The evolving practice of precision medicine allows physicians to make disease treat-ments and prevention decisions based on a patient's individual genetic and molecular profile.In recent years,gene sequencing and related techniques are becoming more affordable and more accessible to healthcare providers,and their use in various medical fields continues to expand.In particular,there are numerous opportunities for the use of precision medicine in the perioperative setting.For example, individual polymorphisms in alpha and beta adrenergic receptors can improve the efficacy of beta blockade,or predispose a patient to adverse drug reactions including hypotension and bradycardia. Likewise,particular polymorphisms in opioid receptors can increase or decrease the effectiveness of various opioid medications for achieving adequate postoperative analgesia.In addition,mutations in the cytochrome P4502D6 (CYP2D6)enzyme can drastically affect the clinical response to a particular subset of beta blockers and opioids by accelerating or decelerating their metabolism and clearance. Preoperative genetic testing would allow anesthesiologists to identify these and other relevant molecu-lar characteristics in their patients,and choose appropriate perioperative therapies accordingly in order to maximize clinical outcomes while minimizing the incidence of adverse events.It is the time for anes-thesiologists and perioperative care providers to practice precision medicine.

ObjectiveTo study the effect and safety of flurbiprofen cataplasm on osteoarthritis pain in Chinese patients.MethodsOne hundred and eighty-three patients were divided into flurbiprofen cataplasm group,indometacin cataplasm group and Qizheng-xiaotong plaster group randomly.The score of pain,stiffness and physical function were analyzed with WOMAC scale and adverse reactions were also assessed.KruskalWallis H test,Nemenyi test and CMH tese were used.ResultsAfter treatment,the VAS value of the three groups decreased significantly and the VAS difference value of the flurbiprofen cataplasm group changed the most significantly(the changes of VAS value in flat walking,up and down stairs,nighttime,rest and weightbearing were 31±21,35±20,24±19,20±18 and 37±20 respectively).Meanwhile,the value of stiffness and physical function decreased significantly.In terms of safety,flurbiprofen cataplasm group and the indome-tacin cataplasm group were better than Qizheng-xiaotong plaster group.But in sense of constriction,the flurbiprofen cataplasm group was better than the indometacin eataplasm group.ConclusionFlurbiprofen Cataplasm,with its favorable analgesic effect,is suitable for general clinical use.It can reduce stiffness,improvephysical function,and has good safety profile.

Objectives: : Tianeptine is an antidepressant that has drawn attention recently. Unlike traditional monoaminergic antidepressants, tianeptine is known to affect glutamate neurotransmission like ketamine. However, there has been paucity of studies investigating the role of tianeptine on glutamate transporters, especially excitatory amino acid transporter type 3 (EAAT3). Methods: : After expression of EAAT3 by intracellular injection of EAAT3 mRNA, we investigated the effect of tianeptine on the activity of EAAT3, by measuring membrane current in response to L-glutamate administration using Xenopus oocyte expression system and two-electrode voltage clamps.. Results: : Tianeptine (1mM for 72h) significantly reduced Vmax (6.9±0.6 vs. 4.8±0.3mC, n=14-22, p<0.05) without changing Km (27.0±7.6 vs. 23.3±4.9mM, n=14-22, p=0.72). Conclusion : When tianeptine was exposed for 72h, it decreased the activity of EAAT3 in a concentration-dependent manner (1-100mM). Our results suggest that tianeptine decreases EAAT3 activity by reducing the available number or turnover rate of EAAT3.
