Abstract
Large cell neuroendocrine carcinoma (LCNEC) is a rare and highly invasive lung cancer subtype with an overall poor prognosis. Due to its low incidence rate and unusual pathological features, the clinical management of LCNEC remains controversial. The present study aimed to assess the effect of immune checkpoint inhibitors (ICIs) on treatment response and survival outcomes in patients with advanced LCNEC. The clinical data from 148 patients with LCNEC treated with ICIs at The First Affiliated Hospital of Zhengzhou University (Zhengzhou, China) between January 2019 and September 2021 were retrospectively analyzed. Kaplan-Meier and multivariable Cox regression analyses were used to evaluate associations between clinicopathological variables and patient outcomes. Patients treated with ICIs demonstrated extended median overall survival (mOS) times [23.5 months; 95% confidence interval (CI), 18.524-28.476] compared with patients who did not receive ICIs (11.2 months; 95% CI, 4.530-18.930) (P<0.001). Univariate analysis revealed that histological subtype (P=0.043), lymph node metastases (P=0.032) and number of metastatic organs (P=0.009) were associated with a poor prognosis. The heterogeneity of pathological components was associated with prognosis, and the mOS time was shorter for mixed LCNEC than that for pure LCNEC (P=0.043). The median progression-free survival (mPFS) (9.78 vs. 9.37 months; P=0.82) and mOS (20.70 vs. 25.79 months; P=0.181) times showed no significant association with regard to different regimens of immuno-based combination therapy (chemotherapy combined with ICIs vs. anti-angiogenic agents combined with ICIs). Poor Eastern Cooperative Oncology Group performance status score (P=0.04), multiple organ metastases (P=0.02) and high cancer antigen 125 levels (P=0.01) were independent risk factors of a poor prognosis. The present findings offer valuable insights into potential prognostic markers and highlight the favorable impact of ICIs on OS in advanced LCNEC. Prospective clinical studies are required to validate the therapeutic value of ICIs in LCNEC.

Abstract
BACKGROUND The impact of immune checkpoint inhibitors (ICIs) based treatments on non-small cell lung cancers (NSCLCs) with RET fusions remains poorly understood. METHODS We screened patients with RET fusions at the First Affiliated Hospital of Zhengzhou University and included those who were treated with ICIs based regimens for further analysis. We evaluated clinical indicators including objective response rate (ORR), disease control rate (DCR), progression-free survival (PFS), and overall survival (OS). RESULTS A total of 232 patients with RET fusions were included in the study. Of these, 129 patients had their programmed death-ligand 1 (PDL1) expression levels tested, with 22 patients (17.8%) having a PDL1 level greater than or equal to 50%. Additionally, tumor mutational burden (TMB) status was evaluated in 35 patients, with the majority (30/35, 85.8%) having a TMB of less than 10 mutations per megabase. Out of the 38 patients treated with ICI based regimens, the median PFS was 5 months (95% confidence interval [CI]: 2.4-7.6 months) and the median OS was 19 months (95% CI: 9.7-28.3 months) at the time of data analysis. Stratification based on treatment lines did not show any significant differences in OS (18 vs. 19 months, p = 0.63) and PFS (6 vs. 5 months, p = 0.86). The ORR for patients treated with ICIs was 26.3%. Furthermore, no significant differences were found for PFS (p = 0.27) and OS (p = 0.75) between patients with positive and negative PDL1 expression. Additionally, there was no significant difference in PD-L1 levels (p = 0.10) between patients who achieved objective response and those who did not. CONCLUSIONS Patients with RET fusion positive NSCLCs may not benefit from ICI based regimens and therefore should not be treated with ICIs in clinical practice.

Abstract
PURPOSE/OBJECTIVE(S) To automate the digitization of plastic and titanium applicators used in interstitial and hybrid gynecological (GYN) computed tomography (CT)-based high-dose-rate (HDR) brachytherapy procedures to accelerate the planning and reduce the potential for planning errors. Our hypothesis is that artificial intelligence can accurately automate the identification and digitization of plastic and titanium applicators used in HDR brachytherapy. MATERIALS/METHODS Forty-eight patients who had received GYN procedures (7 tandem/ring: plastic applicators, 41 interstitial: titanium needles) were selected retrospectively. Patients were randomly split into training (n = 40) and test (n = 8) sets for this study. DICOM images and digitized needles from delivered plans were converted to 3D binary format. The points from each needle were transformed to individual contours and combined into a single binary mask using custom software. Using nnU-Net, a self-configuring deep convolutional neural network, 2D and 3D U-Net architectures were trained and ensembled. With the CT image as input, the nnU-Net model learned features to automatically segment the needle contours. Lastly, a 3D U-Net model was trained using 5 of the 7 tandem/ring cases (plastic applicators), with two reserved to evaluate this automated digitization. The models' performance was evaluated using the Dice Similarity Coefficient (DSC) and identification rate for individual needles. RESULTS The model trained on 40 patients performed well on titanium needle cases [mean (+/- std. dev.) DSC = 0.738+/-0.034], but did not perform well on the tandem/ring cases [DSC = 0.408] in the test set. This model automatically identified 100% (54 out of 54) titanium needles but missed all plastic applicators from tandem/ring cases. Training a model with only a limited number of tandem/ring (plastic applicators) cases greatly improved segmentation accuracy [mean DSC = 0.646] for tandem/ring test cases. This model which was trained using only tandem/ring cases, automatically identified 7 out of 7 needles (100% vs 0% with previous model) from cases in the test set. CONCLUSION The nnU-Net can automatically detect HDR needles with high confidence. Using applicator-specific identification models may improve digitization accuracy. Further evaluation of these tools on larger datasets will confirm the findings of this study.

Abstract
Background: The deletion of exon 19 and the Leu858Arg mutation of exon 21 are the most frequently observed mutations in the epidermal growth factor receptor (EGFR) gene, and patients with these mutations have shown significant benefits from EGFR-tyrosine kinase inhibitors (TKIs). However, there exists a small subgroup of patients with uncommon/rare mutations of EGFR, including compound mutations, which display a high degree of heterogeneity in terms of clinical features and variable sensitivities to EGFR-TKIs. The understanding of these uncommon mutations and their response to targeted therapy is still unclear and requires further investigation. Case presentation: We presented a case of a never-smoking patient with lung adenocarcinoma and brain metastasis. Initially, she received chemotherapy plus immune checkpoint inhibitor as first-line therapy as no EGFR mutations were detected by amplification-refractory mutation system-polymerase chain reaction. However, disease progressed rapidly. Subsequently, next-generation sequencing was carried out and revealed a rare compound mutation, L833V/H835L, in exon 21 of EGFR. As a result, she was switched to second-line therapy with the third-generation TKI aumolertinib, which demonstrated good efficacy. The patient was evaluated for a remarkable progression-free survival of 18 months and an overall survival of 29 months. Conclusion: The present study supports that aumolertinib might be a good treatment option for advanced NSCLC patients with EGFR L833V/H835L mutation, particularly in patients with brain metastasis. Furthermore, conducting a comprehensive screening for gene mutations is crucial in effectively identifying potential oncogenic driver mutations and guiding mutation-targeted therapy decisions in clinical practice.

