PET-CT radiomics by integrating primary tumor and peritumoral areas predicts E-cadherin expression and correlates with pelvic lymph node metastasis in early-stage cervical cancer.

Objectives: To explore the role of radiomics in integrating primary tumor and peritumoral areas based on PET-CT scans for predicting E-cadherin (E-cad) expression in early-stage cervical cancer (ESCC) and its correlation with pelvic lymph node metastasis (PLNM).

Methods: Ninety-seven ESCC patients who had undergone PET-CT scans were retrospectively analyzed. The ROI of primary tumors, peritumoral areas, and plus tumors were semi-automatically segmented on PET-CT images.

[Problems and solutions in modern research of traditional Chinese herbal pieces processing technology].

Chinese medicine processing is the main feature that distinguishes traditional Chinese medicine from natural medicine and plant medicine, and is the main feature in clinical medication of traditional Chinese medicine. The research of Chinese medicine processing technology is an important link to realize standardization and standardization of Chinese herbal pieces, with urgent need to attract high attention. At present, there are still many problems in the research of processing technology of Chinese herbal pieces, mainly including inconsistent processing technology, large differences in process technology parameters, and unstable production technology of Chinese herbal pieces, resulting in uncontrollable quality of Chinese herbal pieces and affecting the clinical efficacy of Chinese medicine.

Does dexmedetomidine as a neuraxial adjuvant facilitate better anesthesia and analgesia? A systematic review and meta-analysis.

Background: Neuraxial application of dexmedetomidine (DEX) as adjuvant analgesic has been invetigated in some randomized controlled trials (RCTs) but not been approved because of the inconsistency of efficacy and safety in these RCTs. We performed this meta-analysis to access the efficacy and safety of neuraxial DEX as local anaesthetic (LA) adjuvant.

Methods: We searched PubMed, PsycINFO, Scopus, EMBASE, and CENTRAL databases from inception to June 2013 for RCTs that investigated the analgesia efficacy and safety for neuraxial application DEX as LA adjuvant.
