Abstract
Objective: This study collected a real-world data on survival and efficacy of gemcitabine-containing therapy in advanced breast cancer. Aimed to find the main reasons of affecting the duration of gemcitabine-base therapy in advanced breast cancer patients. Methods: Advanced breast cancer patients who received gemcitabine-base therapy from January 2017 to January 2019 were enrolled(10 hospitals). The clinicopathological data, the number of chemotherapy cycles and the reasons for treatment termination were collected and analyzed. To identify the reasons related with continuous treatment for advanced breast cancer and the factors which affect the survival and efficacy. Results: A total of 224 patients with advanced breast cancer were enrolled in this study, with a median age of 52 years (26-77 years), 55.4%(124/224) was postmenopausal. Luminal type were 83 cases, TNBC were 97 cases, and human epidermal growth factor receptor 2 (HER's-2) overexpression were 44. At the analysis, 224 patients who received the gemcitabine-based regimens were evaluated, included 5 complete reponse (CR), 77 partial response (PR), 112 stable disease (SD) and 27 progressive disease (PD). The objective response rate (ORR) was 36.6%(82/224). Seventy patients had serious adverse diseases, including leukopenia (9), neutrophilia (49), thrombocytopenia (15), and elevated transaminase (2). The median follow-up time was 41 months (26~61 months), and the median PFS was 5.6 months. The reasons of termination treatment were listed: disease progression were 90 patients; personal reasons were 51 patients; adverse drug reactions were 18 patients; completed treatment were 65 patients. It was found that progression-free survival (PFS) was significantly longer in patients receiving >6 cycles than that in patients with ≤6 cycles (8.2 months vs 5.4 months, HR=2.474, 95% CI: 1.730-3.538, P<0.001). Conclusions: Gemcitabine-based regimen is generally well tolerated in the Chinese population and has relatively ideal clinical efficacy in the real world. The median PFS is significantly prolonged when the number of treatment cycles are appropriately increased.

Abstract
OBJECTIVES Patients with severe stroke are at high risk of developing acute respiratory distress syndrome (ARDS), but this severe complication was often under-diagnosed and rarely explored in stroke patients. We aimed to investigate the prevalence, early predictors, and outcomes of ARDS in severe stroke. METHODS This prospective study included consecutive patients admitted to neurological intensive care unit (neuro-ICU) with severe stroke, including acute ischemic stroke, intracerebral hemorrhage, and subarachnoid hemorrhage. The incidence of ARDS was examined, and baseline characteristics and severity scores on admission were investigated as potential early predictors for ARDS. The in-hospital mortality, length of neuro-ICU stay, the total cost in neuro-ICU, and neurological functions at 90 days were explored. RESULTS Of 140 patients included, 35 (25.0%) developed ARDS. Over 90% of ARDS cases occurred within 1 week of admission. Procalcitonin (OR 1.310 95% CI 1.005-1.707, P = 0.046) and PaO2/FiO2 on admission (OR 0.986, 95% CI 0.979-0.993, P < 0.001) were independently associated with ARDS, and high brain natriuretic peptide (OR 0.994, 95% CI 0.989-0.998, P = 0.003) was a red flag biomarker warning that the respiratory symptoms may be caused by cardiac failure rather than ARDS. ARDS patients had longer stays and higher expenses in neuro-ICU. Among patients with ARDS, 25 (62.5%) were moderate or severe ARDS. All the patients with moderate to severe ARDS had an unfavorable outcome at 90 days. CONCLUSIONS ARDS is common in patients with severe stroke, with most cases occurring in the first week of admission. Procalcitonin and PaO2/FiO2 on admission are early predictors of ARDS. ARDS worsens both short-term and long-term outcomes. The conflict in respiratory support strategies between ARDS and severe stroke needs to be further studied.

Abstract
A transportable, compact, accelerator-based neutron source is under development at Xian Jiaotong University. An electrostatic low energy beam transport (LEBT) structure with a double Einzel-lens setup was adopted due to its short length and low power consumption. It can transport a pulsed proton beam to the radio frequency quadrupole with a required beam current of 15 mA and an energy of 30 keV. We performed detailed structure optimization and beam tracking to achieve beam matching and small emittance growth. In addition, the fast chopper, beam steering, and diagnostic devices are integrated into the LEBT. The fabrication and assembly of the proton injector have been completed, and beam commissioning was carried out to measure the beam current and Twiss parameters. The design strategy, beam simulation, and experimental results are presented and discussed in this paper.

Abstract
Objective: To evaluate the secondary attack rates of the SARS-CoV-2 Omicron variant and the associated factors. Methods: A total of 328 primary cases and 40 146 close contacts of the SARS-CoV-2 Omicron variant routinely detected in local areas of Jiangsu Province from February to April 2022 were selected in this study, and those with positive nucleic acid test results during 7 days of centralized isolation medical observation were defined as secondary cases. The demographic information and clinical characteristics were collected, and the secondary attack rate (SAR) and the associated factors were analyzed by using a multivariate logistic regression model. Results: A total of 1 285 secondary cases of close contacts were reported from 328 primary cases, with a SAR of 3.2% (95%CI: 3.0%-3.4%). Among the 328 primary cases, males accounted for 61.9% (203 cases), with the median age (Q1, Q3) of 38.5 (27, 51) years old. Among the 1 285 secondary cases, males accounted for 59.1% (759 cases), with the median age (Q1, Q3) of 34 (17, 52) years old. The multivariate logistic regression model showed that the higher SAR was observed in the primary male cases (OR=1.632, 95%CI: 1.418-1.877), younger than 20 years old (OR=1.766, 95%CI: 1.506-2.072),≥60 years old (OR=1.869, 95%CI: 1.476-2.365), infected with the BA.2 strain branch (OR=2.906, 95%CI: 2.388-3.537), the confirmed common cases (OR=2.572, 95%CI: 2.036-3.249), and confirmed mild cases (OR=1.717, 95%CI: 1.486-1.985). Meanwhile, the higher SAR was observed in the close contacts younger than 20 years old (OR=2.604, 95%CI: 2.250-3.015),≥60 years old (OR=1.287, 95%CI: 1.052-1.573) and exposure for co-residence (OR=27.854, 95%CI: 23.470-33.057). Conclusion: The sex and age of the primary case of the Omicron variant, the branch of the infected strain, case severity of the primary case, as well as the age and contact mode of close contacts are the associated factors of SAR.

Abstract
With the complexity and diversification of thermoelectric (TE) application scenarios, it becomes increasingly difficult for single-component thermoelectric materials to satisfy practical demands. Therefore, recent researches have largely focused on the development of the multi-component nanocomposites, which are probably a good solution for the TE application of some materials that are not eligible when used alone. In this work, a seires of single-walled carbon nanotube (SWCNT)/polypyrrole (PPy)/tellurium (Te)/lead telluride (PbTe) multi-layer flexible composite films were fabricated via the successive electrodeposition of the flexible PPy layer with a low thermal conductivity, the ultra-thin Te induction layer, and the brittle PbTe layer with a large Seebeck coefficient over the pre-fabricated SWCNT membrane electrode with a high electrical conductivity. Through the complementary advantages between different components and the multiple synergies of the interface engineering, the SWCNT/PPy/Te/PbTe composites harvested the excellent TE performance with a maximum power factor (PF) of 929.8 ± 35.4 µW m-1 K-2 at room temperature, outperforming those of most of the electrochemically-prepared organic/inorganic TE composites reported previously. This work evidenced that the electrochemical multi-layer assembly is a feasible tactic for constructing special thermoelectric materials to meet customized requirements, which could also be applied to other material platforms.

Abstract
The occurrence of acute pancreatitis (AP) is increasing significantly worldwide. However, current diagnostic methods of AP do not provide a clear clinical stratification of severity, and the prediction of complications in AP is still limited. Here, we present a robust AP identification and diagnosis (RAPIDx) method by the proteomic fingerprinting of intact nanoscale extracellular vesicles (EVs) from clinical samples. By tracking analysis of circulating biological nanoparticles released by cells (i.e., EVs) via bottom-up proteomics, we obtain close phenotype connections between EVs, cell types, and multiple tissues based on their specific proteomes and identify the serum amyloid A (SAA) proteins on EVs as potential biomarkers that are differentially expressed from AP patients significantly. We accomplish the quantitative analysis of EVs fingerprints using MALDI-TOF MS and find the SAA proteins (SAA1-1, desR-SAA1-2, SAA2, SAA1-2) with areas under the curve (AUCs) from 0.92 to 0.97, which allows us to detect AP within 30 min. We further realize that SAA1-1 and SAA2, combined with two protein peaks (5290.19, 14032.33 m/z), can achieve an AUC of 0.83 for classifying the severity of AP. The RAPIDx platform will facilitate timely diagnosis and treatment of AP before severity development and persistent organ failure and promote precision diagnostics and the early diagnosis of pancreatic cancer.

