CXCL10 is a potential biomarker and associated with immune infiltration in human papillary thyroid cancer.

Background: In recent years, the annual incidence of thyroid cancer (TC) has increased, with papillary thyroid cancer (PTC) identified as the most commonwinwordpathological type accounting for approximately 80% of all thyroid cancer cases. The tumor microenvironment is known to play a vital role in tumor information transmission and immune detection.

Methods: In the present study, we examined gene expression data from 518 patients with PTC.

Ultrasonic evaluation of congenital vaginal oblique septum syndrome: A study of 21 cases.

The aim of the present study was to investigate the ultrasound features and classify the lesion types of congenital vaginal oblique septum syndrome (CVOS) in 21 patients prior to surgery. Grey-scale pelvic ultrasound was performed to evaluate the uterus, vagina and kidneys in 21 patients with suspected CVOS. Ultrasound features, including the presence of a double uterus, hematocolpos masses and renal absence, in CVOS types I, II and III were studied and compared with intra-operative results and the results of surgery.

Hollow Carbon Microspheres/MnO Nanosheets Composites: Hydrothermal Synthesis and Electrochemical Behaviors.

This article reported the electrochemical behaviors of a novel hollow carbon microspheres/manganese dioxide nanosheets (micro-HC/nano-MnO) composite prepared by an in situ self-limiting deposition method under hydrothermal condition. The results of scanning electron microscopy reveal that MnO nanosheets homogeneously grow onto the surface of micro-HC to form a loose-packed microstructure. The quantity of MnO required in the electrode layer has thereby been reduced significantly, and higher specific capacitances have been achieved.

Diagnosis of the cavo-hepato-atrial pathway in Budd-Chiari syndrome by ultrasonography.

The aim of this study was to investigate the ultrasonic features of the cavo-hepato-atrial pathway in Budd-Chiari syndrome (BCS), by which blood is drained from the occluded inferior vena cava (IVC) to the right atrium via hepatic veins. Ultrasonograms from 11 patients with BCS with cavo-hepato-atrial pathways were retrospectively studied. Doppler ultrasound was used to observe the direction of the flow and measure the velocity of the blood-draining vessels.

[Enrichment of trace iron with activated carbon in Bi-based superconductor powder and determination by inductively coupled plasma atomic emission spectroscopy].

A new method for determination of trace iron in superconductor powder by ICP-AES was proposed. The instrument parameters were optimized, and the matrix effects as well as the method of eliminating interferences were also studied systemically. The results showed that matrix interference was serious when the amount of matrix increased, and the repeatability was poor, so it was necessary that separation and preconcentration were used to improve the accuracy and precision.

[Determination of trace nickel in bi-based superconductor powder by inductively coupled plasma atomic emission spectroscopy after separation with anion exchange resin and extraction with methylbenzene].

A new method for the determination of trace nickel in superconductor powder by ICP-AES was proposed. The instrument parameters were optimized, and the matrix effects as well as the method of eliminating interferences were also studied systemically. The results showed that matrix interference in the superconductor powder was serious when the amount of matrix increased, and the repeatability as well as the accuracy was poor, so it was necessary to used separation and preconcentration to improve the accuracy and precision.

[Correction of spectral interferences with mutual interference coefficient matrix for determination of impurities in Bi-based superconductor powder by inductively coupled plasma emission spectrometry].

In the present paper a method was proposed for the determination of Fe, Cr, Ni, Si, Al and Ba in Bi-based superconductor powder (BSCCO, Bi(2-x), Pb(x)Sr2Ca2Cu3O8) by inductively coupled plasma atomic emission spectrometry(ICP-AES). The operation parameters for ICP-AES were optimized, and the influences of acid kind and concentration were examined. The interferences of matrix elements Bi, Sr, Pb, Ca and Cu in Bi-based superconductor powder on the determination of impurities were studied systematically.
