China Pharmacy 2015;(20):2858-2860
OBJECTIVE:To find suitable pharmaceutical care for our hospital. METHODS:The literature research and expert-consultation were adopted to determine the project of pharmaceutical care. Meanwhile,related information were analyzed by the questionnaire survey,statistical analysis interview and other methods in our hospital,such as the content,methods,level and quali-ty of pharmaceutical care. RESULTS:The determined project of the pharmaceutical care and five-point scale were as follows:pre-scription audit 4.53,medication consultation 4.21,prescription analysis 3.56,information about the medication for doctors and nurses 3.73,to establish medical records of hospitalized patients 3.14,ADR monitoring 4.33,drug therapy monitoring 4.31,to par-ticipate in clinical drug therapy 4.03,education about drug use 4.12,to design individualized dosing regimens 3.98,pharmaceutical research 3.58,to popularize pharmaceutical knowledge and education service 4.01. CONCLUSIONS:The hospital should empha-size clincal pharmacist work and software and hardware construction entirely;make the best of modern approach to carry out phar-maceutical care,mainly involving prescription audit and ADR monitoring. However,the problems are that the content of some pharmaceutical cares are not complete,and become a mere formality;clinical pharmacists do not receive systematic trained,the pharmaceutical researches have not been carried out systematically.

China Pharmacy 2007;0(36):-
OBJECTIVE:To establish the quality criteria for Gengnianjingxin capsules.METHODS:The constituents of Fructus Ligustri Lucidi,Radix Polygoni Multiflori,Semen Sesami Nigrum,and Flos Albiziae etc in Gengnianjingxin capsules were identified by TLC; the content of Paeoniflorin in Gengnianjingxin capsules was determined by HPLC. The chromatographic separation was performed on a ODS-(3)C18 column with mobile phase consisted of acetonitrile-phosphate 0.1% (16∶84) at a flow rate of 1.0mL?min-1. The detection wavelength was 230nm. RESULTS:Fructus Ligustri Lucidi,Radix Polygoni Multiflori,Semen Sesami Nigrum,and Flos Albiziae were all well-separated and clear spots were noted in TLC. The calibration curve was linear for Peoniflorin in the range of 0.256 2~1.281 0?g?mL-1(r=0.999 9), with the average recovery rate of 101.86% and RSD of 1.72%(n=5),CONCLUSION:The established criteria are suitable for the quality control of Gengnianjingxin capsules.

China Pharmacy 2001;0(07):-
OBJECTIVE:To extract and analyze the compositions of fatty oil of Semen Pharbtidis METHODS:The fatty oil was extracted with CO2 supercritical fluid The content and compositions were determined by gravimetric analysis and GC-MS respectively RESULTS:The oil content of Semen Pharbtidis was 34 78% Among the fatty acids,linoleic acid,oleic acid and palmitic acid were dominant The unsaturated fatty acids accounted for 88 70% of the total fatty acids,and the major saturated fatty acid was palmitic acid CONCLUSION:The oil of Semen Pharbtidis is of high-quality,and the analysis results provide a scientific basis for exploitation and utilization of the oil of Semen Pharbtidis

The genetic indentification of 16S rDNA or ITS, capability of phosphate-solubilization and pH of medium, and optimization of medium of some microorganism isolated from mangrove were investigated in this study. The result showed that the fungi normally had much higher capacity to dissolve the inorganic phosphate than the bacteria, the capacity of the fungi was closely correlated to the pH of medium, but the relationship was weak for the bacteria. It was illustrated by single factor experiments that the optimal carbon and nitrogen sources were maltose and urea respectively. The orthogonal design was employed in testing the optimum composition of medium composed of 5 g/L maltose, 0.05 g/L urea, 5 g/L NaCl, pH 5. In this optimal medium, the effectively enrichment of bacteria could reach up to 6.06?109 CFU/mL under 30?C for 48 hours cultivation.

BACKGROUND:Stem cel is a kind of pluripotent cels with self-replication ability, which can differentiate into various cels under certain conditions. Furthermore, stem cels are rich in a variety of growth factors, which can induce the generation of vessels and nerves, and improve the blood supply of lower limbs, thereby achieving the treatment and preventions of lower limb ischemia OBJECTIVE:To summarize and compare the recent achievements in the theory and therapeutic efficacy of stem cels from different sources in the treatment of diabetic foot. METHODS:The first and second authors retrieved PubMed, Sciencedirect and Medline databases for relevant articles published from January 2000 to January 2015. The key words were “diabetic foot, pathogenesis, stem cel therapy” in English. Initialy, 186 articles were retrieved, and finaly 44 articles were included in result analysis. RESULTS AND CONCLUSION:Stem cels can be a new choice for the treatment of diabetic foot. After stem cel therapy, corresponding symptoms have been aleviated, including the generation of new blood vessels and the reshaping of the colateral vessels, the improvement of motor nerve conduction velocity and nerve reflex, the improvement of the sense of skin pain and temperature, and pain relief. It is stil unclear whether alogeneic stem cels are safe or not, but autologous stem cels, especialy bone marrow mesenchymal stem cels, can be better able to repair damaged vessels and nerves and restore the microcirculation of blood supply. Currently, we need to do more basic and clinical researches to solve the folowing problems: to confirm the effectiveness and safety of stem cel therapy for diabetic foot; to identify whether there is a difference in the differentiation and secretory activity between stem cels in diabetic patients and ordinary people; to give ful play to the treatment of diabetic foot.
