ABSTRACT
Objective To explore the intervention effect of the combination of medicine and education on teachers and parents of children with attention deficit hyperactivity disorder (ADHD).Methods The students in Grade 1 to 3 of 6 public primary school (6～11 years old) were enrolled by stratified sampling method and randomly divided into the experimental group and the control group.All the students were screened for ADHD,and the children diagnosed with ADHD and their parents and teachers were enrolled into study as the research object.The children in the control group were given oral short-effect methylphenidate hydrochloride tablets and their parents underwent routine health education,while the parents and teachers in the experimental group were given both the routine health education and systematic training.Before and after training,the awareness rates of ADHD knowledge among parents and teachers were observed,and the clinical effects of two groups were compared.Results The control group included 71 children with ADHD,71 pairs of parents and 31 teachers,while the experimental group included 68 children with ADHD,68 pairs of parents and 34 teachers.The difference of general data between the two groups has no statistical significance (P＞0.05).Before intervention,there was no significant difference in awareness rate of ADHD knowledge among teachers and parents in the two groups (P＞0.05).After the intervention,the awareness rate of ADHD knowledge in teachers of the control group did not change obviously,while which in parents of the control group and the parents and teachers in the experimental group were significantly improved,and the improvement effect in the experimental group was significantly better than that of the control group (P＜0.05).The scores of the SNAP-Ⅳ scale in both groups were significantly decreased,and the scores of the experimental group were significantly lower than those in the control group.The significant rate and total effective rates of the experimental group were significantly higher than those in the control group (P＜0.05).Conclusion The intervention effect of combination of medicine and education on teachers and parents of children with ADHD is definite,which is worthy of further research.
ABSTRACT
The isolated type of orofacial cleft, termed non-syndromic cleft lip with or without cleft palate (NSCL/P), is the second most common birth defect in China, with Asians having the highest incidence in the world. NSCL/P involves multiple genes and complex interactions between genetic and environmental factors, imposing difficulty for the genetic assessment of the unborn fetus carrying multiple NSCL/P-susceptible variants. Although genome-wide association studies (GWAS) have uncovered dozens of single nucleotide polymorphism (SNP) loci in different ethnic populations, the genetic diagnostic effectiveness of these SNPs requires further experimental validation in Chinese populations before a diagnostic panel or a predictive model covering multiple SNPs can be built. In this study, we collected blood samples from control and NSCL/P infants in Han and Uyghur Chinese populations to validate the diagnostic effectiveness of 43 candidate SNPs previously detected using GWAS. We then built predictive models with the validated SNPs using different machine learning algorithms and evaluated their prediction performance. Our results showed that logistic regression had the best performance for risk assessment according to the area under curve. Notably, defective variants in MTHFR and RBP4, two genes involved in folic acid and vitamin A biosynthesis, were found to have high contributions to NSCL/P incidence based on feature importance evaluation with logistic regression. This is consistent with the notion that folic acid and vitamin A are both essential nutritional supplements for pregnant women to reduce the risk of conceiving an NSCL/P baby. Moreover, we observed a lower predictive power in Uyghur than in Han cases, likely due to differences in genetic background between these two ethnic populations. Thus, our study highlights the urgency to generate the HapMap for Uyghur population and perform resequencing-based screening of Uyghur-specific NSCL/P markers.

Objective Sodium-bile acid cotransporter plays an important role in the development of Echinococcus.The present study aimed to clone sodium bile acid cotransporter gene in Echinococcus multilocularis (EmSBACT5) and to analyze the bioinformatics of its coding protein.Methods EmSBACT5 gene was amplified by reverse transcription RCR (RT-PCR) technology and its nucleotide sequence was sequenced.Bioinformatics softwares were used to predict and analyze the physical and chemical properties, hydrophilicity/hydrophobicity, transmembrane domain, post-translational modification sites, structural domain, secondary structure, tertiary structure, subcellular localization and biological functions of the coding protein.Results The complete open reading frame was amplified with 654 bp in length, encoding 217 amino acids.The homology of the nucleic acid sequence and amino acid sequence of EmSBACT5 gene were 98% and 96% with the published SBACT5 in Echinococcus granulosus (EgSBACT5) respectively.Protein analysis results showed that the molecular formula of EmSBACT5 protein was C1141H1797N273O284S11.Its relative molecular mass was 24240 and isoelectric point was 8.99.There were 9 post-translational modification sites and 4 typical domains.Alpha helical, β-sheet, β-turn and random coil accounted for 29.95%, 31.80%, 7.83% and 30.41%, respectively.This protein was a hydrophobic membrane protein and was mainly located in the cytoplasmic membrane, and it might play a role in the processes of material transport and signal transmission.Conclusion The EmSBACT5 gene was cloned successfully and the informatics characteristics of its coding protein were obtained, which provides basic information for prevention and control of echinococcosis.
ABSTRACT
At present,corresponding cell-free parasite DNA molecules (CFPD) has been detected in serum,plasma,urine,saliva and other bodily fluids of a variety of the patients with parasitic diseases.Due to its high specificity and sensitivity,the CFPD shows a strong advantage of noninvasive diagnosis and continuous monitoring,etc.in parasitic diseases.This article namely reviews the current research of CFPD in the patients with parasitic disease at home and abroad in recent years,so as to provide new ideas for the development direction of parasitic disease diagnosis in the future.The current related problems are discussed in the mean time.
ABSTRACT
Polyhydroxyalkanoates (PHA) are diverse polyesters synthesized by a variety of bacteria as intracellular carbon and energy storage compounds. As bio-renewable and biodegradable materials with diverse properties, PHA have drawn industrial attentions for their potential applications in many fields. This review focuses on recent strain developments for PHA production via cofactor engineering and metabolic engineering. The microaerobic production of PHA and application of PHA synthesis genes for improving robustness of industrial microorganisms are addressed.
