Objective Try to discover the safe and effective inhibitors of lymphangiogenesis. Methods Lymphatic endotheial cells from pig thoracic duct were isolated and cultured. The observation of specimens by LM and EM was made. The control group, endostatin and PF-4 experimental groups were set. Methods of the scraped line and MTT were used to examine their inhibitive effect on the lymphangiogenesis. Results The P value is

Objective To observe the effects of CoC12 treatment on the expression of Hypoxia-inducible factor-1(HIF-1α) in mice hippocampus at different time point.Methods Balb/c mice were injected with CoCl2 and the change of HIF-1 α was detected by western blot and immunofluorescence and confocal laser scanning microscope at different time point(0h,1h,2h,3h,4h,5h and 6h) after injection.Results The relative protein level of HIF-1α was 0.135 ±0.01,0.572 ±0.01,0.595 ±0.03,1.09 ±0.03,1.30 +0.04,1.275 ±0.03,0.947 ±0.03respectively at different time point after the injection.The HIF-1α protein level reached its peak value at 4 h and decreased at 5h and 6h.Fluorescence intensity of HIF-1α was 13.33 ± 3.42,30.95 ± 7.86,46.50 ± 9.65,61.50± 10.02,88.30 + 15.69,71.39 ± 11.28,67.41 ± 10.78 respectively at different time point after the injection.The HIF-1α fluorescence intensity also reached its peak value at 4 h and decreased at 5h and 6h.Conclusion Time dependent HIF-1α accumulation was in close correlation with the CoCl2.

Aim To investigate the influence of intranasal delivery of calcitonin gene-related peptide(CGRP)on cerebral blood supply and expression of vascular endothelial growth factor(VEGF)following experimental subarachnoid hemorrhage(SAH).Methods Wistar rats were divided into normal control group,SAH group,intranasal normal saline(NS)+SAH group and intranasal CGRP+SAH group.SAH models were produced by double injection of autologous arterial blood into cisterna magna.CGRP and NS were given by intranasal perfusion.Dynamic observations of regional cerebral blood flow(rCBF)of cerebral cortex were made using a laser Doppler flowmeter probe.On the third day after the second cisternal injection,the expression of VEGF protein in cerebral cortex was observed by immunofluorescence method combined with laser confocal microscopic observation.Results Anatomic observation revealed that SAH models were successfully manufactured.In SAH and intranasal NS+SAH groups,a drastic and persistent drop in rCBF was noted during the observed periods.The decrease of rCBF in intranasal CGRP+SAH group was slighter as compared with that in SAH and intranasal NS+SAH groups.In SAH and intranasal NS+SAH groups,increased expression of VEGF protein in cerebral cortex was observed on the third day after second cisternal injection as compared with that in normal control group.The expression of VEGF in intranasal CGRP+SAH group was more obvious than that in intranasal NS+SAH group.Conclusion Intranasal delivery of CGRP improves cerebral blood supply and promotes angiogenesis by enhancing the expression of VEGF after SAH.

ObjectiveTo investigate the clinical effect of Shipiyin combined with diosmin in the treatment of lymphedema with spleen Yang deficiency syndrome（SYDS）after modified radical mastectomy and the specific effect on the function of the affected limb. MethodEighty-two patients with lymphedema with SYDS after modified radical mastectomy from outpatient and inpatient department of breast department and oncology department of the First Affiliated Hospital of Hunan University of Chinese Medicine were randomly divided into an observation group（41 cases） and a control group（41 cases）. The control group was given diosmin tablets（0.9 g per time， two times per day）on the basis of conventional treatment，and the observation group was given Shipiyin（one dose per day）on the basis of the control group. The course of treatment was 14 days. The clinical symptoms were observed and the limb circumference，traditional Chinese medicine（TCM） syndrome score，functional assessment of cancer therapy-breast cancer（FACT-B） score，disability of arm， shoulder and hand questionnaire（DASH） score，and joint range of motion were measured to analyze the TCM syndrome therapeutic effect and clinical efficacy. ResultAfter 14 days of treatment， the total effective rate of the observation group was 85.37% （35/41） and that of the control group was 63.41% （26/41） in the TCM symptoms， showing a statistically significant difference （Z=-2.212， P<0.05）. In terms of the clinical efficacy， the total effective rate in the observation group was 82.93% （34/41） and that in the control group was 75.61% （31/41）， indicating a statistically significant difference （Z=-2.061， P<0.05）. Compared with the situations before treatment， the scores of clinical symptoms such as the swelling of the upper limb， pain， sense of heaviness， stuffiness， fatigue， fullness， tightness， and skin keratosis and pruritus in the two groups were significantly lowered （P<0.01） after treatment. Compared with the control group， the observation group could better improve the swelling and fullness（P<0.01），as well as the feeling of pain，heaviness，stuffiness，fatigue，tightness，skin keratosis and pruritus （P<0.05）of the upper limbs of patients. The affected limb circumference， TCM syndrome score， and DASH score decreased significantly， while the FACT-B score and upper limb joint range of motion increased significantly in the two groups after treatment （P<0.01）. Compared with the control group， the observation group showed significantly reduced limb circumference at 10 cm proximal to the elbow striae， lowered TCM syndrome score， elevated FACT-B score（P<0.05）， decreased DASH score and improved range of motion of the upper limb joint （P<0.01） after treatment. ConclusionShipiyin combined with diosmin has better clinical efficacy in the treatment of lymphedema with SYDS after modified radical mastectomy than diosmin alone，which can better improve the clinical symptoms，signs，quality of life and limb functional activity of patients. This provides a new clinical program for the treatment of lymphedema after breast cancer surgery with integrated Chinese and western medicine.
