Objective: To investigate trends in incidence and mortality of colorectal cancer in Nantong City, Jiangsu Province from 2013 to 2022. Methods: Data on incidence and mortality of colorectal cancer from 2013 to 2022 in Nantong City were collected through the Nantong City cancer registry. The crude incidence, crude mortality, average age at onset, and average age at death of colorectal cancer were calculated. Chinese population-standardized incidence, Chinese population-standardized mortality, Chinese population-standardized average age at onset and Chinese population-standardized average age at death were calculated using the age structure of the standard population from the Fifth National Population Census in 2000. Trends in incidence and mortality of lung cancer from 2013 to 2022 were evaluated using average annual percent change (AAPC). Trends in the Chinese population-standardized average age at onset and Chinese population-standardized average age at death of lung cancer from 2013 to 2022 were evaluated using the linear regression model. Results: From 2013 to 2022, the crude incidence and Chinese population-standardized incidence of colorectal cancer in Nantong City increased from 33.63/105 and 16.05/105 to 53.82/105 and 19.62/105, respectively, showing upward trends (AAPC=5.665% and 2.467%, both P<0.05). The crude mortality increased from 15.99/105 in 2013 to 25.65/105 in 2022, also showing an upward trend (AAPC=5.514%, P<0.05), while no statistically significant trend was found in the Chinese population-standardized mortality (P>0.05). The Chinese population-standardized incidence of colorectal cancer showed upward trends in both males and females (AAPC=2.666% and 1.790%, both P<0.05). The Chinese population-standardized mortality showed an upward trend in males (AAPC=1.966%, P<0.05), but no statistically significant trend was found in females (P>0.05). The crude incidence of colorectal cancer in the groups aged 40-<50 years, 50-<60 years, 60-<70 years, 70-<80 years, and ≥80 years showed upward trends (AAPC=4.045%, 2.833%, 2.300%, 1.948%, and 1.775%, all P<0.05), and the crude mortality in the group aged ≥80 years showed an upward trend (AAPC=3.240%, P<0.05). The average age at onset of colorectal cancer increased at an annual average of 0.156 years (P<0.05), while the trend in the Chinese population-standardized average age at onset was not statistically significant (P>0.05). The average age at death and the Chinese population-standardized average age at death increased at an annual average of 0.325 and 0.153 years, respectively (both P<0.05). Conclusions From 2013 to 2022, both the crude incidence and mortality of colorectal cancer in Nantong City showed upward trends. Males and individuals aged ≥40 years faced a higher risk of both incidence and mortality. It is recommended to implement comprehensive prevention and control measures targeting these high-risk populations to reduce the burden of colorectal cancer.

Objective To investigate the effect of Jiawei Simiao powder on the Toll-like receptor 4(TLR4)/nuclear factor-κB(NF-κB)signaling pathway through miR-146a in monosodium urate(MSU)crystal-induced RAW264.7 macrophage inflammation models,and to explore its anti-inflammatory mechanism.Methods A cell model of gouty arthritis was established by inducing RAW264.7 cells with MSU crystals.Cells were divided into control,model,Jiawei Simiao powder,and colchicine groups and cell viability was assessed using the CCK-8 method.Levels of interleukin(IL)-1β,IL-6,and tumor necrosis factor(TNF)-α were measured by enzyme-linked immunosorbent assay.Expression levels of miR-146a miRNA and TLR4,myeloid differentiation factor 88(MyD88),TNF receptor-associated factor 6(TRAF6),and NF-κB p65 mRNA were detected by quantitative real-time polymerase chain reaction amplification technology,and protein expression levels of TLR4,MyD88,TRAF6,and phospho(p)-NF-κB p65 were evaluated by Western blot.Results miR-146a expression was significantly decreased in the model group compared with the control group(P＜0.01),while mRNA and protein expression levels of TLR4,MyD88,and TRAF6,and protein expression of p-NF-κB p65,IL-1β,IL-6,and TNF-α were significantly increased(P＜0.01).In contrast,miR-146a expression was significantly increased(P＜0.01)and mRNA and protein expression of TLR4,MyD88,and TRAF6,and p-NF-κB p65 protein expression(P＜0.01),as well as IL-1β,IL-6,and TNF-α levels(P＜0.05)were significantly decreased in the Jiawei Simiao powder and colchicine groups.Conclusions Jiawei Simiao powder may alleviate MSU crystal-induced macrophage inflammatory responses by upregulating miR-146a,suppressing TLR4/NF-κB signaling pathway activation,and decreasing secretion of inflammatory factors.

