In Silico Analysis Revealed Five Novel High-Risk Single-Nucleotide Polymorphisms (rs200384291, rs201163886, rs193141883, rs201139487, and rs201723157) in ELANE Gene Causing Autosomal Dominant Severe Congenital Neutropenia 1 and Cyclic Hematopoiesis.

Single-nucleotide polymorphisms in the ELANE (Elastase, Neutrophil Expressed) gene are associated with severe congenital neutropenia, while the ELANE gene provides instructions for making a protein called neutrophil elastase. We identified disease susceptibility single-nucleotide polymorphisms (SNPs) in the ELANE gene using several computational tools. We used cutting-edge computational techniques to investigate the effects of ELANE mutations on the sequence and structure of the protein. Our study suggested that eight nsSNPs (rs28931611, rs57246956, rs137854448, rs193141883, rs201723157, rs201139487, rs137854451, and rs200384291) are the most deleterious in ELANE gene and disturb protein structure and function. The mutants F218L, R34W, G203S, R193W, and T175M have not yet been identified in patients suffering from SCN and cyclic hematopoiesis, while C71Y, P139R, C151Y, G214R, and G203C reported in our study are already associated with both of the disorders. These mutations are shown to destabilize structure and disrupt ELANE protein activation, splicing, and folding and might diminish trypsin-like serine protease efficiency. Prediction of posttranslation modifications highlighted the significance of deleterious nsSNPs because some of nsSNPs affect potential phosphorylation sites. Gene-gene interactions showed the relation of ELANE with other genes depicting its importance in numerous pathways and coexpressions. We identified the deleterious nsSNPs, constructed mutant protein structures, and evaluated the impact of mutation by employing molecular docking. This research sheds light on how ELANE failure upon mutation results in disease progression, including congenital neutropenia, and validation of these novel predicted nsSNPs is required through the wet lab.

Impacts of Colored Light-Emitting Diode Illumination on the Reproductive Performance and Bioactive Constituents and the Molecular Mechanism of Hypothalamus Gland in Zi-geese.

Goose is a seasonal breeding animal. Its reproduction is regulated by hypothalamus-pituitary-gonad axis and also affected by environmental factors such as light and location. Zi-goose is characterized with long egg-laying period and high egg-laying potential and belongs to the long-day type of seasonal breeding. In this study, the regulation mechanism of different lighting on reproductive performance of Zi-goose by using metabonomics analysis technology. In addition, 1,481 differential metabolites were screened out totally. 583 differential metabolites were identification in hypothalamus of Zi-goose. 196 differential metabolites were identification in pituitary of Zi-goose. 692 differential metabolites were identification in ovary of Zi-goose. Under red light condition for 12 h, expression of 433 differential metabolites were down-regulated and expression of 150 differential metabolites were up regulated in hypothalamus of Zi-goose, expression of 125 differential metabolites were down-regulated and expression of 71 differential metabolites were up-regulated in pituitary of Zi-goose, expression of 355 differential metabolites were down-regulated and expression of 337 differential metabolites were up-regulated in ovary of Zi-goose. 33 differential metabolites were closely associated with 1,264 transcripts and 400 homologous genes of related enzymes in hypothalamus of Zi-goose. 15 differential metabolites were closely associated with 163 transcripts and 47 homologous genes of related enzymes in pituitary of Zi-goose. 55 differential metabolites were closely associated with 1,255 transcripts and 360 homologous genes of related enzymes in ovary of Zi-goose. It was confirmed that four metabolic pathways were closely related to light regulation of reproductive performance of Zi-goose, namely GnRH signaling pathway, prolactin signaling pathway, thyroid hormone synthesis and ovarian steroidogenesis. Typical differential metabolites of arachidonic acid, glucose-6-phosphate, progesterone, glutathione, oxidized glutathione, testosterone, deoxyepiandrosterone and their related protein genes would play an important role in light regulation of reproductive performance of Zi-goose.

Predicting the Most Deleterious Missense Nonsynonymous Single-Nucleotide Polymorphisms of Hennekam Syndrome-Causing CCBE1 Gene, In Silico Analysis.

