Abstract
BACKGROUND Unidentified heart failure occurs in patients with multiple myeloma when their heart was involved. CMR with late gadolinium enhancement (LGE) and T1 mapping can identify myocardial amyloid infiltrations. PURPOSE To explore the role of CMR with late gadolinium enhancement (LGE) and T1 mapping for detection of multiple myeloma patients'heart. MATERIAL AND METHODS A total of 16 MM patients with above underwent CMR (3.0-T) with T1 mapping (pre-contrast and post-contrast) and LGE imaging. In addition, 26 patients with non-obstructive hypertrophic cardiomyopathy and 26 healthy volunteers were compared to age- and sex-matched healthy controls without a history of cardiac disease, diabetes mellitus, or normal in CMR. All statistical analyses were performed using the statistical software GraphPad Prism. The measurement data were represented by median (X) and single sample T test was adopted. Enumeration data were represented by examples and Chi-tested was adopted. All tests were two-sided, and P values < 0.05 were considered statistically significant. RESULTS In MM group, LVEF was lower than healthy controls and higher than that of non-obstructive hypertrophic cardiomyopathy group, but without statistically significant difference (%: 49.1 ± 17.5 vs. 55.6 ± 10.3, 40.4 ± 15.6, all P > 0.05). Pre-contrast T1 values of MM group were obviously higher than those of healthy controls and non-obstructive hypertrophic cardiomyopathy group (ms:1462.0 ± 71.3vs. 1269.3 ± 42.3, 1324.0 ± 45.1, all P < 0.05). 16 cases (100%) in MM group all had LGE. CONCLUSION LGE joint T1 mapping wider clinical use techniques and follow-up the patients'disease severity.

Abstract
OBJECTIVE To investigate the value of T2 mapping in the assessment of myocardial changes and prognosis in patients with acute ST segment elevation myocardial infarction (STEMI). METHODS A retrospective study was conducted. A total of 30 patients with acute STEMI admitted to Tianjin First Central Hospital from January 2021 to March 2022 were enrolled as the experimental group. At the same time, 30 age- and sex-matched healthy volunteers and outpatients with non-specific chest pain with no abnormalities in cardiac magnetic resonance (CMR) examination were selected as the control group. CMR was performed within 2 weeks after the diagnosis of STEMI, as the initial reference. A plain CMR review was performed 6 months later (chronic myocardial infarction, CMI). Plain scanning includes film sequence (CINE), T2 weighted short tau inversion recovery (T2-STIR), native-T1 mapping, and T2 mapping. Enhanced scanning includes first-pass perfusion, late gadolinium enhancement (LGE), and post-contrast T1 mapping. Quantitative myocardial parameters were compared between the two groups, before and after STEMI myocardial infarction. The receiver operator characteristic curve (ROC curve) was used to evaluate the diagnostic efficacy of native-T1 before myocardial contrast enhancement and T2 values in differentiating STEMI and CMI after 6 months. RESULTS There were no statistically significant differences in age, gender, heart rate and body mass index (BMI) between the two groups, which were comparable. The native-T1 value, T2 value and extracellular volume (ECV) were significantly higher than those in the control group [native-T1 value (ms): 1 434.5±165.3 vs. 1 237.0±102.5, T2 value (ms): 48.3±15.6 vs. 21.8±13.1, ECV: (39.6±13.8)% vs. (22.8±5.0)%, all P < 0.05]. In the experimental group, 12 patients were re-examined by plain CMR scan 6 months later. After 6 months, the high signal intensity on T2-STIR was still visible, but the range was smaller than that in the acute phase, and the native-T1 and T2 values were significantly lower than those in the acute phase [native-T1 value (ms): 1 271.0±26.9 vs. 1 434.5±165.3, T2 value (ms): 34.2±11.2 vs. 48.3±15.6, both P < 0.05]. ROC curve analysis showed that the area under the ROC curve (AUC) of native-T1 and T2 values in differentiating acute STEMI from CMI was 0.71 and 0.80, respectively. When native-T1 cut-off value was 1 316.0 ms, the specificity was 100% and the sensitivity was 53.3%; when T2 cut-off value was 46.7 ms, the specificity was 100% and the sensitivity was 73.8%. CONCLUSIONS The T2 mapping is a non-invasive method for the diagnosis of myocardial changes in patients with acute STEMI myocardial infarction, and can be used to to evaluate the clinical prognosis of patients.

