Objective: To observe the therapeutic action of earth enteral nutrition after jejunum interposition in patients with carcinoma of gastric cardia.Methods: Sixty-two patients after jejunum interposition were divided into early enteral nutrition group(n=33) and parenteral alimentation group(n=29).The clinical observation index and nutrition index were compared between the two groups.Results: The enteral nutrition group had more advantages than the parenteral alimentation group in the aspects of clinical observation index postoperative complication and nutrition index.Conclusion: Early enteral nutrition could improve gastrointestinal function and nutritional state and decrease the incidence rate of postoperative complication.

Two isomers of nitrochlorobenzene (o-, and p-NCB) were treated by a Pd/Fe catalyst in aqueous solutions through catalytic amination and dechlorination. Nitrochlorobenzenes are rapidly converted to form chloroanilines (CAN) first through an amination process, and then rapidly dechlorinated to become aniline (AN) and Cl(-), without the involvement of any other intermediate reaction products. The amination and dechlorination reaction are believed to take place predominantly on the surface site of the Pd/Fe catalysts. The dechlorination rate of the reductive degradation of the two isomers of nitrochlorobenzene (o-, and p-NCB) in the presence of Pd/Fe as a catalyst was measured experimentally. In all cases, the reaction rate constants were found to increase with the decrease in the Gibbs free energy (correlation with the activation energy) of NCBs formation; the activation energy of each dechlorination reaction was measured to be 95.83 and 77.05 kJ/mol, respectively for o- and p-NCB. The results demonstrated that p-NCBs were reduced more easily than o-NCBs.

Objective To evaluate the effects of different doses of lidocaine on suppressing fentanyl-induced cough and determine a safe suppressing dose.Methods Two hundred patients undergoing general anesthesia were randomized to four groups evenly.The following medications were given within ten seconds:normal saline 10ml (groupⅠ,control group),lidocaine 1 mg/kg (groupⅡ),lidoeaine 1.5 mg/kg(groupⅢ),lidocaine 2mg/kg (groupⅣ).Toxic symptoms of lidocaine were recorded within lmin after the administration of lidocaine,then fentanyl 3?g/ kg was given intravenously within 5 seconds.Cough incidence and cough grade were recorded within 2rain after the administration of fentanyl.Systolic blood pressure (SBP),diastolic blood pressure (DBP),heart rates (HR),and satu- ration of pulse oximeter(SpO2) were recorded during different time points of induction,all recorded data were anal- ysed by the statistical software,P value

Objective To evaluate the safety of surgical procedures for patients after heart valve prosthesis implantation.Methods Clinical data of 12 cases with heart valve prosthesis implantation undergone other surgical treatment from November 1996 to December 2005 were retrospectively analyzed.All the cases had routine oral warfarin with prothrombin time (PT) of 20.0—28.3 s averaged 23.5 s, international normalized ratio (INR) for prothrombin of 1.79—2.23 averaged 1.95 and heart functional class Ⅰ—Ⅲ.Among them,appendectomy was performed in three cases with acute appendicitis,reposition and repair in one with inguinal hernia,radical gastrectomy in two with gastric carcinoma,left hemicolectomy in one,cholecystectomy in three,left femoral head replacement in one,and bilateral high ligation and ablation of great saphenous vein in one.Elective surgical operation was performed in seven cases,and emergency operation in five.In those with elective surgery,warfarin was stopped 2—3 days before operation,while 5—10 mg vitamin K_1 was injected intramuscularly 6—8 hours before emergency surgery with preoperative median PT of 15.1 and 15.3 s and median INR of 1.24 and 1.30,respectively.In operation,5—10 mg vitamin K_1 were injected intravenously into the patients by drip depending on their bleeding on the surface of wound.ECG,blood pressure,hemoglobin and oxygen saturation were routinely monitored for all the cases intraoperatively and postoperatively.For the cases with heart function above class Ⅱ,fluid infusion was adjusted based on intubated central venous pressure,and for those with general anesthesia,analyses of blood gases and electrolyte were monitored routinely in operation.Results OPeration time averaged 20—160 rain in all the 12 patients,with blood loss 5—280 ml in average and without complications of massive hemorrhage,thrombosis and heart failure.Conclusions Surgical operation was safe for patients with heart valve prosthesis implantation,if preoperative PT and INR were adjusted to about 15 s and 1.30,respectively by cessation of warfarin or application of vitamin K_1,combined with careful manipulation and strengthened perioperative management.

Objective:To study the application of HL-60 monocyte activation test in the pyrogen detection of vaccines. Methods:HL-60 cells were incubated with the standard pyrogen(endotoxin,zymosan and lipoteichoic acid)solution and the sample solution at different concentrations,and then IL-6 level was detected using ELISA kit. According to the concentration of standard pyrogen solution and the level of IL-6,the standard curve and linear relationship were obtained. Based on the IL-6 value from the sample solution,the pyrogen content of the sample was calculated. The standard pyrogen solution at middle concentration of the standard curve was used as the interference sample,and the interference assay was performed referring to the bacterial endotoxin test in Chinese pharmacopoeia. The pyrogen recovery rate and the content were detected using HL-60 / IL-6 assay in seven kinds of vaccines such as influenza vaccine(Split Virion),inactivated;hepatitis A(live)vaccine,freeze-dried;rabies vaccine(Vero Cell)for human use,freeze-dried;lyophilized human measles and rubella combined vaccine,live;measles and mumps combined vaccine, live; haemorrhagic fever with renal syndrome bivalent vaccine, inactived; group A and C meningococcal polysaccharide vaccine. Results:① The linear relationship between the pyrogen concentration and the IL-6 level was good,and R2 value was 0. 996,0. 993 and 0. 997,respectively. ② The recovery rate of pyrogen in the above vaccines ranged from 50% to 200% . ③ The endotoxin concentration of 10 batches of group A and C meningococcal polysaccharide vaccine was detected using HL-60 / IL-6 assay,and the average value of 6 batches from factory A was 134. 73 EU·ml-1 ,and that of 4 batches from factory B was 40. 75 EU·ml -1 . The pyrogen in the other vaccines was all negative. Conclusion:The HL-60 / IL-6 assay is suitable for the pyrogen detection of the seven kinds of vaccines.
