Objective To evaluate early and mid-term results in infants,weighing less than 2 500 g,who underwent early cardiac surgery on cardiopulmonary bypass (CPB).Method Since November 2003 to December 2007,28 consecutive infants of less than 2 500 g underwent early cardiac surgery on CPB in Children's Hospital Affiliated to Fudan University.Sixteen infants were male,and 12 infants were female.The mean pregnancy period was 34 weeks (30 to 41 weeks) ,and 14 patients were premature,and the mean birth weight was 2 010 g(1 370-2 500 g).Mean age at operation was 27.46 d (range 1～61 d),and mean weight was 2 391 g (range 1 500～2 500 g).Deep hypothermia circulatory arrest was used in 9.Indications for surgery were:ventricular septal defect (10 infants),transposition of great arteries (6 iofants),totally anomalous pulmonary venom return (5 infants),pulmonary atresia with intact ventricular septum(2 infants),coarctation of aorta (1 infants) ,interrupted aortic arch (1 infants),cortriatriatum(1 infants),abnormal original of fight pulmonary artery (1 infants).Resuits Two (7.14%) infants died after operation at early phase.Mean duration of mechanical ventilation and intensive care unit stay were 113.9 h and 14.4 d,respectively.During follow-up (mean 16.87 months),one died.Two patients needed reintervention.About 84.4% infants didn' t need reintervention at the end of 12-month followup.Conclusions If medicine is aseless,infants woth low birth weight and congenital heart defect can obtain satisfactory outcome after CPB.Perioperative proration for virtual organs should be payed attention to.

Objective:To determine the function of miR-30b in the metastasis of colorectal cancer cells. Methods:RT-qPCR was performed to test miR-30b expression in 20 fresh primary colorectal cancer tissues and their corresponding adjacent tissues. Transwell and wound healing assays were performed to test the invasion and migration of colorectal cancer cells after miR-30b overexpression or inhibition. Bioinformatics assay was performed to predict miR-30b targets. Western Blot and Dual Luciferase reporter assay were per-formed to test the expressions of Snail and downstream target genes in colorectal cancer cells. Results:The results reveal that miR-30b expression decreased in cancer tissues compared with normal tissues. Transwell and wound healing assays reveal that miR-30b overex-pression inhibited cell invasion and migration, whereas miR-30b inhibition promoted the invasion and migration of colorectal cancer cells. Bioinformatics analyses reveal that miR-30b targets the 3'-UTR of Snail. Dual Luciferase reporter assay confirms that miR-30b af-fects the 3'-UTR of Snail. Western Blot analyses show that Snail and Vimentin expressions were significantly downregulated, whereas E-cadherin expression obviously increased after miR-30b overexpression. However, Snail and Vimentin expressions increased, but E-cadherin expression decreased after miR-30b inhibition. Conclusion:The miR-30b gene is downregulated in colorectal cancer tis-sues. The miR-30b protein may be important in the regulation of cell invasion and migration by targeting Snail in colorectal cancer cells.

Objective To compare the efficacy of inhaled Iloprost and nitric oxide( NO)in infants with moderate or severe pulmonary hypertension(PH)after congenital heart disease surgery. Methods This was a prospec-tive randomized study in Children's Hospital of Fudan University from January 2011 to January 2014,including 40 in-fants who suffered from moderate to severe PH after heart surgery. Their ages ranged from 1 to 24 months. Their weight ranged from 3. 2 to 11. 0 kg. They were randomly allocated to inhale NO( NO group,n = 20)or Iloprost( Iloprost group,n = 20). Iloprost group was given Iloprost with 50 ng/(kg·min)for 10 min and then combined with NO 20 × 10 - 6 for 10 min;NO group was first given 20 × 10 - 6 of NO for 10 min,then combined with Iloprost 50 ng/(kg·min) for 10 min. Heart rate,systolic blood pressure,pulmonary artery pressure(PAP)and central venous pressure were recor-ded continuously. At the same time,the concentration of nitrogen dioxide and methemoglobin after inhaling NO was de-tected. Results Inhaled Iloprost and NO caused significant reduction in PAP(t = 4. 670,P = 0. 009;t = 3. 762,P =0. 004)and pulmonary - to - systemic pressure ratio(Pp/ Ps)(t = 16. 974,P = 0. 000;t = 9. 682,P = 0. 000)but signifi-cant increase in oxygen index separately. The combination had no additional effect compared with single application. In term of the reduction of PAP,there was no significant difference between inhaled Iloprost and NO(F = 2. 742,P =0. 129). The levels of nitrogen dioxide and methemoglobin were not above the normal limits. Conclusions Moderate to severe PH after cardiac surgery was significantly reduced by inhaled NO and Iloprost. They had similar effects. However, the combination of both vasodilators failed to prove more potent than either substance alone. Compared with the potential toxicity of NO,the individual differences and the complex transmission,Iloprost may be more reasonable and feasible for the postoperative treatment of PH.

