TCP family as plant specific transcription factor, plays an important role in different aspects of plant development. In order to screen TCP family members in tobacco, the homologous sequences of tobacco and Arabidopsis TCP family were identified by genome-wide homologous alignment. The physicochemical properties, phylogenetic relationships and cis-acting elements were analyzed by bioinformatics. The homologous genes of AtTCP3/AtTCP4 were screened, and RT-qPCR was used to detect the changes of gene expression upon 20% PEG6000 treatment. The results show that tobacco contains 63 TCP family members. Their amino acid sequence length ranged from 89 aa to 596 aa, and their protein hydropathicity grand average of hydropathicity (GRAVY) ranged from -1.147 to 0.125. The isoelectric point (pI) ranges from 4.42 to 9.94, the number of introns is 0 to 3, and the subcellular location is all located in the nucleus. The results of conserved domain and phylogenetic relationship analysis showed that the tobacco TCP family can be divided into PCF, CIN and CYC/TB1 subfamilies, and each subfamily has a stable sequence. The results of cis-acting elements in gene promoter region showed that TCP family genes contain low docile acting elements (LTR) and a variety of stress and metabolic regulation related elements (MYB, MYC). Analysis of gene expression patterns showed that AtTCP3/AtTCP4 homologous genes (NtTCP6, NtTCP28, NtTCP30, NtTCP33, NtTCP42, NtTCP57, NtTCP63) accounted for 20% PEG6000 treatment significantly up-regulated/down-regulated expression, and NtTCP30 and NtTCP57 genes were selected as candidate genes in response to drought. The results of this study analyzed the TCP family in the tobacco genome and provided candidate genes for the study of drought-resistance gene function and variety breeding in tobacco.

Objective To investigate the relationships of nutritional status and length of stay (LOS) with phase angle (PA) in patients with severe craniocerebral injury. Methods A total of 100 patients [Glasgow Coma Scale (GCS) score ≤8 points] admitted outside the department of neurology were selected as study objects. Body composition analysis and blood samples were used to determine the intracellular and extracellular water content, skeletal muscle, PA, prognostic nutritional index (PNI) and LOS. Patients were divided into low PA group (n=42) and normal PA group (n=58) based on PA values. Body composition related indexes, PNI and LOS were compared between the two groups. The correlation between PA and each index was analyzed. The influencing factors of malnutrition were analyzed. The influencing factors of malnutrition were analyzed. Results Intracellular water, total body water, body cell content and PNI in the low PA group were significantly lower, and LOS was significantly longer than that in the normal PA group (P < 0.05). PA was positively correlated with intracellular water, extracellular water, total body water, skeletal muscle, body cell content, bone mineral content, basal metabolic rate and PNI (P < 0.05), while PA was negatively correlated with LOS (P < 0.05). PA (OR=5.441, P=0.001, 95%CI, 2.011 to 14.719) and LOS (OR=8.373, P < 0.001, 95%CI, 3.079 to 22.765) were the influential factors in the occurrence of malnutrition. Conclusion PA is significantly correlated with nutritional status and LOS in patients with severe craniocerebral injury.

OBJECTIVE: To explore the genetic basis for a child with metachromatic leukodystrophy (MLD). METHODS: Clinical data of the patient was collected. Genomic DNA was extracted from peripheral blood samples of the child and his family members. Potential variant was screened by whole exome sequencing (WES), and candidate variant was verified by Sanger sequencing. The pathogenicity the variant was analyzed by multiple sequence alignment of the amino acid sequence and three-dimensional model prediction of its protein product. RESULTS: The child was found to harbor compound heterozygous variants c.257G>A (p.R86Q) and c.467del (p.G156Afs*6) of the ARSA gene, among which the c.467del (p.G156Afs*6) frameshift variation was unreported previously. Multiple sequence alignment showed that the site of the c.257G>A (p.R86Q) missense variant is highly conserved. Three-dimensional structure modeling analysis showed that the partial deletion due to the p.G156Afs*6 variant may cause significant alteration of the structure of ARSA protein. CONCLUSION The discovery of novel variant in ARSA has enriched the mutational spectrum of MLD and may facilitate the understanding of the genotype-phenotype correlation of MLD.

