Objective To detect the level of nitric oxide (NO) and amino acids in cerebrospinal fluid and serum of epilepsy children in different time. Methods The level of NO and amino acids in cerebrospinal fluid and serum of epilepsy children in different time were determined with nitrate reductase and high performance liquid chromatography (HPLC) with fluorimetric detection. Results The level of NO2 - increased 30 min, 60 min, 120 min after seizures (P<0.01), but dropped to normal 180 min after seizures (P>0.05). The level of glutamate (Glu) significantly increased in all epilepsy groups (P<0.05). The level of glycine (Gly) dropped gradually in all epilepsy groups (P<0.05).Conclusion NO may participate in the generation of seizures and the injury process to brain. The imbalance between excitatory and inhibitory amino acids may play an important role in the pathogenesis of epilepsy. The toxicity of excitatory amino acids may be the main injury to the brain.

To set standards for histomorphological studies on Lysimachia fortunei, an efficacious and widely applied folk medicine in this study, in order to develop its resources. Its species were identified by observing plant morphology and herbs appearance characters, preparing slices with routine methods and defining structural characters. According to the results of morphologic observation, leaves, stamen and pistil of this plant were different from the descriptions in Flora of China. The whole herb can be used in medicines, mainly including rhizomes, stems and leaves. According to the findings in the first study on microscopic structures, its rhizomes, stems and leaves were characteristic and worth identifying. The transaction tissue structures of rhizomes and stems were under developed and contained endodermis, secretory structures; Stems had sclerenchymata of different shapes of sclereids; Leaves were bifacial and had vascular bundles under midribs, which were surrounded by parenchymal sheathes. On the surface of leaves, stomata, glandular hairs and keratin lines were morphologically different in upper and lower epidermis. The herbal power had glandular hairs, sclereids and vessels. In conclusion, herbs of L. fortunei can be identified by the above histomorphological characteristics, which lays a foundation for further development and application of L. fortunei.

The clinical efficacy and safety of auricular acupuncture (AA) for treatment of primary insomnia was evaluated. After a comprehensive retrieval in domestic and foreign databases, literatures were strictly screened and Revman 5.2 software was applied to perform a Meta-analysis on eligible randomized controlled trials (RCTs). The evidence quality was assessed with GRADE profiler 3.6 software. As a result, 8 articles were included involving 894 patients. Compared among AA and sham AA, placebo AA, blank control, there was significant difference in Pittsburgh sleep quality index (PSQI) [WMD = -3.48, 95% CI (-3.96, -3.00)], sleep latency LWMD = -10.14, 95% CI (-17.16, -3.12)] and sleep awakening times [WMD = -9.98, 95% CI (-1.10,-0.48)]. Compared between AA and western medication, there was significant difference in PSQI [WMD = -3.62, 95% CI (-4.59, -2.65)]. The evidence quality was moderate in AA vs. sham AA, placebo AA or blank control, while that of the rest was extremely low. No reports of adverse events were described in all studies. In conclusion, for the treatment of primary insomnia, AA could effectively improve sleep quality, but due to the low evidence quality, cautious attitude should be taken on this conclusion, and clinical trials with large sample and high quality were needed in the further.

Objective To identify clinicopathological features of high MSI (MSI-H).Methods We enrolled 150 patients,standard microsatellite loci (BA T25,BA T26,D2S123,D5S346,D17S250) were amplified by polymerase chain reaction(PCR) with fluorescent primers,and the PCR products were analyzed by GeneMapper software;age at diagnosis,gender and site were obtained;various pathological features were observed by light microscopy;the expression of tumor infiltrating lymphocytes (CD4~+ and CD8~+) was detected by immunohistochemistry.Using a stepwise logistic regression model,a formula was generated that could be used to calculate the probability of a colorectal carcinoma being MSI-H based on pathological features.Results Among 150 cancers,MSI-H was 13.33%.Independent identifiers inclucle poor differentiation,histologic heterogeneity,Crohn's-like reaction and tumor-infiltrating lymphocytes,logistic regression formula shows a sensitivity of 70.0% and a specificity of 99.2% and a accurate ratio of 95.3% for MSI-H.Conclusion MSI-H phenotype cancer is a type of nonfamilial colorectal cancer with specific pathological features,Clinicopathological features can efficiently identify MSI-H colorectal cancers.

