Abstract
MET amplification (METamp) represents a promising therapeutic target in non-small cell lung cancer, but no consensus has been established to identify METamp-dependent tumors that could potentially benefit from MET inhibitors. In this study, an analysis of MET amplification/overexpression status was performed in a retrospectively recruited cohort comprising 231 patients with non-small cell lung cancer from Shanghai Chest Hospital (SCH cohort) using 3 methods: fluorescence in situ hybridization (FISH), hybrid capture-based next-generation sequencing, and immunohistochemistry for c-MET and phospho-MET. The SCH cohort included 130 cases known to be METamp positive by FISH and 101 negative controls. The clinical relevance of these approaches in predicting the efficacy of MET inhibitors was evaluated. Additionally, next-generation sequencing data from another 2 cohorts including 22,010 lung cancer cases were utilized to examine the biological characteristics of different METamp subtypes. Of the 231 cases, 145 showed MET amplification/overexpression using at least 1 method, whereas only half of them could be identified by all 3 methods. METamp can occur as focal amplification or polysomy. Our study revealed that the inconsistency between next-generation sequencing and FISH primarily occurred in the polysomy subtype. Further investigations indicated that compared with polysomy, focal amplification correlated with fewer co-occurring driver mutations, higher protein expressions of c-MET and phospho-MET, and higher incidence in acquired resistance than in de novo setting. Moreover, patients with focal amplification presented a more robust response to MET inhibitors compared with those with polysomy. Notably, a strong correlation was observed between focal amplification and programmed cell death ligand-1 expression, indicating potential therapeutic implications with combined MET inhibitor and immunotherapy for patients with both alterations. Our findings provide insights into the molecular complexity and clinical relevance of METamp in lung cancer, highlighting the role of MET focal amplification as an oncogenic driver and its feasibility as a primary biomarker to further investigate the clinical activity of MET inhibitors in future studies.

Abstract
Objective: To explore the clinical epidemiological characteristics of respiratory syncytial virus in children in Hubei Province from 2020 to 2023. Method: A single-center and cross-sectional study was used to analyze the clinical data of 3 271 children with respiratory syncytial virus infection in Wuhan Children's Hospital affiliated to Huazhong University of Science and Technology from July 1, 2020 to June 30, 2023. Nonparametric rank sum test and χ2 test were used for comparative analysis. Results: From July 1, 2020 to June 30, 2023, a total of 25 583 children were included in the analysis, of which 3 271(12.8%) children infected RSV. The detection rate was 16.3% in 2020-2021, 14.7% in 2021-2022 and 9.1% in 2022-2023. The detection rate decreased year by year (χ2=222.054, P<0.05). From 2020 to 2023, there was an anti-seasonal epidemic of RSV in spring and autumn. The detection rate of RSV in infants under 1 year old was the highest, but the median ages of RSV positive children increased (H=140.575, P<0.05). Pneumonia was the main clinical manifestation of RSV respiratory tract infection. Conclusion: The epidemiological characteristics of RSV in children in Hubei Province were different from those before. From 2020 to 2023, the detection rate of RSV decreased year by year. Besides winter, the prevalence of RSV could also be seen in spring and autumn. The median age of children infected with RSV increased after the epidemic. Pneumonia was the main clinical manifestation after RSV infection.

Abstract
As opposed to natural photosynthesis, a significant challenge in a semiconductor-based photocatalyst is the limited hole extraction efficiency, which adversely affects solar-to-fuel efficiency. Recent studies have demonstrated that photocatalysts featuring spatially isolated dual catalytic oxidation/reduction sites can yield enhanced hole extraction efficiencies. However, the decay dynamics of excited states in such photocatalysts have not been explored. Here a ternary barbell-shaped CdS/MoS2 /Cu2 S heterostructure is prepared, comprising CdS nanorods (NRs) interfaced with MoS2 nanosheets at both ends and Cu2 S nanoparticles on the sidewall. By using transient absorption (TA) spectra, highly efficient charge separation within the CdS/MoS2 /Cu2 S heterostructure are identified. This is achieved through directed electron transfer to the MoS2 tips at a rate constant of >8.3 × 109 s-1 and rapid hole transfer to the Cu2 S nanoparticles on the sidewall at a rate of >6.1 × 1010 s-1 , leading to an exceptional overall charge transfer constant of 2.3 × 1011 s-1 in CdS/MoS2 /Cu2 S. The enhanced hole transfer efficiency results in a remarkably prolonged charge-separated state, facilitating efficient electron accumulation within the MoS2 tips. Consequently, the ternary CdS/MoS2 /Cu2 S heterostructure demonstrates a 22-fold enhancement in visible-light-driven H2 generation compare to pure CdS nanorods. This work highlights the significance of efficient hole extraction in enhancing the solar-to-H2 performance of semiconductor-based heterostructure.

Abstract
BACKGROUND Sodium-glucose co-transporter-2 (SGLT2) inhibitors reduce progression of chronic kidney disease and the risk of cardiovascular morbidity and mortality in a wide range of patients. However, their effects on kidney disease progression in some patients with chronic kidney disease are unclear because few clinical kidney outcomes occurred among such patients in the completed trials. In particular, some guidelines stratify their level of recommendation about who should be treated with SGLT2 inhibitors based on diabetes status and albuminuria. We aimed to assess the effects of empagliflozin on progression of chronic kidney disease both overall and among specific types of participants in the EMPA-KIDNEY trial. METHODS EMPA-KIDNEY, a randomised, controlled, phase 3 trial, was conducted at 241 centres in eight countries (Canada, China, Germany, Italy, Japan, Malaysia, the UK, and the USA), and included individuals aged 18 years or older with an estimated glomerular filtration rate (eGFR) of 20 to less than 45 mL/min per 1·73 m2, or with an eGFR of 45 to less than 90 mL/min per 1·73 m2 with a urinary albumin-to-creatinine ratio (uACR) of 200 mg/g or higher. We explored the effects of 10 mg oral empagliflozin once daily versus placebo on the annualised rate of change in estimated glomerular filtration rate (eGFR slope), a tertiary outcome. We studied the acute slope (from randomisation to 2 months) and chronic slope (from 2 months onwards) separately, using shared parameter models to estimate the latter. Analyses were done in all randomly assigned participants by intention to treat. EMPA-KIDNEY is registered at ClinicalTrials.gov, NCT03594110. FINDINGS Between May 15, 2019, and April 16, 2021, 6609 participants were randomly assigned and then followed up for a median of 2·0 years (IQR 1·5-2·4). Prespecified subgroups of eGFR included 2282 (34·5%) participants with an eGFR of less than 30 mL/min per 1·73 m2, 2928 (44·3%) with an eGFR of 30 to less than 45 mL/min per 1·73 m2, and 1399 (21·2%) with an eGFR 45 mL/min per 1·73 m2 or higher. Prespecified subgroups of uACR included 1328 (20·1%) with a uACR of less than 30 mg/g, 1864 (28·2%) with a uACR of 30 to 300 mg/g, and 3417 (51·7%) with a uACR of more than 300 mg/g. Overall, allocation to empagliflozin caused an acute 2·12 mL/min per 1·73 m2 (95% CI 1·83-2·41) reduction in eGFR, equivalent to a 6% (5-6) dip in the first 2 months. After this, it halved the chronic slope from -2·75 to -1·37 mL/min per 1·73 m2 per year (relative difference 50%, 95% CI 42-58). The absolute and relative benefits of empagliflozin on the magnitude of the chronic slope varied significantly depending on diabetes status and baseline levels of eGFR and uACR. In particular, the absolute difference in chronic slopes was lower in patients with lower baseline uACR, but because this group progressed more slowly than those with higher uACR, this translated to a larger relative difference in chronic slopes in this group (86% [36-136] reduction in the chronic slope among those with baseline uACR <30 mg/g compared with a 29% [19-38] reduction for those with baseline uACR ≥2000 mg/g; ptrend<0·0001). INTERPRETATION Empagliflozin slowed the rate of progression of chronic kidney disease among all types of participant in the EMPA-KIDNEY trial, including those with little albuminuria. Albuminuria alone should not be used to determine whether to treat with an SGLT2 inhibitor. FUNDING Boehringer Ingelheim and Eli Lilly.

