Objective To establish the methodology of flow cytometry for detecting human cells in human/goat chimerisra.Methods Human hemopoietic stem/progenitor cells (CD+34 cells) or MIG-tranadueed-GFP CD+34 cells were transplanted into the peritoneal cavity of fetal goats in utero to obtain human/goat chimera modeL The peripheral blood cells from the chimeras were labeled with multiple mouse anti-human antibodies and the monoelonal antibodies that were specific for human but had not or only minimal cross-reaction with goat were screened as the primary antibodies for routine analysis in flow cytometry.Human cord blood was proportionally (25% ,50% ,75%,100%) added into the blood of the untransplanted goats and the cells were labeled with CD+34 monoclonal antibody.The region and size of the "gate" were chosen based on to the distribution of CD+34 cells or human cord blood.One human/goat chimera marked with GFP (MIG goat) was sacrificed and the substantial liver cells from its perfused liver were analyzed for the GFP+cells percentage and DNA contents by flow cytometry.Results CD7,CD15,CD38,CD45CD20CD34CD14and GPA monoclonal antibodies were chosen as the primary antibodies in rou tine detection by flow cytometry.The size and area of the "gate" were also defined.29.1% (29100/100 000 ) of the substantial liver cells from the MIG goat expressed GFP.DNA content analysis showed that the GFP+ cells obtained from the liver of MIG goat mainly manifested two peaks that were correspond to those of human.Conclusions Flow cytometry is rapid,simple and effective for the investigation of differentiation,homing and biological characteristics of stem cells in vivo.The selections of suitable surface antibodies and the "gate" are very important for detecting human cells accurately in the human/goat chimerism.

Objective To evaluate the effect of slow-release microcapsules of HCF( hepatocyte growth factor) on angiogenesis in infracted myocardium.Method Myocardial infarction was induced in 30 New Zealand rabbits by ligating the middle of left descending coronary artery. Group Ⅰ ( n = 10) was served as a control group, group Ⅱ ( n =10) as a blank microcapsule group, group Ⅲ ( n = 10) as experimental group with each microcapsule contains 1 μgHGF as HCF group. In group Ⅱ andⅢ, 5 blank microcapsules or FGF slow-release microcapsules were implanted into myocardium under epicedium between the left descending coronary artery and left circumflex branch. The heart function of each rabbit was evaluated with echocar-diography and cheterization, angiogenesis was evaluated by immunohistochemical technique 6 weeks later.Result As compared with group Ⅰ and Ⅱ , rabbits treated with HGF had higher microvessel counts ( P < 0. 01), and LVFS and EF were significantly increased [ (101. 28±19. 50,105. 28 ±18. 28,161. 28 ±15. 85, P <0.01 ]. Conclusion Subepicardial implantation of HGF slow release microcapsule in the infracted rabbit model can enhance effective angiogenesis and improve left ventricular function.

OBJECTIVETo identify the human hematopoietic stem cells from the human/goat xenogeneic model with molecular techniques.

METHODSDNA and total RNA were extracted from 11 transplanted goat peripheral blood cells. Human CD(34), GPA and SRY genes were amplified with PCR in these samples, and CD(34), GPA mRNA transcripts were detected using RT-PCR in 5 and 6 goat peripheral blood cells, respectively. Southern blot analysis was performed in 8 goat DNAs to detect the human specific alpha-satellite sequence. Meanwhile FISH was also performed to detect the human cells in goat blood with a probe of human Y chromosome.

RESULTSHuman CD(34) and GPA genes could be detected with PCR in all the 11 goats, and SRY gene did in 5 goats transplanted with hematopoietic stem cells derived from male human babies. Southern blot showed that human specific alpha-satellite sequence was present in 8 goats. By RT-PCR, human CD(34) mRNA was detected in 5 experimental goats, GPA mRNA was found in the other 6 experimental goats and FISH assay showed that some peripheral blood cells of the human/goat xenogeneic model were positive.

CONCLUSIONExistence of human cells in the recipient goats was identified by molecular detection, which was feasible for the examination of human/goat xenogeneic models.

This article reviews studies on the heredity of personality disorders and family environment factors from the population-based studies, and summarizes the interaction between genetic factors and environmental factors. Studies have shown that there is a genetic basis for personality disorders, including family studies, twin studies, and neurophysiological studies. In addition, environmental factors, including social psychological factors, also play an important role in the development of personality disorder. In sum, the occurrence of personality disorder is the result of interactions between genetic factors and environmental factors. This paper snmmarizes sresearch on personality disorders, and investigates the role of interaction between genetic and environmental factors in the development of personality disorders. Such evidence has implications for effective prevention and intervention of personality disorders.

Objectives: To establish an intervention model of mental health education for personality disorders through community intervention study and to provide scientific basis for the early intervention of personality disorders. Methods: In Beijing, students from 25 high schools were selected as subjects of the study. Random cluster sampling method was used to divide all the schools into intervention group (13high schools) and non-intervention group (12 high schools), when the students werein the first grade. All of the schools were followedup for three years. According to the ICD-10 and DSM-IV criteria, PDQ-4 and the International Personality Disorder Checklist (IPDE) were used to screen and diagnose personality disorder. Associated influencing factors were collected using the Parental Rearing Questionnaire (Egma Minnen av Bardndosnauppfor-stran, EMBU) and the General Information Questionnaire. Univariate and multivariate analysis were used to analyze the data. Results: PDQ-4 scores of the intervention group were significantly lower than those of the non-intervention group. PDQ-4 scores and incidence rates of PD at the third grade were significantly lower than those at the first grade. Logistic regression analysis yielded risk factors of overall PD including poor parental relationship, parental rejection and over-protection. The incidence rate of personality dysfunction was 3. 4％ in the intervention group, and 4. 0％ in the non-intervention group. The incidence rate of PD was 0. 8％ in the intervention group, and 1. 1％ in the non-intervention group without statistical significance. The PDQ-4 score showed significant decline trend during the three years. But the prevalence rates had no statistical significant difference between intervention and non-intervention groups. Moreover, the prevalence rate of personality dysfunction significantly decreased after three years. The incidence rates of cluster C, as well as paranoid, narcissistic and borderline PD were statistically significantly decreased after the intervention. Conclusion:The mental health education during adolescence is effective and contributes to the promotion of mental health for adolescents.
