Effect of different composite plates on the healing of femoral fractures.

In this paper, the effects of different composite plates on the healing of femoral fractures were studied by numerical simulation. The healing model of femoral fracture was established by ABAQUS display solver. Based on the fuzzy logic theory, the process of callus differentiation at femoral fracture was considered under the joint action of biological variables and mechanical stimulation, and the healing process of femur was simulated. Compare the stress on the screw, concentration of callus bone and cartilage, and callus healing performance of the carbon/epoxy composite (WSN3k) plate, glass/polypropylene composite (Twintex) plate, and stainless steel plate at various stages of bone healing, and investigate the impact of composite plates on the bone healing process. The results showed that the modulus of the plate had a notable impact on bone healing. Compared to stainless steel plate, the composite plate (due to its lower stiffness) exhibiting superior healing performance. Altering the sequence of composite laminates may modify the bone healing efficiency, and the wsn3k [0]18 composite plate exhibits superior healing performance.

Effect of Sarcopenia on 10-Year Risk of Atherosclerotic Cardiovascular Disease in Patients with Type 2 Diabetes Mellitus.

Objective: To investigate the impact of sarcopenia on the 10-year risk of atherosclerotic cardiovascular disease (ASCVD) among individuals with type 2 diabetes mellitus (T2DM). Methods: This study included the clinical, laboratory, and body composition data of 1491 patients with T2DM who were admitted to the Department of Endocrinology and Metabolism at Tianjin Union Medical Center from July 2018 to July 2023. The China-PAR model was utilized to evaluate cardiovascular disease risk. Associations between ASCVD risk and various clinical parameters were analyzed, and the relationship between body composition parameters and ASCVD risk was assessed using logistic regression. Results: The analysis revealed that T2DM patients with sarcopenia had a higher 10-year ASCVD risk compared to those without sarcopenia, with reduced muscle mass independently predicting an increased risk of cardiovascular disease. This association was significant among female T2DM patients, while male T2DM patients with sarcopenia showed a marginally higher median ASCVD risk compared to their non-sarcopenic counterparts. ASCVD risk inversely correlated with body muscle parameters and positively correlated with fat content parameters. Specifically, height- and weight-adjusted fat mass (FM, FM%, FMI) were identified as risk factors for ASCVD. Conversely, muscle parameters adjusted for weight and fat (ASM%, SMM%, FFM%, ASM/FM, SMM/FM, FMM/FM) were protective against ASCVD risk. These findings highlight the critical role of sarcopenia in influencing cardiovascular disease risk among Chinese patients with T2DM, as predicted by the China-PAR model. Conclusion: This study highlights the importance of sarcopenia in T2DM patients, not only as an indicator of ASCVD risk, but possibly as an independent risk factor in this demographics.

Cancer-associated fibroblasts promote enzalutamide resistance and PD-L1 expression in prostate cancer through CCL5-CCR5 paracrine axis.

Cancer-associated fibroblasts (CAFs) have been shown to play a key role in prostate cancer treatment resistance, but the role of CAFs in the initial course of enzalutamide therapy for prostate cancer remains unclear. Our research revealed that CAFs secrete CCL5, which promotes the upregulation of androgen receptor (AR) expression in prostate cancer cells, leading to resistance to enzalutamide therapy. Furthermore, CCL5 also enhances the expression of tumor programmed death-ligand 1 (PD-L1), resulting in immune escape. Mechanistically, CCL5 binds to the receptor CCR5 on prostate cancer cells and activates the AKT signaling pathway, leading to the upregulation of AR and PD-L1. The CCR5 antagonist maraviroc to inhibit the CAFs mediated CCL5 signaling pathway can effectively reduce the expression of AR and PD-L1, and improve the efficacy of enzalutamide. This study highlights a promising therapeutic approach targeting the CCL5-CCR5 signaling pathway to improve the effectiveness of enzalutamide.

Phage transcriptional regulator X (PtrX)-mediated augmentation of toxin production and virulence in Clostridioides difficile strain R20291.

Clostridioides difficile is a Gram-positive, anaerobic, and spore-forming bacterial member of the human gut microbiome. The primary virulence factors of C. difficile are toxin A and toxin B. These toxins damage the cell cytoskeleton and cause various diseases, from diarrhea to severe pseudomembranous colitis. Evidence suggests that bacteriophages can regulate the expression of the pathogenicity locus (PaLoc) genes of C. difficile. We previously demonstrated that the genome of the C. difficile RT027 strain NCKUH-21 contains a prophage-like DNA sequence, which was found to be markedly similar to that of the φCD38-2 phage. In the present study, we investigated the mechanisms underlying the φNCKUH-21-mediated regulation of the pathogenicity and the PaLoc genes expression in the lysogenized C. difficile strain R20291. The carriage of φNCKUH-21 in R20291 cells substantially enhanced toxin production, bacterial motility, biofilm formation, and spore germination in vitro. Subsequent mouse studies revealed that the lysogenized R20291 strain caused a more severe infection than the wild-type strain. We screened three φNCKUH-21 genes encoding DNA-binding proteins to check their effects on PaLoc genes expression. The overexpression of NCKUH-21_03890, annotated as a transcriptional regulator (phage transcriptional regulator X, PtrX), considerably enhanced toxin production, biofilm formation, and bacterial motility of R20291. Transcriptome analysis further confirmed that the overexpression of ptrX led to the upregulation of the expression of toxin genes, flagellar genes, and csrA. In the ptrX-overexpressing R20291 strain, PtrX influenced the expression of flagellar genes and the sigma factor gene sigD, possibly through an increased flagellar phase ON configuration ratio.

