Randomized Controlled Trial
Effect of ultrasound-guided nerve blocks on anesthesia and pulmonary function in patients undergoing distal radius fracture surgery.
This study aimed to assess the impact of ultrasound (US)-guided nerve blocks (NBs) on anesthesia and their protective effect on pulmonary function (PF) in patients undergoing distal radius fracture (DRF) surgery. A total of 122 patients undergoing DRF surgery between April 2020 and June 2023 were included. According to the type of peripheral NB technique, these patients were randomized into a control group (CG; n = 60) receiving brachial plexus block (BPB) using blinded techniques, and an observation group (OG; n = 62) receiving US-guided supraclavicular BPB. ⋯ Despite reductions in PF parameters and IL-10 levels after intervention, the OG maintained higher values than the CG. IL-6 levels increased significantly in the OG but remained lower than in the CG. In conclusion, US-guided NBs demonstrated significant anesthetic efficacy and apparently reduced anesthesia adverse events while also exerting a protective effect on PF in DRF surgery patients.

Multicenter Study Observational Study
Are the tumor microenvironment characteristics of pretreatment biopsy specimens of colorectal cancer really effectively predict the efficacy of neoadjuvant therapy: A retrospective multicenter study.
More and more studies had pointed out that the tumor microenvironment characteristics based on colorectal cancer (CRC) pretreatment biopsy specimens could effectively predict the efficacy of neoadjuvant therapy, but under hematoxylin and eosin (HE) staining, whether the tumor microenvironment characteristics observed by pathologists could predict the efficacy of neoadjuvant therapy remains to be discussed. We collected 106 CRC patients who received neoadjuvant treatment and surgical resection from 3 hospitals. The number of mitosis, inflammation degree, desmoplastic reaction (DR), necrosis, tumor-stroma ratio (TSR) and tumor budding (TB) of CRC pretreatment biopsy specimens were observed under HE staining, and the degree of tumor pathological remission of CRC surgical specimens after neoadjuvant treatment was evaluated. ⋯ However, we found that for colon cancer, rectal cancer was more likely to benefit from neoadjuvant therapy (P = .024). In addition, we further analyzed the impact of mitosis, inflammation degree, DR, necrosis, TSR and TB on neoadjuvant therapy in rectal cancer, and found that there was no predictive effect. By analyzing the characteristics of tumor microenvironment of CRC pretreatment biopsy specimens under HE staining, such as mitosis, inflammation degree, DR, necrosis, TSR and TB, it was impossible to effectively predict the efficacy of neoadjuvant therapy for CRC.

Case Reports
Clinical features and genetic analysis of 5 cases of infantile-type glycogen storage disease type II: Case reports.
Clinical and genetic mutation analysis was performed on 5 infantile glycogen storage disease type II children in Chinese mainland. ⋯ Peripheral blood GAA gene testing and alpha-glucosidase enzyme activity testing is an effective method for diagnosing this disease.

This study aims to assess the associations among students' perceptions of climate change, university social responsibility (USR), and environmental sustainability practices at a medical university. It also aims to identify the factors associated with these elements. A cross-sectional self-report study was conducted with a total sample of 416 undergraduate students from a medical university in Taiwan during October 2019. ⋯ In addition, school year (non-freshmen vs freshmen, -1.64 [0.65]) and environmental sustainability practices (per 1-point increase, 0.23 [0.06]) were associated with the total score of students' perception of USR (R-square = 6.57%). Promoting environmental sustainability among university students can be achieved by implementing USR-oriented courses or activities. Our research is pioneering in investigating and discussing the perceived USR and environmental sustainability practices among university students in Taiwan.

The use of 3 biomarkers - cystatin-C (Cys-C), retinol-binding protein (RBP), and ischemia-modified albumin (IMA) - for the clinical classification and outcome of coronary heart disease (CHD) has not been adequately evaluated. We explored the serum levels of these 3 markers and evaluated their diagnostic and prognostic values in patients with CHD. This retrospective case-control study, conducted between June 2017 and June 2018, included 201 patients with CHD hospitalized at the Henan Provincial People's Hospital and 127 healthy individuals from Henan Provincial People's Hospital as controls. ⋯ Each indicator has clinical significance in the diagnosis and prognosis of CHD, with RBP being the most significant. The AUC value for CHD detection using a combination of the 3 indicators was 0.783, and the sensitivity and specificity values were 78% and 74.6%, respectively. Simultaneous detection of Cys-C, RBP, and IMA could be an optimal method for early diagnosis and prognosis of CHD.
