Great emphases should be placed on the cultivation of students' professional personality in vocational and technical colleges.This essay brings forward three cultivating stages including public and basic cultural quality training,basic medical vocational morality training,and professional medical personality training.Cultivating modes are also explored such as offering required courses of humanistic qualities in professional medical personality and a series of elective courses of professional medical personality qualities.This essay provides cultivating approaches including teaching program design,teaching process,teaching evaluation,teaching staff training,teaching means,practicing and skill training,and campus cultural construction to realize the transformation of medical students' cultivation from professional personality education to practical quality education.

Virus inactivation with photochemistry is being suitable for blood or blood products, methylene blue (MB)/light treatment has been used for viral inactivation of cellular blood components. Twelve new phenothiazines derivatives were designed and synthesized, and were used to test viral inactivation and red cell damage preliminary. Results showed that compound YWW-7 has a satisfactory activity, it could be developed as a new viral inactivation agent for blood products.

AIM:To establish the quality standard of Compound Shouwu Granule (Radix Polygoni multiflori,Radix et Rhizoma Thalictri Baicalensis,Herba Rabdosiae Rubescentis,etc.) METHODS:TLC was performed to identify Radix Polygoni Multiflori,Radix et Rhizoma Thalictri Baicalensis,Herba Rabdosiae Rubescentis.HPLC was used to determine 2,3,5,4'-tetrahydroxystilbene-2-0-?-D-glucoside. RESULTS:The study on the quality control showed that the characteristic of identification by TLC was distinct and highly specific.The quantitative evaluation had the linear range of 0.04-0.72 ?g.The average recovery was 99.99% and RSD was 1.3%. CONCLUSION: The method for identification and quantitation was simple,accurate,realizable and reproducible.It can be used effectively for the quality control of Compound Shouwu Granule.

Objective To establish the method of the GC fingerprints for Ligusticum chuanxiong essential oil and its quality control.Methods The temperature at both feed inlet and detector was 250℃,the carrier gas was nitrogen,and the flow rate was 2 mL/min.GC of the essential oil in ten batches of L.chuanxiong was analyzed by adopting temprature programmer and the fingerprint peaks were identified by GC-MS.Results To set up the GC fingerprints for L.chuanxiong essential oil,13 peaks were marked out altogether and the GC fingerprints were analyzed by similarity analysis.Conclusion The method is of high degree of presion,reproducibility,and stability.The resolving of each component in the essential oil is good.The established fingerprints could be used as one of the quality control index for L.chuanxiong essential oil.

Objective To observe the clinical effect of treating advanced esophageal carcinoma with three-dimensional conformal radiotherapy combined with chemotherapy and traditional Chinese medicine.Methods 36 cases with advanced esophageal carcinoma were randomly divided into a eontrol group and a treatment group.The control group was treated with conventional radiotherapy combined with chemotherapy,and the treatment group was treated with three-dimensional conforrnal radiotherapy combined with chemotherapy and traditional Chinese medicine.The short-term effect,toxicity and long-term effect were observed,and cause of death was analyzed.Results The complete remission rate in the treatment group was significantly higher than that of the control group(P＜0.05).The toxicity of the treatment group was markedly decreased.One and three years'survival rate between the two groups had a significant difierent(P＜0.05),but five years'survival rate between the two groups had no significant difference(P＞0.05).Local uncontrolled rate and recurrence rate in the treatment group were significantly lower than those in the control group(p＜0.05).Conclusion The treatment of three-dimensional conformal radiotherapy combined with chemotherapy and traditional Chinese medicine on advanced esophageal carcinoma was better than conventional radiotherapy combined with chemotherapy.

Aim To detect the effect of Bio on impro-ving insulin resistance and explore its molecular mech-anism. Methods The HepG2 liver cells were derivat-ed by high concentration insulin to establish the insulin resistance cell model, and the cells were intervened by Bio. The glucose consumption was measured by glu-cose oxidase and peroxidase ( GOD-POD) assay. The expression of PPARγmRNA was detected by RT-PCR. The expression of PPARγ protein was detected by Western blot method. Results The glucose consump-tion was significantly decreased in the insulin resist-ance cells after incubated with 1 . 72 × 10 -5 mol · L-1 insulin ( P<0. 05 ) . 10 -5 ,10 -6 ,10 -7 mol · L-1 Bio increased the glucose consumption 135%,62%,39%separately in the insulin resistance cells. RT-PCR a-nalysis of PPARγ showed that Bio raised the PPARγmRNA. Western blot analysis displayed that the pro-tein of PPARγ with Bio was increased. Conclusion Bio can improve the insulin resistance of the HepG2 cells, and the molecular mechanism may be relevant with raising PPARγ expression.

Objective To investigate the clinic effect of using three-dimensional conformal radiotherapy combining with Sanyangxuedai in treating advanced non-small cell lung cancer.Methods Grouping 100 patients with advanced non-small cell lung cancer randomly into a control group and a treatment group,with 50 patients in each.The control group was treated with three-dimensional conformal radiation therapy,the treatment group was treated on the basis of the control group with a ioint Sanyangxuedai.The clinical effects were compared in the two groups.Results The three-dimensional conformal radiotherapy combining with Sanyangxuedai had more better treating indications than using three-dimensional conformal radiotherapy only and the results had statistical significances(χ~2=12.01,P＜0.05).Conclusion The three-dimensional conformal radiotherapy combining with Sanyangxuedai had beaer clinical efrect in treating advanced non-small cell lung cancer.
