Objective To investigate whether BNP(brain natriuretic peptide) could be relatively objective index for comprehensive risk stratification of exercise rehabilitation nursing in young and middle myocardial infarction patients. Methods BNP concentration and LVEF were measured respctively in young and middle myocardial infarction patients. Then the risk stratification was administrated based these index respectively and Barther Scores and significant statistical differences were calculated according to homogeneity test for variance. Results Blood BNP concentrations in acute phase among the divided group based on EF risk stratification were significant difference,hence the standard deviation is large,which led to variance nonhomogeneity,and stracification difference between groups is not clear and across-talking. Exercise rehabilitation nursing scores based on echocardiography EF value had significant difference even veariance is nonhomogeneity,hence the differ-ence is not clear beween groups.Exercise rehabilitation nursing scores based on BNP was administrated and significance is clear beween groups. Conclusions BNP concentration and LVEF value had certain relationship and cross-talking among them.Risk stratification based on BNP concentration had objective instructions for exercise rehabili tation nursing in actue infarction myocardial pa-tients.

Objective To study efficiency and safety of fondaparinux and Enoxaparin in treatment of Chinese patients with acute coronary syndrome (ACS) having undergone percutaneous coronary intervention (PCI). Methods One thousand and sixty ACS patients (945 with unstable angina, 115 with AMI) having undergone PCI in Henan provincial hospital from July 2011 to July 2013 were randomized into two groups treated with fondaparinux or enoxaparin respectively. Apart from treatment with oral aspirin and clopidogrel, those in the former group were treated with fondaparinux (2.5 mg IH QD) and the latter with enoxaparin (60 mg IH Q12H) subcutaneously for 2 days before operation, both suspended for 12 h before the operation. All of the patients were given heparin (60 IU/kg) during the operation. After the operation, the therapies with fondaparinux (2.5 mg IH QD) and enoxaparin (60 mg IH Q12H) were resumed subcutaneously for 3 days. Perioperative observation and follow-ups were made in terms of hemorrhage, thrombosis and major adverse cardiac events (MACE) in the patients during the hospitalization period, 2 and 4 weeks after operation. Results Fondaparinux and enoxaparin are both effective on anticoagulation for the patients after PCI. There was no significant difference about the incidence of MACE between the two groups (P > 0.05). But, fondaparinux group had lower incidence of hemorrhage than enoxaparin group (P < 0.05). Conclusion Fondaparinux and enoxaparin both have good anticoagulant activity in Chinese patients with ACS undergoing PCI, but fondaparinux may lower the risk of hemorrhage compared to enoxaparin.

Objective To evaluate the safety,local efficacy and survival rates of isolated pulmonary metastases from colorectal carcinoma treated with CT-guided radiofrequency ablation.Methods A total of 28 patients with isolated pulmonary metastases from colorectal carcinoma were performed with CT-guided radiofrequency ablation (radiofrequency ablation group).The size of the lesion was 1.2-5.0 (2.9 ± 1.0) cm.During the same time,9 patients,who did not take any treatment for isolated pulmonary metastases from colorectal carcinoma,were collected as control group.The size of the lesion was 2.0-5.0 (3.6 ± 1.0) cm.The local progression-free rates and overall survival rates were compared.Results All the cases were able to complete the radiofrequency ablation in radiofrequency ablation group.During and after the procedure,no major complications occurred.The 1-,2-,and 3-year local progression-free rates and overall survival rates in radiofrequency ablation group were significantly higher than those in control group.The local progression-free rates were 89.3％ vs.76.2％,78.6％ vs.33.9％,70.7％ vs.16.9％.The overall survival rates were 96.4％ vs.77.8％,85.7％ vs.44.4％,56.7％ vs.22.2％.The differences between two groups had statistical significance (P ＜ 0.01).Conclusion CT-guided radiofrequency ablation for isolated pulmonary metastasis from colorectal carcinoma is a safe,effective,minimally invasive treatment,and can significantly improve the local progression-free rates and overall survival rates.

