The different methods used in trehalose determination are introduced in the review. Comparisons on the characteristics and the applicational property of the methods are also discussed.

Objective:To study the job stress factors of drivers.Methods:Cluster analysis.Results:The job stress factors of drivers can be divided into six clusters,which are social support,negative state,job requiring,job control,stress level,and job busyness and monotony.Conclusion:Comprehensive measures should be used to reduce the job stress.

Objective To investigate the resilience of primary caregivers of cancer patients undergoing chemotherapy and explore the influencing factors. Methods General information questionnaire and Cornor-Davidson resilience scale (CD-RISC) were used in the survey among 173 cancer patients undergoing chemotherapy as well as their primary caregivers. Results The score of resilience of primary caregivers was (70.76 ±13.34), at middle or above level. Multiple linear regression analysis showed that caregivers'resilience was affected by gender, age, family income and religious belief (all P<0.05). Conclusion The resilience among primary caregivers of cancer patients undergoing chemotherapy is at a relatively high level. Clinically, we should pay more attention to female and young patients with lower family income and no religious beliefs.

By using traditional Chinese medicine inheritance support system to analyze the dominant experience and recessive principles of the prescriptions for stranguria in the dictionary of traditional Chinese medicine prescription (DCMP), we aim to define the medication pattern and rule and to acquire new prescriptions. In dominant experience analysis, we were able to find 22 drugs used over 50 times, including drugs of clearing heat, diuresis and relieving stranguria which are the most used and drugs of clearing heat, cooling blood, benefiting Qi and nourishing Yin. In addition, drugs of activating Qi and Xue, eliminating phlegm and removing toxic are often used, including 34 herb pairs and 5 combinations of three-taste drugs are used more than 35 times. These results fully reflect the composition principles and compatibility characteristic of prescriptions for treating stranguria in DCMP. Thirteen new prescriptions by way of recessive principle excavating were acquired. These new prescriptions might be suitable to clinical treatments of variable syndromes. This article provides an useful clue to research and produce new drugs.

More and more interest has been put on the investigations of saccharides recent years. Saccharides have a vast number of bioactivities and the immunomodulating effect of saccharides is one of the important mechanisms via which saccharides exert their bioactivities. Saccharides exert their bioactivities mainly by interacting with all kinds of saccharide receptors on cells, followed by a series of signal transduction process. In the present paper, numerous saccharide receptors and the characters of the mutual interaction between saccharides and their receptors are summarized.

To investigate the repairing effect of fibrochondrocyte collagen construct in meniscus lesion, fibrochondrocytes were isolated and expanded in vitro , then seeded onto collagen construct .18 dogs with wedged shape lesion in the lateral meniscus were randomly divided into 3 groups: the lesion were filled with either cell collagen construct or collagen or untreated. The lateral meniscus was then examined grossly and histologically at different periods. The results showed that the lesions that had been filled with fibrochondrocyte collagen construct healed with fibrocartilage tissue. The results suggest that tissue engineering method is practical.

To investigate the behavior of meniscal fibrocartilage cells in vitro ,human meniscal fibrocartilage cells were harvested from adolescents and sequentially digestied with 0 50% trypsin and 0 2% collagenase (type2). The isolated cells were cultured in Ham'sF 12 medium and identified by histochemical methods. Cell proliferation, morphology and ultrastructure were observed by phase contrast microscope and electronic microscope. In primarily cultured cells, fusiform cells dominated and they were confirmed by the positive result of immunohistochemical examination for type collagen staining. Our results indicate that it is a simple and highly effective method.

Sonic hedgehog(Shh) is a member of the hedgehog family in vertebrate. The Shh signaling pathway is mainly composed of a secreted glycoprotein, named Shh, two transmembrane proteins (Ptch and Smo) and the downstream transcription factor family Glis. It plays a vital role in the embryo development, especially in the neuronal system. Recent study have demonstrated that the Shh pathway is closely associated with the tumorigenesis of various tumors. Glioma, the most common malignant brain tumor of humans, is characterized by the rapid proliferation, infiltrative growth and high rate of relapse, and it is one of the brain tumors with poorest prognosis. Abnormal activation of multiple signaling pathways has been known to enhance the proliferation ability of glioma cells. Moreover, glioma is composed of various tumor cells and the glioma stem cells were endowed with the ability of self-renewal and unlimited proliferation, which plays a key role in the tumorigenesis, progress and relapse. Evidence has been found that Shh signaling pathway is closely assoicated with tumorigenesis of glioma. Herein we review the current knowledge on the components of Shh signaling pathway and its role in the tumorigenesis of glioma and glioma stem cells.

Objective:To investigate influence of living locations on the personality characteristics of the only child and none-only children in an air force academy.Methods:1921 cadets were tested by the Chinese version of the MBTI-G.Results:Scores of the only child cadets from cities on the Sensing-Intuition and Thinking-Feeling dimensions were higher than those of none-only children group from cities and those of the only child group from countries.The scores of them on the SN scale were 93.0?18.5,90.4?17.6 and 90.1?17.7(t=2.25,P=0.025;t=1.99,P= 0.048).The scores of them on the TF scale were 94.6?22.6,89.1?21.1 and 88.4?21.0(t=4.02,P
