Abstract
Thromboangiitis obliterans (TAO) is a non-atherosclerotic segmental inflammatory occlusive disease with a high recurrence rate, high disability rate, difficulty to cure, and poor prognosis. It has been clinically proven that Mailuoshutong pill (MLSTP) is an effective traditional Chinese medicine for treating TAO. As MLSTP contains hundreds of chemical components, the quality control of which is a challenge in the development of reliable quality evaluation metrics. This study aimed to evaluate the quality uniformity of MLSTP by establishing a multi-strategy platform. In the present study, the key targets and signaling pathways of MLSTP treating TAO were predicted by network pharmacology. It was further shown by in vivo validation experiments that MLSTP exerted therapeutic effects on TAO by modulating the PI3K-AKT signaling pathway, VEGF signaling pathway, and HIF-1 signaling pathway. In addition, UPLC fingerprints of MLSTP were established and screened for potential Q-markers of MLSTP in combination with network pharmacology results. Six components, including chlorogenic acid, liquiritin, paeoniflorin, calycosin-7-glucoside, berberine, and formononetin, were selected as potential quality markers (Q-markers) in MLSTP. Finally, the quantitative analysis of multi-components by single marker (QAMS) method was established to quantitatively analyze the six potential Q-markers, and the results were consistent with those obtained by the external standard method (ESM). Taken together, the multi-strategy platform established in this study would be conducive to the Q-markers screening and quality control of MLSTP, improving the quality standard of MLSTP and providing favorable assurance for the clinical management of TAO.

Abstract
Background Inhibition of amyloid β protein fragment (Aβ) aggregation is considered to be one of the most effective strategies for the treatment of Alzheimer's disease. (-)-Epigallocatechin-3-gallate (EGCG) has been found to be effective in this regard; however, owing to its low bioavailability, nanodelivery is recommended for practical applications. Compared to chemical reduction methods, biosynthesis avoids possible biotoxicity and cumbersome preparation processes. Materials and Methods The interaction between EGCG and Aβ42 was simulated by molecular docking, and green tea-conjugated gold nanoparticles (GT-Au NPs) and EGCG-Au NPs were synthesized using EGCG-enriched green tea and EGCG solutions, respectively. Surface active molecules of the particles were identified and analyzed using various liquid chromatography-tandem triple quadrupole mass spectrometry methods. ThT fluorescence assay, circular dichroism, and TEM were used to investigate the effect of synthesized particles on the inhibition of Aβ42 aggregation. Results EGCG as well as apigenin, quercetin, baicalin, and glutathione were identified as capping ligands stabilized on the surface of GT-Au NPs. They more or less inhibited Aβ42 aggregation or promoted fibril disaggregation, with EGCG being the most effective, which bound to Aβ42 through hydrogen bonding, hydrophobic interactions, etc. resulting in 39.86% and 88.50% inhibition of aggregation and disaggregation effects, respectively. EGCG-Au NPs were not as effective as free EGCG, whereas multiple thiols and polyphenols in green tea accelerated and optimized heavy metal detoxification. The synthesized GT-Au NPs conferred the efficacy of diverse ligands to the particles, with inhibition of aggregation and disaggregation effects of 54.69% and 88.75%, respectively, while increasing the yield, enhancing water solubility, and decreasing cost. Conclusion Biosynthesis of nanoparticles using green tea is a promising simple and economical drug-carrying approach to confer multiple pharmacophore molecules to Au NPs. This could be used to design new drug candidates to treat Alzheimer's disease.

Abstract
Amphiphilic materials can be used for sample preparation of chromatography or mass spectrometry. Amphiphilic materials with magnetic properties in combination with magnetic suction devices allow for automated sample preparation. However, conventional synthesis methods are cumbersome and not suitable for the mass production of the material. In this study, a micro-suspension polymerization method was developed to synthesize magnetic amphiphilic resin microspheres (MARMs), providing new ideas for the preparation of amphiphilic microspheres. MARMs with particle sizes ranging from 3 to 6 μm were successfully prepared, with BET surface area up to 653.2 m2/g. A magnetic solid-phase extraction method based on MARM-5 was developed for the extraction of four glucocorticoids including Cortisone, Hydrocortisone, Cortodoxone, and Corticosterone. This method had a very short adsorption time of 0.5 min and a total extraction time of only 13 min. The limit of detection for the four glucocorticoids ranged from 0.22 to 0.82 ng/L. There was a good linear relationship between sample concentration and peak area in the range of 25∼500 ng/L. Relative recovery of 98 %∼108 % and internal standard normalized matrix effect factors of 95∼114 % were obtained, and the relative standard deviation was between 2.3 % and 6.3 %. The MARMs would be used as excellent solid extraction material for glucocorticoids.

Abstract
MicroRNAs (miRNAs) are of significance in tuning and buffering gene expression. Despite abundant analysis tools that have been developed in the last two decades, plant miRNA identification from next-generation sequencing (NGS) data remains challenging. Here, we show that we can train a convolutional neural network to accurately identify plant miRNAs from NGS data. Based on our methods, we also present a user-friendly pure Java-based software package called Small RNA-related Intelligent and Convenient Analysis Tools (SRICATs). SRICATs encompasses all the necessary steps for plant miRNA analysis. Our results indicate that SRICATs outperforms currently popular software tools on the test data from five plant species. For non-commercial users, SRICATs is freely available at https://sourceforge.net/projects/sricats.

Abstract
Cyanobacteria are attractive hosts for photosynthetic terpenoid production, using CO2 as the sole carbon source. Although the methylerythritol phosphate (MEP) pathway is superior to the mevalonate pathway for cyanobacterial terpenoid synthesis, the first reaction of the MEP pathway, which is catalyzed by 1-deoxy-d-xylulose-5-phosphate (DXP) synthase, involves complex regulation and carbon loss. Here, we constructed a direct route linking ribulose-5-phosphate (Ru5P) in the Calvin-Benson (CB) cycle with DXP in the MEP pathway in a cyanobacterium to increase the terpenoid yield from CO2 and bypass the DXS-targeted regulations. By employing the adaptive laboratory evolution, we identified new RibB variants including RibB 90-92del with a high activity of synthesizing DXP from Ru5P. These RibB variants were introduced into Synechococcus elongatus, resulting in the significantly increased photosynthetic production of isopentenol. The 13C tracer experiments demonstrated a direct carbon flow from Ru5P in the CB cycle to the MEP pathway; thus, this direct route was denoted as the Ru5P shunt. The strain harboring the Ru5P shunt produced 105.2 mg L-1 of isopentenol with an average rate of 17.5 mg L-1 d-1 under continuous light conditions, which is higher than those ever reported for five-carbon alcohol production by photoautotrophic microorganisms. Utilization of the Ru5P shunt in cyanobacterial cells also improved the pinene production, which demonstrates that this shunt can be used to enhance the photosynthetic production of diverse terpenoids.

Abstract
Pu-zhi-hui-ling decoction (PZHLD) is a traditional Chinese medicine (TCM) formula for the treatment of Alzheimer's disease (AD), but its chemical composition has not been reported. In this study, we aimed to establish a mass spectrometry (MS) analysis method for rapid classification and identification of the chemical constituents in PZHLD. The sample was analysed by ultrahigh-performance liquid chromatography coupled to quadrupole Orbitrap high-resolution mass spectrometry (UHPLC-Q-Orbitrap HRMS). The chemical constituents of PZHLD were identified based on accurate MS data, fragmentation characteristics of MS/MS, and reference information described in the literature. A total of 123 chemical constituents were identified. In addition, we summarised the fragmentation pathways of the chemical constituents in PZHLD. Our finding might lay the foundation for the further pharmacodynamic study and clinical application of PZHLD.

