OBJECTIVE:To provide reference for standardizing chemotherapy drug use in tumor patients,and to investigate the points of pharmaceutical care. METHODS:2 242 medical records of tumor chemotherapy were sampled from 4 third grade class A hospitals to investigate chemotherapy drug plan and pharmaceutical care. The reasons for irrational drug use were analyzed, and the points of pharmaceutical care were summarized. RESULTS:There were 1 295 cases of irrational chemotherapy drug use, among which irrational dose accounted for 26.87%;irrational antiemetic drugs use 14.44%;irrational chemotherapy plan 13.13%;irrational drug selection 10.89%;irrational dosing order 10.04%. 6 items of rational chemotherapy drug use monitoring index were summarized,which were rationality of scheme selection,drug selection,drug dose,dosing time and order,solvent concentration, route of administration,adjuvant drug use;covering the process of chemotherapy. CONCLUSIONS:Pharmaceutical care can be standardized through rationality investigation on chemotherapy drug use of tumor patients,which contributes to improving pharma-ceutical care level of clinical pharmacists,and rational drug use the clinic.

OBJECTIVETo investigate the progressive motility, (PR), total motility (progressive + non-progressive motility, PR + NP), and acrosin activity of sperm from normal and infertile men at different time points after sperm activation.

METHODSBased on the 5th edition of the WHO Laboratory Manual for the Examination and Processing of Human Semen and the results of modified Papanicolaou staining, we divided the semen samples into groups A (normal, n = 28), B (oligoasthenoteratospermia, n = 30), and C (asthenoteratospermia, n = 32). At 1, 24, and 48 hours after sperm activation, we detected sperm PR and PR + NP by CASA and chemical colorimetry, and determined sperm acrosin activity using the modified Kennedy method.

RESULTSSperm PR and PR + NP were significantly decreased in all the three groups at 1-24 hours and even more significantly at 24-48 hours after sperm activation as compared with the baseline (P < 0.05). Sperm acrosin activity showed remarkable reduction in group A (P = 0. 013) , even more significant at 1-24 hours than at 24-48 hours after sperm activation, but not in groups B and C (P = 0.519 and 0.979).

CONCLUSIONSperm PR, PR + NP, and acrosin activity are all decreased with the extension of time after sperm activation, each in a specific manner. Examination of sperm acrosin activity should be applied as a routine tool in the assessment of male fertility.

To improve bond selectivity of recombinant β-glucuronidase in Escherichia coli (PGUS-E), based on the PGUS-E structure guidance, three key points R329, T369 and N467 were identified to be responsible for the bond selectivity of PGUS-E, and further saturation mutagenesis was conducted. Two positive mutants R329K and T369V were obtained by a combined selection technique of thin-layer chromatography and high performance liquid chromatography. Compared to PGUS-E, the bond selectivity of mutants R329K and T369V increased by 26.9% and 34.3%, respectively; whereas the biochemical properties such as pH and temperature profile were unchanged. Nevertheless, the activity was decreased compared to PGUS-E. These results further confirmed that sites R329 and T369 played important roles for the bond selectivity and activity. In summary, this study significantly increased the bond selectivity of PGUS-E by structure guided saturation mutagenesis, providing experimental support for elucidating the relationship between the structure and function of PGUS-E.

Conclusion: VEGF165 and HGF could improve myocardial perfusion and function in experimental porcine after MI, VEGF165 and HGF promote cardiomyocyte proliferation via different pathways.

Objective To observe the MRI findings of normal pancreas in piglets. Methods Eight healthy piglets underwent MR examination, and the morphology, size, signal intensity of pancreas were observed. After MR imaging, all piglets were abdominally incised to observe the anatomy of pancreas and pancreatic adjacent structures. The opening of both common bile duct and pancreatic duct were detected during operation. Two piglets were sacrificed after operation and the whole pancreases were dissected for anatomic research. Results The pancreas of piglets was composed of three parts: right lobe, median lobe and left lobe. All the lobes were displayed clearly on MRI. The signal intensity of pancreas was higher than that of liver and spleen on T1WI, whereas lower than that of liver and spleen on T2WI. On MRCP, pancreatic duct was not presented, whereas the common bile duct could be seen clearly. The opening of common bile duct located at superior part of duodenum (nearby the pylorus) and the opening of pancreatic duct situated at duodenal papilla corresponding to pancreatic right lobe. Conclusion MRI can show the pancreas of piglets very well. The morphology of pancreas and features of common bile duct conjunction with pancreatic duct in piglet are different from those in human.
