One confirmed diagnosiscase of severe human infection by avian influenza H7N9 admitted to intensive care unit (ICU) of the Second Affiliated Hospital of Guizhou Medical University on January 12th, 2017 was reported. The patient was treated with the sepsis bundle, and recovered finally, including a series of comprehensive treatments, such as respiratory support, circulation support, antiviral, anti-inflammation, immunization enhancement, critical nursing, fluid management, nutritional support and treatment of complications. The critical patient was admitted on January 27th, and the treatment was successful. It has important significance to rescue the severe human infection from avian influenza H7N9 by the sepsis bundle.

Human infection with avian influenza A (H7N9) is an acute contagious respiratory disease. Acute respiratory distress syndrome (ARDS) is a common complication in patients with severe avian influenza A (H7N9), for whom mechanical ventilation (MV) is an important supportive method. A patient, suffered from severe avian influenza A (H7N9) and complicated with ARDS, was admitted to the Second Affiliated Hospital of Guizhou Medical University in January 2017. With very intensive care for oxygenation, respiration and consciousness, and monitoring, she was successfully cured by comprehensive managements, among which noninvasive mechanical ventilation (NIV) was the major respiratory support method. The result demonstrate that, in patients with conscious state, satisfied expectoration ability and relatively good cooperation, and with close observation of oxygenation and respiratory rate, NIV may be accepted as an effective method for patient with ARDS caused by severe avian influenza A (H7N9).

BACKGROUND: In recent years, a number of clinical trials have shown that immunocheckpoint inhibitors (ICI) have brought survival benefits to patients with advanced non-small cell lung cancer (NSCLC), however, such clinical trials comprise cohorts selected based on strict and complex entry and exclusion criteria, and the results cannot fully reflect the real world situation. The purpose of this study was to investigate the clinical efficacy and safety of immunotherapy in the real world, as well as possible prognostic factors. METHODS: Patients with advanced NSCLC receiving immunotherapy in Beijing Chest Hospital from January 2017 to July 2019 were retrospectively collected, and the following information were collected: curative effect, progression-free surival (PFS) and adverse reactions. The occurrence of adverse reactions and clinical curative effect and prognosis factors that may be relevant were explored. RESULTS: 34 patients were enrolled in this study, median PFS was 5.66 months (95%CI: 4.48-6.84), grade 1-2 and 3-4 incidence of adverse events was 61.71% (22/34) and 14.71% (5/34), there were 3 patients (8.82%) experienced fatal immune related adverse events (irAE), 2 cases were immune associated pneumonia, 1 case was immune related myocarditis. Univariate analysis showed that tumor-node-metastasis (TNM) stage and metastatic site were correlated with median PFS (P<0.05), and multivariate analysis showed that patients with extrapulmonary metastasis (OR=6.42, P=0.029) and pleural metastasis (OR=14.14, P=0.006) had shorter median PFS. CONCLUSIONS In the real world, immunotherapy has good efficacy in patients with advanced NSCLC, but the incidence of severe irAE is also higher. Distant metastasis and pleural metastasis are poor prognostic factors for advanced NSCLC patients receiving immunotherapy.

Aim To explore the mechanism of grape seed proanthocyanidins (GSPs) targeting astrocytes (AS), so as to regulate the phenotype and function of AS and maximize their neuroprotective effect. Methods The effects of GSPs on the phenotype, secretion of pro-inflammatory factors and neurotrophic factors of Al AS induced by TNF-α, IL-1α and Clq were investigated by RT-PCR, Elisa and Western blot in vitro. And JNK phosphorylation was determined using Western blot. Results GSPs significantly reduced the expression of C3d and Clq of Al AS markers and inhibited the phosphorylation of JNK. Moreover, compared with the model group, GSPs could significantly inhibit the release of pro-inflammatory cytokines IL-6, IL-1 α, IL-17 and H
