OBJECTIVE To study the characteristics and management of fungal infection in severely burn patients.METHODS The clinical data of 51 severely burn patients with fungal infection in our department from 2000 to 2004 were analyzed.RESULTS The infection rate in total 213 severely burn patients was 23.72%.Candidiasis was the most frequent type in fungal infection accounting for 93.98%.The risk factors for fungal infection were the(severity) of burn,tracheal intubations,body catheterizations,long-term use of broad-spectrum antibiotic and(hospitalization).CONCLUSIONS Development and the types of fungi in severely burn patients with fungal infection have their own characterizations and inducing factors.it is important to eluminate the susceptible factors and provide early diagnosis and treatment.

Objective To investigate the administration of antibiotics in the treatment of infection of burns based on bacteriological surveillance from burn wound.Methods A retrospective analysis of bacterial culture and drug-sensitivity results from burn wound and subeschar tissues in 581 patients during 1999 to 2004 was carried out.Results Eight hundred and eighty-seven strains of bacteria were isolated from burn wound and subeschar tissues in 581 patients,among which 481 strains were gram negative(54.23%),and 406 strains were gram positive(45.77%).Among the bacteria of gram negative,the most majority was Pseudomonas and then was the Enterobacteriaceae.Among the bacteria of gram positive,Staphylcoccus aureus was the majority,and MRSA accounted for 71.48% in the Staphylcoccus aureus.The resistance of Pseudomonas to Netilmicin was decreased from 20.1% to 4.9%,and the resistance of Enterobacteriaceae to Imipenem was still in a low level.All bacteria of gram positive were sensitive to Vancomycin.Conclusion The majority of the bacteria of burn infection is gram negative.The isolated bacteria show multiple resistance to antibiotic.The analysis of bacteria from burn wound and resistance of bacteria to antibiotic is very important to experiential treatment of antibiotic for burn infection.

Objective To investigate of the tissue TGF-β changes at early stage of hypertrophic scar formation and the value of scar blisters in hypertrophic scar.Methods The TGF-β1 content in the blister fluid and the blood were quantified with ELISA,patients(n=15)with hypertrophy scar after depth burn were included,three time point(each n=5)on early　stage(<3 months)of hypertrophy scar formationwere monitored.and normal skin blister fluid and the blood(n=5)was used as control.Results The serum TGF-β1 in the both hypertrophic scar patients and normal skin group was not elevated(P>0.01),the TGF-β1 in the blister of normal skin was also not elevated(P>0.01),but TGF-β1 level in the scarblisters hypertrophic scar was elevated significantly[<60 d(158.5±69.8)pg/L,60-90 d,(181.1±40.1)pg/L,>90 d,(534.4±125.9)pg/L,P<0.01] and higher than the normal skin blister and the blood(P<15.6 pg/L.P<0.01),the increased TGF-β1 1evel in the hypertrophic scar blisters were persisted for at least three months.the TGF-β1 level of scar blister on the 3th month of hypertrophic scar formation reached a peak [(534.4±125.9)pg/L,P<0.01].Conclusions The data in this study indicates that TGF-β production at the early stage of hypertrophic scar formation is increased and may play an important role in scar formation;scar blisters is a valuable approach in hypertrophic scar study.

OBJECTIVE: To test the reliability and validity of Health Scale of Traditional Chinese Medicine (HSTCM) by means of questionnaires. METHODS: A cross-sectional survey was conducted at Liwan Community of Guangzhou, Old People's Home in Guangzhou and Outpatient Department of the Second Affiliated Hospital of Guangzhou University of Chinese Medicine. A total of 652 Chinese individuals (over 18 years old) were assessed with the 88-item version of HSTCM and World Health Organization Quality of Life Measure-Abbreviated Version (WHOQOL-BREF), which were randomly delivered to them. Some socioeconomic characteristics were registered. RESULTS: A test-retest reliability (15-day interval) was found among the 76 persons who completed the questionnaires by themselves. Intra-class correlation coefficient (ICC) was 0.93. Associated 95% confidence interval (CI) was 0.89-0.96. Split-half reliability was 0.79. Inter-investigator reliability (0.93) was also good, and the ICC of HSTCM was 0.90 (95%CI 0.67-0.97). The correlation between HSTCM and WHOQOL-BREF was -0.66. The correlations of HSTCM and questionnaire deliver order, investigator, interview date and interview time were 0.06, -0.12, -0.17 and 0.20 respectively. The correlation between HSTCM and self-rated health (0.46) was greater than that between HSTCM and chronic illness (0.28). Divided by individuals with or without chronic illness, area under the ROC (receiver operator characteristic) curve for HSTCM was 0.67 (95%CI 0.63-0.71). CONCLUSION: It indicates that the HSTCM is conceptually valid with satisfactory psychometric properties and forms a basis for further applications in clinical research of traditional or integrative medicine.

OBJECTIVETo explore the effects of recombinant human growth hormone (rhGH) on the serum levels of cytokines in severely burned patients.

METHODSThirty-six burn patients were enrolled in the study and were randomly divided into 3 groups according to the rhGH dosage used, i.e. small (0.3 IU.kg(-1).d(-1), A), large (0.6 IU.kg(-1).d(-1), B) dose groups and control group (C, with normal saline). The rhGH was administered beginning from 3 postburn days (PBDs) and lasted for 20 days. The dynamic changes in the serum levels of TNFalpha, IL-6, IL-8 and LPS at different time points were observed.

RESULTSWhen compared with those in C group, the serum levels of TNFalpha, IL-6 in A, B groups were decreased, especially in B group with earlier decrease and bigger range (P < 0.01). Simultaneously, the serum LPS level was decreased accordingly with evident positive correlation with the change in those cytokines (r = 0.9723, P < 0.01). But there was no obvious difference in serum IL-8 level among A, B and C groups (P > 0.05).

CONCLUSIONrhGH might decrease the production of postburn inflammatory mediators, especially in higher dose in dose-dependent manner for some degree. 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 HPV vaccine hesitancy and influencing factors among parents of primary and secondary schools in Guangyuan, and to provide scientific countermeasures for reducing the hesitancy rate of HPV vaccine in parents. Methods Using stratified multi-stage cluster random sampling, 1,018 parents of girls in primary and secondary schools in Guangyuan were selected for a questionnaire survey from March to July 2021. The data were analyzed by Chi-square test and multivariate logistic regression model. Results The hesitancy rate of HPV vaccine in parents was 42.95%. Multivariate logistic regression analysis showed that families with low economic income, parents who believed that HPV vaccination would have long-term side effects, and be unsafe and expensive, and parents who concerned with the effect of HPV vaccine on the prevention of cervical cancer and insufficient supply of first doses of vaccine, had positive effects on HPV vaccine hesitancy (OR = 2.02, 1.44, 3.13, 1.53, 3.76, and 2.43, respectively, P < 0.05). Conclusion HPV vaccine hesitancy rate is high among parents of primary and secondary schools in Guangyuan. It is necessary to fully promote school education and increase the publicity of HPV vaccine to improve parents' awareness of HPV vaccine. Government departments need to make an overall plan to reduce vaccine costs and ensure sufficient vaccine quantity, so as to reduce parents' hesitation to vaccinate their children with HPV vaccine.
