Abstract
The incidence of urothelial carcinoma continues to rise annually, particularly among the elderly. Prompt diagnosis and treatment can significantly enhance patient survival and quality of life. Urine cytology remains a widely-used early screening method for urothelial carcinoma, but it still has limitations including sensitivity, labor-intensive procedures, and elevated cost. In recent developments, microfluidic chip technology offers an effective and efficient approach for clinical urine specimen analysis. Digital holographic microscopy, a form of quantitative phase imaging technology, captures extensive data on the refractive index and thickness of cells. The combination of microfluidic chips and digital holographic microscopy facilitates high-throughput imaging of live cells without staining. In this study, digital holographic flow cytometry was employed to rapidly capture images of diverse cell types present in urine and to reconstruct high-precision quantitative phase images for each cell type. Then, various machine learning algorithms and deep learning models were applied to categorize these cell images, and remarkable accuracy in cancer cell identification was achieved. This research suggests that the integration of digital holographic flow cytometry with artificial intelligence algorithms offers a promising, precise, and convenient approach for early screening of urothelial carcinoma.

Abstract
Nowadays, label-free imaging flow cytometry at the single-cell level is considered the stepforward lab-on-a-chip technology to address challenges in clinical diagnostics, biology, life sciences and healthcare. In this framework, digital holography in microscopy promises to be a powerful imaging modality thanks to its multi-refocusing and label-free quantitative phase imaging capabilities, along with the encoding of the highest information content within the imaged samples. Moreover, the recent achievements of new data analysis tools for cell classification based on deep/machine learning, combined with holographic imaging, are urging these systems toward the effective implementation of point of care devices. However, the generalization capabilities of learning-based models may be limited from biases caused by data obtained from other holographic imaging settings and/or different processing approaches. In this paper, we propose a combination of a Mask R-CNN to detect the cells, a convolutional auto-encoder, used to the image feature extraction and operating on unlabelled data, thus overcoming the bias due to data coming from different experimental settings, and a feedforward neural network for single cell classification, that operates on the above extracted features. We demonstrate the proposed approach in the challenging classification task related to the identification of drug-resistant endometrial cancer cells.

Abstract
BACKGROUND Cyclin B2 (CCNB2), a member of the cyclin family, is an oncogene in multiple cancers, including nasopharyngeal carcinoma (NPC). However, the epigenetics mechanism for CCNB2 overexpression in NPC remains unclear. This study dissects the regulatory role of CCNB2 in NPC and the molecular mechanism. METHODS Differentially methylated genes (DMG) and differentially expressed genes (DEG) were screened out in GSE52068 and GSE13597 databases, respectively, and candidate targets were identified by the Venn diagram. GO annotation and pathway enrichment analyses were performed on selected DMG and DEG, and a PPI network was constructed to pinpoint hub genes. PCR and qMSP were conducted to detect the expression and methylation of CCNB2 in cells. The siRNA targeting CCNB2 was transfected into NPC cells, and the migration, proliferation, cell cycle, epithelial-mesenchymal transition (EMT), tumorigenesis, and metastasis were examined. The upstream factor responsible for CCNB2 overexpression in NPC was explored. The p53 activity in NPC cells was assessed using western blot analysis. RESULTS CCNB2 showed hypomethylation and overexpression in NPC. CCNB2 silencing inhibited cell migration, proliferation, cell cycle entry, and EMT. JMJD6 was overexpressed in NPC and upregulated CCNB2 through demethylation. JMJD6 reversed the effects of CCNB2 downregulation, resulting in elevated cellular activity in vitro and tumorigenic and metastatic activities in vivo. CCNB2 blocked the p53 pathway, while the p53 pathway inhibitor reversed the effect of CCNB2 silencing to increase the activity of NPC cells. CONCLUSIONS JMJD6 enhanced CCNB2 transcription by demethylating CCNB2, thereby repressing the p53 pathway and promoting NPC progression.

Abstract
Introduction: The morphological characteristics of the endometrium in patients with choriocarcinoma have not been well described. We described the endometrial morphology patterns in 46 choriocarcinomas and analyzed their relationship with the clinicopathological characteristics of these patients. Methods: Forty-six patients diagnosed with choriocarcinoma that had sufficient endometrial tissues for histopathological diagnosis were selected. Diagnoses of choriocarcinoma and secretory status of endometrium were reviewed. LHCGR expression of endometrium was evaluated by immunostaining. Results: Endometrial morphology was classified as secretory or nonsecretory. The 15 secretory specimens included 2 highly secretory and 13 common secretory specimens. The 31 nonsecretory patterns included 1 hyperplasia without atypia, 7 disordered proliferations, 13 typical proliferations, and 10 resting endometria. Among these, 11 specimens with overall nonsecretory patterns showed focally weak secretory changes surrounding the choriocarcinoma lesion. Secretory patterns were observed in classic choriocarcinomas (8/17) and monomorphic choriocarcinomas (7/21) but not in scanty-trophoblast choriocarcinomas (0/8). Secretory changes appeared significantly less frequently in patients who received multi-agent chemotherapy (4/25) than in those who did not (7/14) or received single-agent chemotherapy (4/7) (P = 0.030). The differences in age, months since the last pregnancy, pregnancy type, recurrence, specimen type, gross diameter, human chorionic gonadotropin (hCG) levels, and expression of hCG receptors were not statistically significant. Conclusions: The endometrial morphologies in choriocarcinoma were diverse, including various proliferative and secretory changes, but rarely hypersecretory changes, compared to the prevailing hypersecretory endometrium in hydatidiform moles. The variety in endometrial morphology was the consequence of ovarian hormonal disturbances of the hypothalamic-pituitary-gonadal axis by hCG from choriocarcinoma. Therefore, the endometrium may serve as a clue for histopathological diagnosis of choriocarcinoma. Our study presents the largest cohort reported to date to describe the diverse spectrum of endometrial changes in choriocarcinoma patients.

