Abstract
Salt stress is one of the most serious abiotic stresses leading to reduced agricultural productivity. Polysaccharides from seaweed have been used as biostimulants to promote crop growth and improve plant resistance to abiotic stress. In this study, PGPR strain Burkholderia sp. BK01 was isolated from the rhizosphere of wheat, and it was characterized for phosphorus (Pi) dissolution, indole-3-acetic acid (IAA) production, ammonia (NH3) and exopolysaccharides (EPS). In particular, strain BK01 can efficiently produce extracellular polysaccharide with a yield of 12.86 g/L, using sorbitol as carbon source. BK01 EPS was identified as an heteropolysaccharide with Mw 3.559 × 106 Da, composed of (D)-galactose (75.3%), (D)-glucose (5.5%), (L)-rhamnose (5.5%), (D)-galactouronic acid (4.9%) and (D)-glucuronic acid (8.8%). The present work aims to highlight the effect of the BK01 EPS on growth and biochemical changes in Arabidopsis thaliana under salt stress (100 mM). The purified BK01 EPS at a concentration of 100 mg/L efficiently promoted the growth of plants in pot assays, improved the chlorophyll content, enhanced the activities of SOD, POD and CAT, and decreased the content of MDA. This results suggested that the polysaccharides produced by PGPR strain Burkholderia sp. BK01 can be used as biostimulants to promote plant growth and improve plant resistance to salt stress.

Abstract
The characterization and flocculation mechanism of a biopolymer flocculant produced by Sphingomonas sp. HL-1, were investigated. The bio-flocculant HL1 was identified as an acidic polysaccharide, mainly composed of glucose, and also contained a small amount of mannose, galacturonic acid and guluronic acid. The flocculating activity of the purified HL1 polysaccharide could be activated by trivalent cations, and its flocculation mechanism was mainly charge neutralization and bridging. The working concentration of fermentation broth HL1 in a kaolin suspension was only 1/10,000 (v/v), in which the polysaccharide concentration was about 2 mg/L. The bio-flocculant HL1 maintained high efficiency at a wide range of pH (pH 3-10). It also exhibited good flocculating activity at a temperature range of 20-40 °C; it could even tolerate high salinity and kept activity at a mineralization degree of 50,000 mg/L. Therefore, the bio-flocculant HL1 has a good application prospect in the treatment of wastewater over a broad pH range and in high salinity.

Abstract
Rhamnolipids have significant emulsifying activity and the potential to become a component of pesticide emulsifier. Rhamnolipids are usually composed of two main components: mono-rhamnolipids (Rha-C10-C10) and di-rhamnolipids (Rha2-C10-C10). The proportion of di-rhamnolipids in the products ranged between 15% and 90%, affected by the production strains and fermentation process. In this paper, three kinds of rhamnolipid products containing di-rhamnolipids proportions, of 25.45, 46.46 and 89.52%, were used to test their emulsifying ability toward three conventional solvents used in pesticide (S-200, xylene, cyclohexanone) and antifungal activities against five strains of plant pathogenic fungi (Phytophthora capsici, Phytophthora parasitica var.nicotianae, Colletotrichum destructivum, Colletotrichum sublineolum, Fusarium oxysporum). The results indicated that although the CMC of the three rhamnolipids were significantly different, their emulsification properties had no remarkable differences, at a concentration of 10 g/L. However, their antifungal activities were significantly different: the more di-rhamnolipids, the stronger the antifungal activity. This work helps to promote the application of rhamnolipids as pesticides adjuvants.

Abstract
OBJECTIVE To investigate the prevalence of Schistosoma japonicum infection in wild mice in Shitai County, Anhui Province, so as to provide insights into precise control of the source of S. japonicum infections. METHODS Wild mice were captured using the trapping method for three successive nights at snail-infested settings from Jitan Village of Jitan Township, and Shiquan Village and Xibai Village of Dingxiang Township, Shitai County, Anhui Province in June and October, 2018. All trapped wild mice were sacrificed and liver and mesenteric vein specimens were collected for detection of S. japonicum eggs using microscopy, while the fecal samples in mouse intestines were collected for identification of S. japonicum infections using Kato-Katz technique. In addition, the population density of trapped wild mice was estimated and the prevalence of S. japonicum infection was calculated in trapped wild mice. RESULTS A total of 376 wild mice were trapped from three villages in Shitai County. The population density of trapped wild mice was 9.1% (376/4 124), and the prevalence of S. japonicum infection was 24.2% (91/376) in trapped wild mice. The highest prevalence of S. japonicum infection was detected in Shiquan Village of Dingxiang Township (30.1%), and the lowest prevalence was seen in Xibai Village of Dingxiang Township; however, there was no significant difference in the prevalence of S. japonicum infection in trapped wild mice among three villages (χ2= 4.111, P > 0.05). In addition, there was no significant difference in the prevalence of S. japonicum infection in wild mice captured between on June (26.8%, 34/127) and October (22.9%, 57/249) (χ2 = 0.690, P = 0.406). The trapped wild mice included 6 species, including Rattus norvegicus, Niviventer niviventer, R. losea, Apodemus agrarius, Mus musculus and N. coning, and the two highest prevalence of S. japonicum infection was detected in R. losea (34.9%, 22/63) and R. norvegicus (31.2%, 44/141). CONCLUSIONS The prevalence of S. japonicum infections is high in wild mice in Shitai County, and there is a natural focus of schistosomiasis transmission in Shitai County.

