Abstract
Piezochromic materials that exhibit pressure-dependent luminescence variations are attracting interest with wide potential applications in mechanical sensors, anticounterfeiting and storage devices. Crystalline porous materials (CPMs) have been widely studied in piezochromism for highly tunable luminescence. Nevertheless, reversible and high-contrast emission response with a wide pressure range is still challenging. Herein, the first example of hierarchical porous cage-based πOF (Cage-πOF-1) with spring structure was synthesized by using aromatic chiral cages as building blocks. Its elastic properties evaluated based on the bulk modulus (9.5 GPa) is softer than most reported CPMs and the collapse point (20.0 GPa) significantly exceeds ever reported CPMs. As smart materials, Cage-πOF-1 displays linear pressure-dependent emission and achieves a high-contrast emission difference up to 154 nm. Pressure-responsive limit is up to 16 GPa, outperforming the CPMs reported so far. Dedicated experiments and density functional theory (DFT) calculations illustrate that π-π interactions-dominated controllable structural shrinkage and porous-spring-structure-mediated elasticity is responsible for the outstanding piezofluorochromism.

Abstract
PURPOSE Maternal hyperandrogenism during pregnancy is associated with adverse gestational outcomes and chronic non-communicable diseases in offspring. However, few studies are reported to demonstrate the association between maternal androgen excess and cardiac health in offspring. This study aimed to explore the relation between androgen exposure in utero and cardiac health of offspring in fetal and adult period. Its underlying mechanism is also illustrated in this research. METHODS Pregnant mice were injected with dihydrotestosterone (DHT) from gestational day (GD) 16.5 to GD18.5. On GD18.5, fetal heart tissue was collected for metabolite and morphological analysis. The hearts from adult offspring were also collected for morphological and qPCR analysis. H9c2 cells were treated with 75 μM androsterone. Immunofluorescence, flow cytometry, qPCR, and western blot were performed to observe cell proliferation and explore the underlying mechanism. RESULTS Intrauterine exposure to excessive androgen led to thinner ventricular wall, decreased number of cardiomyocytes in fetal offspring and caused cardiac hypertrophy, compromised cardiac function in adult offspring. The analysis of steroid hormone metabolites in fetal heart tissue by ultra performance liquid chromatography and tandem mass spectrometry showed that the content of androgen metabolite androsterone was significantly increased. Mechanistically, H9c2 cells treated with androsterone led to a significant decrease in phosphorylated retinoblastoma protein (pRB) and cell cycle-related protein including cyclin-dependent kinase 2 (CDK2), cyclin-dependent kinase 4 (CDK4), and cyclin D1 (CCND1) in cardiomyocytes. This resulted in cell cycle arrest at G1-S phase, which in turn inhibited cardiomyocyte proliferation. CONCLUSION Taken together, our results indicate that in utero exposure to DHT, its metabolite androsterone could directly decrease cardiomyocytes proliferation through cell cycle arrest, which has a life-long-lasting effect on cardiac health. Our study highlights the importance of monitoring sex hormones in women during pregnancy and the follow-up of cardiac function in offspring with high risk of intrauterine androgen exposure.

Abstract
CYP 3A4 and CYP 3A5 are two important members of the human cytochrome P450 family. Although their overall structures are similar, the local structures of the active site are different, which directly leads to obvious individual differences in drug metabolic efficacy and toxicity. In this work, midazolam (MDZ) was selected as the probe substrate, and its interaction with two proteins, CYP 3A4 and CYP 3A5, was studied by molecular dynamics simulation (MD) along with the calculation of the binding free energy. The results show that two protein-substrate complexes have some similarities in enzyme-substrate binding; that is, in both complexes, Ser119 forms a high occupancy hydrogen bond with MDZ, which plays a key role in the stability of the interaction between MDZ and the enzymes. However, the complex formed by CYP 3A4 and MDZ is more stable, which may be attributed to the sandwich structure formed by the fluorophenyl group of the substrate with Leu216 and Leu482. Our study interprets the binding differences between two isoform-substrate complexes and reveals a structure-function relationship from the atomic perspective, which is expected to provide a theoretical basis for accurately measuring the effectiveness and toxicity of drugs for individuals in the era of precision medicine.

Abstract
PURPOSE/OBJECTIVE(S) The purpose of this study was to investigate whether the bladder volume of patients with pelvic tumor treated with radiotherapy (RT) can be accurately measured using the Meike Palm Bladder Scanner PBSV3.2 manufactured in China and the accuracy of its measurement under different influencing factors. MATERIALS/METHODS One hundred and sixty-five patients with pelvic tumor radiotherapy who were positioned in our department from January 12, 2022, to July 7, 2022, were selected. All patients voided their bowels and urine one hour before positioning, had a gynecological examination, were instructed to drink 500-800 ml of water, urine volume was measured using PBSV3.2 when they felt the urge to urinate, and urine volume reached 150-350 ml given for positioning (20 minutes expected from making the film appliance to the end of positioning), and the data were measured and recorded using a cystometric device immediately after positioning. The CT bladder volume outlined by the treating physician is viewed in the planning system. The accuracy of PBSV3.2 was evaluated by comparing the bladder volume measured by the bladder scanner and CT. To investigate the accuracy of PBSV3.2 in different sex, ages, treatment purpose, and bladder volume. RESULTS There was a significant positive correlation with bladder volume on CT and PBSV (r = 0.874; p<0.001). The mean difference between CT measured values and PBSV was (-0.14±50.17) ml. The results of the different variables showed that the overall mean of PBSV and CT measurements were statistically different in the age ≥65 years, bladder volumes >400ml and ≤400ml groups (p = 0.028, 0.002, 0.001). There was no statistical significance between the remaining variables. The volume difference between PBSV measurement and CT was 12.87ml in male patients, which was larger than that in female patients 3.27ml. Pearson correlation analysis showed that the correlation coefficient was 0.473 for bladder volume greater than 400ml and 0.868 for bladder volume less than 400ml; the correlation coefficient of the other variables ranged from 0.802 to 0.893. CONCLUSION This is the first large-sample study to evaluate the accuracy of PBSV in a pelvic tumor RT population using the convenient bladder scanner PBSV3.2 made in China. PBSV provides an acceptable indicator for monitoring bladder volume in patients with pelvic RT. It is recommended to monitor bladder volume with PBSV when the planned bladder volume is 200-400ml. For male and patients ≥65 years old, at least two repeat measurements are required when using a bladder scanner and the volume should be corrected by using a modified feature to improve bladder volume consistency.

