Objective To investigate the change and role of nitric oxide (NO), nitric oxide synthase (NOS) in serum of children with Epilepsy.Methods The serum NO and NOS levels of 58 epileptic children and 23 healthy children were measured with enzyme linked immunosorbent assay (ELISA). Results The concentrations of the serum NO [( 5.86? 1.21)?mol/ml] and NOS [( 28.26? 8.49)U/ml] in patient group were significantly higher than those in control group [( 3.78? 0.74)?mol/ml,( 17.86? 4.58)U/ml)]( P

ObjectiveTo observe the effect of auricular acupuncture combined with physical therapy on motor function of stroke patients.Methods40 stroke patients were divided randomly into trial group and control group with 20 cases in each group. Patients of trail group were treated with auricular acupuncture combined with physical therapy; cases of control group were treated only with physical therapy. Motor function of all patients were assessed with Fugl-Meyer Assessment (FMA) before and after treatment.ResultsFMA scores of patients of trial group increased significantly compared with that of control group (P<0.01).ConclusionEffect of auricular acupuncture combined with physical therapy is better than that of single physical therapy on motor function of the stroke patients.

Objective To study the quantification of MDR1 and WT1 gene expression in patients with de novo acute myeloid leukemia(AML)and to explore the role of these two genes in clinical drug resistance and their correlation with risk stratification. Methods A real time quantitative reverse transcriptase polymerase chain reaction method was established for detecting MDR1 and WT1 gene expression levels in 63 de novo AML patients.Resuits The expression of WT1 and MDR1 was significantly higher in de novo AML patients than in normal controls (P＜0.001).WT1 levels were significantly correlated with corresponding levels of MDR1 gene in de novo AML patients(P=0.004).Expression levels of WT1 and MDR1 gene were not associated with FAB subtype and risk stratication(P＞0.05).AML patients with FLT3-ITD mutations had a significantly higher WT1 expression level as compared to with those without(P＜0.05),on the contrary MDR1 expression was not associated with FLT3-ITD mutations(P＞0.05).Patients with co-expression of high levels of WT1 and MDR1 had a significantly lower complete remission rate after induction therapy than those with low levels(P＜0.05).Conclusion There is a positive correlation between MDR1 gene expression and WT1 gene expression in AML.Quantification of the two gene expression together is more effective for judgement of prognosis in AML.

Objective:To evaluate the effect of Candida albicans ( C. albicans) hyphae on autophagic flux in murine bone marrow-derived macrophages (BMDM) . Methods:BMDM were in vitro stimulated with C. albicans hyphae for 0.5, 4 and 12 hours, and the 0-hour group treated without hyphae served as a control. Western blot analysis was performed to detect the conversion of microtubule-associated protein 1 light chain 3 (LC3) -Ⅰto LC3-Ⅱ, and determine the expression of phosphorylated mechanistic target of rapamycin (p-mTOR) at each time point. Some BMDM were divided into several groups: control group receiving no treatment, hyphae group treated with C. albicans hyphae, lysosomal inhibitor groups treated with different lysosomal inhibitors, including E-64d (a cysteine proteinase inhibitor) + pepstatin (a pepsin inhibitor) , bafilomycin-A1 (BAF-A1) , ammonium chloride and chloroquine, and hyphae combined with lysosomal inhibitor groups treated with lysosomal inhibitors immediately followed by C. albicans hyphae. After 4- or 12-hour treatment, the effect of C. albicans hyphae on basal autophagic flux in murine BMDM was evaluated. Statistical analysis was carried out by using unpaired t test, factorial design analysis of variance and least significant difference- t test. Results:After 0.5-, 4- and 12-hour in vitro treatment with C. albicans hyphae, the conversion of LC3-Ⅰ to LC3-Ⅱ significantly increased in murine BMDM (1.254±0.118, 1.629±0.391, 1.598±0.379, respectively) compared with the 0-hour group (0.983±0.030; t=3.875, 2.856, 2.804, respectively, all P< 0.05) , while there was no significant difference in the protein expression of p-mTOR among the 0-, 0.5-, 4- and 12-hour groups. After 4- and 12-hour in vitro treatment with C. albicans hyphae combined with lysosomal inhibitors E-64d and pepstatin, the accumulation level of LC3-Ⅱ significantly increased in BMDM compared with those treated with E-64d and pepstatin alone ( t=3.691, 6.648, respectively, both P< 0.05) . Compared with the corresponding lysosomal inhibitor groups, the accumulation level of LC3-Ⅱsignificantly increased in BMDM treated with C. albicans hyphae combined with BAF-A1, ammonium chloride or chloroquine for 4 and 12 hours (all P< 0.05) . Conclusion:In vitro treatment with C. albicans hyphae can increase the conversion of LC3-Ⅰto LC3-Ⅱ in the basal autophagic flux in murine BMDM.

