Abstract
3575 Background: The simultaneous resecting both colorectal cancer and liver metastases is a safety and efficacy surgical procedure for treating colorectal cancer patients with liver metastases (CRCLM).The safety and efficacy of robot-assisted simultaneous resection of CRCLM is unclear. Furthermore, what kind of selective CRCLM patients would obtain benefits from robotic procedure need identify. The aim of this study was designed to compare robotic procedure with open surgery, and establish robotic surgery indications to identify benefit population of CRCLM. Methods: CRCLM patients were evaluated and confirmed with surgical indication by multidisciplinary team (MDT), and randomized to two groups, robotic arm (n = 58) and open arm (n = 57). The primary endpoint is 3-year DFS, the second endpoints include short-term surgical outcomes, complications and safety. Results: A total of 115 patients were randomized between September 2013 and September 2016. Despite longer operating time, patients assigned to robot-assisted surgery had less blood loss (100ml vs. 150ml, P < 0.001), a shorter time to pass first flatus (3 d vs. 4 d, P < 0.001) and return to diet (3 d vs. 5 d, P = 0.002), shorter hospital stay with improved sexual function. Furthermore, followed benefits were observed in robotic arm versus open arm: lower serum C reactive protein (CRP) level on postoperative day 1 (POD1) (16 mg/L vs. 37 mg/L,P < 0.001), and POD3 (112 mg/L vs. 160 mg/L, P < 0.001), lower level of liver transaminase on POD5, and lower liver-related complication morbidity(10.3% vs 28.1%, p = 0.016). In addition, we identified and recommended selective CRCLM patients with the number of liver metastases < 3, maximal tumor size < 5cm, tumor not located in segment I to accept robotic procedure. Conclusions: We identified and recommended selective CRCLM patients to accept robotic surgery for treating liver metastases. Robotic surgery result in similar safety as open procedure, with shorter recovery time, decreased morbidity, and improved sexual function. Clinical trial information: NCT02642978.

Abstract
BACKGROUND Extracts from the leaves of Orthosiphon stamineus are used in phytotherapy for treatment of uncomplicated urinary tract infections. PURPOSES Evaluation of an aqueous extract against infection with uropathogenic Escherichia coli in vivo; investigation of underlying microbiological mechanisms. STUDY DESIGN In vivo studies in mice and in vitro investigations on cytotoxicity, antiadhesive potential, influence on bacterial gene expression and quorum sensing. METHODS Extract OWE was prepared by hot water extraction. For in vivo studies BALB/c mice were used in an UPEC infection model. The effect of OWE on bacterial load in bladder/kidney tissue was monitored in pre- and posttreatment. Cytotoxicity of OWE against different UPEC strains, T24 bladder/A498 kidney cells, gene expression analysis, monitoring of phenotypic motility and quorum sensing was investigated by standard methods of microbiology. RESULTS OWE was quantified (UHPLC) according to the content of rosmarinic acid, cichoric acid, caffeic acid. Three- and 5-day treatment of animals with OWE (750mg/kg) after transurethral infection with UPEC CFT073 reduced the bacterial load in bladder and kidney, similar to norfloxacin. Four- and 7-day pretreatment of mice prior to the infection with UPEC NU14 reduced bacterial bladder colonization. In vitro investigations indicated that OWE (≤2mg/ml) has no cytotoxic or proliferation-inhibiting activity against different UPEC strains as well as against T24 bladder and A498 kidney cells. OWE exerts a dose dependent antiadhesive activity against UPEC strains NU14 and UTI89. OWE reduced gene expression of fimH, but evoked increase of the expression of motility/fitness gene fliC. Increase of bacterial motility on gene level was confirmed by a changed bacterial phenotype by an increased bacterial motility in soft agar assay. OWE inhibited in a concentration-dependent manner bacterial quorum sensing. CONCLUSION OWE is assessed as a strong antiadhesive plant extract for which the traditional use in phytotherapy for UTI might be justified.

Abstract
Background A new staging system recently proposed by the IGCA has demonstrated a better capacity of stratifying different prognoses for gastric cancer than the 7th edition AJCC staging system (AJCC7). The aim of this study was to evaluate the efficacy of the IGCA system in Chinese patients. Methods Medical records of patients with gastric cancer who received curative surgery in our center from January 2003 to December 2011 were reviewed retrospectively. All the lesions were staged according to both AJCC7 and IGCA staging systems. Overall survival (OS) of the patients was used as the observation endpoint. Results One thousand five hundred twenty-six cases were included in this study. By comparing the AJCC7 system with the IGCA systems, 395 cases were stratified into different stages, most of which were in stage III. The IGCA system could better stratify stage IIIB and IIIC patients (5-year OS, 38.1% vs. 29.0%; P = 0.005) than the AJCC7 system (5-year OS, 38.2% vs. 35.9%; P = 0.148). T3N3bM0, T4aN2M0 and T4aN3bM0 made up 97.5% (385/395) of the stage shift. T3N3bM0, which was stratified to stage IIIB in the AJCC7 system, showed a significant poorer prognosis than T4aN2M0 and T4aN3aM0, which were staged to IIIB and IIIC in the same system. The improper staging was revised in the IGCA staging system. Conclusions The IGCA staging system can stratify stage III gastric cancer patients more properly than the AJCC7 system.

