Abstract
A good integration of dental implants and the surrounding soft tissue is essential to ensure the long-term effect of implant. In this review, we summarized the research progress of peri-implant soft tissue integration of dental titanium implants, with emphasis on the modification of the gingival interface of implants based on immune microenvironment regulation. This method influences the immune response around the implant by promoting the surface properties of implants, so as to enhance the peri-implant soft tissue integration. The purpose of this review is to provide reference for the related research and clinical application in the field of dental implantation.

Abstract
Sixteen patients with recurrent high-grade glioma who were treated by domestic magnetic resonance-guided laser interstitial thermotherapy (MRgLITT) in the Neurosurgery Department of Xuanwu Hospital of Capital Medical University from 1st January 2021 to 31st December 2021 were prospectively included, with 11 males and 5 females, and aged 27-74 (50±16) years. The duration of surgery, the rate of ablation after surgery, and perioperative complications were assessed. The patients were followed up every 3 months to assess survival and progression. A total of 5 WHO grade Ⅲ patients and 11 WHO grade Ⅳ patients were included. The operation time was 144 (109, 176) min, 28 targeted lesions were detected, and the ablation rate [M (Q1, Q3)] was 91.0% (87.4%, 93.3%). After surgery, 2 patients (2/16) had decreased limb muscle strength, and no perioperative death or other serious complications occurred. The median time to a complete response was 12 (5, 14) months in WHO Grade Ⅲ patients, and one died 12 months after surgery, while the median time to a complete response was 3 (1, 8) months in 11 WHO Grade Ⅳ patients, with a total of 8 deaths at the last follow-up. Therefore, domestic MRgLITT has certain efficacy and safety in the treatment of recurrent high-grade glioma, providing a new option for patients with recurrent glioma.

Abstract
Severe acute dichlorvos poisoning is characterized by rapid onset, swift disease progression and serious complications. It frequently involves multiple organ failure (central, respiratory and circulatory systems), severe acidosis, and rare occurrences of gastric perforation. When secondary gastric perforation occurs, treatment becomes difficult and the prognosis of patients is poor. Thus, early and sufficient gastrointestinal decontamination is crucial. This article presented two cases of gastric perforation secondary to dichlorvos poisoning and discussed the causes of gastric perforation, as well is clinical diagnostic and treatment methods.

Abstract
BACKGROUND Though the CXCR2 chemokine receptor is known to play a key role in cancer growth and response to therapy, a direct link between expression of CXCR2 in tumor progenitor cells during induction of tumorigenesis has not been established. METHODS To characterize the role of CXCR2 during melanoma tumorigenesis, we generated tamoxifen-inducible tyrosinase-promoter driven BrafV600E/Pten-/-/Cxcr2-/- and NRasQ61R/INK4a-/-/Cxcr2-/- melanoma models. In addition, the effects of a CXCR1/CXCR2 antagonist, SX-682, on melanoma tumorigenesis were evaluated in BrafV600E/Pten-/- and NRasQ61R/INK4a-/- mice and in melanoma cell lines. Potential mechanisms by which Cxcr2 affects melanoma tumorigenesis in these murine models were explored using RNAseq, mMCP-counter, ChIPseq, and qRT-PCR; flow cytometry, and reverse phosphoprotein analysis (RPPA). RESULTS Genetic loss of Cxcr2 or pharmacological inhibition of CXCR1/CXCR2 during melanoma tumor induction resulted in key changes in gene expression that reduced tumor incidence/growth and increased anti-tumor immunity. Interestingly, after Cxcr2 ablation, Tfcp2l1, a key tumor suppressive transcription factor, was the only gene significantly induced with a log2 fold-change greater than 2 in these three different melanoma models. CONCLUSIONS Here, we provide novel mechanistic insight revealing how loss of Cxcr2 expression/activity in melanoma tumor progenitor cells results in reduced tumor burden and creation of an anti-tumor immune microenvironment. This mechanism entails an increase in expression of the tumor suppressive transcription factor, Tfcp2l1, along with alteration in the expression of genes involved in growth regulation, tumor suppression, stemness, differentiation, and immune modulation. These gene expression changes are coincident with reduction in the activation of key growth regulatory pathways, including AKT and mTOR.

Abstract
Objective: To examine the outcomes of Tiantan first-aid protocol on critically ill patients with primary central nervous system lymphoma (PCNSL). Methods: The clinical data of 18 patients with PCNSL who were treated according to Tiantan first-aid protocol at Department of Neurosurgery,Beijing Tiantan Hospital, Capital Medical University from November 2019 to December 2021 were retrospectively analyzed. There were 9 males and 9 females, aged (56.9±11.1)years (range: 29 to 77 years). The median Karnofsky performance status(KPS) score at admission was 40 (range: 20 to 60). Three patients were mild coma, 3 were lethargy and 12 were conscious. The mean midline shift was 0.7 cm (range: 0 to 1.8 cm). After admission, all patients were treated according to the plan of rapid biopsy, rapid routine pathology and rapid salvage chemotherapy. The treatment procedures, clinical and radiographic outcomes, KPS score and adverse reactions of patients after chemotherapy were collected. Results: All of the 18 patients completed the first-aid treatment. The median duration from admission to the biopsy was 1 day (range: 0 to 5 days), from biopsy to routine pathological diagnosis was 1 day (range: 1 to 4 days) and from routine pathology to salvage chemotherapy was 1 day (range: 0 to 4 days). All the patients were pathologically confirmed with diffuse large B cell lymphoma, 1 patient was double-hit lymphoma. Seventeen patients underwent clinical remission and 1 died of cardiac dysfunction. The successful salvage rate was 17/18. Radiologically, complete remission was observed in 1 case, partial remission in 16 cases, and stable disease in 1 case. The median KPS score at discharge was 60 (range: 30 to 80). The mild gastrointestinal, hematological and hepatic adverse effects were observed after chemotherapy. Conclusion: Tiantan first-aid protocol is effective for critically ill patients with PCNSL, which has the merit to be popularly used and improved.

