Abstract
Objective: To investigate the surgical treatment methods of femoral artery pseudoaneurysm combined with infectious wounds and to evaluate the clinical effects. Methods: The retrospective observational research method was used. Twelve patients with femoral artery pseudoaneurysm combined with infectious wounds who met the inclusion criteria were admitted to Nanjing University of Chinese Medicine Wuxi Integrated Traditional Chinese and Western Medicine Hospital (Affiliated Hospital of Jiangnan University) from October 2014 to September 2022, including 6 males and 6 females, aged from 46 to 78 years. In the primary operation, debridement, tumor resection, and artery suture/venous grafting to repair the artery/artery ligation were performed, and the wound area after tumor resection ranged from 4.0 cm×1.5 cm to 12.0 cm×6.5 cm. Wounds that could be sutured were treated with tension reduction suture and extracutaneous continuous vacuum sealing drainage (VSD), while large wounds that could not be sutured were treated with VSD to control infection. In the secondary operation, tension reduction suture was performed to repair the wounds that could be sutured; large wounds were repaired with adjacent translocated flaps with area of 9.0 cm×5.0 cm to 15.0 cm×7.0 cm. Additionally, when the length of the exposed femoral artery was equal to or over 3.0 cm, the wounds were repaired with additional rectus femoris muscle flap with length of 15.0 to 18.0 cm. The donor areas of the flaps were directly sutured. The wound with artery ligation was treated with stamp skin grafting and continuous VSD. The bacterial culture results of the wound exudate samples on admission were recorded. The intraoperative blood loss, the location of femoral artery rupture, the artery treatment method, and the wound repair method in the primary operation were recorded, and the durations of catheter lavage, catheter drainage, and VSD treatment, and the drainage volume after the operation were recorded. The repair method of wounds in the secondary operation, the durations of catheter drainage and VSD treatment, and the total drainage volume after the operation were recorded. The survivals of flap/muscle flap/stamp skin grafts were observed, and the wound healing time was recorded. Follow-up after discharge was performed to evaluate the quality of wound healing and the walking function and to check whether the pulsatile mass disappeared. B-ultrasound or computed tomography angiography (CTA) was performed again to observe potential pseudoaneurysm recurrence and evaluate the patency of blood flow of the femoral artery. Results: The bacterial culture results of wound exudate samples of all the patients were positive on admission. The blood loss was 150 to 750 mL in the primary operation. The arterial ruptures were located in the femoral artery in 8 cases, in the external iliac artery in 2 cases, and in the femoral arteriovenous fistula in 2 cases. Six cases received direct artery suture, 4 cases received autologous great saphenous vein grafting to repair the artery, 1 case received autologous great saphenous vein bypass surgery, and 1 case received artery ligation. The primary wound suture was performed in 4 cases, along with catheter lavage for 3 to 5 days, catheter drainage for 4 to 6 days, VSD treatment for 5 to 7 days, and a total drainage volume of 80 to 450 mL after the surgery. In the secondary operation, the wounds were sutured directly in 3 cases along with catheter drainage for 2 to 3 days, the wound was repaired with scalp stamp skin graft and VSD treatment for 5 days in 1 case, the wounds were repaired with adjacent translocated flaps in 2 cases with catheter drainage for 2 to 3 days, and the wounds were repaired with rectus femoris muscle flaps+adjacent translocated flaps in 2 cases with catheter drainage for 3 to 5 days . The total drainage volume after the secondary operation ranged from 150 to 400 mL. All the skin flaps/muscle flaps/skin grafts survived after operation. The wound healing time ranged from 15 to 36 days after the primary operation. Follow-up of 2 to 8 months after discharge showed that the wounds of all patients healed well. One patient who underwent femoral artery ligation had calf amputation due to foot ischemic necrosis, and the rest of the patients regained normal walking ability. The pulsatile mass disappeared in inguinal region of all patients. B-ultrasound or CTA re-examination in 6 patients showed that the blood flow of femoral artery had good patency, and there was no pseudoaneurysm recurrence. Conclusions: Early debridement, tumor resection, and individualized artery treatment should be performed in patients with femoral artery pseudoaneurysm combined with infected wounds. Besides, proper drainage and personalized repair strategy should be conducted according to the wound condition to achieve a good outcome.

