Objective: To observe the effect of muscle regions of meridians warm needling method plus pricking Jing-Well points for blood-letting in improving nail fold microcirculation in the patients with shoulder-hand syndrome (SHS) after stroke, and the effects on hemorrheology, calcitonin gene-related peptide (CGRP) and serum substance P (SP). Methods: A total of 72 patients were randomized into an observation group and a control group by the random number table method, with 36 cases in each group. The control group was treated with physical rehabilitation training, and the observation group was treated with additional muscle regions of meridians warm needling method plus pricking Jing-Well points for blood-letting treatment. The treatment course lasted for 4 weeks. After treatment, the clinical efficacy of the two groups was compared. The changes in shoulder-hand syndrome scale (SHSS), simplified Fugl-Meyer assessment-upper extremity (FMA-UE), visual analog scale (VAS), activities of daily living (ADL), traditional Chinese medicine (TCM) syndrome score, nail fold microcirculation hemorheology indictors [whole blood viscosity (high-shear, low-shear), hematocrit, erythrocyte sedimentation rate (ESR)], CGRP and SP levels were observed. Results: The total effective rate in the observation group was 86.1％, higher than 63.9％ in the control group (P<0.05). The overall curative effect in the observation group was better than that in the control group (P<0.05). After treatment, the scores of pain sensation, edema, external turn and rotation of the arm in SHSS, and the total score were significantly decreased in both groups (all P<0.05), and each score in the observation group was lower than that in the control group (all P<0.05). After treatment, the scores of VAS and TCM syndrome in both groups decreased significantly (all P<0.05), and the scores of FMA-UE and ADL increased significantly (all P<0.05). The scores of VAS and TCM syndrome in the observation group were lower than those in the control group (both P<0.05), and the scores of FMA-UE and ADL were higher than those in the control group (both P<0.05). After treatment, the whole blood viscosity (high-shear and low-shear) and hematocrit in both groups decreased obviously (all P<0.05), and ESR increased obviously (both P<0.05), and the whole blood viscosity (high-shear and low-shear) and hematocrit in the observation group were lower than those in the control group (all P<0.05), and ESR was higher than that in the control group (P<0.05). After treatment, the peritubular state, loop shape, blood flow and total score of nail fold microcirculation in both groups decreased significantly (all P<0.05), and each score in the observation group was lower than that in the control group (all P<0.05). After treatment, SP in both groups decreased obviously (both P<0.05), CGRP increased obviously (both P<0.05), and SP in the observation group was lower than that in the control group (P<0.05), CGRP was higher than that in the control group (P<0.05). Conclusion: Compared with conventional physical rehabilitation training, muscle regions of meridians warm needling method plus pricking Jing-Well points for blood-letting treatment can significantly reduce the clinical symptoms of SHS, promote the recovery of physical functions, improve the nail fold microcirculation and hemorrheology indictors, and regulate the serum cytokine levels such as CGRP and SP.

Background Experimental study showed that heparanase (HPA)is overexpressed in choroidal neovascularization,suggesting that it may play a role in the pathogenesis of angiogenesis.To certify HPA inhibitor suppress the formation and development of new blood vessel has an important significance for the treatment of choroidal neovascularization.Objective The aim of this study was to investigate the effect of HPA inhibitor on the proliferation of human umbilical vein vascular endothelial cell (UVEC) and the expression of HPA.Methods Hunan UVEC was primarily cultured and passaged and the third generation cells were used in the experiment.Phosphomannopentaose sulfate (PI-88) solution,a HPA inhibitor,was prepared with endothelial cell medium and the end concentrations were 400.00,200.00,100.00,50.00,25.00,12.50,6.25 mg/L respectively.The cells were treated with PI-88 solutions for 24,48 and 72 hours.The growth and proliferation of human UVEC were analyzed using MTT colorimetric assay at absorbance 570 nm.The expression of HPA in the cells was detected by immunochemistry in 48 hours after addition of PI-88.Results Cultured human UVEC showed the fusiform and polygon in shape.The A570 values of human CVEC were significantly different among various concentrations of PI-88 groups (F=2.721,P=0.053 ) and different action time (F=9.656,P =0.002).When PI-88 was administered for 24 hours,the A570 values of human UVEC were insignificantly altered in comparison with the one without PI-88 culture group (P＞0.05 ).However,in 72 hours after experiment,the A570 values were significantly declined as the PI-88 concentration was ＞50.00 mg/L ( P＜0.05 ).When PI-88 was administered for 48 and 72 hours,the A570 values of human UVEC were significantly higher than those of 24 hours in ＜50.00 mg/L groups (P＜0.01 ),but no statistical differences were seen in ＞100.00 mg/L groups among various time points (P＞0.05 ).HPA was intently expressed in the cytoplasm of human UVEC.However,at 48 hours after addition of ＞25.00 mg/L PI-88,the HPA expression was obviously weaker.Conclusions PI-88 can suppress the growth and proliferation of human UVEC at the dose-and time-dependent manner by downregulating the expression of HPA in the cells.
