Not only calmodulin (CAM) with Ca2+ regulates the activity of many enzymes and proteins, but also free-CaM (no Ca2+bound) and Ca2+-independent CaM-binding proteins play roles in plant and animal cells. There is no in vivo method to identify the interaction between free-CaM and Ca2+-independent CaM-binding protein (CaMBP). Using site-directed mutagenesis by polymerase chain reaction (PCR), 5 mutant Arabidopsis calmodulin isoform 2 (AtCaM2) genes, mCaM21, mCoM212,mCaM2123, mCaM2124 and mCaM21234 were obtained. The mutant mCaM2 encoded glutamine in place of glutamate (E32Q; E68Q; E105Q; E141Q) in one or more EF-hand Ca2+-binding motifs of AtCaM2. The recombinant mCaM2 proteins were produced in Escherichia coli, and subsequently separated on SDS-PAGE in the presence of Ca2+ or EGTA, their electrophoresis mobilities were related with that of mutant EF-hand motifs. 45Ca2+ overlay analysis indicated that the more glutamate replaced by glutamine, the lower affinity with Ca2+ in the mCaM2 proteins. The mCaM21234 mutant protein (E32Q; E68Q; E105Q;E141Q) was unable to bind Ca2+. Using yeast two-hybrid technique with mCaM21234 as bait, it was possible to see interaction in Arabidopsis of AtCaM2 with IQD26, a calcium-independent CaM-binding protein. Site-directed mutation of AtCaM2 will aid the research of Ca2+, CaM and Ca2+-independent CaMBPs in plant biological processes.

Objective To observe the effect of Guanxin Ⅱ Hao on plasma NO and NOS in dog with myocardial ischemia. Methods 20 dogs of myocardial ischemia were divided into the control group, isosorbidi mononitratis group and the Guanxin Ⅱ Hao group by random. The NO and NOS of serum were measured, before and after treatment. Results In the control group, the level of NO and NOS were higher than that of the isosorbide mononitrate group. There was significant difference between the control group and the Guanxin II Hao groups (P

Objective To study the expression and significance of vascular endothelial growth factor(VEGF) in serum of umbilical blood from the newborns of women with severe pre-eclampsia.Methods Radioimmunoassay was used to measure the serum VEGF of umbilical blood from 26 newborns of women with severe pre-eclampsia (severe pre-eclmpsia group) and 30 newborns of normal pregnancy women (control group). According to birth weight-gestational age relation,severe pre-eclampsia group included 15 newborns small for gestational age (SGA group) and 11 newborns appropriate for gestational age (AGA group).Results (1)The VEGF level of umbilical vein blood and umbilical artery blood in severe pre-eclmpsia group was significantly higher than that in control group respectively(t = 2.16, P < 0.05;t = 4.82, P < 0.01). (2) In control group and severe pre-eclampsia group, the VEGF level in umbilical artery blood was significantly higher than that in umbilical vein blood (control group: t = 2.24, P < 0.05;severe pre-eclampsia group: t = 3.00, P < 0.01). (3)In both control group and severe pre-eclampsia group, there was no significant correlation respectively between VEGF levels in umbilical vein blood or umbilical artery blood and newborns' gestational age or birth weight. (4)VEGF level of umbilical artery blood in SGA group was significantly higher than that in AGA group as well as in control group(t = 3.22, P < 0.01 ;t = 6.80, P < 0.01). Conclusions The serum VEGF level of umbilical vein blood and umbilical artery blood from the newborns of women with severe pre-eclampsia was significantly higher than that of normal pregnancy women respectively. The VEGF level of umbilical artery blood can reflect the severity degree of the damage of hypertensive disorder complicating pregnancy to their newborns to some degree.

To investigate the effect of propofol on the plasma contents of endothelin(ET) and calcitonin gene related peptide(CGRP).Twelve monkeys with hemorrhagic shock were divided randomly into two groups.The monkeys in propofol group(PG) were administered propofol to 8mg/L plasma concentration by target control infusion with computer,while monkeys in control group(CG) were not .Venous blood were collected to determine plasma ET and CGRP contents by radioimmunoassay before bleeding, 2 hours after hemorrhagic shock and 2h after resuscitation. Compared with control group,the CGRP level and CGRP/ET of PG were significantly increased at 2h after hemorrhagic shock and 2h after resuscitation,while ET level of PG at 2h after resuscitation was significantly lower than that of CG. These findings indicate that propofol can increase the plasma content of CGRP and decrease the plasma content of ET in monkeys after hemorrhagic shock and resuscitation, and ET may play an important role in the development of hemorrhagic shock.

