摘要：
Psoriasis is a common chronic inflammatory skin disease which is characterized by hyperproliferation and aberrant differentiation of keratinocytes; however the exact pathogenesis is largely unknown. Interleukin-22 (IL-22) has demonstrated its vital role in T cell-mediated immune response by interacting with keratinocytes in the pathogenesis of psoriasis. The microRNAs (miRNAs) are a class of small noncoding RNA molecules that play important roles in cellular processes by regulating gene expression at the post-transcriptional level. MiR-330 has been reported to inhibit the proliferation and migration of mouse keratinocytes. In the present study, we indicated that miR-330 expression in lesion tissue of psoriasis patients was specifically down-regulated, and could inhibit IL-22-induced proliferation of HaCaT and HKC cell. Wnt/beta-catenin pathway plays an essential role in the pathogenesis of psoriasis. By direct targeting CTNNB1, miR-330 could significantly downregulate IL-22-induced CTNNB1 expression. In addition, we found that the downstream targets of b-catenin, CyclinD1 and Axin2, could be affected by miR-330; miR-330 could suppress CyclinD1 protein expression and rescue Axin2 protein expression. Taken together, we indicated miR-330 inhibits IL-22-induced proliferation of HaCaT and HKC cell by targeting CTNNB1 and subsequently affect the downstream factors, CyclinD1 and Axin2 for the first time, and provide diagnostic markers and a novel target for psoriasis treatment.

摘要：
目的对比观察艾灸预处理和电针预处理两种不同方法对急性胃黏膜损伤大鼠转化生长因子（TGF-α）和增殖细胞核抗原（PCNA）表达的影响差异。方法将40只SPF级的SD大鼠随机的分为4组（空白组、模型组、艾灸预处理组和电针预处理组）,艾灸预处理组和电针预处理组选取"足三里穴"、"中脘穴"分别行艾灸和电针预处理8 d后,除空白组外造模,选用无水乙醇灌胃的方法（0.5 m L/100 g）制成大鼠急性胃黏膜损伤模型。造模1 h后,用20%乌拉坦（0.6 m L/100 g）进行腹腔注射麻醉,再取材。在光镜下观察大鼠的胃黏膜组织形态学的改变,免疫组化法检测胃黏膜TGF-α、PCNA的表达。结果与空白组相比较,模型组胃黏膜中TGF-α、PCNA的表达明显升高（P<0.05或P<0.01）;与模型组相比较,艾灸预处理组和电针预处理组胃黏膜中TGF-α、PCNA的表达均有不同程度升高（P<0.05或P<0.01）;与艾灸预处理组相比较,电针预处理组胃黏膜中TGF-α的表达明显降低,具有统计学意义（P<0.05或P<0.01）,而胃黏膜中PCNA的表达则无明显差异（P>0.05）。结论艾灸预处理与电针预处理均可以减轻无水乙醇对胃黏膜造成的损伤,促进胃黏膜保护因子（TGF-α、PCNA）的表达,但艾灸预处理稍优于电针预处理。

摘要：
OBJECTIVE: To observe the effect of moxa-burning heat stimulating acupoints of Liangmen (ST 21) and Zusanli (ST 36) on the proliferation and apoptosis signaling proteins in rats with stress-induced gastric ulcer. METHODS: Forty rats were randomly divided into four groups: negative control (NC), ulcer control (UC), acupoints of stomach meridian (ASM), and acupoints control (AC). The acute gastric ulcer model was established by bound and water immersion. Rats in NC and UC groups didn't receive any moxa-burning heat stimulating treatment, while rats in ASM and AC groups were treated with buringmoxa heat stimulating the acupoints of Liangmen (ST 21) and Zusanli (ST 36) and their controlled points, respectively. Rats in all groups were sacrificed after 12 consecutive days treatment. The ulcer index was evaluated by using Guth's method. The expression of tumor necrosis factor-alpha (TNF-α), apoptotic protease activating facter-1 (Apaf-1), Caspase-3, p21 activated kinase 1 (PAK1), extracellular regulated protein kinases 2 (ERK2), phosphorylated ERK2 (pERK2), phosphoinositide 3-kinase (PI3K) and RAC-alpha serine/threonine- protein kinase (Akt) in gastric mucosa was detected by enzyme linked immunosorbent assay (ELISA). RESULTS: Compared with UC group, the ulcer index of ASM and AC groups decreased, and the injured gastric mucosa was improved, the expression of TNF-α, Apaf-1 and Caspase-3 in gastric mucosa was significantly reduced (P < 0.05), while the expression of PAK1, ERK2, pERK2, PI3K and Akt in gastric mucosa was significantly increased (P < 0.05). And ASM showed better effect than AC group (P < 0.05). CONCLUSION: Moxa-burning Heat stimulating of Liangmen (ST 21) and Zusanli (ST 36) could promote the recovery of gastric mucosal lesion probably by inhibiting cell apoptosis and promoting cell proliferation in stress-induced gastric ulcer.

摘要：
Objective: To observe the effects of moxibustion pretreatment on the protein expressions of epidermal growth factor receptor (EGFR), phosphorylation extracellular signal-regulated kinase 1/2 (p-ERK1/2) and activated protein-1 (AP-1), the key factors of extracellular signal-regulated kinase signaling transduction pathway in gastric tissue of rats with stress-induced gastric mucosal damage, and to discuss the mechanisms of moxibustion therapy in promoting the restoration of damaged gastric mucosa. Methods: Thirty Sprague-Dawley (SD) rats were randomly divided into a normal group, a model group, and a moxibustion group using the random digits table, 10 in each group. Except the rats in the normal group, rats in the other two groups were used to make stress-induced gastric mucosal damage model using restraint and cold stress. Before modeling, rats in the moxibustion group were alternately treated with moxibustion at Zusanli (ST 36) and Zhongwan (CV 12), or Pishu (BL 20) and Weishu (BL 21), once a day, for a total of 8 d. Histological changes of gastric mucosa were observed under the light microscopy, the expression of gastric tissue p-ERK1/2 was detected by immunohistochemistry assay, and the protein levels of EGFR and AP-1 were measured by Western blots. Results: Compared with rats in the normal group, gastric mucosal damage was more serious, and protein expressions of gastric tissue EGFR, p-ERK1/2 and AP-1 increased in the model group (P<0.01, P<0.05, P<0.05). Compared with rats in the model group, gastric mucosal damage was milder, and protein expressions of gastric tissue EGFR, p-ERK1/2 and AP-1 increased in the moxibustion group (all P<0.01). Conclusion: Moxibustion at Zusanli (ST 36), Zhongwan (CV 12), Pishu (BL 20) and Weishu (BL 21) could increase EGFR, p-ERK1/2 and AP-1 expression levels in gastric tissue of stress-induced gastric mucosal damage rats, maintain the information transfer function of ERK signaling transduction pathway, and promote restoration of gastric mucosal damage.