Abstract
PURPOSE/OBJECTIVE(S) Delay in radiation therapy (RT) as part of multimodality therapy in Hodgkin (HL) and non-Hodgkin lymphoma (NHL) is associated with worse pain scores. In a heterogeneous cohort of lymphoma patients, we hypothesize that interdigitating RT before fewer (versus more) lines of chemotherapy (C) will be associated with lower opiate analgesic requirement. MATERIALS/METHODS From 2009-2019, patients with HL or NHL received palliative (36.5%) or definitive (63.3%) RT at a single institution. An IRB approved database with baseline treatment/disease characteristics, including oral morphine equivalent (OME) requirement, was reviewed. OME was recorded for a) 3-month period prior to RT, b) the month during RT, and c) 3 months after RT. Post-RT change in OME was calculated as the difference in "b" and "c" such that greater or less OME use post-RT was defined as positive or negative value respectively. We performed one-tailed t-test analyses to determine differences in OME during RT between different cohorts. Correlations between baseline characteristics and OME were performed using Spearman correlations, controlling for lymphoma subtype, stage, tumor volume, relapsed/refractory disease, duration of radiation and bulky disease. RESULTS Of 180 patients, 57.8% had NHL, 40.6% were stage IV and 29.4% had bulky disease. At median of 19 days [6-80] from diagnosis, 74% of patients received C with a median of 2 lines [1-4] before RT. The median interval from diagnosis to RT was 11 months [4-36]. Pearson correlation showed a negative association between time from diagnosis to RT and postRT OME in the definitive cohort (R2 = 0.42, F = 4.54, p = 0.002) such that the longer the time to RT, the larger the decrease in OME postRT as compared to during RT. T-test showed higher mean OME during RT for those receiving > 2 lines of C preRT (148.3mg) as compared to those receiving ≤ 2 lines before RT (51.5mg, p = 0.02). In patients receiving definitive RT, the difference remained significant: those receiving >2 lines of C had higher OME during RT as compared to those receiving ≤ 2 lines (207.5mg versus 48.3mg, p = 0.02). The difference in mean OME for patients receiving >2 C lines versus ≤ 2 lines was not significantly different in the palliative cohort (75.6 vs 60.6, p = 0.33). OME use during RT was also found to be higher in patients with bulky disease as compared to non-bulky disease (175.7 versus 52.0, p = 0.04). CONCLUSION In our single-center experience, patients who received >2 lines of C prior to RT were found to have a significantly higher mean OME requirement during RT. In patients receiving definitive RT, longer time to receipt of RT was found to be associated with a larger decrease in OME post-RT, likely related to starting with a higher OME. Interdigitation of RT early on, prior to the 3rd line of chemotherapy, may help reduce pain and improve quality of life.

Abstract
PurposeThe aim of this study is to investigate the cross-sectional and longitudinal associations between sensory impairments (SIs) including single vision impairment (SVI), single hearing impairment (SHI), and dual sensory impairments (DSI) with social isolation in the middle-aged and older Chinese population.MethodsData were obtained from the China Health and Retirement Longitudinal Survey (CHARLS). In total, 11,674 Chinese older adults aged over 45 were included at baseline 2011, and 6,859 participants who accomplished all four interviews from 2011 to 2018 were adapted for longitudinal analyses. Sensory status and social isolation measurements including social disconnectedness and self-perceived loneliness were collected. Assessment of social disconnectedness included the number of types of social activities in which they participated and the frequency of such participation. Loneliness referred to the subjective perception of loneliness. Other covariates included socio-demographic characteristics, medical conditions, and lifestyle-related factors. The impacts of baseline sensory status on social disconnectedness and loneliness were assessed using univariate and multivariate generalized linear models. A generalized linear model with generalized estimation equations (GEE) was used to assess the association between time-varying sensory statuses with social disconnectedness or loneliness over 8 years after being adjusted with multi-confounding factors.ResultsParticipants with SIs had significantly higher levels of social disconnectedness and self-perceived loneliness, compared to those who were free of SI. All kinds of SIs were significantly associated with loneliness according to both cross-sectional and longitudinal data. The correlations between DSI and social disconnectedness or loneliness at baseline and over 8 years were also noticed. SHI was found to be significantly associated with both frequency and types of social activities according to cross-sectional data and with the frequency of social activity participation in longitudinal analysis. SVI was only associated with the types of social activities at baseline (all p-values < 0.05).ConclusionSensory impairments, especially dual sensory impairments, have explicitly detrimental effects on social isolation among the older Chinese population. Over time, single hearing impairment specifically jeopardizes their frequency rather than types of social activities participation.

