[Primary study on the influence of blood transfusion on the STR genotypes of recipient's blood].

OBJECTIVE: To investigate whether any change occurred in recipients' blood collected at different times after transfusion with different quantity of blood. METHODS: Three patients were transfused with 400 ml, 800 ml and 1200 ml blood separately. The blood samples were collected from the recipients before transfusion and at 4 h, 8 h, 12 h after transfusion, and from the donors. DNA were extracted by Chelex-100 method and were amplified by the polymerase chain reaction (PCR). Six loci of D1S549, D18S865, D3S1754, D12S391, D12S375, D6S477 were selected. The PCR products were analyzed by polyacrylamide gel (PAG) vertical electrophoresis and silver staining. RESULTS: The investigations on the six STR loci revealed that the patients' STR genotypes remained unchanged within 12 h after blood transfusion. CONCLUSION: The STR genotypes of the donors would have no influence on the STR genotypes of the patients within 12 h after transfusion providing the volume of blood transfused is less than 1200 ml.

[Clinical study on the treatment of severe acute pancreatitis by integrated traditional Chinese medicine and Western medicine].

OBJECTIVE: To sum up clinical experiences and formulate a new treatment program for the effective managment of severe acute pancreatitis(SAP) by integrated TCM and western medicine. METHODS: The therapeutic regimens and end results of 1376 cases of SAP in three periods were reviewed and analyzed. Period I (1980-1990) was characterized by early surgical intervention supplemented with integrated traditional Chinese and western medical therapy, period II (1991-1993) by integrated traditional Chinese and western medical therapy supplemented with surgery for early complications, and period III (1994-2003) by integrated traditional Chinese and western medical therapy supplemented with surgery for local infectious complications at a late stage in the course of disease. RESULTS: With use of integrated traditional Chinese and western medical therapy in the treatment of SAP, the proportion of surgical operation and the case-fatality rate kept declining in the three consecutive periods, the proportions of operation being 77.59%, 54.54% and 19.38%, and the case-fatality rates being 40.52%, 17.17% and 10.77%, respectively. CONCLUSION: Integrated TCM and western medicine is effective for most SAP cases, and surgery is indicated mainly for late complications such as necrotizing infection. Early surgery should be handled with more circumspection and strictness in most of the patients with SAP.
