由浙江、江苏、安徽和上海组成的长三角地区是国内经济发展高地，同时也是高碳排放区域。研究长三角地区细分行业碳效率特征及其影响因素，不仅对这一地区实现低碳发展目标具有重要意义，也对全国其他地区未来低碳发展具有较为重要的指导意义。利用固定效应随机前沿模型对2014至2019年三省一市37个行业进行了碳效率测算，并对各地区工业碳效率动态变化进行了分析；然后，基于随机前沿模型方法对碳效率影响因素进行了探究；最后，应用不同生产函数形式和去极端值的方式验证了本模型的稳健性。研究结果表明，长三角地区三省一市的高碳效率行业存在明显差异，且主要受行业专业化程度以及环境规制强度的影响，国有资产占比对碳效率的影响在安徽省显著。此外，提高专业化程度是持续推动碳效率水平提高的关键性因素，环境规制能快速推动部分行业提高碳效率，但是无法推动地区工业碳效率的长期进步。

Aiming at the problem of low face recognition accuracy caused by poor image quality and loss of detailed information of face pictures obtained in security surveillance scene, this paper proposed a low-resolution face recognition algorithm based on super-resolution reconstruction. The algorithm included two sub-networks: super-resolution reconstruction and face recognition, which could respectively realize super-resolution reconstruction of low-resolution face image and extraction of face features . Firstly, the algorithm increased the number of feature maps before the activation function of super-resolution reconstru ction sub-network to achieve wide activation and ensure effective transfer of information flow, so as to reconstru ct high-resolution images containing more effective detailed information. Then, it combined image content loss and identity loss during training to retain more identity information while reconstructing image, which could make extracted face features more discriminative. Experimental results show that the proposed algorithm improves accuracy of low-resolution face recognition and has better performance than traditional algorithms on surveillance face dataset QMUL-SurFace.

Objective Explore the clinical efficacy of negative pressure wound therapy combined with hyperbaric oxygen therapy for diabetic foot. Methods From February 2013 to December 2017, the clinical data of 46 patients with diabetic foot were retrospectively analyzed. All patients were divided into control group (24 patients) and combined treatment group (22 patients) according to the treatment method. According to Wagner grade, the wounds of diabetic foot were classified as 3 to 5 grades, a total of 46 feet. The treatment method such as blood glucose control, anti-infection, debridement of wounds and wet-wrap dressings were performed in the control group. The dressing change, skin grafting or amputation was conducted according to the situation of wounds. The negative pressure wound therapy combined with hyperbaric oxygen therapy on the basis of treatment methods of control group were performed in the combined treatment group. The dressing change, skin grafting, vacuum sealing drainage or amputation was conducted according to the wounds. The wound healing, length of hospital stay and amputation after treatment were observed. Results The total effective rate of combined treatment group (59%) was significantly higher than that of the control group (33%). The length of hospital stay were (25.2±16.5) days in the control group and (28.7±12.8) days in the combined treatment group. There were 11 toe amputations in 9 patients in the control group, including 7 cases of thigh amputations and 1 case of calf amputation. There were 8 toe amputations in 5 patients, including 2 cases of calf amputation. Compared with the control group, the amputation rate was significantly decreased (z = -2.617, P<0.05) and the rate of amputation above the ankle was significantly reduced (33% vs 9%, P<0.05). Conclusion The negative pressure wound therapy combined with hyperbaric oxygen therapy for diabetic foot can significantly reduce the amputation rate and improve the quality of life for patients after discharge.

Objective To compare the safety and reliability of laminated film nickel-titanium alloy stent tube( LFNTST) and modified colon sac tube( MCST) for mediate stage repair of colorectal perforation in Tibet miniature pigs. Methods Colorectal perforationmodels of Tibet miniature pigs were established, and then they were randomly divided into the LFNTST group and MCST group. On the 7 th, 14 th, and 21 st days after procedure, the healing of the perforation was evaluated by examining thebursting pressure( BP) and hydroxyprolinecontent( HC) at site of the anastomosis. Results On the 7 th, 14 th and 21 st days of treatment, the BP was( 27. 21 ± 0. 98), ( 35. 77 ± 0. 72), and( 38. 13 ± 0. 92) Kpa, respectively, in the LF-NTST group, versus( 26. 83 ± 0. 91), ( 35. 23 ± 0. 55), and( 37. 20 ± 0. 95) Kpa, respectively, in theM CST group. The BP in the FR-NTST group and MCST group gradually increased over the treatment time( both P < 0. 05). On the 7 th, 14 th and 21 st days of treatment, the HC of colonic perforation healing site was( 22. 40 ± 0. 83), ( 25. 64 ±0. 41), and( 26. 83 ± 1. 26) μmol/g, respectively, in the LF-NTST group, versus( 22. 37 ± 0. 70), ( 25. 69 ± 0. 42), and( 26. 78 ± 1. 24) μmol/g, respectively, in the MCST group. The HC in the colonic perforation healing site of LF-NTST group and MCST group increased gradually with the treatment time( all P < 0. 05). There were no significant differences in BP or HC between the LF-NTST group and MCST group on the 7 th, 14 th and 21 st days of treatment( both P > 0. 05).Conclusion Both LF-NTST and MCST can effectively repair colorectal perforation.

Objective To research the location, composition, zoning, flow and combination form of medical system of Model 920 hospital ship, and to provide theoretical support for the design of the hospital ship. Methods The layout of medical system of the hospital ship was constructed based on the theories of ship engineering design, hospital architecture design and naval health service as well as the requirements for height and internal environment of medical system. Results The mode combining multi corridor and single column was used to design 8 operating rooms and accessories in the midship of No.01 deck. Conclusion The multi-corridor single-column combination operating area occupies less ship space resources and the surgical treatment of wounded and sick patients is efficient, which is suitable for the platform of the ship and is worthy of reference for the design of the medical system of the large-scale rescue platform on the sea.

Objective To assess the efficacy of ultrasound (US)-guided percutaneous bipolar radiofrequency ablation (BRFA) of benign thyroid nodules. Methods 33 patients were treated by BRFA. The size and blood flow signals on B-mode and contrast-enhanced US were compared before and after treatment. Complications and thyroid function were assessed at the end of BRFA and during follow-up. Results BRFA was completed in all patients without severe complications. Contrast-enhanced US showed no residual contrast enhancement with 100% complete ablation rate. Three patients experienced temporary nerve palsy with recovery within twenty minutes after suspending BRFA. One patient bled slightly after BRFA with resolution after a week. Six months after BRFA, all nodules had 50% or more volume reduction with greater than 90% volume reduction in 9.09% (3/33) of the nodules. Conclusion US-guided BRFA is effective and safe treatment of benign thyroid nodules. [ABSTRACT FROM AUTHOR]