Abstract
BACKGROUND Although the flow diverter has advantages in the treatment of intracranial aneurysms, pooled studies that directly compare it with conventional endovascular treatments are rare. PURPOSE Our aim was to compare the safety and efficacy of flow-diverter and conventional endovascular treatments in intracranial aneurysms. DATA SOURCES We performed a comprehensive search of the literature using PubMed, EMBASE, and the Cochrane Database. STUDY SELECTION We included only studies that directly compared the angiographic and clinical outcomes of flow-diverter and conventional endovascular treatments. DATA ANALYSIS Random effects or fixed effects meta-analysis was used to pool the cumulative rate of short- and long-term angiographic and clinical outcomes. DATA SYNTHESIS Eighteen studies with 1001 patients with flow diverters and 1133 patients with conventional endovascular treatments were included; 1015 and 1201 aneurysm procedures were performed, respectively. The flow-diverter group had aneurysms of a larger size (standard mean difference, 0.22; 95% CI, 0.03-0.41; P = .026). There was a higher risk of complications in the flow-diverter group compared with the conventional endovascular group (OR, 1.4; 95% CI, 1.01-1.96; P = .045) during procedures. The follow-up angiographic results of flow-diverter treatment indicated a higher rate of complete occlusion (OR, 2.55; 95% CI, 1.70-3.83; P < .001) and lower rates of recurrence (OR, 0.24; 95% CI, 0.12-0.46; P < .001) and retreatment (OR, 0.31; 95% CI, 0.21-0.47; P < .001). LIMITATIONS Limitations include a retrospective, observational design in some studies, high heterogeneity, and selection bias. CONCLUSIONS Compared with the conventional endovascular treatments, the placement of a flow diverter may lead to more procedure-related complications, but there is no difference in safety, and it is more effective in the long term.

Abstract
Objective: To prospectively compare the efficacy and safety of the greenlight laser anatomical vaporization-incision technique (AVIT) and photoselective vaporization of the prostate(PVP)in the treatment of benign prostatic hyperplasia (BPH). Methods: From November 2019 to September 2020, a randomized controlled study was conducted on 136 BPH patients undergoing greenlight laser surgery in the Department of Urology, the Second Affiliated Hospital of Soochow University. The patient's age ranged from 53 to 85 years and the prostatic volume ranged from 30 to 104 ml. They were divided into two groups by random number table method,including 68 cases of AVIT(observation group)and 68 cases of PVP(control group). The clinical data of the two groups before, during and after operation were collected and analyzed. Results: Operations were successfully completed in the two groups. At 6 months after operation, 63 cases in the observation group and 66 cases in the control group completed the follow-up. There was no significant difference in the prevalence of hypertension, diabetes, coronary heart disease, atrial fibrillation and renal insufficiency between the two groups before operation (all P>0.05). The differences of preoperative age [(66.8±6.5) vs (67.3±5.4) years], international prostate symptom score (IPSS) [(24.2±4.7) vs (23.5±4.5) ], quality of life score (QOL) [4.7(4.1, 4.9) vs 4.6(4.2, 5.0)], peak urinary flow rate (Qmax) [(6.9±2.8) vs (6. 8±2.6) ml/s], post-void residual volume (PVR) [(137(52.8, 190.9) vs 119(70.6, 172.1) ml], prostate volume (PV) [70.5(60.6, 80.9) vs 68.2(61.2, 80.5) ml], serum prostate specific antigen (PSA) [4.4(3.5, 5.1) vs 4.4(3.4, 5.0) ng/ml] were not statistically significant between the two groups (all P>0.05). There was no significant difference in the amount of intraoperative blood loss, catheterization time and the postoperative hospitalization time between the two groups (all P>0.05). Compared with the control group, the operation time and lasing time of the observation group were longer[69.0(64.6, 75.0) vs 55.8(49.1, 63.4) min,(36.3±9.9) vs (31.3±9.3) min], and the intraoperaive laser energy consumption and laser energy density were higher[(297±20) vs (240±20) kJ,(4.50±1.35) vs (3.73±1.17) kJ/ml]. The differences were all statistically significant (all P<0.05). At the follow-up of 1, 3 and 6 months after operation, IPSS and QOL in the observation group were lower than those in the control group, and the differences were all statistically significant (all P<0.05). Qmax in the observation group was higher and PVR was lower than those in the control group, with statistically significant differences (P<0.05). Six months after operation, PV and PSA in the observation group decreased more significantly than those in the control group (56% vs 47%, 70% vs 60%, both P<0.05). No urethral stricture and urinary incontinence occurred in two groups after operation. The incidence rate of urinary tract irritation in the observation group was 6.3%(4/63),lower than the 18.2%(12/66)in the control group (P<0.05). There was no significant difference in the incidence rates of urinary retention, bladder neck contracture and secondary bleeding between the two groups (all P>0.05). Conclusions: Greenlight laser anatomical vaporization-incision technique is safe and effective in the treatment of BPH. Compared with PVP, AVIT has more prostate tissue removed and better curative effect, which is worthy of clinical promotion.