Int J Antimicrob Agents 2017; 49:579-588. [PMID: 28363526 DOI: 10.1016/j.ijantimicag.2017.01.010] [Citation(s) in RCA: 87] [Impact Index Per Article: 12.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/23/2016] [Revised: 12/22/2016] [Accepted: 01/06/2017] [Indexed: 12/17/2022]
Abstract
Ceftazidime/avibactam comprises the broad-spectrum cephalosporin ceftazidime and the non-β-lactam β-lactamase inhibitor avibactam. This phase 3, randomised, double-blind study (NCT01726023) assessed the efficacy and safety of ceftazidime/avibactam plus metronidazole compared with meropenem in patients with complicated intra-abdominal infection (cIAI) in Asian countries. Subjects aged 18-90 years and hospitalised with cIAI requiring surgical intervention were randomised 1:1 to receive every 8 h either: ceftazidime/avibactam (2000/500 mg, 2-h infusion) followed by metronidazole (500 mg, 60-min infusion); or meropenem (1000 mg, 30-min infusion). Non-inferiority of ceftazidime/avibactam plus metronidazole to meropenem was concluded if the lower limit of the 95% confidence interval (CI) for the between-group difference in clinical cure rate was greater than -12.5% at the test-of-cure (TOC) visit (28-35 days after randomisation) in the clinically evaluable (CE) population. Safety was also evaluated. Of 441 subjects randomised, 432 received at least one dose of study medication (ceftazidime/avibactam plus metronidazole, n = 215; meropenem, n = 217). In the CE population at the TOC visit, non-inferiority of ceftazidime/avibactam plus metronidazole to meropenem was demonstrated, with clinical cure reported for 93.8% (166/177) and 94.0% (173/184) of subjects, respectively (between-group difference, -0.2, 95% CI -5.53 to 4.97). The clinical cure rate with ceftazidime/avibactam plus metronidazole was comparable in subjects with ceftazidime-non-susceptible and ceftazidime-susceptible isolates (95.7% vs. 92.1%, respectively). Adverse events were similar between the study groups. Ceftazidime/avibactam plus metronidazole was non-inferior to meropenem in the treatment of cIAIs in Asian populations and was effective against ceftazidime-non-susceptible pathogens. No new safety concerns were identified.

Abstract
The effects of paracrine action from early activated hepatic stellate cells (HSCs) on resident liver epithelium cells are not clear. Here, we investigated whether a systemic infusion of early activated HSC-derived paracrine factors (HSC-CM) would evoke an enhanced liver protective response in acetaminophen (APAP)-induced acute liver injury (ALI) in mice and explored the possible underlying mechanisms. The survival rate, liver injury, and liver regeneration were analyzed in mice with or without HSC-CM treatment in vivo. A systemic infusion of HSC-CM provided a significant survival benefit in APAP-induced ALI. HSC-CM therapy resulted in a reduction of hepatocellular death and increased numbers of both proliferating hepatocytes and adult hepatic progenitor cells (AHPCs) with up-regulation of liver regeneration relevant genes. The HSC-CM treatment reduced leukocyte infiltration and down-regulated systemic inflammation with decreases in IFN-γ, IL-1ra, IL-1β, TNF-α, and increases in IL-10. The direct anti-death and pro-regeneration effects of HSC-CM on AHPCs were demonstrated using in vitro assays. Treatment with HSC-CM promoted AHPCs proliferation and resulted in increased pAkt expression in vitro, and this effect was abolished by the PI3K/Akt inhibitor LY294002. These data provide evidence that early activated HSC-CM therapy offered trophic support to the acutely injured liver by inhibiting liver cell death and stimulating regeneration, potentially creating a new method for the treatment of ALI.

