Objective:To investigate the effect of preoperative systemic inflammatory response index (SIRI) on prognosis in patients with resectable colorectal cancer.Methods:The clinical data of 355 colorectal cancer patients underwent radical resection from January 2018 to December 2022 in the Second Affiliated Hospital of Harbin Medical University were retrospectively analyzed. The basic information, pathological data and laboratory test results were recorded, and SIRI was calculated. The patients followed up to December 2023 or death, and the overall survival (OS) and disease-free survival (DFS) were recorded. The receiver operating characteristic (ROC) curve was drawn, the optimal critical value of SIRI in patients with colorectal cancer was determined according to the maximum Yoden index, and the patients were grouped based on this. Multivariate Cox regression analysis was used to analyze the independent risk factors of prognosis in patients with colorectal cancer. Kaplan-Meier survival curve was drawn, and the log-rank test was used for comparison.Results:ROC curve analysis result showed that the optimal critical value of SIRI was 0.99, and the area under the curve was 0.556. Among the 355 patients with colorectal cancer, SIRI<0.99 was in 229 cases (low SIRI group), and SIRI≥0.99 was in 126 cases (high SIRI group). There were no statistical difference in gender composition, age, body mass index (BMI), preoperative carcinoembryonic antigen, preoperative cancer antigen 19-9 (CA19-9), tumor location, T stage, N stage, tumor stage, degree of differentiation, tumor long diameter, lymphatic invasion, vascular invasion, operating time and intraoperative blood loss between two groups ( P>0.05). The incidence of anastomotic leakage in high SIRI group was significantly higher than that in low SIRI group: 20.6% (26/126) vs. 12.2% (28/229), and there was statistical difference ( P<0.05). The median follow-up time of 355 patients was 21.7 months. The mortality and recurrence rate in high SIRI group were significantly higher than those in low SIRI group: 28.6% (36/126) vs. 19.2% (44/229) and 13.5% (17/126) vs. 6.1% (14/229), and there were statistical differences ( P<0.05). Kaplan-Meier survival curve analysis result showed that the median OS and DFS in high SIRI group were significantly lower than those in low SIRI group (17.3 months vs. 23.3 months and 15.1 months vs. 21.9 months), and there were statistical differences ( P<0.05). Multivariate Cox regression analysis result showed that the tumor stage Ⅲ to Ⅳ, preoperative CEA>5 μg/L and SIRI>0.99 were independent risk factors of OS and DFS in patients with colorectal cancer (OS: HR = 2.447, 1.951 and 1.923; 95% CI 1.461 to 4.099, 1.266 to 3.456 and 1.003 to 2.655; P<0.05. DFS: HR = 2.982, 1.782 and 1.529; 95% CI 1.663 to 4.754, 1.147 to 2.651 and 1.198 to 2.021; P<0.05). Conclusions:The preoperative SIRI is an independent risk factor of prognosis in patients with colorectal cancer. The patients with low SIRI have longer postoperative OS and DFS. The preoperative SIRI has guiding value in the prognosis assessment and treatment selection in patients with colorectal cancer.

Objective To evaluate the relationship between nutritional parameters and the risk of venous thromboembolicism(VTE)in patients with tuberculosis so as to identify the risk factors and predictors of thrombosis and assist in the early identification of high-risk factors for VTE in patients with the pulmonary tuberculosis.Methods A total of 323 patients diagnosed with the pulmonary tuberculosis and hospitalized in Kunming Third People's Hospital from August 2021 to August 2023 were collected.According to the VTE risk assessment of non-operative patients,they were divided into the high-risk group and the low-risk group respectively with 116 and 207 in each group.The nutritional indicators with statistically significant differences between the two groups were screened by Lasso regression.Multivariate Logistic regression was used to screen the independent risk factors for high VTE risk in pulmonary tuberculosis patients,and a nomogram prediction model was constructed.The prediction model was evaluated by receiver operating characteristic curve(ROC),calibration curve,decision curve,and influence curve.Results Patients in the high-risk group were significantly older than those in the low-risk group(59 vs.41,P<0.001),hypertension,gender,and Type 2 diabetes did not differ significantly(P values were 0.084,0.724 and 0.488,respectively).9 variables were selected from the inter-group comparison and Lasso regression,including ALB,HCT,NRS2002 scores,HBDH,RDW-SD,RDW-CV,TG,CONUT scores,and NEFA.Multivariate Logistic regression analysis showed that ALB,NRS2002 scores,RDW-SD,and CONUT scores were independent influencing factors for the high risk of VTE scores in patients with tuberculosis(P<0.005).Area under the ROC curve showed that the AUC(0.892)for high-risk VTE scores in patients with the pulmonary tuberculosis was greater than that of ALB(0.803),NRS2002 score(0.735),RDW-SD(0.685),and CONUT score(0.774).Fitting prediction model:Logit(P):Y=0.433×NRS-0.136×ALB+0.411×CONUT score+0.072×RDW-SD-1.770,P=1/(1+e-Y)(Y:prediction index,P:prediction probability).Calibration curve showed that the model prediction tended to be consistent with the actual results(U:>0.05),and the decision curve and influence curve showed that the model can bring clinical benefits.Conclusion ALB,NRS2002 scores,RDW-SD,and CONUT scores are independent influencing factors for the high risk of VTE scores in patients with tuberculosis.They can guide the clinical practice,improve these indicators as soon as possible,reduce VTE scores,and reduce the thrombosis risk.At the same time,the prediction model performs well in the verification cohort,with its discrimination ability,calibration accuracy and clinical utility(decision curve analysis)all reaching a satisfactory level.

