ObjectiveTo study the effect of adaptive group psychological training on mental quality and emotion of soldiers.MethodsA total of 48 soldiers ( experiment group) received group psychological training and read a textbook,Mental Quality Training for soldiers,for 3 months,and the other 45 soldiers served as control group.Armyman mental quality inventory (AMQI),self-rating depression scale (SDS) and state-trait anxiety inventory(STAI) were employed to evaluate the mental quality and emotion of soldiers before and after training.All data were analyzed by paired-sample t test.Results ①As compared with pre-training,the AMQI scores of training group increased significantly in bravery ( 71.50 ± 9.59 ),self-confidence ( 68.24 ± 8.36 ),aptitude ( 74.54 ± 10.81 ),loyalty(75.29 ± 8.08 ) and general score ( 359.07 ± 20.30 ) (P ＜ 0.05,P ＜ 0.01 ) ; and no significant difference were found in those of control group(P ＞ 0.05 ).②When compared with pre-training,the scores of SDS (39.00 ±8.38),SAI(40.14 ±9.92),TAI(41.16 ±7.47) and STAI(81.30 ± 12.52) of training group decreased significantly (P ＜ 0.05,P＜ 0.01 ) ; and no significant difference was found in those of control group(P ＞0.05 ).ConclusionGroup psychological training can improve mental quality of soldiers,which is helpful to relax anxiety and depression of soldiers.

Objective: To investigate the anti-inflammatory effect of hesperetin (HSP) on lung damage induced by paraquat (PQ) in rats by detecting the levels of inflammatory makers in rat lung tissues. Methods: 140 Wistar male rats were randomly divided into negative control group, HSP control group, HSP control group, paraquat model group, pirfenidone (PDF) positive control group, and 100, 200, 400 mg/kg HSP treatment groups. All groups were exposed to 50mg/kg paraquat by oral gavage except for the negative control group and HSP control group. After 24 hours, the rats in each group were given drug intervention once daily. 10 rats were randomly sacrificed at 7th day and 28th day after exposure to paraquat respectively. 3 rats were randomly selected from them and HE, Masson staining were used to observe the pathological changes in the lungs of each group. Each group randomly selected 6 rats at two time points to detect the levels of TGF-β₁, TNF-α, IL-4, IL-10, IL-1β and IFN-γ in rat lung tissues. Results: Histopathological examination found that the lung injury were reduced in the rats of PDF positive control group and all HSP treatment groups. Compared with the negative control group, the levels of TGF-β1, IL-1β, TNF-α, IL-4, and IL-10 in rat lung tissues were significantly increased (P<0.05, P<0.01) after PQ exposure at two points in time, and there was no significant difference in the level of IFN-γ in lung tissues compared with the negative control group (P>0.05) . The levels of TGF-β1, IL-1β, IL-4, IL-10 and TNF-α in the lung tissues of rats on the 7th day in different dose treatment groups of HSP were reduced compared with those in the PQ model group with varying degrees (P<0.05, P<0.01) . The level of IFN-γ in lung tissues of rats were not significantly different from that of model group (P>0.05) . The levels of TGF-β₁ and TNF-α in lung tissue of rats on the 28th day in PDF positive control group and different dose treatment groups of HSP were reduced compared with those in the PQ model group with varying degrees (P<0.05, P<0.01). The levels of IFN-γ in the rat lung tissues were increased compared with those in the PQ model group (P<0.05). Besides, there were no significant in the levels of IL-1β, IL-4 and IL-10 in lung tissues compared with PQ model group (P>0.05). Conclusion HSP can reduce lung damage induced by PQ in rats by inhibiting the release of inflammatory factors and promoting the secretion of anti-inflammatory factors.

Aim To explore the regulatory effect of Danggui-chuanxiong herb pair (GX) on JAK-STAT signaling pathway in rats with cerebral ischemia/reper-fusion injury (I/R). Methods The I/R injury rat model was constructed by modified suture occlusion method. After 24 hours of perfusion, Zea Longa scoring method was used to score the neurological function, TTC staining to detect the cerebral infarct volume of rats, HE staining to observe the pathological changes of brain tissues, the biochemical method to determine the MDA, SOD, GSH-Px expression, ELISA to detect the expression of NF-κB, VEGF, ICAM-1 and PAH in brain tissues, and immunohistochemical method to detect JAK2, p-STAT3, AKT And ERK1/2 expression of the brain tissue ischemic penumbra area. Results Compared with sham group, model rats had severe neurological damage, larger cerebral infarction, necrosis, edema, inflammation, disorder of nerve cell arrangement, abnormal cell enlargement, vacuole-like changes, neuron reduction and other pathologies in brain tissues. The expression JeveJs of MDA, NF-κB, VEGF, PAI-1 and ICAM-1 in brain tissues of model group significantly increased, and the expression levels of GSH-Px and SOD were significantly reduced. Compared with model group, the neurological scores of rats in GX

BACKGROUND: Optimizing patients with advanced heart failure before orthotopic heart transplantation (OHT), especially in patients greater than 50 years old, is imperative to achieving successful post-transplant outcomes. Complications are well-described for patients bridged to transplant (BTT) with durable left ventricular assist device (LVAD) support. Given the lack of data available in older recipients after the recent increase in mechanical support use, we felt it crucial to report our center's one-year outcomes in older recipients after heart transplantation with percutaneously placed Impella 5.5 as a BTT. METHODS: Forty-nine OHT patients were supported with the Impella 5.5 intended as a bridge between December 2019 and October 2022 at Mayo Clinic in Florida. Data were extracted from the electronic health record at baseline and during their transplant episode of care after Institutional Review Boards approval as exempt for retrospective data collection. RESULTS: Thirty-eight patients aged 50 or older were supported with Impella 5.5 as BTT. Ten patients underwent heart and kidney transplantation within this cohort. The median age at OHT was 63 (58-68) years, with 32 male (84%) and six female patients (16%). Etiology was divided into ischemic (63%) and non-ischemic cardiomyopathy (37%). The baseline median ejection fraction was 19% (15-24). Most patients were in blood group O (60%), and 50% were diabetic. The average duration of support was 27 days (range 6-94). The median duration of follow-up is 488 days (185-693). For patients that have reached the 1-year follow-up timeframe (22 of 38, 58%), the 1-year post-transplant survival is 95%. CONCLUSION Our single-center data provides awareness for using the Impella 5.5 percutaneously placed axillary support device in older heart failure patients in cardiogenic shock as a bridge to transplantation. One-year survival outcomes after heart transplantation are excellent despite the older recipient's age and prolonged pre-transplant support.