Abstract
BACKGROUND The emergence of the severe acute respiratory syndrome coronavirus 2 omicron variant has been triggering the new wave of coronavirus disease 2019 (COVID-19) globally. However, the risk factors and outcomes for radiological abnormalities in the early convalescent stage (1 month after diagnosis) of omicron infected patients are still unknown. METHODS Patients were retrospectively enrolled if they were admitted to the hospital due to COVID-19. The chest computed tomography (CT) images and clinical data obtained at baseline (at the time of the first CT image that showed abnormalities after diagnosis) and 1 month after diagnosis were longitudinally analyzed. Uni-/multi-variable logistic regression tests were performed to explore independent risk factors for radiological abnormalities at baseline and residual pulmonary abnormalities after 1 month. RESULTS We assessed 316 COVID-19 patients, including 47% with radiological abnormalities at baseline and 23% with residual pulmonary abnormalities at 1-month follow-up. In a multivariate regression analysis, age ≥ 50 years, body mass index ≥ 23.87, days after vaccination ≥ 81 days, lymphocyte count ≤ 1.21 × 10-9/L, interleukin-6 (IL-6) ≥ 10.05 pg/mL and IgG ≤ 14.140 S/CO were independent risk factors for CT abnormalities at baseline. The age ≥ 47 years, presence of interlobular septal thickening and IL-6 ≥ 5.85 pg/mL were the independent risk factors for residual pulmonary abnormalities at 1-month follow-up. For residual abnormalities group, the patients with less consolidations and more parenchymal bands at baseline could progress on CT score after 1 month. There were no significant changes in the number of involved lung lobes and total CT score during the early convalescent stage. CONCLUSION The higher IL-6 level was a common independent risk factor for CT abnormalities at baseline and residual pulmonary abnormalities at 1-month follow-up. There were no obvious radiographic changes during the early convalescent stage in patients with residual pulmonary abnormalities.

Abstract
BACKGROUND Immune-related hepatitis is one of the prevalent adverse events associated with immunotherapy, especially immune checkpoint inhibitors (ICIs). For patients without a history of liver disease, autoimmune disease, or alcohol consumption, it is not clear whether immune-related hepatitis could rapid progress to immune-related cirrhosis. CASE REPORT We report the case of a 54-year-old female with stage IIIB primary pulmonary lymphoepithelioma-like carcinoma (PLELC) diagnosed with immune-related hepatitis. After 15 months, a liver biopsy demonstrated the rapid progression of liver cirrhosis although systematic corticosteroid administration. CONCLUSIONS Long-term immune activation caused by ICIs may exacerbate the process of cirrhosis. Great attention should be paid to the rapid progression to liver cirrhosis of immune-related hepatitis in the clinic.

Abstract
1. This study measured six reproduction traits in a Sichuan white goose population (209 individuals), including fertility, qualified egg rate, plasma concentrations of progesterone (P), follicle-stimulating hormone (FSH), prolactin (PRL) and oestrogen (E2).2. Whole-genome resequencing data from the same goose population (209 individuals) were used in a genome-wide association study (GWAS) utilising a mixed linear model to investigate the genes and genetic markers associated with reproduction traits. The frequency of the selected SNPs and haplotypes were determined using the Matrix-Assisted Laser Desorption Ionisation Time-Of-Flight Mass Spectrometry (MALDI-TOF MS) method.3. In total, 42 SNPs significantly associated with these traits were identified. A haplotype block was constructed based on five SNPs that were significantly associated with qualified egg rate, with individuals having the haplotype CCTTAAGGAA having the lowest qualified egg rate.4. In conclusion, these results provided potential markers for marker-assisted selection to improve goose reproductive performance and a basis for elucidating the genetics of goose reproduction.

