Mechanism of Fangji Fulingtang for Treating Acute Kidney Injury Induced by Ischemia-reperfusion Based on Network Pharmacology and Molecular Docking Verification / 中国实验方剂学杂志

ObjectiveTo explore the mechanism of Fangji Fulingtang in the treatment of acute kidney injury （AKI） induced by ischemia-reperfusion based on network pharmacology and experimental verification. MethodActive components of Fangji Fulingtang were retrieved from Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform （TCMSP） and previous report and targets of these components were predicted by SwissTargetPrediction. The targets of AKI were searched from GeneCards， Online Mendelian Inheritance in Man （OMIM）， the database of gene-disease associations （DisGeNET）， and Therapeutic Target Database （TTD）. Protein-protein interaction （PPI） network was constructed by STRING. Metascape was used for Gene Ontology （GO） term enrichment and Kyoto Encyclopedia of Genes and Genomes （KEGG） pathway enrichment of core targets. Cytoscape was employed to construct the "medicinal-active component-target-disease" network and “active component-target-pathway” network. AutoDock was applied for molecular docking. Finally， animal experiment was carried out to validate the mechanism of Fangji Fulingtang in treatment of AKI. ResultA total of 137 active components and 858 targets of Fangji Fulingtang， 1 294 targets of AKI， and 267 targets of Fangji Fulingtang in the treatment of AKI were screened out. Phosphoinositide-3-kinase regulatory subunit 1 （PIK3R1）， phosphatidylinositol-4，5-bisphosphate 3-kinase catalytic subunit alpha （PIK3CA）， proto-oncogene tyrosine protein kinase （SRC）， protein kinase B1 （Akt1）， and mitogen-activated protein kinase 3 （MAPK3） were the key anti-AKI targets of Fangji Fulingtang， which were involved in 1 609 GO terms， particularly cell response to lipids， membrane rafts， and protein kinase activity， and 140 KEGG pathways such as PI3K/Akt signaling pathway， chemokine signaling pathway， and Toll-like receptor signaling pathway. Molecular docking showed that the core active components had strong binding affinity to the key targets. The hematoxylin and eosin （HE） staining results indicated that Fangji Fulingtang can significantly improve the pathological state and the serological results suggested that the levels of serum creatinine （SCr） and blood urea nitrogen （BUN） were significantly reduced. ConclusionThis study clarified the mechanism of Fangji Fulingtang in the treatment of AKI and found that Fangji Fulingtang had the multi-component， multi-target， and multi-pathway characteristics in the treatment of AKI. The result lays a foundation for further study of its specific mechanism.

Development and validation of a prediction model for treatment failure in peritoneal dialysis-associated peritonitis patients: a multicenter study / 南方医科大学学报

OBJECTIVE@#To develop and validate a risk prediction model of treatment failure in patients with peritoneal dialysis-associated peritonitis (PDAP).@*METHODS@#We retrospectively analyzed the data of patients undergoing peritoneal dialysis (PD) in 3 dialysis centers in Jilin Province who developed PDAP between January 1, 2013 and December 31, 2019. The data collected from the Second Hospital of Jilin University and Second Division of First Hospital of Jilin University) were used as the training dataset and those from Jilin Central Hospital as the validation dataset. We developed a nomogram for predicting treatment failure using a logistic regression model with backward elimination. The performance of the nomogram was assessed by analyzing the C-statistic and the calibration plots. We also plotted decision curves to evaluate the clinical efficacy of the nomogram.@*RESULTS@#A total of 977 episodes of PDAP were included in the analysis (625 episodes in the training dataset and 352 episodes in the validation dataset). During follow-up, 78 treatment failures occurred in the training dataset and 35 in the validation dataset. A multivariable logistic regression prediction model was established, and the predictors in the final nomogram model included serum albumin, peritoneal dialysate white cell count on day 5, PD duration, and type of causative organisms. The nomogram showed a good performance in predicting treatment failure, with a C-statistic of 0.827 (95% CI: 0.784-0.871) in the training dataset and of 0.825 (95% CI: 0.743-0.908) in the validation dataset. The nomogram also performed well in calibration in both the training and validation datasets.@*CONCLUSION@#The established nomogram has a good accuracy in estimating the risk of treatment failure in PDAP patients.

Dynamic changes of the PGAM1 expression in the mouse testis exposed to single heat stress / 中华男科学杂志

Objective@#To investigate the expression of phosphoglycerate mutase 1 (PGAM1) in the mouse testis after exposure to single heat stress (SHS).@*METHODS@#We randomly assigned 32 C57 male mice to an SHS (n = 16) and a control group (n = 16), the former bathed in water at 43 ℃ and the latter at 25 ℃ for 15 minutes. At 1 and 7 days after exposure, we harvested the testicular tissue for observation of the morphological changes of testicular cells by HE staining and determination of the location and expression of the PGAM1 protein by immunohistochemistry and Western blot.@*RESULTS@#The testis volume of the mice were reduced significantly, the spermatogenic tubules were disorganized, and the cells were reduced in number after heat stress and basically disappeared after 7 days. Immunohistochemistry showed extensive expression of the PGAM1 protein in the testicular spermatogenic tubules of the SHS-exposed mice, significantly higher than in the control group at 1 day after exposure, which was down-regulated in the testis tissue at 7 days, but still markedly higher than that in the control. Western blot exhibited significantly up-regulated expression of the PGAM1 protein after heat stress compared with that in the control group.@*CONCLUSIONS@#The expression of the PGAM1 protein undergoes dynamic changes in the mouse testis after exposed to single heat stress, which is related to heat stress-induced proliferation and division of testicular spermatogenic cells.

