Abstract
Background Myocardial infarction (MI) is one of the most lethal cardiovascular diseases. The loss of cardiomyocytes and the degradation of the extracellular matrix leads to high ventricular wall stress, which further drives the pathological thinning of the ventricular wall during MI. Injecting biomaterials to thicken the infarct ventricular wall provides mechanical support, thereby inhibiting the continued expansion of the heart. As an injectable biomaterial, alginate hydrogel has achieved exciting results in clinical trials, but further research needs to be conducted to determine whether it can improve cardiac function in addition to providing mechanical support. This study sought to explore these mechanisms in an animal model of MI. Methods A MI model was established in male C57BL/6J mice by ligation of the proximal left anterior descending (LAD) coronary artery. Intramyocardial injections (hydrogel or saline group) were performed in the proximal wall regions bordering the infarct area (with one 20-µL injection). Four weeks after MI, RNA sequencing revealed that 342 messenger RNAs (mRNAs) from the infarcted hearts were differentially expressed between the saline group and hydrogel group. We subsequently conducted a Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis to analyze the RNA sequencing data. In addition, we employed both western blotting and quantitative reverse transcriptase polymerase chain reaction (qRT-PCR) techniques to verify a number of genes that were differentially expressed and could potentially affect cardiac function after MI. Subsequently, we confirmed these findings through in vitro experiments. Results We found that compared with hydrogel treatment group, 250 mRNAs were upregulated and 92 mRNAs were downregulated in saline group (P<0.05). And by exploring the GO and KEGG signaling pathways as well as the protein-protein interaction (PPI) network, we found that administration of alginate hydrogel modulated cardiomyocyte inflammation-associated proteins as well as chemokine-related proteins during the inflammatory response phase after MI. In addition, our analysis at both the protein and RNA level revealed that B2M was effective in improving cardiac function after MI in the hydrogel treatment group, which was consistent in the myocardium oxygen and glucose deprivation (OGD) injury model. Conclusions We explored the transcriptome changes of infarcted hearts after alginate-hydrogel injection during the inflammatory response period. Our findings suggest that the injectable hydrogel directly alters the inflammatory response and the chemokine-mediated signaling pathway of cardiomyocytes, ultimately improving cardiac function.

Abstract
OBJECTIVE To observe the effect of Shenqi Chongcao (SQCC) Formula on the ASS1/src/STAT3 signaling pathway in a rat model of lung fibrosis and explore its therapeutic mechanism. METHODS A total of 120 male SD rats were divided equally into 5 groups, including a blank control group with saline treatment and 4 groups of rat models of idiopathic pulmonary fibrosis induced by intratracheal instillation of bleomycin. One day after modeling, the rat models were treated with daily gavage of 10 mL/kg saline, SQCC decoction (0.423 g/kg), pirfenidone (10 mL/kg), or intraperitoneal injection of arginine deiminase (ADI; 2.25 mg/kg, every 3 days) for 28 days. After the treatments, the lung tissues of the rats were collected for calculating the lung/body weight ratio, observing histopathology using HE and Masson staining, and analyzing the inflammatory cells in BALF using Giemsa staining. Serum chemokine ligand 2 (CCL2) and transforming growth factor-β1 (TGF-β1) levels were measured with ELISA. The protein expressions of src, p-srcTry529, STAT3, and p-STAT3Try705 and the mRNA expressions of ASS1, src and STAT3 in the lung tissues were detected using Western blotting and RT-qPCR. RESULTS The neutrophil, macrophage and lymphocyte counts and serum levels of CCL2 and TGF-β1 were significantly lower in SQCC, pirfenidone and ADI treatment groups than in the model group at each time point of measurement (P < 0.05). P-srcTry529 and p-STAT3Try705 protein expression levels and ASS1, src, and STAT3 mRNA in the lung tissues were also significantly lower in the 3 treatment groups than in the model group (P < 0.05). CONCLUSION SQCC Formula can alleviate lung fibrosis in rats possibly by activating the ASS1/src/STAT3 signaling pathway in the lung tissues.

Abstract
BACKGROUND As an endemic shrub of the Qinghai-Tibetan Plateau (QTP), the distribution of Hippophae tibetana Schlecht. ranges between 2800 and 5200 m above sea level. As the most basal branch of the Hippophae genus, H. tibetana has an extensive evolutionary history. The H. tibetana is a valuable tree for studying the ecological evolution of species under extreme conditions. RESULTS Here, we generated a high-quality chromosome-level genome of H. tibetana. The total size of the assembly genome is 917 Mb. The phylogenomic analysis of 1064 single-copy genes showed a divergence between 3.4 and 12.8 Mya for H. tibetana. Multiple gene families associated with DNA repair and disease resistance were significantly expanded in H. tibetana. We also identified many genes related to DNA repair with signs of positive selection. These results showed expansion and positive selection likely play important roles in H. tibetana's adaptation to comprehensive extreme environments in the QTP. A comprehensive genomic and transcriptomic analysis identified 49 genes involved in the flavonoid biosynthesis pathway in H. tibetana. We generated transgenic sea buckthorn hairy root producing high levels of flavonoid. CONCLUSIONS Taken together, this H. tibetana high-quality genome provides insights into the plant adaptation mechanisms of plant under extreme environments and lay foundation for the functional genomic research and molecular breeding of H. tibetana.

Abstract
Introduction Actinorhizal symbioses are gaining attention due to the importance of symbiotic nitrogen fixation in sustainable agriculture. Sea buckthorn (Hippophae L.) is an important actinorhizal plant, yet research on the microbial community and nitrogen cycling in its nodules is limited. In addition, the influence of environmental differences on the microbial community of sea buckthorn nodules and whether there is a single nitrogen-fixing actinomycete species in the nodules are still unknown. Methods We investigated the diversity, community composition, network associations and nitrogen cycling pathways of the microbial communities in the root nodule (RN), nodule surface soil (NS), and bulk soil (BS) of Mongolian sea buckthorn distributed under three distinct ecological conditions in northern China using 16S rRNA gene and metagenomic sequencing. Combined with the data of environmental factors, the effects of environmental differences on different sample types were analyzed. Results The results showed that plants exerted a clear selective filtering effect on microbiota, resulting in a significant reduction in microbial community diversity and network complexity from BS to NS to RN. Proteobacteria was the most abundant phylum in the microbiomes of BS and NS. While RN was primarily dominated by Actinobacteria, with Frankia sp. EAN1pec serving as the most dominant species. Correlation analysis indicated that the host determined the microbial community composition in RN, independent of the ecological and geographical environmental changes of the sea buckthorn plantations. Nitrogen cycle pathway analyses showed that RN microbial community primarily functions in nitrogen fixation, and Frankia sp. EAN1pec was a major contributor to nitrogen fixation genes in RN. Discussion This study provides valuable insights into the effects of eco-geographical environment on the microbial communities of sea buckthorn RN. These findings further prove that the nodulation specificity and stability of sea buckthorn root and Frankia sp. EAN1pec may be the result of their long-term co-evolution.

Abstract
PURPOSE Autoimmune Thyroiditis (AIT) is the most common thyroid disease; however, there were no measures to prevent the progression of the disease. The present study attempts to identify that Notch signaling regulates the differentiation of T helper 17 (Th17) cells by activating downstream Phosphatidylinositol-3 kinase/protein kinase/mechanistic target of rapamycin complex 1 (PI3K/AKT/mTORC1) pathway participating in the thyroid injury of the experimental autoimmune thyroiditis (EAT). METHODS In vivo experiments, mice were randomly divided into 4 groups: a control group, an EAT group, and two groups with LY294002 treatment (pTg plus 25 mg/kg or 50 mg/kg LY294002, respectively). The degrees of thyroiditis were evaluated, and the percentage of Th17 cells, expression of interleukin-17A (IL-17A), and the main components of the Notch-PI3K signaling pathway were detected in different groups. In vitro experiments, two different dosages of LY294002 (25 and 50 μM) were used to intervene splenic mononuclear cells (SMCs) from EAT mice to further evaluate the regulatory effect of Notch-PI3K pathway on Th17 cells. RESULTS Our data demonstrate that the infiltration of Th17 cells and the expressions of IL-17A, Notch, hairy and split 1 (Hes1), p‑AKT (Ser473), p‑AKT (Thr308), p‑mTOR (Ser2448), S6K1, and S6K2 increased remarkably in EAT mice. After PI3K pathway was blocked, the degrees of thyroiditis were significantly alleviated, and the proportion of Th17 cells, the expression of IL-17A, and the above Notch-PI3K pathway-related molecules decreased in a dose-dependent manner. Additionally, the proportion of Th17 cells was positively correlated with the concentration of serum thyroglobulin antibody (TgAb), IL-17A, and Notch-PI3K pathway-related molecules mRNA levels. CONCLUSIONS Notch signal promotes the secretion of IL-17A from Th17 cells by regulating the downstream PI3K/AKT/mTORC1 pathway through Hes-Phosphatase and tensin homolog (PTEN) and participates in thyroid autoimmune damage, and the PI3K pathway inhibitor may play important effects on AIT by affecting Th17 cells differentiation.