Abstract
OBJECTIVE To explore the diagnostic performance of cardiac magnetic resonance imaging (CMR) with T1 mapping and T2 mapping for detection of acute phase of ischemic cardiomyopathy. METHODS Twenty-four patients with acute myocardial infarction (AMI) detected by coronary angiography from May 2020 to April 2021 in Tianjin First Center Hospital were selected. All patients underwent CMR (Philips Ingenia 3.0-T) at (9±4) days after definite diagnosis, which was defined as the first diagnosis. After 3 months and 6 months of chronic myocardial infarction (CMI) phase, one CMR was performed. On the same period with age and sex matching, a total of 26 cases of healthy volunteers and outpatient with non-specific chest pain and CMR examination without abnormality as control group. Plain scan included Cine, T2-weighted (STIR), and native T1/T2 mapping. The enhanced scan included perfusion, late gadolinium enhancement, post-T1 mapping. The changes of myocardial quantitative parameters before and after myocardial infarction were compared. Receiver operator characteristic curves (ROC curve) were developed to evaluate, compare, and distinguish the changes in the AMI group and the CMI group after 6 months. RESULTS Pre-enhanced T1 value, T2 value and extracellular volume (ECV) of AMI group were significantly higher than those of control group [pre-enhanced T1 value (ms): 1 438.7±173.4 vs. 1 269.2±42.3, pre-enhanced T2 value (ms): 49.8±9.3 vs. 21.7±4.0 , ECV (%): 33.2±10.2 vs. 27.2±2.1, all P < 0.05]. ECV was significantly higher in AMI (%: 33.2±10.2 vs. 27.2±2.1), but stabilized after 3 months (%: 33.2±10.2 vs. 32.4±5.1), and after 6 months later (%: 27.7±4.9 vs. 32.4±5.1), there were no significant difference (all P > 0.05). Pre-enhanced T1 and T2 values were significantly higher in AMI, lower after 3 months, but significantly decreased after 6 months [pre-enhanced T1 values (ms): 1 438.7±173.4 vs. 1 272.1±25.2, pre-enhanced T2 values (ms): 49.8±9.3 vs. 29.0±4.0, all P < 0.05]. The ROC curve showed that the specificity of pre-enhanced T1 and T2 values between AMI and CMI were 100%, and the sensitivity were 72.7%, 100%, respectively, pre-enhanced T1 and T2 value could be better distinguish between AMI and CMI diagnosis method. CONCLUSIONS T1 mapping and T2 mapping with ECV can clearly diagnosis ischemic cardiomyopathy, especially pre-enhanced myocardial T1 and T2 values which is non-invasive diagnosis method of AMI, and can distinguish AMI or CMI, has a great significance to the patient's clinical treatment and follow-up.

Abstract
Background The stroke screening survey (SSS) is an essential strategy for stroke prevention. However, previous studies rarely discussed the effect of SSS on the acute phase treatment procedure for acute ischemic stroke (AIS) and the long-term prognosis outcomes. This study aims to investigate the effect of SSS on intravenous thrombolysis and long-term outcomes in AIS patients. Methods The stroke patients included were collected from Jiading Residences Community Health Records and Shanghai Stroke Service System database, from January 2017 to December 2019. Patients were divided into two groups, according to whether they have been screened before the event (onset and death). Demographic characteristics and treatment information of patients in the two groups were compared by the Mann-Whitney test and Chi-square test. The demographic differences between groups were adjusted with Propensity Score Matching (PSM) to evaluate the effect of SSS on door-to-needle time (DNT). The Kaplan-Meier survival curve with a log-rank test and multiple Cox regression model were used to evaluate the effect of SSS on long-term lifetime. Results A total of 1,236 patients with AIS were collected, including 468 (37.86%) female, 126 (10.19%) patients with intravenous thrombolysis, 241 (23.30%) patients died from all-cause mortality by January 8, 2020. A total of 124 (10.03%) patients have been screened before AIS onset, and 261 (21.17%) patients had undergone SSS after AIS onset. The baseline information indicated that patients with previous screening were older than the patients without at the time of onset [75 (70, 83) vs. 73 (65, 82), P=0.017], as well as more likely to have a history of hypertension (90.32% vs. 78.51%, P=0.002) and diabetes (50.00% vs. 25.81%, P<0.001). PSM results showed that patients with previous screening were associated with less severe onset situation [3 (1, 9) vs. 3 (1, 5), P=0.001] and shorter DNT [30 (24, 49) vs. 44 (31.5, 49), P=0.037] when compared to patients without. Additionally, patients with SSS had a lower hazard ratio of 0.567 (95% CI: 0.380–0.847, P=0.006) on all-cause mortality. Conclusions For AIS patients, the SSS is associated with less severe onset situation, shorter DNT, and longer long-term lifetime.

