Study Question: To evaluate the most ideal interval between blastocyst biopsy and vitrification in preimplantation genetic screening (PGS). Study Design, Size, Duration: This is a retrospective study and total 224 patients underwent the PGS from 2012 Dec. to 2015 Mar. All of patients underwent blastocyst vitrification after biopsy and 1~2 euploid blastocyst for transfer after warming. The primary outcome measures were the implantation and pregnancy rates per PGS-frozen embryo transfer cycle. Materials, Setting, Methods: The blastocyst grading including grade 4, 5 and 6 (according to Gardner grading system) on day 5 or day 6 were selected for trophectoderm biopsy. All blastocyst underwent vitrification immediately (interval: 0.5 hour) or 1 to 7 hours after biopsy. At the time of vitrification the grade of blastocyst expansion was also recorded. All patients were divided into two groups according to the grade of expanded (Group1: ≤1/2 expansion (n=41), Group2: ≥3/4 expansion (n=183)). Furthermore, combined two factors including the interval and morphology of blastocyst after biopsy, all patients were further divided into interval 1 (<3 hours and ≤1/2 expansion) and interval 2 (≥3 hours and ≥3/4 expansion). The morphologically best euploid blastocyst(s) (1~2 embryos) was/were selected first for transfer on the next cycle. Main Results: Assessment morphology of blastocyst after biopsy in different interval, at 0.5 hour after biopsy, 100% blastocyst was non-expansion; at 1 hour after biopsy, only 17% blastocyst was 3/4 expansion or all-expansion; at 3 hours after biopsy, 86% blastocyst was 3/4 expansion or all-expansion and after 5.5 hours, 100% blastocyst was all-expansion or hatching. All blastocysts were survival (100%, 359/359) after warming. The mean of embryo transfer number between all groups were no significantly difference. The implantation rate in Group2 (63.4%) was significantly higher than that in Group1 (46.9%, p=0.014). The pregnancy rates in Group4 (73.8%) was sig-nificantly higher than that in Group1 (51.2%, p=0.004). The implantation and pregnancy rates in the group of embryo ≥3/4 expansion combined with ≥3 hours after biopsy (63.6%, 178/280; 73.8%, 127/172) were significantly higher than that in the group of ≤1/2 expansion with <3 hour (45.6, 26/57; 50.0%, 18/36; p=0.0113 and p=0.0056, respectively). Conclusion: The most ideal interval between biopsy and vitrification was least 3 hours and ≥3/4 expansion of blastocyst after biopsy could improve the implantation and pregnancy rates for PGS.

All orchids maintain an obligate relationship with mycorrhizal symbionts during seed germination. In most cases, germination-enhancing fungi have been isolated from roots of mature plants for conservation and cultivation purposes. To understand the germination biology of Dendrobium devonianum, an over-collected medicinal orchid, the seeds of D. devonianum were inoculated with a fungal strain (FDd1) isolated from naturally occurring protocorms of D. devonianum and two other germination-enhancing fungal strains (FDaI7 and FCb4) from D. aphyllum and Cymbidium mannii, respectively. The fungal strain was isolated from five protocorms of D. devonianum and identified as a species of the genus Epulorhiza. In germination trials, treatments with all of the three fungal strains showed a significant promoting effect on seed germination and protocorm formation, compared with the control treatment (no inoculation). However, FDd1 fungal strain showed the greatest effectiveness followed by FDaI7 and FCb4. For all inoculation and control treatments, seeds developed to protocorms regardless of the presence of illumination, whereas protocorms did not develop to seedlings unless illumination was provided. The results of our manipulative experiments confirmed the hypothesis that mycorrhizae associated with orchid seedlings are highly host-specific, and the degree of specificity may be life stagespecific under in vitro conditions. The specific mycorrhizal symbionts from protocorms can enhance restoration efforts and the conservation of orchids such as D. devonianum.

