ABSTRACT
Despite considerable research efforts in recent years, the deeper phylogenetic relationships among skipper butterflies (Hesperiidae) remain unresolved. This is primarily because of limited sampling, especially within Asian and African lineages. In this study, we consolidated previous data and extensively sampled Asian and African taxa to elucidate the phylogenetic relationships within Hesperiidae. The molecular dataset comprised sequences from two mitochondrial and two nuclear gene regions from 563 species that represented 353 genera. Our analyses revealed seven subfamilies within Hesperiidae: Coeliadinae, Euschemoninae, Eudaminae, Pyrginae, Heteropterinae, Trapezitinae, and Hesperiinae. The systematics of most tribes and genera aligned with those of prior studies. However, notable differences were observed in several tribes and genera. Overall, the position of taxa assigned to incertae sedis in Hesperiinae is largely clarified in this study. Our results strongly support the monophyly of the tribe Tagiadini (Pyrginae), and the systematics of some genera are clarified with comprehensive discussion. We recognize 15 tribes within the subfamily Hesperiinae. Of these, nine tribes are discussed in detail: Aeromachini, Astictopterini, Erionotini, Unkanini (new status), Ancistroidini, Ismini (confirmed status), Plastingini (new status), Gretnini (confirmed status), and Eetionini (confirmed status). We propose four subtribes within Astictopterini: Hypoleucina subtrib.n., Aclerosina, Cupithina, and Astictopterina. Furthermore, we describe a new genus (Hyarotoidesgen.n.) and reinstate two genera (Zeareinst.stat. and Separeinst.stat.) as valid. Additionally, we propose several new combinations: Zea mythecacomb.n.,Sepa bononiacomb.n. & reinst.stat., and Sepa umbrosacomb.n. This study, with extensive sampling of Asian and African taxa, greatly enhances the understanding of the knowledge of the skipper tree of life.

The range of the butterfly genus Pseudocoladenia includes several biodiversity hotspots, such as the Himalayas, mountains of southwestern China, and Sundaland. However, the taxonomic status of some of its species/subspecies remain controversial, and no previous phylogenetic or biogeographic analyses have been conducted. Herein, we determined the systematic relationships and biogeographic history of this genus by reconstructing its phylogeny based on six genes and 69 specimens as representatives of all known species/subspecies. Two species delimitation methods (Bayes Poisson Tree Processes and Bayesian Phylogenetics and Phylogeography) were also employed to assess the status of each taxon. Based on these results and morphological evidence, we identified 12 species and three subspecies in the genus and subsequently classified these into three species groups: P. fatih, P. dea, and P. dan. Five taxa, P. sadakoe (Sonan and Mitono, 1936) stat. nov., P. celebica (Fruhstorfer, 1909) stat. nov., P. fulvescens (Elwes and Edwarda, 1897) stat. nov., P. eacus (Latreille, 1823) stat. nov., and P. fabia (Evans, 1949) stat. nov. were all recognized as independent species. Additionally, two taxa, P. eacus sumatrana (Fruhstorfer, 1909) comb. nov. and P. eacus dhyana (Fruhstorfer, 1909) comb. nov., were placed under P. eacus (Latreille, 1823) stat. nov. as subspecies. Another new species distributed in N. Yunnan, Pseudocoladenia yunnana Fan, Cao & Hou sp. nov., was discovered and described. Divergence time and ancestral range estimation indicated that the most recent common ancestor of Pseudocoladenia was distributed in the Himalayas-Hengduan Mountain region and Indochina and diverged approximately 14.00 Ma. Continuous and episodic dispersal, vicariance, and extinction were used to determine the current geographic distribution of the genus. The P. fatih group had a prominently disjunct distribution between the Himalaya-Hengduan Mountain and Taiwan. Meanwhile, the P. dan group was first derived in Indochina and subsequently dispersed into the southeastern Asian archipelagoes. This study provides a reference for the evolutionary route of transoceanic distributed species in Asia and elaborates on the causes of biodiversity.

