Objective To evaluate the clinical value of serum carcinoembryonic antigen(CEA),neuron specific enolization enzyme(NSE),21-1 non-small cell lung cancer associated antigen(CYFRA21-1),carbohydrate antigen 125(CA125) and ferritin(Fer) in the diagnosis of lung cancer.Methods The levels of CEA,NSE,CYFRA21-1,CA125 and Fer were measured by electrochemlium-inescence in 103 patients with lung cancer,32 patients with benign lung diseases and 40 healthy people.Results The serum levels of CEA,NSE,CYFRA21-1,CA125 and Fer in patients with lung cancer[(110.2±95.5)ng/mL,(50.6±43.4)ng/mL,(32.8±29.5)ng/L,(122.7±110.4)U/L,(854.6±497.2)ng/mL] were significantly higher than those in patients with benign lung diseases and those in healthy people(t=6.21,5.71,6.75,6.62,7.74,P<0.05;t=5.26,4.86,5.81,5.20,6.26,P<0.05).The sensitivity values of CEA,NSE,CYFRA21-1,CA125,Fer and the combined determination containing five tumor markers were 39.81%,24.27%,71.84%,68.93%,77.66% respectively.The sensitivity and specificity of the combined determination containing five tumormarkers were 96.12%,95.00%.Conclusion The joint detection in the diagnosis of lung cancer could improve the sensitivity significantly,to help for early diagnosis of lung cancer,which is value to widely applied in clinic.

Objective:To study the relation between low density lipoprotein and macrophage myeloperoxidase.Methods:Using the reaction that MPO catalyze the oxidation of o dianisidin hydrochloride,MPO activity was determined.Using reverse transcription polymerase chain reaction(RT PCR),MPO gene expression was determined.The two methods were used to observe the relationship between low density lipoprotein and macrophage myeloperoxidase activity.Results:LDL was able to accelerate the hoist of MPO activity, but its effect is less than LPS OX LDL have no this effect When the time of LDL effect was prolonged, MPO activity was enhancing little by little When the concentration of LDL effect was increased, MPO activity was enhancing to max little by little, then it come to plateau Conclusion:LDL non especially induced the hoist of MPO activity and the swelling of MPO secretion The reason of the hoist of MPO activity was likely to make MPO into action and enhance its secretion, but not MPO gene expression

Objective To study the reliability and validity of the clinical neurologic deficit scale in evaluating stroke patients. Methods A total of 222 inpatients with acute stroke onset were included in the study. They were assessed when admitted, at the 14th and 90th day of hospitalization by different physicians using the clinical neurologic deficit scale. Intrarater and interrater reliability were determined using Kappa correlation. The split-half rehability and internal consistency were evaluated using Cranbach's a coefficient. Concurrent validity and the predictive validity were determined by spearman rank correlation coefficients. Construct validity was assessed by the factor analysis and the construct validity of the scale was measured according to the classifications of the Oxfordshire Community Stroke Project ischemic stroke subtypes in the patients with cerebral infarction. Results The scores of intrarater reliability in all items were higher than 0.6, the score of interrater reliability in the item "walking" was 0.542, the split-half reliability and the internal consistency were good as demonstrated by the score of 0.911 and 0.886 respectively, and assessment of reliability of different methods showed that "strength in upper limb" and "strength in hand", were poor as shown by the score of 0.393 and 0.386 respectively. The scale is highly correlated with the NIHSS ( both P=0.000) in both total and subtypes of stroke patients according to the classifications of the Oxfordshire Community Stroke Project by concurrent validity analysis. There was a high correlation between the scores of the scale and Barthel Index and the modified Rankin scales at the 90th day of hospitalization (both P=0.000). Conclusions The clinical neurologic deficit scale has a good internal consistency. There is concurrent validity between the scale and the NIHSS and could predict stroke outcome. Factor analysis of the scale displays the best construct validity in the patients with partial anterior circulation infarction, and could be used to evaluate the focus of vertebrobasilar artery despite its insensitivity.

