[Objective] Using gene chip to detect the influence on gene expression due to replicate Heart-Qi Deficiency Syndrome on Wistar Rat caused by complex factor including slimming, forced swimming and large dosage of propanolol. [Methods] Every animal in experiment group took food according to 5g/100g body weight, and was forced to swim by taking weight according to its 5% body weight until sank beyond 10 seconds. From 17th day ig propanolol 24mg/Kg and lasted for 4 days. At 21st day we took out hearts and picked up general DNA to prepare probe, then cross with gene chip. [Results] Compared with control group, expression of gene NM-017329,NM-016997 and NM-030850 showed down regulation obviously, expression of gene NM-031345 and NM-024349 showed up-regulation significantly. [Conclusion] Repression of immunological function and damage of vascular endothelium may be the main mechanism resulting in Heart-Qi Deficiency Syndrome.

Functional dizziness is one of the most frequent functional disorders in adult patients.The termfunctional dizziness is not a nosological entity,but comprises several diagnoses.This study is aim to summarize the typical symptoms of functional dizziness and signs and symptoms of non-functional dizziness.