Abstract
Chlorfenapyr is a moderately dangerous insecticide widely used in agriculture. The mortality of acute poisoning patients is high, and there is no effective treatment. This paper retrospectively analyzes the clinical data of two cases of compound chlorfenapyr poisoning. The main symptoms of the patients were high fever, sweating, gradual coma, increased creatine kinase and myoglobin, with delayed poisoning symptoms. Despite comprehensive treatment, both patients died eventually. It indicated that chlorfenapyr was highly toxic and had a high mortality. In addition to routine symptomatic treatment for patients with acute poisoning, blood purification treatment should be actively carried out in the early stage.

Abstract
The effectiveness of different treatment processes on assimilable organic carbon (AOC) removal and bacterial diversity variations was evaluated in a water treatment plant. The van der Kooij technique was applied for AOC analysis and responses of bacterial communities were characterized by the metagenomics assay. Results show that the AOC concentrations were about 93, 148, 43, 51, 37, and 38 μg acetate-C/L in effluents of raw water basin, preozonation, rapid sand filtration (RSF), ozonation, biofiltration [biological activated carbon (BAC) filtration], and chlorination (clear water), respectively. Increased AOC concentrations were observed after preozonation, ozonation, and chlorination units due to the production of biodegradable organic matters after the oxidation processes. Results indicate that the oxidation processes were the main causes of AOC formation, which resulted in significant increases in AOC concentrations (18-59% increment). The AOC removal efficiencies were 47, 28, and 60% in the RSF, biofiltration, and the whole system, respectively. RSF and biofiltration were responsible for the AOC treatment and both processes played key roles in AOC removal. Thus, both RSF and biofiltration processes would contribute to AOC treatment after oxidation. Sediments from the raw water basin and filter samples from RSF and BAC units were collected and analyzed for bacterial communities. Results from scanning electron microscope analysis indicate that bacterial colonization was observed in filter materials. This indicates that the surfaces of the filter materials were beneficial to bacterial growth and AOC removal via the adsorption and biodegradation mechanisms. Next generation sequencing analyses demonstrate that water treatment processes resulted in the changes of bacterial diversity and community profiles in filters of RSF and BAC. According to the findings of bacterial composition and interactions, the dominant bacterial phyla were Proteobacteria (41% in RSF and 56% in BAC) followed by Planctomycetes and Acidobacteria in RSF and BAC systems, which might affect the AOC biodegradation efficiency. Results would be useful in developing AOC treatment and management processes in water treatment plants.

Abstract
Objective: To investigate the safety and short-term efficacy of domestic magnetic resonance-guided laser interstitial thermotherapy (MRgLITT) in the treatment of drug-resistant epilepsy. Methods: Patients with drug-resistant epilepsy treated with a domestic MRgLITT system in the Department of Neurosurgery, Xuanwu Hospital, Capital Medical University from October 2020 to April 2021 were prospectively enrolled. The damage volume ratio was assessed immediately after surgery, and perioperative complications were recorded and followed up. The clinical safety and short-term efficacy were evaluated using the Engel classification. Results: A total of 22 patients were included, including 12 males and 10 females, aged from 3 to 45 years old [(24±13) years]. There were 5 cases of medial temporal lobe epilepsy (MTLE), 3 cases of hypothalamic hamartoma (HH), 7 cases of focal cortical dysplasia (FCD), and 7 cases of other types, respectively. The mean operation time and blood loss was (173±49) min and (3.7±1.6) ml. The postoperative length of hospital stay was (5.5±1.8) days, and the average damage volume ratio was 92.6%. Among them, only 2 patients (FCD of the parietal lobe) showed transient contralateral limb weakness, without any serious complications such as symptomatic intracranial hemorrhage and cerebral infarction. The follow-up time was 14 to 168 days. There were 13 Engel class Ⅰ cases (59.1%), 2 Engel class Ⅱ cases (9.1%), 2 Engel class Ⅲ cases (9.1%) and 5 Engel class Ⅳ cases (22.7%), respectively. Short-term incident-free rates were MTLE 5/5and FCD4/7, respectively. Conclusion: Domestic MRgLITT system is stable, reliable and safe in the treatment of drug-refractory epilepsy, and has better short-term efficacy in MTLE and FCD patients.

