Development and validation of a nomogram to predict risk of septic cardiomyopathy in the intensive care unit.

The aim of this study was to develop a simple but effective nomogram to predict risk of septic cardiomyopathy (SCM) in the intensive care unit (ICU). We analyzed data from patients who were first admitted to the ICU for sepsis between 2008 and 2019 in the MIMIC-IV database, with no history of heart disease, and divided them into a training cohort and an internal validation cohort at a 7:3 ratio. SCM is defined as sepsis diagnosed in the absence of other cardiac diseases, with echocardiographic evidence of left (or right) ventricular systolic or diastolic dysfunction and a left ventricular ejection fraction (LVEF) of less than 50%.

Hemodynamic predictors of early neurological deterioration and clinical outcome after endovascular treatment in large artery occlusion.

Objective: Half of the patients with acute large artery occlusion (LAO) have poor outcomes after endovascular treatment (EVT). Early complications such as cerebral edema and symptomatic intracranial hemorrhage (sICH) can lead to early neurological deterioration (END), which correlates with hemodynamics. This study aimed to identify the hemodynamic predictors of END and outcomes in LAO patients after EVT.

[Effect of Acupuncture at "Taichong"(LR 3) and "Neiguan"(PC 6) on Blood Pressure and Contents of Aspartic Acid and Glutamic Acid in the Rostral Ventrolateral Medulla in Spontaneous Hypertension Rats].

Objective: To explore the potential mechanism of acupuncture stimulation of "Taichong" (LR 3) and "Neiguan" (PC 6) in spontaneous hypertension rats (SHR) by investigating its effects on blood pressure and contents of aspartic acid(Asp) and glutamic acid (Glu) in the rostral ventrolateral medulla (RVLM) region.

Methods: A total of 75 SHR were randomized into model group, Taichong (LR 3) group, Neiguan (PC 6) group, LR 3+non-acupoint group and LR 3 + PC 6 group (=15 rats in each group), and 15 Wistar rats of the same age were used as the normal control group. The filiform needles were inserted into the abovementioned acupoints and non-acupoint, twirled for a while and then retained for 30 min.

[Preliminary Investigation of the Amount, the Molecular Weight and the Activity of Polysaccharides from Chaenomeles Speciosa Fruits in Ethanol Fractional Precipitation].

Chaenomeles speciosa fruits were extracted using water. The extracts were precipitated with 20%~95% (φ) ethanol, respectively. The amount of total polysaccharide was measured with phenol-sulfuric acid method.

Symmetry breaking of α-[H2W12O40](6-) depends on the transformation of isopolyoxotungstates.

Two enantiotopic 1D chain compounds, [Cu3(L1)3(H2O)2(H2W12O40)]·4H2O (1a,b; L1 = 2-(4,6-bis(pyridin-2-yl)pyridin-2-yl)pyridine), crystallizing in the chiral space group P212121 were prepared and spontaneously resolved in the absence of any chiral source. Interestingly, compounds 1a,b can be prepared from a [W7O24](6-) aqueous solution, [(n-C4H9)4N]4[W10O32], or Na10[H2W12O42], but when [H2W12O40](6-) aqueous solution was the starting material, the achiral compound [CuL1]2[H4W12O40]·5H2O (2) was obtained. When a terpyridine ligand (L2) having a coordination mode similar to that of L1 was used, the mesomeric dimer [Cu3(L2)3(H2O)(H2W12O40)]2·4H2O (3) was obtained from [W7O24](6-) aqueous solution or Na10[H2W12O42], but from [H2W12O40](6-) aqueous solution only compound [Cu2(L2)2Cl2]2[W10O32] (4) was isolated.
