The birth weight of macrosomia influence the accuracy of ultrasound estimation of fetal weight at term.

Objective: To evaluate and analyze the accuracy of ultrasound estimation of the fetal weight of Macrosomia at term.

Method: The instruments used were α6(Aloka; Japan) color Doppler ultrasound imagers, and vinno 80 (feieno; China) with a frequency of 3.5 MHz.

Genomic characteristics and drug screening among organoids derived from non-small cell lung cancer patients.

Background: Patient-derived organoid (PDO) models are highly valuable and have potentially widespread clinical applications. However, limited information is available regarding organoid models of non-small cell lung cancer (NSCLC). This study aimed to characterize the consistency between primary tumors in NSCLC and PDOs and to explore the applications of PDOs as preclinical models to understand and predict treatment response during lung cancer.

Wigner distribution function of an Airy beam.

We study the Wigner distribution function (WDF) of an Airy beam. The analytical expression of the WDF of an Airy beam is obtained. Numerical and graphical results of the WDF of an Airy beam provide an intuitive picture to explain the intriguing features of an Airy beam, such as weak diffraction, curved propagation, and self-healing.

[Correlation between gene polymorphisms of Wnt signalling pathway related components and risk of gastric carcinoma: a case-control study].

Objective: To investigate correlation between polymorphisms of rs3755557 and rs1880481 located in glycogen synthase kinase 3beta gene and beta-catenin gene respectively, the products of which are components of Wnt signalling pathway, and risk of gastric carcinoma.

Methods: PCR and denaturing high-performance liquid chromatography combining with DNA sequencing were used to analyse genotype polymorphism of rs3755557 and rs1880481 of the subjects including 26 patients of gastric carcinoma and 33 patients of chronic superficial gastritis.

Results: Chi-square analysis revealed that there was no significant difference in the frequencies of alleles and genotypes of rs3755557 polymorphic site between gastric carcinoma group and control group.
