To investigate the feasibility of using limited flap to repair different wounds by using fractionated transfer of one flap to repair different wounds in 8 cases. Among them, 2 cases were pedicle iliolumbar skin flaps, 2 cases were pedicle iliolumbar and hypogastric combined skin flaps, 2 cases were free latissimus dorsal myocutaneous flaps, 1 case was gastrocnemius myocutaneous flaps, and 1 case was deltopectoral skin flap. The flap in donor area was isolated normally, and then transferred to repair the main wound or the wound following scar excision. The other remnant wounds were treated by using thorough debridement. Blood supply training was performed from two weeks after operation. When the flap had reliable blood supply, a second-stage operation was performed. The remnant wounds were repaired by anterograde or reversed transfer. According to the ways of the second-stage operation, blood supply training and dissection of the pedicles were performed at 2 weeks after operation in some of the patients. All these flaps survived, and the wounds were repaired with satisfactory. The appearances and functions were improved after a six months follow-up. Results suggested that it was safe and feasible to use the same pedicle repaired different parts, which can solve the problem of using limited flap to repair different wounds.

BACKGROUND: Thoracodorsal artery perforator flap can relieve damage to donor site and avoid bulk in the recipient site,but dissociation of perforating branch took time.Some one believed that it should be done by very experienced physicians and some muscle tissues should be reserved.OBJECTIVE: To investigate the method,effectiveness and clinical application of improved latissimus dorsi flap based on perforator flap conception for reconstruction of soft tissue defects of lower extremity.METHODS: A total of 17 patients needing skin flap transplantation were selected.12 latissimus dorsi musculocutaneous/muscle flaps,3 latissimus dorsi flaps with a few muscle and 2 double-leaf segmental latissimus dorsi compound flaps were designed based on perforator flap conception.According to the territory of latissimus dorsi musculocutaneous flap,a skin paddle in which anterior underlying muscle and main perforator was designed,extend about to the anterior edge of the latissimus dorsi muscle.An additional latissimus dorsi muscle flap was selected for soft tissue enlargement if necessary.Sometimes,double-leaf segmental latissimus dorsi musculocutaneous/muscle flap,including one muscle-sparing latissimus dorsi musculocutaneous flap and the other segmental latissimus dorsi muscle flap nourished by the lateral branches of the thoracodorsal vessels was selected to repair two adjacent defects.The harvested tissue area ranged from 12 cm×8 cm to 28 cm×17 cm.Survival state of skin flap,together with shape and function of donor site and recipient site of skin flap were observed.RESULTS AND CONCLUSION: Following skin flap transplantation,one case developed vascular crisis that was relieved following re-exploration for vessel anastomosis.All skin flap survived.Second-stage skin grafting was done on one muscle flap wound.All donor sites were sutured directly.After a follow-up of 3 to 18 months in 15 cases,only two cases received two-stage plastic operation because bulky flaps brought some trouble in wearing shoes.Improved latissimus dorsi flap based on perforator flap conception can reduce damage to the donor site and the receipt area bulk.Double-leaf segmental latissimus dorsi compound flaps can repair both heel and toe wound.The versatile latissimus dorsi flap designed using thoracodorsal artery perforator flap conception is an ideal flap for repairing widespread soft tissue defects in the lower extremity.

Objective To evaluate efficacy and safety of intravenous chemotherapy combined with TACE in the treatment of gastric cancer with hepatic metastasis.Methods In this study 60 gastric cancer patients with hepatic metastasis were divided into two groups randomly,the trial group (30 cases) took intravenous chemotherapy consisted of docetaxel 60 mg/m2 intravenous drip d1,oxaliplatin 80 mg/m2 intravenous drip d1 followed by 5-fiuorouracil 500 mg/m2 intravenous drip d1-5 after TACE.The control group (30 cases) took the same chemotherapy protocol and one treatment cycle covering 4 weeks.Results The overall response rate in trial group was 53％ and the increase rate of Karnofsky was 70％ while that was 37％ and 40％ respectively in the control group (P ＜ 0.05).The median overall survival of trial group was 13 months and which was 8 months in the control group (P ＜ 0.05),meanwhile the toxicities and side reactions of trial group didn't increase notably.Conclusions Intravenous chemotherapy combined with TACE is safe and more effective in the treatment of gastric cancer with hepatic metastasis.

