Objective To evaluate the influence of nursing intervention on the self-care of patients with high risks of diabetic foot. Methods Among 60 diabetic patients who have risks of indeed getting diabetic foot. Those risks include peripheral vascular disease and neuropathy, we gave them self-care ability education and nursing intervention. Each patient was given personal self-nursing education. Those patients were followed for 6 months, and were instructed with everyday foot nursing, and self-monitoring management, etc. A year later, we investigated the self-management capability of those patients, and came out with the statistical data of those who go hospital again or catch diabetic foot. Results Before the education, only 16.6％ patients can recognize the risks of diabetic foot, 15％ patients nurse the feet by themselves daily, 13.3％ patients grasp the methods to discern and process the normal foot problems in all 60 patients. After nursing intervention, 84.3％ patients can recognize the risks of diabetic foot, 85％ patients nurse the feet by themselves daily, 86.6％ patients grasp the methods to discern and process the normal foot problems. Diabetic patients with high risks got more nursing knowledge and self-nursing ability after nursing intervention. (t =22. 71,-19.90;P ＜0. 05). 0nly one sample caught diabetic foot. Conclusions Nursing invention can promote the serf-care ability d patients. It has an important role in controlling the diabetic foot risk factors and preventing disease.

Coumarins are a group of important natural compounds, and have been found to have multi-biological activities such as anti-HIV, anti-tumor, anti-hypertension, anti-arrhythmia, anti-osteoporosis, assuaging pain, preventing asthma and antisepsis. One of which is its anti-tumor effect and that is a research focus on. Therefore, we believe that it is necessaryto carry out further studies on the effect of coumarins compounds in anti-tumor. Investigation should emphasize on improving techniques for extraction and separation, searching the effective precursory compound, and synthesizing and screening out courmarin derivatives with high activity and low toxicity. Here the recent research progress in anti-tumor effect of coumarins compounds is reviewed.

Objective To identify the gene mutation of G protein?-subunit (Gsct) in multiple affected tissues of a patient with McCune-Albright syndrome.Methods The peripheral blood,bone tissue,lesion skin and pleura samples of the patient were collected.Genomic DNA was isolated from these samples,and PCR and direct sequencing were performed.Results The peripheral blood and bone tissue of the patient showed a mutation R201C in Gs?gene.No mutation was detected in the skin and pleura samples of the patient.Conclusion The gene diagnosis confirms that the patient has a classical R201C mutation in Gs?gene and multiple tissues are affected.The mutation occurs early in embryogenesis and clinical features can be polymorphic.

BACKGROUNDSeveral techniques have been described for posterior cruciate ligament (PCL) reconstruction. However, double-bundle PCL reconstruction using the quadruple bone-tunnel technique has been seldom reported. The current study investigated this technique, focusing on the anatomy of the femoral and tibial insertions of the anterolateral (AL) and posteromedial (PM) bundles of the PCL.

METHODSTwenty-two fresh, healthy adult cadaveric knees were dissected and measured. The PCL was divided into the AL bundle and PM bundle at the insertion footprint. The insertion footprints of the AL and PM bundles, their location, size, and the clock positions were measured and described.

RESULTSOn the femur, the clock position of the footprint of the AL bundle was 11:21 ± 0:23 (left) or 0:39 ± 0:23 (right), and the PM bundle was 9:50 ± 0:18 (left) or 2:10 ± 0:18 (right), with the knee flexed at 90 degrees. The distances from the center of the femoral insertions of the AL and PM bundles to the anterior cartilage margins of the medial femoral condyle were (7.79 ± 1.22) mm and (8.36 ± 1.63) mm, respectively. On the tibia, the vertical distances from the center of the tibial insertions of the AL and PM bundles to the tibial articular surface were (3.25 ± 1.20) mm and (6.91 ± 1.57) mm, respectively.

CONCLUSIONSThese results have led to a better definition of the anatomy of the AL and PM bundle footprint of the PCL. The technique of double-bundle PCL reconstruction using quadruple bone-tunnel is feasible. Application of these data during PCL reconstruction using the quadruple bone-tunnel technique may help optimize knee stability.

Objectives To investigate the impact of AAV-encoding NT4-TAT-His-PR39 fusion gene expression on HIF-1α level in ECV304 cultured under hypoxic condition ( 1% O2) and on angiogenesis in hypoxic chick embryo. Methods PR39 cDNA was connected with NT4, TAT, 6 x His cDNA by molecular biology methods. The recombinant AAV vector was obtained by three plasmid co-transfection in 293 cells. Then ECV304 were respectively infected with AAV-NT4-TAT-His-PR39, 6 x His expression and HIF-la level in ECV304 were detected by immunocytochemistry. The chicken embryos were randomized into the AAV-PR39, EV and PBS groups ( n = 10 each) subject to hypoxia (5% O2, n = 15 ) or normoxia environments (n = 15) , the vessel density of the chicken chorioallantoic membrane (CAM) were measured by Image Pro Plus (IPP) software. Results The expression of 6 x His protein was detected in AAV-PR39 infected ECV304 cells. HIF-1α protein activity was significantly increased in AAV-PR39 infected ECV304 underwent hypoxia compared to PBS and non-infected ECV304 groups ( P < 0. 05). The vessel density of chicken CAM in hypoxia environment but not in normoxia environment was also significantly higher in AAV-PR39 group than in EV group and PBS group (all P <0. 05). Conclusion AAV-encoding NT4-TAT-His-PR39 fusion gene expression significantly increased HIF-la level in ECV304 exposed to hypoxia and promoted angiogenesis in hypoxic chicken embryo.

