Pathological Mechanism of Diabetes Based on NF-κB Signaling Pathway and Traditional Chinese Medicine Intervention： A Review / 中国实验方剂学杂志

As people's living standards improve， the development trend of diabetes has gradually become severe. Diabetes is a chronic inflammatory disease associated with abnormal expression of nuclear factor-kappa B （NF-κB） in patients. NF-κB exists in various tissue cells and participates in the regulation of a variety of genes related to immune function and inflammation. Varieties of factors can activate NF-κB when the body is stimulated by external factors， so as to produce inflammation and other reactions. Previous studies on NF-κB mainly focus on cancer， and the pathological mechanism of the treatment of diabetes by related signaling pathways and the progress of traditional Chinese medicine （TCM） treatment have not been systematically elaborated on. By referring to the relevant literature in China and abroad， it was found that NF-κB is not isolated in the development and progression of diabetes but is associated with signal molecules related to inflammation， oxidative stress， and energy metabolism， and it is involved in mediating inflammation， pancreatic β cell apoptosis， insulin signal transduction， and other physiological functions. Therefore， blocking the transmission of NF-κB signaling pathway is beneficial to the treatment of diabetes. At present， Western medicine for the treatment of diabetes mainly includes oral hypoglycemic drugs and insulin injections， but the adverse reactions are obvious. TCM has been characterized by multi-target， extensive action， and excellent curative effects in the treatment of diabetes. TCM and its compounds with functions of tonifying Qi and promoting blood circulation， regulating qi and eliminating phlegm， clearing heat and detoxifying， and nourishing Yin and moistening dryness can effectively intervene in the abnormal expression of NF-κB signaling pathway in vivo through anti-inflammatory effects. In this paper， the association between NF-κB signaling pathway and diabetes was summarized， and the modern research progress of TCM intervention of NF-κB signaling pathway in the treatment of diabetes in the past five years was reviewed， so as to lay a laboratory foundation for the study of a new pathological mechanism of diabetes based on NF-κB signaling pathway and provide new targets and research direction for the prevention and treatment of diabetes and development of related TCM.

Rutin Promotes Browning of 3T3-L1 Preadipocytes and Its Mechanism / 中国实验方剂学杂志

ObjectiveTo investigate the effect of rutin on the browning of 3T3-L1 preadipocytes and the mechanism. MethodCell counting kit-8 （CCK-8） assay was used to detect the effect of different concentration of rutin （3.125， 6.25， 12.5， 25， 50， 100， 200 μmol·L-1） on 3T3-L1 cell activity， and Western blot to examine the effect of rutin （12.5， 25， 50 μmol·L-1） on the expression of thermogenesis-associated proteins uncoupling protein 1 （UCP1）， PR domain containing 16 （PRDM16） and peroxisome proliferator-activated receptor γ coactivator-1α （PGC-1α） in adipocytes. After the optimal concentration of rutin was determined， the effect of rutin on lipid droplet formation in adipocytes was observed based on oil red O staining， and the expression of nuclear respiratory factor 1 （NRF1）， nuclear respiratory factor 2 （NRF2） and mitochondrial transcription factor A （TFAM）， which were the landmark proteins of mitochondrial biosynthesis， was detected by Western blot. ResultCompared with the blank group， 200 μmol·L-1 rutin inhibited 3T3-L1 cell activity （P<0.01）. Compared with the blank group， at the concentration of 12.5， 25， 50 μmol·L-1 rutin significantly promoted the expression of thermogenesis-associated proteins （UCP1， PRDM16， and PGC-1α） （P<0.01）， which was determined as the optimal concentration. Compared with the blank group， 50 μmol·L-1 rutin significantly increased the immunofluorescence intensity of mitochondrial UCP1 protein in 3T3-L1 cells （P<0.01） and the expression of the markers of mitochondrial biosynthesis （NRF1， NRF2， and TFAM） （P<0.01）. In addition， 50 μmol·L-1 rutin significantly inhibited lipid droplet formation of 3T3-L1 adipocytes （P<0.01）. ConclusionRutin inhibited lipid droplet deposition in 3T3-L1 adipocytes and increased the expression of thermogenesis-related proteins （UCP1， PRDM16， and PGC-1α） and markers of mitochondrial biosynthesis （NRF1， NRF2， and TFAM）， thereby inducing the browning of 3T3-L1 adipocytes. This lays a basis for the development of drugs that safely regulate the browning of white cells.