Abstract
Using transdimensional plasmonic materials (TDPM) within the framework of fluctuational electrodynamics, we demonstrate nonlocality in dielectric response alters near-field heat transfer at gap sizes on the order of hundreds of nanometers. Our theoretical study reveals that, opposite to the local model prediction, propagating waves can transport energy through the TDPM. However, energy transport by polaritons at shorter separations is reduced due to the metallic response of TDPM stronger than that predicted by the local model. Our experiments conducted for a configuration with a silica sphere and a doped silicon plate coated with an ultrathin layer of platinum as the TDPM show good agreement with the nonlocal near-field radiation theory. Our experimental work in conjunction with the nonlocal theory has important implications in thermophotovoltaic energy conversion, thermal management applications with metal coatings, and quantum-optical structures.

Abstract
Objective Current treatment agents for HCC are mostly immune checkpoint inhibitors (ICIs) plus bevacizumab and multitarget tyrosine kinase inhibitors (TKIs); however, their limited overall response rate and shorter median progression-free survival (PFS) discourage their frequent use. The development of Mesenchymal Epithelial Transition Factor receptor (MET) Tyrosine Kinase Inhibitors (MET-TKI) has transformed the treatment pattern in MET-altered solid tumors and improved their prognosis. However, the benefits of MET-TKIs in MET-amplified hepatocellular carcinoma (HCC) remain unclear. Methods Here, we present a case of advanced HCC amplified with MET treated with savolitinib, a MET-TKI, after progression from first-line treatment with bevacizumab plus sintilimab. Results The patient achieved a partial response (PR) to savolitinib in the second line setting. The progression-free survival (PFS) of first-line of bevacizumab plus sintilimab and sequential second-line treatment with MET-TKI, savolitinib, are 3 and over 8 months, respectively. furthermore, the patient still had continuous PR status with manageable toxicities. Conclusions The present case report provides first-hand evidence that savolitinib may be beneficial for patients with advanced MET-amplified HCC and offers a promising treatment option.

Abstract
Alcohol use disorder (AUD) is characterized by loss of intake control, increased anxiety, and susceptibility to relapse inducing stressors. Both astrocytes and neurons contribute to behavioral and hormonal consequences of chronic intermittent ethanol (CIE) exposure in animal models. Details on how CIE disrupts hypothalamic neuro-glial communication, which mediates stress responses are lacking. We conducted a behavioral battery (grooming, open field, reactivity to a single, uncued foot-shock, intermittent-access two-bottle choice ethanol drinking) followed by Ca2+ imaging in ex-vivo slices of paraventricular nucleus of the hypothalamus (PVN) from male rats exposed to CIE vapor or air-exposed controls. Ca2+ signals were evaluated in response to norepinephrine (NE) with or without selective α-adrenergic receptor (αAR) or GluN2B-containing N-methyl-D-aspartate receptor (NMDAR) antagonists, followed by dexamethasone (DEX) to mock a pharmacological stress response. Expectedly, CIE rats had altered anxiety-like, rearing, grooming, and drinking behaviors. Importantly, NE-mediated reductions in Ca2+ event frequency were blunted in both CIE neurons and astrocytes. Administration of the selective α1AR antagonist, prazosin, reversed this CIE-induced dysfunction in both cell types. Additionally, the pharmacological stress protocol reversed the altered basal Ca2+ signaling profile of CIE astrocytes. Signaling changes in astrocytes in response to NE were correlated with anxiety-like behaviors, such as the grooming:rearing ratio, suggesting tripartite synaptic function plays a role in switching between exploratory and stress-coping behavior. These data show how CIE exposure causes persistent changes to PVN neuro-glial function and provides the groundwork for how these physiological changes manifest in behavioral selection.

Abstract
Abstract
Introduction
Recent clinical trials of heart failure with preserved ejection fraction (HFpEF) have observed varying patient profiles by ejection fraction (EF), with attenuation of treatment benefits as EF increases. In routine clinical practice, the degree to which patients hospitalized for HF with EF≥60% may differ from those with lower EF is unknown.
Purpose
To compare patient characteristics, treatment patterns, and clinical outcomes across the range of EF among patients hospitalized for HFpEF.
Methods
Using the Humedica electronic medical records database between Jan 2010 and Dec 2020, patients hospitalized for a primary diagnosis of HF with EF>40% and who were haemodynamically stable at admission, without concurrent acute coronary syndrome or end-stage renal disease, and treated with intravenous (IV) diuretic agents within 48 h of admission were identified. Patient characteristics, treatment patterns, and clinical outcomes were compared by EF ranges of 41–49%, 50–59%, and ≥60%.
Results
Of 47,026 patients hospitalized with HFpEF, 6,335 (13%) had EF 41–49%, 18,603 (40%) had EF 50–59%, and 22,088 (47%) had EF≥60%. Across all 3 groups, patients were similar with respect to age (median 77 years for each group), race (83–84% White, 12–13% Black), systolic blood pressure (137–138 mmHg at admission), and eGFR (63–64 mL/min/1.73 m2 at admission). With progressively higher EF group, the proportion of women increased (45% vs 54% vs 65%) and median NT-proBNP decreased (4,221 vs 2,945 vs 2,234 pg/mL). Patients with EF ≥60% had the lowest rates of coronary artery disease and atrial fibrillation, and the highest rates of chronic pulmonary disease (Figure 1, Panel A). Discharge medications were generally similar, with exception of less beta-blocker use and more calcium channel blocker use among those with EF ≥60% (Figure 1, Panel B). Discharge use of angiotensin receptor-neprilysin inhibitor and sodium glucose cotransporter-2 inhibitor therapies were each <1% in all groups. Hospital length of stay (median 4 days for each group) and in-hospital mortality (1.1–1.3%) were similar across groups, but rates of in-hospital acute respiratory failure were higher among patients with EF ≥60% (27% vs 230-25% for lower EF groups). Rates of 30-day and 12-month post-discharge clinical events were high irrespective of EF, without meaningful differences between groups (Figure 2).
Conclusion
In a contemporary real-world population of US patients hospitalized for HF with EF >40%, nearly half had an EF≥60%. While clinical profiles and discharge medications varied, post-discharge outcomes were similarly poor irrespective of EF. There remain important opportunities to improve the care and outcomes for patients with HF across the range of preserved ejection fraction.