MicroRNAs (miRNAs) are critical regulatory factors in myocardial ischemia/reperfusion (I/R) injury. The miRNA miR-30c-5p has been reported as a key mediator in several myocardial abnormalities. However, the precise roles and mechanisms of miR-30c-5p in myocardial I/R injury remain not well-studied. This project aimed to explore the potential function of this miRNA in mediating myocardial I/R injury. Significant induction of miR-30c-5p was observed in myocardial tissue of rats with myocardial I/R injury in vivo and cardiomyocytes with hypoxia/reoxygenation (H/R) injury in vitro. Functional studies elucidated that forced expression of miR-30c-5p in rats effectively reduced infarct area, cardiac apoptosis, oxidative stress and inflammation induced by myocardial I/R injury. Moreover, in vitro cardiomyocytes with forced expression of miR-30c-5p were also protected from H/R-induced apoptosis, oxidative stress and inflammation. Importantly, BTB domain and CNC homology 1 (Bach1) was identified as a new target of miR-30c-5p. miR-30c-5p was shown to promote the activation of nuclear factor (erythroid-derived 2)-like 2 (Nrf2) via the inhibition of Bach1. The re-expression of Bach1 reversed miR-30c-5p-mediated-cardioprotective effects against myocardial I/R injury in vivo or H/R injury in vitro. Overall, our results demonstrate that forced expression of miR-30c-5p exhibited beneficial effects against myocardial I/R injury through enhancement of Nrf2 activation via inhibition of Bach1. This work reveals a novel molecular mechanism for myocardial I/R injury at the miRNA level and suggests a therapeutic value of miR-30c-5p in treatment of myocardial I/R injury.

The butterfly genus Parnara (Hesperiinae: Baorini), of which some are major pests of economic crops (e.g., rice, wild rice stems and sugarcane), currently consists of 10 species and several subspecies and has a highly disjunct distribution in Australia, Africa, and Asia. We determined the systematic relationships and biogeographical history of the genus by reconstructing the phylogeny based on eight genes and 101 specimens representing all 10 recognized species. Four species delimitation methods (ABGD, bPTP, GMYC and BPP) were also employed to assess the taxonomic status of each species. Based on these results and analyses, we recognize 11 extant species in the genus. The status of the taxon P. naso poutieri (Boisduval, 1833) from Madagascar is revised as a distinct species, Parnara poutieri (Boisduval, 1833) stat. rev. The subspecies P. guttata mangala (Moore, 1866) syn. nov. is synonymized with P. guttata guttata (Bremer & Grey, 1853), while P. bada (Moore, 1878) is provisionally treated as a complex of two species, namely P. bada and P. apostata (Snellen, 1886). The monophyly of Parnara is strongly supported, with the following relationships: P. amaliaâ¯+â¯((P. monasiâ¯+â¯(P. poutieriâ¯+â¯P. naso))â¯+â¯((P. kawazoeiâ¯+â¯P. bada complex)â¯+â¯(P. gangaâ¯+â¯(P. ogasawarensisâ¯+â¯(P. guttataâ¯+â¯P. batta))))). Divergence time and ancestral range estimates indicate that the common ancestor of Parnara originated in an implausible area of Australia, Africa, and Oriental region in the mid-Oligocene and then differentiated in the late Miocene-late Pliocene. Dispersal and range expansion have played an important role in diversification of the genus in Asia and Afica. Relatively stable geotectonic plates at the time when most extant lineages appeared during the late Miocene-early Pliocene might have been the factor responsible for the relatively constant low dynamic rate of diversification within the group.

BACKGROUND: This study aimed to evaluate the predictive values of hepatitis B e antigen (HBeAg) and hepatitis B surface antigen (HBsAg) levels in 171 Chinese patients with chronic hepatitis B who received a 48-week course of pegylated interferon alfa-2b therapy at 1.5 mcg/kg. METHODS: HBsAg, HBeAg, and hepatitis B virus (HBV) DNA levels were measured at baseline and weeks 12, 24, 48, and 72. Clinical responses were defined as a combined response (CR, HBeAg seroconversion [sustained response, SR] combined with HBV DNA level <2,000 IU/mL at week 72). The positive predictive value and negative predictive value were calculated for HBsAg alone and/or combined with HBeAg and HBV DNA at weeks 12 and 24. RESULTS: Of 171 patients included, 58 (33.9 %) achieved a SR. Of patients who achieved a SR, 33 (56.9 %) achieved a CR. Totally 19.3 % (33/171) patients achieved CR and 80.7 % (138/171) patients did not. Patients with HBsAg <1500 IU/mL at week 12 had a 47.4 % chance of achieving an off-treatment SR and patients with a HBsAg decrease >1.5 logIU/mL at week 12 had a 54.5 % chance. Patients with HBsAg >20,000 IU/mL at weeks 12 and 24 had a 93.8 and 100.0 % chance, respectively, of not achieving a CR. An HBsAg level or changes at weeks 12 and 24, combined with HBeAg or HBV DNA, increased the chance for a SR and CR. CONCLUSIONS: On-treatment HBsAg quantification, alone or in combination with HBeAg or HBV DNA, predicted off-treatment SR and CR after 48 weeks of PEG-IFNα-2b therapy, and thus, may guide clinicians in making a therapeutic decision to continue or terminate the therapy.

