Heterozygous CARD9 mutation favors the development of allergic bronchopulmonary aspergillosis / 中华医学杂志(英文版)

BACKGROUND@#Previous research demonstrated that a homozygous mutation of g.136372044G>A (S12N) in caspase recruitment domain family member 9 ( CARD9 ) is critical for producing Aspergillus fumigatus -induced ( Af -induced) T helper 2 (T H 2)-mediated responses in allergic bronchopulmonary aspergillosis (ABPA). However, it remains unclear whether the CARD9S12N mutation, especially the heterozygous occurrence, predisposes the host to ABPA.@*METHODS@#A total of 61 ABPA patients and 264 controls (including 156 healthy controls and 108 asthma patients) were recruited for sequencing the CARD9 locus to clarify whether patients with this heterozygous single-nucleotide polymorphisms are predisposed to the development of ABPA. A series of in vivo and in vitro experiments, such as quantitative real-time polymerase chain reaction, flow cytometry, and RNA isolation and quantification, were used to illuminate the involved mechanism of the disease.@*RESULTS@#The presence of the p.S12N mutation was associated with a significant risk of ABPA in ABPA patients when compared with healthy controls and asthma patients, regardless of Aspergillus sensitivity. Relative to healthy controls without relevant allergies, the mutation of p.S12N was associated with a significant risk of ABPA (OR: 2.69 and 4.17 for GA and AA genotypes, P = 0.003 and 0.029, respectively). Compared with patients with asthma, ABPA patients had a significantly higher heterozygous mutation (GA genotype), indicating that p.S12N might be a significant ABPA-susceptibility locus ( aspergillus sensitized asthma: OR: 3.02, P = 0.009; aspergillus unsensitized asthma: OR: 2.94, P = 0.005). The mutant allele was preferentially expressed in ABPA patients with heterozygous CARD9S12N , which contributes to its functional alterations to facilitate Af -induced T H 2-mediated ABPA development. In terms of mechanism, Card9 wild-type ( Card9WT ) expression levels decreased significantly due to Af -induced decay of its messenger RNA compared to the heterozygous Card9S12N . In addition, ABPA patients with heterozygous CARD9S12N had increased Af -induced interleukin-5 production.@*CONCLUSION@#Our study provides the genetic evidence showing that the heterozygous mutation of CARD9S12N , followed by allele expression imbalance of CARD9S12N , facilitates the development of ABPA.

The role and action mechanism of signaling proteins in the occurrence and development of neuroblastoma / 国际药学研究杂志

Neuroblastoma(NB)is the most common extracranial solid tumor derived from the sympathetic ner- vous system in childhood. The location of NB is variable, the pathogenesis is complex and the clinical manifestations vary greatly. The prognosis is good in low or medium risk NB patients but bad in high risk NB patients. Recent studies have shown that the occurrence, growth, proliferation, migration and invasion of NB as well as the prognosis of NB pa- tients are associated with the abnormal expression of signaling proteins in NB, including the transcriptional regulators, kinases, and receptors, etc.. This article reviews the role and action mechanism of different signaling proteins in the oc- currence and development of NB.

Update of diagnosis and treatment for congenital hypogonadotropic hypogonadism / 国际儿科学杂志

Congenital hypogonadotropic hypogonadism,mainly characterized by absence of puberty and infertility,is a disorder due to deficient production,secretion or activity of gonadotropin-releasing hormone or gonadotropins.Multiple causative genes have been found till now,and other factors like environmental endocrine disruptors also participate in promoting the disease at the same time.Common diseases in this category are Kall-mann syndrome,Prader-Willi syndrome and multiple pituitary hormone deficiency.Neonatal period and early in-fancy are golden time for diagnosis of the disorder.Constitutional growth delay of puberty should be considered in the differential diagnosis for adolescent patients.Therapeutic schedule should be selected according to age, gender and demand for fertility.The treatment can be sexual hormone replacement,gonadotropin therapy and pul-satile pump gonadotropin-releasing hormone.A timely diagnosis and treatment can induce and maintain second sexual characteristics,enhance the male spermatogenesis and female ovulation and reduce psychological problems caused by the disorder.This article is to review the update in diagnosis and treatment of the disorder.