Abstract
Objective: To investigate the clinical and prognostic characteristics of newly diagnosed multiple myeloma (NDMM) patients with myelofibrosis (MF). Methods: The clinical data of 160 NDMM patients admitted to Henan Provincial People's Hospital from January 2012 to July 2022 were analyzed retrospectively. They were divided into MF group(n=74) and non-MF group(n=86) according to whether combined with MF. Patients in MF group were further splited into MF-1 group (n=47) and MF-2/3 group (n=27). All patients were treated with bortezomib and immunomodulatory-based combination therapy. The efficacy was evaluated after 4 courses, and the clinical features and prognosis between the two groups were compared. The deadline for follow-up was December 30, 2022 and the median follow-up period [M (Q1, Q3)] was 23.5 (14.4, 40.5) months. Kaplan-Meier method was used for survival analysis, and Cox regression model was used to analyze the influencing factors of survival. Results: Among 160 patients with NDMM, 91 were males and 69 were females, with a median age [M (Q1, Q3)] of 59 (54, 69) years. In MF group, the bone marrow immature plasma cell percentage, total plasma cell percentage were 9.6% (3.2%, 28.5%) and 36.4% (18.5%, 51.1%), respectively, which were higher than 6.0% (1.2%, 17.2%) and 24.0% (12.0%, 46.0%) of the non-MF group (both P<0.05). Hb level was 84.0(74.5, 100.5)g/L and PLT was (151.99±90.68) ×109/L in the MF group, which were lower than 96.0 (81.0, 112.0)g/L and (180.38±85.32) ×109/L of non-MF group (both P<0.05). But there were no significant differences in ISS stage, karyotypic and fluorescence in situ hybridization (FISH) high-risk genetic abnormalities between the two groups (all P>0.05). Objective response rate (ORR), overall survival (OS) and progression-free survival (PFS) were not significantly different between the two groups (all P>0.05). The rate of 17p- was 25.9% (7/27) in MF-2/3 group, which was higher than 8.1% (7/86) of non-MF group (P=0.049). The median OS of the MF-2/3 group was 25.0 (95%CI: 23.6-26.4) months, which was shorter than that of the non-MF group (54.0 months, P=0.031). Multivariate Cox regression analysis showed that grade MF-2/3 was not a risk factor for OS in NDMM patients (HR=1.507, 95%CI: 0.624-3.993, P=0.425). Conclusions: The ratio of bone marrow immature plasma cells and total plasma cells in NDMM patients with MF are higher than that in patients without MF, and the Hb and PLT are lower than that in patients without MF. NDMM patients with grade 2/3 MF have shorter survival than those without MF.

Abstract
BACKGROUND Diabetic nephropathy (DN) is a major complication of diabetes. Schisandrin B (Sch) is a natural pharmaceutical monomer that was shown to prevent kidney damage caused by diabetes and restore its function. However, there is still a lack of comprehensive and systematic understanding of the mechanism of Sch treatment in DN. OBJECTIVE We aim to provide a systematic overview of the mechanisms of Sch in multiple pathways to treat DN in rats. METHODS Streptozocin was used to build a DN rat model, which was further treated with Sch. The possible mechanism of Sch protective effects against DN was predicted using network pharmacology and was verified by quantitative proteomics analysis. RESULTS High dose Sch treatment significantly downregulated fasting blood glucose, creatinine, blood urea nitrogen, and urinary protein levels and reduced collagen deposition in the glomeruli and tubule-interstitium of DN rats. The activities of superoxide dismutase (SOD) and plasma glutathione peroxidase (GSH-Px) in the kidney of DN rats significantly increased with Sch treatment. In addition, the levels of IL-6, IL-1β, and TNF-α were significantly reduced in DN rats treated with Sch. 11 proteins that target both Sch and DN were enriched in pathways such as MAPK signaling, PI3K-Akt signaling, renal cell carcinoma, gap junction, endocrine resistance, and TNF signaling. Furthermore, quantitative proteomics showed that Xaf1 was downregulated in the model vs. control group and upregulated in the Sch-treated vs. model group. Five proteins, Crb3, Tspan4, Wdr45, Zfp512, and Tmigd1, were found to be upregulated in the model vs. control group and downregulated in the Sch vs. model group. Three intersected proteins between the network pharmacology prediction and proteomics results, Crb3, Xaf1, and Tspan4, were identified. CONCLUSION Sch functions by relieving oxidative stress and the inflammatory response by regulating Crb3, Xaf1, and Tspan4 protein expression levels to treat DN disease.

Abstract
Biomanufacturing of ethylene is particularly important for modern society. Cyanobacterial cells are able to photosynthesize various valuable chemicals. A promising platform for next-generation biomanufacturing, the semiconductor-cyanobacterial hybrid systems are capable of enhancing the solar-to-chemical conversion efficiency. Herein, the native ethylene-producing capability of a filamentous cyanobacterium Nostoc sphaeroides is confirmed experimentally. The self-assembly characteristic of N. sphaeroides is exploited to facilitate its interaction with InP nanomaterial, and the resulting biohybrid system gave rise to further elevated photosynthetic ethylene production. Based on chlorophyll fluorescence measurement and metabolic analysis, the InP nanomaterial-augmented photosystem I activity and enhanced ethylene production metabolism of biohybrid cells are confirmed, the mechanism underlying the material-cell energy transduction as well as nanomaterial-modulated photosynthetic light and dark reactions are established. This work not only demonstrates the potential application of semiconductor-N. sphaeroides biohybrid system as a good platform for sustainable ethylene production but also provides an important reference for future studies to construct and optimize nano-cell biohybrid systems for efficient solar-driven valuable chemical production.

Abstract
Over the past few decades, micro liquid dispensing technology has been widely used in biology, chemistry, material and environmental sciences due to its efficacy in processing multiple samples. For practical applications, precise and effective droplet generation is very important. Despite numerous droplet generation methods, the implementation of droplet-on-demand still faces challenges concerning system complexity, precision, cost, and robustness. In this work, a novel on-demand contacting droplet generation method incorporated with model-based feedback control with an image processing unit as a sensor was proposed. By studying droplet identification using image processing techniques, the model of droplet formation was simplified. Then model-based feedback control was implemented using volumes of dispensed samples as sensing signals by tuning related parameters adaptively to resist disturbances. The proposed method was integrated and applied to a homebuilt automated micro liquid dispensing system with droplets ranging from 20 nanoliter to 200 nanoliter. The experimental results demonstrated a high degree of accuracy and precision. Additionally, the proposed system's practical utility was evaluated by analyzing mutations in genes associated with sensorineural hearing loss, verifying its effectiveness.