Abstract
PURPOSE/OBJECTIVE(S) The primary liver cancer radiation therapy 4D-CT-enhanced (CE-4DCT) scan can accurately reflect the state of the liver as it moves with respiration, and enables clear visualization of the tumor, providing a precise range for target area outlining. However, the CE-4DCT scan localization time of primary liver cancer is long, and the fixed delay time of diagnostic CT cannot obtain high-quality 4DCT images. To this end, we designed a randomized controlled study to investigate the ideal localization scan delay time parameters for primary liver cancer CE-4DCT. MATERIALS/METHODS Patients with primary hepatocellular carcinoma who presented to our department for radiotherapy CT localization from January to December 2022 participated in this study. All subjects were randomly divided into two groups in a 1:1 ratio. CE-4DCT scans were performed using a high concentration of iodomepril (400 mg/ml) contrast agent with a contrast volume equal to the patient's body weight. The scanning parameters were set according to scheme A (flow rate 2.0 ml/s, delay time 30s) and B (2.0 ml/s, 35s) respectively. Before the CE-4D CT scan, CT plain scan was routinely performed, physicians measured the CT value (HU) of abdominal aorta, portal vein, left hepatic vein, middle hepatic vein, right hepatic vein, liver parenchyma and tumor lesion on CT40 time item and plain scan images respectively. The image quality was subjectively and qualitatively assessed. The image enhancement effect is divided into excellent, good, relatively poor and poor. RESULTS A total of 18 patients were included in this study. Patient characteristics were well-balanced in both groups. There were statistical differences between the two groups (A vs B) in the abdominal aorta (226.66 ± 45.59 vs. 176.66 ± 32.84, p = 0.017), left hepatic vein (142.77 ± 24.41 vs. 164.88 ± 19.02, p = 0.048); in the portal vein, middle hepatic vein, right hepatic vein, liver parenchyma, and tumor lesions CT values were not statistically different. The comparison of all flat-scan images between the two groups was statistically significant. The comparison of all flat-scan images in both groups was statistically significant. The subjective qualitative assessment of the developing effect was excellent in 44.4% (33.3% vs. 11.1%), good in 16.7% (5.6% vs. 11.1%), and poor in 38.9% (16.7% vs. 22.2%) in both groups. image quality was slightly higher in group A than in group B, but did not reach statistical significance (χ2 = 1.088, p = 0.698). In patients with primary hepatocellular carcinoma with portal vein carcinoma thrombosis 83.33% subjectively evaluated poor results. CONCLUSION Qualitatively acceptable enhanced images were obtained for primary hepatocellular carcinoma (CE-4DCT) localization scans with a delay time controlled at 30s when using the least amount of contrast agent and the same flow rate.

Abstract
PURPOSE/OBJECTIVE(S) Cervical cancer (CC) is a tumor disease that threatens the health of women. As an important treatment of CC, radiotherapy has been widely used in clinic. With the rapid development of radiotherapy technology, adaptive radiotherapy has received much attention. Adaptive radiotherapy means more accurate radiation dose and more accurate radiation area, which can effectively protect normal tissue. It is significant to improve the local control rate of tumor and the quality of life of patients. However, the Cone-Beam CT (CBCT) images collected during radiotherapy are of poor quality and cannot provide real-time radiation effect information, resulting in timely and effective adjustment of radiation dose and radiation area in the process of radiotherapy for cervical cancer. To alleviate this issue, this study will establish a model to leverage CC CBCT images to synthetize pseudo computed tomography (CT) images with high quality, so as to achieve the purpose of quality improvement. MATERIALS/METHODS This study included the data of 20 patients with CC in ** hospital. The planning CT and CBCT scan data of each patient before radiotherapy were collected, and the interval between the two kinds of image data was required to be less than one week. After data preprocessing, a total of 1206 pairs of images were trained and tested. The generative adversarial network (GAN) is constructed. In order to ensure the similarity between the input image and the output image, the L1 loss function is leveraged. And the full supervision method is used to train the model to achieve a better effect of image synthesis and improve the quality of CBCT image. Peak signal-to-noise ratio (PSNR) and structural similarity (SSIM) were used as evaluation indexes. RESULTS Using five-fold cross-validation, the values of PSNR between the pseudo-CT (sCT) and the planning CT (pCT) image and between the CBCT and the pCT image are calculated. The results are 26.9 and 22.6, respectively. The sCT obtained from the GAN model increases the peak signal-to-noise ratio by 19% compared with the original CBCT, which means that the proposed model built in this study can improve the useful information of the CBCT image. The SSIM values between sCT and pCT and between CBCT and pCT are also calculated, and the average values of them are 0.89 and 0.63, respectively. Therefore, in this experiment, the structure of the sCT obtained by the proposed model is closer to pCT. And the SSIM increases by 41.2% compared with the original CBCT, which means that the sCT by the proposed model is more similar to the pCT in structure. These results could make a more accurate judgment on the effect of radiotherapy. CONCLUSION In this study, the pseudo-CT synthesis method based on GAN can improve the quality of CC CBCT image. The results show this method makes the structure clearer and could assist doctors to adjust the radiation dose and radiation area in time. This study is able to facilitate the development of adaptive radiotherapy for CC.

Abstract
PURPOSE/OBJECTIVE(S) Thermoplasticfilm routinely placed in the treatment room always led to uncomfortable feeling in patients receiving thorax radiation therapy because of significant temperature difference between thermoplastic film and body surface. Therefore, it may result in setup error and further affect accuracy of radiation therapy. Here, we designed a randomized controlled study to investigate the efficacy of preheat thermoplastic film to reduce setup error in patients receiving thorax radiotherapy. MATERIALS/METHODS Patients with thoracic cancer receiving radiotherapy once daily with five fraction per week were enrolled in this study from October 2022 to January 2023. All participants were randomly assigned into room-temperature group and preheating group in a 1:1 ratio. For the preheating group, the thermoplastic film was preheated for 10 minutes in a 37°C thermostat before it was used for patients' setup. For controlled group, the thermoplastic film with room-temperature was used for patients' setup. The cone beam computed tomography (CBCT) was used to evaluate setup errors once a week. The setup errors in translational directions X, Y and Z were recorded based on CBCT image. to measure the left-right as well as anterior-posterior diameter of the thorax in cross-section to observe whether there was any difference in thorax size from that at positioning. A modified Likert questionnaire was conducted to investigate the setup comfort level between two groups before radiotherapy and Day 5 of radiotherapy. RESULTS A total of 34 patients were enrolled in this study. Patient characteristics were well balanced in both arms. The setup errors in the X, Y, and Z axes in group A were 1(-1,1) mm, 0(-1,2.75) mm and 0(-1,1) mm, respectively, while those in group B were 0(-2,2) mm, 1(-1.25,3) mm, and -1(-2,1) mm in the X, Y, and Z axes, respectively. Setup error in preheating group was smaller than room-temperature group in the X-axis direction (Z = 2.04, P = 0.042), but no significant differences were detected in Y and Z axes. Comparison of changes in anteroposterior thoracic diameter between the two groups. The preheated group was smaller than the normothermic group (-0.19 ± 0.48 vs -0.38 ± 0.36, P < 0.01). The total comfort scale scores of the two groups were 30.88 ± 3.39 vs 30.59 ± 3.34 (p = 0.42) before treatment and 32.125 ± 4.31 vs 31.06 ± 3.15 (p = 0.80) after treatment. Among the eight sub-items, only the fourth dimension of temperature was statistically different (pre 3.12 ± 0.48 vs 2.88 ± 0.60, P = 0.218; post 4.12 ± 0.78 vs 2.94 ± 0.43, P < 0.01). CONCLUSION Ourcenter proposed the first method of heating the mold for postural fixation during patient radiotherapy. Compared with room-temperature thermoplastic film, our study found preheating thermoplastic film with 37°C could significantly reduce setup error in the X direction with less effect on the anterior-posterior diameter change of the thorax and higher patient temperature comfort satisfaction.

