ABSTRACT
Objective:To investigate the therapeutic effect of skull drilling and/or grinding combined with artificial dermis and vacuum sealing drainage in repairing scalp defects with skull exposure.Methods:From October 2014 to May 2018, 18 patients with scalp defect and skull exposure were treated in the Department of Burn and Plastic Surgery, the Second Clinical College of North Sichuan Medical College, including 10 males and 8 females, with an average age of 64 years (range, 34-86 years). The patients were divided into two groups: group A (by drilling skull or/and grinding combined with artificial dermis cover and vacuum sealing drainage plus two split thickness skin graft repair) and group B (by drilling skull or/andgrinding combined with artificial dermis cover plus two covering leather grinding stage split thickness skin graft repair), 9 cases in each group. The head wound granulation tissue, postoperative complications, skin graft survival rate and wound healing time were compared between the two groups. Vancouver scar assessment scale (VSS) was used to evaluate the wound healing in the two groups.Results:The time of granulation cultivation in group A and group B was (16.44±1.42) days and (29.11±13.32) days, the difference was statistically significant ( P<0.05); The wound healing time of group A and group B was (26.00±3.32) days and (40.67±14.37) days, the difference was statistically significant ( P<0.05); The postoperative complications of group A and group B were 1 case and 5 cases respectively, the difference was statistically significant ( P<0.05). The skin graft survival rates of group A and group B were (97.11±3.44)% and (95.00±4.74)%, the difference was not statistically significant ( P>0.05); The wound scar VSS scores of group A and group B were (7.67±1.32) points and (8.78±1.99) points, the difference was not statistically significant ( P>0.05). Conclusions:By drilling skull and/or grinding combined with artificial dermis cover and vacuum sealing drainage and two stage split thickness skin graft for repairing scalp defect with skull exposure wound can not only better scalp defect with skull exposure wounds, and reduce the postoperative complications, and significantly accelerate wound healing, but also can effectively improve the quality of wound healing, which is worthy of clinical application.
ABSTRACT
Objective: To preliminary explore the effect of decellularized adipose tissue (DAT) combined with vacuum sealing drainage (VSD) on wound inflammation in pigs. Methods: The DAT was prepared through the process of freeze-thaw, enzymatic digestion, organic solvent extraction, and vacuum freeze-drying. The appearance of DAT was observed before and after freeze-drying. HE staining was used to observe its structure and acellular effect. Eighteen male Bama minipigs were recruited, and four dorsal skin soft tissue wounds in diameter of 4 cm were made on each pig and randomly divided into 4 groups for different treatments. The wounds were treated with DAT combined with VSD in DAT/VSD group, DAT in DAT group, VSD in VSD group, and sterile gauze dressing in control group. HE staining was performed at 3, 7, 10, and 14 days after treatment. Moreover, the expressions of inflammatory factors [interleukin 1β (IL-1β), IL-6, and tumor necrosis factor α (TNF-α)], as well as the phenotypes of M1 and M2 macrophage phenotypic markers [inducible nitric oxide synthase (iNOS) and arginase 1 (ARG-1)] were detected by real-time fluorescence quantitative PCR (qRT-PCR). ELISA was used to determine the content of iNOS and ARG-1. Results: General observation and HE staining showed that DAT obtained in this study had a loose porous structure without cells. The neutrophils of wounds were significantly less in DAT/VSD group than in control group and DAT group ( P0.05) between DAT/VSD group and VSD group. And the neutrophils were significantly less in DAT/VSD group than in other three groups ( P<0.05) at 7, 10, and 14 days. The mRNA expressions of IL-1β, IL-6, TNF-α, and iNOS were significantly lower in DAT/VSD group than in other three groups at 3, 7, 10, and 14 days ( P<0.05), while the mRNA expression of ARG-1 was significantly higher in DAT/VSD group than in other three groups ( P<0.05). ELISA showed that the content of iNOS was significantly lower in DAT/VSD group than in other three groups at 3, 7, 10, and 14 days ( P<0.05), while the content of ARG-1 was significantly higher in DAT/VSD group than in other three groups ( P<0.05). Conclusion: DAT combined with VSD can significantly reduce inflammatory cell infiltration during wound healing, regulate the expressions of inflammatory factors and macrophage phenotype, and the effect is better than single use of each and conventional dressing change.
