Abstract
Introduction Most cochlear implant (CI) users have difficulty in listening tasks that rely strongly on perception of frequency changes (e.g., speech perception in noise, musical melody perception, etc.). Some previous studies using behavioral or subjective assessments have shown that short-term music training can benefit CI users’ perception of music and speech. Electroencephalographic (EEG) recordings may reveal the neural basis for music training benefits in CI users. Objective To examine the effects of short-term music training on CI hearing outcomes using a comprehensive test battery of subjective evaluation, behavioral tests, and EEG measures. Design Twelve adult CI users were recruited for a home-based music training program that focused on attentive listening to music genres and materials that have an emphasis on melody. The participants used a music streaming program (i.e., Pandora) downloaded onto personal electronic devices for training. The participants attentively listened to music through a direct audio cable or through Bluetooth streaming. The training schedule was 40 min/session/day, 5 days/week, for either 4 or 8 weeks. The pre-training and post-training tests included: hearing thresholds, Speech, Spatial and Qualities of Hearing Scale (SSQ12) questionnaire, psychoacoustic tests of frequency change detection threshold (FCDT), speech recognition tests (CNC words, AzBio sentences, and QuickSIN), and EEG responses to tones that contained different magnitudes of frequency changes. Results All participants except one finished the 4- or 8-week training, resulting in a dropout rate of 8.33%. Eleven participants performed all tests except for two who did not participate in EEG tests. Results showed a significant improvement in the FCDTs as well as performance on CNC and QuickSIN after training (p < 0.05), but no significant improvement in SSQ scores (p > 0.05). Results of the EEG tests showed larger post-training cortical auditory evoked potentials (CAEPs) in seven of the nine participants, suggesting a better cortical processing of both stimulus onset and within-stimulus frequency changes. Conclusion These preliminary data suggest that extensive, focused music listening can improve frequency perception and speech perception in CI users. Further studies that include a larger sample size and control groups are warranted to determine the efficacy of short-term music training in CI users.

Abstract
PURPOSE In peripheral artery disease, blockage of the blood supply to the limbs leads to blood flow attenuation and tissue ischemia. We investigated whether growth hormone-releasing hormone (GHRH) could enhance the biological functions and therapeutic effects of endothelial progenitor cells (EPCs) derived from adult human peripheral blood (PB). METHODS EPCs were isolated from human PB (PB-EPCs) and cord blood and expanded in vitro. PB-EPCs incubated with or without GHRH were evaluated for proliferation, migration, and angiogenesis capacity and apoptosis rates under oxidative stress conditions. Activation of STAT3 and Akt pathways was evaluated using Western blot. A hind-limb ischemia (HLI) mouse model was used to study the efficacy of GHRH in improving EPC therapy in vivo. RESULTS GHRH enhanced the proliferation, migration, and angiogenesis capacity of PB-EPCs and reduced apoptosis under H2O2 stimulation. These beneficial effects were GHRH receptor-dependent and were paralleled by increased phosphorylation of STAT3 and Akt. Transplantation of GHRH-preconditioned EPCs into HLI model mice enhanced blood flow recovery by increasing vascular formation density and enhanced tissue regeneration at the lesion site. CONCLUSION Our studies demonstrate a novel role for GHRH in dramatically improving therapeutic angiogenesis in HLI by enhancing the biological functions of EPCs. These findings support additional studies to explore the full potential of GHRH in augmenting cell therapy for the management of ischemia.

Abstract
Objective: To investigate the clinicopathological manifestations, molecular genetic, diagnostic histology and differential diagnosis of alveolar soft part sarcoma (ASPS) in children. Methods: A total of 13 cases of ASPS diagnosed at Beijing Children's Hospital from August 2009 to November 2018 were collected. HE staining, histochemical staining for PAS and D-PAS, immunohistochemical (IHC) staining for TFE3, INI1 and CD68 and florescence in situ hybridization (FISH) for TFE3 gene translocation were performed. Results: There were four males and nine females, age ranged from 1 year and 2 months to 13 years and 8 months (mean 7.8 years); and four patients were under 5 years old. Histologically, the tumors showed a distinctive and characteristic nested or organoid growth pattern (11 cases) or solid, diffuse growth (2 cases). The tumor cells possessed abundant eosinophilic, or glycogen-rich and clear to vacuolated cytoplasm. The chromatin was relatively dispersed, with prominent and pleomorphic nucleoli; mitotic figures were rare. Vascular invasion was frequently seen. IHC staining showed specific nuclear TFE3 staining. The tumor cells were also positive for INI1,CD68 and vimentin; but were negative for MyoD1, Myogenin, CK and S-100 protein. Seven cases showed PAS and D-PAS staining, with fuchsia acicular or rod-shaped crystals in tumor cytoplasm. Nine cases showed TFE3 break-apart signals by FISH. Conclusions: ASPS is a rare soft tissue sarcoma in children. Compared with ASPA in adults, it has both similarities and unique clinicopathologic characteristics. The diagnosis needs to be confirmed by combining clinical, pathologic, IHC and genetic testing.

Abstract
Some patients with Robin sequence (RS) may respond to conservative therapy, while others require surgery; however, there are currently no objective anatomical criteria to gauge surgical indication. The purpose of this study was to explore the imaging characteristics of the mandible and upper respiratory tract in children with RS and examine how individual morphometric parameters influence the treatment strategy. Cone beam computed tomography (CBCT) images were obtained from 57 children with RS. Twenty parameters were measured as potential surgical indicators. The children were divided into two groups according to surgical requirement: a non-surgical group (26 children) and a surgical group (31 children who underwent mandibular osteodistraction). Differences in the imaging parameters were compared between the groups. The mandibular ramus was shorter bilaterally (left, P = 0.047; right, P = 0.027) and the mandibular body was longer bilaterally (left, P = 0.030; right, P = 0.025) in the surgical group when compared to the non-surgical group. In addition, the mandibular angle bilaterally (left, P = 0.023; right, P = 0.003) and the cross-sectional area at the epiglottis tip (P = 0.010) were smaller in the surgical group. Compared to RS patients receiving conservative treatment, children requiring surgery have specific anatomical features of the mandible and upper airway that can be used as surgical indications.

