Objective:To study how to guide the individual dose of clopidogrel in line with the genetic testing results. Methods:Clinical pharmacists decided how to optimize the prescription of clopidogrel according to the genotype combined with the drug metabolism and drug interactions for three patients respectively with slow clopidogrel metabolism,intermediary metabolism and super fast metabolism. Results:The slow clopidogrel metabolism patient with subacute stent thrombosis after half a month of coronary stenting was switched to orally administrate with ticagrelor. The super fast metabolism patient suffered from repeatedly subcutaneous hemorrhage with antiplatelet therapy was suggested to lower the dose of clopidogrel,temporarily withdraw Maixuekang capsules and conventionally administrate with vitamin C tablets orally. The intermediary metabolism patient with late stent thrombosis co-treated with lansoprazole was suggested to increase the dose of clopidogrel or use ticagrelor instead,and when it was necessary,panxitorazole,ray Bella or the other ranitidine acid suppression drugs such as ranitidine could be considered. Conclusion:Through genetic testing and drug interactions,clinical pharmacists guide the clinical use of clopidogrel and the optimization of antiplatelet therapy.

BACKGROUND:Caffeic acid phenethyl ester (CAPE) can inhibit lipid peroxidation after rat brain injury. However, the trend of 5-lipoxygenaseis (5-LOX) and cysteinyl leukotrienes (CysLTs) in model of Parkinson’s disease, and whether CAPE protects against rotenone-induced cel ular injuries by inhibiting the levels of 5-LOX and CysLTs stil need further research.
OBJECTIVE:To investigate the protective effect of CAPE on the rotenone-induced Parkinson-like injury, and to determine whether 5-LOX involved.
METHODS:(1) PC12 cel s in good-growth were col ected and divided into five groups cultured with different concentrations of rotenone (0, 0.01, 0.1, 1, 10μmol/L). 24 and 48 hours later, changes of cel ular morphology and activity were observed to single out the optimum concentration of rotenone;at 24 hours, the levels of 5-LOX and CysLTs were detected by western blotting and ELISA, respectively. (2) PC12 cel s were pretreated with different concentrations of CAPE (0, 0.01, 0.1, 1, 10 μmol/L) for 30 minutes, and 1 μmol/L rotenone was then added. The other cel s received no intervention as blank control group. Subsequently, the cel activity was detected, and the CysLTs production was detected by ELISA at 24 hours.
RESULTS AND CONCLUSION:(1) Rotenone (0.1-10μmol/L) could induce PC12 cel injury with overt morphological and cel activity changes at 24 hours, especial y the 1 μmol/L rotenone. (2) Rotenone also significantly increased the 5-LOX expression and CysLTs production in a concentration-dependant manner. (3) CAPE (1-10μmo/L) significantly attenuated rotenone-induced CysLTs production and cel viability reduction in a concentration-dependant manner. (4) These results suggest that CAPE protects against PC12 cel injuries in the model rat with Parkinson’s disease induced by rotenone involving 5-Lox.

Objective To explore the prognostic value of ventricular wall motion score (WMS) and left ventricular ejection fraction (LVEF) in patients with acute myocardial infarction (AMI) combined with heart failure (HF) in the recent 12 months Methods We selected hospitalized AMI patients in our department from Jan. 2014 to Nov. 2014. Cardiac ultrasound was performed to detect WMS and LVEF within 48 hours and during the 6?month follow?up period and the occurrence of HF was recorded. Results Totally 127 AMI patients were recruited, including 20 cases combined with HF. The WMS was higher in HF group than those in non?HF group (23.55 ± 3.73 vs 20.11 ± 3.13, P<0.01), while the LVEF in HF group was lower than those in non?HF group (48.77 ± 8.08 vs 56.99 ± 5.17, P<0.01). Multiple logistic regression analysis revealed that WMS and LVEF were both independent predictors of HF in the recent 12 months (P < 0.05). The prediction effect of WMS ROC curve area was 0.81 (P < 0.01) , and LVEF 0.76 (P < 0.05). WMS and LVEF combined assessment area under ROC curve was 0.82 (P < 0.01). Conclusion WMS and LVEF are independent predictors of HF in patients with AMI in the recent 12 months and the combined application of WMS and LVEF can significantly improve the prediction effect.