Abstract
Single-atom nanozymes (SANs) have attracted great attention in constructing devices for instant biosensing due to their excellent stability and atom utilization. Here, Mo atoms were immobilized in 2D nitrogen-doped carbon films by cascade-anchored one-pot pyrolysis to obtain Mo single-atom nanozyme (Mo-SAN) with high atomic loading (4.79 wt %) and peroxidase-like activity. The coordination environment and enzyme-like activity mechanism of Mo-SAN were studied by combining synchrotron radiation and density functional theory. The strong oxophilicity of single-atom Mo makes the catalytic center more capable of transferring electrons to free radicals to selectively generate •OH in the presence of H2O2. Choline oxidase and Mo-SAN were used as signal opening unit and signal amplification unit, respectively. Combining the portability and visualization functions of smartphone and test strips, a paper-based visual sensing platform was constructed, which can accurately identify choline at a concentration of 0.5-35 μM with a limit of detection as low as 0.12 μM. The recovery of human serum samples was 96.4-102.2%, with an error of less than 5%. Furthermore, the potential of Mo-SAN to efficiently generate toxic •OH in tumor cells was intuitively confirmed. This work provides a technical and theoretical basis for designing highly active SANs and detecting neurological markers.

Abstract
Solar-driven CO2 reduction by water with a Z-scheme heterojunction affords an avenue to access energy storage and to alleviate greenhouse gas (GHG) emissions, yet the separation of charge carriers and the integrative regulation of water oxidation and CO2 activation sites remain challenging. Here, a BiVO4 /g-C3 N4 (BVO/CN) Z-scheme heterojunction as such a prototype is constructed by spatially separated dual sites with CoOx clusters and imidazolium ionic liquids (IL) toward CO2 photoreduction. The optimized CoOx -BVO/CN-IL delivers an ≈80-fold CO production rate without H2 evolution compared with urea-C3 N4 counterpart, together with nearly stoichiometric O2 gas produced. Experimental results and DFT calculations unveil the cascade Z-scheme charge transfer and subsequently the prominent redox co-catalysis by CoOx and IL for holes-H2 O oxidation and electrons-CO2 reduction, respectively. Moreover, in situ µs-transient absorption spectra clearly show the function of each cocatalyst and quantitatively reveal that the resulting CoOx -BVO/CN-IL reaches up to the electron transfer efficiency of 36.4% for CO2 reduction, far beyond those for BVO/CN (4.0%) and urea-CN (0.8%), underlining an exceptional synergy of dual reaction sites engineering. This work provides deep insights and guidelines for the rational design of highly efficient Z-scheme heterojunctions with precise redox catalytic sites toward solar fuel production.

Abstract
Photocatalytic CO2 conversion promises an ideal route to store solar energy into chemical bonds. However, sluggish electron kinetics and unfavorable product selectivity remain unresolved challenges. Here, an ionic liquid, 1-ethyl-3-methylimidazolium tetrafluoroborate, and borate-anchored Co single atoms were separately loaded on ultrathin g-C3N4 nanosheets. The optimized nanocomposite photocatalyst produces CO and CH4 from CO2 and water under UV-vis light irradiation, exhibiting a 42-fold photoactivity enhancement compared with g-C3N4 and nearly 100% selectivity towards CO2 reduction. Experimental and theoretical results reveal that the ionic liquid extracts electrons and facilitates CO2 reduction, whereas Co single atoms trap holes and catalyze water oxidation. More importantly, the maximum electron transfer efficiency for CO2 photoreduction, as measured with in-situ μs-transient absorption spectroscopy, is found to be 35.3%, owing to the combined effect of the ionic liquid and Co single atoms. This work offers a feasible strategy for efficiently converting CO2 to valuable chemicals.

Abstract
Since traditional fluorescent materials are too easily observed by the eyes just under the UV light, off-on fluorescent materials are explored as the new generation of fluorescent labels. In the "off" state, such off-on fluorescent labels cannot be observed by naked eyes under either natural light or UV light. Only after a specific decryption treatment to make the fluorescent materials turning into the "on" state, the fluorescent labels can be observed under the UV light. Up to now, it is still a challenge to prepare fluorescent inks with aforementioned ideal properties by using halide perovskite materials. Herein, we reported the first example of Te4+ doped indium halide perovskite inks with both off-on fluorescence under solvent stimuli and invisible ink color by the naked eyes. The synergistic effect of doping/undoping of Te4+ together with the reversible phase transformation between Cs2InCl5(H2O) and Cs3InCl6 under solvent stimuli is key for the off-on fluorescence of crystals. Under acid solvent, the substitutional doping of Te4+ during the process of phase transformation from Cs3InCl6 to Cs2InCl5(H2O):Te4+ gives rise to "turning-on" orange emission from Te-induced self-trap emission (STE). Under the stimuli of methanol, the dissolution of Te4+ from the crystals destroys the structure of Te4+ in ligand-field and results in "turning-off" Te-induced emission during the process of phase transformation from Cs2InCl5(H2O):Te4+ to Cs3InCl6. On the basis of the Te4+ doped indium halide perovskite, printable and colorless ink can be prepared for the confidential information encryption and decryption. Since the mixture of Cs3InCl6 crystals and TeCl4 have no absorption in visible light scope, the printed encrypted information by such off-state fluorescent ink is colorless and invisible by the naked eyes under either ambient light or UV light. After decryption by acid solvent stimuli, the resulted Cs2InCl5(H2O):Te4+ doping crystals have a large Stokes shift with absorption below 450 nm from the excitation of Te4+ in ligand-field and emission around 570 nm from Te-induced STE. It makes the decryption information still colorless and invisible by the naked eyes under the ambient light but visible and readable under the UV light. In comparison to traditional undoped CsPbBr3/CsPb2Br5 perovskites with small Stokes shift and eye-visible ink color, the current colorless Te4+doped indium halide perovskites are no doubt providing better security level for both encrypted and decrypted information.

