目的 探讨院外延续性护理联合院内心理指导对重症烧伤患者创伤应激的影响。方法 选取2020年6月—2022年6月南开大学附属医院（天津市第四医院）重症烧伤科收治的86例重度烧伤患者为研究对象,应用随机数字表法将患者分为观察组与对照组,每组各43例。对照组采取常规护理,观察组在常规护理基础上增加院外延续性护理联合院内心理指导,评估患者的创伤应激指标[血清肿瘤坏死因子α（TNF-α）、白细胞介素6（IL-6）、β-内啡肽（β-ep）]、心理韧性程度、应对行为、创伤后成长水平,并分析患者创伤应激与心理韧性的相关性。结果 干预前,两组的TNF-α、IL-6、β-ep水平比较差异无统计学意义（P>0.05）;干预后,两组创伤应激相关指标水平均下降,且观察组降低幅度更大（P<0.05）。干预后,两组患者乐观性、力量性、坚韧性相关中文版创伤后成长评定量表（C-PTGI）评分均升高,且观察组更高（P<0.05）;Pearson相关性分析显示,TNF-α、IL-6、β-ep等创伤应激指标水平与心理韧性水平呈负相关（P<0.05）;干预后,两组患者积极应对特质应对方式问卷（TCSQ）评分均升高,观察组高于对照组,人消极应对评分均降低,观察组低于对照组（P<0.05）;干预后,两组患者人际关系、精神变化、生活欣赏、个人力量、新的可能相关C-PTGI评分分量表得分均升高,观察组高于对照组（P<0.05）。结论 对重度烧伤患者采取院外延续性护理联合院内心理指导能够降低患者的创伤后应激水平、消极应对评分,提升患者心理韧性程度、创伤后成长水平以及积极应对评分,且创伤后应激水平与心理韧性水平呈负相关。

Objective To explore the effect of out-hospital continuous nursing combined with in-hospital psychological guidance on traumatic stress in severe burn patients．Methods A total of 86 patients with severe burn treated in the Affiliated Hospital of Nankai University（Tianjin Fourth Hospital）from June 2020 to June 2022 were selected as the research objects．The patients were divided into observation group and control group by random number table method,with 43 cases in each group．The control group received routine care,and the observation group was supplemented with out-hospital continuous nursing and in-hospital psychological guidance on the basis of routine care．The traumatic stress indexes [serum tumor necrosis factor-α（TNF-α）,interleukin-6（IL-6）,β-endorphin（β-ep）],psychological toughness,coping behavior and post-traumatic growth level of the patients were evaluated．The correlation between traumatic stress and mental toughness was analyzed．Results Before intervention,the levels of TNF-α,IL-6 and β-ep were not significantly different between the two groups（P>0.05）．After intervention,the levels of traumatic stress-related indicators were decreased between the two groups,and the reduction was greater in the observation group（P<0.05）．After intervention,C-PTGI scores related to optimism,strength and fortitude were increased in both groups,which were higher in observation group（P<0.05）．Pearson correlation analysis showed that the levels of TNF-α,IL-6,β-ep and other traumatic stress indexes were significantly negatively correlated with the levels of mental toughness（P<0.05）．After intervention,the positive coping TCSQ scores of both groups were increased,the observation group was higher,and the negative coping scores were decreased,while the observation group was lower（P<0.05）．After the intervention,the scores of interpersonal relationships,mental changes,life appreciation,personal strength,and new possibly relevant C-PTGI score subscale were increased in both groups,and higher in the observation group（P<0.05）．Conclusions The combination of out-hospital continuous nursing and in-hospital psychological guidance for severe burn patients can reduce the level of post-traumatic stress and negative response score of patients,and improve the level of mental toughness,post-traumatic growth and positive score of patients,and the level of post-traumatic stress is significantly negatively correlated with the level of mental toughness．

严重烧伤后患者免疫功能的失调,易导致创面感染、全身炎症反应综合征、脓毒症、感染性休克等并发症,增加患者病死率。免疫细胞功能适度的活化将有助于烧伤患者抵御外界病原体的侵袭、促进创面的愈合,但功能过度激活或者功能低下,则会引发一系列严重的后果。本文旨在归纳严重烧伤后中性粒细胞、单核/巨噬细胞、肥大细胞、NK细胞及T淋巴细胞等免疫细胞的功能变化与炎症反应之间的关系,为完善烧伤患者诊疗、减少并发症、改善预后提供新的思路。

The imbalance of immune function in severely burned patients can easily lead to wound infection,systemic inflammatory response syndrome,sepsis,septic shock and other complications,which increase the mortality of patients. Moderate activation of immune cell function will help burned patients to resist the invasion of external pathogens and promote wound healing,but excessive activation or low function can lead to a series of serious consequences. The purpose of this paper is to summarize the relationship between the functional changes of immune cells such as neutrophils,monocytes/macrophages,mast cells,NK cells,T lymphocytes and inflammatory reaction after severe burns,and to provide new ideas for improving the diagnosis and treatment of burned patients,reducing complications and improving the prognosis.

