Methods: Eighteen kittens of four weeks were randomly divided into 3 groups, a normal group, a model group and an acupuncture group, with six in each group. There was no treatment to those in the normal group. Unilateral eyelid suture method was used to establish the deprivation amblyopia cat model in the model group and the acupuncture group. After that, kittens in the model group didn't receive any treatment, but those in the acupuncture group were treated with acupuncture therapy of 12 weeks. Pattern Visual Evoked Potential (P-VEP) and c-Fos protein expression of visual cortex of kittens in each group were tested before and after acupuncture treatment. Results: P-VEP waveform changed significantly in kittens of the model group, the time value of P 100 was significantly delayed (P<0.01) and N 45 -P 100 amplitude was significantly lower (P<0.01) compared with the normal group. After treatment, the time value of P 100 in kittens of the acupuncture group was significantly shorter (P<0.01) and N 45 -P 100 amplitude was significantly higher (P<0.01) when compared with the model group. Expression of c-Fos positive neurons can be seen in the visual cortex layers II-IV of kittens in the acupuncture group, and the density and percentage of c-Fos immunoreactive neurons of cortex layers II-IV in kittens of the model group were significantly lower than those in the acupuncture group. Conclusion: Acupuncture has obvious improvement for abnormal changes of P-VEP waveform of monocular visual deprivation kittens; it can also increase the c-Fos protein expression in visual cortex after form- deprived.展开更多

Methods: Male SD rats were randomly divided into a normal group and a model group. UC model was established by general immunological plus local irritation method. After model identification, rats in the model group were randomly divided into a model group, a herb-partitioned moxibustion(HPM) group and a Western medicine(Salicylazosulfapyridine, SASP) group. Rats in the HPM group received treatment at bilateral Tianshu(ST 25) and Dachangshu(BL 25), two cones for each point, once a day for 7 d. SASP group rats were gavaged with SASP. The pathological scores were evaluated according to hematoxylin-eosin(HE) staining of colonic tissues. We used light microscopy to observe degree of colonic mucosal damage and the quantitative polymerase chain reaction(QPCR) to detect the expression of NF-κBp65 and PPARγ in colorectal mucosa. Results: Compared with the normal group, histopathological scores were significantly higher in the model group(P<0.05); compared with the model group, the scores were decreased significantly in the HPM group and the SASP group. Compared with the normal group, NF-κBp65 mRNA expression was increased with statistical significance in the model group(P<0.05); compared with the model group, NF-κBp65 mRNA expressions were decreased significantly in the HPM group and the SASP group. Compared with the normal group, PPARγ mRNA expression was increased significantly in the model group(P<0.05); compared with the model group, PPARγ mRNA expressions were decreased significantly in the HPM group and the SASP group. Conclusion: HPM could improve the mucosa damage of UC rats, which is possibly through down-regulating NF-κBp65 to achieve anti-inflammatory effect. Whether decreasing the PPARγ mRNA is possibly involved in preventing precancerosis will need further study.展开更多

Methods: Twelve SAMP8 mice were randomly divided into a model group and an EA group, with six in each group. Six senescence-accelerated mouse resistance 1(SAMR1) mice were prepared as blank group. Mice in the EA group received EA on Baihui(GV 20) and Yongquan(KI 1), once a day for 7 d as a course, altogether 3 courses with one day interval between two courses. Mice in the model group and the blank group were manipulated and fixed as those in the EA group. After interventions, Morris water maze was employed to test spatial learning and memory ability to evaluate EA effect; spectrophotometry was used to detect the activity of hippocampal mitochondria COX. Results: Compared with the blank group, mean escape latencies of the EA group and model group were prolonged significantly in Morris water maze tests(P<0.01), the residue duration in the former platform quadrant significantly decreased(P<0.01). Compared with the model group, mean escape latencies on 1 d, 2 d and 3 d of the EA group were significantly reduced(P<0.05), and those on 4 d and 5 d continued the decreasing tendency(P<0.01), the residue duration on the former platform quadrant was significantly prolonged(P<0.05). The COX activity tests showed that, compared with the blank group, COX activities of the model group and the EA group were significantly decreased(P<0.01); compared with the model group, COX activity of the EA group was significantly elevated(P<0.01). Conclusion: It's plausible that EA improves AD learning and memory ability by increasing mitochondria COX activity, protecting the structure and function, and improving energy metabolism.展开更多

Methods: Forty healthy Sprague Dawley rats were randomly divided into four groups, namely group A(blank control group), group B(model control group), group C(moxibustion group) and group D(herbs group). The animal model of spleen-deficiency was established by intragastric administration with Da Huang(Radix et Rhizoma Rhei) infusion. The rats in group C received moxibustion at Zusanli(ST 36), Zhongwan(CV 12), Guanyuan(CV 4), Pishu(BL 20) and Weishu(BL 21). The rats in group D received intragastric administration with Si Jun Zi decoction. The intestinal propulsion was measured by toner method, and the content of D-xylose in serum was detected by phloroglucinol method. Colorimetry method was used to detect the content of ATP and activities of Na+-K+-ATPase and Ca2+-Mg2+-ATPase in jejunum tissues. Results: Compared with group A, the intestinal propulsion rate, content of D-xylose in serum, content of ATP, activities of Na+-K+-ATPase and Ca2+-Mg2+-ATP in jejunum tissues decreased significantly in group B(P<0.05 or P<0.01). Compared with group B, the intestinal propulsion rate, content of D-xylose in serum, content of ATP, activities of Na+-K+-ATPase and Ca2+-Mg2+-ATPase in jejunum tissues increased significantly in group C and D(P<0.05 or P<0.01), while there were no significant differences between group C and group D. Conclusion: Moxibustion can increase the intestinal propulsion rate, content of D-xylose in serum and ATP in jejunum tissues, as well as the activities of Na+-K+-ATPase and Ca2+-Mg2+-ATPase of spleen-deficiency rats, which suggests that moxibustion can enhance the motility and absorption functions of small intestine by promoting the production of ATP in intestinal epithelial cells, increasing the content of membrane proteins, and improving transmembrane transport.展开更多

Metabolomics is the scientific study of dynamic chemical processes involving metabolites as well as metabolic response of living organisms. Metabolomics, a research method with integrity and dynamics, corresponds to the overall regulatory effect of acupuncture and is in line with the overall concept of traditional Chinese medicine(TCM) and the concept of homeostasis. In the recent years, metabolomics has been extensively applied to the clinical and experimental study of IBD, and its potential applied value has been unanimously acknowledged by the researchers. In this article, the application status of metabolomics in acupuncture is summarized, and the research ideas to study the mechanism of acupuncture in the regulation and control of IBD by metabolomics are preliminarily explored.展开更多
