OBJECTIVETo investigate the influence of recombinant human growth hormone (rhGH) on the mortality of the patients with severe burns.

METHODSIn a prospective multi-center randomized clinical trial, 207 adult patients with severe burns were enrolled in the study, and they were randomly divided into treatment (T, with subcutaneous injection of rhGH) and placebo control (C, with subcutaneous injection of same amount of isotonic saline) groups. The mortality, incidence of hyperglycemia and sepsis in the two groups were observed.

RESULTSThe mortality rate in T group was 0.89% as compared with 5.26% in the C group (P >0.05). Hyperglycemia (blood glucose level over 10 mmol/L) was present in 36.61% of patients in T group but 18.95% in C group (P <0.01). There was no difference in the incidence of sepsis between the two groups (P > 0.05).

CONCLUSIONThe application of rhGH in appropriate dosage in adult patients with severe burns could be safe, but blood glucose level should be monitored during the administration.

OBJECTIVETo observe the effects of Dioscornin Tablet (DT) containing serum on nuclear factor of kappa B (NF-kappaB) p65, signal transducer and activator of transcription 3 (STAT3), and vascular endothelial growth factor (VEGF) mRNA expressions in rats' synovial cell strain 364 (RSC-364) induced by interleukin-17 (IL-17) and tumor necrosis factor-alpha (TNF-alpha), and to investigate the underlying mechanisms for DT to inhibit angiogenesis of rheumatoid arthritis (RA).

METHODSIn this experiment, the vehicle control group, the cell model group, the DT containing serum group, and the positive control group (Tripterygium containing serum) were set up. The DT containing serum and the Tripterygium containing serum were prepared. The RA cell model was established by IL-17 combined TNF-alpha induced injury in RSC-364. The RA cells were intervened by DT containing serum and Tripterygium containing serum respectively. The DNA binding activity of NF-kappaB p65 was detected using TransAM NF-kappaB p65. The expression of STAT3 was observed using Western blot. The VEGF mRNA expressions were detected by real-time quantitative PCR.

RESULTSCompared with the vehicle control group, the NF-kappaB p65 activity, the expressions of STAT3 and VEGF mRNA increased significantly in RSC-364 induced by IL-17 +TNF-alpha (P < 0.01, P < 0.05). Compared with the model group, the NF-kappaB p65 activity, the expressions of STAT3 and VEGF mRNA decreased significantly in the DT containing serum group and the positive control group (P < 0.01, P < 0.05). There was no statistical difference between the two groups (P > 0.05).

CONCLUSIONDT inhibited the VEGF mRNA expression through inhibiting the NF-kappaB p65 activity and the STAT3 protein expression in the Janus kinase (JAK)-signal transducer and activating transcription factor pathway, thus inhibiting the angiogenesis of RA.

OBJECTIVETo investigate the effects of recombinant human growth hormone (rhGH) on the changes in serum insulin-like growth factor-I (IGF-I), IGF binding protein 3 (IGFBP-3) and blood sugar in severely burned patients, so as to validate the optimal time of rhGH administration.

METHODSForty severely burned patients were enrolled in the study and were randomly divided into control (C), treatment 1 (rhGH given from 7 - 9 PBD, T1) and treatment 2 (rhGH from 10 - 14 PBD, T2) groups. The dynamic changes in serum IGF-I, IGFBP-3 and blood sugar on the 1, 3, 5, 7, 10, 14 and 21 PBDs in all 3 groups of burn patients were determined, analyzed and compared with one another.

RESULTSThe serum IGF-I, IGFBP-3 and blood sugar levels in T1 and T2 groups were higher than those in C group after the use of rhGH, especially the IGFBP-3 and blood sugar (P < 0.05). There was no difference of all the indices between T1 and T2 groups.

CONCLUSIONIt might be optimal to give rhGH to severely burned patients during 7-9 PBDs.

OBJECTIVETo investigate the status of nutritional support therapy in moderate and severe burn patients.

METHODSThe burn patients with age over 16 y and burn area larger than 20% TBSA were enrolled in the retrospective study. According to length of stay, all patients were divided into the first period (271 cases, was from 1994 to 2001 year), and second period (273 cases, from 2002 to 2007 year), and they were subdivided into a (20% - 30% TBSA), b (31% - 50% TBSA), c (51% - 70% TBSA), d (larger than 70% TBSA) groups. The death rate and ratio of nutritional support therapy were compared. The change in albumin and other indices (including side-effects, complication, etc) were analyzed in each group in second period.

