| 1 | Adsorption/desorption of toluene on a hypercrosslinked polymeric resin in a highly humid gas stream显示文摘In many sources of volatile organic compounds (VOCs), large amounts of water vapor come from the air and the reactors. The relative humidity (RH) of exhaust gas is normally >60% and is supersaturated. Maintaining the property of adsorbent on VOCs in a highly humid gas stream is a serious industrial problem. In this study, the adsorption/desorption behavior of toluene in a micro-mesoporous polymeric resin was investigated in a highly humid environment to explore the influence of abound water vapor on resin adsorption and regeneration. This resin could selectively adsorb toluene at an RH of 80%, and its adsorption property was unaffected by the presence of water vapor. In the case of humidity saturation, the resin displayed a high adsorption capacity at a moisture content of <30%. Therefore, the polymer resin is an excellent water-resistant adsorbent of VOCs. In the regenerative experiment, the resin maintained its original adsorption capability after four adsorption/ desorption cycles of toluene purging with nitrogen gas at 120℃. The resin exhibited excellent regeneration performance at high humidity. | Bing Zhou Bin Sun Wenjuan Qiu Ying Zhou Junqian He Xiao'ai Lu Hanfeng Lu | 2019 | Chinese Journal of Chemical Engineering2019，27，4： | 6 |
| 2 | Is new American Thyroid Association risk classification for hereditary medullary thyroid carcinoma applicable to Chinese patients? A single-center study显示文摘Objective: The American Thyroid Association(ATA) proposed a new risk classification for hereditary medullary thyroid carcinoma(MTC) in 2015. This study aimed to assess whether the new guidelines are suitable for the Chinese population, and reported our experience on prophylactic thyroidectomy.Methods: A total of 73 patients from 22 families were screened as rearranged during transfection(RET) mutation carriers from 2010 to 2016 in Cancer Hospital, Chinese Academy of Medical Science; the medical history for each patient was collected. Based on the initial treatment, we identified the risk factors for poor prognosis by univariate and multivariate logistic regression. Then, 4 RET mutation carriers were enrolled for prophylactic thyroidectomy,and their pathological data and follow-up outcomes were recorded.Results: In univariate and multivariate logistic regression analyses, age at initial surgery and risk classification were significant risk factors for stage Ⅲ/Ⅳ hereditary MTC at initial diagnosis. The likelihood was increased by 11.6% per year of age at initial surgery [95% confidence interval(95% CI), 1.040–1.198; P=0.002). It was 7.888 times more likely to have Ⅲ/Ⅳ stage disease for ATA highest risk patients, compared to ATA moderate risk individuals(95% CI, 1.607–38.717; P=0.003). Postoperative pathological results showed all 4 multiple endocrine neoplasia type 2A(MEN2A) patients had C-cell hyperplasia(CCH); multifocal malignancies were detected in 3 of them. All 4 patients were cured biochemically, and none developed permanent hypoparathyroidism.Conclusions: In Chinese individuals, hereditary MTC aggressiveness is in line with the new ATA risk classification. Germline RET gene mutation carriers should undergo prophylactic thyroidectomy according to basal serum calcitonin levels. | Xiwei Zhang Dangui Yan Junyi Wang Hanfeng Wan Yongxia Zhang Yabing Zhang Yuqin He Wensheng Liu Bin Zhang | 2017 | Chinese Journal of Cancer Research2017，29，3： | 5 |
| 3 | Preparation of hydrophobic hierarchical pore carbon–silica composite and its adsorption performance toward volatile organic compounds显示文摘Carbon–silica materials with hierarchical pores consisting of micropores and mesopores were prepared by introducing nanocarbon microspheres derived from biomass sugar into silica gel channels in a hydrothermal environment.The physicochemical properties of the materials were characterized by nitrogen physical adsorption(BET),scanning electron microscopy(SEM),and thermogravimetric(TG),and the adsorption properties of various organic waste gases were investigated.The results showed that microporous carbon materials were introduced successfully into the silica gel channels,thus showing the high adsorption capacity of activated carbon in high humidity organic waste gas,and the high stability and mechanical strength of the silica gel.The dynamic adsorption behavior confirmed that the carbon–silica material had excellent adsorption capacity for different volatile organic compounds(VOCs).Furthermore,the carbon–silica material exhibited excellent desorption characteristics:adsorbed toluene was completely desorbed at 150℃,thereby showing superior regeneration characteristics.Both features were attributed to the formation of hierarchical pores. | Xiaoai Lu Junqian He Jing Xie Ying Zhou Shuo Liu Qiulian Zhu Hanfeng Lu | 2020 | Journal of Environmental Sciences2020，32，1： | 4 |

| 8 | Development of an Agrobacterium-mediated CRISPR/Cas9 system in pea(Pisum sativum L.)显示文摘Pea(Pisum sativum L.)is an annual cool-season legume crop.Owing to its role in sustainable agriculture as both a rotation and a cash crop,its global market is expanding and increased production is urgently needed.For both technical and regulatory reasons,neither conventional nor transgenic breeding techniques can keep pace with the demand for increased production.In answer to this challenge,CRISPR/Cas9 genome editing technology has been gaining traction in plant biology and crop breeding in recent years.However,there are currently no reports of the successful application of the CRISPR/Cas9 genome editing technology in pea.We developed a transient transformation system of hairy roots,mediated by Agrobacterium rhizogenes strain K599,to validate the efficiency of a CRISPR/Cas9 system.Further optimization resulted in an efficient vector,PsU6.3-tRNA-PsPDS3-en35S-PsCas9.We used this optimized CRISPR/Cas9 system to edit the pea phytoene desaturase(PsPDS)gene,causing albinism,by Agrobacterium-mediated genetic transformation.This is the first report of successful generation of gene-edited pea plants by this route. | Guan Li Rong Liu Rongfang Xu Rajeev KVarshney Hanfeng Ding Mengwei Li Xin Yan Shuxian Huang Juan Li Dong Wang Yishan Ji Chenyu Wang Junguang He Yingfeng Luo Shenghan Gao Pengcheng Wei Xuxiao Zong Tao Yang | 2023 | The Crop Journal2023，11，1： | 0 |
