Journal of International Oncology 2011;38(9):717-720
Objective To investigate the expression and clinical significance of fibroblast growth factor-2 (FGF-2) and human teclomerase reverse transcriptase (hTERT) in non-small cell lung cancer (NSCLC) tissues and analyze the correlation between them.Methods The expression of FGF-2 and hTERT were detected by immunohistochemistry in 90 NSCLC tissues and 20 non-lung carcinoma tissues.The correlation between the expression and clinicopathological features was also analyzed.Results The positive expressions of FGF-2(66.7% ) and hTERT (75.6%) in NSCLC tissues were significantly higher than that in nonlung carcinoma tissues (15% and 20%,respectively),P <0.01.The expression of FGF-2 and hTERT were significantly related to TNM stages and lymph node metastasis (P < 0.01 ),but not to histological types,sex and age of NSCLC patients ( P > 0.05 ).A positive correlation was found between the expressions of FGF-2 and hTERT in NSCLC(P < 0.01 ).Conclusion The expression of FGF-2 and hTERT in NSCLC,which can be regarded as important references for prognosis of NSCLC,play important roles in the initiation and development of NSCLC.

Objective To observe age-dependent feature of damage of hippocampus to different maturational stages rats after kindling repeated seizures.Methods The effects of 5 daily pentylenetetrazol-induced convulsions in different rats beginning at postnatal day 10,20,60(P10,P20,P60)were evaluated.In the 3 groups,Thionin staining method was utilized to observe morphological changes and cell counting of dentate granule cells,CA3,CA1,and hilar neurons.Timm's method of silver sulfide staining was adopted to observe the mossy fiber sprouting.Results 1.Cell counting of CA1,CA3 and hilar neurons in P10 and P20 groups demonstrated no differences from controls in rats,whereas P60 with daily seizures had a significant decrease in CA1,CA3 neurons(8.22?1.88,5.62?1.68 vs 6.31?1.50,3.62?1.40)(t=2.246,2.587 Pa

Oral fluid resuscitation in early period of hypovolemic shock is an important measure in the treatment of casualties in the battlefield as well as in mass casualties in lieu of the means of establishing a venous line. The main tasks in the study of oral rehydration resuscitation are the proposition of appropriate prescriptions of the liquids to be given and methods of administration on the basis of a clear elucidation of the mechanism underlying the function of the digestive system in regard to transportation and absorption of the given ingredients. The aim of the study is to fully replenish maximal amount of fluid containing glucose and electrolytes in a convenient, expeditious, and effective way in a minimal span of time, in order to increase circulating blood volume. At the same time, ischemia and tolerance to oral fluids of the gastro-intestinal tract should be improved, electrolyte imbalance and incidence of secondary infection should be alleviated, and finally hypovolemic shock is corrected, so that the victim is kept alive and prepared for further definitive surgical intervention.

Purpose:To evaluate the feasibility of irradiat ion to the metastatic retroperitoneal lymph nodes using three-dimensional confo rmal radiotherapy (3-DCRT) and to assess the irradiation side effects. Methods:From Jun. 1997 to Sep. 2000, 52 patients of metastatic retroperitoneal lymph nodes were treated with 3-DCRT.These patients had receive d radical therapy for their primary tumors. 50 of them had been proved by pathol ogical examination. Radiotherapy was designed by Elekta company’s 3-D treatmen t plan. Dose volume histography (DVH) was used to verify and optimize the radiat ion plan. Using 5~6 conformal portals,the total irradiation dose was 40 Gy an d delivered at 4~5Gy per fraction every other day,to a total of 8~10 fractions in 16~20 days. The immediate responses and side effects were evaluated accordi ng to the WHO and RTOG criterion system. Results:According to Karnofsky criterion system the median scor e was raised 21.3. Three months after irradiation, the complete ,partial and tot al response rates were 38.6%(27/70), 54.3%(38/70)and 92.9%(65/70),respect ively. The early response was related to the target volume and pathological clas sification. The smaller the target volume, the better the response(? 2 = 1 5.211,P=0.004).The anaplastic carcinoma cases had better results than the squamous carcinomas and adenocarcinomas(? 2 =13.455,P=0.009).The 1- ,2- and 3- year survival rates were 59.6%(31/52)、23.1%(12/52)and 9.6%(5/ 52),respectively. Conclusions:Three dimensional conformal radiotherapy can be con sidered as an effective and feasible approach for the treatment of metastatic r etroperitoneal lymph nodes,and no serious complications were observed.

Objective To analyse the pathologic changes and MRI appearances of mitrial atresia (MA). Methods MRI appearances of 5 cases with MA confirmed by operation were reviewed and compared with angiocardiography (CAG). Results MRI demonstrated the pathologic characteristics of three types of MA according to the traditional classification:biventricular hearts with imperforate mitral valve (1 case),univentricular heart of right ventricular type with absent left atrioventricular connection (3 cases) and univentricular heart of left ventricular type with imperforate mitral valve (1 case).MRI still provided anatomic information of associated anomalies including mainly aneurysms of atrial septum (1 case),total anomalous pulmonary venous drainge into superior vena cava (1 case),absent left pulmonary artery (1 case) and pulmonary stenosis (4 cases). The right atrial and(or) ventricular angiocardiograms in the 5 cases could not display the anatomic morphology of the malformation,with exception of one case only. Conclusion MRI is valuable in diagnosis of MA.

Objective Depression is a mood disorder that causes a persistent feeling of sadness,with high morbidity rates and great social impairment.Increasingly studies show the abnormalities of brain networks.We summarized the results of resting state functional magnetic resonance imaging study of depression,and demonstrated the neural loops mechanism from neuroimaing perspective.Methods The key words depression, resting state and network were searched in PubMed,CNKI and Wan Fang databases from January 2000 to December 2014.The nodes of depression related network and the alterations of cortex resting-state networks were summarized.Results 24 studies focusing on resting state network of depression were identified.40 studies based on ROI (region of interest) analysis,which included amygdala,frontal lobe,pregenual anterior cingulate cortex and cerebellum.The functional connectivity of ROIs were calculated and compared between groups.8 studies based on ICA (independent component analysis),the resting state networks were extracted and compared between groups.Two based on graph theory,the functional connectivity of whole brain were analyzed and compared.Conclusion There are abnormalities of functional connectivity among limbic system-thalamus-frontal cortex,and the changes of functional connectivity were associated with clinical symptom and drug efficacy of depression.