Hennekam lymphangiectasia-lymphedema syndrome has been linked to single-nucleotide polymorphisms in the CCBE1 (collagen and calcium-binding EGF domains 1) gene. Several bioinformatics methods were used to find the most dangerous nsSNPs that could affect CCBE1 structure and function. Using state-of-the-art in silico tools, this study examined the most pathogenic nonsynonymous single-nucleotide polymorphisms (nsSNPs) that disrupt the CCBE1 protein and extracellular matrix remodeling and migration. Our results indicate that seven nsSNPs, rs115982879, rs149792489, rs374941368, rs121908254, rs149531418, rs121908251, and rs372499913, are deleterious in the CCBE1 gene, four (G330E, C102S, C174R, and G107D) of which are the highly deleterious, two of them (G330E and G107D) have never been seen reported in the context of Hennekam syndrome. Twelve missense SNPs, rs199902030, rs267605221, rs37517418, rs80008675, rs116596858, rs116675104, rs121908252, rs147974432, rs147681552, rs192224843, rs139059968, and rs148498685, are found to revert into stop codons. Structural homology-based methods and sequence homology-based tools revealed that 8.8% of the nsSNPs are pathogenic. SIFT, PolyPhen2, M-CAP, CADD, FATHMM-MKL, DANN, PANTHER, Mutation Taster, LRT, and SNAP2 had a significant score for identifying deleterious nsSNPs. The importance of rs374941368 and rs200149541 in the prediction of post-translation changes was highlighted because it impacts a possible phosphorylation site. Gene-gene interactions revealed CCBE1's association with other genes, showing its role in a number of pathways and coexpressions. The top 16 deleterious nsSNPs found in this research should be investigated further in the future while researching diseases caused CCBE1 gene specifically HS. The FT web server predicted amino acid residues involved in the ligand-binding site of the CCBE1 protein, and two of the substitutions (R167W and T153N) were found to be involved. These highly deleterious nsSNPs can be used as marker pathogenic variants in the mutational diagnosis of the HS syndrome, and this research also offers potential insights that will aid in the development of precision medicines. CCBE1 proteins from Hennekam syndrome patients should be tested in animal models for this purpose.

Objective To investigate the relationship between the single nucleotide polymorphisms of SCN1A genes and the therapeutic effects of carbamazepine in Zhuang population with epilepsies. Methods We used Mass ARRAY-IPLEX and matrix assisted laser desorption/ionization time of flight mass spectrometry (MALDI-TOF-MS) technology to detect the SCN1A gene rs4667869 and rs10497275 genotypes in peripheral blood of186 Zhuang individuals with epileptic (66 cases in effective group and 120 cases of ineffective group) who received the standardized treatment of carbamazepine in Baise Region. The reversed phase high-performance liquid chromatography was used to determine blood drug level of carbamazepine. The correlations between the genotypes, alleles and the carbamazepine efficacy of the two groups were evaluated, respectively. We also analyzed the difference of carbamazepine's blood concentration between different genotypes. Results Three genotypes of GG, GC and CC were detected in rs4667869 locus. There were 3 genotypes of GG, GA and AA found in rs 10497275 locus.The differences in the allele distribution (χ2 = 11.790, P = 0.001) and genotype distribution (χ2= 10.655, P =0.005) of the rs4667869 locus were statistically significant between the two groups (ineffective group vs. effective group). However, there was no significant difference in allele distribution (χ2 = 3.335, P= 0.068) and genotype (χ2= 3.046, P = 0.218) for rs 10497275 locus in these two groups. Compared with the GG + GC genotype, the CC genotype of rs4667869 locus significantly reduced the antiepileptic efficacy of carbamazepine (OR = 2.800, 95％CI : 1.495～5.244). W hile there were no significant differences in blood concentration of genotype CC (t=1.273, P = 0.083) comparing with genotypes GG + GC in rs4667869. No significant differences were found in blood concentration between genotype AA and genotypes GG + GA of rs 10497275 (t= 0.963, P = 0.064). Conclusions These results suggest that the single nucleotide polymorphisms of rs4667869 in SCN1A genes could be associated with the drug resistance of carbamazepine in Zhuang population with epilepsies.

