Objective To investigate the case of left-semicolon cancer with intestinal obstruction for the methods of one-stage resection and anastomosis.Methods The clinical data of ten patients with left-semicolon can- cer with intestinal obstruction treated by transanus ilues tube,were restrospectively analyzed from October 2004 to December 2006.Results No postoperative anastormotic leakage was found and the patients were clinically cured. Conclusion The technical problem that left-semicolon cancer with obstruction for one-stage resection and anastomo- sis was resolved by the application of transanus ilues tube.

A case of varicella pneumonia, hepatitis and pancreatitis after kidney transplantation was retrospectively analyzed. One week after kidney transplantation, the patient had a papule with pruritus, which was diagnosed as varicella by dermatologist as well as high-throughput sequencing. The patient was found to have pneumonia, hepatitis and pancreatitis. The individualized treatment regimen was used, including the dosage reduction of immunosuppressive agents, the blood drug concentration monitoring, antiviral therapy, anti-infection therapy, supportive treatment, and symptomatic alleviation for complications. The treatment was adjusted according to the indicators'variation. The timely review of the indicators and immunosuppressant blood concentration were performed to protect the transplanted kidney function, and the patient recovered in time. This rare case of postoperative complications of kidney transplantation were summarized and analyzed in order to accumulate clinical experience for the treatment of renal transplantation.

Objective To investigate the infect capability of recombinant adenovirus mediated PDGF to human umbilical cord derived mesenchymal stem cells (MSCs). Methods The PDGF cDNA sequence was amplified with RT-PCR and constructed recombinant adenovirus vector AdPDGF. The human umbilical cord derived MSCs were isolated and cultured. In vitro AdPDGF infected MSCs with various MOI,and determine the efficiency using FACS and fluorescence microscope. Trypan blue and MTT assay was used to detect cell viability and proliferation. ELISA was used to quantify PDGF secretion. Results Recombinant adenovirus AdPDGF was successfully and constructed,in which infection efficiency to MSCs was dose dependent. The highest efficiency was around 87.36 % when MOI =50,at which cell viability and proliferation wasn' t impaired. Cell viability of uninfected,AdPDGF infected and control virus infected MSCs was (97.8 ±2.3) %,(91.9±4.0) % and (92.8±4.0) %,separately. The cell proliferation was (100±16.8) %,(95.9±12.0) % and (87.5±9.7) %,separately. There was no statistic significance among AdPDGF infected,control virus infected and uninfected MSCs. 48 hrs post infection,PDGF secretion can be measured from infectious MSCs' supernatant. The secretion level was (1.53±0.37),(3.03±0.68) and (5.25±0.92) ng/ml,separately,when MOI= 10,30,50. No PDGF can be detected from MSC-GFP and control MSC group. Conclusion Recombinant adenovirus AdPDGF was constructed and can infect human umbilical cord derived MSC at high efficiency.

Objective To study the detection rate of early esophageal carcinoma using magnifying endoscopy,and to evaluate the relationship between the imaging patterns of microvasculature change and his- tological diagnosis.Methods Two hundred and fourteen patients with esophageal mucosa roughness,ero- sion,plaque,abnormal color and indentation in conventional endoscopy and 16 healthy volunteers were en- rolled.The magnifying endoscopy images were graded as four patterns by intraepithelial papillary capillary loop(IPCL)changes after iodine dyeing.The biopsies underwent pathologic evaluation.The comparison be- tween the imaging patterns of endoscopy and histological diagnosiswas was evaluated.Results 80.4%(90/ 112)esophagitis was type 2,and 85.7%(12/14)early esophageal carcinoma was type 3 and type 4.The difference was significant between early esophageal carcinoma and normal mueosa(?~2=27.32,P

0.05).Conclusion FT3 ,T3 play some potentially roles in the pathogenesis of ADHD and TSH may not be related to it.

This study was to build a canine portal hypertension model by intra-portal administration of high polymer material polyurethane and organic solvent tetrahydrofuran mixed solutions in order to evaluate the effectiveness of the model. Twelve local crossbreed dogs were selected randomly, with intra-portal administration of 8% (weight/volume) polyurethane- tetrahydrofuran solutions through an incision in the upper abdomen to build the portal hypertension model. We measured the portal vein pressure before modeling, during modeling, and four-, eight-, and twelve- weeks after modeling, respectively. Then we evaluated the effectiveness of the model comparing values of data with those data obtained before modeling started, which were regarded as the normal values. The results showed that the portal vein pressure rose by 2. 5 times after the solution administrated instantly as much as that before modeling, and maintained at 1. 5 times after 4 weeks. This method presents an easy operation, low animal mortality and reliable model of portal hypertension. Its less abdominal adhesions and its ability in keeping normal anatomic structure specially make it suit for surgical research of portal hypertension.
