    使用无创临床方法预测肝硬化(LC)患者食管静脉曲张(EV)的存在和严重程度,生物化学,和成像参数。这项研究的目的是调查EV的非侵入性预测因子的准确性,如血小板计数与脾脏直径比(PSR),血小板计数与脾脏体积比(PSVR),脾脏大小(SZ),以及这些标志物的组合在确定肝硬化患者EV的严重程度中。
    我们招募了2018年1月至2019年12月在广西医科大学第一附属医院消化内科住院的82例LC患者。所有患者均行内镜检查,超声,计算机断层扫描,和常规实验室调查。对于这项研究,我们评估并比较了PSR的诊断准确性,PSVR,SZ,和他们的组合。
    对于所有变量,在重度和中度/重度EV的预测中,受试者工作特征(ROC)曲线下面积(AUC)存在显着差异。PSR+PSVR在预测重度和中度/重度EV方面的AUC最高,分别为0.735(95%CI:0.626-0.826)和0.765(95%CI:0.659-0.852)。分别。PSR的AUC(95%CI)差异有统计学意义,PSVR,和PSR+PSVR预测EV的存在。根据整体模型质量图,PSR+PSVR的组合是检测EV存在的最佳指标(AUC,0.696;95%CI:0.584-0.792)。
    在我们的研究中,我们发现,这些无创参数可以预测LC患者EV的严重程度.随着研究的进展,我们预计PSR+PSVR的组合将成为更好的指标。
    UNASSIGNED: The presence and extent of severity of esophageal varices (EV) in patients with liver cirrhosis (LC) are predicted using noninvasive clinical, biochemical, and imaging parameters. The aim of this study was to investigate the accuracy of noninvasive predictors of EV, such as the platelet count-to-spleen diameter ratio (PSR), platelet count-to-spleen volume ratio (PSVR), spleen size (SZ), and a combination of these markers in determining the severity of EV in patients with cirrhosis.
    UNASSIGNED: We recruited 82 inpatients with LC from the Department of Gastroenterology at the First Affiliated Hospital of Guangxi Medical University between January 2018 and December 2019 for this diagnostic investigation. All patients underwent endoscopy, ultrasound, computed tomography, and routine laboratory investigations. For the study, we evaluated and compared the diagnostic accuracy of PSR, PSVR, SZ, and their combinations.
    UNASSIGNED: There were significant differences in the area under the receiver operating characteristic (ROC) curve (AUC) in the prediction of severe and moderate/severe EV for all the variables. PSR+PSVR had the highest AUC at 0.735 (95% CI: 0.626-0.826) and 0.765 (95% CI: 0.659-0.852) for predicting severe and moderate/severe EV, respectively. There were statistically significant differences in the AUCs (95% CI) for PSR, PSVR, and PSR+PSVR in predicting the existence of EV. As per the overall model quality chart, the combination of PSR+PSVR was the best indicator for detecting the presence of EV (AUC, 0.696; 95% CI: 0.584-0.792).
    UNASSIGNED: In our study, we found that these noninvasive parameters could predict the extent of severity of EV in patients with LC. We anticipate the use of a combination of PSR + PSVR to emerge as the superior indicator as studies progress.

    目的:先前有报道称反复暴露于缺氧会增加脾脏的大小和血红蛋白(HGB)水平,而最近有关呼吸暂停对脾脏大小和血液学参数的影响的报道是矛盾的。因此,本研究旨在评估呼吸暂停训练对脾脏大小和血液参数的影响。方法:屏气(BH)组由12名没有BH运动经验的当地学生运动员组成,他们进行了BH慢跑和BH跳绳动态呼吸暂停协议,每周五次,共8周。随着运动员的呼吸暂停耐受性的提高(20至35s),BH事件持续时间逐渐增加。没有BH的对照组(n=10)执行相同的训练任务。用超声系统测量脾脏大小,并对肘静脉血中进行全血细胞分析。结果:BH组脾脏体积从109±13ml增加到136±13ml(p<0.001),大体积血小板从70.50±5.83下降到65.17±5.87(p=0.034),但没有记录到红细胞的变化(p=0.914),HGB(p=0.637),PLT(p=0.346)和WBC(p=0.532)。对照组的脾脏大小或血液学参数没有变化。结论:在这项研究中评估的运动员中,八周的干动力呼吸暂停训练增加了脾脏大小并减少了循环大血小板的数量。然而,运动员的基线RBC计数和HGB水平没有因训练计划而改变.
    Purpose: It has previously been reported that repeated exposure to hypoxia increases spleen size and haemoglobin (HGB) level and recent reports on the effect apnoea has on spleen size and haematological parameters are contradictory. Therefore, this study aims to evaluate the effect apnoea training has on spleen size and haematological parameters. Methods: The breath-holding (BH) group was comprised of 12 local student-athletes with no BH exercise experience who performed BH jogging and BH jumping rope dynamic apnoea protocols, five times weekly for 8 weeks. The BH event duration was progressively increased as the apnoea tolerance of the athletes improved (20 to 35 s). The same training task was performed by the control group (n = 10) without BH. Spleen sizes were measured with an ultrasound system and a complete blood cell analysis was performed on the median cubital venous blood. Results: Spleen volume in the BH group increased from 109 ± 13 ml to 136 ± 13 ml (p < 0.001), and bulky platelets decreased from 70.50 ± 5.83 to 65.17 ± 5.87 (p = 0.034), but no changes were recorded for erythrocytes (p = 0.914), HGB (p = 0.637), PLTs (p = 0.346) and WBC (p = 0.532). No changes were recorded for the control group regarding spleen size or haematological parameters. Conclusion: Eight weeks of dry dynamic apnoea training increased spleen size and decreased the number of circulating bulky platelets in the athletes who were assessed in this study. However, the baseline RBC counts and HGB levels of the athletes were not altered by the training programme.

    OBJECTIVE: To investigate whether and how spleen size measured on magnetic resonance imaging (MRI) could be used to stage liver fibrosis.
    METHODS: Sixteen minipigs were used to prospectively model liver fibrosis staged by biopsy. Abdominal gadolinium-enhanced MRI was performed on the 0, 5th, 9th, 16th, and 21st weekend after beginning of the modeling. Splenic maximal width (W), thickness (T), length (L), and area (S) together with spleen volume (SV) and liver volume (LV) were measured on enhanced MRI and the ratio of SV to LV (SV/LV) was calculated. Spleen multidimensional indexes 1 and 2 were obtained by W × T × L and S × L, respectively. Statistical analyses were performed to determine which parameter could best stage the fibrosis.
    RESULTS: W, T, L, S, SV, index 1 and 2, and SV/LV tended to increase with increasing stages of fibrosis (r = 0.46-0.796, all P < 0.001), and might predict liver fibrosis stage ≥1, ≥2, ≥3, and 4 (area under receiver operating characteristic curve [AUC] = 0.697-1.0, all P < 0.05). Among the parameters, splenic index 1, SV, and SV/LV might be best for predicting stage ≥1 (AUC = 0.941), ≥2 or ≥3 (AUC = 0.875 or 0.978, respectively), and 4 (AUC = 1.0), respectively.
    CONCLUSIONS: Spleen size measured on MRI could be used for staging liver fibrosis.
