Objective To evaluate the effects of different sedation depths of propofol on postopera-tive delirium in patients undergoing cardiac valve replacement under cardiopulmonary bypass(CPB)and the relationship with regional cerebral oxygen saturation(rSO2). Methods Forty American Society of An-esthesiologists physical statusⅢorⅣpatients of both sexes, aged 26-64 yr, with body mass index of 17-25 kg∕m2, scheduled for elective aortic valve replacement with CPB, were divided into A and B groups (n=20 each)using a random number table. The infusion rate of propofol was adjusted to maintain the cor-responding anesthetic depth with 50≤BIS value<60 during CPB in group A and with 35≤BIS value<45 during CPB in group B. Bilateral rSO2was measured using the near infrared spectroscopy from admission to the operating room until the end of skin suturing. The minimum rSO2was recorded, and occurrence of low cerebral oxygen saturation(rSO2was less than 55% or the decrease in rSO2>20% of the baseline)was ob-served. Postoperative delirium was evaluated using Confusion Assessment Method for the Intensive Care Unit (ICU)from 12 h after admission to ICU until discharge from ICU. Results The incidence of postoperative delirium, low cerebral oxygen saturation and minimum rSO2were significantly lower in group B than in group A(P<005). Conclusion Maintaining 35≤ BIS value< 45 during CPB can reduce the develop-ment of postoperative delirium and is related to improving intraoperative rSO2in patients undergoing cardiac valve replacement.

Objective:To evaluate the effect of sedation management based on visual analysis of electroencephalography (EEG) on postoperative delirium in patients undergoing cardiac valve replacement with cardiopulmonary bypass (CPB).Methods:Eighty patients, aged ≥ 18 yr, of American Society of Anesthesiologists physical status Ⅲ or Ⅳ, with New York Heart Association Ⅱ-Ⅳ, scheduled for elective cardiac valve replacement with CPB, were randomly divided into visual analysis of EEG-guided sedation management group (group A, n=40) and BIS-guided sedation management group (group B, n=40). The target plasma concentration of propofol was adjusted to maintain the depth of anaesthesia at grade C or grade D in group A and BIS value at 40-60 in group B. Propofol consumption during CPB and total consumption of propofol during surgery, requirement for vasoactive agents during surgery, and parameters of intraoperative arterial blood gas analysis were recorded.Postoperative delirium was evaluated using Confusion Assessment Method for the Intensive Care Unit (ICU) at 1-7 days after surgery.Extubation time, length of ICU stay, length of postoperative hospital stay and intraoperative awareness were also recorded. Results:Compared with group B, the length of postoperative hospital stay was significantly shortened, the incidence of postoperative delirium was decreased, and no significant change was found in the parameters of arterial blood gas analysis, propofol consumption, requirement for vasoactive agents, extubation time, or length of postoperative ICU stay in group A ( P<0.05). No intraoperative awareness occurred in both groups. Conclusion:Sedation management based on visual analysis of EEG is helpful in decreasing the development of postoperative delirium in the patients undergoing cardiac valve replacement with CPB.

OBJECTIVE:
The compatibility of Eucommia ulmoides (Eu) and Psoralea corylifolia (Pc) on the pharmacokinetic (PK) properties in the rat was explored in this study.
METHODS:
Eu extract, Pc extract and the combined extracts (crude drug ratio was 2:1) was administered by gavage, respectively. Two PK experiments were conducted. In first one, the blood samples were collected via the occuli chorioideae vein to get the PK properties of the components. In second one, the blood samples were simultaneously collected via the internal jugular vein or portal vein at different time points and the concentrations of target ingredients were detected by LC/MS/MS to clear the location where the interaction of Eu and Pc took place in vivo.
RESULTS:
Eight of 11 ingredients in Eu and Pc extract were determined in rat plasma. The exposure levels of geniposidic acid (GPA), aucubin (AU), geniposide (GP), pinoresinol diglucoside (PDG), psoralen glycosides (PLG) and isopsoralen glycosides (IPLG) were decreased 1/5-2/3 after administration of combined extracts. Comparing to the combined administration, the exposure of GPA and AU in plasma of single Eu administration collected via the portal vein were decreased 1/3-2/3, and the values of AUC0-24h and AUC0-∞ of GP collected from the portal vein or internal jugular vein were double increased. The other components' parameters were not significantly changed.
CONCLUSION
In summary, the Pc and Eu combined administration could affect the exposure of the main components of Eu extract in rats due to the changed intestinal absorption. The research on the compatibility of Pc and Eu was helpful to guide the clinical administration of Eu and Pc simultaneously.

