Alpha-fetoprotein (AFP) was first discovered over 50 years ago, and is currently applied clinically in diagnosis, effects evaluation and relapse judgement of tumors especially for the primary hepatocellular carcinomas.And as an effective tumor marker, AFP test has become one of the essential items in physical examination.However, its clinical application is not limited to primary hepatocellular carcinomas,and its great application value has been proved in many benign diseases and other tumors (non-hepatic carcinomas).

Objective To summarize the experience in nursing 2 patients with anti-glomerular basement membrane disease.Method The nursing measures such as close observation of disease condition,careful nursing of medication,nursing during the treatment of double filtrated plasmapheresis and mental care to the patients and their family members.Results After treatment,the concentration of anti-GBM antibody was declined and the level of serum creatinine was also decreased.The renal function got rccovered to a certain extent.Conclusion Such nursing points as close observation of renal and pulmonary pathgenesis,timely and accurate administration of medicine according to doctor's orders and active observation and prevention of complication from double filtrated plasmapheresis are key.

Atherosclerosis,as a chronic inflammatory vascular disease,involves many cellular and molecular events in its formation and progression from an early fatty streak lesion to a highly dangerous rupture-prone plaque.The vulnerability or destabilization of atherosclerotic plaques is closely associated with plaque composition.Such imaging modality as magnetic resonance imaging(MRI),which allows of the evaluation of the plaque composition at the cellular and molecular level,may differentiate vulnerable and destabilized plaques and monitor the efficacy of antiatherosclerotic therapies.This paper gives an overview of molecular imaging strategies currently used for targeting the inflammation markers of atherosclerotic plaque vulnerability.

Objective To find out about the use of anti-infectious agents by tumor outpatients of the hospital. Methods A survey was conducted on 1 011 prescriptions for anti-infectious agents written out in the hospital from October to December of 2003 and an analysis was made of the structure and rationality of their use by means of drug utilization studies. Results The utilization rate of anti-infectious agents was 8.35% , accounting for 1.09% of the total sum of money for the prescriptions. The kinds of anti-infectious agents used were mostly cephalosporins and quinolones. The utilization rate of agents of compatibility was 4.44%. The drug utilization index of some chemicals was close to 1.00, accounting for about 44.44% . Conclusion There is no widespread abuse of anti-infectious agents by the outpatients of the hospital and the utilization rates of anti-infectious agents and agents of compatibility are low. Still, there are some problems in the use and compatibility of certain agents and the rationality of their use is to be questioned. The use of anti-infectious agents should be planned in a scientific way and in line with the economic condition of the patients.

Phosphorylation of beta-catenin tyrosine residue 654 plays an important role in the epithelial to myofibroblast transition (EMT). Introducing mimic peptide of tyrosine residue 654 domain of beta-catenin into cells may influence phosphorylation of beta-catenin tyrosine residue 654. To deliver this mimic peptide into renal epithelial cells, we used penetratin as a vector, which is a novel cell permeable peptide, to deliver hydrophilic molecules into cells. A tyrosine 654 residue domain mimic peptide of beta-catenin (PM) with fused penetratin was constructed, purified and then detected for the penetration of the mimic peptide into human renal tubular epithelial cells (HK-2). The results showed that purified fusion mimic peptide could efficiently and rapidly translocate into human renal tubular epithelial cells. It is concluded that a cell-permeable peptides mimic of tyrosine residue 654 domain of beta-catenin was successfully obtained, which may provide a useful reagent for interfering the human renal tubular epithelial-mesenchymal transition.

BACKGROUND:It has been proved that Rhizoma Chuanxiong can promote osteoblast proliferation and differentiation.
OBJECTIVE:To further observe the effects of tetramethylpyrazine (Ligustrazine) extracted from Rhizoma Chuanxiong on osteoblast proliferation and type I col agen expression.
METHODS:Mouse osteoblast cel line MC3T3-E1 was cultured in medium containing 1, 5, 10, 15 and 20 mg/L Ligustrazine, respectively. Osteoblast proliferation was detected by cel counting kit-8 assay, and alkaline phosphatase activity and type I col agen level measured using ELISA method.
RESULTS AND CONCLUSION:Different concentrations of Ligustrazine al significantly promoted the osteoblast proliferation and type I col agen level compared with the blank control group (P<0.005). The activity of alkaline phosphatase in al Ligustrazine groups except 15 and 20 mg/L groups was significantly higher than that in the blank control group (P<0.005). These results show that Ligustrazine isolated from Rhizoma Chuanxiong can effectively promote the osteoblast proliferation and type I col agen expression, with the optimum concentration of 10 mg/L.

Objective To assess the clinical use of anti-Parkinson's disease(PD)drugs in the patients with PD,and provide a basis to formulate an effective clinical drug program.Methods 190 PD patients were interviewed by questionnaires about resources,dosage and costs of anti-PD drugs from April,2004 to March,2005.Results By retrospective analysis,number of drugs used in per patient per year was 2.88;levodopa dosage and Levodopa Equivalents(LDE)per patient were 323.0 mg/d and 318.6 mg/d respectively,and LDE increased significantly following by scores of Hoehn-Yahr(H&Y)class increasing(P

0.05).Conclusion:So-fastTM can greatly improve the penetration of PS-ODN into S.mutans and can be used as appropriate delivery system of PS-ODN for S.mutans. No matter what approaches were adopted, the uptake rate reached the maximum at 5 ?mol/L and 2 h-exposure. The penetration can not be enhanced by increasing the PS-ODN concentration and the transformation time.

Objective To find out nutrient support drug utilization in cancer patients in our hospital. Methods An analysis was made by means of drug utilization research into the structure and rationality of nutrient support drug utilization in our hospital through an investigation into the detailed records of the dispensary from 1999 to 2002 and into 1 014 medical records from 2002. Results The variety, quantity, and cost of nutrient support drug utilization in the four years rose respectively by 58.82%, 71.66% and 28.16%. 49.30% of the cancer patients whose medical records were surveyed used such drugs. The quantity and person time ratio of PN and EN drug utilization was respectively 14∶1 and 13∶1, with malnourished patients accounting for 19.80%. Of the PN drugs whose DDD value could be determined, most had a DUI value that was greater than 1 whereas most of the EN drugs had a DUI value which was smaller than 1. Conclusion The variety, quantity, and cost of nutrient support drug utilization in the four years rose rapidly. The quantity and person time of PN drug utilization were much higher than those of EN drug utilization. Doubts could be cast in the handling of indications for nutrient support drug utilization in some patients and the doses of some nutrient support drugs prescribed were not so rational. Further explorations need to be made into the rational application of nutrient support treatment.
