Congenital cardiovascular anomalies are present in approximately 80％ of children with 22q11.2 deletion syndrome.Three genes in chromosome 22q11.2 ( TBX1,CRKL,and ERK2 ) have been identified whose haploinsufficiency causes anomalies of 22q11.2 deletion.The most common diseases are conotruncal anomalies,which include tetralogy of Fallot ( TOF),pulmonary atresia with ventricular septum defect (PA-VSD),truncus arteriosus,and interrupted aortic arch.In major phenotypes,a high prevalence of the deletion is noted in patients with TOF with pulmonary atresia,TOF associated with pulmonary atresia and major aortopumonary collateral arteries,persistent truncus arteriosus,and type B interruption of aortic arch.In minor phenotypes,right aortic arch,aberrant subclavian artery,and major aortopulmonary collateral arteries are frequently associated with cardiovascular anomalies associated with 22q11.2 deletion.In conclusion,conotruncal anomaly associated with aortic arch and branch anomalies should increase the suspicion of 22q11.2 deletion.

creased maternal serum adiponectin level may be involved in the pathogenesis of pre-eclampsia and also may contribute to the reduced expression of adiponectin in the omental adipose tissue.

Objective To investigate the effects of T-2 toxin on testosterone biosynthesis in primary cultured Leydig cell derived from the mouse testis.Methods Leydig cells isolated from Kunming male mice were adjusted to 5?105/ml and the purity was identified by the modified 3?-hydroxysteroid dehydrogenase(HSD) staining method.Blank control group(treated with 0 ng/ml hCG and 0 mol/L T-2 toxin),inductive control group(treated with 10 ng/ml hCG and 0 mol/L T-2 toxin),low dose T-2 toxin exposure group(treated with 10 ng/ml hCG and 10-9 mol/L T-2 toxin),middle dose T-2 toxin exposure group(treated with 10 ng/ml hCG and 10-8 mol/L T-2 toxin) and high dose T-2 toxin exposure group(treated with 10 ng/ml hCG and 10-7 mol/L T-2 toxin) were designed,respectively.The testosterone level was measured after 24 h of incubation.Results After 24 hours culture in liquid medium contained serum,the fresh isolated Leydig cells grew well and the purity exceeded 90%.Through 10 ng/ml hCG induce,the testosterone level of Legdig cells increased significantly and the difference compared to blank control was of statistical sense(P

Objective To explore the effect of transcranial magnetic stimulation (TMS) on gross motor function for children with cerebralpalsy. Methods 80 children with cerebral palsy treated in our hospital during July 2009 to January 2010 were divided into control group(n=40) and observation group (n=40). The control group received conventional treatment, including physical therapy, massage, scalp acupuncture,body acupuncture, point injection, physiotherapy and medication. The observation group received TMS in addition. The therapeuticeffects were compared using the Gross Motor Function Measure-88 (GMFM-88) after 3 months. Results The percent scores of all the domainssignificantly increased in both groups (P<0.05) after treatment, the increased percent scores of observation group in B domain, D domain,E domain and total were higher in the observation group than in the control group (P<0.05). Conclusion TMS can further improve thegross motor function of children with cerebral palsy.

Objective To investigate the inhibitory effect of siRNA targeting casein kinase 2 (CK2α)gene on the growth of HCT1 1 6 cells and to clarify its mechanism.Methods CK2α-siRNA sequence was designed according to mRNA sequence of CK2α. The in vitro cultured HCT1 1 6 cells were divided into normal control group (without transfection),negative control group (transfected with siRNA)and CK2α-siRNA group (transfected with CK2α-siRNA ),and the HCT116 cells were transfected with Lipofectamine 2000.The expression levels of CK2α,cyclin H,P53,and P21 proteins in the HCT116 cells were detected by Western blottting method,and the proliferation activities of the HCT116 cells were detected by MTT method,and the cell cycle was measured by flow cytometry. Results Compared with negative control group,the expression levels of CK2α,and cyclin H proteins in CK2α-siRNA group were decreased(P<0.01);the expression level of P53 protein had no change dramatically(P>0.05), and the expression level of P21 protein was increased significantly(P<0.01).Compared with negative control group,the survival rate in CK2α-siRNA group was decreased markedly 48 and 72 h after transfection detected by MTT method(P<0.01).Flow cytometry analysis showed the percent of the cells at G1 phase in CK2α-siRNA group was significantly higher than that in negative control group and the percent of the cells at S phase in CK2α-siRNA group was lower than that in negative control group(P<0.01),and the cell cycle was arrested at G1 phase. Conclusion siRNA targeting CK2αcan inhibit the proliferation of HCT116 cells and induce the arrest of G1 phase, which may be associated with inhibiting the expression of cyclin H and recovering the P53 activity after silencing CK2α.

