Chronic atrophic gastritis(CAG)is a common intractable gastric disease in clinic,which belongs to the gastric precancerous lesions.Professor LIU Feng-Bin and his team have performed the exploration and practice in the field of CAG for more than 30 years,and they proposed that the evolution of the traditional Chinse medicine(TCM)pathogenesis of inflammation-to-tumor transition(ITT)in CAG was characterized by spleen deficiency being the root cause,qi stagnation,blood stasis and dampness retention being the branch cause,and stasis and toxin being the aggravating factors.Deificiency of the spleen and stomach is the initial factor of CAG,which influences the whole process of the disease.Qi stagnation,blood stasis and dampness retention are the triggering and aggravating factors for the ITT in CAG.The formation of blood stasis and toxin is the key to the progression and transition of CAG.Treatment of ITT in CAG should be based on the results of syndrome differentiation and gastroscopic findings by staging therapy.Before treatment,disease dianosis and syndrome differentiation should be made,and macro and micro syndrome differentiation should be carried out for assistance.Therapy of strengthening the spleen and supporting healthy qi should be implemented throughout the whole process of the disease.The early stage of CAG has the features of gastric mucosa with mild to moderate atrophy and with or without mild intestinal epithelial hyperplasia,the pathogenesis of early CAG is characterized by weakness of the spleen and stomach and is accompanied with the pathological factors of qi stagnation,damp-retention and blood stasis,and the basic treatment should adopt the therapies of strengthening the spleen and clearing heat,regulating qi and activating blood stasis.The advanced stage of CAG has the features of severe atrophic gastric mucosa with or without moderate to severe intestinal epithelial and/or mild to moderate intraepithelial neoplasia,the pathogenesis is characterized by weakness of the spleen and stomach,phlegm blended with blood stasis,and stasis-toxin in the gastric collaterals,and the basic treatment should adopt the therapies of supporting healthy qi and dissipating masses,and unblocking the collaterals and removing toxin,so as to construct an intact line to blocking the ITT in CAG with traditional Chinese medicine.

Background:
Intrahepatic cholangiocarcinoma (ICC) is a highly desmoplastic tumor with poor prognosis even after curative resection. We investigated the associations between the composition of the ICC stroma and immune cell infiltration and aimed to develop a stromal-immune signature to predict prognosis in surgically treated ICC.
Patients and methods:
We recruited 359 ICC patients and performed immunohistochemistry to detect α-smooth muscle actin (α-SMA), CD3, CD4, CD8, Foxp3, CD68, and CD66b. Aniline was used to stain collagen deposition. Survival analyses were performed to detect prognostic values of these markers. Recursive partitioning for a discrete-time survival tree was applied to define a stromal-immune signature with distinct prognostic value. We delineated an integrated stromal-immune signature based on immune cell subpopulations and stromal composition to distinguish subgroups with different recurrence-free survival (RFS) and overall survival (OS) time.
Results:
We defined four major patterns of ICC stroma composition according to the distributions of α-SMA and collagen: dormant (α-SMAlow/collagenhigh), fibrogenic (α-SMAhigh/collagenhigh), inert (α-SMAlow/collagenlow), and fibrolytic (α-SMAhigh/collagenlow). The stroma types were characterized by distinct patterns of infiltration by immune cells. We divided patients into six classes. Class I, characterized by high CD8 expression and dormant stroma, displayed the longest RFS and OS, whereas Class VI, characterized by low CD8 expression and high CD66b expression, displayed the shortest RFS and OS. The integrated stromal-immune signature was consolidated in a validation cohort.
Conclusion
We developed and validated a stromal-immune signature to predict prognosis in surgically treated ICC. These findings provide new insights into the stromal-immune response to ICC.

Objective:
Emerging evidence suggests that air pollution exposure may increase the risk of Parkinson’s disease (PD). We aimed to investigate the association between exposure to fine particulate matter (PM2.5) and the risk of incident PD nationwide.
Methods:
We utilized data from the Taiwan National Health Insurance Research Database, which is spatiotemporally linked with air quality data from the Taiwan Environmental Protection Administration website. The study population consisted of participants who were followed from the index date (January 1, 2005) until the occurrence of PD or the end of the study period (December 31, 2017). Participants who were diagnosed with PD before the index date were excluded. To evaluate the association between exposure to PM2.5 and incident PD risk, we employed Cox regression to estimate the hazard ratio and 95% confidence interval (CI).
Results:
A total of 454,583 participants were included, with a mean (standard deviation) age of 63.1 (9.9) years and a male proportion of 50%. Over a mean follow-up period of 11.1 (3.6) years, 4% of the participants (n = 18,862) developed PD. We observed a significant positive association between PM2.5 exposure and the risk of PD, with a hazard ratio of 1.22 (95% CI, 1.20–1.23) per interquartile range increase in exposure (10.17 μg/m3) when adjusting for both SO2 and NO2.
Conclusion
We provide further evidence of an association between PM2.5 exposure and the risk of PD. These findings underscore the urgent need for public health policies aimed at reducing ambient air pollution and its potential impact on PD.

Acute kidney injury (AKI) is a common critical disease clinically with high morbility and mortality and some survival patients also progress to chronic kidney disease. Renal ischemia-reperfusion (IR) is one of the main causes of AKI, in which, its repair and potential fibrosis, apoptosis, inflammation and phagocytosis play important roles. During the progression of IR-induced AKI, the expression of erythropoietin homodimer receptor (EPOR)2 and EPOR and β common receptor formed heterodimer receptor (EPOR/βcR) is changed dynamically. Moreover, (EPOR)2 and EPOR/βcR may synergistically participate in renoprotection at the stage of AKI and early repair, whereas at the late stage of AKI, the (EPOR)2 induces renal fibrosis and the EPOR/βcR facilitates repair and remodelling. The underlying mechanism, signaling pathways and the different effect turning point of (EPOR)2 and EPOR/βcR have not been well defined. It has been reported that EPO, according to its 3D structure, derived helix B surface peptide (HBSP) and cyclic HBSP (CHBP) only bind to EPOR/βcR. Synthesized HBSP, therefore, provides an effective tool to distinguish the different roles and mechanisms of both receptors, with the (EPOR)2 promoting fibrosis or the EPOR/βcR leading to repair/remodelling at the late stage of AKI. This review discusses the similarities and differences of (EPOR)2 and EPOR/βcR in their impacts on apoptosis, inflammation and phagocytosis in AKI, repair and fibrosis post IR, associated mechanisms, signaling pathways and outcomes.

Interleukin-1 receptor associated kinase 4 (IRAK-4), acting as a serine threonine kinase, is considered as a key signal node for the transduction of IL-1R family and TLRs signal pathway. Studies have found that IRAK-4 has a hand in many signal pathways, involving the inflammatory response of human joints, intestines, liver and nervous system, as well as other autoimmune diseases. It is also one of the causes of drug resistance of some cancer cells. Therefore, IRAK-4 tends to be an effective therapeutic target for inflammatory diseases and cancer. The prospects for the development of drugs in this pathway is to develop novel IRAK-4 small molecule inhibitors and investigate their safety and effectiveness, enrich the clinical treatment of inflammatory and cancer diseases finally. This paper classified and summarized the latest research progress on small molecule inhibitors of IRAK-4 signaling pathway according to structures of the compounds, in order to provide assistances and references for the research and development of related drugs.