Abstract
Objective: To describe the clinical characteristics of Mycoplasma pneumoniae infection and analyze the factors associated with co-infections with other pathogens in children, and provide evidence for improvement of community acquired pneumonia (CAP) prevention and control in children. Methods: Based on the surveillance of hospitalized acute respiratory infections cases conducted in Soochow University Affiliated Children's Hospital (SCH), the CAP cases aged <16 years hospitalized in SCH between 2018 and 2021 were screened. The pathogenic test results of the cases were obtained through the laboratory information system, and their basic information, underlying conditions, and clinical characteristics were collected using a standardized questionnaire. The differences in clinical characteristics between M. pneumoniae infection and bacterial or viral infection and the effect of the co-infection of M. pneumoniae with other pathogens on clinical severity in the cases were analyzed; logistic regression was used to analyze the factors associated with the co-infections with other pathogens. Results: A total of 8 274 hospitalized CAP cases met the inclusion criteria. Among them, 2 184 were positive for M. pneumoniae (26.4%). The M. pneumoniae positivity rate increased with age (P<0.001), and it was higher in girls (P<0.001) and in summer and autumn (P<0.001). There were statistically significant differences in the incidence of wheezing, shortness of breath, wheezing sounds and visible lamellar faint shadow on chest radiographs, as well as fever and hospitalization days among M. pneumoniae, bacterial, and viral infection cases (all P<0.05). In the cases aged <60 months years, co-infection cases had higher rates of wheezing, gurgling with sputum and stridor; and in the cases aged ≥60 months, co-infection cases had a higher rate of shortness of breath (all P<0.05). Multifactorial logistic regression analysis showed that being boys (aOR=1.38,95%CI:1.15-1.67), being aged <6 months (aOR=3.30,95%CI:2.25-4.89), 6-23 months (aOR=3.44,95%CI:2.63-4.51), 24-47 months (aOR=2.50,95%CI:1.90-3.30) and 48-71 months (aOR=1.77,95%CI:1.32-2.37), and history of respiratory infection within 3 months (aOR=1.28,95%CI:1.06-1.55) were factors associated with co-infections of M. pneumoniae with other pathogens. Conclusions: M. pneumoniae was the leading pathogen in children hospitalized due to CAP. M. pneumoniae infections could cause fever for longer days compared with bacterial or viral infections; M. pneumoniae was often co-detected with virus or bacteria. Being boys, being aged <72 months and history of respiratory infection within 3 months were associated factors for co-infections.

Abstract
BACKGROUND Anaplastic lymphoma kinase (ALK) fusion is a prognostic indicator for patients with non-small cell lung cancer (NSCLC) receiving tyrosine kinase inhibitors (TKIs). The real-world data of ALK TKIs remain a major concern. METHODS Patients with ALK-positive advanced NSCLC, who received crizotinib or alectinib treatment in first line, were retrospectively reviewed. ALK status was detected using immunohistochemistry (IHC) or next-generation sequencing (NGS). Clinical outcomes have been comprehensively analyzed between TKIs, ALK fusions, EML4-ALK variants, and next-generation TKIs after crizotinib failure. RESULTS One hundred sixty-eight patients were successively enrolled (crizotinib, n = 109; alctinib, n = 59). Alectinib showed consistent superiority in progressive-free survival (PFS) over crizotinib (hazard ratio [HR]: 0.43, 95% confidential interval [CI]: 0.24-0.77, p = 0.004). Multivariate Cox regression showed chemotherapy (CT) prior to TKIs or synchronous chemotherapy seemed not to improve PFS compared to ALK inhibitors alone (p > 0.05). And, alectinib was superior to crizotinib in prolonging intracranial PFS (HR 0.12, 95% CI: 0.03-0.49, p = 0.003). Patients in EML4 group had a better prognosis than those in non-EML4 group after alectinib administration (HR 0.13, 95% CI: 0.03-0.60, p = 0.009). TP53 co-mutations were relatively common (34.0%) and associated with adverse outcome in ALK-positive patients (adjusted HR 2.22, 95% CI: 1.00-4.92, p = 0.049). After crizotinib failure, 33 patients received a sequential application of next-generation ALK TKIs. Compared to ceritinib and brigatinib, alectinib might have better PFS (p = 0.043). CONCLUSION Our results revealed alectinib had better PFS and higher intracranial efficacy compared to crizotinib in ALK-positive NSCLC, and might improve PFS by comparison with ceritinib and brigatinib after crizotinib failure.

Abstract
V-Raf murine sarcoma viral oncogene homolog B (BRAF) kinase, which was encoded by BRAF gene, plays critical roles in cell signaling, growth, and survival. Mutations in BRAF gene will lead to cancer development and progression. In non-small cell lung cancer (NSCLC), BRAF mutations commonly occur in never-smokers, women, and aggressive histological types and accounts for 1%-2% of adenocarcinoma. Traditional chemotherapy presents limited efficacy in BRAF-mutated NSCLC patients. However, the advent of targeted therapy and immune checkpoint inhibitors (ICIs) have greatly altered the treatment pattern of NSCLC. However, ICI monotherapy presents limited activity in BRAF-mutated patients. Hence, the current standard treatment of choice for advanced NSCLC with BRAF mutations are BRAF-targeted therapy. However, intrinsic or extrinsic mechanisms of resistance to BRAF-directed tyrosine kinase inhibitors (TKIs) can emerge in patients. Hence, there are still some problems facing us regarding BRAF-mutated NSCLC. In this review, we summarized the BRAF mutation types, the diagnostic challenges that BRAF mutations present, the strategies to treatment for BRAF-mutated NSCLC, and resistance mechanisms of BRAF-targeted therapy.

Abstract
OBJECTIVES Quantifying the number of older adults that are food insecure in a specific geographic area is critical in developing and scaling public health prevention and response programs at the local level. However, current estimates of older adult food insecurity only consider financial constraints, following the same methodology as the general population, even though the drivers for older adults are different and multidimensional. This study aims to build a general approach to quantify the food-insecurity among older adults at the local level, using publicly available data that can be easily obtained across the country. METHODS 13 risk factors for food insecurity among older adults were identified leveraging existing studies, following the Social Ecological Model (SEM), and the weighted impact of each factor was determined. Publicly available data sources were identified for each factor, ZIP code level data was compared to national averages, and the weighted data for each factor were aggregated to determine the overall food insecurity at the local level. RESULTS Based on the averaged odds ratios across all the studies, of the 13 risk factors, beyond financial constraints, having a disability was the most impactful factor and distance to the nearest grocery store was the least impactful. A ZIP code level model of Honolulu County was developed as an example to demonstrate the approach, showing that food insecurity among older adults in the county was 2.5 times that which was reported from the Current Population Survey (16.5% versus 6.5%). CONCLUSION This evidence-based model considered factors that impact food insecurity among older adults across all the spheres of the SEM. The drivers of food insecurity among older adults are different than the drivers for the general population, resulting in a higher percentage of older adults being food insecure than currently reported.

Abstract
Accurate reduction is of vital importance in the treatment of zygomaticomaxillary complex (ZMC) fractures. Computer-assisted navigation systems (CANS) have been employed in ZMC fractures to improve the accuracy of surgical reduction. However, randomized controlled trials on this subject are rare and the benefits of CANS remain controversial. The aim of this study was to compare reduction errors between navigation-aided and conventional surgical treatment for ZMC fractures. Thirty-eight patients with unilateral type B ZMC fractures were enrolled. Preoperative computed tomography data were imported into ProPlan software for virtual surgical planning. Open reduction and internal fixation was performed with CANS (experimental group) or without CANS (control group). Postoperative computed tomography scans were obtained to examine the difference between surgical planning and the actual postoperative outcome, namely reduction errors. The median translational reduction errors in the X, Y, and Z axes were 0.80 mm, 0.40 mm, and 0.80 mm, respectively, in the experimental group and 0.53 mm, 0.86 mm, and 0.83 mm, respectively, in the control group (P > 0.05). The median rotational reduction errors in pitch, roll, and yaw were 0.92°, 2.47°, and 1.54°, respectively, in the experimental group and 1.45°, 3.68°, and 0.76°, respectively, in the control group (P > 0.05). In conclusion, compared with conventional reduction surgery, navigation-aided surgery showed no significant improvement in reduction accuracy in the treatment of type B ZMC fractures (Chinese Clinical Trial Registry, registration number ChiCTR1800015559).

