Objective To evaluate the preoperative nutritional status of the patients which were preparing for cardiac valves replacement using nutrition risk screening 2002 (NRS2002),and analyze the evaluation effect and bring forward the corresponding nursing interventions.Methods 226 patients who would carry out cardiac valves replacement in the context of extracorporeal circulation were evaluated by NRS2002 preoperatively.88 patients had nutrition risk.Those elective 88 patients were randomly assigned into the experimental group and the control group,each had 44 cases.Then different nursing measures were implemented in each group and the clinical outcome was contrasted in the two groups.Results In the patients who were preparing for cardiac valves replacement,88 cases had preoperative nutrition risk score ≥3 points and 138 cases ＜ 3 points.Preoperative nutrition risk score had positive correlation with heart function grade.Difference of the experimental group and the control group in length of stay,length of mechanical ventilation after surgery and incidence rate of general complications had statistical significance.Conclusions It is effective to analyze the preoperative nutritional status of the patients with cardiac valves replacement by NRS2002.It may improve prognosis effectively by providing preoperative nursing interventions for patients with nutrition risk.Besides,it provides theoretical basis for further studying the relation between nutrition support and clinical outcome of patients with nutrition risk.

Objective To observe the hindpaw withdrawal threshold (HWT), and the ultrastructure and expression of glia cell line-de-rived neurotrophic factor (GDNF) in sciatic nerve (SN) in chronic constriction injury (CCI) rats after pulsed radiofrequency (PRF). Meth-ods 30 Sprague-Dawley rats were divided into sham modeling-sham treating (SS) group, CCI-Sham treating (CS) group and CCI-PRF (CP) group. The right SNs of the rats in the CS and CP groups were ligated, and it was separated without ligation in the SS group. The CP group accepted PRF at the ligation 14 days after modeling, while the electrodes were placed without electricity in the SS and CS groups. Their HWT was measured before and 1, 7, 14 days after modeling, and 1, 7, 14 days after treatment. The right SN of ligation was observed under electron microscope 14 days after treatment, meanwhile, the GDNF expression was determined with enzyme-linked immunosorbent assay (ELISA). Results HWT was significantly shorter in the CS and CP groups than in the SS group after modeling, and it increased in the CP group 14 days after treatment compared with that of the CS group (P<0.01). The degeneration of SN significantly improved in the CP group compared with the CS group, while the expression of GDNF increased compared with that in the CS and SS groups (P<0.01). Conclusion PRF could relieve the CCI-induced neuropathic pain by upregulating the GDNF expression in the SN to prevent the SN from injury.

Objective To investigate the levels of Th1 and Th2 cell in the peripheral and the cytokines (IFN-γ,TNF-α,IL-12,IL-10,IL-4) in the culture medium at different time in the porcine model with multiple organ dysfunction syndrome(MODS) after continuous blood purification(CBP). Methods Twenty-four young porcines were given intravenous infusion of endotoxin to induce MODS, then were randomly divided into 2 groups:CBP group(n = 12) and MODS group without CBP(n = 12). Continuous venovenous hemodiafiltration (CVVHDF) was the main mode for CBP. At baseline, onset of MODS, and 2 h,4 h,6 h after treatment of CVVHDF,we picked the blood respectively to separate the T helper cell using the beads,detected the Th1 and Th2 cell by FACS and detected the cytokines (IFN-γ,TNF-α,IL-12,IL-10,IL-4) in the culture medium by ELISA. Results The MODS group showed a obvious rise in TNF-α,the drop tendency in IL-12,IFN-γ,IL-10,Th1/Th2 ratio, and no significant change in IL-4. After the treatment, the CBP group showed the drop in TNF-α and IL-4;and increase in IL-12,IFN-γ,IL-10 and Th1/Th2 ratio. Conclusion CBP helps to dear immune function,and restore the balance of Th1/Th2 in porcine MODS model.

Objective To study the alveolar macrophages (AM) activation in neutropenic ARDS in children with hematologic malignancy. Methods Thirteen patients of ARDS were prospectively enrolled into the study and divided into two groups,neutropenic (5 cases) and nonneutropenic (8 cases). Bronchoalveolar lavage fluid (BALF) samples were analyzed for differential and total cell counts, and alveolar activation marker expression (HLA-DR) was determined. Results In neutropenic patients,the BALF total cell count and the macrophage absolute count were significantly lower compared to those in nonneutropenic group ((62. 6 ±9. 6)/μl vs ( 124. 0 ± 6. 7)/μl,P ＜ 0. 01 and (40. 8 ±4. 3)/μl vs (67. 6 ± 10. 7)/μl,P ＜ 0. 01,respectively). As compared with the nonneutropenic group, the percentage of AM in neutropenic patients was significantly higher (65.9% ±9. 0% vs 54. 6% ± 8. 7% ,P ＜0. 05) ,the mean percentage of AM HLA-DR expression was significantly lower (35. 3% ± 5.8% vs 62. 2% ± 5. 8%, P ＜ 0. 01 ). Conclusion These results suggest an alveolar hypocellularity and a deactivation of AM in neutropenic ARDS in children with hematologic malignancy.
