Objective To evaluate the changes of platelet aggregation rate and short-term prognosis after the application of colopidgrel with booster doses or replaced by ticagrelor for ACS patients with CYP2C19 medium-metabolized genotype). Method A total of 302 patients with medium-metabolized genotype were randomly divided into colopidgrel group (75 mg/bid) and ticagrelor group (90 mg/bid). Patients in both groups accepted other conventional treatments of coronary heart disease and accompanied diseases. The platelet aggregation rates and platelet inhibition rates were observed before and after the treatment. The incidence of adverse events was followed up within 1 m. Results After one-week treatment, the platelet aggregation rates of the inducement with 5 μmol/L ADP had statistical significance between colopidgrel group and ticagrelor group ( P = 0 . 019 ) and the platelet inhibition rates had statistical significance difference between the two groups (P = 0.000). No severe adverse events occurred within one-month follow-up and 10 dyspnea patients were all in ticagrelor group. Conclusions Compared with booster doses of clopidogrel, ticagrelor presents obvious inhibitory effect on platelet of patients with medium-metabolized of ACS but it increases the incidence of dyspnea.

B ased on Chinese medicine pharmacological literature data , the property , flavor , toxicity , meridian tropism, efficacy, and clinical application of Chinese herbal medicine were used as a set of attributes. The sup-port vector machine ( SVM ) was used in the establishment of predictive models of 187 pharmacological effects of Chinese herbal medicine respectively. And the cross-validation method was used to determine the accuracy of predictive models . After that , the predictive models with the predictive accuracy rate greater than 90% were used to predicate pharmacological effects of 624 herbals recorded in the Chinese Pharmacopoeia(2010 edition). It was found that the accuracy rate of 108 models was greater than 90%, and the accuracy rate of antibacterial effect predictive model was 99.76%. The highest predictive value of Chinese herbal medicine was the anti-oxi-dation effect of Menispermi Rhizoma.

Objective To investigate the diagnostic value and the efficacy of magnetic resonance tomographic angiography(MRTA) in identifying the relationship between nerves and blood vessels of the patients with idiopathic trigeminal neuralgia.Methods Clinical and MR data of 280 ITN patients were analyzed retrospectively,and then were compared with operation results by using blind con-trol trials.Results Of the 280 ITN patients,there were a total of 267 patients with neurovascular contact,dubious contact or com-pression in affected sides (positive rate:95.3%),and 66 patients in normal sides (false positive rate:23.6%).And of 120 surgical patients,1 18 were found to have neurovascular contact or compression during the operation.There was significant statistical differ-ence between the neurovascular contact or compression in affected sides and that in normal sides (P <0.05).Using operation results as the gold standard,the specificity,sensitivity and the diagnostic accordance rate of MRTA in diagnosing neurovascular contact or compression were 100%,96.6% and 96.7% respectively.Conclusion MRTA can reliably display the relationship between nerves and blood vessels with higher diagnostic sensitivity and accuracy,thus providing the objective basis for the etiological diagnosis of and surgical treatment for ITN.

OBJECTIVE:To prepare famotidine sodium chloride injection METHODS:The famotidine sodium chloride injection was prepared with aspartic acid as solutizing agent and sodium chloride injection as solvent The contents of famotidine and its related substances were determined by means of HPLC Influencing factor and the stability of famotidine were studied and the therapeutic effect was observed RESULTS:The content of famotidine was slowly reduced while temperature rising and time prolongine The content of famotidine was 98 6% at the end of the 6th month at 40℃ with accelerating experiment Its content was 98 4% after one year storage under room temperature Its content was 98 5% at the 10th day after illumination with 4 500Lx light in accelerating experiment The content of related substances was less than 2% The total effective rate was 93 75% CONCLUSION:Famotidine sodium chloride injection was stable in property and had definite therapeutic effect,and its clinical application was simple and free from contamination

Apolipoprotein A5(ApoA5)level and other indices were determined in patients with type 2 diabetes mellitus and healthy individuals.Compared to control group,ApoA5 level in the diabetic group was lower (P

Objective:To investigate the application of Xiyanping injections ( XYP) in the bone surgery department inpatients in a certain hospital to provide reference for the clinical rational medication. Methods:A retrospective investigation was adopted to randomly survey 180 hospitalized medical recorders with XYP from a certain hospital in 2013. The usage, dosage and medication purpose of XYP were analyzed. Results:The reasonable rate of usage and dosage of XYP was 97. 2%. Among the surgical patients, 82. 8% were giv-en XYP, and among them, 97. 3% was accordance with the medication purpose. Among the nonsurgical patients, 17. 2% were given XYP, and among them, 71. 0% was accordance with the medication purpose. The alone-use rate was 60. 0% and the rate of combina-tion with antibacterials was 40. 0%. The longest treatment course was 20d, the shortest one was 1 d, and the mean value was (7. 7 ± 5. 3) d. Conclusion:Irrational use of XYP exists in clinics, and the use should be strengthened and regulated.

Objective To evaluate the clinical efficacy and safety of domestic BuMA biodegradable drug eluting coronary stent in elderly coronary heart disease patients over 75 years old with shortened duration of clopidogrel treatment. Methods 100 elderly patients who received coronary angiography and PCI were included, and they were randomly divided into the observation group ( n=50, received oral clopidogrel for 9 months) and the control group (n=50, received oral clopidogrel for 12 months). The occurance of angina pectoris, AMI, bleeding events and the results of control angiography were compared between the two groups after 12 months of follow-up. Results All the 100 patients were followed up in 12 months after discharge. 4 patients ( 8. 0%) in the observation group and 3 patients ( 6. 0%) in the control group had recurrent angina. Control coronary angiography 12 months later showed no restenosis in the stents. There was no significant difference between the two groups in the recurrence of angina pectoris and coronary stent restenonsis. No acute myocardial infarction,cliniacl bleeding events and late stent thrombosis occurred in the two groups. Conclusions The application of the domestic BuMA biodegradable drug eluting stent for the treatment of coronary heart disease patients over 75 years old is safe and effective with shortened duration of clopidogel treatment.
