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.

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.

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.

OBJECTIVETo search for the best acupuncture and moxibustion treatment program for stroke.
METHODSOne hundred and eighty-three cases of stroke were divided into a scalp-body acupuncture group of 62 cases, a scalp acupuncture group of 60 cases and a body acupuncture group of 61 cases. They were treated for 2 months and then their therapeutic effects were compared.
RESULTSIn the scalp-body acupuncture group, 13 cases were basically cured, 32 cases improved obviously, 15 cases improved, 2 cases was ineffective, and corresponding figures in the scalp acupuncture group were 8, 21, 24, 7, and in the body acupuncture group were 11, 28, 19, 3, with a significant difference between the scalp-body acupuncture group and the scalp acupuncture group (P<0.05) , and with no significant differences between the scalp-body acupuncture group and body acupuncture group, and between the body acupuncture group and the scalp acupuncture group.
CONCLUSIONScalp acupuncture combined with body acupuncture has a better clinical therapeutic effect than that of simple scalp acupuncture for the patient of stroke.

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.

Objective To study MRI findings of pancreatic ducts of piglets with chronic pancreatitis (CP) induced by pancreatic duct ligation and analyze the relationship between pancreatic duct changes in piglets with CP and the pathological severity of CP. Methods Thirty healthy piglets were included in this study. Five piglets were randomly selected as normal control group, and the remaining 25 piglets were served as the experimental group. The duct ligation operations were performed on experimental group. After 2 to 18 weeks, pancreas and pancreatic ducts were observed on MRI. Then the pancreas was removed and graded into three types by histopathology. The relationship between the diameter of pancreatic duct or the pancreatic branch displaying rate and the severity of CP was analyzed by Spearman correlation coefficient. Results CP was found in 21 piglets( 84. 0% ) in the experimental group including mild ( n = 7 ), moderate ( n = 8 ) and severe( n = 6) pancreatitis. Pancreatic ducts were shown in mild CP and the edge of pancreatic ducts was irregular in three cases. The dilated RPD, LPD and MPD constituted the "person" form in moderate and severe CP. The diameter of pancreatic ducts was(0. 9 ±0. 3)mm, (2. 9 ± 1.4)mm and (4. 8 ± 1.2)mm in mild, moderate, and severe CP respectively. The expansion extent of pancreatic ducts was correlated with the severity of CP of piglets (r = 0. 837, P < 0. 05). The pancreatic branch displaying rate increased with the increase of the severity of CP ( r = 0. 990, P < 0. 05 ); the displaying rate was 0/7 for mild, 3/8 for moderate, and 5/6 for severe CP. Conclusions The dilated pancreatic ducts with "person" form in piglets with obstructive CP created by pancreatic duct ligation. The pancreatic duct changes on MRI reflect the severity of CP of piglets.
