Fatigue is one of the most common complaints in cancer patients that profoundly affects all aspects of quality of life.However,cancer-related fatigue remains under recognized and poorly treated.This rcview has been conducted with the causes and potential treatments of fatigue in cancer patients.The methods for evaluating fatigue,and possible therapeutic options are also discussed.

Retinal ischemia-reperfusion injury (RIRI) is a common pathological and physiological clinical oculopathy,which can occur in retinal artery and vein occlusion,diabetic retinopathy and acute angle-closure glaucoma.The resulting ischemia can cause cell metabolic dysfunction,serious retinal damage and descending visual function.RIRI is the result of multiple factors.The currently accepted hypotheses mainly include the injury effect of oxygen-derived free radicals,intracellular calcium overload,the action of leucocyte and apoptosis.However the protection and treatment research in the RIRI is limited.The present paper reviews the progression in the drug intervention of RIRI.

Children with plastic bronchitis,characterized by unknown origin,insidious onset,rapid progress,severe symptom and high mortality,is a relatively rare disease.Also,it is difficult to diagnose and treat with plastic bronchitis characterized by marked airway obstruction,via the formation of large gelatinous or rigid airway cast.It is associated with certain diseases including bronchial asthma,cystic fibrosis,accompanied with acute chest syndrome with sickle cell disease,congenital heart disease and bacterial and viral respiratory infection.Clinicians should be aware of this disease,and early bronchoscopy should be intervened.

The appearance of the school of confluence of western medicine and Traditional Chinese Medicine in modern times, the combination of western and Chinese medicine after liberation, and the modernization of traditional Chinese medicine in recent years have exerted great influence on the development of the theory of TCM.

Objective To investigate the clinical significance of DNA haploid analysis for malignant degree and prognosis assessment of breast carcinoma. Methods Highclarity Colourful Pathological Analysis System-1000( HPIAS-1000) was used to analyze the DNA haploid of 120 breast carcinoma patients who had been followed up for more than 5 years. All patients were divided into three groups according to histology. 48 advanced differentiation cases, 44 middle differentiation cases and 28 low differentiation cases. Then DNA haploid analysis was made,that is diploid(2C) ,3 - 4C,aneuploid(AN). Results Except for 3 -4C,there were significant differences betweenⅠandⅡgrade ,ⅡandⅢgrade,ⅠandⅢgrade( P

The pathogenic basis of degenerative retinal diseases is structural and functional abnormality of neuron of retina.The irreversible damage of visual function is the unfortunate results of degenerative retinal diseases,and some effective treating approach to these blindness eye diseases is still in expectation.In recent years,stem cells replacement therapy is increasingly developed and is a prospective way for degenerative retinal diseases.But some formidable challenges for successfully grafting cells to the retina are waiting for further solving,such as migration,survival,and differentiation of the stem cells etc.Recent studies showed that retinal tissue engineering technique may be a good alternation to address all the problems mentioned above.The current advances in stem cell and tissue engineering retina researches,including selectable seed cells,appropriate scaffold materials and transferring method in vivo,are reviewed in this paper.

Idiopathic orbital inflammatory pseudotumor(IOIP) is a common orbital disease.It is a nonspecific inflammatory process,and the etiology is still unknown.IOIP occurs at any position of orbit.The clinical manifestation varies according to the anatomic involvement and the degree of inflammation progress.IOIP can clinically mimic many other orbital diseases,especially serious type of this disease can present similar clinical characteristics as the malignant tumor,so it is comprehensive to make a clinical diagnosis.Currently,the diagnosis of IOIP is allowed based on the differentiation from an exclusion of other diseases by a thorough medical history and clinical manifestations,and then acquire some assistant information by radiologic evaluation and laboratory tests and observe the response to steroid treatment.The final diagnosis still requires histopathological examination.

Objective To assess the feasibility of real-time Bi-Plane in observing normal mitral annular areas in different gestational ages.Methods Routine two-dimensional echocardiography and real-time Bi-Plane were used to observe mitral structure and measure the mitral annular area in 159 fetuses.Pearson correlation analysis was used to evaluate the correlation of the areas with gestational age.Visualization rates and acquisition time were recorded and analyzed statistically.Resuits The mitral annular areas measured by two techniques were both correlated to the gestational age (r=0.71,0.75,both P＜0.05).There were significant differences in visualization rate (x2 =4.375,P=0.036) of mitral annular area and acquisition time (t=6.11,P＜0.05) between routine two-dimensional echocardiography and real-time Bi-Plane.Conclusion Real-time Bi-Plane technique is direct,accurate,convenient and fast in observing mitral prenatally.By using Bi-Plane technique to measure mitral annular area,abnormal morphology changes of mitral valve can be evaluated,so as to provide great application value for clinic.

AIM: To investigate the kinetics of interleukin-6(IL-6) protein and mRNA expressions in the co-culture of rat brain vascular endothelial cells(VECs) with fibrin.METHODS: The IL-6 concentration were measured by rat IL-6 ELISA kit and the IL-6 mRNA was measured by real-time PCR after development an in vitro model of in situ fibrin polymerization on rat brain vascular endothelial cells.RESULTS: Fibrin induced IL-6 expression.The IL-6 antigen concentration increased significantly in 1.0 g/L media group compared to the low dose fibrin group or control media group(P

The effects of cytochalasin D (CD), isolated from Engleromyces goetzii found in our country, on cells of established human esophageal cancer line (ECa-109 cell line) were investigated. It was demonstrated that CD was capable of inhibiting the growth of the cells at the concentration of 0.2?g/ml as indicted by growth curve. The action of CD, however, is reversible, and the cells will gradually grow again normally following the withdrawal of CD. The result also indicated that some proportion of the cells became binucleated or multinucleated after CD treatment. And as the duration of exposure time to CD increased. the multinucleated cells increased in number also. At the concentration of 0.5?g/ml of CD, a phenomenon of extrution of nucleus can be seen among the cells. The nucleus is departed from the cell body but still linked by a fine cytoplasm bridge (Fig. 2). The CD-treated cells bacame enucleated when they subjected to centrifugation following CD treatment. The minicells obtained from enucleation appeared to be normal morphologically with nucleoli but retained only a little cytoplasm around the nucleus. Electromicroscopic observation showed that mitochondria and tonofibrils increased after CD treatment, but we failed to find any changes of microfilaments within the cells.
