RESUMO

Objective: To analyze the application of Chronic Obstructive Pulmonary Disease (COPD) Screening Questionnaire and pulmonary function test in dust-exposed migrant workers. Methods: In May 2019, 149 cases of dust exposed migrant workers were selected as the research subjects through the free clinic in the countryside. COPD Screening Questionnaire and lung function test were carried out to analyze the high-risk groups and the influencing factors of positive pulmonary function test results. Results: Among 149 cases of dust-exposed migrant workers, 107 (71.8%) were positive for questionnaire screening, 73 (49.0%) were positive for pulmonary function test, 75 (50.3%) were diagnosed with coal worker's pneumoconiosis, and 101 (67.8%) were diagnosed with lung function injury. The positive rate of pulmonary function of migrant workers with positive questionnaire screening results was significantly higher than that of those with negative results (P<0.05) . The results of multivariate analysis showed that compared with non-pneumoconiosis, the risk of positive pulmonary function test results was higher in dust-exposed migrant workers with stage Ⅲ pneumoconiosis (OR=16.462, 95%CI: 3.390-79.946; P<0.01) . Compared with non-smoking, the risks of positive pulmonary function test results of dust-exposed migrant workers with smoking index of 11-20 package years and >20 package years were higher (OR=19.814, 95%CI: 3.854-101.883; OR=9.733, 95%CI: 2.310-41.008; P<0.01) . Conclusion: The risk of COPD in dust-exposed migrant workers is high, so we should strengthen the early examination of the high pneumoconiosis stage and smoking population. The screening questionnaire can better screen out the high-risk groups of COPD, and it can be used as a basic screening tool.

RESUMO

Objective: To analyze the situation of hospitalized migrant workers with pneumoconiosis in Hunan Province, and to provide reference for the prevention and treatment of pneumoconiosis. Methods: In July 2019, the data of pneumoconiosis migrant workers hospitalized in Hunan Prevention and Treatment Institute for Occupational Diseases from February 2017 to February 2019 were retrospectively analyzed, and the general situation, region distribution, diagnosis and complications were analyzed. Results: From February 2017 to February 2019, a total of 6344 migrant workers with pneumoconiosis were treated, mainly distributed in Zhuzhou city (1283 cases, 20.22%) , Yiyang city (1048 cases, 16.52%) and Loudi city (783 cases, 12.34%) . Coal worker's pneumoconiosis (4242 cases, 66.87%) and silicosis (2089 cases, 32.93%) were the main types of pneumoconiosis. Among them, 1433 cases (22.59%) were in stage I, 1318 cases (20.77%) were in stage II, and 3593 cases (56.64%) were in stage III. The age of the patients was mainly between 41-60 years old (4584 cases, 72.26%) . 3869 patients (60.99%) had complications and chronic obstructive pulmonary disease (3046 cases, 48.01%) and pulmonary infection (1703 cases, 26.84%) were the most common complications. There were 1510 patients (23.80%) who had two or more complications. There were significant differences in the number of complications among patients with different diagnosis stages and age stages (χ(2)=764.43, 90.24, P<0.01) . Conclusion: Coal worker's pneumoconiosis and silicosis are the main types of pneumoconiosis among hospitalized migrant workers in Hunan Province, and most patients were in stage III. Older patients with higher pneumoconiosis stage have more complications, early diagnosis and treatment should be taken.

RESUMO

OBJECTIVE: Papillary thyroid cancer (PTC) is one type of thyroid cancer. Although it has a good prognosis, the recurrence and metastasis rates remain high. MATERIALS AND METHODS: The microarray dataset GSE66783 was downloaded from the Gene Expression Omnibus (GEO). With the R package, the differentially expressed genes (DEGs) and lncRNAs between normal adjacent tissues and cancer tissues of PTC were identified. The miRNAs that were targeted by DElncRNAs and the mRNAs that were targeted by miRNAs were discovered through miRcode and through miRTarBase, TargetScan, and miRDB, respectively. Furthermore, the ceRNA network was constructed. GO and KEGG enrichment analyses were performed on the DEGs. The PPI network of the DEGs was obtained from the STRING database, and the top 5 hub genes that had a tight correlation with the disease were obtained by using Cytoscape. Finally, the study used the Kaplan-Meier method to analyze PTC patient survival time, and the Human Protein Atlas database was used to retrieve the expression of the hub genes in normal and PTC patient tissues. RESULTS: Five hub genes showed significant differences in expression in the PPI network, and 12 lncRNA-miRNA-mRNA pathways might participate in the potential pathophysiological process of PTC. CONCLUSIONS: The study indicated that these ceRNAs might contribute to future therapies for PTC.