Objective: To explore the association of fetal umbilical artery (UA) Doppler blood flow parameters with umbilical vein (UV) serum sEng,nitric oxide (NO) level and the perinatal outcome in patients with preeclampsia(PE). Methods: Color ultrasonography was used to detect the resistive index (RI), pulse index (PI), the peak systolic velocity (Vs), diastolic velocity (Vd) and the peak-systolic/diastolic ratio(S/D) of UA in 39 PE patients(20 cases of mild preeclampsia, 19 cases of severe preeclampsia), 20 cases of normal full-term pregnant women and 20 gestational hypertension(GH) women. The UV serum level of sEng was analyzed using enzyme-linked immunosorbent assay (ELISA). The level of NO was determined using nitric acid recovery, and to analysis of perinatal outcome. Results: Compared with normal pregnancy and GH, levels of S/D, RI, PI and sEng were significantly higher in the mild and severe preeclampsia group(P < 0.05), and levels of Vs, Vd and NO were significantly lower(P < 0.05). There was a negative correlation between the values of PI, RI and S/D with the level of UV serum NO in the mild and severe preeclampsia group(P < 0.05). There was a positive correlation between the values of PI, RI and S/D with the level of UV serum sEng in the mild and severe PE group (P < 0.05). The incidence of perinatal disease was significantly higher in PE (P < 0.05). Compared with normal perinatal infants, the abnormal perinatal infants had obviously higher levels of S/D, RI, PI and sEng (P < 0.05), and lower levels of Vs, Vd and NO(P < 0.05) in PE. Conclusion: The umbilical artery blood flow parameters can reflect the disease condition and fetal status, which has an important clinical value.

Objective With the social and economic advancement, the morbidity of breast hypertrophy is increasing. Inverted T technique was the traditional breast reduction mammaplasty method. It left severe scar after operation. The aim of this study was to introduce our experience about breast reduction with pure liposuction that significantly reduced the operative scar after operation. Methods After using tumescent anesthesia, a small incision about 5 mm was performed at inframammary fold for proper selected patients, The entire breast and subcutaneous fat were thoroughly suctioned with small caliber cannulas for breast reduction. No surgical excision was applied. Compression garment was applied after the operation. Results A total of 11 patients were successfully treated. Only one patient had a unilateral seroma that was responded to multiple aspiration. All the patients were satisfied with the results. The morphology was good. The texture of the breast was improved. Conclusion Reduction mammaplasty with pure liposuction is simple and effective for those who had mild to moderate breast hypertrophy with no severe ptosis and more fatty tissue. The scar is invisible. It deserves to be recommended.

Objective To evaluate the effect of the activity of Ca2+/CaN-NFATc on the activation and prolfferation of lymphocyte in asthmatic rats.Methods The rats of the asthma group and the CsA group were sensitized and challenged by ovalbumin.So did the control group with saline instead.Lymphocyte was separated from spleen and cultured for 24 hours,and PHA-p (5 μg/ml) was added to the culture medium in every group,CsA ( 1.0 μg/ml) was added to the CsA group,respectively.The concentration of [ Ca2+ ] i,the activity of CaN,the protein expression of dephosphorylated NFATc and Cyclin E in T lymphocyte were assayed.The level of IL-4 and IL-2 in culture supernatants was measured,and the cell cycle distribution of lymphocyte was analyzed.ResultsWhen compared to the control group,the activity of Ca2+/CaN-NFATc [ (81.21 4-14.39) vs (63.66 ±9.02) ] was increased and the protein expression of CyclinE [ (0.9327 ±0.0370) vs (0.8374 ±0.0637) ] was higher in Lymphocyte of the asthma group ( P＜0.05,P ＜0.01,respectively).The percentage of lymphocyte in the S phase [ (7.8600±2.8241) vs (4.0270 ± 1.8650) ] and S + G2/M phase [ ( 10.6700±3.3850) vs (5.8740 ± 1.4389) ] was higher;however,the percentage of G0/G1 phase [ (89.3300 ± 3.3850) vs (94.1260± 1.4389 )] was lower in asthma group ( all P ＜ 0.01 ).The level of IL-4 [ ( 1.55 ± 0.19) pg/ml vs (0.99 ± 0.12 ) pg/ml ] and the IL-4/ IL-2 ratio [ (0.81 ±0.12) vs (0.49 ±0.49) ] in culture supernatants of the asthma group were higher than those of the control group ( all P ＜0.01 ).While the activity of Ca2+/CaN-NFATc (47.19 ±7.16)was decreased and the protein expression of Cyclin E (0.6840 ± 0.0485 ) was reduced in lymphocyte in CsA group(all P ＜0.01 ),the percentage of lymphocyte in the S phase (4.8600 ± 1.9595) and S + G2/M phase (7.9900 ± 1.9405) was decreased and the percentage of G0/G1 phase (92.2100 ± 1.9267) was increased ( all P ＜ 0.05 ),and the level of IL-4 (0.47 ± 0.09 ) pg/ml and the ratio of IL-4/ IL-2 (0.78 ±0.20) was lower in culture supernatants in the CsA group than that of the asthma group( all P ＜ 0.01 ).There was a positive correlation between the protein expression of dephosphorylated NFATc and the protein expression of CyclinE in Lymphocyte,so did between the protein expression of NFATc and the level of IL-4 in culture supernatants( r =0.711,P ＜0.01 and r =0.749,P ＜0.01.respectively).Conclusions The activity of Ca2+/CaN-NFATc was increased in lymphocyte of the asthmatic rats.Its increasing might result in the imbalance of Th1/Th2 by promoting the expression of IL-4 and might lead to the proliferation of lymphocyte by promoting the Cyclin E expression.
