Colorectal cancer is a common and malignant tumor in the digestive tract. Invasion and metastasis of cancer cells are key factors leading to the high mortality rate and postoperative recurrence of colorectal cancer. Chemotherapy is the main treatment method for preventing recurrence of this disease. However, there are many toxic side effects in clinical application, which seriously hinder the treatment process. Therefore, it is imperative to search for efficient and low-toxicity drugs. Traditional Chinese medicine (TCM) has a long history of treating colorectal cancer and offers advantages such as safety, effectiveness, multiple targets, multiple pathways and minimal toxic side effects, which have made it increasingly popular worldwide. According to TCM, the pathogenesis of colorectal cancer is rooted in both deficiency and excess. TCM formulas mainly focus on tonifying the body to address the invasion and metastasis of colorectal cancer, such as Jianpi compound, Jianpi Xiaoai decoction, and Bushen Jiedu Sanjie decoction. TCM monomers, such as emodin, berberine, and tanshinone, mainly focus on clearing heat and removing toxin, circulating blood and transforming stasis, and resolving swelling and dispersing nodules. Signaling pathways play a crucial role for analyzing invasion and metastasis, and research has shown that pathways such as Wnt/β-catenin, phosphatidylinositol-3 kinase/protein kinase (PI3K/Akt), Janus kinase 2/signal transduction and transcription activating factor 3 (JAK2/STAT3), nuclear factors-κB (NF-κB), vascular endothelial growth factor (VEGF) play important roles in the invasion and metastasis of colorectal cancer. The invasion and metastasis of colorectal cancer can be inhibited via regulating the key proteins and related factors in these pathways. In this review, we searched various literature databases, such as PubMed, China National Knowledge Infrastructure (CNKI), and VIP, using keywords such as "colorectal cancer", "signaling pathway", "invasion and metastasis", and "traditional Chinese medicine", to summarize and analyze the relevant pathways of TCM compounds and monomers against invasion and metastasis of colorectal cancer published in the past five years. The review aims to provide new insights and references for in-depth research on the therapy for invasion and metastasis of colorectal cancer and new drug development.

Objective:To analyze the expression of topoisomerase Ⅱα(Topo Ⅱα) and cyclin G1 in gastric adenocarcinoma and their relationship with clinicopathological characteristics and Helicobacter pylori (Hp) infection.Methods:From May 2018 to May 2022, 217 gastric adenocarcinoma tissues and adjacent normal tissue samples were collected in Lu′an Hospital of Traditional Chinese Medicine. The streptavidin-peroxidase method (S-P) was used to detect the expression of Topo Ⅱα and cyclin G1. The expression of Topo Ⅱα and cyclin G1 in gastric adenocarcinoma tissues and adjacent normal tissues were compared. The relationship between Topo Ⅱα and cyclin G1 expression in gastric adenocarcinoma tissues and clinicopathological features were analyzed by univariate and multivariate Logistic regression. In addition, the Hp infection of gastric adenocarcinoma patients with different expressions of Topo Ⅱα and cyclin G1 was compared. Kendall tau-b correlation coefficient was used to analyze the correlation between Topo Ⅱα expression, cyclin G1 expression and Hp infection.Results:The positive rates of Topo Ⅱα and cyclin G1 in gastric adenocarcinoma were higher than those in adjacent tissues: 60.83%(132/217) vs. 29.95%(65/217), 62.67%(136/217) vs. 0, there were statistical differences ( χ2 = 41.73, 198.07, P<0.01). There were significant differences in the positive expression rates of Topo Ⅱα and cyclin G1 in gastric adenocarcinoma patients with different histological differentiation degrees, T stage, N stage and TNM stage ( P<0.05). The positive expression rate of Topo Ⅱα in gastric adenocarcinoma tissues with distant metastasis was significantly higher than that in gastric adenocarcinoma tissues without distant metastasis ( P<0.05). Multivariate Logistic regression analysis showed that histological differentiation degree, T stage, histological differentiation degree and N stage were the influencing factors of Topo Ⅱα expression ( P<0.05); histological differentiation degree, T stage, N stage, TNM stage were the influencing factor of cyclin G1 expression ( P<0.05). The positive rate of Hp in 217 patients with gastric adenocarcinoma was 81.57% (177/217). The positive rates of Hp in gastric adenocarcinoma patients with positive Topo Ⅱα and positive cyclin G1 were significantly higher than those with negative Topo Ⅱα and cyclin negative G1 expression: 87.12%(115/132) vs. 72.94%(62/85), 87.50% (119/136) vs. 71.60%(58/81), there were statistical differences ( χ2 = 6.92, 8.53, P<0.05). Kendall tau-b correlation coefficient analysis showed that the expression of Topo Ⅱα and cyclin G1 were positively correlated with Hp infection ( r = 0.179, 0.198, P<0.05). Conclusions:The positive rate of Topo Ⅱα and cyclin G1 in gastric adenocarcinoma is high, and it is correlated with histological differentiation, T stage, N stage and Hp infection.

