Objective To explore the effects of psychological intervention on negative emotion and quality of life of the patients with chronic obstructive pulmonary disease (COPD). Methods A total of 80 patients with COPD were divided into the psychological intervention group and the control group. The psychological intervention group received routine treatment + psychological intervention; the control group only received routine treatment. SCL-90 symptom checklist and St George'S Respiratory Questionnaire (SGRQ) scores before and after the treatment were assessed. Results There was no significant difference in each score between the 2 groups at baseline ( P ＞ 0. 05 ). After 3 months' treatment, the scores of the 2 groups was declined; somatization, obsession, anxiety, and depression were significantly improved compared with baseline. There was no significant difference in SGRQ respiratory symptoms, disease impact and the SGRQ indicators at baseline ( P ＞ 0. 05 ). After the invention, there showed significant difference in the treatment group in SGRQ respiratory symptoms, disease impact and the SGRQ indicators compared with baseline (P ＜0. 05 ). Conclusion Psychological intervention could improve negative mood and the quality of life of patients with COPD.

BACKGROUND AND OBJECTIVETransient receptor potential canonical (TRPC) proteins, a group of Ca2' permeable nonselective cation channels, are thought to constitute store-operated calcium channels (SOCC) and mediate store-operated calcium entry (SOCE) in various cell types. Members of TRPC have been found to be involved in abnormal proliferation, differentiation, and growth of cancer cells. The aim of this study is to detect the mRNA and protein expression of TRPC in non-small cell lung cancer (NSCLC).

METHODSReal-time quantitative PCRwas performed to screen the expression of TRPC mRNA in NSCLC tissue. Protein expression of TRPC was detected by Western blot.

RESULTSAmong the seven family members of TRPC so far identified (TRPC1-7), we detected the expression ofTRPC1, TRPC3, TRPC4, TRPC6 mRNA in 24 cases of NSCLC tissue; TRPC2, TRPC5 and TRPC7 mRNA were not detectable. The relative abundance of the expressed TRPC was TRPC1 approximately equal TRPC6 > TRPC3 > TRPC4. Western blot confirmed the protein expression of TRPC1, TRPC3, TRPC4 and TRPC6 in NSCLC tissue.

CONCLUSIONOut of the seven members of TRPC, we found TRPC1, TRPC3, TRPC4, TRPC6 mRNA and protein were selectively expressed in human NSCLC tissue. This study could provide a basis for future exploration of the individual role of these TRPC proteins in mediating SOCE and in the progression of lung cancer.

A farm worker in Baodi District of Tianjin was diagnosed with Tsutsugamushi disease due to fever and intermittent cough for more than 3 months.The patient's diagnosis and treatment process was complicated, and the diagnosis was delayed in the early stage of the disease because the clinician neglected the occupational history and lacked knowledge about the prevention and control of tsutsugamushi disease. As an important part of the epidemiological history, occupational history is crucial for the diagnosis of occupational related diseases. Clinical thinking runs through the whole process of clinical diagnosis and disease treatment, and correct clinical thinking can effectively reduce the occurrence of misdiagnosis.Clinicians should ask and record career history in detail to improve the quality of health care.

Objective:To explore the relationship between microRNA-4429 (miR-4429) derived from serum exosomes and prognosis of radical radiation and chemotherapy for non-small cell lung cancer (NSCLC).Methods:309 blood samples of NSCLC patients were collected [before chemotherapy (T0), after 1 cycle of chemotherapy (T1) and after 2 cycles of chemotherapy (T2), 103 cases at each time point], and the expression level of miR-4429 was detected by real-time fluorescent quantitative PCR method, and the relationship between it and the prognosis of radical radiation and chemotherapy in NSCLC was analyzed.Results:The 1-year, 2-year and 3-year survival rates of 103 NSCLC patients were 69.90%, 45.63% and 34.95%, respectively. The expression levels of T1-miR-4429 and T2-miR-4429 in the survival group were 0.66±0.14 and 0.77±0.11, respectively, which were higher than T1-miR-4429 (0.60±0.06) and T2-miR-4429 (0.62±0.11) in the death group, and the differences were statistically significant ( t=2.269, 6.997, P<0.05). Restricted cubic spline fitting COX regression analysis showed that T2-miR-4429 had a linear relationship with survival in NSCLC. COX regression analysis showed that TNM staging was an independent risk factor for the survival and prognosis in NSCLC ( P<0.05), and the degree of differentiation, targeted therapy and T2-miR-4429 were all independent protective factors for the survival and prognosis in NSCLC ( P<0.05). The calibration curve of the nomogram regression model constructed by TNM stage, degree of differentiation, targeted therapy and T2-miR-4429 coincided well with the ideal curve, and the C-index was 0.713. Conclusions:The high expression level of T2-miR-4429 indicates that NSCLC patients have a low risk of poor survival prognosis. The nomogram regression model constructed by TNM staging, degree of differentiation, targeted therapy and T2-miR-4429 has a certain degree of discrimination and accuracy, which can assist in evaluating the prognosis of NSCLC.

Objective To study the value of postmortem imaging on the diagnosis of intestinal perforation.Method Postmortem imaging(PMCT and PMCTA)data of 2 intestinal perforation deaths(and 4 controlled cases)were reviewed retrospectively.Diagnosing capacities of intestinal perforation by postmortem imaging method were further investigated.Results PMCT is sensitive in detecting the free air and liquid induced by intestinal perforation.PMCT can sometimes detect the gravity-dependent purulent secretions in the abdominopelvic cavity.PMCTA can visualize the extravasation of contrast agent from the perforation,which can be used to locate the accurate perforation region.Conclusion Postmortem imaging method(PMCT and PMCTA)is an important tool for the diagnosis of intestinal perforation,which can not only be used as a forensic diagnosis method,but is also useful to locate the perforation site before an forensic autopsy.

Objective Through a multi-software visual analysis of the literature on the influence of T cells on rheumatoid arthritis(RA)in recent ten years,the research hotspot and frontier development in this field were summarized.Methods The Chinese and English literature on the influence of T cells on RA from 2012 to 2022 years was retrieved from CNKI and Web of Science database as the research object.CiteSpace and VOSviewer software were used to analyze the number of publications,authors and keywords.Results 519 articles in Chinese and 861 in English were retrieved.The results showed that the number of articles in Chinese increased slowly from 2020 to 2022 years,while the overall trend in English was stable.Keyword analysis shows that it is predicted that future research in this field will focus on the pathogenesis of T cells in RA,the mechanism of bone destruction in RA,disease activity,oxidative stress.Conclusion The influence of T cells on RA has attracted much attention in the past,present and future,and has great research value.However,due to the differences in research priorities at home and abroad,the teams should interact positively and communicate with each other to reveal the internal mechanism of RA and provide theoretical basis for targeted therapy.
