Microcirculatory disorders are important pathological and physiological changes in high-voltage electric burns, playing an important role in the occurrence and development of progressive injury and complications of high-voltage electric burns. High-voltage electric burns can cause microcirculatory disorders not only in the wounds, but also in distant tissue and organs; it can not only cause damage to the structure and function of microvasculature, but also cause abnormalities in microcirculation hemodynamics and cell rheology. Understanding the characteristics and changing patterns of microcirculatory disorders in high-voltage electric burns, and using appropriate treatment methods to improve microcirculation, are of great significance for promoting wound healing and effectively preventing relevant complications in high-voltage electric burns. This article systematically elaborates on the characteristics of microcirculatory disorders after high-voltage electric burns, summarizes the clinical diagnosis and treatment methods of microcirculatory disorders after high-voltage electric burns, and provides new ideas for the comprehensive treatment of high-voltage electric burns.

Objective:To explore the characteristics of renal oxidative stress injuries in rats with high-voltage electric burns and the intervention effects of breviscapine.Methods:This study was an experimental study. One hundred and sixty 8-10-week-old male Sprague Dawley rats were divided into sham injury group, electric burn group, saline group, low breviscapine group, middle breviscapine group, and high breviscapine group, with 60 rats in each of the sham injury group and electric burn group, 10 rats in each of the other 4 groups, respectively. The rats in sham injury group and electric burn group were divided into 10 rats at each time point, including post injury hour (PIH) 0 (immediately), 8, 24, 48, and 72, and post injury week (PIW) 1. The rats in sham injury group were not conducted with electrical current to cause sham injury. The rats in the other 5 groups were caused high-voltage electric burns. The rats in sham injury group and electric burn group were not treated after injury. The rats in saline group, low breviscapine group, middle breviscapine group, and high breviscapine group were intraperitoneally injected with 5 mL/kg normal saline or 0.4, 1.6, and 4.0 g/L breviscapine, repeated every 24 h until PIH 72. After the model was successfully made, 14 rats died, including 1, 2, 2, and 1 rat (s) at PIH 24, 48, and 72 and PIW 1 in electric burn group, 4, 1, 2, and 1 rat (s) at PIH 72 in saline group, low breviscapine group, middle breviscapine group, and high breviscapine group, respectively. The kidney tissue collected from rats in the 6 groups was weighed and the kidney/body weight ratio was calculated. The left upper pole tissue of kidney was collected from each 4 rats in sham injury group, and in electric burn group at PIH 8, 24, 48, and 72 and PIW 1, and in saline group, low breviscapine group, middle breviscapine group, and high breviscapine group at PIH 72. The renal tubular and renal interstitial injury was evaluated by a semi-quantitative histological scoring system after hematoxylin-eosin staining. The inferior vena cava blood samples were collected from rats in the 6 groups to measure the serum creatinine levels via sarcosine oxidase method, and serum urea nitrogen levels via urease method. The right renal cortices were collected from rats in the 6 groups to measure the catalase (CAT) activity in the supernatant of renal tissue via molybdic acid method, and the levels of advanced oxidation protein product (AOPP) and Klotho protein in the supernatant of renal tissue via enzyme-linked immunosorbent assay.Results:At PIH 8, 48, and 72 and PIW 1, the kidney/body weight ratios of rats in electric burn group were significantly higher than those in sham injury group (with t values of -0.52, -3.75, -4.05, and -2.25, respectively, P<0.05).

Objective:To observe any impact of the repeated application of high-frequency peripheral magnetic stimulation (rPMS) on the recovery of motor function among hemiplegic survivors of an intracerebral hemorrhage. Also to explore the therapeutic mechanism involved.Methods:Sixty-two hemiplegic survivors of an intracerebral hemorrhage were randomly assigned to an observation group or a control group, each of 31. Both groups received standard medical treatment and early rehabilitation, but the observation group also received high-frequency rPMS applied to their upper and lower limbs. Before and after two weeks of the treatment, everyone′s motor functioning was assessed using the Fugl-Meyer Assessment (FMA). Walking ability was quantified using functional ambulation classification (FAC). And ability in the activities of daily living was rated using the modified Barthel Index (MBI). The amplitudes and latencies of motor evoked potentials (MEPs) induced by transcranial magnetic stimulation and recorded from the abductor pollicis brevis of the affected side were also analyzed..Results:After the treatment, significant improvement was observed in both groups′ upper and lower limb FMA scores, MBI scores, FAC grades, and in their MEP amplitudes and latencies. On average, however, the observation group′s results were significantly better than those of the control group. Moreover, no significant adverse reactions were found in either group during the treatment.Conclusions:Early rPMS intervention significantly enhances the recovery of limb function after an intracerebral hemorrhage, possibly through its modulation of cortical excitability.

