The influence of recombinant human growth hormones on the systemic metabolism after severe burn / 中华烧伤杂志

<p><b>OBJECTIVE</b>To explore the influence of recombinant human growth hormones (rhGH) postburn systemic metabolism.</p><p><b>METHODS</b>Twenty-four burn patients were randomly and equally divided into treatment and control groups. Same amount of rhGH (9 U/d) or isotonic saline was injected subcutaneously to respective patients during 3 approximately 17 postburn days (PBDs). Blood samples were harvested at 3, 10 and 17 PBDs for the determination of serum growth hormone, insulin-like growth factor (IGF-1), insulin-like growth factor binding protein-3 (IGFBP-3), serum proteins, plasma insulin, plasma glucagons and blood glucose, which were then compared and analyzed between two the groups.</p><p><b>RESULTS</b>The serum levels of GH, IGF-1, IGFBP-3, serum prealbumin and transferrin in rhGH treatment group were evidently higher than those in control groups at 10 and 17 PBDs (P < 0.05 approximately 0.01). But there was no obvious difference in serum albumin, plasma insulin, glucagon and blood glucose (P > 0.05).</p><p><b>CONCLUSION</b>Small dose of rhGH could promote systemic protein synthesis with no side effects on blood glucose levels.</p>

Changes of cellular immunity in patients with hypertrophic sear / 中华医学美学美容杂志

Objective To analyse the changes of T lymphocytes and its subset in patients with scar hypertrophy. Methods In 6 keloid, 14 hypertrophic scar patients and 10 normal control, peripheral blood T lymphocytes (PBTL) and its subset were analysed with flow cytometry (FCM). Lymphocytic proliferation responsed to Con A stimulation in vitro lymphocytic culture system were performed and lymphocytic proliferation activity were assayed by the measurement of 3H TdR incorporation. Results The percent of CD3 +,CD4 +,CD8 + and ratio of CD4 +/CD8 + in PBTL of keloid patients were 78.6 %, 49.7 %, 23.5 % and 2.4, and in hypertrophic scar patients group were 68.9 %, 47.6 %, 26.6 % and 2.2, in normal control group were 69.2 %, 37.2 %, 30.9 % and 1.9, respectively. Lymphocytic proliferation activity expressed as proliferation stimulation index were 17.4,15.9 and 8.7 respectively in keloid, hypertrophic scar and normal group. The level of CD4 +?CD4 +/CD8 + and lymphocytic proliferation stimulative index were all significantly higher in both keloid and hypertrophic scar patients than that in normal control. Conclusion Aberrant immunologic function may play an important role in the pathogenesis of scar.

Transportation of server burn patients with shock / 解放军医学杂志

Objective To assess the possibility of the transportation of patients with critical burns during shock stage. Method Data on 9 groups (63 cases) of critical burn patients, who were transferred to burn unit in 48 hours after injury, were collected and analyzed during recent 5 years. Results All of the 63 patients were transported stably and successfully. Sixty-one of them were cured and 2 were died of multiple system organ failure at the 9th and the 19th day post burn, respectively. Conclusions On principle, anti-shock treatment of the critical burn patients should be initiated immediately on the spot before transportation. For the hospitals with limited medical resources, however, it is necessary to transfer the patients to the specialized burn units with speedy and smooth vehicles after rapid fluid resuscitation, and fluid transfusion must be carried out simultaneously during transportation.
