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.

Paradoxical herniation (PH) is a rare complication after decompressive craniectomy, which manifests as that intracranial contents collapse due to atmospheric pressure higher than intracranial pressure and gravity after decompression, and the brain parenchyma eventually herniates through the tentorial notch or the foramen magnum. Contrary to the traditional treatment of cerebral hernia, the intracranial pressure in PH patients should be increased by early cranioplasty or other measures. This article reviews the clinical manifestations, mechanism, diagnoses and treatments of PH, and provides further reference for clinical work.

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.

The responsive patterns of phytochrome gene family members to photoperiod and abiotic stresses were comparatively analyzed and the favorable natural variation sites of these genes were identified. This would help understand the mechanism of phytochrome gene family in photoperiod-regulated growth and development and abiotic stress response. In addition, it may facilitate the molecular marker assisted selection of key traits in foxtail millet. In this study, we used RT-PCR to clone three phytochrome genes SiPHYA, SiPHYB and SiPHYC from ultra-late maturity millet landrace variety 'Maosu'. After primary bioinformatics analysis, we studied the photoperiod control mode and the characteristics of these genes in responding to five abiotic stresses including polyethylene glycol (PEG)-simulated drought, natural drought, abscisic acid (ABA), high temperature and NaCl by fluorescence quantitative PCR. Finally, we detected the mutation sites of the three genes among 160 foxtail millet materials and performed haplotype analysis to determine the genes' functional effect. We found that the cloned cDNA sequences of gene SiPHYA, SiPHYB and SiPHYC were 3 981, 3 953 and 3 764 bp respectively, which contained complete coding regions. Gene SiPHYB and SiPHYC showed closer evolutionary relationship. Photoperiod regulated all of the three genes, but showed more profound effects on diurnal expression pattern of SiPHYB, SiPHYC than that of SiPHYA. Under short-day, when near heading, the expression levels of SiPHYA and SiPHYB were significantly lower than that under long-day, indicating their roles in suppressing heading of foxtail millet under long-day. SiPHYB and SiPHYC were responsive to PEG-simulated drought, natural drought, ABA and high temperature stresses together. SiPHYA and SiPHYB responded differently to salt stress, whereas SiPHYC did not respond to salt stress. Re-sequencing of 160 foxtail millet materials revealed that SiPHYB was highly conservative. Two missense mutations of SiPHYA, such as single nucleotide polymorphism (SNP) 7 034 522^C→T and SNP7 036 657^G→C, led to delaying heading and increasing plant height. One missense mutation of SiPHYC, such as SNP5 414 823^G→T, led to shortening heading under short-day and delaying heading under long-day, as well as increasing plant height and panicle length regardless of photo-thermal conditions. Photoperiod showed different regulatory effects on SiPHYA, SiPHYB and SiPHYC. SiPHYB and SiPHYC jointly responded to various abiotic stresses except for the salt stress. Compared with the reference genotype, mutation genotypes of SiPHYA and SiPHYC delayed heading and increased plant height and panicle length.
