我国人体首次发现圆圃棘口吸虫病例及虫体形态观察

1988年7月6日,我们在一患者便内发现似姜片虫卵的大型虫卵。临床表现为头昏无力、食欲不振,上腹痛和贫血。因病人20天前有吞食活泥鳅史,故疑其为棘口吸虫病。服药后获虫体70条,经形态学研究,鉴定为圆圃棘口吸虫(Echinostoma hortense Asada,1926)。

Site-specific homologous recombination mutagenesis in group B streptococci

We describe the use of suicide vectors to generate site-specific mutations in group B streptococcus. This is accomplished by cloning gene-specific sequences into a temperature sensitive plasmid and selecting for clones which have undergone homologous recombination. The recombinan clones can be easily isolated by selecting for clones which have retained the antibiotic resistance markers that are present on the vector or cloned into the gene-specific sequences. To confirm the fidelity of the recombination events, PCR analysis is performed on chromosomal DNA isolated from the recombinant clones. Using this strategy, we have generated site- specific insertions in several capsule genes and have found that these insertions occurred as expected and that the mutations result in loss of capsule expression. In this report, we specifically detail the construction of cpsB mutants by single and double cross-over recombination and demonstrate that the resulting strains are acapsular.

Neuroprotective effects of Longxue Tongluo Capsule on ischemic stroke rats revealed by LC-MS/MS-based metabolomics approach

Objective: The present study aimed to evaluate the therapeutic effect and explore the underlying mechanisms of Longxue Tongluo Capsule (LTC) on ischemic stroke rats. Methods: Twenty-six rats were randomly divided into four groups, including sham group, sham + LTC group, MCAO group, and MCAO + LTC group. Ischemic stroke rats were simulated by middle cerebral artery occlusion (MCAO), and LTC treatment group were orally administrated with 300 mg/kg of LTC once daily for seven consecutive days. LTC therapy was validated in terms of neurobehavioral abnormality evaluation, cerebral infarct area, and histological assessments. The plasma metabolome comparisons amongst different groups were conducted by UHPLC-Q Exactive MS in combination with subsequent multivariate statistical analysis, aiming to finding the molecules in respond to the surgery or LTC treatment. Results: Intragastric administration of LTC significantly decreased not only the neurobehavioral abnormality scores but also the cerebral infarct area of MCAO rats. The interstitial edema, atrophy, and pyknosis of glial and neuronal cells occurred in the infarcted area, core area, and marginal area of cerebral cortex were improved after LTC treatment. A total of 13 potential biomarkers were observed, and Youden index of 11 biomarkers such as LysoPC, SM, and PE were more than 0.7, which were involved in neuroprotective process. The correlation and pathway analysis showed that LTC was beneficial to ischemic stroke rats via regulating glycerophospholipid and sphingolipid metabolism, together with nicotinate and nicotinamide metabolism. Heatmap and ternary analysis indicated the synergistic effect of carbohydrates and lipids may be induced by flavonoid intake from LTC. Conclusion: The present study could provide evidence that metabolomics, as systematic approach, revealed its capacity to evaluate the holistic efficacy of TCM, and investigate the molecular mechanism underlying the clinical treatment of LTC on ischemic stroke.
