Abstract
BACKGROUND Residual limb neuromas are a significant cause of post-amputation pain. There is little knowledge concerning ultrasound-guided (US) radiofrequency ablation (RFA) as treatment. OBJECTIVE To investigate US-guided RFA for neuroma associated pain in individuals with limb amputation. METHODOLOGY The notes of nine consecutive patients were retrospectively reviewed. Information obtained included neuroma size and nerve, RFA duration/temperature, pain scores, analgesic requirements and ease/comfort of prosthetic use. Eight patients had lower-limb amputations and one had a trans-radial amputation. All except one, underwent diagnostic US-guided steroid injection to confirm the neuroma as the source of pain, prior to RFA. RESULTS Six patients reported significant reduction in pain scores (defined as at least 50% reduction) and an improvement in comfort/ease of wearing their prosthetic limb, with no adverse effects. Three of these six patients also reported a reduction in analgesic requirements. Of the three remaining patients - one had a large sciatic nerve neuroma that was eventually surgically excised, another had confounding pain from an adjacent bony spur, whilst the third patient did not receive a routine diagnostic steroid injection prior to RFA. CONCLUSIONS Our findings suggest that US-guided RFA is safe and effective for small to medium-sized residual limb neuroma associated pain in individuals with limb amputation. It can reduce pain and analgesic requirements, improve comfort/ease of wearing the prosthesis and potentially avoid surgical excision. We recommend patients should undergo a diagnostic steroid injection prior to RFA to confirm that the neuroma is the source of pain.

Abstract
Abstract
Objective
Cardiopulmonary bypass-associated acute kidney injury (CPB-AKI) is a frequent complication after cardiac surgery in children patients. Intraoperative hybrid cardiac surgery (IPH) is a new technique which needed contrast administration. Contrast was also reported to induce AKI. Therefore, we hypothesized that the IPH would increase the occurrence of CPB-AKI in children Congenital heart disease patients.
Methods
A total of 1509 consecutive patients (age≤3 year) undergoing on-pump cardiac surgery were enrolled in this study from November, 2017 to May, 2018. Multivariate logistic regression was performed in this retrospective study. Propensity score matched analysis was applied for confounding factors. Perioperative and interoperative characteristics and outcomes in IHP group with or without AKI are compared. CPB-AKI was determined by serum Creatinine (SCr) increased twice as much as preoperative or need dialysis within 7 days postoperatively.
Result
IPH was found to be an independent risks factor in the development of CPB-AKI development (OR 2.798, 95% CI 1.823–4.296, p<0.001). Other independent risk factors for CSA-AKI were: CPB time >100 min (OR 2.068, 95% CI 1.521–2.811, P<0.001), weight≤5 kg (OR 3.409, 95% CI 2.192–5.302, P<0.001). Cohort analysis revealed that AKI occurred more frequently in the IPH group before and after matching (30.4% vs. 12.97%, P<0.001; 32.2% vs. 18.3% %, P=0.015, respectively). IPH group also had higher prolonged length of postoperative stay in the hospital (11 vs 7.5, P<0.001; 10.9 vs 7.7, p=0.01), and higher length of mechanical ventilation support (27 vs 10, P<0.001; 26 vs 16, <0.001) before and after matching. Perioperative and interoperative characteristics and outcomes of patients with or without AKI are compared. Only CPB duration was an independent factor for AKI in IPH group.

