for the clinical treatment of OSAHS with traditional Chinese medicine (TCM). MethodsEighty OSAHS patients with spleen deficiency and dampness obstruction with blood stasis were randomly assigned to a control group and an observation group (1∶1) using a random number table, with 40 patients in each group. The control group received standard basic treatment combined with oral Doxofylline tablets, while the observation group received standard basic treatment combined with modified LGZGT. Serum levels of macrophage migration inhibitory factor (MIF), microRNA-223 (miR-223), and interleukin-18 (IL-18) were measured by enzyme-linked immunosorbent assay (ELISA), and the mRNA expression levels of MIF, miR-223, and IL-18 were measured by real-time quantitative polymerase chain reaction (Real-time PCR). After two months of treatment, the total clinical efficacy, apnea-hypopnea index (AHI), lowest nocturnal oxygen saturation (LSpO2), body mass index (BMI), TCM syndrome scores, and expression levels of MIF, miR-223, and IL-18 before and after treatment were compared between the two groups. Correlations between MIF, miR-223, IL-18 and AHI and LSpO2 were also analyzed. ResultsCompared with the control group, the observation group showed a significantly higher total clinical effective rate (P<0.01, Z=-3.49). Within the control group, no significant changes were observed in AHI, LSpO2, BMI, TCM syndrome scores, or MIF, miR-223, IL-18 levels and their mRNAs after treatment. In the observation group, AHI, BMI, TCM syndrome scores, and MIF and IL-18 levels and their mRNAs decreased significantly, while LSpO2 increased significantly (P<0.01). After treatment, compared with the control group, the observation group exhibited significantly lower AHI, BMI, TCM syndrome scores, and MIF and IL-18 levels and their mRNAs, and significantly higher LSpO2 (P<0.01). Correlation analysis showed that MIF and IL-18 were positively correlated with AHI (P<0.01) and negatively correlated with LSpO2 (P<0.01), whereas miR-223 was negatively correlated with AHI (P<0.01) and positively correlated with LSpO2 (P<0.01). ConclusionModified LGZGT may improve OSAHS of the spleen deficiency and dampness obstruction with blood stasis type by reducing airway inflammatory factors, alleviating airway inflammation, relieving airway edema and stenosis, and improving airway obstruction.

Objective:To explore the independent factors influencing extraprostatic extension (EPE) after radical prostatectomy(RP) in patients with clinically localized prostate cancer by utilizing the Surveillance, Epidemiology, and End Results (SEER) database. A nomogram model was developed and externally validated.Methods:Clinical and pathological data of 20 916 clinically localized prostate cancer patients (T 1-2N 0M 0) who underwent RP between 2010 and 2021 were extracted from the SEER database. The mean age was (61.71±7.09) years old, and a total of 17 835 patients (85.3%) were married.There were 2 243 patients (10.7%) with prostate-specific antigen (PSA) <4 ng/ml, 14 831 patients (70.9%) with ≥4 and <10 ng/ml, and 2 965 patients (14.2%) with ≥10 and <20 ng/ml. There were 14 870 patients (71.1%) with clinical staging of stage T 1, and 6 046 patients (28.9%) with T 2. There were 48 patients (0.2%) with pathological staging of stage T 1, 15 794 (75.5%) with T 2, 5 001(23.9%) with T 3, and 73 (0.3%) with T 4 stage after radical surgery.The patients of SEER database were divided into training and internal validation groups in a 7∶3 ratio by using stratified sampling. Additionally, data were collected for 75 clinically localized prostate cancer patients who underwent RP at the Second Affiliated Hospital of Zhengzhou University from September 2019 to September 2024, serving as the external validation group.The mean age was(65.39±7.45) years old. Among them, 73 (97.3%) were married. There were 2 patients (2.7%) with PSA <4 ng/ml, 17 patients (22.7%) with ≥4 and <10 ng/ml, and 34 patients (45.3%) with ≥10 and <20 ng/ml. There were 47 patients (62.7%) with clinical staging of stage T 1, and 28 patients (37.3%) with T 2. There were 7 patients (9.3%) with pathological staging of stage T 1, 48 patients (64.0%)with T 2, 18 patients (24.0%) with