Abstract
BACKGROUND Chronic obstructive pulmonary disease (COPD) is a complex disease characterized by limited airflow and is influenced by genetic and environmental factors. The purpose of this study was to investigate the effects of gene polymorphisms in MIR5708 and MIR1208 on COPD risk. METHODS Four single nucleotide polymorphisms (SNPs) in MIR5708 (rs6473227 and rs16907751) and MIR1208 (rs2608029 and rs13280095) were selected and genotyped among 315 COPD patients and 314 healthy controls using the Agena MassARRAY platform. SPSS 18.0 was used for statistical analysis and data processing. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated to assess the association between genetic variants of MIR1208 and MIR5708 and COPD risk. RESULTS The results suggested that rs16907751 variants in MIR5708 contributed to an increased susceptibility to COPD in the allelic (P = 0.001), co-dominant (homozygous) (P = 0.001), dominant (P = 0.017), recessive (P = 0.002), and additive (P = 0.002) models. The effects of MIR5708 and MIR1208 gene polymorphisms on the risk of COPD were age-, sex-, smoking status-, and BMI-related. Furthermore, the C-A and G-A haplotypes of rs2608029 and rs13280095 in MIR1208 were identified as risk factors for COPD in the population over 70 years (P = 0.029) and in women (P = 0.049), respectively. Finally, significant associations between rs16907751genotypes with pulse rate and forced expiratory volume in 1 s were found among COPD patients. CONCLUSION Genetic polymorphisms in MIR5708 and MIR1208 are associated with increased risk of COPD in China.

Abstract
The ^{13}C(α,n)^{16}O reaction is the main neutron source for the slow-neutron-capture process in asymptotic giant branch stars and for the intermediate process. Direct measurements at astrophysical energies in above-ground laboratories are hindered by the extremely small cross sections and vast cosmic-ray-induced background. We performed the first consistent direct measurement in the range of E_{c.m.}=0.24 to 1.9 MeV using the accelerators at the China Jinping Underground Laboratory and Sichuan University. Our measurement covers almost the entire intermediate process Gamow window in which the large uncertainty of the previous experiments has been reduced from 60% down to 15%, eliminates the large systematic uncertainty in the extrapolation arising from the inconsistency of existing datasets, and provides a more reliable reaction rate for the studies of the slow-neutron-capture and intermediate processes along with the first direct determination of the alpha strength for the near-threshold state.

Abstract
Esophageal cancer-related gene 4 (ECRG4) plays key roles in various malignancies, including lung cancer, prostate cancer, esophageal cancer, and breast cancer, and has potential applications in the early diagnosis, prevention, treatment, and prognosis of cancer. However, the mechanisms underlying the role of ECRG4 in cancer remain elusive. An association between ECRG4 and proliferation, migration, cell cycle, apoptosis, methylation, and ubiquitination in cancer has been found. Additionally, some studies have investigated the regulatory mechanism of the relationship between ECRG4 and long non-coding RNAs, co-factors, and resistance to chemotherapy. Drugs that demethylate ECRG4 are in clinical use. Thus, further investigation of the mechanisms by which ECRG4 influences tumorigenesis, and its clinical significance, are needed. The present study outlines the current understanding of the functions of ECRG4 in cancer and discusses its potential value in cancer therapy.

Abstract
Organic solid-state luminescent materials exhibit numerous exciting photoelectric properties that are central to emergent organic light-emitting diodes, smart sensors, and data encryption. However, the luminescence of pure organic rotor-free materials has been afflicted with strong intermolecular π-π stacking interactions. Herein, an unprecedented pressure-induced emission enhancement (PIEE) is realized in a system of rigid planar pure polycyclic aromatics, i.e., truxene crystals. The emission intensity is enhanced 7-fold below 3.0 GPa with a photoluminescence quantum yield increased to 10.17% compared with the initial value of 1.78%, and the emission colors change from green (520 nm) to red (640 nm) within 11.8 GPa. Spectral characterizations and first-principles calculations reveal that the PIEE and piezochromism can mainly be attributed to the restricted intermolecular vibration and the decreased energy gap. Our findings enrich the PIEE mechanism and provide a new guideline for designing pressure-responsive luminescent materials in advancing their photoelectric applications.

Abstract
Abstract
Background
People with HIV are at increased risk of HPV-disease progression, given the persistence of immune activation and residual inflammation despite effective cART. Whether a low CD4:CD8 T-cell ratio, known to mirror peripheral immune dysfunction, associates with Squamous Intraepithelial Lesions (SIL) is unknown.
Methods
Retrospective cohort study on cART-treated HIV-positive subjects undergoing screening for HPV-related dysplasia (anal/cervical cytology and HPV genotyping). SIL was defined as the presence of either atypical squamous cells of undetermined significance (ASCUS), Low-grade SIL or High-grade SIL. Demographic and viro-immunological parameters (T-cell count, CD4:CD8 T-cell ratio, CD8+CD38+ T-cells percentage) at the time of screening were analyzed by Chi square, Mann Whitney test and multivariate logistic regression analysis.
Results
419 cART-treated subjects were included. Half of the patients had cervical/anal SIL. Individuals with SIL were more commonly males, MSM, co-infected with Treponema pallidum, treated with Integrase Inhibitors (INSTI)-based cART regimens and with a shorter time since HIV diagnosis and cART initiation than subjects with normal cytology. CD38+CD8+ T-cells percentage, but not the CD4:CD8 T-cell ratio, correlated with SIL. HPV infection, especially with multiple and high-risk genotypes, was confirmed associated with SIL. In multivariate analysis, the only factors independently associated with cervical/anal dysplasia were HPV infection and harbouring higher percentages of peripheral activated CD38+CD8+ T-cells.
Conclusions
HPV infection is the major driver of dysplasia in the setting of HIV infection. CD8+CD38+ T-cells also resulted an independent predictor of dysplasia in cART-treated subjects, while the CD4:CD8 T-cell ratio did not. In the setting of HIV-HPV co-infection, the CD4:CD8 T-cell ratio may not fully capture the alterations of HPV-specific immunity.

