Post-stroke shoulder-hand syndrome of phlegm-stasis obstruction treated with the combined therapy of eye acupuncture, Tengliao and rehabilitation training: a multi-central randomized controlled trial / 中国针灸

OBJECTIVE@#To assess the efficacy on relieving pain and improving the range of motion of shoulder joint in post-stroke shoulder-hand syndrome of phlegm-stasis obstruction in treatment of the combined therapy of eye acupuncture, Tengliao (Chinese herbal warm dressing technique) and rehabilitation training (eye acupuncture + Tengliao + rehabilitation) as compared with the combined treatment of Tengliao and rehabilitation training (Tengliao + rehabilitation) and the simple rehabilitation training (rehabilitation).@*METHODS@#A total of 356 patients with post-stroke shoulder-hand syndrome of phlegm-stasis obstruction were randomized into an eye acupuncture + Tengliao + rehabilitation group (group A, 122 cases, 2 cases dropped off), a Tengliao + rehabilitation group (group B, 120 cases, 3 cases dropped off) and a rehabilitation group (group C, 114 cases, 1 case dropped off). In the group C, the basic treatment was combined with routine rehabilitation training. In the group B, on the base of the treatment as the group C, Tengliao was exerted. A medical bag composed of over 20 Chinese herbal materials was heated and dressed at the affected area, 30 min each time, 5 times weekly. In the group A, besides the treatment as the group B, eye acupuncture was applied to heart region, kidney region, upper jiao region and lower jiao region, 30 min each time, 5 times weekly. The treatment lasted 28 days in all of three groups. Separately, before treatment, in 7, 14, 21 and 28 days of treatment, as well as in 14 days after treatment of follow-up, the score of visual analogue scale (VAS) for pain, the score of guides to evaluation of permanent impairment (GEPI) and the score of National Institutes of Health stroke scale (NIHSS) were observed in each group.@*RESULTS@#The scores of VAS, GEPI and NIHSS were all improved with the treatment lasting in the three groups (P<0.000 1). In 7, 14, 21 and 28 days of treatment and in follow-up as well, VAS scores in the group A were all lower than the group C (P<0.05). After 14 days of treatment, GEPI score showed increasing trend, while NIHSS score showed decreasing trend in the group A compared with the group B. Before treatment, GEPI score was lower and NIHSS score was higher in the group A compared with the group C (P<0.05). It was suggested that the illness was slightly serious in the group A. After propensity score matching, in 14, 21 and 28 days as well as in follow-up, GEPI scores in the group A were higher than the group C respectively (P<0.05). Regarding NIHSS score at each time point, the difference had no statistical significance between the group A and the group C (P>0.05).@*CONCLUSION@#The combined therapy of eye acupuncture, Tengliao and rehabilitation training obtains a better efficacy on post-stroke shoulder-hand syndrome of phlegm-stasis obstruction as compared with rehabilitation training.

Comparison of structural characteristics and bioactivities of polysaccharides from loquat leaves prepared by different drying techniques.

In the present study, freeze drying, hot-air drying, vacuum drying, and microwave drying at the microwave powers of 400, 600, and 800 W, respectively, were utilized to dry loquat leaves for evaluating the effects of different drying techniques on the physicochemical structures and bioactivities of polysaccharides extracted from loquat leaves (LLPs). Results demonstrated that the physicochemical structures and bioactivities of LLPs significantly affected by different drying techniques. The degrees of esterification, molar ratios of constituent monosaccharides, contents of uronic acids, apparent viscosities, and molecular weights of LLPs were varied by different drying techniques. Additionally, LLPs, particularly LLP-M4 which extracted from loquat leaves prepared by microwave drying at the power of 400 W, exerted remarkable in vitro binding capacities, strong inhibitory effects on α-amylase and α-glucosidase, and obvious antioxidant activities. Results indicated that the microwave drying could be an efficient drying technique before extraction of bioactive LLPs, and LLPs had great potential applications in the functional food and pharmaceutical industries.

Inhibitory effect of ginsenoside-Rg3 on lung metastasis of mouse melanoma transfected with ribonuclease inhibitor / 中华肿瘤杂志

<p><b>OBJECTIVE</b>To investigate the effect of ginsenoside-Rg3 on lung metastasis of ribonuclease inhibitor (RI) gene-transfected mouse B16 melanoma.</p><p><b>METHODS</b>C57BL/6 mice were iv injected with parental or RI-transfected B16 melanoma cells. Lung metastasis was assessed by the number of surface tumor nodules. Mice were divided into 6 groups. Group I, II and III of mice were given parental, mock-transfected and RI-transfected B16 melanoma cells, respectively while in group IV, V and VI, Rg3 (1.5 mg/kg, iv q.o.d. x 10) was given to mice bearing parental, mock-transfected and RI-transfected B16 melanoma, respectively. Micovessel density (MVD) of the lung metastatic tumor was assessed by immunohistochemical staining of factor VIII-R expression.</p><p><b>RESULTS</b>The number of tumor nodules was significantly decreased in mice injected with RI-transfected B16 melanoma (Gp III, compared to Gp I and II). Rg3 treatment per se could also decrease the number of lung tumor nodules but to a lesser extent (Gp IV and V compared to Gp III). However, Rg3 synergized with RI transfection resulting in most significant inhibition of lung metastasis (Gp VI). Mice in Gp I and II died within 26 days of the experiment, whereas all the mice in Gp VI were alive during the observation period of one and one half month. MVD was significantly decreased in the lung tumor nodules in mice injected with RI-transfected B16 melanoma. It was further decreased when additional Rg3 was given (Gp VI).</p><p><b>CONCLUSION</b>Transfection of ribonuclease inhibitor gene significantly reduces the metastatic potential of B16 melanoma. Ginsenoside-Rg3 has a synergistic effect.</p>