Abstract
BACKGROUND Currently there is limited information to guide health professionals regarding the optimal time frame to initiate safe and effective oral feedings to preterm infants. The study aims to revise and validate a streamlined version of the Traditional Chinese-Preterm Oral Feeding Readiness Assessment Scale, the TC-POFRAS®, and evaluate its construct validity in the clinical decisions regarding feeding readiness of preterm infants. METHODS Eighty-one clinically stable preterm infants were assessed using the TC-POFRAS for oral feeding readiness. Item-total correlation analysis was used to check if any item was inconsistent with the averaged TC-POFRAS scores. Cronbach's α coefficient was used to evaluate the inter-item consistency. Exploratory factor analysis was used to determine the coherence of variables to reorganize assessment domains. The revised version of TC-POFRAS (TC-POFRAS®) was developed and a new cut-off score based on discriminant accuracy was established. RESULTS Based on the results from statistical analysis, five items ("lips posture," "tongue posture," "biting reflex," "gag reflex," and "tongue cupping") were deleted from the original TC-POFRAS to form the TC-POFRAS®. The TC-POFRAS®'s global accuracy was 92.1%. The cut-off value of 19 was the one that presented the most optimization of sensitivity based on specificity. The TC-POFRAS® was reconstructed into corrected gestational age and five behavioral domains. CONCLUSIONS The TC-POFRAS® is considered a valid, safe, and accurate objective instrument to assist health professionals to initiate oral feeding of preterm infants.

Abstract
BACKGROUND The ItchyQoL is an itch-specific patient-reported outcome measure used to assess quality of life in patients with chronic pruritus (CP). OBJECTIVES We aimed to assess and extend the psychometric properties of the ItchyQoL using classical test theory (CTT) and item response theory (IRT). METHODS Item characteristic curves were analysed to investigate whether the response categories were functioning optimally. Confirmatory factor analyses were carried out on the ItchyQoL prior to and after rescoring of the response categories. We conducted a Rasch analysis for the ItchyQoL with revised response options and assessed the mean fit residuals in addition to the assumptions of unidimensionality and local independence. RESULTS In total, 551 patients with CP from nine European countries completed the 22 items of the ItchyQoL. IRT analysis supported the revision of response options from five points to three. This revision was supported by excellent structural validity using CTT. The overall fit to the Rasch model was adequate. Unidimensionality was supported by the ItchyQoL overall scale and by the single subscales; however, local independence was violated in eight cases. CONCLUSIONS We suggest a revision of the response categories of the ItchyQoL from a 5-point to a 3-point scale. When this revision was applied, the ItchyQoL showed excellent structural validity according to CTT and IRT/Rasch. The calculation of an overall ItchyQoL sum score is allowed.

Abstract
Objective: To evaluate the airway and voice quality improvement in patients with bilateral vocal fold paralysis (BVFP) who underwent selective laryngeal reinnervation surgery. Methods: From January 2012 to December 2016, a retrospective study was conducted in 39 patients with BVFP who underwent selective laryngeal reinnervation surgery in Department of Otorhinolaryngology Head and Neck Surgery, the First Affiliated Hospital of Navy Medical University. All patients were examined by videostroboscopy, vocal function assessment, laryngeal electromyography and pulmonary function test before and after the surgery, and followed up for at least 2 years to evaluate the efficacy and safety of the surgery.Wilcoxon signed rank test was used to analyze the G score and VHI-10 score data. Paired t-test was used to analyze acoustic parameters, MPT values and pulmonary function parameters. Results: Postoperative infection and hemorrhage occurred in one patient separately.Videostroboscopic videos showed that at 4-8 months postoperatively, vocal folds in 35 patients achieved moderate or severe abduction during inspiration, 2 patients only achieved mild abduction, 2 patients showed no abduction,while all patients achieved adduction in bilateral vocal cords during phonation. The recovery rate of moderate-to-severe abduction was 89.7% (35/39), and these patients were decannulated successfully. At 12 months after operation, G score and VHI-10 score were significantly lower than those before operation (P<0.05), and the acoustic parameters jitter, shimmer, HNR and MPT were significantly improved (P<0.05). Most of the parameters of the pulmonary function test at 3 months postoperatively returned to the normal reference level, while the maximum inspiratory pressure (PImax) at 12 months after operation was still slightly lower than the normal level, but it was significantly improved compared with preoperative value (P<0.05). The EMG data at 12 months postoperatively showed full interference potentials in 37 patients in bilateral posterior cricoarytenoid muscles during inspiration, and full interference potentials in bilateralthyroarytenoid muscles during phonation. Obvious misdirected regeneration electric activitieswere found in two of them. Potentials in posterior cricoarytenoid muscle were weak in 2 cases with poor abduction. During long-term follow-up, only one case showed decreased abduction, but did not affect respiratory function. Conclusions: The selective laryngeal reinnervation procedure applied in the present study can restore physiological motion of vocal cords. The success rate was high, the curative effect was stable, and the complications were rare. It is worth of promotion.

Abstract
Objective: Comparison of the permeability between the rabbit cornea and sclera ex vivo by determining the concentration of gatifloxacin using LC-MS/MS method, which may provide the basis for a new route of drug administration. Methods: Experimental study. The permeability of the cornea and sclera in healthy male New Zealand rabbits was evaluated by using Franz diffusion pool. We chose both gatifloxacin ophthalmic solution and gel as the test drugs, and calculated the cumulative permeation amounts (Qn), apparent permeability coefficient(P(app)). Results: The linear range of gatifloxacin was 5-1 000 ng/ml. The intra-day and inter-day precision was 1.7% -2.8% and 1.0% - 2.3%. Q(n) and P(app) of gatifloxacin ophthalmic solution in cornea and sclera ex vivo were 177.57, 517.52 μg/cm(2) and 4.34, 12.51 cm/s respectively, whereas that of gatifloxacin ophthalmic gel were 151.87, 411.05 μg/cm(2) and 3.66, 9.21 cm/s. Conclusion: This validated method could be applied to determine the gatifloxacin. The cumulative permeation amounts and apparent permeability coefficient of sclera are significantly higher than that of cornea for both ophthalmic solution and gel, suggesting that the development of a new route of drug administration based on sclera may have potential advantage.