High-voltage electric burn is one of burns that can cause severe damages to tissue and organs. Clinically, progressive injury in high-voltage electric burns is a key pathological change that affects the level of amputation and the success rate of treatment. At present, the exact definition and mechanism of progressive injury in high-voltage electric burns have not been elucidated, and the clinical treatment is mainly symptomatic treatment. Relevant research data on the mechanism and treatment of progressive injury in high-voltage electric burns are lacking. This paper analyzes and summarizes the mechanism, diagnosis, treatment, and common outcome of progressive injury in high-voltage electric burns, and provides a reference for the mechanism research, clinical diagnosis and treatment of progressive injury in high-voltage electric burns.

Difference of chronotypes makes influence to cognitive performance of individuals in routine duties. In this paper, 55 subjects with different chronotypes were subjected to continuous sleep deprivation for 30 h by using the constant routine protocol, during which core body temperature was measured continuously, and subjective sleepiness self-rating and the performance of selective attention were measured hourly. The results showed that the phase difference of core body temperature has no significant difference, yet the amplitude and term difference among the three chronotypes are significant. There was an advance in phase between subjective sleepiness self-rating and core body temperature, and the self-rating sleepiness of evening type came the latest, and the self-rating sleepiness of morning type dissipated the fastest. The response time of selective attention showed a 2 h phase delay with subjective sleepiness self-rating. And the analysis of core body temperature showed that the later the chronotype was, the greater the phase delay was. The correct rate of selective attention of different chronotypes were inconsistent with delay of subjective sleepiness self-rating and core body temperature. We provide reference for industry, aviation, military, medical and other fields to make a more scientific scheduling/ shifting based on cognitive performance characteristics of different chronotypes.

(3) Changing trend of the volume of urine output, levels of lactic acid, levels of enteral nutrient intake and the sequential organ failure score in patients with different treatment outcomes. The volume of urine output, levels of lactic acid, levels of enteral nutrient intake and the sequential organ failure score in surviving patients during hospitalization were (0.29±0.10)mL/(kg·h), (4.2±0.6)mmol/L, 0.0 kcal/(kg·d) and 9.4±3.4 before the treatment with open abdomen technique and (2.22±0.15)mL/(kg·h), (1.9±0.7)mmol/L, (20.7±2.9)kcal/(kg·d) and 3.7±2.2 at postoperative 168 hours. The above indicators in dead patients during hospitalization were (0.28±0.08)mL/(kg·h), (5.2±0.5)mmol/L, 0.0kcal/(kg·d) and 11.5±2.4 before the treatment with open abdomen technique and (0.28±0.09)mL/(kg·h), (7.7±0.8)mmol/L, (4.6±1.8)kcal/(kg·d) and 12.4±2.1 at postoperative 168 hours. There were significant differences in time effects in the above indicators in surviving patients and dead patients before and after the treatment with open abdomen technique ( Ftime=425.57, 188.59, 394.84, 37.52, P<0.05). There were interactive effects between the above indicators and the treatment outcome at different time points ( Finteraction=383.14, 233.04, 169.83, 36.61, P<0.05). There were signifi-cant differences in the change trends of the above indicators between the surviving patients and the dead patients during hospitalization ( Fgouprs=2 739.56, 877.98, 542.05, 240.85, P<0.05). (4) Influen-cing factors for prognosis of patients. Results of univariate analysis showed that age, sequential organ failure score, duration of ACS before surgery, procalcitonin, lactic acid, postoperative high-order intestinal fistula, abdominal hemorrhage, duration of postoperative acute gastrointestinal injury, duration of continuous renal replacement therapy, duration of vasoactive drugs therapy, early abdominal closure were related factors influencing prognosis of patients under-going treatment with open abdomen technique ( hazard ratio=1.07, 1.18, 1.39, 1.16, 8.25, 12.26, 2.83, 1.29, 1.56, 1.41, 0.02, 95% confidence interval as 1.00-1.15, 1.45-2.27, 1.22-1.57, 1.02-1.32, 1.75-38.90, 7.37-41.23, 1.16-6.93, 1.22-1.37, 1.23-1.99, 1.08-1.84, 0.00-0.16, P<0.05). Results of multivariate analysis showed that extended duration of ACS before surgery, postoperative high-order intestinal fistula and extended duration of postoperative acute gastrointestinal injury were independent risk factors influencing prognosis of patients undergoing treatment with open abdomen technique ( hazard ratio=1.05, 7.95, 1.17, 95% confidence interval as 1.01-1.32, 2.05-30.87, 1.13-1.95, P<0.05) and early abdominal closure was an independent protective factor ( hazard ratio=0.10, 95% confidence interval as 0.01-0.89, P<0.05). Results of Spearman correlation analysis showed that duration of ACS was positively correlated with sequential organ failure score before surgery ( r=0.71, P<0.05). Conclusions:Open abdomen technique is effective for acute pancreatitis with ACS. Extended duration of ACS before surgery, postoperative high-order intestinal fistula and extended duration of postoperative acute gastrointestinal injury are independent risk factors for prognosis of patients during hospitalization and early abdominal closure is an independent protective factor.