ABSTRACT
BACKGROUND: Vacuum sealing drainage can enhance acute and chronic wound healing. The ratio of collagen type I/III play a critical role in the structural stability of skin tissue and skin repair, but its change during vacuum sealing drainage accelerating wound healing remains unclear. OBJECTIVE: To observe the effect of vacuum sealing drainage on the ratio of collagen type I/III during wound healing and to explore the potential mechanism underlying acute wound repair in rats. METHODS: A full-thickness wound, with a diameter of 20 mm, was created on the back of healthy male rats. All model rats were then randomized into two groups: blank control and vacuum sealing drainage groups. The wound surface was photographed at three observational time points (1, 3, 7 days after operation), and wound closure rate was calculated and compared. The mRNA and protein expression levels of type I collagen and type III collagen and ratio of collagen type I/III were detected by RT-qPCR and immunohistochemistry. The structure of granulation tissue and length of re-epithelialization were histologically detected. RESULTS AND CONCLUSION: Compared with the blank control group, treatment with vacuum sealing drainage significantly increased the expression of type I collagen and type III collagen at mRNA and protein levels (P < 0.05), enhanced wound healing rate (P < 0.05) as well as increasing the ratio of collagen type I/III starting from the 3rd day after operation (P < 0.05). To conclude, the vacuum sealing drainage can accelerate wound healing by up-regulating the protein expression of type I collagen and type III collagen, the ratio of collagen type I/III and increasing wound tensile strength.

Vacuum sealing drainage (VSD) is frequently used in abdominal surgeries. However, relevant guidelines are rare. Chinese Trauma Surgeon Association organized a committee composed of 28 experts across China in July 2017, aiming to provide an evidence-based recommendation for the application of VSD in abdominal surgeries. Eleven questions regarding the use of VSD in abdominal surgeries were addressed: (1) which type of materials should be respectively chosen for the intraperitoneal cavity, retroperitoneal cavity and superficial incisions? (2) Can VSD be preventively used for a high-risk abdominal incision with primary suture? (3) Can VSD be used in severely contaminated/infected abdominal surgical sites? (4) Can VSD be used for temporary abdominal cavity closure under some special conditions such as severe abdominal trauma, infection, liver transplantation and intra-abdominal volume increment in abdominal compartment syndrome? (5) Can VSD be used in abdominal organ inflammation, injury, or postoperative drainage? (6) Can VSD be used in the treatment of intestinal fistula and pancreatic fistula? (7) Can VSD be used in the treatment of intra-abdominal and extra-peritoneal abscess? (8) Can VSD be used in the treatment of abdominal wall wounds, wound cavity, and defects? (9) Does VSD increase the risk of bleeding? (10) Does VSD increase the risk of intestinal wall injury? (11) Does VSD increase the risk of peritoneal adhesion? Focusing on these questions, evidence-based recommendations were given accordingly. VSD was strongly recommended regarding the questions 2-4. Weak recommendations were made regarding questions 1 and 5-11. Proper use of VSD in abdominal surgeries can lower the risk of infection in abdominal incisions with primary suture, treat severely contaminated/infected surgical sites and facilitate temporary abdominal cavity closure.

ABSTRACT
Objective: To evaluate the clinical value of skin stretching device in repair of diabetic foot wound. Methods: A retrospective analysis was made on the clinical data of 48 cases with diabetic foot wound who were treated with skin stretching device (trial group, n=24) and with the vacuum sealing drainage combined with skin graft (control group, n=24) respectively between October 2015 and July 2016. There was no significant difference in gender, age, side, course of disease, TEXAS stage between 2 groups ( P>0.05). Both patients in 2 groups were treated with sensitive antibiotics according to the results of bacterial culture. Results: One case in control group was infected and the skin graft failed, and 1 case in trial group was infected after the treatment, and the two wounds healed after symptomatic treatment. The wounds of the other patients healed successfully, and the healing time of the trial group was significantly shorter than that of the control group [(12.8±11.6) days vs. (22.3±10.4) days; t=2.987, P=0.005). All patients were followed up 3-12 months after operation, and no wound dehiscence or recurrence occurred during follow-up. Conclusion: Compared with the vacuum sealing drainage combined with skin graft, the application of skin stretching device in the repair of diabetic foot wound has advantages, such as easy to operate, shorten the wound healing time, and the appearance of wound was similar with the adjacent skin.

