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.

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 evaluate the effectiveness of interventions for human papillomavirus ( HPV ) vaccine hesitancy among female university students based on the precaution adoption process model (PAPM), so as to provide the evidence for improving the coverage of HPV vaccine in this population. Methods : HPV vaccine hesitant female students were selected using a cluster sampling method from Zhejiang Chinese Medical University, and randomly assigned to the PAPM group and control group. Students in the PAPM group received PAPM-based interventions for HPV vaccine hesitancy, while students in the control group were given routine interventions. The HPV-related knowledge, HPV vaccine-related knowledge and HPV vaccine hesitancy scores were collected from both groups prior to interventions ( T0 ), 0 ( T1 ), 1 ( T2 ) and 3 months post-interventions ( T3 ), and the effectiveness of interventions was evaluated using analysis of variance for repeated measures. Results : There were 147 students in the PAPM group and 141 students in the control group. In the PAPM group, 36.73% of the students majored in medical sciences, and 48.23% were freshmen; in the control group, 39.72% majored in medical sciences, and 50.35% were freshmen. The mean scores of HPV- and HPV vaccine-related knowledge were significantly greater in the PAPM group than in the control group, respectively ( T1, 5.29 vs. 4.91; T2, 4.27 vs. 4.22; T3, 4.22 vs. 4.04; P<0.05 ); however, no significant differences were detected in the HPV vaccine hesitancy scores between the two groups, respectively ( T1, 2.98 vs. 2.95; T2, 3.07 vs. 3.07; T3, 3.08 vs. 2.97; P>0.05 ). The mean scores of the confidence dimension ( T1, 3.37 vs. 3.23; T2, 3.48 vs. 3.40; T3, 3.38 vs. 3.25 ) and the dimension of influence by others ( T1, 3.44 vs. 3.33; T2, 3.42 vs. 3.37; T3, 3.46 vs. 3.27 ) were significantly greater in the PAPM group than in the control group (P<0.05), while the mean scores of the complacency dimension were significantly lower in the PAPM group than in the control group ( T1, 1.98 vs. 2.03; T2, 2.06 vs. 2.20; T3, 2.18 vs. 2.15; P<0.05 ). Conclusions PAPM-based interventions for HPV vaccine hesitancy may effectively improve the awareness of HPV and HPV vaccines, reduce complacency, and enhance the influence by others among female university students.

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.
