Objective To analyze the conditions of antithrombotic therapy in patients with atrial fibrillation (AF)and provide reference for clinical rational use of drugs.Methods The clinical data of 1 69 hospitalized patients with AF from July 201 4 to September 201 4 in Beijing Tongren Hospital affiliated to Capital Medical University were retrospectively analyzed.The risk stratification for thromboembolism,types of AF,drug selection,drug combination and adverse reactions were analyzed.Results In 1 69 patients with AF,the proportion of valvular AF was 1 4.20%(24 /1 69)and non -valvular AF was 85.80%(1 45 /1 69),the patients with AF aged over 60 years old accounted for 84.62%.In the antithrombotic therapy,warfarin accounted for 94.87% (74 /78),the average daily dosage was (2.51 4 ±0.842)mg,the cases with INR between 2.0 to 3.0 accounted for 41 .89%(31 /74).The incidence rate of adverse reactions was 2.56%(2 /78).Conclusion The antithrombotic therapy is obviously insufficient,the clinical pharmacists should analyze the factors which influence the treatment and promote the rational use of antithrombotic therapy in AF patients.

CXCL12,also known as stromal cell-derived factor 1,is a member of the CXC family,which locates on the 10th chromosome and produces by the stromal cells.It is known that CXCR4 and CXCR7 are the two receptors of chemokine CXCL12.Many studies show that the chemokine CXCL12 plays an important role in cancer progression,including proliferation,metastasis and angiogenesis.Therefore,the chemokine CXCL12 is expected to become a novel target for the gene therapy of cancer.

OBJECTIVE:To explore the content and mode of pharmaceutical care for patients with acute coronary syndrome (ACS). METHODS:Taking pharmaceutical care for 4 ACS patients as example,the contents of pharmaceutical care provided by clinical pharmacists during ACS treatment were summarized involving antiplatelet drugs,anticoagulant,anti-myocardial ischemia drug,statins. RESULTS:Through pharmaceutical care,clinical pharmacists found and resolved ADR during ACS treatment timely. The symptoms of patients were improved. CONCLUSIONS:Clinical pharmacists provide reasonable suggestion for ACS treatment to guarantee safe,reasonable and effective use of drugs in the clinic.

Objective To investigate the impact of propofol and midazolam on the time course of extubation in patients with mechanical ventilation.Methods The patients were randomly divided into the propofol group(n=37)and the midazolam group(n=52),which were further divided into three sedation stratums.The administration of two drugs were stoped immediately while weaning from the ventilator.The awakening time and extubation time of the two groups were recorded and compared with each other.Results Both awakening time and extubation time of the propofol groups were shorter than those of the midazolam group(P

Objective To optimize the formulation of sinomenine hydrochloride pulsatile drug delivery tablets by central composite design-response surface method.Methods The tablets containing sinomenine hydrochloride were prepared by dry-compression coating technique.The influence factors included the amount of sodium carboxymethyl starch in core tablets, the ratio of HPMC/carrrageenan,and the amount of matrix materials in coating film.The evaluation parameter was lag time.Experiments were done on the central composite design,and the data were simulated using multi-linear equation and second-order polynomial equation.The possibly optimal formulation was predicted by response surface method.The lag time of the tablets prepared under the optimum condition was compared with the predicted.Results The lag time was simulated using second-order polynomial equation and the regression coefficient was 0.993 7.The lag time in vitro of the tablets prepared under the optimum conditions was about 6 h,then drug released in pulsatilerelease character.Bias between the observed and predicted values of the lag time was within ?4.43%.Conclusion The sinomenine hydrochloride pulsatile tablets could release drug quickly in vitro at the predetermined time.Central composite design-response surface method can be used to optimize the formulation and the model developed in this study proves to be highly predictable.
