Objective:To investigate the clinical manifestations, serological and cerebrospinal fluid test results for syphilis, imaging features, and prognoses of cerebral syphilitic gumma.Methods:The clinical data of 1 patient with cerebral syphilitic gumma admitted to Department of Neurology, Second Affiliated Hospital of Soochow University in March 2023 were retrospectively analyzed. Papers about cerebral syphilitic gumma were searched from journals in Journal Citation Reports Q1 from 2000 to 2019, journals from 2020 to 2024 in PubMed, WOS, Embase, and Scopus databases, and journals from 2000 to 2024 in Wanfang Database, CNKI, and VIP database; the clinical data of 54 patients with cerebral syphilitic gumma reported in above databases and 1 patient in our hospital were collected for pooled analysis.Results:The main clinical manifestations of 55 cerebral syphilitic gumma patients included headache (32, 58.2%), lateral limb/facial weakness (25, 45.5%), nausea and vomiting (14, 25.5%), dizziness (11, 20.0%), sensory disturbances (10, 18.2%), blurred vision (7, 12.7%), seizure (5, 9.1%)), hearing loss (5, 9.1%), tinnitus (5, 9.1%), memory loss (3, 5.5%), aphasia (3, 5.5%), dysarthria (2, 3.6%), drop attack (2, 3.6%), weakness in opening eyes (2, 3.6%), unresponsiveness (1, 1.8%), Argyll-Robertson pupil (1, 1.8%), tabes dorsalis gait (1, 1.8%), and fever (1, 1.8%). In 51 patients who reported complete serologic test results, 45 patients (88.2%) were positive for non-specific antibodies to syphilis, and all patients were positive for specific antibodies to syphilis. In 34 patients underwent cerebrospinal fluid examination, 25 (73.5%) were positive for non-specific antibodies to syphilis, and 32 (94.1%) were positive for specific antibodies to syphilis. Isolated intracranial lesion (43, 78.2%) was mostly common in imaging test, and the frequently involved cranial sites were, orderly, the frontal lobe (14, 25.5%), parietal lobe (14, 25.5%), temporal lobe (5, 9.1%), frontotemporal lobe (3, 5.5%), frontoparietal lobe (2, 3.6%), parieto-occipital lobe (2, 3.6%), nucleus pulposus (1, 1.8%), clivus (1/55, 1.8%), and cerebral peduncle of the midbrain (1, 1.8%). Thirty patients (54.5%) were misdiagnosed as having other intracranial space-occupied diseases, orderly, glioma (11, 36.7%), metastatic tumors (5, 16.7%), meningiomas (4, 13.3%), other unexplained intracranial space-occupying (4, 13.3%), brain abscess (3, 10.0%), cavernous hemangioma (1, 3.3%), intracranial lymphoma (1, 3.3%), auditory nerve and pituitary tumors (1, 3.3%). Of the 42 patients who reported prognosis after anti-syphilitic treatments, 41 had varying degrees of improvement, and one died of brain herniation.Conclusion:Because of atypical clinical manifestations and lack of clear diagnostic criteria, cerebral syphilitic gumma is often misdiagnosed as intracranial tumors; cerebral syphilitic gumma should be considered in patients with positive non-specific antibodies to syphilis/specific antibodies to syphilis in serum and cerebrospinal fluid having neurological symptoms and intracranial space-occupied foci; timely diagnosed and treated patients can prognosed well.

Objective To understand the prevalence characteristics of influenza and changes of influenza virus strains,and provide reference for the prevention and control of influenza in the province.Methods Surveillance da-ta about influenza in Hunan Province from 2014 to 2023 were exported from China Influenza Surveillance Informa-tion System.Differences in the percentage of influenza-like illness(ILI)cases(percentage of influenza-like cases[ILI％]in outpatient and emergency department visits)among different years and different populations,as well as the positive rate of influenza virus in ILI specimens were compared.Results From 2014 to 2023,over 2.65 million cases of ILI were reported,with an ILI％of 4.70％.ILI％among different years presented statistically significant differences(P＜0.001).People aged 0-14 years old were the main population with ILI,accounting for 82.90％.The positive rate of influenza virus in ILI specimens was 14.14％,the positive rate of influenza virus among diffe-rent years and age groups were both significantly different(both P＜0.001).The main prevalent influenza strains from 2014 to 2023 included types A(H1N1),A(H3N2),B(Victoria),and B(Yamagata),alternating among di-fferent years.However,type B(Yamagata)strains were not detected from 2020 to 2023.There were basically two influenza prevalence seasons every year,namely winter-spring and summer.Conclusion People＜15 years old are the main population of influenza,and the prevalence peaks are in winter-spring and summer.From 2021 to 2023,the prevalence alternates mainly among 3 types:A(H1N1),A(H3N2),and B(Victoria).

