Dopa-responsive dystonia(DRD) is a clinical syndrome characterized by childhood dystonia and dramatic and sustained response to low-dose levodopa.The deficiency of any link in dopamine synthesis pathway can lead to DRD that is caused by TH gene mutation and is autosomal recessive, which results in the reduction of tyrosine hydroxylase(TH) synthesis and extensive deficiency of dopamine and catecholamine.However, DRD presents atypical clinical manifestations.Mild patients mainly present with dystonia.Some of them might progressively develop into spastic paraplegia and some may have parkinsonian features.Most of them display good response to levodopa.Severe patients present with progressively complex infantile encephalopathy, and badly response to levodopa and remnant intellectual development problems.Most of them manifest with declining homovanillic acid(HVA) in cerebrospinal fluid.However, due to the noncharacteristic clinical course and nonspecific laboratory tests of TH DRD, gene detection still is the only reliable criterion of diagnosis so far.Low-dose levodopa is effective to most mild patients and can improve symptoms to severe patients to some extent.

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.

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 investigate the effect of Astragalus and chemotherapy on the expression of vascular endothelial growth factor(VEGF)in non-small cell lung cancer(NSCLC), microvessel density(MVD)and immune function.Methods 92 patients with NSCLC were divided into the study group and the control group, 46 cases in each group.Both groups were treated with neoadjuvant chemotherapy and operation, and the study group was treated with astragalus polysaccharide.The expression of VEGF in cancer tissues, MVD and immune function were compared between the two groups.The short-term and long-term curative effect and the incidence of adverse reactions were recorded.Results After treatment, positive rates of VEGF, MVD and blood CD8+ were significantly decreased in two groups (P<0.05), showing study groupcontrol group (P<0.05).There were no significant differences between the two groups in short-term curative effect and 5 year survival rates.The incidence rates of side effects in the study group were significantly lower than those in the control group (P<0.05).Conclusion Adjuvant chemotherapy combined with intravenous infusion of Astragalus Polysaccharide can improve MVD, the expression of VEGF and immune function in patients with NSCLC.

Tumor markers for early diagnosis of cancer is an important auxiliary mean,which for early tumor detection,monitoring and for judging curative effect of treatment regimens play important role.Clinical method for early diagnosis on ovarian cancer is the detection of serum CA125,however,its precision and specificity for early diagnosis are not enough.It has been found that in the development period of the patients with ovarian cancer,SMRP and CA125 is co-expression.This article reviews the value of serum mesothelin on diagnosis of epithelial ovarian cancer to provide reference on early diagnosis and treatment.

Objective To explore the application value of ATP bioluminescence in assaying the cleaning quality of uterine suction.Methods According to the principle of random,we selected 120 uterine suction tube after use.60 used tubes in A group were given water immersion + high-pressure water jets wash + dry method,60 used tubes in B group were given alkaline cleaning solution soak + ultrasonic + high-pressure water washing + manual scrub + drying method.The quality of suction tube was initially tested with the visual method after cleaning,Straw inside the top cavity,2.5cm at inside straw joint and the front of straw outer wall,10cm at suction cavity wall,before and after cleaning the residues of bacteria were assayed with the ATP bioluminescence and bacteria counting method for parallel comparison.Results After cleaning drying program,the RLU of two groups in suction head internal top,2.5cm at inside straw joint,the front of straw outer wall,10cm at suction cavity wall had significant differences (t =26.81,29.13,7.14,55.74,P ＜ 0.01).The cleaning effect of B group was better than A group..Bacteria counting method was used to detect pathogenic microorganism that was not detected.The qualified rate of cleaning at four parts was as following:group A:70.0％,85.0％,93.3％,93.3％.B group:95.0％,98.3％,100.0％,100.0％,and the qualified rate of group B was significantly higher than group A (x2 =12.99,6.98,4.14,4.14,all P ＜ 0.05).Conclusion ATP bioluminescence method can dynamically rapid detect the bacteria before and after intrauterine suction cleaning residues,can be viewed as an effective method to detect quality of uterine suction cleaning.
