Objective: and its polymorphisms may be important in the physiopathology of obesity. We hypothesized that polymorphisms in gene may modify body mass index (BMI).

Methods: Thus, we systematically screened 4 tagging polymorphisms (rs4730153, rs2058540, rs3801267 and rs16872158) in gene and evaluated the association between the genetic variants and BMI in a population-based study including 442 subjects in northern China.

Results: We found that the SNP rs3801267 was significantly associated with decreased BMI ( = 0.026 in additive model), while the other 2 SNPs (rs4730153 and rs16872158) showed a borderline significant association with decreased BMI ( = 0.068 and 0.060 in additive models). Combined analysis of these 3 SNPs showed a significant allele-dosage association between the number of variant alleles and decreased BMI (  = 0.007).

Conclusions: These findings indicate that genetic variants in gene may modify individual BMI in the Chinese population.

Background: Epoxyeicosatrienoic acids (EETs) are closely associated with lipoprotein metabolism, and changes in lipid profiles potentially affect their levels and functions. Given the alterations in lipid metabolism after cholecystectomy, this study aimed to investigate the levels of four EET regioisomers (free and esterified) and lipid profiles in patients with cholelithiasis after laparoscopic cholecystectomy (LC) and explore correlations between these parameters.

Methods: This prospective study involved 40 patients with symptomatic cholelithiasis who underwent LC.

Background: Puberty has been historically considered as a time of risk and vulnerability for young people. It is associated with rapid development in the hypothalamus, which is central in the production of both stress and sex steroids. While patterns of stress reactivity are calibrated in early life, this time of rapid development may provide a means for these patterns to change.

Background: The Oswestry Disability Index (ODI) is a well-validated and widely used patient-reported outcome instrument to evaluate lumbar spinal stenosis (LSS) patients' treatment outcomes. The objective of the present study was to determine long the average interval between 2 preoperative measurements can be before a clinically significant difference of 10 points or more might appear.

Methods: This was a retrospective observational study utilizing prospectively collected data from a single university hospital database, which was compatible with the national registry.

Colorectal cancer (CRC), one of the diseases posing a threat to global health, according to the latest data, is the third most common cancer globally and the second leading cause of cancer-related deaths. The development and refinement of novel structures of small molecular compounds play a crucial role in tumor treatment and overcoming drug resistance. In this study, our objective was to screen and characterize novel compounds for overcoming drug resistance via the B Lymphoma Mo-MLV insertion region 1 (Bmi-1) reporter screen assay.