Abstract
Background In the existing next generation sequencing (NGS) system, epidermal growth factor receptor (EGFR) exon 19 deletion-insertion (19delins) is still interpreted into the category of EGFR exon 19 deletion (19del). However, the controversy exists whether the two mutation types have the similar responses and resistant mechanisms to first-generation EGFR tyrosine kinase inhibitor (TKI) in non-small cell lung cancer (NSCLC) patients. Methods We successively and retrospectively reviewed the NGS data of 3054 patients diagnosed as advanced NSCLC from November 2017 to September 2020. Finally, 41 patients with EGFR 19delins mutation and 41 patients with EGFR 19del mutation who received first-generation EGFR TKIs as first-line therapy were included in the study. Results A total of 17 genotypes were identified in this study, including L747_P753delinsS (10/41), L747_A750delinsP (9/41), L747_T751delinsP (6/41) and E746_S752delinsV (3/41). Under the same baseline characteristics, the population of EGFR 19delins respond well to first line EGFR TKIs as well as those of EGFR 19del, with little difference in median progression-free survival (mPFS): 10.4 months vs. 13.1 months, p = 0.1076). Interestingly, patients with L747_T751delinsP seem to have a better mPFS than others (18.7 months vs. 13.1 months, p = 0.035). After the disease progression, both EGFR 19delins and EGFR 19del had similar rates of developing EGFR T790M mutation resistance (45.8% vs. 57.8%), and those receiving osimeritinib as second-line treatment obtain the similar survival benefits (mPFS: 12.0 months vs. 12.2 months (p = 0.97). Conclusions This retrospective cohort study furnish the evidence that therapeutic responses and survival of untreated NSCLC population with EGFR 19delins mutation are equal to those with common EGFR 19del mutation after administration of EGFR TKIs therapy.

Abstract
Objective: To investigate the short-term efficacy of anti-IgE monoclonal antibody (Omalizumab) in the treatment of recurrent chronic rhinosinusitis with nasal polyps (CRSwNP) complicated with asthma. Methods: Patients with recurrent CRSwNP and comorbid asthma in Beijing TongRen Hospital from May to December of 2020 were continuously recruited and received a 4-month therapy of stable background treatment plus Omalizumab. Results of visual analog scales (VAS) of nasal symptoms, sino-nasal outcome test-22 (SNOT 22) and nasal polyp scores were collected at baseline and post-treatment (1, 2, 3 and 4 months after treatment). Blood routine tests, total nasal resistances (TNR), minimum cross-sectional areas (MCA), total nasal cavity volumes (NCV), forced expiratory volumes in one second (FEV1)/forced vital capacity (FVC) and adverse events were collected at baseline and 4 months after treatment. All results were evaluated for short-term efficacy of Omalizumab. GraphPad Prism 8.2.1 was used for statistic analysis. Results: Ten patients were collected, including 3 males and 7 females, aged (41.13±12.64) years old (x¯±s). Compared to results at baseline, the VAS scores of nasal obstruction, rhinorrhea, hyposmia and headache after 4 months treatment were significantly decreased (1.80±1.48 vs 6.70±2.83, 2.40±1.27 vs 6.40±3.44, 2.70±2.91 vs 8.20±2.25, 0.60±1.08 vs 3.60±2.72, t value was 5.045, 4.243, 5.312, 3.402, respectively, all P<0.01). The scores of SNOT-22 (25.6±20 vs 61.3±33.32, t=4.127, P=0.002 6), nasal polyp scores (2.20±0.92 vs 4.60±0.84, t=9.000, P<0.01) and the count and percentage of eosinophils in peripheral blood were significantly decreased ((94.10±97.78)×109/L vs (360.00±210.80)×109/L, (32.90±27.06)% vs (64.40±20.73)%, t value was 3.678, 2.957, respectively, all P<0.05). NCV (0-5 cm and 0-7 cm) of patients were improved from baseline ((12.62±2.84) cm3 vs (10.40±2.09) cm3, (27.50±14.15) cm3 vs (16.81±6.40) cm3, t value was 2.371, 2.445, respectively, all P<0.05). Conclusions: The 4-month treatment of Omalizumab can significantly improve the nasal symptoms and quality of life of patients with recurrent CRSwNP complicated with asthma, shrink nasal polyps size and reduce the number of peripheral blood eosinophils. Omalizumab can be used as an alternative therapy for refractory CRSwNP patients in the future.

Abstract
Objective: To evaluate the performance of the European Evidence-based Guidelines on Pancreatic Cystic Neoplasms (EEGPCN)(2018) and International Association of Pancreatology(IAP) Guideline(Version 2017) in predicting high grade dysplasia/invasive carcinoma-intraductal papillary mucinous neoplasm(HGD/INV-IPMN). Methods: A retrospective analysis of 363 patients,who underwent surgical resection in Changhai Hospital affiliated to Navy Medical University from January 2012 to December 2018 and were pathologically identified as (intraductal papillary mucinous neoplasm, IPMN),was performed. The patients,including 230 males and 133 females,aging (61.7±10.1) years(range:19 to 83 years). The proportion of HGD/INV-IPMN who met with the absolute indication(AI) of EEGPCN and high risk stigma(HRS) of IAP were compared. The binary Logistic regression analysis was used to find the independent risk factors of HGD/INV-IPMN.Eight combinations of risk factors derived from relative indication/worrisome feature or risk factors in this study,were made to evaluate the diagnostic efficacy. The area under curve(AUC) of receiver operating characteristics was used to evaluate the the cutoff value of risk factors(①CA19-9≥37 U/ml,②diameter of main pancreatic duct 5.0-9.9 mm,③enhancing mural nodule<5 mm,④(acute) pancreatiti,⑤acyst diameter ≥40 mm,⑤bcyst diameter ≥30 mm, ⑥thickened or enhancing cyst walls,⑦neutrophile granulocyte to lymphocyte ratio(NLR)≥2, ⑧cyst located in head, uncinate or neck,⑨carcinoembryonic antigen(CEA) ≥5 μg/L) number for predicting HGD/INV-IPMN.The accuracy,sensitivity,specificity,positive predictive value,negative predictive value,true positive,true negative,false positive,false negative,positive likelihood ratio,negative likelihood ratio,Youden index and F1 score were calculated. Results: Ninety-two patients(49.5%) of 186 ones who met AI and 85 patients(48.3%) of 176 ones who met HRS were respectively confirmed as HGD/INV-IPMN. In those patients who were not met AI,tumor location,thickened/enhancing cyst wall,CA19-9 elevated,NLR≥2 and CEA elevated were significantly (P<0.05) correlated with HGD/INV-IPMN. And tumor location(head/uncinate/neck vs. body/tail,OR=3.284,95%CI:1.268-8.503,P=0.014),thickened/enhancement cyst wall (with vs.without,OR=2.713,95%CI:1.177-6.252,P=0.019),CA19-9(≥37 U/L vs.<37 U/L, OR=5.086,95%CI:2.05-12.62,P<0.01) and NLR(≥2 vs.<2,OR=2.380,95%CI:1.043-5.434,P=0.039) were the independent risk factors of HGD/INV-IPMN. Patients with ≥4 risk factors of 9 in combination Ⅷ(①②③④⑤b⑥⑦⑧⑨) were diagnosed as HGD/INV-IPMN with the moderate accuracy(71.0%),moderate sensitivity (62.0%) and moderate specificity (73.0%). Patients with ≥4 risk factors of 9 in Combination Ⅶ(①②③④⑤a⑥⑦⑧⑨) were diagnosed as HGD/INV-IPMN with the highest specificity(83.0%) and patients with ≥3 risk factors of 8 in combination Ⅵ(①②③④⑤b⑥⑧⑨) were diagnosed as HGD/INV-IPMN with the highest sensitivity(74.0%). The AUC for diagnosis of HGD/INV-IPMN in combination Ⅵ,Ⅶ and Ⅷ were 0.72,0.75 and 0.75,respectively. Older patients and younger patients could respectively refer to combination Ⅶ and combination Ⅵ to improve the management of IPMN. Conclusions: Patients who meet AI of EEGPCN should undertake resection, otherwise the method we explored is recommended. The method of improvement for diagnosis of HGD/INV-IPMN is relatively applicable and efficient for decision-making of surgery, especially for younger patients with decreasing of missed diagnosis and elder patients with decreasing of misdiagnosis.