Abstract
PURPOSE/OBJECTIVE(S) Prior studies suggested excessive toxicity for central lung tumors treated with 3-fraction stereotactic body radiation therapy (SBRT). This may be related to the high biologically equivalent dose assuming alpha/beta of 10 (BED) of 54 Gy in 3 fractions (BED = 151.2), as 50-60 Gy in 5 fractions (BED = 100.0-132.0) was well-tolerated in RTOG 0813. We initiated a prospective phase IB/II trial to test the hypothesis that a dose-deescalated regimen of 45 Gy in 3 fractions (BED 112.5) would be safe and efficacious in central lung tumors. MATERIALS/METHODS We enrolled patients with primary or secondary lung tumors ≤5cm in a central but not ultra-central tumor location defined as within 2 cm of (but not abutting) tracheobronchial tree, esophagus, or heart. Patients were either medically inoperable or refused surgical intervention. Co-primary endpoints were safety and efficacy, defined as local control (LC). Secondary endpoints included lobar control, regional control (LRC), distant control (DC), progression-free survival (PFS), cancer-specific survival (CSS), and overall survival (OS). Organ-at-risk dose constraints were consistent with those of RTOG 0236. The Bayesian predictive probability approach was utilized for continuous monitoring after 10 patients were treated and have mature assessment of toxicity, after which interim analysis was planned. We recommended terminating the trial for safety if there was sufficient evidence that the rate of grade ≥3 was greater than 0.25 (predictive probability >0.80). RESULTS As of the data cut-off date of 1/26/23, the trial was open for 34 months (including a nearly-immediate suspension due to the COVID-19 pandemic). A total of 17 patients have been treated on protocol with a median follow-up of 12 months. No grade ≥3 adverse events attributable to SBRT have occurred to date, though one patient died of unrelated cardiac arrhythmias 1 month after SBRT completion (Table 1). Maximum CTCAE grade 2 adverse events attributable to SBRT occurred in 17.6% of patients. The predictive probability of concluding unacceptably high toxicity rate by the end of the trial based on toxicity data in the current stage is 0.62%. To date, there have been 0 local recurrences, 1 regional recurrence without local recurrence (8 months after SBRT completion, successfully salvaged with definitive chemoradiotherapy without additional toxicities), and 1 distant recurrence without local recurrence (6 months after SBRT in a patient with lung metastasis from colon adenocarcinoma). CONCLUSION Interim analysis of the DD3 trial suggests that for patients with central but not ultra-central lung tumors, an SBRT regimen of 45 Gy in 3 fractions warrants continued trial accrual and follow-up given no grade ≥3 toxicities or local recurrences in the early follow-up period among the first 17 patients enrolled.

Abstract
Background Vertigo and hearing loss are both prevalent in the elderly. This study retrospectively analyzed hearing test results from elderly patients experiencing vertigo and dizziness at ENT outpatient over a 10-year period, in order to study the patterns of hearing loss in this patient population. Methods Nine thousand three hundred eighty four patients over 50 years old underwent retrospective collection and screening of outpatient diagnosis, pure tone audiometry, acoustic immittance measurement (tympanogram) and auditory brainstem response (ABR) test. The patient's audiograms are divided into 7 subtypes according to a set of fixed criteria. Meanwhile, K-Means clustering analysis method was used to classify the audiogram. Results The Jerger classification of tympanogram in elderly patients with vertigo and dizziness showed the majority falling under type A. The leading audiogram shapes were flat (27.81% in right ear and 26.89% in left ear), high-frequency gently sloping (25.97% in right ear and 27.34% in left ear), and high-frequency steeply sloping (21.60% in right ear and 22.53% in left ear). Meniere's disease (MD; 30.87%), benign recurrent vertigo (BRV; 19.07%), and benign paroxysmal positional vertigo (BPPV; 15.66%) were the most common etiologies in elderly vestibular diseases. We observed statistically significant differences in hearing thresholds among these vestibular diseases (P < 0.001). K-Means clustering analysis suggested that the optimal number of clusters was three, with sample sizes for the three clusters being 2,747, 2,413, and 4,139, respectively. The ANOVA statistical results of each characteristic value showed P < 0.001. Conclusion The elderly patients often have mild to moderate hearing loss as a concomitant symptom with vertigo. Female patients have better hearing thresholds than males. The dominant audiometric shapes in this patient population were flat, high-frequency gently sloping, and high-frequency steeply sloping according to a set of fixed criteria. This study highlights the need for tailored strategies in managing hearing loss in elderly patients with vertigo and dizziness.

Abstract
Quadrupole mass spectrometers (QMS) are widely used for clinical diagnosis and chemical analysis. To obtain the best experimental results, mass spectrometers must be calibrated to an ideal setting before use. However, tuning the current QMS is challenging. Traditional tuning techniques possess low automation levels and rely primarily on skilled engineers. Therefore, in this study, we propose an innovative auto-tuning algorithm for QMS based on the improved particle swarm optimization (PSO) algorithm to automatically find the optimal solution of QMS parameters and make the QMS reach the optimal state. The improved PSO algorithm is combined with simulated annealing, multiple inertia weights, dynamic boundaries, and other methods to prevent the traditional PSO algorithm from the issue of a local optimal solution and premature convergence. According to the characteristics of the mass spectrum peaks, a termination function is proposed to simplify the termination conditions of the PSO algorithm and further improve the automation level of the mass spectrometer. The results of auto-calibration testing of resolution and mass axis show that both resolution and mass axis calibration could effectively meet the requirements of mass spectrometry experiments. By the experiment of auto-optimization testing of lens and ion source parameters, these parameters were all in the vicinity of the optimal solution, which achieved the expected performance. Through numerous experiments, the reproducibility of the algorithm was established as meeting the auto-tuning function of the QMS. The proposed method can automatically tune the mass spectrometer from its non-optimal condition to the optimal one, which can effectively reduce the tuning difficulty of QMS.

Abstract
Alzheimer's disease (AD) is a common neurodegenerative disease. The drugs widely used in clinic are mainly single-target drugs for symptomatic treatment, which can only alleviate symptoms to a certain extent. Ecliptae Herba (EH) is considered a potential therapeutic drug for AD due to its neuroprotective effects. Although EH has a clear anti-AD effect, the material basis and mechanism remain unclear. Therefore, we adopted an efficient analytical technique, namely ultra-high-performance liquid chromatography quadrupole time-of-flight mass spectrometry (UPLC-Q-TOF/MS), combined with "component-target-pathway" network to explore the active components and potential mechanisms of EH in treating AD. Due to the high sensitivity of UPLC-Q-TOF/MS, a total of 50 components were identified in EH. Among them, 20 and 12 compounds were found in plasma and brain samples, respectively. The network pharmacology analysis revealed that apigenin, luteolin, ecliptasaponin A, chlorogenic acid, wedelolactone, and quercetin were the active components, which could affect the serotonergic synapse, calcium and cAMP signaling pathways by regulating related targets such as EGFR, PRKCA, BRAF and ERBB2. This study clarified that EH can exert anti-AD effect through multi-component, multi-target and multi-pathway characteristics. Furthermore, it offers a good foundation for further in-depth research on the anti-AD effects of EH, and provides a valuable approach for the rapid screening of active components and potential mechanisms of other medicinal plants, potentially bringing changes to the discovery and development of novel therapeutics for neurodegenerative disorders.

Abstract
Alpinia oxyphylla Fructus, called Yizhi in Chinese, is the dried fruit of Alpinia oxyphylla Miquel. It has been used in traditional Chinese medicine to treat dementia and memory defects of Alzheimer's disease for many years. However, the underlying mechanism is still unclear. In this study, we used a rat Alzheimer's disease model on intrahippocampal injection of aggregated Aβ1-42 to study the effects of Alpinia oxyphylla Fructus. A brain and plasma dual-channel metabolomics approach combined with multivariate statistical analysis was further performed to determine the effects of Alpinia oxyphylla Fructus on Alzheimer's disease animals. As a result, in the Morris water maze test, Alpinia oxyphylla Fructus had a clear ability to ameliorate the impaired learning and memory of Alzheimer's disease rats. 11 differential biomarkers were detected in AD rats' brains. The compounds mainly included amino acids and phospholipids; after Alpinia oxyphylla Fructus administration, 9 regulated biomarkers were detected compared with the AD model group. In the plasma of AD rats, 29 differential biomarkers, primarily amino acids, phospholipids and fatty acids, were identified; After administration, 23 regulated biomarkers were detected. The metabolic pathways of regulated metabolites suggest that Alpinia oxyphylla Fructus ameliorates memory and learning deficits in AD rats principally by regulating amino acid metabolism, lipids metabolism, and energy metabolism. In conclusion, our results confirm and enhance our current understanding of the therapeutic effects of Alpinia oxyphylla Fructus on Alzheimer's disease. Meanwhile, our work provides new insight into the potential intervention mechanism of Alpinia oxyphylla Fructus for Alzheimer's disease treatment.