Abstract
BACKGROUND AND PURPOSE Previous DTI cross-sectional studies have showed the cerebral damage feature was different in the three clinical stages after carbon monoxide poisoning. Diffusional kurtosis imaging (DKI) is an advanced diffusion imaging model and considered to better provide microstructural contrast in comparison with DTI parameters. The primary aim of this study was to assess microstructural changes in gray and white matter with diffusional kurtosis imaging in the acute, delayed neuropsychiatric, and chronic phases after acute carbon monoxide (CO) poisoning. The secondary aim was to relate diffusional kurtosis imaging measures to neuropsychiatric outcomes of acute carbon monoxide poisoning. MATERIALS AND METHODS In all, 17 patients with acute carbon monoxide poisoning and 30 sex- and age-matched healthy volunteers were enrolled in the study. Patients were scanned within 1 week, 3-8 weeks, and 6 months after acute carbon monoxide poisoning. Diffusional kurtosis imaging metrics including mean kurtosis, mean diffusivity, fractional anisotropy, and kurtosis fractional anisotropy were measured in 11 ROIs and then further correlated with neuropsychiatric scores. RESULTS In WM, mean kurtosis tended to increase from the acute-to-delayed neuropsychiatric phases and then decrease in the chronic phase, while in GM mean kurtosis showed a constant decline. Contrary to mean kurtosis, mean diffusivity first decreased then tended to increase in WM, while in GM, from the acute to chronic phases, mean diffusivity showed a constant increase. In both WM and GM, the fractional anisotropy and kurtosis fractional anisotropy values progressively declined with time. Kurtosis fractional anisotropy showed the best diagnostic efficiency with an area under the curve of 0.812 (P = .000). Along with neuropsychiatric scores, kurtosis fractional anisotropy of the centrum semiovale and Digit Span Backward were most relevant (r = 0.476, P = .000). CONCLUSIONS Longitudinally, microstructural changes were inconsistent in WM and GM with time after acute carbon monoxide poisoning. Diffusional kurtosis imaging metrics provided important complementary information to quantify the damage to cognitive impairment.

Abstract
SummaryChronic nasal-sinusitis is a chronic inflammatory disease characterized by persistent inflammation in the nasal and nasal mucosa. The pathogenesis of CRS is extremely complex and there is currently a lack of effective therapy. The reason for inaccurate diagnosis and invalid treatment of CRS is its sophisticated and unclear mechanism. The pathogenesis of CRS from Asian populations is neutrophil infiltration mediated by Th1/Th17 mixture. Consequently, exploring the function of neutrophil in the pathogenesis of CRS plays an important role in clinical diagnosis and treatment for CRS patients in China.

Abstract
1. Adipocyte fatty acid binding protein (A-FABP) plays a key role in fatty acid uptake and intracellular transport. The objective of the present study was to identify and characterise the A-FABP gene in Xupu goose.2. The full-length cDNA of goose A-FABP gene was cloned from the liver tissue using reverse transcription polymerase chain reaction (RT-PCR) and rapid amplification of cDNA ends (RACE). The distribution of the goose A-FABP in different tissues was determined by quantitative real-time PCR (qRT-PCR).3. The results showed that the full-length cDNA sequence of goose A-FABP was 657 bp, containing a 5'-UTR of 52 bp, a 3'-UTR of 206 bp and an open reading frame (ORF) of 399 bp, which encoded a polypeptide of 132 amino acids (AA).4. The AA sequence of goose A-FABP showed 76.52%, 75.00%, 93.18% and 99.24% identities with previously described homologues from humans (Homo sapiens), mouse (Mus musculus), chicken (Gallus gallus), and duck (Anas platyrhynchos), respectively, and phylogenetic analysis revealed a close relationship among them. The transcript of Xupu goose A-FABP was ubiquitously expressed in all tested tissues, and showed a high-level expression in abdominal fat, sebum and liver.5. A significant positive correlation was identified between A-FABP mRNA abundance in the three adipose tissues and liver weight, ratio of liver to body weight, TG content, and VLDL concentration in the plasma of Xupu goose. A significant negative correlation was observed between the mRNA level of A-FABP and HDL concentration in the plasma of Xupu goose.6. These findings provide a foundation for further research on the function and mechanism of A-FABP in the fat deposition process.

Abstract
A lamellar (L12 + B2) AlCoCrFeNi2.1 eutectic high entropy alloy (EHEA) was severely deformed by a novel hybrid-rolling process. During hybrid-rolling, the deformation was carried out in two stages, namely cryo-rolling followed by warm-rolling at 600 °C. The strain (ε) imparted in each of these steps was identical ~1.2, resulting in a total strain of ε~2.4 (corresponding to 90% reduction in thickness). The novel processing strategy resulted in an extremely heterogeneous microstructure consisting of retained lamellar and transformed nanocrystalline regions. Each of these regions consisted of different phases having different crystal structures and chemical compositions. The novel structure-composition dual heterogeneous microstructure originated from the stored energy of the cryo-rolling which accelerated transformations during subsequent low temperature warm-rolling. The dual heterogeneous microstructure yielded an unprecedented combination of strength (~2000 MPa) and ductility (~8%). The present study for the first time demonstrated that dual structure-composition heterogeneities can be a novel microstructural design strategy for achieving outstanding strength-ductility combination in multiphase high entropy alloys.

