Objective To explore the gender difference in Chinese version of autism spectrum rating scale (ASRS)-in terms of parents and teacher rating.Methods A total of 701 children (380 boys,321 girls;6 -11 years old)were recruited from one Primary School in Minhang District of Shanghai.The parents and teachers of the children completed the ASRS.While the data were imput into the database,the software automatically calculated T -standard score according to the formula for the raw score of screening scale,treatment scale,and Diagnostic and Statistical Manual of Mental Disorders -Ⅳ -Turning Reversion scale.In the end,the gender differences in Chinese version of ASRS for both parents and teacher ratings were analyzed.Results A total of 671 parents rating scale were retrieved (response rate was 95.7%),involving 368 boys (54.8%);685 for teacher rating scale (response rate was 97.7%), involving 381 boys (55.6%).No significant difference was observed in the distribution of gender(P >0.05).Minor influence of age was found among ASRS sub -scales for both parents and teacher ratings in boys and girls (parent rating scale r =-0.219 1 to -0.124 4,teacher rating scale r =-0.328 0 to -0.120 0).In parent and teacher ver-sion of ASRS,boys had higher T -standard scores in all subscales by 1 -3 and 2 -4 points than those in girls,respec-tively,and apart from abnormal behavior,adult socialization,behavioral rigidity,and sensory sensitivity there was no sig-nificant difference(all P >0.05)in parents rating scale while others had significant differences(all P <0.05),and all sub -scales had significant difference in teacher rating scale(all P <0.01).Conclusions The T -standard scores of both ASRS questionnaire has the gender differences in ASRS subscales,so it is necessary for researchers to understand the Chinese version of ASRS questionnaire from different angles.

OBJECTIVETo investigate the precise locations of the blood vessels and nerves surrounding the seminal vesicles (SV) in men and provide some anatomical evidence for SV-related minimally invasive surgery.

METHODSWe observed the courses and distribution of the blood vessels and nerves surrounding SVs and obtained the data for positioning the SV neuroplexes in 20 male pelvises.

RESULTSOne branch of the neuroplexes was distributed to the SVs bilaterally with the neurovascular bundles, (2.85 ± 0.18) cm from the median sulcus of the prostate (MSP), while another branch ran through the Denonvillier fascia behind the SV, (0.81 ± 0.06) cm from the MSP. The arterial SVs (ASV) originated from the inferior vesical artery and fell into 4 types, 55% going directly to the SVs as one branch, 15% running between the SV and the ampulla of the deferent duct as another branch, 25% downward as 2 branches to the SV and between the SV and the ampulla of the deferent duct respectively, and 5% as the other ASVs. The shortest distance from the ASV through the prostatic neuroplexus to the posterior SV was (1.08 ± 0.09) cm.

CONCLUSIONIn SV resection, neuroplexus injury can be reduced with a bilateral distance of < 2.85 cm and a posterior distance of < 0.81 cm from the MSP, and so can bleeding by vascular ligation between the SV and the ampulla of the deferent duct.

The chemical consitituents from cytotoxic fraction of the Callicarpa nudiflora extract were isolated and purified by a combination of HP-20 macroporous resin, silica gel and Sephadex LH-20 column chromatographies. The structures were elucidated on the basis of the spectroscopic data and comparison of their spectroscopic data with reported data. The cytotoxicity was evaluated by the MTT assay. The 50% and 70% EtOH elutions of EtOH-extract showed significant cytotoxic activities, leading to the isolation of twelve compounds, which were identified as luteoloside(1), lutedin-4'-O-β-D-glucoside(2), 6-hydroxyluteolin-7-O-β-glucoside(3), lutedin-7-O-neohesperidoside(4), rhoifolin (5), luteolin-7, 4'-di-O-glucoside (6), forsythoside B (7), acteoside (8), alyssonoside (9), catalpol(10), nudifloside(11), and leonuride(12). Compounds 3-6, 10 and 12 were isolated from this genus for the first time, and compound 9 was isolated from this plant for the first time. The cytotoxicity assay demonstrated that flavonoids 1-6, in various concentrations, showed monolithic proliferation inhibitory activities against Hela, A549 and MCF-7 cell lines. Compounds 3, 5 and iridoid glycoside 11 possessed higher cytotoxicacivities. In short, flavonoids are the main components of cytotoxic extract from C. nudiflora, while phenylethanoid glycosides are the predominant ingredient but inactive to cancer cell lines. In addition, the minor iridoid glycoside expressed weak cytotoxic activity.
