RESUMO

@#The rapid advances in technology and medicine have greatly facilitated the application of ionizing radiation. Clinically, radiotherapy is one of the major treatments for malignant tumors. However, besides killing tumor cells, ionizing radiation inevitably leads to radiation damage and even death of normal cells. How ionizing radiation causes cell death and the forms of cell death have always been important research topics in this field. Recently, several forms of cell death induced by irradiation have been discovered. Apart from apoptosis, pyroptosis, necroptosis, ferroptosis, autophagic cell death, and methuosis have gradually become research hotspots, and provide new targets for the development of radioprotective drugs and radiosensitizers. In this review, we summarize various forms of ionizing radiation-induced cell death and related molecular mechanisms. We also introduce the latest progress in radiation protection and radiosensitization based on these cell death mechanisms. This review will provide a reference for the research and development of radioprotective drugs and radiosensitizers in the future.

RESUMO

OBJECTIVE@#To explore whether the characteristic responses to sound stimulations of the auditory neurons in the striatum is regulated in different behavioral states.@*METHODS@#The auditory neurons in the striatum of awake C57BL/6J mice were selected for this study. We recorded the auditory response of the striatum to noises over a long period of time by building a synchronous in vivo electrophysiological and locomotion recording system and using glass microelectrode attachment recording. By analyzing the running speed of the mice, the behavioral states of the mice were divided into the quiet state and the active state, and the spontaneous activity and evoked responses of the auditory neurons in the striatum were analyzed in these two states.@*RESULTS@#Compared with those recorded in the quiet state, the spontaneous activity of the auditory neurons in the striatum of the mice increased significantly (37.06±12.02 vs 18.51±10.91, P < 0.001) while the auditory response of the neurons decreased significantly (noise intensity=60 dB, 3.45±2.99 vs 3.04±2.76, P < 0.001) in the active state.@*CONCLUSION@#Locomotion has a significant inhibitory effect on the auditory response of the striatum, which may importantly contribute to the decline of sound information recognition ability in the active state.

RESUMO

Objective:To explore the value of Neoseq in screening and diagnosis of neonatal fatty acid oxidation disorders (FAOD).Methods:A retrospective case-control study was conducted on 163 500 live births in Changzhou city from April 2015 to April 2021. The following two models were adopted for FAOD screening and diagnosis. (1) Traditional mode: Heel blood samples were obtained from all subjects for initial screening using tandem mass spectrum (TMS), followed by next-generation sequencing (NGS) and other differential diagnostic testings for those with positive results. (2) Neoseq: Neoseq was performed on the true positive, negative and false positive cases according to the traditional mode screening results. The detection rate, additional discovery, reporting period, and other parameters of the two models for FAOD were described and compared.Results:(1) Detection and diagnosis of FAOD: A total of 18 confirmed cases of FAOD were detected through the traditional model, with an incidence of 1/9 083 in Changzhou city. The positive rate was 0.55% (907/163 500) for initial TMS and 0.04% (73/163 500) for the second. The positive predictive value was 2.0%(18/907), with a false positive rate of 98%(889/907) in the initial screening. (2) The results of Neoseq: ①Pathogenic mutations were detected in 16 of the 18 confirmed cases, and the coincidence rate of mutation sites between the two methods was 16/18. The other two confirmed cases were missed diagnosed by Neoseq, including one β-ketothiolase deficiency with only one detected pathogenic mutation and one medium-chain acyl-CoA dehydrogenase deficiency without any detected pathogenic mutation. ②No pathogenic mutations were detected in the 57 false-positive cases by Neoseq. ③Among the 100 negative cases in initial screening, DUOX2 heterozygous mutation, and MTTL1 hemizygous mutation were detected in one case each. ④The median period of results reporting was 43.5 d (28-104 d) for the traditional mode and 12 d (10-15 d) for the Neoseq mode. Conclusions:Neoseq has a high detection rate for FAOD. Combined with TMS screening, Neoseq reduces the false-positive rate of biochemical screening, rapidly identifies genetic causes by shortening the results waiting time and covers diseases that couldn't be detected by traditional biochemical methods.