RESUMO

Objective: To analyze the epidemiological characteristics of pneumoconiosis in Hunan Province. Methods: In November 2018, we collected the type of work, pneumoconiosis type, pneumoconiosis stage, length of service, age of onset and complications of pneumoconiosis cases diagnosed by Hunan occupational disease prevention and control hospital from January 2017 to October 2018. A total of 3 325 cases of pneumoconiosis were collected, including 651 cases (19.58%) of occupational pneumoconiosis and 2674 cases (80.42%) of clinically diagnosed pneumoconiosis. The measurement data were expressed by x±s. The comparison between groups was performed by independent sample t test and one-way ANOVA. Results: The age of 651 patients with occupational pneumoconiosis was 35.59-85.15 years old, the average age of onset was (54.27±8.29) years, and the average exposure to dust was (14.74±8.60) years. 2 674 cases of clinically diagnosed pneumoconiosis were 26.85~87.02 years old. The average age of onset was (55.26±7.38) years, and the average exposure time was (18.83±9.35) years. Compared with silicosis patients, coal workers' pneumoconiosis patients had longer exposure time, the difference was statistically significant (P<0.05) , and the difference was statistically significant (F=3.678, P<0.05) . There were no complications in 651 cases of occupational pneumoconiosis. Among 2 674 cases of clinically diagnosed pneumoconiosis, 710 cases (26.55%) had complications. Conclusion: Further attention should be paid to the clinical diagnosis of pneumoconiosis in Hunan Province.

RESUMO

Objective: To investigate the characteristics of pulmonary function changes and its possible influencing factors in patients with pneumoconiosis. Methods: In December 2019, pneumoconiosis patients hospitalized in four departments of occupational diseases in Hunan Occupational Disease Prevention and Control Hospital from December 2015 to December 2016 were selected as subjects. Lung function including forced vital capacity (FVC) , FVC%, forced expiratory volume in one second (FEV1) , FEV1%, forced expiratory volume in one second / forced vital capacity (FEV1/FVC) , diffusion capacity of the lung foe carbon monoxide% (DLCO%) 、maximal expiratory rlow 75% (MEF75%) , maximal expiratory rlow 50% (MEF50%) and maximal expiratory rlow 25% (MEF25%) were tested, and collect their age, occupation history, smoking history and Chronic Obstructive Pulmonary Disease Self Rating Questionnaire (CAT) score. They were followed up after 3 years to analyze the 3-year decline rates of lung function indicators and their relationship with stage of pneumoconiosis, age, smoking index, baseline values of lung function and CAT score. Results: 265 cases were studied effectively. After 3 years, the values of 9 lung function indicators of pneumoconiosis patients were significantly lower than those of 3 years ago (P<0.05) . The decline rates of FEV1%, FEV1/FVC, MEF75%, MEF50% and MEF25% were positively correlated with the stage of pneumoconiosis (r=0.250, 0.290, 0.219, 0.280, 0.141, P<0.05) . The decline rates of FEV1% and MEF75% were positively correlated with smoking index (r=0.148, 0.152, P<0.05) . The decline rates of DLCO% and MEF25% were positively correlated with the baseline value of initial pulmonary function (r=0.276, 0.153, P<0.05) , while the decline rates of FEV1%, FEV1/FVC and MEF50% were negatively correlated with the baseline values of initial pulmonary function (r=-0.215, -0.146, -0.214, P<0.05) . The decline rates of FVC%, FEV1%, MEF75% and MEF50% were positively correlated with the changes of CAT scores (r=0.147, 0.208, 0.210, 0.196, P<0.05) . Logistic regression analysis showed that old age and high initial value of DLCO% were the risk factor for the decline of DLCO% (OR=1.105、1.078, P<0.05) .High smoking index was the risk factors for the decline of MEF75% (OR=1.016, P<0.05) . High stage and the increase of CAT score were the risk factors for the decline of MEF50% (OR=1.548, 1.162, P<0.05) . High initial value of MEF25% was the risk factor for the decline of MEF25% (OR=1.010, P<0.05) . Conclusion: The pulmonary function index of pneumoconiosis patients declined significantly in 3 years. The stage of pneumoconiosis, age, smoking index and degree of pulmonary function damage were related to the decline rate of pulmonary function.

