Simulating physiological neuronal and hormonal conditions during digestive and interdigestive periods, the study identified the changes of the motility of biliary system including bile duct and sphincter of Oddi (SO) before and after cholecystojejunostomy. Thirty-five rabbits were divided into five groups randomly. The experimental groups received the venous injection of CCK 10 ng/kg, erythromycin 10 mg/kg, atropine 3 micrograms/kg and L-NAME 10 mg/kg respectively. Each rabbit underwent manometry through introducing a three-lumen catheter via the papilla retrogradely, using the low-compliance papillary infusion system. Then the gallbladder and the upper segment of the jejunum was anastomosed and the manometric procedures repeated after one week. SO basal pressure was increased, contraction amplitude decreased, contraction time shortened after cholecystojejunostomy. L-NAME, CCK and erythromycin could all excite SO. L-NAME could increase basal pressure and contraction amplitude, CCK increase basal pressure contraction amplitude and frequency, and erythromycin increase contraction amplitude, respectively. But comparing with that before cholecystojejunostomy, the increasing extent was decreased. The tensional and spontaneous contractions of the SO were under the control of the neural and hormonal mechanism. The anastomosis of gallbladder and jejunum and the drainage of bile made the tensional contraction stronger, but the spontaneous contraction weakened after the operation due to the decreases of the sensitivity of SO to hormonal factors. The clinical symptoms may not be relieved when the patients with SO dysfunction accepted cholecystojejunostomy.

Chinese Journal of Pathophysiology 1989;0(06):-
In order to study the effects of biliary high pressure on splanchnic major nerve and the its significance during sever type acute cholangitis(ACST), using a self-made catheter with a blind cyst at the biliary tract, an observation was completed on biliary compression of 150mmHg (20kPa) in big ear white rabbits, nervous impulse frequercy of splanchnie major nerve and blood pressure was measured at the same time. The results showed that a significant decrease in blood pressure(P0.05), the authors believe that activity of splanchnic major nerve is related to the decrease of blood pressure in earlier stage of ACST.
4.Effect of biliary hypertension on cardiovascular activity in rabbits
Chinese Journal of Pathophysiology 1986;0(03):-
In order to study the effect of acute biliary hypertension on cardiovascu-lar activity, an experiment has been done on Japanese big ear white rabbits, using a self-made catheter with an inflatable rubber bag fixed to its anterior end. It was insertedinto the extrahepatic biliary tract via the duodenum, biliary high pressure of 8-20 kPawas created and maintained for 2 h by inflating the bag with water. A significant decreaseof cardiac output (CO) and fall of the arterial blood pressure were found during theexperiment (P0.05). These results indicated that the increase ofthe biliary pressure without infection could also make CO decrease, so it was a direct rea-son for falling of blood pressure, it was also an important factor causing the decline ofblood pressure in the ealier stage of severe acute cholangitis (ACST).

Parenteral & Enteral Nutrition 1997;0(01):-
Objectives:To determine if enteral nutrition can protect the gut barrier in patients with damaged hepatic function and draw the clinical significance from it. Methods:76 patients whose hepatic function was in Child B or C grade were randomly assigned in enteral nutrition group(EN,30 cases),total parenteral nutrition group(TPN,26 cases) and control group(CON,20 cases).They were given with different nutritional support. Nutritional parameter and hepatic function indexes were massured at the day before operation,5th day and 10th day after the operation respectively.The concentrations of lactulose(L) and Mannitl(M) were detected in the urines with pulsed electrochemical detection(HPLC PED) and the L/M ratio was calculated. Results:No significant differences of hepatic function changes were observed between EN group and TPN group.It was the earlist that EN group reached the positive nitrogon equilibrium among the 3 groups and the loss of body weight after operation was the lowest in EN group There wes no change in L/M ratio in EN group, but the change was significant in TPN group( P

In order to evaluate the value of angiographic diagnosis and interventional therapy in the patients with massive hemobilia, 10 patients with massive hemobilia were analyzed retrospectively from Sep. 1990 to Sep. 1999. All of them underwent emergency celiac and selective right or left hepatic artery angiography. The patients were diagnosed rapidly and treated successfully by embolization of the hepatic artery branch proximal to t he bleeding point, and hemorrhage was stopped immediately. Two out of 10 patients were embolized two times for bleeding again. All patients were alive and followed up for 3 months to 5 years. As a safe, reliable and mininally invasion method, selective hepatic artery angiography and embolization was proved to be an important diagnostic and therapeutic means for massive hemobilia, which had obvious advantages of minimally invasive reatment in unstable patient over surgery and should be the first choice for such patients.
