Signal mining and analysis of adverse events of oseltamivir，zanamivir and baloxavir marboxil / 中国药房

OBJECTIVE To provide reference for safe drug use in clinic by mining the adverse drug events （ADE） of 3 kinds of anti-influenza A virus drugs （oseltamivir， zanamivir， baloxavir marboxil）. METHODS The ADE data of oseltamivir， zanamivir and baloxavir marboxil were collected from the FDA adverse event reporting system （FAERS） between the first quarter in 2004 and the third quarter in 2022， and mined by using reporting odds ratio （ROR） method. The designated medical events （DME） were estimated. The system organ class （SOC） in the Medical Dictionary for Regulatory Activities （MedDRA， version 25.0） was used for the classification and statistics of drug ADE terminology. RESULTS A total of 12 636， 1 749 and 1 283 ADE reports were retrieved for oseltamivir， zanamivir and baloxavir marboxil， involving 26， 16 and 17 SOCs， respectively. Oseltamivir was strongly associated with sleep terror， abnormal behavior， hallucination and delirium. Zanamivir was implicated in abnormal behavior， delirium， incoherence， and altered state of consciousness with prominent signal intensity. Baloxavir marboxil was strongly associated with ischemic colitis， hemorrhagic cystitis， erythema multiforme and melaena. Erythema multiform was detected in the DME of three drugs with strong signals. CONCLUSIONS When clinically administering the three drugs， it is crucial to pay close attention to both common adverse reactions and those ADEs that are not explicitly mentioned in the drug instructions. For oseltamivir， clinicians should exercise caution due to the potential risk of acute kidney injury and fulminant hepatitis， necessitating regular monitoring of the patient’s liver and kidney function. When prescribing zanamivir， caution should be exercised due to ADEs related to the respiratory system， including acute respiratory distress syndrome and respiratory failure， necessitating close monitoring of the patient’s respiratory status. Similarly， for baloxavir marboxil， clinicians should be vigilant for potential ADEs such as erythema multiforme and rhabdomyolysis.

PRMT6 promotes tumorigenicity and cisplatin response of lung cancer through triggering 6PGD/ENO1 mediated cell metabolism

Metabolic reprogramming is a hallmark of cancer, including lung cancer. However, the exact underlying mechanism and therapeutic potential are largely unknown. Here we report that protein arginine methyltransferase 6 (PRMT6) is highly expressed in lung cancer and is required for cell metabolism, tumorigenicity, and cisplatin response of lung cancer. PRMT6 regulated the oxidative pentose phosphate pathway (PPP) flux and glycolysis pathway in human lung cancer by increasing the activity of 6-phospho-gluconate dehydrogenase (6PGD) and α-enolase (ENO1). Furthermore, PRMT6 methylated R324 of 6PGD to enhancing its activity; while methylation at R9 and R372 of ENO1 promotes formation of active ENO1 dimers and 2-phosphoglycerate (2-PG) binding to ENO1, respectively. Lastly, targeting PRMT6 blocked the oxidative PPP flux, glycolysis pathway, and tumor growth, as well as enhanced the anti-tumor effects of cisplatin in lung cancer. Together, this study demonstrates that PRMT6 acts as a post-translational modification (PTM) regulator of glucose metabolism, which leads to the pathogenesis of lung cancer. It was proven that the PRMT6-6PGD/ENO1 regulatory axis is an important determinant of carcinogenesis and may become a promising cancer therapeutic strategy.

Distribution of monocyte subsets and their surface CD31 intensity are associated with disease course and severity of hemorrhagic fever with renal syndrome / 细胞与分子免疫学杂志

