Objective To evaluate the efficacy and safety of combined intrapleural therapy with bevacizumab and cisplatin in controlling malignant pleural effusion(MPE)caused by non?small cell lung cancer(NSCLC). Methods A total of 63 NSCLC study subjects with MPE were randomly assigned to one of two groups(A and B). Group A(bevacizumab,n=32)received intrapleural bevacizumab(5 mg/kg)with cisplatin(40 mg/m2) therapy once a week for a total of three cycles. Group B(cisplatin,n=31)received intrapleural cisplatin therapy alone with the same dose and cycle. Pleural fluid was collected from both groups prior to and after treatment. The levels of VEGF in the pleural fluid were determined by ELISA. The cura?tive effect and adverse reaction were observed and follow?up was conducted. Results In 63 evaluable study subjects,the curative efficacy in the be?vacizumab group was significantly higher than that found in the cisplatin group(84.3%vs 61.3%,respectively,P<0.05). But the overall survival (OS)of the two groups showed no statistically significant difference(13.0 months vs 12.0 months,P>0.05). After treatment,The VEGF levels in the MPE were significantly decreased in both groups. In the bevacizumab group,the levels of VEGF in the pleural fluid were significantly lower com?pared to those of the cisplatin group after treatment,showing greater efficacy(P<0.05). The VEGF levels of the two groups whose treatment was in?valid had no statistically significant difference(P=0.079). There was no significant difference in gradeⅢ/Ⅳadverse events between the two groups. All procedures were well tolerated by the patients. Conclusion Combined intrapleural therapy with bevacizumab and cisplatin was effective and safe in managing NSCLC?mediated MPE. The patients showed high tolerance to the therapy. For prediction of local treatment efficacy of bevaci?zumab using the VEGF expression levels in MPE,further research was needed.

Objective To investigate the clinic value of procalcitonin( PCT)and c-reactive protein ( CRP)in differential diagnosis for febrile diseases. Methods One hundred and forty patients with febrile diseases in May 2009 to February 2014 in the No. 309th Hospital of People Liberation Army were investigated and analyzed retrospectively. Based on discharge diagnosis,patients were divided into bacterial infection group( n=58),non-bacterial infection group(n=47)and rheumatic diseases group(n=35),another 40 healthy people were served as the control group. Serum PCT and CRP were detected and compared in four groups. One month after backing to normal temperature in all the patients,detected serum PCT and CRP again. Results Serum PCT and CRP level in bacterial infection group,non-bacterial infection group,rheumatic diseases group and control group were(5. 18 ± 1. 92)and(0. 45 ± 0. 22),(0. 34 ± 0. 13)and(0. 16 ± 0. 05)μg/L,(25. 31 ± 4. 24), (1. 94 ± 0. 37 ),( 62. 32 ± 15. 10 ) and( 1. 30 ± 0. 04 ) mg/L respectively. Serum PCT and CRP level in bacterial infection group were significantly higher than that in control group(P﹤0. 01). Even though serum PCT and CRP level in non-bacterial group slightly higher than that of healthy control group,there was no statistical difference(P﹥0. 05). Serum PCT and CRP level in bacterial infection group were significantly higher than that of non-bacterial infection group( P ﹤0. 01 ). Serum CRP level in rheumatic diseases group was significantly higher than that of healthy control group( P﹤0. 01),while PCT level only slightly higher compared with healthy control group(P﹥0. 05). One month after backing to normal temperature in all the patients,serum PCT and CRP level in bacterial infection group reduced significantly compared with that of febrile period( P ﹤0. 01). Serum PCT and CRP level in non-bacterial infection group were no significant change( P﹥0. 05 ),and serum CRP level in rheumatic diseases group reduced significantly( P﹤0. 01 ),while serum PCT were no significant change(P﹥0. 05). Conclusion Serum PCT combined with CRP might be of great importance in the differential diagnosis for febrile diseases.

Objective To analyze the onset time rule of spontaneous pneumothorax ,and investigate the influence of climatic factors such as atmo-spheric pressure,wind speed,etc. on the onset of spontaneous pneumothorax. Methods Five hundred and ninety-three patients of spontaneous pneumothorax in Cenral Hospital Affiliated to Shenyang Medical College were enrolled for this study between January 1,2011 and December 31, 2015. The data of the average daily atmosphere pressure and wind speed in five years were recorded. The relationship between the onset of sponta-neous pneumothorax and the change of the atmosphere pressure and wind speed was analyzed. Results The incidence of spontaneous pneumotho-rax in Shenyang area was obvious seasonal. Primary spontaneous pneumothorax episodes were observed mostly in spring and in March and April;Second spontaneous pneumothorax episodes were observed mostly in winter and in November and December. The difference in mean atmospheric pressure was 0.6 hPa lower than on days in which no spontaneous pneumothorax occurred. This difference was statistically significant(P=0.015). We observed significantly higher average wind speed on days with SP versus days without(9.46±6.33 m/s vs 7.11±5.47 m/s,P<0.001). Conclu-sion Spontaneous pneumothorax has obvious aggregation of onset time. A sharp drop in atmospheric pressure and increases in wind speed has im-portant influence on the incidence of spontaneous pneumothorax.

Granolocyte-macrophage clony-stimulating factor (GM-CSF) is a heamato-poietic growth factors involved in the generation of granulocytes and macrophages. Recent studies have suggested that the expression of GM-CSF increases following cerebral ischemia in the nervous system, indicating that GM-CSF may play an important role in the neuroprotection after ischemia. M-CSF protects neurons mainly through anti-apoptosis, promoting collateral circulation, and inhibiting energy consumption.

Objective To study the security of low dose and half-body irradiation by 60Co ?-rays as a new method of clinical radiotherapy.Methods The simulated manikin was used to simulate human body and two radiation modalities of facing and backing on radioactive source were adopted.Half-body irradiation was done by 60Co ?-rays with doses of 9,10 and 11 cGy.The exposure dose of every layer and important target organs in the simulated manikin were detected,and the security of low dose and half-body irradiation as a therapeutic method was evaluated.Results The exposure dose of every layer and sensitive organs were all within safety margin,when simulated manikin facing or backing on the radioactive source was irradiated by 60Co ?-rays with doses of 9,10 and 11 cGy.Further,the exposure dose of sensitive organs in the simulated manikin backing on the radioactive source was lower than that in those facing the radioacive source.Conclusion The method of low dose and half-body irradiation as a radiotherapeutic method is safe and feasible and the radiation modality of backing on the radioactive source is more safe.
