Objective To explore the application value of psychophysiological test technique in identification of artificial injury and malingering. Methods CQT test was conducted on 50 students with camouflaged pain and tympanic membrane perforation, respectively, using Tongfang Shenhuo Polygraph Tester (TH 4.0.0.15). T-test and χ2 test were adopted for data analysis. Results The accuracy rate of honest group was higher than that of lying group (P<0.01). There were no significant differences in accuracy rates between automatic scoring and manual scoring,and so were that between mask pain problems' testing and tympanic membrane perforation problems' testing. Conclusion This experiment provides a good research basis for the subsequent real case test.

Objective:To investigate the clinical and gene variant characteristics of benign familial infantile epilepsy in generations of three families.Methods:The clinical data of the three benign familial infantile epilepsy patients with PRRT2 gene variant who were diagnosed and their family members were collected from Children′s Hospital Affiliated to Zhengzhou University between 2018 and 2019. All coding exons from the patients and their parents were screened by targeted next-generation sequencing, and detected variants were verified by Sanger sequencing.Results:In all the patients, a cluster of seizures was observed before one year old,but interictal clinical conditions were normal. The electroencephalograms were all normal in interictal stage. The father of proband 1 presented with convulsion onset at the age of eight months and showed remission before one year old. The grandpa, mother and uncle of proband 2 also presented with convulsion onset in their babyhood of life and showed remission before one year old. The mother of proband 3 presented with convulsion onset in their babyhood of life and showed remission before three years old. Proband 1 carried heterozygous c.937G>C variant in the PRRT2 gene which is inherited from his father. Proband 2 carried c.1075_c.1076insC variant inherited from his mother. A deletion of PRRT2 gene exon 2 was detected in both of proband 3 and her mother. The three variants had not been reported in the Human Gene Mutation Database.Conclusions:Benign familial infantile epilepsy is a kind of inherited epilepsy characterized by early onset of seizure in babyhood with better prognosis, a cluster of focal seizures with or without secondary generalization, and cessation of seizure mostly before two or three years of age. The variants c.937G>C, c.1075_c.1076insC and the deletion of exon 2 in the PRRT2 gene have enriched the gene variant spectrum of benign familial infantile epilepsy.

A rapid and sensitive method for analyzing trace β-blockers in complex biological samples,which involved magnetic solid-phase extraction(MSPE)coupled with Fourier transform ion cyclotron reso-nance mass spectrometry(FTICR-MS),was developed.Novel nanosilver-functionalized magnetic nano-particles with an interlayer of poly(3,4-dihydroxyphenylalanine)(polyDOPA@Ag-MNPs)were synthesized and used as MSPE adsorbents to extract trace β-blockers from biological samples.After extraction,the analytes loaded on the polyDOPA@Ag-MNPs were desorbed using an organic solvent and analyzed by FTICR-MS.The method was rapid and sensitive,with a total detection procedure of less than 10 min as well as limits of detection and quantification in the ranges of 3.5-6.8 pg/mL and 11.7-22.8 pg/mL,respectively.The accuracy of the method was also desirable,with recoveries ranging from 80.9％to 91.0％following the detection of analytes in human blood samples.All the experimental results demonstrated that the developed MSPE-FTICR-MS method was suitable for the rapid and sensitive analysis of trace β-blockers in complex biological samples.

