Objective To investigate the effect of long non-coding RNA F19 (lncRNA F19) on secondary brain injury following traumatic brain injury (TBI) in mice. Methods (1) A total of 96 C57BL/6J male wild-type mice were divided into sham group, sham+control lentivirus group, sham+F19 lentivirus group, TBI group, TBI+control lentivirus group and TBI+F19 lentivirus group according to the random number table. Each group consisted of two subgroups of 1 day and 3 days after TBI, with eight mice per subgroup. The expression and silence efficiency of lncRNA F19 were detected. ( 2 ) A total of 96 C57BL/6J male wild-type mice were divided into sham group, TBI+control lentivirus group and TBI + F19 lentivirus group according to the random number table. Each group consisted of two subgroups of 1 day and 3 days after TBI, with 16 mice per subgroup. The effect of lncRNA F19 on neuronal apoptosis after TBI was recorded. The mice TBI model was established using the controlled cortical damage method (CCI). The lncRNA F19 lentivirus or control lentivirus were administrated by intracerebroventricular injection 5 days before injury. The expressions of lncRNA F19 ( 2 -ΔΔct ) were detected by real-time quantitative PCR ( qRT-PCR ) at 1 day and 3 days after injury. The Toll-like receptor 4 (TLR4), B lymphocyte tumor-2 (Bcl-2) and Bcl-2 related protein (Bax) expressions were detected by Western blot. The TUNEL was used to detect apoptosis around the traumatic lesions. Results From the first day after injury, both in the sham operation and TBI groups, the control lentivirus had no effect on the level of lncRAN F19 (P >0. 05). One day after injury, compared with sham +control lentivirus group, the levels of lncRNA F19 in sham + F19 lentivirus group were significantly decreased (0. 07 ± 0. 07:0. 93 ± 0. 17);compared with TBI+control lentivirus group, levels of lncRNA F19 in TBI+F19 lentivirus group were significantly decreased (2. 91 ± 1. 18:0. 52 ± 0. 32) (P<0. 05). There were significantly lower protein levels of TLR4 (0. 51 ± 0. 13:0. 66 ± 0. 15), Bax (0. 45 ± 0. 06:0. 67 ± 0. 16), lower TUNEL-positive neurons ratio [(23. 55 ± 6. 85)％ : (31. 58 ± 7. 52)％], but higher protein levels of Bcl-2 (0. 76 ± 0. 16:0. 47 ± 0. 12) in TBI+F19 lentivirus group compared with the TBI+ control lentivirus group (P <0.05). Three days after injury, compared with sham + control lentivirus group, levels of lncRNA F19 in sham+F19 lentivirus group were significantly decreased (0. 11 ± 0. 09:0. 96 ± 0. 09); compared with TBI+control lentivirus group, levels of lncRNA F19 in TBI+F19 lentivirus group were significantly decreased (0. 54 ± 0. 24:3. 39 ± 0. 90) (P <0. 05). There were significantly lower protein levels of TLR4 (0. 60 ± 0. 20):(0. 85 ± 0. 09)], lower Bax (0. 60 ± 0. 12:0. 88 ±0. 21), lower TUNEL-positive neurons ratio [(29. 10 ± 7. 37)％ :(39. 22 ± 10. 64)％], but higher protein levels of Bcl-2 (0. 66 ± 0. 12:0. 35 ± 0. 16) in TBI+F19 lentivirus group compared with the TBI+control lentivirus group (P<0. 05). Conclusion Inhibition of lncRNA F19 can significantly reduce the TLR4-induced neuronal apoptosis in cortex after TBI in mice and alleviate reduce the secondary brain injury.