An analytical method of fluorescent dye-labeled oligonucleotides was established by ion pair reversed phase high performance liquid chromatography(IP-RP-HPLC) which was improved by optimizing the effects of triethylamine-acetic acid(TEAA)(0-0.15 mol/L), pH(4.5-7.0) and gradient. Comparing the retention of 5, 10 and 15-mer unlabeled oligonucleotides with that of 5'-carboxyfluorescein(5'FAM) labeled oligonucleotides, the mechanism of fluorescent dye-labeled oligonucleotides retention was studied. In addition, TaqMan~(TM) probes as wellas other common fluorescent dye-labeled oligonucleotides were concerned. The results showed that the best resolution of different length fluorescent dye-labeled oligonucleotides was observed under the condition of 0.01 mol/L TEAA and pH 7.0. The retention behavior of fluorescent dye-labeled oligonucleotides was different from that of unlabeled oligonucleotides significantly, and therefore they can be separated completely. The results indicated that the retention of unlabeled oligonucleotides enhanced with the increase of the length of molecule. In contrast, the retention of fluorescent dye-labeled oligonucleotides was reduced with the increase of the length of molecule. For the hydrophobicity of fluorescent dyes made a great impact on the retention, a longer retention time the labeled oligonucleotides would take while the hydrophobicity of fluorescent dyes was higher. However, the effect of the hydrophobicity was limited as the length was increased to a certain level.

To observe therapeutic effects of acupuncture on female's climacteric depression and to study on the mechanism. Methods Sixty cases enrolled were randomly divided into an acupuncture group and a control group, 30 cases in each group. In the acupuncture group, acupuncture were given at Ganshu (BL 18), Shenshu (BL 23), Xinshu (BL 15), etc. with uniform reinforcing-reducing method, once each day, and the control group were treated with oral administration of fluexertine hydrochloride, 20 mg, once daily. HAMD scale was used for assessment before treatment and 2,4,6 weeks after treatment. Blood dopamine (DA), norepinephrine (NE) and 5-hydroxy-indoleacetic acid (5-HIAA) contents were detected before treatment and after one therapeutic course. Results The total effective rate was 86.7% in the acupuncture group and 92.9% in the control group with no significant difference between the two groups (P > 0.05). After treatment, DA content increased significantly in the acupuncture group with a significant difference as compared with that of the control group (P < 0.05); and after treatment NE and 5-HIAA contents in the two groups significantly increased as compared with that before treatment (P < 0.05, P < 0.01), with no significant difference between the two groups (P > 0.05). Conclusion Acupuncture can benignly and comprehensively regulate general functions, and increase contents of monoamines in the body, so as to play the role of anti-depression.

The effects of dietary supplementation with Clostridium butyricum on growth performance and humoral immune response in Miichthys miiuy were evaluated. One hundred and fifty Miichthys miiuy weighing approximately 200-260 g were divided into five groups and reared in 15 tanks with closed circuiting culture system. The animals were fed 5 diets: basal diet only (control) or supplemented of the basal diet with C. butyricum at doses of 10(3) (CB1), 10(5) (CB2), 10(7) (CB3) or 10(9) (CB4) CFU/g. Compared with the control, the serum phenoloxidase activity was significantly increased by the supplementation (P<0.05), acid phosphatases activity was increased significantly (P<0.05) at the doses of 10(9) CFU/g. Serum lysozyme activity peaked at dose of 10(7) CFU/g and in the skin mucus at dose of 10(9) CFU/g. Immunoglobulin M level in the serum and skin mucus was increased except at dose of 10(3) CFU/g (P<0.05). The growth at the dose of 10(9) CFU/g was higher than that of the control (P<0.05). It is concluded that supplementation of C. butyricum can mediate the humoral immune responses and improve the growth performance in Miichthys miiuy.
