In vivo study of chelating agent-modified nano zero-valent iron: Biodistribution and toxicity in mice.

In this study, the distribution and toxicity of nanoscale zero valent iron (nZVI) and nZVIs coated with citric acid and sodium tripolyphosphate (CA-nZVI and STPP-nZVI) in mice were investigated. nZVIs were primarily found in the livers and spleens, followed by the lungs, hearts, and kidneys. Histologic analysis revealed no significant histopathologic abnormalities or lesions in all organs except the liver at 14th d gavage. nZVIs did not have a noticeable impact on the body weight of the mice or the weight of their organs. Compared with the control group, there were no significant changes in hematology indexes in the nZVIs groups. However, the nZVIs groups exhibited varying levels of elevation in alanine aminotransferase, aspartate aminotransferase, and creatinine, suggesting liver and kidney inflammation in mice. The up-regulation of Nuclear Factor erythroid 2-Related Factor 2 and Heme oxygenase 1 in the nZVIs groups may be a response to nZVIs-induced oxidative stress. Immunohistochemical analysis confirmed the inflammatory response induced by the three nZVI groups. Chelating agents did not have a significant impact on the distribution or toxicity of nZVIs in mice. This study contributes to a comprehensive and detailed insight into nZVI toxicity in the environmental field.

Laparoscopic ureteroneocystostomy with bladder flap for benign ureteral stenosis: our initial experience.

To present our experience with laparoscopic ureteroneocystostomy with bladder flap (LUCBF) for treating benign ureteral stenosis and evaluate its feasibility and efficacy. The clinical data of 27 patients with benign ureteral stenosis who underwent LUCBF were retrospectively analyzed. After identification and excision of the ureteral stenosis segment, the healthy ureteral stump was dissected and incised longitudinally. A U-shaped or spiral bladder flap was harvested from the anterolateral bladder wall for ureteroplasty. All patients underwent LUCBF successfully, including 14 patients were combined with psoas hitch technique, between 90 and 220 min (median, 155 min). The median length of ureteral defect was 6 cm (range, 5-17 cm). The median blood loss was 40 ml (20-150 ml). The median indwelling time of double-J stent was 8 weeks (range, 4-8 weeks). Five patients (10.6%) suffered postoperative complications during the follow-up period (range, 12-48 months), including fever, hematuria, urinary tract infection and recurrent stenosis. The success rate was 96.3% (26/27). Patients with long ureter defects had longer operative time and more blood loss than short ureter defects. LUCBF was a safe and feasible technique for benign ureteral stenosis. Long ureter defect was related to longer operative time and more blood loss.

Erector spinae plane block versus caudal block for postoperative analgesia in pediatric patients undergoing inguinal hernia repair: a randomized controlled trial.

BACKGROUND: Erector spinae plane block is a promising strategy for pain management in some settings. However, the effectiveness of erector spinae plane block versus caudal block in pediatric inguinal hernia repair has yet to be formally investigated. METHODS: One hundred and two patients aged 2-5 years undergoing unilateral open inguinal hernia repair randomly received unilateral erector spinae plane block (0.2% ropivacaine 0.5 mL kg-1), caudal block (0.2% ropivacaine 1 mL kg-1), or no block. The primary outcome was time to the first rescue analgesia, defined as the interval from the end of surgery to the Face, Legs, Activity, Cry, and Consolability scale greater than three. Secondary outcomes included the number of patients requiring rescue analgesia, the area under the curve of pain scores over time, satisfaction of guardians, and adverse events. RESULTS: The median time to the first rescue analgesia was longer in the erector spinae plane block group than in the caudal block group [10.0 h (interquartile range, 6.6-24.0 h) vs. 5.0 h (interquartile range, 2.9-7.3 h); p < .001]. The Cox regression model demonstrated that the risk of postoperative rescue analgesia requirement was 0.38 in children receiving erector spinae plane block compared with caudal block (95% confidence interval 0.23-0.64; p < .001). Additionally, the area under the curve of the pain scores over time was lower in the erector spinae plane block group than in the caudal block group (44.3 [36.6-50.7] vs. 59.0 [47.1-64.5]; p < .001). CONCLUSIONS: Erector spinae plane block provided superior postoperative analgesia compared to caudal block in children undergoing inguinal hernia repair.Trial registration: Chinese Clinical Trial Registry; ChiCTR2100048303.