Abstract
Background The purpose of this study is to investigate and analyze the prevalence and influencing factors of stroke in hypertensive patients aged 60 and above in Jiading District, Shanghai. Methods The population-based study included 18,724 screened people with hypertension (age ≥ 60 years, 48.7% women). From 2016 to 2019, data on demographics, potential influencing factors and health status were collected through face-to-face interviews, physical examinations, and laboratory tests. Logistic multivariate logistic regression model was used to analyze the influencing factors associated with stroke. Results Among the object of study from 2016 to 2019, 2,025 patients were screened for stroke, with the overall prevalence rate of 10.82% (10.41%-11.23%). Multivariate adjusted model analysis showed that dyslipidemia (OR:1.31,95%CI:1.19–1.45), lack of exercise (OR:1.91,95%CI:1.32–2.76), atrial fibrillation [OR:1.49,95%CI:1.35–1.65), family history of stroke (OR:2.18,95%CI:1.6–2.88) were the significant independent influencing factors of stroke in hypertensive patients over 60 years old. When these four factors were combined, compared with participants without any of these factors, the multi-adjusted odds ratios (95% confidence interval) of risk of stroke for persons concurrently having one, two and three or more of these factors were 1.89 (1.67–2.13), 2.15 (1.86–2.47) and 6.84 (4.90–9.55), respectively (linear trend P < 0.001); after multivariate adjustment, the family history of stroke had additive interaction with lack of exercise [RERI = 1.08(0.22–1.94), AP = 0.19(0.04–0.35), S = 1.31(1.02–1.69)], dyslipidemia [RERI = 0.87(0.41–1.33), AP = 0.23(0.08–0.38), S = 1.46(1.04–2.05)]. Conclusion The prevalence of stroke was high in hypertensive patients aged 60 and above in Jiading District, Shanghai. Dyslipidemia, lack of exercise, atrial fibrillation and family history of stroke were significantly associated with stroke in hypertensive population. Stroke risk can be increased especially when multiple factors coexisting, and family history of stroke combined with a lack of exercise or dyslipidemia.

Abstract
OBJECTIVE To explore the role of T1 mapping and late gadolinium enhancement (LGE) for detection of dilated cardiomyopathy (DCM). METHODS Thirty-two DCM patients detected by ultrasonic testing with unknown origin heart failure from April 2018 to November 2019 were involved. In addition, they were compared with 18 physical examiner under cardiac magnetic resonance imaging (CMRI) in the same period. Phillip's Ingenia 3.0T MRI was used to examine heart function, plain scan included cine, T2 weighted imaging (T2WI) and pre-contrast native T1 mapping. The enhancement scan included perfusion weighted imaging, LGE imaging and post-contrast post T1 mapping. Using gadolinium injection, a bolus of 0.1 mL/kg of gadolinium-based contrast followed by a 20 mL saline flush was administered. After a 7-minute later start scanning, delay enhance sequence was started, including 4 layers, 2 cavities and 4 cavities. LGE and T1 mapping results were observed, including cardiac function indexes [left ventricular end-diastolic volume (LVEDV), left ventricular end-systolic volume (LVESV), left ventricular ejection fraction (LVEF), valvular regurgitation], cardiac morphological indexes [left ventricular mass (LVM)], histological characteristics (T2WI myocardial signal, presence of perfusion defect and its position and scope, presence of delayed enhancement and its position, shape and scope, pre- and post-contrast T1 values), extracellular volume (ECV) and the accompanying signs (pericardial effusion and pleural effusion). The receiver-operating characteristic curve (ROC) was drawn, the diagnostic value of T1 value of pre-contrast T1 mapping for DCM was evaluated, and the occurrence of clinical endpoint events was observed. RESULTS There were no statistically significant differences in DCM patients with gender, age, body mass index (BMI), blood pressure, heart rate (HR), hematocrit (HCT), creatinine (Cr), family history of hypertension or heart disease. In DCM group N-terminal brain natriuretic peptide precursor (NT-proBNP) level and proportion of patients with heart function level III, diabetes, smoking history, drinking history and medication history were significantly higher than those in control group. Compared with control group, LVEDV (mL/m2: 234.9±35.9 vs. 121.8±27.6), LVESV (mL/m2: 189.7±42.8 vs. 54.8±17.0), LVM (g: 197.6±56.3 vs. 110.5±22.9), pre-contrast T1 values (ms: 1 332.1±35.9 vs. 1 272.0±47.0), ECV [(45.7±4.9)% vs. (28.0±2.1)%] were significantly increased in the DCM group; LVEF (0.191±0.107 vs. 0.554±0.103), post-contrast T1 values (ms: 453.9±72.7 vs. 493.5±43.9) were significantly decreased (all P < 0.05). In DCM group, the proportions of valvular regurgitation, pericardial effusion and pleural effusion were 25.0%, 18.8% and 25.5%, respectively. ROC curve analysis showed that the cutoff value of pre-contrast T1 values was 1 220.22 ms, the area under ROC curve (AUC) was 0.84 (P = 0.015), the sensitivity and specificity were 77.8% and 88.9%, indicating that pre-contrast T1 values may be a certain prediction for diagnosis of DCM. In 32 patients with DCM, 22 cases (68.8%) had LGE in position wall, interventricular septum, inferior wall or under the epicardium, with local or multiple diffuse, 9 cases (28.1%) were both interventricular septum and inferior wall involved. During an average of 16 months follow-up, 3.1% patients appeared sudden cardiac death. CONCLUSIONS One-stop CMRI can improve the diagnostic efficacy of DCM, and T1 mapping with LGE imaging can improve the diagnostic accuracy, which is very meaningful for diagnosis and follow-up of patients.

