Objective To evaluate the usage of renoportal anastomosis in the liver transplanta- tion.Method The successful experience about renoportal anastomosis for portal vein reconstruction in liver transplantation was reported,and related literature reviewed.Results Including our case,there have been 13 cases of liver transplantation using renoportal anastomosis for portal vein reconstruction. Among these patients,8 cases were complicated with diffuse portal vein thrombosis,and 10 cases had a splenorenal shunt(spontaneous shunt in 3 and surgical shunt in 7).Complications related to portal vein hypertension occurred in 3 cases(transient ascites in 2 cases and severe digestive bleeding in 1 case)after liver transplantation.There were 3 deaths which were not related to renoportal anastomo- sis.Conclusion Renoportal anastomosis is a safe and feasible technique in liver transplantation for the patients with diffuse portal vein thrombosis or with splenorenal shunt(spontaneous or surgical shunt).

Objective To improve the diagnosis and treatment of primary adrenocortical carcinoma. Methods Retrospective analysis was performed in clinical data of 16 patients with primary adrenocortical carcinoma. The diagnosis was based on clinical presentations,hormonal studies and imaging. Surgical treatment was underwent on 13 cases. All patients were followed up for 3 to 62 months. Results Of 16 cases,functional tumors were in 8,including Cushing′s syndrome in 5,combination of Cushing′s syndrome and virilization in 2,and hyperaldosteronism in 1. Imaging studies revealed the tumors were 4.8 to 19.5 cm in diameter,average in 7.8 cm. Distant metastasis occurred in 3 cases. Radical surgery was done in 13 cases without distant metastasis,including radical adrenalectomy in 8,adrenalectomy plus nephrectomy in 2,adrenalectomy plus surgical extirpation of intracaval tumor thrombus in 2,and partial resection of the wall of inferior vena cava in 1. Pathologic stages were stage Ⅰ in 2 cases,stage Ⅱ in 8,stage Ⅲ in 3,stage Ⅳ in 3. Among the 11 cases who were treated over 2 years after operation,6 cases were still survival,while 1 case had pulmonary and 1 case had bone metastasis. The other 5 cases survive in average of 26 months. Conclusions Prognosis of primary adrenocortical carcinoma is poor. The keys to early diagnosis are clinical manifestations plus imaging. Surgical treatment is the only effective therapy for the disease.

Objective To investigate the effect of different amplification methods and probes with various length on the results of comparative genomic hybridization (CGH) analysis of pre-implanted single blastomere and to establish the basis for preimplantation genetic diagnosis.Methods Twenty blastomeres of embryo at 6-8 cells stage were randomly divided into A and B group with 10 in each.Twenty peripheral blood lymphocytes from a healthy man were similarly divided into C and D group with 10 in each.Degenerate oligonucleotide primed polymerase chain reaction (DOP-PCR) was used to amplify whole genomic DNA in group A and C,and multiple displacement amplification (MDA) was used in group B and D for whole genome amplification (WGA).The specificity of resultant products was confirmed by amplification of TBX1 gene exon 2.CGH was performed respectively with 250-750 bp and 750-2000 bp probes prepared from the amplified whole genomic DNA.The result of CGH was verified by sex-determining region of Y (SRY).Results (1) Nine of the 10 samples in group A and all in group C were amplifiable by DOP-PCR,but there were multiple non-specific bands in the amplification of TBX1 exon 2 when WGA products were used as templates.When 250～750 bp probe was used in CGH,1 of the 5 blastomeres was failed and another one had different karyotype from that analyzed by SRY.(2) All samples in group B and D were successfully amplified by MDA,and the non-specific bands were significantly less in the amplification of TBX1 exon 2.All 5 blastomeres were successful in CGH with the 250～750 bp probe.Moreover,the karyotype was in agreement with that of SRY.(3) When 750 ～ 2000 bp probe was used,the CGH results were suboptimal.Conclusions In WGA of single blastomere,MDA is superior to DOP-PCR in the stability and specificity.The karyotype image detected by CGH with the 250～750 bp probe is clear and homogenous.

Objective To evaluate the safety of modified sputum induction in moderate to very severe COPD during exacerbation. Methods Ninety patients with moderate, severe or very severe COPD during exacerbation (27 with type Ⅰ and Ⅱ respiratory failure,18 with coronary heart disease, 38 with tachycardia) were chosen as research subjects. All the patients underwent induced sputum. During induction , all patients were given electrocardiographic monitoring and pulmonary function check every 5 minutes and FEV1, HR, SpO2 in the process of testing were recorded. Results Ninety patients underwent 224 sputum inductions progress, 222 were safety. Qualified sputum samples were collected for 216 times, sputum induction was successful in 96.43% of occasions. Heart rate rising and SpO2 reducing during sputum induction mainly occurred in the beginning 5 minutes, FEV1 did not change in the whole process. Conclusion Modified sputum induction can be safe through closely monitoring in patients with moderate-to-very severe COPD with exacerbation, even with type Ⅰ or typeⅡ respiratory failure. But the risk of sputum induction will increase if patients with coronary heart disease and tachyarrhythmia, especially within beginning 5 minutes of sputum induction.

Postoperative pancreatic leakage remains a persistent problem after pancreaticoduodenectomy.For patients with a soft and nonfibrotic pancreas,double binding continuous hemstitch suture is an optimal method for anastomosis.From January 2011 to June 2012,92 cases of periampullary carcinoma with a soft pancreas underwent pancreaticoduodenectomy,and then a modified technique of pancreaticogastrostomy was performed with 2 continuous hemstitch sutures placed in the mucosal and seromuscular layers of the posterior gastric wall,respectively.The median time for pancreaticogastrostomy was 12 minutes,and only 15 patients had postoperative complications.Two patients developed pancreatic leakage(1 grade A and 1 grade B)postoperatively.Pancreaticogastrostomy with double binding continuous hemstitch sutures is a simple and safe reconstruction procedure for patients with a soft and fragile pancreas who received pancreaticoduodenectomy.