Erector spinae plane block (ESPB) is beneficial for postoperative analgesia in children undergoing inguinal hernia repair.Ultrasound-guided ESPB provided superior analgesia efficacy to caudal block in the pediatric population.ESPB is an attractive strategy for pain management after lower abdominal surgical procedures.

Case Report: A MiT family translocation renal cell carcinoma in the renal pelvis, calyces and upper ureter misdiagnosed as upper tract urothelial carcinoma.

Background: Upper tract urothelial carcinoma (UTUC) is the most common urothelial malignancy in the renal pelvis or ureter. Renal pelvic carcinoma accounts for 90% of all tumours in the renal pelvis, so the mass in the renal pelvis is usually considered a UTUC. Renal cell carcinoma (RCC) in the renal pelvis, calyces and upper ureter is extremely rare, especially MiT family translocation RCC, which makes this case even more uncommon. Case presentation: We report the case of a 54-year-old man had intermittent painless gross haematuria with occasional blood clots and urodynia for 2 years. Contrast-enhanced computed tomography (CT) and magnetic resonance imaging (MRI) scan showed an enlarged left kidney, and a soft tissue mass was seen in the renal pelvis, calyces and upper ureter. The patient's urine-based cytology was positive three times. Due to the severity of the upper ureteral lumen stenosis, we did not perform pathological biopsy during ureteroscopy. In the current case, clinical symptoms, imaging examinations, urine-based cytology, and ureteroscopy were combined to obtain a preoperative diagnosis of UTUC. Therefore, robot-assisted laparoscopic left radical nephroureterectomy and retroperitoneal lymphadenectomy were performed. Unexpectedly, the patient was pathologically diagnosed with MiT family translocation RCC after surgery. The surgery was uneventful. There was no intestinal tube injury or other complications perioperatively. The postoperative follow-up was satisfactory. Conclusion: MiT family translocation RCC in the renal pelvis, calyces and upper ureter is extremely rare, and can be easily confused with UTUC, resulting in the expansion of surgical scope. Preoperative ureteroscopy and biopsy or tumour punch biopsy should be used to obtain accurate pathology as far as possible, and the selection of correct surgical method is conducive to a good prognosis for patients.

Fluoxetine alleviates postoperative cognitive dysfunction by attenuating TLR4/MyD88/NF-κB signaling pathway activation in aged mice.

OBJECTIVE AND DESIGN: Postoperative cognitive dysfunction (POCD) is a common complication following surgery among elderly patients. Emerging evidence demonstrates that neuroinflammation plays a pivotal role in the pathogenesis of POCD. This study tested the hypothesis that fluoxetine can protect against POCD by suppressing hippocampal neuroinflammation through attenuating TLR4/MyD88/NF-κB signaling pathway activation. SUBJECTS: Aged C57BL/6 J male mice (18 months old) were studied. TREATMENT: Aged mice were intraperitoneally injected with fluoxetine (10 mg/kg) or saline for seven days before splenectomy. In addition, aged mice received an intracerebroventricular injection of a TLR4 agonist or saline seven days before splenectomy in the rescue experiment. METHODS: On postoperative days 1, 3, and 7, we assessed hippocampus-dependent memory, microglial activation status, proinflammatory cytokine levels, protein levels related to the TLR4/MyD88/NF-κB signaling pathway, and hippocampal neural apoptosis in our aged mouse model. RESULTS: Splenectomy induced a decline in spatial cognition, paralleled by parameters indicating exacerbation of hippocampal neuroinflammation. Fluoxetine pretreatment partially restored the deteriorated cognitive function, downregulated proinflammatory cytokine levels, restrained microglial activation, alleviated neural apoptosis, and suppressed the increase in TLR4, MyD88, and p-NF-κB p65 in microglia. Intracerebroventricular injection of LPS (1 µg, 0.5 µg/µL) before surgery weakened the effect of fluoxetine. CONCLUSION: Fluoxetine pretreatment suppressed hippocampal neuroinflammation and mitigated POCD by inhibiting microglial TLR4/MyD88/NF-κB pathway activation in aged mice.