ObjectiveTo analyze the clinical application hotspots, development trends, compatibility characteristics, application rules, and formulation mechanisms of the Chinese marine drug pair Haliotidis Concha-Oystreae Concha in order to provide references for its clinical medication and further research. MethodBy means of various modern literature databases such as China National Knowledge Infrastructure (CNKI), modern clinical prescriptions containing Haliotidis Concha-Oystreae Concha, as well as the clinical application hotspots, were retrieved, followed by visualized analysis of hotspots and development trends of their clinical applications using Citespace. The drug composition, efficacy and indications, and drug dosages in the prescriptions were statistically analyzed. Additionally, various statistical software including SPSS Modeler 18.0 were employed to analyze the indications, syndromes, and formulation rules of Haliotidis Concha-Oystreae Concha. ResultThe visualized analysis included 90 articles, revealing a gradual decrease in publications in this field in recent years. Key clinical application keywords were identified as hypertension, collateral deficiency producing wind, insomnia, etc. Eighty clinical prescriptions were retrieved, involving 121 drugs. Frequency analysis of compatibility demonstrated that the top 10 drugs were Uncariae Ramulus cum Uncis, Gastrodiae Rhizoma, Os Draconis, Achyranthis Bidentatae Radix, Paeoniae Radix Alba, Chrysanthemi Flos, Scutellariae Radix, Gardeniae Frucuts, Glycyrrhizae Radix et Rhizoma, and Polygoni Multiflori Caulis. Association rule analysis showed that core combinations included "Uncariae Ramulus cum Uncis-Achyranthis Bidentatae Radix" and "Os Draconis-Pheretima-Chuanxiong Rhizoma". Through factor reliability analysis, new drug combinations were derived, such as "Gastrodiae Rhizoma-Polygoni Multiflori Caulis-Eucommiae Cortex-Taxilli Herba-Leonuri Herba", "Achyranthis Bidentatae Radix-Uncariae Ramulus cum Uncis", "Scutellariae Radix-Glycyrrhizae Radix et Rhizoma-Margarita-Prunellae Spica", "Os Draconis-Pheretima-Bombyx Batryticatus", "Chrysanthemi Flos-Chuanxiong Rhizoma", "Poria-Acori Tatarinowii Rhizoma", and "Paeoniae Radix Alba-Gardeniae Fructus-Sclerotium Poriae Pararadicis". The Haliotidis Concha-Oystreae Concha drug pair was mainly used to treat diseases with liver Yang hyperactivity syndrome, with hypertension accounting for 40.00%, migraines for 30.00%, and dizziness for 15.00%. In the treatment of liver Yang hyperactivity syndrome, the main categories of compatible drugs were liver-pacifying and wind-extinguishing ones (19.86%), blood-activating and stasis-resolving ones (12.13%), and spirit-calming ones (10.08%). High-frequency drugs in the prescriptions function to reduce blood pressure through multiple pathways, such as increasing nitric oxide (NO) levels, downregulating angiotensin Ⅱ (Ang Ⅱ), and inhibiting angiotensin-converting enzyme (ACE). ConclusionThrough comprehensive analysis of the results, the Haliotidis Concha-Oystreae Concha drug pair is commonly used for hypertension with liver Yang hyperactivity syndrome, and is often combined with deficiency-tonifying, liver-pacifying and wind-extinguishing, heat-clearing, and spirit-calming drugs, aiming to simultaneously extinguish wind, relieve spasms, and pacify the liver to subdue Yang, while also clearing heat to relax bowels, stabilizing the mind, and enhancing the liver-pacifying and Yang-subduing effects of this drug pair.