Objective To investigate the relationship between disease courses and severity and monocyte subsets distribution and surface CD31 intensity in patients of hemorrhagic fever with renal syndrome (HFRS). Methods Peripheral blood samples from 29 HFRS patients and 13 normal controls were collected. The dynamic changes of classical monocyte subsets (CD14++CD16-), intermediated monocyte subsets (CD14++CD16+) and non-classical monocyte subsets (CD14+CD16++) and the mean fluorescent intensity (MFI) of CD31 on monocyte subsets were detected by multiple-immunofluorescent staining and flow cytometry. Results In acute phase of HFRS, the ratio of classical monocyte subsets to total monocytes was dramatically decreased compared to convalescent phase and normal control. It was still much lower in convalescent phase compared to normal controls. The ratio of classical monocyte subsets to total monocytes were decreased in HFRS patients compared to that in normal control, whereas there was no difference between severe/critical groups and mild/moderate groups. On the contrary, the ratio of intermediate monocyte subsets to total monocytes in acute phase of HFRS was significantly increased compared to convalescent phase and normal control. The ratio of intermediate monocyte subsets to total monocytes were increased in HFRS patients compared to that in normal control, whereas no difference was found between severe/critical groups and mild/moderate groups. Phases or severity groups had no difference in ratio of non-classical monocyte subsets to total monocytes. Additionally, the ratio of classical monocyte subsets had a tendency to decline and that of intermediate monocyte subsets showed an increase both to total monocytes between the acute and convalescent phases in 11 HFRS patients with paired-samples. Moreover, in acute phase of HFRS, the mean fluorescent intensity (MFI) of CD31 on three monocyte subsets all decreased, specifically classical monocyte subsets showed the highest MFI of CD31 while the normal control reported the highest MFI of CD31 in non-classical monocyte subsets. In convalescent phase, the MFI of CD31 on classical and intermediated monocyte subsets were both lower than that of normal control, while MFI of CD31 was still significantly lower than normal control on non-classical monocyte subsets. Finally, MFI of CD31 on classical and intermediated monocyte subsets in severe/critical group were both lower than those in mild/moderate group, showing no statistical difference in MFI of CD31 on non-classical monocyte subset across groups of different disease severity. Conclusion The ratio of classical and intermediated monocyte subsets to total monocytes are correlated with the course of HFRS, and so are the surface intensity of CD31 on these monocyte subsets with the disease course and severity. The surface intensity of CD31 on non-classical monocyte subsets, however, is correlated only with the course of the disease. Together, the underlying mechanisms for the observed changes in monocyte subsets in HFRS patients should be further investigated.

Research on Tongue Color Classification in Traditional Chinese Medicine with Noisy Labels based on Regional Attention Mechanism / 世界科学技术-中医药现代化

Objective Because there are often noisy labels in tongue color labeled samples,these noise samples will lead to the low performance and poor generalization ability of tongue color classification.Mining and establishing an automatic and accurate tongue color classification model to promote the objectification of tongue diagnosis in Traditional Chinese Medicine(TCM).Methods Based on the characteristics of tongue color classification in TCM,this paper proposes a tongue color classification method with noisy labels based on regional attention mechanism.The novelty of the proposed method includes:on the one hand,according to the tongue diagnosis habit of TCM doctors,a tongue color regional attention mechanism is proposed to enhance the feature extraction capability of the network for the tongue color regions such as tip and both sides of the tongue and suppress irrelevant feature channels of other regions.On the other hand,a symmetric modified cross-entropy loss function is designed to optimize the network training,suppressing the impact of noisy labels on the classification performance.Results The classification results on the three self-established tongue color classification datasets show that the accuracy reaches 94.96%,93.36%and 93.92%respectively,the mAP reaches 94.53%,93.05%and 93.38%respectively,the Macro-F1 reaches 94.67%,93.16%and 92.43%respectively.Conclusion The proposed tongue color classification method can significantly improve the classification accuracy with low model complexity,and improve the classification robustness in the case of noisy labels.

