The growth and metastasis of tumor relies on oxygen and nutrients provided by neonatal blood vessel. When no angiogenesis, the tumor growth will be obviously inhibited. At present, anti-tumor angiogenesis strategies are increasingly becoming a focus of attention and study at home and abroad. However,because of the complexity of the antiangiogenesis, the clinical effects of antiangiogenesis alone is not so satisfied, while this is reversed when combined with radiotherapy.

Objective To observe the clinical efficacy of point injection of spleen polypeptides in the treat-ment of acute exacerbation of chronic obstructive pulmonary disease(AECOPD).Methods Totally 60 patients with AECOPD were randomly divided into the observation group and the control group,30 cases in each group.Based on conventional treatment,the observation group was treated by point injection of spleen polypeptides,4ml for each time, 1 time a day;and the control group was given equivalent volume of spleen polypeptides by intramuscular injection.The treatment lasted two weeks.The clinical efficacy,PCT,inflammatory and ADRs of patients in the two groups were observed.Results In 7 days of treatment,the clinical efficacy was 87% in the observation group,which was better than 60% of the control group (χ2 =5.45,P=0.019).PCT,interleukin-6(IL-6),interleukin-8(IL-8),tumor necrosis factor-α(TNF -α)of the observation group and the control group were (1.84 ±1.48)ng/mL and (2.21 ±1.75)ng/mL,(32.54 ±6.62)ng/L and (38.94 ±5.69)ng/L,(31.51 ±6.03)ng/L and (36.75 ± 7.95)ng/L,(45.90 ±4.40)ng/L and (51.53 ±2.21)ng/L respectively,which were lower than before treatment (t=12.76 and 15.25,13.23 and -8.42,-10.43 and 5.78,25.04 and 26.95,all P<0.01),which of the obser-vation group were lower than the control group(t=-2.84,4.01,-2.74,-6.27,all P<0.01).After treatment, PCT,IL-6,IL-8,TNF-αof the observation group and the control group were (1.05 ±0.74)ng/mL and (1.38 ± 0.87)ng/mL,(26.89 ±3.57)ng/L and (32.44 ±5.96)ng/L,(21.40 ±3.41)ng/L and (27.71 ±5.50)ng/L, (32.29 ±2.40)ng/L and (39.77 ±2.57)ng/L respectively,which were lower than before treatment(t=22.40 and 22.44,23.10 and -11.96,21.40 and 12.66,48.94 and 38.81,all P<0.01),which of the observation group were lower than the control group(t=-4.09,-4.26,-5.29,-11.68,all P<0.01).No obvious side effect was found in the two groups in the treatment and followed-up period.Conclusion Point injection of spleen polypeptides can effectively reduce the inflammatory response in patients with AECOPD,improve clinical outcomes,shorten course of treatment,has better clinical value.

The distribution of substance P-positive structure was studied in the human and rat spinal cord using immunohistochemical technique. The results showed that a very dense network of substance P-positive fibers was found in the spinal cord in laminae Ⅰ-Ⅲ, in Lissauer's fasciculus and a rather dense plexus was seen in the area around the central canal. P-positive fibesr were observed in the ventral horns, but they were rare. These positive fibers were stained yellow, brown and dark-brown colour. In addition, substance P-positive neuronal cell bodies and fibers were seen in rat spinal ganglia, and they were smaller cells.
