Objective:To explore the clinical value of mean platelet volume/platelet count ratio(MPV/PLT)in predicting short-term prognosis of elderly patients with acute exacerbation of chronic obstructive pulmonary disease(AECOPD).Methods:A total of 226 elderly patients with AECOPD admitted to our hospital from January 2017 to January 2019 were retrospectively enrolled as research subjects.All cases were divided into the survival group(n=175)and the death group(n=51), based on prognosis 28-day after admission.General data and laboratory test results were compared between the two groups.The relevant factors for death were analyzed by the Logistic regression equation.The receiver operating characteristic(ROC)curve was used to evaluate the prognostic value of MPV/PLT, and the Kaplan-Meier survival curve was drawn according to the cut-off.Methods:Compared with the survival group, Acute Physiology and Chronic Health Status Evaluation(APACHEⅡ)score, levels of procalcitonin(PCT), high-sensitivity C-reactive protein(hs-CRP), creatinine, neutrophil count(NEU), lymphocyte count(LYM)and MPV were elevated, and levels of albumin and PLT decreased in the death group( P<0.05). Hospital stay lengths and costs were higher in the death group than in the survival group( P<0.05). The level of MPV/PLT was higher in the death group than in the survival group(0.065±0.016 vs.0.054±0.013, t=5.036, P<0.01). Multivariate Logistic regression showed that MPV/PLT was an independent risk factor for recent death( OR=2.331, 95% CI: 1.772-8.224, P<0.01). ROC curve analysis showed that the area under the curve(AUC)of MPV/PLT was 0.829, the sensitivity was 83.41%, the specificity was 82.80%, and the cut-off was 0.061.Optimal cut-off value analysis showed that APACHEⅡ score, PCT and hs-CRP levels and mortality were higher in patients with MPV/PLT≥0.061 than in patients with MPV/PLT<0.061( P<0.05). The Kaplan Meier survival curve showed that the cumulative survival rate was lower in those with MPV/PLT≥0.061 than in those with MPV/PLT<0.061( Log- rank=6.323, P<0.05). Conclusions:The increase of MPV/PLT may be an independent risk factor for recent death in elderly patients with AECOPD and has good clinical value in predicting poor prognosis.

Traumatic rib fractures are the most common injury in thoracic trauma. Previously,the patients with traumatic rib fractures were mostly treated non-surgically,of which 50%,especially those combined with flail chest presented chronic pain or chest wall deformities and over 30% had long-term disabilities,being unable to retain a full-time job. In the past two decades,thanks to the development of internal fixation material technology,the surgical treatment of rib fractures has achieved good outcomes. However,there are still some problems in clinical treatment,including inconsistency in surgical treatment and quality control in medical services. The current consensuses on the management of regional traumatic rib fractures published at home and abroad mainly focus on the guidance of the overall treatment decisions and plans,and relevant clinical guidelines abroad lacks progress in surgical treatment of rib fractures in recent years. Therefore,the Chinese Society of Traumatology affiliated to Chinese Medical Association and Chinese College of Trauma Surgeons affiliated to Chinese Medical Doctor Association,in conjunction with national multidisciplinary experts,formulate the Chinese Consensus for Surgical Treatment of Traumatic Rib Fractures(2021)following the principle of evidence-based medicine,scientific nature and practicality. This expert consensus puts forward some clear,applicable,and graded recommendations from aspects of preoperative imaging evaluation,surgical indications,timing of surgery,surgical methods,rib fracture sites for surgical fixation,internal fixation methods and material selections,treatment of combined injuries in rib fractures,in order to provide references for surgical treatment of traumatic rib fractures.