Abstract
BACKGROUND The EMPA-KIDNEY trial showed that empagliflozin reduced the risk of the primary composite outcome of kidney disease progression or cardiovascular death in patients with chronic kidney disease mainly through slowing progression. We aimed to assess how effects of empagliflozin might differ by primary kidney disease across its broad population. METHODS EMPA-KIDNEY, a randomised, controlled, phase 3 trial, was conducted at 241 centres in eight countries (Canada, China, Germany, Italy, Japan, Malaysia, the UK, and the USA). Patients were eligible if their estimated glomerular filtration rate (eGFR) was 20 to less than 45 mL/min per 1·73 m2, or 45 to less than 90 mL/min per 1·73 m2 with a urinary albumin-to-creatinine ratio (uACR) of 200 mg/g or higher at screening. They were randomly assigned (1:1) to 10 mg oral empagliflozin once daily or matching placebo. Effects on kidney disease progression (defined as a sustained ≥40% eGFR decline from randomisation, end-stage kidney disease, a sustained eGFR below 10 mL/min per 1·73 m2, or death from kidney failure) were assessed using prespecified Cox models, and eGFR slope analyses used shared parameter models. Subgroup comparisons were performed by including relevant interaction terms in models. EMPA-KIDNEY is registered with ClinicalTrials.gov, NCT03594110. FINDINGS Between May 15, 2019, and April 16, 2021, 6609 participants were randomly assigned and followed up for a median of 2·0 years (IQR 1·5-2·4). Prespecified subgroupings by primary kidney disease included 2057 (31·1%) participants with diabetic kidney disease, 1669 (25·3%) with glomerular disease, 1445 (21·9%) with hypertensive or renovascular disease, and 1438 (21·8%) with other or unknown causes. Kidney disease progression occurred in 384 (11·6%) of 3304 patients in the empagliflozin group and 504 (15·2%) of 3305 patients in the placebo group (hazard ratio 0·71 [95% CI 0·62-0·81]), with no evidence that the relative effect size varied significantly by primary kidney disease (pheterogeneity=0·62). The between-group difference in chronic eGFR slopes (ie, from 2 months to final follow-up) was 1·37 mL/min per 1·73 m2 per year (95% CI 1·16-1·59), representing a 50% (42-58) reduction in the rate of chronic eGFR decline. This relative effect of empagliflozin on chronic eGFR slope was similar in analyses by different primary kidney diseases, including in explorations by type of glomerular disease and diabetes (p values for heterogeneity all >0·1). INTERPRETATION In a broad range of patients with chronic kidney disease at risk of progression, including a wide range of non-diabetic causes of chronic kidney disease, empagliflozin reduced risk of kidney disease progression. Relative effect sizes were broadly similar irrespective of the cause of primary kidney disease, suggesting that SGLT2 inhibitors should be part of a standard of care to minimise risk of kidney failure in chronic kidney disease.

Abstract
OBJECTIVE Brainstem tumors present a significant challenge in surgical treatment, and the prognostic factors in children are lacking. This study aimed to investigate clinical characteristics and prognostic factors of surgical treatment in children with brainstem tumors. PATIENTS AND METHODS 50 children with brainstem tumors who underwent surgical treatment, including frameless- or frame-based stereotactic biopsy and resection, were included and followed up for clinical and biological analysis. Factors of outcomes were assessed by univariate and multivariate analysis. RESULTS 27 cases (54.0%) underwent resection in all children with brainstem tumors. The rate of resection reached as high as 81.8% in children with non-diffuse intrinsic pontine glioma (DIPG), while in children with DIPG, biopsy was performed in the majority, and resection was obtained in the minority with focal necrosis. A rare complication was found following the surgery. Multivariate analysis considered World Health Organization (WHO) grade 3-4, with hazard ratio (HR)=4.48, 95% confidence interval (CI) of 2.84-8.69, p=0.001, H3K27M mutation (HR=2.50, 95% CI 1.73-5.69, p=0.015), and hydrocephalus (HR=2.17, 95% CI 1.08-5.32, p=0.014) as independent adverse prognostic factors. For Kaplan-Meier analysis, children with WHO grade 3-4, Ki-67 LI ≥ 20%, TP53 mutation, H3K27M mutation, DIPG, and hydrocephalus had significantly decreased overall survival (OS). CONCLUSIONS A high rate of resection has been obtained in non-DIPG, and surgical intervention is remarkably safe and efficient for children with brainstem tumors. WHO grade 3-4, H3K27M mutation, and hydrocephalus indicate poor prognosis in children with brainstem tumors.

Abstract
Clinical outcomes of colon adenocarcinoma (COAD) exhibit heterogeneity among different patients, highlighting the need for novel prognostic biomarkers. Kinesin superfamily members have been shown to play a crucial role in tumors and can predict cancer diagnosis and prognosis. However, the role of kinesin family member C2 (KIFC2) in tumors, particularly its prognostic value in COAD, remains poorly understood. Our bioinformatics analysis of the cancer genome atlas and GEO databases revealed significantly higher expression of KIFC2 in COAD, correlating with a worse prognosis in the cancer genome atlas-COAD and GSE17536 cohorts. Additionally, differentially expressed genes in COAD were enriched in immune-related pathways, and patients with higher KIFC2 expression showed fewer activated CD4 + T cells. These findings suggest KIFC2 as a potential prognostic biomarker for COAD, warranting further validation in clinical studies.

Abstract
BACKGROUND The aim of this study was to explore the safety and efficacy of a novel mini-open sublay hernioplasty with D10 mesh for primary lumbar hernias. METHODS This retrospective study included 48 patients with primary lumbar hernias who underwent mini-open sublay hernioplasty with D10 mesh from January 2015 to January 2022 in our hospital. Observation indicators were intraoperative measured diameter of hernia ring defect, operation time, length of hospital stay, postoperative follow-up, complications, postoperative visual analog scale (VAS) score, chronic pain. RESULTS The operations were completed successfully in all 48 cases. The mean diameter of hernia ring was 2.66 ± 0.57 cm (range 1.5-3.0 cm), the mean operation time was 41.54 ± 13.21 min (range 25-70 min), the intraoperative blood loss was 9.89 ± 6.16 ml (range 5-30 ml), and the mean hospital stay was 3.14 ± 1.53 days (range 1-6 days). The mean preoperative and postoperative VAS scores at 24 h were 0.29 ± 0.53 (range 0-2) and 2.52 ± 0.61 (range 2-6), respectively. All cases were followed-up for 53.4 ± 24.3 months (range 12-96 months) without seroma, hematoma, incision or mesh infection, recurrence, and obvious chronic pain. CONCLUSION A novel mini-open sublay hernioplasty with D10 mesh for primary lumbar hernias is safe and feasible. Its efficacy in the short term is favorable.

Abstract
Objective: To analyze the imaging features of cone-beam CT (CBCT) of ameloblastoma (AB), odontogenic keratocyst (OKC) and dentigerous cysts (DC) associated with the mandibular impacted third molars,so as to provide useful information for differential diagnosis of these lesions. Methods: The patients who were with complete clinical data, pathological diagnosis and CBCT images from AB, OKC and DC around the mandibular impacted third molars were collected in Peking University Hospital of Stomatology from August 2016 to December 2021. A total of 109 patients (14 were diagnosed as AB, 23 were diagnosed as OKC and the others were diagnosed as dental cysts) were collected, including 73 males and 36 females. The age ranged from 11 to 70. The analyzed imaging features included location and internal density of the lesions, bone expansion, root resorption of adjacent teeth and types of the impacted teeth. The Chi square test was used to compare the gender of different lesions, and the Fisher's exact test was used to compare imaging features of lesions. When P<0.05, there was a significant difference among the three. Logistic regression analysis was performed to determine the imaging features that significantly contribute to correct imaging diagnosis. Corresponding P-values were calculated for all factors from multivariate models. Results: In the 23 cases of OKC, no special location was observed for the center of the lesion, heterogeneous high-density were seen in 21.7% of the cases, 56.5% of the cases had no significant bone expansion and the impacted teeth were not specially oriented. Among the 14 AB, 7 cases (7/14) were mainly located in the ramus of the mandible, and all cases (14/14) had buccal/lingual expansion of the jaw, 8 cases (8/14) presented root resorption of the adjacent teeth, and mesial impacted mandibular third molar were seen in 6 cases (6/14). Among the 72 DC, 88.9% (64/72) of the cases were mainly limited to the crown of the impacted third molar, 72.2% (52/72) of the cases had no obvious bone expansion, inverted impacted teeth were shown in 56.9% (41/72) of the cases. There was a significant difference among the three groups (χ2=7.30, P=0.026) in gender. AB and odontogenic cyst were more common in men than in women, while the incidence of OKC was roughly equal between men and women.There were significant differences in the location (P<0.001), internal density (P=0.001) of the lesions, bone expansion (P<0.001) and types of the impacted teeth (P<0.001), while no statistical difference was found for root resorption of adjacent teeth (P=0.153). Logistics regression analysis showed that the location of the lesion, internal density, bone expansion, root resorption of adjacent teeth and the types of impacted teeth had significant effects on the accurate diagnosis of the three kinds of lesions. Conclusions: Location, internal density, bone expansion and types of the impacted teeth played an important role in the correct imaging diagnosis. Further analysis indicates that when the classification of impacted teeth and the location of lesions are considered synchronously, DC can be differentiated from AB and OKC.