Abstract
PURPOSE/OBJECTIVE(S) The optimal combination of cytotoxic drugs along with radiotherapy (RT) is unknown. We undertook multidrug screening process to identify the most efficacious cytotoxic drugs, and appraise the efficacy of various drug combinations. MATERIALS/METHODS We reviewed 3105 patients who received 40 chemotherapy regimens with different combinations of nine drug classes and/or RT. Least absolute shrinkage and selection operator (LASSO) and multivariable Cox regression analyses were used to screen efficacious single drugs and identify optimal combinations for overall survival (OS). Inverse probability of treatment weighting (IPTW) and multivariable analyses were used to compare survival between treatment regimens. RESULTS Screening and validation revealed RT, asparaginase (ASP), and gemcitabine (GEM) to be the most efficacious single modality/drugs. RT remained an important component of first-line treatment, whereas ASP was a fundamental drug of non-anthracycline (ANT)-based regimens. Addition of RT to non-ANT-based or ASP/GEM-based regimens, or addition of an ASP-drug into ANT-based or GEM/PLA-based regimens, improved 5-year OS significantly. Use of ASP/GEM-based regimens led to significantly higher 5-year OS (79.9%) compared with ASP/ANT-based (69.2%, P = 0.001), ASP/MTX-based (63.5%, P = 0.011), or ASP/NOS-based (63.2%, P<0.001) regimens. The survival benefit of ASP/GEM-based regimens over other ASP-based regimens was substantial across risk-stratified and advanced-stage subgroups. The survival benefits of a combination of RT, ASP, and GEM were consistent after adjustment for confounding factors by IPTW. CONCLUSION These results suggest that combining ASP/GEM with RT for ENKTCL is an efficacious and feasible therapeutic option, and provides a rationale and strategy for developing combination therapies.

Abstract
BACKGROUND Haematopoietic stem cell transplantation (HSCT), a standard treatment for paediatric haematological diseases, is highly associated with bloodstream infection (BSI), which may increase mortality. AIM To explore the risk factors for BSI in paediatric HSCT recipients. METHODS Three English databases and four Chinese databases were searched from inception to March 17th, 2022. Eligible studies included randomized controlled trials, cohort studies, and case-control studies that enrolled HSCT recipients aged ≤18 years and reported BSI risk factors. Two reviewers independently screened studies, extracted data, and assessed the risk of bias. Using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE), certainty of body of evidence was assessed. FINDINGS Fourteen studies involving 4602 persons were included. The incidences of BSI and associated mortality in paediatric HSCT recipients were approximately 10-50% and 5-15%, respectively. Meta-analysis of all studies revealed that previous BSI before HSCT (relative effect (RE): 2.28; 95% confidence interval (CI) 1.19-4.34, moderate certainty) and receiving an umbilical cord blood transplant (RE: 1.55; 95% CI: 1.22-1.97, moderate certainty) were probably associated with an increased risk of BSI. Meta-analysis of studies with low risk of bias reassured that previous BSI before HSCT probably increased the risk of BSI (RE: 2.28; 95% CI: 1.19-4.34, moderate certainty), and revealed that steroid use (RE: 2.72; 95% CI: 1.31-5.64, moderate certainty) was likely a risk factor whereas autologous HSCT was probably a protective factor of BSI (RE: 0.65; 95% CI: 0.45-0.94, moderate certainty). CONCLUSION These findings could inform the management of paediatric HSCT recipients, helping identify who may benefit from prophylactic antibiotics.