Abstract
The effectiveness of using gamma poly-glutamic acid (γ-PGA) as the primary carbon and nitrogen sources to bioremediate trichloroethene (TCE)-contaminated groundwater was studied in this pilot-scale study. γ-PGA (40 L) solution was injected into the aquifer via the injection well (IW) for substrate supplement. Groundwater samples were collected from monitor wells and IW and analyzed for TCE and its byproducts, geochemical indicators, dechlorinating bacteria, and microbial diversity periodically. Injected γ-PGA resulted in an increase in total organic carbon (TOC) (up to 9820 mg/L in IW), and the TOC biodegradation caused the formation of anaerobic conditions. Increased ammonia concentration (because of amine release from γ-PGA) resulted in the neutral condition in groundwater, which benefited the growth of Dehalococcoides. The negative zeta potential and micro-scale diameter of γ-PGA allowed its globule to distribute evenly within soil pores. Up to 93% of TCE removal was observed (TCE dropped from 0.14 to 0.01 mg/L) after 59 days of γ-PGA injection, and TCE dechlorination byproducts were also biodegraded subsequently. Next generation sequence (NGS) analyses were applied to determine the dominant bacterial communities. γ-PGA supplement developed reductive dechlorinating conditions and caused variations in microbial diversity and dominant bacterial species. The dominant four groups of bacterial communities including dechlorinating bacteria, vinyl chloride degrading bacteria, hydrogen producing bacteria, and carbon biodegrading bacteria.

Abstract
A total of 1 685 school-age children selected from Hangzhou received lung function testing to evaluate the short-term effects of air pollution on their lung function. The results showed that in every 10 μg/m(3) increase of average concentration of PM(2.5) and PM(10) on the day of the test and the day before the test,peak expiratory flow (PEF) decreased 0.039 (95%CI: 0.012-0.067) L/s and 0.031 (95% CI:0.011-0.051) L/s,respectively. When the average concentration of SO(2) increased 10 μg/m(3) on the day of test and the day prior to the test, PEF and 75% of the forced vital capacity that has not been exhaled (MEF(75)) decreased 0.437 (95%CI: 0.217-0.658) L/s and 0.396 (95%CI: 0.180-0.613) L/s. After being adjusted for NO(2),with every 10 μg/m(3) increase of average concentration of PM(2.5) and PM(10) on the day of the test and the day before the test,PEF and MEF(75) decreased 0.056 (95%CI: 0.028-0.085), 0.053(95%CI: 0.027-0.081) and 0.047 (95%CI: 0.026-0.068) L/s,0.044 (95%CI: 0.023-0.065) L/s on the day before the test, respectively. The results indicate that air pollution have short-term and lag effects on lung function of school-age children in Hangzhou.

Abstract
BACKGROUND Chronic pruritus (CP) is a frequently occurring symptom in inflammatory dermatoses, causing a high burden and limitations to health-related quality of life (HRQoL). OBJECTIVE The ItchyQoL was developed to assess the impairment to HRQoL in patients with CP. However, it has only been validated in English and German. Here, we report the validation in several languages across Europe. METHODS After professional translation, the versions of ItchyQoL were digitized for use as a tablet application. Validation was performed in clinics for dermatology in Austria, France, Germany, Italy, Poland, Russia, Spain, Switzerland and Turkey. RESULTS Five hundred and thirty-five patients with either contact dermatitis, chronic prurigo - nodular type, psoriasis vulgaris, lichen planus or mycosis fungoides/Sézary syndrome and with CP ≥ 3 on the numerical rating scale were included. ItchyQoL showed a high level of consistency (Cronbach's-α, all: 0.95) and test-retest reliability (intraclass correlation: 0.91). It strongly correlated with the Dermatology Life Quality Index (r = 0.72, P < 0.001) and moderately correlated with itch intensity scales in the study population (visual analogue scale r = 0.46; numerical rating scale r = 0.51; verbal rating scale r = 0.51, for all: P < 0.001). CONCLUSION ItchyQoL is now also validated in French, Italian, Polish, Russian, Spanish and Turkish and can be used in clinical trials in countries speaking these languages.

Abstract
Utilization of bacterial volatilization can be problematic to remediate mercury (Hg)-contaminated soils because most of the Hg in soils is bound to soil particles. The objective of this study was to develop a two-stage system (chemical extraction followed by microbial reduction) for Hg-contaminated soil remediation. The tasks were to (1) select the extraction reagents for Hg extraction, (2) assess the effects of extraction reagents on the growth of Hg-reducing bacterial strains, and (3) evaluate the effectiveness of Ca2+ and Mg2+ addition on merA gene (Hg reductase) induction. Bacterial inhibition was observed with the addition of 0.1 M ethylenediaminetetraacetic acid or citric acid. Up to 65% of Hg was biotransformed (Hg concentration = 69 mg/kg) from the soils after a 24 h extraction using 0.5 M ammonium thiosulfate. Ca2+ and Mg2+ were selected because they have the same electric charge as Hg and the studied groundwater contained high concentrations of Ca2+ and Mg2+. Results showed that the addition of 200 mg/L Ca2+ or 650 mg/L Mg2+ could reach effective merA induction. In the two-stage experiment, 120 mg/kg Hg-contaminated soils were extracted with 2 rounds of extraction processes for 10 h using 0.5 M ammonium thiosulfate. Approximately 77% of Hg was extracted from the soils after the first-step extraction process. Up to 81% of Hg2+ was transformed from the washing solution via the biotransformation processes with Enterobacter cloacae addition and Ca2+ and Mg2+ supplementation. The two-stage remedial system has the potential to be developed into a practical technology to remediate Hg-contaminated sites.

