Application of contrast-enhanced ultrasound in renal space-occupying lesion puncture biopsy.

Objective: The purpose of this study was to investigate the utility of contrast-enhanced ultrasound (CEUS) in percutaneous renal space-occupying lesion puncture biopsy.

Methods: Ultrasound (US)-guided percutaneous needle biopsies were performed on 55 patients with renal space-occupying lesions, and the results were analyzed retrospectively. The US group included 36 patients receiving conventional US, and the contrast-enhanced ultrasound (CEUS) group included 22 patients, including 19 patients receiving CEUS directly and 3 patients receiving additional enhanced ultrasound due to the first conventional ultrasound puncture failure.

Parallel subgenome structure and divergent expression evolution of allo-tetraploid common carp and goldfish.

How two subgenomes in allo-tetraploids adapt to coexistence and coordinate through structure and expression evolution requires extensive studies. In the present study, we report an improved genome assembly of allo-tetraploid common carp, an updated genome annotation of allo-tetraploid goldfish and the chromosome-scale assemblies of a progenitor-like diploid Puntius tetrazona and an outgroup diploid Paracanthobrama guichenoti. Parallel subgenome structure evolution in the allo-tetraploids was featured with equivalent chromosome components, higher protein identities, similar transposon divergence and contents, homoeologous exchanges, better synteny level, strong sequence compensation and symmetric purifying selection.

The correlation between ultrasonographic features, bFGF, and the local invasiveness of thyroid papillary carcinoma.

The present study aimed to investigate the correlation between ultrasonographic features, basic fibroblast growth factor (bFGF), and the local invasiveness of papillary thyroid carcinoma (PTC).A total of 350 samples of thyroid nodules were collected. Routine ultrasonography was performed before the operation and routine pathological diagnosis and bFGF detection were performed after the operation.

[Comparative study of main components of ginseng on immune function of rats].

Ginseng and its effective components are famous for their influence to enhance human immunity, regulate endocrine and antioxidant action. However, the different effects of different components are not clear. In this study, Wistar rats were used to study the effects of main components of ginseng, including total ginsenoside, panaxadiol saponins, panaxtrol saponin and ginseng polysaccharide.

[Heritability of body weight and fork length for Oncorhynchus masou masou].

Body weight and body length have been considered as the most important production traits for the fish genetic improvement. For cold-water fish, body length was usually substituted by fork length. In order to estimate the heritability of body weight and fork length of the sixth generation Oncorhynchus masou masou, which was introduced into China, the method of unbalanced nest design and an artificial insemination technigue were used.

[The genetic diversity of diploid and triploid crucian carp from six populations in Heilongjiang River System].

Twelve microsatellite markers from silver crucian carp were used to investigate the genetic structuring of the diploid and triploid crucian carp from six natural populations in Heilongjiang River System. In the six populations, the number of average allele (A) is from 5.8 to 6.
