Objective:To determine the predictive role of combined assessment of vasoactive-inotropic score(VIS) and lactate for the prognosis of patients with postcardiotomy cardiogenic shock(PCS) requiring venoarterial extracorporeal membrane oxygenation(VA-ECMO).Methods:222 adults with PCS requiring VA-ECMO were retrospectively analyzed and divided into four groups according to the cut-off values of VIS and lactate(Lac) at 24 h after ECMO initiation: group 1(59 cases): VIS≤14.5, Lac≤2.45 mmol/L; group 2(17 cases): VIS>14.5, Lac≤2.45 mmol/L; group 3(90 cases): VIS≤14.5, Lac>2.45 mmol/L; group 4(56 cases): VIS>14.5, Lac>2.45 mmol/L. The incidence of in-hospital mortality and other clinical outcomes were analyzed. The associations of VIS and lactate and in-hospital mortality were analyzed using Cox proportional hazards analysis.Results:The in-hospital mortality was 18.6%, 58.8%, 63.3% and 71.4% in the four groups( P<0.001), while the rate of successful weaning off ECMO was 88.1%, 88.2%, 58.9% and 33.9% respectively( P<0.001). The group 1 significantly differed from other three groups with regards to in-hospital mortality and ECMO weaning rate( P<0.05). The groups 1 also showed significantly improved cumulative 60-day survival compared with other three groups( log- rank test, P<0.05). Cox proportional hazards analysis showed age( HR=1.03, 95% CI: 1.01-1.05, P=0.001), female( HR=1.87, 95% CI: 1.27-2.76, P=0.002), VIS at 24 h after ECMO initiation( HR=1.02, 95% CI: 1.00-1.05, P=0.020), and lactate at 24h after ECMO initiation( HR=1.12, 95% CI: 1.08-1.16, P<0.001) were independently predictive of in-hospital mortality. Conclusion:Patients with VIS≤14.5 and Lac≤2.45 within 24 h after ECMO initiation had better in-hospital and 60-day outcomes, suggesting that combined assessment of VIS and lactate may be instructive for determining the prognosis of PCS patients requiring VA-ECMO support.

Objective:To examine the long-term survival outcomes and identify mortality risk factors for coronary artery bypass grafting patients who received venoarterial extracorporeal membrane oxygenation(VA-ECMO) for postcardiotomy cardiogenic shock.Methods:Data from 121 consecutive venoarterial extracorporeal membrane oxygenation-treated coronary artery bypass grafting(CABG) patients at Beijing Anzhen Hospital between June 2012 and December 2016 were analyzed. There were 84 males and 24 females. The median age was 62(55, 67) years, and the median body mass index was 25(23, 27)kg/m 2. Thirty-seven patients(34%) had left main artery disease, and 56 patients(52%) underwent off-pump CABG. According to the 3 year survival outcome after ECMO, patients were divided into survival group(35 cases) and non-survival group(73 cases). The differences of clinical indicators between the two groups were compared and analyzed. Multivariable Cox regression modeling was used to identify factors independently associated with 36 month mortality. Results:Sixty-five patients(60%) could be weaned from VA-ECMO, 49 patients(45%) survived to hospital discharge, and 35 patients(32%) survived to 3 years. The median( IQR) time on VA-ECMO support was 4(3, 5) days. The median( IQR) length of ICU stay and hospital stay duration were 8(5, 12) and 20(13, 29) days, respectively. Older age( HR=1.06, 95% CI: 1.03-1.10, P<0.001), left main coronary artery disease( HR=1.62, 95% CI: 1.00-2.60, P=0.048), and vasoactive inotropic score( HR=1.09, 95% CI: 1.03-1.17, P=0.007)were independent risk factors associated with 3-year mortality. The area under the receiver operating characteristic curve for the model, which was constructed with age≥60years, left main coronary artery disease, and vasoactive inotropic score>60, was 0.88(95% CI: 0.80-0.95). Conclusion:Long-term survival of patients who survive to discharge appears favorable. Older age, left main coronary artery disease, and vasoactive inotropic score were associated with 3-year mortality in coronary artery bypass grafting patients who received VA-ECMO.

Tumor has become a major disease that seriously threatens human health and life. The incidence rate is increasing year by year， yet the underlying mechanisms remain incompletely understood. Traditional Chinese medicine （TCM）， a treasure of the Chinese nation and a wealth for people worldwide， plays an important role in the treatment of tumors and has been receiving increasing attention both in China and abroad. In earlier work， based on the symptoms and metastatic characteristics of tumors， and drawing on the TCM theory of Yin and Yang in combination with modern medical research on tumors， the ''Yin deficiency-cancer correlation'' hypothesis was proposed. This hypothesis holds that ''Yin deficiency'' of the body is a major cause of malignant tumors， and that nourishing Yin to eliminate the pathogenic factor of Yin deficiency can treat cancer. By using Yin-nourishing drugs to tonify Yin deficiency， the occurrence and development of malignant tumors can be effectively prevented. Common anti-tumor Yin-nourishing drugs include Glehniae Radix， Lilii Bulbus， Ophiopogonis Radix， Liriopes Radix， Asparagi Radix， Dendrobii Caulis， Dendrobii Officinalis Caulis， Polygonati Odorati Rhizoma， Polygonati Rhizoma， Lycii Fructus， Mori Fructus， Ligustri Lucidi Fructus， Ecliptae Herba， Rehmanniae Radix， and Anemarrhenae Rhizoma. These drugs are generally sweet in flavor， cold and cool in nature， and moist in texture. They have the functions of nourishing Yin fluids， generating body fluids， and moistening dryness， and can also clear heat， being primarily indicated for Yin deficiency with depletion of body fluids. In view of the potential advantages and value of treating malignant tumors by tonifying Yin deficiency with Chinese medicine， this paper reviews recent studies on the anti-tumor effects of active components of Yin-nourishing drugs. It further summarizes their mechanisms of action in inducing apoptosis of tumor cells， arresting tumor cell proliferation， inhibiting tumor invasion， metastasis， and angiogenesis， enhancing and regulating immune function， augmenting the efficacy of chemotherapeutic drugs， and reversing tumor drug resistance. This study provides an objective overview of research progress on Yin-nourishing drugs in tumor treatment and offers new ideas for cancer therapy.

The fingerprint of Boenninghausenia albiflora var. albiflora was established by ultra performance liquid chromatography(UPLC), and the content of 12 active components including chlorogenic acid was determined. Multivariate statistical analysis was used to explore the indicator components of B. albiflora var. albiflora and a comprehensive evaluation system was created for the quality of B. albiflora var. albiflora. In this study, 33 batches of B. albiflora var. albiflora with different sources were collected and studied, and the UPLC fingerprint of B. albiflora var. albiflora was developed. There were 37 common peaks, of which 12 components were identified, and the content of these 12 components was measured. In combination of the common peaks and the content of chemical components, multivariate statistical analysis was performed, and the results showed that 6 components [daphnoretin, isoimperatorin, astragalin, imperatorin, neochlorogenic acid, and isoquercitrin(weight coefficient>0.1)] were selected as chemical markers for the quality of B. albiflora var. albiflora. Technique for order of preference by similarity to ideal solution(TOPSIS) analysis and chemometrics revealed that the quality of S32, S28 and S29 were superior, while that of S12, S7 and S16 were inferior. The quality evaluation method of B. albiflora var. albiflora constructed in this study was accurate and reliable, with simpleness and easiness to operate. It is suggested that the 6 above-mentioned active components could be used as indicator components for quality control of B. albiflora var. al-biflora. The samples were harvested during the flowering and fruiting period, which is from the beginning of July to the end of August.
