A sensing platform is presented for the determination of alkaline phosphatase (ALP) activity based on the cooperation of DNAzyme-Au spherical nucleic acid nanoprobe with the graphene-oxide-loaded hybridization chain reaction (HCR/GO) system to achieve good detection sensitivity and specificity. This assay takes advantage of the strong affinity of pyrophosphate (PPi) to Cu2+ ions and the fact that ALP can hydrolyze pyrophosphate (PPi) to release free Cu2+ ions. In the presence of ALP, the released Cu2+ can promote the Cu2+-dependent DNAzyme to cleave the substrate that generates a shorter DNA fragment, which is responsible for further triggering the HCR/GO system to form a long fluorescence dsDNA and thereby giving an amplified fluorescence signal. Linear calibration range was obtained from 0.2 to 10 U L-1, and the limit of detection (LOD) is about 0.14 U L-1. BGB-283 ic50 The feasibility of the proposed method was validated by spiking ALP standards in bovine serum. The recovery ranged from 97.2 to 104.6%, and a coefficient of variation (CV) of less than 8% (n = 3) was obtained. This assay strategy was also applied to evaluate the ALP inhibitor efficiency, which indicates that the assay has potential for drug screening.

The insufficient clearance of regional lymph nodes and unsatisfactory R0 resection rate may result in the metastasis of left-sided pancreatic ductal adenocarcinoma (PDAC) after conventional distal pancreatosplenectomy (CDPS). Radical antegrade modular pancreatosplenectomy (RAMPS) was designed to achieve R0 resection more successfully with better lymph-node clearance; however, there is still insufficient evidence of its short- and long-term results to confirm its superiority. We conducted this study to compare the efficiency of these two procedures.

The subjects of this retrospective analysis were 103 patients with left-sided PDAC who underwent either RAMPS (n = 46) or CDPS (n = 57). We assessed perioperative data and surgical information and used univariate and multivariate analyses to identify prognostic factors for survival.

There were no significant differences in baseline data between the groups. RAMPS was associated with a significantly shorter hospital stay (12.11days vs. 22.98days; P < 0.001), and significantly less blood loss (451.09ml vs. 764.04ml, P = 0.002), as well as a significantly lower rate of blood transfusion (15.22% vs. 33.33%, P = 0.035). RAMPS and CDPS had comparable perioperative complication rates. Moreover, RAMPS achieved more effective lymph-node retrieval (17.87 vs. 10.23; P < 0.001). The RAMPS group had a higher overall survival (OS) rate (28.73months vs. 18.30months; P = 0.003) and a higher disease-free survival (DFS) rate (21.97months vs. 9.40months; P < 0.001).

RAMPS achieved better survival and surgical outcomes than CDPS for patients with left-sided PDAC.

Delayed gastric emptying (DGE) is associated with prolonged hospital stay and higher healthcare costs. This study aimed to investigate the risk factors for DGE after D3 radical resection for colon cancer and to build a nomogram for this complication.

We analyzed, retrospectively, 1160 consecutive patients who underwent surgery with D3 lymphadenectomy for colon cancer between January, 2012 and June, 2018. A multivariate logistic regression analysis was used to identify the risk factors for DGE and to build a DGE nomogram model.

There were ten, six and four patients with DGE classified as grades A, B and C, respectively, representing a DGE rate of 1.7%. Multivariate analysis revealed that age (P = 0.001), dissection of the gastrocolic ligament lymph nodes (GCLNs) (P = 0.001), surgical duration (P = 0.017) and preoperative hemoglobin level (P = 0.016) were independent risk factors, and were included to build a predictive model for DGE. The therapeutic index of GCLN dissection was approximately half that of D3 lymphadenectomy (2.9 vs. 5.6).

DGE is more likely to develop in patients aged > 75years, those with a preoperative hemoglobin < 90g/L, those with a surgical duration > 210min, and those who undergo GCLN dissection. The nomogram may facilitate the stratification of patients at risk for DGE following D3 lymphadenectomy for colon cancer. Assessing long-term outcomes will help to evaluate the survival benefit of GCLN dissection in the future, to avoid unnecessary dissection and reduce the incidence of DGE.

Non-small-cell lung cancer (NSCLC) patients with interstitial lung disease (ILD) have a poor prognosis. The present study evaluated the prognostic impact of home oxygen therapy (HOT) in NSCLC patients with ILD.

