  • Screening of immune related gene and survival prediction of lung adenocarcinoma patients based on LightGBM model

    Lung cancer is one of the malignant tumors with the greatest threat to human health, and studies have shown that some genes play an important regulatory role in the occurrence and development of lung cancer. In this paper, a LightGBM ensemble learning method is proposed to construct a prognostic model based on immune relate gene (IRG) profile data and clinical data to predict the prognostic survival rate of lung adenocarcinoma patients. First, this method used the Limma package for differential gene expression, used CoxPH regression analysis to screen the IRG to prognosis, and then used XGBoost algorithm to score the importance of the IRG features. Finally, the LASSO regression analysis was used to select IRG that could be used to construct a prognostic model, and a total of 17 IRG features were obtained that could be used to construct model. LightGBM was trained according to the IRG screened. The K-means algorithm was used to divide the patients into three groups, and the area under curve (AUC) of receiver operating characteristic (ROC) of the model output showed that the accuracy of the model in predicting the survival rates of the three groups of patients was 96%, 98% and 96%, respectively. The experimental results show that the model proposed in this paper can divide patients with lung adenocarcinoma into three groups [5-year survival rate higher than 65% (group 1), lower than 65% but higher than 30% (group 2) and lower than 30% (group 3)] and can accurately predict the 5-year survival rate of lung adenocarcinoma patients.

  • Effects of Smoking on Vibration Response Imaging

    Objective To explore the characteristics of vibration response imaging ( VRI) among heavy smokers whose pulmonary function is normal. Methods 67 heavy smokers with normal pulmonary function, 60 healthy non-smokers, and 60 patients with COPD were recruited. History taking, physical examination, lung function test, chest X-ray, and VRI examination were performed. The difference of VRI dynamic imaging between the three groups was analyzed. Results VRI vibration energy curve which appeared low, flat, sunken-in, and single peak accounted for 43.3% , 16.4% , 16.4% , and 14.9% respectively in the heavy smokers, accounted for 6.7% , 3.3% ,0% , and 0% respectively in the healthy nonsmokers, accounted for 60% , 33.3% , 18.3% , and 16.7% respectively in the COPD patients. The results between the heavy smokers and the healthy non-smokers were significantly different. Compared with the heavy smokers, the COPD patients exhibited more low and flat in expiration period. The energy peak value ratio of inspiration and expiration phase in the heavy smokers, the healthy non-smokers, and the COPD patients were 0.56,0.74, and 0.54 respectively. There was no significant difference between the heavy smokers and the COPD patients in peak value ratio of inspiration and expiration phase. Conclusion The vibration energy curve of the VRI in heavy smokers with normal pulmonary function is significantly different fromhealthy nonsmokers, but there is no significant difference between heavy smokers and COPD patients.

  • Bronchiolitis obliterans associated with lymphoma and paraneoplastic pemphigus: one case report and literature review

    Objective To explore the clinical characteristics, diagnose and treatment of bronchiolitis obliterans (BO) associated with lymphoma and paraneoplastic pemphigus (PNP). Methods One patient with BO associated with lymphoma and paraneoplastic pemphigus was presented and literatures which searched through Wanfang Med online and PubMed on this subject were reviewed. Results A 44-year-old woman was admitted to this hospital because of oral ulcer for two years, and persistent dyspnea for fourteen months. She had been diagnosed with PNP one year earlier. Pulmonary function displayed severe obstructive ventilator dysfunction, negative response to the bronchodilator. Chest CT showed bronchiolectasis. The ratio of neutrophils increased in bronchoalveolar lavage fluid. The pathology of ultrasound-guided neck and inguinal lymph node biopsy showed non-Hodgkin’s lymphoma. Based on the clinical presentation, the image and pathology of this patient, the diagnosis of having PNP with BO secondary to the lymphoma was made. After 10 cycles of CHOP chemotherapy, lymphoma and PNP went into remission, but the patient died from respiratory failure. The literatures were reviewed and 15 patients were found, out of them 60% (9/15) were female, 47% (7/15) follicular lymphoma and 47% (7/15) diagnosis of clinical BO which did not be supported by pathology. Lymphoma-PNP-BO was a clinical syndrome and 67% of the initial presentations were PNP. Patients died within 7 to 60 months. Conclusions BO associated with lymphoma and PNP is rare and the most common initial presentation is PNP. BO is the major cause of death. Treatments included chemotherapy, corticosteroid and immunosuppressor, lymphoma and PNP can be alleviated, but BO is aggravating.

