Objective To investigate the clinical effects of gastrointestinal decompression with enteral feeding tube in elderly patients with gastric cancer.Methods 78 cases of gastric cancer patients undergoing postoperative gastric decompression with enteral feeding tube were selected as the treatment group,and 66 patients with gastric cancer undergoing postoperative intravenous nutrition and gastric decompression with routine nasogastric tube as the control group in our hospital from January 2015 to December 2015.The incidence rate of gastric tube patency,faster postoperative recovery,nutritional immune improvement,adverse reaction and complication were compared between the two groups.Results The incidence rate of adverse reactions and complications in treatment group were significant lower than in control group (3.0 ％ vs.12.8 ％,x2 =4.4857,P =0.0342;1.5 ％ vs.10.2％,x2 =4.6620,P =0.0308,respectively).Following parameters were significant better in treatment group versus in control group:the time of evacuating [(3.1 ± 0.3) d vs.(4.0 ± 0.1) d,t =24.9227,P =0.0000],defecation[(4.3 ± 0.6) d vs.(5.5 ± 1.1) d,t =7.9189,P =0.0000],extubation [(5.3±1.3)d vs.(10.1±2.2)d,t=15.5690,P=0.0000],hospitalization[(12.3±2.5)d vs.(18.6± 3.2)d,t=12.9864,P=0.0000],postoperative body weight[(57.2±4.9)kg vs(49.0±7.2)kg,t=-7.8408,P=0.0000],plasma protein[(133.2± 11.2)g/L vs(104.5± 10.3)g/L,t=-16.0055,P=0.0000],hemoglobin[(4.7 ± 1.0) g/L vs (3.2 ± 0.6) g/L,t =-11.0991,P =0.0000] and peripheral blood lymphocyte count[(3.5 ± 0.7) × 109/L vs (2.1 ± 0.4) × 109/L,t =-15.0088,P =0.0000].Conclusions Effects of postoperative gastrointestinal decompression in elderly patients with gastric cancer are similar between with routine gastric tube and with enteral feeding tube.However,the enteral feeding tube-induced enteral nutrition shows fewer side effects and complications,better nutritional and immune effects,and faster postoperative recovery,which is worthy of a generalization and application.

Objective To investigate and analyze the social and psychological factors in late pregnancy among women with perinatal depressive disorder (PDD) and construct a predictive model for PDD Methods A total of 88 women diagnosed with PDD were selected as study group, and another 88 healthy women with normal prenatal care were selected as control group in a ratio of 1 to 1. General information and prenatal social and psychological factors related to the two groups were collected. Univariate and multivariate Logistic regression analysis was performed to construct a predictive model for PDD and assess its predictive efficacy. Results Univariate and multivariate Logistic regression analysis showed that gestational age, menstrual mood, history of adverse pregnancy, gender discrimination against women, gender discrimination by parents-in-law, income satisfaction, and depression history in paternal and maternal lineage and three generations were independent influencing factors for PDD in women (P<0.05). Based on these factors, a predictive model for PDD in women was constructed, the model equation was \begin{document}$P=\frac{1}{1+e-\operatorname{logit}(P)}$\end{document}, logit(P)=1.599×gestational age+1.744×poormenstrual mood+0.837×adverse pregnancy history+1.589×gender discrimination against women + 0.820×gender discrimination by parents-in-law+1.089×dissatisfaction with income+2.163×depression history in paternal and maternal lineage and three generations-3.211. The receiver operating characteristic curve showed that the area under the curve for predicting PDD in women using this model was 0.955, with a 95%CI of 0.907 to 0.998, a sensitivity of 0.964, and a specificity of 0.731. The optimal cutoff value was 5.154. Conclusion Gestational age, menstrual mood, adverse pregnancy history, gender discrimination against women, gender discrimination by parents-in-law, income satisfaction, and depression history in paternal and maternal lineage and three generations are independent influencing factors for PDD in women. The predictive model constructed based on these factors has good predictive efficacy for PDD in women, which can contribute to the early prevention and treatment of PDD.