This article briefly describes the establishment and development of Department of Burns and Reconstructive Surgery of Xiangya Hospital of Central South University. Over the past 60 years, our department has achieved great achievements in the treatment of burns by the combination of traditional Chinese medicine with western medicine, treatment of severe burns, and burn wounds repaired by flaps, and established Hunan burn rescue medical collaboration network. With the development of society and the change of disease spectrum, the future development direction of our department mainly focuses on treatment of severe burns, scar prevention, and treatment of acute and chronic wounds.

Because of the complex injury mechanism, hidden tissue injury, and severe systemic injury, the clinical diagnosis and treatment of electric burn still face many challenges, and the mortality and disability rate are still high. In view of the particularity of electric burn and the prognosis of electric burn, especially the quality of wound repair, the author puts forward some personal views on fluid resuscitation, organ protection, and wound repair on the basis of summarizing the new methods of diagnosis and treatment of electric burn at home and abroad at present, and preliminarily explores the standardized diagnosis and treatment of electric burn.

Chronic wounds are characterized by complex pathogenesis, long course of disease, and occur mostly in middle-aged and elderly people. As the population ages, chronic wounds have gradually become significant burden on the affected patients and the healthcare system. In the past decade, cold atmosphere plasma (CAP) was found to have the effects of resisting infection and promoting wound healing. By reviewing recent researches on the treatment of chronic wounds and biological effects of CAP at home and abroad, this article summarizes the research progress of CAP in the treatment of chronic wounds, aiming at providing a reference for the treatment of chronic wounds.

Many reasons can cause damage to a certain part of body, with the damaged tissue showing some corresponding characteristics. There are many uncertainties in the repair of damaged body parts, making it difficult to achieve the ideal function and appearance. In recent years, the repair of mangled injury has made significant progress, but it still faces many challenges. Based on the clinical practice and the current progress in the assessment and repair of mangled injury, this paper summarizes the causes, clinical features, injury assessment, treatment options, repair measures, and the risks of limb salvage, and then puts forward some personal opinions on the definition of mangled injury and treatment strategy optimization for reference.

Repair and reconstruction surgery is not just a simple repair and reconstruction of tissue and organ defects in different parts, but also requires perfect repair that matches the defect and confuses the real. The thinning strategy of perforator flap is one of its main contents. In recent years, the concept of pure skin perforator flap and its clinical application have overturned the traditional concept that flaps must carry subdermal vascular plexus and improved our understanding of flap surgery, and it is expected to enhance the level of repair and reconstruction. This article explores the harvest of thinned perforator flaps, especially the harvest of innovative pure skin perforator flap with the thickness similar to full thickness skin, as well as the preoperative detection of perforator vessels, blood supply evaluation of perforator flaps, and their clinical applications. It proposes a "Jinshan" repair that perfectly matches the recipient area defect, and also prospects research on the perforasome and three-dimensional visualized digital anatomy of pure skin perforator flaps.

OBJECTIVETo evaluate the repairing methods of bulky tissue defect of forearm with flaps.

METHODSTwenty-one burned patients with wounds in the forearm were enrolled in this study. The injury causes were high-voltage electricity, hot press or crush injury. After local debridement, the forearm defects were repaired with pedicled complex flaps, latissimus dorsi musculocutaneous island flaps or large thoraco-abdominal flaps immediately.

RESULTSAll the flaps survived very well with satisfactory results except for 1 patient in whom local ischemic necrosis and sub-flap infection at the distal end of the flap occurred.

CONCLUSIONEarly debridement followed by skin flaps with pedicles or musculocutaneous flaps transfer could be simple, safe and reliable treatment strategies in the management of bulky tissue defects of the forearm due to burn, electric injury, or other devastating injuries.

