ABSTRACT
OBJECTIVE To explore the effects of narrative pharmacy management on medication compliance， negative emotions， and quality of life in patients with cardiovascular disease complicated with negative emotions. METHODS A total of 49 patients with drug use problems and negative emotions attending the cardiovascular pharmacy clinic of Wuhan First Hospital from February to August 2023 were selected as the study objects， narrative pharmacy model was applied for patient management during their visits； pharmaceutical care and emotional management were performed after 2 weeks of treatment and a follow-up visit was conducted to evaluate and record the management effect one month later. RESULTS Adopting a narrative pharmacy management model， 49 patients were involved in 114 drug related consultation questions. Compared with the visit， after one month of management， the number of medication types taken by patients significantly decreased [4.00 （2.00， 6.00） vs. 3.00 （1.50， 5.00）， P＜0.05]， the incidence of adverse reactions significantly decreased （32.65% vs. 2.04%， P＜0.001）， the rate of blood pressure and lipid compliance significantly increased （30.61% vs. 95.92%， P＜0.001）， and the score of the patient’s medication compliance significantly improved （[ 3.94±2.44） vs. （6.78±2.07）， P＜0.01]. The depression score significantly decreased [3.00 （2.00， 4.50） vs. 2.00 （0.00， 3.00）， P＜0.001]， the anxiety score significantly reduced [3.00 （2.00， 4.50） vs. 1.00 （0.00， 2.00）， P＜0.001]， quality of life score was significantly improved [22.00 （19.00， 22.00） vs. 23.00 （23.00， 24.50）， P＜0.01]. In the satisfaction survey， there was a slight increase in the overall satisfaction proportion （91.84% vs. 97.96%， P＞0.05）. CONCLUSIONS The application of narrative pharmacy in cardiovascular pharmacy clinic can improve patient compliance， reduce adverse drug reactions， enhance the effectiveness of drug treatment， avoid drug interactions， effectively improve the anxiety and depression， and ultimately improve the quality of life.
ABSTRACT
Objective To synthesize 18F labeled N-(2-18 F-fluoropropionyl)-L-glutamine (18 F-FPGLN) for tumor PET imaging,and to perform its biodistribution study on normal mice and PC-3 tumorbearing nude mice.Methods 4-nitrophenyl-2-18F-fluoropropionate (18F-NFP) was synthesized on the MF2V-IT-I synthesizer and was purified by semi-preparative HPLC.Anhydrous 18F-NFP was added to a solution of L-glutanine t-butyl ester to synthesize 18F-FPGLN t-butyl ester,which was hydrolyzed by HCl (3 mol/L) and neutralized with NaOH (2 mol/L) solution.18F-FPGLN product was collected for further study.Biodistribution study was performed on normal Kunming mice and PC-3 prostate cancer tumor-bearing nude mice,respectively.Results 18F-FPGLN was synthesized with 10％-15％ (decay uncorrected) overall radiochemical yield after 130 min of radiosynthesis.The radiochemical purity was higher than 96％.Rapid and high uptake of radiotracer was observed within the kidneys,and was quickly excreted through the urinary bladder.The uptake in kidney reached (35.0±1.2) ％ID/g at 5 min post-injection,and descended to (1.5±0.3) ％ID/g at 120 min.The liver,lung,heart and small intestine showed relatively moderate uptake of radioactivity.The uptake in the pancreas,muscle,spleen,stomach and brain was low,and the lowest uptake of (1.5±0.3) ％ID/g was found in the brain at 30 min post injection.High accumulation of 18F-FPGLN in PC-3 xenograft was observed,and the tumor/muscle ratio reached 2.07 at 60 min post injection.Conclusion A novel N-position 18F-labeled glutamine analogs 18F-FPGLN,with favorable pharmacokinetic characteristics,is synthesized successfully,which makes it possible to perform tumor PET imaging using 18F-FPGLN subsequently.
ABSTRACT
Aim To determine the effective compo-nents of Semen Ziziphi Spinosae for sedative-hypnotic and its mechanism. Methods The extraction of Se-men Ziziphi Spinosae and the rat brain homogenates were prepared. High concentrations of Diazepam com-petitively replaced the ligand compounds of Semen Ziz-iphi Spinosae combining BDZ receptor in brain tissue, and all the compounds with sedative and hypnotic effects were collected and identified by HPLC and LC-MS technique, as the compounds extracted from the brain tissue were administered with Semen Ziziphi Spi-nosae. The brain tissue was administered with Diaze-pam, and with Semen Ziziphi Spinosae and Diazepam. Results The HPLC chromatograms show that the peak time of BDZ receptor ligand compounds was 2. 71 min and 46. 87min, when compared with Diazepam. And the LC-MS chromatograms display the relative molecu-lar weight of the ligand compounds was 274. 28 m/z, 453. 34 m/z,496. 34 m/z and 608. 38 m/z respective-ly. According to the fingerprint of Semen Ziziphi Spi-nosae, these compounds may be fatty acid substances and lupine pill triterpene compounds. Conclusions On the basis of the principle of receptor ligand bind-ing, we established a way to quickly analyze and iden-tify the role of natural products in the same drug target compounds. The method not only can clearly define the effective components of natural products, but also clar-ify the mechanism of action of the compounds. The ac-tive ingredient of calm hypnosis in Semen Ziziphi Spi-nosae may be fatty acid substances Palmitic acid ( C16 H32 O2 ) and lupine pill triterpene compounds Alphitolic acid( C30 H48 O4 ) and Spinosin( C28 H32 O15 ) . They exert their sedative and hypnotic effects by combining with BDZ receptor, and the research has laid a theoretical foundation for the further study about mechanism of Se-men Ziziphi Spinosae.
