The habenula complex,an ancient and conservative nucleus during biological evolution, is involved in many i mportant biological functions,such as maternal behavior,pain,sleep,learning and reward.As an important node in the dopamine reward network,its functions(including the maintenance of individual survival while avoiding disadvantages)and mechanis m in the reward process have attracted wide attention.The dysfunction of habenula is closely related to many psychotic disorders,such as de-pression,schizophrenia and drug habituation.Habenula may also become a potential target for clinical treatment of these mental illnesses.So clarifying the role and neurobiological mechanisms of habenula in the central nervous system is of great theoretical and clinical value.

Purpose:To study the efficacies and adverse effects of three different regimens in treatment of patients with gastrointestinal adenocarcinoma, which consisted of two doses of CF(20 mg/m 2, 200 mg/m 2) and two methods of administration of 5-Fu (continuous intravenous infusion and two hours per day intravenously) and DDP 20 mg/m 2. Methods:We selected 36 cases with GI adenocarcinoma and randomizedly divided them into A and B groups, who were hospitalized from January 1999 to November 2000. At the same time, 29 cases hospitalized from April 1997 to December 1998 with the same disease were designated as C group (control) . A group: CF 200 mg/(m 2.d) for 5 days, 2 hours intravenously ; 5-Fu 3 g/m 2 , continuous intravenous infusion during 5 days; DDP 20 mg/(m 2.d) for 5 days, 2 hours IV. B group: CF 20mg/(m 2.d) for 5 days, 2 hours, IV.; the dosage and usage of 5-Fu and DDP as A group. C group: CF 200 mg/m 2, usage as A, B groups; 5-Fu 600 mg/(m 2.d) for 5 days, 2 hours; dosage and usage of DDP as A, B groups. One cycle of these regimens consisted of three weeks and they were evaluated after three cycles. Results:There were 8 cases of gastral cancer and 12 of rectal cancer in A group whose response rates were 50% and 41.7% respectively. B group had 7 cases of gastric cancer and 9 cases of rectal cancer, their response rates were 42.9% and 44.4%. C group consisted of 14 cases of gastric cancer and 15 cases of rectal cancer, whose response rates were 35.7%and 40%, respectively. Adverse effects included hematological, renal and bladder and gastrointestinal toxicity. A group was similar to B group. C group had more renal and bladder toxicities(27.5%) and incidence of phlebitis was 34.5%. Conclusions:Combination regimen of low dose of CF, continuous intravenous infusion of 5-Fu and DDP is of better efficacy, tolerance and relative economy, especially suitable for to the elderly patients.

Objective: To investigate the method of using tubular demineralized tubular bone matrix scaffold composited with marrow stromal osteoblasts to fabricate tissue-engineered bone in vivo. Methods: Marrow stromal cells were harvested from illiac bone of 5 New Zealand rabbits respectively. After being cultured and multiplied in vitro, marrow stromal cells were induced to differentiate to osteoblasts with dexamethasone. The induced cells were harvested and mixed with 1.5% alginate sodium solution to generate a cell suspension. The suspension was dropped into tubular demineralized bone (1~1.5 cm in length, 0.2~0.5 cm in diameter) and then gelled with 2.5% CaCl 2. The demineralized tubular bone matrix/osteoblasts composites were placed in the dorsum of the rabbit subcutaneously as autogenous cells transplantation. Samples were investigated 6 and 12 weeks after implantation with histological and roentgenographic examination. Results: Osteoid tissue and new bone were observed in 4 weeks. In 8 weeks, more new bone formation, cells lied in the lacunae and arranged in order were found.Conclusion: Demineralized tubular bone matrix can be used as scaffold for the marrow stromal osteoblasts and alginate which was employed as three dimension carrier for cell growing and producing extral cell matrix.
