Objective To study the therapeutic effect of anti-LPS antibody and different antibiotic in treatment and prevention of sepsis a common complication of serious burns.Methods Twenty-nine patients were divied into anti-LPS+antibiotic treatment group and antibiotic treatment group.Plasma endotoxin,serum TNF,IL-6 and IL-8 were detected at different time phase after burn.Results The results showed that the antibodies to LPS could decrease the level of LPS,IL-6,IL-8 and TNF obviously,but some antibiotic couldn't decrease the level of LPS,IL-6,IL-8 and TNF obviously in blood.Impenem was a weak endotoxin inducer and ceftazidime and ciprofloxacin were stronger endotoxin inducers.Conclusion The appropriate selection of antibiotics and anti-LPS antibody has a considerable influence on treating sepsis and its complications after serious burns.

Objective To explore the effects of recombinant human growth hormone(rhGH) on the serum levels of cytokines in severely burned patients.Methods Thirty-six burn patients were en-rolled in the study and were randomly divided into 3 groups according to the rhGH dosage used,i.e. small(0.3IU?kg -1 ?d -1 ,A),large(0.6IU?kg -1 ?d -1 ,B) dose groups and control group(C,with normalsaline).The rhGH was administered beginning from 3 postburn days(PBDs) and lasted for 20 days.The dynamic changes in the serum levels of TNF-?,IL-6,IL-8 and LPS at different time points were observed.Results When compared with these in C group,the serum levels of TNF-?,IL-6 in A,B groups were decreased,especially in B group with earlier decrease and bigger range(P0.05).Conclusions rhGH might decrease the production of postburn inflammatory mediators.The clinical application of rhGH might be a supplementary measure in preventing and ameliorating postburn SIRS and MODS in severely burned patients.

Objective: To investigate the status of occupational health examination institutions in Zhejiang Province, so as to provide suggestions for quality control of occupational health examination institutions. Methods: The 312 occupational health examination institutions in Zhejiang Province that have completed filing before September 30, 2023 were selected. The comprehensive capability, service quality, technical capability, and information reporting status were surveyed and evaluated through on-site inspection and skill assessment. Results: There were 161 public hospitals (51.60%), 147 private organizations (47.12%), and 4 centers for disease control and prevention (CDCs)/ occupational disease prevention and control institutes (1.28%). The pass rates of comprehensive capability, service quality, technical capability and information reporting were 90.02%, 69.89%, 84.07% and 86.78%, respectively. Among the indicators of comprehensive capability, the compliance rate for staffing was the highest at 95.06%, while the qualification rate of quality control in occupational health examinations was the lowest at 84.83%. Among the indicators of service quality, the compliance rate of the physical examination report format was the highest at 95.83%, while the accuracy rate of the audiometry examination was the lowest at 76.60%. In terms of technical capabilities, the qualification rates for blood lead testing, pneumoconiosis reading, and audiogram diagnostic ability were 87.92%, 89.42% and 75.34%, respectively. In terms of information reporting, the qualification rates for reporting completeness, reporting timeliness, suspected occupational disease reporting timeliness, and reporting accuracy were 89.10%, 81.09%, 96.47% and 80.45%, respectively. Among the three types of institutions, private institutions had the lowest average qualification rates for comprehensive capability, service quality, and technical capability, which were 89.83%, 69.06% and 80.00%, respectively. Conclusions Public hospitals and private organizations were the main types of occupational health examination institutions in Zhejiang Province. However, there were deficiencies in quality control, audiogram examination and diagnosis, and the accuracy of information reporting among occupational health examination institutions.

Objective To investigate the bacteriological monitoring and antibiotic use of invasive infection in patients with burns. Method The index of burn wound、 eschar distribution、 strains of bacteria, bacterial classification、sensitivity and drug resistance were determinated in 100 cases with burns. Results The wound and eschar 382 strain were isolated from the wound and eschar;The wound bacteria 250 strain(65.4%) were significantly higher than that eschar 132 strain (34.6%) (x~2 = 3. 987,P ＜ 0.05); Gram-negative (G -) 227 strain (59. 4%) were significantly higher than that Gram-positive(G +) 155 strain(40. 6%) (x~2 = 3. 887, P ＜ 0.05); Pseudomonas aeruginosa and Enterobacteriaceae in Gram-negative is major strains,while Staphylococcus aureus in Gram-positive is major strains;The Pseudomonas aeruginosa resistance rate(10.38%) was significantly lower than gentamicin(70. 12%) (x~2 =7. 451 ,P＜ 0.01) ;The rate of methicillin-resistant(82. 14%) for Staphylococcus aureus was significantly higher than that of vancomycin(5.35%) (x~2 =7.548 ,P ＜0.01). Conclusion The Gram-negative infection could treat with imipenem,Gram-positive infections could treat with vancomycin for patients with burns.