BACKGROUND: Studies have shown that mild hypertension and hypothermia both offer cerebral protection against focal cerebral ischemia,and their possible synergistic effect may provide even better neuroprotective effects.OBJECTIVE: To investigate the mechanism of cerebral protection by induced hypertension combined with mild hypothermia against focal cerebral ischemia and reperfusion, through observation of the changes in the infarct volume and blood-brain barrier(BBB) in rats.DESIGN: A randomized controlled experimental study based on experimental animals.SETTING: The departments of neurology of two university hospitals and department of dermatology in a municipal hospital.MATERIALS: The study was carried out in the Laboratory of Department of Neurology, Union Hospital Affiliated to Tongji Medical College, Huazhong University of Science and Technology and Laboratory of Department of Neurology, People' s Hospital of Wuhan University from March to July 2001. Sixty-four Wistar rats weighing 180 to 230 g were purchased from the Experimental Animal Center of People' s Hospital of Wuhan University.INTERVENTIONS: Sixty-four rats were randomly divided into control group, hypertension group, mild hypothermia group, and combined therapy group, each group consisting of 16 rats. Reperfusion was initiated after a 3-hour focal cerebral ischemia of the 16 rats, and at 2 hour during the ischemia, the rats in the hypertension and mild hypothermia group were treated with hypertension for 3 hours and mild hypothermia, respectively, and those in the combined therapy group received both treatment. The rats in the control group received no treatments for ischemia and reperfusion. Twenty-four hours later, all rats were killed for examination.MAIN OUTCOME MEASURES: The scores of neurological deficits, infarct volume and degree of BBB damage.RESULTS: The scores for neurological deficits, infarct size and volume of Even' s blue staining were 2. 12 ±0. 54, (17.65 ±4.78)%, and(56.63± 10.70) mm3, respectively, in hypertension group, and 2. 14 ±0.69,(16. 21 ± 3.79)%, and(53.52 ± 8.44) mm3 in mild hypothermia group,and 1.78 ±0. 61, (11, 31 ±3.64)%, and 38.45 ±5.25 mm3 in combined therapy group, which were all decreased significantly as compared with the control group[2.70 ±0. 64, (28.34 ±4. 13)%, and(94.87 ± 15.34) mm3].The combined therapy group had the smallest infarct size and volume of Even's blue staining among the three treatment groups( P ＜ 0.05).CONCLUSION: Hypertension and mild hypothermia may reduce the infarct volume and alleviate BBB damage during focal cerebral ischemia and reperfusion in rats, and the effects of combined treatment are more obvious.

Objective To evaluate the safety, efficacy and local control effect of CT- guided radiofrequency ablation (RFA) in treating non-small-cell lung cancer (NSCLC) that is inoperable or the surgical treatment is refused by the patient. Methods Between March 2007 and March 2010 at authors’ hospital, a total of 68 procedures of CT-guided RFA were carried out in 60 patients with early stage NSCLC. The patients included 37 males and 23 females with a mean age of 68.5 years. Pathologically, the lesions included squamous cell carcinoma (n=23, 38.3%), adenocarcinoma (n=31, 51.7%), large cell carcinoma (n=2, 3.3%) and adeno-squamous carcinoma (n=4, 6.7%). The mean diameter of the lesions was 3.8 cm (1.8-6.8 cm). The overall survival rate, cancer-specific survival rate and local progression-free survival rate were evaluated. Results RFA procedure was well tolerated by all patients with an average ablation time of 35 min (18-63 min). The main intraprocedural complication was pneumothorax (n=17, 28.3%). No death occurred during perioperative period. The median local progression-free survival time was 28 months, the median survival time was 32 months, and the one-, 2- and 3-year local progression-free survival rate were 94.6%, 83.1%and 73.6%, respectively. Conclusion For patients with inoperable NSCLC and patients with NSCLC who refuse to receive surgery, CT-guided RFA is a safe and effective treatment. This therapy can significantly improve the local progression-free survival rate.

Objective To investigate the expressions of hypoxia inducible factor-1α (HIF-1α) and vascular endothelial growth factor-C (VEGF-C) and the correlations with clinic parameters,and to make sure the effects of the two genes in the lymphangiogenesis and lymph node metastasis of breast cancer.Methods The expressions of HIF-1α and VEGF-C were investigated by means of immunohistochemistry in samples from 78 cases with breast cancer and 20 cases with breast benign lesions.The density of the lymphatic microvessels immunohistochemically stained by D2-40 antibody was calculated.The relationships between HIF-1α,VEGF-C,LVD and clinicopathological parameters were analyzed statistically.Results HIF-1α expression occurred in 52 out of the 78 tumor samples (66.67％),while VEGF-C expression was observed in 41 out of the 78 tumor samples (52.56％).HIF-1α and VEGF-C expressions in breast cancer were significantly higher than those in beingn disease (15％ and 10％ ; x2 =17.26,P =0.000; x2 =11.71,P =0.001).The expressions of HIF-1α and VEGF-C were significantly correlated with regional lymph nodal involvement (x2 =5.80,P =0.016; x2 =7.26,P =0.007) as well as late TNM classification (x2 =8.51,P=0.004; x2 =6.02,P =0.014),disregarding the patient's age,tumor diameter,histological grade and pathologic type (P ＞ 0.05).In addition,HIF-1α expression was positively correlated with VEGF-C expression (r =0.254,P =0.025).Higher LVD was found in both high HIF-1α and high VEGF-C expression cases (t =2.19,P=0.017; t =3.25,P=0.001).Conclusion HIF-1α may play a crucial role in the lymphangiogenesis and lymph node metastasis by regulating the expression of VEGF-C in breast cancer.Therefore,HIF-1α may become a particularly promising target for controlling lymph node metastasis in breast cancer.
