ObjectiveTo investigate the association between nucleotide polymorphisms ofGRIN3A gene and clinical characteristic of Kawasaki disease (KD) in children in Han population in central Chinese.MethodsA case-control study was performed. A total of 191 children with KD were recruited and 217 healthy children were served as controls. The distribution of SNP was determined by PCR-RFLP. Arterial lesions were detected by echocardiographic.ResultsThe distribution of three genotypes (CC, CG, GG) in SNP (rs7849782) was statistically difference between KD and control groups (P=0.034), and C allele was associated with KD susceptibility (OR=1.46, 95%CI: 1.10-1.92,P=0.007). In children with KD, the polymorphism of SNP loci was signiifcantly associated with oral mucosa lesions and coronary artery lesion (P<0.05), but not associated with conjuncti-val hyperemia, hand-foot edema, rash, and lymphadenopathy (P>0.05). The polymorphism of SNP loci was also associated with the levels of erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) (P<0.05).ConclusionThe ploymorphism of SNP loci ofGRIN3A gene (rs7849782) was associated with the susceptibility of KD. The C allele was the risk factors. The poly-morphism of SNP was associated with oral mucosa lesions and coronary artery lesion, and may affect the levels of ESR and CRP.

Journal of Shanghai Jiaotong University(Medical Science) 2020;40(1):51-57
Objective:To observe the effect of sleep apnea hypopnea syndrome (SAS) on sleep staging of bipolar disorder patients in different states. Methods:A total of 210 healthy controls aged 18-65 and 235 bipolar disorder patients of the same age were collected. The bipolar disorder patients were divided into depressive, manic and mixed states. Sleep time structure, sleep posture, heart rate and other indicators were collected by using sleep quality assessment system based on cardiopulmonary coupling analysis. According to whether the apnea-hypopnea index (AHI) was ≥ 5 times/h, whether they had SAS were determined. Two-way multivariate analysis of variance was conducted, investigating the effect of clinical states and SAS, on several sleep indicators. Results:SAS significantly prolonged rapid eyes movement (REM) sleep time of patients in depressive state (P=0.000) and shortened deep sleep time of patients in manic state (P=0.011). In addition, the heart rate during sleep (including deep sleep, light sleep and REM sleep) of patients in manic state increased most significantly among the three clinical states (P=0.000). Lying supine aggravated SAS most significantly in manic state among the three clinical states (P=0.002). Conclusion:SAS has different effects on the sleep staging of bipolar disorder patients in different states.

p-Hydroxybenzoic acid can be oxidized by hydroxyl radicals ( · OH) to produce electroactive 3,4-dihydroxybenzoic acid (3,4-DHBA). Therefore, it can be used as a probe to detect ·OH. In this work, 3,4-DHBA/ PPy / TiO2 molecularly imprinted polymer film was prepared for indirect determination of ·OH based on its recognition ability for 3,4-DHBA. The sensor was constructed by using pyrrole as the functional monomer and 3, 4-DHBA as the template molecule. The sensor was characterized by scanning electron microscope and different electrochemical methods. The preparation and determination conditions, such as the electropolymerization cycle number, pH value in the electropolymerization process, and elution time, were optimized. Under the optimal conditions, a linear range of 1. 0×10-8-1. 0×10-6 mol/ L was obtained for 3,4-DHBA and the detection limit was down to 4. 2×10-9 mol/ L (S / N = 3). This new approach was of low cost and convenience, and was successfully applied to measure the concentration of ·OH in the atmosphere.

Multiple epitopes from one or more viruses can be lined up and co-expressed in one vector to generate multi-epitopes DNA vaccines. In the study, four recombinant plasmids were constructed based on HA and NP gene of avian influenza virus (AIV) (H5N1): (1) pIRES/HA, carrying the complete HA gene; (2) pIRES/tHA, carrying a truncated HA gene fragment of major neutralizing antigenic epitopes; (3) pIRES/tHA-NPep, in which three CTL epitopes of NP gene of AIV were fused to the truncated HA from the C-terminal; and (4) pIRES/tHA-NPep-IFN-gamma, which was constructed by replacing neo gene in pIRES/ tHA-NPep with IFN-y of chicken. Fifty five SPF chickens were randomly divided into five groups and immunized with the above four constructs and control plasmid. Each chicken was intramuscally immunized with 200 microg plasmid DNA three times in a two-week interval. Two weeks after the third immunization, chickens were injected with H5N1 subtype avian influenza virus. Before the virus loading no detectable antibodies to HA were found in the chicken serum; but high levels of HI antibodies were detected in the serum of the survived chickens. The percentages of CD4+ and CD8+ T lymphocyte in peripheral blood of immunized chickens increased steadily after the vaccination. After virus loading all chickens in the control group died within three to eight days, and the survival rates of the four DNA vaccine groups were as follows: pIRES/HA, 54.5%; pIRES/tHA, 30%, pIRES/ tHA-NPep, 36.3%, pIRES/tHA-NPep-IFN-gamma, 50%. These results indicated that multi-epitopes DNA immunization can induce immune response and protect chickens from homologous virus loading.

