Objective To evaluate the clinical curative effect of applying vaccum sealing drainage (VSD) therapy in treating deep partial-thickness burn wound at the initial stage prospectively, and to provide the basis for its clinical application. Methods Twenty-two patients with about 10% TBSA burn of the lower limbs, and in which partial-thickness wound exceeded 1% TBSA in each limb, were admitted to our hospital within 3 hours after burn from May 2009 to March 2010. Wounds in each patient were divided into VSD treatment group (treated with VSD therapy) and control group (treated with 10 g/L silver sulfadia-zine cream) based on the principles of symmetry of location, identical deepness, and similarity in size etc. The amount of water evaporation, the swelling intensity, the status of bacterial colonization, the degree of pain, the healing time, and the quality of healing of wounds in 2 groups were observed and compared. Data were processed with t test and rank-sum test. Results The observation was completed in 21 patients. All of the wounds were treated within 4 hours post burn (PBH). The amount of water evaporation of the normal skin and burn wounds before dressing coverage in VSD treatment group was respectively close to that in control group (with t value respectively 1.310, - 0. 911, P values all above 0.05) ; the amount of water evaporation on the surface of dressing in VSD treatment group [(44. 3 ±3.9) mL·h-1·m-2] was less than that in control group [(66.1 ±6.4) mL · h-1· m-2, t = -11.39, P <0.01]. In VSD treatment group, the circumference of proximal thigh increased (3.48 ±0.35) and (2.51 ±0.21) cm on post burn day (PBD) 3 , 7 as compared with that on PBH 5 , which was respectively smaller than that [(8.02 ± 0.41) , (3. 99 ± 0. 32) cm] in control group (with t value respectively 4. 110, 3. 569, P values all below 0. 01). Positive bacteria' culture rate on PBD 10 of each group was respectively lower than that at admission (with Z value respectively -3.220, -3.870, P values all below 0. 01) , and there was no significant statistical difference between 2 groups at admission or on PBD 10 (with Z value respectively - 0. 894, 0.000, P values all above 0.05). The wound surface in VSD treatment group was weak acidic (pH value 7. 12 ±0.06) on PBD 10,and it was neutral (pH value 7.41 ±0. 13) in control group. The wound pain degree in control group on PBD 1,3,7 was respectively higher than that in VSD treatment group (with t value respectively - 16. 132, -21.230, -16.453, P values all below 0.01). There was no significant statistical difference between 2 groups in healing time of wounds (t =1. 186, P >0.05). The healing quality of wounds in VSD treatment group (100. 00% , 100. 00%) 2 or 3 months after burn was better than that in control group (19. 05% , 85. 71%) (with Z value respectively -11.638, -3. 870, P values all below 0.01). Conclusions Early application of VSD therapy cannot expedite the healing process of deep partial-thickness burn wounds, but it can improve the healing quality. It is one of the effective methods to deal with deep partial-thickness burn wounds, which is worthy of clinical attention and further research. 相似文献

Objective This study was undertaken to observe the change in the local level of angiotensin Ⅱ (Ang Ⅱ) and the expression of its corresponding receptors AT1 and AT2 during wound healing, and explore the possible role of Ang Ⅱ in wound healing . Methods A model of full-thickness cutaneous wound was developed on the back of C57/BL6 mice. Specimens were taken from the wound of each mouse on the day 0, 1, 3, 5, 7, 9, 11, 13 and 15 after wounding. The change in the generation of Ang Ⅱ in wounded tissue during the healing process was detected with ELISA. The proliferation and the apoptosis of cells were detected by bromodeoxyuridine (Brdu) and terminal deoxyuncleotidyl transferase mediated deoxyuridine triphosphate nick end labeling (TUNEL) method in wounded skin during the healing process, respectively. The cellular localization and the mRNA level change of Ang Ⅱ receptors in wounded tissue during healing were detected with immunostaining and RT-PCR. Results Ang Ⅱ produced in wounded skin was increased in the first 7 days to reach the peak, and then gradually decreased during wound healing. BrdU labeling index was increased gradually in the first 7 days to reach the peak, and then gradually decreased during wound healing. The number of TUNEL-positive cells was increased slowly in the first 7 days after wounding. The increase in the number of TUNEL-positive cells was more markedly after epithelization of the wound. In normal mice, AT1 and AT2 receptor were found positively expressed in the whole epidermal layer, while positive expression was only found in the endothelial cells of the capillary vessels within the dermal layer, and positive expression was also found in appendages of the skin, i.e. hair follicle, sweat gland and sebaceous gland respectively. Positive staining signal of both AT1 and AT2 receptors were increased in the first 7 days to reach the peak, then gradually decreased. Expression of AT2R was increased again following the epithelization of wound. The result of RT-PCR showed that the expression of both AT1 and AT2 receptors was detectable, and AT1 receptor was increased in the first 7 days to the peak, and then gradually decreased during wound healing, while AT2 receptor expression reached its peak value on day 7, then gradually decreased, and increased again following the epithelization of wound. Conclusions These results indicate that Ang Ⅱ participate in wound repair and related to remolding in the late stage of wound healing through the change in production of angiotensin Ⅱ and expression of AT1 and AT2 receptors. AT1 receptor might be closely associated with cell proliferation,while AT2 receptor might play a role in cell apoptosis and remolding during wound healing. 相似文献