Design of Multi-DC Overdriving Waveform of Electrowetting Displays for Gray Scale Consistency.

Gray scale consistency in pixels was extremely important for electrowetting displays (EWDs). However, traditional electrowetting display driving waveforms could not obtain a pixel aperture ratio consistency, which led to the occurrence of gray inconsistency even if it was the same driving waveform. In addition, the oil backflow caused by charge trapping could not be sustained. Therefore, a multi-direct current (DC) overdriving waveform for gray scale consistency was proposed in this paper, which could effectively improve the performance of EWDs. The driving waveform was divided into a start-up driving phase and a stable driving phase. The stable driving phase was composed of a square wave with a duty cycle of 79% and a frequency of 43 Hz. Subsequently, an overdriving pulse was also introduced in the stable driving phase. The multi-DC driving waveform for gray scale consistency was applied to a thin film transistor-electrowetting display (TFT-EWD). The average difference between increasing driving voltage and decreasing driving voltage was only 2.79%. The proposed driving waveform has an aperture ratio of 3.7 times at low voltages compared to DC driving.

Design, Fabrication and Measurement of Full-Color Reflective Electrowetting Displays.

We designed, fabricated and measured full-color, reflective electrowetting displays (EWDs). The display system is composed of three-layer cyan, magenta and yellow EWD elements fabricated with standard photolithographic techniques. The EWDs were driven successfully by the proposed control system and the measurement results show that the electro-optical performance was improved. The aperture ratio of the EWD element can be tuned from 0 to ∼80% as the applied voltage is changed from 0 to 30 V. The response time and the color gamut were measured to be ∼18 ms and ∼58% NTSC, respectively. This paper makes it possible for large numbers of reflective full-color EWDs to be fabricated directly, with advantages of saving power significantly by 85% and no eye irritation compared with LED displays.

Validation of the translated version of the EVAN-G scale in a Chinese-speaking population.

BACKGROUND: This study aimed to translate the French version of a perioperative satisfaction questionnaire (EVAN-G) scale, a validated questionnaire for assessing perioperative patient satisfaction, into a Chinese version and validate it in Chinese-speaking patients. METHODS: We developed the Chinese version of the EVAN-G (EVAN-GC) scale based on the original French version of the EVAN-G. The EVAN-GC scale, the Short version of the Spielberger State-Trait Anxiety Inventory (S-STAI), and the McGill pain questionnaire (MGPQ) were administered on the WeChat mini program. We invited patients to complete these questionnaires within 4 to 24 h after surgery. The psychometric validation of the EVAN-GC scale included validity, reliability, and acceptability. RESULTS: Among 220 patients, 217 (98.6%) completed the EVAN-GC scale after surgery. The item-internal consistency revealed good construct validity. Compared with the total scores of the S-STAI and MGPQ, the EVAN-GC scale showed excellent convergent validity (ρ = - 0.32, P < 0.001; ρ = - 0.29, P < 0.001). The EVAN-GC scale could differentiate between groups, which showed good discriminate validity. The Cronbach's alpha coefficient (0.85) of the translated scale demonstrated satisfactory internal consistency reliability, and a 36-patient subsample retest evidenced good test-retest reliability (ρ = 0.82, P < 0.001). In addition, the median [interquartile range] time of completing the EVAN-GC scale was 3.7 [2.9-4.9] min. CONCLUSIONS: The EVAN-GC scale has good psychometric properties similar to those of the original French version. The EVAN-GC scale is a valid and reliable measurement to assess patient satisfaction in Chinese-speaking patients. TRIAL REGISTRATION: The Chinese Clinical Trial Registry, ChiCTR2100049555.

