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.

Objective To observe the effects of Suoquan Wan(SQW) on the endocrine and immune function of the polyuria rats with kidney-yang deficiency. Methods The model rats were induced by gastric infusion of adenine(250 mg/kg) for 4 weeks, then treated respectively with SQW (at low, middle and high dose respectively), Shenqi Wan and desmopressin for another 4 weeks. The bodyweight and organ index were recorded, and serum cortisone concentration were detected. T cell subsets in peripheral blood were determined by flow cytometry. Results The bodyweight of rats in model group was lower than that in the normal control group. And the bodyweight of rats in desmopressin group, middle-and high-dose SQW groups differed from that in the model group (P < 0. 05 or P < 0. 01). The decreased organ indexes of pituitary, adrenal and thymic glands were found in the model group (P < 0. 05 or P < 0. 01 compared with the normal group). The thymus index was elevated in all the medication groups except the low-dose SQW group (P < 0. 05). The elevated organ indexes of pituitary and adrenal glands were only found in Shenqi Wan group and high-dose SQW group (P < 0. 05). In the model group serum cortisone concentration was decreased (P < 0. 01). In Shengqi Wan group and middle-and high-dose SQW groups, the cortisone concentration was significantly increased (P < 0. 05 or P < 0. 01, compared with the model group). In the model group, the percentages of CD3+ and CD3+/CD4+ T cell subsets in pe-ripheral blood were decreased, and the percentage of CD3+/CD8+ T cell subset was increased (P < 0. 05 or P < 0. 01 compared with the normal group). Compared to the model group, the percentages of CD3+ and CD3+/CD4+ T cell sub-sets were increased and the percentage of CD3+/CD8+ T cell subset was decreased in SQW group and Shenqi Wan group. But the differences of T lymphocyte subsets were insignificant between desmopressin group and the model group. Conclu-sion SQW can regulate the endocrine and immune function of the polyuria ratwith kidney-yang deficiency.

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.
