Serum myocardial markers troponin I (cTnI), creatine kinase isoenzyme (CK-MB), myoglobin (MYO), WBC count, and PDW levels were measured at admission, and analyzed for individual indicators. And individual and combined detections of these indicators in early diagnosis of acute myocardial infarction (AMI) were analysed.Results: Serum cTnI, CK-MB, MYO, WBC count and PDW level were higher in the observation group than those in the control group, and the difference between the groups was statistically significant. Of the 100 patients with positive myocardial injury markers, 48 (48.00%) were diagnosed with AMI by final clinical diagnosis. Compared with the control group, the positive rate of serum index and the combined detection of five indicators in the observation group were significantly increased. The sensitivity and specificity of the five indicators combined detection and diagnosis of AMI were 95.83% and 94.23%, respectively, which were higher than the individual detection of each index, and the difference was statistically significant.Conclusions: The combined detection of serum cTnI, CK-MB, MYO, WBC count and PDW is helpful for early diagnosis of AMI and can improve the sensitivity and specificity of diagnosis.展开更多

Methods: This retrospective case-controlled study was performed among 200 healthy people and 200 patients with a primary diagnosis of acute appendicitis between October 2017 and June 2018. The patients were classified into three groups: the acute complicated appendicitis (suppurative and gangrenous) group, acute non-complicated appendicitis group and the control group. Red blood cell, white blood cell, lymphocyte, monocyte and platelets count, red blood cell distribution width, hemoglobin, hematocrit, mean platelet volume, platelet distribution width, and C-reactive protein were compared between the groups. Results: Thirty-nine (19.5%) patients with acute appendicitis had no complication and 161 (80.5%) developed a complication. The white blood cell count, neutrophil count and C-reactive protein serum levels were significantly higher, whereas the mean age, lymphocyte count, monocyte count, red blood cell distribution width and platelet count were significantly lower in acute appendicitis patients with and without complications compared with the control group. Moreover, combined analysis of best diagnostic parameters (white blood cell, neutrophil and lymphocyte counts) showed that combined parallel sensitivity and specificity were 98.7% and 42.7%, respectively. Conclusions: White blood cell, lymphocyte counts and neutrophil count could be used for diagnosis of acute appendicitis. More over the utility of mean platelet volume for differential diagnosis might be overestimated.展开更多

Methods: A total of 2813 pregnant women who received regular antenatal care until delivery were included. Participants were divided into 3 groups: normotensive pregnant women (n = 2621), women with PE without severe features (n = 169), and women with PE with severe features (n = 23). Blood samples were collected during antenatal visits and/or during the period of in-patient hospital stay, and changes in platelet indices were compared among the three groups. Results: Platelet count (PC) was decreasing while mean platelet volume (MPV) and platelet distribution width (PDW) were increasing as PE progressed. Receiver operating characteristics (ROC) curve analysis showed that PDW had the largest area under curve (AUC) [0.980 (95% CI: 0.964 - 1.000)], making it the best marker for predicting development of PE. Also, PDW showed the most statistically significant correlation with mean arterial pressure (MAP) (r = 0.902, p = 0.000), making it the best marker for predicting severity of hypertension. Conclusion: This study provides evidence that PC decreases while MPV and PDW increase as pregnancy advances, and these changes are more pronounced in PE than normotensive pregnancy. These changes predate development of PE by 2 - 8 weeks and are proportional to the progress of this disorder. The selected platelet indices, especially PDW, have the potential to be utilized as markers for not only prediction of PE development but also severity of hypertension.展开更多
