AIM: To determine the effects of NF-?B on the development of rat pancreatic fibrosis mediated by angiotensin II. METHODS: Spraque-Dawley rats (200-300g) were randomly divided into normal group, control group and losartan-treatment group. Pancreatic fibrosis was induced by injection of 2% TNBS into biliopancreatic duct. Rats in losartan-treatment group and control group were respectively treated with losartan (10 mg?kg~(-1)?d~(-1)) by gavage and the same volume of saline vehicle. The expression, distribution, and activation of NF-?B were studied by Western blot, immunohistochemistry and TransAM~(TM). Toluidine blue staining and transmission electron microscopy were also used to observe the number, distribution and degranulation of mast cells. In addition, RT-PCR was performed to detect the intrapancreatic ICAM-1 mRNA expression. RESULTS: The expression and activity of intrapancreatic NF-?B p65 protein were significantly increased on day 3 after operation, reaching peak on day 7 [(0.406?0.086) mg/g total protein]. Mast cell activation was observed and ICAM-1 mRNA levels on day 3 and 7 were up-regulated in control group. Losartan treatment inhibited NF-?B expression and activation, reduced mast cell infiltration and degranulation and decreased ICAM-1 mRNA expression compared with control rats. CONCLUSION: It might be associated with the expression and activation of NF-?B that angiotensin II mediates inflammation and fibrosis in the early stage of pancreatic fibrosis. [

AIM: To examine the effects of PPAR? activation on the growth of human pancreatic carcinoma in vitro and to explore the role of NF-?B and activator protein-1 (AP-1) in this process. METHODS: SW-1990 pancreatic cancer cells were treated with ligand of RXR?, 9-cis-RA, ligand of PPAR?, 15d-PGJ_2, and both. Antiproliferative effect was evaluated by using MTT assay; the expression of NF-?B p65 active protein was assayed by using TransAM~TM technique. Expression of c-jun and c-fos by SW1990 cells, which were treated with 15d-PGJ_2, 9-cis-RA and both at varying concentrations, were detected by RT-PCR. RESULTS: MTT assay demonstrated that 15d-PGJ_2, 9-cis-RA and the combination of both had a potent inhibitory effect on the growth of SW1990 cells in a dose-dependent manner. 9-cis-RA had a synergic action with 15d-PGJ_2 on the growth inhibition of pancreatic carcinoma. TransAM~TM showed a down-regulation trend of P65 active protein in SW1990 cells treated with 15d-PGJ_2, 9-cis-RA and both. RT-PCR demonstrated that the expression of c-jun mRNA in 15d-PGJ_2, 9-cis-RA and the combination of both-treated cells were firstly increased and then decreased, the expression of c-fos was decreased in 15d-PGJ_2 or 9-cis-RA treated SW1990 cells, but increased in cells treated with both 15d-PGJ_2 and 9-cis-RA. CONCLUSION: Activation of PPAR? exerts a negative regulatory effect on the growth of pancreatic carcinoma in vitro. Activation of RXR? has a synergic action with PPAR? agonist. The mechanism is probably associated with down-regulating the expression of NF-?B and AP-1. [

Objective To explore the influence of bacteria lipopolysaccharide on the cytokine production of flour mite allergic rhinitis patients. Methods 8 cases with perennial allergic rhinitis were selected. Then the heparin anticoagulation venous blood was taken from the same patient and was added to fetal calf serum,with ultimate volume 1 ml. The two experimental groups were added 10μg LPS and 1 μg LPS respectively, forming the high LPS dose group and low LPS dose group,while the control group was added nothing. Results The contents of IL-4、IL-5、IL-10、IL-12、IFN-γwere tested by enzyme-linked immunosorbent assay. The findings were that there was significant difference in the productive contents of IL-4、IL-5、IL-10、IL-12 and no significant difference in that of IFN-γ between the high LPS dose group and the low LPS dose group. When compared in two groups,significant difference was found in the productive contents of IL-4 ,IL-10 and IL-12 between the two experimental groups and between the high LPS dose group and the control group, while no obvious difference existed between the low LPS group and control group. However, significant difference was altogether found in the productive content of IL-5 when compared one with another among the three groups,and the result was that low dose of LPS obviously promoted the production of cytokine while high dose of LPS restrained the production of cytokine; no significant difference was found in the production of IFN-γ in all comparisons between the three groups. Conclusion This research, through the experiments in vitro, proved that LPS could effectively adjust the cytokine production of perennial flour mite allergic rhinitis patients and the balance of Th1/Th2 ,whose effect depends on the dose of LPS. This research suggested that the practical future in which special cytokine target treatment will be adopted on perennial flour mite allergic rhinitis patients.

Objective To investigate the differentiated thyroid carcinoma diagnosis and treatment options. Methods From Feb. 2002 to Jan. 2008,78 patients received different surgical resection regarding the type of tumor size,number of tumor,ages and jugular lymphatic metastasis. Patients with unilateral differentiated thyroid carcinoma underwent the resection of ipsilateral isthmus of thyroid lobe or plus partial contralateral gland,and those with bilateral-lobe underwent total thyroidectomy or near-total thyroidectomy. High-risk patients (age >45 years,tumor size >4 cm,tumor size ≤4 cm,but surpass the envelop of thyroid) were performed by functional neck dissection or lymph node dissection of central region (Ⅵ area) besides postoperative endocrine therapy. Results Eleven cases underwent the resection of ipsilateral lobe with isthmus, 19 cases underwent surgical removal of ipsilateral lobe with isthmus plus partial contralateral gland,26 cases underwent near-total thyroidectomy and 22 total thyroidectomy. 25 cases underwent functional neck dissection, 23 cases underwent neck dissection of central region. There were 68 papillary thyroid carcinoma (87. 18%), 10 follicular thyroid carcinoma (12. 82%). There were 26 cases with lymphatic metastasis of Ⅵ area. Postoperative complications included 12 cases (15.38%) with deadlimb caused by hypocalcemia, 8 cases (10.26%) with transient recurrent nerve paralysis,2 cases (2.56%) with permanent injury of recurrent laryngeal nerves, 3 cases (3. 58%) with chylous fistula. Seventy-four(94. 87%) cases were followed up postoperatively for a period from 6 months to 6 years,which showed that no death occurred,but 6 relapsed with jugular lymphatic metastasis,after reoperation no distant metastasis occurred. Survival rate was 97. 30% (72/74). Conclusion Treatment of the differentiated thyroid carcinoma should be based on the size of tumor,number of tumor,age and jugular lymphatic metastasis. Lymph node dissection of central region was necessary for high-risk patients of differentiated thyroid carcinoma.
