Monotropein is a compound classified into iridoid which is found in herbaceous plants Morindae officinalis. It possesses anti-inflammatory, antioxidant, and anti-osteoarthritic activities. Previous study indicates that monotropein may have the potential to combat cardiovascular disease, although the related mechanism remains unclear. In this study, we constructed the model of atherosclerosis by oxidized low density lipoprotein-induced vascular smooth muscle cells and LDLR –/–mice given high-fat diet to investigate the effects of monotropein on atherosclerosis.Our results showed that monotropein treatment significantly reduced the area of atherosclerotic plaques and necrotic cores in mice, inhibited the proliferation and migration of vascular smooth muscle cells, and reduced inflammatory responses and oxidative stress, which in turn alleviated atherosclerosis. In addition, we found that monotropein reduced the expression levels of P-NF-κB and P-AP-1. In conclusion, our data suggest that monotropein inhibited the proliferation and migration of vascular smooth muscle cells by mediating the activity of NF-κB, AP-1, reducing the level of inflammation and oxidative stress, and thus resisting the development of atherosclerosis. These findings demonstrate the efficacious therapeutic impact of monotropein on atherosclerosis and elucidate its specific target.

OBJECTIVE To enrich the polymethoxyflavonoid-rich fraction from Citri Reticulatae Pericarpium using D101 macro-porous resin,and further to analyse the chemical constituents using High-Performance Liquid Chromatography Quadrupole-Time-of-Flight Mass Spectrometry(HPLC-Q-TOF-MS).METHODS Citri Reticulatae Pericarpium extract was adsorbed on D101 macro-porous resin and then eluted with different concentrations of ethanol to enrich the polymethoxyflavonoid-rich fraction;the content of the major flavonoid components was determined by high-performance liquid chromatography(HPLC);and the components were further an-alysed by HPLC-Q-TOF-MS.RESULTS The established HPLC method for the simultaneous determination of seven flavonoids in Citri Reticulatae Pericarpium extract was accurate and reliable.The contents of compounds such as nobiletin and tangeritin were signifi-cantly increased in the polymethoxyflavonoid-rich fraction.Using high resolution mass spectrometry(HRMS),70 and 60 compounds were identified from the Citri Reticulatae Pericarpium extract and the polymethoxyflavonoid-rich fraction,respectively,with 53 polyme-thoxyflavonoids being detected in these two extracts.CONCLUSION The results of this study provide an experimental basis for fur-ther identification of the pharmacological substance basis of the polymethoxyflavonoids in Citri Reticulatae Pericarpium and the estab-lishment of quality control methods.

Social anxiety disorder has a significant negative impact on individuals'social interaction and normal life,and childhood trauma plays an important role in the occurrence and development of SAD.Childhood trauma affects the development of self-awareness,impairs the ability of information processing,hinders the normal development of prefrontal cortex-limbic system loop and default mode network,and causes abnormal secretion of glucocorticoid and oxytocin,which leads to individuals'inability to correctly understand social clues and reasonably regulate emotions,and thus unable to produce adaptive emotional and behavioral responses in social situations,which may lead to SAD.In conclusion,childhood trauma has a lasting adverse effect on social function from both psychological and physiological aspects.

Hyperuricemic nephropathy （HN）， a secondary renal damage common in clinical practice， is characterized by early concealing and continuous progression. The understanding of HN in traditional Chinese medicine （TCM） is from a macroscopic perspective. According to the TCM theory， HN is caused by the combination of external pathogens and internal injuries， with the main pathogenesis being root deficiency combined with superficial excess and deficiency-excess in complexity. In western medicine， the understanding of HN is from the microscopic perspective， which holds that the occurrence of HN is the result of inflammation， oxidative stress， renin-angiotensin-aldosterone system （RAAS） activation， and metabolic abnormalities. The TCM syndromes of HN include internal dampness and heat， obstruction in dampness and turbidity， deficiency of spleen and kidney， and deficiency of kidney yin. Accordingly， the prescriptions should clear heat and dampness， remove dampness and turbidity， tonify spleen and kidney， and nourish kidney yin， respectively. In addition to TCM prescriptions， single herbal medicines and their extracts， Chinese patent medicines， and external applications of Chinese medicines have played a significant role in the treatment of HN， promoting the application of TCM in the treatment of HN. Moreover， the integrated traditional Chinese and western medicine has also played a role in the treatment of HN， enriching the treatment schemes of HN. Different from common kidney diseases such as acute and chronic glomerulonephritis and nephrotic syndrome， HN with particularity should be carefully differentiated in clinical practice. This article systematically summarizes the research progress in the treatment of traditional Chinese medicine and integrated traditional Chinese and western medicine on hyperuricemic nephropathy with TCM and integrated traditional Chinese and western medicine， aiming to enrich the system and theory of HN treatment and further guide the clinical practice.