Abstract
Semiconductor photodetectors, as photoelectric devices using optical-electrical signal conversion for detection, are widely used in various fields such as optical communication, medical imaging, environmental monitoring, military tracking, remote sensing, etc. Compared to the conventional photodetector materials including silicon, III-V semiconductors and metal sulfides, graphitic carbon nitride (g-C3N4) as a metal-free polymeric semiconductor, has many advantages such as low-price, easy preparation, efficient visible light response, and relatively good thermal stability. In the meantime, the polymer characteristics also endow the g-C3N4 with good mechanical properties. Apart from being used for photo(electro)catalysts during the past decades, the potential use of g-C3N4 in photodetectors has attracted great research interests very recently. In this review, we first briefly introduce the structure and properties of g-C3N4 and the key performance parameters of photodetectors. Then, combining the very recent progress, the review focuses on the active materials, fabrication methods and performance enhancement strategies for g-C3N4 based photodetectors. The existing challenges are discussed and the future development of g-C3N4 based photodetectors is also forecasted.

Abstract
Semiconductor-based heterostructures have exhibited great promise as a photocatalyst to convert solar energy into sustainable chemical fuels, however, their solar-to-fuel efficiency is largely restricted by insufficient interfacial charge separation and limited catalytically active sites. Here the integration of high-efficiency interfacial charge separation and sufficient single-atom metal active sites in a 2D van der Waals (vdW) heterostructure between ultrathin polymeric carbon nitride (p-CN) and Ni-containing Salphen-based covalent organic framework (Ni-COF) nanosheets is illustrated. The results reveal a NiN2 O2 chemical bonding in NiCOF nanosheets, leading to a highly separated single-atom Ni sites, which will function as the catalytically active sites to boost solar fuel production, as confirmed by X-ray absorption spectra and density functional theory calculations. Using ultrafast femtosecond transient adsorption (fs-TA) spectra, it shows that the vdW p-CN/Ni-COF heterostructure exhibits a faster decay lifetime of the exciton annihilation (τ = 18.3 ps) compared to that of neat p-CN (32.6 ps), illustrating an efficiently accelerated electron transfer across the vdW heterointerface from p-CN to Ni-COF, which thus allows more active electrons available to participate in the subsequent reduction reactions. The photocatalytic results offer a chemical fuel generation rate of 2.29 mmol g-1 h-1 for H2 and 6.2 µmol g-1 h-1 for CO, ≈127 and three times higher than that of neat p-CN, respectively. This work provides new insights into the construction of a π-conjugated vdW heterostructure on promoting interfacial charge separation for high-efficiency photocatalysis.

Abstract
Cruznema velatum isolated from soil in a chestnut orchard located at Guangdong province, China, is redescribed with morphology, molecular barcoding sequences, and transcriptome data. The morphological comparison for C. velatum and six other valid species is provided. Phylogeny analysis suggests genus Cruznema is monophyletic. The species is amphimix, can be cultured with Escherichia coli in 7-9 days from egg to egg-laying adult, and has a lifespan of 11 to 14 days at 20°C. The transcription data generated 45,366 unigenes; 29.9%, 31.3%, 24.8%, and 18.6% of unigenes were annotated in KOG, SwissProt, GO, and KEGG, respectively. Further gene function analysis demonstrated that C. velatum share the same riboflavin, lipoic acid, and vitamin B6 metabolic pathways with Caenorhabditis elegans and Pristionchus pacificus.

Abstract
The relatively short-lived excited states, such as the nascent electron-hole pairs (excitons) and the shallow trapping states, in semiconductor-based photocatalysts produce an exceptionally high charge carrier recombination rate, dominating a low solar-to-fuel performance. Here, a π-conjugated in-plane heterostructure between graphitic carbon nitride (g-CN) and carbon rings (Crings ) (labeling g-CN/Crings ) is effectively synthesized from the thermolysis of melamine-citric acid aggregates via a microwave-assisted heating process. The g-CN/Crings in-plane heterostructure shows remarkably suppressed excited-state decay and increased charge carrier population in photocatalysis. Kinetics analysis from the femtosecond time-resolved transient absorption spectroscopy illustrates that the g-CN/Crings π-conjugated heterostructure produces slower exciton annihilation (τ1 = 7.9 ps) and longer shallow electron trapping (τ2 = 407.1 ps) than pristine g-CN (τ1 = 3.6 ps, τ2 = 264.1 ps) owing to Crings incorporation, both of which enable more photoinduced electrons to participate in the photocatalytic reactions, thereby realizing photoactivity enhancement. As a result, the photocatalytic activity exhibits an eightfold enhancement in visible-light-driven H2 generation. This work provides a viable route of constructing π-conjugated in-plane heterostructures to suppress the excited-state decay and improve the photocatalytic performance.

Abstract
Abstract
Background: MET amplification (METamp) occurs in 1-5% of treatment-naïve or 5-20% of epidermal growth factor receptor tyrosine kinase inhibitors-treated lung cancers (LC). It is a promising therapeutic target in LC. Although fluorescence in situ hybridization (FISH), next-generation sequencing (NGS), and immunohistochemical staining (IHC) are available for METamp detection, but the most appropriate detection method and criteria for defining METamp are uncertain. Here, we explored the concordance of these three methods in informing METamp status and identified patients likely to benefit from MET inhibitors.
Methods: Tissue samples from LC patients who underwent MET detection by FISH, NGS, and IHC tests at Shanghai Chest Hospital were retrospectively collected. MET focal amplification and polysomy by FISH were determined as MET/CEP7 ratio ≥ 2, and < 2 with the average MET signals per cell ≥ 5, respectively. NGS-based MET focal amplification and polysomy were determined with in-house scripts (Burning Rock Biotech). Focal amplification and polysomy were defined as METamp-positive. IHC-based MET positive was determined with H-score ≥ 200. FISH was used as a reference.
Results: A total of 231 patients with a median age of 65 years were enrolled. With FISH as reference testing, NGS detection for METamp showed 66.9% (87/130) sensitivity and 95.1% sensitivity (96/101), and IHC had 71.5% (93/130) sensitivity and 91.1% (92/101) specificity. Furthermore, NGS detection for MET focal amplification achieved 87.2% (75/86) sensitivity and 96.6% (140/145) specificity, while MET polysomy detection showed 20.5% (9/44) sensitivity and 98.4% (184/187) specificity. Of 153 treatment-naïve patients, patients with focal amplification (FISH: 16.7%; NGS: 16.3%) had a significantly lower frequency of classic LC oncogene alterations than those with polysomy (FISH: 51.6%, p = 0.001; NGS: 58.3%, p = 0.006) and METamp-negative patients (METneg; FISH: 72.1%, p < 0.001; NGS: 64.1%, p < 0.001). A total of 27 patients had follow-up data. The disease control rate (DCR) to MET inhibitors was 73.1% (19/26) for overall METamp, 81.0% (17/21) for focal amplification, and 40.0% (2/5) for polysomy using FISH results. In contrast, corresponding DCRs using NGS results were 84.2% (16/19), 88.9% (16/18), and 0% (0/1), respectively. Moreover, patients with NGS-based focal amplification had a significantly longer progression-free survival (PFS) than those with polysomy or METneg. Of note, 1 patient with METneg by FISH was determined to harbor focal amplification by NGS and achieved partial response to crizotinib with a PFS of 314 days.
Conclusion: Our results suggest that MET focal amplification leads to oncogenic MET addiction and is associated with promising efficacy of MET inhibitors. MET focal amplification by NGS tests might be a feasible and powerful biomarker to identify LC patients who benefit from MET inhibitors.

Abstract
The clinical outcome of resectable non-small cell lung cancer (NSCLC) patients receiving neoadjuvant chemoimmunotherapy was great but varies greatly. Meanwhile, the pathological response after neoadjuvant chemoimmunotherapy is significantly associated with survival outcomes. The aim of this retrospective study was to identify which population of patients with locally advanced and oligometastatic NSCLC have favorable pathological response after neoadjuvant chemoimmunotherapy. NSCLC patients treated with neoadjuvant chemoimmunotherapy were enrolled between February 2018 and April 2022. Data on clinicopathological features were collected and evaluated. Multiplex immunofluorescence was performed on pre-treatment puncture specimens and surgically resected specimens. A total of 29 patients with stage III and IV locally advanced or oligometastatic NSCLC who received neoadjuvant chemoimmunotherapy and R0 resection were enrolled. The results showed that 55% (16/29) of patients had major pathological response (MPR) and 41% (12/29) of patients had complete pathological response (pCR). In stroma area of pre-treatment specimen, the higher infiltration of CD3+ , PD-L1+ tumor infiltrating lymphocytes (TILs) and the lower infiltration of CD4+ and CD4+ FOXP3+ TILs were more likely to appear in patients with pCR. However, in tumor area, the higher infiltration of CD8+ TILs were more likely to appear in patients with non-MPR. In post-treatment specimen, we found increased infiltration of CD3+ CD8+ , CD8+ GZMB+ and CD8+ CD69+ TILs and decreased infiltration of PD-1+ TILs both in stroma and tumor area. Neoadjuvant chemoimmunotherapy achieved a MPR rate of 55% and induced greater immune infiltration. Besides, we observed that the baseline TILs and its spatial distribution correlates to pathological response.

