ABSTRACT
Objective To explore the effect of “double reinforcing and one unblocking” electroacupuncture on hepatic mitochondrial structure and ATPase activity in a rat model of senile yang deficiency. Methods Forty 5-month-old male SD rats were selected and randomly allocated to groups A, B, C and D, 10 rats each. Group A was a normal control group. A model of senile yang deficiency was made by 40 days’ subdermal injection of D-galactose and then 7 days’ intramuscular injection of hydrocortisone in the other three groups of rats. Group C received treatment with “double reinforcing and one unblocking”electroacupuncture at points Guangyuan(CV4), Zusanli(ST36) and Baihui(GV20); group D, treatment with electroacupuncture at points Zhongji(CV3), Yinlingquan(SP9) and Yintang(GV29). Treatment was given 6 times a week for a total of 4 weeks. After treatment, the anti-fatigue ability was determined by swimming exhaustion time, hepatic mitochondrial structure was observed under a transmission electron microscope and hepatic Na+-K+-ATPase and Ca2+-Mg2+-ATPase activities were measured by colorimetry in every group of rats. Results The mean swimming exhaustion time shortened significantly (all P<0.01); hepatic mitochondrial inner and outer membranes were blurred, mitochondrial ridges deformed, ruptured or disappeared and mitochondria swelled; both Na+-K+-ATPase and Ca2+-Mg2+-ATPase activities decreased (P<0.01, P<0.05) in groups B, C and D of rats compared with group A. Swimming exhaustion time lengthened significantly (P<0.01), hepatic mitochondrial structure improved significantly and both Na+-K+-ATPase and Ca2+-Mg2+-ATPase activities increased significantly (P<0.01, P<0.05) in group C compared with group B. Rat mean swimming exhaustion time shortened (P<0.05), hepatic rough endoplasmic reticula degranulated and hepatic Na+-K+-ATPase and Ca2+-Mg2+-ATPase activities decreased (P<0.05) in group D compared with group B. Conclusion “Double reinforcing and one unblocking”electroacupuncture can improve anti-fatigue ability, ameliorate hepatic mitochondrial ultrastructure, increase hepatic Na+-K+-ATPase and Ca2+-Mg2+-ATPase activities and promote hepatic energy metabolism in a rat model of senile yang deficiency.
ABSTRACT
Objective:To investigate the correlations of Lauren classification and world health organization (WHO) classification of gastric cancer (GC) with microvascular density (MVD), matrix metalloproteinase-2 (MMP-2), matrix metalloproteinase-9 (MMP-9), vascular endothelial growth factor (VEGF), vascular endothelial growth factor receptor 1 (VEGFR1), vascular endothelial growth factor receptor 2 (VEGFR2), and p53. Methods:The clinical data of 89 patients with GC were collected. The collected specimens were categorized on the basis of Lauren classification and WHO classification. CD34/periodic acid-Schiff (PAS) double staining was performed to validate MVD. Immunohistochemistry was conducted to investigate the expression levels of MMP-2, MMP-9, VEGF, VEGFR1, VEGFR2, and p53. Results:MVD was not correlated with Lauren classification or WHO classification (P>0.05). Lauren typing was associated with the expression levels of MMP-9, VEGFR1, and p53 (P0.05). Cox proportional hazards model revealed that Lauren classification and WHO classification were the prognostic factors of overall survival (P<0.05). Conclusion:This research on tumor related factors, angiogenesis, and different classifications of GC may provide new methods to treat this disease.