Abstract
Objective: To identify the cause on a foodborne breakout in a university of Hangzhou in 2014. Methods: Data on cases were gathered from the out-patient logs of the university affiliated or neighboring hospitals to describe the disease distribution and epidemiological curves. Case-control and field studies on hazard factors were conducted simultaneously. Results: The incubation period was 1.5-5.0 hours, of which the median was 3 during the outbreak. All the cases consumed food from a restaurant called Chen's Snacks nearby their university and suffered from the Staphylococcus aureus enterotoxin. Results from the Staphylococcus enterotoxin testing were positive in 3 stool and 6 food samples, out of the total 18 samples. Conclusion: This foodborne outbreak was caused through food poisoning by vermicelli which was contaminated with Staphylococcus aureus.

Abstract
Objective:To evaluate the feasibility and long-term outcome of radiofrequency coblation combined with silicon stent implantation in the treatment of recurrent laryngeal papilloma with extensive lesions. Method:From March 2009 to April 2016, a total of 13 patients (8 males, 5 females; aged 28-67 years) who suffered recurrent laryngeal papilloma were enrolled in this retrospective study. All the cases had undergone at least one operation at other hospitals before this hospitalization. The recurrence interval (RI) of these cases ranged from 2 to 6 months. Video-laryngoscopy or stroboscopy were preformed preoperatively and postoperatively, as well as vocal function assessment. These cases underwent radiofrequency coblationin combination of different stent implantation (member, 7 cases; tube, 4 cases; T-shaped tube, 2 cases) under general anesthesia. The follow-up was 12 to 76 months. Result:Laryngoscopy revealed that the lesions mainly located in the vocal folds, anterior commissure, ventricular band, posterior commissure, epiglottis and even in subglottic area. Varying extent of mucosal adhesion of anterior or/and posterior commissure were observed in all cases, and two cases suffered mild subglottic tracheal stenosis. Two to six weeks after surgery, the silicon stent were removed and no mucosal adhesion were found except for 2 cases who suffered mucosal adhesion of anterior commissure again. Compared to preoperative scores, VHI-10 and G scores showed the significant improvement of voice quality postoperatively in all cases. The recurrence of papilloma was observed in 3 cases during 1-year follow-up, and 4 cases during 2-year follow-up, no recurrence in 6 cases. These recurrence lesions mainly located in ventricular band, subglottic area and trachea. However, no recurrence occurred in these cases who received ablation again. No serious complications were observed in these cases. Conclusion:Radiofrequency ablation may be an effective approach in the treatment of recurrent laryngeal papilloma with extensive lesions. One-stage application of suitable silicon stents can effectively prevent the adhesion of the wound and the onset oflaryngo-tracheal stenosis, and improve the quality of voice.

Abstract
Intracranial hypertension leading to brain stem herniation is a major cause of death in fulminant hepatic failure (FHF). Mannitol, barbiturates, and hyperventilation have been used to treat brain swelling, but most patients are either refractory to medical management or cannot be treated because of concurrent medical problems or side effects. In this study, we examined whether allogeneic hepatocellular transplantation may prevent development of intracranial hypertension in pigs with experimentally induced liver failure. Of the two preparations tested—total hepatectomy (n = 47), and liver devascularization (n = 16)—only pigs with liver ischemia developed brain edema provided, however, that animals were maintained normothermic throughout the postoperative period. This model was then used in transplantation studies, in which six pigs received intrasplenic injection of allogeneic hepatocytes (2.5 × 109 cells/pig) and 3 days later acute liver failure was induced. In both models (anhepatic state, liver devascularization), pigs allowed to become hypothermic had significantly longer survival compared to those maintained normothermic. Normothermic pigs with liver ischemia had, at all time points studied, ICP greater than 20 mmHg. Pigs that received hepatocellular transplants had ICP below 15 mmHg until death; at the same time, cerebral perfusion pressure (CPP) in transplanted pigs was consistently higher than in controls (45 ± 11 mmHg vs. 16 ± 18 mmHg; p < 0.05). Spleens of transplanted pigs contained clusters of viable hepatocytes (hematoxylin-eosin, CAM 5.2). It was concluded that removal of the liver does not result in intracranial hypertension; hypothermia prolongs survival time in both anhepatic pigs and pigs with liver devascularization, and intrasplenic transplantation of allogeneic hepatocytes prevents development of intracranial hypertension in pigs with acute ischemic liver failure.

