Objective: The CT/MRI Liver Imaging Reporting and Data System (LI-RADS) demonstrates high specificity with relatively limited sensitivity for diagnosing hepatocellular carcinoma (HCC) in high-risk patients. This study aimed to explore the possibility of improving sensitivity by combining CT/MRI LI-RADS v2018 with second-line contrast-enhanced ultrasound (CEUS) LI-RADS v2017 using sulfur hexafluoride (SHF) or perfluorobutane (PFB). Materials and Methods: This retrospective analysis of prospectively collected multicenter data included high-risk patients with treatment-naive hepatic observations. The reference standard was pathological confirmation or a composite reference standard (only for benign lesions). Each participant underwent concurrent CT/MRI, SHF-enhanced US, and PFB-enhanced US examinations. The diagnostic performances for HCC of CT/MRI LI-RADS alone and three combination strategies (combining CT/ MRI LI-RADS with either LI-RADS SHF, LI-RADS PFB, or a modified algorithm incorporating the Kupffer-phase findings for PFB [modified PFB]) were evaluated. For the three combination strategies, apart from the CT/MRI LR-5 criteria, HCC was diagnosed if CT/MRI LR-3 or LR-4 observations met the LR-5 criteria using LI-RADS SHF, LI-RADS PFB, or modified PFB. Results: In total, 281 participants (237 males; mean age, 55 ± 11 years) with 306 observations (227 HCCs, 40 non-HCC malignancies, and 39 benign lesions) were included. Using LI-RADS SHF, LI-RADS PFB, and modified PFB, 20, 23, and 31 CT/MRI LR-3/4 observations, respectively, were reclassified as LR-5, and all were pathologically confirmed as HCCs. Compared to CT/MRI LI-RADS alone (74%, 95% confidence interval [CI]: 68%–79%), the three combination strategies combining CT/MRI LI-RADS with either LI-RADS SHF, LI-RADS PFB, or modified PFB increased sensitivity (83% [95% CI: 77%–87%], 84% [95% CI: 79%–89%], 88% [95% CI: 83%–92%], respectively; all P < 0.001), while maintaining the specificity at 92% (95% CI: 84%–97%). Conclusion The combination of CT/MRI LI-RADS with second-line CEUS using SHF or PFB improved the sensitivity of HCC diagnosis without compromising specificity.

Objective:To evaluate the clinical utility of an intelligent endoscope transportation system in the digestive endoscopy center.Methods:A parallel-group controlled trial was conducted at Digestive Endoscopy Center of Qilu Hospital of Shandong University from June 1st to December 31st 2024, comparing robotic intelligent endoscope transport (experimental group) versus manual transport (control group). Performance metrics, including response time, transportation speed, labor efficiency, contamination prevention, closed-loop traceability, and nursing staff satisfaction, were statistically analyzed. Full-time equivalent (FTE) was introduced to quantify the operational efficiency of the experimental group.Results:The study included a total of 60 206 instances of intelligent endoscope transportation and 60 485 instances of manual transportation data. The robotic group demonstrated significantly shorter response times versus manual group for initial dispatch (51.08±14.97 seconds VS 54.44±13.61 seconds, t=35.8, P<0.001) and recovery response time (32.52±11.26 seconds VS 40.20±11.40 seconds, t=103.93, P<0.001). During the 148 days operational period, the success rate was 99.83% (60 104/60 206) and the failure rate was 0.17% (102/60 206) for robotic transports. Primary failure causes were wireless disconnection, pathfinding errors, and mechanical faults, averaging 1.05 malfunctions/month with no adverse events. The success and failure rate was 99.26% (60 043/60 485) and 0.74% (442/60 485) respectively for manual transports. Staff satisfaction was significantly higher for robotic transport in endoscopic transportation (4.65±0.55 scores VS 3.97±0.98 scores, t=96.5, P<0.001) and delivery process (4.71±0.59 scores VS 3.90±1.04 scores, t=210.3, P<0.001). and workload intensity was significantly lower (4.06±0.77 scores VS 4.48±0.63 scores, t=59.9, P=0.025). The system reduced labor requirements by 3.68 FTE, yielding annual savings of ￥657 000. Conclusion:The robotic intelligent endoscope transport system improves work efficiency, reduces nursing labor costs and physical workload, enhances job experience and satisfaction, and enables full-process smart traceability, providing a validated solution for endoscopy center logistics.

