ABSTRACT
Objective@#To assess the application of quantitative immunochemical fecal occult blood test (qFIT) in screening of gastrointestinal diseases for health check-up population.@*Methods@#Total 19 633 health check-up subjects, who received qFIT in AiKang Guobin Physical Examination Center from January 2018 to June 2019 qFIT, were enroll in the study. The positive rate of subjects who received qFIT were analyzed. Gastrointestinal endoscopy were used to diagnose gastrointestinal lesions. The application of qFIT in screening gastrointestinal diseases, especially colorectal cancer and precancerous lesions was evaluated.@*Results@#Total 718 (3.66%) subjects were positive for qFIT, among whom 103 (42.3%) underwent gastrointestinal endoscopic examinations. Finally, 33 (42.3%) cases of colon adenoma, 9 (11.5%) cases of peptic ulcer, and 4 (3.1%) cases of colorectal cancer were detected; and other conditions including gastroenteritis and hemorrhoids were were also diagnosed. There were 87 cases whose qFIT were negative performed colon endoscopy, 5 (5.7%) cases of colon adenoma, no colorectal cancer were detected. The mean value of qFIT for colon cancer was higher than that for polyps (3 569±1 085)μg/L vs. (823±106) μg/L, P=0.01]. The detection rate of colon polyps in qFIT positive subjects was higher than that in qFIT negative subjects [32%(33/103) vs.5.7% (5/87)], and the detective rate of colon cancer in qFIT positive subjects was higher than that in qFIT negative subjects [3.9%(4/103) vs.0(0/87)].@*Conclusion@#Quantitative immunochemical fecal occult blood test can improve the detection rate of colorectal cancer and precancerous lesions in screening of gastrointestinal diseases.
ABSTRACT
Objective To understand the situation of eosinophils absolute value and percentage in the population of occupational health examination in Changsha City ,and to analyze the distribution situation of physical examination abnormal results of eosino‐phils absolute value(EOS) and percentage(EOS% ) .Methods The blood cell analysis results and physical examination abnormal manifestations in 22 135 cases of occupational health examination were statistically analyzed .Results Among cases of EOS absolute value and EOS% increase ,the majority had the changes of EKG abnormality ,fatty liver ,etc .the minority were reactive and clonal increase ,meanwhile the cases of unknown cause eosinophils increase also accounted for a large proportion .Conclusion It is sugges‐ted that a large number of experiments and clinical studies should be carried out for further investigate the significance of eosino‐phils increase in the occupational health examination .
ABSTRACT
Objective To analyze the relationship of the serum concentration of TSH in pregestational women with pregnancy and pregnant outcome,and to investigate the high risk value of TSH in eugenic and healthy examination before pregnancy.Methods The distribution of TSH in fertile woman and the relationship of serum TSH level with sex hormone levels,rate of pregnancy,and adverse pregnant outcomes (no healthy infants were born,abortion,premature delivery,and malformation) were investigated in national-free pregestational eugenic and healthy examination during 2013.The high risk level of TSH in pregestational women was determined.Results The average level of TSH in 5 798 prepregnant women was 2.36 mIU/L with the median of 2.01 mIU/L,and the serum level of TSH showed abnormal distribution with long tail.The pregnant rate of fertile women within one year was 76.1％.The beneficial range of TSH levels for pregnancy was 0.35-3.5 mIU/L,while the pregnant rate in other ranges of TSH level was decreased with statistically significant difference (P＜0.01).When the concentration of TSH was below 0.35 mIU/L or above 5.5 mIU/L,abnormal pregnant outcomes were significantly increased (P＜0.01).Logistic regression analysis indicated that the relative risks of infertility and abnormal pregnant outcomes were significantly increased.Compared with TSH 0.35-2.5 mIU/L group,there were significantly differences in FSH,LH,and estradiol (E2) in TSH＞4.5 mIU/L or＜0.35 mIU/L group (P＜0.01).TSH was related with LH,E2,progesterone,and prolactin (r=0.29,-0.28,-0.37,0.36).Conclusion The high risk value of serum TSH in prepregnant women should be below 0.35 mIU/L or above 5.5 mIU/L.
