Fecal specimens of 35 parasitologically confirmed cases of giardiasis, 41 acute, gastroenteritis, 23 acute baciUary dysentery, 40 normal persons and 15 jirds experimentally infected with G. lamblia were tested with conterimmunoelectrophoresis (CIE). It was found that 33(94%) out of the 35 giardiasis patients and 14(93%) out of 15 infected jirds showed positive reaction, while fecal specimens of other cases, normal persons, or normal jirds all showed negative reaction. Besides, CIE was performed in 4 giardiasis patients before and after metronidazole treatment. Prior to metronidazole, they were all CIE positive, one day post metronidazole, 3 of them were still CIE positive, and Giardia cysts or trophozoites were also present in their stools. However, from the second day onwards, all of them became CIE negative, while cysts or trophozoites also disappeared from their stools. Apparently, detecting Giardia antigen in fecal specimens with CIE of feces is not only a sensitive tool for detecting current infection, but also a, useful tool for evaluating therapeutic effects in giardiasis.

The clinical efficacies were compared after a treatment course.Result The total effective rate was 93.3% in the treatment group versus 83.3% in the control group, and the difference was statistically significant (P<0.05).Conclusion Peng’s eye acupuncture is an effective method in treating headache.

This article was aimed to analyze literatures on preventive treatment of disease in acupuncture and moxi-bustion in order to understand its status and development trend. Bibliometrics and statistics method in NoteExpress were used in the analysis of related literatures about preventive treatment of disease in acupuncture and moxibustion from 1981 to 2013, which were included in CNKI. The analysis and research were from aspects such as year distri-bution, keyword, journal distribution, author distribution, and fund distribution. The results showed that there were 537 articles in total from 1981 to 2013. The number of literatures was in an overall growing trend.“Zusanli”,“Inner Canon of Huangdi”,“sub-health”, and“clinical research”were high frequency keywords. The journal distribu-tion conformed to the Brad Ford’s law. The author distribution conformed to the Lotka’s law. The number of fund papers was also increased. It was concluded that research on preventive treatment of disease in acupuncture and moxibustion was still in the period of rapid development and had not reached maturity. The preventive treatment of disease in acupuncture and moxibustion had broad application prospects. However, the research still required to be strengthened.

Objective To explore the functional expression and temporality of MDR1 gene in bone marrow of rabbits after autologous bone marrow transplantation with MDR1 transferred bone marrow mononuclear cells. Methods The supernatant of the amphotropic virus producer cell line PA317-HaMDR1/A was collected and concentrated to cocultivate with the bone marrow mononuclear cells of the rabbits. After large dose of chemotherapy with cyclophosphamide,the transferred cells were autotransplanted into the bone marrow. The integration,transfection rate and physiological function of MDR1 gene were tested by PCR,SP immunohistochemical method and daunorubicin (DNR) extrusion test respectively. Results After autologous bone marrow transplantation had been executed for 1-4 months,the integration of MDR1 gene in genome of bone marrow mononuclear cells was detected by PCR,and the expression rates of P-gp in cells tested by SP immunohistochemical method were 9.5%,8.5%,6.0% and 3.5% respectively. The physiological function of MDR1 gene in bone marrow cells was proved by DNR extrusion test. Conclusion After the autotransplantation with bone marrow mononuclear cells transferred by MDR1 gene,the MDR1 gene can implant into the bone marrow of rabbits and has expressed functionally for 4 months,which has provided a basis for further research on chemoprotection experiment of the MDR1 gene transferred into the bone marrow cells.