Abstract
Intramuscular fat content (IFC) is an essential quantitative trait of meat, affecting multiple meat quality indicators. A certain amount of IFC could not only improve the sensory score of pork but also increase the flavour, tenderness, juiciness and shelf-life. To dissect the genetic determinants of IFC, two methods, including genome-wide efficient mixed-model analysis (GEMMA) and linkage disequilibrium adjusted kinships (LDAKs), were used to carry out genome-wide association studies for IFC in Suhuai pig population. A total of 14 and 18 significant single nucleotide polymorphisms (SNPs) were identified by GEMMA and LDAK, respectively. The results of these two methods were highly consistent and all 14 significant SNPs in GEMMA were detected by LDAK. Seven of the 18 SNPs reached the genome-wide significance level (P < 9.85E-07) while 11 cases reached the suggestive significance level (P < 1.77E-05). These significant SNPs were mainly distributed on Sus scrofa chromosome (SSC) 5, 3, and 7. Moreover, one locus resides in a 2.27 Mb (71.37-73.64 Mb) region on SSC5 harbouring 13 significant SNPs associated with IFC, and the lead SNP (rs81302978) also locates in this region. Linkage disequilibrium (LD) analysis showed that there were four pairs of complete LD (r2 = 1) among these 13 SNPs, and the remaining 9 SNPs with incomplete LD (r2 ≠ 1) were selected for subsequent analyses of IFC. Association analyses showed that 7 out of 9 SNPs were significantly associated with IFC (P < 0.05) in 330 Suhuai pigs, and the other 2 SNPs tended to reach a significant association level with IFC (P < 0.1). The phenotypic variance explained (PVE) range of these 9 SNPs was 0.92-3.55%. Meanwhile, the lead SNP was also significantly associated (rs81302978) with IFC (P < 0.05) in 378 commercial hybrid pigs (Pietrain × Duroc) × (Landrace × Yorkshire) (PDLY), and the PVE was 1.38%. Besides, two lipid metabolism-relevant candidate genes, the leucine rich repeat kinase 2 (LRRK2) and PDZ domain containing ring finger 4 (PDZRN4) were identified in the 2.27 Mb region on SSC5. In conclusion, our results may provide a set of markers useful for genetic improvement of IFC in pigs and will advance the genome selection process of IFC on pig breeding programmes.

Abstract
Abstract
Study question
Is there a difference in fertility outcomes between individualized or standard FSH dosing in women scheduled for IVF with an expected poor response?
Summary answer
In predicted poor responders (AFC<10) undergoing IVF/ICSI, individualized FSH dosing does not improve ongoing pregnancy rates as compared to a standard FSH dose.
What is known already
Poor responders usually lead to many detrimental effects on IVF outcomes due to low oocyte number and quality which in turn result in low pregnancy outcomes and an increased chance of cycle cancellation. Clinicians often individualize the FSH dose using ovarian reserve tests (ORT), including antral follicle count (AFC), basal FSH (bFSH), and anti-Mullerian hormone (AMH). However, it is unclear whether individualized FSH dosing improves clinical outcomes.
Study design, size, duration
Between March 2019 and April 2020, we performed a single-center, parallel, open-label RCT in women with an AFC<10. A total of 661 women were randomized either to start FSH dosing at 300IU/225IU or 150IU. The primary outcome was live birth attributable to the first ART cycle within 18 months of randomization. In this abstract, we report ongoing pregnancy rates. Live birth date will be available at the meeting.
Participants/materials, setting, methods
Women referred for their first IVF/ICSI cycle, <43 years of age, AFC<10 were approached. A total of 328 women were allocated to the individualized group and 333 women were allocated to the standard group. In the individualized group, women with AFC 1-6 were assigned to 300IU/day (n = 122), while women with AFC 7-9 were assigned to 225IU/day (n = 206). In the standard group, women were assigned 150IU/day. Outcomes were evaluated from an intention-to-treat perspective.
Main results and the role of chance
For ongoing pregnancy rate attributable to the first ART cycle for individualized versus standard dosing was comparable [52.44% vs 46.25%, relative risk (RR): 1.29 (95%CI, 0.94-1.74), P = 0.11]. Biochemical pregnancy rate [62.50% vs 62.16%, RR: 1.01 (95%CI, 0.74-1.39), P = 0.929], clinical pregnancy rate [59.45% vs 58.86%, RR: 1.02 (95%CI, 0.75-1.40), P = 0.877] and multiple pregnancy rate [5.18% vs 5.12%, RR: 1.01 (95%CI, 0.51-2.02), P = 0.971] also did not differ between individualized and standard dosing. There are 24 women who are ongoing pregnancy but do not reach live birth in the completed embryo transfer cycle. The individualized group reported less poor response (31.1% vs 48.7%: P < 0.001), more obtained oocytes (6.80 ± 3.85 vs 5.28 ± 3.22; P < 0.001), less embryos (3.76 ± 2.70 vs 3.16 ± 2.42; P = 0.004), and less good quality embryos (2.61 ± 2.29 vs 2.21 ± 2.05; P = 0.018). When outcomes were compared over the first embryo transfer, ongoing pregnancy rates were 39.0% (128/328) versus 37.2% (124/333), respectively [RR:1.08 (95%CI, 0.79-1.48), P = 0.636], without differences in the other outcomes. There are 7 women who are ongoing pregnancy but do not reach live birth in the first embryo transfer cycle.
Limitations, reasons for caution
Due to the open-label character, potential selective canceling and small dose adjustments of standard dosing were allowed. This abstract reports on ongoing pregnancy. At the meeting, we will present live birth rates.
Wider implications of the findings
In women with predicted poor response, an increased dose does not increase ongoing pregnancy rates. A standard dose of 150IU/day is recommended in these women.

