A 71-year-old male presented with esophageal cancer and severe aortic valve regurgitation. Treatment strategies for such patients are controversial. Considering the risks of cardiopulmonary bypass and potential esophageal cancer metastasis, we successfully performed transcatheter aortic valve implantation and minimally invasive three-incision thoracolaparoscopy combined with radical resection of esophageal cancer (McKeown) simultaneously in the elderly patient who did not require neoadjuvant treatment. This dual minimally invasive procedure took 6 hours and the patient recovered smoothly without any surgical complications.

The pathogenesis of diabetic cardiomyopathy(DCM)is complex.Autophagy plays a pivotal role in the development of DCM,and whether its level is stable or not is closely related to the development of the course of DCM.Numerous active components found in traditional Chinese medicines and compound formulations have demonstrated the ability to modulate autophagy levels.These interventions occur through various mechanisms,such as hypoglycemic,anti-apoptotic,anti-inflammatory,and anti-oxidative stress pathways.By mitigating autophagy-induced myocardial damage,enhancing cardiac function,and slowing the progression of DCM,these compounds offer promising avenues for DCM management.This paper aims to consolidate and present research findings from the last 5 years.Our goal is to provide valuable insights and references for the research,development,and clinical application of Chinese medicine in the context of combating DCM.

Objectives:
Fructosamine correlates well with glycated haemoglobin (HbA1c) in Caucasians. This study investigates this correlation and whether fructosamine can reliably estimate glycated haemoglobin in Southeast Asians.
Methodology:
We recruited 193 participants based on 4 HbA1c bands (<6.0%; 6.0 – 7.9%; 8.0– 9.9%; ≥10%) from a secondary hospital in Singapore between August 2017 and December 2021. Blood samples for fructosamine, glycated haemoglobin, albumin, haemoglobin, thyroid stimulating hormone and creatinine were drawn in a single setting for all participants. Scatter plot was used to explore correlation between fructosamine and glycated haemoglobin. Strength of linear correlation was reported using Pearson’s correlation coefficient. Simple linear regression was used to examine the relationship between fructosamine and glycated haemoglobin.
Results:
We performed simple linear regression to study the relationship between fructosamine and HbA1c in the research participants (R2 = 0.756, p<0.01). Further analysis with natural logarithmic transformation of fructosamine demonstrated a stronger correlation between HbA1c and fructosamine (R2 = 0.792, p<0.01).
Conclusions
Fructosamine is reliably correlated with HbA1c for the monitoring of glycaemic control in Southeast Asians.

Endo-beta-N-acetylglucosaminidase (ENGase) is widely distributed in various organisms. The first reported ENGase activity was detected in Diplococcus pneumoniae in 1971. The protein (Endo D) was purified and its peptide sequence was determined in 1974. Three ENGases (Endo F1-F3) were discovered in Flavobacterium meningosepticum from 1982 to 1993. After that, the activity was detected from different species of bacteria, yeast, fungal, plant, mice, human, etc. Multiple ENGases were detected in some species, such as Arabidopsis thaliana and Trichoderma atroviride. The first preliminary crystallographic analysis of ENGase was conducted in 1994. But to date, only a few ENGases structures have been obtained, and the structure of human ENGase is still missing. The currently identified ENGases were distributed in the GH18 or GH85 families in Carbohydrate-Active enZyme (CAZy) database. GH18 ENGase only has hydrolytic activity, but GH85 ENGase has both hydrolytic and transglycosylation activity. Although ENGases of the two families have similar (β/α)8-TIM barrel structures, the active sites are slightly different. ENGase is an effective tool for glycan detection andglycan editing. Biochemically, ENGase can specifically hydrolyze β‑1,4 glycosidic bond between the twoN-acetylglucosamines (GlcNAc) on core pentasaccharide presented on glycopeptides and/or glycoproteins. Different ENGases may have different substrate specificity. The hydrolysis products are oligosaccharide chains and a GlcNAc or glycopeptides or glycoproteins with a GlcNAc. Conditionally, it can use the two products to produce a new glycopeptides or glycoprotein. Although ENGase is a common presentation in cell, its biological function remains unclear. Accumulated evidences demonstrated that ENGase is a none essential gene for living and a key regulator for differentiation. No ENGase gene was detected in the genomes of Saccharomyces cerevisiae and three other yeast species. Its expression was extremely low in lung. As glycoproteins are not produced by prokaryotic cells, a role for nutrition and/or microbial-host interaction was predicted for bacterium produced enzymes. In the embryonic lethality phenotype of the Ngly1-deficient mice can be partially rescued by Engase knockout, suggesting down regulation of Engase might be a solution for stress induced adaptation. Potential impacts of ENGase regulation on health and disease were presented. Rabeprazole, a drug used for stomach pain as a proton inhibitor, was identified as an inhibitor for ENGase. ENGases have been applied in vitro to produce antibodies with a designated glycan. The two step reactions were achieved by a pair of ENGase dominated for hydrolysis of substrate glycoprotein and synthesis of new glycoprotein with a free glycan of designed structure, respectively. In addition, ENGase was also been used in cell surface glycan editing. New application scenarios and new detection methods for glycobiological engineering are quickly opened up by the two functions of ENGase, especially in antibody remodeling and antibody drug conjugates. The discovery, distribution, structure property, enzymatic characteristics and recent researches in topical model organisms of ENGase were reviewed in this paper. Possible biological functions and mechanisms of ENGase, including differentiation, digestion of glycoproteins for nutrition and stress responding were hypothesised. In addition, the role of ENGase in glycan editing and synthetic biology was discussed. We hope this paper may provide insights for ENGase research and lay a solid foundation for applied and translational glycomics.

