    本研究调查了节段准确性和核位置对英语作为国际语言(EIL)的可理解性的影响,目的是告知语音规范和教学模式。在阅读任务期间,收集了59个EIL说话者的语音样本,涉及阅读三个不同版本的演讲,每个版本持续大约30到40秒。为了直接比较核应力放置对可理解性的影响,基于这些样本,创建了两个版本的刺激,每个人的不同之处仅在于核应力的位置-正确或不正确。安置的正确性由七个以英语为母语的人确定。八个以英语为母语的人,19-24岁,8个EIL使用者,20-24岁,具有中高级到高级水平,对两个版本的演讲的可理解性进行了评级。结果表明,尽管正确的细胞核放置可以增强英语母语听众的可理解性,它对EIL听众影响不大。EIL语音的分段准确性对本地和EIL听众的可理解性的影响远大于核放置,这表明英语教学应侧重于尽量减少分段错误,以提高EIL使用者的可理解性,尽管正确的核放置有好处。
    This study investigates the impact of segmental accuracy and nucleus placement on the comprehensibility of English as an International Language (EIL), with the aim of informing phonological norms and teaching models. Speech samples from 59 EIL speakers with varying levels of segmental accuracy were collected during a reading task, involving reading a passage in three different versions of speech, each version lasting approximately 30 to 40 s. To directly compare the impact of nuclear stress placement on comprehensibility, based on these samples, two versions of stimuli were created, each differing only in their placement of nuclear stress - either correct or incorrect. The correctness of placements was determined by seven native speakers of English. Eight native English speakers, aged 19-24, and eight EIL speakers, aged 20-24 with an upper-intermediate to advanced proficiency level, rated the comprehensibility of the two versions of speech. Results suggest that while correct nucleus placement enhances comprehensibility for native English listeners, it has little influence on EIL listeners. Segmental accuracy in EIL speech impacts comprehensibility substantially more than nucleus placement on both native and EIL listeners, indicating that English language teaching should focus on minimizing segmental errors to improve comprehensibility for EIL speakers, despite the benefits of correct nucleus placement.

    我们检查了从土城子遗址出土的一个人的遗骸,据信他来自中国战国时期。遗骸表现为股骨节段性骨折。我们的目的是推断骨折的原因,医疗干预,愈合过程,和骨折愈合后的运动行为,使用几种技术,包括宏观观察,计算机断层扫描(CT),有限元分析。根据长骨的形态,似乎这个人是男性。骨折导致股骨近端内收角度为5.47°,前屈角度为21.34°,而股骨颈前倾角已被10.74°的后倾角所取代。此外,股骨远端形成144.60°的异常前凸角。CT显示成熟的愈伤组织形成和可见的小梁束。有限元分析表明,站立时股骨最大vonMises应力为17.44MPa,行走时最大vonMises应力为96.46MPa。我们建议战国时期的医生对大腿解剖有很好的了解,使他们能够进行骨折复位和固定。合理的医疗干预有利于骨折愈合和负荷恢复。满意的骨折愈合确保个体在康复后能够进行正常的站立和行走活动。
    We examined the remains of an individual who was unearthed from the Tuchengzi site and was believed to be from the Warring States period in China. The remains exhibited segmental femoral fracture. We aimed to deduce the cause of fracture, medical interventions, healing process, and motion behavior after fracture healing using several techniques, including macroscopic observation, computed tomography (CT), and finite element analysis. Based on the morphology of the long bones, it appeared that the individual was male. The fractures resulted in an adduction angle of 5.47° and an anterior flexion angle of 21.34° in the proximal femur, while the femoral neck anteversion angle had been replaced by a retroversion angle of 10.74°. Additionally, the distal femur formed an abnormal anterior convex angle of 144.60°. CT revealed mature callus formation and visible trabecular bundles. The finite element analysis indicated that the maximum von Mises stress in the femur was 17.44 MPa during standing and 96.46 MPa during walking. We suggest that medical practitioners in the Warring States period possessed a good knowledge of thigh anatomy, enabling them to perform fracture reduction and fixation. Reasonable medical intervention facilitated fracture healing and load recovery. Satisfactory fracture healing ensured that the individual could engage in normal standing and walking activities after rehabilitation.