The accuracy of ultrasonography in 5500 mPas silicone-tamponade eyes / 中华实验眼科杂志

Background The ultrasonography for silicone tamponade eye is a problem in diagnosis and treatment of eye diseases,especially for the calculation of intraocular lens (IOL) power.IOL Master is usually used to the biometric measurement of the silicone tamponade eye in well-equipped hospital,but it is still disabled in serious cataractous eyes.Corrective B or A-type ultrasound methods have been used for a fewer years,but these measured results are incomparable probably due to the difference of viscosity of silicone oils.Objective This study attempted to investigate the accuracy of B-type ultrasonography for ocular axial length (AL) measurement in silicone tamponade eyes.Methods The transmitting speed of ultrasonic wave in the silicone oil was determined by comparing the outcomes between balance solution mesuring and 5 500 mPas silicone oil,and a calculating formula for corrective ocular AL in 5 500 mPas silicone filled eyes was further established.Thirty-two eyes of 30 patients who received 5 500 mPas silicone oil tamponade due to complex retinal detachment were enrolled in Qingdao Hiser Medical Group from May 2012 to March 2014.The eyes were assigned to the AL＜26 mm group (18 eyes of 16 patients) and AL≥26 mm group (14 eyes of 14 patients).B-scan ultrasound and IOL Master were used to measure the AL before the removal of the silicone oil,and the Als were measured again using A-scan ultrasound and B-scan ultrasound 3 months after the removal of the silicone oil.The outcomes were compared and the correlations were evaluated among different measuring methods.The vitrous length values before and after removal of the oils,and the diopters before and after intraocular pressure (IOP) implantation were compared to varify the results of B-type sonography for 5 500 mPas silicone-tamponade eyes.Results The transmitting speed of sound wave in 5 500 mPas silicone oil was 1 023 m/second with the conversion factor 0.668 between silicon oil eyes and vitreous cavity,and the corrected formula for AL measurement was:the length form cornea apex to the posterior pole of lens or the center of the capsular membrane+ 0.668×the length form posterior pole of lens or the center of the capsular membrane to the macular area.No significnant differences were found in the AL values among the corrective-B scan,IOL Master method,postoperative Bscan method and A-scan method both in the AL＜26 mm group and the AL≥26 mm group (AL＜26 mm:F=0.108,P =0.955;AL ≥ 26 mm:F =0.011,P =0.998),and the AL values by corrective B-scan was significantly correlated with that by IOL Master,postoperative B-scan and A-scan,respectively (AL＜26 mm group:r =0.876,0.921,0.809,all at P＜0.01;AL ≥ 26 mm group:r =0.943,0.956,0.955,all at P＜0.01).The vitreous cavity depth was (20.78 ±2.13)mm by corrective B-scan in 1 day before the removal of silicone,and that in 3 months after removal of silicone was (20.89±2.16) mm,without statistical diference between them (t =0.795,P =0.219).The actual postoperative refraction in 16 eyes with IOL was (-1.25 ± 1.69) D,and preoperative refrection was (-1.50 ±0.00) D,the difference was not statistically significant (t =0.585,P =0.284).Conclusions The biometry of B-scan ultrasonography for silicone-tamponade eye is accurate and simple,with a good feasibility in clinical measurement.

Self-assembly and chemical processing of block copolymers: a roadmap towards a diverse array of block copolymer nanostructures.

Block copolymers can yield a diverse array of nanostructures. Their assembly structures are influenced by their inherent structures, and the wide variety of structures that can be prepared especially becomes apparent when one considers the number of routes available to prepare block copolymer assemblies. Some examples include self-assembly, directed assembly, coupling, as well as hierarchical assembly, which can yield assemblies having even higher structural order. These assembly routes can also be complemented by processing techniques such as selective crosslinking and etching, the former technique leading to permanent structures, the latter towards sculpted and the combination of the two towards permanent sculpted structures. The combination of these pathways provides extremely versatile routes towards an exciting variety of architectures. This review will attempt to highlight destinations reached by LIU Guojun and coworkers following these pathways.

