Objective: To investigate the effects of enteral nutrition with recombinant human growth hormone (rhGH) on immunological function and inflammatory responses in severe burned rats. Methods: Sixty-four SD rats inflicted by 30% TBSA Ⅲ degree scalds were randomly divided into enteral nutrition with rhGH (ENGH) and enteral nutrition (EN) groups. Two groups animal were fed isocaloric enteral nutrition. Lymphocyte subsets, serum albumin, transferrin, serum levels of immunoglobulins,endotoxin,IL-6,TNF-? were determined on the 1st,4th,7th and 10th day postburn. Results: There were significant postburn changes in inflammatory responses, immunological variables in both groups.CD3 + 、CD4 + 、CD4 + /CD8 + in ENGH group were higher(P

Objective To study the microinvasive treatment of post-gastrectomy acute cholecystisis. Methods Teweenty-eight cases of post-gastrectomy acute cholecystitis were treated by routine non-operative method first, if cases with no apparent relief after 24h of treatment were further treated with percutanous transhepatic gallbladder puncture and drainage(PTGD) guided by ultrasonography. Results Five cases were treated by non-operative method with complete relief within 24 hours. PTGD was done successfully in all the other 23 cases.In cases with ideal bile drainage at the time of intubation, the patients had immediate marked relief of their symptoms and signs, and they fully recovered within 3~7 days.Conclusions Ultrasound guided PTGD is an effective treatment for post-gastrectomy acute cholecystitis with the advantages of microinvasion and quick patient recovery.

Objective: To investigate effect of Zhuanggu Granula medicated serum on proliferation and differentiation of bone marrow stromal cells(BMSCs) in vitro. Methods: Isolated BMSCs were cultured in vitro. The cells were treated with Zhuanggu Granula medicated serum, and the blank serum as the control group. The proliferation of cells was detected by MTT assay, the macroscopic histology, HE staining and immunohistoc-hemical examinations. Results: Zhuanggu Granula medicated serum effectively stimulated BMSCs proliferation (P

Objective To prove the protective effect of lung ischemic preconditioning on enhancing the canine lung preservation and reducing allograft lung dysfunction after transplantation.Methods Ten pairs of adult canines underwent left lung allotransplantation. Five donors were treated with ischemic preconditioning [their left hilus was clamped for 10 minutes and released for 15 minutes (Group IP)], and five donors were not treated with ischemic preconditioning (Group C). The donor lungs were flushed with 4℃ Euro-Collin's solution (ECS) and stored in the same solution for two and a half hour, then transplanted to the recipient canines, who were observed for one to two hours after transplantation. The lung venous blood of the recipient and the donor lung tissue were collected just after thoracotomy and one hour after reperfusion of the transplanted lung in both groups.Results The number of polymorphonuclear (PMN) was significantly higher in Group IP than in Group C (P<0.05). However, the number of PMN in lung interstitium under microscope was less in Group IP than in Group C. The thromboxane (TXB2), malondialdehyde (MDA) and mean pulmonary artery pressure (MPAP) contents were significantly lower in Group IP than in Group C (P<0.05). The superoxide dismutase (SOD) and the lung venous blood oxygen tension (PvO2) contents were significantly higher in Group IP than in Group C (P<0.05). Histological findings showed less damages in Group IP than in Group C.Conclusions The protective effect of ischemic preconditioning together with ECS flush and storage is superior to using ECS alone. The possible mechanisms may be that ischemic preconditioning inhibits the accumulation and activation of PMN in lung tissue and reduces the production of oxygen free radicals.