Abstract
BACKGROUND Plasma and tissue biopsy have both used for targeting actionable driver gene mutations in lung cancer, whose concordance is imperfect. A reliable method to predict the concordance is urgently needed to ease clinical application. METHODS A total of 1012 plasma samples, including 519 with paired-tissue biopsy samples, derived from lung adenocarcinoma patients were retrospectively enrolled. We assessed the associations of several clinicopathological characteristics and serum tumor markers with the concordance between plasma and tissue biopsies. RESULTS When carcinoembryonic antigen (CEA) levels were higher than thresholds of 15.01 ng/ml and 51.15 ng/ml, the positive predictive value of concordance reached 90% and 95%, respectively. When CEA levels were lower than thresholds of 5.19 ng/ml and 3.26 ng/mL, the negative predictive value of concordance reached 45% and 50%. The performance of CYFRA21-1 in predicting concordance was similar but inferior to CEA (AUC: 0.727 vs. 0.741, p = 0.633). The performance of CEA combined with CYFRA21-1 in predicting the concordance was similar to that of the combination of independent factors derived from the LASSO regression model (AUC: 0.796 vs. 0.818, p = 0.067). CEA (r = 0.47, p < 0.01) and CYFRA21-1 levels (r = 0.45, p < 0.05) were significantly correlated with the maximum variant allele frequency, respectively. CONCLUSIONS CEA combined with CYFRA21-1 could effectively predict the concordance between plasma and tissue biopsies, which could be used for evaluating the priority of plasma and tissue biopsies for gene testing to timely guide clinical applications in advanced lung adenocarcinoma patients.

Abstract
OBJECTIVE Aside from the severity, surgical interventions for the treatment of neurological dysfunctions remain controversial. This study aimed to find factors predicting the benefits of tethered cord syndrome (TCS) surgery. PATIENTS AND METHODS 80 children with TCS were included and followed up for pre- and post-operative factors along with neurophysiological analysis. Outcomes were assessed by univariate and multivariate analysis. RESULTS Surgical treatment not only improved preoperative signs and symptoms in 79% of TCS patients but it showed to be an efficient procedure for the occurrence of future neurological defects. Univariate analysis also revealed that surgical intervention in TCS children (age <1 year) can modulate filar lipoma location and cutaneous abnormalities three months after surgery. Neurophysiological assessment revealed only 5.0% of surgical complications in TCS patients. Two patients had cerebrospinal fluid leakage, and two cases of CNS infection were detected. CONCLUSIONS Surgical intervention is highly recommended for the prevention of neurological deficits in children with TCS. Electrophysiological monitoring revealed rare complications following the surgery.

Abstract
Electrooxidation reactions of organic molecules that require a much lower overpotential are currently considered as promising alternatives to replace the oxygen evolution reaction (OER) in water electrolysis. Herein, an ultrafast oxygen plasma treatment is implemented to modify commercial cobalt-nickel foam (CNF) to regulate the high-valence Co3+ and Ni3+, rendering more active sites, faster reaction kinetics and enhanced response towards glucose. Compared to the OER, the overpotential of the plasma-treated CNF at 10 mA cm-2 was reduced to 133 mV via glucose electro-oxidation coupled with water splitting.

Abstract
RATIONALE Membranous nephropathy (MN) is an autoimmune disease, which is classified into primary and secondary MN. Malignancy-associated MN (M-MN) accounts for about 10% of secondary MN cases. Lung cancer is the most common type of malignancy among M-MN patients. Immune checkpoint inhibitors (ICIs) targeting programmed cell death-1 (PD-1) or programmed cell death ligand-1 (PD-L1) have showed promising efficacy and good safety in many types of solid tumors, including non-small cell lung cancer. To date, whether ICIs could be a treatment option for M-MN patients with PD-L1 expression and or high tumor mutation burden (TMB) level has not been documented. PATIENT CONCERNS A 68-year-old male patient presented with edema of the lower limbs with increased urine foam in August 2018. Biopsy on the right kidney showed MN at stage I with subepithelially localized immune deposits. DIAGNOSIS Lung squamous cell carcinoma (LSCC)-associated MN with PD-L1 expression (20%) and high TMB level (26.2 mutations/Mb). INTERVENTIONS The patient received immunosuppressive therapy targeting the initially diagnosed primary MN as first-line treatment plus surgery and radiochemotherapy following pembrolizumab targeting the definitively diagnosed lung cancer as second-line treatment. OUTCOMES The patient benefited from radiochemotherapy following pembrolizumab (lasting more than 38 months) rather than immunosuppressive therapy. LESSONS Our work suggests that combined ICIs might be an effective treatment option for M-MN patients who harbor PD-L1 expression. Our work highlights that the presence of malignancy should not be neglected at the initial diagnosis of MN.

Abstract
BACKGROUND Colon adenocarcinoma (COAD) is a globally prevalent cancer, with hormone secretion playing a crucial role in its progression. Despite this, there is limited understanding of the impact of hormone secretion on COAD prognosis. This study aimed to establish a prognostic signature based on hormone secretion-related genes and to elucidate the potential functional mechanisms of these genes in COAD. METHODS Using data from The Cancer Genome Atlas COAD cohort (TCGA-COAD), six hormone secretion-related genes were identified (CYP19A1, FOXD1, GRP, INHBB, SPP1, and UCN). These genes were used to develop a Hormone secretion score (HSS), which was then evaluated using the Kaplan-Meier curve and multivariable Cox analysis. The HSS model was further validated with external GEO cohorts (GSE41258, GSE39582, and GSE87211). Functional enrichment analyses were performed, and the CIBERSORT and TIDE algorithms were used to assess tumor infiltration. RESULTS The study developed a prognostic signature, dividing patients into HSS-high and HSS-low groups. The HSS-high group showed a notably worse prognosis within the TCGA-COAD dataset and in three independent datasets: GSE41258, GSE39582, and GSE87211. Moreover, the HSS-high group predicted a shorter overall survival rate in patients maintaining microsatellite stability (MSS). The functional analysis associated HSS-high with the hypoxic, epithelial-mesenchymal transition (EMT), and TGF-β signaling pathways and correlated with distant and lymph node metastases. The tumor immune microenvironment analysis revealed an elevated CIBERSORT score in the HSS-high group, suggesting an association with tumor metastasis. Further, the HSS-high group showed a higher TIDE score, indicating that patients with high HSS scores are less likely to benefit from Immune Checkpoint Inhibitor (ICI) therapy. CONCLUSIONS This study demonstrated the prognostic significance of a HSS signature based on six hormone secretion-related genes in COAD. The findings suggest that this gene signature may serve as a reliable biomarker for predicting survival outcomes in COAD patients.

Abstract
Abstract
Background
30-day rehospitalisation following heart event among acute coronary syndrome (ACS) patients remains high and is largely contributed by poor disease-related knowledge and self-management, especially in the disadvantaged patient groups such as those with low education levels and inadequate health literacy. Traditional patient education methods fail to address these issues.
Purpose
This study aimed to test a unique consumer co-designed discharge education application (app) on patients' knowledge and its acceptability.
Methods
ACS patients (unstable angina, non-STEMI or STEMI) were recruited from Royal Adelaide Hospital at South Australia during admission, provided with the app via tablet for one-month self-delivered education. The app has undergone a rigorous development process with the substantial engagement of consumers (Figure 1). App content includes the Heart Foundation Six Steps to Cardiac Recovery including disease-related knowledge, risk factor management, and ACS responses, assessed at baseline, followed by first use at discharge and one month later. Patients and cardiac nurses rated the acceptability of the app.
Results
Among 22 Participants 81.8% were male (n=18), with a mean age of 59.7 (10.3) years, 45.5% (n=10) had not completed high school and nearly a quarter of the participants had marginal or below marginal health literacy. The diagnosis included STEMI (n=16, 72.7%) and non-STEMI (n=5, 22.7%). The majority of participants underwent percutaneous coronary intervention (PCI) (n=21, 95.5%)
Significant improvements were observed for overall coronary artery disease knowledge at one month (p=0.003) and the exercise and nutrition domains at discharge (p=0.029; p<0.001) and one month (p=0.02; p=0.003) (Figure 2). Significant improvements were also observed for ACS knowledge and beliefs at discharge (p=0.008; p=0.038) and one month (p<0.001; p=0.025) when ACS response attitude was also significantly improved at one month (p=0.036). Overall acceptability was high at 7.7/10 (n=22 nurses) and 8.3/10 (patients). The participants described the app as `clear, simple, easy to understand, as well as stimulating and interactive, better than a live person'.
Conclusion
This novel, self-delivered Avatar-based ACS discharge education App has the potential to provide discharge education for ACS patients even for those who have low education levels or inadequate health literacy. Results need to be confirmed in a randomised controlled trial.

