Construction and Validation of a Predictive Model for Culture Results of Mycobacterium Tuberculosis in Superficial Lymph Nodes.

Background: To establish and validate a nomogram for predicting the culture results of Mycobacterium tuberculosis in superficial lymph nodes.

Methods: The clinical data of patients with superficial lymph node tuberculosis admitted to Xi'an City Chest Hospital from November 23, 2018, to May 30, 2024, were selected and divided into a training set and a validation set according to a ratio of 7:3. Influencing factors were identified through multivariate logistic regression analyses.

Distinct roles of miR-34 family members on suppression of lung squamous cell carcinoma.

miR-34, whose mimic was used on phase I clinical trial, has been extensively reported since its dysfunction in various cancers including non-small-cell lung cancer (NSCLC). However, the roles of miR-34 family members in the progression of lung squamous carcinoma (SCC) in patients who have occupational-exposure experience are unclear yet. Here, we comprehensively investigated the expression levels of miR-34 family members in SCC patients and compared the roles of them in SCC in vitro and vivo.

[Clinical analysis of lateral cervical approach in the treatment of cervical lymphatic tuberculosis complicated with parapharyngeal space abscess].

To investigate the clinical effect of lateral cervical approach in the treatment of cervical lymphatic tuberculosis complicated with parapharyngeal space abscess. A total of 10 patients with cervical lymph node tuberculosis complicated with tuberculous abscess in parapharyngeal space were treated. Surgery was performed using a transcervical approach.