Abstract
Ferroptosis, resulting from the catastrophic accumulation of lipid reactive oxygen species (ROS) and the inactivation of glutathione (GSH)-dependent peroxidase 4 (GPX4), has emerged as a form of regulated cell death for cancer therapy. Despite progress made with current ferroptosis inducers, efficient systems to trigger ferroptosis remain challenging, owing largely to their low activity, uncontrollable behavior, and even nonselective interactions. Here, we report a self-adaptive ferroptosis platform by engineering a DNA modulator onto the surface of single-atom nanozymes (SAzymes). The modulator could not only specifically intensify the ROS-generating activity but also endow the SAzymes with on-demand GSH-consuming ability in tumor cells, accelerating selective and safe ferroptosis. The self-adaptive antitumor response has been demonstrated in colon cancer and breast cancer, promoting the development of selective cancer therapy.

Abstract
Objective: To analyze the effects of different types of sodium-glucose cotransporter 2 inhibitors (SGLT2i) on 24-hour ambulatory blood pressure in patients with type 2 diabetes mellitus and hypertension. Method: In this meta-analysis, we searched for randomized controlled trials on the effect of SGLT2i on 24-hour ambulatory blood pressure in patients with type 2 diabetes and hypertension. Three databases, namely PubMed, Web of Science and Cochrane Library, were searched. The search was organized on the concept of 3 conceptual groups: the first group contained terms used to describe SGLT2i, the second group contained terms related to blood pressure, and the third group contained terms used to describe randomized controlled trials. The search time was from the establishment of the database to December 2020. The inclusion and exclusion criteria were formulated in accordance with the requirements of the Cochrane systematic review. According to whether the heterogeneity of the study was significant or not, a random effect model or a fixed effect model were used to conduct the analysis on the impact of different types of SGLT2i on 24-hour ambulatory blood pressure and day and night blood pressure in patients with type 2 diabetes and hypertension. Further subgroup analysis was performed to define potential factors, which might lead to clinical heterogeneity. Results: Seven clinical trials were finally included. The result of the meta-analysis showed that compared with placebo group, SGLT2i could reduce the 24-hour dynamic systolic blood pressure of patients with type 2 diabetes and hypertension by 4.36 mmHg (1 mmHg=0.133 kPa). Reduction was 4.59, 3.74, 5.06, and 3.64 mmHg by canagliflozin, dapagliflozin, empagliflozin, and ertugliflozin respectively; SGLT2i could reduce the 24-hour dynamic diastolic blood pressure of patients with type 2 diabetes and hypertension by 2.20 mmHg, and the reduction was 2.30, 1.22, 2.00, and 2.69 mmHg by canagliflozin, dapagliflozin, empagliflozin and ertugliflozin respectively. SGLT2i could reduce the daytime systolic blood pressure of patients with type 2 diabetes and hypertension by 5.25 mmHg, and reduction was 5.38, 4.87, 6.00, and 4.37 mmHg by canagliflozin, dapagliflozin, empagliflozin and ertugliflozin, respectively. Simultaneously, SGLT2i could reduce the diastolic blood pressure of patients with type 2 diabetes and hypertension by 2.62 mmHg, and the reduction was 2.56, 2.47, and 2.80 mmHg by canagliflozin, empagliflozin and ertugliflozin, respectively. SGLT2i could reduce the nighttime systolic blood pressure of patients with type 2 diabetes and hypertension by 3.62 mmHg, and the reduction was 2.09, 2.06, 3.92, and 2.45 mmHg by canagliflozin, dapagliflozin, empagliflozin and ertugliflozin, respectively. At the same time, SGLT2i could reduce the nighttime diastolic blood pressure of patients with type 2 diabetes and hypertension by 1.60 and 1.51 mmHg, the reduction was 1.53 and 2.58 mmHg by canagliflozin, empagliflozin and ertugliflozin, respectively. Conclusion: SGLT2i can reduce 24-hour ambulatory blood pressure in patients with type 2 diabetes and hypertension.

Abstract
A universal strategy is developed to construct a cascade Z‐Scheme system, in which an effective energy platform is the core to direct charge transfer and separation, blocking the unexpected type‐II charge transfer pathway. The dimension‐matched (001)TiO2‐g‐C3N4/BiVO4 nanosheet heterojunction (T‐CN/BVNS) is the first such model. The optimized cascade Z‐Scheme exhibits ≈19‐fold photoactivity improvement for CO2 reduction to CO in the absence of cocatalysts and costly sacrificial agents under visible‐light irradiation, compared with BVNS, which is also superior to other reported Z‐Scheme systems even with noble metals as mediators. The experimental results and DFT calculations based on van der Waals structural models on the ultrafast timescale reveal that the introduced T as the platform prolongs the lifetimes of spatially separated electrons and holes and does not compromise their reduction and oxidation potentials.

Abstract
The radiative and non-radiative decay processes of five compounds are investigated through a comprehensive computational approach, for the aim of investigating the effect of different halogen substituents to the phosphorescent emission. Their optimal configurations at the ground (S0) and lowest triplet excited (T1) states are obtained and the calculated phosphorescent emission spectra are comparable with the experimental values. For 1,4-di(9H-carbazol-9-yl)benzene (PDCz), the electronic transition is between the highest occupied molecular orbital (HOMO) and the lowest unoccupied molecular orbital (LUMO), while for the four halides, the electronic transitions are attributed to several molecular orbitals. According to calculations, 9,9'-(2,5-diiodo-1,4-phenylene)bis(9H-carbazole) (PDICz) possesses the largest radiative decay rate constant (kr) and non-radiative decay rate constant (knr), which can be attributed to the strong spin-orbital coupling from the heavy iodine atom. However, the phosphorescent quantum efficiency (Φ) of PDICz is lower than that of 9,9'-(2,5-dibromo-1,4-phenylene)bis(9H-carbazole) (PDBCz), implying that a comprehensive consideration is necessary. Furthermore, by analyzing the vibrational mode, we have confirmed that the reorganization energies are also influenced by the different halogen atoms. While the dominated factor that determines the kr and knr comes from the spin-orbital coupling. We expect that our research findings will be beneficial to the newly designed organic phosphorescent materials in the future.

