Quantification of anti-sperm antibody and soluble MICA/MICB levels in the serum of infertile people of the Li ethnic group in China.

Objective: To investigate the presence of anti-sperm antibodies (AsAb) and the correlation between AsAb positivity and the expression of soluble major histocompatibility complex class I chain-related A and B (sMICA or sMICB) in the sera of infertile people of the Li nationality from Hainan, China.

Method: A total of 136 people (68 couples) from five villages in the Wuzhishan region, Hainan province participated in this study. Among them, 31 couples were included in the fertile group and 37 couples in the infertile group.

Serum soluble major histocompatibility complex class I-related chain A/B expression in patients with alcoholic liver disease in Hainan Li community.

Background/aims: To study the expression and clinical significance of serum soluble major histocompatibility complex class I-related chain A/B (sMICA/B), and its correlation with percentage of CD4(+), CD8(+), and NK cells, Liver fibrosis screening test, and liver enzymes in alcoholic liver disease (ALD).

Methods: Hainan Li ALD patients (n = 141) and healthy Li subjects (n = 100) were enrolled for the study. Liver enzymes were measured using automatic biochemical analyzer and Liver fibrosis screening test was used to study the correlation.

Differences in caspase-8 and -9 activity and sperm motility in infertile males of Li nationality in China.

This study's objectives are to assess the efficacy of detecting apoptotic caspase-3, -8, and -9 in human sperm and plasma using enzyme-linked immunosorbent assays (ELISA), and to compare these levels between fertile and infertile patient groups of Li nationality in China. This study offers a non-invasive, alternative strategy to analyzing sperm parameters in infertile males. Fifty-six infertile males were investigated; asthenospermia (n = 19), oligoasthenoteratozoospermia (n = 20), azoospermia (n = 17) compared with 20 healthy fertile controls.

The cytochrome P450 2D6*10 genetic polymorphism alters postoperative analgesia.

The present study was aimed to investigate the effects of the cytochrome P450 (CYP) 2D6*10 genetic polymorphism on postoperative patient-controlled morphine usage. A total of 114 patients were selected, and 102 patients completed the study. Polymerase chain reaction-based restriction fragment length polymorphism (PCR-RFLP) was used to determine the CYP2D6*10 genotype, and patients were categorized into three groups according to CYP2D6 genotype: heterozygous (m/w), wild-type homozygous (w/w), and mutant homozygous (m/m).