RESUMO

Aim To evaluate the therapeutic effect of apigenin on liver fibrosis in mice anrl the pharmacologi¬cal mechanism.Methods Carbon tetrachloride ( CC14) -induced liver fibrosis mouse model was estab¬lished.The mice were divided into six groups of con¬trol, model, silibinin(55 mg • kg 1 • d 1 ) , apigenin in high dosage (60 mg • kg 1 • d 1 ) , apigenin in mid¬dle dosage( 30 mg • kg 1 • d 1 ) and apigenin in low dosage( 15 mg • kg 1 • d 1 ).The general life status, body weight and liver coefficient of the mice in every group were recorded.HE staining, Masson staining, immunohistochemistry and Western blot were used to e- valuate the effect of apigenin on the pathological chan¬ges, the markers related to epithelial-mesenchymal transition and signaling pathways of liver tissues.Re¬sults In CCI4-induced liver fibrosis mice, middle and high-dosage of apigenin could improve the general life status, increase body weight, decrease liver coeffi¬ cient, and significantly improve liver lesions.Middle and high-dosage of apigenin significantly increased the expression of the epithelial marker protein E-cadherin and significantly decreased the expression of the mes¬enchymal marker protein Vimentin in liver tissues of mice with the disease.The further results showed that middle and high-dosage apigenin could significantly in¬hibit the expression of phosphorvlated PDK1 and phos- phorvlated AKT protein in liver tissues of model mice.Conclusions Apigenin can inhibit EMT by inhibiting PDK1/AKT signaling pathway, which plays an anti-fi- brosis role.The apigenin has the potential to be further developed as a drug to protect the liver and treat liver fibrosis.

RESUMO

Objective: To compare the impact of bicuspid aortic valve (BAV) or tricuspid aortic valve (TAV) on hemodynamics and left ventricular reverse remodeling after transcatheter aortic valve replacement (TAVR). Methods: We retrospectively analyzed the clinical data of patients who underwent TAVR in our hospital from January 2019 to March 2021. Patients were divided into BAV group and TAV group according to aortic contrast-enhanced CT. Each patient was followed up by N-terminal pro B-type natriuretic peptide (NT-proBNP) and echocardiography at four time points, namely before TAVR, 24 hours, 1 month and 6 months after TAVR. Echocardiographic data, including mean pressure gradient (MPG), aortic valve area (AVA), left ventricular ejection fraction (LVEF), left ventricle mass (LVM) and LV mass index (LVMi) were evaluated. Results: A total of 41 patients were included. The age was (75.0±8.6) years, and male patients accounted for 53.7%. There were 19 BAV patients and 22 TAV patients in this cohort. All patients undergoing TAVR using a self-expandable prosthesis Venus-A valve. MPG was (54.16±21.22) mmHg(1 mmHg=0.133 kPa) before TAVR, (21.11±9.04) mmHg at 24 hours after TAVR, (18.84±7.37) mmHg at 1 month after TAVR, (17.68±6.04) mmHg at 6 months after TAVR in BAV group. LVEF was (50.42±13.30)% before TAVR, (53.84±10.59)% at 24 hours after TAVR, (55.68±8.71)% at 1 month after TAVR and (57.42±7.78)% at 6 months after TAVR in BAV group. MPG and LVEF substantially improved at each time point after operation, and the difference was statistically significant (all P<0.05) in BAV group. MPG in TAV group improved at each time point after operation, and the difference was statistically significant (all P<0.05). LVMi was (164.13±49.53), (156.37±39.11), (146.65±38.84) and (134.13±39.83) g/m2 at the 4 time points and the value was significantly reduced at 1 and 6 months post TAVR compared to preoperative level(both P<0.05). LVEF in the TAV group remained unchanged at 24 hours after operation, but it was improved at 1 month and 6 months after operation, and the difference was statistically significant (all P<0.05). LVMi in TAV group substantially improved at each time point after operation, and the difference was statistically significant (all P<0.05). NT-proBNP in both two groups improved after operation, at 1 month and 6 months after operation, and the difference was statistically significant (all P<0.05). MPG in TAV group improved better than in BAV group during the postoperative follow-up (24 hours after TAVR: (11.68±5.09) mmHg vs. (21.11±9.04) mmHg, P<0.001, 1 month after TAVR: (10.82±3.71) mmHg vs. (18.84±7.37) mmHg, P<0.001, 6 months after TAVR: (12.36±4.42) mmHg vs. (17.68±6.04) mmHg, P=0.003). There was no significant difference in NT-proBNP between BAV group and TAV group at each time point after operation (all P>0.05). There was no significant difference in paravalvular regurgitation and second prosthesis implantation between the two groups (all P>0.05). Conclusions: AS patients with BAV or TAV experience hemodynamic improvement and obvious left ventricular reverse remodeling after TAVR, and the therapeutic effects of TAVR are similar between BAV and TAV AS patients in the short-term post TAVR.