Abstract
Long non-coding RNAs (lncRNAs) are crucial in chronic liver diseases, but the specific molecular mechanism of lncRNAs in alcoholic fatty liver (AFL) remains unclear. In this study, we investigated the in-depth regulatory mechanism of mTOR affected by AIRN non-protein coding RNA (lncRNA-AIRN) in the development of AFL. LncRNA-AIRN was highly expressed in the liver tissues of AFL C57BL/6mice and oleic acid+alcohol (O+A)treated AML-12cells by using quantitative real-timePCR. RNA pull-down and RNA immunoprecipitation experiments demonstrated that there was an interaction between lncRNA-AIRN and mTOR, and that interference with lncRNA-AIRN could promote the mTOR protein level. Results ofcycloheximide-chase assay showed that the proteinlevel of mTOR was decreased with the treatment time after the knockdown of lncRNA-AIRN. Furthermore, the knockdown of lncRNA-AIRN reducedmTOR protein level by promoting the E3 ubiquitin ligase FBXW7-mediated ubiquitination.The lncRNA-AIRN/mTORaxis was involved in the regulation of the mitophagy of O+A treated hepatocytes, which was confirmed by the cell transfection and the MTT assay.SPSS 16.0 was used for analyzing data. The difference between the two groups was analyzed by performing Student's t-test, and ANOVA was used to analyze the difference when more than two groups. P values < 0.05 were considered to be significantly different.Our findings demonstrated that the knockdown of lncRNA-AIRN influencedmitophagy in AFL by promoting mTOR ubiquitination.

Abstract
Objective: To explore the effects of Wnt3a on the proliferation, migration and osteogenic differentiation of periodontal ligament stem cell (PDLSC) and to identify the role of Wnt3a in alveolar bone regeneration in mouse experimental periodontitis. Methods: The experiments were conducted by stimulating PDLSC using Wnt3a of 5 different concentrations (0, 20, 100, 200, 500 μg/L) respectively. Cell proliferation was detected by cell-counting assay, cell migration was evaluated by Transwell assay and the expressions of osteogenic related genes collagen Ⅰ (Col-Ⅰ), runt-related transcription factor 2 (Runx2) were examined by real-time quantitative PCR (RT-qPCR). Poly lactic-co-glycolic acid (PLGA)-Wnt3a-hyaluronic acid (HA) hydrogel was injected locally into the gingival sulcus of mice with experimental periodontitis. After 1, 2, 4, and 8 weeks of hydrogel injection, samples of maxillary alveolar bone were obtained. Micro-CT, HE staining and immunohistochemical staining of osteogenesis related markers, such as alkaline phosphatase (ALP), Runx2, osteocalcin (OCN), were used to evaluate alveolar bone regeneration. Results: After 10 d of culture, Wnt3a with concentrations of 20-500 μg/L significantly promoted the proliferation (P<0.01) and the migration (P<0.01) of PDLSC. After 21 d of culture, the expression levels of Col-Ⅰ mRNA were 0.96±0.27, 1.90±0.47, 2.18±0.24, 2.32±0.15 and 1.99±0.43 in 5 concentration groups respectively, and the expression levels of Runx2 mRNA were 1.08±0.15, 3.19±0.17, 6.19±0.28, 9.19±0.41 and 5.55±0.06, respectively. Both expressions had significant statistical differences compared with the negative control group (P<0.05). At 1, 2, 4, and 8 weeks, the Wnt3a hydrogel group had less distance [(497.3±18.2), (455.7±12.5), (401.0±8.5), (362.3±15.5) μm] from the cemento-enamel junction to alveolar bone crest compared with the periodontitis group [(710.3±10.2), (614.0±16.4), (564.3±12.5), (502.3±6.8) μm] (P<0.01) and weaker periodontal inflammation. Immunohistochemical results showed that the expression levels of bone-related proteins of ALP (0.72±0.01), Runx2 (0.77±0.03) and OCN (0.72±0.07) in the Wnt3a hydrogel group were increased compared with the periodontitis group (P<0.01). Conclusions: Wnt3a might promote the proliferation, migration and osteogenic differentiation of PDLSC and the alveolar bone regeneration.

