Objective To explore the therapeutic effect and application value of retroperitoneal laparoscopic combined with resectoscopic radical nephroureterectomy for upper tract urothelial carcinoma Methods From Jan.2006 to Jul.2009,fifteen upper tract urothelial carcinoma patients underwent excision of bladder cuff with resectoscope at first,and then retroperitoneal laparoscopic radical nephroureterectomy.All tumors were confirmed to be localized,stage T1-T3.Clinical outcomes of the patients were retrospectively analyzed.Results Mean operative time was 150 (range:120-180) minutes and blood loss volume was 200 (range:100-400)ml.The function of intestinal canal recovered after 24-48 hours,the drainage tube could be removed after 3-4 days.Catheter was kept for 7-10 days.During the follow up for 1-40 months,all the 15 patients survived with one retroperitoneal lymphatic metastasis.There were no severe complications in perioperative and postoperative period.Conclusions Retroperitoneal laparoscopic combined with resectoscopic radical nephroureterectomy may be a practical surgical procedure for upper tract urothelial carcinoma patients with less intraoperative blood loss and early recovery.

Aim To investigate the effects of maternal chronic aluminum exposure on memorial behaviour and hippocampal intracellular Ca2+ concentration ([Ca2+]i)on their offspring after the induction of LTP(long-term potentiation). Methods Adult Wistar rats (150~200 g) were exposed to aluminum by drinking distilled water, the concentration of AlCl3 is 0.015 mol?L-1(2 g?L-1) and 0.03 mol?L-1(4 g?L-1) aluminum chloride (AlCl3) solution, respectively, for 30 days prior to mating and during the whole gestation and suckling period. Their offspring were distributed into three experimental groups: control group; two exposed groups (represented by 0.2%-Al and 0.4%-Al ) administrated aluminum exposure ended at postnatal day 21. The brain tissue and blood aluminum levels were measured by Atomic absorption spectrometry (AAS). Memorial ability of the offspring was tested by Step down test.[Ca2+]i was measured by the technique of Fura-2/AM calcium ions fluorescence indicator. Results The mean aluminum content in blood and brain tissue was significantly higher than the control group(P0.05), but was significantly decreased in 0.4%-Al exposed group(P

OBJECTIVETo evaluate the protective effects of punicosides on alcohol induced acute liver injury in mice and its possible mechanisms as well.

METHODThe 60 mice were randomly divided into normal control, model group, three dose groups of punicosides with low, medium and high, then there is silibinin group. Three dose groups of punicosides and silibinin were given in advance by gavage for 4 weeks, then the mouse model of alcoholic acute liver injury was established. The serum levels of ALT, AST and TG were determined, and the mice were killed to calculate somatic index of liver, thymus as well as spleen. MDA, SOD, GSH-Px and GSH-ST were detected in the liver homogenate. Histopathological changes of the liver were observed by HE staining. The expression of MCP-1 and NF-kappaB in the liver tissues were detected by immunohistochemistry.

RESULTMid and high dose of punicosides reduced the liver index in mice significantly, improved liver steatosis, decreased the level of ALT, AST and TG in serum and the content of MDA in liver homogenate, furthermore the two dose groups increased the activity of SOD, GSH-Px and GSH-ST, inhibited the expression of MCP-1 and NF-kappaB in liver tissue.

CONCLUSIONPunicosides can protect the acute liver damage induced by alcohol.