Abstract
Objective: To explore the effects of porcine urinary bladder matrix (UBM) on the motility and polarization of bone marrow-derived macrophages in mice, so as to provide evidence for the rational selection of stent in clinical wound repair. Methods: The method of experimental research was used. The microstructure of porcine UBM and absorbable dressing was observed under scanning electron microscope. Polyacrylamide gel electrophoresis was used to observe the protein distribution of the two stent extracts. The primary macrophages were induced from bone marrow-derived cells isolated from six 6-8-week-old male C57BL/6J mice (mouse age, sex, and strain, the same below) and identified. Three batches of macrophages were divided into porcine UBM extract group and absorbable dressing extract group. The cells in each group were cultured with Dulbecco's modified Eagle medium/F12 medium containing the corresponding extracts. The cell migration rate was detected and calculated on 1, 3, and 7 d after scratching by scratch test. The number of migrated cells at 12 and 24 h of culture was detected by Transwell experiment. The percentages of CD206 and CD86 positive cells at 24 h of culture was detected by flow cytometer. The numbers of sample in the above cell experiments were all 3. An incision was prepared on the left and right back of twelve mice, respectively. The left incision of each mouse was included in porcine UBM group and the right incision was included in absorbable dressing group, and the corresponding stents were implanted into the incisions respectively. On post operation day (POD) 7 and 14, the number of inflammatory cells infiltrated in the stent was detected by hematoxylin-eosin staining; the number of F4/80, transforming growth factor-β1 (TGF-β1), vascular endothelial growth factor (VEGF), and matrix metalloprotein-9 (MMP-9) positive cells and type Ⅰ collagen deposition in stents were observed by immunohistochemistry; the percentages of F4/80, CD86, and CD206 positive cells were observed by immunofluorescence staining. The numbers of sample in the above animal experiments were all 6. Data were statistically analyzed with analysis of variance for factorial design, analysis of variance for repeated measurement, and independent sample t test. Results: Porcine UBM has a dense basement membrane structure on one side and porous propria containing a fibrous structures on the other. Both sides of the absorbable dressing had three-dimensional porous structure. In the molecular weight range of (50-70)×103, multiple non-type Ⅰ collagen bands appeared in the lanes of porcine UBM extract, while no obvious bands appeared in the lanes of absorbable dressing extract. It had been identified that mouse bone marrow-derived cells had been successfully induced into macrophages. The cell migration rates in porcine UBM extract group were significantly higher than those in absorbable dressing extract group on 1, 3, and 7 d after scratching (with t values of 15.31, 19.76, and 20.58, respectively, P<0.05). The numbers of migrated cells in porcine UBM extract group were significantly more than those in absorbable dressing extract group at 12 and 24 h of culture (with t values of 12.20 and 33.26, respectively, P<0.05). At 24 h of culture, the percentage of CD86 positive cells in porcine UBM extract group ((1.27±0.19)%) was significantly lower than (7.34±0.14)% in absorbable dressing extract group (t=17.03, P<0.05);the percentage of CD206 positive cells in porcine UBM extract group was (73.4±0.7)%, significantly higher than (32.2±0.5)% in absorbable dressing extract group (t=119.10, P<0.05). On POD 7 and 14, the numbers of inflammatory cells infiltrated in the stents in porcine UBM group was significantly more than those in absorbable dressing group (with t values of 6.58 and 10.70, respectively, P<0.05). On POD 7 and 14, the numbers of F4/80, TGF-β1, VEGF, and MMP-9 positive cells in the stents in porcine UBM group were significantly more than those in absorbable dressing group (with t values of 46.11, 40.69, 13.90, 14.15, 19.79, 32.93, 12.16, and 13.21, respectively, P<0.05); type Ⅰ collagen deposition in the stents in porcine UBM group was more pronounced than that in absorbable dressing group; the percentages of CD206 positive cells in the stents in porcine UBM group were significantly higher than those in absorbable dressing group (with t values of 5.05 and 4.13, respectively, P<0.05), while the percentages of CD86 positive cells were significantly lower than those in absorbable dressing group (with t values of 20.90 and 19.64, respectively, P<0.05), and more M2-type macrophages were seen in the stents in porcine UBM group and more M1-type macrophages were seen in the stents in absorbable dressing group. Conclusions: Porcine UBM can enhance macrophage motility, induce M2 polarization and paracrine function, create a microenvironment containing growth factors such as TGF-β1 and MMP-9 tissue remodeling molecules, and promote tissue regeneration and extracellular matrix remodeling in mice.

