Objectives: The aim of bisphosphonate treatment in patients with metastatic bone disease is to prevent metastatic skeletal morbidity and prevent cancer treatment-induced skeletal damage. The classical recommendation of Zoledronic acid treatment is to be given indefinitely as intravenous infusion every 3 to 4 weeks until patients' health deteriorates. Data on zoledronic acid's long-term effectiveness and safety are insufficient, and some recent literatures start to consider 12-weekly administration as a reasonable alternative in order to minimize the adverse effects. Methods: A systematic search was conducted based on PRISMA guideline to identify relevant studies through PubMed, Google Scholar, and Cochrane database. A total of 5 studies (2867 patients) were included, divided into outcome analysis, processed using Review Manager 5.3. Results: The search of electronic databases yielded a total of 299 entries. Five studies were included in the qualitative and quantitative synthesis following the steps of identifying, screening, determining eligibility, eliminating duplicates, and excluding studies. Out of a total of 2.867 patients, 1.427 received ZA for 12 weeks and 1.440 received ZA for 4 weeks, making up the total number of patients included in this meta-analysis. Each trial had a comparable one-year follow-up duration after ZA was given. We discovered that the incidence of adverse effects varied significantly between the two groups. In contrast, there is no statistically significant difference in the rates of SRE, ONJ, renal dysfunction, or death between the two groups. Conclusion: Our systematic review and meta-analysis reveals that 12-week intervals of zoledronic acid is as effective as the standard 4-week interval in terms of skeletal related event, jaw osteonecrosis, renal dysfunction, and mortality rate. However, the standard 4-week intervals led to higher rate of adverse effects.

. Objectives: Our previous study indicated that USP1 inhibitor ML323 downregulated USP1 in colorectal cancer (CRC) cells, but the specific mechanism was still unknown. Methods: CRC cells were lysed for immunoblotting to detect protein expressions. Quantitative real-time PCR was performed to examine mRNA levels. Cycloheximide chase assays were carried out to evaluate the half-life of USP1. Co-immunoprecipitation was used to analyze the polyubiquitination of USP1. Results: USP1 protein stability was enhanced by the proteasome inhibitor MG132 in CRC cells. The wild-type USP1 was upregulated by MG132, but not its catalytic mutant. Additionally, the polyubiquitination of USP1 was enhanced by MG132 as well, which indicated USP1 was degraded through the ubiquitin-proteasome pathway. Meanwhile, we confirmed ML323 downregulated USP1 expression in CRC cells, and cycloheximide chase assay also revealed ML323 reduced USP1 protein stability. Further results showed ML323-induced USP1 downregulation and destabilization were abolished by MG132. Moreover, USP1 protein destabilization was not reversed by the caspase inhibitor Z-VAD, which further suggested ML323-induced USP1 downregulation was not dependent on the effects of cell death in CRC cells. Conclusion: Our results showed USP1 was auto-ubiquitinated, and ML323 destabilized USP1 through the ubiquitin-proteasome pathway in CRC cells, providing a theoretical basis for anti-CRC drugs’ development targeting USP1.
. 目的:我们前期研究发现USP1抑制剂ML323下调结直肠癌(CRC)细胞中的USP1,但具体机制尚不清楚。方法:对结直肠癌细胞进行裂解免疫印迹检测蛋白表达。采用实时荧光定量PCR检测mRNA水平。采用环己亚胺追踪法测定USP1的半衰期。采用共免疫沉淀法分析USP1的多泛素化作用。结果:蛋白酶体抑制剂MG132增强了CRC细胞中USP1蛋白的稳定性。野生型USP1被MG132上调,但其催化突变体没有上调。此外,MG132还增强了USP1的多泛素化,说明USP1是通过泛素-蛋白酶体途径降解的。同时,我们证实ML323下调了USP1在CRC细胞中的表达,环己亚胺追踪实验也显示ML323降低了USP1蛋白的稳定性。进一步的结果表明,MG132消除了ml323诱导的USP1下调和不稳定。此外,caspase抑制剂Z-VAD不能逆转USP1蛋白的不稳定,这进一步表明ml323诱导的USP1下调并不依赖于CRC细胞死亡的影响。结论:我们的研究结果表明USP1是自泛素化的,ML323在CRC细胞中通过泛素-蛋白酶体途径使USP1失稳,为开发针对USP1的抗CRC药物提供了理论基础。

