ABSTRACT

Production internship is an important teaching tache for undergraduate students to carry out engineering training by using professional skills, and it is a key starting point for fostering application-oriented talents in biotechnology. The Course Group of 'production internship of biotechnology majors' of Binzhou University is investigating application-oriented transformation for local regular colleges and universities, as well as fostering high-level application-oriented talents. By taking green fluorescent protein (GFP) polyclonal antibody as an example, the reform and practice on teaching content, teaching mode, assessment method, continuous improvement of curriculum were carried out. Moreover, the characteristics of the Yellow River Delta-Binzhou Biotechnology & Pharmaceutical Industrial Cluster were taken into account to intensify academic-enterprise cooperation. On one hand, this Course Group designed and rearranged the course contents, carried out essential training through online resources and platforms such as virtual simulation, and recorded, tracked and monitored the progress of production internship through practical testing and software platforms like 'Alumni State'. On the other hand, this Course Group established a practice-and application-oriented assessment method in the process of production internship and a dual evaluation model for continuous improvement. These reform and practices have promoted the training of application-oriented talents in biotechnology, and may serve as a reference for similar courses.

ABSTRACT

Objective To compare the traditional anterior transposition and anterior subcutaneous with blood supply of the ulnar nerve for the treatment of cubital tunnel syndrome.Methods Eighty cases with cubital tunnel syndrome were enrolled in the retrospective study from January 2009 to March 2013,40 cases (control group) were treated by traditional anterior transposition while the others (observation group) were treated by anterior subcutaneous with blood supply.According to the evaluation criteria of ulnar nerve,evaluated the function of patients and compared the scores of two groups and the improved rate of different level patients.Results The scores of two groups before surgery were (3.6 ± 0.4),(3.7 ± 0.5) scores,after surgery were (7.5 ± 0.9),(7.4 ± 0.6) scores respectively,there was significant difference between two groups before and after surgery (P < 0.05),but there was no significant difference between two groups (P >0.05).The improved rate of observation group was 87.5% (35/40),which was higher than that of control group [85.0% (34/40)],but without statistical difference (P > 0.05).In two groups the patients with middle scores showed no statistical significance in improved rate [90.0% (27/30) vs.96.4% (27/28)] (P > 0.05).Two treatments showed a significant difference for the low scores patients 8/10 vs.7/12 (P <0.05).Conclusion Anterior subcutaneous with blood supply of the ulnar nerve is better than traditional anterior transposition for the gross cubital tunnel syndrome patients.

ABSTRACT

Object To search for more bioactive alkaloids from Aconitum coreanurn through this fur-ther study. Methods The ethanolic extract from the root of A. coreanum was isolated by aluminium oxidecolumn chromatography, the constituent structures were elucidated mainly by their physicochemical prop-erties and spectroscopic (IR, ESI-MS,1 H-NMR, 13 C-NMR,1 H-1 HCOSY, HMQC, and HMBC)analysis.Results Seven alkaloids were obtained from the root of A. coreanum, they were identified as: 11, 13-di-acetyl-14-hydroxy-2-isobutyryl hetisine ( Ⅰ ), guan-fu base G ( Ⅱ ), guan-fu base F ( Ⅲ ), guan-fu base Z( Ⅳ ), guan-fu base I ( Ⅴ ), guan-fu base K ( Ⅵ ), and guan-fu aminealcohol (Ⅶ). Conclusion Compound I is a new natural product, named as guan-fu base P, its 1 H-NMR and 13 C-NMR data are reported first inthis paper.

ABSTRACT

AIM:To establish the chromatographic fingerprint of Carthamus Tinctorius L.by high performance liquid chromatography(HPLC).METHODS:The chromatographic fingerprint of Carthamus Tinctorius L.was established by HPLC with a RP-C_ 18 column,acetonitrile-water(0.5 phosphoric acid)gradient elution,a DAD diode array detector at 275 nm and the flow rate of 1.0 mL/min,column temperature of 25 ℃。 RESULTS:34 co-peaks of Carthamus Tiuctorius L.were gained from 10 producing provinces.Its basic features were rough consistent each other.Hydrosafflor yellow A,was selected as marker,among samples the content of Xinjiang was the highest in the all samples.CONCLUSION:This method provides useful information for identification of traditional Chinese medicines,the fingerprints of samples of Carthamus Tinctorius L.can be used to control the quality combined with content determination.
