ABSTRACT
Objective:To assess the relationship between serum total bilirubin and fundus arteriosclerosis in different genders.Methods:The physical examination data of Huadong Sanatorium in 2018 were analyzed, and a total of 26 275 people were included in this retrospective cross-sectional study. The age of this study was 18-86 (47.7±11.1) years old. Among them, there were 15 244 males (58.02%) and 11 031 females (41.98%). Participants were divided into 4 groups according to total bilirubin quartile values: Q1<11.50 μmol/L, Q2∶11.50-13.93 μmol/L, Q3∶13.94-17.14 μmol/L and Q4>17.14 μmol/L. The relationship between total serum bilirubin and fundus arteriosclerosis is determined using univariate and multivariate logistic regression analysis methods. The restricted cubic spline method was used to detect the dose-response relationship between total bilirubin and fundus arteriosclerosis. Results:In males, univariate analysis showed that high level of total bilirubin was a protective factor for fundus arteriosclerosis ( OR=0.87, 95% CI 0.78-0.97, P=0.012). After adjusting for other confounding factors, multivariate analysis showed that high level of total bilirubin remained as an independent protective factor for fundus arteriosclerosis ( OR=0.86, 95% CI 0.74-0.99, P=0.047). There was a linear dose-response relationship between total bilirubin level and fundus arteriosclerosis ( P=0.012). In females, univariate analysis showed that there were no statistically significant association between high level of total bilirubin and fundus arteriosclerosis ( OR=0.96, 95% CI 0.80-1.17, P=0.709). After adjusting for other confounding factors, multivariate analysis showed no statistically significant association between high level of total bilirubin and fundus arteriosclerosis ( OR=0.98, 95% CI 0.76-1.27, P=0.888). No linear dose-response relationship between total bilirubin level and fundus arteriosclerosis was found in females ( P=0.253). Conclusion:There are gender differences in the relationship between total bilirubin and fundus arteriosclerosis in this cohort. Elevated levels of total bilirubin are associated with fundus arteriosclerosis in males but not in females.
ABSTRACT
Objective To establish serum pepsinogen (PG)reference range healthy crowd with latex-enhanced immunoturbi-dimetry of and explore its clinical application in stomach disease in Shanghai area.Methods Selected randomly 8 763 healthy adults who livied in Shanghai for more than 10 years and 269 patients with different stomach trouble confirmed by gastro-scope and pathology.By latex-enhanced immunoturbidimetry to detect the serum pepsinogen Ⅰ (PGⅠ)and pepsinogen Ⅱ(PGⅡ).Results The serum PGⅠ,PGⅡand PGⅠ/PGⅡlevel showed a skew distribution.The normal reference range was 24.6~98.97 ng/ml,≤21.7 ng/ml and ≥3.43.PGⅠand PGR values decreased significantly in both atrophic gastritis (PGⅠ=36.6 ng/ml,P=0.007,PGR=3.63,P<0.001)and gastric cancer groups(PGⅠ=20.6 ng/ml,PGR=3.2,P<0.001).PGⅠand PGⅡvalues increased significantly in digestive ulcer group(PGⅠ=83.6 ng/ml,PGⅡ=17.5 ng/ml,P<0.001),but PGR values decreased significantly (PGR=4.37,P=0.006).Conclusion Establishing serum pepsinogen refer-ence range of healthy crowd with latex-enhanced immunoturbidimetry in the Shanghai area can help to diagnose better the stomach trouble.
ABSTRACT
Objective:To analyze data of 5604 cases who received health examination in our hospital ,and understand morbidities of overweight and obesity in these people and their relationship with blood glucose level . Methods :Morning venous blood was taken from the 5604 subjects undergoing health examination to measure blood glucose lev‐el ,and their body weight and height were measured at the same time ,then body mass index (BMI) was calculated and analyzed .Results:Among the 5604 subjects , prevalence rates of overweight and obesity were 42.1% and 13. 3% respectively ,and they were 50% and 16. 4% in men ,and 25. 4% and 6. 8% in women respectively .Among different age groups (except ≥71 years group) , prevalence rate of overweight in men was significantly higher than that of women , P<0.01 all;except ≥61 years subjects , prevalence rate of obesity in men was significantly higher than that of women ,P<0.01 .In overweight group ,risk relative (RR) of impaired fasting blood glucose and dia‐betes mellitus to those of subjects with normal body weight was 2.32 (95% CI 1.91~2.82) and 2.92 (95% CI 2.31~3.70) respectively ;in obesity group , RR of impaired fasting blood glucose and diabetes mellitus to those of subjects with normal body weight was 3.2 (95% CI 2.57~3.99) and 5.17 (95% CI 4.53~5.90) respectively , P=0.001 all . Conclusion:Overweight and obesity have become a common problem among our customer groups .Compared with those with normal body weight ,overweight and obesity greatly increase risk ratio of impaired fasting blood glucose .
ABSTRACT
Objective To investigate the clinical significance of combined detection of serum pepsinogen (PG) and anti-Hp IgG antibody in early screening for gastric ulcer .Methods 65 patients confirmed as gastric ulcer for the first time were selected as ulcer group ,while 65 healthy people in the same period as the control group .Transmission detection using latex enhanced immune nephe-lometry was adopted to detect their serum PG Ⅰ ,PG Ⅱ and the PG Ⅰ /PG Ⅱ ratio (PGR) was calculated .Enzyme-linked immu-nosorbent assay(ELISA) was used to detect serum anti-Hp IgG antibody .Results The average concentration of serum PG Ⅰand PG Ⅱof patients in the ulcer group were (167 .14 ± 22 .43) ,(26 .68 ± 11 .24) ng/mL ,respectively ,and PGR was 8 .07 ± 1 .19 .The average concentration of serum PG Ⅰand PG Ⅱof subjects in the control group were (52 .15 ± 20 .17) ,(11 .26 ± 7 .68) ng/mL ,re-spectively ,and PGR was 3 .48 ± 1 .92 .The differences of PGⅠ ,PGⅡand PGR between the two group showed statistical significance (P<0 .05) .The positive rate of serum anti-Hp IgG antibody of patients in the ulcer group was 80 .5% ,which was obviously higher than that in the control group(26 .3% )(P<0 .05) .The serum PGⅠ ,PGⅡand PGR of subjects in Hp infection positive group were markedly higher than those in the negative group(P<0 .05) .Conclusion Combined detection of serum PG and anti-Hp IgG anti-body may be used as an screening indicators for early gastric ulcer .