Abstract
Postoperative complications after gastric cancer surgery has their own specificity and complexity, and the strategies for prevention and treatment should be of equal emphasis on both theory and technology. Based on the knowledge and familiarity with different postoperative complications, to efficiently prevent them, it is not only necessary to strengthen the training of acknowledged operative strategy, smooth and precise surgical techniques, but also to address the importance of overall preoperative assessment for patients, to treat the basic diseases, and to improve and correct their general conditions. Combining with the concept and basic protocol of enhanced recovery after surgery (ERAS), it is preferred to work out an individualized perioperative preventing strategy for patients who have high risk factors of specific postoperative complications. After the operation, to guarantee intensive and individual managements for patients, to catch early abnormal signs, then to make early and precise diagnosis, and to do timely response and accurate treatments, including timely and proper re-operations, can improve the efficacy of complications and promote the recovery of patients as soon as possible.

Abstract
Objective: To elucidate the effect of taurine on neurotoxicity induced by Mn by investigating activities of Na(+)-K(+)-ATPase and Ca(2+)-Mg(2+)-ATPase and content of Mn and active calmodulin in manganese exposed rats. Methods: 156 male SD rats were randomly divided into 1 control group, 3 manganese exposed groups (10, 15, and 20 mg/kg respectively) , and 9 taurine intervened groups based on orthogonal design (doses of taurine intervention were 100, 150, and 200 mg/kg respectively) , with 12 rats in each group. After 12 weeks of exposure, all rats were decapitated and corpus striatums were removed, activities of Na(+)-K(+)-ATPase and Ca(2+)-Mg(2+)-ATPase and content of Mn and active calmodulin were analyzed. Results: The corpus striatum Mn content of the 3 dose groups exposed to Mn and 9 taurine intervened groups were significantly higher than that of the control group (P<0.05) . Active calmodulin content in 10 mg/kg manganese exposed group was significantly higher than that of the control group (P<0.05) . 150 and 200 mg/kg of taurine could decrease active calmodulin content of the group exposed to 10 mg/kg of Mn (P<0.05) . The corpus striatum activities of Na(+)-K(+)-ATPase and Ca(2+)-Mg(2+)-ATPase of the 3 dose groups exposed to Mn were significantly lower than that of the control group (P<0.05) . 150 mg/kg of taurine could increase activities of Na(+)-K(+)-ATPase of the group exposed to 10 mg/kg of Mn (P<0.05) . 150 and 200 mg/kg of taurine could respectively improve activities of Ca(2+)-Mg(2+)-ATPase of the group exposed to 15, 10 mg/kg of Mn (P<0.05) . Conclusion: Mn can decrease the rats corpus striatum activities of Na(+)-K(+)-ATPase and Ca(2+)-Mg(2+)-ATPase, effect level of active calmodulin in relation to dose of Mn, to a certain extent, taurine could regulate activities of Na(+)-K(+)-ATPase and Ca(2+)-Mg(2+)-ATPase and improve the level of active calmodulin.

Abstract
Previous studies have reported that preoperative neutrophil-to-lymphocyte (NLR) and platelet-to-lymphocyte ratios were prognostic for various types of cancers. The aim of this study was to investigate the predictive utilities of preoperative peripheral blood counts in patients with gastrointestinal stromal tumors (GISTs). We enrolled 510 consecutive, previously untreated patients who underwent surgery for primary, localized GISTs. The relationship between recurrence-free survival and outcome variables was assessed by univariate and multivariate analyses, while the clinicopathologic relevance of NLR was determined using the Chi-square test. A preoperative NLR ≥2 was associated with poor prognosis in patients undergoing surgeries for primary, localized GISTs. It was an independent predictor only in patients classified as National Institutes of Health high risk but not in the entire population. Preoperative NLR is a feasible and reproducible peripheral biomarker that helps identify patients for intensive adjuvant therapy and frequent surveillance.

Abstract
A highly integrated, high performance, and re-configurable device, which is designed for the Nitrogen-Vacancy (N-V) center based quantum applications, is reported. The digital compartment of the device is fully implemented in a Field-Programmable-Gate-Array (FPGA). The digital compartment is designed to manage the multi-function digital waveform generation and the time-to-digital convertors. The device provides two arbitrary-waveform-generator channels which operate at a 1 Gsps sampling rate with a maximum bandwidth of 500 MHz. There are twelve pulse channels integrated in the device with a 50 ps time resolution in both duration and delay. The pulse channels operate with the 3.3 V transistor-transistor logic. The FPGA-based time-to-digital convertor provides a 23-ps time measurement precision. A data accumulation module, which can record the input count rate and the distributions of the time measurement, is also available. A digital-to-analog convertor board is implemented as the analog compartment, which converts the digital waveforms to analog signals with 500 MHz lowpass filters. All the input and output channels of the device are equipped with 50 Ω SubMiniature version A termination. The hardware design is modularized thus it can be easily upgraded with compatible components. The device is suitable to be applied in the quantum technologies based on the N-V centers, as well as in other quantum solid state systems, such as quantum dots, phosphorus doped in silicon, and defect spins in silicon carbide.

