ObjectiveTo observe the change of cardiac function after acute myocardial infarction (AMI) in rabbit model,and to study MRI characteristics of left ventricular remodeling (LVR).Methods Forty-five japanese white rabbits underwent chest-opening coronary artery ligation surgery to obtain rabbit myocardial infarction model The animals were scanned on a 1.5 T MR scanner ( GE Healthcare,Chalfont St.Giles,UK) at six time-points as surgery,1,2,4,6,8 weeks after surgery. Cardiac function parameters were measured,including left ventricular end diastolic volume ( EDV ),stroke volume ( SV ),ejection fraction (EF),peak ejection rate ( PER ) and peak firing rate (PFR).At each time point,5 rabbits were randomly selected and performed re-thoracotomy to obtain heart specimen.Each specimen was examined by MRI with the diffusion tensor imaging ( DTI ).The value of ADC and fractional anisotropy (FA) were collected. Cardiac function data sets of different time points were analyzed using repeated measures data of ANOVA.The FA and ADC values of infarction myocardium set of different time points or different parts of the myocardium were analyzed using one-way ANOVA. The average was compared statistically between two adjacent groups using LSD-t test. Results Left ventricular EDV increased in progress with the time.It was increased from ( 2.21 ± 0.35 ) ml preoperatively to ( 3.15 ± 0.57 ) ml 8-week postoperatively.But the difference was not statistical significant ( F =1.384,P =0.220).EF was decreased from(57.31 ± 11.11 )％ to( 34.71 ± 8.72 )％.It dropped significantly and the difference was statistically significant (F =27.134,P =0.001 ).EF showed a downward trend with the increase of EDV.By linear regression analysis,an equation was set up with y =- 5.58x + 57.7 ( F =8.855,P =0.005 ).On the other hand,PER showed a progressive decline from (27.31 ± 13.06) ml/s to ( 17.31 ± 6.41 ) ml/s ( F =2.105,P =0.037 ),and PFR decreased from ( 23.79 ± 14.15 ) ml/s to ( 12.07 ± 6.91 ) ml/s ( F =2.366,P =0.011 ).FA value decreased from 0.442 ±0.093 to 0.107 ±0.037( F =12.61,P =0.001 ),and ADC valueshowed upward trend from (5.07 ± 1.15) ×10-4 mm2/s to(6.39 ±0.78) ×10-4 mm2/s (F=4.166,P =0.022 ).FA values of infarct,adjacent and remote region were 0.201 ± 0.049,0.316 ± 0.127 and 0.323 ± 0.117 respectively( F =3.896,P =0.004 ),and the ADC values in these regions were (6.19 ± 1.78 ) ×10 -4,(5.44 ± 2.63 ) × 1 0 -4,(5.29 ± 2.02 ) × 10 -4 mm2/s respectively ( F =3.248,P =0.018 ).FA and ADC values were significantly different between the infarct region and adjacent region ( t =7.327,P =0.001 ;t =3.292,P =0.005,respectively),but there was no significantly different between adjacent region and remote region ( t =1.024,P =0.129 ; t =1.467,P =0.164,respectively ).ConclusionsMRI measurement of parameters of cardiac function can be used to monitor the process of left ventricular function remodeling after AMI.The process of micro-structural remodeling of myocardium can be reflected by DTI.MRI provides a feasible imaging modality for LVR after AMI.

Objective To evaluate the effectiveness and safety of open tension-free hernioplasty and two kind of laparoscopic hernia repair for the treatment of primary unilateral inguinal hernia. Methods Patients suffering from primary unilateral inguinal hernia were randomly divided into 3 groups to undergoopen operation with mesh-plug and patch or transabdominal preperitoneal hernioplasty (TAPP) or totally extraperitoneal hernioplasty (ZEP). Results From February 2006 to February 2009, a total of 164patients were divided into 3 groups, with 62 undergoing open tension-free mesh-plug hernia repair, 50receiving TAPP and 52 receiving TEP. Postoperative patients were then followed up for a period of(16±8)months. The average operating time for the patients in the open mesh repair group was significantly shorter compared to the other two groups (P＜0.01 ). The cost in the open mesh repair group was also significantly lower than the other two groups (P＜0.01). The pain scores in open mesh group were significantly higher than those in the other two groups (P＜0.01). The hospital stay and the recovery time were both significantly longer in the open mesh repair group (P＜0.01) compared to the other two groups. No major complications and recurrence was found in neither groups. Conclusions Open tension-free mesh-plug hernia repair, TAPP and TEP are all safe and effective for the treatment for patients with primary unilateral inguinal hernia. TAPP and TEP are superior to open tension-free mesh-plug hernia repair as these two procedures involve less postoperative pain and fast recovery.