Objective The cardiac synchronization therapy (CRT) was proven to have good treatment for the cardiac conduction disorders patients with serious heart failure. But many disadvantages were gradually be noticed, such as difficulty of sinus electrode implantation, coronary sinus injury and bleeding, still one third CRT cases remain unchanged cardiac function.Recently the epicardial lead CRT therapy by the cardiac surgeons appears promising to provide better clinic resynchronization.The aim of this research is to explore the clinical value of surgical epicardial lead CRT for the cardiomyopathy heart failure with micro-invasive thoracoscopy techniques. Methods During April 2007 to Sep 2009 eleven patients were diagnosed as advanced heart failure with cardiac dysynchronization proven by the ECG and tissue Doppler echo examination. The dysynchronization parameters of tissue Doppler echo includes left ventricle maximize delay time , the left dysynchronization index (Ts-SD), the inter-ventricle mechanical delay time (IVMD), left ventricle end-dilation diameters (LVEDD) and the left ventricle ejection fraction (LVEF). All the patients got the consent agreement before the surgery. In the hybrid operation room the right atrial and ventricle endocardial electrodes were placed firs guided by X ray under the general anesthesia and double lumnen incubation. Then the thoracoscope techniques were used to explore the left ventricle lateral wall. The right atrial and ventricle electrodes were connected into the three chamber pacemaker. The Tissue Doppler Echo TEE technique was used to check which part of the left ventricle lateral wall is suitable for the idea CRT therapy. Usually the latest activated part of the left ventricle wall is the goal place. Then the epicardial electrode was fixed with 4-0 prolene suture at the idea place. All the cases were performed by the same surgeons group in the same medical center. The resynchronization features were examined after surgery and during the follow up. Results The endocardial and epicardial electrodes were implanted successfully without any serious complication. All patients were weaned and discharged without any adverse cardiac episodes. There is no mortality during the follow up period. All the patients received the β-blokers, diuretics, ACEI/ARB and other traditional medicine for the heart failure.The Tissue Doppler showed the E peak wave separated form the A peak which means the good resynchronization between the atrium and the ventricle. After surgery during the follow up the left ventricle maximize delay time decreased from (393.4 ±40.2 ) ms to ( 102.1 ± 34.6) ms, the left dysynchronization index (Ts-SD) decreased from (145.2±29.3)ms to(51.0±21.4) ms, the inter-ventricle mechanical delay time (IVMD) decreased from (59.1 ±23.4) ms to (31.2 ± 11.5 ) ms, left ventricle end-dilation diameters increased from (73.1 ± 13.4) mm to (63.2 ± 6.7) mn and the left ventricle ejection fraction increased from 0.32 ±0.04 to 0.41 ±0.07. Conclusion The micro-invasive surgical synchronization therapy could get good CRT result for the cardiomyopathy heart failure patients. Some patients traditionally in the waiting list for the heart transplant could be considered for the CRT therapy candidates.

Objective To investigate the role of outer membrane protein in clinical isolated car-bapenem resistance Acinetobacter baumannii. Methods Carbapenem resistance and sensitive strains were collected from the same patient. After MIST and REP-PCR analysis, carbapenemases were detected by isoe-lectric focusing. Different expressed membrane proteins were identified by two-dimension electrophoresis and mass spectrometry analysis. We also used efflux pump inhibitor PAβN(Phe-Arg-β-naphthylamide) to con-firm the phenotype. Results Carbapenem resistance and sensitive strains were attributed to the same pat-tern. At positions of P17.6 and P19.0, two β-lactamases were expressed in two investigated strains, no cabapenemases were detected. Six differential expressed membrane proteins were identified, a 34 × 10~3 membrane protein that was confirmed by efflux pump inhibitor PAβN experiment (imiponem MIC decreased from far above 32 μg/ml to 8μ/ml) and OprD and CarO. Conclusion Up-regulation of exported protein accompanied with down-regulation of OprD and CarO other than carbaponemases are responsible for carbap-enem resistance in A. baumannii.

Objective To observe and measure the anatomical structure of approach of vertical facial nerve canal and put forward the normal measurement range and the location relationship among the vertical segment of facial nerve canal, the posterior wall of external acoustic meatus and the rear edge of external ear,and discuss the relationship and clinical significance between the mastoid gasification and the vertical segment of facial nerve canal. Methods 1. Evaluate the accuracy of CT image of related structure, using spiral CT in scanning four skull specimens, get the horizontal distances of the vertical segment of facial nerve canal to the posterior wall of external acoustic meatus and the rear edge of external in the axial position, and get the sagittal diameter of mastoid (the horizontal distance from the lowest point of external auditory inferior canal to the rear edge of mastoid) and the height (the vertical distance between the lowest points of the external auditory canal wall to the mastoid tip) in the sagittal position. And then saw the skull specimens to measure the distance in the same lay with CT image, and discuss the statistics difference of the distance between the values of CT imaging measurements and the dry entities cranial measurements on hand. 2. Study on people: 118 patients (236 sides) with non-ear disorders were randomly selected, among which there were 63 females (126 sides) and 55 males (110 sides). They were subjected to maxillofacial CT scan in the same layer that used above, and the horizontal distances of the facial nerve canal to the posterior wall of external acoustic meatus and the rear edge of external ear were measured. In addition, half of the product of diameter and height of the mastoid was defined as mastoid area, which was used to define the extension of mastoid gasification. Then related analysis and regression analysis were done between the vertical segment of facial nerve canal and the posterior wall of external acoustic meatus, as well as the rear edge of external ear. Results 1.Part of the experiment: There was no significantly different on the indicator values between CT image the entity measurements among the four skull specimens (P>0.05). 2. Study on people: There was no significantly different between left side and right side(P>0.05), but significantly different between genders(P<0.05). Between mastoid area and the distance from the vertical segment of facial nerve canal to the posterior wall of external acoustic meatus there is inverse correlation, and the relevance has the remarkable significance. However, there was no correlation between mastoid area and the vertical segment of facial nerve canal to the rear edge of external ear. Conclusion There was some relationship between the location of the vertical segment of facial nerve canal and external acoustic meatus. Anatomic position of vertical facial nerve cancal and the posterior wall of external acoustic meatus can be showed clearly. CT and in combination with primitive axial images may provide reliable evidence for the diagnosis facial nerve dieases and the choice of ear surgery route.
