Hyperlipidemia is an elevation of lipids in the bloodstream, These lipids include cholesterol, cholesterol esters, estersphos- Pholipids and triglycerides (TG). Numberous studies have suggested That hyperlipidemia is closely linked to cardiovascular disease. Lipid Lowering has been shown to be effective in preventing primary and Recurrent cardiovascular events and to save life. Statins almost Exclusively used for this purpose meanwhile became one of the most widely prescribed families of drugs world-wide. Statins are possibly the most effective drugs for the prevention and treatment of hypercholesterolaeia and coronary heart disease (CHD). They are generally well tolerated, however, they do cause some unusual side-effects with potentially severe consequences, most prominently myopathy or rhabdomyolysis and polyneuropathy. As a natural therapy as show in chapter 3.5, ILILT has been used to rehabilitate hyperlipidemia.

Zhang X et al. (2003) have treated 38 patient with hyperlipi- demia with low intensity He-Ne laser irradiation (LHNL) at 1.5 mW for 30 min each time, which were done once a day and five days each session for two sessions, and found total cholesterol (TC), TG and low density lipoprotein cholesterol( LDL-C) levels deceased 23.7%, 36.2% and 20.2%, respectively.

Chi et al (2005) have randomly divided 30 patients with hypet- Lipidemia into two groups, 15 drugs group, 15 in ILILT group, And then treated ILILT group with low intensity GaInP/AIGaInp Diode laser irradiation at 650nm(LGAL) at 5mW for 45 min each Time, which was done once a day and seven times each session for Tow sessions between which there was five days for rest, and fond ILILT induced significant decrease in TC, but the decrease was less Than drugs induced one. Chi et al. (2005) also found the aminotrans- Ferases level decreased.

It has been found that acupuncture induced blood lipid decrease Was mainly mediated by stomach meridian of foot yang-ming. Nasal Stomach meridian of foot yang-ming might also mediate ILILT Induced decrease of blood lipid according to meridian mediated ILILT hypothesis (MIH) which was put forward in chapter 3.3 Du meridian and liver meridian of foot jue-yin are coupled with each other at bai-hui acupoint (GV 20) (Fig.8) so that ILILT induced decrease of aminotransferases might be mediated by intranasal du meridian according to MIH.

In addition to ILILT, the laser acupuncture of low intensity laser Irradiation(LIL) of ILILT and the akin-contact electric acupuncture of low frequency pulse might be used to effectively treat hyperlipidemia. Li X W.(200) has treated 68 patients with hyperlipidemia with LHNL on acupoints for 5 min each acupoints each time, which were Done once a day 30 days each acupoints each time, which were Done once a day 30 days each session for 6 sessions between which There 3 days for rest, and found TG level deceased significantly, and The symptom improvenment of 48 (70.5%), 18 (28.1%) and 2(1.4%) Patients were significant, mild and none, respectively, after only one Session. In this treatment, the main acupoints are sanyinjiao(SP6) (Fig.5) and zusanli(ST36) (Fig.6), the adjunct acupoints are neiguan (PC6) (Fig.6), tachong(LR3) (Fig.6), hegu(114) (Fig.5) And fenglong (ST40) (Fig.6).
