Abstract
Objective: To explore the effect of exercise prescription based on a progressive mode in treating elderly patients with lower limb dysfunction after deep burns. Methods: A randomized controlled trial was conducted. From January 2021 to January 2023, 60 elderly patients with lower limb dysfunction after deep burns who met the inclusion criteria were admitted to the First Affiliated Hospital of Air Force Medical University. The patients were divided into conventional rehabilitation group (30 cases, 17 males and 13 females, aged (65±3) years) and combined rehabilitation group (30 cases, 16 males and 14 females, aged (64±3) years) according to the random number table. For patients in both groups, the red-light treatment was started after the lower limb wounds healed or when the total area of scattered residual wounds was less than 1% of the total body surface area. After 2 weeks of red-light treatment, the patients in conventional rehabilitation group were given conventional rehabilitation treatments, including joint stretching, resistance, and balance training; in addition to conventional rehabilitation treatments, the patients in combined rehabilitation group were given exercise prescription training based on a progressive mode three times a week, mainly including dumbbell press, Bobath ball horizontal support, and high-level pulldown trainings. The training time for patients in both groups was 12 weeks. Before training (after 2 weeks of red-light treatment) and after 12 weeks of training, the upper limb and lower limb motor functions of the patients were evaluated using the simple Fugl-Meyer scale, the physical fitness of patients was evaluated using the simple physical fitness scale, and the patient's risk of falling was evaluated by the time consumed for the timed up and go test. The adverse events of patients that occurred during training were recorded. After 12 weeks of training, a self-designed satisfaction survey was conducted to investigate patients' satisfaction with the training effect. Data were statistically analyzed with independent sample t test, paired sample t test, Mann-Whitney U test, Wilcoxon signed rank test, and chi-square test. Results: Before training, the scores of upper limb and lower limb motor functions of patients between the two groups were similar (P>0.05). After 12 weeks of training, the scores of upper limb motor function of patients in conventional rehabilitation group and combined rehabilitation group were significantly higher than those before training (with t values of -11.42 and -13.67, respectively, P<0.05), but there was no statistically significant difference between the two groups (P>0.05). The score of lower limb motor function of patients in combined rehabilitation group was 28.9±2.6, which was significantly higher than 26.3±2.6 in conventional rehabilitation group (t=-3.90, P<0.05), and the scores of lower limb motor function of patients in conventional rehabilitation group and combined rehabilitation group were significantly higher than those before training (with t values of -4.14 and -6.94, respectively, P<0.05). Before training, the individual and total scores of physical fitness of patients between the two groups were similar (P>0.05). After 12 weeks of training, the balance ability score, walking speed score, chair sitting score, and total score of physical fitness of patients in conventional rehabilitation group and combined rehabilitation group were significantly increased compared with those before training (with Z values of -4.38, -3.55, -3.88, -4.65, -4.58, -4.68, -4.42, and -4.48, respectively, P<0.05), and the balance ability score, walking speed score, chair sitting score, and total score of physical fitness of patients in combined rehabilitation group were significantly increased compared with those in conventional rehabilitation group (with Z values of -3.93, -3.41, -3.19, and -5.33, P<0.05). Before training, the time consumed for the timed up and go test for patient's risk of falling in the two groups was close (P>0.05). After 12 weeks of training, the time consumed for the timed up and go test for patient's risk of falling in combined rehabilitation group was (28.0±2.1) s, which was significantly shorter than (30.5±1.8) s in conventional rehabilitation group (t=4.94, P<0.05). Moreover, the time consumed for the timed up and go test for patient's risk of falling in both conventional rehabilitation group and combined rehabilitation group was significantly shorter than that before training (with t values of 14.80 and 15.86, respectively, P<0.05). During the training period, no adverse events such as muscle tissue strain, edema, or falling occurred in any patient. After 12 weeks of training, the satisfaction score of patients with the training effect in combined rehabilitation group was 13.5±1.2, which was significantly higher than 8.5±1.4 in conventional rehabilitation group (t=21.78, P<0.05). Conclusions: The exercise prescription training based on a progressive mode can significantly promote the recovery of lower limb motor function and physical fitness of elderly patients with lower limb dysfunction after deep burns, and effectively reduce the patient's risk of falling without causing adverse events during the training period, resulting in patient's high satisfaction with the training effect.

Abstract
Objective: To investigate the effects of anterolateral thigh chimeric perforator flap in repairing complex wounds of foot and ankle. Methods: A retrospective observational study was conducted. From May 2018 to June 2022, 23 patients who met the inclusion criteria were admitted to the First Affiliated Hospital of Air Force Medical University to repair complex wounds of foot and ankle with anterolateral thigh chimeric perforator flaps, including 15 males and 8 females, aged from 20 to 66 years. The wounds were all accompanied by bone exposure and defects, and were complicated with varying degrees of infection. All patients underwent debridement and continuous vacuum sealing drainage treatment for 1 week in stage Ⅰ, with the skin and soft tissue defect area after debridement being 10 cm×5 cm to 22 cm×7 cm. In stage Ⅱ, the anterolateral thigh chimeric perforator flap was used to cover the defective wound, of which the muscle flap was used to fill the deep invalid cavity of the ankle joint or cover bone and internal fixation exposures, and the skin flap was used to cover the superficial wound, with the area of the skin flap ranging from 11 cm×6 cm to 23 cm×8 cm, and the area of the muscle flap ranging from 4.0 cm×2.5 cm to 8.0 cm×5.0 cm. The survival of the flap was observed after operation. During follow-up, the color, texture, appearance, and complications of the flap were observed, the function of ankle joint and its range of dorsiflexion motion and plantar flexion motion were measured, and the scar hyperplasia and muscular hernia in donor area were observed. Results: Ecchymosis and epidermal necrosis occurred at the tip of the flap in 1 patient on 5 days after operation and healed after dressing change for 1 week; the other flaps of patients survived successfully. After 6 to 40 months of follow-up, the color, texture, and shape of flaps were good, but 1 patient was not satisfied with the shape of the flap because of flap swelling; the ankle joint movement was basically normal, the dorsiflexion motion was 15-30°, and the plantar flexion motion was 20-45°; the scar hyperplasia in the donor area of the flap was not obvious, and no muscular hernia occurred. Conclusions: The anterolateral thigh chimeric perforator flap can effectively fill the deep invalid cavity of ankle joint and cover the superficial wound at the same time, with minimal damage to the donor site. So it is an ideal flap for repairing the complex wounds of foot and ankle.