Abstract
OBJECTIVE Breast cancer (BC) is a common malignancy all over the world. However, the detailed mechanism underlying BC progression remains incompletely understood. MicroRNAs (miRNAs) have been observed to play crucial roles in tumorigenesis. The present study aimed to determine the expression and function of miR-296 in BC. PATIENTS AND METHODS MiR-296 expressions in BC tissue samples and cell lines were examined by quantitative Real Time-Polymerase Chain Reaction (qRT-PCR). After that, we performed functional assays, including MTT (3-(4,5-dimethyl thiazol-2-yl)-2,5-diphenyl tetrazolium bromide) assays and transwell assays, to show the functions of miR-296 in BC cell proliferation, invasion and migration. Immunological histological chemistry (IHC) assays were carried out to detect the expression levels of fibroblast growth factor receptor 1 (FGFR1) in BC tissue samples. Western blot was used to explore potential mechanisms of miR-296 in regulating BC progression. A Luciferase reporter assay was carried out to confirm the target gene of miR-296. RESULTS Quantitative Real Time-Polymerase Chain Reaction (qRT-PCR) results demonstrated a significant decrease of miR-296 expressions in BC when compared to the corresponding normal controls. In addition, the decreased miR-296 was correlated with the malignant phenotypes and poorer prognosis of BC patients. The functional assays indicated that miR-296 restoration could repress the proliferation, invasion and migration abilities of BC cells. Moreover, the results of the current study revealed that miR-296 exerted the repressive functions in BC cells via regulating FGFR1, the Wnt/β-catenin signaling pathway and EMT. Additionally, miR-296 up-regulation could inhibit in vivo BC cell growth. CONCLUSIONS All these findings indicated that miR-296 exerted anti-BC functions, providing novel therapeutic strategies in BC treatment.

Abstract
Abstract
Background
Bariatric surgery carries a risk of severe postoperative complications, sometimes leading to reinterventions or even death. The incidence and risk factors for reintervention and death within 90 days after bariatric surgery are unclear, and were examined in this study.
Methods
This population-based cohort study included all patients who underwent bariatric surgery in one of the five Nordic countries between 1980 and 2012. Data on surgical and endoscopic procedures, diagnoses and mortality were retrieved from national high-quality and complete registries. Multivariable Cox regression analysis was used to calculate hazard ratios (HRs), adjusted for country, age, sex, co-morbidity, type of surgery and approach, year and hospital volume of bariatric surgery.
Results
Of 49 977 patients, 1111 (2·2 per cent) had a reintervention and 95 (0·2 per cent) died within 90 days of bariatric surgery. Risk factors for the composite outcome reintervention/mortality were older age (HR 1·65, 95 per cent c.i. 1·36 to 2·01, for age at least 50 years versus less than 30 years) and co-morbidity (HR 2·66, 1·53 to 4·62, for Charlson co-morbidity index score 2 or more versus 0). The risk of reintervention/mortality was decreased for vertical banded gastroplasty compared with gastric bypass (HR 0·37, 0·28 to 0·48) and more recent surgery (HR 0·51, 0·39 to 0·67, for procedures undertaken in 2010 or later versus before 2000). Sex, surgical approach (laparoscopic versus open) and hospital volume did not influence risk of reintervention/mortality, but laparoscopic surgery was associated with a lower risk of 90-day mortality (HR 0·29, 0·16 to 0·53).
Conclusion
Reintervention and death were uncommon events within 90 days of bariatric surgery even in this unselected nationwide cohort from five countries. Older patients with co-morbidities have an increased relative risk of these outcomes.

Abstract
The utilization of thermophilic hydrocarbon-degrading microorganisms is a suitable strategy for improving biodegradation of petroleum hydrocarbons and PAHs, as well as enhancing oil recovery from high-temperature reservoirs. In this study, the thermophilic strain Aeribacillus pallidus SL-1 was evaluated for the biodegradation of crude oil and PAHs at 60 °C. Strain SL-1 was found to preferentially degrade short-chain n-alkanes (<C17) and aromatic hydrocarbons from crude oil. The highest degradation rate of 84% was obtained with 1000 mg/l naphthalene as sole carbon source. Additionally, the strain was able to degrade 80% of phenanthrene (200 mg/l) and 50% of pyrene (50 mg/l) within 5 days at 60 °C. The SL-bioemulsifier produced by strain SL-1 was identified as a glycoprotein with stable emulsifying activity over a wide range of environmental conditions. Chemical composition studies exhibited that the SL-bioemulsifier consisted of polysaccharides (65.6%) and proteins (13.1%), among them, proteins were the major emulsifying functional substrates. Furthermore, the SL-bioemulsifier was able to enhance the solubility of PAHs. Thus, the bioemulsifier-producing strain SL-1 has great potential for applications in high-temperature bioremediation.