Dynamic Adaptive Display System for Electrowetting Displays Based on Alternating Current and Direct Current.

As a representative of the new reflective display technology, electrowetting display (EWD) technology can be used as a video playback display device due to its fast response characteristics. Direct current (DC) driving brings excellent reflectivity, but static images cannot be displayed continually due to charge trapping, and it can cause afterimages when playing a dynamic video due to contact angle hysteresis. Alternating current (AC) driving brings a good dynamic video refresh ability to EWDs, but that can cause flickers. In this paper, a dynamic adaptive display model based on thin film transistor-electrowetting display (TFT-EWD) was proposed. According to the displayed image content, the TFT-EWD display driver was dynamically adjusted by AC and DC driving models. A DC hybrid driving model was suitable for static image display, which could effectively suppress oil backflow and achieve static image display while ensuring high reflectivity. A source data non-polarized model (SNPM) is an AC driving model which was suitable for dynamic video display and was proposed at the same time. Compared with DC driving, it could obtain smooth display performance with a loss of about 10 absorbance units (A.U.) of reflective luminance, which could solve the flicker problem. With the DC hybrid driving model, the ability to continuously display static images could be obtained with a loss of 2 (A.U.) of luminance. Under the AC driving in SNPM, the reflected luminance was as high as 67 A.U., which was 8 A.U. higher than the source data polarized model (SPM), and it was closer to the reflected luminance under DC driving.

Discharge readiness after remimazolam versus propofol for colonoscopy: A randomised, double-blind trial.

BACKGROUND: Remimazolam is an ultrashort-acting benzodiazepine that is potentially a practical option for procedural sedation in colonoscopy. OBJECTIVE: To test the hypothesis that remimazolam could provide a noninferior discharge time to propofol for ambulatory colonoscopy. DESIGN: A prospective, randomised, double-blind, noninferiority clinical trial. SETTING: Ambulatory endoscopy centre. PATIENTS: A total of 132 adult participants undergoing ambulatory colonoscopy were enrolled. INTERVENTIONS: Participants were randomly assigned in a 1 : 1 ratio to receive propofol or remimazolam for sedation. MAIN OUTCOME MEASURES: The primary outcome was discharge time after a colonoscopy, assessed using the Modified Postanaesthetic Discharge Scoring System scale. Secondary outcomes included induction time, emergence time, the extent of recovery upon arrival in the postanaethesia care unit, fatigue, endoscopist and patient satisfaction and adverse events. RESULTS: The median discharge time was 24 min in the remimazolam group versus 21 min in the propofol group, with a difference of 2 min [95% confidence interval (CI), 0 to 4 min], meeting the criteria for noninferiority. Injection pain occurred in 11 of 66 (17%) participants receiving remimazolam versus 32 of 66 (49%) participants receiving propofol ( P  < 0.001); hypotension occurrence was 20% versus 47%, ( P  < 0.001), respectively, and bradycardia 6% versus 20%, ( P  = 0.019), respectively. Compared with propofol, the patient satisfaction score was higher in the remimazolam group ( P  < 0.001). CONCLUSION: For sedation in ambulatory colonoscopy, compared with propofol, remimazolam provides a noninferior discharge time. Furthermore, remimazolam is associated with less injection pain, lower risks of hypotension and bradycardia, and improved patient satisfaction.

Red Display for Three-Color Electrophoretic Displays with High Saturation via a Separation Stage between Black and Red Particles.

A three-color electrophoretic display (EPD) can solve the defect of an insufficient color display of black/white EPDs, but it is difficult to achieve a high red saturation due to the same driving polarity between black and red electrophoretic particles. In this work, a separation stage was proposed in the driving process to increase the red saturation in three-color EPDs. Firstly, red particles' motion was analyzed by the electrophoretic theory and Stokes' theorem to optimize driving parameters. Secondly, the activity of black particles was analyzed by testing different driving process parameters, and an optimal activation parameter for red particles was obtained. Next, the separation stage parameters were analyzed to reduce the mixing degree of black and red electrophoretic particles. Experimental results showed that the red and black electrophoretic particles could be effectively separated. Compared with an existing driving method, the red saturation was increased by 23.4%.