Abstract
Objective: To explore the curative effects of medial plantar free flap in reconstructing electric burn wound and scar contracture in the palm. Methods: A retrospective observational study was conducted. From January 2020 to January 2023, 6 patients with electric burn wounds or scar contracture in the palm who met the inclusion criteria were admitted to the First Affiliated Hospital of Air Force Medical University, including 5 males and 1 female, aged 35 to 55 years. The wound area was 5.0 cm×3.0 cm-8.0 cm×7.0 cm after the debridement of electric burn wounds or resection of scar in the palm. The medial plantar free flap anastomosed with cutaneous nerve was used for wound reconstruction, with flap area of 5.5 cm×3.5 cm-8.5 cm×7.5 cm. The wound in the donor site was repaired with transplantation of abdominal full-thickness skin graft. After surgery, the survival of flaps and skin grafts were observed, the shape and texture of flap and the recovery of donor site of flap were observed, and the holding function of the affected hand was assessed. At the last follow-up, the two-point discrimination distance of flap was measured, the sensory recovery of flap was evaluated with the trial standard for the evaluation of the functions of the upper limbs of the Hand Surgery Society of the Chinese Medical Association, and the function recovery of flap was evaluated by post-surgery flap function evaluation scale. Results: After surgery, 5 flaps survived well, while the distal part of 1 flap was partially necrotic, which was repaired by medium-thickness skin graft from lateral thigh after debridement. All the skin grafts at the donor sites survived well. During follow-up of 3 to 24 months, the flap was not bloated, the texture and color were good, the match with the surrounding tissue was high, with no obvious scar contracture occurred at the donor site. The affected hand had good holding function. At the last follow-up, the two-point discrimination distance of flap was 6-8 mm, the flap sensation recovery was as follows: 5 flaps recovered to grade S3+, 1 flap recovered to grade S3, and the functional evaluation of flaps was excellent in 5 cases and good in 1 case. The patients basically returned to normal life and work. Conclusions: The medial plantar free flap with cutaneous nerve anastomosis has many advantages, such as high matching degree of appearance, good sensory recovery, and holding function of the affected hand. It is an ideal choice for the reconstruction of the electric burn wound and scar contracture in the palm.

Abstract
OBJECTIVE To evaluate the effectiveness and safety of Rotarex catheter system in treating femoropopliteal artery stenosis accompanied with thrombosis. METHODS From Jun. 2017 to Dec. 2019, the clinical data of 32 femoropopliteal artery stenosis accompanied with thrombosis cases treated with Rotarex catheter system were retrospectively analyzed. There were 23 males and 9 females aged from 50 to 89 years and the mean age was (70.7±10.3) years. Six cases had acute course of disease (≤2 weeks), 17 cases had subacute course of disease (>2 weeks, ≤3 months), and 9 cases had chronic course of disease (>3 months). Mean lesion length was (23.4±13.7) cm, mean occlusion length was (19.9±13.3) cm, and in-stent occlusion 7 cases. The superficial femoral artery (SFA) was involved in 13 cases, the popliteal artery (PA) was involved in 8 cases, and both SFA and PA were involved in the other 11 cases. All the cases were treated with Rotarex catheter system. When necessary, suction with large lumen catheter was enabled. Residual stenosis was treated with percutaneous transluminal angioplasty (PTA). Drug-coated balloon (DCB) was only used in patients with financial status, and stent was used only when it was necessary. Heparin was used for 24 h after procedures, and after that, antiplatelet agents were used. Doppler ultrasonography was taken during the followed-up. RESULTS Technical success was 100%, and mean procedure time was (107.4±21.5) min. 8F (1F≈0.33 mm) and 6F Rotarex catheter were used in 27 and 5 cases respectively. In 27 cases, forward flow was obtained immediately after debulking with Rotarex catheter, and in the other 5 cases, suction with large lumen catheters were used. PTA was used in all 32 cases. DCB were used in 8 cases, of which 4 were used in in-stent stenosis. Twelve cases were implanted stents. There were no perioperative deaths. The only one procedure related complication was distal embolism. We took out the thrombus with guiding catheter. In all cases, mean hospital stay were (4.6±1.5) d. The ankle brachial index increased from 0.32±0.15 to 0.86±0.10 after treatment (t=-16.847, P < 0.001). The Rutherford stages decreased significantly (Z=-4.518, P < 0.001). All the patients were followed up for 6.0-36.0 months, and the median time was 16.0 months. 2 cases stopped antiplatelet agents, which resulted in acute thrombosis. Another percutaneous mechanical thrombectomy and PTA were taken in one of them. Two cases died of cardiovascular disease during the follow-up, and no amputation was observed. Target lesion restenosis occurred in 7 cases during the follow-up, and target lesion revascularization (TLR) was taken in two of them. CONCLUSION In treating femoropopliteal artery stenosis accompanied with thrombosis, Rotarex catheter can remove thrombus effectively, and that can expose underlying lesions and reduce stent use and complications rates. It is a safe and effective method.

Abstract
Objective: To explore the family rehabilitation model for children with scar contracture after hand burns and observe its efficacy. Methods: A retrospective non-randomized controlled study was conducted. From March 2020 to March 2021, 30 children with scar contracture after deep partial-thickness to full-thickness burns of hands, who met the inclusion criteria, were hospitalized in the Burn Center of PLA of the First Affiliated Hospital of Air Force Medical University. According to the rehabilitation model adopted, 18 children (23 affected hands) were included in a group mainly treated by family rehabilitation (hereinafter referred to as family rehabilitation group), and 12 children (15 affected hands) were included in another group mainly treated by hospital rehabilitation (hereinafter referred to as hospital rehabilitation group). In the former group, there were 11 males and 7 females, aged (4.8±2.1) years, who began rehabilitation treatment (3.1±0.8) d after wound healing; in the latter group, there were 7 males and 5 females, aged (4.6±2.1) years, who began rehabilitation treatment (2.8±0.7) d after wound healing. The children in hospital rehabilitation group mainly received active and passive rehabilitation training in the hospital, supplemented by independent rehabilitation training after returning home; after 1-2 weeks of active and passive rehabilitation training in the hospital, the children in family rehabilitation group received active and passive rehabilitation training at home under the guidance of rehabilitation therapists through WeChat platform. Both groups of children were treated for 6 months. During the treatment, they wore pressure gloves and used hand flexion training belts and finger splitting braces. Before treatment and after 6 months of treatment, the modified Vancouver scar scale, the total active movement of the hand method, and Carroll quantitative test of upper extremity function were used to score/rate the scar of the affected hand (with the difference of scar score between before treatment and after treatment being calculated), the joint range of motion (with excellent and good ratio being calculated), and the function of the affected limb, respectively. Data were statistically analyzed with independent sample t test, equivalence test, Fisher's exact probability test, and Mann-Whitney U test. Results: The differences of scar scores of the affected hands of children in family rehabilitation group and hospital rehabilitation group between after 6 months of treatment and those before treatment were 3.0 (2.0, 7.0) and 3.0 (2.0, 8.0) respectively (with 95% confidence interval of 2.37-5.38 and 1.95-5.91). The 95% confidence interval of the difference between the differences of the two groups was -2.43-2.21, which was within the equivalent boundary value of -3-3 (P<0.05). The excellent and good ratios of joint range of motion of the affected hand of children in family rehabilitation group and hospital rehabilitation group were 3/23 and 2/15 respectively before treatment, and 15/23 and 12/15 respectively after 6 months of treatment. The ratings of joint range of motion of the affected hand of children in family rehabilitation group and hospital rehabilitation group after 6 months of treatment were significantly higher than those before treatment (with Z values of 3.58 and 2.30, respectively, P<0.05), but the ratings of joint range of motion of the affected hand between the two groups were similar before treatment and after 6 months of treatment (with Z values of 0.39 and 0.55, respectively, P>0.05). The functional ratings of the affected limbs of children in family rehabilitation group and hospital rehabilitation group after 6 months of treatment were significantly higher than those before treatment (with Z values of 3.98 and 3.51, respectively, P<0.05), but the functional ratings of the affected limbs between the two groups were similar before treatment and after 6 months of treatment (with Z values of 1.27 and 0.38, respectively, P>0.05). Conclusions: The WeChat platform assisted rehabilitation treatment with mainly family rehabilitation, combined with hand flexion and extension brace can effectively reduce the scarring after children's hand burns, improve the joint range of motion of the affected hands, and promote the recovery of affected limb function. The effect is similar to that of hospital-based rehabilitation providing an optional rehabilitation, treatment method for children who cannot continue to receive treatment in hospital.

