Trimetallic mesoporous PdCuRu for efficient formate electrosynthesis from polyethylene terephthalate recycling

Science China Chemistry 2025年

作者： Yuting Li Huiqin Yao Lizhi Sun Shu Han Xiaoxiang Xu Guangyin Fan Ben Liu College of Chemistry and Materials Science Sichuan Normal University Key Laboratory of Green Chemistry and Technology of Ministry of Education College of Chemistry Sichuan University School of Basic Medical Sciences Ningxia Medical University department of Otorhinolaryngology-head and neck Surgery Zhongnan Hospital of Wuhan University

Electrochemical recycling of waste polyethylene terephthalate（PET） plastics represents a green and sustainable route to produce valuable fuels and address serious environmental issues. Despite some encouraged achievements, their progress is still slower because of the lack of highly active and selective electrocatalysts. Here, we reported an efficient PET recycling route with trimetallic PdCuRu mesoporous nanospheres（MSs） as a high-performance electrocatalyst that achieved selective electrosynthesis of valuable formate from PET hydrolysate（PETH） electrooxidation. Penetrated metal mesopores and trimetallic compositions of PdCuRu MSs synergistically optimized electronic structures of Pd sites and changed chemisorption properties of intermediates, which disclosed a high formate Faradic efficiency of 97% and impressive yield rate of 0.49 mmol h-1cm-2in an alkaline solution. Meanwhile, this electrocatalyst held good electrocatalytic stability, retaining high formate Faradic efficiency and yield rate even being performed for 10 cycles, which highlighted its potential applications for practical PET recycling. Our study provides a powerful strategy for designing high-performance electrocatalysts toward selective electro-synthesis of valuable fuels from various waste plastics.

Primary chordoma of the nose

引用

Chinese Medical Journal 2003年第1期116卷 154-156页

作者：牟忠林刘兆华 department of Otolaryngology-head and neck Surgery

Chordoma as a rare malignant tumor arising from remnants of the notochord, accounts for 4% of malignant bone tumors. It occurs twice as frequently in men compared with women and is uncommon in individuals less than 40 years of age.1-3 Topographic distribution is spheno-occipital (35% to 44%), vertebral (15%), and sacrococcygeal (42% to 50%).4 Unusual locations include the mandible and the maxilla, and lesions in these locations have been called ectopic or dental chordomas. Some chordomas with nasal and paranasal presentations have been reported, but primary chordoma of the nose occurs rarely. To our knowlege only two cases have been reported so far according to the literature.4,5 In this paper, we present primary chordoma of the nose, its characteristics and our experiences with it.

An efficient strategy for establishing a model of sensorineural deafness in rats

Neural Regeneration Research 2015年第10期10卷 1683-1689页

Ototoxic drugs can be used to produce a loss of cochlear hair cells to create animal models of deafness. However, to the best of our knowledge, there is no report on the establishment of a rat deafness model through the combined application of aminoglycosides and loop diuretics. The aim of this study was to use single or combined administration of furosemide and kanamycin sulfate to establish rat models of deafness. The rats received intravenous injections of different doses of furosemide and/or intramuscular injections of kanamycin sulfate. The auditory brainstem response was measured to determine the hearing threshold after drug application. Immunocytochemistry and confocal microscopy were performed to evaluate inner ear morphology. In the group receiving combined administration of furosemide and kanamycin, the auditory brainstem response threshold showed significant elevation 3 days after administration, higher than that produced by furosemide or kanamycin alone. The hair cells showed varying degrees of injury, from the apical turn to the basal turn of the cochlea and from the outer hair cells to the inner hair cells. The spiral ganglion cells maintained a normal morphology during the first week after the hair cells completely disappeared, and then gradually degenerated. After 2 months, the majority of spiral ganglion cells disappeared, but a few remained. These findings demonstrate that the combined administration of furosemide and kanamycin has a synergistic ototoxic effect, and that these drugs can produce hair cell loss and hearing loss in rats. These findings suggest that even in patients with severe deafness, electronic cochlear implants may partially restore hearing.

Adipose-derived mesenchymal stem cells accelerate nerve regeneration and functional recovery in a rat model of recurrent laryngeal nerve injury

引用

Neural Regeneration Research 2017年第9期12卷 1544-1550页

Medialization thyroplasty or injection laryngoplasty for unilateral vocal fold paralysis cannot restore mobility of the vocal fold. Recent studies have shown that transplantation of mesenchymal stem cells is effective in the repair of nerve injuries. This study investigated wheth- er adipose-derived stem celt transplantation could repair recurrent laryngeal nerve injury. Rat models of recurrent laryngeal nerve injury were established by crushing with micro forceps. Adipose-derived mesenchymal stem cells （ADSCs; 8 ×105） or differentiated Schwann-like adipose-derived mesenchymal stem cells （dADSCs; 8×105） or extracellular matrix were injected at the site of injury. At 2, 4 and 6 weeks post-surgery, a higher density of myelinated nerve fiber, thicker myelin sheath, improved vocal fold movement, better recovery of nerve conduction capacity and reduced thyroarytenoid muscle atrophy were found in ADSCs and dADSCs groups compared with the extracellu- lar matrix group. The effects were more pronounced in the ADSCs group than in the dADSCs group. These experimental results indicated that ADSCs transplantation could be an early interventional strategy to promote regeneration after recurrent laryngeal nerve injury.

Factors contributing to lymph node occult metastasis in supraglottic laryngeal carcinoma cT2-T4 N0M0 and metastasis predictive equation

引用

Chinese Journal of Cancer Research 2014年第6期26卷 685-691页

作者： Hongzhi Ma Meng Lian Ling Feng Pingdong Li Lizhen Hou Xiaohong Chen Zhigang Huang Jugao Fang department of Otolaryngology-head and neck Surgery Beijing Tongren Hospital Capital Medical University Key Laboratory of Otorhinolaryngology head and neck Surgery Ministry of Education Beijing Institute of Otorhinolaryngology Beijing Key Laboratory of head and neck Molecular Diagnostic Pathology

Objective： To investigate factors that contribute to lymph node metastasis（LNM） from clinical cT2-T4 N0M0（cN0） supraglottic laryngeal carcinoma（SLC）, and to predict the risk of occult metastasis before ***： A total of 121 patients who received surgery were retrospectively analyzed. Relevant factors regarding cervical LNM were analyzed. Multivariate analyses were conducted to predict the region where the metastasis occurred and prognosis. Results： The overall metastatic rate of c N0 SLC was 28.1%. Metastatic rates were 15.4%, 32.5% and 35.7% for T2, T3 and T4, respectively. Metastatic rates for SLC levels II, III and IV were 19.6%, 17.2% and 3.6%, respectively. A regression equation was formulated to predict the probability of metastasis in cN0 SLC as follows： Pn=e（–3.874＋0.749T3＋1.154T4＋1.935P1＋1.750P2）/[1＋e（–3.874＋0.749T3＋1.154T4＋1.935P1＋1.750P2）]. Approximately 0.2% of patients experienced LNM with no recurrence of laryngeal cancer. Comparison of the intergroup survival curves between patients with and without LNM indicated a statistically significant difference（P=0.029）.Conclusions： Cervical lymph node metastatic rates tended to increase in tandem with T stage in patients with LNM in cN0 SLC, and neck dissection is advised for these patients. Moreover, cervical LNM in cN0 SLC showed a sequential pattern and may be predicted.
