    作为胃肠胰腺神经内分泌肿瘤(GEPNET)的新型生物标志物的需求,我们旨在验证NETest在日本患者中的临床价值.在2021年至2023年之间,收集了GEPNET患者的血液和临床数据。在35名患者中(中位年龄:59[49-66]岁),27例起源于胰腺,8例起源于胃肠道。在送到实验室的69个样本中,56(81.2%)接受了NETest。诊断灵敏度为97.1%。在3例接受R0切除和4例接受肽受体放射性核素治疗的患者中,NETest评分的变化与疾病进展密切相关。NETest在日本人群中表现出很高的诊断功效和准确的治疗监测能力。
    As novel biomarkers for gastroenteropancreatic neuroendocrine tumors (GEPNET) are in demand, we aimed to validate the clinical value of the NETest in Japanese patients. Between 2021 and 2023, blood and clinical data were collected from patients with GEPNET. Among 35 patients (median age: 59 [49-66] years), 27 cases originated from the pancreas and eight from the gastrointestinal tract. Of 69 samples sent to the laboratory, 56 (81.2%) underwent NETest. The diagnostic sensitivity was 97.1%. Among three patients who underwent R0 resection and four treated with peptide receptor radionuclide therapy, the changes in NETest scores closely correlated with disease progression. The NETest demonstrated high diagnostic efficacy and accurate therapeutic monitoring capabilities in a Japanese population.

    目的:分析地佐辛联合心理护理在术后疼痛管理中的应用。
    方法:这是一项回顾性研究。选取2020年1月至2022年1月在遵义市第一人民医院行微血管减压术(MVD)的186例HFS患者作为研究对象。根据不同的治疗干预措施将患者分为两组。对照组(93例)给予常规围手术期护理,无超前镇痛,观察组93例,在对照组的基础上给予超前镇痛和心理护理。
    结果:在喉罩摘除后30分钟(T3),对照组与观察组Ramsay镇静量表评分比较,差异无统计学意义(P>0.05)。观察组即刻摘除面罩(T2)时的RSS评分和T3时的VAS评分明显低于对照组(P<0.05)。干预之后,观察组SAS、SDS评分明显低于对照组(P<0.05)。基线(T0)和拔除前5分钟(T1)两组间平均动脉压(MAP)和心率(HR)值差异无统计学意义(P>0.05)。然而,在T2和T3时,观察组的MAP和HR值明显低于对照组(P<0.05)。两组各时间点脉搏血氧饱和度(SpO2)值差异均无统计学意义(P>0.05)。
    结论:与标准围手术期护理相比,地佐辛联合超前镇痛及心理护理可有效减轻术后苏醒期疼痛,降低立即拔管相关躁动的风险,术后维持血流动力学稳定。
    UNASSIGNED: To analyze the application of Dezocine combined with psychological care in the postoperative pain management.
    UNASSIGNED: This is a retrospective study. A total of 186 HFS patients who underwent Microvascular Decompression (MVD) at First People\'s Hospital of Zunyi between January 2020 and January 2022 were selected as the study subjects. Patients were divided into two groups based on different treatment interventions. The control group (n = 93) received routine perioperative care without preemptive analgesia, while the observation group (n = 93) received preemptive analgesia and combined psychological care on the basis of the control group\'s intervention.
    UNASSIGNED: At 30 min post-laryngeal mask removal (T3), no significant difference in Ramsay Sedation Scale scores existed between control and observation groups (p > 0.05). The observation group showed significantly lower RSS scores at immediate mask removal (T2) and VAS scores at T3 compared to controls (p < 0.05). Following intervention, the observation group had notably lower SAS and SDS scores than controls (p < 0.05). Baseline (T0) and 5 min pre-removal (T1) exhibited no significant differences in mean arterial pressure (MAP) and heart rate (HR) values between groups (p > 0.05). However, at T2 and T3, the observation group displayed significantly lower MAP and HR values than controls (p < 0.05). No significant differences in pulse oxygen saturation (SpO2) values existed between groups at any time point (p > 0.05).
