Recent research on inherited metabolic diseases in children / 中国当代儿科杂志

With the improvement in the research level and the diagnosis and treatment technology of inherited metabolic diseases (IMD), the research on pediatric IMD in China has made great progress, but there is still some distance from the international level. Due to the vast territory of China and the uneven distribution of medical resources, the regional characteristics of IMD remain unclear in China, and there are many problems and difficulties in early diagnosis and treatment. Therefore, it is necessary to improve the understanding of pediatric IMD among pediatricians, so as to improve the diagnosis and treatment level, achieve an early identification, diagnosis, and treatment of pediatric IMD, and effectively reduce the fatality and disability rates of children with IMD. This article reviews the research progress of IMD in children in China, and analyzes the features of representative IMDs. Citation:Chinese Journal of Contemporary Pediatrics, 2022, 24(3): 326-331.

Risk factors of progressive brain contusion and relationship with outcome / 浙江大学学报·医学版

<p><b>OBJECTIVE</b>To investigate the risk factors of progressive brain contusion and to evaluate their impact on patients' outcome.</p><p><b>METHODS</b>One hundred and thirty two patients with traumatic brain contusion were enrolled in the study, including 70 cases with progressive contusion and 62 cases with non-progressive contusion. The risk factors were investigated with univariate and multivariate Logistic regression analysis.</p><p><b>RESULTS</b>The univariate analysis showed that Glasgow Coma Score (GCS) at admission, contusion volume at the first brain CT scans, midline shift, combined with skull fracture, subarachnoid hemorrhage, epidural hematoma, subdural hematoma, location of brain contusion, D-dimer levels, combined with type 2 diabetes were associated with progressive brain contusion. Multivariate Logistic regression analysis showed that GCS at admission, contusion volume at the first CT scans, combined with subarachnoid hemorrhage, combined with type 2 diabetes were the independent risk factors for disease progression. The outcome in the progressive group was more aggravated than that in non-progressive group (P = 0.001).</p><p><b>CONCLUSION</b>Patients with disturbance of consciousness, the larger contusion volume, combined with subarachnoid hemorrhage and diabetes are at risk for progressive brain contusion and unfavorable outcome.</p>

[Alternatively activated macrophages in helminth infections].

Macrophages not only initiate and modulate immune responses, but also are the final effector cells. Recent studies suggested that macrophages conventionally associated with IFN-gamma dominant Th1-type responses and also playing an essential role in the Th2-type inflammatory response, exhibit a quite different activation from the classically activated macrophages (CAM Phi) stimulated during Th1-type responses, therefore named as alternatively activated macrophages (AAM Phi). AAM Phi have multiple effects during helminth infection, including control of inflammatory reaction, contribution to fibrosis and repair at the site of injury, and anti-helminth effect. This article reviews recent findings regarding the role of AAM Phi in the development of disease and host protection following helminth infection.