    描述巩膜屈曲(SB)手术治疗早产儿4A期视网膜病变(ROP)的长期效果。
    对2010年10月至2021年10月期间诊断为4A期ROP的患者进行回顾性图表回顾。基本数据来自患者图表,包括性别,出生体重,出生时的胎龄,疾病阶段,+疾病的存在,术前治疗[激光光凝,玻璃体内抗血管内皮生长因子(VEGF)药物治疗,或两者的组合]和并发症(玻璃体出血),手术后的月经年龄,术中联合治疗,和随访的总长度。术后视网膜附着状态,术后并发症(青光眼,白内障),后续视网膜手术的日期和类型(如果进行),术后1年评估屈光状态。第一次手术后的随访时间超过1年。
    48例患者的6-2只眼符合本研究的纳入标准。初次重贴率为93.5%(58/62眼),在随访结束时进行两次手术后,最终的再附着率为100%。白内障的发病率为3.2%(2/62),没有眼睛,随后需要进行晶状体切除术。在随访期间,没有患者出现青光眼。术后1年,患者的平均等效球面屈光度值为-3.00±2.51D(-7.60D至2.75D)。
    SB,尤其是节段屈曲,减少近视,不需要脱扣,有可能在4A期ROP的治疗中提供显著的积极影响。
    UNASSIGNED: To describe the long-term effect of scleral buckling (SB) surgery for stage 4A retinopathy of prematurity (ROP).
    UNASSIGNED: A retrospective chart review was conducted for patients with a diagnosis of stage 4A ROP who underwent SB between October 2010 and October 2021. Basic data were collected from patient charts, including gender, birth weight, gestational age at birth, disease stage, presence of plus disease, preoperative treatment [laser photocoagulation, intravitreal anti-vascular endothelial growth factor (VEGF) agent therapy, or a combination of both] and complications (vitreous hemorrhages), postmenstrual age at surgery, intraoperative combined treatment, and total length of follow-up. Retinal attachment status after surgery, postoperative complications (glaucoma, cataract), date and type of subsequent retinal surgeries (if performed), and refractive status 1 year after surgery were evaluated. The follow-up time after the first procedure was over 1 year.
    UNASSIGNED: Six-two eyes from forty-eight patients met the inclusion criteria for this study. The initial reattachment rate was 93.5% (58/62 eyes), and the final reattachment rate was 100% after two procedures at the end of follow-up. The incidence of cataracts was 3.2% (2/62), with no eye subsequently needing lensectomy surgery. None of the patients developed glaucoma during the follow-up time. The average spherical equivalent refraction value for patients was -3.00 ± 2.51 D (-7.60 D to +2.75 D) 1 year after surgery.
    UNASSIGNED: SB, especially segmental buckling, which induces less myopia and does not require buckle removal, has the potential to provide a significant positive impact in the treatment of stage 4A ROP.

    未经授权:保乳手术(BCS)是早期乳腺癌的首选方法,术前准确预测BCS的可行性,可以制定手术方案,减少对患者意志的违背。本研究旨在探索与失败的BCS相关的术前磁共振成像(MRI)特征,并构建基于MRI的模型来预测BCS。
    UNASSIGNED:这项回顾性研究包括2015年3月至2016年7月计划接受BCS的患者,术前做过核磁共振检查,并有至少2年的随访。根据年龄,共确定30例BCS失败的患者,并与90例BCS成功的患者进行匹配(比例为1:3),新辅助治疗,和激素受体表达。将患者分为训练组进行模型构建和试验组进行模型验证。MRI特征,包括肿瘤的部位,病变类型,病变和乳房体积,比较失败和成功BCS组。使用与来自训练组的失败的BCS相关的独立因素构建了用于预测失败的BCS的多变量逻辑模型,并在测试组中进行了评估。使用接收器工作特性(ROC)曲线评估模型的性能。
    未经证实:该队列的平均年龄为45.7±10.3岁。非肿块性病变和多病灶明显增多,病变体积越大,与BCS成功组相比,BCS失败组的病灶比例和乳腺体积。病变比例、乳腺体积和多病灶是BCS失败的独立因素。比值比为1.044(95%CI:1.016-1.074)和11.161(95%CI:1.739-71.652),分别。建立了基于MRI的BCS失效预测模型,训练组和试验组的ROC曲线下面积分别为0.902和0.821.
    UNASSIGNED:该模型可能有助于临床医生术前预测失败的BCS并制定准确的手术策略。
    UNASSIGNED: Breast-conserving surgery (BCS) is the preferred method for early breast cancer, and the accurate preoperative prediction of the feasibility of BCS can formulate the surgical plan and reduce the violation of the patient\'s will. The present study proposed to explore the preoperative magnetic resonance imaging (MRI) features associated with failed BCS and constructed an MRI-based model to predict BCS.
    UNASSIGNED: This retrospective study included patients between March 2015 and July 2016, who planned to undergo BCS, had preoperative MRI examination, and had at least 2 years of follow-up. A total of 30 patients with failed BCS were identified and matched with 90 patients with successful BCS (ratio 1:3) according to age, neoadjuvant therapy, and hormone receptor expression. The patients were divided into the training group for model construction and the testing group for model validation. The MRI features, including the site of the tumor, the lesion type, and the lesion and breast volume, were compared between failure and successful BCS groups. A multivariate logistic model for predicting failed BCS was constructed using independent factors associated with failed BCS from the training group and was evaluated in the testing group. The performance of the model was evaluated using the receiver operating characteristic (ROC) curve.
    UNASSIGNED: The mean age of the cohort was 45.7±10.3 years. A significantly more non-mass lesion and multifocality, the larger volume of lesion, and the ratio of lesion and breast volume were observed in failed BCS group compared to the successful BCS group. The ratio of lesion and breast volume and multifocality were independent factors associated with failed BCS, odds ratios were 1.044 (95% CI: 1.016-1.074) and 11.161 (95% CI: 1.739-71.652), respectively. An MRI-based model for predicting failed BCS was established, the area under the ROC curves in the training and testing group were 0.902 and 0.821, respectively.
    UNASSIGNED: This model might help clinicians predict failed BCS preoperatively and make an accurate surgical strategy.