Abstract
STUDY QUESTION What is the current status of assisted reproductive technology (ART) service availability, efficacy and safety in mainland China? SUMMARY ANSWER In this first national report on ART status in mainland China, data on treatment numbers, outcomes and complications in 2016 are provided and analyzed, respectively. WHAT IS KNOWN ALREADY National ART Service Provision Surveys are conducted in mainland China regularly. Data were analyzed, and this manuscript was written by team members from the National Center for Women and Children's Health, China CDC and the Department of Women and Children Health, National Health Commission of the People's Republic of China. STUDY DESIGN, SIZE AND DURATION A cross-sectional nationwide survey was completed in 2018, in which data regarding ART treatments, performed from 1st January to 31st December2016 in 445 ART clinics located in 31 provinces of mainland China, were collected. PARTICIPANTS/MATERIALS, SETTING AND METHODS There were in total 451 licensed ART clinics (including artificial insemination clinics) in mainland China in 2016, of which 445 submitted service data. A total of 906 840 cycles were provided by 323 in vitro fertilization (IVF) clinics, involving 375 770 conventional IVF cycles, 154 948 intracytoplasmic sperm injection (ICSI) cycles, 367 146 frozen embryo transfer (FET) thawing cycles and 8976 preimplantation genetic diagnosis (PGD) treatment cycles. A total of 161 376 artificial (i.e. intrauterine) insemination (AI) cycles were reported by 443 clinics, with 126 872 cycles using the husband's semen (AIH) and 34 504 using donor semen (AID). MAIN RESULTS AND THE ROLE OF CHANCE In total, 98.7% of the licensed clinics, contributing to 100% of the ART services (including AID and AIH cycles), were included in this report. (Six clinics provided institutional information only and were excluded.) There were 906 840 in vitro fertilization cycles performed in mainland China with a population of over 1.3 billion inhabitants, with cycles per million inhabitants (C/M) increasing from 360 in 2013 to 657 in 2016, nationwide (range among provinces: 45-3676). After treatment with conventional IVF, the clinical pregnancy rate (PR) per oocyte retrieval cycle was 23.2%, the delivery rate (DR) per oocyte retrieval cycle was 18.7% and the proportion of twin delivery among the total deliveries was 27.9%. For ICSI cycles, the PR, DR and TDR were 20.5%, 16.7% and 27.2%, respectively. For FET per thawing cycles, the PR, DR and TDR were 48.2%, 37.6% and 24.2%. For PGD per diagnosis cycles, the PR, DR and TDR were 38.1%, 29.7% and 4.2%. For AIH cycles, the PR and DR were 13.3% and 10.5%; for AID cycles, the PR and DR were 24.3% and 21.1%, respectively. The total number of live infants born in mainland China in 2016, was 18.46 million, and the number of infants born through ART conducted in 2016 was 311 309, which accounted for 1.69% of the total. The reported rate of birth defects was about 87/10 000. The incidence of moderate to severe ovarian hyper-stimulation syndrome (OHSS) was 11.5 per 1000 oocyte retrieval cycles, and other complications were much more rare. LIMITATIONS AND REASONS FOR CAUTION This report is based on the summary data of ART services provided. The success rates were not calculated by age stratification. A low rate of birth defects was reported, which might be confounded by variations in birth follow-up methods, statistical timing and record taking. WIDER IMPLICATIONS OF THE FINDINGS ART service availability has improved significantly in recent years in mainland China. Because China is a vast country, significant imbalances in ART service provision do exist; however, the main efficacy and safety indicators were close to those of western countries. TRIAL REGISTRATION NUMBER N/A. STUDY FUNDING/COMPETING INTEREST(S) The study was funded by the National Key R&D Program of China (2016YFC1000307-2). There are no competing interests.

Abstract
OBJECTIVES To evaluate the safety and efficacy of chidamide to reverse HIV-1 latency in vivo and to compare the effects of four clinically tested histone deacetylase (HDAC) inhibitors on non-histone proteins in vitro. METHODS Participants received chidamide orally at 10 mg twice weekly for 4 weeks while maintaining baseline antiretroviral therapy. The primary outcome was plasma viral rebound during chidamide dosing and the secondary outcomes were safety, pharmacokinetic and pharmacodynamic profiles, changes in cell-associated HIV-1 RNA and HIV-1 DNA, and immune parameters. Western blotting was used to compare the in vitro effects of the four HDAC inhibitors on HSP90, NF-κB and AP-1. RESULTS Seven aviraemic participants completed eight oral doses of chidamide, and only grade 1 adverse events were observed. Cyclic increases in histone acetylation were also detected. All participants showed robust and repeated plasma viral rebound (peak viraemia 147-3850 copies/mL), as well as increased cell-associated HIV-1 RNA, during chidamide treatment. Furthermore, we identified an enhanced HIV-1-specific cellular immune response and a modest 37.7% (95% CI: 12.7-62.8%, P = 0.028) reduction in cell-associated HIV-1 DNA. Compared with the other three HDAC inhibitors, chidamide had minimal cytotoxicity in vitro at clinically relevant concentrations and showed mechanistically superior effects on non-histone proteins, including HSP90, NF-κB and AP-1. CONCLUSIONS Chidamide safely and vigorously disrupts HIV-1 latency in vivo, which makes it a promising latency-reversing agent.

Abstract
Objective: To evaluate the safety and efficacy of islet transplantation for patients with advanced diabetes. Methods: Five cases of islet allotransplantation were performed on 4 adult recipients. The same blood type adult brain-dead pancreas donors were selected and the islets were prepared in GMP laboratory. The prepared islet suspension was slowly injected into the liver of the recipients within 30-60 minutes. The immunosuppressive regimen was a combination of basiliximab, tacrolimus and mycophenolate mofetil and TNF-alpha monoclonal antibody was used to reduce the post-transplant inflammatory response. Insulin was temporarily applied to control blood glucose after surgery, and the dosage of insulin was adjusted to decrease according to the blood glucose level until it was discontinued. Results: A total of 5 islet transplants were performed in 4 patients, including 1 patient who received the second islet transplantations. All operations were succeed and the blood glucose and portal pressure were stable during the operation. Exogenous insulin was continued to keep blood glucose level stable (4-12 mmol/L) after surgery. Four cases (including the one who received two islet transplantation) started to stop using insulin at the third to fourth week, and the insulin dosage of the other case was 74% lower than that before the operation, and no hypoglycemic reaction occurred in all patients after islet transplantation. The C-peptide level in 3 patients reached the normal range, and the level in one patient with type I diabetes (without insulin release) remained at 0.45-0.6 μg/L (0.15-0.2 nmol/L). In addition, one patient showed a rise in blood glucose again and continued to use insulin half a year after insulin discontinuation. Then, he was performed the second islet transplantation which showed good effect and stopped taking insulin in 10 days after surgery. There were 3 cases of liver puncture bleeding after opeation, of which 2 cases were treated with ultrasound radiofrequency ablation to stop bleeding, 1 case stopped spontaneously, and no other complications were found. Conclusions: Islet transplantation is effective in the treatment of advanced diabetes patients with small trauma and high safety, which is worthy of more promotion. Long-term efficacy and maintenance therapy still need further investigation.