Abstract
Large phenotypic differences have been observed between Tongcheng and Large White pigs. However, little is known about their genetic basis. This study performed a genome-wide comparison of CNVs between Tongcheng and Large White pigs using genome sequencing data. By combining the advantages of three different strategies (read depth, paired-end mapping and split read), we detected in total 18 687 CNVs that covered approximately 3.5% of the pig genome length for Tongcheng and Large White pigs. We identified 1864 breed-stratified CNVs (top 10%) by performing VST statistics. Functional enrichment analyses for genes located in breed-stratified CNVs were found to be involved in pigmentation, behavior, immune system and reproductive processes, which coincide with phenotypic differences between the two breeds. Using a systematic analysis of the genome and transcriptome data, we further identified four novel breed-differential CNVs on the functional genes (disease-resistant, DCUN1D2 and SPARCL1; lipid metabolism, PLEKHA2 and SLCO1A2). Subsequent PCR validation confirmed their accurate breakpoint positions in 33 Tongcheng pigs and 33 Large White pigs. This study provides essential information on differential CNVs for further research on the genetic basis of phenotypic differences between Tongcheng and Large White pigs.

Abstract
OBJECTIVE The aim of this research is to explore the possible role of miR-152 in spinal cord injury and its underlying mechanism. MATERIALS AND METHODS After a mouse model of spinal cord injury (SCI) was developed, Real Time-quantitative Polymerase Chain Reaction (RT-qPCR) was used to detect the expression of miR-152 and c-jun in the mouse. In addition, the expression levels of interleukin-1b (IL-1b), interleukin-18 (IL-18) and tumor necrosis factor-α (TNF-α) were detected by enzyme-linked immunosorbent assay (ELISA). Subsequently, miR-152 was overexpressed and the levels of inflammation and c-jun after spinal cord injury were detected by Western blot. Furthermore, the grip strength of double forelimb, left forelimb or right forelimb of the mice was detected using a grip force test after miR-152 was overexpressed in the injured area of each group. RESULTS By constructing a mouse model of spinal cord injury, we found that the expression of miR-152 in the injured area decreased with time; meanwhile, the inflammatory relative genes including IL-1b, IL18, TNF-α, and c-jun were significantly increased. However, miR-152 overexpression significantly reduced the levels of inflammation genes as well as the expression of c-jun. Besides, the strength of the forelimbs in the spinal cord injury mice was restored. CONCLUSIONS MiR-152 could inhibit inflammatory responses and promote the recovery of the spinal cord injury through the c-jun N-terminal kinase pathway and it can be a target molecular for treating spinal cord injury.

Abstract
Objective: To investigate the clinicopathological and molecular characteristics of pulmonary enteric adenocarcinoma (PEAC). Methods: The clinical and pathological data of 19 cases of PEAC in the Affiliated Cancer Hospital of Zhengzhou University were retrospectively collected from 2015 to 2019. Immunohistochemistry (IHC) was used to detect the relevant immunophenotypes, amplification refractory mutation system (ARMS) and fluorescence in situ hybridization (FISH) were used to detect the expression of EGFR, KRAS and ALK genes. The patients were followed up, and the relevant literature was reviewed and analyzed. Results: There were 19 cases, including 10 males and 9 females, with a mean age of 58 years (range 33-71 years). Microscopically, the tumors showed moderately to highly differentiated adenoid and/or papillary growth patterns. The tumor cells were highly columnar and sometimes showed pseudostratification. Inflammatory necrosis and scattered nuclear fragmentation were seen in some glandular lumens. IHC showed variable expression of CK7 (19/19), TTF1 (8/19), Napsin A (6/19), villin (17/19), CK20 (16/19) and CDX2 (10/19). Molecular testing showed KRAS mutation in nine cases (9/19), EGFR mutation in one case (1/19), and positive ALK split signal in one case (1/19). In the literature, the reported mutation rate of KRAS in PEAC was much higher than that of EGFR and ALK. All 19 cases underwent surgical resection and 11 cases were subjected to chemotherapy or radiotherapy. Conclusions: PEAC is a rare variant of invasive pulmonary adenocarcinoma, and has similar histological and cytological features to that of colorectal adenocarcinoma. However, detailed medical history, histologic heterogeneity, an IHC combination of CK7(+)/villin(+) and high KRAS mutation rate are the key points of diagnosis. The prognosis needs long-term follow-up and big data statistics.