Abstract
Objective: To explore the clinical effects of fractional carbon dioxide laser combined with autologous fat injection in the treatment of hypertrophic scar after burn. Methods: From April 2018 to April 2019, 12 patients with hypertrophic scar after burn who met the inclusion criteria were admitted to the Department of Plastic Surgery and Burns of Xuzhou Renci Hospital, and were included in this prospective randomized controlled clinical study. There were 7 males and 5 females with age of (32±11) years and scar area of (612±195) cm(2). One scar was selected from each patient and divided into two equal area scars, and they were divided into combined treatment group and laser alone group with 12 scars in each group according to the random number table. The scar in laser alone group was only treated with fractional carbon dioxide laser, while the scar in combined treatment group was injected with autologous granular fat and then treated with fractional carbon dioxide laser. Scars in the two groups were treated once every 2 months, totally 3 times. Before the first treatment and 6 months after the last treatment, the scars in the two groups were evaluated by modified Vancouver Scar Scale (mVSS), hematoxylin-eosin staining and color Doppler ultrasound. Six months after the last treatment, the curative effect of scars in the two groups was evaluated, and the effective number of scar treatment was calculated. The adverse reactions during the whole treatment were recorded. Data were statistically analyzed with independent sample t test, paired sample t test, and McNemar exact probability method test. Results: Six months after the last treatment, the mVSS score of scars in combined treatment group was (4.5±0.4) points, which was significantly lower than (7.8±0.6) points in laser alone group (t=10.000, P<0.01). Six months after the last treatment, the mVSS scores of scars in combined treatment group and laser alone group were significantly lower than those before the first treatment ((13.5±0.7) and (13.8±0.6) points, t=8.805, 9.010, P<0.01). The effective number of scar treatment in combined treatment group was significantly more than that in laser alone group (P<0.05). There was no scar aggravation, infection, or other adverse reactions during the treatment of scars in both groups. Before the first treatment, the scars in both groups had large collagen, disordered arrangement, proliferation of capillaries, infiltration of some inflammatory cells, and disappearance of skin appendages. Six months after the last treatment, the scar collagen in both groups was sparse and orderly arranged, and the vascular density was reduced. The improvement of scars in combined treatment group was more obvious than that of laser alone group. Six months after the last treatment, the scar thickness in combined treatment group was significantly smaller than that in laser alone group (t=2.657, P<0.05). Before the first treatment, the blood flow of scars in both groups was abundant; 6 months after the last treatment, the blood flow of scars in combined treatment group was significantly less than that in laser alone group. Conclusions: Fractional carbon dioxide laser combined with autologous fat injection in the treatment of hypertrophic scar after burn can significantly reduce the pain and itching symptoms of scar, and improve the thickness, texture, and congestion of scar. The combined treatment has synergistic effect and less adverse reactions, providing a more effective treatment for patients with hypertrophic scar.