Objective To elucidate the molecular genetic etiology of patients with disorders of sex development(DSD)using whole exome sequencing(WES),thereby enhancing our understanding of the underlying mechanisms of sexual development abnormalities.Methods Retrospective analysis was conducted on clinical data of 60 DSD patients diagnosed in the First People's Hospital of Yunnan Province between March 2008 and August 2021,with an additional family study for one proband.Genomic DNA was extracted from patients for WES analysis.Single nucleotide polymorphism(SNP)and insertions/deletion(InDel)tests were identified using SAMtools software in conjunction with established SNP and InDel databases.Copy number variations(CNVs)at the exon level were detected using ExomeDepth,while the potential pathogenicity of mutations was predicted with PolyPhen-2,Mutation taster and PyMol software,with Sanger sequencing employed for confirmation.Results The study included 22 patients with 46,XX DSD and 38 with 46,XY DSD.Among the 46,XX DSD patients,the SRY gene was detected in 14 patients.In the remaining 8 patients and a proband's families,single nucleotide site variations(SNVs)of NR5A1,PROKR2 and ANOS1 genes were identified in 2 patients,and CNVs in CYP21A2 gene were found in 4 patients.The pathogenicity of CYP21A2 EX1 Dup has been previously reported,while the remaining 3 CNVs were of uncertain significance,and no DSD-related mutations were detected in 2 patients.In the WES analysis of 46,XY DSD patients,10 pathogenic or likely pathogenic SNVs across 5 genes(SRY,AR,SRD5A2,CYP17A1,and NR5A1)were identified in 14 patients.Additionally,5 likely pathogenic CNVs involving the CYP21A2,AKR1C2,CBX2,and NR5A1 genes were detected in 5 patients,comprising 3 deletions and 2 duplications.Novel SNVs in NR5A1(c.722G>T,c.48C>G)and ANOS1 c.564A>T were identified,with no prior reports in relevant databases.The pathogenicity of CYP21A2 EX1 Dup is documented in related databases,while the remaining CNVs have not been previously reported.Conclusion The utilization of WES technology has enhanced the diagnostic potential for DSD,broadened the spectrum of known DSD-related gene mutations,and deepened our comprehension of DSD pathogenesis,offering valuable support for genetic counseling.

Aneurysmal subarachnoid hemorrhage(aSAH),primarily caused by the rupture of intracranial aneurysms with bleeding into the subarachnoid space,is an acute neurological disease associated with high disability and mortality.Brain injury after aSAH results from a combination of injury mechanisms,with early brain injury(EBI)occurring within 72 hours post-onset,laying the foundation for subsequent pathophysiological changes in the brain and poor prognosis of patients.Among them,the brain immunoinflammatory response,involving the interaction of various immune cells and active substances,plays a significant role in post-aSAH EBI,and is related to delayed brain injury and long-term prognosis.Systemic inflammatory response following aSAH can also affect the prognosis and outcome of patients.This review summarizes the role of local and systemic immune inflammatory responses in the occurrence and progression of aSAH,as well as the research progress on related inflammatory biomarkers and therapeutic prospects,aiming to provide a theoretical reference for new treatment for aSAH.

Objective To explore artificial reconstruction vs artificial intelligence reconstruction in coronary artery volume rendering(VR).Methods A total of 110 coronary heart disease(CHD)patients were enrolled in the study,and underwent computed tomography arteriography.Artificial reconstruction(artificial group)and artificial intelligence reconstruction(intelligent group)were conducted in coronary artery VR.The image quality of VR and curved planar reconstruction(CPR),the diagnosis coincidence rate of arterial stenosis,and vascular reconstruction score were compared between two groups.Results The VR image quality of intelligent group was significantly higher than that of artificial group,with excellence rate of 90.91%vs 80.00%;and intelligent group scored higher than artificial group in CPR image quality(P<0.05).The differences in the diagnostic coincidence rates of arterial vessels(RCA,LAD,LCX)with no stenosis,slight stenosis,moderate stenosis,and vascular occlusion between two groups were trivial(P>0.05),while the two groups differed significantly in the diagnosis coincidence rates of mild stenosis and severe stenosis(P<0.05).The mean total score,the median value of the 3 main branches+posterior descending branch+intermediate branch+diagonal branch+blunt margin branch,and the median value of the other vascular branches were all significantly increased in intelligent group as compared with artificial group(P<0.05).Conclusion Artificial intelligence reconstruction has higher application value than artificial reconstruction in coronary artery VR.