Abstract
To enhance the reductive dechlorination of 1,2-dichloroethane (DCA) in groundwater, substrate injection may be required. However, substrate biodegradation causes groundwater acidification and sulfide production, which inhibits the bacteria responsible for DCA dechlorination and results in an odor problem. In the microcosm study, the effectiveness of the addition of ferrous sulfate (FS), desulfurization slag (DS), and nanoscale zero-valent iron (nZVI) on acidification and sulfide control was studied during reductive dechlorination of DCA, and the emulsified substrate (ES) was used as the substrate. Up to 94% of the sulfide was removed with FS and DS addition (0.25 wt%) (initial DCA concentration = 13.5 mg/L). FS and DS amendments resulted in the formation of a metal sulfide, which reduced the hydrogen sulfide concentration as well as the subsequent odor problem. Approximately 96% of the DCA was degraded under reductive dechlorination with nZVI or DS addition using ES as the substrate. In microcosms with nZVI or DS addition, the sulfide concentration was reduced to less than 15 μg/L. Acidification can be controlled via hydroxide ions production after nZVI oxidation and reaction of free CaO (released from DS) with water, which enhanced DCA dechlorination. The quantitative polymerase chain reaction results confirmed that the microcosms with nZVI added had the highest Dehalococcoides population (up to 2.5 × 10(8) gene copies/g soil) due to effective acidification control. The α-elimination mechanism was the main abiotic process, and reductive dechlorination dominated by Dehalococcides was the biotic mechanism that resulted in DCA removal. More than 22 bacterial species were detected, and dechlorinating bacteria existed in soils under alkaline and acidic conditions.

Abstract
Objective:To investigate the application of the reconstruction methods for hypopharyngeal and cervical esophageal defects due to the resection of hypopharyngeal cancer and advanced laryngeal cancer between free fasciocutaneous flaps and free jejunium transfer.We compared the superiorities and inferiorities of these two reconstruction methods. Method:Retrospective review of the archives of 56 patients from 2000 to 2010 who underwent pharyngoesophageal reconstruction with free flaps (n=32) or free jejunal transfer(n=24),comparison of indications,complications, hospitalization duration, swallowing function recovery and postoperative survival time. Result:The overall 3 year survival rate of free flap group and free jejunal transfer group was 59.3%,55.7% respectively; the overall 5 year survival rate was 38.5%,37.1% respectively. The overall rate of complication rate was 18.8%, 16.7% respectively. The patients with free flaps had higher incidence rate of fistula and scarring in the donor site and lower incidence rate of hues and stricture than the ones with free jejunal transfers. The mean hospitalization duration was (15.00±7.06) days and(13.00±6.75) days. The mean time of first oral food intake was(13.00±5.83)days and (11.00±6.67) days. The differences between two groups had no statistical significance(P>0.05). Conclusion:Free flaps and free jejunium transfer are the two most common reconstruction methods for the hypopharyngeal and cervical esophageal defects. Each has its own advantages and disadvantages respectively. We should choose reconstruction method according to the site and extent of the hypopharyngeal and cervical esophageal defects, preoperative and postoperative radiotherapy requirement.

Abstract
Three-center two-electron bonds are important for understanding electron-deficient molecules. To examine such a molecule, we produced a diborane(5) anion with a single-bridged structure upon electron bombardment during matrix deposition of Ar containing a small proportion of diborane(6). The diborane(5) anion was destroyed upon photolysis at 180, 220, 385, and 450 nm, but not at 532 nm. Moreover, the possible formation of neutral diborane(5) was observed upon photolysis at 385 and 450 nm, whereas neutral diborane(3) was observed upon photolysis at 180 and 220 nm. The observed line wavenumbers, relative intensities, and isotopic ratios of the diborane(5) anion agreed satisfactorily with those predicted by density functional theory calculations at the B3LYP/aug-cc-pVTZ level of theory. Thus, this method produced the boron hydride anion of interest with few other fragments, which enabled us to clearly identify the IR spectrum of the diborane(5) anion.

Abstract
This article introduces the second revision of the Australian and New Zealand consensus guidelines for the use of antifungal agents in the haematology/oncology setting. The current update occurs within the context of a growing population at risk of invasive fungal disease, improved understanding of risk factors, availability of new diagnostic tests, a much-expanded evidence base and changing clinical paradigms. Here, we provide an overview of the history and purpose of the guidelines, including changes in scope since the last clinical update was published in 2008. The process for development, and for enabling review of draft recommendations by end-users and other relevant stakeholders, is described. The approach to assigning levels of evidence and grades of recommendation is also provided, along with a comparison to international grading systems.

Abstract
Pathogenic yeast forms are commonly associated with invasive fungal disease in the immunocompromised host, including patients with haematological malignancies and patients of haemopoietic stem cell transplants. Yeasts include the Candida spp., Cryptococcus spp., Pneumocystis jirovecii and some lesser-known pathogens. Candida species remain the most common cause of invasive yeast infections (and the most common human pathogenic fungi). These guidelines present evidence-based recommendations for the antifungal management of established, invasive yeast infections in adult and paediatric patients in the haematology/oncology setting. Consideration is also given to the critically ill patient in intensive care units, including the neonatal intensive care unit. Evidence for 'pre-emptive' or 'diagnostic-driven antifungal therapy' is also discussed. For the purposes of this paper, invasive yeast diseases are categorised under the headings of invasive candidiasis, cryptococcosis and uncommon yeast infections. Specific recommendations for the management of Pneumocystis jirovecii are presented in an accompanying article (see consensus guidelines by Cooley et al. appearing elsewhere in this supplement).