This consensus can not only benefit to clinical nursing practice, but also lay the foundation for the development of guideline, and it still needs further theoretical and empirical research verification.

OBJECTIVE: To detect potential mutations of the PKHD1 gene in two pedigrees affected with infantile polycystic kidney disease. METHODS: Clinical data and peripheral venous blood samples were collected from the probands and their parents as well as fetal amniotic fluid cells. Genome DNA was extracted from the peripheral blood samples and amniotic fluid cells. Exons 32 and 61 of the PKHD1 gene were amplified with PCR and subjected to direct sequencing. RESULTS: The proband of pedigree 1 was found to carry c.4274T>G (p.Leu1425Arg) mutation in exon 32 and c.10445G>C (p.Arg3482Pro) mutation in exon 61 of the PKHD1 gene, which were inherited from her father and mother, respectively. The fetus has carried the c.4274T>G (p.Leu1425Arg) mutation. In pedigree 2, the wife and her husband had respectively carried a heterozygous c.5979_5981delTGG mutation and a c.9455delA mutation of the PKHD1 gene. No chromosomal aberration was found in the umbilical blood sample, but the genetic testing of their fetus was failed. Based on software prediction, all of the 4 mutations were predicted to be pathogenic. CONCLUSION PKHD1 c.4274T>G (p.Leu1425Arg), c.10445G>C (p.Arg3482Pro), c.5979_5981delTGG and c.9455delA were likely to be pathogenic mutations. The results have facilitated genetic counseling and prenatal diagnosis for the two pedigrees.

Objective To acknowledge the quality of life (QOL) in patients after lung transplantation and to explore related factors. Methods A cross- sectional study design and a convenience sampling were performed in this research. Totally 30 patients after lung transplantation were investigated. The questionnaires which used to explore the quality of life were Short Form 36 Health Survey Questionnaires (SF-36) and Revised Airways Questionnaires 20 (AQ20-R). Related state were surveyed by questionnaires consisted of demographic questionnaires, Self-rating Anxiety Scale (SAS), Self-rating Depression Scale (SDS) and Medical Coping Mode Questionnaires (MCMQ). Statistical analysis was performed by SPSS 20.0 software. Correlation analysis and multivariate analysis were performed using Pearson linear correlation analysis and multi-linear regression. Results The scores among the 8 dimensions of SF-36 were(34.48±16.73)-( 71.63±22.83), lower than those of norms(Z=-9.684--2.817, P<0.05 or 0.01). Somatic pain scored the highest (71.63±22.83), while physiological function scored the lowest (34.48±16.73). The mean score of AQ20-R was 7.93±5.21. The major two problems that manifested QOL were: uncomfortable feeling of lung caused by strong scent, smog or perfume, exhausted feeling after having a cold. The mean scores of SAS and SDS were 44.33±9.33,48.05±9.80, higher than those of norms, which were 33.80 ± 5.90, 41.88 ± 10.57 (t=6.1833, 3.4458, P < 0.01). The scores among the 3 dimensions of MCMQ were 8.93 ± 2.08, 16.10 ± 2.28, 3.63 ± 1.33 and the differences were significant in 3 dimensions compared with those norms, which were 19.48±3.81, 14.44±2.97, 8.81±3.17(t=-27.7281, 3.9885,-21.3878, P<0.01). Conclusions In SF-36, role-physical of patients after lung transplantation was the worst dimension, while bodily pain was the best dimension of QOL. The QOL of patients after lung transplantation were almost worse than normal people. The related factors of QOL in patients after lung transplantation maybe:anxiety, depression and medical coping style.