Objective To measure and compare the lateral posterior tibial slope (LPTS) , medial posterior tibial slope ( MPTS) and tibial torsion angle ( TTA) between the patients of recuiTent patellar dislocation and the heathy people, and to analyze the correlation between LPTS, MPTS and TTA and the risk factors of recuiTent patellar dislocation. Methods A total of 33 patients (44 knees) with recuiTent patellar dislocation in our hospital from July 2019 to June 2021 were selected and listed as the stud)' group. Twenty-three subjects (46 knees) who were suspected iliac vascular and lower limb vascular diseases during the same period were selected and listed as the control group. All the enrolled researchers had fulllength CT scans date of the lower limbs. Three-dimensional models were reconstructed using Mimics 21. 0 software and then imported into 3-matic software. The LPTS, MPTS and TTA were measured and compared between the two groups. Results In the study group, the LPTS, MPTS and TTA were (7. 69} 1. 42) ° , ( 10. 06} 1. 71) ° , ( 36. 42}8. 13 ) ° , respectively while the control group, the LPTS, MPTS and TTA were ( 8. 42 } 1. 65 ) ° , ( 10. 44 } 0. 86 ) ° , ( 25. 77} 3. 90 ) ° , respectively. There were no signiiicant differences in the LPTS, MPTS and TTA between different genders and sides both in the stud)' group and the control group ( P > 0. 0 5 ) . Compared with the control group, the LPTS in the stud)' group was smaller, and the difference was statistically significant (P<0. 0 5 ) . There was no statistically significant difference between the stud)' group and the control group in the MPTS (P>0. 05). Compared with the control group, the TTA in the stud)' group was higher, and the difference was statistically significant (P< 0. 0 5 ) . Compared with the control group, the LPTS and MPTS in the study group were significant asymmetry, and the difference was statistically significant ( P < 0 . 0 5 ). Conclusion The lateral posterior tibial slope of patients with recurrent patellar dislocation is significantly smaller than that in the healthy people, while there is no significant difference in the medial posterior tibial slope; The tibial torsion angle of patients with recurrent patellar dislocation is significantly larger than in the healthy people; The lateral posterior tibial slope and tibial torsion angle have certain correlation with recurrent patellar dislocation, which can conduct the diagnosis of recurrent patellar dislocation.

ObjectiveTo investigate the effect and mechanism of Mori Folium extract on the glucose and lipid metabolism disorders in the liver of rats with type 2 diabetes mellitus （T2DM） through the phosphatidylinositol 3-kinase/protein kinase B/peroxisome proliferation-activated receptor α/carnitine palmitoyl transferase-1 （PI3K/Akt/PPARα/CPT-1） signaling pathway. MethodThe T2DM model was induced by the high-fat diet combined with the intraperitoneal injection of streptozotocin （STZ）. The model rats were randomly divided into a model group， a metformin （0.2 g·kg^-1） group， and a Mori Folium water extract （4.0 g·kg^-1） group according to blood glucose and body weight. In the 8-week administration， fasting blood glucose was measured at the same time every week. The histomorphological and fat changes in the rat liver were observed by hematoxylin-eosin （HE） staining and oil red O staining. The levels of total cholesterol （TC）， triglyceride （TG）， low-density lipoprotein cholesterol （LDL-C）， high-density lipoprotein cholesterol （HDL-C）， alanine aminotransferase （ALT）， and aspartate aminotransferase （AST） in the serum were measured by biochemical methods. Western blot （WB） was used to quantitatively detect the protein expression of p-PI3K，PI3K，p-Akt，Akt，PPARα，and CPT-1 in the rat liver. ResultAfter 8-week administration， the blood glucose of rats was higher in the model group than that in the control group （P<0.01）， and lower in the Mori Folium water extract group than that in the model group （P<0.01）. The results of HE staining showed that the liver tissue structure of the control group was complete， and the hepatocytes were arranged radially around the central vein， while the hepatocyte injury in the model group was obvious. Compared with the model group， the Mori Folium water extract group showed improved vacuolar degeneration and no lesions such as small bile duct hyperplasia. Oil red O staining showed that there was no obvious steatosis and necrosis in the hepatocytes of rats in the control group， and no lipid droplets in the hepatocytes were observed， while the model group showed increased lipid droplets. Mori Folium significantly reduced the lipid droplets in the liver. Biochemical analysis showed that the levels of TC， TG， LDL-C， AST， and ALT in the model group were significantly higher than those in control group （P<0.01）. The levels of TC， TG， LDL-C， AST， and ALT in the Mori Folium water extract group were significantly lower than those in the model group （P<0.05，P<0.01）. WB showed that the protein expression of p-PI3K/PI3K， p-Akt/Akt， PPARα， and CPT-1 in the model group were lower than those in the control group （P<0.01）. Mori Folium water extract could increase the protein expression of p-PI3K/PI3K， p-Akt/Akt， PPARα， and CPT-1 （P<0.05 or P<0.01）. ConclusionThe hypoglycemic mechanism of Mori Folium water extract may be related to the regulation of the PI3K/Akt/PPARα/CPT-1 signaling pathway.