Abstract
Objective: To analyze the mechanism of acidified silk protein sponge matrices and methanolized silk protein sponge matrices in promoting wound healing. Methods: The experimental method was conducted. Acidified silk protein sponge matrices with vascularization ability and methanolized silk protein sponge matrices without vascularization ability were prepared by improved freeze-drying method. General observation was performed. Internal morphology was observed with scanning electron microscope. The secondary structure was observed with X-ray diffractometer (XRD) and infrared spectrometer. Compressive modulus was tested by tensile machine. Two 3-week-old male Sprague-Dawley (SD) rats were used to isolate bone marrow mesenchymal stem cells (BMSCs) cultured in above-mentioned two silk protein sponge matrices, the number of cells was counted under laser scanning confocal microscope after 1, 6 days of culture. Four full-thickness skin defect wounds were made on each one of twelve 8-week-old male SD rats, which were divided into methanolized silk group (24 wounds) and acidified silk group (24 wounds) covered with the corresponding silk protein sponge matrices. On post operation day (POD) 3, 7, 10, and 14, general observation was performed and the remaining wound area was recorded. On POD 3, 7, and 14, the wounds and marginal tissue were collected for hematoxylin-eosin staining (HE) staining and Masson staining to observe growth of new tissue and collagen deposition and CD34 immunohistochemical staining to observe vascularization. Sample number of each index of each group at every time point in animal experiment was 6. Data were statistically analyzed with analysis of variance of factorial design, analysis of variance for repeated measurement, independent-samples t test, and Bonferroni correction. Results: Methanolized silk protein sponge matrices and acidified silk protein sponge matrices had the same composition and similar porous structure, with pore size of 300-500 μm. XRD showed that methanolized silk protein sponge matrices showed a significant crystallization peak, while acidified silk protein sponge matrices was mainly composed of amorphous structure. Infrared spectrometer showed that acidified silk protein sponge matrices appeared a strong absorption peak at 1 650 cm(-1), and the methanolized silk protein sponge matrices appeared a strong absorption peak at 1 630 cm(-1). Compressive modulus of methanolized silk protein sponge matrices was (23.8±1.3) kPa, which was significantly higher than (6.1±0.9) kPa of acidified silk protein sponge matrices (t=19.550, P<0.01). After one day of culture, BMSCs successfully adhered to the two kinds of silk protein sponge matrices, and the cells were not spread. After six days of culture, BMSCs were spread on the two kinds of silk protein sponge matrices, and the number of cells on the acidified silk protein sponge matrices increased significantly. On POD 3, the wounds of the 2 groups did not shrink significantly. On POD 7, the wound area in acidified silk group was significantly smaller than that in methanolized silk group, and new epithelium growth occurred at the wound edge. On POD 14, the wounds of acidified silk group basically healed, and the wounds of methanolized silk group were dry and shrinked significantly. Remaining wound area of acidified silk group on POD 3, 7, 10, and 14 were significantly smaller compared with that in methanolized silk group ( t=7.782, 10.620, 3.707, 6.830, P<0.05 or P<0.01). HE staining, Masson staining, and CD34 immunohistochemical staining showed on POD 3, new tissue growing into silk protein sponge matrices of wounds of acidified silk group was more than that in methanolized silk group, the former group secreted a small amount of collagen, collagen formation was not observed in the latter group, the number of vascular endothelial cells migrated into the matrices were more in the former group than the latter group; on POD 7, the area of new tissue covering matrices hole of wounds of acidified silk group was larger than that in methanolized silk group, collagen in the former group was more than that in the latter group and was evenly distributed, the number of blood vessels in the former group was more than that on POD 3, and the new blood vessels in the latter group were scattered; on POD 14, the new tissue in acidified silk group was similar in structure to normal skin tissue and formed a certain thickness, the new tissue in methanolized silk group basically grew into the matrices, the former group had rich collagen deposition, the latter group had scattered collagen, and blood vessels in the former group distributed uniformly and density of blood vessels was significantly higher than that in the latter group ((55.7±6.0) and (34.1±1.0) pieces/mm(2), respectively, t=9.042, P<0.01). Conclusions: Angiogenesis-promoting acidified silk protein sponge matrices have good cytocompatibility, which can facilitate the rapid formation of vascular network in wound area, providing sufficient blood supply to accelerate the tissue regeneration and collagen deposition, thereby promoting wound healing and improving healing quality, these effects are better than methanolized silk protein sponge matrices.

