Objective To construct a cDNA expression library of Humulus pollen and provide the basis for screening the major allergenic components and producing recombinant allergen of Humulus pollen.Methods Verdure Humulus pollen were collected and preserved in liquid nitrogen after being sift out.Total RNA was extracted from the Humulus pollen with trizol reagent,and cDNA was synthesized by RT-PCR with purified total RNA.Then the cDNA was digested by SfiⅠ and the fragments smaller than 400bp were removed by chroma spin-400 column,and the fragments longer than 400bp were ligated with ?TripIEx2 Vector.The library was packaged in vitro and a small portion of packaged phage was used to infect E.coli XL1-Blue MRF′ for titration.The diversity of the library and the length of the inserted fragments were analyzed by PCR.Results The cDNA expression library contained 5?10~(5) recombinants and the percentage of recombination was 90%.The average length of inserted cDNA fragments was about 1.02kb.Conclusion The constructed cDNA expression library contains appropriate contents and sizes of cDNA fragments and is qualified for screening target cDNA clone.

Objective:To investigate the sexual concept and sex status of pregnant women so as to instruct pregnant health care and improve living quality.Methods:112 random sample candidates who have mature fetus for delivery in hospital were chosen to investigate and analyze by means of self-edited questionnaires and Eysenck protracted sexual latitude scale test.Results:Both sex frequency and sex continuing time of pregnant women reduced remarkably;their knowledge on sex related to pregnancy was generally poor;average value of Eysenck protracted sexual latitude scale test was 5.25,lying below the average points;professionals and individual professionals have statistics differences in occupation team;the single-mode of sexual intercourse in the sex of pregnant women has the highest percentage.Conclusion:Pregnant women lack the related health care knowledge on sex,and their concept of sex is comparatively conservative,so they can not enjoy full sex and need further improvement.

Integrative medicine is the effective combination of dual diagnosis of Chinese medicine and western medicine.The combination can broaden the scope of clinical diagnosis and combine the local pathological changes with the overall response of the human disease.It can add a more comprehensive understanding of diseases for people.Clinically treated with combination of Chinese medicine and western medicine can achieve the complement of advantages.It is significant.Because the theory system of Chinese medicine compared with western medicine is different and the theory system of combination is not practical and standardized.The methods of clinical diagnosis and treatment are also different.So there are still some problems and deficiencies in the integrative medicine.In this study,through extensive literature research,as well as the clinical investigation in some integrative medicine hospitals and the collection of related clinical data,we compared and analyzed the academic ideas and different features of Chinese medicine and western medicine,analysed the status and the insufficience of current clinical integrative medicine.Finally,we put forward a series of effective strategies and methods for how to combine with integrative medicine in a specific,reasonable and effective way.

Objective:To investigate the acid resistance of tooth hard tissues irradiated by different power outputs of Er,Cr∶YSGG laser.Methods:Samples in laser groups were irradiated using Er,Cr∶ YSGG laser with the power outputs of 2.5,3.5 and 5 W for enamel and 2 W,3 W and 4 W for dentin,respectively.The calcium and phosphate ion dissolved was measured after decalcification in lactate buffer solution for 24 h.The atomic percentage of calcium and phosphate on the surface of samples was examined by X-ray energy dispersive spectroscopy and the morphological changes were investigated by SEM.Results:In all laser groups of enamel samples except 2.5 W group calcium and phosphate ion dissolved less than in control group and block group (P＜0.05).There's no statistic difference between different power groups.Compared with control group and block group,Ca/P ratio increased(P＜0.05).There's no statistic difference of the atomic percentage of Ca and P on the surface of dentin samples between each 2 groups.SEM observation showed that the surface of the laser irradiated samples was rouph,the space among enamel fibers was increased,the dentin around dentinal tuble orifice was protruded and looked like collar flange.Conclusion:Er,Cr∶YSGG laser irradiation with a range of power is effective in increasing acquired acid resistance of dental hard tissue.There was no relationship between laser power outputs and acid resistance.

Emodin is the main effective monomer of Rhubarb, which has a variety of pharmacological actions and valuable clinical applications.Recently, there are many reports about molecular mechanisms of emodin pharmacological actions,and they givehighly attention on the dephlogisticating and antineoplastic effects. These effects are achieved through affecting the concentration and transportation of ions, resisting of oxidation and free radical, and affecting the secretion of inflammatory factor and the enzyme activity and apoptosis and so on. This article summarizes the reports and hopes to provide theoretical basis for the practical application.

The striatum is involved in diverse behaviors which depend on intact dopaminergic innervation. Recent electrophysiological studies have revealed that dopamine alters both voltage dependent conductances and synaptic transmission, resulting in state dependent modulation of target cells. This review makes clear predictions about how dopamine should alter the responsiveness of striatal neurons to extrinsic excitatory synaptic activity.
