RESUMEN
Objective:To observe the rate of skin injury after spinal cord injury (SCI) in the rehabilitation department and analyze its risk factors.Methods:A total of 120 SCI patients were divided into an injury group of 33 and a control group of 87 without injury. The occurrence, type and location of any skin injuries incurred during hospitalization were recorded along with the subjects′ general condition, injury and functional status, complications, and the rehabilitation and nursing measures applied. Multivariate logistic regressions were evaluated to identify the risk factors for skin injury.Results:Among the 33 injuries, 27 were bruises (58.7%), 10 were stress injuries (21.7%), 5 were lacerations (10.9%) and 4 were burns (8.7%). Most injuries (65.2%) were to the limbs, followed by the buttocks and the sacrococcygeal tail (34.8%). All of the skin injuries required nursing intervention, with 47.8% lasting more than 7 days. There were significant differences between the two groups in terms of their average hospital stay, dysfunction, mode of admission, risk of pressure injury, nutrition and assisted urination. The regressions identified significant relationships between the occurrence of skin injury and length of hospital stay, risk of pressure injury and nutrition.Conclusions:The incidence of skin injury is high among hospitalized SCI patients. A long hospital stay, pressure injury and poor nutrition are independent risk factors for such patients. Such patients should receive skin management education.
RESUMEN
Objective:To explore the relationship between overweight and obesity, high blood pressure and left ventricular hypertrophy (LVH) in adolescents in Tangshan.Methods:Through cluster sampling, 1 023 adolescents aged 7-18 were selected from primary and secondary schools in Tangshan (January 2018 to January 2020). Questionnaire survey, blood pressure, weight, height measurement and ultrasound examination were performed. The incidence of LVH in 1 023 adolescents was statistically analyzed. 1 023 adolescents were divided into four groups according to whether they were overweight or obesity (overweight: weight for age Z score >2; obesity: height for age Z score >2) and whether blood pressure was high [high blood pressure: systolic blood pressure (SBP) or diastolic blood pressure (DBP)≥gender/age P 90 and <P 95; hypertension: SBP/DBP≥gender/age P 95]. The left ventricular mass index (LVMI) and the incidence of LVH were compared among different body weight and blood pressure. The relationship between overweight and obesity, high blood pressure and LVH was analyzed by multivariate logistic regression. Results:Among 1 023 adolescents, 98 were LVH and 925 were normal; the BMI, SBP, DBP, high blood pressure rate, and overweight and obesity rate in LVH group were significantly higher than normal group ( t=13.179, 3.239, 4.093; χ 2=12.998, 120.861, P<0.05). The LVMI level of each group increased with the increase of body weight and blood pressure ( P<0.05); the incidence of LVH in the overweight and obesity group with high blood pressure was significantly higher than that in the overweight and obesity group with normal blood pressure; the incidence of LVH was significantly higher in the overweight and obesity group with normal blood pressure was significantly higher than that in the high blood pressure and normal weight group ( P<0.05). Multivariate logistic regression analysis showed that compared with the normal blood pressure and weight groups, the risk of LVH increased significantly in the obesity and overweight group with high blood pressure and normal blood pressure [ OR (95% CI): 12.04(4.95-29.14), 14.32(5.66-36.26)], while the risk of LVH did not increase significantly in the high blood pressure and normal weight group [ OR (95% CI): 2.53(0.61-10.21)]. Conclusions:The adolescents in Tangshan area have a higher incidence of LVH. Simple high blood pressure will not increase the risk of LVH. However, overweight and obesity combined with high blood pressure can further increase the risk of LVH. We should actively prevent high blood pressure, control overweight and obesity, and reduce the risk of abnormal cardiac structure in adolescents.
RESUMEN
OBJECTIVE： To investigate the protective effect of total flavonoids from the leaves of Choerospondias axillaris （TFLC） on myocardial ischemia reperfusion injury （MIRI） model rats. METHODS： Male SD rats were randomly divided into sham operation group， model group， positive control group （verapamil， 0.02 g/kg）， TFLC low-dose and high-dose groups （0.1， 0.4 g/kg）， with 10 rats in each group. Administration groups were intragastrically given relevant medicine （2 mL/100 g）； sham operation group and model group were given constant volume of normal saline intragastrically， once a day， for consecutive 7 d. After last medication， MIRI model was induced by modified ligation method. The times and duration of ventricular tachycardia （VT） and ventricular fibrillation （VF） in rats were recorded with biological function experiment system during reperfusion period.The activity of CK and contents of TNF-α， IL-6， NF-κB and NO in serum were determined by ELISA double antibody clip art assay. The morphological characteristics of myocardial tissue was observed by HE staining. The myocardial infarction scope （i.e. the ratio of myocardial tissue mass to ventricular mass） was measured by TTC method. RESULTS： Compared with sham operation group， the times and duration of VT and VF were increased or prolonged significantly in model group； CK activity， serum contents of TNF-α， IL-6 and NF-κB were enhanced or increased significantly， while NO content was decreased significantly （P＜0.05 or P＜0.01）. Obvious myocardial infarction focus， serious cell structure damage， disorderly muscle fibers arrangement， cell nucleus pyknosis and accompanied inflammatory cell infiltration were all observed in cardiac tissue； the mass of infarcted myocardial tissue and ventricular as well as the scope of myocardial infarction increased significantly （P＜0.01）. Compared with model group， the times and duration of VT and VF were decreased or shortened significantly in administration groups； CK activity， serum contents of TNF-α， IL-6， NF-κB were decreased significantly， while NO content was increased significantly （P＜0.05 or P＜0.01）. The above symptoms of myocardial injury were improved；the mass of infarcted myocardial tissue and ventricular as well as the scope of myocardial infarction was significantly reduced （P＜0.05 or P＜0.01）. CONCLUSIONS： TFLC can relieve MIRI-induced ischemic arrhythmia and myocardial damage， reduce the release of inflammatory factors， promote the recovery of myocardial and endothelial cell function， reduce the scope of myocardial infarction and has a certain protective effect.

RESUMEN
Toutongling Capsule is a Chinese herbal preparation developing from an ancient formula processed by modern technology. Previous clinical studies have shown that Toutongling Capsule exerts a good effect on vascular headache, tonic headache and traumatic headache. To further explore its pharmacological mechanism, the effect of Toutongling Capsule on cerebral vessels and blood viscosity in experimental dogs was observed. The results showed that Toutongling Capsule can decrease cerebral vascular resistance obviously and increase cerebral blood flow, with a good dose-effect relationship. As compared with Yangjiao Granule, Toutongling Capsule possesses a similar effect on blood viscosity but stronger effect on dilatation of cerebral vessels and increase of cerebral blood flow. Both Toutongling Capsule and Yangjiao Granule have no effect on blood pressure and ECG.