Abstract
Background Bioemulsifiers are surface-active compounds, which exhibit advantages including low toxicity, higher biodegradability and biocompatibility over synthetic chemical surfactants. Despite their potential benefits, some obstacles impede the practical applications of bioemulsifiers, including low yields and high purification costs. Here, we aimed to exploit a novel protein bioemulsifier with efficient emulsifying activity and low-production cost, as well as proposed a design-bioemulsifier system that meets different requirements of industrial emulsification in the most economical way. Results The esterase AXE was first reported for its efficient emulsifying activity and had been studied for possible application as a protein bioemulsifier. AXE showed an excellent emulsification effect with different hydrophobic substrates, especially short-chain aliphatic and benzene derivatives, as well as excellent stability under extreme conditions such as high temperature (85 °C) and acidic conditions. AXE also exhibited good stability over a range of NaCl, MgSO4, and CaCl2 concentrations from 0 to 1000 mM, and the emulsifying activity even showed a slight increase at salt concentrations over 500 mM. A design-bioemulsifier system was proposed that uses AXE in combination with a variety of polysaccharides to form efficient bioemulsifier, which enhanced the emulsifying activity and further lowered the concentration of AXE needed in the complex. Conclusions AXE showed a great application potential as a novel bioemulsifier with excellent emulsifying ability. The AXE-based-designer bioemulsifier could be obtained in the most economical way and open broad new fields for low-cost, environmentally friendly bioemulsifiers.![]()

Abstract
BACKGROUND AND PURPOSE Subjective memory impairment (SMI) and amnestic mild cognitive impairment (aMCI) are thought to represent the pre-dementia stages of Alzheimer's disease (AD). SMI is considered a more advanced pre-clinical status prior to aMCI. Understanding the neuromechanism of SMI will have great benefits for monitoring the disease progression of AD. The study aims to explore whether SMI shows alterations of white matter (WM) integrity similar to the patterns of aMCI. METHODS The atlas-based analyses were performed to investigate the diffusion changes in the major WM tracts amongst 22 individuals with normal cognition (NC), 22 SMI patients and 25 aMCI patients. The correlations between the altered diffusion metrics and cognitive performance in the SMI and aMCI groups were assessed. RESULTS The diffusion tensor metrics of SMI were intermediate between the NC and aMCI groups. The aMCI group presented disrupted integrity in multiple WM tracts, including the left anterior thalamic radiation, right corticospinal tract and left cingulum of the hippocampus (CgH), compared to the NC group. The left CgH showed diffusion alterations in the SMI group. In the aMCI group, the mean diffusivity of the left CgH was negatively correlated with episodic memory, whilst the radial diffusivity of the right corticospinal tract was negatively correlated with executive function. No significant relationship was found in the SMI group. CONCLUSION The study suggested that SMI patients might present detectable WM integrity changes in the left CgH before exhibiting objective cognitive dysfunction, which may provide novel insights into the pathological mechanisms of AD.

Abstract
An edge toroidal charge exchange recombination spectroscopy (eCXRS) diagnostic has been deployed successfully on the Experimental Advanced Superconducting Tokamak (EAST) recently, providing edge plasma ion temperature and toroidal rotation. Edge CXRS on EAST typically monitors the carbon vi (529.059 nm, n = 8 → 7) spectral line. Spectral lines emitted from other different impurities that appeared in the wavelength ranges of 528 nm-530 nm illustrate the need to revise the edge change exchange spectra analysis in this region. Since the eCXRS sightlines end on the ion cyclotron range of frequencies (ICRF) stainless steel antenna, the passive Fe lines coming from the antenna could be recorded by eCXRS diagnostic when ICRF is used. A revised edge toroidal charge exchange spectra analysis including Fe spectral lines is presented. The accuracy of eCXRS measurement has been improved by the revised spectra analysis.

Abstract
The core toroidal charge exchange recombination spectroscopy system on experimental advanced superconducting tokamak (EAST) has been enhanced recently to extend the spectral range. The C VI charge exchange line at 529.059 nm, Ne X line at 524.897 nm, and Li III line at 516.67 nm are observed successfully. The measurements were performed by injecting neon gas and dropping lithium powder simultaneously during the 2016 EAST experimental campaign. One channel connected to a neon lamp is used to perform the real-time wavelength calibration on a shot-to-shot basis. The preliminary results indicate that ion temperature profiles from the carbon and neon impurities are in excellent agreement and provide a consistency check of the measurement from different impurities. Toroidal velocity correction associated with the energy-dependent cross section has been performed. Toroidal rotation of neon impurity is obviously faster than C VI across the whole profile. A cumulative and saturated effect of core lithium ions was observed.