Abstract
OBJECTIVE To observe the effects of different doses of propofol on the growth of transplanted liver tumor in BALB/C mice and check the expression of PCNA, CD34 and pAKT proteins to clarify the mechanism on molecule level. METHOD Human primary liver cancer cells SMMC-7721 were subcutaneously cultured in BALB/C mice, and the transplanted tumor model of BALB/C mice was constructed. Forty mice successfully modeled were randomly divided into 5 groups (n = 8): the blank control group (group C), low-fat milk group (group I), low-dose (50 mg/kg) propofol group (P1), middle-dose (100 mg/kg) propofol group (P2) and high dose (150 mg/kg) propofol group (P3). Tumor volume changes were observed at 3, 6, 9, 12, 15 and 18 days (T1, T2, T3, T4, T5, T6 and T7) before and after administration of the drug, and tumor growth curves were plotted. After 19 days of administration, all mice were killed for tumor collection, tumor weight was measured, and the tumor inhibition rate of propofol was calculated. The protein expression of cluster of differentiation 34 (CD34) in transplanted tumor was detected by immunohistochemistry, and the protein expression of proliferating cell nuclear antigen (PCNA) and phospho-Akt (pAKT) was detected by immunofluorescence. RESULTS Compared with group C, there was no significant difference in tumor volume in group I. At T2 ~ 7, the tumor volume of group P1, P2 and P3 decreased successively (P < 0.05). There was no significant difference in the inhibitory rate of tumor in group I, and the inhibitory rate of tumor in group P1, P2 and P3 increased successively (P < 0.05). There was no significant difference in PCNA, CD34, and pAKT protein expression in group I, while PCNA, CD34, and pAKT protein content in P1, P2, P3 groups were successively decreased (P < 0.05). CONCLUSION Propofol had a dose-dependent effect on the growth of liver cancer xenografts in mice, inhibiting the expression of PCNA, CD34 and pAKT proteins, and the effect was most obvious in the 150 mg/kg propofol group.

Abstract
In prospective cohort study, multi follow up is often necessary for study subjects, and the observed values are correlated with each other, usually resulting in time-dependent confounding. In this case, the data generally do not meet the application conditions of traditional multivariate regression analysis. Sequential conditional mean model (SCMM) is a new approach that can deal with time-dependent confounding. This paper mainly summarizes the basic theory, steps and characteristics of SCMM.

Abstract
Black men bear a disproportionate burden of HIV infection. These HIV inequities are influenced by intersecting social, clinical, and behavioral factors. The purpose of this analysis was to determine the combinations of factors that were most predictive of HIV infection and HIV testing among black men in Toronto. Classification and regression tree analysis was applied to secondary data collected from black men (N = 460) in Toronto, 82% of whom only had sex with women and 18% whom had sex with men at least once. For HIV infection, 10 subgroups were identified and characterized by number of lifetime male partners, age, syphilis history, and perceived stigma. Number of lifetime male partners was the best single predictor of HIV infection. For HIV testing, the analysis identified 8 subgroups characterized by age, condom use, number of sex partners and Chlamydia history. Age (>24 years old) was the best single predictor of HIV testing.

Abstract
Objective: To explore the incidence and clinical characteristics of sarcopenia in hospitalized elderly patients with coronary heart disease and search for the related factors. Methods: This study was a single-center observational study. According to the inclusion criteria, elderly patients hospitalized with coronary heart disease from Peking Union Medical College Hospital between December 2017 and December 2018 were enrolled. The patients were divided into sarcopenic group and non-sarcopenic group according to the diagnostic criteria of the Asian Working Group for Sarcopenia. Activities of daily living of the patients were assessed (including ADL and IADL) . Comorbidity of the patients was evaluated by the Charlson comorbidity index (CCI). Long-term medication use of the patients was recorded to assesse whether there was polypharmacy. The nutritional status of the patients was examined by the mini nutritional assessment-short form (MNA-SF). The full tandem stance time of the patients was evaluated. The history of falls over the previous year, urinary incontinence, and living conditions of the patients were also recorded. Multivariate logistic regression was used to analyze the related factors for sarcopenia of elderly patients with coronary heart disease. Results: A total of 364 patients were enrolled in the study. The patients were aged 65-96 (74.6±6.5) years and there were 218 (59.9%) male patients. There were 264 cases of stable coronary heart disease and 100 cases of acute coronary syndrome. The median number of long-term used medication was 7. One hundred and fifty-two (41.8%) patients were complicated with type 2 diabetes, 38 (10.4%) patients were complicated with anxiety/depression, and 98 (26.9%) patients had the history of falls over the previous year. Eighty-two (22.5%) patients were complicated with urinary incontinence, 12 patients (3.3%) were complicated with malnutrition and 33 patients (9.2%) were living alone. There were 81 (22.3%) sarcopenic patients and 283 (77.7%) non-sarcopenic patients among all the hospitalized elderly patients with coronary heart disease. The sarcopenic patients were more older, with lower body mass index(BMI)(both P<0.001), higher CCI and more long-term used medication (both P<0.05), higher proportions of malnutrition, urinary incontinence, history of falls, and living alone (all P<0.05) compared to non-sarcopenic patients. ADL and IADL scores of sarcopenic patients were significantly lower than those of non-sarcopenic patients (both P<0.001). There was also a higher proportion of unable to accomplish full tandem stance among sarcopenic patients compared to non-sarcopenic patients (P<0.001). Moreover, higher hs-CRP level (P=0.047) , lower albumin level (P=0.004) and significantly lower prealbumin level (P<0.001) were observed in sarcopenic patients compared to non-sarcopenic patients. Stepwise multivariate binomial logistic regression analysis revealed that male (OR=5.036, 95%CI 1.782-14.230, P=0.002), low BMI (OR=0.883, 95%CI 0.796-0.980, P=0.019), as well as low prealbumin level (OR=0.990, 95%CI 0.980-1.000, P=0.045) were related factors for sarcopenia among elderly patients with coronary heart disease. Conclusions: Sarcopenia is a geriatric condition commonly seen in hospitalized elderly patients with coronary heart disease. Male, low BMI, and low prealbumin level were the factors related to sarcopenia for older adults with coronary heart disease.

