Skip metastasis at the esophageal resection margin in radical gastrectomy: clinical characteristics of 30 cases / 中华胃肠外科杂志

Objective: To summarize the clinical characteristics of patients with skip metastasis at esophageal resection margin during radical gastrectomy. Methods: This is a descriptive study of case series. Relevant data from 2006 to 2022 were collected from two major gastric cancer consultation and treatment centers: Nanjing Drum Tower Hospital and Jinling Hospital.Characteristics, surgical approach, number of dissected lymph nodes, immunohistochemical staining, and pathological staging were summarized and analyzed. The distribution of residual tumor cells at the esophageal margins was further analyzed at the cellular and tissue levels. Skip metastasis at the esophageal resection margin was defined as a negative esophageal margin with a positive margin in the cephalad donut. Results: Thirty (0.33%, 30/8972) eligible patients, 24 (80.0%) of whom were male, were identified in the two centers. The mean age was 63.9±11.0 years. Seventeen (56.7%) of these patients had papillary or tubular adenocarcinomas, including 13 (43.3%) poorly- and four (13.3%) moderately-differentiated tumors; four (13.3%) had signet-ring cell carcinomas; four (13.3%) mucinous adenocarcinomas; three (10.0%) mixed adenocarcinomas, including two with poorly-differentiated tubular adenocarcinomas mixed with signet-ring cell carcinoma and mucinous adenocarcinoma; and one had a poorly differentiated tubular adenocarcinoma mixed with signet-ring cell carcinoma. Two patients (6.7%) had other types of cancer, namely adenosquamous carcinoma in one patient and undifferentiated carcinoma in the other one. The predominant tumor sites were the lesser curvature (n=26, 86.7%) and the cardia (n=24, 80.0%). The mean tumor diameter was 6.6 cm, mean distance between tumor and esophageal resection margin was 1.5 cm, and proportions of tumor invasion into the dentate line, nerves, and vessels were 80.0% (24/30), 86.7%(26/30), and 93.3% (28/30), respectively. The mean number of lymph nodes resected was 20.4±8.9. The pathological stage was mainly T4 (n=18, 60.0%) and N3 (n=21, 70.0%), the median Ki67 was 52.7%, and the rates of positivity for HER2, EGFR, VEGFR, E-cadherin and PD-L1 were 40.0% (12/30), 46.7% (14/30), 80.0% (24/30), 86.7% (26/30) and 16.7% (5/30), respectively. At the cellular level, cancer cells were mainly distributed in small focal areas, as cell masses, or as tumor thrombi; large numbers of widely distributed atypic cells were seldom observed. At the tissue level, cancer cells were located in the mucosal layer in seven patients (23.3%), in the submucosal layer in 18 (60.0%), and in the muscular layer in five (16.7%); no cancer cells were identified in the outer membrane. Five of the seven tumors were located in the lamina propria, two in the muscularis mucosae, and none in the mucosal epithelium. Conclusion: Patients with skip metastasis at the esophageal resection margin at radical gastrectomy have unfavorable tumor biology and a high proliferation index, are at a late pathological stage, and the residual cancer is mostly located in the submucosa.

Mechanism of Acupuncture and Moxibustion on Promoting Mucosal Healing in Ulcerative Colitis / 中国结合医学杂志

The latest guideline about ulcerative colitis (UC) clinical practice stresses that mucosal healing, rather than anti-inflammation, is the main target in UC clinical management. Current mucosal dysfunction mainly closely relates to the endoscopic intestinal wall (mechanical barrier) injury with the imbalance between intestinal epithelial cells (IECs) regeneration and death, as well as tight junction (TJ) dysfunction. It is suggested that biological barrier (gut microbiota), chemical barrier (mucus protein layer, MUC) and immune barrier (immune cells) all take part in the imbalance, leading to mechanical barrier injury. Lots of experimental studies reported that acupuncture and moxibustion on UC recovery by adjusting the gut microbiota, MUC and immune cells on multiple targets and pathways, which contributes to the balance of IEC regeneration and death, as well as TJ structure recovery in animals. Moreover, the validity and superiority of acupuncture and moxibustion were also demonstrated in clinic. This study aims to review the achievements of acupuncture and moxibustion on mucosal healing and analyse the underlying mechanisms.

Common diseases and drug use of Pseudostellaria heterophylla / 中国中药杂志

Pseudostellaria heterophylla in large-scale cultivation needs to apply pesticides to control diseases, and non-standard use of pesticide may cause excessive pesticide residues in medicinal materials, increasing the risk of clinical medication. To accurately monitor the residual pesticides, this paper investigated the drug use during the process of P. heterophylla disease prevention in 25 P. he-terophylla planting enterprises or individual households in Guizhou province. It was found that there were 8 common diseases in P. he-terophylla planting, including leaf spot, downy mildew, virus disease, root rot, dropping disease, purple feather disease, white silk disease, and damping-off disease. Twenty-three kinds of pesticides were used in disease control, mainly chemical synthetic pesticides, accounting for 78.3%, followed by biological pesticides and mineral pesticides, accounting for 13.0% and 8.7%, respectively. The disease prevention and control drugs were all low-toxic pesticides, and there were no varieties banned in the Chinese Pharmacopoeia(2020 edition). However, the pesticides used have not been registered on P. heterophylla, and the excessive use of drugs was serious. The present monitoring of pesticide residues in P. heterophylla is mainly based on traditional pesticides such as organochlorine, organophosphorus, and carbamate, which does not effectively cover the production of drugs and had certain safety risks. It is suggested to speed up the research and registration of drug use in the production of P. heterophylla, increase the use of biological pesticides, and further improve the monitoring indicators of pesticide residues in combination with the actual production of drugs, so as to promote the high-quality development of P. heterophylla industry.