ObjectiveTo study the anti-inflammatory effects of Blumea balsamifera （L.） DC oil （BBO） based on nuclear factor kappa-B （NF-κB） nonclassical and arachidonic acid （AA） pathway. MethodsEffects of BBO on the production of slow reacting substance of anaphylaxis （SRS-A） were detected by the ileal smooth muscle method. The contents of prostaglandin E₂ （PGE₂） and leukotriene B₄ （LTB₄） in lipopolysaccharides （LPS） -induced macrophages were detected by ELISA kit. The expression of COX-2， 5-LOX， FLAP and RelB were detected by qRT-PCR. Western blot was performed to detect the effects of BBO on the level of NF-κB nonclassical pathway proteins TNF receptor associated factor 3 （TRAF3）， TNF receptor associated factor 2 （TRAF2）， NF-κB-inducing kinase （NIK）， p100 and RelB. ResultsThe contractile tension of guinea pig ileum was reduced （P<0.001）， and the SRS-A production inhibition rate reached 65.34% at 1mg·mL^-1 BBO concentration. Compared with LPS group， BBO reduced the concentrations of PGE₂ （P<0.05） and LTB₄ （P<0.05）_， and decreased the expressions of COX-2 （P<0.05）， 5-LOX （P<0.05） and FLAP （P<0.05） in AA pathway at concentrations of 40-80 μg·mL^-1. Moreover， 40-80 μg·mL^-1 BBO decreased the concentrations of TRAF3 （P<0.05）， TRAF2 （P<0.05）， and NIK （P<0.05）， and further inhibited the phosphorylation of p100 （P<0.05）， as well as the level of the transcription factor RelB in genes （P<0.05） and proteins （P<0.05） in nonclassical NF-κB pathway， whereas BBO did not cause such changes. ConclusionBBO may potentially exert its anti-inflammatory effects by suppressing the regulatory proteins TRAF3 and TRAF2 and the transcription factor RelB in NF-κB nonclassical pathway. The inhibitory action extending to the induction kinase function of NIK， further hindering the phosphorylation of p100 and its binding with the transcription factor RelB. Consequently， downstream elements in the AA pathway， including the pivotal rate-limiting enzymes COX-2， 5-LOX and FLAP， were altered. This modulation influences the levels of inflammatory mediators such as PGE₂ and LTB₄.

It can provide reference for standardized data management and application, and also provide a model for establishing and improving of a national rare blood group information network.

Objective:To evaluate the effect of ultrasound-guided internal branch of superior laryngeal nerve(ibSLN) block on the quality of anesthesia recovery in the patients undergoing intracranial tumor surgery.Methods:The data from patients of either gender, aged 18-65 yr, with a body mass index of 18-28 kg/m 2, who underwent intracranial tumor surgery from December 2022 to October 2023, were retrospectively collected. Patients were divided into control group (group C) and ultrasound-guided ibSLN block group (group U). Bilateral ibSLN block was performed with 0.375% ropivacaine hydrochloride 2 ml.The tracheal extubation time, emergence time, development of cardiovascular events within 15 min after extubation, emergence agitation, Ramsay sedation score, Steward recovery score, visual analogue scale scores at 10 min after extubation and development of postoperative sore throat and hoarseness in postanesthesia care unit were recorded. Results:Compared with group C, the incidence of emergence agitation, Ramsay sedation score, visual analogue scale scores and sore throat were significantly decreased, the incidence of hoarseness was increased ( P<0.05), and no significant change was found in the extubation time, emergence time and Steward recovery score in group U( P>0.05). No hypertension, hypotension, tachachycardia and bradycardia were found in two groups. Conclusions:Ultrasound-guided ibSLN block can improve the quality of anesthesia recovery in the patients undergoing intracranial tumor surgery.

Idiopathic pulmonary fibrosis (IPF) is a chronic progressive fibrotic interstitial pneumonia with unknown causes. The incidence rate increases year by year and the prognosis is poor without cure. Recently, phosphatidylinositol 3-kinase (PI3K)/protein kinase B (PKB/AKT) signaling pathway can be considered as a master regulator for IPF. The contribution of the PI3K/AKT in fibrotic processes is increasingly prominent, with PI3K/AKT inhibitors currently under clinical evaluation in IPF. Therefore, PI3K/AKT represents a critical signaling node during fibrogenesis with potential implications for the development of novel anti-fibrotic strategies. This review epitomizes the progress that is being made in understanding the complex interpretation of the cause of IPF, and demonstrates that PI3K/AKT can directly participate to the greatest extent in the formation of IPF or cooperate with other pathways to promote the development of fibrosis. We further summarize promising PI3K/AKT inhibitors with IPF treatment benefits, including inhibitors in clinical trials and pre-clinical studies and natural products, and discuss how these inhibitors mitigate fibrotic progression to explore possible potential agents, which will help to develop effective treatment strategies for IPF in the near future.