    Considerable controversies exist regarding whether elderly patients with early-stage breast cancer receiving breast-conserving surgery (BCS) should forgo radiotherapy. We utilized the National Cancer Database to analyze data of 115 516 women aged ≥70 years, treated with BCS for T1-2N0-1M0 breast cancer between 2004 and 2014. Multivariable Cox proportional hazards model was used to estimate hazard ratios (HR) and 95% confidence intervals (CI) for mortality 3, 5 and 10 years after 90 days of BCS associated with radiotherapy. Patients who received no radiotherapy had a higher mortality rate than those who received radiotherapy (5-year survival rate: 71.2% vs 83.8%), with multivariable-adjusted HRs of 1.65 (95% CI: 1.57-1.72) for 3-year mortality, 1.53 (1.47-1.58) for 5-year mortality and 1.43 (1.39-1.48) for 10-year mortality. The association held even for patients ≥90 years. This association was observed in all strata by reasons for radiotherapy omission, receipt of endocrine therapy or chemotherapy, calendar period and other clinical characteristics, with 40% to 65% increased 5-year mortality for patients without radiotherapy. This positive association persisted when analyses were restricted to patients with T1N0 and estrogen-receptor-positive disease who had received endocrine therapy (5-year mortality: HR 1.47 [1.39-1.57]) and in propensity score weighted analyses. Our study shows, in routine practice, elderly patients who received no post-BCS radiotherapy had higher total mortality than those who received radiotherapy. These findings suggest that the current recommendation of omission of post-BCS radiotherapy for elderly women with early-stage breast cancer may need to be reconsidered, particularly for those without contraindication.

    Clinical practice of retrieval of segmental (station 13) and subsegmental (station 14) lymph nodes for pathologic examination varies during lung cancer surgery. This study aimed to evaluate whether omitting retrieval of nodes from stations 13 and 14 could affect outcome evaluation for patients with pN0 non-small-cell lung cancer (NSCLC).
    This retrospective study analyzed 442 patients with NSCLC who were treated with both R0 resection and systematic mediastinal lymphadenectomy with pathologically confirmed stage pN0 NSCLC. The study group included patients in whom N1 nodes including stations 10 to 14 were investigated, and the control group included patients in whom stations 10 to 12 only were investigated. Clinical and pathologic parameters of the groups were balanced by propensity score matching, and oncologic outcomes were assessed by the log-rank test.
    A total of 435 cases were included in the final analysis (170 in the study group and 265 in the control group). In the study group, a mean ± SD of 5.0 ± 3.0 nodes per case were collected from nodes 13 and 14. After propensity score matching, 143 cases were included in each group. Overall and disease-free survival improved in the study group compared to the control group (P = .027 and P = .021, respectively). T staging and intrapulmonary node collection were prognostic factors for pN0 cases.
    Inferior oncologic outcomes of pN0 cases without intrapulmonary node retrieval suggest that the procedure of intrapulmonary lymph node retrieval may play a role in outcome evaluation for pN0 NSCLC patients.

    The incidence of segmental testicular infarction is extremely low. The condition usually presents with acute scrotal pain and may be confused clinically and radiologically with a testicular tumor or torsion. To the best of our knowledge, only a few cases have been reported in the English literature. In this study, we present a case of segmental testis infarction in a 23-year-old male with an acute onset of testicular pain. The diagnosis of testicular infarction was considered following sonography examination. Hemorrhagic infarction of the testis was confirmed by surgical exploration and pathological examination. Partial orchiectomy was performed. Although it is uncommon, segmental testicular infarction should be taken into consideration when acute scrotal pain is encountered, since the therapeutic strategy could be conservative.

    Using a multiple-deviant oddball paradigm, this study examined second graders\' brain responses to Cantonese speech. We aimed to address the question of whether a change in a consonant or lexical tone could be automatically detected by children. We measured auditory mismatch responses to place of articulation and voice onset time (VOT), reflecting segmental perception, as well as Cantonese lexical tones including level tone and contour tone, reflecting suprasegmental perception. The data showed that robust mismatch negativities (MMNs) were elicited by all deviants in the time window of 300-500 ms in second graders. Moreover, relative to the standard stimuli, the VOT deviant elicited a robust positive mismatch response, and the level tone deviant elicited a significant MMN in the time window of 150-300 ms. The findings suggest that Hong Kong second graders were sensitive to neural discriminations of speech sounds both at the segmental and suprasegmental levels.