Abstract
Triple-negative breast cancer (TNBC) is a heterogeneous disease and lacks effective treatment. Our previous study classified TNBCs into four subtypes with putative therapeutic targets. Here, we report the final results of FUTURE, a phase II umbrella trial designed to explore whether the subtyping-based strategy may improve the outcomes in metastatic TNBC patients. A total of 141 patients with a median of three previous lines of therapies in the metastatic setting were enrolled in seven parallel arms. Confirmed objective responses were achieved in 42 patients (29.8%; 95% confidence interval [CI], 22.4-38.1). The median values of progression-free survival and overall survival were 3.4 (95% CI: 2.7-4.2) and 10.7 (95% CI: 9.1-12.3) months, respectively. Given Bayesian predictive probability, efficacy boundaries were achieved in four arms. Furthermore, integrated genomic and clinicopathological profiling illustrated associations of clinical and genomic parameters with treatment efficacy, and the efficacy of novel antibody-drug conjugates was explored in preclinical TNBC models of subtypes for which treatment was futile. In general, the FUTURE strategy recruits patients efficiently and provides promising efficacy with manageable toxicities, outlining a direction for further clinical exploration.

Abstract
Phosphorus (P), an essential macronutrient for all life on Earth, has been shown to be a vital limiting nutrient element for plant growth and yield. P deficiency is a common phenomenon in terrestrial ecosystems across the world. Chemical phosphate fertilizer has traditionally been employed to solve the problem of P deficiency in agricultural production, but its application has been limited by the non-renewability of raw materials and the adverse influence on the ecological health of the environment. Therefore, it is imperative to develop efficient, economical, environmentally friendly and highly stable alternative strategies to meet the plant P demand. Phosphate-solubilizing bacteria (PSB) are able to improve plant productivity by increasing P nutrition. Pathways to fully and effectively use PSB to mobilize unavailable forms of soil P for plants has become a hot research topic in the fields of plant nutrition and ecology. Here, the biogeochemical P cycling in soil systems are summarized, how to make full use of soil legacy P via PSB to alleviate the global P resource shortage are reviewed. We highlight the advances in multi-omics technologies that are helpful for exploring the dynamics of nutrient turnover and the genetic potential of PSB-centered microbial communities. Furthermore, the multiple roles of PSB inoculants in sustainable agricultural practices are analyzed. Finally, we project that new ideas and techniques will be continuously infused into fundamental and applied research to achieve a more integrated understanding of the interactive mechanisms of PSB and rhizosphere microbiota/plant to maximize the efficacy of PSB as P activators.

Abstract
Abstract
Background: Triple-negative breast cancer (TNBC) is a heterogeneous disease and lacks effective treatment. Our previous study classified TNBCs into four subtypes (luminal androgen receptor [LAR], immunomodulatory [IM], basal-like immune-suppressed [BLIS], mesenchymal-like [MES]) with distinct molecular features. We aimed to assess the efficacy and safety of molecular subtype-derived precision treatment in patients with heavily pretreated metastatic TNBC.
Methods: This open-label, phase 2, umbrella trial included patients from four centers in China. Participants were women (aged ≥18 years) with histologically confirmed metastatic TNBC with disease progression after multiple lines of standard chemotherapy. Patients were enrolled into seven parallel arms according to their molecular subtypes: LAR with or without ERBB2 somatic mutation/amplification assigned to arm A (pyrotinib with capecitabine) and arm B (androgen inhibitor included therapy); IM assigned to arm C (anti-PD-1 antibody with nab-paclitaxel); BLIS with or without BRCA1/2 germline mutation assigned to arms D (PARP inhibitor included therapy) and E (anti-VEGFR included therapy); MES without or with PI3K-AKT mutation assigned to arms F (anti-VEGFR included therapy) and G (everolimus with nab-paclitaxel). Bayesian predictive probability was adopted to monitor each arm, which can be terminated independently according to a prespecified futility or efficacy boundary. This trial is registered with ClinicalTrials.gov, NCT03805399.
Findings: Between October 18, 2018, and February 11, 2022, we enrolled 141 patients. All patients were heavily pretreated and resistant to six categories of the most common chemotherapeutic agents used in breast cancer treatment, with a median of 3 previous lines of therapies in the metastatic setting (Table 1 and 2). The median follow-up was 18.3 months (IQR 11.7-27.7). A confirmed objective response was achieved in 42 (29.8%, 95% CI 22.4-38.1) of the 141 patients. The median PFS was 3.4 months (95% CI 2.7-4.2), and the median OS was 10.7 months (95% CI 9.0-12.3) (Table 3). Arms A, C, E and G achieved efficacy boundaries, with 3 (75.0%) out of 4 patients in arm A, 20 (43.5%) out of 46 patients in arm C, 13 (28.3%) out of 46 patients in arm E, and 3 (33.3%) out of 9 patients in arm G achieving objective responses. Potential predictive biomarkers of efficacy in each arm were explored. Safety data were consistent with the known safety profiles of relevant drugs.
Interpretation: We demonstrate the feasibility and clinical utility of a subtyping-based, genomic sequencing-guided strategy which allows the majority of heavily pretreated metastatic TNBCs to benefit from precision treatment. Most arms exhibit promising efficacy and manageable toxicities, providing subtyping schema to optimize personalized treatment.

Abstract
Abstract
Background: Approximately 10% of patients with HER2-positive breast cancer have primary resistance to trastuzumab, leading to poor prognosis. Although several trials enrolled those hard-to-treat patients, there has been no strong evidence available for the clinical decision making. This multicenter phase 2 trial aimed to investigate the activity and safety of pyrotinib plus capecitabine only in those patients with trastuzumab-resistant, HER2-positive advanced breast cancer. Methods: Patients from 17 sites in China received pyrotinib 400 mg once a day and capecitabine 1000 mg/m2 twice a day on days 1-14 every 21 days until disease progression or intolerable toxicity. Based on the definitions used in prior clinical trials, primary trastuzumab resistance was defined as progression during trastuzumab treatment (Group 1) or within 12 months after completing trastuzumab treatment in the (neo)adjuvant setting (trastzuzumab should have been for ≥9 weeks, Group 2), or progression within 6 months after the initiation of trastuzumab treatment in the advanced setting (treatment should have been for ≥6 weeks, Group 3). The primary endpoint was progression-free survival (PFS). The study is registered with ClinicalTrials.gov, NCT04001621. Results: Between June 2019 and September 2021, a total of 100 patients enrolled; 35 (35.0%) patients had hormone receptor (HR)-positive disease, and 65 (65.0%) had HR-negative disease. Prior use of trastuzumab, pertuzumab and antibody-drug conjugate was reported in 100%, 21.0% and 2.0% of patients, respectively. By the data cutoff on July 10, 2022, the median follow-up duration was 23.4 months (95%CI, 20.5-25.6) with 66 PFS events documented. Median PFS was 11.8 months (95%CI, 8.4-15.1) in the overall population. Patients in Group 2 (n=49) had the longest median PFS of 17.8 months (95%CI, 13.8-not reached), which was significantly different from either 8.2 months (95%CI, 3.0-20.7; p = 0.001) in Group 1 (n=21) or 5.6 months (95%CI, 4.1-6.9; p < 0.001) in Group 3 (n=30). No significant difference in median PFS was observed in subgroup by HR status (HR-positive: 9.7 months [95%CI, 6.4-18.4]; HR-negative: 12.3 months [95%CI, 8.2-17.8]; p = 0.764). Objective response rate was 70.0% (95%CI, 60.0%-78.8%). Overall survival data was immature. The most common grade ≥3 treatment-emergent adverse events included diarrhea (24.0%), palmar-plantar erythrodysaesthesia syndrome (9.0%), neutrophil count decreased (7.0%), hypokalemia (5.0%), and decreased appetite (5.0%). No treatment-related deaths occurred. Conclusions: Pyrotinib plus capecitabine resulted in a promising PFS that crossed the pre-specified efficacy boundary in patients with HER2-positive advanced breast cancer who met the traditional definition of primary trastuzumab resistance. Patients in Group 2 had a significant longer PFS than those in either Group 1 or Group 3, highlighting the need to re-define primary trastuzumab resistance and to clarify efficacy of new anti-HER2 biologicals for each subpopulation.

Abstract
Background Inflammatory mechanisms play important roles in intracerebral hemorrhage (ICH) and have been linked to the development of stroke-associated pneumonia (SAP). The neutrophil-to-lymphocyte ratio (NLR), systemic immune-inflammation index (SII), platelet-to-lymphocyte ratio (PLR) and systemic inflammation response index (SIRI) are inflammatory indexes that influence systemic inflammatory responses after stroke. In this study, we aimed to compare the predictive value of the NLR, SII, SIRI and PLR for SAP in patients with ICH to determine their application potential in the early identification of the severity of pneumonia. Methods Patients with ICH in four hospitals were prospectively enrolled. SAP was defined according to the modified Centers for Disease Control and Prevention criteria. Data on the NLR, SII, SIRI and PLR were collected at admission, and the correlation between these factors and the clinical pulmonary infection score (CPIS) was assessed through Spearman's analysis. Results A total of 320 patients were enrolled in this study, among whom 126 (39.4%) developed SAP. The results of the receiver operating characteristic (ROC) analysis revealed that the NLR had the best predictive value for SAP (AUC: 0.748, 95% CI: 0.695-0.801), and this outcome remained significant after adjusting for other confounders in multivariable analysis (RR=1.090, 95% CI: 1.029-1.155). Among the four indexes, Spearman's analysis showed that the NLR was the most highly correlated with the CPIS (r=0.537, 95% CI: 0.395-0.654). The NLR could effectively predict ICU admission (AUC: 0.732, 95% CI: 0.671-0.786), and this finding remained significant in the multivariable analysis (RR=1.049, 95% CI: 1.009-1.089, P=0.036). Nomograms were created to predict the probability of SAP occurrence and ICU admission. Furthermore, the NLR could predict a good outcome at discharge (AUC: 0.761, 95% CI: 0.707-0.8147). Conclusions Among the four indexes, the NLR was the best predictor for SAP occurrence and a poor outcome at discharge in ICH patients. It can therefore be used for the early identification of severe SAP and to predict ICU admission.