Abstract
OBJECTIVE This study aimed to investigate expressions and clinical significance of IL-17 and TNF-α after surgery in patients with Hashimoto's disease (HD) combined with thyroid cancer (TC). PATIENTS AND METHODS From June 2010 to October 2012, 38 patients with HD combined with TC admitted to the oncology department of Tongji Hospital were selected as an experimental group, including three males and 35 females, aged 24-78 years. Forty adults undergoing physical examination during the same period were selected as a control group. All patients in the experimental group were given total endoscopic TC resection. Real-time fluorescence quantification (qRT-PCR) and enzyme-linked immunosorbent assay (ELISA) were used to detect the expression levels of serum IL-17 and TNF-α before and 14 days after surgery. Patients with HD combined with TC were divided into high and low expression groups according to the median values of preoperative IL-17 mRNA and TNF-α mRNA. The relationship between IL-17, TNF-α, and prognosis of patients was analyzed through K-M survival curve. RESULTS The concentrations of IL-17 and TNF-α in serum were also higher than those in control group 14 days after surgery (p < 0.05). qRT-PCT showed that the relative expressions of IL-17 and TNF-α in serum 14 days after surgery were higher than those in control group (p < 0.05). According to the relative expression median of mRNA in IL-17 and TNF-α before surgery, they were divided into high and low expression groups. It was found that the survival rate of high expression groups of IL-17 and TNF-α was lower than that of low expression groups (IL-17, p = 0.028; TNF-α, p = 0.014). CONCLUSIONS The protein and mRNA of IL-17 and TNF-α in serum of HD patients with TC are higher than those of healthy control group. Expressions of IL-17 and TNF-α can be reduced by surgical resection of focal tissue. IL-17 and TNF-α may be used as potential prognostic indicators of HD patients with TC.

Abstract
OBJECTIVE This study aimed to explore the measures of damage control theory (DCT) in the treatment of multiple trauma mainly represented by emergency abdominal trauma. PATIENTS AND METHODS A total of 76 patients with severe multiple trauma in the Yiwu Central Hospital were selected. Among them, 37 patients with severe multiple trauma were treated with DCT (DCT group), and 39 patients were treated with traditional methods (control group). The prothrombin time (PT), the inflammation index, the duration of mechanical ventilation, the length of stay in the Intensive Care Unit (ICU), and the incidence of sepsis were compared between the two groups. RESULTS A total of 60 cases (78.95%) were cured and discharged, and 4 cases (10.81%) died in the DCT group, while 12 cases (30.77%) died in the control group. There were 6 cases (16.22%) of sepsis in the DCT group and 15 cases (38.46%) of sepsis in the control group. This indicates that the mortality and the incidence of sepsis in the DCT group were lower than those in the control group (p<0.05 in all comparisons). The PT activated partial thromboplastin time (APTT), the length of stay in the ICU, and mechanical ventilation in the DCT group were notably shorter than those in the control group. The levels of serum tumor necrosis factor-alpha (TNF-α), Interleukin-6 (IL-6), C-reactive protein (CRP), and IL-10 went up remarkably in both groups (p<0.05), but the levels of serum TNF-α, IL-6, and CRP in the DCT group were lower than those in the control group, while the IL-10 level in the former was significantly higher than that in the latter (p<0.05). CONCLUSIONS It is feasible to apply DCT to rescue patients with multiple trauma, which can effectively reduce the mortality and complications, and shorten the length of stay in the ICU.

Abstract
Objective: To investigate the prevalence and risk factors of diabetic peripheral neuropathy in type 2 diabetic patients under community management programs. Methods: A cross-sectional study was conducted on T2DM patients in eight communities in Wuhan and Changshu cities. Data would included questionnaire, body measurement, blood testing and clinical examination. The criterion of diabetic peripheral neuropathy was under the combination of symptoms with five physical examinations. Binary logistic regression model was used to analyze the influential factors. Results: The overall prevalence of peripheral neuropathy was 71.2% among the diabetic patients who were managed in primary care health services in the two cities. The binary logistic regression method identified older age (≥60 years, OR=2.39, 95%CI:1.95-2.94), longer diabetic duration (≥10 years, OR=1.25, 95%CI: 1.02-1.54), and worse postprandial glucose control (2 h postprandial plasma glucose >10.0 mmol/L: OR=1.65, 95%CI:1.33-2.04) (all P<0.05) as risk factors for the presence of diabetic peripheral neuropathy, while higher education level was protective factor (compared to patients with education levels of primary school or below, OR=0.52, 95%CI: 0.41-0.66; OR=0.59, 95%CI: 0.44-0.79; OR=0.64, 95%CI: 0.44-0.94 for those with education levels of junior high school, senior high school, and college, respectively). Conclusions: High rates of diabetic peripheral neuropathy among T2DM patients suggested the urgent need for early screening and standardized management at the community levels. It is necessary to promote appropriate screening techniques and methods to identify the peripheral neuropathy, in the primary health service institutions.

Abstract
OBJECTIVE Mammalian target of rapamycin (mTOR) can negatively regulate cell autophagy, while its expression and activity are associated with the pathogenesis of osteosarcoma. MicroRNA 100 (MiR-100) down-regulation is associated with the pathogenesis and chemo-sensitivity of osteosarcoma. Bioinformatics analysis revealed the targeted relationship between miR-100 and the 3'-UTR of mTOR. We investigate the role of miR-100 in affecting mTOR expression, osteosarcoma cell autophagy, and sensitivity to cisplatin. PATIENTS AND METHODS MiR-100, mTOR, and Beclin-1 expressions in osteosarcoma tissue and normal control were compared. The relationship between miR-100 and mTOR was verified by dual luciferase assay. MiR-100, mTOR, and Beclin-1 levels in MG-63 cells and MG-63/DDP cells were tested. Cell apoptosis was determined by using flow cytometry. Cell malignancy was evaluated by colony formation assay. RESULTS MiR-100 and Beclin-1 significantly declined, while mTOR significantly increased in osteosarcoma tissue compared with that of normal tissue (p<0.05). MiR-100 targeting significantly inhibited mTOR expression compared to that of untreated (p<0.05). MiR-100 expression was down-regulated and mTOR level was elevated in MG-63/DDP cells compared with MG-63 cells (p<0.05). MG-63/DDP cells exhibited reduced cell autophagy and apoptosis, and enhanced colony formation induced by DDP. MiR-100 mimic and/or small interfere mTOR (si-mTOR) significantly promoted Beclin-1 expression, cell autophagy, and cell apoptosis, while attenuated colony formation. CONCLUSIONS MiR-100 declined, while mTOR up-regulated in osteosarcoma tissue. MiR-100 up-regulation enhanced cell autophagy and apoptosis induced by cisplatin via targeted inhibiting of mTOR.

