ObjectiveTo establish a analytical system for the survival motor neuron (SMN) subtle mutation,and evaluate its application in two families with spinal muscular atrophy (SMA).MethodsSMN genes in seven family members from two SMA families were analyzed at both transcript level and genomic level,by the use of the conventional PCR-RFLP,allele-specific PCR,multiplex ligation-dependent probe amplification (MLPA) and T subcloning and sequencing of SMNI gene.ResultsIn family A,the patient had a single SMN1 copy who was carrying nonsense mutation L228X,which was also found in his father.In family B,as the patient's sample was unavailable,the father was indeed a carrier with one normal SMN1 allele and the other SMN1 allele carrying a frameshift mutation 22_23insA.The remaining family members were SMA carriers with one SMN1 copy.ConclusionThis analytical system for SMN subtle mutation offers viable molecular basis for genetic counseling and prenatal diagnosis in SMA families.

Objective To assess the left ventricular(LV) regional myocardial systolic function after bone marrow mesenchymal stem cells (BMSCs) injection in rabbits with acute myocardial infarction(AMI) by 2-dimensional ultrasound speckle-tracking imaging.Methods Twenty-four healthy rabbits were randomly divided into three groups:group of sham-operated,group of masculine control (AMI was induced by ligation of left anterior descending coronary artery),and group of cell infusion(after two weeks of AMI,bone marrow mesenchymal stem cells were injected to the region of AMI).Four weeks after cell deliver two-dimensional strain images were acquired from LV short-axis view(at the levels of mitral annulus,muscle papillary and apex),radial strain rate (SrR),circumference strain rate (SrC),rotation rate (RotR) and rotation (Rot) of three levels in short-axis views were measured by speckle-tracking imaging.The conventional echocardiography indices included LV diameter of end diastole(LVEDd),LV ejection fraction(LVEF),LV fractional shortening(LVFS).The catheter indices included LV systolic pressure(LVSP),LV end diastolic pressure (LVEDP)and maximum rate of rise and descend of LV pressure(LVdp/dtmax).ResultsCompared with sham-operated group,rabbits had significantly larger LVEDd,lower LVEF and LVFS,lower LVSP and LVdp/dtmax,higher LVEDP in control group,SrR,SrC,RotR and Rot of LV anterior regional myocardial function and global myocardial function of three levels in short-axis views were lower.Compared with control group,the rabbits had significantly smaller LVEDd,larger LVEF and LVFS,larger LVSP and LVdp/dtmax,lower LVEDP,SrR,SrC,RotR and Rot of LV anterior regional myocardial function and global myocardial function of three levels in short-axis views were larger in group of cell infusion.There was no significant between group of cell infusion and group of sham-operated.Conclusions Speckle tracking imaging can evaluate the regional myocardial systolic function of the area of BMSCs transplantation accurately.

Objective To explore the long-term efficacy of botulinum toxin type A injections on facial beauty and its long-term safety.Methods A total of 33 beauty-seekers with botulinum toxin type A treatment for more than five years were reviewed as observation group,using digital muscle palpation meter (Myoton PRO) for the determination of the orbicularis oculi muscle and masseter muscle tension (F),the muscle characteristic parameters,such as muscle hardness (S) using a homemade facial questionnaire test for satisfactory rate of beauty from both beauty-seekers and physicians.At sametime,33 normal adults that never accepted botulinum toxin injection with matched age and gender were collected as control group.The same-sex indicators were dtermined and compared with using statistic analysis t test.Results The pairwised parameters of the same sex and site were comparied between the two groups;average F and S values in the observation group were lower than those of the control group,but no statistically significant difference were observed between the two groups (P＞0.05);in the observation group,average appearance age was 7.3 years younger than the control group,and the facial shape improved significantly.Conclusions Long-term and repeated application of botulinum toxin A is able to remove crow's feet and decrease the masseter and so the injection is safe with high satisfaction to beauty-seekers.