Abstract
1. Egg-laying traits are important economic characteristics in goose production (Anser cygnoides). The gene GnRH, which encodes gonadotropin-releasing hormone, is a strong candidate gene for egg-laying traits in avian species. 2. In this study, a 3520 bp genomic sequence and a 279 bp mRNA sequence for GnRH, which encoded 92 amino acids, were determined. The GnRH DNA sequence contains four exons and three introns, and the DNA and deduced amino acid sequences were highly conserved across mammals (human, macaque, cow, and sheep) and avians (chicken, fulmar and quail). 3. Using a direct sequencing method, 46 single nucleotide polymorphisms (SNPs) were identified in the GnRH genomic sequence that were shared between two Sichuan White goose populations (217 and 208 individuals). Furthermore, 44 haplotypes were constructed using a sliding window approach. Association analysis between the SNPs and haplotypes and egg-laying traits showed that 10 SNPs affected the first egg weight, average egg weight, egg number at 48 weeks and egg number at 64 weeks. 4. These results lay the foundation for further studies of the function of GnRH in geese and provide a theoretical basis for marker-assisted selection of egg-laying traits in the Sichuan white goose population.

Abstract
BACKGROUND Effective targeted therapy for non-small-cell lung cancer (NSCLC) patients with human epidermal growth factor receptor 2 (HER2) mutations remains an unmet need. This study investigated the antitumor effect of an irreversible pan-HER receptor tyrosine kinase inhibitor, pyrotinib. PATIENTS AND METHODS Using patient-derived organoids and xenografts established from an HER2-A775_G776YVMA-inserted advanced lung adenocarcinoma patient sample, we investigated the antitumor activity of pyrotinib. Preliminary safety and efficacy of pyrotinib in 15 HER2-mutant NSCLC patients in a phase II clinical trial are also presented. RESULTS Pyrotinib showed significant growth inhibition of organoids relative to afatinib in vitro (P = 0.0038). In the PDX model, pyrotinib showed a superior antitumor effect than afatinib (P = 0.0471) and T-DM1 (P = 0.0138). Mice treated with pyrotinib displayed significant tumor burden reduction (mean tumor volume, -52.2%). In contrast, afatinib (25.4%) and T-DM1 (10.9%) showed no obvious reduction. Moreover, pyrotinib showed a robust ability to inhibit pHER2, pERK and pAkt. In the phase II cohort of 15 patients with HER2-mutant NSCLC, pyrotinib 400 mg resulted in a objective response rate of 53.3% and a median progression-free survival of 6.4 months. CONCLUSION Pyrotinib showed activity against NSCLC with HER2 exon 20 mutations in both patient-derived organoids and a PDX model. In the clinical trial, pyrotinib showed promising efficacy.

Abstract
1. The study objectives were to determine the direct effects of gonadotropin-releasing hormone (GnRH) on the proliferation of ovarian granulosa cells (GCs) and the development of follicles in geese (Anser cygnoides) by colorimetry and ethynyl-2'-deoxyuridine (EdU) cell proliferation assays, in which primary GCs were treated with different concentrations of GnRH agonist (alarelin acetate) and an antagonist (cetrorelix acetate). Differently expressed genes (DEGs) were identified by RNA-sequencing and validated by quantitative reverse transcription polymerase chain reaction (RT-qPCR) and Western blotting. 2. The EdU assays showed that the proliferation of GCs was affected by the GnRH agonist and antagonist in a dose-dependent manner. The effect of treatment on cell proliferation was statistically significant at the concentrations of 10-5 mol/l alarelin and 1 mg/l cetrorelix acetate. A total of 134 DEGs (76 downregulated and 58 upregulated for alarelin treatment) and 226 DEGs (90 downregulated and 136 upregulated for cetrorelix) were identified by RNA-sequencing analysis, respectively. Enrichment analysis indicated that DEGs were enriched in the GO terms of cell-cell signalling and cell junctions. The pathways that regulate the development of follicles were identified, including the biological progress of cAMP accumulation, ovulation cycle and vasculature that are essential to follicular selection. 3. The results suggested that GnRH might directly regulate GC proliferation via autocrine or paracrine pathways related to cell junctions. In particular, it was confirmed that the mRNA and protein expression levels of the oestrogen receptor 2 (ESR2) gene, a negative transcription factor involved in follicular maturation and ovulation, were affected by GnRH agonist or antagonist in GCs. 4. In conclusion, GnRH might play an important role in follicular development by changing the expression of genes that participate in cAMP accumulation, ovulation cycle and cell junctions in ovarian GCs.

