ABSTRACT
Objective To investigate the efficacy of regional lymphadenectomy for patients with T2 gallbladder cancer. Methods From January 1990 to December 2009, 48 patients with T2 gallbladder cancer received regional lymphadenectomy following radical surgery at the Xinhua Hospital of Shanghai Jiaotong University, and their clinical data were retrospectively analyzed. Patients were divided into two groups according to the range of lymphadenectomy. Standard group (23 patients): lymph nodes in the regions of bile duct, common bile duct and hepatoduodenal ligament were dissected; extended group (25 patients): lymph nodes in the regions of hepatoduodenal ligament, head of pancreas, duodenum, portal vein, common hepatic artery and celiac axis were dissected).The condition of patients in the two groups were compared after the treatment. The morbidity and survival rate were analyzed by using Fisher exact test and Kaplan-Meier method, respectively, and the survival rates between the two groups were compared by using Log-rank test. Results No perioperative death was found in the two groups. The morbidities was 17% (4/23) in the standard group and 24% (6/25) in the extended group, with no significant difference between the two groups ( P ＞ 0.05 ). The 5-year cumulative survival rate and median survival time were 40% and 29.8 months in the standard group, and 66% and 53.2 months in the extended group, with significant differences between the two groups ( x2 = 4. 687, P ＜ 0.05 ). Conclusion Extended regional lymphadenectomy should be performed on patients with T2 gallbladder cancer if the primary lesions can be dissected radically.

ABSTRACT
OBJECTIVE: To analyze the expression of procollagen gene in fracture callus, and to search for the technique of in situ hybridization for undecalcified skeletal tissue. METHODS: In situ hybridization of procollagen gene expression was performed on the undecalcified cryosections of rat fracture callus at 7, 14, and 28 d. RESULTS: The hybridization signals achieved were clear and easy to be localized with high specificity. On the 7th day, the expressions of pro alpha1 (III) in fibroblasts and some chondrocyte-like cells were dominant; and at the end of second week high expression of type-II procollagen mRNA was observed in chondrocytes. At the end of fourth week, the cartilaginous callus was almost all replaced by woven bone tissue, and some type-I procollagen mRNA positive osteoblasts and hypertrophic chondrocytes were found scattering in the woven bone and remnants of cartilaginous callus. CONCLUSIONS: The modified method employed in this study is easier, quicker, and more sensitive with high specificity than the conventional tec hnique for in situ hybridization of procollagen gene expression of decalcified rat fracture callus. The phenomenon of shared phenotype expression, which was demonstrated among cells engaged in fracture healing, indicates an important approach to reveal the mechanism of the origin, differentiation, and orientation of cells.
ABSTRACT
Objective To describe the characteristic CT imaging of adenomyomatosis of gallbladder and to improve the diagnostic knowledge of the disease. Methods Eleven (5 males and 6 females, mean age = 43 years) patients with adenomyomatosis of gallbladder (4 diffuse, 2 segmental, and 5 fundal) confirmed by histopathology and performed by CT examination including plain, dynamic or multiphase enhancement and / or oral cholegraphic agent were reviewed. Results Correct diagnosis was made in 7 of 11 patients(3 diffuse, 1 segmental, and 3 fundal). CT findings included segmental or diffuse gallbladder wall thickening in the involved area, associated with well defined and regular borders at both of the inner and outer layers. Significant CT findings of this entity were marked enhancement of wall layers during triphase contrast CT scanning, especially at delayed scans. Rokitansky Aschoff sinuses were clearly shown by CT, presenting as characteristic "aureola " sign, when performed with application of a cholegraphic agent. Conclusion Understanding the CT findings and using the optimal methods, we can use CT scan as a valuable method to help make the diagnosis in most cases of adenomyomatosis.
ABSTRACT
AIM: To investigate the changes of intracellular calcium ion (Ca2+) concentration in mouse H9c2 (2-1) cells transfected with or without FK506 binding protein 12.6(FKBP12.6) gene by ultrasound mediated destruction of microbubbles. METHODS: The pcDNA3.1-FKBP12.6 plasmid, mingled with albumin-coated microbubbles agents, was transfected into H9c2 (2-1) cells by ultrasound-mediated destruction of microbubbles. The H9c2 (2-1) cell growth state was investigated by inverted microscope. The changes of intracellular Ca2+ concentration was determined by laser scanning confocal microscope. The FKBP12.6 protein expression was checked by immunohistochemistry. RESULTS: As compared with control cells, the H9c2 (2-1) cells, transfected with FKBP12.6 gene, grew better, had higher gross intracellular Ca2+ concentration. CONCLUSION: FKBP12.6 gene augments Ca2+ concentration in mouse H9c2 (2-1) cells, enhances the contractibility of the myocardial cell, which may be helpful to improve the myocardial dysfunction.