Abstract
The evaluation of female fertility at first diagnosis is an important premise and basis for determining the treatment scheme of assisted reproduction. In this study, a survey was conducted among 13 assisted reproductive institutions in China to understand the evaluation indicators and detection methods of female fertility at first diagnosis in various institutions, and provide a basis for reasonable selection of indicators. The survey showed that the indicators of female fertility evaluation at first diagnosis among assisted reproductive institutions included general health indicators, ovarian reserve indicators, and uterine conditions, etc. The selection of indicators was considerably consistent, but the detection methods were quite different. Therefore, it is necessary to choose the detection method with better validity and less harm.

Abstract
Objective: To study the safety of topical berberine solution in rabbit eyes and its effect on corneal epithelial repair in rabbit eyes. Methods: Experimental Study. Ninety-two Japanese rabbits were randomly divided into two groups by random number table method: the general group (32 rabbits, 64 eyes) and the corneal injury group (60 rabbits, 60 eyes).The general groups were further divided into 4 groups by random number table method, and each group has 8 rabbits (16 eyes). According to the administration of deionized water or 0.5, 1.0, 1.5 mg/ml berberine solution, they were divided into the general control group and the general A, B, and C group. Dosing with both eyes, each eye was given a single dose, and then it was given multiple times for 4 weeks after observation for 72h. After the corneal epithelium injury model made in the right eye of rabbits in the corneal injury groups, they were divided into a corneal injury control group and a corneal injury group A, B, and C according to the administration of deionized water or 0.5, 1.0, 1.5 mg/ml berberine solution. there were 5 rabbits (15 eyes) in each group, and the solutions were given continuously for 1 week. The rabbits in the general group were observed their behavioral changes, ocular surface and iris were scored by Draize eye irritation test scoring system. IOP was measured at different time points. Electroretinogram (ERG) was used to detect b-wave amplitude. In the corneal injury group, corneal epithelial defect repairment was observed at 1, 2, 3, 4, 5, 6, and 7 days after the corneal defect. Corneal histopathology observation after discontinuation of all rabbits. The pH value of rabbit tears was described by the paired t test, and the score of Draize eye irritation test were described by the rank-sum test. The analysis of variance and SNK-q were used for IOP, electroretinogram b-wave amplitude, corneal epithelial injury area and repair time. Results: No abnormal behavior was observed in the general group rabbits after single and multiple administration. There was no significant difference in the Draize eye irritation score among the general control group and the general group A, B, C at 1, 2, and 4 weeks of multiple administrations. Among them, the Draize eye irritation score of the general group C was 7 (0, 12), 6 (0, 10), 6 (0, 16) points (χ(2)=1.640, 0.265, 1.963, 1.381; P>0.05).There were no significant difference in IOP at different times among the general control group and the general group A, B, C at different times (F=0.065, 0.292, 0.015, 0.041; P>0.05). Before multiple administrations and after administration at 2, 4 weeks, the b-wave amplitudes of the general control group were (127.75±17.12), (129.18±15.83), (128.81±13.58) μV, and the general group A were (130.68).±18.75), (131.38±16.96), (130.62±12.18) μV,and the general group B were (128.00±16.74), (128.44±16.64), (129.06±16.16) μV, and the general group C were (131.81±19.37), (132.13±18.36), (129.94±12.60) μV. There was no statistically significant difference in b-wave amplitude in the groups at different times before and after administration (F=0.037, 0.011, 0.017, 0.702; P>0.05). There was no significant difference in the results of corneal histopathology among the general control group and the general group A, B, C. The area of corneal epithelial defect in each corneal injury group was statistically significant at different time (F=5.316, 25.864, 127.613; P<0.05). The corneal injury control group compared with the corneal injury group A, B, C, the corneal epithelial defect area in the corneal injury group C was significantly larger than the other three groups, with statistical differences (q=5.153, 10.313, 6.976; P<0.05). The repair time of corneal epithelial in control group and the group A,B,C of corneal injury were (83.0±1.85), (82.9±2.07), (83.7±2.09) and (101.6±2.20) h. The corneal epithelium defect repair time in group C was longer and the difference was statistically significant (F=301.437, P=0.000). Comparing the corneal injury control group and corneal injury group A and B, there was no statistical difference in the repair time of corneal epithelial defect (F=0.813, P=0.450). After repair, there was no significant difference in the pathological results of the corneal tissue between the corneal injury groups. Conclusions: Berberine solution in rabbit eyes with topical application was safety, and has no obvious toxic effect on the ocular surface and ERG of normal rabbits. 1.5 mg/ml berberine solution delayed the repair of experimental corneal epithelial defect, but had no effect on the integrity of corneal tissue after repair.

Abstract
Objective: To summarize clinical experience on the clinical feature, etiology and treatment of patients with spontaneous bloody tears as the initial symptom. Methods: Retrospective series of case studies. The clinical data and follow-up data of 27 cases of bloody tears as the first symptom in Lacrimal Center of Ophthalmology, the Third Medical Center of Chinese PLA General Hospital from June 2015 to December 2018 were reviewed. The clinical feature, specific cause, diagnosis, treatment and prognosis of these cases were evaluated. Results: A total of 27 cases were collected in this study. The patients were 10 males (37.0%) and 17 females (63.0%), including 21 adults (≥ 18 years old, 77.8%) and 6 minors (<18 years old, 22.2%). There were 22 monocular cases (81.5%) and 5 binocular cases (18.5%). Five cases (18.5%) were bleeding from the eye and other parts of the body, and 22 cases (81.5%) were bleeding only from the eye. There were 19 cases (70.4%) with hematic epiphora and secretions from the punctum, 3 cases (11.1%) with blood-stained tears, and 7 cases (25.9%) with blood-like tears. With regard to etiology, 6 cases (22.2%) were combined with systemic lesions, one of which was granulomatosis with polyangiitis and five of which (<18 years old) were idiopathic bloody tears. Twenty-one cases (77.8%) were local lesions, including 18 cases only involving the lacrimal system, 2 cases only involving the ocular surface, and 1 case involving both the lacrimal system and the ocular surface. Among the 21 cases with local lesions, 5 cases were induced by foreign body, 6 cases were induced by simple inflammation, and 10 cases were induced by tumor including 1 case with conjunctival benign tumor and 9 cases with tumor of the lacrimal system (5 with malignant tumor and 4 with benign tumor). Patients with idiopathic bloody tears received psychological and medical treatment, and interictal discharge was lengthened. One case of granulomatosis with polyangiitis was treated by trans-nasal endoscopic dacryocystorhinostomy. With the recurrence of granulomatosis and polyangiitis, bloody tears recurred after surgery. One patient with conjunctival hemangioma was untreated. Lesions in the lacrimal duct system were removed and dacryocystorhinostomy was performed. In this study, 2 patients (1 with small cell neuroendocrine carcinoma and 1 with adenoid cystic adenocarcinoma) died and the other had a good prognosis. Conclusions: Among the cases of bloody tears, adults and local lesions are more common. Most of the lesions are located in the lacrimal system and are tumors. The main treatment is to remove the lesions, and if necessary, to expand the resection and reconstruct the lacrimal duct. Idiopathic bloody tears occur in minors, who are gave psychotherapy and necessary medical treatment. (Chin J Ophthalmol, 2020, 56: 53-58).