Research advance on structure and function of amides in Zanthoxylum plants / 中国中药杂志

Zanthoxylum belongs to the Rutaceae family, and there are 81 Zanthoxylum species and 36 varieties in China. Most of the Zanthoxylum plants are used as culinary spice. In recent years, scholars in China and abroad have carried out in-depth research on Zanthoxylum plants, and found that the peculiar numbing sensation of Zanthoxylum plants originates from amides. It is also determined that amides are an important material basis for exerting pharmacological effects, especially in anti-inflammatory analgesia, anesthesia and other aspects. In this paper, 123 amides in 26 Zanthoxylum plants and their pharmacological activity that have been reported were summarized, which provided scientific reference for the clinical application of Zanthoxylum plants and the research and development of new drugs, and also facilitated the sustainable development and utilization of Zanthoxylum plant resources.

Scientific basis of acupuncture on mesenchymal stem cells for treating ischemic stroke / 中国针灸

The scientific basis of acupuncture on mesenchymal stem cells (MSCs) for treating ischemic stroke (IS) is discussed. MSCs transplantation has great potential for the treatment of tissue damage caused by early stage inflammatory cascade reactions of IS, but its actual transformation is limited by various factors. How to improve the homing efficiency of MSCs is the primary issue to enhance its efficacy. As such, the possible mechanisms of acupuncture and MSCs transplantation in inhibiting inflammatory cascade reactions induced by IS are explored by reviewing literature, and a hypothesis that acupuncture could promote the secretion of stromal cell-derived factor-1α (SDF-1α) from ischemic foci to regulate SDF-1α/CXC chemokine receptor 4 (CXCR4) axis, thereby improving the homing efficiency of MSCs transplantation, exerting its neuroprotective function, and improving the bed transformation ability, is proposed.

Comparative and phylogeny analysis of Asarum caudigerum and A. cardiophyllum complete chloroplast genomes / 药学学报

The complete chloroplast genome of medicinal plant Asarum caudigerum Hance and its close relative A. cardiophyllum Franchet were sequenced using Illumina Hiseq technology, and assembled, annotated, and characterized by bioinformatic methods in this study. Then phylogenetic analysis of the complete chloroplast genomes of A. caudigerum, A. cardiophyllum, and twelve published species was conducted. The results indicated that the chloroplast genomes ranged from 186 215-186 985 bp in length, with a large single copy (LSC, 89 445-90 169 bp) and two inverted repeats (IRa/IRb, 48 387-48 408 bp). The overall GC content was 37.4%-37.5%. A total of 144 chloroplast genes were annotated, including 98 protein coding genes, 38 tRNA genes and 8 rRNA genes. In addition, complex genomic rearrangements were detected in the chloroplast genome of Asarum. Meanwhile, visual evaluation of the discrete type of the sequence indicated that the variation level of non-coding region was higher than that of coding region. Phylogenetic analyses suggested that A. caudigerum and A. cardiophyllum were clustered into a single clade and A. cardiophyllum, A. sieboldii var. seoulense, A. misandrum and A. maculatum were clustered into another single branch. These two clade were sister species. This study provides a scientific basis for the identification, phylogenetic relationship, molecular breeding of Asarum species.

Progress on the relationship between high-sugar diet and myopia development / 国际眼科杂志(Guoji Yanke Zazhi)

Myopia has become a major public health problem affecting the eye health of our nationals, especially adolescents, and is listed as one of the three major diseases in the world. The etiology of myopia is complex and it is currently considered to be mainly related to environmental factors and genetic factors. Dietary factors are less concerned, but it has been reported that there is a correlation between high-sugar diet and the occurrence and development of myopia. Studies have found that high-sugar diet can cause hyperinsulinemia, which mediates the increase of retinal insulin-like growth factor(IGF-1, IGF-2)expression level, and the decrease of insulin-like growth factor binding protein-3(IGFBP-3)expression level in scleral fibroblasts, thereby activating signal transduction and transcriptional activator protein 3(STAT3)signaling pathway, and then acting on scleral matrix metalloproteinases(MMP)/transforming growth factor-β(TGF-β)and other factors, resulting in a decrease in scleral extracellular matrix(ECM), eventually leading to scleral remodeling, eye axis growth and myopia. This article explores the relationship between high-sugar diet and the occurrence and development of myopia from the aspects of epidemiology and biological mechanisms by consulting relevant literature, and provides research directions for the prevention and control of myopia.

