Objective To evaluate central pancreatectomy in pancreatic surgery. Methods The clinical data of 19 patients who received central pancreatectomy was retrospectively analyzed in the Provincial Hospital, Shandong University from Jan 2002 to Jun 2008. Results Among 19 patients, 9 patients were of islet cell tumor,4 patients were mucinous cystoadenoma,3 patients were solid pseudopapilloma, 2 patients were pancreatic carcinoid tumor, 1 patient was of cyst-solid pseudopapilloma. After resection all of them had pathological negative margin. Length of stay was ( 17. 7 ± 7. 9) days ( ranging from 10 to 40 days ). Incidence of pancreatic fistula after this pancreatectomy was 31.6%. The follow-up period was from 6 months to 6 years. All of the 19 patients were alive except 1 who was lost to follow-up after 1. 5 years. There was no recurrence nor new-onset diabetes mellitus. Conclusions Middle pancreatectomy was a proper operative approach for benign or low-malignant tumors located in the neck or the body of the pancreas. This pancreatectomy may preserve endocrine and exocrine function, and decrease the risk of postoperative new-onset diabetes mellitns.

Objective To explore the effect of curcumin on the activity and migration of as well as c-kit mRNA expression in melanocytes.Methods Human epidermal melanocytes were isolated from the prepuce in adolescents and subjected to primary culture.To estimate the effect of curcumin on the proliferative activity of melanocytes, some melanocytes were randomly divided into several groups to be cultured in the MelM-2 medium with or without the presence of 5, 10, 20 or 30 μmol/L curcumin, the MelM-2 medium containing curcumin of 5-30 μmol/L served as the drug control groups, and the MelM-2 medium without curcumin served as the blank control group.After 24 and 48 hours of culture, MTS assay was performed to evaluate the proliferative activity of melanocytes.Some cultured melanocytes were randomly divided into 4 groups to be cultured in the MelM-2 medium with 0, 5, 10 and 20 μmol/L curcumin respectively for 48hours.Then, wound scratch assay was conducted to estimate the migratory activity of melanocytes, and real-time fluorescence-based quantitative PCR to quantify the mRNA expression of c-kit in melanocytes.Statistical analysis was carried out by factorial design analysis of variance (ANOVA), one-way ANOVA and least significant difference (LSD)-t test.Results The proliferative activity of melanocytes was significantly decreased at 24 and 48 hours in the 30-μmol/L curcumin group compared with the negative control group (0.783 ± 0.053 vs.1.000 ± 0.018 at 24 hours, 0.637 ± 0.015 vs.0.993 ± 0.064 at 48 hours, both P ＜ 0.05), while no significant differences were observed between the other curcumin groups and the negative control group (all P ＞ 0.05).The 48-hour treatment with curcumin could significantly inhibit the migration of melanocytes in the 5-, 10-and 20-μmol/L curcumin groups compared with the control group (all P ＜ 0.05).The mRNA expression level of c-kit was also significantly reduced at 48 hours in the 5-, 10-and 20-μmol/L curcumin groups compared with the control group (1.799 ± 0.372, 1.539 ± 0.224 and 1.026 ± 0.038 vs.3.371 ± 0.352, all P ＜0.05).Conclusion Curcumin at low concentrations (≤ 20 μmol/L) has no obvious cytotoxicity against melanocytes, but can inhibit the migration of and c-kit mRNA expression in melanocytes, while curcumin at 30 μmol/L can promote the apoptosis of melanocytes.

Objective To investigate the effects of angiotensin Ⅱ AT1 receptor antagonist-Candesartan on production of leptin, adiponectin and TNF-? in rat. Methods 20 male Wistar Kyoto rats were randomly divided into vehicle and Candesartan treated groups. The dosage of Candesartan was 10mg?kg~ -1 ?d~ -1 . Food intake and bodyweight were recorded each week. Rats were sacrificed by decapitation after 17 weeks. Epididymal and perirenal fat were collected and weighted. Adipocytes were isolated from epididymal adipose tissue with collagenase. Diameter of adipocyte was evaluated. Blood chemistry, insulin, leptin, adiponectin and TNF-? were assayed. mRNA expressions of leptin, adiponectin and TNF-? of epididymal adipose tissue were assayed with RT-PCR. Results In Candesartan treated group, bodyweight and content of adipose tissue were significantly decreased, and adipocytes shrunk. Blood glucose and insulin levels showed no difference between two groups. Plasma leptin level and leptin mRNA expression in adipose tissue were lower, and plasma adiponectin level as well as adiponectin mRNA expression were higher in Candesartan treated group. Plasma TNF-? level was too low to detect with super sensitive kit, and mRNA expression of TNF? was decreased in Candesartan treated group. Conclusions Angiotensin Ⅱ AT1 receptor antagonist decreases the production of leptin and TNF-?, enhances synthesis as well as release of adiponectin in rat adipose tissue.
