Clinical characteristics and serum inflammatory markers of community-acquired mycoplasma pneumonia in children

Background

To compare the demographic and clinical features, laboratory and imaging findings in mycoplasma pneumoniae pneumonia (MPP) children with non-MPP (NMPP) children and general MPP (GMPP) children with refractory MPP (RMPP) children and analysis the relationship with the severity of disease.

Methods

The study included 265 children with MPP and 230 children with NMPP in the Affiliated Changzhou No. 2 People's Hospital of Nanjing Medical University from 2020 to 2021. The children with MPP included RMPP (n = 85) and GMPP (n = 180). Demographic and clinical characteristics, laboratory and imaging findings of all children were measured as baseline data within 24 h after admission and the differences between MPP and NMPP, RMPP and GMPP patients were compared. ROC curves were used to evaluate the diagnostic and predictive value of different indicators for RMPP.

Results

Fever duration and hospital stay in children with MPP were longer than those with NMPP. The number of patients with imaging features of pleural effusion, lung consolidation and bronchopneumonia in MPP group was significantly higher than that in NMPP group. Compared with NMPP group, the levels of C-reactive protein (CRP), procalcitonin (PCT), serum amyloid A (SAA), erythrocyte sedimentation rate (ESR), lactic dehydrogenase (LDH), prothrombin time (PT), fibrinogen (FIB) and D-dimer and inflammatory cytokines (interleukin [IL]-6, IL-8, IL-10 and IL-1β) in MPP group were significantly higher (P < 0.05). The clinical symptoms and pulmonary imaging findings were more severe in RMPP group. The levels of white blood cell (WBC), CRP, PCT, SAA, ESR, alanine aminotransferase (ALT), LDH, ferritin, PT, FIB, D-dimer and inflammatory cytokines in RMPP group were higher than those in GMPP group. There was no significant difference in the level of lymphocyte subsets between the RMPP and GMPP group. IL-6, IL-10, LDH, PT, D-dimer and lung consolidation were independent risk factors for RMPP. IL-6 levels and LDH activity were good predictors of RMPP.

Conclusion

In conclusion, there were differences in clinical characteristics and serum inflammatory markers between MPP group and NMPP group, RMPP group and GMPP group. IL-6, IL-10, LDH, PT and D-dimer can be used as predictive indicators for RMPP.     

剪切波弹性成像技术评估子痫前期胎盘弹性的临床价值

目的评价剪切波弹性成像技术对子痫前期的诊断价值。 方法前瞻性纳入2019年10月至2020年12月在常州第二人民医院超声科检查的晚孕期孕妇177名。根据临床诊断将孕妇分为健康组152名和子痫前期组25例。采用单因素分析比较2组间一般临床资料、二维超声、彩色多普勒超声参数及胎盘（母体面和胎儿面）杨氏模量值（Emean、Emax、Emin）间的差异。采用Spearman相关分析胎盘杨氏模量值与胎儿脐血流参数间的相关性,并建立受试者工作特征曲线,评价胎盘杨氏模量值诊断子痫前期的诊断效能。 结果健康组与子痫前期组孕妇的羊水指数、胎盘厚度以及脐动脉血流收缩/舒张期速度比（S/D）、阻力指数（RI）、搏动指数（PI）比较,差异均无统计学意义（P均＞0.05）。除胎盘母体面Emin以外,子痫前期组孕妇胎盘母体面Emean、Emax及胎儿面Emean、Emax、Emin均高于健康组［（5.87±0.41）kPa vs（5.30±0.53）kPa;8.67（8.30,9.66）kPa vs 8.01（7.56,8.50）kPa;（5.15±0.34）kPa vs（4.65±0.52）kPa;（8.07±0.70）kPa vs（7.11±0.85）kPa;（3.28±0.44）kPa vs（3.01±0.54）kPa］,差异具有统计学意义（t=-6.215、Z=-4.566、t=-6.298、t=-5.376、t=-2.430,P＜0.001、＜0.001、＜0.001、＜0.001、=0.016）。健康组和子痫前期组孕妇胎盘自身的母体面Emean、Emax、Emin均高于胎儿面,差异具有统计学意义（t=11.319、Z=-8.461、t=12.118、t=6.266、Z=-3.807、t=5.416,P均＜0.001）。相关性分析显示2组中各杨氏模量值与脐动脉血流的S/D、RI、PI值均无显著相关性（P均＞0.05）。当截断值为5.85 kPa时,胎盘母体面的Emean值诊断子痫前期的效能最佳,其敏感度、特异度、准确性分别为68.0%、85.5%、83.1%。 结论子痫前期孕妇胎盘的杨氏模量值高于健康孕妇。剪切波弹性成像技术可通过评价胎盘硬度辅助子痫前期的诊断。

Reduced telomere length in colorectal carcinomas

Purpose: Telomeres play a key role in the maintenance of chromosome integrity and stability, and telomere shortening is involved in initiation and progression of malignancies. The aim of this study was to determine whether telomere length is associated with the colorectal carcinoma. Patients and methods: A total of 148 colorectal cancer (CRC) samples and corresponding adjacent non-cancerous tissues were evaluated for telomere length, P53 mutation, and cyclooxygenase-2 (COX-2) mutation detected by fluorescent immunohistochemistry. Telomere length was estimated by real-time PCR. Samples with a T/S>1.0 have an average telomere length greater than that of the standard DNA; samples with a T/S<1.0 have an average telomere length shorter than that of the standard DNA. Results: Telomeres were shorter in CRCs than in adjacent tissues, regardless of tumor stage and grade, site, or genetic alterations (P=0.004). Telomere length in CRCs also had differences with COX-2 status (P=0.004), but did not differ with P53 status (P=0.101), tumor progression (P=0.244), gender (P=0.542), and metastasis (P=0.488). There was no clear trend between T/S optimal cut-off values (<1 or > 1) and colorectal tumor progression, metastasis, gender, P53 and COX-2 status. Conclusion: These findings suggesting that telomere shortening is associated with colorectal carcinogenesis but does not differ with tumor progression, gender, and metastasis.
