Biology-related disciplines in medical school of comprehensive university are cur-rently confronted with some difficulties, including unclear position and indistinguishable characteris-tics. In this paper, we proposed that biology-related disciplines in medical school of comprehensive university should center on disease research, emphasize medical feature and give full play to its tech-nical advantage thus to provide technical support for basic medicine and clinical medicine. Mean-while, sources of multiple disciplines should be effectively integrated by breaking through the limitation of discipline and administrative system. An interdisciplinary molecular medicine platform was built up for researching and teaching.

The health information social service in medical college and university libraries was analyzed in terms of the importance attached to it, opening to readers, items of service, requirement of materials, types of readers, and charge of frees, and certain measures were proposed for improving the level of health information social service, such as updating the service concept, innovating the service, and standardizing the management.

Brucella organisms are facultative intracellular bacteria capable of surviving inside professional and non-professional phagocytes.Upon cell contact the bacteria is internalized via receptor molecules.Once inside cells,Brucella localizes in early phagosomes,where it avoids fusion with late endosomes and lysosomes.Then,the bacterium redirects its trafficking to autophagosomes and finally reaches the endoplasmic reticulum,the replicating niche.Once inside the endoplasmic reticulum,Brucella extensively replicates without restricting basic cellular functions or inducing damage to cells.Invasion,intracellular trafficking and replication of Brucella organisms in professional and non-professional phagocytes and the molecular determinants involving Brucella intracellular life are reviewed in this article.

The bioactivity of a working reference standard was determined by replicate bioassays with calibration against a primary reference standard. In this study the number of bioassay replicates needed for calibration first was calculated theoretically, and if the mean value of the experimental bioassay replicates fell within the predefined bioactivity level the bioactivity of the working reference was defined as 100%. Our results showed that when the total intermediate precision of the bioassay method was at 11.66% and the predefined bioactivity level was set at 95%-105% with a confidence level of 95%, 21 bioassay replicates should be carried out for calibration. The average value of the 22 experimental bioassay replicates was 101.96%, so the bioactivity of the working reference standard was consistent with that of the primary reference standard at 100%. The results suggest that a strategy of first calculating the number of bioassay replicates needed for calibration and then determining whether the resulting experimental mean value is within the predefined bioactivity level will be of value to the biopharmaceutical industry.

Objective:To make a preliminary application of the assessment system for cancer pain management and find insuffi-ciency in the clinical practice of cancer pain diagnosis and treatment. Methods:Data from 41 doctor questionnaires, 43 nurse question-naires, 50 patient questionnaires, and 12 ward questionnaires from the tumor departments of 3 hospitals were analyzed, and the insuffi-ciency in cancer pain management was determined. The wards in the tumor and non-tumor departments related to oncology were as-sessed using rank test, and differences between the 2 wards were investigated. Results:The average scores of doctor, nurse, and wards were 85.41±5.93, 88.46±5.09 and 83.75±3.11, respectively, whereas patient score was 68.67±7.14. To further analyze the patient subsys-tem by converting into a hundred-mark system, the effectiveness and safety scores for the pain management was 81.69±7.71. However, patients' opinion score on pain treatment was only 55.78±11.37. The score of tumor departments was 82.22±2.03, whereas related non-tumor departments had a score of 39.27 ± 3.58. Wilcoxon W value was at 120.0 with P<0.01 after rank test. Conclusion:Education on patients' opinion on cancer pain management should be promoted in the tumor wards, and continuous education on cancer pain diagno-sis and treatment is needed in the non-tumor departments relative to oncology.

Total paeony glycoside (TPG) is extracted and purified from a traditional Chinese herbal medicine. It has many biological and pharmacological activities. However, there are few dosage forms of TPG in the market because of its low bioavailability. Self-microemulsifying drug delivery system (SMEDDS) is a vital tool in solving low bioavailability of poor absorption drugs. So the objective of this study is to develop a new TPG-SMEDDS for the oral delivery of poorly soluble TPG. Through the construction of pseudo-ternary phase diagrams, the optimum prescription was obtained, which consisted of 18.70% TPG, 16.27% ethyl oleate as oil, 43.34% Cremophor RH40 as surfactant and 21.73% Transcutol P as cosurfactant. The characterizations of TPG-SMEDDS including morphological characterization, droplet size, zeta-potential, emulsification time, and dissolution study of TPG-SMEDDS were evaluated. The results showed that TPG-SMEDDS is stable and its release rate is high in four different media (0.1 mol x L(-1) HCl, pH 6.8 PBS, pH 7.4 PBS, and water). The relative bioavailability of SMEDDS was dramatically enhanced in an average of 1.52-fold that of TPG-suspension. It is concluded that the bioavailability of TPG is enhanced greatly by SMEDDS.

Qualitative research methods are becoming more and more important in medical research area. Some qualitative researches played important roles in the exploration and the spread of core ideas of Chinese medicine. The report of qualitative research should be transparent and credible according to the standardized report criterion. On the basis of 22 criteria, the Consolidated Criteria for Reporting Qualitative Research (COREQ) was developed and published in September 2007. This introduction to COREQ will be helpful to Chinese qualitative researchers and readers in the implementation of high quality of medical qualitative research in China.

Pullulan is a linear glucosic polysaccharide produced by the polymorphic fungus Aureobasidium Pullulans, which has long been applied for various applications in medical and food industry due to its security, stability and low adhesive ability.At present, the two problems in restricting pullulan industrial production are the low polysaccharide production and melanin secreted which is hard to erase completely, giving the following process some problem.As a starting point, this review article collects and analyzes the progress on the breeding of pullulan high-yield strain without melanin in recent years, in order to find more efficient strains breeding methods, laying a foundation for further breeding of pullulan high-yield strain without melanin.