TGF-β-related Signaling Pathways in Pathogenesis of Diabetes and Prospect of Chinese Medicine Intervention： A Review / 中国实验方剂学杂志

The incidence of diabetes has been on the rise as the result of lifestyle changes， especially the high-fat diet and reduced exercise. Thus， it has become a global public health problem and it is an urgent task to explore effective therapy. There has been an explosion of research on the relationship of transforming growth factor-β （TGF-β） signaling pathways with diabetes complications and tumors， but the role of the pathways in the occurrence and progression of diabetes remains unclear. TGF-β signaling pathways can be activated by many factors， directly or indirectly leading to the apoptosis of islet β cells and insulin resistance （IR）， and thus they are expected to become new targets for the treatment of diabetes. TGF-β-related signaling pathways involve AMP-activated proteinkinase （AMPK）， protooncogene （c-Myc）， Ski-relatednovel protein N （SnoN）， Smad ubiquitination regulatory factor 1 （Smurf1）， miR-335-5p， and other signaling molecules. They participate in the occurrence and development of IR， apoptosis of islet β cells， insulin secretion disorder， fibrosis of adipocytes， and metabolic disorder of adipocytes， and inhibit the browning of white adipose tissue， playing an important part in the pathological process of human diabetes. According to traditional Chinese medicine （TCM）， the pathogenesis of diabetes is the deficiency of Qi and Yin， and the late stage is characterized by the syndrome of Qi deficiency， and Yang deficiency and blood stasis， which should be treated according to the principle of replenishing Qi and nourishing Yin， warming Yang and activating blood. It has been found that the efficacy of some Chinese medicinals and compound prescriptions on diabetes is closely related to the TGF-β signaling pathways. This paper reviews TGF-β-associated signaling pathways， elucidating the roles of them in pathogenesis of diabetes， and analyzes the relationship of TGF-β-associated signaling pathways with the effect of compound Chinese medicine prescriptions against diabetes. This study is expected to lay a theoretical basis for the research on the treatment diabetes.

Total Flavonoids of Mulberry Leaves Improves Liver Lipid Metabolism in Type 2 Diabetic Rats by Regulating PPAR-α/CPT-1 Pathway / 中国实验方剂学杂志

ObjectiveTo investigate the medicinal effect of total flavonoids of mulberry leaves on regulating liver lipid metabolism disorder in diabetes mellitus type 2 （T2DM） rats， and the mechanism based on liver peroxidase proliferators activate receptors-α （PPAR-α） and carnitine palmityl transferase-1 （CPT-1） proteins. MethodTotal flavonoids of mulberry leaves were extracted and purified by ethanol extraction + macroporous resin purification and then identified. T2DM rat model was induced by high fat diet （HFD） + streptozocin（STZ）method. Rats with blood glucose ≥ 11.1 mmol·L-1 were divided into three administration groups with the high dose （300 mg·kg-1）， medium dose （150 mg·kg-1）， and low dose （75 mg·kg-1） of total flavonoids of mulberry leaves for 8 weeks， respectively， to observe the weight and blood glucose of the rats. The pathological changes of rat livers were observed by hematoxylin-eosin （HE） staining. Biochemical method was used to detect the levels of total cholesterol （TC）， triglyceride （TG）， low density lipoprotein-cholesterol （LDL-C）， and high density lipoprotein-cholesterol （HDL-C） of blood lipid metabolism in rats. The messenger ribonucleic acid （mRNA） and protein expressions of PPAR-α and CPT-1 were determined by real-time quantitative polymerase chain reaction （Real-time PCR） and Western blot. ResultAfter 8 weeks of intervention of total flavonoids of mulberry leaves， compared with the control group， the food intake， liver index， and fasting blood glucose of rats in the model group increased significantly （P<0.01）. Compared with the model group， the food intake， fasting blood glucose， and liver index of rats in the administration groups decreased significantly （P<0.01）. The results of HE staining showed that the liver tissue structure of rats in the control group was complete and there was no obvious abnormality. The model group showed vacuolar degeneration and inflammatory infiltration of hepatocytes of rats. There was no obvious abnormality in the liver structure of rats in the administration groups. The results of blood lipid showed that compared with the control group， the levels of TC， TG， and LDL-C increased significantly （P<0.01）， but the level of HDL-C decreased significantly （P<0.01） in the model group. Compared with the model group， the levels of TC， TG， and LDL-C decreased significantly （P<0.05， P<0.01）， whereas the level of HDL-C increased significantly （P<0.01） in the administration groups. The results of Real-time PCR showed that compared with the control group， the mRNA expression of PPAR-α and CPT-1 of rats in the model group decreased significantly （P<0.01）. Compared with the model group， the mRNA expressions of PPAR-α and CPT-1 of rats in the high-dose group increased significantly （P<0.01）. The results of Western blot showed that compared with the control group， the protein expressions of PPAR-α and CPT-1 of rats in the model group decreased significantly （P<0.01）. Compared with the model group， the protein expressions of PPAR-α and CPT-1 of rats in the high-dose group increased significantly （P<0.05， P<0.01）. ConclusionTotal flavonoids of mulberry leaves can effectively reduce blood glucose and improve liver lipid metabolism disorder in T2DM rats. The total flavonoids of mulberry leaves could regulate lipid metabolism and play a hypoglycemic role by activating and regulating PPAR-α and CPT-1 proteins and promoting oxidative decomposition of fatty acids.