OBJECTIVETo investigate the effects of fast track surgery on patients with gastric cancer in perioperative period.

METHODSNinety-two patients with gastric cancer undergone radical operations were randomly divided into two groups: fast track group (n=46, fast track surgery) and control group(n=46, traditional surgery). Serum levels of tumor necrosis factor-alpha (TNF-alpha), interleukin-6 (IL-6) and C reaction protein (CRP) in the 92 patients were assayed preoperatively and at day 1, 3, 7 postoperatively, and the resting energy expenditure (REE) was also measured by indirect calorimetry in the morning. The postoperative hospital stay, duration of fever, medical cost, postoperative time of flatus and postoperative complications were recorded and compared respectively.

RESULTSAt postoperative day 1 and 3, serum levels of TNF-alpha were (12.67+/-2.68) fmmol/L and (13.19+/-2.75) fmmol/L in fast track group, (14.74+/-3.18) fmmol/L and (15.56+/-2.99) fmmol/L in control group; serum levels of IL-6 were (112.52+/-24.73) ng/L and (129.03+/-22.75) ng/L in fast track group, (123.90+/-22.52) ng/L and (142.67+/-20.33) ng/L in control group. The levels of IL-6 and TNF-alpha in fast track group were significantly lower than those in control group (all P<0.05). At postoperative day 1, 3 and 7, serum levels of CRP in fast track group were significantly lower than those in control group [d1(56.20+/-11.47) g/L vs (71.07+/-17.32) g/L, d3(136.09+/-19.78) g/L vs (157.78+/-28.18) g/L, d7 (48.53+/-12.95) g/L vs (64.72+/-19.73) g/L] (all P<0.05). At postoperative day 1 and day 3, the REE in fast track group were significantly lower those than in control group [d1(5713.96+/-619.44) kJ/d vs (6176.04+/-614.46) kJ/d, d3 (5298.49+/-639.36) kJ/d vs (5627.94+/-656.72) kJ/d] (all P<0.05). The postoperative duration of fever [2(2.0-3.0) d vs 4(2.8-4.0) d], postoperative time of flatus [3(2.0-4.0) d vs 4(3.8-5.0) d], postoperative hospital stay [6(6.0-7.0) d vs 8(7.0-8.3) d] and treatment expense [(27 201+/-3857) Chinese yuan vs (31 006+/-3555) Chinese yuan] in fast track group were also significantly lower than those in control group (P<0.01). There were no significant differences in complications between the two groups(P>0.05). The quality of life score on discharge in fast track group was significantly higher than that in control group (15.74+/-1.82 vs 14.67+/-1.27, P<0.01).

CONCLUSIONFast track surgery can ameliorate stress reaction, decrease postoperative patients' REE during perioperative period and accelerate the rehabilitation of patients with gastric cancer.

BACKGROUNDAlthough the introduction of serum prostate-specific antigen (PSA) measurements into clinical practice has revolutionized the care of patients with prostate cancer, there are well-recognized limitations of PSA, and there is a critical need to identify additional prostate cancer biomarkers to assist in early detection and prognosis. In this regard, high resolution proteomic technology has the unexceptionable superiority to find those high abundance biomarkers. The purpose of this study was to search new tumor markers by proteomic technology.

METHODSThe proteins in conditioned medium (CM) of BPH-1 and LNCaP cells were profiled by two-dimensional electrophoresis and identified by matrix-assisted laser desorption ionization mass spectrometry (MALDI-TOF-MS). The corresponding mRNA levels of some identified proteins were analyzed by RT-PCR.

RESULTSTotally 11 differentially expressed proteins (6 up-regulated including creatine kinase, brain (CKB), triosephosphate isomerase 1 (TPI1), isocitrate dehydrogenase 2 (IDH2) and 5 down-regulated including glutathione S-transferase pi (GST-pi)) in the CM were identified using MALDI-TOF-MS and database search. The expression pattern between mRNA and CM protein levels of CKB, IDH2, TPI1 and GST-pi in BPH-1 and LNCaP was similar.

CONCLUSIONWe proved a feasible and effective way to search new tumor markers by a proteomics-based strategy and identified 11 potentially useful proteins in CM of BPH-1 and LNCaP cells to distinguish prostate cancer from benign prostatic hypertrophy.

OBJECTIVETo determine the effect of early enteral nutrition (EN) on immune function of the patients after operation for severe abdominal trauma.

METHODSFourty patients who underwent operation for severe abdominal trauma were randomly divided into two groups, and received an early enteral nutrition (EN group, n=20) through jejunal nutritional tube from postoperative day 1, or parental nutrition (PN group, n=20) for 7 days. C3, IgA, IgM, IgG and CD3+, CD4+, CD8+, CD4+/CD8+ of the two groups patients were detected on the day before operation and the postoperative day 1 and 8. The infection complications were compared.

RESULTSAfter 7 days, the levels of C3+, IgA, IgG, CD3+, CD4+, CD8+, and CD4+/CD8+ in EN group increased significantly compared with those in PN group (P< 0.05). The incidence of infection was 10% in EN group, while 30% in PN group (P< 0.05).

CONCLUSIONEarly enteral nutrition can improve immune function and decrease postoperative infection after operation for severe abdominal trauma.