Objectives: Linked color imaging (LCI) helps to differentiate minor mucosal changes, which can be objectively judged by red–green–blue pixel brightness. However, whether this color analytic model based on pixel brightness can be applied to diagnose Helicobacter pylori infection remains unknown. Methods: Consecutive adult patients with indications and underwent esophagogastroduodenoscopy for the 1 st time were enrolled in the training (n=166) and validation (n=79) set. Demographic and clinical characteristics were recorded. Target region in gastric antrum was pictured before biopsy for rapid urea test, and pixel brightness was calculated by MATLAB software. Results: In training set, 25 patients had H. pylori infection. Pixel brightness for R and B in patients with H. pylori infection was greatly higher than those in patients without H. pylori infection (R: 210.203±27.233 vs. 196.401±29.018, p=0.043; B: 127.621±26.112 vs. 125.334±27.812, p=0.025). At the cut off of R = 210 and B = 127, the specificity and sensitivity were 0.696 and 0.701. In validation set, 10 patients had H. pylori infection and the findings were consistent with those in training set. Conclusion: Color analytic model based on pixel brightness under LCI was useful in diagnosing H. pylori infection in gastric antrum.
目的:联色成像(LCI)有助于区分轻微的粘膜变化,可通过红绿蓝像素亮度客观判断。然而,这种基于像素亮度的颜色分析模型能否应用于幽门螺杆菌感染的诊断仍是未知的。方法:将有适应证且首次行食管胃十二指肠镜检查的连续成年患者纳入训练组(n=166)和验证组(n=79)。记录人口学和临床特征。活检前对胃窦靶区进行快速尿素检测,并通过MATLAB软件计算像素亮度。结果:训练集中有25例患者发生幽门螺杆菌感染。幽门螺杆菌感染患者R、B的像素亮度显著高于未感染患者(R: 210.203±27.233 vs. 196.401±29.018,p=0.043;B: 127.621±26.112 vs. 125.334±27.812,p=0.025)。在R = 210和B = 127的截点处,特异性和敏感性分别为0.696和0.701。验证组中有10例患者存在幽门螺杆菌感染,与训练组结果一致。结论:LCI下基于像素亮度的颜色分析模型可用于胃窦幽门螺杆菌感染的诊断。

Pancreatic Enzymes Elevation and Emergency Setting: Pancreatitis or Not Pancreatitis? That is the Question 胰酶升高和急诊情况:胰腺炎还是非胰腺炎?这就是问题所在
Pub Date : 2023-01-01 DOI: 10.14744/ejmo.2023.75981