Abstract
Knowledge of the rigidity dependence of the boron to carbon flux ratio (B/C) is important in understanding the propagation of cosmic rays. The precise measurement of the B/C ratio from 1.9 GV to 2.6 TV, based on 2.3 million boron and 8.3 million carbon nuclei collected by AMS during the first 5 years of operation, is presented. The detailed variation with rigidity of the B/C spectral index is reported for the first time. The B/C ratio does not show any significant structures in contrast to many cosmic ray models that require such structures at high rigidities. Remarkably, above 65 GV, the B/C ratio is well described by a single power law R^{Δ} with index Δ=-0.333±0.014(fit)±0.005(syst), in good agreement with the Kolmogorov theory of turbulence which predicts Δ=-1/3 asymptotically.

Abstract
OBJECTIVE To investigate the efficacy of targeted therapy combined with surgery in the treatment of recurrent and metastatic gastrointestinal stromal tumor(GIST). METHODS Clinicopathological and followed-up data of 318 patients with recurrent and metastatic GIST admitted in Zhongshan Hospital between January 2000 and December 2015 were analyzed retrospectively. According to different treatment methods, the patients were divided into four groups: surgery group (operation alone, 44 cases), target therapy group (imatinib alone, 108 cases), target therapy combined with surgery group (imatinib plus operation, 139 cases), other therapy group (chemotherapy, Chinese medicine and others, 27 cases). The progression-free survival (PFS) and overall survival (OS) of four groups were compared. RESULTS The baseline informations, such as age, gender, primary site, et al, were not significantly different (all P>0.05), but the recurrent and metastatic site was significantly different among 4 groups (P=0.000). The medial PFS of surgery group, target therapy group, target therapy combined with surgery was 16(95%CI: 4.9 to 27.0) months, 44 (95%CI: 30.9 to 57.1) months, 35 (95%CI: 26.5 to 43.5) months, respectively, and the latter 2 groups had significantly longer PFS than surgery group(P=0.000), while no significant difference was found between target therapy group and target combined with surgery group (P=0.251). The median OS of surgery group, target therapy group, target therapy combined with surgery, and other therapy group was 24 (95%CI: 9.0 to 39.0) months, 69(95%CI: 40.8 to 97.2) months, 92(95%CI: 78.0 to 106.0) months, 12(95%CI: 9.5 to 14.5) months. Target therapy group and target therapy combined with surgery group had significantly longer OS than surgery and other therapy groups (P=0.000), while the target therapy combined with surgery group had significantly longer OS than target therapy group(P=0.028). CONCLUSION Target therapy combined with surgery can prolong the survival of recurrent and metastatic GIST patients.

Epigenetic silencing of miR-137 induces drug resistance and chromosomal instability by targeting AURKA in multiple myeloma. Leukemia 2016; 31:1123-1135. [PMID: 27857131 DOI: 10.1038/leu.2016.325] [Citation(s) in RCA: 58] [Impact Index Per Article: 7.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/07/2016] [Revised: 07/26/2016] [Accepted: 09/01/2016] [Indexed: 12/12/2022]
Abstract
Multiple myeloma (MM) is the second most prevalent hematologic malignancy. Aberrant microRNAs (miRNAs) expression has been shown to be involved in the pathogenesis of MM. In this study, we further demonstrated that miR-137 was significantly downregulated in MM and negatively correlated with clinical prognosis. Moreover, we described the epigenetic regulation of miR-137 and its association with progression-free survival in MM patients. Furthermore, overexpression of miR-137 in MM cell line (miR-137 OE) increased its sensitivity to bortezomib and eprirubicin in vitro. Also, some high-risk genetic abnormalities in MM, including deletion of chromosome 1p22.2, 14q or 17p13, and gain of chromosome 1p22.2 were detected in NCI-H929 empty vector (NCI-H929 EV) treated cells but not in the NCI-H929 miR-137 overexpression (NCI-H929 miR-137 OE) cells. Luciferase reporter assays demonstrated that miR-137 targeted AURKA. Ectopic expression of miR-137 strongly reduced the expression of AURKA and p-ATM/Chk2 in MM cells, and increased the expression of p53, and p21. Importantly, miR-137 overexpression together with bortezomib treatment significantly inhibited tumor growth in MM xenograft model. Taken together, this study demonstrates that miR-137 is epigenetically silenced in MM, and overexpression of miR-137 could reduce drug resistance and overcome chromosomal instability of the MM cells via affecting the apoptosis and DNA damage pathways.
