Objective To understand and illuminate the bionomic characteristics of prostate specific membrane antigen (PSMA) and splicing variant PSMA5, through detecting the DNA levels of them in different tumor cell strains and prostate tissues. Methods The fluorescent quantization reverse transcriptase PCR (FQ-RT-PCR) method built up by our research group was used to detect the PSMA and variant PSMA5 DNA levels in different tumor cell strains and prostate tissues. Results The PSMA and PSMA5 DNA levels in tumor cell strains and pathological prostatic tissues were obviously more than those of the normal prostatic tissues (F=3.40, 11.94, both P＜0.05), and the PSMA5 DNA level was much higher than was the PSMA DNA level in prostatic carcinoma tissues (P＜0.05). Conclusions The different expressions between PSMA and PSMA5 in different tumor cells and prostatic tissues show that PSMA5 is more specific than PSMA as a prostate carcinoma tumor marker.

OBJECTIVE:To provide the new idea for clinical pharmacists providing pharmaceutical care in oncology depart-ment. METHODS:Applying the principles and methods of clinical pathway,the pharmaceutical care of anti-tumor drugs could be divided into before medication,during medication,after medication and patient education,according to the sequence of taking med-icine. On the basis of evidence-based medicine,the care contents of each unit were established,and the pharmaceutical care path-way (PCP) was formed. During chemotherapy duration for a breast cancer metastasis patient with liver function injury,clinical pharmacists conducted pharmaceutical care for drug pretreatment,ADR monitoring and disposal,patient education,as well as put forward the proposal of drug treatment as supplementing calcium,adjusting the dose of epirubicin and paclitaxel targeting on PCP of zoledronic acid,epirubicin and paclitaxel. RESULTS:Physicians adopted the pharmacist’s recommendations. The patient suf-fered from joint and muscle pain during chemotherapy,and the symptom was relieved after symptomatic treatment by celecoxib;chest and back discomfort was relieved significantly after chemotherapy,and the disease condition kept stable. The patient was dis-charged from the hospital. CONCLUSIONS:PCP focus on the time,content and countermeasures of pharmaceutical care,the pro-gram and treatment results of pharmaceutical care,and promote standardization,formalization,simplification and procedure of pharmaceutical care. Clinical pharmacists conduct individualized pharmaceutical care rapidly targeting on PCP so as to deepen the communication of clinical pharmacists with physicians,nurses and patients,and promote the development of pharmaceutical care smoothly.

Objective To explore the correlation of the TIAM2 functional gene mutations with the bleeding events in patients with coronary heart disease who undergone PCI and postoperative taken anti-platelet drug clopi-dogrel. Methods One hundred and twenty Chinese Han patients who had undergone PCI and postoperative taken anti-platelet drug clopidogrel were orderly enrolled from Guangdong General Hospital. Followed for 6 months after PCI, PCR sequencing was applied to test TIAM2 promoter region genotyping assay. Results After follow-up six months , 113 cases were remained lost of 7 cases , , including 19 cases with bleeding and 94 cases without bleed-ing; Bleeding risk in patients with diabetes mellitus (OR=3.115) or taking statins (OR=11.539), may be high, but there was no significant difference (P > 0.05); TIAM2 promoter region had three variants (c.3168+3116C>T, c.3168+3261A>G,c.3168+3596A>C), including wild-type, heterozygous, and homozygous. The probability of pa-tients with bleeding were 36.84%, 52.63%and 10.53%, and there is a certain chain of state , but the genotype was not significantly correlated with bleeding events of clopidogrel antiplatelet therapy (P>0.05). Conclusion Clopi-dogrel antiplatelet therapy bleeding events were not significantly correlated with TIAM2 functional gene mutation.