Abstract
Early diagnosis of pathological markers can significantly shorten the rate of viral transmission, reduce the probability of infection, and improve the cure rate of diseases. Therefore, analytical techniques for identifying pathological markers and environmental toxicants have received considerable attention from researchers worldwide. However, the most popular techniques used in clinical settings involve expensive precision instruments and complex detection processes. Thus, a simpler, more efficient, rapid, and intelligent means of analysis must be urgently developed. Electrochemical biosensors have the advantages of simple processing, low cost, low sample preparation requirements, rapid analysis, easy miniaturization, and integration. Thus, they have become popular in extensive research. Machine learning is widely used in material-assisted synthesis, sensor design, and other fields owing to its powerful data analysis and simulation learning capabilities. In this study, a machine learning-assisted carbon black-graphene oxide conjugate polymer (CB-GO/CP) electrode, in conjunction with a flexible wearable device, is proposed for the smart portable detection of tyrosine (Tyr). Input feature value data are obtained for the artificial neural network (ANN) and support vector machines (SVM) model learning via multiple data collections in artificial urine and by recording the pH and temperature values. The results reveal that a machine-learning model that integrates multiple external factors is more accurate for the prediction of Tyr concentration.

Abstract
In the background of the rapid development of artificial intelligence, big data, IoT, 5G/6G, and other technologies, electrochemical sensors pose higher requirements for high-throughput detection. In this study, we developed a workstation with up to 10 channels, which supports both parallel signal stimulation and online electrochemical analysis functions. The platform was wired to a highly integrated Bluetooth chip used for wireless data transmission and can be visualized on a smartphone. We used this electrochemical test platform with carbon-graphene oxide/screen-printed carbon electrodes (CB-GO/SPCE) for the online analysis of L-tyrosine (Tyr), and the electrochemical performance and stability of the electrodes were examined by differential pulse voltammetry (DPV). The CB-GO-based screen-printed array electrodes with a multichannel electrochemical platform for Tyr detection showed a low detection limit (20 μM), good interference immunity, and 10-day stability in the range of 20-200 μM. This convenient electrochemical analytical device enables high-throughput detection and has good economic benefits that can contribute to the improvement of the accuracy of electrochemical analysis and the popularization of electrochemical detection methods in a wide range of fields.

Abstract
Pressure-stabilized high-entropy sulfide (FeCoNiCuRu)S2 (HES) is proposed as an anode material for fast and long-term stable lithium/sodium storage performance (over 85% retention after 15 000 cycles @10 A g-1 ). Its superior electrochemical performance is strongly related to the increased electrical conductivity and slow diffusion characteristics of entropy-stabilized HES. The reversible conversion reaction mechanism, investigated by ex-situ XRD, XPS, TEM, and NMR, further confirms the stability of the host matrix of HES after the completion of the whole conversion process. A practical demonstration of assembled lithium/sodium capacitors also confirms the high energy/power density and long-term stability (retention of 92% over 15 000 cycles @5 A g-1 ) of this material. The findings point to a feasible high-pressure route to realize new high-entropy materials for optimized energy storage performance.

Abstract
BACKGROUND Public housing estate is a key determinant of community health risk in American/European cities. However, how forms/characteristics of compact/hilly public housing's neighbourhoods affect dementia among Asian seniors was underestimated. DESIGN This was a cross-sectional study. METHODS A total of 2,077 seniors living in Hong Kong's public housing estates were included. Dementia was measured by a Cantonese version of Montreal - Cognitive Assessment. Built environment was measured based on three dimensions (greenery, walkability, accessibility), including 11 metrics. Circular buffers (without walking paths) and service areas (considering walking paths) with two-dimensional/three-dimensional (terrain) adjustment were applied to quantify forms/characteristics of neighbourhoods. Two spatial buffers were applied: immediate distance (200 m) and walkable distance (500 m). Exposure-by-exposure regressions were applied to evaluate the associations between form/characteristics of neighbourhood and dementia. RESULTS Forms/characteristics without considering walking paths may overestimate health benefits from built environment. For circular buffers, higher percentage of building coverage, higher land use mix and more community/transportation/leisure facilities were negatively associated with dementia. All measures of greenery were positively associated with dementia. For service areas, measures of walkability and accessibility became insignificant except more community facilities at the immediate distance. Furthermore, terrain effect was insignificant when it was compared with the impacts of walking paths. CONCLUSION Dementia among seniors in hilly public housing estates was negatively associated with neighbourhood's walkability and accessibility and was influenced by walking paths. For healthy ageing, improved forms/characteristics of public housing neighbourhoods should include more accessible spaces and community facilities along walking paths for physical activities and basic daily needs.

Abstract
Purpose: Pupil center is an important anchor point in corneal refractive surgery, which may affect by body position. This study investigated the feasibility of using a smartphone application in measurement of posture-related pupil center shifts. Methods: Images of undilated eyes were captured for 25 participants (age: 18-38 years) at a distance of 40 cm in four body positions (seated, supine, right lateral, and left lateral) under controlled lighting conditions. During taking images, a smartphone application was used to guide positioning without head rotation and tilt. From the images, the location of the pupil center and pupil diameter with respect to the limbus boundary were measured. Results: According to the data obtained by the smartphone application, pupil center was located slightly nasal and superior to the limbus center in the seated position, and it shifted more nasally and superiorly (p < 0.001, OD 0.54 ± 0.11 mm, OS 0.57 ± 0.14 mm) in the supine position. When body position switched between left and right lateral positions, the pupil centers of both eyes shifted along the direction of gravity (p < 0.05), and no significant shift occurred along the longitudinal axis. Moreover, pupil constriction was observed when the body position changed from seated to supine position (p < 0.001, OD 0.64 ± 0.57 mm, OS 0.63 ± 0.58 mm). Conclusion: Posture-related pupil center shift may be larger than the error tolerance of centration in corneal refractive surgery, which might be difficult to measure by the existing instruments. An accessible application is necessary for evaluating the shift of pupil center and guiding centration during the surgery.

Abstract
INTRODUCTION Menispermi Rhizoma (MR), the dried rhizome of Menispermum dauricum DC. (Menispermaceae), has been used to treat sore throat, enteritis, dysentery, and rheumatic arthralgia. Despite extensive research on its pharmacological effects, the chemical components in vitro and in vivo have not been thoroughly studied. OBJECTIVE To establish an efficient method for rapid classification and identification of alkaloids in MR and its preparations, as well as metabolites in vivo after oral administration of MR. METHODS Rapid identification of alkaloids and absorbed components of MR was performed using ultra-performance liquid chromatography quadrupole time-of-flight mass spectrometry (UPLC-Q-TOF-MS) coupled with UNIFI software. Moreover, the characteristic fragmentations and neutral losses of different types of alkaloids in MR were summarised to realise the rapid classification of alkaloids. RESULTS A total of 55 components were unambiguously or tentatively identified in MR. Among them, 37 and 31 components were found in MR capsules and tablets, respectively. Meanwhile, 109 compounds were tentatively identified in rat plasma, urine and faeces, including 55 prototypes and 54 metabolites. Hydrogenation, hydroxylation, methylation, glucuronic acid and sulphate conjugations were the dominating metabolic fates of alkaloids. CONCLUSION The data post-processing strategy established could greatly enhance the structural identification efficiency. The results obtained might lay the foundation for further interpretation of clinical effects, mechanism of action and quality control of MR.

