Integrating Internet multisource big data to predict the occurrence and development of COVID-19 cryptic transmission.

With the recent prevalence of COVID-19, cryptic transmission is worthy of attention and research. Early perception of the occurrence and development risk of cryptic transmission is an important part of controlling the spread of COVID-19. Previous relevant studies have limited data sources, and no effective analysis has been carried out on the occurrence and development of cryptic transmission.

One- versus two-stage partial hepatectomy for large resectable solitary hepatocellular carcinomas determined preoperatively to have a narrow resection margin: a propensity score matching analysis.

Background: For patients with a large but resectable solitary hepatocellular carcinoma (HCC) of >5 cm in diameter, it is often difficult to achieve a sufficient resection margin. There is still no study on whether a two-stage hepatectomy to increase a narrow resection margin would be beneficial.

Methods: From August 2014 to February 2017, patients with a large but resectable solitary HCC of >5 cm and a preoperative estimated resection margin of <1.

Associating liver partition and portal vein ligation for staged hepatectomy versus sequential transarterial chemoembolization and portal vein embolization in staged hepatectomy for HBV-related hepatocellular carcinoma: a randomized comparative study.

Background: Both portal vein embolization (PVE) and associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) have merits and demerits when used in patients with unresectable liver cancers due to insufficient volumes in future liver remnant (FLR).

Methods: This study was a single-center, prospective randomized comparative study. Patients with the diagnosis of hepatitis B related hepatocellular carcinoma (HCC) were randomly assigned in a 1:1 ratio to the 2 groups.

A Study on the Correlation Between Media Usage Frequency and Audiences' Risk Perception, Emotion and Behavior.

Whether risk events can be effectively controlled and mitigated is largely influenced by people's perceptions of risk events and their behavioral cooperation. Therefore, this study used a web-based questionnaire ( = 306) to investigate the specific factors influencing people's risk perceptions and behaviors, and included a test for the difference in the effect of positive and negative emotions of the audiences. The results show that the overall model has good explanatory power ( = 61%) for the behavioral variables, and (1) how people's use of different media (especially TV and online media) significantly influenced their positive and negative emotions; (2) how people's frequency of TV use significantly influenced their risk susceptibility and how online media use significantly influenced their risk severity (with some differences in people's perceptions of efficacy between different media); (3) how people's sense of efficacy for risky events is the strongest predictor of their risk control behavior; and (4) that there are different mediating effects of different emotions and risk severity and sense of efficacy between the frequency of media use and risk control behavior.

Fabricating poly(vinyl alcohol)/gelatin composite sponges with high absorbency and water-triggered expansion for noncompressible hemorrhage and wound healing.

It is challenging for traditional hemostatic sponges to control massive and noncompressible hemorrhages in the military field and accidental trauma. In this work, a series of highly fluid-absorbent composite sponges with rapid expansion ability based on norbornene anhydride-modified poly(vinyl alcohol) and gelatin (PVA@Gel-Sps) were developed by a foaming technique, chemical and physical crosslinking reactions and lyophilization. The prepared PVA@Gel-Sp exhibited a 3500% maximum water absorption ratio with a fast water absorption speed, which was suitable for blood component concentration.

SKA3 Promotes Cell Growth in Breast Cancer by Inhibiting PLK-1 Protein Degradation.

Breast cancer (Bca) remains the most common form of malignancy affecting females in China, leading to significant reductions in the mental and physical health of those with this condition. While spindle and kinetochore associated complex subunit 3 (SKA3) is known to be linked with cervical cancer progression, whether it is similarly associated with Bca progression remains unknown. Using shRNA, we specifically knocked down the expression of SKA3 in Bca cell lines and then assessed the resultant changes in cell proliferation using CCK-8 and colony formation assays.

: To explore a method for culturing hepatocellular carcinoma and tumor-infiltrating lymphocytes (HCC-TIL) and investigate the mechanism of TIL in killing tumors. : The distribution of regulatory T cells (Treg) in HCC was detected by immunohistochemistry. Conventional TIL and oligoclonal TIL were isolated by the traditional method of enzyme digestion combined with mechanical treatment for whole HCC and micro HCC tissue block culturing method.

Overexpression of CLN3 contributes to tumour progression and predicts poor prognosis in hepatocellular carcinoma.

The aberrant expression of ceroid-lipofuscinosis 3 (CLN3) has been reported in a variety of human malignancies. However, the role of CLN3 in the progression and prognosis of hepatocellular carcinoma (HCC) remains unknown. In this study, we found that CLN3 was frequently upregulated in HCC clinical samples and HCC-derived cell lines and was significantly correlated with an APF serum level ≥20 μg/L, a tumour size ≥5 cm, multiple tumours, and the absence of encapsulation.

Exosomes derived from HBV-associated liver cancer promote chemoresistance by upregulating chaperone-mediated autophagy.

Liver cancer, which is the second leading cause of tumor-associated mortality, is of great concern worldwide due to its resistance to chemotherapeutic drugs. Transcatheter arterial chemoembolization (TACE) has previously been used as a treatment for unresectable liver tumors in China; however, the response to TACE treatment differs between patients. It has been reported that hepatitis B virus (HBV)-as sociated tumors are less sensitive to TACE treatment compared with non-HBV-associated liver cancer.

Decreased intracellular chloride promotes ADP induced platelet activation through inhibition of cAMP/PKA instead of activation of Lyn/PI3K/Akt pathway.

