Rete middle cerebral artery is an abnormal process of embryonic development, which results in the normal middle cerebral artery trunk being replaced by plexiform vascular network. The main clinical manifestations are intracranial hemorrhage or ischemic cerebrovascular events. Clinicians generally do not know enough about it. This article reviews the generative mechanism, clinical manifestations, differential diagnosis and treatment of the rete middle cerebral artery.

Objective:To investigate clinical features, imaging characteristics, etiology, and potential mechanisms of medullary "comma-shaped" infarctions.Methods:Patients with common-shaped infarction treated at Weihai Central Hospital Affiliated to Qingdao University from January 2020 to September 2023 were retrospectively collected, and their clinical manifestations, imaging findings, treatment, and outcome were analyzed and summarized.Results:A total of 9 patients with medullary common-shaped infarction were enrolled, including 3 males, aged 67.22±14.66 years (ranging from 39 to 83 years). Main clinical symptoms and signs included the decreased pain and temperature sensation on the contralateral limb (66.67%, 6/9), coughing or choking while drinking liquids/dysphagia (66.67%, 6/9), ipsilateral pharyngopalatine muscle paralysis (66.67%, 6/9), and dizziness (66.67%, 6/9). Seven patients (77.78%, 7/9) had severe stenosis or occlusion at the ipsilateral vertebral artery, one (11.11%, 1/9) had occlusion at the left middle cerebral artery, and one (11.11%, 1/9) did not have large vessel stenosis. At 90 days after onset, the follow-up showed that the modified Rankin Scale scores were all <2.Conclusions:Medullary comma-shaped infarctions are rare in clinical practice, its main manifestations include the decreased pain and temperature sensation on the contralateral limb, coughing or choking while drinking liquids/dysphagia, ipsilateral pharyngopalatine muscle paralysis, dizziness, etc. The pathogenesis is mainly hypoperfusion caused by vertebral artery stenosis.

Objective To explore the metabolic markers of social anxiety disorder in schizophrenia patients with social anxiety disorder through metabolomic sequencing analysis.Methods From December 2022 to December 2023,a case-control study was carried out in the Neuropsychiatric Prevention and Control Hospital of Fuzhou Second General Hospital.One hundred sixty patients with schizophrenia were included in the study.The Diagnostic and Statistical Manual of Mental Disorders,fourth edition(DSM-Ⅳ)and Liebowitz social anxiety scale(LSAS)scores were used to classify subjects as patients with social anxiety disorder(n=64)and controls without social anxiety disorder(n=96).Peripheral blood samples were collected for non-targeted metabolomic sequencing,and the metabolites with statistical differences were analyzed by receiver operating characteristic(ROC)curve to find metabolic markers that may affect social anxiety disorder in schizophrenia patients.Results There were significant differences in 12 metabolites between the two groups(P<0.05).In ROC curve analysis,the top 3 metabolites with area under curve(AUC)values were 3-O-trans-coumaryl-alphetolic acid(AUC=0.637),3-mercaptopropionic acid(AUC=0.602)and nona-2-acylcarnitine(AUC=0.600).Conclusion In this study,the potential diagnostic metabolic markers of 3-O-trans-coumaryl-alphitoic acid,3-mercaptopropionic acid,nonyl-2-acylcarnitine as diagnostic metabolic markers can effectively distinguish patients with schizophrenia social anxiety disorder from patients with schizophrenia without social anxiety disorder.

Objective To observe the value of the ratio of cerebral hyperdensities(PCHD)/venous sinus maximum density for predicting hemorrhagic transformation(HT)after endovascular treatment(EVT)in patients with acute ischemic stroke(AIS).Methods Data of 79 AIS patients with PCHD immediately after EVT were retrospectively analyzed.The patients were divided into HT group(n=41)or non-HT group(n=38)based on the presence of HT or not.Clinical data and CT parameters were compared between groups.The value of the ratio of PCHD/venous sinus maximum density for predicting HT was evaluated.Results The maximum density of PCHD and the ratio of PCHD/venous sinus maximum density in HT group were both higher than those in non-HT group(both P＜0.001).Taken 87 HU as the best cut-off value of the maximum density of PCHD,the sensitivity,specificity and area under the curve(AUC)for predicting HT after EVT in AIS patients was 90.24%,71.05%and 0.79,respectively.Taken 0.94 as the best cut-off value of the ratio of PCHD/venous sinus maximum density,the sensitivity,specificity and AUC was 97.56%,71.05%and 0.81,respectively.No significant difference of AUC was found between the former and the latter(P＞0.05).Conclusion The ratio of PCHD/venous sinus maximum density immediately after EVT could be used to predict HT in AIS patients.