Abstract
Objective: To explore the efficacy of hierarchical medical mode path management on the continuous treatment for chronic wound patients. Methods: From June 2017 to September 2018, the clinical data of 101 patients with chronic wounds who were just discharged from Department of Wound Repair of the Affiliated Hospital of Jiangnan University (hereafter referred to as the author's affiliation) and still needed continuous treatment, meeting the inclusion criteria, were analyzed with the method of retrospective cohort study. Based on the management method of continuous treatment after discharge, the patients were divided into path management group (52 patients, 27 males and 25 females, aged (44±6) years, 57 wounds) and conventional management group (49 patients, 26 males and 23 females, aged (45±6) years, 53 wounds). The patients in path management group were carried out with full-path management under hierarchical medical mode, and the patients in conventional management group were carried out with conventional continuous treatment management. The discharge time from the author's affiliation was the time before continuous treatment management (hereafter referred to as before management), and 12 weeks post discharge was the time after continuous treatment management (hereafter referred to as after management). The depression and anxiety of patients in two groups were assessed by Hamilton Depression Scale 24 item version (HAMD-24) and Self-rating Anxiety Scale (SAS), and the positive ratios of depression and anxiety were calculated. The effective rates of wound treatment, times of debridement and dressing change, and treatment cost during the continuous treatment management period were counted. Data were statistically analyzed with two independent sample t test, chi-square test, Fisher's exact probability test, and Wilcoxon rank-sum test. Results: (1) Before management, the HAMD-24 and SAS scores of patients in two groups were similar. After management, the HAMD-24 and SAS scores of patients in path management group were significantly lower than those of conventional management group (t=4.341, 3.840, P<0.01). Before and after management, the positive rates of depression and anxiety of patients in two groups were similar. (2) After management, the effective rate of wound treatment of patients in path management group was 98.25% (56/57), which was significantly higher than 86.79% (46/53) of conventional management group (χ(2)=5.341, P<0.05). (3) During the management, the times of debridement and dressing change in patients of path management group was 20±4, which was significantly less than 27±7 of conventional management group (t=5.833, P<0.01). (4) During the management, the treatment cost of patients in path management group was (2 479±213) yuan, which was significantly less than (5 215±326) yuan of conventional management group (t=50.185, P<0.01). Conclusions: In the continuous treatment of chronic wound patients, the full-path management under hierarchical medical mode can improve the effective rate of wound treatment, reduce the times of debridement and dressing change and treatment cost, and improve their psychological state.

Objective: To preliminarily observe the clinical effects of vacuum sealing drainage (VSD) in the treatment of alkali burn wounds. Methods: From June 2016 to March 2020, 60 male patients with alkali burns who met the inclusion criteria and hospitalized in the Affiliated Hospital of Jiangnan University were recruited in this prospectively randomized control study. According to the random number table, silver sulfadiazine group and VSD group were both allocated with 30 patients, aged (36±8) and (35±10) years respectively; with total burn area of (7.2±2.0) % and (8.5±3.0) % total body surface area respectively. After admission, patients in silver sulfadiazine group were treated with conventional silver sulfadiazine dressing change once a day after debridement; patients in VSD group were given continuous VSD treatment after debridement, with the negative pressure setting at -10.67 kPa, and the negative pressure materials were replaced every 6 to 8 days. On treatment day 1, 4, and 7, the exudate from the wounds of patients in silver sulfadiazine group and the wound drainage fluid of patients in VSD group were collected, the pH value was measured by a portable pH meter, and the volume of exudate/drainage fluid was measured. After 7, 