Objective: To investigate the impact of stroke unit (SU) on the compliance of secondary prevention in patients with stroke at 12 months after stroke. Methods: Research subjects were stroke patients who were treated in SU (n = 500) and in general ward (GW) (n =445) using a design of retrospective study. The patients in the SU group were followed up by hospital, telephone and home interviews for 12 months, and the patients in the GW group were followed up by telephone interview for 12 months. The main outcome measures were the rate of using antithrombotics, the rate of smoking cessation, and the rates of awareness of early stroke symptom and stroke risk factors of patients. Results: he rate of using antithrombotics was 92.76% in the SU group, and it was significantly higher than 51.49% in the GW group (P ＜0.01); the rate of smoking cessation, and the rates of awareness of early stroke symptom and stroke risk factors of patients were 82.33%, 91.04%, and 94.03% respectively in the SU group, and they were significantly higher than 54.75%, 6.53%, and 70.37% in the GW group(P all ＜ 0.01 ). Conclusions: SU attaches importance to the secondary stroke prevention and emphasizes standardized treatment, and the compliance of the secondary stroke prevention in patient with stroke is improved significantly.

AIM: To investigate the influences of native and oxidized lipoprotein(a) on human arterial smooth muscle cell (SMC) proliferation, change of intracellular free calcium concentration ([Ca 2+ ] i) and the protective effect of sodium ferulate(SF). METHODS: Lp(a) was oxidized by Cu 2+ and the extent of oxidation was assessed by the MDA content.Human SMC were incubated in culture media with SF for 12 h, then exposed to Lp(a) and oxidized-Lp(a), respectively. MTT colorimetry and flow cytometry were used to evaluated the proliferation of SMC and flurorescent indicator Fura-2/AM was used to determined [Ca 2+ ] i. RESULTS: ox-Lp(a) significantly promoted proliferation of SMC and increased[Ca 2+ ] i compared with Lp(a). SF(40,80 mg/L) remarkedly inhibited SMC proliferation and decreased the rising of [Ca 2+ ] i induced by ox-Lp(a) in a dose-dependent manner, but no effect on SMC proliferation and the increase in [Ca 2+ ] i induced by Lp(a).CONCLUSION: ox-Lp(a) induces the strong growth-promoting effect in SMC through increasing in [Ca 2+ ] i, which might be one of the cellular mechanisms responsible for the higher atherogenic potential of ox-Lp(a) compared with Lp(a), and this process can be prevented by inhibiting of oxidation by SF.

Objective:To evaluate the clinical effect of laryngofissure without tracheotomy.Method:One hundred and sixteen cases of laryngofissure without tracheotomy in our department were analyzed retrospectively.Result:Of 116 cases, 101 cases had the laryngeal carcinoma; 9 cases had laryngeal stenosis; 6 cases had benign tumor of larynx. All the incisions were healed by first intention; and postoperative duration of hospital stay were 7 to 20 days. Three cases recurred in 101 cases of laryngeal carcinoma (2.97%), and underwent reoperation,the 5 year survival rate was 100%. One case recurred in 9 cases of laryngeal stenosis, and underwent reoperarion of laryngoplasty with T-tube implanted. No recurrence in 6 cases of benign tumor of larynx.Conclusion:Laryngofissure without tracheotomy have the advantage of less trauma , fast rehabilitation and no destroying the normal respiratory functions. It is completely feasible so long as surgeons grasp the adaption of operation strictly and select suitable cases.

AIM: The purpose of the present study was to detect intracellular Ca 2+ changes in living brain slices during focal cerebral ischemia/reperfusion (I/R) and reveal the role of intracellular Ca 2+ in the cerebral I/R injury. METHODS: The model of focal cerebral I/R was established in rats by reversible inserting a nylon thread, and dynamic change of intracellular Ca 2+ in brain slices was determined using laser confocal imaging system. RESULTS: ① Ca 2+ gradually enhanced with increase in ischemic time in cortex and striatum. ②At 1 h ischemia/ 10 min reperfusion, Ca 2+ increased significantly in striatum, but Ca 2+ decreased at 3 h reperfusion compared with 10 min reperfusion. ③ Ca 2+ markedly enhanced at 6 h ischemia compared with 1 h ischemia, and after 3 h reperfusion Ca 2+ decreased, but was still higher than that in sham-operation group. ④The striatum is more sensitive than cortex to ischemia/reperfusion. CONCLUSION: Ca 2+ overload in the area of cortex and striatum may play an important role in cerebral ischemia/reperfusion injury in rats.
