Objective To evaluate the detection of membrane neutrophil alkaline phosphatase (NAP)in diagnosis of infection in patients with acute cerebral hemorrhage.Methods A total of 208 patients with acute cerebral hemorrhage,including 1 52 cases without infection (uninfected group)and 56 cases with infection (infected group),admitted in the Second Affiliated Hospital of Nantong University during January 201 0 to July 201 6 were enrolled,30 healthy subjects were also enrolled in the study as control group.The peripheral blood from all subjects were collected,and the counts of white blood cell (WBC), percentage of neutrophil,serum procalcitonin (PCT)and NAP were measured.The value of above 4 indicators in diagnosing infection was determined by receiver operating characteristic (ROC ) curves. ANOVA and t test were used to analyze the data,Pearson correlation was performed to analyze the correlation between NAP and PCT in infected group.Results The levels of WBC,percentage of neutrophil and NAP in both infected and uninfected group were higher than those in healthy control group at admission(F =1 1 7.64, 1 00.69 and 425.09,all P <0.01 ),and the levels of WBC,PCT and NAP were also higher when infection occurred compared with those at admission in infected group (t =3.1 4,34.30 and 36.39,all P <0.01 ). The expression of NAP was positively correlated with PCT in infected group (r =0.762,P <0.05).ROC curve analysis showed that the areas under the curves of NAP and PCT in diagnosis of infection were 0.875 and 0.884,respectively.When 1 0655.28 AB/c and 5.01 mg/L were taken as cut-off values,the sensitivities of NAP and PCT in diagnosis of infection were 85.50% and 87.66%;the specificities were 90.50%和 90.31 %,respectively.The level of NAP in infected patients with gram-positive bacterial infections was higher than that in patients with gram-negative bacterial infections (t =6.29,P <0.01 ). Conclusion The expression of NAP in patients with acute cerebral hemorrhage increases when infection occurs,which may be helpful to the clinical diagnosis of bacterial infection.

Objective:To study the clinical phenotype and molecular genetic characteristics of a Chinese Han family with X-linked retinoschisis (XLRS), and to determine the associated gene variations.Methods:A pedigree investigation was performed.The clinical characteristics and pedigree analysis of a Han Chinese family line with XLRS was conducted in August 2021 at the Xiamen Eye Center Affiliated to Xiamen University.All patients and the carriers underwent comprehensive medical history collection and routine ophthalmological examinations, including visual acuity, non-contact tonometer, slit lamp microscope, direct ophthalmoscope, and optical coherence tomography.The proband and some patients underwent medical optometry, fundus photography or wide-angle fundus photography, and electroretinogram examination.Peripheral venous blood samples were collected from the family members, and whole exome sequencing (WES) analysis was performed on the proband samples.For variants screened by WES, the expanded verification in other patients and normal persons in the family was carried out by Sanger sequencing.Multiple bioinformatic tools were used to analyze the pathogenicity of variants.This study protocol was approved by the Ethics Committee of Xiamen Eye Center of Xiamen University (No.XMYKZX-KY-2021-012). Written informed consent forms were obtained from each subject or guardian of minors.CADD, FATHMM and other bioinformatics tools were used to analyze the pathogenicity of the variation sites.Results:The Han XLRS pedigree consisted of 8 individuals in 3 generations.Out of the 3 cases diagnosed with XLRS based on clinical evaluation, all were male.The mother of the proband was a carrier of related genes.There were 5 persons with normal phenotypes.There was no history of consanguineous marriages within the family, and the disease was shown to be intergenerational, which is consistent with the recessive inheritance of the X chromosome.None of the patients had a history of systemic disease or any other abnormal manifestations.The prevailing feature of ophthalmopathy was poor binocular vision since childhood.The proband and his younger brother had spoke split in the macula, and their grandfather showed atrophy of retinal nerve fibers.Genetic analysis revealed a hemizygous variation c. 214G>C: p.Glu72Gln in the RS1 gene in all the patients in this family.The proband's mother was heterozygous at this site, and all other phenotypically normal family members exhibited wild type at this site.This variant was predicted to be a deleterious variation and likely to cause disease based on bioinformatics analysis. Conclusions:The proband and patients in this Han Chinese family have the known c. 214G>C: p.Glu72Gln hemizygous variation of the RS1 gene and exhibit mild XLRS, which was consistent with the recessive inheritance of X chromosome.