Abstract
OBJECTIVE Delay to resective epilepsy surgery results in avoidable disease burden and increased risk of mortality. The objective was to prospectively validate a natural language processing (NLP) application that uses provider notes to assign epilepsy surgery candidacy scores. METHODS The application was trained on notes from (1) patients with a diagnosis of epilepsy and a history of resective epilepsy surgery and (2) patients who were seizure-free without surgery. The testing set included all patients with unknown surgical candidacy status and an upcoming neurology visit. Training and testing sets were updated weekly for 1 year. One- to three-word phrases contained in patients' notes were used as features. Patients prospectively identified by the application as candidates for surgery were manually reviewed by two epileptologists. Performance metrics were defined by comparing NLP-derived surgical candidacy scores with surgical candidacy status from expert chart review. RESULTS The training set was updated weekly and included notes from a mean of 519 ± 67 patients. The area under the receiver operating characteristic curve (AUC) from 10-fold cross-validation was 0.90 ± 0.04 (range = 0.83-0.96) and improved by 0.002 per week (P < .001) as new patients were added to the training set. Of the 6395 patients who visited the neurology clinic, 4211 (67%) were evaluated by the model. The prospective AUC on this test set was 0.79 (95% confidence interval [CI] = 0.62-0.96). Using the optimal surgical candidacy score threshold, sensitivity was 0.80 (95% CI = 0.29-0.99), specificity was 0.77 (95% CI = 0.64-0.88), positive predictive value was 0.25 (95% CI = 0.07-0.52), and negative predictive value was 0.98 (95% CI = 0.87-1.00). The number needed to screen was 5.6. SIGNIFICANCE An electronic health record-integrated NLP application can accurately assign surgical candidacy scores to patients in a clinical setting.

Abstract
Gut microbiota plays important roles in host nutrition, immunity, development and health; therefore, disruption of the gut microbiota is closely associated with development of diseases in the host. In amphibians, metamorphosis is associated not only with extensive changes in the gut microbiota, but also with high mortality. Therefore, we hypothesized that unsuccessful restructuring of the gut microbiota during metamorphosis was an important factor that caused the fatalities. To test this hypothesis, we investigated the gut microbiota of apparently sick and healthy giant spiny frog tadpoles during metamorphosis, using high-throughput sequencing of the 16S rRNA gene. Our results showed that most dominant phyla differed significantly among developmental stages of sick and healthy Paa spinosa tadpoles. The differences in the dominant genera in sick and healthy tadpoles were the highest at the stage of degeneration of cloacal tube (TDCT). After the metamorphosis, the composition of the gut microbiota was more alike between healthy and sick tadpoles at the stage of forelimb emergence than at TDCT. These results imply that failed restructuring of the gut microbiota during metamorphosis caused the death of P. spinosa tadpoles. These results provided an important reference to prevent the high actual of P. spinosa tadpoles during metamorphosis. SIGNIFICANCE AND IMPACT OF THE STUDY: We investigated the gut microbiota of apparently sick and healthy giant spiny frog (Paa spinosa) tadpoles during metamorphosis, using high-throughput sequencing of the 16S rRNA gene. Our results showed that the differences in the dominant genera in sick and healthy tadpoles were the highest at the stage of degeneration of cloacal tube.

Abstract
Objective: To describe baseline characteristics of patients with primary Sjogren's syndrome (pSS) with right heart catheterization (RHC)-confirmed pulmonary arterial hypertension (PAH). Methods: This retrospective study included consecutive patients hospitalized with pSS-PAH from Jan.2013 to June.2019 in Tianjin Medical University General Hospital. All patients fulfilled the 2002 revised criteria for pSS proposed by the American-European Consensus Group. PAH was defined according to RHC-based European Society of Cardiology/European Respiratory Society guidelines. Associated variables were described and analyzed. Predictive factors for achieving treatment goals were explored. Sub-groups(based on Anti-SSB antibody positive/negative) were analyzed. Results: Twenty patients with RHC-confirmed pSS-PAH were included (median age at onset, 54.5 years; median PAH duration, 12 months).PAH was the initial manifestation of pSS in 5 patients(26.3%), and shortness of breath was the most common symptom (17/20,85%). Mean pulmonary arterialpressure (mPAP) was 48(38, 55.75)mmHg, pulmonary vascularresistance (PVR) was 11.23 (6.17,14.69)IU, and mean cardiac index was 2.59(2.04,2.98)L·min(-1)·m(-2) in this group. In addition, right ventricular diameter≤40 mm[P=0.009, HR=5.92, 95%CI(1.55, 22.59)] was predictive factor for achieving the treatment goal. Furthermore, compared with Anti-SSB antibody negative patients, patients with Anti-SSB antibody positive had a higher PVR(IU) [14.1(11.23, 22.63)vs 6.4(6.15, 12.36),P=0.025], a higher mPAP(mmHg)[5(48.5,59)vs 39(32.5,50.75),P=0.013], and a lower cardiac index (L·min(-1)·m(-2)) [2.1(1.6,2.5)vs 2.9(2.56,3.41),P=0.002]. Conclusions: pSS-PAH patients are mainly middle-aged women with the most common symptom shortness of breath. And PAH can be the first manifestation of pSS. More attention should be paid to patients with Anti-La/SSB antibody positive and right ventricular diameter ≤40 mm because of higher mPAP, PVR, worse cardiac function and prognosis.

Abstract
Fracture healing is a well-orchestrated and coordinated process and begins with the inflammatory stage involving the infiltration of immune cells and the release of cytokines, including tumour necrosis factor-alpha (TNF-α), interleukin-6 (IL-6) and interleukin-10 (IL-10). Low-magnitude high-frequency vibration (LMHFV) stimulation is effective in promoting fracture healing. The study hypothesis was that the innate immune response was impaired in osteoporotic fracture and LMHFV could positively modulate it. 9-month-old ovariectomy (OVX)-induced osteoporotic rats were randomised into sham (SHAM), OVX control (OVX), OVX-vibration (OVX-VT) or OVX vibration plus administration of COX-2 specific non-steroid anti-inflammatory drugs (OVX-VT-NSAID). LMHFV (35 Hz, 0.3 g) was given 20 min/d and 5 d/week to the treatment groups. Healing and innate immune response were evaluated by weekly radiographs, endpoint micro-computed tomography (µCT), enzyme-linked immunosorbent assay (ELISA) and histomorphometry at weeks 1, 2, 4 and 8 post-treatment. Results showed that OVX slightly elevated systemic inflammation but impaired the innate immune response locally at the fracture site, with significantly lower expressions of TNF-α and IL-6 but higher IL-10 expression during the early stage of healing. LMHFV was effective in accelerating the delayed fracture healing in OVX bones by partly restoring the impaired innate immune response at the fracture site, accompanied by promoted progression of macrophage polarisation from M1 (pro-inflammatory) to M2 (anti-inflammatory) phenotype. In conclusion, vibration treatment could positively modulate the impaired innate immune response and promote macrophage polarisation in osteoporotic-fracture healing.

