The experiment was conducted to examine the effect of copper toxicity on the peripheral blood T-lymphocyte using the flow cytometry(FCM) and ANAE.180 one-day-old Avian broilers were divided randomly into three groups,and fed diets as follows:(1)Controls(Cu 11.97 mg/kg diet) and (2)copper toxic(Cu 650 mg/kg diet,copper toxic group Ⅰ;Cu 850 mg/kg diet,copper toxic group Ⅱ) for six weeks.The ANAE positive ratios of the peripheral blood T-lymphocytes were much lower in the two copper toxic groups than in control group from 1 to 6 weeks of age(P＜0.05 or P＜0.01).Also,there was significant difference between copper toxic groups Ⅰ and Ⅱ at 1,3,5 and 6 weeks of age(P＜0.05 or P＜0.01).CD+4 T cell numbers reduced from 2 to 6 weeks of age in both copper toxic group Ⅰ and copper toxic group Ⅱ as compared with those of control group(P＜0.05 or P＜0.01).At the same time,there was significant difference between copper toxic groups Ⅰ and Ⅱ at 6 weeks of age(P＜0.05).But the numbers of CD+8 T cell were not varied from 2 to 6 weeks of age in copper toxic groups Ⅰ and Ⅱ in comparison with those of control group(P＞0.05).The CD+4/CD+8 ratio was lower from 2 to 6 weeks of age in copper toxic groups Ⅰ and Ⅱ than in control group.The results showed that copper toxicity could suppress the development of T-lymphocytes and reduce the peripheral blood T-lymphocyte populations.Potential mechanisms underlying these observations are also discussed.

Antimicrobial peptides are a class of small peptides with anti-extrogenous pathogen activities.They are derived from organism and possess antibacterial,antifungus,antiviruses and anticancer cell actions.In recent years,it’s found that some microbial pathogens are able to resist antimicrobial peptides.The constitutive and inducible mechanism of a pathogen resists a given peptide were reviewed in this paper.

Objective To discuss the diagnosis and surgical treatment of multiple endocrine neoplasia 1 (MEN1). Methods The clinical data of MEN1 from 1974 to 2005 were retrospectively analyzed. Results There were 17 cases of MEN1 in our group. Among them, 11 cases were from 4 families. MEN1 gene mutation was detected in 14 cases admitted after 1997. There were 11 cases of pHPT, 6 cases of insulinoma, 8 cases of pituitary adenoma, 6 cases of adrenal adenoma, 2 cases of thymic carcinoid and 2 cases of collagenoma. Two patients had respectively 4 glands involved, 3 patients had 3, 7 patients had 2 kinds of gland involved respectively. Four patients had only one kind of gland involved. A 12 year old girl had no clinical symptom and biochemical change. Six patients presented with nephrolithasis, 6 patients had impaired pancreatic endocrine function. Subtotal parathyroidectomy was performed in 4 patients of pHPT, and one patient received parathyroid adenoma enucleation. Insulinomas were enucleated in 4 patients. Two patients underwent thymus tumor extirpation. Conclusions MEN1 varies in symptoms, even those from the same family. Cermline mutation test helps establish diagnosis. Operations should be aiming at tumor resection as well as the improvement of life quality.

Objective To discuss the diagnosis and surgical treatment of multiple endocrine neoplasia 2 (MEN2). Methods The clinical data of 28 MEN2 cases from Jun 1997 to Jun 2006 were retrospectively analyzed. Results There were 25 cases of MEN2a and 3 cases of MEN2b. Among the patients of MEN2a, 23 patients were from 7 families with mutation of codon 634, exon 11 of RET, 3 patients of MEN2b had mutation of codon 918, exon 16 of RET and no family history. Twenty-two cases of MEN2a had thyroid masses with elevated calcitonin level, in which 17 were pathologically diagnosed as medullary thyroid carcinoma (MTC) ,12 patients had pheochromocytomas. Among them, 5 were of multiple foci and 2 were malignant. Five patients presented hyperparathyroidism and 3 patients were asymptomatic without biochemical alterations. Three MEN2b patients had MTC and mucosal ganglioneuromatosis with Marfanoid, one patient had bilateral pheochromocytoma. Total thyroidectomy with bilateral dissection of regional lymph nodes was performed in 12 patients of MEN2a, and nodule enucleations was done in other 5 patients followed by persistent elevated calcitonin level. Nine MEN2a patients underwent pheochromocytoma enucleation including bilateral adrenal resection in 3 cases. Three MEN2b patients underwent total thyroidectomy with bilateral lymph node dissection. Conclusions MTC is the most often complications of MEN2. Germline mutation test helps to make early diagnosis. Radical total thyroidectomy in young patients may prevent MTC.
