Objective:To explore the value of tailor-tack technology in vertical mastopexy and to evaluate the clinical effect of vertical mastopexy in correcting breast ptosis.Methods:From April 2010 to August 2020, 47 women aged 18 to 51 years took part in the study, and the tailor-tack technology was used to ensure the amount of redundant skin removal. The patients' degree of ptosis was moderate or severe, and the average age was 38.2 years.Results:All the cases had their drainage tube removed 2-3 days after surgery and the wound stitches removed 12-14 days after surgery. All patients had tight and full breasts after surgery. Patients were satisfied with their new breast shapes. After surgery, no patients showed early complications such as necrosis of nipple-areola complex or skin, poor wound healing or abnormal nipple sensation. Follow-up lasted for 6 months to 5 years, and there were no long-term complications such as recurrence of breast ptosis, poor nipple shape, scar flatten and enlargement.Conclusions:Tailor-Tack technology is useful in vertical mastopexy. It can be helpful to evaluate the amount of skin removal, effectively avoiding the situation of insufficient or excessive skin removal. Therefore, this is a desirable clinical skill in mastopexy.

BACKGROUND@#As a contour-supporting material, the cartilage has a significant application value in plastic surgery.Since the development of hydrogel scaffolds with sufficient biomechanical strength and high biocompatibility, cell-laden hydrogels have been widely studied for application in cartilage bioengineering. This systematic review summarizes the latest research on engineered cartilage constructed using cell-laden hydrogel scaffolds in plastic surgery. @*METHODS@#A systematic review was performed by searching the PubMed and Web of Science databases using selected keywords and Medical Subject Headings search terms. @*RESULTS@#Forty-two studies were identified based on the search criteria. After full-text screening for inclusion and exclusion criteria, 18 studies were included. Data collected from each study included culturing form, seed cell types and sources, concentration of cells and gels, scaffold materials and bio-printing structures, and biomechanical properties of cartilage constructs. These cell-laden hydrogel scaffolds were reported to show some feasibility of cartilage engineering, including better cell proliferation, enhanced deposition of glycosaminoglycans and collagen type II in the extracellular matrix, and better biomechanical properties close to the natural state. @*CONCLUSION@#Cell-laden hydrogels have been widely used in cartilage bioengineering research. Through 3-dimensional (3D) printing, the cell-laden hydrogel can form a bionic contour structure. Extracellular matrix expression was observed in vivo and in vitro, and the elastic modulus was reported to be similar to that of natural cartilage. The future direction of cartilage tissue engineering in plastic surgery involves the use of novel hydrogel materials and more advanced 3D printing technology combined with biochemistry and biomechanical stimulation.

Objective:The present study aimed to explore the clinical value of neutrophil to lymphocyte and platelet ratio (NLPR) for acute kidney injury (AKI) in elderly patients with sepsis.Methods:This was a retrospective analysis of 360 elderly patients with sepsis or septic shock who were admitted to Intensive Care Unit (ICU) of Zhongnan Hospital of Wuhan University. They were divided into AKI and non-AKI groups based on the KDIGO-AKI criteria. The independent risk factors of AKI were identified via logistic regression analysis, and the calculation of the receiver-operating characteristic (ROC) curves were used to evaluate the diagnostic capability of NLPR for AKI and the short-term outcome of sepsis patients.Results:Total of 195 (54.2%) patients were attributed to the AKI group, while 165 (45.8%) patients were allocated to the non-AKI group. The median of NLPR was significantly higher in the AKI group compared with the non-AKI group ( Z=8.640, P<0.001). Compared with the non-AKI group, the in-hospital death and the length of ICU stay increased (all P<0.05). Patients with AKI required more vasoactive drugs, mechanical ventilation, and renal replacement therapy (all P<0.05). After adjusting the demographic and clinical variables, multivariate logistic regression analysis showed that NLPR was an independent risk factor of AKI ( OR=1.016, 95% CI 1.002-1.030, P=0.027). The ROC curves showed the excellent clinical value of NLPR and which was significantly higher than the neutrophil to lymphocyte ratio (NLR) and serum creatinine. In addition, the present study revealed that the NLPR was also positively correlated with the stage of AKI ( r=0.525, P<0.001). Conclusions:The NLPR is derived from a complete blood cell count, as a new comprehensive inflammatory parameter that is simple and easily available, it is an independent risk factor for AKI in elderly sepsis patients, and should be paid attention in the clinical practice.