Comparison between discectomy combined with transpedicular dynamic stabilization and transforaminal lumbar interbody fusion in the treatment of single-level lumbar disc herniation / 中华骨科杂志

Objective:To compare the clinical effects of discectomy combined with transpedicular dynamic stabilization and transforaminal lumbar interbody fusion (TLIF) in treating single-level lumbar disc herniation.Methods:From November 2012 to November 2015, a total of 96 patients with single-level lumbar disc herniation (disc height decreased more than 1/3, the width of the basilar part of the herniated disc >6 mm, massive disc herniation or Modic type I endplate changes) treated by discectomy combined with Dynesys dynamic stabilization (Dynesys group, n=48) or TLIF (fusion group, n=48) were enrolled. Clinical assessments included operation duration, intraoperative blood loss, MacNab score, visual analogue scale (VAS), Oswestry disability index (ODI) and rate of complications. Radiographs were evaluated for lumbar mobility, intervertebral height, etc. Results:A total of 86 patients were included in the final analysis (44 in Dynesys group and 42 in fusion group) and were evaluated after 5 years follow-up. The operation duration of Dynesys group (159.61±37.29 min) was less than that of the fusion group (177.42±39.90 min) significantly ( t=2.140, P=0.035). Intraoperative blood loss in Dynesys group (151.78±50.88 ml) was less than that in fusion group (197.74±76.55 ml) with significant difference ( t=3.293, P=0.001). At 5 years follow-up, there were 2 cases with screw loosening and 5 cases with adjacent segmental degeneration in Dynesys group without symptom. In fusion group, there were 12 cases with adjacent segmental degeneration and two of them with symptom. There were significant differences in the incidence of adjacent segment degeneration between the two groups ( χ2=4.012, P=0.045). According to the MacNab criteria, excellent or good cases accounted for 95% in Dynesys group and 93% in fusion group without significant differences ( Z=0.425, P=0.671). VAS back, VAS leg and ODI scores were improved significantly in both groups after 2 years and 5 years ( P<0.05). However, there were no significant differences between the two groups ( P<0.05). The activity of the surgical segment was 4.59°±0.48° in Dynesys group and 1.00°±0.42° in fusion group at 5 years after surgery. The height of intervertebral space in Dynesys group decreased from 11.19±2.07 mm before surgery to 9.98±2.02 mm at 2 years after surgery and to 9.86±1.64 mm at 5 years after surgery ( F=6.462, P=0.002). However, there was no statistically significant difference between the 2 and 5 years follow-up ( q=0.415, P>0.05). At 5 years after surgery, the activity of the first proximal segment in the two groups was 9.74°±3.29° and 11.69°±3.89°, respectively ( t=2.514, P=0.014). Conclusion:Both discectomy combined with dynamic stabilization and TLIF can achieve satisfied clinical effects in treating single-level lumbar disc herniation. Dynamic stabilization preserves the intervertebral activity of surgical segments and results in a lower incidence of adjacent segment degeneration compared with that in fusion surgery. Furthermore, discectomy combined with dynamic stabilization is a less invasive intervention with shorter operation duration and less blood loss compared with TLIF.

Self-propelled nanomotor reconstructs tumor microenvironment through synergistic hypoxia alleviation and glycolysis inhibition for promoted anti-metastasis

Solid tumors always exhibit local hypoxia, resulting in the high metastasis and inertness to chemotherapy. Reconstruction of hypoxic tumor microenvironment (TME) is considered a potential therapy compared to directly killing tumor cells. However, the insufficient oxygen delivery to deep tumor and the confronting "Warburg effect" compromise the efficacy of hypoxia alleviation. Herein, we construct a cascade enzyme-powered nanomotor (NM-si), which can simultaneously provide sufficient oxygen in deep tumor and inhibit the aerobic glycolysis to potentiate anti-metastasis in chemotherapy. Catalase (Cat) and glucose oxidase (GOx) are co-adsorbed on our previously reported CAuNCs@HA to form self-propelled nanomotor (NM), with hexokinase-2 (HK-2) siRNA further condensed (NM-si). The persistent production of oxygen bubbles from the cascade enzymatic reaction propels NM-si to move forward autonomously and in a controllable direction along H

Advances in therapeutic targets-related study on systemic lupus erythematosus / 中南大学学报(医学版)

