Background The circulating endothelial progenitor cells (EPCs)play an important role in postnatal vasculogenesis and restoration of endothelial injury.Previous investigation illustrated that a reduced ocular blood flow and vascular dysfunction caused by endothelial dysfunction plays a role in the pathogenesis of glaucoma.However,endothelial system accommodation is accomplished with the circulating EPCs.Objective The present trail was to investigate EPCs change in patients with primary acute angle-closure glaucoma (PACG)and explore the role of EPCs in the pathogenesis of PACG. MethodsA prospective cohort study was designed.Thirty patients with PACG were enrolled in Tianjin Medical University General Hospital as PACG group,and 20 normal subjects served as control group.Periphery bloodsamples were obtained fromall the patients and thenstained with saturating concentrations of monoclonal antibodies,FITC-conjugated anti-CD34 and CD133 mAb.EPCs identified by CD34,CD133 were enumerated by flow cytometry,and the correlation between EPCs change and its relative factors was analyzed.Informed consent was obtained from each subject before any medical procedure. Results No significant differences were found in age,gender,vascular-related risk factor,blood biochemical indicators between PACG group and normal contol group(P＞0.05 ),but a higher intraocular pressure( IOP)was displayed in PACG group compared with normal control group ( P =0.00 ).The numbers of EPCs were ( 48 ± 22 ) cells/ml in PACG group and ( 65 ± 20 )cells/ml in normal control group with a significant difference between them (P=0.004).In PACG group,the numbers of EPCs were(60± 19 )cells/ml and (34 ±7 )cells/ml respeetively in phase 1 and phase 3 of optical nerve damage (Z=-3.015,P=0.002 ).There was a negative correlation between EPCs numbers and baseline IOP within a certain range( r=-0.835,P＜0.05 ).However,no obvious correlations were seen between EPCs numbers and blood lipid Level,blood glucose level or glaucoma course ( r =0.343,P =0.227 ; r =-0.203,P =0.419 ; r =0.198,P =0.610 ).The EPCs numbers in PACG patients with cardiovascular disease were(56±22)cells/ml and that of without PACG were (35± 15 ) cells/ml( P =0.005 ). ConclusionsThe numbers of EPCs decrease in PACG patient.These results imply that EPCs might play role during the restore of the optical nerve damage in PACG eye.

OBJECTIVE: To provide references for the application of automatic oral drug dispensing system in hospital pharmacy. METHODS: The chief structure of automatic oral drug dispensing system in our hospital (TR-200FDS system) was introduced; the main working process and employment of this system were briefly introduced,and its advantages and disadvantages were discussed. RESULTS: The application of automatic oral drug dispensing system is characterized by convenience,cleanness,quickness and accuracy,but the relative costs are on the high side. CONCLUSION: The application of automatic oral drug dispensing system in hospital pharmacy can enhance hospital pharmaceutical care level,and it may represent the trend of the development in hospital pharmacy.

The effects of pretreatment methods of Jerusalem artichoke tubers on microbial lipids fermentation with an oleaginous yeast strain Rhodosporidium toruloides Y4 were investigated in shaking flask culture.The yeast strain accumulated substantial amount of lipids using either purple-or white-skinned Jerusalem artichoke tubers as sole carbon and energy source.When cells were cultured on the extracted juice or the acidhydrolysate,cellular lipid content reached 40%(w/w),while cultured on the pulp,the white-skinned tubershadhigher lipid productivity,yielding 12.1 g lipids per100 g dried tubers.Major fatty acid constituents of microbial lipids were those contained 16-and 18-carbon atoms based on GC analysis,which is quite similar to traditional vegetable oil.Microbial lipids prepared from Jerusalem artichoke can be applied to biodiesel production.

In this research,we chiefly explored a new fast test method--microtox technology to evaluate the comprehensive toxicity of Shen Mai injection.We investigated characteristic parameters of vibrio fischeri (CS234) under different conditions in the pursuit of the optimum test parameters of the reliable method;and then locked the best parameters for Shen Mai injection assay with the products from different manufacturers by microtox fast test.As a result,the optimum reaction condition included 0.9 mL recovery liquid in each freeze-dried vial and 50 μL bacteria suspension of each sample within 2 mL solution in aggregate with 10-mins detection after adding bacteria suspension which pH value ranging from 5 to 10 and luminous intensity from 0.8 to 1.2 million in 10 mins.The relative standard deviation values of replication experiment and precision test were all below 15％.Under this optimum detection condition,it was found that the EC50 values were 35.60％,92.34％ and 146.57％,differing among the samples from three representative drug manufacturers,respectively (P ＜ 0.01).In conclusion,the concentration-effect relationship of Shen Mai injection existed in the toxicity assessment of vibrio fischeri with various ECs0 values from the three manufacturers.These results suggested that biological detection standards of Shen Mai injection presented great growth potential.Microtox-based fast test in the evaluation of comprehensive toxicity of ShenMai injection showed favorable application prospects over controlling the quality of different sources of products.

OBJECTIVEObserve and analyze the informations of western medicine and traditional Chinese medicine in patients with coronary heart disease (CHD), in order to provide reference for clinical treatment.

METHODSelect patients with CHD in diagnosis of the first place in 17 hospitals, drug informations of these patients were analyzed using frequency method and association rules.

RESULTIn 84 697 patients,there were 47 564 males and 32 882 females. The median age was 71 years old, 76 172 patients have medicine records, including 278 kinds of western medicine and 331 kinds of traditional Chinese medicine. Aspirin was the most common used western medicine (51 132 patients, 67.08%), followed by isosorbide dinitrate, clopidogrel etc. The most common used traditional Chinese medicine was danhong injection, followed by shuxuetong injection. After classified the drugs, at the forefront of western medicine were antiplatelet drugs, nitrates drugs, statins, beta blockers, calcium antagonists, ACEI; the most used in traditional Chinese medicine was injection of blood-activating and stasis-resolving, followed by oral preparations of blood-activating and stasis-resolving medicine, Fuzheng class oral medicine, purgation medicine etc. After association rules, combination therapy among western medicine was the most common, combination of western medicine with blood-activating and stasis-resolving was very commonly, especially antiplatelet drugs and nitrates drugs.

CONCLUSIONWestern medicine in the treatment of patients with CHD was in accordance with the guidelines recommend, but with the lower utilization rate. Traditional Chinese medicine has become an important method for the treatment of CHD, promoting blood circulation and removing blood stasis is an important part of traditional Chinese medicine treatment in patients with CHD.