Risk factors for cognitive impairment in middle-aged type 2 diabetic patients: a cross-sectional study.

OBJECTIVE: The aim of this study was to investigate risk factors for cognitive impairment (CI) and explore the relationship between obesity and cognition in hospitalised middle-aged patients with type 2 diabetes (T2DM). METHODS: Subjects were divided into normal cognitive function (NCF) (n=320) and CI (n=204) groups based on the results of the Montreal Cognitive Assessment (MoCA) and Mini-Mental State Examination (MMSE). The risk factors for CI were determined by logistic regression analysis and generalised linear modelling. The associations between obesity parameters (body mass index (BMI) and waist circumference (WC)) and cognitive ability were studied with the use of linear regression analysis, piecewise regression modelling and interaction analysis. The receiver operating characteristic curve analysis was used to examine the diagnostic value of influencing factors for cc RESULTS: The prevalence of CI was 38.9% in hospitalised middle-aged T2DM patients (median age, 58 years). Age, WC, hypoglycaemic episode within past 3 months and cerebrovascular disease (CVD) were identified as independent risk factors for CI, while the independent protective factors were education, diabetic dietary pattern, overweight and obesity. BMI was a protective factor for the MoCA score within a certain range, whereas WC was a risk factor for the MMSE and MoCA scores. The area under the curve for the combination of BMI and WC was 0.754 (p<0.001). CONCLUSION: Age, education, diabetic dietary pattern, WC, overweight, obesity, hypoglycaemic episode in 3 months and CVD may be potential influencing factors for the occurrence of CI in hospitalised middle-aged population with T2DM. The combination of BMI and WC may represent a good predictor for early screening of CI in this population. Nevertheless, more relevant prospective studies are still needed.

Expression of SEC61G in Oral Squamous Cell Carcinoma and Its Prognostic Value / 肿瘤防治研究

Objective To analyze the expression of SEC61G in oral squamous cell carcinoma (OSCC) tissues and cell lines and determine its correlations with the clinicopathological features and prognosis of patients with OSCC. Methods The expression of SEC61G in OSCC tissues and its diagnostic and prognostic value were detected in the TCGA database. The expression levels of SEC61G in paraffin-embedded OSCC tissues and adjacent normal tissue specimens of 64 patients with OSCC were detected by immunohistochemistry. The correlation of SEC61G expression in OSCC tissues with the clinicopathological features was analyzed. Kaplan-Meier survival curve analysis showed that the expression of SEC61G correlated with the overall survival time of patients with OSCC. Cox regression analysis was used to analyze prognostic influence factors. Results The expression of SEC61G in OSCC tissues was significantly higher than that in para-carcinoma tissues (P < 0.05), consistent with the results of the TCGA database analysis, and its expression was closely related to N stage and clinical stage (P < 0.05). The overall survival of patients with OSCC in the group with low SEC61G expression was significantly higher than that in the high SEC61G expression group (P < 0.05). N stage and SEC61G expression were the prognostic influence factors for patients with OSCC (P < 0.05). SEC61G expression was an independent predictor of the prognosis of patients with OSCC (P < 0.05, AUC=0.923). Conclusion SEC61G is highly expressed in OSCC tissues and associated with N stage and clinical stage. Its high expression is associated with poor prognosis of patients. It may be a diagnostic biomarker for OSCC.

Different anchorages can affect the position of maxillary third molars in extraction treatment / 中国组织工程研究

BACKGROUND: In orthodontic treatment, different anchorage controls will make different effects on the maxillary third molar. Whether this can affect the normal eruption of maxillary third molar remains unclear. OBJECTIVE: To explore the effect of Physiologic Anchorage Spee-Wire System (PASS) treatment on impacted maxillary third molars, and to provide reference for clinical application. METHODS: Thirty patients with maxillary third molars were treated with PASS and 30 patients were treated with McLaughlin, Bennett, and Trevisi (MBT). All patients chose the plan of extracting four first premolars. The angles and distances were measured before and after treatment and statistical analysis was performed. The study was in accordance with the ethical requirements of the Fifth Affiliated Hospital of Xinjiang Medical University. All participants and their guardians signed the informed consents. RESULTS AND CONCLUSION: (1) In the PASS group, the ∠UM3-HP, ∠UM2-HP and U-ES were significantly increased (P=0.00), and the UM3-OP was significantly decreased (P=0.00), indicating that the maxillary second molar and third molar became more upright, and larger eruption space contributed to eruption. (2) Compared with the PASS group, the obliquity of the maxillary third molar in the MBT group showed significant change, while the vertical eruption rate in the PASS group was relatively larger. (3) These results imply that both PASS and MBT can improve the eruption angle and space of the third molar, and make it easier to erupt in orthodontic treatment of extraction of the first premolar.

