A series of multinuclear diethylenetriamine ligands were synthesized and used as artificial nuclease enzyme model. Target compounds were characterized by 1H NMR, 13C NMR, IR and ESI-MS. Preliminary studies on the cleavage of pUC19 DNA in the presence of metal complexes have also been performed and the results revealed that these complexes could act as powerful catalysts for the cleavage of pUC19 DNA after 48 h under physiological conditions. The hydrolytic cleavage mechanism of DNA plasmid by title compound was confirmed by T4 DNA ligase experiment.

Objective To explore the role of clinical pharmacist in individualized treatment of hypertension.Methods A patient withH hypertension receiving pharmaceutical care from clinical pharmacists was retrospectively analyzed.Results Patient's MTHFR (C677T) gene type was TT homozygous.Clinical pharmacist suggested doctor modify treatment,and then patient's plasma homocysteine dropped from 61.5 to 16.0 μmol·L-1,and blood pressure dropped from 173/ 111 mmHg(1 mmHg =0.133 kPa) to 130/80 mmHg.Conclusion Clinical pharmacist provides individualized treatment for patient with hypertension to ensure the safety and effectiveness of the drug by genotyping.

Group A,the differences among the three groups were statistically significant(P0.05). TCR,CCR,DAP,OD,BRC in Groups B and C showed trends of increasing,the differences in terms of the contents of BMP-RⅠamong the 3 phases were statistically significant(P0.05);the ER in Group B and C showed a trend of decreasing,thee difference between 4- and 8-week and 4- and 12-week were signifieantly dif- ferent(P0.05).Conclusion After application of glucocorticoid for a short term,pathological changes maintained and showed trends of inereasing in early stage.HBO can reverse these changes.The outcome of 3-course HBO therapy is better than that of 1-course therapy.

Objective:To explore the value of two-dimensional speckle tracking echocardiographic imaging (2D-STI) for assessing partial and global left ventricular functional changes at pre-and post-percutaneous coronary intervention (PCI) in patients with chronic total coronary occlusion.
Methods:Echocardiograph was conducted in 23 chronic total coronary occlusion patients at pre-PCI and 1 day, 3, 6 months post-PCI to examine left ventricular ejection fraction (LVEF), meanwhile 2D-STI was applied to obtain the global longitudinal strain (GLS) value of left ventricle.
Results:In all 23 patients, for LVEF, compared with pre-PCI (59.29±12.15)%, it was increased at 3 and 6 months post-PCI (60.00±12.35)%and (61.37±11.8)%respectively, all P<0.05;for GLS value, compared with pre-PCI (-12.77d wit )%, it was decreased at 1 day and 3, 6 months post-PCI (-13.23ecrea)%and (-15.67ecrea)%, (-16.97ecrea)%respectively, all P<0.05.
Conclusion:PCI could effectively improve left ventricular function in patients with chronic total coronary occlusion, 2D-STI technology may quantitatively assess those changes at the early stage.

Objective To investigate the changes and correlation of mitral valve coaptation length index CLI and coaptation area index CAI after mitral valvuloplasty MVP Methods A total of 30 subjects undergoing MVP for mitral regurgitation MR were studied Coaptation length CL CLI coaptation area CA and CAI were determined before and after surgery by 2-dimensional transoesophageal echocardiography 2D-TEE and 3-dimensional transoesophageal echocardiography 3D-TEE Results Compared with preoperative measurements CL CLI CA and CAI were significantly increased in postoperative studies CL 4 7±0 7 mm vs 9 4± 1 1 mm CLI 9 1 ±3 3 vs 38 5 ±4 1 CA 148 9 ± 65 3 mm 2 vs 371 9 ± 144 3 mm 2 CAI 9 3 ±3 1 vs 35 9 ± 7 5 all P < 0 05 CLI was significantly correlated with CAI both preoperatively r = 0 770 P < 0 01 and postoperatively r = 0 771 P <0 01 Furthermore CLI and CAI were significantly negative correlated with the degree of MR r =-0 897 P <0 01 r =-0 886 P <0 01 Conclusions Coaptation variables increased significantly in subjects after MVP CLI by 2D-TEE was related to CAI by 3D-TEE and both were useful for the assessment of mitral valve coaptation But CLI by 2D-TEE was more simple and feasible in clinic.

Objective To establish the primary cat intestinal epithelial cells(IECs)culture methods and construct the cD-NA library for the following yeast two-hybrid experiment,so as to screen the virulence interaction factors among the final host. Methods The primary cat IECs were cultured by the tissue cultivation and combined digestion with collagenase XI and dispase I separately. Then the cat IECs cultured was identified with the morphological observation and cyto-keratin detection ,by using goat anti-cyto-keratin monoclonal antibodies. The mRNA of cat IECs was isolated and used as the template to synthesize the first strand cDNA by SMARTTM technology,and then the double-strand cDNAs were acquired by LD-PCR,which were subsequently cloned into the plasmid PGADT7-Rec to construct yeast two-hybrid cDNA library in the yeast strain Y187 by homologous recom-bination. Matchmaker?Insert Check PCR was used to detect the size distribution of cDNA fragments after the capacity calcula-tion of the cDNA library. Results The comparison of the two cultivation methods indicated that the combined digestion of colla-genase XI and dispase I was more effective than the tissue cultivation. The cat IECs system of continuous culture was established and the cat IECs with high purity were harvested for constructing the yeast two-hybrid cDNA library. The library contained 1.1× 106 independent clones. The titer was 2.8 × 109 cfu/ml. The size of inserted fragments was among 0.5-2.0 kb. Conclusion The yeast two-hybrid cDNA library of cat IECs meets the requirements of further screen research,and this study lays the foundation of screening the Toxoplasma gondii virulence interaction factors among the cDNA libraries of its final hosts.

OBJECTIVETo search for an optimum method for testicular prothesis implantation in the treatment of testis loss.

METHODSWe retrospectively analyzed the surgical methods and outcomes of 53 cases of terminal prostate cancer and 4 cases of unilateral testicular torsion treated by implantation of testicular prothesis with the polypropylene mesh.

RESULTSThe 57 male patients all received testicular prothesis with the polypropylene mesh. All the patients were satisfied with the appearance and size of the scrotum after surgery. No scrotal hematoma, prosthesis infection, or autoimmune disease occurred postoperatively.

CONCLUSIONTestis loss is not a rare condition clinically, for the treatment of which surgical implantation of testicular prothesis with the polypropylene mesh can achieve both a fine tissue compatibility and a desirable scrotal appearance.

Ethnic medicine industry is facing many problems such as narrow market, exhaustion of resource, decline of ethnic medicine and no qualified successors. Sustainable development theory was utilized to analyse the elements and problems of ethnic medicine industry, and the counter measures were put forward to get rid of the predicament and to realize the sustainable development which depends on the ethnic medicine resources, national medicine, industrial policy, personnel training and modern technology. The development issues of ethnic medicine industry can be solved by the coordination of enterprise, government and public. Finally the ethnic medicine can provide better services for society.
