The complete mitochondrial genome of Ampittia dioscorides （Lepidoptera： Hesperiidae） was determined. The sequenced genome is a circular molecule of 15313 bp, containing 13 protein-coding genes （PCGs）, 22 tRNA genes, two rRNA genes, and an A ＋ T-rich region. The gene arrangements and transcribing directions are identical to those in most of the reported lepidopteran mitogenomes. The base composition of the whole genome and genes or regions are also similar to those in other lepidopteran species. All the PCGs are initiated by typical ATN codons; the exception being CO1, which begins with a CGA codon. Eight genes （ND2, ATPase8, ATPase6, COIII, ND5, ND4L, ND6, and Cytb） end with a TAA stop codon, and two genes （ND1 and ND3） end with TAG. The remaining three genes （CO1 and COIl, which end with TA-, and ND4, which ends with T-） have incomplete stop codons. All tRNAs have the typical clover-leaf structure of mitochondrial tRNAs, with the exception of tRNAser（AGY）. On the basis of the concatenated nucleotide and amino acid sequences of the 13 PCGs and wingless gene of 22 butterfly species, maximum parsimony （MP） and Bayesian inference （BI） trees were constructed, respectively. Both MP and BI trees had the same topological structure：（（（（Nymphalidae ＋ Danaidae）＋ Lycaenidae）＋ Pieridae）＋ Papilionidae）＋ Hesperiidae）. The results provide support for Hesperiidae as a superfamily-level taxon.

Background Vaccinium uliginosum L. is a type of blueberry found in the Chinese Changbai Mountains. We extracted Vaccinium uliginosum Anthocyanins （***） to investigate its bioactivity on suppressing cancer cells. Methods *** was extracted under different conditions of temperature （10℃-35℃）, pH 1.0-3.0, and diatomaceous earth （1.0 g-3.0 g）, followed by a HPLC analysis for the determination of the ingredients. Its anticancer bioactivities on human colon and colorectal cancer cells （DLD-1 and COLO205） were compared with those on Lonicera caerulea Anthocyanins （***） and Vaccinium myrtillus Anthocyanins （***）, using cell viability assays, DNA electrophoresis and nuclear morphology assays. Results The optimum process of *** extraction involved conditions of temperature 20℃, pH 2.0, and diatomaceous earth 1.0 g/50 g of fruit weight. *** contained 5 main components： delphinidin （40.70±1.72）%, cyanidin （3.40±0.68）%, petunidin （17.70±0.54）%, peonidin （2.90±0.63）% and malvidin （35.50±1.11）%. The malvidin percentage was significantly higher （P 〈0.05） than it in ***. *** complied with a dose-dependent repression of cancer cell proliferation with an IC50 （50% inhibitory concentration） value of 50 μg/ml, and showed greater anticancer efficiency than AL. cae and Av. myr under the same cell treatment conditions. These observations were further supported by the results of nuclear assays. Conclusions The extraction protocol and conditions we used were effective for anthocyanin extraction. *** could be a feasible practical research tool and a promising therapeutic source to suppress human colon or colorectal cancers.

The aim of this study was to compare the intraoperative difference in anatomic details between Ioupe-assisted and microscopic varicocelectomy within the same spermatic cord. Between April 2011 and August 2011, 26 men with 33 sides containing grade 2-3 varicocele were enrolled in this study. First, one surgeon performed the open inguinal varicocelectomy under x 3.5 Ioupe magnification. The presumed vascular channels and lymphatics were isolated and marked without ligation. Another surgeon then microsurgically dissected and checked the same spermatic cord using an operating microscope to judge the results in terms of the ligation of the internal spermatic veins and the preservation of the arteries and lymphatics. There were significant differences in the average number of internal spermatic arteries （1.51 vs 0.97）, internal spermatic veins （5.70 vs 4.39） and lymphatics （3.52 vs 1.61） between the microscope and Ioupe-assisted procedures （P 〈 0.001, P 〈 0.001, P 〈 0.001, respectively）. Meanwhile, in varicocele repair with Ioupe magnification, an average of 1.30 β± 1.07 （43/33） internal spermatic veins per side were missed, among the overlooked veins, 1.12 ± 0.93 （37/33） were adhered to the preserved testicular artery, as well as 0.55 ± 0.79 lymphatics and 0.36 ± 0.55 arteries that were to be ligated. In conclusion, microscopic varicocelectomy could preserve more internal spermatic arteries and lymphatics and could ligate more veins than the Ioupe-assisted procedure. To some degree, Ioupe magnification is inadequate for the reliable identification and dissection of the tiny vessels of the spermatic cord, as most of the overlooked veins were adhered to the preserved testicular artery.
