Objective: The purpose is to explore the method and clinical effects of total nasal reconstruction with the assistance of three-dimensional (3D) scanning, 3D printing and monitoring the blood circulation after operation. Methods: 3D scanning: Artex Eva 3D scanner was used to record the nose data of 500 volunteers from Xuzhou Medical University and its affiliated hospital from September 2016 to February 2017. A nose database of normal individuals was established, of which male was 138 and female was 362. In addition, 3D facial scanning was performed in patients wish to total nasal reconstruction. 3D printing: The individualized nasal structure was designed, with the assistant of patients′facial characteristics, combined with the normal nose database and the opinion of the patients. Anactual nose model was used as guidance during the operation. Postoperative monitoring: The blood flow and the retraction rate of forehead flap after surgery were measured using Laser Doppler Flowmeter and Geomagic Qualify software. The blood flow values, the temperature and the surface area of the flap were recorded and analyzed. Results: The nasal database of normal people in the Huaihai region successfully established. Overall, the width of the nose takes up a quarter of the width of the faces, and the length is 1/3 of the distance from the hairline to the chin. From February 2017 to June 2018, 7 cases underwent total nasal reconstruction operations were performed by this procedure. The nasal models were all successfully printed out, as the guide of flap taken during the operation. The mean operation time of the cases was (2.45±0.75) h, and the follow-up time was 5-15 months, with an average of 12.5 months. After the operations, the retraction rate of the forehead flap were (21.8±2.72)% in one month, and (29.1±1.82)% in six months. All patients are satisfied with the nasal appearance. Conclusions Nasal reconstruction with forehead flap based on 3D scanning and 3D printing, provides objective targets for nasal fine-structure in a noninvasive way. The postoperative monitoring of the blood flow promotes the successful completion of the total nose reconstruction.

Results There was no statistically significant differences between the postoperative actual data and the preoperative personalized data (P> 0.05) in right root wing distance, left root wing distance, nose length, nasal base width, nose width, right side vertical bisect nasal line, left side vertical bisect nasal line, nose height, medial malleolus spacing, face width, mouth split width, facial height, nasal width index, nasal width index, interondylar-nasal width index and nasal high index. The actual data of nasal deep was statistically different from preoperative personalized data (P < 0.05). Conclusions Analysis showed no significant difference between the actual data nasal surgery and preoperative customization data. 3D measurement of normal human external nasal establishment database to customize the external nose for patients with nasal defects, can assist the surgeon to perform total nasal reconstruction surgery and improve predictability and make surgery more precise. Postoperative assessments can also be performed to compare preoperative and postoperative outcomes.

Glycolysis plays an important role in the development and progression of liver diseases and shows varying degrees of enhancement in different liver diseases, and it is closely associated with mitochondrial dysfunction (oxidative phosphorylation deficiency and reactive oxygen species production), which helps to fill energy production deficiency caused by impaired oxidative phosphorylation. Therefore, it might be possible to search for potential new therapies for liver diseases through targeted regulation of the key factors in aerobic glycolysis, such as hexokinase 2, pyruvate kinase M2, and other regulatory pathways. From the perspective of the association between glycolysis and liver diseases, this article elaborates on the therapeutic significance and potential value of glycolysis in liver diseases, in order to provide new ideas for the diagnosis and treatment of liver diseases.

Inflammation is closely associated with the development of cancer. Tumor-associated macrophages (TAM) actively participate in tumor-related inflammation and promote tumor growth and metastasis, while under certain conditions, TAM also show cytotoxicity and tumor killing activity and thus inhibit the progression of cancer. Crosstalk between TAM and neighboring cells is closely associated with the progression of hepatocellular carcinoma (HCC) and drug resistance during treatment. This article summarizes the role of macrophages in HCC and the crosstalk between macrophages and other cells, so as to provide new strategies for the clinical diagnosis and treatment of HCC.

Liver failure is a common end-stage liver disease syndrome in clinical practice characterized by massive necrosis of hepatocytes leading to rapid liver failure, and it is currently believed that excessive inflammation and immune response are the core mechanisms of this disease. Endogenous lipid mediators are involved in the regulation of a variety of inflammatory processes, including initiation, maintenance, and regression, and eicosanoids and pro-decomposition lipid mediators, as well as their complex metabolic pathways and transduction signals, play a key role in the regulation of these processes. This article reviews the key role of endogenous lipid mediators in the pathophysiological mechanism of inflammation and immune dysfunction in liver failure and the potential significance and new therapeutic opportunities of lipid immune pathway in liver failure, in order to provide new ideas for the clinical diagnosis and treatment of liver failure.