Objective To investigate the clinical characteristics and strategies of early stage antibody-mediated rejection after renal transplantation.Method The clinical data of early stage AMR of 3 cases of renal transplantation,and 1 case of pancreas transplantation after renal transplantation were retrospectively analyzed.(1) The case 1 was diagnosed as having early severe acute AMR.Serum creatinine was increased,urine volume rapidly reduced,the blood flow of transplanted kidney reduced on the postoperative day 8;the positive rate of panel reactive antibody (PRA) class Ⅰ and Ⅱ was 74.6％,and 2.7％ respectively on the postoperative day 12.Biopsy showed widely ischemia and local bleeding in transplanted kidney and DSA showed anti-B62 mean fluorescence intensity (MFI) increased to 6800 on the postoperative day 14.(2) The case 2 was diagnosed as having early mild acute AMR.The positive rate of PRA class [and Ⅱ was 65.6％ and 78.9％ respectively.DSA Ⅰ was positive,anti A11 MFI was 3059,and DSA Ⅱ was negative on the postoperative day 13.Biopsy showed mild ischemia reperfusion injury in transplanted kidney on the postoperative day 21.(3) The case 3 was diagnosed as having early severe chronic AMR,and the recipient received pancreas transplantation 1 year after kidney transplantation.Eight months after pancreas transplantation,DSA for pancreas donor was detectable,anti A2 MFI was 7514,anti B46 MFI was 3 159 and anti DQ7 MFI was 1 503.(4) The case 4 was diagnosed as having early mixed rejection.Serum creatinine was elevated on the postoperative day 8;PRA testing showed that the positive rate of class Ⅰ and Ⅱ was 3％ and 70％ respectively,DSA was positive,and anti DR16 MFI was 15 170 on the postoperative day 14;transplanted kidney biopsy showed acute mixed rejection on the postoperative day 16.Result Case 1 and case 3 were not diagnosed and treated in time and graft loss developed.Case 2 and case 4 were functionally recovered after combined treatment of plasmapheresis,IVIG and bortezomib.Conclusion Diagnosis of antibody-mediated rejection is based on transplant graft dysfunction,positive DSA and graft biopsy.Early diagnosis,early treatment and combined therapy can improve the curative rate of AMR.

Objective To study the clinical value and the safety of endoscopic retrograde cholangio-pancreatography(ERCP)for chronic pancreatitis in the pediatric population.Methods Clinical data,endo-scopic reports,and radiography of chronic pancreatic patients aged from 2 to 17 years old who underwent ERCP between Jan.1,2008 and Apr.30,2014 at Endoscopy Center of Ruijin Hospital were reviewed.These patients were divided into 3 groups,patients aged from 2 to 6 years old as children group(n =27),patients aged from 7 to 12 years old as juvenile group(n =35)and patients aged from 13 to 17 as adolescent group(n =25). Their clinical data and complications were analyzed by groups.Results A total of 170 ERCP procedures were performed in 87 patients,with the success rate of 99.4%(169 /170).All patients were diagnosed as having chronic pancreatitis by ERCP.Success rates of children group,juvenile group and adolescent group were 97.6%(40 /41),100.0%(72 /72)and 100.0%(57 /57)respectively.There was no statistically significance among the three groups(P =0.207).No serious complications like bleeding or perforation occurred.No proce-dure-related mortality occurred in this study either.The rate of post-ERCP adverse events in children group, juvenile group and adolescent group were 41.5%(17 /41),25.0%(18 /72)and 24.6%(14/57),respective-ly.Children group had more adverse events than the juvenile group(P =0.039)and adolescent group(P =0.045).Conclusion Pediatric ERCP is highly effective in the pediatric population with chronic pancreatitis. The incidence of post ERCP adverse events is higher among the youngest children.