14, and 21 days of treatment, the wound healing rates of patients were calculated in the two groups. Before treatment and 7 days after treatment, venous blood was collected from the patients in the two groups to detect the serum level of tumor necrosis factor α (TNF-α) and interleukin 8 (IL-8). Within treatment day 14, Visual Analogue Scale was used to assess the pain score of patients in the two groups during each time of dressing change. The medical costs and discharge satisfaction scores of patients in the two groups were recorded. Data were statistically analyzed with analysis of variance for repeated measurement, t test, and Bonferroni correction. Results: (1) On treatment day 1, 4, and 7, the pH values of the drainage fluid of patients in VSD group were 9.75±0.59, 9.01±0.46, and 8.13±0.28, respectively, which were significantly higher than 9.35±0.62, 8.18±0.18, and 7.58±0.09 of exudate of patients in silver sulfadiazine group (t=2.03, 6.80, 7.56, P<0.05 or P<0.01). On treatment day 1 and 4, the volumes of drainage fluid of patients in VSD group were (553±83) and (239±65) mL respectively, which were significantly higher than (440±77) and (175±49) mL of exudate of patients in silver sulfadiazine group (t=3.44, 2.24, P<0.05). On treatment day 7, the volume of drainage fluid of patients in VSD group was (21±8) mL, which was significantly lower than (149±44) mL of exudate of patients in silver sulfadiazine group (t=-12.61, P<0.01). (2) After 7, 14, and 21 days of treatment, the wound healing rates of patients in VSD group were (39±6) %, (74±10) %, and (92±3) %, respectively, which were significantly higher than (25±3) %, (59±6) %, and (77±6) % in silver sulfadiazine group (t=7.07, 5.59, 7.09, P<0.01). (3) Before treatment, the serum levels of TNF-α and IL-8 of patients in the two groups were similar. After 7 days of treatment, the serum levels of TNF-α and IL-8 of patients in VSD group were significantly lower than those in silver sulfadiazine group (t=-8.75, -8.04, P<0.01). (4) The pain score during dressing change and medical cost of patients in VSD group were significantly lower than those in silver sulfadiazine group (t=-4.28, -7.56, P<0.01), while the discharge satisfaction score of patients in VSD group was significantly higher than that in silver sulfadiazine group (t=10.91, P<0.05). Conclusions: The application of VSD technology in clinical alkali burn wounds can effectively promote the removal of residual lye, alleviate the further damage of lye to skin tissue, shorten the wound healing time, effectively remove inflammatory mediators, reduce the pain of dressing change, decrease the total cost of treatment, and enhance satisfaction of patient.

Abstract
Maggot therapy is a kind of biological therapy that uses maggot to eat and remove the necrotic tissue of wounds, while it has no adverse effect on living tissue with blood supply. Besides, maggot therapy can promote wound healing through various mechanisms, which has been used for debridement and treatment of wounds as early as hundreds of years ago. With the discovery and application of antibiotics, maggot therapy faded out of the medical field once. However, with the abuse of antibiotics and increasing drug resistance of bacteria in recent years, maggot therapy attracts widespread attention of clinicians again. This article reviews the advances in the application of maggot therapy in chronic wounds.

Abstract
In August 2nd Kunshan factory aluminum dust explosion accident 2014, 35 severe mass burn patients were admitted to our hospital, including 18 men and 17 women, aged 21 to 50 (38±9) years. Their severe injuries caused much difficulty to the treatment. In the early period of treatment, a series of measures of nursing human resource management were implemented, such as carrying out training program for non-burn speciality nurses of different levels and origin, grouping and task-dividing, organizing work schedule and assigning in a unified way, and establishing monitoring team of speciality quality. Except for 2 cases of deaths in the early period, the other 33 patients were treated and nursed timely and effectively in the early period. The rescue rate arrived at 94.3% (33/35) on the 17th day post burn. In this period, no such nursing adverse event and complication occurred as bed-dropping, unplanned extubation, coagulation in veins of lower limb, catheter-related infection, or cross infection.

