Between PFO and ischemic stroke has been confirmed， and the concept of PFO-AS was officially established in 2020. Contradictory embolism is considered the main pathogenesis of PFO-AS. Fibrinogen， a coagulation factor mainly synthesized by the liver， is closely related to thrombosis and is also an important risk factor for occurrence and recurrence of ischemic stroke， Its level is closely related to polymorphism of fibrinogen promoter. Currently analyzed fibrinogen β（FGβ） there more than 10，which HindⅢ（β-148C/T） gene polymorphism in the FGβ gene promoter region is closely related to plasma fibrinogen level and ischemic stroke. Therefore， a better understanding of genetic variation and susceptibility gene may be one of the best methods to help us prevent，diagnose，treat and improve the prognosis of stroke in the early stages.

Objective This study investigated the regulatory effect of high mobility group protein B1 (HMGB1) in the peripheral blood of patients with primary immune thrombocytopenia (ITP) on myeloid dendritic cells (mDC) and Th17/regulatory T cells (Treg) balance. Methods The study enrolled 30 newly diagnosed ITP patients and 30 healthy controls.Flow cytometry was used to measure the proportion of mDC, Th17, and Treg cells in the peripheral blood of ITP patients and healthy controls. ELISA was conducted to quantify the serum levels of HMGB1, interleukin 6 (IL-6), IL-23, IL-17, and transforming growth factor β(TGF-β). The mRNA levels of retinoic acid-related orphan receptor γt(RORγt) and forehead box P3(FOXP3) were detected by real-time PCR. The correlation between the abovementioned cells, cytokines, and platelet count was assessed using Pearson linear correlation analysis. Results The proportion of Th17 cells and the expression levels of HMGB1, IL-6, IL-23, IL-17 and the level of RORγt mRNA in the peripheral blood of ITP patients were higher than those in healthy controls. However, the Treg cell proportion and TGF-β level were lower in ITP patients than those in healthy controls. In patients with ITP, the proportion of mDC and the level of FOXP3 mRNA did not show significant changes. The proportion of mDC cells was significantly correlated with the expression of IL-6 and IL-23. Moreover, the expression of HMGB1 showed a significant correlation with the expression of mDC, IL-6, IL-23, RORγt mRNA, and IL-17. Notably, both the proportion of mDC cells and the expression of HMGB1 were negatively correlated with platelet count. Conclusion The high expression of HMGB1 in peripheral blood of ITP patients may induce Th17/Treg imbalance by promoting the maturation of mDC and affecting the secretion of cytokines, thereby potentially playing a role in the immunological mechanism of ITP.

Objective:To investigate the association between single nucleotide polymorphism (SNP) of the protein phosphatase 1 regulatory subunit 1B( PPP1R1B) gene and schizophrenia in the Han population of northern Henan province. Methods:Utilizing Psychiatric Genomics Consortium 3 (PGC3) data, the SNPs of PPP1R1B gene which were significantly associated with schizophrenia were screened.Subsequently, totally 1 721 schizophrenia patients and 6 726 healthy controls from the Han population in northern Henan province were recruited for further analysis. The SNP rs907094, located within the PPP1R1B gene was validated, and the clinical symptoms of 386 schizophrenia patients were evaluated using the positive and negative syndrome scale (PANSS). Additionally, expression quantitative trait loci (eQTL) association analysis was conducted to explore the relationship between the rs907094 polymorphism and PPP1R1B gene expression.The PLINK v1.9, Genetic Power Calculater, SPSS 20.0 softwares were used for data analysis. Results:Significant differences in genotype AA, AG, GG(schizophrenia group: AA, 489(28.4%); AG, 848(49.3%); GG, 384(22.3%); control group: AA, 1 450(21.6%); AG, 3 386(50.3%); GG, 1 890(28.1%), χ2=45.418, P<0.05) and allele frequency(schizophrenia group: A, 1 826(53.1%); G, 1 616(46.9%); control group: A, 6 286(46.7%); G, 7 166(53.3%), χ2=43.877, P<0.05) were observed for SNP rs907094 between the schizophrenia group and control group. Individuals carrying allele A were identified to have a higher risk of developing schizophrenia compared to those carrying allele G ( OR=1.288, 95% CI=1.195-1.388). Furthermore, the genotype PPP1R1B gene was found to be associated with the clinical features of schizophrenia. A statistically significant difference was observed in the excitement/hostility factor between AA and GG patients with rs907094 (13.62±5.65, 15.54±4.66)( P<0.05). Additionally, significant differences were noted in the cognitive factor scores between AA and GA genotypes (17.76±5.58, 19.43±5.73)( P<0.05). Conclusions:In the Han population from northern Henan province, the rs907094 polymorphism of the PPP1R1B gene is associated with schizophrenia.And the specific locus may be implicated in arousal/hostility symptoms and cognitive dysfunction.