Abstract
BACKGROUND Bacterial infections are common during induction therapy in children and adolescents with acute leukaemia and may cause infection-related mortality. AIM To determine the efficacy and safety of prophylactic antibiotics in paediatric patients with acute leukaemia receiving induction chemotherapy. METHODS From three English databases and four Chinese databases, we searched for randomized controlled trials (RCTs) and cohort studies that compared prophylactic antibiotics to placebo, no prophylaxis, or that compared one antibiotic versus another in paediatric patients with acute leukaemia undergoing induction chemotherapy. Two reviewers independently screened the studies, extracted data, and assessed the risk of bias using Cochrane Risk of Bias 2 tool and Newcastle-Ottawa Scale, and the certainty of evidence using Grading of Recommendations Assessment, Development, and Evaluation (GRADE). FINDINGS Two RCTs and ten cohort studies were finally included. For children with acute lymphoblastic leukaemia, antibiotic prophylaxis, including levofloxacin, sulfamethoxazole-trimethoprim, or other antibiotics, probably reduced bacteraemia (risk ratio (RR): 0.44; 95% confidence interval (CI): 0.33-0.60; moderate certainty) without significantly increasing Clostridioides difficile infection (CDI) or invasive fungal infection. Levofloxacin reduced the CDI rate (RR: 0.08; 95% CI: 0.01-0.62; high certainty). Ciprofloxacin prophylaxis probably reduced infection-related mortality (RR: 0.12; 95% CI: 0.01-0.97; moderate certainty). In children with acute myeloid leukaemia, ciprofloxacin plus vancomycin may reduce febrile neutropenia (RR: 0.79; 95% CI: 0.66-0.94; low certainty). Individual studies indicated that prophylaxis increased antibiotic exposure but reduced non-preventive antibiotic exposure. CONCLUSION In children with acute leukaemia undergoing induction therapy, antibiotic prophylaxis may improve the bacterial infection and mortality.

Abstract
Drawing on social cognitive career theory (SCCT) and trait activation theory, this study investigated how and when career exploration affects career outcomes in early adulthood with an integrated conceptual framework. Data came from a two-wave survey of young Chinese adults ( N = 239). This study examined a serial mediation model in which career exploration related to career satisfaction and person-job fit via career success criteria clarity (CSCC) and career decision making self-efficacy (CDSE) sequentially. Results showed, as expected, that more career exploration was related to higher career satisfaction and better person-job fit via higher career success criteria clarity and CDSE. In addition, results indicated that the indirect effect of career exploration on career outcomes becomes stronger when family socioeconomic status is lower. The current research provided insights into the underlying mechanisms between career exploration and career outcomes and the findings offered practical implications for both career educators and consultants.

Abstract
Drug potency assessment plays a crucial role in cancer chemotherapy. The selection of appropriate chemotherapy drugs can reduce the impact on the patient's physical condition and achieve a better therapeutic effect. Various methods have been used to achieve in vitro drug susceptibility assays, but there are few studies on calculating morphology and texture parameters quantitatively based on phase imaging for drug potency assessment. In this study, digital holography microscopy was used to get phase imaging of ovarian cancer cells after adding three different drugs, namely, Cisplatin, Adriamycin, and 5-fluorouracil. Based on the reconstructed phase imaging, four parameters of ovarian cancer cells changed with time, such as the average height, projected area, cluster shade, and entropy, were calculated. And the half-inhibitory concentration of cells under the effect of different drugs was calculated according to these four parameters. The half-inhibitory concentration, which can directly reflect the drug potency, is associated with the morphological and texture features extracted from phase images by numerical fitting. So, a new method for calculating the half-inhibitory concentration was proposed. The result shows that the morphological and texture feature parameters can be used to evaluate the sensitivity of ovarian cancer cells to different drugs by fitting the half-inhibitory concentration numerically. And the result provides a new idea for drug potency assessment methods before chemotherapy for ovarian cancer.

Abstract
AIM To evaluate the role of dual-energy computed tomography perfusion (DECTP) imaging in differentiating invasive thymomas (ITs), thymic cancers (TCs), and lymphomas in adults. MATERIALS AND METHODS Ninety-five patients with solid masses in the prevascular mediastinum who underwent DECTP examinations were enrolled in this study. The perfusion parameters (blood flow, BF; blood volume, BV; mean transit time, MTT; permeability surface, PS) and spectral parameters (water concentration, WC; iodine concentration, IC; normalised iodine concentration, NIC; the slope of spectral radiodensity [Hounsfield units] curve, λHU) of the lesions were analysed. RESULTS There were no differences in the MTT or WC values among ITs, TCs, and lymphomas (all p>0.05). The IC, NIC, and λHU values in the optimal arterial and venous phases and PS values of TCs were higher than those of ITs and lymphomas (all p<0.05), and there were no differences between ITs and lymphomas (all p>0.05). The BF and BV values of lymphomas were lower than those of ITs and TCs (all p<0.05), and there were no differences between ITs and TCs (all p>0.05). The cut-off values for BF and BV used to differentiate lymphomas from ITs and TCs were 42.83 ml/min/100 g and 4.66 ml/100 g, respectively (area under the receiver operating characteristic curve: 0.847 and 0.839; sensitivity, 80.6% and 82.1%; specificity, 75% and 71.4%; accuracy, 78.9% and 81.1%). CONCLUSIONS The perfusion and spectral parameters of DECTP imaging help to identify ITs, TCs, and lymphomas, and BF and BV values help to differentiate lymphomas from ITs and TCs.

Abstract
About 75% of epithelial ovarian cancer (EOC) patients suffer from relapsing and develop drug resistance after primary chemotherapy. The commonly used clinical examinations and biological tumor tissue models for chemotherapeutic sensitivity are time-consuming and expensive. Research studies showed that the cell morphology-based method is promising to be a new route for chemotherapeutic sensitivity evaluation. Here, we offer how the drug resistance of EOC cells can be assessed through a label-free and high-throughput microfluidic flow cytometer equipped with a digital holographic microscope reinforced by machine learning. It is the first time that such type of assessment is performed to the best of our knowledge. Several morphologic and texture features at a single-cell level have been extracted from the quantitative phase images. In addition, we compared four common machine learning algorithms, including naive Bayes, decision tree, K-nearest neighbors, support vector machine (SVM), and fully connected network. The result shows that the SVM classifier achieves the optimal performance with an accuracy of 92.2% and an area under the curve of 0.96. This study demonstrates that the proposed method achieves high-accuracy, high-throughput, and label-free assessment of the drug resistance of EOC cells. Furthermore, it reflects strong potentialities to develop data-driven individualized chemotherapy treatments in the future.