Objective:To investigate the factors affecting the application of systemic glucocorticoids in patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD) with carbon dioxide (CO 2) retention, and to guide the formulation of a strategy to reduce systemic glucocorticoid exposure. Methods:The AECOPD patients with CO 2 retention admitted to the Ningde Municipal Hospital of Fujian Medical University from January 2017 to December 2019 were enrolled. The general information, past history, times of acute exacerbations within 1 year, pneumonia on admission, causes of COPD, heart failure, blood gas analysis, eosinophil count (EOS), albumin (Alb) and apolipoprotein E (ApoE) levels, exhaled nitric oxide (FeNO) level, inhaled glucocorticoid and non-invasive mechanical ventilation treatment at acute exacerbation were collected. The patients were divided into recommended dosage group (exposure levels in the recommended dosage range, cumulative prednisone dosage ≤ 200 mg) and exceeded group (exposure levels exceeded the recommended dose, cumulative prednisone dosage > 200 mg) according to cumulative systemic glucocorticoid exposure dosage of the patients during hospitalization. The clinical data of patients between the two groups were compared, and possible factors with P < 0.1 in univariate analysis were included in multivariate Logistic regression analysis to screen the related factors of systemic glucocorticoid exposure level in AECOPD patients with CO 2 retention. Results:According to the order of hospitalization, 151 AECOPD patients with CO 2 retention were enrolled, 8 patients were excluded, and 143 patients were enrolled in the analysis. Of the 143 patients, 68 received the recommended dose of systemic glucocorticoid, and 75 received excessive systemic glucocorticoid. Age, percentage of forced expiratory volume in 1 second (FEV1%) at stable phase, frequency of acute exacerbation within 1 year, heart failure ratio, oxygen index (PaO 2/FiO 2), arterial partial pressure of carbon dioxide (PaCO 2), serum EOS and ApoE levels at admission, the ratio of aerosolized inhaled glucocorticoids and non-invasive mechanical ventilation showed statistical differences between the two groups. Multivariate Logistic regression analysis showed that related factors affecting systemic glucocorticoid exposure levels of AECOPD patients with CO 2 retention were FEV1% at stable phase [odds ratio ( OR) = 0.957, 95% confidence interval (95% CI) was 0.921-0.994, P = 0.023], acute exacerbation frequency within 1 year ( OR = 1.530, 95% CI was 1.121-2.088, P = 0.007), heart failure ( OR = 3.022, 95% CI was 1.263-7.231, P = 0.013), PaCO 2 ( OR = 1.062, 95% CI was 1.010-1.115, P = 0.018) and EOS at admission ( OR = 0.103, 95% CI was 0.016-0.684, P = 0.019), aerosolized inhaled glucocorticoids ( OR = 0.337, 95% CI was 0.145-0.783, P = 0.011) and non-invasive mechanical ventilation at acute exacerbation ( OR = 0.422, 95% CI was 0.188-0.948, P = 0.037), of which high FEV1% at stable phase, high EOS at admission, aerosolized inhaled glucocorticoid and non-invasive mechanical ventilation at acute exacerbation were protective factors, while high frequency of acute exacerbation within 1 year, heart failure and high PaCO 2 were risk factors. Conclusions:For AECOPD patients with CO 2 retention, high FEV1% at stable phase, high EOS level at admission, aerosolized inhaled glucocorticoid and non-invasive mechanical ventilation at acute exacerbation can reduce systemic glucocorticoid exposure. In addition, high frequency of acute exacerbation within 1 year, heart failure, and high PaCO 2 can increase systemic glucocorticoid exposure.

We conducted a prospective study to assess the non-inferiority of adjuvant chemotherapy alone versus adjuvant concurrent chemoradiotherapy (CCRT) as an alternative strategy for patients with early-stage (FIGO 2009 stage IB-IIA) cervical cancer having risk factors after surgery. The condition was assessed in terms of prognosis, adverse effects, and quality of life. This randomized trial involved nine centers across China. Eligible patients were randomized to receive adjuvant chemotherapy or CCRT after surgery. The primary end-point was progression-free survival (PFS). From December 2012 to December 2014, 337 patients were subjected to randomization. Final analysis included 329 patients, including 165 in the adjuvant chemotherapy group and 164 in the adjuvant CCRT group. The median follow-up was 72.1 months. The three-year PFS rates were both 91.9%, and the five-year OS was 90.6% versus 90.0% in adjuvant chemotherapy and CCRT groups, respectively. No significant differences were observed in the PFS or OS between groups. The adjusted HR for PFS was 0.854 (95% confidence interval 0.415-1.757; P = 0.667) favoring adjuvant chemotherapy, excluding the predefined non-inferiority boundary of 1.9. The chemotherapy group showed a tendency toward good quality of life. In comparison with post-operative adjuvant CCRT, adjuvant chemotherapy treatment showed non-inferior efficacy in patients with early-stage cervical cancer having pathological risk factors. Adjuvant chemotherapy alone is a favorable alternative post-operative treatment.
