RESUMO

Hemigyrus was established by Brunner von Wattenwyl in 1893. In this study, we collected samples from Chongqing, Guangxi, Hainan, Sichuan, Tibet and Yunnan of China, and reconstructed phylogenetic tree based on COI gene. The results supported the classification of dividing this genus into two subgenera: Tomomima and Hemigyrus. With larger size and evidently branched phylogenetic position, a new subspecies H. (T.) spinosus robustus subsp. nov. Xie, Wang He is described here. H. (H.) acutifolius is firstly reported from China. Males of H. (H.) amplus and H. (H.) acutifolius, females of H. (H.) minor are described for the first time. All materials were deposited in Biological History Museum of East China Normal University (ECNU) and the Shanghai Entomological Museum, Chinese Academy of Sciences (SEM).

RESUMO

We provide a key to mute Trigonidiinae species from China, and provide morphological features of some nondescript species in brown color. We established a new genus, Zilingxi He gen. nov. with two new species Z. danmai He sp. nov. and Z. dian He sp. nov. from China. The new genus possesses a black line above clypeus; pseudepiphallic paramere of male genitalia possessing 23 branches; ovipositor shorter than other genera. Two new species are very similar in morphology, but different in the color pattern in frontal rostrum, and the shape of male genitalia. The type specimens are deposited in Museum of Biology, East China Normal University (ECNU).

RESUMO

Paeoniflorin (PF) has numerous benefits, including anti-inflammatory and anti-apoptosis effects. However, it is not clear if it has neuroprotective effects against cognitive impairment (CI) in Parkinson's disease (PD). Through network pharmacology, we identified probable targets as well as signal pathways through which PF might affect CI in PD. Then, we experimentally validated our findings. The core genes of the protein-protein interactions (PPI) network include MAPK8 (JNK), TP53, CASP3 (caspase-3), postsynaptic density protein-95 (PSD-95) and synaptophysin (SYN). Pathway enrichment analysis revealed that genes involved in apoptosis and mitogen-activated protein kinase (MAPK) signaling were significantly enriched. Because JNK is a key mediator of p53-induced apoptosis, we wondered if JNK/p53 pathway influences the effects of PF against apoptosis in mouse model of PD. Molecular docking analysis showed that PF had good affinity for JNK/p53. The results of the experiments indicated that PF ameliorated behavioral impairments and upregulated the expression of the dopamine (DA) neurons, suppressed cell apoptosis in substantia nigra pars compacta (SNpc) of PD. Additionally, PF improved 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-induced neuronal injury by inhibiting apoptosis in hippocampal neurons of the CA1 and CA3, and upregulating PSD-95 as well as SYN protein levels. Similar protective effects were observed upon JNK/p53 pathway inhibition using SP600125. Overall, PF improved CI in PD by inhibiting JNK/p53 pathway.

RESUMO

Six species of geckos in the genus Goniurosaurus have been recorded from Guangxi, China. Here we describe a new species, Goniurosaurus chengzheng sp. nov. The new species is similar to allied species from Guangxi, but unique in a combination of the following characters: (1) four body bands with three between limb insertions; (2) precloacal pores 20; (3) body color reddish- brown; (4) snout to eye distance: eye to ear distance 1. We used the mitochondrial genes 16S and cytb to confirm the distinctiveness of the species and place it within a molecular phylogeny of Goniurosaurus. The type specimens are deposited in the Museum of Biology, East China Normal University (ECNU).

RESUMO

We studied the relationship of the genera Loxoblemmus Saussure, 1877 and Asonicogryllus He, 2019 by reconstructing the phylogenetic tree based on 2 mitochondrial genes and 2 ribosomal genes. The result shows that Loxoblemmus is paraphyletic. Thus, we place Asonicogryllus as a subgenus of Loxoblemmus. Meanwhile, we report a new species of Asonicogryllus, L. (A.) bronzus He sp. nov. The new species is similar to L. (A.) kwanghua, but it has well developed forewings and hindwings. The type specimens are deposited in the Museum of Biology, East China Normal University (ECNU).

RESUMO

Compound Dihuang Granule (CDG) is widely used in traditional Chinese medicine (TCM) for the treatment of Parkinson's disease (PD). It has been shown to alleviate PD symptoms. However, the molecular mechanisms of its action have not been established. To establish the molecular mechanisms of CDG against PD, we used TCM network pharmacology methods to predict its molecular targets and signaling pathways, followed by experimental validation. The Core Protein protein interaction (PPI) network of the 150 intersections between CDG and PD-related genes, comprising 23 proteins, including CASP3 (caspase-3), MAPK8 (JNK), FOS (c-Fos), and JUN (c-Jun). KEGG and GO analyses revealed that apoptotic regulation and MAPK signaling pathways were significantly enriched. Since c-Jun and c-Fos are AP-1 subunits, an important downstream JNK effector, we investigated if the JNK/AP-1 pathway influences CDG against apoptosis through the nigrostriatal pathways in PD rat models. Molecular docking analysis found that the top three bioactive compounds exhibiting the highest Degree Centrality following online database and LC-MS analysis had high affinities for JNK. Experimental validation analysis showed that CDG decreased the number of rotating laps and suppressed the levels of phosphorylated c-Jun, c-Fos, and JNK, as well as the number of TUNEL positive cells and the cleaved caspase-3 level in the nigrostriatal pathway. Furthermore, CDG treatment elevated the number of TH neurons, TH expression level, and Bcl-2/Bax protein ratio in a 6-OHDA-induced PD rat. These findings are in tandem with those obtained using SP600125, a specific JNK inhibitor. In conclusion, CDG suppresses the apoptosis of the nigrostriatal pathway and relieves PD symptoms by suppressing the JNK/AP-1 signaling pathway.

RESUMO

There are 29 species or subspecies in genus Hexacentrus occurring in Asia, Africa and Australia. Because of its similar appearance, it is not easy to distinguish them by traditional methods. In this study, we collected samples and sequenced COI genes from wide range. By reconstructing the gene tree, we found one new species, H. formosanus Chen et He sp. nov., from Taiwan. The new species is similar to H. expansus or H. inflatissimus, but differs from the former in male Cu2 vein of left tegmina curved and slender, and spectrum of male left tegmina slender and subsquare; differs from the later by body size smaller and female tegmina narrow and short. The type specimens are deposited in National Museum of Natural Science, Taichung, Taiwan (NMNS). H. japonicus hareyamai is treated as species level, H. hareyamai stat. nov.

RESUMO

To date, only one species of whip spider has been recorded in China. Here, we describe a new species, Weygoldtia hainanensis sp. nov., from Hainan, China. The new species is morphologically similar to W. davidovi (Fage, 1946) and W. consonensis Miranda et al. 2021, but can be distinguished with a combination of the following characters: 26 segments in tibia I, 6-7 teeth on chelicerae, distitibia IV trichobothria sc and sf series each with 10-11 trichobothria. To validate our morphological inferences and support the erection of W. hainanensis sp. nov. as a new species, we sequenced the COI gene region for two individuals and performed molecular phylogenetic analyses. The inferred phylogenetic trees placed the new species within Weygoldtia and highlighted the evolutionary distinction between W. hainanensis sp. nov. and currently described whip spiders. The type specimens are deposited in the Museum of Biology, East China Normal University (ECNU).