RESULTSThere were similar in general conditions in both groups, however, some were obvious difference in two periods between nutritional support therapy rate (74.17% in first period vs 85.35% in second period, P < 0.01), and the ratio of parenteral nutrition to enteral nutrition (1.5:1.0 in first period, 1.0:1.5 in second period, P < 0.01). There were also significant differences in albumin levels among each group in second period on 4, 7, 14 days after burn (P < 0.05). In the second period, parenteral nutrition preparation was mostly delivered through central vein in the form of "all-in-one", among them 62 cases of positive catheter cultures were found. Enteral nutrition was delivered by oral route in 108 cases, naso-gastric or naso-enteric tubes with pump in 165 cases. 27 cases with severe gastrointestinal complications and 2 cases with inhalation pneumonia occurred.

CONCLUSIONThe ratio of parenteral nutrition and enteral nutrition in burn patients was higher in our ward than average level in China. There is still a long way ahead to optimize nutritional therapy.

OBJECTIVETo investigate the influence of recombinant human growth hormone (rhGH) on body fluid compartments and water-sodium retention in severe burn patients.

METHODSThirty adult patients with severe burn were divided into treatment (T) and control (C) groups by block randomized design. Patients in both groups were subcutaneously injected with same amount of rhGH (12 IU/d) or isotonic saline during 7 - 21 post burn day (PBD). The total body water (TBW), intracellular water (ICW), extracellular water (ECW) were measured by bioelectrical impedance analysis (BIA) on 7, 14, 21 PBD. The 24 h urinary output of Na+ was determined by ion selective electrode method (ISE).

RESULTSThere were no significant difference in levels of TBW, ICW, ECW and 24 h urinary output of Na+ between two groups on 7, 14, 21 PBD (P > 0.05). No difference in results was found between groups at different time points (P > 0.05). After the data were analyzed, the level of TBW (36 +/- 6 L), ICW (21 +/- 4 L) on 21 PBD were evidently lower than those on 7 PBD (38 +/- 6 L, 23 +/- 7 L, P < 0.01).

CONCLUSIONThe level of ICW and TBW in severe burn patients decreased along with the time. Proper dosage of rhGH has no significant effect on body fluid compartments and water-sodium retention.

Relevant data including diagnosis and treatment model, operation situation, etc. are analyzed in our wound care center and compared with abroad based-on literature retrieval, to find out a suitable way for setting up wound care centers in our country. Wound care center with mode of multidisciplinary cooperation that is "specialist-oriented" was established in our hospital, mirroring the experience of foreign wound care centers. The investigation showed the demands of patients could be met, their psychological and economic pressures as well as social burden might be greatly relieved in our center. For an example, we achieved our purpose readily by setting up a clinical pathway of diabetic foot according to the features of our hospital. The model of multidisciplinary cooperation, with minor adjustments, may be applicable for wound care centers at home and abroad. Our wound care center will establish better system of diagnosis and treatment to conform to the situation in our country.

OBJECTIVETo establish a novel Myc gene transgenic mouse model for spontaneously forming B-lymphoma and assessing its tumorigenesis potential.

METHODSFreshly isolated hematopoietic progenitor cells served as the target for Myc gene transfer mediated by a retrovirus vector. These cells were engrafted into C57BL/6 mice with (60)Co-gamma ray radiation in advance. Tumor latency was measured and the tumor loaded mice were followed for survival time. Tumor was identified with histology and immunostaining. The exogenous Myc gene was detected by Western blot (in liver, spleen, tumor tissue) and flow cytometry (FCM) \[in bone marrow (BM)\].

RESULTSMice BM-infected with mutant Myc gene more readily gave rise to B-cell lymphomas than those infected with wild type Myc gene did Myc gene was expressed highly in BM and tumor tissues but not in liver and spleen.

CONCLUSIONOur model will be a tool in assessing the transforming potential of Myc mutants and in studying cooperation between Myc and other oncogenes. Mutant Myc is more effective than wild-type Myc in promoting B cell lymphomagenesis in mice.
