Objective To investigate the relationship between the presence of circulating tumor cells (CTC) and the clinicopatho-logic characteristics of primary lung cancer patients .Methods Samples of peripheral blood(7 .5 mL) from 65 cases of patients with lung cancer(lung cancer group) and 10 cases of patients with lung benign diseases and 10 healthy volunteers (control group) ,and then those CTC were enriched by negative immunomagnetic separation with anti-CD45 antibody and then dectected by immunocyto-chemistry with anti-pan-cytokeratin antibody .The relationship between the positive rate of CTC and clinicopathologic characteristics of lung cancer patients were analyzed .Results The positive rate of CTC in lung cancer patients was 69 .23% (45/65) ,while CTC was not detected in any patients with lung benign disease or healthy volunteers .The positive rate of CTC in patients at TNM stageⅠ - Ⅱ ,Ⅲ and Ⅳ was 23 .08% (3/13) ,50 .00% (6/12) and 90 .00% (36/40) ,respectively .There was significant difference in posi-tive rate of CTC between patients at different TNM stages (P= 0 .000) .The positive rate of CTC in metastatic (stage M1 ) lung cancer patients(83 .33% ,35/42) was significantly higher than that in non-metastatic(stage M0 ) lung cancer patients(43 .48% ,10/23)(P=0 .002) .With the increasing number(0 ,1 ,2 ,3) of metastatic sites ,the positive rate of CTC increased (53 .48% ,83 .33% , 87 .50% ,75 .00% ) ,and there was significant difference in different positive rates of CTC (P=0 .024) .There was statistically sig-nificant difference in the positive rate of CTC between Cyfra 21-1 normal group(53 .33% ,16/30) and high value group(92 .00% ,23/25)(P=0 .021) ,the same with LDH normal group(55 .00% ,22/40) and high value group(82 .86% ,29/35)(P=0 .004) .Conclu-sion CTC were presented in some lung cancer patients .The presence of CTC in peripheral blood is correlated positively with the patients′clinical stage ,M stage ,the number of metastatic sites ,Cyfra21-1 value and LDH value .CTC detection is useful for more accurate risk assessment of patients with lung cancer .

Objective To explore the influencing factors of the implementation of general hospital guiding principles of nursing classification (trial) in clinical nursing work.Methods 152 nurses and 143 doctors were selected from three 3A-level hospitals in Changchun and were investigated with self-designed questionnaires,and the data were statistically analyzed.Results The first three influencing factors were the responsibility,quantity and basic qualities of nurses.Grading nursing standards,leadership value degree and the differences of disease had lower influencing degree.There were cognitive differences between nurses and doctors on the influencing factors on implementation of the principle.Conclusions To improve execution of the principles,the cognition of doctors and nurses on the principles must be unified.Increasing nurses' basic quality and responsibility and carrying out effective human resources management are very useful.

Objective To evaluate the relationship between von Hippel-Lindau (VHL) gene mutations and the prognosis of Chinese sporadic clear cell renal cell carcinoma (CCRCC). Methods VHL gene mutations were detected by polymerase chain reaction (PCR), direct DNA sequencing in 74 paired specimens of sporadic CCRCC and normal kidney. The mutation findings, pathologic fea-tures and prognostic characteristics were analyzed. Results Fifty-one patients (68.9%) were in clinical stage T1, 9 patients (12.2%) were in T2 and 14 patients (18.9%) were in T3. In the aspect of pathological grade, 15 patients (20.3%) were in G1, 50 patients (67.6%) were in G2 and 9 pa-tients (12.2%) were in G3. VHL gene mutations were detected in 40 of 74 cases (54.1%). There were no significant differences of VHL gene mutations in different pathological grade and clinical stage of CCRCC, P=0.915, P=0.237, respectively. All patients were followed up for 34 to 107 months (mean 71 months). Seven patients died of CCRCC. Another 11 patients developed CCRCC related me-tastasis. Five-year tumor-free survival was 78%. The incidence of death or metastasis of CCRCC in VHL gene mutation group (15.0%, 6/40) was significant lower than non-mutation group (35.3%,12/34), P=0.043. Logistic regression results showed that lower tumor pathological grade and stage, better patients' prognosis would be (P=0.016, P=0.024, respectively). However, VHL gene muta-tion was related with better prognosis (P=0.033). This association was stronger among patients with high grade tumors (G3, P=0.048). Conclusions There are frequent VHL gene mutations in spo-radic Chinese CCRCC. Tumors' pathological grade and clinical stage are the important parameters for prognosis. However, VHL mutations are strongly associated with better cancer specific survival for CCRCC patients. These associations are relatively stronger in patients with high grade tumors.

Objective To investigate the effect of probucol on Sertoli cell injury induced by oxygen-glucose deprivation/reoxygenation(OGD/R)and mechanism. Methods Primary Sertoli cells treated with oxygen glucose deprivation for 2 h and reoxygenation for 3 h were modeled. We incubated Sertoli cells with probucol in a concentration of 5,10,and 20 μmol/L from reoxygenation to the end. The cell viability was evaluated using Cell Proliferation Assay kit. ROS production was observed by flow cytometry. The levels of MDA ,iron and GSH or the activity of glutathione-dependent peroxidase were measured by Assay Kit. Results The ferroptosis inhibitors pre-vented cell death(P < 0.01). The cell death rate was decreased by probucol in time- and dose-dependent manner (P < 0.01). Meanwhile, probucol caused increase of ROS,MDA,GSH content and GPXs activity(P < 0.05). Conclusion Probucol protects Sertoli cells from OGD/R damage via inhibiting lipid peroxidation-mediated ferroptosis.