Overall, 3099 consecutive patients underwent complete resection of stage IA to IIIA NSCLC at our institution between 2002 and 2016. ILD was diagnosed and categorized based on high-resolution computed tomography. The criteria for HOT included less than 90% resting oxygen saturation in the peripheral arteries and severe exertional dyspnea. We retrospectively compared the overall survival between ILD patients with and without HOT.

ILD was observed in 150 (5%) patients. Seventeen (11%) patients needed HOT at discharge. The incidences of usual interstitial pneumonia (UIP) pattern (p = 0.03) and blood loss (p < 0.01) were significantly higher in the patients requiring HOT than in those without HOT. Significantly more patients developed complications (p = 0.04) in the HOT group than in the non-HOT group, with three (18%) having acute exacerbations. The 3-year overall survival rate was significantly lower in the HOT patients than in those without HOT (28% vs. 63%, p = 0.03).

Patients requiring postoperative HOT showed a significantly poorer prognosis after complete resection than those without HOT. Therefore, the indication for surgery should be investigated cautiously in order to prevent the need for postoperative HOT.

To investigate the efficacy and safety of preemptive analgesia with a transversus abdominis plane (TAP) block versus celecoxib for patients undergoing laparoscopic transabdominal preperitoneal inguinal hernia repair (LTAPP).

Sixty patients scheduled for LTAPP were randomized into three groups a celecoxib group, given 200mg celecoxib 2h before surgery; a celecoxib/diclofenac group, given 200mg celecoxib 2h before surgery and 50mg rectal diclofenac sodium on recovery from general anesthesia; and a block group, given a TAP block with 60mL 0.25% levobupivacaine after general anesthesia. We assessed the numerical rating scale (NRS) scores for pain at rest and with movement 24h after surgery. Postoperative analgesia use and adverse events were also evaluated.

The NRS scores for pain at rest and with movement were lower in the celecoxib group than in the block group, 24h postoperatively. The time to first request for analgesia tended to be longer in the block group than in the celecoxib group. No significant between-group differences were noted in analgesic use or adverse events.

Celecoxib was not inferior to the TAP block as preemptive analgesia. Thus, celecoxib could be given as simple preemptive analgesia for LTAPP by considering a multimodal analgesic strategy in the early postoperative period.

To clarify the safety and effectiveness of continuing aspirin during the perioperative period of lung resection.

We analyzed, retrospectively, consecutive patients who underwent lung resection between 2008 and 2017. To investigate the safety of aspirin continuation, patients who continued taking aspirin perioperatively (Group C) were matched to other patients (Group O), using a propensity score, and bleeding outcomes were compared. To assess the effect of aspirin interruption, Group C was matched to a group of patients whose aspirin regimen was interrupted (Group I), and the postoperative complications related to thromboembolism were compared.

Among 3393 patients, 52 continued on aspirin (Group C) perioperatively, whereas 184 had their aspirin discontinued (Group I). Comparing the matched cohorts extracted from Group C and Group O (n = 45), there were no significant differences in bleeding outcomes. Comparing the matched cohorts extracted from Group C and Group I (n = 40), group C had fewer postoperative complications related to thromboembolism (0% vs. 7.5%, p = 0.039).

Bleeding complications did not increase by continuing aspirin, but thromboembolic complications increased when the aspirin regimen was interrupted during the perioperative period of lung resection. Thus, in the absence of a prohibitive bleeding risk, the continuation of aspirin during the perioperative period of lung resection appears to be desirable.

Hollow polymer nanospheres were fabricated from aniline, pyrrole, Triton-100, and ammonium persulfate via confined interfacial copolymerization reaction, which can be pyrolyzed to create HCNSs with the hollow gap diameter of about 20 nm under high temperature. Combining the synergistic effect of coordination and electrostatic interaction, Cu2+-HCNSs-COOH was constructed by anchoring Cu2+ on the surface of HCNSs-COOH. Furthermore, Cu2+-HCNSs-COOH has higher affinity for 3,3',5,5'-tetramethylbenzidine and H2O2 of 0.20 mM and 0.88 mM, respectively. Based on the rapid response of Cu2+-HCNSs-COOH to H2O2, we constructed a colorimetric sensing platform by detecting the absorbance of the 3,3',5,5'-tetramethylbenzidine-H2O2 system at 652 nm for quantifying H2O2, which holds good linear relationship between 1 and 150 μM and has a detection limit of 0.61 μM. We also investigated the degradation of MB in the presence of Cu2+-HCNSs-COOH and H2O2, which can degrade 80.7% pollutants within 30 min. This research developed an unusual nanozyme for bioassays and water pollution treatment, which broadened the way for the rapid development of clinical diagnostics and water pollution treatment.
