Immune stimulation and two-way adjustment: intravascular laser irradiation can activate the immune system required for the activity of enzymes, the number of T lymphocytes and CD4 \ CD8 ratio increased, regulate immune function, so that the imbalance of CD4 \ CD8 values tend to normal, spontaneous rosette formation increase in the number of lymphocyte transformation rate, the increase in lymphocyte and macrophage activity, and normalization of human immune globulin, complement, resulting in a variety of immune system regulation. You can also improve erythrocyte immune system function, promote red blood cell enzymes, receptors, surface charge redistribution, increase red blood cell deformability and effectively regulate the erythrocyte C3b receptor function and number, so that the blood younger, increase immunity.
Mental stress: the long-term mental stress, anger, worry, vicious environmental stimuli (such as noise), can lead to high blood pressure. Nervous career high incidence; Occupation: work stress, attention is highly concentrated with little physical activity, occupation, significantly higher incidence of hypertension. Mental high incidence of manual workers; drinking: alcohol can cause high blood pressure, increased blood pressure, damage to cardiovascular and cerebrovascular; smoking. Symptoms of high blood pressure and hazards. The new study shows that high blood pressure may damage the organs: the one held in Washington, the American Heart Association High Blood Pressure Research Conference, even if the blood pressure is a slight increase can also cause kidney and heart damage. Actually, the self inspection is the primary step of quality inspection of  laser pointer .
Harbinger of the so-called hypertension, is critical (. Borderline bring), high blood pressure, is made by the American Heart Association earlier this year when the hypertension classification, any person's systolic blood pressure (the highest number) for more than 120 or 120, or diastolic pressure (lowest number) for more than 80 or 80, you can consider a higher chance of such patients suffering from heart attack or stroke - hypertension or high blood pressure aura, it is estimated that about 23% of the population Hypertension aura, in addition to the 25% or more has been identified as having hypertension. It will enhance the result of the quality inspection of  laser pointer .
The French the Meng Boli city of Lapeyronie Hospital researcher Pierre Fesler say, in this study, a total of 108 hypertension aura "- high blood pressure patients, including 265 with normal blood pressure to participate. Track inspection, he found a trend, that is, when the possibility of increased blood pressure, kidney and heart hurt also increase, but the reality is that: high blood pressure in the optimal (less than 120/80) 7 percent, hurt certain organs; normal blood pressure (below 130/85), 13% of some organs are hurt; in the high normal blood pressure (130-139/85-89), 23 % of organs has been hurt. He spent six months tracking the 28 patients with the condition.