RESUMO

Objective:To explore the clinical efficacy of Shugan Lidan decoction(SLD) combined with laparoscopic cholecystectomy on acute calculous cholecystitis(ACC),and explore its mechanism based on network pharmacology. Method:In a retrospective analysis, 121 patients with ACC were divided into laparoscopic cholecystectomy+SLD group (observation group, 68 cases) and laparoscopic cholecystectomy group(control group,53 cases). The postoperative recovery of the patients (time to first exhaust,time to temperature recovery,antibiotic use time and hospitalization time),serum inflammatory factor levels [white blood cell count(WBC),C-reactive protein(CRP),interleukin-6(IL-6)],immune index levels[claster of differentiation(CD)3<sup>+</sup>,CD4<sup>+</sup>/CD8<sup>+</sup>,immunoglobulin M(IgM)] and safety were compared between these two groups. The TCMSP,BATMAN-TCM and TCMIP databases were used to collect all chemical components and targets of SLD. GeneCard and OMIM databases were combined to search ACC-related targets,and then the intersection ones of SLD-related targets and ACC-related targets were extracted to obtain the potential action targets of SLD for treatment of ACC. The STRING database platform was used to establish and analyze the protein-protein interaction (PPI) network,and Bioconductor software package was used for Kyoto encyclopedia of genes and genomes(KEGG) pathway enrichment of the targets. Result:The time to first exhaust,antibiotic use time and hospitalization time of observation group were shorter than those of control group,and the differences were statistically significant(<italic>P</italic><0.05). After treatment,the postoperative WBC,CRP,IL-6,CD4<sup>+</sup>/CD8<sup>+</sup> and IgM in the two groups of patients were lower than those before treatment,and the postoperative CD3<sup>+</sup> was higher than that before treatment,with statistically significant differences(<italic>P</italic><0.05). The postoperative WBC,CRP,IL-6,CD4<sup>+</sup>/CD8<sup>+</sup> and IgM in the observation group were lower than those in control group,and the CD3<sup>+</sup> was higher than that of control group,with statistically significant differences(<italic>P</italic><0.05). There was no statistical difference in adverse reactions between the two groups. Totally 159 components in SLD were screened,which acted synergistically on key targets such as IL-6,vascular endothelial growth factor A(VEGFA),insulin(INS),and epidermal growth factor receptor(EGFR),and participated in the regulation of HIF-1 signaling pathway,EGFR tyrosine kinase inhibitor resistance and PI3K-Akt signaling pathway in the treatment of ACC. Conclusion:SLD may regulate HIF-1 pathway and other signaling pathways by acting on IL-6,VEGFA,INS,EGFR and other targets,thereby reducing postoperative inflammatory factors,improving immune function,and promoting postoperative recovery in patients with ACC.

RESUMO

Ionizing radiation causes the massive apoptosis of human tissue cells,leading to dysfunction of the gastrointestinal tract and hematopoietic system.Thus,high-efficiency,low-toxicity radiation protection drugs are urgently needed.Toll-like receptor agonists have been developed based on the anti-apoptotic mechanism of tumor cells in recent years,which exert their radioprotective effects by activating downstream pathways,mainly nuclear factor-κB.Here we elucidate several agonists of Toll-like receptors involved in radiation protection,with an attempt to inform the research and development of new radiation protection agents.

RESUMO

In order to study the interaction between Pterocephalus hookeri and bitter taste receptors,three-dimensional structural models of bitter taste receptors TAS2 R16,TAS2 R14 and TAS2 R13 were established by homology modeling in this paper. Maestro software was used for docking the chemical constituents of P. hookeri with bitter taste receptors. The results showed that 25 chemical components of P. hookeri can regulate three bitter taste receptors. And these components were mainly iridoid glycosides and phenolic acids.This research focused on the comprehensive application of homology modeling and molecular docking technology to explore the interaction between bitter chemical constituents of P. hookeri and bitter taste receptors. This study provided assistance in revealing pharmacodynamic basis of bitter Tibetan medicine at molecular level. It also provided new ideas and methods for the study of Tibetan medicine.

