Objective To estimate the incentive and guidance of degree policy for the doctoral student's capacity-building. Methods Totally 1185 published SCI papers completed by 1 013 doc-toral students from 2008 to 2012 in Capital Medical University were filed and impact factors of these SCI journals taken as analysis objects were organized using Microsoft Office Excellsoftware. ANOVA was used for data procession and t-test was used for statistical analysis. P<0.05 signifies statistically significant difference. Results This study showed that 97%doctoral students can complete SCI paper publication in compliance with requirements of doctoral degree policy. Quality of SCI papers of aca-demic degree PhDs was higher than that of professional degree PhDs(P=0.00). Level of SCI papers of PhDs in basic disciplines was higher than that of PhDs in clinical disciplines (P=0.00). In addition, this study found that higher leveled SCI papers originated primarily from the national key disciplines and co-first authors. Conclusions The appropriate degree policies play an important guiding role in enhancing the quality of doctoral students' education. Degree-granting units should make more specific guidance policies according to different types of disciplines and cultures, such as raising published arti-cle requirements to the clinical professional PhDs, improving and standardizing relevant degree poli-cies about SCI papers published by co-first authors, strengthening disciplinary conditions building, etc.

OBJECTIVETo investigate the association of DNA methyltransferase 3B (DNMT3B) gene polymorphism with the development of early-onset schizophrenia.

METHODSA single nucleotide polymorphism (rs6119954) of DNMT3B gene was genotyped in 279 early-onset schizophrenic patients and 395 healthy controls, using TaqMan SNP Genotyping Assays. To detect the interaction between the DNMT3B gene and environmental factors, the prenatal information of the patients was collected.

RESULTSGenotype distribution of the rs6119954 locus was significantly different between patients and controls (Chi-square = 12.27, P< 0.01). The frequency of the G allele of this locus was significantly higher in patients than in controls (Chi-square = 12.76, P< 0.01). The G allele was highly associated with an earlier age of onset (P= 0.026). No interaction between the DNMT3B gene and environmental factors was found.

CONCLUSIONDNMT3B gene is associated with early-onset schizophrenia and rs6119954 may plays an important role in age of onset of schizophrenia.

Wearable devices are used in the new design of the maternal health care system to detect electrocardiogram and oxygen saturation signal while smart terminals are used to achieve assessments and input maternal clinical information. All the results combined with biochemical analysis from hospital are uploaded to cloud server by mobile Internet. Machine learning algorithms are used for data mining of all information of subjects. This system can achieve the assessment and care of maternal physical health as well as mental health. Moreover, the system can send the results and health guidance to smart terminals.

ObjectiveTo explore the clinical effect of Tiaoxin formula in the treatment of patients with coronary heart disease and anxiety/depression and its impact on serum levels of 5-hydroxytryptamine （5-HT）， β- thromboglobulin （β-TG） and myeloperoxidase （MPO）. MethodA total of 66 patients with coronary heart disease and anxiety/depression were randomly divided into the Tiaoxin formula group and Deanxit group， 33 cases in each group. Both groups were given fundamental western treatment for coronary heart disease. Additionally， the Deanxit group was treated with flupentixol and melitracen tablets and the Tiaoxin formula group was treated with Tiaoxin Formula. The treatment lasted 8 weeks. Before and after treatment， the changes of clinical efficacy， Patient Health Questionnaire （PHQ-9）， Generalized Anxiety Disorder （GAD-7） scale， Seattle Angina Questionnaire （SAQ）， heart rate variability， and serum 5-HT， β-TG and MPO levels， and incidence of adverse reactions in the two groups were observed. ResultThere was no significant difference in the baseline indexes of patients in the two groups， and thus the two groups were comparable. After treatment for 8 weeks， the total effective rate for traditional Chinese medicine （TCM） syndromes in the Tiaoxin Formula group was 87.88% （29/33） higher than 63.64% （21/33） in the Deanxit group （Z=-2.653， P<0.05）. Compared with those before treatment， the PHQ-9 and GAD-7 scores of the two groups were decreased at week 4 and 8 of treatment （P<0.05）， and there was no statistical difference between two groups. And the SAQ dimension scores of the two groups were increased at week 4 and 8 of treatment （P<0.05）. Compared with the Deanxit group， the Tiaoxin Formula group had elevation in two dimension scores： Physical limitation and angina stability （P<0.05）. Compared with the conditions before treatment， the serum 5-HT level in the two groups were increased， while the β-TG and MPO levels were lowered （P<0.05）， and there was no distinct difference between two groups. In addition， the standard deviation of normal-to-normal intervals （SDNN） and standard deviation of average normal-to-normal intervals （SDANN） of the heart rate variability in the Tiaoxin formula group were elevated after treatment （P<0.05）， which were more significant than those of the Deanxit group （P<0.05）. During the treatment period， the incidence of adverse drug reactions in the Tiaoxin formula group was lower than that in the Deanxit group （P<0.05）， and no adverse events were observed in the two groups. ConclusionTiaoxin formula was effective for the treatment of patients with coronary heart disease accompanied by anxiety and depression， which improved the clinical symptoms， increased serum 5-HT levels， and decreased serum β-TG and MPO levels， and had few adverse reactions and high safety for patients， showing a high clinical value.