Objective To explore the effects of electro-acupuncture combined with surface gastric pacing on gastrointestinal dysfunction for patients with spinal cord injury (SCI).Methods Seventy-five SCI patients with gastrointestinal dysfunction were divided randomly into an electro-acupuncture group (group A),a gastric pacing treatment group (group B) and a group for which electro-acupuncture was combined with gastric pacing (group C).There were 25 cases in each group.Members of group A were given 30 minutes of electro-acupuncture per day ; those of group B had 30 minutes of gastric pacing treatment twice per day ; group C was provided with both 30 minutes of electro-acupuncture and one 30-minute gastric pacing treatment per day.All of the interventions lasted ten days.Before and after the treatment,all patients were assessed using a clinical symptoms score and with electrogastrograms,and any adverse effects were observed.Results There was a significant improvement in upper abdominal pain and epigastric discomfort,bloating and early satiety,nausea,vomiting,as well as belching and loss of appetite in each group after treatment.Before treatment there was no significant difference in the average clinical symptom scores of the three groups.After treatment the values had decreased,and those of group C were significantly lower than group A or B.The average scores of groups B and A were not significantly different.The electrogastrogram results showed than after treatment there was significant improvement in N% and T% in groups A and B,and also significant improvement in N%,B% and T% in group C compared to before treatment.Group C's improvements were all significantly greater than those observed in groups A and B.Conclusion Electro-acupuncture or gastric pacing alone can give some improvement in gastrointestinal function and its electrophysiological indicators,but their combined effects are better than when either is used alone.

OBJECTIVETo evaluate the biomechanical properties of tibial plateau depressed fracture fixed with a net-fixation of Kirschner wires.
METHODSTwenty homemade fracture models were fixed with eight 1.5 mm Kirschner wires in a net-fixation; 20 homemade fracture models were fixed with two 3.5 mm cortical screws. Plane-compressed and dot-compressed test were made on each 10 models of the two groups. The maximal force of anti-ompress and stiffness were measured and evaluated.
RESULTSIn plane-compressed test,mean maximal force of anti-compress and stiffness for screw fixation was (1,925.31 +/- 444.26) N and (2.28 +/- 0.53) N/mm2, respectively, for net-fixation was (1,609.62 +/- 277.72) N and (1.90 +/- 0.33) N/mm2, respectively. There was no statistical difference between the two fixation methods (P > 0.05). In dot-compressed test,mean maximal force of anti-compress and stiffness for screw fixation was (411.13 +/- 233.88) N and (2.66 +/- 1.52) N/mm2,respectively,for net-fixation was (1,105.58 +/- 290.66) N and (7.18 +/- 1.89) N/mm2,respectively,the net-fixation was better than that of the screw fixation (P< 0.01).
CONCLUSIONTreatment of tibial plateau depressed fracture with a net-fixation of Kirschner wires is a biological fixation and is a reliably method.

At present, majority of the small molecular drugs used in clinics target proteins, they exert the efficacy through the binding to specific sites on the target protein. However, the "druggable" protein targets account for a small portion of the total number of proteins, and "non-druggable" proteins account for 80%, because of not having suitable drug binding sites. In the central rule, RNA is located in the upstream of proteins and controls the transcription of proteins. The research of small molecule drugs targeting RNA can solve the problem of protein "undruggable proteins" in some extent. This review summarizes the representative research achievements of small molecular drugs targeting RNA in recent years, and the screening methods applied to this field, with the focuses on the latest progress of small molecular drugs targeting novel coronavirus RNA.
