Objective To investigate the mechanism of Guizhi Tongluo Tablets(GZTLP)on improving atherosclerosis in APOE knockout mice by regulating neutrophil extracellular trapping nets(NETs).Methods After modeling,24 APOE knockout mice aged 8 weeks were randomly divided into 4 groups:GZTLP high-dose group,low-dose group,model control group and normal control group,with 6 mice in each group.GZTLP was given 1.87 mg·g-1 and 0.47 mg·g-1 intragastric administration in high-dose group and low-dose group,respectively.The normal control group and model control group were given 0.9%sodium chloride solution intragastric administration for 6 weeks,and the lipid plaque deposition in aorta was observed by gross oil red O staining.Lipid deposition in aortic root was observed by oil red O staining.The pathological changes of lipid plaques in aortic root were observed by HE staining.The levels of interleukin-1β(IL-1β)and tumor necrosis factor α(TNF-α)in peripheral blood of mice were detected by enzyme-linked immunosorbent assay(ELISA).The expression of lymphocyte antigen 6G(Ly6G),myeloperoxidase(MPO)and citrulinated histone(Cit-H3)in plaques of the aortic arch and the colocalization of Ly6G,MPO and Cit-H3 were detected by immunofluorescence assay.Results Compared with the normal control group,the aorta of mice in the model control group showed serious lipid plaque deposition,morphological damage,and a large number of inflammatory cells infiltration,the contents of serum inflammatory factors IL-1β and TNF-α were increased,and the protein expressions of Ly6G,Cit-H3 and MPO were significantly increased.Compared with model control group,GZTLP group reduced the amount of lipid plaque deposition in aorta,the arrangement of aortic cells was more regular,the inflammatory cell infiltration was improved,and the contents of serum inflammatory factors IL-1β and TNF-α were significantly decreased(P<0.05).The colocalization and the protein expression of Ly6G,MPO and Cit-H3 were significantly decreased in aortic tissues(P<0.01).Conclusions GZTLP can improve atherosclerosis,and its mechanism may be related to the inhibition of neutrophil extracellular trapping nets.

Objective:To establish a nomogram model for predicting the risk of sepsis in diabetic foot patients, and to provide reference for clinical prevention and treatment.Methods:The clinical data of 430 patients with diabetic foot who were hospitalized in Chu Hsien-I Memorial Hospital of Tianjin Medical University from January 2022 to March 2023 were reviewed and collected, including age, gender, past medical history, smoking and drinking history, family history, diabetes course, Texas grade of diabetic foot and laboratory indicators within 24 hours after admission. Patients were divided into sepsis group and non-sepsis group according to the presence or absence of sepsis during hospitalization. The differences in clinical data between the two groups were compared. Multivariate Logistic regression analysis was used to screen the influencing factors of sepsis in patients with diabetic foot during hospitalization, and a nomogram predictive model was established. The performance of the prediction model was evaluated by receiver operator characteristic curve (ROC curve), calibration curve and decision curve analysis (DCA). Internal validation was performed by using Bootstrap method.Results:A total of 430 patients were enrolled, among which 90 patients developed sepsis during hospitalization and 340 patients did not. There were statistically significant differences in diabetes course, Texas grade of diabetic foot, white blood cell count (WBC), neutrophil count (NEU), lymphocyte count (LYM), neutrophil to lymphocyte ratio (NLR), hemoglobin (Hb), albumin (Alb), glycosylated hemoglobin (HbA1c), C-reactive protein (CRP), and blood urea nitrogen (BUN) between the two groups. Multivariate Logistic regression analysis showed that diabetes course [odds ratio ( OR) = 2.774, 95% confidence interval (95% CI) was 1.053-7.308, P = 0.039], Texas grade of diabetic foot ( OR = 2.312, 95% CI was 1.014-5.273, P = 0.046), WBC ( OR = 1.160, 95% CI was 1.042-1.291, P = 0.007), HbA1c ( OR = 1.510, 95% CI was 1.278-1.784, P < 0.001), CRP ( OR = 1.007, 95% CI was 1.000-1.014, P = 0.036) were independent risk factors for sepsis in patients with diabetic foot during hospitalization, while Alb was a protective factor ( OR = 0.885, 95% CI was 0.805-0.972, P = 0.011). A nomogram predictive model was constructed based on the above 6 indicators. The ROC curve showed that the area under ROC curve (AUC) of the nomogram predictive model for identifying the sepsis patients was 0.919 (95% CI was 0.889-0.948). The AUC of the nomogram predictive model after internal verification was 0.918 (95% CI was 0.887-0.946). Hosmer-Lemeshow test showed χ2 = 2.978, P = 0.936, indicating that the calibration degree of the predictive model was good. Calibration curve showed that the predicted probability of sepsis was in good agreement with the actual probability. DCA curve showed that the nomogram predictive model had good clinical usefulness. Conclusion:The nomogram predictive model based on the risk factors of diabetes course, Texas grade of diabetic foot, WBC, HbA1c, CRP and Alb has good predictive value for the occurrence of sepsis in patients with diabetic foot during hospitalization, which is helpful for clinical screening of the possibility of diabetic foot patients progressing to sepsis, and timely personalized intervention for different patients.