RESUMO

Objective: To investigate the compliance of inhalation during stable phase of pneumoconiosis complicated with COPD and to explore the factors influencing compliance. Methods: The patients with pneumoconiosis complicated with COPD who were hospitalized in the four Department of occupational disease prevention and treatment in Hunan province from December 2016 to August 2017 were selected as the research subjects. The examination of Chest radiograph, HRCT and lung function was perfected, and CAT score and MRC score were carried out. The age, culture, smoking history, acute aggravation of 1 years, medical insurance and so on were collected, and follow-up was conducted after 6 months. Results: Of the 115 patients who had successfully followed up, 14 cases (12.17%) were persisted in medication, and 101 cases (87.83%) did not adhere to the medication. The smoking index median of the non adherence group was 30 (15, 40) , while that of the adherence group was 16 (6, 31) . The smoking index of the adherence group was lower than that of the non adherence group. The FEV1% in the unadhered group was 44.69+15.48, and the drug group was 37.12+16.98, the FEV(1)/FVC in the unadhered group was 52.43+9.19, and the drug group was 44.43+11.88, and the lung function of the drug group was worse than that of the unadhered group. The adherence rate of group COPD (group D) was higher than that of group A, B and C, and the difference between D group and B group was statistically significant. The adherence rate of pneumoconiosis stage Ⅲ was higher than that of pneumoconiosis stageⅡand pneumoconiosisⅠ. Conclusion: The compliance of long acting bronchodilator inhalation is low in stable phase of pneumoconiosis complicated with COPD. The poorer the lung function, the higher the compliance of inhalation. The compliance of pneumoconiosis patients with Medical insurance for industrial injury is higher than that of pneumoconiosis patients with New rural cooperative medical service.

RESUMO

Objective: To investigate the safety and influencing factors of ct-guided percutaneous lung biopsy in pneumoconiosis patients. Methods: The data of 63 patients with pneumoconiosis who underwent ct-guided percutaneous lung biopsy in our hospital were studied to analyze the incidence of complications and influencing factors of percutaneous lung biopsy. Results: 63 cases of pneumoconiosis patients received CT guided percutaneous lung biopsy. There were 29 cases of complications (46.03%) , including 20 pneumothorax (37.75%) , 12 bleeding (19.05%) , and 3 cases of liquid pneumothorax (4.76%) . The single factor chi square analysis showed that there were significant differences in age, depth of focus, puncture position and puncture times (P<0.05) , and there was significant difference between the occurrence of hemorrhage and age, type of focus, size of focus, and the location of puncture site (P<0.05) . The unconditional LogisticL multiple factor regression analysis showed that the depth of the lesion was an independent risk factor for concurrency pneumothorax, and the size of the lesion was an independent risk factor for bleeding. Conclusion: Complications of CT-guided percutaneous pulmonary biopsy are mainly pneumothorax and hemorrhage. Age, focus type, focus size, focus depth, puncture site, and puncture times are all the factors of complications.

RESUMO

Objective: To investigate the change in peripheral nervous conduction velocity in patients with occupational chronic mercury poisoning and related influencing factors. Methods: From February 2011 to December 2014, urinary mercury examination and neural electromyography were performed for 104 patients with occupational chronic mercury poisoning. The data on age, type of work, working years of mercury exposure, and past medical history were collected, and peripheral nervous conduction velocity and its correlation with age, working years of mercury exposure, and urinary mercury concentration were analyzed. Results: All the 104 patients with occupational chronic mercury poisoning had a mean of 45.37±9.82 years, median (P(25), P(75)) working years of 7 (3, 11) , and a median (P(25), P(75)) urinary mercury concentration of 88.50 (56.25, 163.03) µg/g Cr. The major clinical manifestations of peripheral nerve injuries were numbness of extremities (20.2%) , hypopselaphesia/hypalgesia or hyperpselaphesia/hyperalgesia (9.6%) , and bone/muscle pain in the extremities (6.7%) . Neural electromyography showed an increase in denervation potential (fibrillation potential or positive sharp wave) and a detection rate of abnormal peripheral nervous conduction velocity as high as 65.4%. The patients with an older age and more working years had a higher incidence rate of abnormal sensory conduction velocity of the ulnar nerve. There were significant reductions in motor and sensory conduction velocities of the median nerve, motor and sensory conduction velocities of the ulnar nerve, motor conduction velocity of the common peroneal nerve, and the sensory conduction velocity of the superficial peroneal nerve (P<0.05) , with the increase in urinary mercury concentration. Conclusion: Patients with occupational mercury poisoning have a high rate of abnormal neural electromyographic findings, which can be used as an important method for early identification of chronic peripheral nerve injuries induced by mercury poisoning. The degree of peripheral nerve injuries increases with the increasing time of mercury exposure and urinary mercury concentration.

