High concentrations of copper ions(Cu(Ⅱ)) in water will pose health risks to humans and the ecological environment. Therefore, this study aims to utilize ultrasonic-cured modified municipal solid waste incineration(MSWI) fly ash for Cu(Ⅱ) adsorption to achieve the purpose of “treating waste by waste.” The effects of p H, adsorption time, initial concentration, and temperature on the modified MSWI fly ash’s adsorption efficiency were systematically studied in this article. The adsorption performance of the modified MSWI fly ash can be enhanced by the ultrasonic modification. At pH = 2, 3 and 4, the adsorption capacity of the modified MSWI fly ash for Cu(Ⅱ) increased by 2.7, 1.9 and 1.2 times, respectively. Furthermore, it was suggested that the adsorption process of the modified MSWI fly ash can be better simulated by the pseudo-second-order kinetic model, with a maximum adsorption capacity calculated by the Langmuir model of 24.196 mg.g-1. Additionally, the adsorption process is spontaneous,endothermic, and chemisorption-dominated from the thermodynamic studies(ΔH and ΔS > 0, ΔG < 0).Finally, the enhanced adsorption performance of the modified MSWI fly ash for Cu(Ⅱ) may be attributed to electrostatic interaction and chelation effects.

Under the only assumption of the cone property for a given domain Ω?R n, it is proved that interpolation inequalities for intermediate derivatives of functions in the Sobolev spaces Wm,p (Ω) or even in some weighted Sobolve spaces W w m,p (Ω) still hold. That is, the usual additional restrictions that Ω is bounded or has the uniform cone property are both removed. The main tools used are polynomial inequalities, by which it is also obtained pointwise version interpolation inequalities for smooth and analytic functions. Such pointwise version inequalities give explicit decay estimates for derivatives at infinity in unbounded domains which have the cone property. As an application of the decay estimates, a previous result on radial basis function approximation of smooth functions is extended to the derivative-simultaneous approximation.

Purpose: To assess the long time follow-up nerve function and clinical value of great auricular nerve grafting in the treatment of facial palsy after parotidectomy。Methods: Fourteen patients with parotid tumors who were treated with great auricular nerve grafting after parotidectomy were followed up from 1998 to 2004 ( 9 males and 5 females; age range 22-65 years)。Four were benign and ten were malignant tumors。All of them were unilateral affected。Eleven cases of nerve grafting were done immediately after the tumor dissection。Two cases were done 6 months after tumor surgery and one case was 9 months。Six cases were affected in the facial nerve main trunk, four cases in the cervical division, one in the zygomatic branch and one in the zygomatic and temporal branch。The great auricular nerve in the same side of the tumor was harvested for nerve grafting except for both sides were used in one case。These patients were followed up from half a year to 5 years, until they were recovered or no obvious recovery was observed in half a year。Neurotrophic drugs and neuromuscular facial retraining were both given after operation。House-Brackmann grading scale, electroneurography were applied to evaluate the results。Results: Ten cases which were treated at the same time with tumor dissection recovered to HB gradeⅠtoⅡexcept for one patient recurred one year after operation All 10 patients were satisfied with the results。7 cases suffered from synkinesis in the tumor side。2 patients had no recovery in lifting eyebrow。

The valorisation of vegetable by-products is a promising strategy to combat climate change and achieve global carbon neutrality goals. This study aimed to exploit the high-value utilization of garlic by-products and to investigate the antihypertensive effects and potential mechanisms of the resulting angiotensin-converting enzyme （ACE）1inhibitory peptides. After protein extraction， enzymatic hydrolysis， and activity-directed fractionation， a potent and highly stable ACE inhibitory peptide (IC50value: 31.38 μmol/L) was obtained， which was identified as VWAS and acted as a competitive inhibitor. VWAS stably bound to key residues in the ACE active center mainly through hydrogen bonding interactions and effectively lowered blood pressure in spontaneously hypertensive rats via alleviating renal and cardiac injuries， improving endothelial dysfunction， and regulating the renal renin-angiotensin system， antioxidant system， and anti-inflammatory system. These findings suggested that garlic protein-derived peptide （VWAS） was a desirable candidate for antihypertensive functional foods and provided guidance for the high-value utilization of garlic by-products.

目的建立一种用于研究垂直骨增量植骨材料的大鼠动物模型。方法选取12只320g雄性SD大鼠作为实验动物。翻瓣,去除骨膜,使用环形取骨钻在大鼠颅骨制备环形骨裂隙,放置钛壳。通过中央小孔填充脱单白牛骨基质并用膨体型聚四氟乙烯膜封闭小孔标记为支架组(n=12)。只接受空钛壳的大鼠标记为空白组(n=12)。12周后安乐死大鼠,取材,对样本进行Micro-CT和组织学分析检查。结果仅3只大鼠出现局部软组织坏死,钛壳脱落现象。其余钛壳均固位在大鼠颅骨。HE染色观察,骨组织样本无炎性反应,支架组和空白组均有新骨生成。Micro-CT数据分析显示支架组的新骨体积优于空白组(分别为41.05%±5.04%、22.75%±5.77%,P=0.000)。组织形态学测量显示支架组的垂直骨高度略高于空白组(分别为2.27±0.31mm、1.86±0.20mm,P=0.002)。结论此模型能客观地反映植骨材料的垂直成骨潜力,为用于垂直骨增量植骨材料的相关研究提供参照。