AIM:To explore the influence factors of the treatment zone diameter(TZD)and its correlation with axial length growth(ALG)after Paragon CRT orthokeratology.METHODS: Retrospective clinical study. The data of 226 myopic patients(226 eyes)wearing Paragon CRT orthokeratology from April 2020 to September 2022 were collect. The correlated factors of TZD after wearing lens for 1mo, and the relationship between the overlapping treatment zone/ pupil area ratio and the ALG after wearing lens for 1a were analyzed.RESULTS: After wearing lens for 1mo, the TZD was negatively correlated with central corneal thickness(CCT)and positively correlated with the flat corneal eccentricity. After wearing lens for 1a, the ALG of the small TZD group(0.25±0.18mm)was significantly smaller than that of the large TZD group(0.34±0.24mm, P=0.002), and the ALG of the small area ratio group(0.24±0.19mm)was significantly smaller than that of the large area ratio group(0.35±0.23mm,P&#x003C;0.001). Age and overlapping treatment zone area/pupil area ratio were significantly associated with the ALG in multivariate linear regression(all P&#x003C;0.05).CONCLUSION: The wearers with thicker CCT and smaller flat corneal eccentricity usually had smaller TZD, and both the TZD and the overlapping treatment zone area/pupil area ratio were correlated with the ALG.

Serum lipoprotein-associated phospholipase A2 level is positively correlated with the recurrence risk of acute ischemic cerebral infarction in hypertensive patients / 南方医科大学学报

OBJECTIVE@#To explore the relationship between serum lipoprotein-associated phospholipase A2 (Lp-PLA2) level and the risk of acute ischemic stroke (AIS) recurrence in hypertensive patients.@*METHODS@#This retrospective case-control study was conducted among 211 hypertensive patients with AIS treated in Foshan First People's Hospital, including 35 patients with recurrence of AIS during the 1-year follow-up as confirmed by head CT/MR. In the overall patients, 60 had grade 1 hypertension (including 5 recurrent cases), 76 had grade 2 hypertension (with 11 recurrent cases), and 75 had grade 3 hypertension (with 19 recurrent cases). Univariate analysis, multivariate logistic regression analysis, trend analysis, and smooth curve fitting analysis were performed to explore the correlation between serum Lp-PLA2 level within 24 h after admission and the risk of AIS recurrence. The predictive efficacy of serum Lp-PLA2 level for AIS recurrence in different hypertension grades was evaluated using ROC curve analysis.@*RESULTS@#Serum Lp-PLA2 level, age, NIHSS score at admission, mRS scores at 7 days, homocysteine level and smoking status differed significantly between patients with and without AIS recurrence (P < 0.05). After adjustment for confounding factors, multivariate regression analysis showed that the highest tertile of Lp-PLA2 level was associated with a 4.13-fold increase of AIS recurrence risk compared with the lowest tertile (OR=5.13, 95% CI: 1.35-19.40), and each 1 ng/mL increase of Lp-PLA2 level was associated with a 1% increase of AIS recurrence risk (OR= 1.01, 95% CI: 1.01-1.02). Serum Lp-PLA2 level was shown to positively correlate with AIS recurrence risk, and in patients with grade 3 hypertension, its areas under the ROC curve for predicting AIS recurrence was 0.869 with a specificity of 0.893 and a sensitivity of 0.737.@*CONCLUSION@#Serum Lp-PLA2 concentration is an independent risk factor and potentially an effective predictor for AIS recurrence in patients with grade 3 hypertension.

It is of great significance to establish animal models of CHF according to different etiologies to explore the pathogenesis of CHF and develop drugs to prevent and treat CHF induced by different diseases. Therefore, based on the classification of the etiology of CHF, this paper summarizes the animal models of CHF widely used in recent 10 years, and the application of these animal models in traditional Chinese medicine(TCM) research, in order to provide ideas and strategies for studying the pathogenesis and treatment of CHF, and provide ideas for TCM modernization research.

Regulation of ischemic stroke by circadian rhythm and intervention by traditional Chinese medicine / 中国中药杂志

Circadian rhythm is an internal regulatory mechanism formed in organisms in response to the circadian periodicity in the environment, which modulates the pathophysiological events, occurrence and development of diseases, and the response to treatment in mammals. It significantly influences the susceptibility, injury, and recovery of ischemic stroke, and the response to therapy. Accumulating evidence indicates that circadian rhythms not only regulate the important physiological factors of ischemic stroke events, such as blood pressure and coagulation-fibrinolysis system, but also participate in the immuno-inflammatory reaction mediated by glial cells and peripheral immune cells after ischemic injury and the regulation of neurovascular unit(NVU). This article aims to link molecular, cellular, and physiological pathways in circadian biology to the clinical consequences of ischemic stroke and to illustrate the impact of circadian rhythms on ischemic stroke pathogenesis, the regulation of NVU, and the immuno-inflammatory responses. The regulation of circadian rhythm by traditional Chinese medicine is reviewed, and the research progress of traditional Chinese medicine intervention in circadian rhythm is summarized to provide a reasonable and valuable reference for the follow-up traditional Chinese medicine research and molecular mechanism research of circadian rhythm.