Resistance training improves functional sympatholysis in persons with primary hypertension / 中华物理医学与康复杂志

Objective:To explore the effect of twelve weeks of resistance training on the functional sympatholysis of the skeletal muscles in persons with primary hypertension.Methods:Thirty untreated adult men with stage 1 essential hypertension (SBP/DBP: 140-159/90-99mmHg) formed a hypertension group, while thirty healthy counterparts (SBP/DBP: 90-120/60-80mmHg) served as a control group. Both groups underwent 12 weeks of progressive resistance training, 3 times a week. Before and after the intervention, any changes in forearm haemodynamics at rest were measured, along with handgrip after activation of the sympathetic nerve using a cold pressor test (CPT). The sympathetic vasoconstriction response was represented by the rate of change in brachial vascular conductance (%FVC) induced by the CPT, and the ability to suppress sympathetic vasoconstrictor responses using muscle contractions (functional sympatholysis) was quantified as the difference in sympathetic vasoconstrictor response between the handgrip test and at rest (△%FVC).Results:There were no significant differences between the two groups in their average △%FVCs before the intervention. After the intervention, significant increases were observed in both groups, but there was still no significant difference between the two groups′ average △%FVCs.Conclusion:Twelve weeks of resistance training can improve the functional sympatholysis of adult men with essential hypertension. Their elevated blood pressure does not impair functional sympatholysis.

Roles of miRNA and lncRNA in triple-negative breast cancer / 浙江大学学报（英文版）（B辑：生物医学和生物技术）

Triple-negative breast cancer (TNBC) is currently the most malignant subtype of breast cancer without effective targeted therapies, which makes its pathogenesis an important target for research. A growing number of studies have shown that non-coding RNA (ncRNA), including microRNA (miRNA) and long non-coding RNA (lncRNA), plays a significant role in tumorigenesis. This review summarizes the roles of miRNA and lncRNA in the progression, diagnosis, and neoadjuvant chemotherapy of TNBC. Aberrantly expressed miRNA and lncRNA are listed according to their roles. Further, it describes the multiple mechanisms that lncRNA shows for regulating gene expression in the nucleus and cytoplasm, and more importantly, describes lncRNA-regulated TNBC progression through complete combining with miRNA at the post-transcriptional level. Focusing on miRNA and lncRNA associated with TNBC can provide new insights for early diagnosis and treatment-they can be targeted in the future as a novel anticancer target of TNBC.

Effects of Electroacupuncture on Metabolic Changes in Motor Cortex and Striatum of 6-Hydroxydopamine-Induced Parkinsonian Rats / 中国结合医学杂志

OBJECTIVE@#To explore the possible underlying mechanism by investigating the effect of electroacupuncture (EA) treatment on the primary motor cortex and striatum in a unilateral 6-hydroxydopamine (6-OHDA) induced rat Parkinson's disease (PD) model.@*METHODS@#Male Sprague-Dawley rats were randomly divided into sham group (n=16), model group (n=14), and EA group (n=14). EA stimulation at Dazhui (GV 14) and Baihui (GV20) was applied to PD rats in the EA group for 4 weeks. Behavioral tests were conducted to evaluate the effectiveness of EA treatment. Metabolites were detected by 7.0 T proton nuclear magnetic resonance.@*RESULTS@#Following 4 weeks of EA treatment in PD model rats, the abnormal behavioral impairment induced by 6-OHDA was alleviated. In monitoring changes in metabolic activity, ratios of myoinositol/creatine (Cr) and N-acetyl aspartate (NAA)/Cr in the primary motor cortex were significantly lower at the injected side than the non-injected side in PD rats (P=0.024 and 0.020). The ratios of glutamate + glutamine (Glx)/Cr and NAA/Cr in the striatum were higher and lower, respectively, at the injected side than the non-injected side (P=0.046 and 0.008). EA treatment restored the balance of metabolic activity in the primary motor cortex and striatum. In addition, the taurine/Cr ratio and Glx/Cr ratio were elevated in the striatum of PD model rats compared to sham-lesioned rats (P=0.026 and 0.000). EA treatment alleviated the excessive glutamatergic transmission by down-regulating the striatal Glx/Cr ratio (P=0.001). The Glx/Cr ratio was negatively correlated with floor plane spontaneous locomotion in PD rats (P=0.027 and P=0.0007).@*CONCLUSIONS@#EA treatment is able to normalize the metabolic balance in the primary motor cortex and striatum of PD rats, which may contribute to its therapeutic effect on motor deficits. The striatal Glx/Cr ratio may serve as a potential indicator of PD and a therapeutic target of EA treatment.
