Objective:To investigate the attention level of oral medicine residents in standardized training (referred to as residency training) to oral aesthetic information and its influencing factors.Methods:This study was a cross-sectional study, which included 262 residents undergoing standardized training at Hospital of Stomatology, Wuhan University in January 2020. Among them, there were 73 males and 189 females, with an age range of 23-33 (26±2) years. A questionnaire survey method was used, and the questionnaire included the basic characteristics of the subjects (gender, grade, major, identity, and having training experience in prosthodontic base or not) as well as their attention to oral aesthetic information (facial proportions, facial midline, smile line, facial contour, E-line, nasolabial angle, tooth shape and contour, and tooth proportions). Differences in the attention to oral aesthetic information among residents with different basic characteristics were compared, and a multivariable logistic regression was used to identify the influencing factors.Results:Among the 262 oral medicine residents, 256 (97.7%) believed that it was necessary to pay attention to oral aesthetic information. The differences in attention to facial proportions between residents of different genders and between those with and without training experience in the prosthodontic base were statistically significant (both P<0.05). The results of the multivariate logistic regression showed that male residents were less likely to pay attention to facial proportions compared with female residents ( OR=0.45, 95% CI: 0.23-0.88). Compared with residents specializing in orthodontics, non-orthodontic residents were less likely to pay attention to the E-line ( OR=0.14-0.27, 95% CI: 0.04-0.68) and nasolabial angle ( OR=0.14-0.31, 95% CI: 0.04-0.81). Residents who were graduate students with integrated four certificates were more likely to pay attention to the E-line compared with industry-based personnel ( OR=1.88, 95% CI: 1.01-3.49). Residents without training experience in the prosthodontic base were less likely to pay attention to the facial proportion ( OR=0.44, 95% CI: 0.20-0.97) and tooth shape and contour ( OR=0.33, 95% CI: 0.11-0.98) compared with those with such training experience in prosthodontic base. Conclusions:Oral medicine residents have a high level of attention to oral aesthetic information. Gender, major, identity, and having training experience in the prosthodontic base or not are factors that influence their attention to oral aesthetic information.

Objective To investigate the diagnostic efficacy of targeted biopsy(TB)combined with ipsilateral hemiglandular systematic biopsy(SB)of the dominant lesion,so as to explore a novel reduced-core biopsy strategy.Methods A retrospective analysis was conducted on the clinical data of 299 patients treated in our hospital during Sep.1,2022,and Feb.28,2023,who had a Prostate Imaging Reporting and Data System(PI-RADS)score ≥3 and underwent combined TB and SB.The dominant lesion was defined as the lesion with the highest PI-RADS score on multi-parametric magnetic resonance imaging(mpMRI);in cases of identical scores,the largest was designated as the dominant.SB was categorized as ipsilateral(ipsi-SB)or contralateral(contra-SB)to the dominant lesion.The consistency in detecting clinically significant prostate cancer(csPCa)was compared between TB with ipsi-SB(TB+ipsi-SB),TB with contra-SB(TB+contra-SB),and TB with SB(TB+SB).Subgroup analyses were performed based on PI-RADS score,prostate-specific antigen(PSA)level,prostate volume(PV),and mpMRI lesion distribution to evaluate csPCa detection rates across different variables.Results TB+ipsi-SB demonstrated comparable detection rate to TB+SB(46.2％vs.46.8％).The K values for TB+ipsi-SB and TB+contra-SB relative to TB+SB were 0.987(95％CI:0.969-1.000,P＜0.01)and 0.933(95％CI:0.892-0.974,P＜0.01),respectively.Across all subgroups,TB+ipsi-SB showed the highest agreement with TB+SB.Notably,in subgroups with PI-RADS 3 and 5,PSA＞0-20 ng/mL,PV＜25 mL,bilateral or multiple mpMRI lesions,TB+ipsi-SB achieved complete concordance with TB+SB in csPCa detection[K=1.000(95％CI:1.000-1.000),P＜0.01].Conclusion For patients with PI-RADS score ≥3,TB+ipsi-SB exhibits near-perfect consistency with TB+SB in csPCa detection while requiring fewer biopsy cores.TB+ipsi-SB represents a promising refinement of the TB+SB approach.

Objective To investigate the clinical diagnostic value of extra-spindle pole-like protein 1(ESPL1)in the progression of hepatitis B virus(HBV)-related liver fibrosis.Methods A total of 228 patients with HBV infection who were admitted to The First Affiliated Hospital of Guangxi Medical University from June 2017 to August 2023 were enrolled.The transient elastography system FibroScan was used to determine liver stiffness measurement(LSM)for all patients,and according to the LSM value,they were divided into non-liver fibrosis group with 80 patients,mild liver fibrosis group with 83 patients,advanced liver fibrosis group with 30 patients,and liver cirrhosis group with 35 patients.ELISA was used to measure the serum level of ESPL1.The Kruskal-Wallis H test was used for comparison of the serum level of ESPL1 between the four groups;the Spearman correlation analysis was used to investigate the correlation between ESPL1 and LSM;the receiver operating characteristic(ROC)curve was used to analyze the value of serum ESPL1 in predicting the progression of liver fibrosis.Results The liver cirrhosis group had a significantly higher serum level of ESPL1 than the non-liver fibrosis group and the mild liver fibrosis group(both P<0.05),and the advanced liver fibrosis group and the mild liver fibrosis group had a significantly higher serum level of ESPL1 than the non-liver fibrosis group(both P<0.05).The correlation analysis showed that there was a positive correlation between serum ESPL1 and LSM in the patients with HBV infection and varying degrees of liver fibrosis(r=0.515,P<0.001).Serum ESPL1 had an area under the ROC curve(AUC)of 0.809 in predicting liver cirrhosis and an AUC of 0.638 in predicting advanced liver fibrosis,with a sensitivity of 87.5%and 100%,respectively,and a specificity of 59.7%and 31.3%,respectively.Conclusion There is a certain correlation between serum ESPL1 and HBV-related liver fibrosis,and higher serum ESPL1 may indicate a higher degree of liver fibrosis.Serum ESPL1 is expected to become one of the serum markers for assisting in the diagnosis of liver cirrhosis and an important clinical method for dynamically monitoring the progression of liver fibrosis in patients with HBV infection.