Systemic lupus erythematosus (SLE) is a chronic and autoimmunity-mediated diffuse connective tissue disease. The mainstay of treatments for SLE mainly relies on corticosteroids and immunosuppressants, which have a series of unavoidable side effects. Therefore, it is of fundamental importance to search novel therapeutic targets for better treatment with favorable efficacy and minor side effects. Recent studies shed light on potential therapeutic targets for SLE, mainly covering the followings: B-cell/plasmocyte-related targets [B cell activating factor (BAFF), a proliferation-inducing ligand (APRIL), CD20, CD22, CD19/FcγRIIb, Bruton tyrosine kinase (Btk), and proteasome], T cell-related targets [calcineurin, mammalian target of rapamycin (mTOR), regulatory factor X1 (RFX1), and Rho kinase], macrophage-related targets (macrophage migration inhibitory factor), intracellular signaling molecules, cytokines (cereblon, histone deacetylase 6, Janus activated kinase/signal transducer and activator of transcription), co-stimulating factors (CD28/B7, CD40/CD154), IgE autoantibody, and gut microbiome. Among them, belimumab (a humanized monoclonal antibody against B-lymphocyte stimulator) and telitacicept (a recombinant human B-lymphocyte stimulator receptor-antibody fusion protein) have been sequentially approved for the clinical treatment of SLE in China. A variety of new targeted-therapy drugs are in the Phase 2 or Phase 3 clinical trials,among which anifrolumab (a human monoclonal antibody against type I interferon receptor subunit 1) has completed a Phase 3 clinical trial with good responses achieved, although its incidence of herpes zoster is higher than that in the control group. The research progress in both molecular mechanisms and new drug development for different therapeutic targets have greatly promoted our better and in-depth understanding of the pathogenesis of SLE, and have also reflected the complexity and heterogeneity of the disease. Successful development and clinical application of more novel therapies would no doubt usher in a new era of individualized treatment for SLE in the future.

Status of social avoidance and distress in emerging adults with Type 1 diabetes mellitus and its association with self-management and glycemic control / 中南大学学报(医学版)

: Emerging adult patients with Type 1 diabetes mellitus (T1DM) appear to have a reduced opportunities on learning and exercise, a decreased skill in learning and work, a lower degree of social support due to fear and avoidance of social interaction. This study aimed to assess the level of social avoidance and distress in emerging adults with T1DM, and to explore the correlation between social avoidance and distress and self-management or glycemic control. : A total of 342 T1DM patients aged 18-30 years old were recruited from 8 tertiary hospitals in Hunan Province from September 2014 to February 2019. The questionnaire included general information questionnaire, the Social Avoidance and Distress Scale (SAD), and Self-management Scale of Type 1 Diabetes for Chinese Adults (SMOD-CA). The total scores of SAD in emerging adult patients with T1DM were compared with those of norm. Correlation between glycated hemoglobin (HbA1c) and social avoidance and distress of emerging adult patients with T1DM was analyzed. : The total score of SAD (11.13±6.18) in emerging adults with T1DM was significantly higher than that in healthy adults (=77.06, <0.01). Pearson correlation analysis showed that the scores of SAD, social avoidance subscale, and social distress subscale were negatively correlated with the scores of SMOD-CA (all <0.01), and they were positively correlated with HbA1c (all <0.01). Multivariate linear regression analysis showed that social avoidance and distress, self-management, gender, and educational level were independent influential factors for HbA1c in emerging adults with T1DM. : The degree of social avoidance and distress of emerging adult patients with T1DM is higher than that of healthy people. The higher the degree of social avoidance and distress, the lower the level of self-management and the worse the control of blood sugar. Attention should be paid to social avoidance and distress in emerging adults with T1DM, and targeted interventions should be formulated.

Structural equation model of the relationship between sense of coherence,social support and coping style of permanent colostomy / 中国实用护理杂志

Objective To explore the levels of sense of coherence,social support and coping style of permanent colostomy,and explicit the relationships among the three variables.the structural equation model(SEM) was used to investigate the relationship of the three variables in order to provide the theory basis for patients with permanent colostomy. Methods Self designed questionnaire,Sense of coherence scale, Medical Coping Modes Questionnaire and social support Scale were used to investigate 172 permanent colostomy patients from two grade 3 class A hospitals in Harbin. Results The total score of SOC in patients with permanent colostomy was (65.09 ± 11.71) points;The total score of social support in patients with permanent colostomy was (42.60 ± 7.26) points;the three subscales of medical coping modes questionnaire in descending sequence were avoidance, confrontation and acceptance-resignation with (18.53 ± 2.82), (17.37 ± 5.48), (9.49 ± 3.25) points. The abusive social support and coping style were significantly correlated to sense of coherence (P< 0.01 for both). Moreover, sense of coherence can be predicted directly by social support,and predicted indirectly via the mediating effect of coping style. Conclusion Effective measures should be taken to improve social support and via coping style to improve sense of coherence.