Abstract
We have used quantum control to suppress the impact of random atom positions on coherent population transfer within atom pairs, enabling the observation of dipole-dipole driven Rabi oscillations in a Rydberg gas with hundreds of atoms. The method exploits the reduced coupling-strength sensitivity of the off-resonant Rabi frequency, and coherently amplifies the achievable population transfer in analogy to quasi-phase-matching in nonlinear optics. Simulations reproduce the experimental results and demonstrate the potential benefits of the technique to other many-body quantum control applications.

Abstract
OBJECTIVE This study aims to evaluate the diagnostic efficiency of diffusion-weighted imaging (DWI) in patients with placenta accreta spectrum (PAS). MATERIALS AND METHODS The present study searched on PubMed, Embase, OVID, Cochrane, Scopus and CNKI, Chinese Bio-Medical Literature, VIP, Wanfang, Duxiu, databases for studies related to the diagnostic performance of DWI for PAS from inception to December 2022. The pooled sensitivity, the pooled specificity, positive likelihood ratio (LR+), negative likelihood ratio (LR-), and diagnosis odds ratios (DOR) were calculated by Meta-disc 1.4 and STATA 16.0. RESULTS A total of 11 studies met the criteria and were included in the meta-analysis. The effect indexes of DWI in combined PAS were as follows. The pooled sensitivity was 0.670 (0.619-0.719). The pooled specificity was 0.720 (0.661-0.773). The pooled LR+ was 2.161 (1.454-3.211). The pooled LR- was 0.413 (0.280-0.609). The pooled AUC was 0.7841, and Q* was 0.7221. The pooled diagnostic ratio DOR was 6.713 (2.981-15.118). Subgroup analysis showed that four studies used T2-weighted imaging (T2WI) + DWI to diagnose PAS, and the pooled AUC was 0.9822. CONCLUSIONS The results showed that DWI had high sensitivity and specificity in the diagnosis of PAS. Furthermore, T2WI+DWI has higher diagnostic efficacy than DWI alone in the diagnosis of PAS. Therefore, it is necessary to set T2WI+DWI as a routine sequence for PAS, and T2WI+DWI should be a routine method for the daily diagnosis of PAS.

Abstract
To study the efficacy and compliance analysis of pollen allergen drops in the treatment of allergic rhinitis. The method of single-center controlled was used to analyze the dates' results. From July 2021 to September 2021, 80 patients with seasonal allergic rhinitis were referred to the clinic of otorhinolaryngology in First Hospital of Shanxi Medical University.40 patients received sublingual immunotherapy (SLIT group), and the other 40 patients received symptomatic drug treatment as the control group. The total rhinoconjunctivitis symptom score (TRSS), the visual analogue scale(VAS), total medication score (TMS) and combined scores of medication and rhinoconjunctivitis symptoms (CSMRS) of the patient before the start of the treatment and after the first year of the treatment were compared to assess the efficacy of sublingual immunotherapy of Artemisia pollen. Follow the shedding during the study, the safety of the drug and the causes for compliance analysis were analyzed and recorded. The results of comparison with TRSS, VAS, TMS and CSMRS in two groups in the period of pretherapy were as follows: TRSS(12.393±3.023, 12.450±3.029, t=-0.077, P=0.939), VAS(8.357±1.026, 8.400±0.982, t=-0.173, P=0.862), TMS(3.214±0.568, 3.175±0.501, t=0.301, P=0.764), CSMRS (5.286±0.680, 5.253±0.677, t=0.199, P=0.843), there was no significant difference (P>0.05); lower observed symptom scores were got in the post-treatment pollen peak SLIT group compared to the control group, TRSS(3.964±1.551, 7.750±2.169, t=-7.918, P<0.05), VAS(2.893±0.956, 5.175±1.481, t=-8.286, P<0.05), TMS (1.821±0.863, 3.175±0.501, t=-8.163, P<0.05), CSMRS (2.489±0.921, 4.468±0.601, t=-10.723, P<0.05), and the differences between the groups were statistically significant (P<0.05); the SLIT group significantly reduced all symptom scores at the first peak compared to the starting, TRSS(12.393±3.023, 3.964±1.551, t=20.576, P<0.05), VAS (8.357±1.026, 2.893±0.956, t=30.070, P<0.05), TMS (3.214±0.568, 1.821±0.863, t=7.151, P<0.05), CSMRS(5.286±0.680, 2.489±0.921, t=14.533, P<0.05) and there was statistical difference (P<0.05). No significant adverse reactions occured during medication in the SLIT group. A total of 12 cases were shed in the SLIT group, so the compliance rate was 70%. The four reasons were that patients considered the course was long (4 cases, 33%); the drugs were expensive (3 cases, 25%); patients were busy with their work and life (3 cases, 25%); patients were affected by the outbreak (2 cases, 17%). In summary, Artemisia pollen sublingual drops may improve the symptoms of the patients who got allergic rhinitis caused by Artemisia pollen after the treatment for one year. However, due to the lack of sufficient understanding of immunotherapy or the difficulty in adhering to standardized medication, the compliance with sublingual immunotherapy is still poor, the compliance with sublingual immunotherapy needs to be further improved through patient education.

Abstract
Erythro-myeloid progenitors of the yolk sac that originates during early embryo development has been suggested to generate tissue-resident macrophage, mast cell, and even endothelial cell populations from fetal to adult stages. However, the heterogeneity of erythro-myeloid progenitors (EMPs) is not well characterized. Here, we adapt single-cell RNA sequencing to dissect the heterogeneity of EMPs and establish several fate-mapping tools for each EMP subset to trace the contributions of different EMP subsets. We identify two primitive and one definitive EMP subsets from the yolk sac. In addition, we find that primitive EMPs are decoupled from definitive EMPs. Furthermore, we confirm that primitive and definitive EMPs give rise to microglia and other tissue-resident macrophages, respectively. In contrast, only Kit+ Csf1r- primitive EMPs generate endothelial cells transiently during early embryo development. Overall, our results delineate the contribution of yolk sac EMPs more clearly based on the single-cell RNA sequencing (scRNA-seq)-guided fate-mapping toolkit.

Abstract
Objective: To explore the clinical characteristics and treatment outcomes of patients with lightning injury on plateau in Tibet Autonomous Region, and to analyze the risk factors for heart injuries in these patients. Methods: A retrospective case series study was conducted. From January 2008 to July 2023, 55 patients with lightning injury who met the inclusion criteria were admitted to the General Hospital of PLA Tibet Military Area Command. The gender, age, ethnicity, time of injury, location of injury (average altitude), activity at the time of injury, the occurrence of thermal burns on the body surface, the occurrence of complication, the occurrence of combined injury, underlying disease or physiological process before injury, length of hospital stay, treatment outcome, and effective rate of treatment were recorded. The patients were divided into juvenile group (11 cases), young group (28 cases), middle-aged group (14 cases), and elderly group (2 cases) according to age bracket, then the gender and ethnicity distribution of patients in the 4 groups were compared. According to the occurrence of heart injuries at admission, the patients were divided into heart injury group (44 cases) and non-heart injury group (11 cases), then the gender, age, ethnicity, average altitude of location of injury, length of hospital stay, the occurrence of complication, the occurrence of combined injury, site of thermal burns on the body surface, and area of thermal burns on the body surface in patients were compared between the two groups. Data were statistically analyzed with Mann-Whitney U test, chi-square test, or Fisher's exact probability test. The multivariate logistic regression analysis was conducted to screen the independent risk factors for heart injury in patients with lightning injury. Results: Among the 55 patients aged 10-68 years, 39 were male and 16 were female, including 47 Tibetans and 8 Hans. There were no statistically significant differences in gender or ethnicity distribution of patients among the 4 groups with different age brackets (P>0.05). Lightning injuries occurred from May to September, which mostly occurred in June and July. The incidence of lightning injury was higher in Chengguan District of Lhasa City (average altitude of 3 650 m) and Baqing County of Naqu City (average altitude of 4 500 m), being 20.0% (11/55) and 16.4% (9/55), respectively. A total of 96.4% (53/55) of the patients were engaged in outdoor activities when injured, such as grazing, digging Cordyceps, and harvesting highland barley. Among the 55 patients, 46 (83.6%) cases had thermal burns on the body surface, with burn area mainly being not more than 10% total body surface area and burn depth mainly being deep partial-thickness. Fifty-two (94.5%) patients had complications, with heart injury being the most common complication (44 cases, 80.0%). Twenty-two (40.0%) patients had 11 combined injuries, and traumatic brain injury was the most common combined injury. Seventeen (30.9%) patients had 11 underlying diseases or physiological processes before injury. The length of hospital stay of patients was 9 (5, 17) d. Among the 55 patients, 14 cases were cured and discharged, 40 cases were improved, and 1 case died, with effective rate of treatment of 98.2%. Compared with those in non-heart injury group, the proportion of complication occurrence (χ2=12.28), the proportion of trunk burns (χ2=5.15), and the average altitude of location of injury (Z=-2.38) of patients in heart injury group were increased significantly (P<0.05), while there were no significant changes in the other indicators (P>0.05). Multivariate logistic regression analysis showed that the average altitude at the location of injury was the independent risk factor for heart injury in patients with lightning injury (with odds ratio of 3.28, 95% confidence interval of 1.35-7.99, P<0.05). Conclusions: Lightning injuries on plateau in Tibet Autonomous Region mainly occur from May to September, with an average altitude of 4 500 m at the location of injury. Patients with lightning injury are injured when participating outdoor activities, and the affected patients are mainly mainly young male Tibetans. Most of the injuries are mild burns. Lightning injuries are complex and have many complications, with heart injury being the most common one. The average altitude at the location of injury is the independent risk factor for heart injury in patients with lightning injury.

