Synchronous Double Primary Tumors of Liver (Small Cell Neuroendocrine Carcinoma and Hepatocellular carcinoma): A Case Report.

This study presents a case of dual primary liver cancer involving small cell neuroendocrine carcinoma and hepatocellular carcinoma. The 58-year-old Chinese male patient, who has a medical history of viral hepatitis B, presented with right upper abdominal pain persisting for one month. Imaging studies indicated the presence of multiple liver masses in segments V and VII-VIII, as well as a mass in the left lung.

Development and validation of prognostic nomogram for patients with metastatic gastric adenocarcinoma based on the SEER database.

The aim of this study was to investigate the prognostic factors affecting overall survival in patients with metastatic gastric adenocarcinoma and to establish a nomogram prediction model for comprehensive clinical application. Data from 2370 patients with metastatic gastric adenocarcinoma between 2010 and 2017 were retrieved from the surveillance, epidemiology, and end results database. They were randomly divided into a training set (70%) and a validation set (30%), univariate and multivariate Cox proportional hazards regressions were used to screen important variables that may affect overall survival and to establish the nomogram.

Chromosome-level assembly of Gymnocypris eckloni genome.

Gymnocypris eckloni is widely distributed in isolated lakes and the upper reaches of the Yellow River and play significant roles in the trophic web of freshwater communities. In this study, we generated a chromosome-level genome of G. eckloni using PacBio, Illumina and Hi-C sequencing data.

16S rRNA Gene Amplicon Sequencing of Gut Microbiota from Naked Carp (Gymnocypris przewalskii) in Qinghai Lake, China.

Naked carp (Gymnocypris przewalskii) is a second-grade animal under state protection of China. We report 16S rRNA gene amplicon analysis of the gut microbiota of Gymnocypris przewalskii. The three most abundant phyla are , , and , and the six most abundant genera are , , , , , and .

[Association between body mass index and physical fitness index among children and adolescents].

Objective: To explore the relationship between body mass index (BMI) and physical fitness index (PFI) among children and adolescents.

Methods: The study sample included 8941 students aged 7 to 18 years in Anhui who attended the Physical Fitness and Health Surveillance program of Chinese School Students, in 2010. Within each sex- and age-specific group, students were classified into five BMI categories which were: very low, BMI<5th percentile; low, BMI≥5th but <15th percentiles; normal, BMI≥15th but <85th percentiles; high, BMI≥85th but <95th percentiles; and very high, BMI≥95th percentiles.

[Relationship between waist circumference development curve of children and hypertension and risk of hypertension].

Objective: The 85th percentile of waist circumference (WC) is considered an appropriate cutoff for Chinese children in the prediction of cardiovascular risks in previous researches, but the risk for hypertension of moderate WC maybe underestimated. The purpose of this study was to understand the characteristics of the WC curve trajectory of children with hypertension and to determine the appropriate cutoffs for waist circumference for Chinese school-age children and adolescents for predicting hypertension risk factors.

Methods: A total of 8194 Han children aged 7 - 17 years were selected from schools in Suzhou, Hefei, and Chizhou cities in Anhui province by stratified cluster sampling.
