简要总结
The goal of this observational study is to test the alterations of gut microbiota composition among women of reproductive age with elevated homocysteine levels. The main question it aims to answer is:
• the relationship between gut microbiota composition and recurrent abortion. Participants will provide their stool samples to be detected the composition of gut microbiota. .
Researchers will compare women of reproductive age with normal homocysteine levels to see if any bacteria were involved in recurrent miscarriages.

结局指标
主要结局
homocysteine levels
时间窗: The first day of the trail
Binding or dimer homocysteine (oxidized form) is reduced to free homocysteine, and then it is catalysed by cysteine β-synthetase (CBS) to react with serine to form cysteine sulfuric acid. Cysteine is then broken down by cysteine β-lyase (CBL) to form homocysteine, pyruvate, and ammonia. Pyruvate is then converted to lactate using lactate dehydrogenase (LDH), where nicotinamide adenine dinucleotide (NADH) is used as a coenzyme. The ratio of NADH to NAD\* is directly proportional to the concentration of homocysteine (△ A340 nm).