Abstract
INTRODUCTION We performed a meta-analysis to evaluate the effect of intravesical mitomycin compared with gemcitabine on the treatment of non-muscle invasive bladder cancer. METHODS A systematic literature search up to November 2021 was done and 6 studies included 389 subjects with non-muscle invasive bladder cancer at the start of the study; 197 of them were provided with intravesical-mitomycin and 192 with intravesical gemcitabine. The studies reported the relationships about the effect of intravesical mitomycin compared with gemcitabine on the treatment of non-muscle invasive bladder cancer. We calculated the odds ratio (OR) with 95% confidence intervals (CIs) to assess the effect of intravesical mitomycin compared with gemcitabine on the treatment of non-muscle invasive bladder cancer using the dichotomous method with a random or fixed-effect model. RESULTS Intravesical mitomycin had significantly higher recurrence rates (OR, 2.41; 95% CI, 1.43-4.08, p=0.001) and chemical cystitis (OR, 4.39; 95% CI, 2.27-8.51, p<0.001) compared to intravesical gemcitabine in subjects with non-muscle invasive bladder cancer. However, intravesical mitomycin had no significant difference in its effect on hematuria (OR, 1.71; 95% CI, 0.68-4.33, p=0.26), skin reaction (OR, 2.04; 95% CI, 0.59-7.07, p=0.26), and liver and kidney functions damage (OR, 1.96; 95% CI, 0.35-10.96, p=0.44) compared to intravesical gemcitabine in subjects with non-muscle invasive bladder cancer. CONCLUSIONS Intravesical mitomycin had significantly higher recurrence rates and chemical cystitis and no significant difference in its effect on hematuria, skin reaction, and liver and kidney functions damage compared to intravesical gemcitabine in subjects with non-muscle invasive bladder cancer. Further studies are required to validate these findings.

Abstract
OBJECTIVE To study the role of apolipoprotein E (APOE) in regulating endometrial cancer metastasis and explore the signaling pathway in the regulatory mechanism. METHODS Human endometrial cancer cell line HEC-1B was transfected with a control siRNA (siCtrl) or a specific siRNA targeting APOE (siAPOE) or with either pEGFP-N1 plasmid or an APOEoverexpressing plasmid. The changes in migration, proliferation, apoptosis and cell cycle of the transfected cells were examined using wound healing assay, Transwell migration assay, MTT assay, flow cytometry, and Hoechst staining. The activity of the ERK/MMP9 signaling pathway in the transfected cells was assessed using RT-qPCR and Western blotting. The expression level of APOE in clinical specimens of endometrial cancer tissues were detected using immunohistochemistry and its correlation with differentiation of endometrial cancer tissues was analyzed. RESULTS Wound healing assay and Transwell migration assay showed that compared with those in siCtrl group, HEC-1B cells transfected with siAPOE showed significantly reduced migration ability (P < 0.05), whereas APOE overexpression significantly promoted the migration of the cells (P < 0.05). Neither APOE knockdown nor overexpression produced significant effects on HEC-1B cell proliferation as shown by MTT assay and flow cytometry. Hoechst staining revealed that transfection with siAPOE did not significantly affect apoptosis of HEC-1B cells. APOE knockdown obviously reduced and APOE overexpression enhanced ERK phosphorylation and MMP9 expression in HEC-1B cells (P < 0.05). Treatment with U0126 partially reversed the effects of APOE overexpression on ERK phosphorylation, migration and MMP9 expression in HEC-1B cells (P < 0.05). APOE is highly expressed in clinical samples of endometrial cancer tissues as compared with the adjacent tissues. CONCLUSION APOE is highly expressed in endometrial cancer tissues to promote cancer cell migration by enhancing ERK phosphorylation and MMP9 expression.

Abstract
To cope with the easy transmissibility of the avian influenza A virus subtype H1N1, a biosensor was developed for rapid and highly sensitive electrochemical immunoassay. Based on the principle of specific binding between antibody and virus molecules, the active molecule-antibody-adapter structure was formed on the surface of an Au NP substrate electrode; it included a highly specific surface area and good electrochemical activity for selective amplification detection of the H1N1 virus. The electrochemical test results showed that the BSA/H1N1 Ab/Glu/Cys/Au NPs/CP electrode was used for the electrochemical detection of the H1N1 virus with a sensitivity of 92.1 µA (pg/mL)-1 cm2, LOD of 0.25 pg/ml, linear ranges of 0.25-5 pg/mL, and linearity of (R 2 = 0.9846). A convenient H1N1 antibody-based electrochemical electrode for the molecular detection of the H1N1 virus will be of great use in the field of epidemic prevention and raw poultry protection.

Abstract
Perioperative traumatic stress is a systemic nonspecific response caused by stimuli such as anesthesia, surgery, pain and anxiety, which lasts throughout the perioperative period.The continuous excessive stress response is not conducive to the postoperative rehabilitation of patients. Enhanced recovery after surgery (ERAS), a research hotspot of modern surgery, can significantly reduce perioperative pain and stress, thus promoting the rehabilitation of patients. With the progress of artificial intelligence and information technology, wearable, non-invasive, real-time heart rate variability (HRV) dynamic monitoring can effectively realize the digitalization of stress monitoring with low price, which is worthy of clinical application. Therefore, the use of HRV for digital monitoring of perioperative stress has a significant research value. Moreover, the combination of HRV and ERAS has shown its advantages and the prospect of clinical application is worthy of anticipating.

Abstract
Objective: To explore the characteristics, clinical features and prognostic effects of NOTCH1/FBXW7 gene mutations in T-cell acute lymphoblastic leukemia (T-ALL) patients. Methods: The clinical data of 61 T-ALL patients who underwent second-generation gene sequencing in Henan Provincial People's Hospital from March 2016 to March 2021 were retrospectively analyzed. There were 46 males and 15 females, with a median age [M (Q1, Q3)] of 18 (11, 30) years. The relationship between NOTCH1/FBXW7 gene mutation characteristics, clinical and laboratory parameters and their impact on event free survival (EFS) and overall survival (OS) were analyzed. Results: NOTCH1 gene mutations were found in 34 cases (55.7%, 34/61), including 22 cases of heterodimer domain (HD) mutations (64.7%), 7 cases of proline/glutamate/serine/threonine (PEST) mutations (20.6%), and 5 cases of both HD and PEST mutations (14.7%). FBXW7 gene mutations were detected in 9 cases (14.8%, 9/61), of which 5 cases had both NOTCH1 and FBXW7 gene mutations. Twenty-three (37.7%, 23/61) cases were wild type. The median white blood cell count of patients in NOTCH1/FBXW7 gene mutations group and wild-type group was 76.4×109/L (8.3×109/L, 149.2×109/L), 54.1×109/L (5.3×109/L, 156.6×109/L), respectively. Moreover, the hemoglobin was (89.1±27.1) g/L and (99.5±23.1) g/L, respectively, and the median proportion of bone marrow primordial cells was 84.5% (69.0%, 91.3%) and 60.0%(35.0%, 80.0%), respectively. The gene expression rate of SIL-TAL1, Hox11 and Hox11L2 was 7.9% (3/38) vs 17.4% (4/23), 18.4% (7/38) vs 4.3% (1/23), 5.3% (2/38) vs 13.0% (3/23), respectively (all P>0.05). However, the median platelet level in the NOTCH1/FBXW7 gene mutations group was 60.5×109/L (36.8×109/L, 100.3×109/L), which was lower than that in the wild-type group [116.0×109/L (63.0×109/L, 178.0×109/L)] (P=0.018). The median number of gene mutations in the group with NOTCH1/FBXW7 gene mutations group was 2.5 (1.8, 4.0), which was more than that in the group without NOTCH1/FBXW7 gene mutations group [0 (0, 1.0)] (P<0.001). The median EFS and OS of adult NOTCH1/FBXW7 gene mutations group were 28.0 (95%CI: 7.3-48.7) months and 30.0 (95%CI: 8.9-51.1) months, respectively, which were better than those of adult wild-type group [4.5 (95%CI: 0-11.6) months and 9.0 (95%CI: 0-19.1) months] (P=0.008 and 0.014).The median EFS and OS of children NOTCH1/FBXW7 gene mutations group were 12.0 (95%CI: 10.4-13.6) months and 19.0 (95%CI: 13.6-24.4) months, respectively, and those of wild-type group were 10.0 (95%CI: 8.9-11.1) months and 21.0 (95%CI: 0-51.4) months, respectively (P=0.673 and 0.434). Conclusions: The mutation rate of NOTCH1/FBXW7 gene is higher in T-ALL patients. Patients with NOTCH1/FBXW7 gene mutations group have lower platelet count and better EFS and OS. NOTCH1/FBXW7 gene mutation may be used as a hierarchical basis for individualized treatment of adult T-ALL patients.

