Intravascular low energy laser therapy (ILELT) was put forward for cardiocirculatory diseases in USA in 1982, was
popular in Russia in 1980s, and then in China in 1990s. The therapeutic effects of ILELT and drugs in comparison with
drugs only on Chinese patients and their blood parameters were analyzed with meta-analyses and reported as (OR,
95%CI) for patient improvement and (WMD, 95% CI) for blood parameter improvement, where 95%CI, OR and WMD
denoted 95% confidence intervals, odds ratio and weighted mean difference, respectively. It was found that the patients
of cerebral infarction (2.39, 2.09~2.74) and cerebrovascular diseases (2.97, 1.69~2.53) were cured, respectively, (P <
0.01), and the symptom improvement of patients of cerebral infarction, cerebrovascular diseases and diabetes were
significant (3.13, 2.79~3.51), (4.92, 3.39~7.14) , and (3.80, 2.79~5.18), and mild (3.66, 3.15~4.24), (4.95, 2.77~8.84),
and (7.11, 4.54~11.13), respectively, (P < 0.01). It was also found that the blood parameters such as cholesterol (-0.78,
-1.32~-0.24), total cholesterol (-1.08, -1.80~-0.36), low density lipoprotein cholesterol (-0.6, -1.01~-0.19), triacylglycerol
(0.63, -0.83~-0.42), high density lipoprotein (0.34, 0.10~0.59), erythrocyte aggregation index (-0.24, -0.27~-0.21),
erythrocyte Sedimentation Rate (-4.57, -7.26~-1.89), fibrinogen (-0.76, -1.31~-0.21), whole blood contrast viscosity
(-0.40, -0.69~-0.12), low cut blood viscosity (-1.2, -1.93~-0.48), high cut blood viscosity (-0.62, -0.92~-0.32), whole
blood viscosity(-1.2, -1.85~-0.54) and plasma blood contrast viscosity(-0.07, -0.12~-0.03) were found improved (P <
0.05). It is concluded that the patients of cerebral infarction, cerebrovascular diseases and diabetes might be improved
with ILELT, which might be mediated by blood parameter improvement.
