TLR4-MyD88 signaling is involved in the spinal neurons during the full length of recovery from transection of the motor branch of the femoral nerve in mice.

This study was designed to see the expression of toll-like receptor 4 (TLR4) and downstream molecules including myeloid differentiation factor 88 (MyD88) and interleukin 1-β (IL-1β) in the spinal cord as peripheral nerve injury recovered in mice. We established a model of femoral nerve injury (FNI) in C57BL/6 mice by transection of the motor branch of the femoral nerve, followed by retrograde labeling to show the according motor neurons in the anterior horn of the spinal cord pars lumbar. We observed the motor function recovery of the injured hind limbs using behavioral tests.

Hsp70 Gene Polymorphisms Are Associated With Disease Susceptibility and HRQOL Improvement in Chinese Han Population With Systemic Lupus Erythematosus.

Objectives: The aim of this study is to investigate whether heat shock protein 70 (Hsp70) gene polymorphisms are implicated in systemic lupus erythematous (SLE) susceptibility, the efficacy of glucocorticoids (GCs) treatment, and improvement of health-related quality of life.

Methods: A total of 499 SLE patients and 499 controls were included in a case-control study, and 468 SLE patients treated with GCs for 12 weeks were involved in a follow-up study. Patients who completed the 12-week follow-up were divided into GCs-sensitive and GCs-insensitive group by using the SLE disease activity index.

Copy number variations and polymorphisms in HSP90AB1 and risk of systemic lupus erythematosus and efficacy of glucocorticoids.

The aim of our study was to assess the associations of HSP90AB1 copy number variations (CNVs) with systemic lupus erythematosus (SLE) risk and glucocorticoids (GCs) efficacy, as well as the relationship between HSP90AB1 single-nucleotide polymorphisms (SNPs) and GCs efficacy. HSP90AB1 CNVs and SLE risk were analysed in 519 patients and 538 controls. Patients treated with GCs were followed up for 12 weeks and were divided into sensitive and insensitive groups to investigate the effects of CNVs (419 patients) and SNPs (457 patients) on the efficacy of GCs.

Associations of HSP90AA2 gene polymorphisms with disease susceptibility, glucocorticoids efficacy and health-related quality of life in Chinese systemic lupus erythematosus patients.

Although the current glucocorticoids (GCs) treatment for systemic lupus erythematosus (SLE) is effective to a certain extent, the difference in therapeutic effect between patients is still a widespread problem. Some patients can have repeated attacks that greatly diminish their quality of life. This study was conducted to investigate the relationship between HSP90AA2 polymorphisms and disease susceptibility, GCs efficacy and health-related quality of life (HRQoL) in Chinese SLE patients.

Association study of TRAP1 gene polymorphisms with susceptibility and glucocorticoids efficacy of systemic lupus erythematosus.

New functions of tumor necrosis factor receptor-associated protein 1 (TRAP1) have been investigated recently. This study explored if TRAP1 gene polymorphisms in patients with systemic lupus erythematosus (SLE) are associated with disease susceptibility and the efficacy of glucocorticoids (GCs). A case control study was performed to explore the association between TRAP1 gene polymorphisms and susceptibility to SLE, then the SLE patients included in the case control study were followed to investigate the relationship between TRAP1 gene polymorphisms and efficacy of GCs.

Association of HSP90B1 genetic polymorphisms with efficacy of glucocorticoids and improvement of HRQoL in systemic lupus erythematosus patients from Anhui Province.

The aim of this study was to investigate the associations between HSP90B1 gene polymorphisms and the efficacy of glucocorticoids (GCs) and the improvement of health-related quality of life (HRQoL) in Anhui patients with systemic lupus erythematosus (SLE). A total of 305 patients with SLE were recruited to the study. These patients were treated with GCs for 12 weeks and classified into two groups (sensitivity and insensitivity) according to the response to GCs measured by the scores on SLE disease activity index (SLEDAI).

Transverse myelopathy occurring with intrathecal administration of methotrexate and cytarabine chemotherapy: A case report.

Paraplegia following spinal injury is a rare complication subsequent to the administration of intrathecal chemotherapy; however, it is also one of the rare clinical features of central nervous system leukemia (CNSL). Distinguishing between the two is extremely important. The present study reports the case of a 46-year-old man who was diagnosed with acute lymphoblastic leukemia and subsequently achieved remission in the blood and bone marrow following the initial course of chemotherapy.

Flow cytometry used to identify histiocytic sarcoma: A case report.

Histiocytic sarcoma (HS) is an extremely rare but aggressive malignancy of hematopoietic origin. The diagnosis of HS mainly relies on pathological morphology and immunohistochemical staining combined with clinical symptoms. However, whether histiocytic sarcoma can be detected using flow cytometry (FCM) is not clear.

Doxycycline inhibits leukemic cell migration via inhibition of matrix metalloproteinases and phosphorylation of focal adhesion kinase.

Doxycycline, a tetracycline-based antibiotic, has been reported to attenuate melanoma cell migration through inhibiting the focal adhesion kinase (FAK) signaling pathway. However, it remains to be elucidated whether doxycycline exerts this effect on leukemia cell migration. The present study aimed to examine the role of doxycycline in leukemia cell migration.

Analyzing gene expression profile in K562 cells exposed to sodium valproate using microarray combined with the connectivity map database.

To explore the mechanism underlying antileukaemia effect of sodium valproate, the growth and survival of the K562 cell line were investigated. Global profiles of gene expression in K562 cells exposed to sodium valproate were assessed and validated. The differentially expressed genes identified were further used to query the connectivity map database to retrieve a ranked list of compounds that act on the same intracellular targets as sodium valproate.

Using an exon microarray to identify a global profile of gene expression and alternative splicing in K562 cells exposed to sodium valproate.

To investigate the effect of valproate treatment on the K562 cell line, a model for chronic myelogenous leukaemia, the growth and survival of the K562 cell line were investigated using the Annexin-V/PI dual staining method, and global profiles of gene expression and alternative splicing in K562 cells were assessed using exon microarrays. A significant increase in cell apoptosis was observed in valproate-exposed K562 cells using flow cytometry. A total of 628 transcripts were identified as being significantly differentially expressed.