OBJECTIVE:
Hypertension is a low-grade inflammation state of the disease and was easily complicated by kidneys' inflammatory response. Mangiferin (MGF), a pharmacologically active compound in various plants including Mangifera indica, has a strong anti-inflammatory activity. However, the effects of MGF on renal inflammatory injury in spontaneously hypertensive rats (SHRs) remain unclear. The purpose of this study was to investigate the protective effects and mechanisms of MGF on renal inflammatory injury in SHRs.
METHODS:
MGF was used in SHRs at the doses of 10, 20, 40 mg/kg/d for 8 weeks consecutively. The blood and urine were collected for assessment of renal function. Renal tissues were collected for histological, immunohistochemistry, ELISA, Western blot and real time reverse transcription PCR (RT-PCR) analysis.
RESULTS:
The results showed that the levels of interleukin 6 (IL-6), tumor necrosis factor-α (TNF-α), monocyte chemoattractant protein-1 (MCP-1) and recombinant chemokine C-C-Motif receptor 2 (CCR2) were increased in SHRs, meanwhile, the level of IL-10 was decreased in SHR. Treatment of MGF inhibited the expression of IL-6, TNF-α, MCP-1 and CCR2, and promoted the expression of IL-10. Furthermore, the content of blood urea nitrogen (BUN) and serum uric acid (SUA) was significantly increased in the model group, and treatment of MGF had no obvious effects on these parameters at all dose levels.
CONCLUSION
Our study proved that the kidneys of SHRs had significant inflammatory injury, and MGF had the protective effects on renal inflammatory injury in SHRs; The protective mechanism may be mediated partly by the MCP-1/CCR2 signaling pathway. Thus, it is a potential new drug for the treatment of hypertension.

Zedoary tumeric (Curcumae Rhizoma, Ezhu in Chinese) has a long history of application and has great potential in the treatment of liver cancer. The antiliver cancer effect of zedoary tumeric depends on the combined action of multiple pharmacodynamic substances. In order to clarify the specific mechanism of zedoary tumeric against liver cancer, this paper first analyzes the mechanism of its single pharmacodynamic substance against liver cancer, and then verifies the joint anti liver cancer mechanism of its “pharmacodynamic group”. By searching the research on the antihepatoma effect of active components of zedoary tumeric in recent years, we found that pharmacodynamic substances, including curcumol, zedoarondiol, curcumenol, curzerenone, curdione, curcumin, germacrone, β-elemene, can act on multi-target and multi-channel to play an antihepatoma role. For example, curcumin can regulate miR, GLO1, CD133, VEGF, YAP, LIN28B, GPR81, HCAR-1, P53 and PI3K/Akt/mTOR, HSP70/TLR4 and NF-κB. Wnt/TGF/EMT, Nrf2/Keap1, JAK/STAT and other pathways play an antihepatoma role. Network pharmacological analysis showed that the core targets of the “pharmacodynamic group” for anti-life cancer are AKT1, EGFR, MAPK8, etc, and the core pathways are neuroactive live receiver interaction, nitrogen metabolism, HIF-1 signaling pathway, etc. At the same time, by comparing and analyzing the relationship between the specific mechanisms of pharmacodynamic substance and “pharmacodynamic group”, it is found that they have great reference significance in target, pathway, biological function, determination of core pharmacodynamic components, formation of core target protein interaction, in-depth research of single pharmacodynamic substance, increasing curative effect and so on. By analyzing the internal mechanism of zedoary tumeric pharmacodynamic substance and “pharmacodynamic group” in the treatment of liver cancer, this paper intends to provide some ideas and references for the deeper pharmacological research of zedoary tumeric and the relationship between pharmacodynamic substance and “pharmacodynamic group”.