Abstract
Objective: To evaluate the value of nasal nitric oxide (nNO) measurement as a diagnostic tool for Chinese patients with primary ciliary dyskinesia (PCD). Methods: This study is a retrospective study. The patients were recruited from those who were admitted to the respiratory Department of Respiratory Medicine, Children's Hospital of Fudan University from March 2018 to September 2022. Children with PCD were included as the PCD group, and children with situs inversus or ambiguus, cystic fibrosis (CF), bronchiectasis, chronic suppurative lung disease and asthma were included as the PCD symptom-similar group. Children who visited the Department of Child health Care and urology in the same hospital from December 2022 to January 2023 were selected as nNO normal control group. nNO was measured during plateau exhalation against resistance in three groups. Mann-Whitney U test was used to analyze the nNO data. The receiver operating characteristic of nNO value for the diagnosis of PCD was plotted and, the area under the curve and Youden index was calculated to find the best cut-off value. Results: nNO was measured in 40 patients with PCD group, 75 PCD symptom-similar group (including 23 cases of situs inversus or ambiguus, 8 cases of CF, 26 cases of bronchiectasis or chronic suppurative lung disease, 18 cases of asthma), and 55 nNO normal controls group. The age of the three groups was respectively 9.7 (6.7,13.4), 9.3 (7.0,13.0) and 9.9 (7.3,13.0) years old. nNO values were significantly lower in children with PCD than in PCD symptom-similar group and nNO normal controls (12 (9,19) vs. 182 (121,222), 209 (165,261) nl/min, U=143.00, 2.00, both P<0.001). In the PCD symptom-similar group, situs inversus or ambiguus, CF, bronchiectasis or chronic suppurative lung disease and asthma were significantly higher than children with PCD (185 (123,218), 97 (52, 132), 154 (31, 202), 266 (202,414) vs. 12 (9,19) nl/min,U=1.00, 9.00, 133.00, 0, all P<0.001). A cut-off value of 84 nl/min could provide the best sensitivity (0.98) and specificity (0.92) with an area under the curve of 0.97 (95%CI 0.95-1.00, P<0.001). Conclusions: nNO value can draw a distinction between patients with PCD and others. A cut-off value of 84 nl/min is recommended for children with PCD.

Abstract
INTRODUCTION We performed a meta-analysis to evaluate the effect of en-bloc transurethral resection vs. conventional transurethral resection for primary non-muscle invasive bladder cancer. METHODS A systematic literature search up to January 2022 was done and 28 studies included 3714 primary non-muscle invasive bladder cancer subjects at the start of the study; 1870 of them were en-bloc transurethral resection, and 1844 were conventional transurethral resection for primary non-muscle invasive bladder cancer. We calculated the odds-ratio (OR) and mean-difference (MD) with 95% confidence-intervals (CIs) to evaluate the effect of en-bloc transurethral resection compared with conventional transurethral resection for primary non-muscle invasive bladder cancer by the dichotomous or continuous methods with random or fixed-effects models. RESULTS En-bloc transurethral resection had significantly lower twenty-four-month recurrence (OR: 0.63; 95%CI: 0.50-0.78; p < 0.001), catheterization-time (MD: -0.66; 95%CI: -1.02-[-0.29]; p < 0.001), length of hospital stay (MD: -0.95; 95%CI: -1.55-[-0.34]; p = 0.002), postoperative bladder irrigation duration (MD: -6.06; 95%CI: -9.45-[-2.67]; p < 0.001), obturator nerve reflex (OR: 0.08; 95%CI: 0.02-0.34; p = 0.03), and bladder perforation (OR: 0.14; 95%CI: 0.06-0.36: p < 0.001) and no significant difference in the 12-month-recurrence (OR: 0.79; 95%CI: 0.61-1.04; p = 0.09), the operation time (MD: 0.67; 95%CI: -1.92 to 3.25; p = 0.61), and urethral stricture (OR: 0.46; 95%CI: 0.14-1.47; p = 0.0.19) compared with conventional transurethral resection for primary non-muscle invasive bladder cancer subjects. CONCLUSIONS En-bloc transurethral resection had a significantly lower twenty-four-month recurrence, catheterization time, length of hospital stay, postoperative bladder irrigation duration, obturator nerve reflex, bladder perforation, and no significant difference in the twelve-month recurrence, operation time, and urethral stricture compared with conventional transurethral resection for primary non-muscle invasive bladder cancer subjects. Further studies are required.

Abstract
OBJECTIVE To explore the regulatory mechanism of human hepatocyte apoptosis induced by lysosomal membrane protein Sidt2 knockout. METHODS The Sidt2 knockout (Sidt2-/-) cell model was constructed in human hepatocyte HL7702 cells using Crispr-Cas9 technology.The protein levels of Sidt2 and key autophagy proteins LC3-II/I and P62 in the cell model were detected using Western blotting, and the formation of autophagosomes was observed with MDC staining.EdU incorporation assay and flow cytometry were performed to observe the effect of Sidt2 knockout on cell proliferation and apoptosis.The effect of chloroquine at the saturating concentration on autophagic flux, proliferation and apoptosis of Sidt2 knockout cells were observed. RESULTS Sidt2-/- HL7702 cells were successfully constructed.Sidt2 knockout significantly inhibited the proliferation and increased apoptosis of the cells, causing also increased protein expressions of LC3-II/I and P62(P < 0.05) and increased number of autophagosomes.Autophagy of the cells reached a saturated state following treatment with 50 μmol/L chloroquine, and at this concentration, chloroquine significantly increased the expressions of LC3B and P62 in Sidt2-/- HL7702 cells. CONCLUSION Sidt2 gene knockout causes dysregulation of the autophagy pathway and induces apoptosis of HL7702 cells, and the latter effect is not mediated by inhibiting the autophagy-lysosomal pathway.

Abstract
Objective To evaluate the effects of two genetic variants in the promoter of the miR-143/145 cluster on the risk of epithelial ovarian cancer (EOC) and the prognosis of EOC patients. Study design Genotypes were determined by the polymerase chain reaction and ligase detection reaction method in 563 EOC patients and 576 healthy women. The expression of miR-143 and miR-145 were detected by quantitative real-time polymerase chain reaction (qRT-PCR) in fifty-two EOC tissues. Results The rs4705342 CC genotype frequencies in EOC patients were higher than those in the controls (P = 0.014). Furthermore, the CC genotype of rs4705342 was associated with an advanced FIGO stage of EOC patients (P = 0.046). Patients with the rs4705342 CC genotype had shorter progression-free survival (PFS) and overall survival (OS) times than those carrying the TT genotype in multivariable analysis adjusting for clinical variables (HR = 1.30, 95% CI = 1.04-1.62, P = 0.020; HR = 1.33, 95% CI = 1.05-1.70, P = 0.020). In addition, the miR-145 levels were lower in EOC tissues with the rs4705342 CC genotype than in those with the TT genotype (P = 0.005). Conclusion The CC genotype of rs4705342 was related to an increased risk of EOC and poor prognosis of EOC patients, and rs4705342 may serve as a molecular marker for predicting the development of EOC and the clinical outcome of EOC patients.

Abstract
BACKGROUND Mycobacterium abscessus (MABS) group are environmental organisms that can cause infection in people with cystic fibrosis (CF) and other suppurative lung diseases. There is potential for person-to-person airborne transmission of MABS among people with CF attending the same care centre. Ultraviolet light (band C, UV-C) is used for Mycobacterium tuberculosis control indoors; however, no studies have assessed UV-C for airborne MABS. AIM To determine whether a range of UV-C doses increased the inactivation of airborne MABS, compared with no-UVC conditions. METHODS MABS was generated by a vibrating mesh nebulizer located within a 400 L rotating drum sampler, and then exposed to an array of 265 nm UV-C light-emitting diodes (LED). A six-stage Andersen Cascade Impactor was used to collect aerosols. Standard microbiological protocols were used for enumerating MABS, and these quantified the effectiveness of UV-C doses (in triplicate). UV-C effectiveness was estimated using the difference between inactivation with and without UV-C. FINDINGS Sixteen tests were performed, with UV-C doses ranging from 276 to 1104 μW s/cm2. Mean (±SD) UV-C effectiveness ranged from 47.1% (±13.4) to 83.6% (±3.3). UV-C led to significantly greater inactivation of MABS (all P-values ≤0.045) than natural decay at all doses assessed. Using an indoor model of the hospital environment, it was estimated that UV-C doses in the range studied here could be safely delivered in clinical settings where patients and staff are present. CONCLUSION This study provides empirical in-vitro evidence that nebulized MABS are susceptible to UV-C inactivation.