Abstract
Objective: To observe the effect of progressive core muscle group training combined with lower limb intelligent rehabilitation training on burn patients with lower limb dysfunction. Methods: A prospective randomized controlled study was conducted. From March 2017 to May 2020, 60 patients with motor and balance dysfunction after deep partial-thickness burns or full-thickness burns of both lower extremities who met the inclusion criteria were admitted to the First Affiliated Hospital of Air Force Military Medical University. They were divided into simple intelligent rehabilitation group (30 cases, 20 males and 10 females, aged (40±3) years) and combined rehabilitation group (30 cases, 16 males and 14 females, aged (39±3) years) according to the random number table method. The patients in both groups started red light treatment after the wound healing or when the scattered residual wound area was less than 5% total body surface area. After 2 weeks of red light treatment, patients in the combined rehabilitation group started progressive core muscle group training on the basis of lower limb intelligent rehabilitation training in simple intelligent rehabilitation group, and the training time was 6 weeks. Before and after 6 weeks of training, the lower limb motor function was evaluated with the simple Fugl-Meyer scale, the balance capacity was evaluated with the Berg balance scale, and the walking capacity was evaluated with the Holden walking ability rating scale. After 6 weeks of training, a self-designed questionnaire was used to investigate patients' satisfaction for the treatment effect. The patients were followed up for 6 months after the treatment to observe the balance stability of standing on one foot in the flexion position and their participation in activities of daily life. Data were statistically analyzed with independent sample t test, paired sample t test, and chi-square test. Results: Before training, the lower limb motor function score of patients in simple intelligent rehabilitation group was 24.9±2.7, which was close to 23.9±2.3 in combined rehabilitation group (P>0.05). After 6 weeks of training, the lower limb motor function score of patients in combined rehabilitation group was 29.6±3.9, which was significantly higher than 27.3±3.8 in simple rehabilitation group (t=-2.28, P<0.05). The lower limb motor function scores of patients in combined rehabilitation group and simple intelligent rehabilitation group after 6 weeks of training were significantly higher than those before training (with t values of -6.50 and -3.21, respectively, P<0.01). After 6 weeks of training, the balance capacity score of patients in combined rehabilitation group was 41±7, which was significantly higher than 36±5 in simple intelligent rehabilitation group (t=-2.68, P<0.05); the balance capacity scores of patients in combined rehabilitation group and simple intelligent rehabilitation group after 6 weeks of training were significantly higher than those before training (with t values of -8.72 and -8.09, respectively, P<0.01). After 6 weeks of training, the walking capacity grading of patients in combined rehabilitation group was significantly improved compared with that in simple intelligent rehabilitation group (χ2=-2.14, P<0.05), and the walking capacity grading of patients in simple intelligent rehabilitation group and combined rehabilitation group after 6 weeks of training was significantly improved compared with that before treatment (with χ2 values of -4.94 and -5.26, respectively, P<0.01). After 6 weeks of training, the satisfaction score for the treatment effect of patients in combined rehabilitation group was 13.7±1.2, which was significantly higher than 7.8±1.4 in simple intelligent rehabilitation group (t=22.84, P<0.01). The patients in both groups could stand on one foot to maintain balance in the flexion position of lower limb, and their activities of daily life were not affected 6 months after treatment. Conclusions: On the basis of conventional rehabilitation therapy, the combination of progressive core muscle group training and lower limb intelligent rehabilitation training can significantly promote the recovery of lower limb motor and balance function of burn patients.

Abstract
Acid fibroblast growth factor (aFGF) is a member of fibroblast growth factors (FGF) family, widely promoting embryonic development, wound healing, vascular regeneration, nerve injury repair, as well as regulating immune metabolism. Many pathophysiological processes, such as inflammation, neovascularization, proliferation and migration of repair cells, and deposition of collagen and other extracellular matrix are involved in the process of wound healing. Based on the relevant literature in recent years, this article mainly reviews the research progresses on the roles and mechanism of aFGF in biological signal transduction, regulation of cell growth, and involvement in tissue repair, and discusses the current research hot spots as well as the prospective future direction of clinical applications of aFGF in the aspect of clinical pharmacokinetics and safety.