ABSTRACT
Objective To investigate the effect of ultrasound debridement combined with vacuum sealing drainage on the treatment of diabetic foot ulcer and the potential mechanism. Methods Eighty-one patients with diabetic ulcer were randomly divided into two groups:ultrasound debridement combined with vacuum sealing drain-age as the experimental group,routine debridement combined with vacuum sealing drainage as the control group. The clinical curative effect,the reduction rate of the wound,the rate of blastocyst and the rate of bacterial clear-ance and blood flow were detected.Results The clinical curative effect in the experimental group was significantly better than that in the control group(P < 0.05). The rates of wound reduction and granulation were significantly higher than those in the control group(P<0.05).After 14-day treatment,the blood perfusion in the experimental group was significantly higher than that in the control group(P<0.05),and the expression of HIF-1α and VEGF in the ulcer tissue was significantly higher than that in the control group(P<0.05).Conclusions Ultrasound de-bridement combined with vacuum sealing drainage can improve the clinical efficacy,wound reduction rate,granu-lation coverage rate and bacterial clearance rate,and increase ulcer tissue blood flow. The potential mechanism is related with the increases of HIF-1α and VEGF in ulcer tissue.
ABSTRACT
Objective To measure the oxygen partial pressure (PtO2) within a situation of vacuum sealing drainage (VSD) implement, and to discuss the potential mechanism of VSD alleviating skeletal muscle ischemia reperfusion (I/R) injury in rabbits. Methods Rabbits were randomly(random number) divided into three groups: sham (n=10), I/R (n=10) and I/R+VSD (n=10) groups. In the I/R group, left hind limb ischemia was induced by clamping the femoral artery and vein for 4 h, then released for 6 h, to allow reperfusion of the limb. VSD was only performed in the I/R+VSD group during the reperfusion period. All rabbits were administered a series test of PtO2 in different time points before and after reperfusion, and the left hind limb skeletal muscle and ear vein blood samples were immediately harvested for biochemical analyses, including hypoxia inducible factor 1 alpha (HIF-1α) mRNA and protein, and lactic acid (LA). One-way analysis of variance (ANOVA), Fisher's least significant difference (LSD) test or Tamhane's T2 test was used where appropriate to analyze the experimental results. Results The levels of PtO2 in the I/R and I/R+VSD groups were decreased after ischemia, but no significant difference was noted between the two groups (t=1.322, P=0.296). The PtO2 levels in the I/R+VSD group were less increased than those in the I/R group after reperfusion (t=2.015, P=0.046). The levels of HIF-1α mRNA and protein were increased after I/R injuries (F=10.120, P=0.002; F=36.480, P<0.01; F=6.960, P=0.015, F=4.470, P=0.035), and the levels in the I/R+VSD group were greater than those in the I/R group (t=1.799, P=0.048, t=5.911, P=0.019; t=1.878, P=0.046, t=2.609, P=0.030). The LA levels were significantly increased in the skeletal muscle and blood samples in the I/R and I/R+NPWT groups compared with those in the sham group at the final stage (F=9.540, P=0.002 and F=13.750, P<0.01), but the levels in the I/R+VSD group were less than those in the I/R group (t=2.263, P=0.040 and t=3.617, P=0.027). Conclusions Our results suggested that VSD technique decreased PtO2 in regional ischemic muscles and led to increases in HIF-1α mRNA and protein that subsequent accumulation of less LA in both of regional skeletal muscle and systemic blood circulation, which provided protection effect after I/R injury in rabbits.