Abstract
Objective: To compare the effects of artesunate (Art) and fuzheng huayu decoction on mitochondrial autophagy in the treatment of schistosomiasis liver fibrosis. Methods: Eighty C57BL/6 female mice were randomly divided into healthy control group, infection group, Art treatment group and Fuzheng Huayu Decoction treatment group, with 20 mice in each group. Mice in the infection group and treatment group were infected with 16 Schistosoma japonicum cercariae. After 6 weeks, praziquantel (300 mg/kg) was used for 2 days to kill the worms. The Art treatment group was treated with intraperitoneal injection of 100 mg/kg/day, while the Fuzheng Huayu Decoction treatment group was fed 16g of fuzheng huayu decoction per 1kg per day. After 6 weeks, fresh liver tissues of the four groups were collected. Masson staining and Western blot were used to observe the succinate dehydrogenase subunit A (SDHA) and malate dehydrogenase (MDH2), citrate synthase (CS), ketoglutarate dehydrogenase (OGDH), and target of rapamycin 1 (mTORC1) pathway involved in mitochondrial tricarboxylic acid cycle in liver tissues. The relative expression levels of adenylate activated protein kinase (AMPK) and mitochondrial autophagy pathway kinase (PINK1) were detected. Liver tissue samples were extracted from each group to detect the mitochondrial oxygen consumption rate. Two-way ANOVA was used to compare the significance and difference between two sets of samples. Results: Masson staining showed that the infection group mice had significantly higher liver fibrosis area than the healthy control group, while the Art treatment group and Fuzheng Huayu Decoction treatment group mice had lower liver fibrosis area than the infection group. Western blot analysis showed that the infection group (0.82±0.05) had significantly lower relative expression of SDHA protein than the healthy control group (1.00±0.05) (t = 11.23, P = 0.0035), while the Art treatment group (0.73±0.05) had significantly higher relative expression of SDHA protein than the infection group (t = 10.79, P = 0.0073). However, there was no significant change in Fuzheng Huayu Decoction treatment group (0.98±0.05) (t = 1.925,P= 0.1266). The relative expression of p-AMPK protein was significantly higher in the infection group (1.15 ±0.05) than in the healthy control group (0.98±0.07,t= 12.18, P = 0.0029), and the expression of p-AMPK in the Art treatment group (0.50±0.05) was significantly lower than the infection group (t = 11.78,P= 0.0032). The relative protein expression of AMPK was significantly lower in the infection group (0.80±0.05) than in the healthy control group (1.00±0.05, t= 10.53, P= 0.0046). The expression of AMPK was significantly lower in the Art treatment group (0.54±0.05) than in the infection group (T = 13.98, P = 0.0036). The relative expression of p-mTORC1 protein (0.93±0.08) was not significantly different in the infection group than in the healthy control group (t = 2.28, P = 0.065), while the Art treatment group (0.63±0.05) had significantly lower relative expression of p-mTORC1 protein than the infection group (t = 10.58, P = 0.029). The expression of p-mTORC1/m-TORC1 was not significantly different in the infection group (0.98±0.03) than in the healthy control group (0.97±0.03, t = 0.98, P = 0.085), while the Art treatment group (0.63±0.05) had significantly lower relative expression of p-mTORC1/m-TORC1 than the infection group (t = 14.58, P = 0. 009). The relative protein expression of PINK1 was significantly lower in the infection group (0.55±0.05) than in the healthy control group (1.00±0.03, t = 13.49, P = 0.0011), while the Art treatment group (1.21±0.05, t = 9.98, P = 0.0046) and Fuzheng Huayu Decoction treatment group (1.31 ±0.35, t = 6.98, P = 0.027) had significantly higher relative protein expression of PINK1 than the infection group. Mitochondrial function tests showed that after adding substrate complex II, the oxygen consumption of the infection group was lower than the healthy control group, while the Art treatment group and the Fuzheng Huayu Decoction treatment group had higher oxygen consumption than the infection group. The oxygen consumption was significantly lower after adding the substrate complex III in the infection group than the healthy control group, while the Art treatment group and Fuzheng Huayu Decoction treatment group had higher oxygen consumption than the infection group. Conclusion: Art can alleviate schistosomiasis liver fibrosis by inhibiting AMPK/mTORC1 signaling pathway activity and enhancing mitochondrial oxygen consumption, autophagy and SDHA expression.

Abstract
The structural and mechanical properties of tissue and the interplay between them play a critical role in tissue function. We introduce the optomechanogram, a combined quantitative and qualitative visualization of spatially co-registered measurements of the microstructural and micromechanical properties of any tissue. Our approach relies on the co-registration of two independent platforms, second-harmonic generation (SHG) microscopy for quantitative assessment of 3D collagen-fiber microstructural organization, and nanoindentation (NI) for local micromechanical properties. We experimentally validate our method by applying to uterine cervix tissue, which exhibits structural and mechanical complexity. We find statistically significant agreement between the micromechanical and microstructural data, and confirm that the distinct tissue regions are distinguishable using either the SHG or NI measurements. Our method could potentially be used for research in pregnancy maintenance, mechanobiological studies of tissues and their constitutive modeling and more generally for the optomechanical metrology of materials.

Abstract
OBJECTIVE This study aimed to assess the feasibility of the Clinical Frailty Scale (CFS) and clinical biomarkers in assessing the frailty in elder inpatients in China. DESIGN The study was a cross-sectional study. SETTING AND PARTICIPANTS The study included 642 elder inpatients (295 females and 347 males) aged ≥65 years, from the Department of Geriatrics of Zhejiang Hospital between January 2018 and December 2019. MEASUREMENTS All participants underwent a comprehensive geriatric assessment and blood tests. Univariate and multivariate logistic regression was used to analyze the association between risk factors and frailty. RESULTS The average age of the participants was 82.72±8.06 years (range: 65-95 years) and the prevalence of frailty was 39.1% according to the CFS. Frail participants showed significantly lower short physical performance battery (SPPB), basic activities of daily living (ADL) and instrumental activities of daily living (IADL) scores (all p<0.001), and lower hemoglobin, total protein and albumin levels (all P<0.05) than nonfrail participants. Frail participants had higher CRP, D-dimer and fibrinogen levels than nonfrail participants (all p<0.05). Univariate logistic regression analysis showed a significant association between frailty and age, comorbidity, polypharmacy, fall history, SPPB, ADL, and IADL scores, D-dimer, fibrinogen, hemoglobin, total protein and albumin levels (all P<0.05). Multivariate logistic regression analysis indicated that age (odds ratio (OR), 95% confidence interval (CI)= 1.151(1.042-1.272), P=0.006), SPPB scores (OR, 95% CI=0.901(0.601-1.350), P<0.001), and D-dimer (OR, 95% CI=4.857(2.182-6.983), P<0.001), fibrinogen (OR, 95% CI=2.665(0.977-4.254), P<0.001), hemoglobin (OR, 95% CI=0.837(0.725-0.963), P= 0.044), and albumin (OR, 95% CI=0.860 (0.776-1.188), P<0.001) levels were independently associated with frailty in all participants. CONCLUSION Frailty in elder inpatients in China is characterized by older age, a lower SPPB scores, higher D-dimer and fibrinogen levels and lower hemoglobin and albumin levels. Functional decline and malnutrition may be the targets of frailty interventions.

Abstract
Semi-allogeneic embryos are not rejected by the maternal immune system due to maternal-fetal immune tolerance. Progesterone (P) receptor (PR)-expressing γδ T cells are present in healthy pregnant women. In the presence of P, these cells secrete an immunomodulatory protein called progesterone-induced blocking factor (PIBF), which can facilitate immune escape and is important in preventing embryonic rejection. This work investigated the correlations of the expression of γδ T cells and their co-stimulatory molecules T cell immunoglobulin and ITIM domain (TIGIT), programmed cell death 1 (PD-1), inducible co-stimulator (ICOS) and B and T lymphocyte attenuator (BTLA) with progesterone receptor (PR) and progesterone-induced blocking factor (PIBF) in peripheral blood and decidual tissue in women with unexplained recurrent spontaneous abortion (URSA) and normal pregnant (NP) women. We confirmed that γδ T cell proportions and PIBF expression in the peripheral blood and decidua of URSA women decreased significantly, while PR expression in decidua decreased. However, TIGIT, PD-1, ICOS and BTLA expression in γδ T cells in peripheral blood did not change, while TIGIT and PD-1 expression in γδ T cells in decidua increased significantly. Under the action of PHA-P (10 µg/ml), co-blocking of TIGIT (15 µg/ml) and PD-1 (10 µg/ml) antibodies further induced γδ T cell proliferation, but PIBF levels in the culture medium supernatant did not change. At 10-10 M P, γδ T cells proliferated significantly, and PIBF concentrations in the culture medium supernatant increased. γδ T cells co-cultured with P, TIGIT and PD-1 blocking antibodies showed the most significant proliferation, and PIBF concentrations in the culture medium supernatant were the highest. These results confirm that P is necessary for PIBF production. The TIGIT and PD-1 pathways participate in γδ T cell proliferation and activation and PIBF expression and play important roles in maintaining pregnancy.