It is very important to have a clear and widely accepted definition and classification for clinical diagnosis, rehabilitation, research and social support of children with cerebral palsy, as well as in establishing a regional, national and global monitoring database. There are some new changes about the definition, clinical types and function classification of cerebral palsy recently domestic and abroad, which pay more attention to assessments on function and participation in daily life.

Objective To explore the distribution and correlation of gross motor function and manual ability in 4～12 year old children with cerebral palsy of different types. Methods 143 children with cerebral palsy (CP) were recruited according to the inclusion and exclusion criterions. They were assessed with Chinese version of Gross Motor Function Classification System （GMFCS） and Manual Ability Classification System （MACS）. Results The classification of GMFCS and MACS was Ⅰ～Ⅱ in 33 (60.0%) children with spastic diplegia; Ⅲ～Ⅴ in 28 (75.7%) children with spastic quadriplegia; Ⅰ in 21 (55.3%) children with spastic hemiplegia, and GMFCS Ⅱ in 2 children, MACS Ⅱ in 14 children. There was moderate correlation between GMFCS and MACS （r=0.67，P<0.05）. Conclusion GMFCS and MACS can be used to determine the gross motor function and manual ability in CP children of different types.

In Europe Registration Management for Cerebral Palsy (CP) has been widely carried out, which collects various related information and systematically manages the rehabilitation of children with CP by uniform database. Chinese Registration Management for Cerebral Palsy fitted with Chinese situations should be established as soon as possible which will benefit the following: to provide more samples for scientific research on cerebral palsy; to promote social awareness and attention for CP children by multiple side participation; to help policymaker to plan more suitable policies for CP children and their families. The main problems needed to resolve are unification of the diagnosis, clinical types and function classification of cerebral palsy.

Objective To investigate the effects of commonly used inductive agents on peripheral blood monocytic myeloid-derived suppressor cells (M-MDSCs) in renal transplantation recipients and to discuss their possible mechanism.Methods The enrolled patients received rabbit anti-thymocyte globulin (rATG) or basiliximab for induction therapy,with the maintenance immunosuppressive regimen of tacrolimus,mycophenolate mofetil and steroid.The number of CD11 b + CD33 + HLA-DR-CD14 + CD1 5-M-MDSCs and cytokine levels in peripheral blood,including interferon-γ(IFN-γ),interleukin-2 (IL-2),IL-4 and IL-6,were measured by flow cytometry before and 1 week,2 weeks,1 month,2 months,3 months after operation.Results A total of 47 recipients (29 given rATG 29,and 18 given basiliximab) were included in this study.Compared to the patients with basiliximab,asignificant increase in the frequency of M-MDSCs was observed in the rATG group at 2nd month after operation (5.5％ ± 2.8％ vs.3.8％ ± 1.6％,P＜0.001) and at 3rd month after operation (7.0 ％ ± 3.1％vs.4.1％ ± 2.3 ％,P＜ 0.001),while there was no significant difference in the cell number between the two groups.In the cytokine detection,levels of IL-2 and IL-4 in the rATG-treated recipients were significantly higher at 2nd weekpostoperation (Pr2 =0.032,and PIL-4 =0.019)and 1st month postoperation (PIL-2 =0.024,PIL-4 ＜0.001) than the basiliximab group.Conclusions ATG promotes the expansion of M-MDSCs,which is associated with the secretion of IL-2 and IL-4 due to the lymphocytes depletion.The synergistic immunosuppressive effect may contribute to the induction of immune tolerance.

Objective:To investigate the effect of basic fibroblast growth factor(bFGF) on the proliferation of gingiva-derived mesenchymal stem cells(GMSCs) in vitro.Methods:GMSCs were isolated from healthy gingival tissue samples and identified.GMSCs of passage 4 were treated by bFGF at 0,0.5,1,5,10,20 ng/ml respectively for 1-9 d.The proliferation of the cells was evaluated using CCK-8 kit.Results:bFGF at 0.5-20 ng/ml increased GMSCs proliferation.0.5-10 ng/ml of bFGF showed dose and time dependant proliferation promoting effect on GMSCs.Conclusion:bFGF can increase GMSCs proliferation ability in a dose and time dependant manner.
