Abstract
Two new triterpenoids and two new sterols, named euphyperins A-D (1–4), including an oleanane-type triterpenoid (1), a lupane-type nortriterpenoid (2), and two cholestane-type steroids (3 and 4), along with five known compounds (5–9) were isolated from the twigs and leaves of Euphorbia hypericifolia. Euphyperin B (2) represents a rare lupane-type nortriterpenoid, and euphyperin C (3) is a novel 8,14-secocholestane-type steroid. Euphyperin A (1) exhibited moderate PTP1B inhibitory activity with an IC50 = 17.05 ± 1.12 μg/mL.

Abstract
Chemical investigation into the minor constituents of Aphanamixis grandifolia yielded three new diterpenoid dimers, aphadilactones E-G (1-3) featuring a new carbon skeleton. Their structures and absolute configurations were fully established by comprehensive spectroscopic data analysis and ECD calculation. Discovery of another two new dimers (4 and 5) suggested the structure of recently reported aphanamene A to be re-investigated. Compounds 1-5 showed moderate antimalarial activities with low micromolar IC50 values.

Abstract
Thirteen new hydroxylated calyciphylline A-type Daphniphyllum alkaloids (1-13) were isolated from an ethanolic extract of Daphniphyllum himalense. These structures were characterized on the basis of spectroscopic data analysis, especially from their 2D NMR spectra. Oxidation at the C-3, C-9, C-11, and C-12 positions is reported for the first time for this class of compounds. Selective compounds showed low inhibitory rates against three kinase enzymes, PTP1B, aurora A, and IKK-β, at a concentration of 20 μg/mL.

Abstract
Sixteen new limonoids, named ciparasins A-P (1-16), comprising three structural categories of trijugin-type (1-7), cipadesin-type (8-15), and prieurianin-type (16) compounds, as well as 15 known limonoid analogues (17-31), were isolated from Cipadessa cinerascens. Ciparasins E-G (5-7) were found to possess a rare γ-hydroxylbutenolide moiety at C-17. Ciparasins B (2) and P (16) showed significant anti-HIV activities, with EC50 values of 5.5 ± 0.6 (SI >7.2) and 6.1 ± 0.7 (SI >6.5) μM, respectively.

Abstract
The prevalence of Y chromosome microdeletions among azoospermic, severe oligozoospermic, moderate oligozoospermic, and mild oligozoospermic patients with varicocele-related and idiopathic infertility shows conflicting data in Asian countries. We aimed to detect this frequency in Northeast China, and investigated spermatogenic defects whether associated with varicocele or Y chromosome microdeletions. All samples underwent a thorough physical examination, semen analysis, and PCR analyses for Y chromosome microdeletions. We randomly selected 150 infertile non-obstructive azoospermic patients with left varicocele (Group 1), 150 idiopathic non-obstructive azoospermic infertility patients (Group 2), 150 infertile severe oligozoospermic patients with left varicocele (Group 3), 150 idiopathic severe oligozoospermic infertility patients (Group 4), 150 infertile moderate oligozoospermic patients with left varicocele (Group 5), 150 idiopathic moderate oligozoospermic infertility patients (Group 6), 150 infertile mild oligozoospermic patients with left varicocele (Group 7), 150 idiopathic mild oligozoospermic infertility patients (Group 8), and 60 healthy unrelated men with proven fertility were recruited as control subjects (Group 9). We observed that our samples from Northeastern China had a higher frequency of microdeletions among the non-obstructive azoospermic individuals with varicocele, as compared with other Asian countries. Furthermore, the spermatogenic defect is due to the underlying Y chromosome microdeletion, and not the varicocele itself. Although varicocele is not the cause of male infertility, it may be associated with male infertility in the Northeastern Chinese population.