Objective:To explore the sleep status and impact factor analysis of patients in clinical trials of antineoplastic drugs, and provide a basis for improving the sleep status and impact analysis of patients in clinical trials of antineoplastic drugs.Methods:From April to May 2023, 107 oncology patients in the Phase I Clinical Trial Ward of the Affiliated East Hospital of Tongji University were selected as the research objects by convenient sampling method. The general information questionnaire, Pittsburgh Sleep Quality Index Scale (PSQI), Numeric rating scale (NRS), Generalized Anxiety Disorder Scale (GAD-7) and Depression Self-Ration Tool Scale (PHQ-9). Multivariate Logistic regression analysis methods were used to carry out a cross-sectional investigation and the relevant factors affecting patients′sleep.Results:Totally 103 questionnaires were effectively collected. The 103 patients′ age ranged from 20 to 75 years old, including 61 males and 42 females. 47.57% (49/103) patients in clinical trials of antineoplastic drugs had abnormal sleep. The average score of patients (PSQI) (7.66 ± 3.93) was higher than the average score of the domestic norm (3.88 ± 2.52), and there was significant statistical difference ( t = 9.76, P<0.01). Logistic regression analysis showed that pain ( OR = 3.004, 95% CI 1.135-7.948, P<0.05) and trial cycle ( OR = 0.432, 95% CI 0.191-0.978, P<0.05) were significant risk factors for abnormal sleep quality. Conclusions:The incidence of abnormal sleep quality in patients of clinical trials of antineoplastic drugs is high, but the sleep quality is poor. The factors that affect the sleep quality of patients in clinical trials of antineoplastic drugs are mainly related to the patient′s trial cycle and cancer pain. According to these characteristics, individualized programs should be developed to improve the sleep quality of patients with advanced cancer, so as to improve the quality of life of patients with advanced cancer.

Osteoporosis （OP） is a systemic metabolic bone disease. Amid population aging， OP has become a major health problem for the middle-aged and the elderly in China. Aging， iron load， and estrogen deficiency break the balance between oxidation and antioxidant systems， and the increase of reactive oxygen species mediates oxidative stress to damage DNA， lipids， proteins and other macromolecules， thus accelerating cell apoptosis and inducing OP， obesity， and neurodegenerative disorders. It has been found that oxidative stress is of great significance in the pathogenesis of OP. Oxidative stress regulates the signaling pathways， cytokines， and proteins related to the mesenchymal stem cells， osteoblasts， and osteoclasts， thereby weakening the osteogenic differentiation of mesenchymal stem cells， inhibiting osteoblast mineralization， and promoting the activation， proliferation， and maturation of osteoclasts. As a result， the dynamic imbalance between bone resorption and bone formation occurs， influencing bone remodeling and promoting the progression of OP. At the moment， anti-bone resorption drugs， bone formation-promoting drugs， and hormones are mainly used in clinical settings in western medicine. However， due to the long treatment cycle and the occurrence of serious gastrointestinal reactions， hypocalcemia， osteonecrosis， and others， patients show poor compliance and thus the effect is not as expected. Traditional Chinese medicine （TCM） demonstrates remarkable effect on OP attributing to the multi-pathway and multi-target characteristics. With low price and few adverse reactions， TCM is widely applied in clinical practice in comparison with western medicine. TCM has unique advantages in the treatment of OP by regulating oxidative stress. It exerts the therapeutic effect on OP by modulating different signaling pathways， providing new mindset for the treatment of this disease. Therefore， through literature research， this study summarized the research on mechanism of oxidative stress in OP and the treatment by TCM， which is expected to lay a foundation for further research.

Objective:To investigate the predictive effects of triglyceride-glucose index(TyG) 0 h, TyG 1 h, and TyG 2 h on type 2 diabetes mellitus(T2DM) in elderly male participants without diabetes.Methods:A total of 862 subjects were selected and followed up for 20 years, retrospectively. At baseline, all subjects underwent 75 g oral glucose tolerance test(OGTT) and venous plasma glucose measurements were taken before OGTT(FPG), 1 h and 2 h after OGTT(1 h-PG and 2 h-PG, respectively). Fasting blood lipids and other important biochemical indicators were also detected. The index of fasting serum triglycerides(TG) and FPG, 1 h-PG, 2 h-PG were TyG 0 h, TyG 1 h, TyG 2 h, respectively. Cox proportional hazards regression model and receiver operating characteristic(ROC) curve were used to evaluate the predictive effect of TyG 0 h, TyG 1 h, and TyG 2 h on T2DM.Results:The results of Cox regression model indicated that TyG 0 h, TyG 1 h and TyG 2 h had predictive effects on T2DM at 10 and 20 years of follow-up [At 10 years of follow-up, TyG 0 h: HR=1.538(95% CI 1.267-1.868), P<0.001; TyG 1 h: HR=2.224(95% CI 1.852-2.672), P<0.001; TyG 2 h: HR=2.117(95% CI 1.777-2.522), P<0.001; and after follow-up for 20 years, TyG 0 h: HR=1.431(95% CI 1.204-1.700), P<0.001; TyG 1 h: HR=2.008(95% CI 1.705-2.364), P<0.001; TyG 2 h: HR=1.850(95% CI 1.582-2.163), P<0.001]. After 10 years of follow-up, the area under the curve(AUC) of TyG 0 h, TyG 1 h, and TyG 2 h for predicting T2DM was 0.699, 0.747, and 0.739, respectively. Comparison of AUC, TyG 1 h or TyG 2 h>TyG 0 h. After 20 years of follow-up, AUC of TyG 0 h, TyG 1 h, and TyG 2 h for predicting T2DM was 0.671, 0.723, and 0.705, respectively. Comparison of AUC, TyG 1 h>TyG 2 h>TyG 0 h. Conclusion:The predictive role of TyG 1 h and TyG 2 h in T2DM is superior to TyG 0 h, and TyG 1 h′s long-term predictive effect on T2DM is better than TyG 2 h, which can be used as a reference index to evaluate the risk of T2DM in clinical practice.