Abstract
BACKGROUND Reliable noninvasive methods are needed to identify endotypes of chronic rhinosinusitis with nasal polyps (CRSwNP) to facilitate personalized therapy. Previous computed tomography (CT) scoring system has limited and inconsistent performance in identifying eosinophilic CRSwNP. We aimed to develop and validate a radiomics-based model to identify eosinophilic CRSwNP. METHODS Surgical patients with CRSwNP were recruited from Tongji Hospital and randomly divided into training (n = 232) and internal validation cohort (n = 61). Patients from two additional hospitals served as external validation cohort-1 (n = 84) and cohort-2 (n = 54), respectively. Data were collected from October 2013 to May 2021. Eosinophilic CRSwNP was determined by histological criterion. The least absolute shrinkage and selection operator and the logistic regression (LR) algorithm were used to develop a radiomics model. Univariate and multivariate LR were employed to build models based on CT scores, clinical characteristics, and the combination of radiological and clinical characteristics. Model performance was evaluated by assessing discrimination, calibration, and clinical utility. RESULTS The radiomics model based on 10 radiomic features achieved an area under the curve (AUC) of 0.815 in the training cohort, significantly better than the CT score model based on ethmoid-to-maxillary sinus score ratio with an AUC of 0.655. The combination of radiomic features and blood eosinophil count had a further improved performance, achieving an AUC of 0.903. The performance of these models was confirmed in all validation cohorts with satisfying predictive calibration and clinical application value. CONCLUSIONS A CT radiomics-based model is promising to identify eosinophilic CRSwNP. This radiomics-based method may provide novel insights in solving other clinical concerns, such as guiding personalized treatment and predicting prognosis in patients with CRSwNP.

Abstract
Abstract
Background
Genes related to the SWItch/sucrose nonfermentable (SWI/SNF) chromatin remodeling complex are frequently mutated across cancers. SWI/SNF-mutant tumors are vulnerable to synthetic lethal inhibitors. However, the landscape of SWI/SNF mutations and their associations with tumor mutational burden (TMB), microsatellite instability (MSI) status, and response to immune checkpoint inhibitors (ICIs) have not been elucidated in large real-world Chinese patient cohorts.
Methods
The mutational rates and variation types of six SWI/SNF complex genes (ARID1A, ARID1B, ARID2, SMARCA4, SMARCB1, and PBRM1) were analyzed retrospectively by integrating next-generation sequencing data of 4591 cases covering 18 cancer types. Thereafter, characteristics of SWI/SNF mutations were depicted and the TMB and MSI status and therapeutic effects of ICIs in the SWI/SNF-mutant and SWI/SNF-non-mutant groups were compared.
Results
SWI/SNF mutations were observed in 21.8% of tumors. Endometrial (54.1%), gallbladder and biliary tract (43.4%), and gastric (33.9%) cancers exhibited remarkably higher SWI/SNF mutational rates than other malignancies. Further, ARID1A was the most frequently mutated SWI/SNF gene, and ARID1A D1850fs was identified as relatively crucial. The TMB value, TMB-high (TMB-H), and MSI-high (MSI-H) proportions corresponding to SWI/SNF-mutant cancers were significantly higher than those corresponding to SWI/SNF-non-mutant cancers (25.8 vs. 5.6 mutations/Mb, 44.3% vs. 10.3%, and 16.0% vs. 0.9%, respectively; all p < 0.0001). Furthermore, these indices were even higher for tumors with co-mutations of SWI/SNF genes and MLL2/3. Regarding immunotherapeutic effects, patients with SWI/SNF variations showed significantly longer progression-free survival (PFS) rates than their SWI/SNF-non-mutant counterparts (hazard ratio [HR], 0.56 [95% confidence interval {CI} 0.44–0.72]; p < 0.0001), and PBRM1 mutations were associated with relatively better ICI treatment outcomes than the other SWI/SNF gene mutations (HR, 0.21 [95% CI 0.12–0.37]; p = 0.0007). Additionally, patients in the SWI/SNF-mutant + TMB-H (HR, 0.48 [95% CI 0.37–0.54]; p < 0.0001) cohorts had longer PFS rates than those in the SWI/SNF-non-mutant + TMB-low cohort.
Conclusions
SWI/SNF complex genes are frequently mutated and are closely associated with TMB-H status, MSI-H status, and superior ICI treatment response in several cancers, such as colorectal cancer, gastric cancer, and non-small cell lung cancer. These findings emphasize the necessity and importance of molecular-level detection and interpretation of SWI/SNF complex mutations.

Abstract
The current study aimed to investigate the clinical feasibility of microscopic resection of hemilateral tuberculum sellae meningiomas (TSM) via the contralateral eye brow arch approach. The clinical data of 34 patients with TSM who underwent microsurgery from January 2016 to June 2021 in the Neurosurgery Department of Ruijin Hospital Affiliated to Shanghai Jiaotong University School of Medicine and the First Affiliated Hospital of Henan University were collected and reviewed. The postoperative visual acuity improvement rate was 88.5% (23/26), and the total tumor resection rate was 88.2% (30/34); the postoperative visual acuity improvement in patients with total tumor resection was better than that of patients with partial resection [90.9% (20/22) vs 3/4]. Meanwhile, the postoperative visual acuity improvement in patients with the superior optic nerve and laterl-superior optic nerve was better than that of patients with the lateral optic nerve type (12/14, 8/8 vs 3/4). Supraorbital skin numbness occurred in 3 cases after operation, and the symptoms disappeared during follow-up; 2 cases had mild disturbance of hormone level, and urine output of 2 cases increased after operation, which returned to normal level after symptomatic treatment; 1 case had subcutaneous effusion which was absorbed after treatment. There were no complications such as olfactory disturbance and intracranial infection. During follow-up for 3-60 (33±6) months, recurrence occurred in 2 cases and reoperation was performed. For the hemilateral TSM, according to the preoperative evaluation of the origin of the TSM and the side with visual impairment, the contralateral eyebrow approach is selected to fully expose the tumor base below the optic nerve. It is beneficial to fully resect the tumor under direct vision, and the symptoms of postoperative visual impairment are significantly improved, indicating that the current surgical method can be used in the clinical setting.

Abstract
OBJECTIVE To explore the transcriptional regulation mechanism and biological function of low expression of vasoactive intestinal peptide receptor 1 (VIPR1) in hepatocellular carcinoma (HCC). METHODS We constructed plasmids carrying wild-type VIPR1 promoter or two mutant VIPR1 promoter sequences for transfection of the HCC cell lines Hep3B and Huh7, and examined the effect of AP-2α expression on VIPR1 promoter activity using dual-luciferase reporter assay. Pyrosequencing was performed to detect the changes in VIPR1 promoter methylation level in HCC cells treated with a DNA methyltransferase inhibitor (DAC). Chromatin immunoprecipitation was used to evaluate the binding ability of AP-2α to VIPR1 promoter. Western blotting was used to assess the effect of AP-2α knockdown on VIPR1 expression and examine the differential expression of VIPR1 in the two cell lines. The effects of VIPR1 overexpression and knockdown on the proliferation, cell cycle and apoptosis of HCC cells were analyzed using CCK8 assay and flow cytometry. We also observed the growth of HCC xenograft with lentivirus-mediated over-expression of VIPR1 in nude mice. RESULTS Compared with the wild-type VIPR1 promoter group, co-transfection with the vector carrying two promoter mutations and the AP-2α-over-expressing plasmid obviously restored the luciferase activity in HCC cells (P < 0.05). DAC treatment of the cells significantly decreased the methylation level of VIPR1 promoter and inhibited the binding of AP-2α to VIPR1 promoter (P < 0.01). The HCC cells with AP-2α knockdown showed increased VIPR1 expression, which was lower in Huh7 cells than in Hep3B cells. VIPR1 overexpression in HCC cells caused significant cell cycle arrest in G2/M phase (P < 0.01), promoted cell apoptosis (P < 0.001), and inhibited cell proliferation (P < 0.001), while VIPR1 knockdown produced the opposite effects. In the tumor-bearing nude mice, VIPR1 overexpression in the HCC cells significantly suppressed the increase of tumor volume (P < 0.001) and weight (P < 0.05). CONCLUSION VIPR1 promoter methylation in HCC promotes the binding of AP-2α and inhibits VIPR1 expression, while VIPR1 overexpression causes cell cycle arrest, promotes cell apoptosis, and inhibits cell proliferation and tumor growth.

