Effects of acupuncture and moxibustion on histamine and inflammatory factors in the skin tissue at Tianshu (ST25) of rats with Crohn disease / 针灸推拿医学（英文版）

Objective: To explore the potential mechanism of acupuncture and moxibustion in treating Crohn disease (CD) by evaluating the changes in histamine and inflammatory factors in the skin tissue at Tianshu (ST25) of rats.Methods: Fifty-eight Sprague-Dawley rats were randomly divided into a normal group (n=14) and a CD-modeling group (n=44). Rats in the CD-modeling group received enema with 2,4,6-trinitrobenzene sulfonic acid plus ethanol to establish CD models. The enema was repeated once every 7 d for a total of 4 times. After modeling, four modeled rats and four normal rats were randomly selected for model identification. After the CD model was successfully established, the remaining rats in the CD-modeling group were randomly divided into a model group, an acupuncture group, a moxibustion group, and a Western medication group, with ten rats in each group. The rats in the acupuncture and moxibustion groups were treated with acupuncture or moxibustion at Tianshu (ST25) and Shangjuxu (ST37); the rats in the Western medication group were treated with mesalazine enteric-coated tablets by gavage for continuous 7 d. After the intervention, the colon tissue of rats in each group was collected. After gross observation, hematoxylin-eosin (HE) staining was performed to further observe the pathological changes. The expression of histamine in the skin tissue at Tianshu (ST25) was detected by enzyme-linked immunosorbent assay. The expression of tumor necrosis factor (TNF)-α, interleukin (IL)-1β, IL-18, IL-10, and IL-6 in the skin tissue at Tianshu (ST25) was detected by Western blotting. Results: Compared with the normal group, the colonic wall of rats in the model group showed cobblestone-like changes, local ulcers, and polyps in dark red and thickening and hardening. HE staining showed local loss of mucosal epithelial layer and formation of slit-like ulcers, destruction of mucosal glands, edema, and infiltration of inflammatory cells in lamina propria and submucosa, and occasional formation of sarcoid-like granuloma. The levels of histamine and IL-6 were significantly up-regulated (P<0.01, P<0.05), and the levels of TNF-α, IL-18, and IL-10 were significantly down- regulated (P<0.01 or P<0.05) in the skin tissue at Tianshu (ST25) of rats in the model group. Compared with the model group, the pathomorphological damage of the colon tissue of rats in the acupuncture group, moxibustion group, and Western medication group was significantly improved. The levels of histamine and IL-6 were significantly down- regulated (P<0.01, P<0.05), and the level of IL-10 was significantly up-regulated (P<0.01) in the skin at Tianshu (ST25) of rats in the acupuncture group. The levels of histamine and IL-6 were significantly down-regulated (P<0.01, P<0.05), and the levels of TNF-α, IL-18, and IL-10 were significantly up-regulated (P<0.01 or P<0.05) in the skin tissue at Tianshu (ST25) of rats in the moxibustion group. The level of histamine was significantly down-regulated (P<0.01), and the levels of IL-18 and IL-10 were significantly up-regulated (P<0.05, P<0.01) in the skin tissue of rats in the Western medication group. Compared with the acupuncture group, the level of IL-10 in the skin tissue at Tianshu (ST25) of rats in the moxibustion group was significantly up-regulated (P<0.01). Conclusion: The inflammatory responses in the skin tissue at Tianshu (ST25) may be the external manifestation of CD. Significant differences in the regulation of inflammatory responses in the skin tissue at Tianshu (ST25) between acupuncture and moxibustion exist, which may be caused by the differences in the stimulation characteristics between acupuncture and moxibustion.

Expressions of epidermal growth factor receptor signaling substances in gastric mucosal cells influenced by serum derived from rats treated with electroacupuncture at stomach meridian acupoints / 中西医结合学报

OBJECTIVE: To study the effects of serum derived from rats treated with electroacupuncture at stomach meridian acupoints on the expressions of epidermal growth factor receptor (EGFR) signaling substances phospholipase C gamma-1 (PLC gamma-1), protein kinase C (PKC) and c-myc in gastric mucosal cells. METHODS: Sixty rats were randomly divided into normal group, stomach meridian group, gallbladder meridian group, stomach meridian plus PD153035 group and gallbladder meridian plus PD153035 group. Water-immersion and restrained stress methods were adopted for inducing gastric mucosal injury in the rats. Gastric mucosal cells were separated by using pronase digestion method, and incubated by PD153035, a EGFR inhibitor, and 100 ml/L serum. The expression of PLC gamma-1 in the gastric mucosal cells was tested by enzyme linked-immunosorbent assay (ELISA), while the expression of PKC by isotope incorporate assay and the expression of c-myc by reverse transcription polymerase chain reaction assay (RT-PCR). RESULTS: In gastric mucosal cells, weak expressions of PLC gamma-1, PKC and c-myc were seen in the normal group, and relatively strong expressions of PLC gamma-1, PKC and c-myc were seen in the stomach meridian group and the gallbladder meridian group, among which, the expressions of PLC gamma-1, PKC and c-myc in the stomach meridian group were the strongest, and there was a significant difference between the stomach meridian group and the gallbladder meridian group (P<0.01). Relative weak expressions of PLC gamma-1, PKC and c-myc were seen in the stomach meridian plus PD153035 group and the gallbladder meridian plus PD153035 group, and there was a significant difference between the stomach meridian group and the stomach meridian plus PD153035 group (P<0.01). CONCLUSIONS: The serum derived from the rats treated with electroacupuncture at stomach meridian acupoints can activate the EGFR singling pathway, and this provides an evidence for the theory of "relative particularity between meridians and viscera" in traditional Chinese medicine.