Abstract
OBJECTIVE To investigate the potential role of Long non-coding RNA (lncRNA) FER1L4 in the diagnosis and prognostic assessment of osteosarcoma. PATIENTS AND METHODS LncRNA FER1L4 expression in osteosarcoma samples was detected by real-time PCR. The Kaplan-Meier method was used to analyze the relationship between lncRNA FER1L4 expression and the survival time of patients. RESULTS LncRNA FER1L4 expression was decreased in osteosarcoma samples. LncRNA FER1L4 was not related to the gender and age of patients, but was significantly associated with disease stage, metastasis, and tumor differentiation. CONCLUSIONS Low-expression of lncRNA FER1L4 might be a prognostic marker in osteosarcoma.

Abstract
OBJECTIVE To investigate the effects and related mechanisms of miR-204 on fracture healing. MATERIALS AND METHODS Mouse osteoblastic cell line MC3T3-E1 was used in our experiment. Three groups were established to investigate the potential function between miR-204 and osteoblastic cells: miR-NC group (negative control), miR-204 mimics group (MC3T3-E1 cells transfected with miR-204 mimics) and miR-204 mimics + inhibitor group (MC3T3-E1 cells transfected with miR-204 mimics and inhibitor). After incubation, cell viability, activity of caspase-3, and migration ability of MC3T3-E1 cells, were measured. Further, the expression levels of Runt-related transcription factor 2 (RUNX2) and Osterix (OSX) were detected and analyzed. RESULTS Compared with miR-NC group, the cell viability and migration ability of MC3T3-E1 cells were enhanced while the activity of caspase-3 was respectively mitigated. Besides, the expression level of RUNX2 and OSX was increased by treatment of miR-204 mimics. However, these variations of the indicators were reversed by the intervention using miR-204 inhibitor. CONCLUSIONS We revealed the promotion effect of miR-204 on fracture healing, indicating that miR-204 could be a potential therapeutic target for the treatment of a fracture.

Abstract
An improved tube etching method to fabricate high-quality fiber probes for optical tweezers by reserving a certain length of bare fiber to form a T-type composite structure was proposed and implemented. This method can overcome the impact of fiber types on the quality of probes in the conventional tube etching effectively. Based on the influence of gravity and diffusion on the motion of reactants, the analysis of formation mechanism was proposed for this method. This procedure retained the advantage of smooth surface in traditional tube etching but shortened the etching time. Our results also demonstrated that light transmittance of the probe fabricated by this method was improved by 6.8 times, resulting in a greater force in cells trapping. This work provided a way of designing and fabricating optical fiber tweezers with a high trapping efficiency.

Abstract
Objective: To summarize the clinical data of diffuse large B-cell lymphoma (DLBCL) in children and to evaluate the efficacy of Beijing Children's Hospital B cell lymphoma protocol in the treatment of pediatric DLBCL. Methods: The data (clinical, pathology, lab and image data) of 46 pediatric DLBCL admitted to the treatment group of Beijing Children's Hospital from January 2005 to June 2017 were collected and analyzed retrospectively. According to the risk factors of staging, existence of poor prognosis genes and giant tumors, stratified treatment was carried out according to the international standard modified LMB89 regimen with high dose and short course. The Kaplan-Meier method was used to calculate the event free survival (EFS) and the overall survival (OS). Results: (1) Among the 46 cases, there were 33 males and 13 females. The median age was 8.0 years. The time from the initial symptom onset to the diagnosis was more than 15 days in 45 children. Fourteen cases had B group symptoms (fever, night sweat, and weight lost), 25 cases had extranodal disease, 39 cases were stage Ⅲ and Ⅳ, 12 cases had bone marrow involvement, 3 cases had jawbone involvement. Thirty cases were group B and 16 cases were group C in the treatment group. (2) Initial symptoms: 6 cases had cervical mass, 20 cases had abdominal mass, 10 had abdominal pain with acute abdomen, 8 cases had fever, 2 cases had snore or upper respiratory tract obstruction. (3) Pathology result: 40 cases were germinal center B cell DLBCL, 6 cases were non germinal center B cell DLBCL, no case had the MYC gene rupture, double hit lymphoma and triple hit lymphoma. (4) Complication and evaluation: the tumor lysis syndrome was seen in 3 cases initially, severe infection and delayed treatment was seen in 1 case, no treatment related death. The first evaluation showed all cases were sensitive to chemotherapy (shrink>25%), the second evaluation showed 1 case had residual disease, the others were complete remission. (5) Treatment and outcome: the 5 year-EFS was the same with 5 year-OS, both were (97.8±2.2) %. Two cases relapsed after treatment off, early relapse was seen in 1 case, and died because of abandoning treatment. Late relapse was seen in 1 case and got a complete remission after Rituximab+group C protocol treatment. Conclusions: Pediatric DLBCL was common in school aged boys, most cases were at middle and late stage at the time of diagnosis. DLBCL had a good prognosis after the treatment with Beijing Children's Hospital's B cell lymphoma protocol, but late relapse could be seen.

Abstract
BACKGROUND AND PURPOSE The residual blood flow artifact is a critical confounder for MR black-blood thrombus imaging of cerebral venous sinus thrombosis. This study aimed to conduct a validation of a new MR black-blood thrombus imaging technique with enhanced blood signal suppression. MATERIALS AND METHODS Twenty-six participants (13 volunteers and 13 patients) underwent conventional imaging methods followed by 2 randomized black-blood thrombus imaging scans, with a preoptimized delay alternating with nutation for tailored excitation (DANTE) preparation switched on and off, respectively. The signal intensity of residual blood, thrombus, brain parenchyma, normal lumen, and noise on black-blood thrombus images were measured. The thrombus volume, SNR of residual blood, and contrast-to-noise ratio for residual blood versus normal lumen, thrombus versus residual blood, and brain parenchyma versus normal lumen were compared between the 2 black-blood thrombus imaging techniques. Segmental diagnosis of venous sinus thrombosis was evaluated for each black-blood thrombus imaging technique using a combination of conventional imaging techniques as a reference. RESULTS In the volunteer group, the SNR of residual blood (11.3 ± 2.9 versus 54.0 ± 23.4, P < .001) and residual blood-to-normal lumen contrast-to-noise ratio (7.5 ± 3.4 versus 49.2 ± 23.3, P < .001) were significantly reduced using the DANTE preparation. In the patient group, the SNR of residual blood (16.4 ± 8.0 versus 75.0 ± 35.1, P = .002) and residual blood-to-normal lumen contrast-to-noise ratio (12.4 ± 7.8 versus 68.8 ± 35.4, P = .002) were also significantly lower on DANTE-prepared black-blood thrombus imaging. The new black-blood thrombus imaging technique provided higher thrombus-to-residual blood contrast-to-noise ratio, significantly lower thrombus volume, and substantially improved diagnostic specificity and agreement with conventional imaging methods. CONCLUSIONS DANTE-prepared black-blood thrombus imaging is a reliable MR imaging technique for diagnosing cerebral venous sinus thrombosis.