Abstract
This article reports the findings of a survey developed to assess the current use of antifungal prophylaxis among haematology and infectious disease clinicians across Australia and New Zealand, and their alignment with existing consensus guidelines for the use of antifungal agents in the haematology/oncology setting (published 2008). Surveyed clinicians largely followed the current recommendations for prophylaxis in the setting of induction chemotherapy for acute myeloid leukaemia, as well as autologous and low-risk allogeneic haemopoietic stem cell transplantation (HSCT). In keeping with guideline recommendations, posaconazole was the agent used by most centres for high-risk allogeneic HSCT. However, its routine continuation for 75-100 days post-transplantation without de-escalation suggested use beyond those indications described in the 2008 guidelines, namely pre-engraftment neutropenia and graft-versus-host disease. Variations in practice were observed in other settings, such as acute lymphoblastic leukaemia and myelodysplastic syndrome, reflecting the general lack of evidence for antifungal prophylaxis in these patient populations and changing perceptions of risk. With regard to the availability of testing in cases of suspected breakthrough IFD, 40% of centres did not have access to investigative bronchoscopy within 48 h of referral, and results of Aspergillus galactomannan (GM), fungal polymerase chain reaction and therapeutic drug monitoring (TDM) were not available within 48 h in 83%, 90% and 85% of centres respectively. The survey's findings will influence the recommendations provided in the updated 2014 consensus guidelines for the use of antifungal agents in the haematology/oncology setting.

Abstract
Pneumocystis jirovecii infection (PJP) is a common cause of pneumonia in patients with cancer-related immunosuppression. There are well-defined patients who are at risk of PJP due to the status of their underlying malignancy, treatment-related immunosuppression and/or concomitant use of corticosteroids. Prophylaxis is highly effective and should be given to all patients at moderate to high risk of PJP. Trimethoprim-sulfamethoxazole is the drug of choice for prophylaxis and treatment, although several alternative agents are available.

Abstract
Long-term culture and monitoring of individual multicellular spheroids and embryoid bodies (EBs) remains a challenge for in vitro cell propagation. Here, we used a continuous 3D projection printing approach - with an important modification of nonlinear exposure - to generate concave hydrogel microstructures that permit spheroid growth and long-term maintenance, without the need for spheroid transfer. Breast cancer spheroids grown to 10 d in the concave structures showed hypoxic cores and signs of necrosis using immunofluorescent and histochemical staining, key features of the tumor microenvironment in vivo. EBs consisting of induced pluripotent stem cells (iPSCs) grown on the hydrogels demonstrated narrow size distribution and undifferentiated markers at 3 d, followed by signs of differentiation by the presence of cavities and staining of the three germ layers at 10 d. These findings demonstrate a new method for long-term (e.g. beyond spheroid formation at day 2, and with media exchange) 3D cell culture that should be able to assist in cancer spheroid studies as well as embryogenesis and patient-derived disease modeling with iPSC EBs.

Abstract
A long-lasting emulsified colloidal substrate (LECS) was developed for continuous carbon and nanoscale zero-valent iron (nZVI) release to remediate trichloroethylene (TCE)-contaminated groundwater under reductive dechlorinating conditions. The developed LECS contained nZVI, vegetable oil, surfactants (Simple Green™ and lecithin), molasses, lactate, and minerals. An emulsification study was performed to evaluate the globule droplet size and stability of LECS. The results show that a stable oil-in-water emulsion with uniformly small droplets (0.7 μm) was produced, which could continuously release the primary substrates. The emulsified solution could serve as the dispensing agent, and nZVI particles (with diameter 100-200 nm) were distributed in the emulsion evenly without aggregation. Microcosm results showed that the LECS caused a rapid increase in the total organic carbon concentration (up to 488 mg/L), and reductive dechlorination of TCE was significantly enhanced. Up to 99% of TCE (with initial concentration of 7.4 mg/L) was removed after 130 days of operation. Acidification was prevented by the production of hydroxide ion by the oxidation of nZVI. The formation of iron sulfide reduced the odor from produced hydrogen sulfide. Microbial analyses reveal that dechlorinating bacteria existed in soils, which might contribute to TCE dechlorination.

Abstract
A 23-year-old woman who had experienced repeated stillbirths, was found to carry an additional segment on the long arm of the X chromosome. Array comparative genomic hybridization (aCGH) confirmed the origin of the 2 duplications (about 17.11 Mb). Thus, her karyotype was 46, X, dup (X) (q13.2-q21.1), dup(X) (q21.32-q22.1). We demonstrate that aCGH is a useful complementary tool to cytogenetic analysis for accurately determining banding. To our knowledge, this is the first case with normal apparently phenotype who inherited 2 duplications on Xq. Notably, after 2 stillbirths, she bore a healthy, normal female infant via natural pregnancy. Thus, a carrier of this karyotype can birth a phenotypically normal child.

Abstract
OBJECTIVE To investigate the predictors of use of anti-amoebiasis protective measures (AAPMs) among Taiwan immigrants returning to their country of origin, using the Health Belief Model (HBM) to guide the investigation. DESIGN Cross-sectional study. METHODS Between March and May 2011, all permanent immigrants originating from amoebiasis-endemic countries who received services at the immigrant service centres in Taipei or Tainan and who reported that they had returned to their country of origin within the past five years were enrolled in the study. A structured questionnaire containing questions on sociodemographic characteristics and items related to the constructs of the HBM was used as the data collection instrument. RESULTS Complete information was collected from 384 immigrants, with a response rate of 80% (384/480). The mean age of the subjects was 38.4 years (standard deviation 10.6 years). The majority (70%) of participants did not receive travel information through a pretravel consultation, and more than 17% reported that they did not use measures to prevent amoebiasis. Multiple regression analyses revealed that Chinese proficiency, pretravel consultation and lower barriers to using protective measures were significantly associated with the use of AAPMs during return trips to country of origin (R(2) = 0.45; F = 77.5; P < 0.001). CONCLUSION The HBM significantly predicted the use of AAPMs in this study. A high proportion of immigrants did not use appropriate AAPMs when they returned to their country of origin. Educational approaches should be targeted at immigrants originating from amoebiasis-endemic regions who return to their country of origin.

