Apolipoprotein C3 (APOC3) is a multifunctional protein.Its concentration is positively correlated with triglyceride (TG) levels and is an independent risk factor for coronary heart disease (CAD) prediction and development.Recent studies showed that APOC3 could not only regulate triglyceride-rich lipoproteins (TRL) metabolism,but also regulated endothelial function,that is,it could induce endothelial dysfunction and disorders of lipid metabolism.Gradually,APOC3 induces atherosclerosis (AS),increases the risk of the occurrence of CAD and other related diseases.APOC3 polymorphisms are also closely related to related diseases.

Objective: To investigate the prevalence and influencing factors of adolescent depression symptoms in Zhejiang, so as to provide reference for improving their mental health. Methods: The middle school and university students in 11 cities of Zhejiang Province were selected by stratified cluster random sampling method. The depression symptoms of the adolescents were assessed by Center for Epidemiological Survey-Depression Scale ( CES-D ) and the influencing factors were analyzed by multivariate logistic regression model. Results: A total of 25 855 students were investigated, and 25 614 ( 99.07% ) valid questionnaires were collected. The detection rate of depressive symptoms was 26.86%(6 879 cases). The detection rate of depressive symptoms in girls was 29.75%, which was higher than 24.12% in boys ( P<0.05). The detection rate of depressive symptoms in high school students was 31.74%, the highest compared with other grades. The multivariate regression analysis showed that female students ( OR=1.690, 95%CI: 1.592-1.794 ), resident students ( OR=1.071, 95%CI: 1.010-1.137 ) , internet addiction ( OR=2.948, 95%CI: 2.527-3.439 ) , attempt smoking ( OR=1.516, 95%CI: 1.359-1.690 ), drinking ( OR=1.624, 95%CI: 1.525-1.729 ), bullied in the past 30 days ( OR=3.143, 95%CI: 2.938-3.363 and having serious injuries within a year ( OR=1.369, 95%CI: 1.263-1.543 ) were associated with adolescents who had depressive symptoms. Conclusions The detection rate of depressive symptoms is relative 26.86% among adolescents of Zhejiang Province. The students who are female, live on campus, have internet addiction, have been bullied or seriously injured, smoke and drink are more likely to have depressive symptoms.

Objective:To observe the effect of acupoint massage plus acupoint sticking therapy for the stress reaction during postoperative anesthesia recovery period in patients undergoing nasal endoscopic surgery.Methods:A total of 120 patients undergoing nasal endoscopic surgery were included,and all patients were under trachea intubation and general anesthesia.The patients were randomized into an observation group and a control group,with 60 patients in each group.Patients in the control group received conventional anesthesia resuscitation,while patients in the observation group received acupoint massage plus acupoint sticking therapy on the basis of conventional anesthesia resuscitation.Changes in the heart rate (HR),systolic blood pressure (SBP) and diastolic blood pressure (DBP) were observed at three time points including the end of the surgery (TO),the removal of the tracheal tube (T1) and 10 min after the removal of the tracheal tube (T2).The awakening and tube removal time,choking cough and restlessness,and adverse reactions (dizziness,nausea and vomiting) in 24 h post-surgery period were compared.Results:At T1 and T2,the comparisons of HR,SBP and DBP between the two groups showed statistical significance (all P＜0.05).Intra-group comparisons showed that the HR,SBP and DBP of the control group at T1 and T2 were significant different from those at TO (all P＜0.05).There were significant differences in the awakening time and tube removal time between the two groups (both P＜0.05).The incidences of choking cough and restlessness were 8.3％ and 3.3％ respectively in the observation group,versus 53.3％ and 30.0％ in the control group,and the between-group comparisons showed statistical significance (both P＜0.05).The incidences of dizziness,nausea and vomiting in 24 h post-surgery period were 3.3％,5.0％ and 0.0％ respectively in the observation group,versus 43.3％,33.3％ and 25.0％ in the control group,and the between-group comparisons showed statistical significance (all P＜0.05).Conclusion:Acupoint massage plus acupoint sticking therapy can effectively regulate the stress reaction during postoperative anesthesia recovery period in patients undergoing nasal endoscopic surgery,and maintain a stable internal environment.

