Research progress of FOXO1 in oral squamous cell carcinoma / 国际肿瘤学杂志

Forkhead box protein O1 (FOXO1) has been extensively studied as a tumor suppressor. In oral squamous cell carcinoma, studies have demonstrated that FOXO1 can inhibit tumor cell oxidative stress, stemness and epithelial-mesenchymal transition, and promote tumor cell autophagy and apoptosis. FOXO1 may serve as a potential target for the treatment of oral squamous cell carcinoma.

Transcriptome sequencing technology and its application in oral diseases, dental implants and regeneration / 中国组织工程研究

BACKGROUND: Since the application of transcriptome sequencing technology has made remarkable achievements in the research of melanoma and breast cancer, transcriptome sequencing technology has become a hot research method in scientific research and widely used in the field of stomatology. OBJECTIVE: To review the development of transcriptome sequencing technology and its application in various disciplines of stomatology through searching, screening and reading literature. METHODS: A search of CNKI, CBM and PubMed was performed for relevant literature published from 2015 through 2020. The search terms were “transcriptome, sequencing technology, RNA-seq, microarray, oral cancers, OSCC, periodontal, caries, pulp disease, tooth development, DPSCs, PDLSCs, orthodontics, implant” in English and Chinese, respectively. According to the inclusion and exclusion criteria, 72 literatures were included to review the development of transcriptome sequencing technology and its application in the field of stomatology. RESULTS AND CONCLUSION: In the development of transcriptome sequencing technology, RNA-seq technology has the greatest advantage in scientific research, because of its high accuracy, high throughput and low price. In the field of stomatology, this technology has been used in the research of oral squamous cell carcinoma, periodontitis, dental pulp disease, tooth regeneration, orthodontics and dental implantation, and has achieved some achievements. However, the current research on the same kind of disease does not reflect the relationship between the various studies, and the research content is limited. It is believed that more discoveries can be yielded in stomatology by exploring the relationship between different studies and expanding the research content.

Research progress of satlnamide in treatment of Parkinson' s diseases / 中国药理学通报

Parkinson's disease (PD) is the second most common chronic progressive neurodegenerative disorder in the elderly after Alzheimer' 8 disease. Over the decadcs, levodopa has been considered the main therapy against PD. However, long term use of levodopa is often accompanicd by adverse reactions, including nausea, insomnia, dyskinesia, and "wetring-off" and " on-o/T" phenomena, ranging in severity from mild and non-disabling to incapacitating. On March 21 2017, US Food and Drug Administration ( FDA ) approved safinamide us an adjunctive treatment to levodopa in patients vilh PD experiencing " off" episodes. As a new drug for the treatment of PD, safinamide has the advantage of high selectivity and safely. This paper reviews the mechanisms and some clinical trials of safinamide.

Comparison of nighttime and daytime operation on outcomes of kidney transplant with deceased donors: a retrospective analysis / 中华医学杂志(英文版)

BACKGROUND@#Kidney transplant is always emergent operations and frequently need to be performed at nighttime to reduce cold ischemia time (CIT). Previous studies have revealed that fatigue and sleep deprivation can result in adverse consequences of medical procedures. This study aimed to evaluate whether nighttime operation has adverse impact on kidney transplant.@*METHODS@#A retrospective analysis of recipients accepted kidney transplant from deceased donors in one center from 2014 to 2016 was performed. Daytime transplant was defined as operation started after 8 AM or ended before 8 PM and nighttime operation was defined as operation ended after 8 PM or started before 8 AM. The incidences of complications such as delayed graft function, acute rejection, surgical complications and nosocomial infections were compared between 2 groups. Student's t-test was used to analyze continuous variables such as serum creatinine (Scr) at 1-year of post-transplant. The Chi-square test was used to analyze categorical variables. Differences in recipients and graft survival were analyzed using Kaplan-Meier methodology and log-rank tests.@*RESULTS@#Among the 443 recipients, 233 (52.6%) were classified into the daytime group and the others 210 (47.4%) were in the nighttime group. The 1-year survival rate of recipients was similar for the recipients in the daytime and nighttime groups (95.3% vs. 95.2%, P = 0.981). Although the 1-year graft survival rate in the nighttime group was slightly superior to that in the daytime group, the difference was not significant (92.4% vs. 88.4%, P = 0.164). Furthermore, Scr and incidence of complications were also not significantly different between the 2 groups.@*CONCLUSIONS@#Our results suggested that operation time of kidney transplant with short CIT has no significant impact on the outcome of kidney transplant. Nighttime operation of kidney transplant with short CIT could be postponed to the following day to alleviate the burden on medical staffs and avoid the potential risk.

