ABSTRACT
Objective:To investigate the relationship between change of serum D-dimer (D-D), soluble vascular cell adhesion molecule 1 (sVCAM-1), P-selectin and thrombosis after limb fracture surgery.Methods:289 patients with limb fractures who were treated in the emergency department of Shulan (Hangzhou) Hospital from January 2021 to January 2022 were selected as the study subjects. They were divided into deep vein thrombosis (DVT) group ( n=62) and non-DVT group ( n=227) according to whether DVT occurred after operation. The levels of prothrombin time (PT), activated partial prothrombin time (APTT), D-D, sVCAM-1 and P-selectin were measured before and after operation in all patients. The levels of PT, APTT, D-D, sVCAM-1 and P-selectin were compared between DVT group and non-DVT group. Logistic sequential stepwise regression analysis was used to analyze the risk factors of postoperative thrombosis in patients with limb fractures. Results:There was no statistically significant difference in PT and APTT between 289 patients with limb fractures after operation and before operation (all P>0.05), while the levels of serum D-D, sVCAM-1 and P-selectin after operation were higher than that before operation (all P<0.05). There was no significant difference in general data between DVT group and non-DVT group (all P>0.05); There was no statistically significant difference in PT and APTT before and after operation between DVT group and non-DVT group (all P>0.05). The levels of serum D-D, sVCAM-1 and P-selectin before and after operation in DVT group were higher than those in non-DVT group (all P<0.05). Logistic sequential stepwise regression analysis showed that high levels of D-D, sVCAM-1 and P-selectin were risk factors for thrombosis after limb fracture surgery (all P<0.05). Conclusions:High levels of D-D, sVCAM-1 and P-selectin are risk factors for thrombosis after limb fracture surgery.
ABSTRACT
@#AIM: To analyze the correlation between levels of serum soluble intercellular adhesion molecule-1(sICAM-1), soluble vascular cell adhesion molecule-1(sVCAM-1)and the severity of thyroid-associated ophthalmopathy(TAO). <p>METHODS: A total of 120 patients with TAO admitted to the hospital from August 2016 to March 2018 were selected and included in the study. According to the clinical activity score(CAS), the patients were divided into active stage group and inactive stage group. According to the severity, they were divided into mild group, moderate group and severe group. There were 90 healthy persons were selected as the control group at the same time. The general data, serum sICAM-1 and sVCAM-1 levels were compared among groups and the correlation of sICAM-1 and sVCAM-1 levels with the severity of TAO was analyzed. <p>RESULTS: There were no significant differences in the clinical basic data of patients in between the different clinical active stage groups and the control group, and between the different severity groups and the control group(<i>P</i>>0.05). The levels of serum sICAM-1 and sVCAM-1 in the active stage group were significantly higher than those in the inactive stage group and the control group(<i>P</i><0.01). The levels of serum sICAM-1 and sVCAM-1 in active stage patients of different severity groups were significantly higher than those in inactive stage patients and of control groups(<i>P</i><0.01). There were no significant differences in levels of serum sICAM-1 and sVCAM-1 in inactive stage patients of different severity groups. The levels of serum sICAM-1 and sVCAM-1 in active stage patients of different severity groups increased gradually with the severity of the disease. There was no significant correlation between levels of serum sICAM-1 and sVCAM-1 in inactive stage patients and the severity of disease(<i>r</i>=0.102, 0.095, <i>P</i>=0.135, 0.167). Levels of serum sICAM-1 and sVCAM-1 in active stage patients were positively correlated to severity of disease(<i>r</i>=0.695, 0.824, <i>P</i>=0.005, 0.002).<p>CONCLUSION: The levels of serum sICAM-1 and sVCAM-1 in inactive patients will not increase with the severity of the disease. However, the levels in patients with active disease will increase with the severity of the disease, which can be used for clinical diagnosis and staging of TAO and monitoring of the prognosis.

