Objective: To study the proper medium for tissue culture of the explants from Hypericum perforatum . Methods: The root, stem with node and leaf of the Hypericum perforatum seedling were used as explants, and cultured in basic Murashige and Skoog (MS) medium supplemented with different kinds and different concentrations of hormones. The callus, buds and roots were induced. The cultivation of the tube seedling were carried out. Results: Different hormones and explants had different effects on the induction of callus and the formation of buds. 2,4 D could promote the formation of the callus of Hypericum perforatum . Among cytokinins, 6 BA had great effect on the formation of buds, but the effects of KT and ZT were insignificant. The combination of NAA 1 mg/L and 6 BA 0.2 mg/L was found most effective in promoting the rooting of Hypericum perforatum . Conclusion: The results indicate that the callus is easy to be induced when MS medium supplemented with 2,4 D. The root of explants is most suitable for the rosette bud rapid induction.

Objective To explore the clinical efficacy of atorvastatin calcium in the treatment of chronic congestive heart failure(CHF).Methods According to the order of admission with single and double,132 CHF patients were randomly divided into control group and study group,66 cases in each group.The control group was given routine treatment,and the study group was treated with atorvastatin calcium on the basis of routine treatment.The clinical efficacy was assessed.Before and after treatment,the serum TC level was measured,the left ventricular ejection fraction(LVEF) and heart left ventricular end diastolic diameter(LVDD),heart index(CI) were assessed by echocardiography.The adverse reactions during treatment were observed.Results The total effective rate of the study group was 92.42%,which was higher than 83.33% of the control group,the difference was statistically significant(x2=9.35,P<0.05).The serum TC of the study group after treatment was (3.24±0.75)mmol/L,which was lower than (4.70±0.86)mmol/L of the control group,the difference was statistically significant(t=8.96,P<0.05).The level of LVEF of the study group after treatment was (46.39±6.35)%,which was higher than (44.60±5.82)% of the control group,the difference was statistically significant(t=9.47,P<0.05).The levels of LVDD and CI were (47.06±5.39)mm and (2.60±0.62)L·min-1·m-1 respectively,which were lower than (49.53±6.17)mm and (2.97±0.69)L·min-1·m-1 of the control group,the differences were statistically significant(t=10.31,9.40,all P<0.05).There was no significant difference in adverse reactions between the two groups(x2=2.04,P>0.05).Conclusion Atorvastatin calcium in the treatment of CHF patients on the basis of routine treatment has better clinical effect.It can significantly reduce TC and significantly improve cardiac function,and has high safety.

In order to maintain and develop the overall advantages and distinguishing features of medicine in Shanghai, the citys health system implemented the program of constructing centers for clinical medicine. The program involved not only the optimization and integration of health resources in the whole city but also the structural readjustment and resources regrouping within the citys health system and each individual hospital. After more than two years construction, 33 centers for clinical medicine have been set up in the city, resulting in primary achievements in expertise improvement, effect of scale, and quality benefits. By analyzing the hardware and software construction process, it can be seen that the centers for clinical medicine have made primary achievements in such aspects as ideological construction, work efficiency, interdisciplinary cooperation, academic status enhancement, medical quality improvement, and reform in the system of personnel distribution.

Object To establish the culture system of hairy root of Eclipta prostrata (L.) L.. Methods Hairy root of E. prostrata was obtained from infected cotyledon explants after infection with Agrobacterium rhizogenes strains A4, R1601 and ATCC15834, elite strains were screened and growth curves determined. The transformation of Ri T DNA was examined through high voltage paper electrophoresis. Results The hairy root was originally obtained from E.prostrata. The result of high voltage paper elctrophoresis confirmed the transformation of T DNA from Ri plasmid to the hairy root. Conclusion The acquisition of hairy root of E. prostrata provided further a foundation for the industrial production of active drug component.

Objective: To establish the culture system of hairy root of Isatis indigotica and to induce the regeneration plant of hairy root. Methods: Hairy root of Isatis indigotica was obtained from infected cotyledon explants after infection with Agrobacterium rhizogenes strains A4, R1601 and ATCC15834. The better lines were selected. The growth curve was surveyed and extrinsic factors affecting the growth of hairy roots were investigated. The regeneration plant was induced on MS media with different hormones. The transformation of Ri T DNA was examined through high voltage paper electrophoresis. Results: The hairy root was originally obtained from Isatis indigotica . The regeneration plant was induced on MS media with BA. The result of high voltage paper electrophoresis confirmed the transformation of T DNA from Ri plasmid to the hairy root and regeneration plant. Conclusion: The acquisition of hairy root of Isatis indigotica and regeneration plant of it lay a foundation for the production of active component and introduction of foreign gene. [

The establishment of a scientific salary system is a key measure to improve the incentive and re-straint mechanisms, adjust and optimize the relations of the production, release the reform “bonus”, and is also an important health care reform today. In order to establish a scientific salary system of medical personnel adapting to the health industry characteristics, the paper makes an investigation on the salary level in the years of 2010—2012 in Shanghai, and analyzes the main problems of the present performance pay policy. On this basis, starting from the point of the health industry characteristics, the paper builds the salary system of medical personnel containing the comprehensive budget management, theoretical workload for approval, authorized personnel, performance appraisal and distribution, structural proportion within the industry, fund distribution management through the establishment of the salary level’s average wage and social linkage mechanism, and builds a theoretical framework on salary system of medical personnel in Shanghai.

During the course of standardized residents training,the performance appraisal management of the residents was used besides other regular management methods.The allowances of residents were decided monthly by the evaluation and assessment of many kinds of tests or examinations.Through this new measure,the learning enthusiasm of residents could be fully motivated.The authoritative effectiveness of management was enhanced enormously.Meanwhile,the quality of the educational and training has also been improved greatly.This method could be very useful for the training process.

Objective To study the surgical techniques of the extended subfrontal epidual approach to resect chordoma in skull base.Methods 18 cases of chordoma in skull base treated mierosurgically were analyzed retrospectively.Results Total resection were achieved in 15 patients(83%),gross resection in 3 patients(17%).There was no complication in all cases.Conclusion The microsurgery for chordoma in skull base via the extended subfrontal epidual approach is of the benefits such as clear and wide fields of vision,and minimize brain trauma.Lumber drain placement and the skull base reconstruction could improve the rate of total tumor removal and reduce complications.

The authors discussed about how to integrate the advantages of different medical research resources to construct Shanghai Academy of Medical Sciences,which will provide substantial support for medical innovation in Shanghai.Principles were proposed concerning the administrative system and management mechanism to enhance the performance.The Academy is expected to improve medical research and clinical performance,especially to help resolve some major diseases and incurable diseases.Ultimately,the Academy will develop into an advanced research center linking laboratory research and clinical medicine.

This study surveyed medical research institutions in Shanghai for the structure set, input and output, development orientation, bottleneck and other aspects. Problems were found with their relationship management, discipline arrangement, research efficacy and else.