In 2013, the World Health Organization reported the first case of human infection with a new influenza A (H7N9) virus in China. This has caused damage and panic within certain areas in China. Therefore, analysis of this virus with bioinformatics technology is very necessary. Neuraminidase (NA) is one of the most important antigens of the influenza virus and an important target for anti-flu drugs. In this study, the nucleotide and protein sequences of NA gene of A/H7N9 influenza viruses were retrieved from the NCBI database, and MEGA 5.0 software was employed to construct a phylogenetic tree based on the nucleotide coding sequence; BioEdit software was used to align the nucleotide and protein sequences of NA and calculate the homologies of nucleotides and amino acids and then to analyze the important mutation sites of NA gene. The results demonstrated that the spread of influenza virus H7N9 showed certain geographical and temporal relations. The H7N9 virus isolated from China in 2013 belonged to Euroasiatic serotype, and its NA stalk region hadobvious variation, which may be one of the reasons that this virus infects human. These analyses may be very helpful for understanding the evolutionary relationship and mutation trend of A/H7N9 influenza viruses.

OBJECTIVETo explore the relationship between test anxiety and personality, self-esteem in grade one senior high school students.
METHODSTotally 538 senior high school students of grade one were investigated by Test Anxiety Scale (TAS), Eysenck Personality Questionnaire (EPQ) and Self-Esteem Scale (SES) in a Senior High School in Shandong Province.
RESULTSThe prevalence of test anxiety among all the surveyed students was rated 65.2%. The Psychoticism (P) (51.60 +/- 9.66) or Neuroticism (N) (51.57 +/- 10.75) factor score of EPQ in students with test anxiety was significantly higher than that in students without test anxiety (48.07 +/- 8.62, 45.65 +/- 10.14) (P < 0.001), while the Extroversion or Introversion (E) score (50.76 +/- 11.09) was on the contrary (53.68 +/- 11.60) (P < 0.01). The total score of TAS was significantly positively related to the P (r = 0.14) and N (r = 0.36) factor score and significantly negatively related to the E factor score of EPQ (r = -0.15) (P < 0.001). The prevalence of test anxiety in introversive students (72.3%) was higher than that in extroversive students (53.2%) (P < 0.05), and that in students with unstable emotion (81.4%) and in students with apparent psychoticism (84.1%) were also higher than that in those with stable emotion (41.0%) and in those without psychoticism (57.7%) (P < 0.01). The total score of SES in students with test anxiety (29.12 +/- 4.41) was significantly lower than that in students without test anxiety (30.29 +/- 4.25) (P < 0.01). The total score of TAS was significantly negatively related to the total score of SES (r = -0.23) (P < 0.001).
CONCLUSIONTest anxiety should be related to the personality and self-esteem, and the prevalence of test anxiety in introversive, unstable emotional, apparent psychoticism or low self-esteem students should be higher.