Objective:To understand the prevalence of hearing loss among individuals aged 60 and above undergoing physical examinations and to explore the feasibility of using pure tone audiometry (PTA) for hearing screening in the elderly population, as well as to establish screening criteria suitable for our country.Methods:The study was a cross-sectional study, a total of 1 066 elderly individuals (619 males and 447 females; Age range: 60-90 years old, with an average of 66.5 years old) who underwent physical examinations at the Peking Union Medical College Hospital physical examination center from February to December 2023, were screened using PTA and the Chinese version Hearing Handicap Inventory for the Elderly Screening (CHHIE-S). Different screening criteria were applied to calculate the proportion of individuals who did not pass the PTA screening in the elderly population. The consistency between these results and the screening outcomes of the CHHIE-S scale was analyzed to explore reasonable screening standards. We performed statistical analysis using SPSS 27.0.Results:It was found that 18.39% of the elderly population had moderate or severe hearing loss. The positive rate determined by the detection of pure tones at a fixed dB level was significantly higher than that based on the average hearing threshold across 0.5, 1, 2, and 4 kHz frequencies (4-frequency pure-tone average, 4fPTA), and the difference was statistically significant ( χ2=136.56, P<0.001). The criterion of 4fPTA>35 dB HL in the better ear showed the highest consistency with the criterion of CHHIE-S>8, with a Kappa value of 0.554 ( P<0.001), and this criterion resulted in a positive rate of 15.57% (166/1 066). Conclusions:Conducting hearing screening based on PTA among the elderly population undergoing physical examinations is an effective and feasible approach. Given the subjective perceptions of the elderly population being screened, a 4fPTA greater than 35 dB HL in both ears might be a reasonable criterion.

Objective:To investigate the effects of psychosocial factors on early puberty and its sex specific differences.Methods:Bengbu Yuhui Longitudinal Study of Children Development Cohort, consisting of 1 162 students in grades 1-3 (524 girls) and their parents, was established in April 2021 in Bengbu, Anhui Province. The parents were surveyed by questionnaire to collect the information about their children's 56 items of psychosocial factor exposures, including 5 dimensions: major life events, early life adversity, interpersonal/relational conflict, family economic status and daily life troubles. Pubertal growth and physical examinations were conducted by trained professionals at baseline, the 1 st (May 2022), 2 nd (October 2022), 3 rd (May 2023), and 4 th (October 2023) follow-up surveys. In this study, the pubertal development status data were from the 4 th follow-up examination. Fianally, the valid data on pubertal development of 1 105 children were obtained, including the data from 510 girls (46.15%). Multinomial logistic regression model was used to analyze the association between psychosocial factors and early puberty, and the final predictors of early puberty were explored by using four models [least absolute shrinkage and selection operator (LASSO), multiple logistic regression, ridge regression, and Bayesian]. Results:The detection rates of early puberty in boys and girls were 13.60% and 16.30%, respectively. The median of intra-group absolute correlation of psychosocial factor exposure (0.042-0.066) was generally higher than that of inter-group among girls (0.031-0.059), while no similar diference was found among boys. LASSO model showed that moving house, being raised by someone other than parents, sexual abuse, peer conflict, high monthly household income, and high exposure to electronics on school days were predictors of early puberty in girls, while moving house and high monthly household income were the predictors of early puberty in girls in all four models (LASSO, multiple logistic regression, ridge regression, and Bayesian). Among boys, only a transient loss from family was a predictor of early puberty.Conclusion:Early puberty in children can be predicted by psychosocial factors, and there are gender-specific differences.

