Using 22 monoclonal antibodies (McAbs) as probe to analyse the antigenic determinants of crystallized Tian Hua Fen (THF) or Trichosanthin protein in ELISA additivity test was reported. The 22 McAbs were come from five fusions, each from different fusion well. The isotype of 22 McAbs were identified by immunodiffusioo test, 20 McAbs belong to IgG_1 subclass, 1 IgG_(2a) subclass and 1 IgM class. Based on the results obtained from ELISA additivity test, 22 McAbs could be clustered into six distinct groups. It indicates that there are six different antigenic determinants in crystallized THF, each can be recognized by some McAbs. The results coincide with the calculation of B cell recognized antigenic determinants obtained by prediction from amino acid sequences of THF protein, The work has laid a foundation for further exploring the structure-function relationship of THF protein on molecular level .

The clinical data of 195 patients in intensive care unit (ICU) were retrospectively analyzed. The total nosocomial infection rate was 15.5% in this group of patients; respiratory tract was the predominant site of infection (71.0%); the most common infection microorganism was Gram-negative bacteria (65. 1% ) ,the top two pathogens were Escherichia (32. 6% ) and Staphylococcus ( 11.6% ). The risk factors of nosocomial infection in ICU were female sex, high age, invasive mechanical ventilation, long hospitalization in ICU, multiple organ dysfunction syndrome (MODS), etc.

Objective:To explore the application value of multislice spiral CT scanning on abdomen for the detection of complication of acute pancreatitis.Methods: 120 patients with acute pancreatitis were divided into observation group (70 cases) and control group (50 cases) according to different detection method. The patients of control group were applied basic clinical detections included X-ray radiography and ultrasound imaging, while patients of observation group were supplemented CT detection besides these detections of control group. And situation of complication of patients in two groups were observed.Results: The positive rate of complications, which involved pancreatic pseudocyst, cellulitis, complications of gastrointestinal tract, pancreas hemorrhage and pancreatic ascites, in observation group was 97.14%, that was significant higher than that (62.0%) of control group (x2=24.74,P<0.05). Among 20 patients with pancreatic pseudocysts, there were 9 patients located at tails of pancreases, 6 patients located in bodies of pancreases, 3 patients located in small omental bursas, 2 patients located at heads of pancreases, and the CT images of them showed quasi-circular liquid form density lesions with clear boundaries appeared in lesion field. The CT images of cellulitis showed the volume of pancreas increased and the boundaries were fuzzy, and a larger range of density lesions with irregular soft tissue shape appeared in its periphery. CT detetions of gastrointestinal complications showed fuzzy point-shaped, strip-shaped and flake-shaped soft tissue-styled density shadow appeared in gastrointestinal tracts. The CT image of pancreatic ascites showed intraperitoneal fluid density shadow.Conclusion: Abdominal CT scan applied on patients with acute pancreatitis can increase the positive rate of complications and may be used as preferred detection method for clinical evaluation on the complications of acute pancreatitis.