Objective:To describe the prevalence of perinatal death in Tongzhou District of Beijing,and to estimate the association between maternal periconceptional supplementation of folic acid or multiple micronutrients containing folic acid and perinatal mortality rate.Methods:A retrospective cohort study was conducted based on the maternal and child care system in Tongzhou District of Beijing.The subjects were 94 490 perinatal who were born during January 2013 to December 2018.The information on perina-tal outcomes and maternal periconceptional supplementation of folic acid or multiple micronutrients contai-ning folic acid were collected.The Poisson log-linear model was used to estimate the association between maternal periconceptional folic acid or multiple micronutrients supplementation and perinatal mortality rate.Results:The overall perinatal mortality rate was 2.71‰.The perinatal mortality rates for maternal nutrients supplementation containing folic acid and no supplementation during periconceptional period were 2.63‰ and 3.43‰,respectively,and the difference in rates was not statistically significant[crude risk ratio(cRR)=0.77,95％CI:0.54-1.14].After adjusting for potential confounding factors in-cluding ethnicity,age,education level,occupation,household registration,parity,numbers of fetuses,gestational age,pregnant with assisted reproductive technology,delivery year and pre-pregnancy body mass index,the rates remained not statistically significant[adjusted risk ratio(aRR)=0.93,95％CI:0.77-1.13].The perinatal mortality rates were 2.23‰ and 2.99‰ for pure folic acid and multi-nutrients supplements containing folic acid,respectively,and the difference in rates was statistically sig-nificant(cRR=1.34,95％CI:1.02-1.76).The rates difference remained statistically significant after adjusting for potential confounders(aRR=1.31,95％CI:1.06-1.62).Additionally,the peri-natal mortality rates differences among the non-supplementation group and the supplementation group with variate timing of initiation(pre-conception or post-conception)or frequency of supplementation(low-frequency or high-frequency)were not statistically significant,regardless of adjusting for confounders.Conclusion:The overall perinatal mortality rate was lower than the national average level in Tongzhou District of Beijing.Maternal periconceptional supplementation of pure folic acid or micronutrients contai-ning folic acid had no impact on perinatal mortality.The association between maternal periconceptional supplementation of multiple micronutrients containing folic acid and perinatal mortality rate need further research.

Objective:To investigate the changes of respiratory function and lung volume after bariatric surgery using spiral CT three-dimensional imaging technology.Methods:Using the prospective study method, the medical records of 30 subjects undergoing sleeve gastrectomy (LSG) in the Eighth Department of General Surgery, the Second Hospital of Hebei Medical University from Jan. 2023 to Jun. 2024 were collected. Among them, 12 were males and 18 were females, aged from 20 to 45 years, with the average age of 31.1 years old. Chest CT scans were completed within 1 week before surgery and 6 months after surgery. The subject′s CT plain scan reconstructed thin-layer images of the mediastinal window were transferred to a GE workstation, and the lung volumes of both lungs and each lobe and the tracheal wall area of the five bronchial segments (RB1, RB4, RB10, LB1 + 2 and LB10) were calculated as a percentage of the airway cross-sectional area (WA%), and the posterior intercostal position corresponding to the diaphragm was recorded. Paired t-test and rank-sum test were used to compare preoperative and postoperative differences.Results:Compared with pre-operation, the subject′s body mass index decreased significantly 6 months after bariatric surgery [(42.22±7.31) kg/m 2vs (30.12±5.59) kg/m 2,t=7.31, P<0.001)]. Except for left lower lobe [(1.15±0.23) L vs (1.27±0.24) L, t=1.97, P=0.054] and right middle lobe [(0.57±0.16) L vs (0.83±0.16) L, t=1.38, P=0.172], the remaining lung parts were significantly larger after surgery than before surgery: right upper lobe [(0.80±0.17) L vs (0.94±0.19) L, t=2.79, P=0.007], right lower lobe [(1.08±0.14) L vs (1.22±0.19) L, t=3.23, P=0.002], left upper lobe [(1.12±0.20) L vs (1.24±0.23) L, t=2.26, P=0.014]. Overall, right lung volume [(2.44±0.33) L vs (2.79±0.41) L, t=3.62, P=0.001], left lung volume [(2.27±0.36) L vs (2.52±0.39) L, t=2.53, P=0.014] and total lung volume [(4.71±0.60) L vs (5.30±0.71) L, t=3.48, P=0.001] all increased significantly at 6 months after surgery compared with before surgery. All five segments of bronchus (WA%) were significantly reduced after surgery than before surgery: RB1: [(62.82±4.66) vs (66.85±3.99), t=3.60, P=0.001]; RB4: [(61.24±5.28) vs (64.31±5.51), t=2.20, P=0.031]; RB10: [(60.03±4.64) vs (62.97±5.73), t=2.18, P=0.033]; LB1+ 2: [(63.61±5.05) vs (67.90±4.30), t=3.54, P=0.001]; LB10: [(58.73±6.49) vs (62.01±5.06), t=2.17, P=0.034)]. The posterior intercostal position corresponding to the diaphragm dropped from an average of 7-8 intercostal spaces to 8-9 intercostal spaces, with a significant difference (rank mean 22.77 vs 38.23, Z=-3.67, P<0.001). Conclusion:Bariatric surgery can significantly reduce weight, reduce the pressure of chest and abdominal, improve lung compliance, reduce the internal pressure of the chest, lower the diaphragm, expand the lung volume and airway cross-sectional area, restore the original airway anatomy and respiratory physiology, so it can effectively improve the respiratory function and lung structure abnormalities caused by obesity.
