To explore the role of kidney yang in the "transformation of inflammation and cancer" of chronic obstructive pulmonary disease based on "Qi controlling Xu" / 国际中医中药杂志

Chronic obstructive pneumonia cancer transformation refers to the malignant transformation of long-term repeated chronic inflammation of the lung. Traditional Chinese Medicine believes that the etiology and pathogenesis of chronic obstructive pneumonia cancer transformation always belong to the deficiency of origin and excess of signs. Chronic obstructive pulmonary disease causes damage to the qi of the lung, spleen and kidney. Qi is yang, and qi deficiency leads to yang deficiency. Yang deficiency and abnormal warm would result in qi stagnation, phlegm coagulation and blood stasis. It is the key to the transformation of chronic obstructive pneumonia cancer. Kidney yang is the root of yang qi. Deficiency of kidney yang is the initiating factor for the transformation of chronic obstructive pneumonia cancer. Deficiency of lung yang is the fundamental factor for the transformation of chronic obstructive pneumonia cancer. Deficiency of kidney yang and deficiency of spleen yang are the driving factors for the transformation of chronic obstructive pneumonia cancer. Therefore, this article discussed the role of kidney yang in the transformation of chronic obstructive pneumonia cancer from the theory of "Qi Zhu Xu Zhi", in order to broaden the thinking of clinical diagnosis and treatment of the disease.

Establishment and verification of risk prediction model of acute exacerbation of chronic obstructive pulmonary disease based on regression analysis / 中华危重病急救医学

Objective:To establish a risk prediction model for acute exacerbation of chronic obstructive pulmonary disease (AECOPD) using regression analysis and verify the model.Methods:The risk factors and acute exacerbation of 1 326 patients with chronic obstructive pulmonary disease (COPD) who entered the stable phase and followed up for 6 months in the four completed multi-center large-sample randomized controlled trials were retrospectively analyzed. Using the conversion-random number generator, about 80% of the 1 326 cases were randomly selected as the model group ( n = 1 074), and about 20% were the verification group ( n = 252). The data from the model group were selected, and Logistic regression analysis was used to screen independent risk factors for AECOPD, and an AECOPD risk prediction model was established; the model group and validation group data were substituted into the model, respectively, and the receiver operating characteristic (ROC) curve was drawn to verify the effectiveness of the risk prediction model in predicting AECOPD. Results:There were no statistically significant differences in general information (gender, smoking status, comorbidities, education level, etc.), body mass index (BMI) classification, lung function [forced expiratory volume in 1 second (FEV1), forced vital capacity (FVC), etc.], disease status (the number and duration of acute exacerbation in the past year, duration of disease, etc.), quality of life scale [COPD assessment test (CAT), etc.] and clinical symptoms (cough, chest tightness, etc.) between the model group and the validation group. It showed that the two sets of data had good homogeneity, and the cases in the validation group could be used to verify the effectiveness of the risk prediction model established through the model group data to predict AECOPD. Logistic regression analysis showed that gender [odds ratio ( OR) = 1.679, 95% confidence interval (95% CI) was 1.221-2.308, P = 0.001], BMI classification ( OR = 0.576, 95% CI was 0.331-1.000, P = 0.050), FEV1 ( OR = 0.551, 95% CI was 0.352-0.863, P = 0.009), number of acute exacerbation ( OR = 1.344, 95% CI was 1.245-1.451, P = 0.000) and duration of acute exacerbation ( OR = 1.018, 95% CI was 1.002-1.034, P = 0.024) were independent risk factors for AECOPD. A risk prediction model for AECOPD was constructed based on the results of regression analysis: probability of acute exacerbation ( P) = 1/(1+ e- x), x = -3.274 + 0.518×gender-0.552×BMI classification + 0.296×number of acute exacerbation + 0.018×duration of acute exacerbation-0.596×FEV1. The ROC curve analysis verified that the area under ROC curve (AUC) of the model group was 0.740, the AUC of the verification group was 0.688; the maximum Youden index of the model was 0.371, the corresponding best cut-off value of prediction probability was 0.197, the sensitivity was 80.1%, and the specificity was 57.0%. Conclusion:The AECOPD risk prediction model based on the regression analysis method had a moderate predictive power for the acute exacerbation risk of COPD patients, and could assist clinical diagnosis and treatment decision in a certain degree.
