Three hundred patients with Graves′ disease (GD) were analysed according to clinical data, which showed a negative correlation between thyroid 131 I turnover and effective half life, suggesting that 131 I turnover is an important parameter for GD therapy of 131 I dose calculation, and a higher cure rate is found in GD patients whose 131 I turnover is less than 1.

Objective To investigate the protective effect of Danhong Injection(DI) on rats ischemia-reperfusion(I/R) injury after kidney transplantation.Methods Ten normal SD rats were allocated into the sham-operation group,and they were only been anesthetized and exposed kidneys for 45 minutes.The allogeneic male SD rats model of kidney transplantation were established.The qualified rats were divided into 3 groups(10 in each group)at random:I/R model group,DI pretreatment group,and DI treatment group.B1ood urea nitrogen(Bun) and creatinine(Cr) levels in each group were determined at the 24th hour after operation.The expression of Bax and Bcl-2 in kidney were quantitatively detected by immunohistochemistry.Apoptotic index was measured by TUNEL method.Results Compared with the sham-operation group,the apoptosis rate(P

Objective To establish human neural stem cells(HNSCs) model for further basic research and clinical application. Methods Cells from human fetal cerebral cortex were collected and cultured with serum free midium and then identified for nestin immunocytochemical staning;The cells were induced to differentiate by 5% fetal bovin serum and identified by neurofilament-200(NF-200) and glial fibrillary acidic protein(GFAP) immunocytochemical staning. Results The harvested cells appeared as clusters in suspension and both NF-200 and GFAP positive cells were observed after induction.After 12 generations of culture,these cells retained the main characteristics of NSCs.Conclusions The HNSCs were harvested from human fetal cerebral cortex and this HNSCs model can be used for futher basic research and clinical applications.;

Celiac disease (CD) is a chronic autoimmune gastrointestinal disorder induced by ingestion of gluten-containing foods.In the past CD was thought prevalent only in Western countries,whereas it has been found common throughout the world and increasing numbers of Chinese patients has been reported recently.However,there are still many deficiencies in management of patients with CD in China and either the diagnosis or the treatment of CD is lacking evidence-based clinical pathway.We report a case of a young woman with CD presenting with chronic diarrhea,abdominal distention,and weight loss,whose outcome was improved by following evidence-based guidelines of medical nutrition therapy.Diagnosis and treatment of the patient was analyzed with review of foreign and domestic literature to provide readers reference of the standardized nutritional intervention of CD.

Fluorescent technology is widely used in many fields due to its high sensitivity. However, the direct quantification of one target analyte in complex system is still difficult to be achieved when using the traditional fluorescent method without any pretreatment separation procedure. This is due to the fact that serious overlapping of fluorescence spectra often occurs, mainly originating from natural interferences in complex sample backgrounds, or the interferents with similar structures to a target analyte, particularly in the simultaneous analysis of multi-components samples. The rapid development of modern analytical instruments and three-way data collection techniques has led to a resurgence of interest in the development of chemomet-rics-based analytical strategies, which might light a new avenue to simple experimentation using“mathematical separation” as a replacement or enhancement of“physical or chemical separation” of uncalibrated background or interferents. These methods can offer a highly attractive property, called“second-order advantage”, which allows for the direct and rapid determination of a single target component or simultaneous determination of multiple target components in complex samples, even in the presence of uncalibrated interferences. The property has been a hotspot in the current chemometric domain, and was successfully employed for many applications, such as pharmaceuticals, biological, food, environmental analysis and so on.

Objective To investigate the inhibitory effect of recombinant LIGHT-Fe gene on the proliferation of human esophageal carcinoma cell line Eea109. Methods LIGHT-Fc expression vector was transfected into human esophageal squamous carcinoma cell line Eca109 by using DOTAP liposomal transfection reagents. The effects of LIGHT-Fc gene on the proliferation of esophageal carcinoma cell line Eca109 in vitro were detected by cell growth curve and MTr assay. Forty-five nude mice were equally divided into Eea109/Wt group, Eca109/neo group and Eca109/LIGHT group. Carcinogenesis and pathological expression of the esophageal carcinoma tissues were observed. Results The expressions of LIGHT receptors were detected in Eca109 cells. The proliferation of Eca109 cells was inhibited after trasfecting LIGHT-Fc gene into Eca109 cells. The numbers of tumors generated in Eea109/Wt group, Eca109/neo group and Eca109/LIGHT group were 12, 11 and 5, with statistical significance between Eca109/LIGHT group and the other two groups (X2 =6.652, 4.821, P <0.05). The result of histopatholagical examination indicated that the tissue necrosis appeared significantly in tumors derived from Eea109/LIGHT cells. Conclusions The growth of esophageal squamous carcinoma cell line Eca109 can be suppressed by LIGHT-Fc gene whether in vitro or in vivo.

Objective To study the effect of Src tyrosine kinase inhibition on subcutaneously transplanted tumor of human lung adenocarcinoma in mice and its mechanism. Methods For the subcutaneously transplanted tumor model, A549 cells or PC-9 cells were inoculated into SCID mice by subcutaneous injection. Immunohistochemistry was used to show the effect of Src tyrosine kinase inhibition on proliferation index (Ki-67 staining) and microvessel density (CD31 staining) of subcutaneously transplanted tumor of human lung adenocarcinoma in mice. Results Subcutaneously transplanted tumor of PC-9 cells was sensitive to src tyrosine kinase inhibitor. There was significant difference between treatment group and control group (P <0.01). There was significant difference between the two treatment group too (P <0.01). Stopping treatment for 1 week, the inhibition rate of tumor growth were 33.19 % and 84.79 % in 10 mg·kg-1·d-1 and 50 mg·kg-1·d-1 treatment group, respectively. The same treatment was less effective to subcutaneous tumors produced by A549 cells. Treatment with 50 mg·kg-1·d-1 Src tyrosine kinase inhibitor significantly reduced the proliferation index of subcutaneously transplanted tumor produced by PC-9 cells (P<0.01) and tended to reduce the proliferation index of subcutaneously transplanted tumor produced by A549 cells (P >0.05). Treatment with 50 mg·kg-1·d-1 Src tyrosine kinase inhibitor significantly reduced micro vascular density in both PC-9 and A549 induced subcutaneous tumors (P <0.05). Conclusion Inhibition of Src tyrosine kinase could suppress the progression of subcutaneously transplanted tumor, not only by the inhibition of cell proliferation of lung adenocarcinoma cells directly, but also by the inhibition of angiogenesis indirectly.

Objective　To make a preliminary analysis of orthokeratology(OK) for treating myopia.Methods　OK lenses were chosen to treat myopia with or without astigmatism according to the myopia characterizations, then changes of their visions, refractions, corneal curvature and eccedtricities after being treated for ld, 1、2、3、4 weeks were observed once every 4weeks and were followed up for 18 months.Results　Significant changes were observed after being treated. Slight myopia: the diopters decreased-2.75D±0.50D,the horizontal meridians flattened 1.64±0.21, the vertical 0.92±0.27 and the eccedtricities declined 0.47±0.11; Middle myopia: the diopters decreased -5.50D±0.75D,the horizontal meridians flattened 2.16±0.45, the vertical 1.61±0.67, and the eccedtricities declined 0.38±0.07; High myopia:the diopters did -6.75D±0.50D,the horizontal did 3.86±0.56, the vertical 2.97±0.67 and the eccedtricities did 0.32±0.10. The predicabilities of slight and middle myopia were superior to high myopia's.Conclusion　Orthokeratology is a non-traumatic therapy and the clinical application should be careful and scientific.