Abstract
Triple-negative breast cancer (TNBC) relapses more frequently than hormone receptor-positive subtypes and is often associated with poor outcomes. This retrospective study reviewed the pattern of distant metastasis with regard to survival in patients with TNBC. A total of 205 TNBC patients were analyzed. TNBC patients with lung metastases had the longest median post-metastatic OS (with 95% confidence interval) of 16.6 (10.3-22.9) months, followed by the bone, 16.3 (11.7-20.8) months, the liver, 8.9 (3.5-14.4) months, the pleura, 7.5 (2.8-12.3) months, and the brain, 4.3 (0.6-8.0) months. Kaplan-Meier plots indicated that TNBC patients with metastatic spread to brain, liver, and pleural had poorer post-metastatic OS rate than patients with lung metastases (p = 0.001, 0.004, and 0.029, respectively). Moreover, brain and liver metastases correlated significantly with poorer post-metastatic OS as compared to bone metastasis (p = 0.004 and 0.011, respectively). Route of first metastasis correlated significantly with survival of TNBC patients with brain metastases being the poorest survival indicator, followed by metastases to liver, pleura, bone, and lung.

Abstract
The 100-nm NiO-Ag composite films with Ag content of 0 to 24.4 at.% are deposited on glass substrates. It is found that an ultra high electric resistivity (rho) value is obtained and cannot be detected by four point probe measurement when the Ag content is less than 3.4 at.%. The rho value is reduced significantly to 29.0 Omega-cm as Ag content is increased to 4.2 at.%, and it decreases greatly to 0.009 Omega-cm as the content of Ag is further increased to 24.4 at.%. The NiO-Ag composite film with Ag content of 4.2 at.% shows p-type conduction. However, it becomes n-type when the Ag content increases to 9.3 at.%, which results from the Ag atoms segregated at grain boundary of NiO when the excess Ag atoms are added into NiO films. On the other hand, the transmittance of the NiO-Ag films drops continuously from 96.3% to 31.6% as the Ag content increases from 0 to 24.4%.

Abstract
CoPt/Ag films were prepared by magnetron sputtering on glass substrates and subsequent annealing. The dependence of degree of ordering and magnetic properties on Ag film thickness and annealing conditions were investigated. It was found that the Ag underlayer played a dominant role in inducing the (001) texture of the CoPt film after annealing. CoPt films with a thickness about 20 nm and Ag underlayers with a thickness about 70 nm are easy to obtain a large degree of ordering and a perpendicular magnetic anisotropy after annealing at 700 degrees C for 30 min. CoPt/Ag films with out-of-plane coercivity (Hc (perpendicular)) in the range of 13.5-14.0 kOe and a out-of-plane squareness (S(perpendicular)) of 0.97 were obtained after annealing at 700 degrees C for 30 min. Ag underlayer is beneficial to enhance the Hc(perpendicular)and S(perpendicular) of CoPt film significantly. The degree of ordering and perpendicular magnetic properties of the CoPt films which deposited on Ag underlayer are larger than those of the single layer CoPt films.

Abstract
In this study, the (GeSbSn)(100-x0Co(x) films (x = 0-13.3) were deposited on natural oxidized silicon wafer and glass substrate by dc magnetron co-sputtering of GeSbSn and Co targets. The ZnS-SiO2 films were used as protective layers. The thicknesses of the (GeSbSn)(100-x)Co(x) films and protective layer were 100 nm and 30 nm, respectively. We investigated the effects of Co addition on the thermal property, crystallization kinetics, and crystallization mechanism of the GeSbSn recording film. The crystallization temperatures of (GeSbSn)(100-x)Co(x) films were decreased with Co content. It was found that the activation energy of the (GeSbSn)(100-x)Co(x) films will decrease from 1.53 eV to 0.55 eV as Co content increased from 0 at.% to 13.3 at.%.

Abstract
The (In15Sb85)(100-x)Zn(x) films (x = 0 - 17.4) were deposited on nature oxidized Si wafer and glass substrate at room temperature by magnetron co-sputtering of Sb target and InZn composite target. The thermal property of the films was examined by a homemade reflectivity thermal analyzer. Microstructures of the films were analyzed by transmission electron microscope (TEM). We examined the effects of Zn addition on the thermal property, crystallization kinetics, and crystallization mechanism of the In15Sb85 recording film. As x = 0 - 17.4, thermal analysis shows that the (In15Sb85)(100-x)Zn(x) films have two phase transition temperature ranges which are 189 degrees C-215 degrees C and 300 degrees C-350 degrees C. It is found that the activation energy is increased with Zn content. This indicates that the thermal stability of amorphous state is improved by doping Zn. The optical contrasts of the films are all larger than 15%, as x = 0 - 6.2, indicating that the films have the potential in blue laser optical recording media application.
