Objective: To construct an adenovirus vector encoding mouse PGC1? gene for further study on its function. Methods: Recombinant shuttle plasmid pAdTrack-CMV-PGC1? was linearized by PmeⅠ and transformed into Escherichia coli BJ5183 carrying backbone plasmid pAdeasy-1 to obtain adenovirus plasmid through homologous recombination. The recombinant adenovirus plasmid was digested by PacⅠ and transfected into HEK293 cells to form adenvirus particles. The virus titer was determined by TCID50 method. The expression of PGC1? in 293 cells was detected by Western blot. Results: The packaging cell showed typical CPE,and the virus titer was about 3?1010 TCID50/ml after amplification. The expression of PGC1? mediated by the recombinant adenovirus vector was verified by Western blot. Conclusion: The adenovirus vector encoding mouse PGC1? gene was successfully constructed,and the protein was observed in 293 cell.

Objective To explore the association between maternal methylene tetrahydrofolate reductase (MTHFR) C677T polymorphism and neural tube defects (NTDs). Methods CBM, VIP, CNKI, Wanfang, PubMed and Web of Science databases from set up to March, 2014 were electronically searched to identify case-control studies on the relationship between maternal MTHFR C677T polymorphism and NTDs. The data were quantitatively analyzed by RevMan 5.0 software. Results A total of 25 studies were selected including 2 282 cases and 3 420 controls. Overall, the pooled OR (with 95%CI) under co-dominant model and allele contrast were 2.28(1.60-3.24), 1.25(1.02-1.53) and 1.42(1.21-1.67). Subgroup analysis showed significant association between maternal MTHFR C677T polymorphism and NTDs susceptibility in Asian populations. Conclusion The present meta-analysis suggests that MTHFR C677T polymorphism is significantly associated with maternal risk for NTDs, especially in Asian populations.

BACKGROUND:Microcapsules is one of the main directions of targeted therapeutic dosing system. With a size of several microns to several hundred microns, it can be used for injection, oral, arterial administration and local treatment of targeted organs and other treatment approaches. OBJECTIVE: To prepare rhizoma drynariae total flavonoids/polylactic-co-glycolic acid microcapsules and optimize the preparation conditions. METHODS: The rhizoma drynariae total flavonoids/polylactic-co-glycolic acid microcapsules was prepared by ultrasonic emulsification. The effect of the mass concentration (60, 100, 140, 180 g/L), stirring speed (50, 1 000, 2 000, 4 000 r/minutes), colostrum emulsification time (2, 4, 6, 8 minutes), colostrum water oil ratio (1:5, 1:10, 1:15, 1:20) of rhizoma drynariae total flavonoids/polylactic-co-glycolic acid microcapsules on gross morphology, particle size distribution width and total flavonoids encapsulation efficiency of microcapsules was univariately analyzed. The rhizoma drynariae total flavonoids/polylactic-co-glycolic acid microcapsules with smaler particle size, uniform dispersion and higher encapsulation efficiency was filtered out. RESULTS AND CONCLUSION: The optimum process parameters were as folows: 140 g/L polylactic acid-glycolic acid solution, the stirring speed of 2 000 r/min, the colostrum emulsification time of 6 minutes, and the colostrum water-oil ratio of 1:15. The microcapsules prepared in the optimized process displayed a uniform distribution and its average particle size was (789.8±712.3) nm, which distributed relative narrowly and basicaly less than 5 μm. Microcapsules presented round, with a regular edge under scanning electron microscope. The average encapsulation efficiency was 47.72%.

Objective To analyze the surgical procedure and effect of living-related small bowel transplantation(LR-SBTx) on intestinal function failure caused by short bowel syndrome.Methods A boy, 15 years of age with short gut syndrome, who had only 8 cm of residual small intestine, associated with serious malnutrition and poor D-xylase absorption test (0.226/5h). The donor was the boy's mother. They had a match of 4 loci in HLA. In the first stage of the surgical procedure, 120 cm of ileum from the patient′s mother was transplanted into the recipient. Both ends of the transplanted intestine were exteriorized as stomas on the patient′s abdominal wall. The second stage of reconstruction of the intestine was carried out 6 months after his first operation. The residual small bowel of the recipient was transected, and both of its ends were respectively anastomosed end-to-side to the proximal and distal segments of the graft. The stomas of the graft were left in place. Results The donor and recipient operation went on smoothly. Acute rejection and infection of CMV developed postoperatively and were cured after treatment. The patient was followed-up for 8 months, the graft function recovered gradually postoperatively with increase of body weight. He can ingest a semifluid diet and take care of himself independently. Conclusions LR-SBTx is an effective way to treat short bowel syndrome. The reconstruction of the intestine in two stages for LR-SBTx decreased the risk of complications. Rejection and infection are important risk factors of LR-SBTx.

Objective To explore the monitoring methods for pancreatic graft function after upper abdominal cluster transplantation.Methods Analysis of the clinical data of 5 cases of successful upper abdominal(cluster) transplantation in our center.Results The patients recovered well after the operation.Endocrine and exocrine functions of all the pancreas graft returned to normal without any rejection.Conclusions Dynamic monitoring of blood glucose,C-peptide,blood insulin,blood amylase,urine amylase,amylase in abdominal drainage and duodenal tube decompression drainage,in addition to Doppler color ultrasound examination,can effectively detect the endocrine and exocrine function of the pancreas graft.

Objective To investigate the methods and effectiveness of heterotopic reconstruetion of hepatic artery in orthotopic liver transplantation. Methods The methods of heterotopic hepatic artery reconstruction and postoperative management of 36 cases of recipient vascular anomalies among 440 cases of liver transplantation performed in our hospital over a ten year period,were retospectively analysed. Results In 10 of 36 recipients the donor hepatic artery was anastomosed to recipient infrarenal aorta ,10 to the suprarenal aorta ,4 to the left gastric artery and 2 to the splenic artery. Five patients died perioperatively with patency of hepatic artery, and 31 recipients have survived for 3 to 48 months without hepatic artery complications; 1 patient had to receive liver retransplantation because of ischemic necrosis of bile duct. Conclusions In cases of disease or anomaly of recipient hepatic artery during liver transplantation,the heterotopic reconstruction of donor hepatic artery to the infarenal or suprarenal aorta,splenic artery or left gastric artery of the reeipient is indicated,and the results are satisfactory.
