This study sorted out the records of blood-pricking therapy in ancient and modern medical literature, and clarified the origin and development of blood-pricking school. The main stages of the school development included origin and germination stage, the theoretical development stage, the experience accumulation stage, the theoretical innovation and characteristic formation stage, the continuous improvement and maturity stage and the unprecedented development stage. The main academic thoughts included the idea of resolutely eliminating the blood-excess, the idea of completely expelling evil, the idea of simultaneous application of acupuncture-moxibustion and medication and the idea of focusing the use of jing-well point. This school has a far-reaching impact on modern clinical practice.

<p><b>OBJECTIVE</b>To observe the therapeutic angiogenesis effect of naotai recipe (NR) on local ischemia/reperfusion (I/R) injury of rats by observing signaling pathway of hypoxia-inducible factor-lα (HIF-1α) and vascular endothelial growth factor (VEGF).</p><p><b>METHODS</b>Totally 120 Sprague-Dawley (SD) rats were randomly divided into 4 groups, namely, the normal control group (n =12), the sham-operation group (n =12), the I/R model group (n =48), and the NR group (n =48). Cerebral I/R injury models were established using thread suture method. Rats in the I/R model group and the NR group were sub-divided into 4 sub-groups according to the 1st, 3rd, 5th, and 7th I/R day (n =12). The phenomenon of neovasculization was observed by immunofluorescence staining. The protein and mRNA expression levels of HIF-la, VEGF-A, and VEGFR II receptor were detected by RT-PCR.</p><p><b>RESULTS</b>There were a large amount of labels for neovasculization in the ischemic area of the NR group. Double-immunofluorescence labeling [vWF (red) and BrdU (green)] was observed in the NR group. Compared with the model group, the HIF-1α protein expression was obviously enhanced on the 1 st day of I/R (P <0.01), and the VEGF protein expression started to enhance on the 3rd day in the NR group (P <0.01). The VEGFR protein expression level was the highest in the NR group on the 5th day of I/R (P <0.01). The protein expression of VEGF and HIF-1α started to decrease on the 7th day of I/R.</p><p><b>CONCLUSION</b>NR could strengthen angiogenesis after I/R by elevating the expression of HIF-lα and activating HIF-lα/VEGF signaling pathway.</p>