ObjectiveTo investigate the diagnostic value of EUS-FNA for pancreatic masses and correlated influential factors. MethodsWe retrospectively analyzed the clinical data of 101 patients with pancreatic lesions who underwent EUS-FNA from January 2008 to January 2010. The clinical data enrolled 10 factors including patient gender, patient age, lesion location, lesion size, lesion characteristics, negative suction pressure, times of access, real-time cytological diagnosis, type of EUS and operators' experiences.ResultsThe overall diagnostic accuracy, sensitivity, specificity, positive predictive value and negative predictive value of EUS-FNA were 85. 1％, 81.1％, 96. 3％, 98. 4％ and 65.0％, respectively. Univariable logistic regression analysis indicated that lesion size, lesion characteristics, negative suction pressure, operators' experience were correlated factors of EUS-FNA positive rate, while lesion size was the only correlated factor of EUS-FNA diagnostic accuracy ( OR =1. 984,95 ％ CI: 1. 141 ～ 3. 451, P =0. 015 ). Every 1 cm the lesion increased, by 1.67 times of opportunity the positive rate became, by 1.83 times of opportunity the accuracy was. The lesion size and lesion characteristics were independent correlated factors of EUS-FNA positive rate (OR=2.012, P=0.000; OR =10.218, P=0. 002). The positive rate of EUS-FNA in solid lesions was 10. 2 times of that in cystic lesions. Lesion size was the independent correlated factors of EUS-FNA diagnostic accuracy (OR =1. 984, P =0. 015 ). ConclusionEUS-FNA can effectively make a pathological diagnosis of pancreatic masses with high diagnostic accuracy and specificity. EUS-FNA diagnostic positive rate and accuracy were both positively correlated with pancreatic lesion size. EUS-FNA positive rate of solid pancreatic lesions is significantly higher than that of cystic lesions.

Objective To compare the diagnostic yield of endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) for solid pancreatic masses performed with three different needle types through the cytological results.Methods All patients with solid pancreatic masses larger than 2cm from December 2010 to May 2011 were enrolled,and divided into two groups according to different access of EUS-FNA,trans-gastric approach with 19-,22-and 25-gauge needles (n =42) and trans-duodenal approach with 22-and 25-gauge needles (n =10).In both groups,EUS-FNA was performed with randomization of needle types.During the puncture,the suction,the number of movements,and the depth of insertion were fixed.At the end of the puncture,a liquid-based cytological (LBC) preparation was used to fix the specimen.One cytopathologists was assigned to make the diagnosis and comparison.Results Technical success was 100％ and no procedure related complications occurred.No statistically significant differences were observed in different needles in terms of all cytological parameters between two groups (P ＞ 0.05).However,the 25-gauge needle showed a trend towards a higher sensitivity,specificity,positive predictive value,negative predictive value and accuracy.Conclusion There is no significant difference in yield of cytological results between different needle types,although 25-gauge needle shows a relative superiority.

Objective To investigate a Chinese pedigree suffering from Leydig cell hypoplasia ( LCH) based on clinical data and genetic diagnosis. Methods The patient was diagnosed by means of clinical data, hormone profiles, and human chorionic gonadotropin ( hCC) test. The luteinizing hormone/chorionic gonadotropin receptor(LHCGR) gene of the patient and family members was amplified and sequenced. Results The patient presented with male pseudohermaphroditism, low level of testosterone, which did not respond to hCG. Genetic analysis of the LHCGR revealed two novel mutations: a missense mutation located in exon 5, resulting in Ile replaced by Thr in the extracellular domain; and a splice site mutation in the 3' terminal of intron 6( IVS6-3 C→A). Proband's sister (46, XX) who lacked clinical manifestations showed the identical genotype with the patient. Conclusions A mutation in the consensus sequence of 3' splice site, in addition to a missense mutation (Ile 152Thr)in the extracellular ligand-binding domain is the cause of inactivation of the LHCGR gene in patient with Leydig cell hypoplasia.
