Progress of Brain Network Studies on Anesthesia and Consciousness: Framework and Clinical Applications

Although the relationship between anesthesia and consciousness has been investigated for decades, our understanding of the underlying neural mechanisms of anesthesia and consciousness remains rudimentary, which limits the development of systems for anesthesia monitoring and consciousness evaluation. Moreover, the current practices for anesthesia monitoring are mainly based on methods that do not provide adequate information and may present obstacles to the precise application of anesthesia. Most recently, there has been a growing trend to utilize brain network analysis to reveal the mechanisms of anesthesia, with the aim of providing novel insights to promote practical application. This review summarizes recent research on brain network studies of anesthesia, and compares the underlying neural mechanisms of consciousness and anesthesia along with the neural signs and measures of the distinct aspects of neural activity. Using the theory of cortical fragmentation as a starting point, we introduce important methods and research involving connectivity and network analysis. We demonstrate that whole-brain multimodal network data can provide important supplementary clinical information. More importantly, this review posits that brain network methods, if simplified, will likely play an important role in improving the current clinical anesthesia monitoring systems.

Clinical Application Analysis of Andrographolide Total Ester Sulfonate Injection,a Traditional Chinese Medicine Licensed in China

Andrographolide total ester sulfonate（ATES） injection is one of the products of traditional Chinese medicine（TCM） currently used against viral infection in China.ATES injection was approved for manufacturing and marketing in January 2002.It is indicated for acute respiratory infections,tonsillitis,chronic obstructive pulmonary disease,influenza,foot and mouth disease,bronchiolitis,herpangina,mumps,infectious mononucleosis and psychosis.However,its usage also carries risk.We investigated the use of ATES at the Wuhan Union Hospital from January 2014 to December 2014 and evaluated its real-world clinical application using the hospital centralized monitoring method.A total of 848 cases were enrolled in this study.In these cases,it was mainly used for postoperative anti-inflammation and treating upper respiratory infection,pneumonia and bronchitis.Among them,39.86% were contraindicated.Irregular medication of adults and children accounted for 1.91% and 23.38%,respectively.Improper choice of solvent accounted for 3.18%.The choice of intravenous drip versus aerosol inhalation was reasonable.A case of adverse events（AEs） was observed in the monitoring period,and the incidence of adverse drug reaction（ADR） of ATES injection was 0.12%.ATES injection in our hospital is relatively safe with a low incidence of adverse reactions.The study assesses the clinical usage and adverse reactions of ATES injection,and provides suggestions for rational use in clinical practice.

CLINICAL VALUE OF URINARY AND SERUM PSEUDOURIDINE IN DIAGNOSIS AND MONITORING OF PRIMARY LIVER CANCER

Urinary and serum pseudouridine concentrations were determined by high-performance liquid chromatography in 80 patients with primary liver cancer, 32 with benign space occupying lesions of the liver, 42 with liver cirrhosis and 40 healthy subjects. Their mean urinary and serum pseudouridine levels were 39.2=11.5 nmol / /μmol creatinine and 3.4 ± 1.3 μmol / L, 24.5 = 5.4 nmol / μmol creatinine and 2.5 = 0.5 μmol / L, 22.8 ± 7.8 nmol / μmol creatinine and 2.3 = 0.4 μmol / L, 26.4 ± 4.6 nmol / μmol creatinine and 2.3 = 0.4 μmol / L, respectively. Exceeding the mean plus 2SD of pseudouridine of healthy control was considered as positive value for the diagnosis of primary liver cancer. Thus the positivity of urinary and serum pseudouridine in hepatoma was 71.3% and 70.0%, respectively. The positive rate of combined pseudouridine and alpha-fetoprotein assay was 91.3% in patients with hepatoma. Besides, pseudouridine levels could elevate before positive localization and reduce to normal levels after tumor resection. The results showed that the determination of pseudouridine is of clinical significance in the diagnosis and monitoring of primary liver cancer.

Analysis for the vancomycin plasma concentration data in infants by clinical pharmacists

In the present study, clinical pharmacists monitored the blood concentration of vancomycin in children in the Infant Ward from 2013 to 2014, and the drug dose was adjusted according to its plasma concentration. Moreover, we analyzed the plasma concentration of vancomycin in infants in the hospital from 2013 to 2014. Simultaneously, we also discussed the necessity of regular therapeutic drug monitoring of vancomycin in infants, and the important role of clinical pharmacists was further explored. The results showed that it was necessary to routinely monitor the therapeutic drug in infants. Clinical pharmacists performed medication monitoring, which improved the effectiveness of vancomycin and prevented its adverse effects. In addition, it is a new treatment model for the participation of clinical pharmacists in the clinical treatment.