Decrease of chloride concentration contributes to cardiovascular diseases, however, whether decrease of chloride concentration is involved in platelet activation remains elusive. In the present study, we found that ACI patients had lower serum chloride which would be rescued after Aspirin administration. ADP induced chloride concentration reduction in platelets.

Lamp2 inhibits epithelial-mesenchymal transition by suppressing Snail expression in HCC.

Lysosomal associated membrane protein 2 (Lamp2) influences a broad range of physiological and pathological processes. However, little is known about the role of Lamp2 in hepatocellular carcinoma (HCC) metastasis. This study found that Lamp2 expression was significantly lower in HCC tissues than in adjacent nontumor tissues (ANTs), and its expression level correlated with HCC metastasis.

Aggravated intestinal apoptosis by ClC-3 deletion is lethal to mice endotoxemia.

Our previous study found that ClC-3 chloride channel functioned differently in the vascular and intestinal inflammation, the loss of ClC-3 reduced vascular inflammation but exacerbated intestinal inflammation. To furtherly clarify the role of ClC-3 chloride channels in systemic inflammation, we used LPS-induced endotoxemia model to investigate the response of wild-type and ClC-3 knockout mice to systemic inflammation. The results showed that in the LPS-induced endotoxemia model, the mortality of mice with ClC-3 deletion was significantly higher than that of wild-type mice.

Antiviral Therapy Reduces Hepatocellular Carcinoma Recurrence in Patients With Low HBV-DNA Levels: A Randomized Controlled Trial.

Background: Despite antiviral treatment has been shown to reduce hepatocellular carcinoma (HCC) recurrence after curative treatment for hepatitis B virus (HBV)-related HCC in patients with high preoperative HBV-DNA levels, it is still unclear whether antiviral therapy is useful in reducing recurrence in patients with low preoperative HBV-DNA levels.

Methods: In this randomized controlled trial, 200 patients who underwent curative resection for HCC with low baseline HBV-DNA levels were randomly assigned to receive preemptive antiviral therapy or not. The primary endpoints were recurrence-free survival.

Zinc finger protein X-linked promotes expansion of EpCAM cancer stem-like cells in hepatocellular carcinoma.

Zinc finger protein X-linked (ZFX) is frequently upregulated in multiple human malignancies and also plays a critical role in the maintenance of self-renewal in embryonic stem cells. However, the role of ZFX in liver cancer stem cells (CSCs) remains obscure. We observed that the elevated expression of both ZFX and epithelial cell adhesion molecule (EpCAM) was associated with aggressive clinicopathological features and indicated poor prognosis in patients with hepatocellular carcinoma (HCC).

Hepatitis B virus X protein promotes the stem-like properties of OV6 cancer cells in hepatocellular carcinoma.

Hepatitis B virus X protein (HBx) and cancer stem-like cells (CSCs) have both been implicated in the occurrence and development of HBV-related hepatocellular carcinoma (HCC). However, whether HBx contributes to the stem-like properties of OV6 CSCs in HCC remains elusive. In this study, we showed that the concomitant expression of HBx and OV6 was closely associated with the clinical outcomes and prognosis of patients with HBV-related HCC.

SOS response and its regulation on the fluoroquinolone resistance.

Bacteria can survive fluoroquinolone antibiotics (FQs) treatment by becoming resistant through a genetic change-mutation or gene acquisition. The SOS response is widespread among bacteria and exhibits considerable variation in its composition and regulation, which is repressed by LexA protein and derepressed by RecA protein. Here, we take a comprehensive review of the SOS gene network and its regulation on the fluoroquinolone resistance.

Cellular DDX3 regulates Japanese encephalitis virus replication by interacting with viral un-translated regions.

Japanese encephalitis virus is one of the most common causes for epidemic viral encephalitis in humans and animals. Herein we demonstrated that cellular helicase DDX3 is involved in JEV replication. DDX3 knockdown inhibits JEV replication.

Inhibitory effect of esterified lactoferin and lactoferrin against tobacco mosaic virus (TMV) in tobacco seedlings.

The inhibitory effects of esterified lactoferrin (ELF) and lactoferrin (LF) against tobacco mosaic virus (TMV) in tobacco seedlings and the underlying mechanism were investigated. ELF and LF significantly inhibited viral infection and TMV multiplication in tobacco plants. ELF showed a higher inhibition effect against TMV than LF treatment in a dose and time-dependent way.

The DEAD-box RNA helicase DDX5 acts as a positive regulator of Japanese encephalitis virus replication by binding to viral 3' UTR.

Japanese encephalitis virus (JEV), one of the causes for epidemic encephalitis, belongs to the family of Flaviviridae. In this study, we demonstrated that cellular DEAD-box RNA helicase DDX5 plays an important role in JEV replication. The knockdown of DDX5 was able to decrease JEV replication, and overexpression of DDX5 mutants lacking the helicase activity also reduced JEV replication, suggesting the helicase activity is essential for JEV replication.

Inhibitory effect of sulfated lentinan and lentinan against tobacco mosaic virus (TMV) in tobacco seedlings.

The antiviral activities of sulfated lentinan (sLNT) and lentinan (LNT) against tobacco mosaic virus (TMV) in tobacco seedlings and the underlying mechanism were investigated. Compared with LNT, sLNT showed significantly higher inhibitory effects on viral infection and TMV multiplication in a dose-dependent way, which might be due to its binding with TMV coat protein. In addition, both sLNT and LNT induced the transient production of H2O2 and expression of some defense-related genes (stilbene synthase, glucanase, acidic chitinase class IV, phenylalanine ammonia-lyase and 5-epi-aristolochene synthase) both locally and systemically.
