Table1_Bu-Fei-Huo-Xue capsule alleviates bleomycin-induced pulmonary fibrosis in mice through modulating gut microbiota.DOCX
No full textIntroduction: Bu-Fei-Huo-Xue capsule (BFHX) has been used to treat pulmonary fibrosis (PF) in clinic. However, the mechanism of Bu-Fei-Huo-Xue capsule on pulmonary fibrosis remains unclear. Recent studies have shown that the changes in gut microbiota were closely related to the progression of pulmonary fibrosis. Modulating gut microbiota provides new thoughts in the treatment of pulmonary fibrosis.Methods: In this study,a mouse model of pulmonary fibrosis was induced using bleomycin (BLM) and treated with Bu-Fei-Huo-Xue capsule. We firstly evaluated the therapeutic effects of Bu-Fei-Huo-Xue capsule on pulmonary fibrosis model mice. Besides,the anti-inflammatory and anti- oxidative effects of Bu-Fei-Huo-Xue capsule were evaluated. Furthermore, 16S rRNA sequencing was used to observe the changes in gut microbiota in pulmonary fibrosis model mice after Bu-Fei-Huo-Xue capsule treatment.Results: Our results showed that Bu-Fei-Huo-Xue capsule significantly reduced the collagen deposition in pulmonary fibrosis model mice. Bu-Fei-Huo-Xue capsule treatment also reduced the levels and mRNA expression of pro-inflammatory cytokines and inhibited the oxidative stress in lung. 16S rRNA sequencing showed that Bu-Fei-Huo-Xue capsule affected the diversity of gut microbiota and the relative abundances of gut microbiota such as Lactobacillus, Lachnospiraceae_NK4A136_group, and Romboutsia.Conclusion: Our study demonstrated the therapeutic effects of Bu-Fei-Huo-Xue capsule on pulmonary fibrosis. The mechanisms of Bu-Fei-Huo-Xue capsule on pulmonary fibrosis may be associated with regulating gut microbiota.</p

Parisoperla oncocauda Huo & Du 2020, comb. nov.
No full textParisoperla oncocauda (Huo & Du, 2018), comb. nov. Isoperla oncocauda Huo & Du, 2018. Type locality: Tianmu Mountain, Zhejiang Province. Distribution: China (Zhejiang). Mature nymph: Body length c.a. 16 mm. Gills absent. Body covered with dark hair. Maculation of head and thorax typical of other Isoperlinae; M line and ecdysial line obvious. Mouthpart as shown in Fig. 3. Ventral tibial fringe absent. Wing pads subtriangular. Abdomen with a longitudinal pale band; paraprocts short; cerci long with setal fringe (Fig. 2). Material examined: 1 nymph, China, Zhejiang Province, Lin’an City, Tianmu Mountain Nature Reserve, Wuliting, 861m, 30°20.228′N, 119°26.136′E, 2018-IV-22, leg. Gao Peng. The same locality and data as holotype and paratypes of this species (ICYZU). Remarks: Only a single nymph available of the new genus from Tianmu Mountain was available for study. In the new genus, the Y-arms of the mesosternum and mandibles appear to be most similar to nymphs of Calliperla and Isoperla (Szczytko & Stewart 1984, Stewart & Stark 1993). The lacinia of P. oncocauda is similar to C. luctuosa (Banks, 1906) with the apex curved and inner margin straight (Szczytko & Stewart 1984), but the inner lacinial setal row of P. oncocauda is only present on the anterior apex angle, not reaching the base and sparser than C. luctuosa (about 8 thick setae and 20 fine hairs). No additional seta or setal patches occur on the surface of the lacinia.Published as part of Huo, Qing-Bo & Du, Yu-Zhou, 2020, A new genus and two new species of stoneflies (Plecoptera: Perlodidae) from Guizhou Province, China, pp. 470-480 in Zootaxa 4718 (4) on page 471, DOI: 10.11646/zootaxa.4718.4.2, http://zenodo.org/record/360263

