Recognition of refractory Mycoplasma pneumoniae pneumonia among Myocoplasma pneumoniae pneumonia in hospitalized children: development and validation of a predictive nomogram model.

Backgroud: The current diagnostic criteria for refractory Mycoplasma pneumoniae pneumonia (RMPP) among Mycoplasma pneumoniae Pneumonia (MPP) are insufficient for early identification, and potentially delayed appropriate treatment. This study aimed to develop an effective individualized diagnostic prediction nomogram for pediatric RMPP.

Methods: A total of 517 hospitalized children with MPP, including 131 with RMPP and 386 without RMPP (non-RMPP), treated at Lianyungang Maternal and Child Health Care Hospital from January 2018 to December 2021 were retrospectively enrolled as a development (modeling) cohort to construct an RMPP prediction nomogram.

Case report: Fatal infantile hypertonic myofibrillar myopathy with compound heterozygous mutations in the gene.

Background: Fatal infantile hypertonic myofibrillar myopathy (FIHMM) is an autosomal recessive hereditary disease characterized by amyotrophy, progressive flexion contracture and ankylosis of the trunk and limb muscles, apnea and respiratory failure, and increased creatine phosphate levels. It is caused by mutations in the gene, and only around 18 cases including genetic mutations have been reported worldwide. All patients with FIHMM develop respiratory distress, progressive stiffness of the limbs, and have a poor prognosis.

Apoptosis in human myelodysplastic syndrome CD34+ cells is modulated by the upregulation of TLRs and histone H4 acetylation via a β-arrestin 1 dependent mechanism.

Excessive apoptosis of hematopoietic precursors in the bone marrow underlies the ineffective hematopoiesis characteristic of myelodysplastic syndrome (MDS). Toll-like receptor (TLR) signaling is abnormally activated in MDS and may be involved in excessive programmed cell death in the pathogenesis of MDS. TLRs expression and global histone H3/H4 acetylation were analyzed in bone marrow (BM) CD34+ cells from 20 lower-risk and 20 higher-risk MDS patients and 10 healthy controls.

Clinical study on the effect of Shengxueling on idiopathic thrombocytopenic purpura.

Objective: To observe the clinical effect of Shengxueling (SXL) on idiopathic thrombocytopenic purpura (ITP), and study the possible mechanism.

Methods: Eighty-six cases of ITP were randomly divided into two groups. The SXL group, 56 patients treated with SXL, a traditinal Chinese medicine and 30 patients administered with prednisone were taken as control.

[Clinical study on idiopathic thrombocytopenic purpura treated with Shengxueling Granule].

Objective: To observe the clinical effect of Shengxueling Granule (SXLG) in treating idiopathic thrombocytopenic purpura (ITP), and to study its possible mechanism.

Methods: Eighty-six cases of ITP were divided into two groups randomly. Fifty-six cases in the treatment group were treated with SXLG, a traditional Chinese medicine, and 30 cases administered with Western medicine (prednisone) were taken as control.