Glutaredoxin-1 alleviates acetaminophen-induced liver injury by decreasing its toxic metabolites / 药物分析学报

Excessive N-acetyl-p-benzoquinone imine(NAPQI)formation is a starting event that triggers oxidative stress and subsequent hepatocyte necrosis in acetaminophen(APAP)overdose caused acute liver failure(ALF).S-glutathionylation is a reversible redox post-translational modification and a prospective mechanism of APAP hepatotoxicity.Glutaredoxin-1(Glrx1),a glutathione-specific thioltransferase,is a primary enzyme to catalyze deglutathionylation.The objective of this study was to explored whether and how Glrx1 is associated with the development of ALF induced by APAP.The Glrx1 knockout mice(Glrx1-/-)and liver-specific overexpression of Glrx1(AAV8-Glrx1)mice were produced and underwent APAP-induced ALF.Pirfenidone(PFD),a potential inducer of Glrx1,was administrated preceding APAP to assess its protective effects.Our results revealed that the hepatic total protein S-glutathionylation(PSSG)increased and the Glrx1 level reduced in mice after APAP toxicity.Glrx1-/- mice were more sensitive to APAP overdose,with higher oxidative stress and more toxic metabolites of APAP.This was attributed to Glrx1 deficiency increasing the total hepatic PSSG and the S-glutathionylation of cytochrome p450 3a 11(Cyp3a11),which likely increased the activity of Cyp3a11.Conversely,AAV8-Glrx1 mice were defended against liver damage caused by APAP overdose by inhibiting the S-glutathionylation and activity of Cyp3a11,which reduced the toxic metabolites of APAP and oxidative stress.PFD precede administration upregulated Glrx1 expression and alleviated APAP-induced ALF by decreasing oxidative stress.We have identified the function of Glrx1 mediated PSSG in liver injury caused by APAP overdose.Increasing Glrx1 expression may be investigated for the medical treatment of APAP-caused hepatic injury.

Paraquat causes Alzheimer's-like pathology in rats through Wnt/β-catenin signaling-mediated Aβ production / 中国现代医生

Objective The annual incidence of Alzheimer's disease in China is increasing year by year.The herbicide paraquat widely used in early China may be the factor inducing Alzheimer's disease.This study intends to analyze the mechanism of inducing Alzheimer's disease by constructing an animal model of paraquat poisoning.Methods SD rats were fed paraquat,and the integrity of blood-brain barrier was observed by Evans blue staining.The expression level of Aβ42 in brain tissue was detected by Western-blot,and the expression levels of inflammatory cytokines interleukin-1β,tumor necrosis factor-α and inducible isoform of nitric oxide synthase were detected by ELISA.Results Paraquat could significantly increase the expression level of Aβ42 in brain tissue,destroy the integrity of blood-brain barrier,and increase the expression level of GSK-3β in blood-brain barrier.Further results showed that the use of GSK-3β inhibitors significantly alleviated paraquat induced blood-brain barrier damage and Aβ42 levels.Conclusion Paraquat can damage the integrity of the blood-brain barrier by up-regulating GSK-3β,and eventually lead to paraquat entering the brain,which increases the expression level of Aβ42.

OBJECTIVE To provide a reference for safe drug use in clinic. METHODS ADE reports related to nilotinib from the first quarter of 2007 to the fourth quarter of 2022 were collected from the US FDA adverse event reporting system database. The reporting odds ratio （ROR） and proportional reporting ratio （PRR） of disproportionality measures were used to mine potential ADE signals，which were compared with drug instruction and related case report， and were screened and analyzed according to the designated medical events （DME） list formulated by the European Medicines Agency. RESULTS Totally 23 332 cases of ADE with nilotinib as the primary suspected drug were reported. A total of 359 positive signals were obtained，involving 24 system organ classes （SOC），mainly concentrated in various examinations，heart organ diseases，vascular and lymphatic diseases，all kinds of nervous system diseases，etc. Among them，ADEs such as vertebral artery stenosis，coronary artery stenosis，arterial disease，liver infection and the second primary malignant tumor were not mentioned in the instructions. Seven DMEs were detected，of which bone marrow failure，pulmonary hypertension and deafness were not mentioned in the drug instruction. CONCLUSIONS The common ADE signals of nilotinib excavated in this study are consistent with the instructions. In clinical use，special attention should be paid to DME not mentioned in the instructions such as bone marrow failure，pulmonary hypertension and deafness； cardiac function， blood glucose and blood lipid indexes should be monitored closely.

