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.

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 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 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.

0. 05). When reperfusion time was prolonged, the level of NO in the experiment group was decreased gradually and was lower than that in control group (P

Objective To evaluate the safety of CT guided percutaneous lung biopsy in the elderly,and to analyze the risk factors for its complications.Methods Totally 204 elderly patients aged ≥65 years underwent transthoracic needle biopsy under CT guidance.Clinical data,complication and its risk factors were analyzed retrospectively.Results The complications included pneumothorax accounting for 15.2％ (31/204),hemoptysis 21.6％ (44/204),and no mortality was found.Logistic regression analysis showed that needle path ≥5.00 cm,lesion size ≤2.00 cm and emphysema around the lesion were the independent risk factors for postoperative pneumothorax (OR=4.05,2.54 and 3.97,all P＜0.05).Meanwhile,the enhancement degree by CT ＞40 HU,needle path ≥5.00 cm and lesion size ≤2.00 cm were the independent risk factors for postoperative bleeding (OR=2.27,2.82 and 2.33,all P＜0.05) in elderly patients undergoing lung biopsy.The sensitivity and specificity for postoperative pneumothorax and bleeding obtained by forecasting equation were 87.1％ and 49.1％,54.5％ and 80.8％ respectively.Conclusions The length of needle path,lesion size and emphysema around the lesion are correlated with pneumothroax,and length of needle path,lesion size and the CT enhancement degree are correlated with bleeding after percutaneous lung biopsy in the elderly.

Objective To investigate the relationship between the expression level of vascular endothelial growth factor (VEGF) and microvessel density (MVD) in placenta tissue and placenta increta.Methods Thirty singleton pregnant women who received antenatal care and underwent cesarean section in Fujian Maternity and Child Health Hospital between November 2013 and August 2014,were enrolled in this study.They were divided into placenta previa group,placenta increta group and control group,with ten patients in each group.Placenta tissue was collected from each patient.Expressions of VEGF and its mRNA were detected by immunohistochemistry,Western blot,and real-time polymerase chain reaction.MVD in placenta tissue was measured by immunohistochemistry.Rank sum test,t test,Kruskal Wallis test,one-way ANOVA and Spearman correlation test were used for statistical analysis.Results (1) Gestational age at admission and delivery in placenta previa and placenta increta groups was lower than in control group (all P＜0.05).Compared with control group,the placenta previa and placenta increta groups had more blood loss,and longer operating duration and hospital stay (all P＜0.05).(2) The expression levels of VEGF and its mRNA in placenta increta and placenta previa groups were higher than in control group (VEGF:0.691±0.032,0.695 ± 0.027 and 0.518±0.025,respectively,F=373.401;VEGF mRNA:1.667±0.661,1.832±0.678 and 0.767±0.269,respectively,F=27.399;both P＜0.05).But there was no significant difference between placenta previa and increta groups.(3) There was no significant difference of VEGF expression in increta location,border site and normal site in placenta increta group,but its mRNA was decreasing (2.519± 0.116,1.482 ± 0.232 and 1.000± 0.000,respectively,F=240.827,P＜0.05).(4) Expression level of VEGF at the attachment of umbilical cord,upper and lower margin of placenta in placenta previa group was higher than in control group (0.702 ± 0.026 vs 0.528± 0.020,t=12.302;0.698 ± 0.026 vs 0.519±0.035,t=12.715;and 0.685±0.029 vs 0.509±0.010,respectively,t=17.891;all P＜0.05).Expression of VEGF mRNA in placenta previa group was higher than in control group (2.080± 0.539 vs 1.024±0.272,t=8.093;1.587±0.757 vs 0.546±0.083,t=2.401;1.828±0.704 vs 0.731 ±0.157,t=4.259;all P＜0.05).(5) MVD in placenta increta group and placenta previa group was higher than in control group (171.2± 14.7,155.7± 14.6 vs 147.8±12.3,respectively,F=7.277,P＜0.05).(6) Expression level of VEGF in placenta increta group and control group was positively associated with MVD (r=0.825,P＜0.05).Conclusions There may be some common mechanisms in the occurrence of placenta previa and placenta increta.Overexpression of VEGF in placenta and abnormal formation of villous vessels may be important factors in the pathogenesis of placenta increta.
