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 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.

Objective:To observe the curative effect of potassium magnesium aspartate in the auxiliary treatment of ventricular pre -mature beat.Methods:Totally 70 patients with ventricular premature beat were randomly divided into the observation group (36 ca-ses) and the control group (34 cases).The patients were treated with metoprolol , and the patients in the observation group was treated with potassium magnesium aspartate as the auxiliary therapy , and the patients in the control group were treated with potassium chloride sustained release tablets as the adjuvant treatment .After 3-week continuous treatment , the changes of serum potassium , serum creatine kinase, creatine kinase, lactate dehydrogenase and ECG were observed in the two groups .The therapeutic effects and adverse drug re-actions were compared between the two groups .Results: After the treatment , the levels of serum potassium , serum creatine kinase isoenzyme, creatine kinase and lactate dehydrogenase were significantly improved when compared with those before the treatment (P<0.05), and the improvement of the observation group were significantly better than that of the control group (P<0.05).After the treatment, the heart rate and PR interval in the two groups were significantly improved (P<0.05), and there was no significant differ-ences between the two groups (P>0.05).The total effective rate of the observation group was 91.67%, which was higher than that of the control group (82.35%, P<0.05).The incidence of adverse drug reactions in the observation group was significantly lower than that in the control group (P<0.05).Conclusion:Potassium magnesium aspartate in the adjuvant treatment of ventricular premature beat can significantly improve the levels of serum potassium and serum myocardial enzyme and heart rate and ECG of the patients , and the efficacy and the incidence of adverse drug reactions are better than those of potassium chloride sustained -release tablets in the adju-vant treatment .

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.

To explore the mode of matrix and cell injury of articular cartilage subjected to high stress mechanical loads with a low rate of loading. Loads characterized by a constant stress rate of 0.26MPa/s to a peak stress between 2MPa and 11MPa being applied to the adult bovine articular cartilage explants was designated as the test groups. No mechanical loads were applied to the control group. All the explants were maintained in culture for the next few days after loads. The spatial patterns and severity of chondrocyte injury were determined using fluorescein diacetate and propidium iodide. Matrix damages were assessed by inspection of the microstructure of the collagen fiber network under SEM. When the peak stress was 5MPa and higher, the rate of cell death in the explants of test groups was significantly greater compared with controls, and the greater peak stress applied, the higher percentage of dead versus total cells was documented, and a more diffuse distribution of dead cells was observed. When the peak stress reached 9MPa, cell death involving full depth of the cartilage was observed in test groups . Damages to the collagen fiber network were not observed both in test and control groups. The results indicated that high stress mechanical loads with a low rate of loading resulted in more severe chonrocytes damage rather than collapse of collagen fiber network.

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.
