Objective:To investigate the breakthrough points and methods of pharmaceutical care performed by clinical pharma-cists for chemotherapy-induced Ⅳ degree myelosuppression. Methods: One advanced lung adenocarcinoma patient suffering from IV degree myolosuppression after being treated with pemetrexed combined with nedaplatin was selected as the example, and the chemother-apy regimen, the cause and treatment of IV degree myolosuppression and the pharmaceutical service could be carried out were ana-lyzed. Results: With the help of clinical pharmacists, the patient conquered chemotherapy-induced myelosuppression, and clinical pharmacists enhanced the awareness of pharmaceutical care and played a positive role in the safe and effective drug use. Conclusion:The participation of clinical pharmacists in clinical pharmaceutical care through providing pharmaceutical service is beneficial to safer and more effective drug therapy.

BACKGROUND:Non-heart beating donors have become the most promising source of donor in recent years. Tofurther improve donor preservation solution, on the basis of conventional storage solution hypertonic citrate adenine solution, artificial cordyceps was added to prepare artificial cordyceps compound solution. It is hoped to reduce donor injury and to elevate donor quality by antioxidation. OBJECTIVE: To investigate the preservation effect of artificial cordyceps compound solution on isolated renal from non-heart-beating rats. METHODS: Medulas of 39 Sprague-Dawley rats were injured. Withoutin vitro respiratory and circulatory supports, non-heart-beating models were established and randomly divided into three groups: artificial cordyceps compound group (n=15), hypertonic citrate adenine solution group (n=15) and physiological saline group (n=9). The kidneys of rats in different groups were stored in artificial cordyceps compound solution, hypertonic citrate adenine solution and physiological saline at 4℃. RESULTS AND CONCLUSION: Compared with the hypertonic citrate adenine solution group, after 6 and 12 hours of preservation, morphological injury was mild, apoptotic index, malondialdehyde, Bax and Caspase-3 expression levels decreased, superoxide dismutase activity and Bcl-2 expression increased; after 24 hours, the degree of injury was similar, malondialdehyde content decreased, and superoxide dismutase activity increased in the artificial cordyceps compound group. These findings indicated that the preservation effect of artificial cordyceps compound on antioxidation and inhibition of apoptosis was better than that of hypertonic citrate adenine solution in non-hearting beating rats.

OBJECTIVETo explore the effect of curcumin on TGF-β2 regulated peroxisome proliferater activated receptor y (PPAR-γ)/platelet derived growth factor β (PDGF-β) signaling pathway in lung fibroblasts of mice.

METHODSC57BL/6 mouse lung fibroblasts were in vitro cultured with TGF-β2, curcumin, or TGF-β2 plus curcumin. The cell proliferation was detected by cell growth counting in the blank control group, low, middle, and high dose curcumin groups (5, 25, 50 μmol/L), the TGF-β2 (10 ng/mL) group, TGF-β2 (10 ng/mL) plus curcumin (5, 25, 50 μmol/L) groups. mRNA expressions of PPAR-γ, platelet-derived growth factor receptor β (PDGFR-β), fibroblast growth factor R1 (FGFR1) were detected using reverse transcription PCR. Protein levels of PPAR-γ and collagen-1 were detected using Western blot and ELISA in the blank control group, the TGF-β2 group, the TGF-β2 (10 ng/mL) plus curcumin 50 μmol/L group.

RESULTSCompared with the blank control group, curcumin 50 μmol/L showed the most significant inhibition on cell proliferation at 48 h and 72 h. Compared with the TGF-β2 group, TGF-β2 (10 ng/mL) plus curcumin 50 mol/L also showed the most significant inhibition on cell proliferation at 48 h and 72 h. Compared with the blank control group, mRNA expressions of PPAR-γ and PDGF-β, as well as protein expression of PPAR-γ increased, the collagen-1 expression also increased in the TGF-β2 group (P < 0.05). Compared with the TGF-β2 group, mRNA expressions of PPAR-γ obviously increased in the TGF-β2 (10 ng/mL) plus curcumin 25 μmol/L group and the TGF-β2 (10 ng/mL) plus curcumin 50 μmol/L group, higher than that in the TGF-β2 (10 ng/mL) plus curcumin 5 [μmol/L group (P < 0.05). mRNA expressions of PPAR-γ was higher in the TGF-β2 (10 ng/mL) plus curcumin 50 μmol/L group than in the TGF-β2 (10 ng/mL) plus curcumin 25 μmol/L group (P < 0.05). mRNA expressions of PDGF-β was lower in TGF-β2 (10 ng/mL) plus curcumin groups than in the TGF-β2 group (P < 0.05). Besides, PDGF-β mRNA expressions were lower in the TGF-β2 (10 ng/mL) plus curcumin 50 μmol/L group than in the TGF-β2 (10 ng/mL) plus curcumin 5 μmol/L group and the TGF-β2 (10 ng/mL) plus curcumin 25 μmol/L group (P < 0.05). There was no statistical difference in FGFR1 mRNA expressions between the TGF-β2 group and 3 TGF-β2 plus curcumin groups (P > 0.05). Compared with the TGF-β2 group, PPAR-γ protein expressions increased and collagen-1 protein expressions decreased in the TGF-β2 (10 ng/mL) plus curcumin 50 μLmol/L group (P < 0.05, P < 0.01).

CONCLUSIONSCurcumin not only could inhibit TGF-β2 induced proliferation of lung fibroblasts, but also could inhibit the synthesis of collagens. These might be associated with up-regulating PPAR-γ expressions and down-regulating PDGF-β expressions. Therefore, curcumin might inhibit the occurrence and developing of lung fibrosis through blocking PPAR-γ/PDGF-β signaling pathway.

OBJECTIVETo optimize the method in the Chinese Pharmacopoeia for determining Salviae Miltiorrhizae Radix et Rhizoma.

METHODTanshinone II(A) and salvianolic acid B were selected as the index in optimization of the sample preparation method of Salviae Miltiorrhizae Radix et Rhizoma in Chinese Pharmacopoeia. Orthogonal test was used to optimize the extraction process of Salviae Miltiorrhizae Radix et Rhizoma, and concentration of contents were detected by high performance liquid chromatography method. A detection of using methanol-water (85: 15) at wavelength of 270 nm was employed for tanshinone II(A) and a detection of using methanol-acetonitrile-formic acid-water (30:10:1: 59) at wavelength of 286 nm was employed for salvianolic acid B.

RESULTThe optimized extraction process of tanshinone II(A) and salvianolic acid B was: extracted by 90% methanol and reflux twice (0.5 h each time) at 75 degrees C, extracted by 70% methanol and reflux twice (1.5 h each time) at 75 degrees C, respectively.

CONCLUSIONOptimized extraction and determination methods could be used to reflect the content of tanshinone II(A) and salvianolic acid B in Salviae Miltiorrhizae Radix et Rhizoma more accurately and efficiently.

Phytoestrogens are bioactive substances existing in natural plants. They have similar molecular structure to those of estrogens. In this article we introduced their classification and sources, and elucidated their effects on heart from aspects involving cardiac function and myocardial electrophysiology. By regulating serum lipid metabolism, arterial vessels, cytokine levels, and coagulation/fibrinolysis system, phytoestrogens possess the effects of anti-atherosclerosis and may be used to prevent and treat cardiovascular diseases.