Abstract
Background Cervical cancer is the 2nd most common malignant tumour in women worldwide. Previous research studies have given little attention to its prognostic factors in the rapidly growing Asian American population. In the present study, we explored prognostic factors in Asian and white American patients with cervical cancer, considering competing risks. Methods The study included 58,780 patients with cervical cancer, of whom 54,827 were white and 3953 were Asian American, and for all of whom complete clinical information was available in the U.S. Surveillance, Epidemiology, and End Results database. Death from cervical cancer was considered to be the event of interest, and deaths from other causes were defined as competing risks. The cumulative incidence function and the Fine-Gray method were applied for univariate and multivariate analysis respectively. Results We found that, for all patients (white and Asian American combined), the cumulative incidence function was associated with several factors, such as age at diagnosis, figo (Fédération internationale de Gynécologie et d'Obstétrique) stage, registry area, and lymph node metastasis. Similar results were found when considering white patients only. However, for Asian American patients, registry area was not associated with the cumulative incidence function, but the other factors (for example, figo stage) remained statistically significant. Similarly, in multivariate analyses, we found that age at diagnosis, figo stage, lymph node metastasis, tumour histology, treatment method, and race were all associated with prognosis. Conclusions Survival status differs for white and Asian American patients with cervical cancer. Our results could guide the treatment of, and facilitate prognostic judgments about, white and Asian American patients with cervical cancer.

Abstract
OBJECTIVE Paraquat (PQ) poisoning is a significant cause of mortality and morbidity in developing countries. Poor prognostic outcomes have been attributed to the herbicide's toxicity and the lack of effective treatments. Our study aims to investigate the changes in lymphocyte count in both patients who survived and died from PQ poisoning and explore the prognostic value. METHOD This is a retrospective case serials observational study. Adult patients admitted with acute PQ poisoning. The notes of 1000 patients who presented with acute PQ poisoning were reviewed. One hundred thirty patients having the T lymphocyte met the inclusion criteria and were grouped into those that survived the poisoning (95) and non-survivors (35). RESULTS On admission, non-survivors had a higher ingestion volume of PQ and urine PQ concentration as well as higher severity indices (Acute Physiology and Chronic Health Evaluation 2, Sequential Organ Failure Assessment, and Poisoning Severity Score). Patients in the survival group had a higher dosage of immunosuppressant and a longer hospital stay. Leukocytes, especially neutrophils, were higher among non-survivors; however, the converse was found with lymphocytes. T lymphocyte (CD3) count was consistently higher among survivors as well as the subgroups CD4+ and CD8+. No differences in the ratio of CD4/CD8 were found between the groups. CONCLUSION Our study has shown that changes in lymphocyte count as its subgroups could indicate a host's immune status and lymphocytes play an important role as a surrogate marker of host immunity, which could be a useful prognostic tool in the assessment of this disease.