Abstract
OBJECTIVES This study aimed to detect the expression of progranulin (PGRN) and elucidate associations with clinical features in dermatomyositis (DM) patients with anti-melanoma differentiation-associated gene 5 (anti-MDA5) antibody. METHODS We enrolled 40 DM patients with anti-MDA5 antibody, 20 patients with antisynthetase syndrome (ASS; disease control), and 20 healthy individuals (healthy control, HC). The clinical features of patients with anti-MDA5 antibody and anti-histidyl-tRNA antibody were collected. The level of PGRN in the serum was tested by ELISA. RESULTS The PGRN levels in DM patients with anti-MDA5 antibody (166.74 ± 97.95 ng/ml) were significantly higher than those in patients with ASS (82.66 ± 40.50 ng/ml; p < 0.001) and in HC (42.34 ± 18.69 ng/ml; p < 0.001). Patients with rapid progressive interstitial lung disease (RP-ILD) in DM with anti-MDA5 antibody (213.57 ± 114.05 ng/ml) had higher levels of PGRN than those without RP-ILD (135.51 ± 72.41 ng/ml; p = 0.012). ROC analysis showed an AUC value at 0.715 (95% CI, 0.541-0.888) for diagnosis of RP-ILD in DM patients with anti-MDA5 antibody. The expression of PGRN was positively correlated with the levels of ALT, AST, CK, LDH and ferritin (all p < 0.05). CONCLUSIONS Our results indicated PGRN had great potential as a valuable serum marker of RP-ILD in DM with anti-MDA5 antibody. Key Points The level of PGRN was elevated in DM patients with anti-MDA5 antibody, especially for those with RP-ILD.

Abstract
OBJECTIVE To explore the expression characteristics of ELK3 and its role in the occurrence, progression and prognosis of gastric cancer. METHODS We analyzed the expression characteristics of ELK3 in gastric cancer based on E-MTAB-6693 dataset and explored the prognostic value of ELK3 using Kaplan-Meier survival analysis and univariate and multivariate Cox regression analysis. Chip-Atlas, ChipBase, Genes Transcription Regulation Database, and hTFtarget were used for predicting the target genes of ELK3 and constructing the transcription regulation network. Functional enrichment analysis of the target genes was performed using R software. The proportions of infiltrating immune cells in gastric cancer were analyzed using Cibersort tool, and the Pearson coefficients between ELK3 and these cells were calculated. The expression profile of ELK3 was verified based on Gene Expression Profiling Interactive Analysis and Human Protein Atlas databases. We also collected 5 pairs of gastric cancer and adjacent tissue samples and detected the expression of ELK3 at both the mRNA and protein levels using RT-PCR and Western blotting. RESULTS In public datasets and clinical samples, ELK3 was highly expressed in gastric cancer (P < 0.05), and its expression increased with the progression of M stage, AJCC stage, and perineural invasion (P < 0.05). ELK3 expression was correlated with N stage, AJCC stage, Lauren classification, differentiation, pathological classification, and microsatellite status of gastric cancer (P < 0.05). A high expression of ELK3 was associated with significantly reduced overall survival and disease-free survival of the patients, and served as an independent prognostic factor of gastric cancer (P < 0.05). Comprehensive analysis identified 176 potential target genes of ELK3, and enrichment analysis showed that ELK3 may regulate Rap1, AMPK, chemokines, VEGF, TNF, and tumor PD-L1/PD-1 signaling (PP < 0.05). The expression of ELK3 was negatively correlated with regulatory T cells, follicular helper T cells, and CD8+T cells in gastric cancer (P < 0.05). CONCLUSION ELK3 acts as an oncogene in gastric cancer, and its high expression may promote the occurrence, progression and immune escape of gastric cancer.

Abstract
Objectives: Despite recent advances in the treatment of rheumatoid arthritis (RA), few population-based studies have assessed the mortality rates and the underlying causes of death (UCDs) among patients with RA and RA-associated interstitial lung disease (RA-ILD). This study evaluated the trends in mortality rates, demographic characteristics, and UCDs among patients with RA-ILD.Method: Using data from death certificates (1999-2018) from the US Centers for Disease Control and Prevention Multiple Cause of Death files, we explored the trends in mortality rates and UCD for patients with RA and RA-ILD. Moreover, we examined the crude and age-standardized mortality rates (ASMRs) for such patients.Results: Among patients with RA or RA-ILD, ASMR variation decreased over 20 years. The ASMR ratio of RA-ILD to RA decreased by 5.84%. The ASMR for RA and RA-ILD stratified by gender or age group also decreased. The change in the ASMR ratio of RA-ILD to RA trended downwards in women and upwards in men. Arthropathies and ILD were the most frequent UCDs for RA-ILD, while arthropathies and ischaemic heart disease were the most frequent UCDs for RA.Conclusions: Although RA and RA-ILD presented a downward trend in mortality, RA combined with ILD may reduce life expectancy. Specifically, the mortality rate for patients with RA-ILD remained relatively stable during the study period when ILD was the UCD, suggesting the need for active prevention, early diagnosis, and effective management of RA-ILD.

