Objective To study the effects of administration of donor apoptotic bone marrow cells via portal vein on the survival time of heart transplantation in rats.Methods Wistar rats were selected as donors and SD rats as recipients, and divided into 4 groups at random. In groups A, B and C, the animals were injected via portal vein with RPMI 1640 0.5 ml 6 as control group, 5?107 donor bone marrow cells and 5?107 apoptotic donor bone marrow cells 6 days before transplantation, respectively , and not subjected to cyclosporin A (CsA). In group D, the animals were injected intra- peritoneally with CsA 5 mg/kg from 3 days before transplantation till 10 days post operation. Bone marrow cells apoptosis was induced by 60 Co? radiation. Heart transplantation models were established in each group. The survival time of donor heart and histological changes were observed. Serum concentrations of IL-10 and TGF-?_1 of recipients and mixed lymphocyte reaction (MLR) were measured. Results The survival time of heart allografts in the group C ( 14.00 ? 0.95 ) was significantly longer than in group A (P

Objective To compare two different gastric tube insertion methods on neonatal pain responae.Methods From April to July 2010,47 neonatal patients underwent gastric tube insertion in the neonatal department of our hospital were randomly classified into two groups:the nasal gastric tube insertion group(28 cases) and the oral gastric tube insertion group( 19 cases).Neonatal pain score and incidence of complications during gastric tube insertion between both groups were compared.Results The mean rank of pain scores were significantly higher in the nasal gastric tube insertion group than in the oral gastric tube insertion group.The incidence of pain and complications were higher in the nasal gastric tube insertion group than in the oral gastric tube insertion group.Conclusions The impact of oral gastric tube insertion on neonatal pain response is not significant,and few complications occur during oral gastric tube insertion,so it is worthy of clinical application.

Objective To observe the effect of GPR30 agonist G1 on high glucose-induced endoplasmic reticulum stress ( ERS) in endothelial EA .hy926 cells.Methods EA.hy926 endothelial cells were divided into three groups:nor-mal control group (Con, 17.51 mmol /L glucose), high glucose (HG, 33.3 mmol /L), high glucose +G1 group (HG+G1, HG +1 μmol/L G1).The apoptosis rate of endothelial cells was measured by flow cytometry , the protein expres-sion changes of ERS related molecules Bip , IRE1, PERK and apoptotic molecules Bax , Bcl-2 were measured by Western blot, the mRNA expressions of Bip and CHOP were measured by RT-PCR assay.Results Compared with Con group , the apoptosis in HG group was significantly increased (P <0.01), Bip, IRE1, PERK and apoptotic molecule Bax were upreg-ulateded (P <0.05, P<0.01 or P <0.001), Bcl-2 downregulatted (P <0.01) and Bip mRNA, CHOP mRNA expres-sion were upregulated (P <0.001 and P<0.01).Compared with the HG group, apoptosis rate in HG +G1 group was significantly lower (P <0.05), BIP, IRE1, PERK and apoptotic molecules Ba.0 downregulated ( P <0.05 or P <0.01), Bcl-2 expressions was increased (P <0.05), Bip mRNA and CHOP mRNA expression were decreased (P<0.001 or P<0.01).Conclusion GPR30 agonist G-1 inhibits EA.hy926 ERS in endothelial cells.

Objective To explore the quadriceps muscles function in patients with unilateral knee injury.Methods 23 unilateral knee injured patients with joint dysfuntion were assessed with isometric EMG activity of vastus lateralis (VL), vastus medialis obliques (VMO) and rectus femoris(RF) of both thighs during three 5-s maximal isometric voluntary contractions at a knee joint angle of 30° (0° - full knee extension), and the torque were recorded at same time. Results The average amplitude (AEMG), mean power frequency (MPF), and median frequency (MF) of VL, VMO and RF in affected knees were significantly lower than those in unaffected knees（P＜0.01）, as well as the torque（P＜0.01）. In the unaffected side, the AEMG, MPF of VL were higher than VMO and RF（P＜0.05）, and RF than VMO（P＜0.05）. In the affected side, the AEMG, MPF of RF are higher than VMO and VL（P＜0.05）, and VL than VMO（P＜0.05）. Conclusion sEMG can provide quantitative measurements of muscle function. The isometric strength and neuromuscular activation lever are lower in affected limb, RF may be affected less than VL and VMO in knee injured patients with knee dysfunction.

Objective To investigate the infection of Helicobacter pylori infection on the serum concentration of homocysteine (Hcy) and its relationship with coronary heart disease (CHD) .Methods 159 cases of patients with CHD were selected as the re‐search subjects .They were divided into two groups :infection group and non‐infection group ,according to the results of 14 C‐urea breathe test .And they were also divided into three groups :negative group ,mild infection group and severe infestation group ,accord‐ing to the severity of infection .The CHD patients infected Helicobacter pylori were divided into three groups:low risk group ,mod‐erate risk group and high risk group ,according to SYNTAX scores .The serum Hcy concentration was determined by cyclic enzy‐matic method .Results Comparing with non‐infection group ,the serum Hcy concentration significantly increased in infection group (P<0 .01) .With the aggravation of Helicobacter pylori infection ,the serum Hcy concentration increased .There were significant difference among negative group ,mild infection group and severe infestation group (P<0 .01) .In the CHD patients infected Heli‐cobacter pylori ,the serum Hcy concentration also increased with the aggravation of the severity of coronary lesion .And there were significant difference among low risk group ,moderate risk group and high risk group (P<0 .01) .Conclusion Helicobacter pylori plays a role in the incidence and development of CHD through increasing the serum Hcy concentration .

Objective To investigate the clinical significance of tumor related gene gankyrin expression in pancreatic cancer.Methods The immunohistochemical staining was performed to study the gankyrin expression in 62 pairs of pancreatic cancer and matched non-tumor tissues.The correlations ofgankyrin expression with pathological parameters and the influences on the prognosis were analyzed.Results Ggankyrin positivity in pancreatic cancer and matched non tumor tissue was 2.5％ (45/62)and 19.4％ (12/62),respectively.The positivity of gankyrin was significantly higher in pancreatic cancer compared with matched non-tumor tissues,and the differences were statistical significant (P ＜ 0.01).Gankyrin expression in pancreatic cancer tissues were significantly correlated with TNM stage,differentiation and metastasis (P ＜ 0.05),but not with age,gender or tumor location (P ＞ 0.05).The 3-year survival rates of patients with positive and negative gankyrin expression were 17.8 ％ (8/45)and 41.2％ (7/17),respectively.Patients with positive gankyrin expression had a significantly shorter survival period compared with these with negative expression in pancreatic cancer tissues (P =0.034).Conclusions Gankyrin was overexpressed in pancreatic cancer,which was correlated with poor prognosis.
