How to identify active constituents of traditional Chinese medicines (TCMs) and study their interactions are key problems in the development of TCMs. The inhibitory effect of six alkaloids from Rhizoma Coptidis (RC) on Shigella dysenteriae (S. dysenteria) growth had been investigated by microcalorimetry in this study. Main active constituents of RC were confirmed by comparing their contributions to the bacteriostatic effect, and the interactions among active constituents were further researched. According to the result, in 0.8 mg-mL-1 extract of RC, the contributions of six active alkaloids including berberine, coptisine, epiberberine, palmatine and the combination of jatrorrhizine and columbamine were 52.83%, 36.31%, 2.49%, 4.27% and 3.21%, respectively. Therefore, berberine and coptisine were the main active constituents of RC that inhibited the growth of S. dysenteria. The study of interactions among the six alkaloids indicated that, 1 there were some contstituents antagonizing the inhibitory effect of RC, 2 there was a synergy effect between berberine and coptisine, 3 there were additive effects between other four alkaloids and the main active constituents. These results may provide some useful references for the establishment of the quality standard for RC and the development of multi-component TCMs.

The study is to report the establishment of a method of screening the antitumor compounds based on the dynamic bio-response profile of cells to make up for the shortages of conventional end-point tests such as tedious operation and low sensitivity. Based on the principle of electric impedance of cells, the real-time cell electronic sensing (RT-CES) system was used to monitor the effect of epirubicin (EPI), cisplatinum (DDP) and carboplatin (CBP) on the growth of HepG2 cells, with the cell index (CI), half maximal inhibitory concentration (IC50) and detachment curve as evaluation indexes. Meanwhile, cell counting kit-8 (CCK-8) and microscopy were applied for verification. The results showed that CI curve could sensitively real-time profile the inhibitory effect of model drugs on HepG2 cells. The IC50 of EPI, DDP and CBP were 0.53 +/- 0.04, 9.79 +/- 0.26 and 597.00 +/- 3.79 microg x mL(-1), respectively. What's more, the significant differences of detachment curves of the three drugs indicated that their functional mechanisms might be different, this is consistent with the literature. The RT-CES system with non-invasive, label-free and real-time characteristics could be used to monitor the bio-response profile of the three drugs to HepG2 cells, allowing to qualitatively and quantitatively distinguish the antitumor activities of the three drugs, and could be a complementary method for the present screening of antitumor compounds.

This study aims at trying to establish a novel method of sterility test for injections based on biothermodynamics, in order to overcome the deficiencies of routine sterility tests such as long detecting cycle, low sensitivity and prone to misjudgments. A biothermodynamics method was adopted to rapidly detect the microorganism contamination of injections by monitoring the heat metabolism during the growth of microbe. The growth rate equal to or greater than zero and the heat power difference of P(i) and P(0) with three folds higher than the noise of baseline were chosen as indexes to study the heat change rule of microbe. In this way, the effectiveness of the new method to detect strains required by conventional sterility test or in injection samples was also investigated. Results showed that the Gram-positive bacteria, Gram-negative bacteria and fungi demanded by sterility testing methodology could be detected by biothermodynamics method within 10 hours, with the sensitivity lower than 100 CFU x mL(-1). Meanwhile, this method was successfully applied to the sterility test of Compound Yinchen injection (FFYC), Shuanghuanglian powder injection (SHL) and Compound Triamcinolone injection (TAND) which were sterilized with different degrees. Therefore, the biothermodynamics method, with advantages of fast detection and high sensitivity, could be a complementary solution for conventional sterility tests.

Delirium is a common complication after stroke. Post-stroke delirium is associated with the poor outcome and increased mortality. This article reviews the screening tools, predictive factors and predictive models of post-stroke delirium.

Objective:To construct a predictive model of post-stroke delirium (PSD) in patients with acute ischemic stroke (AIS), and to verify its predictive value.Methods:Patients with AIS admitted to the Department of Neurology, Lianyungang Hospital Affiliated to Xuzhou Medical University from February to May 2022 were enrolled prospectively. They were divided into modeling group and validation group according to the order of enrollment. Depending on whether the patients had delirium or not, the patients in the modeling group were divided into delirium group and non-delirium group. The independent risk factors for PSD were determined by multivariable logistic regression analysis, and the prediction model of PSD was constructed accordingly. The predictive value of the model was verified by the receiver operating characteristic curve. Results:Three hundred and fifty patients with AIS were included in the modeling group, of which 71 (20.28%) had PSD. The validation group included 150 patients with AIS, and 36 of them (24.00%) had PSD. Multivariate logistic regression analysis showed that age (odds ratio [ OR] 1.036, 95% confidence interval [ CI] 1.000-1.074; P=0.050], National Institutes of Health Stroke Scale (NIHSS) score ( OR 1.607, 95% CI 1.438-1.797; P<0.001), neutrophil/lymphocyte ratio (NLR) ( OR 1.135, 95% CI 1.016-1.267; P=0.025), and atrial fibrillation ( OR 5.528, 95% CI 1.315-23.245; P=0.020) were the independent risk factors for PSD. The predictive model was Z=0.036×age+0.475×NIHSS score+0.127×NLR+1.710×assignment of atrial fibrillation - 10.160. The area under the curve of the model was 0.935, and the sensitivity and specificity were 97.2% and 82.5% respectively. Conclusion:This model can effectively predict the PSD risk of patients with AIS, with higher sensitivity and specificity, and can provide a basis for PSD screening of patients with AIS.
