Inverted Pyramid Nanostructures Coupled with a Sandwich Immunoassay for SERS Biomarker Detection.

Cancer diagnostics often faces challenges, such as invasiveness, high costs, and limited sensitivity for early detection, emphasizing the need for improved approaches. We present a surface-enhanced Raman scattering (SERS)-based platform leveraging inverted pyramid SU-8 nanostructured substrates fabricated via nanoimprint lithography. These substrates, characterized by sharp apices and edges, are further functionalized with (3-aminopropyl)triethoxysilane (APTES), enabling the uniform self-assembly of AuNPs to create a highly favorable configuration for enhanced SERS analysis.

The impact of serum thyroid-stimulation hormone levels on the outcome of hepatitis B virus related acute-on-chronic liver failure: an observational study.

Background: Thyroid dysfunction has been reported in severe liver diseases. The aim of this study was to analyze the impact of serum thyroid-stimulation hormone (TSH) levels on the prognosis of patients with hepatitis B virus (HBV)-related acute-on-chronic liver failure (ACLF).

Methods: This retrospective cohort study included 1,862 patients with HBV-related ACLF.

Safety and efficacy of Thymosin α1 in the treatment of hepatitis B virus-related acute-on-chronic liver failure: a randomized controlled trial.

Background/purpose Of The Study: Mortality from hepatitis B virus (HBV)-related acute-on-chronic liver failure (ACLF) is high. Severe infection is the most important complication that affects the outcomes of ACLF patients. Thymosin α1 (Tα1) can improve immune imbalance and this study aimed to investigate the safety and efficacy of Tα1 treatment for HBV-related ACLF.

Derivation and Validation of a Nomogram for Predicting 90-Day Survival in Patients With HBV-Related Acute-on-Chronic Liver Failure.

Conventional prognostic models do not fully reflect the severity of hepatitis B virus (HBV)-related acute-on-chronic liver failure (ACLF). This study aimed to establish an effective and convenient nomogram for patients with HBV-related ACLF. A nomogram was developed based on a retrospective cohort of 1,353 patients treated at the Third Affiliated Hospital of Sun Yat-sen University from January 2010 to June 2016.

Effect of HELLP syndrome on acute kidney injury in pregnancy and pregnancy outcomes: a systematic review and meta-analysis.

Background: HELLP syndrome may increase adverse pregnancy outcomes, though the incidence of it is not high. At present, the impact of HELLP syndrome on P-AKI (acute kidney injury during pregnancy) and maternal and infant outcomes is controversial. Thus, we conducted a meta-analysis to find out more about the relationship between HELLP syndrome and P-AKI and pregnancy outcomes.

[To investigate the opportunity of entecavir treatment for HBeAg-negative acute-on-chronic liver].

Objective: To explore relations between the opportunities and effects of internal general treatment added Entecavir on acute-on-chronic liver failure (ACLF) of HBeAg-negative chronic hepatitis B in different score ranges of acute-on-chronic liver failure severity.

Methods: A total of 108 ACLF of HBeAg-negative chronic hepatitis B patients with different ACLF severity score were treated with internal general treatment added Entecavir. The liver failure severity scores, HBV-DNA loads during the initiation of therapy, recovery phase and in deathbed phase, courses of Entecavir administration and mortalities were studied.

Dexamethasone in outcome of patients with hepatitis B virus-related acute-on-chronic liver failure.

Background And Aim: Acute-on-chronic liver failure (ACLF) caused by hepatitis B virus (HBV) is a severe disease with high mortality. Immune injury plays an important role during the early stage of the disease. Our research aimed to investigate the safety and efficacy of dexamethasone therapy for patients with HBV-related ACLF.

[Small interfering RNA targeting to hepatitis B virus X gene and 5-aza-2'-deoxycytidineon inhibited growth of the subcutaneous implanted tumor of hepatocellular carcinoma in nude mice].

Objective: To investigate the anti-tumor effect of small interfering RNA targeting to HBV X gene (X-siRNA) and 5-aza-2'-deoxycytidine (5-aza-dC) on HBV-related hepatocellular carcinoma.

Methods: X-siRNA and control siRNA were synthesized. HepG2/GFP-HBx cells were treated with X-siRNA, and the levels of HBV X mRNA were detected by semi-quantitative reverse transcription polymerase chain reaction (RT-PCR).

Imbalance of interleukin-17-producing CD4 T cells/regulatory T cells axis occurs in remission stage of patients with hepatitis B virus-related acute-on-chronic liver failure.

Background And Aim: Although regulatory T cells (Treg) and interleukin-17-producing CD4 T cells (Th17) have been demonstrated to play opposing roles in inflammation-associated diseases, their frequency and balance in different stages of hepatitis B virus (HBV)-related acute-on-chronic liver failure (ACLF) remain unknown.

Methods: Fourteen patients with HBV-associated ACLF were studied and defined into different stages according to disease activity. Circulating Th17 cells and Treg cells were analyzed by flow cytometry, and the cytokines were quantitated by enzyme-linked immunosorbent assay.

What MELD score mandates use of entecavir for ACLF-HBV HBeAg-negative patients?

Aim: To investigate optimal timing for therapeutic efficacy of entecavir for acute-on-chronic hepatitis B liver failure (ACLF-HBV) in hepatitis B e antigen (HBeAg)-negative patients.

Methods: A total of 109 inpatients with ACLF-HBV were recruited from the Department of Infectious Diseases of the Third Affiliated Hospital, Sun Yat-sen University from October 2007 to October 2010. Entecavir 0.

[The relationship of HBeAg status with HBV DNA loads, MELD scores in patients with acute-on-chronic hepatitis B liver failure during terminal phases].

Objective: To investigate the relationship and clinical significances of HBeAg status with serum HBV DNA loads, model for end-stage liver disease (MELD) scores in patients with acute-on-chronic hepatitis B liver failure during terminal phase.

Methods: 120 fatal patients were enrolled. At three phases of 0 -14 d, 15-28 d and 29-90 d before death, they were detected serum HBeAg, HBV DNA loads order meanwhile MELD scores were calculated.

[Major constituent proteins in donkey hide and their interaction].

Objective: To analyze the constituent proteins in donkey hide, the key ingredient for Ejiao, an important traditional Chinese medicine for the blood-related conditions, in hope to eventually decipher the biochemical mechanism behind Ejiao's prominent medicinal efficacy.

Method: Two methods were employed to extract proteins in donkey skin. One used TriPure isolation reagent to extract the total proteins in donkey skin.

[Effects of glutamine granules on protein metabolism in trauma patients].

Objective: To evaluate the effect of glutamine granules on protein metabolism in severe burns and trauma patients.

Methods: 120 patients with severe burns, multiple trauma and post operation who met the requirements of the protocol joined this double-blind randomized controlled, multi-center clinical trail. Patients were randomly divided into two groups: placebo control group (P group, 60 patients) and glutamine granules treatment group (GLN group, 60 patients).
