Aims: A survey was conducted into the routine use of special stains on gastrointestinal (GI) biopsy specimens in histopathology departments within the National Health Service. The aim was to compare the sole use of haematoxylin and eosin (H&E) staining with the use of H&E and special stains, according to the biopsy site.
Methods And Results: One hundred and sixty-seven histopathology departments in the UK were contacted using an e-mail questionnaire. Valid return rate was 55%. Sixty-eight percent of departments employ H&E only for oesophageal biopsy specimens. Gastric specimens are stained using only H&E in 47% of departments and 53% use H&E combined with special stains. Duodenal, small and large bowel biopsy specimens are mostly stained with H&E.
Conclusions: The results show that the routine use of special stains in GI pathology in the UK is highly variable, especially for oesophageal and gastric biopsy specimens. The literature indicates that special stains in GI specimens can enhance sensitivity and specificity for the detection of pathological abnormalities, especially metaplasia and infections. The diversity of staining practice highlights the need to provide robust and evidence-based guidelines for the routine use of special stains to ensure universal best practice.

Efforts have been made to leverage technology to accurately identify tumor characteristics and predict how each cancer patient may respond to medications. This involves collecting data from various sources such as genomic data, histological information, functional drug profiling, and drug metabolism using techniques like polymerase chain reaction, sanger sequencing, next-generation sequencing, fluorescence in situ hybridization, immunohistochemistry staining, patient-derived tumor xenograft models, patient-derived organoid models, and therapeutic drug monitoring. The utilization of diverse detection technologies in clinical practice has made "individualized treatment" possible, but the desired level of accuracy has not been fully attained yet.

Background: Ischemic stroke is a prevalent and life-threatening cerebrovascular disease that is challenging to treat and associated with a poor prognosis. Astragaloside IV (AS-IV), a primary bioactive component of Astragali radix, has demonstrated neuroprotective benefits in previous studies. This study aimed to explore the mechanisms through which AS-IV may treat cerebral ischemia-reperfusion injury (CIRI).

Detection of biomarkers of breast cancer incurs additional costs and tissue burden. We propose a deep learning-based algorithm (BBMIL) to predict classical biomarkers, immunotherapy-associated gene signatures, and prognosis-associated subtypes directly from hematoxylin and eosin stained histopathology images. BBMIL showed the best performance among comparative algorithms on the prediction of classical biomarkers, immunotherapy related gene signatures, and subtypes.

Ethnopharmacological Importance: Zhili decoction (ZLD) is a traditional Chinese medicine prescription for ulcerative colitis (UC). However, the mechanism by which ZLD exerts its therapeutic effects in the context of UC remains unclear.
Aim Of Study: The aim of this study was to investigate the effects of ZLD on the gut microbiota and related fecal metabolite levels using a mouse model of UC.