Background/significance
The rapid development of information technology is driving the evolution of choices of modes of delivery of healthcare services. The internet is an extremely powerful tool for accessing information, and communication. However, involvement of patients in the assessment of such an intervention is crucial, and can be achieved through a person-centred approach, utilising a co-design process with the aim to increase intervention usability.
Purpose
To assess the usability of the Country Access to Cardiac Health (CATCH) Web, an interactive web application for cardiac rehabilitation (CR), co-designed with rural and remote Australians, following the co-design development phase.
Methods
The User Experience (UX) Design framework was used to co-design the web portal with CR patients through two rounds of six co-design workshops pre (n=39), and post (n=35). Participants and family members living in rural and remote areas of Australia were invited to participate based on their eligibility for CR as outlined by the National Heart Foundation of Australia. As part of the UX Design Framework the System Usability Scale (SUS) was used to measure objective feedback from participants on the website design. The SUS assesses the three core components of a products usability: effectiveness, efficiency and satisfaction using a 10 question Likert scale. Mean scores were compared between the two rounds of workshops using an independent T-Test. The mean SUS score is categorised into poor to moderate (<68), good (68-80.3) and excellent (>=80.3) and categories were compared between the two rounds of workshops through Chi-Square tests.
Results
The 35 participants in the usability workshops had a mean age of 68.6 (SD 11.2) years and 16 (47%) were female (Table 1). The majority had experienced a myocardial infarction (15, 42.8%) and had hyperlipidemia (17, 50%), heart failure (15, 44%), hypertension (14, 41%), and Type II diabetes (7, 21%). Of these participants 20 (59%) used a smart phone, 18 (58%) had access to the National Broadband Network and 20 (59%) engaged with Facebook. From the first to the second round of workshops, there was an improvement in the mean SUS scores from 66.7 (SD16.8) to 73.6 (SD 21.0); p=0.26. The proportion of participants rating it as good or excellent increased from 48.7 to 65.8%; p=0.11 (Figure1).
Conclusion
The usability testing of the interactive CATCH web application showed an improvement in the SUS rating from poor to moderate in the co-design development phase to good or excellent by most of the participants in the usability testing phase. Usability is closely related to engagement with a digital health intervention. Upcoming evaluation of this intervention will report on clinical outcomes.

Abstract
BACKGROUND There has been a rapid increase in the number of human adenovirus type 7 (HAdV-7) and invasive pulmonary fungal infections (IPFIs) co-infection. METHODS In this study, we included patients with confirmed HAdV-7 infection during the period from 2018 to 2019 to explore clinical characteristics of severe HAdV-7 pneumonia combined with IPFIs. RESULTS Among the 143 patients, 35 cases were co-infected with IPFIs. Others were assigned to the control group (n Z 108). Patients wereprone to be complicated with respiratory failure, heart failure and hemophagocytic syndromein IPFIs group. Thirty-one species of fungi were detected in the IPFIs group, among whichAspergillus was the most common species. Compared to control group, patients had lowerlevels of WBC, CD3þ T lymphocyte counts and CD19þ B lymphocyte counts in IPFIs group. CONCLUSION Aspergillus is the most common species in IPFIs combined with severe HAdV-7 pneumonia. For children with severe HAdV-7 pneumonia who are younger, have a long course of disease, and have been admitted to the ICU, we should predict the occurrence of IPFIs when there is multi-system dysfunction and the reduction of CD3+ T lymphocyte counts and CD19+ B lymphocyte counts in course of their disease.

Abstract
Background Acquired resistance is inevitable in non-small cell lung cancer (NSCLC) patients treated with epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs). The emergence of EGFR exon 20 C797S is one of the major resistance mechanisms to osimertinib as a third-generation EGFR-TKI. To date, there is no standard of care for NSCLC patients after acquiring EGFR C797S. Immune checkpoint inhibitors (ICIs) have revolutionized the treatment of various types of cancers in the last decade. Whether NSCLC patients with acquired EGFR C797S could benefit from ICIs remains elusive. Case Description Herein, we reported two cases of EGFR-mutant NSCLC patients who acquired a tertiary EGFR mutation C797S benefited from ICIs. A 28-year-old woman presented with anepithymia and nausea. Chest computed tomography (CT) revealed a mass in the right lung. She was diagnosed with stage IV lung adenocarcinoma (LUAD) with EGFR exon 19 deletion (19del) based on imaging and next-generation sequencing (NGS) findings. She received icotinib followed by osimertinib, then acquired EGFR T790M-cis-C797S. She had low tumor mutation burden (TMB) and achieved partial response (PR) to a programmed cell death-1 (PD-1) inhibitor sintilimab combined with platinum-based doublet chemotherapy as late-line treatment lasting more than 5 months. A 66-year-old man complained with chest tightness, hemoptysis, and back pain. CT scans revealed a mass in the right lung and metastases to the bilateral lungs, liver, adrenal gland, mediastinal lymph nodes, and bone. He was also diagnosed with EGFR 19del-positive LUAD and treated with icotinib followed by osimertinib. He also acquired EGFR T790M-cis-C797S. The patient had low TMB also and benefited from a PD-1 inhibitor camrelizumab combined with platinum-based doublet chemotherapy as late-line treatment with a progression-free survival (PFS) of 8 months. Two cases had no treatment-related adverse events leading to discontinuation of PD-1 inhibitors. Conclusions Our study provides the first clinical evidence that ICIs combined with platinum-based doublet chemotherapy may be effective treatment options for overcoming resistance mediated by EGFR T790M-cis-C797S. Clinical trials are needed to evaluate the efficacy and safety of PD-1 inhibitors in the treatment of NSCLC patients harboring EGFR T790M-cis-C797S.

Abstract
Background:Bullous systemic lupus erythematosus (BSLE) is a rare subtype of systemic lupus erythematosus, accounting for less than 1% of systemic lupus erythematosus (SLE) [1]. It is common in adults aged 20 to 40, with female predominace [2]. Its skin manifestations are mainly tensive blisters, especially involving oral and genital mucosa, Nissl’s sign is mostly negative, blisters break and heal to form pigmentation of varying degrees, leaving no scar. At present, the main treatment is systemic application of corticosteroids combined with immunosuppressants. Here, we report a BSLE who successfully treated with mycophenolate mofetil (MMF) combined with glucocorticoid.ObjectivesTo be vigilant in the early identification of BSLE, and through the treatment experience of this case, it can provide a basis for the use of Mycophanol ester as the preferred drug for the treatment of BSLE in the future.MethodsThe clinical manifestation, laboratory test, treatment, and outcome were described.ResultsA 50-year-old female patient with systemic lupus erythematosus presented with wandering joint pain for 1 year and sporadic patchy erythema on eyelid, hands, and neck for 7 months. There are blisters on part of her erythema and normal skin, about 1mm-15mm in diameter, the blister fluid is cool, fusion is broken, and Nissl’s sign is negative. She suffered from anemia, albuminuria, polyserous effusion and other system damage. Skin histopathology showed mild hyperkeratosis of epidermis, formation of subepidermal blisters and accumulation of a large number of neutrophils; direct immunofluorescence showed that the positive expressions of IgA, IgG and C3 were found in the basement membrane of the skin, leading to a diagnosis of BSLE. In the initial stage, patients were treated with high-dose glucocorticoid (160 mg, qd) combined with immunosuppressants (thalidomide and hydroxychloroquine), but the number of blisters increased. After treatment with MMF (1 g, bid), the skin lesions disappeared, joint pain relieved, anemia was corrected, and polyserous effusion was absorbed. She was followed up for half a year and there was no recurrence.ConclusionPatients with BSLE are often accompanied by multiple system damage [2], so it is critical to correctly identify BSLE and provide appropriate treatment as soon as possible. For patients who do not respond to single glucocorticoid therapy, combined with MMF can be used as the preferred drug for the treatment of BSLE in the future.References:[1] L.

Abstract
BackgroundIguratimod (IGU), as one of the conventional synthetic disease-modifying antirheumatic drugs (csDMARDs), has been approved by National Medical Products Administration (NMPA) to treat Rheumatoid arthritis (RA).ObjectivesThis study aimed to compare the cost-effectiveness of well-established RA therapies using a claims-based algorithm in RA patients.MethodsAn electronic medical record (EMR) database from Zhujiang Hospital was utilized to estimate the cost-effectiveness of medication for RA patients, including IGU with MTX, biological DMARDs (bDMARDs) with MTX, and MTX alone for more than 6 months from 2014 to 2020. Patients who were deemed effective must meet all the following criteria according to the algorithm, high adherence; no bDMARDs or IGU switch or addition; no prescription of new csDMARDs; no increase in dose or frequency of index drug; no new use of chronic glucocorticoids or increase in glucocorticoid dose; and no more than one glucocorticoid injection. Average cost was calculated by summing total cost of effective treatment and dividing by number of patients achieving efficacy in each group.ResultsA total of 263 patients were included in the analysis. Based on a claims-based algorithm, the effective rate was 27.1 % (26/96) for IGU with MTX group, 11.2% (7/62) for bDMARDs with MTX group, and 13.3% (14/105) for MTX alone group, respectively. Average cost of effective treatment was $833.46 for IGU with MTX therapy, $2554.57 for bDMARDs with MTX therapy, and $171.48 for MTX alone (Table 1).Table 1.Effectiveness and Cost per Effectively Treated Patient with RACriteriaAll patients (n=263)IGU with MTX group(n=96)bDMARDs with MTX group (n=62)MTX (n=105)Effectiveness:no. of patients (%)a47(17.87%)26 (27.1%)7 (11.2/%)14 (13.3%)Cost of all RA-related medication per effectively treated patient(SD)$892.75(911.57)$833.46 (252.67)$2554.5 (1273.13)$171.4 (110.33)Average cost of all RA medications postindex (excluding biologic DMARDs) per patient (SD)b$146.38(114.60)$148.81 (123.12)$86.90 (74.53)$171.4 (110.33)Average cost of only biologicDMARDs postindex per patient (SD)b$746.38(926.35)$684.27(188.67)$2468.67(1285.91)/a χ2showed significant difference in percentage effectiveness for the original algorithm (p<0.05).bMedication cost was 2020 U.S. dollars.ConclusionIGU with MTX therapy was revealed to be both effective and modestly priced, which seemed to be a cost-effective strategy for RA therapy and warranted further cost-effectiveness investigation.References[1](2018) [2018 Chinese guideline for the diagnosis and treatment of rheumatoid arthritis].