Abstract
A fluorescent probe that responds at distinct wavelengths upon exposure to cyanide, hypochlorite, and bisulfite was synthesized. As a result, an easy to apply analytical methodology was developed for the detection of these ions. The feasibility of this method was evaluated by theoretical calculations. The probe exhibited excellent solubility in the test solution (H2O: DMF = 99: 1, v: v) with low detection limits for cyanide, hypochlorite and bisulfite (4.5 × 10 -8 M, 4.9 × 10 -7 M and 4.3 × 10 -8 M respectively) showing distinct emission wavelengths for each ion without interference in practical application. Furthermore, the probe had low toxicity and was applied for the imaging experiments of cyanide, hypochlorite and bisulfite in living HeLa and MDCK cells.

Abstract
Mycotoxins, such as aflatoxin B1 (AFB1), deoxynivalenol (DON), zearalenone (ZEA) and ochratoxin A (OTA) are toxic secondary compounds that can reduce the quality of many kinds of food and may lead to other ill effects, both in humans and animals. This study aimed to investigate the potential of the ultrasound (US) treatment in the removal of AFB1, DON, ZEA and OTA from aqueous solution and maize by examining degradation rates and influencing factors of ultrasonication, such as the initial concentrations, power intensity, sonication duration, and duty cycle. The results showed that US treatment could simultaneously reduce AFB1, DON, ZEA and OTA effectively in aqueous solution. The degradation of mycotoxins was significantly affected by the ultrasonic intensity (2.2-11 W/cm3) and sonication time range from 10 to 50 min. DON is more stable than AFB1, ZEA, and OTA in the US treatment. It was found that, for the first time to our knowledge, the highest degradation rates of AFB1, DON, ZEA and OTA were attained at a duty cycle of 25%, and they were 96.5, 60.8, 95.9 and 91.6%, respectively. US strategy can be considered as an effective treatment to degrade the mycotoxins in aqueous solutions and food matrix.

Abstract
Abstract
Background
Previous studies have shown that acetylation plays a critical role in regulating the progress of cardiovascular diseases by acetylated histone and non-histones protein. However, the global lysine acetylome during atrial fibrillation (AF) were not fully understood.
Purpose
The aim of the present study was to identify the underlying mechanisms of AF via profiling of the quantitative changes of global proteomics and lysine acetylome in the left atrial appendage (LAA) tissues from valvular heart disease patients with AF.
Methods
This study obtained LAA specimens from patients undergoing cardiac surgery for severe valvular heart disease. The LAA specimens were obtained from both 9 patients with AF and with sinus rhythm (SR). The changes of proteome and acetylome in the AF-LAA vs SR-LAA tissues were studied using dimethyl-labeling, HPLC fractionation, affinity enrichment, LC-MS/MS analysis, database Search and bioinformatic analysis. The acetylated levels of each lysine acetylated site were normalized on the basis of the corresponding protein abundance.
Results
The bioinformatic analysis indicates 294 up-regulated (AF/SR ratio >1.3) proteins and 169 down-regulated (AF/SR ratio <1/1.3) proteins in the AF-LAA vs SR-LAA were detected. Moreover, 3,880 sites in 1,044 proteins were quantified. Motif analysis of the identified acetylated peptides indicated that a total of 14 significantly enriched amino acid sequence motifs from −10 to +10 surrounding the acetylated lysine (Kac) were defined according to 3412 peptides from 1115 proteins. Among the quantified acetylated sites and proteins, 231 up-regulated acetylated sites in 130 proteins and 121 down-regulated acetylated sites in 74 proteins were detected. The enrichment-based clustering analysis showed that energy metabolism and cardiac contraction-related proteins were highly differentially expressed in the AF-LAA vs SR-LAA. Meanwhile, the protein-protein interaction network of the differentially expressed acetylated proteins demonstrated that there were 146 nodes and 569 interactions in the network and quite a lot of interactions in energy metabolism-related proteins and in cardiac contraction-related proteins. Furthermore, the acetylated levels of most differentially expressed energy metabolism-related proteins involving in oxidative phosphorylation, TCA cycle, respiratory ETC, fatty acid metabolism were up-regulated. On the contrary, the acetylated levels of most acetylated sites in differentially expressed cardiac contraction-related proteins including the key contraction proteins were down-regulated.
Interaction network of Ac-proteins
Conclusions
This study details and expands our understanding of the changes of proteome and lysine acetylome in the LAA tissues from valvular heart disease patients with AF. The data suggest important expression differences of acetylated proteins related to energy metabolism and cardiac contraction which may be involved in the matrix of AF formation and maintainence.

Abstract
Cascade charge transfer was realized by a H-bond linked zinc phthalocyanine/BiVO4 nanosheet (ZnPc/BVNS) composite, which subsequently works as an efficient wide-visible-light-driven photocatalyst for converting CO2 into CO and CH4 , as shown by product analysis and 13 C isotopic measurement. The optimized ZnPc/BVNS nanocomposite exhibits a ca. 16-fold enhancement in the quantum efficiency compared with the reported BiVO4 nanoparticles at the excitation of 520 nm with an assistance of 660 nm photons. Experimental and theoretical results show the exceptional activities are attributed to the rapid charge separation by a cascade Z-scheme charge transfer mechanism formed by the dimension-matched ultrathin (ca. 8 nm) heterojunction nanostructure. The central Zn2+ in ZnPc could accept the excited electrons from the ligand and then provide a catalytic function for CO2 reduction. This Z-scheme is also feasible for other MPc, such as FePc and CoPc, together with BVNS.
