您可以使用正则表达式来匹配两个下划线之间的字符串，并用<b>标签包裹它。您可以使用字符串对象的replace方法来执行此操作。例如，您可以修改您的代码如下：
const dbString = "_这是来自数据库的字符串_。确保这是来自数据库的格式。";
const formattedString = dbString.replace(/_(.*?)_/g, "<b>$1</b>");
return <div dangerouslySetInnerHTML={{ __html: formattedString }} />;
英文:
You can use a regular expression to match the string between two underscores, and wrap it with a <b> tag. You can use the replace method of the string object to perform this operation. For example, you can modify your code like this:
const dbString = "_This is string from DB_. Make sure this is format from DB";
const formattedString = dbString.replace(/_(.*?)_/g, "<b>$1</b>");
return <div dangerouslySetInnerHTML={{ __html: formattedString }} />;