Objective@#To explore the imaging characteristics of large vestibular aqueduct syndrome (LVAS) patients and their relationship with the acoustically evoked short latency negative response (ANSR), so as to provide reference for the diagnosis of LVAS.@*Methods@#Clinical data of 174 patients(334 ears) with LVAS diagnosed and treated by the Department of Otorhinolaryngology Head and Neck Surgery of the First Affiliated Hospital of Guangxi Medical University, from October 2009 to December 2017 were retrospectively analyzed, including 117 males and 57 females, aged from 5 months to 47 years old, with the median age of 4 years and 4 months. ABR and imaging data of patients were collected. Midpoint diameter and the outlet diameter of the vestibular aqueduct were measured on CT images, the midpoint diameter of the intraosseous parts and the extraosseous parts of enlarged endolymphatic sac(EES) were measured on MRI images. The correlation between the above measurements was analyzed by Pearson test using SPSS 17.0. According to whether ASNR was detected in ABR, the above data were divided into two groups, and the differences of the above imaging measurements were compared by the Independent-Sample Test.@*Results@#The average midpoint diameter of the vestibular aqueduct was (1.87±0.58) mm (±s, the following was the same), and the outlet diameter was (3.07±0.99) mm on CT; the average midpoint diameter of the intraosseous parts in enlarged endolymphatic sac(EES) was (2.39±1.37) mm, and the extraosseous parts was (2.50±2.18) mm on MRI. There was a correlation between the four measurements (P<0.05), among which the midpoint diameter of vestibular aqueduct was strongly positively correlated with the outlet diameter (r=0.760), and the remaining pairs were weakly correlated. ASNR was detected in 241 ears (72.16%,241/334) and undetected in 93 ears (27.84%, 93/334) of the 334 ears with LVAS. Midpoint diameter and the outlet diameter of the vestibular aqueduct in no ASNR group were smaller than the ASNR group, and the difference was statistically significant (t value was 2.814 and 2.754, P<0.05). There was no significant difference in the midpoint diameter of the intraosseous parts and the extraosseous parts of enlarged endolymphatic sac between the two groups, and the difference was no statistically significant(t value was 0.101 and 0.683, P>0.05).@*Conclusions@#There is a strong positive correlation between the midpoint diameter of vestibular aqueduct and the outlet diameter in LVAS patients. There is a certain correlation between the size of vestibular aqueduct and the size of endolymphatic sac. The smaller the diameter of vestibular aqueduct, the lower the occurrence rate of ASNR.

Before hemorrhagic shock, and at 30, 60, 90, 120, 180 and 240 h after hemorrhagic shock ( T0?6 ) , blood samples were collected from the femoral artery for determination of plasma tumor necrosis factor?alpha ( TNF?α) , interleukin?6(IL?6), nuclear factor kappa B (NF?κB), S100β protein and neuron?specific enolase (NSE) concentra?tions. After blood sampling at T6 , the animals were sacrificed, and brains were removed for microscopic examination of pathological changes, and for determination of Toll?like receptor 4 ( TLR4) expression by Western blot. Results Compared with group Sham, the plasma NSE, S100β protein, TNF?α, IL?6 and NF?κB concentrations were significantly increased at T2?6 , and TLR4 expression was up?regulated at T6 in HS and Sev groups ( P<0?05) . Compared with group HS, the plasma NSE, and S100βprotein concentra?tions were significantly decreased at T4?6 , the plasma TNF?α, IL?6 and NF?κB concentrations were de?creased at T2?6, and TLR4 expression was down?regulated at T6 (P<0?05), and the pathological changes were significantly attenuated in group Sev. Conclusion Sevoflurane can mitigate brain injury in a pig mod?el of hemorrhagic shock in hypothermia environment, and the mechanism may be related to inhibited TLR4∕NF?κB signaling pathway and attenuated inflammatory responses.

How to improve the diagnosis rate of early gastric cancer in China / 浙江大学学报·医学版

China has great burden of gastric cancer, and the diagnosis rate of early gastric cancer is relatively low (<10%). To perform screening, early endoscopic diagnosis and treatment of gastric cancer in high-risk population is a feasible and efficient way to change the current status. Therefore, the Chinese Society of Digestive Endoscopy recently issued Consensus on screening, "Endoscopic diagnosis and treatment of early gastric cancer screening in China". The consensus suggests a feasible and efficient strategy for early detection of gastric cancer: screening with non-invasive procedures, followed by intensive endoscopic examination for screened high-risk population. In this article, we also describe the current status, the causes, high-risk population and early diagnosis of gastric cancer in China; and review the new development of serology and endoscopic techniques for early diagnosis.

Expression and significance of HSP90 in plasma of patients with multiple myeloma / 中国实验血液学杂志

This study was purposed to investigate the expression of heat shock protein 90 (HSP90) in peripheral blood plasma of patients with multipl myeloma (MM), and to explore its possible role in the pathogenesis of MM, and its relationship with treatment, prognosis and the outcome of patients. The peripheral blood samples from 58 patients with MM and 20 healthy volunteers were collected. The plasma concentration of HSP90 in patients and healthy volunteers was measured by ELISA. The results showed that the concentration of HSP90 in peripheral blood of patients with MM was significantly higher than that in the healthy volunteers [(32.398 ± 3.674) vs (25.762 ± 2.916) ng/ml] (P < 0.001). The concentration of HSP90 showed positively correlation with International Staging System(ISS) stage, therapeutic response, frequency of plasmocyte, globulin, immune globulin, M-protein, β2 micro-globulin, and light chain of MM patients (P < 0.05) ; while it showed little correlation with sex, age and type of MM patients (P > 0.05) . It is concluded that the HSP90 may be involved in the occurrence and development of MM. Detection of HSP90 in plasma would contribute to judge the clinical course, therapeutic efficacy and prognosis of MM patients.