BACKGROUND Pulmonary neuroendocrine tumors (pNETs) include typical carcinoid (TC), atypical carcinoid (AC), large cell neuroendocrine carcinoma (LCNEC), and small cell lung carcinoma (SCLC). The optimal treatment strategy for each subtype remains elusive, partly due to the lack of comprehensive understanding of their molecular features. We aimed to explore differential genomic signatures in pNET subtypes and identify potential prognostic and therapeutic biomarkers. METHODS We investigated genomic profiles of 57 LCNECs, 49 SCLCs, 18 TCs, and 24 ACs by sequencing tumor tissues with a 520-gene panel and explored the associations between genomic features and prognosis. RESULTS Both LCNEC and SCLC displayed higher mutation rates for TP53, PRKDC, SPTA1, NOTCH1, NOTCH2, and PTPRD than TC and AC. Small cell lung carcinoma harbored more frequent co-alterations in TP53-RB1, alterations in PIK3CA and SOX2, and mutations in HIF-1, VEGF and Notch pathways. Large cell neuroendocrine carcinoma (12.7 mutations/Mb) and SCLC (11.9 mutations/Mb) showed higher tumor mutational burdens than TC (2.4 mutations/Mb) and AC (7.1 mutations/Mb). 26.3% of LCNECs and 20.8% of ACs harbored alterations in classical non-small cell lung cancer driver genes. The presence of alterations in the homologous recombination pathway predicted longer progression-free survival in advanced LCNEC patients with systemic therapy (P = .005) and longer overall survival (OS) in SCLC patients with resection (P = .011). The presence of alterations in VEGF (P = .048) and estrogen (P = .018) signaling pathways both correlated with better OS in patients with resected SCLC. CONCLUSION We performed a comprehensive genomic investigation on 4 pNET subtypes in the Chinese population. Our data revealed distinctive genomic signatures in subtypes and provided new insights into the prognostic and therapeutic stratification of pNETs.

Abstract
Anterior and posterior approaches exist for the treatment of spinal pathologies. Anatomically, the 7th cervical spinal nerve(C7)crosses the C6-C7 intervertebral foramen bilaterally, allowing contralateral prevertebral or posterior C7 nerve transfer to be used. The advantage of the posterior rather than the anterior spinal approach is that it does not require retraction of important blood vessels, nerves, or other structures. In this paper, we describe transfer of the contralateral C7 nerve using a posterior approach.

Abstract
Background To investigate the comprehensive genomic profiling and programmed cell death ligand-1 (PD-L1) expression of primary lymphoepithelioma-like carcinoma (LELC) of different anatomical sites in the Chinese population and explore potential therapeutic strategies. Methods Capture-based targeted sequencing was performed on tumor tissue samples collected from 35 patients with LELC. Tumor tissues were stained by immunohistochemistry (IHC) for PD-L1. The molecular features of LELC of the stomach/parotid gland and associations between somatic alterations and survival outcomes in LELC of the stomach were explored. Results All patients with LELC of the stomach/parotid gland were microsatellite-stable with Epstein-Barr virus infection. A total of 215 somatic alterations spanning 126 genes were identified from 18 patients with LELC of the stomach. The most frequently mutated genes included PIK3CA, ARID1A, SMAD4, and KMT2D. In addition, 37 somatic alterations spanning 30 genes were identified from seven patients with LELC of the parotid gland. TP53, GNAS, and BCOR were the most frequently mutated genes. All cases of LELC of the stomach/parotid gland had a low tumor mutational burden (TMB) level, but a high PD-L1 expression level. Compared with LELC of the parotid gland, LELC of the stomach had a significantly higher TMB (1.0 vs. 5.0 mutations/Mb, P=0.0047) and a lower PD-L1 expression level (combined positive score: 90.0 vs. 47.5, P=0.0058). In addition, the presence of alterations in the p53 signaling pathway, homologous recombination pathway, and deoxyribonucleic acid (DNA) damage response pathway predicted unfavorable overall survival in patients with LELC of the stomach. Conclusions This study is the first to elucidate the comprehensive genomic profiling of LELC of the stomach in the Chinese population, and the first to demonstrate the molecular features of LELC of the parotid gland. The detection of high PD-L1 expression raises the potential of checkpoint immunotherapy for LELC of the stomach/parotid gland.

Abstract
It is a case found during routine reexamination one year after implantable Collamer lens (ICL) implantation. The patient had no complaints. The naked eye visual acuity of the left eye was 1.0, and abnormal blood vessels were seen in the supranasal retina. After fluorescein fundus angiography and sweep source OCTA, it was finally diagnosed as retinoschisis with microvascular anomalies of the left eye. This case suggests that the fundus of patients with high myopia without complaint should also be examined in detail and comprehensively. In addition to paying attention to peripheral retinopathy, the posterior pole and middle peripheral retina should be carefully examined, especially the areas that cannot be covered by conventional OCT.(Chin J Ophthalmol, 2021, 57: 944-945).

Abstract
Phase modulators based upon the thermo-optic effect are used widely in silicon photonics for low speed applications such as switching and tuning. The dissipation of the heat produced to drive the device to the surrounding silicon is a concern as it can dictate how compact and tightly packed components can be without concerns over thermal crosstalk. In this paper we study through modelling and experiment, on various silicon on insulator photonic platforms, how close waveguides can be placed together without significant thermal crosstalk from adjacent devices.

Abstract
Abstract
Background
Several electrocardiographic (ECG) indices have previously been proposed to diagnose left ventricular hypertrophy (LVH). Such indices utilize different criteria, including increased QRS voltage, prolonged QRS duration, left axis deviation, and LAFB and LBBB-like patterns in varying combinations. However, the inter-relationships of these different electrocardiographic indices of LVH with each otherare not fully understood.
The purpose of this study is to estimate the relationships between the different LVH indices.
Methods
Electronic tracings of 12-lead ECGs recorded in 24,786 adult participants in the China Kadoorie Biobank recorded in 2014 were accessed to detect presence of LVH. ECG parameters of LVH, including individual and combinations of such parameters (voltage-only criteria such as Sokolov-Lyon, Cornell, Gubner as well as scores such as Romhilt-Estes point score) were estimated using customized computer software (Cardiolyse Oy, Finland) and compared proprietary LVH point score algorithms (Mortara, USA). Relationships between the different indices were assessed using a correlation matrix to explore associations between individual parameters and combined indices of such parameters. The matrices were used to construct heat maps and identify clustering of individual parameters.
Results
Overall, approximately 10% of the population had LVH assessed by Mortara algorithms. This graph shows that along with the free standing peaks, the rest are divided into two clusters of interconnected individual parameters. In the center of the largest cluster is the parameter, reflecting R-peak magnitude in aVL lead. In the center of another cluster was the left ventricular strain pattern, as described in Romhilt-Estes point score system. Overall, the Sokolov-Lyon index and LVH point score in Veritas algorithm had the strongest relationships with each other, but the Gubner and Cornell indices had relatively weak correlations with the other indices (Table 1). The mean correlation coefficient between five combined LVH indices was as follows: Veritas (Mortara) – 0.58, Sokolov-Lyon – 0.56, Romhilt-Estes – 0.45, Gubner – 0,32, Cornell – 0,3.
Conclusions
Parameters such as R-peak magnitude in aVL and left ventricular strain pattern were the most strongly related with each other. Aggregate indices, such as the Sokolov-Lyon index and LVH point score in Veritas algorithm were the most strongly related with all other indices, but the Gubner and Cornell indices were only weakly correlated. The results reinforce the utility of Sokolov-Lyon index and Mortara algorithms as the optimum measures of LVH.

