RESUMO

The effects of hepatic ischemia/reperfusion (1/R) injuries on hepatocellular viability and store-operated calcium current (Isoc) in isolated rat hepatocytes and the effects of 2-APB on store-operated calcium current (Isoc) in isolated rat hepatocytes after hepatic ischemia/reperfusion injuries were studied. Hepatic ischemia and reperfusion injury model was established and whole cell patch-clamp techniques were used to investigate the effects of 2-APB on Isoc. The results showed that ischemia/reperfusion injuries could significantly reduce hepatocellular viability and further increase Isoc in hepatocytes and 2-APB (20, 40, 60, 80, 100 micromol/L,) produced a concentration-dependent decrease of Isoc with IC50 value of 64. 63 +/- 10.56 micromol/L, (n = 8). It was concluded that ischemia/reperfusion injuries could reduce hepatocellular viability, probably through increased Isoc in hepatocytes and 2-APB had a protective effect on ischemia/reperfusion-induced liver injury, probably though inhibiting Isoc.

RESUMO

The effects of hepatic ischemia/reperfusion (I/R) injuries on hepatocellular viability and store-operated calcium current (Isoc) in isolated rat hepatocytes and the effects of 2-APB on storeoperated calcium current (Isoc) in isolated rat hepatocytes after hepaticischemia/reperfusion injuries were studied. Hepatic ischemia and reperfusion injury model was established and whole cell patch-clamp techniques were used to investigate the effects of 2-APB on Isoc. The results showed that ischemia/reperfusion injuries could significantly reduce hepatocellular viability and further increase Isoc in hepatocytes and 2-APB (20, 40, 60, 80, 100 μmol/L) produced a concentration-dependent decrease of Isoc with IC50 value of 64.63±10.56 μmol/L (n= 8).

RESUMO

Objective To investigate the value of clinical use of laparoscopy combined with choledochoscopy in treatment of cholecystolithiasis complicated with choledocholithiasis.Methods Of 120 patients suffering from cholecystolithiasis combined with choledocholithiasis,56 patients underwent laparoscopic cholecystectomy together with choledocholithotomy and T-tube drainage(LCTD),and 64 patients received routine cholecystectomy and choledocholithotomy plus T-tube drainage by laparotomy.Postoperative administration of analgesics,wound infection,recovery of function of gastrointestinal tract(RFGI),and hospital stay were compared between the two groups.Results In both groups,there were no severe complications.Wound infection rate was 12.5 %,average hospital stay was(14.9?3.1) d,and RFGI was(26.1?8.6) h in routine operation group;while in LCTD group,there was no wound infection occurred,hospital stay was(5.8?1.4) d and RFGI was(10.6?3.4) h.There were significant difference in postoperative recovery conditions between the two groups(P