Effects of corticotropin releasing factor on dendritic development of hippocampal neurons / 国际药学研究杂志

Stress exerts profound effects on cognitive and emotional functions. As a regulator of response to stress, the corticotropin releasing factor (CRF) during stress impacts organism function through hypothalamic-pituitary-adrenal axis. Recent research has shown that dendritic branches were abnormal and dendritic spine was lost under stress. In contrast, stressed mice with CRF receptor 1 (CRFR1) deficiency or CRFR1 antagonist exhibited normal dendritic morphology of hippocampal neurons. The structure and related factors expression of hippocampal neurons were affected by CRFR1 as a G protein-coupled receptor (GPCR), but the molecular mechanism about CRF-induced direct injury effect on hippocampal neurons has been poorly understood. The paper reviews the research progress on the contribution of stress activated CRF-CRF receptor signaling to the structure and related factors of hippocampal neurons.

Expression of miR-9 in H/RS cells and its regulation on target PRDM1 / 白血病·淋巴瘤

Objective To explore the expression of miR-9 in H/RS cells and its regulation on target PRDM1.Methods miR-9 expression in normal CD19+ B-cell subsets and eight lymphoma cell lines was detected by fluorescence quantitative RT-PCR and in situ hybridization (ISH),for quantification and location,respectively.Chemically synthesizcd antisense oligonucleotide of miR-9 was transiently transfected into L428 for its silence,and the PRDM1 expression was tested.Results Fluorescence quantitative RT-PCR showed that the expression of miR-9 in L428 cells was marked higher than that of normal CD19+ B-cell subsets and other lymphoma cell lines (the expression of miR-9 in L428 cells was 47-fold of OCI-Ly1,50-fold of Raji cells,7-fold of EBV+ immortalized B cell line,and 6-fold of ALCL cell line).ISH indicated that miR-9 located in cytoplasm,it was a diffuse and strong positive in L428,scattered and weak in DLBCL and Burkitt' s lymphoma cell lines,while negative in KARPAS-299 or Jurkat cell lines.Transient down-regulation of miR-9 in L428 leded to the increase of PRDMI protein.Conclusion miR-9 plays the role of cancer gene in cHL,and may exert a potential function in regulating terminal B cell differentiation through a post transcription regulation of PRDM1 gene.

Pneumonia relevant to lung transplantation and pathogen distribution / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>Pneumonia is the most common cause of morbidity and mortality in lung transplant (LT) recipients. The aim of the present study was to evaluate the incidence, etiology, risk factors and prognosis of pneumonia in LT recipients.</p><p><b>METHODS</b>The LT cohort consisted of 28 recipients receiving LT in Beijing Chao-Yang Hospital from August 2005 to April 2011. Data collected included demographic data, underlying disorders, time and type of transplant, follow-up information, date of last follow-up, and patient status. A retrospective analysis was made of observational data that were prospectively collected.</p><p><b>RESULTS</b>Twenty-two patients of 28 LT recipients had 47 episodes of pneumonia throughout the study period. Thirtyeight episodes of pneumonia in 19 recipients occurred post-LT with a median follow-up of 257.5 days (1-2104 days), the incidence of pneumonia was 192.4 episodes per 100 LT/year and its median time of onset was 100.5 days (0-946 days) post-transplantation. Bacteria, virus and fungi accounted for 62%, 16% and 15% of the microbial pathogens, respectively. The most frequent were Pseudomonas aeruginosa (20%), cytomegalovirus (CMV) (15%), and Aspergillus fumigatus (10%). A total of 29% (11/38) of pneumonias occurred in the first month post-LT, and then the incidence decreased gradually. The incidence of CMV pneumonia was 25% (7/28) with a median time of 97 days (10-971 days). More than one bacterial infection and CMV infection were independent risk factors for aspergillus infection. The incidence of pulmonary tuberculosis (TB) was 18% (5/28), and the history of TB was a risk factor for TB relapse. There were 58% (7/12) of recipients who died of infection, and 71% (5/7) of these died in the first year after LT.</p><p><b>CONCLUSIONS</b>Pneumonia is still a major cause of morbidity and mortality in LT recipients. The most frequent microorganisms were Pseudomonas aeruginosa, CMV, and Aspergillus fumigates. The incidence of CMV pneumonia decreases with a delayed median time of onset. More than one incidence of bacterial infection and CMV infection are independent risk factors for aspergillus infection. LT recipients are at high risk for TB, and the history of TB is a risk factor for TB relapse.</p>