    UNASSIGNED: Compared to standard perioperative care alone, Dezocine combined with preemptive analgesia and psychological care effectively reduces postoperative pain during the awakening period, lowers the risk of immediate extubation-related agitation, and maintains stable hemodynamics in the postoperative period.

    探讨高频超声联合超声在新生儿食管闭锁(EA)诊断中的应用价值。
    回顾性选择2019年8月至2022年4月在我院接受治愈的70例疑似EA新生儿作为研究对象,分析其术前食管高频超声和超声水文学数据。高频超声的诊断价值,以术中发现为金标准,分析了新生儿EA的超声水成像和联合检测。
    (1)在70名疑似EA的儿童中,62例阳性,8例阴性;单纯超声水文学检查阳性59例,阴性11例;单纯高频超声检查阳性61例,阴性9例;联合检测阳性62例,阴性8例。(2)联合检测的准确率为97.14%,与高频超声92.86%和超声水文学84.29%有显著差异(P<0.05)。(3)超声水文学的诊断AUC,高频超声,联合检测EA分别为0.6125、0.6500、0.6563(P<0.05)。(4)术前高频超声检查距离无明显变化,超声水文学,术中测量IIIA和IIIBEA食管远端和近端盲端(P>0.05)。
    高频超声和超淡水注射血管造影在新生儿EA的诊断中具有良好的应用价值。在III型EA手术之前和期间以及在超淡水注射血管造影术中,食管远端和近端盲端之间的距离没有显着差异。然而,考虑到食管造影引起的辐射和中毒的风险,建议首先选择高频超声进行诊断,如有必要,食管造影可用于联合诊断。
    UNASSIGNED: To explore the application value of high-frequency ultrasound combined with ultrasonography in the diagnosis of neonatal esophageal atresia (EA).
    UNASSIGNED: Seventy neonates with suspected EA who received healing in our hospital from August 2019 to April 2022 were retrospectively selected as the study subjects and their preoperative esophageal high-frequency ultrasound and ultrasound hydrography data were analysed. The diagnostic value of high-frequency ultrasound, ultrasound hydrography and combined detection in neonatal EA was analysed using intraoperative findings as the gold standard.
    UNASSIGNED: (1) Among the 70 children with suspected EA, 62 were confirmed to be positive and 8 were negative; 59 were positive and 11 were negative by ultrasound hydrography alone; 61 were positive and 9 were negative by high-frequency ultrasound alone; 62 were positive and 8 were negative by combined detection.(2) The accuracy of combined detection was 97.14%, which was notably different from 92.86% by high-frequency ultrasound and 84.29% by ultrasound hydrography (P < 0.05).(3) The diagnostic AUC of ultrasound hydrography, high-frequency ultrasound, and combined detection for EA was 0.6125, 0.6500, and 0.6563, respectively (P < 0.05).(4) There was no significant variation in the distance between preoperative high-frequency ultrasound, ultrasound hydrography, and intraoperative measurements of distal and proximal blind ends of type IIIA and IIIB EA esophagus (P > 0.05).
    UNASSIGNED: High frequency ultrasound and super fresh water injection angiography have good application value in the diagnosis of neonatal EA. There is no significant difference between the distance between the distal and proximal blind ends of the esophagus before and during the operation of type III EA and that during the operation of super fresh water injection angiography. However, in consideration of the risk of radiation and poisoning caused by esophagography, it is recommended that high-frequency ultrasound be selected first for diagnosis and if necessary, esophagography be supplemented for joint diagnosis.