OBJECTIVE To analyze the characteristics of levofloxacin-induced hypersensitivity reaction. METHODS Clinical pharmacists participated in the treatment for a case of levofloxacin-induced hypersensitivity reaction, and adjudged the relationship of levofloxacin with hypersensitivity reaction according to relative standards. Retrieved from CNKI, VIP, Wanfang database, PubMed and Embase, relevant literature about levofloxacin-induced hypersensitivity reaction was collected and analyzed. RESULTS Clinical pharmacists suggested checking the patient’s previous medication and allergy history based on symptoms such as fever and systemic rash, and determined that the drug hypersensitivity was “likely” or “highly likely” to be associated with levofloxacin. Clinicians provided symptomatic treatment to the patient based on the judgment of clinical pharmacists, and the patient improved after treatment. Results of the literature analysis showed that among 31 involved patients, there were 23 males and 8 females; 18 patients aged 50 and above; the incubation period of 24 patients was within 4 days after medication. The main adverse drug reactions were drug hypersensitivity syndrome, fixed drug eruption, erythema multiforme, etc. Most patients were improved after withdrawal and symptomatic treatment. CONCLUSIONS Hypersensitivity reaction is the rare adverse drug reaction of levofloxacin, mostly occurring within 2.5 h to 4 days after administration, and it is more likely to occur in middle-aged and elderly patients. Before clinical use, patients should be asked about their drug allergy history in detail; when patients experience fever or rash without obvious causes, medication should be stopped promptly and symptomatic treatment should be taken to ensure the safety and effectiveness of the patients’ medication.

Cardiopulmonary exercise test(CPET) is the most commonly used non-invasive tool in the world to objectively evaluate cardiopulmonary reserve function and exercise tolerance. CPET play an important role in diagnosis, risk stratification, prognosis evaluation and therapeutic planning in heart failure(HF) patients. In recent years, due to the increasing number of advanced HF patients and the paucity of heart donors, left ventricular assist device(LVAD) has represented a valid alternative to heart transplantation(HT) from bridge to transplantation indication to destination therapy. This article summarizes several topical issues regarding the current use of CPET in assessing the prognosis of HF patients, implantation and withdrawal of LVAD, postoperative right ventricular failure, and the effects of exercise rehabilitation in LVAD patients.

Drastic surges in intracellular reactive oxygen species (ROS) induce cell apoptosis, while most chemotherapy drugs lead to the accumulation of ROS. Here, we constructed an organic compound, arsenical N-(4-(1,3,2-dithiarsinan-2-yl)phenyl)acrylamide (AAZ2), which could prompt the ROS to trigger mitochondrial-dependent apoptosis in gastric cancer (GC). Mechanistically, by targeting pyruvate dehydrogenase kinase 1 (PDK1), AAZ2 caused metabolism alteration and the imbalance of redox homeostasis, followed by the inhibition of phosphoinositide-3-kinase (PI3K)/protein kinase B (AKT)/mammalian target of rapamycin (mTOR) pathway and leading to the activation of B-cell lymphoma 2 (Bcl2)/Bcl2-associated X (Bax)/caspase-9 (Cas9)/Cas3 cascades. Importantly, our in vivo data demonstrated that AAZ2 could inhibit the growth of GC xenograft. Overall, our data suggested that AAZ2 could contribute to metabolic abnormalities, leading to mitochondrial-dependent apoptosis by targeting PDK1 in GC.