T 3, and 2 patients (2.7%) with T 4 stage after radical surgery. All patients were categorized into organ-confined (OC) and EPE groups based on post-surgical pathology. Univariate and multivariate logistic regression analyses, with a stepwise backward selection, were performed on the training group to identify independent risk factors of EPE, which were used to construct a nomogram model. Model performance was assessed using receiver operating characteristic (ROC) curve area under the curve (AUC), calibration curves, and decision curve analysis (DCA) for the training group, internal validation group, and external validation group. Results:EPE was observed in 3 585 cases (24.5%), 1 489 cases (23.8%), and 20 cases (26.7%) in the training, internal validation, and external validation groups, respectively. Logistic regression analyses identified preoperative age ( OR=1.026, P<0.001), PSA levels (≥10 and <20 ng/ml: OR=1.790, P<0.001; ≥20 ng/ml: OR=2.683, P<0.001), tumor maximum diameter (10-20 mm: OR=2.051, P<0.001; >20 mm: OR=3.937, P<0.001), biopsy Gleason score (score 7: OR=1.911, P<0.001; score 8: OR=2.906, P<0.001; score 9: OR = 5.278, P<0.001; score 10: OR=4.421, P=0.003), number of positive biopsy cores (≥4 cores: OR=1.260, P<0.001), and their proportion of total cores ( OR=1.012, P<0.001) as independent predictors of EPE. The nomogram model demonstrated good predictive performance, with AUC of 0.741, 0.748, and 0.724 in the training, internal validation, and external validation groups, respectively. Calibration and DCA curves confirmed the model’s excellent stability and generalizability. Conclusions:Age, PSA levels, maximum tumor diameter, biopsy Gleason score, number of positive biopsy cores, and their proportion of total cores are independent predictors of EPE after RP in clinically localized prostate cancer. The constructed model effectively predicts the risk of EPE occurrence.

Objective:To investigate the application value of combining Prostate Imaging Reporting and Data System (PI-RADS v2.1) score and Systemic Immune-Inflammation Index (SII) in predicting pathological upgrading in patients with localized prostate cancer after radical prostatectomy(RP).Methods:A retrospective analysis was conducted on clinical data from 76 patients with localized prostate cancer who underwent prostate biopsy and radical prostatectomy at the Second Affiliated Hospital of Zhengzhou University between September 2019 and May 2024. The median age was 68 (65, 71) years. Total prostate-specific antigen (tPSA) was 17.4 (8.4, 30.9) ng/ml, and prostate volume was 43.1 (29.9, 58.9) ml. PI-RADS scores were ≤3 in 22 cases (28.9%) and >3 in 54 cases (71.1%). According to the International Society of Urological Pathology (ISUP) grading of biopsy specimens, 31 patients (40.8%) were classified as Group <3 and 45 patients (59.2%) as Group ≥3. Postoperatively, 25 patients (32.9%) were classified as ISUP Group <3, and 51 patients (67.1%) as Group ≥3. Pathological upgrading was defined as either: ①a higher ISUP grade in postoperative specimens compared to biopsy specimens or; ②benign prostate tissue identified in biopsy specimens but confirmed as prostate cancer postoperatively. Clinical data were compared between the pathological upgrade and non-upgrade groups. Univariate and multivariate logistic regression analyses were performed to identify independent risk factors for pathological upgrading and to construct a nomogram model. Receiver operating characteristic (ROC) curves were used to evaluate the predictive performance of individual indicators (PI-RADS, SII, %PSA, and the proportion of tumor tissue in biopsy specimens) and the combined nomogram model. Internal validation was conducted using cross-validation, and calibration and decision curves were generated to assess the nomogram′s accuracy and clinical net benefit.Results:Among the 76 patients included, 10 (13.2%) experienced pathological downgrading, 36 (47.4%) had consistent grading, and 30 (39.5%) experienced pathological upgrading. The platelet-to-lymphocyte ratio (PLR) [118.2(93.5, 139.1) vs. 95.2(79.3, 116.4), P=0.021], SII [394.8(331.0, 513.6) vs. 338.8(217.2, 407.8), P=0.002], and the number of cases with a PI-RADS score >3 [26 cases(86.7%) vs. 28 cases(60.9%), P=0.015] were significantly higher in the pathological upgrade group than in the non-upgrade group. Conversely, the percentage of positive biopsy cores [35.9%(12.6%, 51.8%) vs. 43.8%(21.0%, 92.1%), P=0.045], the proportion of tumor tissue in biopsy specimens [6.9%(1.3%, 20.1%) vs. 19.3%(9.1%, 58.4%), P<0.01], and the number of cases in ISUP biopsy Group ≥3 [12 cases (40.0%) vs. 33 cases (71.7%), P=0.006] were significantly lower in the upgrade group (all P < 0.05). Univariate and multivariate logistic regression analyses showed that PI-RADS score( OR=17.111, 95% CI 2.388-122.592, P<0.01), SII( OR=1.009, 95% CI 1.001-1.016, P=0.028), %PSA ( OR=0.003, 95% CI 0.002-0.004, P<0.01), and the proportion of tumor tissue in biopsy specimens ( OR=0.899, 95% CI 0.837-0.966, P<0.01) were independent predictors of pathological upgrading. The area under the ROC curve (AUC) for PI-RADS, SII, %PSA, and the proportion of tumor tissue in biopsy specimens were 0.607, 0.711, 0.618, and 0.778, respectively. The combined AUC for %PSA and the proportion of tumor tissue was 0.791, while the combined AUC of the four-indicator nomogram model was 0.914. The DeLong test indicated a statistically significant difference in diagnostic performance between the two models ( P<0.01). Calibration and decision curves demonstrated good accuracy and clinical net benefit for the nomogram model. Conclusions:The PI-RADS v2.1 score and SII have significant predictive value for pathological upgrading after radical prostatectomy in prostate cancer. A nomogram model combining PI-RADS, SII, %PSA, and the proportion of tumor tissue in biopsy specimens shows excellent predictive performance.

Objective:To investigate the changes of dynamic functional brain network connectivity in patients with Parkinson disease(PD) using Hidden Markov model(HMM), and to analyze the correlation between dynamic functional parameters and clinical parameters.Methods:Forty-eight PD patients(PD group) and thirty-three healthy controls(HC group) were included from 2019 to 2023. The cognitive function was assessed using the Montreal cognitive assessment (MoCA), and motor status was assessed using the unified Parkinson's disease rating scale Ⅲ(UPDRS-Ⅲ) in PD group.HMM technique was used to analyze the dynamic functional brain network connectivity, and the dynamic higher-order index fractional occupancy(FO), switching rate(SR), and mean dwell time(MDT) were obtained. Two independent samples t-test was used to calculate the differences between groups of functional connectivity matrices in different states, and Mann-Whitney U test was used to calculate the differences between groups of dynamic higher-order indicators in different states. Spearman correlation analysis was used to calculate the correlation between dynamic higher-order parameters and clinical parameters in the PD group. Results:The HMM was used to construct 6 spatial states for all subjects.MDT was significantly higher in PD group(24.93(19.73)) in state 1 sparse junctions than that in HC group(17.63(14.80)) ( Z=-2.030, P=0.042), but significantly lower MDT was showed in PD group(6.00(3.00)) in state 5 tight junctions than that in HC group(9.75(7.70)) ( Z=-2.210, P=0.027).FO in state 3 was negatively correlated with MoCA score in PD group( r=-0.331, P=0.022).FO in state 5 was positively correlated with UPDRS-Ⅲ score in PD patients( r=0.412, P=0.004), and MDT in state 5 was positively correlated with UPDRS-Ⅲ score( r=0.448, P=0.001). Conclusion:HMM can capture the transient changes of dynamic brain network, which can provide some value for the study of dynamic brain network in patients with Parkinson disease.

The DeLong test indicated a statistically significant difference in diagnostic performance between the two models ( P<0.01). Calibration and decision curves demonstrated good accuracy and clinical net benefit for the nomogram model. Conclusions:The PI-RADS v2.1 score and SII have significant predictive value for pathological upgrading after radical prostatectomy in prostate cancer. A nomogram model combining PI-RADS, SII, %PSA, and the proportion of tumor tissue in biopsy specimens shows excellent predictive performance.
