Primitive neuroectodermal tumor (PNET) is a kind of malignant tumor, which most often affects children and adolescents. The incidence of PNET has risen recently. PNET has low early diagnosis rate and poor treatment effect. With the application of RT-PCR and FISH in pathological diagnosis, and MRI and PET-CT in imageological diagnosis, as well as the implementation of target treatment and multidisciplinary integrated treatment concept in the treatment, the pathogenesis, diagnosis technology and treatment means of of PNET have made remarkable progress.

The Viet Duc Hospital found 6 cases of the postoperative left gauze by ultrasound during 1997-1998. The diagnosis based on the clinical symptoms (infectious sign), operative history, position and size of foreign body. The foreign bodies found earliest in the 20th days and longest in the 4th years after an operation. The form, size and structure of the foreign bodies have not been changed through the round of examination.

Cancer is one of the most dangerous diseases that threaten human health.The early diagnosis individual treatment and accurate judgement of recurrence play important roles in prognosis.microRNA (miRNA) is a class of small fragments of RNA molecules which has the ability to regulate the gene expression.In recent years,some researchers have begun to focus on it.Studies have shown that the great stability of circulating miRNA in body fluid,as well as the specificity in many types of cancer,which may be important for the diagnosis and prognosis of cancer patients.In this review,the advantages and limitations of circulating miRNA as a new biomarker of cancer are birfly summarized.

Objective To investigate the relationship between hypothyroidism condition and renal function in diabetic nephropathy (DN) patients via measuring the hypothyroidism status of patients at different renal function stages of DN.Meanwhile,the influence of hemadialysis on thyroid function was also evaluated to pursue better treatment measures for the patients with diabetic nephropathy complicated with hypothyroidism.Observe the influence of hemadialysis in values of thyroid function,and discuss the better therapy of diabetic nephropathy with hypothyroidism.Methods FT3,FrT4,TSH3 were tested by chemiluminescence immunoassay in 125 cases of DN for January 2008 to December 2010,and SCr、BUN were tested at the same time.Then investagated the changes of thyroid function items of DN with uremia patients after hemadialysis.Analyze the data statistically.Results SCr,BUN of DN group were negatively co-related to FT3,FrT4 ( r =- 0.65,- 0.46,-0.76,- 0.56,P ＜ 0.05 ) ; But not co-related to TSH3 ( P ＞ 0.05 ).The changes of thyroid function items,namely FT3,FrT4,TSH3 of DN with uremia patients after hemadialysis was not statistically significant.Conclusion SCr,BUN were negatively correlated to FT3,FrT4,but there was no relation between SCr,BUN and TSH3.Hemadialysis therapy is not beneficial for the hypothyroidism in DN patients.

Objective To establish a HPLC method for determining of the content of palmatine hydrochloride in Fuke Qianjin Tablets. Methods HPLC was performed on Shimadzu-C18 column. The mobile phase consisted of 0.05 mol·L-1 sodium acid phosphate (pH=3, adjusted by phosphoric acid)-acetonitrile (72 : 28). The detection wavelength was at 265 nm. Results The linear correlation was in the range of 0. 051 μg～0. 255 μg(r=0. 999 9). The average recovery was 100. 04 %, and RSD=1.03 % (n=5). Conclusion The method is accurate and specific.

Vascular endothelial growth factor (VEGF) family consists of a group of secreted dimeric glycoprotein with a cysteine knot motif of regularly spaced eight cysteine residues,which plays a key role in vasculogenesis,angiogenesis and lymphangiogenesis via their special receptors.VEGF-A,one of VEGF families,is essential for vasculogenesis and angiogenesis.So inhibition of VEGF is available in the treatment of cancer and some diseases of pathological angiogenesis.Some studies imply that VEGF receptor-2 (VEGFR-2)is expressed in some nonvascular tissue and exerts an important role in the differentiation and survival of the cells.The expressions of VEGF and VEGFR-2 in lens epithelial cells(LECs) can be detected in the formation of lens vescle in embryo stage to adult.VEGF secreted by lens itself is concerned with the differentiation and development of lens via autocrine and paracrine.

Clinical efficacy scale of traditional Chinese medicine (TCM) should be built according to the characteristics of TCM, scientific demand, and demonstrated by practice. This paper provides some considerations of the scale.