Abstract
RATIONALE Hydrofluoric acid (HF) is a highly corrosive agent and can cause corrosive burns. HF can penetrate deeply into tissues through intact skin and the lipid barrier, leading to painful liquefactive necrosis, and inducing hypocalcemia and hypomagnesemia. In this study, we hypothesize that continuous renal replacement therapy (CRRT) may be beneficial in addressing hemodynamic instability in cases of HF poisoning. PATIENT CONCERNS A 25-year-old man fell into an electroplating pool containing 10% HF and 50% nitric acid. DIAGNOSES He had severe cutaneous injuries involving approximately 60% of his total body surface area including the head, face, neck, right upper arm, right hand, trunk, perineum, and both lower limbs and feet. Examination at admission showed the following electrolyte concentrations: ionic calcium 0.192 mmol/L, total calcium 0.72 mmol/L, magnesium 0.4 mmol/L, potassium 5.49 mmol/L, and sodium 136.8 mmol/L. INTERVENTIONS An initial 20 mL intravenous bolus of 10% calcium gluconate was followed by a continuous infusion at 6 g/h plus continuous intravenous drip 25% magnesium sulfate at 1.5 g/h. Continuous cardiac monitoring was performed in the intensive care unit. Extracorporeal membrane oxygenation (ECMO) was used to improve oxygenation function at 38 hours post exposure. Antibiotic therapy using imipenem/cilastin plus vancomycin was required. OUTCOMES After treatment for 12 hours, electrolyte concentrations returned to normal. On day 11, the hemodynamic parameters were stable and oxygenation function had improved. On day 26, the patient was weaned off CRRT. One month later, the patient twice received skin grafting, then was discharged from the hospital without pulmonary, cardiac, or neurological complications 3 months later. LESSONS The present case study demonstrates that CRRT may be an effective and potentially lifesaving therapy after severe exposure to HF. Prolonged hemodialysis is recommended to remove delayed release fluoride ions to avoid delayed systemic injury. When conventional therapy can not improve oxygenation and/or carbon dioxide retention, ECMO should be performed as soon as possible.

Abstract
We present the design and performance of a cryogenic scanning tunneling microscope (STM) which operates inside a water-cooled Bitter magnet, which can attain a magnetic field of up to 38 T. Due to the high vibration environment generated by the magnet cooling water, a uniquely designed STM and a vibration damping system are required. The STM scan head is designed to be as compact and rigid as possible, to minimize the effect of vibrational noise as well as fit the size constraints of the Bitter magnet. The STM uses a differential screw mechanism for coarse tip-sample approach, and operates in helium exchange gas at cryogenic temperatures. The reliability and performance of the STM are demonstrated through topographic imaging and scanning tunneling spectroscopy on highly oriented pyrolytic graphite at T = 4.2 K and in magnetic fields up to 34 T.

Abstract
This study describes a novel and efficient alasan-like bioemulsifier produced by Pseudomonas stutzeri NJtech 11-1, which was isolated from the Shengli Oilfield. The strain was found to produce a new and interesting emulsion stabilizer. The crude bioemulsifier showed super stability with 50% salinity and broad pH 3-10. The emulsion index (EI24) was increased to 100% after heating from 45 to 95 °C and the emulsion could be stable for at least 30 days. The yield of Ps-bioemulsifier (pure bioemulsifier) was 0.68 ± 0.05 mg mL-1. The Ps-bioemulsifier was composed of carbohydrates (80 ± 2.6%) and proteins (9.5 ± 0.5%). A low concentration (0.2 mg mL-1) of the Ps-bioemulsifier was obtained maximum emulsifying activity at pH 7.1 and its emulsifying activity strengthened by suitable salinity. Furthermore, Ps-bioemulsifier could also emulsify cyclohexane, hexadecane, kerosene, xylene hydrocarbons efficiently. Therefore, the Ps-bioemulsifier showed emulsifying characteristics which make it a good candidate for potential applications in bioremediation and microbial enhanced oil recovery.

Abstract
OBJECTIVE To explore the value of DNA-image cytometry (DNA-ICM) in diagnosis of lung cancer. METHODS 532 cases of bronchoalveolar lavage fluid (BALF) and (or) bronchial brushing cytology (216 cases from lung cancer patients and 209 cases from benign lung disease patients) were detected by DNA-ICM and liquid-based cytology (LBC), respectively. The sensitivity and specificity of the two methods were compared. RESULTS The sensitivity and specificity of DNA-ICM were 69.2% and 100.0%, and which of LBC were 46.7% and 97.9%, respectively. The sensitivity of DNA-ICM was significantly higher than that of LBC method in the diagnosis of lung cancer (P<0.05). The sensitivity and specificity of DNA-ICM of BALF were 71.9% and 100.0%, while those of LBC were 48.2% and 98.5%. The sensitivity and specificity of DNA-ICM of bronchial brushing cytology were 62.8% and 100.0%, while those of LBC were 43.0% and 95.3%. The sensitivity of DNA-ICM of BALF and bronchial brushing cytology were higher than that of LBC method (P<0.05). There were 107 patients who underwent BALF and bronchial brushing cytology simultaneously, the sensitivity of DNA-ICM of BALF was higher than that of bronchial brushing cytology (P<0.05). Among different histologic types of the lung cancers, the sensitivity of squamous carcinoma was higher that of adenocarcinoma. CONCLUSIONS DNA-ICM has great application value in the diagnosis of lung cancer. DNA-ICM in combination with LBC can increase the detection rate of lung cancer. DNA-ICM of BALF is worthy of application in clinical practice.

