Background: Pulmonary alveolar proteinosis (PAP) is a rare lung disease characterized by the accumulation of phospholipoproteinaceous material in the alveoli. Cases of PAP complicated with tuberculosis are much more complex and have rarely been well recorded.
Case Summary: We describe a 21-year-old Han Chinese patient with suspicious lung infection associated with mild restrictive ventilatory dysfunction and diffusion reduction.
Antituberculosis drug-induced liver injury (ATDILI) has received increasing attention globally, which may limit the effectiveness of antituberculosis (anti-TB) treatment. Many host genetic determinants of ATDILI have been identified recently. As little knowledge is currently available about the association between aldehyde dehydrogenase 1 family member A1 (ALDH1A1) polymorphisms and ATDILI, the association between their variants and the susceptibility to ATDILI was investigated.
View Article and Find Full Text PDFTuberculosis (TB) is one of the most common infectious diseases globally. The surfactant protein C (SFTPC), which is involved in innate immunity and surfactant function in the lung, may contribute toward the progression of TB. The aim of the present study was to preliminarily investigate the possible association of single nucleotide polymorphisms (SNPs) in the gene with TB susceptibility and clinical phenotypes in a Western Chinese Han population.

Objective: To screen the genes with significant changes in DNA methylation level in active tuberculosis patients, we used the methylation chips and expanded the sample size to verify candidate genes.
Methods: ① This study enrolled 9 cases of active tuberculosis patients, 3 cases of latent tuberculosis patients and 3 cases of healthy controls whose age and gender were all matched. Genome DNA was extracted from peripheral blood mononuclear cell in blood samples collected from these candidates, and bisulfite conversion treatment was then conducted.

Objective: To screen and identify the gene of DNA methylation in patients with active tuberculosis.
Methods: ① This study enrolled 9 cases of active tuberculosis patients (including 3 newly diagnosed tuberculosis patients and 6 cases of retreatment of active tuberculosis patients), 3 cases of latent tuberculosis patients and 3 cases of healthy controls. Genome DNA was extracted from Peripheral Blood Mononuclear Cell and following bisulfite conversion treatment.
Aim: Although peripheral low-grade inflammation and brain-derived neurotrophic factor (BDNF) levels have been implicated in schizophrenia (SCZ), the interactions between them remain to be fully revealed. We aimed to compare BDNF and cytokines in patients with SCZ and healthy controls (HC). Additionally, we aimed to investigate the association between peripheral levels of cytokines and BDNF in patients with SCZ.

Objectives: To determine the correlation between fms-like tyrosine kinase 3 gene () expression and -internal tandem duplication (ITD) mutations in acute myeloid leukemia patients,and the association between expression of gene and clinical and laboratory features of patients.
Methods: The expression of mRNA in bone marrow (BM) leukemic cells of 128 acute myeloid leukemia (AML) patients was measured by real-time PCR.The patients were divided into two groups using the 35% expression as a cut-off point.

Objectives: To determine the correlation between gene polymorphisms in Wnt signal pathway and susceptibility of Chinese Tibetan people to tuberculosis.
Methods: A total of 488 active tuberculosis patients and 454 healthy subjects(control) were enrolled in this case-control study.Five single nucleotide polymorphisms (SNPs) in Wnt signal pathway (rs4135385 in gene,rs11001553 in gene,rs56900803 in gene,rs7832767 in gene and rs11079571 in gene) were genotyped using MassARRAY method.

Objectives: To determine the targeted regulating role of has-miR-577 and has-miR-583 on the expression of fibroblast growth factor 21 (-21) based on a constructed luciferase reporter -21 gene vector.
Methods: The site of has-miR-577 and has-miR-583 target genes -21 were predicted by the bioinformatics analyzing tools online.-21 gene fragments,combined with has-miR-577 or has-miR-583 sequences and mutant sequences,were designed and synthesized.

Objective: To determine gene variations and genotype-phenotype correlations in Duchenne/Bayesian muscular mystrophy (DMD/BMD) patients, and the association between dystrophin gene polymorphisms and clinical phenotype.
Methods: Multiplex ligation-dependent probe amplification (MLPA) was adopted to detect dystrophin gene variations in 170 patients. Sanger sequencing was performed in 3 cases with decreased peaks in MLPA results.

Aims: To investigate the distribution of epidermal growth factor receptor (EGFR) mutations, and explore any relationships with clinical characteristics in non-small-cell lung carcinoma (NSCLC) patients.
Materials And Methods: EGFR mutations were assessed by ADx-ARMS in 261 NSCLC patients from West China Hospital of Sichuan University. Relationships between EGFR mutation and clinical characteristics were analyzed by SPSS.

Background: Some reports have suggested that chronic myeloid leukemia (CML) patients have a higher prevalence of M-bcr than acute lymphoblastic leukemia (ALL) patients, which show a higher prevalence of m-bcr. However, the relationship between BCR-ABL subtypes and progression of CML and ALL remains unclear.
Materials And Methods: 354 CML chronic phase (CML-CP) patients, 26 CML blastic phase (CML-BP) patients and 72 ALL patients before treatment with BCR-ABL positive were recruited for blood routine examination and bone marrow smear cytology.
Background: To establish a reliable correction method for automated hemoglobin (HGB) measurement by minimizing the interference from blood high triglyceride (TG).
Methods: Fifty whole blood samples and 50 plasma samples containing variable TG concentrations were used to determine the centrifugation speed and time. Complete blood cell counts (CBCs) were performed by an automated hematology analyzer for 102 blood samples, in which high-level TG were artificially added.
