Abstract
OBJECTIVE Acute respiratory infections are a major global public health concern. However, there are few epidemiological studies investigating pathogens associated with respiratory tract infections in Guizhou Province, China. METHODS We collected 17,850 blood samples from Guizhou Provincial People's Hospital between November 2018 and May 2023 to investigate the epidemiological characteristics of respiratory pathogens and their spread during the SARS-CoV-2 epidemic in Guizhou Province. RESULTS We identified influenza virus and Mycoplasma pneumoniae as the predominant pathogens involved in acute respiratory infections in the study area. Immunoglobulin M positivity for respiratory syncytial virus, influenza virus, and M. pneumoniae showed a strong correlation with the clinical diagnosis of pneumonia. Seasonal epidemic patterns were observed for influenza A and B viruses. Following the SARS-CoV-2 outbreak, there was a significant decrease in the positive rates for most respiratory pathogens, particularly influenza A and B, Legionella pneumophila, and respiratory syncytial virus. CONCLUSION This retrospective study contributes to the epidemiological evidence regarding respiratory pathogens in Guizhou Province, thereby enhancing the surveillance network for respiratory pathogens in China and providing valuable guidance for local hospitals.

Abstract
Background: High technical complexity limits the wide use of transradial approach (TRA) chemoembolization in the management of liver cancer. We sought to construct a thoracoabdominal aorta CTA-based nomogram model to identify ideal candidates for TRA chemoembolization in patients with liver cancer. Methods: Patients who had received thoracoabdominal aorta CTA before TRA chemoembolization from 2018 to 2020 were retrospectively enrolled and randomly divided into a training set and a validation set. The clinical characteristics and CTA features were collected to build a clinical model. Univariate and multivariate analyses were used to identify significant clinical-radiological variables. A CTA-based nomogram model was constructed by using multivariate logistic regression analysis. The predictive performance, as well as discrimination efficacy of the model, was evaluated by ROC analysis and calibration plot. Results: Vascular variation (P=0.028), Myla classification (P=0.030), length from left subclavian artery to the left subclavian artery (P=0.017), and angle between common hepatic artery and abdominal aorta (P=0.017) were identified as important factors associated with the technical complexity of TRA chemoembolization, indicated by fluoroscopy time of the total procedure. The CTA-based nomogram model was established by these abovementioned variables, which demonstrated good predictive ability in both the training cohort (AUC=0.929) and validation cohort (AUC= 0.769), with a high C-index of 0.928 and 0.827 respectively. Moreover, satisfactory calibrations were confirmed by the Hosmer-Lemeshow test with P values of 0.618 and 0.299 in the training cohort and validation cohort. Conclusion: Our study constructs a novel CTA-based nomogram, which can serve as a useful tool to identify ideal candidates for TRA chemoembolization in patients with liver cancer.

Abstract
Objective: To analyze the early outcome of one-stage hybrid technique in the treatment of Stanford type-A aortic dissection involving the arch and compare its therapeutic efficacy with the classical frozen elephant trunk technique (FET). Methods: A total of 106 patients with Stanford type-A aortic dissection involving the arch in Department of Cardiac and Vascular Surgery, 1st Affiliated Hospital of Soochow University from October 2015 to October 2019 was collected. All patients in this group were treated with one-stage hybrid technique (modified arch debranching technique) without deep hypothermia circulation. Meanwhile, 30 patients with Stanford type A dissection involving the arch who underwent FET from January 2014 to September 2015 were collected. The therapeutic effects of the two surgical methods were analyzed and compared. Results: The age [M (Q1, Q3)] of 106 patients in hybrid group was 49.0 (40.0, 55.0) years, including 89 males and 17 females. The age [M(Q1, Q3)] of 30 patients in FET group was 49.5 (41.5, 65.3) years, including 24 males and 6 females. The time [M(Q1, Q3)] of using ventilator in hybrid group was 56.0 (38.0, 72.0) h, which was shorter than 127.0 (92.0, 145.0) h in FET group (P<0.001). The incidence of cerebral infarction in hybrid group was 2.8% (3 cases), which was lower than 13.3% (4 cases) in FET group (P=0.042); the incidence of postoperative renal insufficiency in hybrid group was 7.5% (8 cases), which was lower than 23.3% (7 cases) in FET group (P=0.023); the ICU time [M (Q1, Q3)] in hybrid group was 8.0 (6.0, 10.0) d, which was shorter than 14.0 (8.3, 24.0) d in FET group (P<0.001). Conclusion: Compared with FET, one-stage hybrid technology is safer and more effective in the treatment of Stanford type A aortic dissection involving the arch. Its short-term therapeutic efficacy appears good.