Abstract
Objective: To investigate the effects of compound analgesia on ultra-pulsed fractional carbon dioxide laser (UFCL) treatment of post-burn hypertrophic s in children. Methods: A prospective randomized controlled study was conducted. From April 2018 to March 2020, 169 pediatric patients with post-burn hypertrophic s admitted to the First Affiliated Hospital of Air Force Medical University were randomly divided into general anesthesia alone group (39 cases, 19 males and 20 females, aged 35 (21, 48) months), general anesthesia+lidocaine group (41 cases, 23 males and 18 females, aged 42 (22, 68) months), general anesthesia+ibuprofen suppository group (41 cases, 25 males and 16 females, aged 38 (26, 52) months), and three-drug combination group with general anesthesia + lidocaine+ibuprofen suppository (48 cases, 25 males and 23 females, aged 42 (25, 60) months), and the pediatric patients in each group were treated with corresponding analgesic regimens when UFCL was used to treat s, and the pediatric patients were given comprehensive care throughout the treatment process. The pain degree of pediatric patients scar was evaluated by facial expression,legs,activity,cry,and consolability (FLACC) of children's pain behavior scale at 0 (immediately), 1, 2, and 4 h after awakening from the first anesthesia, respectively. At 4 h after awakening from the first anesthesia of postoperative pain assessment, the self-made analgesia satisfaction questionnaire was used to evaluate the satisfaction for the analgesic effect of the pediatric patients or their families, and the satisfaction rate was calculated. Within 2 h after the first operation, the occurrences of adverse reactions of the pediatric patients, such as nausea and vomiting, headache, dizziness, drowsiness, etc, were observed and recorded. Before the first treatment and 1 month after the last treatment, the Vancouver scar scale (VSS) was used to evaluate the pediatric patients scar, and the difference value between the two was calculated. Data were statistically analyzed with least significant difference test, Kruskal-Wallis H test, chi-square test and Fisher's exact probability test. Results: At 0 h after awakening from the first anesthesia, the FLACC scores of pediatric patients in general anesthesia+lidocaine group, general anesthesia+ibuprofen suppository group and three-drug combination group were significantly lower than those in general anesthesia alone group (P<0.01). The FLACC scores of the pediatric patients in anesthesia+ibuprofen suppository group and three-drug combination group were significantly lower than that in general anesthesia+lidocaine group (P<0.01), and the FLACC score of the pediatric patients in three-drug combination group was significantly lower than that in general anesthesia+ibuprofen suppository group (P<0.01). At 1 and 2 h after awakening from the first anesthesia, the FLACC scores of pediatric patients in general anesthesia+ibuprofen suppository group and three-drug combination group were both significantly lower than those in general anesthesia alone group and general anesthesia+lidocaine group (P<0.01), and the FLACC score of the pediatric patients in three-drug combination group was significantly lower than that in general anesthesia+ibuprofen suppository group (P<0.01). At 4 h after awakening from the first anesthesia, the FLACC scores of the pediatric patients in general anesthesia+ibuprofen suppository group and three-drug combination group were significantly lower than those in general anesthesia alone group and general anesthesia+lidocaine group (P<0.01). At 4 h after awakening from the first anesthesia, the satisfactions rate with the analgesic effect in the four groups of pediatric patients or their families were 79.49% (31/39), 85.37% (35/41), 87.80% (36/41), and 97.92% (47/48), respectively. The satisfaction rate of the pediatric patients in three-drug combination group was significantly higher than those in general anesthesia alone group, general anesthesia+lidocaine group, general anesthesia+ibuprofen suppository group. Within 2 h after the first operation, there was no significant difference in the overall comparison of adverse reactions such as nausea and vomiting, headache, dizziness, and drowsiness of pediatric patients among the 4 groups (P>0.05). The VSS scores of pediatric patients before the first treatment, 1 month after the last treatment, and and the difference value between the two in the 4 groups were not significantly different (P>0.05). Conclusions: Three-drug combination for analgesia has a good effect in the treatment of hypertrophic scars after burn in pediatric patients with UFCL. Pediatric patients or their families are highly satisfied with the effect, and the treatment effect and incidence of adverse reactions are similar to other analgesic regimens, so it is recommended to be promoted in clinical practice.

Abstract
Objective: To evaluate the effect of mechanical debulking in treating arteriosclerosis occlusive disease of lower extremity. Methods: The clinical data of 52 arteriosclerosis occlusive disease of lower extremity cases treated with Rotarex mechanical debulking system from June 2017 to June 2020 at Department of Intervention Vascular Surgery,Peking University Third Hospital were retrospectively analyzed. There were 37 males and 15 females,aged(69.4±10.1)years(range:47 to 89 years).Lesion length was (21.6±12.9)cm(range:4 to 45 cm),occlusion length was (18.5±11.8)cm(range:4 to 45 cm).The lesion was located in iliac artery(IA) in 6 cases,femoral-popliteal artery(FPA) in 42 cases,and both IA and FPA in 4 cases. All the cases were treated with Rotarex mechanical debulking system. Residual stenosis more than 50% were treated with percutaneous transluminal angioplasty(PTA).Drug coated balloon was used in part of them,and stent was used only when it was necessary. The patient's operation, complications, postoperative target vessel restenosis and reoperation were collected. The paired sample t test and rank sum test was used for data comparison and the postoperative target vessel patency rate was analyzed by Kaplan-Meier survival curve. Results: All the 52 cases obtained technical success. Percutaneous transluminal angioplasty was used in all cases,and drug coated balloon were used in 11 cases. Twenty-six stents were implanted in 24 cases (2 cases implanted 2 stents).Nine stents were implanted in IA and 15 in FPA. The length of stents was (11.3±3.3)cm(range:6 to 23 cm).There were 3 procedure related complications: one of them was acute occlusion in an iliac lesion,and thrombectomy was applied urgently,and the result was good. And the other two were distal embolism. The thrombus were took out with guiding catheter. The hospital stay was (4.8±1.9)days. The ankle brachial index increased from 0.34±0.16 to 0.81±0.16 after treatment(t=-25.160,P<0.01).The Rutherford stages decreased from (M(IQR)) 3(1) to 1(1(Z=-6.825,P<0.01).The median followed up time was 19 months(range:6 to 42 months).Two cases stopped antiplatelet agents during follow-up and which result in acute thrombosis 2 weeks and 2 months later respectively. One of them was treated with percutaneous mechanical thrombectomy and the other one was not for gastrointestinal hemorrhage. Four cases died during follow-up,one case died of lung cancer,one died of abdominal infection,and the other 2 cases died of cardiovascular disease,and no amputation was observed. Target lesion restenosis(TLR) more than 50% occurred in 13 cases during the follow-up. All TLR were observed in FPA,and target lesion revascularization was taken in 3 of them. According to Kaplan-Meier survival curve analysis,half-year,1-year and 2-year cumulative patency rates of target vessels in this group was 94.2%,87.4% and 51.4%, respectively. And half-year and 1-year cumulative patency rates just in FPA cases was 92.9% and 84.3%, respectively. Conclusions: Percutaneous mechanical debulking using Rotarex catheter combining PTA can reduce the use of stents in femoral-popliteal artery. It is safe and effective in treating with arteriosclerosis obliterans of lower extremity.