Objective To compare the chemical components among Rhizoma Alismatis of different specifications. Methods Rhizoma Alismatis of 8 different weights were chosen, and then contents of 23-acetate alisol B were determined by HPLC, and infrared spectrometry fingerprint was determined by Fourier transform infrared spectroscopy. Results The contents of 23-acetate alisol B in Rhizoma Alismatis of 8 different specifications were over 0.06%, and had no relation with specification of Rhizoma Alismatis (P>0.05). The similarities of infrared spectrometry fingerprint were above 0.9. Conclusion The chemical components among Rhizoma Alismatis of different specifications were basically the same. Contents of 23-acetate alisol B of Rhizoma Alismatis of 8 different specifications conformed to regulation of China Pharmacopoeia.

Objective To explore the clinical effect of sitagliptin combined insulin compared to those patients whose sugars were not well controlled by insulin alone.Methods The eighty type 2 Diabetes patients whose BMI≥24 kg/m2 and used insulin alone were randomly divided into sitagliptin combined insulin group (40 cases) who were given sitagliptin 100mg/d allied with insulin,an insulin group (40 cases) who were given insulin alone.After 12 weeks,the change of body mass index (BMI),fasting plasma glucose (FPG),2 h postprandial blood glucose (2 h PBG),glycosylated hemoglobin (HbA1 c),β-cell function index(HOMA-β),insulin resistance index (HOMA-IR),insulin quantities,and hypoglycemia rates were observed in two groups.Results Compared with pretherapy,the levels of FPG,2 h BG,HbAlc,HOMA-IR,and hypoglycemia rates were significantly decreased (P ＜0.05) ; BMI was increased in insulin group,while was not increased in sitagliptin combined insulin group.After the treatment,the insulin quantities were decreased in the combined group while increased in the control group (P ＜ 0.05).Conclusions Sitagliptin combined insulin can effectively control glucose levels of type 2 diabetes patients,decrease the insulin quantities and the risk of hypoglycemia,and does not increase the weight.

Objective To observe the effects of herbal compound in reinforcing the kidney for activating blood and arousing consciousness(HCRAA) on the ABR threshold and the expression of neurotrophic factor 3(NT-3) of the cochlea of gentamicin (GM)-induced ototoxic mice.Methods 40 mice were randomly divided into normal group,model group,and high,middle and low concentration HCRAA groups.Normal group received no treatment.The model group and the HCRAA groups were intraperitoneally injected with GM 100mg/kg per day for consecutive 15 days.At the same time,the model group and the HCRAA groups respectively receiveded normal saline and high,middle and low concentration Chinese medical formula decoction at the same dosage by garage for consecutive 20 days.After the experiment,the mice were tested ABR.The expression of NT-3 of the cochlea in mice was detected by western blot.Results HCRAA at high and middle concentration reduced the GM elevated ABR threshold(P＜0.01),and increased the expression of NT-3 in the cochlea(P＜0.01).Conclusion HCRAA may effectively reduce the elevated ABR threshold induced by gentamycin by protecting GM damaged cochlear hair cell and neurons and increasing the expression of NT-3 in the cochlea.
