Traditional Chinese medicines (TCMs) possess a rich historical background, unique theoretical framework, remarkable therapeutic efficacy, and abundant resources. However, the modernization and internationalization of TCMs have faced significant obstacles due to their diverse ingredients and unknown mechanisms. To gain deeper insights into the phytochemicals and ensure the quality control of TCMs, there is an urgent need to enhance analytical techniques. Currently, two-dimensional (2D) chromatography, which incorporates two independent separation mechanisms, demonstrates superior separation capabilities compared to the traditional one-dimensional (1D) separation system when analyzing TCMs samples. Over the past decade, new techniques have been continuously developed to gain actionable insights from complex samples. This review presents the recent advancements in the application of multidimensional chromatography for the quality evaluation of TCMs, encompassing 2D-gas chromatography (GC), 2D-liquid chromatography (LC), as well as emerging three-dimensional (3D)-GC, 3D-LC, and their associated data-processing approaches. These studies highlight the promising potential of multidimensional chromatographic separation for future phytochemical analysis. Nevertheless, the increased separation capability has resulted in higher-order data sets and greater demands for data-processing tools. Considering that multidimensional chromatography is still a relatively nascent research field, further hardware enhancements and the implementation of chemometric methods are necessary to foster its robust development.

Objective To investigate the role and mechanism of circular RNA(circRNA)has_circ_0003304(circAZIN1)in regulating chondrocyte degeneration in osteoarthritis(OA).Methods Gene chip was used to detect the expression level of circRNA during the chondrogenic differentiation of human adipose-de-rived stem cells(hADSC).The circAZIN1 was further screened through the chondrocyte inflammation model constructed with interleukin-β(IL-β)and tumor necrosis factor-α(TNF-α)from the top 10 circRNAs with the most differentiated expression detected by gene chip.Real-time fluorescence quantitative polymerase chain re-action PCR(qPCR)was used to detect the effect of circAZIN1 overexpression(transfected with pcDNA3.1-circAZIN1-EF1-ZsGreen plasmid)on the metabolism of chondrocyte extracellular matrix(ECM).RNA-Pull down test was conducted to detect the protein bound by circAZIN1,miRNA-circRNA Interactions predicted the microRNAs(miRNAs)and their sites that circAZIN1 may be sponge-adsorbed,further TargetMiner,miRDB and TargetScan databases were applied to predict miRNAs which circAZIN1 may sponge-adsorbed.circAZIN1,miRNA and downstream mRNA were detected to find whether there was mirror regulation phe-nomenon after overexpression of miRNA.Results CircAZIN1 had the most significant differential expression during the chondrogenic differentiation of hADSC(day 3 and day 21)and in the chondrocyty inflammation model constructed by IL-β,TNF-α(day 3 group vs.day 21 group,the conttrol group vs.the IL-β group,the control group vs.the TNF-α group).Overexpression of circAZIN1 could promote the ECM synthesis in chon-drocytes and inhibit its decomposition.RNA-Pull down test result showed that circAZIN1 obviously bound AGO2 protein,suggesting that circAZIN1 had a high possibility of sponge adsorbing miRNAs.Further data-base predicted that its downstream was hsa-miR-654-3p,and the downstream mRNA of hsa-miR-654-3p was CACNA1I.After the overexpression of hsa-miR-654-3p,qPCR test found that circAZIN1,hsa-miR-654-3p and CACNA1I had a mirror image regulation phenomenon.Conclusion circAZIN1 inhibits the silencing effect of CACNA1I through sponge adsorption of hsa-miR-654-3p and thus plays a role in inhibiting chondrocyte de-generation,which provides a reference for the study of the regulatory mechanism of circRNA in the develop-ment of OA.

Liver failure is a serious clinical syndrome of liver disease with critical condition and high mortality, and besides liver transplantation, there is still a lack of satisfactory radical treatment methods. The pathogenesis of liver failure is complex and remains unclear, involving a variety of factors that affect the balance of hepatocyte necrosis and regeneration. This article summarizes autophagy as the key pathway for maintaining cell homeostasis and points out that autophagy plays an important protective role in the pathogenesis of liver failure by regulating NLRP3 inflammasome activation, reducing oxidative stress, and inhibiting cell apoptosis. Meanwhile, it is believed that the molecular signaling pathways targeting autophagy, such as exosomes and peroxisome proliferator-activated receptor α, participate in antagonizing the development and progression of liver failure and will become important ideas and directions for molecular targeted therapies for liver failure.

Objective:To analyze the clinical efficacy and safety of endoluminal treatment of complex renal artery aneurysm (RAA).Methods:The clinical data and follow-up results of 19 patients with complex RAA admitted to Renji Hospital, Shanghai Jiaotong University School of Medicine from November 2014 to September 2021 were retrospectively analyzed. Two patients were treated with simple spring coil embolization into the aneurysmal artery, 14 patients were treated with simple spring coil embolization of the aneurysmal cavity, and 3 patients were treated with stent-assisted + spring coil embolization technique. Based on the location of the aneurysm, RAA were classified into type Ⅰ, Ⅱ, and Ⅲ. 7 patients with type Ⅰ, 10 patients with type Ⅱ, and 2 patients with type Ⅲ were studied. Variance analysis was used to compare the differences in glomerular filtration rate(GFR) of the affected side when the tumor was located at different locations, and Pearson was used to analyze the correlation between the number of coils implanted and the size of the tumor and GFR.Results:Ten of the 19 patients who were underwent successful endoluminal intervention. The average size of the patients′ aneurysms was (20.89±6.65) mm, and the average number of spring coils implanted was 8.22±3.08. The preoperative and postoperative serum creatinine were in the normal range, and no RAA tumor enlargement or recurrence was found during the follow-up period. The postoperative GFR was abnormal in patients with type Ⅰ, type Ⅱ, and type Ⅲ renal aneurysms, and the mean GFR value differed among the three types of patients( P=0.003). There was a negative correlation between the postoperative GFR values of the affected kidney and the number of spring coils implanted ( P=0.047), and no significant relationship between GFR and aneurysm size. Conclusion:The endovascular technique is an effective and safe means of treating complex RAA.

Objective To investigate the characteristics of mental rotation in stroke patients and the relationship between mental rotation and visual-spatial cognitive function. Methods From March, 2012 to October, 2013, 30 stroke patients were selected as experimental group and 30 healthy subjects as control group. They were tested with hand mental rotation task, and assessed with visuospatial abilities from Mon-treal Cognitive Assessment (MoCA). Results The reaction time of hand mental rotation task was significantly longer in the experimental group than in the control group (F=95.6, P<0.001). The reaction time was longer with the increase of rotation angle in both groups, and was the longest as 180° of rotation (F=345.672, P<0.001). The response accuracy rate of hand mental rotation task was significantly lower in the experimental group than in the control group (F=6.444, P<0.05). The response accuracy rate was lower with the increase of rotation angle in both groups, and was the least as 180° of rotation (F=102.911, P<0.001). The reaction time negatively correlated with the score of visuospa-tial abilities, while the response accuracy rate positively correlated with it in the stroke patients (P<0.05). Conclusion The mental rotation ability is impaired in stroke patients, however, the respondent pattern is similar to healthy people. The mental rotation ability is correlated with visual-spatial cognitive functions in stroke patients.