Abstract
Objective: To investigate the effects of exosomes from human adipose-derived mesenchymal stem cells (ADSCs) on pulmonary vascular endothelial cells (PMVECs) injury in septic mice and its mechanism. Methods: The experimental research method was adopted. The primary ADSCs were isolated and cultured from the discarded fresh adipose tissue of 3 patients (female, 10-25 years old), who were admitted to the First Affiliated Hospital of Air Force Medical University undergoing abdominal surgery, and the cell morphology was observed by inverted phase contrast microscope on the 5th day. The expressions of CD29, CD34, CD44, CD45, CD73, and CD90 of ADSCs in the third passage were detected by flow cytometry. The third to the fifth passage of ADSCs were collected, and their exosomes from the cell supernatant were obtained by differential ultracentrifugation, and the shape, particle size, and the protein expressions of CD9, CD63, tumor susceptibility gene 101 (TSG101), and β-actin of exosomes were detected, respectively, by transmission electron microscopy, nano-particle tracking analysis and Western blotting. Twenty-four adult male BALB/c mice were adopted and were divided into normal control group, caecal ligation perforation (CLP) alone group, and CLP+ADSC-exosome group with each group of 8 according to random number table (the same grouping method below) and were treated accordingly. At 24 h after operation, tumor necrosis factor (TNF-α) and interleukin 1β (IL-1β) levels of mice serum were detected by enzyme-linked immunosorbent assay, and lung tissue morphology of mice was detected by hematoxylin-eosin and myeloperoxidase staining, and the expression of 8-hydroxy-deoxyguanosine (8-OHdG) of mouse lung cells was detected by immunofluorescence method. Primary PMVECs were obtained from 1-month-old C57 mice regardless gender by tissue block method. The expression of CD31 of PMVECs was detected by immunofluorescence and flow cytometry. The third passage of PMVECs was co-cultured with ADSCs derived exosomes for 12 h, and the phagocytosis of exosomes by PMVECs was detected by PKH26 kit. The third passage of PMVECs were adopted and were divided into blank control group, macrophage supernatant alone group, and macrophage supernatant+ADSC-exosome group, with 3 wells in each group, which were treated accordingly. After 24 h, the content of reactive oxygen species in cells was detected by flow cytometry, the expression of 8-OHdG in cells was detected by immunofluorescence, and Transwell assay was used to determine the permeability of cell monolayer. The number of samples in above were all 3. Data were statistically analyzed with one-way analysis of variance and least significant difference t test. Results: The primary ADSCs were isolated and cultured to day 5, growing densely in a spindle shape with a typical swirl-like. The percentages of CD29, CD44, CD73 and CD90 positive cells of ADSCs in the third passage were all >90%, and the percentages of CD34 and CD45 positive cells were <5%. Exosomes derived from ADSCs of the third to fifth passages showed a typical double-cavity disc-like structure with an average particle size of 103 nm, and the protein expressions of CD9, CD63 and TSG101 of exosomes were positive, while the protein expression of β-actin of exosomes was negative. At 24 h after operation, compared with those in normal control group, both the levels of TNF-α and IL-1β of mice serum in CLP alone group were significantly increased (with t values of 28.76 and 29.69, respectively, P<0.01); compared with those in CLP alone group, both the content of TNF-α and IL-1β of mice serum in CLP+ADSC-exosome group was significantly decreased (with t values of 9.90 and 4.76, respectively, P<0.05 or P<0.01). At 24 h after surgery, the pulmonary tissue structure of mice in normal control group was clear and complete without inflammatory cell infiltration; compared with those in normal control group, the pulmonary tissue edema and inflammatory cell infiltration of mice in CLP alone group were more obvious; compared with those in CLP alone group, the pulmonary tissue edema and inflammatory cell infiltration of mice in CLP+ADSC-exosome group were significantly reduced. At 24 h after operation, endothelial cells in lung tissues of mice in 3 groups showed positive expression of CD31; compared with that in normal control group, the fluorescence intensity of 8-OHdG positive cells of the lung tissues of mice in CLP alone group was significantly increased, and compared with that in CLP alone group, the fluorescence intensity of 8-OHdG positive cells in the lung tissues of mice in CLP+ADSC-exosome group was significantly decreased. The PMVECs in the 3rd passage showed CD31 positive expression by immunofluorescence, and the result of flow cytometry showed that CD31 positive cells accounted for 99.5%. At 12 h after co-culture, ADSC-derived exosomes were successfully phagocytose by PMVECs and entered its cytoplasm. At 12 h after culture of the third passage of PMVECs, compared with that in blank control group, the fluorescence intensity of reactive oxygen species of PMVECs in macrophage supernatant alone group was significantly increased (t=15.73, P<0.01); compared with that in macrophage supernatant alone group, the fluorescence intensity of reactive oxygen species of PMVECs in macrophage supernatant+ADSC-exosome group was significantly decreased (t=4.72, P<0.01). At 12 h after culture of the third passage of PMVECs, and the 8-OHdG positive fluorescence intensity of PMVECs in macrophage supernatant alone group was significantly increased; and compared with that in blank control group, the 8-OHdG positive fluorescence intensity of PMVECs in macrophage+ADSC-exosome supernatant group was between blank control group and macrophage supernatant alone group. At 12 h after culture of the third passage PMVECs, compared with that in blank control group, the permeability of PMVECs monolayer in macrophage supernatant alone group was significantly increased (t=6.34, P<0.01); compared with that in macrophage supernatant alone group, the permeability of PMVECs monolayer cells in macrophage supernatant+ADSC-exosome group was significantly decreased (t=2.93, P<0.05). Conclusions: Exosomes derived from ADSCs can ameliorate oxidative damage in mouse lung tissue, decrease the level of reactive oxygen species, 8-OHdG expression, and permeability of PMVECs induced by macrophage supernatant.

Abstract
At present, there is no special rapid cooling device for burn injury site in field battle training environment. To solve this problem, our research team designed a rapid cooling device for burns in field battle training. Based on the principle of rapid cooling of liquid nitrogen, the device monitors the temperature of the wound surface to regulate the release of liquid nitrogen so as to reduce the wound temperature. The device is simple in design, light in material, small in size, easy to carry, and can be used in various parts of the body. In addition, it is easy to operate and is expected to deliver a rapid cooling effect on the burn injury site to avoid the secondary damage caused by heat conduction to deep tissue.

Abstract
Hypertrophic scars and keloids are common sequelae after wound healing, with a high incidence, which seriously affect the patient's quality of life. However, there is still a lack of effective prevention and treatment methods, mainly because the pathogenesis of scars is not clear. Current research believe that inflammatory response plays a critical role in the process of scar formation, and through the researches on the mechanisms it is hopeful to find new potential therapeutic drug targets for the prevention and treatment of hypertrophic scars and keloids. This article mainly reviews the research progresses on the role and mechanism of inflammatory cytokines and inflammatory cells in the formation of hypertrophic scars and keloids, as well as drugs, microRNAs, and exosomes, etc., for the treatment of hypertrophic scars and keloids by inhibiting inflammatory response.

