Objective To study the safety and short-term clinical outcome of different body mass index (BMI) patients with rectal cancer undergoing laparoscopic total mesorectal excision (TME). Methods The clinical data of 179 rectal cancer patients who had underwent laparoscopic TME from November 2016 to November 2017 were retrospectively analyzed. The patients were divided into 3 groups according to the BMI:leanness group (BMI<18.5 kg/m2, 15 cases), normal group (BMI 18.5 to 22.9 kg/m2, 89 cases) and overweight/obesity group (BMI ≥23.0 kg/m2, 75 cases). The general clinical data and the operation-related situation were compared. Results The rate of preoperative complications in overweight/obesity group was significantly higher than that in leanness group and normal group: 45.33%(34/75) vs. 4/15 and 28.09%(25/89), the preoperative albumin level in leanness group was significantly lower than that in normal group and overweight/obesity group:(36.3 ± 2.8) g/L vs. (38.6 ± 3.2) and (39.1 ± 3.7) g/L, and there were statistical differences (P<0.05). The operation time and blood loss in overweight/obesity group were significantly higher than those in leanness group and normal group: (149.2 ± 32.9) min vs. (129.3 ± 28.7) and (133.5 ± 23.6) min, (135.5 ± 29.0) ml vs. (117.5 ± 22.6) and (122.5 ± 25.9) ml, and there were statistical differences (P<0.05). There were no statistical differences in sex, age, tumor location, tumor maximum diameter, depth of tumor invasion, lymph node metastases, surgical approach, circumferential margin, number of lymph node dissections, length of resected specimens, incidence of postoperative complications, surgical site infection, postoperative urinary retention, postoperative exhaust time and postoperative hospitalization among 3 groups (P>0.05). Conclusions The differences of BMI mean different complications and nutritional status of patients. Overweight and obesity can lead to difficult operation of laparoscopic TME, but do not affect the radical cure of operations and the safety of clinical outcomes.

Objective:To investigate the safety of minimally invasive liver resection for resectable hepatocellular carcinoma (HCC) complicated with portal hypertension.Methods:The propensity score matching and retrospective cohort study was conducted. The clinicopathological data of 807 patients with resectable HCC who underwent minimally invasive liver resection in 8 medical centers, including Sir Run Run Shaw Hospital, Affiliated with the Zhejiang University School of Medicine et al, from June 2011 to November 2022 were collected. There were 670 males and 137 females, aged 58(50,66)years. Of the 807 patients, 173 cases with portal hypertension were divided into the portal hypertension group, and 634 cases without portal hypertension were divided into the non-portal hypertension group. Observation indicators: (1) propensity score matching and comparison of general data of patients between the two groups after matching; (2) intraoperative and post-operative situations; (3) subgroup analysis. Propensity score matching was done by the 1:1 nearest neighbor matching method, with the caliper setting as 0.001. Measurement data with skewed distribution were represented as M( Q1, Q3), and comparison between groups was conducted using the rank sum test. Count data were described as absolute numbers, and comparison between groups was conducted using the chi-square test or Fisher exact probability. Comparison of ordinal data was constructed using the non-parameter rank sun test. Results:(1) Propensity score matching and comparison of general data of patients between the two groups after matching. Of the 807 patients, 268 cases were successfully matched, including 134 cases in the portal hypertension group and 134 cases in the non-portal hypertension group. The elimination of the tumor diameter and robot-assisted surgery confounding bias ensured comparability between the two groups after propensity score matching. (2) Intraoperative and postoperative situations. The occlusion time of porta hepatis, cases with intraoperative blood transfusion, cases with postoperative complication, cases with complication >Ⅱ grade of Clavien-Dindo classification, cases of Clavien-Dindo classification as Ⅰ grade, Ⅱ grade, Ⅲ grade, Ⅳ grade, cases with liver related complication were 27.0(15.0,43.0)minutes, 33, 55, 15, 13, 29, 14, 1, 37 in the portal hypertension group, versus 35.0(22.0,60.0)minutes, 17, 25, 5, 14, 9, 4, 1, 13 in the non-portal hypertension group, showing significant differences in the above indicators between the two groups ( Z=-2.15, χ2=6.30, 16.39, 4.38, 20.72, 14.16, P<0.05). (3) Subgroup analysis. Results of subgroups analysis showed that in cases with major live resection, the operation time, volume of intraoperative blood loss, duration of postoperative hospital stay were 243.5(174.6,296.3)minutes, 200.0(150.0,600.0)mL, 7.5(6.0,13.0)days in the portal hypertension group, versus 270.0(180.0,314.5)minutes, 200.0 (75.0,450.0)mL, 7.0(5.5,10.0)days in the non-portal hypertension group, showing no significant difference in the above indicators between the two groups ( Z=-0.54, -1.73, -0.92, P>0.05). In cases with non-major live resection, the operation time, volume of intraoperative blood loss, duration of postoperative hospital stay were 170.0(120.0,227.5)minutes, 100.0(50.0,200.0)mL, 8.0(5.0,10.0)days in the portal hypertension group, versus 170.0(120.0,227.5)minutes, 100.0(50.0,200.0)mL, 7.0(5.5,9.0)days in the non-portal hypertension group, showing no significant difference in the above indicators between the two groups ( Z=-1.39, -0.10, 1.05, P>0.05). In cases with anatomical liver resection, the operation time, volume of intraoperative blood loss, duration of postoperative hospital stay were 210.0(150.0,285.0)minutes, 150.0(50.0,200.0)mL, 8.0(6.0,9.3)days in the portal hypertension group, versus 225.5(146.3,306.8)minutes, 100.0(50.0,250.0)mL, 7.0(6.0,9.0)days in the non-portal hypertension group, showing no significant difference in the above indica-tors between the two groups ( Z=-0.75, -0.26, -0.91, P>0.05). In cases with non-anatomical liver resection, the operation time, volume of intraoperative blood loss, duration of postoperative hospital stay were 173.5(120.0,231.5)minutes, 175.0(50.0,300.0)mL, 7.0(5.0,11.0)days in the portal hyper-tension group, versus 186.0(123.0,262.5)minutes, 100.0(50.0,200.0)mL, 7.0(5.0,9.5)days in the non-portal hypertension group, showing no significant difference in the above indicators between the two groups ( Z=-0.97, -1.12, -0.98, P>0.05). Conclusion:Minimally invasive liver resection or even major liver resection is safe and feasible for screened HCC patients complicated with portal hyper-tension, but attention should be paid to the prevention and treatment of postoperative complications.

Autism spectrum disorder (ASD) is one of the common neurodevelopmental disorders in children. Its etiology and pathogenesis are poorly understood. Previous studies have suggested potential changes in the complement and coagulation pathways in individuals with ASD. In this study, using multiple reactions monitoring proteomic technology, 16 of the 33 proteins involved in this pathway were identified as differentially-expressed proteins in plasma between children with ASD and controls. Among them, CFHR3, C4BPB, C4BPA, CFH, C9, SERPIND1, C8A, F9, and F11 were found to be altered in the plasma of children with ASD for the first time. SERPIND1 expression was positively correlated with the CARS score. Using the machine learning method, we obtained a panel composed of 12 differentially-expressed proteins with diagnostic potential for ASD. We also reviewed the proteins changed in this pathway in the brain and blood of patients with ASD. The complement and coagulation pathways may be activated in the peripheral blood of children with ASD and play a key role in the pathogenesis of ASD.
