The liver, skeletal muscle, and adipose tissue are central energy-metabolizing organs and insulin-sensitive tissues, playing a crucial role in maintaining glucose homeostasis. As the powerhouse of the cell, mitochondria not only regulate insulin secretion but also oversee the oxidative phosphorylation and β-oxidation of fatty acids, processes vital for the metabolism of carbohydrates and fats, as well as the synthesis of ATP. The mitochondrial quality control system is of paramount importance for sustaining mitochondrial homeostasis, achieved through mechanisms such as protein homeostasis, mitochondrial dynamics, mitophagy, and biogenesis. Evidence suggests that dysfunctional mitochondria may significantly contribute to insulin resistance and ectopic fat storage in the liver, offering new insights into the strong correlation between mitochondrial dysfunction and the development of obesity, diabetes mellitus type 2 (T2DM), and non-alcoholic fatty liver disease (NAFLD). This manuscript aims to delve into the precise mechanisms by which imbalances in mitochondrial quality control lead to metabolic disorders in the liver, skeletal muscle, and adipose tissue, the 3 major insulin-sensitive organs. In the liver, mitochondrial dysfunction can lead to disturbances in glucose and lipid metabolism, resulting in insulin resistance and fat accumulation—a key factor in the development of NAFLD. In skeletal muscle, reduced mitochondrial function can decrease ATP production, weakening the muscle’s ability to uptake glucose, thereby exacerbating insulin resistance. In adipose tissue, mitochondrial dysfunction can impair adipocyte function, leading to lipotoxicity and inflammatory responses,which further contribute to insulin resistance and the onset of metabolic syndrome. Moreover, the interorgan crosstalk among these 3 tissues is essential for overall metabolic homeostasis. For instance, hepatic gluconeogenesis and glucose utilization in skeletal muscle are both influenced by the health status of their respective mitochondrial populations. The conversion between different types of adipose tissue and the ability to store lipids depend on normal mitochondrial function to avert ectopic fat accumulation in other organs. In summary, this manuscript emphasizes the critical role of mitochondrial quality control in maintaining the metabolic stability of the liver, skeletal muscle, and adipose tissue. It elucidates the specific mechanisms by which mitochondrial dysfunction in these organs contributes to the development of metabolic diseases, providing a foundation for future research and the development of therapeutic strategies targeting mitochondrial dysfunction.

Diabetic cardiomyopathy(DCM)is one of the complications of diabetes.The onset of DCM is hidden and easy to be ignored.Myocardial injury is serious in the later stage and the prognosis is poor.At present,symptomatic treatment is the main clinical treatment.Cuproptosis is a novel cell death mode caused by imbalanced copper ion concentration in the body,leading to mitochondrial metabolic abnormalities,which is one of the important mechanisms of DCM.Targeted cuproptosis pathway therapy for DCM is currently a focus and hotspot of research.The"Qi Luo Theory"is one of the disciplinary branches of the theory of collateral diseases,which mainly operates the meridian Qi system.The syndrome and treatment system of collateral diseases cardiovascular diseases have important guiding significance for the treatment of DCM.Traditional Chinese medicine believes that deficiency and stagnation of Qi that in the collaterals are the root causes of DCM,with stasis and toxin obstructing collaterals and damage to the heart collaterals being the core of the disease.The ultimate outcome is the deficiency and decline of Qi,Blood,Yin,and Yang in the heart.The"Qi Luo Theory"and cuproptosis have similarities in physiological functions and pathological processes,and cuproptosis can be said to be one of the microscopic manifestations of the"Qi Luo theory".Based on this,the staged treatment principle of tonifying deficiency and promoting stagnation as the norm,attacking and supplementing simultaneously as the principle,and strengthening the body and consolidating the core has been proposed,in order to provide theoretical reference for the clinical treatment of DCM.