Exploring the miRNA-mRNA regulatory network in schizophrenia based on GEO database / 四川精神卫生

ObjectiveTo provide a new idea for exploring the molecular genetic approach to the pathogenesis of schizophrenia via construction of microRNA-messenger RNA （miRNA-mRNA） regulatory network in schizophrenia. MethodsThe microarray datasets of GSE54578 miRNA expression profiles in peripheral blood and GSE145554 mRNA expression in the anterior cingulate in postmortem brain of schizophrenic subjects were downloaded from Gene Expression Omnibus （GEO） database since July 2021. The GEO2R was used to identify the differentially expressed miRNAs and mRNAs， screen the miRNA with target differentially expressed mRNA， and predict their potential upstream transcription factors. The overlapping genes from the mRNA targeted by the differentially expressed miRNA and the mRNA differentially expressed in GSE145554 dataset were collected. Then the biological features of hub genes were analyzed via Gene Ontology （GO） analysis and Kyoto Encyclopedia of Genes and Genomes （KEGG） pathway enrichment analysis， and the protein-protein interaction （PPI） network and miRNA-mRNA regulatory network of hub genes were constructed. ResultsA total of 8 up-regulated differentially expressed miRNAs with targeted mRNA were screened out in GSE54578 datasets regarding schizophrenia， which involved in the regulation of 10 transcription factors， 247 down-regulated differentially expressed mRNAs were screened out in GSE145554 datasets， and 17 overlapping mRNAs were obtained. GO analysis showed that the target mRNAs were mainly involved in astrocyte differentiation and development. KEGG pathway enrichment analysis showed that the target mRNAs were mainly involved in Rap1 and Ras signaling pathways. PPI network analysis showed that the mRNAs （KRAS and CD28） might be key genes in schizophrenia. ConclusionThe integrated bioinformatics analysis based on GEO database can identify potential susceptibility genes in schizophrenia， and it also contributes to the construction of miRNA-mRNA regulatory network in schizophrenia.

Effect of rumination on suicide attempts in adolescents with depressive disorder / 中华行为医学与脑科学杂志

Objective:To explore the relationship between rumination and depression and suicide attempts, and the mediating effect of rumination between depression and suicide attempts in adolescents with depressive disorder.Methods:Clinical interviews and questionnaires were conducted on 331 adolescents aged 11-18 with depressive disorders.Depressive symptoms were assessed with patient health questionnaire-9 (PHQ-9). Rumination was assessed with ruminative responses scale-10 (RRS-10), and Chinese version of the sociality module of MINI5.0 was used to assess suicide.SPSS 23.0 software was applied to descriptive statistics, Chi-square test, t-test, Spearman correlation analysis and hierarchical regression analysis, and the SPSS macro program PROCESS V 3.4 was used for Bootstrap mediating effect. Results:The incidence of suicide attempts in adolescents with depressive disorder was 53.78%, which was significantly higher in girls (59.48%) than that in boys (40.40%), and the difference was significant ( χ2=10.16, P<0.01). In contrast to the non-suicide attempt group, suicide attempt group had higher scores on PHQ-9((11.08±9.26) vs (14.43±7.49), t=-3.634, P<0.01), brooding ((10.76±3.89) vs (12.44±3.87), t=-3.926, P<0.01), reflection ((10.05±3.54) vs (11.20±3.33), t=-3.044, P<0.01) and rumination total score ((20.81±6.78) vs (23.64±6.42), t=-3.898, P<0.01). Regression analysis revealed that girl ( β=0.175, t=3.228, P=0.001), depressive symptoms ( β=0.168, t=3.082, P=0.002), rumination ( β=0.138, t=2.364, P=0.019) were risk factors for suicide attempts.Rumination played a complete mediating effect between depressive symptoms and suicide attempts (effect value=0.013, 95% CI=0.003-0.027). Depression symptoms significantly and positively predicted rumination ( P<0.01), and rumination significantly and positively predicted suicide attempts ( P<0.05). Conclusion:The incidence of suicide attempts was high in adolescents with depressive disorders.Depressive symptoms affect suicide attempts mainly through rumination.Clinicians should assess the rumination of adolescents with depressive disorders.In addition, clinicians should implement concurrent psychotherapy to adjust the cognitive response and reduce rumination, in order to improve the mental health and reduce suicide attempts.

