ABSTRACT

Objective:To investigate the distribution features of anti-neutrophil cytoplasmic antibody (ANCA) in patients with cardiovascular and cerebrovascular diseases and the clinical characteristics of the patients.Methods:Clinical data of 6 759 patients who were treated in Baoding No.1 Central Hospital for cardiovascular and cerebrovascular diseases during January 2015 to July 2019 were collected and analyzed. ANCA was detected by indirect immunofluorescence (IIF). Antibodies against myeloperoxidase (MPO) and protease 3 (PR3) were detected by enzyme-linked immunosorbent assay (ELISA).Results:IIF showed that 558 out of the 6 759 cases tested positive for ANCA with a positive rate of 8.26%. Among them, 382 (68.46%) were positive for perinuclear ANCA (p-ANCA) and 176 (31.54%) were positive for cytoplasmic ANCA (c-ANCA). Anti-MPO and anti-PR3 antibodies were detected in 69 ANCA-positive cases, while the antibodies against other target antigens were detected in 489 cases. The ratio between the two groups was 1∶7.09. The incidence of recurrent respiratory tract infection and pulmonary interstitial lesions in ANCA-positive cases was 69.35% (387/558) and 64.52% (360/558), respectively, which was significantly higher than that in ANCA-negative patients [40.51% (2 512/6 201) and 33.17% (2 057/6 201)].Conclusions:Anti-MPO and anti-PR3 antibody detection could not replace IIF to detect total ANCA for a high rate of missed diagnosis would be caused. Early detection of ANCA would be of great significance to patients with chronic cardiovascular and cerebrovascular diseases.

ABSTRACT

Objective To investigate the expression of Nek8 in esophageal squamous cell carcinoma(ESCC) tissues and cell line , and to evaluate its correlation with the clinicopathological features of ESCC and the survival rate of ESCC patients after operation . Methods The expression of Nek8 mRNA in human ESCC Eca109 cell line and two pairs of ESCC tissues and adjacent normal e‐sophageal mucosal epithelium were detected by semi‐quantitative reverse transcription polymerase chain reaction (RT‐PCR) .Immu‐nohistochemistry and tissue microarray technique were used to examine the expression of Nek 8 protein in ESCC tissues and tumor‐adjacent tissues .The correlation between Nek8 expression and clinicopathological features of ESCC and survival rate of ESCC pa‐tients was then analyzed .Results The expression of Nek8 mRNA was positive in Eca109 cells and two cases of ESCC tissue ,and it was negative in paired normal esophageal mucosal epithelium specimens .In tissue microarray ,the expression of Nek8 protein in ES‐CC tissues ,which was mainly in the cytoplasm ,was significantly higher than that in tumor‐adjacent tissues(P= 2 .16E‐13) .The high expression of Nek8 was associated with tumor size (P=0 .008) ,but not with sex ,age ,histological grade ,infiltration degree , lymph node metastasis ,and the survival rate(P>0 .05) .Conclusion The expression of Nek8 is up‐regulated in ESCC tissues and cell line ,and may be involved in tumorigenesis and development of ESCC .Nek8 could act as a potential biomarker for ESCC diag‐nose and target for therapy .

ABSTRACT

<p><b>OBJECTIVE</b>To explore the distribution of the main clinical symptoms and signs of primary biliary cirrhosis (PBC) in a population of individuals with positivity for anti-mitochondrial antibody-M2 (AMA-M2).</p><p><b>METHODS</b>A total of 20 970 persons who participated in routine health examinations at our hospital were tested for presence and level of antinuclear antibodies (ANAs) using an indirect immunofluorescence (IIF) assay and of AMA-M2 by western blotting. The chi-square test was used for statistical analysis.</p><p><b>RESULTS</b>Titers of ANAs more than 1:320 were detected in 1 243 of all the study participants, with 156 of those individuals having detectable AMA-M2.The overall rate ofAMA-M2 positivity was 0.74%, with a significantly higher rate among female subjects (males:0.3% (32/10 550) vs.females:1.2% (124/10 420); x2=55.85, P less than 0.05). Among the AMA-M2-positive population there were 66 cases of abnormal liver function, 58 cases of increased alkaline phosphatase, 72 cases of abnormal findings for routine blood testing, 47 cases of gallbladder disease history, 49 cases of diabetes history, 22 cases of allergy, 75 cases of abdominal discomfort, 38 cases of weakness, 3 cases of jaundice, and 11 cases of pruritus. There were significant differences between the AMA-M2-negative individuals and the AMA-M2-positive individuals.</p><p><b>CONCLUSION</b>Among the general population, individuals with substandard states of health, such as those with abnormal findings in routine blood tests and abnormal liver function, should be screened for AMA-M2. This screening will facilitate early diagnosis of PBC and timely initiation of disease management, improving the patient's life quality of life and prolonging their life.</p>

ABSTRACT

Objective To study the distribution of antinuclear antibodies ( ANAs) in a healthy population and the significance of using ANAs screening test in medical examination .Methods The ANAs were measured by indirect immunofluorescence assay ( IIF) .The Western blot assay was used to detect fif-teen specific antibodies against auto-antigens .Results 3519 out of all 25 110 subjects showed ANAs titers>1∶100 , and among them male and female subjects were respectively accounted for 1143 and 2376 .1489 out of all subjects had ANAs titers >1∶320 , and among them male and female subjects were respectively accounted for 406 and 1083 .The positive rates of ANAs at different titers showed significant differences be -tween male and female subjects .Among subjects with ANAs titers >1∶320 , the number of male subjects showed a steady increase with the age , while the percentage of female subjects reached to two peaks during the periods of puberty and menopause .The fifteen specific antibodies were detected in 659 out of 1489 sub-jects with ANAs titers>1∶320 and anti-Ro-52 (14.2%) accounted for the majority , followed by anti-M2 (12.7%) and anti-SSA (9.6%).Conclusion ANAs can be detected among healthy population of all ages, but their distribution varied with gender and age .ANAs screening test is necessary for medical exami-nation of healthy population , especially for female during period of puberty or menopause .The population with positive ANAs should be followed-up closely and educated for the prevention of autoimmune diseases .