Objective:To investigate the application of pedicled or perforator flaps transfer in the stage Ⅰ tissue defect repair after vulvar cancer surgery.Methods:From January 2005 to December 2023, 20 patients with vulvar cancer who underwent extensive episiectomy or extended episiectomy±inguinal lymph node resection+vulvar defect flap transfer were collected in Huanxing Cancer Hospital of Chaoyang District and Cancer Hospital and Peking Union Medical College, Chinese Academy of Medical Sciences. The survival status, appearance structure, sexual function satisfaction, tumor recurrence, and survival were analyzed.Results:(1) The median age of the 20 patients was 59 years (ranged: 29-73 years). There were 14 patients with recurrence and 6 patients with initial treatment. Pathological types: 14 cases of squamous cell carcinoma, 4 cases of Paget′s disease, 1 case of malignant melanoma, 1 case of adenoid cystic carcinoma (salivary gland type carcinoma). (2) Among the 20 patients, 6 cases underwent extensive episiotomy and 14 underwent extended episiotomy (1 of them underwent extensive excision of inguinal masses). Simultaneous inguinal lymphadenectomy (or dissection) were performed in 11 cases, including 7 cases of bilateral inguinal lymph node resection (or dissection) and 4 cases of unilateral inguinal lymph node resection (or dissection). Flap source: pedicled flap in 12 cases, perforator flap in 8 cases. All the 20 patients were removed at 10-14 days after operation, and all of them survived with rosy skin color and good elasticity. Seventeen cases of transferred flaps healed at stage Ⅰ, 2 cases healed at about 6 weeks due to incision leakage, and 1 case healed at 6 weeks after incision infection debridement. Six months after the operation, 2 cases felt that the pubic mound was thick and swollen. The other 18 cases showed vulva fullness and elasticity, no displacement of urethral opening, no deviation of urethra during urination, no stenosis of vaginal opening, no vulvar scar pain. In addition to 1 unmarried 29-year-old patient and 6 patients over 65 years old who had no sexual life before and after surgery, the other 13 patients had normal sexual life after surgery. (3) The follow-up period were 6 to 100 months, and 9 cases (45%, 9/20) relapsed during the follow-up period. There were 5 deaths (25%, 5/20), who were due to recurrence of vulvar cancer. The 5-year survival rate of 20 patients was 75%, including 83% in 6 patients with initial treatment and 71% in 14 patients with recurrence and reoperation.Conclusions:The combination of flap transfer for episioplasty with vulvar cancer surgery does not affect the wound healing. Because the external structure of the vulva is repaired, it could effectively improve the local wound healing ability and improve the organ function, and has good clinical application value.

AIM To investigate the protective effect of Sanfeng Tongqiao Dropping Pills against house dust mite(HDM)-induced allergic asthma in mice.METHODS Compared to the intact BALB/c mice in the blank control group,the BALB/c mice randomly assigned into the model group,the dexamethasone group(0.67 mg/kg),and the low-dose,medium-dose,and high-dose Sanfeng Tongqiao Dropping Pills groups(15,30 and 60 mg/kg),were induced into acute allergic asthma models via weekly intraperitoneal sensitization with 0.1 mL HDM solution(0.5 mg/mL)for three weeks followed by three consecutive daily intranasal challenges with 10 μL HDM solution(2.5 mg/mL)starting in the third week.The drug administered continuously 7 days after the last excitation.The mice had their airway reactive Penh value detected,their pulmonary pathological changes observed by HE staining,their blood eosinophils(EOS)counted,their Th2 cytokines in lung tissue and serum IgE levels detected by ELISA,and their number of peripheral blood mononuclear cells(PBMC)and pulmonary Th2 cells detected by flow cytometry.Chronic allergic asthma was induced in grouped BALB/c mice through repeated intranasal challenges with 10 μL HDM solution(2.5 mg/mL)administered five times weekly for five consecutive weeks.Drug treatment continued for 14 days following the final challenge.After the final treatment,the mice had their pulmonary pathological changes observed by HE staining,and their levels of Th2 cytokines in B ALF and lung tissue and serum IgE detected by ELISA.RESULTS Compared to the blank control group,the acute allergic asthma model group exhibited increases in Penh value,EOS count and IgE level in serum,IL-4 and IL-5 levels in lung tissue(P＜0.01);obvious pulmonary inflammatory cells infiltration,and thickened airway wall;and increase in pulmonary number of Th2 cells(P＜0.01).Compared to the model group,the groups intervened with Sanfeng Tongqiao Dropping Pills demonstrated decreased Penh value,serum EOS count,IgE level and IL-5 level in lung tissue(P＜0.05,P＜0.01);reduced pulmonary inflammatory infiltration and alleviated airway wall thickening;and decreased number of pulmonary Th2 cells.Compared to the blank group,the chronic allergic asthma model group showed obvious pulmonary inflammatory infiltration and airway wall thickening;and increased EOS count and IgE level in serum,IL-4 and IL-13 in lung tissue and IL-14 in BALF(P＜0.05,P＜0.01).Compared to the model group,the groups intervened with either medium-dose or high-dose Sanfeng Tongqiao Dropping Pills demonstrated reduced pulmonary inflammatory infiltration;and decreased serum EOS count,IgE level,IL-13 in lung tissue and IL-14 in BALF(P＜0.05,P＜0.01).CONCLUSION Sanfeng Tongqiao Dropping Pills reduce Th2 cells in peripheral blood and lung tissue,suppress type 2 inflammation,and thereby alleviate allergic asthma.

