Obstructive sleep apnea(OSA)is a common sleep disorder characterized by repeated episodes of upper airway collapse and obstruction during sleep.Polysomnography is the gold standard for diagnosing OSA,but it is expensive,time-consuming,and can cause discomfort for patients.In recent years,acoustic-based approaches for detecting OSA have emerged as a research focus.This review summarizes recent advances in OSA automatic detection techniques based on snoring and speech signals,and systematically examines their applications in diagnosis,severity assessment,and localization of obstruction sites.Findings indicate that the acoustic features of snoring and speech signals hold significant value for OSA screening,and when combined with machine learning and deep learning models,it can achieve high diagnostic accuracy.Future research should focus on elucidating the relationship between acoustic features and the pathophysiological mechanisms of OSA,integrating multimodal information,and advancing the clinical application of wearable devices,with the aim of promoting intelligent,non-invasive,and cost-effective screening technologies for OSA.

OBJECTIVES: To investigate the active ingredients in Hedyotis diffusa-Scutellaria barbata D. Don and the main biological processes and signaling pathways mediating their inhibitory effect on primary hepatocellular carcinoma (HCC). METHODS: The core intersecting genes of HCC and the two drugs were screened from TCMSP, Uniport, Genecards, and String databases using Cytoscape software, and GO and KEGG enrichment analyses of the intersecting genes were conducted. Molecular docking between the active ingredients of the drugs and the core genes was carried out using Pubcham, RCSB and Autoduckto to identify the active ingredients with the highest binding energy, whose inhibitory effect on HepG2 cells was verifies using CCK-8 assay, flow cytometry and Western blotting. RESULTS: TP53 and ESR1 were identified as the core genes of HCC and the two drugs. GO and KEGG analyses showed that the two genes were mainly involved in regulation of apoptotic signaling pathway, cell population proliferation, methane raft, and protein kinase activity, and participated in the signaling pathways of apoptosis, proteoglycans in cancer, PI3K Akt signaling pathway, and hepatitis B. Molecular docking studies showed that the active ingredients of the drugs could be docked with TP53 and ESR1 genes under natural conditions, and ursolic acid had the highest binding energy to ESR1 (-4.98 kcal/mol). The results of CCK-8 assay, flow cytometry and Western blotting all demonstrated significant inhibitory effect of ursolic acid on HepG2 cells. CONCLUSIONS The inhibitory effect of Hedyotis diffusa-scutellariae barbatae on HCC is mediated by multiple active ingredients in the two drugs.

Objective:To analyze the clinical efficacy of laparoscopic common bile duct exploration and stone removal via the cystic duct with a flexible ureteroscope.Methods:The clinical data of 96 patients with cholecystolithiasis and choledocholithiasis who were admitted to the Department of Hepatobiliary Surgery, the Third Hospital of Nanchang from September 2021 to November 2024 were retrospectively analyzed. There were 49 male and 47 female patients, aged (59.2±13.9) years. The 96 patients were randomly divided into two groups according to the surgical methods: the flexible ureteroscope group ( n=48) and the choledochotomy group ( n=48), patients who underwent laparoscopic cholecystectomy plus flexible ureteroscope for common bile duct exploration and stone removal via the cystic duct were included in the flexible ureteroscope group; patients who underwent laparoscopic cholecystectomy plus choledocholithotomy and T-tube drainage placement were included in the choledochotomy group. Clinical data including operation time, intraoperative blood loss, postoperative intestinal function recovery time, abdominal drainage tube removal time, postoperative hospital stay and postoperative complications were compared between the two groups. Results:Compared with the choledochotomy group, the operation time [150 (120, 176) min vs. 197 (165, 240) min], intraoperative blood loss [20 (10, 30) ml vs. 30 (20, 50) ml], postoperative intestinal function recovery time [2 (1, 2) d vs. 3 (2, 4) d], abdominal drainage tube removal time [6 (4, 7) d vs. 7 (6, 8) d], and postoperative hospital stay [8 (6, 9) d vs. 16 (13, 17) d] in the flexible ureteroscope group were all reduced, and the differences were statistically significant (all P<0.05). The incidence of postoperative complications in the choledochotomy group was 10.4% (5/48), compared with 2.1% (1/48) in the flexible ureteroscope group. There was no statistically significant difference ( χ2=1.60, P=0.206). Conclusion:Compared with laparoscopic choledocholithotomy plus T-tube drainage, laparoscopic common bile duct exploration and stone removal via the cystic duct with a flexible ureteroscope can shorten the hospital stay of patients with choledocholithiasis, offering a minimally invasive, safe and effective treatment method.