To investigate the role and mechanism of ceramide (Cer) regulation in alcohol-induced neuronal proliferation and the newborn neurons formation, we used sphingomyelin synthase 2 (predominant enzyme of Cer metabolism) knockout (SMS2(-/-)) and wild type (WT) female mice to establish the model of prenatal alcohol exposure. In 24 h after being given birth (postnatal day 0, P0), the offspring of model mice received blood sphingomyelin (SM) measurement with enzymatic method. On P0, P7, P14 and P30, the proliferation of granule cells in the dentate gyrus and newborn neurons were investigated with immunofluorescent labeling. The expression of protein kinase Cα (PKCα) in the hippocampus was tested with Western blot analysis. The results showed that the SM level of blood in SMS2(-/-) pups was significantly lower than that in WT pups. No matter in SMS2(-/-) or WT mice, the prenatal alcohol exposure down-regulated the SM levels in pups with dose-dependency. In both SMS2(-/-) and WT pups, the number of proliferative neurons and newborn neurons in the dentate gyrus gradually decreased with the growing age. Compared with the WT pups, SMS2(-/-) pups showed significantly more proliferative neurons and newborn neurons in the dentate gyrus. Notably, prenatal alcohol exposure dose-dependently increased proliferative neurons and newborn neurons in the dentate gyrus in both WT and SMS2(-/-) pups. The hippocampal expression of PKCα protein in SMS2(-/-) mice was lower than that in WT mice, and prenatal alcohol exposure could up-regulate the PKCα protein expression in both WT and SMS2(-/-) mice with dose dependency. These results suggest that alcohol exposure during pregnancy can induce the compensatory neural cell proliferation and the production of newborn neurons in offspring, and the Cer-ceramide-1-phosphate (C1P) pathway is involved in alcohol-induced neural cell proliferation. The activation of PKCα may be a key step to start the Cer-C1P pathway and up-regulate the alcohol-induced neural cell proliferation and the newborn neurons formation.

Based on the genomic sequence of SARS-CoV strain BJ101, antigenic immunodominant genes coding for the structure proteins of SARS-CoV were predicted by bio-informatics methods, and two chimeric genes A and B with multi-immunodominants lined up by Gly-Pro-Gly linker were synthesized. The chimeric genes were cloned into plasmid pGEX-6p-1 and expressed in E. coli with IPGT inducing. BALB/c mice were immunized with the purified recombinant fusion protein. The specificity of monoclonal antibodies were tested with a commercial ELISA kit for detecting antibody against SARS-CoV. The results showed that two peptides with molecular weights of 34kD and 35kD expressed by the two chimeric genes could be recognized by SARS patient convalescent serum in Western blot. Six positive hybridoma cell lines stably secreting monoclonal antibodies were selected. The subtype of monoclonal antibody D3C5 is IgG2a, and subtypes of all other five monoclonal antibodies are IgG1. Light chains of all monoclonal antibodies are kappa. With a commercial SARS-CoV antibodies detection ELISA kit, five out of six monoclonal antibodies were positively recognized. In western blot analysis with inactived virus cultures, D3D1 specifically recognized a band of about 180 kD. To further analyse the epitopes corresponding to the monoclonal antibodies, six oligoes (S1-S6) from S gene were synthesized and expressed. The results showed that the monoclonal antibodies D3D1 and D3C5 specifically recognized expression product of S2 and S5 oligoes, respectively. The S2 and S5 oligoes are corresponding to 447-458aa and 789-799aa of SARS-CoV S protein respectively.

To study relevant risk factors of Shenmai injection induced adverse reactions by using Logistic model and ROC curve, and made the prediction for the occurrence of relevant adverse reactions/events. Case data of patients treated with Shenmai injection were collected by using the prospective, multi-center, large-sample, nested-case control method, in order to analyze the risk factors of Shenmai injection-induced adverse reactions/events, establish the logistic model and draw the receiver operating characteristic (ROC) curve for risk factors. During the study, 7632 patients (including 3 477 males and 4 155 females) were included, and eight of them suffered adverse reactions/events. Based on a multi-factor Logistic model analysis, the age (> or = 50 years) (OR = 5.061, 95% CI: 2.197-7.924; P = 0.001), the total number of medication days (OR = -1.020, 95% CI: -l.652 - 0.388; P = 0.002) and the single dose (OR = 0.245, 95% CI: 0.127-0.364; P = 0.000) were significant independent risk factors for Shenmai injection-induced adverse reactions/events. According to the results, ROC curves were drawn with age (> or = 50 years), the total number of days of inedication and single dose; The area under ROC curves the joint predictor (0.9753, 95% CI: 0.9443-1.000, P < 0.005) was larger than that of the other three single indexes, with a higher risk prediction value. The independent risk factors for Shenmai injection-induced adverse reactions/events included the age (> or = 50 years), the total number of days of medication and single dose. In clinical practice, the age (> or = 50 years), the total number of days of medication and the medication dose can be substituted in the joint predictor calculation formula (P = 1 / [1 + e(-(-21.58 + 5.061 x Xage - 1.020 x Xd + 0.245 x X(mL)] to predict the potential adverse reactions of patients and adjust the dosage regimen.