    本研究旨在探讨多参数超声评估对脓毒症并发急性肾损伤(AKI)的诊断价值。
    根据AKI的存在,将患者分为AKI组(n=50)和非损伤组(n=50)。收集临床特征,比较两组患者的肾功能指标,包括24小时尿量,血清肌酐,尿素,血清胱抑素C(CysC),肾实质厚度(RPT),肾动脉阻力指数(RI),和多参数超声评分(MPUS)。此外,采用Logistic回归分析确定脓毒症并发AKI的影响因素。使用受试者工作特征(ROC)曲线评估预测值。
    在AKI组中,肌酐,CysC,尿素,MPUS得分,RPT,RI值明显更高,24h尿量低于无损伤组(p<0.01)。此外,多因素logistic分析显示CysC和RI值升高是独立危险因素,而高24小时尿量和低MPUS是脓毒症诱导的AKI的独立保护因素。ROC曲线显示RI(AUC=0.906)比24小时尿量(AUC=0.797)更有效,CysC(AUC=0.730),和MPUS(AUC=0.794)在鉴定脓毒症诱导的AKI中。
    高RI值增加脓毒症诱导的AKI的风险,而低MPUS可能会降低它。RI对脓毒症并发AKI有较高的诊断价值。
    UNASSIGNED: This study aimed to discuss the diagnostic value of multi-parameter ultrasound evaluation in sepsis complicated with acute kidney injury (AKI).
    UNASSIGNED: Patients were divided into an AKI group (n = 50) and a non-injury group (n = 50) based on the presence of AKI. The clinical characteristics were collected, and renal function parameters between the two groups were compared, including 24-h urine volume, serum creatinine, urea, serum cystatin C (CysC), renal parenchymal thickness (RPT), renal artery resistance index (RI), and multi-parameter ultrasound scoring (MPUS). Additionally, logistic regression analysis was conducted to determine the influencing factors of sepsis complicated with AKI. The prediction value was evaluated using a receiver operating characteristic (ROC) curve.
    UNASSIGNED: In the AKI group, creatinine, CysC, urea, MPUS score, RPT, and RI values were significantly higher, while the 24-h urine volume was lower than those in the non-injury group (p < 0.01). Moreover, multivariate logistic analysis indicated that high CysC and RI values were independent risk factors, whereas high 24-h urine volume and low MPUS were independent protective factors for sepsis-induced AKI. The ROC curve demonstrated that RI (AUC = 0.906) was more effective than 24-h urine volume (AUC = 0.797), CysC (AUC = 0.730), and MPUS (AUC = 0.794) in identifying sepsis-induced AKI.
    UNASSIGNED: High RI values increase the risk of sepsis-induced AKI, whereas low MPUS may reduce it. RI showed high diagnosis values for sepsis complicated with AKI.

    结论:经皮穿刺置管引流术治疗SAP并发腹腔积液在发病2d内最有效。
    BACKGROUND: Non-surgical methods such as percutaneous drainage are crucial for the treatment of patients with severe acute pancreatitis (SAP). However, there is still an ongoing debate regarding the optimal timing for abdominal paracentesis catheter placement and drainage.
    OBJECTIVE: To explore the influence of different timing for abdominal paracentesis catheter placement and drainage in SAP complicated by intra-abdominal fluid accumulation.
    METHODS: Using a retrospective approach, 184 cases of SAP complicated by intra-abdominal fluid accumulation were enrolled and categorized into three groups based on the timing of catheter placement: group A (catheter placement within 2 d of symptom onset, n = 89), group B (catheter placement between days 3 and 5 after symptom onset, n = 55), and group C (catheter placement between days 6 and 7 after symptom onset, n = 40). The differences in progression rate, mortality rate, and the number of cases with organ dysfunction were compared among the three groups.
