Methods: In this study, 90 patients with acute cerebral infarction hospitalized in Zhuji People’s Hospital from December 2023 to December 2024 were selected and divided into two groups of 45 patients in each group. The control group used standard medical treatment, and the treatment group compared the changes of serum inflammatory factors IL-CRP, TNF-α, and Hcy with Huoxue Tongmai capsule for 7 days, 14 days and 30 days, and discussed the changes of the modified Rankin scale score (mRS) and National Institutes of Health Stroke Scale (NIHSS) score. Results: At 7 days, 14 days, and 30 days of treatment, the NIHSS score, mRS score, hs-CRP, IL-6, TNF-α, and Hcy levels were statistically significant (P α, and Hcy levels in the treatment group were significantly lower than those in the control group (P Conclusion: Patients with acute cerebral infarction received Huoxue Tongmai capsule combined with edaravone right camphor, which can reduce the inflammatory reaction, improve the nerve function and improve the prognosis.展开更多

Recently, with the free open of the attractions around the West Lake and the implementation of the comprehensive pro- ject for protecting the West Lake, a part of ancient fragrant camphor trees are fac- ing problems such as altered living conditons. Some of them are showing a decline in growth vigor or even close to death, which will produce extremely negative influ- ences on the maintaining and sustainable development of the West Lake Scenic Area if without any timely measures for the rescue and rejuvenation of the trees. Therefore, strengthening the protection and management of ancient fragrant camphor trees at the West Lake Scenic Area and carrying out researches on the procedure for diagnosing the reasons for the growth recession of the ancient fragrant camphor trees at the West Lake Scenic Area are of great significance for the future protec- tion and rejuvenation of the ancient trees around the West Lake. The factors influ- encing the growth of ancient trees and indexes for judging the growth condition were listed and the reasons for the growth recession were systematically summa- rized in this paper. In addition, measures for the rejuvenation of the ancient fragrant camphor trees were also simply discussed.展开更多