Abstract
BACKGROUND Gait and cognitive impairments are common in individuals with Multiple Sclerosis (MS) and can interfere with everyday function. Those with MS have difficulties executing cognitive tasks and walking simultaneously, a reflection of dual-task interference. Therefore, dual-task training may improve functional ambulation. Additionally, using technology such as virtual reality can provide personalized rehabilitation while mimicking real-world environments. The purpose of this randomized controlled trial is to establish the benefits of a combined cognitive-motor virtual reality training on MS symptoms compared to conventional treadmill training. METHODS This study will be a single-blinded, two arm RCT with a six-week intervention period. 144 people with MS will be randomized into a treadmill training alone group or treadmill training with virtual reality group. Both groups will receive 18 sessions of training while walking on a treadmill, with the virtual reality group receiving feedback from the virtual system. Primary outcome measures include dual-task gait speed and information processing speed, which will be measured prior to training, one-week post-training, and three months following training. DISCUSSION This study will provide insight into the ability of a multi-modal cognitive-motor intervention to reduce dual-task cost and to enhance information processing speed in those with MS. This is one of the first studies that is powered to understand whether targeted dual-task training can improve MS symptoms and increase functional ambulation. We anticipate that those in the virtual reality group will have a significantly greater increase in dual-task gait speed and information processing speed than those achieved via treadmill training alone.

Abstract
We present a supercomputer-driven pipeline for in-silico drug discovery using enhanced sampling molecular dynamics (MD) and ensemble docking. We also describe preliminary results obtained for 23 systems involving eight protein targets of the proteome of SARS CoV-2. THe MD performed is temperature replica-exchange enhanced sampling, making use of the massively parallel supercomputing on the SUMMIT supercomputer at Oak Ridge National Laboratory, with which more than 1ms of enhanced sampling MD can be generated per day. We have ensemble docked repurposing databases to ten configurations of each of the 23 SARS CoV-2 systems using AutoDock Vina. We also demonstrate that using Autodock-GPU on SUMMIT, it is possible to perform exhaustive docking of one billion compounds in under 24 hours. Finally, we discuss preliminary results and planned improvements to the pipeline, including the use of quantum mechanical (QM), machine learning, and AI methods to cluster MD trajectories and rescore docking poses.

Abstract
It is well-known that it is crucial to insert either a single InGaN underlayer or an InGaN superlattice (SLS) structure (both with low InN content) as a pre-layer prior to the growth of InGaN/GaN multiple quantum wells (MQWs) served as an active region for a light-emitting diode (LED). So far, this growth scheme has achieved a great success in the growth of III-nitride LEDs on c-plane substrates, but has not yet been applied in the growth of any other orientated III-nitride LEDs. In this paper, we have applied this growth scheme in the growth of semi-polar (11–22) green LEDs, and have investigated the impact of the SLS pre-layer on the optical performance of semi-polar (11–22) green LEDs grown on patterned (113) silicon substrates. Our results demonstrate that the semi-polar LEDs with the SLS pre-layer exhibit an improvement in both internal quantum efficiency and light output, which is similar to their c-plane counterparts. However, the performance improvement is not so significant as in the c-plane case. This is because the SLS pre-layer also introduces extra misfit dislocations for the semi-polar, but not the c-plane case, which act as non-radiative recombination centres.

背景与目的 晚肺腺癌是肺癌中最常见的类型,表皮生长因子受体酪氨酸激酶抑制剂(epidermal growth factor receptor tyrosine kinase inhibitors, EGFR-TKIs)目前已成为EGFR突变型非小细胞肺癌(non-small cell lung cancer, NSCLC)的一线标准治疗。经典型突变(19外显子缺失突变和21外显子L858R突变)应用EGFR-TKIs治疗的效果已有大量研究和报道,而少见或复合突变类型的相关报道较少,具体疗效尚未完全统一定论。 方法 对2016年8月-2018年4月就诊于郑州大学第一附属医院的150例经基因检测证实为EGFR少见突变的NSCLC患者进行回顾性研究,分析其突变类型及临床病理特征,并对其中48例接受EGFR-TKIs Ⅰ/Ⅱ/Ⅲ线治疗的患者的疗效进行描述和评价。 结果 将全部150例患者按突变类型分为4组,分别为18外显子G719X突变46例(30.7%)、21外显子L861Q突变45例(30.0%)、其他单一少见突变14例(9.3%)和复合突变45例(30%)。EGFR基因少见或复合突变类型与性别、年龄、分期、病理类型及吸烟史均无关。对于48例接受EGFR-TKIs治疗的患者,4组不同类型突变的患者客观缓解率(objective response rate, ORR)和疾病控制率(disease control rate, DCR)差异无统计学意义(54.5% vs 30.0% vs 0.0% vs 35.7%, χ2=3.200, P=0.34; 90.9% vs 85.0% vs 66.7% vs 92.9%, χ2=2.162, P=0.59)。中位无进展生存期(median progress free survival, mPFS)为11.0个月(95%CI: 4.4-17.6),在EGFR基因突变不同类型分组中分别为[15.8个月(95%CI: 9.5-22.2)、8.0个月(95%CI: 5.1-11.0)、4.9个月(95%CI: 1.4-8.4)、23.1个月(95%CI: 15.8-30.4)](χ2=7.876, P=0.049)。 结论 不同类型的EGFR少见或复合突变类型应用EGFR的疗效不尽相同,复合突变组PFS可能优于单一少见突变组。接下来有必要进一步进行大样本量的研究,发现新的敏感靶点和研究新一代的药物对于接受现有治疗效果欠佳的患者也是值得期待的。

Abstract
BACKGROUND Human epidermal growth factor receptor 2 (HER2) is one of the driver genes of non-small cell lung cancer (NSCLC). Several studies have shown that the efficacy of pemetrexed in HER2-mutant NSCLC is controversial. The aim of this study is to investigate the efficacy of pemetrexed combined with platinum chemotherapy in patients with HER2-mutant and HER2 wild-type lung adenocarcinoma. METHODS The clinical data of 106 cases of EGFR, ALK, ROS-1, KRAS, BRAF, RET and MET-negative patients with advanced lung adenocarcinoma patients who diagnosed by histopathology in the First Affiliated Hospital of Zhengzhou University were retrospectively reviewed. The relationships between HER2 gene status, clinical characteristics and response and progression-free survival (PFS) were analyzed. RESULTS All of the 106 patients' HER2 status were determined. HER2 mutations occurred in 32 cases (30.2%), no mutations in 74 cases (69.8%). HER2 mutations were common in young, non-smoking and female patients. All patients received first-line pemetrexed and platinum-based chemotherapy. The objective response rate (ORR) and disease control rate (DCR) of patients with HER2-mutant lung adenocarcinoma were significantly higher than those without HER2 mutations (40.6% vs 14.9%, χ²=8.464, P=0.004; 93.8% vs 68.9%, χ²=6.327, P=0.012), and the difference was statistically significant. According to univariate analysis, the PFS was significantly associated with the brain metastases, maintenance chemotherapy and HER2 gene status (P<0.05), but not with age, gender, smoking history, oligometastases, liver metastases and type of platinum (P>0.05). Cox multivariate analysis indicated that HER2 mutation was an independent positive prognostic factor of PFS (P=0.038). CONCLUSIONS HER2-mutant lung adenocarcinoma patients with first-line pemetrexed combined with platinum chemotherapy have greater clinical benefit than HER2 wild-type patients.