Abstract
Objective: To observe the effects of hand continuous passive motion (CPM) system combined with functional training and pressure gloves in treating early scar contracture after burn on the back of the hand. Methods: A retrospective cohort study was conducted in 43 patients who met the inclusion criteria and were admitted to the First Affiliated Hospital of Air Force Medical University from June 2017 to December 2019 with scar contracture after deep partial-thickness to full-thickness burn on the back of the hand. According to the treatment methods applied, 13 patients were enrolled into pressure glove alone group (9 males and 4 females, aged (31±6) years), 14 patients were enrolled into pressure glove+functional training group (11 males and 3 females, aged (30±5) years), and 16 patients were enrolled into pressure glove+functional training+CPM system group (10 males and 6 females, aged (29±5) years). All the patients in the three groups received skin grafting on the back of the hand. The corresponding rehabilitation treatment was started 6-8 days after wound healing, and the treatment lasted for 3 months. Before treatment and after 3 months of treatment, the total active motion range of the hand was measured to evaluate the motion range of the hand joint and the ratio of excellent and good was calculated; the Carroll upper limb function evaluation method was used to evaluate the upper limb function score, and the difference before and after treatment was calculated; the Vancouver Scar Scale was used to evaluate the scar score, and the difference before and after treatment was calculated. Data were statistically analyzed with chi-square test, Fisher's exact probability test, McNemar's exact probability test, one-way analysis of variance, Bonferroni correction, least significant difference test, Kruskal-Wallis test, and paired sample t test. Results: The ratio of excellent and good of the motion range of the hand joint of patients in pressure glove alone group, pressure glove+functional training group, and pressure glove+functional training+CPM system group were 2/13, 2/14, and 3/16 respectively before treatment, and 4/13, 6/14, and 14/16 respectively after 3 months of treatment. The ratio of excellent and good of the motion range of the hand joint of patients was significantly higher in pressure glove+functional training+CPM system group than in the other two groups after 3 months of treatment (P<0.05 or P<0.01). Compared with that before treatment, the ratio of excellent and good of the motion range of the hand joint of patients in pressure glove+functional training+CPM system group was significantly increased after 3 months of treatment (P<0.01). Before treatment, the upper limb function score and hand scar score of patients in the three groups were similar (F=0.598, 0.035, P>0.05). After 3 months of treatment, the upper limb function score of patients was significantly higher in pressure glove+functional training+CPM system group than in pressure glove alone group (P<0.05); the hand scar score of patients was significantly lower in pressure glove+functional training group and pressure glove+functional training+CPM system group than in pressure glove alone group (P<0.05 or P<0.01), and the hand scar score of patients was significantly lower in pressure glove+functional training+CPM system group than in pressure glove+functional training group (P<0.05). Compared with those before treatment, the upper limb function scores of patients were significantly increased (t=-5.295, -7.252, -15.342, P<0.01) and the hand scar scores of patients were significantly decreased (t=13.361, 16.982, 40.334, P<0.01) in pressure glove alone group, pressure glove+functional training group, and pressure glove+functional training+CPM system group after 3 months of treatment. The differences in upper limb function score and hand scar score of patients before and after treatment in pressure glove+functional training+CPM system group were significantly higher than those in pressure glove+functional training group and pressure glove alone group (P<0.05 or P<0.01). The differences in upper limb function score and hand scar score of patients before and after treatment in pressure glove+functional training group were significantly higher than those in pressure glove alone group (P<0.05). Conclusions: Hand CPM system combined with functional training and pressure gloves can significantly improve the motion range of hand joint in treating early scar contracture after burn on the back of the hand, with better restoration of hand function and improvement of hand scar. Its effect is better than routine rehabilitation treatment such as functional training, etc., which is worthy of clinical reference.

Abstract
Objective: To investigate the clinical effects of skin-stretching device (hereinafter referred to as stretcher) combined with vacuum sealing drainage (VSD) in repairing diabetic foot wounds. Methods: From March 2016 to January 2020, 25 patients with diabetic foot wounds were admitted to the First Affiliated Hospital of Air Force Medical University, including 18 males and 7 females, with age of 40 to 70 years. After debridement, intermittent VSD was performed for 3 to 10 days, with negative pressure value of -10.67 kPa. Then, the wound area was 5.0 cm×3.0 cm to 10.0 cm×7.0 cm. After infection control and detumescence, the wound was treated with stretcher for 3 to 5 days. The wound area after stretching ranged from 5.0 cm×0.3 cm to 10.0 cm×0.5 cm. The wound was closed with full-thickness suture. Two weeks after the suturing operation, the healing grade of the foot wound of patients was observed, and the serious complications such as recurrence of ulcer wound and gangrene on the foot, scar condition of the wound were observed during follow-up. Results: Two weeks after the suturing operation, the wounds of 23 patients were healed with grade A. Soft tissue infection ulcer relapsed in 2 patients during the stretch period. After anti-infection, thorough debridement, and VSD, the wounds were healed after another 16 days of stretch treatment. During the follow-up of 3 to 36 months, 23 patients had linear scar left on the stretch wounds, and the skin elasticity, color, sensation was similar to the surrounding normal tissue, and the limb mobility was good, and 2 patients had obvious scar hyperplasia. One patient had recurrence of diabetic foot and serious vascular occlusion and gangrene in the affected limb at follow-up of 10 months, which was treated with amputation of the lower leg. Conclusions: The use of stretcher combined with VSD in treating diabetic foot wound can avoid donor site injury, with healed wound achieving similar appearance to adjacent skin and satisfactory repair effects.

Abstract
Objective: To explore the choice of the donor site of flap and the repair method of secondary wound of flap donor site in tissue repair and reconstruction operation. Methods: From January 2014 to September 2018, 62 cases of scar contracture deformity, 15 cases of skin tumor, 20 cases of skin and soft tissue injury, and 25 cases of chronic wound were admitted to the Burn Center of People's Liberation Army of First Affiliated Hospital of Air Force Medical University, with 84 males and 38 females, aged from 3 to 89 years. Four repair strategies adopted for tissue repair and reconstruction and good repair of the donor site of flap were as follows: designing the flap rationally according to the condition around the wound or the size and shape of wound, choosing pre-expanded technique of the donor site of flap for repair of scar deformity optimally, making full use of the surrounding condition of flap donor site, and repaired with the distal flap, i. e. replacing the important site with secondary site. The donor site of flap was repaired by direct suture or peripheral flap and distal flap. The wound size of patients ranged from 3.0 cm×2.0 cm to 20.0 cm×18.0 cm, and the flap area ranged from 3.5 cm×2.0 cm to 25.0 cm×22.0 cm. The survival condition of flap, healing condition of donor site and recipient site, and follow-up condition of donor site and recipient site were recorded. Results: Wounds of 122 patients were repaired with a total of 148 flaps designed by the above four repair strategies. All the flaps survived well, and the wound and flap donor site healed well. Follow-up for 3 to 36 months showed that the shape and function of recipient site and flap donor site were satisfactory. Conclusions: According to the specific condition of the wound and anatomical structure of the surrounding tissue of flap donor site, overall surgical design with flexibility and personalization can achieve effects of good repair of the wound and reduce the secondary damage of flap donor site.