Abstract
We present sensing time-lapse morphogenesis of living bone cells under micro-fluidic shear stress (FSS) by digital holographic (DH) microscopy. To remove the effect of aberrations on quantitative measurements, we propose a numerical and automatic method to compensate for aberrations based on a convolutional neural network (CNN). For the first time, the aberration compensation issue is considered as a regression task where optimal coefficients for constructing the phase aberration map act as responses corresponding to the input aberrated phase image. We adopted tens of thousands of living cells' phase images reconstructed from digital holograms for training the CNN. The experiments demonstrate that, based on the trained network, phase aberrations can be totally removed in real-time without any hypothesis of object and aberration phase, knowledge of the setup's physical parameters, and the operation of selecting background regions; hence, the morphogenesis of the bone cells under FSS is accurately detected and quantitatively analyzed. The results show that the proposed method could provide a highly efficient and versatile way to investigate the effects of micro-FSS on living biological cells in microfluidic lab-on-chip platforms thanks to the combination of phase-contrast label-free microcopy with artificial intelligence.

Abstract
OBJECTIVE To investigate the effect of long non-coding ribonucleic acid (lncRNA) AK023948 (AK0) on rats with postmenopausal osteoporosis via the phosphoinositide 3-kinase/protein kinase B (PI3K/AKT) signaling pathway. MATERIALS AND METHODS Firstly, postmenopausal osteoporosis rat models were established to obtain osteoblasts. The phosphorylation level of AKT was analyzed by controlling the expression of AK0 gene in osteoblasts. Finally, XTT was used to analyze the proliferation of osteoblasts and the messenger ribonucleic acid (mRNA) expression level of caspase in AK0 gene knockout (KO) rat model. RESULTS In the bone tissue of postmenopausal osteoporosis rats, the levels of phospho-PI3K (p-PI3K), p-Akt, and p-phosphoinositide-dependent kinase-1(PDK1) were significantly decreased (p<0.05). In rat model osteoblasts, the overexpression of AK0 gene upregulated the phosphorylation level of AKT, while the interference with small interfering RNA (siRNA) in AK0 gene decreased that of AKT. Knocking out AK0 gene led to the down-regulation of phosphorylation level of AKT in cells. Moreover, if the AK0 gene was re-expressed in the KO rat model cells, the phosphorylation level of AKT was restored to a certain extent, but still lower than that after the overexpression of AK0 gene. Although the proliferation rate of osteoblasts in estrogen deficiency-related osteoporosis rats was low, the growth rate of osteoblasts with AK0 KO was remarkably lower than that in blank control group (p<0.05). It was also found that there was a certain correlation between AK0 gene and osteoblast apoptosis. CONCLUSIONS LncRNA AK0 can regulate the phosphorylation level of AKT in osteoblasts of rats with estrogen deficiency-related osteoporosis through the PI3K/AKT signaling pathway, thus regulating the proliferation of osteoblasts. It is speculated that lncRNA AK0 may be an important factor in regulating the PI3K/AKT signaling pathway.

Abstract
OBJECTIVE The aim of this study was to explore the role of micro ribonucleic acid (miR)-133 in the apoptosis of human placental trophoblasts through the Ras homolog gene family (Rho)/Rho-associated coiled-coil forming protein kinase (ROCK) signaling pathway. PATIENTS AND METHODS The plasma samples were collected from 30 patients with pre-eclampsia (PE) undergoing treatment and 30 healthy subjects (control group) who received physical examination in our hospital. The Reverse Transcription-Polymerase Chain Reaction (RT-PCR) was utilized to measure the expression of miR-133 in PE patients and healthy people. Meanwhile, blood pressure, urine protein content, liver function, and kidney function were detected in patients of both groups as well. Subsequently, the placental trophoblasts were extracted and transfected with inhibitors and miRNA mimics to suppress and overexpress miR-133, respectively. The transfection efficiency was determined by RT-PCR. The levels of interleukin-6 (IL-6), IL-1, and tumor necrosis factor-alpha (TNF-α) were measured in both groups. The terminal deoxynucleotidyl transferase-mediated deoxyuridine triphosphate-biotin nick end labeling (TUNEL) assay was performed to determine the apoptosis of trophoblasts. Next, the RT-PCR and Western blotting were carried out to detect the expressions of the Rho/ROCK pathway. Furthermore, the influence of miR-133 on the apoptosis of trophoblasts in human placenta tissues through Rho/ROCK was comprehensively observed. RESULTS In vivo experiments demonstrated that the urinary protein content, miR-133 level, systolic blood pressure, diastolic blood pressure, and liver function and renal function indexes were significantly elevated in pre-eclampsia (PE) patients in comparison with normal subjects (p<0.05). After transfection of mimics and inhibitors, the expression of miR-133 was remarkably up- and down-regulated, respectively. The content of the inflammatory factors in miR-133 mimics group was overtly higher than the other two groups. The TUNEL staining results showed that the number of apoptotic cells significantly increased and decreased in the miR-133 mimics group and miR-133 inhibitors group, respectively. Subsequent experiments indicated that the expressions of apoptosis gene Caspase3, pathway gene, and protein ROCKI were notably up-regulated in miR-133 mimics group. However, they were evidently down-regulated in miR-133 inhibitors group than in the control group. In addition, a consistent trend was observed in the protein expression level. CONCLUSIONS MiR-133 participates in the development and progression of PE through the Rho/ROCK signaling pathway, which may affect the apoptosis of trophoblasts in the placenta tissues.