Objective To compare the clinical effects of minimally invasive reduction through a bone tunnel combined with Jail screwing and those of posterolateral locking plating in the treatment of simple posterolateral tibial plateau fractures. Methods A retrospective analysis was conducted of the data of 48 patients who had been operatively treated and completely followed up at Department of Orthopedics, Suqian Hospital of Nanjing Drum Tower Hospital Group for simple posterolateral tibial plateau fractures from October 2016 to October 2020. There were 26 males and 22 females, aged from 35 to 68 years. They were divided into a minimally invasive group (25 cases subjected to minimally invasive reduction through a bone tunnel combined with Jail screwing) and an incision group (23 cases subjected to posterolateral locking plating) according to their surgical methods. The operation time, incision length, intraoperative blood loss, fracture healing time, cumulative fluoroscopy time, hospital stay and posterior inclination angles of the tibial plateau and Hospital for Special Surgery (HSS) knee function scores at 1, 3, 6, 9, and 12 months after operation were compared between the 2 groups. Complications in the 2 groups of patients were recorded. Results There was no significant difference in the preoperative general data between the 2 groups, showing comparability (P>0.05). The 48 patients were followed up for 12 to 36 months (average 16.5 months). The minimally invasive group was significantly better than the incision group in operation time [(42.6±9.1) min versus (65.7±11.5) min], incision length [(4.0±0.4) cm versus (15.0±1.5) cm], intraoperative blood loss[(22.6±5.8) mL versus (31.5±8.8) mL], hospital stay [(7.6±1.4) d versus (11.1±2.4) d], and HSS score one month after operation [(84.8±1.9) points versus (72.9±4.1) points], but the cumulative fluoroscopy time in the incision group [(4.1±1.4) s]was significantly less than that in the minimally invasive group [(22.3±4.2) s] (P<0.05). There were no significant differences in fracture healing time, HSS scores at 3, 6, 9, or 12 months after operation, or posterior inclination angle of the tibial plateau between the 2 groups (P>0.05). There were no such complications as wound infection, vascular injury, internal fixation failure, nonunion or malunion of fractures in either of the 2 groups. Two cases in the incision group presented with symptoms of common peroneal nerve injury but recovered 3 months after operation. Conclusions Although both minimally invasive reduction through a bone tunnel combined with Jail screwing and posterolateral locking plating can achieve satisfactory outcomes in the treatment of simple posterolateral tibial plateau fractures, the minimally invasive technique is preferable because it shows the advantages of a smaller incision, less bleeding, shorter operation time, a lower operation risk, quicker postoperative recovery and shorter hospital stay. © 2022 Chinese Journal of Orthopaedic Trauma.

Objective To report clinical efficacy of vacuum sealing drainage(VSD)and external fixation in the treatment of tibiofibular fractures of Gustilo type Ⅲ. Methods From October 2006 to November 2009,19 cases of Gustilo type Ⅲ tibiofibular fracture were treated in our department.They were 14men and 5 women,with an average age of 30.1 years(from 17 to 62 years).There were 9 cases of type ⅢA,8 cases of Type ⅢB 2 cases of typeⅢC.After emergency debridement,all the fractures were fixed with an extemal fixator following indirect reduction.The wounds were sealed with VSD.When the wounds were clean and granulation appeared,they were repaired by direct suture(5 cases),split-thickness skin graft(9 cases)and flap transposition(5 cases). Results The 19 cases were followed up for 12 to 24 months,with an average of 16.3 months.A11 the wounds were closed'after VSD for 5 to 17 days.Wound infection occurred in 2 cases and was finally repaired by flap transposition following repeated debridement and VSD.The fractures healed after 4 to 10 months(average,5.6 months). Conclusion External fixation combined with VSD is a simple and effective treatment for tibiofibular fractures of Gustilo type Ⅲ.because it can provide not only rapid fixation but also early wound sealing to facilitate fracture healing and reduce incidence of complications. 相似文献

