Objective:To investigate the anatomical variation of the T3 sympathetic ganglia and its relationship with surgical outcomes in primary palmar hyperhidrosis.Methods:A total of 86 patients with primary palmar hyperhidrosiswho underwent R4 sympathicotomy from November 2017 to September 2018 were prospectively enrolled. The anatomical variation of T3 sympathetic ganglia was observed by fluorescence thoracoscopy. The therapeutic effect and side effect were followed up after operation.The relationship between T3 anatomical variation and postoperative effect was analyzed.Results:82.6% of T3 ganglion had no anatomic variation, 17.4% of T3 ganglion shifted down to the surface of the fourth rib or intercostal space. After 1 month of follow-up, the therapeutic effect was: overly dry 2.1%, dry 39.4%, mild moist 57.0%, moist 1.4% innormalside, and 13.3%, 53.3%, 33.3%, 0 in the variation side respectively. Mann- Whitney U test showed statistically significant difference between the two groups( P=0.004). After 1 year of follow-up, the effect was 0, 36.5%, 56.9%, 6.6% in normal side, and 0, 33.3%, 63.0%, 3.7% in the variation side respectively. There was no significant difference between the two groups by Mann- Whitney U test( P=0.869). Conclusion:Fluorescence thoracoscopy showed that the variation rate of the position of T3 sympathetic ganglion was 17.4%. Postoperatively, patients with the downshift variation of T3 sympathetic ganglion have drier hands in short-term follow-up.

BACKGROUND: Lung cancer is the most common malignant tumor in clinic. The prognosis of advanced patients is poor, and the 5-year survival rate is low. Therefore, early diagnosis becomes the key to improve the prognosis of patients. In recent years, with the development of molecular biology technology, aberrant modification of some driver genes, such as methylation, has become an important method for early diagnosis of lung cancer. The purpose of the present work was to quantitatively evaluate the diagnostic value of abnormal hypermethylation in short state homeobox 2 (SHOX2) promoter region in lung cancer by evidence-based medicine. METHODS: We searched MEDLINE, EMBASE, Ovid, Web of Science and CNKI for literatures related to the relationship between SHOX2 gene promoter hypermethylation and lung cancer. The data of SHOX2 promoter hymethylation in the original study were extracted. The diagnostic sensitivity, specificity and area under receiver operating characteristic (ROC) curve of SHOX2 promoter methylation were calculated. RESULTS: Finally, 13 publications were included in this meta-analysis, and due to significant statistical heterogeneity among the studies (P<0.05) the data was pooled by random effect model. The diagnostic sensitivity and specificity of SHOX2 promoter hypermethylation in the diagnosis of lung cancer were 0.75 (95%CI: 0.74-0.77) and 0.89 (95%CI: 0.88-0.91), respectively; The positive likelihood ratio value was 6.75 (4.56-9.99), and the negative predictive value was 0.36 (0.25-0.52); The diagnostic odds ratio was 23.16 (11.34-47.31), and the area under the ROC curve was 0.9. CONCLUSIONS SHOX2 gene promoter hypermethylation is high in serum, broncholavage fluid and pleural effusion of lung cancer patients, which can be used as a biomarker for auxiliary diagnosis of lung cancer.

Lung cancer is the most common malignant tumor and the leading cause of cancer-related death worldwide. Most of the patients have distant metastasis when visiting the doctor, which seriously affects the survival time and quality of life of the patients. With the development of molecular targeted drugs, lung cancer treatment has been transformed from traditional chemotherapy to targeted therapy and precision medicine has been gradually applied in clinical practice, which can make lung cancer patients live longer and have a better quality of life. We present a case of advanced lung cancer patient who presented to Department of Thoracic Surgery of Beijing Haidian Hospital five years ago. We chose the reasonable treatment options though the genetic tests and circulating tumor DNA tests. We summarized the adverse reactions in the whole course of treatment. The comprehensive therapy we utilized, including targeted therapy, chemotherapy, antiangiogenic agents and local radiotherapy, have resulted in our patient with remaining alive. For advanced non-small cell lung cancer with epidermal growth factor receptor (EGFR) mutation positive, individualized treatment was conducted based on precise genotyping and dynamic monitoring, which can not only control the tumor, but also have mild toxic and side effects. The survival time of the patients was prolonged and the quality of life was guaranteed.