Abstract
Objective: The incidence of breast cancer in Chinese women continues to rise. The large breast cancer cohort studies in China are relatively scarce. There are many bottlenecks in the construction of large clinical cohort for breast cancer diagnosis, treatment, and prognoses, such as inconsistent standards, high rates of lost follow-up, repeated construction, and inability to share. To better solving the difficulties and problems faced by large-scale clinical cohort research in China, this project will cooperate with several tertiary A hospitals to establish a breast cancer cohort in Chinese women. It also provides a data platform and technical support for breast cancer multi-center clinical cohort research. Methods: Based on the evidence-based medicine and expert opinion and consensus, we established a breast cancer cohort standardized indicator set-recording baseline information, diagnosis and treatment-related information of the enrolled patients, and collecting biological specimens. According to the technical specification of long-term follow-up for the endpoint, data management, and data security and in the large population-based cohort study, a standardized follow-up system for the diagnosis, treatment, and prognosis of breast cancer prospective cohorts is formed. Results: Based on standardized data sets and the computer discipline's advantage from the University of Science and Technology Beijing, we integrate the new information technology methods, including dynamic information collection terminals and social networks. Thus, the quality of control programs on compliance and intelligence data was improved, and a Chinese women breast cancer cohort database was developed. By February 2020, 12 147 patients were included in the clinical cohort database. Biological specimens'resources in cohort construction were collected and cooperated with Shandong University to research the multi-center quality control system and shared evaluation system of biobanks. Building an open and shared biobank network and forming a full chain of breast cancer research platform. Conclusion: With the implementation of the "13(th) Five-Year Plan" precision medicine research, this study provides a research foundation for precision diagnosis and treatment of breast cancer and provides data support for the country to formulate relevant medical policies.

Abstract
OBJECTIVE To elucidate the expression pattern and biological function of circular RNA ZNF609 (circ-ZNF609) in gastric cancer (GC). PATIENTS AND METHODS Circ-ZNF609 expression in GC tissues and adjacent normal tissues (ANT) was determined by quantitative Real Time-Polymerase Chain Reaction (qRT-PCR). The regulatory effect of circ-ZNF609 on growth and metastasis of GC cells was evaluated through the Cell Counting Kit-8 (CCK-8), colony formation and transwell invasion assay, respectively. GC cell apoptosis influenced by circ-ZNF609 was examined by flow cytometry. The binding between circ-ZNF609 and miRNA-145-5p was verified by the Dual-Luciferase reporter gene assay. Finally, a series of rescue experiments were conducted to explore the mechanism of the circ-ZNF609/miRNA-145-5p axis in regulating GC progression. RESULTS QRT-PCR data revealed a higher level of circ-ZNF609 in GC tissues relative to ANT. Identically, circ-ZNF609 was highly expressed in GC cell lines relative to controls. The knockdown of circ-ZNF609 in BGC823 and MGC803 cells suppressed proliferative and invasive abilities. MiRNA-145-5p was predicted to be the target gene of circ-ZNF609 by bioinformatics, and further verified by the Dual-Luciferase reporter gene assay. Rescue experiments showed that miRNA-145-5p knockdown partially reversed the regulatory effect of circ-ZNF609 on growth and metastasis of GC cells. CONCLUSIONS Circ-ZNF609 promotes proliferative and invasive abilities of gastric cancer cells by inhibiting miRNA-145-5p expression as a ceRNA, thus accelerating gastric cancer progression.

Abstract
Drawing on the goal-setting theory and social cognitive career theory (SCCT), this study empirically proposes an operational definition of career success criteria clarity (CSCC) and further explores its impact on career satisfaction, person–job fit, and subjective well-being through the mediating role of career decision-making self-efficacy (CDSE). A pilot study of 231 samples showed that the CSCC scale had good reliability and validity. To further test the effects of CSCC on crucial employment outcomes, as well as the mediating role of CDSE, 240 employees were included in an additional survey. Structural equation modeling path analysis supported all the expected hypotheses. Results indicated that: (1) CSCC was positively correlated to career satisfaction; (2) CSCC was positively correlated to person–job fit; (3) CSCC was positively correlated to subjective well-being; (4) CSCC was positively correlated to CDSE; (5) CDSE fully mediated the relationship between CSCC and career satisfaction; (6) CDSE fully mediated the relationship between CSCC and person–job fit; and (7) CDSE partly mediated the relationship between CSCC and subjective well-being. The results contributed to social cognitive career theory model and provided suggestions for both the career educators and consultants.