Abstract
OBJECTIVE To explore the risk factors, clinical characteristics, precaution and treatment of hyper perfusion syndrome (HPS) after carotid artery stenting (CAS). METHODS From September 2014 to March 2018, the clinical data of 226 patients with severe carotid stenosis (70%-99%) treated with carotid artery stenting (CAS)at Department of Interventional Radiology and Vascular Surgery, Peking University Third Hospital, were analyzed retrospectively.Five of them developed HPS after CAS.The relationship between the clinical baseline data, imaging characteristics, perioperative management and HPS were assessed. RESULTS In this group, 5 patients of them (2.21%, 5/226) developed HPS after CAS, and 2 patients of them (0.88%, 2/226) were hyper perfusion induced intracranial hemorrhage (HICH). The 5 patients consisted of 4 men and 1 woman whose age ranged from 58 to 74 years. The symptoms of HPS occurred within 4 hours to 3 days after CAS. Among the 5 cases, the clinical manifestations were that 2 cases with headache, 1 case with delirium,1 case with hemiparesis of left limbs, and 1 case with coma(died ultimately).The main manifestations of case 1 and case 2 were headache in the frontal parietal temporal region of the operative side, accompanied by nausea and vomiting. The symptoms were relieved after blood pressure lowering treatment and mannitol dehydration. The main manifestations of case 3 were excitement and delirium. The symptoms were relieved by a small dose of sedatives, also with blood pressure lowering treatment and mannitol dehydration. The initial symptoms of case 4 were excitement and delirium, accompanied by mild headache of the operative side, and hemiplegia of the contralateral limb occurred within a short time. The main manifestation of case 5 was severe headache and went into deep coma within a short time. This patient died of massive cerebral hemorrhage ultimately. CONCLUSION HPS is an uncommon but serious complication after CAS. Improving our understanding and heightening vigilance of HPS is necessary. The earlier diagnosis, the earlier treatment.

Abstract
Objective: To compare the efficacy and safety of pulsed dye laser (PDL) and ultra-pulsed fractional carbon dioxide laser (UFCL) in treating hypertrophic scars after burns. Methods: Two hundred and twenty one patients with hypertrophic scar after burns conforming to the study criteria were admitted to our unit from February 2015 to October 2017, and their data were retrospectively analyzed. Patients were divided into group PDL (n=122) and group UFCL (n=99) according to the treatment method. Patients in group PDL were treated with PDL once every 3-4 weeks. Patients in group UFCL were treated with UFCL once every 6-12 weeks. Patients in both groups were treated until 12 months after having scar. Scars were scored by Vancouver Scar Scale (VSS) before and after treatment. Patients' pain was evaluated by Visual Analogue Scale (VAS) method before and after treatment. Blood flow in scar was monitored and recorded before treatment and in treatment months 6 and 12. Satisfaction degree of patients was recorded 3-6 months after treatment, and the satisfaction rate was calculated. Adverse reactions including duration of erythema/purpura, VAS in treatment, and loss of working time were recorded. Data were processed with one-way analysis of variance, t test, and Chi-square test. Results: (1) VSS scores of patients in groups PDL and UFCL after treatment were significantly lower than those before treatment in the same group (t=11.34, 12.77, P<0.05). The decreasing VSS scores of patients after treatment in groups PDL and UFCL were (5.8±1.1) and (6.0±1.4) points, respectively, and there was no statistically significant difference between the two groups (t=1.91, P>0.05). (2) VAS of patients in groups PDL and UFCL after treatment were significantly lower than those before treatment in the same group (t=7.12, 5.23, P<0.05). The decreasing VAS of patients after treatment in groups PDL and UFCL were (4.0±0.6) and (3.2±1.3) points, respectively, and there was no statistically significant difference between the two groups (t=1.93, P>0.05). (3) Scar blood flow of patients in group PDL in treatment months 6 had no obvious change compared with that before treatment (t=1.59, P>0.05), while that in treatment months 12 significantly decreased compared with that before treatment and that in treatment months 6 (t=3.17, 6.96, P<0.05). Scar blood flow of patients in group UFCL in treatment months 6 significantly increased compared with that before treatment (t=6.01, P<0.05), while that in treatment months 12 significantly decreased compared with that in treatment months 6 (t=4.52, P<0.05), but had no obvious change compared with that before treatment (t=0.92, P>0.05). (4) The satisfaction degree of patients in group PDL was 80.3% (98/122), which in group UFCL was 76.8% (76/99), and there was no statistically significant difference between the two groups (χ(2)=0.97, P>0.05). (5) The duration of erythema/purpura of patients in group PDL was (5.2±0.7) d, significantly shorter than (6.1±0.5) d in group UFCL (t=2.49, P<0.05). The VAS of patients in group PDL during treatment was (1.9±0.9) points, significantly lower than (4.7±0.4) points in group UFCL (t=4.85, P<0.05). Loss of working time of patients in group UFCL was (9.17±0.72) d, which was significantly longer than (3.96±0.23) d in group PDL (t=3.17, P<0.05). Conclusions: PDL and UFCL have definite effects on hypertrophic scar, while PDL with light pain, minor wound, and fast recovery time, is safe and effective for treatment of early hypertrophic scar and worthy of clinical promotion and application, especially for children and patients with poor pain tolerance.

Abstract
Objective: To observe the effects of the method of combining free superficial temporal fascia flaps with skin grafts in repairing deep wounds in posterior ankle region of extensively burned patients. Methods: From September 2013 to February 2017, 11 extensively burned patients with deep tissue defects in posterior ankle region were treated in our unit. Two patients had tissue defects in bilateral posterior ankle regions. The wound sizes ranged from 5.8 cm×4.6 cm to 11.7 cm×5.2 cm. Free superficial temporal fascia flaps with the same sizes as the wounds were designed and resected to repair wounds in posterior ankle regions after debridement. The proximal end of superficial temporal veins and posterior tibial veins were performed with end-to-end anastomosis, and superficial temporal arteries and posterior tibial arteries were performed with end-to-side anastomosis. Skin grafts were resected to cover the superficial temporal fascia flaps according to patients' condition of donor sites. The donor sites were sutured directly. Results: All fascial flaps in 11 patients survived, while 2 skin grafts had partial necrosis, and they healed after secondary skin graft. All patients were followed up for 6 to 13 months, and the shape and function of the operation sites in all patients recovered well. Conclusions: The method of combining free superficial temporal fascia flaps with skin grafts can repair deep wounds in posterior ankle regions of extensively burned patients. It has the advantages of good appearances in the recipient sites, strong resistances to infection of fascia flaps, minimal damages to the donor sites, short course of disease, and good prognosis of patients.