目的 探讨烧伤后瘢痕整形患者康复期创伤后成长及情绪调节策略及干预效果。方法 选择2021年10月—2023年6月期间我院接收的55例烧伤后瘢痕整形患者作为研究对象,采用随机数字表法分为2组,对照组27例采取常规康复护理干预,观察组28例实施针对性评估及护理干预,评价2组创伤后成长特征、情绪调节策略、应对方式。结果 干预后,观察组自我转变、个人力量、人生感悟、新的可能性和与他人关系等评分均高于对照组（均P<0.05）。护理干预后观察组情绪调节评分（ERQ）优于对照组,其中认知重评评分更高、表达抑制评分更低,组间比较差异有统计学意义（均P<0.05）。护理干预后应对方式评分优于对照组,其中回避、屈服评分更低,面对评分更高（均P<0.05）。结论 基于康复期创伤后成长及情绪调节现状实施针对性护理干预可促进烧伤后瘢痕整形患者减轻创伤感受,能够以积极的情绪应对康复期,改善情绪状态。

Objective To observe effect of the recombinant bovine basic fibroblast growth factor in the treatment of superficial Ⅱ degree burn wounds. Methods Ninety cases of small area of superficial Ⅱ degree burn wounds were randomly divided into 2 groups: recombinant bovine basic fibroblast growth factor group(rb-bFGF) and control group (Iodophor gauze group). The wound healing time,patient pain, long-term hyperpigmentation and scar chance of proliferation were observed. Results The effect of rb-bFGF treatment group was better than that of control group. The healing time of the treatment group was (8.56 ± 2.51)d, it was shorter than that of the control group (12.42±2.13)d(P<0.01). The average healing time was 3~5 days, it was ahead of the control group; Compared to the control group, the rb-bFGF group had less pain (VAS scores were: 1.66±0.05 and 3.25±0.12,P<0.01); Some patients were followed up a year later, we found that the treatment group long-term pigmentation was lighter, scar chance of proliferation was lower. Conclusion Application of rb-bFGF in the treatment of small area of shallow Ⅱ degree of burns may shorten the wound healing time. As effective promotion of burn wound healing, it may reduce the pain when dressing, reduce long-term pigmentation and scarring rate.

目的 研究紫虎烧伤膏的抑菌作用强度。方法 采用体外试验测定紫虎烧伤膏的MIC和MBC,纸片法比较紫虎烧伤膏和湿润烧伤膏对不同代表性菌种抑菌圈大小;动物实验比较紫虎烧伤膏和湿润烧伤膏用于大鼠Ⅱ度烫伤模型24 h,48 h后创面菌落计数。结果 紫虎烧伤膏对金黄色葡萄球菌的MIC(Minimum inhibitory concentration)为8 mg/mL,MBC (Minimum bactericidal concentration)32 mg/mL;对铜绿假单胞菌的MIC为16 mg/mL,MBC32 mg/mL;对大肠杆菌的MIC为16 mg/mL,MBC64 mg/mL。抑菌圈试验结果显示,紫虎烧伤膏和湿润烧伤膏没有显著性差异。动物实验表明,紫虎烧伤膏和湿润烧伤膏均有不同程度的抑制大鼠Ⅱ度烫伤局部细菌的作用。紫虎烧伤膏的作用更强。用药时间越长,抑菌效果越明显。结论 紫虎烧伤膏能够有效抑制Ⅱ度烧烫伤局部细菌,防止烧烫伤创面感染,保护创面,从而起到治疗Ⅱ度烫伤的作用。

Objective To study the antibacterial effect of the purple tiger burn ointment. Methods The MIC and MBC were determined by using in vitro test. Comparison of the inhibition zone size of the different representative strains of the purple tiger burn ointment and the moist burn ointment were made, the animal experiment was used to compare the colony count of the wound of the rat model of second degree scald after 24 h, 48 h with the purple tiger burn ointment and the moist burn ointment. Results MIC(Minimum inhibitory concentration)of purple tiger burn ointment on Staphylococcus aureus was 8 mg/mL, MBC(Minimum bactericidal concentration ) of purple tiger burn ointment on Staphylococcus aureus was 32 mg/mL; MIC of purple tiger burn ointment on Pseudomonas aeruginosa was 16 mg/mL, MBC of purple tiger burn ointment on Pseudomonas aeruginosa was 32 mg/mL, MIC of purple tiger burn ointment on Escherichia coli was 16 mg/mL, MBC of purple tiger burn ointment on Escherichia coli was 64 mg/mL. The results showed that there was no significant difference between the purple tiger burn ointment and the moist burn ointment. Animal experiments showed that the purple tiger burn ointment and the moist burn ointment had different degrees of inhibition of the role of local bacteria in the second degree scald in rats. Purple tiger burn cream showed stronger function. The longer the time took, the more obvious the antibacterial effect was. Conclusion The purple tiger burn ointment can effectively inhibit the second degree burn of local bacteria, prevent the wound infection and protect the wound, so as to play a role in the treatment of second degree scald.
