Clinical impact of surveillance for head and neck cancer in patients with esophageal squamous cell carcinoma

To evaluate the clinical impact of surveillance for head and neck (HN) region with narrow band imaging (NBI) in patients with esophageal squamous cell carcinoma (ESCC).METHODSSince 2006, we introduced the surveillance for HN region using NBI for all patients with ESCC before treatment, and each follow-up. The patients with newly diagnosed stage I to III ESCC were enrolled and classified into two groups as follows: Group A (no surveillance for HN region); between 1992 and 2000), and Group B (surveillance for HN region with NBI; between 2006 and 2008). We comparatively evaluated the detection rate of superficial head and neck squamous cell carcinoma (HNSCC), and the serious events due to metachronous advanced HNSCC during the follow-up.RESULTSA total 561 patients (group A: 254, group B: 307) were enrolled. Synchronous superficial HNSCC was detected in 1 patient (0.3%) in group A, and in 12 (3.9%) in group B (P = 0.008). During the follow up period, metachronous HNSCC were detected in 10 patients (3.9%) in group A and in 30 patients (9.8%) in group B (P = 0.008). All metachronous lesions in group B were early stage, and 26 patients underwent local resection, however, 6 of 10 patients (60%) in group A lost their laryngeal function and died with metachronous HNSCC.CONCLUSIONSurveillance for the HN region by using NBI endoscopy increase the detection rate of early HNSCC in patients with ESCC, and led to decrease serious events related to advanced metachronous HNSCC.

Analog-experiment analysis of ash-deposition monitoring model of boiler economizers in power plants

Ash deposition is a form of particulate fouling, and appears usually in boiler economizers. The ash deposition increases capital expenditure, energy input and maintenance costs. An analog experiment for monitoring ash deposition was performed from the analogous objective of a 410 t/h boiler economizer to verify the rationality and reliability of the ash-deposition-monitoring model presented in order to increase the security and economy in economizer running. The analog experiment platform is a tube-shell exchanger that conforms well to the conditions of a self-modeling area. The analog flue gas in the shell side is the heated air mixed with ash, and in the tube side the fluid is water heated by the flue gas. The fluid state in the water side and the flue gas side follows the second self-modeling area. A 4-factor-3-level orthogonal table was used to schedule 9 operation conditions of orthogonal experiment, with the 4 factors being heat power, flue gas velocity, ashes grain diameter and adding ashes quantity while the three levels are different values due to different position classes in every factor. The ash deposition thermal resistances is calculated by the model with the measure parameters of temperature and pressure drop. It shows that the values of the ash deposition thermal resistances gradually increase up to a stable state. And the experimental results are reliable by F testing method at α= 0.001. Therefore, the model can be applied in online monitoring of ash deposition in a boiler economizers in power plants and provides scientific decision on ash deposition prediction and sootblowing.

Erasing the Asian Longhorned Beetle with Determined Actions, but at High Costs--A Case Report

In 2012, an infestation of Asian Longhomed Beetle （ALB） was detected in Winterthur （Canton Zurich, Switzerland）. With more than 140 adult beetles and several hundred eggs and larvae, the infestation was by far the most extensive in Switzerland. Based on long-term experiences made in Braunau （Austria）, where the first ALB infestation in Europe occured, the beetle was fought with extensive actions： removal of all infested trees, preventive removal of potential host trees and installation of a focus- and a buffer zone. Transport of plant material out of these zones was banned and a close monitoring regime including specialised dogs put in place. As a result of these efforts, there were no adult beetles and only a few living larvae detected 2013. Neither larvae nor beetles were found in 2014. However, costs are high： 700,000 Swiss francs were spent in 2012 alone, not including hundreds of working hours spent by employees of the Canton Zurich. The previewed monitoring programme between 2013 and 2017 is estimated to cost another 2.8 million Swiss francs, if no more living beetles are detected. The experiences from Winterthur thus show that elimination of a relatively small ALB infestation with determined actions is likely possible in short time. However, the high costs demonstrate the need for strong boarder controls or alternative packaging materials for imports from infested regions （China）. In addition, a concept for small communities with limited resources is needed.

On-line Monitoring for Phosphorus Removal Process and Bacterial Community in Sequencing Batch Reactor

For efficient energy consumption and control of effluent quality, the cycle duration for a sequencing batch reactor (SBR) needs to be adjusted by real-time control according to the characteristics and loading of waste-water. In this study, an on-line information system for phosphorus removal processes was established. Based on the analysis for four systems with different ecological community structures and two operation modes, anaerobic-aerobic process and anaerobic-anaerobic process, the characteristic patterns of oxidation-reduction potential (ORP) and pH were related to phosphorous dynamics in the anaerobic, anoxic and aerobic phases, for determination of the end of phosphorous removal. In the operation mode of anaerobic-aerobic process, the pH profile in the anaerobic phase was used to estimate the relative amount of phosphorous accumulating organisms (PAOs) and glycogen accumulat-ing organisms (GAOs), which is beneficial to early detection of ecology community shifts. The on-line sensor val-ues of pH and ORP may be used as the parameters to adjust the duration for phosphorous removal and community shifts to cope with influent variations and maintain appropriate operation conditions.

Research on Mine Fan Speed Control System Based on the PLC control network

This paper designs a set of ventilation and dust removal in coal mine test device and PLC monitoring system. The ventilation and dust removal test device has a set of ventilation and dust removal functions, can automatically monitor air volume, air pressure, resistance and other performance parameters of ventilator and precipitator. The PLC monitoring system can remotely start and stop the variable frequency speed control on the ventilation machine and dust collector, and it can real-time monitor operation state, such as the running current and the parameters of ventilator and dust collector. The paper simulate and realize computer remote centralized monitoring of underground ventilation for mine ventilation system. The actual application shows that： the system is stable and reliable, simple operation, strong scalability.

Risk factors for delayed methotrexate elimination in pediatric patients with hematological malignancies: a retrospective analysis

Delayed elimination of methotrexate(MTX) is a major clinical concern in patients receiving high-dose MTX(HD-MTX) therapy. In the present study, we aimed to retrospectively explore the factors associated with MTX concentrations and elimination delay in pediatric patients with hematological malignancies. Cycles of HD-MTX therapy were categorized into the normal elimination group and delayed elimination group according to the serum MTX concentrations at 24(C) or 42 h(C) after the start of MTX therapy. Clinical characteristics associated with MTX concentrations and elimination delay were assessed by χ^(2) test, Fisher’s exact test, Mann-Whitney test, or Spearman’s correlation coefficient. Generalized Estimating Equations(GEE) were used to adjust for the clustering effects of multiple cycles in one patient and confounders. A total of 43 patients with 138 cycles of HD-MTX chemotherapy were included and evaluated in the current study. Dose, white blood cells(WBC), hemoglobin(HB), and blood urea nitrogen(BUN) were significantly correlated with MTX C(all P < 0.05). No significant correlations were noticed between baseline characteristics and MTX C. Delayed MTX elimination was observed in 34(24.6%) courses. Dose, WBC, HB, BUN, and concurrent infection were the significant risk factors for delayed MTX elimination(all P < 0.05). Our study identified several risk factors associated with MTX levels and elimination, which might be used to recognize patients with a high risk of delayed MTX elimination. However, the findings need to be confirmed in further large-scale studies.
