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.

Traditional medications used for treating autoimmune diseases often come with a wide range of adverse effects. Current treatments focus mainly on symptom management, resulting in significant health issues and financial burdens for patients. Recently, clinical research has demonstrated the potential of helminths and their derivatives as effective therapies for autoimmune disorders. Helminths, being a near-natural immunomodulator, exhibit milder effects than broad-spectrum immunosuppressants and corticosteroids, thereby presenting a promising alternative for the treatment of autoimmune diseases. However, different helminths' therapeutic efficacy and mechanisms and their derivatives in treating autoimmune diseases may vary. Therefore, we aim to review recent clinical advancements in the use of helminths and their derivatives for treating inflammatory bowel disease, multiple sclerosis, and autism spectrum disorder, with a view to offering novel clinical treatment approaches.

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.

BACKGROUND: In light of the significant clinical benefits of antibody-drug conjugates in clinical trials, the human epidermal growth factor receptor 2 (HER2)-low category in breast cancers has gained increasing attention. Therefore, we studied the clinicopathological characteristics of Chinese patients with hormone receptor (HR)-positive/HER2-low early-stage breast cancer and developed a recurrence risk prediction model. METHODS: Female patients with HR-positive/HER2-low early-stage breast cancer treated in 29 hospitals of the Chinese Society of Breast Surgery (CSBrS) from Jan 2015 to Dec 2016 were enrolled. Their clinicopathological data and prognostic information were collected, and machine learning methods were used to analyze the prognostic factors. RESULTS: In total, 25,096 patients were diagnosed with breast cancer in 29 hospitals of CSBrS from Jan 2015 to Dec 2016, and clinicopathological data for 6486 patients with HER2-low early-stage breast cancer were collected. Among them, 5629 patients (86.79%) were HR-positive. The median follow-up time was 57 months (4, 76 months); the 5-year disease-free survival (DFS) rate was 92.7%, and the 5-year overall survival (OS) rate was 97.7%. In total, 412 cases (7.31%) of metastasis were observed, and 124 (2.20%) patients died. Multivariate Cox regression analysis revealed that T stage, N stage, lymphovascular thrombosis, Ki-67 index, and prognostic stage were associated with recurrence and metastasis ( P <0.05). A recurrence risk prediction model was established using the random forest method and exhibited a sensitivity of 81.1%, specificity of 71.7%, positive predictive value of 74.1%, and negative predictive value of 79.2%. CONCLUSION: Most of patients with HER2-low early-stage breast cancer were HR-positive, and patients had favorable outcome; tumor N stage, lymphovascular thrombosis, Ki-67 index, and tumor prognostic stage were prognostic factors. The HR-positive/HER2-low early-stage breast cancer recurrence prediction model established based on the random forest method has a good reference value for predicting 5-year recurrence events.

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.

BACKGROUND: : Breast cancer with low-positive human epidermal growth factor receptor 2 (HER2) expression has triggered further refinement of evaluation criteria for HER2 expression. We studied the clinicopathological features of early-stage breast cancer with low-positive HER2 expression in China and analyzed prognostic factors. METHODS: : Clinical and pathological data and prognostic information of patients with early-stage breast cancer with low-positive HER2 expression treated by the member units of the Chinese Society of Breast Surgery and Chinese Society of Surgery of Chinese Medical Association, from January 2015 to December 2016 were collected. The prognostic factors of these patients were analyzed. RESULTS: : Twenty-nine hospitals provided valid cases. From 2015 to 2016, a total of 25,096 cases of early-stage breast cancer were treated, 7642 (30.5%) of which had low-positive HER2 expression and were included in the study. After ineligible cases were excluded, 6486 patients were included in the study. The median follow-up time was 57 months (4-76 months). The disease-free survival rate was 92.1% at 5 years, and the overall survival rate was 97.4% at 5 years. At the follow-up, 506 (7.8%) cases of metastasis and 167 (2.6%) deaths were noted. Multivariate Cox regression analysis showed that tumor stage, lymphvascular invasion, and the Ki67 index were related to recurrence and metastasis (P < 0.05). The recurrence risk prediction model was established using a machine learning model and showed that the area under the receiving operator characteristic curve was 0.815 (95% confidence interval: 0.750-0.880). CONCLUSIONS: : Early-stage breast cancer patients with low-positive HER2 expression account for 30.5% of all patients. Tumor stage, lymphvascular invasion, and the Ki67 index are factors affecting prognosis. The recurrence prediction model for breast cancer with low-positive HER2 expression based on a machine learning model had a good clinical reference value for predicting the recurrence risk at 5 years.

BACKGROUND: Pertuzumab has been approved for application in China by the National Medical Products Administration, and both national and international guidelines make recommendations for the use of neoadjuvant treatment with trastuzumab or trastuzumab + pertuzumab plus chemotherapy regimens for patients with indications. The goal of this study was to investigate the short-term clinical efficacy of the neoadjuvant therapies trastuzumab and trastuzumab+pertuzumab for patients with early human epidermal growth factor receptor 2 (HER2)-positive breast cancer in China. METHODS: A real-world study was conducted using the clinicopathological data of patients with early HER2-positive breast cancer who were admitted to the member hospitals of the Chinese Society of Breast Surgery, Chinese Surgical Society of Chinese Medical Association between March 2019 and December 2020. This study analyzed the efficacy and tolerance of trastuzumab+chemotherapy and trastuzumab+pertuzumab+chemotherapy in patients with early HER2-positive breast cancer. The Response Evaluation Criteria in Solid Tumors 1.1 was adopted to evaluate clinical efficacy. The pathological efficacy was evaluated using the MillerPayne grade. The Common Terminology Criteria for Adverse Events (version 5.0) was adopted to evaluate adverse events (AEs). The propensity scores were subjected to propensity score matching using the R language (1:1 matching with a maximum allowable difference of 0.05 between the two groups). Efficacy was compared using the chi-square test, and correlation analysis was performed using linear regression. RESULTS: A total of 1032 patients with early HER2-positive breast cancer met the enrollment criteria and were included in this study. Among these patients, 472 received neoadjuvant trastuzumab+chemotherapy (the trastuzumab group), and 560 received neoadjuvant trastuzumab+pertuzumab+chemotherapy (the trastuzumab+pertuzumab group). The overall pathologic complete response (pCR) rate was 47.2% (487/1032), while the pCR rates of the trastuzumab and trastuzumab+pertuzumab groups were 34.5% (163/472) and 57.9% (324/560), respectively, and the difference was significant (P < 0.001). The incidence of grade 4 AEs was 24/321 (7.5%) in the trastuzumab+pertuzumab group, and there were no cases in which the left ventricular ejection fraction decreased by more than 10%. CONCLUSIONS Patients in the trastuzumab+pertuzumab group had a higher pCR rate than those in the trastuzumab group, and the toxic side effects were tolerable.