RESUMO

OBJECTIVE: Lung cancer is the leading cause of cancer-related mortality. Over 80% of all lung cancer cases are non-small-cell lung cancer (NSCLC) and approximately 5% of NSCLC patients are positive for anaplastic lymphoma kinase (ALK) gene rearrangement or fusion with echinoderm microtubule-associated protein-like 4 (EML4). NSCLC patients with positive ALK-EML4 gene fusion are highly sensitive to ALK-inhibitors. While the efficacy of the ALK-inhibitors in the treatment of NSCLC has been consistently reported, a limited number of randomized, large-scale clinical trials have been reported. The current study was, therefore, designed to systematically review and appraise current knowledge and conduct a meta-analysis on phase I, II, and III clinical trials in which ALK-inhibitors were used to treat NSCLC. MATERIALS AND METHODS: The PubMed online database was thoroughly searched. A total of 26 articles were included in a qualitative systematic review, and four of them were used to conduct the quantitative meta-analysis. RESULTS: We found that ALK inhibitors significantly improved the overall survival (OS) and progress free survival (PFS) of NSCLC patients, especially of ALK or ROS1 gene fusion-positive cases. ALK inhibitors contributed to better therapeutic outcomes regarding increased one-year and two-year OS, PFS, and ORR (Odds ratio: 4.393, 95% CI: 3.302-5.845, p < 0.001). Visual disturbance was the most common side effect observed in the patients treated with crizotinib, whereas mild gastrointestinal reactions, such as diarrhea and nausea, were most frequent in the patients treated with the 2nd generation of ALK inhibitors. CONCLUSIONS: ALK inhibitors are safe and effective in the treatment of NSCLC patients, especially those with positive ALK-EML4 gene fusion or rearrangement.

RESUMO

Objective: To investigate the clinical features of pneumoconiosis complicated with pulmo-nary emphysema. Methods: selected 868 patients with pneumoconiosis were selected from December 2015 to December 2016 in Hunan occupational disease prevention and treatment hospital. Collected the results of high-resolution spiral CT, arterial blood gas, ECG, pulmonary function and MRC score. The subjects were divided into pneumoconiosis complicated with pulmonary emphysema group and simple pneumoconiosis group accord-ing to the results of HRCT. The smoking, MRC score, pulmonary function, blood gas and complications were compared. Results: A total of 868 patients were enrolled in the study. Emphysema 232 people, accounting for 26.73%. The incidence of emphysema in the first phase of pneumoconiosis was 12.69%, and the incidence rate of emphysema in pneumoconiosis was 17.03%, The incidence of three Stage pneumoconiosis was highest, up to 60.76%, the incidence of emphysema increased with the increase of stages of pneumoconiosis (P=0.000) .The smoking index of pneumoconiosis combined with emphysema group was significantly higher than that of simple pneumoconiosis group (P<0.01) . The MRC score of pneumoconiosis complicated with pulmonary em-physema group was higher than that of simple pneumoconiosis group (P=0.000) . In pneumoconiosis complicat-ed with pulmonary emphysema group the FEV(1.0)%, FVC%, FEV(1.0)/FVC, DLCO%, oxygen partial pressure were significantly lower than that of simple pneumoconiosis group (P≤0.05) . The combined rate of Bullae of lung in pneumoconiosis complicated with pulmonary emphysema group was higher than that of simple pneumo-coniosis group (P<0.01) . Conclusion: pneumoconiosis stage and smoking. Patients with pneumoconiosis com-plicated with pulmonary emphysema had heavier breathing difficulties, more serious pulmonary function and active endurance, the degree of hypoxia is more serious, and had a higher incidence of complications. The pul-monary function of pneumoconiosis complicated with pulmonary emphysema is not consistent with the typical CPFE.
