RESUMEN
OBJECTIVE@#To observe the effects of electro-scalp acupuncture (ESA) on the expression of microglial markers CD206 and CD32, as well as interleukin (IL)-6, IL-1β, and IL-10 in the ischemic cortex of rats with ischemic stroke, and to explore the mechanisms of ESA on alleviating inflammatory damage of ischemic stroke.@*METHODS@#Sixty 7-week-old male SD rats were randomly selected, with 15 rats assigned to a sham surgery group. The remaining rats were treated with suture method to establish rat model of middle cerebral artery occlusion (MCAO). The rats with successful model were randomly divided into a model group, a VitD3 group, and an ESA group, with 15 rats in each group. In the ESA group, ESA was performed bilaterally at the "top-temporal anterior oblique line" with disperse-dense wave, a frequency of 2 Hz/100 Hz, and an intensity of 1 mA. Each session lasted for 30 min, once daily, for a total of 7 days. The VitD3 group were treated with intragastric administration of 1,25-dihydroxyvitamin D3 (1,25-VitD3) solution (3 ng/100 g), once daily for 7 days. The neurological deficit scores and neurobehavioral scores were assessed before and after the intervention. After the intervention, the brain infarct volume was evaluated using 2,3,5-triphenyltetrazolium chloride (TTC) staining. Immunofluorescence double staining was performed to detect the protein expression of CD32 and CD206 in the ischemic cortex. Western blot analysis was conducted to measure the protein expression of IL-6, IL-1β, and IL-10 in the ischemic cortex.@*RESULTS@#Compared with the sham surgery group, the model group showed increased neurological deficit scores and neurobehavioral scores (P<0.01), increased brain infarct volume (P<0.01), increased protein expression of CD32, IL-6, and IL-1β in the ischemic cortex (P<0.01), and decreased protein expression of CD206 and IL-10 in the ischemic cortex (P<0.01). Compared with the model group, both the ESA group and the VitD3 group showed decreased neurological deficit scores and neurobehavioral scores (P<0.01), reduced brain infarct volume (P<0.01), decreased protein expression of CD32, IL-6, and IL-1β in the ischemic cortex (P<0.01), and increased protein expression of CD206 and IL-10 in the ischemic cortex (P<0.01). Compared with the VitD3 group, the ESA group had lower neurological deficit score (P<0.05), larger brain infarct volume (P< 0.05), and lower protein expression of CD32, CD206, IL-1β, and IL-10 in the ischemic cortex (P<0.01, P<0.05).@*CONCLUSION@#ESA could improve neurological function in MCAO rats, and its mechanism may be related to promoting microglial M1-to-M2 polarization and alleviating inflammatory damage.

RESUMEN
Aspergillus niger is an important industrial strain which has been widely used for production of enzymes and organic acids. Genome modification of A. niger is required to further improve its potential for industrial production. CRISPR/Cas9 is a widely used genome editing technique for A. niger, but its application in industrial strains modification is hampered by the need for integration of a selection marker into the genome or low gene editing efficiency. Here we report a highly efficient marker-free genome editing method for A. niger based on CRISPR/Cas9 technique. Firstly, we constructed a co-expression plasmid of sgRNA and Cas9 with a replication initiation region fragment AMA1 (autonomously maintained in Aspergillus) by using 5S rRNA promoter which improved sgRNA expression. Meanwhile, a strain deficient in non-homologous end-joining (NHEJ) was developed by knocking out the kusA gene. Finally, we took advantage of the instability of plasmid containing AMA1 fragment to cure the co-expression plasmid containing sgRNA and Cas9 through passaging on non-selective plate. With this method, the efficiency of gene editing reached 100% when using maker-free donor DNA with a short homologous arm of 20 bp. This method may facilitate investigation of gene functions and construction of cell factories for A. niger.

As an increasingly mature analytical technique, surface-enhanced Raman spectroscopy has the ability to identify, detect, and even quantitatively measure many single substances in nature. However, in the actual sample analysis, the tested samples were often a mixed system of various substances, and it was impossible to accurately characterize the components of the mixed system only by relying on SERS technology. Therefore, SERS combined with other techniques to accurately determine the measured substances has become an inevitable trend. Through the combination, the deficiency of SERS in detection and characterization was improved, and the purpose of efficient, sensitive and accurate determination of substances to be measured was achieved.

<p><b>OBJECTIVE</b>To observe the protective effect of Kang Naoxueshuan Tablet (KNT) on ischemic brain injury in rats, and explore its possible mechanism.</p><p><b>METHODS</b>Rats were administrated with KNT twice per day for successive 14 days. Rat model of acute focal cerebral ischemia was established by middle cerebral artery occlusion (MCAO) with a nylon suture inserted through the right internal carotid artery to occlude the beginning of middle cerebral artery. After 24 hrs MCAO, the neurological deficit and the volume of cerebral infarct were observed, and the effect of KNT on the thrombosis of rats in vitro, platelet aggregation and blood viscosity were also determined.</p><p><b>RESULTS</b>KNT could alleviate volume of cerebral infarct caused by focal cerebral ischemia in a dose-dependent manner and improve neurological symptoms. The volume of cerebral infarct was 11. 18 +/- 3. 35% , 14. 60 +/- 7.00% and 15. 37 +/- 7. 21% in the high, middle and low-dose groups, respectively, and they were decreased 59. 36% , 46. 93% and 44. 13% than that in the model group 27. 51 +/- 4. 71% (P <0. 01 ). The wet and dry weigh of thrombosis in vitro of the three different dose groups were significantly decreased, and they were significantly different than that of the model group (P <0. 05, P <0. 01). KNT could significantly inhibit platelet aggregation induced by ADP and decrease blood viscosity, but it had no effect on plasma viscosity and hematocrit.</p><p><b>CONCLUSION</b>KNT has significant protective effect on ischemia, the mechanism is relateed to the improvement of blood viscosity and inhibiti on of platelet aggregation. But the exact mechanisms need to be probed into deeply.</p>