Beneficial Effect of Moderately Increasing Hypothermic Machine Perfusion Pressure on Donor after Cardiac Death Renal Transplantation / 中华医学杂志(英文版)

Background@#Vascular resistance and flow rate during hypothermic machine perfusion (HMP) of kidneys is correlated with graft function. We aimed to determine the effects of increasing HMP pressure versus maintaining the initial pressure on kidney transplantation outcomes.@*Methods@#We retrospectively reviewed the data of 76 primary transplantation patients who received HMP-preserved kidneys from 48 donors after cardiac death between September 1, 2013, and August 31, 2015. HMP pressure was increased from 30 to 40 mmHg (1 mmHg = 0.133 kPa) in kidneys with poor flow and/or vascular resistance (increased pressure [IP] group; 36 patients); otherwise, the initial pressure was maintained (constant pressure group; 40 patients). Finally, the clinical characteristics and transplantation outcomes in both groups were assessed.@*Results@#Delayed graft function (DGF) incidence, 1-year allograft, patient survival, kidney function recovery time, and serum creatinine level on day 30 were similar in both groups, with improved flow and resistance in the IP group. Among patients with DGF, kidney function recovery time and DGF duration were ameliorated in the IP group. Multivariate logistic regression analysis revealed that donor hypertension (odds ratio [OR]: 1.43, 95% confidence interval [CI]: 1.02-2.06, P = 0.035), donor terminal serum creatinine (OR: 1.27, 95% CI: 1.06-1.62, P = 0.023), warm ischemic time (OR: 3.45, 95% CI: 1.97-6.37, P = 0.002), and terminal resistance (OR: 3.12, 95% CI: 1.76-6.09, P = 0.012) were independent predictors of DGF. Cox proportional hazards analysis showed that terminal resistance (hazard ratio: 2.06, 95% CI: 1.32-5.16, P = 0.032) significantly affected graft survival.@*Conclusion@#Increased HMP pressure improves graft perfusion but does not affect DGF incidence or 1-year graft survival.

Inhibitory effect of extratable petroleum ether of Polyrhachis vicina Roger on neuroinflammatory response in depressed rats / 药学学报

The main ingredient of extractable petroleum ether of Polyrhachis vicina Roger (EPPR) is octadecene unsaturated fatty acids. Mounting evidence supports that N-3 polyunsaturated fatty acids can attenuate neuroinflammation, reduce oxidative stress, then protect neurons. In order to explore the effect of EPPR on the inflammatory response of depressed rats, the model of depression was established by chronic unpredictable mild stress (CUMS). Sucrose preference test, forced swimming test were employed to investigate the anti-depressive effect of EPPR in rat. The activation of glial cells and astrocytes in the prefrontal cortex of depressed rats was observed by immunofluorescence. The levels of inflammatory factors were measured by Quantitative Real-time PCR. NF-κB was detected by immunoblotting. EPPR could significantly improve the depressive behavior of rats, decrease NF-κB translocation to the compartment of nucleus, down-regulate the pro-inflammatory cytokines IL-1β, TNF-α and indoleamine 2,3-dioxygenase (IDO) gene expression levels, inhibit the activation of microglia and astrocytes in depressed rats. These results suggest that EPPR could notably ameliorate inflammation induced by chronic stress, and the protective effect might be linked to the regulation of NF-κB p65.

Advances in immunotherapy of Alzheimer's disease with traditional Chinese medicine / 药学学报

Alzheimer's disease (AD) is a type of common neurodegenerative disease. The main clinical symptom of the disease is progressive cognitive dysfunction, which has no effective therapy yet. With the in-depth immunology study in the central nervous system, studies in different fields such as preclinical phase, genetics and bioinformatics have shown that immune dysfunction contribute to the pathogenesis of AD, including the beginning, maintenance and deterioration stage in AD. China has a wealth of natural medicine resources and clinical experiences. A large number of natural drugs and effective components both can regulate the immune function and ameliorate the symptoms in AD. This review summarizes the researches of ameliorating the symptoms in AD through immunization regulation in recent years with an aim to provide new ideas and clues in the study of new anti-AD drugs using natural medicines.
