Objective: To analyze the effect of breakfast nutrition quality on the satiety among young white-collar workers. Methods: A total of 278 subjects were recruited from two cities, Shenyang and Chongqing, in June 2015. The inclusion criteria: white-collar workers aged 25-45 years involved mainly in office work, who did not experience major changes, and individuals who should follow the study protocol and sign the informed consent form. The study employed a three-phase crossover design trial. Each participant received nutritional-adequate breakfast, nutritional-inadequate breakfast, and no breakfast treatment on the basis of assignment to one of three sequences. The breakfast time was once a week and then changed, all participants underwent the tests for three successive weeks. At last, we compared the effect of participants to consume different nutritional quality on satiety sense and hunger sense. Results: A total of 232 participants completed three successive breakfast intervention studies, the age of participants was (35.2 ± 7.9) years, comprised of 48.7% male (n=113). The numbers of participants of aged 25-35 year-old and aged 36-45 were 118 and 114, respectively. Satiety scores of nutrition-adequate breakfast group, nutrition-inadequate breakfast group and no breakfast group were 63.5±14.7, 53.1±10.2 and 36.4±7.2, respectively (P<0.05). In nutrition-inadequate breakfast group and no breakfast group, male subjects scored significantly higher than female subjects (50.9±10.5 vs 46.6±9.4, 35.2±8.3 vs 31.8±5.4) (P<0.05). And, participants aged 25-35 year-old. got satiety score significantly higher than aged 36-45 (51.3±11.0 vs 45.6±12.1, 34.1±6.8 vs 32.5±7.9), the difference was statistically significant (P<0.05). The scores of hunger in the group of nutrition-adequate breakfast, nutrition-inadequate breakfast and no breakfast were 26.3 ± 8.0, 35.1 ± 11.2 and 57.3 ± 17.0, respectively (P<0.05). Conclusion The nutrition quality of breakfast affects the satiety of young white-collar workers. The better the nutrition quality of breakfast is, the higher the satiety score and the lower the hunger score become. Compared with women and participants aged 36-45 year-old, men and those aged 25-35 year-old get satiety sense more easily.

Objective To establish a conventional intraocular lens (IOL) calculation formula which is applicable to eyeballs with abnormal data and laser in situ keratomileusis (LASIK) postoperative eyes.Methods A case-series study was adopted.According to the classical optical theory,a normal IOL implanted eye has the following characteristics:when light is refracted by cornea and arrives on the IOL plane,the value of refractive power (F1) + IOL refractive power (F2) =the value of refractive power which is suitable for vitreous body depth (F3).Thereafter,a mathematical model was built on the basis of theory,experience,and regression analysis data after IOL implantation surgeries.Furthermore,based on the new LASIK postoperative cornea curvature modified formula,the two kinds of IOL calculation programs of conventional and LASIK postoperative eyes were established.The test data was collected from 644 patients who had undergone the cataract extractions and IOL implantation surgeries (600 physiological cornea eyes,7 radial keratotomy [RK] eyes and 37 LASIK postoperative eyes) at the Affiliated Drum Tower Hospital of Nanjing University Medical School.Through the analysis of these data,the new formulas were examined.Results With IOL refractive power of 607 eyes (including 7 RK postoperative eyes),the average error of XLQ formula (the tentative name of the established formula in this study)was 0.1 D,and the 95％ limits of agreement range was-1.1 to + 1.2 D.The error range of IOL refractive power predicted by XLQ,SRK-T and Haigis formulas was-2.21 to +2.25 D,-5.10 to +5.63 D and-3.00 to +3.18 D,respectively,the absolute average error of IOL refractive power predicted by the three formulas was (0.43 ± 0.28),(0.74 ± 0.53) and (0.79 ± 0.49) D,respectively.Compared with SRK-T and Haigis formulas,the average error of IOL refractive power predicted by XLQ formula was Lower,with significant differences between them (both at P =0.000).The error value of IOL refractive power predicted by XLQ formula had no statistical correlations with axial length (AL),keratometry (K) and A constant respectively (all at P＞0.05),while the error value predicted by SRK-T and Haigis formulas had statistical correlations with AL,K and A constant,respectively (all at P＜0.05).Thirty-seven patients who had conducted LASIK for myopia (and whose IOL refractive power value were predicted by XLQ formula) had been undergone the postoperative examination.Comparing the predicted and actual value,the error range of IOL refractive power was-0.52 to +1.18 D,and the absolute average error was (0.49±0.26)D.Conclusions The conventional mode of the XLQ formula established in this study can be used in the cases with broad values of axial length,corneal curvature and A constant,as well as various types of physiological cornea and RK postoperative eyes;the dedicated mode is suitable for LASIK postoperative eyes of myopia.

Objective To investigate the influencing factors of the indwelling catheter time in patients with prostate hyperplasia and malignant tumor after prostate surgery.Methods A total of 447 prostate surgery patients with prostate hyperplasia and malignant tumor were selected for medical record review using convenience sampling method. The demographic data,diagnose,complications,surgical method,medical advice and nursing care items were collected. The indwelling catheter time in or outward of the hospital and its influence factors were analyzed.ResultsA number of 300(44.74%) patients had urination disorders before operation.A number of 258(57.72%) patients had complications. Little information about rehabilitated exercise of urination function was recorded.There were statistically significant differences in indwelling catheter time in the hospital among benign prostatic hyperplasia patients with different education levels, health payments and complications (t/F=5.048, -2.433, 2.086;P<0.05). Significant differences in indwelling catheter time outward of the hospital were also observed in patents with different preoperative urination disorders (t=0.551, P<0.05). Prostate malignancy patients with different resident places and bad habits had statistically significant differences in indwelling catheter time outward of the hospital (t=2.062, -1.974;P<0.05). For patients with benign prostatic hyperplasia, education levels, health payment and complications could explain 60.8% of changes in indwelling catheter time in the hospital. For patients with prostate malignancy, resident place and bad habits could explain 68.4% of changes in indwelling catheter time outward of the hospital. According to medical records, only 42.5% patients had urinary flow rate, urodynamic and residual urine volume examinations. Only 17.4% of medical records had urinary function related admission, which were found in 26.4% of medical records when patients were discharged.ConclusionsMedical workers are lack of attentions to the rehabilitated exercise of urination function for patients with prostate hyperplasia and malignant tumor after prostate surgery. It is urgent to build a scheme of rehabilitated exercise of urination function for postoperative patients of prostate, which based on the fast-track surgery theory and used the time as axis.
