Device-assisted intravesical chemotherapy versus bacillus Calmette-Guerin for intermediate or high-risk non-muscle invasive bladder cancer: a systematic reviewer and meta-analysis.

PURPOSE: To investigate the effectiveness and safety of device-assisted intravesical chemotherapy compared to Bacillus Calmette-Guerin (BCG) in the treatment of patients with intermediate- and high-risk non-muscle-invasive bladder cancer (NMIBC). METHODS: In February 2023, a systematic search was conducted on the PubMed, Cochrane, and Embase databases. Following the PRISMA guidelines, a systematic review and meta-analysis of the primary outcomes of interest were performed. The review was prospectively registered on PROSPERO under the registration number CRD42023398559. RESULTS: A total of 10 studies involving 1160 patients were included. The results of the meta-analysis showed that compared to BCG, device-assisted chemotherapy had a lower recurrence rate (OR: 0.63, 95% CI: 0.48-0.84, p = 0.001), longer recurrence-free survival (OR: 0.64, 95% CI: 0.47-0.88, p = 0.006), and lower incidence of fever (OR: 0.18, 95% CI: 0.08-0.44, p = 0.0002). However, no significant differences were observed between the two groups in terms of progression, overall survival, progression-free survival, disease-free survival, overall adverse events, serious adverse events, hematuria, allergy, and general discomfort. Subgroup analysis revealed that neither chemohyperthermia (CHT) nor electromotive drug administration (EMDA) showed statistically significant differences in oncological outcomes compared to BCG. Regarding adverse events, both CHT and EMDA groups showed lower rates of fever compared to the BCG group (OR: 0.26, 95% CI: 0.10-0.67, p = 0.005, and OR: 0.14, 95% CI: 0.05-0.37, p < 0.0001, respectively). No significant differences were observed in the remaining adverse events between either the CHT or EMDA group and the BCG group. CONCLUSION: Device-assisted intravesical chemotherapy appears to be a safe and viable alternative to BCG for patients with intermediate and high-risk NMIBC, showing comparable oncological outcomes and adverse events.

Demethylzeylasteral attenuates hepatic stellate cell activation and liver fibrosis by inhibiting AGAP2 mediated signaling.

BACKGROUND: Liver fibrosis is a common cause of chronic liver disease. If left untreated, it can ultimately develop into liver cirrhosis or hepatocellular carcinoma. However, a direct antifibrotic therapy is currently unavailable. A re-examination of existing chemicals might be a potential strategy for finding more lead compounds against liver fibrosis. Demethylzeylasteral (T-96), a naturally occurring bioactive compound found in Tripterygium wilfordii Hook. f. (TwHf) possesses multiple pharmacological properties. However, its antifibrotic potential has not yet been fully evaluated. PURPOSE: This study aimed to investigate the antifibrotic properties of T-96 and its underlying molecular mechanisms. METHODS: The antifibrotic properties of T-96 were investigated in three types of hepatic stellate cells (HSCs) and in a CCl4-induced liver fibrosis mouse model. The effect of T-96 on the proliferation, migration, and activation of HSCs was detected using CCK-8 and scratch/wound healing assays. Hepatic inflammation and fibrosis were evaluated by H&E, Masson's trichrome stain, and Sirius Red staining. The expression of inflammatory and fibrogenic genes was detected by quantitative real-time PCR (qRT-PCR) and western blotting. RNA sequencing (RNA-seq) was performed to explore the potential molecular mechanisms mediating the antifibrotic effect of T-96, which was verified by dual-luciferase reporter assay, qRT-PCR, western blotting, immunofluorescence, and immunoprecipitation analysis. RESULTS: The T-96 treatment significantly suppressed the proliferation, migration, and activation of HSCs in vitro. The administration of T-96 attenuated hepatic injury, inflammation, and fibrosis progression in mice with CCl4-induced liver fibrosis. In addition, the RNA-seq of fibrotic liver tissues and subsequent functional verification indicated that the key mechanisms of the antifibrotic effect of T-96 were mediated by suppressing the expression of AGAP2 (Arf GAP with GTPase-like domain, ankyrin repeat and PH domain 2), inhibiting the subsequent phosphorylation of focal adhesion kinase (FAK) and protein kinase B (AKT), and finally reducing the expression of fibrosis-related genes. CONCLUSION: Our results provide the first insight that T-96 exerts potent antifibrotic effects both in vitro and in vivo by inhibiting the AGAP2 mediated FAK/AKT signaling axis, and that T-96 may serve as a potential therapeutic candidate for the treatment of liver fibrosis.

