Berbamine ( Ber. ) is a bis-benzyl-isoquinoline alkaloid isolated from the traditional Chinese medical herb, Berberis poiretis, and has Vide pharmacological effects. Clinical studies have demonstrated that Ber. had an effect of ingreasing the number of leukocytes in various leukocytopenia. But, up till now it has not been reported that Ber. take effect on enzymic metablism of inner cell and isoenzyme in the process of increasing leukocyte. The experiment observed the mice dynamic change of LDH in leukocyte and LDH isoenzyme of serum by cytochemistry and plane polyacrylamide gel electrophoresis tech-nigue. The result indicates that LDH enzyme reaction of granulocyte have increased in Ber. group and intensity of enzyme reaction has a positive interralation with the time of administrations. All specimen show 5 zones after LDH isoenzyme pattern analyse. The proportion of LDH-5 was changed and LDH-5 sub-band was detected in control and combination group. The experiment indicated that Ber. can affeet enzymic metablism of inner cell in the process of increasing leukocyte. There was simultaneously with a change in ratio of LDH isoenzyme pattern.

We summarized our accumulated clinical and teaching experiences and explored the regularity of acupuncture needling and teaching. It is of great importance in pressing hand during inserting needle. Stroking and pressing are two crucial parts which deserve more attention, and seldom useage of pressing hand should be abolished. Operating hand needs practice before inserting needle, while it should fully relaxed during inserting. Blending "touching", "stretch" "gathering" "erupting" and "advancing" in single moment, applying appropriate dynamic mode of inserting needle such as "join 3 forces as one" "3 points in a line" expertly and naturally. In addition, enough attention should be paid on "altering direction" and "shifting point". Inserting deftly and powerfully, no/slight sensation, deqi when inserting needle are the highest reflection as an acupuncturist.

A new method to measure arterial baroreflex-blood pressure control (ABR-BP) in conscious rats was established in our laboratory. ABR-BP was quantitatively determined by comparing the pressor responses to All before and after the blockade of the efferent pathway of baroreflex. It was found that there was a close relationship between Hood pressure variability and ABR-BP rather than arterial baroreflex-heart period control. ABR-BP was significantly lower in SHR and RVHR than in WKY rats. The lower ABR-BP in SHR was due mainly to the impairment of parasympathetic component

Objective:To observe the effect of Tuina(Chinese therapeutic massage)combined with functional training in improving clinical symptoms and balance function in patients with meniscus injury. Methods:A total of 93 patients with grade Ⅰ-Ⅱ meniscus injury were randomly divided into a functional training group,a Tuina group,and a combination group,with 31 cases in each group.The Tuina group received Tuina manipulation.The functional training group underwent functional training under the supervision of physicians.The combination group received Tuina manipulation in addition to the functional training.The treatment course of all three groups was 8 weeks.The clinical symptoms were observed before the intervention and after 4 and 8 weeks of interventions,and the changes in knee injury and osteoarthritis outcome score(KOOS)and Y-balance test(YBT)were compared. Results:There was no statistically significant difference in the total response rate among the three groups after treatment(P>0.05).The total and subscale KOOS in the three groups were significantly higher than those before treatment after 4 and 8 weeks of interventions(P<0.05).There was a statistically significant difference in the total KOOS between the combination group and the functional training group after 4 and 8 weeks of interventions(P<0.05);there was a statistically significant difference in the score of daily living ability and sports and recreation function between the two groups after 8 weeks of interventions(P<0.05).The YBT balance coefficients of the affected and non-affected knees of the three groups were significantly improved after 4 and 8 weeks of interventions(P<0.05),and there was no statistically significant difference among the groups(P>0.05). Conclusion:Tuina,functional training,and their combination can improve clinical symptoms and balance function in patients with grade Ⅰ-Ⅱ meniscus injury.Tuina combined with functional training is significantly effective in improving daily living ability and sports and recreation function.

Objective To construct a recombinant Bacillus Calmette-Guerin ( BCG ) vaccine strain, rBCG::Rv3478-pMV261, expressing the Rv3478 protein of Mycobacterium tuberculosis and to inves-tigate its immunogenicity.Methods The gene fragments encoding Rv3478 antigen were amplified by PCR and then respectively cloned into pMV261 and pET-28a vectors to construct the recombinant expression plas-mids (Rv3478-pMV261 and Rv3478-pET-28a).The Rv3478-pMV261 plasmids were transformed into the BCG cells to construct the rBCG vaccine strains, while the Rv3478-pET-28a plasmids were transformed into Escherichia coli BL21 strains for the expression of Rv3478 protein.Polyclonal antibodies were induced in mice upon the immunization with Rv3478 protein.The rBCG vaccine strains overexpressing Rv3478 protein were screened out with Western blot assay.The C57BL/6 mice were divided into four groups including the PBS treated group, BCG treated group, rBCG::pMV261 ( R0) treated group and rBCG::Rv3478-pMV261 ( R3) treated group.All mice were sacrificed in 4 or 12 weeks after immunization.Enzyme-linked immunos-pot assay ( ELISPOT) , ELISA and flow cytometry analysis were performed to evaluate the induced humoral and cell-mediated immune responses in mice.Results The Rv3478 protein was successfully expressed and could induce polyclonal antibodies in mice.High levels of IFN-γand TNF-αwere detected in mice treated with R3, indicating that the immunization with R3 enhanced the cellular immunity.Moreover, the ratios of CD4+to CD8+T cells and the percentages of CD44+CD62L+T cells were increased in mice upon the immuni-zation with R3.Conclusion The recombinant BCG vaccine strain overexpressing Rv3478 protein could in-duce stronger cell-mediated immune responses in mice.It might be have a great significance as a new tuber-culosis( TB) vaccine strain against TB infection in the future.

Objective To investigate the incidence of and clinical factors influencing neonatal birth defects from different assisted reproductive technology. Methods Between October 1998 and December 2006,1271 newborns from mothers treated by in vitro fertilization techniques [ including in vitro fertilization (IVF), intracytoplasmic sperm injection (1CSI) and thaw embryo transfer (Thaw-ET) ] matched with 269 newborns from mothers treated by artificial insemination were enrolled in Reproductive Medicine Center in First Hospital Affiliated to Zhengzhou University. Their medical information was analyzed retrospectively to compared neonatal characteristics, the incidence of birth defect and anomalous organs involved between in vitro fertilization group and artificial insemination group. Results In group of in vitro fertilization, those newborns with low birth weight from IVF, ICSI and Thaw-ET were 20. 0% ( 134/671 ), 22. 4% (92/410), 18.9% (36/190)respectively, which were more than 11.5% (31/269) cases in group of artifical semination with statistical significance (P < 0. 05 ). The rates of multiple pregnancy of 23.8% ( 160/671 ), 25.4% (104/410) ,21.1% (40/190) in subgroup of 1VF, ICSI and Thaw-ET were significantly higher than 10. 0% ( 27/269 ) in group of artifical insemination( P < 0. 05 ). The rate of macrosomia in group of in vitro fertilization was significantly lower than that of artificial insemination group (3.9% vs 8. 2%, P <0.05). However, the incidence of birth defect involved in various organs did not show significant difference between two groups ( P>0.05 ). Conclusions The incidence of multiple pregnancy demonstrated obviously increasing trends born with various In Vitro Fertilization techniques, which pave the way to high risk pregnancy. However, the incidence of newborn birth defect was not increased significantly. Thus, to lower occurrence of multiple pregnancy was the key approach to obtain neonates health.