Abstract
Plants of the Elaeagnaceae family are widely used to treat various health disorders owing to their natural phytochemicals. Seabuckthorn (Hippophae rhamnoides L.) is an economically and ecologically important species within the family with richness of biologically and pharmacologically active substances. Here, we present a chromosome-level genome assembly of seabuckthorn (http://hipp.shengxin.ren/), the first genome sequence of Elaeagnaceae, which has a total length of 849.04 Mb with scaffold N50 of 69.52 Mb and 30 864 annotated genes. Two sequential tetraploidizations with one occurring ~36-41 million years ago (Mya) and the last ~24-27 Mya were inferred, resulting in expansion of genes related to ascorbate and aldarate metabolism, lipid biosynthesis, and fatty acid elongation. Comparative genomic analysis reconstructed the evolutionary trajectories of the seabuckthorn genome with the predicted ancestral genome of 14 proto-chromosomes. Comparative transcriptomic and metabonomic analyses identified some key genes contributing to high content of polyunsaturated fatty acids and ascorbic acid (AsA). Additionally, we generated and analysed 55 whole-genome sequences of diverse accessions, and identified 9.80 million genetic variants in the seabuckthorn germplasms. Intriguingly, genes in selective sweep regions identified through population genomic analysis appeared to contribute to the richness of AsA and fatty acid in seabuckthorn fruits, among which GalLDH, GMPase and ACC, TER were the potentially major-effect causative genes controlling AsA and fatty acid content of the fruit, respectively. Our research offers novel insights into the molecular basis underlying phytochemical innovation of seabuckthorn, and provides valuable resources for exploring the evolution of the Elaeagnaceae family and molecular breeding.

Abstract
Abstract
Study question
What is the the pregnancy outcome after laparoscopy treatment for subtle distal fallopian tube abnormalities and the factors related with natural pregnancy.
Summary answer
The natural pregnancy rate is 46.58% after laparoscopy and patients' age, duration time of infertility and concurrent number of abnormalities are related with natural pregnancy.
What is known already
Subtle distal fallopian tube abnormalities are a group of diseases that are characterized by subtle variations in tubal anatomy including fimbrial agglutination, tubal diverticula, accessory ostium, fimbrial phimosis, and accessory fallopian tube. The prevalence of subtle distal fallopian tube abnormalities is high in infertile women.This group of diseases is highly related to endometriosis, especially its early stage, and may indicate fimbrial abnormalities in endometriosis.
Study design, size, duration
This was a prospective cohort study conducted in the Reproductive Medicine Center of an university-affiliated teaching hospital from January 2017 to December 2018.
Participants/materials, setting, methods
234 patients with subtle distal fallopian tube abnormalities were included. Laparoscopies were performed by four senior reproductive surgeons who were familiar with the diagnostic criteria and surgery treatment for subtle abnormalities. The fallopian tube abnormalities were corrected and endometriosis was treated by either electrical ablation for peritoneal lesions or endometrioma excision.The participants were followed up by phone every 12 months for pregnancy outcome until 36 months after surgery.
Main results and the role of chance
167 patients conceived after surgery(clinical pregnancy rate 71.37%). 109 patients conceived naturally (natural pregnancy rate 46.58%) and 59 patients conceived after in IVF(One case conceived naturally after live birth after IVF, four cases conceived naturally twice) . The average time for natural conception after surgery is 8.36±7.47 months. 51.4% of natural pregnancy occurred within 6 months and 79.8% occurred within 12 months.Among the 109 naturally conceived patients, there were 94 cases of live birth, 13 cases of natural abortion (natural abortion rate 11.92%) and 2 cases of ectopic pregnancy (ectopic pregnancy rate 1.83%). No preterm birth, multiple pregnancy or birth defects were reported in this group.The patient age(HR = 0.917,95%CI 0.870-0.917,P=0.001), duration of infertility(HR = 0.846,95%CI 0.740-0.966,P=0.014) and concurrent number of subtle abnormalities (HR = 0.636,95%CI 0.416-0.970,P=0.036) are the factors associated with natural pregnancy. The type of subtle abnormalities, type of infertility, body mess index, concurrent endometriosis, uterine cavity abnormalities and myoma are not related with natural pregnancy.
Limitations, reasons for caution
Not all kinds of subtle distal abnormalities are included such as paratubal cyst is excluded from the study. Not all the patients had the test of ovarian reserve such as AMH, antral follicle count and FSH level, so we couldn’t evaluate the relationship between ovarian reserve and natural pregnancy.
Wider implications of the findings
This is the largest clinical study that investigated the pregnancy outcome of subtle fallopian tube abnormalities in the infertile population.Laparoscopy surgery is an effective treatment for infertility patients with subtle distal fallopian tube abnormalities, especially for the young, short duration time of infertility and ≤2 types of subtle abnormalities.

Abstract
Study question
Whether hysteroscopic niche resection is suitable for patients with a niche in the uterine cesarean scar and with fertility desire compared with expectant management.
Summary answer
Hysteroscopic niche resection is a effective treatment for patients with fertility desire compared with expectant management and satisfactory obstetrical outcomes could be achieved.
What is known already
The specific treatment method for niche should be determined according to the patient’s symptoms, fertility desire and niche features,up to now, hysteroscopic niche resection has been shown effective to reduce abnormal uterine bleeding. However, similar to expectant treatment, hysteroscopic niche resection does not reconstruct the lower uterine segment, whether hysteroscopic niche resection affect fertility outcomes remains controversial.
Study design, size, duration
We designed a single-center retrospective cohort study. We included patients with desire to conceive that underwent hysteroscopic niche resection or expectant management between 2016.9-2020.12. The date of entry for each woman was the date of treatment or the date that the niche was diagnosed. The last day of analysis was the date of the first delivery or the last follow-up visit in women who remained non-livebirth.
Participants/materials, setting, methods
This study was conducted in a university-affiliated gynecology hospital. A total of 71 patients that underwent hysteroscopic niche resection and 97 patients that underwent expectant management were recruited. All women were followed up yearly until December 2021 for the occurrence of live birth. A Cox proportional hazards regression model with potential variables to identify predictors of pregnancy was also processed.
Main results and the role of chance
Baseline characteristics of age, gravidity, parity, previous cesarean section, and anatomical indicators of niche were not significantly different between the groups. However patients in the hysteroscopic niche resection had a longer menstruation duration (hysteroscopic niche resection vs expectant management as 12(10/14) vs 7(7/10), P <0.001) and a longer infertility period before treatment(hysteroscopic niche resection vs expectant management as 48.00±36.28 vs 23.11±20.34, P = 0.014). The overall live birth rate was similar in both groups (hysteroscopic niche resection vs expectant management as 37/71 [52.11%] vs 40/97 [41.23%], P = 0.162). For the live births in the two groups, no uterine rupture occurred.The total pregnancy rate was higher in the hysteroscopic niche resection group (hysteroscopic niche resection vs expectant management as 50/71 [70.40%] vs 50/97 [51.54%], P = 0.014). What’s more, for patients with infertility before treatment,there was a statistically significant difference regarding time to pregnancy between the two groups (P = 0.049).
After adjustment for confounding factors including age, numbers of cesarean section, infertility peroid before treatment, anatomical indicators of niche and menstruation duration, cox proportional hazards analysis revealed that women underwent hysteroscopic niche resection were positively correlated to pregnancy (AHR = 1.646, 95% CI [1.081-2.506]).
Limitations, reasons for caution
This study was a single-center retrospective cohort study, to strengthen the conclusion, more prospective studies that include larger sample sizes and multiple centers should be conducted.
Wider implications of the findings
For asymptomatic cesarean scar defect patients whose residual myometrium thickness is sufficient, the expectant treatment is practical. However, for patients with abnormal uterine bleeding or infertility, hysteroscopic niche resection should be recommended.

Abstract
Abstract
Study question
What is the intention rate and related factors for a second or third child among childbearing couple?
Summary answer
Among couples with one child, 16.2% are willing to have a second child. Only 9.4% of couples with two children are pursuing third child.
What is known already
The decline in fertility is becoming an inevitable trend in most countries around the world. In the end of 1970s, the one-child policy was implemented. Since 21st century, China has gradually changed its fertility policy, from a selective two-child policy to a comprehensive two-child policy. Nevertheless, the number of total annual births in China has not shown an obviously increasing trend of growth. On August 20, 2021, the Chinese government amended the law to allow a couple to have three children. However, only a few studies have been conducted to evaluate fertility intention in the couples who already have kids.
Study design, size, duration
We conducted a cross-sectional survey in Shanghai from July to August in 2021. This study population was based on the female fertility database established between 2013 and 2017, which contains basic sociodemographic information and the reproductive intentions. We conducted this study to evaluate the fertility intention of the second or the third child and its related factors.
Participants/materials, setting, methods
From July to August in 2021, couples aged between 20 and 45 years old with one or two children was invited to participate in our study to give the information about “second/third births intention” and the factors that may probably related to it. Between the groups with and without second/third child intention, the chi-squared test and binary logistic regression was applied to compare the difference in the basic characteristics and relative factors.
Main results and the role of chance
Among couples with one child, 130 (16.2%) couples had intention to have a second child. Only 9.4% of couples with two children show the desire to have a third child. The ideal number of children for all our participants was 1.72±0.52. And the ideal number of children among couples with one child is 1.61±0.52. By contrast, the ideal number for couples with two kids was 2.06±0.34. The study showed great differences in Socioeconomic and personal factors between two groups. For second-child intention, the female age over 35 years, first child's age over 7 years, annual payment for the first child ranges from 70,000-100,000 RMB and children’s educational barriers were negatively associated with an intention to have a second child. Job with more free time makes it easier for couples to have a second child. Among couples with two children, parents with family financial constraints and children’s educational barriers are less likely to have a third child. Fertility-encouraged government policy can promote couples to pursue a second or third child. It is necessary to take measures to reduce the burden of raising children and increase free time for couples to relief parent’s pressure of rearing a child.
Limitations, reasons for caution
As this is a single-center study in Shanghai, the sample size is relatively small. Although our sample size still meets the basic statistical requirements and can detect a moderate effect size as significance, the results may not be applicable to some other regions.
Wider implications of the findings
The decision of fertility intention is influenced by female age, the first child’s age, family economic conditions, children’s education and national fertility policies. It is necessary to take measures to reduce the burden of raising children and increase free time for couples to relief parent’s pressure of rearing a child.