Abstract
Thiolactomycin (TLM) is a thiotetronate antibiotic that selectively targets bacterial fatty acid biosynthesis through inhibition of the β-ketoacyl-acyl carrier protein synthases (KASI/II) that catalyse chain elongation on the type II (dissociated) fatty acid synthase. It has proved effective in in vivo infection models of Mycobacterium tuberculosis and continues to attract interest as a template for drug discovery. We have used a comparative genomics approach to uncover the (hitherto elusive) biosynthetic pathway to TLM and related thiotetronates. Analysis of the whole-genome sequence of Streptomyces olivaceus Tü 3010 producing the more ramified thiotetronate Tü 3010 provided initial evidence that such thiotetronates are assembled by a novel iterative polyketide synthase-nonribosomal peptide synthetase, and revealed the identity of other pathway enzymes, encoded by adjacent genes. Subsequent genome sequencing of three other thiotetronate-producing actinomycetes, including the Lentzea sp. ATCC 31319 that produces TLM, confirmed that near-identical clusters were also present in these genomes. In-frame gene deletion within the cluster for Tü 3010 from Streptomyces thiolactonus NRRL 15439, or within the TLM cluster, led to loss of production of the respective thiotetronate, confirming their identity. Each cluster houses at least one gene encoding a KASI/II enzyme, suggesting plausible mechanisms for self-resistance. A separate genetic locus encodes a cysteine desulfurase and a (thiouridylase-like) sulfur transferase to supply the sulfur atom for thiotetronate ring formation. Transfer of the main Tü 3010 gene cluster (stu gene cluster) into Streptomyces avermitilis led to heterologous production of this thiotetronate, showing that an equivalent sulfur donor can be supplied by this host strain. Mutational analysis of the Tü 3010 and TLM clusters has revealed the unexpected role of a cytochrome P450 enzyme in thiotetronate ring formation. These insights have allowed us to propose a mechanism for sulfur insertion, and have opened the way to engineering of the biosynthesis of TLM and other thiotetronates to produce novel analogues.

Abstract
AIMS Hypoxia and high hydrostatic pressure can induce an increase in the thickness of the tunica media and intima; secondary vasa vasorum (VV) increase to fit the remodeling of the vessel wall. We aimed to investigate the impact of high hydrostatic pressure on VV in the varicose greater saphenous veins (VGSVs) and diseased splenic veins (DSVs). METHODS We collected 34 VGSVs and DSVs. Thirty-four normal greater saphenous veins (GSVs) and splenic veins (SVs) were also collected (control group). Samples were cut into slices, and observed under both light and electron microscopy. The mean density and cross-sectional areas of the VV in the adventitia were measured. RESULTS In both VGSVs and DSVs, VV density increased, in the adventitia and exterior tunica media, offering an intensive linear distribution. However, sporadic distribution of the interior tunica media and intima were seen on light microscopy. The integrated structure of the cell nucleus of endothelial cells in VV, normal morphology and distribution of chromatin, partially hyperchromatic mitochondria matrix, fuzzy or fractured mitochondria cristae, and medullary cristae changes were observed by electron microscopy. Mean density and cross-sectional areas of VV in the adventitia of GSVs and SVs were significantly different. CONCLUSION Under high hydrostatic pressure conditions, the number of VV were increased in the wall of VGSVs and DSVs. There was heterogeneity between both types of veins. The splenic vein has a higher number of VV, but the greater saphenous vein has a higher average cross-sectional area. The same ultrastructural changes are seen in the endothelial cells of the VV in both vessels.

Abstract
Following intracerebral hemorrhage (ICH), high-mobility group box 1 protein (HMGB1) may promote vascular remodeling. Whether HMGB1 supports angiogenesis after ICH is unclear, as are the receptors and downstream signaling pathway(s) involved. We used the rat model of collagenase-induced ICH to determine whether HMGB1 acts via the receptor for advanced glycation end-products (RAGE) to upregulate vascular endothelial growth factor (VEGF), a potent mitogen of endothelial cells and key regulator of normal and abnormal angiogenesis in the late phase of injury. At 3d after ICH induction, rats were treated with saline, ethyl pyruvate (EP) or N-benzyl-4-chloro-N-cyclohexylbenzamide (FPS-ZM1). ICH induced the movement of HMGB1 from the nucleus into the cytoplasm. Levels of HMGB1 and RAGE in the ipsilateral striatum increased within a few days of induction and continued to rise for 7-14d afterward. By 14d after induction, levels of VEGF and vessel density were higher than in the Sham group. Administering EP 3 days after ICH induction prevented much of the stroke-induced increases in vessel density and in expression of HMGB1, RAGE, and VEGF. Administering FPS-ZM1 after ICH blocked much of the stroke-induced increases in vessel density and VEGF expression. Our results suggest that after ICH, HMGB1 may upregulate VEGF in the ipsilateral striatum predominantly via RAGE. Hence, targeting the HMGB1/RAGE signaling pathway may help reduce inappropriate angiogenesis after ICH.