Abstract
Schisandrin B (Scheme B) is the most abundant and active lignan monomer isolated from Schisandra chinensis. At present, most reports focus on its cardioprotective and hepatoprotective effects, however, the related reports on gastrointestinal protective effects are still limited. The study aims to evaluate the protective effect of Scheme B on cisplatin-induced rat intestinal crypt epithelial (IEC-6) cell injury and the possible molecular mechanisms. The results showed that Scheme B at 2.5, 5 and 10 μM could inhibit dose-dependently the reduction of cell activity induced by cisplatin exposure at 1 μM, decrease the levels of reactive oxygen species (ROS) and malondialdehyde (MDA), while increasing glutathione (GSH), superoxide dismutase (SOD) and catalase (CAT) to alleviate oxidative stress injury in IEC-6 cell lines. Meanwhile, Scheme B could relieve cisplatin-induced apoptosis by regulating PI3K/AKT and the downstream caspase signaling pathway. The results from flow cytometry analysis and mitochondrial membrane potential (MMP) staining also demonstrated the anti-apoptosis effect of Scheme B. Furthermore, Scheme B was found to reduce the inflammation associated with cell damage by evaluating the protein expressions of the nuclear factor-kappa B (NF-κB) signaling pathway. Importantly, Wnt/β-catenin, as a functional signaling pathway that drives intestinal self-recovery, was also in part regulated by Scheme B. In conclusion, Scheme B might alleviate cisplatin-induced IEC-6 cell damage by inhibiting oxidative stress, apoptosis, inflammation, and repairing intestinal barrier function. The present research provides a strong evidence that Scheme B may be a useful modulator in cisplatin-induced intestinal toxicity.

Abstract
The Asian long-horned beetle, Anoplophora glabripennies (Motschulsky), is a destructive wood-boring pest that is capable of killing healthy trees. Gut bacteria in the larvae of the wood-boring pest is essential for the fitness of hosts. However, little is known about the structure of the intestinal microbiome of A. glabripennies during larval development. Here, we used Illumina MiSeq high-throughput sequencing technology to analyze the larval intestinal bacterial communities of A. glabripennies at the stages of newly hatched larvae, 1st instar larvae and 4th instar larvae. Significant differences were found in larval gut microbial community structure at different larvae developmental stages. Different dominant genus was detected during larval development. Acinetobacter were dominant in the newly hatched larvae, Enterobacter and Raoultella in the 1st instar larvae, and Enterococcus and Gibbsiella in the 4th instar larvae. The microbial richness in the newly hatched larvae was higher than those in the 1st and 4th instar larvae. Many important functions of the intestinal microbiome were predicted, for example, fermentation and chemoheterotrophy functions that may play an important role in insect growth and development was detected in the bacteria at all tested stages. However, some specific functions are found to be associated with different development stages. Our study provides a theoretical basis for investigating the function of the intestinal symbiosis bacteria of A. glabripennies.

Abstract
OBJECTIVE Early identification and intervention for children with global developmental delay (GDD) can significantly improve their prognosis and reduce the possibility of developing intellectual disability in the future. This study aimed to explore the clinical effectiveness of a parent-implemented early intervention program (PIEIP) for GDD, providing a research basis for the extended application of this intervention strategy in the future. METHODS During the period between September 2019 and August 2020, children aged 3 to 6 months diagnosed with GDD were selected from each research center as the experimental group and the control group. For the experimental group, the PIEIP intervention was conducted for the parent-child pair. Mid-term and end-stage assessments were performed, respectively, at 12 and 24 months of age, and parenting stress surveys were completed. RESULTS The average age of the enrolled children was 4.56 ± 1.08 months for the experimental group (n = 153) and 4.50 ± 1.04 months for the control group (n = 153). The comparative analysis of the variation in the progress between the two groups by independent t-test showed that, after the experimental intervention, the developmental quotient (DQ) of locomotor, personal-social, and language, as well as the general quotient (GQ) of the Griffiths Mental Development Scale-Chinese (GDS-C), the children in the experimental group demonstrated higher progress than those in the control group (P < 0.05). Furthermore, there was a significant decrease in the mean standard score of dysfunctional interaction, difficult children and the total level of parental stress in the term test for the experimental groups (P < 0.001 for all). CONCLUSIONS PIEIP intervention can significantly improve the developmental outcome and prognosis of children with GDD, especially in the areas of locomotor, personal-social, and language.

Abstract
Objective: To study the clinical and endoscopic features of mantle cell lymphoma (MCL). Methods: The clinical data and endoscopic characteristics of 20 patients with gastrointestinal MCL treated in the Affiliated Hospital of Zunyi Medical University and the Digestive Endoscopy Center of Guizhou Medical University from January 2011 to January 2021 were collected, and the histological and immunohistochemical characteristics of the tumor were observed. Meanwhile, 44 cases of non-gastrointestinal MCL in the above two hospitals in the same period were also enrolled. The clinical and endoscopic differences between the two groups were compared. Results: Among the 20 patients with gastrointestinal MCL, the male to female ratio was 4∶1 (16/4), the average age was (60.3±9.7) years, and 11 patients (55.0%, 11/20) were over 60 years old. The main clinical manifestations of 20 patients at the onset of the disease were bloody stool or black stool in 9 cases (45.0%), abdominal pain in 8 cases (40.0%). Moreover, 5.0% (1/20) had B symptoms (fever, night sweat and weight loss). The most frequently involved site was colorectum (50.0%). Endoscopic findings showed mucosal polypoid lesions in 13 cases (65.0%, 13/20), involving multiple intestinal segments, with polyp diameter of 0.2-3.5 cm. Two cases (10%) were in stage Ⅲ and 18 cases (90%) were in stage Ⅳ according to Ann Arbor staging. Seven cases (35.0%, 7/20) had the involvement of the peritoneal and retroperitoneal lymph nodes, 9 cases (45.0%, 9/20) had the involvement of the superficial lymph nodes in 45.0% (9/20), and 4 cases (20%, 4/20) had other extranodal invasion. Splenomegaly accounted for 35.0% (7/20). CD20, Bcl-2 and CD5 were positive or strongly positive in all gastrointestinal MCL tumor cells in 20 cases. Cyclin D1 was positive or strongly positive, accounting for 90.0% (18/20). The sex-determining region of Y chromosome-related high-mobility-group box 11 (SOX11) was positive or strongly positive, accounting for 65.0% (13/20). The positive index of Ki-67 was 5%-80%. Twenty cases (100%, 20/20) were followed up. The median follow-up was 41.2 months (1-74 months). There was no significant difference in the 3-year overall survival rate between the gastrointestinal MCL patients (70.0%) and non-gastrointestinal MCL patients (72.7%) (χ2=0.051, P=0.822). Conclusions: Abdominal discomfort is the main symptom of gastrointestinal MCL, which often occurs in the colorectum and often presents with multiple polypoid lesions. There are relatively few cases with B symptoms and extranodal invasion, and the prognosis is not different from that of patients with non-gastrointestinal MCL.

Abstract
Objective: To evaluate the relationship between lesion features of cytomegalovirus (CMV) retinitis, including lesion size and degree of opacity of lesion borders, and aqueous CMV-DNA load in patients after allogeneic hematopoietic stem cell transplantation. Methods: It was a retrospective case series study. Data of patients diagnosed as CMV retinitis after allogeneic hematopoietic stem cell transplantation at the Department of Ophthalmology, Peking University Third Hospital from January 2018 to October 2020 were reviewed. Lesion size was detected by ultra-wide-field fundus image and measured by ImageJ, an image processing and analysis software. Opacity of lesion borders was evaluated by a masked reader. The CMV retinitis lesions were divided into 3 types according to the opacity degree of the border of the lesions: suspected active lesion mildly to moderately opacified lesion and severely opacified lesion. All eyes were diagnosed as active cytomegalovirus retinitis. CMV-DNA in aqueous humor was detected at the first visit and at the end of the induction period of antiviral drugs. CMV-DNA load was quantitatively detected by polymerase chain reaction after 100 μl of aqueous humor was extracted, and were converted to common logarithmic representations. Pearson correlation analysis was used to analyze the correlation between lesion area, opacity degree of lesion border and aqueous humor CMV-DNA load. Results: A total of 71 eyes from 46 patients were included and 26 was male and 20 was female. The age of the patients was 27(13, 33)years. The active lesion size of CMV retinitis was 40(12, 65) disc areas. Eight eyes (11.3%) had a suspected active lesion, 51 eyes (71.8%) had a mildly to moderately opacified lesion border, and 12 eyes (16.9%) had a severely opacified border. At the first visit, 67 eyes (94.4%) were CMV-positive, and the CMV-DNA load was 2.04×104 (6.24× 102, 1.48 ×105) copies/ml. After 2 weeks of induction therapy, the viral load was 2.47×102 (1.08× 10, 6.87 ×103) copies/ml. The correlation analysis showed that the CMV-DNA load in aqueous humor was significantly correlated with the lesion border opacity both at presentation and 2 weeks after intravitreal antiviral treatment (r=0.765, P<0.001; r=0.761, P<0.001), but was not related with the size of active fundus lesions (r=0.209, P=0.095; r=0.220, P=0.078). Conclusion: Degrees of lesion border opacity can reflect levels of aqueous viral load of CMV retinitis in patients after allogeneic hematopoietic stem cell transplantation and can become a useful measurement for investigation of CMV retinitis activity.

