OBJECTIVETo study the effect of Wu-He Dipsacus asper (WHDA), Traditional Chinese Medicine, injection on mice-aging model induced by D-galactose.

METHODSForty-eight Kunming mice (24 male and 24 female) were randomly divided into control group, model group, positive control group, 7.2 g/kg WHDA group, 3.6 g/kg WHDA group and 1.8 g/kg WHDA group with eight in each group. The model was induced through injecting D-galactose into peritoneal cavity and Morris water maze was used to detect the learning and cognitive ability of mice. The skin hydroxyproline, brain tissue malondialdehyde (MDA), lipofuscin (LP), superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) levels of mice were detected; the IL-2 and IL-6 levels in serum of mice were detected by using double antibody sandwich ELISA method.

RESULTSEach WHDA group was significantly reduced in latency period compared with the model group during Morris water maze test (P < 0.05) and the number of mice in model group through the platform was less than other mice in each group (P < 0.05). The levels of MAD and LP of the control group and each WHDA group were less than model group in the detection of heart, brain tissue oxidation index (SOD, MAD, LP and GSH-Px, P < 0.05). The activity of SOD and GSH-Px in the control group and each WHDA group was significantly higher than that in the model group (P < 0.05). The skin hydroxyproline content of mice which had been injected with D-galactose was significantly lower than that in the control group (P < 0.05) and the skin hydroxyproline content of mice of WHDA group was significantly higher than that in the model group (P < 0.05). The IL-2, IL-6 levels in serum of mice in WHDA group were significantly higher than those in the control group and the model group (P < 0.05) and the IL-2, IL-6 levels in serum of mice in the model group were lower than those in the control group (P < 0.05).

CONCLUSIONThe effective constituents of WHDA have a variety of biological activity which can have a good effect on anti-aging by different ways, improving learning and memory function, eliminating free radicals antioxidant, and enhancing the body immunity and other aspects.

Background Vitronectin is a glycoprotein that has a variety of functions.Its expression was markedly higher in the retina of oxygen induced mice,which was confirmed in our animal model,and also increased in human umbilical vein endothelial cells (人 UVECs) that were cultured in high glucose.However,there was no evidence that showed vitronectin was involved in retinal neovascularization.Objective This study was to observe the influence of vitronectin on cytoskeleton remodeling,cell migration and blood vessel formation in 人 UVECs conditioned by high glucose.Methods 人 UVECs were cultured in high glucose and the expression of vitronectin was knocked down using RNA interference technology.The experiments were divided into the high glucose group (人 UVECs were conditioned with DMEM medium that contained 50 mmol/L glucose),negative interference group (人 UVECs were transfected with control siRNA in advance,and then were conditioned with DMEM medium that contained 50 mmol/L glucose) and positive interference group (HUVEC were transfected with vitronectin siRNA in advance,and then were conditioned with DMEM medium that contained 50 mmol/L glucose).The protein expression of vitronectin was measured by Western blot,and the microfilament cytoskeleton of 人 UVECs was examined by immunofluorescence cytochemical staining followed by fluorescence microscopy.Cell migration ability in a scratch wound assay and blood vessel formation ability in a matrigel assay of 人 UVECs were evaluated.The general differences were analysed by One-Way ANOVA ;further contrasts of the two groups were analysed by the LSD-t test.Results The differences in vitronectin expression of the three groups were not obvious at 0 hour (F=1.064,P＞0.05).After 24 hours,vitronectin expression was highest in the high glucose group,lower in the negative interference group,and the lowest in the positive interference group,and the differences were significant (F =15.519,P＜0.05).After 48 hours,vitronectin expression of the three groups displayed the same pattern,and the differences were also significant (F=37.521,P＜0.05).Immunofluorescence showed that the cytoskeleton structure was most obvious in the high glucose group,moderate in the negative interference group,and was the least obvious in the positive interference group,after both 24 hours and 48 hours.In the scratch wound assay,the cell migration ability of the high glucose group was the highest,lower in the negative interference group,and the lowest in the positive interference group after 24 hours,and the differences were significant (F=90.685,P＜0.05).After 48 hours,the cell migration abilities of the three groups displayed the same pattern,and the differences were also significant (F=67.880,P＜0.05).In the matrigel assay,after 6 hours,the number of blood vessels formed in the high glucose group was more than that in the negative interference group,and the least amount was found in the positive interference group.The differences among of them were significant (F =86.653,P＜0.05).The number of blood vessel formed in the positive interference group was also the lowest after 12 hours,and the differences were also significant (F=18.992,P＜0.05).Conclusions Vitronectin can bring about cytoskeleton remodeling,increase in cell migration,and enhancement of blood vessel formation in 人 UVECs conditioned in high glucose.It may be one of the important influence factors of diabetic retinopathy.

Objective: To observe the clinical effect of Zheng's Jin Gou Diao Yu (gold-hook-fishing) acupuncture method versus ordinary acupuncture on superficial fascia for treating neck type cervical spondylopathy in Kyrgyz. Methods:A total of 64 Kyrgyz patients conforming to the diagnostic criteria of neck type cervical spondylopathy were included. The patients were randomized into a Zheng's Jin Gou Diao Yu (gold-hook-fishing) acupuncture group and a conventional acupuncture group, with 32 cases in each group. Patients in the Zheng's Jin Gou Diao Yu (gold-hook-fishing) acupuncture group were treated with Zheng's Jin Gou Diao Yu (gold-hook-fishing) acupuncture method to stimulate the superficial fascia, the stimulation sites were primarily located at bilateral sides of the cervical vertebra as well as the trigger points in shoulder-neck region; patients in the conventional acupuncture group were punctured at the same acupoints, with twirling reducing method, and the depth of insertion was determined by the treated region. Patients in both groups received treatment every day for a succession of 5 d as a course, with a 2-day interval between 2 courses, and the whole treatment lasted for 3 courses. After 3 courses of treatment, the McGill pain questionnaire (MPQ) and neck disability index (NDI) were measured to compare the clinical effect between the two groups. Results: After treatment, scores of MPQ and NDI scale dropped when compared with those before treatment, and the differences showed statistical significance (allP<0.05); scores of MPQ and NDI in the Jin Gou Diao Yu (gold-hook-fishing) acupuncture group were substantially lower than those in the conventional acupuncture group, and the differences showed statistical significance (allP<0.05). The total effective rate was 96.9％ in the Jin Gou Diao Yu (gold-hook-fishing) acupuncture group and the cured rate was 78.1％, which were higher than 81.3％ and 40.6％ in the conventional acupuncture group, and the differences showed statistical significance (bothP<0.05). Conclusion: Zheng's Jin Gou Diao Yu (gold-hook-fishing) acupuncture method by stimulating superficial fascia to treat cervical spondylopathy in Kyrgyz can produce a better clinical effect than conventional acupuncture treatment, and is effective in improving pain and stiffness in patients, and thus is worth clinical popularization.