Uveitis-glaucoma-hyphema syndrome is a rare complication after intraocular lens (IOL) implantation.The cause of the disease is the mechanical friction of the intraocular lens on the anterior segment structures.There is no unified consensus on the pathogenesis of UGH syndrome, and it is generally accepted that disruption of the blood-aqueous humor barrier and reverse pupillary block are the two common mechanisms.The typical clinical manifestations of UGH syndrome include anterior chamber inflammation, increased intraocular pressure and hyphema, with or without vitreous hemorrhage.It is easily misdiagnosed as uveitis.If untreated, it can lead to serious consequences such as loss of vision.The diagnosis of UGH syndrome is based on IOL implantation history, slit-lamp microscopy examination (especially after pupil dilation) that observes an IOL deviation or absence of the capsule, and an ultrasound biomicroscopy that observes contact between IOL and the iris or ciliary body.Treatment for UGH syndrome includes drugs, lasers, and surgery.At present, surgery is the primary method, mainly including IOL alignment, IOL removal or replacement, capsular tension ring implantation, etc.Laser treatments include laser iridoplasty, laser iridotomy and ciliary body laser photocoagulation.UGH syndrome has been reported more frequently abroad and is only reported as case reports in China.The purpose of this review is to discuss the etiology, pathogenesis and diagnosis of UGH syndrome.In addition, we discuss the treatment and caveats of UGH syndrome.The aim of review is to provide a more comprehensive basis for clinicians to understand, diagnose and treat UGH syndrome.

Objective To analyze the causes of acute intestinal obstruction after intracerebral hemorrhage,and the therapeutic effect of rectal dripping with Dachengqi decoction and Fusu agent on acute intestinal obstruction complicated with septic shock.Methods The clinical data of a patient with acute intestinal obstruction complicated with septic shock after intracerebral hemorrhage,who was admitted to the Hospital of Chengdu University of Traditional Chinese Medicine(TCM)on March 5,2022,were retrospectively analyzed.The study aimed to observe the effects of rectal dripping with TCM on the recovery of intestinal function and improvement of shock.Results The patient was a 52-year-old male who underwent"left temporal craniotomy intracranial decompression,craniocerebral hematoma removal,cerebrospinal fluid leak repair"on February 19,2022 due to cerebral hemorrhage.On the 7th day after operation,the patient had hiccups and abdominal distension,and after treatment,the patient developed fever,consciousness disorders,hypotension and other symptoms.Abdominal CT showed extensive intestinal fluid,gas and expansion.Hemodynamic monitoring indicated high discharge and low resistance,intra-abdominal pressure was 21 cmH2O(1 cmH2O≈0.098 kPa),and laboratory examination showed increased inflammatory indexes and abnormal biochemical indexes.The western medicine diagnosis was acute intestinal obstruction complicated with septic shock,and the symptomatic treatments such as organ support(lung,circulation,kidney),anti-infection,fluid resuscitation,analgesia and sedation were given.The TCM diagnosis was intestinal knot(yangming visceral substantive,sudden collapse of yang-qi),with treatment principles focusing on tongfu heat relief,wenshen qianyang,Dachengqi decoction and Fusu agent was added and reduced according to the syndrome differentiation,with medications administered rectally.After the use of TCM decoction,the patient's defecation volume increased significantly,the intra-abdominal pressure decreased to the normal range,abdominal distension was significantly reduced,and the shock was relieved.On the 17th day after the operation,the patient's symptoms improved,the respiratory cycle was stable,and the patient was successfully transferred out of intensive care unit(ICU).Conclusion The treatment of acute intestinal obstruction complicated with septic shock by rectal dripping with Dachengqi decoction and Fusu agent can quickly relieve the condition and promote the recovery of intestinal function.