    RESULTS: The progression rate of group A was significantly lower than those in groups B and groups C (2.25% vs 21.82% and 32.50%, P < 0.05). Further, the proportion of patients with at least one organ dysfunction in group A was significantly lower than those in groups B and groups C (41.57% vs 70.91% and 75.00%, P < 0.05). The mortality rates in group A, group B, and group C were similar (P > 0.05). At postoperative day 3, the levels of C-reactive protein (55.41 ± 19.32 mg/L vs 82.25 ± 20.41 mg/L and 88.65 ± 19.14 mg/L, P < 0.05), procalcitonin (1.36 ± 0.51 ng/mL vs 3.20 ± 0.97 ng/mL and 3.41 ± 0.98 ng/mL, P < 0.05), tumor necrosis factor-alpha (15.12 ± 6.63 pg/L vs 22.26 ± 9.96 pg/L and 23.39 ± 9.12 pg/L, P < 0.05), interleukin-6 (332.14 ± 90.16 ng/L vs 412.20 ± 88.50 ng/L and 420.08 ± 87.65ng/L, P < 0.05), interleukin-8 (415.54 ± 68.43 ng/L vs 505.80 ± 66.90 ng/L and 510.43 ± 68.23ng/L, P < 0.05) and serum amyloid A (270.06 ± 78.49 mg/L vs 344.41 ± 81.96 mg/L and 350.60 ± 80.42 mg/L, P < 0.05) were significantly lower in group A compared to those in groups B and group C. The length of hospital stay in group A was significantly lower than those in groups B and group C (24.50 ± 4.16 d vs 35.54 ± 6.62 d and 38.89 ± 7.10 d, P < 0.05). The hospitalization expenses in group A were also significantly lower than those in groups B and groups C [2.70 (1.20, 3.55) ten-thousand-yuan vs 5.50 (2.98, 7.12) ten-thousand-yuan and 6.00 (3.10, 8.05) ten-thousand-yuan, P < 0.05). The incidence of complications in group A was markedly lower than that in group C (5.62% vs 25.00%, P < 0.05), and similar to group B (P > 0.05).
    CONCLUSIONS: Percutaneous catheter drainage for the treatment of SAP complicated by intra-abdominal fluid accumulation is most effective when performed within 2 d of onset.

    回顾性分析2013年1月至2023年4月入院并经病理证实的20例ICTH患者和45例FAVA患者的临床及超声影像学资料。对比分析两组患者的临床及超声表现。进行了逐步回归分析,并使用选择的最终变量构建了联合诊断方程。接收器工作特性(ROC)曲线和指标,包括敏感性和特异性,用于评价联合诊断模型的疗效。
    ICTH和FAVA两组患者的年龄差异有统计学意义(P<0.05),\'病变大小\',筋膜尾部标志,\'病变周围存在类似脂肪组织的hyperecho\',“血流”和“病变内存在直毛细血管”。最后,选择变量\'筋膜尾征\'和\'病变内是否存在直毛细血管\'来构建模型。构建的联合诊断模型的敏感性值为70.0%(95%CI:59.00-81.00),特异性值为98.0%(95%CI:94.70-0.00),ROC曲线值为0.908,表明联合诊断方法的高疗效。
    超声检查可用于区分ICTH和FAVA,联合诊断方法可以进一步提高该技术的诊断效能。
    UNASSIGNED: To investigate the value of ultrasonography as a diagnostic aid in differentiating intramuscular capillary-type hemangioma (ICTH) from fibro-adipose vascular anomaly (FAVA).
    UNASSIGNED: A retrospective analysis was conducted of the clinical and ultrasound imaging data of 20 patients with ICTH and 45 patients with FAVA who were admitted to and pathologically confirmed in hospital between January 2013 and April 2023. The clinical and ultrasonographic appearances of the lesions in the two groups were compared and analyzed. A stepwise regression analysis was performed, and a joint diagnostic equation was constructed using the final variables selected. The receiver operating characteristic (ROC) curve and indicators, including sensitivity and specificity, were used to evaluate the efficacy of the joint diagnostic model.