Abstract
This study aimed to examine the temporal (hourly within a day and daily over the long term) effects of monensin on CH4 emissions, ruminal fermentation, and in situ alfalfa degradation in dairy goats during dietary monensin supplementation by controlling the confounding effects of feed intake and ambient temperature. Six ruminally cannulated dairy goats were used, and they were housed in environmental chambers and fed a restricted amount of ration throughout the experiment. The experiment included a baseline period of 20 d followed by a treatment period of 55 d with 32 mg of monensin/d. During the whole experiment, CH4 production was measured every 5 d, whereas fermentation characteristics and in situ alfalfa degradation were analyzed every 10 d. The CH4-depressing effect of monensin was time dependent on the duration of treatment, highly effective at d 5 but thereafter decreased gradually until d 55 even though CH4-suppressing effect still remained significant. The decreasing effects of monensin on ruminal acetate proportion and acetate to propionate ratio also faded over days of treatment, and the acetate proportion returned up to the pre-supplementation level on d 50. Monensin supplementation elevated ruminal propionate proportion and decreased the effective ruminal degradability of alfalfa NDF, but both measurements tended to recover over time. The postprandial increase rate of hourly CH4 emissions was reduced, whereas that of propionate proportion was enhanced by monensin supplementation. However, the postprandial responses to monensin in CH4 emission rates, ruminal VFA profiles, and in situ degradation kinetics declined with both hours after feeding and days of treatment. Our results suggest that the CH4-suppressing effect of monensin supplementation in goats was attributed to reductions in both ruminal feed degradation and acetate to propionate ratio, but those reductions faded with time, hours after feeding, and days of treatment.

Abstract
Perioperative stroke is cerebral infarction occurring in the perioperative period. The incidence of perioperative stroke in non-cardiac, and non-neurologic surgery is about 0.7%, but the mortality can be as high as 26% to 40%. The outcome of the patients with perioperative stroke can be disastrous. Here we report a case of perioperative ischemic stroke that occurred after surgery of lumbar decompression and pedical screw fixation. A 76-year-old female admitted to our hospital because of lumbar spinal stenosis. Her medical history included hypertension and diabetes for ten years. Her personal history included a smoking history of 60 years by 2 cigarettes per day, not quitting. Her carotid artery ultrasound showed multiple low echo plaques on the right side and multiple high echo plaques on the left side of the carotid artery, but without distinct stenosis. Other examinations and tests showed no distinct abnormality. She went on a lumbar decompression and pedical screw fixation uneventfully. The blood loss was 400 mL and autologous blood transfusion 150 mL. The arterial blood pressure (ABP) maintained during 100-130 mmHg/60-80 mmHg (1 mmHg=0.133 kPa). Sixty minutes after she recovered from general anesthesia, the patient developed symptoms of slurred speech and right limbs weakness. The anesthesio-logist evaluated the patient immediately with National Institute of Health Stroke Scale (NIHSS). The NIHSS score was 11 and a stroke was highly suspected. The acute stroke team was therefore initiated and fast responded. Within 4 h, digital subtraction angiography (DSA) was proceeded, which showed the M1 segment of the left middle cerebral artery was occluded and the local stenosis of her right middle cerebral artery was up to 80%. After the successful embolectomy by Solitaire stent, the left middle cerebral artery reflowed and the forward blood flow was thrombolysis in myocardial infarction (TIMI) grade 3. The patient was discharged after 33 days after the surgery with a NIHSS of 9. Our case provides an example that an acute stroke team that included the department of anesthesiology can be beneficial to the patients' perioperative strokes. During the perioperative period, anesthesiologists should be included into the acute stroke team, because anesthesiologists and anesthesia nurses might be first observers of those early onset strokes. Our case also put forward this thought that a standard peri-operative stroke evaluation tool, like NIHSS, should be discussed and applied to facilitate and accelerate the initiation of perioperative acute stroke team.

METHODS The original DICOM format image data from a patient with vertebrobasilar dolichoectasia (VBD), were imported by the Mimics software directly,and the 3D Objects were constructed.The simulation of model was made with Ansys software, the hemodynamic parameters such as streamlines, wall shear stress (WSS) and wall pressure were described. RESULTS There was stable laminar flow in proximal basilar artery and was no blood flow mixed by bilateral vertebral artery.However, Spiral flows were appeared in distal tortuous basilar artery. The low WSS regions in the vertebrabasilar junction section and inferior segment of basilar artery were coincide with the high wall pressure regions.It could be speculated the initial growth regions might be located in the vertebrabasilar junction section and inferior segment of basilar artery.Local regions with low WSS and high wall pressure might be associated with the occurrence and development of VBD. CONCLUSION CFD numerical simulation maybe can provide a theoretical basis for the role of hemodynamic factors in occurrence and development of VBD.

Abstract
OBJECTIVE To study the importance of the internal iliac artery (IIA) during the endovascular aneurysm repair (EVAR) for abdominal aortic aneurysm (AAA). METHODS Forty-six consecutive cases of AAA treated by EVAR were retrospectively analyzed. The complications after exclusion of the IIA were analyzed. RESULTS The bilateral IIAs were reserved in 18 cases, in which the follow-up was achieved in 16 cases and no complication was observed. The IIAs were excluded in 28 (60.9%) cases, in which the bilateral, right and left IIAs were excluded in 7 (15.2%), 14 (30.4%) and 7 (15.2%) cases respectively. The follow-up was achieved in 26 cases. Buttock claudication was observed in 12 (46.2%) cases, altered bowel habit was observed in 8 (32.0%) cases, erectile dysfunction was observed in 3 (12.0%) cases, and bloody stool was observed in 2 (8.0%) cases. Comparing the bilateral and unilateral IIA exclusions, the rates of buttock claudication were 50.0% vs. 45.0%, altered bowel habit 33.3% vs. 31.6%, and erectile dysfunction 33.3% vs. 5.3% respectively. And the average duration of buttock claudication of bilateral IIAs exclusion (8.3 months) was longer than that of unilateral exclusion (4.7 months). Moreover, comparing the left and right IIA exclusions, the rates of buttock claudication were 57.1% vs. 38.5%, altered bowel habit 57.1% vs. 16.7%, and bloody stool 28.6% vs. 0 respectively. And the average duration of buttock claudication of left IIA exclusion (6.0 months) was longer than that of right exclusion (3.7 months). CONCLUSION The IIAs, especially the left IIA, should be reserved during the EVAR for AAA.