Purpose: High-dose-rate brachytherapy (HDR-BT) with external beam radiation therapy (EBRT) is a common treatment option for locally advanced prostate cancer. Quality of life is an important factor when discussing therapy options for high-risk prostate cancer. This study evaluated adverse effects and health-related quality of life (HRQOL). Materials and Methods: Ninety male patients (median age, 71 years; range, 50 to 79 years) with high-risk prostate cancer underwent HDR-BT after EBRT between December 2009 and January 2017 with a median follow-up of 43 months. A total of 57 patients (69.5%) answered the European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life of Cancer Patients questionnaire (QLQ-C30; ver. 3.0), and 8 patients died during follow-up. In order to put the results of this study in context, we compared the results with reference data from the EORTC QLQ-C30 Scoring Manual. Correlations of prostate-specific antigen (PSA) values, International Prostate Symptom Score, and HRQOL measures were calculated. Results: The study participants reported better physical functioning and better global health compared with the reference data, but worse social, role, and cognitive functioning. We found negative statistically significant correlations between the last-measured PSA value and social functioning (p>0.01), cognitive functioning, pain, and constipation (all p<0.05). Toxicity rates were 10.0% for gastrointestinal and 12.2% for genitourinary adverse effects. All reported complications for toxicity were Grade I. Conclusions: The described therapy results in high biochemical control rates with minimal adverse effects. Compared with reference groups, the HRQOL of this study cohort was acceptable. PSA values during follow-up seem to be a possible indicator to influence HRQOL.

A facile and effective approach based on magnetic separation was developed for the adsorption of Rhodamine B (RhB) from aqueous solution using magnetic oxidized multi-walled carbon nanotubes (magnetic o-MWCNTs) as adsorbent. The magnetic o-MWCNTs were simply synthesized by assembling magnetic nanoparticles onto the oxidized MWCNTs. Adsorption conditions such as pH values, the dosage of adsorbent added and adsorption time were investigated and optimized to achieve the best removal value. In addition, kinetics, adsorption isotherms and adsorption thermodynamics were studied to understand the mechanism by which the magnetic o-MWCNTs adsorbed RhB. The results indicated that the proposed method based on magnetic o-MWCNTs as magnetic absorbent was rapid and e±cient for the removal of RhB. Furthermore, the magnetic o-MWCNTs could be easily removed after adsorption process and regenerated through desorption by ethanol.

Background: The aim of this study was to investigate whether family history of cancer is associated with head and neck cancer risk in a Chinese population. Materials and Methods: This case-control study included 921 cases and 806 controls. Recruitment was from December 2010 to January 2015 in eight centers in East Asia. Controls were matched to cases with reference to sex, 5-year age group, ethnicity, and residence area at each of the centers. Results: We observed an increased risk of head and neck cancer due to first degree family history of head and neck cancer, but after adjustment for tobacco smoking, alcohol drinking and betel quid chewing the association was no longer apparent. The adjusted OR were 1.10 (95% CI=0.80-1.50) for family history of tobacco-related cancer and 0.96 (95%CI=0.75-1.24) for family history of any cancer with adjustment for tobacco, betel quid and alcohol habits. The ORs for having a first-degree relative with HNC were higher in all tobacco/alcohol subgroups. Conclusions: We did not observe a strong association between family history of head and neck cancer and head and neck cancer risk after taking into account lifestyle factors. Our study suggests that an increased risk due to family history of head and neck cancer may be due to shared risk factors. Further studies may be needed to assess the lifestyle factors of the relatives.

Conventional turbine blade machining technology has to face some challenges on production efficiency, quality and environmental impact. So a new machining technical solution for thin-walled turbine blade is presented. Technical problems associated with the precise machining of turbine blade are discussed in detail. On the basis of analysis with existing demerits, we propose a new fixture optimization and precise machining schema for turbine blade. In the proposed technical methodology, geometric locating tolerance analysis and FEM based structural deformation prediction methods are integrated into one framework to improve the machining performance of thin-walled turbine blade. An automatic machining station of turbine blade is also developed. Promising technical capability of this system is demonstrated and validated by real machining experiments.

In this study, amino-functionalized multi-walled carbon nanotubes (MWCNTs-NH2) were successfully synthesized via an improved method and used for removal of organic dyes in aqueous solution. The synthesized MWCNTs-NH 2 were characterized by Fourier transform infrared (FTIR) spectroscopy, thermogravimetric analysis (TGA), scanning electron microscope (SEM), etc. The adsorption capacity and selectivity of MWCNTs-NH 2 for organic dyes was evaluated using rhodamine B (RhB), malachite green (MG), methyl orange (MO) and congo red (CR) as models. The selective adsorption toward anionic dyes was found for the MWCNTs-NH2 , and MO was selected as a typical anionic dye to deeply investigate the adsorption kinetics, equilibrium isotherms and thermodynamic parameters of the adsorption process. The adsorption kinetics and equilibrium isotherms data fitted well with the pseudo-second-order kinetic equation and Langmuir isotherm model. The thermodynamics study revealed that the adsorption of MO onto MWCNTs-NH2 was spontaneous, exothermic and physisorptive in nature. The results indicated that MWCNTs-NH2 are promising nanomaterials for removal of anionic dyes from industrial wastewater.
