Objective: The goal of this research was to explore the relationship among attachment to parents,perceived academic achievement and self-esteem in high school students. Methods: High school students from four areas completed the following four questionnaires: Relationship Questionnaire(RQ),Experiences in Close Relationships Inventory(ECR),Self-esteem(SES) and Perceived Academic Achievement. Results: ①The scores of perceived academic achievement in students with attachment preoccupied to father were significantly lower than those with attachment dismissed to father. ②Attachment avoidance to father,attachment anxiety to father and self-esteem were positive correlated to perceived academic achievement (r=0.195,0.166 and 0.325). ③Attachment avoidance could predict the scores of perceived academic achievement. Conclusion: There are close relationship between adult attachment to father and perceived academic achievement,and self-esteem.

Objective To target the disease gene of disseminated superficial form of porokeratosis (DSP) in a six-generation of a Chinese family including a total of 254 family members in Shandong province. Methods The clinical data and the peripheral blood samples were collected in the pedigree members. The genomic DNA was extracted from the blood samples. A genome-wide scan was performed using 382 pairs of primers labelled with fluorescent stain. The primers were designed for human autosomes. The sequencing results were analyzed by the software of Genescan and Genotype. Linkage analysis was processed by Linkage software package to define the region of disease gene. For fine targeting the disease gene, other 10 micro-satellite markers for the above region were set up for further fine sequencing. Results We obtained the maximum two-point LOD scores of 3.06 at micro-satellite marker D12S78 (recombination fraction ? = 0.00). After fine mapping, the DSP gene is located within a 38.5 cM region between markers D12S326 and D12S79. Conclusion The DSP gene is mapped to chromosome 12q21.2~24.2.

Objective: To investigate the effect of postoperative precision nutrition therapy on postoperative recovery (PR) of patients with advanced gastric cancer (AGC) after neoadjuvant chemotherapy (NC). Methods: 71 subjects were randomly divided into 2 groups. The 34 patients of research group were treated with postoperative precision nutrition treatment according to the indirect energy measurement method. The 31 patients of control group were treated with traditional postoperative nutrition treatment. All participants were measured for body mass index (BMI), NRS2002, PG-SGA and relevant laboratory test within the 1st day before surgery and 7th day after surgery. Moreover, the difference between two groups in short-term effects were evaluated. Results: The daily energy supply of control group was 30.1%-43.74% higher than that of the experimental group (P<0.05). The resting energy expenditure (REE) of the research group after surgery was lower than that before operation. The levels of prealbumin, albumin and lymphocyte count were higher in research group than the controls at the 7th day after surgery whereas the opposite was true for the creatinine, urea nitrogen, C-reactive protein and procalcitonin (P<0.05). Similarly, the rate of malnutrition and nutritional risk became lower in the research group (P<0.05). The gastrointestinal function recovery of patients in the research group was comparable to that of the control group (P>0.05). Moreover, the complication rate and hospitalization costs of in research group were significantly lower than that of in control group (P<0.05). For patients with or without nutritional risks before surgery, the nutritional index and inflammatory index in the research group were better than those in the control group. Conclusion Postoperative precision nutrition therapy may improve the postoperative nutritional status and short-term effects of patients with AGC after NC.
