ABSTRACT
Objective To investigate the differentially expressed genes of urine samples from renal fibrosis model and carry out bioinformatics analysis.Methods Rat renal fibrosis model was constructed with the method of unilateral ureteric obstruction.Urine were collected from the rats with unilateral obstructive nephropathy and sham group, respectively.Total RNA was extracted and sequencing library was established.Differential expression mRNA were analyzed by GO and KEGG pathway.Known pre-miRNA were detected and novel lncRNA family were classified.Results Compared with the sham group urine, 813 up-regulated mRNA/lncRNA and 213 down-regulated mRNA/lncRNA were collected from the urine of renal fibrosis rats.Conclusions There are significant differential expression profile in urine samples between renal fibrosis rat group and the shame group.With high-throughput transcriptome sequencing and bioinformatics analysis, the exciting possibility was raised for better understanding renal pathologies and development of new diagnostic biomarkers.
ABSTRACT
Objective To investigate the pathogen and inspection methods of the middle-aged women with constipation and evaluate the accuracy and clinical application of imaging to constipation.Methods First colonic transit test were used to 98 cases of middle-aged women who were diagnosed constipation by doctors,then air-barium double contrast examination were applied.Defecation radiography or simulation rectum defecography were used to those who were diagnosed as outlet obstruction.According to the measure target and diagnostic criteria of professor LU,the results were studied.Results 6 cases were abnormal within 8 cases who were inspected by barium enema.14cases were abnormal within 16 cases who were inspected by defecation radiography.Colonic transit test were used to 74 cases and only 6 cases were normal.16 cases were true slow transmission and 20 cases were false slow transmission.52 cases were outlet obstruction.20 volunteers were inspected by suspension barium sulfate and simulation rectum defecography.Conclusions Air-bariun double contrast examination could discover the organic disease and abnormal of rectum.colonic transit test,defecation radiography and simulation rectum defecography were simply and perfect methods to discover the pathogen of constipation.
ABSTRACT
Objective To explore clinical characteristics of severe pre-eclampsia and eclampsia complicated with reversible posterior leukoencephalopathy syndrome(RPLS).Methods Clinical data of 31 cases of severe pre-eclampsia and eclampsia complicated with RPLS were studied retrospectively.ResulIs These 31 cases with RPLS accounted for 48% of those with eclampsia,.and all presented with hypertension,headache and disturbalice of vision,24 cases with seizure episodes,19 cases with nausea and vomiting and 13 with continuous dysphoria after seizure.Neuroradiologic findings showed edema predominantly in the bilateral posterior cerebral white matter,especially in occipital-parietal lobe,with low density lesions in CT and long T1 and T2 signals in brain MRI. Conclusions Severe pre-eclampsia and eclampsia tended to complicate with RPLS,presenting severe hypertension,headache,disturbance of vision and recurrent seizure as major clinical manifestations.
ABSTRACT
As one of the important areas in proteomics,glycoproteome is in the spotlight currently.In this paper,the description of glycoproteins,the enrichment methods of glycoproteins/glycopeptides,the identification approaches of glycoproteins/glycopeptides and the application of glycoproteome were overviewed.