Ultrasound-Guided Thoracic Paravertebral Block Enhances the Quality of Recovery After Modified Radical Mastectomy: A Randomized Controlled Trial.

PURPOSE: Ultrasound-guided thoracic paravertebral block (TPVB) has become increasingly popular for postoperative analgesia after breast surgery. We designed this prospective, randomized, double-blind, placebo-controlled trial to test the hypothesis that TPVB is superior to placebo in improving the patient quality of recovery following modified radical mastectomy. PATIENTS AND METHODS: Sixty-eight female patients undergoing elective unilateral modified radical mastectomy were enrolled. Patients were randomized to receive preoperative ultrasound-guided TPVB with 0.5% ropivacaine (TPVB group, n=34) or 0.9% saline (Control group, n=34). The primary outcome was quality of recovery, measured 24 h after surgery using the 40-item Quality of recovery questionnaire (QoR-40). Secondary outcomes were the area under the curve of the visual analog scale pain scores over 24 h, postoperative 24-h morphine consumption, time to first rescue analgesia, length of post-anesthesia care unit stay, postoperative nausea and vomiting, and patient satisfaction. RESULTS: The global QoR-40 score 24 h postoperatively (median [interquartile range]) was 173 [170-177] in the TPVB group and 161 [160-164] in the control group (P<0.001), respectively, with a median difference (95% confidence interval) of 11 (9-14). Compared with the control group, preoperative TPVB decreased the area under the curve of the visual analog scale pain scores over 24 h, reduced postoperative 24-h morphine consumption, prolonged the time to first rescue analgesia, shortened the length of post-anesthesia care unit stay, lessened postoperative nausea and vomiting, and improved the patient satisfaction. CONCLUSION: A single preoperative injection of TPVB with ropivacaine enhances the quality of recovery and postoperative analgesia in patients following modified radical mastectomy.

A Separated Reset Waveform Design for Suppressing Oil Backflow in Active Matrix Electrowetting Displays.

The electrowetting display (EWD) is a kind of reflective paper-like display. Flicker and grayscale distortion are caused by oil backflow, which is one of the important factors restricting the wide application of EWDs. The charge embedding caused by the electric field force in the dielectric layer is the cause of oil backflow. To suppress oil backflow, a separated reset waveform based on the study of oil movement is proposed in this paper. The driving waveform is divided into two parts: a reset waveform and a grayscale waveform. The reset waveform generated by a reset circuit can be used to output various voltages. The grayscale waveform is set as a traditional PWM waveform. The reset waveform is composed of a charge-releasing stage and oil-moving back stage. Two phases are contained in the charge releasing stage. The overdriving voltage is used during the first phase to reverse the voltage of all pixels. The trapped charges can then be released from the dielectric layer during the second phase. A higher voltage is used during the oil-moving back stage to drive the oil faster in the pixel. By comparing the experimental data, the oil backflow time is extended 761 times by the reset waveform. The four grayscales can be maintained by the reset waveform after driving for 300 s.

Progress in Advanced Properties of Electrowetting Displays.

Electrowetting display (EWD) has promising prospects in the electronic paper industry due to it having superior characteristics, such as the ability to provide a comfortable reading experience and quick response. However, in real applications, there are also problems related to dielectric deterioration, excess power consumption, optical instability and narrow color gamut etc. This paper reviewed the existing challenges and recent progress made in terms of improving the optical performance and reliability of EWD. First, the principle of electrowetting applied in small and confined configurations is introduced and the cause of the failure of the dielectric layer is analyzed. Then, the function of the pixel structures is described to avoid display defects. Next, electric signal modulations are compared in terms of achieving good image quality and optical stability. Lastly, the methods are presented for color panel realization. It was concluded that multi-layer dielectrics, three-dimensional pixel structures, proper electric frequency-and-amplitude modulation and an RGB color panel are expected to resolve the current limitations and contribute to designing advanced reflective displays.