Objective: To investigate the value of transrectal ultrasonography(TRUS) in the preoperative diagnosis and tumor T-staging of anorectal malignant melanoma(ARMM). Methods: The clinical and ultrasound data of 19 patients(22 lesions) with ARMM confirmed by pathology from February 2008 to Apirl 2019 in Fujian Medical University Affiliated Union Hospital were collected. TRUS was performed within one week before pathological examination. The sonographic features were summarized, ultrasonic typing was performed according to the lesion size and growth pattern, and the accuracies of preoperative ultrasound diagnosis and tumor staging were analyzed. Results: Among the 22 lesions, 63.64%(14/22) were with a distance of ≤3 cm between the anal verge and the lower margin of tumor, 68.18%(15/22) with regular shape, 81.82%(18/22) with clear boundary, and 63.64%(14/22) with Adler blood flow grading from Ⅱ to Ⅲ. The preoperative TRUS diagnostic coincidence rate was 73.68%(14/19), and the tumor T-staging accuracy was 75%(12/16), respectively. Conclusions TRUS exhibits certain sonographic characteristics, with high preoperative diagnosis rate and tumor T-staging accuracy in anorectal malignant melanoma, which is of great guiding significance for clinical diagnosis and treatment.

Objective:To evaluate the influence of the sleeve lengths and implant lengths on accuracy of static computer-assisted implant surgery (sCAIS).Methods:Twenty-eight models of bilateral mandibular single tooth loss were included. Fifty-five implants were placed under the guidance of sCAIS (Straumann Bone Level 4.1 mm×10 mm). According to the height of metal sleeve of static guide plate, 55 implants were divided into 11 groups (free hand group, 1 mm group, 2 mm group, 3 mm group, 4 mm group, 5 mm group, 6 mm group, 7 mm group, 8 mm group, 9 mm group, 10 mm group), with 5 implants in each group. Eight research models were included. Group with 5 mm sleeve guides were used to place implants of different length, (Straumann Bone Level width 4.1 mm, height was 8 mm, 10 mm and 14 mm), 5 implants in each group. Eighteen patients with mandibular single tooth loss were included in the Department of Oral Implantology, Tianjin Stomatological Hospital from October 2018 to June 2019. There were 10 males and 8 females, 18-46(33.7±7.9) years old. A total of 18 implants were implanted and divided into 3 groups (free hand group, 3 mm group and 5 mm group) with 6 implants in each group. Digital software was used to compare the implant positions before and after implantation. Non-parametric Kruskal-Wallis test or one-way ANOVA were used to analyze the results.Results:There was no significant difference in implant vertical deviation between different sleeve height groups (1-10 mm) and free hand group, but the neck deviation in free hand group[(1.04±0.13) mm] was significantly higher than that in different sleeve height groups (1-10 mm) ( P<0.05). The tip deviations of free hand group, 1 mm group and 2 mm group [(1.32±0.43), (0.83±0.10) and (0.78±0.11) mm, respectively] was significantly higher than that of 10 mm group [(0.31±0.14) mm]( P<0.05). The angle deviation of free hand group and 1 mm group (3.99°±0.85° and 2.59°±0.69°), respectively] was significantly higher than that of 10 mm group (0.61°±0.03°) ( P<0.05). The tip deviations of implants in the 14 mm group [(0.83±0.22) mm] was significantly higher than that in the 8 mm and 10 mm groups [(0.44±0.07) and (0.49±0.06) mm, respectively]. Clinical studies showed that there was no significant difference in neck deviation, tip deviation and angle deviation between 3 mm group and 5 mm group ( P>0.05), but deviations were significantly lower than those in free hand group ( P<0.05). Conclusions:The length of the sleeves has significant influence on the accuracy of the surgical guide. There was no significant difference in accuracy of the implant guide with 3 mm or 5 mm metal sleeves. The vitro study has some limitations and needs further systematic research.