Abstract
Objective: To explore the changes of helper T lymphocytes 17 (Th17) and regulatory T lymphocytes (Tregs) in peripheral blood of patients with extensive burn at early stage in August 2nd aluminum dust explosion accident in Kunshan factory (hereinafter referred to as Kunshan explosion accident) and the significance. Methods: Twenty patients with extensive burn in Kunshan explosion accident admitted to our department of burns and plastic surgery were enrolled in burn group, and 10 healthy adult volunteers with no history of smoking were enrolled in healthy control group. Five mL of peripheral venous blood samples were collected from patients in burn group at admission (≤post injury hour 6, PIH 6) and PIH 24, and on post injury day (PID) 7, and from volunteers in healthy control group respectively. The percentages of CD64(+) T lymphocytes, human leukocyte antigen-DR positive (HLA-DR(+) ) T lymphocytes, CD3(+) CD8(-) Th17, and CD4(+) CD25(+) Tregs in peripheral blood T lymphocytes were determined by flow cytometer. Results: (1) The percentages of CD64(+) T lymphocytes in peripheral blood T lymphocytes of patients in burn group at admission and PIH 24 [(2.35±0.32)% and (4.02±0.15)%] were higher than (0.67±0.11)% of healthy volunteers in healthy control group. The percentage of CD64(+) T lymphocytes in peripheral blood T lymphocytes of patients in burn group on PID 7 [(0.39±0.25)% ] was lower than that of healthy volunteers in healthy control group. The percentages of HLA-DR(+) T lymphocytes in peripheral blood T lymphocytes of patients in burn group at admission and PIH 24 [(54±18)% and (72±17)%] were higher than (38±14)% of healthy volunteers in healthy control group. The percentage of HLA-DR(+) T lymphocytes in peripheral blood T lymphocytes of patients in burn group on PID 7 [(28±15)% ] was lower than that of healthy volunteers in healthy control group. (2) The percentages of CD3(+) CD8(-)Th17 in peripheral blood T lymphocytes of patients in burn group at admission and PIH 24 [(4.21±0.46)% and (7.38±0.39)%] were higher than (0.98±0.09)% of healthy volunteers in healthy control group. The percentage of CD3(+) CD8(-)Th17 in peripheral blood T lymphocytes of patients in burn group on PID 7 [(0.81±0.05)% ] was lower than that of healthy volunteers in healthy control group. (3) The percentages of CD4(+) CD25(+) Tregs in peripheral blood T lymphocytes of patients in burn group at admission and PIH 24, and on PID 7 [(1.78±0.26)%, (1.26±0.37)%, and (0.38±0.03)%] were lower than (3.24±0.52)% of healthy volunteers in healthy control group. Conclusions: The percentage of Th17 in peripheral blood T lymphocytes of patients with extensive burn at early stage in Kunshan explosion accident increased at first and then decreased compared with that of healthy volunteers, indicating that the patients' immune function increased first and then weakened. The percentages of Tregs in peripheral blood T lymphocytes at each time point were lower than the percentage of healthy volunteers, indicating that the patients' immunomodulation gradually weakened after extensive burns.

Abstract
Objective: To explore experience of wound treatment of extremely severe mass burn patients involved in August 2nd Kunshan factory aluminum dust explosion accident. Methods: On August 2nd, 2014, 98 extremely severe burn mass patients involved in August 2nd Kunshan factory aluminum dust explosion accident were admitted to 20 hospitals in China. The patients with complete medical record were enrolled in the study and divided into microskin graft group with 56 patients and Meek skin graft group with 42 patients. Split-thickness skin in area of residual skin were resected to repair wounds of patients in microskin graft group and Meek skin graft group by microskin grafting and Meek miniature skin grafting, respectively. The residual wound size on 28 days post injury and wound infection after skin grafting of patients in the two groups, and position of donor site of all patients were retrospectively analyzed. Data were processed with t test and chi-square test. Results: The size of residual wound of patients in Meek skin graft group on 28 days post injury was (59±13)% total body surface area (TBSA), which was obviously smaller than that in microskin graft group [(70±14)%TBSA, t=4.379, P<0.05]. Twenty-nine patients in microskin graft group and 11 patients in Meek skin graft group suffered from obvious wound infection after skin grafting. Wounds of patients in two groups were repaired with residual skin around wound in head, trunk, groin, armpit, and uncommon donor sites of scrotum (4 patients), vola (10 patients), and toe or finger web (8 patients). Conclusions: Meek skin graft is the first choice for wound repair of extremely severe burn mass patients, with faster wound healing, less wound infection. Uncommon donor sites of scrotum, vola, and toe or finger web can also be used for wound repair in case of lack of skin.