To understand the evolutionary history of Lymantriinae and test the present higher-level classification, we performed the first broad-scale molecular phylogenetic analysis of the subfamily, based on 154 exemplars representing all recognized tribes and drawn from all major biogeographical regions. We used two mitochondrial genes (cytochrome c oxidase subunit I and 16S ribosomal RNA) and six nuclear genes (elongation factor-1α, carbamoylphosphate synthase domain protein, ribosomal protein S5, cytosolic malate dehydrogenase, glyceraldehyde-3-phosphate dehydrogenase and wingless). Data matrices (in total 5424 bp) were analysed by parsimony and model-based evolutionary methods (maximum likelihood and Bayesian inference). Based on the results of the analyses, we present a new phylogenetic classification for Lymantriinae composed of seven well-supported tribes, two of which are proposed here as new: Arctornithini, Leucomini, Lymantriini, Orgyiini, Nygmiini, Daplasini trib. nov. and Locharnini trib. nov. We discuss the internal structure of each of these tribes and address some of the more complex problems with the genus-level classification, particularly within Orgyiini and Nygmiini.

A preliminary review of the genus Agalope Walker, 1854 is presented. Two new genera are established for four species-groups: Rotundagalope S.-Y. Huang & Horie, gen. n. (type species Agalope immaculata Leech, 1898, for the immaculata species-group), Paragalope S.-Y. Huang & Horie, gen. n. (type species Chelura pica Wileman, 1910, for the pica, glacialis and dejeani species-groups). An additional new genus, Agacysma S.-Y. Huang & Horie, gen. n., related to Agalope and Elcysma, is erected for the new species Agacysma sinica S.-Y. Huang & Horie sp. n. (mainland China: Chongqing, Hubei & Shaanxi). Two new species of the genus Agalope are described: A. geoffi S.-Y. Huang & Horie sp. n. (mainland China: SE. Xizang) and A. liuzihaoi S.-Y. Huang & Horie sp. n. (mainland China: SE. Xizang), forming a species-group of their own which is clearly different from congeners in their male genitalia. The taxonomic issues between Paragalope haoi (S.-Y. Huang, 2022) comb. n. and P. bieti (Oberthür, 1886) comb. n. are discussed. Moreover, following the erection of Paragalope, the homonymy of Agalope glacialis Butler, 1881 and A. glacialis (Moore, 1872) ends; hence the replacement name of the former, A. butleri Owada & Horie, 2000 syn. n., is unnecessary and hence synonymized. The following new combinations are given: Rotundagalope immaculata (Leech, 1898) comb. nov., Paragalope ardjuna (Roepke, 1936) comb. nov., P. aurelia (Oberthür, 1923) comb. nov., P. basiflava (Moore, 1879b) comb. nov., P. bieti (Oberthür, 1886) comb. nov., P. chayuensis (S.-Y. Huang & Pan, 2022) comb. nov., P. haoi (S.-Y. Huang, 2022) comb. nov., P. owadai (S.-Y. Huang, 2022) comb. nov., P. pica (Wileman, 1910) comb. nov., P. trimacula (Matsumura, 1927) comb. nov., P. wangi (Owada, 1992) comb. nov., P. dejeani (Oberthür, 1893) comb. nov., P. lucia (Oberthür, 1923) comb. nov., P. glacialis glacialis (Moore, 1872) comb. nov., P. glacialis parthenie (Jordan, 1907b) comb. nov., P. glacialis angustifasciata (Hering, 1922) comb. nov., P. glacialis postfasciata (Holloway, 2011) comb. nov. A checklist of the species and genera mentioned in the present study is given. Adults and genitalia of the newly described taxa and related ones are illustrated.

