Yinchenzhufu decoction (YCZFD) is a classic formula for treating Yin Huang syndrome, which can improve liver injury caused by cholestasis. However, the mechanism of action of YCZFD still remains unclear. This article used network pharmacology, molecular docking, animal experiments, and molecular biology methods to explore the mechanism of YCZFD in treating liver injury caused by cholestasis. A mouse model of acute cholestasis induced by lithocholic acid was used to investigate the effects of YCZFD on liver injury. The experimental procedures described in this paper were reviewed and approved by the Ethical Committee at the Shanghai University of Traditional Chinese Medicine (approval NO. PZSHUTCM190823002). The results showed that YCZFD could reduce the levels of blood biochemical indicators and improve hepatocyte damage of cholestatic mice. Then, multiple databases were used to predict the corresponding targets of YCZFD active components on cholestatic liver injury. An intersection target protein-protein interaction (PPI) networks based on String database and Cytoscape software was used to demonstrate the possible core targets of YCZFD against cholestatic liver injury. The results indicated that core targets of YCZFD include tumor necrosis factor, interleukin-1β, non-receptor tyrosine kinase Src, interleukin-6, etc. GO (gene ontology) and KEGG (kyoto encyclopedia of genes and genomes) enrichment analysis indicated that YCZFD may regulate the tumor necrosis factor signaling pathway, nuclear factor-κB signaling pathway, bile secretion, and other related factors to ameliorate the cholestatic liver injury. AutoDockTools software was used to perform molecular docking verification on the core targets and components of YCZFD. To verify the results of network pharmacology, UPLC-MS/MS method was used to determine the effect of YCZFD on levels of bile acid profiles in mouse liver tissues. It was found that treatment with YCZFD significantly reduced the content of free bile acids, taurine bound bile acids, and total bile acids in the liver tissues of cholestatic mice. Then, results from real time PCR and Western blot also found that YCZFD can upregulate the expression of hepatic nuclear receptor farnesoid X receptor, metabolizing enzyme (UDP glucuronidase transferase 1a1), and efflux transporters (bile salt export pump, multidrug resistance-associated protein 2, multidrug resistance-associated protein 3, etc) in cholestasis mice, promote bile acid metabolism and excretion, and improve bile acid homeostasis. Moreover, YCZFD can also inhibit pyroptosis and inflammation by regulating NOD-like receptors 3 pathway, thereby inhibiting cholestatic liver injury.

Prepulse inhibition ( PPI) is the suppression of the startle reflex when the startling stim-ulus is preceded by a non-startling stimulus ( the prepulse) . It is an operational measurement of sensorimotor gating mechanism to help the brain adapt to the complex environment,which could be top-down modulated by attention and other higher cognitive processes. Deficits of PPI and the top-down modulation of PPI are closely related to psychiatric diseases. Research papers published from January 2001 to October 2016 related to PPI in psychiatric disorders were searched in the Chinese and English databases. Results showed that schizo-phrenic patients and their relatives showed deficits in baseline PPI as well as the attentional modulation of PPI,and more importantly,the attentional modulation of PPI rather than the baseline PPI was more related to the symptom severity. Patients with Tourette'' s syndrome showed PPI impairment,while patients with obsess-ive compulsive disorder had lower levels of PPI. PPI deficits in bipolar disorder patients were gender-depend-ent. Studying PPI and the top-down modulation of PPI could provide a basis to study the interaction of senso-ry processing and attention,and facilitate the researches of neural mechanism underlying the deficits of senso-ry gating. To establish advanced paradigms of PPI,new cognitive components could be introduced,such as at-tention,emotion,motor control,compulsivity and so on,thus improving the specificity of PPI test and promo-ting the PPI test as new biomarker and endophenotype in various psychiatric disorders.

Streptozotocin-induced diabetic rats were treated with GSH for 12 weeks.The results showed that GSH significantly improved the expressions of NF-KB and inducible nitrie oxide synthase and ameliorated the myocardial tissue injury.

Objective: To investigate the anticancer action of taurine and its potential mechanisms. Methods: 101 weanling female SD rats were randomly divided into four groups. They were:(1)control group (CL):fed a basic diet;(2)high fat group(HF):fed a high fat diet (10% lard);(3)taurine group (Tau):fed a taurine diet (5% taurine);(4)taurine and high fat group(TH):fed a mixed diet (5%taurine and 10% lard). 10mg DMBA were given to each rat by gavage at age of 6 weeks. Then the rats were fed assigned diet for 26 weeks. By 5 weeks after DMBA administration the rats were palpated once weekly and the time, size, location of each tumor were recorded. The examinations made at the end of experiment were listed below: CI, LTT, serum antibody, SOD, MDA, GSH Px, TC, TG, LDL C. Results: The tumor incidence in group HF rats was higher than that in group CL, Tau and TH rats (P

Objective To observe the relationship of awake bispectral index (BISawake) and the postoperative cognitive dysfunction (POCD). Methods 100 patients aged 60~75 years with ASA status Ⅰ~Ⅱ, underwent elective lower abdominal surgery with intravenous anesthesia (propofol, remifentanyl and rocuronium). The BIS was adjusted in 40~60 during the surgery. Their cognitive function was assessed with the neuropsychological test battery commended by International study of postoperative cognitive dysfunction (ISPOCD). Results 8 patients withdrew for unwilling or serious complications. The BISawake was more than 65 in 68 patients (group A), and less than 65 in 24 patients (group B). The difference of the verbal learning immediate and delayed of Hopkins Verbal Learning Test-Revised was more in the group B than in the group A. Conclusion Lower BISawake may be associated with the decline of postoperative cognitive function.

Buluo Buguan Decoction originates from ZHANG Xi-chun's book Yi Xue Zhong Zhong Can Xi Lu, with the functions of astringent, removing blood stasis, and vein relaxing. The original major functions of this decoction are to treat chronic hemoptysis and hematemesis. In long-term clinical practice, Professor SHAO found that the modified decoction showed significant positive outcome in the treatment of hematuria, nocturnal emission, spontaneous sweating, night sweats, and allergic purpura nephritis, with good efficacy.

Objective:To evaluate the clinical application of 64-slice spiral computer tomography pulmonary angiography (CTPA)in diagnosis of pulmonary embolism(PE).Methods:Sixty-two patients suspected of PE were examined by 64-slice spiral CTPA.The image findings combined with their clinical data were retrospectively analyzed.Results:Twenty-four of the 62 patients were confirmed to have PE by clinical data,laboratory examination and follow-up examination.64-slice spiral CTPA discovered 152 involved branches in the 24 PE patients,including 4 branches in left and right pulmonary trunk,52 in lobar pulmonary arteries,82 in segmental pulmonary arteries,and 14 in subsegmental arteries.Four types of PE were detected in our group,including eccentric filling defect in 58 branches,central filling defect in 49 branches,total occlusion of the pulmonary arteries in 21 branches,and mural embolism of host artery in 24 branches.The diagnosis accuracy of 64-slice spiral CTPA in the present group of patients was 100%,with no missed diagnosis and misdiagnosis.Besides,64-slice spiral CTPA could reflect the location,morphology,involvement and degrees of PE.Conclusion:64-slice spiral CTPA is a rapid,accurate and non-invasive diagnostic approach for PE.It is the first choice in clinical screening of PE and may serve as a gold standard for diagnosis of pulmonary embolism.
