GO analysis showed that in terms of biological processes, the genes related to inflammatory response and neutrophil chemotaxis were the most. In terms of molecular function, chemokine activity-related genes are the most. KEGG signaling pathway analysis showed that the most differentially expressed genes were located in the TNF signaling pathway. <b>Conclusion:</b> H-type hypertension with acute cerebral infarction has a variety of functional proteins and signaling pathways changes, suggesting that inflammatory response in H-type hypertension with acute cerebral infarction recovery period may still play a role in the prognosis and reactivation of the disease. 展开更多

A new method combining QuEChERS (quick, easy, cheap, effective, rugged and safe) and DLLME (dispersive liquid–liquid microextraction) for the simultaneous determination of residues of ten sulfonylurea herbicide in water using UPLC-MS/MS was developed and validated. Analytes were extracted and purified with QuEChERS and concentrated in chlorobenzene by applying the DLLME procedure. Several extraction parameters were tested, such as volume, extractive solvent by the QuEChERS method and subsequently used for DLLME, selection of extractive solvent and its volume, was tested. The developed method was validated on the basis of international guidelines. Mean recoveries ranged from 81.2 to 104.9%. Repeatability and reproducibility were lower than 10%. Limits of detection (LODs) and quantification (LOQs) were below 0.074 μg/L and 0.244 μg/L, respectively. Decision limit (CCα) and detection capability (CCβ) were calculated and CCβ ranged from 0.101 μg/L (pyrazosulfuron-ethyl) to 0.260 μg/L (nicosulfuron). Finally, when the method was applied to real samples, traces of three compounds were found in 42 samples and only thifensulfuon-methyl was detected above the LOQ in three samples at 0.17-0.20 μg/L. 展开更多

The polymorphisms of rs6265 locus of 5-HTTLPR and BDNF genes were detected by PCR (polymerase chain reaction) and page (polycylamide gel electrophoresis), and the correlation with PTSD was analyzed. Logistic regression analysis was used to analyze the influencing factors of PTSD. <strong>Results:</strong> The ETI score, total PTSD score and TMT time of Li PTSD patients were significantly higher than those of Han PTSD patients (P < 0.01). The comprehension, picture filling, picture arrangement, operation IQ and total IQ of WAIS-RC were significantly lower than those of Han PTSD patients (P < 0.01);The numbers of errors, TMT and Toh in WCST were significantly lower than those in Han PTSD patients (P < 0.01). There was no significant difference in the distribution of 5-HTTLPR genotype and allele between Li PTSD patients and control group (P > 0.05). SS genotype of 5-HTTLPR and (GA + AA) genotype of rs6265 locus may increase the risk of PTSD in Hainan Han population. AA and GA + AA genotypes at rs6265 locus may increase the risk of PTSD in Li population (P < 0.05). Among Li PTSD patients, the ETI score, PTSD total score, TMT time, Toh planning time and execution time of AA genotype at rs6265 locus were significantly higher than those of GG genotype;the total scores of comprehension and operation IQ, and Toh in WAIS-RC were significantly lower than those in GG genotype (P < 0.05).

The peripheral venous whole blood of the subjects was drawn, genomic DNA was extracted, modified with bisulfite, and directly sequenced to quantitatively detect the methylation status of the CpG island in the promoter region of brain-derived neurotrophic factor (BDNF). <b>Results:</b> The results showed that the methylation levels of CPGl, CPG2, CPG3, CPG4, CPG5, CPG6, CPG7, CPG9, CPGl2, CPGl3, CPGl4, CPGl5, CPGl6, CPGl7, and CPGl8 in THE BDNF promoter were significantly different between the HAN PTSD group and the Li PTSD group (<i>P</i> < 0.001). <b>Conclusion:</b> It is suggested that CPG methylation in the promoter region of BDNF gene is closely related to patients with PTSD. There is a statistical difference in the level of CpG methylation in the promoter region of BDNF gene in PTSD between Li and Han ethnic groups in Hainan Province. CpG methylation in the promoter region of BDNF gene may be used as a biomarker for the diagnosis of PTSD. 展开更多

目的:探讨磁共振动态增强扫描(DCE-MR)评价高血压偏头痛微循环改变及对中医证候分型的价值。方法:选取20例高血压偏头痛患者(肝阳上亢证型10例、非肝阳上亢型10例)与10名健康对照者,行DCE-MR检查,使用Omni-Kinetic软件分析每组颅底肌肉... 目的:探讨磁共振动态增强扫描(DCE-MR)评价高血压偏头痛微循环改变及对中医证候分型的价值。方法:选取20例高血压偏头痛患者(肝阳上亢证型10例、非肝阳上亢型10例)与10名健康对照者,行DCE-MR检查,使用Omni-Kinetic软件分析每组颅底肌肉容积转移常数Ktrans,血管外细胞外容积比Ve,速率常数Kep,比较三组间差异。结果:肝阳上亢证偏头痛组、非肝阳上亢证偏头痛组与健康组Ktrans、Kep及Ve均存在差异(P <0.05);但肝阳上亢证组与非肝阳上亢证组Ktrans、Kep及Ve比较均无统计学意义,即增强效果无差别(P> 0.05)。结论:DCE-MR能客观评价高血压偏头痛患者微循环异常,但并不能完全区分肝阳上亢中医证候分型。 展开更多

牛呼吸道疾病综合征(BRDC)是一种急性呼吸道疾病,其主要细菌性病原有多杀性巴氏杆菌、溶血性曼氏杆菌、化脓隐秘杆菌和昏睡嗜血杆菌,常见于断奶、运输等应激后牛群。该病呈世界性分布,可经呼吸道感染,严重影响肉牛及泌乳牛的品质,给养... 牛呼吸道疾病综合征(BRDC)是一种急性呼吸道疾病,其主要细菌性病原有多杀性巴氏杆菌、溶血性曼氏杆菌、化脓隐秘杆菌和昏睡嗜血杆菌,常见于断奶、运输等应激后牛群。该病呈世界性分布,可经呼吸道感染,严重影响肉牛及泌乳牛的品质,给养牛业造成巨大的经济损失。国内关于BRDC的研究仍比较匮乏,且尚无可预防BRDC细菌性病原的疫苗,为更好地防控BRDC,现就国内外BRDC细菌性病原的致病机理和防控研究进展做一综述。 展开更多
