Phytochemical interventions for post-traumatic stress disorder: A cluster co-occurrence network analysis using CiteSpace / 中西医结合学报

OBJECTIVE@#This study investigated trends in the study of phytochemical treatment of post-traumatic stress disorder (PTSD).@*METHODS@#The Web of Science database (2007-2022) was searched using the search terms "phytochemicals" and "PTSD," and relevant literature was compiled. Network clustering co-occurrence analysis and qualitative narrative review were conducted.@*RESULTS@#Three hundred and one articles were included in the analysis of published research, which has surged since 2015 with nearly half of all relevant articles coming from North America. The category is dominated by neuroscience and neurology, with two journals, Addictive Behaviors and Drug and Alcohol Dependence, publishing the greatest number of papers on these topics. Most studies focused on psychedelic intervention for PTSD. Three timelines show an "ebb and flow" phenomenon between "substance use/marijuana abuse" and "psychedelic medicine/medicinal cannabis." Other phytochemicals account for a small proportion of the research and focus on topics like neurosteroid turnover, serotonin levels, and brain-derived neurotrophic factor expression.@*CONCLUSION@#Research on phytochemicals and PTSD is unevenly distributed across countries/regions, disciplines, and journals. Since 2015, the research paradigm shifted to constitute the mainstream of psychedelic research thus far, leading to the exploration of botanical active ingredients and molecular mechanisms. Other studies focus on anti-oxidative stress and anti-inflammation. Please cite this article as: Gao B, Qu YC, Cai MY, Zhang YY, Lu HT, Li HX, Tang YX, Shen H.

Hot topics in perioperative immune combination therapy for liver cancer / 中华肝胆外科杂志

Most patients with primary hepatocellular carcinoma (HCC) are already in advanced stage when they are diagnosed, with a short survival period and an extremely poor prognosis. HCC seriously threatens the life and health of Chinese people. In recent years, breakthroughs have been made in systemic treatment of HCC, especially in immunotherapy represented by immune checkpoint inhibitors, which has broken the single therapy situation of molecular targeted drugs. And the strategy of immunotherapy combined with anti-angiogenic therapy has shown superiority and profoundly changed the treatment strategy of HCC. This article focuses on several hotspots of immune checkpoint inhibitors combined with anti-angiogenic targeted drugs in the perioperative scenario of HCC, and takes stock of the latest research progress of immunotherapy combined with anti-angiogenic drugs regimens in the perioperative application of HCC.

To study the extent of lymph mode dissection and prognostic factors in patients with intrahepatic cholangiocarcinoma / 中华肝胆外科杂志

Objective:To study the impact of patients with intrahepatic cholangiocellular carcinoma (ICC) who underwent surgical resection with or without lymph node dissection (LND), negative or positive lymph node metastasis detected by LND, different extents of LND, and prognostic factors on long-term prognosis of these patients.Methods:The clinical data of 162 patients who were admitted to the Affiliated Cancer Hospital of Zhengzhou University from June 2014 to October 2019 and underwent surgical resection with postoperative histopathological results confirming ICC were retrospectively analyzed. According to the degree of LND, these patients were divided into three groups: the undissected group ( n=68), N0 dissected group (prophylactic dissection) ( n=41) and N1 dissected group (positive dissection, n=53). Of 94 patients who underwent LND, 23 patients underwernt the first station LND (the routine dissection group, n=23), and 71 patients underwent extended LND (the extended dissection group, n=71). The Kaplan-Meier method was used to construct survival curves. Cox regression analysis was used to detect independent factors affecting survival and long-term prognosis of patients. Results:In this study, there were 87 males and 75 females, with a median age of 60 years.The median survival time of these 162 ICC patients was 10 months. The cumulative survival rates at 1-, 3- and 5-year after surgery were 37.6%, 16.5% and 7.9%, respectively. The 1-, 3- and 5-year cumulative survival rates of the N0 dissection group were 52.1%, 31.7% and 25.4%, respectively, which were significantly better than those of the undissected group (34.2%, 12.7%, 3.4%), and the N1 dissection group (30.3%, 11.4%, 0) ( P<0.05). There were no significant differences in postoperative survival between the extended dissection group and the routine dissection group ( P>0.05). Preoperative CA19-9 >50 U/ml ( RR=1.425, 95% CI: 0.962-2.112), maximum tumor diameter > 5 cm ( RR=0.672, 95% CI: 0.456-0.989), without LND ( RR=1.715, 95% CI: 1.140-2.580), positive margin ( RR=0.591, 95% CI: 0.390-0.897), and without postoperative adjuvant therapy ( RR=0.663, 95% CI: 0.504-0.872) were independent risk factors affecting postoperative survival ( P<0.05). Conclusions:LND in ICC patients improved long-term survival outcomes. However, extended LND did not improve prognosis of these patients. The preoperative CA19-9 level, maximum tumor diameter, lymph node dissection, surgical margin status, and postoperative adjuvant therapy were independent risk factors affecting long-term prognosis of these patients.

Numbers of positive lymph nodes predict postoperative survival of intrahepatic cholangiocellular carcinoma patients after radical resection / 中华普通外科杂志

Objective:To evaluate prognostic significance of metastated lymph nodes (LN) in patients with intrahepatic cholangio carcinoma (ICC) after radical resection.Methods:Data were reviewed on 90 patients at Department of Hepatobiliary and Pancreatic Surgery in our hospital from Feb 2013 to Oct 2019, 37 cases had no LN metastasis (N0 group), 21 cases were in N1 group (positive LN<3) and 32 cases in N2 group (positive LN≥3),and Kaplan-Meier method was used to construct survival curve. Univariate and multivariate COX regression analysis was used to screen independent risk factors.Results:In N0 group the 1-and 3-year survival rates were 57.7% and 35.2%, respectively. In N1 group the 1-and 3-year survival rates were 46.7% and 17.5%, respectively in N2 group. the 1-and 3-year survival rates were 19.6% and 0, respectively. There was statistical significance in overall survival rate among the three groups ( χ2=15.272, P<0.05). Multivariate analysis showed that resection margin ( P=0.009) and the number of positive LN ( P=0.002) were independent risk factors affecting the prognosis of patients. Conclusion:Resection margin and the number of metastasing LN were closely related to postoperative prognosis of ICC patients.

Neuronal Functions of ESCRTs

The endosomal sorting complexes required for transport (ESCRTs) regulate protein trafficking from endosomes to lysosomes. Recent studies have shown that ESCRTs are involved in various cellular processes, including membrane scission, microRNA function, viral budding, and the autophagy pathway in many tissues, including the nervous system. Indeed, dysfunctional ESCRTs are associated with neurodegeneration. However, it remains largely elusive how ESCRTs act in post-mitotic neurons, a highly specialized cell type that requires dynamic changes in neuronal structures and signaling for proper function. This review focuses on our current understandings of the functions of ESCRTs in neuronal morphology, synaptic plasticity, and neurodegenerative diseases.
