Objective To explore clinical application of coronary artery imaging with 64-slice spiral CT.Methods 46 patients with coronary heart disease were undergone both coronary artery imaging with 64-slice spiral CT and coronary angiography,and the effects on coronary display respectively were compared Results Coronary display in coronary artery imaging with 64-slice spiral CT was better than that of the coronary angiography, which was a inspection pattern of noninvasive coronary display. Conclusion Coronary artery imaging with 64-slice spiral CT can accurately evaluate coronary artery stenosis, which was worth to application.

Nitrogen balance of normal developed, healthy preschool children 4-7 yrs old, lodged in the kindergartens was studied. 105 preschool children were divided into 15 groups at different protein intakes ranged from 6.28g /MJ to 10.35g/MJ. Prominant correlationship was shown between the intake of protein g/MJ (x) and the retained nitrogen g/kg (y), r= 0.6709, n= 15, p

Objective:To analyze the clinical presentations and diagnostic and treatment process of one patient with autoimmune encephalitis(AE)with double positive anti-N-methyl-D-aspartate receptor(NMDAR)and anti-γ-aminobutyric acid B receptor(GABABR)secondary to herpes simplex virus encephalitis(HSVE),and to improve the clinicians'awareness of this disease.Methods:The clinical data of one AE patient with double positive anti-NMDAR and anti-GABABR secondary to HSVE were collected,the diagnostic and therapeutic processes were summarized,and the relevant literatures were reviewed.Results:The patient,a 36-year-old male,developed a headache followed by limb convulsions,and progressed to disturbed consciousness.After admission,the routine biochemistry of the cerebrospinal fluid(CSF)was abnormal,and the herpes simplex virus-1(HSV-1)IgG antibody showed positive in the CSF;both CSF and serum tests for NMDAR antibodies were positive;the head magnetic resonance imaging(MRI)results showed abnormal signals in the right occipital white matter,leading to the diagnosis of HSVE secondary to anti-NMDAR encephalitis.Several months later,the patient experienced psychiatric behavior abnormalities,cognitive dysfunction,and sleep disorders,and both the serum NMDAR and GABABR antibodies showed positive results,prompting the diagnosis of HSVE secondary anti-NMDAR encephalitis and anti-GABABR encephalitis.After treatment with steroid pulse therapy and intravenous immunoglobulin(IVIG),the patient's condition was improved and the patient was discharged.At one-year follow-up,the patient's psychiatric symptoms had completely resolved,leaving mild cognitive impairment.Conclusion:If the clinical symptoms of the patients recovering from antiviral treatment for HSVE is worsened,secondary AE should be highly suspected;it is important to complete autoimmunity antibody testing as soon as possible for the early diagnosis and treatment to improve the prognosis of the patient.

Objective To investigate the effectiveness of Multimodal image fusion and 3D reconstruction techniques in the surgical treatment of posterior cranial fossa tumours surgery.Methods Retrospective analysis of medical records of 19 patients with posterior cranial fossa tumours who underwent surgical treatment between January 2022 and September 2023 in Department of Neurosurgery,the Affiliated People's Hospital of Jiangsu University.All patients underwent preoperative CT and MR imaging of the head,and these image data were input into an image fusion workstation for image fusion and 3D reconstruction.The surgeon then used these fused images for spatial assessment of the tumour and simulation of surgical access.Results The multimodal image fusion techniques could clearly show the anatomical relationship between the tumour of the posterior cranial fossa and the surrounding structures,and there were 15 cases of total resection of the tumour in 19 patients(78.9％),4 cases of subtotal resection,and no perioperative death patients.Postoperative complications included cerebral oedema in 2 cases,intracranial infection in 1 case,facial paralysis in 2 cases,and dysphagia in 1 case.According to the feedback from the surgeons,the multimodal image fusion techniques showed significant value in surgery in 16 cases and ancillary value in 3 cases.Conclusion Multimodal image fusion technology and 3D reconstruction techniques in can accurately and clearly show the spatial relationship between the tumour in the posterior cranial fossa and the surrounding important tissues,which helps the surgeon to more accurately design the surgical incision and choose a more reasonable surgical approach.It has a high auxiliary value for the successful completion of surgery.