Protein as the allergens could lead to allergy. In addition, a widespread class of allergens were known as glycans of N-glycoprotein. N-glycoprotein contained oligosaccharide linked by covalent bonds with protein. Recently,studies implicated that allergy was associated with glycans of heterologous N-glycoprotein found in food, inhalants, insect toxins, etc. The N-glycan structure of N-glycoprotein allergen has exerted an influence on the binding between allergens and IgE, while the recognition and presentation of allergens by antigen-presenting cells (APCs) were also affected. Some researches showed thatN-glycan structure of allergen was remodeled by N-glycosidase, such as cFase I, gpcXylase, as binding of allergen and IgE partly decreased. Thus, allergic problems caused by N-glycoproteins could potentially be solved by modifying or altering the structure ofN-glycoprotein allergens, addressing the root of the issue. Mechanism of N-glycans associated allergy could also be elaborated through glycosylation enzymes, alterations of host glycosylation. This article hopes to provide a separate insight for glycoimmunology perspective, and an alternative strategy for clinical prevention or therapy of allergic diseases.

Objective:To investigate the efficacy and safety of nerve decompression surgery through the lateral-rectus approach for sacral plexus nerve injury after sacral fracture fixation.Methods:A retrospective study was conducted to analyze the 10 patients with combined sacral plexus nerve injury after sacral fracture fixation who had been admitted to Department of Orthopedics, Xiangya Hospital between May 2022 and May 2023. There were 2 males and 8 females with an age of 16.5 (15.0, 26.3) years. At the time of injury, the patients had been clearly diagnosed as sacral fracture combined with sacral plexus nerve injury. By the Denis classification of sacral fractures: 7 cases of type Ⅱ and 3 cases of type Ⅲ; sacral plexus nerve injury sites: 1 case of L 4, 8 cases of L 5, 7 cases of S 1, and 2 cases of S 2. All of them were treated with reduction and internal fixation via the posterior approach within 2 weeks after injury, but after surgery their manifestations of sacral plexus nerve injury still persisted which were confirmed by CT, magnetic resonance imaging and neuromuscular electromyography. Therefore, at (4.0±2.3) months after internal fixation, all patients were treated with nerve decompression surgery through the lateral-rectus approach. The operative time, intraoperative bleeding, length of hospitalization, Gibbons nerve damage score and neurological recovery at the last follow-up were recorded. Results:In the 10 patients, the operative time was (112.0±21.5) min, intraoperative bleeding (215.0±91.3) mL, and length of hospitalization 7.0 (6.0, 8.5) d. Intraoperatively, sacral plexus nerve compression was found in 9 cases (6 cases of nerve compression and pulling due to fracture displacement, 3 cases of nerve entrapment due to soft tissue scar adhesion), and 1 case of nerve root avulsion injury. No other intraoperative complications occurred. The 10 patients were followed up for (9.2±2.3) months after surgery. At the last follow-up, the Gibbons score for the 10 patients improved from preoperative 3.0 (3.0, 3.3) points to 1.0 (1.0, 2.0) point, and their British Medical Research Council (BMRC) nerve injury grading was improved from the preoperative grade 0.0 (0.0, 1.3) to grade 3.5 (2.8, 4.0) (1 case of M5, 4 cases of M4, 4 cases of M3, and 1 case of M2).Conclusion:The lateral-rectus approach is effective and safe for exploration and decompression of the sacral plexus nerve in patients combined with sacral plexus nerve injury despite sacral fracture fixation.