ABSTRACT
Objective@#To investigate influences of high-voltage electrical burns on microcirculation perfusion on serosal surface of small intestine of rats and the interventional effects of pentoxifylline (PTX).@*Methods@#Totally 180 SD rats were divided into sham injury group, simple electrical burn group, and treatment group according to the random number table, with 60 rats in each group. The electrical current was applied to the outside proximal part of left forelimb of rats and exited from the outside proximal part of right hind limb of rats. Rats in simple electrical burn group and treatment group were inflicted with high-voltage electrical burn wounds of 1cm×1cm at current entrances and exits, with the voltage regulator and experimental transformer. Rats in sham injury group were sham injured through connecting the same equipments without electricity. At 2 min post injury, rats in sham injury group and simple electrical burn group were intraperitoneally injected with 2 mL normal saline, and rats in treatment group were injected with 2 mL PTX injection (50 mg/mL). At 15 min before injury and 5 min, 1 h, 2 h, 4 h, and 8 h post injury, 10 rats in each group were selected to collect blood of heart respectively. Serum were separated from the blood to determine the level of soluble vascular cell adhesion molecule-1(sVCAM-1) with enzyme-linked immunosorbent assay method. The number of adhesional leukocyte in mesenteric venule of rats was determined with Bradford variable projection microscope system. The microcirculation perfusion on serosal surface of small intestine of rats was detected with laser Doppler perfusion imager. Data were processed with analysis of variance of factorial design and LSD test.@*Results@#(1) At 5 min, 1 h, 2 h, 4 h, 8 h post injury, the serum content of sVCAM-1 in rats of simple electrical burn group were (8 502±1 158), (11 793±3 310), (9 960±2 146), (9 708±1 429), (7 292±1 386) ng/mL respectively, higher than that in sham injury group and treatment group [ (1 897±946), (1 882±940), (1 882±938), (1 888±946), (1 884±942) ng/mL, and (6 840±1 558), (6 742±2 465), (5 625±2 593), (2 373±1 463), (5 187±2 797) ng/mL, respectively, with P values below 0.001]. The serum content of sVCAM-1 in rats of sham injury group and treatment group at all time points post injury, except 4 h post injury of treatment group, was higher than that of the same group at 15 min before injury (with P values below 0.001). (2) At all time points post injury, the number of adhesional leukocyte in mesenteric venule of rats in simple electrical burn group was higher than that in sham injury group and treatment group (with P values below 0.001). The number of adhesional leukocyte in mesenteric venule of rats in simple electrical burn group and treatment group at all time points post injury was higher than that of the same group at 15 min before injury (with P values below 0.001). (3) At all time points post injury, the microcirculation perfusion on serosal surface of small intestine of rats in simple electrical burn group was lower than that in sham injury group and treatment group (with P values below 0.001). The microcirculation perfusion on serosal surface of small intestine of rats in simple electrical burn group and treatment group at all time points post injury was lower than that of the same group at 15 min before injury (with P values below 0.001).@*Conclusions@#High-voltage electrical burns can increase the serum content of sVCAM-1, the number of adhesional leukocyte in mesenteric venule, and reduce microcirculation perfusion on serosal surface of small intestine of rats. PTX can inhibit secretion of serum sVCAM-1, reduce the number of adhensional leukocyte in mesenteric venule to alleviate microcirculation disturbance caused by high-voltage electrical burns.

The hs-CRP, sVCAM-1, NT-proBNP levels in the severe group were significantly higher than the mild group and the moderate group, the difference was statistically significant (P<0.05). The hs-CRP, sVCAM-1, NT-proBNP of the moderate group were significantly higher than the mild group (P<0.05). There was a positive correlation between hs-CRP, sVCAM-1, NT-proBNP expression levels and the degree of the PIH. The expression of hs-CRP, sVCAM-1, NT-proBNP levels of the moderate and the severe group were significantly decreased (P<0.05). The number of placental villi and interstitial blood vessel in the moderate and severe PIH group were significantly less than the control group (P<0.05).@*CONCLUSIONS@#The increased levels of serum hs-CRP, sVCAM-1, NT-proBNP may be involved in the process of vascular endothelial cell injury of the PIH, and the hs-CRP, sVCAM-1, NT-proBNP can be used as the auxiliary index for diagnosis of PIH and determination of PIH severity.

ABSTRACT
BACKGROUND: Early escharectomy has been shown to improve the survival rates and the treatment outcomes of major burn patients. However, its exact mechanism, especially in terms of the human immune system, has not been fully elucidated. This observational study, which placed a focus on adhesion molecules, was conducted to assess changes of soluble intercelluar adhesion molecule-1 (sICAM-1), soluble vascular cell adhesion molecule-1 (sVCAM-1), and E-selectin in major burn patients undergoing early eschar excision. METHODS: Seventeen ASA physical status II or III adult major burn patients, admitted for plastic and reconstructive surgery for burn wound care, were initially recruited. When early escharectomy was scheduled, a series of blood samples were obtained four times at 72 and 24 hours preop and 24 and 72 hours postop, respectively. Changing levels of sICAM-1, sVCAM-1, and E-selectin were measured using quantitative sandwich immunoassay techniques. RESULTS: All patients suffered from major burns. Early escharectomy does not appear to have any significant impact on the levels of sICAM-1 and sVCAM-1. On the other hand, E-selectin levels showed a significant decrease after escharectomy. CONCLUSIONS: Major burn injury certainly induces a systemic inflammatory response. Adhesion molecules behave in such a way that escharectomy has a limited immunomodulatory effect in major burns. This is probably related to the timing and extent of surgery, and the complex nature of burn related inflammation.
