Objective:To discuss the important role of clinical pharmacists in the prevention of medication errors and rational drug use through medication reconciliation in endocrinology department. Methods: The medication reconciliation was given to the diabetic patients over 70 years old newly admitted in the endocrinology department from January to April 2016, and the consistency and appro-priateness of medication orders were verified and the results were collected and analyzed by the pharmacists. Results: Totally 84 pa-tients were enrolled into the research with the average age of (76. 3 ± 5. 0) and the average number of combined diseases of (3. 5 ± 1. 2). The average medications taken by the patients before the admission were (6. 7 ± 2. 9), and 22. 6% of the patients took tradi-tional Chinese medicines and 4. 76% of the patients took health products. The patients whose medications for 24h needed intervention accounted for 27. 38%, the medications orders needed intervention accounted for 3. 67%, and the intervention success rate of clinical pharmacist was 100%. Conclusion:To the patients over 70 years old with type 2 diabetes and multiple diseases treated with a variety of medications, medication reconciliation in 24 hours can effectively prevent the medication errors and promote the rational drug use.

Objective To explore the clinical characteristics and treatment of methylmalonic acidemia(MMA) in order to improve our understanding of it.Methods We analyzed the clinical manifestations,laboratory examinations and treatments of 26 cases of methylmalonic acidemia in children.Results Twenty-four cases were involved in nervous system.Nine patients were involved in renal system.Eight cases of hematological involved.Liver enzyme elevated in 2 cases as well as the cardiac system were involved in 3 cases.One case was with pneumonia onset.The laboratory findings showed metabolic acidosis in 12 cases,hyperhomocysteinemia in 8 cases and remarkable elevation of urinary methylmalonic acid concentration in all cases.Some abnormalities in globus pallidus and cerebral white matter as well as diffuse cerebral atrophy were noted by the brain CT and MRI in 15 cases.Sixteen children have received therapy of vitamin B12,and supplementation of L-carnitine with restricted-protein diet.The follow-up for a period ranging from 3 months to 1.5 years( mean 8.5 months) of 15 cases with medical therapy showed a favorable outcome of nervous system improvement in 12 cases,however,2 patients died from severe metabolic acidosis.8 patients with renal involvement were normal in urine routine and renal function.Conclusion Methylmalonic acidemia has different clinical features,so early urine organic acids analysis by GC/MS method is essential Long-term and reasonable treatment after diagnosis is an effective way to improve the prognosis.

Objective To investigate the effect of recombinant human erythropoietin (rhEPO) on the expression of glutamine synthetase (GS) of cultured rat retinal Müller cells in high glucose environment in vitro.Methods Mtüller cells were isolated from retinas of 10 Sprague-Dawley rats at postnatal day three to five by trypsin digestion,and were randomly divided into six groups,including normal control group,high glucose group,high glucose +5 U/ml rhEPO group,high glucose+ 10 U/ml rhEPO group,high glucose+ 20 U/ml rhEPO group,high glucose+40 U/ml rhEPO groups.After 48 hours,the apoptosis of retinal Müller cells were assayed by terminal transferase-mediated DNA end labelling assay,and the expression levels of GS protein were detected with semi-quantitative immunocytochemistry.Results Compared with the normal control group,the cell viability and GS protein were reduced while the cell death increased in Müller cells cultured in high glucose,the difference was statistically significant (t =27.4,P ＜ 0.01).Compared with the high glucose group,rhEPO treatment reduced the apoptotic Müller cells (t=857.2,2 374.6,2 473.2,2 537.7; P＜0.01),induced the expression of GS proteins (t=3.2,18.0,22.5,26.4; P＜0.05).Conclusions rhEPO can protect Müller cells from apoptosis under high glucose condition.The mechanism may be related to its function to up-regulate the GS protein expression,promote glutamic acid cycle,and reduce the excitotoxicity effects of high concentration of glutamate.

The treatment methods of nourishing qi and resolving blood stasis is an important way to delay aging. Based on the theory that nourishing qi and resolving blood stasis can delay aging, many scholars have conducted lots of clinical and experimental researches nowadays. This article mainly analyzeds the theory and origin of nourishing qi and resolving blood stasis delaying aging, the current situation of clinical and experimentai researches on age-related diseases. The purpose of this article is providing a basis for anti-aging researches on Chinese herbal medicines that have the efficienoy of nourishing qi and resolving blood stasis, and further revealing aging mechanism.

Objective To observe the effects of irbesartan and amlodipine on insulin sensitivity in obese hypertensive patients. Methods 157 moderate hypertensive patients were divided into two greups,which received irbesartan or amlodipine for 16 weeks. The changes of blood pressure,heart rate and weight were observed. Insulin re-sistance was computed using the homeostasis model assessment (HOMA-IR). Results There was no difference in antihypertensive efficacy between the two groups(P>0.05). After 16 weeks of treatment ,the insulin resistance index decreased by 8.7±2.4 vs 6.1±2.6 (P<0.01) and body mass index decreased(28.1±3.8) kg/m2 vs (27.2± 3.2 ) kg/m2 (P<0.05 ) and mean heart rate raised by (73.1 ±10.0 ) kg/m2 vs ( 79.1±11.4) kg/m2 ( P < 0.01 ) in irbesartan group while no such changes were found in amlodipine treated group. Conclusions In obese hypertensive patients,irbsartan and amlodipine exert similar antihypertensive effect, but irbesartan may help to improve some obe-sity-related metabolize disorder,so the obese hypertensive patients may benefit more from irbsartan than from amlo-dipine.

Objective: To investigate the effects of Radix Ginseng and Radix Notoginseng formula on expressions of vascular endothelial growth factor receptor-2 (VEGFR-2) and hypoxia-inducible factor-1alpha (HIF-1alpha) in ischemic myocardium of rats with acute myocardial infarction. Methods: A total of 100 Wistar rats were randomly divided into normal control group, sham-operated group, untreated group, metoprolol (Betaloc) group, and high- and low-dose Radix Ginseng and Radix Notoginseng formula groups. Acute myocardial infarction was induced in the untreated group, Betaloc group, and high- and low-dose Radix Ginseng and Radix Notoginseng formula groups by left anterior descending coronary artery ligation. After 12-day treatment, microvessel density (MVD) in ischemic myocardium was detected by immunohistochemical method, while expressions of VEGFR-2 and HIF-1alpha proteins were detected by Western blotting, and expressions of VEGFR-2 and HIF-1alpha mRNAs were detected by real-time fluorescent quantitative polymerase chain reaction. Results: MVD in the untreated group was increased significantly, higher than those in the normal control group and the sham-operated group (P<0.05) and lower than those in the high- and low-dose Radix Ginseng and Radix Notoginseng formula groups and Betaloc group (P<0.01). VEGFR-2 and HIF-1alpha protein and mRNA expressions in the untreated group were higher than those in the normal control group and the sham-operated group (P<0.05). VEGFR-2 and HIF-1alpha protein and mRNA expressions in the high- and low-dose Radix Ginseng and Radix Notoginseng formula groups and Betaloc group were higher than those in the untreated group (P<0.05). There was a significant difference between the high- and low-dose Radix Ginseng and Radix Notoginseng formula groups (P<0.05). Conclusion: Radix Ginseng and Radix Notoginseng extract can up-regulate the protein and mRNA expressions of VEGFR-2 and HIF-1alpha and increase MVD in ischemic myocardium to improve myocardial ischemia so as to promote the development of collateral circulation.