Suprapubic-assisted laparoendoscopic single-site surgery versus standard laparoscopic nephrectomy: A propensity score-based analysis.

OBJECTIVES: To compare suprapubic-assisted laparoendoscopic single-site surgery nephrectomy with standard laparoscopic nephrectomy. METHODS: A retrospective case-control study comparing three surgeons' experience with 122 suprapubic-assisted laparoendoscopic single-site surgery nephrectomy and 107 standard laparoscopic nephrectomy was carried out. Operative time, estimated blood loss, intraoperative complications, intraoperative conversion, postoperative bowel recovery, postoperative analgesics, postoperative visual analog pain scale score, postoperative length of stay, days before going back to work, postoperative complications and Patient Scar Assessment Questionnaire were compared after propensity score matching. RESULTS: A total of 97 matched pairs were obtained after propensity score matching. There were no statistically significant differences between the suprapubic-assisted laparoendoscopic single-site surgery nephrectomy and standard laparoscopic nephrectomy groups with respect to operative time, estimated blood loss, intraoperative complications, intraoperative conversion, postoperative bowel recovery, length of stay and postoperative complications. Suprapubic-assisted laparoendoscopic single-site surgery nephrectomy group had decreased postoperative analgesics (20.9 vs 23.5, P = 0.04), visual analog pain scale score at 24 h (4.28 vs 5.28, P = 0.000), visual analog pain scale score at discharge (1.01 vs 1.47, P = 0.000), days before going back to work (28.4 vs 31.9, P = 0.000) and Patient Scar Assessment Questionnaire score (34.0 vs 42.0, P = 0.000), compared with the standard laparoscopic nephrectomy group. CONCLUSIONS: Suprapubic-assisted laparoendoscopic single-site surgery nephrectomy and standard laparoscopic nephrectomy are equivalent in terms of the safety and efficacy. However, suprapubic-assisted laparoendoscopic single-site surgery nephrectomy confers less postoperative pain, fewer days before going back to work and better cosmetic result when compared with standard laparoscopic nephrectomy.

Driving Waveform Design of Electrophoretic Display Based on Optimized Particle Activation for a Rapid Response Speed.

Electrophoretic displays (EPDs) have excellent paper-like display features, but their response speed is as long as hundreds of milliseconds. This is particularly important when optimizing the driving waveform for improving the response speed. Hence, a driving waveform design based on the optimization of particle activation was proposed by analyzing the electrophoresis performance of particles in EPD pixels. The particle activation in the driving waveform was divided into two phases: the improving particle activity phase and the uniform reference grayscale phase. First, according to the motion characteristics of particles in improving the particle activity phase, the real-time EPD brightness value can be obtained by an optical testing device. Secondly, the derivative of the EPD brightness curve was used to obtain the inflection point, and the inflection point was used as the duration of improving particle activity phase. Thirdly, the brightness curve of the uniform reference grayscale phase was studied to set the driving duration for obtaining a white reference grayscale. Finally, a set of four-level grayscale driving waveform was designed and validated in a commercial E-ink EPD. The experimental results showed that the proposed driving waveform can cause a reduction by 180 ms in improving particle activity phase and 120 ms in uniform reference grayscale phase effectively, and a unified reference grayscale can be achieved in uniform reference grayscale phase at the same time.

Driving Waveform Design with Rising Gradient and Sawtooth Wave of Electrowetting Displays for Ultra-Low Power Consumption.

