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.

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.

OBJECTIVE:
To explore clinical rules based on the big data of the emergency department of the Second Affiliated Hospital of Guangzhou Medical University, and to establish an integrated platform for clinical research in emergency, which was finally applied to clinical practice.
METHODS:
Based on the hospital information system (HIS), laboratory information system (LIS), emergency specialty system, picture archiving and communication systems (PACS) and electronic medical record system of the Second Affiliated Hospital of Guangzhou Medical University, the structural and unstructured information of patients in the emergency department from March 2019 to April 2022 was extracted. By means of extraction and fusion, normalization and desensitization quality control, the database was established. In addition, data were extracted from the database for adult patients with pre screening triage level III and below who underwent emergency visits from March 2019 to April 2022, such as demographic characteristics, vital signs during pre screening triage, diagnosis and treatment characteristics, diagnosis and grading, time indicators, and outcome indicators, independent risk factors for poor prognosis in patients were analyzed.
RESULTS:
(1) The data of 338 681 patients in the emergency department of the Second Affiliated Hospital of Guangzhou Medical University from March 2019 to April 2022 were extracted, including 15 modules, such as demographic information, triage information, visit information, green pass and rescue information, diagnosis information, medical record information, laboratory examination overview, laboratory information, examination information, microbiological information, medication information, treatment information, hospitalization information, chest pain management and stroke management. The database ensured data visualization and operability. (2) Total 140 868 patients with pre-examination and triage level III and below were recruited from the emergency department database. The gender, age, type of admission to the hospital, pulse, blood pressure, Glasgow coma scale (GCS) and other indicators of the patients were included. Taking emergency admission to operating room, emergency admission to intervention room, emergency admission to intensive care unit (ICU) or emergency death as poor prognosis, the poor prognosis prediction model for patients with pre-examination and triage level III and below was constructed. The receiver operator characteristic curve and forest map results showed that the model had good predictive efficiency and could be used in clinical practice to reduce the risk of insufficient emergency pre-examination and triage.
CONCLUSIONS
The establishment of high-quality clinical database based on big data in emergency department is conducive to mining the clinical value of big data, assisting clinical decision-making, and improving the quality of clinical diagnosis and treatment.

Mulberry (Morus alba L.) leaf is a well-established traditional Chinese botanical and culinary resource. It has found widespread application in the management of diabetes. The bioactive constituents of mulberry leaf, specifically mulberry leaf flavonoids (MLFs), exhibit pronounced potential in the amelioration of type 2 diabetes (T2D). This potential is attributed to their ability to safeguard pancreatic β cells, enhance insulin resistance, and inhibit α-glucosidase activity. Our antecedent research findings underscore the substantial therapeutic efficacy of MLFs in treating T2D. However, the precise mechanistic underpinnings of MLF's anti-T2D effects remain the subject of inquiry. Activation of brown/beige adipocytes is a novel and promising strategy for T2D treatment. In the present study, our primary objective was to elucidate the impact of MLFs on adipose tissue browning in db/db mice and 3T3-L1 cells and elucidate its underlying mechanism. The results manifested that MLFs reduced body weight and food intake, alleviated hepatic steatosis, improved insulin sensitivity, and increased lipolysis and thermogenesis in db/db mice. Moreover, MLFs activated brown adipose tissue (BAT) and induced the browning of inguinal white adipose tissue (IWAT) and 3T3-L1 adipocytes by increasing the expressions of brown adipocyte marker genes and proteins such as uncoupling protein 1 (UCP1) and beige adipocyte marker genes such as transmembrane protein 26 (Tmem26), thereby promoting mitochondrial biogenesis. Mechanistically, MLFs facilitated the activation of BAT and the induction of WAT browning to ameliorate T2D primarily through the activation of AMP-activated protein kinase (AMPK)/sirtuin 1 (SIRT1)/peroxisome proliferator-activated receptor-gamma coactivator 1α (PGC-1α) signaling pathway. These findings highlight the unique capacity of MLF to counteract T2D by enhancing BAT activation and inducing browning of IWAT, thereby ameliorating glucose and lipid metabolism disorders. As such, MLFs emerge as a prospective and innovative browning agent for the treatment of T2D.

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.

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.

For the occupation of pre-hospital emergency resources, 43.24% (912/2 109) of acute alcoholism called 120 through 110 with empty vehicles of 36.79% (776/2 109), which were significantly higher than the acute cerebrovascular disease [3.83% (362/9 461), 5.80% (549/9 461), both P < 0.01], acute trauma [24.29% (1 708/7 033), 7.96% (560/7 033), both P < 0.01], acute circulation system disease [2.44% (90/3 694), 2.87% (106/3 694), both P < 0.01], and acute respiratory system disease [0.86% (31/3 606), 1.58% (57/3 606), both P < 0.01]. Furthermore, empty vehicles were more likely to happen through 110 with empty vehicles rate of 51.75% (472/912), which was significantly higher than that through the witness [40.82% (60/147), P < 0.01] and relatives and friends [23.24% (244/1 050), P < 0.01]. The driving time and on-site time of acute alcoholism were significantly shorter than those of acute cerebrovascular disease, acute circulation system disease, and acute respiratory system disease [driving time (minutes): 26 (20, 34) vs. 34 (26, 45), 38 (29, 49), 38 (29, 50); on-site time (minutes): 6 (4, 10) vs. 10 (7, 14), 10 (7, 15), 10 (8, 15), all P < 0.01], but there was no statistical difference as compared with acute trauma [driving time (minutes): 26 (20, 34) vs. 29 (20, 42), on-site time (minutes): 6 (4, 10) vs. 7 (4, 11), both P > 0.05]. The regularity of variation in number of critically acute alcoholism patients was distinctive, which peaked in the period of 21:00-00:00 and bottomed out in the period of 09:00-13:00, which overlapped with the peak flow in the hospital emergency department (17:00-22:00).
CONCLUSIONS
Acute alcoholism patients occupy excessive pre-hospital emergency resources, and overlap with the hospital emergency treatment peak. It is necessary to strengthen the public propaganda and education on the rational usage of 120 emergency resources and reduce waste.