Abstract
OBJECTIVE Albumin-to-alkaline phosphatase ratio (AAPR), a newly developed blood biomarker, has been reported to have prognostic value in several types of cancer. This study aimed to investigate the predictive value of AAPR in patients with early-stage hepatocellular carcinoma (HCC) undergoing radiofrequency ablation (RFA) as initial therapy. METHODS This retrospective study analyzed 445 patients with newly diagnosed HCC undergoing RFA as initial therapy. A series of survival analyses were performed to evaluate the prognostic value of AAPR. Univariate and multivariate analyses were performed to identify independent prognostic factors. An AAPR-based nomogram was constructed, and its predictive performance was validated. RESULTS Patients with a low AAPR had a significantly reduced recurrence-free survival (RFS) and overall survival (OS) compared with those with a high AAPR. AAPR was found to be an independent prognostic indicator and showed superior discrimination efficacy than other liver function indices. The AAPR-based nomogram had a concordance index value of 0.72 (95% confidence interval [CI]: 0.65-0.79) in the training cohort and 0.72 (95% CI: 0.63-0.81) in the validation cohort, which significantly outperformed other existing staging systems. CONCLUSIONS AAPR serves as a promising indicator of prognosis in patients with early-stage HCC undergoing RFA. The AAPR-based nomogram might contribute to individualized prognosis prediction and clinical decision making.

Abstract
Cannabinoid receptor has been shown to be overexpressed in various types of cancers, especially non-small cell lung cancer. As a result, it could be used as novel target for anticancer treatments. Because receptor-dependent 4D-QSAR generates conformational ensemble profiles of compounds by molecular dynamics simulations at the binding site of the enzyme, this work describes the synthesis, biological activity evaluation and 4D-QSAR studies of 4,5-dihydro-1,3,4-oxadiazole derivatives targeting cannabinoid receptor. Compared with WIN55,212-2, compound 5 f showed the best antiproliferative activity. The receptor-dependent 4D-QSAR model was generated by multiple linear regression method using QSARINS. Leave-n-out cross-validation and chemical applicability domain were performed to analyse the independent test set and to verify the robustness of the model. The best 4D-QSAR model showed the following statistics: r2 = 0.8487, Q2LOO = 0.7667, Q2LNO = 0.7524, and r2Pred = 0.8358.

Abstract
Identifying novel prognostic biomarkers for hepatocellular carcinoma (HCC) and then, develop an effective individualized treatment strategy remain extremely warranted. The prognostic role of sulfiredoxin-1(SRXN1), an antioxidant enzyme, remains unknown in HCC. This study aimed to explore the prognostic implications of SRXN1 in HCC patients after partial hepatectomy. The expression of SRXN1 in HCC and normal tissue were analyzed using the patients from the public databases and Zhongshan Hospital. The Cox regression, Kaplan-Meier survival analysis, and time-dependent receiver operating characteristic curves were performed to identify the predictive role of SRXN1 expression on HCC patients. A prognostic nomogram based on SRXN1 expression was constructed and validated to further confirm the predictive power of SRXN1 as a prognostic biomarker. Finally, functional enrichment analysis and protein-protein interaction network analysis of SRXN1 and its associated genes were conducted. The results showed that SRXN1 was upregulated in HCC samples compared with the normal liver tissues. Patients with SRXN1 upregulation had shorter survival time. SRXN1 overexpression was significantly correlated with advanced clinicopathological parameters. The prognostic nomogram based on SRXN1 expression was proved to be more accurate than routine staging systems for the prediction of overall survival. Protein-protein interaction network analysis demonstrated the first neighbor genes of SRXN1 mainly participated in response to oxidative stress. In brief, SRXN1 could be a prognostic biomarker for the management of HCC.