Objective To investigate the expression of disulfidptosis-related genes in hepatocellular carcinoma(HCC)and the prognostic value of disulfidptosis in HCC,to construct a prognostic model,and to analyze its impact on the biological processes of HCC and sorafenib resistance.Methods The TCGA-LIHC database was used to collect the mRNA expression profiles and corresponding clinical data of HCC patients,and the LASSO-Cox regression algorithm was used to construct a four-gene predictive model for prognosis in the TCGA cohort.The external datasets ICGC and GSE14520 were used to validate the prognostic efficacy of the model,and the Cancer Drug Sensitivity Genomics(GDSC)data were used to investigate the value of the disulfidptosis model in predicting sorafenib treatment response,and gene ontology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG)analyses were used to investigate the biological functions of disulfidptosis-related genes.The independent-samples t test was used for comparison of continuous data between two groups,and the chi-square test was used for comparison of categorical data between two groups.The Kaplan-Meier curve and the log-rank test were used to evaluate the difference in prognosis,and univariate and multivariate Cox regression analyses were used to investigate whether risk score was an independent influencing factor for patient prognosis.Results The univariate Cox regression analysis in the TCGA cohort showed that seven known disulfidptosis-related genes were significantly associated with overall survival(OS)in HCC(all P<0.05).The LASSO-Cox regression analysis was used to construct a prognostic model based on disulfidptosis-related genes(DRG),and the risk score RS-DRG was calculated as RS-DRG=(0.061 6)×GYS1 expression level+(0.152 8)×LRPPRC expression level+(0.268 3)×RPN1 expression level+(0.183 5)×SLC7A11 expression level.The log-rank test showed that the patients with a high risk score based on the disulfidptosis model had a significantly lower OS than those with a low risk score(P<0.001).Based on the results of the multivariate Cox regression analysis,risk score was an independent predictive factor for OS in both TCGA and ICGC cohorts(TCGA:hazard ratio[HR]=1.869,P=0.002;ICGC:HR=3.469,P=0.004).The Spearman correlation analysis showed that RS-DRG was significantly positively correlated with the infiltration level of various immune cells(including B lymphocytes,CD4+T lymphocytes,neutrophils,macrophages,and dendritic cells)in tumor microenvironment(all P<0.05).The patients in the high-risk score group had a significantly lower IC50 value of sorafenib and were more sensitive to sorafenib(P<0.001).The KEGG/GO enrichment analysis showed that the differentially expressed disulfidptosis-related genes were significantly enriched in various mitosis-related molecular functions.Conclusion This study constructed a novel prognostic model based on disulfidptosis-related genes,which has a potential clinical value in predicting the prognosis of HCC,and targeting disulfidptosis-related genes may provide a promising approach for HCC treatment.

Embolic stroke of undetermined source （ESUS） is currently considered to be a subtype of cryptogenic stroke featuring embolic stroke on imaging but with no specific or recognized cause of stroke identified after careful diagnostic evaluation. It was speculated that anticoagulant therapy was more effective than antiplatelet therapy for secondary prevention of stroke in patients with ESUS. However， in fact， several ESUS trials showed that anticoagulant therapy was neither safer nor more effective compared with aspirin. Therefore， a more accurate understanding and determination of the etiology of ESUS is the key to treatment. In this paper， we discuss the background， definition， and diagnosis of ESUS， and analyze its etiology and the relationship between emboli and ESUS from the perspective of embolus source， with the aim to improve clinicians'understanding of ESUS.
