Pathological Diagnosis and Treatment Techniques

1. Live tissue examination: All surgical specimens, including puncture tissue specimens from various parts of the body, organ specimens, bone specimens, as well as live specimens from fiberoptic gastroscopy, bronchoscopy, and laryngoscopy, can undergo live tissue examination. The general pathology department conducts pathological examinations every day and sends pathological reports every Monday to Friday. The routine examination time is about 2 days. All pathological data is managed and printed using a computerized pathological image and text management system, with nearly half of the reports being graphic pathological reports.

2. Cytological examination: including cervical scraping, sputum smear, pleural and ascitic fluid and urine smear, various tissue puncture smear, etc. It can assist in large-scale tumor screening, such as cervical cancer vaginal smear examination.

3. Intraoperative frozen section examination: By using frozen section method, a preliminary pathological report can be issued within 30-40 minutes. Mainly used as a quick diagnostic reference during surgery, providing timely and reliable basis for clinical surgical treatment. In addition, the detection of certain antigenic substances and antibodies that need to maintain their biological activity also requires the use of frozen sections.

4. Immunohistochemical examination: There are over 50 immunohistochemical examination items, including various epithelial markers, mesenchymal markers, cell proliferative markers, oncogene proteins, etc. Used for the diagnosis and differential diagnosis of diseases, as well as to determine the prognosis and prognosis of certain malignant tumors.

5. Special staining examination: There are more than 10 types of special staining examinations, such as reticular fiber staining, Masson staining, PAS, AB, and acid fast staining, used for the diagnosis and differential diagnosis of diseases.

6. Immunofluorescence examination: used for renal biopsy and the diagnosis of certain skin diseases. This examination used frozen sections and immunofluorescence antibody staining. Through renal biopsy and immunofluorescence examination, the diagnosis of kidney disease can be clearly determined, and it is a good diagnostic method for various primary, secondary, and hereditary renal parenchymal diseases (especially diffuse renal lesions). It can provide research on various types of kidney disease and is of great significance for the treatment and prognosis of kidney disease.