Abstract
As a new epigenetic mark, DNA N6-adenine (6mA) methylation plays an important role in various biological processes and has been reported in many prokaryotic organisms in recent years. However, the distribution patterns and functions of DNA 6mA modification have been poorly studied in non-model crops. In this study, we observed that the methylation ratio of 6mA was about 0.016% in the sea buckthorn (Hippophae rhamnoides L.) genome using mass spectrometry. We first constructed a comprehensive 6mA landscape in sea buckthorn genome using nanopore sequencing at single-base resolution. Distribution analysis suggested that 6mA methylated sites were widely distributed in the sea buckthorn chromosomes, which were similar to those in Arabidopsis and rice. Furthermore, reduced 6mA DNA methylation is associated with different expression of genes related to the fruit-ripening process in sea buckthorn. Our results revealed that 6mA DNA modification could be considered an important epigenomic mark and contributes to the fruit ripening process in plants.

Abstract
Sea buckthorn is a typical drought-resistant tree species. However, there is a general lack of understanding of the pattern of DNA methylation linked with sea buckthorn responses to drought, and its relationship with drought tolerance mechanisms. In this study, we performed whole-transcriptome RNA sequencing and methylome sequencing in response to drought stress to explore differentially expressed mRNAs, miRNAs, lncRNAs and circRNAs in sea buckthorn leaves. Based on predicted DE pairs, we constructed a competitive endogenous RNA network, which revealed potential transcriptional regulatory roles in response to drought stress. The results of methylome sequencing revealed that the DNA methylation level was increased in sea buckthorn leaves under drought stress. We identified 13,405 differentially methylated regions between CK and TR. We found one DMR-associated DEG (Vacuolar-sorting receptor 6) involved in the ABA accumulation pathway. In addition, two DNA methyltransferases (HrMET1 and HrDRM1) were closely associated with drought-induced hypermethylation in sea buckthorn. Together, we firstly conducted a comprehensive transcriptomic and epigenetic analysis of sea buckthorn under drought stress, providing a resource for further study of the potential functions of genes, miRNAs, lncRNAs, circRNAs and DNA methyltransferases.

Abstract
Objective: To assess the clinical features and treatment outcomes in patients with primary ovarian squamous cell carcinoma (POSCC). Methods: Fifteen patients with primary ovarian squamous cell carcinoma diagnosed from January 2009 to December 2018 in Cancer Hospital of the University of Chinese Academy of Sciences were collected. The expression of p16, hMLH1, hMSH2, hMSH6 and PMS2 in POSCC was detected by immunohistochemistry, and the status of high-risk human papillomavirus (HPV) by RNAscope test. Results: Squamous cell carcinoma with different degrees of differentiation was found in 15 cases, including three cases with high differentiation and 12 cases with medium to low differentiation. There were four cases with in situ squamous cell carcinoma, four cases with teratoma, one case with endometrial carcinoma/atypical hyperplasia, and one case with endometriosis. p16 was expressed in five cases (5/15), indicating coexisting high-risk HPV infection. There was no high-risk HPV infection in the remaining 10 cases, and p16 staining was negative. There was no deficient mismatch repair protein in all cases. The overall survival time (P=0.038) and progression free survival (P=0.045) of patients with high-risk HPV infection were longer than those without HPV infection. Conclusions: POSCC is more commonly noted in postmenopausal women and often occurs unilaterally. Elevated serological indexes CA125 and SCC are the most common finding. Morphologically, the tumors show variable degrees of differentiation, but the current data suggest that the degree of differentiation cannot be used as an independent prognostic index. High-risk HPV infection may be associated with the occurrence of POSCC, and that the prognosis of POSCC patients with HPV infection is better than that of patients without infection.

Abstract
In plants, recent studies have revealed that N6-methyladenosine (m6A) methylation of mRNA has potential regulatory functions of this mRNA modification in many biological processes. m6A methyltransferase, m6A demethylase and m6A-binding proteins can cause differential phenotypes, indicating that m6A may have critical roles in the plant. In this study, we depicted the m6A map of sea buckthorn (Hippophae rhamnoides Linn.) transcriptome. Similar to A. thaliana, m6A sites of sea buckthorn transcriptome is significantly enriched around the stop codon and within 3'-untranslated regions (3'UTR). Gene ontology analysis shows that the m6A modification genes are associated with metabolic biosynthesis. In addition, we identified 13,287 different m6A peaks (DMPs) between leaf under drought (TR) and control (CK) treatment. It reveals that m6A has a high level of conservation and has a positive correlation with mRNA abundance in plants. GO and KEGG enrichment results showed that DMP modification DEGs in TR were particularly associated with ABA biosynthesis. Interestingly, our results showed three m6A demethylase (HrALKBH10B, HrALKBH10C and HrALKBH10D) genes were significantly increased following drought stress, which indicated that it may contributed the decreased m6A levels. This exhaustive m6A map provides a basis and resource for the further functional study of mRNA m6A modification in abiotic stress.

Coordination of diverse individuals often requires sophisticated communications and high-order computational abilities. Microbial populations can exhibit diverse individualistic behaviors, and yet can engage in collective migratory patterns with a spatially sorted arrangement of phenotypes. However, it is unclear how such spatially sorted patterns emerge from diverse individuals without complex computational abilities. Here, by investigating the single-cell trajectories during group migration, we discovered that, despite the constant migrating speed of a group, the drift velocities of individual bacteria decrease from the back to the front. With a Langevin-type modeling framework, we showed that this decreasing profile of drift velocities implies the spatial modulation of individual run-and-tumble random motions, and enables the bacterial population to migrate as a pushed wave front. Theoretical analysis and stochastic simulations further predicted that the pushed wave front can help a diverse population to stay in a tight group, while diverse individuals perform the same type of mean reverting processes around centers orderly aligned by their chemotactic abilities. This mechanism about the emergence of orderly collective migration from diverse individuals is experimentally demonstrated by titration of bacterial chemoreceptor abundance. These results reveal a simple computational principle for emergent ordered behaviors from heterogeneous individuals. Organisms living in large groups often have to move together in order to navigate, forage for food, and increase their roaming range. Such groups are often made up of distinct individuals that must integrate their different behaviors in order to migrate in the same direction at a similar pace. For instance, for the bacteria Escherichia coli to travel as a condensed group, they must coordinate their response to a set of chemical signals called chemoattractants that tell them where to go. The chemoattractants surrounding the bacteria are unequally distributed so that there is more of them at the front than the back of the group. During migration, each bacterium moves towards this concentration gradient in a distinct way, spontaneously rotating its direction in a ‘run-and-tumble’ motion that guides it towards areas where there are high levels of these chemical signals. In addition to this variability, how well individual bacteria are able to swim up the gradient also differs within the population. Bacteria that are better at sensing the chemoattractant gradient are placed at the front of the group, while those that are worst are shifted towards the back. This spatial arrangement is thought to help the bacteria migrate together. But how E. coli organize themselves in to this pattern is unclear, especially as they cannot communicate directly with one another and display such diverse, randomized behaviors. To help answer this question, Bai, He et al. discovered a general principle that describes how single bacterial cells move within a group. The results showed that E. coli alter their run-and-tumble motion depending on where they reside within the population: individuals at the rear drift faster so they can catch up with the group, while those leading the group drift slower to draw themselves back. This ‘reversion behavior’ allows the migrating bacteria to travel at a constant speed around a mean position relative to the group. A cell’s drifting speed is determined by how well it moves towards the chemoattractant and its response to the concentration gradient. As a result, the mean position around which the bacterium accelerates or deaccelerates will vary depending on how sensitive it is to the chemoattractant gradient. The E. coli therefore spatially arrange themselves so that the more sensitive bacteria are located at the front of the group where the gradient is shallower; and cells that are less sensitive are located towards the back where the gradient is steeper. These findings suggest a general principle for how bacteria form ordered patterns whilst migrating as a collective group. This behavior could also apply to other populations of distinct individuals, such as ants following a trail or flocks of birds migrating in between seasons.

