Industrial culture media for cultivation of marine microalgae Nannochloropsis oculata was optimized by using Random Design software. High eicosapentaenoic acid (EPA) content was obtained over 40% of total fatty acid, and high average specific growth rate of 0.32d -1 was obtained in cells grown in the selected Formula 1. Mass cultivation of this species was practiced in indoor open raceway ponds of 6.12 m 2 and 28.02 m 2, and in outdoor open pond of 83.50 m 2 during May and June in 1999. The average area yield of biomass were obtained at 2.77, 1.62 and 2.52 g /m 2?d, and in October, 1.09 g/ m 2?d was obtained in 83.5m 2 outdoor pond, and the harvest algae powder contained 49.50% of protein, 20.30% of total lipid and 3.00% of EPA of dry weight. With high temperature tolerant species during August in 2000, the average area yield of biomass were increased to 5.44?9.96 and 7.66 g/ m 2?d in above ponds, respectively and 2.50% of EPA of dry weight was contained in the powder. It is indicated that the industrialized cultivation of Nannochloropsis oculata rich in EPA is completely doable on practice, and the algal powder was a good raw material as single cell protein and development of EPA rich products.

According to the project of personnel cultivation in 21st century,we have increased interdisciplinary comprehensive experimental courses to intensify the practical education,optimize operating model and teaching method of experimental courses.Experimental education must be strengthened in order to culture students' creativity.

Objective To analyze and discuss the effects of preserving the intercostobrachial nerve(ICBN)in modified radical mastectomy for breast cancer. Methods A total of 80 patients with breast cancer were randomly divided into the observation group and control group(n = 40 in each). The ICBN in the observation group were reserved and it was removed in the control group. Operation time,the number of lymph nodes,blood loss and complication rates were compared between groups. Two groups of patients were followed up for abnormal sensory function and relapse and metastasis. Results There were no differences in the operation time,the number of dissected lymph nodes and blood loss(P > 0. 05). There was no difference in complication rate(12. 50% vs 15. 00% )between the observation group and control group(P > 0. 05). There were significant differences in the incidence of abnormal sensory function at the first week(10. 00% vs 52. 50% ),the first month(5. 00% vs 47. 50% ),the third month(2. 50%vs 45. 50% ),the sixth month(2. 50% vs 37. 50% ),and the twelfth month(0. 00% vs 27. 50% )after op-eration between the observation group and control group(P < 0. 05). During the one-year follow-up peri-od,there was no relapse or metastasis. Conclusion Preserving ICBN in modified radical mastectomy can effectively reduce the incidence of abnormal sensory function of the upper limb.

False and negative information has brought forth serious impacts on doctor-patient relationship in the new media era as a result of “Broken window effect”and “Butterfly effect”.The underlying reasons are herd mentality,the public’s need to vent their discontent,the subjectivity of information distribution on the Internet and lack of proper supervision and punishment mechanism.Medical Institutions should pay special attention to the new media,leveraging it to improve doctor-patient relationship by making official voice,guiding public opinion,solving problems,and providing comfortable social environment and rational public opinion environment on the Internet.

The preparation of Calculus bovis and its compounding preparations have been used widely in clinical practice.Traditionally,the forms of medicine were in raw material medicine way,preparing tablet,pill,powder or directly taking its powder.The main active ingredient of Calculus bovi were considered to be bilirubin and bile acids.However,the traditional formulations caused low bioavailability and wasted expensive herbs because its main component were insoluble in water.In recent years,many researchers have tried to use modern preparation technology to prepare its compounding formulations,such as solid dispersion technology,ultrafine grinding technology,powder coating technology,liposome encapsulation technology,or simplifying the prescription by using of known pharmacological effects of soluble components as substitutes.These methods were considered to be feasible to develop new formulations of Calculus bovis.In this paper,in order to provide reference of method and technology for the improvement of Calculus bovis compounding preparation and the development of new dosage form,ultramicrostructure,chemical composition,improvement methods and techniques of compounding preparation were analyzed.In addition,the relevant techniques and method of improving the formulation Calculus bovis compounding preparation in recent years were reviewed.
