Objective To investigate the patterns of intrathoracic lymph node metastasis in nonsmall cell lung cancer (NSCLC) and to provide a theoretical basis for the delineation of radiotherapy target volume.Methods A retrospective analysis was performed on the clinical data of 314 NSCLC patients after operation.Our focus was to investigate the distribution characteristics and metastatic extent of intrathoracic lymph nodes and their relationship with tumor size,pathological type,and primary site.Comparisons between groups were made by one-way analysis of variance.Results The frequencies of metastases to lymph nodes at stations 4,5,7,10,and 11 were all above 12％,while those at stations 1,2,3,6,8,and 9 were all below 12％.The lymph node metastasis rate was similar on the primary tumor site (P =0.102).The patients with T3 and T4 NSCLC had a significantly higher frequency of N2 lymph node metastasis than those with T1 and T2 NSCLC (17.0％ vs.11.6％,P =0.002) ;the patients with adenocarcinoma had a significantly higher frequency of N2 lymph node metastasis than those with squamous cell carcinoma (34.5 ％ vs.23.2％,P =0.008).Conclusions For patients with T3 and T4 NSCLC of adenocarcinoma subtype,we should highlight the lymph nodes at stations 4,5,7,10,and 11 when delineating the radiotherapy target volume after operation.

Objective To investigate the practical application values of copper sulfate method and hemocyte analyzer in blood do‐nation screening .Methods A total of 1 500 blood samples of donors were randomly collected and determined by using both copper sulfate method and hemocyte analyzer .Taking hemocyte analyzer as the reference method ,the sensitivity and specificity of copper sulfate method for detecting hemoglobin(Hb) were calculated .The overall detection rates of abnormal blood samples determinded by the two methods were calculated ,as well .Statistical comparisons were performed on the test data from both methods .Results A total of 29 donors(accounted for 1 .9% ) with unacceptable Hb value were found by using copper sulfate method .For all blood do‐nors ,the sensitivity and specificity of copper sulfate method for Hb screening before blood donation was 99 .7% and 82 .8% ,respec‐tively .And there were no statistically significant differences in sensitivity and specificity between the two methods for Hb estima‐tion(P>0 .05) .There were 336 donors with abnormal blood samples detected by using hemocyte analyzer .Taking hemocyte analy‐zer as the reference method ,only 8 .6% of donors with abnormal blood samples were screened out by using copper sulfate method . Conclusion The copper sulfate method could be used for Hb screening before blood donation .While because of its limitations ,such as relatively low specificity and inadequate screening items ,the hemocyte analyzer shoud be utilized before blood donation if the con‐ditions permit .

Objective To observe the effect of Rosuvastatin on the function of vascular endothelial and inflammatory response in patients with acute myocardial infarction ( AMI) after intervention. Methods Seventy-eight patients with AMI patients underwent coronary angiography and PCI treatment The patients were divided into the control group (38 patients) and the Rosuvastatin group (40 patients) after PCI treatment All patients were routinely used nitrates, low molecular weight heparin,aspirin,clopidogrel,the Rosuvastatin group were treated on the basis of conventional medication plus service Rosuvastatin 10 mg/time, once a day. Both groups were continuous medicated for 6 months. Cardiovascular events of all patients, the serum lipids, inflammation-related biomarkers and indicators of vascular endothelial function were followed up for 6 months after discharge. Results The cardiovascular events in the Rosuvastatin group (5. 0% ) was significantly lower than that of the control group (18.4%) after discharge within 6 months (χ2 = 4. 52, P < 0. 05). After 6 months of discharge, the serum lipids, the serum IL-6, hs-CRP,plasma ET-1 and ox-LDL of Rosuvastatin group ((2. 16 ±0. 54)mmol/L,(4. 16 ±0. 28)mmol/L,(6. 80 ± 2. 65) ng/L, (4. 02 ± 1. 58) mg/L, ( 62. 45 ± 9. 38) ng/L and 381. 65 ± 39. 73, respectively) was significantly lower than those of the control group ((2.47 ±0. 59) mmol/L, (5. 29 ±0. 31 )mmol/L, (9. 39 ±4. 17) ng/L, (5. 76 ± 1. 52)ng/L, (81. 75 ± 10. 23) ng/L and 485. 91 ±42. 68,respectively) (t =2. 423,16. 910,3. 291,4. 952,8. 691 and 11. 173 , respectively , P <0. 01 ). The serum NO of Rosuvastatin group ( ( 62. 17 ± 17. 69 ) μmol/L) was significantly higher than than that of the control group ( (48. 27 ±18. 35 ) μmol/L) (t = 3.406, P < 0.01 ) .

Objective To observe the factors affecting inadequate ST-segment resolution in patients with acute ST-segment elevation myocardial infarction after emergency percutaneous coronary intervention (PCI). Methods The patients with acute ST-segment elevation myocardial infarction undergoing emergency PCI were enrolled for study. According to the ratio of ST-segment resolution, 186 cases were divided into inadequate ST-segment resolution group (54 cases) and relatively adequate ST-segment resolution (132 cases). Clinical data of two groups were compared. The single factor and multiple Logistic regression analysis were performed to determine the factors influencing inadequate ST-segment resolution. Results Pre-infarction angina was protective factor of inadequate ST-segment resolution after emergency PCI (OR=0.361, 95%CI 0.131-0.994, P<0.05). Anterior myocardial infarction, attack-to-balloon time, Killip classification and white blood cell counts were risk factors of inadequate ST-segment resolution (OR=2.389, 95%CI 1.194-4.781;OR=1.655, 95% CI 1.082-2.532; OR=1.319, 95% CI 1.026-1.695; OR=1.184, 95% CI 1.004-1.396, P<0.05). Conclusions Patients with pre-infarction angina could reduce the risk of inadequate ST-segment resolution after PCI. Patients with anterior myocardial infarction,long attack-to-balloon time, Killip classification≥2 and high blood cell counts could increase the risk of inadequate ST-segment resolution, and earlier and more active clinical intervention should be taken.

Purpose To analyze the gait of patients following reconstruction of posterior cruciate ligament(PCL) and posterolateral corner(PLC).Methods Between March 2007 and April 2008,16 patients with combined PCL and PLC injuries-deficient knee underwent the reconstruction with allograft.Dial test were performed before surgery,and gait analysis and dial test were assessed 1 year after reconstruction.Sixteen healthy volunteers were used as controls.Results There are no differences in the time-distance factors and kinematics between patients and controls(P>0.05).The torque of knee extension revealed significant difference between patients and controls(P<0.01).Mean abtorsion angle of the patients increased 16.5°±6.2° before surgery;whereas the angle increased-4.4°±7.8° 1 year after surgery(P<0.01).The maximal mean abtorsion angnlation from gait analysis was 14.1°±15.7° and from dial test was 29.7°±1 5.2°,respectively.There was a strong linear correlation(r=0.9671,P<0.05)between the outcomes from dial test and gait analysis.Conclusion After reconstruction of the PCL and PLC,the gait of patients became almost normal 1 year after operation,except the torque of knee extension.