ObjectiveTo identify the chemical constituents of Alismatis Rhizoma before and after processing with salt-water by ultra-high performance liquid chromatography-quadrupole-time-of-flight mass spectrometry (UPLC-Q-TOF-MS), and to investigate the changes of terpenoids in Alismatis Rhizoma before and after processing with salt-water. MethodUPLC-Q-TOF-MS was used to detect with 0.1% formic acid aqueous solution (A)-acetonitrile (B)as mobile phase for gradient elution (0-0.01 min, 20%B; 0.01-5 min, 20%-40%B; 5-40 min, 40%-95%B; 40-42 min, 95%B; 42-42.1 min, 95%-20%B; 42.1-45 min, 20%B), electrospray ionization (ESI) was selected for collection and detection in positive ion mode with the scanning range of m/z 100-1 250 and ion source temperature at 500 ℃. The data were analyzed by PeakView 1.2.0.3, the components were identified according to the primary and secondary MS data, and combined with the reference substance and literature. After normalized treatment by MarkerView 1.2.1, the MS data were analyzed by principal component analysis (PCA) and orthogonal partial least squares-discriminant analysis (OPLS-DA), and then the differential components before and after processing were screened. The content changes of differential components were analyzed according to the relative peak area. ResultA total of 30 components were identified under positive ion mode, including 28 prototerpene triterpenes and 2 sesquiterpenes. The results of PCA and OPLS-DA showed that there were significant differences in components from Alismatis Rhizoma before and after processing with salt-water, and 10 differential components (alisol B 23-acetate, alisol I, alismol, 11-deoxy-alisol B 23-acetate, alisol B, alisol C, 11-deoxy-alisol B, alisol G, 11-deoxy-alisol C and alisol A) were screened, and the contents of alisol G and alisol A decreased significantly after processing. ConclusionUPLC-Q-TOF-MS can comprehensively and accurately identify the chemical constituents in raw and salt-processed products of Alismatis Rhizoma. It takes a great difference in the contents of chemical constituents before and after processing, and the difference of substituents is the main reason for this differences, which can provide reference for determining the material basis of efficacy changes of Alismatis Rhizoma before and after processing with salt-water.

ObjectiveBy comparing the composition and content changes of the volatile components in Atractylodis Rhizoma before and after processing with rice-washed water, the effect of rice-washed water processing on volatile components in Atractylodis Rhizoma was investigated. MethodHeadspace-gas chromatography-mass spectrometry (HS-GC-MS) was used to detect the volatile components in rhizomes of Atractylodes chinensis and A. lancea, and their processed products of rice-washed water. Chromatographic conditions were programmed temperature (starting temperature of 50 ℃ for 2 min, rising to 120 ℃ with the speed of 10 ℃·min-1, then rising to 170 ℃ at 2.5 ℃·min-1, and rising to 240 ℃ at 10 ℃·min-1 for 3 min), the inlet temperature was 280 ℃, the split ratio was 10∶1, and the solvent delay time was 3 min. The conditions of mass spectrometry were electron bombardment ionization (EI) with ionization temperature at 230 ℃ and detection range of m/z 20-650. Then the relative content of each component was determined by the peak area normalization method. SIMCA 14.1 software was used to perform unsupervised principal component analysis (PCA) and supervised orthogonal partial least squares-discriminant analysis (OPLS-DA) on each sample data, the differential components of Atractylodis Rhizoma and its processed products were screened by the principle of variable importance in the projection (VIP) value>1. ResultA total of 60 components were identified, among which 40 were rhizomes of A. chinensis and 38 were its processed products, 46 were rhizomes of A. lancea and 47 were its processed products. PCA and OPLS-DA showed that the 4 kinds of Atractylodis Rhizoma samples were clustered into one category respectively, indicating that the volatile components of the two kinds of Atractylodis Rhizoma were significantly changed after processing with rice-washed water, and there were also significant differences in the volatile components of rhizomes of A. lancea and A. chinensis. The compound composition of Atractylodis Rhizoma and its processed products was basically the same, but the content of the compounds was significantly different. The differential components were mainly concentrated in monoterpenoids and sesquiterpenoids, and the content of monoterpenoids mostly showed a decreasing trend. ConclusionAfter processing with rice-washed water, the contents of volatile components in rhizomes of A. lancea and A. chinensis are significantly changed, and pinene, 3-carene, p-cymene, ocimene, terpinolene, atractylon, acetic acid and furfural can be used as difference markers before and after processing.
