OBJECTIVETo research the regulating effects of different dosages of ginseng with hairy antler on the sexual dysfunction model of the gonad and the structure of shenyangxu male rats induced with adenine, and to look for the best compatible proportion of ginseng to hairy antler in the model.

METHODSHealthy male SD rats, 2 months of age and (220 +/- 20) g in weight, were randomly assigned to 13 groups: normal group, model group, ginseng group, hairy antler group and 9 different proportion groups of ginseng to hairy antler. Observations were made on the exterior syndrome, testosterone in sera, weight index of the prostate and seminal vesicle, and tissue changes of the testis in the experimental rat model.

RESULTSDosages of different proportions of ginseng to hairy antler had different improving effects on the exterior syndrome, testosterone in sera, weight index of the prostate and seminal vesicle, and tissue changes of the testis.

CONCLUSIONDifferent proportions of ginseng to hairy antler had different improving effects on the sexual dysfunction model of male rats induced with adenine, and the best compatible proportion of ginseng to hairy antler was 5 to 2, that is, 0.45 g ginseng to 0.18 g hairy antler or 0.90 g ginseng to 0.36 g hairy antler.

Objective:To investigate the prevalence of depressive disorders among school students aged 6-16 years in Beijing, the effect of age and gender on the prevalence, and the behavioral and emotional profiles of identified students with depressive disorders.Methods:The prevalence of depressive disorders in primary and secondary school students aged 6-16 years in Beijing from January 2012 to December 2014 was examined by a multistage stratified random sampling method.In the first stage, the Achenbach′s Child Behavior Checklist (CBCL) was used to identify high-risk children and adolescents.In the second stage, the high-risk group was further screened by Mini International Neuropsychiatric Interview for Children and Adolescents (MINI-KID), and then two psychiatrists made the final diagnosis according to the diagnostic criteria of the fourth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-Ⅳ). This study was a prospective epidemiological investigation.The effect of age and gender on the disease prevalence was analyzed by Chi- square test. Results:About 2.29% (234/10 215 cases) of the school students aged 6-16 years in Beijing had depressive disorders.The incidence of depressive disorders was 1.80% (106/5 866 cases) in boys and 2.94% (128/4 349 cases) in girls.There is an age effect on the prevalence of depression.As the age increases, the morbidity of depressive disorders increases.The age of 12 years was a critical turning point, and the peak incidence was reached at around the age of 15 years.The emotional and behavioral problems of patients with depressive disorders mainly include social problems, withdrawal depressed, anxiety and depressed, somatic complaints, and aggressive behavior.Conclusions:The prevalence of depressive disorders among school students aged 6-16 years in Beijing is 2.29%.Depressive disorders occur in primary and middle school students of all ages.More attention should be paid to the mood of students before and after the entrance exams for junior high school and senior middle school, especially the girls′ mood.In the process of screening, diagnosis and treatment of depressive disorders, the atypical symptoms of depression need to be paid more attention.

Esophageal squamous-cell carcinoma (ESCC) is one of the most lethal malignancies in the world and occurs at particularly higher frequency in China. While several genome-wide association studies (GWAS) of germline variants and whole-genome or whole-exome sequencing studies of somatic mutations in ESCC have been published, there is no comprehensive database publically available for this cancer. Here, we developed the Chinese Cancer Genomic Database-Esophageal Squamous Cell Carcinoma (CCGD-ESCC) database, which contains the associations of 69,593 single nucleotide polymorphisms (SNPs) with ESCC risk in 2022 cases and 2039 controls, survival time of 1006 ESCC patients (survival GWAS) and gene expression (expression quantitative trait loci, eQTL) in 94 ESCC patients. Moreover, this database also provides the associations between 8833 somatic mutations and survival time in 675 ESCC patients. Our user-friendly database is a resource useful for biologists and oncologists not only in identifying the associations of genetic variants or somatic mutations with the development and progression of ESCC but also in studying the underlying mechanisms for tumorigenesis of the cancer. CCGD-ESCC is freely accessible at http://db.cbi.pku.edu.cn/ccgd/ESCCdb.