    UNASSIGNED: The two groups of patients suffering from ICTH and FAVA presented a statistically significant difference (P< 0.05) in terms of \'age\', \'lesion size\', \'fascial tail sign\', \'presence of a fatty-tissue-like hyperecho around the lesion\', \'blood flow\' and \'presence of straight blood capillaries within the lesion\'. Finally, the variables \'fascial tail sign\' and \'presence of straight blood capillaries within the lesion\' were selected to construct the model. The constructed joint diagnostic model had a sensitivity value of 70.0% (95% CI: 59.00-81.00), a specificity value of 98.0% (95% CI: 94.70-100.00) and a ROC curve value of 0.908, indicating the high efficacy of the combined diagnosis method.
    UNASSIGNED: Ultrasonography can be utilized to differentiate ICTH from FAVA, and the combined diagnosis method can further improve the technique\'s diagnostic efficacy.

    BACKGROUND: Most patients with acute exacerbation chronic obstructive pulmonary disease (AECOPD) have respiratory failure that necessitates active correction and the improvement of oxygenation is particularly important during treatment. High flow nasal cannula (HFNC) oxygen therapy is a non-invasive respiratory aid that is widely used in the clinic that improves oxygenation state, reduces dead space ventilation and breathing effort, protects the loss of cilia in the airways, and improves patient comfort.
    OBJECTIVE: To compare HFNC and non-invasive positive pressure ventilation in the treatment of patients with AECOPD.
    METHODS: Eighty AECOPD patients were included in the study. The patients were in the intensive care department of our hospital from October 2019 to October 2021. The patients were divided into the control and treatment groups according to the different treatment methods with 40 patients in each group. Differences in patient comfort, blood gas analysis and infection indices were analyzed between the two groups.
    RESULTS: After treatment, symptoms including nasal, throat and chest discomfort were significantly lower in the treatment group compared to the control group on the 3rd and 5th days (P < 0.05). Before treatment, the PaO2, PaO2/FiO2, PaCO2, and SaO2 in the two groups of patients were not significantly different (P > 0.05). After treatment, the same indicators were significantly improved in both patient groups but had improved more in the treatment group compared to the control group (P < 0.05). After treatment, the white blood cell count, and the levels of C-reactive protein and calcitonin in patients in the treatment group were significantly higher compared to patients in the control group (P < 0.05).
    CONCLUSIONS: HFNC treatment can improve the ventilation of AECOPD patients whilst also improving patient comfort, and reducing complications. HFNC is a clinically valuable technique for the treatment of AECOPD.

    背景:传统上,常规微生物培养方法已用于检测慢性骨髓炎的病原微生物。然而,已发现这些方法的检出率低,复杂的感染治疗的精确指导。这项研究采用宏基因组下一代测序(mNGS)来检测慢性骨髓炎中的这些微生物,主要目的有三个:1)。对慢性骨髓炎中病原微生物的组成有更深入的了解。2).比较mNGS和实验室中使用的标准培养方法之间的微生物检出率,以增强传统培养方法的有效性。3).探讨mNGS在病因诊断中的潜力。
    方法:收集2021年1月至2021年12月临床证实的50例慢性骨髓炎的术中骨组织样本,并进行mNGS和微生物检测,分别。骨科医生结合临床表现和相关检查确定病原体。
    结果:培养方法获得29株需氧及孤雌生殖厌氧菌,3种特定的厌氧菌,和1个酵母样真菌。36种需氧和单性厌氧菌,11种特定的厌氧细菌,通过mNGS获得1种酵母样真菌,检出2株结核分枝杆菌(MTB)。然而,mNGS与培养法的总体阳性检出率差异无统计学意义(P=0.07),两者在检测需氧菌和部分厌氧菌方面无统计学意义(P=0.625)。但是,mNGS在检测厌氧菌和结核分枝杆菌方面明显优于培养(P<0.05)。
    结论:mNGS方法提高了我们对慢性骨髓炎病原微生物分布的认识。传统的培养方法有助于分离和培养好氧和兼性厌氧菌,和真菌,也用于抗菌药物敏感性试验。然而,mNGS在检测厌氧菌方面表现出卓越的能力,MTB,和混合感染细菌。这一发现为改善实验室微生物培养和检测条件提供了宝贵的指导。因此,mNGS应明智地用于慢性骨髓炎,并且可以对某些难以培养的微生物实施PCR,比如MTB。
    Traditionally, conventional microbiological culture methods have been used to detect pathogenic microorganisms in chronic osteomyelitis. However, these methods have been found to have a low detection rate, complicating the precise guidance of infection treatment. This study employed metagenomic next-generation sequencing (mNGS) to detect these microorganisms in chronic osteomyelitis with three main objectives: 1). Gain a deeper understanding of the composition of pathogenic microorganisms in chronic osteomyelitis. 2). Compare the microbial detection rates between mNGS and the standard culture methods used in laboratories to enhance the effectiveness of the traditional culture methods. 3). Explore the potential of mNGS in etiological diagnosis.