Here, we present new molecular and morphological evidence that contributes towards clarifying the phylogenetic relations within the family Hesperiidae, and overcomes taxonomic problems regarding this family. First, nine new complete mitogenomes, comprising seven newly sequenced species and two samples of previously sequenced species collected from different localities, were obtained and assembled to analyze characteristics. The length of the mitogenomes ranges from 15,284 to 15,853 bp and encodes 13 protein-coding genes, two ribosomal RNA (rRNA) genes, 22 transfer RNA (tRNA) genes, and a control region. Two model-based methods (maximum likelihood and Bayesian inference) were used to infer the phylogenetic relationships. Based on the mitogenomic phylogenetic analyses and morphological evidence, we claim that the lineage that comprises two Asian genera, Apostictopterus Leech and Barca de Nicéville, should be a tribe Barcini stat. nov. of the subfamily Trapezitinae, Pseudocoladenia dea (Leech, 1894), P. festa (Evans, 1949), and Abraximorpha esta Evans, 1949 are considered distinct species. Finally, we suggest that Lotongus saralus chinensis Evans, 1932 should belong to the genus Acerbas de Nicéville, 1895, namely Acerbas saralus chinensis (Evans, 1932) comb. nov..

The name Striatochrista nom. n. is introduced as replacement for Striatella Volynkin & S.-Y. Huang, 2019. A new genus, Letrasilta S.-Y. Huang & Volynkin gen. n. is erected to include the Striatella cernyi species-group with the new species, L. ratnasambhava S.-Y. Huang, Volynkin & Yin sp. n. from Xizang, southwestern China designated as the type species. Based on the molecular phylogenetic analysis, the new genus is found to be sister to the clade (Aberrasine + ((Indiania + Idopterum) + Striatochrista nom. n.)) but is distinguished from all the relevant genera by the unique genitalia features. Letrasilta cernyi (Volynkin, 2018) comb. n. is also reported from India for the first time. Adults and genitalia of the aforementioned taxa are illustrated.

Two new species of Ochlodes Scudder, 1872, Ochlodespseudochraceus Zhu, Fan & Wang, sp. nov. and Ochlodescryptochraceus Zhu, Fan & Chiba, sp. nov., are found in China and described, and Ochlodesrikuchina (Butler, 1878) stat. rev. is restored. A lectotype is designated for Pamphilaochracea Bremer, 1861, and a neotype is designated for Pamphilarikuchina Butler, 1878. Overall, the two new species are similar to Ochlodesochraceus (Bremer, 1861). They, however, can be distinguished from the latter and other species in the genus: O.pseudochraceus has long radial spots in spaces R3-5, and the lateral process of the phallus gradually widens at the distal half in male genitalia; O.cryptochraceus has the lateral process of the phallus enlarged only at the distal tip. Based on the phylogenetic analyses of the mitochondrial COI gene, members of currently defined O.ochraceus are grouped into four clades. The genetic distances between O.pseudochraceus and O.ochraceus, O.cryptochraceus and O.ochraceus, O.rikuchina and O.ochraceus, and O.pseudochraceus and O.cryptochraceus are 3.2%, 2.1%, 1.9%, and 2.7%, respectively. Based on the molecular and morphological evidence, O.pseudochraceus, O.cryptochraceus, and O.rikuchina are treated to be distinct species. The adult habitus and male and female genitalia of the new species are illustrated as well as those of O.ochraceus and O.rikuchina.
ABSTRACT
BACKGROUND/AIMS: Adiponectin can initiate a broad range of metabolic and immunological effects. Little is known about the role of adiponectin in hepatitis B related liver disease and metabolic syndrome (MS). METHODOLOGY: We studied 138 patients with untreated chronic hepatitis B (CHB), who were from Beijing Ditan hospital in 2005 to 2009. According to MS, two groups (65 with MS vs. 73 without MS) were established. They were compared with characteristics and stained immunohistochemically for adiponectin and adiponectin receptor2 (adipoR2). RESULTS: In the group of CHB patients with MS, the levels of LDH, γ-GT, FPG, FINS, HOMA-IR, HOMA-ß, TG and HBeAg positive were significantly higher than those in the group without MS (p<0.05). Liver steatosis in the group with MS is significantly more severe than that in the group without MS (p<0.001). With binary logistic regression analyses, BMI and HOMA-IR showed independent predictors to MS in patients with CHB. In patients with chronic HBV, the insulin sensitizing adipokine adiponectin and its receptor AdipoR2 was associated with diabetes in patients with CHB and MS. CONCLUSIONS: Our findings showed the CHB patients with MS may be presence of more severe steatosis. MS in CHB patients may be closely correlated with insulin resistance and less effect of viruses. Reduced hepatic expression of adiponectin and adipoR2 might be of pathophysiological relevance in CHB patients with MS.