Abstract
Recent evidences have consistently reported lower glutamate (Glu) levels in various brain regions, including the medial prefrontal cortex (mPFC), in chronic schizophrenia but findings in the early (EP) or in the prodromal phase of the disorder are equivocal. Although regular cannabis use has been associated with an increased risk of subsequent psychosis and with a perturbed Glu signalling, to date, the critical question of whether or not Glu abnormalities exist in EP and are related to cannabis use remains unanswered. Magnetic resonance spectroscopy was used to measure [GlumPFC] of 35 EP subjects (18 of whom were regular cannabis users) and 33 healthy controls (HC). For correlative analysis, neuropsychological performances were scored by a comprehensive cognitive battery. [GlumPFC] was lower in EP users comparing to both HC and EP non-users (P = 0.001 and P = 0.01, respectively), while no differences were observed between HC and EP non-users. In EP users Glu declined with age (r = −0.46; P = 0.04) but this relationship was not observed in non-users. Among neuropsychological profiles, working memory was the only domain that differentiates patients depending on their cannabis use, with users having poorer performances. In summary, our research revealed that cannabis use in EP is associated with Glu decreased levels, which are normally not seen in the early phase of the disorder. This finding is in line with previous 1H-MRS studies in cannabis users without a psychotic disorder and sheds light for the role of cannabis use in the progression of the disease.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
Staphylococcus aureus and Pseudomonas aeruginosa are largely the cause of morbidity and mortality in both hospital and community settings. These pathogens remain the important cause of pulmonary infections in patients with cystic fibrosis with a worldwide prevalence. Although, antibiotics are efficient measures of treating bacterial lung infections, the occurrence of antibiotic resistant bacteria has been encouraging the researchers to explore novel therapeutic approaches. It has been discovered that certain lactic acid bacteria possess protective effects against bacterial and viral respiratory infections. The aim of present study was to investigate the capability of orally administered L. acidophilus to ameliorate S. aureus and P. aeruginosa pulmonary infections. Animals were exposed to aerosol of pathogenic suspension. After 24 hours of infection, L. acidophilus treatment was administered orally for 7 consecutive days. Evaluation of tissue bacteriology, histopathology and serum cytokinomics were performed. In parallel, human alveolar A549 cells were utilized to determine possible role of probiotic on pulmonary infections. Oral administration of L. acidophilus significantly (P<0.05) alleviate lung bacterial load and severity of infection as depicted by our histopathological studies. Results obtained from cytokinomics revealed that pro-inflammatory cytokines induced due to lung infection were suppressed in oral probiotic treatment groups. In addition, treatment with L. acidophilus induced murine lung anti inflammatory, IL-10 cytokine level. Current work suggests that orally administered L. acidophilus in mice is able to attenuate S. aureus and P. aeruginosa induced lung cytotoxicity by modulation of host immune response.

Abstract
BACKGROUND Cerebral ischemia reperfusion (CIR) injury is the main pathological mechanism of ischemia stroke, and oxidative stress (OS) plays a vital role during the process of CIR. Recent studies have found that OS can activate MAPK pathway, which mainly functions as a mediator of cellular stresses. It revealed that H2S may exhibit multiple biological functions as a neuroprotector through protecting against OS-induced neuronal injury. But how H2S can attenuate ischemia/reoxygenation injury through MAPK signaling is not clear. The protective mechanism of exogenous hydrogen sulfide (H2S) on oxygen glucose deprivation/reoxygenation (OGD/R) at physiological doses in SH-SY5Y cells were investigated in this study. METHODS DCFH- DA probe is used to measure intracellular ROS, Real-time PCR and Western blot are used to detect the levels of p38 MAPK, ERK3 and Nrf2. CCK-8 is used to detect cell viability. RESULTS Comparing with the normal control group, the expressions of ERK3, p38MAPK and Nrf2 mRNA in other three groups were downregulated at the beginning of 24h. After 24h, the expressions of ERK3, p38MAPK and Nrf2 were upregulated significantly compared with the normal control group. When the cells were pretreated with 200μM NaHS at the beginning of 24h, the expressions of ERK3, p38MAPK and Nrf2 were decreased much more significantly than OGD/R and NaHS groups. CONCLUSION The present study demonstrated that exogenous H2S exerts a protective effect against OGD/R-induced injury by enhancing the activation of the ERK3, p38MAPK and Nrf2 mRNA.