Objective To investigate the regulatory effect of miR-132-3p on calmodulin-binding transcription activator 1(CAMTA1)and Schwann cell activity in rats with facial nerve injury(FNI)treated with I-125 seeds.Methods Rat Schwann cells were irradiated with I-125 seeds and transfected with miR-132-3p mimic,miR-132-3p inhibitor or sh-CAMTA1.The expressions of S100B and β-tubulin Ⅲ in the cells were detected with immunofluorescence assay,and the expressions of miR-132-3p and CAMTA1 protein were determined using RT-qPCR and Western blotting,respectively.EdU staining and Transwell assay were used to evaluate the changes in cell proliferation and migration ability.In a rat model of FNI,I-125 seeds were implanted into the facial tissues near the facial nerve 2 weeks before modeling,and miR-132-3p mimic was injected subcutaneously in the face after modeling.The pathologies of the facial nerve was assessed by HE,LFB and immunofluorescence staining.The targeting relationship between miR-132-3p and CAMTA1 was verified using StarBase v2.0 database and dual-luciferase reporter assay.Results Rat Schwann cells showed high expressions of S100B and β-tubulin Ⅲ.I-125 seeds radiation significantly decreased miR-132-3p expression and repressed proliferation and migration of the cells(P<0.001).Overexpression of miR-132-3p or CAMTA1 knockdown obviously enhanced proliferation and migration of the Schwann cells,while miR-132-3p knockdown produced the opposite effect.MiR-132-3p negatively regulated CAMTA1 expression.In the rat models of FNI,miR-132-3p injection significantly inhibited CAMTA1 expression and attenuated I-125 seeds-induced exacerbation of FNI.Conclusion Overexpression of miR-132-3p suppresses CAMTA1 expression and promotes Schwann cell proliferation and migration to alleviate I-125 seeds-induced exacerbation of FNI in rats.

BACKGROUND:The pedicle navigation template has many advantages,but there are still some problems.For example,poor soft tissue dissection leads to poor adhesion of the pedicle navigation template,resulting in screw path deviation;careful dissection of soft tissue to fit the pedicle navigation template leads to prolonged surgery time and increased bleeding;the design of the pedicle navigation template cannot predict the vertebral rotation and the impact of body position changes,resulting in the poor fitting. OBJECTIVE:To explore the utility of a new 5-point positioning point-contact pedicle navigation template in the case of scoliosis and complex pedicle. METHODS:A total of 20 patients with scoliosis and complicated pedicle admitted to the Department of Spinal Surgery,Guizhou Hospital,Beijing Jishuitan Hospital from February 2020 to February 2023 were selected for scoliosis orthopedics.During the operation,the 5-point positioning point-contact pedicle navigation template was used to guide the screws.According to the inclusion and exclusion criteria,34 cases were matched as the empirical nail placement group,and conventional barehanded nail placement was performed.The time of placement,the amount of bleeding,the number of fluoroscopies,the number of manual diversions,the level and accuracy of pedicle screws,the complications of placement,and the rate of correction of main curvature were compared between the two groups. RESULTS AND CONCLUSION:(1)There were no significant differences in sex,age,coronal Cobb's angle of the main curvature,bending Cobb's angle of the main curvature,pedicle variation,apex rotation,fusion segment,number of screws,level of screws,accuracy of screws,and rate of correction of main curvature between the navigation template group and the empirical nail placement group(P>0.05).(2)Compared with the empirical nail placement group,the navigation template group had more advantages in time of placement(P=0.034),amount of bleeding(P=0.036),number of fluoroscopies(P=0.000)and number of manual diversions(P=0.021).(3)There were 0 cases of screw-related complications in both groups.(4)In conclusion,the 5-point positioning point-contact 3D printing pedicle navigation template has a claw-like structure.It can firmly adapt to various deformities of the lamina articular process,avoid drift,and accurately place the screws.It has a point-like contact lamina structure to avoid extensive and complete dissection of the posterior structure,and reduce bleeding,operation time,and trauma.Pre-designed screw entry points and directions can reduce the number of fluoroscopy and operation time.Segmental design can avoid discomfort due to changes in anesthesia position.The operation is simple and the accuracy of screw placement is high.