Polygonatum sibiricum Red. has been used as a medicinal herb and nutritional food in traditional Chinese medicine for a long time. It must be processed prior to clinical use for safe and effective applications. However, the present studies mainly focused on crude Polygonatum sibiricum (PS). This study aimed to investigate the chemical properties, blood-enriching effects and mechanism of polysaccharide from the steam-processed Polygonatum sibiricum (SPS), which is a common form of PS in clinical applications. Instrumentation analyses and chemistry analyses revealed the structure of SPS polysaccharide (SPSP). A mice model of blood deficiency syndrome (BDS) was induced by acetylphenylhydrazine (APH) and cyclophosphamide (CTX). Blood routine test, spleen histopathological changes, serum cytokines, etc. were measured. The spleen transcriptome changes of BDS mice were detected by RNA sequencing (RNA-seq). The results showed that SPSP consists predominantly of Gal and GalA together with fewer amounts of Man, Glc, Ara, Rha and GlcN. It could significantly increase peripheral blood cells, restore the splenic trabecular structure, and reverse hematopoietic cytokines to normal levels. RNA-seq analysis showed that 122 differentially expressed genes (DEGs) were obtained after SPSP treatment. GO and KEGG analysis revealed that SPSP-regulated DEGs were mainly involved in hematopoiesis, immune regulation signaling pathways. The reliability of transcriptome profiling was validated by quantitative real-time PCR and Western blot, and the results indicated that the potential molecular mechanisms of the blood-enriching effects of SPSP might be associated with the regulating of JAK1-STAT1 pathway, and elevated the hematopoietic cytokines (EPO, G-CSF, TNF-α and IL-6). This work provides important information on the potential mechanisms of SPSP against BDS.

New information of the genus Agalope Walker, 1854 from mainland China is presented. Three new species of the Agalope pica species-group are described: A. haoi S.-Y. Huang sp. n. from Weixi County, Yunnan, A. chayuensis S.-Y. Huang Pan sp. n. from Chayu County, Southeastern Xizang and A. owadai S.-Y. Huang sp. n. from Bomi and Jiali Counties, Southeastern and Eastern Xizang. The little-known Agalope aurelia Oberthr, 1923 and A. lucia Oberthr, 1923 were rediscovered, with the male of the latter reported for the first time. Based on the newly discovered male, Agalope lucia is found to be a close relative of A. dejeani, hence it is excluded from the A. pica species-group and transferred to the A. bieti species-group. A new species of the Agalope hyalina species-group is also described: A. jianqingi S.-Y. Huang sp. n. from Pianma, Western Yunnan. Adults and genitalia of the aforementioned and related taxa are illustrated. An updated checklist of the genus is also provided.

ABSTRACT
A new species of the genus Neopseustis Meyrick, 1909, Neopseustischentangensis S.Y. Huang & Chen sp. nov., which was confirmed by both morphological and molecular methods, is described from Xizang, China. This is currently the westernmost species in Asia of the primitive lepidopteran family Neopseustidae. The new species is externally reminiscent of N.moxiensis Chen & Owada, 2009; however, it can be easily distinguished from the latter by comparison of the male genitalia and is further distinguished by the large genetic distance in DNA barcodes (COI). The adult and genitalia of the new and similar species have been illustrated. Utilizing our new data, a new classification of the genus is provided, with its members subdivided into four species groups: the meyricki-group, the moxiensis-group, the bicornuta-group, and the chentangensis-group, which are supported by both molecular and morphological evidence. A checklist of the genus and a key to the species groups are also provided.
