Objective:To analyze the relationship between hepatitis B virus(HBV)gene mutation at 1896 in precore region with genotype and replication of HBV and the liver function of patients.Methods:HBV precore 1896 site mutation,the genotype of HBV and serum content of HBV DNA were determined by PCR in 60 patients positive of HBV DNA.Chemiluminescence miacropaticle immunoassay(CMIA)was used for detection of serum HBeAg and HBeAb.Liver function parameters were ob- tained by routine biochemistry method.Results:The alanine aminotransferase(ALT)level in HBV with 1896 site mutation was significantly higher than that in the wildtype virus.Site mutation at 1896 had no correlation with HBeAg,HBV genotype and HBV DNA content.HBV DNA content in patient with genotype C was significantly higher than that with genotype B(P

Choosing the right solvent and timely use is the basis of rational drug use and the most direct and efficient way to improve the safety of traditional Chinese medicine injections. This study aimed to evaluate the influence of solvent and drug preparation time on Shuanghuanglian injection inducing pseudo-allergic reactions with mouse mode. The two tests were carried out: (1) Comparative experiment between different solvent: Shuanghuanglian injection preparation to the appropriate concentration with 0.9% sodium chloride injection and 5% dextrose injection, mixed with Evans blue, at one time intravenous injected into mice, 30 minutes later, the mouse ears vascular permeability were observed and compared. (2) Comparative experiment among different preparation time: placed 10 min, 2.5 h, 6 h and 24 h after Shuanghuanglian injection were prepared and then to detect the pseudo-allergic reactions in mice using the same methods as in (1). The results showed that there was no significant difference in the pseudo-allergic reactions in mice which induced by the same dose of Shuanghuanglian injection, respectively with 0.9% sodium chloride injection and 5% dextrose injection preparation, and with the extension of preparation time, the degree of pseudo-allergic reactions of Shuanghuanglian injection was gradually severe.

To evaluated the pseudo-allergic reactions of cordate houttuynia, pulse-activating and Qingkailing injection in mice, the ICR mouse were divided into different test groups, then were intravenously injected with three traditional Chinese medicine injections, positive control compound 48/80 and physiological saline as normal control. All test substances were mixed with 0.4% Evans blue. The reaction and vascular permeability of the ears were observed and measured 30 min after injection. At the same time, the mechanisms of the traditional Chinese injections' pseudo-allergic reactions was studyed. ICR mice were injected with the test substances as above without EB, blood in a part of mice were collected after 5 min, and the level of histamine in the plasma were measured. Blood in the other part of mice were collected after 30 min, and the level of VEGF, TNF-α and IL-10 in the serum were measured. The reasults showed that except the cordate houttuynia injection, pulse-activating injection in 1. 5 times clinical concentration and Qingkailing injection in 3.3 times clinical concentration caused mild pseudo-allergic reactions mainly for vascular permeability, no pseudo-allergic reactions occurred when the concentration of the two injections was below the concentration metioned above; 5 minutes after intravenous injection of the three TCM injections into ICR mice with the highest dose, the levels of histamine in plasma of pulse-activating injection and Qingkailing injection groups were increased significantly, 30 minutes later, the levels of VEGF, TNF-α and IL-10 in the serum of all groups were no significant change compared to normal group. The mouse of pulse-activating and Qingkailing injection groups showed inflammatory changes in ear and lung tissues. It can be conluded that when the dose or concentration increased to a certain extent, pulse-activating and Qingkailing injection could induce pseudo-allergic reactions on ICR mice, the increased histamine realease maybe the main reason for pseudo-allergic reactions of the two traditional Chinese medicine injections. In addition the author preliminary thought that inflammatory mechanisms leading to hyperpermeabilities were the main reason of the traditional Chinese medicine injection's pseudo-allergic reaction.

Tibetan Herbal medicine has its own complete theory based on five sources doctrine. And the theories of "Liuwei", "Baxing" and "Shiqi Gongxiao" formed the basic core components of the property theory of Tibetan medicine. However, books and literature of Tibetan medicine have never been systematically expounded and discussed about it specially which thus will limit the further development of Tibetan medicine theory. In this thesis, we firstly introduced three basic core components of the property theory-the "Liu Wei", "Baxing", and "Shiqi Gongxiao" and their interactions as well. At the same time, the links and similarities between the theory of Tibetan medicine and Chinese medicine theory were compared. The job of the thesis done above is to lay the foundation for further systematic reveal and development of Tibetan medicine theory.

OBJECTIVETo develop a method to obtain and identify human coronary artery endothelial cells obtained during percutaneous coronary interventions (PCI).

METHODSCoronary guide wires were used to obtain endothelial cells from coronary arteries in 28 patients undergoing PCI. The cells were eluted from the wire tips and then purified by magnetic beads coated with anti-CD146 antibody. von Willebrand factor (vWF) was used as an immunocytochemical marker for endothelial cells. The cellular viability was evaluated by observing cell membrane integrity and energy-dependent uptake of DiI-labeled acetylated low-density lipoprotein.

RESULTSAn average of 96 coronary artery endothelial cells with good viability per patient were obtained by one guide wire. vWF identification showed their endothelial morphology and immunoreactivity.

CONCLUSIONThe viable coronary endothelial cells could be obtained during routine percutaneous coronary interventions combined with magnetic beads isolation technique. These cells may be used for further cellular functional analyses (such as immunocytochemistry and molecular biology) and expand our understanding on mechanisms of coronary artery diseases.

OBJECTIVETo investigate the psychological stress in the survivors of the May 12, 2008 Wenchuan earthquake transferred to Guangzhou for treatment, and explore the association between the psychological stress and the physical injuries related to the earthquake to promote both the physical and psychological recoveries of the survivors.

METHODSFifty-five earthquake survivors, including 27 with 28 without physical injuries, were transferred in our hospital 1 week after the earthquake. The Posttraumatic Stress Disorder (PTSD) Checklist-Civilian version (PCL-C) and the Self Reporting Questionnaire (SRQ) were used to investigate the psychological stress in these survivors.

RESULTSThe earthquake caused serious psychological stress in these survivors, and 43.63% of the survivors had high PCL-C scores (50 or above) and 78.18% had high SRQ scores (over 7), with 41.82% having high scores for both PCL-C and SRQ. The survivors with physical injuries generally had high PCL-C and SRQ scores (49.780-/+14.503 and 12.110-/+4.619, respectively), which, however, were not statistically different from the scores of the survivors without injuries (44.460-/+13.206 and 10.460-/+5.000, respectively, P>0.05). The injured survivors showed high scores for the subscales of persistent avoidance symptoms and of anger and irritability, in which the item scores for "efforts to avoid activities or places that arouse recollections of the earthquake" and "feeling of detachment or estrangement from others" were significantly different between the survivor with physical injuries and those without (P=0.034 and 0.018, respectively).

CONCLUSIONThe Wenchuan earthquake causes serious psychological stress in the survivors, and the wounded are more inclined to have persistent avoidance symptoms and enhanced irritability. In addition to the care of the physical injuries, psychological counseling and social support may help ameliorate the psychological trauma in the survivors and reduce the incidence of PTSD.

By studying the literatures on the adverse reaction of Yuxingcao injection, the clinical features of ADR were summed up, and the causes of ADR were analyzed through raw material, technology, chemical composition, compatibility and the clinical usage. The causes of ADR induced by Yuxingcao injection are complicated, maybe both due to the medicine itself and the incorrect clinical usage. Multi-measures including manufacture, techniques, clinical usage and some other cases should be taken to prevent the occurrence of adverse reaction of Yuxingcao injection.