Proton pump inhibitor utilisation and potentially inappropriate prescribing analysis: insights from a single-centred retrospective study.

OBJECTIVES: This study aimed to characterise the prescribing patterns and evaluate the appropriateness of the prescribed proton pump inhibitors (PPIs) in adult patients via a review of electronic medical records in a single-centred hospital. DESIGN: All patients admitted to the outpatient department of Jinshan Hospital, Fudan University, Shanghai, between 1 January 2018 and 31 December 2018 were evaluated. Individuals aged 18 years or above and with at least one dispensing for PPIs were identified as PPI users. New PPI users were defined as a subject who did not receive any dispensing for PPIs in the year prior to the index date. Baseline characteristics of PPI users and their therapies were described by treatment indication, economic indicators and co-prescription, overall and separately. SETTING: The prescription database was retrieved from the hospital information system of Jinshan Hospital, Fudan University. RESULTS: Among 18 435 identified PPI users in 2018, 14 219 patients (aged 18 years or above) who had at least one dispensing PPIs were new users (77%), and among them, men accounted for 47%. The mean treatment duration was 23 days. Omeprazole was the most commonly prescribed drug. PPIs are inappropriately prescribed in 50% (13 589/25 850) of prescriptions. Prescription appropriateness analysis indicated that the unapproved indications for PPI new users accounted for 47%; among them, the proportion of gastritis diagnosis was 34%. The proportion of PPI new users with co-prescription of glucocorticosteroids (GCs) who have risk factors accounted for 24% and lower than other co-prescription. A majority of PPI users (73%) reported high-dose PPI prescription. The defined daily dose of oral pantoprazole was the highest, and injectable omeprazole had the highest defined daily cost. In contrast, only the drug utilisation index value of oral esomeprazole was less than 1.0. CONCLUSION: The results indicate the challenge of PPI use was accompanied by unapproved indications, frequent inappropriate co-prescription with GCs and excessive dosages. Efforts should be paid to promote rational use and ensure the choice of suitable PPI therapy in the future.

Oncolytic Adenovirus Complexes Coated with Lipids and Calcium Phosphate for Cancer Gene Therapy.

Oncolytic adenovirus (OncoAd) is a promising therapeutic agent for treating cancer. However, the therapeutic potential of OncoAd is hindered by hepatic sequestration and the host immune response in vivo. Here, we constructed a PEG/Lipids/calcium phosphate (CaP)-OncoAd (PLC-OncoAd) delivery system for ZD55-IL-24, an oncolytic adenovirus that carries the IL-24 gene. The negatively charged PLC-ZD55-IL-24 were disperse and resisted serum-induced aggregation. Compared to naked ZD55-IL-24, the systemic administration of PLC-ZD55-IL-24 in BALB/c mice resulted in reduced liver sequestration and systemic toxicity and evaded the innate immune response. In addition, masking the surface of OncoAd protected it from neutralization by pre-existing neutralizing antibody. PLC-OncoAd achieved efficient targeted delivery in Huh-7-bearing nude mice, and intravenous administration of a high dose of PLC-ZD55-IL-24 increased therapeutic efficacy without inducing toxicity. The developed PLC-OncoAd delivery system represents a promising improvement for oncolytic adenovirus-based cancer gene therapy in vivo.