Objective: To analyze clinical characteristics and wound repair methods and effects of patients with upper limb electric burns. Methods: Medical records of 136 patients with upper limb electric burn who met the inclusion criteria and hospitalized in our unit from January 2015 to March 2019 were retrospectively analyzed. Proportion in patients with electric burns in the same period, gender, age, admission time, categories, injury causes, injury voltage, burn area and depth of upper limb, simultaneous injury of both upper limbs, and early wound treatment measure of patients with upper limb electric burn were recorded. The main repair methods of each affected limb were classified and recorded. The overall efficacy of the patients was recorded, including postoperative wound complications and healing condition. The patients repaired with distal pedicled flaps and those with free flaps were followed up for 3 to 6 months. The survival rate of flaps were recorded, the function of affected limbs after operation was evaluated, and the satisfaction degree of patients was investigated by Curative Effect Score Table. The amputation rate, age, and burn area of upper limbs of patients caused by high-voltage and low-voltage electricity were compared. Data were processed with Wilcoxon rank sum test, chi-square test, or Fisher′s exact probability test. Results: (1) The number of upper limb electric burn patients accounted for 88.3% of 154 patients with electric burns hospitalized in the same period, including 117 males and 19 females, aged 1 year and 2 months to 72 years [(34±18) years], admitted 1 h to 48 d after injury, including 51 electricians, 32 rural migrant workers, 31 students and preschool children, and 22 patients belonging to other categories. Patients of the first two categories were mainly injured by work accidents, and those of the latter two categories mainly suffered from touching power source or power leakage. Among all the patients, 75 cases were injured by high-voltage electric burn, and 61 cases were injured by low-voltage electric burn, with burn area of upper limb from 0.2% to 16.0% [2% (1%, 5%)] total body surface area (TBSA) and area of wounds deep to bone from 0.2% to 15.0% [2% (1%, 5%)] TBSA. Two upper limbs in 54 cases were simultaneously injured, accounting for 39.7%. Early fasciotomy was performed for 73 limbs. (2) Thirteen affected limbs were treated with dressing change, 2 affected limbs were sutured directly after debridement, 56 affected limbs were repaired by skin grafting, 12 affected limbs were repaired by local flap, 45 affected limbs were repaired by distal pedicled flap, 22 affected limbs were repaired by free flap, and 40 affected limbs were amputated (accounting for 21.1%). (3) One case died of pulmonary infection, sepsis, and multiple organ failure after operation, and the rest patients were all cured. One case with avulsion of abdominal flap was repaired by skin grafting after dressing change. The anterolateral thigh flap in one case necrotized after transplantation, which was replaced by pedicled abdominal flap. Seven cases had small erosion on the pedicle or margin after transplantation of abdominal flap and were healed by dressing change. Six cases had local bruising at the distal end after transplantation of abdominal flap and were healed after conservative treatment such as hyperbaric oxygen. The other flaps survived well. (4) The survival rate of distal pedicled flap grafting was 97.8% (44/45), which was close to that of free flap grafting (95.5%, 21/22, P>0.05). The function recovery of affected limb after free flap grafting was better than that of distal pedicled flap grafting (Z=-3.054, P<0.01), but their satisfaction degree of patients was similar (Z=-0.474, P>0.05). (5) Patients with high-voltage electric burn had higher amputation rate, older age, and larger upper limb burn area than those with low-voltage electric burn (χ²=4.743, Z=-2.801, -6.469, P<0.05 or P<0.01). Conclusions Upper extremity electric burn often occurs in children, electricians, and rural migrant workers with high rate of amputation. Teachers and parents should strengthen safety education for children and manage power source of life well. Workers should improve safety awareness and operate standardly. Fasciotomy for relaxation should be performed for electric burn wound as soon as possible, and flap grafting can effectively repair wound after early debridement. The function recovery of affected upper limb repaired with free flap grafting is better.