Abstract
Abstract
Background
Evidence on the association between dairy consumption and risk of cardiovascular disease has been highly inconsistent, with findings suggesting either harmful, neutral or beneficial effects. In addition, a very large majority of the previous studies on this topic were conducted among populations in Europe and North America who usually consume a higher amount of dairy products and very few data, particularly prospective data, come from China where the dairy consumption level is low.
Purpose
We therefore investigated the associations between intake of dairy products and incidence of several major types of cardiovascular diseases in Chinese adults.
Methods
During 2004–2008, the prospective China Kadoorie Biobank Study recruited slightly over 0.5 million adults from ten diverse regions (five urban and five rural) across China. Information on the consumption frequency of dairy products was collected at baseline and periodic resurveys, using a validated interviewer-administered laptop-based questionnaire. Over a mean follow-up of 10.9 years, there were 47,128 incident ischaemic heart disease events, 43,481 ischaemic strokes and 9749 intracerebral haemorrhages among 489,595 study participants, who did not report a prior history of cardiovascular disease at baseline. Cox regression analyses were performed to estimate multivariable-adjusted hazard ratios (HRs) for incident events associated with dairy intake.
Results
Overall, 69.3% of participants reported never or rare consumption (i.e. non-consumers) and 11.3% of them reported regular consumption (i.e. ≥4 days/week) of dairy products, with milk accounting for the largest proportion of total dairy intake (∼77%). Male and female regular dairy consumers had 2.1/1.5 and 1.7/1.1 mmHg lower systolic/diastolic blood pressure, respectively compared to non-consumers. In a subset (∼18,000) of participants with blood lipid levels measured, regular dairy consumers had ∼0.1 mmol/L higher LDL levels than non-consumers. After adjusting for a range of potential confounders, including sociodemographic and lifestyle factors, BMI and other dietary factors, dairy consumption was positively and significantly associated with risk of ischaemic heart disease, with the adjusted HR per 50 g/day increase in usual dairy consumption being 1.11 (95% confidence interval [CI] 1.09–1.14). Dairy consumption was not significantly associated with risk of ischemic stroke but was inversely associated with risk of intracerebral haemorrhage, with each 50 g/day increase in usual dairy consumption being associated with 17% lower risk (HR 0.83, 0.78–0.88). These associations remained significant after additional adjustment for systolic blood pressure.
Conclusion
In this large study of Chinese adults, higher intake of dairy products was associated with a higher risk of ischaemic heart disease but a lower risk of intracerebral haemorrhage. The exact mechanisms underlying such associations require further investigation.

Abstract
Abstract
Background
Higher red meat intake and lower fish intake have been associated with increased risk of cardiovascular disease (CVD), while the relevance of poultry and egg intake for CVD incidence remains inconclusive. Furthermore, most of the prospective evidence comes from studies in the Western populations, with limited data from China where the CVD patterns are largely different.
Purpose
We therefore investigated the associations of red meat, poultry, fish and egg intake with risks of several major types of CVD in Chinese adults.
Methods
The China Kadoorie Biobank is a prospective study which recruited ∼512,000 adult participants from ten diverse localities during 2004–08. At baseline and periodic resurveys, information on the consumption frequency of major food groups was collected using a validated interviewer-administered laptop-based questionnaire, together with medical history, socio-demographic and other lifestyle factors. During an average follow-up of 10.9 years, 47,128 incident ischaemic heart disease events, 43,481 ischaemic strokes and 9749 intracerebral haemorrhages were recorded among 489,595 participants, who did not have a prior history of CVD at baseline. Cox regression was used to calculate adjusted hazard ratios (HRs) relating dietary exposures to CVD risk.
Results
There were 47.2%, 1.4%, 9.0% and 24.1% of participants at baseline who regularly consumed (i.e. ≥4 days/week) red meat, poultry, fish and eggs, respectively. After adjusting for potential confounders, including body mass index and other dietary factors under study, egg consumption was significantly associated with lower risks of ischaemic heart disease and ischaemic stroke, with each 50 g/day increase in estimated habitual egg consumption being associated with 18% (HR 0.82, 95% confidence interval [CI] 0.75–0.90) and 24% lower risks (HR 0.76, 95% CI 0.69–0.84), respectively. Inverse associations were also observed between intakes of red meat, fish and eggs and risk of intracerebral haemorrhage, with adjusted HRs for 50 g/day higher intake being 0.84 (95% CI 0.74–0.97), 0.86 (95% CI 0.74–0.99) and 0.42 (95% CI 0.34–0.51), respectively.
Conclusion
This large prospective study of Chinese adults showed that higher intake of eggs was associated with lower risks of ischaemic heart disease and ischaemic stroke. Moreover, higher intakes of red meat, fish and eggs were each associated with a lower risk of intracerebral haemorrhage. Further investigation of the potential mechanisms that underlie the observed associations is required.

Abstract
Anaplastic lymphoma kinase (ALK) rearrangement occurs in approximately 5% of non-small cell lung cancers (NSCLCS), and EML4-ALK is the most commonly observed ALK fusion variant in NSCLC. However, growth hormone receptor (GHR) as the fusion partner for ALK and the clinical response to ALK tyrosine kinase inhibitors in patients with metastatic lung adenocarcinoma (LUAD) who carry the GHR-ALK variant have not been documented. This case describes a 63-year-old woman diagnosed with metastatic LUAD. Immunohistochemistry revealed positive ALK expression, and the patient was treated with crizotinib. After 3 weeks of treatment, the patient had a partial response. Because of treatment-related adverse events, the dose of crizotinib was reduced. After 3.7 months, computed tomography uncovered disease progression. Next-generation sequencing identified a novel GHR-ALK fusion in the plasma of the patient. The patient was treated again with crizotinib, but the disease progressed again 2 months later. Then, the patient received chemotherapy. She succumbed to her disease 11 months after the initial diagnosis. Our work provides evidence supporting the use of crizotinib in patients with metastatic LUAD harboring GHR-ALK.

Abstract
Cervical cancer patients who develop distant metastasis are rarely curable with very limited treatment options. Chemotherapy is often administered but with limited efficacy. Immunotherapy and anti-angiogenesis therapy are recommended for selected cases of recurrent or metastatic cervical cancers. The clinical efficacy of inhibitors targeting HER2, a commonly mutated gene in cervical cancer, has not been elucidated. Herein, we report a metastatic cervical adenocarcinoma patient carrying HER2 G292R who benefited from pyrotinib after progression on radio-chemotherapy, achieving complete response (CR) with a progression-free survival of 25 months and counting. Our study sheds light on the treatment options for previously treated metastatic cervical adenocarcinoma patients harboring activating HER2 mutations.

Abstract
We investigate the magnetic properties of a chemically heterogeneous binary-main-phase (BMP) Nd-Ce-Fe-B magnet with a core-shell structure via micromagnetic simulation. It is found that the coercivity strongly depends on the shell thickness. The BMP magnet's coercivity initially increases and then decreases with increasing Nd-rich shell thickness, and so there is the optimal shell thickness which shows the maximum coercivity for any given Ce concentration. The simulation shows the significant difference in coercivity and maximum energy product between the BMP and single-main-phase magnets. Notably, the magnetization reversal mechanism of the BMP magnet is revealed in the simulation. Local reversals in the BMP magnet first occur in the Ce-rich shells, followed by the Nd-rich cores. Then, the magnetization in Ce-rich core/Nd-rich shell typed grains is switched after reversed magnetization of all the Nd-rich core/Ce-rich shell typed grains. The BMP magnet represents a further increased coercivity for a larger GB thickness, which can be well explained by a maximum stray field.

Abstract
Evaluate the effect of the fresh air purification system on the improvement of indoor PM2.5 levels in a primary school classroom in Jinan City, Shandong Province. Our purpose is to explore the optimal operating time of the fresh air system and the main factors that affect the fresh air purification system to improve indoor air quality. From December 9, 2019 to December 10, 2019, two classrooms of the same area on the third floor of a primary school building in Jinan City, Shandong Province were selected as monitoring points. During the operation of the fresh air purification system, the PM2.5 concentration in the classroom is reduced by an average of 48.1%-61.5% compared to the outdoor PM2.5 concentration. After running for about 2 hours, the indoor PM2.5 concentration decreased to a relatively stable concentration level. The operating time of the fresh air purification system, student activities between classes, indoor temperature, indoor relative humidity, and outdoor PM2.5 concentration are important factors that affect the indoor particulate removal rate. In the case of a certain amount of fresh air and indoor area, closing doors and windows and appropriately extending the operation time of the fresh air purification system can improve the air quality in the classroom to a certain extent and protect the health of students.

Background/significance. Cardiac rehabilitation (CR) significantly reduces death, reoccurring cardiac events, hospital admissions while improving quality of life. However, it is still poorly attended with participation rates worldwide between 20-50%, worsened for rural and remote patients by the tyranny of distance, work responsibilities and transportation. Web-based CR can provide an alternative, patient centred, flexible delivery option. Co-design with consumers and clinicians is recommended to tailor web-based CR to their needs and preferences as a means of increasing attendance.
Purpose. The objective of this study is to describe how patient-generated data through workshops on desired content and features informs technology and implementation specifications for the patient portal of a CR website.
Methods. UX Design theoretical framework, using a co-design workshop, with thematic analysis, a survey, and the System Usability Scale was used to report outcomes.
Results. Based on the feedback from participants in rural and remote SA, desired content and features were updated for improving user experience. We recruited 27 participants across 4 regional Local health Networks in SA. The median age of participants was 71.0 (IQR 58-78), 14 (51.9%) were female and 27 (100%) had completed a cardiac rehabilitation program. More than half used a smart phone (16; 59.3%) and Facebook (21; 77.8%). Overall usability remains low based on a mean SUS score of 63.4 (SD 21.1), however there was a tendency to usability improving over time.
Conclusion. The co-design process has contributed to the development of the CR website, improving desired content and features. Improved usability scores can be achieved through further incorporating consumer feedback into the development of the CR website.

