Objective To investigate the effects of cryoanalgesia for post-thoracotomy pain on the intercostal nerves. Methods Two hundred and eight patients suffering from thoracotomy were divided into three groups, according to different analgesia received respectively. Cryoanalgesia group （n = 80）： cryoanalgesia on the intercostal nerves, intercostals nerves was freezed at -55 ℃ for 90 seconds ; patient controlled analgesia by vein （PCA group, n= 80）： patient controlled analgesia was practiced intravenously, and control group （n = 48）： Dolantin given irregularly intra-muscularly and/or tramadol orally. Severity of pain was graded by visual analogue scale. Forced expiratory volume in one second（FEV1.0） was measured and pulmonary complication after operation was compared. Results There was a statistically significant improvement in postoperative pain scores and an improvement in respiratory function tests for patients in cryoanalgesia group（X2 = 74.93,15.04,P〈0. 05）. FEV1.0 in cryoanalgesia group was significantly higher than that in control group（1. 97±0.27L vs. 1. 39±0. 14 L,P〈0. 05）. Pulmonary complication in cryoanalgesia group after operation was lower than that in control group （6. 25% vs. 31. 25%, P〈0. 05 ）, Conclusion Cryoanalgesia on post-thoracotomy pain is very effective and may improve the respiratory function after operation.
Definitive chemoradiotherapy (dCRT) is the general recommendation for the treatment of cervical esophageal cancer for organ preservation. However, the long-term survival of dCRT is not satisfactory. Surgical resection alone is not superior to dCRT in the treatment of cervical esophageal cancer. Surgical resection is often combined with laryngectomy, which will affect the quality of life. Recent evidence suggests that neoadjuvant therapy combined with surgery improves the long-term survival of cervical esophageal cancer. On the other hand, the development of technologies such as laryngeal preservation surgery and minimally invasive esophagectomy has reduced the risk of operation and improved the quality of life. This article will review the new progress in the comprehensive treatment of cervical esophageal cancer from the perspective of surgery.
Neoadjuvant therapy has become the standard treatment for locally advanced resectable esophageal cancer, significantly improving long-term survival compared to surgery alone. Neoadjuvant therapy has evolved to include various strategies, such as concurrent chemoradiotherapy, chemotherapy, immunotherapy, or targeted combination therapy. This enriches clinical treatment options and provides a more personalized and scientific treatment approach for patients. This article aims to comprehensively summarize current academic research hot topics, review the rationale and evaluation measures of neoadjuvant therapy, discuss challenges in restaging methods after neoadjuvant therapy, and identify the advantages and disadvantages of various neoadjuvant therapeutic strategies.
ObjectiveTo investigate the expressions of microRNA-155 (miR-155) in different phenotypes of activated macrophages. MethodsThe THP-1 cells underwent polarized activation into M1, M2 or tumor-associated macrophages (TAMs), and the phenotypes were confirmed by flow cytometry. The miR-155 expression was determined by qRt-PCR in M1 macrophages, M2 macrophages and TAMs. ResultsThe miR-155 expression significantly decreased in the M2 macrophages (1.83±0.337, P=0.000), TAMs (1.60±0.233, P=0.000) compared with the M1 (6.580±0.637). The phenotype of TAMs was similar to M2. There was no statistically significant difference between TAMs and M2 macrophages in the expression of miR-155 (P=0.546). ConclusionDifferent expressions of miR-155 in macrophages M1-type and M2-type may be associated with the differentiation or their cellular functions. The phenotypic characteristics TAMs may transform to macrophages to M2-type. And they may have the same functions.
