Results： Subacute onset occurred in three cases of patients after they have taken the oral hypoglycemic health product for several months and the disease was progressively aggravated, in which limb peripheral-type sensory and motor deficits were as the main performance.

Among them, one case of patient with respiratory dififculty could not be recovered after immunoglobulin and glucocorticoid therapy and the others were relieved after glucocorticoid therapy.Conclusion： The efifcacy of immunoglobulin and glucocorticoid therapy on the peripheral neuropathy with heavy metals （mercury and arsenic） poisoning are varied and great attention should be paid to the history of the use of medicines and health products in patients.