Can nanoparticles and nano‒protein interactions bring a bright future for insulin delivery?

Insulin therapy plays an essential role in the treatment of diabetes mellitus. However, frequent injections required to effectively control the glycemic levels lead to substantial inconvenience and low patient compliance. In order to improve insulin delivery, many efforts have been made, such as developing the nanoparticles (NPs)-based release systems and oral insulin. Although some improvements have been achieved, the ultimate results are still unsatisfying and none of insulin-loaded NPs systems have been approved for clinical use so far. Recently, nano‒protein interactions and protein corona formation have drawn much attention due to their negative influence on the

All patients were followed up for 12 months after treatment.The differences of BCVA ,CMT,QOL,clinical efficacy and complications between the two groups were compared.Results BCVA was significantly increased and CMT was significantly decreased in the two groups after treatment,and BCVA was higher in the study group at 9 months [(0.55 ± 0.11) vs.(0.51 ±0.15)],12 months [(0.59 ±0.21) vs.(0.53 ±0.11)] after treatment compared with the control group(t＝2.634,3.010,all P＜0.05),and CMT was lower in the study group at 1－12 months after treatment(t＝5.321, 20.035,25.593,22.456,26.326,27.005,all P＜0.05).At the last follow－up,the distant vision,regulating ability, reading and fine work scores in the study group were (55.27 ±8.24) points,(30.21 ±5.20) points,(20.15 ± 5.01)points,(47.02 ±12.34) points,respectively, which were better than those in the control group [( 50.21 ± 6.35)points,(25.34 ±4.17)points,(16.24 ±3.27)points,(40.25 ±9.25) points](t＝6.352,5.324,6.392,8.251, all P＜0.05).The total effective rate of the study group [88.00%(132／150)] was higher than that of the control group[76.67%(115／150)](χ2 ＝6.623,P＜0.05).There were no serious complications in the two groups.Conclusion Conbercept injection can significantly improve the eyesight of exudative AMD patients ,improve the quality of life,it is safe and reliable,and its treatment effect for AMD is better than traditional conservative treatment .

Effect of subventricular zone invasion on prognosis of glioma patients / 中国肿瘤临床

This work was supported by Science and Technology Program of Health and Family Planning Commission of Jiangxi Province (No.20161106) Abstract Objective: To investigate the prognostic value of subventricular zone (SVZ) invasion in glioma patients. Methods: The clini-cal data of 175 patients with glioma diagnosed based on pathology in Jiangxi Province Cancer hospital between January 2010 and July 2015 were analyzed retrospectively. There were 59 cases of World Health Organization (WHO) gradeⅡ, 59 cases of WHO gradeⅢ, and 57 cases of WHO gradeⅣat the first diagnosis. There were 75 cases of SVZ invasion (SVZ+) and 100 cases of SVZ non-invasion (SVZ-) according to preoperative magnetic resonance imaging. The survival outcomes of both cohorts were compared using the Log-rank test. The correlation between the recurrence pattern and SVZ involvement was analyzed using Chi-square tests. Results: The me-dian follow-up time was 63 months. The 5-year overall survival (OS) and progression-free survival (PFS) rates were 42.2% and 37.5%, respectively. These were 20.9% and 15.3% in the SVZ+group, compared with 57.1% and 44.1% in the SVZ-group, respectively (P<0.001 and P<0.001, respectively). The SVZ+group had fewer cases of total resection, larger lesions (maximum diameter greater than 5.0 cm), and more cases of gradeⅣ(P<0.001, P<0.001, and P=0.018, respectively). There were 89 cases of recurrence. The total recur-rence rate was 62.7% in the SVZ+group, compared with 42.0% in the SVZ-group (P=0.007); the distant recurrence rates were 21.3% and 7.0% (P=0.004), respectively. Conclusions: SVZ invasion is a poor prognostic factor for OS and PFS in gliomas, which is positively correlated with a low total resection rate, large lesions, and gradeⅣlesions, and increases the probability of total recurrence and dis-tant recurrence.