Abstract
Objective: To discuss the application value of hard tissue section in the clinicopathology diagnosis. Methods: From March 2021 to December 2021, bone slices of 19 patients (1 patient with osteochondroma, 2 patients with chondrosarcoma, 4 patients with osteosarcoma, 2 patients with fibrous dysplasia, 2 patients with bone metastasis from thyroid papillary carcinoma, 2 patients with osteomyelitis, 4 patients with giant cell tumor of bone, 2 patients with Ewing sarcoma) and 16 hemopathy patients were collected from the Department of Pathology, Shanghai Sixth People's Hospital. Of the osteopathy patients, there were 14 male and 5 female with a median age of 31 (10-66) years. Meanwhile, there were 7 male and 9 female with a median age of 28 (16-65) years among these hemopathy patients. Thirty-five cases were treated with modified hard tissue slicing technique and paraffin embedding technique, respectively. The advantages and disadvantages of the two methods for clinical diagnosis of bone disease were compared by Hematoxylin-Eosin staining (H&E staining), immunohistochemical staining (IHC), fluorescence in situ hybridization (FISH) and Sanger sequencing. Results: The improved resin-embedded method showed better histological morphology and cell structure. Besides, the expression of Ki67, SATB2, CD34, SMA, CD68,MPO,CD4 and CD33 in immunohistochemical staining in bone tissues which were embedded in resin were more clear in the accurate positive localization than those using paraffin-embedded. MDM2 of FISH exhibited a higher fluorescence intensity and more accurate location. Meanwhile, both methods treated with Sanger sequencing met the requirements of DNA purity and mutation detection. Conclusion: The improved hard tissue section method is simple and short time-consuming, which is suitable for optimizing the clinical bone and bone marrow pathological diagnosis process.

Abstract
Background Breast cancer patients and their families are under various pressures in the process of disease diagnosis and treatment, which seriously threaten their physical and mental health. Findings from existing research suggest that good family resilience can help breast cancer families better adapt and cope with adversity and challenges. However, there are only a few intervention studies on family resilience and no intervention studies on resilience among the families of breast cancer patients. Therefore, this study aims to explore appropriate measures to improve the resilience level of breast cancer families and help them better cope with the disease. Objective The purpose of this study protocol is to demonstrate a coping-focused family resilience intervention to increase the level of resilience in the families of breast cancer patients and help them better cope with adversity. Methods The trial will recruit 80 breast cancer families and randomly assign them to experimental and control groups in a 1:1 ratio. The control group will receive routine care, and the intervention group will receive a 6-week one-on-one online family resilience intervention based on the control group. Two groups of subjects will be assessed at baseline and at 1 week, 1 month, and 3 months after the intervention. The primary outcome is family resilience, and the secondary outcomes are coping style, social support, family disease burden, and levels of anxiety and depression. Expected results We hypothesized that after the intervention, the intervention group would have significantly higher levels of family resilience than the preintervention and control groups. In the intervention group, other aspects related to family resilience, such as family disease burden and anxiety and depression levels of patients and their families, were significantly alleviated, and disease coping and social support levels were improved accordingly. Discussion If the program works, it can help breast cancer families identify family strengths and resources to proactively address challenges so that families can successfully navigate the crisis and patient and family recovery can be facilitated. It can also provide a practical path for clinical workers to help breast cancer families adjust rationally. Clinical Trial Registration This study has been registered in the Chinese Clinical Trials Registry (Registration Number: http://www.chictr.org.cn/ChiCTR2100052108).

Abstract
Purpose: The study aims to identify genetic variants in five Chinese families with Keratoconus (KC) and describe the characteristics of parental corneal topography. Methods: Fifteen participants, including five probands and ten parents from five Chinese families with KC, were recruited for genetic and clinical analyses. Targeted next-generation sequencing using a custom-designed panel for KC was applied on the probands for variant identification. Sanger sequencing and cosegregation analysis of the suspected pathogenic variants were performed on the family members. The pathogenicities of variants were evaluated according to the American College of Medical Genetics and Genomics guidelines (ACMG). Pentacam 3D anterior segment analysis system was applied for keratectasia detection and the Corvis ST for corneal biomechanics measurement. Fifteen parameters were recorded, including nine keratectasia indicators (BAD-D, TP, Kmax, Df, Db, Dp, Dt, Da, ARTH), six corneal biomechanical indicators (CBI, DA ratio, SP-A1, IR, bIOP, TBI). Results: A total of six novel variants, including five missense variants and one frameshift variant, were detected in the HMX1, SLC4A11, TGFBI, PIKFYVE, and ZEB1 genes in five probands, all of which showed co-segregation of genotype and clinical phenotype and were determined to be pathogenic. The genetic model was autosomal dominant (AD) in four families and autosomal recessive (AR) in 1 family. The analysis of keratectasia and corneal biomechanical indicators of the proband’s parents (first-generation relatives) in AD families revealed that there were several abnormal indexes in BAD-D, TP, Kmax, Df, Db, Dp, Dt, Da, CBI, DA ratio, SP-A1, IR, bIOP and TBI test indexes, showing clinical characteristics of incipient KC. Conclusion: Our study shows that variants in HMX1, SLC4A11, TGFBI, PIKFYVE, and ZEB1 were associated with KC. Our study extends the gene spectrum associated with KC, provides novel insights into KC phenotypic assessments, and contributes to early diagnosis for these patients.

Abstract
Background and Aims Non-alcoholic fatty liver disease (NAFLD) is a usual chronic liver disease and lacks non-invasive biomarkers for the clinical diagnosis and prognosis. Extracellular vesicles (EVs), a group of heterogeneous small membrane-bound vesicles, carry proteins and nucleic acids as promising biomarkers for clinical applications, but it has not been well explored on their lipid compositions related to NAFLD studies. Here, we investigate the lipid molecular function of urinary EVs and their potential as biomarkers for non-alcoholic steatohepatitis (NASH) detection. Methods This work includes 43 patients with non-alcoholic fatty liver (NAFL) and 40 patients with NASH. The EVs of urine were isolated and purified using the EXODUS method. The EV lipidomics was performed by LC-MS/MS. We then systematically compare the EV lipidomic profiles of NAFL and NASH patients and reveal the lipid signatures of NASH with the assistance of machine learning. Results By lipidomic profiling of urinary EVs, we identify 422 lipids mainly including sterol lipids, fatty acyl lipids, glycerides, glycerophospholipids, and sphingolipids. Via the machine learning and random forest modeling, we obtain a biomarker panel composed of 4 lipid molecules including FFA (18:0), LPC (22:6/0:0), FFA (18:1), and PI (16:0/18:1), that can distinguish NASH with an AUC of 92.3%. These lipid molecules are closely associated with the occurrence and development of NASH. Conclusion The lack of non-invasive means for diagnosing NASH causes increasing morbidity. We investigate the NAFLD biomarkers from the insights of urinary EVs, and systematically compare the EV lipidomic profiles of NAFL and NASH, which holds the promise to expand the current knowledge of disease pathogenesis and evaluate their role as non-invasive biomarkers for NASH diagnosis and progression.

Abstract
Apriona germari is one of the most serious wood-boring pests that cause damage to economic and landscaping trees and has adapted to a wide range of plants as diet. Gut bacteria play an important role in biology and ecology of herbivores, especially in growth and adaptation. To investigate how plant hosts shape A. germari gut microbiota, A. germari larvae were collected from Populus tomentosa and Malus pumilal, and gut microbiomes were sequenced based on 16S rDNA high-throughput sequencing technology. A total of 853,424 high-quality reads were obtained and clustered into 196 operational taxonomic units under a 97% similarity cutoff, which were annotated into 8 phyla, 10 classes, 21 orders, 34 families, 59 genera, and 39 species. Gibbsiella was the most dominant genus of intestinal bacteria, followed by Enterobacter and Acinetobacter. No significant difference was observed in larvae gut bacterial richness and diversity of A. germari collected from two hosts, though alpha diversity showed that the richness of gut bacteria in A. germari larvae collected on P. tomentosa was slightly higher than that in A. germari on M. pumilal, and beta diversity showed little difference between two host plants. The functional abundance analysis of the detected bacteria revealed fermentation, chemoheterotrophy, symbionts, and nitrate relative functions that highly possibly support wood-boring beetles to feed on woody tissues. Our study provided a theoretical basis for investigating the function of intestinal symbiosis bacteria of A. germari.

