RESUMO
Objective: This study aimed to explore the risk factors and dietary status of middle-aged and elderly people at high risk of stroke in urban and rural areas of Xiangtan City, with a view to providing a basis for formulating stroke prevention and control strategies in urban and rural areas of Xiangtan City. Methods: Using the cluster sampling method, a total of 8,453 permanent residents aged ≥40 years old were selected from Yuetang Street, Yuetang District, and Jiangshe Town, Yuhu District, Xiangtan City in 2020 and 2021 for face-to-face questionnaire surveys to collect their demographic information, daily life Method, family history, height, weight, waist circumference, blood pressure, blood sugar, blood lipids, glycosylated hemoglobin, homocysteine and other indicators, and analyze them. Results: A total of 8453 permanent residents were screened in this study, and a total of 1804 stroke high-risk patients (including stroke and TIA, 21.34%) were screened out, including 973 urban residents (23.53%), and 831 rural residents (19.25%), and the distinction had statistical significance (P < .05); 263 stroke sufferers were screened out, and the prevalence ratio was 3.11%. The exposure rates of risk factors for high-risk groups in urban and rural areas of Xiangtan City from high to low are hypertension, dyslipidemia, smoking, family history of stroke, diabetes, obesity, lack of exercise and atrial fibrillation or heart valve disease. The high-risk groups for urban strokes The proportions of lack of exercise (23.54%) and obesity (38.44%) were significantly higher than the proportions of lack of exercise (17.09%) and obesity (22.64%) in rural areas. The high-risk groups in rural areas had hypertension (87.73%) and a history of TIA (2.89%). The proportion of patients with hypertension (82.43%) and TIA history (1.34%) was significantly higher than those in urban areas, and the differences were statistically significant (P < .05). The proportion of rural residents who eat a salty diet (17.93%) and eat fruits ≤2 days/week (93.98%) is significantly higher than that of urban residents who eat a salty diet (14.49%) and eat fruits ≤2 days/week (59.61%). There are differences. Statistically significant (P < .05), the proportion of urban residents who consume vegetables ≤2 days/week (11.91%) is significantly lower than the proportion of urban residents who consume vegetables ≤2 days/week (28.98%) (P < .01). Conclusion: The high-risk factors for stroke in Xiangtan City are mainly hypertension, dyslipidemia, smoking history, family history of stroke, and diabetes. Tailored public health measures should be taken by residents to address the different risk status and dietary habits of urban and rural populations. Especially dietary intervention for rural residents.
RESUMO
The spinal cord injury (SCI) is one of the major reasons causing the motor dysfunctions of the patients. At present, few therapeutic strategies can effectively improve the symptom of SCI. Levetiracetam has been confirmed to alleviate the injury of nerve cells, while its functions in SCI remains unclear. In this study, C57BL/6J mice were used to establish SCI models to observe the effect of levetiracetam on SCI. The mice were fed with 180 mg/kg levetiracetam when suffering from SCI, and Basso mouse score (BMS) and CatWalk-assisted gait analysis were used to observe the motor functions of the mice. Nissl staining and TUNEL staining were used to observe the injury of nerve cells. The abundance of inflammatory factors was measured by ELISA. The permeability of blood-spinal cord barrier (BSCB) in mice was detected with macrophage infiltration analysis. Moreover, the abundance of perforin in the tissues was detected by western blot. The results showed that the SCI mice treated with levetiracetam exhibited lighter motor dysfunction compared with the mice treated with saline. Levetiracetam can effectively reduce the inflammatory reactions and alleviate apoptosis of the nerve cells. Moreover, levetiracetam remarkably decreased the BSCB permeability of SCI mice. Besides, it was also found that levetiracetam can significantly inhibit the expression of perforin. In conclusion, this study suggests that levetiracetam can attenuate the injury of BSCB to block the progression of SCI via suppressing the expression of perforin.