ObjectiveTo investigate the therapeutic effect of Dayuanyin on acute lung injury induced by H1N1 infection and decipher the potential mechanism. MethodThe constituents in Dayuanyin were analyzed by ultra-high performance liquid chromatography-quadrupole-exactive orbitrap mass spectrometry （UHPLC-Q-Exactive Orbitrap MS）. Forty-eight female BALB/c mice were randomized into normal， model， oseltamivir （19.5 mg·kg^-1）， and low-， medium-， and high-dose （2.73， 5.46， 10.92 g·kg^-1） Dayuanyin groups. The normal and model groups were administrated with deionized water by gavage， and the other groups were administrated with the corresponding drugs by gavage. On day 3 of drug administration， the normal group received nasal inhalation of normal saline， and the other groups were inoculated intranasally with A/RP/8/34 （H1N1） for the modeling of influenza virus infection. Mice were administrated with drugs continuously for 7 days and weighed daily. Sampling was performed 12 h after the last administration， and the lung tissue was weighed to calculate the lung index. Hematoxylin-eosin staining was performed to observe the pathological and morphological changes of the lung tissue and bronchi. The cytometric bead array （CBA） was used to measure the serum levels of interferon-gamma （IFN-γ）， C-X-C motif ligand 1 （CXCL1）， tumor necrosis factor-alpha （TNF-α）， chemokine ligand 2 （CCL2）， interleukin-12p70 （IL-12p70）， chemokine ligand 5 （CCL5）， interleukin-1β （IL-1β）， chemokine （C-X-C motif） ligand 10 （CXCL10）， granulocyte-macrophage colony-stimulating factor （GM-CSF）， interleukin-10 （IL-10）， interferon-beta （IFN-β）， interferon-alpha （IFN-α）， and interleukin-6 （IL-6）. According to the results of mass spectrometry and network pharmacology， we analyzed the mechanism of Dayuanyin in treating acute lung injury caused by H1N1. The protein levels of extracellular signal-regulated kinase 1/2 （ERK1/2）， p38 mitogen-activated protein kinase （p38 MAPK）， nuclear factor-kappa B （NF-κB）， and their phosphorylated forms were determined by Western blot. The mRNA levels of myeloid differentiation factor 88 （MyD88）， Toll-like receptor 3 （TLR3）， Toll-like receptor 7 （TLR7）， and Toll-like receptor 8 （TLR8） in the lung tissue were measured by Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR）. ResultA total of 57 compounds， including paeoniflorin and baicalein， were detected in Dayuanyin. Compared with the normal group， the model group showed decreased body weight （P<0.01）， lung edema and hemorrhage， increased lung index （P<0.01）， and elevated levels of IFN-γ， IL-12p70， CCL5， IL-1β， CXCL10， GM-CSF， IFN-β， and IL-6 （P<0.01）. Compared with the model group， Dayuanyin attenuated alveolar wall thickening， capillary congestion， and immune cell infiltration， reduced the alterations in body weight and lung index （P<0.01）， and down-regulated the protein levels of IFN-γ， IL-12p70， CCL5， IL-1β， CXCL10， GM-CSF， IFN-β， and IL-6 （P<0.01）. A total of 57 key genes were predicted by network pharmacological analysis， of which the MAPK signaling pathway was the main target signaling pathway. Compared with the normal group， the model group showed up-regulation in the protein levels of phosphorylation （p）-ERK1/2， p-p38 MAPK， and p-NF-κB （P<0.01） and the mRNA levels of TLR7， TLR8， MyD88， and TLR3 （P<0.05， P<0.01）. Compared with the model group， Dayuanyin lowered the phosphorylation levels of ERK1/2， p38 MAPK， and NF-κB p65 in a dose-dependent manner （P<0.01） and down-regulated the mRNA levels of TLR3， TLR7， TLR8， and MyD88 （P<0.01）. ConclusionDayuanyin can prevent and control H1N1 infection-induced acute lung injury by inhibiting the TLR/MAPK/NF-κB signaling pathway.