Microarray analysis of differentially expressed microRNAs in allergic rhinitis.

BACKGROUND: Allergic rhinitis (AR) is a common disease characterized by chronic inflammation of the nasal mucosa, but we have not fully understood the mechanism responsible for the development of AR. MicroRNAs (miRNAs) are short endogenous noncoding RNAs regulating protein translation through a mechanism known as RNA interference. To understand the molecular mechanisms of miRNA involved in the pathogenesis of AR, expressed miRNAs in AR were investigated through genomewide microarray analysis. METHODS: Mammalian miRNA microarrays containing whole human mature and precursor miRNA sequences were used for analyzing eight samples of nasal mucosa of AR and eight samples of nonallergic patients. Quantitative reverse transcriptase-polymerase chain reaction (RT-PCR) of some different expressed miRNAs was used to confirm the array results. RESULTS: The miRNA microarray chip analysis identified 421 miRNAs differentially expressed in the nasal mucosa of AR, and a total of 9 miRNAs were identified in the AR group with twofold change compared with control samples (p < 0.05). These included up-regulated miRNAs, hsa-hsa-miR-7, and hsa-miRPlus-E1194, and down-regulated miRNAs, hsa-miR-498, hsa-miR-187, hsa-miR-874, hsa-miR-143, hsa-miR-886-3p, hsa-miR-224, and hsa-miR-767-5p. RT-PCR results also confirmed that part of differentially expressed miRNAs as hsa-miR-224, hsa-miR-187, and hsa-miR-143 were down-regulated in AR. CONCLUSION: The report indicated that many miRNA expressions were altered in AR and differentially expressed miRNAs appear to be involved in the development of AR. The study of miRNAs may lead to a better understanding about the roles of identified miRNAs in the pathogenesis of AR; this would be considered in future therapeutic strategies.

Objective To investigate value of color Doppler flow imaging(CDFI) and Doppler power imaging(CDPI) in the diagnosis of choroidal detachment(CD). Methods Color Doppler ultrasound was performed in 30 cases with choroidal detachment. At the base of eyeball shape, lens, vitreous and retina examined by ultrasound, intraocular band-shaped echo was examined by CDFI and CDPI, to understand its blood flow. The observation was compared with that of surgical results. Results Of 30 cases with choroidal detachment, the diagnostic positive correspondonce of ultrasound was 80.0%, while ultrasound combined with CDFI and CDPI, the correspondence increased up to 96.7%. The sonographic features of CDFI and CDPI in choroidal detachment patients were abundant blood flow in band-shape or short stick-like. In 3 cases out of 4 cases with retinal detachment, blood flow was not abundant,their blood flow showed a sparked pattern. In addition, 14 cases combined with vitreous hemorrhage, 8 cases had vitreous opacity and 4 cases vitreous proliferation. Ultrasound diagnosis corresponded with that of clinical surgery in 27 choroidal detachment cases. Conclusions Ultrasound combined with CDFI and CDPI provide valuable references for diagnosis and treatment of choroidal detachment.

Value of ultrasound on diagnosis of posterior dislocation of the lens / 中华超声影像学杂志

ObjectiveTo investigate the value of ultrasound on the diagnosis of posterior dislocation of the lens. MethodsThe eyes of 38 patients with different kinds of posterior dislocation of the lens were examined by color Doppler ultrasound to understand location, forms, and echogram of the lens and relation with their environmental tissues. ResultsOf 38 cases, 13 cases with complete posterior dislocation of the lens, 3 cases with posterior dislocation of intraocular lens, and 22 cases with incomplete posterior dislocation of the lens were proved. Also, 4 cases with vitreous hemorrhage, 13 cases with vitreous opacity and fibrous membrane, 15 cases with posterior detachment of the vitreous, 3 cases with retinal detachment were found. In addition, 33 cases underwent vitrectomy combining lensectomy or removal of the lens, among them, diagnostic ratio of ultrasound was 100%. ConclusionsHigh practical value is shown in posterior dislocation of the lens by ultrasound as one of the important methods on the diagnosis. At the same time, it provides valuable references for choosing surgical methods of posterior dislocation of the lens.