Abstract
Dysregulation of cell migration–inducing hyaluronan-binding protein (CEMIP) is
associated with the growth and metastasis of multiple malignancies. But, the
underlying mechanism by which CEMIP contributes to colorectal cancer (CRC)
remains undocumented. The association of CEMIP or miR-140-3p expression with
clinicopathological characteristics and prognosis in CRC patients was analyzed
by the tissue microarray and TCGA dataset. MiR-140-3p-specific binding with
CEMIP was confirmed by luciferase report assay. In vitro experiments were
conducted to assess the effects of CEMIP on the growth and invasion of CRC
cells. Consequently, we found that CEMIP expression was dramatically elevated in
CRC tissues and associated with a poor prognosis in CRC patients. The
upregulation of CEMIP was attributable to the dysregulation of miR-140-3p rather
than its genetic and epigenetic alterations. Ectopic expression of CEMIP
facilitated the cell viability, colony formation, and invasive potential, but
silencing of CEMIP reversed these effects. Furthermore, CEMIP was identified as
a direct target of miR-140-3p and attenuated miR-140-3p-induced
anti-proliferation effects by regulating c-Myc, E-cadherin, and Twist-1
expression. MiR-140-3p indicated a negative correlation with CEMIP expression
and was an independent prognostic factor of tumor recurrence in CRC patients.
Taken together, CEMIP is regulated by miR-140-3p and promotes the growth and
invasion of CRC cells. MiR-140-3p/CEMIP axis may represent the potential markers
for CRC patients.

Abstract
Objectives LncRNA nuclear‐enriched abundant transcript 1 (NEAT1) participates in the development and progression of multiple malignancies. However, the molecular mechanism by which NEAT1 contributes to colorectal cancer (CRC) remains unclear. Methods The association between lncRNA NEAT1 expression and clinicopathological characteristics and prognosis in patients with CRC was analysed by TCGA RNA‐sequencing data. MTT, colony formation, flow cytometry, transwell assays and a xenograft tumour model were used to assess the functions of NEAT1. Bioinformatics and spearman correlation analysis were used to identify the NEAT1‐specific binding with miRNAs, and luciferase gene report and RIP assays were performed to confirm the interaction between miR‐193a‐3p (miR‐193a) and NEAT1 in CRC cells. Results Upregulation of NEAT1 expression was significantly correlated with TNM stage, poor survival and tumour recurrence in patients with CRC, and acted as an independent prognostic factor for tumour recurrence. Knockdown of NEAT1 suppressed cell proliferation, colony formation abilities and invasive potential and induced cell apoptosis, but overexpression of NEAT1 reversed these effects. Furthermore, NEAT1 was confirmed to act as a sponge of miR‐193a, and knockdown of NEAT1 attenuated miR‐193a inhibitor‐induced tumour promoting effects and L17RD expression in CRC cells. miR‐193a harboured negative correlation with NEAT1 and IL17RD expression in CRC specimens. In vivo experiment further validated the inhibitory effects of NEAT1 knockdown on xenograft tumour growth. Conclusion Our findings demonstrate that lncRNA NEAT1 acts as an oncogenic role in CRC cells by sponging miR‐193a and may represent a potential marker for CRC patients.

Abstract
bHLH/PAS proteins play important roles in tumor progression. Lost or reduced expression of single-minded homolog 2 (SIM) as well as aryl hydrocarbon receptor repressor (AHRR) has been observed in cancerous human tissues. Here, we investigated the role of aryl hydrocarbon receptor nuclear translocator (ARNT), another bHLH/PAS protein, in hepatocellular carcinoma (HCC). Using tissue microarray and immunohistochemistry, we found that intratumoral ARNT was inversely correlated with time to recurrence and overall survival of HCC patients after resection. Knockdown of ARNT in HepG2, HCCLM3 and HCCLM6 cells significantly shortened cell doubling time, increased S-phase cell populations and accelerated in vivo HCCLM6 growth and metastasis. After ARNT expression was rescued, prolonged cell doubling time and decreased S-phase cell populations were observed in HepG2, HCCLM3 and HCCLM6 cells. And, HCCLM6 growth and metastasis in vivo were remarkably inhibited. Screening by quantitative reverse-transcription PCR and PCR arrays revealed that cyclin E1, CDK2, Fos and Jun were negatively regulated by ARNT, whereas CDKN1C, CNKN2A, CDKN2B, MAPK11 and MAPK14 were positively regulated in HCC. According to the results of immunoprecipitation assay, both ARNT/ARNT and ARNT/AHRR complexes were clearly formed in HCCLM6 xenograft with increased ARNT expression. In summary, ARNT is an important regulator of HCC growth and metastasis and could be a promising prognostic candidate in HCC patients.