OBJECTIVE: To investigate the clinical value of pancreaticogastrostomy(PG) in the treatment ofpancreatojejunostomy stricture(PJS) after pancreaticoduodenectomy(PD).METHODS: The clinical data of 3 patients withPJS who failed the endoscopic treatment underwent PG followed by resection of pancreatojejunostomy(PJ) from May2010 to December 2017 in Department of General Surgery,Xinhua Hospital,Shanghai Jiaotong University School ofMedicine were analyzed retrospectively. After the pancreatointestinal anastomosis was explored and resected, thedigestive tract of the remnant pancreas was reconstructed by using the single-layer bundle pancreaticogastric mucosaanastomosis. The intraoperative and postoperative conditions were observed.RESULTS: The median time of presentationwas 72,37 and 21 months. Three cases of operation were completed successfully. The operation time was 137, 210, 120 min,and blood loss was 210, 350, 180 m L. No pancreatic fistula,surgical bleeding and other serve complicationoccurred postoperatively. All the 3 patients experienced resolution of symptoms without recurrent acute pancreatitis afterPG during the follow-up of 23, 58 and 15 months.CONCLUSION: PG especially duct-to-mucosa PG followed byresection of PJ could be used in the PJS patients who failed the endoscopic treatment.

RESUMO

OBJECTIVES@#To explore the injury mechanism of ankle fracture inferred by the Lauge-Hansen classification with the application of medical imageology and its application value in forensic medicine.@*METHODS@#A total of 32 ankle fracture cases with known injury mechanism were collected from January 2013 to May 2018, which were identified in Yongkang Public Security Bureau, Zhejiang Province. The Lauge-Hansen classification of ankle fracture was performed by three forensic experts based on the data of X-ray and CT image. Fisher's exact test and Kappa consistency analysis were performed by SPSS 20.0 statistical software to compare the results of the Lauge-Hansen classification with the injury mechanism of ankle fracture obtained through the criminal evidence.@*RESULTS@#In 32 cases, 84.4% (27/32) ankle fractures were classified according to the Lauge-Hansen classification based on medical imaging. The mechanism of ankle fracture identified by the Lauge-Hansen classification was consistent with that obtained through the criminal evidence.@*CONCLUSIONS@#Based on medical imaging, the Lauge-Hansen classification can be well applied to infer the injury mechanism of ankle fracture in part cases, and provide objective evidence for the crime scene reconstruction of criminal cases.

RESUMO

Objective To provide theoretical basis for the rational use of drugs in clinic, the biochemical characteristics of liver injury induced by Atorvastatin Combined with HRZ (Isoniazid Rifampicin and Pyrazinamide) were analyzed in animal model. Me thods Eighty 8 week old SPF SD rats with half males and females were divided into four groups: control group, atorvastatin group, HRZ group, atorvastatin+HRZ group. According to the human mouse drug dose conversion, mice were given corresponding drugs by gavage.Hepatic function index of rats (the Total bilirubin, Direct bilirubin, Indirect bilirubin, Aspartate aminotransferase, Alanine aminotransferase, Alkaline phosphatase) were detected by blood from the femoral artery and hepatic function index of rats in each group on 10 d, 20 d, 40 d.Re s ults There were significant difference in the anmmistrated group on 10, 20, 40 days with higher TBIL, DBIL, IBIL than that in control group; in the admimistrated group on Day 10, combined treatment group was higher than that in cotrol group and there were significant differences in ALT;in the process of treatmen, there was statistical difference; ALP was administered for 20 days and the 40 day, atorvastatin there was HRZ group was statistically different in groupHRZ, severe injury, combination group compared with HRZ group had statistically significant difference. Conclus ions The liver injury in the three experimental groups is mild and moderate, and the liver damage is mainly cholestasis type. The most severe hepatic injury caused by Atorvastatin Combined with HRZ is aggravated by the prolonged use of drugs.
