Investigation on the mechanism of anti-drug-induced liver injury and related effector substances of traditional Chinese medicine from the perspective of metabolism / 药学学报

Drug-induced liver injury (DILI) is one of the common clinical adverse drug reactions and remains a major cause of drug restriction, development termination and withdrawal from the pharmaceutical market today. In recent years, a variety of chemical components and metabolites of traditional Chinese medicine (TCM), as well as the endogenous effector substances influenced by metabolism of both, have attracted much attention for their significant hepatoprotective activities. However, the mechanism of TCM against DILI is complex, the related effector substances are still unclear, and its metabolism-related studies are still relatively weak. Therefore, this review summarized the mechanisms of DILI and its treatment by TCM from the perspective of metabolism, and for the first time, innovatively classified the Chinese medicine effector substances into two categories: exogenous (active components and metabolites of TCM) and endogenous (intestinal probiotics and endogenous metabolites), in order to reduce the occurrence of DILI, explore and develop effective anti-drug-induced liver injury effector substances of TCM, and further develop clinical drugs with hepatoprotective effects.

Investigation on Compatibility Characteristics and Mechanism of Baimai Ointment in Intervening "White Vein" by Integrating Bioinformatics Analysis and Prescription Rule Discovery / 中国实验方剂学杂志

Objective:To explore the mechanism and compatibility characteristics of Baimai ointment （BMO） in the treatment of white vein disease from the network perspective based on system theory， so as to provide biological basis for its clinical application. Method:The chemical components and the corresponding candidate target spectra of BMO were obtained from The Encyclopedia of Traditional Chinese Medicine （ETCM） and Integrative Pharmacology-based Research Platform of Traditional Chinese Medicine （TCMIP）. According to the clinicopathological characteristics of white vein disease， focusing on four diseases/symptoms including neuropathic pain， inflammatory pain， chronic pain and lumbar disc herniation root neuralgia， the gene sets related to white vein disease were collected in Human Phenotype Ontology （HPO）， DisGeNET and other databases， then the interaction network of the targets of active components in BMO-gene sets related to white vein disease was constructed. On this basis， the hub network nodes were selected and enriched for exploring the mechanism of four functional groups of BMO in the treatment of white vein disease such as Huoxue Tongluo group （Curcumae Longae Rhizoma， Moschus， Tronae）， Xingqi Zhitong group （Myristicae Semen， Nardostachyos Radix et Rhizoma， Acori Calami Rhizoma）， Wenjing Sanhan Tongluo group （Zingiberis Rhizoma， Zanthoxyli Pericarpium， Caraway） and Jianpi Wenshen Qianggu group （Actinolite， Glycyrrhizae Radix et Rhizoma）. Result:The enriched pathways of the four functional groups in BMO were mainly distributed in three modules of nervous system function， inflammation-immune system regulation and body energy metabolism， and each module was connected by common target genes especially had its own focus. Among them， the regulation of nervous system function in Huoxue Tongluo group and Xingqi Zhitong group could be summarized as Huoxue Buqi and Xingshen Kaiqiao. Xingqi Zhitong group and Jianpi Wenshen Qianggu group were mainly used to promote the operation of Qi， promote blood metaplasia， enhance immunity and maintain the regulation of inflammation-immune system. Jianpi Wenshen Qianggu group and Wenjing Sanhan Tongluo group mainly regulated body energy metabolism by invigorating the spleen and supplementing Qi as well as warm-heat medicine. The whole formula focused on the multi-dimensional and multi-level mechanism of BMO in the intervention of white vein disease. Each functional group emphasized its respective characteristics in nervous system function， inflammation-immune regulation， and body energy metabolism. Two types of networks analysis models complemented and verified each other. Conclusion:BMO plays a role in the treatment of white vein disease mainly by regulating the function of nervous system， maintaining the balance of inflammation-immune system and interfering with energy metabolism. The relevant research results can provide reference for the in-depth exploration of the mechanism of BMO， and help to guide the clinical rational use of this preparation.

Objective::To explore the clinical efficacy of Tongqiao Huoxuetang plus acupuncture on post-stroke cognitive impairment (PSCI) and its effect on neurotransmitters and neurological function of patients. Method::Totally 122 PSCI patients admitted in our hospital from January 2017 to March 2019 were randomly divided into observation group and control group by simple random number table method, with 61 patients in each group. Both groups were given oral donepezil hydrochloride tablets. The control group was given acupuncture treatment, while the observation group was given Tongqiao Huoxuetang plus acupuncture in addition to therapy of control group. All patients were treated continuously for 4 weeks. The clinical efficacy was compared between two groups. Before and after treatment, the general cognitive function of two groups was tested by mini-mental state examination (MMSE), changes of their neurologic impairment and daily living ability were evaluated by National institutes of health stroke scale (NIHSS) and Barthel index (BI) respectively, and euzymelinked immunosorbent assay was adopted to test the levels of neurotransmitters [acetyl choline (ACh), dopamine (DA), noradrenaline (NE), 5-hydroxytryptamine (5-HT)] and neurologic impairment markers [neuronspecific enolase (NSE), visinin-like protein-1 (VILIP-1), myelin basic protein (MBP)]. And the occurrence of adverse reactions was recorded. Result::The overall effective rate of the observation group was 91.8% (56/61), which was much higher than 78.7% (48/61) of control group (P<0.05). After treatment, both groups saw much higher MMSE and BI scores but lower NIHHS scores than before treatment (P<0.05), and above indicators in observation group were improved more significantly than those in control group over the same period after treatment (P<0.05). The levels of serum ACh, DA, NE and 5-HT after treatment were obviously higher than those before treatment (P<0.05), and observation group had significantly higher ACh, DA, NE and 5-HT levels than control group over the same period (P<0.05). After treatment, both groups witnessed a great decrease in NSE, VILIP-1, MBP (P<0.05), while the observation group saw dramatically lower NSE, VILIP-1, MBP levels than control group over the same period after treatment (P<0.05). Neither of two groups saw serious adverse reactions. Conclusion::In treating PSCI, Tongqiao Huoxuetang plus acupuncture can significantly improve neurological function of the patients, which may be due to increase of neurotransmitters.

Factors affecting the stability of carotid atherosclerotic plaque by left ventricular function / 医学研究生学报

Objective At present, there are few reports on the stability of carotid plaque and left ventricular function at home and abroad. The article investigated the factors influencing the stability of left ventricular function on carotid atherosclerotic plaque. Methods 90 patients with carotid atherosclerosis (carotid intima-media thickness >0.2 cm) admitted in the Department of Neurology, Jiangsu Provincial Hospital of Traditional Chinese Medicine from June 10, 2017 to January 8, 2019 were selected and their stability of plaques was graded by contrast-enhanced ultrasound (CEUS). The patients were divided into two groups according to the stability of plaque. The differences of general clinical data, related biochemical indexes and left ventricular function indexes between the two groups were compared. The effects of left ventricular structural function on plaque stability were examined by logistic multivariate regression analysis. Results Univariate analysis showed that E peak (χ2=2.170, P=0.034), ventricular septal thickness (χ2=-1.972, P=0.049), diabetes history (χ2=10.102, P=0.001) were the risk factors of plaque stability and the differences were statistically significant (P < 0.05). Multivariate analysis showed that E peak (OR=0.022, P=0.014) and diabetes history (OR=0.185, P=0.002) were independent influencing factors of plaque stability. Conclusion There is an independent correlation between left ventricular function and plaque stability, and plaque stability can predict changes in ventricular structural function.
