<p><b>OBJECTIVE</b>To investigate the efficacy of immunotherapy on septic patients with Ulinastatin plus Thymosin-alpha(1).</p><p><b>METHODS</b>Seventy postoperative septic patients were divided into two groups at random: the immunotherapy group (n equal to 36) and the conventional therapy group (n=34). Patients in the immunotherapy group received intravenous Ulinastatin of 200 000 U, 3 times per day for 3 days, Ulinastatin of 100 000 U, 3 times per day for 4 days, and subcutaneous injection of Thymosin-alpha(1) of 1.6 mg, twice per day for 3 days, then once per day for 4 days. While conventional therapies such as antibiotics and fluid resuscitation were undertaken in both groups. The expression levels of serum tumor necrosis factor-alpha (TNF-alpha), interleukin-10 (IL-10), IgG, C3, T lymphocyte subsets, CD14+ monocyte human leukocyte antigen (locus) DR (HLA-DR) and patients'28-day survival rate of the two groups were observed and evaluated.</p><p><b>RESULTS</b>The survival rate was significantly higher in the immunotherapy group (63.9%; 23/36) compared with the conventional therapy group (41.2%; 14/34). The serum TNF-alpha levels [(1.38+/-0.50) ng/ml in the immunotherapy group vs (1.88+/-0.53) ng/ml in the conventional group, P less than 0.05] and the serum IL-10 levels [(217.52+/-15.71) ng/ml vs (101.53+/-16.57) ng/ml, P less than 0.05] were significantly different between the two groups. The serum IgG levels in the immunotherapy group [(17.65+/-6.81) g/L] were significantly higher than in the conventional group [(11.94+/-5.32) g/L]. There were also significant differences in the expression levels of CD4+ T lymphocyte (35%+/-13% in the immunotherapy group vs 21%+/-7% in the conventional group, P less than 0.05) and CD14+ monocyte HLA-DR (50%+/-5% in the former vs 35%+/-4% in the latter, P less than 0.05).</p><p><b>CONCLUSIONS</b>Immunotherapy with Ulinastatin plus Thymosin-alpha(1) can enhance the inflammatory response, improve the immune homeostasis, and increase the survival rate of septic patients.</p>

<p><b>OBJECTIVE</b>To investigate the drug resistance of pathogenic bacteria of nosocomial infections in the surgical intensive care unit.</p><p><b>METHODS</b>The drug resistance of pathogenic bacteria of nosocomial infections in the SICU in our hospital from January 2001 to December 2004 were analyzed.</p><p><b>RESULTS</b>The average nosocomial infections rate was 11.3%. The major sites of nosocomial infections were respiratory tract (30.9%), abdominal cavity (29.0%), bloodstream (9.7%) and biliary ducts (7.2%). The most common pathogens were pseudomonas aeruginosa (11.6%), methicillin-resistant coagulase negative staphylococci (11.1%) and candida albicans (9.7%). ESBLs-producing strains accounted for 66.2% and 58.5% of escherichia coli and klebsiella spp. respectively. Methicillin-resistant staphylococcus aureus accounted for 94.7% and methicillin-resistant coagulase negative staphylococci accounted for 88.2% in staphylococcus aureus and coagulase negative staphylococci. Carbapenems were the most powerful antibiotics against enterobacteriaceae. The non-fermenters were high resistant to antimicrobial agents. Vancomycin was the most potent antimicrobial against gram positive cocci. Amphotericin B was the most active antibiotic against fungi.</p><p><b>CONCLUSIONS</b>Most strains of pathogens were antibiotic resistant in SICU. The main pathogenic bacteria of each infection site were different. So it is essential to establish nosocomial infections surveillance system in order to prevent, control and treat nosocomial infections effectively.</p>