Abstract
OBJECTIVES To study biological characteristics of stable red fluorescent protein (RFP)-expressing or green fluorescent protein (GFP)-expressing HCCLM3 cell lines and those of their relevant xenograft models in nude mice. METHODS HCCLM3, a human hepatocellular carcinoma cell line with high metastatic potential was infected with RFP or GFP full-length cDNA via lentivirus. Stable RFP-expressing or GFP-expressing HCCLM3 cells, namely HCCLM3-R and HCCLM3-G, were subcutaneously injected and two patient-like metastatic models of HCCLM3-R and HCCLM3-G in nude mice were established using surgical orthotopic implantation from subcutaneous tumor tissues. Cell proliferation, karyotype, biomarker expression, tumor growth, and metastasis of HCCLM3-R and HCCLM3-G were analyzed in vitro and in vivo. RESULTS RFP and GFP genes were integrated in genomic DNA of HCCLM3. HCCLM3-R and HCCLM3-G expressed red and green fluorescence, stable and intense, 300 days after 60 consecutive passages, and also positively expressed CK8+, P16+, AFP+ and negatively expressed HBsAg-. Their biomarker expression and karyotype were found to be similar to those of the parental HCCLM3, and their tumorigenesis occurred in 10 nude mice without exception after a subcutaneous injection and did the same in 20 nude mice after an orthotopic implantation. The results showed that the rate of spontaneous metastasis to the liver and lung and peritoneal seeding was 100, 100, and 90%, respectively. CONCLUSION Stable fluorescent protein-expressing HCCLM3-R and HCCLM3-G xenografts in nude mice could be of two useful models for studying mechanisms of hepatocellular carcinoma growth and metastasis in real time.

Abstract
OBJECTIVE To study the clinical safety and effect on local recurrence in unresectable small hepatocellular carcinoma treated by radiofrequency ablation (RFA) with and without chemotherapy through a prospective randomized trial. METHODS Thirty-eight unresectable small hepatocellular carcinoma patients with diameter </= 3 cm were selected, of which 27 patients have been followed up for 1 year. Through a prospective randomized trial, 12 patients were in the RFA group and 15 patients in the RFA combined with systemic chemotherapy group. RFA was given image-guided. The regimen of systemic chemotherapy: EADM 50 mg on day 1, 3; CDDP 40 mg on day 1, 3 and FUDR 500 mg on day 1, 2, 3. After RFA treatment, liver function, WBC count and complications were observed on day 1, 4, 7; CT scan was performed in 1, 6, 12 months. The safety and local recurrence were analyzed. RESULTS There was no local recurrence of the tumor in the two groups 1 month after RFA treatment. The 6- and 12-month local recurrence rates were significantly lower in the combined group than that in RFA group alone (P < 0.01). There were no severe complications in the two groups, and nor was there any significant difference in liver function and WBC count. CONCLUSION RFA combined with systemic chemotherapy is safe, and it can reduce the local recurrence of unresectable small hepatocellular carcinoma </= 3 cm in diameter.

Abstract
Volumetric optical disks comprising multiple data layers have been proposed to multiply recording density. Owing to the presence of out-of-focus data layers, interlayer cross talk is induced in readout. An optical model was developed to study the readout process and the effect of interlayer cross talk on the readout of dual-layer read-only optical disks. Schemes to improve the readout characteristics by suppression of the interlayer cross talk were proposed. Experiments that agreed well with the simulation resulted.
