Objective:To investigate the prognostic value of systemic inflammatory score (SIS) in prognostic assessment of patients with unresectable metastatic colorectal cancer (mCRC).Methods:The clinical data of 130 patients with unresectable mCRC in Affiliated Haikou Hospital of Xiangya Medical College of Central South University from January 2014 to December 2016 were retrospectively analyzed. The relationship between SIS and clinicopathological characteristics of unresectable mCRC patients was also analyzed. The survival analysis was made by using Kaplan-Meier. The risk factors affecting the prognosis of unresectable mCRC patients were analyzed by using Cox regression model to make univariate and multivariate analysis.Results:According to SIS results, patients were divided into 0-score group (40 cases), 1-score group (58 cases), and 2-score group (32 cases). There were no significant differences in different SIS constitution patients stratified by age, gender, primary tumor location, functional status score, tissue type, RAS gene status, number of metastatic organs, peritoneal spread and molecular targeted therapy (all P > 0.05). Kaplan-Meier survival analysis showed that the 5-year overall survival rates of SIS 0-score, 1-score and 2-score group were 37.5%, 19.0%, 6.3%, respectively; and the difference was statistically significant ( χ2 = 3.152, P<0.01). Cox regression survival analysis showed that female, primary tumor location in right side and SIS (scores of 1-2) were independent risk factors for overall survival in patients with unresectable mCRC (all P<0.05). Conclusion:SIS may be an important indicator for prognostic assessment of patients with unresectable mCRC, and patients with high SIS have poor prognosis.

Objective:To analyze the risk factors of first endotracheal extubation failure and the related poor outcomes of extubation failure in intubated very low birth weight (VLBW) and extremely low birth weight (ELBW) infants.Methods:The VLBW/ELBW infants intubated in the first 24 hours, and admitted from June 2016 to December 2017 in Neonatal Intensive Care Unit of the Children′s Hospital of Fudan University were recruited in the study, and they were divided into 2 groups of the extubation-failure group and the extubation-success group based on whether being reintubated in 72 hours after the extubation.The clinical data of all children were collected, and risk factors and the short-term outcomes were compared between the 2 groups.Results:One hundred and twenty-six VLBW/ELBW infants including 25 extubation-failure infants and 101 extubation-success infants were recruited, the extubation fai-lure rate was 19.8%.Extubation-failure infants had lower gestational age and lower birth weight compared with those of extubation-success group [gestational age: (27.9±2.1) weeks vs.(28.9±1.6)weeks; birth weight: 990(847-1 200) g vs.1 170(1 060-1 350) g], and the differences were statistically significant (all P<0.05). The multiple Logistic analysis demonstrated that lower gestational age was the independent risk factor of extubation failure( OR=0.92, 95% CI: 0.86-0.99, P<0.05). The outcome analysis showed that the combined outcomes of moderate-to-severe bronchopulmonary dysplasia(BPD) and death in the extubation-failure group were significantly higher than those in the extubation-success group ( OR=3.33, 95% CI: 1.28-8.63, P<0.05)after being adjusted by gestational age.The secondary outcomes of brain magnetic resonance imaging(MRI) abnormality rate in the extubation-failure group was significantly higher compared with the extubation-success group ( OR=3.93, 95% CI: 1.22-12.60, P<0.05), and the mechanical ventilation duration was significantly longer as well in the extubation-failure group compared with that in the extubation-success group[10.1 d (6.9 d, 20.9 d) vs.3.6 d(1.1 d, 8.6 d)], and the difference was statistically significant( P<0.05). The rest secondary outcomes were not significantly different between the 2 groups(all P>0.05). Conclusions:A high rate of extubation failure in VLBW/ELBW infants was a common issue, and the lower gestational age is the independent risk factor for extubation failure.Extubation failure potentially increases the risk of moderate-to-severe BPD or death in VLBW/ELBW infants.

Objective:To explore the risk factors of lymph node metastasis (LNM) in early gastric cancer (ECG), and establish a risk-prediction model based on LNM.Method:Four hundred and twenty-seven EGC patients undergoing curative radical gastrectomy were enrolled in this study. The risk factors for LNM of ECG were analyzed with Logistic regression. LNM risk was stratified and risk-predicting model was established. The risk-predicting model was measured by area under ROC curve. According to the same standard, clinical data of 133 patients with EGC who underwent radical surgery were selected for external verification of the model.Results:The frequency of LNM was 13.3% (32/427) in EGC patients. The LNM ratio of intramucosal carcinoma and submucosal carcinoma was 1.3% (3/237), 15.3% (29/190) respectively. Ulcer presence, tumor size >2 cm, undifferentiated tumor, submucosal invasion, neural invasion, and vascular tumor thrombus were significantly associated with LNM in EGC patients ( χ2=3.408, 16.379, 4.808, 29.804, 25.305, 47.120, respectively P<0.05). Multivariate analysis suggested that ulcer presence, tumor size >2 cm, depth of invasion, neural invasion, and vascular tumor thrombus were independent predictors of LNM in EGC patients, ( OR=0.326, 2.924, 11.824, 13.047, 7.756, respectively P<0.05). LNM predicting model is established, P=e^x/(1+e^x),x=-4.792-1.122 ulcer presence+1.073 tumor size+2.470 depth of invasion+2.569 neural invasion+2.048 vascular tumor thrombus,ROC-AUC of risk-predicting model was 0.845, the best cut-off was 0.094, the sensitivity was 72.70%, the specificity was 77.20%. The external verification result revealed the AUC of ROC was 0.840. The four-grid table is constructed by predicting model results and the postoperative pathological examination. The sensitivity and specificity of the model are calculated to be 82.35% and 68.96%, respectively. Conclusions:EGC patients with ulcer presence, tumor size >2 cm, depth of invasion, vascular tumor thrombus, and neural invasion have higher risk of LNM, the risk-predicting model can identify the high probability of LNM .