Abstract
OBJECTIVES No approved pharmacotherapies are available for patients with interstitial pneumonia with autoimmune features (IPAF). In the present work, we aimed to evaluate the efficacy and safety of pirfenidone for the treatment of IPAF. METHODS A retrospective cohort study consisting of patients who met diagnostic criteria for IPAF was performed after a multidisciplinary review, and the patients receiving pirfenidone were compared with those in the non-pirfenidone group. The baseline data and diagnostic characteristics of patients were assessed. Pulmonary function and prednisone dose were analysed by a mix-effects model. RESULTS A total of 184 patients, who met the diagnostic criteria of IPAF, were divided into two groups: pirfenidone group (n=81) and non-pirfenidone group (n=103). Patients in the pirfenidone group had a lower forced vital capacity (FVC%, p<0.001) and a lower diffusion capacity for carbon monoxide (DLCO%, p=0.003). The pirfenidone group exhibited a greater increase of FVC% at 6 (p=0.003), 12 (p=0.013), and 24 (p=0.003) months. After adjustment for sex, age, UIP pattern, baseline FVC% and DLCO%, patients in the pirfenidone group continued to show a greater improvement in FVC% (χ2(1)=4.59, p=0.032). Subgroup analysis identified superior therapeutic effects of pirfenidone in patients with dosage >600 mg/day (p=0.010) and medication course >12 months (p=0.007). Besides, the pirfenidone group had a lower prednisone dose than the non-pirfenidone group after 12 months of treatment (p=0.002). Moreover, 17 patients (19.32%) experienced side effects after taking pirfenidone, including one case of anaphylactic shock. CONCLUSIONS Pirfenidone (600-1,800 mg/day) might help improve FVC, with an acceptable safety and tolerability profile in IPAF patients.

Abstract
Species in the genus Paenibacillus from special habitats have attracted great attention due to their plant growth-promoting traits. A novel plant growth-promoting rhizobacteria (PGPR) species in the genus Paenibacillus was isolated from spruce forest at the height of 3,150 m in the Qilian Mountains, Gansu province, China. The phylogenetic analysis based on 16S rRNA, rpoB, and nifH gene sequences demonstrated that strain LC-T2T was affiliated in the genus Paenibacillus and exhibited the highest sequence similarity with Paenibacillus donghaensis KCTC 13049T (97.4%). Average nucleotide identity (ANIb and ANIm) and digital DNA–DNA hybridization (dDDH) between strain LC-T2T and P. donghaensis KCTC 13049T were 72.6, 83.3, and 21.2%, respectively, indicating their genetic differences at the species level. These differences were further verified by polar lipids profiles, major fatty acid contents, and several distinct physiological characteristics. Meanwhile, the draft genome analysis provided insight into the genetic features to support its plant-associated lifestyle and habitat adaptation. Subsequently, the effects of volatile organic compound (VOC) emitted from strain LC-T2T on the growth of Arabidopsis were evaluated. Application of strain LC-T2T significantly improved root surface area, root projection area, and root fork numbers by 158.3, 158.3, and 241.2%, respectively, compared to control. Also, the effects of LC-T2T on the growth of white clover (Trifolium repens L.) were further assessed by pot experiment. Application of LC-T2T also significantly improved the growth of white clover with root fresh weight increased over three-folds compared to control. Furthermore, the viable bacterial genera of rhizosphere soil were detected in each treatment. The number of genera from LC-T2T-inoculated rhizosphere soil was 1.7-fold higher than that of control, and some isolates were similar to strain LC-T2T, indicating that LC-T2T inoculation was effective in the rhizosphere soil of white clover. Overall, strain LC-T2T should be attributed to a novel PGPR species within the genus Paenibacillus based on phylogenetic relatedness, genotypic features, and phenotypic and inoculation experiment, for which the name Paenibacillus monticola sp. nov. is proposed.

Abstract
BACKGROUND Severe acute pancreatitis (SAP) is the most common gastrointestinal disease and is associated with unpredictable seizures and high mortality rates. Despite improvements in the treatment of acute pancreatitis, the timely and accurate diagnosis of SAP remains highly challenging. Previous research has shown that extracellular vesicles (EVs) in the plasma have significant potential for the diagnosis of SAP since the pancreas can release EVs that carry pathological information into the peripheral blood in the very early stages of the disease. However, we know very little about the metabolites of EVs that might play a role in the diagnosis of SAP. METHODS Here, we performed quantitative metabolomic analyses to investigate the metabolite profiles of EVs isolated from SAP plasma. We also determined the metabolic differences of EVs when compared between healthy controls, patients with SAP, and those with mild acute pancreatitis (MAP). RESULTS A total of 313 metabolites were detected, mainly including organic acids, amino acids, fatty acids, and bile acids. The results showed that the metabolic composition of EVs derived from SAP and MAP was significantly different from those derived from healthy controls and identified specific differences between EVs derived from patients with SAP and MAP. On this basis, we identified four biomarkers from plasma EVs for SAP detection, including eicosatrienoic acid (C20:3), thiamine triphosphate, 2-Acetylfuran, and cis-Citral. The area under the curve (AUC) was greater than 0.95 for both discovery (n = 30) and validation (n = 70) sets. CONCLUSIONS Our data indicate that metabolic profiling analysis of plasma EVs and the screening of potential biomarkers are of significant potential for improving the early diagnosis and severity differentiation of acute pancreatitis.

Abstract
Pulmonary fibrosis (PF) is a chronic and progressively fatal disease, but clinically available therapeutic drugs are limited due to efficacy and side effects. The possible mechanism of pulmonary fibrosis includes the damage of alveolar epithelial cells II (AEC2), and activation of immune cells such as macrophages. The ions released from bioceramics have shown the activity in stimulating soft tissue derived cells such as fibroblasts, endothelia cells and epithelia cells, and regulating macrophage polarization. Therefore, this study proposes an "ion therapy" approach based on the active ions of bioceramic materials, and investigates the therapeutic effect of bioactive ions derived from calcium silicate (CS) bioceramics on mouse models of pulmonary fibrosis. We demonstrate that silicate ions significantly reduce pulmonary fibrosis by simultaneously regulating the functions of AEC2 and macrophages. This result suggests potential clinical applications of ion therapy for lung fibrosis.

Abstract
INTRODUCTION Studies have shown nonlinear relationships between systolic blood pressure (SBP) and outcomes, with increased risk observed at both low and high blood pressure levels. However, the relationships between cumulative times at different SBP levels and outcomes in critically ill patients remain unclear. We hypothesized that an appropriate SBP level is associated with a decrease in adverse outcomes after intensive care unit (ICU) admission. METHODS This study was a retrospective analysis of data from the Medical Information Mart for Intensive Care (MIMIC) III database, which includes more than 1,000,000 SBP records from 12,820 patients. Associations of cumulative times at four SBP ranges (<100 mm Hg, 100-120 mm Hg, 120-140 mm Hg, and ≥140 mm Hg) with mortality (12-, 3-, 1-month mortality and in-hospital mortality) were evaluated. Restricted cubic splines and multivariable Cox regression models were employed to assess associations between mortality and cumulative times at SBP levels (4 levels: <2, 2-12, 12-36, and ≥36 h) over 72 h of ICU admission. Additionally, 120 mm Hg to 140 mm Hg was subdivided into <12 h (Group L) and ≥12 h (Group M) subsets and subjected to propensity-score matching and subgroup analyses. RESULTS At 120 mm Hg to 140 mm Hg, level-4 SBP was associated with lower adjusted risks of mortality at 12 months (OR, 0.71; CI, 0.61-0.81), 3 months (OR, 0.72; CI, 0.61-0.85), and 1 month (OR, 0.61; CI, 0.48-0.79) and in the hospital (OR, 0.71; CI, 0.58-0.88) than level-1 SBP. The cumulative times at the other 3 SBP ranges (<100 mm Hg, 100-120 mm Hg, and ≥140 mm Hg) were not independent risk predictors of prognosis. Furthermore, Group M had lower 12-month mortality than Group L, which remained in the propensity-score matched and subgroup analyses. CONCLUSIONS SBP at 120 mm Hg to 140 mm Hg was associated with decreased adverse outcomes. Randomized trials are required to determine whether the outcomes in critically ill patients improve with early maintenance of a SBP level at 120 mm Hg to 140 mm Hg.

Abstract
Objective: To investigate the effect of high-fat diet (HFD) on respiratory function and its mitochondrial mechanism in mice. Methods: Twenty 4-week-old healthy male C57BL/6 mice were divided by simple random grouping into two groups, 10 mice for each group. Mice were raised with normal diet (NFD) and HFD for 16 weeks, respectively, and weighed once every two weeks. At the end of the intervention, respiratory parameters were measured by whole-body plethysomography, serum and diaphragm tissue lipid species were measured, diaphragm tissue was stained to observe diaphragmmatic morphology, muscle fiber phenotype and mitochondrial ultrastructure. Real-time fluorescence quantitative PCR and immunoblotting were used to detect myosin heavy chain(MHC) and mitochondrial dynamics-related genes and protein expression. Results: The baseline body weights of NFD and HFD mice were (19.17±0.59) and (19.12±0.64) g, respectively, with no statistically significant differences (P=0.857). After 16 weeks of feeding, the body weight of mice in the HFD group was (41.28±2.21) g, which was higher than NFD group [(27.14±0.53) g, P<0.001]. The peak inspiratory flow rate, tidal volume and minute ventilation of mice in the HFD group were (5.72±0.64) ml/s, (0.23±0.04) ml and (97.49±21.68) ml, respectively, which were lower than NFD group [(7.70±1.52) ml/s, (0.31±0.07) ml and (129.99±28.87) ml, respectively, all P values<0.05]. Penh value was 1.16±0.07, which was higher than NFD group (0.98±0.09, P<0.001). The diaphragmatic triglyceride content of mice in the HFD group was (20.43±6.36) mmol/mg, which was higher than NFD group [(11.62±1.78) mmol/mg] (P=0.003), and lipid droplets were deposited in the diaphragm fibers. The percentage of MHC-Ⅰ muscle fibers in the diaphragm of mice in the HFD group was 13.33%±2.95%, which was lower than NFD group (19.20%±1.23%, P=0.034). The mitochondria of the diaphragm in the NFD group were arranged in rows with clear structures, while in the HFD group showed swelling, cristae breakage and vacuoles. The relative expression level of mitochondrial fusion protein 2 in the diaphragm of the HFD group was 0.61±0.16, which was lower than NFD group (1.28±0.03, P<0.001); the relative expression of mitochondrial dynamin-related protein 1 were 1.18±0.06 and 0.91±0.11, respectively, both higher than NFD group (0.61±0.07 and 0.60±0.04, respectively, P<0.001). Conclusion: HFD impairs respiratory function in mice by the mechanism associated with the MHC-Ⅰ muscle fibers decrease and the mitochondrial dynamics imbalance of diaphragm.

