The incidence rate of pancreatic neuroendocrine neoplasms （pNENs） has increased rapidly in recent years. However, the clinicopathological characteristics of pNENs are poorly understood. Medical records of patients who underwent surgery and were confirmed as pNENs by pathological examination from January 2003 to February 2015 in Qilu Hospital were reviewed retrospectively. A total of 100 patients, 36 males and 64 females, were included with a mean operation age of 46.26 ± 13.41 years. Among the 100 cases, 76 had insulinomas and 24 had non-functional pNENs. Tumor size ranged from 0.5 cm to 9 cm, and the mean size was 2.20 ± 1.40 cm. The percentages of TNM stages I, II, III, and IV tumors were 89.0%, 8.0%, 0.0%, and 3.0%, respectively. Based on the WHO classification, pNENs were classified into three grades： G1, G2, and G3. G1, G2, and G3 tumors were confirmed in 72.9%, 23.7%, and 3.4% patients, respectively. The positive rates of CgA and Syn immunohisto- chemical staining were 94.5% （69/73） and 100% （74/74）, respectively. Compared with insulinoma, non-functional pNENs have larger tumor sizes, more advanced TNM staging, a higher Ki-67 index, and a higher rate of liver metastasis （P 〈 0.05）. In conclusion, pNENs are heterogeneous tumors with varying clinical manifestations, diverse tumor biological characteristics, and different prognoses. Non-functional pNENs present a more aggressive behavioral model and have poorer prognosis than functional pNENs.

近年来,对于局部早期、无转移的胃上部癌,近端胃切除术被认为是一种保留胃功能、提高术后生活质量的手术方式。相较于全胃切除术,近端胃切除术在减轻体重、改善营养状态方面具有显著优势。然而,由于术后易发生反流性食管炎和吻合口狭窄... 详细信息

近年来,对于局部早期、无转移的胃上部癌,近端胃切除术被认为是一种保留胃功能、提高术后生活质量的手术方式。相较于全胃切除术,近端胃切除术在减轻体重、改善营养状态方面具有显著优势。然而,由于术后易发生反流性食管炎和吻合口狭窄等并发症,如何在术后进行胃食管结合部的有效重建,既保留胃功能又降低并发症的发生率,成为当前研究的热点。本文梳理并总结了胃食管结合部解基础及近端胃切除术后消化道重建方式的研究进展,并探讨了不同重建方式的优缺点和在临床应用中的效果,旨在为临床医师提供参考,以期提高近端胃切除术后患者的预后和生活质量。

Because DC conductivities of oil-paper materials can be easily affected by electric field and temperature,the electrical properties under electro-thermal coupling of oil-paper materials should be considered when optimising the insulation structure of valve-side winding of the converter *** on the finite element multi-physical field coupling simulation,the multi-objective optimisation of main insulation structure of valve-side winding is carried *** view of the high time consuming of multi-physical field calculation and the actual needs of an insulation structure optimisation,the Kriging method and technique for order preference by similarity to the ideal solution(TOPSIS)method are introduced,and combines them with NSGA-II to obtain a joint algorithm that can be used for the optimisation of insulation structure of the converter *** using the joint algorithm of multi-objective optimisation,the insulation structure configuration scheme of valve-side winding is *** can be seen from the experiment result that,on the one hand,the joint algorithm adopted can obtain the insulation structure configuration scheme that meets the design *** the other hand,when facing the configuration scheme optimisation under multi-field coupling,the computational time required by this method is only 0.15%of that required by original genetic algorithm.

A novel photo-catalytic system composed of N-doped biochars(NBCs),MnFe_(2)O_(4) and sulfite activation under ultraviolet(NBCs/MnFe_(2)O_(4)/sulfite/UV)was constructed to realize the efficient eliminate of tetracycline(TC).As the carrier of MnFe_(2)O_(4),NBCs were synthesized from alfalfa,which has large specific surface area,graphite like structure and hierarchical porous *** adsorption isotherm indicated that NBCs/MnFe_(2)O_(4)-2:1 had the best adsorption performance for TC(347.56 mg g^(-1)).Through synergistic adsorption and photocatalysis,the removal rate of TC reached 84%,which was significantly higher than that of MnFe_(2)O_(4).Electrochemical impedance spectroscopy(EIS)and Photoluminescence(PL)characterization results showed that the introduction of NBCs improved the separation efficiency of photogenerated electron and hole pairs and enhanced the photocatalytic ***,the adsorption,degradation mechanism and degradation path of TC by the catalyst were systematically analyzed by coupling HPLC–MS measurement with the theoretical *** the advantages of excellent degradation performance,low cost,easy separation and environmental friendliness of NBCs/MnFe_(2)O_(4),this work was expected to provide a new path for the practical application of biochar.