目的 观察荷负电气溶胶治疗对大鼠烫伤创面愈合过程中白细胞介素(IL)-8、IL-10表达的影响,探讨荷负电气溶胶治疗促进创面愈合的作用机制.方法 制作SD大鼠深Ⅱ度烫伤模型,采用分组对照方法,将40只鼠随机分为治疗组(n1=20)和对照组(n2=20).治疗组应用荷负电气溶胶治疗,每次1.5 h,每天2次,直至创面愈合;对照组不作荷负电气溶胶治疗.伤后第1~11天分别取创面标本制作切片,采用免疫组织化学和图像分析方法,检测创面愈合过程中IL-8和IL-10表达水平.结果 创面平均愈合时间治疗组为(7.00±1.15)d,对照组为(9.00±1.34)d,治疗组创面愈合时间明显提前(P<0.01).免疫组织化学显示,两组IL-8均在伤后第1天开始表达.主要位于多核粒细胞和单核细胞;第3天表达明显增多达高峰,并见大量成纤维细胞表达,治疗组的峰值明显低于对照组,差异有统计学意义(P<0.01),第5~11天表达水平迅速下降.两组IL-10伤后第1天在淋巴细胞和单核细胞均有表达;第3天开始有角质细胞表达并达高峰,第5~11天表达水平缓慢下降,但治疗组要明显高于对照组,第3~11天差异有统计学意义(P<0.01).结论 荷负电气溶胶治疗能有效抑制创面IL-8的表达及促进IL-10的表达,缩短炎症进程,从而加速创面愈合.Abstract: Objective To discuss the influence of aerosol bioelectricity on the expression of interleukin (IL) -8 and IL-10 in wound healing of burned rats. Methods The deep Ⅱ degree scalding models were established in Sprague Dawley (SD) rats. Rats were randomly divided into experimental group (n1 =20) and control group (n2 =20). The rats in experimental group were treated with aerosol bioelectricity.Samples were collected at the first to eleventh day post-scalding. Immunohistochemistry and image analysis methods were conducted to examine the expression of IL-8 and IL-10 in both experimental and control groups. Results The average wound healing time in experimental group was 7. 00 ± 1. 15 days, and that in control group was 9. 00 ± 1. 34 days. IL-8 and IL-10 were observed mainly in polylmorphonuclear and mononuclear cells in both experimental and control groups on the 1 st day. On the third day, fibroblasts abounded, IL-8 expression was increased evidently and reached a peak. The peak value (6. 73 ± 1. 36) in experimental group was lower significantly than that in control group ( 2. 85 ± 0. 72, P < 0. 01). From the 5th to 11th day, IL-8 expression was declined rapidly. IL-10 was expressed in keratode cells and had the peak value in experimental group (1. 24 ±0. 15) and control group (5. 69 ± 1. 32) on the 3rd day. IL-10 expression was declined gradually from the 5th to 11th days. The expression level of IL-10 in experimental group was significantly higher than in control group from the 3rd day to 11th days post-scalding (P<0. 01). On the 3rd day, both IL-8 and IL-10 in experimental and control groups were expressed abundantly , and there was negative relationship between them (r = - 0. 862, P < 0. 01). Conclusion Aerosol bioelectricity can indicate active cells proliferation through down-regulating the expression of IL-8 and up-regulating the expression of IL-10, accelerating burned wound healing. 相似文献

Animal study on expression of laminin and fibronectin in cornea during wound healing following alkali burn 总被引:1,自引:0,他引:1
Objective:To observe the expression of laminin and fibronectin in alkali-burned corneas in rats.Methods:A total of 18 normal Wistar rats were randomly divided into 6 groups(n=3 in each group).For each rat, one eye was injured by alkali burn,the other one was taken as the normal control.Then all the corneas were surgically removed and the expression of laminin and fibronectin was observed with immunohistochemistry respectively at 7 hours,1 day,3 days, 7 days,14 days and 28 days after alkali burn.Results:Compared with that of the normal controls, the expression of laminin and fibronectin of the burned eyes was dramatically higher at 7 hours, reached peak at 14 days and decreased to the normal level at 28 days after alkali burn.Conclusions:In the process of wound healing after alkali burn, the expression of laminin and fibronectin increases dramatically, which suggests that laminin and fibronectin may participate in the process of corneal wound healing. 相似文献