Abstract
Objective: To summarize the clinical data including manifestations, diagnosis, treatment and prognosis of eosinophilic gastroenteritis (EGE) in children. Methods: A retrospective analysis was performed in 71 patients with pathologically proven EGE at Beijing Children's Hospital Affiliated to Capital Medical University from January 2008 to January 2017. Their clinical manifestations, laboratory and imaging examinations, endoscopic findings, histopathological examinations, and treatment were collected and analyzed. Results: Among 71 EGE cases, 47 (66%) cases were male and 24 (34%) cases were female, and the median age was 9.2 (0.2-16.5) years old. The main clinical manifestations included abdominal pain (76%, 54/71), vomiting (68%, 48/71), anorexia (54%, 38/71), weight loss (38%, 27/71), and diarrhea (37%, 26/71). There were 27 cases (38%) with a history of allergic diseases or family history. The median absolute value of eosinophil in peripheral blood of the 71 patients was 0.4 (0-36.8)×10(9)/L, and 27 cases (38%) showed an increase in eosinophil counts. Serum IgE was measured in 52 patients (104.3 (3.4- 3 000.0)×10(3) U/L), and 30 patients (58%) showed an increase in serum IgE. A large number of eosinophils ((41.0±8.5)/HP) were found in 3 patients' ascites. The endoscopic examination of upper gastrointestinal tract revealed hyperemic edema in 62 cases (87%), plaque in 44 cases (62%), erosion in 17 cases (24%) and ulceration in 16 cases (23%). Histopathologically, in 8 cases (11%) the disease involved both stomach and duodeneum, in 21 cases (30%) involved stomach only, and in 37 cases (52%) involved duodeneum only. In addition, in 6 cases (8%) the disease involved esophagus and in 10 cases (14%) involved colorectum. Microscopically, eosinophil counts averaged 67/HP, 33/HP, 40/HP and 38/HP in esophageal, gastric, duodenal and colorectal mucosa respectively. A total of 34 cases were treated with glucocorticoid, and all these patients had alleviation of symptoms, which occurred within 14.9 days on average, but EGE recurred in 11 cases (32%). Conclusions: The clinical symptoms and endoscopic findings of EGE are diverse and nonspecific. Histopathological examination of gastrointestinal mucosa is particularly important for the diagnosis. Glucocorticoid treatment is effective, but the patients with EGE are prone to relapse.

Abstract
PURPOSE The purpose of this study was to explore the differences between stage T2N0M0 and stage T1N1M0 gastric cancer (GC) and to identify the necessity of adjuvant treatment (AT) for these stages. METHODS Between years 2004 and 2015, 1971 stage IB GC patients who underwent radical surgery were recruited using the Surveillance, Epidemiology and End Results database. We conducted univariate/multivariate analyses, the propensity score matching and evaluated gastric cancer-specific survival (GCSS) and overall survival (OS) with the log-rank test. RESULTS T1N1M0 had a significantly worse survival than T2N0M0 in both GCSS and OS before and after the propensity score matching. Examined lymph nodes (ELN) ≤ 15 and T1N1M0 were independent risk factors for worse GCSS and OS in stage IB GC. The absence of adjuvant chemotherapy (CT) was an independent risk factor for worse GCSS and OS in T1N1M0 but not in T2N0M0. AT demonstrated similar GCSS and OS with surgery alone (SA) for T2N0M0 but better survival for T1N1M0. Compared to CT and adjuvant chemoradiotherapy (CRT) group, SA demonstrated significantly worse GCSS and OS for T1N1M0. There was no significant difference between CT and CRT in both T2N0M0 and T1N1M0 stages. T2N0M0 had a better survival than T1N1M0 in ELN ≤ 15 subgroup. However, similar survival was demonstrated in ELN > 15 subgroup. CONCLUSIONS T2N0M0 GC has a better survival rate than T1N1M0 GC when ELN are ≤ 15. Moreover, T2N0M0 GC may not benefit from AT. T1N1M0 GC requires CT but not adjuvant radiotherapy.

Abstract
Chemokine (C-X-C motif) ligand 1 (CXCL1), a member of the CXC chemokine family, has been reported to be a critical factor in inflammatory diseases and tumor progression. However, its functions and molecular mechanism in estrogen receptor α (ER) negative breast cancer (BC) has little been known. In this study, we discovered that CXCL1 is overexpression in ER-negative breast cancer tissues and cell lines compared with ER-positive patient tissues and cell lines. Treatment with recombinant human CXCL1 protein promotes ER-negative BC cell migration and invasion in dose-dependent manner and stimulates the activation of p-ERK1/2, but not p-STAT3 or p-AKT. Whereas, knockdown of CXCL1 in BC cells attenuates these effects. Moreover, CXCL1 induces the expression of MMP2/9 via ERK1/2 pathway. The blockage of ERK by its antagonists (U0126) can abolish the effect of CXCL1 on MMP2/9 expression. Furthermore, immunohistochemical (IHC) analysis revealsa strong positive correlation between CXCL1 and p-ERK1/2 expressions in BC tissues. In conclusion, our study illustrates that CXCL1 is highly expressed in ER-negative BC and stimulates cell migration and invasion through ERK/MMP2/9 pathway, which may serve as a potential therapeutictarget in ER-negative breast cancer.