Abstract
A Gram-negative aerobic bacterium, strain M30-35 T, was isolated from the rhizosphere of Haloxylon ammodendron in Tengger desert, Gansu province, northwest China. Our previous research indicated that strain M30-35 T can promote the growth of ryegrass (Lolium perenne L.). In this study, strain M30-35 T was subjected to a polyphasic taxonomic study. Phylogenetic analysis of the 16S rRNA gene and two other housekeeping genes (gyrB, rpoD) showed that strain M30-35 T is a member of Pseudomonas anguilliseptica group. The average nucleotide identity (ANI) scores for strains KMM 3042 T and FR1439T were 76.5% and 83.7%, respectively, and DNA-DNA hybridization (DDH) were 21.6% and 26.6%, respectively, and the rates were less than the threshold range for species determination. The dominant cellular fatty acids of strain M30-35 T were C16:0 (22.7%), summed feature 3 (C16:1ω7c and/or C16:1ω6c; 18.5%), summed feature 8 (C18:1ω7c and/or C18:1ω6c; 23.1%). The major polar lipids were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, phospholipid and aminophospholipid and the predominant respiratory quinone was ubiquinone (Q9). On the basis of above data, it can be concluded that strain M30-35 T represents a novel species in the genus Pseudomonas, for which the name Pseudomonas rhizovicinus sp. nov. is proposed. The type strain is M30-35 T (= MCCC 1K03247T = KCTC 52664 T).

Abstract
Glucocorticoid (GC) hormone has been commonly used to treat systemic inflammation and immune disorders. However, the side effects associated with long-term use of high-dose GC hormone limit its clinical application seriously. GC hormone that can specifically target the lung might decrease the effective dosage and thus reduce GC-associated side effects. In this study, we successfully prepared human lung-targeting liposomal methylprednisolone crosslinked with nanobody (MPS-NSSLs-SPANb). Our findings indicate that MPS-NSSLs-SPANb may reduce the effective therapeutic dosage of MPS, achieve better efficacy, and reduce GC-associated side effects. In addition, MPS-NSSLs-SPANb showed higher efficacy and lower toxicity than conventional MPS.

Abstract
BACKGROUND Pulmonary cryptococcosis (PC) is an infection typically diagnosed in immunocompromised or immunocompetent patients, which can lead to severe disease if not treated appropriately. We aimed to determine the association between clinical manifestations, computed tomography (CT) findings, and host immune status with the serum cryptococcal antigen (CRAG) test results of PC patients. METHODS The clinical data of 378 PC patients over a 12-year period were retrospectively reviewed at Shanghai Pulmonary Hospital (Shanghai, China). Serum CRAG was detected by a latex agglutination (LA) test using CryptoTrol (Immuno-Mycologics Inc., Norman, OK, USA). Patients were categorized according to their serum LA results, and their clinical characteristics were analyzed: 244 of 378 patients showed positive serum LA results and 134 had negative results. RESULTS Immunocompromised hosts (ICH) were more likely to present positive LA results. The ICH group had higher titers of LA test than the non-immunocompromised host (NICH) group. Patients with negative LA results often had no symptoms and their CT findings presented a solitary nodule or mass, while LA-positive patients had variable symptoms such as cough, expectoration, fever, etc. A large diversity of CT manifestations were observed in the LA-positive patients, such as multiple nodules, patchy shadows, interstitial infiltrates, and diffuse granular shadows. Patients with a solitary nodule or mass had lower titers than did the patients with other manifestations. The clinical characteristics of LA-positive patients were different from those of LA-negative patients. CONCLUSIONS Serum CRAG test results were found to be associated with the clinical manifestations, CT findings, and host immune status of PC patients.

Abstract
Introduction Opioids are potent painkillers but can have severe adverse effects in the intensive care unit (ICU). The aim of this study was to compare the outcomes of fentanyl and morphine use among patients at risk for and with acute respiratory distress syndrome (ARDS). Methods We developed a dataset of real-world data to enable the comparison of the effectiveness and safety of opioids and the associated outcomes from the Multiparameter Intelligent Monitoring in Intensive Care (MIMIC)-III database and the eICU Collaborative Research Database. Patients who were admitted to the ICU with a diagnosis of or at risk for ARDS and received mechanical ventilation for at least 12 h were included. Patients were enrolled sequentially into one of six groups in three cohorts: treated with fentanyl or not; treated with morphine or not; and treated with fentanyl or morphine. Propensity score matching and multivariable analyses were performed. Results Fentanyl was associated with higher in-hospital mortality in the propensity score-matched model but not in the linear regression model. The use of morphine was associated with a higher in-hospital mortality in both models. Both fentanyl and morphine were associated with longer duration of mechanical ventilation, ICU stay, and hospitalization and a decreased likelihood of being discharged home in both models. Notably, compared with morphine, fentanyl was associated with a lower mortality and an increased likelihood of being discharged home. Conclusions Both fentanyl and morphine were independent risk factors for worse outcomes in patients with or at risk for ARDS. Compared with morphine, fentanyl may be preferred in these patients.

Abstract
PURPOSE This study aimed to examine the impact of family resilience on the individual resilience of couples during cancer and explore the potential mediating role of perceived social support and the moderating role of sex in this association in cancer patient-spouse dyads. METHOD The participants were 272 cancer patients and their spouses (N = 544) who completed the Family Resilience Assessment Scale, the Perceived Social Support Scale and the Resilience Scale. We adopted the actor-partner interdependence mediation model to examine whether and how patients' and their spouses' family resilience was associated with their own and their partners' perceived social support and individual resilience. RESULTS The results indicated that the patients' and their spouses' level of family resilience was positively associated with their own individual resilience directly and indirectly by increasing their own perceived social support. The family resilience of the spouses was associated with an increase in the patients' individual resilience only indirectly by increasing the patients' perceived social support. The spouse-actor effects between family resilience and individual resilience differed significantly by sex. CONCLUSION Enhancing family resilience and perceived social support within the family can improve individual resilience. The findings regarding the sex differences serve as a rationale for gender-based approaches to improving individual resilience in the family context.

Abstract
Background: Sedatives are commonly used in patients with or at risk for acute respiratory distress syndrome (ARDS) during mechanical ventilation. To systematically compare the outcomes of sedation with midazolam, propofol, and dexmedetomidine in patients with or at risk for ARDS. Methods: We developed a dataset of real-world data to enable the comparison of the effectiveness and safety of sedatives and the associated outcomes from the MIMIC-III database and the eICU Collaborative Research database. We performed a systematic study with six cohorts to estimate the relative risks of outcomes among patients administered different sedatives. Propensity score matching was performed to generate a balanced 1:1 matched cohort and to identify potential prognostic factors. The outcomes included hospital mortality, duration of mechanical ventilation, length of intensive care unit stay, length of hospitalization, and likelihood of being discharged home. Results: We performed 60 calibrated analyses among all groups and outcomes with 17,410 eligible patients. Sedation with dexmedetomidine was associated with a lower in-hospital mortality rate than sedation with midazolam and propofol or sedation without dexmedetomidine (p < 0.001). When compared with no sedation, the use of midazolam, propofol or dexmedetomidine was associated with a longer ICU stay and longer hospitalization duration (p < 0.01). Patients treated with midazolam were relatively less likely to be discharged home (p < 0.05). Conclusion: Patients treated with dexmedetomidine had a reduced risk of mortality. These data suggest that dexmedetomidine may be the preferred sedative in patients with or at risk for ARDS.