Abstract
Several of the key issues of planar (Al,Ga)N-based deep-ultraviolet light-emitting diodes could potentially be overcome by utilizing nanowire heterostructures, exhibiting high structural perfection, and improved light extraction. Here, we study the spontaneous emission of GaN/(Al,Ga)N nanowire ensembles grown on Si(111) by plasma-assisted molecular beam epitaxy. The nanowires contain single GaN quantum disks embedded in long (Al,Ga)N nanowire segments essential for efficient light extraction. These quantum disks are found to exhibit intense light emission at unexpectedly high energies, namely, significantly above the GaN bandgap, and almost independent of the disk thickness. An in-depth investigation of the actual structure and composition of the nanowires reveals a spontaneously formed Al gradient both along and across the nanowire, resulting in a complex core/shell structure with an Al-deficient core and an Al-rich shell with continuously varying Al content along the entire length of the (Al,Ga)N segment. This compositional change along the nanowire growth axis induces a polarization doping of the shell that results in a degenerate electron gas in the disk, thus screening the built-in electric fields. The high carrier density not only results in the unexpectedly high transition energies but also in radiative lifetimes depending only weakly on temperature, leading to a comparatively high internal quantum efficiency of the GaN quantum disks up to room temperature.

Abstract
We investigate the occurrence of interfacial reactions during the self-assembled formation of GaN nanowires on Ti/Al2O3(0001) substrates in plasma-assisted molecular beam epitaxy. The conditions typical for the synthesis of ensembles of long nanowires (>1 μm) are found to promote several chemical reactions. In particular, the high substrate temperature leads to the interdiffusion of Al and O at the Ti/Al2O3 interface resulting in the formation of Al x Ti y O1-x-y and Ti x O1-x compounds. Furthermore, O is found to incorporate into the nanowires degrading their luminescence by heavy n-type doping. At the same time, impinging Ga and N species react with the substrate giving rise to the simultaneous formation of single-crystalline TiN and Ga x Ti y O1-x-y compounds. The latter compounds tend to form hillocks at the substrate surface, on top of which nanowires elongate with large tilt angles with respect to the substrate normal. We develop here a specific process in order to mitigate the detrimental effects of these interfacial reactions, while maintaining the low areal density and absence of coalescence which is the strong asset of growing nanowires on Ti/Al2O3. We find that the combination of a thick Ti film with an intentional low temperature nitridation step preceding nanowire growth and a limited growth temperature results in ensembles of uncoalesced and well-oriented nanowires with luminescence properties comparable to those of standard GaN nanowires prepared on Si. All these properties, together with the inherent benefits of integrating semiconductors on metals, make the present materials combination a promising platform for the further development of group-III nitride nanowire-based devices.

Abstract
Objective: To investigate the therapeutic effect of psychological intervention combined with diazepam on sudden hearing loss patients with anxiety. Method: 108 cases of sudden hearing loss patients with anxiety were randomly divided into two groups(n=54 in each group): The control group received routine treatment of sudden hearing loss, the study group was given psychological intervention combined with diazepam tablets(2.5 mg once, twice a day) based on the routine treatment. The hearing and HAMA and SAS scores were reviewed after 10 days of treatment. Result: After 10 days of treatment, the average hearing threshold of patients in the control group and the study group were respectively increased by (19.65±7.89)dB and (26.93±9.04)dB (t=4.54, P=0.006), the HAMA score of two groups were respectively decreased by 4.68 and 10.75(t=9.949, P=0.000)and the SAS score of two groups were respectively decreased by 15.93 and 23.39 (t=6.773, P=0.000), and the total efficiency of hearing of two groups were 61.11% and 77.78% (χ²=4.441, P=0.035),respectively. the differences were statistically significant. Conclusion: Psychological intervention combined with diazepam can relieve anxiety in patients with sudden hearing loss effectively, and play a positive role in the development and prognosis of patients with sudden sensorineural hearing loss.
