Fitting formulas of typical parameters were obtained through analysis of anthropometric parameters of armored car driver and operators. These formulas could be a basis for design of product and equipment of cars, cumulating and updating of basic data of similar sample and edition of relative standards. 76 anthropometric static parameters and 11 functional parameters were chosen, and 1 243 soldiers with armored forces were chosen to be tested. The correlation and fitting formulas of body height, sitting height and other parameters were measured and obtained. We also contrasted measured data with data from GJB1835-1993. The present analysis showed that the correlation between sizes of body length and body height and sitting height was significant. Sizes of body length and enclose size and width direction were all increased compared to those in the 1980s. The present results were consistent with other researchers' current research results. The measured data could be an important basis for the data of young male anthropometric parameters and edition of relative standards and design of specific equipment.

PURPOSE: The estimation of fluid deficit is crucial to the proper management of dehydrated children. Without well-documented serial weights on the same scale, the estimation of any given child's fluid deficit is imprecise and dependent largely on subjective clinical criteria. Despite the abundance of literature on clinical and laboratory evaluation of dehydration, few studies have focused on serum uric acid. So, we examined the usefulness of serum uric acid in gastroenteritis patients with dehydration. METHODS: Medical records of 90 gastroenteritis patients were retrospectively reviewed. By the body weight loss, we classified patients with mild, moderate, and severe dehydration groups. We studied the relevance of laboratory data (BUN, creatinine, serum bicarbonate, glucose, urine specific gravity, and uric acid) with dehydration. RESULTS: 54 children (60%) were dehydrated mildly, 24 (26%) dehydrated moderately, and 12 (14%) dehydrated severely. Statistically significant differences in BUN, creatinine, serum bicarbonate, glucose, and urine specific gravity could not be observed. But there was significant relationship between uric acid and the degree of dehydration. Data analysis suggested that the level of 7.0 mg/dL is the best cut-off value for predicting the development of moderate or severe dehydration. At this cut-off value, the sensitivity and specificity were 66.6% and 87.1%. CONCLUSION: Our study supports that the measurement of serum uric acid with traditional scales is useful for predicting the development of dehydration. But, in order to be used as the indicator for proper treatment at an earlier stage, further validation about serum uric acid is necessary.

OBJECTIVES: To compare the health behaviors of widowed women with those of currently married women. METHODS: We randomly sampled the subjects from the Jeollanamdo Resident Registration Data and we then selected 2,331 widowed women and 4,775 married women. Well-trained examiners measured the height, weight, blood pressure and abdomen circumference, and the women were interviewed with using a questionnaire. Logistic regression analysis was used to estimate the odds ratios(OR) of the two groups. RESULTS: The smoking rate (OR=2.46; 95% confidence interval [CI]1.65, 3.66) was significantly higher for the widowed women. On the contrary, the awareness rate of a smoking cessation campaign (OR=0.80; 95% CI=0.70, 0.92), a quit tobacco telephone line (OR=0.73; 95% CI=0.61, 0.88) and a quit smoking clinic (OR=0.74; 95% CI=0.62, 0.89) were lower for the widowed women. The rate of receiving a health exam (OR=0.80; 95% CI=0.70, 0.91), the rate of undergoing gastric cancer screening (OR=0.77; 95% CI=0.68, 0.88), breast cancer screening (OR=0.79; 95% CI=0.69, 0.89), cervix cancer screening in the last 2 years (OR=0.81; 95% CI=0.71, 0.92), colon cancer screening in the last 5 years (OR=0.74; 95% CI=0.63, 0.87) were significantly lower for the widowed women. CONCLUSIONS: This study revealed that the health behaviors are significantly different between the widowed women and the married women. To improve the health behaviors of the widowed women, further study and research that will investigate the socioeconomic and environmental factors that affect the health behaviors of widowed women will be needed.

OBJECTIVE: We evaluated the association between patients' weight and abdominal cross-sectional dimensions and CT image quality. MATERIALS AND METHODS: We prospectively evaluated 39 cancer patients aged more than 65 years with multislice CT scan of abdomen. All patients underwent equilibrium phase contrast-enhanced abdominal CT with 4 slices (from top of the right kidney) obtained at standard tube current (240 280 mA). All other scanning parameters were held constant. Patients' weight was measured just prior to the study. Cross-sectional abdominal dimensions such as circumference, area, average anterior abdominal wall fat thickness and, anteroposterior and transverse diameters were measured in all patients. Two subspecialty radiologists reviewed randomized images for overall image quality of abdominal structures using 5-point scale. Non-parametric correlation analysis was performed to determine the association of image quality with patients' weight and cross-sectional abdominal dimensions. RESULTS: A statistically significant negative linear correlation of 0.46, 0.47, 0.47, 0.58, 0.56, 0.54, and 0.56 between patient weight, anterior abdominal fat thickness, anteroposterior and transverse diameter, circumference, cross-sectional area and image quality at standard scanning parameters was found (p< 0.01). CONCLUSION: There is a significant association between image quality, patients' weight and cross-sectional abdominal dimensions. Maximum transverse diameter of the abdomen has the strongest association with subjective image quality.

To establish a fetal biparietal diameter (BPD)-gestational age formula based on the data of pregnant women from Xiaoshan District of Hangzhou, and to evaluate its application in prenatal screening.Data of 3500 pregnant women with gestational age between 15 weeks and 19 weeks+6 receiving prenatal screening in Xiaoshan Hospital during May 2014 and May 2015 were collected. BPDs were used to establish a localized BPD-gestational age formula. The localized formula was used to evaluate the prenatal screening risks in 1759 pregnant women with irregular menstrual cycles or uncertain last menstrual period (LMP) in Xiaoshan District, and the results were compared with those calculated using formula in LifeCycle 4.0.With localized formula, the total positive rate of Down syndrome, trisomy 18 syndrome and deformity of neural tube was decreased from 6.96% to 5.85% (<0.05), in which the positive rate of Down syndrome decreased (<0.05), that of deformity of neural tube increased (<0.05), and that of trisomy 18 syndrome remained the same (>0.05). The median MoMs of free-hCG β and α-fetoprotein calculated using localized formula were significantly different from those calculated using the formula in LifeCycle 4.0 (all<0.05), and the former ones were more closer to 1. For women of fetus diagnosed with the above diseases, the positive rate calculated using localized formula was almost the same as that calculated using the formula in LifeCycle 4.0.BPD-gestational age formula should be localized based on the statistical analysis of the local population, which will help to reduce the false positive rate, and make the results more accurate and reliable in prenatal screening.