Abstract
BACKGROUND Although China accounts for 7.8% of worldwide new prostate cancer (PCa) cases and 14.5% of new deaths according to GLOBOCAN 2020, the risk of PCa associated with germline mutations is poorly defined, hampered in part by lack of nationwide evidence. Here, we sequenced 19 PCa predisposition genes in 1,836 Chinese patients with PCa and estimated disease risk associated with inherited mutations. PATIENTS AND METHODS Patients were recruited from 4 tertiary cancer centers (n=1,160) and a commercial laboratory (n=676). Germline DNA was sequenced using a multigene panel, and pathogenic/likely pathogenic (P/LP) mutation frequencies in patients with PCa were compared with populations from the gnomAD (Genome Aggregation Database) and ChinaMAP (China Metabolic Analytics Project) databases. Clinical characteristics and progression-free survival were assessed by mutation status. RESULTS Of 1,160 patients from hospitals, 89.7% had Gleason scores ≥8, and 65.6% had metastases. P/LP mutations were identified in 8.49% of Chinese patients with PCa. Association with PCa risk was significant for mutations in ATM (odds ratio [OR], 5.9; 95% CI, 3.1-11.1), BRCA2 (OR, 15.3; 95% CI, 10.0-23.2), MSH2 (OR, 15.8; 95% CI, 4.2-59.6), and PALB2 (OR, 5.9; 95% CI, 2.7-13.2). Compared with those without mutations, patients with mutations in ATM, BRCA2, MSH2, or PALB2 showed a poor outcome with treatment using androgen deprivation therapy and abiraterone (hazard ratio, 2.19 [95% CI, 1.34-3.58] and 2.47 [95% CI, 1.23-4.96], respectively) but similar benefit from docetaxel. CONCLUSIONS The present multicenter study confirmed that a significant proportion of Chinese patients with PCa had inherited mutations and identified predisposition genes in this underreported ethnicity. These data provide empirical evidence for precision prevention and prognostic estimation in Chinese patients with PCa.

Abstract
Abstract
Background
Late left ventricular remodeling (LLVR) after the index acute myocardial infarction (AMI) is a common complication, and is associated with poor outcome. However, the optimal definition of LLVR has been debated because of its different incidence and influence on prognosis. At present, there are limited data regarding the influence of different LLVR definitions on long-term outcomes in AMI patients undergoing percutaneous coronary intervention (PCI).
Purpose
To explore the impact of different definitions of LLVR on long-term mortality, re-hospitalization or an urgent visit for heart failure, and identify which definition was more suitable for predicting long-term outcomes in AMI patients undergoing PCI.
Methods
We prospectively observed 460 consenting first-time AMI patients undergoing PCI from January 2012 to December 2018. LLVR was defined as a ≥20% increase in left ventricular end-diastolic volume (LVEDV), or a >15% increase in left ventricular end-systolic volume (LVESV) from the initial presentation to the 3–12 months follow-up, or left ventricular ejection fraction (LVEF) <50% at follow up. These parameters of the cardiac structure and function were measuring through the thoracic echocardiography. The association of LLVR with long-term prognosis was investigated by Cox regression analysis.
Results
The incidence rate of LLVR was 38.1% (n=171). The occurrence of LLVR according to LVESV, LVEDV and LVEF definition were 26.6% (n=117), 31.9% (n=142) and 11.5% (n=51), respectively. During a median follow-up of 2 years, after adjusting other potential risk factors, multivariable Cox regression analysis revealed LLVR of LVESV definition [hazard ratio (HR): 2.50, 95% confidence interval (CI): 1.19–5.22, P=0.015], LLVR of LVEF definition (HR: 16.46, 95% CI: 6.96–38.92, P<0.001) and LLVR of Mix definition (HR: 5.86, 95% CI: 2.45–14.04, P<0.001) were risk factors for long-term mortality, re-hospitalization or an urgent visit for heart failure. But only LLVR of LVEF definition was a risk predictor for long-term mortality (HR: 6.84, 95% CI: 1.98–23.65, P=0.002).
Conclusions
LLVR defined by LVESV or LVEF may be more suitable for predicting long-term mortality, re-hospitalization or an urgent visit for heart failure in AMI patients undergoing PCI. However, only LLVR defined by LVEF could be used for predicting long-term mortality.

Abstract
Abstract
Background
Although previous studies have demonstrated that neutrophil and albumin are biomarkers of inflammation and malnutrition, which are highly related with contrast-associated acute kidney injury (CA-AKI). However, there has been no study investigated the combined evaluation of neutrophil and albumin in predicting CA-AKI.
Purpose
To explore the predictive value of neutrophil percentage-to-albumin ratio (NPAR) for CA-AKI in patients undergoing elective percutaneous coronary intervention (PCI).
Methods
We prospectively observed 5083 consenting patients without chronic kidney disease (CKD) undergoing elective PCI from January 2012 to December 2018. NPAR was calculated as neutrophil percentage numerator divided by serum albumin concentration. CA-AKI was defined as an increase in serum creatinine (SCr) ≥50% or 0.3 mg/dL within 48 hours after contrast medium exposure. The association between NPAR and CA-AKI was investigated by logistic regression analysis. The area under the receiver-operating characteristic curve (AUC), continuous net reclassification improvement (NRI), and integrated discrimination improvement (IDI) were calculated to make comparison for CA-AKI prediction.
Result
The incidence of CA-AKI was 5.6% (n=286). The median NPAR was 14.9 (13.0–17.1). According to the receiver operating characteristic curves (ROC), the best cut-off value of NPAR for predicting CA-AKI was 15.7 with 66.8% sensitivity and 61.9% specificity (C statistic=0.679; 95% CI, 0.666–0.691). NPAR displayed higher AUC value in comparison to neutrophil percentage (p<0.001), but not albumin (P=0.063), as a predictor of CA-AKI. However, NPAR significantly improved the prediction of CA-AKI in the continuous NRI and IDI over neutrophil percentage (NRI: 0.353, 95% CI: 0.234–0.472, P<0.001; IDI: 0.017, 95% CI: 0.010–0.024, p<0.001) and albumin (NRI: 0.141, 95% CI: 0.022–0.260, P=0.020; IDI: 0.009, 95% CI: 0.003–0.015, p=0.003) alone. After adjusting for potential confounding risk factors of CA-AKI, multivariable logistic analysis showed that NPAR >15.7 was a strong independent predictor of CA-AKI (OR=1.998, 95% CI, 1.511–2.643, p<0.001).
Conclusion
NPAR is an independent predictor of CA-AKI, which significantly improved the prediction of CA-AKI over neutrophil and albumin alone in patients without CKD undergoing elective PCI.

Abstract
Abstract
Background
Preoperative liver dysfunction has been demonstrated as a poor prognostic factor after major surgery. Recent researches discovered that an increased De-Ritis ratio (aspartate aminotransferase-to-alanine aminotransferase ratio) reflects the liver dysfunction and was associated with adverse cardiovascular and renal outcomes. However, there is a lack of data exploring the predictive value of the De-Ritis ratio on contrast-associated acute kidney injury (CA-AKI) in patients undergoing elective percutaneous coronary intervention (PCI).
Purpose
To evaluate the predictive value of the De-Ritis ratio for CA-AKI in patients undergoing elective PCI.
Methods
We conducted a prospective, observational study with 5780 consenting patients undergoing elective PCI from January 2012 to December 2018. CA-AKI was defined as an increase in serum creatinine (SCr) ≥50% or 0.3 mg/dL within 48 hours after contrast medium exposure. The relationship between the De-Ritis ratio and CA-AKI was investigated by logistic regression analysis. The predictive utility of the De-Ritis ratio was determined and compared using the area under the receiver-operating characteristic curve (AUC).
Result
CA-AKI developed in 363 (6.3%) patients. The median De-Ritis ratio was 1.00 (0.77–1.33). The De-Ritis ratio showed an AUC of 0.636 (95% confidence interval (CI): 0.624–0.649; P<0.001) in predicting CA-AKI, which was significantly greater than aspartate aminotransferase (AST) (AUC: 0.636 vs 0.589, p=0.015) and alanine aminotransferase (ALT) (AUC: 0.636 vs 0.506, p<0.001). The best cut-off value of the De-Ritis ratio for predicting CA-AKI was 1.30 with 47.1% sensitivity and 74.7% specificity. Multivariable logistic analysis showed that the De-Ritis ratio >1.30 was a remarkable independent predictor of CA-AKI (OR=1.757, 95% CI, 1.385–2.229, p<0.001) even after adjusting for other CA-AKI risk factors.
Conclusion
The De-Ritis ratio is an independent risk factor for predicting CA-AKI in patients undergoing elective PCI.