    Fifty clinically confirmed intraoperative bone tissue samples of chronic osteomyelitis from January 2021 to December 2021 were collected and subjected to mNGS and microbiological testing, respectively. The orthopaedic surgeon combined clinical manifestations and related examinations to determine the causative pathogens.
    The culture method obtained 29 aerobic and parthenogenic anaerobic bacteria, 3 specific anaerobic bacteria, and 1 yeast-like fungus. Thirty-six aerobic and parthenogenic anaerobic bacteria, 11 specific anaerobic bacteria, and 1 yeast-like fungus were obtained by mNGS, and 2 Mycobacterium tuberculosis(MTB) strains were detected. However, there was no significant difference in the overall positive detection rate between mNGS and the culture method (P = 0.07), and the two were not statistically significant in detecting aerobic and partly anaerobic bacteria (P = 0.625). But, mNGS was significantly superior to culture in detecting anaerobic bacteria and Mycobacterium tuberculosis (P<0.05).
    The mNGS method has enhanced our understanding of the distribution of pathogenic microorganisms in chronic osteomyelitis. Traditional culture methods help isolate and cultivate aerobic and facultative anaerobic bacteria, and fungi, and are also utilized for antibacterial drug sensitivity tests. However, mNGS has shown superior capabilities in detecting anaerobic bacteria, MTB, and mixed infection bacteria. This finding offers invaluable guidance for improving laboratory microbial culture and detection conditions. Hence, mNGS should be judiciously used for chronic osteomyelitis, and PCR can be implemented for certain difficult-to-culture microorganisms, such as MTB.

    癫痫是一种常见的神经系统疾病,具有多种癫痫发作类型,复杂的病因,机制不明确。其诊断主要依靠临床病史,但是脑电图也是重要的辅助检查。最近,脑成像技术在癫痫的诊断中越来越受到重视,而常规磁共振成像可以检测某些癫痫患者的癫痫灶。然而,一些患者的脑磁共振成像结果正常。近年来新的分子影像学逐渐发展,并已应用于癫痫的诊断,导致病变检出率提高。然而,必须阐明这些技术在脑磁共振阴性的癫痫患者中的应用。因此,通过查阅相关文献,总结相关资料,以期提高对分子影像学在癫痫中的应用价值的认识。
    Epilepsy is a common neurological disease with various seizure types, complicated etiologies, and unclear mechanisms. Its diagnosis mainly relies on clinical history, but an electroencephalogram is also a crucial auxiliary examination. Recently, brain imaging technology has gained increasing attention in the diagnosis of epilepsy, and conventional magnetic resonance imaging can detect epileptic foci in some patients with epilepsy. However, the results of brain magnetic resonance imaging are normal in some patients. New molecular imaging has gradually developed in recent years and has been applied in the diagnosis of epilepsy, leading to enhanced lesion detection rates. However, the application of these technologies in epilepsy patients with negative brain magnetic resonance must be clarified. Thus, we reviewed the relevant literature and summarized the information to improve the understanding of the molecular imaging application value of epilepsy.
