在这段代码中，可以使用 react-i18next 来对 message 进行文字转换。具体操作如下：

1. 首先，在组件中引入 react-i18next 库。

2. 在组件中使用 useTranslation hook 来获取 t 函数，用于进行文字转换。

3. 在 rules 对象中的每个 message 属性中，使用 t 函数对需要转换的文字进行包裹。例如：

message: t("First Name is required")

完整代码如下：

import { useTranslation } from "react-i18next";

const { t } = useTranslation();

export const rules: Rules = {
  FirstName: [
    {
      type: "string",
      required: true,
      message: t("First Name is required"),
      validator(rule, value, callback, source, options) {
        const firstNameValue = Object.keys(source).find(
          (k) => k.indexOf("FirstName") >= 0
        );
        if (firstNameValue) {
          source["FirstName"] = source[firstNameValue];
        }
        callback();
      },
    },
    { pattern: /^[a-z\s]{1,25}$/i, message: t("Invalid First Name") },
  ],
  LastName: [
    {
      type: "string",
      required: true,
      message: t("Last Name is required"),
      validator(rule, value, callback, source, options) {
        const firstNameValue = Object.keys(source).find(
          (k) => k.indexOf("LastName") >= 0
        );
        if (firstNameValue) {
          source["LastName"] = source[firstNameValue];
        }
        callback();
      },
    },
    { pattern: /^[a-z\s]{1,25}$/i, message: t("Invalid Last Name") },
  ],
  MiddleName: [{ pattern: /^[a-z\s]{1,25}$/i, message: t("Invalid Middle Name") }],
  BirthDate: [
    {
      type: "string",
      validator(rule, value, callback, source, options) {
        if (!value) {
          return callback(t("Birth Date is required"));
        }
        const date = parse(value, "mm/dd/yyyy", new Date());
        const age = differenceInYears(new Date(), date);
        if (age < 22) return callback(t("Patients must be over 22 years old"));
        callback();
      },
    },
  ],
  Gender: {
    type: "enum",
    required: true,
    message: t("Gender is required"),
    enum: ["male", "female", ""],
  },
  MRN: [
    { required: true, pattern: /^[a-z0-9\-]{1,50}$/i, message: t("MRN is required") },
  ],
};
