ABSTRACT
Objective: To find out the relation factors of hyperuricemia in cadres. Methods: The cadres who had health check on 2008 were analyzed. Results: The rate hyperuricemia in cadres of Zhuhai city was 35.42%. Conclusion: The rate of hyperuricemia in cadres is increasing by ages. It has the relations with sexual distinction, overweight or obesity, abnormal triglyceride and high purine-food.
ABSTRACT
BACKGROUND: Epidermal stem cells (ESCs) are of importance in the wound repair. Explaining the mechanism thatChinese herb speeds up the regeneration of injured skin from the angle of inducing stem cells deserves to be studied. OBJECTIVE: To observe the effect of Yuhong ointment on the proliferation and differentiation of ESCs during ratwound healing. DESIGN: A randomized controlled animal experiment. SETTING: Department of Pharmacology, Wangjing Hospital, China Academy of Chinese Medical Sciences. MATERIALS: This study was carried out in the Department of Pharmacology, Wangjing Hospital, China Academy ofChinese Medical Sciences between July and September 2006. Totally 114 healthy Wistar male adult rats, of cleangrade, weighing 180-210 g, were provided by the Laboratory Animal Center, Institute for Basic Theory of TraditionalChinese Medicine, China Academy of Chinese Medical Sciences were enrolled in this study. The processing ofanimals corresponded to the standard of Animal Ethics. Yuhong ointment was purchased from the PharmaceuticalCenter, Guanganmen Hospital, China Academy of Chinese Medical Sciences (Lot No. 20020110). Jingwanhong wasthe product of Tianjin Darentang Da'er Pharmcaceutical Co., Ltd (Lot No. Z12020440). METHODS: The 114 rats were completely randomly chosen and divided into 3 groups with 36 in each: Yuhongointment group, Jingwanhong group and model group, and the left 6 rats were involved as normal control group. Ratsin the normal control group were raised routinely, and no intervention was carried out. Immediately after beingmodeled, rats in the Yuhong ointment group were spread with Yuhong ointment, 0.1 g each wound, rats in theJingwanhong group were spread with Jingwanhong, 0.1 g each wound. Dressing change was daily carried out twice regularly until wound healing; The wounds of rats in the model group were untouched. MAIN OUTCOME MEASURES: On the 1st, 3rd, 5th, 7th, 14th and 21st days after modeling, wound healing time of rats in eachgroup was recorded, and integrinβ1 absorbance and transcription factor p63 positive cell amount were compared. RESULTS: Totally 114 rats were involved in the final analysis.① Wound healing time of rats in the Yuhong ointmentgroup and Jingwanhong group was significantly shorter than that in the model group, respectively (P ＜ 0.05). ② Integrinβ1 absorbance and transcription factor p63 positive cell amount of modeled rats in the Yuhong ointmentgroup, Jingwanhong group and model group were significantly higher than those in the normal control group, respectively (P ＜ 0.05); The above-mentioned two indexes in the Yuhong ointment group and Jingwanhong groupreached the peak on the 7th day, which was earlier than peak time in the model group, and peaked intensity of twoindexes was significantly higher than that in the model group, separately (P ＜ 0.05). CONCLUSION: Yuhong ointment can promote rat wound healing, which may be associated with Yuhong ointmentinducing the proliferation and differentiation of ESCS left in the wound edge.
ABSTRACT
Objective To observe the effect of Yuhong ointment on secretion of Substance P of promoting wound healing and explore its mechanism. Methods The whole layer skin defection rat was used and randomly divided into 3 groups:Yuhong ointment group,Jingwanhong group,model group,with normal rats as control. The condition of skin wound surface and healing time were observed and recorded at 1,3,5,7,10,14,21,30 day after wound. The expression of Substance P were measured and compared by immunohistochemistry staining. Results Average wound healing rate had no significant difference between Yuhong ointment group and Jingwanhong group,which were higher than model group (P
ABSTRACT
Objective To observe the effect of Yuhonggao on proliferation and differentiation of epidermal stem cells and investigate the mechanism of promoting wound healing. Methods The whole layer skin defection rat was used and randomly divided into 3 groups:Yuhonggao group,Jingwanhong group,model group,with normal rats as control. The condition of skin wound surface and healing time were observed and recorded,and then draw the wound skin. The p63 and?1 integrin expression,the marker of epidermal stem cells,were measured and compared by immunohistochemistry staining. Results Average wound healing time hadn’t significant difference between the Yuhonggao group (13.5? 0.9)d and Jingwanhong group (12.6?0.9)d,which were better than model group (P