Abstract
Objective: To evaluate the efficacy and safety of laparoscopic surgery for perivascular epithelioid cell tumor (PEComa). Methods: The clinical data of 42 patients with hepatic PEComa diagnosed by pathology in Hunan Provincial People's Hospital from September 2012 to September 2021 were retrospectively analyzed. The patients were divided into the endoscopic group and the open group according to surgical methods. Statistical software was used to compare the differences in operation time, intraoperative blood loss, postoperative hospital stay, postoperative pathological data and incidence of complications between the two groups. Results: There were 27 cases in the endoscopic group and 15 cases in the open group. In the endoscopic group, there were 5 males and 22 females, aged (40.0±10.4) years. In the open group, there were 5 males and 10 females, aged (44.5±12.6) years. The operative time of the endoscopic group and the open group was (239±156.2) min and (348±103.0) min, and the postoperative hospital stay was (8.2±2.4) d and (13.7±4.9) d, respectively, the endoscopic group was significantly better than the open group, and the difference was statistically significant (P<0.05). There was no significant difference in intraoperative blood loss, tumor benign and malignant, tumor site, tumor diameter, Ki67 index, postoperative complications such as biliary leakage, incision infection and pleural effusion (P>0.05). During the follow-up period of 2-103 months, one case was lost to follow-up, two cases died in the endoscopic group,one case died in the open group. The 5-year overall survival rate (OS) and disease-free survival rate (DFS) were 80.8% and 83.0%, respectively. Meanwhile,. The 5-year OS and DFS were both 92.3%, the difference was not statistically significant (P>0.05). Conclusions: Laparoscopic treatment of hepatic PEComa has the advantages of short operation time and short postoperative hospital stay, and the incidence of complications, 5-year OS and DFS are not significantly different from that of the open group.

Abstract
Objective: To investigate the epidemiological characteristics of COVID-19 caused by 2019-nCoV Delta variant in Shangyu district, Shaoxing of Zhejiang province in 2021, and provide evidence for the improvement of COVID-19 control and prevention measures. Methods: The incidence data of COVID-19 in Shangyu from December 7 to 21, 2021 was obtained from Shangyu District Center for Disease Control and Prevention. The epidemiological characteristics of the cases, i.e. the population, time and space distributions, were analyzed, and the incubation period and time-varying reproduction numbers (Rt) were calculated. Results: From December 7 to 21, 2021, a total of 380 COVID-19 cases caused by 2019-nCoV Delta variant were detected in Shangyu, the median age of the cases was 52 years, M (Q1,Q3: 38, 61). The male to female ratio of the cases was 1∶1.25, and the cases were mainly workers (36.58%) and farmers (27.63%). The epidemic affected 9 townships (or community) of Shangyu, especially Caoe and Baiguan communities with the cases accounting for 57.10% and 31.53% respectively. The median incubation period of cases was 4.00 days, M (Q1,Q3: 3.00, 5.75). The basic reproduction number (R0) was 4.06, and the Rt was 5.62 in early phase of the outbreak (the highest) and continuously decreased to less than 1.00 within 10 days after the detection of the outbreak. The number of COVID-19 cases decreased to 0 within 14 days after the outbreak (December 7-21), and the main detection methods were screening in centralized isolation (55.53%) and home isolation (40.00%). The infection rates of close contacts and secondary close contacts were 2.06% and 0.46% respectively. Conclusion: The epidemic of COVID-19 in Shangyu characterized by short incubation period, large number of infected people, and case clustering, suggesting the strong transmission of Delta variant (B.1.617.2). Comprehensive prevention and control measures, such as management of close contacts and secondary close contacts, and high-risk area, are essential for the rapid control of the epidemic.

Abstract
Objective: To assess the efficacy and safety of Saccharomyces boulardii (S. boulardii) in combination with triple therapy as a first-line regimen for the eradication of Helicobacter pylori (H. pylori) in non-ulcer dyspepsia (NUD) patients. Methods: A total of 497 Helicobacter pylori-positive patients who underwent gastroscopy and diagnosed with NUD were enrolled from June 2018 to January 2020 in 9 medical centers across China. Participants were segmentedly randomly divided into 3 groups. Patients in group A received S. boulardii for 14 days and triple therapy for 10 days, while patients in group B received bismuth quadruple group for 10 days, and patients in group C received triple therapy for 10 days. The H. pylori status was determined by the 13C-urea breath test on the 44th day of the treatment. Symptom improvement and adverse reactions were assessed on the 14th and 44th day. Results: There were 229 males and 268 females in all 497 patients enrolled. They were aged 18-69 (46.1±11.8) years and 472 of them (158 cases in group A, 159 cases in group B, and 155 cases in group C) completed the trial. The intention-to-treat (ITT) eradication rates in patients in patients A, B and C were 77.8% (126/162), 80.1% (137/171) and 65.2% (107/164) respectively, and per protocol-based (PP) eradication rates were 79.7% (126/158), 86.2% (137/159) and 69.0% (107/155) respectively. The differences were statistically significant in ITT and PP analysis among 3 groups (ITT: χ²=11.14, P<0.01; PP: χ²=13.86, P<0.01). There was no significant difference between eradication rates of two quadruple therapys(all P>0.05), but both of them were significantly higher than that of standard triple therapy (both P<0.05). Statistics revealed that both quadruple therapys led to significantly higher symptom improvement of belching compared with that of standard triple therapy in day 14 (P<0.05). The relief of abdominal distension and belching symptom scores of group A were significantly higher than those of group C in day 44(all P<0.05). There was no serious adverse event reported. The incidence of diarrhea in group A was significantly lower than those in the other two groups (both P<0.05). Conclusions: The combination of S. boulardii and triple therapy can achieve a better eradication effect on H. pylori infection with NUD, and has advantages in symptom relief and safety.

Abstract
Objective: To investigate the influenza and pneumonia vaccination rates in patients with chronic obstructive pulmonary disease (COPD), and analyze the factors affecting vaccination. Methods: Totally 4 016 COPD patients at the initial visit were included in the Respiratory Department of Xiangya Second Hospital of Central South University from December, 2016 to December, 2019. Each patient's vaccination status after the visit for 1 year was reviewed, and finally 3 177 patients were included in the analysis. Relevant factors affecting vaccination were analyzed with logistic regression. Results: The overall vaccination rates of COPD patients with influenza vaccine, pneumonia vaccine and influenza combined pneumonia vaccine were 2.3% (72/3 177), 1.1% (34/3 177) and 1.1% (34/3 177), respectively. The influenza vaccination rate of urban patients (3.3%, 41/1 252) was higher than that of rural patients (1.6%, 31/1 925,P=0.002). The rates of influenza vaccine, pneumonia vaccine and influenza combined pneumonia vaccine in ex-smokers with COPD were 3.3% (33/993), 2.1% (21/993), 2.1% (21/993), respectively and 1.7% (25/1 467), 0.7% (11/1 467), 0.7% (11/1 467), in current smokers with COPD, respectively (P=0.034, P=0.015, P=0.015, respectively). The influenza vaccination rate was higher in patients with COPD assessment test (CAT) scored less than 10 (4%, 27/673) than patients with CAT scored more than 10 (1.8%, 45/2 504,P=0.002). In a multifactor analysis, patients who lived in country side, were current smokers, and had more symptoms were less likely to be vaccinated, with an aOR 1.73(95%CI 1.02-2.93), 2.10(95%CI 1.18-3.76), 2.06(95%CI 1.24-3.43), respectively. 81.2% of COPD patients did not receive the vaccine because they did not know the vaccine. Conclusions: Vaccination rates for influenza vaccine, pneumonia vaccine and both of them in COPD patients were low and the patients lacked knowledge of vaccine. The residence, smoking status and symptoms were related to the vaccination of COPD patients, and these should be taken into account in the vaccination health education.

