Objective To screen out significant differential genes for predicting the effect of neoadjuvant chemotherapy (NAC) and select the most suitable breast cancer patients for NAC. Methods A total of 60 breast cancer patients' samples before and after NAC were collected for high-throughput RNA-Seq. We selected AHNAK, CIDEA, ADIPOQ and AKAP12 as the candidate genes that related to tumor chemotherapeutic resistance. We analyzed the correlation of AHNAK, CIDEA, ADIPOQ, AKAP12 expression levels with the effect of NAC by logistic regression analysis, constructed a prediction model and demonstrated the model by the nomogram. Results AHNAK, CIDEA, ADIPOQ and AKAP12 expression were up-regulated in the residual tumor tissues of non-pCR group after NAC(P < 0.05). Compared with pCR group, non-pCR group presented higher expression levels of AHNAK, CIDEA, ADIPOQ and AKAP12 (P < 0.05). The high expression levels of AHNAK, CIDEA, ADIPOQ and AKAP12 significantly reduced the pCR rate of NAC for breast cancer (P < 0.05). Our prediction model which AHNAK, CIDEA, ADIPOQ and AKAP12 were involved in showed a good fitting effect with H1 test (χ²=6.3967, P=0.4945) and the ROC curve (AUC 0.8249, 95%CI: 0.722-0.9271). Conclusion AHNAK, CIDEA, ADIPOQ and AKAP12 may be novel marker genes for NAC effect on breast cancer. The efficacy prediction model based on this result is expected to be a new method to select the optimal patients of breast cancer for neoadjuvant chemotherapy.

Objective:To develop a three-dimensional body image stimuli suitable for middle-aged people in China, and verify the validity and reliability of the body image stimuli.Method:According to China and World Health Organization body mass index classification standards of adults, a set of three-dimensional body image stimuli of Chinese middle-aged males and females with different body size was developed by using 3D Studio Max and Adobe Photoshop CC based on the literature and expert consultation method. Forty-two 45- and 59-year-old middle-aged people in Zhengzhou City, Henan Province were recruited to verify the three-dimensional body image stimuli. Through questionnaire survey and physical examination, the coincidence between the selected body type and the actual body type was tested; the body composition was measured by dual-energy absorptiometry (DXA), and the structure validity of the image was tested; the body size satisfaction was investigated by the body image stimuli and the standard questionnaire, and the empirical validity of the image was tested. The repeated survey was conducted 14 days after the initial survey, and three experts were invited to score the current somatotype of the subjects to test the test-retest reliability and inter-rater reliability of the body image stimuli. Pearson, Spearman, Kendall correlation and Kappa consistency analysis were used to evaluate the validity and reliability of the body image stimuli.Results:The average age of 42 subjects was 52.7 years old, including 13 males and 29 females. A group of three-dimensional body image stimuli of middle-aged men and women were developed, and each group included 8 images. 73.8% of the subjects chose the body size consistent with the actual body type, and the weighted Kappa coefficient was 0.755 ( P<0.01). The selected somatotype was positively correlated with body weight and body composition indexes such as fat content, and the Pearson correlation coefficient of construct validity was 0.623-0.717 ( P<0.05). The results of the two surveys were positively correlated, and the Spearman correlation coefficient of test-retest reliability was 0.784-0.821 ( P<0.05). The scores of the three experts on the current somatotype of the subjects were positively correlated, and the Kendall correlation coefficient of inter-rater reliability was 0.818-0.878 ( P<0.05). Conclusion:The development of principle and reference basis of three-dimensional body image stimuli of middle-aged people is reliable, and the validity and reliability of the body image stimuli are good.

