This study introduced a novel point "O" puncture approach for percutaneous kyphoplasty (PKP) in patients with L4 or L5 osteoporotic vertebral compression fracture (OVCF) and evaluated its clinical and radiographic outcomes. Between September 2019 and December 2020, we compared the clinical and radiographic outcomes in 31 cases (36 vertebrae) using the "O" entry point PKP intervention (O-PKP) and 31 cases (37 vertebrae) using transverse the process-pedicle approach PKP intervention (T-PKP). No serious postoperative complications were observed in any of the participants. Only two T-PKP patients experienced intervertebral disc space leakage. Compared with the T-PKP patients, the O-PKP patients showed shorter operative time and fluoroscopy times (P < 0.05), comparable blood loss and cement volume (P > 0.05), improved VAS and ODI scores at the final follow-up (P < 0.05), better increases in the vertebral compression ratio (P < 0.05), comparable Cobb angle (P > 0.05), comparable anteroposterior bone cement distribution, enhanced bilateral bone cement distribution (P < 0.05), and larger sagittal and transverse angles (P < 0.05). Herein, O-PKP was indicated for patients with L4 or L5 OVCF. This puncture approach showed significant advantages over T-PKP not only in terms of pain relief, surgery and fluoroscopy times but also in the puncture angle, vertebral reconstruction, and symmetrical cement distribution.

Objective: Our study aim is to explore the mechanisms of short peptide passages on intestinal dysfunction in septic mice utilizing a metabolomics approach, which provides a new scientific basis for the clinical study of sepsis.
Methods: Mices were allocated at random into four groups: control (Con), cecal ligation and puncture followed by one, three or 7 day short-peptide-based enteral nutrition group (CLP + SPEN1), (CLP + SPEN3), and (CLP + SPEN7) groups. A liquid chromatography-mass spectrometry-based metabolomics method was used to analyze changes in serum metabolites in septic mice.

The diagnosis of Lyme neuroborreliosis (LNB) requires the demonstration of intrathecal synthesis of Borrelia antibodies in a patient's cerebrospinal fluid (CSF), which involves the invasive procedure of a lumbar puncture. This study serves as a feasibility study aimed at exploring the potential of using serum samples, which are easily obtainable routine clinical samples, for LNB diagnostics via advanced metabolomics techniques. Serum samples were collected from confirmed LNB patients before and after treatment, with post-treatment samples serving as controls.

Background: Centrally inserted central catheterization (CICC) is a critical procedure in pediatric care. However, CICC in children poses greater challenges compared to adults due to anatomical and physiological differences, leading to higher complication rates. Ultrasound-guided approaches have been developed to enhance the safety and effectiveness of CICC, but the comparative efficacy of different axis approaches remains unclear.

Primary hyperparathyroidism (PHPT) is the third most common endocrine disorder, typically caused by a single parathyroid adenoma. The diagnosis of PHPT is biochemical, and the localization of abnormal parathyroid glands is usually achieved through a combination of ultrasound and technetium-99m sestamibi (99mTc-MIBI) scans. In some cases, newer imaging modalities, such as positron emission tomography-computed tomography (PET-CT) with 18F-fluorocholine or 11C-methionine, are used as second-line methods.

Background: Venipuncture and intravenous cannulation are common procedures in hospitals that often cause pain, particularly in children. Despite the availability of various local analgesia methods to alleviate needle-associated pain, the most effective approach remains unknown. The objective of this study is to compare and rank the efficacy of different local analgesia methods in reducing pain in children undergoing venipuncture and intravenous cannulation.