Abstract
PURPOSE This pilot study aimed to evaluate the feasibility and effect of a guided self-disclosure intervention (GSDI) promoting benefit finding (BF) for breast cancer patients. METHODS A total of 40 women with breast cancer were randomized either to a GSDI group, which included a 6-session face-to-face self-disclosure intervention, or to a control group. The Benefit Finding Scale (BFS) was used to measure BF, the Distress Disclosure Index (DDI) was used to measure self-disclosure, and the Impact of Event Scale-Revised (IES-R) was used to measure cognitive reappraisal. The outcomes were evaluated at baseline and the 3rd and 6th months. RESULTS The GSDI group had more satisfaction (t = 2.35, P = .02) than the control group and had significant group effects of higher BF (t = 2.214, P = .03) and a lower avoidance of the IES-R (t = -2.353, P = .024) at the 3rd month. There was a significant difference of BF (t = 2.036, P = .049) between the two groups at the 6th month, and other outcomes were not significant (P > .05). Intention-to treat (ITT) analysis showed significant time effects for all outcomes (P < .05); there were slightly significant time × group effects for BF (F = 4.15, P = .052) and disclosure (F = 2.719, P = .090). There were no time × group effects for the other outcomes (all P > .05). CONCLUSION This study suggests that the GSDI intervention may be feasible in the clinic and might improve BF for breast cancer patients. However, future research needs to further refine the intervention and expand the sample to carry out a full-scale randomized controlled trial.

Abstract
Background The role of peripheral blood lymphocyte (pBL) in breast cancer has long been studied. However, the predictive role of pBL in advanced breast cancer (ABC) is poorly understood. Methods A total of 303 patients with ABC were consecutively recruited at our center between January 2015 and September 2019. At baseline, pBL subtypes were detected in all patients with 229 blood samples available for circulating tumor DNA (ctDNA) detection. pBL was analyzed through flow cytometry. ctDNA-based gene mutations were detected using next generation sequencing. The cutoff value of pCTL was estimated by X-tile software. Progression free survival (PFS) was estimated by Kaplan-Meier curve and Cox hazard proportion regression model, with difference detection by log-rank test. Results Median follow-up time of the study was 21.0 months. The median age of diagnosis was 52.0 years. Among the pBL subtypes, only pCTL level was found predictive for PFS in the HER2+ patients whom received anti-HER2 therapy (13.1 vs. 5.6 months, P = 0.001). However, the predictive role of pCTL was not found in HR-positive (P = 0.716) and TNBC (P = 0.202). pCTL high associated with suppressive immune indictors including lower CD4/CD8 ratio (P = 0.004) and high level of Treg cell (P = 0.004). High occurrence of FGFR1 amplification which has been reported as immune suppressor was also found in HER2+ patients with pCTL high (22.2% vs. 4.3%, P = 0.048). Conclusions Higher pCTLs level associated with shorter PFS and FGFR1 mutation in HER2+ ABC patients. High pCTL level predicts shorter first-line PFS in HER2+ patients receiving anti-HER2 based regimens. The predictive role of pCTL level found in HER2+ patients was not applicable in HR+ and TNBC patients. High level of pCTL was associated with immunosuppressive status and FGFR1 mutations in HER2+ breast cancer patients.

Abstract
Cisplatin (cis-Dichlorodiammine platinum, CP), as the first-line chemotherapy drug of choice for many cancers such as urogenital system tumors and digestive tract tumors, also causes toxicity and side effects to the kidney. Previous studies have shown that Pulsatilla chinensis has significant anti-inflammatory and antioxidant activities, but the mechanism of cisplatin induced acute kidney injury (AKI) in vivo has not been thoroughly studied. The purpose of this study is to investigate the protective effect of pulchinenoside B4 (PB4), a representative and major component with a content of up to 10% in root of P. chinensis, on AKI induced by CP in mice. Our results indicated the significant protective effect of PB4 by evaluating renal function indicators, inflammatory factor levels and renal histopathological changes. In addition, PB4 may mainly act on NF-κB signaling pathway to reduce the levels of tumor necrosis factor-alpha (TNF-α), interleukin-1 beta (IL-1β), cyclooxygenase-2 (COX-2), and inducible nitric oxide synthase (iNOS) in the kidney after CP exposure, thus exerting anti-inflammatory activity. Furthermore, PB4 regulated MAPK signaling pathway and its downstream apoptotic factors to inhibit the occurrence of apoptosis, such as Bax, Bcl-2, caspase 3 and caspase 9. Notably, the activations of caspase 3 induced by cisplatin were strikingly reduced in PB4-treated mice. Therefore, the above evidence suggested that PB4 is a potential renal protectant with significant anti-inflammatory and anti-apoptotic effects.

Abstract
Background: More than 30% of estrogen receptor-positive breast cancers are resistant to primary
hormone therapy, and about 40% that initially respond to hormone therapy eventually
acquire resistance. Although the mechanisms of hormone therapy resistance remain
unclear, aberrant DNA methylation has been implicated in oncogenesis and drug
resistance. Purpose: We investigated the relationship between methylome variations in circulating tumor DNA
and exemestane resistance, to track hormone therapy efficacy. Methods: We prospectively recruited 16 patients who were receiving first-line therapy in our
center. All patients received exemestane-based hormone therapy after enrollment. We
collected blood samples at baseline, first follow-up (after 2 therapeutic cycles) and at
detection of disease progression. Disease that progressed within 6 months under
exemestane treatment was considered exemestane resistance but was considered relatively
exemestane-sensitive otherwise. We obtained circulating tumor DNA-derived methylomes
using the whole-genome bisulfide sequencing method. Methylation calling was done by
BISMARK software; differentially methylated regions for exemestane resistance were
calculated afterward. Results: Median follow-up for the 16 patients was 19.0 months. We found 7 exemestane
resistance-related differentially methylated regions, located in different chromosomes,
with both significantly different methylation density and methylation ratio. Baseline
methylation density and methylation ratio of chromosome 6 [32400000-32599999] were both
high in exemestane resistance. High baseline methylation ratios of chromosome 3
[67800000-67999999] (P = .013), chromosome 3 [140200000-140399999]
(P = .037), and chromosome 12 [101200000-101399999]
(P = .026) could also predict exemestane resistance. During
exemestane treatment, synchronized changes in methylation density and methylation ratio
in chromosome 6 [32400000-32599999] could accurately stratify patients in terms of
progression-free survival (P = .000033). Cutoff values of methylation
density and methylation ratio for chromosome 6 [149600000-149799999] were 0.066 and
0.076, respectively. Conclusion: Methylation change in chromosome 6 [149600000-149799999] is an ideal predictor of
exemestane resistance with great clinical potential.

Abstract
It is currently not understood whether cigarette smoke exposure facilitates sensitisation to self-antigens and whether ensuing auto-reactive T cells drive chronic obstructive pulmonary disease (COPD)-associated pathologies.To address this question, mice were exposed to cigarette smoke for 2 weeks. Following a 2-week period of rest, mice were challenged intratracheally with elastin for 3 days or 1 month. Rag1-/- , Mmp12-/- , and Il17a-/- mice and neutralising antibodies against active elastin fragments were used for mechanistic investigations. Human GVAPGVGVAPGV/HLA-A*02:01 tetramer was synthesised to assess the presence of elastin-specific T cells in patients with COPD.We observed that 2 weeks of cigarette smoke exposure induced an elastin-specific T cell response that led to neutrophilic airway inflammation and mucus hyperproduction following elastin recall challenge. Repeated elastin challenge for 1 month resulted in airway remodelling, lung function decline and airspace enlargement. Elastin-specific T cell recall responses were dose dependent and memory lasted for over 6 months. Adoptive T cell transfer and studies in T cells deficient Rag1-/- mice conclusively implicated T cells in these processes. Mechanistically, cigarette smoke exposure-induced elastin-specific T cell responses were matrix metalloproteinase (MMP)12-dependent, while the ensuing immune inflammatory processes were interleukin 17A-driven. Anti-elastin antibodies and T cells specific for elastin peptides were increased in patients with COPD.These data demonstrate that MMP12-generated elastin fragments serve as a self-antigen and drive the cigarette smoke-induced autoimmune processes in mice that result in a bronchitis-like phenotype and airspace enlargement. The study provides proof of concept of cigarette smoke-induced autoimmune processes and may serve as a novel mouse model of COPD.

Abstract
Cisplatin, a proven effective chemotherapeutic agent, has been used clinically to treat malignant solid tumors, whereas its clinical use is limited by serious side effect including nephrotoxicity. Platycodin D (PD), the major and marked saponin isolated from Platycodon grandiflorum, possesses many pharmacological effects. In this study, we evaluated its protective effect against cisplatin-induced human embryonic kidney 293 (HEK-293) cells injury and elucidated the related mechanisms. Our results showed that PD (0.25, 0.5, and 1 μM) can dose-dependently alleviate oxidative stress by decreasing malondialdehyde and reactive oxygen species, while increasing the levels of glutathione, superoxide dismutase, and catalase. Moreover, the elevation of apoptosis including Bax, Bad, cleaved caspase-3,-9, and decreased protein levels of Bcl-2, Bcl-XL induced by cisplatin were reversed after PD treatment. Importantly, PD pretreatment can also regulate PI3K/Akt and ERK/JNK/p38 signaling pathways. Furthermore, PD was found to reduce NF-κB-mediated inflammatory relative proteins. Our finding indicated that PD exerted significant effects on cisplatin induced oxidative stress, apoptosis and inflammatory, which will provide evidence for the development of PD to attenuate cisplatin-induced nephrotoxicity.