Abstract
Purpose The purpose of this study was to evaluate the potential feasibility of using a smartphone app in myopia screening. Methods The app estimates myopic refractive error by measuring the far point distance for reading three 20/20 Tumbling E letters. In total, 113 myopic subjects with astigmatism no greater than -1.75 diopters (D) were enrolled from 5 sites. The mean age was 22 ± 8.5 years. The app measurement was compared with noncycloplegic subjective refraction measurement or autorefractor if subjective refraction was not available. In addition, 22 subjects were tested with the app for repeatability. Results For 201 eyes included, the range of spherical equivalent refraction error was 0 to -10.2 D. The app measurement and clinical measurement was highly correlated (Pearson R = 0.91, P < 0.001). There was a small bias (0.17 D) in the app measurement overall, and it was significantly different across the 5 sites due to different age of subjects enrolled at those sites (P = 0.001) - young adults in their 20s were underestimated the most by 0.49 D, whereas children were overestimated by 0.29 D. The mean absolute deviation of the app measurement was 0.65 D. The repeatability of multiple testing in terms of 95% limit of agreement was ±0.61 D. Conclusions Overall, the app measurement is consistent with clinical measurement performed by vision care professionals. The repeatability is comparable with that of some autorefractors. Age-associated human factors may influence the app measurement. Translational Relevance The app could be potentially used as a mass screening tool for myopia.

Abstract
PURPOSE This study aimed to investigate the prevalence and risk factors for myopia and high myopia among Han and Uyghur students in Xinjiang, China. METHODS This cross-sectional study with a multistage, stratified cluster sampling method was completed in Xinjiang, China. Visual acuity and noncycloplegic refraction were measured. The crude and sex- and age-adjusted prevalence of myopia and high myopia in Han and Uyghur students were compared. Multivariate logistic regression analyses were applied to identify risk factors associated with myopia and high myopia. RESULTS In total, 84,033 participants were included in the final analysis, comprising 64,110 Han and 19,923 Uyghur participants. The overall age- and sex-adjusted prevalence of myopia and high myopia were 47.70% (95% CI: 47.67-47.74) and 2.55% (95% CI: 2.54-2.56), respectively. Compared to the Uyghur population, the Han population had a higher prevalence of myopia (63.59% vs. 21.34%, p < 0.0001) and high myopia (4.68% vs. 0.6%, p < 0.0001). Han ethnicity, age, female sex, higher education level and living in urban areas were found to be positively associated with myopia and high myopia. Living in northern Xinjiang was found to be positively associated with myopia but negatively associated with high myopia. CONCLUSIONS Our study investigated the prevalence of myopia and high myopia among Han and Uyghur students aged 4-23 years in Xinjiang, China. The Han population had a higher prevalence of myopia and high myopia than the Uyghur population. However, the prevalence of myopia among the Uyghur population showed a more remarkable increasing trend than that among the Han population in Xinjiang.

Abstract
The rapid development of industrial technologies continuously increases the heavy metal pollution of water resources. Recently, portable electrochemical analysis-based devices for detecting heavy metal ions have attracted much attention due to their excellent performance and low fabrication costs. However, it has proven difficult to accommodate complex testing needs in a cost-effective manner. To address these limitations, we propose a new system for the in situ detection of heavy metals in wastewater using an organic light-emitting diode-based panel to display data in real time and Bluetooth to transmit data to a smartphone for rapid analysis. The fabricated device integrates an in situ signal analysis circuit, a Bluetooth chip, a photocured 3D-printed shell, and an electrode sleeve interface. In addition, a fully screen-printed functional electrode plate containing chitosan/PANi-Bi nanoparticle@graphene oxide multi-walled carbon nanotubes is utilized for the rapid detection of heavy metal ions. This device can perform wireless data transmission and analysis and in situ signal acquisition and processing. The sensor exhibits a high sensitivity (Hg2+: 88.34 μA ppm-1 cm-2; Cu2+: 0.956 μA ppm-1 cm-2), low limit of detection (Hg2+: 10 ppb, Cu2+: 0.998 ppm) and high selectivity during the detection of copper and mercury ions in tap water under non-laboratory conditions, and the results of real-time tests reveal that parameters measured in the field and laboratory environments are identical. Hence, this small, portable, electrochemical sensor with a screen-printed electrode can be effectively used for the real-time detection of copper and mercury ions in complex water environments.

Abstract
OBJECTIVE In our previous genomic studies in human intracranial aneurysms, we observed downregulations in the expression of a number of ribosomal protein genes and the c-Myc-related gene MYC target 1 (MYCT1). So far there is no information about the roles of MYCT1 in vascular cells. Our study aims to investigate the functional roles of MYCT1 in vascular smooth muscle cells (SMCs). MATERIALS AND METHODS Primary SMCs were isolated from rat thoracic aorta and cultured in vitro. The mRNA and protein expressions were determined by real-time PCR and western blot respectively. Apoptosis was detected by measuring caspase 3/7 activity. Collagen production was determined with ELISA. RESULTS Using PCR, we validated our previous genomic data showing that the expressions of MYCT1 and ribosomal protein genes were decreased in human aneurysm tissues. In vascular SMCs, we showed that nitrosative stress downregulated the expression of both MYCT1 and ribosomal proteins. Knockdown of MYCT1 mimicked the effects of nitrosative stress on ribosomal protein expressions, whereas overexpression of MYCT1 blunted the effects of nitrosative stress. MYCT1-dependent downregulation of ribosomal proteins compromised the protein translational capacity of the cells for collagen production. Moreover, the endogenously expressed MYCT1 in vascular SMCs was involved in maintaining normal cellular functions including survival, proliferation and migration. CONCLUSIONS MYCT1-dependent gene regulation may, at least partly, explain the downregulated expressions of ribosomal proteins observed in human intracranial aneurysms. It is suggested that MYCT1 may represent a novel molecular target for counteracting the decreased activity of aneurysmal SMCs for tissue repairmen/regeneration.

Abstract
With the continuous development of DNA nanotechnology, various spatial DNA structures and assembly techniques emerge. Hybridization chain reaction (HCR) is a typical example with exciting features and bright prospects in biosensing, which has been intensively investigated in the past decade. In this Spotlight on Applications, we summarize the assembly principles of conventional HCR and some novel forms of linear/nonlinear HCR. With advantages like great assembly kinetics, facile operation, and an enzyme-free and isothermal reaction, these strategies can be integrated with most mainstream reporters (e.g., fluorescence, electrochemistry, and colorimetry) for the ultrasensitive detection of abundant targets. Particularly, we select several representative studies to better illustrate the novel ideas and performances of HCR strategies. Theoretical and practical utilities are confirmed for a range of biosensing applications. In the end, a deep discussion is provided about the challenges and future tasks of this field.