Objective:To investigate the postoperative renal function and oncologic outcomes of cystic renal cell carcinoma with partial nephrectomy,and to compared the single-center data on surgical out-comes with the Surveillance,Epidemiology,and End Results(SEER)database.Methods:This was a retrospective study that included the patients with cystic renal cell carcinoma who underwent partial ne-phrectomy in the Department of Urology,Peking University Third Hospital(PUTH)from 2010 to 2023.The clinical data and depicting baseline characteristics were collected.Renal dynamic imaging and the Chinese Coefficients for Chronic Kidney Disease Epidemiology Collaboration(C-CKD-EPI)formulae were used to calculate the estimated glomerular filtration rate(eGFR).The renal function curves over time were then plotted,and the patients were followed-up to record their survival status.Cases of cystic renal cell carcinoma in the SEER database between 2000 and 2020 were included,propensity score matching(PSM)was performed to balance the differences between SEER cohort and PUTH cohort,and the cancer-specific survival(CSS)curves for both groups were plotted and statistical differences were calcu-lated by the Kaplan-Meier method.Results:A total of 38 and 385 patients were included in the PUTH cohort and SEER cohort,respectively,and 31 and 72 patients were screened in each cohort after PSM.Of the baseline characteristics,only tumor size(P=0.042)was found to differ statistically between the two groups.There was no statistically significant difference between the two cohorts in terms of CSS after PSM(P=0.556).The median follow-up time in the SEER cohort was 112.5(65,152)months and a 10-year survival rate of 97.2％,while the PUTH cohort had a median follow-up of 57.0(20,1 172)months and a 10-year survival rate of 100.0％.There was no statistically significant difference between eGFR determined by preoperative renal dynamic imaging and the results of the C-CKD-EPI formulae based on creatinine estimation(P=0.073).There was a statistically significant difference in eGFR among the preoperative,short-term postoperative,and long-term postoperative(P＜0.001),which was characterized by the presence of a decline in renal function in the short-term postoperative period and the recovery of renal function in the long-term period.Conclusion:Partial nephrectomy for cystic renal cell carcinoma is safe and feasible with favorable renal function and oncologic outcomes.

Objective:To systematically evaluate the correlation between chronic periodontitis and postmenopausal osteoporosis (PMOP).Methods:Electronic searches were conducted on Cochrane Library, Pubmed, Embase, Ovid, CNKI, CBM, VIP, and WF databases to collect research literature on the correlation between chronic periodontitis and PMOP. The Newcastle Ottawa Scale (NOS) criteria were used to evaluate the quality of the included literature, and RevMan 5.3 software was used for meta-analysis. The outcome measures were clinical attachment loss (CAL), probing depth (PD), plaque index (PI), calculus index (CI), bleeding on probing (BOP), and simplified oral hygiene index (OHI-S).Results:A total of 16 articles were included, with a total of 1587 patients. Compared with the postmenopausal non osteoporosis group, the osteoporosis group showed significant abnormalities in CAL [standardized mean difference (SMD)=1.09, 95% CI: 0.62-1.57, P<0.001], PD(SMD=0.71, 95% CI: 0.28-1.14, P<0.001), PI(SMD=0.43, 95% CI: 0.29-0.56, P<0.001), and OHI-S(SMD=0.28, 95% CI: 0.22-0.35, P<0.001) indicators, as well as in BOP(SMD=0.01, 95% CI: -0.48-0.49, P=0.97) and GI(SMD=0.01, 95% CI: -0.48-0.49, P=0.97). At the level of 0.24 and 95% CI: -0.34 to 0.81, P=0.42, there was no statistically significant difference. Conclusions:Women with PMOP exhibit more significant changes in indicators such as CAL, PD, PI, and OHI-S, suggesting that postmenopausal women with osteoporosis are more likely to suffer from periodontitis.

Objective:To investigate the construction and application value of a nomogram predictive model for the prognosis of rectal cancer liver metastases based on Surveillance, Epidemio-logy, and End Results (SEER) database.Methods:The retrospective cohort study was conducted. The clinicopathological data of 6 192 patients with rectal cancer liver metastases in the SEER database ( http://seer.cancer.gov/) and 312 patients who were admitted to The Second Affiliated Hospital of Naval Medical University January 2010 to December 2016 were collected. Of 6 192 patients, there were 3 592 males and 2 600 cases. There were 1 076 cases with age lower than 50 years, 2 862 cases with age as 50-69 years, 2 254 cases with age equal to or more than 70 years, respectively. Of 312 pati-ents, there were 177 males and 135 cases. There were 51 cases with age lower than 50 years, 155 cases with age as 50-69 years, 109 cases with age equal to or more than 70 years, respectively. Patients of the SEER database were set as the training set, and patients in The Second Affiliated Hospital of Naval Medical University were set as the validation set. Univariate and multivariate COX proportional hazards regression models were used to analyze risk factors associated with prognosis, and construct and verify the accuracy of nomogram predictive model for the prognosis of rectal cancer liver metas-tasis. The training set were used to construct the nomogram prediction model, and the validation set were used to verify its performance. Observation indicators: (1) prognostic factors analysis in patients with rectal cancer liver metastases; (2) construction and verificative of the predictive model for the prognosis of rectal cancer liver metastasis. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the t test. Count data were described as absolute numbers or percentages, and comparison between groups was conducted using the chi-square test. Comparison of ordinal data was analyzed using the rank sum test. The COX regression model was used for univariate and multivariate analyses. Kaplan-Meier method was used to calculate survival rates, and Log-Rank test was used for survival analysis. Results:(1) Prognostic factors analysis in patients with rectal cancer liver metastases. Results of multivariate analysis showed that age >50 years, TNM Ⅱ-Ⅳ stage, stage T3-T4, stage N1-N2, the number of lymph nodes dissected <12, tumor diameter >5.1 cm, positive carcinoembryonic antigen, peripheral nerve infiltration, radiotherapy and adjuvant chemotherapy, poorly differentiated or undifferented tumor were independent prognostic factors of patients ( P<0.05). (2) Construction and verification of the predictive model for the prognosis of rectal cancer liver metastasis. A nomogram predictive model for the prognosis of rectal cancer liver metastasis was constructed based in the multivariate analysis. The C-index of the nomogram predictive model was 0.91, with area under the curve as 0.726, indicating a good discriminant ability. Results of the calibration curve in validation dataset showed that the colorectal cancer survival rate predicted by the nomogram predictive model was consistent with the actual survival rate. Conclusion:The nomogram predictive model can accurately predict the survival probability of patients with rectal cancer liver metastases.
