Developments and clinical experiences in collagenase chemonucleolysis for lumbar disc herniation: a narrative review.

Lumbar disc herniation (LDH) affects millions globally, with annual healthcare costs exceeding $100 billion in the United States alone, driving increasing interest in minimally invasive radiological interventions as treatment alternatives. This narrative review examines developments in collagenase chemonucleolysis for LDH, integrating a literature analysis with clinical experience. Key advancements include the transition from single-agent to combination therapies, exploration of diverse injection routes, and the progression from C-arm fluoroscopy to multi-slice CT guidance.

Synthesis of a novel starch-based emulsion gel with remarkable low-temperature stability via esterification, ozone-oxidation and ion induction.

A novel starch-based emulsion gel was designed via octenyl succinic anhydride (OSA) esterification, ozone oxidation, and ion (Ca) induction. The gel properties and low-temperature stability of emulsion gel with different oxidation time (0, 5, 10, 15, 25 min; OW-0, 5, 10, 15, 25) were systematically investigated. FTIR revealed that the oxidation of CC and -OH groups in OW-0 by ozone oxidation led to their cleavage into carbonyl groups, and than transformed to carboxyl groups.

A Sustained H/Fluorouracil-Releasing Suppository for High-efficacy and Low-Toxicity Hydrogenochemotherapy of Colon Cancer.

To attenuate the intestinal toxicity of chemotherapeutic drugs from rectal suppositories and enhance their chemotherapeutic outcome is greatly significant, but maintains a challenge. In this work, a new strategy of local synergistic hydrogenochemotherapy is proposed to attenuate side effects and enhance therapeutic efficacy based on the anti-cancer selectivity and normal cells-protecting effect of H, and construct a novel anti-cancer formulation of rectal suppository (5-FU/CSN@FAG) by fatty acid glycerides (FAG) encapsulating 5-fluorouracil (5-FU, a first-line drug for colorectal cancer treatment) and cerium silicide nanoparticles (CSN) with a sustained hydrolytic H release behavior which is synchronous with 5-FU release. The 3-week treatment with the suppository once a day can not only completely eradicate colon tumors without tumor recurrence after suppository administration withdrawal, but also efficiently protect the intestinal tract from chemotherapeutic damage.

A nomogram model based on albumin-bilirubin score for predicting 90-day prognosis in patients with acute-on-chronic liver failure.

Objective: To develop a nomogram model based on the albumin-bilirubin (ALBI) score for predicting the 90-day prognosis of patients with acute-on-chronic liver failure (ACLF) and to evaluate its predictive efficacy.

Methods: Clinical data of 290 ACLF patients at the Third People's Hospital of Nantong City, collected from December 2020 to December 2023, were analyzed. The data were divided into a training set ( = 200) and a validation set ( = 90), with August 2022 as the cut-off date.
