Investigation of the chronic respiratory symptoms and pulmonary function of adult residents in Hongtong County, Shanxi Province / 中华预防医学杂志

Objective: To investigate the chronic respiratory symptoms and pulmonary function of adult residents in 3 towns of Hongtong County, Shanxi Province, and to explore their risk factors. Methods: The investigation of chronic respiratory symptoms and lung function status of adult residents in Hongdong County is based on the regional population of the entire county in Hongdong County. The project was initiated by the Science and Technology Department of Linfen City and coordinated by the Hongdong County Government. The investigation will be conducted in 3 townships in Hongdong County, Linfen City, Shanxi Province from April to November 2021: Demographic characteristics, respiratory symptoms, smoking dust exposure and other personal history were collected through questionnaires. Physical examination, routine blood tests and lung function tests were also performed on each individual. SPSS 22.0 software was used to conduct t test, χ2 test, ANOVA or Kruskal-Wallis test for statistical analysis of the collected information. Results: 10 945 subjects aged 18-102 years were included in the analysis, of whom 3 754 (34.3%) were male, 1 222 (11.2%) had a history of dust exposure, 7 164 (65.5%) had used straw and firewood as cooking fuel, and 3 296 (30.1%) had a history of smoking. Among the participants, 394 (3.6%), 339 (3.1%), and 1 543 (14.1%) had respiratory symptoms such as chronic cough, sputum, and dyspnea. Statistics showed that the population with chronic respiratory symptoms was more elderly and had a smoking history, and the incidence of chronic respiratory symptoms was higher in those who smoked more than 40 packs a year (all P<0.05). Men with a history of dust exposure were more likely to suffer from chronic cough and expectoration, while emaciation and biofuel use for more than 40 years were more likely to suffer from chronic expectoration and dyspnea (all P<0.05). The median values of forced expiratory volume in 1 second (FEV1), forced vital capacity (FVC) and FEV1/FVC in 1 second were 2.19 L/s, 3.24 L and 69.16%, respectively. Among them, the lung function of 5 801 (53.0%) respondents was lower than the expected value. The median FEV1/FVC decreased with the increase of age. The FEV1/FVC of people over 40 years old with smoking history was lower, the dust exposure history of people with decreased lung function was more than that of people with normal lung function, and the incidence of chronic expectoration and dyspnea was higher in people with decreased lung function (all P<0.05). The absolute value and ratio of eosinophils in patients with decreased ventilation function over 60 years old were significantly higher than those with normal ventilation function, but the level of body mass index (BMI) was lower (all P<0.05). Conclusion: In Hongdong County, Shanxi Province, grassroots residents have poor medical awareness, low lung function examination rate, chronic respiratory symptoms and lung function decline are associated with more risk factors. Primary medical institutions need to formulate prevention strategies and carry out lung function detection according to the actual situation, focusing on monitoring and follow-up of high-risk groups to achieve early and timely prevention, diagnosis and treatment of chronic obstructive pulmonary disease.

Intervention effect of Feiji Recipe on immune escape of lung cancer / 中国中西医结合杂志

<p><b>OBJECTIVE</b>To evaluate the intervention effect of Feiji Recipe (FJR) on tumor immune escape.</p><p><b>METHODS</b>In the prospective randomized control study, 60 cases of middle stage and advanced non-small cell lung cancer (NSCLC) with qi-yin deficiency syndrome were randomly assigned to the treatment group and the control group, 30 in each group. The levels of CD+ CD25+ Tr, interleukin-10 (IL-10), vascular endothelial growth factor (VEGF), sCD44v6 and transforming growth factor-beta1 (TGF-beta1) of peripheral blood were observed before and after treatment, and the clinical efficacy of FJR was evaluated depending upon the changes in tumor size, Karnofsky Performance scoring (KPS) and TCM syndrome.</p><p><b>RESULTS</b>(1) The levels of CD4+ CD2+Tr, VEGF, sCD44v6, TGF-beta1, and IL-10 decreased, in the treatment group as compared with those in the control group, respectively. (2) The stabilization rate of tumor in the treatment group was superior to that in the control group (78.26% vs 50.00%, P < 0.05). (3) The stabilization rate of KPS increasing in the treatment group and the control group was 76.67% and 43.33% respectively, suggesting the improvement of KPS in the treatment group was superior to that in the control group (P < 0.01). (4) Improvement in TCM qi-yin deficiency syndrome was more significant in the treatment group than that in the control group.</p><p><b>CONCLUSION</b>FJR can stabilize the tumor body, improve the clinical symptoms of middle stage and advanced NSCLC with qi-yin deficiency syndrome, promote patients' quality of life, and is effective in recovering immuno-surveillance and intervening immune escape of lung cancer through multi-pathway to enhance the clinical therapeutic efficacy.</p>

Evaluation on effect of feiji recipe on quality of life of patients with non-small cell lung cancer by adopting international questionnaire of QOL / 中国中西医结合杂志

<p><b>OBJECTIVE</b>To evaluate the effect of Feiji Recipe (FJR) on quality of life (QOL) of patients with non-small cell lung cancer (NSCLC).</p><p><b>METHODS</b>One hundred and two patients with NSCLC were randomly assigned into 2 groups. The 61 patients in the combined treated group were given FJR and chemotherapy and the 41 patients in the control group were treated with chemotherapy alone. They were observed for two treatment courses with QOL estimated by EORTC QLQ-C43 questionnaire and FACT-L questionnaire, the two international questionnaires as the tools for measurement, and referred to the traditional evaluating indexes of clinical efficiency.</p><p><b>RESULTS</b>QOL in the combined treated group was improved after treatment with the improvement of scores in all domains, including functional and symptom sub-domain, while it in the control group deprived significantly, showing significant difference between the two groups (P < 0.05). Similar results were also shown in the evaluation of physical performance by Eastern Cooperative Oncology Group (ECOG) and Karnovfsky performance scoring. The gastrointestinal reaction and myelo-suppression were slighter in the combined treated group than those in the control group (P < 0.05), and no significant difference was shown between the response rate of the two groups (P > 0.05).</p><p><b>CONCLUSION</b>FJR can improve QOL of patients with NSCLC, reduce the adverse reaction of chemotherapy, and improve patients' physical performance.</p>

Study on the relationship among the international scales for quality of life evaluation in patients with lung cancer, the East Cooperative Oncology Group Status and Lung Cancer Symptoms Lists of TCM / 中国中西医结合杂志

<p><b>OBJECTIVE</b>To investigate the relationship among international scales for quality of life (QOL), physical performance assessment and Lung Cancer Symptoms Lists of Traditional Chinese Medicine (LCSL) from the viewpoint of clinical observation.</p><p><b>METHODS</b>QOL of 363 patients with lung cancer was estimated with two international scales, the European Organization for Research and Treatment of Cancer QOL Questionnaire LC-43 (EORTC QLQ-LC43) and the Functional Assessment of Cancer Therapy General and Lung (FACT-L). In the same time, scores calculated by Karnofsky Performance Status (KPS), East Cooperative Oncology Group Status (ECOG) and LCSL were recorded. Correlation and consistency among them were analyzed.</p><p><b>RESULTS</b>EORTC QLQ-C43, FACT-L were correlated with KPS, ECOG and LCSL, but the correlation coefficient was small. All these indexes were consistent.</p><p><b>CONCLUSION</b>QOL should be assessed by QOL questionnaire, not by physical performance indexes, although they can be the simply forecast indexes of QOL. There is certain consistency between LCSL, QOL and physical performance.</p>