Abstract
To investigate the mtDNA variation and origin of maternal lineages in South American donkeys and to reassess the domestication of donkeys in northeast Africa, we analyzed sequences (489 bp of the D-loop) from 323 domestic donkeys sampled from Peru, Brazil, Ethiopia and Egypt. Altogether, the 323 sequences displayed 53 different haplotypes (45 in Ethiopia, 14 in Egypt, eight in Peru and six in Brazil). Among the four populations, Egyptian donkeys possessed the highest haplotype diversity (0.910 ± 0.032), followed by Brazilian donkeys (0.879 ± 0.060). The Clade I haplotypes dominated in Peruvian donkeys (65%), whereas Clade II haplotypes dominated in Brazilian donkeys (67%). Estimates of FST values showed a high genetic differentiation between Peruvian and Brazilian donkey populations (FST = 0.4066), which could be explained by the complex introduction history of South American donkeys. Phylogeographic analysis indicates that northeast Africa could be the most probable domestication center for Clade I donkeys. Analysis of molecular variance confirmed a weak genetic structure in domestic donkey populations among four continents (Europe, Asia, Africa and South America).

Abstract
Performing a mandibular symphyseal split and genioplasty simultaneously and accurately is a technical challenge for the surgeon. The aim of this study was to validate a reversed approach for simultaneous symphyseal split and genioplasty. A cutting guide and a repositioning guide were designed and printed three-dimensionally in titanium. The symphyseal split and genioplasty were performed successfully. The accuracy of the technique appears to be appropriate for clinical application.

Abstract
Abstract
Background: Some population-base studies have reported similar or improved survival for breast-conserving surgery (BCS) plus radiotherapy compared with mastectomy (Mx) in early breast cancer [PMID: 22373563, 27344114]. Among the screening detected early breast cancer, ultrasound (US) could detect more invasive non-palpable breast cancer (NPBC) with positive lymph nodes in hospital-based asymptomatic Chinese women, who could achieve comparable 10-year DFS and OS as mammography (MG)-detected NPBC [2016 SABCS P5-02-05, PMID: 27689334]. However, there is little data about the surgical outcomes of BCS verse Mx in the low-risk screening detected NPBC with US as the initial imaging test.
Methods: From 2001 to 2017, 6,423 consecutive asymptomatic women underwent mammography or ultrasound guided biopsy in Peking Union Medical College Hospital. Among them, 1130 NPBC including 914 US-detected and 216 MG-detected NPBC were diagnosed and treated. There were 349 (30.9%) patients underwent BCS including 286 (25.3%) patients received radiation therapy and 63 (5.6%) elderly patients (>70 years) who did not. The clinicopathological features, treatment choice, 10-year disease-free survival (DFS) and overall survival (OS) were compared between breast conservingsurgery (BCS) versus mastectomy(Mx) in all NPBC and between the US-detected and MG-detected NPBC.
Result: Compared to those who received BCS, the 781 (69.1%) patients who underwent Mx had more cancers with relatively higher histologic grade (p=0.003), positive lymph node (18.8% vs 12.0%, p=0.005), ER-negative (22.5% vs 11.5%, p<0.001), PR-negative (29.6% vs 16.3, p<0.001), Her2-positive (16.3% vs 8.9%, p=0.001), and received chemotherapy (37.6% vs 28.7%, p=0.003). The breast conserving rates of US-NPBCwere higher than that of MG-NPBC (32.6% vs 23.6%, p=0.010), but the breast conserving rates were similar between ductal carcinoma in situ (DCIS) and invasive cancers. The 10-year DFS and OS were similar among BCS with radiation therapy, BCS without radiation therapy and Mx as well as among US-NPBC with BCS, US-NPBC with Mx, MG-NPBC with BCS and MG-NPBC with Mx. However, MG-NPBC with Mx had favorable 10-year DFS than that of MG-NPBC with BCS (p=0.041).

Conclusion: The 10-year DFS and OS of breast conserving surgery versus mastectomy were similar among all NPBC patients. As the current initial imaging test, US-detected NPBC patients would receive significantly more BCS compared to MG. There was no significant difference in surgical outcomes among BCS and Mx in US-detected NPBC. However, among MG-detected NPBC, patients with Mx reached a better DFS but a similar OS than those with BCS. The radiation therapy could be safely omitted in the elderly patients (>70 years) with NPBC.

Abstract
Abstract
Background: Ultrasound (US) is an effective initial screening test for breast cancer both in Caucasian and Chinese women [PMID: 26712110, 26715161, and 25668012]. The real-world modality of breast cancer screening in the China is hospital-based screening among asymptomatic self-referred women. In our previous study, we showed that US and mammography (MG) detected non-palpable breast cancer (NPBC) had similar long-term survival and that US detected more invasive NPBC with positive lymph node [2016 SABCS P5-02-05, PMID: 27689334]. This study was to investigate whether these findings would be still true with more NPBC cases included and longer follow-up in the consecutive hospital cohort.
Methods: From 2001 to 2017, 5,264 asymptomatic women with positive (BI-RADS 4 and 5) initial screening US underwent biopsies in PUMC Hospital, and 914 US-NPBC in 883 women were diagnosed. Meanwhile, women without dense breasts (defined as BI-RADS category C and D) also received screening MG after physical examination and US. There were 1,159 patients with positive (BI-RADS 4 and 5) MG and normal US (BI-RADS 1, 2 and 3) underwent MG-guided biopsies and 216 MG-NPBC were diagnosed in 214 women. The clinicopathological characteristics and 10-year disease-free survival (DFS) and overall survival (OS) were reviewed and compared between the US-NPBC and MG-NPBC. Prognostic factors of NPBC were identified by univariate and multivariate Cox analysis.
Result: Compared to MG, US could detect more invasive (81.2% vs 48.6%, p<0.001), lymph node positive (18.3% vs 10.2%, p<0.001), stage II+III (21.7% vs 12.5%, p<0.001) and low grade cancer (p=0.001).Between invasive US-NPBC and MG-NPBC, no significant difference was identified for lymph node status, TNM stage or subtype.US-NPBC received more breast conserving surgery (32.6% vs 24.1%, p<0.001) and chemotherapy (37.5% vs 23.6%, p<0.001). There was no significant difference in DFS or OS between US- vs MG-NPBC among ductal carcinoma in situ (DCIS), invasive and all NPBC. For the US-NPBC, the DFS factors included TNM stage and Hormone receptor status whereas OS-predictors were pN and subtype.

Conclusion: Overall, US could detect more invasive NPBC patients with positive lymph node and advanced stage compared to MG, and screen invasive NPBC at similar TNM stage and subtype distribution as MG. US-NPBC patients received more breast conserving surgery and chemotherapy, and could achieve comparable 10-year DFS and OS as MG-detected NPBC. Hence US is justified in the real-world as the initial imaging modality in hospital-based screening Chinese women.
