Objective To investigate the expression of TLR2 and HIF-1α in pancreatic cancer and explore the relationship between TLR2 or HIF-1α protein and the clinical or pathological changes in pancreatic cancer. Methods The mRNA of TLR2 and HIF-1α in 30 cases of pancreatic cancer and its adjacent tissues were detected with real-time PCR and with immunohistochemical methods in 65 cases of pancreatic cancer and 38 cases of corresponding adjacent tissues. The relationship between TLR2 or HIF-1α and pathologic features of pancreatic cancer was analyzed. The correlation between TLR2 and HIF-1α in pancreatic cancer was also assessed. Kaplan-Meier method was used to assess the impact of TLR2 or HIF1αexpression on survival. Results The relative quantification of TLR2 mRNA and HIF-1α mRNA in pancreatic cancer tissues was 0.84±0.17 and 0.87±0.11, respectively, which was significantly higher than that in adjacent tissues 0.70±0.13 and 0.68±0.13 respectively,P＜0.05. The protein expression of TLR2 and HIF-1α in pancreatic cancer tissues was 63. 10% and 70.8%, respectively, significantly higher than that in adjacent tissues (34.20% and 36.8%, respectively). There was no significant correlation between the expression of TLR2 or HIF-1α protein and the age, gender, tumor location, the degree of differentiation in patients with pancreatic cancer (P＞0.05). However, there was significant correlation between the expression of TLR2 or HIF-1α protein and tumor size, lymph node metastasis, venous invasion and clinical staging. TLR2 and HIF-1α had a significant impact on survival. Conclusion TLR2 and HIF-1α overexpressed in pancreatic cancer and TLR2 signaling pathway may promote development of the pancreatic cancer with HIF-1α together.

BACKGROUND: Electro-acupuncture therapy shows good central and peripheral analgesic effects. Several studies have shown that transforming growth factor β (TGF-β) plays an important role in the pathogenesis of knee osteoarthritis. OBJECTIVE: To investigate the mechanism underlying electro-acupuncture treatment of knee osteoarthritis. METHODS: A total of 80 healthy male 3-month-old Sprague Dawley rats were randomly and evenly divided into normal, model, electro-acupuncture and drug groups. Rat models of knee osteoarthris were estbalished by ligating the femoral veins and forcing rats to do activies. At 1 month after knee osteoarthris induction, the electro-acupuncture group rats received electro-acupuncture therapy at two acupoints Neixiyan (EX-LE4) and Dubi (ST 35) with a depth of 0.1 cun (pulse 2 Hz, 20 minutes, once a day). The drug group rats were intraarticularly administerd sodium hyaluronate (0.1 mL/administration, once a week). After 2-week treatment, synovial tissue of the knee joint was harvested to determine the exprssion of TGF-β1, TGF-β1 receptor Ⅰand TGF-β1 receptor Ⅱ. RESULTS AND CONCLUSION: TGF-β1 expression in synovial tissue of the knee joint was significantly increased after knee osteoarthris (P < 0.05), but after electro-accupuncture therepy or sodium hyaluronate treatment, TGF-β1 expression was significantly decreased (P < 0.05), moreover, TGF-β1 receptor Ⅰ, Ⅱ expression was signficantly decreased (P < 0.05). These findings suggest that electro-acupuncture for treatment of knee osteoartheis improves the symptoms of osteoarthris by downregulating TGF-β1 expression, and reduction in TGF-β1 receptor Ⅰ, Ⅱ expression promotes the recovery of knee osteoarthris.
