Objective:Explore the predictive value of the C-reactive protein to albumin ratio (CAR) and combined indicators for the prognosis of cardiac arrest (CA) patients.Methods:Retrospective analysis was conducted on patients who recovered spontaneous circulation after cardiopulmonary resuscitation (CPR) admitted to the First Affiliated Hospital of Zhengzhou University from January 2021 to May 2023. Patients were divided into survival and non-survival groups based on their status at discharge. Baseline characteristics, CPR data, and laboratory indicators were compared between the two groups. Statistically significant indicators were further analyzed using multivariate logistic regression to identify independent risk factors affecting the prognosis of CA patients. Receiver operating characteristic (ROC) curves were constructed to assess the predictive value of each independent factor and combined indicators for the prognosis of CA patients.Results:A total of 145 patients were included in the study, including 33 patients in the survival group and 112 patients in the non-survival group. There were statistically significant differences between the survival group and the non-survival group in terms of CPR duration, the dosage of vasopressor drugs used, ICU length of stay, Acute Physiology and Chronic Health EvaluationⅡ (APACHEⅡ) score at ICU admission, lactate, fibrinogen, aspartate aminotransferase, albumin, procalcitonin, C-reactive protein, CAR, myoglobin, and creatine kinase isoenzyme (all P < 0.05). Multivariate logistic regression analysis revealed that CAR and CPR duration were independent risk factors affecting the prognosis of CA patients (CAR: OR=2.372, 95% CI: 1.094~5.146, P=0.029; CPR duration: OR=1.170, 95% CI: 1.020~1.342, P=0.025). ROC curve analysis showed that the areas under the curve for CAR, CPR duration, and their combination in predicting patient prognosis were 0.792, 0.731, and 0.859, respectively. The cut-off values for CAR and CPR duration were 1.455 and 11.5 minutes, respectively. Conclusions:The CAR and CPR duration are independent risk factors affecting the prognosis of CA patients, and the predictive value is higher when both CAR and CPR duration are combined. A CAR greater than 1.455 and a CPR duration longer than 11.5 minutes suggest a poorer prognosis for the patients.

In recent years, with the rapid development of organ donation after citizen’s death and transplantation, central and local governments in China have successively released incentive policies. To protect the legitimate rights and interests of organ donors after citizen’s death and their families, current status of incentive policies for organ donation after citizen’s death was illustrated and analyzed from the perspective of ethics. Combining with the principles of justice, respect for autonomy, nonmaleficence and beneficence, the problems existing in the implementation of incentive policies for organ donation after citizen’s death were identified in China, such as lack of continuous psychological intervention in spiritual incentives, the misinterpretation of humanitarian assistance in practice and the impact of indirect economic incentives on individual donation autonomy, etc. Relevant countermeasures and suggestions were proposed at the government, society and individual levels, aiming to provide reference for improving the incentive policies for organ donation after citizen’s death and accelerate the development of organ donation in China.

Dementia is a neurodegenerative disease closely related to brain network dysfunction. In this study, we assessed the interdependence between brain regions in patients with early-stage dementia based on phase-lock values, and constructed a functional brain network, selecting network feature parameters for metrics based on complex network analysis methods. At the same time, the entropy information characterizing the EEG signals in time domain, frequency domain and time-frequency domain, as well as the nonlinear dynamics features such as Hjorth and Hurst indexes were extracted, respectively. Based on the statistical analysis, the feature parameters with significant differences between different conditions were screened to construct feature vectors, and finally multiple machine learning algorithms were used to realize the recognition of early categories of dementia patients. The results showed that the fusion of multiple features performed well in the categorization of Alzheimer's disease, frontotemporal lobe dementia and healthy controls, especially in the identification of Alzheimer's disease and healthy controls, the accuracy of β-band reached 98%, which showed its effectiveness. This study provides new ideas for the early diagnosis of dementia and computer-assisted diagnostic methods.

Medicine is essentially an anthropology, and the patient role is characterized by integrity and subjectivity. With the progress of science and technology and social development, the contemporary patient role has become alienated. The specific manifestations of patient role alienation were analyzed from four aspects, including the objectification of the patient role and the blurring of the patient boundaries in sociology, the objectification of the patient role and the indexing of patients’ pain in technology, the challenge of patient life and health rights and the alienation of informed consent rights in law, and the instrumentalization of patient role and the fragility of patient subjectivity in economics. This paper proposed that the coordination of technology and humanities, the return to the nature of patients, and the concern for the needs of patients are essential in the development of modern medicine.

Objective To compare the curative effect of anti-relfux plastic stent and common plastic stent in treatment of malignant biliary obstruction.Method 22 cases of anti-reflux biliary plastic stent implantation and 30 cases of common bile duct stent implantation from March 2013 to April 2016 were selected as study subject, then compare the operation time, one-time success rate, postoperative pancreatitis, cholangitis, patency, differences in survival situation.Result There was no significant difference between the two groups in the aspects of the operation time, one-time success rate of recent cholangitis after surgery, postoperative pancreatitis (P > 0.05), but there was significant difference between the three aspects of long term patency, cholangitis, survival period (P < 0.05).Conclusion The anti-relfux biliary stent has good long-term curative effect in treatment of malignant biliary obstruction, which worth of further exploration and research.
