Purpose To analyze the relationship of retinal artery occlusion(RAO) with the white blood cell(WBC) count and inflammatory diseases away from the eyes. Methods Ninety-fours patients with retinal artery occlusion were studied retrospectively.The patients were divided into 2 groups,one of which with inflammatory diseases,the other without.An age and sex matched control group was made. Results Fifty four(58%) cases had inflammatory diseases of various causes at the same time,among which only 14(26%) cases directly involved the eyes.WBC count was significantly higher after the occurrence of RAO(Plt;0.05),comparing with that of the control group. Conclusion Inflammatory diseases away from the eyes may be oneof the factors causing RAO.The increased WBC count may be an inflammatory reaction to RAO. (Chin J Ocul Fundus Dis,1998,14:159-161)
目的 探讨联合检测白细胞计数和C反应蛋白对早期诊断结肠癌术后吻合口漏的意义。方法 回顾性分析山东省菏泽市立医院胃肠外科2009～2012年期间收治的183例结肠癌患者的临床资料，其中术后未发生吻合口漏171例（无吻合口漏组），发生吻合口漏12例（有吻合口漏组），所有患者在术前和术后均无其他感染性并发症。对2组患者术前和术后白细胞计数及C反应蛋白浓度进行了观察与分析。结果 有吻合口漏组患者的平均住院时间为（35±5） d，术后死亡3例（25.0%），长于或高于无吻合口漏组的（12±2） d及5例（2.9%），P＜0.05。术后2组患者白细胞计数在发生漏早期无明显差异，有吻合口漏组患者白细胞计数在漏出现临床症状时显著升高（P＜0.05）。术后2组患者C反应蛋白浓度都较术前增高，无吻合口漏组患者在术后第3天开始逐渐降低；有吻合口漏组患者在术后第4天至第11天与无吻合口漏组患者相比明显增高（P＜0.05）。结论 C反应蛋白相对于白细胞计数在早期诊断吻合口漏方面具有更重要的意义，术后第4天以后出现的C反应蛋白下降后再次上升或持续性升高可能提示有吻合口漏发生。
ObjectiveTo compare the clinical characteristics of inpatients with different influenza subtypes, so as to identify the subtypes at an early stage.MethodsA retrospective case study was conducted, using influenza surveillance data from January 1st, 2016 to December 31st, 2018 at a tertiary surveillance outpost hospital in Chengdu. Patients diagnosed with different subtypes of influenza by nucleic acid testing or virus isolation and culture were investigated, and their clinical characteristics, laboratory test results, and prognosis were analyzed and compared among the four subtypes including H1N1, H3N2, Victoria (BV), and Yamagata (BY).ResultsThere were 127 inpatients with laboratory-confirmed influenza. Among the confirmed influenza patients, 85.8% (109/127) had low or normal white blood cell counts, and 78.8% (89/113) had abnormally high procalcitonin levels. Among the patients with different subtypes, statistical differences existed in age (P<0.001), low or normal white blood cell count (P=0.041), positive bacteria/fungus/mycoplasma/chlamydia culture (P=0.001), kidney damage (P=0.013), outcome at discharge (P<0.001), and hospitalization expenses (P=0.016). However, there was no statistical difference in gender, clinical symptoms, liver damage, cardiac damage, or length of hospital stay (P>0.05).ConclusionThe infection of influenza can lead to severe clinical complications or even death. The outcomes of patients with influenza A may be more severe. An elevated procalcitonin level can be detected in quite a few patients with influenza.
ObjectiveTo study the clinical value of procalcitonin (PCT), WBC count, and C-reactive protein (CRP) in diagnosis of common bile duct stones with acute bile duct infection and systemic inflammatory response syndrome (SIRS).MethodsA total of 80 patients with bile duct stones were retrospectively analyzed, which were divided into two groups, SIRS group (n=40) and non-SIRS group (n=40). The numerical value of PCT, WBC count, and CRP were detected on 1, 4, and 7 day after admission, and calculated the score of acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) on 1 day after admission. Then analyzed the clinical value of PCT, WBC count, and CRP in diagnosis of common bile duct stones with acute bile duct infection and SIRS.ResultsEach area under the ROC curve of PCT, CRP, and WBC count were 0.81, 0.78, and 0.72, respectively, with significant difference (P<0.05). The PCT, CRP, and WBC count had a certain accuracy in diagnosis of common bile duct stones with acute bile duct infection and SIRS. The positive-relationship between PCT, CRP, WBC count and APACHE Ⅱ score was significant (r=0.91, P<0.01; r=0.88, P<0.01; r=0.69, P<0.01).ConclusionTo detect the numerical value of PCT, WBC count, and CRP had significant clinical value in diagnosis of common bile duct stones with acute bile duct infection and SIRS.
