AIM: To investigate the effect of gastrodin on the expression of brain-derived neurotrophic factor (BDNF) and interleukin-6 (IL-6) in the striatum of cerebral ischemia rats, and to explore the potential mechanism of gastrodin in treating cerebral ischemia. METHODS: The rats were randomly divided into four groups: normal, sham, model, and gastrodin groups, each consisting of 10 rats. After successful modeling using middle cerebral artery occlusion (MCAO), the gastrodin group received intraperitoneal injection of gastrodin injection at a dose of 10 mg/kg once a day for 14 consecutive days. Pathological changes in striatal neurons were observed using Nissl staining. Immunohistochemistry was utilized to detect positive expression of BDNF and IL-6 proteins in the striatum. Additionally, immunoblot analysis was performed to determine the expression levels of BDNF and IL-6 proteins in the striatum. RESULTS: Nissl staining revealed clear and intact structures of striatal neurons in the normal and sham groups, with tightly arranged cells. In the model group, the number of cells was significantly reduced compared to the sham group (P<0.01), and there was a noticeable cytosolic atrophy and loose cell arrangement. The gastrodin group showed a significant increase in the number of Nissl-positive neurons compared to the model group (P<0.01), and there was also a significant improvement in cell morphology. The results of immunohistochemistry and immunoblot were consistent, and there was no statistically significant difference in BDNF and IL-6 protein expression between the normal group and the sham group (P>0.05). Compared to the sham group, the model group showed a decrease in the protein expression level of BDNF in the striatum on the ischemic side (P<0.01) and an increase in the protein expression level of IL-6 (P<0.05, P<0.01). In contrast, the gastrodin group showed an increase in the protein expression level of BDNF in the striatum on the ischemic side (P<0.05, P<0.01) and a decrease in the protein expression level of IL-6 (P< 0.05, P<0.01) compared to the model group. CONCLUSION: Gastrodin has a significant protective effect on striatal injury caused by cerebral ischemia, and its mechanism may be related to the up-regulation of the anti-inflammatory factor BDNF and the down-regulation of the pro-inflammatory factor IL-6.

To establish a simple,convenient,sensitive,and specific method for rapid detection of Zi-ka virus(ZIKV),the whole genome sequences of ZIKV isolated from different times and regions were analyzed.The specific primers and probes were designed based on the screened target se-quences located in the conserved region of the ZIKV NS5 gene.By combining RT-LAMP isother-mal amplification technology and immunochromatography technology,a reverse transcription loop mediated isothermal amplification nucleic acid and flow visualization strip(RT-LAMP-VF)detec-tion method for ZIKV was established.The results showed that the method had good specificity and sensitivity.When the ratio of inner,outer,and ring primers(FIP∶LF∶F3)was 4∶2∶1,the detection method can specifically detect 102 copies/pL RNA transcripts or 2.15 pfu ZIKV at 61 ℃for 45 minutes,with no cross reaction with other flaviviruses such as Japanese encephalitis virus and classical swine fever virus.Other RNAs in blood tissue samples did not affect the sensitivity and specificity of RT-LAMP-VF,indicating that the method can be applied to clinical practice.The ZIKV RT-LAMP-VF detection method established in this study is easy to perform and does not require special instruments and equipment.It is particularly suitable for the rapid detection of ZIKV in grassroots units,providing technical support and material support for the establishment of on-site rapid detection and early warning and prediction systems for ZIKV disease.