Abstract
Purpose: Examine the impact of traumatic brain injury (TBI) on parenting behavior over time. Method: Included 206 children (3-7 years old) with moderate to severe TBI or orthopedic injury, using a prospective longitudinal cohort study design. Assessments completed at baseline, 6-months, 12-months, 18-months, 3.5 years, and 6.8 years after injury. Dependent variables included authoritative, permissive, and authoritarian parenting. Results: Injury characteristics had limited impact on parenting behaviors over time. Levels of authoritative parenting remained stable over time; however, levels of warmth and involvement declined over time for those with TBI. Levels of permissive and authoritarian parenting declined for all participants by 3.5 years post injury. SES and stressors impacted parenting behaviors. Conclusions: While there was limited effect of TBI on parenting behavior over time, it remains unclear how individuals respond to these parenting behaviors years after injury. Clinicians should monitor family and parenting behaviors to foster an environment to promote positive recovery.

Abstract
Carrier transport in AlGaN-based deep ultraviolet (DUV) light emitting diodes (LEDs) with the wavelength of 273 nm has been investigated by introducing polarization modulated electron blocking layer (EBL) that adopts an Al composition and thickness graded multiple quantum barriers (MQB) structure. The experimental result shows that the maximum light output power and external quantum efficiency for the proposed structure at the current of 250 mA are 9.6 mW and 1.03% respectively, severally increasing by 405% and 249% compared to traditional one, meanwhile, the efficiency droop at 250 mA is also dramatically reduced from 42.2% to 16.6%. Further simulation analysis indicates that this graded MQB-EBL enhances the potential barrier height for electrons and meanwhile reduces that for holes, hence effectively suppresses the electron leakage, and at the same time significantly improves the hole injection efficiency. As a result, the whole performance of the LED with the proposed MQB-EBL is dramatically improved.

Abstract
Objective: To investigate the effect of global end-diastolic volume index (GEDI)-guided fluid resuscitation on the prognosis of patients with chronic heart failure and septic shock. Methods: This study was a prospective randomized controlled study. Consecutive eligible patients were divided into 2 groups according to the random number table method: control group (n=21) and experimental group (n=20). On the basis of routine treatment, patients in the control group received early goal-directed therapy until the central venous pressure (CVP) reaching 8-12 mmHg (1 mmHg=0.133 kPa), mean arterial pressure reaching over 65 mmHg, urine volume reaching over 0.5 ml·kg(-1)·h(-1), and central venous oxygen saturation reaching more than 70%. On the basis of routine treatment, patients in the experimental group were monitored continuously on cardiac output with pulse indication and fluid resuscitation guided by volume index GEDI. The GEDI should be maintained on the range of 680-800 ml/m(2). The remaining resuscitation goals were the same as control group. General clinical data of the two groups were collected at admission. Negative fluid balance onset time, duration of mechanical ventilation, ICU mortality and 28-day mortality were compared between the two groups. The outcomes were recorded as listed: start time of negative fluid balance, duration of mechanical ventilation, mortality in ICU and 28-day mortality. Results: There was no significant difference in age, sex, weight, APACHE Ⅱ score, SOFA score and NYHA functional class score between the two groups (all P>0.05). The negative liquid balance onset time in the control group was 3.5 (2.5, 4.0) days, which was significantly longer than that in the experimental group (2.6 (2.0, 3.0) days,U=115.0, P=0.012). The duration of mechanical ventilation was 355 (118, 552) hours in the control group, which was significantly longer than that in the experimental group (132 (36.75, 233.3) hours, U=130, P=0.038). The ICU mortality was 38.1% (8/21) in the control group, tended to be higher than that in the experimental group (20.0%(4/20), χ(2)=1.620, P=0.203). The 28-day mortality was 42.9% (9/21) in the control group, similar as in the experimental group (25.0%(5/20), χ(2)=1.482,P=0.477). Conclusion: Fluid resuscitation guided by volume index (GEDI) may improve the prognosis of patients with chronic heart failure complicated with septic shock.

Abstract
Objective To determine the stability and influence of adherence barriers on medication adherence and seizure control in pediatric epilepsy. Methods Caregivers of 118 children aged 2-12 years old with epilepsy completed the Pediatric Epilepsy Medication Self-Management Questionnaire at nine time points over 2 years post diagnosis. Electronically monitored antiepileptic drug adherence and seizure outcome data were collected. Results Hierarchical linear modeling results for overall barriers remained stable over 2 years. Specific item-level barriers were also generally stable over time, with the exception of running out of medication becoming more of a barrier over time. No specific barriers were related to seizure control; however, difficulties swallowing medication, forgetting, and medication refusal were related to electronically monitored adherence over time. Conclusions Assessing for specific adherence barriers over time may lead to identification of interventions that result in improved adherence and care.

Abstract
Objective: To investigate histopathological characteristics, and differential diagnoses of childhood synovial sarcoma. Methods: HE staining, immunohistochemical staining and fusion gene detection by FISH were performed in 12 cases of synovial sarcoma in childhood at Beijing Children's Hospital from 2016 to 2018. Results: There were 6 cases of biphasic type, 1 case of monophasic epithelial type, 3 cases of monophasic spindle cell type and 2 cases of poorly differentiated synovial sarcomas. EMA, CKpan, bcl-2, CD99, TLE1 and CD34 immunostain positivities were observed in 10/12, 9/12, 12/12, 10/12, 10/12 and 0/12 cases respectively. Unique INI1 immunohistochemical staining was observed in 9/12 cases. SS18-SSX gene fusion was detected in 8 of 11 cases by FISH. Conclusions: Synovial sarcoma is rare in children. Histological morphology combined with immunohistochemistry and FISH SS18-SSX fusion gene detection are important for the diagnosis and differential diagnosis of synovial sarcoma in children.

