Background: The association of changes in metabolic syndrome (MetS) with cognitive function remains unclear. We explored this association using prospective and Mendelian randomization (MR) studies. Methods: MetS components including high-density lipoprotein cholesterol (HDL-C), systolic blood pressure (SBP), waist circumference (WC), fasting plasma glucose (FPG), and triglycerides were measured at baseline and two follow-ups, constructing a MetS index. Immediate, delayed memory recall, and cognitive function along with its dimensions were assessed by immediate 10- word recall test (IWRT) and delayed 10-word recall test (DWRT), and mini-mental state examination (MMSE), respectively, at baseline and follow-ups. Linear mixed-effect model was used. Additionally, the genome-wide association study (GWAS) of MetS was conducted and one-sample MR was performed to assess the causality between MetS and cognitive function. Results: Elevated MetS index was associated with decreasing annual change rates (decrease) in DWRT and MMSE scores, and with decreases in attention, calculation and recall dimensions. HDL-C was positively associated with an increase in DWRT scores, while SBP and FPG were negatively associated. HDL-C showed a positive association, whereas WC was negatively associated with increases in MMSE scores, including attention, calculation and recall dimensions. Interaction analysis indicated that the association of MetS index on cognitive decline was predominantly observed in low family income group. The GWAS of MetS identified some genetic variants. MR results showed a non-significant causality between MetS and decrease in DWRT, IWRT, nor MMSE scores. Conclusion Our study indicated a significant association of MetS and its components with declines in memory and cognitive function, especially in delayed memory recall.

Hepatocellular carcinoma is one of the most common malignant tumors worldwide, posing a great threat to human health and life. Despite the tremendous progress in understanding the origin and molecular characterization of hepatocellular carcinoma, there are still few therapeutic options that can significantly increase the survival rate and improve the quality of life of patients. Protein post-translational modifications (PTMs) are regulatory mechanisms for protein activity, localization, expression, and interactions with other cellular molecules that induce changes in protein properties and functions. More and more studies have demonstrated that PTMs and immunotherapy play an important role in the development of hepatocellular carcinoma, even in the immunosurveillance of hepatocellular carcinoma and the treatment and prognosis of hepatocellular carcinoma patients. Traditional types of PTMs include phosphorylation, glycosylation, methylation, and ubiquitination. Phosphorylation affects cancer development and progression by regulating tumor cell proliferation, invasion and metastasis, and inhibiting apoptosis. There are two main types of glycosylation: O-glycosylation andN-glycosylation. Abnormal glycosylation not only promotes the proliferation and metastasis of hepatocellular carcinoma cells, but also plays an important role in immune recognition and immune escape. Common methylation modifications include DNA methylation, RNA methylation and histone methylation. Among them, histone methylation, as an important epigenetic regulatory mechanism, is of great theoretical and practical significance for understanding the mechanism of hepatocellular carcinoma as well as carrying out the corresponding prevention and immunotherapy. Ubiquitination plays an important role in the localization, metabolism, function, regulation and degradation of proteins, and it is regulated at different levels by ubiquitin-activating enzyme (E1), ubiquitin-conjugating enzyme (E2), ubiquitin-conjugating enzyme (E3), and a series of deubiquitinating enzymes (DUBs) and is closely related to hepatocellular carcinoma immunotherapy. This paper begins with a brief overview of the importance of PTMs of proteins, discusses the importance of these traditional types of PTMs in hepatocellular carcinoma immunotherapy, and summarizes the most recent applications of these approaches in hepatocellular carcinoma in order to explore the mechanism of action of PTMs in hepatocellular carcinoma immunotherapy. Then, we summarize the finding that programmed death-ligand 1 (PD-L1) is associated with a variety of conventional types of PTMs, that in-depth study of the mechanisms regulating PD-L1 expression in tumor cells is expected to improve therapeutic efficacy, and that targeting PD-L1 in PTMs is expected to be a new field for exploring hepatocellular carcinoma immunotherapy in the future. Finally, we discuss the current status of research on PTMs for hepatocellular carcinoma immunotherapy and provide new insights and future research directions. In addition to the traditional types of PTMs, multiple novel PTMs have also been identified in published research reports, while the relationship between novel PTMs and hepatocellular carcinoma and the types of PTMs to other undiscovered proteins are still poorly understood, and future research will be focused on a more comprehensive knowledge and understanding of PTMs as well as on exploring new types and mechanisms of PTMs. Overall, further investigation of the role of PTMs in tumor immunity could help to discover new biomarkers and to develop more effective and personalized cancer immunotherapies and targeted therapies, expanding our understanding of cancer biology.