Abstract
We report a measurement of the observed cross sections of e^{+}e^{-}→J/ψX based on 3.21 fb^{-1} of data accumulated at energies from 3.645 to 3.891 GeV with the BESIII detector operated at the BEPCII collider. In analysis of the cross sections, we measured the decay branching fractions of B(ψ(3686)→J/ψX)=(64.4±0.6±1.6)% and B(ψ(3770)→J/ψX)=(0.5±0.2±0.1)% for the first time. The energy-dependent line shape of these cross sections cannot be well described by two Breit-Wigner (BW) amplitudes of the expected decays ψ(3686)→J/ψX and ψ(3770)→J/ψX. Instead, it can be better described with one more BW amplitude of the decay R(3760)→J/ψX. Under this assumption, we extracted the R(3760) mass M_{R(3760)}=3766.2±3.8±0.4 MeV/c^{2} , total width Γ_{R(3760)}^{tot}=22.2±5.9±1.4 MeV, and product of leptonic width and decay branching fraction Γ_{R(3760)}^{ee}B[R(3760)→J/ψX]=(79.4±85.5±11.7) eV. The significance of the R(3760) is 5.3σ. The first uncertainties of these measured quantities are from fits to the cross sections and second systematic.

Abstract
目的 探讨Ph阳性附加染色体异常(ACA/Ph+)对初诊慢性期(CP)和治疗中进展为加速期和急变期慢性髓性白血病(CML-AP/BP)患者生物学特征、疗效和预后的影响。 方法 回顾性分析2013年1月至2020年6月河南省人民医院收治的410例Ph+ CML[初诊CML-CP 348例,治疗中进展为AP/BP(进展期CML)62例]患者的临床资料,根据ELN2020标准将其分为高危、非高危和无ACA/Ph+三组,并比较分析高危/非高危ACA/Ph+对其生物学特征、疗效和预后的影响。 结果 ①348例初诊CML-CP患者,合并ACA/Ph+者20例(5.75%),其中高危ACA/Ph+组3例,非高危ACA/Ph+组17例;无ACA/Ph+组328例。伴ACA/Ph+和无ACA/Ph+组患者的基本临床特征差异无统计学意义(P值均>0.05);非高危ACA/Ph+组和无ACA/Ph+组间完全血液学缓解(CHR)率、完全细胞遗传学反应(CCyR)率、主要分子学反应(MMR)率和5年总生存(OS)率差异均无统计学意义(P值均>0.05);非高危ACA/Ph+组5年无进展生存(PFS)率显著低于无ACA/Ph+组(42.0%对74.5%,χ2=4.766,P=0.029)。②62例进展期CML患者,合并ACA/Ph+者41例(66.13%),其中高危ACA/Ph+组28例,非高危ACA/Ph+组13例;无ACA/Ph+组21例。高危ACA/Ph+组患者中位PLT水平(42.5×109/L)低于非高危(141×109/L)和无ACA/Ph+组(109×109/L)(χ2=4.968,P=0.083);三组间ABL激酶区点突变发生率差异无统计学意义(P=0.652)。高危ACA/Ph+组CCyR率显著低于无ACA/Ph+组(5.3%对46.7%,χ2=5.851,P=0.016)。高危ACA/Ph+组5年OS率为46.2%,非高危ACA/Ph+组为64.3%,无ACA/Ph+组为77.8%,其中高危ACA/Ph+组患者5年OS率明显低于无ACA/Ph+组(χ2=3.878,P=0.049)。亚组分析显示高危Ⅰ组(+8,+Ph或含+8/+Ph的复杂ACA)CML患者的5年OS率为54.5%,与无ACA/Ph+组相比差异无统计学意义(χ2=1.514,P=0.219);高危Ⅱ组[含−7/7q−或i(17q)或含2个及以上高危ACA的复杂核型]为28.6%,显著低于无ACA/Ph+组(χ2=8.035,P=0.005)。 结论 因ACA类型和疾病分期不同,伴ACA/Ph+ CML患者的治疗反应和预后存在差异,治疗过程中高危ACA的出现意味着更差的治疗反应和预后,严格、规范的细胞遗传学监测对此类患者的早期发现和精准诊疗具有重要意义。

Abstract
OBJECTIVE To investigate the expression and clinicopathological significance of Bcl-2 and Bax genes in colorectal cancer (CRC) patients complicated with schistosomiasis. METHODS The CRC patients receiving surgical treatment in the First Affiliated Hospital of Dali University from June 2016 to June 2020 were recruited as the study subjects, and 30 subjects were randomly sampled from the CRC patients complicated with schistosomiasis (CRC-S group) and 30 subjects were randomly sampled from the CRC patients without schistosomiasis (CRC group) using a random number table method. The cancer specimens were sampled from subjects in the CRC-S and CRC groups, and the peri-cancer specimens were sampled from subjects in the CRC group. The Bcl-2 and Bax expression was quantified in cancer and peri-cancer specimens using a real-time fluorescent quantitative PCR (qPCR) assay and immunohistochemistry at transcriptional and translational levels, and the cell apoptosis was detected in cancer specimens using HE staining. RESULTS A total of 60 subjects were enrolled, including 30 cases in the CRC group and 30 cases in the CRC-S group. There were no significant differences between the two groups in terms of gender distribution (χ2 = 0.271, P > 0.05), mean age (t = -0.596, P > 0.05), tumor growth pattern (χ2 = 0.275, P > 0.05), tumor location (χ2 = 4.008, P > 0.05), tumor invasion depth (χ2 = 0.608, P > 0.05), degree of tumor differentiation (χ2 = 0.364, P > 0.05), or presence of vascular metastasis (χ2 = 1.111, P > 0.05), while significant differences were seen between the two groups in terms of histological type, presence of lymph node metastasis and TMN staging (χ2 = 5.963, 8.297 and 5.711, all P values < 0.05). qPCR assay and immunohistochemistry quantified significantly higher Bcl-2 and Bax expression in cancer specimens from the CRC and CRC-S groups than in the peri-cancer specimens from the CRC group at both translational and transcriptional levels (all P values < 0.05), and higher Bcl-2 and lower Bax expression were seen in the cancer specimens from the CSC-S group than that from the CRC group (all P values < 0.05). In addition, the cell apoptotic rate was significantly greater in the cancer specimens in the CRC group than in the CRC-S group (42.00% vs. 23.35%; χ2 = 41.500, P = 0.000). CONCLUSION Schistosomiasis may be involved in the development and progression of CRC through affecting Bcl-2 and Bax gene expression in the apoptosis signaling pathway.

Abstract
Background Strabismus is the leading risk factor for amblyopia, which should be early detected for minimized visual impairment. However, traditional school screening for strabismus can be challenged due to several factors, most notably training, mobility and cost. The purpose of our study is to evaluate the feasibility of using a smartphone application in school vision screening for detection of strabismus. Methods The beta smartphone application, EyeTurn, can measure ocular misalignment by computerized Hirschberg test. The application was used by a school nurse in a routine vision screening for 133 elementary school children. All app measurements were reviewed by an ophthalmologist to assess the rate of successful measurement and were flagged for in-person verification with prism alternating cover test (PACT) using a 2.4Δ threshold (root mean squared error of the app). A receiver operating characteristic (ROC) curve was used to determine the best sensitivity and specificity for an 8Δ threshold (recommended by AAPOS) with the PACT measurement as ground truth. Results The nurse obtained at least one successful app measurement for 93% of children (125/133). 40 were flagged for PACT, of which 6 were confirmed to have strabismus, including 4 exotropia (10△, 10△, 14△ and 18△), 1 constant esotropia (25△) and 1 accommodative esotropia (14△). Based on the ROC curve, the optimum threshold for the app to detect strabismus was determined to be 3.0△, with the best sensitivity (83.0%), specificity (76.5%). With this threshold the app would have missed one child with accommodative esotriopia, whereas conventional screening missed 3 cases of intermittent extropia. Conclusions Results support feasibility of use of the app by personnel without professional training in routine school screenings to improve detection of strabismus.
