ABSTRACT
Objective:To investigate the efficacy of lauromacrogol injection for the treatment of post-operative breast cancer lym-phatic fistula. Methods:A mixture of lauromacrogol and air from the drainage tube was injected to the treatment group. The site of the residual cavity was bound with appropriate pressure for 24 h. The control group was treated with traditional methods. Results:The lym-phatic fistula of the treatment group disappeared after the mixture of lauromacrogol and air was injected to the patients. All of the 12 cases were subjected to a follow-up session. No recurrence of lymphatic fistula was observed. The differences between the treatment group and the control group were significant. Conclusion:The results revealed the efficacy of lauromacrogol injection for the treatment of post-operative breast cancer lymphatic fistula. Hence, this method could be applied for the preliminary treatment of lymphatic fistula.
ABSTRACT
As an intracellular non-histone chromosomal binding protein, High mobility group Box-1 ( HMGB1 ) plays an important role in maintaining the stability of the nuclear body and DNA recombination, duplication, repair and genetic transcription. Besides, extracelluar HMGB1 may serves as a "late inflammatory mediator", which start inflammatory response in the late stage of inflammation. Recent studies have found that,HMGB1 is closely related with the growth, infiltration and migration of pancreatic carcinoma. Also, HMGB1 can promote the degradation of extracelluar matrix, the infiltration and the migration of pancreatic carcinoma.
ABSTRACT
Objective To investigate the correlation of the expression of high mobility group protein B1 (HMGB1) and blood-borne metastasis in patients with pancreatic carcinoma. Methods The serum HMGB1 levels were determined by Western blot analysis in 68 patients with pancreatic cancer, 18 patients with chronic pancreatitis and 21 healthy controls. Among the 68 patients with pancreatic cancer, the serum HMGB1 levels of 37 patients before and after operation were compared. The expression of HMGB1 and CD31 were detected by immunohistochemistry in 67 patients with pancreatic carcinoma. Results The serum HMGB1 levels in patients with pancreatic cancer was (119.7±54.5) ng/ml, which was significantly higher than (40.2±25.5) ng/ml in chronic pancreatitis (P<0.001) and (13.1±4.3) ng/ml in healthy control (P< 0.001). The serum HMGB1 levels in patients with pancreatic cancer before operation was (120.2±8.2) ng/ml, which was significantly higher than (69.3±5.1) ng/ml after operation (P <0.001). The expression rate of HMGB1 in pancreatic cancer tissues was 43.6%. The expression of HMGB1 were significantly related with tumor differentiation, TNM stage, blood-borne metastasis, and vascular density(P <0.01). The HMGB1 positive tumor cells were adjacent to the blood vessels with lumen, and the rate of HMGB1 expression in intravascular tumor cells was 71%. Conclusions The HMGB1 was highly expressed in pancreatic cancer tissues. HMGB1 expression positive pancreatic carcinoma cells were prone to invade blood vessels with lumen which may be related to blood-borne metastasis in pancreatic cancer.

ABSTRACT
Objective:To investigate the immune mechanism of 5-fluorouracil(5-Fu) and Octerotide(Oct)in the treatment of severe acute pancreatitis(SAP)and it’s kidney injury.Methods:55 male SAP rats induced by retrograde infusion of 5% sodium taurocholate into bilopancreatic duct were randomly divided into 3 groups:Normal saline group(n=17)were treatmented with normal saline infusion,Oct group(n=18):The first dose of Oct was 2?g/100g iv,then 0.2?g/(100g?h)continuous injection,5-Fu group(n=20):The dose of 5-Fu was 2mg/h?12h.Rats from each group were killed at 12h after opertation.The plasma levels of tumor necrosis factor-?(TNF-?),interleukin-1(IL-1)were assessed by ELISA method.Thromboxan B_2(TXB_2)and prostaglandinE_2(PGE_2)were assessed by radioimmunoassay method.The expression of TNF-? mRNA was detected by RT-PCR.The apoptosis rate of rat kidney tissue were detected by TUNEL method.Apoptosis rate of NRK cell treated by serum of different groups were assessed by flow cytometry methods.Results:The plasma level of TNF-?、IL-1 and TXB_2 in 5-Fu and Oct group were much lower than that in normal saline group.The expression of TNF-? mRNA of kidney tissue decreased significantly after the SAP was treated by 5-Fu or octreotide.The apoptosis rate of NRK cell disposed by normal saline group,oct group,5-Fu group and control group rat plasma were (38.67?11.4)%,(20.4?18.4)%,(10.5?11.0)% and (1.7?2.2)% respectively(P
ABSTRACT
Objective:To explore the mechanism of renal injury in severe acute pancreatitis(SAP).Methods:54 SD rats were randomly divided into sham operation group(n=24) and SAP group(n=30).SAP model was induced by injection of 5% sodium taurocholate solution into bilo-pancreatic duct.Rats from each group were killed and the serum and ascite were collected at 6h,12h,24h after operation.Tumor necrosis factor-?(TNF-?)level of serum and ascite were measured by enzyme linked immuno-sorbent assay (ELISA).The expressions of TNF-? mRNA were assessed by RT-PCR analysis.The serum and ascites that had been collected at 24h after development were injected into medium of NRK cell,then the levels of TNF-? secreted by NRK cell were measured after injection 6h,12h,24h,and the cell apoptosis were also evaluated after injection 24h.NRK cell apoptosis were evaluated by flow cytometry (FCM).Results:①The serum and ascites levels of TNF-? were signficantly elevated in SAP groups compared with sham operation groups at any time point(P
ABSTRACT
AIM: To investigate whether cirrhosis affects the expression of hepatic glucuronosyltransferase (UGT) isoforms and its clinical significance. METHODS: Reverse transcription and polymerase chain reaction (RT-PCR) and Southern hybridization were used to determine the mRNA levels of five UGT isoforms in hepatic tissues. RESULTS: Compared to control group, UGT2B15 and UGT1A6 mRNA level in cirrhosis group increased by 227% and 166%, respectively. Compared to 0 fibrotic grade group, UGT2B15 mRNA levels of 1, 2, 4 fibrotic grade patients were 172%, 208% and 243%, respectively. UGT2B7 mRNA levels of 1, 2, 3 fibrotic grade patients were 156%, 208% and 192%, respectively. Inflammation grade showed no obvious effect on mRNA expression of most UGT isoforms. CONCLUSION: Cirrhosis affectes individual UGT isoform mRNA level. Degree of fibrosis has a significant effect on UGT mRNA expression.