Objective:To investigate the symptom clusters and influencing factors among breast cancer patients receiving aromatase inhibitor treatment and to provide a theoretical basis for the symptom clusters management.Methods:From April 2020 to January 2021, 253 breast cancer patients were recruited in Peking University Cancer Hospital by convenient sampling method. All the patients were cross-sectional investigated by the demographic and clinical characteristics questionnaire, the M.D. Anderson Symptom Inventory, the Hospital Anxiety and Depression Scale. The principal component analysis was used to extract the symptom clusters and the multiple linear regression was used to analyze the risk factors.Results:During the period of breast cancer patients receiving aromatase inhibitor treatment, three symptom clusters were identified: sick symptom cluster, treatment related-psychological symptom cluster, digestive symptoms cluster. The prevalence of the three symptom clusters was 49.4%(125/253), 45.1%(114/253), 22.5%(57/253), respectively. The median severity of the three symptom clusters was 2.80, 2.00, 0.67, respectively. Multiple linear regression analysis showed that anxiety and education level were the influencing factors of sick symptom cluster ( β=0.25, -0.25, all P<0.05), anxiety, depression and educational level were the influencing factors of treatment related-psychological symptom cluster ( β = 0.34, 0.20, -0.16, all P<0.05), anxiety, depression and chemotherapy history were the influencing factors of digestive symptom cluster ( β= 0.17, 0.18, -0.13, all P<0.05). Conclusions:Breast cancer patients with aromatase inhibitor treatment are affected by symptom clusters. In order to relieve the symptom clusters, we need pay attention to the mentation, the education level and prerious treatment of the patients.

Diabetic kidney diseases （DKD） is one of the main microvascular complications of diabetes. According to the available studies， the initial factor of DKD is glomerular injury. However， in recent years， more and more studies have confirmed that renal tubular injury plays a key role in the development of DKD. Taking renal tubules and their interstitium as therapeutic targets has become a new idea for the treatment of DKD. Traditional Chinese medicine （TCM） can treat renal tubular injury in DKD via multiple pathways， targets， and links， demonstrating significant therapeutic effect and slight side effects. According to the etiology and pathogenesis of DKD， doctors differentiate different syndromes such as deficiency of both Qi and Yin， deficiency of spleen and kidney Yang， and Qi deficiency and blood stasis and then adopt the therapies of nourishing kidney and strengthening essence， clearing heat and eliminating dampness， tonifying Qi and nourishing yin and so on， which have shown significant effect in the treatment of renal tubular injury in DKD. This paper summarizes the experimental studies about the treatment of renal tubular injury in DKD by TCM compound prescriptions， as well as the effective parts， extracts， and active ingredient of Chinese herbal medicines. Chinese herbal medicines and their derivates can regulate Toll-like receptor 4 （TLR4）/nuclear factor-κB （NF-κB）， nuclear factor erythroid 2-related factor 2 （Nrf2）/antioxidant response element （ARE）， transforming growth factor-β₁ （TGF-β₁）/Smads and other signaling pathways to treat renal tubular injury from resisting oxidative stress， inhibiting apoptosis of renal tubular epithelial cells， and blocking renal tubular epithelial-mesenchymal transformation. With this review， we hope to provide a theoretical basis for the development and clinical application of new drugs for renal tubular injury in DKD.
