Purpose:
This study was performed to investigate influencing factors of preoperative muscle mass-to-fat ratio (MMFR) and its impact on overall survival and postoperative complications of colon cancer.
Methods:
Patients who underwent colectomy for stage I–III colon cancer at the Second Affiliated Hospital of Soochow University between January 2016 and December 2022 were included. The skeletal muscle and fat area at the third lumbar vertebra were measured with preoperative CT measurement. MMFR was defined as the ratio of skeletal muscle area to total fat area, and low MMFR was defined as the 2 lowest tertiles (≤0.585). Univariate and multivariable analyses were conducted to assess the impact of MMFR on overall complications and survival outcomes. Kaplan-Meier survival curves and log-rank test were used to compare the overall survival between high MMFR and low MMFR groups.
Results:
A total of 885 patients were analyzed. Female sex, older age, high body mass index, sarcopenia, and high cancer stage were more likely to result in low MMFR. Complications, including intestinal fistula, chylous fistula and organ space surgical site infection were significantly higher in the low MMFR group. Low MMFR was an independent factor associated with overall complications (odds ratio, 1.940; 95% confidence interval [CI], 1.252–3.007; P < 0.01) and long-term survival (hazard ratio, 2.222; 95% CI, 1.443–3.425; P < 0.01). Furthermore, patients with high MMFR had a higher survival rate than patients with low MMFR (P < 0.01).
Conclusion
Low MMFR is an independent factor that predicts worse overall survival and complications in patients with colon cancer.

Objective To evaluate the role of autophagy in cerebral ischemia-reperfusion (I/R) injury in diabetic mice and the relationship with histone deacetylase 3 (HDAC3)/Bmal1 signaling pathway.Methods Healthy clean-grade male C57BL/6 mice were used in the study.Diabetes mellitus was induced by intraperitoneal injection of streptozotocin.Thirty-six mice with diabetes mellitus after being fed for 8 weeks were divided into 3 groups (n =12 each) using a random number table method:sham operation group (group S),I/R group and I/R plus HDAC3 inhibitor group (group I/R-H).Cerebral I/R was induced by middle cerebral artery occlusion for 1 h,followed by 24-h reperfusion in anesthetized mice.Specific HDAC3 inhibitor RGFP966 10 mg/kg was subcutaneously injected at 30 min before establishing the model in group I/R-H.Brain tissues were obtained at 24 h of reperfusion for microscopic examination and for determination of cerebral infarct size (by TTC),cell apoptosis (by TUNEL),activities of superoxide dismutase (SOD) and reactive oxygen species (ROS) and malondialdehyde (MDA) content (by colorimetric assay),expression of autophagy-related protein Beclin-1 and LC3B (by immunofluorescence),and expression of HDAC3,Bmal1,GSK-3β and p62 (by Western blot).Apoptosis index (AI) was calculated.Results Compared with group S,the cerebral infarct size was significantly increased,the activities of SOD and ROS and content of MDA in brain tissues were decreased,the expression of Bmal1,p-GSK-3β and HDAC3 was down-regulated,and AI was increased in group I/R (P<0.05).Compared with group I/ R,the cerebral infarct size was significantly increased,the activities of SOD and ROS and content of MDA in brain tissues were increased,the expression of Bmall,p-GSK-3β,Beclin-1 and LC3B was up-regulated,AI was decreased,and the expression of HDAC3 and p62 was down-regulated in group I/R-H (P< 0.05).Conclusion HDAC3/Bmal1 signaling pathway exerts endogenous protective effect through activating autophagy and increasing the antioxidant capacity following cerebral I/R in diabetic mice.