Objective To investigate the effects of kaempferol on the oxidative damage and apoptosis of human lens epithelial cells induced by hydrogen peroxide(H2O2),as well as its regulatory role in the Janus kinase 2/signal transducer and activator of transcription 3(JAK2/STAT3)signaling pathway.Methods Human lens epithelial cells HLE-B3 were cultured in vitro and divided into the blank group(no intervention),the model group(400 pmol?L-1 H2O2),the kaempferol group(400 μmol?L-1 H2O2+40 pmol?L-1 kaempferol),the AG490 group(400 pmol?L-1 H2O2+50 μmol?L-1 JAK2/STAT3 signaling pathway inhibitor AG490),the inhibitor group(400 pmol?L-1 H2O2+40 pmol?L-1 kaempferol+50 μmol?L-1 AG490),and the activator group(400 pmol?L-1 H2O2+40 pmol?L-1 kaempferol+0.5 μmol?L-1 JAK2/STAT3 signaling pathway activator C-A1).After 24 h of intervention,Hoechst 33258 staining was used to determine the ap-optosis rate of these cells.Malondialdehyde(MDA)and superoxide dismutase(SOD)kits were used to detect the levels of MDA and SOD.The protein expression levels of Cysteine aspartic protease 3(Caspase-3),B-cell lymphoma-2(Bcl-2),JAK2,STAT3,p-JAK2,and p-STAT3 were detected by Western blot.Results Compared with the blank group,the apop-tosis rate,the MDA level,and the protein expression levels of Caspase-3,p-JAK2,and p-STAT3 increased(all P＜0.05)in the model group,while the protein expression levels of SOD and Bcl-2 decreased(all P＜0.05).Compared with the model group,the apoptosis rate,the MDA level,and the protein expression levels of Caspase-3,p-JAK2,and p-STAT3 decreased in the kaempferol and AG490 groups(all P＜0.05),while the protein expression levels of SOD and Bcl-2 increased(all P＜0.05).Compared with the kaempferol group,the apoptosis rate,the MDA level,and the protein expression levels of Caspase-3,p-JAK2,and p-STAT3 decreased in the inhibitor group,while the protein expression levels of SOD and Bcl-2 in-creased(all P＜0.05);the changes in the above indicators in the activator group were opposite to those in the inhibitor group(all P＜0.05).Conclusion Kaempferol can protect HLE-B3 cells from H2O2-induced oxidative damage and inhibit their apoptosis by inhibiting JAK2/STAT3 signaling pathway.

Hearing loss is the most prevalent disabling disease. Cochlear implantation（CI） serves as the primary intervention for severe to profound hearing loss. This consensus systematically explores the value of genetic diagnosis in the pre-operative assessment and efficacy prognosis for CI. Drawing upon domestic and international research and clinical experience, it proposes an evidence-based medicine three-tiered prognostic classification system（Favorable, Marginal, Poor）. The consensus focuses on common hereditary non-syndromic hearing loss（such as that caused by mutations in genes like GJB2, SLC26A4, OTOF, LOXHD1） and syndromic hereditary hearing loss（such as Jervell & Lange-Nielsen syndrome and Waardenburg syndrome）, which are closely associated with congenital hearing loss, analyzing the impact of their pathological mechanisms on CI outcomes. The consensus provides recommendations based on multiple round of expert discussion and voting. It emphasizes that genetic diagnosis can optimize patient selection, predict prognosis, guide post-operative rehabilitation, offer stratified management strategies for patients with different genotypes, and advance the application of precision medicine in the field of CI.