Abstract
PURPOSE To observe the effects of cyclopamine on the biological characteristics of human breast cancer MCF-7 cell line and explore its mechanism. MATERIALS AND METHODS After human breast cancer MCF-7 cells were treated with different-concentration cyclopamine for different periods, MTT assay was used to detect the inhibitory effect of cyclopamine on MCF-7 cell proliferation, flow cytometry was used to determine the distribution of MCF-7 cell cycle and the effect of cyclopamine on MCF-7 apoptosis, and Western blot was used to measure the protein levels of cyclins D1 and p21 in MCF-7 cells. RESULTS In certain range, MCF-7 cell proliferation was inhibited by cyclopamine in a dose- and time-dependent manner, and the optimal inhibiting concentration was ten µmol/L and the optimal action time at 48 hours. With the time prolongation of cyclopamine action, the cells in G0/G1 phase were significantly increased, but the cells in S phase were significantly decreased (compared with blank control group, allp < 0.05). With the time prolongation of cyclopamine action, apoptosis rate of MCF-7 cells was also significantly increased (compared with blank control group, allp < 0.05). The level of cyclin D1 of MCF-7 cells was decreased, but cyclin p21 was increased (compared with blank control group, all p < 0.05). CONCLUSION Cyclopamine inhibits MCF-7 cell proliferation via arresting MCF-7 cell transformation from G1 phase to S phase. This may be associated with the expressions of Hedgehog (Hh) signaling pathway-related cyclins.

Abstract
Approximately 60% of women who labour in the USA receive some form of neuraxial analgesia, but concerns have been raised regarding whether it negatively impacts the labour and delivery process. In this review, we attempt to clarify what has been established as truths, falsities and uncertainties regarding the effects of this form of pain relief on labour progression, negative and/or positive. Additionally, although the term 'epidural' has become synonymous with neuraxial analgesia, we discuss two other techniques, combined spinal-epidural and continuous spinal analgesia, that are gaining popularity, as well as their effects on labour progression.

Abstract
OBJECTIVES: This study investigated spontaneous dorsal horn potentials in patients with pain after brachial plexus avulsion and determined the effect of dorsal root entry zone (DREZ) lesioning on these potentials and on pain levels. METHODS: Electrospinography (ESG) recordings were undertaken in seven patients using a noninvasive electrocorticography strip electrode. Measurements were taken from the DREZ on the intact side of the spinal cord before lesioning of the injured DREZ and from the injured DREZ before and after lesioning. RESULTS: DREZ lesioning had a significant positive effect on pain at 12 months postoperatively. At 15.0 Hz, the mean ESG power from the injured DREZ before lesioning was significantly higher than that from the intact DREZ. In addition, the mean ESG power from the injured DREZ after successful DREZ lesioning was significantly lower than that from the intact DREZ and that from the injured DREZ before lesioning. CONCLUSIONS: The ESG power from the injured DREZ increases in patients with pain after brachial plexus avulsion compared with that of the intact DREZ; this increase is reduced by successful DREZ lesioning.

Abstract
AIMS Remogliflozin etabonate (RE) is the pro-drug of remogliflozin (R), a selective inhibitor of renal sodium-dependent glucose transporter 2 (SGLT2) that improves glucose control via enhanced urinary glucose excretion (UGE). This study evaluated the safety, tolerability, pharmacokinetics and pharmacodynamics of repeated doses of RE in subjects with type 2 diabetes mellitus (T2DM). METHODS In a double-blinded, randomized, placebo-controlled trial, subjects who were drug-naïve or had metformin discontinued received RE [100 mg BID (n = 9), 1000 mg QD (n = 9), 1000 mg BID (n = 9)], or placebo (n = 8) for 12 days. Safety parameters were assessed, including urine studies to evaluate renal function. Plasma concentrations of RE and metabolites were measured with the first dose and at steady state. RE effects on glucose levels were assessed with fasting glucose concentrations, frequently sampled 24-h glucose profiles and oral glucose tolerance tests. RESULTS No significant laboratory abnormalities or safety events were reported; the most frequent adverse events were headache and flatulence. Plasma exposure to RE and R were proportional to administered dose with negligible accumulation. Mean 24-h UGE increased in RE treatment groups. Compared with the placebo group, 24-h mean (95% CI) changes in plasma glucose were -1.2 (-2.2 to -0.3) (100 mg BID), -0.8 (-1.7 to 0.2) (1000 mg QD) and -1.7 (-2.7 to -0.8) mmol/l (1000 mg BID). CONCLUSIONS Administration of RE for 12 days is well-tolerated and results in clinically meaningful improvements in plasma glucose, accompanied by changes in body weight and blood pressure in subjects with T2DM.