Objective To investigate the possibility and feasibility of the whole genome microarray scanning technique in clinical cytogenetic diagnosis of an uncertain karyotype and mentally retarded child. Methods The karyotype analysis of the mental development delayed child was 47, XY+mar. Genomic DNA was extracted from the peripheral blood and the whole genome microarray scanning technique was used to analyze the derivative chromosome. Results The whole genome microar-ray scanning technique indicated the derivative chromosome fragment had originated from 9p13.1-p24.3. Conclusions Com-paring to conventional cytogenetic analysis methods, the whole genome microarray scanning technique is of high resolution, high-throughput and high accuracy, which can detect the submicroscopic chromosomal aberrations and replace the conven-tional karyotype analysis.

Objective To explore the correlation between phenotype and genotype of 5α-reductase 2 deficiency. Methods The clinical data of five children with 5α-reductase 2 deficiency were retrospectively analyzed and the relation between their clinical phenotype and genotype were analyzed. Results All of these five children presented small penis and testicular hypoplasia, three of whom had ones similar to the clitoris appearance. The testosterone/dihydrotestosterone (T/DHT) ratio was 10.26-64.99 after human chorionic gonadotropin (hCG) stimulation. Gene detection showed one case had c.680G>A homozygous mutation and the others were compound heterozygous mutations. The mutations were mainly missense mutations, followed by deletion, duplication and nonsense mutations. Conclusion The 5α-reductase 2 deficiency has different degrees of abnormal genital development. Genetic testing contributed to the diagnosis of this disease.

To evaluate in vitro release and transdermal behaviors of Huoxue Zhitong gel, modified Franz diffusion cell methods was applied to investigate in vitro transdermal absorption of Huoxue Zhitong gel and the content of paeonolan in receptor fluid composed of PEG400%-95% ethanol-water (l:3:6)were determined by HPLC.

[Summary] Microcephalic or Majewski's osteodysplastic primordial dwarfism type Ⅱ ( MOPD Ⅱ) is an extremely rare genetic disease mainly caused by pericentrin ( PCNT) gene mutations. This paper reported one 13-year-old boy, who was admitted because of the slow growth for more than 13 years and deepened skin color over six months. He was diagnosed as MOPD Ⅱ associated with a combination of growth hormone deficiency, type 2 diabetes, hypertension, acanthosis nigricans, multiple café-au-lait spots. On magnetic resonance imaging of brain, no vascular malformations such as aneurysms were shown. There were novel compound heterozygous mutations of PCNT gene in the patient, with the nonsense mutations of c. 502C > T ( p. Gln168 * heterozygous variation) and c. 3103C > T (p. Arg1035* heterozygous variation). His father carried a nonsense mutation c. 3103C > T ( p. Arg1035 *heterozygous variation ) and his mother had a nonsense mutation c. 502C > T ( p. Gln168 * heterozygous variation). After treatment with metformin for three months, his blood glucose returned to normal, and acanthosis nigricans was improved. It seems critical to evaluate the abnormal condition of blood vessels regularly for MOPD Ⅱpatients with PCNT gene mutations.

Objective To explore the clinical features and molecular diagnosis of 46, XY disorder of sex development (46, XY DSD).Methods The clinic data of one child with 46, XY DSD raised as female were retrospectively analyzed, and related literatures were reviewed.Results The 11.5-year-old child raised as female visited clinic due to, “accidently found clitoral hypertrophy for half month”. Preliminary series of laboratory examinations supported the diagnosis of 46, XY DSD, high gonadal hormone dysplasia. DNA sequencing of the whole genome exon group showed a heterozygous mutation of c.937C>T, p.Arg313Cys inNR5A1 gene. No abnormality was detected in her father, while her mother was a heterozygous mutation carrier. Conclusions 46, XY DSD can be diagnosed by the whole genome exon gene sequencing.
