Ultracompact temporal integrator using graphene-based long-range a mix of both plasmonic waveguides.
Data were statistically analyzed with analysis of variance for repeated measurement and Bonferroni correction, t test, Fisher's exact probability test, and Mann-Whitney U test. Results (1) After matching, during the first to third 24 h post injury, the total fluid replacement coefficient and glucose input volume of patients in inhalation injury group were significantly higher than those in non-inhalation injury group (F=4.202, 10.671, P0.05). Conclusions The presence of inhalation injury can lead to increased fluid requirement in massive burn patients during shock stage. An appropriate increase of fluid volume in the fluid resuscitation of burn patients combined with inhalation injury would be beneficial for maintaining ideal urine output.Objective To explore the clinical effect of pre-expanded deltopectoral flap in the repair of faciocervical lesion and defect. Methods From July 2004 to August 2018, 355 patients with faciocervical lesion and defect were admitted to the First Affiliated Hospital of Air Force Medical University, including 200 males and 155 females aged 4 to 48 years with major conditions including thermal burn scars, and type Ⅲ and Ⅳ facial-cervical deformities. During the stage Ⅰ skin soft tissue expander implantation surgery, according to the size and location of lesion and defect, expanders with appropriate volume were placed to expand the deltopectoral area. During the stage Ⅱ flap pedicled transposition surgery, after the expander was expanded to the desired volume, the impairment tissue was removed, the flap was designed according to the size of the defect (the unilateral defect area was 7 cm×5 cm to 17 cm×16 cm) and pedicled transposition was carried out. The incision in the chest donor area was directly sutured and clos to 120 months, the elasticity, texture, and color of the flaps of patients were similar to the surrounding tissue of the recipient area, and the face and neck were symmetrical, not bloated. Conclusions The deltopectoral flap obtained by overexpansion has a larger area and a thinner thickness, and the elasticity, texture, and color are similar to the surrounding tissue of the recipient area. After transfer, a stable appearance of the face and neck can be obtained. The main complications are infection and expander exposure, most of which occurred after stage Ⅰ skin soft tissue expander implantation surgery.Objective To explore the effect of combined application of pulsed dye laser (PDL) and ultra-pulsed fractional carbon dioxide laser (UFCL) in the treatment of pediatric large burn scars at early stage. Methods One hundred and twenty pediatric patients with large burn scars at early stage conforming to the study criteria were admitted to the People's Hospital of Hunan Province from January 2016 to December 2019. Their data were retrospectively analyzed by the method of single case-control study. There were 78 males and 42 females with age of (4.2±0.8) years and scar area of (100.3±0.7) cm(2). PDL combined with UFCL was used for the first time. Selleck CHIR-124 The treatment interval of PDL was a month and the treatment interval of UFCL was 3 months. The total treatment cycle was 6 months, with 2 PDL treatments alone and two combined treatments. Before the first combined treatment and 6 months after two combined treatments, the curative effect was assessed using Patient and Observer Scar Assessment Scale (POSAS) by doctors and fcan alleviate symptoms and improve the quality of pediatric patients' life, and is worthy to be popularized and applied in clinic.Objective To investigate the expressions and effects of autophagy-related genes in bleomycin-induced skin fibrosis of mice. Methods (1) Totally 72 male BALB/c mice aged 6 weeks were divided into blank control group, simple phosphate buffer solution (PBS) group, and bleomycin group according to the random number table, with 24 mice in each group. Mice in blank control group received no treatment, and 100 μL of PBS and bleomycin (1 mg/mL) were respectively injected subcutaneously in the back skin of mice in simple PBS and bleomycin group, once a day for 28 days. On injection day (ID) 7, 14, 21, and 28, 6 mice in each group were collected to observe the skin change on the back of mice with naked eyes. After the observation, the mice were sacrificed and skin tissue on the back was taken. Skin tissue of mice on ID 28 was collected to measure the thickness of skin tissue by routine hematoxylin-eosin staining and observe skin tissue morphology by Masson staining. Skin tissue on ID 7, 14, 21, and 28 was taken to dete (t=0.82, 0.45, 0.50, 0.79, 0.51, 0.50, P less then 0.01). On ID 28, the protein expressions of p62, LC3 Ⅱ, and Beclin-1 in the skin tissue of mice in bleomycin group were significantly lower than those in blank control group and simple PBS group (t=0.77, 0.54, 0.52, 0.50, 0.51, 0.50, P less then 0.05). (7) After culture for 72 h, the expression of LC3 Ⅱ in Fbs of bleomycin group was significantly lower than that of blank control group and simple PBS group, respectively. Conclusions In the process of bleomycin stimulating skin fibrosis, autophagy-related genes increase firstly and then decrease. When the autophagy process is activated, it is expected to reverse the process of skin fibrosis.Objective To investigate the clinical effect of Zhang's super tension-relieving suture applied in high-tension wound closure. Methods From January to August 2019, 19 eligible patients with scar or black hairy nevus were treated with Zhang's super tension-relieving suture for outpatient operation in the Department of Plastic and Reconstructive Surgery of Shanghai Ninth People's Hospital Affiliated to Shanghai Jiao Tong University School of Medicine. The patients were composed of 6 males and 13 females, aged 10-68 years, with 8 keloids, 3 hypertrophic scars, 5 atrophic scars, and 3 black hairy nevus. The operation sites included lower jaw in 2 cases, neck in 3 cases, chest in 4 cases, abdomen in 2 cases, and limbs in 8 cases. The size of scars and black hairy nevus before surgery ranged from 1.4 cm×1.1 cm to 10.0 cm×4.0 cm. All the lesions underwent excision alone with both sides of the incision undermined for 1 to 2 cm, and the wound size ranged from 2.6 cm×2.6 cm to 12.6 cm×6.8 cm. Zhang's super tension-relieving suture was applied with barbed suture, and the wound edges were naturally jointed with relaxation and low tension by pushing normal skin on both sides to the middle.