Objective To investigate the risk factors for early in-hospital death in patients with acute Stanford type A aortic dissection and emergency surgical treatment. MethodsWe retrospectively analyzed the clinical data of 189 patients with acute Stanford type A aortic dissection who underwent surgery in the First Affiliated Hospital of Xinjiang Medical University between January 2017 and January 2020. There were 160 males and 29 females with an average age of 46.35±9.17 years. All patients underwent surgical treatment within 24 hours. The patients were divided into a survival group (n=160) and a death group (n=29) according to their outcome (survival or death) during hospitalization in our hospital. Perioperative clinical data were analyzed and compared between the two groups. Results The overall in-hospital mortality was 15.34% (29/189). There was a statistical difference between the two groups in white blood cell count, blood glucose, aspartate aminotransferase (AST), bilirubin, creatinine, operative method, operation time, aortic occlusion time, or cardiopulmonary bypass time (P<0.05). Multivariate regression identified white blood cell count [OR=1.142, 95%CI (1.008, 1.293)], bilirubin [OR=0.906, 95%CI (0.833, 0.985)], creatinine [OR=1.009, 95%CI (1.000, 1.017)], cardiopulmonary bypass time [OR=1.013, 95%CI (1.003, 1.024)] as postoperative risk factors for early in-hospital death in the patients undergoing acute Stanford type A aortic dissection surgery (P<0.05). Conclusion Our study demonstrated that white blood cell, bilirubin, creatinine and cardiopulmonary bypass time are independent risk factors for in-hospital death after acute Stanford type A aortic dissection surgery.
Objective To explore the correlation and diagnostic value of neutrophil-to-lymphocyte ratio (NLR) and red blood cell distribution width (RDW) in peripheral blood of patients with exacerbation of chronic obstructive pulmonary disease (COPD). Methods One hundred patients with acute exacerbation of COPD who were hospitalized in the hospital between January 2019 and October 2020 were selected as exacerbation group, and another 100 patients with stable COPD who received treatment during the same time period were enrolled as stable group. The general data of patients were collected, and blood samples were collected to detect hemoglobin (Hb), platelet count (PLT), white blood cell count (WBC), neutrophil count, lymphocyte count and RDW, and the NLR was calculated. The correlation between the detection indicators was analyzed and receiver operating characteristic (ROC) curve was drawn to analyze the detection significance of related indicators. Results There were no statistical differences in the levels of Hb and PLT between the exacerbation group and the stable group (P>0.05). The levels of WBC, NLR, RDW and high-sensitivity C-reactive protein (hs-CRP) in the exacerbation group were significantly higher than those in the stable group (all P<0.05). NLR in the patients with acute exacerbation of COPD was positively correlated with serological indicators of WBC and hs-CRP (all P<0.05). ROC curve showed that the sensitivity and specificity of NLR in the diagnosis of acute exacerbation of COPD were 92.0% and 68.0% respectively, those of RDW were 91.0% and 58.0% respectively, those of hs-CRP were 77.0% and 71.0% respectively, and those of NLR+RDW were 90.0% and 73.0% respectively. NLR had the highest diagnostic specificity, RDW had the highest diagnostic sensitivity, and NLR+RDW had the best diagnostic efficiency. Conclusions Serological indicators of WBC, hs-CRP, NLR and RDW in patients with acute exacerbation of COPD will be abnormally increased, and NLR has a positive correlation with WBC and hs-CRP. NLR and RDW have high specificity and high sensitivity respectively in the diagnosis of patients with exacerbation of COPD, and their detection can strengthen the diagnosis and mastery of disease in patients.