Traditional Chinese medicine (TCM) serves as a treasure trove of ancient knowledge, holding a crucial position in the medical field. However, the exploration of TCM's extensive information has been hindered by challenges related to data standardization, completeness, and accuracy, primarily due to the decentralized distribution of TCM resources. To address these issues, we developed a platform for TCM knowledge discovery (TCMKD, https://cbcb.cdutcm.edu.cn/TCMKD/). Seven types of data, including syndromes, formulas, Chinese patent drugs (CPDs), Chinese medicinal materials (CMMs), ingredients, targets, and diseases, were manually proofread and consolidated within TCMKD. To strengthen the integration of TCM with modern medicine, TCMKD employs analytical methods such as TCM data mining, enrichment analysis, and network localization and separation. These tools help elucidate the molecular-level commonalities between TCM and contemporary scientific insights. In addition to its analytical capabilities, a quick question and answer (Q&A) system is also embedded within TCMKD to query the database efficiently, thereby improving the interactivity of the platform. The platform also provides a TCM text annotation tool, offering a simple and efficient method for TCM text mining. Overall, TCMKD not only has the potential to become a pivotal repository for TCM, delving into the pharmacological foundations of TCM treatments, but its flexible embedded tools and algorithms can also be applied to the study of other traditional medical systems, extending beyond just TCM.

With reference to the Information and Documentation-Resource Description (GB/T 3792-2021) and Bibliographical Description for Ancient Chinese Books (GB/T 3792.7-2008) and other cataloging standards and rules, drawing on the practical experience of cataloging ancient TCM books, Bibliographical Cataloging for Ancient TCM Books was formulated. This standard specifies the entry items and their order of ancient TCM books, cataloging identifier, cataloging text, cataloging information source, and cataloging item details. The standard can provide standardized and unified guiding principles and methods for the work of ancient TCM books, and promote the sharing and utilization of ancient TCM books.

Objective To find the molecular mechanism underlying the effect of congenital cataract related 129th single-site mutation G129C on the thermal stability of human γC crystallin(HγC)protein structure.Methods HγC-WT and HγC-G129C were expressed and purified in vitro.The changes of intrinsic fluorescence intensity and static light scattering intensity of proteins with temperature were measured,and the temperature dependence of the folding and aggregation structures of HγC-WT and HγC-G129C was compared.Results When temperature was be-low 65 ℃,the barycentric mean of the intrinsic fluorescence of HγC-WT and HγC-G129C shifted towards a longer wavelength and the fluorescence intensity decreased with the increasing temperature,which was believed to be the evidence of unfolded protein conformation.When the temperature was higher than 65 ℃,the static light scattering intensity increased significantly with the temperature,indicating the protein aggregation upon heating.The wild-type HγC-G129C showed a stronger aggregation potency.During the thermal de-naturation process of HγC-WT and HγC-G 129C,the crossing-point temperatures were 74.5 ℃ and 55.5 ℃,respectively.HγC-WT showed higher thermal stability.Conclusions The congenital cataract-associated G129C mutation significantly weakens conforma-tional stability of γC-crystallin.

Objective:To explore the related clinical characteristics of myocardial injury caused by venomous snake bites, and to provide a reference for cardiac protection and treatment in patients with venomous snake bites.Methods:A retrospective analysis was conducted on 294 patients with venomous snake bites admitted to Chongqing Emergency Medical Enter from January 2020 to December 2022. They were divided into the myocardial injury group ( n=90) and the non-myocardial injury group ( n=204) according to the presence or absence of abnormal electrocardiogram or/and cardiac troponin I (cTnI). The research subjects were divided into the mild group ( n=213), the moderate group ( n=57), and the severe group ( n=24) according to the severity of clinical manifestations. The time from bite to admission, laboratory indicators related to myocardial injury, electrocardiogram and echocardiogram of each group were analyzed and compared. Myocardial injury and electrocardiogram manifestations caused by bites from different types of venomous snakes were analyzed. Results:The abnormal electrocardiogram caused by venomous snake bites was mainly manifested as changes in the ST-T segment, and 84 patients showed abnormal electrocardiogram (28.6%). Compared with the non-myocardial injury group, patients in the myocardial injury group were older ( Z=-1.984, P=0.047), the time from bite to admission and the length of hospital stay were longer, and the systolic blood pressure (SBP) and diastolic blood pressure (DBP) were lower (all P<0.05). The levels of cTnI, lactic acid dehydrogenase (LDH), creatine kinase (CK), creatine kinase MB (CK-MB), a-hydroxybutyrate dehydrogenase (a-HBDH), C-reactive protein (CRP), and the ratio of the peak of mitral valve velocity E to the peak of early diastolic velocity e at the annulus (E/e) in the myocardial injury group were higher than those in the non-myocardial injury group (all P<0.05). The left ventricular ejection fraction (LVEF) was lower than that in the non-myocardial injury group ( Z=-3.160, P=0.02). Compared with the mild group, the age of patients in the severe group was significantly older ( P=0.024), and the time from bite to admission was shown as mild group
