Chronic heart failure （CHF） represents the terminal stage of numerous cardiovascular diseases. According to traditional Chinese medicine theory， the pathogenesis of CHF is characterized by deficiency of the root and excess of the branch. The deficiency of the root mainly stems from insufficiency of heart Qi， while the excess of the branch arises from pathological accumulation of phlegm， blood stasis， and fluid retention. During the occurrence and development of CHF， the disobedience of heart Qi consistently serves as the key to the onset of the disease. As elucidated in Da Lun Chapter of WU Yun Xing in The Yellow Emperor's Inner Classic： Plain Questions， "harmony when conforming to qi and illness when going against Qi". This principle describes the relationship between human physiology and nature Qi dynamics. Harmony leads to health， while disobedience leads to illness. The same principle can be applied within the human body， that is， harmony between the zang-fu organs and their Qi leads to health， while disobedience leads to illness. The occurrence of CHF and the relationship between the heart and heart Qi also follow this principle. This study started from this theory， analyzed the relationship between "following or going against Qi" and the occurrence of diseases in the human body， further analyzing the "following" and "going against" between the heart and heart Qi， the pathogenesis of CHF， the corresponding relationship between the heart Qi and modern physiology in the state of "following Qi"， the corresponding situation between the heart Qi and modern pathology in the state of "going against Qi"， and the relationship between "going against Qi" and different stages of CHF. Moreover， it proposed to treat CHF from the perspective of "illness when going against Qi". One is to replenish the insufficiency of heart Qi （tonifying heart Qi and also invigorating the spleen）， and the other is to unblock the channels of heart Qi （resolving phlegm and removing turbidity to unblock the channels， removing blood stasis and dredging collaterals to promote blood circulation， and transforming fluid retention and expelling water to facilitate blood flow）. Meanwhile， the effects of single-herb Chinese medicines and Chinese-medicine compound prescriptions on the myocardium and micro-indexes of the human body under the "tonifying" and "unblocking" methods were analyzed. Through the above-mentioned treatment methods， the nature of heart Qi can finally be restored to "abundant" and "unobstructed"， so that the heart Qi can be harmonized and CHF can be improved. These findings may provide a new way of thinking for the future treatment of CHF.

Objective:To investigate the risk factors for futile recanalization in patients with acute anterior circulation large vessel occlusion after endovascular mechanical thrombectomy (EMT), and establish a nomogram model predicting futile recanalization in these patients.Methods:One hundred and eighty-eight patients with acute anterior circulation large vessel occlusion after EMT were enrolled from Department of Neurology, Zhongshan Hospital of Chinese Medicine, Guangzhou University of Chinese Medicine from January 2018 to December 2021. Patients were divided into futile recanalization group and effective recanalization group according to whether futile recanalization occurred; futile recanalization was defined as successful recanalization showed by immediate postoperative DSA (modified thrombolysis in cerebral infarction [mTICI] ≥2b), but poor functional outcome (modified Rankin Scale [mRS] scores>2 90 d after surgery). The clinical data were compared between futile recanalization group and effective recanalization group. Multivariate Logistic regression analysis was used to screen the risk factors for futile recanalization. R software was used to establish a nomogram model for futile recanalization. C-index was used to evaluate the differentiation of the model, and correction curve was used to evaluate the accuracy of the line graph model prediction. Receiver operating characteristic (ROC) curve was used to evaluate the predictive efficiency of the nomogram model.Results:Ninety-two patients had futile recanalization. Compared with the effective recanalization group, futile recanalization group had significantly older age, significantly higher hemoglobin A1c on admission, significantly longer time from puncture to vascular recanalization, significantly higher proportions of patients with hypertension history and poor collateral circulation, and significantly different severities of stroke and white matter hyperintensities (WMHs) and distribution of occlusive sites ( P<0.05). Multivariate Logistic regression analysis showed that age, history of hypertension, time from puncture to vascular recanalization, poor collateral circulation, severe WMHs, and moderate-severe stroke were independent risk factors for futile recanalization after EMT in patients with acute anterior circulation large vessel occlusion ( P<0.05). A nomogram model of futile recanalization was established according to the above 6 factors, with C-index of 0.862 ( 95%CI: 0.809-0.914); the calibration curve of the model was highly coordinated to the ideal model curve; area under the ROC curve of futile recanalization was 0.862 ( 95%CI: 0.809-0.914, P<0.001). Conclusions:Acute anterior circulation large vessel occlusion patients with older age, history of hypertension, longer time from puncture to vascular recanalization, poor collateral circulation, severe WMHs, and moderate-severe stroke trend to have futile recanalization after EMT. This nomogram can predict futile recanalization after EMT.

To enhance recombinant protein production by CHO cells, We compared the impact of overexpression of metabolic enzymes, namely pyruvate carboxylase 2 (PYC2), malate dehydrogenase Ⅱ (MDH2), alanine aminotransferase Ⅰ (ALT1), ornithine transcarbamylase (OTC), carbamoyl phosphate synthetase Ⅰ (CPSⅠ), and metabolism related proteins, namely taurine transporter (TAUT) and Vitreoscilla hemoglobin (VHb), on transient expression of anti-hLAG3 by ExpiCHO-S. Overexpression of these 7 proteins could differentially enhance antibody production. OTC, CPSI, MDH2, and PYC2 overexpression could improve antibody titer by 29.2%, 27.6%, 24.1%, and 20.3%, respectively. Specifically, OTC and MDH2 could obviously improve early-stage antibody production rate and the culture period was shortened by 4 days compared with that of the control. In addition, OTC and MDH2 had little impact on the affinity of anti-hLAG3. In most cases, overexpression of these proteins had little impact on the cell growth of ExpiCHO-S. MDH2 and ALT1 overexpression in H293T cells could also improve antibody production. Overall, overexpression of enzymes involved in cellular metabolism is an effective tool to improve antibody production in transient expression system.
