Objective To investigate the effects of nutritional support on the hypermetabolism of patients with digestive tract fistula complicated with severe abdominal infection. Methods Twenty-nine patients with digestive tract fistula complicated with severe abdominal infection were administered parenteral nutrition (PN) for 4 to 8 days, and then followed by enteral nutrition (EN) or EN + PN. The body weight, serum albumin, transferrin, prealbumin, fibronectin were monitored before and on the 10th and 28th day after nutritional support. Results The levels of serum prealbumin and fibronectin were increased significantly on the 10th day after nutritional support (t = 3.72, 3.52, P <0.01). The body weight, the levels of serum albumin, transferrin, prealbumin and fibronectin were significantly higher than those before nutritional support (t=3.97, 6.57, 7.09, 3.51, 3.58, P<0.01). Conclusion Nutritional support is effective in alleviating hypermetabolism of patients with digestive tract fistula complicated with severe abdominal infection.

Objective To observe the effect sling exercise therapy (SET) and Tuina on radicular cervical spondylosis. Methods From August, 2015 to December, 2016, 72 patients with radicular cervical spondylosis were randomly divided into control group (n = 36) and trial group (n = 36), who accepted traction and SET+Tuina, respectively, for four weeks. They were measured F-wave conduction velocity with electromyogram from median nerve and ulnar nerve, somatosensory evoked potential (SEP), and current perception threshold (CPT) before and after treatment. The clinical ratio of improvement was calculated. Results The ratio of improvement was 83.33% in the trial group more than 58.33% in the control group (Z = 2.093, P < 0.05). F-wave conduction velocity increased in both groups after treatment (t > 12.059, P < 0.001), and increased more in the trial group than in the control group (t > 3.266, P < 0.01); while the latency of SEP decreased in N9 and N13 in both groups (t > 7.061, P < 0.001), and decreased more in the trial group than in the control group (t > 8.033, P < 0.001); the grade of CPT decreased in both groups (t > 8.895, P < 0.001), and decreased more in the trial group than in the control group (t = 8.913, P < 0.001). Conclusion The combination of SET and Tuina can promote the repair of nerve conduction of cervical spondylotic radiculopathy.

Objective To explore the effect of different cold ischemia (CI)times on the patterns of intra-graft T cell activation gene-3 (TCA-3) expression early after isogeneic half liver transplantation (PLT)in mice. Methods The models of C57BL/6 full-size(FS) and PLT were established.The CI time was 1,4 and 8 h.Specimen were collected at 4 and 24 h post-reperfusion.Ribonuclease protection assays (RPA)was used to evaluate serial mRNA expression of the TCA-3 chemokine in all mice.Histopathology was used to examine cold ischemia injury in the liver grafts. Results A total of 45 control and 30 PLTs were performed.The survival rate at 7 day after control and PLT was 100%.Quantitative analysis demonstrated the levels of TCA-3 mRNA expression were low at 4 h after reperfusion in control group with 1,4,8 h CI.The levels of TCA-3 significandy increased at 4 h after reperfusion in PLT group with CI of 1,4,8 h and the difference between the two groups was statistically significant ( F =7.41,P < 0.05 ). TCA-3 mRNA expression significantly decreased at 24 h after reperfusion in two groups. But the difference was not statistically significant ( P > 0.05 ). Histopathology showed severer cold ischemia injury in PLT grafts compared with control grafts. Conclusions The expression of TCA-3 significandy increased early after PLT and played an important role in cold ischemia injury.TCA-3 could be used as the early therapeutic target for reducing ischemia injury in PLT grafts.

Objective To observe the effects of exogenous interleukin (IL)-6 on survival time and regeneration of liver grafts in an orthotopic liver transplantation model in IL-6 knockout (KO) mice.Methods A model of liver transplantation in C57BL/6 wild type (WT) and IL-6 KO mice with C57BL/6 background was established. Grafts were preserved at 4 ℃ in UW solution before transplantation.Study was divided into 4 groups:IL-6 KO→IL-6 KO control group,IL-6 KO→C57BL/6 WT group,IL-6 KO→IL-6 KO+ rIL-6 group,and IL-6 KO→C57BL/6 WT+ rIL-6 group.Recipient animals were injected subcutaneously with human recombinant IL-6 (1 mg/kg body weight) 1 h before transplantation.Survival of liver grafts after transplantation was followed up.Hepatocyte replication with BrdU uptake after liver transplantation was examined by irnmunohistochemistry.Results A total of 48 liver transplantations were performed.Cold ischemic time was 50 min.The survival time of liver grafts in the control group was 2.2 days,and that was 1.9 days,>17.6 days and >20.4 days in IL-6 KO→C57BL/6 WT group,IL-6 KO+ rIL-6 group and C57BL/6 WT+ rIL-6 group respectively with the the difference being statistically significant among the latter three groups (P<0.01 ).The liver grafts transplanted in control group recipients showed patchy areas of necrosis and hepatocyte ballooning.Slight increase in BrdU uptake was found at 48 h post-transplantation.Minimal injury and no necrosis were observed in IL-6 treated groups.Mild increase of BrdU uptake was demonstrated at 48 h after liver transplantation. Conclusion Exogenous recombinant IL-6 appears to significantly prolong the survival time of IL-6 KO liver grafts after liver transplantation and enhance the regenerative response after liver transplantation in IL-6 KO mice.

BACKGROUND: Tumor recurrence in liver transplant recipients greatly affects prognosis of liver transplantation with hepatocellular carcinoma (HCC). How to prevent tumor recurrence has aroused increasing attention. Arsenious acid chemotherapy is considered effective on treating moderate or advanced liver cancer, but its utilization following liver transplantation remains few. OBJECTIVE: To explore the role of arsenious acid on tumor recurrence in liver transplant patients with primary HCC extending Milan criteria. RESULTS AND CONCLUSION: All patients were routinely followed up for 3-32 months. Thirty recipients were presented with tumor recurrence, 16 in the chemotherapy group and 14 in the non-chemotherapy group. Tumor recurred in lung, liver graft and bones in most cases. The total recurrence rate was similar in these two groups, but chemotherapy could delay recurrence after transplantation (P=0.026). There was no significance in 6-month, 1-year survival rate between two groups, but the 2-year survival in the chemotherapy group was higher (P=0.037); 6-month tumor-free survival rates in the two groups had no significance, 1-year and 2-year tumor-free in the chemotherapy group were significantly higher than those in the non-chemotherapy group (P=0.030, 0.023). Intravenous arsenious acid chemotherapy can delay tumor recurrence and prolong survival in liver transplant patients with HCC extending Milan criteria.