BACKGROUND: LY01005 (Goserelin acetate sustained-release microsphere injection) is a modified gonadotropin-releasing hormone (GnRH) agonist injected monthly. This phase III trial study aimed to evaluated the efficacy and safety of LY01005 in Chinese patients with prostate cancer. METHODS: We conducted a randomized controlled, open-label, non-inferiority trial across 49 sites in China. This study included 290 patients with prostate cancer who received either LY01005 or goserelin implants every 28 days for three injections. The primary efficacy endpoints were the percentage of patients with testosterone suppression ≤50 ng/dL at day 29 and the cumulative probability of testosterone ≤50 ng/dL from day 29 to 85. Non-inferiority was prespecified at a margin of -10%. Secondary endpoints included significant castration (≤20 ng/dL), testosterone surge within 72 h following repeated dosing, and changes in luteinizing hormone, follicle-stimulating hormone, and prostate specific antigen levels. RESULTS: On day 29, in the LY01005 and goserelin implant groups, testosterone concentrations fell below medical-castration levels in 99.3% (142/143) and 100% (140/140) of patients, respectively, with a difference of -0.7% (95% confidence interval [CI], -3.9% to 2.0%) between the two groups. The cumulative probabilities of maintaining castration from days 29 to 85 were 99.3% and 97.8%, respectively, with a between-group difference of 1.5% (95% CI, -1.3% to 4.4%). Both results met the criterion for non-inferiority. Secondary endpoints were similar between groups. Both treatments were well-tolerated. LY01005 was associated with fewer injection-site reactions than the goserelin implant (0% vs . 1.4% [2/145]). CONCLUSION: LY01005 is as effective as goserelin implants in reducing testosterone to castration levels, with a similar safety profile. TRIAL REGISTRATION ClinicalTrials.gov, NCT04563936.

Objective: To report our initial experience with extraperitoneal approach Robotic-Assisted Urethra-sparing simple prostatectomy(US-RASP)on large-gland (>100 ml) benign prostatic hyperplasia(BPH). Methods: From August 2015 to April 2018, 32 patients with large volume prostate underwent US-RASP performed by single surgical team were retrospectively reviewed. The patient's median age was 73 (range 59-80) years, and median BMI was 24.9 (19.3-34.8 ) kg/m^2, The estimated prostate volume(V), postvoid residual volume(PV) by transrectal ultrasonography and PSA were 152.0(119.0-223.1)ml, 145(0-280)ml and 13.7(5.2-27.3)ng/ml, respectively. Four of 32 patients underwent preoperative urinary catheterization. The perioperative functional parameters including international prostate symptom score (IPSS) questionnaire, maximum flow rate (Q_max), maximum voided volume(V_max), quality of life questionnaires (QOL) and International Index of erectile function-erectile function (IIEF-EF) were 27(23-33), 5.9 (2.5-7.8) ml/s, 110 (80-210)ml, 5(3-6), and 27(26-29), respectively. Functional parameters including IPSS, QOL, Qmax, Vmax, PV and IIEF-EF were compared and analyzed at 3 and 12 months postoperatively during the following-up. Results: The US-RASP was completed in all 32 patients and no open conversion. Median operation time was 180 (115-240) min, the estimated blood loss was 300(range 100 to 400)ml, Hemoglobin loss was 17(5-38)g/L. The median Foley catheterization time was 7 (5-12) days and drainage was removed after a median of 5 (4-7) days with median hospital stay of 8(6-14)days. Median specimen weight on pathological examination was 107.7 (79.8-147.4)g with median of 64.2% (49.4%-86.2%) resection ratio. At 3-mo follow-up, median IPSS score, Q_max, V_max, PV and QOL were 6(4-18), 17.3 (13.8-21.1)ml/s, 167(140-310)ml, 50(0-61)ml, 1(0-3) , respectively. At 12-mo follow-up, median IPSS score, Q_max, V_max, PV and QOL were 4(1-9), 20.1 (17.9-24.1)ml/s, 205(176-305)ml, 24(0-35)ml and 1(0-2) , respectively. All patients showed great improvement of IPSS, Q_max, V_max, PV and QOL after median 17 (12-44) months follow-up compared with preoperative parameters (P<0.05). Erectile function was not impaired in 17 patients who have normal erectile function pre-operatively and 14 cases (82.4%) preserved satisfactory anterograde ejaculation. No significant complication occurred during the procedure. No patient developed permanent urinary incontinence. Conclusions US-RASP is a safe and effective treatment option for selected patients with large-gland obstructive BPH(>100 ml). Our data showed significant improvement in voiding function and maintaining satisfactory anterograde ejaculation following urethral-sparing technique. It may be a new alternative method in the future for large-volume symptomatic BPH.