With the requirements of early diagnosis, biomarker development and functional definition, the challenge of sensitivity of immunoassay has become increasingly prominent. How to improve it to break the bottleneck has become a major challenge in the field of bioassays. Amplifying the immunosignal is the most direct method to improve detection sensitivity. Biotin-avidin system (BAS), tyramide signal amplification (TSA) and immuno-polymerase chain reaction (Im-PCR) are the most classic signal amplification techniques which significantly improved the sensitivity of immunoassays. In recent years, studies have confirmed that the sensitivity of immunoassays can be further increased by approximately three orders of magnitude with the invention of techniques including catalyzed reporter deposition-based signal amplification, nanotechnologies-based signal amplification and hybridization chain reaction-based signal amplification. Herein, we will summarize the techniques that have been developed in recent years for amplifying the signals of immunodetection and comparatively analyze their advantages and disadvantages in order to provide reference for the developed techniques transformed to clinical application and further research on ultrasensitive immunoassays.

Aim To investigate the role of cholesterol in the regulation of lipid raft and the function of platelets.Methods Using in vitro incubation of methyl β-cyclodextrin(MβCD)and in vivo elevation of peripheral blood total cho-lesterol levels to remove and load platelet cholesterol,respectively.Cholera toxin B staining combined with flow cytometry was used to detect platelet lipid raft content,fluorescence antibody staining combined with flow cytometry was used to detect the expression levels of P-selectin and activated integrin α Ⅱ bβ3,annexin Ⅴ labeling combined with flow cytometry was used to detect the level of phospholipid efflux,in vitro experimental system and rat tail bleeding experiment were used to detect platelet aggregation ability.Results The content of lipid raft on B lymphocytes decreased with the removal of cholesterol,while in vitro incubation of MβCD to remove platelet cholesterol significantly increased its lipid raft level(P<0.05).Consistent with this,in vivo cholesterol loading increased the lipid raft content of B lymphocytes but decreased the lipid raft content of platelets(P<0.05).The increase in lipid raft after removing cholesterol was not conducive to platelet activation and aggregation function.In vivo cholesterol loading downregulated platelet lipid raft content(P<0.05),enhanced its ability to respond to low concentration stimulant for activation aggregation and coagulation,and this enhancing effect disappeared after cholesterol removal.Conclusion Platelet cholesterol is a key regulator of platelet lipid raft content and platelet function,which can negatively regulate lipid raft,promote platelet activation,and enhance their coagulation function.

OBJECTIVE: To study the anti-inflammatory effect and its mechanism of the extract of Dcsmodium microphyllum, so as to provide experiment reference for further study of D. microphyllum. METHODS: Acute inflammatory model was established by xylene,glacial acetic acid and carrageenan. Using dexamethasone as positive control (0.005 g/kg), inhibitory effects of intragastric different doses of the extract of D. microphyllum (50, 30, 15 g/kg) on xylene-induced ear swelling in normal mice and adrenalectomized mice, glacial acetic acid-induced permeability increasing of abdominal capillaries in normal mice, carrageenan- induced paw swelling in normal mice and adrenalectomized mice were investigated. The levels of MDA, SOD and NO in the inflammatory tissue of toes of adrenalectomized mice were detected in carrageenan-induced inflammation model. Blank group was set for control (ig. equal volumn of water). RESULTS: Compared with blank group, ear swelling degree of normal mice and adrenalectomized mice were decreased significantly in D. microphyllum extract high-dose and medium-dose groups while inhibitory rate of ear swelling was increased significantly; the permeability of abdominal capillaries of normal mice was significantly decreased in D. microphyllum extract groups; the swelling degree of toes in normal mice of D. microphyllum extract high-dose and middle-dose groups and adrenalectomized mice were significantly decreased while inhibitory rate of toe swelling was increased significantly (P<0.05 or P<0.01). The levels of MDA and NO in the toe inflammatory site of adrenalectomized mice were decreased significantly in D. microphyllum extract high-dose and medium-dose groups, while the level of SOD was increased significantly (P<0.05). CONCLUSIONS: D. microphyllum extract can inhibit acute inflammation in mice significantly. Its anti-inflammatory mechanism is associated with decreasing MDA and NO while increasing SOD levels, and the anti-inflammatory effect does not depend on the hypothalamus-pituitary-adrenal axis system.