Abstract
BACKGROUND Last-minute surgery cancellation represents a major wastage of resources and can cause significant inconvenience to patients. Our objectives in this study were: 1) To develop predictive models of last-minute surgery cancellation, utilizing machine learning technologies, from patient-specific and contextual data from two distinct pediatric surgical sites of a single institution; and 2) to identify specific key predictors that impact children's risk of day-of-surgery cancellation. METHODS AND FINDINGS We extracted five-year datasets (2012-2017) from the Electronic Health Record at Cincinnati Children's Hospital Medical Center. By leveraging patient-specific information and contextual data, machine learning classifiers were developed to predict all patient-related cancellations and the most frequent four cancellation causes individually (patient illness, "no show," NPO violation and refusal to undergo surgery by either patient or family). Model performance was evaluated by the area under the receiver operating characteristic curve (AUC) using ten-fold cross-validation. The best performance for predicting all-cause surgery cancellation was generated by gradient-boosted logistic regression models, with AUC 0.781 (95% CI: [0.764,0.797]) and 0.740 (95% CI: [0.726,0.771]) for the two campuses. Of the four most frequent individual causes of cancellation, "no show" and NPO violation were predicted better than patient illness or patient/family refusal. Models showed good cross-campus generalizability (AUC: 0.725/0.735, when training on one site and testing on the other). To synthesize a human-oriented conceptualization of pediatric surgery cancellation, an iterative step-forward approach was applied to identify key predictors which may inform the design of future preventive interventions. CONCLUSIONS Our study demonstrated the capacity of machine learning models for predicting pediatric patients at risk of last-minute surgery cancellation and providing useful insight into root causes of cancellation. The approach offers the promise of targeted interventions to significantly decrease both healthcare costs and also families' negative experiences.

Abstract
A survey was conducted to analyze the HIV testing status and related influencing factors of male sexually transmitted diseases(STD) patients attending 18 county-level hospitals in Shandong Province from July 2015 to August 2016. The HIV detection rate of 1 570 subjects was 77.58% (1 218/1 570), and the HIV-antibody positive rate was 0.99% (12/1 218). Compared with general hospitals patients, urinary and anorectal patients, non-sexual patients, and patients with negative attitudes toward HIV testing, patients were more likely to be tested for HIV from specialized hospitals (OR=3.74, 95%CI:2.53-5.54), the skin and venereal section (OR=1.92, 95%CI: 1.31-2.79), the STD group (OR=2.02, 95%CI: 1.34-3.03) and patients with positive attitude (OR=15.20, 95%CI:10.74-21.52).

Abstract
Objective: To investigate the food source of water of college students from Hebei Province in spring. Methods: In March 2017, the subjects were recruited in a college in Baoding, Hebei Province. 156 students completed the investigation. All foods were collected for 3 consecutive days using duplicate portion study combined with weighing method to test the water content of various foods. To analyze the water content of the food and calculate the proportion to the total amount of food water intake, the edible parts of each meal were divided into staple food, dishes, porridge, soup and snacks. Body mass index (BMI) was grouped according to quartiles, and the differences in food intake and food water sources among subjects of different genders and BMI were compared. Results: The age of subjects was (19.8±1.1) years old, including 80 male students. The median intake of staple food, dishes, porridge, soup and snacks per day was 562 g, 743 g, 111 g, 102 g and 0 g, respectively. The median intake of water from staple food, dishes, porridge, soup and snacks per day was 301 ml/d, 620 ml/d, 97 ml/d, 93 ml/d and 0 ml/d, respectively. The median ratio of water intake to total food water intake of staple food, dishes, porridge, soup and snacks was 27%, 53%, 8%, 8% and 0%, respectively. The median intake of water from staple food and dishes in male students was significantly higher than that of female students (P<0.05). The amount of water intake from porridge of female students was significantly higher than that of male students (P<0.05). There was no significant difference in the water intake from soup and snacks between different genders. There was no significant difference in food intake and food water sources among college students with different BMI (P>0.05). Conclusion: The food source of water of college students from Hebei Province in spring is mainly based on dishes and staple foods. The food source of water for boys and girls is different.

Abstract
At present, methods of water-intake survey include government, industry, sector statistics data, dietary survey (24 hours dietary recall, dietary record and food frequency questionnaire), fluid intake survey (retrospective fluid-intake questionnaire, 1-5 days 24 hours fluid-intake survey, 7 days 24 hours fluid-intake record), weighing method with the food composition table, weighing method, duplicate portion method and chemical analysis, and so on. The method of 7 days 24 hours fluid-intake record is an internationally recognized and authoritative method for fluid-intake survey with the highest accuracy, which can reflect the differences of fluid intake between working and non-working days, and can obtain detailed data on behaviors and patterns of fluid water, such as the time, types and places of fluid intake. The method of combining weighing method, duplicate portion method and chemical analysis is used to analyze water intake from food with the highest accuracy, which can be used in an extensive range of population and areas, but with high cost and complex operating steps. It is of great practical significance to compare and evaluate the advantages and disadvantages of different methods about water-intake survey, which will be helpful for researchers to choose appropriate methods for water-intake survey to obtain accurate and representative data in various areas, different population, and complex circumstances.

Abstract
Objective: To investigate the effects of different expression of monoacylglycerol lipase (MAGL) in tumor-associated macrophages (TAMs) with the proliferation of MHCC97H human liver cancer cells in vivo and its mechanism. Methods: Human peripheral blood-derived monocyte was induced to differentiate into M2-type TAMs and was identified by flow cytometry. The co-culture model of TAMs and MHCC97H human liver cancer cells was established, and the expression of MAGL in TAMs cells was detected by qRT-PCR. The expression of MAGL in TAMs cells was detected by plasmid transfection. ELISA and qRT-PCR was used to detect the mRNA expression levels and secretion levels of inflammatory factors in TAMs cells. The subcutaneous tumor model of MHCC97H mice was constructed to observe the effect of different expression of MAGL in TAMs cells with the proliferation of MHCC97H human liver cancer cells in vivo. F-test was used for the measurement of homogeneity of variance between two independent samples. A t-test was used for homogeneity of variance, and the corrected t-test was used for non-homogeneity of variance. Results: Human peripheral blood-derived monocytes were successfully induced to differentiate into M2-type TAMs. An in vitro co-culture model was established. qRT-PCR showed that MHCC97H human liver cancer cells significantly down-regulated the expressional level of MAGL in TAMs cells. The constructed subcutaneous tumor model of mice demonstrated that up-regulation up-regulation of MAGL expression in M2-type TAMs inhibited the proliferation of MHCC97H human liver cancer cells in vivo. Furthermore, the mechanistic study illustrated that the high expression of MAGL promoted the transcription and secretion of inflammatory factors such as interleukin-1 beta, interleukin-6 and tumor necrosis factor-alpha in M2-type TAMs cells. Conclusion: The overexpression of MAGL inhibits the proliferation of MHCC97H hepatocellular carcinoma cells in vivo, and its mechanism may be associated to the release of inflammatory factors that from TAMs cells.

