ABSTRACT

A 3-year-old male patient was diagnosed with neurofibromatosis type 1(NF1) for two years. The patient has multiple neurofibromas in retroperitoneum, lumbococcygeal paravertebral, lumbosacral spinal canal, and foramina. Due to retroperitoneal mass compression, the child suffered from urological complications such as hydronephrosis, ureterdilation, neurogenic bladder, etc., which seriously affected the urination function and resulted in multiple surgical treatments. Currently, the patient has been treated with mitogen activates extracelluar signal-regulated kinases(MEK) inhibitor selumetinib targeted therapy, and has voluntarily urinated, and his general state is better than before medication. The diagnosis and treatment of this case reflects the importance of multidisciplinary collaboration in the diagnosis and treatment of rare diseases.

ABSTRACT

Objective The aim of this study was to evaluate whether PRDM16 gene polymorphisms were associated with dyslipidemia. Methods The polymorphisms of rs2651899, rs2236518, rs870171, and rs2282198 in PRDM16 gene in 528 participants were genotyped by the method of snapshot or ligase detection reaction. The genotype differences and the allele differences between the case group and the control group were analyzed. Linkage disequilibrium analysis was performed with SHE-sis online software. The interaction between rs2651899, rs2236518, rs870171, rs2282198 and gender, age, BMI were analyzed by MDR software. Results The frequency of allele A in rs2651899 locus was significantly higher in low HDL-C group compared with that in control group[OR(95%CI)=1.32(1.02-1.71), P=0.033]. The frequency of A/C genotype in rs870171 was significantly different between LDL-C abnormal group and control group[OR(95% CI)=1.97(1.01-3.86), P=0.037]. There may be interaction between rs2236518 and sex, which is a risk factor for low HDL-C[Model Ⅱ: OR(95% CI)=1.958(1.366-2.809), P<0.01]. There may be interactions among rs2651899, rs2236518, rs870171, and rs2282198, which seemed to be risk factors for lower HDL-C[Model Ⅳ: OR(95% CI)=3.991(2.707-5.884), P<0.01]. rs870171, rs2282198 may have interaction with age, which is a risk factor for high LDL-C [Model Ⅶ: OR(95%CI)=3.991(2.707-5.884), P<0.01]. Conclusion Allele A of rs2651899 may be a risk factor to low HDL-C. Under the codominant inheritance patterns, genotype A/C of rs870171 may be a risk factor to high LDL-C. In addition, there may be interaction between SNPs with gender and age.

ABSTRACT

Large-scale, rod-like nanostructures of LaPO4:Eu3+ phosphors were synthesized using a simple hydrothermal method. The phase composition, structure and morphology of the final products were characterized by XRD, FE-SEM and TEM. Highly crystalline material was obtained as confirmed by X-ray powder diffraction measurements. The FE-SEM and TEM observations indicate that the obtained LaPO4:Eu3+ nanorods have a diameter of about 10-20 nm, and a length of about 100-600 nm. Meanwhile, the excitation and emission spectra of the products at room temperature were measured using a fluorescence spectrometer. The effects of pH and Eu3+-doping on the morphology and luminescence properties of the as-prepared powders were investigated. The photoluminescence (PL) spectra show that the emission intensity of the LaPO4:Eu3+ phosphors improved with increases in concentrations of Eu3+ from 3 mol% to 14 mol%, and then decreased for higher concentrations.
