The rapid mutation and widely spread of duck hepatitis A virus (DHAV) lead to the vast economic loss of the duck industry. To prepare and evaluate bivalent inactivated vaccine laboratory products of DHAV, 6 strains were screened from 201 DHAV-1 strains and 38 DHAV-3 strains by using serotype epidemiological analysis in most of the duck factory. Vaccine candidate strains were selected by ELD50 and LD50 tests in the 6 strains. Continuously passaged, the 5th passaged duck embryos bodies grinding fluid was selected as vaccine virus seeds. The virus seeds were treated with formaldehyde and water in oil in water (W/O/W) emulsions, making into three batches of two bivalent inactivated vaccine laboratory products. The safety test, antibody neutralization test, challenged protection and cross immune protection experiment suggested that the vaccines possessed good safety, and neutralizing antibodies were detected at 7th day and the challenged protection rate reached 90% to 100% at the 14th and 21st day. Moreover, immune duration of ducklings lasted more than five weeks. However, cross-immunity protection experiments with DHAV-SH and DHAV-FS only had 20%-30%. The two bivalent inactivated vaccine laboratory products of duck viral hepatitis were effective and reliable, providing a new method as well as a new product for DHAV prevention and control.

Objective: To discuss the pharmaceutical care experience of clinical pharmacists in the antibacterial agents application in one patient with infection after coronary artery bypass graft ( CABG) . Methods:The clinical pharmacist participated in the treatment of the patient after CABG. According to the relevant laboratory indices and the extent of the infection combined with the vital signs of the patient, the pharmacist formulated and adjusted the anti-infection therapeutic regimen. The therapeutic effects and adverse reactions were observed as well. Results: Safte and high-quality individualized pharmaceutical service was provided to the patient by the pharmaceutical care of the clinical pharmacist in anti-infection treatment. Conclusion:Through the above practice, clinical pharmacists have played a positive role in reasonable using of anti-infective drugs in patients with cardiac surgery.

OBJECTIVE:To explore the methods of clinical pharmacists providing pharmaceutical care for a patient with N-methyl-D-aspartate receptor(NMDAR)encephalitis complicating with multiple organ infections. METHODS:Taking one clinical case as breakthrough point,the points of pharmaceutical care provided by clinical pharmacists for NMDAR encephalitis complicat-ing with multiple organ infections were analyzed,so as to put forward the suggestions in the field of antibiotics selection,medica-tion approach based on pharmacokinetics,ADR disposal and nutrition support. RESULTS:Clinical pharmacists applied pharmaceuti-cal care to resolve ADR as abnormal liver enzyme timely,and the symptom had been improved gradually. Then the patient was dis-charged from the hospital. CONCLUSIONS:Clinical pharmacists provide pharmaceutical care and screen the possible risk of drug use to avoid the occurrence of severe ADR.

Objective To assess the effectiveness of western routine treatments combined with Tongxinluo capsule for angina pectoris .Methods The randomized controlled trials(RCTs ) of western routine treatments combined with tongxinluo capsule for angina pectoris were collected through searching on computer from the following databases ,CNKI (2000 -2011 ) ,WanFang Data (2000 -2011) ,WeiPu Data(2000-2011) ,PubMed(2000-2011) and manual search relevant journals ,conference papers .Results A total of 11 studies were included and improvement rate of abnormal ECG were estimated in 9 studies and improvement rate of symptoms of angina were estimated in 11 studies .ECG clinical evaluation of the treatment group relative to the control group ,relative risk (RR) value was 1 .40 (95% CI:1 .28‐1 .54) ,P<0 .01 ,symptoms of angina clinical evaluation ,treatment group relative to the control group RR value of 1.25 (95% CI:1 .18‐1 .32) ,P<0 .01 .Only slight gastrointestinal discomfort were found in treatment group .Conclusion Tongxinluo capsule in combination on the basis of conventional western treatment could effectively improve the clinical efficacy and drug safety .