Abstract
At present, there is no accurate and effective method for treating neoplastic pericardial effusion. This study analyzed the current literature on the treatment of neoplastic pericardial effusion to provide advice and guidance for clinical treatment. Surgical treatments include pericardial puncture, extension of catheter drainage, pericardial window, and surgical pericardiotomy. Each surgical procedure has a corresponding indication, and the best treatment is selected according to the patient's specific conditions. Systemic chemotherapy is effective in lymphoma and small cell lung cancer that are sensitive to chemotherapeutic drugs. Although pericardial injection of drugs is effective for pericardial tamponade and recurrent pericardial effusion, these methods can only temporarily relieve symptoms and cannot prolong the life of patients. In recent years, immunotherapy, especially adoptive immunotherapy, has achieved good results in the treatment of neoplastic pericardial effusion, thus providing a novel treatment option for neoplastic pericardial effusion.

Abstract
BACKGROUND The pediatric emergency department (PED) provides care for adolescents at high risk of unintended pregnancy, but little is known regarding the efficacy of PED-based pregnancy prevention interventions. The objectives of this PED-based pilot intervention study were to 1) assess the rate of contraception initiation after contraceptive counseling and appointment facilitation in the PED during the study period, 2) identify barriers to successful contraception initiation, and 3) determine adolescent acceptability of the intervention. METHODS This pilot intervention study included females 14 to 19 years of age at risk for unintended pregnancy. Participants received standardized contraceptive counseling and were offered an appointment with gynecology. Participants were followed via electronic medical record and phone to assess contraception initiation and barriers. Chi-square tests were used to examine the association between contraception initiation and participant characteristics. RESULTS A total of 144 patients were eligible, and 100 were enrolled. In the PED, 68% (68/100) expressed interest in initiating hormonal contraception, with 70% (48/68) of interested participants indicating that long-acting reversible contraception (LARC) was their preferred method. Twenty-five percent (25/100) of participants initiated contraception during the study period, with 19 participants starting LARC. Thirty-nine percent (22/57) of participants who accepted a gynecology appointment attended that appointment. Barriers to follow-up include transportation and inconvenient follow-up times. Participants were accepting of the intervention with 93% agreeing that the PED is an appropriate place for contraceptive counseling. CONCLUSIONS PED contraceptive counseling is acceptable among adolescents and led to successful contraception initiation in 25% of participants. The main barrier to contraception initiation was participant follow-up with the gynecology appointment.

Abstract
BACKGROUND AND PURPOSE The cerebellum plays an important role in motor and cognitive functions. However, whether and how the normal-appearing cerebellum is impaired in patients with neuromyelitis optica spectrum disorders remain unknown. We aimed to identify the occult structural damage of the cerebellum in neuromyelitis optica spectrum disorder and its possible causes at the level of substructures. MATERIALS AND METHODS Normal-appearing gray matter volume of the cerebellar lobules and nuclei and normal-appearing white matter volume of the cerebellar peduncles were compared between patients with neuromyelitis optica spectrum disorder and healthy controls. RESULTS The cerebellar damage of patients with neuromyelitis optica spectrum disorder in the hemispheric lobule VI, vermis lobule VI, and all cerebellar nuclei and peduncles was related only to spinal lesions; and cerebellar damage in the hemispheric lobules VIII and X was related only to the aquaporin-4 antibody. The mixed cerebellar damage in the hemispheric lobules V and IX and vermis lobule Crus I was related mainly to spinal lesions; and mixed cerebellar damage in the hemispheric lobule VIIb was related mainly to the aquaporin-4 antibody. Other cerebellar substructures showed no significant cerebellar damage. CONCLUSIONS We have shown that the damage in cerebellar normal-appearing white matter and normal-appearing gray matter is associated with aquaporin-4-mediated primary damage or axonal degeneration secondary to spinal lesions or both. The etiologic classifications of substructure-specific occult cerebellar damage may facilitate developing neuroimaging markers for assessing the severity and the results of therapy of neuromyelitis optica spectrum disorder occult cerebellar damage.

Abstract
BACKGROUND Surgery is becoming more practical and effective than conservative treatment in improving the poor outcomes of patients with breast cancer liver metastasis (BCLM). However, there is no generally acknowledged set of standards for identifying BCLM candidates who will benefit from surgery. METHODS Between January 2011 and September 2018, 67 female BCLM patients who underwent partial hepatectomy were selected for analysis in the present study. Prognostic factors after hepatectomy were determined. Univariate and multivariate analyses were performed to identify predictors of overall survival (OS) and intrahepatic recurrence-free survival (IHRFS). RESULTS The 1-, 3- and 5-year OS of patients treated with surgery was 93.5%, 73.7% and 32.2%, respectively, with a median survival time of 57.59 months. The Pringle manoeuvre [hazard radio (HR) = 0.117, 95% CI0.015-0.942, p = 0.044] and an increased interval between breast surgery and BCLM diagnosis (HR0.178, 95% CI 0.037-0.869, p = 0.033) independently predicted improved overall survival for BCLM patients. The 1-, 2- and 3-year IHRFS of patients who underwent surgery was 62.8, 32.6% and 10.9%, respectively, with a median intrahepatic recurrence-free survival time of 13.47 months. Moderately differentiated tumours (HR 0.259, 95% CI 0.078-0.857, p = 0.027) and the development of liver metastasis more than 2 years after breast surgery (HR 0.270, 95% CI 0.108-0.675, p = 0.005) might be predictors of increased IHRFS. CONCLUSIONS An interval of more than 2 years between breast cancer surgery and liver metastasis seems to be an indication of liver surgery in BCLM patients. The Pringle manoeuvre and moderately differentiated tumours are potential predictors associated with OS and IHRFS, respectively, as benefits from liver resection. Studies with increased sample sizes are warranted to validate our results.
