A recent development of the determination of proteins by some molecular spectral analytical methods such as spectrophotometric method, fluorospectrophotometric mehtod, and resonance Rayleigh scattering methods was reviewed. The important reaction systems and their analytical characteristics are listed in the tables. 97 references are quoted.

Objective To screen and identify protein interacted with enterovirus 71 (EV71)3A protein by means of T7-phage display system.Methods The prokaryotic expression vector of 3A protein was constructed for expressing and purifying 3A pro-tein.With 3A protein as the target protein,the T7-phage display system was adopted to screen the human hepatocyte cDNA library. The screened products were performed the DNA sequence analysis and the homologous research.Results 3A protein was expressed and purified,after 4 rounds of biopanning,37 positive clones were selected.The inserted fragments were amplified by PCR using specific T7 primer.The products were sequenced,2 proteins were identified to interact with 3A protein by homologous analysis. Conclusion Trough the T7 phage display system,two proteins interacted with 3A are obtained.The possible function of 3A protein can be speculated by researching the function of these two proteins,which lays the foundation for the further studying the pathogen-ic mechanism of EV71.

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.

Objective To investigate the expression and significance of DLL4 in endometriosis.Methods 83 cases due to ovarian cyst surgery from December 2010 to September 2013,were selected in the Second Affiliated Hospital of Zhengzhou University,and were randomly divided into two groups in accordance with the random number table.Group A:48 cases were induded after staining from 83 patients who were tahen a part of cyst wall;Group B:of laparoscopic ovarian cyst surgery in 83 patients,37 cases of simultaneously hysteroscopy due to fertility requirements,exclude endometrial lesions,were taken reign uterine endometrium.The American fertility association revised standard (r-AFS)in 1985 was used to divide the clinical stage:Group A:21 cases of Ⅰ ~Ⅱ stage,27 cases of Ⅲ ~Ⅳ;Group B:16 cases of Ⅰ ~Ⅱ stage,21 cases of Ⅲ ~Ⅳ stage;Group C:30 cases hysteroscopic uterine septum resection with electricity due to lower mediastinal uterus were selected at the same period.The expression levels of DLL4 protein in Group A,B were detected by S-P method,and compared with the control group (Group C),then analyze its relationship with EMs stage. Results In Group A,B and C,the expression of DLL4 protein were (144.99 ±10.12 ),(1 15.42 ±10.39 ),(90.08 ±7.29 ),and there were significantly diffiences among three groups (F=314.220,P<0.05);The expression of DLL4 protein atⅠ~Ⅱstage were significantly lower than that inⅢ~Ⅳ stage (P<0.05).Conclusion DLL4 protein may play an important role in the pathogenisis of endometriosis.

[Objective] To summarize treatment ideas for subclinical thyroid inflammation by Professor WU Xuesu.[Methods] By learning from Professor WU Xuesu, studying relevant literature cases;collecting and reporting the case of her clinical characteristics for the treatment of subclinical thyroid inflammation, analyzed and summarized treatment experience. [Results] It is argued that the root of subclinical thyroid inflammation is turbid-phlegm, nitrogen stasis cardiac knoting in the anterior portion, it should be treated by resolving phlegm mainly,and secondary promoting Qi activating blood. [Conclusion] The treatment ideas of Professor WU Xuesu for subclinical thyroid inflammation has a good curative effect.

Objective Utilizing the characters of pyrrolidine dithiocarbamate known as a specific inhibitor of NF‐κB and imidapril known as a specific inhibitor of angiotensin converting enzyme ,this study was to initially investigate the relationship between NF‐κBp65 and AngⅡ during the process of myocardial ischemia reperfusion injury .Methods Rat models of myocardial ischemia reper‐fusion injury were successfully established .The observation point is 60 min of reperfusion after 30 min(I30 min R60 min ) ischemia ,the DNA activate of NF‐κBp65 was detected by ELISA ;the content of AngⅡ in blood plasma and cardiac were determined by radioim‐munoassay .We pretreated with pyrrolidine dithiocarbamate ,imidapril ,and both of them to observe changes of the same indexs .Re‐sults Compared with I30 min R60 min ,Pyrrolidine dithiocarbamate ,Imidapril and pyrrolidine dithiocarbamate add imidapril could all ob‐viously inhibit NF‐κBp65 activation and depress the content of Ang Ⅱ in blood plasm and cardiac ,the pyrrolidine dithiocarbamate add imidapril was most obviously .Conclusion During the process of myocardial ischemia‐reperfusion injury ,NF‐κBp65 had been activated ,and the content of Ang Ⅱ in blood plasm and cardiac had increased .NF‐κBp65 and AngⅡ could influence and promote each other during myocardial ischemia reperfusion injury .