Purpose::Shaping and assembling contemporary external fixators rapidly for the severe mandibular fractures remains a challenge, especially in emergency circumstance. We designed a novel external fixator that incorporates universal joints to provide the stabilization for mandibular comminuted fractures. This study aims to confirm the efficacy of this novel external fixator through biomechanical tests in vitro and animal experiments. Methods::In vitro biomechanical tests were conducted using 6 fresh canine with mandibular defect to simulate critical comminuted fractures. Three mandibles were stabilized by the novel external fixator and other mandibles were fixed by 2.5 mm reconstruction plates. All fixed mandibles were subjected to loads of 350 N on the anterior regions of teeth and 550 N on the first molar of the unaffected side. The stability was evaluated based on the maximum displacement and the slope of the load-displacement curve. In animal experiments, 9 beagles with comminuted mandibular fractures were divided into 3 groups, which were treated with the novel external fixation, reconstruction plate, and dental arch bar, respectively. The general observation, the changes in animals’ weight, and the surgical duration were recorded and compared among 3 groups. The CT scans were performed at various intervals of 0 day (immediately after the surgery), 3 days, 7 days, 14 days, 21 days, and 28 days to analyze the displacement of feature points on the canine mandible and situation of fracture healing at 28 days. The statistical significance was assessed by the two-way analysis of variance test followed by the Bonferroni test, enabling multiple comparisons for all tests using GraphPad Prism10.1.0 (GraphPad Inc, USA). Results::The outcomes of the biomechanical tests indicated that no statistically significant differences were found in terms of the maximum displacement ( p = 0.496, 0.079) and the slope of load displacement curves ( p = 0.374, 0.349) under 2 load modes between the external and internal fixation groups. The animal experiment data showed that there were minor displacements of feature points between the external and internal fixation groups without statistic difference, while the arch bar group demonstrated inferior stability. The CT analysis revealed that the best fracture healing happened in the internal fixation group, followed by the external fixation and arch baring at 28 days after fixation. The external fixation group had the shortest fixation duration (25.67 ± 3.79) min compared to internal fixation ((70.67 ± 4.51) min, p < 0.001) and arch baring ((42.00 ± 3.00) min, p = 0.046). Conclusion::The conclusion of this study highlighted the efficacy and reliability of this novel external fixator in managing mandibular fractures rapidly, offering a viable option for the initial stabilization of comminuted mandibular fractures in the setting of emergency rescue.

ObjectiveProlonged storage of packed red blood cells （PRBC） is reportedly associated with poor clinical outcomes in critically ill， trauma， and cardiac surgery patients. However， the impact of PRBC’s age on long-term oncological outcomes in cancer patients remains poorly defined. Here we retrospectively evaluated the effect of PRBC’s age on overall survival and biochemical recurrence in patients undergoing curative resection of hepatocellular carcinoma. MethodsA total of 1 221 qualified patients undergoing curative hepatectomy for HCC between August 1， 2008 and June 30， 2012 at the Sun Yat-sen University Cancer Center （Guangzhou， PR China） were divided into nontransfused or transfused group. Transfused patients were further divided according to PRBC storage duration （fresh PRBC group， ≤ 14 days； old PRBC group， > 14 days）. Overall survival （OS）， intrahepatic recurrence-free survival （IRFS）， extrahepatic metastasis-free survival （EMFS） were assessed and multivariate analyses were performed to evaluate the association of PRBC storage duration with cancer outcomes. ResultsA total of 251 （20.6%） patients received intraoperative PRBC transfusion. Of these， 112 and 125 patients were grouped in the fresh and the old PRBC groups， respectively. The Kaplan–Meier curves showed that both fresh PRBC group and old PRBC group had worse OS， IRFS， and EMFS than nontransfused group （P<0.001）. Cox regression analyses further indicated that old PRBC transfusion was an independent prognostic factor of OS （HR=1.417， P=0.049）， IRFS （HR=1.519， P=0.013） for patients with HCC； conversely， new PRBC transfusion was not. ConclusionIn patients undergoing curative hepatectomy， intraoperative transfusions of PRBC that had been stored for more than 2 weeks is independently associated with a significantly increased risk of intrahepatic recurrence and reduced overall survival.

Objective To observe the effect sling exercise therapy (SET) and Tuina on radicular cervical spondylosis. Methods From August, 2015 to December, 2016, 72 patients with radicular cervical spondylosis were randomly divided into control group (n = 36) and trial group (n = 36), who accepted traction and SET+Tuina, respectively, for four weeks. They were measured F-wave conduction velocity with electromyogram from median nerve and ulnar nerve, somatosensory evoked potential (SEP), and current perception threshold (CPT) before and after treatment. The clinical ratio of improvement was calculated. Results The ratio of improvement was 83.33% in the trial group more than 58.33% in the control group (Z = 2.093, P < 0.05). F-wave conduction velocity increased in both groups after treatment (t > 12.059, P < 0.001), and increased more in the trial group than in the control group (t > 3.266, P < 0.01); while the latency of SEP decreased in N9 and N13 in both groups (t > 7.061, P < 0.001), and decreased more in the trial group than in the control group (t > 8.033, P < 0.001); the grade of CPT decreased in both groups (t > 8.895, P < 0.001), and decreased more in the trial group than in the control group (t = 8.913, P < 0.001). Conclusion The combination of SET and Tuina can promote the repair of nerve conduction of cervical spondylotic radiculopathy.