Abstract
OBJECTIVE To evaluate recovering consciousness effect of electroacupuncture (EA) on patients after traumatic brain injury (TBI) surgery. METHODS A total of 100 patients with traumatic coma were randomly divided into an observation group and a control group, 50 cases in each group. The control group was mainly treated with awakening drugs and neurotrophic drugs; on the basis of treatment in the control group, the observation group was treated with EA at Neiguan (PC 6) and Shuigou (GV 26) with disperse-dense wave, 2 Hz/100 Hz in frequency, 0.1-5 mA in intensity. After 30 min of EA, the needles were stayed 60 min. The treatment was performed once a day for 14 consecutive days. The changes in Glasgow coma score (GCS) was observed in the two groups before treatment and after 7, 14 days of treatment; and the two groups were followed up for 3 months after treatment to evaluate the Glasgow outcome scale (GOS) and Barthel index (BI) scores. RESULTS After 7, 14 days of treatment, the GCS scores of the two groups were higher than those before treatment (P<0.05), and the increase degree in the observation group was significantly larger than that in the control group (P<0.05). At 3 months of follow-up, the GOS and BI scores of the observation group were better than those of the control group (P<0.05). CONCLUSION Early electroacupuncture intervention can effectively promote the recovery of consciousness after traumatic brain injury surgery, and has a curative long-term effect.

Abstract
AIM To identify mutations with whole exome sequencing (WES) in a Chinese X-linked retinitis pigmentosa (XLRP) family. METHODS Patients received the comprehensive ophthalmic evaluation. Genomic DNA was extracted from peripheral blood and subjected to SureSelect Human All Exon 6+ UTR exon capture kit. The exons were sequenced as 100 base paired reads on Illumina HiSeq2500 system. Only mutations that resulted in a change in amino acid sequence were selected. A pattern of inheritance of the RP family was aligned to identified causal mutation. RESULTS We analysed the data of WES information from XLRP family. The analysis revealed a hemizygous large genomic deletion of RPGR c.29_113del was responsible for this XLRP. The gross deletion lead to a frame-shift mutation and generate stop codon at 7 animo acid behind Asp (D10Afs*7), which would serious truncate RPGR protein. The novel frame-shift mutation was found to segregate with retinitis pigmentosa (RP) phenotype in this family. Bilateral myopia was present on the male patients, but carrier female showed unilateral myopia without RP. CONCLUSION Our study identifies a novel frame-shift mutation of RPGR in a Chinese family, which would expand the spectrum of RPGR mutations. The geno-phenotypic analysis reveals a correlation between RP and myopia. Although exact mechanism of RP related myopia is still unknown, but the novel frame-shift mutation will give our hit on studying the molecular pathogenesis of RP and myopia.

Chemical fertilizers can supply essential nutrients to crops increasing their yield, however, they can also cause serious environmental problems. Biofertilizer has received more and more attention because of its environmentally friendly and pollution-free characteristics. Haloxylon ammodendron, a desert succulent shrub, has become an important plant species for vegetation restoration in several deserts in China because of its strong drought tolerance. Its extensive root systems and unique rhizosphere bacterial community aid H. ammodendron adapt to this extreme environment. In this study, Bacillus sp. WM13-24 and Pseudomonas sp. M30-35 isolated from the rhizosphere of H. ammodendron in our previous study and Bacillus amyloliquefaciens GB03 and Sinorhizobium meliloti ACCC17578 as well-studied beneficial strains were used to prepare two types of biofertilizer, WM13-24 biofertilizer containing Bacillus sp. WM13-24 and integrated biofertilizer containing all the four strains. Results presented here showed that WM13-24 biofertilizer and the integrated biofertilizer improved chili plant growth, fruit yield and quality and the rhizosphere soil nitrogen content, enzyme activities, and the quantity and biodiversity of viable bacteria. Compared to the control, WM13-24 biofertilizer and a commercial biofertilizer, the integrated biofertilizer performed best in significantly increasing plant height, stem diameter, leaf length and width, chlorophyll content, fruit yield, soluble sugar content, ascorbic acid content, organic acid content, soil urease activity, catalase activity and the quantity and biodiversity of viable bacteria. This study provided a theoretical and practical basis for large scale development of integrated biofertilizers using beneficial rhizobacterial strains from the desert plant rhizosphere.

Abstract
Aberrant expression of protein arginine methyltransferases (PRMTs) has been implicated in a number of cancers, making PRMTs potential therapeutic targets. But it remains not well understood how PRMTs impact specific oncogenic pathways. We previously identified PRMTs as important regulators of cell growth in neuroblastoma, a deadly childhood tumor of the sympathetic nervous system. Here, we demonstrate a critical role for PRMT1 in neuroblastoma cell survival. PRMT1 depletion decreased the ability of murine neuroblastoma sphere cells to grow and form spheres, and suppressed proliferation and induced apoptosis of human neuroblastoma cells. Mechanistic studies reveal the prosurvival factor, activating transcription factor 5 (ATF5) as a downstream effector of PRMT1-mediated survival signaling. Furthermore, a diamidine class of PRMT1 inhibitors exhibited anti-neuroblastoma efficacy both in vitro and in vivo. Importantly, overexpression of ATF5 rescued cell apoptosis triggered by PRMT1 inhibition genetically or pharmacologically. Taken together, our findings shed new insights into PRMT1 signaling pathway, and provide evidence for PRMT1 as an actionable therapeutic target in neuroblastoma.

Abstract
China is implementing an extensive urban forestry plan in Xiongan New Area (XNA), a new city in Hebei province. The city has been designated to serve Beijing’s noncapital functions and promote the integration of the broader Beijing–Tianjin–Hebei city-region. As part of a green initiative to minimize environmental impacts and its carbon footprint, a massive urban forestry system has been planned on an unprecedented scale, expected to cover over 600 km2 by 2030. Using science to inform policy, one major goal is to simultaneously minimize impacts of invasive species, while making urban forests more resilient to potential invasive species threats. In this review, we introduce these urban forestry plans such as basic concepts and principles for afforestation, tree species to be planted, delineation of existing pests already established, and expected forest invasive species of concern threatening the new area. Finally, we introduce a framework for invasive pest management strategies in XNA based on a “big data” approach and decision system to minimize impacts of invasive species. This new approach to urban forestry has the potential to become an exemplary global model for urban forestry planning, one that integrates research activities focused on forest health surveys and monitoring with sustainable forestry management. Finally, we provide an overview of the forest health policy required for the design of an unprecedentedly large new urban forest from initial planning to full implementation of an integrated forest management program.

Abstract
AIM This study aimed to examine the relationship between optimism, core self-evaluations, positive coping strategies, and job satisfaction for Chinese specialist nurses. METHODS A cross-sectional design was used. Two hundred and seventy-eight Chinese specialist nurses answered the Chinese Minnesota Satisfaction Questionnaire, the Chinese Revised Life Orientation Test, the Chinese Core Self-Evaluations Scale, and the Chinese Simplified Coping Style Scale. Descriptive analysis, independent-sample T-tests, one-way analysis of variance, Pearson correlation analyses, and bootstrap method were conducted to analyze data. RESULTS Total effect (c = 0.860, SE = 0.143, 95% CI 0.579-1.142) of optimism on job satisfaction was significant. The path through single mediation of core self-evaluations (point estimate = 0.165; 95% CI 0.041-0.318), the path through the single mediation of positive coping (point estimate = 0.124; 95% CI 0.042-0.254), and the path through both mediators (point estimate = 0.033; 95% CI 0.005-0.085) were all statistically significant. The total indirect effect was also statistically significant (point estimate = 0.322; 95% CI 0.151-0.535). CONCLUSIONS This study concluded that optimism was first sequentially associated with core self-evaluations and then associated with positive coping strategies, which was in turn related to job satisfaction of Chinese specialist nurses. Clinical nursing administrators should take measures that focus on improving specialist nurse job satisfaction to further improve their retention rates.

Abstract
Pulmonary fibrosis is a progressive fibrotic lung disease with a paucity of therapeutic options. Here we investigated the potential roles of probucol, a cholesterol-lowering drug with potent anti-oxidation properties, on pulmonary epithelial-mesenchymal transition (EMT) and fibrosis. We found that bleomycin-induced lung fibrosis was associated with increased transforming growth factor (TGF)-β1, α-smooth muscle actin (α-SMA) and decreased E-cadherin expression in lung tissues, indicating EMT formation. Bleomycin treatment resulted in an induction of oxidative stress in lung tissues. Probucol treatment attenuated bleomycin-induced TGF-β1 production, EMT and pulmonary fibrosis, meanwhile it suppressed bleomycin-induced oxidative stress. Bleomycin treatment resulted in decreases in protein expressions of Sirtuin 3 (SIRT3) in the lung, which were restored by ROS scavenger NAC and probucol treatment, suggesting that probucol might restore SIRT3 expression by suppressing bleomycin-induced oxidative stress. In the mouse alveolar type II epithelial cell line MLE-12, probucol treatment leads to an increase in SIRT3 expression in bleomycin-treated AT-II cells, which might contribute to the inhibitory effect of probucol on EMT through suppressing hypoxia inducible factor (HIF)-1α/TGF-β1 pathway. In addition, probucol inhibited bleomycin-induced macrophage infiltration in the lung. Bleomycin decreased SIRT3 protein expression, whereas increased HIF-1α activation and TGF-β1 release in the mouse macrophage cell line RAW264.7, which were attenuated by probucol treatment. Taken together, the present study suggests that probucol may ameliorate EMT and lung fibrosis through restoration of SIRT3 expression. The data obtained in this study provides proof for the idea that probucol may be a potential therapeutic option for the treatment of pulmonary fibrosis.