As a kind of paper-like display technology, power consumption is a very important index for electrowetting displays (EWDs). In this paper, the influence of driving waveforms on power consumption of the EWDs is analyzed, and a driving waveform with rising gradient and sawtooth wave is designed to reduce the power consumption. There are three stages in the proposed driving waveform. In the initial stage, the driving voltage is raised linearly from the threshold to the maximum value to reduce the invalid power consumption. At the same time, the oil breakup can be prohibited. And then, a section of sawtooth wave is added for suppressing oil backflow. Finally, there is a section of resetting wave to eliminate the influence of charge leakage. Experimental results show that the power consumption of the ultra-low power driving waveform is 1.85 mW, which is about 38.13% lower than that of the conventional used square wave (2.99 mW), when the aperture ratio is 65%.

A Driving System for Fast and Precise Gray-Scale Response Based on Amplitude-Frequency Mixed Modulation in TFT Electrowetting Displays.

The gray-scale display which is driven by PWM (pulse width modulation) in TFT (thin film transistor) electrowetting displays (EWDs) has some shortcomings, such as large amplitude of oil oscillation in pixels and slow response speed for displaying gray scale. In this paper, an amplitude-frequency mixed modulation driving system is proposed to improve the response speed of driving gray scale and enhance the oil stability when the gray scale is displayed. In the initial stage of the driving process, the oil is driven by a high voltage to close to the target luminance, and the driving voltage is then decreased to stabilize the oil. The electrowetting hysteresis curve was used to calculate the relation model between the driving voltage and the luminance of the pixel in the system, and the driving voltage value of the pixel at each driving stage was then set to make the oil precisely and rapidly stabilize at the target luminance value. In the output driving platform, the amplitude-frequency mixed modulation is realized based on the source IC, which was used to realize digital-to-analog conversion. An 8 inch EWD was tested using an Admesy colorimeter, and the experimental results show that the pixel response time is reduced by 70% and the gray-scale oscillation is reduced by 80%.

Effects of Phthalate Esters on Ipomoea aquatica Forsk. Seedlings and the Soil Microbial Community Structure under Different Soil Conditions.

Phthalate acid esters (PAEs) are the most frequently utilized synthetic chemical compounds worldwide. They are typical emergent contaminants and are currently attracting considerable concern due to their risks to plants, animals, and public health. Determining the vital environmental factors that affect the toxicity of target pollutants in soil is important for vegetable production and the maintenance and control of soil productivity. We investigated the influence of di-n-butyl phthalate (DBP) and bis(2-ethylhexyl) phthalate (DEHP) under different soil conditions on physiological changes in water spinach (Ipomoea aquatic Forsk.) seedlings and the rhizosphere soil microbial community. Supported by our former experiments in which we determined the representative concentrations that caused the most pronounced toxic effects, three experimental concentrations were studied including control soils without PAEs and spiked soils with either 20 mg DBP or DEHP kg-1 soil. The soil at all the three PAE concentrations was then adjusted to test two soil pH values, three levels of soil organic matter (SOM) content, and three levels of soil moisture content; thus, we completed 12 treatments or conditions simulating different soil environment conditions in greenhouses. After 30 days of cultivation, we analyzed the toxicity effects of two target PAEs on plant growth and physiological factors, and on soil microbial community characteristics. The toxicity of soil DBP and DEHP to the physiology of water spinach was found to be most affected by the soil pH value, then by SOM content, and least of all by soil moisture. The results of the 454 high-throughput sequencing analysis of the soil microbial community indicated that the toxicity of target PAEs to soil microorganisms was most affected by SOM content and then by soil moisture, and no clear relationship was found with soil pH. Under different soil conditions, declines in leaf biomass, chlorophyll a content, and carotenoid content-as well as increases in free amino acid (FAA) content, superoxide anion free radical activity, and hydroxyl radical activity-occurred in response to DBP or DEHP. Heavy use of chemical fertilizer, organic fertilizer, and high humidity led to the special environmental conditions of greenhouse soil, constituting the main conditions considered in this study. The results indicate that under the special highly intensive production systems of greenhouses, soil conditions may directly influence the effects of pollutant phytotoxicity and may thus endanger the yield, nutrient content, and food safety of vegetables. The combined studies of the impacts on plants and rhizosphere microorganisms give a more detailed picture of the toxic effects of the pollutants under different soil conditions.