Abstract
PURPOSE The safety of mirabegron 50mg monotherapy was comprehensively assessed versus placebo for overactive bladder. METHODS A systematic literature search was conducted up to June, 2020 using PUBMED, EMBASE and Cochrane Library. Randomized controlled trials evaluating safety of mirabegron in overactive bladder were collected, and safety was assessed according to 15 adverse events. Adverse events were widely selected to be assessed if they could be calculated. Heterogeneity among studies was assessed by using the χ2 test based on the Q and I2 tests. Pooled effect sizes were calculated using fixed model if I2<50%, otherwise a random-effects model was chosen. The outcomes were nasopharyngitis, dry mouth, hypertension, constipation, headache, dyspepsia, urinary tract infection, dizziness, blurred vision, nausea, cardiovascular events, influenza, electrocardiogram QT prolonged, upper respiratory tract infection and high blood pressure. RESULTS In all, 10 peer-reviewed trials comprising 6135 patients were identified. Compared with placebo, mirabegron 50mg had an unfavorable safety profile resulting in nasopharyngitis (OR, 1.54[95% credible interval, 1.05-2.25]; P=0.03. No statistical difference was found between mirabegron 50mg and placebo groups in other 14 outcomes. CONCLUSION Mirabegron 50mg is further confirmed to be nearly as safe as placebo, expect for nasopharyngitis. Nasopharyngitis is associated with mirabegron 50mg monotherapy for patients with overactive bladder.

Abstract
Objective: To understand the epidemiological and genotypic characteristics of imported cases of measles virus of D8 genotype in Hebei province. Methods: Epidemiological investigation of measles cases in surveillance was carried out. The throat swabs of the measles cases in acute phase were collected for real time RT-PCR identification, measles virus culture and genotype identification. Results: A total of 36 imported measles cases of genotype D8 were detected. The cases were mainly distributed in 8 counties of Handan city. Number of confirmed measles cases in Cheng'an county was the highest, accounting for 58.33% (21/36) of all the reported cases. All patients had fever and rash, and 55.55% (20/36) of the cases were under 2 years old and 86.11% (31/36) of the cases had no immunization history. The children with pneumonia accounted for 44.12% (15/34) of the total children with D8 genotype measles virus infection. The nucleotide and amino acid homologies between the imported measles virus genotype D8 and the WHO reference strain of D8 genotype (D8-Manchester.UNK/30.94) were 98.4%-98.6% and 97.3%, respectively. Compared with the strains of H1 genotype in China, the nucleotide and amino acid homologies were 92.8%-93.1% and 93.3%, respectively. Conclusions: The imported cases of measles virus of D8 genotype might have caused local transmission in Hebei province. Molecular epidemiological surveillance for measles virus needs to be further strengthened. It is necessary to detect and control the epidemic early and improve the coverage rate and timely rate of measles vaccination. It is also important to prevent cross infection in hospitals.

Abstract
e15079 Background: Signet-ring cell carcinoma (SRCC) of rectum and sigmoid colon is an extremely rare subtype of colorectal cancer (CRC) with very poor prognosis. Tumor-infiltrating lymphocytes (TILs) signify the host immune response to tumors, which were reported to predict survival outcomes of patients with various cancer types. In this study, we aimed to characterize TILs and mutational features of SRCC of rectum and sigmoid colon as well as their correlations with the clinicopathological parameters and survival outcomes. Methods: 28 patients with stage II-IV SRCC of rectum and sigmoid colon were included, in which 12 patients had tumors with ≥50% signet-ring cells (SRCs) and 16 had tumors with <50% SRCs. Targeted next generation sequencing using a 1,021-gene panel was used to investigate the genetic alterations of tumor tissue. Multiplex immunofluorescence assays were performed to visualize TILs. TILs within cancer cell nests (iTILs) and in cancer stroma (sTILs) were counted separately. The correlations of TILs with survival outcomes were analyzed in stage II/III patients who underwent the radical resection. Results: Somatic alterations were detected in all the 28 cases. The most frequently mutated genes included TP53, APC and SMAD4, occurring in 68%, 36% and 36% of cases, respectively. BRAF mutation were detected in only one patient (3.6%). The median tumor mutational burden (TMB) was 4.80 (range, 0.96-42.24) muts/Mb. Three patients (10.7%) were with microsatellite instability-high (MSI-H) status and a high TMB of more than 10 muts/Mb. Patients with stage IV tumors have significantly lower PD-1+ CD8+ iTILs and sTILs (p=0.018 for both), CD8+ iTILs (p=0.022), and PD-1+ iTILs (p=0.013) levels than those with stage II/III tumors. Tumors with ≥ 50% SRCs showed lower levels of CD8+ sTILs than those with < 50% SRCs (p=0.046). Patients with CEA>5.0 ng/ml showed significantly lower levels of PD-1+ CD8+ iTILs than those with CEA≤5.0 ng/ml (p=0.015). Moreover, significantly lower levels of PD-1+ CD8+ sTILs (p=0.036) were observed in tumors that appeared as long circumferential thickening of the bowel wall with stenosis compared to those did not. Multivariate analysis indicated that patients with high PD-1+ CD8+ iTILs and sTILs levels had significantly better disease-free survival (DFS) than those with low PD-1+ CD8+ iTILs and sTILs levels (not reached vs. 22 months for both; p=0.008 and 0.003, respectively). High PD-1+ CD3+ sTILs levels were associated with significantly longer overall survival (OS) compared to low levels (not reached vs. 39 months, p=0.034). No correlation between MSI or TMB and DFS or OS was observed in this small cohort. Conclusions: Our results demonstrated that PD-1+ CD8+ iTILs and sTILs are powerful independent predictors of survival outcomes in patients with resectable SRCC of rectum and sigmoid colon. Further investigations in larger cohorts are needed to validate our findings.

Abstract
e16279 Background: Lymphoepithelioma-like carcinoma (LELC) of the stomach is a rare histological type of gastric cancer (GC) with an incidence of 1-4% all GCs, characterized by Epstein-Barr virus infection (EBV+). There is no established agent for patients with LELC of the stomach due to the lack of the genomic data. In this work, we performed the comprehensive genomic profiling and PD-L1 expression of primary LELC of the stomach to investigate the molecular mechanism of tumorigenesis. Methods: Capture-based targeted sequencing was performed on tumor tissue samples collected from 20 patients with LELC of the stomach and 8 patients with LELC of the parotid gland using a panel consisting of 520 cancer-related genes. Tumor tissues were stained by immunohistochemistry for PD-L1 and CD8. PD-L1 expression level was determined by combined positive score (CPS). Tumor mutation burden (TMB) was calculated as a ratio of the total nonsynonymous mutations per total coding region of the panel, excluding copy number variations and fusions. Results: Total of 217 somatic mutations in 127 genes were identified from 18 patients with LELC of the stomach. The most frequently mutated genes included PIK3CA, ARID1A, SMAD4 and KMT2D, occurring in 65% (13/20), 55% (11/20), 30% (6/20), and 25% (5/20) of patients with LELC of the stomach. For LELC of the parotid gland, 13 somatic mutations in 8 genes were identified from 7 patients. All patients with LELC of the stomach/parotid gland were EBV positive and microsatellite-stable. Patients with LELC of the stomach had a significantly higher mutation frequency in PIK3CA (65% vs. 0%, p < 0.01) and ARID1A (55% vs. 0%, p < 0.01) than patients with LELC of the parotid gland. Patients with LELC of the stomach also had a significantly higher mutation frequency in mTOR (70 vs. 0%, p < 0.001) and VEGF signaling pathway (70% vs. 0%, p < 0.001) than patients with LELC of the parotid gland. Compared to LELC of the parotid gland, LELC of the stomach showed a significantly increased TMB (5.0 vs. 1.0 muts/Mb, p < 0.001) and a decreased CPS (47.5 vs. 100.0, p < 0.01). Tumor-infiltrating CD8+ T cell densities in LELC of the stomach and LELC of the parotid gland were comparable. Next, we compared mutational profiling of LELC of the stomach from our cohort to mutational landscape of EBV+ gastric adenocarcinoma obtained from The Cancer Genome Atlas. Patients with LELC of the stomach had a significantly higher mutation frequency in PIK3CA than patients with EBV+ gastric adenocarcinoma (65% vs. 0%, p < 0.001). The mutation frequencies of ARID1A, SMAD4 and KMT2D between patients with LELC of the stomach and EBV+ gastric adenocarcinoma were comparable. Conclusions: This study is the first to elucidate the comprehensive genomic profiling of LELC of the stomach in the Chinese population. Our work demonstrated that genomic landscape of LELC of the stomach is distinctive to LELC of the parotid gland and EBV+ gastric adenocarcinoma.