Abstract
There are many drugs that affect postoperative cognitive function in patients under general anesthesia. Pentanethaquine hydrochloride (PHC), as a new type of anti-cholinergic drug, has been widely used. In clinical practice, many patients, especially elderly patients, have suffered from obvious postoperative cognitive dysfunction, but the incidence of pulmonary infection, reduced probably due to the decease of secretion production. Therefore, the effect of PHC on postoperative cognitive functions and inflammatory factors in elderly lung cancer patients under general anesthesia were mainly discussed to determine the clinical advantages and disadvantages. Ninety elderly patients undergoing thoracoscopic surgery for lung cancer under general anesthesia were selected and divided into PHC group (group A, n = 30), atropine group (group B, n = 30) and normal saline control group (group C, n = 30). The incidence of postoperative blurred vision was higher in group A compared to group B and C (both p < 0.05). The incidence of other adverse reactions was higher in group A compared to group C (all p < 0.05), but there was no difference between group A and group B (all p > 0.05). There was no significant difference in preoperative and day 1 post-surgery mini-mental state examination (MMSE) scores among the three groups (both p > 0.05), but the day 1 post-surgery MMSE scores of three groups were lower (all p < 0.05). PHC increased the incidence of postoperative cognitive impairment and postoperative delirium in elderly lung cancer patients undergoing thoracoscopic surgery under general anesthesia, but reduced the incidence of postoperative pulmonary complications possibly by reducing the expression of pro-inflammatory cytokines.

Abstract
Objective: To analyze docetaxel (T) and carboplatin (C) combined with trastuzumab (H) -TCH regimen as neoadjuvant systemic therapy in early breast cancer patients with human epidermal growth factor receptor 2 (HER-2) positive. Methods: From January 2008 to December 2014, the data of patients diagnosed as early breast cancer in Breast Disease Center of Peking University First Hospital were retrospective reviewed. The data of patients with HER-2 positive conducted TCH neoadjuvant therapy and surgery, and with the complete clinicopathological information were analyzed. Results: A total of 77 cases were enrolled in this study. We defined G2+ G3+ G4+ G5 as responsive group according to Miller-Payne grading system, the responsive rate was 84.4% (65/77). The rate of complete pathological remission (pCR) was 39.0% (30/77). The 5-year disease free survival (DFS) was 87.3%, and 5-year overall survival (OS) was 93.6%. There was a significant difference between DFS and OS in the responsive group and non-responsive group (DFS: χ2=6.762, P=0.009; OS: χ2=5.062, P=0.024). Conclusion: TCH is an effective neoadjuvant therapy for patients with HER-2 positive breast cancer, and the toxic and side effects were under control.

Abstract
Objective: To evaluate the predictive value of MRI features and pathological parameters on local recurrence, metastasis and progression free survival (PFS) for locally advanced rectal cancer after neoadjuvant chemoradiotherapy and subsequent total mesorectal excision surgery. Methods: A retrospective analysis of 95 patients with locally advanced rectal adenocarcinoma who underwent total mesorectal excision after neoadjuvant chemoradiotherapy was performed. Univariate and multivariate analyses were performed to evaluate the predictive value of MRI features before chemoradiation and postoperative pathological parameters on progression free survival. Results: Among the 95 cases, 5 cases occured local recurrence, 21 cases developed, 3 cases including both locally recurrence and distant metastasis, 19 died and 47 had no recurrence or metastasis at the last of follow-up. Univariant analysis showed that MRI signs before chemoradiation, namely, mr circumferential resection margin, mr levator ani muscle invasion, mr lymphatic vessel invasion, mr tumor deposition and postoperative pathological parameters, yp circumferential resection margin, yp lymphatic vessel invasion were related to PFS (P<0.05). Multivariate analysis of Cox proportional hazard model showed that mr lymphatic vessel invasion and mr tumor deposition were independent factors for PFS (OR=2.774 and 3.029, P<0.05). Conclusions: Lymphatic vessel invasion and tumor deposition on MRI are independent prognostic factors for progression free survival of locally advanced rectal cancer after neoadjuvant chemoradiotherapy and TME surgery. To some extent, MRI signs can assess local recurrence and distant metastasis in locally advanced rectal cancer patients after neoadjuvant chemoradiotherapy and mesorectal excision.

Abstract
Objective: To explore the utility of circulating tumor DNA detection in early breast cancer by using next-generation sequencing. Methods: This exploratory study of circulating tumor DNA detection is for early invasive breast cancer patients treated in Breast Disease Center, Peking University First Hospital from December 2015 to July 2016. Plasma samples were collected and were used to isolate plasma cell-free DNA.Exons or hotspots of 247 cancer related genes were sequenced by next-generation sequencing. Mutations and their correlation with clinic-pathological factors were analyzed. The correlation between mutations and clinic-pathological factors was evaluated by χ(2) test or Fisher's exact test. Results: Seventy-five patients were enrolled in this study. All patients were female and aged from 31 to 88 years with median age of 58 years. All patients' clinic-pathological records were complete. Sixty-four mutations in 18 genes (ALK, BCR, ERBB2, ROS1, PDGFRA, EGFR, FGFR2, CYP1B1, CALR, CASP7, BRAF, FGFR1, FGFR3, MET, NRAS, PTEN, KIT, SOD2) were detected in 47 (62.7%) among all 75 patients.Exons were captured in 10 genes, and mutations in 2 of 3 genes analyzed were clustered. Gene mutations were not correlated with menopausal status, histological type, primary tumor (T), regional lymph nodes (N), TNM stage, histological grade, estrogen receptor status, progesterone receptor status, human epidermal growth factor receptor 2 status, Ki-67 and molecular subtype (all P>0.05). Conclusion: Circulating tumor DNA sequencing by next-generation sequencing was useful for detecting breast cancer-related mutations.