Electrical burn is a special type of injury with complex injury mechanism, which is one of the difficult issues in the treatment of burn injuries. It not only seriously damages the tissue and organs of body, but also significantly affects the mental health of patients. Many patients with electrical burn simultaneously suffer physical and mental agonies causing increased difficulty in treatment and prolonging the time of recovery. Some of them may experience loss of ability to work or even death due to the mental disorders, despite successful patch-up of their physical injuries. Therefore in treating electrical burn, the psychotherapy and rehabilitation of patients should be closely monitored in addition to the reconstruction of their physical damage.

Objective:To explore the effect of high-voltage electrical burn on platelet function and rheological behavior in rats and the interventive effect of Xuebijing.Methods:A total of 280 Sprague Dawley rats of clean grade (aged 8-10 weeks, male and female unlimited) were divided into sham injury group, simple electrical burn group, electrical burn+ saline group, and electrical burn+ Xuebijing group according to the random number table, with 70 rats in each group. Rats in sham injury group were not conducted with electrical current to cause sham injury. Rats in the other three groups were given electrical current with output voltage of 2 kV and current intensity of (1.92 ± 0.24) A for 3 s, which caused high-voltage electrical burn wounds, each with an area of 1 cm×1 cm distributed in the left forelimb at the current inlet and the right hindlimb at the current outlet respectively. Rats in sham injury group and simple electrical burn group were not treated after injury. At post injury minute 2 and on post injury day (PID) 1, 2, 3, 4, 5, and 6, rats in electrical burn+ saline group and electrical burn+ Xuebijing group were intraperitoneally injected with 6 mL/kg saline and 6 mL/kg Xuebijing, respectively. Survival conditions of rats were recorded during the experiment. At 15 min before injury and at post injury hour (PIH) 1, 8, 24, 48, 72, and on PID 7, 10 rats in each group were respectively selected according to the random number table to sacrifice after collection of 5 mL blood under the direct vision of heart. Blood in the volume of 0.05 mL from each rat was taken to make blood smear, and platelet aggregation number was counted under 400 fold field of view using multiple projection microscope. The remaining blood samples were centrifuged to collect supernatant, and the content of platelet-derived growth factor (PDGF), thrombopoietin (TPO), and platelet activating factor (PAF) was detected by enzyme-linked immunosorbent assay. Data were statistically analyzed with analysis of variance for factorial design and Student-Newman-Keuls method.Results:All rats in sham injury group and simple electrical burn group survived during the experiment. One rat in electrical burn+ saline group died on PID 6, and one rat on PID 5 and one rat on PID 6 died in electrical burn+ Xuebijing group. The levels of all indexes among the 4 groups were close at 15 min before injury. The serum content of PDGF, TPO, and PAF and platelet aggregation number of rats in the three electrical burn groups at all time points after injury were higher or more than those in sham injury group, and the first three indexes reached the peak at PIH 8. The serum platelet aggregation number of rats in simple electrical burn group reached the peak at PIH 48, and that in electrical burn+ saline group and electrical burn+ Xuebijing group reached the peak at PIH 72. Among them, the serum content of PDGF of rats in electrical burn+ Xuebijing group at PIH 48, 72 and on PID 7 ((12.8±4.0), (11.6±4.4), (11.0±3.6) ng/mL, respectively) was close to that in sham injury group ((10.4±2.0), (10.4±2.5), (9.8±3.3) ng/mL, respectively, P>0.05). The serum content of TPO of rats in electrical burn+ Xuebijing group at PIH 24, 72 and on PID 7 ((200±52), (192±36), (193±32) ng/mL, respectively) was close to that in sham injury group ((182±30) , (184±41), (183±33) ng/mL, respectively, P>0.05). The serum content of PDGF, TPO, and PAF and platelet aggregation number of rats in electrical burn+ Xuebijing group at every time point after injury was generally lower or less than that in electrical burn+ saline group and simple electrical burn group. Conclusions:Application of Xuebijing treatment after high-voltage electrical burn can decrease the content of PDGF, TPO, and PAF in the serum and reduce the number of platelet aggregation, thereby inhibit platelet activation and improve platelet rheology.