  • Study on the correlation between PIK3CA/TP53 gene mutations and molecular typing andhistological grading of breast cancer

    ObjectiveTo provide reference for further treatment by analyzing the relationship between mutant genes of breast cancer and histological classification and molecular typing of breast cancer.MethodsRetrospectively collectted the pathological specimens of 46 breast cancer patients who treated by the Dongguan Maternal and Child Health Hospital and the Dongguan Houjie Hospital between February 2016 and August 2017 without chemotherapy. Among the selected 46 breast cancer patients, we detected tumor tissue estrogen receptor (ER)/ pregnancy hormone receptor (PR)/human epidermal growth factor receptor-2 (HER-2) status by immunohistochemistry and classified the pathological tissue section. By using multiple PCR techniques, we detected 207 hot mutation regions of the 50 extended tumor-related genes on the semiconductor sequencing platform.ResultsThere were 8 cases of grade Ⅰ, 18 cases of grade Ⅱ, 20 cases of grade Ⅲ in 46 breast cancer patients according to histological grade. Of the 46 cases, there were 23 cases of Luminal B, 9 cases of Luminal A, 9 cases of HER-2 (+), 5 cases of type besal-like according to ER/PR/HER-2 expression status. Moreover, we found that there were 33 gene locus mutations of 8 genes, including AKT1, APC, BRAF, CDKN2A, KRAS, PTEN, PIK3CA, and TP53. Among of them, the mutation of PIK3CA gene took the most of 24 cases, followed by TP53 (18 cases), 2 cases of CDKN2A gene mutation, and 1 case in the remaining four types of genes respectively. we found that the gene mutations of breast cancer were not related to the histological classification and molecular type (P>0.05), the PIK3CA gene mutation was related to the histological classification of breast cancer, the lower the histological classification level, the higher PIK3CA gene mutation rate (P<0.05). TP53 gene mutation was not related to histological grading and molecular type (P>0.05).Conclusions The PIK3CA gene mutation rate in patients with histological grading Ⅰ level increased significantly. The combination of PIK3CA gene mutation and histological grading of breast cancer may become a molecular biological indicator to judge the degree of malignancy and prognosis of breast cancer.

  • Artificial intelligence based Chinese clinical trials eligibility criteria classification

    Subject recruitment is a key component that affects the progress and results of clinical trials, and generally conducted with eligibility criteria (includes inclusion criteria and exclusion criteria). The semantic category analysis of eligibility criteria can help optimizing clinical trials design and building automated patient recruitment system. This study explored the automatic semantic categories classification of Chinese eligibility criteria based on artificial intelligence by academic shared task. We totally collected 38 341 annotated eligibility criteria sentences and predefined 44 semantic categories. A total of 75 teams participated in competition, with 27 teams having submitted system outputs. Based on the results, we found out that most teams adopted mixed models. The mainstream resolution was applying pre-trained language models capable of providing rich semantic representation, which were combined with neural network models and used to fine-tune the models with reference to classifier tasks, and finally improved classification performance could be obtained by ensemble modeling. The best-performing system achieved a macro F1 score of 0.81 by using a pre-trained language model, i.e. bidirectional encoder representations from transformers (BERT) and ensemble modeling. With the error analysis we found out that from the point of data processing steps the data pre-processing and post-processing were very important for classification, while from the point of data volume these categories with less data volume showed lower classification performance. Finally, we hope that this study could provide a valuable dataset and state-of-the-art result for the research of Chinese medical short text classification.
