The optimal clinical treatment and the computed tomography (CT) morphological characteristics of posterior malleolar fractures (PMF) with talar subluxation remain inconclusive. Clinically, both plate screws and lag screws are widely used to fix posterior malleolar fragments using a direct or indirect approach. We sought to summarize the morphological characteristics and modified classification on the basis of CT and the intraoperative strategy for posterior talar subluxation in PMF. ⋯ According to the injury mechanism and the morphological characteristics of the fractures, the proposed improved classification system for PMF with subluxation of the talus based on the injury mechanism and the fracture morphology can provide guidance for surgical management strategies and achieve optimal outcomes.

A meta-analysis of the studies involving Sacubitril/Valsartan in chronic heart failure was performed to compare the efficacy and safety of Sacubitril/Valsartan with traditional drug therapy in chronic heart failure. ⋯ Compared with traditional drugs, Sacubitril/Valsartan significantly improved echocardiography, vital signs and biomarkers of patients with chronic heart failure, and reduced the incidence of hyperkalemia, renal dysfunction and other adverse reactions. Further large sample trials are needed in the future to determine the long-term effects of Sacubitril/Valsartan on efficacy and safety in patients with chronic heart failure.

Neuroinflammation is the most common cause of neurological diseases. Exosomes derived from mesenchymal stem cells (MSCs-exos) have been reported to reduce inflammation and neuronal injury. Its underlying mechanism remains poorly unknown. ⋯ Moreover, H19 functioned as a sponge for miR-29b-3p. miR-29b-3p mimics abolished the effects of BMSCs-exosomal H19 on M1/M2 polarization and inflammation in LPS-stimulated BV-2 cells. The neuroprotective function of BMSCs-exosomal H19 was attenuated by miR-29b-3p mimics in LPS-stimulated HT22 cells. BMSCs-exosomal H19 modulates LPS-stimulated microglial M1/M2 polarization and alleviates inflammation-mediated neurotoxicity by sponging miR-29b-3p.

To explore the effects of cardiopulmonary exercise testing (CPET) on the cardiopulmonary function, the exercise endurance, and the NT-proBNP and hscTnT levels in chronic heart failure (CHF) patients. ⋯ CPET for patients with CHF helps increase heart and lung function, improves exercise endurance, reduces the NT-proBNP and hscTnT levels, and improves patients' quality of life.

To explore the application value of goal-directed fluid therapy (GDFT) in the enhanced recovery after surgery (ERAS) of patients undergoing radical lung cancer surgery (RLCS). ⋯ GDFT is beneficial to the rapid recovery of patients after RLCS, because it can exert a positive effect on maintaining the stability of hemodynamic indexes and reducing inflammation and postoperative complications.
