Objective To investigate the roles of differentiation and proliferation related proteins in neural stem cells (NSCs) in rats treated with L monosodium glutamate (MSG). Methods Tissue proteins were extracted from the rat forebrain. Western blotting was used to investigate the changes of differentiation and proliferation related proteins in NSCs in rats treated with MSG. Results Compared with those in rats of the normal control group, the related proteins (Notch1, hes5, Mash1, and NeuroD) in NSCs were significantly decreased in MSG rats at 30 and 60 d, especially for Notch1 and hes5 ( P

Objective To explore the changes of differentiation and proliferation of neural stem cells in rats treated with corticosterone (CORT). Methods Adult SD rats were administered with CORT (10 mg?kg -1 ?d -1 ) by consecutive subcutaneous injection for 14 days. Single and double immunohistochemical stainings were used to identify the neural stem cells and differentiated neural cells in adult rats. Results Compared with that in the normal control group, the number of BrdU immunohistofluorescence positive cells and BrdU+NF200, BrdU+NeuroD, BrdU+GFAP double immunostaining positive cells in the cerebral cortex, hippocampus, and hypothalamus were markedly decreased ( P

Objective To evaluate the days of hospitalization of acute transverse myelitis and its influencing factors.Methods File's of 158 patients with acute transverse myelitis as the first diagnosis in Feicheng Mining Centre Hospital were analyzed retrospectively.Access to the original medical records through the medical record number, and supplemented information, mainly including demographic data, neurological function defect degree, complications and complications.Results Hospitalization time was 4-41 d, an average of (17±6) d,including 23 patients hospitalized time ≤ 10 d(14.56％), 83 cases were ＞ 10-＜20 d(52.53％), 52 cases was≥20 d(32.91％).Age and Neurological score comparative differences are statistically significant (F=60.90,8.68, P＜0.05).Payment method, deep vein thrombosis, comparative differences were statistically significant(x2 =20.04, 14.27, 12.17,9.37,7.05;P＜0.05).There were ralationship between acute transverse myelitis with age, neurological score, payment (OR =1.140, 0.500,83.930,0.041;P＜ 0.005).Conclusion The degree of neurologic impairment is the most important influencing factors of acute transverse myelitis.Controlling hospital infection, preventing deep vein thrombosis, strengthening medical insurance management, are the effective ways to shorten the days of hospitalization of acute transverse myelitis.

There is an evidence that mitochondrial cytochrome C has dual functions in controlling both cellular energetic metabolism and apoptosis. Once released, cytochrome C, in interaction with apoptotic protease activating factors (Apaf 1), initiates the activation of the execution caspases that lead to the subsequent apoptosis. Release of cytochrome C is the result of a perturbation of mitochondrial membrane permeability. Anti apoptotic Bcl 2 family proteins function as gatekeepers to prevent the release of cytochrome C. In addition to cytochrome C, mitochondria release other apoptogenic proteins including apoptosis inducing factor (AIF) during apoptosis. These two pathways may work together to induce complete apoptosis. After transient cerebral ischemia, the release of cytochrome C occurs from mitochondria, preceding DNA fragmentation.

The pathogenesis of cancer and related treatment were discussed.With regard to cancer,WANG emphasized the vital qi tangled theory,evil dominant theory,theory of blood stasis resulting tumor,non-blood stasis theory,sputum and toxin harm theory.As for cancer treatment,method of expelling stagnation,regulating qi,eliminating phlegm,softening hard mass and detoxicating should be used according to the specific syndrome.

Objective To investigate the relation between expression of MMP-9 and RECK in laryngeal carcinoma and it′s clinical characteristics and to explore the biological action of laryngeal tumor. Methods 38 laryngeal squamous cell carcinoma (LSCC)specimens and normal mucosa were examined for the expression level of MMP-9 and RECK protein by IHC method ( PV9000) and RT-PCR was employed to measure the expression of MMP-9 and RECK mRNA. Ten laryngeal papilloma were used for controls. Results The expression level of MMP-9 protein in carcinoma of larynx was 92.11%,which was significantly higher than that of the adjacent tissues (P

The lymphatic vessel is one of the earliest routes for systemic neoplastic metastasis. But reports on research of the lymphatic vessel have been few compared to the study for tumor vessels. In the past few years,along with advances in understanding about the construction features of the lymphatic system,work has been done to determine the anatomic fundamentals of lymphatic metastasis. Many new specifi c markers of the lymphatic endothelium had been reported, which is useful to differentiate lymphatic vessels from capillary vessels. The lymphatic vessels are usually found in the animal tumor models, human tumors and peritumoral tissues. Furthermore, the molecular mechanism of lymph-angiogenesis has been discovered, which provide effective targets for anti-lymphatic metastasis of malignant tumors, make optimization of individualized treatment strategy possible to restrain lymph-angiogenesis of malignant tumors and so it could benefi t in improving patients' prognosis and survival.

Micro-ribonucleic acids (miRNAs) are endogenous single-stranded small non-coding RNAs. miRNAs bind to a com-plementary site in the 3' untranslated region of their target mRNAs through canonical base pairing, which can direct the degradation or translational repression of these transcripts. Thus, miRNAs can effectively silence the protein expression of target genes post-transcrip-tionally. miRNAs may also regulate the expression of oncogenes and tumor suppressor genes and could be involved in almost all known hallmarks of cancinogenesis. In this paper, we discuss the following in detail:(1) biogenesis and main functions of cellular miR-NAs, (2) stability and detectability of exosomal miRNAs in biological fluids;and (3) feasibility of miRNAs as a potential new class of biomarkers derived from urinary exosome in the malignancy of urinary system. Finally, we summarize studies on urinary exosomal miRNAs as potential biomarkers of prostate, bladder, and kidney cancers.

Objective To investigate the clinical effect of Itopride and esomeprazole combining with deanxit in treating functional dyspepsia ( FD) .Methods Sixty-two patients meeting Rome Ⅲcriterion were randomly divided into the therapy groups which were treated with Itopride and esomeprazole combining with deanxit and the control groups which were treated with Itopride and esomeprazole for 4 weeks respectively .Symptom scoring was done before and after the treatment .Results The symptoms were remarkably improved , there was significant difference in the therapeutic effect between the two groups (P<0.05).The total efficiency was more obvious in the therapy group . Conclusion Itopride and esomeprazole combining with deanxit can produce an effect on the treatment of FD .Itopride and esomeprazole combining with deanxit has better clinical effect than Itopride and esomeprazole on the treatment of FD.
