Objective In order to sum up the cervical manifestation of the Hodgkin's disease.Methods A retrospective review was made on 46 cases of the Hodgkin's disease involving the neck between 1999 and 2002.Specially the clinical presentations,staging for the Hodgkin's disease involving the neck was sought.Results The Hodgkin's disease occurs in any ages,especially the younger and the old.The diameter of lymph node of neck is usually under 5 cm,the biggest reaches 16 cm.Lymph node of neck in the side region of neck is most common,and the anterior region of neck takes the second place.The nod sclerosis type and the mix cell type are most common in the Hodgkin's disease.Conclusion We must learn the law of the Hodgkin's disease involving the neck,if only we do this,we will detect the disease early and treat early.

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.

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).

Objective To investigate the therapeutic effect of microencapsulated xenogenic hepatocytes transplantation on rat fulminant hepatic failure(FHF).Methods Isolated guinea pig hepatocytes were microencapsulated with alginate-chitosan-polyethyleneglycol(ACP).The microencapsulated hepatocytes(MCHC) were implanted into the peritoneal cavity of Wister rats 24 hrs before the FHF model,which was surgically induced by 90% hepatectomy.After 24hrs of the FHF,the serum ALT,total bitirubin(TB),blood suger(BG) and PT were determined,and the microscopic appearance,function and nember of the implanted microencapsulated hepatocytes were observed,as well as the survival time and life quality of the FHF rats. Results Compared with the control group,the rats in the MCHC implantation group showed milder symptoms of central nervous system and less serious ascites.The ALT,BS, TB,and PT in the MCHC implantation group were all improved significantly (P

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.

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

Objective To summarize the clinical experience of Gilbert tension-free hernioplasty in the elderly patient under local anesthesia. Methods Seventy-six elderly hernia patients operated by Gilbert tension-free hernioplasty under local anesthesia were analyzed in operating time, postoperative complications, hospitalization days and recurrence rate, etc. Results Patients with abdominal hernia were all cured. The average operation time was 25.7 minutes and the time staying in bed after operation was 2-5 hours. The complications of incision pain, foreign body sensation and scrotum hydroceles after operation were observed in 8, 4 and 3 patients respectively. The average hospitalization period was 2.3 days. All patients were followed-up for 1-12 months and no recurrence and infection were observed. Conclusions Gilbert tension-free hernioplasty under local anesthesia is an ideal operation to treat abdominal hernia for elderly patients with less interference to physiological function, quick recovery and less complications.

Objective To investigate the relationship between the expression of urokinase-type plasminogen activator (uPA) mRNA and breast cancer, lymph node metastasis. Methods Sixty patients with breast tumor were selected randomly and the expression of uPA mRNA was detected with RT-PCR. The patients were divided into benign group (18 cases) and malignant group (42 cases) which included 22 cases with lymph node metastasis and 20 cases without lymph node metastasis. The relationship between uPA mRNA expression and breast cancer, lymph node metastasis was analyzed. Results Among these 18 benign tumors, low expression of uPA mRNA was found in 2 cases and the others were negative. While in 42 cases of malignant tumor, uPA mRNA were positive in 22 cases of lymph node metastasis, 16 of which were high expression, 5 of which were moderate expression, and 1 was low expression. uPA mRNA were positive in 18 of 20 cases of nonmetastatic lymph node, 1 of which was high expression, 5 of which were moderate expression and 12 of which were low expression, the other 2 were negative expression. The expression of uPA mRNA had significant difference between benign and malignant tumors ( P

Objective To investigate the expression of urokinase-type plasminogen activator (uPA) mRNA in gastric cancer tissues and cancer-adjacent tissues and the relationship between its expression and biologic behavior of tumor. Methods Fourty-eight cases with gastric cancer were detected for the expression of uPA mRNA by fluorogenic probe quantitative reverse transcription polymerase chain reaction (RT-PCR). Results The positive expression rate of uPA mRNA was 83.3%, 25.0%, 93.8% and 62.5% in gastric cancer tissues,cancer-adjacent tissues, gastric cancer tissues with lymph node metastasis and with non-lymph node metastasis respectively. Expression of uPA mRNA was positively related with the invasion depth of gastric cancer.Conclusion Expression of uPA mRNA is significantly increased in gastric cancer and it can be used as an indicator to judge the metastasis and prognosis of tumor.