Objective To study the clinical experience of extracorporeal circulation management in modified total arch replacement combined with stented elephant trunk.Methods Fifty-eight patients with Stanford A aortic dissection underwent modified total arch replacement combined with stented elephant trunk.With the modified surgical technique,the technology of extracorporeal circulation was also modified with bilateral antegrade cerebral perfusion,the management of the temperature and blood protection.Results All patients were operated successfully.The operative time was 248-485 (396 ± 67) min,extracorporeal circulation time was 175-260 (181 ± 33) min,cross clamp time was 64-104 (85 ± 12) min,stop circulation time was 22-48 (32 ± 5) min,and selective cerebral perfusion time was 26-54 (39 ± 7) min.The ventilator assisted breathing time was 5.0-35.5 (23.0 ± 4.5) h,and ICU monitoring time was 24-140 (88 ± 12) h.Postoperative complications included transient neurologic deficit in 3 cases (5.2％,3/58),renal dysfunction in 5 case (8.6％,5/58),and pulmonary infection in 4 cases (6.9％,4/58).Conclusion To modified total arch replacement combined with stented elephant trunk,the modified management of extracorporeal circulation with bilateral antegrade cerebral perfusion,the management of temperature and blood protection,has a low prevalence of morbidity and mortality.

Objective To analyze the clinical significance and features of patient s' with inconsistent antineutrophil cytoplasmic antibodies (ANCA) test results between indirect immune fluorescence (IIF) and enzyme-linked immunosorbent assay (ELISA).Methods ANCA were detected with IIF and ELISA method jointly among 12 386 in-patients and a retrospective analysis on the proportion of clinical features and significance was made in 589 cases with inconsistent results using Microsoft Excel 2007 statistical software.Results Among the 589 patients,68 (11.5％) were diagnosed as vasculitis,in which 51 cases as ANCA-associated vasculitis,and 521(88.4％) were diagnosed as non-vasculitis including 181 connective disease and 340 non-connective diseases in which hypertension and cardiopathy were common.The common inconsistent results of ANCA were p-ANCA/ELISA (-),IIF (-)/anti-MPO (+),IIF (-)/anti-PR3 (+),IIF (-)/anti-PR3 (+) anti-MPO (+) accounted for 24.4％ (144/589),29.5％ (174/589),15.9％ (94/589),18.5％ (108/589) respectively,these accounted for 88.3％(520/589) of total inconsistency.Conclusion The spectrum of diseases and clinical characteristics varies widely and often presents with multiorgan involvement in patients with inconsistent ANCA results.These reasons make it easy to be misdiagnosed.Attention should be paid to identify and different these inconsistency.

Objective To compare the MRI features of hepatic neuroendocrine tumors (NET G1,G2) and neuroendocrine carcinomas (NEC G3),as well as to improve the accuracy in hierarchical diagnosis.Methods Twenty patients with histopathologically proven NET and nineteen patients with histopathologically proven NEC were retrospectively analyzed.The morphological and MR signal features were compared.Results The morphological features of vascular invasion (P ＜ 0.05) and lymphadenectasis or necrosis (P ＜ 0.05),as well as the MR signal features on portal phase (P ＜ 0.05) and delayed phase (P ＜0.05) were different between the NET group and the NEC group;contrast to noise ratios (CNR) were also different between the two groups (x2 =5.14,P ＜ 0.05),CNR of the NEC group on both arterial phase (Z =121.75,P ＜ 0.05) and portal phase (Z =139.31,P ＜ 0.05) were significantly lower than the NET group;ROC analysis of CNR demonstrated an area under the curve of 0.729 (P ＜ 0.05) on portal phase,when the optimal cut-off value of-61.38 was used,a sensitivity of 90.0％ and a specificity of 63.2％ can be achieved.Conclusions MRI plays an important role in the hierarchical diagnosis of hepatic neuroendocrine neoplasms.The signs of vascular invasion,lymphadenectasis or necrosis as well as the MR signal features during dynamic enhanced scanning are of great value in differentiating NETs from NECs.
