Echogenic intracardiac focus (EIF) is a common ultrasound finding during pregnancy. However, the correlation between fetal EIF and cardiac abnormality remains in dispute until now. The study aimed to examine the association of fetal EIF with chromosomal abnormality by means of chromosomal microarray analysis (CMA).

A total of 192 pregnant women with fetal EIF undergoing amniocentesis or umbilical cord blood puncture were recruited and assigned into groups A (8 cases with isolated EIF alone), B (75 cases with EIF and other cardiac malformations) and C (109 cases with EIF and extracardiac malformations). All fetuses underwent karyotyping analysis and CMA simultaneously. The detection of chromosomal abnormality and copy number variations (CNVs) were compared.

Chromosomal karyotyping identified 5 fetuses with chromosomal abnormality, including 3 cases with trisomy 21, one fetus with Turner's syndrome, and one fetus with chromosome 8 mosaicism, while CMA detected 6 additional fetuses with CNVs, including 2 fetuses with pathogenic CNVs and 4 fetuses with variants of uncertain significance (VOUS). There was no significant difference among groups A (0), B (5.33%) and C (6.42%) in terms of the prevalence of chromosomal abnormality (

> 0.05). Among the 4 fetuses with VOUS, pregnancy continued in 2 fetuses, and pregnancy was terminated in other 2 fetuses.

An isolated EIF may not correlate with chromosomal abnormality. However, CMA is recommended in fetuses with CMA complicated by other abnormal cardiac ultrasound findings, which facilitates the prediction of fetal outcomes during the genetic counseling and precision assessment of prognosis.

Human papillomavirus (HPV) is linked to various cancers in males and females. The prevalence and genotype distribution of HPV vary depending on geographical region and the immunity provided by vaccines. Investigation of HPV epidemiology is of great meaning for the development of prevention programs.

From January 2017 to September 2019, using PCR-reverse dot blot hybridisation, we determined the HPV subtypes in 2801 patients 17-89 years old at the sexually transmitted diseases (STD) clinic of Tianjin Medical University General Hospital.

The HPV infection rate was 50.79% in males and 50.64% in females. The most common HPV genotype in males and females was HPV6 (30.15% and 30.43%), followed by HPV16 (18.76% and 20.65%) and HPV11 (14.61% and 15.67%). Infection with a single HPV subtype predominated in both males and females, and the rate in males was higher than in females. By contrast, the rate of high-risk HPV (hrHPV) and low-risk HPV (lrHPV) mixed infection in females was higher than in males. Most HPV-positive patients were 20-39 years of age. The prevalence of infection with only hrHPV differed among the age groups; the peak age was 50 to 59 years.

The HPV prevalence was higher among the STD clinic outpatients than the general population. Therefore, a large-scale survey of high-risk populations is needed. It is anticipated that HPV vaccines, regular education and physical examinations may have a significant impact on the prevention of HPV-related diseases in high-risk groups.

This study aimed to directly and accurately measure the range of motion of the acromioclavicular joint through 3D reconstruction and image registration.

Thirteen healthy volunteers participated in the study. Computerized tomography (CT) was used to measure the acromioclavicular joint in four different motion poses. The images were integrated using reconstruction and registration technology, and the rotation angle range of the acromioclavicular joint was measured using 3D reconstruction. The measurements were expressed by axial angle representation. The dominant and the non-dominant sides were compared, and the difference in the axial angle of the acromioclavicular joint was compared in different postures.

The difference between the dominant and non-dominant sides in acromioclavicular motion was not significant. In the sagittal motion of the upper limb, the rotation angle of the acromioclavicular joint was greatest in a resting horizontal position, with an average of 26.1°. In this position, 34.6% of flemioclavicular joint. SCH 900776 solubility dmso The rotational motions of the acromioclavicular joint are bilaterally symmetrical and can be used as a reference for comparative study. The maximum range of motion of the acromioclavicular joint during rotation was found in the resting horizontal position. The clinical examination and post-treatment evaluation of the acromioclavicular joint's rotation function can therefore be targeted in this range.

Cumulative evidence has demonstrated that breast cancer was the most commonly diagnosed cancer in women. Despite growing evidence for a link between serotonin and tumorigenesis, research on the expression of serotoninergic systems in the human breast cancer cell and tissue has only rarely been reported.

First, immunofluorescence staining, ELISA and Western blotting were used to detect serotonin and melatoninergic systems in various breast cancer cell types. Then, serotonin expression was evaluated in the cultures of TPBC cell line BT-474 and TNBC cell line MDA-MB-231 using immunofluorescence assay. To further explore the diagnostic role of serotonin in breast cancer, serotonin expression was conducted in the TPBC and TNBC tumor sections by immunostaining analysis.

Our results suggested that both human breast cancer cells and human breast epithelial cell line could synthesize serotonin and melatonin. Unlike melatonin, serotonin levels varied significantly between human breast cancer and breast epithelial cell line (