Dear Editor, Notwithstanding often no clinically evident acute pancreatitis findings are found, a serum pancreatic enzyme elevation is found in up to 80% of critically ill patients.[1] In an emergency setting, in fact, the diagnosis of acute pancreatitis can be misleading due to various reasons, hence concomitant patients’ clinical conditions (e.g. hemodynamic instability, mechanical ventilation) and the establishment of rapidly evolving physiopathological mechanisms. Does an enzyme increase justify the diagnosis of pancreatitis? Actually no. Although a three-time greater titer than upper limits represents one of the recognized diagnostic criteria, findings of hyperamylasemia and/or hyperlipasemia could lead to several interpretations, such as the evolution of severe acute pancreatitis, as defined by the Atlanta criteria, pancreatic complications in patients admitted for other pathologies or a mere biochemical increase in the absence of clinical-radiological signs attributable to pancreatic inflammation. Furthermore, the enzymatic titer does not represent a prognostic factor or an index of progression to a necrotic or haemorrhagic state. Although, a diagnosis of acute pancreatitis at onset can established on the basis of an enzymatic increase supported by suggestive clinical findings, the enzymatic dosage cannot be considered predictive of progression, as in case of the C-reactive protein. Furthermore, in the early stages of the disease, the extensive use of diagnostic radiologic investigations (<96 hours) has no role.[2] As reported by Weaver et al.,[3] in a retrospective analysis including 192 emergency patients, 36.45% had hyperamylasemia but none met clinical or radiological criteria for acute pancreatitis. Furthermore, only 9.4% in this cohort was attributable to an increase in the pancreatic serum isoform. The authors therefore concluded by recommending caution in the dosage and interpretation of the titers of serum amylase in critically ill patients. If on the one hand these evidences represent an explicit recommendation for a prompt and exhaustive nosological classification of hyperamylasemia that could mislead to an erroneous diagnosis, on the other they suggest the need for a critical review of the diagnostic criteria of acute pancreatitis where laboratory findings as far as clinical and radiological findings could lead to a reduced diagnostic power in critically ill patients.

亲爱的编辑,尽管通常没有临床明显的急性胰腺炎发现,但高达80%的危重患者发现血清胰酶升高。[1]事实上,在急诊情况下,由于各种原因,急性胰腺炎的诊断可能会产生误导,从而导致患者伴随的临床状况(如血流动力学不稳定、机械通气)和快速发展的生理病理机制的建立。酶升高是否可以作为胰腺炎的诊断依据?实际上没有。虽然三倍以上的滴度是公认的诊断标准之一,但高淀粉酶血症和/或高脂血症的发现可能导致几种解释,例如根据亚特兰大标准定义的严重急性胰腺炎的发展,因其他病理入院的患者的胰腺并发症或仅仅是生化增加而没有可归因于胰腺炎症的临床放射学征象。此外,酶滴度并不代表预后因素或进展到坏死或出血状态的指标。虽然急性胰腺炎发病时的诊断可以建立在酶促增加的基础上,并得到临床表现的支持,但酶促剂量不能像c反应蛋白那样被认为是病情进展的预测因素。此外,在疾病的早期阶段,广泛使用诊断性放射学检查(<96小时)没有作用。[2]Weaver等[3]报道,在192例急诊患者的回顾性分析中,36.45%的患者患有高淀粉酶血症,但没有人符合急性胰腺炎的临床或放射学标准。此外,该队列中只有9.4%归因于胰腺血清亚型的增加。因此,作者建议在危重患者中谨慎使用血清淀粉酶的剂量和滴度。一方面,这些证据明确建议对可能导致错误诊断的高淀粉酶血症进行迅速而详尽的分类学分类,另一方面,它们表明需要对急性胰腺炎的诊断标准进行严格审查,因为实验室结果以及临床和放射学结果可能导致对危重患者的诊断能力降低。Mirko Barone,1 Massimo Ippoliti,1 Felice mucilli1,2

Furthermore, in the early stages of the disease, the extensive use of diagnostic radiologic investigations (<96 hours) has no role.[2] As reported by Weaver et al.,[3] in a retrospective analysis including 192 emergency patients, 36.45% had hyperamylasemia but none met clinical or radiological criteria for acute pancreatitis. Furthermore, only 9.4% in this cohort was attributable to an increase in the pancreatic serum isoform. The authors therefore concluded by recommending caution in the dosage and interpretation of the titers of serum amylase in critically ill patients. If on the one hand these evidences represent an explicit recommendation for a prompt and exhaustive nosological classification of hyperamylasemia that could mislead to an erroneous diagnosis, on the other they suggest the need for a critical review of the diagnostic criteria of acute pancreatitis where laboratory findings as far as clinical and radiological findings could lead to a reduced diagnostic power in critically ill patients.