Abstract
Objective: To investigate the effects of application of citrate anticoagulation in bedside continuous blood purification (CBP) of severe burn patients with sepsis, so as to provide reference for choosing anticoagulants in CBP of these patients. Methods: Thirty severe burn patients with sepsis, conforming to the study criteria, were admitted to our burn intensive care unit from January 2014 to July 2017. Patients were divided into heparin group and citrate group according to computer randomization method, with 15 cases in each group. Patients in two groups all received bedside CBP treatment. Patients in heparin group used local heparin anticoagulation, while patients in citrate group used local citrate anticoagulation. Time of predicted single-time CBP treatment, time of single-time CBP treatment, time of accumulative CBP treatment, and rate of reaching the standard of CBP treatment time were counted. Changes of prothrombin time (PT), activated partial thromboplastin time (APTT), international normalized ratio (INR), fibrinogen, serum procalcitonin, and C-reactive protein (CRP) of patients before and after treatment were monitored. Hemorrhage in wounds, incision on trachea, and arteriovenous intubation point, and other complications during and after CBP treatment were observed. Data were processed with independent sample t test and chi-square test. Results: (1) Time of predicted single-time CBP treatment of patients in the two groups was equal. Time of single-time CBP treatment and time of accumulative CBP treatment of patients in citrate group were longer than those in heparin group. Rate of reaching the standard of CBP treatment time of patients in citrate group was significantly higher than that in heparin group (χ(2)=16.655, P<0.01). (2) There was no statistically significant difference in PT, APTT, INR, fibrinogen, serum procalcitonin, and CRP of patients in the two groups before CBP treatment (t=0.203, -1.006, 0.203, 0.039, -1.591, -0.824, P>0.05). PT and APTT of patients in citrate group after CBP treatment were (14.2±1.6) and (45±7) s, respectively, significantly shorter than (15.5±1.4) and (53±6) s in heparin group (t=2.395, 3.321, P<0.05 or P<0.01). INR of patients in citrate group after CBP treatment was 1.13±0.12, significantly lower than 1.24±0.12 in heparin group (t=2.395, P<0.05). Fibrinogen of patients in citrate group after CBP treatment was (3.5±0.6) g/L, significantly higher than (3.0±0.6) g/L in heparin group (t=-2.427, P<0.05). Serum procalcitonin and CRP of patients in citrate group after CBP treatment were significantly lower than those in heparin group (t=2.520, 2.710, P<0.05). Decreased degree of serum procalcitonin and CRP of patients in citrate group after CBP treatment were (1.8±0.6) ng/mL and (143±69) mg/L, respectively, significantly higher than (0.9±0.6) ng/mL and (95±50) mg/L in heparin group (t=-4.033, -2.170, P<0.05 or P<0.01). (3) During CBP treatment, patients in heparin group experienced 21 times of exacerbation of wound hemorrhage and 10 times of new hemorrhage, including 2 times of hemorrhage at incision on trachea and 8 times of hemorrhage at arteriovenous intubation point. No exacerbation of hemorrhage or new hemorrhage happened in patients of citrate group. After CBP treatment, no electrolyte disturbance happened in patients of heparin group, but 1 patient in citrate group experienced hypocalcemia. Conclusions: Application of citrate anticoagulation in bedside CBP of severe burn patients with sepsis shows light impact on systematic coagulation status, and can effectively decrease inflammation reaction of burn sepsis with low rate of hemorrhage.

Abstract
The mental disorders, scar, and dysfunction will affect the work and study of patients with extensive burn, which can further affect the quality of life and the rate of return to society. Under the premise of saving life, the function of patients with extensive burn should be reserved as much as possible for a better living quality. In addition to the specialized treatment, body positioning, therapeutic exercise, orthosis application, and psychotherapy can be used in the early stage of burn rehabilitation. Early rehabilitation training is beneficial to the circulatory system, immune system, functional and psychological recovery of patients. It can also improve the quality of extensive burn treatment, and decrease deformities and the incidence of complications in the late stage.
