Acta Universitatis Medicinalis Anhui.2001;(1):49-51. doi:10.3969/j.issn.1000-1492.2001.01.016

Objective　To study the diagnostic value of pleural fluid telomerase activity in distinguishing a malignant from a benign pleural effusion. Methods　Using a PCR-based assay, telomerase activity was examined in the pleural fluid cells obstained from 69 patients with pleural effusions (37 malignant, 32 benign). Results were compared with cytologic evaluation and carcinoembryonic antigen (CEA). Results　Of the 37 malignant specimens，26（70.27%）contained detectable telomerase activity. The positive rate in malignant pleural effusions was significantly higher than that in benign origin (2/32). Detection of telomerase in effusions was more sensitive than CEA level evaluation for the identification of pleural malignancy (telomerase assay: sensitivity=70.27%, specificity=93.75%; CEA: sensitivity=51.35%, specificity=96.87%). The consistant rate of telomerase with cytology was 54.05%. Conclusion　The detection of telomerase activity may be a useful adjunct to cytopathologic methods in the diagnosis of malignant pleural effusions. It may be useful in differential diagnosis of benign and malignant pleural effusions.

Objective　To observe the influence of intravenous anesthesia with ketamine or propofol on intraocular pressure (IOP) in pediatric patients. Methods　27 pediatric patients, ASA grade Ⅰ～Ⅱ, were divided into ketamine and propofol groups. Basic anesthesia was conducted with ketamine 4～6 mg*kg-1 combined droperidol 0.04～0.1 mg*kg-1 intramuscularly. Anesthesia maintained with continous infusion of 0.04% ketamine or 0.04% propofol following intravenous bolus of ketamine 1 mg*kg-1 or propofol 1 mg*kg-1 in ketamine group and propofol group respectively. IOP, systemic blood pressure(SBP), diastolic blood pressure(DBP), heart rate(HR) and pulse oxygen saturation(SpO2) were measured at 10 minutes after basic anesthesia, 3 minutes after intravenous bolus of ketamine or propofol and end of surgery. Results　There were no differences in IOP between two groups after basic anesthesia. IOP increased or decreased significantly after intravenous bolus of ketamine or propofol respectively. IOP in ketamine group decreased near to the level in propofol group at end of surgery. There were no statistic differences in SBP, DBP and HR between two groups priopration. SpO2 did not change (but in one patient decreasing to below 95% ) and significantly decreased within 5 minutes of intravenous bolus of ketamine and propofol respectively. Conclusion　Ketamine increases IOP propofol decreases IOP. Ketamine combined propofol can keep from increase of IOP but strength respiration inhibition.

Acta Universitatis Medicinalis Anhui.2015;(6):757-760.

Objective To observe the changes of pulmonary oxidative stress after cigarette smoking exposure,its re-lationship with inflammatory cytokines,and the effects of smoking cessation. Methods Fifty male BALB / c mice were randomly divided into the smoke exposure group,smoke cessation group,and the controls. Mice in smoke cessation group were exposed to cigarette smoking for 16 weeks. On 4,8,and 12 week after smoking cessation mice were executed and the bronchoalveolar lavage fluid(BALF)and lung tissue were collected. The morphologi-cal alternations of lung tissue were observed. Mean length of interval and mean alveolar number were measured. Total cell numbers in BALF were counted. Superoxide dismutase(SOD)activity was measured with hydroxylamine method,malondialdehyde(MDA)level was measured with TBA method. The levels of pulmonary interleukin-8 (IL-8)and tumor necrosis factor-α(TNF-α)in BALF and lung tissue homogenate were measured with ELISA. Re-sults Compared with the mice in the controls,emphysematous changes were remarkable in the lung of cigarette ex-posed mice,the total cell numbers in BALF were increased significantly(P < 0. 05)and reduced gradually after smoking cessation(P < 0. 05). SOD and MDA levels increased remarkably in the cigarette exposure group(P <0. 05),and declined gradually after smoking cessation. The levels of IL-8 and TNF-α in BALF and lung tissue ho-mogenate in the smoke exposure group increased significantly( P < 0. 05),and lowered time-dependently after smoking cessation,but not reached to normal level even 12 weeks after smoking cessation. SOD and MDA levels were positively correlated with the cytokine changes. Conclusion Abnormal oxidative stress in the airways caused by cigarette smoking exposure was merely partially reversed after smoking cessation. And the inflammation remains persistent concomitantly.

Objective To observe the effect of puerarin preconditioning on hippocampal CA1 region neuronal injury and further explore its mechanisms. Methods 30 male Sprague-Dawley rats were randomly assigned into sham, model,and puerarin preconditioning ischemia-reperfusion groups. The middle cerebral artery was occluded for 60 min by an intraluminal filament before reperfusion to induce transient focal cerebral ischemia reperfusion rats. Puer-arin preconditioning groups rats received puerarin(100 mg / kg,i. p)1 h before ischemia. The histological changes of hippocampal CA1 region neurons were measured by HE staining on the 5th day after reperfusion. The expressions of Caspase-3 and Caspase-9 proteins in the CA1 region were examined by immunohistochemistry staining. Results The results of HE staining showed that,compared with the model group,puerarin preconditioning significantly re-duced the number of cerebral ischemia induced injury of hippocampal CA1 region neurons(P < 0. 05). Immunohis-tochemistry data showed that the expressions of Caspase-3 and Caspase-9 in the hippocampal CA1 region of puerarin preconditioning group were significantly lower than that of model group(P < 0. 05). Conclusion The results indi-cate that puerarin preconditioning 1 h before ischemia exerts neuroprotective effects on focal cerebral ischemia-reperfusion induced neuronal injury. The neuroprotective mechanisms of puerarin may attribute to inhibiting the ex-pressions of Caspase-3 and Caspase-9 protein.

Yiruo ZHANG ; Kangsheng GU

Acta Universitatis Medicinalis Anhui.2015;(6):829-832.

Objective To investigate the correlation between the expression of CD10,Bcl-6,VEGF with clinical characteristics and the prognosis in the primary gastrointestinal diffuse large B-cell lymphoma. Methods The clini-cal characteristics data of 66 patients with PGI-DLBCL were determined the levels of CD10,Bcl-6 and VEGF by immunohisto-chemical staining. Analyzed their correlation via Kaplan-Meier method and Log-rand test. Results Among those 66 patients,there were 36 cases(54. 5% )of primary stomach,while other 30 cases(45. 5% )were primary intestinal. 39 cases were GCB and 27 cases were non-GCB. The tumor stage and IPI were inverse propor-tion with the prognosis. The median progression-free-survival of GCB was 21. 50 months while non-GCB was 12. 00 months. The positive expression rate of Bcl-6 was 43. 9%(29 / 66)while that of CD10 was 34. 8%(23 / 66)and there were 29 cases(43. 9% )with positive expression of VEGF. Log-rank test revealed there was a positive correc-tion between the positive impression of CD10,Bcl-6 and PFS. On the contrary,the relationship between the ex-pressions of VEGF and PFS was negative. The expressions of CD10,Bcl-6 and VEGF were not correlated with clini-cal features. Cox multivariable analysis showed that the curative effect,the expressions of Bcl-6 and VEGF were in-dependent prognostic factors. Conclusion PGI-DLBCL is a highly invasive and heterogeneous malignancy. The stage of disease,the Hans classification,the level of IPI,the expression of CD10,Bcl-6 and VEGF may play im-portant roles in predicting the curative effect and the prognosis of the disease.