Abstract
Background We report results from the phase I dose-finding and phase II expansion part of a multicenter, open-label study of single-agent lenvatinib in pediatric and young adult patients with relapsed/refractory solid tumors, including osteosarcoma and radioiodine-refractory differentiated thyroid cancer (RR-DTC) (NCT02432274). Patients and methods The primary endpoint of phase I was to determine the recommended phase II dose (RP2D) of lenvatinib in children with relapsed/refractory solid malignant tumors. Phase II primary endpoints were progression-free survival rate at 4 months (PFS-4) for patients with relapsed/refractory osteosarcoma; and objective response rate/best overall response for patients with RR-DTC at the RP2D. Results In phase I, 23 patients (median age, 12 years) were enrolled. With lenvatinib 14 mg/m2, three dose-limiting toxicities (hypertension, n = 2; increased alanine aminotransferase, n = 1) were reported, establishing 14 mg/m2 as the RP2D. In phase II, 31 patients with osteosarcoma (median age, 15 years) and 1 patient with RR-DTC (age 17 years) were enrolled. For the osteosarcoma cohort, PFS-4 (binomial estimate) was 29.0% [95% confidence interval (CI) 14.2% to 48.0%; full analysis set: n = 31], PFS-4 by Kaplan–Meier estimate was 37.8% (95% CI 20.0% to 55.4%; full analysis set) and median PFS was 3.0 months (95% CI 1.8-5.4 months). The objective response rate was 6.7% (95% CI 0.8% to 22.1%). The patient with RR-DTC had a best overall response of partial response. Some 60.8% of patients in phase I and 22.6% of patients in phase II (with osteosarcoma) had treatment-related treatment-emergent adverse events of grade ≥3. Conclusions The lenvatinib RP2D was 14 mg/m2. Single-agent lenvatinib showed activity in osteosarcoma; however, the null hypothesis could not be rejected. The safety profile was consistent with previous tyrosine kinase inhibitor studies. Lenvatinib is currently being investigated in osteosarcoma in combination with chemotherapy as part of a randomized, controlled trial (NCT04154189), in pediatric solid tumors in combination with everolimus (NCT03245151), and as a single agent in a basket study with enrollment ongoing (NCT04447755). The recommended phase II dose of lenvatinib in children with relapsed/refractory solid malignant tumors is 14 mg/m2. This dose is equivalent to the recommended dose of 24 mg/day for single-agent lenvatinib in adults with DTC. Single-agent lenvatinib showed activity of interest in children and young adults with osteosarcoma. Based on this initial report, lenvatinib is currently being investigated in combination with chemotherapy in osteosarcoma.

Abstract
The development and design of clean and efficient water splitting photocatalysts is important for the current situation of energy shortage and environmental pollution. A new type of isomorphic GaSe/InS heterostructure is constructed, and the optoelectronic properties were studied through first-principles calculations. The results show that GaSe/InS vdW heterostructure is a type II semiconductor with a band gap of 2.09 eV. However, through the analysis of the energy band edge position and Gibbs free energy change of water splitting, it is found that the GaSe/InS heterostructure is difficult to undergo overall water splitting. Therefore, nonmetallic element P doping is considered, the established P-doped GaSe/InS (P-GaSe/InS) heterostructure could maintain the type II band arrangement, and under acidic conditions, P-GaSe/InS heterostructure could spontaneously undergo overall water splitting thermodynamically. Furthermore, the low exciton binding energy of P-GaSe/InS heterostructure highlights better light absorption performance. Therefore, these findings indicate that P-GaSe/InS heterostructure is a promising photocatalyst in overall water splitting.

Abstract
Abstract
Study question
What is the comparative effectiveness between salpingectomy and neosalpingostomy in the treatment of bilateral severe hydrosalpinx?
Summary answer
In women with bilateral severe hydrosalpinx, salpingectomy combined with In Vitro Fertilization (IVF) treatment resulted in a higher cumulative live birth rate than neosalpingostomy.
What is known already
Hydrosalpinx accounts for 25% to 35% of female subfertility and has a negative effect on pregnancy rates in women who undergo IVF. So far salpingectomy before in vitro fertilization treatment has been suggested for the treatment of hydrosalpinx in order to improve the chance of a live birth. Previous studies have reported a pooled live birth rate of 25% through natural conception after neosalpingostomy and an ongoing pregnancy rate of 55.8% after salpingectomy with IVF. Direct comparison of the cumulative live birth rate after salpingectomy versus neosalpingostomy, both followed by IVF is lacking.
Study design, size, duration
We performed a single center, prospective comparative cohort study in the International Peace Maternity and Child Health Hospital affiliated to Shanghai Jiao Tong University School of Medicine, China. We studied women diagnosed with tubal subfertility with bilateral hydrosalpinx between January 2005 and December 2012. Based on a shared decision approach, they had bilateral salpingectomy or neosalpingostomy followed by IVF. They were annually followed up until July 2020 for the occurrence of live birth.
Participants/materials, setting, methods
Out of 113 women, 55 had bilateral salpingectomy and 58 had bilateral neosalpingostomy. Primary outcome was cumulative live birth rate, defined as the cumulative birth rate of the first living neonate through either natural conception or in vitro fertilization. Both intention-to-treat (ITT) and per-protocol (PP) analysis were processed. Cox proportional hazards regression model with potential variables was performed to identify predictors of successful live birth.
Main results and the role of chance
Baseline characteristics were comparable between two groups. There were 42 live births in the salpingectomy and 36 in the neosalpingostomy group. When the result of IVF was incorporated (55/55 in salpingectomy group and 25/58 in neosalpingostomy group underwent IVF), salpingectomy resulted in a higher cumulative live birth rate (85.3% vs 76.0%; hazard ratio of the whole survival curve, 2.18; 95% CI, 1.37 - 3.45; P = 0.001), a lower risk of ectopic pregnancy (1.8% vs 20.7%; risk ratio, 0.07; 95% CI, 0.01 - 0.57; P = 0.013), and a shorter time to live birth (19 [14,27] versus 36 [17,76] months, P = 0.001).The number of live birth rates after natural conception was 0% (0/55) in the salpingectomy group and 28% (16/58) in neosalpingostomy group.The results of PP analyses were comparable with the ITT analyses apart from the biochemical pregnancy rate and the overall live birth rate, they were higher (the former: 76% (42/55) versus 58% (29/50), P = 0.045; the latter: 76% (42/55) versus 56% (28/50), P = 0.027) in salpingectomy group.
Limitations, reasons for caution
This is an observational study. The small sample size along with the data was obtained from a cohort study in a single center.
Wider implications of the findings
In women with confirmed bilateral severe hydrosalpinx, salpingectomy followed by IVF results in a higher cumulative live birth rate and decreases the risk of EP as compared to neosalpingostomy. However, neosalpingostomy is the only option to achieve a live birth by natural conception that should be discussed with patients preoperatively.

Abstract
With the aggravation of environmental pollution and the energy crisis, it is particularly important to develop and design environment-friendly and efficient spontaneous enhanced visible-light-driven photocatalysts for water splitting. Herein novel type-II van der Waals (vdW) GaSe/CN and Ga2SSe/CN heterostructures are proposed through first-principles calculations. Their electronic properties and photocatalytic performance are theoretically analyzed. In particular, their appropriate band gap and band-edge position meet the requirements of the oxygen evolution reaction, and the reaction is thermodynamically feasible in most pH ranges. The unique band alignment of these heterostructured photocatalysts leads to high solar-to-hydrogen energy conversion efficiencies up to 15.11%, which has a good commercial application prospect. More excitingly, with the application of 2% biaxial strain, the smooth progress of the water-splitting reaction of the GaSe/CN and Ga2SSe/CN heterostructures can still be maintained, and the carrier mobility and optical absorption characteristics can be effectively improved. Consequently, these findings suggest that the GaSe/CN and Ga2SSe/CN vdW heterostructures have promising potentials as photocatalysts for water splitting. This work may provide a promising clue for the design of efficient and stable photocatalytic water-splitting catalysts under visible spectroscopy.

Abstract
Drought is the most severe abiotic stress and hinders the normal growth and development of plants. Sea buckthorn (Hippophae rhamnoides Linn.) is a typical drought-resistant tree species. In this study, the leaves of the H. rhamnoides ssp. sinensis ('FN') and H. rhamnoides ssp. mongolica ('XY') were selected during drought-recovery cycles for RNA sequencing, and physiological and biochemical analyses. The results revealed that drought stress significantly decreased leaf water potential, net photosynthetic rate and stomatal conductance in both sea buckthorn subspecies. Similarly, the contents of flavone, flavonol, isoflavone and flavanone significantly decreased under drought stress in 'XY'. Conversely, in 'FN', the flavone and abscisic acid (ABA) contents were significantly higher under drought stress and recovered after rehydration. Meanwhile, 4618 and 6100 differentially expressed genes (DEGs) were identified under drought stress in 'FN' and 'XY', respectively. In total, 5164 DEGs were observed in the comparison between 'FN' and 'XY' under drought stress. This was more than the 3821 and 3387 DEGs found when comparing the subspecies under control and rehydration conditions, respectively. These DEGs were mainly associated with carotenoid biosynthesis, flavonoid biosynthesis, photosynthesis and plant hormone signal transduction. Six hub DEGs (ABCG5, ABCG22, ABCG32, ABCG36, ABF2 and PYL4) were identified to respond to drought stress based on weighted gene co-expression network analysis and Basic Local Alignment Search Tool (BLAST) analysis using DroughtDB. These six DEGs were annotated to play roles in the ABA-dependent signaling pathway. Sixteen RNA sequencing results involving eight genes and similar expression patterns (12/16) were validated using quantitative real-time Polymerase Chain Reaction (PCR). The biochemical and molecular mechanisms underlying the regulation of drought responses by ABA and flavonoids in sea buckthorn were clarified. In this study, gene co-expression networks were constructed, and the results suggested that the mutual regulation of ABA and flavonoid signaling contributed to the difference in drought resistance between the different sea buckthorn subspecies.