Parisoperla leigongshana Huo & Du 2020, sp. nov.
No full textParisoperla leigongshana Huo & Du, sp. nov. Male: Forewing length ca. 11.2 mm, hindwing length 10.2 mm, body length 9.8 mm; general color brown (Fig. 11). Head brown, ocellar and frontoclypeal area dark brown. Antennae and palpi brown. Pronotum disc brown, rugosities present medially (Fig. 12A). Legs brown; wings hyaline, veins dark brown. Abdomen dark brownish and slightly sclerotized. Posterior margin of tergum 10 darkly sclerotized, recessed medially and rearward, extending as a process, with wide lateral grooves on surface, and perpendicular to tergum 10 posteriorly (Fig. 12B, Fig. 13). Vesicle reduced as a patch of bristles on posterior margin of sternum 8 (Fig. 12C). Paraprocts slender and lightly sclerotized. Female: Unknown. Egg: Unknown. Nymph: Unknown. Type material: Holotype: ♂, China, Guizhou Province, Leigongshan Nature Reserve, beside an unnamed road, 1198m, 26.3616N, 108.1650E, 2018-IV-22, leg. Du Yu-Zhou, Chen Zhi-Teng. Etymology: The scientific name refers to the type locality. Diagnosis: This species can be distinguished by the slender paraprocts and the shape of posteromedial margin of male tergum 10. Remarks: This species is similar to P. kuankuoshuiensis, except for the longer process on male terminalia and smaller paraprocts (Fig. 14). It is also similar to P. oncocauda, but the sclerotized areas on terminalia are different in shape. The posteromedial margin of tergum 10 of the male of P. leigongshana is narrowed in dorsal view. Parisoperla oncocauda bears a process which is wider at posteromedial tergal margin and tapers distally.Published as part of Huo, Qing-Bo & Du, Yu-Zhou, 2020, A new genus and two new species of stoneflies (Plecoptera: Perlodidae) from Guizhou Province, China, pp. 470-480 in Zootaxa 4718 (4) on pages 477-478, DOI: 10.11646/zootaxa.4718.4.2, http://zenodo.org/record/360263

Parisoperla Huo & Du 2020, gen. nov.
No full textParisoperla Huo & Du, gen. nov. Diagnosis: Small size, body length 10~ 15 mm; macropterous, wing length 10~ 15 mm, general color dark brown; triocellus, area between posterior ocelli to compound eyes yellow brown. Pronotum width twice its length, darkcolored medially with rugosities, with a smooth longitudinal band present among the centerline. Terga 9–10 of male heavily sclerotized posteriorly, posteromedial margin of tergum 10 undivided, with a developed sclerotized process (Fig. 1 A–B) with wide lateral grooves on surface. Vesicle on sternum 8 reduced. Aedeagus membranous, short columnar, without any sclerites but covered ventrally by patches of fine spines. Female coloration similar to male, posterior margin of tergum 10 usually sclerotized and extending as a process like the male (Fig. 1 C–D). Subgenital plate rounded or short triangle, often with a median notch apically. Type species: Parisoperla oncocauda (Huo & Du, 2018). Etymology: This name indicates “ Para -” and “ Isoperla ”, means that “similar to Isoperla ”. Remarks: We previously treated P. oncocauda as a species of Isoperla Banks, 1906 based on the wing venation (Banks 1906) and aedeagal morphology (Sandberg & Kondratieff 2013, Szczytko & Kondratieff 2015). The wing venation and the paraprocts of Parisoperla are most similar to Isoperla, indicating a placement in the subfamily Isoperlinae. Within the Isoperlinae, several genera such as Calliperla Banks, 1948, Cascadoperla Szczytko & Stewart, 1979, Clioperla Needham & Claassen, 1925, Cosumnoperla Szczytko & Bottorff, 1987, Kaszabia Raušer, 1968 and Mesoperlina Klapálek, 1921 are also similar to the new genus. However, the male tergum 10 of Clioperla and Mesoperlina is cleft. The male of Kaszabia can be distinguished by a pair of tergal processes of the abdomen (although these processes are not a unique character of this subfamily, present also I. distincta Nelson, 1976 a Nearctic species of Isoperla) (Teslenko & Zhiltzova 2009, Judson & Nelson 2012, Szczytko & Kondratieff 2015); The monotypic Calliperla from western North America has the male tergum 10 short and broad, crescent-shaped, with a terminal process as well, but the process curving forward and upward, just as similar as Cosumnoperla. The aedeagus of Calliperla and Cosumnoperla are more complex in structure than the new genus (Bottorff 2007, Szczytko & Stewart 1984). Discussion: Geographically, the 15 known Chinese Isoperla species are mainly distributed in Palaearctic Region of China. Whereas Parisoperla is apparently restricted to Guizhou and Zhejiang provinces, which are considered the northern portion of the Oriental Region (Ma 1959, Zhang 2011). Therefore, we speculate that the genus may be an Oriental group of stoneflies.Published as part of Huo, Qing-Bo & Du, Yu-Zhou, 2020, A new genus and two new species of stoneflies (Plecoptera: Perlodidae) from Guizhou Province, China, pp. 470-480 in Zootaxa 4718 (4) on page 471, DOI: 10.11646/zootaxa.4718.4.2, http://zenodo.org/record/360263
