Soil macro-aggregates are the main location for soil organic carbon (SOC) sequestration, which is of great significance to improve soil fertility. This study aimed to understand the mechanisms of the organic carbon (OC) sequestration in macroaggregates and improve crop yield in wheat fields on the loess plateau. With the aggregate-density fractionation method, an eight-year experiment was conducted to investigate the following three factors: ① the effects of long-term fertilization on OC fractions within macroaggregates; ② the variation characteristics of OC fractions within macroaggregates, including coarse particulate organic carbon (cPOC), fine particulate organic carbon (fPOC), intra-microaggregate particulate organic carbon (iPOC), free silt and clay particulate carbon (s+c_f), and intra-microaggregate silt and clay particulate carbon (s+c_m); ③ and the relationships between them and SOC input and yield formation.

Background: Monogenic lupus is defined as systemic lupus erythematosus (SLE)/SLE-like patients with either dominantly or recessively inherited pathogenic variants in a single gene with high penetrance. However, because the clinical phenotype of monogenic SLE is extensive and overlaps with that of classical SLE, it causes a delay in diagnosis and treatment. Currently, there is a lack of early identification models for clinical practitioners to provide early clues for recognition.

Background: The role of type I interferon (IFN-I) signaling in systemic lupus erythematosus (SLE) has been well established. However, unanswered questions remain regarding the applicability of these findings to pediatric-onset SLE. The aim of this review is to provide an overview of the novel discoveries on IFN-I signaling in pediatric-onset SLE.

Article Synopsis
  • A study focused on adenosine deaminase 2 deficiency (DADA2) in a Chinese population was conducted to analyze clinical characteristics and responses to treatment, using data from 17 rheumatology centers.
  • Thirty patients were identified, with most showing symptoms like systemic inflammation and vasculitis; the median ages for disease presentation and diagnosis were 4.3 years and 7.8 years, respectively.
  • The research concluded that genetic screening and testing are crucial for early diagnosis, recommending TNF inhibitors as first-line treatment, and hematopoietic stem cell transplantation for specific cases.

  • Progressive pseudorheumatoid dysplasia (PPRD) is a rare genetic disorder mostly found in the Chinese population, and this study aimed to analyze its genetic and clinical characteristics in these patients.
  • Researchers performed genetic tests on 105 individuals, identifying 33 variants associated with PPRD, with many being unique to Chinese patients and specific phenotypic features that correlate with the variants.
  • Results showed that certain genetic variants, particularly the hotspot variant c.624dupA, were linked to more severe disease manifestations, including later onset and increased joint involvement, especially affecting elbow and shoulder joints.

Article Synopsis
  • The study evaluated the effectiveness and safety of the safe triangular working zone (STWZ) method in percutaneous vertebroplasty for patients with spinal metastases affecting the back part of the vertebrae.
  • A total of 87 patients were split into two groups: one group received the STWZ approach, while the other did not, with outcomes such as pain relief and tumor recurrence analyzed over time.
  • Results indicated that the STWZ method led to better cement filling and lower tumor recurrence rates without severe complications, suggesting it as a promising technique for treating spinal metastases.

Article Synopsis
  • - Aicardi-Goutieres syndrome (AGS) is a challenging inflammatory disorder often leading to high mortality rates, with limited research data specifically from China, highlighting the need for better understanding its clinical presentation and diagnostic criteria.
  • - In a study of 23 Chinese AGS patients, the majority (82.6%) experienced symptoms before age 3, with common neurological issues and skin manifestations; notable findings included intellectual and language disabilities, and various dysfunctions such as liver and thyroid issues.
  • - Elevated expression of interferon-stimulated genes was observed, suggesting a systemic nature of AGS, with diagnosis recommended for early-onset patients showing specific symptoms, as exemplified by one recorded death in the study.

Blau syndrome (BS) is a monogenic autoinflammatory disease caused by mutations in nucleotide-binding oligomerization domain containing 2 (NOD2). BS is characterized by the clinical triad of granulomatous dermatitis, arthritis and recurrent uveitis. Due to the low incidence of BS and the lack of treatment studies with large samples, a specific treatment scheme has not been established.

Background: The nucleotide-binding oligomerization domain-like receptor protein 12 (NLRP12)-autoinflammatory disorder (NLRP12-AD) is a rare autoinflammatory disease characterized by recurrent fever, rash as well as musculoskeletal symptoms, which is rarely reported in Asian populations.

Methods: Three cases of NLRP12-AD presented to our hospital were studied after parental consents were obtained. Clinical presentations were recorded on a standardized case report form.

  • Systemic-onset juvenile idiopathic arthritis (SoJIA) is a severe form of arthritis in children, and researchers are investigating how gut microbiome imbalances might relate to this condition.
  • * The study analyzed fecal microbiota from SoJIA patients and healthy kids to find correlations with clinical symptoms.
  • * Results showed significant differences in microbiota, with lower Firmicutes/Bacteroidetes ratios and reduced levels of certain bacteria in SoJIA patients compared to healthy controls.

As a crucial event involved in the metastasis and relapse of esophageal cancer, c-Met overexpression has been considered as one of the culprits responsible for the failure in patients who received radiochemotherapy. Since c-Met has been confirmed to be pivotal for cell survival, proliferation and migration, little is known about its impact on the regulation of radiosensitivity in esophageal cancer. The present study investigated the radiosensitization effects of c-Met inhibitor foretinib in ECA-109 and TE-13 cell lines.

Purpose: Magnetic resonance angiography (MRA) is an important diagnosis method for the detection of intracranial aneurysms (IAs), but it is not useful for differentiating between IA and infundibular dilatation (ID) in patients in whom imaging shows an intracranial protrusion with a branch artery at its top. The objective of this study was to introduce a new approach-measurement of the outflow angle (OA)-for differentiating between IA and ID in such cases.

Methods: The study included 7 patients with a total of 9 protrusions.