Abstract
OBJECTIVE To investigate the role of long non-coding RNA Cancer Susceptibility Candidate 15 (CASC15) in cervical cancer and its potential molecular mechanism. PATIENTS AND METHODS The CASC15 expression was measured in cervical cancer tissues and cell lines by using quantitative Real-time polymerase chain reaction (qRT-PCR) analysis. Cell counting kit-8 (CCK8), flow cytometry analysis and transwell cell invasion assays were employed to detect the capacities of cell proliferation and cell invasion. Furthermore, Western blot analysis was applied to detected the E-cadherin and N-cadherin expression in EMT pathway. RESULTS We demonstrated that lncRNA CASC15 expression was higher in cervical cancer tissues compared to adjacent normal tissues. Higher lncRNA CASC15 expression associated with lymph node metastasis and FIGO stage. Moreover, our results showed that higher lncRNA CASC15 expression predicted poor prognosis of cervical cancer. Functional assays showed that knockdown of lncRNA CASC15 suppressed cell proliferation and cell cycle progression in cervical cancer. Moreover, we also found that knockdown of lncRNA CASC15 inhibited cell invasion ability and Epithelial-Mesenchymal Transition (EMT) signaling pathway by upregulating E-cadherin and downregulating N-cadherin expression in cervical cancer. CONCLUSIONS These results indicated that lncRNA CASC15 expression may be a prognostic biomarker and contributed to cell proliferation and invasion in cervical cancer.

Abstract
Addition of peginterferon alpha (PEG-IFN add-on) to entecavir (ETV) treatment after a short lead-in phase results in more response than ETV monotherapy in HBeAg-positive chronic hepatitis B infection (CHB). This study is the first to assess long-term efficacy of this treatment strategy. Patients who received ETV ± 24 weeks of PEG-IFN add-on in a global trial (ARES study) and completed follow-up were eligible to participate in this observational LTFU study if they had at least one combined HBeAg and HBV DNA measurement beyond week 96 of the ARES study. The primary endpoint was combined response (HBeAg loss and HBV DNA <200 IU/mL) at LTFU. In total, 48 patients treated with PEG-IFN add-on and 48 patients treated with ETV monotherapy were included. The median follow-up duration was 226 (IQR 51) weeks, and 86/96 (90%) patients were initial non-responders. At LTFU, combined response was present in 13 (27%) vs 11 (23%) patients (P = 0.81), and 1 log10 HBsAg decline in 59% vs 28% (P = 0.02) for PEG-IFN add-on and ETV monotherapy, respectively. In 41 initial non-responders who continued ETV therapy, combined response at LTFU was present in 9 patients (PEG-IFN add-on: 5/22 [23%]; ETV monotherapy: 4/19 [21%]). Beyond week 96 of follow-up, rates of serological response became comparable between PEG-IFN add-on and ETV monotherapy. Although in this LTFU study initial non-responders were overrepresented in the add-on arm, PEG-IFN add-on possibly leads rather to accelerated HBeAg loss than to increased long-term HBeAg loss rates.

Abstract
This case series reviews previous publications and reports four feline spinal epidural empyema cases that presented with non-ambulatory thoracolumbar myelopathy. Two cats underwent myelography and two MRI. Bacteria were obtained in three cases, in two from epidural abscesses and from a tail base wound in one; histopathological examination of epidural tissue showed pyogranulomatous changes in the remaining cat. Three cats were treated by surgical decompression plus antimicrobial therapy and one cat was treated medically. All cats showed satisfactory improvement following treatment over a follow-up period of 3 months. Spinal epidural empyema is a rare condition but all cats in this series had favourable outcomes.