Objectives: To investigate the total fluids intake among college students in spring from Hebei. Methods: In March 2017, the subjects were recruited in a college in Baoding, Hebei Province. 156 students completed the investigation. Total drinking fluids was assessed by 7-day 24-hour fluid intake questionnaire, with a quantitative tool. The water from food was assessed by duplicate portion method. The sources of total fluids intake among subjects were analysed. Results: The age of subjects was (19.8±1.1) years old, including 80 male students. The median amounts of total fluids intake, total drinking fluids and water from food were 2 324, 1 135 and 1 174 ml, respectively. The proportions of total drinking fluids and water from food in total fluids intake were 51%±9% and 49%±10%. Only 19.9% (n=31) and 18.6% (n=29) of college students had adequate total fluids intake and total drinking fluids, according to the recommendation of China. The median amounts of total fluids intake, total drinking fluids and water from food were 3 210, 1 860 and 1 093 ml/d, respectively. The proportion of total drinking fluids in total fluids intake was 61%±7%, which were all higher than those who did not reach the recommended intake (2 158, 1 000, 1 149 ml/d; drinking fluids accounting for 46%±8% of total fluids intake) (P<0.05). Conclusion The amounts of total fluids intake and total drinking fluids of college students in Hebei Province are lower than the recommended intake in China. The contributions of total drinking fluids and water from food to total fluids intake were nearly same.

Objective: To investigate the food source of water of college students from Hebei Province in spring. Methods: In March 2017, the subjects were recruited in a college in Baoding, Hebei Province. 156 students completed the investigation. All foods were collected for 3 consecutive days using duplicate portion study combined with weighing method to test the water content of various foods. To analyze the water content of the food and calculate the proportion to the total amount of food water intake, the edible parts of each meal were divided into staple food, dishes, porridge, soup and snacks. Body mass index (BMI) was grouped according to quartiles, and the differences in food intake and food water sources among subjects of different genders and BMI were compared. Results: The age of subjects was (19.8±1.1) years old, including 80 male students. The median intake of staple food, dishes, porridge, soup and snacks per day was 562 g, 743 g, 111 g, 102 g and 0 g, respectively. The median intake of water from staple food, dishes, porridge, soup and snacks per day was 301 ml/d, 620 ml/d, 97 ml/d, 93 ml/d and 0 ml/d, respectively. The median ratio of water intake to total food water intake of staple food, dishes, porridge, soup and snacks was 27%, 53%, 8%, 8% and 0%, respectively. The median intake of water from staple food and dishes in male students was significantly higher than that of female students (P<0.05). The amount of water intake from porridge of female students was significantly higher than that of male students (P<0.05). There was no significant difference in the water intake from soup and snacks between different genders. There was no significant difference in food intake and food water sources among college students with different BMI (P>0.05). Conclusion The food source of water of college students from Hebei Province in spring is mainly based on dishes and staple foods. The food source of water for boys and girls is different.

Objectives: To investigate the total fluids intake, volume of urine and hydration status among college students from Hebei Province in spring. Methods: In March 2017, the subjects were recruited in a college in Baoding, Hebei Province. 156 students completed the investigation. Total drinking fluids was assessed by 7-day 24-hour fluid intake questionnaire, with a quantitative tool. The water from food was assessed by the duplicate portion method. The urine samples of 24-hour was collected for 3 consecutive days, and the volume, osmolality, pH and specific gravity of urine were measured. Hydration status was grouped to three types according to the urine osmolality (mOsm/kg), namely, optimal hydration (urine osmolality ≤500), middle hydration (500< urine osmolality ≥800) and dehydration (urine osmolality >800), and the differences among subjects in different genders and hydration statuses were compared. Results: The age of all subjects was (19.8±1.1) years old, including 80 male students. The median amounts of total fluids intake, total drinking fluids, water from food and urine volume were 2 324, 1 135, 1 174 and 1 279 ml/d, respectively. The volume of urine among males was 1 272 ml/d, which was not significantly different from that of females (1 304 ml/d) (P>0.05). The osmolality and specific gravity of urine among males were 688 mOsm/kg and 1.017, which were higher than those of females (493 mOsm/kg, 1.014) (P<0.05). But the pH of males was 6.6±0.3, which was lower than that of females (6.7±0.3) (P<0.05). Only 37.2% (n=58) of college students were in optimal hydration status. The median of the amount of total drinking fluids among subjects in optimal hydration status was 301, 448 ml/d higher than that in middle hydration status and dehydration, respectively (P<0.05). The proportion of females in optimal hydration status was 51.3% (n=39), which was higher than that of males 23.8% (n=19) (P<0.05). Conclusion Large proportion of college students in Hebei had lower total drinking fluids than the recommended intake of China, and the volume of urine was equal to the amount of total drinking fluids among the college students. Only 37.2% of college students were in optimal hydration status, and the proportion of female college students in optimal hydration status was larger than that of males.
